The rate of congenital heart defects is higher in newborns conceived using assisted reproductive technologies (ART) than in newborns conceived without assistance. This finding comes from a population-based cohort study led by Dr. Nona Sargisian, a gynecologist at the University of Gothenburg, Sweden, and colleagues, which was published in the European Heart Journal.

The researchers analyzed more than 7 million results of all live-born children in Denmark, Finland, Sweden, and Norway between 1984 and 2015. They found that congenital heart defects occurred more frequently in the ART newborn group (1.85%) than in naturally conceived newborns (1.15%).

The study also revealed that the risk for congenital heart defects in multiple births is higher than in single births, with and without the use of ART. However, the result that congenital heart defects occur more often in ART newborns remained significant when comparing single births from both groups (1.62% vs 1.11%).
 

Relatively Low Prevalence

Barbara Sonntag, MD, PhD, a gynecologist at Amedes Fertility Center in Hamburg, Germany, referred to a “clinically relevant risk increase” with a relatively low prevalence of the condition.

“When 1000 children are born, an abnormality occurs in 18 children after ART, compared with 11 children born after natural conception,” she told the Science Media Center.

Dr. Sonntag emphasized that the risk is particularly increased by a multiple pregnancy. A statement about causality is not possible based on the study, but multiple pregnancies are generally associated with increased risks during pregnancy and for the children.

The large and robust dataset confirms long-known findings, said Georg Griesinger, MD, PhD, medical director of the fertility centers of the University Medical Center Schleswig-Holstein in Lübeck and Manhagen, Germany.

The key figures can be found in single births, he explained. “Among single births conceived by ART, the rate of severe congenital heart defects was 1.62% compared with 1.11% in spontaneously conceived single births, an increase in risk by 1.19 times. For severe heart defects, the rate was 0.31% in ART single births, compared with 0.25% in spontaneously conceived single births.”

The increased risks are consistent with existing literature. Therefore, the current study does not reveal any new risk signals, said Dr. Griesinger.
 

Single Embryo Transfer

The “risks are small but present,” according to Michael von Wolff, MD, head of gynecological endocrinology and reproductive medicine at Bern University Hospital in Switzerland. “Therefore, ART therapy should only be carried out after exhausting conservative treatments,” he recommended. For example, ovarian stimulation with low-dose hormone preparations could be an option.

Dr. Griesinger pointed out that, in absolute numbers, all maternal and fetal or neonatal risks are significantly increased in twins and higher-order multiples, compared with the estimated risk association within the actual ART treatment.

“For this reason, reproductive medicine specialists have been advocating for single-embryo transfer for years to promote the occurrence of single pregnancies through ART,” said Dr. Griesinger.

The study “emphasizes the importance of single embryo transfer to avoid the higher risks associated with multiple pregnancies,” according to Rocío Núñez Calonge, PhD, scientific director of the International Reproduction Unit in Alicante, Spain.

Dr. Sonntag also sees a “strong additional call to avoid multiple pregnancies through a predominant strategy of single-embryo transfer in the data. The increased rate of childhood birth defects is already part of the information provided before assisted reproduction.”

High Blood Sugar May Drive Dementia, German Researchers Warn

Article Type

Fri, 07/26/2024 - 15:43

 

On World Brain Day (July 22, 2024), the German Society of Neurology (DGN) and the German Brain Foundation pointed out that too much sugar can harm the brain. The current results of the Global Burden of Diseases study shows that stroke and dementia are among the top 10 causes of death. A healthy, active lifestyle with sufficient exercise and sleep, along with the avoidance of harmful substances like alcohol, nicotine, or excessive sugar, protects the brain.

“Of course, the dose makes the poison as the brain, being the body’s powerhouse, needs glucose to function,” said Frank Erbguth, MD, PhD, president of the German Brain Foundation, in a press release from DGN and the German Brain Foundation. “However, with a permanent increase in blood sugar levels due to too many, too lavish meals and constant snacking on the side, we overload the system and fuel the development of neurologic diseases, particularly dementia and stroke.”

The per capita consumption of sugar was 33.2 kg in 2021/2022, which is almost twice the recommended amount. The German Nutrition Society recommends that no more than 10% of energy come from sugar. With a goal of 2000 kilocalories, that’s 50 g per day, or 18 kg per year. This total includes not only added sugar but also naturally occurring sugar, such as in fruits, honey, or juices.
 

What’s the Mechanism?

High blood sugar levels damage brain blood vessels and promote deposits on the vessel walls, thus reducing blood flow and nutrient supply to brain cells. This process can cause various limitations, as well as vascular dementia.

In Germany, around 250,000 people are diagnosed with dementia annually, and 15%-25% have vascular dementia. That proportion represents between 40,000 and 60,000 new cases each year.

In addition, glycosaminoglycans, which are complex sugar molecules, can directly impair cognition. They affect the function of synapses between nerve cells and, thus, affect neuronal plasticity. Experimental data presented at the 2023 American Chemical Society Congress have shown this phenomenon.

Twenty years ago, a study provided evidence that a diet high in fat and sugar disrupts neuronal plasticity and can impair the function of the hippocampus in the long term. A recent meta-analysis confirms these findings: Although mental performance improves at 2-12 hours after sugar consumption, sustained sugar intake can permanently damage cognitive function.

Diabetes mellitus can indirectly cause brain damage. Since the 1990s, it has been known that patients with type 2 diabetes have a significantly higher risk for dementia. It is suspected that glucose metabolism is also disrupted in neurons, thus contributing to the development of Alzheimer’s disease. Insulin also plays a role in the formation of Alzheimer’s plaques.

The Max Planck Institute for Metabolism Research demonstrated in 2023 that regular consumption of high-sugar and high-fat foods can change the brain. This leads to an increased craving for high-sugar and high-fat foods, which in turn promotes the development of obesity and type 2 diabetes.
 

Reduce Sugar Consumption

DGN and the German Brain Foundation advise minimizing sugar consumption. This process is often challenging, as even a small dose of sugar can trigger the gut to send signals to the brain via the vagus nerve, thus causing a strong craving for more sugar. “This could be the reason why some people quickly eat a whole chocolate bar after just one piece,” said Dr. Erbguth. In addition, dopamine, a “feel-good hormone,” is released in the brain when consuming sugar, thus leading to a desire for more.

“It is wise to break free from this cycle by largely avoiding sugar,” said Peter Berlit, MD, secretary general and spokesperson for DGN. “The effort is worth it, as 40% of all dementia cases and 90% of all strokes are preventable, with many of them linked to industrial sugar,” said Dr. Berlit. DGN and the German Brain Foundation support the call for a tax on particularly sugary beverages. They also pointed out that foods like yogurt or tomato ketchup contain sugar, and alcohol can also significantly raise blood sugar levels.

Which Emergencies Are Genuine Emergencies?

Article Type

Wed, 04/24/2024 - 13:03

 



— Crowded waiting rooms, long wait times, irritable patients, and aggression toward nursing staff and doctors are increasingly the reality in German emergency rooms. Clearly, emergencies belong in the emergency room. However, “In about half of all patients in the emergency room, there is no urgent medical emergency,” Norbert Schütz, MD, director of geriatrics and rheumatology at Helios Dr. Horst Schmidt Hospital in Wiesbaden, Germany, said at a press conference for the 130th Annual Meeting of the German Society of Internal Medicine (DGIM).

“In our daily medical practice, we repeatedly experience people either accessing our emergency departments and ambulances too quickly or lingering at home for too long when they have severe symptoms,” said Dr. Schütz, who organized the Patient Day during the Internist Congress.
 

DGIM Educates Patients

What is an emergency? “I think the public is quite well informed about conditions associated with loss of consciousness, severe pain, chest pain, or paralysis: Think stroke or heart attack. This is undoubtedly a success of recent years. The difficulty arises with everything in between. For instance, should I go to the hospital with severe headaches?” asked Dr. Schütz.

When is a patient a case for the emergency room, the physician on-call service, or the general practitioner? At the Patient Day in Wiesbaden, DGIM aims to educate and train interested parties with a dedicated lecture. The focus is on recognizing an emergency, specifically emergencies in children and mental illnesses.

“Our Patient Day aims to contribute to making the right decisions. We want to inform, answer questions, and alleviate fears,” said Dr. Schütz. Interested parties can refresh their emergency knowledge, tour ambulances, and have the equipment explained. The public also has the opportunity to learn about resuscitation techniques theoretically and practically.

“In general, the general practitioner should always be the first point of contact. They know their patients best and have the most background information,” explained Dr. Schütz. A trusting relationship is crucial for correctly assessing an unclear medical situation. “Should, for whatever reason, the general practitioner not be reachable, the physician on-call service can be reached,” said Dr. Schütz. It may happen, however, that neither the general practitioner nor the on-call physician is immediately available.
 

What Are Emergencies?

In cases of severe health impairment, urgency is required, and a severe emergency should be assumed in the following cases:

  • Chest pain
  • Circulatory disorder
  • Disorders of consciousness
  • Breathing difficulties
  • Sudden weakness or numbness/paralysis
  • Severe bleeding
  • Allergic shock

“In such cases, the emergency departments of the hospitals are available around the clock, and if necessary, an emergency doctor should be present during transportation to the hospital,” said Dr. Schütz.

Classifying emergencies is challenging, especially with children. “Children often find it difficult to clearly categorize or describe symptoms,” said Dr. Schütz. A situation is critical if, for example, the child’s breathing or consciousness is impaired.

Mental emergencies pose a particular challenge for patients and relatives because the patient and relatives are often overwhelmed by the situation. If there are suicidal thoughts, the patient should present him- or herself immediately to an emergency room.

“Patients who come to the emergency room because they cannot get appointments with their general practitioner or specialist, for whatever reason, are no emergency. We also see this in the emergency room from time to time,” said Dr. Schütz. Emergency rooms are not intended for this purpose. “And generally, these are not emergencies.”
 

 

 

Four of 10 Cases

The number of patients in emergency rooms has steadily increased in recent years. Statistically, only 4 out of 10 cases are genuine emergencies, as detailed surveys of patients in the emergency rooms of northern German hospitals have shown.

In the PiNo Nord cross-sectional study, Martin Scherer, MD, of University Hospital Hamburg-Eppendorf in Hamburg, Germany, and his team examined the reasons why patients visit the emergency room. They interviewed 1175 patients in five hospitals and documented the medical diagnoses. Patients classified as “immediately” or “very urgently” in need of treatment were excluded.

The surveyed patients were on average 41.8 years old, 52.9% were men, and 54.7% of the patients indicated a low urgency of treatment. About 41% of the patients visited the emergency room on their own initiative, 17% stated they were referred or entrusted by their general practitioner, and 8% were referred by a specialist in the emergency room.

The strongest predictors for low subjective treatment urgency were musculoskeletal trauma (odds ratio [OR], 2.18), skin afflictions (OR, 2.15), and the unavailability of an open general practitioner’s office (OR, 1.70).

According to Dr. Scherer and his colleagues, the reasons for visiting an emergency room are diverse and can be based on the perceived structural conditions and individual patient preferences in addition to the urgency of the health problem.

— Crowded waiting rooms, long wait times, irritable patients, and aggression toward nursing staff and doctors are increasingly the reality in German emergency rooms. Clearly, emergencies belong in the emergency room. However, “In about half of all patients in the emergency room, there is no urgent medical emergency,” Norbert Schütz, MD, director of geriatrics and rheumatology at Helios Dr. Horst Schmidt Hospital in Wiesbaden, Germany, said at a press conference for the 130th Annual Meeting of the German Society of Internal Medicine (DGIM).

“In our daily medical practice, we repeatedly experience people either accessing our emergency departments and ambulances too quickly or lingering at home for too long when they have severe symptoms,” said Dr. Schütz, who organized the Patient Day during the Internist Congress.
 

DGIM Educates Patients

What is an emergency? “I think the public is quite well informed about conditions associated with loss of consciousness, severe pain, chest pain, or paralysis: Think stroke or heart attack. This is undoubtedly a success of recent years. The difficulty arises with everything in between. For instance, should I go to the hospital with severe headaches?” asked Dr. Schütz.

When is a patient a case for the emergency room, the physician on-call service, or the general practitioner? At the Patient Day in Wiesbaden, DGIM aims to educate and train interested parties with a dedicated lecture. The focus is on recognizing an emergency, specifically emergencies in children and mental illnesses.

“Our Patient Day aims to contribute to making the right decisions. We want to inform, answer questions, and alleviate fears,” said Dr. Schütz. Interested parties can refresh their emergency knowledge, tour ambulances, and have the equipment explained. The public also has the opportunity to learn about resuscitation techniques theoretically and practically.

“In general, the general practitioner should always be the first point of contact. They know their patients best and have the most background information,” explained Dr. Schütz. A trusting relationship is crucial for correctly assessing an unclear medical situation. “Should, for whatever reason, the general practitioner not be reachable, the physician on-call service can be reached,” said Dr. Schütz. It may happen, however, that neither the general practitioner nor the on-call physician is immediately available.
 

What Are Emergencies?

In cases of severe health impairment, urgency is required, and a severe emergency should be assumed in the following cases:

  • Chest pain
  • Circulatory disorder
  • Disorders of consciousness
  • Breathing difficulties
  • Sudden weakness or numbness/paralysis
  • Severe bleeding
  • Allergic shock

“In such cases, the emergency departments of the hospitals are available around the clock, and if necessary, an emergency doctor should be present during transportation to the hospital,” said Dr. Schütz.

Classifying emergencies is challenging, especially with children. “Children often find it difficult to clearly categorize or describe symptoms,” said Dr. Schütz. A situation is critical if, for example, the child’s breathing or consciousness is impaired.

Mental emergencies pose a particular challenge for patients and relatives because the patient and relatives are often overwhelmed by the situation. If there are suicidal thoughts, the patient should present him- or herself immediately to an emergency room.

“Patients who come to the emergency room because they cannot get appointments with their general practitioner or specialist, for whatever reason, are no emergency. We also see this in the emergency room from time to time,” said Dr. Schütz. Emergency rooms are not intended for this purpose. “And generally, these are not emergencies.”
 

 

 

Four of 10 Cases

The number of patients in emergency rooms has steadily increased in recent years. Statistically, only 4 out of 10 cases are genuine emergencies, as detailed surveys of patients in the emergency rooms of northern German hospitals have shown.

In the PiNo Nord cross-sectional study, Martin Scherer, MD, of University Hospital Hamburg-Eppendorf in Hamburg, Germany, and his team examined the reasons why patients visit the emergency room. They interviewed 1175 patients in five hospitals and documented the medical diagnoses. Patients classified as “immediately” or “very urgently” in need of treatment were excluded.

The surveyed patients were on average 41.8 years old, 52.9% were men, and 54.7% of the patients indicated a low urgency of treatment. About 41% of the patients visited the emergency room on their own initiative, 17% stated they were referred or entrusted by their general practitioner, and 8% were referred by a specialist in the emergency room.

The strongest predictors for low subjective treatment urgency were musculoskeletal trauma (odds ratio [OR], 2.18), skin afflictions (OR, 2.15), and the unavailability of an open general practitioner’s office (OR, 1.70).

According to Dr. Scherer and his colleagues, the reasons for visiting an emergency room are diverse and can be based on the perceived structural conditions and individual patient preferences in addition to the urgency of the health problem.

What Are Platanus Cough and Thunderstorm Asthma?

Article Type
Changed
Wed, 04/17/2024 - 16:26

Because of climate change, heat waves, storms, heavy rainfalls, and floods are now occurring in areas that seldom experienced these phenomena before. “Extreme weather events are rare, but in terms of their extent, duration, and scale, they are unusual. And they are increasing due to climate change,” said Andrea Elmer, MD, an internal medicine and pulmonology specialist at the DKD Helios Clinic in Wiesbaden, Germany. She spoke at the Congress of the German Society for Pneumology and Respiratory Medicine.

Dr. Elmer referred to the 2023 status report by the Robert Koch Institute and the 2023 Synthesis Report by the Intergovernmental Panel on Climate Change, in which the likelihood of extreme weather events was acknowledged to be significantly higher than previously recognized. “Knowing about such extreme weather events is important to assess the consequences for our patients and to identify possible medical care needs,” said Dr. Elmer. She focused on the effects of platanus (plane tree) cough and thunderstorm asthma.
 

Platanus Cough

The severe symptoms of 40 students at a comprehensive school in Wiesbaden, including shortness of breath, coughing, and irritated eyes, led to a major operation involving the fire brigade and police on May 11, 2022. The symptoms worsened when the children left the building and waited in the schoolyard. Initially, a chemical attack with irritant gas was suspected because the school is located near an industrial area. There were no indications of a pollen cloud.

Eventually, doctors and firefighters found that the symptoms were caused by platanus cough, which is induced by the fine star-shaped hair found on young platanus leaves, bark, young branches, and buds. If strong winds move the leaves after prolonged dryness, these trichomes can break off when touched, creating platanus dust.

At that time, there were unusual climatic conditions. The temperature was 29 °C, it was dry, and wind gusts reached 50 km/h. The schoolyard was enclosed and densely planted with tall, old plane trees. Initial symptoms occurred in classrooms with open windows.

Twenty-five children had to be admitted to the hospital. Treatment included lorazepam and salbutamol. All students had normal oxygen levels, and the symptoms were reversed.
 

Cough or Allergy?

The clinical differential diagnosis for an allergy is quite simple, said Dr. Elmer. Platanus cough mainly shows symptoms of irritation, a feeling of a foreign body, and scratching in the eyes, throat, and nose. Coughing can also occur. In an allergy, there is often a runny nose and itching in the eyes and nose. Such allergic symptoms do not occur with platanus cough.

It should also be noted that the sensitization rates for a platanus allergy in Germany range between 5% and 11%. “Having so many platanus allergy sufferers in one place was relatively unlikely,” said Dr. Elmer.

She expects an increase in cases of platanus cough, especially in cities with dense construction, such as in narrow schoolyards. High concentrations of platanus dust can occur, especially when it is warm, dry, and windy. “Platanus cough does not occur every time we walk under plane trees. It strongly depends on warmth, dryness, and wind,” said Dr. Elmer.

Patients can protect themselves by avoiding skin and mucous membrane contact under appropriate climatic conditions and by wearing protective glasses and masks. Leaves and branches should not be swept but vacuumed. “Under no circumstances should plane trees be cut down. We need trees, especially in cities,” said Dr. Elmer. Moreover, the trichomes act as biofilters for air pollutants. In critical environments such as schoolyards, seasonal spraying of plane trees with a mixture of apple pectin and water can prevent the star hair from breaking off.
 

 

 

Thunderstorm Asthma

For patients with asthma, wildfires, storms, heavy rainfall, and thunderstorms can lead to exacerbations. Emergency room visits and hospital admissions generally increase after extreme weather events.

A study examining the consequences of the fires in California from 2004 to 2009, for example, reported that hospital visits related to asthma increased by 10.3%. Those related to respiratory problems increased by 3.3%. Infants and children up to age 5 years were most affected.

Thunderstorms are increasing because of global warming. Thunderstorm asthma arises under specific meteorological conditions. It typically occurs in patients with aeroallergies (eg, to pollen and fungal spores) in combination with thunderstorms and lightning. Large pollen grains, which normally remain in the upper airways, ascend into higher atmospheric layers and break apart due to updrafts. These very small particles are pushed back to ground level by downdrafts, enter the lower airways, and cause acute asthma.

Worldwide, cases of thunderstorm asthma are rare. About 30 events have been documented. Thunderstorm asthma was first observed in 1983 in Birmingham, England. Fungal spores were the trigger.

The most significant incident so far was a severe thunderstorm on November 21, 2016, in Melbourne, Australia. Worldwide attention was drawn to the storm because of an unusually high number of asthma cases. Within 30 hours, 3365 patients were admitted to emergency rooms. “This is also a high burden for a city with 4.6 million inhabitants,” said Dr. Elmer. Of the patients in Melbourne, 35 were admitted to the intensive care unit and 5 patients died.

Dr. Elmer calculated the corresponding number of patients for Wiesbaden and Mainz. “Assuming a population of 500,000 in this region, that would be 400 patients in emergency rooms within 30 hours, which would be a significant number.”

Such events are mainly observed in Australia, where two events per decade are expected. However, due to climate change, the risk could also increase in Europe, leading to more cases of thunderstorm asthma.
 

Risk Factors

The following environmental factors increase the risk:

  • High pollen concentrations in the days before a thunderstorm
  • Precipitation and high humidity, thunderstorms, and lightning
  • Sudden temperature changes
  • Increases in aeroallergen biomass and extreme weather events because of climate change

In Australia, grass pollen was often the trigger for thunderstorm asthma. In the United Kingdom, it was fungal spores. In Italy, olive pollen has a similar potential.

Patients with preexisting asthma, uncontrolled asthma, and high serum-specific immunoglobulin E levels are at risk. The risk is also increased for patients with poor compliance with inhaled steroid (ICS) therapy and for patients who have previously been hospitalized because of their asthma.

Patients with hay fever (ie, seasonal allergic rhinitis) have a significantly higher risk. As Dr. Elmer observed, 88% of patients in the emergency room in Melbourne had seasonal allergic rhinitis. “Fifty-seven percent of the patients in the emergency room did not have previously known asthma, but more than half showed symptoms indicating latent asthma. These patients had latent asthma but had not yet been diagnosed.”

Dr. Elmer emphasized how important it is not to underestimate mild asthma, which should be treated. For patients with hay fever, hyposensitization should be considered.
 

 

 

Reducing Risk

Many factors must come together for thunderstorm asthma to develop, according to Dr. Elmer. Because this convergence is difficult to predict, however, preparation and risk reduction are important. They consist of individual precautions and public health strategies.

The following steps can be taken at the individual level:

  • Identify risk groups, including patients with allergic rhinitis and high serum-specific immunoglobulin E levels. Patients with hay fever benefit from hyposensitization.
  • Avoid outdoor activities on risky days.
  • Diagnose asthma, and do not underestimate mild asthma. Improve therapy compliance with ICS therapy and use maintenance and reliever therapy. This way, the patient automatically increases the steroid dose with increased symptoms and is better protected against exacerbations.
  • Improve health literacy and understanding of asthma.

Thunderstorm asthma also affects healthcare professionals, Dr. Elmer warned. In Melbourne, 25% of responders themselves showed symptoms. Therefore, expect that some of these clinicians will also be unavailable.

Other steps are appropriate at the public health level. In addition to monitoring local pollen concentrations, one must identify risk groups, especially people working outdoors. “It is very difficult to predict an epidemic of thunderstorm asthma,” said Dr. Elmer. Therefore, it is important to increase awareness of the phenomenon and to develop an early warning system with emergency plans for patients and the healthcare system.

“Allergen immunotherapy is protective,” she added. “This has been well studied, and for Melbourne, it has been demonstrated. Patients with allergic rhinitis who had received immunotherapy were protected. These patients did not have to visit the emergency room. This shows that we can do something, and we should hyposensitize,” Dr. Elmer concluded.

Are E-Cigarettes Bad for the Heart?

Article Type
Changed
Tue, 04/16/2024 - 11:52

E-cigarettes entered the market as consumer products without comprehensive toxicological testing,based on the assessment that they were 95% less harmful than traditional cigarettes. Further, consumer dvertising suggests that e-cigarettes are a good alternative to conventional combustible cigarettes and can serve as a gateway to quitting smoking.

However, hen considering damage to the endothelium and toxicity, e-cigarettes have a negative impact like that of conventional cigarettes. Moreover, switching to e-cigarettes often leads to dual use, said Stefan Andreas, MD, director of the Lungenfachklinik in Immenhausen, Germany, at the Congress of the German Respiratory Society and Intensive Care Medicine. 
 

Subclinical Atherosclerosis

Because e-cigarettes have emerged relatively recently, long-term studies on their cardiac consequences are not yet available. Dr. Andreas explained that the impact on endothelial function is relevant for risk assessment. Endothelial function is a biomarker for early, subclinical atherosclerosis. “If endothelial function is impaired, the risk for heart attack and stroke is significantly increased 5-10 years later,” said Dr. Andreas.

The results of a crossover study showed reduced vascular elasticity after consuming both tobacco cigarettes and e-cigarettes. The study included 20 smokers, and endothelial function was measured using flow-mediated vasodilation.

Significant effects on the vessels were also found in a study of 31 participants who had never smoked. The study participants inhaled a nicotine-free aerosol from e-cigarettes. Before and after, parameters of endothelial function were examined using a 3.0-T MRI. After aerosol inhalation, the resistance index was 2.3% higher (P < .05), and flow-mediated vascular dilation was reduced by 34% (P < .001).

A recent review involving 372 participants from China showed that e-cigarettes lead to an increase in pulse wave velocity, with a difference of 3.08 (P < .001). “Pulse wave velocity is also a marker of endothelial function: The stiffer the vessels, the higher the pulse wave velocity,” said Dr. Andreas. The authors of the review concluded that “e-cigarettes should not be promoted as a healthier alternative to tobacco smoking.”
 

No Harmless Alternative

A recent review compared the effects of tobacco smoking and e-cigarettes. The results showed that vaping e-cigarettes causes oxidative stress, inflammation, endothelial dysfunction, and related cardiovascular consequences. The authors attributed the findings to overlapping toxic compounds in vapor and tobacco smoke and similar pathomechanical features of vaping and smoking. Although the toxic mixture in smoke is more complex, both e-cigarettes and tobacco cigarettes “impaired endothelial function to a similar extent,” they wrote. The authors attributed this finding to oxidative stress as the central mechanism.

“There is increasing evidence that e-cigarettes are not a harmless alternative to tobacco cigarettes,” wrote Thomas Münzel, MD, professor of cardiology at the University of Mainz and his team in their 2020 review, which examined studies in humans and animals. They provided an overview of the effects of tobacco/hookah smoking and e-cigarette vaping on endothelial function. They also pointed to emerging adverse effects on the proteome, transcriptome, epigenome, microbiome, and circadian clock.

Finally, a toxicological review of e-cigarettes also found alarmingly high levels of carcinogens and toxins that could have long-term effects on other organs, including the development of neurological symptoms, lung cancer, cardiovascular diseases, and cavities.

Dr. Andreas observed that even small amounts, such as those obtained through secondhand smoking, can be harmful. In 2007, Dr. Andreas and his colleagues showed that even low exposure to tobacco smoke can lead to a significant increase in cardiovascular events.
 

 

 

Conflicts of Interest 

Dr. Andreas recommended closely examining the studies that suggest that e-cigarettes are less risky. “It is noticeable that there is a significant difference depending on whether publications were supported by the tobacco industry or not,” he emphasized.

Danish scientists found that a conflict of interest (COI) has a strong influence on study results. “In studies without a COI, e-cigarettes are found to cause damage 95% of the time. In contrast, when there is a strong conflict of interest, the result is often ‘no harm,’” said Dr. Andreas.

This effect is quite relevant for the discussion of e-cigarettes. “If scientists make a critical statement in a position paper, there will always be someone who says, ‘No, it’s different, there are these and those publications.’ The true nature of interest-driven publications on e-cigarettes is not always easy to discern,” said Dr. Andreas.
 

No Gateway to Quitting 

E-cigarettes are used in clinical studies for tobacco cessation. The results of a randomized study showed that significantly more smokers who were switched to e-cigarettes quit smoking, compared with controls. But there was no significant difference in complete smoking cessation between groups. Moreover, 45% of smokers who switched to e-cigarettes became dual users, compared with 11% of controls.

“Translating these results means that for one person who quits smoking by using e-cigarettes, they gain five people who use both traditional cigarettes and e-cigarettes,” explained Dr. Andreas.

In their recent review, Münzel and colleagues pointed out that the assessment that e-cigarettes could help with quitting might be wrong. Rather, it seems that “e-cigarettes have the opposite effect.” They also note that the age of initiation for e-cigarettes is generally lower than for tobacco cigarettes: Consumption often starts at age 13 or 14 years. And the consumption of e-cigarettes among children and adolescents increased by 7% from 2016 to 2023.

A meta-analysis published at the end of February also shows that e-cigarettes are about as dangerous as tobacco cigarettes. They are more dangerous than not smoking, and dual use is more dangerous than tobacco cigarettes alone. “There is a need to reassess the assumption that e-cigarette use provides substantial harm reduction across all cigarette-caused diseases, particularly accounting for dual use,” wrote the authors.

“One must always consider that e-cigarettes have only been available for a relatively short time. We can only see the cumulative toxicity in 10, 20 years when we have patients who have smoked e-cigarettes only for 20 years,” said Dr. Andreas. Ultimately, however, e-cigarettes promote dual use and, consequently, additive toxicity.
 

Nicotine Replacement Therapies 

Quitting smoking reduces the risk of cardiovascular events and premature death by 40%, even among patients with cardiovascular disease, according to a Cochrane meta-analysis. Smoking cessation reduces the risk for cardiovascular death by 39%, the risk for major adverse cardiovascular events by 43%, the risk for heart attack by 36%, the risk for stroke by 30%, and overall mortality by 40%.

Quitting smoking is the most effective measure for risk reduction, as a meta-analysis of 20 studies in patients with coronary heart disease found. Smoking cessation was associated with a 36% risk reduction compared with 29% risk reduction for statin therapy, 23% risk reduction with beta-blockers and ACE inhibitors and 15% risk reduction with aspirin.

Dr. Andreas emphasized that nicotine replacement therapies are well-researched and safe even in cardiovascular disease, as shown by a US study that included patients who had sustained a heart attack. A group of the participants was treated with nicotine patches for 10 weeks, while the other group received a placebo. After 14 weeks, 21% of the nicotine patch group achieved abstinence vs 9% of the placebo group (P = .001). Transdermal nicotine application does not lead to a significant increase in cardiovascular events in high-risk patients.

The German “Nonsmoker Heroes” app has proven to be an effective means of behavioral therapeutic coaching. A recent study of it included 17 study centers with 661 participants. About 21% of the subjects had chronic obstructive pulmonary disease, 19% had asthma. Smoking onset occurred at age 16 years. The subjects were highly dependent: > 72% had at least moderate dependence, > 58% had high to very high dependence, and the population had an average of 3.6 quit attempts. The odds ratio for self-reported abstinence was 2.2 after 6 months. “The app is not only effective, but also can be prescribed on an extrabudgetary basis,” said Dr. Andreas.

E-cigarettes entered the market as consumer products without comprehensive toxicological testing,based on the assessment that they were 95% less harmful than traditional cigarettes. Further, consumer dvertising suggests that e-cigarettes are a good alternative to conventional combustible cigarettes and can serve as a gateway to quitting smoking.

However, hen considering damage to the endothelium and toxicity, e-cigarettes have a negative impact like that of conventional cigarettes. Moreover, switching to e-cigarettes often leads to dual use, said Stefan Andreas, MD, director of the Lungenfachklinik in Immenhausen, Germany, at the Congress of the German Respiratory Society and Intensive Care Medicine. 
 

Subclinical Atherosclerosis

Because e-cigarettes have emerged relatively recently, long-term studies on their cardiac consequences are not yet available. Dr. Andreas explained that the impact on endothelial function is relevant for risk assessment. Endothelial function is a biomarker for early, subclinical atherosclerosis. “If endothelial function is impaired, the risk for heart attack and stroke is significantly increased 5-10 years later,” said Dr. Andreas.

The results of a crossover study showed reduced vascular elasticity after consuming both tobacco cigarettes and e-cigarettes. The study included 20 smokers, and endothelial function was measured using flow-mediated vasodilation.

Significant effects on the vessels were also found in a study of 31 participants who had never smoked. The study participants inhaled a nicotine-free aerosol from e-cigarettes. Before and after, parameters of endothelial function were examined using a 3.0-T MRI. After aerosol inhalation, the resistance index was 2.3% higher (P < .05), and flow-mediated vascular dilation was reduced by 34% (P < .001).

A recent review involving 372 participants from China showed that e-cigarettes lead to an increase in pulse wave velocity, with a difference of 3.08 (P < .001). “Pulse wave velocity is also a marker of endothelial function: The stiffer the vessels, the higher the pulse wave velocity,” said Dr. Andreas. The authors of the review concluded that “e-cigarettes should not be promoted as a healthier alternative to tobacco smoking.”

Experts Aim to Use Brown Fat to Burn Fat More Effectively

Article Type

Can brown fat tissue be targeted for fat burning? Current findings on this topic were presented at the 67th German Congress of Endocrinology. Some statistics highlighted the need. Approximately 53% of the German population (almost 47% of women and 60% of men) are overweight (including obesity). Obesity is present in 19% of adults. The condition not only results in a shorter life expectancy but also increases the risk for cancer, diabetes, and cardiovascular diseases.

“The current treatment focuses on reducing energy intake, for example, through GLP-1 [glucagon-like peptide 1] agonists, which induce a feeling of satiety and significantly reduce body weight,” explained PD Tim Hollstein, MD, of the Institute of Diabetes and Clinical Metabolic Research at the University Hospital Schleswig-Holstein in Kiel, Germany. But the effect of weight loss injections only lasts for the duration of their application, and they are expensive.

“A potentially more sustainable treatment option would be to increase energy expenditure,” said Dr. Hollstein. He explained the role of brown fat tissue at a press conference for the German Society of Endocrinology (DGE) Congress.

While white fat tissue stores energy and can make up to 50% of a person’s body mass, brown fat tissue (brown adipose tissue [BAT]) burns energy to generate heat. The many mitochondria in brown fat tissue give it its characteristic brown color. “Brown fat tissue is like a heater for our body and kicks in when we are cold,” said Dr. Hollstein.

Brown fat tissue is primarily found in babies who cannot generate heat through muscle shivering. It has only been known for about 15 years that adults also possess brown fat. PET scans have shown that women generally have a higher amount of BAT and a higher energy intake capacity. The chance of discovering brown fat tissue was lower in older patients (P < .001), at higher outside temperatures (P = .02), in older patients with higher body mass index (P = .007), and if the patients were taking beta-blockers (P < .001).

Two Metabolic Types

An average person has about 100-300 g of brown fat tissue, mainly around the neck and collarbone and along the spine. Interestingly, just 50 g of active BAT can burn up to 300 kcal/d. “That’s roughly equivalent to a chocolate brownie,” said Dr. Hollstein. Lean individuals have more active BAT than overweight people, suggesting that BAT plays a role in our body weight.

In addition to its “heating function,” BAT also produces hormones, so-called “batokines,” which influence metabolism and organs such as the heart and liver. An example of a batokine is the hormone fibroblast growth factor 21, which promotes fat burning in the liver and can protect against fatty liver.

Recent studies have shown that BAT is activated not only by cold but also by food intake. BAT thus contributes to so-called “diet-induced thermogenesis,” which is the energy the body needs for digestion. Some people have a higher digestive energy than others, despite having the same food intake. They burn excess calories and can thus protect themselves from being overweight.

“There are people who have a more wasteful metabolism and people who have a more economical metabolic type, meaning they have less brown fat,” explained Dr. Hollstein. Interestingly, BAT also seems to induce a feeling of satiety in the brain, which could be significant for regulating food intake.
 

 

 

Activating Brown Fat

According to Dr. Hollstein, batokines probably have diverse effects and influence not only satiety and inflammatory processes but also cardiovascular diseases, diabetes, and fatty liver. It is important to research what distinguishes patients who have a lot of brown fat tissue from those who have little.

BAT can be trained and increased through regular cold exposure, which subsequently melts body fat. In a Japanese study, acute cold exposure (19 °C) for 2 hours increased energy consumption. Cold-induced increases in energy consumption correlated strongly with BAT activity, regardless of age and fat-free mass. Daily 2-hour cold exposure at 17 °C for 6 weeks led to a parallel increase in BAT activity.

“You can train brown fat tissue through cold exposure, which also leads to improvements in metabolism and a slight loss of fat mass, but the effect is very small,” explained Dr. Hollstein. The changes in metabolism are significant. Blood lipid levels improve, insulin sensitivity increases, and inflammation values decrease, according to Dr. Hollstein.

Evidence also indicates that capsaicin contained in chili peppers can activate brown fat tissue. However, the effects are small, and so far, there is no evidence that consumption can help with weight loss.
 

Medications Activate Brown Fat

Because permanent cold and daily consumption of chili peppers are not a real option, especially because the effects on BAT are rather small, research is being conducted to find drugs that activate brown fat tissue.

Preliminary results come from the United States. Mirabegron, originally developed for an overactive bladder, can selectively activate BAT and boost metabolism. A single injection of mirabegron activated BAT and increased energy consumption in the short term. Plasma levels of high-density lipoproteins cholesterol and apolipoprotein A1 increased, as did the total amount of bile acids.

The hormone adiponectin, which has antidiabetic and anti-inflammatory properties, also increased and was 35% higher after the study’s completion. An intravenous glucose tolerance test showed higher insulin sensitivity, glucose efficiency, and insulin secretion.

After 4 weeks of therapy in healthy women, brown fat tissue increased, but the participants did not lose weight or body fat.

New studies have also identified the widely used drug salbutamol as a BAT activator. However, the problem with both drugs is that they have side effects such as a faster heartbeat and increased blood pressure.

As Dr. Hollstein reported, attempts have also been made to transplant brown fat tissue into overweight mice. However, in most cases, the brown fat tissue was converted into white fat.

In Dr. Hollstein’s estimation, BAT offers enormous potential in the treatment of obesity and related metabolic diseases, and its activation could make a significant contribution to combating the obesity epidemic. “I believe that brown fat tissue will occupy us even more in the future. In combination with weight loss injections, increased energy consumption through brown fat tissue could have synergistic effects,” he concluded.

Preliminary results come from the United States. Mirabegron, originally developed for an overactive bladder, can selectively activate BAT and boost metabolism. A single injection of mirabegron activated BAT and increased energy consumption in the short term. Plasma levels of high-density lipoproteins cholesterol and apolipoprotein A1 increased, as did the total amount of bile acids.

The hormone adiponectin, which has antidiabetic and anti-inflammatory properties, also increased and was 35% higher after the study’s completion. An intravenous glucose tolerance test showed higher insulin sensitivity, glucose efficiency, and insulin secretion.

After 4 weeks of therapy in healthy women, brown fat tissue increased, but the participants did not lose weight or body fat.

New studies have also identified the widely used drug salbutamol as a BAT activator. However, the problem with both drugs is that they have side effects such as a faster heartbeat and increased blood pressure.

As Dr. Hollstein reported, attempts have also been made to transplant brown fat tissue into overweight mice. However, in most cases, the brown fat tissue was converted into white fat.

In Dr. Hollstein’s estimation, BAT offers enormous potential in the treatment of obesity and related metabolic diseases, and its activation could make a significant contribution to combating the obesity epidemic. “I believe that brown fat tissue will occupy us even more in the future. In combination with weight loss injections, increased energy consumption through brown fat tissue could have synergistic effects,” he concluded.

Can brown fat tissue be targeted for fat burning? Current findings on this topic were presented at the 67th German Congress of Endocrinology. Some statistics highlighted the need. Approximately 53% of the German population (almost 47% of women and 60% of men) are overweight (including obesity). Obesity is present in 19% of adults. The condition not only results in a shorter life expectancy but also increases the risk for cancer, diabetes, and cardiovascular diseases.

“The current treatment focuses on reducing energy intake, for example, through GLP-1 [glucagon-like peptide 1] agonists, which induce a feeling of satiety and significantly reduce body weight,” explained PD Tim Hollstein, MD, of the Institute of Diabetes and Clinical Metabolic Research at the University Hospital Schleswig-Holstein in Kiel, Germany. But the effect of weight loss injections only lasts for the duration of their application, and they are expensive.

“A potentially more sustainable treatment option would be to increase energy expenditure,” said Dr. Hollstein. He explained the role of brown fat tissue at a press conference for the German Society of Endocrinology (DGE) Congress.

While white fat tissue stores energy and can make up to 50% of a person’s body mass, brown fat tissue (brown adipose tissue [BAT]) burns energy to generate heat. The many mitochondria in brown fat tissue give it its characteristic brown color. “Brown fat tissue is like a heater for our body and kicks in when we are cold,” said Dr. Hollstein.

Brown fat tissue is primarily found in babies who cannot generate heat through muscle shivering. It has only been known for about 15 years that adults also possess brown fat. PET scans have shown that women generally have a higher amount of BAT and a higher energy intake capacity. The chance of discovering brown fat tissue was lower in older patients (P < .001), at higher outside temperatures (P = .02), in older patients with higher body mass index (P = .007), and if the patients were taking beta-blockers (P < .001).

Two Metabolic Types

An average person has about 100-300 g of brown fat tissue, mainly around the neck and collarbone and along the spine. Interestingly, just 50 g of active BAT can burn up to 300 kcal/d. “That’s roughly equivalent to a chocolate brownie,” said Dr. Hollstein. Lean individuals have more active BAT than overweight people, suggesting that BAT plays a role in our body weight.

In addition to its “heating function,” BAT also produces hormones, so-called “batokines,” which influence metabolism and organs such as the heart and liver. An example of a batokine is the hormone fibroblast growth factor 21, which promotes fat burning in the liver and can protect against fatty liver.

Recent studies have shown that BAT is activated not only by cold but also by food intake. BAT thus contributes to so-called “diet-induced thermogenesis,” which is the energy the body needs for digestion. Some people have a higher digestive energy than others, despite having the same food intake. They burn excess calories and can thus protect themselves from being overweight.

“There are people who have a more wasteful metabolism and people who have a more economical metabolic type, meaning they have less brown fat,” explained Dr. Hollstein. Interestingly, BAT also seems to induce a feeling of satiety in the brain, which could be significant for regulating food intake.
 

 

 

Activating Brown Fat

According to Dr. Hollstein, batokines probably have diverse effects and influence not only satiety and inflammatory processes but also cardiovascular diseases, diabetes, and fatty liver. It is important to research what distinguishes patients who have a lot of brown fat tissue from those who have little.

BAT can be trained and increased through regular cold exposure, which subsequently melts body fat. In a Japanese study, acute cold exposure (19 °C) for 2 hours increased energy consumption. Cold-induced increases in energy consumption correlated strongly with BAT activity, regardless of age and fat-free mass. Daily 2-hour cold exposure at 17 °C for 6 weeks led to a parallel increase in BAT activity.

“You can train brown fat tissue through cold exposure, which also leads to improvements in metabolism and a slight loss of fat mass, but the effect is very small,” explained Dr. Hollstein. The changes in metabolism are significant. Blood lipid levels improve, insulin sensitivity increases, and inflammation values decrease, according to Dr. Hollstein.

Evidence also indicates that capsaicin contained in chili peppers can activate brown fat tissue. However, the effects are small, and so far, there is no evidence that consumption can help with weight loss.

Hormones and Viruses Influence Each Other: Consider These Connections in Your Patients

Article Type

Mon, 03/18/2024 - 15:14

Stefan Bornstein, MD, PhD, professor, made it clear during a press conference at the 67th Congress of the German Society of Endocrinology (DGE) that there is more than one interaction between them. Nowadays, one can almost speak of an “endocrine virology and even of the virome as an additional, hormonally metabolically active gland,” said Dr. Bornstein, who will receive the Berthold Medal from the DGE in 2024.

Many questions remain unanswered: “We need a better understanding of the interaction of hormone systems with infectious agents — from basics to therapeutic applications,” emphasized the director of the Medical Clinic and Polyclinic III and the Center for Internal Medicine at the Carl Gustav Carus University Hospital, Dresden, Germany.

If infectious diseases could trigger diabetes and other metabolic diseases, this means that “through vaccination programs, we may be able to prevent the occurrence of common metabolic diseases such as diabetes,” said Dr. Bornstein. He highlighted that many people who experienced severe COVID-19 during the pandemic, or died from it, exhibited diabetes or a pre-metabolic syndrome.

“SARS-CoV-2 has utilized an endocrine signaling pathway to invade our cells and cause damage in the organ systems and inflammation,” said Dr. Bornstein. Conversely, it is now known that infections with coronaviruses or other infectious agents like influenza can significantly worsen metabolic status, diabetes, and other endocrine diseases.
 

SARS-CoV-2 Infects the Beta Cells

Data from the COVID-19 pandemic showed that the likelihood of developing type 1 diabetes significantly increases with a SARS-CoV-2 infection. Researchers led by Dr. Bornstein demonstrated in 2021 that SARS-CoV-2 can infect the insulin-producing cells of the organ. They examined pancreatic tissue from 20 patients who died from COVID-19 using immunofluorescence, immunohistochemistry, RNA in situ hybridization, and electron microscopy.

They found viral SARS-CoV-2 infiltration of the beta cells in all patients. In 11 patients with COVID-19, the expression of ACE2, TMPRSS, and other receptors and factors like DPP4, HMBG1, and NRP1 that can facilitate virus entry was examined. They found that even in the absence of manifest newly onset diabetes, necroptotic cell death, immune cell infiltration, and SARS-CoV-2 infection of the pancreas beta cells can contribute to varying degrees of metabolic disturbance in patients with COVID-19.

In a report published in October 2020, Tim Hollstein, MD, from the Institute for Diabetology and Clinical Metabolic Research at UKSH in Kiel, Germany, and colleagues described the case of a 19-year-old man who developed symptoms of insulin-dependent diabetes after a SARS-CoV-2 infection, without the presence of autoantibodies typical for type 1 diabetes.

The man presented to the emergency department with diabetic ketoacidosis, a C-peptide level of 0.62 µg/L, a blood glucose concentration of 30.6 mmol/L (552 mg/dL), and an A1c level of 16.8%. The patient’s history revealed a probable SARS-CoV-2 infection 5-7 weeks before admission, based on a positive antibody test against SARS-CoV-2.
 

Some Viruses Produce Insulin-Like Proteins

Recent studies have shown that some viruses can produce insulin-like proteins or hormones that interfere with the metabolism of the affected organism, reported Dr. Bornstein. In addition to metabolic regulation, these “viral hormones” also seem to influence cell turnover and cell death.

Dr. Bornstein pointed out that antiviral medications can delay the onset of type 1 diabetes by preserving the function of insulin-producing beta cells. It has also been shown that conventional medications used to treat hormonal disorders can reduce the susceptibility of the organism to infections — such as antidiabetic preparations like DPP-4 inhibitors or metformin.

In a review published in 2023, Nikolaos Perakakis, MD, professor, research group leader at the Paul Langerhans Institute Dresden, Dresden, Germany, Dr. Bornstein, and colleagues discussed scientific evidence for a close mutual dependence between various virus infections and metabolic diseases. They discussed how viruses can lead to the development or progression of metabolic diseases and vice versa and how metabolic diseases can increase the severity of a virus infection.
 

Viruses Favor Metabolic Diseases...

Viruses can favor metabolic diseases by, for example, influencing the regulation of cell survival and specific signaling pathways relevant for cell death, proliferation, or dedifferentiation in important endocrine and metabolic organs. Viruses are also capable of controlling cellular glucose metabolism by modulating glucose transporters, altering glucose uptake, regulating signaling pathways, and stimulating glycolysis in infected cells.

Due to the destruction of beta cells, enteroviruses, but also the mumps virus, parainfluenza virus, or human herpes virus 6, are associated with the development of diabetes. The timing of infection often precedes or coincides with the peak of development of islet autoantibodies. The fact that only a small proportion of patients actually develop type 1 diabetes suggests that genetic background, and likely the timing of infection, play an important role.
 

...And Metabolic Diseases Influence the Course of Infection

Infection with hepatitis C virus (HCV), on the other hand, is associated with an increased risk for type 2 diabetes, with the risk being higher for older individuals with a family history of diabetes. The negative effects of HCV on glucose balance are mainly attributed to increased insulin resistance in the liver. HCV reduces hepatic glucose uptake by downregulating the expression of glucose transporters and additionally impairs insulin signal transduction by inhibiting the PI3K/Akt signaling pathway.

People with obesity, diabetes, or insulin resistance show significant changes in the innate and adaptive functions of the immune system. Regarding the innate immune system, impaired chemotaxis and phagocytosis of neutrophils have been observed in patients with type 2 diabetes.

In the case of obesity, the number of natural killer T cells in adipose tissue decreases, whereas B cells accumulate in adipose tissue and secrete more proinflammatory cytokines. Longitudinal multiomics analyses of various biopsies from individuals with insulin resistance showed a delayed immune response to respiratory virus infections compared with individuals with normal insulin sensitivity.

Ebola Vaccine Saves Lives Even After Exposure

Article Type
Changed
Fri, 03/01/2024 - 16:24

The Ervebo vaccine not only reduces the risk for Ebola infection but also halves mortality rates. This is the result of a study published in The Lancet Infectious Diseases.

Rebecca Coulborn, an epidemiologist at Epicentre in Paris, France, and colleagues analyzed data collected during the 10th Ebola epidemic in the Democratic Republic of the Congo. Their analysis revealed that among the 2279 patients with confirmed Ebola who were admitted to an Ebola health facility between July 27, 2018, and April 27, 2020, the mortality risk was 56% for unvaccinated patients. In vaccinated patients, however, it was only 25%. The reduced mortality applied to all patients, regardless of age and gender.

The study was funded by Doctors Without Borders. For data collection, Epicentre, the epidemiological division of Doctors Without Borders, collaborated with the Institut National de Recherche Biomédicale and the Ministry of Health of the Democratic Republic of the Congo.

The study authors focused on the Ervebo vaccine, which is approved for use against Zaire ebolavirus in the European Union, the United States, and some African countries, among others. It is the only Ebola vaccine currently recommended for use during an epidemic. It is administered intramuscularly as a single dose and is approved for adults aged 18 years and older.

The vaccine is primarily recommended for ring vaccination of individuals at a high risk for infection during an epidemic. In studies, the vaccine has been used for ring vaccinations among contacts of diagnosed cases since the end of the Ebola outbreak in West Africa in 2014 and 2015 and since 2018 in the Democratic Republic of the Congo.

The preliminary estimated vaccine effectiveness 10 days after vaccination is 97.5%-100%. The duration of protection is unknown. Individuals who became ill despite vaccination typically experienced a milder course of illness.

Although people should be vaccinated as early as possible during Ebola outbreaks, the results of the Epicentre study showed that the vaccine still protects against the risk for infection even when administered after exposure to the virus.

Furthermore, Dr. Coulborn and her team found no antagonistic effect between vaccination and Ebola treatment in their analysis. “Vaccination following exposure to a person infected with Ebola still provides significant protection against death, even if administered shortly before the onset of symptoms,” said study author Dr. Coulborn in a press release from Doctors Without Borders.

Patients Want the Facts Delivered in a Personal Story

Article Type

Wed, 02/21/2024 - 21:16

Poor communication between physician and patient can cause a lot of harm, according to Joseph N. Cappella, PhD, Gerald R. Miller Professor Emeritus of Communication at the University of Pennsylvania in Philadelphia, and Richard N. Street Jr, PhD, professor of communication and media science at Texas A&M University in Houston, Texas. When a physician and patient talk past each other, it may impair the patient’s compliance with preventive measures, screening, and treatment; undermine the physician-patient relationship; exacerbate fears and concerns; and possibly lead patients to rely on misleading, incomplete, or simply incorrect information, turning away from evidence-based medicine.

Drs. Cappella and Street made these points in an essay recently published in JAMA. The essay marks the beginning of the JAMA series Communicating Medicine.

“Helping clinicians deliver accurate information more effectively can lead to better-informed patients,” wrote Anne R. Cappola, MD, professor of endocrinology, diabetes, and metabolism at the University of Pennsylvania, and Kirsten Bibbins-Domingo, MD, PhD, professor of medicine at the University of California, San Francisco, in an accompanying editorial. Drs. Cappola and Bibbins-Domingo also are editors of JAMA.

To establish a common understanding between physician and patient, Drs. Cappella and Street identified the following four responsibilities of the physician:

  • Discover what the patient understands and why
  • Provide accurate information in an understandable manner
  • Promote the credibility of the information
  • Verify whether the patient has understood.

“Research has shown that although medical facts need to be the basis for the clinician’s core message, those facts are more effectively communicated in a patient-clinician relationship characterized by trust and cooperation and when the information is presented in a manner that fosters patient understanding,” wrote Drs. Cappella and Street. This approach includes using interpreters for patients who do not fluently speak the physician’s language and supplementing explanations with simple written information, images, and videos.

Patients generally believe their physician’s information, and most patients view their physicians as a trustworthy source. Trust is based on the belief that the physician has the patient’s best interests at heart.

However, patients may be distrustful of their physician’s information if it contradicts their own belief system or personal experiences or because they inherently distrust the medical profession.

In addition, patients are less willing to accept explanations and recommendations if they feel misunderstood, judged, discriminated against, or rushed by the physician. The basis for effective communication is a relationship with patients that is built on trust and respect. Empirically supported strategies for expressing respect and building trust include the following:

  • Affirming the patient’s values
  • Anticipating and addressing false or misleading information
  • Using simple, jargon-free language
  • Embedding facts into a story, rather than presenting the scientific evidence dryly.

“Conveying factual material using these techniques makes facts more engaging and memorable,” wrote Drs. Cappella and Street. It is crucial to inquire about and consider the patient’s perspective, health beliefs, assumptions, concerns, needs, and stories in the conversation.

Personalized nutrition therapy promotes diabetes remission

Article Type
Changed
Mon, 12/11/2023 - 11:11

LEIPZIG, GERMANY — For patients newly diagnosed with type 2 diabetes, nutrition therapy is highly effective at achieving remission. “The greater the reduction in body weight, the higher the chances that blood sugar levels will normalize,” Diana Rubin, MD, said at the fall press conference of the German Diabetes Society (DDG). Dr. Rubin is conference president and chief physician of the Center for Nutritional Medicine and Diabetology at Vivantes Humboldt Hospital and the Spandau Hospital, Berlin, Germany. 

Because of the development of modern medicines, nutrition therapy has increasingly been pushed into the background over the past 50 years. However, nutrition therapy and weight reduction can effectively delay diabetes for years, said Dr. Rubin. The patients are healthy, without being healed. 

Nevertheless, the remission is rarely permanent. Most of the patients develop type 2 diabetes again after 5 years. 

Personalized Nutrition Therapy

It is not just developments in medicine that have pushed nutrition therapy into the background. Another contributing factor is that statutory health insurance companies do not cover personalized nutrition counseling as standard, said Dr. Rubin. 

Modern research in nutrition therapy has shown that patients with diabetes should receive personalized treatment. However, this idea is not taken into consideration in current diabetes training programs, which are the only forms of nutrition therapy covered by statutory health insurance companies. 

Instead, nutrition information is mostly conveyed through group training sessions. Individuals do not necessarily find each other again. What’s more, these sessions are seldom led by nutrition experts. “It is rarely helpful to use a ‘one size fits all’ approach, as is often the case with these group training sessions,” said Dr. Rubin. 

The DiRECT study, in which patients reduced their weight by 15 kg and achieved remission rates of almost 90%, is an example of how nutrition therapy can be highly effective. This is especially true if the aims and methods are determined on an individual basis and if there is frequent contact with a therapist. German and international guidelines, including the DDG’s best practice guides from 2022, highlight the importance of personalized nutrition therapy. 

Telemedicine Encourages Adherence

“It is very important to consider the current living situation of the person concerned,” said Dr. Rubin. “It is important to set small objectives that can also be implemented in everyday life.” This can only succeed with a professional face-to-face consultation. “Achieving this objective then also becomes realistic — i.e., losing 10% to 15% body weight and maintaining this loss,” she said. “Long-term monitoring is needed to maintain this weight.” 

Weight reduction methods should generally be determined according to the preferences of the person concerned, since dietary habits and environments are personal. For example, reducing the intake of carbohydrates and fats, intermittent fasting, or using meal replacement drinks can all be considered. 

New data also show that digital apps available on prescription (DiGA) can be helpful for support; this idea is reflected in the DDG’s nutrition best practice guides for patients with type 2 diabetes. 

“Studies show that adherence is highly dependent on the amount of contact with therapists and the long-term nature of the treatment,” said Dr. Rubin. She referred to the need for long-term monitoring, during which the patient can be repeatedly reminded of the therapeutic objective. “In this respect, I see a lot of potential in digital apps, and also in telemedicine, to cater to the short-term contact with the person concerned.” 

A 2015 meta-analysis of 92 studies revealed a significant reduction in A1c for patients with type 1 or type 2 diabetes when using telemedicine nutrition therapy. Dr. Rubin frequently prescribes DiGAs, which are approved for obesity, “simply because I can recognize it makes it easier for many patients to stick to their goals.” 

Dr. Rubin also recommends connecting with sport groups and self-help groups. “Maintaining the weight is a long-term project.” 

 

 

Abdominal Fat Decisive

Prediabetes is a precursor to type 2 diabetes and entails an increased risk of heart attack, kidney and eye diseases, and various kinds of cancer. To date, physicians have tried to delay the onset of type 2 diabetes by aiming to reduce the weight of patients with prediabetes. However, scientists at the German Center for Diabetes Research showed with the Prediabetes Lifestyle Intervention Study that abdominal fat plays an important role in the remission of prediabetes. 

The 1-year program with a healthy diet and increased physical activity was followed by 1105 patients with prediabetes. When every subject lost at least 5% of their weight, it turned out that some achieved remission, and others did not. 

People who achieved remission exhibited better insulin sensitivity and had lost more visceral abdominal fat. Visceral abdominal fat can influence insulin sensitivity, not least by an inflammatory reaction in the fatty tissue. 

Reducing visceral abdominal fat is clearly crucially important in achieving prediabetes remission. Subjects who achieved remission in the study had a strongly reduced risk for type 2 diabetes for up to 2 years after the end of the program. They had improved kidney function, and their blood vessels were in better condition. 

Waist Circumference 

According to the new results, the chances of remission increase if body weight is reduced by 5% and waist circumference is reduced by around 4 cm in women and 7 cm in men. 

“Based on the new data, remission should be the new therapeutic objective in people with prediabetes. This could potentially change clinical practice and minimize the complication rate for our patients, both male and female,” said author Reiner Jumpertz-von Schwartzenberg, MD, a researcher at the Tübingen University Hospital in Germany. 

Prediabetes remission can be assumed if the fasting blood glucose falls below 100 mg/dL (5.6 mmol/L), the 2-hour glucose below 140 mg/dL (7.8 mmol/L), and the A1c value below 5.7%. From the new findings, it can be seen that the chances of remission increase the more the body weight decreases.  

Dr. Jumpertz-von Schwartzenberg and his colleagues want to investigate whether this strategy is cost-effective so that the support of payers can also be ensured.
