Nivolumab has “limited intracranial activity” in patients with clear cell renal cell carcinoma (ccRCC) and previously untreated brain metastases, according to researchers.

In a phase 2 trial, nivolumab produced an intracranial response rate of 12% in ccRCC patients with previously untreated brain metastases.

The median intracranial progression-free survival (PFS) was longer among patients who had received prior focal therapy than among those with previously untreated brain metastases.

These results suggest “brain imaging and focal therapy should be considered before immune checkpoint inhibitors in patients with metastatic ccRCC,” Ronan Flippot, MD, of Université Paris-Saclay in Villejuif, France, and colleagues wrote in the Journal of Clinical Oncology.

Dr. Flippot and colleagues conducted this analysis of patients from the phase 2 GETUG-AFU 26 NIVOREN trial (NCT03013335). The researchers looked at 73 ccRCC patients with asymptomatic brain metastases who had received at least one prior line of antiangiogenic treatment.

Patients were divided into two cohorts. Cohort A included patients with previously untreated brain metastases (n = 39), and cohort B included patients who had received focal therapy for brain metastases (n = 34).

Baseline characteristics were similar between the cohorts. The median ages were 61 years in cohort A (range, 39-77) and 58 years in cohort B (range, 33-78). Most patients had grade 3-4 tumors (64% in cohort A and 78% in cohort B), and most had one brain lesion (67% and 59%, respectively). The median sum of the diameters of target lesions was 11 mm in cohort A and 17 mm in cohort B.

All patients received intravenous nivolumab at 3 mg/kg every 2 weeks until they progressed, developed unacceptable toxicity, died, withdrew consent, or the investigator stopped treatment.

The median follow-up was 23.6 months in cohort A and 20.2 months in cohort B. The median duration of treatment was 4.9 months and 4.5 months, respectively. Five patients in cohort A and four in cohort B were still receiving nivolumab at the data cutoff.

Response

The primary endpoint was the intracranial response rate in cohort A, which was 12%. All four responders achieved a complete response. At baseline, all of them had grade 1-2 disease and a single brain lesion smaller than 1 cm.

Thirteen patients (38%) in cohort A had stable intracranial disease as their best response, and 17 (50%) had progressive intracranial disease. The remaining five patients could not be evaluated because they progressed and died before the first evaluation.

The extracranial response rate in cohort A was 21%, and all seven responders had partial responses. Ten patients had stable extracranial disease (30%), and 16 had extracranial progression (49%). The remaining six patients were not evaluable for extracranial response.

All four patients who achieved a complete intracranial response had a partial extracranial response. Six patients (18%) had discordant intracranial and extracranial responses.
 

Survival

The median intracranial PFS in cohort A was 2.7 months in cohort A versus 4.8 months in cohort B. When the researchers adjusted for baseline characteristics, they found that prior focal therapy decreased the risk of intracranial progression (hazard ratio, 0.49).

The median extracranial PFS was 2.8 months in cohort A versus 2.6 months in cohort B. The median global PFS was 2.4 months in cohort A versus 2.5 months in cohort B.

The overall survival rates at 12 months were 66.7% in cohort A and 58.8% in cohort B.

Safety

The most common treatment-related adverse events (in cohort A and B, respectively) were asthenia (21% and 24%) and rash (10% and 9%).

Grade 3/4 treatment-related adverse events occurred in four patients in cohort A and five in cohort B. In cohort A, these events were asthenia, elevated liver function tests, dyspnea, and atrioventricular block. In cohort B, the events were diarrhea, musculoskeletal pain, psoriasis, hypophosphatemia, and elevated creatinine (in two patients).

The patient who developed atrioventricular block permanently discontinued nivolumab. There were no other treatment-related adverse events that led to discontinuation.

This study was supported by Bristol-Myers Squibb. The researchers disclosed relationships with Bristol-Myers Squibb and many other companies.

Novel extended half-life factor VIII (FVIII) and factor IX (FIX) products appear to decrease the number of infusions and maintain higher trough levels, especially for patients with hemophilia B, according to recent survey findings.

Preliminary data from a European multinational survey suggest these benefits may help overcome current limitations with standard clotting factor products.

“We administered a survey to determine the efficacy of [extended half-life] products after they became available in several European countries,” wrote Flora Peyvandi, MD, PhD, of Fondazione IRCCS Ca’ Granda Ospedale Maggiore Policlinico in Milan and colleagues. These results were published in Haemophilia.

The questionnaire, designed by the European Association for Haemophilia and Allied Disorders (EAHAD), was distributed to 48 hemophilia treatment centers in January 2018. In total, 33 centers completed the survey.

The survey explored the real-life clinical experiences of patients with hemophilia A and B using extended half-life FVIII and FIX products. At the time of the survey, pegylated factor products were not available for use. In particular, the survey collected general information related to the efficacy of prophylaxis after transitioning patients to novel extended half-life products.

After analysis, the researchers found that among responding centers, extended half-life FVIII products decreased the number of infusions by 30% or greater among hemophilia A patients and achieved trough levels of 3%-5% in 66%-67% of centers.

With respect to FIX products, all responding centers were able to reduce infusions by more than 30% among hemophilia B patients, with 67% maintaining a FIX trough level of no less than 5%-10%.

The researchers acknowledged that the findings are preliminary and should be confirmed by conducting a repeat survey.

“Evaluating the safety of these new drugs is of the utmost importance and should be monitored through careful, long‐term observation,” they concluded.

No funding sources were reported. The authors reported financial affiliations with Alnylam, Grifols, Kedrion, Pfizer, Roche, Sanofi, Bayer, Shire, and several other companies.

BANGKOK – Investigators at University College London have identified what appears to be an important mechanism underlying the efficacy of ketogenic diet therapy for seizure reduction in patients with drug-refractory epilepsy, then used that insight to develop a medium-chain triglyceride–based drink designed to address the well-known shortcomings of standard ketogenic diets.

Chief among those shortcomings is the notoriously poor compliance with these highly restrictive diets, which, as defining features, emphasize high fat intake and scrupulous restriction of carbohydrates in an effort to mimic the metabolic effects of starvation, J. Helen Cross, MD, explained at the International Epilepsy Congress.

She was a coauthor of a study led by Natasha E. Schoeler, PhD, a research dietician at the University College London Great Ormond Street Institute of Child Health, which demonstrated that children and adults with epilepsy who experience a significant antiseizure effect in response to ketogenic diet therapies have higher baseline blood levels of acetyl carnitine (Epilepsia. 2017 May;58(5):893-900).

The importance of this novel observation is twofold: It indicates a potential role for baseline acetyl carnitine level as a predictor of differential response to ketogenic diet therapies, a predictor for which there is an unmet need, and it is consistent with the hypothesis that an important potential mechanism of ketogenic diet effectiveness in epilepsy involves altered mitochondrial energy metabolism. That is because acetyl carnitine plays an essential role in mitochondrial uptake of long-chain fatty acids, noted Dr. Cross, professor of pediatric neurology and head of the developmental neurosciences program at the University College London Great Ormond Street Institute of Child Health.

At the congress sponsored by the International League Against Epilepsy, Dr. Cross and Dr. Schoeler presented the results of the initial 12-week tolerability study of Betashot, a ready-to-use, palatable blend of specific medium-chain triglycerides designed to be consumed three to four times daily with normal meals, limiting only intake of foods high in refined sugar. The Betashot beverage was developed in conjunction with Vitaflo International, a nutritional products company.

“It actually tastes good. It tastes like a strawberry shake,” according to Dr. Schoeler.

The 12-week study included 35 children with genetically caused forms of epilepsy and 26 adults with drug-resistant epilepsy. This was primarily a tolerability and compliance study, and the main finding was that two-thirds of the children and 69% of adults who started the study were still using Betashot at the 12-week mark. Moreover, 91% of the children and 56% of adults who completed the study elected to stay on Betashot afterwards. By week 12, after titrating their daily dose of Betashot upward as tolerated, the pediatric patients averaged 18% of their total daily energy intake from Betashot, the adults 24%.

The most common reasons for discontinuation among both children and adults were gastrointestinal side effects: abdominal discomfort, diarrhea, and/or vomiting.

“What’s exciting is that, even though the study is not powered to look at seizure response – it’s a tolerability study – we can report that there was a statistically significant reduction in the number of seizures in the group overall after 3 months of treatment,” Dr. Cross said.

She declined to provide specific data on seizure frequency because the study was underpowered for that endpoint. However, she added that further larger studies looking at a possible antiseizure effect of Betashot are ongoing.

The Betashot study was funded by Vitaflo International.

Combination quercetin and desferrioxamine could decrease iron overload in patients with transfusion-dependent beta-thalassemia major, according to a randomized clinical study.

Over the course of treatment, quercetin was well tolerated and no major complications were reported. The findings highlight the potential of quercetin to lower ferritin levels in patients with thalassemia major.

“Quercetin is a member of flavone family that mainly exists in apples, onions, tea, red wines, and berries,” wrote Zohreh Sajadi Hezaveh of Iran University of Medical Sciences in Tehran and colleagues. The findings of the study were published in Complementary Therapies in Medicine.

The researchers conducted a randomized, double-blind trial of 84 patients with thalassemia major. Of those enrolled, 71 patients were included in the final analysis.

Study patients were randomly assigned to receive either oral quercetin 500 mg daily or placebo for a total of 12 weeks. At baseline, all patients received desferrioxamine monotherapy. All participants were enrolled in the single-center study from April 2017 to March 2018. The team measured several inflammatory and iron-related markers during the study.

In comparison with placebo, combined therapy significantly improved high sensitivity C-reactive protein (P = .046), ferritin (P = .043), serum iron (P = .036), transferrin (P = .045), and transferrin saturation (P = .008), but not tumor necrosis factor–alpha (P = .310) or total iron-binding capacity (P = .734).

With respect to ferritin levels, a significant decrease was observed in the quercetin group, while patients in the placebo group had a marginal increase in levels.

“Insignificant results for [tumor necrosis factor–alpha] prevents us from making definitive comments [about inflammation],” the researchers wrote.

One key limitation of the study was the significant loss to follow-up seen in the placebo group. As a result, the generalizability of the findings may be limited.

“These results need to be confirmed by studies with larger sample size, longer follow-up period, and different doses of quercetin,” the researchers concluded.

The study was funded by the Iran University of Medical Sciences. The authors reported having no conflicts of interest.

Combination quercetin and desferrioxamine could decrease iron overload in patients with transfusion-dependent beta-thalassemia major, according to a randomized clinical study.

Over the course of treatment, quercetin was well tolerated and no major complications were reported. The findings highlight the potential of quercetin to lower ferritin levels in patients with thalassemia major.

“Quercetin is a member of flavone family that mainly exists in apples, onions, tea, red wines, and berries,” wrote Zohreh Sajadi Hezaveh of Iran University of Medical Sciences in Tehran and colleagues. The findings of the study were published in Complementary Therapies in Medicine.

The researchers conducted a randomized, double-blind trial of 84 patients with thalassemia major. Of those enrolled, 71 patients were included in the final analysis.

Study patients were randomly assigned to receive either oral quercetin 500 mg daily or placebo for a total of 12 weeks. At baseline, all patients received desferrioxamine monotherapy. All participants were enrolled in the single-center study from April 2017 to March 2018. The team measured several inflammatory and iron-related markers during the study.

In comparison with placebo, combined therapy significantly improved high sensitivity C-reactive protein (P = .046), ferritin (P = .043), serum iron (P = .036), transferrin (P = .045), and transferrin saturation (P = .008), but not tumor necrosis factor–alpha (P = .310) or total iron-binding capacity (P = .734).

With respect to ferritin levels, a significant decrease was observed in the quercetin group, while patients in the placebo group had a marginal increase in levels.

“Insignificant results for [tumor necrosis factor–alpha] prevents us from making definitive comments [about inflammation],” the researchers wrote.

One key limitation of the study was the significant loss to follow-up seen in the placebo group. As a result, the generalizability of the findings may be limited.

“These results need to be confirmed by studies with larger sample size, longer follow-up period, and different doses of quercetin,” the researchers concluded.

The study was funded by the Iran University of Medical Sciences. The authors reported having no conflicts of interest.

SEATTLE – If your hospital’s methicillin-resistant Staphylococcus aureus rate is less than 10%, cefazolin is a reasonable empiric choice for pediatric acute hematogenous osteomyelitis (AHO). It covers the usual suspects: methicillin-susceptible Staphylococcus aureus, group A Streptococcus, and Kingella.

Above the 10% mark, coverage should include considerations of MRSA; clindamycin is good option so long as 85% of isolates are susceptible. Above that, it’s time for vancomycin, according to Nivedita Srinivas, MD, a pediatric infectious disease specialist at Stanford (Calif.) University.

There are no practice guidelines in the United States for the diagnosis and management of AHO in children; Dr. Srinivas and colleagues sought to plug the gaps in a talk at Pediatric Hospitalist Medicine.

Pediatric AHO is more common in children under 5 years old and in boys. Lower extremities are the usual targets. Staphylococcus aureus, group B Streptococcus, and gram negatives are the most common causes in newborns; Staphylococcus aureus, group A Streptococcus, and Kingella in older infants and preschoolers; and Staphylococcus aureus and group A Streptococcus in older children.

About half the time, treatment remains empiric because nothing grows out on culture, and there are a few clinical pearls to keep in mind in those cases. A family history of boils or spider bites is suspicious for MRSA, and coverage should include Salmonella in children with abnormal hemoglobins and Streptococcus pneumoniae in children without a spleen or with functional asplenia. Pseudomonas has to be kept in mind with puncture wounds, and Brucella in children who drink unpasteurized milk, Dr. Srinivas said.

A switch from IV to oral therapy is appropriate when C-reactive protein (CRP) drops 50% from its peak or below 3 mg/dL, positive cultures – if any – turn negative, fever has been absent for 24 hours, there’s no sign of metastatic disease, and patients have markedly reduced pain and can bear weight on the infected limb, said copresenter Marie Wang, MD, also a pediatric infectious disease specialist at Stanford.

The oral switch, of course, must have similar coverage as the IV antibiotic: high-dose cephalexin for cefazolin, for instance. Children can be sent home on a PICC line to continue IV treatment, but they won’t do any better than children switched to an oral treatment, and the indwelling catheter can cause problems, she said.

Pleuritic or other sudden pain at a distant site suggests septic emboli. “[Staphylococcus aureus] is notorious for going places you don’t” expect it to go “and forming microabscesses, which become larger abscesses” and need to be drained, said the third presenter, Russell McCulloh, MD, a pediatric infectious disease specialist at the University of Nebraska Medical Center, Omaha.

Four weeks of antibiotics are usually enough, so long as there aren’t complications such as septic thrombophlebitis, endocarditis, sickle cell disease, skull involvement, or immunodeficiencies. Source control and good, postdischarge care – including regular CRP and antibiotic toxicity labs – are critical. Monitoring is recommended for a year.

“X-rays are good at looking for longer-term complications, but bony abnormalities are not going to show up for the first 2 weeks,” Dr. McCulloh said.

The presenters didn’t have any relevant disclosures. The meeting was sponsored by the Society of Hospital Medicine, the American Academy of Pediatrics, and the Academic Pediatric Association.

Zoledronic acid was effective at preventing symptomatic periodontal disease in patients with osteoporosis and good oral hygiene, according to Akira Taguchi, DDS, PhD, of the department of oral and maxillofacial radiology at Matsumoto Dental University, Nagano, Japan, and associates.

bernardbodo/iStock/Getty Images Plus

In a study published in Menopause, the investigators retrospectively analyzed 542 men and women with osteoporosis who participated in the randomized ZONE (Zoledronate Treatment in Efficacy to Osteoporosis) trial. Patients received either zoledronic acid (n = 258) or placebo (n = 284) once yearly for 2 years by IV infusion; mean age was 74 years in both groups. Patients were instructed to maintain good oral health at baseline and every 3 months afterward. Participants with signs or symptoms involving the oral cavity at the follow-up approximately every 3 months were referred to dentists for examination of oral disease.

Oral adverse events were significantly more common in the placebo group, compared with the zoledronic acid group (20% vs. 14%; P = .04); incidence of symptomatic periodontal disease also was significantly more common in those receiving placebo (12% vs. 5%; P = .002). While loss of teeth was more common in the control group than in those receiving zoledronic acid (11% vs. 7%), the difference was not significant.

“Because zoledronic acid can prevent symptomatic periodontal disease when combined with good oral hygiene management, it is possible that the procedures performed in this study could eventually suppress the development of [osteonecrosis of the jaw],” the investigators concluded.

The study was funded by Asahi-Kasei Pharma. The investigators reported employment or receiving consulting fees from numerous pharmaceutical companies.

Cat ladies: They’re just like you and me

SilviaJansen/E+

Crazy cat ladies are … not so crazy after all. Bad news for stereotypes, but good news for women who love kitties.

A research team from UCLA observed over 500 pet owners to analyze how people reacted to distress calls from their pets. The investigators also looked at possible links between pet ownership and any mental health or social difficulties.

Pet owners were not significantly different from non–pet owners in rates of depression, anxiety, or interpersonal relationship functioning – meaning cat owners are scientifically proven to be normal.

The study authors specifically stated, “We found no evidence to support the ‘cat lady’ stereotype: cat-owners did not differ from others on self-reported symptoms of depression, anxiety or their experiences in close relationships.” Who would’ve thought?
 

Music is my hero

monkeybusinessimages/Thinkstock

If you’re feeling down and need a little more motivation in life, try putting in your headphones and listening to some Hans Zimmer scores. A recently published study found that “heroic” music stimulates motivating and empowering thoughts in listeners.

Researchers had participants listen to heroic and sad music samples and fill out questionnaires after listening. They found that listening to heroic music while the mind starts wandering promotes positive, constructive, and motivating thoughts.

No word yet, though, on whether any of the participants attempted to fly or save some kittens from a tree.

Intrauterine devices, pacemakers, insulin pumps, gastric bands, coronary stents, car keys: What do all of these things have in common? Right now, you’re probably thinking, “Well, I know what those first five have in common, but … car keys? There’s no way.” Yes way.

Aime Dansby, a software engineer from Dallas, had the key to her Tesla 3 – not the entire key, just the RFID chip from the credit-card-sized valet key – implanted into her arm by a body modification artist named “Pineapple,” according to Car & Driver. Seems she couldn’t get a physician to perform the procedure.

To make the chip “safe” for implantation, Ms. Dansby dissolved the rest of the card with acetone and then had the chip itself encased “in a biopolymer that is safe to use in the body and under the skin,” Popular Mechanics reported.

Ms. Dansby discusses some of her reasoning in a video on YouTube: “They say you can’t, like, start your car with that. It’s not secure. It won’t work. It makes me want to do it more.” We here at LOTME understand and support that kind of thinking, but we also hope that no one ever tells her she can’t start her car by sticking her finger in an electrical socket.

It can be difficult to get a precise estimate on the level of drug use within a city or country. Perhaps not surprisingly, many people aren’t entirely forthcoming about their drug habits, legal or not. But their poop … the poop never lies.

That’s why Stats Canada, in an effort to find new ways to collect data relating to the legalization of cannabis, conducted a survey of wastewater from five Canadian cities: Halifax, Montreal, Toronto, Edmonton, and Vancouver. In other words, they looked through the poop of about 8.4 million people to find out what drugs they preferred, gathering information on cannabis, cocaine, opioids, and methamphetamine.

Despite its legal status, cannabis usage was not uniform across the country, as Halifax and Montreal wastewater had THC levels more than twice as high as the other three cities. Stats Canada noted that Nova Scotia has higher-than-average cannabis usage, but Quebec as a whole has lower-than-average usage. Apparently the people of Montreal just really like their weed.

In fact, only cocaine showed no geographic bent. Opioids were significantly less popular in Toronto and Montreal, and methamphetamine was much more common in Edmonton and Vancouver.

In the end, Stats Canada concluded that wastewater analysis was an effective way to test drug usage, though we suspect they may have come to a different conclusion had they made anyone other than a bunch of polite Canadians sample the sewage of over 8 million people.

Pet owners were not significantly different from non–pet owners in rates of depression, anxiety, or interpersonal relationship functioning – meaning cat owners are scientifically proven to be normal.

The study authors specifically stated, “We found no evidence to support the ‘cat lady’ stereotype: cat-owners did not differ from others on self-reported symptoms of depression, anxiety or their experiences in close relationships.” Who would’ve thought?
 

Music is my hero

If you’re feeling down and need a little more motivation in life, try putting in your headphones and listening to some Hans Zimmer scores. A recently published study found that “heroic” music stimulates motivating and empowering thoughts in listeners.

Researchers had participants listen to heroic and sad music samples and fill out questionnaires after listening. They found that listening to heroic music while the mind starts wandering promotes positive, constructive, and motivating thoughts.

No word yet, though, on whether any of the participants attempted to fly or save some kittens from a tree.
 

The arms race continues

Intrauterine devices, pacemakers, insulin pumps, gastric bands, coronary stents, car keys: What do all of these things have in common? Right now, you’re probably thinking, “Well, I know what those first five have in common, but … car keys? There’s no way.” Yes way.

Aime Dansby, a software engineer from Dallas, had the key to her Tesla 3 – not the entire key, just the RFID chip from the credit-card-sized valet key – implanted into her arm by a body modification artist named “Pineapple,” according to Car & Driver. Seems she couldn’t get a physician to perform the procedure.

To make the chip “safe” for implantation, Ms. Dansby dissolved the rest of the card with acetone and then had the chip itself encased “in a biopolymer that is safe to use in the body and under the skin,” Popular Mechanics reported.

Ms. Dansby discusses some of her reasoning in a video on YouTube: “They say you can’t, like, start your car with that. It’s not secure. It won’t work. It makes me want to do it more.” We here at LOTME understand and support that kind of thinking, but we also hope that no one ever tells her she can’t start her car by sticking her finger in an electrical socket.


 

O (THC)anada

It can be difficult to get a precise estimate on the level of drug use within a city or country. Perhaps not surprisingly, many people aren’t entirely forthcoming about their drug habits, legal or not. But their poop … the poop never lies.

That’s why Stats Canada, in an effort to find new ways to collect data relating to the legalization of cannabis, conducted a survey of wastewater from five Canadian cities: Halifax, Montreal, Toronto, Edmonton, and Vancouver. In other words, they looked through the poop of about 8.4 million people to find out what drugs they preferred, gathering information on cannabis, cocaine, opioids, and methamphetamine.

Despite its legal status, cannabis usage was not uniform across the country, as Halifax and Montreal wastewater had THC levels more than twice as high as the other three cities. Stats Canada noted that Nova Scotia has higher-than-average cannabis usage, but Quebec as a whole has lower-than-average usage. Apparently the people of Montreal just really like their weed.

In fact, only cocaine showed no geographic bent. Opioids were significantly less popular in Toronto and Montreal, and methamphetamine was much more common in Edmonton and Vancouver.

In the end, Stats Canada concluded that wastewater analysis was an effective way to test drug usage, though we suspect they may have come to a different conclusion had they made anyone other than a bunch of polite Canadians sample the sewage of over 8 million people.
