The authors of a recent study published in the Annals of Internal Medicine estimate that physician burnout is costing this country’s health care system $4.6 billion annually, using a conservative base-case model (Ann Intern Med. 2019;170[11]:784-90). I guess we shouldn’t be surprised at the magnitude of the drain on our economy caused by unhappy physicians. We all know colleagues who are showing signs of burnout. And, you may be feeling yourself that the challenges of work are taking too great a toll on your physical and mental health? Would you be happier if you had more time?

A study reported in Harvard Business Review has looked at recent college graduates to determine if how they prioritize time and money can predict their future happiness (“Are New Graduates Happier Making More Money or Having More Time?” July 25, 2019). The researchers at the Harvard Business School surveyed 1,000 college students in the 2015 and 2016 classes of the University of British Columbia, Vancouver. The students were asked to match themselves with descriptions of fictitious individuals to determine whether in general they prioritized time or money. The researchers then assessed the students’ level of happiness by asking them, “How satisfied are you with life overall?”

At a 2-year follow-up, the researchers found that, even taking into account the students’ level of happiness at the beginning of the study, “those who prioritized time were happier.” The authors also found that time-oriented people don’t necessarily work less or even earn more money, prompting their conclusion there is “strong evidence that valuing time puts people on a trajectory toward job satisfaction and well-being.”

Do the results of this study of Canadian college students provide any answers for our epidemic of physician burnout? One could argue that, if we wanted to minimize burnout, medical schools should include an assessment of each applicant’s level of happiness and how she or he prioritizes time and money using methods similar those used in this study? The problem is that some students are so heavily committed to becoming physicians that they would game the system and provide answers that will project the image that they are happy and prioritize time over money, when in reality they are ticking time bombs of discontent.

The bigger problem with interpreting the results of this study is that the subjects were Canadians who have significantly less educational debt than the medical students in this country. And as the authors observe, “people with objective financial constraints ... are more likely to focus on having more money.” Even the happiest time-oriented student can succumb to burnout when faced with a ponderous debt. Until we solve the problem of the high cost of medical education the system will continue to select for physicians whose decisions are too heavily influenced by their educational debt.

Finally, it is important to consider that time-oriented individuals don’t always work less, rather they make decisions that make it more likely that they will pursue activities they find enjoyable. For example, accepting a higher-paying job that requires an additional 3 hours of commute each day lays the foundation for a life in which a large portion of one’s day is expended in an activity that few of us find enjoyable. Choosing a long commute is a personal decision. Spending nearly 2 hours each day tethered to an EHR system was not something most physicians anticipated when they were choosing a career.

Veterans Affairs Lung Cancer Or Stereotactic Radiotherapy (VALOR)

The standard of care for stage I non-small cell lung cancer has historically been surgical resection in patients who are medically fit to tolerate an operation. Recent data now suggests that stereotactic radiotherapy may be a suitable alternative. This includes the results from a pooled analysis of two incomplete phase III studies that reported a 15% overall survival advantage with stereotactic radiotherapy at 3 years. While these data are promising, the median follow-up period was short, the results underpowered, and the findings were in contradiction to multiple retrospective studies that demonstrate the outcomes with surgery are likely equal or superior. Therefore, the herein trial aims to evaluate these two treatments in a prospective randomized fashion with a goal to compare the overall survival beyond 5 years. It has been designed to enroll patients who have a long life-expectancy, and are fit enough to tolerate an anatomic pulmonary resection with intraoperative lymph node sampling.

Radiation Therapy Regimens in Treating Patients With Limited-Stage Small Cell Lung Cancer Receiving Cisplatin and Etoposide

Radiation therapy uses high-energy x-rays to kill tumor cells. Drugs used in chemotherapy, such as etoposide, carboplatin and cisplatin, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. It is not yet known which radiation therapy regimen is more effective when given together with chemotherapy in treating patients with limited-stage small cell lung cancer. This randomized phase III trial is comparing different chest radiation therapy regimens to see how well they work in treating patients with limited-stage small cell lung cancer.

Lung Cancer Screening Decisions (VA-LCSDecTool)

Veterans have a high risk of developing lung in comparison to general populations due to their older age and smoking history. Recent evidence indicates that lung cancer screening with low dose CT scan reduces lung cancer mortality among older heavy smokers. However, the rates of false positive findings are high, requiring further testing and evaluation. Preliminary studies report that while some Veterans are enthusiastic about screening, others are highly reluctant. Patient preferences should be considered as part of an informed decision making process for this emerging paradigm of lung cancer control. Effective methods for preference assessment among Veterans have not yet been developed, evaluated, and integrated into clinical practice. The specific aims of this study are to 1) elicit patient and provider stakeholder input to inform the development of a lung cancer screening decision tool, 2) develop a web based Lung Cancer Screening Decision Tool (LCSDecTool) that incorporates patient and provider input, and 3) evaluate the impact of the LCSDecTool compared to usual care on the decision process, clinical outcomes, and quality of life.

Recent evidence indicates that lung cancer screening with low dose CT scan reduces lung cancer mortality among older heavy smokers. However, the rates of false positive findings are high, requiring further testing and evaluation. Preliminary studies report that while some Veterans are enthusiastic about screening, others are highly reluctant. Patient preferences should be considered as part of an informed decision making process for this emerging paradigm of lung cancer control. Effective methods for preference assessment among Veterans have not yet been developed, evaluated, and integrated into clinical practice. The specific aims of this study are to 1) elicit patient and provider stakeholder input to inform the development of a lung cancer screening decision tool, 2) develop a web based Lung Cancer Screening Decision Tool (LCSDecTool) that incorporates patient and provider input, and 3) evaluate the impact of the LCSDecTool compared to usual care on the decision process, clinical outcomes, and quality of life.

American Indians and Alaska Natives (AI/AN) are often misidentified as other races in public health administrative records. In the Northwest, for instance, the Northwest Tribal Epidemiology Center (NTEC) has found that about 10% of AI/AN birth and death records and up to 60% of hospitalization records are misclassified.

Racial misclassification makes it difficult to accurately assess the health of Native people: The numbers affected by a disease may appear lower or higher than they actually are. It can muddle and misrepresent information in birth certificates, cancer registries, death certificates, emergency department records, hospitalization records, injury reports. Without accurate health data, says Lisa Neel, director of the Indian Health Service (IHS) Tribal Epidemiology Center Program, tribes cannot make informed decisions about how best to serve their people.

That is why the IHS and the Center recently signed an agreement supporting a new information-sharing project. The agreement will allow the IHS to provide the NTEC with a list of people who have received health services at IHS, tribal, and urban Indian health programs in the Portland Area. The list will include no information about patients’ medical histories and will not be shared outside the NTEC. The center will then compare the list with outside information sources, such as state cancer registries, to check for racial misclassification.

The NTEC is 1 of 13 national “EpiCenters” charged with collecting tribal health status data, evaluating data monitoring and delivery systems, and helping tribes identify local priorities for health care delivery and health education. NTEC serves the 43 federally recognized tribes in Idaho, Oregon, and Washington. The center is housed in the Northwest Portland Area Indian Health Board (NPAIHB), whose delegates, representing the member tribes, direct and oversee activities, including health promotion, disease prevention, training and technical assistance.

The IHS plans for this to be a pilot project, possibly pointing the way for other tribal EpiCenters to launch similar projects.

Postmenopausal women with a first-degree family history of diabetes (FHD) had higher bone mineral density (BMD) than did those without such a history, according to results of a study.

Lijuan Yang, MD, of First Affiliated Hospital of Wenzhou (China) Medical University and colleagues reported the results in Menopause. The cross-sectional study included 892 normoglycemic postmenopausal women, of whom 147 had a first-degree FHD; the mean age was 55 years among both those with and those without first-degree FHD. The investigators assessed BMDs of the femoral neck and lumbar spine with dual-energy x-ray absorptiometry and insulin resistance with Homeostasis Model Assessment of Insulin Resistance (HOMA-IR).

Lumbar spine BMD was higher in those with first-degree FHD than in those without, at 1.077 and 1.034 g/cm², respectively; femoral neck BMD was similarly higher at 0.89 vs. 0.85 g/cm², respectively. HOMA-IR also was higher among those with first-degree FHD than among those without, at 1.85 and 1.60, respectively.

Spearman’s correlation analyses showed that lumbar spine BMD was positively associated with first-degree FHD (P = .008) and HOMA-IR (P = .041), as was femoral neck BMD (P = .013 and P = .005, respectively). Results of multiple stepwise regression analysis showed that first-degree FHD and HOMA-IR were independent factors positively associated with femoral neck BMD (P = .029 and P = .0009, respectively) and lumbar spine BMD (P = .029 and P = .002).

“The present study demonstrated that lumbar spine BMD and femoral neck BMD were positively associated with HOMA-IR in postmenopausal women and that individuals with a first-degree FHD were more likely to have high HOMA-IR,” the investigators said. “We suggest that the elevated BMD in individuals with a first-degree FHD could be attributed to insulin resistance,” which appears to be inherited by persons with a first-degree FHD.

The authors noted that the cross-sectional design is a limitations of this study. They suggested future studies might investigate the relationship between insulin resistance and bone development in these populations by assessing osteocalcin and P1NP.

The study received funding or support from National Key R&D Program of China and from the Wenzhou Science & Technology Bureau. The authors did not disclose any conflicts of interest.

Parents who accepted, denied, or partially accepted participation in the Dutch National Immunization Program reached their decisions through different methods, according to Kim A.G.J. Romijnders of the National Institute for Public Health and the Environment in Bilthoven, the Netherlands, and associates.

For the study published in Vaccine, the investigators conducted a series of 12 focus groups: 3 with accepters (n = 19), 3 with deniers (n =12), and 6 with partial accepters (n =24); in the partial accepters groups, there were three groups with parents delaying vaccination and three with parents refusing some vaccinations. Three-quarters of participants were women, the average age was 39 years, and 96% had at least university education. Parents were asked about their knowledge, attitudes, deliberation, and information needs regarding childhood vaccination.

Vaccine accepters regarded the decision to vaccinate their children as self-evident, but deniers and partial accepters reported conducting extensive deliberation on the pros and cons of vaccination. Deniers and partial accepters, in general, perceived fewer risks of vaccine-preventable diseases, more risks of vaccine side effects, less social support from their environment, less trust in child welfare centers, and provided less information than accepters.

The investigators noted that vaccine deniers tended to rely on anecdotal evidence, while the deliberation that partial accepters undertook was both time consuming and difficult. This process alienated them from their child vaccine provider, with trust being lost when the provider either refused or was unable to answer questions. Partial accepters also reported a lack of social support from friends, family, and providers regarding partial vaccine acceptance.

“The findings can facilitate informed decision making among parents by promoting an open dialogue at the [child welfare center], and improving the type and form of information presented. An open dialogue between parents and [child vaccine providers] may increase deliberation among parents, strengthen positive attitudes, prevent misperceptions, and resolve decisional conflict,” the investigators concluded.

The study was supported by the Dutch National Institute for Public Health and the Environment; the authors reported no conflicts of interest.

The Food and Drug Administration has warned that certain hepatitis C virus medications have led to rare instances of worsening liver function or liver failure.

Many of the affected patients had signs or symptoms of moderate to severe liver impairment (Child-Pugh class B or C), and given that these medications – glecaprevir/pibrentasvir (Mavyret), elbasvir/grazoprevir (Zepatier), and sofosbuvir/velpatasvir/voxilaprevir (Vosevi) – are not indicated for such patients, they should not have been prescribed in the first place, the FDA noted in the drug safety communication. Some cases had other preexisting risk factors, such as liver cancer, alcohol abuse, or serious medical illnesses associated with liver problems.

In most cases, impairment or decompensation occurred within the first 4 weeks of starting treatment, and symptoms resolved or new-onset worsening of liver function improved after stopping. These medicines have been widely used and, among patients with no or mild liver impairment, have been shown to be safe and effective.

Health care professionals should continue prescribing these medicines as indicated; they should assess patients at baseline for severity of liver disease and other risk factors and closely monitor these patients after for signs and symptoms of worsening liver function. Patients should be aware that the risk of injury is rare and continue taking prescribed medicines; if they develop fatigue, weakness, loss of appetite, nausea and vomiting, yellow eyes or skin, or light-colored stools, they should talk with their health care professional but should continue taking the medications in question until instructed to do otherwise.

The full communication is available on the FDA website and includes more facts about these drugs and information for patients and health care professionals.

For young patients with high-risk neuroblastoma, an intensive consolidation regimen with tandem autologous stem cell transplants was associated with significantly better event-free survival, compared with single-transplant consolidation, results of a randomized trial show.

Among 355 patients with high-risk neuroblastoma, the 3-year event-free survival (EFS) rate was 61.6% for patients randomized to tandem (sequential) autologous stem cell transplants, compared with 48.4% for patients randomized to a single transplant (P = .006), reported Julie R. Park, MD from Seattle Children’s Hospital in Washington, and coinvestigators in the Children’s Oncology Group’s ANBL0532 trial.

“Results of the current study are consistent with earlier trials demonstrating that induction chemotherapy followed by consolidation with autologous transplant improved EFS, compared with less intensive consolidation, and that further intensification of consolidation benefits some patients,” they wrote in JAMA.

But of the 652 patients enrolled in the study, only 355 were actually randomized. Although the randomization rate was slightly higher than anticipated, the authors acknowledged that the results may not apply to all patients with high-risk neuroblastoma.

Patients eligible for the trial included those with International Neuroblastoma Staging System (INSS) stage 4 neuroblastoma aged older than 18 months; INSS stage 3 neuroblastoma aged older than 18 months with International Neuroblastoma Pathology Classification of unfavorable histology; INSS stage 2, 3, 4, or 4S neuroblastoma with MYCN amplification; and INSS stage 4 neuroblastoma diagnosed from age 12-18 months whose tumors showed any unfavorable features. Patients initially diagnosed with non–high-risk neuroblastoma (including stage 1) who had not received chemotherapy and whose disease had progressed to high-risk neuroblastoma were also eligible.

Following induction with two cycles of topotecan and cyclophosphamide, patients underwent peripheral blood stem cell collection, followed by four alternating cycles of cisplatin and etoposide and doxorubicin and cyclophosphamide, and vincristine.

For those patients who did not have primary tumors resected at diagnosis, resection was performed after the fourth or fifth cycle.

Those patients who after induction had no disease progression, no uncontrolled infection, sufficient stem cell levels, and adequate organ function were then eligible for randomization. One patient did not receive any therapy, 27 were nonrandomly assigned to single transplant, 62 were not eligible for randomization, and 207 were not randomized because of physician or family preference.

Of the remaining patients (median age at diagnosis, 36.1 months) 176 were randomized to receive tandem transplant with thiotepa and cyclophosphamide followed by dose-reduced carboplatin, etoposide, and melphalan conditioning, and 179 were randomized to single transplant with standard-dose carboplatin, etoposide, and melphalan.

A total of 17 patients died on study from toxicity; 7 during induction and 10 during consolidation. Significant transplant-related toxicities included mucositis in 11.7% of tandem-transplant patients and 15.4% of single-transplant patients, and infections in 17.8% versus 18.3%, respectively.

As noted before, 3-year EFS from the time of randomization, the primary endpoint, was higher for patients in the tandem-transplant arm (61.6% vs. 48.4%, P = .006).

The median duration of follow-up after randomization for patients without relapse, disease progression, second malignancy, or death was 5.6 years.

A post hoc analysis of the randomized patients showed a 3-year overall survival rate of 71.6%, which did not differ significantly between the study arms (74.1% for the tandem-transplant group vs. 68.1% for the single-transplant group). The analysis also showed that 3-year EFS and overall survival was higher in the tandem- versus single-transplant groups among 250 patients who also received immunotherapy with isotretinoin plus an anti-GD2 chimeric antibody and cytokines.

The trial was supported by grants from the National Institutes of Health, National Cancer Institute, National Clinical Trials Network Operations Center, and St. Baldrick’s Foundation.

For young patients with high-risk neuroblastoma, an intensive consolidation regimen with tandem autologous stem cell transplants was associated with significantly better event-free survival, compared with single-transplant consolidation, results of a randomized trial show.

Among 355 patients with high-risk neuroblastoma, the 3-year event-free survival (EFS) rate was 61.6% for patients randomized to tandem (sequential) autologous stem cell transplants, compared with 48.4% for patients randomized to a single transplant (P = .006), reported Julie R. Park, MD from Seattle Children’s Hospital in Washington, and coinvestigators in the Children’s Oncology Group’s ANBL0532 trial.

“Results of the current study are consistent with earlier trials demonstrating that induction chemotherapy followed by consolidation with autologous transplant improved EFS, compared with less intensive consolidation, and that further intensification of consolidation benefits some patients,” they wrote in JAMA.

But of the 652 patients enrolled in the study, only 355 were actually randomized. Although the randomization rate was slightly higher than anticipated, the authors acknowledged that the results may not apply to all patients with high-risk neuroblastoma.

Patients eligible for the trial included those with International Neuroblastoma Staging System (INSS) stage 4 neuroblastoma aged older than 18 months; INSS stage 3 neuroblastoma aged older than 18 months with International Neuroblastoma Pathology Classification of unfavorable histology; INSS stage 2, 3, 4, or 4S neuroblastoma with MYCN amplification; and INSS stage 4 neuroblastoma diagnosed from age 12-18 months whose tumors showed any unfavorable features. Patients initially diagnosed with non–high-risk neuroblastoma (including stage 1) who had not received chemotherapy and whose disease had progressed to high-risk neuroblastoma were also eligible.

Following induction with two cycles of topotecan and cyclophosphamide, patients underwent peripheral blood stem cell collection, followed by four alternating cycles of cisplatin and etoposide and doxorubicin and cyclophosphamide, and vincristine.

For those patients who did not have primary tumors resected at diagnosis, resection was performed after the fourth or fifth cycle.

Those patients who after induction had no disease progression, no uncontrolled infection, sufficient stem cell levels, and adequate organ function were then eligible for randomization. One patient did not receive any therapy, 27 were nonrandomly assigned to single transplant, 62 were not eligible for randomization, and 207 were not randomized because of physician or family preference.

Of the remaining patients (median age at diagnosis, 36.1 months) 176 were randomized to receive tandem transplant with thiotepa and cyclophosphamide followed by dose-reduced carboplatin, etoposide, and melphalan conditioning, and 179 were randomized to single transplant with standard-dose carboplatin, etoposide, and melphalan.

A total of 17 patients died on study from toxicity; 7 during induction and 10 during consolidation. Significant transplant-related toxicities included mucositis in 11.7% of tandem-transplant patients and 15.4% of single-transplant patients, and infections in 17.8% versus 18.3%, respectively.

As noted before, 3-year EFS from the time of randomization, the primary endpoint, was higher for patients in the tandem-transplant arm (61.6% vs. 48.4%, P = .006).

There is no single “gay gene.”

There are, however, signals that nonheterosexual behavior has at least some genetic component, according to Andrea Ganna, PhD, and colleagues.

Five candidate genes found in a half-million subject genetic study each account for less than 1% of the variance in same-sex sexual behavior, the scientists found. Over the entire genome, genetic variants accounted for less than a quarter of such behavior.

None of the genetic signals can reliably predict sexual behavior, Benjamin Neale, PhD, director of genetics in the Stanley Center for Psychiatric Research at the Broad Institute of the Massachusetts Institute of Technology and Harvard Medical School, both in Boston, said in a telebriefing that included Dr. Ganna, a postdoctoral researcher in his lab. Instead, the variability of human sexuality is an entirely natural continuum of human behavior.

“Whether we are attracted exclusively to the opposite sex, the same sex, or both sexes falls along a spectrum that is an integral, and entirely normal, part of the human experience,” said Dr. Neale. “The choice of a sexual partner and the fraction of partners that are of the same sex are all consistent with this diversity being a key feature of our sexual behavior as a species and this diversity is a natural part of being human.”

The study, published in Science, clarifies findings of smaller, previous studies, which determined that sexual behavior is a combination of genetics and environment – although environment is a much more difficult association to assess.

“[Environment] can range from anything in utero, all the way all the way through who you happen to stand next to on the tube in the morning, right? That’s all potentially environmental factors that can have some influence on complex traits and so we don’t really understand,” Dr. Neale said.

However, he added, the concept of individual choice in sexual behaviors was beyond the scope of the study, which strictly centered on genetic associations with sexual behavior.

The study combined genetic information from three extant databases (the U.K. Biobank, National Longitudinal Study of Adolescent to Adult Health, the Molecular Genetic Study of Sexual Orientation, and the Child and Adolescent Twin Study in Sweden) with newly collected data from 23andMe, the technology company that provides at-home genetics tests largely used to determine ethnic origin.

The primary phenotype investigated was a binary measure: self-reported sexual behavior with someone of the same sex (nonheterosexuality) or someone of the opposite sex (heterosexuality).

“The binary variable also collapses rich and multifaceted diversity among nonheterosexuality individuals, wrote Dr. Ganna and his coauthors. Therefore, “we explored finer-scaled measurements and some of the complexities of the phenotype, although intricacies of the social and cultural influences on sexuality made it impossible to fully explore this complexity.”

The team also performed replication analyses on three smaller datasets: the Molecular Genetic Study of Sexual Orientation (2,308 U.S. adult males), Add Health (4,755 U.S. young adults), and the Child and Adolescent Twin Study in Sweden (8,093 Swedish adolescents). Data were available for 188,825 males and 220,170 females overall. When broken down by sexual behavior, data were available for 1,766 homosexual and 180,431 heterosexual males, and 693 homosexual and 214,062 heterosexual females.

The team identified two genes that significantly predicted same-sex sexual behavior (rs11114975-12q21.31 and rs10261857-7q31.2). Two more genes predicted same-sex sexual behavior in males only (rs28371400-15q21.3 and rs34730029-11q12.1), and one additional gene predicted the behavior in females only (rs13135637-4p14).

Three of the single nucleotide polymorphisms (SNPs) nominally replicated those in some of the other datasets, despite the much smaller sample sizes.

“The SNPs that reached genome-wide significance had very small effects (odds ratio, 1.1),” the authors wrote. “For example, in the U.K. Biobank, males with a GT genotype at the rs34730029 locus had 0.4% higher prevalence of same-sex sexual behavior than those with a TT genotype. Nevertheless, the contribution of all measured common SNPs in aggregate was estimated to [account for] 8%-25% of variation in female and male same-sex sexual behavior. … The discrepancy between the variance captured by the significant SNPs and all common SNPs suggests that same-sex sexual behavior, like most complex human traits, is influenced by the small, additive effects of very many genetic variants, most of which cannot be detected at the current sample size.”

The Child and Adolescent Twin Study in Sweden contained the youngest subjects. The polygenic scores in this dataset were significantly associated with sexual attraction at age 15 years, “suggesting that at least some of the genetic influences on same-sex sexual behavior manifest early in sexual development.”

The team also investigated the biological pathways associated with the SNPs. Among the male variants, rs34730029-11q12.1 contains numerous olfactory receptor genes.

“Second, rs28371400-15q21.3 had several indications of being involved in sex hormone regulation. The allele positively associated with same-sex sexual behavior is associated with higher rate of male pattern balding, in which sex-hormone sensitivity is implicated,” they wrote.

This is located near the TCF12 gene, related to a normal gonadal development in mice.

Among women, there were inverse associations with the level of sex hormone–binding globulin, which regulates the balance between testosterone and estrogen.

There were significant associations with some mental health traits, including loneliness, openness to experience, and risky behaviors such as smoking and using cannabis. There were also associations with depression and schizophrenia. The genetic correlations for bipolar disorder, cannabis use, and number of sexual partners were significantly higher in females than in males.

“We emphasize that the causal processes underlying these genetic correlations are unclear and could be generated by environmental factors relating to prejudice against individuals engaging in same-sex sexual behavior,” the authors wrote.

In an interview, Jack Drescher, MD, said he was not surprised by the findings and cited the results a twin study by J. Michael Bailey, PhD, and Richard C. Pillard, MD, as evidence of the complexities surrounding sexual orientation. The study examined the likelihood of one twin having a gay twin (Arch Gen Psychiatry. 1991 Dec;48[12]:1089-96).

“If you were a gay identical twin, you had a 52% chance of having a gay twin, he said. “If you were a gay fraternal twin, you only had a 22% chance of having a gay twin. The chance of an adoptive brother being gay was 11%. If homosexuality were simply a result of simple genetic transmission, then one would expect closer to 100% gay identical twins, since they both have the same genes.”

Dr. Drescher, clinical professor of psychiatry at the Center for Psychoanalytic Training and Research at Columbia University, New York, has written extensively about human sexuality, gender-conversion therapies, and gender.

The study by Dr. Ganna and associates as a whole invalidates several commonly used sexual behavior scales, including the Kinsey Scale, which is solely predicated upon self-reported attraction. The Klein Sexual Orientation Grid, which measures sexual behavior, fantasies, and sexual identification, is similarly problematic, the authors noted.

“Overall, our findings suggest that the most popular measures are based on a misconception of the underlying structure of sexual orientation and may need to be rethought. In particular, using separate measures of attraction to the opposite sex and attraction to the same sex, such as in the Sell Assessment of Sexual Orientation, would remove the assumption that these variables are perfectly inversely related and would enable more nuanced exploration of the full diversity of sexual orientation, including bisexuality and asexuality,” they wrote.

During the telebriefing discussion, Dr. Neale said the study supports the nuances in sexuality espoused by self-identified sexual orientation communities. “I think those things that we’ve learned include the idea that there is more diversity out there in the world. We see that diversity in the genetic analysis. And we reinforce that sort of message that the expanding acronyms in the LGBTQIA+ [lesbian, gay, bisexual, transgender, queer, intersex, asexual, and other] is justified.”

The study “underscores that there is an element of biology and it underscores that there’s an element of the environment,” he said. “And it underscores that this is a natural part of our species and so these are the things that both matter and there’s no way to get away from that idea.”

Several entities funded the study, including the Eunice Kennedy Shriver National Institute of Child Health and Human Development. Dr. Ganna reported no financial conflicts. Two of the researchers and members of the 23andMe research team are 23andMe employees or hold stock options in the company. Another researcher is affiliated with Deep Genomics as a member of its scientific advisory board.

Dr. Drescher, clinical professor of psychiatry at the Center for Psychoanalytic Training and Research at Columbia University, New York, has written extensively about human sexuality, gender-conversion therapies, and gender.

The study by Dr. Ganna and associates as a whole invalidates several commonly used sexual behavior scales, including the Kinsey Scale, which is solely predicated upon self-reported attraction. The Klein Sexual Orientation Grid, which measures sexual behavior, fantasies, and sexual identification, is similarly problematic, the authors noted.

“Overall, our findings suggest that the most popular measures are based on a misconception of the underlying structure of sexual orientation and may need to be rethought. In particular, using separate measures of attraction to the opposite sex and attraction to the same sex, such as in the Sell Assessment of Sexual Orientation, would remove the assumption that these variables are perfectly inversely related and would enable more nuanced exploration of the full diversity of sexual orientation, including bisexuality and asexuality,” they wrote.

During the telebriefing discussion, Dr. Neale said the study supports the nuances in sexuality espoused by self-identified sexual orientation communities. “I think those things that we’ve learned include the idea that there is more diversity out there in the world. We see that diversity in the genetic analysis. And we reinforce that sort of message that the expanding acronyms in the LGBTQIA+ [lesbian, gay, bisexual, transgender, queer, intersex, asexual, and other] is justified.”

The study “underscores that there is an element of biology and it underscores that there’s an element of the environment,” he said. “And it underscores that this is a natural part of our species and so these are the things that both matter and there’s no way to get away from that idea.”

Several entities funded the study, including the Eunice Kennedy Shriver National Institute of Child Health and Human Development. Dr. Ganna reported no financial conflicts. Two of the researchers and members of the 23andMe research team are 23andMe employees or hold stock options in the company. Another researcher is affiliated with Deep Genomics as a member of its scientific advisory board.

Administering an HIV drug concurrently with chemoradiotherapy resulted in promising local control and overall survival in patients with unresectable, locally advanced non–small cell lung cancer, researchers reported.

There was no overt exacerbation of the toxic effects of chemoradiotherapy with the addition of nelfinavir, a protease inhibitor, in the prospective, open-label, phase 1/2 study, the researchers wrote.

Nelfinavir plus chemoradiotherapy yielded a median progression-free survival of 11.7 months and median survival of 41.1 months, while the cumulative local failure incidence was 39% according to their report.

Those outcomes compare favorably with historical data, the investigators wrote in JAMA Oncology.

In benchmark results of the RTOG 0617 study of chemoradiotherapy in locally advanced non–small cell lung cancer, median overall survival was 28.7 months receiving radiotherapy at a standard dose of 60 Gy, and 20.3 months for those receiving high-dose (74 Gy) radiotherapy.

However, a randomized, phase 3 trial is needed to confirm these latest results with a protease inhibitor added to chemotherapy, according to Ramesh Rengan, MD, PhD, of the University of Washington, Seattle, and coinvestigators.

“As nelfinavir is a U.S. Food and Drug Administration–approved oral drug, this treatment approach is feasible and is potentially a readily exportable platform for daily clinical use,” Dr. Rengan and coauthors wrote.

In vitro and in vivo studies have shown that nelfinavir inhibited PI3K and Akt signaling, sensitized tumor cells to ionizing radiation, and improved tumor perfusion in animal models. “We hypothesize that it is these properties that drive the clinical results observed in this study,” Dr. Rengan and coauthors wrote.

They reported on a total of 35 patients with stage IIIA/IIIB non–small cell lung cancer who received nelfinavir at either 625 mg or 1,250 mg twice daily, starting 7-14 days before starting radiotherapy to 66.6 Gy at 1.8 Gy per fraction, and throughout the full course of radiotherapy.

There were no dose-limiting toxic effects observed in the study, and toxic effects were “acceptable,” with no grade 4 nonhematologic toxic effects seen, according to investigators. Leukopenia was the primary grade 3-4 hematologic toxic effect, observed in 2 of 5 patients receiving the lower nelfinavir dose and 18 of 30 at the higher dose.

Beyond non–small cell lung cancer, the efficacy and safety nelfinavir given concurrently with radiotherapy has been looked at in other disease settings. Data from those trials suggest that this protease inhibitor could “augment tumor response” not only in non–small cell lung cancer, but in locally advanced pancreatic cancer and glioblastoma, all of which are relatively radioresistant, according to Dr. Rengan and colleagues.

Study support came from grants from the National Institutes of Health and Abramson Cancer Center, and an American Society for Radiation Oncology training award to Dr. Rengan. Study authors reported disclosures related to Pfizer, 511 Pharma, Progenics Pharmaceuticals, Siemens, Actinium, AstraZeneca, Merck, Bristol-Myers Squibb, and others.
