Patients and doctors agree on treatment goals only half the time, according to JNCCN study on people with neuroendocrine tumors

Researchers from City of Hope find only 30% of people with neuroendocrine tumors consider living longer to be their single top priority; 70% said addressing and overcoming pain, fatigue, or lack-of-function was more important than just prolonging life.

PLYMOUTH MEETING, PA [December 12, 2022] — New research from cancer research and treatment organization City of Hope in the December 2022 issue of JNCCN—Journal of the National Comprehensive Cancer Network finds that only 30% of patients with advanced neuroendocrine tumors (NETs) say their top goal for treatment is living longer. The remaining patients selected other single specific treatment goals as most important, such as maintaining the ability to do daily activities, reducing or eliminating pain, or reducing or eliminating symptoms like fatigue. 66.7% of those surveyed agreed with the statement: “I would rather live a shorter life than lose my ability to take care of myself.”

However, respondents felt their doctors were more singularly focused on extending overall survival, even if it impacted other outcomes. Only 51.7% of patients perceived that they had the same treatment goals as their physician.

“As a result of this research, I think cancer care providers need to have more honest dialogue with all of their neuroendocrine tumor patients about treatment goals and priorities of various health outcomes from treatment,” said lead researcher Daneng Li, MD, Associate Professor in the Department of Medical Oncology & Therapeutics Research at City of Hope. “This finding really challenges the traditional dogma that patients just want to live longer. Discussions regarding treatment goals are essential to ensure that health care teams are truly respecting patients’ desires for what they would like to get out of their treatment and are incorporating those preferences into the selection of overall treatment choices and planning.”

The study was conducted with 60 patients with advanced NETs of gastrointestinal, pancreatic, thoracic, or unknown primary origin, who were starting a new line of systemic therapy between March 2019 and August 2020. In order to drill down on the impact of age, half of the patients were between 18 and 64-years-old, while the other half were 65-and-older. The patients’ feelings were tracked via four different survey methods ranking the importance of various outcomes and other preference-assessment tools.

Both younger and older patient groups ranked maintaining independence as the most valued outcome (46.7% for each), followed by survival (36.7% for younger, 23.3% for older), reducing or eliminating pain (16.7% and 6.7%), and reducing or eliminating dizziness, fatigue, and/or shortness of breath (0% and 23.3%).

“Patients with a cancer type that typically has a longer life expectancy often come to understand that the treatment journey is more of a marathon than a sprint. For these patients especially, the impact of treatment on how they feel on a day-to-day basis could impact their decision when choosing between various treatment options,” said Dr. Li. “Ultimately, the decision for a specific treatment is certainly individualized, and we hope that our study sheds light on the need for better communication between care providers and patients with neuroendocrine tumors in order to fully develop personalized treatment plans that are truly in line with the goals of each patient.”

“The study by Li, et. al. highlights the importance of considering the patient perspective when caring for patients with NETs,” agreed Emily Bergsland, MD, Professor of Medicine, UCSF Helen Diller Family Comprehensive Cancer Center, Director of the UCSF Center for Neuroendocrine Tumors, and Chair of the NCCN Guidelines® Panel for Neuroendocrine Tumors, who was not involved with this research. “Using validated surveys, the investigators found that adult patients with advanced NETs strongly value maintaining independence in daily activities over survival. Importantly, only about half of patients felt they shared the same primary treatment goal as their oncologist. The findings suggest a need for further research in this area, so we can better understand how to optimize patient-provider communication and ensure integration of patient preferences in treatment planning and medical decision-making.”

An ounce of prevention: Differences in HIV prevention activities among rural and urban physicians

Study shows family medicine physicians in rural areas are less comfortable providing sexual risk reduction counseling to adolescents than urban providers

Peer-Reviewed Publication

TEXAS A&M UNIVERSITY

HIV remains a major public health concern in the United States, with adolescents and young adults (15-24 years old) making up around 20 percent of new infections in the nation each year. Prevention is key to stopping HIV, and the U.S. Food and Drug Administration’s approval of HIV pre-exposure prophylaxis (PrEP) in recent years gave high-risk people a new and effective tool to protect their health.

PrEP is an HIV prevention medicine that must be prescribed by a provider but use among adolescents remains low. Most research into PrEP prescribing practices has focused on urban health care providers and their comfort in prescribing PrEP to adult patients. HIV infections are more prevalent in cities, but infection rates have been increasing in rural areas. At the same time, urban and rural youth engage in higher risk behaviors in roughly equal proportions. Despite this, there has been little focus on rural physician practices and attitudes toward PrEP, which could help improve HIV prevention efforts for rural youth.

In a new study, Christopher Owens, PhD, assistant professor at the Texas A&M University School of Public Health, analyzes factors related to PrEP prescribing comfort among rural and urban physicians in the United States. The study, published in The Journal of Rural Health, used data from a survey of 256 physicians to determine how aware physicians are of PrEP, their PrEP prescribing practices, and their comfort level in implementing PrEP clinical activities for adolescents.

Although both rural and urban physicians reported similar proportions of implementing PrEP clinical activities—such as sexual history taking, HIV testing and STI testing—rural physicians reported being less comfortable providing sexual risk reduction counseling to adolescents than urban providers

This study shows an increase in PrEP awareness from previous work and points to differences in comfort with PrEP-related activities between urban and rural providers that warrants further exploration. Future studies should look into how clinical resources, patient and provider demographics and other factors affect these outcomes.

This study and further research could help develop trainings and improvements to clinical resources, especially for physicians in rural communities where HIV infection rates are rising. HIV remains a significant health issue in both rural and urban communities, but it is important to increase rural physician’s comfort level in implementing PrEP-related clinical activities.

1. Low-carb diet may help patients with diabetes achieve better weight loss and glucose control in short term compared to a low-fat diet
Abstract: https://www.acpjournals.org/doi/10.7326/M22-1787

A randomized controlled trial of more than 100 persons with type 2 diabetes found that a low-carbohydrate, high-fat, calorie unrestricted diet helped patients achieve better weight loss and glucose control over a 6-month intervention compared to a high-carb, low-fat diet. The changes were not sustained 3 months after the intervention, suggesting a need for long-term dietary changes to maintain meaningful health benefits. The findings are published in Annals of Internal Medicine.

More than 480 million people worldwide are affected by type 2 diabetes. More than half of persons with diabetes also have nonalcoholic fatty liver disease (NAFLD), which can progress to cirrhosis and impair liver function. Prior studies suggest that weight loss improves both diabetes control and NAFLD and restriction of carbohydrate intake improves the control of blood sugar levels.

Researchers from the University of Southern Denmark, Odense, Denmark, randomly assigned 165 persons with type 2 diabetes to either a LCHF diet or a HCLF diet for 6 months. Participants in both groups were asked to eat the same number of calories equal to their energy expenditure. Participants on the low carb diet were asked to eat no more than 20% of their calories from carbohydrates but could have 50- 60% of their calories from fat and 20-30% from protein. Patients on the low-fat diet were asked to eat about half of their calories in carbohydrates and the rest evenly split between fats and proteins. The authors found that persons on the low carb diet reduced hemoglobin A1c by 0.59 percent more than the low-fat diet, and also lost 3.8 kg more weight compared to those in the low-fat group. The low carb dieters also lost more body fat and reduced their waist circumference. Both groups had higher high-density lipoprotein cholesterol and lower triglycerides at 6 months. However, changes were not sustained 3 months after the intervention, suggesting that dietary changes need to be sustained over the long term to maintain effects. The liver was not affected by the high fat intake in the low-carb group: The researchers found no difference on the amount of liver fat or inflammation between the two groups.

2. Nirmatrelvir plus ritonavir may reduce risk for hospitalization or death from COVID-19
Abstract: https://www.acpjournals.org/doi/10.7326/M22-2141
URL goes live when the embargo lifts
A retrospective cohort study of more than 44,000 nonhospitalized persons diagnosed with COVID-19 found that nirmatrelvir plus ritonavir reduced the overall risk of hospitalization and death. The study is published in Annals of Internal Medicine.

In the EPIC-HR (Evaluation of Protease Inhibition for Covid-19 in High-Risk Patients) trial, nirmatrelvir plus ritonavir led to an 89% reduction in hospitalization or death among unvaccinated outpatients with early COVID-19. The World Health Organization recommended nirmatrelvir plus ritonavir in April 2022, but only for the highest-risk persons and advised against use in most vaccinated and other lower-risk persons. The clinical impact of nirmatrelvir plus ritonavir among vaccinated populations is uncertain.

Researchers from Brigham and Women's Hospital and Harvard T.H. Chan School of Public Health studied 44,551 nonhospitalized persons with COVID-19 aged 50 years or older in the Mass General Brigham healthcare system to assess whether nirmatrelvir plus ritonavir could reduce the risk for hospitalization or death in the setting of prevalent SARS-CoV-2 immunity and immune-evasive SARS-CoV-2 lineages. More than 90% of participants had at least 3 vaccine doses at the time of the study. During the study period, 28.1% of participants received nirmatrelvir plus ritonavir and 71.9% did not. The authors found that recipients of nirmatrelvir plus ritonavir had 40% lower risk for hospitalization and 71% lower risk of death, although the risk for either was already very low (less than 1%). Overall, the mortality rate among persons prescribed nirmatrelvir plus ritonavir was 0.55% and 0.97% among persons who were not. The authors note that among those who were diagnosed as outpatients, Black, Hispanic, or Latinx patients had much lower rates of prescription of nirmatrelvir plus ritonavir. To realize the public health potential of outpatient COVID-19 therapy, clinicians must address this gap and these disparities.

3. Early engagement with affected communities helped to control mpox outbreak in Montreal
Abstract: https://www.acpjournals.org/doi/10.7326/M22-2699
URL goes live when the embargo lifts
An analysis of the first large mpox outbreak in North America found that early, sustained engagement and rapid offering of preexposure vaccination to affected communities successfully controlled the spread of the outbreak. The analysis is published in Annals of Internal Medicine.

Mpox is historically endemic to west and central Africa but spread significantly in other countries in 2022, primarily among the men who have sex with men (MSM) community. During this time, Montreal, Quebec, Canada, emerged as the site of the first large outbreak in North America.

Researchers from McGill University Health Centre, Montreal, Canada characterized and analyzed the epidemiologic, clinical, and demographic data from 402 persons with probable or confirmed cases of mpox in Montreal and the public health response by Montreal Public Health. The authors report that Montreal experienced its initial mpox outbreak in May 2022, followed by two peaks in early June and early July. This was followed by a decline in cases. Nearly all reported cases were among MSM who likely acquired the infection through sexual contact. Montreal public health authorities acted quickly to lead interventions to control the transmission. These interventions included early and sustained engagement with the affected communities; alerting clinicians to promote rapid case detection and reporting; performing case investigation and contact tracing; and contributing to the development of interim guidance on diagnostic testing, case and contact management, and recommended infection and control prevention measures. According to the authors, the prompt recognition of the importance of preexposure vaccination in at-risk populations and the extended offer of MVA-BN to tourists coming to Montreal led to many being vaccinated. They add that increasing and supporting equitable access to vaccines for at-risk populations worldwide should be a global priority for the prevention and control of mpox.

4. Physicians discuss strategies for managing chronic insomnia
All Beyond the Guidelines discussions are based on Grand Rounds from Beth Israel Deaconess Medical Center
Abstract: https://www.acpjournals.org/doi/10.7326/M22-2817
URL goes live when the embargo lifts
In a new Annals ‘Beyond the Guidelines,’ a clinical psychologist and sleep physician debate the management of a patient with chronic insomnia who has been treated with medications. All ‘Beyond the Guidelines’ features are based on the Department of Medicine Grand Rounds at Beth Israel Deaconess Medical Center (BIDMC) in Boston and include print, video, and educational components published in Annals of Internal Medicine.

Insomnia, which is characterized by persistent sleep difficulties in association with daytime dysfunction, is a common concern in clinical practice. Chronic insomnia disorder is defined as symptoms that occur at least 3 times per week and persist for at least 3 months. Recent guidelines published by the American Academy of Sleep Medicine (AASM) recommended multicomponent cognitive behavioral therapy (CBT) and a limited number of medications that might be useful for insomnia.

BIDMC Grand Rounds discussants, Eric S. Zhou, PhD, an Assistant Professor at Harvard Medical School and a clinical psychologist at Dana-Farber Cancer Institute, and Eric Heckman, MD, an Instructor at Harvard Medical School and sleep specialist and pulmonologist at Beth Israel Deaconess Medical Center, discuss the case of a 64-year-old man who experienced difficulty getting to sleep and early morning awakening for decades. The patient was prescribed zolpidem many years ago, which was initially taken as needed but now is a daily necessity to get to sleep. More recently, trazodone was added to his regimen. The patient has also been diagnosed with obstructive sleep apnea (OSA).

In their assessment, both Drs. Zhou and Heckman agree that CBT is the preferred intervention in the patient’s situation. Dr. Heckman would first evaluate and treat the patient for OSA and other comorbid conditions such as restless leg syndrome that might affect his sleep, while Dr. Zhou would dispel the commonly held belief that patients all require 8 hours of sleep per night as part of his treatment. Dr. Zhou and Mr. F would also collaborate on identifying his individual sleep need through a structured process involving sleep restriction and, subsequently, expansion. Dr. Heckman would consider a streamlined, clinic-based behavioral intervention focusing on sleep restriction and stimulus control if CBT was not accessible or acceptable to the patient. He would not insist on discontinuation of medications immediately but would attempt to stop trazodone followed by reduction in the dose of zolpidem over time as tolerated.

A complete list of ‘Beyond the Guidelines’ topics is available at www.annals.org/grandrounds.

Not-so private eyes: Eye movements hold clues to how we make decisions

Peer-Reviewed Publication

UNIVERSITY OF COLORADO AT BOULDER

New research led by scientists at the University of Colorado Boulder suggests that eyes may really be the window to the soul—or, at least, how humans dart their eyes may reveal valuable information about how they make decisions. 

The new findings offer researchers a rare opportunity in neuroscience: the chance to observe the inner workings of the human brain from the outside. Doctors could also potentially use the results to, one day, screen their patients for illnesses like depression or Parkinson’s Disease.

“Eye movements are incredibly interesting to study,” said Colin Korbisch, doctoral student in the Paul M. Rady Department of Mechanical Engineering at CU Boulder and lead author of the study. “Unlike your arms or legs, the speed of eye movements is almost totally involuntary. It’s a much more direct measurement of these unconscious processes happening in your brain.”

He and his colleagues, including researchers at Johns Hopkins University in Baltimore, published their findings in November in the journal Current Biology.

In the study, the team asked 22 human subjects to walk on a treadmill then choose between different settings displayed on a computer screen: a brief walk up a steep grade or a longer walk on flat ground. 

Researchers discovered that the subjects’ eyes gave them away: Even before they made their choices, the treadmill users tended to move their eyes faster when they looked toward the options they ended up choosing. The more vigorously their eyes moved, the more they seemed to prefer their choice. 

“We discovered an accessible measurement that will tell you, in only a few seconds, not just what you prefer but how much you prefer it,” said Alaa Ahmed, senior author of the study and associate professor of mechanical engineering at CU Boulder.

Shifty eyes

Ahmed explained that how or why humans make choices (Tea or coffee? Dogs or cats?) is notoriously difficult to study. Researchers don’t have many tools that will easily allow them to peer inside the brain. Ahmed, however, believes that our eyes could provide a glimpse into some of our thought processes. She’s particularly interested in a type of movement known as a “saccade.”

“The primary way our eyes move is through saccades,” Ahmed said. “That’s when your eyes quickly jump from one fixation point to another.”

Quickly is the key word: Saccades usually take just a few dozen milliseconds to complete, making them faster than an average blink. 

To find out if these darting motions give clues about how humans come to decisions, Ahmed and her colleagues decided to hit the gym.

In the new study, the team set up a treadmill on the CU Boulder campus. Study subjects exercised on various inclines for a period of time then sat down in front of a monitor and a high-speed, camera-based device that tracked their eye movements. While at the screen, they pondered a series of options, getting 4 seconds to pick between two choices represented by icons: Did they want to walk for 2 minutes at a 10% grade or for 6 minutes at a 4% grade? Once done, they returned to the treadmill to feel the burn based on what they chose. 

The team found that subjects’ eyes underwent a marathon of activity in just a short span of time. As they considered their options, the individuals flitted their eyes between the icons, first slowly and then faster. 

“Initially, the saccades to either option were similarly vigorous,” Ahmed said. “Then, as time passed, that vigor increased and it increased even faster for the option they eventually chose.”

The researchers also discovered that people who made the hastiest decisions—the most impulsive members of the group, perhaps—also tended to move their eyes more vigorously. Once the subjects decided on their pick, their eyes slowed again. 

“Real-time read-outs of this decision-making process typically require invasive electrodes placed into the brain. Having this more easily measured variable opens a lot of possibilities,” Korbisch said. 

Diagnosing illness

Flicks of the eye could matter for a lot more than understanding how humans make decisions. Studies in monkeys, for example, have suggested that some of the same pathways in the brain that help primates pick between this or that may also break down in people with Parkinson’s—a neurological illness in which individuals experience tremors, difficulty moving and other issues.

“Slowed movements aren’t just a symptom of Parkinson’s but also appear in a lot of mental health disorders, such as depression and schizophrenia,” Ahmed said. “We think these eye movements could be something that medical professionals track as a diagnostic tool, a way to identify the progress of certain illnesses.”

Eyes, in other words, could be windows to a lot more than just the soul.

Effective Prevention

Absolute Risk Reduction Supports More Equitable Vaccine Distribution Policies

Peer-Reviewed Publication

UNIVERSITY OF NEW MEXICO HEALTH SCIENCES CENTER

In a new study, New Mexico researchers using an alternative analysis based on evidence-based medicine found that the effectiveness of COVID vaccines is much greater in areas of the world with higher prevalence of infection – an approach that could lead to more equitable distribution of vaccines.

In a peer-reviewed paper published Dec. 12 in BMJ Open, the investigators calculated and compared absolute risk reduction (ARR) and the number needed to be vaccinated (NNV) in different geographical areas.

“At certain times during the pandemic, the NNV to prevent one hospitalization in some parts of the world was less than 1,000, whereas in other locations, it was more than 10,000,” said corresponding author Howard Waitzkin, MD, PhD, a professor emeritus at The University of New Mexico.

Until now, scientific publications about COVID-19 vaccines have assessed their effectiveness by measuring relative risk reduction, which compares people who receive vaccination with those who don’t.

Absolute risk reduction measures how much a vaccine reduces an individual’s baseline risk in a population. The number needed to be vaccinated indicates the number of people who should be vaccinated to prevent one adverse outcome, such as getting sick or needing hospitalization from COVID-19.

Adopting these alternative measures of vaccine effectiveness could guide better policies about distributing vaccines in COVID-19 and similar epidemics, the researchers contend.

“Vaccine distribution should target subpopulations with higher baseline risks of disease, rather than focusing only on the goal of vaccinating entire populations,” Waitzkin said.

“This approach could alleviate some economic and practical burdens of trying to provide vaccines for everyone, especially in poorer regions that have trouble obtaining enough vaccines due to what’s called vaccine apartheid.”

The research team also clarified other absolute measures to assess harms from vaccines.

“A risk-benefit analysis that compares absolute measures of harms and benefits can help set distribution policies,” said co-author Ella Fassler, a New Mexico-based investigative journalist with the New Mexico-based Allende Program in Social Medicine. “But scientific publications about the vaccines also have not reported these evidence-based medicine comparisons.”

Drinking coffee regularly after pregnancy may lower the risk of type 2 diabetes for women who had diabetes during pregnancy

NUS researchers at the Global Centre for Asian Women’s Health (GloW) found that among women who had gestational diabetes mellitus, coffee may potentially be a better substitute for other less healthy beverages in preventing or delaying the subsequent prog

Peer-Reviewed Publication

NATIONAL UNIVERSITY OF SINGAPORE, YONG LOO LIN SCHOOL OF MEDICINE

The prevalence of type 2 diabetes is projected to continue rising and one in three Singaporeans currently has a risk of developing diabetes in their lifetime. Several early-life cardiometabolic complications make identifying high-risk populations and application of diabetes preventive strategies paramount.

Among the high-risk groups are women who experienced diabetes during pregnancy, commonly known as gestational diabetes mellitus or gestational diabetes. Compared to the general healthy female population, these women may face a ten-fold higher risk of developing type 2 diabetes.

Current known research has found that, instead of artificially- and sugar-sweetened drinks, drinking two to five cups of either caffeinated or decaffeinated coffee a day is potentially a healthier substitute in delaying the onset or preventing type 2 diabetes.

This is likely due to the bioactive components in coffee, such as polyphenols, which are naturally-occurring plant micronutrients. Bioactive components are types of chemicals found in small amounts in plants and certain foods, such as fruits, vegetables, nuts, oils, and whole grains, and may promote good health.

This common and popular drink appears to reduce the risk of type 2 diabetes in the general population. However, whether it may also be beneficial among women who had gestational diabetes remained unknown.

To investigate this, Professor Cuilin Zhang, Director of the Global Centre for Asian Women’s Health (GloW) and a professor in the Department of Obstetrics and Gynecology at the Yong Loo Lin School of Medicine, National University of Singapore (NUS Medicine), with her team at GloW, in collaboration with the Harvard T.H. Chan School of Public Health and the National Institutes of Health (NIH), examined the roles of long-term coffee consumption after the complicated pregnancy and subsequent risk of type 2 diabetes among women with a history of gestational diabetes.

The team further examined coffee consumption with type 2 diabetes by replacing commonly consumed sugary drinks with coffee. Findings from this study, “Habitual coffee consumption and subsequent risk of type 2 diabetes in individuals with a history of gestational diabetes – a prospective study” was recently published in the American Journal of Clinical Nutrition.

In their study, the researchers followed more than 4,500 predominantly white female participants who had a history of gestational diabetes, for over 25 years, and examined the associations of long-term coffee consumption with subsequent risk of type 2 diabetes.

The consumption of caffeinated coffee among women after their pregnancies, was discovered to have a linear inverse association with the risk of type 2 diabetes. Compared to those who did not drink caffeinated coffee at all, among those who drank one cup of caffeinated coffee or less, two to three cups, and four and more cups a day, the risk of type 2 diabetes was reduced by 10%, 17%, and 53% respectively.

Interestingly, decaffeinated coffee was not associated with the risk of type 2 diabetes in their study. However, this null finding might be due to the relatively small number of women who consumed decaffeinated coffee, so that the study was not able to detect a significant association.

More importantly, replacing artificially sweetened and sugar-sweetened beverages with caffeinated coffee also reduces the risk, by 10% for a cup of artificially sweetened beverage, and 17% for a cup of sugar-sweetened one.

“Thus far, the overall findings suggest that caffeinated coffee, when consumed properly (two to five cups per day, without sugar and whole-fat/high-fat dairy), could be incorporated into a relatively healthy lifestyle for certain population,” noted Professor Zhang.

“The beneficial roles of coffee have been consistently suggested across diverse populations, including Asians. Coffee is a popular beverage choice in Singapore, but local coffee drinking culture and behaviours may vary among individuals, such as brewing methods, drinking frequency, and other condiments contained in the coffee. Thus, more studies are needed to examine the roles of coffee consumption in the local context with major health outcomes,” concluded Professor Zhang.

Adding on to Professor Zhang’s point, Dr Jiaxi Yang, the first author of the study and a postdoctoral research fellow at GloW and the Department of Obstetrics and Gynecology at NUS Medicine, said, “Although coffee presents as a potentially healthier alternative to sweetened beverages, the health benefits of coffee vary and much depend on the type and the amount of condiments, like sugar and milk, that you add into your coffee.” Dr Yang is currently leading the working group of Nutrition and Lifestyle at GloW.

However, concerns should be given when coffee is taken in excessive amounts. It also needs to be emphasised that certain groups should be careful about drinking coffee. Not much is known about the effects of coffee on pregnancies, foetuses and children.
