Early career researchers win funding
John Krais, PhD, a researcher at Fox Chase Cancer Center in Philadelphia, has received a $75,000 grant from the Ovarian Cancer Research Alliance.
Dr. Krais received the 2-year grant to fund his investigation into DNA repair processes in BRCA1-mutant cancers, which will focus on the RNF168 protein.
Seven other early career researchers have joined the Parker Institute for Cancer Immunotherapy as part of the Parker Scholars, Parker Bridge Scholars, and Parker Fellows programs.
These researchers will receive a total of up to $3.1 million in funding to further their research on immunotherapies for cancers. Cécile Alanio, MD, PhD, a Parker Bridge Scholar at the University of Pennsylvania in Philadelphia, is researching the impact of infections on T cells in healthy patients with the goal of revealing new approaches to immunotherapy for cancer patients.
Kenneth Hu, PhD, a Parker Scholar at the University of California, San Francisco, plans to use single-cell profiling and microscopy to gain a better understanding of immune cells’ interactions in the tumor microenvironment.
Xihao (Sherlock) Hu, PhD, a Parker Scholar at the Dana-Farber Cancer Institute in Boston, plans to study the interactions between tumor antigens and tumor-infiltrating B cells.
Justin Eyquem, PhD, a Parker Fellow at the University of California, San Francisco, plans to use a genome-editing platform he developed to improve the function of chimeric antigen receptor (CAR) T cells in solid tumors.
Tijana Martinov, PhD, a Parker Scholar at Fred Hutchinson Cancer Research Center in Seattle, is seeking to produce T cells that can target multiple myeloma cells.
Sierra McDonald, a PhD candidate and Parker Scholar at the University of Pennsylvania, is investigating ways to improve responses to CAR T-cell therapy by studying the HMG-box family of proteins.
Roberta Zappasodi, PhD, of Memorial Sloan Kettering Cancer Center in New York, is transitioning from a Parker Scholar to a Parker Bridge Scholar. She previously characterized a population of immune-suppressive T cells. Now, she is working to determine how these cells can be used to improve the efficacy of checkpoint inhibition.

CHEST updates guidelines on PAH
The American College of Chest Physicians® (CHEST) has published updates to the evidence-based guidelines on therapy for pulmonary arterial hypertension (PAH). In the latest evidence-based guideline, Therapy for Pulmonary Arterial Hypertension in Adults: Update of the CHEST Guideline and Expert Panel Report, experts provide 78 evidence-based recommendations for appropriate use in treating patients with PAH.
“New recommendations and ungraded consensus-based statements were developed in this update based on new studies that were published since the 2014 guidelines. In addition, an evidence-based and consensus-driven treatment algorithm was created to guide the clinician through an organized approach to management,” says CHEST Pulmonary Arterial Hypertension Guidelines Committee Co-Chair, Deborah Jo Levine, MD, FCCP.
As part of the guideline development process, the panel updated the systematic review on the same clinical questions and criteria. Based on the results of the systematic review, the panel developed two new recommendations about pharmacologic therapy for PAH:
•For treatment-naive patients with PAH who are World Health Organization (WHO) functional class II and III, we suggest initial combination therapy with ambrisentan and tadalafil to improve 6-minute walk distance (6MWD).
•For stable or symptomatic patients with PAH on background therapy with ambrisentan, we suggest the addition of tadalafil to improve 6MWD.
The complete guideline article is free to view in the Online First section of the journal CHEST®.

Thyroid Hormones Predict Readmission After Aortic Surgery
Thoracic endovascular aortic repair (TEVAR) is a “young technology with several unknowns,” say researchers from Shantou University Medical College, and Wuhan Asia Heart Hospital, both China. One of those unknowns is the risk factors for prognosis after TEVAR.
After all, thyroid hormones are critical to many areas of heart health, such as vascular remodeling; hypothyroidism can aggravate hypertension; and low levels of free thyroxine (FT4) influence arterial stiffness and C-reactive protein. In spite of the many links, however, the relationship between subclinical hypothyroidism and cardiovascular disease has not been fully elucidated, the researchers say. They conducted a study to evaluate whether thyroid hormones predicted early (30 days) and mid-term (12 months) aorta-related adverse events (AEs), such as death, progression of aortic disease, organ failure, or lower limb ischemia; and aorta-related readmissions.
In their study, 338 patients were stratified according to their levels of FT4 before undergoing TEVAR. Of the enrolled patients, 288 were followed up at 12 months for readmission; 292 were followed up on AEs.
Patients with low normal levels of FT4 had a greater risk of readmission after thoracic endovascular aortic repair. Within 30 days, the incidence of AEs and readmission were 2.7% and 4.1%; within 12 months, 8.9% and 13.5%. After the researchers adjusted for confounders, the patients with the lowest FT4 quartile were at significantly greater risk for readmission than those in the highest-quartile group, at both early and mid-term follow-up.
The same did not hold true for AEs. The researchers say this is not uncommon in studies of predictors of AEs and readmission: Factors that are weak predictors of readmission tend to be strong predictors of AEs, and vice versa.

Nonadherent Diabetes Patients: An Unexpected Group
“Time-specific” dosing of insulin can be an obstacle to adherence for patients with complicated, busy lives. More than half of patients with type 2 diabetes do not achieve their target HbA1c of 7% after insulin is added to their treatment regimen. Researchers from CAPHRI School for Public Health and Primary Care, and CARIM Institute in The Netherlands, who surveyed 1,483 adults with diabetes suggest that it may be time to rethink both prescribing and patient education, in part because of who fell into the nonadherent group.
The researchers conducted a web-based self-report survey. Of the respondents, 58% used bolus insulin before meals, 24% after meals, and 18% before, during, or after meals. The researchers excluded the “mixed” cohort, including 1,218 in the analysis.
Half the respondents in the postmeal cohort reported experiencing minor hypoglycemic events at least once a week compared with 35% of the premeal cohort. Similarly, more in the postmeal group had had major hypoglycemic events (38% vs 26%). The postmeal respondents also were more likely to have HbA1c ≥ 9% (40% vs 29%). And they were less likely to report always testing their blood glucose before injecting insulin (36% vs 54%).
Perhaps contrary to some expectations, the respondents who injected insulin postmeal were younger, had shorter duration of diabetes, had the highest level of college or university education, were more likely to be employed, and more frequently participated in diabetes education programs (including one-on-one programs).
The researchers say those data suggest that factors other than lack of diabetes education, education, or low socioeconomic status should be considered in explaining the nonadherence. They add that some research has shown that education programs have an “inconsistent relationship with patient adherence.” They suggest that such programs might be improved by placing greater emphasis on the importance of dosing insulin before meals.
Of the nearly 20% of patients who use insulin treatment, > 90% receive bolus insulin. The researchers note that respondents preferred a form of bolus insulin they can administer before, after, or during meals as they see fit. The respondents who injected postmeal were more likely than the premeal respondents to prefer this formulation.

More than half of patients with type 2 diabetes do not achieve their target HbA1c of 7% after insulin is added to their treatment regimen. Researchers from CAPHRI School for Public Health and Primary Care, and CARIM Institute in The Netherlands, who surveyed 1,483 adults with diabetes suggest that it may be time to rethink both prescribing and patient education, in part because of who fell into the nonadherent group.
The researchers conducted a web-based self-report survey. Of the respondents, 58% used bolus insulin before meals, 24% after meals, and 18% before, during, or after meals. The researchers excluded the “mixed” cohort, including 1,218 in the analysis.
Half the respondents in the postmeal cohort reported experiencing minor hypoglycemic events at least once a week compared with 35% of the premeal cohort. Similarly, more in the postmeal group had had major hypoglycemic events (38% vs 26%). The postmeal respondents also were more likely to have HbA1c ≥ 9% (40% vs 29%). And they were less likely to report always testing their blood glucose before injecting insulin (36% vs 54%).
Perhaps contrary to some expectations, the respondents who injected insulin postmeal were younger, had shorter duration of diabetes, had the highest level of college or university education, were more likely to be employed, and more frequently participated in diabetes education programs (including one-on-one programs).
The researchers say those data suggest that factors other than lack of diabetes education, education, or low socioeconomic status should be considered in explaining the nonadherence. They add that some research has shown that education programs have an “inconsistent relationship with patient adherence.” They suggest that such programs might be improved by placing greater emphasis on the importance of dosing insulin before meals.
Of the nearly 20% of patients who use insulin treatment, > 90% receive bolus insulin. The researchers note that respondents preferred a form of bolus insulin they can administer before, after, or during meals as they see fit. The respondents who injected postmeal were more likely than the premeal respondents to prefer this formulation.

Epigenetics and Disasters
The configuration of the DNA bordering a gene dictates under what conditions a gene is expressed. Random errors or mutations affecting the neighboring DNA or the gene itself can affect how the gene functions. Epigenetics is an emerging field of science looking at environmental and psychosocial factors that do not directly cause mutations but still affect how genes are expressed with implications for the development and inheritance of disease. These external influences are thought to affect why some segments of DNA become accessible for protein production while other segments may not.
Disasters represent stressors with potential for epigenetic impact. Women who were pregnant during the 1998 Quebec ice storm were found to have a correlation between maternal objective stress and a distinctive pattern of DNA methylation in their children 13 years later (Cao-Lei L, et al. PLoS ONE. 2014;9[9] e10765). Methylation is known to affect the activity of a DNA segment and how genes are expressed. Associations have also been found between the severity of hurricanes and the prevalence of autism in the offspring of pregnant women experiencing these disasters (Kinney DK, et al. J Autism Dev Disord. 2008;38:481).
Anthropogenic hazards may also affect the offspring of survivors as suggested by studies of civil war POWs and Dutch Hunger Winter during WW II (Costa, DL, et al. Proc Nat Acad Sci 2018;. 115:44; Heijmans BT et al. Proc Nat Acad Sci. 2008;105[44]: 17046-9).
Epigenetics represents an area for additional research as natural and man-made disasters increase.

Medicare Competitive Bidding Process Update
Medicare’s Competitive Bidding Program (CBP), mandated since 2003, asks providers of specific durable medical equipment (including oxygen) to submit competing proposals for services. The best offer is then awarded a 3-year contract. Recently, several reforms to CBP have been proposed. The payment structure has changed to “lead-item pricing,” where a single bid in each category is selected and payment amounts for each product are then calculated based on pricing ratios and fee schedules (CMS DMEPOS Competitive Bidding).
This is in contrast to the prior method of median pricing, which caused financial difficulty and access concerns (Council for Quality Respiratory Care. The Rationale for Reforming Medicare Home Respiratory Therapy Payment Methodology. 2018). Budget neutrality requirements should relax, and oxygen payment structures improve. These proposed changes also include improved coverage of liquid oxygen and addition of home ventilator supplies.
However, effective January 1, 2019, all CBP is suspended through CMS. During the anticipated 2-year gap, any Medicare-enrolled supplier will be able to provide items until new contracts are awarded. Pricing during the gap period is based on a current single price plus consumer price index. These changes will impact CHEST members and their patients moving forward. During the temporary gap period, some areas are seeing decreased accessibility of some DME due to demand. Once reinstated, the changes to the oxygen payment structure should improve access and reduce out-of-pocket costs. The Practice Operations NetWork will continue to provide updates on this topic as they become available.

Transplant
Medicare Part D Plans Can Deny Coverage of Select Immunosuppressant Medications in Solid Organ Transplant Recipients
An alarming problem has emerged with some solid organ transplant recipients experiencing immunosuppressant medication claim denials by Medicare Part D plans. Affected patients are those who convert from some other insurance (ie, private insurance or state Medicaid) to Medicare after their transplant and, therefore, rely on Medicare Part D for immunosuppressant drug coverage.
Insurance companies who offer Medicare Part D plans must follow the rules described in the Medicare Prescription Drug Benefit Manual.1 Although the Manual mandates that all immunosuppressant medications are on plan formularies, Part D plans are only required to cover immunosuppressant medications when used for indications approved by the Food and Drug Administration (FDA) or for off-label indications supported by the Centers for Medicare & Medicaid Services (CMS)-approved compendia (Drugdex® and AHFS Drug Information®).
A recent study examining the extent of the problem demonstrated non-renal organ transplant recipients are frequently prescribed and maintained on at least one medication vulnerable to Medicare Part D claim denials at 1 year posttransplant (lung: 71.1%; intestine: 39.7%; pancreas: 36.8%; liver: 19.7%; heart: 18.5%).2 Lung transplant recipients are most vulnerable since no immunosuppressant is FDA-approved for use in lung transplantation, and CMS-approved compendia only support off-label use for tacrolimus and cyclosporine in this population. Therefore, mycophenolate mofetil, mycophenolic acid, azathioprine, everolimus, and sirolimus are vulnerable to denial by Medicare Part D plans when used in lung transplant recipients. Over 95% of lung transplant recipients are maintained on an anti-metabolite, with the majority (88%) maintained on mycophenolate, so this is frequently impacted.2,3 While the transplant community is aware of this issue and has begun work to correct it, it has yet to be solved.2,4 In the meantime, if transplant recipients have been denied for this off-label and off-compendia reason, and appeals of those decisions have also been denied, options for obtaining the denied immunosuppressant medication include discount programs, foundation/grant funding, and industry-sponsored assistance programs.

Women’s Health
Cannabis Use Affects Women Differently
As we enter an era of legalization, cannabis use is increasingly prevalent. Variances in the risks for women and men have been observed. For most age groups, men have higher rates of use or dependence on illicit drugs than women. However, women are equally likely as men to progress to a substance use disorder. Women may be more susceptible to craving and relapse , which are key phases of the addiction cycle. A study on use among adolescents concluded there was preliminary evidence of a faster transition from initiation of marijuana use to regular use in women, when compared with men (Schepis, et al. J Addict Med. 2011;5[1]:65).
Research studies suggest that marijuana impairs spatial memory in women more so than in men. Studies have suggested that teenage girls who use marijuana may have a higher risk of brain structural abnormalities associated with regular marijuana exposure than teenage boys (Tapert, et al. Addict Biol. 2009;14[4]:457).
A study published in Psychoneuroendocrinology showed that cannabinoid receptor binding site densities exhibit sex differences and can be modulated by estradiol in several limbic brain regions. These findings may account for the sex differences observed with respect to the effects of cannabinoids (Riebe, et al. Psychoneuroendocrinology. 2010;35[8]:1265).
Further research is needed to expand our understanding of the interactions between cannabinoids and sex steroids. Detoxification treatments tailored toward women and men with cannabis addiction show a promising future and necessitate further research.
