Background: Elexacaftor/tezacaftor/ivacaftor (ETI) is a highly effective therapy that improves lung disease in people with cystic fibrosis (pwCF), but its effect on glucose tolerance and insulin secretion is unclear.

Methods: PROMISE is a multicenter prospective, observational study of ETI in pwCF ≥12 years and at least one F508del allele. The PROMISE Endocrine sub-study (PROMISE-ENDO) enrolled participants at 10 CF Centers where hemoglobin A1c (HbA1c) was collected and 3-hour oral glucose tolerance tests (OGTT) conducted to examine glucose tolerance, glucose excursions, insulin secretory rates (deconvolution of C-peptide) and sensitivity (oral minimal model) prior to ETI and 12-18 months (mos) and 24-30 mos following ETI initiation.

Transplanted islet functional β-cell mass is measured by the β-cell secretory capacity derived from the acute insulin response to glucose-potentiated arginine (AIRpot), however, data are limited beyond one-year post-transplant for individuals with type 1 diabetes. We evaluated changes in β-cell secretory capacity in a single-center longitudinal analysis and examined relationships with measures of islet cell hormone metabolism and clinical measures of graft function (mixed-meal tolerance test [MMTT] C-peptide, BETA-2 score, and continuous glucose monitoring [CGM]). Eleven individuals received purified human pancreatic islets over one or two intra-portal infusions to achieve insulin-independence and were followed over a median (IQR) 6 (5-7) years.

Article Synopsis
  • The study aimed to assess the effectiveness of a school-based telehealth program, IPT-AST, for preventing depression in adolescents compared to standard services.
  • A total of 242 adolescents with high depression scores participated and provided data at baseline, 2 months, and 3 months to evaluate changes in depression and anxiety symptoms.
  • Results indicated that IPT-AST participants experienced significantly greater reductions in anxiety symptoms and were more engaged with the program, suggesting that telehealth interventions can be both feasible and beneficial for adolescent mental health.

Article Synopsis
  • Poor prenatal sleep quality in mothers is linked to negative outcomes for both the mother and infant, including changes in brain development and increased anxiety-like behaviors.
  • A study involving 116 mother-infant pairs used surveys to assess maternal sleep quality and MRI scans to examine neonatal brain development, specifically focusing on the uncinate fasciculus.
  • Results showed that poorer maternal sleep during pregnancy correlated with higher levels of white matter in infants, which then related to greater infant negative emotionality, indicating that maternal sleep is an important environmental factor influencing child development.

Background: Multiple listing (ML) is a practice used to increase the potential for transplant but is controversial due to concerns that it disproportionately benefits patients with greater access to health care resources.

Research Question: Is there disparity in ML practices based on social deprivation in the United States and does ML lead to quicker time to transplant?

Study Design And Methods: A retrospective cohort study of adult (≥ 18 years of age) lung transplant candidates listed for transplant (2005-2018) was conducted. Exclusion criteria included heart only or heart and lung transplant and patients relisted during the observation period.

Objective: Although telehealth psychotherapies have been studied for over 20 years, mental health services remained largely delivered in person until the COVID-19 pandemic forced clinics to reconsider the utility of telehealth psychotherapy. This study aims to compare patient engagement in in-person versus telehealth services in outpatient psychotherapy for mood and anxiety disorders.

Method: A cohort investigation was conducted, using a propensity score matched sample, extracted from an electronic health record (EHR) to compare engagement in psychotherapy for 762 patients who used in-person services before the pandemic to a cohort of 762 patients who used telehealth psychotherapy after the onset of COVID-19.

Article Synopsis
  • Shortened gestation leads to significant childhood health issues, and there's a need for public health initiatives to improve gestational age at birth, particularly in light of its connection to prenatal maternal depression.
  • This study involved 226 pregnant individuals in a randomized clinical trial comparing interpersonal psychotherapy (IPT) to standard care, with evaluations on depression symptoms and gestational length conducted throughout pregnancy.
  • Results indicated that a reduction in prenatal depression, especially in those receiving IPT, was associated with a higher likelihood of delivering full-term babies (≥39 weeks), suggesting that treating maternal depression may positively impact gestation duration.

Background: Prenatal glucocorticoids are one of the most widely proposed prenatal programming mechanisms, yet few studies exist that measure fetal cortisol via neonatal hair. Neonatal hair provides a window into the fetal experience and represents cortisol accumulation in the third trimester of pregnancy. In the current study, we test the links between two types of anxiety over the course of gestation (pregnancy-related anxiety and general anxiety) with neonatal hair cortisol.

Lung transplantation lags behind other solid organ transplants in donor lung utilization due, in part, to uncertainty regarding donor quality. We sought to develop an easy-to-use donor risk metric that, unlike existing metrics, accounts for a rich set of donor factors. Our study population consisted of n = 26 549 adult lung transplant recipients abstracted from the United Network for Organ Sharing Standard Transplant Analysis and Research file.

Context: Elexacaftor/tezacaftor/ivacaftor (ETI; Trikafta) enhances aberrant cystic fibrosis transmembrane conductance regulator function and may improve the insulin secretory defects associated with a deterioration in clinical outcomes in pancreatic insufficient cystic fibrosis (PI-CF).

Objective: This longitudinal case-control study assessed changes in β-cell function and secretory capacity measures over 2 visits in individuals with PI-CF who were initiated on ETI after the baseline visit (2012-2018) and (1) restudied between 2019 and 2021 (ETI group) vs (2) those restudied between 2015 and 2018 and not yet treated with cystic fibrosis transmembrane conductance regulator modulator therapy (controls).

Methods: Nine ETI participants (mean ± SD age, 25 ± 5 years) and 8 matched controls were followed up after a median (interquartile range) 5 (4-7) and 3 (2-3) years, respectively (P < .

Objective: Digital delivery of mindfulness-based cognitive therapy through the Mindful Mood Balance (MMB) program is clinically effective (Segal et al., 2020); however, the mechanisms through which this program delivers its benefits have not been established.

Method: This study investigates the differential impact of the MMB program paired with usual depression care (UDC) compared to UDC alone on the putative targets of self-reported mindfulness, decentering, and rumination and the extent to which change in these targets mediates subsequent depressive relapse among a sample of predominantly White, female participants, with residual depressive symptoms.

This paper presents two studies conducted to develop and evaluate a new pragmatic measure of therapist adherence to Dialectical Behavior Therapy (DBT): the DBT Adherence Checklist for Individual Therapy (DBT AC-I). Study 1 used item response analysis to select items from the gold standard DBT Adherence Coding Scale (DBT ACS) using archival data from 1271 DBT sessions. Items were then iteratively refined based on feedback from 33 target end-users to ensure relevance, usability, and understandability.
