OBJECTIVES/OBJECTIVE:Maternal stress has been associated with early child obesity through pathways related to decreased exclusive breastfeeding and increased non-responsive maternal-infant feeding styles. We sought to gain an in-depth understanding of how maternal stress, sadness, and isolation are perceived to affect feeding, in order to inform modifiable targets of intervention. METHODS:We conducted semi-structured qualitative interviews with Hispanic mothers living in poverty with young infants between 3 and 7 months old (n=32) from the intervention group of a randomized controlled trial of an early child obesity prevention intervention (Starting Early Program). Bilingual English-Spanish interviewers conducted the interviews, which were audio recorded, transcribed, and translated. Building on an existing theoretical framework developed by the National Scientific Council on the Developing Child, we used an iterative process of textual analysis to code the transcripts, until thematic saturation was reached. RESULTS:Three key themes were described: 1) maternal stress responses were varied and included: positive (brief and mild), tolerable (sustained but limited long-term impacts), or toxic stress (sustained and severe); 2) buffers included support from family, infants, health care providers, social service programs, and community organizations; 3) perceived effects on infant feeding: decreased breastfeeding due to concerns about stress passing directly through breast milk and indirectly through physical closeness, and increased non-responsive feeding styles. CONCLUSIONS:Maternal stress, particularly toxic stress, was perceived to negatively affect infant feeding. Mothers reported disrupting healthy feeding to avoid infant exposure to stress. Interventions to enhance buffering may help to mitigate toxic stress and promote healthy feeding interactions.

Rationale & Objective/UNASSIGNED:Posttransplant diabetes mellitus (DM) after kidney transplantation increases morbidity and mortality, particularly in older and obese recipients. We aimed to examine the impact of immunosuppression selection on the risk of posttransplant DM among both older and obese kidney transplant recipients. Study Design/UNASSIGNED:Retrospective database study. Setting & Participants/UNASSIGNED:Kidney-only transplant recipients aged ≥18 years from 2005 to 2016 in the United States from US Renal Data System records, which integrate Organ Procurement and Transplantation Network/United Network for Organ Sharing records with Medicare billing claims. Exposures/UNASSIGNED:Various immunosuppression regimens in the first 3 months after transplant. Outcomes/UNASSIGNED:Development of DM >3 months-to-1 year posttransplant. Analytical Approach/UNASSIGNED:We used multivariable Cox regression to compare the incidence of posttransplant DM by immunosuppression regimen with the reference regimen of thymoglobulin (TMG) or alemtuzumab (ALEM) with tacrolimus + mycophenolic acid + prednisone using inverse propensity weighting. Results/UNASSIGNED:(aHR, 0.63; 95% CI, 0.46-0.87). Limitations/UNASSIGNED:Retrospective study and lacked data on immunosuppression levels. Conclusions/UNASSIGNED:The beneficial impact of steroid avoidance using tacrolimus on posttransplant DM appears to differ by patient age and induction regimen.

Background/UNASSIGNED:Posttransplant diabetes (PTD), a major complication after kidney transplantation (KT), is often attributable to immunosuppression. The risk of PTD may increase with more potent steroid maintenance and older recipient age. Methods/UNASSIGNED:Using United States Renal Data System data, we studied 12 488 adult first-time KT recipients (2010-2015) with no known pre-KT diabetes. We compared the risk of PTD among recipients who underwent early steroid withdrawal (ESW) versus continued steroid maintenance (CSM) using Cox regression with inverse probability weighting to adjust for confounding. We tested whether the risk of PTD resulting from ESW differed by recipient age (18-29, 30-54, and ≥55 y). Results/UNASSIGNED:). Conclusions/UNASSIGNED:The beneficial association of ESW with decreased PTD was more pronounced among recipients aged ≥55, supporting an age-specific assessment of the risk-benefit balance regarding ESW.

PURPOSE/OBJECTIVE:Population-based surveys are possible sources from which to draw representative control data for case-control studies. However, these surveys involve complex sampling that could lead to biased estimates of measures of association if not properly accounted for in analyses. Approaches to incorporating complex-sampled controls in density-sampled case-control designs have not been examined. METHODS:We used a simulation study to evaluate the performance of different approaches to estimating incidence density ratios (IDR) from case-control studies with controls drawn from complex survey data using risk-set sampling. In simulated population data, we applied four survey sampling approaches, with varying survey sizes, and assessed the performance of four analysis methods for incorporating survey-based controls. RESULTS:Estimates of the IDR were unbiased for methods that conducted risk-set sampling with probability of selection proportional to survey weights. Estimates of the IDR were biased when sampling weights were not incorporated, or only included in regression modeling. The unbiased analysis methods performed comparably and produced estimates with variance comparable to biased methods. Variance increased and confidence interval coverage decreased as survey size decreased. CONCLUSIONS:Unbiased estimates are obtainable in risk-set sampled case-control studies using controls drawn from complex survey data when weights are properly incorporated.

Background/UNASSIGNED:Prior to the COVID-19 pandemic, about half of patients from populations that sought care in neurology tried complementary and integrative therapies (CITs). With the increased utilization of telehealth services, we sought to determine whether patients also increased their use of virtual CITs. Methods/UNASSIGNED:We examined datasets from two separate cross-sectional surveys that included cohorts of patients with neurological disorders. One was a dataset from a study that examined patient and provider experiences with teleneurology visits; the other was a study that assessed patients with a history of COVID-19 infection who presented for neurologic evaluation. We assessed and reported the use of virtual (and non-virtual) CITs using descriptive statistics, and determined whether there were clinical characteristics that predicted the use of CITs using logistic regression analyses. Findings/UNASSIGNED:Patients who postponed medical treatment for non-COVID-19-related problems during the pandemic were more likely to seek CITs. Virtual exercise, virtual psychotherapy, and relaxation/meditation smartphone applications were the most frequent types of virtual CITs chosen by patients. In both studies, age was a key demographic factor associated with mobile/virtual CIT usage. Interpretations/UNASSIGNED:Our investigation demonstrates that virtual CIT-related technologies were utilized in the treatment of neurologic conditions during the pandemic, particularly by those patients who deferred non-COVID-related care.

Background/UNASSIGNED:Health providers' perceived sense of knowledge, competency, and self-efficacy to support the needs of their patients contributes to optimal patient health outcomes. With regards to mental health service delivery in Kenya, this area needs further exploration. Guided by the e-health technology acceptance mode, the needs and preferences of health care providers around mental health training for clinical management and their ability to intervene in peripartum adolescent mental health care are explored. We probed how well-equipped service providers are, their engagement with technology to learn and offer services. The health care provider's technology use preferences were also explored. Method/UNASSIGNED:Guided by a human-centered design-focused qualitative inquiry we interviewed 20 specialists around their needs, perspectives, and preferences for digitized mental health screening and intervention. Mean age was 44.2 years, (range of 32-58 years), 25% (5) males and 75% (15) females. After a written consenting process, the online interviews (30-45 min) were conducted in April 2021, once personal information was de-identified interviews were transcribed and coded. Thematic analysis was used and we combined rapid appraisal of Google Jamboard online storyboards to do individual human-centered design personas alongside. Results/UNASSIGNED:Our participants were well-exposed to digital technologies. Prohibitive costs of data bundles, lack of funds for consistent online engagement, high workload, and instability of access to appropriate gadgets were found to be barriers to e-health training. Emerging opportunities were well-identified adolescent mental health service and intervention needs, willingness to take online courses offered on learning platforms, and wish for these to be disseminated through diverse social media. Other recommendations were the need to have a user-friendly interface such as data-light engaging and practical materials including animations, short, group-based learning. Conclusion/UNASSIGNED:Understanding contextual factors that influence perceived usefulness and ease of use of the remote/digital components would be critical for e-training development and its uptake.

INTRODUCTION: The pulmonary embolism severity index (PESI) score is a well-known and validated clinical tool, utilized to predict 30-day mortality in patients with pulmonary embolism (PE). It is used to identify low-risk individuals (PESI < =85) who can be safely started on novel oral anticoagulation agents (NOAC) and discharged from the Emergency Department (ED). After calculating the PESI score in all patients admitted for PE within a 3-year period at a community hospital, this study first estimated the fraction of low-risk patients who ended up getting admitted. Additionally, this study compared the prevalence of right heart strain (RHS), incidence of bleeding events, and mortality rates between the low-risk and high-risk (PESI >85) cohorts.
METHOD(S): This study is a retrospective chart review of patients admitted with a primary diagnosis of PE to Mercy Fitzgerald Hospital from January 2018 to March 2021. The Fisher test was used to compare odds ratios (OR) of RHS on initial CT angiogram of the chest, bleeding events after initiation of the anticoagulation (drop in hemoglobin > 2 g/dL, positive hemoccult status, episodes of overt bleeding), and death rates between low-risk and high-risk groups. PRISM statistical software was used for statistical analysis.
RESULT(S): 211 patients were included in this study. 102 (48.3%) patients were categorized as low-risk and 109 (51.7%) as high-risk. RHS was present in 16 patients of the low-risk group (2 of which had saddle PE) versus 41 in the high-risk group (OR 0.39, CI [0.2-0.76], p 0.005). Bleeding after initiation of anticoagulation was observed in 2 patients in the low-risk versus 5 patients in the high-risk group (OR 0.42, CI [0.08-2], p 0.45). None of the patients in the low-risk group died during the admission compared to 6 patients from the high-risk group (OR non reported, CI [0-0.74], p 0.03).
CONCLUSION(S): When factoring in patients with RHS on initial imaging, 40.7% of the patients hospitalized for PE potentially could have been discharged safely for outpatient management based on this study. The patients who were identified as high risk had a higher occurrence of RHS and had significantly higher mortality compared to the low-risk group. The rate of bleeding events after initiation of anticoagulation among both groups was not statistically different

OBJECTIVES/OBJECTIVE:The number of older adults on methadone maintenance treatment (MMT) for opioid use disorder is increasing, but little is known about the characteristics and healthcare needs of this aging treatment population. This population may experience accelerated aging due to comorbidities and health behaviors. The aim of this study was to compare the prevalence of geriatric conditions among adults age ≥50 on MMT to a nationally representative sample of community-dwelling older adults. METHODS:We performed a geriatric assessment on 47 adults age ≥50 currently on MMT enrolled in 2 opioid treatment programs, in New York City and in East Providence, Rhode Island. We collected data on self-reported geriatric conditions, healthcare utilization, chronic medical conditions, physical function, and substance use. The results were compared to 470 age, sex, and race/ethnicity-matched adults in the national Health and Retirement Study. RESULTS:The mean age of the study sample was 58.8 years and 23.4% were female. The most common chronic diseases were hypertension (59.6%) and arthritis (55.3%) with 66% reporting ≥2 diseases. For geriatric conditions, adults on MMT had a significantly higher prevalence of mobility, hearing, and visual impairments as well as falls, urinary incontinence, chronic pain, and insomnia than the Health and Retirement Study sample. CONCLUSIONS:Older adults on MMT in 2 large opioid treatment programs have a high prevalence of geriatric conditions. An interdisciplinary, geriatric-based approach to care that focuses on function and addresses geriatric conditions is needed to improve the health of this growing population.

BACKGROUND:National guidelines recommend different pharmacologic management of hypertension (HTN) without comorbidities for Black/African Americans (BAA) compared with non-BAA. We sought to 1) identify if these recommendations have influenced prescription patterns in BAA and 2) identify the differences in uncontrolled HTN in BAA on different antihypertensive medications. METHODS:We constructed a linked retrospective observational cohort using 2 years of electronic health records data, comprising of patients aged 18 to 85 with HTN on 1- or 2-drug regimens, including angiotensin-converting enzyme inhibitors (ACE), angiotensin receptor blockers (ARB), thiazide diuretics, or calcium channel blockers (CCB). We examined prescribing differences and HTN control in BAA versus non-BAA. RESULTS:< .001). For each drug regimen, there was more variation in HTN control within each group than between BAA and non-BAA. CONCLUSIONS:Providers seem to be following race-based guidelines for HTN, yet HTN control for BAA remains worse than non-BAA. An individualized approach to HTN therapy for all patients may be more important than race-based guidelines.
