The most optimal school recruitment strategies for school-based obesity prevention and health promotion research in the United States: A systematic review with Delphi study.

This systematic review with the Delphi study aimed to identify effective and resource-efficient (optimal) strategies for recruiting schools into health promotion interventions in the United States. A literature search was conducted in PubMed, Cochrane Library, and CINAHL (EBSCO). A total of 116 interventions reported in 160 articles were included. Most school-based interventions did not report data regarding school recruitment duration (81%), target school size (63%), and school recruitment strategies (78%). Further, no details were provided regarding the reasons for declining to participate despite being eligible. For the Delphi, responses from 23 researchers in school-based clinical trials were collected. A qualitative descriptive approach was used for coding responses and collapsed into higher-order categories based on school recruitment strategies. Delphi participants reported that (1) creating new or leveraging pre-existing partnerships, (2) intervention champion, (3) minimal school disruptions, (4) working with open mind/flexibility, and (5) transparent communication are the most optimal school recruitment strategies. Staff time and travel were the most frequently reported costs for implementing those strategies. The overall trend in school-based obesity prevention intervention studies illustrates the importance of a better understanding school recruitment. Improved reporting can allow researchers to budget their time and resources better and provide greater confidence in reaching their target school size.

How Social Connectedness Helps Patients Stay Home After Hospital at Home Enrollment: A Mixed Methods Study.

BACKGROUND: While enrolled in Hospital at Home (HaH) programs, patients rely on their social network to provide supportive behaviors that are routinely provided by hospital staff in the inpatient setting. OBJECTIVE: This study investigated how social connectedness is associated with patient outcomes in a HaH program. DESIGN: The explanatory iterative sequential mixed methods design included an electronic health record review to collect quantitative measures to describe the severity of patient illness and healthcare utilization and then qualitative interviews to explain quantitative findings. PARTICIPANTS: The quantitative phase included 100 patients (18 years or older) admitted to the hospital who were subsequently enrolled in the HaH program. In the qualitative phase, 33 of the 100 patients participated in semi-structured interviews. ANALYSIS: Qualitative data was analyzed using the Sort & Sift, Think & Shift method. Integrated analysis included merged data displays of healthcare utilization data and patient descriptions of their care and genogram-type illustrations to enable variable-oriented analysis of structural support. We then examined patient narratives by two variables: life course and care elevation, to understand differences in the trajectories of six subsets of patients as identified by the quantitative data. KEY RESULTS: Three factors prompted patients to enroll in HaH: low attention from hospital staff during hospital stay; loneliness and isolation during hospital stay; and family encouragement to enroll. After discharge, social support within the home structure facilitated recovery during HaH. Conversely, HaH patients with limited support within the home were more likely to be readmitted. CONCLUSIONS: Structural social connectedness facilitates patient recovery in HaH. Before enrolling patients in HaH, clinicians should take an in-depth social history, including questions about social/familial roles, household responsibilities, and technology acceptance. Clinicians should engage formal and informal caregivers in these conversations early and communicate a clear picture of what caregivers should do to support the patient through recovery.

Adolescent sources of stress, stress levels, and associations between stress and changes in weight outcomes at the time of COVID-19 related school closure in March 2020.

Objective: Stress is associated with weight changes, yet how level and sources of stress relate to this association is poorly understood. This mixed methods study examined associations between adolescent stress at the COVID-19 pandemic onset and standardized BMI (BMIz) over a three-month period. Methods: Participants (N = 197, mean age 13.66 ± 1.43 years, 85% Hispanic, 56% female) were recruited from a charter school in Texas to participate in a healthy lifestyle intervention during physical education class. We calculated BMIz using height and weight measurements taken December 2019 and the week of COVID-19 school closures in March 2020. We measured stress in March 2020 with the 4-item Perceived Stress Scale. We ran a multiple linear regression model controlling for baseline BMIz (December 2019), age, sex, intervention condition, and assessed the interaction between baseline BMIz and PSS-4 score on BMIz change. Results: Overall, our sample had an average PSS-4 score of seven and mean BMIz decrease of 0.04 over the three-month period. We observed a significant interaction between PSS-4 score and baseline BMIz. At lower baseline BMIz scores, higher PSS-4 scores were associated with decreases in BMIz over time. There was no significant association at higher baseline BMIz scores. COVID-19 pandemic-related concerns and school performance were the two primary stressors reported. Conclusions: The relation between stress and weight changes differed based on starting weight status. Future interventions should consider the influence of external stressors on intervention adherence and outcomes.

Strongyloides stercoralis: Uncommon yet not to be missed cause of eosinophilia.

Strongyloides stercoralis is a soil-transmitted nematode that is estimated to infect millions of people per year worldwide. However, cases are less commonly seen in the United States. This report highlights the importance of when to include Strongyloides stercoralis in the differential diagnosis of patients presenting eosinophilia within the United States.

Creation of a medical procedure service in a tertiary medical center: Blueprint and procedural outcomes.

BACKGROUND: Medical Procedure Services (MPS) may represent a solution to the educational gap in procedural training among internal medicine residents and the unmet need for the clinical provision of non-urgent inpatient procedures. However, there is little guidance available to help launch an MPS. Furthermore, procedural outcomes from a newly initiated MPS, including those comparing trainees versus attending physicians, are lacking. OBJECTIVE: To describe the blueprint used in the design, implementation, and ongoing oversight of an MPS and to report its procedural outcomes. DESIGN, SETTINGS AND PARTICIPANTS: Vanderbilt University Medical Center (VUMC), Nashville, Tennessee. INTERVENTION: The launch of an MPS at a large tertiary academic hospital. MAIN OUTCOME AND MEASURES: 6,152 procedural consultations resulting in 5,320 attempted procedures over a four-and-a-half year period. RESULTS: The primary proceduralist was a supervised resident in 58.7% (3124 /5,320) and an attending in 41.3% (2,196/5,320) of procedures. The overall success rate was 91.1% (95% CI: 90.3-91.9%) and the major complication rate was 0.7% (95% CI: 0.5-1.0%). There was no difference in the mean number of attempts required to complete a procedure (1.6 vs 1.5 attempts, p=0.68) and the complication rates between supervised residents and attending proceduralists, respectively (20/3,124 vs 20/2,196, p=0.26). CONCLUSION: At a tertiary academic medical center, the implementation and maintenance of MPS is feasible, safe, and results in high rates of successful procedures performed by supervised residents. Procedures performed by supervised residents require comparable number of attempts for completion and carry similar risks as those performed alone by attendings.

Sport: A Holistic Approach to Lifestyle Medicine.

Sport represents a holistic health tool that unifies multiple pillars of lifestyle medicine. Sport can mitigate both the ongoing health disparities in communities that were present before COVID-19 and those exacerbated after COVID-19. The significance of this recommendation is highlighted by the impact sport participation has on creating healthy relationships, managing stress, and delivering physical activity among diverse populations. Importantly, sport can offer meaning and value to its participants, particularly when COVID-19 has limited people's ability for purposeful activity and social interaction. Clinicians are urged to consider the broad utility of sport for the prevention and treatment of unhealthy behaviors.

An old disease with a new twist: CNS and thyroid sarcoidosis presenting as subacute dementia.

Dementia in the elderly is extremely common and is often irreversible. When a patient presents with rapid cognitive decline, uncommon reversible etiologies should be investigated with the goal of restoring cognitive function.

A Multicenter Curricular Intervention to Address Resident Knowledge and Perceptions of Personal Finance.

OBJECTIVES: We evaluated internal medicine residents' confidence and knowledge of personal finance, perceptions of burnout, and relations between these issues before and after an educational intervention. METHODS: We surveyed internal medicine residents at two university-based training programs in 2018. We developed and implemented a curriculum at both sites, covering topics of budgeting, saving for retirement, investment options, and the costs of investing. Each site used the same content but different strategies for dissemination. One used a condensed-form lecture series (two 1-hour sessions) and the other used a microlecture series (four 30-minute sessions) series. Residents were resurveyed following the intervention for comparison. RESULTS: The preintervention survey response rate was 41.2% (122/296) and the postintervention response rate was 44.3% (120/271). Postintervention mean scores for personal finance knowledge improved for basic concepts (52.6% vs 39.4%, P < 0.001), mutual fund elements (30.8% vs 19.7%, P < 0.001), investment plans (68.5% vs. 49.2%, P < 0.001), and overall knowledge (50.1% vs 36.1%, P < 0.001). A significantly smaller proportion of residents reported feelings of burnout following the intervention (23.3% vs 36.9%, P = 0.022). CONCLUSIONS: Our findings show that residents want to learn about finances. Our brief educational intervention is a practical way to improve overall knowledge. Our intervention suggests that improving knowledge of finance may be associated with decreased feelings of burnout.

Identification of high resource utilizing patients on internal medicine hospital services.

In order to provide high quality, cost-efficient care, it is critical to understand drivers of the cost of care. Therefore, we sought to identify clinical variables associated with high utilization (cost) in patients admitted to medical services and to develop a robust model to identify high utilization patients. In this case-control analysis, cases were identified as the 200 most costly patients admitted to internal medicine/internal medicine subspecialty services using our institution's computerized clinical data warehouse over a 7-month time period (November 1, 2012-May 31, 2013). 400 patients admitted in the same time period were randomly selected to serve as controls. The mean cost for the highest utilization patients was $126,343, while that for randomly matched patients was $15,575. In a multivariable regression model, the following variables were associated with high utilization of resources: African American race, age 35-44, admission through the emergency department, primary service of hematology-oncology, a history of heart failure or paralysis, a diagnosis of HIV, cancer, collagen vascular diseases and/or coagulopathy, a reduced albumin, and/or an elevated creatinine. The in hospital mortality rate for high utilization patients was 19%, compared to 8% for controls (p=0.0002). A predictive model using 14 different readily available clinical variables predicted high utilization with an area under the curve of 0.85. The data suggest that high utilization patients share similar demographic and clinical features. We speculate that a predictive model using commonly known patient characteristics should be able to predict high utilization patients.

Next-generation sequencing identifies TGF-ß1-associated gene expression profiles in renal epithelial cells reiterated in human diabetic nephropathy.

Transforming growth factor-beta (TGF-ß1) is implicated in the onset and progression of renal fibrosis and diabetic nephropathy (DN), leading to a loss of epithelial characteristics of tubular cells. The transcriptional profile of renal tubular epithelial cells stimulated with TGF-ß1 was assessed using RNA-Seq, with 2027 differentially expressed genes identified. Promoter analysis of transcription factor binding sites in the TGF-ß1 responsive gene set predicted activation of multiple transcriptional networks, including NFκB. Comparison of RNA-Seq with microarray data from identical experimental conditions identified low abundance transcripts exclusive to RNA-Seq data. We compared these findings to human disease by analyzing transcriptomic data from renal biopsies of patients with DN versus control groups, identifying a shared subset of 179 regulated genes. ARK5, encoding an AMP-related kinase, and TGFBI - encoding transforming growth factor, beta-induced protein were induced by TGF-ß1 and also upregulated in human DN. Suppression of ARK5 attenuated fibrotic responses of renal epithelia to TGF-ß1 exposure; and silencing of TGFBI induced expression of the epithelial cell marker - E-cadherin. We identified low abundance transcripts in sequence data and validated expression levels of several transcripts (ANKRD56, ENTPD8) in tubular enriched kidney biopsies of DN patients versus living donors. In conclusion, we have defined a TGF-ß1-driven pro-fibrotic signal in renal epithelial cells that is also evident in the DN renal transcriptome.

Extracellular BMP-antagonist regulation in development and disease: tied up in knots.

Developmental processes are regulated by the bone morphogenetic protein (BMP) family of secreted molecules. BMPs bind to serine/threonine kinase receptors and signal through the canonical Smad pathway and other intracellular effectors. Integral to the control of BMPs is a diverse group of secreted BMP antagonists that bind to BMPs and prevent engagement with their cognate receptors. Tight temporospatial regulation of both BMP and BMP-antagonist expression provides an exquisite control system for developing tissues. Additional facets of BMP-antagonist biology, such as crosstalk with Wnt and Sonic hedgehog signaling during development, have been revealed in recent years. In addition, previously unappreciated roles for the BMP antagonists in kidney fibrosis and cancer have been elucidated. This review provides a description of BMP-antagonist biology, together with highlights of recent novel insights into the role of these antagonists in development, signal transduction and human disease.

Co-regulation of Gremlin and Notch signalling in diabetic nephropathy.

Diabetic nephropathy is currently the leading cause of end-stage renal disease worldwide, and occurs in approximately one third of all diabetic patients. The molecular pathogenesis of diabetic nephropathy has not been fully characterized and novel mediators and drivers of the disease are still being described. Previous data from our laboratory has identified the developmentally regulated gene Gremlin as a novel target implicated in diabetic nephropathy in vitro and in vivo. We used bioinformatic analysis to examine whether Gremlin gene sequence and structure could be used to identify other genes implicated in diabetic nephropathy. The Notch ligand Jagged1 and its downstream effector, hairy enhancer of split-1 (Hes1), were identified as genes with significant similarity to Gremlin in terms of promoter structure and predicted microRNA binding elements. This led us to discover that transforming growth factor-beta (TGFbeta1), a primary driver of cellular changes in the kidney during nephropathy, increased Gremlin, Jagged1 and Hes1 expression in human kidney epithelial cells. Elevated levels of Gremlin, Jagged1 and Hes1 were also detected in extracts from renal biopsies from diabetic nephropathy patients, but not in control living donors. In situ hybridization identified specific upregulation and co-expression of Gremlin, Jagged1 and Hes1 in the same tubuli of kidneys from diabetic nephropathy patients, but not controls. Finally, Notch pathway gene clustering showed that samples from diabetic nephropathy patients grouped together, distinct from both control living donors and patients with minimal change disease. Together, these data suggest that Notch pathway gene expression is elevated in diabetic nephropathy, co-incident with Gremlin, and may contribute to the pathogenesis of this disease.

Genomic differences between Candida glabrata and Saccharomyces cerevisiae around the MRPL28 and GCN3 loci.

We report the sequences of two genomic regions from the pathogenic yeast Candida glabrata and their comparison to Saccharomyces cerevisiae. A 3 kb region from C. glabrata was sequenced that contains homologues of the S. cerevisiae genes TFB3, MRPL28 and STP1. The equivalent region in S. cerevisiae includes a fourth gene, MFA1, coding for mating factor a. The absence of MFA1 is consistent with C. glabrata's asexual life cycle, although we cannot exclude the possibility that a-factor gene(s) are located somewhere else in its genome. We also report the sequence of a 16 kb region from C. glabrata that contains a five-gene cluster similar to S. cerevisiae chromosome XI (including GCN3) followed by a four-gene cluster similar to chromosome XV (including HIS3). A small-scale rearrangement of gene order has occurred in the chromosome XI-like section.
