Age of obesity onset affects subcutaneous adipose tissue cellularity differently in the abdominal and femoral region.

OBJECTIVE: We aimed to examine the effect of age of obesity onset, sex, and their interaction on abdominal and femoral subcutaneous adipose tissue (SAT) morphology (degree of adipocyte hyperplasia or hypertrophy). METHODS: In this cross-sectional study, we isolated adipocytes via collagenase digestion from abdominal and femoral SAT biopsies taken from male and female adults with childhood-onset obesity (CO; n = 8 males, n = 16 females) or adult-onset obesity (AO; n = 8 males, n = 13 females). Regional body composition was measured with dual-energy x-ray absorptiometry and a single-slice abdominal computed tomography scan. Mean adipocyte size was measured in abdominal and femoral SAT and was used to quantify morphology in android and gynoid subcutaneous fat, respectively. RESULTS: Abdominal SAT morphology was more hyperplastic in females with CO than females with AO (p = 0.004) but did not differ between males with CO and males with AO (p = 0.996). Conversely, femoral SAT morphology was more hypertrophic in males and females with CO than those with AO. CONCLUSIONS: Age of obesity onset appears to affect SAT morphology differently in the abdominal and femoral regions of male and female adults. Our findings challenge the notion that SAT is uniformly hyperplastic in CO and hypertrophic in AO.

Nutritional Support Best Practices in Pediatric Blood and Marrow Transplant Patients: An Integrative Review.

Nutrition is vital to the long-term survival of children undergoing blood and marrow transplantation (BMT), but there is no standardization on how to optimize the nutritional status of these patients. A literature search was performed to evaluate nutritional support approaches currently in practice for pediatric patients who are undergoing BMT. CINAHL, Embase, and Cochrane databases were searched for peer-reviewed articles evaluating nutritional interventions for BMT recipients aged 20 or younger. Nine articles published between 2019 and 2023 were found and reviewed. The nutritional support varied between enteral nutrition, parenteral nutrition, a combination of both, and prophylactic feeding tube placement. The post-transplant outcomes identified as associated with alterations in nutritional regimens included length of stay, date of platelet engraftment, incidence of acute graft-versus-host disease, infection rate, and overall survival. The use of any amount of enteral nutrition compared to parenteral alone was beneficial. Complications during BMT can potentially be decreased via prioritizing enteral nutrition over parenteral. The paucity of literature on this topic highlights an unmet need in the field. Future research should focus on ways to optimize the nutritional support of transplant recipients, including increasing the likelihood of enteral feeding tube placement and utilization.

Urodynamic insights: exploring the relationship between detrusor overactivity and pelvic organ prolapse in women with urge incontinence.

PURPOSE: Pelvic organ prolapse (POP) and overactive bladder (OAB) commonly affect the aging female population. We aimed to investigate the possible relationship between the two, as reflected by urodynamic studies. METHODS: A retrospective analysis was conducted on women who underwent urodynamic studies at a university-affiliated tertiary medical center from January 2018 to January 2021. Women presenting with urge incontinence and diagnosed with detrusor overactivity (DO) were included in the study. Based on the presence or absence of a modified POP-Q ≥ grade 2, these women were categorized into two groups. Data on general demographics, clinical symptoms, and urodynamic findings were extracted and compared using SPSS. RESULTS: During the study period, 949 urodynamic evaluations were performed. Of these, 303 (31.92%) reported urge incontinence. Out of this subset, 151 (49.83%) were diagnosed with DO. Within this group, 18 (11.9%) had POP, while 134 (88.1%) did not. The POP group had a notably higher incidence of prior vaginal hysterectomy and anterior colporrhaphy (p = 0.02 and p = 0.01, respectively). While most urodynamic parameters were similar between groups, there was a significant increase in hesitancy in the POP group (13 s vs 8 s, p = 0.03). There was a trend indicating a reduced median Q max (12 ml/s vs. 18 ml/s, p = 0.06) and an increased flow time (55 s vs 40 s, p = 0.08) in the POP group. CONCLUSION: The urodynamic profile of the POP group suggests an obstructive voiding pattern. Further longitudinal research is essential to fully understand the relationship between POP and OAB.

Cancer anorexia-cachexia syndrome is characterized by more than one inflammatory pathway.

BACKGROUND: The interdependence of cytokines and appetite-modifying hormones implicated in cancer anorexia-cachexia syndrome (CACS) remains unclear. This study aimed to regroup these cytokines and hormones into distinct inflammatory (or non-inflammatory) pathways and determine whether these pathways can classify patients with CACS phenotypes. METHODS: Clinical characteristics of 133 patients [61.7% male; mean age = 63.4 (SD: 13.1) years] with advanced cancer prior to oncology treatments were documented, including weight loss history. Patients completed the Functional Assessment of Anorexia-Cachexia Therapy (FAACT) questionnaire and Timed Up and Go test and had their sex-standardized skeletal muscle index (z-SMI) and fat mass index (z-FMI) derived using computed tomography scans. Their plasma levels of cytokines and appetite-modifying hormones were also determined. Date of death was recorded. Exploratory factor analysis (EFA) was used to regroup 15 cytokines and hormone into distinct inflammatory pathways (factors). For each patient, regression factor scores (RFS), which tell how strongly the patient associates with each factor, were derived. Two-step cluster analysis on the RFS was used to classify patients into groups. CACS phenotypes were correlated with RFS and compared between groups. Groups' survival was estimated using Kaplan-Meier analysis. RESULTS: Patients had low z-SMI (mean = -3.78 cm2/m2; SD: 8.88) and z-FMI (mean = 0.08 kg2/m2; SD: 56.25), and 62 (46.6%) had cachexia. EFA identified three factors: (F-1) IFN-γ, IL-1ß, Il-4, IL-6, IL-10, IL-12, TGFß1 (positive contribution), and IL-18 (negative); (F-2) IL-8, IL-18, MCP-1, TGFß1, TNF-α (positive), and ghrelin (negative); and (F-3) TRAIL and leptin (positive), and TGFß1 and adiponectin (negative). RFS-1 was associated with cachexia (P = 0.002); RFS-2, with higher CRP (P < 0.0001) and decreased physical function (P = 0.01); and RFS-3 with better appetite (P = 0.04), lower CRP (P = 0.002), higher z-SMI (P = 0.04) and z-FMI (P < 0.0001), and less cachexia characteristics (all P < 0.001). Four patient groups were identified with specific RFS clusters aligning with the CACS continuum from no cachexia to pre-cachexia, cachexia, and terminal cachexia. Compared to the other two groups, groups 1 and 2 had higher plasma levels of IL-18 and TRAIL. Group 1 also had lower inflammatory cytokines, adiponectin, and CRP compared to the other three groups. Group 3 had inflammatory cytokine levels similar to group 2, except for TNF-α and leptin which were lower. Group 4 had very high inflammatory cytokines, adiponectin, and CRP compared to the other 3 groups (all P < 0.0001). Groups 3 and 4 had worse cachexia characteristics (P < 0.05) and shorter survival (log rank: P = 0.0009) than the other two groups. CONCLUSIONS: This exploratory study identified three distinct pathways of inflammation, or lack thereof, characterizing different CACS phenotypes.

Implementation, Reach, and Effectiveness of the Direct Observation of Residents in Clinic Program.

BACKGROUND: Direct observation is important, yet medical residents are rarely observed. We implemented and evaluated a direct observation program in resident clinics to increase the frequency of observation and feedback and improve perceptions about direct observation. METHODS: We assigned faculty as observers in our resident clinics between June 2019 and February 2020. We surveyed residents and faculty before and after the program. Faculty completed a form for each observation performed. We analyzed surveys to examine changes in barriers, frequency and type of observations and feedback, and attitudes toward observation. The analytical sample included 38 and 37 pre- and postresident surveys, respectively, and 20 and 25 pre- and postfaculty surveys, respectively. RESULTS: Resident survey response rates were 32.3% (40/124) pre- and 30.7% (39/127) postintervention. Most residents (76% [pre], 86% [post], P = 0.258) reported being observed in at least one of the four areas: history, examination, counseling, or wrap-up. We received observation tracking forms on 68% of eligible residents. Observed history taking increased from 30% to 79% after the program (P = 0.0010). Survey response rates for faculty were 64.7% (22/34) pre- and 67.5% (25/37) postintervention. Fewer faculty reported time (80% [pre], 52% [post], P = 0.051) and competing demands (65% [pre], 52% [post], P = 0.380) as barriers postintervention. Fewer faculty postintervention viewed observation as a valuable teaching tool (100% [pre], 79% [post], P = 0.0534). All faculty who did not view observation as valuable were the least experienced. DISCUSSION: Assigning faculty as observers can increase observation, especially in history taking, though data suggest an increase in negative perceptions of observation by faculty.
