Computed tomography-based body composition profile as a screening tool for geriatric frailty detection.

OBJECTIVE: To assess prevalence of CT imaging-derived sarcopenia, osteoporosis, and visceral obesity in clinically frail and prefrail patients and determine their association with the diagnosis of frailty. MATERIALS AND METHODS: This cross-sectional study was constructed using our institution's pelvic trauma registry and ambulatory database registry. The study included all elderly pelvic trauma patients and ambulatory outpatients between May 2016 and March 2020 who had a comprehensive geriatric assessment and CT abdomen/pelvis within 1 year from the date of the assessment. Patients were dichotomized in prefrail or frail groups. The study excluded patients with history of metastatic disease or malignancy requiring chemotherapy. RESULTS: The study cohort consisted of 151 elderly female and 65 male patients. Each gender population was subdivided into frail (114 female [75%], 51 male [78%]) and prefrail (37 female [25%], 14 male [22%]) patients. CT-imaging-derived diagnosis of osteoporosis (odds ratio, 2.5; 95% CI: 1.2-5.5) and sarcopenia (odds ratio, 2.6; 95% CI: 1.2-5.6) were associated with frailty in females, but did not reach statistical significance in males. BMI and subcutaneous adipose tissue at L3 level were statistically lower in the frail male group compared to the prefrail group. BMI showed strong correlation with the subcutaneous area at the L3 level in both genders (Spearman's coefficient of 0.8, p < 0.001). Hypoalbuminemia and visceral obesity were not associated with frailty in either gender. CONCLUSION: This proof-of-concept study demonstrates the feasibility of using CT-derived body-composition parameters as a screening tool for frailty, which can offer an opportunity for early medical intervention.

Machine Learning-Augmented Propensity Score-Adjusted Multilevel Mixed Effects Panel Analysis of Hands-On Cooking and Nutrition Education versus Traditional Curriculum for Medical Students as Preventive Cardiology: Multisite Cohort Study of 3,248 Trainees over 5 Years.

BACKGROUND: Cardiovascular disease (CVD) annually claims more lives and costs more dollars than any other disease globally amid widening health disparities, despite the known significant reductions in this burden by low cost dietary changes. The world's first medical school-based teaching kitchen therefore launched CHOP-Medical Students as the largest known multisite cohort study of hands-on cooking and nutrition education versus traditional curriculum for medical students. METHODS: This analysis provides a novel integration of artificial intelligence-based machine learning (ML) with causal inference statistics. 43 ML automated algorithms were tested, with the top performer compared to triply robust propensity score-adjusted multilevel mixed effects regression panel analysis of longitudinal data. Inverse-variance weighted fixed effects meta-analysis pooled the individual estimates for competencies. RESULTS: 3,248 unique medical trainees met study criteria from 20 medical schools nationally from August 1, 2012, to June 26, 2017, generating 4,026 completed validated surveys. ML analysis produced similar results to the causal inference statistics based on root mean squared error and accuracy. Hands-on cooking and nutrition education compared to traditional medical school curriculum significantly improved student competencies (OR 2.14, 95% CI 2.00-2.28, p < 0.001) and MedDiet adherence (OR 1.40, 95% CI 1.07-1.84, p = 0.015), while reducing trainees' soft drink consumption (OR 0.56, 95% CI 0.37-0.85, p = 0.007). Overall improved competencies were demonstrated from the initial study site through the scale-up of the intervention to 10 sites nationally (p < 0.001). DISCUSSION: This study provides the first machine learning-augmented causal inference analysis of a multisite cohort showing hands-on cooking and nutrition education for medical trainees improves their competencies counseling patients on nutrition, while improving students' own diets. This study suggests that the public health and medical sectors can unite population health management and precision medicine for a sustainable model of next-generation health systems providing effective, equitable, accessible care beginning with reversing the CVD epidemic.

Peripheral primitive neuroendocrine tumor of the chest wall-A case report with pathological correlation.

Primitive neuroectodermal tumor is a high-grade malignant tumor originating from the neural crest and neuroectoderm, which can be subdivided into central and peripheral categories. Peripheral primitive neuroectodermal tumor is thought to be identical to Ewing's sarcoma, and falls under a broader category of Ewing's sarcoma family of tumors. Very rarely, it may present without osseous involvement, known as extraosseous Ewing's sarcoma. Here we present a case of a 38-year-old woman, who presented with several-month history of a slow-growing chest wall mass, initially thought to be a breast mass. The mass was diagnosed as extraosseous Ewing's sarcoma upon tissue biopsy. The patient was started on a dose-intensified neoadjuvant therapy, based on protocol from pediatric population given rarity of this tumor in the adult population. While the patient was initially planned for surgical resection, the tumor showed excellent response to chemotherapy on follow-up imaging, and radiation therapy was elected in lieu of resection.

Cardiovascular risk factors among women with self-reported infertility.

BACKGROUND: Amongst women with certain types of ovulatory disorder infertility, the studies are conflicting whether there is an increased risk of long-term cardiovascular disease risk. This paper evaluates the associations of several CVD risk factors among Framingham women with self-reported infertility. METHODS: Women who completed the Framingham Heart Study Third Generation and Omni Cohort 2 Exam 2 (2008-2011), and reported on past history of infertility and current cardiovascular disease status were included in this cross-sectional study. Directly measured CVD risk factors were: resting blood pressure, fasting lipid levels, fasting blood glucose, waist circumference, and body mass index (BMI). Multivariable models adjusted for age, smoking, physical activity, and cohort. Generalized estimating equations adjusted for family correlations. We performed sensitivity analyses to determine whether the association between infertility and CVD risk factors is modified by menopausal status and menstrual cycle length. RESULTS: Comparing women who self-reported infertility to those who did not, there was an average increase in BMI (ß = 1.03 kg/m2, 95% CI: 0.18, 1.89), waist circumference (ß = 3.08 in., 95% CI: 1.06, 5.09), triglycerides (ß = 4.47 mg/dl, 95% CI:-1.54, 10.49), and a decrease in HDL cholesterol (ß = -1.60 mg/dl, 95% CI: -3.76, 0.56). We estimated that infertile premenopausal women have an increased odds of obesity (BMI ≥ 30 kg/m2) (OR = 1.56, 95% CI: 1.11, 4.49) and diabetes (OR = 1.96, 95% CI: 0.86, 4.49). CONCLUSIONS: BMI and waist circumference were the most strongly correlated CVD risk factors amongst women reporting a history of infertility.

Intravenous Iron Sucrose for Children With Iron Deficiency Anemia.

Iron deficiency anemia (IDA) is the most common nutritional deficiency in children. Most children with IDA are treated with oral iron preparations. However, intravenous (IV) iron is an alternative for children with severe IDA who have difficulty in adhering to or absorbing oral iron. We sought to describe the safety and effectiveness of IV iron sucrose for treatment of IDA in children. Pharmacy records of children who received IV iron sucrose at a children's hospital between 2004 and 2014 were reviewed. Laboratory markers of anemia and iron studies were obtained and preinfusion and postinfusion values were compared. Records were also reviewed for adverse reactions. A total of 142 patients received IV iron sucrose over 10 years. The mean age was 11 years, 9 months. One patient of 142 developed cough and wheezing during the infusion. No other adverse events were found. IV iron sucrose resulted in a statistically significant and clinically meaningful increase in hemoglobin, mean corpuscular volume, serum iron, ferritin, and % iron saturation, with a corresponding decrease in total iron binding capacity. The use of IV iron sucrose in pediatric patients with IDA is safe and leads to a moderate increase in hemoglobin and substantial improvement in iron studies.

Prenatal Exposure to Endocrine Disruptors: A Developmental Etiology for Polycystic Ovary Syndrome.

Polycystic ovary syndrome (PCOS) is one of the most common and complex endocrinopathies among reproductive-age women. Polycystic ovary syndrome is characterized by symptomatology of oligomenorrhea and androgen excess, with or without presence of polycystic ovarian morphology. The etiology of PCOS is multifactorial, including genetic and environmental components. It has been previously established that prenatal androgen exposure results in a PCOS phenotype in experimental animal models and epidemiologic human studies. Investigators hypothesize that prenatal exposure to endocrine-disrupting chemicals (EDCs) may contribute to PCOS development. This review examines the emerging research investigating prenatal exposure to 3 major classes of EDCs-bisphenol A (BPA), phthalates, and androgenic EDCs-and the development of PCOS and/or PCOS-related abnormalities in humans and animal models. Highlights of this review are as follows: (1) In rodent studies, maternal BPA exposure alters postnatal development and sexual maturation;, (2) gestational exposure to dibutyl phthalate and di(2-ethylhexyl)phthalate results in polycystic ovaries and a hormonal profile similar to PCOS; and (3) androgenic EDCs, nicotine and 3,4,4'-trichlorocarbanilide, create a hyperandrogenic fetal environment and may pose a potential concern. In summary, prenatal exposure to EDCs may contribute to the altered fetal programming hypothesis and explain the significant variability in severity and presentation.

Cosmetics use and age at menopause: is there a connection?

Cosmetics contain a vast number of chemicals, most of which are not under the regulatory purview of the Food and Drug Administration. Only a few of these chemicals have been evaluated for potential deleterious health impact: parabens, phthalates, polycyclic aromatic hydrocarbons, and siloxanes. A review of the ingredients in the best-selling and top-rated products of the top beauty brands in the world, as well as a review of highlighted chemicals by nonprofit environmental organizations, reveals 11 chemicals and chemical families of concern: butylated hydroxyanisole/butylated hydroxytoluene, coal tar dyes, diethanolamine, formaldehyde-releasing preservatives, parabens, phthalates, 1,4-dioxane, polycyclic aromatic hydrocarbons, siloxanes, talc/asbestos, and triclosan. Age at menopause can be affected by a variety of mechanisms, including endocrine disruption, failure of DNA repair, oxidative stress, shortened telomere length, and ovarian toxicity. There is a lack of available studies to make a conclusion regarding cosmetics use and age at menopause. What little data there are suggest that future studies are warranted. Women with chronic and consistent use of cosmetics across their lifespan may be a population of concern. More research is required to better elucidate the relationship and time windows of vulnerability and the effects of mixtures and combinations of products on ovarian health.

The Longitudinal Impact of Parent Distress and Behavior on Functional Outcomes Among Youth With Chronic Pain.

UNLABELLED: Accumulating evidence supports the concurrent association between parent distress and behavior and child functioning in the context of chronic pain, with existing longitudinal studies limited to a pediatric surgical context that identify parent catastrophizing as influential. In this study, we examined how parent factors assessed at a multidisciplinary pediatric pain clinic evaluation affect child psychological and functional outcomes over time. A cohort of 195 patients with chronic pain (ages 8-17 years) and their parents who presented for a multidisciplinary evaluation completed measures at baseline and at 4-month follow-up. Patients completed measures of pain catastrophizing, pain-related fear and avoidance, generalized anxiety, depressive symptoms, and functional disability. Parents completed measures of pain catastrophizing, pain-related fear and avoidance, and protective responses to child pain. Parent-reported child school functioning was also collected. Parent distress and behavior was concurrently associated with child distress and functioning at evaluation. After controlling for baseline child functioning, baseline parent avoidance and protective behavior emerged as significant predictors of child functioning at 4-month follow-up. Parent distress and behavior influence child distress and functioning over time and these findings identify key parent domains to target in the context of a child's pain treatment. PERSPECTIVE: Parent behavior, specifically avoidance and protective responses, influence child distress and functioning over time. Child pain treatment interventions should include influential parent factors to ensure successful outcomes.

Clinical vignettes and global health considerations of infertility care in under-resourced patients.

The ability to receive standard of care for a diagnosis of infertility is a factor of one's financial state and educational level, which are often correlated. Providing infertility care in an under-resourced tertiary care environment provides challenges but also opportunities for unique successes in creating a family. Among the under-represented populations are recent immigrants and refugees. Challenges arise when the infertility treatment is futile or when the standard of care is inaccessible due to cost and scheduling. Unique accomplishments are noted when families are built and hope is restored for couples fleeing from genocide and war-inflicted countries. This article will highlight two clinical vignettes from the Division of Reproductive Endocrinology and Infertility clinic at Boston University School of Medicine/Boston Medical Center. Thereafter, the article will summarize the barriers to care in the United States among those with low socioeconomic status, with non-dominant racial status (non-Caucasian), and with refugee status. All identifiers have been removed and names altered in the patient vignettes.

Perspectives on the clinical significance of functional pain syndromes in children.

Functional pain syndromes (FPS) characterize a subset of individuals who experience pain and related symptoms and disability without clear structural or disease etiology. In the pediatric population, FPS hold high clinical importance due to significant prevalence rates and potential to persist into adulthood. Although extensive research has been executed to disambiguate FPS, the syndromes that fall within its spectrum remain conceptually complex and sometimes ill-defined. This paper provides an overview of available research on the classification and multifaceted etiology of FPS in youth and their effects on interpersonal, psychological, and familial function. Vital aspects of a successful multidisciplinary approach to treating this population are described; however, it is evident that future research requires more longitudinal studies.
