Food fortification with micronutrients is one of the cost-effective and sustainable methods to prevent micronutrient deficiencies at community level. The rice fortified with iron, folic acid, and vitamin B12 is being supplied through various social welfare schemes in India in a phased manner and planned to cover the entire country by March 2024. We have conducted a situational analysis to assess the rollout of fortified rice supplied through the Public Distribution System (PDS) and to evaluate the accessibility, availability, acceptability, and utilization of fortified rice by the beneficiaries of the PDS. This was a mixed-method, sequential exploratory study conducted in six districts from six different states of India that had begun distribution of fortified rice through PDS in pilot mode during 2020-2021. In each district, the district supply officer of the PDS, Food Corporation of India (FCI) or State Food Corporation (SFC) warehouse supervisor, and four Fair Price Shop (FPS) dealers were interviewed. Under each FPS, a minimum of seven beneficiary households were randomly selected and interviewed using a structured questionnaire. The in-depth interviews were conducted with different stakeholders using theme guides. All the interviewed stakeholders were aware about their roles and responsibilities and purpose to distribute fortified rice. There was a continuous supply of fortified rice (across all visited districts) to beneficiaries through a well-established system. Acceptability and compliance to intake of fortified rice was good with no reported gastrointestinal adverse outcomes following fortified rice intake. There was an efficient roll-out of fortified rice though PDS with a good compliance to intake of fortified rice. It is feasible to design and conduct a study to assess the impact of fortified rice on anemia and iron storage at the community level.

Abstract Background Semantic Web Technology (SWT) makes it possible to integrate and search the large volume of life science datasets in the public domain, as demonstrated by well-known linked data projects such as LODD, Bio2RDF, and Chem2Bio2RDF. Integration of these sets creates large networks of information. We have previously described a tool called WENDI for aggregating information pertaining to new chemical compounds, effectively creating evidence paths relating the compounds to genes, diseases and so on. In this paper we examine the utility of automatically inferring new compound-disease associations (and thus new links in the network) based on semantically marked-up versions of these evidence paths, rule-sets and inference engines. Results Through the implementation of a semantic inference algorithm, rule set, Semantic Web methods (RDF, OWL and SPARQL) and new interfaces, we have created a new tool called Chemogenomic Explorer that uses networks of ontologically annotated RDF statements along with deductive reasoning tools to infer new associations between the query structure and genes and diseases from WENDI results. The tool then permits interactive clustering and filtering of these evidence paths. Conclusions We present a new aggregate approach to inferring links between chemical compounds and diseases using semantic inference. This approach allows multiple evidence paths between compounds and diseases to be identified using a rule-set and semantically annotated data, and for these evidence paths to be clustered to show overall evidence linking the compound to a disease. We believe this is a powerful approach, because it allows compound-disease relationships to be ranked by the amount of evidence supporting them.

- Abstract
Study Objective: To evaluate operative complications and healthcare utilization in transgender patients on testosterone undergoing minimally invasive gender-affirming hysterectomy compared to control patients., Design: We performed a retrospective cohort study. Operative reports were used to gather information on intraoperative complications. We collected information on postoperative complications, electronic medical record (EMR) messages, phone calls, emergency department utilization, and clinic visits through a 90-day postoperative period. Healthcare utilization reasons were categorized as vaginal bleeding, pain, vaginal discharge, dysuria, urinary retention, bowel concern, incision concern, or other., Setting: Tertiary care academic medical center., Patients: Patients aged 18 to 55 who underwent a benign minimally invasive hysterectomy with or without oophorectomy performed between January 2014 and December 2022. The testosterone-using cohort consisted of patients who had a gender identity of male, transgender male, genderqueer, or nonbinary with documented testosterone use prior to surgery (n = 88). The control cohort consisted of patients who identified as female, genderqueer, or nonbinary with no documented testosterone use (n = 242)., Interventions: Not applicable., Measurements and Main Results: Patients using testosterone were younger, had a lower body mass index, lower American Society of Anesthesiologists class, and were more likely to be nulliparous. The median time patients used testosterone was 2.5 years (1.5-5.0). Patients on testosterone are at increased risk of intraoperative perineal lacerations requiring repair (RR 3.3, CI 95% [1.03-10.5]). A higher number of patients on testosterone reported vaginal bleeding via EMR message or phone call (RR 1.74 CI 95% [1.1-2.7]) compared to controls. No difference in reasons for emergency department visits was noted. The use of postoperative vaginal estrogen started at the postoperative visit was more frequent in the testosterone-using patients (7 [8.0%] vs 4 [1.7%], p = .01)., Conclusion: This study demonstrates that testosterone use preoperatively may increase risk of intraoperative vaginal laceration requiring repair. Testosterone use also correlates with increased reports of vaginal bleeding through EMR message, phone call, and clinic visit. These results contribute new evidence to include in preoperative counseling and support existing evidence surrounding the safety of gender-affirming hysterectomy., Competing Interests: Conflict of Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this article., (Copyright © 2024 AAGL.

- Abstract
Bubble contrast echocardiography is commonly used to diagnose pulmonary arteriovenous malformations (PAVMs) in single ventricle congenital heart disease (CHD), yet previous studies inconsistently report a correlation between bubble echoes and oxygenation. In this study, we sought to re-evaluate the correlation between bubble echoes and oxygenation by assessing total bilateral shunting and unilateral shunting. We conducted a single-center, retrospective study of patients with single ventricle CHD and previous Glenn palliation who underwent a cardiac catheterization and bubble echocardiogram during the same procedure from 2011 to 2020. Spearman's rank correlation was performed to examine the relationship between total bilateral shunting and measures of systemic oxygenation, as well as unilateral shunting and ipsilateral pulmonary vein oxygenation. For all patients (n = 72), total bilateral shunting moderately correlated with peripheral oxygen saturation (SpO
2 ) (rs = -0.44, p < 0.0001). For patients with Glenn/Kawashima circulation (n = 49), total bilateral shunting was moderately correlated (SpO2 : rs = -0.38, p < 0.01). In contrast, unilateral shunting did not correlate with ipsilateral pulmonary vein oxygenation for any vein measured ( p = 0.16- p > 0.99). In conclusion, the total burden of bilateral bubble shunting correlated with systemic oxygenation and may better reflect the total PAVM burden from all lung segments. Unilateral correlation may be adversely influenced by non-standardized approaches to pulmonary vein sampling.- Published

- Abstract
Background: The exact prevalence of feeding problems in children with cystic fibrosis (CF) is unknown. Pediatric feeding disorder (PFD) encompasses poor oral intake with associated medical, nutrition, psychosocial, or feeding skill dysfunction. We hypothesized that PFD is common in CF and aimed to categorize feeding dysfunction across various domains in children with CF., Methods: An observational cross-sectional study was conducted in children with CF. Data collected included anthropometrics, nutrition data (including need for tube feeding/enteral nutrition [EN] or high-energy beverages, dietary diversity), feeding skills (Pediatric version of the Eating Assessment tool [pEAT]), and psychosocial function (About Your Child's Eating questionnaire [AYCE] in children 2-17 years of age/Behavioral Pediatric Feeding Assessment Scale [BPFAS] in children 12-23 months of age). PFD was defined as poor oral intake with: (a) pEAT score > 5; and/or (b) AYCE or BPFAS score > 2 standard deviation of normative controls; and/or (c) nutrition dysfunction (body mass index/weight-for-length z score < -1 and/or preference of oral high energy beverages or dependence on EN and/or decreased dietary diversity)., Results: Of 103 children in the study, 62 (60.1%) had PFD, 7 children (6.8%) were malnourished, 10 needed EN (9.7%), and 30 (29.1%) needed oral high-energy beverages. Dietary diversity was decreased in 42 children (41.5%), 1 child had feeding skill dysfunction, and 11 (10.8%) met criteria for psychosocial dysfunction., Conclusion: Almost 2/3rd of children with CF have PFD and many have poor dietary diversity. A significant percentage of children rely on EN and oral supplements, but psychosocial dysfunction is less prevalent., Competing Interests: Dr Goday has served as a consultant for Shire-Takeda Pharmaceuticals. The remaining authors report no conflicts of interest., (Copyright © 2023 by European Society for European Society for Pediatric Gastroenterology, Hepatology, and Nutrition and North American Society for Pediatric Gastroenterology, Hepatology, and Nutrition.)

- Abstract
Objective: Posttraumatic stress symptoms (PTSS) have been associated with increased somatic symptom expression. Sleep concerns have been associated with PTSS and somatic symptoms. Previous research suggests that sleep affects multiple domains of functioning including comorbid psychological and physical health concerns. The current study examines whether perceived sleep quality or sleep efficiency/duration may be mediating the relationship between PTSS and somatic symptoms in a trauma-exposed sample., Method: The sample consisted of 864 students, recruited from a large Midwestern university and compensated with research participation credit. Data were collected online over approximately 39 months (October 2015 through January 2019), and the pertinent scales examined in this study included Pittsburgh Sleep Quality Index, Posttraumatic Stress Disorder Checklist for Diagnostic and Statistical Manual of Mental Disorders , fifth edition, and Screening for Somatoform Symptoms-7., Results: Of the 864 students, 668 participants identified as female (77.3%) and 540 identified as non-Hispanic White (62.5%), with an overall average age of 23.14 years ( SD = 6.64). Mediation analyses indicated that the overall model examining global sleep quality complaints as a mechanism of the relationship between PTSS and somatic symptoms was significant, F (3, 860) = 193.97, R ² = .40, p < .001, and that perceived sleep quality was found to be the only significant specific mediator (indirect effect = .21). Although females reported greater somatic severity, PTSS, and sleep concerns, models were significant, even after examining the influence of gender., Conclusions: Global sleep complaints are associated with both PTSS and somatic symptoms. Perceived sleep quality specifically mediated the relationship between PTSS and somatic symptoms, highlighting a potential intervention for improving physical health consequences in trauma-exposed individuals.

- Abstract
Background: A majority of older adults with cancer develop malnutrition; however, the implications of malnutrition among this vulnerable population are poorly understood. The goal of this study was to quantify the prevalence of nutrition related-symptoms and malnutrition among older adults with gastrointestinal (GI) malignancies and the association of malnutrition with geriatric assessment (GA) impairment, health-related quality of life (HRQoL), and health care utilization., Methods: We performed a cross-sectional study of older adults (≥60 years) who were referred to the GI Oncology clinic at the University of Alabama at Birmingham. Participants underwent the Cancer & Aging Resilience Evaluation survey that includes the abbreviated Patient-Generated Subjective Global Assessment of nutrition. Nutrition scores were dichotomized into normal (0-5) and malnourished (≥6), and multivariate analyses adjusted for demographics, cancer type, and cancer stage were used to examine associations with GA impairment, HRQoL, and health care utilization., Results: A total of 336 participants were included (men, 56.8%; women, 43.2%), with a mean age of 70 years (standard deviation, ±7.2 years) and colorectal cancer (33.6%) and pancreatic cancer (24.4%) being the most common diagnoses. Overall, 52.1% of participants were identified as malnourished. Malnutrition was associated with a higher prevalence of several GA impairments, including 1 or more falls (adjusted odds ratio [aOR], 2.1), instrumental activities of daily living impairment (aOR, 4.1), and frailty (aOR, 8.2). Malnutrition was also associated with impaired HRQoL domains; both physical (aOR, 8.7) and mental (aOR, 5.0), and prior hospitalizations (aOR, 2.2)., Conclusion: We found a high prevalence of malnutrition among older adults with GI malignancies that was associated with increased GA impairments, reduced HRQoL, and increased health care utilization., (© 2020 American Cancer Society.)

- Abstract
Telehealth is a potential solution to limited access to specialized services for children with autism spectrum disorder (ASD) in rural areas. We conducted a feasibility trial of parent training with children ages 3-8 with ASD and disruptive behavior from rural communities. Fourteen children (mean age 5.8 ± 1.7) from four telehealth sites enrolled. Thirteen families (92.9%) completed treatment, with 91.6% of core sessions attended. Therapists attained 98% fidelity to the manual and 93% of expected outcome measures were collected at week 24. Eleven of 14 (78.6%) participants were rated as much/very much improved. Parent training via telehealth was acceptable to parents and treatment could be delivered reliably by therapists. Preliminary efficacy findings suggests further study is justified.

- Abstract
Objective: We examine weight gain and metabolic consequences of risperidone monotherapy in children with autism spectrum disorder (ASD)., Method: This was a 24-week, multisite, randomized trial of risperidone only versus risperidone plus parent training in 124 children (mean age 6.9 ± 2.35 years; 105 boys and 19 girls) with ASD and serious behavioral problems. We monitored height, weight, waist circumference, and adverse effects during the trial. Fasting blood samples were obtained before treatment and at week 16., Results: In 97 children with a mean of 22.9 ± 2.8 weeks of risperidone exposure, there was a 5.4 ± 3.4 kg weight gain over 24 weeks (p < .0001); waist circumference increased from 60.7 ± 10.4 cm to 66.8 ± 11.3 cm (p < .0001). At baseline, 59 of 97 children (60.8%) were classified as having normal weight; by week 24, only 25 of 85 (29.4%) remained in that group. Growth curve analysis showed a significant change in body mass index (BMI) z scores from pretreatment to week 24 (p < .0001). This effect was significantly greater for children with reported increased appetite in the first 8 weeks. From before treatment to week 16, there were significant increases in glucose (p = .02), hemoglobin A1c (p = .01), insulin (p <.0001), homeostatic model assessment-insulin resistance (HOMA-IR; p < .001), alanine aminotransferase (p = .01), and leptin (p < .0001). Adiponectin declined (p = .003). At baseline, 7 children met conventional criteria for metabolic syndrome; by week 16, 12 additional children were so classified., Conclusion: Rapid weight gain with risperidone treatment may promote the cascade of biochemical indices associated with insulin resistance and metabolic syndrome. Appetite, weight, waist circumference, liver function tests, blood lipids, and glucose warrant monitoring.
