RESUMO
In this randomized pilot study, we examined the effects of yoga intervention on axial and peripheral bone mineral density (BMD), disordered eating cognitions, anxiety, and depression in adolescent girls with anorexia nervosa (AN). Fifteen young women aged 13-18 years with AN or atypical AN were randomized to either a Yoga group (n = 7), including twice-weekly yoga for 24 weeks plus standard outpatient care, or Non-Yoga group (n = 8), who received standard outpatient care alone. Data from anthropometrics, mental health and eating behavior questionnaires, dual-energy x-ray absorptiometry, and peripheral quantitative computed tomography measurements were obtained at baseline and 6 months. The adjunct of yoga to standard treatment resulted in statistically significant improvement of axial BMD, depression, and disordered eating cognitions in comparison to the Non-Yoga group. In conclusion, a gentle yoga intervention may be beneficial for improving bone and mental health in adolescent females with AN.

OBJECTIVES/HYPOTHESIS: Veterans have an increasing prevalence of obstructive sleep apnea (OSA) and high levels of intolerance to positive airway pressure (PAP). The hypoglossal nerve stimulator (HNS) is a promising alternative surgical treatment for OSA in these patients, many of whom suffer from mental health conditions such as post-traumatic stress disorder (PTSD) that may negatively affect their ability to use PAP. Our aims were: 1) to assess postoperative changes in OSA severity and sleepiness in a veteran only population after HNS; 2) to compare postoperative changes in OSA severity, sleepiness and HNS adherence between veterans with and without PTSD; and 3) to compare HNS adherence in our population to HNS adherence in the current literature as well as published PAP adherence data. STUDY DESIGN: Retrospective and prospective case series. METHODS: Clinical data on consecutive patients undergoing HNS in a Veterans Affairs hospital were examined for demographic data as well as medical, sleep, and mental health comorbidities. The overall cohort as well as subsets of patients with and without PTSD were examined for postoperative changes in OSA severity (apnea hypopnea index [AHI], lowest oxygen saturation (LSAT]), and sleepiness (Epworth sleepiness scale [ESS]), as well as for device adherence. PTSD and depression symptomatology were measured using the PTSD Checklist 5 (PCL-5) and Patient Health Questionnaire 9 (PHQ-9). RESULTS: Forty-six veterans were included. Forty-four patients were male (95.6%), 45 were white (97.8%), and the mean age was 61.3 years. Twenty-six patients met PCL-5 criteria for PTSD and 17 did not. OSA severity and sleepiness improved significantly in the overall cohort after HNS; median (IQR) AHI decreased from 39.2 (24.0, 63.0) to 7.4 (1.2, 20.8) events/hour (P < .0001), mean LSAT increased from 81% to 88% (P < .0001) and mean ESS decreased from 10.9 to 6.7 (P < .0001). These improvements were similar between patients with and without PTSD (P = .434-.918). Overall device adherence was 6.1 hours/night for the overall cohort and was not significantly different between patients with and without PTSD (P = .992). CONCLUSIONS: HNS is an efficacious therapy in a veteran population, providing patients with significant improvements in OSA severity and sleepiness. Veterans with and without PTSD benefited similarly from HNS when comparing improvements in sleep apnea severity and sleepiness as well as device usage. Adherence was similar to previously published HNS adherence data and better than PAP adherence reported in the literature. LEVEL OF EVIDENCE: 4 Laryngoscope, 131:S1-S11, 2021.

OBJECTIVES: The hypoglossal nerve stimulator (HNS) is an effective treatment for obstructive sleep apnea (OSA) in a relatively healthy subset of the population. Our aim was to determine the efficacy of HNS in a veteran population with a high incidence of chronic disease and mental health disorders. Our secondary aim was to compare subjective outcomes and adherence between veterans with and without mental health disorders. METHODS: We included all patients who underwent HNS at our institution to date. Veterans were divided into two groups based on whether or not they carried a diagnosis of anxiety, depression, and/or post-traumatic stress disorder. Demographics, comorbidities, previous OSA treatments, adverse events, and adherence to therapy were recorded. Baseline and treatment outcome data were collected and analyzed including polysomnographic parameters, Epworth sleepiness scale score (ESS), and body mass index. RESULTS: Thirty-one patients were identified: 93.5% male, median age = 63.0 years. Median apnea hypopnea index (AHI) decreased from 30.0 to 3.0 events/hour (P < .001) and median ESS dropped from 11.0 to 6.5 (P < .001). There was no difference between groups with regard to change in AHI or ESS (P = .31 and .61). Twenty-six (89.7%) patients achieved surgical success (decrease in AHI > 50% and AHI < 20 events/hour) and 21 (72.4%) had AHI < 5 events/hour. The mean device usage was 5.4 hours/night which was not significantly different between groups (P = .55). CONCLUSION: Our cohort exhibited similar declines in AHI and ESS compared to published studies with adequate adherence to HNS. There were no significant differences in ESS or adherence to therapy between veterans with and without mental health disorders. LEVEL OF EVIDENCE: 4 Laryngoscope, 130:2275-2280, 2020.

OBJECTIVE: This retrospective cohort study examined whether bariatric surgery is associated with reduced risk of breast cancer among pre- and postmenopausal women. BACKGROUND: Obesity is associated with increased risk of breast cancer, but the impact of weight loss on breast cancer risk has been difficult to quantify. METHODS: The cohort included obese (body mass index ≥35âkg/m) patients enrolled in an integrated health care delivery system between 2005 and 2012 (with follow-up through 2014). Female bariatric surgery patients (N = 17,998) were matched on body mass index, age, study site, and comorbidity index to 53,889 women with no bariatric surgery. Kaplan-Meier curves and Cox proportional hazards models were used to examine incident breast cancer up to 10 years after bariatric surgery. Pre- and postmenopausal women were examined separately, and further classified by estrogen receptor (ER) status. RESULTS: The analysis included 301 premenopausal and 399 postmenopausal breast cancer cases. In multivariable adjusted models, bariatric surgery was associated with a reduced risk of both premenopausal (HR = 0.72, 95% CI, 0.54-0.94) and postmenopausal (HR = 0.55, 95% CI, 0.42-0.72) breast cancer. Among premenopausal women, the effect of bariatric surgery was more pronounced among ER-negative cases (HR = 0.36, 95% CI, 0.16-0.79). Among postmenopausal women, the effect was more pronounced in ER-positive cases (HR = 0.52, 95% CI, 0.39-0.70). CONCLUSIONS: Bariatric surgery was associated with a reduced risk of breast cancer among severely obese women. These findings have significant public health relevance because the prevalence of obesity continues to rise, and few modifiable breast cancer risk factors have been identified, especially for premenopausal women.

BACKGROUND: Vitamin D (vD) deficiency in pregnancy is a global health problem and the amount of vD supplementation to prevent vD deficiency is controversial. OBJECTIVE: The objective of the study was to determine effectiveness and safety of prenatal 2000 IU and 4000 IU/d compared with 400 IU/d vD3 supplementation in a randomized controlled trial in population in which vD deficiency is endemic. DESIGN/METHODS: Arab women were randomized at 12-16 weeks of gestation to 400, 2000, and 4000 IU/d vD3, which were continued to delivery. Serum 25-hydroxyvitamin D [25(OH)D] concentrations were measured during pregnancy and at delivery. The primary outcome was the maternal and cord blood 25(OH)D, and the secondary outcomes were the achievement of sufficient serum 25(OH)D of 32 ng/mL or greater (≥80 nmol/L) at delivery. SETTING: The locations were primary care and tertiary perinatal care centers. RESULTS: Of 192 enrolled, 162 (84%) continued to delivery. Mean serum 25(OH)D of 8.2 ng/mL (20.5 nmol/L) at enrollment was low. Mean serum 25(OH)D concentrations at delivery and in cord blood were significantly higher in the 2000 and 4000 IU than the 400 IU/d group (P < .001) and was highest in the 4000 IU/d group. The percent who achieved 25(OH)D greater than 32 ng/mL and greater than 20 ng/mL concentrations in mothers and infants was highest in 4000 IU/d group. Safety measurements were similar by group and no adverse event related to vD supplementation. CONCLUSIONS: Vitamin D supplementation of 2000 and 4000 IU/d appeared safe in pregnancy, and 4000 IU/d was most effective in optimizing serum 25(OH)D concentrations in mothers and their infants. These findings could apply to other populations in which vD deficiency is endemic.

This fMRI study investigated the development of language lateralization in left- and righthanded children between 5 and 18 years of age. Twenty-seven left-handed children (17 boys, 10 girls) and 54 age- and gender-matched right-handed children were included. We used functional MRI at 3T and a verb generation task to measure hemispheric language dominance based on either frontal or temporo-parietal regions of interest (ROIs) defined for the entire group and applied on an individual basis. Based on the frontal ROI, in the left-handed group, 23 participants (85%) demonstrated left-hemispheric language lateralization, 3 (11%) demonstrated symmetric activation, and 1 (4%) demonstrated right-hemispheric lateralization. In contrast, 50 (93%) of the right-handed children showed left-hemispheric lateralization and 3 (6%) demonstrated a symmetric activation pattern, while one (2%) demonstrated a right-hemispheric lateralization. The corresponding values for the temporo-parietal ROI for the left-handed children were 18 (67%) left-dominant, 6 (22%) symmetric, 3 (11%) right-dominant and for the right-handed children 49 (91%), 4 (7%), 1 (2%), respectively. Left-hemispheric language lateralization increased with age in both groups but somewhat different lateralization trajectories were observed in girls when compared to boys. The incidence of atypical language lateralization in left-handed children in this study was similar to that reported in adults. We also found similar rates of increase in left-hemispheric language lateralization with age between groups (i.e., independent of handedness) indicating the presence of similar mechanisms for language lateralization in left- and right-handed children.

PURPOSE: To use functional MRI (fMRI) methods to visualize a network of auditory and language-processing brain regions associated with processing an aurally-presented story. We compare a passive listening (PL) story paradigm to an active-response (AR) version including online performance monitoring and a sparse acquisition technique. MATERIALS AND METHODS: Twenty children (ages 11-13 years) completed PL and AR story processing tasks. The PL version presented alternating 30-second blocks of stories and tones; the AR version presented story segments, comprehension questions, and 5-second tone sequences, with fMRI acquisitions between stimuli. fMRI data was analyzed using a general linear model approach and paired t-test identifying significant group activation. RESULTS: Both tasks showed activation in the primary auditory cortex, superior temporal gyrus bilaterally, and left inferior frontal gyrus (IFG). The AR task demonstrated more extensive activation, including the dorsolateral prefrontal cortex and anterior/posterior cingulate cortex. Comparison of effect size in each paradigm showed a larger effect for the AR paradigm in a left inferior frontal region-of-interest (ROI). CONCLUSION: Activation patterns for story processing in children are similar in PL and AR tasks. Increases in extent and magnitude of activation in the AR task are likely associated with memory and attention resources engaged across acquisition intervals.
