Identifying the Prevalence of underdiagnosed Obstructive Sleep Apnea (OSA) in the Primary Care Population via Targeted Screening Measures
Introduction: Obstructive sleep apnea (OSA) is a condition with detrimental health consequences, yet over 75% of OSA cases remain undiagnosed in the United States. This study aimed to determine the efficacy of using targeted screening measures to determine the prevalence of undiagnosed OSA in a primary care population.
Methods: This prospective pilot study utilized a primary care population from Thomas Jefferson University’s family medicine department. Participants were selected using three risk criteria for OSA from STOP-BANG identifiable from their EMR records (BMI \u3e35, age over 50, and hypertension). After screening out patients previously diagnosed with OSA, patients were called and further screened with the entire STOP-BANG questionnaire; Patients who scored \u3e 6/8 were referred for sleep study testing.
Results: Of the 112 patients meeting the three initial criteria, 5 were excluded for having previously undocumented OSA diagnoses, and 81 were unable to be contacted or not interested. Of the 31 remaining participants, 11 patients had a STOP-BANG score \u3e6 (35%); 3 of these patients (27%) were diagnosed with OSA after going in for a sleep study (100%).
Discussion: The main obstacle in our pilot to date is low patient contact and participation. However, all of the patients who qualified for and completed sleep study testing using our screening algorithm were effectively diagnosed with OSA. We will continue to screen more patients in the upcoming months and test methodologies to increase patient participation
Primary Care Obstructive Sleep Apnea Screening (PCOSA)
Introduction: Obstructive sleep apnea (OSA) is a largely underdiagnosed disorder of upper airway collapse during sleep. Primary care providers do not routinely screen for OSA. This project aims to determine the yield of using the STOP-BANG questionnaire to identify previously undiagnosed OSA in a primary care population.
Methods: This prospective quality improvement pilot project included 181 patients of the Jefferson Department of Family Medicine identified as high-risk for OSA based on 3 EMR-based search criteria taken from STOP-BANG: hypertension, age \u3e50 years, and BMI \u3e35 kg/m2. We attempted contact with patients by mail, followed by up to 3 weekly telephone calls to verbally screen patients with the full STOP-BANG questionnaire. A score of \u3e6 was considered high-risk for OSA. High risk patients were referred for sleep study testing.
Results: From the initial 181 patients, 71 were excluded due to a prior OSA diagnosis; 3 were excluded for various other reasons; and 53 could not be reached. Of those reached, 28 patients refused participation, and 15 patients had a low-risk STOP-BANG score \u3c6. The remaining 11 patients had a high-risk STOP-BANG score \u3e6 and were referred for sleep study testing. While data collection is ongoing, all 3 patients (100%) who completed sleep studies have been newly diagnosed with OSA.
Discussion: Preliminary results confirm utility of the STOP-BANG questionnaire to identify patients at high risk for OSA. The main limitation in our pilot project was difficulty contacting patients. We are adding alternate forms of communication (email, outreach at upcoming patient visits)
Association of herd BRSV and BHV-1 seroprevalence with respiratory disease and reproductive performance in adult dairy cattle
<p>Abstract</p> <p>Background</p> <p>The aim of this study was to detect the associations between bovine herpesvirus 1 (BHV-1) status of a herd and respiratory disease (BRD) occurrence and reproductive performance in pregnant heifers and cows. The association between management-related factors and higher BRD occurrence was also estimated.</p> <p>Methods</p> <p>Serum samples, collected from cows and youngstock from 103 dairy cattle herds, were analyzed for antibodies against BHV-1, bovine respiratory syncytial virus (BRSV), bovine viral diarrhoea virus (BVDV), and <it>Mycoplasma bovis</it>. A questionnaire was used to collect data concerning herd management factors and reproductive performance, as well as the occurrence of clinical signs of respiratory disease in the last two years, as evaluated by the veterinarian or farm manager. Multiple correspondence analysis (MCA) and logistic regression analysis were performed to identify and quantify the risk factors.</p> <p>Results</p> <p>A low to moderate prevalence (1-49%) of BRSV antibodies among youngstock was associated with a high occurrence of respiratory disease (OR = 6.2, p = 0.010) in cows and in-calf heifers. Employees of the farm may participate in the spread of such disease. Larger herd size, loose-housing of cows, housing youngstock separately from cows until pregnancy, and purchasing new animals were factors possibly related to a high occurrence of respiratory disease symptoms in pregnant heifers and cows. The highest risk of abortions (> 1.3%) and increased insemination index (number of inseminations per pregnancy) (> 1.9) occurred in herds with a moderate prevalence of BHV-1 antibodies (1-49%) in cows.</p> <p>Conclusions</p> <p>BHV-1 was not associated with acute respiratory disease in adult dairy cattle, however was significantly related to reproductive performance. BRSV possesses the main role in respiratory disease complex in adult dairy cattle.</p

Gene–diet interactions on metabolic disease-related outcomes in Southeast Asian populations: a systematic review
Diabetes and obesity are chronic diseases that are a burden to low- and middle-income countries. We conducted this systematic review to understand gene–diet interactions affecting the Southeast Asian population’s risk of obesity and diabetes. The literature search was performed on Google Scholar and MEDLINE (PubMed) search engines independently by four reviewers who evaluated the eligibility of articles based on inclusion criteria. Out of 19,031 articles, 20 articles examining gene–diet interactions on obesity and/or diabetes-related traits met the inclusion criteria. Three (Malaysia, Indonesia, and Singapore) out of eleven Association of Southeast Asian Nations (ASEAN) countries have conducted studies on gene–diet interactions on obesity and diabetes. From the 20 selected articles, the most common interactions were observed between macronutrients and genetic risk score (GRS) on metabolic disease-related traits in the Malay, Chinese, and Indian ethnicities. Overall, we identified 29 significant gene–diet interactions in the Southeast Asian population. The results of this systematic review demonstrate ethnic-specific gene–nutrient interactions on metabolic-disease-related traits in the Southeast Asian population. This is the first systematic review to explore gene–diet interactions on obesity and diabetes in the Southeast Asian population and further research using larger sample sizes is required for better understanding and framing nutrigenetic approaches for personalized nutrition

BRAFV600E mutation is highly prevalent in thyroid carcinomas in the young population in Fukushima: a different oncogenic profile from Chernobyl
After the accident at the Fukushima Daiichi Nuclear Power Plant, the thyroid ultrasound screening program for children aged 0-18 at the time of the accident was started from October 2011. The prevalence of thyroid carcinomas in that population has appeared to be very high (84 cases per 296,253). To clarify the pathogenesis, we investigated the presence of driver mutations in these tumours. 61 classic papillary thyroid carcinomas (PTCs), two follicular variant PTCs, four cribriform-morular variant PTCs and one poorly-differentiated thyroid carcinoma were analysed. We detected BRAF V600E in 43 cases (63.2%), RET/PTC1 in six (8.8%), RET/PTC3 in one (1.5%) and ETV6/NTRK3 in four (5.9%). Among classic and follicular variant PTCs, BRAF V600E was significantly associated with the smaller size. The genetic pattern was completely different from post-Chernobyl PTCs, suggesting non-radiogenic etiology of these cancers. This is the first study demonstrating the oncogene profile in the thyroid cancers discovered by large mass screening, which probably reflects genetic status of all sporadic and latent tumours in the young Japanese population. It is assumed that BRAF V600E may not confer growth advantage on paediatric PTCs, and many of these cases grow slowly, suggesting that additional factors may be important for tumour progression in paediatric PTCs

State of the Art Review: Emerging Therapies: The Use of Insulin Sensitizers in the Treatment of Adolescents with Polycystic Ovary Syndrome (PCOS)
PCOS, a heterogeneous disorder characterized by cystic ovarian morphology, androgen excess, and/or irregular periods, emerges during or shortly after puberty. Peri- and post-pubertal obesity, insulin resistance and consequent hyperinsulinemia are highly prevalent co-morbidities of PCOS and promote an ongoing state of excess androgen. Given the relationship of insulin to androgen excess, reduction of insulin secretion and/or improvement of its action at target tissues offer the possibility of improving the physical stigmata of androgen excess by correction of the reproductive dysfunction and preventing metabolic derangements from becoming entrenched. While lifestyle changes that concentrate on behavioral, dietary and exercise regimens should be considered as first line therapy for weight reduction and normalization of insulin levels in adolescents with PCOS, several therapeutic options are available and in wide use, including oral contraceptives, metformin, thiazolidenediones and spironolactone. Overwhelmingly, the data on the safety and efficacy of these medications derive from the adult PCOS literature. Despite the paucity of randomized control trials to adequately evaluate these modalities in adolescents, their use, particularly that of metformin, has gained popularity in the pediatric endocrine community. In this article, we present an overview of the use of insulin sensitizing medications in PCOS and review both the adult and (where available) adolescent literature, focusing specifically on the use of metformin in both mono- and combination therapy
