Does Hypothyroidism Affect Gastrointestinal Motility?

Background. Gastrointestinal motility and serum thyroid hormone levels are closely related. Our aim was to analyze whether there is a disorder in esophagogastric motor functions as a result of hypothyroidism. Materials and Methods. The study group included 30 females (mean age ± SE 45.17 ± 2.07 years) with primary hypothyroidism and 10 healthy females (mean age ± SE 39.40 ± 3.95 years). All cases underwent esophagogastric endoscopy and scintigraphy. For esophageal scintigraphy, dynamic imaging of esophagus motility protocol, and for gastric emptying scintigraphy, anterior static gastric images were acquired. Results. The mean esophageal transit time (52.56 ± 4.07 sec for patients; 24.30 ± 5.88 sec for controls; P = .02) and gastric emptying time (49.06 ± 4.29 min for the hypothyroid group; 30.4 ± 4.74 min for the control group; P = .01) were markedly increased in cases of hypothyroidism. Conclusion. Hypothyroidism prominently reduces esophageal and gastric motor activity and can cause gastrointestinal dysfunction

Development and validation of a case definition for problematic menopause in primary care electronic medical records

Abstract Background Menopause is a normal transition in a woman’s life. For some women, it is a stage without significant difficulties; for others, menopause symptoms can severely affect their quality of life. This study developed and validated a case definition for problematic menopause using Canadian primary care electronic medical records, which is an essential step in examining the condition and improving quality of care. Methods We used data from the Canadian Primary Care Sentinel Surveillance Network including billing and diagnostic codes, diagnostic free-text, problem list entries, medications, and referrals. These data formed the basis of an expert-reviewed reference standard data set and contained the features that were used to train a machine learning model based on classification and regression trees. An ad hoc feature importance measure coupled with recursive feature elimination and clustering were applied to reduce our initial 86,000 element feature set to a few tens of the most relevant features in the data, while class balancing was accomplished with random under- and over-sampling. The final case definition was generated from the tree-based machine learning model output combined with a feature importance algorithm. Two independent samples were used: one for training / testing the machine learning algorithm and the other for case definition validation. Results We randomly selected 2,776 women aged 45–60 for this analysis and created a case definition, consisting of two occurrences within 24 months of International Classification of Diseases, Ninth Revision, Clinical Modification code 627 (or any sub-codes) OR one occurrence of Anatomical Therapeutic Chemical classification code G03CA (or any sub-codes) within the patient chart, that was highly effective at detecting problematic menopause cases. This definition produced a sensitivity of 81.5% (95% CI: 76.3-85.9%), specificity of 93.5% (91.9-94.8%), positive predictive value of 73.8% (68.3-78.6%), and negative predictive value of 95.7% (94.4-96.8%). Conclusion Our case definition for problematic menopause demonstrated high validity metrics and so is expected to be useful for epidemiological study and surveillance. This case definition will enable future studies exploring the management of menopause in primary care settings

Triglyceride-glucose index levels in patients with congenital hypogonadotropic hypogonadism and the relationship with endothelial dysfunction and insulin resistance

Introduction: The risk of cardiometabolic diseases is increased in patients with hypogonadism. The triglyceride-glucose (TyG) index is a novel surrogate marker of insulin resistance and is associated with cardiovascular diseases. We investigated the TyG index levels and the relationship with endothelial dysfunction and insulin resistance in patients with congenital hypogonadotropic hypogonadism (CHH). Material and methods: A total of 98 patients with CHH (mean age 21.66 ± 1.99 years) and 98 healthy control subjects (mean age 21.69 ± 1.21 years) were enrolled. The demographic parameters, TyG index, asymmetric dimethylarginine (ADMA), high-sensitivity C-reactive protein (hs-CRP), and homeostatic model assessment of insulin resistance (HOMA-IR) levels were measured for all participants. Results: The patients had higher waist circumference (p < 0.001), triglycerides (p = 0.001), insulin (p = 0.003), HOMA-IR (p = 0.002), ADMA (p < 0.001), and TyG index (p < 0.001) levels and lower HDL-C (p = 0.044) and total testosterone (p < 0.001) levels compared to healthy control subjects. TyG index levels significantly correlated with the ADMA (r = 0.31, p = 0.003) and HOMA-IR (r = 0.32, p < 0.001) levels. TyG index was also determinant of HOMA-IR levels (ß = 0.20, p = 0.018). Conclusion: The results of the present study show that patients with CHH had increased TyG index levels. Also, the TyG index is independently associated with insulin resistance in patients with CHH. Long-term follow-up studies are warranted to find out the role of the TyG index in determining cardiometabolic risk in patients with hypogonadism.

Care after premenopausal risk-reducing salpingo-oophorectomy in high-risk women: Scoping review and international consensus recommendations

Women at high inherited risk of ovarian cancer are offered risk-reducing salpingo-oophorectomy (RRSO) from age 35 to 45 years. Although potentially life-saving, RRSO may induce symptoms that negatively affect quality of life and impair long-term health. Clinical care following RRSO is often suboptimal. This scoping review describes how RRSO affects short- and long-term health and provides evidence-based international consensus recommendations for care from preoperative counselling to long-term disease prevention. This includes the efficacy and safety of hormonal and non-hormonal treatments for vasomotor symptoms, sleep disturbance and sexual dysfunction and effective approaches to prevent bone and cardiovascular disease

Use of Oral Bisphosphonates by Older Adults with Fractures and Impaired Renal Function

ABSTRACTBackground: The manufacturers of oral bisphosphonates (alendronate, risedronate) recommend avoiding use of these drugs in patients with renal impairment. However, many patients who have osteoporosis or who are at risk of fracture are elderly and may have renal impairment. This situation poses a quandary for clinicians in deciding how best to manage osteoporosis in this high-risk population.Objective: To synthesize published evidence regarding the use and safety of oral bisphosphonates for patients with impaired renal function.Methods: The following databases were searched up to October 2010: PubMed, MEDLINE, Embase, the Cochrane Library, and International Pharmaceutical Abstracts. The following key words and terms were used for the searches: bisphosphonates, alendronate, risedronate, Fosamax, Actonel, "renal failure", "renal insufficiency", "chronic kidney disease", and "end-stage renal disease". The manufacturers of Fosamax and Actonel were asked to provide information about use of their products in patients with renal impairment, including unpublished pharmaco - kinetic studies or reports of adverse drug events.Results: The search yielded 2 post hoc analyses of safety data, 1 case-control study, 1 case series, 4 retrospective chart analyses, and 2 prospective studies. According to these publications, numerous patients with decreased renal function have received bisphosphonates and have experienced improvement in bone mineral density and/or reduction in risk of fractures, with no increase in adverse effects. Increased renal damage occurred in some individuals with underlying renal disorders, as described in case reports.Conclusions: Although the literature is limited, there is evidence that alendronate and risedronate are well tolerated and effective when used by individuals with renal impairment. Further research is required to confirm the benefits and risks of using these medications in patients with renal impairment.RÉSUMÉContexte : Les fabricants de bisphosphonates oraux (alendronate, risédronate) recommandent d'éviter l'emploi de ces médicaments chez les patients souffrant d'insuffisance rénale. Cependant, de nombreux patients souffrant d'ostéoporose ou qui sont à risque de fracture sont des personnes âgées qui pourraient souffrir d'insuffisance rénale. Cette situation est un véritable dilemme pour les cliniciens qui doivent décider de la meilleure conduite à tenir pour traiter l'ostéoporose chez cette population à risque élevé.Objectif : Mettre en lumière les données probantes publiées sur l'emploi et l'innocuité des bisphosphonates oraux chez les patients souffrant d'insuffisance rénale.Méthodes : Les bases de données suivantes ont été examinées : PubMed, MEDLINE, Embase, Bibliothèque Cochrane et International Pharmaceutical Abstracts. Les mots clés et termes suivants ont été utilisés pour les recherches : bisphosphonates, alendronate, risédronate, Actonel, Fosamax, « insuffisance rénale », « maladie rénale chronique » et « insuffisance rénale terminale ». Les recherches dans les bases de données ont été faites jusqu'en octobre 2010. On a demandé aux fabricants d'Actonel et de Fosamax de fournir de l'information sur l'utilisation de leurs produits chez les patients atteints d'insuffisance rénale, y compris les résultats d'études pharmacocinétiques inédites ou les rapports d'événements indésirables liés aux médicaments.Résultats : La recherche a révélé deux analyses a posteriori de données sur l'innocuité, une étude cas-témoin, une série de cas, quatre analyses rétrospectives de dossiers médicaux et deux études prospectives. D'après ces documents, de nombreux patients atteints d'insuffisance rénale ont reçu des bisphosphonates et présenté un accroissement de leur densité minérale osseuse ou une réduction du risque de fractures, sans augmentation des effets indésirables. On a observé une augmentation des lésions rénales chez certains patients présentant des troubles rénaux sous-jacents, comme décrit dans plusieurs observations cliniques.Conclusions : Bien que la documentation soit limitée, des données probantes montrent que l'alendronate et le risédronate sont bien tolérés et efficaces dans les cas d'insuffisance rénale. Des recherches plus approfondies sont nécessaires pour confirmer les bienfaits et les risques de ces médicaments chez les personnes souffrant d'insuffisance rénale
