Introduction Genetic causes of the intellectual disability Nonsyndromic Autosomal-Recessive Intellectual Disability Syndrome (MRT47, MIM 616193) are mutations in the recently described FMN2 (formin 2 gene). Case report A boy with intellectual disability had a novel homozygous nonsense mutation (c.2245C > T/p.Gln749*) leading to a premature stop codon in exon 6 of the FMN2 (NM_001305424) gene detected by Clinical Exome Sequencing (CES). Conclusion Clinical features of a patient with a novel nonsense FMN2 mutation is presented. We urge the change in the OMIM nomenclature from Mental Retardation, Autosomal Recessive 47 (MRT47, MIM 616193) to 'Nonsyndromic Autosomal-Recessive Intellectual Disability Syndrome'.Objective Sleep is a natural activity of humans that affects physical and mental health; therefore, sleep disturbance may lead to fatigue and lower productivity. This study examined 1 million samples included in the Taiwan National Health Insurance Research Database (NHIRD) in order to predict sleep disorder in an asthma cohort from 2002-2010.Methods The disease histories of the asthma patients were transferred to sequences and matrices for the prediction of sleep disorder by applying machine learning (ML) algorithms, including K-Nearest Neighbors (KNN), Support Vector Machine (SVM), and Random Forest (RF), and deep learning (DL) models, including Recurrent Neural Network (RNN), Long Short-Term Memory (LSTM), Gated Recurrent Units (GRU), and Convolution Neural Network (CNN).Results Among 14,818 new asthma subjects in 2002, there were 4469 sleep disorder subjects from 2002 to 2010. Selleckchem Alectinib The KNN, SVM, and RF algorithms were demonstrated to be successful sleep disorder prediction models, with accuracies of 0.798, 0.793, and 0.813, respectively (AUC 0.737, 0.690, and 0.719, respectively). The results of the DL models showed the accuracies of the RNN, LSTM, GRU, and CNN to be 0.744, 0.815, 0.782, and 0.951, respectively (AUC 0.658, 0.750, 0.732, and 0.934, respectively).Conclusions The results showed that the CNN model had the best performance for sleep disorder prediction in the asthma cohort.The proportional hazards (PH) model is commonly used in epidemiology despite the stringent assumption of proportionality of hazards over time. We previously showed, using detailed simulation data, that the impact of a modest risk factor cannot be estimated reliably using the PH model in the presence of confounding by a strong, time-dependent risk factor. Here, we examine the same and related issues using a real dataset. Among 97,303 women in the prospective Nurses' Health Study cohort from 1994 through 2010, we used PH regression to investigate how effect estimates for cigarette smoking are affected by increasingly detailed specification of time-dependent exposure characteristics. We also examined how effect estimates for fine particulate matter (PM2.5), a modest risk factor, are affected by finer control for time-dependent confounding by smoking. The objective of this analysis is not to present a credible estimate of the impact of PM2.5 on lung cancer risk, but to show that estimates based on the PH model arponents of smoking history. The association with PM2.5 is residually confounded by smoking and modified by smoking status. These findings underscore limitations of the PH model and emphasize the advantages of directly estimating hazard functions to characterize time-varying exposure and risk. The hazard function, not the relative hazard, is the fundamental measure of risk in a population. As a consequence, the use of time-dependent PH models does not address crucial issues introduced by temporal factors in epidemiological data.Objectives To evaluate the influence of low socioeconomic status (SES) on mortality among patients with granulomatosis with polyangiitis (GPA).Methods Using nationwide registers, we established a cohort of 827 patients diagnosed with GPA in the public hospital system of Denmark. For each patient, information regarding educational level, civil status, employment status, and comorbidities at time of GPA diagnosis was collected. We used Cox regression analyses to calculate hazard ratios (HRs) adjusted for age, gender, calendar period of GPA diagnosis, and Charlson Comorbidity Index score for preceding illnesses as a measure of relative risk of death. We assessed the risk of death associated with three measures of low SES basic schooling only, civil status as single, and being unemployed or recipient of disability pension.Results The median age of patients at GPA diagnosis was 61 (interquartile range 51-69) years, and 508 were 18-64 years old. During a total of 4337 person-years, 237 patients died. Among patients aged 18-64 years at GPA diagnosis, all three measures of low SES were identified as risk factors for death [basic schooling only HR = 2.04, 95% confidence interval (CI) 1.30-3.19; civil status as single HR = 1.95, 95% CI 1.24-3.05; being unemployed or recipient of disability pension HR = 2.96, 95% CI 1.72-5.08]. The association between low SES and mortality was less pronounced among patients aged ≥ 65 years.Conclusions Our observations indicate that low SES is associated with increased mortality in GPA, especially among patients of working age.Introduction Long-term, even indefinite treatment with nucleos(t)ide analogs (NAs) is the current first-line therapy for patients with chronic hepatitis B (CHB), regardless of its histological stage. Guidelines and recommendations on duration and endpoints of NA therapy in CHB are not identical and change over time.Areas covered The authors review NA discontinuation approaches and views with an emphasis on HBeAg-negative patients based on published studies relevant to the topic, stressing on whether or not the optimal endpoint of HBsAg loss is practically achievable.Expert opinion Discontinuation of NA therapy in HBeAg-negative noncirrhotic patients has to be considered after long-term effective treatment with controlled liver disease activity, undetectable viremia, and significant decline in serum HBsAg titers. Close post-treatment monitoring is required for early intervention in cases of severe clinical relapse. Immediate retreatment hampers the favorable outcome of HBsAg clearance (functional cure) and should be avoided in transient ALT flares.
