TL;DR: Depression was significantly associated with the perception of severity and suffering induced by the skin diseases and should be a consideration by dermatologists in the effective management of skin diseases.
Abstract: Background Early diagnosis and treatment of depression are of vital importance in dermatological patients. Objective Our purpose was to evaluate the prevalence of depression among patients visiting a dermatology clinic in southern Israel. Methods Patients who visited the dermatology clinic were interviewed using the Mini International Neuropsychiatric Interview screening tool. Results The study included 384 patients. The screening questionnaire identified 37 patients (9.6%) with major depression, 3 patients (0.8%) with minor depression, and 74 patients (19.3%) with depressive symptoms. Higher prevalence of depression was found among widowers, among divorced or separated patients, and in unemployed patients. Depression was significantly associated with the perception of severity and suffering induced by the skin diseases. Limitations The study was conducted in a cross-sectional design. To confirm causality, a longitudinal study should be conducted. Conclusion Depression should be a consideration by dermatologists in the effective management of skin diseases.

TL;DR: In this article, the incidence of pemphigus in the Jewish population was threefold higher than that in Arabs (9.6 vs 3.2 cases per million per year, respectively; P P P ǫ = 0.068).
Abstract: Background The epidemiology of pemphigus in different ethnic populations exposed to similar environments is unknown. Trends in the incidence of pemphigus based on an immunopathologically validated cohort have not been investigated. Objectives We sought to estimate the incidence of pemphigus in Israel and to investigate differences between the 2 major ethnic populations. Methods Pemphigus incidence was retrospectively estimated from January 2000 to December 2015 in 2 Israeli regions with a total population of 1.56 million inhabitants. Results One hundred eighty patients with pemphigus (mean age, 54.70 ± 16 years) were identified. The overall estimated incidence was 7.2 per million inhabitants per year (95% confidence interval, 6.2-8.3). The incidence in the Jewish population was threefold higher than that in Arabs (9.6 vs 3.2 cases per million per year, respectively; P P P = .068). Limitations This study was limited by the retrospective design and the small population. Conclusions The incidence of pemphigus in Israel is among the highest reported worldwide and is significantly more frequent among Jews.

TL;DR: Patients with SLE had a greater prevalence of CD than matched controls in a large case-control study, and a complex combination of genetic, immunological and novel environmental factors may explain this positive association.

TL;DR: In this paper, the effect of smoking on H. pylori eradication rates after controlling for sociodemographic confounders was assessed. And the authors found that smoking significantly increased the likelihood of unsuccessful first-line treatment for H.pylori infection.

TL;DR: The 11th edition of Harrison's Principles of Internal Medicine welcomes Anthony Fauci to its editorial staff, in addition to more than 85 new contributors.
Abstract: The 11th edition of Harrison's Principles of Internal Medicine welcomes Anthony Fauci to its editorial staff, in addition to more than 85 new contributors. While the organization of the book is similar to previous editions, major emphasis has been placed on disorders that affect multiple organ systems. Important advances in genetics, immunology, and oncology are emphasized. Many chapters of the book have been rewritten and describe major advances in internal medicine. Subjects that received only a paragraph or two of attention in previous editions are now covered in entire chapters. Among the chapters that have been extensively revised are the chapters on infections in the compromised host, on skin rashes in infections, on many of the viral infections, including cytomegalovirus and Epstein-Barr virus, on sexually transmitted diseases, on diabetes mellitus, on disorders of bone and mineral metabolism, and on lymphadenopathy and splenomegaly. The major revisions in these chapters and many

TL;DR: The theory proposed here provides a taxonomy for numerical linear algebra algorithms that provide a top level mathematical view of previously unrelated algorithms and developers of new algorithms and perturbation theories will benefit from the theory.
Abstract: In this paper we develop new Newton and conjugate gradient algorithms on the Grassmann and Stiefel manifolds. These manifolds represent the constraints that arise in such areas as the symmetric eigenvalue problem, nonlinear eigenvalue problems, electronic structures computations, and signal processing. In addition to the new algorithms, we show how the geometrical framework gives penetrating new insights allowing us to create, understand, and compare algorithms. The theory proposed here provides a taxonomy for numerical linear algebra algorithms that provide a top level mathematical view of previously unrelated algorithms. It is our hope that developers of new algorithms and perturbation theories will benefit from the theory, methods, and examples in this paper.

TL;DR: The greatest need is for agents that enhance insulin sensitivity, halt the progressive pancreatic β-cell failure that is characteristic of T2DM and prevent or reverse the microvascular complications.
Abstract: Type 2 diabetes mellitus (T2DM) is an expanding global health problem, closely linked to the epidemic of obesity. Individuals with T2DM are at high risk for both microvascular complications (including retinopathy, nephropathy and neuropathy) and macrovascular complications (such as cardiovascular comorbidities), owing to hyperglycaemia and individual components of the insulin resistance (metabolic) syndrome. Environmental factors (for example, obesity, an unhealthy diet and physical inactivity) and genetic factors contribute to the multiple pathophysiological disturbances that are responsible for impaired glucose homeostasis in T2DM. Insulin resistance and impaired insulin secretion remain the core defects in T2DM, but at least six other pathophysiological abnormalities contribute to the dysregulation of glucose metabolism. The multiple pathogenetic disturbances present in T2DM dictate that multiple antidiabetic agents, used in combination, will be required to maintain normoglycaemia. The treatment must not only be effective and safe but also improve the quality of life. Several novel medications are in development, but the greatest need is for agents that enhance insulin sensitivity, halt the progressive pancreatic β-cell failure that is characteristic of T2DM and prevent or reverse the microvascular complications.
