Renal cell cancer (RCC) is the major type of kidney cancer with increasing incidence. Obesity is one of the well-established risk factors for RCC. Meta-analyses including multiple cohort and case-control studies have found a consistent positive association between obesity and RCC. The association appeared to be independent of other RCC risk factors including hypertension and has been often stronger in women, although a positive association has also been observed in men. Obesity has been largely measured as body mass index (BMI)...

Human immunodeficiency virus (HIV) epidemic has undoubtedly increased the incidence of tuberculosis (TB) globally, posing a formidable global health challenge affecting 1.2 million cases. Pulmonary TB assumes utmost significance in the programmatic perspective as it is readily transmissible as well as easily diagnosable. HIV complicates every aspect of pulmonary tuberculosis from diagnosis to treatment, demanding a different approach to effectively tackle both the diseases. In order to control these converging epidemics, it is important to diagnose early, initiate appropriate therapy for both infections, prevent transmission and administer preventive therapy...

BACKGROUND: We believe that it is important that governments understand the reliability of the mortality data which they have at their disposable to guide policy debates. In many instances, verbal autopsy (VA) will be the only source of mortality data for populations, yet little is known about how the accuracy of VA diagnoses is affected by the reliability of the symptom responses. We previously described the effect of the duration of time between death and VA administration on VA validity...

During the past two decades, several studies showed reduced rates of hepatocellular carcinoma recurrence in patients with HCV-related cirrhosis after interferon-based antiviral therapies respect to untreated controls, even without reaching viral clearance. The recent development of new all-oral regimens with direct-acting antivirals has radically improved the therapeutic management of hepatitis C. Nevertheless, paradoxical, or at least unexpected, high rates of both occurrence and recurrence of hepatocellular carcinoma after a treatment with direct-acting antivirals, have been reported in the recent literature...

Multiple sclerosis (MS) patients treated with natalizumab often face the uncommon but severe complication of developing progressive multifocal leukoencephalopathy (PML). PML may be further complicated by immune reconstitution inflammatory syndrome (IRIS) after the removal of the drug. Since both PML and IRIS are associated with high morbidity and mortality rates, early clinical and radiological diagnosis of these complications is of paramount importance. Here, we report a case of an adult male patient who was diagnosed with PML after receiving natalizumab therapy for 6 years for the treatment of MS...

Introduction: The aim of this study was to define and characterise differences in the level of obstetric care provided to immigrant and German women. Materials and Methods: An analysis of the Virchow Hospital's birth registers was conducted for the years 1974, 1984 and 1994. The study population of 5445 patients was grouped according to ancestry/family origin on the basis of a name analysis, and subsequently also according to parity (primiparous or multiparous). On name analysis 2741 women were defined as German, 1598 were grouped as women of Turkish origin and 810 as immigrants of other origin...

Interrelations between cytokines, produced by invasive ductal carcinoma (IDC) and fibroadenoma (FA) of the breast, and angiogenic growth factor VEGF-A, expressed in IDC and FA, were investigated. The analysis of the cytokine profiles of IDC and FA was performed by cultivation of tumor biopsy specimens in vitro. Testing of the cytokine-producing reserve of the tumors for production of VEGF-A was conducted by culturing samples of IDC and FA in a medium containing polyclonal activator (a complex of phytohemagglutinin, concanavalin A, and lipopolysaccharide)...

REVIEW

Respiratory syncytial virus (RSV) infection is a significant cause of hospitalization of children in North America and one of the leading causes of death of infants less than 1 year of age worldwide, second only to malaria. Despite its global impact on human health, there are relatively few therapeutic options available to prevent or treat RSV infection. Paradoxically, there is a very large volume of information that is constantly being refined on RSV replication, the mechanisms of RSV-induced pathology, and community transmission...

Thyroid hormones (TH) regulate metabolism, but are typically suppressed during times of stressful physiological conditions, including fasting. Interestingly, prolonged fasting in northern elephant seal pups is associated with reliance on a lipid-based metabolism and increased levels of circulating thyroid hormones that are partially attributed to active secretion as opposed to reduced clearance. This apparent paradox is coupled with complementary increases in cellular TH-mediated activity suggesting that in mammals naturally adapted to prolonged fasting TH are necessary to support metabolism...

Purpose Evidence on overweight, obesity, and an increased risk of cancer continues to accumulate and was updated in the 2016 handbook on weight control from the International Agency for Research on Cancer (IARC). The underlying primary data, together with dose-response meta-analysis and, finally, pooled analysis of individual participant data, add insight into the relation between obesity and cancer risk and prognosis. We summarize the evidence for mortality from prostate cancer, hematologic malignancies, and kidney cancer...

High-latitude lakes are particularly sensitive to the effects of global climate change, demonstrating earlier ice breakup, longer ice-free seasons, and increased water temperatures. Such physical changes have implications for diverse life-history traits in taxa across entire lake food webs. Here, we use a five-decade time series from an Alaskan lake to explore effects of climate change on growth and reproduction of a widely distributed lacustrine fish, the three-spine stickleback (Gasterosteus aculeatus). We used multivariate autoregressive state-space (MARSS) models to describe trends in the mean length for multiple size classes and to explore the influence of physical (date of ice breakup, surface water temperature) and biological (density of con- and heterospecifics) factors...

Lineage commitment and differentiation of mesenchymal stromal cells (MSCs) into osteoblasts in vitro is enhanced by a potent synthetic form of glucocorticoid (GC), dexamethasone (Dex). Paradoxically, when used chronically in patients, GCs exert negative effects on bone, a phenomenon known as glucocorticoid-induced osteoporosis in clinical practice. The mechanism on how GC differentially affects bone precursor cells to become mature osteoblasts during osteogenesis remains elusive. In this study, the dose and temporal regulation of Dex on MSC differentiation into osteoblasts were investigated...

Stent implantation using a Cheatham Platinum (CP) stent for coarctation of the aorta (CoA) is a promising treatment alternative to traditional surgical repair. However, there are no earlier reports in the literature focusing on use of this stent in a Taiwanese patient. Herein we report a 16-year-old boy with CoA presenting with heart murmur and exercise intolerance who underwent successful CP stent placement. However, severe hypertension with arterial blood pressure increasing to 207/104 mmHg occurred four hours after stent implantation...

Wolfgang Stroebe
In this article, I address the paradox that university grade point averages have increased for decades, whereas the time students invest in their studies has decreased. I argue that one major contributor to this paradox is grading leniency, encouraged by the practice of university administrators to base important personnel decisions on student evaluations of teaching. Grading leniency creates strong incentives for instructors to teach in ways that would result in good student evaluations. Because many instructors believe that the average student prefers courses that are entertaining, require little work, and result in high grades, they feel under pressure to conform to those expectations...

The vast majority of public health students exhibit the kind of 'clean living' that is routinely advocated as highly desirable by health promoters. However, this social and cultural distance from many of the most important health issues faced in our society creates a barrier for understanding and working with other population groups. Insider status, knowledge and understanding is essential in developing true insight in developing culturally appropriate interventions. Referencing Rose's influential prevention paradox, a revision is suggested stating that prevention measures are often developed by individuals outside the population in question and may offer little actual benefit to that population...

BACKGROUND: -Ventricular arrhythmia is a leading cause of cardiac mortality. Most antiarrhythmics present paradoxical pro-arrhythmic side effects, culminating in a greater risk of sudden death. METHODS: -We describe a new regulatory mechanism linking mitogen-activated kinase kinase-7 (MKK7) deficiency with increased arrhythmia vulnerability in hypertrophied and failing hearts using mouse models harbouring MKK7 knockout or overexpression. The human relevance of this arrhythmogenic mechanism is evaluated in human induced pluripotent stem cells-derived cardiomyocytes (iPSC-CMs)...

The prevalence of myopia in developed countries in East and Southeast Asia has increased to more than 80% in children completing schooling, whereas that of high myopia has increased to 10%-20%. This poses significant challenges for correction of refractive errors and the management of pathological high myopia. Prevention is therefore an important priority. Myopia is etiologically heterogeneous, with a low level of myopia of clearly genetic origins that appears without exposure to risk factors. The big increases have occurred in school myopia, driven by increasing educational pressures in combination with limited amounts of time spent outdoors...
