This paper proposes a discrete-time hazard regression approach based on the relation between hazard rate models and excess over threshold models, which are frequently encountered in extreme value modelling. The proposed duration model employs a exible link function and incorporates the grouped-duration analogue of the wellknown Cox proportional hazards model and the proportional odds model as s...

Soil samples from the three residential hubs of Chittagong city, Bangladesh were analyzed using gamma spectrometry to estimate radiation hazard due to natural radioactive sources and anthropogenic nuclide (137)Cs. The activity concentration of (226)Ra was found to be in the range 11-25 Bq.kg(-1), (232)Th in the range 38-59 Bq.kg(-1) and (40)K in the range 246-414 Bq.kg(-1). These results were u...

BACKGROUND Type 2 myocardial infarction and myocardial injury are common in clinical practice, but long-term consequences are uncertain. We aimed to define long-term outcomes and explore risk stratification in patients with type 2 myocardial infarction and myocardial injury. METHODS We identified consecutive patients (n=2122) with elevated cardiac troponin I concentrations (≥0.05 µg/L) at a t...

BACKGROUND Androgen excess is a defining feature of polycystic ovary syndrome (PCOS), which affects 10% of women and represents a lifelong metabolic disorder, with increased risk of type 2 diabetes, hypertension, and cardiovascular events. Previous studies have suggested an increased risk of nonalcoholic fatty liver disease (NAFLD) in individuals with PCOS and implicated androgen excess as a po...

OBJECTIVE To investigate the combined effects on adult mortality of overweight and smoking in late adolescence. DESIGN Record linkage study with Cox proportional hazard ratios adjusted for muscle strength, socioeconomic position, and age. SETTING Swedish military service conscription register, cause of death register, and census data. PARTICIPANTS 45 920 Swedish men (mean age 18.7, SD 0.5...

an important property of electromagnetic fields, which arises from the interaction between fields and chiral molecules, is called optical chirality. by enhancing this field property, while maintaining constant input power, we are able to increase absorption of circularly polarized light by chiral molecules of a certain handedness. this enhancement is achieved through the use of achiral plasmoni...

â â â â â â â  â â â  the excess liquidity of the open economy has become one main factor influencing the monetary markets, financial markets and even the whole macroeconomic. in era of the post-crisis, many countries have implemented the loose monetary policies, especially the quantitative easing policy in the u.s. which worsened the situation of the excess liquidity. under this background, it...

CONTEXT Although medical injuries are recognized as a major hazard in the health care system, little is known about their impact. OBJECTIVE To assess excess length of stay, charges, and deaths attributable to medical injuries during hospitalization. DESIGN, SETTING, AND PATIENTS The Agency for Healthcare Research and Quality (AHRQ) Patient Safety Indicators (PSIs) were used to identify medi...
