BACKGROUND To determine the prevalence of asbestos-related changes on chest X-ray (CXR) and low-dose multidetector-row CT (MDCT) of the thorax in a cohort of formerly asbestos-exposed power industry workers and to assess the importance of common risk factors associated with specific radiological changes. METHODS To assess the influence of selected risk factors (age, time since first exposure,...
BACKGROUND The development of HIV drug resistance and subsequent virological failure are often cited as potential disadvantages of early cART initiation. However, their long-term probability is not known, and neither is the role of duration of infection at the time of initiation. METHODS Patients enrolled in the UK Register of HIV seroconverters were followed-up from cART initiation to last H...
Smoking is an established risk factor for pancreatic cancer; however, detailed examination of the association of smoking intensity, smoking duration, and cumulative smoking dose with pancreatic cancer is limited. The authors analyzed pooled data from the international Pancreatic Cancer Cohort Consortium nested case-control study (1,481 cases, 1,539 controls). Odds ratios and 95% confidence inte...
Although acyclovir prophylaxis against varicella zoster virus (VZV) infection for ≥1 year is recommended after allogeneic hematopoietic cell transplantation (HCT), the emergence of acyclovir-resistant viruses and adverse drug effects cannot be ignored. We investigated the cumulative incidence of VZV infection after allogeneic HCT in children receiving a shorter duration of acyclovir prophylaxis...
Narguileh is a water pipe. Narguileh smoking is a traditional pattern of smoking among Eastern Mediterranean women, publicly considered as a harmless entertainment. We performed a survey aimed at tracking chronic respiratory symptoms and alteration in respiratory functions in 77 female narguileh smokers, 77 cigarette smokers, and controls. A questionnaire about respiratory symptoms, quantity, a...
Introduction: Diabetic neuropathy is a common and sever complication of diabetes that its progression can lead to disability and even amputation in diabetic patients. The aim of this study was to determine the effective factors in the event of neuropathy and to assess the cumulative incidence of neuropathy in patients with type 2 diabetes. Methods:</st...
This series of two experiments investigated the auditory fatigue caused by pure tones up to 70 db sensation level and .1 to 10 seconds in duration, and charted the very quick recovery from these relatively mild stimuli. No cumulative fatigue effects were found up to 5 seconds of stimulation, and only a slight cumulative effect between 5 and 10 seconds at the louder levels. The fatigue occasione...
Childhood poverty is linked to a host of physical and psychological disorders during childhood and later in life. In the study reported here, we showed that the proportion of childhood spent in poverty from birth to age 9 was linked to elevated allostatic load, a marker of chronic physiological stress, in 17-year-olds. Furthermore, this prospective longitudinal relationship was mediated by cumu...
In this study, inelastic constitutive modelling is considered for the simulation of shear-thinning fluids through a circular channel. Numerical solutions are presented for power-law inelastic model, considering axisymmetric Poiseuille flow through a channel. The numerical simulation of such fluid is performed by using the Galerkin finite element approach based on artificial compression method (...
Measurements of elastic and inelastic cotunneling currents are presented on a two-terminal Aharonov-Bohm interferometer with a Coulomb-blockaded quantum dot embedded in each arm. Coherent current contributions, even in a magnetic field, are found in the nonlinear regime of inelastic cotunneling at a finite-bias voltage. The phase of the Aharonov-Bohm oscillations in the current exhibits phase j...
