BACKGROUND The aim of this meta-analysis was to compare the outcomes of proximal femoral nail (PFN) and dynamic hip screw (DHS) in treatment of intertrochanteric fractures. MATERIAL AND METHODS Relevant randomized or quasi-randomized controlled studies comparing the effects of PFN and DHS were searched for following the requirements of the Cochrane Library Handbook. Six eligible studies invol...

BACKGROUND This study aims to examine the possible impacts of resettlement on birth rates by using the length of stay variable in the 2000 Demographic and Health Survey (DHS). METHODS Data in all three rounds of Gambella Administrative Region's Demographic and Health Surveys (DHS) are analyzed. The neighboring administrative region of Benishangul-Gumuz is used as a control. The multivariate a...

The differentiation of naive CD4(+) T lymphocytes into Th1 and Th2 lineages generates either cellular or humoral immune responses. Th2 cells express the cytokines IL-4, -5, and -13, which are implicated in asthma and atopy. Much has been published about the regulation of murine Th2 cytokine expression, but studies in human primary T cells are less common. We have developed a method for differen...

BACKGROUND Integration of medical care across clinicians and settings could enhance the quality of care for patients. To date, there is limited data on the levels of integration in practice. Our objective was to compare primary care clinicians' perceptions of clinical integration and three sub-aspects in two healthcare systems: Kaiser Permanente, Northern California (KPNC) and the Danish health...

Abstract Introduction In neck of femur (NOF) patients presenting with co-existent history malignancy, it is regarded as good practice to obtain pre-operative full-length X-Rays (FLF-XRs) identify metastatic disease distal the fracture site and aid operative planning. Whether availability FLF-XRs in trauma meeting influences surgeon's choice fixation method between intramedullary nail (IMN) or d...

Intertrochanteric fractures (ITFs) are the most common type of fractures requiring surgical intervention. They also have the highest surgical mortality among orthopedic operations. Among the many different techniques used for fixation of this type of fracture, use of the Dynamic Hip Screw (DHS) has gained wide acceptance. This current study was designed to assess positive predictive value of ti...

Sphingolipid long-chain bases and their phosphorylated derivatives, for example, sphingosine-1-phosphate in mammals, have been implicated as signaling molecules. The possibility that Saccharomyces cerevisiae cells also use long-chain-base phosphates to regulate cellular processes has only recently begun to be examined. Here we present a simple and sensitive procedure for analyzing and quantifyi...

INTRODUCTION In spite of a high prevalence of HIV infection among adolescents and young adults in sub-Saharan Africa, uptake of HIV testing and counseling among youth in the region remains sub-optimal. The objective of this study was to assess factors that influence uptake of HIV testing and counseling among youth aged 15-24 years in sub-Saharan Africa. METHODS This study used the Demographic...

We report the demonstration of CdTe/MgxCd1-xTe double heterostructures (DHs) with a carrier lifetime of 3.6 μs and an interface recommendation velocity of 1.2 cm/s, comparable to or even better than the best values reported for GaAs/Al0.5Ga0.5As (18 cm/s) and GaAs/Ga0.5In0.5P (1.5 cm/s) DHs. Combined with a p-contact layer (8 nm a-SiCy:H + 4 nm a-Si:H), devices consisting of MgxCd1-xTe/CdTe/Mg0...
