The Department of Homeland Security's (DHS) Science and Technology (S&T) Directorate plays a role in public health that extends beyond biodefense. These responsibilities were exercised as part of the 2014-16 Ebola outbreak, leading to productive and beneficial contributions to the international public health response and improved operations in the United States. However, we and others have iden...

Objective To evaluate long-term radiographic and functional outcomes between dynamic hip screw (DHS) and proximal femoral nail antirotation (PFNA) fixation for treatment of osteoporotic type 31-A1 intertrochanteric femoral fractures (IFFs) among elderly patients Methods A retrospective comparative study was carried out. Follow-up was performed at 1, 3, 6, 9, and 12 months postoperatively and ye...

Generation of clonal zebrafish will facilitate large-scale genetic screening and help us to overcome other biological and biotechnological challenges due to their isogenecity. However, protocols for the development of clonal lines have not been optimized. Here, we sought to develop a novel method for generation of clonal zebrafish by androgenesis induced by cold shock. Androgenetic zebrafish do...

Natural methods of contraception were widely used in developed countries until the late 1960s to space and limit childbirth. In France, when the first contraceptive surveys were conducted, researchers noticed that the use of natural methods was underreported, and questions to correct for this bias were subsequently added. The Demographic and Health Surveys do not currently include questions spe...

This study attempted to compare the muscle fiber morphological responses to dynamic electrical muscle stimulation (DEMS) and dynamic hydraulic stimulation (DHS) in rats under hindlimb suspension (HLS). DEMS at 1 Hz, 50 Hz and 100 Hz for 10 min/day, 5 days/week were introduced to the animals' right quadriceps. Static and 2 Hz DHS were introduced to the right tibiae of other animal groups on a "1...

Postoperative blood recovery in eighty elderly patients (11 male, 69 female) treated for femoral neck fracture was prospectively studied. Twenty-eight patients underwent hemiarthroplasty for intracapusular fracture and 52 underwent Dynamic Hip Screw fixation for extracapsular femoral neck fracture. The mean blood drainage in the postoperative period and the mean drop in haemoglobin level was hi...

Fixation with a dynamic hip screw (DHS) is one of the most common methods for stabilizing intertrochanteric fractures, except for unstable and reverse oblique fracture types. However, failure is often observed in osteoporotic patients whereby the lag screw effectively 'cuts out' through the weak bone. Novel anti-migration blades have been developed to be used in combination with a lag screw ('B...

Although a high proportion of marriages in Asia are consanguineous (i.e. contracted between close biological relatives), with some notable exceptions, there is a death of demographic and anthropological literature on the association between consanguinity and fertility. This paper presents an overview of the prevalence of consanguineous marriages in selected South and Southeast Asian countries, ...

Between September 1984 and June 1985, a total of 75 adolescent girls, 35 vegetarians residing in a Seventh-Day Adventist school and 40 nonvegetarians residing in a private non-Adventist boarding school, under went measurement of their plasma hormone levels in the follicular and luteal phases of their menstrual cycles as well as dietary intake measured by 3-day food records, medical history, hei...

BACKGROUND Communication errors during handoffs are a leading cause of sentinel events. The Accreditation Council for Graduate Medical Education 2011 duty hour standards (DHS) increase the frequency of handoffs. OBJECTIVE The goal of this study was to determine if a multidisciplinary group handoff bundle improves communication while working within the 2011 DHS. METHODS During 1-month pilot ...
