INTRODUCTION AND HYPOTHESIS: Hysterectomy is often performed at the time of pelvic organ prolapse (POP) surgery; yet, there is insufficient evidence regarding the specific effect of hysterectomy on outcomes. We sought to determine the outcomes and associated short-term complications of mesh-based POP surgery with and without concurrent hysterectomy. METHODS: We utilized the New York Statewide Planning and Research Cooperation System (SPARCS) database to identify patients under 55 years of age undergoing surgeries for POP with mesh between 2009 and 2014...

: Epstein-Barr virus (EBV) infection is associated with B cell lymphomas in humans. The ability of EBV to convert human B cells into long-lived lymphoblastoid cell lines (LCLs) in vitro requires the collaborative effects of EBNA2 (which hijacks notch signaling), LMP1 (which mimics CD40 signaling), and EBNA 3A/3C (which inhibit oncogene-induced senescence and apoptosis). However, we recently showed that an LMP1-deleted EBV mutant induces B cell lymphomas in a newly developed cord blood-humanized mouse model that allows EBV-infected B cells to interact with CD4 T cells (the major source of CD40 ligand)...

The approval of bedaquiline to treat tuberculosis has validated adenosine triphosphate (ATP) synthase as an attractive target to kill Mycobacterium tuberculosis. Herein, we report the discovery of two diverse lead series imidazo[1,2-a]pyridine ethers (IPE) and squaramides (SQA) as inhibitors of mycobacterial ATP-synthesis. Through medicinal chemistry exploration, we established a robust structure activity relationship of these two scaffolds resulting in nanomolar potencies in an ATP-synthesis inhibition assay...

RbpA and CarD are essential transcription regulators in mycobacteria. Mechanistic analyses of promoter open complex (RPo) formation establish thatRbpA and CarD cooperatively stimulate formation of anintermediate (RP2) leading to RPo; formation of RP2 islikely a bottleneck step at the majority of mycobacterial promoters. Once RPo forms, CarD also disfavors its isomerization back to RP2.We determined a 2.76 Å-resolution crystal structure of a mycobacterial transcription initiation complex (TIC) with RbpA as well as a CarD/RbpA/TIC model...

BACKGROUND: Pediatric trauma patients are at high risk for development of venous thromboembolism (VTE). Our objective is to describe incidence, risk factors, and timing of development of VTE, anticoagulation complications, and long-term VTE outcomes in a critically injured pediatric population. PROCEDURE: We did a retrospective review of pediatric (0-17 years) trauma admissions to intensive care unit from 2005 to 2014. Our center employs VTE screening and prevention protocols for high-risk patients based on hypercoagulable history, age, injuries, and medical interventions...

BACKGROUND: Food allergy is an important public health problem because it affects children and adults, can be severe and even life-threatening, and may be increasing in prevalence. Beginning in 2008, the National Institute of Allergy and Infectious Diseases, working with other organizations and advocacy groups, led the development of the first clinical guidelines for the diagnosis and management of food allergy. A recent landmark clinical trial and other emerging data suggest that peanut allergy can be prevented through introduction of peanut-containing foods beginning in infancy...

Over the last four decades the HIV pandemic and advances in medical treatments that also cause immunosuppression have produced an ever-growing cohort of individuals susceptible to opportunistic pathogens. Of these, AIDS patients are particularly vulnerable to infection by the encapsulated yeast Cryptococcus neoformans Most commonly found in the environment in purine-rich bird guano, C. neoformans experiences a drastic change in nutrient availability during host infection, ultimately disseminating to colonize the purine-poor central nervous system...

Adult rat ultrasonic vocalizations (USVs) are a valuable tool for noninvasively assessing an animal's emotional state. USVs are produced in 1 of 2 frequency ranges labeled as 22 kHz or 50 kHz vocalizations. One USV subtype within the 50 kHz call category, constant frequency 50 kHz (CF 50 kHz) calls, is not viewed as signaling an emotional state. The current study tested the hypothesis that CF 50 kHz calls are related to a mild negative affective state. In Experiment 1, diazepam (1, 2.5, or 5 mg/kg), or control injections were administered prior to receiving a sequence of mild footshocks (0...

BACKGROUND: Preventing child maltreatment fatalities is a critical goal of the U.S. society and the military services. Fatality review boards further this goal through the analysis of circumstances of child deaths, making recommendations for improvements in practices and policies, and promoting increased cooperation among the many systems that serve families. The purpose of this article is to review types of child maltreatment death, proposed classification models, risk and protective factors, and prevention strategies...

Cheats are a pervasive threat to public goods production in natural and human communities, as they benefit from the commons without contributing to it. Although ecological antagonisms such as predation, parasitism, competition, and abiotic environmental stress play key roles in shaping population biology, it is unknown how such stresses generally affect the ability of cheats to undermine cooperation. We used theory and experiments to address this question in the pathogenic bacterium, Pseudomonas aeruginosa Although public goods producers were selected against in all populations, our competition experiments showed that antibiotics significantly increased the advantage of nonproducers...

Importance: Zoledronic acid, a third-generation aminobisphosphonate, reduces the incidence of skeletal-related events and pain in patients with bone metastases. The optimal dosing interval for zoledronic acid is uncertain. Objective: To determine whether zoledronic acid administered every 12 weeks is noninferior to zoledronic acid administered every 4 weeks. Design, Setting, Participants: Randomized, open-label clinical trial conducted at 269 academic and community sites in the United States...

BACKGROUND: Interorganizational collaboration management theory contends that cooperation between distinct but related organizations can yield innovation and competitive advantage to the participating organization. Yet, it is unclear if a multi-institutional collaborative can improve quality outcomes across communities. METHODS: We developed a large regional collaborative network of 15 hospitals and 24 emergency medical service agencies surrounding Dallas, Texas, and collected patient-level data on treatment times for acute myocardial infarctions...

PURPOSE: To estimate the prevalence, risk factors, prophylactic treatment and impact on mortality for venous thromboembolism (VTE) in patients with moderate to severe traumatic brain injury (TBI) treated in the intensive care unit. METHODS: A post hoc analysis of the erythropoietin in traumatic brain injury (EPO-TBI) trial that included twice-weekly lower limb ultrasound screening.

Indirect fitness benefits gained through kin-selected helping are widely invoked to explain the evolution of cooperative breeding behavior in birds. However, the impact of helpers on productivity of helped broods can be difficult to determine if the effects are confounded by territory quality or if the benefit of helpers is apparent only in the long term. In riflemen Acanthisitta chloris, helping and group membership are effectively decoupled as adult helpers are individuals that have dispersed from their natal territory and live independently from breeders in "kin neighborhoods...

What constitutes effective communication during conflict? Answering this question requires (a) clarifying whether communication expresses opposition versus cooperation and is direct versus indirect, (b) assessing the mechanisms through which communication effects relationships, and (c) identifying the contextual factors that determine the impact of communication. Recent research incorporating these components illustrates that direct opposition is beneficial when serious problems need to be addressed and partners are able to change, but can be harmful when partners are not confident or secure enough to be responsive...

We present a fully automated adaptive optics (AO) retinal image montaging algorithm using classic scale invariant feature transform with random sample consensus for outlier removal. Our approach is capable of using information from multiple AO modalities (confocal, split detection, and dark field) and can accurately detect discontinuities in the montage. The algorithm output is compared to manual montaging by evaluating the similarity of the overlapping regions after montaging, and calculating the detection rate of discontinuities in the montage...
