Maternal nutrient restriction during pregnancy alters fetal programming, which modifies the growth and health of the offspring in postnatal life. In cattle, nutrient restriction during pregnancy can be a result of environmental or economic factors, but little is known about how it alters the physiology of the fetus and affects future reproductive or growth efficiency. This study used female monozygotic twins, produced through in vitro fertilization and embryo splitting, to determine the effect of moderate maternal nutrient restriction on fetal development. Recipient Angus cross heifers pregnant with one twin were fed a diet meeting 100% National Research Council (NRC) total energy requirements (n = 4; control), whereas recipient heifers pregnant with the second twin were fed at 70% of NRC total energy requirements (n = 4; restricted) from gestational day (GD) 158 to GD 265 in Calan gate feeders. Recipient heifers were killed at GD 265. Change in maternal metabolic body weight was greater from zero in restricted heifers than controls (P 0.10). Histological analyses of the fetal pancreas revealed no differences in endocrine cell number or localization. mTOR target Results indicate that a modest late gestation nutritional restriction impairs development of the fetal pancreas in the cow. Additional research will be needed to determine if these developmental changes lead to altered glucose and insulin homeostasis in the adult.

To explore outcomes of women with planned cesarean hysterectomies, with or without use of internal iliac intravascular occlusive balloon catheter or uterine artery embolization (UAE).

We retrospectively reviewed adult women who underwent a planned cesarean hysterectomy, 2004-2019. All planned cases were included, regardless of indication. Planned surgeries were divided into three groups balloon placement, UAE, or no intervention. Patients with balloon placement were further subdivided into balloons placed but not deployed or balloons placed and deployed intraoperatively. Hemorrhage was defined as estimated blood loss (EBL) ≥1,500 mL. An adverse outcome was defined as one or more of the following intensive care unit admission, thromboembolism, ureteral stent placement, amputation, or reoperation. Basic descriptive and inferential statistics were used to explore differences among groups and adverse outcomes.

A total of 34 patients underwent planned cesarean hysterectomy. Ten patients (29.4%) had balloons oyed vs. 20.0% no intervention; P ≤ 0.01).

Balloon placement, regardless of deployment, may not be beneficial to women undergoing a planned cesarean hysterectomy. Although UAE was also associated with adverse outcomes, it may be a better option for reducing intraoperative blood loss among patients with a planned cesarean hysterectomy.

Social network interventions that take advantage of existing individual and group relationships may help overcome the significant patient, provider, and system level barriers that contribute to low hepatitis C Virus (HCV) treatment uptake among people who inject drugs (PWID).

We conducted semi-structured interviews with 20 HCV antibody positive PWID (15 male, 5 female) in Baltimore, Maryland, USA. We utilized thematic analysis and employed both inductive and deductive coding techniques to assess perceptions of barriers and facilitators of social network interventions for HCV testing, linkage to care, and treatment among PWID.

PWID perceived a high prevalence of HCV within their social networks, especially within injection drug use networks. Overwhelmingly, participants reported a willingness to discuss HCV and provide informational, instrumental, and emotional support to their network members. Support included sharing knowledge, such as where and how to access HCV care, as well as sharing lived experien provide support to network members who face significant stigma related to both HCV and drug use.

Social network based interventions have potential to increase HCV treatment uptake among PWID. To be successful, these interventions will need to train peers to share accurate information and personal experiences with HCV testing and treatment and enhance their ability to provide support to network members who face significant stigma related to both HCV and drug use.A numerical model is presented for the acoustic vaporization threshold of a dodecafluoropentane (or perfluoropentane) microdroplet. The model is based on the Rayleigh-Plesset equation and is improved by properly treating the supercritical state that occurs when a bubble collapses rapidly and by employing the van der Waals equation of state to consider the supercritical state. The present computations demonstrate that the microdroplet vaporization behavior depends intricately on bubble compressibility, liquid inertia and phase-change heat transfer under acoustic excitation conditions. We present acoustic pressure-frequency diagrams for bubble growth regimes and the ADV threshold conditions. The effects of acoustic parameters, fluid properties and the droplet radius on the ADV threshold are investigated.

We evaluated the safety of REPLICA, a CAD/CAM-designed patient-specific titanium mandible, in patients with mandibular defects not suitable for reconstruction with traditional techniques.

We performed a cohort study with a composite primary outcome assigned at the end of a 1-year follow-up. The outcome was assigned in the presence of all the following 1) absence of intraoral or skin extrusion of REPLICA; 2) decrease or cessation of oral pain; 3) stability or increase in mouth opening; 4) resumption of oral feeding without the need of nasogastric tube; 5) absence of fracture at multidetector computer tomography (MDCT); 6) absence of displacement (MDCT); 7) absence of screw loosening (MDCT). The secondary outcome was the patient-reported QOL at 6months of follow-up as detected by the EORTC QLQ-C30 and QLQ-H&N35 questionnaires.

Between March 2012 and June 2017, 18 consecutive patients, with a median (IQR) age of 67 (65;74) underwent reconstruction of mandibular defects with REPLICA at our Unit. The primary outcome was reached by 14 of the 18 patients.
