Transvaginal ultrasound-guided oocyte retrieval in cattle: State-of-the-art and its impact on the in vitro fertilization embryo production outcome.

Transvaginal ultrasound-guided oocyte retrieval (commonly called OPU) and in vitro embryo production (IVP) in cattle has shown significant progress in recent years, in part, as a result of a better understanding of the full potential of these tools by end users. The combination of OPU and IVP (OPU-IVP) has been successfully and widely commercially used worldwide. The main advantages are a greater number of embryos and pregnancies per unit of time, faster genetic progress due to donor quick turn around and more elite sires mating combinations, larger spectrum of female age (calves, prepuberal, heifer, cow) and condition (open, pregnant) from which to retrieve oocytes, a reduced number of sperm (even sexed) required to fertilize the oocytes, among other benefits.

Culturally enhancing a group-based motivational interviewing substance use prevention program for Latine youth.

Background: Group Motivational Interviewing for Teens (GMIT) has been effective in reducing youth substance use in diverse communities, yet more research is needed to determine its efficacy in reducing tobacco and alternative tobacco products (ATP) use among Latine adolescents. This study modified GMIT to include a focus on ATPs (GMIT-ATP). GMIT was also linguistically translated so it could be offered in English and Spanish, culturally enhanced, and parent sessions were added (GMIT-ATP + P).

Effect of multiple agricultural stressors on freshwater ecosystems: The role of community structure, trophic status, and biodiversity-functioning relationships on ecosystem responses.

The toxicity and widespread use of agricultural pesticides threaten freshwater biodiversity, but their long-term effects under different nutrient concentrations are poorly understood. We evaluated the single or combined effects of two pesticides (chlorpyrifos and diuron) under different nutrient regimes (mesotrophic and eutrophic) on community structure and ecosystem functions in replicated pond mesocosms. The individual application of nutrients and pesticides affected community composition and species richness.

Do fluoroquinolone agents produce therapeutic benefits or harmful effects in patients with periodontitis? A systematic review and meta-analysis.

The adjunctive use of fluoroquinolone (FQ) agents in patients with periodontitis produces contradictory results. There has been no meta-analysis performed based on the evaluations of FQ use that would enable making appropriate clinical decisions. Our study aimed to evaluate, via a systematic review and metaanalysis conducted in accordance with the PRISMA (Preferred Reporting Items for Systematic reviews and Meta-Analyses) guidelines, the clinical benefits, antimicrobial effects and safety profiles of the FQ agents administered to periodontitis patients under a conventional treatment regime.

Multiple stressors in Mediterranean coastal wetland ecosystems: Influence of salinity and an insecticide on zooplankton communities under different temperature conditions.

Temperature increase, salinity intrusion and pesticide pollution have been suggested to be among the main stressors affecting the biodiversity of coastal wetland ecosystems. Here we assessed the single and combined effects of these stressors on zooplankton communities collected from a Mediterranean coastal lagoon. An indoor microcosm experiment was designed with temperature variation (20 °C and 30 °C), salinity (no addition, 2.

Integrating Tobacco Prevention Skills into an Evidence-Based Intervention for Adolescents with ADHD: Results from a Pilot Efficacy Randomized Controlled Trial.

Adolescents with attention-deficit/hyperactivity disorder (ADHD) are at high risk for tobacco use, but tobacco use prevention strategies are not regularly incorporated into evidence-based ADHD interventions. We conducted a pilot randomized-controlled trial to determine the feasibility of integrating tobacco use prevention skills into a behavioral treatment for ADHD and to provide preliminary efficacy data comparing a combined (ADHD + tobacco) intervention (N = 40) to an ADHD only intervention (N = 23) on tobacco risk outcomes. Sixty-three adolescents (72% male; 13-17 years) with ADHD and their caregivers were randomly assigned to condition and families were masked to condition.

Effect of pterostilbene on development, equatorial lipid accumulation and reactive oxygen species production of in vitro-produced bovine embryos.

The pterostilbene (PT) molecule is a phytoalexin with a reducing effect on reactive oxygen species (ROS) and with a capacity to block lipogenesis. However, the potential reducing effects of PT on equatorial lipid accumulation and ROS have not yet been elucidated for in vitro-derived bovine embryos. The present study evaluated the effects of concentrations of 3, 1, 0.

Engaging with the Richmond Community to Reduce Pediatric Asthma Disparities: Findings from a Community-engaged Needs Assessment.

Childhood asthma disparities persist, with children living in low-income areas experiencing worse morbidity. We partnered with a community-academic research team and stakeholders to conduct a needs assessment to understand barriers and supports to asthma treatment. We convened a community advisory board, comprised of parents of children with asthma, youth with asthma, and members of key community organizations.

Ventilation and laboratory confirmed acute respiratory infection (ARI) rates in college residence halls in College Park, Maryland.

Strategies to protect building occupants from the risk of acute respiratory infection (ARI) need to consider ventilation for its ability to dilute and remove indoor bioaerosols. Prior studies have described an association of increased self-reported colds and influenza-like symptoms with low ventilation but have not combined rigorous characterization of ventilation with assessment of laboratory confirmed infections. We report a study designed to fill this gap.

The relation between body image perceptions, parental messages, and depressive symptoms among Latinx college students.

Objectives: This study examines the role of parental messages about body image in relation to body image dissatisfaction (BID) and depressive symptoms among Latinx college students. We assessed negative and positive messages about body image from mothers and fathers to examine the indirect effect of BID in explaining links from parental communication to depressive symptoms.

Method: The sample included 198 Latinx college students in the southeastern United States (age range 18-25, 70% female).

Usefulness of a Novel System for Feedback of Patient-Reported Outcome Measures in Children Recovering From Burns.

The Burn Outcomes Questionnaire for children ages 5-18 years (BOQ5-18) is a widely used, reliable, and valid parent-reported outcome measure designed to assess children's recovery from burn injuries in 12 physical and psychosocial domains. This study evaluated the feasibility, acceptability, and usefulness of a feedback system that delivered BOQ and Pediatric Symptom Checklist (PSC-17; a widely used measure of psychosocial functioning) results to burn care clinicians prior to an outpatient appointment or a postoperative surgical encounter. The BOQ and the PSC-17 were administered to the parents of 147 children receiving outpatient or surgical care in two pediatric burn hospitals.

The Use of a Brief Measure to Assess Longitudinal Changes in Appearance Concerns for Youth Recovering From Burn Injuries.

Burns are among the most common injuries to children, and, although survival rates have improved, many burn survivors are left with scars and/or other visible differences, which may be associated with anxiety, depression, and/or low self-esteem. A better understanding of the prevalence and persistence of these problems in child and adolescent burn survivors might lead to an expanded paradigm of care and possibly to better outcomes. The present study provides longitudinal prevalence data for the Appearance Concerns (AC) subscale of the parent-reported Burn Outcomes Questionnaire (BOQ) for 5- to 18-year-old children and identifies patient characteristics associated with higher risk for appearance concerns.

Temperature Effects Explain Continental Scale Distribution of Cyanobacterial Toxins.

Insight into how environmental change determines the production and distribution of cyanobacterial toxins is necessary for risk assessment. Management guidelines currently focus on hepatotoxins (microcystins). Increasing attention is given to other classes, such as neurotoxins (e.

Readability of Spanish language online information for the initial treatment of burns.

Objective: This study's aim is to identify the most popular online resources for burn treatment information available in the Spanish language, and to evaluate the readability of this information.

Methods: The phrase "tratamiento de quemaduras" (burn treatment) was entered into search engines Google and Bing on 9/15/2014 and 9/13/2017. The top 12 Spanish web results on each site were identified and analyzed using Readability Studio Professional Edition v2012.

Phase-contrast cerebrospinal fluid flow magnetic resonance imaging in qualitative evaluation of patency of CSF flow pathways prior to infusion of chemotherapeutic and other agents into the fourth ventricle.

Purpose: Nuclear medicine studies have previously been utilized to assess for blockage of cerebrospinal fluid (CSF) flow prior to intraventricular chemotherapy infusions. To assess CSF flow without nuclear medicine studies, we obtained cine phase-contrast MRI sequences that assess CSF flow from the fourth ventricle down to the sacrum.

Methods: In three clinical trials, 18 patients with recurrent malignant posterior fossa tumors underwent implantation of a ventricular access device (VAD) into the fourth ventricle, either with or without simultaneous tumor resection.
