Comparison of head morphometric traits within five selected performance types of Quarter Horses (Equus caballus)

A study was conducted to investigate if morphometric facial measurements could be utilized to differentiate five categorical performance types of Quarter Horses. The five categories being Western, Halter, English, Reining, and Cutting. The measurements were collected from 323 registered Quarter Horses representing animals who ranged in age from one year to 30 years of age and one of three gender (Stallion, Gelding, and Mare) categories. Eight facial measurements were obtained from two geographic areas, Florida and Oregon. A correlation was performed and resulted in a reduction of the data from eight to five facial measurements, due to the presence of facial symmetry. The reduced data was subsequently analyzed by Multivariate Analysis, using the Wilks Lambda Analysis of Variance. The Main effects, age, gender, and categorical performance type were all significant (p0.05) and the three-way interaction age:gender:type was also not significant (p>0.05) Based upon the not significant (p>0.05) Based upon the results, the five original performance categories could be reduced to four (English, Halter, Cutting, and Western/Reining). This indicates that there are a number of similarities in facial measurements between the Western and Reining horses. Findings of this thesis indicate that selected facial morphometric traits exist and are characterized in the different performance categories

Does Cognitive Behavioral Therapy for Youth Anxiety Outperform Usual Care in Community Clinics? An Initial Effectiveness Test

Objective: Most tests of cognitive behavioral therapy (CBT) for youth anxiety disorders have shown beneficial effects, but these have been efficacy trials with recruited youths treated by researcher-employed therapists. One previous (nonrandomized) trial in community clinics found that CBT did not outperform usual care (UC). The present study used a more stringent effectiveness design to test CBT versus UC in youths referred to community clinics, with all treatment provided by therapists employed in the clinics. Method: A randomized controlled trial methodology was used. Therapists were randomized to training and supervision in the Coping Cat CBT program or UC. Forty-eight youths (56% girls, 8 to 15 years of age, 38% Caucasian, 33% Latino, 15% African-American) diagnosed with DSM-IV anxiety disorders were randomized to CBT or UC. Results: At the end of treatment more than half the youths no longer met criteria for their primary anxiety disorder, but the groups did not differ significantly on symptom (e.g., parent report, eta-square = 0.0001; child report, eta-square = 0.09; both differences favoring UC) or diagnostic (CBT, 66.7% without primary diagnosis; UC, 73.7%; odds ratio 0.71) outcomes. No differences were found with regard to outcomes of comorbid conditions, treatment duration, or costs. However, youths receiving CBT used fewer additional services than UC youths (χ21 = 8.82, p = .006). Conclusions: CBT did not produce better clinical outcomes than usual community clinic care. This initial test involved a relatively modest sample size; more research is needed to clarify whether there are conditions under which CBT can produce better clinical outcomes than usual clinical care.Psycholog

Prevalence of HIV in mental health service users: a retrospective cohort study.

Objective To examine the prevalence of HIV in a cohort of people who have used secondary mental health services in the UK. Design Retrospective cohort study. Setting Routinely collected clinical data from secondary mental health services in South London, UK available for research through the Clinical Record Interactive Search tool at the National Institute for Health and Care Research Maudsley Biomedical Research Centre were matched with pseudonymised national HIV surveillance data held by the UK Health Security Agency using a deterministic matching algorithm. Participants All adults aged 16+ who presented for the first time to mental health services in the South London and Maudsley (SLaM) National Health Service Trust between 1 January 2007 and 31 December 2018 were included. Primary outcome Point prevalence of HIV. Results There were 181 177 people who had contact with mental health services for the first time between 2007 and 2018 in SLaM. Overall, 2.47% (n=4481) of those had a recorded HIV diagnosis in national HIV surveillance data at any time (before, during or after contact with mental health services), 24.73 people per 1000. HIV point prevalence was highest in people with a diagnosed substance use disorder at 3.77% (n=784). A substantial percentage of the sample did not have a formal mental health diagnosis (27%), but even with those excluded, the point prevalence remained high at 2.31%. Around two-thirds of people had their diagnosis of HIV before contact with mental health services (67%; n=1495). Conclusions The prevalence of HIV in people who have had contact with mental health services was approximately 2.5 times higher than the general population in the same geographical area. Future work should investigate risk factors and disparities in HIV outcomes between those with and without mental health service contact

The Prospect of the Russian Language in Georgia. Insights from the Educated Youth

After the collapse of the Soviet Union, the status of the Russian language in the new-born Republics became a central issue. In the Southern Caucasus, all the Constitutions promulgated by the three Republics opted for ethnocentric language policies that accepted the titular language as the only State Language. However, the role of the Russian language as a lingua franca remained crucial for international communication and everyday interaction. It followed that it continued to play an important role also in education. The present study focuses on Georgia, where a strong derussification policy has taken place in the last decades and aims at understanding to what extent the use of Russian among the young generations has contracted. In particular, we present an analysis conducted on data collected via (i) a survey for young people consisting of questions on their sociolinguistic background and a proficiency test in Russian, and (ii) semi-structured interviews for teachers of Russian and English as Foreign Languages on the research topics

Integrin-Blocking Antibodies Delay Keratinocyte Re-Epithelialization in a Human Three-Dimensional Wound Healing Model

The α6β4 integrin plays a significant role in tumor growth, angiogenesis and metastasis through modulation of growth factor signaling, and is a potentially important therapeutic target. However, α6β4-mediated cell-matrix adhesion is critical in normal keratinocyte attachment, signaling and anchorage to the basement membrane through its interaction with laminin-5, raising potential risks for targeted therapy. Bioengineered Human Skin Equivalent (HSE), which have been shown to mimic their normal and wounded counterparts, have been used here to investigate the consequences of targeting β4 to establish toxic effects on normal tissue homeostasis and epithelial wound repair. We tested two antibodies directed to different β4 epitopes, one adhesion-blocking (ASC-8) and one non-adhesion blocking (ASC-3), and determined that these antibodies were appropriately localized to the basal surface of keratinocytes at the basement membrane interface where β4 is expressed. While normal tissue architecture was not altered, ASC-8 induced a sub-basal split at the basement membrane in non-wounded tissue. In addition, wound closure was significantly inhibited by ASC-8, but not by ASC-3, as the epithelial tongue only covered 40 percent of the wound area at 120 hours post-wounding. These results demonstrate β4 adhesion-blocking antibodies may have adverse effects on normal tissue, whereas antibodies directed to other epitopes may provide safer alternatives for therapy. Taken together, we conclude that these three-dimensional tissue models provide a biologically relevant platform to identify toxic effects induced by candidate therapeutics, which will allow generation of findings that are more predictive of in vivo responses early in the drug development process

Climate emergency summit III:nature-based solutions report

An RSGS & SNH report from the Climate Summit held in April 2020"The Climate Emergency is the result of burning fossils fuels and changes in the way we use the land that short-circuit global carbon and nitrogen cycles. To remain within safe climate limits (1.5-2°C), the remaining carbon budget for all people, and for all time, is now so small that stopping fossil fuel use, while essential, will not by itself address the problem. Changing the way we use the land and sea is now essential. Nature-based solutions are vital to creating a safe operating space for humanity.

COVID-19 vaccines reduce the risk of serious COVID-19 outcomes; however, their effectiveness in people with obesity is incompletely understood. We studied the relationship among body mass index (BMI), hospitalization and mortality due to COVID-19 among 3.6 million people in Scotland using the Early Pandemic Evaluation and Enhanced Surveillance of COVID-19 (EAVE II) surveillance platform. We found that vaccinated individuals with severe obesity (BMI > 40 kg/m2) were 76% more likely to experience hospitalization or death from COVID-19 (adjusted rate ratio of 1.76 (95% confidence interval (CI), 1.60–1.94). We also conducted a prospective longitudinal study of a cohort of 28 individuals with severe obesity compared to 41 control individuals with normal BMI (BMI 18.5–24.9 kg/m2). We found that 55% of individuals with severe obesity had unquantifiable titers of neutralizing antibody against authentic severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) virus compared to 12% of individuals with normal BMI (P = 0.0003) 6 months after their second vaccine dose. Furthermore, we observed that, for individuals with severe obesity, at any given anti-spike and anti-receptor-binding domain (RBD) antibody level, neutralizing capacity was lower than that of individuals with a normal BMI. Neutralizing capacity was restored by a third dose of vaccine but again declined more rapidly in people with severe obesity. We demonstrate that waning of COVID-19 vaccine-induced humoral immunity is accelerated in individuals with severe obesity. As obesity is associated with increased hospitalization and mortality from breakthrough infections, our findings have implications for vaccine prioritization policies.Publisher PDFPeer reviewe
