Prevalence of psychological and mental health symptoms among nursing professionals during the COVID-19 pandemic in the Americas: Systematic review and meta-analysis.

To assess the prevalence of mental health symptoms in nursing professionals during the COVID-19 pandemic on the American continent. A systematic review and meta-analysis of observational studies that estimated the prevalence of mental health symptoms in nursing professionals during the COVID-19 pandemic was performed through bibliographic database searches. A three-level meta-analysis model was used with the inverse variance method, tau was estimated via restricted maximum likelihood and logistic transformation, and heterogeneity was presented as tau and I.

We applied a questionnaire before and one month after an intervention about the comprehensive care of substance users, containing: sociodemographic information, knowledge, the Treatment Spirituality/Religiosity Scale, and the Drug and Drug Problems Perceptions Questionnaire.

Partial ablation of endometrial glands in dogs after exposure to progestin during the neonatal period.

Bitches with uteri devoid of endometrial glands should be sterile, and consequently could contribute to the population control of dogs. Considering that an inadequate exposure of the female reproductive system to steroids can lead to the formation of the uterine gland knock-out (UGKO) phenotype in some species, the aim of this study was to evaluate the effect of serial applications of medroxyprogesterone acetate (MPA) from birth until the age of six months on the development of endometrial glands in bitches. For this purpose, 16 female mongrel dogs from different litters were distributed into either an MPA group (n = 8), animals treated with 10 mg kg sc (Promone-E, Pfizer, Brasil) at 3-week intervals, from day one after birth until the age of six months, or a control group (n = 8), composed of animals that only received a 0.

The prevalence and phenotype in Brazilian patients with inflammatory bowel disease.

Background: The epidemiology of inflammatory bowel disease (IBD) varies in different countries. This study aimed to assess phenotype, medications, prevalence and incidence of IBD in the State of Espírito Santo, Brazil.

Methods: Patients with IBD who utilized the Public Medication-Dispensing System of the Department of Health of Espírito Santo, between August 2012 and July 2014.

Imaging paracoccidioidomycosis: A pictorial review from head to toe.

Paracoccidioidomycosis is an infectious disease characterized primarily by pulmonary involvement and potential dissemination to other organs, mainly mucosa and skin; however, it can affect any organ in the body. Although difficult to diagnose purely based on imaging, imaging is important for diagnosis, follow-up, and assessment of disease-related complications. We provide a comprehensive review of the most notable imaging findings of paracoccidioidomycosis.

Effect of deslorelin acetate treatment in oocyte recovery and in vitro embryo production in domestic cats.

Objectives The present study investigated the effect of contraceptive treatment with deslorelin acetate on in vitro embryo production and oocyte recovery in domestic queens. Methods Twenty-one mature domestic cats were used. Eleven queens (treated group) and one tom were kept in an experimental cattery, and 10 queens were privately owned (control group).

Objective: To identify the distribution and frequency of computed tomography (CT) findings in patients with nosocomial rapidly growing mycobacterial (RGM) infection after laparoscopic surgery.

Method: A descriptive retrospective study in patients with RGM infection after laparoscopic surgery who underwent CT imaging prior to initiation of therapy. The images were analyzed by two radiologists in consensus, who evaluated the skin/subcutaneous tissues, the abdominal wall, and intraperitoneal region separately.

Maternal anemia induces changes in immunological and nutritional components of breast milk.

Objective: The effects of low maternal hemoglobin levels on the immunological and nutritional components of breast milk at different maturation stages were investigated.

Methods: Colostrum, transitional and mature milk were collected from 25 mothers with normal hemoglobin levels (control group) and 18 mothers with hemoglobin levels below 11 g/dL (anemia group). Total protein, antibodies, complement proteins, fat and calorie, lipase, iron, transferrin levels, total iron-binding capacity, latent iron-binding capacity (LIBC) and transferrin saturation index (TSI) were determined.

Lactate in bitches with pyometra.

Lactate is a compound produced by the anaerobic metabolism of glucose, and hyperlactataemia occurs when the rate of production of lactate exceeds the rate of elimination. This occurs in situations of hypoxia and tissue hypoperfusion. Lactate has been considered a useful prognostic indicator in critically ill patients.

Progesterone (PR), oestrogen (ER-α and ER-β) and oxytocin (OTR) gene expression in the oviduct and uterus of pregnant and non-pregnant bitches.

The aim was to assess hormone receptor gene expression in the oviduct and uterus during canine pregnancy. Nineteen pregnant bitches divided into four groups were ovariohysterectomized (OVH) at either day 8, 12, 21 or 60 of pregnancy, and five non-pregnant females underwent OVH 12 days after the pre-ovulatory Luteinizant Hormone (LH) surge and served as controls. RT-qPCR for progesterone (PR), oestrogen (ER-α and ER-β) and oxytocin (OTR) receptors was performed on the oviduct and uterine tissue.

Ovarian activity reversibility after the use of deslorelin acetate as a short-term contraceptive in domestic queens.

The objective was to evaluate ovarian activity reversibility in domestic queens after short-term contraceptive treatment with deslorelin acetate. Ten mature queens were used. In all queens, the estrous cycle was evaluated every 72 h by vaginal cytology (VC) and behavior assessments.

Mullerian duct anomalies: MR imaging.

Mullerian duct anomalies (MDAs) are rare, affecting approximately 1% of all women and about 3% of women with poor reproductive outcomes. These congenital anomalies usually result from one of the following categories of abnormalities of the mullerian ducts: failure of formation (no development or underdevelopment) or failure of fusion of the mullerian ducts. The American Fertility Society (AFS) classification of uterine anomalies is widely accepted and includes seven distinct categories.

Compactified strings as quantum statistical partition function on the Jacobian torus.

We show that the solitonic contribution of toroidally compactified strings corresponds to the quantum statistical partition function of a free particle living on higher dimensional spaces. In the simplest case of compactification on a circle, the Hamiltonian is the Laplacian on the 2g-dimensional Jacobian torus associated with the genus g Riemann surface corresponding to the string world sheet. T duality leads to a symmetry of the partition function mixing time and temperature.

Platelet activation markers in patients with peripheral arterial disease--a prospective comparison of different platelet function tests.

Peripheral vascular disease (PVD) is an indicator of diffuse atherosclerosis and is associated with a greatly increased incidence of coronary heart and cerebrovascular disease. Although several studies have assessed whether in vivo platelet activation takes place in patients with PVD, no data are available comparing different platelet function tests in this patient population. We have compared prospectively four tests for the measurement of in vivo platelet activation (plasma betaTG, plasma PF4, intraplatelet betaTG and urinary excretion of 11-dehydro-TXB2) and one in vitro platelet function test (ADP-induced platelet aggregation) in 63 well-characterized patients with intermittent claudication and in 18 age- and sex-matched healthy volunteers.

Diabetes mellitus, hypercholesterolemia, and hypertension but not vascular disease per se are associated with persistent platelet activation in vivo. Evidence derived from the study of peripheral arterial disease.

Background: Previous studies relating increased thromboxane (TX) biosynthesis to cardiovascular risk factors do not answer the question whether platelet activation is merely a consequence of more prevalent atherosclerotic lesions or reflects the influence of metabolic and hemodynamic disturbances on platelet biochemistry and function.

Methods And Results: We examined 64 patients with large-vessel peripheral arterial disease and 64 age- and sex-matched control subjects. TXA2 biosynthesis was investigated in relation to cardiovascular risk factors by repeated measurements of the urinary excretion of its major enzymatic metabolite, 11-dehydro-TXB2, by radioimmunoassay.
