This study aimed to investigate the deletion polymorphisms of the genes of the glutathione S-transferase family GSTT1 and GSTM1 in patients with Polycystic Ovarian Syndrome (PCOS), comparing them with a control population.
 
  Blood was collected from 219 women (110 with PCOS and 109 controls) and genomic DNA was extracted. For the analysis of polymorphisms, the technique used was multiplex PCR.  https://www.selleckchem.com/products/c-178.html  In the statistical analysis, the chi-square test and multiple logistic regression were used.
 
  There is no association between the GSTM1 null and GSTT1 null genotypes with PCOS when analyzed separately (P = 0.616 and P = 0.188). The analysis of the combined genotypes showed differences between the groups (P < 0.05), evidencing that the genotypic combination GSTT1 positive and GSTM1 negative is more frequent among patients. In the multivariate analysis, smoking was more frequent in the control group (OR = 0.22; 95% CI - 0.87-0.57; P = 0.002) while the presence of a family history of PCOS (OR = 2, 96; 95% CI - 1.54-5.68; P = 0.001) was more frequent in women with PCOS.
 
  In the studied sample, the deletion polymorphisms of the GSTT1 and GSTM1 genes isolated are not associated with PCOS, but in combination, they may be implicated in the etiology of the condition.

  Good knowledge of the coronavirus disease 2019 (COVID-19) among healthcare workers is essential for keeping health systems active and controlling the outbreak. We aimed to investigate the knowledge and attitudes of Emergency Medical Service (EMS) employees who fight COVID-19 at the forefront.
 
  A total of 400 EMS workers (doctors, nurses, emergency medical technicians, paramedics, and ambulance drivers) were included in this study. Knowledge, attitude, and preventive behaviors for COVID-19 were evaluated using an online questionnaire.
 
  A total of 275 EMS workers participated in the study with a response rate of 68.8%. The respondents reported that their highest common sources of knowledge about COVID-19 were social media and television (n=240, 88%). Overall, > 96% of the participants had adequate knowledge about the transmission routes of COVID-19. Among the respondents, 36% of them were unaware of the correct hand washing or scrubbing technique. In addition, 78% of the participants had poor knowledge about floor and surface disinfection. The majority of the participants exhibited inaccurate attitudes toward the use of personal preventive equipment. More than half of EMS workers (52%) agreed that a surgical mask is not enough during the procedures that do not generate aerosol. Moreover, a significant proportion of the participants (66%) perceived that a N95 mask is required.
 
  As a consequence, although emergency workers have sufficient basic knowledge about COVID-19, there is a need for postgraduate training in many subjects.

  In the future, surgery will be centralized in hospitals with the best value (excellent results with reduced cost). High-performance teams will be required; however, available data concerning the specific abilities necessary to build and manage them are poor.
 
  Share the set of competencies and skills established to build and lead a high-performance general surgery team.
 
  In November 2012, a general surgery team started its activities at a tertiary hospital in Sao Paulo, Brasil. The model consisted of high volume performed by a small team. Experienced surgeons, motivated, and with technical and moral excellence were selected. A sense of unity was created and goals were shared. Complex cases were discussed daily and a prospective database to follow outcomes was established. The payment value was above the market.
 
  In 6 years and 4 months, 11,006 surgical procedures were performed (8,597 electives and 2,409 in an urgent setting). Cholecystectomy was the most common procedure (4,101; being 3,676 electives), followed by inguinal hernioplasty (n 1,827) and appendectomy (n 925). A total of 449 elective oncologic procedures were performed. The surgical site infection rate in clean procedures was 0.12%, 80 patients required re-do surgery (2.4% in an urgent setting and 0.2% of the electives). There were 22 postoperative deaths (0.66% for urgent and 0.07% for electives), 5 of the 6 deaths in elective patients were in oncologic cases.
 
  A competent surgical team, inserted in a model that favors performance and values the individual can deliver high volume with exceptional results.

  To assess knowledge about diabetic foot, care measures, and the importance attached to serial treatment in a group of high-risk diabetic foot patients.
 
  This is a cross-sectional study, carried out in a tertiary hospital, with 25 patients undergoing serial treatment for diabetic foot. The tabulation of the data occurred through the use of three methodological figures core idea, key expressions, and the collective subject discourse.
 
  It became evident that even among high-risk patients with diabetic foot, there is no complete knowledge about the definition of the disease. Despite this, all participants reported practicing daily care measures, including frequent inspection of the feet, food care, and attention to footwear. Regarding the importance of serial treatment, there was unanimous recognition of the relevance of this practice, which improves self-care discipline, optimizes the understanding of the disease, and helps to prevent progression.
 
  Authentic speeches in the context of a pathology of considerable prevalence manifested, in an unprecedented way, with conceptions about its definition, care measures, and importance of serial treatment in a high-risk group.
