BACKGROUND: Surgical site infection is the main cause of morbidity and mortality in post-cesarean section patients. The objective of this study was to determine the preoperative factors associated with the surgical site infection in patients undergoing cesarean emergency section in the Goyeneche Hospital of Arequipa.METHODS: We conducted a cases-control study on women who presented with surgical site infection after cesarean section in a hospital in Arequipa, Peru. We evaluated associated factors to surgical site infection after cesarean section (sociodemographics and clinical variables). For the inferential analysis, we estimated logistic regression using odds ratio.RESULTS: Out of a total of 4346 cesarean sections, only 2.4% developed surgical site infection. The associated factors to surgicalsite infection were mild anemia (OR: 2.80), moderate anemia (OR:2.71), number of vaginal examinations higher than five (OR:2.71) and onset of labor (OR: 1.95).CONCLUSION: Patients with risk factors such as anemia, onset of labor and five or more vaginal examinations should be evaluated after surgery to prevent surgical site infection.

COVID-19 vaccines have achieved a significant reduction in mortality, yet objective estimates are needed in specific settings. We aimed to determine the effectiveness of COVID-19 vaccination at a referral hospital in Lambayeque, Peru. We conducted a retrospective cohort study from February to September 2021. We included hospitalized patients with COVID-19, whose data were stored in NotiWeb, a patient data system of the Peruvian Ministry of Health. We applied a propensity score-weighting method according to baseline characteristics of patients, and estimated hazard ratios (HR) using Cox regression models. Of 1553 participants, the average age was 55 years (SD: 16.8), 907 (58%) were male, and 592 (38%) deceased at 28-day follow-up. Before hospital admission, 74 (4.8%) had been immunized with at least one vaccine dose. Effectiveness against death in vaccinated patients was 50% at 90-day follow-up (weighted HR 0.50, 95% CI 0.28–0.89). Our results support the effectiveness of COVID-19 vaccination against death and provide information after early immunization in Peru.

Background We aimed to evaluate the correlation of neck circumference with abdominal circumference and body mass index in patients with metabolic syndrome in Chocope, Trujillo. Methods This cross-sectional study included patients with untreated metabolic syndrome. Health professionals measured the anthropometric parameters of participants as per the international guidelines. Pearson’s correlation coefficients and single and multiple regression models were used for analysis. Results Data from 250 participants showed homogeneous distribution with respect to age, comorbidities, and biochemical properties according to sex. The mean age was 53.6 years. A positive correlation of neck circumference with abdominal circumference (r = 0.6 and 0.74 for females and males, respectively) and body mass index (r = 0.51 and 0.65 for females and males, respectively) was observed. The linear correlation model showed that a 1-cm increase in neck circumference increased the abdominal circumference by 2.20 cm (p < 0.001) and 2.27 cm (p < 0.001) and body mass index by 0.72 kg/m2 (p < 0.001) and 0.94 kg/m2 (p < 0.001) in males and females, respectively, independent of other variables. Conclusions In participants with metabolic syndrome in this study, neck circumference showed a strong correlation with abdominal circumference and body mass index. This anthropometric parameter can be extremely useful for evaluating obesity among patients with metabolic syndrome.
