RESUMO

BACKGROUND: Acute lower respiratory infection (ALRI) is the leading cause of child mortality, especially in the developing world. Polymorphisms in the interleukin 4 (IL-4) gene have been linked to a variety of human diseases. OBJECTIVES: To investigate whether the IL-4 -590C/T (rs2243250) polymorphism could be a genetic marker for susceptibility to ALRIs in young Egyptian children. METHODS: This was a multicenter study conducted on 480 children diagnosed with pneumonia or bronchiolitis, and 480 well-matched healthy control children. Using PCR-RFLP analysis, we genotyped a -590C/T (rs2243250) single nucleotide polymorphism of the IL-4 gene promoter, meanwhile the serum IL-4concentration was measured by ELISA. RESULTS: The frequency of the IL-4 -590 T/T genotype and T allele were overrepresented in patients with ALRIs in comparison to the control group (OR = 2.0; [95% confidence interval [CI]: 1.38-2.96]; for the T/T genotype) and (OR: 1.3; [95%CI: 1.07-1.56]; for the T allele; P < 0.01). The IL-4 -590 T/T genotype was associated with significantly higher mean serum IL-4 concentration (58.7 ± 13.4 pg/mL) compared to the C/T genotype (47.6 ± 11 pg/mL) and the C/C genotype (34.8 ± 9.6 pg/mL); P < 0.01. CONCLUSION: The IL-4 -590C/T (rs2243250) polymorphism may contribute to susceptibility to ALRIs in young Egyptian children.

RESUMO

PURPOSE: To measure surgical site infection (SSI) rates among gastrointestinal surgeries and to identify the associated risk factors. PATIENTS AND METHODS: We conducted a multicenter, retrospective, surveillance-based study of adults undergoing gastric, colon, and small bowel (SB) procedures from January to December 2016. Univariate and multivariate analyses were conducted to determine the predictive variables in each surgery. RESULTS: In total, 71 of 2,099 patients developed SSI - 0.8%, 19.8%, and 10.8% following gastric, colon, and SB surgeries, respectively. In gastric surgery, the risk factors identified by univariate analysis were age, duration, wound class, risk index, emergency, and scope use (P<0.05). Logistic regression analysis revealed that the laparoscopic approach was the only significant predictor, with an inverse relationship of SSI rate vs open gastric surgery (P<0.05). Prolonged duration was a significant risk factor for developing SSI in colon surgery, and emergency was a significant risk for development of SSI in SB surgery. Gram-negative bacilli were the main causative pathogens, with a high percentage of multidrug-resistant organisms. CONCLUSION: Variances in SSI rates and risk factors among gastric, colon, and SB surgery were detected. The use of an endoscope in gastric surgeries exhibited a protective effect against the development of SSI. The reduction of the SSI rate can be achieved by targeted preventive interventions for the identified risk factors.

RESUMO

BACKGROUND AND OBJECTIVES: Over the past few decades, cesarean section (CS) rates are steadily increasing in most of the middle- and high-income countries. However, most of the pregnant women (particularly undergoing CS) are not screened for hepatitis C virus (HCV); hence, neonates born to HCV-positive mother could be a source of future HCV infection. In this study, the role of the CS and other surgical interventions in HCV transmission in Egypt, the highest endemic country of HCV-4, was investigated. METHODS: From January to June 2016, a prospective cohort study was conducted among 3,836 pregnant women in both urban and rural areas across Egypt for HCV screening in both mothers and neonates born to HCV-positive mother. All pregnant women were screened during third trimester or just before delivery, neonates born to HCV-positive mothers were evaluated within 24-h postdelivery to record vertical transmission cases. Data mining (DM)-driven computational analysis was used to quantify the findings. RESULTS: Among 3,836 randomized pregnant women, HCV genotype 4 was identified in 80 women (2.08%). Out of 80 HCV-infected women, 18 have experienced surgical intervention (22.5%) and 62 CS (77.5%). HCV vertical transmission was identified in 10 neonates, 10/80 (12.5%). CONCLUSION: Screening women who had experienced surgical intervention or CS during child bearing period and before pregnancy might prevent HCV mother-to-child transmission (MTCT). CS should be ethically justified to decrease global HCV transmission.
