SummaryBackgroundSurgical site infection (SSI) is one of the most common infections associated with health care, but its importance as a global health priority is not fully understood. We quantified the burden of SSI after gastrointestinal surgery in countries in all parts of the world.MethodsThis international, prospective, multicentre cohort study included consecutive patients undergoing elective or emergency gastrointestinal resection within 2-week time periods at any health-care facility in any country. Countries with participating centres were stratified into high-income, middle-income, and low-income groups according to the UN's Human Development Index (HDI). Data variables from the GlobalSurg 1 study and other studies that have been found to affect the likelihood of SSI were entered into risk adjustment models. The primary outcome measure was the 30-day SSI incidence (defined by US Centers for Disease Control and Prevention criteria for superficial and deep incisional SSI). Relationships with explanatory variables were examined using Bayesian multilevel logistic regression models. This trial is registered with ClinicalTrials.gov, number NCT02662231.FindingsBetween Jan 4, 2016, and July 31, 2016, 13 265 records were submitted for analysis. 12 539 patients from 343 hospitals in 66 countries were included. 7339 (58·5%) patient were from high-HDI countries (193 hospitals in 30 countries), 3918 (31·2%) patients were from middle-HDI countries (82 hospitals in 18 countries), and 1282 (10·2%) patients were from low-HDI countries (68 hospitals in 18 countries). In total, 1538 (12·3%) patients had SSI within 30 days of surgery. The incidence of SSI varied between countries with high (691 [9·4%] of 7339 patients), middle (549 [14·0%] of 3918 patients), and low (298 [23·2%] of 1282) HDI (p<0·001). The highest SSI incidence in each HDI group was after dirty surgery (102 [17·8%] of 574 patients in high-HDI countries; 74 [31·4%] of 236 patients in middle-HDI countries; 72 [39·8%] of 181 patients in low-HDI countries). Following risk factor adjustment, patients in low-HDI countries were at greatest risk of SSI (adjusted odds ratio 1·60, 95% credible interval 1·05–2·37; p=0·030). 132 (21·6%) of 610 patients with an SSI and a microbiology culture result had an infection that was resistant to the prophylactic antibiotic used. Resistant infections were detected in 49 (16·6%) of 295 patients in high-HDI countries, in 37 (19·8%) of 187 patients in middle-HDI countries, and in 46 (35·9%) of 128 patients in low-HDI countries (p<0·001).InterpretationCountries with a low HDI carry a disproportionately greater burden of SSI than countries with a middle or high HDI and might have higher rates of antibiotic resistance. In view of WHO recommendations on SSI prevention that highlight the absence of high-quality interventional research, urgent, pragmatic, randomised trials based in LMICs are needed to assess measures aiming to reduce this preventable complication.FundingDFID-MRC-Wellcome Trust Joint Global Health Trial Development Grant,...
Objective We aimed to investigate the relationship between the isolated intrauterine growth restriction (IUGR) and maternal serum gasdermin D (GSDMD) concentration. Materials and methods This cross-sectional study was conducted with 80 pregnant women who applied to the Umraniye Training and Research Hospital Gynecology and Obstetrics Clinic between January 2022 and May 2022. The IUGR group consisted of 40 pregnant women diagnosed with IUGR in the third trimester, and the control group consisted of 40 healthy pregnant women matched with the IUGR group in terms of age and BMI. Demographic characteristics, ultrasound findings, and neonatal outcomes were noted. The two groups were compared in terms of maternal serum GSDMD concentrations. Results Both groups were similar in terms of demographic characteristics. Fetal biometric measurements were found to be significantly lower in the IUGR group compared to the control group, and umbilical artery Doppler PI and SD were found to be higher. Gestational age, newborn birth weight, birth height, and Apgar scores were significantly lower and NICU admission rate was higher in the IUGR group. Gestational age at blood sampling for GSDMD was similar in both groups (p=0.805). While maternal serum GSDMD concentration was 11.14 ng/ml in the IUGR group, it was 6.66 ng/ml in the control group (p=0.000). ROC analysis was performed to determine the value of GSDMD concentration in terms of IUGR estimation. AUC analysis of GSDMD for IUGR estimation was 0.88 (p<.001, 95% CI=0.80–0.95). The optimal cutoff value for GSDMD concentration was determined as 8.84 ng/ml with 80% sensitivity and 75% specificity. Conclusion Maternal serum GSDMD concentrations were found to be higher in pregnant women whose pregnancy was complicated by isolated IUGR. We think that high GSDMD concentrations may be a reflection of increased GSDMD-mediated pyroptosis in placental tissue in isolated IUGR cases.
Objective Thrombotic thrombocytopenic purpura is a thrombotic microangiopathic condition characterized by hemolytic anemia, thrombocytopenia, neurologic abnormalities, fever and renal dysfunction. Thrombotic microangiopathies such as preeclampsia and HELLP syndrome are pregnancy-specific, whereas others such as thrombotic thrombocytopenic purpura (TTP) and hemolytic uremic syndrome are not. In this report, we present a case at which we identified a novel mutation which led to a significant reduction of ADAMTS13 activity. Case(s) A nulliparous pregnant woman of 32-year-old presenting with epigastric pain, hypertension and low platelet count was first suspected of HELLP syndrome, but was diagnosed with congenital TTP after delivery. Conclusion HELLP syndrome co-existed with undiagnosed TTP in this case. We strive to have sufficient awareness in order to distinguish these two pathologies from each other on an antenatal basis, because the causes of the managements are entirely different.
