A predictive model for mortality risk in <i>Shewanella</i>-related SSI patients was established using plasma interleukin-6 (IL-6) levels combined with the Howell-PIRO scoring system. <b><i>Results:</i></b> Over the past 10 years, 45 strains of <i>Shewanella</i> were isolated from specimens such as bile, drainage fluid, and whole blood in patients with digestive tract SSIs. Among them, 21 of 45 (46.67%) patients underwent malignant tumor resection of the digestive system, 14 of 45 (31.11%) underwent endoscopic retrograde cholangiopancreatography (ERCP) common bile duct exploration or the stone removal, and seven of 45 (15.56%) were trauma repair patients with fractures and abdominal injuries. Among the 45 <i>Shewanella</i>-related SSI patients, 10 died within 30 days of infection, six cases involved infections with more than two other types of bacteria. The combined use of IL-6 and Howell-PIRO scores for mortality risk assessment yielded an receiver operating characteristic (ROC) curve with an area under the curve (AUC) of 0.9350, a positive predictive value of 92.71%, a negative predictive value of 94.58%, a diagnostic sensitivity of 95.35%, and a diagnostic specificity of 92.14%-all higher than the model using IL-6 or Howell-PIRO scores alone. <b><i>Conclusions:</i></b> We found that residents in coastal areas faced an increased risk of <i>Shewanella</i>-related SSI. Moreover, the higher the number of concurrent microbial infections occurring alongside <i>Shewanella</i>-related SSI, the greater the mortality rate among patients. The combined application of plasma IL-6 levels and the Howell-PIRO scoring system is beneficial for assessing patient mortality risk and guiding timely and proactive clinical interventions.</p>","PeriodicalId":22109,"journal":{"name":"Surgical infections","volume":null,"pages":null},"PeriodicalIF":2.0,"publicationDate":"2024-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140869283","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aimed to evaluate invasive candidiasis (IC) risk factors in critically ill patients undergoing surgery. Patients and Methods: We retrospectively reviewed the medical records of 583 patients who underwent emergency surgery for complicated intra-abdominal infections between January 2016 and December 2021. Patients were divided into two groups according to the presence or absence of IC during their hospital stay. IC was defined as culture-proven candidemia and intra-abdominal candidiasis. Results: This study included 373 patients for the final analysis, of whom 320 were discharged without IC (IC absent group) and 53 presented with IC (IC present group) during their hospital stay. The IC present group showed a higher in-hospital mortality rate (35.8 vs. 8.8%; p < 0.001), with 66.0% of the patients diagnosed within 10 days, whereas only 6.5% were diagnosed beyond 20 days after admission. Stomach (odds ratio [OR], 4.188; 95% confidence interval [CI], 1.204-14.561; p = 0.024) and duodenum (OR, 7.595; 95% CI, 1.934-29.832; p = 0.004) as infection origin, higher Acute Physiology and Chronic Health Evaluation II (APACHE II) score (OR, 1.097; 95% CI, 1.044-1.152; p < 0.001), and lower initial systolic blood pressure (OR, 0.983; 95% CI, 0.968-0.997; p = 0.018) were risk factors of IC after emergency gastrointestinal surgery. Conclusions: Patients who had stomach and duodenum as infection origin, higher APACHE II scores, and lower initial systolic blood pressure had a higher risk of developing IC during their hospital stay after emergency gastrointestinal surgery. Prophylactic antifungal agents can be carefully considered for critically ill patients with these features.","PeriodicalId":22109,"journal":{"name":"Surgical infections","volume":null,"pages":null},"PeriodicalIF":2.0,"publicationDate":"2024-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140690431","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The purpose of this study was to define the best ultrasound signs that could ultimately improve the diagnostic accuracy of ultrasound for diagnosing pediatric acute appendicitis, and to differentiate between simple appendicitis and complicated appendicitis. Patients and Methods: After approval by our Institutional Review Board, a prospective study was carried out from January 1, 2022, to July 31, 2023, in a pediatric emergency department. We included all patients aged under 14 years with suspected appendicitis and ultrasound-visualized appendix. Results: A total of 550 patients presented with suspected appendicitis during the study period. Of these children, 411 had an ultrasound-visualized appendix. Our patients' mean age was 9.4 years. The best positive predictive value of ultrasound was found for appendiceal diameter ≥7.5 mm. The combination of an appendiceal diameter <6 mm and the lack of peri-appendiceal free fluid on ultrasound rules out the diagnosis of appendicitis. The best diagnostic accuracy of ultrasound, which was 92%, was achieved for appendix diameters ≥6.5 mm. The sonographic sign giving the best ultrasound accuracy for diagnosing complicated appendicitis was an appendix diameter ≥9 mm. Conclusions: In conclusion, our present study demonstrated that appendiceal diameter ≥6.5 mm is the gold standard for diagnosing appendicitis in pediatric patients. The combination of an appendiceal diameter <6 mm and the lack of peri-appendiceal free fluid on ultrasound would rule out appendicitis.","PeriodicalId":22109,"journal":{"name":"Surgical infections","volume":null,"pages":null},"PeriodicalIF":2.0,"publicationDate":"2024-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140698136","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To help in early detection of high-risk patients, we aimed to systematically review factors associated with mortality from FG. Patients and Methods: Searches were conducted in PubMed, Embase and Scopus. In our review, a minimum of five patients were required and this was to exclude studies with exceedingly small sample sizes, such as case reports and small case series, with minimal relevance in comparison to larger scale studies. Patient characteristics, causative microbes, anatomic areas of infection, presence of comorbidities, severity scores, causes of FG, and complications were extracted and compared to identify factors related to mortality. Results: A total of 57 studies were included in the review. Across 3,646 study participants, the mortality rate of FG was 20.41%. The mean age of non-survivors was 61.27 years. There were more total male deaths, however, the mortality rate was higher in females. Diabetes mellitus was the most common comorbidity in those who died, but the highest mortality rate was seen in HIV patients (54.17%). Mortality rates did not differ widely among antibiotic agents. Regarding causative organisms, fungal infections had the highest rates of mortality (68.18%) and the most common microbe leading to death was Escherichia coli. Conclusions: Female gender, comorbidities, anatomic distribution, development of sepsis, and fungal infection all increased risk for mortality. Early identification of risk factors, and provision of appropriate treatment are crucial in reducing mortality rates of high-risk patients with FG.","PeriodicalId":22109,"journal":{"name":"Surgical infections","volume":null,"pages":null},"PeriodicalIF":2.0,"publicationDate":"2024-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140697825","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
