Early postoperative systemic inflammatory response as predictor of anastomotic leakage after esophagectomy: a systematic review and meta-analysis.

BACKGROUND AND PURPOSE: Postesophagectomy anastomotic leakage occurs in up to 16% of patients and is the main cause of morbidity and mortality. The leak severity is determined by the extent of contamination and the degree of sepsis, both of which are related to the time from onset to treatment. Early prediction based on inflammatory biomarkers such as C-reactive protein (CRP) levels, white blood cell counts, albumin levels, and combined Noble-Underwood (NUn) scores can guide early management. This review aimed to determine the diagnostic accuracy of these biomarkers. METHODS: This study was designed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines and registered in the PROSPERO (International Prospective Register of Systematic Reviews) database. Two reviewers independently conducted searches across PubMed, MEDLINE, Web of Science, and Embase. Sources of bias were assessed, and a meta-analysis was performed. RESULTS: Data from 5348 patients were analyzed, and 13% experienced leakage. The diagnostic accuracy of the serum biomarkers was analyzed, and pooled cutoff values were identified. CRP levels were found to have good diagnostic accuracy on days 2 to 5. The best discrimination was identified on day 2 for a cutoff value < 222 mg/L (area under the curve = 0.824, sensitivity = 81%, specificity = 88%, positive predictive value = 38.6%, and negative predictive value = 98%). A NUn score of >10 on day 4 correlated with poor diagnostic accuracy. CONCLUSION: The NUn score failed to achieve adequate accuracy. CRP seems to be the only valuable biomarker and is a negative predictor of postesophagectomy leakage. Patients with a CRP concentration of <222 mg/L on day 2 are unlikely to develop a leak, and patients can safely proceed through their enhanced recovery after surgery protocol. Patients with a CRP concentration of <127 mg/L on day 5 can be safely discharged when clinically possible.

Risk of Systemic Inflammatory Response Syndrome Following Preoperative Glucocorticoids Administration in Patients After Percutaneous Nephrolithotomy: A Retrospective Cohort Study.

INTRODUCTION: Systemic inflammatory response syndrome (SIRS) is one of the most serious complications in patients undergoing percutaneous nephrolithotomy (PCNL). Although glucocorticoids are increasingly used during PCNL, few studies have been concerned about the association between glucocorticoids and postoperative SIRS. The study aims to explore whether preoperative use of glucocorticoids is associated with SIRS after PCNL. METHODS: A total of 1259 patients who underwent PCNL between January 2015 and April 2021 were enrolled in the retrospective cohort study. Risk factors for post-PCNL SIRS were identified by univariate and multivariate regression analysis. To further explore the association between preoperative administration of glucocorticoids and SIRS, 113 pairs of patients were matched for the confounding factors using propensity score matching (PSM) analysis. The odds ratios (OR) and 95 % confidence intervals (CI) for the above variables were analyzed. RESULTS: The incidence of SIRS after PCNL was 9.6 % (121/1259) and the patients who suffered from postoperative SIRS had longer hospital stays and higher hospital costs (all p < 0.05). Multivariate logistic regression analysis indicated that female, preoperative leukocyte count, insertion of central vein catheter, serum albumin, preoperative high-sensitive C-reactive protein/albumin ratio, preoperative transfusion, preoperative administration of glucocorticoids were independent risk factors for SIRS (all p < 0.05). After minimization, the effects of confounding factors by PSM, preoperative administration of glucocorticoids was significantly correlated with SIRS in patients after PCNL (OR=2.44, 95 %CI: 1.31-4.55, p = 0.005). CONCLUSION: Preoperative administration of glucocorticoids is an independent risk factor for SIRS in patients undergoing PCNL.

Systemic inflammatory response syndrome (SIRS) is a frequent and severe complication in patients underwent percutaneous nephrolithotomy (PCNL), which can be challenging to diagnose early, potentially leading to delayed treatment. Identifying SIRS risk factors and promptly treating high-risk patients is crucial. Glucocorticoids are commonly used to prevent SIRS in clinical practice, and this study aims to investigate whether preoperative glucocorticoid administration is associated with SIRS after PCNL. In total, 1259 patients underwent PCNL and were enrolled in the study. The study utilized both propensity score matching (PSM) analysis and regression analysis to identify risk factors for post-PCNL SIRS. The incidence of SIRS after PCNL was 9.6 % in the study and patients with postoperative SIRS had longer hospital stays and higher hospital costs. After minimizing the potential influence of confounding factors through the use of PSM, we found a significant association between the preoperative use of glucocorticoids and the occurrence of SIRS in patients undergoing PCNL. Based on our analysis, we can conclude that the preoperative administration of glucocorticoids represents an independent risk factor for the development of SIRS in these patients.

Description of a national, multi-center registry of patients with sickle cell disease and SARS-CoV-2 infection: Data from the Pediatric COVID-19 United States Registry.

Children with sickle cell disease (SCD) are at risk of complications from viral infections, including SARS-CoV-2. We present the clinical characteristics and outcomes of pediatric patients with SCD from the Pediatric COVID-19 United States Registry who developed acute COVID-19 due to SARS-CoV-2 infection (n = 259) or multisystem inflammatory syndrome in children (MIS-C; n = 4). Nearly half of hospitalized children with SCD and SARS-CoV-2 infection required supplemental oxygen, though children with SCD had fewer intensive care (ICU) admissions compared to the general pediatric and immunocompromised populations. All registry patients with both SCD and MIS-C required ICU admission. Children with SCD are at risk of severe disease with SARS-CoV-2 infection, highlighting the importance of vaccination in this vulnerable population.

Postoperative antibiotic prophylaxis for percutaneous nephrolithotomy and risk of infection: a systematic review and meta-analysis.

PURPOSE: The aim of this study is to perform a high-quality meta-analysis using only randomized controlled trials (RCT) to better define the role of postoperative antibiotics in patients undergoing percutaneous nephrolithotomy (PCNL). MATERIALS AND METHODS: A literature search for RCTs in EMBASE, PubMed, and Web of Science up to May 2023 was conducted following the PICO framework: Population-adult patients who underwent PCNL; Intervention-postoperative antibiotic prophylaxis until nephrostomy tube withdrawal; Control-single dose of antibiotic during the induction of anesthesia; and Outcome-systemic inflammatory response syndrome (SIRS) or sepsis and fever after PCNL. The protocol was registered on the PROSPERO database (CRD42022361579). We calculated odds ratios (OR) and 95% confidence intervals (CI). A random-effects model was employed, and the alpha risk was defined as < 0.05. RESULTS: Seven articles, encompassing a total of 629 patients, were included in the analysis. The outcome of SIRS or sepsis was extracted from six of the included studies, while the outcome of postoperative fever was extracted from four studies. The analysis revealed no statistical association between the use of postoperative antibiotic prophylaxis until nephrostomy tube withdrawal and the occurrence of SIRS/sepsis (OR 1.236, 95% CI 0.731 - 2.089, p=0.429) or fever (OR 2.049, 95% CI 0.790 - 5.316, p=0.140). CONCLUSION: Our findings suggest that there is no benefit associated with the use of postoperative antibiotic prophylaxis until nephrostomy tube withdrawal in patients undergoing percutaneous nephrolithotomy (PCNL). We recommend that antibiotic prophylaxis should be administered only until the induction of anesthesia in PCNL.

Prolonged Systemic Inflammatory Response Syndrome After Cardiac Surgery.

OBJECTIVES: Cardiac surgery induces systemic inflammatory response syndrome (SIRS), leading to higher morbidity and mortality. There are no individualized predictors for worse outcomes or biomarkers for the multifactorial, excessive inflammatory response. The interest of this study was to evaluate whether a systematic use of the SIRS criteria could be used to predict postoperative outcomes beyond infection and sepsis, and if the development of an exaggerated inflammation response could be observed preoperatively. DESIGN: The study was observational, with prospectively enrolled patients. SETTING: This was a single institution study in a hospital setting combined with laboratory findings. PARTICIPANTS: The study included a cohort of 261 volunteer patients. INTERVENTIONS: Patients underwent cardiac surgery with cardiopulmonary bypass, and were followed up to 90 days. Biomarker profiling was run preoperatively. MEASUREMENTS AND MAIN RESULTS: Altogether, 17 of 261 (6.4%) patients had prolonged SIRS, defined as fulfilling at least 2 criteria on 4 consecutive postoperative days. During hospitalization, postoperative atrial fibrillation (POAF) was found in 42.2% of patients, and stroke and transient ischemic attack in 3.8% of patients. Prolonged SIRS was a significant predictor of POAF (odds ratio [OR] 4.5, 95% CI 1.2-17.3), 90-day stroke (OR 4.5, 95% CI 1.1-18.0), and mortality (OR 10.7, 95% CI 1.7-68.8). Biomarker assays showed that preoperative nerve growth factor and interleukin 5 levels were associated with prolonged SIRS (OR 5.6, 95%, CI 1.4-23.2 and OR 0.7, 95%, CI 0.4-1.0, respectively). CONCLUSIONS: Nerve growth factor and interleukin 5 can be used to predict prolonged systemic inflammatory response, which is associated with POAF, stroke, and mortality.

Effects of high-intensity inspiratory muscle training on systemic inflammatory response in cardiac surgery - A randomized clinical trial.

PURPOSE: Preoperative inspiratory muscle training reduces the incidence of postoperative pulmonary complications after cardiac surgery, but training protocols vary widely in terms of intensity. Currently, the mechanisms underlying the effectiveness of this practice are not known. The purpose of the present study is to determine whether preoperative high-intensity inspiratory muscle training (HI-IMT) modulates the perioperative systemic inflammatory response in cardiac surgery patients. METHODS: Participants awaiting surgical aortic valve replacement were randomized to 3 to 6 weeks preoperative home-based HI-IMT or same duration low-intensity inspiratory muscle training (LI-IMT). The primary outcome was the preoperative value of the soluble tumor necrosis factor receptor 1 (sTNFR1). Secondary outcomes assessed perioperative evolution of the cytokines: sTNFR1, Tumor necrosis factor-α, Interleukin (IL)-6, IL-8, IL10, IL1ß, and their combined z-score; reflecting post-training and postoperative inflammatory response. Perioperative pulmonary function and postoperative clinical outcomes were collected. RESULTS: Between February 2018 and March 30, 2019 patients were randomized, to HI-IMT or LI-IMT. There were no differences between the groups in terms of baseline characteristics. The median (IQR) training duration was 34 (28-44) days. After training, the median (IQR) predicted maximal inspiratory pressure was higher in the HI-IMT vs LI-IMT group (119 (96-142%) vs 97 (81-107%); p = .04) Levels of the sTNFR1 cytokine increased during training in the HI-IMT group, pre vs post training (Median (IQR) 1073 (920; 1219) vs 1172 (965; 1368) ng/L; p = .03). The 24-h postoperative global inflammatory score was lower in the HI-IMT than in the LI-IMT group (Median (IQR), -0.37 (-0.62, 0.03) vs -0.10 (-0.17, 0.49), p = .04). Global inflammatory scores were not different at other time points. There were no significant differences between the groups in post-operative pulmonary function and postoperative clinical outcome. CONCLUSION: High intensity inspiratory muscle training shows immunomodulatory properties. These properties could explain why preoperative inspiratory muscle training can lead to lung protection after cardiac surgery.

Impact of endoprosthesis type on inflammatory response in patients undergoing endoscopic drainage of pancreatic fluid collections.

OBJECTIVE: To study the impact of endoprosthesis type on inflammatory response in patients undergoing endoscopic ultrasound (EUS)-guided drainage of pancreatic fluid collections (PFC). METHODS: Patients undergoing EUS-guided PFC drainage and treated using lumen-apposing metal stents (LAMS) or plastic endoprostheses constituted the study cohort. The primary outcome was the presence of systemic inflammatory response syndrome (SIRS) after index intervention. Secondary outcomes were persistent organ failure, new onset organ failure, duration of hospitalization, and treatment success. RESULTS: In all, 303 patients were treated using LAMS (n = 247) or plastic stents (n = 56). At 48 h postintervention, the presence of SIRS (25.0 vs. 14.2%, P = 0.047), new onset SIRS (10.0 vs. 1.8%, P = 0.017), and new organ failure (5.4 vs. 0.4%, P = 0.003) were significantly higher in the plastic stent cohort compared to LAMS. On multivariable logistic regression analysis, the use of plastic stents (odds ratio [OR] 2.7, 95% confidence interval [CI] 1.2-6.0, P = 0.014), patients receiving high-acuity care (OR 5.1, 95% CI 2.5-10.4, P < 0.001) and the presence of ≥33% of necrosis (OR 4.5, 95% CI 2.0-10.0, P < 0.001) were significantly associated with the presence of SIRS or new organ failure. While there was no significant difference in treatment success (96.4 vs. 95.5%, P = 0.77), duration of hospitalization was significantly longer for the plastic stent cohort (mean [standard deviation] 12.5 [17.8] vs. 7.9 [10.1] days, P = 0.009). CONCLUSIONS: Use of plastic stents as compared to LAMS was associated with a higher proportion of SIRS and new organ failure that prolonged hospital stay. Therefore, placement of LAMS is recommended in sick patients and those with ≥33% necrosis to minimize inflammatory response.

Skin manifestations in children with MIS-C and COVID-19: a narrative review.

This review aims to highlight the diverse skin manifestations in children and adolescents with COVID induced multisystem inflammatory syndrome in children (MIS-C). The symptoms of COVID-19 can vary greatly in severity between different age groups. Although most children infected with SARS-CoV-2 experience either no symptoms or only mild symptoms, some reported cases of severely affected children with a clinical presentation similar to incomplete Kawasaki disease have led to the definition of a new condition called MIS-C. MIS-C can involve multiple organs, including the skin, and may pose a life-threatening risk to affected children. Such cases highlight the need for continuous research into the possible skin manifestations associated with COVID-19 in pediatric populations to aid in early diagnosis and prompt treatment. We conducted a search of PubMed, Scopus, and ScienceDirect databases for studies published up until October 1, 2022. Three reviewers independently examined each study, and a fourth reviewer resolved any disagreements. A narrative review of all relevant papers was conducted. We present an overview of the clinical presentation, pathophysiology, diagnosis, and treatment of the various skin manifestations in children and adolescents with COVID-19 or MIS-C. The skin manifestations of COVID-19 and MIS-C can be diverse and are frequently overlooked. It is important to conduct further research to better understand the impact of this disease on children to provide appropriate care for these at-risk populations.

The relationship between systemic inflammatory response, screen detection and outcome in colorectal cancer.

AIM: A raised systemic inflammatory response correlates with poorer colorectal cancer (CRC) outcomes. Faecal immunochemical test bowel screening aims to detect early-stage disease. We assessed the relationship between systemic inflammatory response, screen detection and CRC survival. METHOD: A retrospective, observational cohort study compared screen-detected and non-screen-detected CRC patients undergoing resection. Systemic inflammatory response was measured using lymphocyte/monocyte, neutrophil/lymphocyte and platelet/lymphocyte ratios (LMR, NLR, PLR). Covariables were compared using χ2 testing and survival with Cox regression. RESULTS: A total of 761 patients were included (326 screen-detected, 435 non-screen-detected). Screen-detected patients had lower systemic inflammatory response: low (<2.4) LMR (28.8% vs. 44.6%; P < 0.001), moderate (3-5) or high (>5) NLR (26.1% vs. 30.6%, P < 0.001; and 7.7% vs. 19.5%, P < 0.001) and high (>150) PLR (47.2% vs. 64.6%; P < 0.001). Median follow-up was 63 months. On univariate analysis, non-screen detection (hazard ratio [HR] 2.346, 95% CI 1.687-3.261; P < 0.001), advanced TNM (P < 0.001), low LMR (HR 2.038, 95% CI 1.514-2.742; P < 0.001), moderate NLR (HR 1.588, 95% CI 1.128-2.235; P = 0.008), high NLR (HR 2.382, 95% CI 1.626-3.491; P < 0.001) and high PLR (HR 1.827, 95% CI 1.326-2.519; P < 0.001) predicted poorer overall survival (OS). Non-screen detection (HR 2.713, 95% CI 1.742-4.226; P < 0.001), TNM (P < 0.001), low LMR (HR 1.969, 95% CI 1.340-2.893; P < 0.001), high NLR (HR 2.368, 95% CI 1.448-3.875; P < 0.001) and high PLR (HR 2.110, 95% CI 1.374-3.240; P < 0.001) predicted poorer cancer-specific survival (CSS). On multivariate analysis, non-screen detection (HR 1.698, 95% CI 1.152-2.503; P = 0.008) and low LMR (HR 1.610, 95% CI 1.158-2.238; P = 0.005) independently predicted poorer OS. Non-screen detection (HR 1.847, 95% CI 1.144-2.983; P = 0.012) and high PLR (HR 1.578, 95% CI 1.018-2.444; P = 0.041) predicted poorer CSS. CONCLUSION: Screen-detected CRC patients have a lower systemic inflammatory response. Non-screen detection and systemic inflammatory response (measured by LMR and PLR respectively) were independent predictors of poorer OS and CSS.

Incidence of systemic inflammatory response syndrome and patient outcome following transcatheter edge-to-edge mitral valve repair.

OBJECTIVES: Systemic inflammatory response syndrome (SIRS) is a common finding after cardiovascular interventions. Data on the incidence of SIRS and its impact on outcome in patients undergoing transcatheter edge-to-edge mitral valve repair (MV-TEER) for mitral regurgitation (MR) is lacking. METHODS: From January 2013 to December 2020, 373 patients with moderate or severe MR undergoing MV-TEER were included. SIRS was defined as at least two of the following criteria within 48 h after the procedure: leucocyte count > 12.0 or < 4.0 × 109/l, respiratory rate > 20 breaths per minute or PaCO2 ≤ 4.3 kPa/32 mmHg, heart rate > 90 bpm and temperature > 38.0 °C or < 36.0 °C. The primary endpoint was 3-years all-cause mortality. RESULTS: SIRS was observed in 49.6% (185/373) of patients. Patients who developed SIRS presented more frequently with NYHA III/IV at baseline [SIRS: 82.4% (149/185) vs. no SIRS: 79.0% (147/188); p = 0.029]. Patients who developed SIRS spent more days on ICU (p < 0.001) and overall length of stay was longer (p < 0.001). Relevant residual MR, defined as MR ≥ III in-hospital, was present more often in patients who developed SIRS [SIRS: 11.3% (20/177) vs. no SIRS: 3.93% (7/178), p = 0.036]. At 3 years, all-cause mortality in the entire population was 33.5% (125/373) with an increased all-cause mortality in patients with SIRS compared to patients without SIRS (HR 1.49, [CI 95% 1.04, 2.13]; p = 0.0264). In the multivariate analysis development of SIRS (HR 1.479 [CI 95% 1.016, 2.154]; p = 0.041) was identified as predictor for 3-years all-cause mortality. CONCLUSIONS: SIRS is a common finding after MV-TEER occurring in approximately half of patients. SIRS after MV-TEER was associated with a longer in-hospital stay. In addition, we observed an increased 3-years all-cause mortality in patients with SIRS.

Can Perioperative Antibiotic Choice Impact Rates of Infectious Complications After Percutaneous Nephrolithotomy? A Single-Blind, Prospective Randomized Trial.

Objective: National guidelines recommend periprocedural antibiotics before percutaneous nephrolithotomy (PCNL), yet it is not clear which is superior. We conducted a randomized trial to compare two guideline-recommended antibiotics: ciprofloxacin (cipro) vs cefazolin, on PCNL outcomes, focusing on the development of systemic inflammatory response syndrome (SIRS) criteria. Methods: Adult patients who were not considered high risk for surgical or infectious complications and undergoing PCNL were randomized to receive either cipro or cefazolin perioperatively. All had negative preoperative urine cultures. Demographic and perioperative data were collected, including SIRS criteria, intraoperative urine culture, duration of hospitalization, and need for intensive care. SIRS is defined by ≥2 of the following: body temperature <96.8°F or >100.4°F, heart rate >90 bpm, respiratory rate >20 per minute, and white blood cell count <4000 or >12,000 cells/mm3. Results: One hundred forty-seven patients were enrolled and randomized (79 cefazolin and 68 cipro). All preoperative characteristics were similar (p > 0.05), except for mean age, which was higher in the cipro group (64 vs 57 years, p = 0.03). Intra- and postoperative findings were similar, with no difference between groups (p > 0.05), except a longer mean hospital stay in the cefazolin group (2 hours longer, p = 0.02). There was no difference between SIRS episodes in both univariate and multivariate analyses. Conclusions: Despite the relatively broader coverage for urinary tract pathogens with ciprofloxacin, this prospective randomized trial did not show superiority over cefazolin. Our findings therefore support two appropriate options for perioperative antibiotic prophylaxis in patients undergoing PCNL who are nonhigh risk for infectious complications.

A new method for predicting SIRS after percutaneous transhepatic gallbladder drainage.

The occurrence of systemic inflammatory response after percutaneous transhepatic gallbladder drainage brings great risks to patients and is one of the challenges faced by clinicians. Therefore, it is of great significance to find a suitable prediction method for clinicians to intervene early and reduce the transformation of serious complications. Easy-to-obtain and objectively measured clinical features were screened, and logistic regression was used to construct a prediction model. The predictive ability of the model was evaluated by using the receiver operating characteristic curve and the decision curve in the validation set and the training set, respectively. Nine clinical features (CRP, Fever, DBIL, Obstruction, Bile properties, PCT, Length, Width, and Volume factor) were used to construct the prediction model, and the validation results showed that the prediction model had good performance in the training set (AUC = 0.83) and the validation set (AUC = 0.81). The decision curve also showed that the predictive ability of the model incorporating nine clinical features is better than that of a single clinical feature. The model we constructed can accurately predict the occurrence of SIRS, which can guide clinicians to take treatment measures and avoid the deterioration of complications.

A case of multisystem inflammatory syndrome in children: A case report.

RATIONALE: Multisystemic inflammatory syndrome is a syndrome of multisystem involvement caused by a novel coronavirus infection that can lead to cardiogenic shock and death in children. PATIENT CONCERNS: A 4-year-old girl was diagnosed with multiple organ and multiple system involvement after Kawasaki disease. DIAGNOSIS: Novel coronavirus infection-associated multisystem inflammatory syndrome in children was considered. INTERVENTIONS: The patients received aspirin, methylprednisolone and gammaglobulin to treat multisystem inflammatory syndrome. OUTCOMES: After treatment, the child recovered and was discharged from the hospital. LESSONS: Multisystem inflammatory syndrome is often mistaken for Kawasaki disease, fortunately, their treatments are similar, the purpose of this case is to remind clinicians of the need for early management of children with multisystem failure following novel coronavirus infection, increase the detection rate, and save the life of the child.

Endothelial Microparticles: Markers of Inflammatory Response After Sutureless Valve Implantation.

INTRODUCTION: Systemic inflammatory response syndrome (SIRS) is related to increased circulating endothelial microparticles (EMP). OBJECTIVE: The aim of this study was to compare the plasma concentration of EMP between patients undergoing aortic valve replacement with conventional bioprosthesis implantation and Perceval™ S (LivaNova) and to evaluate its impact on the inflammatory response in the short-term follow-up. METHODS: This is a randomized clinical trial with 24 patients submitted to isolated aortic valve replacement divided into two groups: Perceval™ S (Group P) and conventional bioprostheses (Group C). Incidence of severe SIRS (three or more criteria) in the first 48 hours postoperatively, EMP release profile, interleukins (IL) 6 and 8, C-reactive protein, and procalcitonin were analyzed preand postoperatively at 24 hours and three months. RESULTS: There were 24 patients (12 in each group), mean age was 69.92±5.17 years, 83.33% were female, the incidence of severe SIRS was 66.7% and 50% in groups C and P, respectively (P=0.68), and EMP showed a significant increase in the 24-hour postoperative period (P≤0.001) and subsequent decrease in the three-month postoperative period (P≤0.001), returning to baseline levels. For IL-6 and IL-8, there was a greater increase in group C at 24 hours postoperatively (P=.0.02 and P<0.001). CONCLUSION: The incidence of severe SIRS was similar in both groups, with significantly higher levels of IL-6 and IL-8, at the 24-hour postoperative period, in group C, however with higher levels of EMP in group P, and subsequent return to baseline levels at the three-month postoperative period in both groups.

Clinical usefulness of scoring systems to predict severe acute pancreatitis: A systematic review and meta-analysis with pre and post-test probability assessment.

BACKGROUND: Scoring systems for severe acute pancreatitis (SAP) prediction should be used in conjunction with pre-test probability to establish post-test probability of SAP, but data of this kind are lacking. OBJECTIVE: To investigate the predictive value of commonly employed scoring systems and their usefulness in modifying the pre-test probability of SAP. METHODS: Following PRISMA statement and MOOSE checklists after PROSPERO registration, PubMed was searched from inception until September 2022. Retrospective, prospective, cross-sectional studies or clinical trials on patients with acute pancreatitis defined as Revised Atlanta Criteria, reporting rate of SAP and using at least one score among Bedside Index for Severity in Acute Pancreatitis (BISAP), Acute Physiology and Chronic Health Examination (APACHE)-II, RANSON, and Systemic Inflammatory Response Syndrome (SIRS) with their sensitivity and specificity were included. Random effects model meta-analyses were performed. Pre-test probability and likelihood ratio (LR) were combined to estimate post-test probability on Fagan nomograms. Pooled severity rate was used as pre-test probability of SAP and pooled sensitivity and specificity to calculate LR and generate post-test probability. A priori hypotheses for heterogeneity were developed and sensitivity analyses planned. RESULTS: 43 studies yielding 14,116 acute pancreatitis patients were included: 42 with BISAP, 30 with APACHE-II, 27 with Ranson, 8 with SIRS. Pooled pre-test probability of SAP ranged 16.6%-25.3%. The post-test probability of SAP with positive/negative score was 47%/6% for BISAP, 43%/5% for APACHE-II, 48%/5% for Ranson, 40%/12% for SIRS. In 18 studies comparing BISAP, APACHE-II, and Ranson in 6740 patients with pooled pre-test probability of SAP of 18.7%, post-test probability when scores were positive was 48% for BISAP, 46% for APACHE-II, 50% for Ranson. When scores were negative, post-test probability dropped to 7% for BISAP, 6% for Ranson, 5% for APACHE-II. Quality, design, and country of origin of the studies did not explain the observed high heterogeneity. CONCLUSIONS: The most commonly used scoring systems to predict SAP perform poorly and do not aid in decision-making.

Preoperative hs-CRP/HDL ratio is associated with increased risk for postoperative SIRS in elderly patients: a retrospective cohort study.

BACKGROUND: Systemic inflammatory response syndrome (SIRS) greatly affects postoperative lives of afflicted aged patients. This study aimed to determine whether preoperative high hs-CRP/HDL ratio (CHR) was associated with an increased risk of postoperative SIRS in the elderly population. METHODS: This retrospective cohort study included data on patients aged ≥ 65 years who underwent general anesthesia surgery at two clinical centers between January 2015 and September 2020. The primary exposure was preoperative CHR which was divided into two groups (≤ 12.82 and > 12.82) based on its normal range in our hospital, and the primary outcome was the incidence of postoperative SIRS. Targeted maximum likelihood estimation analyses were used to model the exposure-outcome relationship. RESULTS: The analysis included 5595 elderly patients, of whom 1410 (25.20%) developed SIRS within three postoperative days. Targeted maximum likelihood estimation analysis revealed that elderly patients with CHR > 12.82 vs. CHR ≤ 12.82 was associated with increased risk of postoperative SIRS (aOR = 1.40, 95% CI [1.33, 1.48], P < 0.001). Those results were consistent both in subgroup analyses and sensitivity analyses. Compared with patients with CHR ≤ 12.82, patients with CHR > 12.82 had a higher prevalence of postoperative SIRS (49.06% vs. 22.70%), postoperative in-hospital mortality (3.40% vs. 0.65%), a longer hospital stay after surgery [10 (IQR, 6-16) vs. 8 (IQR, 5-11) days] and higher direct medical cost [10070 (IQR, 6878-15577) vs. 7117 (IQR, 4079-10314) euros, all P < 0.001]. CONCLUSIONS: In elderly patients, preoperative CHR > 12.82 was significantly associated with a higher risk of postoperative SIRS.

[Multisystemic inflammatory syndrome in children after severe acute respiratory syndrome coronavirus 2 infection: a clinical analysis of four cases]. / æ–°åž‹å† çŠ¶ç— æ¯’æ„ŸæŸ“åŽå„¿ç«¥å¤šç³»ç»Ÿç‚Žç—‡ç»¼åˆå¾4例.

OBJECTIVES: To investigate the clinical features and treatment strategies of multisystemic inflammatory syndrome in children (MIS-C) after severe acute respiratory syndrome coronavirus 2 infection. METHODS: A retrospective analysis was performed on the medical data of four children with MIS-C who were admitted to the Department of Cardiology, Xuzhou Children's Hospital, Xuzhou Medical Universityfrom January to February 2023. RESULTS: All four children had multiple organ involvements and elevated inflammatory markers, with a poor response to standard therapy for Kawasaki disease after admission. Two children were treated with intravenous immunoglobulin therapy pulse therapy twice, and all four children were treated with glucocorticoids. The children had a good prognosis after the treatment. CONCLUSIONS: MIS-C often appears within 4-6 weeks or a longer time after severe acute respiratory syndrome coronavirus 2 infection, and anti-inflammatory therapy in addition to the standard treatment regimen for Kawasaki disease can help to achieve a favorable treatment outcome.

Fluoroquinolone-resistant Escherichia coli among the rectal flora is the predominant risk factor for severe infection after transrectal ultrasound-guided prostate biopsy: a prospective observational study.

BACKGROUND: Infection of the prostate gland following biopsy, usually with Escherichia coli, is a common complication, despite the use of antimicrobial prophylaxis. A fluoroquinolone (FQ) is commonly prescribed as prophylaxis. Worryingly, the rate of fluoroquinolone-resistant (FQ-R) E. coli species has been shown to be increasing. OBJECTIVE: This study aimed to identify risk factors associated with infection after transrectal ultrasound-guided prostate biopsy (TRUS-Bx). METHODS: This was a prospective study on patients undergoing TRUS-Bx in southeast Sweden. Prebiopsy rectal and urine cultures were obtained, and antimicrobial susceptibility and risk-group stratification were determined. Multivariate analyses were performed to identify independent risk factors for post-biopsy urinary tract infection (UTI) and FQ-R E. coli in the rectal flora. RESULTS: In all, 283 patients were included, of whom 18 (6.4%) developed post-TRUS-Bx UTIs. Of these, 10 (3.5%) had an UTI without systemic inflammatory response syndrome (SIRS) and 8 (2.8%) had a UTI with SIRS. Being in the medium- or high-risk groups of infectious complications was not an independent risk factor for UTI with SIRS after TRUS-Bx, but low-level FQ-resistance (minimum inhibitory concentration (MIC): 0.125-0.25 mg/L) or FQ-resistance (MIC > 0.5 mg/L) among E. coli in the faecal flora was. Risk for SIRS increased in parallel with increasing degrees of FQ-resistance. Significant risk factor for harbouring FQ-R E.coli was travelling outside Europe within the previous 12 months. CONCLUSION: The predominant risk factor for UTI with SIRS after TRUS-Bx was FQ-R E. coli among the faecal flora. The difficulty in identifying this type of risk factor demonstrates a need for studies on the development of a general approach either with rectal swab culture for targeted prophylaxis, or prior rectal preparation with a bactericidal agent such as povidone-iodine before TRUS-Bx to reduce the risk of FQ-R E. coli-related infection.

The First Case in Japan of Fulminant Myocarditis Due to Multisystem Inflammatory Syndrome in Children (MIS-C) That Required Mechanical Circulatory Support.

Multisystem inflammatory syndrome in children (MIS-C) is a novel hyperinflammatory syndrome that is associated with severe acute respiratory syndrome coronavirus 2 infections. Reports describing the mechanical circulatory support (MCS) and myocardial biopsy for fulminant myocarditis due to MIS-C are limited.A 13-year-old male patient with MIS-C underwent treatment, including immunosuppressive therapy and MCS devices, and managed to recover from pulseless electrical activity cardiac arrest.This is the first patient in Japan with MIS-C who required MCS devices in Japan. Appropriate and immediate treatment with immunosuppressive therapy and MCS devices is important.
