Association of time-averaged systemic immune-inflammation indices with in-hospital mortality after intracerebral hemorrhage: a retrospective study.

BACKGROUND: Systemic inflammation plays a central role in secondary brain injury following intracerebral hemorrhage (ICH). Although inflammatory indices such as the neutrophil-to-lymphocyte ratio (NLR), systemic immune-inflammation index (SII), and systemic inflammation response index (SIRI) are linked to poor outcomes, their associations with mortality are commonly assumed to be linear, potentially overlooking nonlinear patterns where mortality risk rises steeply at higher levels. METHODS: We conducted a retrospective study using the MIMIC-IV database, including 440 patients with non-traumatic ICH who were alive and remained in the ICU for at least 72 h after admission. Mean NLR, SII, and SIRI were calculated from measurements obtained during this period. Multivariable logistic regression and restricted cubic spline (RCS) analyses were applied to assess their independent and nonlinear associations with in-hospital mortality. Model discrimination and calibration were internally validated using 1,000 bootstrap resamples. RESULTS: The in-hospital mortality rate was 26.1%. After multivariable adjustment, NLR and SIRI remained independently associated with mortality. Patients in the highest SIRI quartile had the highest risk of death (aOR = 5.12; 95% CI: 2.57-12.24; p < 0.001). RCS analysis revealed a significant nonlinear association between SIRI and mortality (p-nonlinearity < 0.05), showing a steep risk increase at higher SIRI levels. Adding SIRI to the base model provided a modest improvement in discrimination (AUC 0.762 to 0.785, p = 0.045) and significantly improved risk reclassification (cNRI = 0.4778, p < 0.001; IDI = 0.0240, p = 0.0151). CONCLUSIONS: Among patients with ICH who met the 72-hour eligibility criterion, higher 72-hour average SIRI was independently associated with in-hospital mortality. As a time-averaged measure, SIRI should be interpreted as a dynamic marker integrating the initial inflammatory state and the early clinical course rather than as a purely baseline prognostic factor. Although adding SIRI to the base model modestly improved discrimination and risk reclassification, it should be considered a candidate prognostic marker requiring external validation before clinical application.

Clinical predictors of severe and fatal respiratory syncytial virus infection in adults and the elderly: A retrospective cohort study.

BACKGROUND: Respiratory syncytial virus (RSV) is increasingly recognized as a cause of severe respiratory illness in adults, especially the elderly and those with comorbidities. However, data on outcomes and risk factors for severe disease in this population remain limited. METHODS: We retrospectively analyzed 123 adult patients diagnosed with RSV infection at a tertiary center in Taiwan from 2015 to 2023. Clinical characteristics, laboratory data, detection of other pathogens, clinical course and outcome were reviewed. Multivariable logistic regression identified risk factors for severe RSV infection, including ICU admission and 30-day mortality. RESULTS: The mean age was 55.7 years; 50% were aged ≥60 years and 13% were ≥75 years. ICU admission occurred in 17%, with significant associations to viral coinfection and elevated C-reactive protein (CRP). Thirty-day mortality was 13%, and overall in-hospital mortality was 18%, all among patients with comorbidities. Independent predictors of 30-day mortality included late elderly (aOR 24.2, p = 0.03), high CRP > 11.5 mg/dL (aOR 16.4, p = 0.005) and thrombocytopenia < 34,103/μL (aOR 11.4, p = 0.01). CONCLUSION: Advanced age (≥75 years), high CRP, and severe thrombocytopenia are key predictors of mortality in adults RSV patients. These findings highlight the need for targeted prevention strategies, including vaccination, in high-risk populations.

Aneurysmal subarachnoid hemorrhage care in a middle-income public healthcare system: A real-world neurocritical care cohort.

BACKGROUND AND PURPOSE: Although aneurysm treatment capacity has expanded worldwide, outcomes after aneurysmal subarachnoid hemorrhage (aSAH) remain strongly influenced by neurocritical care (NCC) delivery, referral pathways, and access to specialized treatment. Contemporary data describing real-world aSAH care in resource-limited healthcare systems remain scarce. We aimed to characterize treatment patterns, NCC delivery, complications, and outcomes in a large Brazilian public referral center. METHODS: This retrospective cohort study included consecutive adults with confirmed aSAH admitted between June 2018 and March 2022 to a high-volume Brazilian tertiary referral center. Only patients admitted within five days of symptom onset were included. Demographic, clinical, radiological, treatment, complication, and outcome data were extracted from institutional records. Primary outcomes were in-hospital mortality and 3-month functional outcome assessed by the modified Rankin Scale (mRS). RESULTS: Seventy-four patients were included. Disease severity was high, with 45% presenting WFNS grades 4-5, 73% modified Fisher grade 4 hemorrhage, and 64% hydrocephalus. Endovascular treatment was performed in 73% of cases, and median time from admission to aneurysm treatment was 1 day. Despite early treatment capability, only 28% of patients were admitted to an ICU within 48 h, while 38% never received ICU care. Delayed cerebral ischemia occurred in 43%, radiologic vasospasm in 58%, ventriculitis in 22%, and infectious complications in 57%. External ventricular drainage was required in 42%, and vasoactive drugs were used in 85%. In-hospital mortality was 42%, and 66% had unfavorable 3-month outcomes (mRS 4-6). CONCLUSIONS: This real-world cohort highlights the substantial neurocritical care burden of aSAH in a middle-income public healthcare system. Despite timely access to definitive aneurysm treatment, patients experienced frequent neurological and systemic complications, emphasizing that contemporary aSAH care extends well beyond aneurysm occlusion.

Temporal and geographical lineage dynamics of invasive Streptococcus pyogenes in Australia from 2011 to 2023: a retrospective, multicentre, clinical and genomic epidemiology study.

BACKGROUND: Defining the temporal dynamics of invasive Streptococcus pyogenes (group A Streptococcus) and differences between hyperendemic and lower-incidence regions provides crucial insights into pathogen evolution and, in turn, informs preventive measures. We aimed to examine the clinical and temporal lineage dynamics of S pyogenes across different disease settings in Australia to improve understanding of drivers of pathogen diversity. METHODS: In this retrospective, multicentre, clinical and genomic epidemiology study, we identified cases of invasive S pyogenes infection from normally sterile sites between Jan 1, 2011, and Feb 28, 2023. Data were collected from five hospital networks across low-incidence regions in temperate southeast Australia and the hyperendemic, tropical, and largely remote Top End of the Northern Territory of Australia. The crude incidence rate ratio (IRR) of bloodstream S pyogenes infection comparing the Top End and southeast Australia and in First Nations people compared with non-First Nations people was estimated by quasi-Poisson regression. We estimated odds ratios (ORs) of intensive care unit (ICU) admission, in-hospital mortality, and 30-day mortality for the Top End versus southeast Australia using logistic regression. Retrieved and successfully sequenced isolates were assigned lineages at whole-genome resolution. Temporal trends in the composition of co-circulating lineages were compared between the two regions. We used an S pyogenes-specific multistrain simulated transmission model to examine the relationship between host population-specific parameters and observed pathogen lineage dynamics. The prevalence of accessory genes (those present in 5-95% of all genomes) was compared across geographies and temporal periods to investigate genomic drivers of diversity. FINDINGS: We identified 500 cases of invasive S pyogenes infection in patients in the Top End and 495 cases in patients in southeast Australia. The crude IRR of bloodstream infection for the Top End compared with southeast Australia was 5·97 (95% CI 4·61-7·73) across the entire study period; in the Top End, infection disproportionately affected First Nations people compared with non-First Nations people (5·41, 4·28-6·89). The odds of in-hospital mortality (OR 0·43, 95% CI 0·26-0·70), 30-day mortality (0·38, 0·23-0·63), and ICU admission (0·42, 0·30-0·59) were lower in the Top End than in southeast Australia. Longitudinal lineage analysis of 642 S pyogenes genomes identified waves of replacement with distinct lineages in the Top End, whereas southeast Australia had a small number of dominant lineages that persisted and cycled in frequency. The transmission model qualitatively reproduced a similar pattern of replacement with distinct lineages when using a high transmission rate, small population size, and high levels of human movement-characteristics similar to those of communities in the hyperendemic Top End. Using a lower transmission rate, larger population size, and lower levels of migration similar to those of communities in urbanised southeast Australia, the transmission model qualitatively reproduced a pattern of dominant lineages that cycled in frequency. Despite distinct circulating lineages, the prevalence of accessory genes in the bacterial population was maintained across geographies and temporal periods. INTERPRETATION: In a hyperendemic setting, the replacement of distinct S pyogenes lineages occurred in waves, which could be linked to the disproportionate burden of disease and sparse human population in this setting. The maintenance of bacterial gene frequency could be consistent with multilocus selection. These findings suggest that lineage-specific interventions-such as vaccines under development-should consider disease setting and, without broad cross-protection, might lead to lineage replacement.

Respiratory syncytial virus (RSV) in older adults: from infection to outcomes - who gets sick, who gets hospitalized, who survives?

Respiratory syncytial virus (RSV) is a virus responsible for acute respiratory infections and is widely recognized as a major pathogen in the paediatric population. Thus, the burden of RSV in the adult population remains poorly understood, as epidemiological studies mainly rely on PMSI (Medicalization of Information Systems Program) data, which are coded for economic purposes, and because many adults RSV infections remain underdiagnosed. The aim of this study was to describe epidemiological and clinical characteristics of RSV infections in elderly population across four university hospitals in north-western France during the 2022-2023 epidemic season. This retrospective cohort included all patients aged 60 years and older who tested positive for RSV between September 1st, 2022, and January 31st, 2023, in four university hospitals. Viral detection was performed using molecular assays on respiratory samples. Clinical, demographic, biological, and coding data were collected from medical records and hospital information systems. Outcomes included need for oxygen therapy, intensive care admission, in-hospital mortality, length of stay, readmission within 90 days for a respiratory or cardiac reason, and changes in living arrangements. Statistical analyses used descriptive methods and standard tests for comparisons. A total of 647 patients were included. The mean age was 77.8 years, and most patients had at least one chronic medical condition, primarily respiratory or cardiac. 508 (78.5%) patients were hospitalized. The mean hospital stay was 16.2 days, and oxygen therapy was required in 68.3% of cases. In-hospital mortality reached 11.0%. Among survivors, 38.0% were readmitted within 90 days for a respiratory or cardiac reason. A notable proportion of patients experienced a loss of autonomy leading to institutional placement at discharge. RSV was coded in the PMSI database as a diagnosis in approximately two-thirds of hospitalizations, with substantial variations between centers. RSV infection in older adults was associated with significant morbidity, prolonged hospitalization, and a frequent decline in functional status. The study also identified heterogeneity in coding practices and emphasized limitations of PMSI data for capturing respiratory syncytial virus burden. These findings support the need for expanded screening, along with targeted preventive strategies and structured post-discharge follow-up to reduce the long-term burden of RSV in older populations.

The association between neighbourhood marginalization and SARS-CoV-2 outcomes in patients presenting to emergency departments.

OBJECTIVE: Social and economic marginalizations have been associated with inferior health outcomes in Canada. Our objective was to describe the relationship between neighbourhood marginalization and COVID-19 outcomes among patients presenting to Canadian emergency departments (ED). METHODS: We conducted an observational study among consecutive COVID-19 patients recruited from 47 hospitals participating in the Canadian COVID-19 ED Rapid Response Network (CCEDRRN) between March 3, 2020, and July 24, 2022. We linked data with the Canadian Marginalization Index (CAN-Marg). We used multivariable, multi-level logistic regression models to understand the association between dimensions of neighbourhood marginalization, and severe COVID-19 and in-hospital mortality. RESULTS: There were 55,588 eligible patients. Those from neighbourhoods with a higher proportion of recent immigrants (OR = 0.86 per unit increase [0.81, 0.92]), lower workforce participation (OR = 0.84 per unit increase [0.75, 0.94]), and more housing insecurity (OR = 0.81 per unit increase [0.77, 0.86]) were less likely to present to EDs with severe COVID-19. However, patients from materially marginalized neighbourhoods had increased odds of dying in hospital (OR = 1.19 per unit increase [95% CI 1.09, 1.30]) compared to patients from less materially marginalized neighbourhoods. Patients living in neighbourhoods with a higher proportion of recent immigrants (OR = 0.83 per unit increase [0.78, 0.91]) and lower participation in the workforce (OR = 0.77 per unit increase [0.66, 0.87]) experienced lower odds of dying. CONCLUSION: Despite no association with severe COVID-19 at ED presentation, the only marginalization domain associated with in-hospital mortality was material deprivation. Our findings present insights on ED-seeking behaviour, hospital access, and care that population studies could not.

Clinical characteristics and outcomes of post-stroke seizures following reperfusion therapy: a retrospective single-center study.

BACKGROUND: Post-stroke seizures (PSS) are a recognized complication of ischemic stroke and may adversely affect functional outcomes and survival; however, their characteristics in patients receiving contemporary reperfusion therapy remain incompletely defined. We aimed to describe the clinical characteristics, treatment patterns, and outcomes of patients who developed PSS following reperfusion therapy and to compare early- and late-onset seizure subgroups. METHODS: This single-center retrospective study included adult patients with acute ischemic stroke treated with intravenous thrombolysis (IV-tPA), mechanical thrombectomy (MT), or combined therapy between January 2020 and September 2025. Early seizures were defined as occurring within 7 days of stroke onset. Clinical, radiological, and treatment-related variables were analyzed, and functional outcome was assessed using the modified Rankin Scale at 3 months. RESULTS: Of 1242 patients who received reperfusion therapy, 53 (4.27 %; 95 % CI 3.28-5.54) developed PSS. Observed seizure rates were 3.39 % in the MT group, 4.06 % in the IV-tPA group, and 7.02 % in the combined therapy group; these observed rates did not differ significantly across treatment modalities. Early seizures occurred in 23 patients and late seizures in 30. No significant differences were found between early- and late-onset seizure subgroups in demographic characteristics, vascular risk factors, stroke severity, reperfusion success, or clinical outcomes, with the exception of an isolated, exploratory difference in stroke laterality. Three-month mortality among patients with PSS was 45.28 % (95 % CI 32.66-58.55), and in-hospital mortality was 20.75 %. CONCLUSIONS: In this single-center cohort, the incidence of PSS after reperfusion therapy was comparable to previously reported rates, with no marked differences across treatment modalities. The high mortality among patients with PSS likely reflects underlying stroke severity rather than a treatment-specific risk.

Coronary-artery bypass surgery in stable angina pectoris: Survival at two years. European Coronary Surgery Study Group.

768 men aged under 65 with angina pectoris, at least 50% obstruction in two or more major vessels, and a left-ventricular ejection fraction greater than or equal to 0.5 took part in a prospective randomised trial of the effect of coronary-artery bypass on prognosis. 373 patients were alloted to medical and 395 to surgical treatment. There was no significant difference between the two groups in the distribution of variables recorded at the time of randomisation. 1. "surgical" patient was lost to follow-up. 26 "surgical" patients did not undergo surgery and 50 "medical" patients were operated on. All these 76 patients were retained in their original treatment groups for the analysis. At 2 years there was no significant difference in mortality between the two groups. A significant difference was, however, found in the subset of patients with three-vessel disease, survival being significantly better for surgical patients. Operative (in-hospital) mortality was 3.6% in all operated patients and 1.5% in the last third. On average, 1.9 grafts per patient were inserted in the two-vessel-disease subgroup and 2.4 grafts per patient in the three-vessel-disease subgroup. Graft-patency rate was 90% within 9 months and 77% between 9 and 18 months after surgery. Symptomatic improvement was significantly better and deterioration less in the surgical group.

Metagenomic next-generation sequencing of cerebrospinal fluid reveals pathogen spectrum and mortality predictors among patients with advanced HIV-1 disease at a tertiary hospital in China.

BACKGROUND: Central nervous system (CNS) infections remain the major causes of morbidity and mortality among people living with HIV-1 (PLWH), particularly in resource-limited settings. However, the clinical characteristics and prognostic indicators of PLWH with suspected CNS infections are not well defined. In this study, we aim to characterize the spectrum of CNS pathogens, clinical characteristics, in-hospital mortality, and factors associated with death among people with advanced HIV-1 disease (AHD) in Guangxi, China. METHODS: Metagenomic next-generation sequencing (mNGS) was performed to analyze types of infection in cerebrospinal fluid (CSF) from 61 treatment-naive PLWH with suspected CNS infections. Clinical data, routine laboratory tests, and biochemical tests were collected and analyzed. RESULTS: Among the 61 CSF samples, primarily with AHD, a total of 206 pathogens were identified. Viral pathogens predominated, with Epstein-Barr virus being the most frequently identified, followed by cytomegalovirus. Compared with patients with single-pathogen infection, those with multiple infections (viral, bacterial, and fungal) exhibited significantly lower CD4 T cell counts, higher C-reactive protein levels, and markedly reduced lipid metabolism parameters. However, infection types were not significantly associated with in-hospital death. Multivariate logistic regression analysis identified plasma low density lipoprotein (LDL) and CSF lactate dehydrogenase (LDH) as independent predictors of in-hospital death. CONCLUSION: In PLWH with AHD and suspected CNS infections, multiple pathogens frequently coexist in the CSF. Plasma LDL and CSF LDH levels were independent predictors of death, indicating their potential value as early risk stratification in AHD.

A 20-Y Analysis of Motorcycle Trauma After Helmet Law Repeal.

INTRODUCTION: After Arkansas repealed its universal motorcycle helmet law in 1997, helmet use decreased and motorcycle-related injuries and fatalities increased. Long-term clinical and population-level impacts of this policy change remain incompletely characterized. This study integrates statewide crash and fatality data with trauma center data to evaluate trends in helmet use, injury severity, and mortality at scene and hospitalization. METHODS: We retrospectively reviewed motorcycle-related admissions and emergency department deaths at the state's only adult level I trauma center from 2004 to 2023 across three periods: 2004-2006, 2013-2015, and 2021-2023. Demographics, helmet use, injury severity, and outcomes were assessed. Logistic regression evaluated associations between helmet use, severe head injury (Abbreviated Injury Scale ≥3), and inhospital mortality. Fatality data were obtained from the National Highway Traffic Safety Administration, and crash-level data (2015-2023) were obtained from the State Department of Transportation. RESULTS: Among 1104 trauma admissions, annual admissions nearly tripled over time, with nonhelmeted riders representing 64%-72%. Helmet use was independently associated with lower odds of severe head injury (odds ratio 0.48, P < 0.001). Nonhelmeted riders had higher on-scene fatality risk (relative risk 1.21). Severe head injuries increased and were strong predictors of inhospital mortality. Population-adjusted motorcycle fatality rates rose from 2.34 to 3.18 per 100,000 residents by 2021-2023. CONCLUSIONS: Motorcycle fatalities and severe head injuries increased during the postrepeal period and were associated with helmet nonuse and severe head trauma. Clinical and statewide data show consistent associations among helmet nonuse, severe head injury, and prehospital and in-hospital mortality, highlighting helmet use as a target for injury prevention policy.

Prospective characterisation of drug-resistant bloodstream infections in Africa and Asia (ACORN2): a surveillance network assessment.

BACKGROUND: Antimicrobial resistance (AMR) is a major global health threat, but there is scarcity of laboratory surveillance data linked to clinical information to determine burden and inform interventions, especially from low-income and middle-income countries. The ACORN2 study sought to address this through prospective case-based surveillance in 19 hospitals across Africa and Asia to characterise drug-resistant infections by origin, clinical syndrome, patient age, outcome, and geographical location. METHODS: Patients were enrolled on selected wards and clinical data were collected daily for community-acquired infections (CAIs). Point prevalence surveys for hospital-acquired infections (HAIs) were conducted weekly. Mortality was assessed at discharge and after 28 days. Linked microbiology data were extracted from local laboratory databases. Primary descriptive analyses focused on WHO Global Antimicrobial Resistance and Use Surveillance System pathogen (target organism) bloodstream infections (BSIs). Comparisons were adjusted for clustering by site using random effects models. FINDINGS: Over 31 months, 41 907 infections were characterised from 41 032 admissions. Two-thirds were children (19 351; 47·2%) or neonates (6649; 16·2%). There were marked differences in pathogen incidence and antibiotic resistance when clinical infections were stratified by patient age category and infection origin (CAI/HAI). The highest rates of target organism AMR BSI were third-generation cephalosporin-resistant (3GC-R) Escherichia coli (718·56/100 000 blood cultured infection episodes), meticillin-resistant Staphylococcus aureus (586·89/100 000 blood cultured infection episodes), and 3GC-R Klebsiella pneumoniae (364·92/100 000 blood cultured infection episodes). In-hospital mortality was 13·1% (166/1265) in patients with target organism BSI versus 6·2% (1357/21 845) in those with negative blood cultures, p<0·0001. INTERPRETATION: ACORN2 has shown practical implementation of collecting linked clinical-laboratory AMR data in low-income and middle-income countries and identified a significant burden of WHO GLASS BSI. Adoption of the ACORN2 approach at scale might enhance use of diagnostic microbiology and improve the volume of clinical data included in national and global AMR surveillance datasets.

Genetic characterization of carbapenem-resistant Klebsiella pneumoniae bloodstream isolates with reduced susceptibility to cefiderocol.

OBJECTIVES: To assess cefiderocol activity against carbapenem-resistant Klebsiella pneumoniae (CRKP) bloodstream isolates collected before local clinical introduction and to characterize the distribution of borderline MIC elevation across major genomic backgrounds. METHODS: We retrospectively analyzed 389 episodes of K. pneumoniae bloodstream infection at a tertiary hospital in China during 2018-2024. All 83 carbapenem-resistant isolates underwent cefiderocol broth microdilution testing and whole-genome sequencing. For epidemiological analysis, reduced susceptibility was prespecified as an MIC of 4-16 mg/L and was not intended to replace clinical breakpoint interpretation. RESULTS: CRKP accounted for 21.3% of K. pneumoniae bloodstream infections and remained associated with in-hospital mortality after adjustment for infection severity and source. By CLSI criteria, 83.1% of isolates were cefiderocol susceptible; the MIC50 and MIC90 were 4 and 8 mg/L, respectively, and 41.0% met the reduced-susceptibility definition. ST11 predominated, with KL47 and KL64 as the main capsular loci. Cefiderocol MICs were higher among KL47/KL64 and virulence-plasmid-associated isolates than among comparator backgrounds. In multivariable analysis, bla NDM-1, bla SHV-12, and the aerobactin locus remained associated with reduced susceptibility, although the findings require cautious interpretation because of limited sample size and possible effects of clonal background. No inactivating mutations were identified in cirA, fepA, or fiu. CONCLUSIONS: Borderline cefiderocol MIC elevation was present before local drug exposure and was more frequent in locally prevalent ST11-KL47/KL64 and virulence-plasmid-associated CRKP. These findings provide a bloodstream-specific pre-introduction baseline and support prospective surveillance of numerical MIC distributions and associated genomic backgrounds.

Pacreaticoduodenectomy.

Pancreaticoduodenectomy, the Whipple operation, is a reasonable operation for carcinoma if used in the absence of distant metastases or regional spread to vital structures. It can be performed with an acceptable in-hospital mortality. It is primarily a palliative surgical procedure. Occasionally, a patient will survive more than five years. At times, the operation is fully justified or cannot be avoided for nonmalignant conditions.

Clinical outcomes and care for spontaneous bacterial peritonitis: A national cohort study.

BACKGROUND AND AIMS: Spontaneous bacterial peritonitis (SBP) leads to high rates of acute kidney injury (AKI), hepatorenal syndrome, and mortality. Population-based studies on contemporary SBP epidemiology are needed to inform care. In a large, national cohort of patients diagnosed with SBP and confirmed by ascitic fluid criteria, we characterized ascitic fluid characteristics, in-hospital and 12-month mortality, AKI, and recurrent SBP. APPROACH AND RESULTS: We investigated how individual and bundled quality measures for SBP associated with outcomes after multi-level adjustment for health-system, patient clinical factors, and quality measures. Individual and bundled quality metrics were inpatient antibiotics within 48 hours, i.v. albumin, repeat paracentesis within 48 hours, recognition of SBP, and prophylactic antibiotics upon discharge. Among 4330 patients with newly diagnosed SBP, in-hospital mortality was 15.5%, and 12-month mortality was 56.6%. The incidence of stage 1 AKI was 26.6%, 15.7% for stage 2, and 22.8% for stage 3. The cumulative incidence of recurrent SBP was 10.3%. Guideline-recommended albumin was the only individual metric associated with reduced in-hospital mortality (HR: 0.73, 95% CI: 0.59-0.91). Receipt of a higher number of metrics from the SBP bundle was associated with progressively lower 12-month post-discharge mortality: patients who received 3, 4, and 5 SBP bundle components had 20%, 38%, and 56% lower hazard of mortality, respectively, relative to those receiving 2 or fewer (all p <0.001). The SBP bundle was associated with a lower incidence of stage 3 versus stage 0-2 AKI (OR: 0.66, 95% CI: 0.51-0.86). CONCLUSIONS: Prospective implementation of evidence-based SBP bundles may improve care outcomes and mortality in SBP.

Higher versus Routine Intraoperative Blood Pressure Targets in Noncardiac Surgery: A Systematic Review and Meta-analysis with Trial Sequential Analysis of Randomized Trials.

BACKGROUND: Observational studies consistently link intraoperative hypotension to adverse postoperative outcomes, leading guidelines to recommend maintaining mean arterial pressure 60 to 65 mmHg or greater during noncardiac surgery. Whether targeting higher intraoperative blood pressure values improves clinical outcomes remains uncertain. METHODS: The authors conducted a Preferred Reporting Items for Systematic Reviews and Meta-analyses-guided search on PubMed, Cochrane Central Register of Controlled Trials, Scopus, and Embase from inception to April 2026. Randomized trials comparing higher intraoperative blood pressure targets, either as fixed absolute thresholds or personalized to preoperative baseline, versus routine blood pressure management in adults undergoing elective noncardiac surgery with general anesthesia were included. Outcomes included in-hospital or 30-day mortality, postoperative delirium, acute kidney injury (AKI), 30-day major cardiovascular events, acute myocardial injury, stroke, length of stay, and intraoperative hypotension. RESULTS: Fifteen trials (15,603 patients) were included. Higher targets did not reduce AKI (risk ratio [RR], 0.95; 95% CI, 0.85 to 1.06; P = 0.36; I 2 = 16%) or acute myocardial injury (RR, 1.02; 95% CI, 0.94 to 1.12; P = 0.59; I 2 = 0%) compared with routine targets, with firm evidence from trial sequential analysis. Higher targets were associated with a significant reduction in postoperative delirium (RR, 0.73; 95% CI, 0.54 to 0.98; P = 0.04; I 2 = 26%), although trial sequential analysis indicated the cumulative evidence remained insufficient to draw firm conclusions. No significant effect was observed on in-hospital or 30-day mortality (RR, 1.00; 95% CI, 0.75 to 1.34; P = 1.00; I 2 = 0%); evidence on 30-day major cardiovascular events, stroke, and length of stay was similarly insufficient to draw firm conclusions. CONCLUSION: In adults undergoing elective noncardiac surgery, targeting higher intraoperative blood pressure values does not improve major postoperative outcomes compared with routine management. A potential reduction in postoperative delirium warrants confirmation in adequately powered trials.

Long-term mortality in pediatric sepsis: a systematic review and meta-analysis.

BACKGROUND: Pediatric sepsis represents a significant factor in the mortality rates among children, with survivors remaining highly fragile during the period following discharge. While in-hospital and short-term mortality have been widely studied, the long-term mortality of pediatric sepsis is not adequately synthesized or appreciated. This study aims to estimate the long-term mortality associated with pediatric sepsis, providing a basis for optimizing post-discharge surveillance and care protocols. METHODS: This systematic review and meta-analysis followed PRISMA guidelines and was registered in PROSPERO (CRD420251137504). Exhaustive searches were conducted in PubMed, Embase, the Cochrane Library, and Web of Science for studies published from the inception of each database to June 30, 2025. Studies reporting long-term mortality in pediatric sepsis patients diagnosed using international consensus criteria were included. After literature screening, long-term mortality was pooled using a random effects meta-analysis in R statistical software. RESULTS: A total of 72,065 records were identified through database searching. After removing duplicates and screening, six studies comprising 11,318 pediatric sepsis patients were included. The pooled long-term mortality in pediatric sepsis was 11% (95% CI: 7-16%), though significant heterogeneity was observed (I2 = 98.2%, p < 0.001). Sensitivity analyses yielded similar results, and evidence of publication bias was limited. CONCLUSION: Long-term mortality after pediatric sepsis was 11%, highlighting the persistent risk of mortality after hospital discharge. Further high-quality longitudinal studies are required to identify modifiable risk factors and guide evidence-based follow-up and personalized care.

Efficacy and Safety of Autologous Versus Prosthetic Grafts in the Repair of Popliteal Artery Aneurysms: A Systematic Review and Meta-Analysis.

BACKGROUND: Popliteal artery aneurysms (PAAs) present a severe risk of progression to acute limb ischemia. Open surgery (OS) is the gold standard treatment; however, prosthetic grafts are acceptable in highly selected cases, especially when the great saphenous vein is not available. METHODS: We performed a systematic review and meta-analysis of studies comparing autologous versus prosthetic grafts for patency and limb preservation outcomes in patients with PAAs. MEDLINE, Embase, and Cochrane Central were systematically searched from inception through October 2024. Outcomes were pooled using a frequentist random-effects model as odds ratios, mean differences, and hazard ratios (HRs) with 95% confidence intervals (CIs) on RStudio (Version 4.5.0). Risk-of-bias assessments were performed using ROBINS-I and MINORS. RESULTS: Twenty-two observational studies were pooled comprising 9,145 PAAs in 8,370 patients, of whom 6,434 (74.51%) were treated with autologous grafts and 2,200 (25.49%) with prosthetic grafts. Follow-up ranged from 12 to 86 months. Repair with autologous conduits significantly improved long-term primary patency (HR 3.93; P < 0.001), secondary patency (HR 6.02; P < 0.001), and long-term limb salvage (HR 2.69; P = 0.044) compared with prosthetic conduits. There were no significant differences in in-hospital amputation (P = 0.36), myocardial infarction (P = 0.61), mortality (P = 0.50), 2-year primary patency (P = 0.25), 5-year secondary patency (P = 0.06), or length of hospital stay (P = 0.95). Risk of bias was classified as moderate-to-high, reflecting confounding factors inherent to observational studies and moderate methodological quality by MINORS. Despite these limitations, treatment effects consistently favored autologous grafts in both short- and long-term analyses; however, caution is warranted given the limited number of available studies. CONCLUSION: The use of autologous conduits significantly favors both short-term and long-term efficacy and safety in the OS repair of PAAs. Given the limitations of the existing evidence, further comparative studies are needed.

Rotavirus vaccine effectiveness against rotavirus and acute gastroenteritis mortality: an analysis of pooled case-control studies from the MNSSTER-V dataset.

BACKGROUND: Rotavirus accounts for an estimated 25% of diarrhoea deaths in children under 5 years globally, and more than 140 countries have included rotavirus vaccines in their routine national infant vaccination programmes. We aimed to calculate rotavirus vaccine effectiveness against rotavirus-positive and all-cause acute gastroenteritis deaths. METHODS: The Multi-National Subpopulations Study to Evaluate Rotavirus Vaccines (MNSSTER-V) dataset combines child-level data from test-negative case-control studies of rotavirus vaccine effectiveness that enrolled children under 5 years of age seeking care for acute gastroenteritis at hospitals or emergency departments in 24 countries between July 1, 2007, and Aug 24, 2023. Children were included in this study if they were: younger than 5 years, met the acute gastroenteritis case definition (had at least three episodes of diarrhoea in a 24-h period, had non-bloody and non-chronic diarrhoea, and were enrolled within 7 days of diarrhoea onset), met vaccine card quality metrics, had vaccine delivery dates if the child was reported to have received a rotavirus vaccine, and had a reported outcome of death or discharge. In-hospital acute gastroenteritis deaths were characterised, and rotavirus vaccine effectiveness against all-cause and rotavirus-positive acute gastroenteritis mortality was calculated using an unconditional logistic regression model with adjustment for national under-5 mortality strata and child's age. Vaccine effectiveness analyses against all-cause and rotavirus-positive acute gastroenteritis mortality were restricted to children aged at least 3 months who received any routine vaccines from countries reporting at least one acute gastroenteritis death. FINDINGS: From the MNSSTER-V dataset, we included 27 252 children younger than 5 years enrolled from 22 countries; outcomes of patients were not available for two countries. At least one in-hospital acute gastroenteritis death was reported from 16 countries including 21 522 children; in total, 183 all-cause acute gastroenteritis deaths and 25 rotavirus-positive deaths were reported. Among children aged at least 3 months who had received any routine vaccines, receiving at least one dose of a rotavirus vaccine had an adjusted vaccine effectiveness of 75·8% (95% CI 28·4 to 91·8; n=13 630) against rotavirus-positive acute gastroenteritis mortality and 20·8% (-47·0 to 57·3; n=20 005) against all-cause acute gastroenteritis mortality. INTERPRETATION: Rotavirus vaccines are effective in preventing rotavirus-positive acute gastroenteritis mortality. Continued efforts to improve vaccine delivery could help to reduce acute gastroenteritis mortality due to rotavirus worldwide. FUNDING: None.
