Importance Racial and ethnic disparities exist in urogynecologic surgery; however, literature identifying specific disparities after sling operations for stress incontinence are limited. Objective The objective of this study was to evaluate racial and ethnic disparities in surgical complications within 30 days of midurethral sling operations. Study Design This retrospective cohort study identified women who underwent an isolated midurethral sling operation between 2014 and 2021 using the American College of Surgeons National Surgical Quality Improvement Program database. Women were stratified by racial and ethnic category to assess the primary outcome, 30-day surgical complications, and the secondary outcome, comparison of urinary tract infections (UTIs). Results There were 20,066 patients included. Mean age and body mass index were 53.9 years and 30.8, respectively. More Black or African American women had diabetes and hypertension, and more American Indian or Alaska Native women used tobacco. The only difference in 30-day complications was stroke/cerebrovascular accident, which occurred in only 1 Asian, Native Hawaiian or other Pacific Islander patient (0.1%, P < 0.0001). The most frequent complication was UTI (3.3%). Black or African American women were significantly less likely to have a diagnosis of UTI than non-Hispanic White (P = 0.04), Hispanic White (P = 0.03), and American Indian or Alaska Native women (P = 0.04). Conclusions Surgical complications within 30 days of sling operations are rare. No clinically significant racial and ethnic differences in serious complications were observed. Urinary tract infection diagnoses were lower among Black or African American women than in non-Hispanic White, Hispanic White, and American Indian or Alaska Native women despite a greater comorbidity burden. No known biologic reason exists to explain lower UTI rates in this population; therefore, this finding may represent a disparity in diagnosis and treatment.

ImportanceEndovascular thrombectomy (EVT) is standard treatment for acute ischemic stroke (AIS) due to large-vessel occlusion (LVO), but optimal post-EVT blood pressure (BP) control remains debated.ObjectiveTo assess the association of different systolic BP targets following EVT with functional outcomes, mortality, and complications in patients with AIS due to LVO.Data SourcesSystematic review and meta-analysis of databases (PubMed, Embase, Web of Science, Scopus, and Cochrane Library) to September 8, 2023.Study SelectionInclusion criteria consisted of randomized clinical trials examining post-EVT management of systolic BP in patients with AIS and LVO comparing intensive vs conventional targets. Nonrandomized studies, observational studies, noninterventional trials, meeting abstracts, duplicate studies, studies with overlapping data, and non–English language studies were excluded. Two authors independently applied these criteria through a blinded review, with discrepancies resolved through consensus. The risk of bias in the included studies was assessed using the revised tool for assessing risk of bias in randomized trials.Data Extraction and SynthesisThis study adhered to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) reporting guideline. Three authors extracted data regarding study characteristics, baseline patient data, and outcomes of interest. The pooled data were analyzed using a random-effects meta-analysis.Main Outcomes and MeasuresRates of functional independence, 90-day mortality, symptomatic intracranial hemorrhage, and hypotensive events.ResultsA total of 4 randomized clinical trials with 1571 initially enrolled patients were included in the analysis. Lower functional independence rates were observed in the intensive control group (relative risk [RR], 0.81 [95% CI, 0.67-0.98]). No significant differences were found in 90-day mortality (RR, 1.18 [95% CI, 0.92-1.52]), symptomatic intracranial hemorrhage (RR, 1.12 [95% CI, 0.75-1.67]), or hypotensive events (RR, 1.80 [95% CI, 0.37-8.76]). There was minimal heterogeneity among the studies included in the functional independence outcome (I2 = 13% and τ2 = 0.003), which was absent among other outcomes (I2 = 0 and τ2 = 0).Conclusions and RelevanceThese findings suggest that intensive post-EVT BP reduction does not yield benefits and may carry risks. While awaiting the results of additional ongoing trials, a conservative BP management strategy after endovascular recanalization is favored in daily practice.

BACKGROUND: Venous thromboembolism occurs in approximately 2% of patients undergoing abdominal and pelvic surgery for cancers of the colon, rectum, and anus and is considered preventable. The American Society of Colon and Rectal Surgeons recommends extended prophylaxis in high-risk patients, but there is low adherence to the guidelines. OBJECTIVE: This study aims to analyze the impact of venous thromboembolism risk-guided prophylaxis in patients undergoing elective abdominal and pelvic surgeries for colorectal and anal cancers from 2016 to 2021. DESIGN: This was a retrospective analysis. SETTING: The study was conducted at a multisite tertiary referral academic health care system. PATIENTS: Patients who underwent elective abdominal or pelvic surgery for colon, rectal, or anal cancer. MAIN OUTCOME MEASURES: Receipt of Caprini-guided venous thromboembolism prophylaxis, 90-day postoperative rate of deep vein thrombosis, pulmonary embolism, venous thromboembolism, and bleeding events. RESULTS: A total of 3504 patients underwent elective operations, of whom 2224 (63%) received appropriate thromboprophylaxis in the inpatient setting. In the postdischarged cohort of 2769 patients, only 2% received appropriate thromboprophylaxis and no thromboembolic events were observed. In the group receiving inappropriate thromboprophylaxis, at 90 days postdischarge, the deep vein thrombosis, pulmonary embolism, and venous thromboembolism rates were 0.60%, 0.40%, and 0.88%, respectively. Postoperative bleeding was not different between the 2 groups. LIMITATIONS: Limitations to our study include its retrospective nature, use of aggregated electronic medical records, and single health care system experience. CONCLUSION: Most patients in our health care system undergoing abdominal or pelvic surgery for cancers of the colon, rectum, and anus were discharged without appropriate Caprini-guided venous thromboembolism prophylaxis. Risk-guided prophylaxis was associated with decreased rates of inhospital and postdischarge venous thromboembolism without increased bleeding complications. See Video Abstract. MARGEN DE MEJORA: EL IMPACTO DE LA TROMBOPROFILAXIS RECOMENDADA POR LAS DIRECTRICES EN PACIENTES SOMETIDOS A CIRUGÍA ABDOMINAL POR CÁNCER COLORRECTAL Y ANAL EN UN CENTRO DE REFERENCIA TERCIARIO ANTECEDENTES: El tromboembolismo venoso ocurre en aproximadamente el 2% de los pacientes sometidos a cirugía abdominal y pélvica por cánceres de colon, recto y ano, y se considera prevenible. La Sociedad Estadounidense de Cirujanos de Colon y Recto recomienda una profilaxis prolongada en pacientes de alto riesgo, pero el cumplimiento de las directrices es bajo. OBJETIVO: Este estudio tiene como objetivo analizar el impacto de la profilaxis guiada por el riesgo de tromboembolismo venoso (TEV) en pacientes sometidos a cirugías abdominales y pélvicas electivas por cáncer colorrectal y anal entre 2016 y 2021. DISEÑO: Este fue un análisis retrospectivo. AJUSTE: El estudio se llevó a cabo en un sistema de salud académico de referencia terciaria de múltiples sitios. PACIENTES: Pacientes sometidos a cirugía abdominal o pélvica electiva por cáncer de colon, recto o ano. PRINCIPALES MEDIDAS DE RESULTADO: Recepción de profilaxis de tromboembolismo venoso guiada por Caprini, tasa postoperatoria de 90 días de trombosis venosa profunda, embolia pulmonar, tromboembolismo venoso y eventos de sangrado. RESULTADOS: Un total de 3.504 pacientes se sometieron a operaciones electivas, de los cuales 2.224 (63%) recibieron tromboprofilaxis adecuada en el ámbito hospitalario. En el cohorte de 2.769 pacientes después del alta, solo el 2% recibió tromboprofilaxis adecuada en la que no se observaron eventos tromboembólicos. En el grupo que recibió tromboprofilaxis inadecuada, a los 90 días después del alta, las tasas de trombosis venosa profunda, embolia pulmonar y tromboembolia venosa fueron del 0,60%, 0,40% y 0,88%, respectivamente. El sangrado posoperatorio no fue diferente entre los dos grupos. LIMITACIONES: Las limitaciones de nuestro estudio incluyen su naturaleza retrospectiva, el uso de registros médicos electrónicos agregados y la experiencia de un solo sistema de atención médica. CONCLUSIÓN: La mayoría de los pacientes en nuestro sistema de salud sometidos a cirugía abdominal o pélvica por cánceres de colon, recto y ano fueron dados de alta sin una profilaxis adecuada de TEV guiada por Caprini. La profilaxis guiada por el riesgo se asoció con menores tasas de tromboembolismo venoso hospitalario y dado de alta sin un aumento de las complicaciones de sangrado.

AbstractINTRODUCTIONThis study examined lucid episodes among people living with late‐stage Alzheimer's disease and related dementias (PLWD) and then developed a typology of these episodes to help characterize them.METHODSFamily caregivers of PLWD provided information about witnessed episodes, including proximity to death, cognitive status, duration, communication quality, and circumstances prior to lucid episodes on up to two episodes (caregiver N = 151; episode N = 279). Latent class analysis was used to classify and characterize empirically distinct clusters of lucid episodes.RESULTSFour lucid episode types were identified. The most common type occurred during visits with family and among PLWD who lived > 6 months after the episode. The least common type coincided with family visits and occurred within 7 days of the PLWD's death.DISCUSSIONFindings suggest that multiple types of lucid episodes exist; not all signal impending death; and some, but not all, are precipitated by external stimuli.

The Deterioration Index (DI) is an automatic early warning system that utilizes a machine learning algorithm integrated into the electronic health record and was implemented to improve risk stratification of inpatients. Our pilot implementation showed superior diagnostic accuracy than standard care. A score >60 had a specificity of 88.5% and a sensitivity of 59.8% (PPV 0.1758, NPP 0.9817). However, acceptance in the clinical workflow was divided; nurses preferred standard care, while providers found it helpful.

Background The Woven Endo-Bridge (WEB) device revolutionized the treatment of wide-necked bifurcation aneurysms by intrasaccular flow diversion. The latest advancement is the WEB-17 system, offering greater flexibility with fewer wires, enabling treatment of smaller distal aneurysms using smaller microcatheters than the WEB-21 system. Methods We conducted a systematic review following preferred reporting items for systematic reviews and meta-analyses guidelines, analyzing data from seven retrospective cohort studies involving 483 aneurysms treated with the WEB-17 device. Statistical analysis computed pooled prevalence rates and 95% confidence intervals using appropriate models for each outcome and R software version 4.3.1 (R Foundation for Statistical Computing, Vienna, Austria). Results Technical success was achieved in 475 out of 483 aneurysms treated with the WEB-17 device, with a success rate of 98.34% (95% confidence interval (CI) = 96.72–99.17). Among the successful cases, 4.97% (95% CI = 1.60–14.39) required adjunctive devices. Adequate occlusion, defined as complete occlusion or neck remnants, was observed in 94.41% (95% CI = 88.17–97.46) of cases. Periprocedural complications were infrequent, with thromboembolic complications occurring in 4.93% (95% CI = 3.29–7.30) of cases, hemorrhagic complications in 1.28% (95% CI = 0.58–2.83), and postprocedural neurologic complications in 0.99% (95% CI = 0.31–3.14). Procedure-related morbidity was observed in 1.71% (95% CI = 0.86–3.39) of cases, and there was one procedure-related mortality reported at 0.21% (95% CI = .03–1.50). Mortality unrelated to the procedure occurred in 1% (95% CI = 0.23–4.15). Conclusion Our findings suggest that the WEB-17 device is associated with a high rate of technical success, favorable angiographic outcomes, and a low rate of periprocedural complications. Further research, including prospective trials, is needed to confirm these findings and establish its safety and efficacy definitively.

Background: CO2 Laser (CO2L) technology deployable through flexible endoscopes now allows for their use throughout the airway, although published data are limited. Methods: Retrospective analysis of CO2L bronchoscopic procedures, excluding glottic and subglottic interventions. Procedural success was defined as >50% visual reduction in airway obstruction in the area treated or resolution of the procedural indication. Results: Seventy-two procedures were performed on 36 patients. Nonmalignant indications comprised 66%: stent-associated granulation tissue (28%), granulomatosis with polyangiitis lesions (23%), and lung transplant-related granulation tissue (16%) were the most common. Bronchoscopic access was flexible only in 81% and primarily rigid (combined with flexible) in 18%. The site of intervention was the trachea at 19%, the mainstem at 56%, and lobar/segmental airways at 45%. Procedural success was 89%. CO2L was used exclusively in 19%; in 81%, additional techniques were required, most commonly balloon dilation (59%), cryo-debulking (23%), and rigid dilation (16%). Malignant indications had a nonsignificant trend toward requiring adjuvant techniques (P=0.05). Seventy-six percent of the patients required more than 1 procedure. CO2L exclusive cases had no statistically different needs for subsequent therapeutic bronchoscopies (P=0.10) or time to reintervention (109 vs. 41 days, P=0.07), and reintervention-free survival was similar (P=0.10) and difficult to predict. The complication rate attributable to CO2L was 2.7%. Conclusion: CO2L is a safe and useful tool when precise cutting and vaporization are desired. Its use in multi-modality approaches has high levels of success in adequately selected lesions, adding an ablative potential to dilation techniques. Vasculitis-associated scars/webs and granulation tissue (including stent-associated) appear to be ideal targets.

Background: Posthepatectomy liver failure (PHLF) represents a life-threatening complication with limited therapeutic options. Neutrophils play a critical and dynamic role during regeneratory processes, but their role in human liver regeneration is incompletely understood, especially as underlying liver disease, detectable in the majority of patients, critically affects hepatic regeneration. Here we explored intrahepatic neutrophil accumulation and neutrophil extracellular traps (NETs) in patients with PHLF and validated the functional relevance of NETs in a murine partial hepatectomy (PHx) model. Methods: We investigated the influx of neutrophils, macrophages, eosinophils, and mast cells and the presence of their respective extracellular traps in liver biopsies of 35 patients undergoing hepatectomy (10 patients with PHLF) before and after the initiation of liver regeneration by fluorescence microscopy. In addition, NET formation and neutrophil activation were confirmed by plasma analysis of 99 patients (24 patients with PHLF) before and up to 5 days after surgery. Furthermore, we inhibited NETs via DNase I in a murine PHx model of mice with metabolically induced liver disease. Results: We detected rapid intrahepatic neutrophil accumulation, elevated levels of myeloperoxidase release, and NET formation in regenerating human livers, with a significantly higher increase of infiltrating neutrophils and NETs in patients with PHLF. Circulating markers of neutrophil activation, including elastase, myeloperoxidase, and citrullinated histone H3, correlated with markers of liver injury. In a murine PHx model, we showed that the inhibition of NET accelerated hepatocyte proliferation and liver regeneration. Conclusions: Patients with PHLF showed accelerated intrahepatic neutrophil infiltration and NET formation, which were associated with liver damage. Further, we identified postsurgical myeloperoxidase levels as predictive markers for adverse outcomes and observed that blocking NETs in a murine PHx model accelerated tissue regeneration.
