RESUMEN

BACKGROUND & AIMS: Endoscopic mucosal resection (EMR) is standard therapy for nonpedunculated colorectal polyps ≥20 mm. It has been suggested recently that polyp resection without current (cold resection) may be superior to the standard technique using cutting/coagulation current (hot resection) by reducing adverse events (AEs), but evidence from a randomized trial is missing. METHODS: In this randomized controlled multicentric trial involving 19 centers, nonpedunculated colorectal polyps ≥20 mm were randomly assigned to cold or hot EMR. The primary outcome was major AE (eg, perforation or postendoscopic bleeding). Among secondary outcomes, major AE subcategories, postpolypectomy syndrome, and residual adenoma were most relevant. RESULTS: Between 2021 and 2023, there were 396 polyps in 363 patients (48.2% were female) enrolled for the intention-to-treat analysis. Major AEs occurred in 1.0% of the cold group and in 7.9% of the hot group (P = .001; odds ratio [OR], 0.12; 95% CI, 0.03-0.54). Rates for perforation and postendoscopic bleeding were significantly lower in the cold group, with 0% vs 3.9% (P = .007) and 1.0% vs 4.4% (P = .040). Postpolypectomy syndrome occurred with similar frequency (3.1% vs 4.4%; P = .490). After cold resection, residual adenoma was found more frequently, with 23.7% vs 13.8% (P = .020; OR, 1.94; 95% CI, 1.12-3.38). In multivariable analysis, lesion diameter of ≥4 cm was an independent predictor both for major AEs (OR, 3.37) and residual adenoma (OR, 2.47) and high-grade dysplasia/cancer for residual adenoma (OR, 2.92). CONCLUSIONS: Cold resection of large, nonpedunculated colorectal polyps appears to be considerably safer than hot EMR; however, at the cost of a higher residual adenoma rate. Further studies have to confirm to what extent polyp size and histology can determine an individualized approach.

RESUMEN

The goal of radiation therapy for cancer is to deliver prescribed radiation dose to the tumor while minimizing dose to the surrounding healthy tissues. To evaluate treatment plans, the dose distribution to healthy organs is commonly summarized as dose-volume histograms (DVHs). Normal tissue complication probability (NTCP) modeling has centered around making patient-level risk predictions with features extracted from the DVHs, but few have considered adapting a causal framework to evaluate the safety of alternative treatment plans. We propose causal estimands for NTCP based on deterministic and stochastic interventions, as well as propose estimators based on marginal structural models that impose bivariable monotonicity between dose, volume, and toxicity risk. The properties of these estimators are studied through simulations, and their use is illustrated in the context of radiotherapy treatment of anal canal cancer patients.

RESUMEN

As the mankind counters the ongoing COVID-19 pandemic by the novel severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), it simultaneously witnesses the emergence of mpox virus (MPXV) that signals at global spread and could potentially lead to another pandemic. Although MPXV has existed for more than 50 years now with most of the human cases being reported from the endemic West and Central African regions, the disease is recently being reported in non-endemic regions too that affect more than 50 countries. Controlling the spread of MPXV is important due to its potential danger of a global spread, causing severe morbidity and mortality. The article highlights the transmission dynamics, zoonosis potential, complication and mitigation strategies for MPXV infection, and concludes with suggested 'one health' approach for better management, control and prevention. Bibliometric analyses of the data extend the understanding and provide leads on the research trends, the global spread, and the need to revamp the critical research and healthcare interventions. Globally published mpox-related literature does not align well with endemic areas/regions of occurrence which should ideally have been the scenario. Such demographic and geographic gaps between the location of the research work and the endemic epicentres of the disease need to be bridged for greater and effective translation of the research outputs to pubic healthcare systems, it is suggested.

RESUMEN

Long-term hyperglycemia in individuals with type 2 diabetes (T2D) can detrimentally impact pulmonary function and muscle oxygenation. As a result, these factors can impede the body's adaptation to physical exertion. We aimed to evaluate the oxygen pathway during maximal exercise among overweight/obese individuals with type 2 diabetes free from complications, in comparison with a group of matched overweight/obese individuals without diabetes, specifically concentrating on the effects on pulmonary function and muscle oxygenation. Fifteen overweight/obese adults with type 2 diabetes [glycated hemoglobin (HbA1c) = 8.3 ± 1.2%] and 15 matched overweight/obese adults without diabetes underwent pre- and post exercise lung function assessment. A maximal incremental exercise test was conducted, monitoring muscle oxygenation using near-infrared spectroscopy and collecting arterial blood gas samples. Both groups exhibited normal lung volumes at rest and after exercise. Spirometric lung function did not significantly differ pre- and post exercise in either group. During maximal exercise, the type 2 diabetes group showed significantly lower augmentation in total hemoglobin and deoxygenated hemoglobin compared with the control group. Despite comparable usual physical activity levels and comparable heart rates at exhaustion, the type 2 diabetes group had a lower peak oxygen consumption than controls. No significant differences were found in arterial blood gas analyses ([Formula: see text], [Formula: see text], [Formula: see text], and [Formula: see text]) between the groups. Individuals with type 2 diabetes free from complications displayed normal pulmonary function at rest and post exercise. However, impaired skeletal muscle oxygenation during exercise, resulting from reduced limb blood volume and altered muscle deoxygenation, may contribute to the lower V̇o2peak observed in this population.NEW & NOTEWORTHY Individuals with type 2 diabetes free from micro- and macrovascular complications have normal resting pulmonary function, but their V̇o2peak is impaired due to poor skeletal muscle oxygenation during exercise. Tailoring exercise regimes for this population should prioritize interventions aimed at enhancing muscle oxygenation and blood flow improvement.

RESUMEN

BACKGROUND AND AIMS: Limited evidence exists regarding the impact of glucagon-like peptide-1 receptor agonists (GLP-1RAs) on upper endoscopy. Therefore, a meta-analysis was conducted to comprehensively review the available evidence on this subject. METHODS: A systematic bibliographic search was carried out until May 2024. Pooled estimates were analyzed using a random-effects model, with results presented as odds ratio (OR) and 95% confidence interval (CI). The primary outcome assessed was the rate of retained gastric content (RGC), while secondary outcomes included rates of aborted and repeated procedures, adverse event rate, and rates of aspiration. RESULTS: This analysis included 13 studies involving a total of 84,065 patients. Patients receiving GLP-1RA therapy exhibited significantly higher rates of RGC (OR, 5.56; 95% CI, 3.35 to 9.23), a trend that was consistent among patients with diabetes (OR, 2.60; 95% CI, 2.23 to 3.02). Adjusted analysis, accounting for variables such as sex, age, body mass index, diabetes, and other therapies, confirmed the elevated rates of RGC in the GLP-1RA user group (adjusted OR, 4.20; 95% CI, 3.42 to 5.15). Furthermore, rates of aborted and repeated procedures were higher in the GLP-1RA user group (OR, 5.13; 95% CI, 3.01 to 8.75; and OR, 2.19; 95% CI, 1.43 to 3.35; respectively). However, no significant differences were found in AE and aspiration rates between the 2 groups (OR, 4.04; 95% CI, 0.63 to 26.03; and OR, 1.75; 95% CI, 0.64 to 4.77; respectively). CONCLUSION: Use of GLP-1RAs is associated with increased retention of gastric contents and more frequent aborted procedures during upper endoscopy. However, the adverse event and aspiration rates do not seem different; therefore, adjusting fasting time instead of routinely withholding GLP-1RAs could be reasonable in these patients.

RESUMEN

Long non-coding RNAs are cellular transcripts that have ˃200 nucleotides in length and do not code for proteins. Due to their low expression levels, long non-coding RNAs were previously considered as mere transcriptional noise. However, current evidence indicates that they regulate a myriad of biological processes such as cell proliferation, invasion, and apoptosis. Hence, their expression patterns are crucial indicators of the physiological or pathological states of cells, tissues, and organs. The utilization of long non-coding RNAs as biomarkers and therapeutic targets for the clinical management of several diseases have been suggested. Gradually, long non-coding RNAs are gaining a substantial attention in the field of feto-maternal medicine. After embryo implantation, the interactions between the trophoblast cells from the embryo and the uterus of the mother facilitate placenta development and pregnancy progression. These processes are tightly regulated, and their impairments result in pregnancy pathologies such as miscarriage and preeclampsia. Accumulating evidence implicates long non-coding RNAs in these processes. Herein, we have summarized the roles of several long non-coding RNAs in human placenta development, have proposed some mechanisms by which they participate in physiological and pathological placentation, have revealed some knowledge deficits, and have recommended ideal experimental approaches that will facilitate the clarification of the mechanistic actions of each long non-coding RNA at the feto-maternal interface during healthy and pathological pregnancies.

RESUMEN

Propionic acidemia (PA), arising from PCCA or PCCB variants, manifests as life-threatening cardiomyopathy and arrhythmias, with unclear pathophysiology. In this work, propionyl-CoA metabolism in rodent hearts and human pluripotent stem cell-derived cardiomyocytes was investigated with stable isotope tracing analysis. Surprisingly, gut microbiome-derived propionate rather than the propiogenic amino acids (valine, isoleucine, threonine, and methionine) or odd-chain fatty acids was found to be the primary cardiac propionyl-CoA source. In a Pcca-/-(A138T) mouse model and PA patients, accumulated propionyl-CoA and diminished acyl-CoA synthetase short-chain family member 3 impede hepatic propionate disposal, elevating circulating propionate. Prolonged propionate exposure induced significant oxidative stress in PCCA knockdown HL-1 cells and the hearts of Pcca-/-(A138T) mice. Additionally, Pcca-/-(A138T) mice exhibited mild diastolic dysfunction after the propionate challenge. These findings suggest that elevated circulating propionate may cause oxidative damage and functional impairment in the hearts of patients with PA.

RESUMEN

Liver cirrhosis remains a major health concern globally, but its epidemiology and etiology evolve with time. However, the changing pattern in etiology and cause of liver-related mortality for patients with cirrhosis are not fully elucidated. Herein, our aim was to characterize the temporal trend of the etiological spectrum and evaluate the impact of etiology on liver-related death among patients with compensated cirrhosis (CC) in Beijing, China. Clinical profiles of patients with CC discharged between January 2008 and December 2015 were retrieved from the Beijing hospital discharge database. The mortalities of different etiologies of cirrhosis were calculated. The risks of readmission and liver-related death associated with etiologies were evaluated by the Cox regression model. A total of 23 978 cirrhotic patients were included. The predominant cause was hepatitis B virus (HBV) (58.93%), followed by alcohol (21.35%), autoimmune (14.85%), miscellaneous etiologies (3.55%), and hepatitis C virus (HCV) (1.32%). From 2008 to 2015, the proportion of HBV-related cirrhosis decreased to 28.11%. Meanwhile, the proportions of autoimmune- and miscellaneous-related cirrhosis increased to 28.54% and 13.11%. The risk of liver-related death ranked the highest in patients with miscellaneous cirrhosis, followed by HBV-related cirrhosis, alcohol-related cirrhosis, autoimmune-related cirrhosis, and HCV-related cirrhosis. The 5-year rates of liver-related death were 22.56%, 18.99%, 18.77%, 16.01%, and 10.76%, respectively. HBV-related cirrhosis caused the highest risk of hepatocellular carcinoma (HCC)-related death, whereas alcohol- and miscellaneous-related cirrhosis caused higher risks of decompensation (DC)-related death than HBV-related cirrhosis, with hazard ratios of 1.35 (95% confidence interval [CI]: 1.24-1.48) and 1.20 (95% CI: 1.03-1.40), respectively. HBV remained a common cause of liver cirrhosis but gradually decreased. Mortality disparities existed in etiologies, with higher risks of HCC-related death in HBV-related cirrhosis, and DC-related death in alcohol- and miscellaneous-related cirrhosis.

RESUMEN

OBJECTIVES: To assess the frequency and characteristics of severe relapse in patients with giant cell arteritis (GCA) in a real-life setting. METHODS: In a monocentric database of 530 patients, we retrospectively analysed patients who experienced at least one relapse and distinguished severe from nonsevere relapses. Severe relapse was defined by the occurrence of an ischaemic event (ophthalmologic, neurologic, digestive, limb ischaemia), the occurrence of an aortic complication (i.e. new or worsening of aortic dilation, aortic dissection), or new or worsening of vascular stenosis. RESULTS: From the cohort of 530 patients, 242 (45.7%) patients experienced relapse at least once, including 13 (2.5% of the cohort) who experienced severe relapse. Among the 464 recorded relapses, 14 (3% of all relapses) were severe. Severe relapse corresponded to the following vascular events: a peripheral limb ischaemia in 6 patients, a visual event in 3 patients (including 2 acute anterior ischaemic anterior neuropathies), an aortic complication in 3 patients, a mesenteric ischaemia in one patient and an ischaemic stroke in one patient.When compared with the 229 patients who experienced nonsevere relapses, severe relapse patients were younger at diagnosis (p= 0.02), more frequently showed limb claudication at baseline (p< 0.0001) and fewer GCA-related cranial signs (p< 0.0001). At diagnosis, more large-vessel vasculitis on imaging (82% vs 36%, p= 0.002) were observed in patients with severe relapse. The death rate did not differ between patients with severe and nonsevere relapses. CONCLUSION: In a real-life setting, relapse affects nearly half of GCA patients, but severe relapse is rare.

RESUMEN

BACKGROUND: The aim of this study was to investigate the influence of the time of pre-rehabilitation (PR) combined with respiratory training and aerobic exercise on surgical patients with lung cancer. PATIENTS AND METHODS: A retrospective study from a 5-year database of a single center, including patients with lung cancer who underwent surgery between 1 January 2016 and 31 December 2020, was conducted. The patients were divided into the PR group, in which they received the PR regimen, and the non-PR group, in which they received routine care. RESULTS: A total of 4452 patients were retrospectively included, 684 of whom received PR regimen. A lower postoperative pulmonary complication (PPC) rate was observed in PR group than in non-PR group before or after propensity score matching (PSM) (before: 12.6% vs 18.5%, P < 0.001; after: 12.6% vs 18.7%, P < 0.001). For the PR group, a restricted cubic spline model revealed a significant nonlinear dose‒response association between PR time and the occurrence of PPCs (P for nonlinearity = 0.002). The PR time associated with the lowest occurrence of PPCs was 7 days, and the odds ratio (OR) of PPCs decreased steeply, with an OR of 0.8 [95% confidence interval (CI) 0.66-0.97] per day until 7 days, and then remained stable with a slight increase afterward with an OR of 1.11 (95% CI 0.99-1.25) per day. CONCLUSION: The study validated the effectiveness of a pre-rehabilitation regimen for decreasing the occurrence of PPCs. A U-shaped nonlinear relationship was found between pre-rehabilitation time and the PPC rate, indicating that both excessive and insufficient pre-rehabilitation time may increase the incidence of PPCs. Registry Number: ChiCTR1800020097.

RESUMEN

BACKGROUND: Postoperative morbidity in patients undergoing curative colorectal cancer surgery is high. Prehabilitation has been suggested to reduce postoperative morbidity, however its effectiveness is still lacking. OBJECTIVE: The aim of this study was to investigate the effectiveness of prehabilitation in reducing postoperative morbidity and length of hospital stay in patients undergoing colorectal cancer surgery. METHODS: A comprehensive electronic search was conducted in the CINAHL, Cochrane Library, Medline, PsychINFO, AMED, and Embase databases from inception to April 2023. Randomised controlled trials testing the effectiveness of prehabilitation, including exercise, nutrition, and/or psychological interventions, compared with usual care in patients undergoing colorectal cancer surgery were included. Two independent review authors extracted relevant information and assessed the risk of bias. Random-effect meta-analyses were used to pool outcomes, and the quality of evidence was assessed using Grading of Recommendations, Assessment, Development, and Evaluations (GRADE) guidelines. RESULTS: A total of 23 trials were identified (N = 2475 patients), including multimodal (3 trials), exercise (3 trials), nutrition (16 trials), and psychological (1 trial) prehabilitation. There was moderate-quality evidence that preoperative nutrition significantly reduced postoperative infectious complications (relative risk 0.65, 95% confidence interval [CI] 0.45-0.94) and low-quality evidence on reducing the length of hospital stay (mean difference 0.87, 95% CI 0.17-1.58) compared with control. A single trial demonstrated an effect of multimodal prehabilitation on postoperative complication. CONCLUSION: Nutrition prehabilitation was effective in reducing infectious complications and length of hospital stay. Whether other multimodal, exercise, and psychological prehabilitation modalities improve postoperative outcomes after colorectal cancer surgery is uncertain as the current quality of evidence is low.

RESUMEN

BACKGROUND: Although sublobar resection (wedge resection [Wed] or segmentectomy [Seg]) has become a standard operative procedure for clinical stages IA1 and IA2 non-small cell lung cancer (NSCLC) in Japan, the impact of this procedure on the prognosis and postoperative complications in real-world clinical practice is unknown. METHODS: This study retrospectively analyzed risk factors for a poor prognosis and postoperative complications of 470 patients with clinical stage ≤ IA2 NSCLC who underwent surgery from 2012 to 2021. RESULTS: Among the patients with a consolidation-to-tumor ratio (CTR) higher than 0.5, the 5-year relapse-free survival (RFS) rate was significantly lower in the Wed group (72.1%) than in the Seg (85.8%) and Lob (86.8%) groups (p < 0.01), but the difference between the Seg and Lob groups was not significant. Among patients with a CTR of 0.5 or lower, the 5-year RFS rate did not differ significantly among the three groups. Multivariable analysis of RFS showed that the prognosis was significantly worse in the Wed group than in the Lob group (hazard ratio, 2.83; p < 0.01), but the difference between the Wed and Seg groups or the between Seg and Lob groups was not significant. Multivariable analysis of postoperative complications showed a significantly lower risk in the Wed group than in the Seg group (odds ratio, 0.31; p < 0.01). CONCLUSIONS: Seg could become the standard operative procedure for clinical stages IA1 and IA2 NSCLC patients. Wed is suggested to be an option for patients with a CTR of 0.5 or lower and has the advantage of avoiding postoperative complications.

RESUMEN

PURPOSE: To determine the association between pentosan polysulfate (PPS) use and the subsequent development of maculopathy in Asian population. DESIGN: A nationwide population-based retrospective cohort study using the Health Insurance Review and Assessment Service database. PARTICIPANTS: 103,553 individuals in the PPS user group and 205,792 individuals in the PPS non-user group, all newly diagnosed with cystitis between 2009 and 2020. METHODS: The association between PPS use and maculopathy was evaluated using a time dependent Cox proportional hazard model. Additionally, two sensitivity analyses were conducted by defining PPS users as individuals with an observation period over 6 months from the initial prescription or those with cumulative dose exceeding 9 g, employing the same analysis. MAIN OUTCOME MEASURES: The outcome measures included the hazard ratios (HR) representing the association between PPS use and maculopathy. RESULTS: PPS use was associated with an increased risk of subsequent maculopathy in univariate (HR, 1.7; 95% confidence intervals [CI], 1.66-1.75) and multivariate analysis (HR, 1.34; 95% CI, 1.31-1.38). These results were also confirmed in two sensitivity analyses. The mean cumulative dose of PPS for the cohort was 37.2 ± 76.7 g. CONCLUSIONS: In this nationwide cohort study involving an Asian population, individuals with cystitis using PPS exhibit an increased risk of developing subsequent maculopathy.

RESUMEN

INTRODUCTION: Left atrial appendage (LAA) closure (LAAC) is considered a viable alternative to anticoagulation therapy for stroke prevention in nonvalvular atrial fibrillation, we report a case with a less common shunt resulting from a device-related coronary artery-appendage fistula (CAAF) following LAAC. METHODS AND RESULTS: A 67-year-old male with a history of LAAC was referred to our emergency room with recurrent chest pain and palpitations and was diagnosed with ischemic angina pectoris. Subsequent coronary angiography (CAG) revealed 70% in-stent restenosis and an abnormal shunt of contrast originating from the left circumflex artery (LCA) to the LAA tip which did not exist before. The restenosis was successfully dilated using a drug-coated balloon, the procedure was safely completed without pericardial effusion. The patient had been implanted with a LAmbre occluder (Lifetech Scientific Corp.) in the previous LAAC procedure. This occluder had a lobe-disk design, and the distal umbrella was not fully opened after release, particularly in the lower portion. This could make the hooks embedded on the umbrella contact the LAA wall more tightly, possibly resulting in microperforation and coincidental impingement of the LCA. The epicardial adipose and hyperplastic tissue then chronically wrapped the perforated site, prevented blood outflow into the epicardium, and ultimately formed a CAAF. CONCLUSION: CAAF is a rare complication after LAAC but may be underestimated, especially for lobe-disk designed occluders. Therefore, CAG is perhaps necessary to detect this complication.

RESUMEN

INTRODUCTION: Pericardial effusion, a known complication to implantation of cardiac implantable electronic devices (CIED), may cause life-threatening cardiac tamponade. Limited knowledge is available about risk factors for clinically relevant procedural pericardial effusion. The aim is to identify the patient- and procedure-related risk factors associated with clinically relevant procedural pericardial effusion. METHOD: A nationwide observational cohort study based on data on 55 121 patients from the Danish Pacemaker Register between 2000 and 2018. We defined a clinically relevant procedural pericardial effusion related to the implantation if it occurred within 90 days after the primary CIED-procedure. Prespecified risk factors were analysed by multivariable logistic regression models to estimate the association with pericardial effusion. RESULTS: There were 115 (0.21%) patients diagnosed with clinically relevant procedural pericardial effusion, with a median age of 75 years and 38.3% were females. Of these, 80.9% lead to a subsequent pericardiocentesis procedure. In adjusted logistic regression analysis, an increased risk of clinically relevant pericardial effusion was associated with female sex (OR:1.49 [95%CI: 1.03-2.16]), heart failure (OR:1.54 [95%CI: 1.06-2.23]), previous cardiac surgery (OR:1.63 [95%CI: 1.05-2.55]), CRT-device (OR:2.05 [95%CI: 1.23-3.41]), tertiary-centres (OR:1.8 [95%CI: 1.18-2.73]), increased procedural volume per year (>1000) (OR:1.85 [95%CI: 1.03-3.30]), indication of device-implantation (atrioventricular block) (OR:2.37 [95CI: 1.45-3.87]), and increasing number of leads implanted (two leads (OR:2.39 [95%CI: 1.43-4.00]), three leads (OR:4.77 [95%CI: 2.50-9.10])). CONCLUSION: Clinically relevant procedural pericardial effusion is a rare complication after CIED-implantation in Denmark. This study reveals important patient- and procedure-related risk factors associated with clinically relevant procedural pericardial effusion.

RESUMEN

BACKGROUND: Type 1 diabetes (T1D) is a significant risk factor for a range of cardiovascular diseases. Nonetheless, the causal relationship between T1D and non-ischemic cardiomyopathy (NICM) remains to be elucidated. Furthermore, the mechanisms responsible for the progression from T1D to NICM have not been definitively characterized. OBJECTIVE: The aim of this study was to conduct a Mendelian randomization (MR) study to investigate the causal effects of T1D and its complications on the development of NICM. Additionally, this study aimed to conduct a mediation analysis to identify potential mediators within this correlation. METHODS: Genetic variants were used as instrumental variables for T1D. The summary data for T1D were obtained from two genome-wide association study datasets. The summary data for T1D with complications and NICM were obtained from the Finnish database. Two-sample MR, multivariable MR and mediation MR were conducted in this study. RESULTS: The study revealed a causal association between T1D, T1D with complications, and NICM (with odds ratios of 1.02, 95% CI 1.01-1.04, p = 1.17e-04 and 1.03, 95% CI 1.01-1.05, p = 3.15e-3). Even after adjusting for confounding factors such as body mass index and hypertension, T1D remained statistically significant (with odds ratio of 1.02, 95% CI 1.01-1.04, p = 1.35e-4). Mediation analysis indicated that monokine induced by gamma interferon may play a mediating role in the pathogenesis of T1D-NICM (mediation effect indicated by odds ratio of 1.005, 95% CI 1.001-1.01, p = 4.9e-2). CONCLUSION: The study demonstrates a causal relationship between T1D, its complications, and NICM. Additionally, monokine induced by gamma interferon may act as a potential mediator in the pathogenesis of T1D-NICM.

RESUMEN

OBJECTIVE: The aim of this study was to create a simple risk score to identify factors associated with wound complications after infrainguinal revascularization. METHODS: The Veterans Affairs Surgical Quality Improvement Program national data set was queried from 2005 to 2021 to identify 22,114 patients undergoing elective open revascularization for peripheral arterial disease (claudication, rest pain, tissue loss) or peripheral aneurysm. Emergency and trauma cases were excluded. The data set was divided into a two-thirds derivation set and one-third validation set to create a risk prediction model. The primary end point was wound complication (wound dehiscence, superficial/deep wound surgical site infection). Eight independent risk factors for wound complications resulted from the model and were assigned whole number integer risk scores. Summary risk scores were collapsed into categories and defined as low (0-3 points), moderate (4-7 points), high (8-11 points), and very high (>12 points). RESULTS: The wound complication rate in the derivation data set was 9.7% (n = 1428). Predictors of wound complication included age ≤73 (odds ratio [OR], 1.25; 95% confidence interval [CI], 1.08-1.46), body mass index ≥35 kg/m2 (OR, 1.99; 95% CI, 1.68-2.36), non-Hispanic White (vs others: OR, 1.48; 95% CI, 1.30-1.69), diabetes (OR, 1.23; 95% CI, 1.10-1.37), white blood cell count >9900/mm3 (OR, 1.18; 95% CI, 1.03-1.35), absence of coronary artery disease (OR, 1.27; 95% CI, 1.03-1.35), operative time >6 hours (OR, 1.20; 95% CI, 1.05-1.37), and undergoing a femoral endarterectomy in conjunction with bypass (OR, 1.34; 95% CI, 1.14-1.57). In both the derivation and validation sets, wound complications correlated with risk category. Among the defined categories in the derivation set, wound complication rates were 4.5% for low-risk patients, 8.5% for moderate-risk patients, 13.8% for high-risk patients, and 23.8% for very high-risk patients, with similar results for the internal validation data set. Operative indication did not independently associate with wound complications. Patients with wound complications had higher rates of reoperation and graft failure. CONCLUSIONS: This risk prediction model uses easily obtainable clinical metrics that allow for informed discussion of wound complication risk for patients undergoing open infrainguinal revascularization.

RESUMEN

OBJECTIVE: Respiratory adverse events (RAEs) after thoracic endovascular aortic repair (TEVAR) remain poorly characterized owing to the lack of comprehensive studies that identify individuals prone to these complications. This study aims to determine the incidence, factors associated with, and outcomes of RAEs after TEVAR. METHODS: We identified patients in the Vascular Quality Initiative undergoing TEVAR isolated to zones 0 to 5 from 2010 to 2023 for nontraumatic pathologies. After determining the incidence of postoperative RAEs, we assessed baseline characteristics, pathology, procedural details, and postoperative complications stratified by respiratory complication status: none, pneumonia only, reintubation only, or both. We then examined preoperative and intraoperative variables independently associated with the development of postoperative RAEs using multivariable modified Poisson regression. Kaplan-Meier analysis and Cox proportional hazards regression models were used to determine associations between postoperative RAEs and 5-year survival adjusting for preoperative variables and other nonrespiratory postoperative complications in a separate model. RESULTS: Of 10,708 patients, 8.3% had any RAE (pneumonia only, 2.1%; reintubation only, 4.8%; both, 1.4%). Patients with any RAE were more likely to present with aortic dissection (any respiratory complication, 46% vs no respiratory complication, 35%; P < .001), and be symptomatic (58% vs 48%; P < .001). Developing RAEs after TEVAR was associated with male sex (adjusted relative risk [aRR], 1.19; 95% confidence interval [CI], 1.01-1.41; P = .037), obesity (aRR, 1.31; 95% CI, 1.07-1.61; P = .009), morbid obesity (aRR, 1.68; 95% CI, 1.20-2.32; P = .002), renal dysfunction (aRR, estimated glomerular filtration rate 30-45, 1.45; 95% CI, 1.15-1.82; P = .002; estimated glomerular filtration rate <30/hemodialysis, 1.7; 95% CI, 1.37-2.11; P < .001), anemia (aRR, 1.31; 95% CI, 1.09-1.58; P = .003), aortic diameter >65 mm (aRR, 1.54; 95% CI, 1.25-1.89; P < .001), proximal disease in the aortic arch (aRR, 1.23; 95% CI, 1.03-1.48; P = .025) or ascending aorta (aRR, 1.61; 95% CI, 1.19-2.14; P = .002), acute aortic dissection (aRR, 2.13; 95% CI, 1.72-2.63; P < .001), ruptured presentation (aRR, 3.07; 95% CI, 2.43-3.87; P < .001), same-day surgical thoracic branch treatment (aRR, 1.51; 95% CI, 1.25-1.82; P < .001), chronic obstructive pulmonary disease on home oxygen (aRR, 1.58; 95% CI, 1.08-2.25; P = .014), limited self-care or bed-bound status (aRR, 2.12; 95% CI, 1.45-3.03; P < .001), and intraoperative transfusion (aRR, 1.88; 95% CI, 1.47-2.40; P < .001). Patients who developed postoperative RAEs had higher 30-day mortality (27% vs 4%; P < .001) and 5-year mortality than patients without respiratory complications (46% vs 20%; P < .001). After adjusting for preoperative and postoperative variables, the 5-year mortality was higher in patients who developed any postoperative RAE (adjusted hazard ratio [aHR], 1.8; 95% CI, 1.6, 2.1; P < .001), postoperative pneumonia only (aHR, 1.4; 95% CI, 1.0, 1.8; P = .046), reintubation only (aHR, 2.2; 95% CI, 1.8, 2.6; P < .001) or both (aHR, 1.5; 95% CI, 1.1, 2.0; P = .008). CONCLUSIONS: RAEs after TEVAR are common, more likely to occur in male patients with obesity, renal dysfunction, anemia, chronic obstructive pulmonary disease on home oxygen, acute aortic dissection, ruptured presentation, same-day surgical thoracic branch treatment, who received intraoperative transfusion, and are associated with a two-fold increase in 5-year mortality regardless of the development of other postoperative complications. Considering these factors in assessing the risks and benefits of TEVAR procedures, along with implementing customized postoperative care, can potentially improve clinical outcomes.

RESUMEN

STUDY QUESTION: What are the complications of transvaginal ethanol sclerotherapy for the treatment of endometriomas? SUMMARY ANSWER: Sclerotherapy is a reliable, minimally invasive method applicable in outpatient procedures but with specific and potential life-threatening complications that need to be identified and prevented. WHAT IS KNOWN ALREADY: There are currently few data on the use of transvaginal ethanol sclerotherapy, and we mainly note septic complications. STUDY DESIGN, SIZE, DURATION: A retrospective observational cohort study was carried out. The study was conducted at an academic hospital and included 126 women aged 31.9 ± 5.5 years (mean ± SD), between November 2013 and June 2021. We analyzed a total of 157 ethanol sclerotherapy treatment (EST), treated by 131 EST procedures, in 126 women. PARTICIPANTS/MATERIALS, SETTING, METHODS: The study included women with an indication for transvaginal ethanol sclerotherapy. Indications were women with at least one endometrioma over 10 mm, isolated or associated with other endometriosis locations, requiring treatment for pain or infertility before assisted reproductive treatment. We followed a standardized transvaginal ethanol sclerotherapy procedure consisting of an ultrasound-guided transvaginal puncture of one or more endometriomas under general anesthesia. The cyst content was completely removed and flushed with saline solution. Ethanol (96%) was injected at 60% of the initial volume of the endometrioma, remained in the cyst for 10 min and was then completely removed. Ethanol loss was defined as a loss of 5 ml or more than 10% of the initial volume of the injected ethanol. Failure was defined by the contraindication of endometrioma puncture because of interposition of the digestive tract, ethanol loss in the previous endometrioma treated (in case of multiple ESTs), failure to aspirate the endometriotic fluid, contraindication to start ethanol injection owing to saline solution leakage, or contraindication to continue ethanol injection owing to suspicions of ethanol leakage at sonography. Intraoperative complications were defined by ethanol loss, positive blood alcohol level, and ethanol intoxication. Postoperative complications were defined by fever, biological inflammatory syndrome, and ovarian abscess. Complications were classified according to the Clavien and Dindo surgical classification, which is a system for classifying postoperative complications in five grades of increasing severity. MAIN RESULTS AND THE ROLE OF CHANCE: We reported a total of 17/157 (10.8%) transvaginal ethanol sclerotherapy failures during 14/131 (10.7%) transvaginal ethanol sclerotherapy procedures in 13/126 (10.3%) women. In the same sets of data, complication was reported for 15/157 (9.5%) transvaginal ethanol sclerotherapy in 13/131 (9.9%) transvaginal ethanol sclerotherapy procedures in 13/126 (10.3%) women. Nine of 126 women (7.1%) had a grade I complication, one (0.8%) had a grade II complication (medical treatment for suspicion of pelvic infection), two (1.6%) had a grade III complication (ovarian abscess) and one (0.8%) had a grade IV complication (ethanol intoxication). We did not observe any grade V complications. LIMITATIONS, REASONS FOR CAUTION: This was a retrospective study and pain assessment not considered. The benefit-risk balance of endometrioma transvaginal ethanol sclerotherapy was not evaluated. WIDER IMPLICATIONS OF THE FINDINGS: Our study is the first to evaluate the complications of transvaginal ethanol sclerotherapy with such a large cohort of women in a standardized protocol. Transvaginal ethanol sclerotherapy seems to be an effective alternative to laparoscopic surgery in the management of endometriomas and limits the alteration of ovarian reserve. Transvaginal ethanol sclerotherapy is a reliable, minimally invasive method applicable on an outpatient basis. The majority of complications are Clavien-Dindo ≤IV, for which preventative measures, or at least early diagnosis and treatment, can be easily performed. The risk of ethanol intoxication is rare, but it is a life-threatening risk that must be avoided by appropriate implementation and promotion of the sclerotherapy procedures. STUDY FUNDING/COMPETING INTEREST(S): None. TRIAL REGISTRATION NUMBER: Aix Marseille University's ethics committee registration number 2021-06-03-01.

RESUMEN

Systemic lupus erythematosus (SLE) is a connective tissue disorder that affects various body systems. Both the innate and adaptive immunity contribute to the onset and progression of SLE. The main mechanism of SLE is an excessive immune response of immune cells to autoantigens, which leads to systemic inflammation and inflammation-induced organ damage. Notably, a subset of innate immune cells known as innate lymphoid cells (ILCs) has recently emerged. ILCs are pivotal in the early stages of infection; participate in immune responses, inflammation, and tissue repair; and regulate the immune function of the body by resisting pathogens and regulating autoimmune inflammation and metabolic homeostasis. Thus, ILCs dysfunction can lead to autoimmune diseases. This review discusses the maturation of ILCs, the potential mechanisms by which ILCs exacerbate SLE pathogenesis, and their contributions to organ inflammatory deterioration in SLE.
