RESUMEN

Opportunistic infections caused by various bacteria, viruses, fungi, or parasites can cause esophagitis. The fungus Candida albicans is often believed to be the thief behind this disorder. This condition's distinctive signs include the process of inflammation and the development of esophageal ulcers. The underlying immunodeficiency condition in HIV/AIDS patients, especially those in the late stages of the disease, may lead to severe illness or even death if the lowered immune system can no longer combat common infections. These individuals are, therefore, more at risk of contracting diseases like Candidiasis since they already have weakened immune systems. Furthermore, bacteria and mycobacteria can cause esophagitis in the same way that viruses can. Tobacco use, alcohol drinking, and nutritional deficiency are three additional problems that can lead to an HIV esophagitis infection. Complaints of inability to swallow, suffocating feeling or discomfort behind the breastbone, and painful swallowing are the primary symptoms of the patients. White plaques or ulcers observed in the esophagus during an endoscopy can be biopsied for further examination. The presence of C. albicans hyphae and inflammatory infiltrates in these samples confirms the diagnosis of HIV-associated esophagitis. Treatment involves the use of antifungal medications and addressing any underlying causes of esophagitis, which is linked to AIDS. For superficial to moderate infections, fluconazole is typically used first. If the disease is severe or recurs after treatment, intravenous amphotericin B may be necessary. Patients with recurring oral symptoms of HIV esophagitis might also need to take antifungal drugs as a preventative measure.

RESUMEN

BACKGROUND: The double burden of malnutrition, defined as the coexistence of obesity and malnutrition, is an increasing global health concern and is unclear in patients after ischemic stroke. The current study explored the combined impacts of obesity and malnutrition on patients with ischemic stroke. METHODS: We conducted a single-center prospective cohort study with patients with ischemic stroke enrolled in Minhang Hospital in China between January 2018 and December 2022. Patients were stratified into four categories based on their obesity (defined by body mass index) and nutritional status (classified according to the Controlling Nutritional Status score): (1) nourished nonobese, (2) malnourished nonobese, (3) nourished obese, and (4) malnourished obese. The primary end points were poor outcomes and all-cause mortality at 3 months. RESULTS: A total of 3160 participants with ischemic stroke were included in our study, of which 64.7% were male and the mean age was 69 years. Over 50% of patients were malnourished. At 3-month follow-up, the malnourished nonobese had the worst outcomes (34.4%), followed by the malnourished obese (33.2%), nourished nonobese (25.1%), and nourished obese (21.8%; P < 0.001). In multivariable analyses, with nourished nonobese group as the reference, the malnourished nonobese group displayed poorer outcomes (odds ratio [OR], 1.395 [95% CI, 1.169-1.664], P < 0.001) and higher all-cause mortality (OR, 1.541 [95% CI, 1.054-2.253], P = 0.026), but only a nonsignificant increase in poor prognosis rate (33.2% vs. 25.1%, P = 0.102) and mortality (4.2% vs. 3.6%, P = 0.902) were observed in the malnourished obese group. CONCLUSION: A high prevalence of malnutrition is observed in the large population suffering from ischemic attack, even in the obese. Malnourished patients have the worst prognosis particularly in those with severe nutritional status regardless of obesity, while the best functional outcomes and the lowest mortality are demonstrated in nourished obese participants.

RESUMEN

OBJECTIVE: Serum globulin is associated with inflammatory or immune disorders. However, it has not been established whether it is associated with myasthenia gravis (MG). We investigated the association between globulin with relapse and prognosis in children with MG. METHODS: A cohort of 148 MG cases and 150 healthy children were retrospectively enrolled from January 2015 to December 2021. Multivariate logistic and Cox regression models were used to analyze the treatment outcomes and recurrence of case group, exploring the influence of globulin. RESULTS: Compared with the control group, globulin levels in the MG group were slightly increased (t = 7.244, p < 0.001). After a mean follow-up of 2.25 ± 1.05 years, 35 cases relapsed, with a relapse rate of 23.65%. Logistic regression analysis showed that globulin levels at admission [adjusted odds ratio (OR) = 1.233, 95% confidence interval (CI) 1.028-1.472, p = 0.018] were independent risk factors for relapse. Cox regression analysis confirmed that globulin levels at admission affects relapse-free time [adjusted hazard ratio (HR) = 0.552, 95% CI 0.357-0.852, p = 0.007]. Receiver operating characteristic curve determined 25.10 as the optimal cutoff value for globulin. Cox regression showed that high globulin levels (>25.10) at admission (adjusted HR = 0.607, 95% CI 0.383-0.961, p = 0.033) were independent risk factors for poor therapeutic outcomes at follow-up. Ordinal logistic regression showed that globulin affects the treatment plan (OR = 1.445, 95% CI 1.223-1.847, p = 0.014). CONCLUSIONS: Elevated globulin levels in children with MG on admission predicts a high relapse rate and poor long-term therapeutic efficacies.

Serum globulin in children with myasthenia gravis: predicting relapse and prognosisFirst, the globulin in the MG children was higher than in the healthy controls, and there was some correlation between the globulin and the level of systemic inflammation.Second, globulin has been associated with relapse of MG in children. The higher the globulin, the higher the relapse rate and the shorter the time to prevent a relapse.Third, both initial and final globulin were related to the effect of MG in children, and the higher the long-term effect, the worse the long-term effect. It also influenced the change in treatment plan.

RESUMEN

Objective: To reveal the safety and efficacy of clipping and coiling in patients with ruptured distal anterior cerebral artery aneurysms (DACAA) and to calculate the risk factors affecting the two-year survival rate in follow-up patients. Methods: A retrospective study was conducted on the data of 140 patients (21 were lost to follow-up) with DACAA rupture who were treated by neurosurgery at 12 medical centers over a 2-year period, from January 2017 to December 2020. Univariate analysis was used to examine factors contributing to poor patient prognosis and to compare the prognosis of coiling and clipping treatments. Survival analysis was employed to compare survival rates between coiling and clipping, and risk factors affecting patient survival were analyzed using multivariate Cox regression analysis. Results: Out of 140 patients with ruptured DACAA, 80 (57.1%) were male, and 60 (42.9%) were female. A total of 111 (79.3%) patients were classified under Hunt-Hess scale grades I-III, while 95 (67.9%) were graded I-III according to the WFNs classification. Among them, 63 (45%) were treated with clipping, and 77 (55%) underwent coiling. Within 2 years of discharge from the hospital, 31 (59.6%) patients who underwent clipping and 54 (80.6%) who underwent coiling had a good prognosis. Multivariate Cox regression analysis revealed that only WFNs classification (I-III) was a protective factor influencing the 2-year survival of patients with ruptured DACAA. Conclusion: In the reality of medical practice, neurosurgeons are more likely to choose clipping as the treatment for cases with WFNs classification than or equal to III. There was no difference between clipping and coiling in the two-year prognosis at discharge. High priority should be given to DACAA cases with WFNs grading (I-III), as better outcomes can be achieved. The sample size will continue to be enlarged in the future to obtain more accurate findings. Abstracts for reviews, technical notes, and historical vignettes do not need to be separated into sections. They should begin with a clear statement of the paper's purpose followed by appropriate details that support the authors' conclusion(s).

RESUMEN

Approximately 10% of gastrointestinal stromal tumors (GISTs) harbor reportedly no KIT and PDGFRA mutations (wild-type GISTs). The clinicopathological features and oncologic outcomes of wild-type GISTs based on molecular profiles are unknown. We recruited 35 wild-type GIST patients from the two registry studies of high-risk GISTs between 2012 and 2015 and primary GISTs between 2003 and 2014. Molecular profiling of wild-type GISTs was performed by targeted next-generation sequencing (NGS) using formalin-fixed paraffin-embedded tumor samples. Among 35 wild-type GISTs, targeted NGS analysis detected NF1, SDH, or BRAF mutation: 16 NF1-GISTs with various NF1 mutations, 12 SDH-GISTs (4 with SDHA mutations, 4 with SDHB mutations, and 4 with SDHB-negative staining), and 5 BRAF-GISTs with the V600E mutation. Two GISTs showed no mutations based on our targeted NGS analysis. Additional gene mutations were infrequent in primary wild-type GISTs and found in TP53, CREBBP, CDKN2A, and CHEK2. Most NF1-GISTs were located in the small intestine (N = 12; 75%) and showed spindle cell features (N = 15; 94%) and multiple tumors (N = 6, 38%) with modest proliferation activities. In contrast, SDH-GISTs were predominantly found in the stomach (N = 11; 92%), exhibiting epithelioid cell (N = 6; 50%) and multiple (N = 6, 50%) features. The overall survival of patients with SDH-GISTs appeared to be better than that of BRAF-GISTs (p = 0.0107) or NF1-GISTs (p = 0.0754), respectively. In conclusion, major molecular changes in wild-type GISTs include NF1, SDH, and BRAF. NF1-GISTs involved multifocal spindle cell tumors in the small intestine. SDH-GISTs occurred in young patients and were multifocal in the stomach and clinically indolent.

RESUMEN

BACKGROUND AND AIMS: Limited evidence exists on the prognostic outcomes of the blood urea nitrogen to serum albumin ratio (B/A ratio) in congestive heart failure (CHF), particularly in developing countries with scarce heart failure epidemiological data. We aimed to investigate the association between B/A ratio and short-term outcomes in Chinese patients with CHF. METHODS AND RESULTS: We included 1761 CHF patients with available B/A ratio data from a cohort of 2008 patients. Patients were categorized into three groups based on B/A ratio (low to high). The primary endpoint was death or readmission within 28 days, and the secondary endpoint was death or readmission within 90 days. We employed restricted cubic spline analysis, Cox proportional hazards regression, and Kaplan-Meier curves to evaluate the relationship between B/A ratio at admission and the endpoints. Even after adjusting for other variables, higher B/A ratios were associated with increased rates of 28 days and 90 days mortality or readmission (HR: 2.4, 95% CI: 1.81-3.18 and HR: 1.74, 95% CI: 1.48-2.05). Significant differences in the risks of both primary and secondary endpoints were observed among the three B/A ratio groups. The association between B/A ratio and CHF was stable in the different subgroups (all P for interaction＞0.05). CONCLUSION: Higher B/A ratios are associated with an increased risk of short-term mortality or readmission in Chinese patients with CHF. The B/A ratio shows promise as a prognostic indicator for short-term outcomes in CHF patients.

RESUMEN

Background: Inflammation in the peritumoral normal tissues has impact on tumors. This study investigated the prognostic impact of portal area inflammation (PAI) on postoperative tumor recurrence and overall survival (OS) in patients undergoing resection for intrahepatic cholangiocarcinoma (ICC) without lymph node metastasis (LNM). Methods: Two hundred and ninety-seven patients who had undergone curative-intent resection at the Eastern Hepatobiliary Surgery Hospital, Shanghai, between 2011 and 2015 were selected. All patients were histologically diagnosed with ICC and had no LNM. PAI was defined by experienced pathologists based on standard pathological evaluations. Patients were divided into two groups according to the presence or absence of PAI. Further survival analysis was performed on PAI-related endpoints, OS, and recurrence-free survival (RFS), using Kaplan-Meier analysis and multivariate regression. Results: Among the 297 patients included in the study, the PAI incidence was 43.1% (128 patients). OS and RFS were worse in patients with PAI than in those without PAI (median OS, 21.87 months with PAI versus 33.37 months without PAI, P<0.001; median RFS, 12.33 months with PAI versus 21.60 months without PAI, P<0.001). Multivariate analysis revealed that PAI was an independent prognostic factor for both OS [hazard ratio (HR) 1.60; 95% confidence interval (CI): 1.18-2.17, P=0.003] and RFS (HR 1.40; 95% CI: 1.06-1.85, P=0.019). Conclusions: Consequently, PAI is a strong independent predictor of tumor recurrence and OS after curative-intent resection in patients with ICC without LNM. The impact of PAI on the postoperative prognosis of ICC patients without LNM is non-negligible. It is strongly recommended to pay attention to the inflammatory status of the portal area in ICC patients and increase the frequency of postoperative follow-up to improve the prognosis of ICC patients after curative resection.

RESUMEN

N6-methyladenosine (m6A) RNA methylation, a dynamic regulator of transcript expression, plays a pivotal role in cancer by influencing diverse mRNA processes, including nuclear export, splicing, translation and decay. It intersects with cancer biology, impacting progression, treatment sensitivity and prognosis. Platinum-based compounds are essential in cancer treatment, while intrinsic or acquired resistance poses a formidable challenge, limiting therapeutic efficacy. Recent breakthroughs have established a direct association between m6A RNA methylation and platinum resistance in various cancer types. This review summarized related studies, aiming to provide profound insights into the interplay between m6A-associated regulation and platinum-resistance mechanisms in cancer. It explores therapeutic approaches, including personalized treatments based on m6A profiles, guiding future research to enhance clinical strategies for oncological prognostic outcomes.

Cancer poses a global health challenge, with platinum-based drugs as a cornerstone of treatment. Regrettably, cancer cells can develop resistance to these drugs, diminishing their effectiveness. Recent research suggests that a subtle modification known as N⁶-methyladenosine (m6A) on RNA molecules may contribute to this resistance. m6A acts as a minuscule tag on RNA molecules within the cells, akin to a genetic switch. When altered, it can render cancer cells less responsive to platinum-based drugs. Scientists have found that m6A changes in various cancer types can bolster resistance to platinum-based drugs. This reduced drug efficacy presents a significant concern, as platinum-based drugs are vital in treating diverse cancer types, including ovarian, lung and colorectal cancer. Understanding the impact of m6A on platinum resistance is pivotal. It may enable doctors to identify patients less likely to respond to treatment. Researchers are also investigating methods to target m6A alterations in cancer cells, potentially rendering them more receptive to platinum-based drugs. Ongoing research into m6A and its role in platinum resistance holds promise for enhancing cancer treatments, ultimately increasing the chances of success for patients requiring platinum-based drugs.

RESUMEN

PURPOSE: The purpose of this study was to conduct a matched-pair analysis to assess the impact of radiotherapy (RT) on patients with malignant tracheal tumors using the surveillance, epidemiology, and end results database. Additionally, a predictive nomogram was developed for patients with malignant tracheal tumors. METHODS: Propensity score matching (PSM) was used to minimize bias between the RT and no-RT groups. We utilized both univariate and multivariate Cox proportional hazards regression analyses to identify independent prognostic factors for patients and subgroups. We developed a novel nomogram and evaluated its results using the C-index. RESULTS: A total of 648 patients between 1975 and 2019 were included, and 160 patients in RT were 1:1 propensity score-matched with no-RT. The independent prognostic factors for patients with tracheal malignant tumors were surgery, marital status, disease extension, pathology, and age. The independent risk factors for patients without surgery included RT and disease extension. The C-index confirmed that the nomogram accurately predicted the prognosis of patients with tracheal malignant tumors. CONCLUSIONS: Our findings suggest that RT may provide a survival benefit for tracheal cancer patients who did not undergo surgery. The nomogram can be a useful tool for predicting prognosis in patients with tracheal malignant tumors.

RESUMEN

BACKGROUND: Standard modifiable risk factors (SMuRFs) increase the risk of cardiovascular events in patients with acute coronary syndrome (ACS) and are also strongly associated with obstructive sleep apnea (OSA) in a bidirectional relationship. However, the association of OSA with recurrent cardiovascular events in ACS patients based on the number of SMuRFs remains unclear. Hence, we aimed to elucidate the prognostic implication of OSA in ACS patients stratified by the number of SMuRFs. METHODS: This was a post hoc analysis of the OSA-ACS study (NCT03362385), including 1927 patients admitted for ACS and undergoing portable sleep monitoring. OSA was defined as an apnea hypopnea index ≥ 15 events/h. The primary endpoint was major adverse cardiovascular and cerebrovascular event (MACCE) including cardiovascular death, myocardial infarction, stroke, hospitalization for unstable angina or heart failure, and ischemia-driven revascularization. Cox proportional hazards model and Kaplan-Meier analysis were used to investigated the relationship between OSA and subsequent cardiovascular events after patients were stratified by the number of SMuRFs. RESULTS: Among 1927 patients enrolled, 130 (6.7%) had no SMuRF, 1264 (65.6%) exhibited 1-2 SMuRFs and 533 (27.7%) presented 3-4 SMuRFs. With the increase of the number of SMuRFs, the proportion of OSA in ACS patients tended to increase (47.7% vs. 51.5% vs. 56.6%), but there was no significant difference between them (P = 0.08). After the stratification of ACS patients via SMuRF numbers and adjustment for confounding factors, fully adjusted Cox regression indicated that OSA increased the risk of MACCE (adjusted HR, 1.65; 95%CI, 1.06-2.57; P = 0.026) and ischemia-driven revascularization (adjusted HR, 2.18; 95%CI, 1.03-4.65; P = 0.042) in ACS patients with 3-4 SMuRFs. CONCLUSIONS: In hospitalized ACS patients, OSA is associated with an increased risk of MACCE and ischemia-driven revascularization among patients with 3-4 SMuRFs. Therefore, screening for OSA should be emphasized in ACS patients with 3-4 SMuRFs, and intervention trials should be prioritized in these high-risk patients.

RESUMEN

BACKGROUND: The double burden of malnutrition, described as the coexistence of malnutrition and obesity, is a growing global health issue. This study examines the combined effects of obesity and malnutrition on patients with acute myocardial infarction (AMI). METHODS: Patients presenting with AMI to a percutaneous coronary intervention-capable hospital in Singapore between January 2014 and March 2021 were retrospectively studied. Patients were stratified into the following: (1) nourished nonobese, (2) malnourished nonobese, (3) nourished obese, and (4) malnourished obese. Obesity and malnutrition were defined according to the World Health Organization definition (body mass index ≥27.5 kg/m2) and Controlling Nutritional Status score, respectively. The primary outcome was all-cause mortality. The association between combined obesity and nutritional status with mortality was examined using Cox regression, adjusted for age, sex, AMI type, previous AMI, ejection fraction, and chronic kidney disease. Kaplan-Meier curves for all-cause mortality were constructed. RESULTS: The study included 1829 AMI patients, of which 75.7% were male and mean age was 66 years. Over 75% of patients were malnourished. Majority were malnourished nonobese (57.7%), followed by malnourished obese (18.8%), nourished nonobese (16.9%), and nourished obese (6.6%). Malnourished nonobese had highest all-cause mortality (38.6%), followed by the malnourished obese (35.8%), nourished nonobese (21.4%), and nourished obese (9.9%, P<0.001). Kaplan-Meier curves demonstrated least favorable survival in malnourished nonobese group, followed by malnourished obese, nourished nonobese, and nourished obese. With nourished nonobese group as the reference, malnourished nonobese had higher all-cause mortality (hazard ratio, 1.46 [95% CI, 1.10-1.96], P=0.010), but only a nonsignificant increase in mortality was observed in the malnourished obese (hazard ratio, 1.31 [95% CI, 0.94-1.83], P=0.112). CONCLUSIONS: Among AMI patients, malnutrition is prevalent even in the obese. Compared to nourished patients, malnourished AMI patients have a more unfavorable prognosis especially in those with severe malnutrition regardless of obesity status, but long-term survival is the most favorable among nourished obese patients.

RESUMEN

AIM: To examine the prevalence and prognosis of hepatic steatosis and fibrosis in post-acute myocardial infarction (AMI) patients. METHODS: Patients presenting with AMI to a tertiary hospital were examined from 2014 to 2021. Hepatic steatosis and advanced hepatic fibrosis were determined using the Hepatic Steatosis Index and fibrosis-4 index, respectively. The primary outcome was all-cause mortality. Cox regression models identified determinants of mortality after adjustments and Kaplan-Meier curves were constructed for all-cause mortality, stratified by hepatic steatosis and advanced fibrosis. RESULTS: Of 5765 patients included, 24.8% had hepatic steatosis, of whom 41.7% were diagnosed with advanced fibrosis. The median follow-up duration was 2.7 years. Patients with hepatic steatosis tended to be younger, female, with elevated body mass index and an increased metabolic burden of diabetes, hypertension and hyperlipidaemia. Patients with hepatic steatosis (24.6% vs. 20.9% mortality, P < .001) and advanced fibrosis (45.6% vs. 32.9% mortality, P < .001) had higher all-cause mortality rates compared with their respective counterparts. Hepatic steatosis (adjusted hazard ratio 1.364, 95% CI 1.145-1.625, P = .001) was associated with all-cause mortality after adjustment for confounders. Survival curves showed excess mortality in patients with hepatic steatosis compared with those without (P = .002). CONCLUSIONS: Hepatic steatosis and advanced fibrosis have a substantial prevalence among patients with AMI. Both are associated with mortality, with an incrementally higher risk when advanced fibrosis ensues. Hepatic steatosis and fibrosis could help risk stratification of AMI patients beyond conventional risk factors.

RESUMEN

OBJECTIVE: This study assessed the effect of omentectomy on the prognosis and fertility in patients with clinically early-stage (I, II) malignant ovarian germ cell tumours (MOGCT). DESIGN: A retrospective multicentre study. SETTING: Four university teaching hospitals in China. POPULATION: A total of 268 patients with clinically apparent early-stage (I, II) MOGCT. METHODS: Data were obtained from the medical records. Additionally, the propensity score matching (PSM) algorithm was adopted. MAIN OUTCOME MEASURES: Prognostic outcomes were disease-free survival (DFS) and overall survival (OS). Fertility outcomes were pregnancy and live birth rates. RESULTS: A total of 187 (69.8%) patients underwent omentectomy. Kaplan-Meier analysis showed no significant differences in DFS and OS between the omentectomy and non-omentectomy groups before and after PSM (p > 0.05). Additionally, subgroup analysis stratified by age (<18 and ≥18 years) showed similar results. International Federation of Gynecology and Obstetrics (FIGO) stage was the only risk factor associated with DFS (hazard ratio [HR] 14.71, 95% confidence interval [CI] 4.47-48.38, p < 0.001) and OS (HR 37.36, 95% CI 3.87-361.16, p = 0.002). Pregnancy and live birth rates in the total population were 80.3% and 66.7%, respectively. There were no significant differences between the two groups before and after PSM. CONCLUSIONS: Omentectomy did not improve survival or affect fertility in patients with clinically apparent early-stage (I, II) MOGCT, regardless of the age. The clinical FIGO stage was an independent risk factor for recurrence and death.

RESUMEN

A sizeable number of patients without standard modifiable cardiovascular risk factors (SMuRFs), such as hypertension, diabetes, hypercholesterolemia and smoking, suffer from acute coronary syndrome (ACS). These SMuRF-less patients have high short-term morbidity and mortality. We compared both short- and long-term outcomes of SMuRF-less and SMuRF ACS patients in a multi-ethnic Asian cohort.This was a retrospective study of patients with first ACS from 2011 to 2017. The primary outcome was long-term all-cause mortality. Secondary outcomes were 30-day all-cause mortality, cardiac-mortality, unplanned cardiac readmission, cardiogenic shock, heart failure, and stroke. Subgroup analysis was carried out by sex and ACS type.Of 5400 patients, 8.6% were SMuRF-less. The median follow-up time was 6.3 years (interquartile range [IQR] 4.2-8.2 years). SMuRF-less patients were younger and tended to present with ST-segment elevation myocardial infarction (STEMI). They were more likely to require inotropic support, intubation, and have cardiac arrest. At 30 days, SMuRF-less patients had higher rates of all-cause mortality, cardiac-related mortality and cardiogenic shock, but lower rates of heart failure. At 6 years, all-cause mortality was similar in both groups (18.0% versus 17.1% respectively, p = 0.631). Kaplan-Meier curves showed increased early mortality in the SMuRF-less group, but the divergence in survival curves was no longer present in the long-term. The absence of SMuRF was an independent predictor of mortality, regardless of sex or ACS type.In a multi-ethnic cohort of patients with ACS, SMuRF-less patients were observed to have higher mortality than SMuRF patients during the early stages which was attenuated over time.

RESUMEN

OBJECTIVE: Emerging evidence supports the favorable cardiovascular health in nonobese subjects with healthy metabolism. However, little is known regarding the prognosis across the range of metabolic phenotypes once cardiovascular disease is established. We examined the prognosis of patients with acute myocardial infarction (AMI) stratified according to metabolic health and obesity status. METHODS: This is a retrospective study on consecutive patients with AMI admitted to a tertiary hospital between 2014 and 2021. Patients were allocated into the following 4 groups based on metabolic and obesity profile: (1) metabolically healthy obese (MHO), (2) metabolically healthy nonobese (MHNO), (3) metabolically unhealthy obese (MUO), and (4) metabolically unhealthy nonobese (MUNO). Metabolic health was defined in accordance to the Biobank Standardisation and Harmonisation for Research Excellence in the European Union Healthy Obese Project. The primary outcome was all-cause mortality. The Cox regression analysis examined the independent association between mortality and metabolic phenotypes, adjusting for age, sex, AMI type, chronic kidney disease, smoking status, and left ventricular ejection fraction. RESULTS: Of 9958 patients, the majority (68.5%) were MUNO, followed by MUO (25.1%), MHNO (5.6%), and MHO (0.8%). MHO had the lowest mortality (7.4%), followed by MHNO (9.7%), MUO (19.2%), and MUNO (22.6%) (P < .001). Compared with MHNO, MUO (hazard ratio [HR], 1.737; 95% confidence interval [CI], 1.282-2.355; P < .001) and MUNO (HR, 1.482; 95% CI, 1.108-1.981; P = .008) had a significantly higher mortality risk but not MHO (HR, 1.390; 95% CI, 0.594-3.251; P = .447), after adjusting for confounders. The Kaplan-Meier curves showed favorable survival in the metabolically healthy and obesity groups, with the highest overall survival in the MHO, followed by MHNO, MUO, and MUNO (P < .001). CONCLUSION: Metabolically healthy and obese patients with AMI have favorable prognosis compared with metabolically unhealthy and nonobese patients. It is equally important to prioritize intensive metabolic risk factor management to weight reduction in the early phase after AMI.

RESUMEN

Background: An increasing proportion of patients with acute myocardial infarction (AMI) are presenting without standard modifiable risk factors (SMuRFs) of hypertension, hypercholesterolemia, diabetes, and smoking, but with an unexpectedly increased mortality. This study examined the SMuRF-less patients presenting with AMI in a multiethnic Asian population. Methods: We recruited patients presenting with AMI from 2011 to 2021 and compared the prevalence, clinical characteristics, and outcomes of SMuRF-less and SMuRF patients. Multivariable analysis was used to compare the outcomes of 30-day cardiovascular mortality, all-cause mortality, readmission, cardiogenic shock, stroke, and heart failure. Kaplan-Meier curves were constructed for 30-day cardiovascular mortality, with stratification by ethnicity, gender and AMI type, and 10-year all-cause mortality. Results: Standard modifiable risk factor-less patients, who made up 8.6% of 8,680 patients, were significantly younger with fewer comorbidities that include stroke and chronic kidney disease, but higher rates of ventricular arrhythmias and inotropic or invasive ventilation requirement. Multivariable analysis showed higher rates of cardiovascular mortality (HR 1.48, 95% CI: 1.09-1.86, p = 0.048), cardiogenic shock (RR: 1.31, 95% CI: 1.09-1.52, p = 0.015), and stroke (RR: 2.51, 95% CI: 1.67-3.34, p = 0.030) among SMuRF-less patients. A 30-day cardiovascular mortality was raised in the SMuRF-less group, with similar trends in men, patients with ST-segment elevation myocardial infarction (STEMI), and the three Asian ethnicities. All-cause mortality remains increased in the SMuRF-less group for up to 5 years. Conclusion: There is a significant proportion of patients with AMI without standard risk factors in Asia, who have worse short-term mortality. This calls for greater focus on the management of this unexpectedly high-risk subgroup of patients.

RESUMEN

INTRODUCTION: The Cancer Patient Pathway for Non-specific Symptoms and Signs of Cancer (NSSC-CPP) has been implemented in Denmark with regional and intra-regional differences. In some places, the initial diagnostic work-up (often including a CT scan) is performed by general practitioners (GPs) and in others by hospitals. Variations may influence the use of Organ Specific Cancer Patient Pathways (OS-CPPs) and prognostic outcomes for the patients. Therefore, the aims were: 1) To analyse how a CT scan referred from GP or hospital is followed by OS-CPPs and NSSC-CPPs at the national and regional level, and 2) To analyse, nationally and regionally, the diagnostic outcomes of persons referred to CT scan by either GP or hospital six months after and mortality one year after CT scan. METHODS: A nationwide population-based study including individuals with a first CT scan in 2013-2016, either referred from GP or hospital. RESULTS: Overall, individuals with a CT scan referred from GPs were more likely to start a NSSC-CPP or an OS-CPP than individuals with a CT scan referred by hospitals. Across the five Regions in Denmark, CT scans referred by GPs were associated with reduced odds of total mortality in all regions; (North, OR=0.78 [0.73 0.83], Central, OR=0.92 [0.87 0.96], South, OR=0.85 [0.81 0.89], Capital, OR=0.96 [0.91 1.00] and Zealand, OR=0.85 [0.79 0.90]) and increased odds of cancer-specific mortality in four regions, ORs ranging from 1.15-1.51 with no difference in Region North (1.00 [0.91 1.10]). CONCLUSION: No obvious association between more CT scans and CPPs and reduced diagnoses and mortality was observed. The different diagnostic models might not explain the prognostic outcomes, but the different use of CT scans in, and between Regions play a large role in the differences in incidence and mortality.

RESUMEN

Literature of patients with severe high-gradient aortic stenosis (HG AS) (mean pressure gradient [MPG] ≥ 40 mmHg and aortic valve area [AVA] ≥ 1.0 cm2) remains limited. This study seeks to compare the prognostic outcomes of patients with high-gradient concordant (HGCON-AS) and discordant AS (HGDIS-AS) in an Asian cohort. From 2010 to 2015, patients with moderate-to-severe AS with preserved left ventricular ejection fraction (LVEF ≥ 50%) were recruited and stratified into 3 groups based on index echocardiogram-(1) HGDIS-AS, (2) HGCON-AS and (3) moderate AS (MOD-AS). The primary study endpoints was all-cause mortality, with secondary endpoints of congestive heart failure (CHF) admissions and aortic valve replacement (AVR). Multivariable Cox regression was used and Kaplan-Meier curves were constructed to evaluate associations between HGDIS-AS, HGCON-AS and MOD-AS, and the study outcomes. A total of 467 patients were studied, comprising of 6.2% HGDIS-AS, 13.9% HGCON-AS and 79.9% MOD-AS patients. There was significantly higher AVR rates in the HGCON-AS group (58.5%), followed by HGDIS-AS (31.0%) and MOD-AS (4.6%), p < 0.001) groups. After adjusting for confounders, HGCON-AS was significantly associated with all-cause mortality (HR 3.082, 95% CI 1.479-6.420, p = 0.003) and CHF admissions (HR 12.728, 95% CI 2.922-55.440 p = 0.001) but not HGDIS-AS, with MOD-AS as the reference group. Both HGDIS-AS (HR 7.715, 95% CI 2.927-20.338; p < 0.001) and HGCON-AS (HR 21.960, 95% CI 10.833-44.515, p < 0.001) were independent predictors of AVR. After exclusion of reversible high-flow states, HGDIS-AS patients appear to have a more favourable prognostic profile compared to HGCON-AS patients. Large prospective interventional studies examining the prognostic differences between the two groups will be the next important step.

RESUMEN

Background: To compare the merits and safety between conscious sedation/monitored anesthesia (CS/MAC) and general anesthesia (GA) for patients receiving transcatheter aortic valve replacement (TAVR). Measurements: Databases including EMBASE, MEDLINE, and the Cochrane Library databases were searched from inception to October 2022 to identify studies investigating the impact of CS/MAC on peri-procedural and prognostic outcomes compared to those with GA. The primary outcome was the association of CS/MAC with the risk of 30-day mortality, while secondary outcomes included the risks of adverse peri-procedural (e.g., vasopressor/inotropic support) and post-procedural (e.g., stroke) outcomes. Subgroup analysis was performed based on study design [i.e., cohort vs. matched cohort/randomized controlled trials (RCTs)]. Main results: Twenty-four studies (observational studies, n = 22; RCTs, n = 2) involving 141,965 patients were analyzed. Pooled results revealed lower risks of 30-day mortality [odd ratios (OR) = 0.66, p < 0.00001, 139,731 patients, certainty of evidence (COE): low], one-year mortality (OR = 0.72, p = 0.001, 4,827 patients, COE: very low), major bleeding (OR = 0.61, p = 0.01, 6,888 patients, COE: very low), acute kidney injury (OR = 0.71, p = 0.01, 7,155 patients, COE: very low), vasopressor/inotropic support (OR = 0.25, p < 0.00001, 133,438 patients, COE: very low), shorter procedure time (MD = -12.27 minutes, p = 0.0006, 17,694 patients, COE: very low), intensive care unit stay (mean difference(MD) = -7.53 h p = 0.04, 7,589 patients, COE: very low), and hospital stay [MD = -0.84 days, p < 0.00001, 19,019 patients, COE: very low) in patients receiving CS/MAC compared to those undergoing GA without significant differences in procedure success rate, risks of cardiac-vascular complications (e.g., myocardial infarction) and stroke. The pooled conversion rate was 3.1%. Results from matched cohort/RCTs suggested an association of CS/MAC use with a shorter procedural time and hospital stay, and a lower risk of vasopressor/inotropic support. Conclusion: Compared with GA, our results demonstrated that the use of CS/MAC may be feasible and safe in patients receiving TAVR. However, more evidence is needed to support our findings because of our inclusion of mostly retrospective studies.
