Association of Lipoprotein(a) With Changes in Coronary Atherosclerosis in Patients Treated With Alirocumab.

Elevated Lp(a) (lipoprotein[a]) is a risk marker for atherosclerotic disease, but the underlying mechanisms remain elusive. We examined the association of Lp(a) with changes in coronary atherosclerosis following intensive lipid-lowering therapy. In the PACMAN-AMI trial (Effects of the PCSK9 Antibody Alirocumab on Coronary Atherosclerosis in Patients With Acute Myocardial Infarction), 300 patients with acute myocardial infarction were randomized to receive biweekly alirocumab 150 mg or placebo in addition to high-intensity statins. Patients underwent serial 2-vessel intravascular ultrasound, optical coherence tomography, and near-infrared spectroscopy in the non-infarct-related arteries at baseline and after 52 weeks. The main end points were percent atheroma volume by intravascular ultrasound, minimum fibrous cap thickness by optical coherence tomography, and maximum lipid core burden index within 4 mm (maxLCBI4mm) by near-infrared spectroscopy. A total of 265 patients had serial intravascular ultrasound data (mean age, 58±9 years; 16% women). Alirocumab resulted in greater reductions in percent atheroma volume and maxLCBI4mm, as well as a greater increase in minimum fibrous cap thickness, compared with placebo. In the alirocumab group, the reduction in maxLCBI4mm was smaller in patients with higher baseline Lp(a), defined by the highest quartile (Q4, ≥98 nmol/L; n=30), than in those with lower baseline Lp(a) (Q1-Q3, <98 nmol/L; n=99; -40.2 [-91.1 to 10.7] versus -91.4 [-113.9 to -68.9], respectively; P=0.01 after adjustment for clinically relevant baseline variables), and was comparable to the maxLBI4mm reduction in the placebo group (-37.60 [-57.40 to -17.80]; n=134). These findings were consistent when higher baseline Lp(a) was defined by cut-off values of ≥75 versus <75 nmol/L (n=35 versus 94, respectively, in the alirocumab group) and ≥125 versus <125 nmol/L (n=23 versus 106, respectively). Changes in percent atheroma volume and minimum fibrous cap thickness did not differ in relation to baseline Lp(a). In patients with acute myocardial infarction, elevated Lp(a) at baseline is associated with attenuation of plaque lipid regression despite intensive treatment with alirocumab plus high-intensity statin. This finding may explain the residual cardiovascular risk associated with high Lp(a) despite optimal control of lipid levels. URL: https://www.clinicaltrials.gov; Unique identifier: NCT03067844.

Epicardial Access for Ventricular Tachycardia and Premature Ventricular Complexes Ablation – An Institutional Experience.

BackgroundEpicardial access for Ventricular Arrhythmia (VA) ablation is a challenging and relatively uncommon procedure during ventricular ablation. ObjectiveThis study aims to assess the outcomes, predictors of success, and complications associated with pericardial access during these procedures. MethodsThis multicenter, retrospective, observational study includes data collected over twenty years (2004–2024) from all Mayo Clinic sites performing VA ablation with epicardial access. ResultsWith 196 for VT and 69 for PVC ablations respectively A total of 265 patients were included in the analysis: 196 for VT ablation and 69 for PVC ablation. Among them, 184(69%) had at least one previous VA ablation, 51 (19.2%) had ischemic cardiomyopathy (ICM), 53(20%) had structurally normal hearts, and 164 (61.9%) had nonischemic cardiomyopathies (NICM). Three presented with concomitant ICM and NICM. Within the NICM group, the most common diagnoses were dilated cardiomyopathy (n=80, 30.2%), arrhythmogenic right ventricular cardiomyopathy (n=34, 12.8%), and sarcoidosis (n=15, 5.7%).Acute success, defined as noninducibility, was achieved in 100 (61.7%) out of 162 patients tested, while partial success (clinical arrhythmia noninduciblility) was observed in 47(29%). Before discharge, VT recurred in 20 patients (10.2%).During a median follow-up of 61 months, events were observed as follows:, 60 patients (35.5%) died, 26(13.3%) underwent heart transplantation, and 62 (31.6%) required a repeat ablation for VAs. Event-free survival rates were 50% (CI: 43-58%) at one year. ConclusionsSuccessful VT ablation with Epicardial access can be achieved in select cases, though event-free survival remains suboptimal. Advanced disease stage and persistent inducibility at the end of the procedure are predictors of poor outcomes.

Impact of the Coronavirus Disease 2019 [COVID-19] Pandemic on Post-Acute Care of Patients with Heart Failure and the Effectiveness of Vaccine Prevention.

The Heart Failure Post-Acute Care [HF-PAC] program is a specialized healthcare program aimed at providing comprehensive care and support for patients with heart failure [HF] as they transition from acute hospital settings to home. But the impact of the coronavirus disease 2019 [COVID-19] pandemic on the HF-PAC program remains unknown. Furthermore, the effects of the comprehensive COVID-19 vaccination program on these patients with HF-PAC warrants further investigation. A total of 265 patients with acute decompensated HF were admitted to the hospital between May 2020 and October 2022. Of these, 159 patients underwent planned HF-PAC follow-up for 6 months, followed by scheduled follow-up visits every 3 months and unscheduled telephone randomized visits for at least another 6 months. The program completion rate was nearly 92%. COVID-19 significantly impacted patients with HF-PAC, leading to an increased mortality [13.3%] compared to before the pandemic [6.5%]. In our patient cohort, 83% had received at least 1 dose of vaccine and 61% had received > 3 doses. Of these patients with HF-PAC, 34% contracted COVID-19 infection post discharge, and 8.8% died owing to the infection. Of the mortality group, 42.9% patients were not vaccinated, and 28.6% received 1 vaccine dose, and their vaccination rate was lower than in the survival group [p = 0.01]. The COVID-19 pandemic had a significant impact on patients enrolled in the HF-PAC program; receiving more than 3 doses of the COVID-19 vaccine was associated with a significant reduction in mortality rates among these patients.

Aromatase, testosterone, TMPRSS2: determinants of COVID-19 severity

BackgroundMale sex has been identified as a risk factor for worse COVID-19 outcomes. This sex difference has been mostly attributed to the complex role of sex hormones. Cell surface entry of SARS-CoV-2 is mediated by the transmembrane protease serine 2 (TMPRSS2) which is under transcriptional regulation by androgens. P450 aromatase enzyme converts androgens to estrogens. This study measured concentrations of aromatase enzyme, testosterone, estradiol, and TMPRSS-2 in plasma of hospitalized COVID-19 patients to elucidate the dynamics of sex-linked disparity in COVID-19 and correlate them with disease severity and mortality.MethodsIn this prospective cohort study, a total of 265 patients (41% women), age 18 years and older, who had a positive COVID-19 PCR test and were hospitalized for COVID-19 at Memorial Hermann Hospital in Houston, (between May 2020 and May 2021) were enrolled in the study if met inclusion criteria. Plasma concentrations of Testosterone, aromatase, TMPRSS-2, and estradiol were measured by ELISA. COVID-19 patients were dichotomized based on disease severity into moderate-severe (n = 146) or critical (n = 119). Mann Whitney U and logistic regression were used to correlate the analytes with disease severity and mortality.ResultsTMPRSS2 (2.5 ± 0.31 vs. 1.73 ± 0.21 ng/mL, p < 0.01) and testosterone (1.2 ± 0.1 vs. 0.44 ± 0.12 ng/mL, p < 0.01) were significantly higher in men as compared to women with COVID-19 after adjusting for age in a multivariate model. There was no sex difference seen in the level of estradiol and aromatase in COVID-19 patients. TMPRSS2 and aromatase were higher, while testosterone was lower in patients with increased COVID-19 severity. They were independently associated with COVID-19 severity, after adjusting for several baseline risk factors in a multivariate logistic regression model. In terms of mortality, TMPRRS2 and aromatase levels were significantly higher in non-survivors.ConclusionsOur study demonstrates that testosterone, aromatase, and TMPRSS2 are markers of COVID-19 severity. Estradiol levels do not change with disease severity in COVID-19. In terms of mortality prediction, higher aromatase and TMPRSS-2 levels can be used to predict mortality from COVID-19 in hospitalized patients.Plain English SummaryCOVID-19 has caused over a million deaths in the U.S., with men often getting sicker than women. Testosterone, a male hormone, helps control a protein called TMPRSS-2, which allows the COVID-19 virus to spread more easily in the body. A protein called aromatase converts the male hormone testosterone into the female hormone estrogen. It is thought that female hormone estrogen helps protect women from getting seriously ill from COVID-19. To understand the role of these hormones in COVID-19 and sex differences, we measured levels of testosterone, estrogen, aromatase (which turns testosterone into estrogen), and TMPRSS-2 in hospitalized COVID-19 patients. We also checked how this level might reflect the severity of the disease. We found that critically ill COVID-19 patients (the ones in ICU) had higher levels of TMPRSS-2 and aromatase, and lower testosterone levels. When we used these hormone levels to predict death in hospitalized COVID-19 patients, higher levels of TMPRSS-2 and aromatase were linked to a lower chance of survival.

Health care costs among patients with relapsed/refractory multiple myeloma treated with ixazomib or daratumumab in combination with lenalidomide and dexamethasone in the United States.

Available treatments for relapsed/refractory multiple myeloma (RRMM) include multiclass triplet regimens such as lenalidomide and dexamethasone (Rd backbone) plus ixazomib (proteasome inhibitor [PI]; I) or daratumumab (monoclonal antibody; D). Although prior real-world studies compared PI-Rd triplets, this research extends those findings by comparing health care costs of a PI-based and a monoclonal antibody-based triplet, IRd and DRd, in patients with RRMM in the United States. To describe and compare all-cause and MM-related health care costs in patients with RRMM treated with IRd vs DRd. This retrospective longitudinal study used fully adjudicated US claims data from IQVIA PharMetrics Plus (January 1, 2015, to September 30, 2020) and included adult patients who initiated IRd or DRd as second line of therapy (LOT) or later. Index date was the treatment initiation date for each LOT; baseline was 6 months pre-index. MM-related and all-cause costs per patient per month were assessed during follow-up (2020 US dollars). For MM-related costs, treatment administration costs were excluded from outpatient (OP) costs and instead summed with pharmacy costs. Costs were compared using 2-part models and generalized linear models. Inverse probability of treatment weighting was used to adjust for imbalances in baseline confounders across treatment groups. A total of 265 patients who initiated IRd or DRd were included in this analysis, contributing to 276 distinct LOTs (IRd: n = 153; DRd: n = 123). Baseline characteristics were similar between IRd and DRd cohorts after applying inverse probability of treatment weighting. Weighted (ie, adjusted) mean monthly MM-related total costs were significantly lower for the IRd cohort compared with the DRd cohort (-$8,141; P < 0.001). Total MM-related medical (-$4,764; P < 0.001), OP (-$3,152; P < 0.001), and pharmacy and OP treatment administration costs (-$3,563; P = 0.017) were also significantly lower for the IRd cohort. When comparing patients with MM in the IQVIA PharMetrics Plus commercial insurance database, which reflects the payer perspective, significant cost savings were observed for patients treated with IRd vs DRd owing to lower OP and pharmacy costs. These findings may help inform real-world treatment and reimbursement decisions for patients with RRMM.

Outcome of the novel description of arterial position changes after major liver resections: retrospective study.

After major liver resections, anatomical shifts due to liver parenchymal hypertrophy and organ displacement can happen. The aim of this study was to evaluate the impact of these anatomical changes on the main abdominal arteries (coeliac trunk and superior mesenteric artery) and on patient outcomes. All patients who underwent major liver resections (between January 2010 and July 2021) and who underwent preoperative and postoperative arterial-phase contrast-enhanced abdominal CT imaging were studied. Observed arterial position changes were classified into three groups: no position changes; class I position changes (vessel displacement with or without kinking with a vessel angle greater than 105°); and class II position changes (kinking less than or equal to 105°). The Mann-Whitney test and the Kruskal-Wallis test were used to compare continuous variables and the chi-squared test and Fisher's exact test were used to compare categorical variables. Univariable and multivariable logistic regression analyses were used to identify the risk factors for morbidity and mortality. A total of 265 patients (149 men and median age of 59 years) were enrolled. Arterial position changes were detected in a total of 145 patients (54.7%) (99 patients (37%) with class I position changes and 46 patients (18%) with class II position changes) and were observed more often after extended resection and right-sided resection (P < 0.001). Major complications were seen in 94 patients (35%) and the rate of mortality was 15% (40 patients died). Post-hepatectomy liver failure (P = 0.030), major complications (P < 0.001), and mortality (P = 0.004) occurred more frequently in patients with class II position changes. In multivariable analysis, arterial position change was an independent risk factor for post-hepatectomy liver failure (OR 2.86 (95% c.i. 1.06 to 7.72); P = 0.038), major complications (OR 2.10 (95% c.i. 1.12 to 3.93); P = 0.020), and mortality (OR 2.39 (95% c.i. 1.03 to 5.56); P = 0.042). Arterial position changes post-hepatectomy are observed in the majority of patients and are significantly related to postoperative morbidities and mortality.

Abstract P442: Impact of arterial stiffness on the blood pressure lowering effect of the dual endothelin antagonist aprocitentan in patients with resistant hypertension

Background: The phase-3 PRECISION study demonstrated the efficacy of aprocitentan to lower both office and ambulatory blood pressure (BP) in patients with resistant hypertension. Increased arterial stiffness has been associated with less favorable responses to pharmacologic BP lowering therapies. In this post-hoc analysis, we investigated the impact of arterial stiffness, assessed by the ambulatory arterial stiffness index (AASI), on the BP lowering effect of aprocitentan. Methods: The study included a 4-week double blind period (aprocitentan 12.5 mg, 25 mg, or placebo) and a 32-week single blind period (aprocitentan 25 mg). A total of 730 patients with resistant hypertension were randomized and 633 had available ambulatory BP monitoring (ABPM) results at baseline. The AASI was calculated from ABPM data as 1 minus the regression slope of diastolic on systolic BP. The patient population was dichotomized into two groups according to the baseline median AASI. Results: Patients with higher baseline AASI (≥0.54) tended to be older (63±11 versus 60±10) and to have a higher 24-hour ambulatory systolic BP (140±14 versus 135±14 mmHg) than patients with lower AASI (&lt;0.54). These patients with higher baseline AASI were also more likely to have chronic kidney disease stage 3-4 corresponding to an estimated glomerular filtration rate in the 15 to 60 mL/min/1.73 m 2 range (27% versus 18%). The BP lowering effect of aprocitentan at Week 4 was similar for both the patients with stiffer vasculature who have a higher baseline AASI (≥0.54) and for those with a lower AASI (&lt;0.54) (Table 1). No relevant change in AASI was reported with aprocitentan treatment at Week 4 (end of the double-blind period) or Week 36 (end of the single-blind period). Conclusion: Aprocitentan is an effective BP lowering therapy across the arterial stiffness continuum observed in patients with resistant hypertension. Longer observation times are needed to fully assess the impact of treatment on this structural and functional parameter.

Sex as a Predictor of Outcomes for Symptomatic Carotid Stenosis: A Comparative Analysis between CAS and CEA.

Reporting gender-related outcomes for symptomatic carotid lesion revascularization after both endarterectomy (CEA) and carotid artery stenting (CAS) procedures in an unselected group of patients treated by Italian Vascular Specialists. A retrospective study was conducted on patients presenting with recently symptomatic carotid stenosis treated by CAS and by CEA. The primary endpoint was the 30 days any stroke occurrence rate; secondary endpoints were technical success, occurrence of transient ischemic attack (TIA), acute myocardial infarction (AMI) and death. Demographic, clinical and procedural data were all noted in order to identify the outcome's determining factor. A total of 265 patients (193 males and 72 females) were enrolled, and of these 134 (50.5%) underwent CEA and 131 CAS (49.5%). At 30 days, the overall new stroke rate was 3.4% (one fatal), and no TIA, AMI or deaths were observed. Among strokes, seven major and two minor strokes were reported, with six after CEA and three after CAS (p = 0.32; OR: 2; CI95%: 0.48-8.17). The timing of revascularization has been found to be slightly associated with new stroke occurrence: seven out nine strokes were observed in patients treated within 14 days from symptom onset (5.5% vs. 1.4%; p = 0.08, OR: 3.8, CI95%: 0.77-18.56). Lastly, female patients presented a significantly higher risk of post-operative stroke compared to male patients: 6.9% vs. 2.1% (p: 0.05; OR: 3.52; CI95%: 0.91-13.52). Our experience seems to suggest that both CEA and CAS provide safe and effective results in treating patients presenting with symptomatic carotid stenosis. Regardless of the type of revascularization, female sex is an independent risk factor for stroke recurrence after treatment.

Machine Learning-Based Prediction of 1-Year Survival Using Subjective and Objective Parameters in Patients With Cancer.

Palliative care is recommended for patients with cancer with a life expectancy of <12 months. Machine learning (ML) techniques can help in predicting survival outcomes among patients with cancer and may help distinguish who benefits the most from palliative care support. We aim to explore the importance of several objective and subjective self-reported variables. Subjective variables were collected through electronic psycho-oncologic and palliative care self-assessment screenings. We used these variables to predict 1-year mortality. Between April 1, 2020, and March 31, 2021, a total of 265 patients with advanced cancer completed a patient-reported outcome tool. We documented objective and subjective variables collected from electronic health records, self-reported subjective variables, and all clinical variables combined. We used logistic regression (LR), 20-fold cross-validation, decision trees, and random forests to predict 1-year mortality. We analyzed the receiver operating characteristic (ROC) curve-AUC, the precision-recall curve-AUC (PR-AUC)-and the feature importance of the ML models. The performance of clinical nonpatient variables in predictions (LR reaches 0.81 [ROC-AUC] and 0.72 [F1 score]) are much more predictive than that of subjective patient-reported variables (LR reaches 0.55 [ROC-AUC] and 0.52 [F1 score]). The results show that objective variables used in this study are much more predictive than subjective patient-reported variables, which measure subjective burden. These findings indicate that subjective burden cannot be reliably used to predict survival. Further research is needed to clarify the role of self-reported patient burden and mortality prediction using ML.

Association between lipoprotein (a) and risk of atherosclerotic cardiovascular disease events among maintenance hemodialysis patients in Beijing, China: a single-center, retrospective study

BackgroundSerum lipoprotein(a) [Lp(a)] is an independent risk factor for atherosclerotic cardiovascular disease (ASCVD) in the general population, its association with ASCVD incidence in Chinese maintenance hemodialysis (MHD) patients remains unclear. We aimed to evaluate the relationship between Lp(a) levels and ASCVD incidence among MHD patients in Beijing, China.MethodsThis retrospective, observational cohort study included MHD patients at Beijing Tongren Hospital from January 1, 2013 to December 1, 2020, and followed until December 1,2023. The primary outcome was ASCVD occurrence. Kaplan-Meier survival analysis was used to evaluate ASCVD-free survival in MHD patients, with stratification based on Lp(a) levels. Cox regression analyses were conducted to assess the association between Lp(a) levels and the occurrence of ASCVD.ResultsA total of 265 patients were enrolled in the study. The median follow-up period were 71 months.78 (29.4%) participants experienced ASCVD events, and 118 (47%) patients died, with 58 (49.1%) deaths attributed to ASCVD. Spearman rank correlation analyses revealed positive correlations between serum Lp(a) levels and LDL-c levels, and negative correlations with hemoglobin, triglyceride, serum iron, serum creatinine, and albumin levels. Multivariate Cox regression analysis showed that Lp(a) levels ≥ 30 mg/L, increased age, decreased serum albumin levels, and a history of diabetes mellitus were significantly associated with ASCVD incidence.ConclusionsThis study demonstrated an independent and positive association between serum Lp(a) levels and the risk of ASCVD in MHD patients, suggesting that serum Lp(a) could potentially serve as a clinical biomarker for estimating ASCVD risk in this population.

Vascular Clips for Preventing Lymphocele and Symptomatic Lymphocele in Patients With Gynecologic Malignancies After Laparoscopic Pelvic Lymphadenectomy

Study ObjectiveTo evaluate the effectiveness of using vascular clips to seal targeted lymphatics in gynecological malignancies for the prevention of postoperative pelvic lymphocele and symptomatic lymphocele after laparoscopic pelvic lymphadenectomy. DesignRetrospective analysis. SettingSingle-center academic hospital. PatientsIn total, 217 patients with gynecological malignancies were included. InterventionsPatients were classified into two groups: group 1 (vascular clips were used to seal the targeted lymphatics) and group 2 (electrothermal instruments were used to seal the targeted lymphatics). The patients were followed up 4–6 weeks after surgery to evaluate the incidence of lymphoceles by ultrasound or CT. Symptomatic lymphoceles are defined as those that cause infection, deep vein thrombosis with or without swelling of the extremities, edema (swelling) of the extremities or perineum, hydronephrosis, and/or moderate to severe pain. Measurements and Main ResultsOne hundred and thirteen patients were enrolled in group 1, and 104 patients were enrolled in group 2. Lymphoceles were observed in 46 (21.2%) patients. Fewer lymphoceles occurred in group 1 than in group 2 (8 [7.1%] vs. 38 [36.5%], p <.001). The percentage of significantly sized lymphoceles was lower in group 1 than that in group 2 (4 [3.5%] vs. 30 [28.8%], p <.001]. Symptomatic lymphoceles occurred in 18 patients (8.3%), and only one (1.0%) occurred in group 1, while 17 (16.3%) occurred in group 2 (p <.001). A multivariate analysis revealed that vascular clips were the only independent factor for preventing lymphocele (OR = 7.65, 95% CI = [3.30–17.13], p <.001) and symptomatic lymphocele (OR = 22.03, 95% CI = [2.84–170.63], p = .003). ConclusionThe results indicate that the use of vascular clips may be useful for the prevention of the development of lymphocele and symptomatic lymphocele secondary to pelvic lymphadenectomy performed via laparoscopy.

Analysis of Prognostic Factors in Non-Traumatic and Non-Diabetic Retinopathy Patients Undergoing Vitrectomy.

Vitrectomy is one of the crucial therapeutic interventions for non-traumatic and non-diabetic retinal diseases. However, the prognosis of patients undergoing this procedure and the factors affecting prognosis remain to be clarified. The aim of this study was to analyze the prognostic factors of non-traumatic and non-diabetic retinopathy complicated by vitreous hemorrhage. A retrospective study was conducted on 352 patients, including 152 (43.18%) females, who underwent vitrectomy in our hospital from March 2018 to December 2022, divided into Group A (postoperative complications) and Group B (no complications) according to whether complications occurred during postoperative follow-up. General and clinical data of the two groups were collected and compared. Binary logistic regression was used to analyze the main factors affecting prognosis. All patients were followed up for 12 months. A total of 87 patients had postoperative complications, accounting for 24.72% (87/352), and were classified as Group A. A total of 265 patients who had no postoperative complications, accounting for 75.28% (265/352), were classified as Group B. There were significant differences in preoperative visual acuity, time of surgical intervention, preoperative fundus condition, stage of retinopathy, preoperative intraocular pressure and age between the two groups (p < 0.05), and these indices were identified as independent risk factors affecting the prognosis of patients (odds ratio >1). Preoperative visual acuity, time of surgical intervention, preoperative fundus condition, stage of retinopathy, preoperative intraocular pressure and age are all factors affecting the prognosis of patients with non-traumatic and non-diabetic retinopathy while undergoing vitrectomy. Personalized care is required to improve the surgical outcome for these patients.

Comparison of Interstitial Lung Disease Between Antineutrophil Cytoplasmic Antibodies Positive and Negative Patients: A Retrospective Cohort Study.

Positive antineutrophil cytoplasmic antibodies (ANCAs) may occur in the setting of interstitial lung disease (ILD), with or without ANCA-associated vasculitis (AAV). We aim to compare the characteristics and clinical course of patients with ILD and positive ANCA (ANCA-ILD) to those with negative ANCA. We performed a single-center retrospective cohort study from 2018 to 2021. All patients with ILD and ANCA testing were included. Patient characteristics (symptoms, dyspnea scale, and systemic AAV), test results (pulmonary high-resolution computed tomography and pulmonary function tests), and adverse events were collected from electronic medical records. Descriptive statistics and the Fisher exact test were used to compare the outcomes of patients with ANCA-ILD to those with ILD and negative ANCA. A total of 265 patients with ILD were included. The mean follow-up duration was 69.3 months, 26 patients (9.8%) were ANCA positive, and 69.2% of those with ANCA-ILD had another autoantibody. AAV occurred in 17 patients (65.4%) with ANCA-ILD. In 29.4% of patients, AAV developed following ILD diagnosis. Usual interstitial pneumonia was the most common radiologic pattern in patients with ANCA-ILD. There was no association between ANCA status and the evolution of dyspnea,diffusing capacity of the lungs for carbon monoxide, and lung imaging. Forced vital capacity improved over time in 42% of patients with ANCA-ILD and in 17% of patients with negative ANCA (P = 0.006). Hospitalization occurred in 46.2% of patients with ANCA-ILD and in 21.8% of patients with negative ANCA (P = 0.006). Both groups had similar mortality rates. Routine ANCA testing should be considered in patients with ILD. Patients with ANCA-ILD are at risk for AAV. More research is required to better understand and manage patients with ANCA-ILD.

An Observational Study of the Physical and Biochemical Complications and Socioeconomic Status of Type 1 Diabetic Patients in West Bengal, India: A 25-year Follow-up Report of 224 Patients.

Limited information is available on the total profile of type 1 diabetes mellitus patients in India. The present study has been undertaken, therefore, in search of socioeconomic status, glycaemic status and the state of complications of the type 1 diabetics attending the diabetic clinic run by Calcutta Diabetes and Endocrine Foundation (CDEF), Kolkata. (1) To obtain the glycemic, socioeconomic, and complications status of type 1 diabetic patients; (2) to see any change of the abovementioned parameters in this follow-up period of 25 years; (3) to take necessary action to improve the quality of care and the health condition of the type 1 diabetics attending the clinic. A longitudinal observational study. A total of 265 patients were recruited for the study, having been diagnosed or seen within 1 year of diagnosis of type 1 diabetes at the Diabetic Clinic of CDEF. A total of 41 patients were excluded from the study for different reasons, and 224 patients were finally selected. These 224 patients were classified into five separate cohorts according to their first attendance in the diabetes clinic: 1996-2000 (I), 2001-2005 (II), 2006-2010 (III), 2011-2015 (IV), and 2016-2020 (V). Baseline and socioeconomic (based on education and occupational status) data was obtained at the first visit, and mean biochemical parameters were taken from multiple visits. Complications and mortality rates were calculated against the duration of the disease at the end of the study. Gradual improvement of glycemic status was noted when groups I and V were compared. Delayed development of complications and comparatively long life were also observed. Several methods of improvement of clinical disease management, including continuous diabetes education with proper training, can improve diabetes care, leading to delays in the development of diabetic complications and ensuring longer as well as healthier life in type 1 diabetes. The development of socioeconomic status might have played some role.

Enhancing quality of life in severe post-COVID-19 survivors through multidisciplinary care.

COVID-19 survivors who were hospitalised continue to experience long-term multisystemic sequelae and symptoms, impacting their health-related quality of life (HRQoL). The complexity of post-COVID-19 conditions underscores the importance of adopting a multidisciplinary, patient-centric approach to ensure ongoing care. This study aims to assess HRQoL and post-COVID symptoms in a cohort of severe COVID-19 survivors depending on their participation in a multidisciplinary programme. This prospective study was conducted in a post-COVID clinic staffed by a multidisciplinary team (physical rehabilitator, nutritionist, psychologist, including experts in pulmonary rehabilitation, nutrition, psychology and others). Subjects over 18 years old who were hospitalised due to severe COVID-19 during the acute phase and had attended the post-COVID clinic within the first 3 months following discharge were included. Subjects who were unable or unwilling to provide informed consent to participate in the protocol were excluded. Linear mixed-effect models were employed to examine changes in 12-Item Short-Form Health Survey (SF-12) component scores. The resolution of post-COVID symptom clusters was compared using the Cox model. A total of 730 patients were included, with a mean±sd age of 55.78±15.43 years; 60.55% were male and 90.62% required mechanical ventilation during hospitalisation. Programme attendants demonstrated improved SF-12 physical and mental component scores at 3 and 12 months. A reduction in the prevalence of post-COVID symptoms was observed in both groups, with greater reductions in those attending the programme. Our study showed that patients enrolled on the multidisciplinary programme experienced improvements in fatigue, musculoskeletal, gastrointestinal, neuropsychiatric and respiratory symptoms, along with enhanced SF-12 mental and physical component scores.

Nomogram for the prediction of infected pancreatic necrosis in moderately severe and severe acute pancreatitis.

As a serious complication of moderately severe acute pancreatitis (MSAP) and severe acute pancreatitis (SAP), infected pancreatic necrosis (IPN) can lead to a prolonged course of interventional therapy. Most predictive models designed to identify such patients are complex or lack validation. The aim of this study was to develop a predictive model for the early detection of IPN in MSAP and SAP. A total of 594 patients with MSAP or SAP were included in the study. To reduce dimensionality, least absolute shrinkage and selection operator regression analysis was used to screen potential predictive variables, a nomogram was then constructed using logistic regression analysis. The receiver operating characteristic (ROC) curve, calibration curve, and decision curve analysis (DCA) were used to evaluate the discrimination, accuracy, and clinical efficacy of the model. External data were also obtained to further validate the constructed model. There were 476, 118, and 82 patients in the training, internal validation, and external validation cohorts, respectively. Platelet count, hematocrit, albumin/globulin, severity of acute pancreatitis, and modified computed tomography severity index score were independent factors for predicting IPN in MSAP and SAP. The area under the ROC curves were 0.923, 0.940, and 0.817, respectively, in the three groups. There was a good consistency between the actual probabilities and the predicted probabilities. DCA revealed excellent clinical utility. The constructed nomogram is a simple and feasible model that has good clinical predictive value and efficacy in clinical decision-making for IPN in MSAP and SAP.

Multiparametric MRI-based intratumoral and peritumoral radiomics for predicting the pathological differentiation of hepatocellular carcinoma

PurposeTo explore the predictive potential of intratumoral and multiregion peritumoral radiomics features extracted from multiparametric MRI for predicting pathological differentiation in hepatocellular carcinoma (HCC) patients.MethodsA total of 265 patients with 277 HCCs (training cohort n = 193, validation cohort n = 84) who underwent preoperative MRI were retrospectively analyzed. The risk factors identified through stepwise regression analysis were utilized to construct a clinical model. Radiomics models based on MRI (arterial phase, portal venous phase, delayed phase) across various regions (entire tumor, Peri_5mm, Peri_10mm, Peri_20mm) were developed using the LASSO approach. The features obtained from the intratumoral region and the optimal peritumoral region were combined to design the IntraPeri fusion model. Model performance was assessed using the area under the curve (AUC).ResultsLarger size, non-smooth margins, and mosaic architecture were risk factors for poorly differentiated HCC (pHCC). The clinical model achieved AUCs of 0.77 and 0.73 in the training and validation cohorts, respectively, while the intratumoral model achieved corresponding AUC values of 0.92 and 0.82. The Peri_10mm model demonstrated superior performance to the Peri_5mm and Peri_20mm models, with AUC values of 0.87 vs. 0.84 vs. 0.73 in the training cohort and 0.80 vs. 0.77 vs. 0.68 in the validation cohort, respectively. The IntraPeri model exhibited remarkable AUC values of 0.95 and 0.86 in predicting pHCC in the training and validation cohorts, respectively.ConclusionsOur study highlights the potential of a multiparametric MRI-based radiomic model that integrates intratumoral and peritumoral features as a tool for predicting HCC differentiation.Critical relevance statementBoth clinical and multiparametric MRI-based radiomic models, particularly the intratumoral radiomic model, are non-invasive tools for predicting HCC differentiation. Importantly, the IntraPeri fusion model exhibited remarkable predictiveness for individualized HCC differentiation.Key points• Both the intratumoral radiomics model and clinical features were useful for predicting HCC differentiation.• The Peri_10mm radiomics model demonstrated better diagnostic ability than other peritumoral region-based models.• The IntraPeri radiomics fusion model outperformed the other models for predicting HCC differentiation.Graphical

Long-Term Outcomes of Robotic Versus Laparoscopic Total Mesorectal Excisions: A Propensity-Score Matched Cohort study of 5-year survival outcomes.

To compare long-term outcomes between laparoscopic and robotic total mesorectal excisions (TMEs) for rectal cancer in a tertiary center. Laparoscopic rectal cancer surgery has comparable long-term outcomes to the open approach, with several advantages in short-term outcomes. However, it has significant technical limitations, which the robotic approach aims to overcome. We included patients undergoing laparoscopic and robotic TME surgery between 2013 and 2021. The groups were compared after propensity-score matching. The primary outcome was 5-year overall survival (OS). Secondary outcomes were local recurrence (LR), distant recurrence (DR), disease-free survival (DFS), and short-term surgical and patient-related outcomes. A total of 594 patients were included, and after propensity-score matching 215 patients remained in each group. There was a significant difference in 5-year OS (72.4% for laparoscopy vs 81.7% for robotic, P = 0.029), but no difference in 5-year LR (4.7% vs 5.2%, P = 0.850), DR (16.9% vs 13.5%, P = 0.390), or DFS (63.9% vs 74.4%, P = 0.086). The robotic group had significantly less conversion (3.7% vs 0.5%, P = 0.046), shorter length of stay [7.0 (6.0-13.0) vs 6.0 (4.0-8.0), P < 0.001), and less postoperative complications (63.5% vs 50.7%, P = 0.010). This study shows a correlation between higher 5-year OS and comparable long-term oncological outcomes for robotic TME surgery compared to the laparoscopic approach. Furthermore, lower conversion rates, a shorter length of stay, and a less minor postoperative complications were observed. Robotic rectal cancer surgery is a safe and favorable alternative to the traditional approaches.

Association between haemoglobin, albumin, lymphocytes, and platelets and mortality in patients with heart failure.

The combination of haemoglobin, albumin, lymphocytes, and platelets (HALP) is a new metric used to assess patient prognosis in many diseases. This study aimed to assess the relationship between HALP and short- and long-term mortality in patients with heart failure. This retrospective cohort study included adult patients with heart failure who were hospitalized between 2019 and 2021. The primary outcomes were 1-month mortality and 1-year mortality. The multivariable logistic regression analysis was used to evaluate the association between HALP and the risk of mortality. Stratified analyses were conducted based on New York Heart Association functional classification (NYHA) stage (II/III, IV) and left ventricular ejection fraction (LVEF, <50%, ≥50%). The area under the receiver operating characteristic curve (AUC) was used to evaluate the ability of HALP, prognostic nutritional index (PNI), C-reactive protein (CRP), and the Meta-Analysis Global Group in Chronic Heart Failure (MAGGIC-HF) risk score in predicting mortality in patients with heart failure. A total of 730 patients with heart failure were included, of whom 61 (8.36%) died within 1month and 77 (10.55%) died within 1year. High HALP scores were associated with a reduced risk of 1-month mortality (odds ratio (OR)=0.978, 95% confidence interval (CI): 0.963-0.992, P=0.003) and 1-year mortality (OR=0.987, 95% CI: 0.977-0.997, P=0.009) in patients with heart failure. In patients with different NYHA stages or LVEF levels, high HALP scores were correlated with a reduced risk of 1-year mortality in patients with NYHA stage II/III (OR=0.978, 95% CI: 0.957-1.000, P=0.045) or LVEF ≥50% (OR=0.970, 95% CI: 0.945-0.996, P=0.024). The AUC for HALP, PNI, CRP, and MAGGIC-HF to predict 1-year mortality in patients with heart failure were 0.677 (95% CI: 0.619-0.735), 0.666 (95% CI: 0.608-0.723), 0.638 (95% CI: 0.572-0.704), and 0.654 (95% CI: 0.591-0.717), respectively. HALP may be a potential marker for predicting mortality in patients with heart failure. Further exploration based on HALP may yield better clinical predictors of prognosis in patients with heart failure.

Prevalence and predictors of persistent cognitive and psychological symptoms in non-hospitalized post-COVID-19 patients seeking care at an outpatient post-COVID-19 clinic.

There is still much uncertainty about why some people develop persistent cognitive and mental health problems after SARS-CoV-2 infection and require additional care while others do not. In this study, we investigated the cognitive and psychological outcomes of non-hospitalized post-COVID-19 patients referred to an outpatient post-COVID-19 clinic for persistent symptoms more than 3 months after infection. Additionally, we aimed to explore the influence of demographic, physical, and personal factors on these outcomes. This cross-sectional study was conducted at an outpatient post-COVID-19 clinic located at a prominent clinical teaching hospital in the Netherlands. Participants included non-hospitalized patients referred between 2020 and 2022, more than 3 months after SARS-CoV-2 infection, experiencing persistent symptoms. Main outcome measures included levels of anxiety and depression (Hospital Anxiety and Depression Scale), post-traumatic stress symptoms (PTSS) (Post-traumatic Stress Symptoms Checklist 14), and cognitive symptoms (Checklist for Cognitive and Emotional Consequences). Data analysis employed Spearman correlation and hierarchical multiple regression analyses. A total of 265 patients (61% female; mean age of 51.7 ± 13.7 years) were included in the study, with an average of 7.6 ± 4.5 months following SARS-CoV-2 infection. Among them, 104 patients (40%) reported high levels of anxiety, 111 patients (43%) showed high levels depressive symptoms, and 71 patients (31%) demonstrated high levels of PTSS. Additionally, 200 patients (79%) reported experiencing more than 2 cognitive symptoms. Bivariate analyses indicated associations between psychiatric history and increased cognitive and psychological symptoms. Multivariate analyses revealed positive associations between physical symptoms and cognitive and psychological symptoms, and catastrophizing thoughts were associated with higher anxiety levels (β = 0.217, p < 0.001). Conversely, positive refocusing was associated with lower depressive symptoms (β = -0.325, p < 0.001), PTSS (β = -0.290, p < 0.001), and cognitive symptoms (β = -0.220, p < 0.001). Among non-hospitalized COVID-19 patients seeking care for persistent symptoms, approximately one-third reported high levels of psychological symptoms, and more than three-quarter experienced cognitive symptoms. Physical symptoms, psychiatric history, and a tendency to catastrophize were identified as potential risk factors for persistent psychological and cognitive symptoms. Conversely, positive refocusing demonstrated a protective effect. These findings contribute to the understanding of long-term COVID-19 outcomes and emphasize the importance of integrating a biopsychosocial perspective into treatment approaches.
