Implementing the Global Leadership Initiative on Malnutrition (GLIM) criteria in Crohn's disease: prevalence of malnutrition and association with clinical outcomes

Background & AimsLimited data exist regarding the implementation of the Global Leadership Initiative on Malnutrition (GLIM) criteria for diagnosing malnutrition in Crohn’s disease (CD), and its association with CD prognosis. In the present study eighteen GLIM combinations and a combined one were implemented to identify differences in the prevalence of malnutrition and to investigate potential associations with clinical outcomes at 6 months. MethodsDifferent methodologies to diagnose malnutrition were used at baseline, namely the Subjective Global Assessment (SGA), eighteen different combinations of phenotypic and etiologic GLIM criteria and a combined version based on all GLIM combinations (GLIMcv) to test differences in the estimated prevalence and outcomes’ prognosis. At 6 months, data for clinical outcomes were collected (i.e. hospitalization, antibiotics use, intensification/change of biologic agent, initiation of biologic agent/corticosteroids, surgery, disease activity), and an overall adverse clinical outcome index was created. Results250 people with CD (54.8% males, mean age 41.2±14.1 years, 37.2% with active disease) were enrolled. Prevalence of malnutrition based on SGA and GLIMcv was 23% and 52%, respectively, and 5.8-63% based on different GLIM combinations. Malnutrition diagnosed with GLIMcv was associated with an increased likelihood of intensification/change of biologic agent [Odds ratio (OR): 1.82, 95% Confidence interval (CI): 1.00-3.42, p=0.05] and an overall adverse clinical outcome (OR: 2.18, 95% CI: 1.23-3.87, p=0.008) at 6 months, after adjustment for age, sex, disease location and duration. Malnutrition diagnosed through SGA was not associated with clinical outcomes at 6 months. ConclusionsBased on GLIMcv, half of the sample was diagnosed with malnutrition. Malnutrition significantly increased the likelihood of uncontrolled disease requiring treatment upgrading and leading to an overall adverse clinical outcome short term.

Lower urinary tract symptoms (LUTS) as a clinical feature of lumbar spinal stenosis (LSS): a prospective study with lumbar spine morphometry analysis

<p><strong>Aim</strong> To investigate clinical and morphometric characteristics of patients with lower urinary tract symptoms (LUTS) due to lumbar spinal stenosis (LSS).<br /><strong>Methods</strong> This study evaluated LSS patients using clinical assessments of motor, sensory, bladder, and bowel functions, and functional disability scores from the Oswestry Disability Index (ODI) and Swiss Spinal Stenosis Questionnaire (SSSQ). Morphometric analysis included MRI measurements of the anteroposterior diameter of the intervertebral disc and dural sac, and the modified Torg-Pavlov ratio (mTPR), with follow-up re-evaluations at 6 months.<br /><strong>Results</strong> Of 159 patients, 49 (30.8%) had LUTS and 110 (69.2%) were in the control group. LUTS patients had a significantly higher prevalence of neurogenic claudication (100% vs. 47.3%; p<0.001), lower back pain (93.9% vs. 77.3%; p=0.011), and lower extremity pain (57.1% vs. 34.5%; p=0.008). The LUTS group also had higher ODI (54.0 vs. 50.0; p=0.019) and SSSQ score (44.0 vs. 34.0; p<0.001). Morphometric analysis showed significantly lower mTPR in LUTS patients (median 0.31 vs. 0.45; p<0.001), with an AUC of 0.704 (95%CI 0.627-0.774). mTPR≤0.31 predicted surgical revision within 6 months (OR:3.4, CI: 1.2-9.8), motor deficiency (OR:2.1, 95%CI: 1.4-5.2), and persistent LUTS post-surgery (OR:4.5, 95%CI: 1.1-18.9). mTPR≤0.34 was associated with worse follow-up outcome, including increased ODI (β:3.2; 95%CI: 1.1-5.3; p=0.004) and SSSQ score (β:4.8; 95%CI:2.1-7.5).<br /><strong>Conclusion</strong> LUTS patients with LSS exhibit more severe symptoms and poorer outcome, with mTPR≤0.34 being a predictor of adverse clinical outcome and the need for surgical revision within 6 months.</p>

Right ventricular global longitudinal strain by cardiac magnetic resonance feature tracking is associated with outcome in patients with a systemic right ventricle

Abstract Introduction It is well known, that patients with a systemic (sub-aortic) right ventricle (sRV) for congenitally-corrected transposition of the great arteries (TGA) or with complete TGA after atrial switch operation are more threatened to develop RV dysfunction, relevant supra- and ventricular tachycardia and have a reduced life expectancy. While the randomized, placebo-controlled, double-blinded, multi-centre SERVE trial to investigate the effect of phosphodiesterase-5 inhibitor tadalafil in sRV patients showed negative results on the primary end-point RV endsystolic volume (RVESV), aim of this sub-analysis was to evaluate RV global longitudinal strain (GLS), a more sensitive measure of RV function, by cardiac magnetic resonance (CMR) feature tracking (FT) over time, for treatment effect and to investigate whether RV GLS predicts clinical outcome in sRV patients. Methods CMR volumetric RV and FT parameters were analysed (blinded for patient and assessment time and treatment) at baseline and compared to follow-up (FU) after 3 years, or after 1 year in case of withdrawal of the study drug. FT was performed using appropriate software. Treatment effect was analysed using ANCOVA with baseline values and FU-time as covariates. Values of > 4th quartile of RV GLS were used as cut-off for Kaplan-Meier analysis on the primary outcome, defined as a composite of all-cause death, clinically relevant arrhythmias and hospitalisation for heart failure. Results CMR exams were available for 78 patients at baseline (40±11 years, 33% females) and for 71 patients at FU. No treatment effect of tadalafil compared to the placebo was discovered for RV GLS (p=0.26), RVESVi (p=0.63) and RV ejection fraction (RVEF, p=0.6). Over a 3 years FU-time, RV GLS mildly increased (p=0.0023, figure 1). During FU, 14 patients experienced a clinical outcome: 1 death, 4 hospitalisations for heart failure, and 12 clinically relevant arrhythmic events. An RV GLS > -13.4% was associated with adverse clinical outcome (p=0.003, figure 2). Conclusion In patients with a systemic RV, treatment with Tadalafil had no effect on CMR-derived RV global longitudinal strain compared to placebo. RV GLS changed significantly over the 3 years FU-time. A RV GLS value of > -13.4% is associated with adverse clinical outcome in these patients.Figure 1Figure 2

The value of magnetic resonance imaging in congenital cytomegalovirus infection: a systematic review.

Congenital cytomegalovirus (cCMV) infection can lead to severe neurodevelopmental and hearing impairments. Imaging techniques can be used both pre- and postnatally to assess early signs of infection. The objective was to provide a systematic review of current literature regarding magnetic resonance imaging (MRI) and its value to predict clinical outcome in children with cCMV. PubMed, Embase, and Web of Science were searched for studies investigating MRI in cCMV between 2016-2024. Risk of bias was assessed using Newcastle-Ottawa quality assessment scales. Descriptive synthesis was performed. Twenty studies were included. MRI detected brain abnormalities in 5.0-53.0% of infected patients prenatally and 26.9-69.0% postnatally. The three most frequently detected abnormalities included white matter lesions, subependymal cysts, and ventricular dilatation. Symptoms at birth, first trimester seroconversion, and high viral load were associated with abnormal MRI; however, brain abnormalities were still found in 33-37% of clinically asymptomatic patients. Prenatal MRI had a negative predictive value of 94-100% and a positive predictive value of 12-60% for predicting adverse clinical outcome. Five in six studies found an association between MRI abnormalities and neurodevelopmental impairments, five in eight with (congenital) hearing loss. MRI detected additional abnormalities in 5.6-19.4% of children with normal ultrasound.In conclusion,MRI can detect a wide range of brain abnormalities, both pre- and postnatally, in symptomatic and asymptomatic patients. MRI can be a helpful tool in the prediction of clinical impairments and seems complementary to ultrasound. Therefore, both fetal and neonatal MRI should be considered in the standard work-up of all cCMV-infected children.

Risks factors of adverse clinical outcomes in asymptomatic mitral regurgitation patients with preserved ejection fraction: a systematic review and meta-analysis.

Indication for mitral valve (MV) surgery in asymptomatic mitral regurgitation (MR) patients with preserved ejection fraction (EF) remains unclear. This study aims to identify risk factors of adverse clinical outcomes in asymptomatic MR patients with preserved EF for early indication of MV surgery. 3 databases were systematically searched to include studies with asymptomatic MR patients with preserved EF. Risk factors of adverse clinical outcomes (composite outcome of MACE and MV surgery indication), mortality, and left ventricular dysfunction (LVD) are pooled with a meta-analysis of random effect model. A total of 39 observational studies with 9135 asymptomatic moderate to severe MR patients are included. We identified 21 statistically significant risk factors for adverse outcomes. Increased natriuretic peptide, presence of atrial fibrillation, LV GLS > 20%, LVEDD > 35mm, LVESD > 22mm, and LAVI > 55ml/mm2, ERO > 55mm2, and regurgitation volume > 60ml (HR 2.21, 2.07, 4.23, 2.98, 4.05, 1.84, 4.02, 3.30, respectively; p-value < 0.05; I2 0-87%) are associated with greater risk of adverse clinical outcome. Risk factors associated with postoperative LVD are the increase of LVEDD, LVESD, and RVSP. Risk factors associated with mortality are increasing STS score and LV GLS. Several clinical parameters and risk factors can be used to stratify asymptomatic MR patients with preserved ejection fraction who could benefit from early indication for MV surgery.

Association of circulating Z-polymer with adverse clinical outcomes and liver fibrosis in adults with alpha-1 antitrypsin deficiency.

Circulating polymerized mutant Z-alpha-1 antitrypsin (Z-polymer) constitutes a characteristic feature in alpha-1 antitrypsin deficiency (AATD), but there is limited knowledge about its association with adverse clinical outcomes and liver fibrosis. We explored this association using data from a large cohort of adults with AATD. A total of 836 (431 PiZZ, 405 PiMZ) adults with AATD and 312 controls (PiMM) from the European Alpha-1 Liver Cohort (2015-2020) were included. Time-to-event analyses were conducted for adults with the PiZZ genotype followed for adverse clinical outcomes (earliest occurrence of liver-related hospitalization, liver transplant or all-cause mortality). Cox proportional hazard models were used to describe the association between binary circulating Z-polymer levels and adverse clinical outcomes. Correlations between baseline circulating Z-polymer levels and baseline liver fibrosis (liver stiffness measurement [LSM] determined by transient elastography [FibroScan®]) were evaluated. The analyses were stratified by augmentation therapy status. Of 324 adults with the PiZZ genotype and longitudinal follow-up data, 28 reported adverse clinical outcomes. Higher baseline circulating Z-polymer levels were associated with an increased risk of adverse clinical outcomes in both crude (hazard ratio [95% confidence interval, CI], 2.88 [1.21, 6.87]) and age-adjusted (1.96 [0.78, 4.94]) analyses. In adults with the PiZZ genotype, circulating Z-polymer levels were weakly positively correlated with baseline LSM (Spearman's rho [95% CI]: 0.21 [0.11, 0.31]). Similar results were observed after stratification by augmentation therapy status. In adults with the PiZZ genotype, higher circulating Z-polymer levels were associated with a shorter time to adverse clinical outcome, and positively correlated with baseline LSM. Circulating Z-polymer levels may be a prognostic biomarker of clinically relevant disease in AATD.

Redo surgical aortic valve replacement for bioprosthetic structural valve deterioration.

To compare isolated primary bioprosthetic surgical aortic valve replacement (SAVR) with isolated redo surgical aortic valve replacement (rSAVR) due to structural valve deterioration (SVD). Clinical data of consecutive patients who underwent primary isolated SAVR and isolated rSAVR due to SVD between January 1, 2011, and December 31, 2022, at Leipzig Heart Center were retrospectively compared with regard to the primary outcome of all-cause mortality or stroke during hospitalization. Secondary outcomes of interest included myocardial infarction, re-exploration for bleeding, and permanent pacemaker implantation. A total of 2620 patients, 39.5% females, with a median EuroSCORE II of 1.7 (interquartile Range [IQR] 1.1; 2.7] were identified, of which rSAVR was performed in 174 patients (6.6%). Patients undergoing primary SAVR were older (69 versus 67 years of age, p = 0.001) and were less likely to have a history of prior stroke (0.9% versus 4.0%, p = 0.003). Although both all-cause death and death or stroke occurred less often following primary SAVR (0.5% versus 5.8%, and 2.2% versus 6.9%, respectively; p < 0.001), prior surgery was not associated with adverse clinical outcome in multivariable analysis. In a matched comparison of 322 patients, rates of death or stroke did not differ between groups (4.8% for both rSAVR and SAVR, p = 1.0). Although redo surgery for SVD is associated with increased rates of early mortality and stroke by univariate analysis, much of this increased risk can be accounted for by comorbidities. Patients undergoing rSAVR on an elective basis can expect an outcome similar to that of primary SAVR.

Curriculum Innovation: A Standardized Experiential Simulation Curriculum Equips Residents to Face the Challenges of Chief Year.

A chief resident's role incorporates administrative, academic, and interpersonal responsibilities essential to managing a successful residency program. However, rising chief residents receive little formal exposure to leadership training. To (1) define leadership styles; (2) understand the effect of cultural competence on leadership styles; (3) learn effective methods to advocate as the chief resident; (4) provide effective peer feedback; (5) provide effective supervisor feedback; (6) learn effective conflict management; (7) ensure psychological safety. We developed a 1-day curriculum combining didactics and simulation activities for our program's rising chief residents. Implementation of our curricular design included a morning session focusing on small groups and didactic-based lectures on specific topics pertinent to leadership, along with a debriefing of a psychometric evaluation tool administered before the curriculum day. The simulation activity consisted of 3 group objective structured clinical examination (G-OSCE) scenarios: (1) providing a struggling junior trainee with feedback; (2) debriefing an adverse clinical outcome as the team leader; (3) navigating a challenging situation with a supervising physician. Standardized participants were surveyed for specific objectives. Learners completed precurricular and postcurricular surveys on their familiarity and preparedness for their chief year. Comparison of preintervention (n = 16) and postintervention (n = 10) data shows improvements in familiarity with leadership models (p = 0.006), cultural competence in leadership (p = 0.027), and team organizational structure (p = 0.010) with notable improvement in report of advocating for the team to 100% of participants in the postcurricular survey. In addition, although not statistically significant, familiarity with specific strategies for feedback delivery improved (p = 0.053), as did learner comfort levels with feedback delivery (comparing 51% of learners were either very or somewhat comfortable precurriculum to 90% postcurriculum). This is further supported by standardized participant data after the G-OSCEs. Although familiarity with wellness resources did improve across learners (p = 0.421), learner-reported use of wellness resources was noted to be reduced after the curricular intervention and remains a result of further interest for exploration. A 1-day leadership development curriculum combining didactics and simulation is an effective means of preparing rising chief residents to succeed in their transition to this leadership role.

Hemin-induced reactive oxygen species triggers autophagy-dependent macrophage differentiation and pro-inflammatory responses in THP-1 cells

The toxic effect of oxidized-heme, also known as hemin, is implicated in developing adverse clinical outcome in various hematolytic diseases. To simulate and reconstruct the molecular events associated with hemin exposure on circulating monocytes, we employed a THP-1 cell line based in vitro model. Flow cytometry and Western blot analyses were subsequently applied. Hemin-treated THP-1 produced ROS in a dose-dependent manner which resulted in 10–30 % of cell death primarily through apoptosis. Surviving cells induced autophagy which too was ROS-dependent, as revealed by application of N-acetyl-L-cysteine. Hemin-mediated autophagy promoted differentiation of CD14+ THP-1 cells into CD11b+ macrophages. Application of 3-methyladenine, reinforced that differentiation of THP-1 was an autophagy-dependent process. It was revealed that despite a higher polarization towards M2-macrophage, synthesis of pro-inflammatory cytokines namely TNF-α, IL-1A, IL-2, IL-8 and IL-17A predominated. IL-6, a pleiotropic cytokine, was also elevated. It may thus be surmised that hemin-induced pro-inflammatory response in THP-1 is downstream to ROS-dependent autophagy and monocyte differentiation. This finding is translationally meaningful as hemin is already approved by FDA for amelioration of acute porphyria and is actively considered as a therapeutic agent for other diseases. This study underscores the need of further research untangling the reciprocal regulation of inflammatory signaling and autophagy under oxidative stress.

Epidemiological and Prognostic Importance of New-Onset Cancer as a Net Adverse Clinical Outcome after ST-Elevation Myocardial Infarction.

The study assessed the epidemiological frequency and prognostic impact of new-onset cancer as an additional net adverse clinical outcome in patients after ST-elevation myocardial infarction (STEMI), considering its potential clinical significance alongside classical endpoints. This study was designed as a single-center observational study, including 1285 consecutive patients who were diagnosed as STEMI patients as the subject, and the frequency and prognosis of new-onset cancer after STEMI onset were assessed. The incidence of all-cause death, nonfatal myocardial infarction (MI), stroke, and bleeding were analyzed as classical endpoints. Throughout an average of a 1241.4 days observation period, cancers were observed in 7.0% of patients (n = 90), showing development at a constant rate throughout this period (incidence rate, 0.06/1000 person-years). The average duration from STEMI onset to cancer diagnosis was 1371.4 days. Death, MI, or stroke were observed in 21.3%, 4.0%, 6.5%, and 12.8%, giving incidence rates of 0.18, 0.03, 0.06, and 0.11/1000 person-years, respectively. Long-term mortality was higher in patients with newly diagnosed cancer than in patients without cancer (36.7% vs. 20.1%, p < 0.01). Cancer after STEMI should be considered as an additional major adverse clinical event because of its high incidence, constant development, and high mortality in comparison to classical endpoints.

The Role of Adrenomedullin as a Predictive Marker of the Risk of Death and Adverse Clinical Events: A Review of the Literature.

Adrenomedullin (ADM) is a vasodilatory peptide that plays a crucial role in maintaining cardiovascular health through its various biological functions. ADM was discovered in the acidic extract of human pheochromocytoma tissue and has been recognized for its significant effects on the vascular system. The main functions of ADM include vasodilation, controlling blood pressure and maintaining vascular integrity, although its role on cardiovascular health is broader. Research has shown that elevated levels of adrenomedullin have been observed in a large number of severe diseases, with high risk of death. In this work, we examined the role of ADM as a predictive molecule of the risk of mortality and adverse clinical outcome through a narrative review of the scientific literature. The results were divided based on the pathologies and anatomical districts examined. This review demonstrates how ADM shows, in many diseases and different systems, a close correlation with the risk of mortality. These results prove the value of ADM as a prognostic marker in various clinical contexts and diseases, with utility in the stratification of the risk of clinical worsening and/or death and in the evaluation of therapeutic efficacy. The results open new perspectives with respect to the concrete possibility that ADM enters clinical practice as an effective diagnostic and prognostic marker of death as well as a molecular target for therapies aimed at patient survival.

N-acetylgalactosaminyltransferase GALNT6 is a potential therapeutic target of clear cell renal cell carcinoma progression.

High expression of truncated O-glycans Tn antigen predicts adverse clinical outcome in patients with clear cell renal cell carcinoma (ccRCC). To understand the biosynthetic underpinnings of Tn antigen changes in ccRCC, we focused on N-acetylgalactosaminyltransferases (GALNTs, also known as GalNAcTs) known to be involved in Tn antigen synthesis. Data from GSE15641 profile and local cohort showed that GALNT6 was significantly upregulated in ccRCC tissues. The current study aimed to determine the role of GALNT6 in ccRCC, and whether GALNT6-mediated O-glycosylation aggravates malignant behaviors. Gain- and loss-of-function experiments showed that overexpression of GALNT6 accelerated ccRCC cell proliferation, migration, and invasion, as well as promoted ccRCC-derived xenograft tumor growth and lung metastasis. In line with this, silencing of GALNT6 yielded the opposite results. Mechanically, high expression of GALNT6 led to the accumulation of Tn antigen in ccRCC cells. By undertaking immunoprecipitation coupled with liquid chromatography/mass spectrometry, vicia villosa agglutinin blot, and site-directed mutagenesis assays, we found that O-glycosylation of prohibitin 2 (PHB2) at Ser161 was required for the GALNT6-induced ccRCC cell proliferation, migration, and invasion. Additionally, we identified lens epithelium-derived growth factor (LEDGF) as a key regulator of GALNT6 transcriptional induction in ccRCC growth and an upstream contributor to ccRCC aggressive behavior. Collectively, our findings indicate that GALNT6-mediated abnormal O-glycosylation promotes ccRCC progression, which provides a potential therapeutic target in ccRCC development.

Hallmarks of cancer in patients with heart failure: data from BIOSTAT-CHF

BackgroundWithin cardio-oncology, emerging epidemiologic studies have demonstrated a bi-directional relationship between heart failure (HF) and cancer. In the current study, we aimed to further explore this relationship and investigate the underlying pathophysiological pathways that connect these two disease entities.MethodsWe conducted a post-hoc analysis in which we identified 24 Gene Ontology (GO) processes associated with the hallmarks of cancer based on 92 biomarkers in 1960 patients with HF. We performed Spearman’s correlations and Cox-regression analyses to evaluate associations with HF biomarkers, severity and all-cause mortality.ResultsOut of a total of 24 GO processes, 9 biological processes were significantly associated with adverse clinical outcome. Positive regulation of mononuclear cell proliferation demonstrated the highest hazard for reaching the clinical endpoint, even after adjusting for confounders: all-cause mortality HR 2.00 (95% CI 1.17–3.42), p = 0.012. In contrast, negative regulation of apoptotic process was consistently associated with a lower hazard of reaching the clinical outcome, even after adjusting for confounders: all-cause mortality HR 0.74 (95% CI 0.59–0.95), p = 0.016. All processes significantly correlated with HF biomarkers, renal function and HF severity.ConclusionsIn patients with HF, GO processes associated with hallmarks of cancer are associated with HF biomarkers, severity and all-cause mortality.

Sarcopenia in cirrhosis of liver - comparison of different tools in diagnosis

BACKGROUND AND AIMS Sarcopenia in liver cirrhosis is a common condition associated with increased mortality and adverse clinical outcome. Early recognition and treatment is essential but challenging. Clinical detection of sarcopenia with various assessment tools gives indirect knowledge of muscle mass and strength. The aim of this study is to find the most easy and applicable assessment tool in daily clinical practice to diagnose sarcopenia. METHODS A retrospective observational study was conducted and data was taken from electronic medical records of patients admitted with cirrhosis and sarcopenia in department of gastroenterology of Tribhuvan university Teaching hospital. A total of 51 cirrhotic patients were included during one and half year study duration. Sarcopenia was assessed using assessment tool like hand grip strength, chair stand test, 400 metre walk test and CT measurement of either skeletal muscle area (SMA) or skeletal muscle index (SMI). RESULTS Among 51 patients assessed with performance based assessment tool to diagnose sarcopenia, taking CT as gold standard test, SARC-F score and chair stand test were found to have highest sensitivity and specificity of 93%, 87.5 % and 93%, 100% respectively. CONCLUSION Diagnosis of sarcopenia with simple clinic based assessment tool SARC-F score and chair stand test is very useful and comparable with more costly and resource-intensive CT scan.

Mid-term clinical outcomes of left bundle branch area pacing compared to accurate right ventricular septal pacing.

Although left bundle branch area pacing (LBBAP) reportedly results in fewer adverse outcomes after implantation than conventional stylet-guided right ventricular septal pacing (RVSP), previous studies have not compared LBBAP with accurate RVSP using a delivery catheter. The aim of this study was to compare clinical outcomes between LBBAP and accurate RVSP among patients with atrioventricular block (AVB). This single-center observational study enrolled 160 patients requiring RV pacing due to symptomatic AVB between September 2018 and December 2021. Primary composite outcomes included all-cause death, hospitalization due to heart failure (HF), and upgrading to biventricular pacing. Secondary composite outcomes included any procedural and postprocedural complications. Overall, 160 patients were analyzed (LBBAP, n = 81; RVSP, n = 79). No significant differences in baseline characteristics were observed between the two groups. The RV pacing burden at 1year after implantation was 90.8% ± 20.4% and 86.2% ± 22.6%, respectively (p = 0.21). During a mean follow-up of 840 ± 369days, the incidence of the primary outcome was significantly lower with LBBAP (4.9%) compared to RVSP (22.8%) (Log-rank p = 0.02). There was no significant difference in the incidence of the secondary outcome between the two groups (3.7% vs. 5.1%, p = 0.65). In the multivariate analysis, baseline QRS duration, RV pacing burden, and LBBAP were independently associated with the primary outcome (baseline QRS duration: hazard ratio [HR], 1.01; 95% confidence interval [CI], 1.00-1.02; p < 0.001; RV pacing burden: HR, 1.01; 95% CI, 1.00-1.02; p < 0.001; LBBAP: HR, 0.45; 95% CI, 0.31-0.64; p < 0.001). In patients requiring frequent RV pacing, LBBAP was associated with reduced adverse clinical outcome compared to accurate RVSP using a delivery catheter.

The predictive value of GLIM criteria on clinical outcomes and responses to nutritional support in patients with neurocritical illnesses

Neurocritically ill patients frequently exhibit coma, gastroparesis, and intense catabolism, leading to an increased risk of malnutrition. The Global Leadership Initiative on Malnutrition (GLIM) criteria for the diagnosis of malnutrition was created to achieve a consistent malnutrition diagnosis across diverse populations. This study aimed to validate the concurrent and predictive validity of GLIM criteria in patients with neurocritical illnesses. A total of 135 participants were followed from admission to the neurocritical unit (NCU) until discharge. Comparing GLIM criteria to the Subjective Global Assessment (SGA), sensitivity was 0.95 and specificity was 0.69. Predictive validity of GLIM criteria was assessed using a composite adverse clinical outcome, comprising mortality and various major complications. Adjusted hazard ratios for moderate and severe malnutrition were 2.86 (95% CI 1.45–5.67) and 3.88 (95% CI 1.51–9.94), respectively. Changes in indicators of nutritional status, including skeletal muscle mass and abdominal fat mass, within 7 days of admission were obtained for 61 participants to validate the predictive capability of the GLIM criteria for the patients’ response of standardized nutritional support. The GLIM criteria have a statistically significant predictive validity on changes in rectus femoris muscle thickness and midarm muscle circumference. In conclusion, the GLIM criteria demonstrate high sensitivity for diagnosing malnutrition in neurocritically ill patients and exhibit good predictive validity.

Predictors And Associated Outcomes Of Adherence To Treatment In Russian Patients Undergoing Corneal Transplantation

Corneal blindness affects approximately 8 million people worldwide. The effectiveness of keratoplasty depends on several factors, including surgical technique, clinical characteristics of the patients, and social factors such as their adherence to treatment. Objective — To analyze nonattendance of doctor’s appointments and associated clinical outcomes in Russian patients who underwent high-risk and low-risk penetrating keratoplasty (PKP). Material and Methods — We conducted a retrospective cohort study to analyze the pre- and postoperative records of patients who underwent PKP. The low-risk group included 28 people with keratoconus (their mean age was 33±3 years), while high-risk group included 54 people with corneal opacity of various etiologies (their mean age was 67±13 years). The study assessed adherence to treatment by examining attendance at postoperative physician visits. Successful corneal transplant engraftment was considered favorable outcome, whereas graft failure or opacification was considered adverse outcome. The duration of observation was 12 months. Results — Patients in the low-risk group were twice as likely to attend postoperative appointments compared with patients in the high-risk group (p=0.0001). Patients over 70 years of age showed lower adherence to treatment (p=0.016), while those with higher education had significantly improved appointment attendance (p=0.017). Moreover, poor adherence increased the odds of adverse PKP outcome at 12 months in high-risk patients (OR=4.31; p=0.045). Conclusion — Failure to attend postoperative appointments in the high-risk group was associated with older patient age and lower education level, and correlated with adverse clinical outcome in Russian patients.

High stress hyperglycemia ratio predicts adverse clinical outcome in patients with coronary three-vessel disease: a large-scale cohort study

BackgroundCoronary three-vessel disease (CTVD) accounts for one-third of the overall incidence of coronary artery disease, with heightened mortality rates compared to single-vessel lesions, including common trunk lesions. Dysregulated glucose metabolism exacerbates atherosclerosis and increases cardiovascular risk. The stress hyperglycemia ratio (SHR) is proposed as an indicator of glucose metabolism status but its association with cardiovascular outcomes in CTVD patients undergoing percutaneous coronary intervention (PCI) remains unclear.Methods10,532 CTVD patients undergoing PCI were consecutively enrolled. SHR was calculated using the formula: admission blood glucose (mmol/L)/[1.59×HbA1c (%)–2.59]. Patients were divided into two groups (SHR Low and SHR High) according to the optimal cutoff value of SHR. Multivariable Cox regression models were used to assess the relationship between SHR and long-term prognosis. The primary endpoint was cardiovascular (CV) events, composing of cardiac death and non-fatal myocardial infarction (MI).ResultsDuring the median follow-up time of 3 years, a total of 279 cases (2.6%) of CV events were recorded. Multivariable Cox analyses showed that high SHR was associated with a significantly higher risk of CV events [Hazard Ratio (HR) 1.99, 95% Confidence interval (CI) 1.58–2.52, P < 0.001). This association remained consistent in patients with (HR 1.50, 95% CI 1.08–2.10, P = 0.016) and without diabetes (HR 1.97, 95% CI 1.42–2.72, P < 0.001). Additionally, adding SHR to the base model of traditional risk factors led to a significant improvement in the C-index, net reclassification and integrated discrimination.ConclusionsSHR was a significant predictor for adverse CV outcomes in CTVD patients with or without diabetes, which suggested that it could aid in the risk stratification in this particular population regardless of glucose metabolism status.

Biological functions and therapeutic potential of SRY related high mobility group box 5 in human cancer.

Cancer is a heavy human burden worldwide, with high morbidity and mortality. Identification of novel cancer diagnostic and prognostic biomarkers is important for developing cancer treatment strategies and reducing mortality. Transcription factors, including SRY associated high mobility group box (SOX) proteins, are thought to be involved in the regulation of specific biological processes. There is growing evidence that SOX transcription factors play an important role in cancer progression, including tumorigenesis, changes in the tumor microenvironment, and metastasis. SOX5 is a member of SOX Group D of Sox family. SOX5 is expressed in various tissues of human body and participates in various physiological and pathological processes and various cellular processes. However, the abnormal expression of SOX5 is associated with cancer of various systems, and the abnormal expression of SOX5 acts as a tumor promoter to promote cancer cell viability, proliferation, invasion, migration and EMT through multiple mechanisms. In addition, the expression pattern of SOX5 is closely related to cancer type, stage and adverse clinical outcome. Therefore, SOX5 is considered as a potential biomarker for cancer diagnosis and prognosis. In this review, the expression of SOX5 in various human cancers, the mechanism of action and potential clinical significance of SOX5 in tumor, and the therapeutic significance of Sox5 targeting in cancer were reviewed. In order to provide a new theoretical basis for cancer clinical molecular diagnosis, molecular targeted therapy and scientific research.
