Abstract Background Hypertrophic cardiomyopathy (HCM) is a heritable cardiac disorder characterized by increased left ventricular (LV) wall thickness, often leading to heart failure (HF). The role of cardiovascular magnetic resonance (CMR) imaging in predicting new onset of HF symptoms in patients with HCM remains unknown. This study aimed to identify CMR predictors of new-onset HF symptoms in individuals with HCM. Methods This study was a single-centre retrospective cohort study of HCM patients treated at a tertiary referral centre in the USA who underwent CMR examination between 1998 and 2018, had no HF symptoms at baseline CMR, and at least 1 year of follow-up. Clinical data were collected by review of electronic medical records, and CMR images were analyzed by a blinded expert cardiac radiologis. The primary outcome was new onset of HF symptoms, defined as New York Heart Association (NYHA) class ≥ II at follow-up. Kaplan–Meier analyses and Cox proportional hazard analyses were performed. Results Of 1462 patients diagnosed with HCM who had at least 1 CMR, 276 HCM patients without HF symptoms (average age 52.7 years, 33.3% female),median maximum left ventricular (LV) wall thickness was 19 mm ([IQR] 17–22) with a and median LV ejection fraction of 71% (IQR 66–77). Late gadolinium enhancement was detected in 56.2%) patients (60.7% had mild; 30.7% moderate; 8.6% severe). During a median follow-up period of 6.3 years, 93 patients developed HF symptoms (NYHA class II in 56 (60.2%); class III in 31 (33.3%); and class IV in 6 (6.5%). Multivariable analysis adjusted for age showed that LA enlargement (HR 1.626; 95% CI 1.01–2.62; P = .045) and LV mass index (HR 1.014; 95% CI 1.007–1.022; P≤ .001) and sex (HR 1.7; 95% CI 1.074–2.691; P = .023) were independent predictors of new onset of HF symptoms in patients with HCM. Conclusions Nearly half of the patients with HCM developed HF symptoms within 6.3 years. Left atrial enlargement, LV mass index, and sex were independent predictors of new onset of HF symptoms in HCM patients. These findings emphasize the value of CMR in HF risk stratification.
Emotional and psychosocial function after dorsal column spinal cord stimulator implantation: a systematic review and meta-analysis
Background The efficacy of spinal cord stimulation (SCS) in chronic pain studies is traditionally assessed by pain scores, which do not reflect the multidimensional nature of pain perception. Despite the evidence of SCS’s influence on emotional functioning comprehensive assessments of its effect remain lacking. Objective To assess changes in emotional and psychosocial functioning in patients who underwent SCS implantation for chronic pain. Evidence review Ovid MEDLINE, EMBASE, PsychINFO, Cochrane CENTRAL and Scopus databases were searched for original peer-reviewed publications reporting emotional functioning after SCS. The primary outcomes were a pooled mean difference (MD) in anxiety, depression, global functioning, mental well-being and pain catastrophizing at 12 months. The Grading of Recommendation, Assessment, Development, and Evaluation (GRADE) was used to determine the quality of evidence. Findings Thirty-two studies were included in the primary analysis. Statistically significant improvements were observed in anxiety (MD −2.16; 95% CI −2.84 to −1.49; p<0.001), depression (MD −4.66; 95% CI −6.26 to −3.06; p<0.001), global functioning (MD 20.30; 95% CI 14.69 to 25.90; p<0.001), mental well-being (MD 4.95; 95% CI 3.60 to 6.31; p<0.001), and pain catastrophizing (MD −12.09; 95% CI −14.94 to −9.23; p<0.001). Subgroup analyses revealed differences in Global Assessment of Functioning and mental well-being based on study design and in depression based on waveform paradigm. Conclusion The results highlight the statistically and clinically significant improvements in emotional and psychosocial outcomes in patients with chronic pain undergoing SCS therapy. However, these results need to be interpreted with caution due to the very low certainty of evidence per the GRADE criteria. PROSPERO registration CRD42023446326.
Measuring the concordance between endoscopic and histologic inflammation and its effect on IBD-associated dysplasia
Abstract Background and study aims Chronically inflamed colonic mucosa is primed to develop dysplasia identified at surveillance colonoscopy by targeted or random biopsies. We aimed to explore the effect of mucosal inflammation on detection of visible and “invisible” dysplasia and the concordance between the degree of endoscopic and histologic inflammation. Patients and methods This was a 6-year cross-sectional analysis of endoscopic and histologic data from IBD. A multinomial model was created to estimate the odds for a specific lesion type as well as the odds of random dysplasia relative to the degree of inflammation. Kappa statistics were used to measure concordance between endoscopic and histologic inflammation. Results A total of 3437 IBD surveillance colonoscopies between 2016–2021 were reviewed with 970 procedures from 721 patients containing 1603 visible lesions. Kappa agreement between histologic and endoscopic degree of inflammation was low at 0.4. There was a positive association between increased endoscopic inflammation and presence of tubulovillous adenomas (TVAs) (odds ratio [OR] 2.18; 95% confidence interval [CI] 1.03–4.62; P=0.04). Among cases with visible lesions, the yield of concomitant random dysplasia was 2.7% and 1.9% for random indefinite dysplasia. The odds of random dysplasia significantly increased as the degree of endoscopic and histologic inflammation increased (OR 2.18, 95%CI 1.46–3.26; P<0.001 and OR 2.75; 95%CI 1.65–4.57, P<0.001, respectively. The odds of indefinite random dysplasia also significantly increased as endoscopic and histologic inflammation increased (OR 2.90; 95%CI 1.85, 4.55, P<0.001 and OR 1.98; 95%CI 1.08, 3.62, P<0.035, respectively. Conclusions Endoscopic and histologic inflammation are associated with higher odds of finding TVAs and random low-grade, high-grade, and indefinite dysplasia. Concordance between histologic and endoscopic inflammation severity is low.
Mapping of Neuro-Cardiac Electrophysiology: Interlinking Epilepsy and Arrhythmia
The interplay between neurology and cardiology has gained significant attention in recent years, particularly regarding the shared pathophysiological mechanisms and clinical comorbidities observed in epilepsy and arrhythmias. Neuro-cardiac electrophysiology mapping involves the comprehensive assessment of both neural and cardiac electrical activity, aiming to unravel the intricate connections and potential cross-talk between the brain and the heart. The emergence of artificial intelligence (AI) has revolutionized the field by enabling the analysis of large-scale data sets, complex signal processing, and predictive modeling. AI algorithms have been applied to neuroimaging, electroencephalography (EEG), electrocardiography (ECG), and other diagnostic modalities to identify subtle patterns, classify disease subtypes, predict outcomes, and guide personalized treatment strategies. In this review, we highlight the potential clinical implications of neuro-cardiac mapping and AI in the management of epilepsy and arrhythmias. We address the challenges and limitations associated with these approaches, including data quality, interpretability, and ethical considerations. Further research and collaboration between neurologists, cardiologists, and AI experts are needed to fully unlock the potential of this interdisciplinary field.
Role of ketogenic diet in the management of cancer: A systematic review.
e24042 Background: Cancer is 2nd leading cause of death (1 in every 5) in the United States followed by heart disease. Use of ketogenic diet (KD)- high-fat & low-carbohydrate diet, allows fatty acids to become the obligatory source of cellular energy which can help in decreasing the tumor cell growth. Aim of this study was to evaluate role of KD in different types of cancer. Methods: We performed a systematic review using PRISMA protocol to identify articles describing the role of the ketogenic diet in cancer patients in PubMed. Keywords like cancer, neoplasm, tumor, KD, and intermittent fasting (IF) were used & filters like full text, English, human, observational studies, & clinical trials (CTs) were applied between 2018-2022. Results: Of the 362 studies after using filters only 22 studies were CTs. Of these 22, 12 studies were excluded & 10 studies were included in this study. [Table 1] We found CTs describing role of KD, IF or standard diet (SD) in brain cancer, non-metastasized rectal cancer, high-grade glioma, head and neck squamous cell carcinoma, locally advanced and metastatic breast cancer, ovarian and endometrial cancer. KD was describes as an accompanying measure for patients undergoing standard-of-care therapy that helps to improve the quality of life, survival & acceptable safety and tolerability. KD may augment the antitumor effects of classic chemotherapy and radiotherapy. Conclusions: Role of KD is described in depth, but majority RCT results were heterogeneous in nature to provide quantitative measures of survival timeline, outcomes, & recovery. Thus, more human prospective studies are warranted to evaluate the therapeutic effectiveness & safety of KD.[Table: see text]
A perilous and complicated situation in hospitals: Vitamin D deficiency in multiple myeloma patients—A nationwide cross-sectional study.
e20010 Background: For the year 2019, the United States age-adjusted rate of new Multiple Myeloma (MM) cases was 6.8 per 100,000 people and the age-adjusted death rate was 3 per 100,000 people. Vitamin D Deficiency (VDD) and associated complications are very common in MM patients. Aim of our study was to evaluate the prevalence and risk of VDD in patients with MM and VDD associated disability and mortality in the VDD patients. Methods: We performed a cross-sectional retrospective analysis of Nationwide Inpatient Sample data 2016-2018. Adults hospitalizations with MM were identified using ICD 10 code. Hospitalized patients were grouped into patients with VDD and without VDD. We ran chi square, unpaired-t test and mixed-effect survey logistic regression analysis to find out odds ratio and 95%CI showing outcomes of VDD in MM patients. Results: We found 330,175 hospitalizations with MM. Of these 11,480 were noted to be patients with VDD with higher prevalence (0.64% vs 0.37%) of and strong association (aOR:1.41, 95%CI:1.35-1.47) with MM in comparison without MM. Amongst MM, females [1.50, 1.49-1.51], black race [1.23, 1.22-1.24], urban teaching hospitals [1.22, 1.22-1.23], and hospitals in mid-west region [1.30, 1.29- 1.32] had higher prevalence odds of VDD compared with males, white race population, rural hospitals and hospitals in northeast region. (p<0.0001) Patients with VDD had higher prevalence and strong association with higher morbidity [5.1% vs 3.9%, 1.24,1.14-1.36; c-value=0.67], severe/extreme disability [77.2% vs 73.3%, 1.26, 1.20-1.33; c-value=0.73], and discharge to locations other than home [51.15% vs 45.69%, 1.29, 1.23-1.34; c-value=0.69] in comparison without VDD. (p<0.0001) [Table]. Conclusions: Significant poor outcomes warrant early identification of VDD and role of same hospitalization vitamin D replacement amongst MM patients with higher risk.
