This study compares outcomes of patients admitted for atrial fibrillation (AF) with and without coexisting systemic lupus erythematosus (SLE). The primary outcome was inpatient mortality. Hospital length of stay (LOS), total hospital charges, odds of undergoing ablation, pharmacologic cardioversion and electrical cardioversion were secondary outcomes of interest. Data were abstracted from the National Inpatient Sample (NIS) 2016 and 2017 database. The NIS was searched for adult hospitalizations with AF as principal diagnosis with and without SLE as secondary diagnosis using International Classification of Diseases, Tenth Revision, Clinical Modification codes. Multivariate logistic and linear regression analysis was used accordingly to adjust for confounders. There were over 71 million discharges included in the combined 2016 and 2017 NIS database. 821,630 hospitalizations were for adult patients, who had a principal diagnosis of AF, out of which, 2645 (0.3%) had SLE as secondary diagnosis. Hospitalizations for AF with SLE had similar inpatient mortality (1.5% vs 0.91%, adjusted OR (AOR): 1.0, 95% CI 0.47 to 2.14, p=0.991), LOS (4.2 vs 3.4 days, p=0.525), total hospital charges ($51,351 vs $39,121, p=0.056), odds of undergoing pharmacologic cardioversion (0.38% vs 0.38%, AOR: 0.90, 95% CI 0.22 to 3.69, p=0.880) and electrical cardioversion (12.9% vs 17.5%, AOR 0.87, 95% CI 0.66 to 1.15, p=0.324) compared with those without SLE. However, SLE group had increased odds of undergoing ablation (6.8% vs 4.2%, AOR: 1.9, 95% CI 1.3 to 2.7, p

Background The Measurement Tool to Assess systematic Reviews (AMSTAR) 2 is a critical appraisal tool for systematic reviews (SRs) and meta-analyses (MAs) of interventions. We aimed to perform the first AMSTAR 2-based quality assessment of heart failure-related studies. Methods Eleven high-impact journals were searched from 2009 to 2019. The included studies were assessed on the basis of 16 domains. Seven domains were deemed critical for high-quality studies. On the basis of the performance in these 16 domains with different weights, overall ratings were generated, and the quality was determined to be “high,” “moderate,” “low,” or “critically low.” Results Eighty-one heart failure-related SRs with MAs were included. Overall, 79 studies were of “critically low quality” and two were of “low quality.” These findings were attributed to insufficiency in the following critical domains: a priori protocols (compliance rate, 5%), complete list of exclusions with justification (5%), risk of bias assessment (69%), meta-analysis methodology (78%), and investigation of publication bias (60%). Conclusions The low ratings for these potential high-quality heart failure-related SRs and MAs challenge the discrimination capacity of AMSTAR 2. In addition to identifying certain areas of insufficiency, these findings indicate the need to justify or modify AMSTAR 2’s rating rules.

Background Heart failure (HF) constitutes a huge public health burden today with acute respiratory infections being among the main precipitating causes for hospitalization. On the other hand, HF is a known risk factor for pneumonia which is the most common cause of adult hospital admissions in the United States. Objective To examine the effect of HF on the in-hospital outcomes of pneumonia Methods The National Inpatient Sample (NIS) database, 2016–2018, was queried for inpatient principal diagnosis of all-cause pneumonia, and the study group was stratified into those with and without HF as a secondary diagnosis, using International Classification of Diseases-10 (ICD-10) codes. Multivariate logistic and linear regression analyses were used to adjust for confounding. Stata 16 software was used for data analysis. Results 1,929,598 adults were hospitalized with the primary diagnosis of pneumonia, of which 499,740 (25.9%) had HF. The incidence of mortality was 4.2% (n=20,785) in those with HF compared to 2.0% (n=28,365) in those without HF. The adjusted odds ratio (aOR) of inpatient mortality for pneumonia patients with HF compared to those without HF was 1.35 (95% CI, 1.29–1.42; p Conclusion In patients hospitalized for pneumonia, HF is associated with increased odds of inpatient mortality and longer LOS. Complications such as arrhythmias, acute hypoxic respiratory failure, acute kidney injury, septic shock, cardiogenic shock and cardiac arrest occur more frequently in pneumonia patients with HF.

Cardiovascular effects of hypothyroidism include bradycardia, diastolic hypertension, atrial fibrillation, prolonged QT interval leading to torsades de pointes, varying degrees of AV block, accelerated coronary artery disease, and pericardial effusion. Cardiac tamponade is rare in patients with hypothyroidism because of pericardial distensibility and slow accumulation of fluid. The amount and rate of accumulation of pericardial effusion are related to the severity of hypothyroidism. Though rare, significant pericardial effusion can be a manifestation of subclinical hypothyroidism.

The preoperative differentiation of left ventricular aneurysm from pseudoaneurysm is a diagnostic challenge. This distinction is critical as the timing of surgical correction varies; elective for true aneurysm versus urgent for pseudoaneurysm. Our aim is to present a case report demonstrating these difficulties and to review imaging characteristics and the approach to distinguish the two entities.

The prognostic implications of ST-segment and T-wave (ST/T) abnormalities in patients undergoing stress SPECT-myocardial perfusion imaging (MPI) are not well defined. This was a single-center, retrospective cohort study of consecutive patients who underwent regadenoson stress SPECT-MPI. Patients with baseline electrocardiogram (ECG) abnormalities that impede ST/T analysis or those with known coronary artery disease were excluded. Patients were categorized as having primary ST abnormalities, secondary ST/T abnormalities due to ventricular hypertrophy or right bundle branch block, T-wave abnormalities, or normal ECG. The primary outcome was major adverse cardiovascular events (MACE) defined as the composite of cardiac death or myocardial infarction. Among 6,059 subjects, 1912 (32%) had baseline ST/T abnormalities. During a mean follow-up of 2.3 ± 1.9 years, the incidence of MACE was significantly higher among patients with secondary ST/T abnormalities compared to those with normal ECG (HR 2.05; 95% confidence interval [CI], 1.04-4.05; P = 0.039). No significant difference in MACE was observed among patients with primary ST abnormalities (HR 1.64; CI 0.87-3.06; P = 0.124) or T-wave abnormalities (HR 1.15; CI 0.62-2.16; P = 0.658) compared with patients who had normal ECG. Among patients with secondary ST/T changes, abnormal MPI was not associated with a significant increase in MACE rates compared to normal MPI (HR 1.18; CI 0.31-4.58; P = 0.808). However, abnormal MPI was associated with higher MACE rates among patients with primary ST abnormalities (HR 4.50; CI 1.44-14.10; P = 0.005) and T-wave abnormalities (HR 3.74; CI 1.20-11.68; P = 0.015). Similarly, myocardial ischemia on regadenoson stress SPECT-MPI was not associated with a significant increase in MACE rates in patients with secondary ST/T abnormalities (HR 1.45; CI 0.38-5.61; P = 0.588), while it was associated with a higher incidence of MACE in patients with primary ST abnormalities (HR 3.012; CI 0.95-9.53; P = 0.049) and T-wave abnormalities (HR 5.06; CI 1.60-15.96; P = 0.002). While patients with secondary ST/T abnormalities had significantly higher MACE risk, abnormal MPI or presence of myocardial ischemia on regadenoson SPECT-MPI in this group does not add prognostic information. Patients with primary ST abnormalities and T-wave abnormalities do not seem to have a significantly higher MACE risk compared to those with normal ECG; however, abnormal MPI or presence of myocardial ischemia, in these groups, correlates with higher MACE rates.

Systemic lupus erythematosus (SLE) is a chronic autoimmune disease with varied natural history and multisystemic involvement. The pathogenesis is multifactorial and complex precipitating the formation of autoantibodies. One of the main factors in SLE is the interaction between environmental triggers and genetic factors. Genome-wide association study technology has led to the identification of more than 80 loci which produce key proteins that lead to small pathophysiological changes and are associated with SLE. There has been an improvement in the management of the disease with newly standardized scores that have been validated in assessing disease activity and quality of life, and have helped in clinical care as well as research. The last five decades have seen a marked improvement in the prognosis of SLE, thanks to better general care and the development of newer immunosuppressive drugs, more specifically biological agents.

BackgroundIncreasing utilisation of hospice services has been a major focus in oncology, while only recently have cardiologists realised the similar needs of dying patients with heart failure (HF). We examined recent trends in locations of deaths in these two patient populations to gain further insight.MethodsComplete population-level data were obtained from the Mortality Multiple Cause-of-Death Public Use Record from the National Center for Health Statistics database, from 2013 to 2017. Location of death was categorised as hospital, home, hospice facility or nursing facility. Demographic characteristics evaluated by place of death included age, sex, race, ethnicity, marital status and education, and a multivariable logistic regression analysis was performed to analyse possible associations.ResultsAmong 2 780 715 deaths from cancer, 27% occurred in-hospital and 14% in nursing facilities; while among 335 350 HF deaths, 27% occurred in-hospital and 30% in nursing facilities. Deaths occurred at hospice facilities in 14% of patients with cancer, compared with just 8.7% in HF (p=0.001). For both patients with HF and cancer, the proportion of at-home and in-hospice deaths increased significantly over time, with majority of deaths occurring at home. In both cancer and HF, patients of non-Hispanic ethnicity (cancer: OR 1.29, (1.27 to 1.31), HF: OR 1.14, (1.07 to 1.22)) and those with some college education (cancer: OR 1.10, (1.09 to 1.11); HF: OR 1.06, (1.04 to 1.09)) were significantly more likely to die in hospice.ConclusionDeaths in hospital or nursing facilities still account for nearly half of cancer or HF deaths. Although positive trends were seen with utilisation of hospice facilities in both groups, usage remains low and much remains to be achieved in both patient populations.

A majority of the elderly suffer from chronic pain that significantly alters their daily activities and imposes an enormous burden on health care. Multiple comorbidities and the risk of polypharmacy in the elderly make it a challenge to determine the appropriate drug, dosage, and maintenance of therapy. Opioids are the most commonly used agents for this purpose in the elderly. The aim of this article is to discuss both the current well-established therapies used for managing chronic pain in the elderly and also the emerging newer therapies.

Retinal edema (RE) is commonest macular syndrome which is caused by formation of cyst segments within intraretinal pathology. RE can cause severe visual impairments or even blindness. Optical coherence tomography (OCT) imaging is the recently introduced eye testing technique that can detect early syndromes of retinal pathology. Many researchers have worked on the automated diagnosis of retinal pathology from fundus images. However, it is very difficult to detect early RE from fundus images and here we propose a discriminant analysis (DA) classifier based fully automated algorithm for the classification of RE using OCT images. We studied 75 OCT scans of 62 patients in which 14 persons had RE and 48 patients were healthy. Our proposed system achieved 100% accuracy for classification of RE patients and 91.86% for healthy subjects.
