RESUMO
Background: Heart failure, a major public health concern, significantly contributes to hospital admissions. This study evaluates the impact of malnutrition on both patient and hospital outcomes in heart failure admissions, with a specific focus on variations in outcomes based on the severity of malnutrition. Methods: Utilizing the National Inpatient Sample (NIS) database, this retrospective cohort study included adult patients admitted with a principal diagnosis of heart failure. Malnutrition was identified using the well-validated ICD 10 codes. We compared outcomes between patients with and without malnutrition, focusing on mortality, length of stay (LOS), hospital charges, cardiac arrest, and cardiogenic shock. Results: Out of 1,110,085 heart failure patients, 36,522 (3.29%) were malnourished. Malnourished patients exhibited significantly higher adjusted in-hospital mortality rates (aOR 3.32; 95% CI 3.03-3.64), longer LOS (mean increase of 4.67 days; p < 0.001), and higher hospital charges (mean increase of USD 77,416.9; p < 0.01). Increased rates of cardiac arrest (aOR 2.39; 95% CI 1.99-2.86; p < 0.001) and cardiogenic shock (aOR 3.74; 95% CI 3.40-4.12; p < 0.001) were also noted in malnourished patients. Severely malnourished patients faced worse outcomes compared to those with mild to moderate malnutrition. Conclusions: Heart failure patients with malnutrition experience higher mortality rates, longer hospital stays, increased hospitalization charges, and greater complication rates, including cardiac arrest and cardiogenic shock, compared to non-malnourished patients. Outcomes deteriorate with the increasing severity of malnutrition. Timely and individualized nutritional interventions may significantly improve outcomes for heart failure admissions.
RESUMO
INTRODUCTION: Heart failure is a pressing public health concern, affecting millions in the United States and projected to rise significantly by 2030. Iron deficiency, prevalent in nearly half of ambulatory heart failure patients, contributes to anemia and diminishes patient outcomes. In this study, we aim to evaluate the impact of iron deficiency anemia on acute heart failure hospitalizations outcomes. METHODS: Utilizing the 2019 National Inpatient Sample (NIS) database, a retrospective observational study assessed 112,864 adult patients hospitalized with heart failure and 7,865 cases also had a concomitant diagnosis of iron deficiency anemia (IDA). RESULTS: Among 112,864 heart failure hospitalizations in 2019, approximately 7% had concomitant iron deficiency anemia (IDA). Heart failure patients with IDA exhibited distinct demographic characteristics, with females comprising 51.1% (p < 0.01) and higher rates of complicated hypertension (p < 0.01), complicated diabetes (p < 0.01), and peripheral vascular disease (p < 0.01). Adjusted mean LOS for patients with IDA was significantly longer at 1.31 days (95% CI 0.71-1.47; p < 0.01), persisting in both HFpEF and HFrEF subgroups. While total hospital charges were comparable in HFpEF, HFrEF patients with IDA incurred significantly higher charges ($13427.32, 95% CI: 1463.35-$25391.29, p = 0.03) than those without IDA. Complications such as atrial fibrillation and acute kidney injury were notably more prevalent in HFpEF and HFrEF patients with IDA. CONCLUSION: The study highlighted that iron deficiency in heart failure patients leads to extended hospital stays, increased costs, and heightened risks of specific complications, particularly in HFrEF. Our study emphasized the implications of IDA in patients with heart failure ranging from prolonged hospitalizations and increased costs. Addressing iron deficiency is crucial, given its substantial impact on heart failure hospitalizations and outcomes, emphasizing the need for proactive diagnosis and management.
RESUMO
Purpose: We conducted a comprehensive meta-analysis to compare the effects of balanced crystalloids (BC) and isotonic saline (IS) in pediatric sepsis. Methods: A systematic search was performed for studies comparing BC and IS in pediatric sepsis. Outcomes included mortality, acute kidney injury (AKI), need for renal replacement therapy (RRT), hospital length of stay (LOS), and pediatric intensive care unit (PICU) LOS. A random-effect models was used to calculated pooled odds ratios (OR) and mean differences (MD) with 95% confidence intervals (CIs). Results: The analysis included six studies with 8753 children. BC demonstrated significant reductions in overall mortality (OR 0.84, 95% CI 0.71 to 0.98, P = 0.03, I2 = 0%) and AKI (OR 0.74, 95% CI 0.57 to 0.96, P = 0.03, I2 = 37%) compared to IS. RRT need was similar between the BC and IS groups (OR 0.79, 95% CI 0.60 to 1.02, P = 0.07, I2 = 0%). Hospital and PICU LOS did not differ significantly. However, subgroup analysis of randomized controlled trials revealed significantly shorter hospital LOS in the BC group (mean difference -0.66 days, 95% CI -1.10 to -0.23, P = 0.003, I2 = 0%). Conclusion: Our meta-analysis demonstrates that using BC in pediatric sepsis is associated with reduced mortality, AKI, and hyperchloremia rates compared to IS, while maintaining similar hospital and PICU LOS. Large-scale randomized controlled trials are needed to validate these findings.
RESUMO
BACKGROUND: Vasovagal syncope (VVS) is a prevalent condition characterized by a sudden drop in blood pressure and heart rate, leading to a brief loss of consciousness and postural control. Recurrent episodes of VVS significantly impact the quality of life and are a common reason for emergency department visits. Non-pharmacological interventions, such as tilt training, physical counter pressure maneuvers, and yoga, have been proposed as potential treatments for VVS. However, their efficacy in preventing VVS remains uncertain. METHODS: A systematic review and meta-analysis were conducted following PRISMA guidelines. PubMed, Web of Science, and Embase were searched up to March 2023 for randomized controlled trials comparing non-pharmacological interventions with control in preventing VVS recurrence. The primary outcome was the recurrence rate of VVS episodes. RESULTS: A total of 1130 participants from 18 studies were included in the meta-analysis. The overall mean effect size for non-pharmacological interventions versus control was 0.245 (95 % CI: 0.128-0.471, p-value <0.001). Subgroup analysis showed that yoga had the largest effect size (odds ratio 0.068, 95 % CI: 0.018-0.250), while tilt training had the lowest effect size (odds ratio 0.402, 95 % CI: 0.171-0.946) compared to control. Physical counter pressure maneuvers demonstrated an odds ratio of 0.294 (95 % CI: 0.165-0.524) compared to control. CONCLUSION: Non-pharmacological interventions show promise in preventing recurrent VVS episodes. Yoga, physical counter pressure maneuvers, and tilt training can be considered as viable treatment options. Further research, including randomized studies comparing pharmacological and non-pharmacological approaches, is needed to evaluate the safety and efficacy of these interventions for VVS treatment.

Plasma exchange (PE) is a promising therapeutic option in patients with acute liver failure (ALF) and acute-on-chronic liver failure (ACLF). However, the impact of PE on patient survival in these syndromes is unclear. We aimed to systematically investigate the use of PE in patients with ALF and ACLF compared with standard medical therapy (SMT). We searched PubMed/Embase/Cochrane databases to include all studies comparing PE versus SMT for patients ≥ 18 years of age with ALF and ACLF. Pooled risk ratios (RR) with corresponding 95% CIs were calculated by the Mantel-Haenszel method within a random-effect model. The primary outcome was 30-day survival for ACLF and ALF. Secondary outcomes were overall and 90-day survival for ALF and ACLF, respectively. Five studies, including 343 ALF patients (n = 174 PE vs. n = 169 SMT), and 20 studies, including 5,705 ACLF patients (n = 2,856 PE vs. n = 2,849 SMT), were analyzed. Compared with SMT, PE was significantly associated with higher 30-day (RR 1.41, 95% CI 1.06-1.87, p = 0.02) and overall (RR 1.35, 95% CI 1.12-1.63, p = 0.002) survival in ALF patients. In ACLF, PE was also significantly associated with higher 30-day (RR 1.36, 95% CI 1.22-1.52, p < 0.001) and 90-day (RR 1.21, 95% CI 1.10-1.34, p < 0.001) survival. On subgroup analysis of randomized controlled trials, results remained unchanged in ALF, but no differences in survival were found between PE and SMT in ACLF. In conclusion, PE is associated with improved survival in ALF and could improve survival in ACLF. PE may be considered in managing ALF and ACLF patients who are not liver transplant (LT) candidates or as a bridge to LT in otherwise eligible patients. Further randomized controlled trials are needed to confirm the survival benefit of PE in ACLF.

Hypertrophic cardiomyopathy (HCM) is a complex cardiac disorder, often associated with adverse outcomes, including sudden cardiac death. Myocardial bridging (MB), where a coronary artery segment traverses intramurally within the myocardium, complicates coronary blood flow dynamics. This retrospective study investigates the relationship between MB and HCM and their impact on percutaneous coronary intervention (PCI) outcomes. Data from the 2019 National Inpatient Sample (NIS), representing 20% of U.S. hospitalizations, was utilized. Patients with both HCM and MB undergoing PCI were identified and analyzed. The study assessed inpatient outcomes, including mortality, length of stay, hospital cost, and post-PCI complications (atrial fibrillation, acute kidney injury, bleeding, coronary dissection). Patients with HCM and MB exhibited distinct demographics. The study did not find significant associations between HCM/MB and inpatient mortality, length of stay, or hospital cost. However, HCM patients had a higher incidence of atrial fibrillation and acute kidney injury post-PCI (aOR 2.33, 95% CI 1.46 to 3.71, p ≤ 0.001). MB was linked to increased occurrences of acute heart failure (aOR 0.62, 95% CI 0.42-0.92, pâ¯=â¯0.02) and post-PCI bleeding (aOR 4.88, 95% CI 1.17-20.2, pâ¯=â¯0.03). This nationwide study reveals unique demographic profiles for HCM and MB patients. Notably, HCM patients face higher risks of post-PCI complications, including atrial fibrillation and acute kidney injury. These findings provide fresh insights into the MB-HCM relationship and its implications for PCI outcomes. They emphasize the need for tailored interventions and improved patient management in cases involving both HCM and MB.

INTRODUCTION: The effectiveness of extracorporeal membrane oxygenation (ECMO) in treating COVID-19 patients has been variable. To gain a better insight, we examined the outcomes of ECMO in COVID-19 patients using data from the 2020 National Inpatient Sample database. METHODS: We analyzed data from adult hospital admissions where COVID-19 was the primary diagnosis. The primary outcome was all-cause inpatient mortality. Secondary outcomes were length of stay (LOS), cost, and discharge disposition. RESULTS: We identified 1,048,025 COVID-19 admissions, of which 98,528 were on mechanical ventilation (MV), and only 1.8% received ECMO. In-hospital mortality of mechanically ventilated patients who received ECMO was 49%, compared to 59% with no ECMO (p < 0.001). ECMO treatment was associated with a reduced risk of mortality (HR = 0.67, p < 0.0001, CI 0.57-0.79) even after adjustment for confounders and other comorbidities. Patients on ECMO had significantly extended hospital stays and were more likely to be discharged to an acute care facility. Younger and male patients were more likely to receive ECMO treatment. Females had a lower mortality risk, while race and obesity were not associated with an increased risk of death. CONCLUSION: ECMO treatment may offer survival benefits in severe COVID-19. Based on our findings, we suggest early ECMO treatment for patients with a high mortality risk.
RESUMO
BACKGROUND: Cardiovascular disease, particularly acute coronary syndromes (ACS), is the leading cause of death in the United States. Minor fluctuations in hospital admissions for different conditions, including ACS, can be seen throughout the year. This study focuses on the impact of admission month on outcomes of acute coronary syndromes during the first year of the COVID-19 pandemic. METHODS: This was a retrospective observational study of patients hospitalized with ACS from the National Inpatient Sample, during the years 2020 (n = 779,895) and 2019 (n = 935,975). We compared the monthly outcomes for every month to the outcomes for the month of January of that same year. The primary outcomes of interest were in-hospital mortality and time from admission to PCI. RESULTS: Inpatient mortality for patients admitted with STEMI was significantly higher for admissions in the months of April, October and December of 2020 than January of that same year. For patients admitted with NSTEMI or UA, inpatient mortality was higher for admissions in April and December 2020 when compared to admissions in January 2020. Inpatient mortality for patients with STEMI, NSTEMI and UA was not different based on admission month in the year 2019. CONCLUSION: The month of admission significantly affected outcomes for patients admitted with ACS during the COVID-19 pandemic, with higher inpatient mortality and longer time from admission to PCI for certain months in 2020. Further studies should investigate disparities in monthly ACS outcomes for the year 2021 and onward, now that COVID-19 infections have been steadily declining.
RESUMO
Diffuse alveolar hemorrhage (DAH) syndrome is characterized by bleeding into the alveolar spaces of the lungs and occurs when there is an injury to the alveolar microcirculation that leads to hemorrhage from the alveolar capillaries. We report a case of an 82-year-old woman who presented with acute respiratory distress. The patient had a history of rheumatoid arthritis (RA) and was on amiodarone for atrial fibrillation therapy. Initial diagnostic workup, including bronchoscopy and imaging studies, revealed diffuse opacities and the bronchoalveolar lavage fluid consistent with DAH. The patient required aggressive management with supportive care and corticosteroids. Laboratory work showed a synergistic effect between amiodarone and RA in inducing DAH. This makes the report unique as no reports in the literature described a synergic effect of amiodarone and RA in inducing DAH. The primary objective of this report is to guide physicians and remind them to keep DAH at the top of their differential diagnosis in the setting of an RA patient taking amiodarone.

The influence of body mass index (BMI) on Transcatheter Aortic Valve Replacement (TAVR) outcomes has been the focus of several previous studies. In this study, we examined the relationship between BMI and various clinical outcomes following TAVR procedures. A comprehensive analysis was conducted using a large cohort of patients who underwent TAVR. In this study, we identified patients who underwent Transcatheter aortic valve replacement (TAVR) in the year 2020. Procedure Classification System (ICD-10-PCS) codes were used to identify TAVR cases. The weighted final study sample included 77319 TAVR hospitalizations. Patients were categorized into 5 groups based on their Body Mass Index (BMI. Our findings revealed that there was no significant difference in in-hospital mortality among different BMI groups when compared to patients with a normal BMI (20 to 24.9). patients with a BMI of 25 or higher demonstrated a statistically significant shorter duration of hospitalization compared to those with a normal BMI. patients with a BMI ranging between 30 and 39.9 exhibited decreased hospitalization costs when compared to patients with a normal BMI. Moreover, our study revealed a decrease in atrial fibrillation, acute heart failure and acute kidney injury complications following TAVR in patients with above-normal BMI. Despite similar in-hospital mortality across BMI groups, having a BMI of 25 or greater is associated with improved immediate outcomes following TAVR. These benefits in overweight and obese patients are consistent with findings described in recent literature. Further studies are warranted to explore the underlying mechanisms and potential implications of these associations, as well as to optimize patient selection and management strategies for TAVR procedures.

BACKGROUND: The incidence and prevalence of heart failure (HF) in the United States has steadily increased in the past few decades. Similarly, the United States has experienced an increase in HF-related hospitalizations which has added to the burden of a resource-stretched healthcare system. With the emergence of the coronavirus disease 2019 (COVID-19) pandemic in 2020, hospitalizations due to the COVID-19 infection sky-rocketed further exacerbating the burden on both patient health and the healthcare system. The focus of this study is to examine how a secondary COVID-19 diagnosis affects the outcome of HF patients, and how a pre-existing diagnosis of heart failure impacts the outcomes of patients hospitalized with COVID-19 infection. METHODS: This was a retrospective observational study of adult patients hospitalized with heart failure and COVID-19 infection in the United States in the years 2019 and 2020. Analysis was conducted using the National Inpatient Sample (NIS) database of the Healthcare Utilization Project (HCUP). The total number of patients included in this study from the NIS database 2020 was 94,745. Of those, 93,798 had heart failure without a secondary diagnosis of COVID-19; 947 had heart failure along with a secondary diagnosis of COVID-19. The primary outcome of our study was in-hospital mortality, length of stay, total hospital charges and time from admission to right heart catheterization, which were compared between the two cohorts. Results: Our main study findings are that mortality in HF patients with secondary diagnosis of COVID-19 infection was not statistically different compared to those who were without a secondary diagnosis of COVID-19. Our study findings also showed that length of stay (LOS) and hospital costs in HF patients who had a secondary diagnosis of COVID-19 were not statistically different compared to those who did not have the secondary diagnosis. Time from admission to right heart catheterization (RHC) in HF patients who had a secondary diagnosis of COVID-19 was shorter in heart failure with reduced ejection fraction (HFrEF) but not in heart failure preserved ejection fraction (HFpEF) compared to those without secondary diagnoses of COVID-19. Finally, when evaluating hospital outcomes for patients admitted with COVID-19 infection, we found that inpatient mortality increased significantly when they had a pre-existing diagnosis of heart failure. CONCLUSION: The COVID-19 pandemic significantly impacted hospitalization outcomes for patients admitted with heart failure. The time from admission to right heart catheterization was significantly shorter in patients admitted with heart failure reduced ejection fraction who also had a secondary diagnosis of COVID-19 infection. When evaluating hospital outcomes for patients admitted with COVID-19 infection, we found that inpatient mortality increased significantly when they had a pre-existing diagnosis of heart failure. Length of hospital stay and hospital charges also were higher for patients with COVID-19 infection who had pre-existing heart failure. Further studies should focus not just on how medical comorbidities like COVID-19 infection, affect outcomes of heart failure but also on how overall strains on the healthcare system, such as pandemics, may affect the management of conditions such as heart failure.
RESUMO
SARS-CoV-2 vaccinations were found to be highly effective in phase 3 clinical trials. However, these trials have not reported data regarding the subgroup of liver disease or excluded patients with liver disease. The effectiveness of COVID-19 vaccines among liver cirrhosis (LC) patients is unclear. We conducted this meta-analysis to assess the effectiveness of SARS-CoV-2 vaccination in LC patients. A comprehensive literature search was conducted to include all the relevant studies that compared the outcomes of LC patients who received SARS-CoV-2 vaccines vs. unvaccinated patients. Pooled risk ratios (RRs) with 95% confidence intervals (CIs) were calculated by the Mantel-Haenszel method within a random-effect model. Four studies with 51,834 LC patients (20,689 patients received at least one dose vs 31,145 were unvaccinated) were included. COVID-19-related complications, including hospitalization (RR 0.73, 95% CI 0.59-0.91, P = 0.004), mortality (RR 0.29, 95% CI 0.16-0.55, P = 0.0001), and need for invasive mechanical ventilation (RR 0.29, 95% CI 0.11-0.77, P = 0.01), were significantly lower in the vaccinated group compared to the unvaccinated group. SARS-CoV-2 vaccination in LC patients reduced COVID-19-related mortality, intubation, and hospitalization. SARS-CoV-2 vaccination is highly effective in LC. Further prospective studies, preferably randomized controlled trials, are necessary to validate our findings and determine which vaccine is superior in patients with LC.
RESUMO
BACKGROUND: Coronavirus disease 2019 (COVID-19) caused significant morbidity and mortality worldwide. There is limited information describing the hospital outcomes of COVID-19 patients in regard to specific body mass index (BMI) categories. METHODS: We utilized the Healthcare Cost and Utilization Project Nationwide Inpatient Sample (NIS) 2020 database to collect information on patients hospitalized for COVID-19 in the United States. Using the International Classification of Diseases, 10th revision, Clinical Modification (ICD-10-CM) coding system, adult patients (≥18 years of age) with a primary hospitalization for COVID-19 were identified. Adjusted analyses were performed to assess for mortality, morbidity, and resource utilization, and compare the outcomes among patients categorized according to BMI. RESULTS: A total of 305,284 patients were included in this study. Of them, 248,490 had underlying obesity, defined as BMI ≥ 30. The oldest patients were observed to have BMI < 19, while youngest patients were in the BMI > 50 category. BMI < 19 category had the highest crude in-hospital mortality rate. However, after adjusted regression, patients with BMI > 50 (adjusted odds ratio (aOR) 1.63, 95% CI 1.48-1.79, p-value < 0.001) had the highest increased odds, at 63%, of in-hospital mortality compared to all other patients in the study. Patients with BMI > 50 also had the highest increased odds of needing invasive mechanical ventilation (IMV) and mortality associated with IMV compared to all other patient, by 37% and 61%, respectively. Obese patients were noted to have shorter average hospital length of stay (LOS), by 1.07 days, compared to non-obese patients, but there was no significant difference in average hospitalization charges. CONCLUSION: Among obese patients primarily hospitalized with COVID-19, those with BMI ≥ 40 had significantly increased rates of all-cause in-hospital mortality, need for IMV, mortality associated with IMV, and septic shock. Overall, obese patients had shorter average hospital LOS, however, did not have significantly higher hospitalization charges.
