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.

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. [ABSTRACT FROM AUTHOR]

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. [ABSTRACT FROM AUTHOR]

Simple Summary: Patients with cancer are considered a vulnerable population and might have an increased risk for severe outcomes of coronavirus disease 2019 (COVID-19). We used the Healthcare Cost and Utilization Project Nationwide Inpatient Sample (NIS) 2020 database, the largest inpatient database in the United States, to assess COVID-19 outcomes in cancer patients. We have demonstrated that cancer patients hospitalized for COVID-19 have increased odds of all-cause in-hospital mortality and acute respiratory failure compared with non-cancer patients. Lung cancer patients have been demonstrated to have the worst mortality outcome. Background: Coronavirus disease 2019 (COVID-19) caused significant mortality and mortality worldwide. There is limited information describing the outcomes of COVID-19 in cancer patients. Methods: We utilized the Healthcare Cost and Utilization Project Nationwide Inpatient Sample (NIS) 2020 database to collect information on cancer 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 (≥18 years) patients with COVID-19 were identified. Adjusted analyses were performed to assess for mortality, morbidity, and resource utilization among cancer patients. Results: A total of 1,050,045 patients were included. Of them, 27,760 had underlying cancer. Cancer patients were older and had more comorbidities. The all-cause in-hospital mortality rate in cancer patients was 17.58% vs. 11% in non-cancer. After adjusted logistic regression, cancer patients had a 21% increase in the odds of all-cause in-hospital mortality compared with those without cancer (adjusted odds ratio (aOR) 1.21, 95%CI 1.12–1.31, p-value < 0.001). Additionally, an increased odds in acute respiratory failure rate was found (aOR 1.14, 95%CI 1.06–1.22, p-value < 0.001). However, no significant differences were found in the odds of septic shock, acute respiratory distress syndrome, and mechanical ventilation between the two groups. Additionally, no significant differences in the mean length of hospital stay and the total hospitalization charges between cancer and non-cancer patients. Conclusion: Cancer patients hospitalized for COVID-19 had increased odds of all-cause in hospital mortality and acute respiratory failure compared with non-cancer patients. [ABSTRACT FROM AUTHOR]

Introduction: Inhaled pulmonary vasodilators (IPVD) have been previously studied in patients with non-coronavirus disease-19 (COVID-19) related acute respiratory distress syndrome (ARDS). The use of IPVD has been shown to improve the partial pressure of oxygen in arterial blood (PaO2), reduce fraction of inspired oxygen (FiO2) requirements, and ultimately increase PaO2/ FiO2 (P/F) ratios in ARDS patients. However, the role of IPVD in COVID-19 ARDS is still unclear. Therefore, we performed this meta-analysis to evaluate the role of IPVD in COVID-19 patients. Methods: Comprehensive literature search of PubMed, Embase, Web of Science and Cochrane Library databases from inception through April 22, 2022 was performed for all published studies that utilized IPVD in COVID-19 ARDS patients. The single arm studies and case series were combined for a 1-arm metaanalysis, and the 2-arm studies were combined for a 2-arm meta-analysis. Primary outcomes for the 1-arm and 2-arm meta-analyzes were change in pre- and post-IPVD P/F ratios and mortality, respectively. Secondary outcomes for the 1-arm meta-analysis were change in pre- and post-IPVD positive end-expiratory pressure (PEEP) and lung compliance, and for the 2-arm meta-analysis the secondary outcomes were need for endotracheal intubation and hospital length of stay (LOS). Results: 13 single arm retrospective studies and 5 case series involving 613 patients were included in the 1-arm meta-analysis. 3 studies involving 640 patients were included in the 2-arm meta-analysis. The pre-IPVD P/F ratios were significantly lower compared to post-IPVD, but there was no significant difference between pre- and post-IPVD PEEP and lung compliance. The mortality rates, need for endotracheal intubation, and hospital LOS were similar between the IPVD and standard therapy groups. Conclusion: Although IPVD may improve oxygenation, our investigation showed no benefits in terms of mortality compared to standard therapy alone. However, randomized controlled trials are warranted to validate our findings. [ABSTRACT FROM AUTHOR]

Systemic steroids are associated with reduced mortality in hypoxic patients with coronavirus disease 2019 (COVID‐19). However, there is no consensus on the doses of steroid therapy in these patients. Several studies showed that pulse dose steroids (PDS) could reduce the progression of COVID‐19 pneumonia. However, data regarding the role of PDS in COVID‐19 is still unclear. Therefore, we performed this meta‐analysis to evaluate the role of PDS in COVID‐19 patients compared to nonpulse steroids (NPDS). Comprehensive literature search of PubMed, Embase, Cochrane Library, and Web of Science databases from inception through February 10, 2022 was performed for all published studies comparing PDS to NPDS therapy to manage hypoxic patients with COVID‐19. Primary outcome was mortality. Secondary outcomes were the need for endotracheal intubation, hospital length of stay (LOS), and adverse events in the form of superimposed infections. A total of 10 observational studies involving 3065 patients (1289 patients received PDS and 1776 received NPDS) were included. The mortality rate was similar between PDS and NPDS groups (risk ratio [RR]: 1.23, 95% confidence interval [CI]: 0.92–1.65, p = 0.16). There were no differences in the need for endotracheal intubation (RR: 0.71, 95%: CI 0.37–1.137, p = 0.31), LOS (mean difference: 1.93 days; 95% CI: −1.46–5.33; p = 0.26), or adverse events (RR: 0.93, 95% CI: 0.56–1.57, p = 0.80) between the two groups. Compared to NPDS, PDS was associated with similar mortality rates, need for endotracheal intubation, LOS, and adverse events. Given the observational nature of the included studies, randomized controlled trials are warranted to validate our findings. [ABSTRACT FROM AUTHOR]

BACKGROUND: Awake prone positioning (APP) has been recently proposed as an adjunctive treatment for non-intubated coronavirus disease 2019 (COVID-19) patients requiring oxygen therapy to improve oxygenation and reduce the risk of intubation. However, the magnitude of the effect of APP on clinical outcomes in these patients remains uncertain. We performed a comparative systematic review and meta-analysis to evaluate the effectiveness of APP to improve the clinical outcomes in non-intubated subjects with COVID-19. METHODS: The primary outcomes were the need for endotracheal intubation and mortality. The secondary outcome was hospital length of stay. Pooled risk ratio (RR) and mean difference with the corresponding 95% CI were obtained by the Mantel-Haenszel method within a random-effect model. RESULTS: A total of 14 studies (5 randomized controlled trials [RCTs] and 9 observational studies) involving 3,324 subjects (1,495 received APP and 1,829 did not) were included. There was a significant reduction in the mortality rate in APP group compared to control (RR 0.68 [95% CI 0.51-0.90]; P=5 .008, I² 5 52%) with no significant effect on intubation (RR 0.85 [95% CI 0.66-1.08]; P = .17, I² 5 63%) or hospital length of stay (mean difference 23.09 d [95% CI-10.14-3.96]; P = .39, I² = 97%). Subgroup analysis of RCTs showed significant reduction in intubation rate (RR 0.83 [95% CI 0.72-0.97]; P = .02, I² 5 0%). CONCLUSIONS: APP has the potential to reduce the in-hospital mortality rate in COVID-19 subjects with hypoxemia without a significant effect on the need for intubation or length of hospital stay. However, there was a significant decrease in the need for intubation on subgroup analysis of RCTs. More large-scale trials with a standardized protocol for prone positioning are needed to better evaluate its effectiveness in this select population. [ABSTRACT FROM AUTHOR]

Recent studies have evaluated and compared the efficacy of normal saline (NS) and lactated Ringer's (LR) in reducing the severity of acute pancreatitis (AP) and improving outcomes such as length of stay, the occurrence of the systemic inflammatory response syndrome (SIRS), ICU admission and mortality. We performed an updated systematic review and meta-analysis of the available studies to assess the impact of these fluids on outcomes secondary to AP. We systematically searched the following databases: PubMed/Medline, Embase, Cochrane, and Web of Science through February 8th, 2021 to include randomized controlled trials (RCTs) and cohort studies. Random effects model using DerSimonian-Laird approach was employed and risk ratios (RR) and mean difference (MD) with 95% confidence interval (CI) were calculated for binary and continuous outcomes, respectively. 6 studies (4 RCTs and 2 cohort studies) with 549 (230 in LR and 319 in NS) were included. The overall mortality (RR: 0.73, CI: 0.31–1.69) and SIRS at 24 h (RR: 0.69, CI: 0.32–1.51) was not significantly different. The overall ICU admission was lower in LR group compared to NS group (RR: 0.43, CI: 0.22–0.84). Subgroup analysis of RCTs demonstrated lower length of hospital stay for LR group compared to NS group (MD: 0.77 days, CI: 1.44 –0.09 days). Our study demonstrated that LR improved outcomes (ICU admission and length of stay) in patients with AP compared to NS. There was no difference in rate of SIRS development and mortality between LR and NS treatments. [ABSTRACT FROM AUTHOR]

Aim of the study: The primary purpose of this study was to assess the association of obstructive sleep apnea (OSA) and non-alcoholic steatohepatitis (NASH) from a large national inpatient sample database. Material and methods: We conducted a retrospective analysis using the Healthcare Cost and Utilization Project-Nationwide Inpatient Sample. OSA and NASH patients were identified using the ICD-10-CM code G47.33 and K75.81. Non-NASH patients (control) were randomly selected and matched by age and gender to each NASH patient in a 4: 1 ratio. Weighted logistic regression models were used to calculate the association between OSA and NASH in addition to different comorbidities. Results: A total of 54,169 participants were included in our analysis; 10,740 cases of NASH were matched to 43,429 controls (non-NASH). NASH was significantly higher in the white population (82.12% vs. 76.64%, p < 0.001). The prevalence of OSA among NASH patients was significantly higher compared to the control group (15.8% vs. 8.9%, adjusted OR: 1.34, 95% CI: 1.14-1.56, p = 0.0003). The prevalence of celiac disease and Crohn's disease was significantly higher in patients with NASH (0.7% vs. 0.2%, p < 0.0002 and 1.28% vs. 0.76%, p < 0.0001). Multiple comorbidities were significantly elevated in the NASH group compared to the non-NASH group, including diabetes mellitus (DM; 36% vs. 17.6%, p < 0.0001), obesity (36.4% vs. 18.2%, p < 0.0001) and metabolic syndrome (0.86% vs. 0.06%, p < 0.0001). The mortality rate was significantly higher in the NASH group (3.8% vs. 2%, p < 0.0001). Conclusions: This is the first study using the ICD-10-CM code with a specific search code for NASH. Our large population database results emphasize that there is a significant association between OSA and NASH. [ABSTRACT FROM AUTHOR]

Introduction: Multiple risk factors of mortality have been identified in patients with COVID-19. Here, we sought to determine the effect of a history of neurological disorder and development of neurological manifestations on mortality in hospitalized patients with COVID-19. Methods: From March 20 to May 20, 2020, hospitalized patients with laboratory confirmed or highly suspected COVID-19 were identified at four hospitals in Ohio. Previous history of neurological disease was classified by severity (major or minor). Neurological manifestations during disease course were also grouped into major and minor manifestations. Encephalopathy, ischemic or hemorrhagic stroke, and seizures were defined as major manifestations, whereas minor neurological manifestations included headache, anosmia, dysgeusia, dizziness or vertigo, and myalgias. Multivariate logistic regression models were used to determine significant predictors of mortality in patients with COVID-19 infection. Results: 574/626 hospitalized patients were eligible for inclusion. Mean age of the 574 patients included in the analysis was 62.8 (SD 17.6), with 298 (51.9%) women. Of the cohort, 240(41.8%) patients had a prior history of neurological disease (HND), of which 204 (35.5%) had a major history of neurological disease (HND). Mortality rates were higher in patients with a major HND (30.9 vs. 15.4%; p = 0.00002), although this was not a significant predictor of death. Major neurological manifestations were recorded in 203/574 (35.4%) patients during disease course. The mortality rate in patients who had major neurological manifestations was 37.4% compared to 11.9% (p = 2 × 10−12) in those who did not. In multivariate analysis, major neurological manifestation (OR 2.1, CI 1.3-3.4; p = 0.002) was a predictor of death. Conclusions: In this retrospective study, history of pre-existing neurological disease in hospitalized COVID-19 patients did not impact mortality; however, development of major neurological manifestations during disease course was found to be an independent predictor of death. Larger studies are needed to validate our findings. [ABSTRACT FROM AUTHOR]

PE is responsible for almost all mortality from VTE, but the impact of obesity on mortality and other outcomes in patients with PE is yet to be explained in detail. Interestingly the mortality in patients with pulmonary embolism was lower in obese patients than in non-obese patients despite getting more thrombolytics and mechanical intubation.
