RESUMO
BACKGROUND: Atrial fibrillation (AF) is prevalent, especially in patients with heart failure. Their prevalence increases with age and both conditions are interrelated. Electrocardioversion (ECV) is considered a safe and effective procedure and is among one of the recommended therapies to terminate AF back to normal sinus rhythm. Our study highlights one of the rare complications following ECV. A 71-year-old female with a history of atrial fibrillation underwent electrocardioversion and developed sudden onset of ventricular stunning resulting in refractory cardiogenic shock. She was treated with mechanical cardiac support including IABP and Impella. Both provided minimal support then rapid clinical deterioration happened leading to imminent death. CONCLUSION: Patients with atrial fibrillation and heart failure treated with electrocardioversion might develop refractory cardiogenic shock and death as a complication of this procedure.

BACKGROUND: A safe and pragmatic guide for labelling and delabelling patients with suspected penicillin allergy is mandatory. OBJECTIVE: To compare the performance of 4 penicillin-allergy prediction strategies in a large independent cohort. METHODS: We conducted a retrospective study for subjects presenting between January 2014 and December 2021 at the University Hospital of Montpellier, with a history of hypersensitivity to penicillins. The outcome targeted by the study was a positive penicillin-allergy test. RESULTS: Of the 1,884 participants included, 382 (20.3%) had positive penicillin-allergy tests. The ENDA (European Network on Drug Allergy) and Blumenthal strategies yielded relatively high sensitivities and low specificities and, by design, did not misclassify any positive subjects with severe index reactions. The PEN-FAST <3 score had a negative predictive value of 90% (95% confidence interval [95% CI] 88%-91%), with a sensitivity of 66% (95% CI 62%-71%) and a specificity of 73% (95% CI 71%-75%), and incorrectly delabelled 18 subjects with anaphylaxis and 15 with other severe nonimmediate reactions. For the adapted Chiriac score, the specificity corresponding to 66% sensitivity was 73% (95% CI 70%-75%). Conversely, at a 73% specificity threshold, the sensitivity was 65% (95% CI, 61%-70%). Attempts to improve these prediction algorithms did not substantially enhance performance. CONCLUSIONS: The ENDA and Blumenthal strategies are safe for high-risk subjects, but their delabelling effectiveness is limited, leading to unnecessary avoidance. Conversely, the PEN-FAST and Chiriac scores are performant in delabelling, but more frequently misclassify high-risk subjects with positive penicillin-allergy tests. Selection of the most appropriate tool requires careful consideration of the target population and the desired goal.
RESUMO
Aims: The coronavirus disease 2019 (COVID-19) pandemic has resulted in more than 6 million deaths worldwide. Studies on the impact of obesity on patients hospitalized with COVID-19 pneumonia have been conflicting, with some studies describing worse outcomes in patients with obesity, while other studies reporting no difference in outcomes. Previous studies on obesity and critical illness have described improved outcomes in patients with obesity, termed the "obesity paradox." The study assessed the impact of obesity on the outcomes of COVID-19 hospitalizations, using a nationally representative database. Materials and Methods: ICD-10 code U071 was used to identify all hospitalizations with the principal diagnosis of COVID-19 infection in the National Inpatient Database 2020. ICD-10 codes were used to identify outcomes and comorbidities. Hospitalizations were grouped based on body mass index (BMI). Multivariable logistic regression was used to adjust for demographic characteristics and comorbidities. Results: A total of 56,033 hospitalizations were identified. 48% were male, 49% were white and 22% were black. Patients hospitalized with COVID-19 pneumonia in the setting of obesity and clinically severe obesity were often younger. Adjusted for differences in comorbidities, there was a significant increase in mortality, incidence of mechanical ventilation, shock, and sepsis with increased BMI. The mortality was highest among hospitalizations with BMI ≥60, with an adjusted odds ratio of 2.66 (95% Confidence interval 2.18-3.24) compared to hospitalizations with normal BMI. There were increased odds of mechanical ventilation across all BMI groups above normal, with the odds of mechanical ventilation increasing with increasing BMI. Conclusion: The results show that obesity is independently associated with worse patient outcomes in COVID-19 hospitalizations and is associated with higher in-patient mortality and higher rates of mechanical ventilation. The underlying mechanism of this is unclear, and further studies are needed to investigate the cause of this.
RESUMO
BACKGROUND: Monoclonal Gammopathy of Undetermined Significance (MGUS) is a premalignant plasma cell disorder which despite being clinically silent carries an increased risk of venous thromboembolism (VTE). We conducted a population-based study to investigate the risk of VTE in these patients. METHODS: We utilized the National Inpatient Sample (NIS) for the year 2016 to compare the incidence of acute VTE between patients who carry the diagnosis of MGUS and those who don't. We excluded hospitalizations with age < 18 years and those that had a diagnosed lymphoma, leukemia, solid malignancy, or other plasma cell dyscrasia. We utilized the ICD-10-CM coding system to search the database for codes of VTE, MGUS, and other comorbid conditions. Multivariate logistic regression models were used for comparative analysis adjusting for demographic characteristics and comorbidities. Baseline comorbidities were described as frequencies and proportions for categorical variables and as medians with interquartile ranges for continuous variables. RESULTS: A total of 33,115 weighted hospitalizations were included in the MGUS group. These were compared to 27,418,403 weighted hospitalizations without the diagnosis of MGUS. The MGUS group had higher odds of composite venous thromboembolism (adjusted OR 1.33, 95 % CI 1.22-1.44), deep vein thrombosis (adjusted OR 1.46, 95 % CI 1.29-1.65), and pulmonary embolism (adjusted OR 1.22, 95 % CI 1.09-1.37). CONCLUSION: Patients with MGUS had increased odds of developing acute venous thromboembolism compared to patients with no history of MGUS.

Background: Haemophagocytic lymphohistiocytosis (HLH) is a rare and life-threatening syndrome characterized by an excessive inflammatory response. Limited data exist on adult HLH. Methods: In this national, retrospective cohort study, we analysed data from the US National Inpatient Sample database collected between October 1, 2006 and December 31, 2019. Using the International Classification of Diseases (ICD) codes, we identified all adult patients who were admitted non-electively with the diagnosis of HLH. We described demographic characteristics, triggers, and associated conditions. Trends of diagnosis, treatment, and in-hospital mortality were analysed using joinpoint models. In-hospital mortality rates were compared using multivariable logistic regression models that adjusted for demographic characteristics and associated conditions. Finally, we described resource utilization outcomes including cost of hospitalization and length of stay. Findings: We identified 16,136 non-elective adult HLH admissions. The population pyramid showed a bimodal distribution, with peaks in young adults (16-30 years) and older adults (56-70 years). Joinpoint regression analysis revealed a significant increase in HLH incidence per 100,000 admissions over the study period (Average Annual Percent Change [APC] = 25.3%, p < 0.0001), and no significant change in rates of in-hospital mortality (slope = -0.01; p = 0.95) or administration of in-hospital HLH treatment (slope = 0.46, p = 0.20). The most common associated conditions were malignancy (4953 admissions [30.7%]), infections (3913 admissions [24.3%]), autoimmune conditions (3362 admissions [20.8%]), organ transplant status (639 admissions [4%]), and congenital immunodeficiency syndromes (399 admissions [2.5%]). In-hospital mortality was higher in older adults and males. Furthermore, Congenital immunodeficiency syndromes had the worst in-hospital mortality rate (mortality rate 31.1%, adjusted OR 2.36 [1.56-3.59]), followed by malignancies (mortality rate 28.4%, adjusted OR 1.80 [1.46-2.22]), infections (mortality rate 21.4%, adjusted OR 1.33 [1.10-1.62]), other/no trigger (mortality rate 13.6%, adjusted OR 0.73 [0.58-0.92]), autoimmune (mortality rate 13%, adjusted OR 0.72 [0.57-0.92]), and post-organ transplant status (mortality rate 14.1%, adjusted OR 0.64 [0.43-0.97]). The overall mean length of stay was 14.3 ± 13.9 days, and the mean cost of hospitalization was $54,900 ± 59,800. Interpretation: We provide insight into the burden of adult HLH in the USA. The incidence has been increasing and the outcomes remain dismal. This signifies the growing need for the development of updated diagnosis and treatment protocols that are specific to adult HLH. Funding: None.
RESUMO
Data on clinical outcomes of transcatheter tricuspid valve repair (TTVR) compared with surgical tricuspid valve repair (STVR) in patients with tricuspid valve regurgitation (TVR) remains limited. Data from the national inpatient sample (2016-2020) and propensity-score matched (PSM) analysis was utilized to determine adjusted odds ratio (aOR) of inpatient mortality and major clinical outcomes of TTVR compated with STVR in patients with TVR. A total of 37,115 patients with TVR were included: 1830 (4.9%) and 35,285 (95.1%) underwent TTVR and STVR, respectively. After PSM, there was no statistically significant difference in baseline characteristics and medical comorbidities between both groups. Compared with STVR, TTVR was associated with lower inpatient mortality (aOR 0.43 [0.31-0.59], P < 0.01), cardiovascular complications (aOR 0.47 [0.3-0.45], P < 0.01), hemodynamic complications (aOR 0.47 [0.4-0.55], P < 0.01), infectious complications (aOR 0.44 [0.34-0.57], P < 0.01), renal complications (aOR 0.56 [0.45-0.64], P < 0.01), and need for blood transfusion. There was no statistically significant difference in odds of major bleeding events (aOR 0.92 [0.64-1.45], P 0.84). Also, TTVR was associated with less mean length of stay (7 days vs 15 days, P < 0.01) and less cost of hospitalization ($59,921 vs $89,618) compared with STVR. There was an increase in the utility of TTVR associated with a decrease in the utility of STVR from 2016 to 2020 (P < 0.01). Our study showed that compared with STVR, TTVR was associated with lower inpatient mortality and clinical events. Nevertheless, further studies are needed to investigate the difference in outcomes between both procedures.
