RESUMEN
INTRODUCTION: Most patients undergoing a left atrial appendage occlusion (LAAO) procedure are admitted for overnight observation. A same-day discharge strategy offers the opportunity to improve resource utilization without compromising patient safety. We compared the patient safety outcomes and post-discharge complications between same-day discharge versus hospital admission (HA) (>1 day) in patients undergoing LAAO procedure. METHODS: A systematic search of MEDLINE and Embase was conducted. Outcomes of interest included peri-procedural complications, re-admissions, discharge complications including major bleeding and vascular complications, ischemic stroke, all-cause mortality, and peri-device leak >5 mm. Mantel-Haenszel risk ratios (RRs) with 95% CIs were calculated. RESULTS: A total of seven observational studies met the inclusion criteria. There was no statistically significant difference between same-day discharge versus HA regarding readmission (RR: 0.61; 95% confidence interval [CI]: [0.29-1.31]; p = .21), ischemic stroke after discharge (RR: 1.16; 95% CI: [0.49-2.73]), peri-device leak >5 mm (RR: 1.27; 95% CI: [0.42-3.85], and all-cause mortality (RR: 0.60; 95% CI: [0.36-1.02]). The same-day discharge study group had significantly lower major bleeding or vascular complications (RR: 0.71; 95% CI: [0.54-0.94]). CONCLUSIONS: This meta-analysis of seven observational studies showed no significant difference in patient safety outcomes and post-discharge complications between same-day discharge versus HA. These findings provide a solid basis to perform a randomized control trial to eliminate any potential confounders.

BACKGROUND: Multiple randomized controlled trials (RCTs) have compared the success of antero-lateral vs. antero-posterior electrode position for cardioversion of atrial fibrillation (AF). However, due to small sample size and conflicting results of these RCTs, the optimal electrode positioning for successful cardioversion remains uncertain. METHODS: A systematic search of MEDLINE and EMBASE was conducted. Outcomes of interest included overall success of cardioversion with restoration of sinus rhythm, 1st shock success, 2nd shock success, mean shock energy required for successful cardioversion, mean number of shocks required for successful cardioversion, success of cardioversion at high energy (> 150 J) and success of cardioversion at low energy (< 150 J). Mantel-Haenszel risk ratios (RR) with 95% confidence intervals were calculated using random-effects model. RESULTS: A total of 14 RCTs comprising 2445 patients were included. There was no statistically significant difference between two cardioversion approaches in the overall success of cardioversion (RR 1.02; 95% CI [0.97-1.06]; p = 0.43), first shock success (RR 1.14; 95% CI [0.99-1.32]), second shock success (RR 1.08; 95% CI [0.94-1.23]), mean shock energy required (mean difference 6.49; 95% CI [-17.33-30.31], success at high energy > 150 J (RR 1.02; 95% CI [0.92-1.14] and success at low energy < 150 J (RR 1.09; 95% CI [0.97-1.22]). CONCLUSIONS: This meta-analysis of RCTs shows no significant difference in the success of cardioversion between antero-lateral vs. antero-posterior electrode position for cardioversion of AF. Large well-conducted and adequately powered randomized clinical trials are needed to definitively address this question.

Despite recent developments, evaluation of peripheral pulmonary lesions (PPL) remains clinically challenging, and the diagnostic yield of many image-guided and bronchoscopy methods is still poor. Furthermore, complications from such procedures, such as pneumothorax and airway hemorrhage, are a major concern. Recently launched robotic-assisted bronchoscopy (RAB) platforms are still in the early exploration stage and may provide another tool for achieving PPL evaluation. We present our experience here as a retrospective cohort study describing the 12-month diagnostic yield with the shape-sensing Ion™ platform for minimally invasive peripheral lung biopsy. The study describes forty-two patients undergoing shape sensing robotic-assisted bronchoscopy (ssRAB) at our institute. The early performance trend reveals a lesion localization of 100% and an overall 12-month diagnostic yield of 88.10%. The diagnostic yield for lesions less than 20 mm was 76% and for lesions greater than 20 mm was 100%. We also report our complication profile; we noted no pneumothoraces, excessive bleeding, or post-operative complications. In comparison to traditional bronchoscopy and image-guided modalities, our experience shows that ssRAB can be utilized successfully to travel to extremely small peripheral lesions with a higher diagnostic yield and better safety profile.
RESUMEN
The second hit hypothesis in pulmonary hypertension refers to the development of pulmonary vascular disease in individuals at risk, after an additional exposure or "hit" to factors with potential injury to the pulmonary circulation, such as drugs or toxins. We here present a case of severe pulmonary hypertension diagnosed during the third trimester of pregnancy, in a patient with familial history of pulmonary hypertension, found to have a heterozygous mutation in the BMPR2 gene, who also had chronic exposure to prescription amphetamines. We hypothesize that exposure to prescription amphetamines could act as a second hit of pulmonary vascular injury in individuals at risk of pulmonary vascular disease.
RESUMEN
CASE PRESENTATION: A 30-year-old man with a history of childhood asthma, a 15-pack-year smoking history, and methamphetamine abuse was intubated and started on mechanical ventilation because of acute hypoxic respiratory failure after experiencing progressive dyspnea and a nonproductive cough over the previous year. During the previous 3 months, he had multiple clinic visits, with chest radiographs showing diffuse, bilateral, reticulonodular opacities and small bilateral pleural effusions and was treated for community-acquired pneumonia. Testing for COVID pneumonia was negative, and he failed to respond to antimicrobial therapy. Physical examination on admission showed diffuse fine crackles bilaterally on lung auscultation. Admission laboratory test results were unremarkable.
