Shrinking Lung Syndrome in a Young Female: A Rare Pulmonary Manifestation of Systemic Lupus Erythematosus

Shrinking lung syndrome (SLS) is a rare pulmonary complication of autoimmune conditions. It has been sparsely described in the literature and its pathophysiology remains unclear. SLS is typically reported in patients with a history of systemic lupus erythematosus (SLE) who present with shortness of breath and chest pain associated with breathing. Chest imaging demonstrates no alveolar, interstitial, or pleural abnormalities. Pulmonary function tests (PFTs) are characterized by a restrictive pattern with reduced lung volumes. SLS is a diagnosis of exclusion and there are no validated criteria for the diagnosis. Evaluation requires extensive testing to rule out alternative causes of dyspnea and pleuritic chest pain. In this report, we present a case of SLS in a young African American woman

Compression wraps as adjuvant therapy in the management of acute systolic heart failure

BACKGROUND: Guidelines recommend targeting decongestion in management of decompensated HF, with lower extremity edema often serving as the clinical target. LECW are seldom used in the acute setting, with a paucity of data on efficacy in HF, despite serving as a cornerstone of chronic lymphedema management. PRIMARY OBJECTIVE: Study the efficacy and safety of LECW in acute decompensated HF. METHODS: Open-label, randomized, parallel-group clinical trial. PRIMARY OUTCOMES: Days on intravenous (IV) diuretic therapy, total hospital length of stay (LOS), and 30-day all-cause readmission. RESULTS: 32 patients were enrolled, with 29 patients completing the study. Enrollment was suspended due to the COVID-19 pandemic. Overall LOS was shorter in the intervention group (3.5 vs 6 days, p = 0.05), with no significant difference in total days on IV diuresis or 30-day readmission rate with use of LECW. Fewer patients required continuous diuretic infusion after treatment with LECW (0 vs 7 patients, p = 0.027). The intervention group scored significantly better on the MLWHF (55.5 vs 65, p = 0.021), including both the physical and emotional dimension scores. No adverse events were reported with use of LECW, including a significantly lower incidence of AKI (1 vs 13 patients, p = 0.005). CONCLUSION: The use of LECW resulted in reduced hospital LOS compared to standard therapy, with no difference in days of IV diuresis administration or 30-day readmission. Treatment with LECW also resulted in less continuous IV diuretic therapy, fewer incidence of AKI, and improved quality of life. Trends toward less escalation of diuresis, and greater reduction in edema were also observed

Perioperative management of anticoagulation

Periprocedural management of the anticoagulated patient can be as easy as continuing warfarin for a low bleeding risk procedure, holding a direct oral anticoagulant for 1 day prior and resuming 1 day later or as complex as emergent reversal with prothrombin complex concentrate, idarucizumab, or andexanet alfa. Patient-specific factors for thromboembolic risk and procedural bleeding risk determine timing of anticoagulation hold prior to and resumption after invasive procedures. Clinical trials and management studies in recent years have helped inform our approach to these patients, but much of the guidance is still based on expert consensus

Predicting Right Ventricular Failure Following Left Ventricular Assist Device Support: A Derivation-Validation Multicenter Risk Score

Purpose: Despite several models predicting right ventricular failure (RVF) after durable left ventricular assist device (LVAD) support, poor performance when externally validated has limited their widespread use. We sought to derive a predictive model for RVF after LVAD implantation, and ascertain its performance in an independent cohort. Methods: End-stage heart failure (HF) patients requiring continuous-flow LVAD were prospectively enrolled at one US program (n=477, derivation cohort), with two other US medical centers forming the validation cohort (n=321). The primary outcome was RVF incidence, defined as the need for right ventricular assist device or inotropes for \u3e14 days. Multivariable logistic regression in the derivation set yielded a RVF predictive model, which was subsequently applied to the validation cohort, and a risk score was ultimately developed. Results: Derivation cohort included patients less likely to be African-Americans (7% vs 37%; p\u3c0.001), Hispanics (7% vs 30%; p\u3c0.001), have a remote history of hypertension (49% vs 60%; p=0.002) or be bridged with short-term MCS (8% vs 16%; p=0.001), compared to the validation set. RVF incidence was 16% in the derivation and 36% in the validation cohort (p\u3c0.001). Multivariable analysis identified 7 variables (Figure) as predictive of RVF, with the model achieving a C statistic of 0.734 (95% CI=0.674-0.794) in the derivation and 0.709 (95% CI=0.651-0.767) in the heterogeneous validation cohort. Patients were stratified into 3 RVF risk groups (all comparisons; p\u3c0.001) (Figure). Conclusion: We propose a novel scoring system to predict post-LVAD RVF, achieving high discriminative performance in distinct, heterogeneous LVAD cohorts
