Purpose: Melanoma brain metastases (MBMs) are a common, lethal complication of metastatic melanoma. Despite improvements in treatments, subsets of MBM patients experience rapid decline, and few prognostic biomarkers have been identified. An improved understanding of the molecular features specifically associated with MBM overall survival (OS) and intracranial progression free survival (PFS) could facilitate the development of more effective clinical management strategies.

We use newly collected data for 16,000 women who applied for Mothers' Pensions, America's first welfare program, to investigate the effect of means-tested cash transfers on lifetime family structure and maternal well-being. In the short term, cash transfers delayed marriage and lowered geographic mobility. In the long run, transfers had no impact on the probability of remarriage, spouse quality, or fertility.

Background: Recent evidence suggests atrial fibrillation (AF) causes cardiomyopathy due to remodeling driven by both irregular rate and rhythm. Atrial fibrillation (AF) ablation in patients with reduced ejection fraction (EF) ≤ 35% has been shown to improve EF and mortality. It is unknown whether the benefits of AF ablation among patients with reduced EF are affected by the degree of pre-ablation rate control.

Ventricular arrhythmias (VA) are a major cause of morbidity and mortality in patients with coronary artery disease (CAD). Current guidelines recommend revascularization of significant CAD to improve survival in patients with ventricular fibrillation (VF), polymorphic ventricular tachycardia (VT), or those who are post-cardiac arrest. However, revascularization is not recommended for CAD patients with suspected scar-mediated monomorphic VT.

Article Synopsis
  • A subgroup of patients with oligometastatic cancer may benefit from local treatment of all cancer lesions to achieve longer disease-free survival, especially when brain metastases are involved.
  • An analysis of 7,000 PET scans identified 106 patients with both extracranial oligometastases and brain metastases, finding that brain involvement significantly impacted disease classification and treatment outcomes.
  • Patients with oligometastasic disease had a median survival of 28 months compared to 10 months for polymetastatic patients, suggesting that brain metastases should not automatically exclude individuals from clinical trials.

We study the lifetime effects of the first and largest American youth employment and training program in the United States-the Civilian Conservation Corps (CCC), 1933-1942. We match newly digitized enrollee records to census, World War II enlistment, Social Security, and death records. We find that longer service in the CCC led to improvements in height, health status, longevity, geographic mobility, and lifetime earnings but did not improve short-term labor market outcomes, including employment and wages.

Article Synopsis
  • Neurosurgical resection can provide significant benefits for breast cancer patients with brain metastases, particularly for those with HER2-positive disease, despite potential delays in systemic therapy.
  • A study analyzed 633 patients with brain metastases from breast cancer to identify outcomes based on breast cancer subtypes, revealing that HER2-positive patients require more subsequent treatments when surgery is omitted.
  • The findings suggest that upfront neurosurgical resection may reduce local recurrence and improve overall treatment outcomes for HER2-positive patients compared to other subtypes, highlighting the need for careful patient selection.

Leptomeningeal metastases (LM) are increasingly becoming recognized as a treatable, yet generally incurable, complication of advanced cancer. As modern cancer therapeutics have prolonged the lives of patients with metastatic cancer, specifically in patients with parenchymal brain metastases, treatment options, and clinical research protocols for patients with LM from solid tumors have similarly evolved to improve survival within specific populations. Recent expansions in clinical investigation, early diagnosis, and drug development have given rise to new unanswered questions.

Background: Many patients with mildly to moderately reduced left ventricular ejection fraction (LVEF) who require permanent pacemaker (PPM) implantation do not have a concurrent indication for implantable cardioverter-defibrillator (ICD) therapy. However, the risk of ventricular tachycardia/ventricular fibrillation (VT/VF) in this population is unknown.

Objective: The aim of this study was to describe the risk of VT/VF after PPM implantation in patients with mildly to moderately reduced LVEF.

Objective: Most of the literature about postmortem sperm retrieval (PMSR) deals with the controversies surrounding ethical and legal aspects, while the optimal time interval between the death and viable sperm acquisition is indefinite. In an attempt to aid fertility specialists, while counseling whether to pursue and adopt PMSR, we aim to explore the maximal time frame from ejaculated sperm acquisition to sperm cryopreservation in different "culture" conditions, observations that might be extrapolated to PMSR requests.

Patients And Methods: Five healthy men with normal semen analysis were enrolled.
