Case Reports
Transapical off-pump mitral valve repair following prior mitral valve surgery: A case report.
Redo surgeries after mitral valve repair are technically demanding. Procedures applying the NeoChord device (NeoChord Inc, St. Louis Park, MN) have proven to be safe and feasible in selected patients requiring mitral valve repair due to a leaflet prolapse or flail. However, its use for redo procedures after conventional surgical repair has not been well established yet. ⋯ As redo surgery after minimally invasive mitral valve repair is challenging, the NeoChord device represents a novel treatment option that does not require cardiopulmonary bypass.

Comparative Study
The efficacy and safety of beta-blockers versus cyanoacrylate injection for gastric variceal bleeding: A protocol for systematic review and meta-analysis.
The benefit of beta-blockers for secondary prophylaxis of gastric variceal bleeding has limited evidence. Therefore, a systematic review and meta-analysis was conducted to systematically analyze and compare the effect of beta-blockers versus cyanoacrylate injection for patients with gastric variceal bleeding. ⋯ 10.17605/OSF.IO/CPV9T.

Skin melanoma remains a highly prevalent and yet deadly form of cancer, with the exact degree of melanoma-associated mortality being strongly dependent upon the local tumor microenvironment. The exact composition of stromal and immune cells within this microenvironmental region has the potential to profoundly impact melanoma progression and prognosis. As such, the present study was designed with the goal of clarifying the predictive relevance of stromal and immune cell-related genes in melanoma patients through comprehensive bioinformatics analyses. ⋯ This 10-gene signature effectively separated melanoma patients into low- and high-risk groups based upon their survival. These low- and high-risk groups also exhibited distinct immune statuses and differing degrees of immune cell infiltration. In conclusion, our results offer novel insights into a number of microenvironment-associated genes that impact survival outcomes in melanoma patients, potentially highlighting these genes as viable therapeutic targets.

Observational Study
Sex-related differences in bone metabolism in osteoporosis observational study.
Although the incidence is lower in men than women, osteoporosis remains a significant health issue in men as it may give rise to severe complications if not managed appropriately. As men and women show different biological and social backgrounds, we retrospectively evaluated the differences in the bone metabolism between men and women using bone biomarkers. Bone mineral density (BMD) was determined in all patients using dual-energy X-ray absorptiometry (DXA) and analyzing various bone biomarkers such as carboxyl-terminal collagen crosslinks (CTX), osteocalcin (OCT), and alkaline phosphatase (ALP). ⋯ Levels of biomarkers of bone formation and absorption were increased in the osteoporosis group. However, men showed lower increases in bone formation biomarkers than did women, indicating that the rate of bone formation relative to bone absorption did not increase in men compared with that in women. Therefore, we suggest that men and women have different bone metabolism in old age.

Meta Analysis
Psychosocial risk factors associated with esophageal cancer in Chinese cohort: A systematic review and meta-analysis.
Previous studies were controversial about the role of psychosocial factors in the pathogenesis of esophageal cancer (EC). This study aimed to systematically evaluate the effect size of psychosocial risk factors for EC in Chinese cohort. A literature search was conducted in both English and Chinese databases, and odds ratios (OR) with the corresponding 95% confidence intervals (CI) were pooled using a random-effects model.28 studies were identified with a total of 6951 EC cases and 7469 controls. ⋯ A lower EC risk was found in the individuals with good interpersonal relationship (OR: 0.35, 95% CI: 0.17-0.70) and outgoing personality (OR: 0.39, 95% CI: 0.19-0.78). This meta-analysis suggested a potential association between psychosocial factors and EC risk. For the individuals with psychosocial risk factors, physicians should pay more attention to EC screening.
