Multicenter Study
Is retinal vein occlusion associated with depression symptoms?: A nationwide cohort study.
Retinal vessels share similar anatomical and physiological characteristics with the cerebral microvasculature, and abnormal cerebral blood flow is reportedly associated with depressive disorder. However, there is limited evidence regarding the relationship between depression and the risk of retinal vein occlusion (RVO). This study aimed to investigate the association between depression and the prospective risk of RVO using nationally representative longitudinal data. ⋯ After all confounding variables were adjusted, the hazard ratio of RVO in the depression group with or without recurrence was 1.2 (95% confidence interval [CI]: 1.076-1.338) and 1.087 (95% CI: 1.012-1.167), respectively, relative to the comparison group. This is the first nationwide, population-based, epidemiologic study that evaluated the association between depression and the risk of RVO development. The presence of depression was significantly associated with increased risks of RVO, and the recurrence of depression showed a higher RVO incidence probability.

Review Meta Analysis
Iron therapy in iron-deficiency patients with heart failure with preserved ejection fraction: A protocol for meta-analysis.
Nearly half of patients with heart failure (HF) have preserved ejection fraction (EF) and the mortality and morbidity of patients with HF with preserved EF (HFpEF) are high. However, there is no established therapy to improve survival in these patients. HFpEF patients are often elderly and their primary chronic symptom is severe exercise intolerance. Thus, improvement of exercise capacity presents another important clinical outcome in HFpEF patients. Iron deficiency is common in HF patients, and the presence of iron deficiency, regardless of concomitant anemia, is associated with worse symptoms, impaired exercise capacity, and higher mortality and hospitalization in these patients. Several meta-analyses of randomized controlled trials reported that iron administration improved HF symptoms, exercise capacity, and clinical outcomes in iron-deficiency patients with HF with reduced EF. However, there is insufficient evidence as to the effect of iron administration in iron-deficiency HFpEF patients. ⋯ PROSPERO CRD42020205297.

Review Meta Analysis
A meta-analysis of the utility of transabdominal ultrasound for evaluation of gastric cancer.
Clinical discovery/staging of gastric cancer (GC) is crucial in designing the treatment strategies and largely decides GC patients' survival. Endoscopic ultrasonography (EUS) and computed tomography (CT) are 2 useful GC diagnosis tools. High doses of radiation associated with CT make its use limited, while the process of EUS is stressful, time-consuming, and challenging. Transabdominal ultrasound (TAUS) is a promising candidate to address these shortcomings. This study aimed to meta-analyze the diagnostic accuracy and sensitivity of TAUS in discriminating between advanced and early GCs, as well as compare its utility with other imaging techniques.Methods: Literature searches were conducted using PubMed, Web of Science, Embase, and Cochrane Library databases up to 2019. Data were analyzed using RevMan software (Cochrane Collaboration, Oxford, UK), and pooled estimates of accuracy, sensitivity, and other features were acquired. Seven papers were eventually selected for meta-analysis. ⋯ TAUS is more accurate and sensitive in diagnosing advanced GC compared to early GC. More features of advanced GC are required to improve the recognition ability. At least, TAUS can be considered as a complementary imaging diagnostic tool to CT and EUS.

The function of Angipoietin-2 (Agn2) in osteosarcoma has not been fully explored and exists controversial. Therefore, we conducted a meta-analysis to investigate the role of Agn2 in the prognosis of osteosarcoma. In addition, bioinformatics analysis was carried out to reveal the mechanism and related pathways of Agn2 in osteosarcoma. ⋯ DOI 10.17605/OSF.IO/GWQ53.

Multicenter Study
Differences between dedicated and not dedicated hospice physicians in symptoms and signs improvement among advanced cancer patients.
The hospice and palliative care can improve the symptoms and signs of terminal cancer patients. The purposes of this study are how to improve terminally ill cancer patients' symptoms and signs and how the dedicated palliative care service effects on these improvements. From January 2017 to March 2019, among 919 terminally ill cancer patients admitted to the palliative care units in 11 hospitals of South Korea, we analyzed 334 patients with prospective cohort method and categorized them into non-dedicated hospice care group of 234 and dedicated hospice care group of 100. ⋯ Compared to non-dedicated care group, the odds ratio for more than 2 symptoms or signs was 1.78 (95% confidence interval, 1.05-3.02) in the dedicated care group after adjusting confounding variables. In conclusion, terminally ill cancer patients who received palliative or hospice service showed significant improvement in symptoms and signs. And, family doctors (dedicated hospice physician group) performed better than oncologists (non-dedicated physician group).
