An Analysis of Major Causes of Surgical Failure Using Bähren System in Intraoperative Venography During Varicocelectomy.
In young patients with varicocele, preservation of the internal spermatic artery may be advantageous for catch-up growth, but it may also increase the likelihood of treatment failure. Intraoperative venography reduces the likelihood that unsealed veins will remain after varicocelectomy. We analyzed the characteristics of remnant veins visualized through intraoperative venography to investigate the cause of surgical failure in artery-sparing varicocelectomy (ASV). ⋯ Remnant collateral veins of the internal spermatic vein (ISV) (Bahren type 3) are the most common cause of failure in ASV. In a few patients, an external spermatic vein merges with the ISV at a higher level (Bahren type 4) and is unidentifiable without venography.

Delays in Intracerebral Hemorrhage Management Is Associated with Hematoma Expansion and Worse Outcomes: Changes in COVID-19 Era.
The coronavirus disease 2019 (COVID-19) pandemic disrupted the emergency medical care system worldwide. We analyzed the changes in the management of intracerebral hemorrhage (ICH) and compared the pre-COVID-19 and COVID-19 eras. ⋯ During the COVID-19 era, delays in management of ICH was associated with hematoma expansion and worse outcomes.

Nationwide Social Distancing and the Epidemiology of Severe Acute Respiratory Infections.
Nonpharmaceutical interventions (e.g., social distancing) are recommended to prevent the spread of respiratory viruses. However, few epidemiological studies have assessed whether social distancing in actual settings reduces the disease burden of severe acute respiratory infections (SARIs) in the general population. Accordingly, we aimed to assess associations between nationwide social distancing for coronavirus disease 2019 (COVID-19) and non-COVID-19 SARIs. ⋯ However, seasonality was not observed since social distancing was initiated. Our sentinel surveillance data demonstrated a remarkable reduction in SARI disease burden and a change in seasonality following the implementation of nationwide social distancing. Accordingly, we suggest that social distancing could be effective in forthcoming seasonal epidemics of non-COVID19 origin, although the impact thereof on other aspects of society needs to be carefully considered.

Observational StudyClinical Implication of Hypoxic Liver Injury for Predicting Hypoxic Hepatitis and In-Hospital Mortality in ST Elevation Myocardial Infarction Patients.
In this study, we aimed to determine the value of hypoxic liver injury (HLI) in the emergency room (ER) for predicting hypoxic hepatitis (HH) and in-hospital mortality in ST elevation myocardial infarction (STEMI) patients. ⋯ Among STEMI patients, HLI in the ER is a significant predictor for the development of HH and mortality during hospitalization (INTERSTELLAR ClinicalTrials.gov number, NCT02800421).

Modified Procedures for ALPPS Based on a Risk-Reduced Strategy: Paralleled Clinical Evaluation at Multiple Institutions.
We compared the clinical outcomes of modified procedures for associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) based on a risk-reduced strategy with those of classic ALPPS procedures in treating large liver carcinoma. ⋯ Modified ALPPS procedures could be safely applied to provide long-term survival for patients with liver cirrhosis without sufficient FLR.
