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.

Acyclovir (ACV)-associated encephalopathy is related to an increase in plasma levels of 9-carboxymethoxymethylguanine, an ACV metabolite, and is often reported in patients with renal dysfunction. We report a case of ACV-associated encephalopathy with rapid progression of renal dysfunction after oral administration of valacyclovir (VACV) and review literature of previous ACV-associated encephalopathy cases. ⋯ Worsening of renal function and encephalopathy should be a focus when using VACV or ACV, regardless of age and original renal function. Acute kidney injury and ACV-associated encephalopathy may particularly occur in the elderly even when renal function is normal. Therefore, regular monitoring of renal function and consciousness is necessary during VACV treatment.

Concurrent chemoradiotherapy is widely utilised as a standardized primary method of treatment for patients with advanced nasopharyngeal carcinoma (NPC). However, the combination of concurrent chemoradiotherapy and adjuvant chemotherapy for treating NPC patients remain unclear. Therefore, this study attempts to elucidate the efficiency and safety of concurrent chemoradiotherapy combined with adjuvant chemotherapy (gemcitabine plus cisplatin versus 5-fluorouracil plus cisplatin) for treating patients with NPC. ⋯ The current research evaluates the clinical efficiency and safety of utilising concurrent chemoradiotherapy combined with adjuvant chemotherapy as a therapeutic strategy to treat advanced NPC patients. The work done in this study will provide a clinical basis for concurrent chemoradiotherapy in combination with adjuvant chemotherapy for treating advanced NPC.

Multicenter Study
No evidence of tocilizumab treatment efficacy for severe to critical SARS-CoV2 infected patients: Results from a retrospective controlled multicenter study.
To assess tocilizumab (TCZ) efficacy associated to standard of care (SOC) compared to SOC alone in severe coronavirus associated disease 2019 (COVID-19) patients. In a matched case-control study from 3 French Hospital COVID-19 Departments, 27 patients with severe COVID-19 treated with TCZ and SOC were matched for baseline epidemiological and clinical features and compared to 27 severe COVID-19 patients treated with SOC alone. Baseline characteristics of the study population were comparable between groups. ⋯ Age (OR = 1.15; 95%CI = 1.04-1.3; P = .008) and age over 72 years (OR) = 14.85; 95%CI = 2.7-80; P = .002) were independently associated with mortality. TCZ in addition to SOC for severe COVID-19 patients did not reduce mortality, subsequent need for invasive mechanical ventilation nor did it shorten the time of oxygen support, despite better control of the inflammatory response. More powerful and randomized controlled trials are warranted to determine if TCZ is effective in the management of COVID-19.

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.
