Meta Analysis
Palliative radiotherapy for gastric cancer: Is there a dose relationship between bleeding response and radiotherapy?
The aim of this study was to evaluate whether there is a relationship between bleeding response and radiotherapy dose to palliate patients with local recurrence or progression of gastric cancer (GC). To this end, we conducted a systematic review and meta-analysis of observational studies that evaluated the bleeding response in patients with GC with local recurrence or progression. A meta-regression analysis between biological effective dose (BED) and bleeding response was performed, as was subgroup analysis to evaluate the outcome by BED level and radiotherapy (RT) technique. ⋯ Palliative RT is effective at controlling bleeding due to local recurrence/progression from GC. Our findings reveal a relationship between BR and BED. BED <30 Gy 10 should not be recommended, and 3DRT should be indicated instead in order to improve the result.

Coronavirus disease (COVID-19) rapidly progresses to severe acute respiratory syndrome. This review aimed at collating available data on COVID-19 infection in solid organ transplantation (SOT) patients. We performed a systematic review of SOT patients infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). ⋯ Among all transplant patients, COVID-19 had the highest fatality rate in patients older than 60 years : LT, 62.5% vs 12.5% (p=0.006); KT 44.44% vs 0 (p=0.039); and SOT, 52.94% vs 4.54% (p=0.001). This study presents a novel description of COVID-19 in abdominal SOT recipients. Furthermore, we alert medical professionals to the higher fatality risk in patients older than 60 years. (PROSPERO, registration number=CRD42020181299).

The coronavirus disease 2019 (COVID-19) is an emerging pandemic challenge. Acute respiratory distress syndrome (ARDS) in COVID-19 is characterized by a severe cytokine storm. Patients undergoing glucocorticoid (GC) replacement therapy for adrenal insufficiency (AI) represent a highly vulnerable group that could develop severe complications due to the SARS-CoV-2 infection. ⋯ Adrenal crisis is a medical emergency and an important cause of death. Once patients with AI present symptoms of COVID-19, the dose of GC replacement therapy should be immediately doubled. In the presence of any emergency warning signs or inability to administer oral GC doses, we recommend that patients should immediately seek Emergency services to evaluate COVID-19 symptoms and receive 100 mg hydrocortisone by intravenous injection, followed by 50 mg hydrocortisone intravenously every 6 h or 200 mg/day by continuous intravenous infusion.

We aimed to estimate the overall survival (OS) and conditional survival (CS) in patients diagnosed with oral and oropharyngeal squamous cell carcinoma (SCC) and to determine their survival trends. ⋯ Survival across the two time periods remained stable for oral SCC but showed a significant increase for oropharyngeal SCC, possibly because of improvements in the patients' response to radiotherapy, such as intensity-modulated radiation therapy, and the use of more accurate diagnostic imaging approaches.
