Review Meta Analysis
Efficacy and cardiovascular safety of LAMA in patients with COPD: a systematic review and meta-analysis.
Chronic obstructive pulmonary disease (COPD) is at present the third leading cause of death in the world. Long-acting muscarinic antagonist (LAMA) is widely used as a bronchodilator in patients with COPD. However, there is controversy concerning their cardiovascular safety. ⋯ George's Respiratory Questionnaire (WMD=‒2.50, 95% CI ‒3.32 to ‒1.69, I2=39.8%). Moreover, LAMAs significantly reduced the incidence of exacerbation in patients with COPD (RR=0.85, 95% CI 0.79 to 0.91, I2=69.9%). LAMAs are safe therapy and play a pivotal role in improving lung function, dyspnea, and health status, and reducing the exacerbation in patients with COPD.

Randomized Controlled Trial
A randomized controlled trial on the effect of dietary guidance on the treatment of Henoch-Schonlein purpura in children.
The amino acid-based formulae were extensively added to diet of children for the treatment of Henoch-Schonlein purpura (HSP), and the nutrition and growth situation of children were evaluated after giving new dietary intervention. Patients were randomly divided into restricted diet group (n=30) and dietary guidance group (n=30). Besides, 30 cases with bronchiolitis who had normal diet were selected as the control group. ⋯ However, overall nutrient intake level of the dietary guidance group was higher, basically equal to the recommended intake level. Besides, the actual intake and actual/recommended percentage of nutrients of dietary guidance group were significantly higher than those of restricted diet group (p<0.05). Dietary guidance can improve nutrients and protein intake of children with HSP, and reduce the relapse of rash and incidence of complications.

Observational Study
Nephrosclerosis impacts time trajectory of renal function and outcomes in elderly individuals with chronic kidney disease.
Despite hypertension ranks among the leading causes of chronic kidney disease (CKD), the impact of chronic hypertensive nephropathy, the so-called 'nephrosclerosis' (NS), on CKD progression is often unpredictable, particularly in elderly population. We have conducted a prospective, observational study to define renal function patterns and outcomes in elderly CKD individuals with or without NS. Three hundred four individuals with an already established CKD were categorized according to the etiology of CKD. ⋯ In the whole cohort, the average estimated annual GFR slope was 1.8 mL/min/1.73 m2 eGFR decline was slower in CKD-NS as compared with others (1.4 vs 3.4 mL/min/1.73 m2; p<0.001). The composite renal outcome during follow-up occurred less frequently among elderly with CKD-NS (16/204 vs 14/70; p=0.01, crude HR 0.43, 95% CI 0.22 to 0.85) and was associated at logistic analyses with the etiology of CKD, background cardiovascular disease, total and low density lipoproteins (LDL) cholesterol, and glycemia levels (p value was ranging from 0.01 to 0.05). Despite being highly prevalent in the elderly, NS is associated with a more favorable renal disease course as compared with other conditions.

As of February 2, 2021, the USA has 26,431,799 reported COVID-19 cases with 446,744 deaths. A high mortality rate (15%-40%) was reported among hospitalized patients with COVID-19 during the first wave of the pandemic. However, data regarding variation in COVID-19-related mortality and severity of illness among hospitalized patients with COVID-19 are heterogeneous. ⋯ In-hospital mortality during the second wave was lower (5.9%) compared with the first wave (15.5%). At the last follow-up date, 86.1% were discharged alive from the hospital, 5.9% died and 7.9% were still in the hospital. Multivariate logistic regression showed higher odds of mortality were associated with higher age and elevated lactate dehydrogenase peak.

Observational Study
Biomarker-based score for predicting in-hospital mortality of children admitted to the intensive care unit.
This study aims to establish a new scoring system based on biomarkers for predicting in-hospital mortality of children admitted to the pediatric intensive care unit (PICU). The biomarkers were chosen using the least absolute shrinkage and selection operator (LASSO)-logistic regression in this observational case-control study. The performance of the new predictive model was evaluated by the area under the receiver operating characteristic curve (AUC). ⋯ The calculated ORs showed a trend that higher scores indicated higher risk of death (p value for trend <0.001). In summary, this study develops and validates a totally biomarker-based new score to predict in-hospital mortality for pediatric patients admitted to PICU. More attention and more positive care and treatment should be given to children with a higher score.
