Review Meta Analysis
Efficacy and safety of medications for osteoporosis in kidney transplant recipients or patients with chronic kidney disease: a meta-analysis.
This study conducted a meta-analysis to analyze the efficacy and safety of osteoporosis medications in kidney transplant recipients and patients with chronic kidney disease (CKD). PubMed, Embase, the Cochrane Central Register of Controlled Trials were searched from the date of their inception through October 21, 2022. We performed a meta-analysis of the efficacy and safety of osteoporosis medications in adult patients with stage 3-5 CKD or kidney transplant recipients enrolled in randomized clinical trials (RCTs). ⋯ Thus, there is no evidence that these medications reduce the risk of fracture, and their effect on BMD and fracture remains unproven. These medications may increase the incidence of adverse events and their safety needs to be further evaluated. Therefore, we cannot draw a definitive conclusion about the efficacy and safety of osteoporosis medications in the above group of patients.

Association between nonalcoholic fatty liver disease and atrial fibrillation and other clinical outcomes: a meta-analysis.
The association between nonalcoholic fatty liver disease (NAFLD) with cardiovascular and cerebrovascular outcomes, as well as their clinical impact, has yet to be established in the literature. This meta-analysis aims to evaluate the association between the NAFLD patients and the risk of atrial fibrillation (AF), heart failure (HF), stroke, cardiovascular mortality (CVM), and revascularization incidence. We performed a systematic literature search using PubMed, Embase, Scopus, and Cochrane libraries for relevant articles from inception until August 2022. ⋯ The likelihood of AF (risk ratio (RR), 1.42 (95% CI 1.19, 1.68), p < 0.001), HF (RR, 1.43(95% CI 1.03, 2.00), p < 0.001), stroke (RR, 1.26(95% CI 1.16, 1.36), p < 0.001), revascularization (RR, 4.06(95% CI 1.44, 11.46), p = 0.01), and CVM (RR, 3.10(95% CI 1.43, 6.73), p < 0.001) was significantly higher in the NAFLD patients group compared to that of the non-NAFLD group. However, all-cause mortality was comparable between both the groups of patients (RR, 1.30 (95% CI 0.63, 2.67), p = 0.48). In conclusion, the patients with NAFLD are at increased risk of AF, HF, and CVM.

Insulin and its secretagogues are essential for some patients with type 2 diabetes (T2D) to maintain good glycemic control (GC), but severe hypoglycemia (SH) is a concern. This network meta-analysis aimed to find optimal glucose-lowering drug treatment regimens in terms of GC and SH in T2D patients. MEDLINE and EMBASE were used to identify trials that compared two or more treatments including insulins and/or sulfonylurea or glinides and that examined both GC and SH. ⋯ Cluster analysis indicated that premixed insulin plus glucagon-like peptide-1 receptor agonist (Mix-ins + GLP1) belonged to the high-efficacy category for GC and glinide plus thiazolidinedione (glinide + TZD) belonged to the relatively high-efficacy category for GC among several high-safety categories regarding SH. In T2D patients, clinicians should consider appropriate combinations of non-insulin glucose-lowering agents (especially glinide + TZD) for reducing SH risk before switching to insulin therapies. If switching, they should be willing to add non-insulin glucose-lowering agents (especially, Mix-ins + GLP1) to insulins to further improve GC.

Meta Analysis
Comparison of outcome among type 2 vs type 1 myocardial infarction: a systematic review and meta-analysis.
To date, there were limited studies available on myocardial infarction (MI), and consequently, the outcomes of patients with type 1 myocardial infarction (T1MI) compared to type 2 myocardial infarction (T2MI) remained inconclusive. We aimed to compare the outcomes of T1MI and T2MI patients in terms of mortality and adverse cardiovascular outcomes. We performed a systematic literature search on PubMed, Embase, and Scopus for relevant articles from inception until March 20, 2022. 341,049 patients had T1MI, while the remaining 67,537 patients had T2MI. ⋯ There was no significant difference in terms of 30-day mortality (OR 0.58, 95% CI 0.25-1.36, p = 0.21), cardiovascular mortality (OR 0.95, 95% CI 0.68-1.32, p = 0.74), all-cause readmission (OR 0.84, 95% CI 0.62-1.14, p = 0.26), and readmission due to MI (OR 1.22, 95% CI 0.66-2.27, p = 0.53) between both groups. Patients with T1MI had favorable outcomes in terms of mortality and MACE compared to that of T2MI patients. Further studies should aim at determining the optimal management strategy for these high-risk patients for better patient outcomes.

Review Meta Analysis
Review of existing evidence demonstrates that methotrexate does not cause liver fibrosis.
It has long been believed that methotrexate in therapeutic doses causes progressive liver injury resulting in advanced fibrosis and cirrhosis. Historically, this was a common indication for serial liver biopsy. However, new evidence suggests that methotrexate may not be a direct cause of liver injury; rather the injury and fibrosis attributed to methotrexate may be mediated by other mechanisms, specifically non-alcoholic fatty liver disease. ⋯ Individual studies reported fibrosis related to confounding factors such as diabetes, obesity, pre-existing chronic liver disease but not methotrexate exposure. In conclusion, existing evidence demonstrates that advanced liver fibrosis and cirrhosis previously attributed to methotrexate are in fact caused by metabolic liver disease or other chronic liver diseases, but not by methotrexate itself. This observation should direct the care of patients treated with long-term methotrexate.
