Potential similarities in gut microbiota composition between autism spectrum disorder and neurotypical siblings: Insights from a comprehensive meta-analysis.
Previous studies have explored the differences in gut microbiota (GM) between individuals with autism spectrum disorder (ASD) and neurotypical controls. However, factors such as diet, lifestyle, and environmental exposure influence GM, leading to significant variability, even among neurotypical individuals. Comparing the GM of ASD individuals with neurotypical siblings, who share similar genes and living conditions, may offer better insights into the GM mechanisms associated with ASD. Therefore, this study aims to analyze the GM composition in ASD by comparing it to that of neurotypical siblings, potentially identifying microbiota that influence ASD. ⋯ GM composition in ASD individuals closely resembles that of neurotypical siblings, with only a few unstable differences. This suggests that other crucial bacteria or certain interacting environmental factors play a role. Further studies are needed to gather stronger evidence to uncover the differences in GM and their mechanisms in ASD people.

The safety and efficacy of stem cell therapy for diabetic peripheral neuropathy in animal studies: A systematic review and meta-analysis.
Diabetic peripheral neuropathy (DPN) is the most common form of diabetic neuropathy, representing 75% of cases and posing a substantial public health challenge. Emerging evidence from animal studies indicates that stem cell therapy holds significant promise as a potential treatment for diabetic neuropathy. Nevertheless, a comprehensive evaluation of the safety and efficacy of stem cell therapy for DPN in animal studies remains outstanding. ⋯ The stem cell subgroup analysis showed that dental pulp stem cells had the greatest effects across all parameters, while bone marrow mononuclear cells had strong biochemical responses. Stem cell therapy demonstrates promising efficacy in ameliorating neuropathic symptoms in DPN animal models. Human patient studies and targeted treatment procedures for specific neuropathic disorders are advocated to improve therapeutic outcomes.

Risk factors for delirium in patients with COVID-19: A systematic review and meta-analysis.
Delirium is one of the serious neurological complications of Coronavirus Disease 2019 (COVID-19) and is associated with significant morbidity and mortality in patients with COVID-19, especially in older patients. There is currently no meta-analysis of risk factors for delirium in patients with COVID-19. This study aimed to identify potential risk factors for delirium in patients with COVID-19 through a meta-analysis of observational clinical studies. ⋯ Notably, the administration of hydrocortisone and azithromycin, among other specific medications designated for COVID-19, exhibited a potential to be positively associated with the incidence of delirium in patients afflicted with COVID-19. In conclusion, the present study identified potential predisposing and precipitating factors linked with delirium in COVID-19 patients. It is anticipated that these results will have a considerable impact on the management and treatment of delirium in COVID-19 patients.

Review Meta Analysis Comparative Study
Comparison of the efficacy of updated drugs for the treatment on the improvement of cognitive function in patients with Alzheimer 's disease: A systematic review and network meta- analysis.
The recent emergence of updated drugs for the treatment of Alzheimer's disease (AD) has produced encouraging cognitive and clinical results in clinical trials, but there is still controversy over how to choose effective treatment options among these numerous drugs. The purpose of this network meta-analysis (NMA) is to compare and rank these drugs based on their efficacy. ⋯ Donanemab and Lecanemab showed good efficacy in ADCS-ADL and CDR-SB, respectively. GV-971 is the best choice to improve ADAS cogs and NPI.

Perinatal anoxia associated with sensorimotor restriction causes muscle atrophy and microglial activation: Meta-analysis of preclinical studies with implications for cerebral palsy.
Several experimental cerebral palsy models have been created to investigate cellular and molecular mechanisms involved in this condition and develop new therapeutic strategies. The model that has come closest to a motor phenotype similar to cerebral palsy is the one that combines perinatal anoxia with hindlimb sensorimotor restriction, as it induces visible changes at the peripheral and central levels. This systematic review with meta-analysis presents the impact of the cerebral palsy model that associates perinatal anoxia with hindlimb sensorimotor restriction on the nervous, muscular and skeletal systems. ⋯ The results of the meta-analysis reported a significant reduction in the media area of the soleus muscle fibers, increased number of glia cells and glia/neuron index in the somatosensory cortex, increased microglial activation in the hippocampus, and no changes in the corpus callosum thickness or neuron cells. The combination of perinatal anoxia and sensorimotor restriction entails muscle deficits and excessive activation of glial cells in brain areas. These results contribute to a methodological refinement of cerebral palsy models and favor new studies proposed for methodological elucidation in animal experimentation.
