Cognitive effects of piracetam in adults with memory impairment: A systematic review and meta-analysis.

Introduction: Piracetam, a widely recognized nootropic drug, is hypothesized to enhance memory function through its influence on synaptic plasticity and neurotransmitter levels. However, despite its popularity, there remains a lack of conclusive evidence regarding its impact on memory. Therefore, the present study aims to explore the effects of piracetam on memory in individuals with impaired cognitive function, comparing it to a placebo control group.

Does nocturnal use of a complete denture interfere with the degree of obstructive sleep apnea? A systematic review and meta-analysis.

Background: The impact of a complete denture on obstructive sleep apnea is not well understood. Therefore, this study aimed to evaluate the relationship between nighttime use of complete dentures and obstructive sleep apnea and determine if wearing a complete denture during sleep changes the degree of obstructive sleep apnea.

Methods: This systematic review followed the notification items for Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) and was recorded in the International Prospective Registry of Systematic Reviews (PROSPERO) under number CRD42020183167.

The influence of crown-to-implant ratio in single crowns on clinical outcomes: A systematic review and meta-analysis.

Statement Of Problem: A consensus about the effect of crown-to-implant (C/I) ratio in single crowns regarding the implant survival rate and marginal bone loss (MBL) is lacking.

Purpose: The purpose of this systematic review and meta-analysis was to evaluate the influence of C/I ratio in implant-supported single crowns on clinical outcomes.

Material And Methods: The search was made in the PubMed/MEDLINE, Scopus, and the Cochrane Library databases following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses criteria and registered with the International Prospective Register of Systematic Reviews (PROSPERO: CRD42018095711).

Effect of exercise training on subjective parameters in patients with obstructive sleep apnea: a systematic review and meta-analysis.

Obstructive sleep apnea (OSA) has many effects on subjective parameters of the disease, such as reduction in quality of life (QoL), sleep quality (SQ), and increases in daytime sleepiness. Studies have reported the beneficial effect of exercise training on OSA severity; however, whether it improves subjective parameters remains unclear. The purpose of the present review was to investigate the effect of exercise training on QoL, daytime sleepiness, and SQ in adults with OSA by summarizing the results of clinical trials.

Match analysis and heart rate of top-level female beach volleyball players during international and national competitions.

Background: This case-study compared match activities and time spent in selected heart rate intensity zones in top-level female beach volleyball players during National and International competitions.

Methods: A Blocker (180.2 cm; 72.

Influence of Diabetes on the Survival Rate and Marginal Bone Loss of Dental Implants: An Overview of Systematic Reviews.

We aimed to conduct an analysis of the systematic reviews (SRs) in literature about the implant survival rate (ISR) and marginal bone loss (MBL) in diabetic and nondiabetic patients. This work was registered in The International Prospective Register of Systematic Reviews (CRD42018095314) and was developed following Preferred Reporting Items for Systematic Reviews and Meta-Analyses and the Cochrane Library Handbook.

Modified technique for preparation of venous circulation resin casts in the cirrhotic liver.

This study describes two major adaptations for the preparation of resin casts in human cirrhotic liver, harvested at the time of transplantation. The first is the way of fixing the catheter in the ostia of the hepatic and portal veins through a cerclage, so as to prevent displacement of the catheter and / or leakage of the resin during its injection. The second is the extension of corrosion time in the NaOH solution, averaging 6.
