The most common form of SMA is linked to 5q (5q-SMA) and is classified into subtypes according to the age of onset and maximum motor function achieved. The severity ranges from progressive infantile paralysis and premature death (type 1) to limited motor neuron loss in adults (type 4). The LATAM RegistrAME protocol is an observational, retrospective, prospective international multicenter clinical registry study involving Latin Americans. We will include 5q-SMA patients across all age groups, from pediatric to adult, to describe their clinical characteristics and disease progression. The protocol will use an international clinical research form based on the Treat Neuromuscular Disease Global Academic Network (TREAT-NMD), which focuses on advancing research on neuromuscular disorders in patients with spinal muscular atrophy. The study will include six countries in Latin America, sampling a total of 415 patients with SMA and 5q-SMA types 1, 2, 3, and 4 of all ages and both sexes who have genetically confirmed 5q-SMA. The mean follow-up period was 24 months. The primary outcomes will be the description of general clinical characteristics, access to medications capable of modifying the course of the disease, functional assessments, motor milestones, and ventilatory support. This study will provide insights into 5q spinal muscular atrophy patients in Latin America to better understand their clinical characteristics, use of medications, and outcomes while supporting further clinical management protocols and clinical trials.

However, no systematic review has yet assessed its impact. Therefore, this study aimed to conduct a comprehensive review and meta-analysis on the comparative efficacy and safety of autologous platelet concentrates in treating macular hole. A systematic review of the literature on autologous platelet concentrate therapy for macular hole was conducted in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines on September 9, 2023. Databases, including PubMed, the Cochrane Library, Web of Science, and Embase, were queried. A meta-analysis of random effects was performed. Efficacy was evaluated through anatomical closure, reopening of the macular hole at 6 months, average improvement of 2 lines, and visual field loss. Safety was evaluated by monitoring complications. A systematic search of multiple databases identified six studies (three randomized controlled trials and three non-randomized cohort studies) involving 616 patients (626 eyes). Autologous platelets concentrate therapy significantly improved macular hole closure compared to that in the controls (OR=4.35; 95%CI=2.08-9.10; p<0.0001; I²=9%). No significant differences were observed in hole reopening at 6 months, post-operative visual acuity improvement by 2 lines or more, or visual field loss between autologous platelets concentrate and control groups. The overall complication rates were similar between groups. Thus, autologous platelet concentrate therapy shows promise for promoting macular hole closure, particularly in smaller holes. Further research with standardized protocols, prolonged follow-ups, and larger sample sizes is needed to fully understand its benefits and limitations in macular hole closure.
