A systematic review, meta-analysis, and network analysis of diagnostic microRNAs in glaucoma.

Glaucoma is a chronic neurodegenerative process of the optic nerve that is the leading cause of blindness worldwide, and early diagnosis of the disease could greatly affect patients' prognoses. The pathophysiology of glaucoma is complicated by a combination of genetic and epigenetic factors. Deciphering the early diagnostic biomarkers in glaucoma could attenuate the disease's global burden and help us understand the exact mechanisms involved in glaucoma. The microRNAs are members of a larger family of non-coding RNAs that play an essential role in the epigenetic basis of glaucoma. A systematic study and meta-analysis of diagnostic microRNAs in glaucoma, jointly with network analysis of target genes, were carried out on published papers assessing differentially expressed microRNAs in human subjects. In total, 321 articles were found, and, after screening, six studies were eligible for further analysis. 52 differentially expressed microRNAs were found, of which 28 and 24 were up-regulated and down-regulated, respectively. Only 12 microRNAs were qualified for meta-analysis, with overall sensitivity and specificity of 80% and 74%, respectively. Then, using network analysis, it became apparent that the VEGF-A, AKT1, CXCL12, and HRAS genes were the most important targets for the microRNAs. Perturbations in WNT signaling, protein transport, and extracellular matrix organization pathways were discovered to be important in the etiology of glaucoma using the community detection approach. This study tries to uncover the promising microRNAs and their target genes that govern the epigenetics of glaucoma.

The characteristics of foreign bodies aspirated by children across different continents: A comparative review.

BACKGROUND: Foreign body aspiration (FBA) is a common issue in pediatric emergencies, with regional variations. Various cultures and foods, parents' and physicians' inadequate experience, and lack of bronchoscopy equipment are some attributable factors in the regional variation of FBA. AIM: To more accurately represent the demographic characteristics of aspirated foreign bodies (FBs) across various continents, this review attempted to provide organized information based on the reviewed articles. METHODOLOGY: A search was conducted in PubMed/PubMed Central, EMBASE, and google scholar. From the 36 included articles, information on age, gender, bronchoscopy type, type of FB, location, history of choking, and time elapsed between aspiration and admission were extracted. RESULTS: A total of 14,469 cases were evaluated. According to the findings, children under two accounted for more than 75% of FBAs. Nuts and seeds were the most common FBs in most countries, whereas plastic and metal objects had higher rates in Brazil, and calcified objects were more prevalent in Thailand. The right bronchus was the most frequent location, and rigid bronchoscopy was the most often utilized type of bronchoscope. In addition, a significant percentage of patients were referred to the emergency rooms in the first 12-24 h following the aspiration incident. Moreover, Asian patients reported more choking history, and Europeans had fewer witnesses of FBA. CONCLUSIONS: There is a lack of standardized reporting systems and organized guidelines in pediatric FBA. To select the ideal time for endoscopies and create educational programs, a collaboration between experienced researchers, pediatric pulmonologists, radiologists, and otolaryngologists is required.

The therapeutic role of lasers in primary localized cutaneous amyloidosis: a systematic review.

With the investigation of the efficacy of laser therapy in primary localized amyloidosis(PLCA) only recently starting to materialize, we aimed to review the currently available studies of laser therapy in the management of the disease. We searched PubMed, Scopus, Embase, Web of Science, Cochrane, and ProQuest online databases with a specified search strategy, assessed the quality of each study, and then extracted the eligible data. Five RCTs(randomized controlled trials), one non-randomized controlled trial, three case series, and nine case reports(18 in total) were included. Overall, carbon dioxide (CO2), neodymium-doped:yttrium aluminum garnet (Nd:YAG), pulsed dye (PDL), Er (Erbium):YAG, and yttrium/erbium fiber were the studied lasers. One hundred fifty-five cases in total underwent laser therapy, with CO2 being the most frequent laser. Almost all studies demonstrated significantly desirable outcomes, while only mild and transient side effects were noted. Even though the studies' results were significant, we noticed that implementing a consistent methodology and a standardized objective assessment method was missing. Therefore, we recommend that future studies be conducted with less heterogeneous data for a more definite conclusion.
