Meta-Analysis Review
The current evidence on the association of leukocyte telomere length (LTL) with age-related structural and cognitive changes in the brain is mixed. Herein conforming to PRISMA 2020 guidelines, we performed a systematic review and meta-analysis using data from 27 observational studies in non-demented individuals. We used effect size and p-value based meta-analysis methods considering marked heterogeneity among studies. We found that the longer LTL was associated with higher brain volume (β = 0.43, 95%CI: 0.36-0.50%, p = 0.008, N = 1102) and with higher global cognition (β = 0.01; 95%CI: 0.00-0.02, p = 0.03, N = 19609) by effect size based meta-analysis and with brain volume, hippocampal volume, global cognition, cognitive domains of attention/speed as well as executive functions by p-value based meta-analysis. No significant association of LTL with brain white matter hyperintensities was detected. Furthermore, the evidence strongly suggests a subgroup-specific canonical effect of telomeres, notably in older individuals and females. In conclusion, we provide meta-analytic evidence on the beneficial effect of telomeres on brain structure as well as cognition and advocate for a beneficial subgroup-specific effect that warrants further attention.

Review
Since the onset of COVID-19, studies suggest a significant increase in online gambling, potentially facilitated by increased time at home, social isolation and boredom. This study aimed to address what is known about the impact of the pandemic on gambling behaviour by conducting a mapping review. A systematic literature search was conducted using four online databases. Additional studies were identified using reference lists. Relevant studies were quality scored and their findings synthesised in terms of overall changes at the population level and potentially vulnerable groups. The weight of evidence from 35 relevant reports across 12 countries indicated reductions of gambling during the pandemic at the level of the general population. However, marked increases in gambling amongst vulnerable sub-populations including amongst young adults and people with pre-existing at-risk gambling were also noted. The impact of COVID-19 on gambling is highly contingent on context. If policy makers examine only population level data, this could overlook profound negative effects identified in those with at-risk gambling, gambling disorder, and amongst young adults.

Review
BACKGROUND
The advent of supraglottoplasty clearly has transformed the surgical management of severe laryngomalacia. The condition, however, generally runs a milder course, with spontaneous resolution the norm.
OBJECTIVES
To identify gaps in the knowledge and identify topics for future study.
METHOD
Systematic review of the literature.
RESULTS
The literature suggests that there is a range of abnormalities leading to the typical collapsing upper airway, and that neurological disease, other airway abnormalities, syndromes and gastroesophageal reflux all contribute to disease severity and influence outcomes. The procedures involved in supraglottoplasty are rarely specified, the indications for surgery are vaguely defined and the role of medical therapy is unclear.
CONCLUSION
Every review article or survey of opinion suggests that there is still a marked variation in individual practice and a lack of consensus.

Review
In recent times, novel oral anticoagulants (NOACs)/direct oral anticoagulants (DOACs) have emerged as an alternative to the traditionally used Vitamin K oral antagonists (VKA) like warfarin for the treatment of atrial fibrillation (AF). This systematic review and meta-analysis aims to evaluate the efficacy and safety of NOACs in patients with AF and, thus, the related thromboembolic risks and sequelae. Of the 131 published articles we examined, 11 were included in an in-depth systematic review. The articles we reviewed were from the past ten years, from 2013 onward. The analysis derived the efficacy and safety of NOACs in patients with AF and also included different patients' baseline characteristics and subgroups. This systematic review reiterates previous research findings of superior efficacy and safety of the use of NOACs in the AF population and also illuminates certain head-to-head comparisons of individual NOACs with warfarin. It digressed into subgroups of patients with different baseline characteristics to provide evidence and support the existing guidelines for the use of NOACs in the treatment of AF. Overall, there is marked efficacy and safety of NOACs in patients with AF, be they elderly or Asian, with decreased renal function, or with other comorbidities. Adherence to NOACs was also satisfactory. Despite such a review, there needs to be more research on vast subgroups and also on reversal antidotes like andexanet alfa and idarucizumab, as well as more head-to-head analysis between NOACs over a long duration of study, which would provide more answers and pinpoint reasons as to the differences that exist between demographics and subgroups in the usage of NOACs.

Meta-Analysis
INTRODUCTION
It is unclear whether hydrodilatation is beneficial in the management of frozen shoulder compared with other common conservative management modalities. This systematic review evaluates the efficacy of hydrodilatation for the management of frozen shoulder.
SOURCES OF DATA
A systematic review was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. An extensive search of PubMed, Embase, Scopus, Cochrane Central, Web of Science and CINAHL databases using multiple keyword combinations of 'shoulder', 'rotator', 'adhesive capsulitis', 'hydrodilatat*', 'distension' since inception of the databases to June 2023 was implemented.
AREAS OF AGREEMENT
Hydrodilatation leads to at least transient more marked improvements in shoulder disability and passive external rotation compared with intra-articular corticosteroid injections.
AREAS OF CONTROVERSY
Hydrodilatation improves passive external rotation in the longer term. Moreover, hydrodilatation may be a preferable option over manipulation under anaesthesia, given its lower cost and better patient convenience.
GROWING POINTS
Intensive mobilization after hydrodilatation is a promising adjuvant treatment option for patients suffering from a frozen shoulder.
AREAS TIMELY FOR DEVELOPING RESEARCH
Although current evidence suggests that hydrodilatation provides a transient improvement in disability in patients with frozen shoulder, its clinical relevance remains unclear. Further research is necessary to establish its role in the management of the condition.

Review
The enamel renal syndrome (ERS) is a rare autosomal recessive disease that is associated with mutations in the gene. The syndrome is characterized by impaired amelogenesis of the hypoplastic type and nephrocalcinosis, presenting with presence of thin or absence of enamel, late dental eruption, intrapulpal calcifications, bilateral nephrocalcinosis, and normal plasma calcium level. The objective is to characterize ERS by systematically literature reviewing, highlighting the main findings of the syndrome to increase knowledge about this condition in the health professionals. The study is a systematic review of the scientific literature, whose research was developed in the PubMed database in March 2018. A total of 69 articles were found. Two authors analyzed their abstracts and selected, according to the language and main subject, 30 articles to write this study. A total of 69 patients were cited in the studies and their data were analysed. There was gender equivalence and the ages ranged from 1 to 64 years old. There is a clear hereditary relation of the syndrome, since there was consanguinity in 18 cases, indicating a percentage of 26.08% and family history in 30 cases (43.47%). Laboratory changes vary greatly from patient to patient and may even remain unchanged. The relationship between the syndrome and the mutation in the gene can be proven from the data, since all patients with ERS screened by the mutation were positive. With the advancement of the ERS studies, some associations with the syndrome are suspected, such as the presence of gingival fibromatosis, hearing loss, and hypertrichosis. Thus, it is noticed that the syndrome does not show a predilection for gender or age and there is a strong hereditary character, marked by the consanguinity and family history of the patients. The association with the gene is reinforced, since the mutation was identified in all patients analyzed.

Review
Amyotrophic lateral sclerosis (ALS) causes dysphagia and consequent poor nutrition. Sometimes enteral feeding is offered. Percutaneous endoscopic gastrostomy (PEG) is currently the technique of choice for enteral nutrition of these patients. This systematic review addresses the role of PEG and other enteral feeding techniques in maintaining ALS patients' survival and quality of life and in identifying prognostic factors for survival, in order to optimize their usefulness. We also evaluated the mortality of enteral feeding in the first 30 days after each procedure and its complications. Studies were retrieved from Pubmed, Google Scholar, and Cochrane databases, using the relevant keywords, and by hand search. The inclusion criteria were prospective and retrospective designs of studies of people with clinically diagnosed ALS in whom gastrostomy or nasogastric enteral feeding were used in management, published in English. Studies with sample sizes <40, or which focused on a specific gastrostomy technique utilizing less than 30 subjects were excluded in order to avoid small sample bias. We conclude that PEG is safe and probably prolongs survival in non-malnourished ALS patients. However, older age at onset, marked loss of weight or reduced body mass index from symptomatic onset, and marked respiratory dysfunction negatively influence the outcome after PEG insertion. The currently available evidence does not meaningfully address the impact of PEG on quality of life in ALS. The literature about other enteral feeding techniques is insufficient for reliable conclusions. The optimum time for PEG insertion and preferences for specific gastrostomy techniques also require more investigation.

Review
Soft tissue dysfunction can result from the degeneration of tissues as in the case of degenerative tendinopathy or from the build-up of problematic scar tissue, which can be the result of several aggravating factors, including overuse injuries, acute or chronic trauma, or as a result of surgery. This dysfunction often results in impaired movement, pain, and swelling of the affected area, which can lead to patient dissatisfaction and a lower quality of life. These soft tissue dysfunctions also have a marked economic impact. Although a number of traditional treatments attempt to address these issues, no optimal treatment choice has emerged. Traditional treatments are not always successful, can be invasive, and can consume many medical resources. A relatively new treatment approach, Astym therapy, is a potentially useful, non-invasive, more cost-effective option. This therapy was developed to address soft-tissue dysfunctions by stimulating the regeneration of soft tissues and the resorption of inappropriate scar tissue/fibrosis. It has been reported to help with the resorption and remodeling of abnormal tissue, thereby leading to improved motion, function and pain relief. The purpose of this analysis was to review the published literature related to Astym therapy on various musculoskeletal disorders. Specifically, we evaluated the effectiveness of this therapeutic method on disorders related to the: (I) knee; (II) upper extremity; (III) hamstring muscles; and (IV) ankle and Achilles tendon injuries.

Review
Prevalence studies have shown heterogeneous use of home mechanical ventilation in different conditions, with a marked increase in uptake especially in users of noninvasive ventilation. Although randomized controlled trials have examined noninvasive ventilation in acute exacerbations of chronic obstructive pulmonary disease, for weaning from invasive ventilation and for postextubation respiratory failure, the evidence base for long-term noninvasive ventilation and comparisons with invasive ventilation are less well developed. The combination of noninvasive ventilation and cough-assist devices has reduced the indications for tracheotomy ventilation in some situations (e.g., Duchenne muscular dystrophy, spinal muscular atrophy, myopathies, and amyotrophic lateral sclerosis) and has also prolonged survival. Several excellent overviews have been written on the history of home mechanical ventilation and its evolution from negative pressure to positive pressure techniques, including a systematic review of outcomes. This review, instead, will cover recent trials, trends in the field, outcomes, and safety. Because the greatest growth has been in home noninvasive ventilation, this will be the main focus of this article.

Review
In recent years, soft robotics has developed considerably, especially since the year 2018 when it became a hot field among current research topics. The attention that this field receives from researchers and the public is marked by the substantial increase in both the quantity and the quality of scientific publications. In this review, in order to create a relevant and comprehensive picture of this field both quantitatively and qualitatively, the paper approaches two directions. The first direction is centered on a bibliometric analysis focused on the period 2008-2022 with the exact expression that best characterizes this field, which is "Soft Robotics", and the data were taken from a series of multidisciplinary databases and a specialized journal. The second direction focuses on the analysis of bibliographic references that were rigorously selected following a clear methodology based on a series of inclusion and exclusion criteria. After the selection of bibliographic sources, 111 papers were part of the final analysis, which have been analyzed in detail considering three different perspectives: one related to the design principle (biologically inspired soft robotics), one related to functionality (closed/open-loop control), and one from a biomedical applications perspective.
