Meta-Analysis
BACKGROUND
Increasing evidence suggests an association between schizophrenia and atherosclerosis. We conducted a systematic review and meta-analysis of cell adhesion molecules, critically involved in early atherosclerosis, in schizophrenia.
METHODS
We searched electronic databases from inception to 11 November 2023 for case-control studies assessing vascular cell, VCAM-1, intercellular, ICAM-1, platelet endothelial cell, PECAM-1, neural cell, NCAM, and Down syndrome cell, DSCAM, adhesion molecules, selectins (E-, L-, and P-selectin), integrins, and cadherins in patients with schizophrenia and healthy controls. Risk of bias and certainty of evidence were assessed using the JBI checklist and GRADE, respectively.
RESULTS
In 19 eligible studies, there were non-significant between-group differences in the concentrations of cell adhesion molecules, barring higher P-selectin in patients with schizophrenia (standard mean difference, SMD = 2.05, 95 % CI 0.72 to 3.38, p = 0.003; I = 97.2 %, p<0.001; very low certainty of evidence). Limited or no information was available regarding PECAM-1, DSCAM, ESAM, integrins, and cadherins. In meta-regression and subgroup analysis, there were significant associations between the SMD of ICAM-1 and matrix used (plasma or serum) and pharmacological treatment of schizophrenia, and between the SMD of VCAM-1 and pharmacological treatment, but not with other study and patient characteristics.
CONCLUSIONS
The results of our systematic review and meta-analysis do not support a significant role of immunoglobulin-like adhesion molecules, selectins, integrins, or cadherins in mediating the associations between schizophrenia, atherosclerosis, and cardiovascular disease. Further studies are warranted to investigate these associations in patients with different cardiovascular risk and the effects of antipsychotic treatments on cell adhesion molecules and surrogate markers of atherosclerosis (PROSPERO registration number: CRD42023463916).

Review
The purpose of this study is to conduct a systematic review and -analysis of exercise interventions designed to improve cardiovascular responses in individuals with DS. A search for relevant articles was conducted on seven electronic databases: PubMed, PEDro, Google Scholar, Scopus, WOS, MEDLINE, and SPORT Discus. An electronic search was conducted on October 15, 2022, without applying any year constraints. The studies were chosen based on a predetermined set of inclusion and exclusion criteria. The methodology of the study was evaluated using the PEDro scale, and data analyses were conducted using the CMA v3 random effects model. In total, 625 articles were reviewed, and data from 10 randomized controlled trials (RCTs) involving DS were used in this -analysis. The results showed that exercise programs were effective in increasing VO (ml. kg min) (ES: 0.69; 95 % confidence interval [CI], 0.27-1.12; : 0.001), time to exhaustion (ES: 0.83; CI, 0.31-1.35, : 0.001), and VE (ES: 0.76; CI, 0.32-1.20; P: 0.001). No changes were found for HR (ES: 0.3; CI, -0.02-0.63, : 0.07), VO (ml·min) (ES: 0.45; CI, -0.01-0.92; : 0.06), or RER (ES: 0.45; CI, -0.09-0.98, : 0.10). No adverse effects were reported in any of the studies. In this -analysis and comprehensive review, exercise interventions may improve cardiovascular responses in DS; however, the association wasn't consistent across trials. RCTs with precise intervention criteria, large sample sizes, and long-term follow-up are needed in the future to demonstrate the benefits of exercise on cardiovascular responses in people with DS.

Review
INTRODUCTION
Epilepsy is one of the most frequent neurological comorbidities in patients with Down Syndrome (DS). Young patients and adults are the most affected, the latter mostly showing a phenotype labeled as "Late-onset myoclonic epilepsy" (LOMEDS). Status epilepticus (SE) is a life-threatening complication in patients with epilepsy. In this study, we described a non-convulsive SE (NCSE) case in a patient diagnosed with LOMEDS. We also performed a systematic review of the literature on SE diagnosis and treatment in patients with Down Syndrome.
METHODS
Clinical and demographic characteristics of a DS patient diagnosed with NCSE were described. The systematic literature search dissected the diagnostic and therapeutic management of SE in patients with DS. The following databases were used: PubMed, EMBASE, and Google Scholar.
RESULTS
5 DS individuals (4 from the past literature + 1 novel case report) with SE have been identified. The median age at SE onset was 42 years (IQR: 21-60.5 years). The most common SE type was myoclonic SE (MSE), followed by NCSE. Two cases of acute symptomatic etiology were described, whereas a progressive symptomatic etiology was otherwise reported. Ictal EEG recording information was available in two patients who showed generalized spike waves and polyspike and wave discharges. In 3 cases, SE was treated with intravenous antiseizure medications that produced a complete resolution.
CONCLUSION
SE may represent a rare complication in patients with DS. Although no definitive conclusions may be achieved due to the lack of evidence, treatment with valproic acid seems effective, especially in MSE. NCSE management is more challenging. It requires low doses of anesthetics, which should be used cautiously due to the high rate of complications.

Review
The main objective of this systematic review was to synthesize the evidence on the occurrence and characteristics of stuttering in individuals with Down syndrome and thus contribute knowledge about stuttering in this population. Group studies reporting outcome measures of stuttering were included. Studies with participants who were preselected based on their fluency status were excluded. We searched the Eric, PsychInfo, Medline, Scopus, and Web of Science Core Collection databases on 3rd January 2022 and conducted supplementary searches of the reference lists of previous reviews and the studies included in the current review, as well as relevant speech and language journals. The included studies were coded in terms of information concerning sample characteristics, measurement approaches, and stuttering-related outcomes. The appraisal tool for cross-sectional studies (AXIS) was used to evaluate study quality. We identified 14 eligible studies, with a total of 1,833 participants (mean = 131.29, standard deviation = 227.85, median = 45.5) between 3 and 58 years of age. The estimated occurrence of stuttering ranged from 2.38 to 56%, which is substantially higher than the estimated prevalence (1%) of stuttering in the general population. The results also showed that stuttering severity most often was judged to be mild-to-moderate and that individuals with Down syndrome displayed secondary behaviors when these were measured. However, little attention has been paid to investigating the potential adverse effects of stuttering for individuals with Down syndrome. We judged the quality of the evidence to be moderate-to-low. The negative evaluation was mostly due to sampling limitations that decreased the representability and generalizability of the results. Based on the high occurrence of stuttering and the potential negative effects of this condition, individuals with Down syndrome who show signs of stuttering should be referred to a speech and language pathologist for an evaluation of their need for stuttering treatment.

Meta-Analysis
Therapeutic exercise exerts positive effects by mitigating or reducing the motor or cognitive changes that people with Down syndrome undergo throughout their life. There are no updated systematic reviews that integrate the evidence available in a way that facilitates decision-making for physical rehabilitation teams. This study therefore aimed to consolidate the information available and compare the effects of different types of physical exercise on the motor function of adults with DS. We conducted a systematic review and meta-analysis of randomized clinical trials and quasi-experimental studies. The literature search was performed between January 2023 and February 2023 using the PubMed, SCIELO, Epistemonikos, and Lilacs databases. Studies were selected according to pre-determined inclusion and exclusion criteria. The risk-of-bias assessment was performed using the risk-of-bias rating tool for randomized clinical trial (RoB) and the risk of bias of non-randomized comparative studies was assessed using the risk of bias in non-randomized studies of interventions (ROBINS-I) tool. Risk-of-bias assessment and meta-analyses were performed using the RevMan software package. Sixteen studies met the eligibility criteria for the qualitative synthesis and 4 were included in the meta-analyses. Combined exercise significantly increased muscle strength both in the upper limbs (SMD = 0.74 [95% CI 0.25-1.22]) and lower limbs (SMD = 0.56[95% CI 0.08-1.04]). Aerobic exercise improved spatiotemporal gait parameters. Aerobic exercise showed significant improvements in dynamic balance while combined exercise significantly increased dynamic and static balance. The certainty of the evidence was low to moderate for all outcomes. There was low and moderate certainty of evidence for the outcomes proposed in this review. However, therapeutic exercise could be effective in improving muscle strength and gait functionality.

INTRODUCTION
The Hypoglossal Nerve Stimulator (HNS) is a novel therapy that has been extensively studied in adults and more recently, it has been incorporated in children with Down Syndrome (DS) with persistent obstructive sleep apnea after adenotonsillectomy and trial of continuous positive airway pressure treatment. This systematic review article aims to examine the existing literature on HNS use in children to explore the benefits, efficacy, and parental experiences.
METHODS
MEDLINE, Web of Science and EMBASE were searched to include all studies published up to March 2nd, 2023, on the topic of HNS use in pediatric population under 21 years old.
RESULTS
A total of 179 studies were initially identified from which 10 articles were consistent with the inclusion criteria. Nine articles addressed outcomes after implantation of the HNS device in children with DS and 1 article explored the parental experiences. Findings were similar across studies where after implantation of HNS, there was marked improvement in polysomnographic outcomes and quality of life scores with high level of compliance.
CONCLUSIONS
HNS holds promise as an effective treatment option for pediatric patients with DS and persistent OSA after AT and CPAP trials. It significantly improves sleep-disordered breathing, quality of life, and neurocognitive measures, leading to substantial and sustained benefits for these children. While the findings are encouraging, further research is needed to explore the potential of HNS in other pediatric populations without DS and to raise awareness among healthcare providers about this treatment option. Overall, HNS may offer significant long-term benefits for the overall well-being and health of pediatric patients with DS and persistent OSA.

Review
BACKGROUND
In recent years telehealth became a popular and a rational health service delivery approach, especially amidst multiple challenges posed while providing health care interventions during the COVID-19 pandemic.
AIM
We synthesized available evidence on telehealth for managing children with NDDs in the Asia-Pacific region with the aim of identifying successful methods.
METHODOLOGY
We systematically reviewed six electronic databases: MEDLINE, AMED, EMBASE, PsychInfo, Web of Science, and (CINAHL plus) using the keywords and database-specific subject headings from their inception to 25th August 2021. Review findings were synthesized narratively, and harvest plots were used to demonstrate the effect of interventions. The protocol and reporting the findings of this review adhered to PRISMA 2020 guidelines. PROSPERO registration: CRD 340690.
RESULTS
We harvested 30,823 records; 17,563 duplicates were removed, and 196 full-text articles were assessed for eligibility. 16 studies with multiple research designs were included in the review. Eight were from the Pacific region and eight represented Asia. The interventions targeted families and children with a variety of NDDs (autism spectrum disorder, Down syndrome, cleft lip and palate, hearing impairment, cerebral palsy etc.) via telehealth. Telehealth packages consisted of direct and indirect methods of synchronous, asynchronous, and hybrid approaches. All studies used parent-led intervention strategies. Telehealth reported a positive effect in 7/16 studies while five showed a neutral effect.
CONCLUSIONS
According to published evidence telehealth for children with NDDs is an evolving, evidence-based service facilitation modality in the Asia-Pacific region, with only a few published randomized controlled trials. The systematic review shows promising telehealth practices emerging across the region despite the diversity in NDDs studied.

OBJECTIVES
Isaac syndrome (IS) is a condition characterized by peripheral nerve hyperexcitability caused by voltage-gated potassium channel (VGKC)-complex antibodies. Muscle twitching, stiffness, hypertrophy, and dysautonomic characteristics, such as hyperhidrosis, are common manifestations. The syndrome can be autoimmune or paraneoplastic, with thymoma being a common cause of paraneoplastic IS. Furthermore, this condition could be handed down from one generation to another. However, there is limited information regarding outcomes, relapses, associated syndromes, associated malignancies (other than thymoma), and treatment options. Despite its rarity, there remains a need for effective management strategies for patients with IS. To address this gap, we conducted a systematic review to summarize the most common and effective treatments of IS in immunomodulatory agents and symptomatic medications, as well as to describe outcomes, relapses, and associated malignancies. Altogether, this review serves to guide clinical practice recommendations for IS and highlight areas for further research.
METHODS
We used the Preferred Reporting Items for Systematic Reviews and Meta-Analyses protocol to conduct a systematic review of cases reposted through the PubMed and Google Scholar databases. The terms "Isaac Syndrome" and "Acquired Neuromyotonia" were used. The Joanna Briggs Institute's critical appraisal tool was used to evaluate the quality of the included studies.
RESULTS
We identified 61 case reports and 4 case series, comprising a total of 70 patients with IS (mean age at onset: 42.5 ± 18 years, and 69% were males). Fourteen cases reported relapses. Thymoma was the most common malignancy associated with IS, followed by lymphoma. Among various serum antibodies, voltage-gated potassium channel-complex antibodies were the most reported antibodies elevated in IS (reported in 38 patients and elevated in 21 patients [55.2%]), followed by acetylcholine ganglionic receptor antibodies, which were reported in 30% of patients (n = 21) and were elevated in 5 cases. The most common electromyography findings were myokymic discharges (n = 22), followed by fasciculations (n = 21) and neuromyotonia (n = 19). For treatment, combining anticonvulsants such as carbamazepine with immunotherapy therapy showed the best results in controlling the symptoms. Among immunotherapy therapies, the combination of plasma exchange plus intravenous high-dose steroids achieved the best results in the acute treatment of IS ([n = 6], with improvement noted in 83.3% [n = 5] of cases). Among the symptomatic treatments with anticonvulsants, carbamazepine was the most efficacious anticonvulsant in treatment of IS, with an average effective dosing of 480 mg/day (carbamazepine was used in 32.3% of acute treatment strategies [n = 23], with improvement noted in 73.9% [n = 17] of cases).
CONCLUSIONS
IS a rare neuromuscular syndrome that tends to affect middle-aged men. These patients should be screened for thymoma and other malignancies such as lymphomas. The management of IS symptoms can be challenging, but based on our review, the combination of multiple immunosuppressives such as IV steroids and plasmapheresis with anticonvulsants such as carbamazepine seems to achieve the best results.

Meta-Analysis
BACKGROUND
Prone positioning has evolved as a therapeutic intervention for patients with acute respiratory distress syndrome (ARDS). ARDS remains a critical condition, with a mortality rate of approximately 40%. Prone positioning, which involves placing patients in a face-down position, has the potential to enhance gas exchange and improve lung mechanics, possibly leading to better patient outcomes.
OBJECTIVES
This comprehensive review aims to evaluate the impact of prone positioning on mortality (primary outcome) and the occurrence of adverse events (secondary outcome) in patients with ARDS compared to conventional supine positioning.
METHODS
We conducted an extensive systematic review, including studies published from 2000 to 2022. We searched databases including PUBMED, MEDLINE, EMBASE, CENTRAL, and WEB OF SCIENCE. Only randomized controlled trials (RCTs) that compared the outcomes of patients with ARDS in prone and supine positions were included. We employed the Cochrane risk of bias instrument to assess the methodological quality of the included RCTs.
RESULTS
Our review included a total of twelve RCTs involving 2736 patients, with 1401 patients in the prone position. The meta-analysis demonstrated a lower mortality rate among patients in the prone position compared to those in the supine position (odds ratio [OR], 0.71; 95% confidence interval [CI], 0.52-0.98; P = .04). Notably, there was a higher incidence of pressure sores in patients placed in the prone position (OR, 0.15; 95% CI, 0.09-0.20) compared to those in the supine position. However, there were no statistically significant differences in the occurrence of arrhythmias, unplanned extubation, or pneumothorax between the two positioning strategies.
CONCLUSIONS
Prone positioning offers potential benefits for patients with ARDS by reducing mortality rates. However, it is important to note that there is an associated risk of pressure sores. Further research and clinical consideration are needed to optimize the use of prone positioning in ARDS management.

Review
PURPOSE
The purpose of this scoping review was to (a) summarize methodological characteristics of studies examining vocal characteristics of infants at high risk for neurological speech motor involvement and (b) report the state of the high-quality evidence on vocal characteristic trends of infants diagnosed or at high risk for cerebral palsy (CP).
METHOD
The PRISMA (Preferred Reporting Items of Systematic Reviews and Meta-Analyses) extension for scoping reviews was followed for reporting our review. Studies measured prelinguistic vocal characteristics of infants under 24 months with birth risk or genetic conditions known to commonly present with speech motor involvement. Fifty-five studies met criteria for Part 1. Eleven studies met criteria for synthesis in Part 2.
RESULTS
A smaller percentage of studies examined infants with or at risk for CP compared to studies examining genetic conditions such as Down syndrome. The median year of publication was 1999, with a median sample size of nine participants. Most studies were conducted in laboratory settings and used human coding of vocalizations produced during caregiver-child interactions. Substantial methodological differences were noted across all studies. A small number of high-quality studies of infants with or at risk for CP revealed high rates of marginal babbling, low rates of canonical babbling, and limited consonant diversity under 24 months. Mixed findings were noted across studies of general birth risk factors.
CONCLUSIONS
There is limited evidence available to support the early detection of speech motor involvement. Large methodological differences currently impact the ability to synthesize findings across studies. There is a critical need to conduct longitudinal research with larger sample sizes and advanced, modern technologies to detect vocal precursors of speech impairment to support the accurate diagnosis and prognosis of speech development in infants with CP and other clinical populations.
