The Role of Music Therapy in Supporting Intellectually Disabled Youth in Senegal

Introduction: Music therapy is a practice for helping and supporting people with intellectual and relational difficulties. This study illustrated the benefits of music therapy for young people living with intellectual disabilities (YLID) in an African context. Methodology: This study investigated six young individuals with intellectual disabilities who had undergone three years of music therapy. They were participants in the inclusive non-academic training program at the National School of Arts in Dakar from 2017 to 2019. Data collection utilized individual interviews with the youths, evaluation grids from teachers and psychiatrists. Guardians provided informed consent along with the assent of the young participants. Results: The six young were aged between 18 and 30 years old, with an average age of 24.6 years. Four of the YLID were male. Three young people with intellectual disabilities had delayed psychomotor development. Observations revealed the beneficial influence of music therapy on the health and well-being of young individuals. Music played a role in alleviating stress and anxiety among youth with intellectual disabilities (YLID), enhancing their mood and mental health. It assisted in navigating challenging situations and heightened alertness among YLID. Additionally, music therapy contributed to improvements in dyslexia, fine and gross motor skills, and memory development among intellectually disabled youth, ultimately facilitating their integration into society. Conclusion: In light of our results, music therapy makes a major contribution to the empowerment of YLID. Engaging in musical activities helps young people connect with others through instrumental expression and a sense of accomplishment. By facilitating music therapy, it becomes possible to combat discrimination and stigmatization, thus promoting the social inclusion of intellectually disabled youth. Therefore, it is important to promote music therapy in Senegal to meet the needs of YLID.

Associated Factors of Dental Caries among Intellectually Disabled Persons in Specialized Centers of Ouagadougou

Introduction: Several studies have reported a high prevalence of dental caries among the people with intellectual disabilities. In order to identify the sociodemographic, clinical and behavioral factors associated with it, we conducted a study in specialized centers welcoming subjects with intellectual disabilities in Ouagadougou (Burkina Faso). Objectives: The objective of this study was to identify the factors associated with it among intellectually disabled in the specialized centers of Ouagadougou. Methods: The study was cross-sectional analytical. The survey took place between November 2020 and January 2021 among people with intellectual disabilities in reception centers receiving a grant from the Ministry of Women, National Solidarity, Family and Humanitarian Action. Data collection was done with a questionnaire adapted from the World Health Organization (WHO) and dental caries was recorded according to WHO criteria in decayed, missing or filled teeth generating a DMF index. Logistic regression was used to identify factors associated with the presence of dental caries. Results: A total of 193 participants were included in the study with an average age of 12.4 years ± 7.9. The overall prevalence of caries measured with the DMF index was 58.6% 95% CI [51.2 - 65.8]. It was significantly associated with female gender (OR = 4.2;95% CI [1.4 - 12.5], p = 0,01), the clinical form of mental illness (epilepsy OR = 3.8 95%;CI [1.2 - 12.7], p = 0,02, trisomy OR = 5.0;95% CI [1.1 - 22.9], p = 0,03, motor autonomy OR = 0.2 95%;CI [0.1 - 0.7], p = 0,01) and at use of toothpaste OR = 9.33;95% CI [1.05 - 82.7], p = 0,04. Conclusion: Dental caries remains a very present pathology in most people living with an intellectual disability. Also, it is necessary to put in place prevention strategies to reduce its prevalence and improve access to oral care for these people.

Oral candidiasis and potential risk factors among disabled and nondisabled in Al-Baha region, Saudi Arabia

BACKGROUND Oral candidiasis(OC)is an oral health disease that could influence patients’oral health quality of life.AIM To estimate prevalence of OC among disabled and non-disabled individuals and its potential risk factors in the Al-Baha region,Saudi Arabia.METHODS An observational cross-sectional study was carried out among 148 disabled and non-disabled participants.The technique of concentrated oral rinse employing the Sabouraud Dextrose Agar medium accompanied with 0.05%chloramphenicol was conducted to assess and isolate candida.Oral examination using the World Health Organization guidelines was conducted to examine participants’oral hea-lth status.A pre-designed questionnaire was also used to evaluate sociodemo-graphic,medical history,and oral hygiene habits of the studied population.RESULTS Out of 148 participants(n=57,38%)had colonized candida.None of the studied population had visible Candida lesions.However,Candida was found in the oral rinses without the subject presenting any lesions or issues caused by Candida(asymptomatic colonization).The most common prevalent OC among participants were Candida albicans,Candida glabrata,Candida dubliniensis,Candida krusei,Candida tropicalis,and Candida parapsilosis(n=35,61%;n=8,14%;n=6,10%;n=5,9%;n=2,4%;and n=1,2%)respectively.Diabetes,smoking,poor plaque,and gingival status were key potential risk factors that significantly associated with candida’s density and presence(P=0.001,P=0.001,P=0.01,and P=0.01)respectively.Disability status had no statistically significant effect on presence and density of Candida.CONCLUSION The prevalence of OC is almost third of the studied population;thus,may provoke a need to develop preventive strategies to reduce the OC rate and establish solid treatment plans.

CNKSR2 interactome analysis indicates its association with the centrosome/microtubule system

The protein connector enhancer of kinase suppressor of Ras 2(CNKSR2),present in both the postsynaptic density and cytoplasm of neurons,is a scaffolding protein with several protein-binding domains.Variants of the CNKSR2 gene have been implicated in neurodevelopmental disorders,particularly intellectual disability,although the precise mechanism involved has not yet been fully understood.Research has demonstrated that CNKSR2 plays a role in facilitating the localization of postsynaptic density protein complexes to the membrane,thereby influencing synaptic signaling and the morphogenesis of dendritic spines.However,the function of CNKSR2 in the cytoplasm remains to be elucidated.In this study,we used immunoprecipitation and high-resolution liquid chromatography-mass spectrometry to identify the interactors of CNKSR2.Through a combination of bioinformatic analysis and cytological experiments,we found that the CNKSR2 interactors were significantly enriched in the proteome of the centrosome.We also showed that CNKSR2 interacted with the microtubule protein DYNC1H1 and with the centrosome marker CEP290.Subsequent colocalization analysis confirmed the centrosomal localization of CNKSR2.When we downregulated CNKSR2 expression in mouse neuroblastoma cells(Neuro 2A),we observed significant changes in the expression of numerous centrosomal genes.This manipulation also affected centrosome-related functions,including cell size and shape,cell proliferation,and motility.Furthermore,we found that CNKSR2 interactors were highly enriched in de novo variants associated with intellectual disability and autism spectrum disorder.Our findings establish a connection between CNKSR2 and the centrosome,and offer new insights into the underlying mechanisms of neurodevelopmental disorders.

Peripheral blood RNA biomarkers can predict lesion severity in degenerative cervical myelopathy

Degenerative cervical myelopathy is a common cause of spinal cord injury,with longer symptom duration and higher myelopathy severity indicating a worse prognosis.While numerous studies have investigated serological biomarkers for acute spinal cord injury,few studies have explored such biomarkers for diagnosing degenerative cervical myelopathy.This study involved 30 patients with degenerative cervical myelopathy(51.3±7.3 years old,12 women and 18 men),seven healthy controls(25.7±1.7 years old,one woman and six men),and nine patients with cervical spondylotic radiculopathy(51.9±8.6 years old,three women and six men).Analysis of blood samples from the three groups showed clear differences in transcriptomic characteristics.Enrichment analysis identified 128 differentially expressed genes that were enriched in patients with neurological disabilities.Using least absolute shrinkage and selection operator analysis,we constructed a five-gene model(TBCD,TPM2,PNKD,EIF4G2,and AP5Z1)to diagnose degenerative cervical myelopathy with an accuracy of 93.5%.One-gene models(TCAP and SDHA)identified mild and severe degenerative cervical myelopathy with accuracies of 83.3%and 76.7%,respectively.Signatures of two immune cell types(memory B cells and memory-activated CD4^(+)T cells)predicted levels of lesions in degenerative cervical myelopathy with 80%accuracy.Our results suggest that peripheral blood RNA biomarkers could be used to predict lesion severity in degenerative cervical myelopathy.

Forging an easier path through graduation:Improving the patient transition from paediatric to adult critical care

Adolescence and the journey to adulthood involves exciting opportunities as well as psychosocial stress for young people growing up.These normal experiences are potentially magnified for teenagers living with chronic illness or disability and their families.Advances in care have improved survival for children with a variety of serious chronic medical conditions such that many who may once have died in childhood now survive well into adulthood with ongoing morbidity.For those with highly complex needs,care is often provided at major paediatric hospitals with expertise,specially trained personnel,and resources to support young people and their families for the first decades of life.At the end of adolescence,however,it is generally appropriate and necessary for young adults and their caregivers to transition to the care of clinicians trained in the care of adults at general hospitals.While there are some well-managed models to support this journey of transition,these are often specific to certain conditions and usually do not involve intensive care.Many patients may encounter considerable challenges during this period.Difficulties may include the loss of established therapeutic relationships,a perception of austerity and reduced amenity in facilities oriented to caring for adult patients,and care by clinicians with less experience with more common paediatric conditions.In addition,there is a risk of potential conflict between clinicians and families regarding goals of care in the event of a critical illness when it occurs in a young adult with major disability and long-term health issues.These challenges present genuine opportunities to better understand the transition from paediatric to adult-based care and to improve processes that assist clinicians who support patients and families as they shift between healthcare settings.

Reevaluating health metrics:Unraveling the limitations of disabilityadjusted life years as an indicator in disease burden assessment

In 1993,the World Bank released a global report on the efficacy of health promotion,introducing the disability-adjusted life years(DALY)as a novel indicator.The DALY,a composite metric incorporating temporal and qualitative data,is grounded in preferences regarding disability status.This review delineates the algorithm used to calculate the value of the proposed DALY synthetic indicator and elucidates key methodological challenges associated with its application.In contrast to the quality-adjusted life years approach,derived from multi-attribute utility theory,the DALY stands as an independent synthetic indicator that adopts the assumptions of the Time Trade Off utility technique to define Disability Weights.Claiming to rely on no mathematical or economic theory,DALY users appear to have exempted themselves from verifying whether this indicator meets the classical properties required of all indicators,notably content validity,reliability,specificity,and sensitivity.The DALY concept emerged primarily to facilitate comparisons of the health impacts of various diseases globally within the framework of the Global Burden of Disease initiative,leading to numerous publications in international literature.Despite widespread adoption,the DALY synthetic indicator has prompted significant methodological concerns since its inception,manifesting in inconsistent and non-reproducible results.Given the substantial diffusion of the DALY indicator and its critical role in health impact assessments,a reassessment is warranted.This reconsideration is imperative for enhancing the robustness and reliability of public health decisionmaking processes.

老年人群慢性病共病模式与失能状况的关联研究:基于四川省抽样调查

背景随着人口老龄化的进展,慢性病共病和失能老年人的数量与日俱增,给社会带来沉重的医疗负担。共病和失能联系紧密,但目前关于共病模式和失能状况的相关性研究较少。目的本研究旨在以四川省为例识别我国老年人群中常见的慢性病共病模式,并从个体层面探讨不同共病模式与失能状况之间的相关性。方法于2022年8—11月采用定额随机抽样方法在四川省抽取501例60岁及以上的老年人群样本,收集其慢性病患病状况、失能状况及一般人口学等信息。通过自组织映射神经网络和K-Means相结合的二次聚类方法,识别老年人群的常见共病模式。基于2021年国家医疗保障局首个《长期护理失能等级评估标准(试行)》判定样本的失能等级,应用逻辑回归模型探究慢性病共病模式与失能等级之间的关系。结果501例样本中,共病患病率为62.3%(312/501),失能率为74.3%(372/501);最终确定6种共病模式:关节炎或风湿病-高血压模式;血脂异常-高血压模式;肾脏疾病-关节炎或风湿病模式;癌症-关节炎或风湿病模式;哮喘-高血压-消化系统疾病模式;情感精神-记忆相关疾病模式。二分类逻辑回归分析结果显示,共病人群的失能风险是无共病人群的6.3倍(OR=6.3,95%CI=3.9~10.3,P<0.05)。多因素多分类逻辑回归分析结果显示,6种共病模式的失能风险均增加(P<0.05);其中情感精神-记忆相关疾病模式的共病人群失能风险最大,是无共病人群的10.7倍(OR=10.7,95%CI=1.7~63.6),其次是癌症-关节炎或风湿病模式(OR=7.8,95%CI=2.4~24.8)。结论四川省老年人共病患病率较高,多种共病模式均与失能的发生显著相关,尤其是情感精神-记忆相关疾病模式和癌症-关节炎或风湿病模式。医疗卫生保健系统应重点关注患有共病的老年群体,基于不同共病模式制定精准有效的长期护理政策和策略,预防延缓失能的发生、发展,提高老年人健康福祉,节约社会医疗卫生资源。

Oswestry功能障碍指数评分中久坐和体力活动水平与椎间盘退变的因果关系

背景:观察性研究表明,椎间盘退变会影响久坐和体力活动水平,然而Oswestry功能障碍指数评分中久坐和体力活动水平与椎间盘退变之间的因果关系尚不明确。目的:通过孟德尔随机化方法探讨Oswestry功能障碍指数评分中久坐和体力活动水平与椎间盘退变的因果关系。方法:从大规模人群全基因组关联分析中选择5个与Oswestry功能障碍指数评分中行为学相关的特征:看电视的时间、用电脑的时间、轻度/中度/剧烈体力活动,分别提取这些行为学相关特征的工具变量。结合Finn Gen最新第9版数据库中提取椎间盘退变作为结局,进行孟德尔随机化分析。使用逆方差加权法、MR-Egger回归、简单中位数法、加权中位数法、加权中值法等回归模型OR值和95%CI评估Oswestry功能障碍指数评分中久坐和体力活动水平与椎间盘退变的因果关系。使用Cochran’s Q检验异质性、MR-Egger截距检验多效性、“留一法”检验单核苷酸多态性观察暴露因素和椎间盘退变因果关系的敏感性。结果与结论:孟德尔随机化逆方差加权法结果显示,看电视/用电脑的时间与椎间盘退变发病风险呈正向因果关联(OR=1.775,95%CI:1.418-2.221,P<0.001)/(OR=1.384,95%CI:1.041-1.839,P<0.001),轻度体力活动与椎间盘退变发病风险呈反向因果关联(OR=1.000,95%CI:0.999-1.000,P=0.020);MR-Egger截距分析轻度体力活动与椎间盘退变存在潜在的水平多效性(P=0.005),看电视的时间、用电脑的时间与椎间盘退变不存在水平多效性(P=0.521,P=0.851)。Cochran’s Q异质性分析看电视的时间、用电脑的时间与椎间盘退变存在异质性(P=3.33×10^(-11),P=0.001),轻度体力活动与椎间盘退变没有观察到显著的异质性(P=0.186)。以上结果表明:Oswestry功能障碍指数评分中久坐和体力活动水平与椎间盘退变存在双向因果关系,即不仅椎间盘退变会影响Oswestry功能障碍指数评分中久坐和体力活动水平,Oswestry功能障碍指数评分中久坐和体力活动水平也会影响椎间盘退变。补充了轻度体力活动对椎间盘退变积极影响的遗传证据,表明中度/剧烈体力活动与椎间盘退变没有显著的因果关系,并扩大了长时间看电视/用电脑的久坐行为是椎间盘退变危险因素的证据基础。

Clinical prognostic factors for disabling Crohn's disease: A systematic review and meta-analysis

AIM: To identify demographic and clinical factors asso-ciated with disabling Crohn's disease (CD). METHODS: A systematic review and meta-analysisof observational studies, focusing on the factors that can predict the prognosis of different outcomes of CD was undertaken. PubMed, ISI Web of Knowledge and Scopus were searched to identify studies investigat-ing the above mentioned factors in adult patients with CD. Studies were eligible for inclusion if they describe prognostic factors in CD, with inclusion and exclusion criteria defined as follows. Studies with adult patients and CD, written in English and studying association between clinical factors and at least one prognosis out-come were included. Meta-analysis of effects was un-dertaken for the disabling disease outcome, using odds ratio (OR) to assess the effect of the different factors in the outcome. The statistical method used was Mantel-Haenszel for fixed effects. The 16-item quality assess-ment tool (QATSDD) was used to assess the quality of the studies (range: 0-42). RESULTS: Of the 913 papers initially selected, sixty studies were reviewed and three were included in the systematic review and meta-analysis. The global QA-TSDD scores of papers were 18, 21 and 22. Of a total of 1961 patients enrolled, 1332 (78%) were classified with disabling disease five years after diagnosis. In two studies, age at diagnosis was a factor associated with disabling disease five years after diagnosis. Individu-als under 40 years old had a higher risk of developing disabling disease. In two studies, patients who were treated with corticosteroids on the first flare developed disabling disease five years after diagnosis. Further, perianal disease was found to be relevant in all of the studies at two and five years after diagnosis. Finally, one study showed localization as a factor associated with disabling disease five years after diagnosis, with L3 being a higher risk factor. This meta-analysis showed a significantly higher risk of developing disabling dis-ease at five years after initial diagnosis among patients younger than 40 years of age (OR=2.47, 95%CI: 1.74-3.51), with initial steroid treatment for first flare (OR=2.42, 95%CI: 1.87-3.11) and with perianal dis-ease (OR = 2.00, 95%CI: 1.41-2.85).CONCLUSION: Age at diagnosis, perianal disease, ini-tial use of steroids and localization seem to be indepen-dent prognostic factors of disabling disease.

The Need and Its Influence Factors for Community-based Rehabilitation Services for Disabled Persons in One District in Beijing

Purpose To explore the needs for basic community-based rehabilitation services for disabled persons in Xuanwu District, Beijing, China, and to identify factors which influence disabled persons to accept rehabilitation services. Method One hundred and eight disabled persons were selected by systematic sampling and simple random sampling to assess their needs for community-based rehabilitation services. Results Of the interviewees, 57A% needed the community-based rehabilitation services, but only 13.9% took advantage of it. The main factors influencing the interviewees to accept these services were cost （P〈0.05）, knowledge about rehabilitation medicine （P〈0.05）; and the belief in the therapeutic benefit of the community-based rehabilitation service （P〈0.05）. Conclusion A considerable gap exists between the supply of community-based rehabilitation services in Beijing and the needs for these services by disabled residents underscoring the need for improved availability, and for additional research.
