Un análisis integrado entre la calidad de vida y las necesidades de apoyo de personas adultas con discapacidad intelectual en Chile / An integrated analysis between the quality of life and the support needs of adults with intellectual disabilities in Chile

El paradigma de apoyos y el de calidad de vida se han transformado en guías fundamentales para los avances en el ámbito de la discapacidad intelectual (DI). Con base en una muestra de 93 personas adultas con DI, se analiza, desde un enfoque cuantitativo no experimental, la relación entre la calidad de vida y las necesidades de apoyo, aplicando la escala INICO-FEAPS y la escala de Intensidad de Apoyos (SIS) para cada constructo. Los principales resultados evidencian que existe una relación fuerte e indirecta entre calidad de vida y necesidades de apoyos, y también la relevancia de analizar dichos resultados desde variables como grado de discapacidad, sexo o nivel socioeconómico. La discusión permite inferir la necesidad de discutir nuevas estrategias en torno a categorías como el grado de discapacidad, la autodeterminación e inclusión social, como elementos facilitadores de la calidad de vida y apoyos desde un enfoque integral que contribuya al desarrollo de estrategias de programas sociales para la población con DI.

The support paradigm and the quality of life paradigm have become fundamental guides for progress in the field of Intellectual Disability (ID). Based on a sample of 93 adults with ID, the relationship between Quality of Life and Support Needs is analyzed from a non-experimental quantitative approach, applying the INICO-FEAPS scale and the SIS Support Intensity scale for each construct. The main results show that there is a strong and indirect relationship between quality of life and support needs, and the relevance of analyzing these results from variables such as the degree of disability, sex or socioeconomic level. The discussion allows us to infer the need to discuss new strategies around categories such as the degree of disability, self-determination and social inclusion, as facilitating elements of quality of life and supporting a comprehensive approach that contributes to the development of social program strategies for the population with ID.

Mean cycloplegic refractive error in emmetropic adults – The Tehran Eye Study / Error refractivo ciclopléjico medio en adultos emétropes: estudio ocular de Teherán

Purpose: In children under 20 years, refractive development targets a cycloplegic refractive error of +0.5 to +1.5D, while presbyopes over 40 years generally have non-cycloplegic errors of ≥ +1D. Some papers suggest these periods are separated by a period of myopic refractive error (i.e., ≤ –0.50D), but this remains unclear. Hence, this work investigates the mean cycloplegic refractive error in adults aged between 20 – 40 years. Methods: In 2002 a cross-sectional study with stratified cluster sampling was performed on the population of Tehran, providing cycloplegic and non-cycloplegic refractive error data for the right eyes of 3,576 participants, aged 30.6 ± 18.6 years (range: 1–86 years). After grouping these data into age groups of 5 years, the refractive error histogram of each group was fitted to a Bigaussian function. The mean of the central, emmetropized peak was used to estimate the mean refractive error without the influence of myopia. Results: The mean cycloplegic refractive error at the emmetropized peak decreased from +1.10 ± 0.11D (95 % confidence interval) to +0.50 ± 0.04D before 20 years and remains stable at that value until the age of 50 years. The non-cycloplegic refractive error also sees a stable phase at 0.00 ± 0.04D between 15 – 45 years. After 45 – 50 years both cycloplegic and non-cycloplegic refractive error become more hypermetropic over time, +1.14 ± 0.12D at 75 years. Conclusions: The cycloplegic refractive error in adults is about +0.50D between 20 – 50 years, disproving the existence of the myopic period at those ages.(AU)

A within-subject examination of grandparents' physical activity and sedentary behavior levels in the presence or absence of grandchild care provision.

BACKGROUND: This study aimed to examine within-subject differences in levels of physical activity (PA) and sedentary behavior (SB) among Flemish grandparents aged 50 years and older during a day of providing versus not providing grandchild care. Additionally, grandparents' PA and SB levels of the specific caregiving moment within the included care day were also compared with those of the corresponding specific time frame on the matching non-care day. METHODS: Data were obtained and pooled from three assessment time points of the Healthy Grandparenting Project. Objectively measured PA and SB levels were assessed through ActiGraphs wGT3x(+) worn during waking hours for seven consecutive days and expressed relative to the total wear time of the selected days or moments (i.e., percentage of time per day or per moment). Generalized linear mixed models were used to evaluate the within-subject differences in grandparents' light intensity PA (LIPA), moderate-to-vigorous intensity PA (MVPA) and SB levels between a care and non-care day as well as between the care and non-care moment of those respective days. RESULTS: A total of 92 grandparents (64.6 ± 4.8 years, 67.4% women) were included in the analyses. During the care day and care moment, grandparents showed higher relative levels of LIPA (∆=4.0% and ∆=7.9%, respectively) and lower relative levels of SB (∆=3.7% and ∆=6.7%, respectively) as compared to their respective non-care day and non-care moment (all p < 0.001). While there was no significant difference in relative MVPA levels between a day of providing versus not providing grandchild care (∆=0.3%, p = 0.500), the grandparents showed significantly lower relative levels of MVPA during the specific care moment against the non-care moment (∆=1.3%, p = 0.029). CONCLUSIONS: The higher percentage of time of LIPA and lower percentage of time spent on SB during a care day and care moment compared to a non-care day and non-care moment, highlight the positive impact of grandchild care provision on grandparents' activity levels, potentially improving other health-related outcomes. Furthermore, grandparents seem to compensate for their lower MVPA levels during the actual care moment since no differences in MVPA levels were found at day level when compared to a day without grandchild care.

Antipsychotic Prescribing in Older Adults after In-Hospital Initiation.

Background: In older adults, the use of antipsychotics to treat delirium or the behavioural and psychological symptoms of dementia is potentially inappropriate and may be associated with adverse effects. Antipsychotics newly initiated in hospital may be inadvertently continued after discharge. In the Saskatchewan Health Authority (SHA) - Regina area, the frequency and duration of antipsychotic continuation for older adults after initiation during a hospital stay is unknown. Objectives: To describe potentially inappropriate antipsychotic use in older adults after discharge from hospital, specifically rates of postdischarge antipsychotic therapy after initiation in hospital and continuation up to 180 days after discharge; prescribing regimens used; risk factors associated with continuation; pharmacist involvement; and plans for antipsychotic discontinuation, tapering, and/or follow-up. Methods: This retrospective chart review included inpatients 65 years of age or older who were discharged from medicine units at SHA - Regina area hospitals between September 30, 2021, and June 28, 2022. Outpatient dispensing histories were also gathered. Results: Of the 189 patients included in the analysis, 60 (31.7%) had continuation of antipsychotic therapy at discharge. Of these, 48 (80.0%), 33 (55.0%), and 24 (40.0%) had continuation of antipsychotic therapy at 30, 90, and 180 days after discharge, respectively. Of the patients with continuing antipsychotic therapy, 53 (88.3%) were 75 years of age or older, and 9 (15.0%) had documentation of an outpatient antipsychotic follow-up plan. Conclusions: Postdischarge continuation of antipsychotics was similar to that reported in the literature. Patients continued on antipsychotics after discharge were at a greater than 50% risk of continuation at 90 days and were unlikely to have a follow-up plan. Future quality improvement efforts should include standardized prioritization of medication reviews, documentation of indications, and regular reassessment of therapy.

Contexte: Chez les personnes âgées, l'utilisation d'antipsychotiques pour traiter le délire ou les symptômes comportementaux et psychologiques de la démence est potentiellement inappropriée et associée à des effets indésirables. Le traitement antipsychotique initié à l'hôpital pourrait se poursuivre par inadvertance après le congé. Dans la région de Regina de la Saskatchewan Health Authority (SHA), la fréquence et la durée du maintien d'antipsychotiques chez les personnes âgées après l'initiation au cours d'un séjour à l'hôpital sont inconnues. Objectifs: Décrire l'utilisation potentiellement inappropriée d'antipsychotiques chez les personnes âgées après le congé de l'hôpital, en particulier les taux de traitement antipsychotique initié à l'hôpital qui continue après le congé et son maintien jusqu'à 180 jours après le congé; les schémas de prescription utilisés; les facteurs de risque associés au maintien; l'implication du pharmacien; et les plans visant à arrêter, réduire progressivement et/ou à faire le suivi de la prise d'antipsychotiques. Méthodologie: Cet examen rétrospectif des dossiers comprenait des patients hospitalisés âgés d'au moins 65 ans qui étaient sortis des unités de médecine d'hôpitaux de la région de Regina de la SHA entre le 30 septembre 2021 et le 28 juin 2022. Les historiques de délivrance en ambulatoire ont également été recueillis. Résultats: Sur les 189 patients inclus dans l'analyse, 60 (31,7 %) ont continué leur traitement antipsychotique au moment du congé. Parmi eux, 48 (80,0 %), 33 (55,0 %) et 24 (40,0 %) continuaient leur traitement antipsychotique à 30, 90 et 180 jours après leur congé, respectivement. Parmi les patients recevant un traitement antipsychotique continu, 53 (88,3 %) étaient âgés d'au moins 75 ans et 9 (15,0 %) avaient un plan de suivi antipsychotique ambulatoire. Conclusions: Le maintien des antipsychotiques après le congé était similaire à celui rapporté dans la littérature. Les patients qui continuaient à prendre des antipsychotiques après leur congé couraient un risque supérieur à 50 % de continuer à 90 jours et étaient peu susceptibles de disposer d'un plan de suivi. Les futurs efforts d'amélioration de la qualité devraient comprendre une priorisation standardisée des examens des médicaments, la documentation des indications et une réévaluation régulière du traitement.

Prevalence, Habit Pattern, and Awareness on Harmful Effects of Tobacco/Areca Nut Use among Patients Visiting a Tertiary Care Center in Sri Lanka.

S.P. Kalpana Jeewanthi SubasingheBackground The carcinogenicity of tobacco and areca nut is well established worldwide. Areca nut is the fourth most common psychoactive substance identified recently. The effects of areca nut on the autonomic nervous system make the users dependent on the habit which has been an emerging health issue among Sri Lankan adults and adolescents. This study aimed to evaluate the prevalence and patterns of these risk habits among the patients attending a tertiary care center in Sri Lanka, and their awareness of the harmful effects of the habit. Method A hospital-based cross-sectional study was conducted among 512 patients using an interviewer-administered questionnaire. Results The sample consisted of 167 (33%) tobacco consumers. The average age of the initiation of tobacco consumption was 23.66 years (standard deviation ± 8.04). Age ( p = 0.001), gender ( p = 0.001), income ( p = 0.005), and educational level ( p = 0.001) are significantly associated with tobacco consumption. There is a strong likelihood for tobacco consumers to consume areca nut (odds ratio [OR] 30.58, 95% confidence interval [CI] 17.05-54.88) and alcohol (OR 11.16, 95% CI 6.91-17.98) at any stage in their lives. The majority of the tobacco consumers (61%) were smokeless tobacco users. Areca nut consumers are 0.44 times more likely to know its carcinogenic effects than nonconsumers (95% CI 0.28-0.69). Tobacco consumers are more likely to be aware of the harmful effects of tobacco consumption than nonconsumers (OR 1.11, 95% CI 0.45-2.74). Sixty percent have made at least one attempt to quit the habit. Sixty-two percent of the unsuccessful quitters reported the reason as "addiction." Conclusion Prevalence of smokeless tobacco consumption prevails at a high level among Sri Lankans. Tobacco and areca nut users are more likely to be aware of its harmful effects than the nonconsumers but unable to quit the habit due to the psychoactive properties of tobacco and areca nut.

Association between the triglyceride glucose index, triglyceride-glucose body mass index and diabetic kidney disease in adults with newly diagnosed type 2 diabetes.

Background: The triglyceride glucose (TyG) index has been proved to be a reliable marker of diabetic kidney disease (DKD). Objective: We further investigated the association between TyG index, and its derivative, triglyceride-glucose body mass index (TyG-BMI), and the risk of DKD among adults with newly diagnosed type 2 diabetes (T2D). Methods: This cross-sectional study was conducted among patients with newly diagnosed T2D. We assessed the correlation between TyG index, TyG-BMI, and the risk of DKD using logistic regression analysis, restricted cubic spline analysis, trend tests, receiver operating characteristic curve, and subgroup analyses. Results: Among the 924 included patients, 199 (21.5%) had DKD. Logistic regression revealed that TyG index (odds ratio [OR] 1.232, 95% confidence interval [CI] 1.064-1.428, p = 0.005) and TyG-BMI (OR 1.003, 95% CI 1.000-1.006, p = 0.021) were risk factors for DKD. The trend test demonstrated a dose-response association between TyG index (p for trend = 0.004), TyG-BMI (p for trend = 0.035), and the risk of DKD. Restricted cubic spline analysis indicated a nonlinear correlation between TyG index and the risk of DKD, with an increase in the risk of DKD when the TyG index was greater than 9.68 (p for nonlinearity = 0.014). In contrast, TyG-BMI and the risk of DKD exhibited a linear dose-response relationship, with an increase in the risk of DKD when the TyG-BMI was greater than 243 (p for nonlinearity = 0.034). According to the receiver operating characteristic curve, the optimal cutoff values for TyG index and TyG-BMI were 10.08 and 221.5, respectively. Conclusion: Among newly diagnosed T2D patients, the risk of DKD increases with the increase of TyG index and TyG-BMI, with their respective cut-off values being 9.68 and 243. Both TyG index and TyG-BMI have poor diagnostic value for the risk of DKD.

Promising directions for human-robot interactions defined by older adults.

Introduction: Older adults are engaging more and more with voice-based agent and social robot technologies, and roboticists are increasingly designing interactions for these systems with older adults in mind. Older adults are often not included in these design processes, yet there are many opportunities for older adults to collaborate with design teams to design future robot interactions and help guide directions for robot development. Methods: Through a year-long co-design project, we collaborated with 28 older adults to understand the key focus areas that older adults see promise in for older adult-robot interaction in their everyday lives and how they would like these interactions to be designed. This paper describes and explores the robot-interaction guidelines and future directions identified by older adults, specifically investigating the change and trajectory of these guidelines through the course of the co-design process from the initial interview to the design guideline generation session to the final interview. Results were analyzed through an adapted ethnographic decision tree modeling approach to understand older adults' decision making surrounding the various focus areas and guidelines for social robots. Results: Overall, over the course of the co-design process between the beginning and end, older adults developed a better understanding of the robot that translated to them being more certain of their attitudes of how they would like a robot to engage with them in their lives. Older adults were more accepting of transactional functions such as reminders and scheduling and less open to functions that would involve sharing sensitive information and tracking and/or monitoring of them, expressing concerns around surveillance. There was some promise in robot interactions for connecting with others, body signal monitoring, and emotional wellness, though older adults brought up concerns around autonomy, privacy, and naturalness of the interaction with a robot that need to be further explored. Discussion: This work provides guidance for future interaction development for robots that are being designed to interact with older adults and highlights areas that need to be further investigated with older adults to understand how best to design for user concerns.

Tablet allergen immunotherapy: the anaphylaxis issue.

For the first time 15 years ago, tablet allergen immunotherapy (T-AIT) formulations were approved by regulatory agencies for treating allergic rhinitis caused by grass pollen in adults and children aged >5 years. Extensive evidences existed about effectiveness and safety of AIT. However, the safety profile is particularly compelling in children. Generally, T-AIT causes local reactions, mostly in the oral cavity, that are usually mild-to-moderate and often self-resolving. However, systemic allergic reactions are also observed with T-AIT, anaphylaxis representing the most fearsome adverse event, considering that it occurs in subjects treated for allergic rhinitis. Therefore, we conducted a literature search of patients reporting anaphylaxis because of T-AIT. Nine cases of anaphylactic reactions were reported in literature. Notably, no death was reported using T-AIT. This outcome was very important as it underscored the substantial safety of T-AIT. However, T-AIT deserves careful attention, mainly in the pediatric population. In this regard, after the first report of anaphylactic reaction at the first administration of T-AIT, manufacturers recommended that the first dose should be administered in a medical facility in the presence of staff with experience in managing anaphylaxis and the patient should be observed for at least 30 min. Interestingly, reported anaphylactic reactions were due to grass pollen extracts, with no report concerning other allergen extracts. However, it is relevant to note that anaphylactic reactions because of T-AIT are not reported in recent years.

Causes, risks and care circumstances associated with death in older adults diagnosed with HIV in a tertiary centre in Malaysia.

BACKGROUND: A substantial number of older adults succumb soon after HIV diagnosis despite ART. We explored the causes, risk factors and circumstances before death among older adults acquring HIV. METHODS: We recruited individuals newly diagnosed at our centre from 2016-2020 and analysed data of those who died. Patients were stratified to older (≥50 years) or younger (<50 years) based on their age at diagnosis and attributes were compared. The Cox proportional multivariable model was used to identify factors associated with all-cause mortality. RESULTS: Among 75 deaths reported, the majority of deaths were AIDS-related and late presentation was common in both age groups. The majority of deaths occurred in the first 12 months after care presentation and over two-thirds in both groups disengaged from care prior to death. Older age remained an independent factor associated with death after adjusting for confounders including opportunistic infections, late presentation to care, ART initiation and chronic comorbidities at presentation. CONCLUSION: Most causes of death in our setting were AIDS-related and associated with late care presentation both in young and older individuals, although older age at diagnosis remained an independent risk factor. Our findings highlight the urgent need to encourage prompt ART initiation following diagnosis, especially in older adults.

Pharmacotherapy for Coronary Artery Disease and Acute Coronary Syndrome in the Aging Population.

PURPOSE OF REVIEW: To provide a comprehensive summary of relevant studies and evidence concerning the utilization of different pharmacotherapeutic and revascularization strategies in managing coronary artery disease and acute coronary syndrome specifically in the older adult population. RECENT FINDINGS: Approximately 30% to 40% of hospitalized patients with acute coronary syndrome are older adults, among whom the majority of cardiovascular-related deaths occur. When compared to younger patients, these individuals generally experience inferior clinical outcomes. Most clinical trials assessing the efficacy and safety of various therapeutics have primarily enrolled patients under the age of 75, in addition to excluding those with geriatric complexities. In this review, we emphasize the need for a personalized and comprehensive approach to pharmacotherapy for coronary heart disease and acute coronary syndrome in older adults, considering concomitant geriatric syndromes and age-related factors to optimize treatment outcomes while minimizing potential risks and complications. In the realm of clinical practice, cardiovascular and geriatric risks are closely intertwined, with both being significant factors in determining treatments aimed at reducing negative outcomes and attaining health conditions most valued by older adults.

Perspectives of adolescents and young adults on cannabis use during pregnancy.

PURPOSE: Rates of cannabis use during pregnancy are highest for adolescents and young adults (AYAs). This study aims to understand AYA perspectives regarding the medical and legal consequences of prenatal and parental cannabis use. METHODS: This study delivered five open-ended survey questions regarding prenatal cannabis use in May/June 2022 via a text message polling platform to the MyVoice cohort, a cohort of AYA aged 14-24 throughout the United States recruited from social media to target national benchmarks set by the American Community Survey. We used qualitative content analysis to analyze open-ended responses and summarized code frequency and demographic data with descriptive statistics. RESULTS: Of 826 AYAs, 666 responded to at least one question (response rate = 80.6 %) and the mean age of respondents was 19.9 years (SD = 2.3). We identified four themes from responses: (1) AYA believe cannabis is harmful during pregnancy, (2) they are divided on whether prenatal cannabis exposure should be considered child abuse or neglect, (3) they have mixed attitudes about safe parenting and regular cannabis use, and (4) they support counseling from health care professionals about prenatal cannabis use. CONCLUSIONS: AYAs were concerned about potential risks of prenatal cannabis exposure and want clinicians to counsel about cannabis use during pregnancy. More than one in three AYAs surveyed felt prenatal cannabis use should be classified as child abuse or neglect, in contrast to the declining perception of risk among pregnant people.

Lifestyle factors and subjective well­being among older adults in China: A national community-based cohort study.

There has been limited research on the relationship between health habits and subjective well-being (SWB) among Chinese oldest older adults. This study aims to explore lifestyle factors associated with SWB in this population. We analyzed data from three waves (2008-2014) of the CLHLS, including 28,683 older adults. Lifestyle factors analyzed included fruit and vegetable intake, smoking, alcohol consumption, physical exercise, and social participation. Results suggested that high frequency of fruit and vegetable intake, current and past physical exercise, and high levels of social participation were associated with increased SWB. SWB was lower in older adults who never smoked compared to persistent smokers and in those who never drank alcohol or ceased drinking compared to persistent drinkers. We encourage older adults to enhance SWB through increased fruit and vegetable intake, physical exercise, and social participation. However, quitting smoking and drinking may not necessarily improve SWB, particularly in the context of China.

The association between lower extremity function and cardiovascular diseases risk in older Chinese adults: Longitudinal evidence from a nationwide cohort.

BACKGROUND: Older adults in China are at a high risk of cardiovascular diseases (CVD), and impaired lower extremity function (LEF) is commonly observed in this demographic. This study aimed at assessing the association between LEF and CVD, thus providing valuable insights for clinical practice and public health policies. METHODS: A sample of 4,636 individuals was included from the China Health and Retirement Longitudinal Study (CHARLS) dataset. Logistic regression and cox proportional hazard regression model was utilized to study the association between LEF and CVD incidence. Cross-lagged panel models were utilized to investigate the potential causal association between LEF and CVD over time. RESULTS: Poor LEF was significantly associated with a higher risk of CVD in the total population [OR (95 % CI): 1.62 (1.27-2.05), P < 0.001]. Individuals with poor LEF demonstrated an increased risk of developing CVD [HR (95 % CI): 1.11 (1.02-1.23), P < 0.05], particularly stroke, compared to those with good LEF. And those with poor LEF had higher risks for heart disease [1.21 (1.00-1.45), P < 0.05] and stroke [1.98 (1.47-2.67), P < 0.001]. CONCLUSION: The results suggest the potential usefulness of the Short Physical Performance Battery (SPPB) for classifying stroke risk in older Chinese adults, which also suggested that preventing and/or improving LEF may be beneficial for reducing stroke incidence and promoting healthy aging for older adults.

Association between dynapenia and multimorbidity: A systematic review.

Dynapenia and multimorbidity are common health problems affecting older adults. However, few studies have systematically reviewed the association between dynapenia and multimorbidity. Therefore, this systematic review aimed to provide a comprehensive overview of studies on the association between these conditions. We searched four electronic databases for relevant articles published in July 2023. The main inclusion criteria were the following: (1) a description of dynapenia, which indicates loss of muscle strength and (2) a description of multimorbidity with two or more chronic diseases. Five studies met these inclusion criteria. In all five of these studies, the participants were community-dwelling older adults. All the studies showed an association between dynapenia and multimorbidity. The prevalence of dynapenia and multimorbidity ranged from 16% to 25.9%. The results of our systematic review demonstrated that dynapenia in older adults increases the risk of multimorbidity. We propose that interventions and reversible changes in dynapenia can prevent multimorbidity.

A randomized, double-blind, placebo-controlled study on immune improvement effects of ethanolic extract of Echinacea purpurea (L.) Moench in Korean adults.

Echinacea purpurea (L.) Moench (EP), a medicinal plant native to North America, is now cultivated in various regions including Europe. With increasing popularity of Echinacea in Korea recently, a human clinical trial was conducted to evaluate immune-enhancing efficacy and safety of EP 60% ethanolic extract (EPE) in Koreans. Eighty volunteers were recruited for this randomized, double-blind, placebo-controlled clinical trial. They were randomly divided into two groups and given either a daily dose of 200 mg of EPE or a placebo. All participants underwent testing for Natural Killer (NK) cell cytotoxic activity, serum cytokine levels (IL-2, IL-6, IL-10, IL-12, IFN-γ, TNF-α), Wisconsin Upper Respiratory Symptom Survey-21 (WURSS-21), and Multidimensional Fatigue Scale (MFS) during this study to assess changes in outcomes. After 8 weeks of EPE consumption, a significant increase in NK cell cytotoxic activity compared to the placebo was observed. Additionally, serum cytokine levels of IL-2, IFN-γ, and TNF-α also significantly increased following EPE consumption. However, no significant changes were observed in WURSS-21 and MFS before and after EPE consumption. Throughout the 8-week study period, no adverse reactions were reported in relation to EPE consumption, and there were no clinically significant changes in diagnostic laboratory tests or vital signs in the EPE group. These results indicate that consumption of EPE could lead to immune improvement without any adverse effects. This clinical trial was the first to demonstrate beneficial effects of EPE consumption on immunity in Korean adults.

Direct-to-consumer DNA testing: the perspectives and experiences of donor conceived young adults in the UK.

RESEARCH QUESTION: What meanings do donor conceived young adults give to direct-to-consumer DNA testing, and how does direct-to-consumer DNA testing relate to their lived experiences? DESIGN: Thirty-three young adults participated in in-depth interviews in November 2020 and September 2021 as part of a study of donor conceived people in the UK that focuses on the period of young adulthood. All participants were aged between 18 and 31 years, had been conceived by sperm donation at a time of legal donor anonymity, and were mainly resident in the UK. Interviews were analysed using reflexive thematic analysis. RESULTS: Nineteen participants (58%) had used at least one direct-to-consumer DNA test, and 14 (46%) had not. Three participants (9%) had learned about their donor conception inadvertently through a direct-to-consumer DNA test. Twelve participants (36%) had matched with their donor, someone conceived using the same donor, or both. Four related themes that capture participants' perspectives and experiences of direct-to-consumer DNA testing were identified: ruptures, disclosures, webs and temporalities. CONCLUSIONS: To the authors' knowledge, this is the first study to evidence both active interest and disinterest in direct-to-consumer DNA testing among individuals who are donor conceived. The meanings ascribed to, and uses of, direct-to-consumer DNA testing vary significantly among donor conceived young adults. Findings relating to the relationship between 'informal' and 'formal' information systems, and the absence of guidance and support for those using direct-to-consumer DNA tests, should be considered carefully by practitioners, regulatory bodies and policymakers going forward.

Protective Effects of ß-Blockers on Bone in Older Adults with Dementia.

Increased ß-adrenergic receptor activity has been hypothesized to cause bone loss in those with dementia. We investigated the effect of long-term ß-blocker use on rate of bone loss in older adults with dementia. We used a linear mixed-effects model to estimate the relationship between long-term ß-blocker use and rate of bone loss in participants from the Health Aging and Body Composition study. Records of 1198 participants were analyzed, 44.7% were men. Among the men, 25.2% had dementia and 20.2% were on ß-blockers, while in the women, 22.5% had dementia and 16.6% received ß-blockers. In the 135 men with dementia, 23 were taking ß-blockers, while 15 of 149 women with dementia were using ß-blockers. In men with dementia, ß-blocker users had 0.00491 g/cm2 less bone mineral density (BMD) loss per year at the femoral neck (i.e., 0.63% less loss per year) than non-users (p < 0.05). No differences were detected in women with or without dementia and men without dementia. ß-blockers may be protective by slowing down bone loss in older men with dementia.

Oral health status of institutionalized older adults receiving domiciliary dental care: A cross-sectional retrospective study.

AIM: This study aimed to evaluate the oral health of care-dependent institutionalized older adults receiving domiciliary dental care. METHODS AND RESULTS: Dental health records of institutionalized adults receiving regular domiciliary dental care were examined (observation period: 5 years). Relevant demographic and oral health information were extracted. Statistical analyses included descriptive and non-parametric tests (α = .05). Records of 398 nursing home residents (mean-age: 84.9 ± 6.4 years) were included. Average time spent by the residents in the institution was 2.8 ± 1.5 years. The mean number of teeth present and the overall DMF-T score was 14.7 ± 9.1 and 27.4 ± 6.2, respectively. The DMF-T score increased until the 3-year recall, with a significant increase in the number of decayed teeth (2-year: p = .013; 3-year: p = .010). An improvement in the residents' periodontal health was seen during the observation period but was not statistically significant. CONCLUSION: The findings of this cross-sectional study confirmed that regular domiciliary dental care provision to institutionalized older adults helps maintain gingival and periodontal health. However, the incidence of dental caries might still be a problem that needs to be addressed with effective measures that improve the daily oral care provision to these older adults.

Ischemic Stroke in Young Tunisian Adults.

INTRODUCTION: Ischemic Stroke in young adults is a real public health problem; it's a major cause of disability, alters quality of life and has a great socio-economic impact. AIM: determine risk factors and specify the etiology of arterial ischemic stroke in young Tunisian adults. METHODS: In this 5 years retrospective study (2015-2020), we included all young adults (18-50 years) admitted for arterial ischemic stroke (AIS). Risk factors were registered and analyzed. All patients were investigated using a standard protocol: biological tests, brain imaging, carotid ultrasound and cardiac assessment. Additional investigations were carried out at the discretion of the treating physician. The cause of ischemic stroke was classified according to the TOAST criteria. RESULTS: We collected 200 patients with AIS. The mean age was 41.37 years ± 6.99. Traditional vascular risk factors were observed in more than 1/4 patients. A definite cause of stroke was identified in 120 patients. Cardio-embolic causes were the most common among our patients (19%) followed by atherosclerosis of the large arteries (11.5%). Other determined etiologies were found in 27.5% of patients. The etiology remained unclear in 40% of cases: undetermined despite complete investigation in 17.5%, undetermined and incompletely investigated 14.5 % and more than one potential pathomechanisms in 8%. CONCLUSION: Through this study, we demonstrated the diversity of etiology of stroke in young Tunisian adults. Changes of lifestyle are responsible for the occurrence of the traditional risk factors at an early age. Rheumatic heart diseases remain a frequent cause of AIS in our area.
