RESUMO

There are currently many online resources for medical education during residency and beyond in anesthesiology, intensive care, pain, emergency and palliative medicine. From traditional textbooks and in-person events to learning platforms, apps, podcasts, simulation training and even virtual reality, there are many ways to supplement traditional residency curricula and continuing medical education. The coronavirus disease 2019 (COVID-19) pandemic has been instrumental in making medical education content more accessible and, among other things, accelerate the transfer of knowledge.To include all colleagues in the goal of life-long learning using these modern tools, we recommend the development of a digital media concept that is individually tailored to each department of anesthesiology. First, the goals of the department should be defined, e.g., can existing teaching materials be made more digitally accessible for asynchronous learning? Then, department resources should be compiled, e.g., what learning platforms are already being used and if and how social media should play a role? One or more persons should be named responsible and maintain the new concept. In this context, it is essential to develop quality criteria to properly assess the digital content.With the support of the department, conventional teaching methods can be combined with new digital possibilities in residency education and beyond. In this way, individual shift models, various levels of participation in live teaching events and different types of learners can be taken into account. These diverse digital tools can enrich the training and further education of every team member in an anesthesiology department and will accompany us well into the future.

RESUMO

Background: Research indicates an inconsistent relationship between age and the prevalence of premature ejaculation (PE), with studies reporting an increase, decrease, or no change with age. Aim: To reexamine the possible relationship between age and PE prevalence, implementing methodological improvements that enhance the likelihood of detecting real effects. Methods: From a sample of 2772 men, we analyzed a subset of 418 classified as having probable or definite PE based on the Premature Ejaculation Diagnostic Tool. We not only analyzed men with lifelong PE (LPE; n = 316) and acquired PE (APE; n = 102) separately but assessed prevalence differences across age groups using an omnibus measure to establish PE status and specific PE diagnostic criteria, individually and in multifactorial combination. Outcome: Prevalence of PE in younger vs older men. Results: LPE, but not APE, showed age-related differences in prevalence, with LPE being lower in the higher age group. This pattern was most discernible when a multifactorial approach was used to establish PE status. Clinical Translation: Older men may be less distressed about their dysfunction or may benefit from diminishing ejaculatory function with age. Strengths and Limitations: This cross-sectional study used an improved methodology to detect age-related differences in PE prevalence. Future studies would benefit from a larger sample size that enables a breakdown of prevalence using a greater number of age categories. Conclusion: According to an improved methodology, men with LPE showed a decline in prevalence with aging. A methodology aimed at exploring this relationship should-at the very least-not only distinguish between LPE and APE subtypes but also consider using a multifactorial method of determining PE status that includes a measure of bother/distress.

RESUMO

Introduction: Recently, Google introduced Pathways as its next-generation AI architecture. Pathways must address three critical challenges: learning one general model for several continuous tasks, ensuring tasks can leverage each other without forgetting old tasks, and learning from multi-modal data such as images and audio. Additionally, Pathways must maintain sparsity in both learning and deployment. Current lifelong multi-task learning approaches are inadequate in addressing these challenges. Methods: To address these challenges, we propose SEN, a Sparse and Expandable Network. SEN is designed to handle multiple tasks concurrently by maintaining sparsity and enabling expansion when new tasks are introduced. The network leverages multi-modal data, integrating information from different sources while preventing interference between tasks. Results: The proposed SEN model demonstrates significant improvements in multi-task learning, successfully managing task interference and forgetting. It effectively integrates data from various modalities and maintains efficiency through sparsity during both the learning and deployment phases. Discussion: SEN offers a straightforward yet effective solution to the limitations of current lifelong multi-task learning methods. By addressing the challenges identified in the Pathways architecture, SEN provides a promising approach for developing AI systems capable of learning and adapting over time without sacrificing performance or efficiency.

RESUMO

BACKGROUND: While several studies in cerebral amyloid angiopathy (CAA) focus on cognitive function, data on neuropsychiatric symptoms (NPS) and lifelong mental activities in these patients are scarce. Since NPS are associated with functional impairment, faster cognitive decline and faster progression to death, replication studies in more diverse settings and samples are warranted. METHODS: We prospectively recruited n = 69 CAA patients and n = 18 cognitively normal controls (NC). The number and severity of NPS were assessed using the Alzheimer's Disease (AD) Assessment Scale's (ADAS) noncognitive subscale. We applied different regression models exploring associations between NPS number or severity and group status (CAA vs. NC), CAA severity assessed with magnetic resonance imaging (MRI) or cognitive function (Mini-Mental State Examination (MMSE), ADAS cognitive subscale), adjusting for age, sex, years of education, arterial hypertension, AD pathology, and apolipoprotein E status. Mediation analyses were performed to test indirect effects of lifelong mental activities on CAA severity and NPS. RESULTS: Patients with CAA had 4.86 times (95% CI 2.20-10.73) more NPS and 3.56 units (95% CI 1.94-5.19) higher expected NPS severity than NC. Higher total CAA severity on MRI predicted 1.14 times (95% CI 1.01.-1.27) more NPS and 0.57 units (95% CI 0.19-0.95) higher expected NPS severity. More severe white matter hyperintensities were associated with 1.21 times more NPS (95% CI 1.05-1.39) and 0.63 units (95% CI 0.19-1.08) more severe NPS. NPS number (MMSE mean difference - 1.15, 95% CI -1.67 to -0.63; ADAS cognitive mean difference 1.91, 95% CI 1.26-2.56) and severity (MMSE - 0.55, 95% CI -0.80 to -0.30; ADAS cognitive mean difference 0.89, 95% CI 0.57-1.21) predicted lower cognitive function. Greater lifelong mental activities partially mediated the relationship between CAA severity and NPS (indirect effect 0.05, 95% CI 0.0007-0.13), and greater lifelong mental activities led to less pronounced CAA severity and thus to less NPS (indirect effect - 0.08, 95% CI -0.22 to -0.002). DISCUSSION: This study suggests that NPS are common in CAA, and that this relationship may be driven by CAA severity. Furthermore, NPS seem to be tied to lower cognitive function. However, lifelong mental activities might mitigate the impact of NPS in CAA.

RESUMO

Background: Recent genetic association studies focusing on central pathways have been performed to investigate the correlation between susceptibility alleles and the risk of lifelong premature ejaculation (LPE). However, there remains a dearth of documented genes associated with peripheral pathways. Objective: In this study we aimed to investigate the relationship between single nucleotide polymorphisms (SNPs) associated with the peripheral genes CYP19A1, CYP1A1, and CYP1A2 and the risk of LPE. Methods: From August 2017 to August 2020, a total of 511 participants (139 LPE patients and 372 controls) were recruited. Trained medical professionals diagnosed LPE according to the standard definition set by the International Society for Sexual Medicine. Nine candidate SNPs were chosen and genotyped using the MassARRAY system. Allele and genotype frequencies of the SNPs among patients and controls were compared using the χ2 test. Logistic regression analysis, adjusted for age, was performed to calculate odds ratios (ORs) and 95% confidence intervals (CIs) using PLINK version 1.9. Haploview software was employed to analyze linkage disequilibrium and haplotype distribution. The interaction among candidate SNPs concerning LPE risk was evaluated using multifactor dimensionality reduction. The relationship between selected polymorphisms and specific features was assessed using analysis of variance. Outcome: Heterozygous SNPs located in the CYP19A1 (rs4646, rs17601876), CYP1A1 (rs1048943), and CYP1A2 (rs762551, rs2470890) genes showed significant correlations with the risk of LPE. Results: The findings of this study confirmed that heterozygous SNPs in the CYP19A1 (rs4646 AC vs CC: OR, 1.84; CI, 1.10-3.09; rs17601876 AG vs GG: OR, 1.80; CI, 1.06-3.05) and CYP1A1 genes (rs1048943 CT vs TT: OR, 1.71; CI, 1.02-2.87), respectively, can significantly increase the LPE risk. Participant scores for the Premature Ejaculation Diagnostic Tool (P =.002) and International Index of Erectile Function-5 (P =.020) differed significantly by genotype for the different genotypes of CYP1A1-rs1048943. Haplotype analysis revealed strong linkage disequilibrium under CYP1A2_rs762551-rs2470890 (D' = 1.00). Clinical Implications: The findings of this and other investigations of genetic determinants and potential pathogenic mechanisms of LPE may advance diagnostic and therapeutic opportunities in LPE patients. Strengths and Limitations: In this study of LPE in men with CYP gene variants we addressed a current research gap. However, data on risk factors such as smoking and drinking were incomplete in both the case and control groups. In future studies we will expand the sample size and enhance data on risk factors for more precise assessments. Conclusion: In summary, polymorphisms in the peripheral genes CYP19A1, CYP1A1, and CYP1A2 may play a role in LPE among Chinese men of the Han population.

RESUMO

BACKGROUND/OBJECTIVES: The aim of this study was to evaluate the effects of lifelong team handball/football training on regional bone health and body composition in elderly women. METHODS: Seventeen elderly women team handball/football players (65.9 ± 5.7 years) and twenty-one untrained age-matched women (controls) (67.7 ± 5.1 years) participated. Whole-body and regional dual-energy X-ray absorptiometry scans of arms, legs, and lower spine (L1-L4) were performed. RESULTS: We observed 8% and 9% higher bone mineral density (BMD) and bone mineral content (BMC), respectively, at the whole-body level and in the legs and 11.5% higher BMC in the legs in team handball/football players compared to untrained age-matched controls (p < 0.05). Higher total and leg lean body mass (p < 0.05), along with lower total body fat percentage (p < 0.05) and higher T- and Z-scores, markers of fragility risk fracture (0.294 ± 1.461 vs. -0.538 ± 1.031; 1.447 ± 1.278 vs. 0.724 ± 0.823, respectively), were also found in team handball/football players compared to controls (p < 0.05). No significant differences in nutritional habits were observed between groups. CONCLUSIONS: Our study suggest that the beneficial effects of lifetime handball/football practice on bone preservation in elderly women occur independently from nutritional intake, which emphasize the potential role of team sports in osteoporosis prevention. Future studies should focus on the cofounding factors and causative mechanisms mediated by team sport practice in osteoporosis prevention.

RESUMO

Introduction: While it is well-established that follow-up care programs play a crucial role in preventing and early detecting secondary health conditions (SHCs) in persons with spinal cord injury [SCI, including spina bifida (SB)], the availability of evidence-based follow-up care programs remains limited. Under the leadership of the German-speaking Medical Society for Paraplegiology (DMGP), we have developed an evidence based clinical practice guideline for follow-up care of SHCs in persons with SCI and identify research gaps. Methods: This guideline was developed in accordance with the regulations of the Association of the Scientific Medical Societies in Germany (AWMF e.V.). To ensure an evidence-based guidance, we utilized the International Classification of Functioning, Disability and Health (ICF) generic core set and ICF Core Set for individuals with SCI in long-term context as our foundational framework. We conducted a comprehensive literature review to identify existing recommendations for follow-up care and graded the level of evidence according to relevant instruments. Subsequently, we formulated recommendations and achieved consensus through a structured nominal group process involving defined steps and neutral moderation, while adhering to the criteria outlined in the German guideline development instrument (DELBI). Results: Although there is a fair number of literatures describing prevalence and severity of SHCs after SCI, the amount of literature including recommendations was low (19 for SCI and 6 for SB). Based on the current evidence on prevalence and severity of SHCs and available recommendations, a clinical practice guideline on follow-up care of most relevant SHCs was defined. The recommendations for follow-up care are described in the following chapters: (1) Nervous system; (2) (Neuropathic) pain; (3) Cardiovascular diseases; (4) Respiratory System; (5) Immunological system, vaccination and allergies; (6) Gastrointestinal tract and function; (7) Endocrinological system and nutrition; (8) Urogenital system; (9) Contraception, pregnancy, birth and postpartum care; (10) Musculoskeletal system; (11) Pressure injuries; (12) Psychological health; (13) Medication and polypharmacy. Conclusion: We could successfully establish an evidence based clinical practice guideline for follow-up care of SHCs in individuals with SCI. There is however a notable lack of high-quality recommendations for SCI follow-up care.

RESUMO

BACKGROUND: Self-directed learning is a required skill for medical students for remaining lifelong learners. This study focuses on measuring the readiness for self-directed learning of basic sciences medical students. MATERIALS AND METHOD: In the second half of 2022, a descriptive cross-sectional study was conducted on 288 basic sciences medical students at Tabriz University of Medical Sciences in Iran. The students were selected using convenience sampling. The instrument used was Fisher's self-directed learning readiness (SDLR) scale consisting of "self-management", "desire for learning", and "self-control" domains. The data were analyzed by SPSS-25 and also by using descriptive statistics [mean, standard deviation (SD), median, frequency, and percentage] and inferential statistics techniques (Chi-square test and t-test, ANOVA, and MANOVA). Statistical significance was set at P < 0.05. RESULT: The results revealed that the scores of 63.9% students were more than 150. Also, the mean total score of self-directed learning readiness was 152.98 (SD = 16.76), suggesting that the self-directed learning readiness of the students was high level. The highest score was for "self-control" (59.99 ± 6.95), followed by "desire for learning" (46.99 ± 5.64) and "self-management" (46.01 ± 7.07). The total SDLR score and its three sub-scales did not show any notable interdependence with student contextual factors (age, gender, marital and residential status). However, a higher cumulative grade point average (>17) showed a significant higher mean in the "self-management" domain of SDLR among medical students (F = 3.730; P = 0.025). CONCLUSION: To become life-long learners, self-directed learning is crucial for medical students. The basic sciences medical students participating in this study showed a high level of SDL readiness. Even though the students obtained the highest score for the self-control sub-scale, the desire for learning and self-management skills needs further improvement, which can be achieved through multi-disciplinary approaches.

RESUMO

Background This study aims to evaluate the performance of ChatGPT in the medical specialization exam (MSE) that medical graduates take when choosing their postgraduate specialization and to reveal how artificial intelligence-supported education can increase the quality and academic success of medical education. The research aims to explore the potential applications and advantages of artificial intelligence in medical education and examine ways in which this technology can contribute to student learning and exam preparation. Methodology A total of 240 MSE questions were posed to ChatGPT, 120 of which were basic medical sciences questions and 120 were clinical medical sciences questions. A total of 18,481 people participated in the exam. The performance of medical school graduates was compared with ChatGPT-3.5 in terms of answering these questions correctly. The average score for ChatGPT-3.5 was calculated by averaging the minimum and maximum scores. Calculations were done using the R.4.0.2 environment. Results The general average score of graduates was a minimum of 7.51 in basic sciences and a maximum of 81.46, while in clinical sciences, the average was a minimum of 12.51 and a maximum of 80.78. ChatGPT, on the other hand, had an average of at least 60.00 in basic sciences and a maximum of 72.00, with an average of at least 66.25 and a maximum of 77.00 in clinical sciences. The rate of correct answers in basic medical sciences for graduates was 43.03%, while for ChatGPT was 60.00%. In clinical medical sciences, the rate of correct answers for graduates was 53.29%, while for ChatGPT was 64.16%. ChatGPT performed best with a 91.66% correct answer rate in Obstetrics and Gynecology and an 86.36% correct answer rate in Medical Microbiology. The least successful area for ChatGPT was Anatomy, with a 28.00% correct answer rate, a subfield of basic medical sciences. Graduates outperformed ChatGPT in the Anatomy and Physiology subfields. Significant differences were found in all comparisons between ChatGPT and graduates. Conclusions This study shows that artificial intelligence models such as ChatGPT can provide significant advantages to graduates, as they score higher than medical school graduates. In terms of these benefits, recommended applications include interactive support, private lessons, learning material production, personalized learning plans, self-assessment, motivation boosting, and 24/7 access, among a variety of benefits. As a result, artificial intelligence-supported education can play an important role in improving the quality of medical education and increasing student success.

RESUMO

BACKGROUND: Universal parenting campaigns are efficient, cost-effective and can eliminate barriers to accessing conventional, face-to-face parenting interventions. The aims of the CHAMPP4KIDS study were to assess Canadian early childhood providers' perceptions of the acceptability and feasibility of implementing a universal parenting resource, the Parenting for Lifelong Health tip sheets. METHODS: Using a convergent mixed method design, an online survey of providers working with families with young children in Ontario, Canada was followed by focus group discussions with a subset of providers to explore their perceptions of using the tip sheets in their professional practice. RESULTS: Providers generally perceived the tip sheets to be acceptable but had reservations with respect to the feasibility of distributing the sheets to their clients as standalone, universal parenting resources. Providers agreed the tip sheets covered topics pertinent to caregivers' concerns, offered useful strategies and, therefore, had the potential to be valuable, engaging resources for families. However, many providers said the sheets would only be effective as complementary resources to facilitated in-person sessions, especially for high-needs families. CONCLUSION: Providers suggested that future iterations of these resources take into consideration more accessible design and formatting, literacy levels, word choice and further cultural adaptation. Insight into the nuances and potential divergence between provider perceptions of universal materials' acceptability and feasibility can help adapt materials to pre-emptively respond to potential implementation barriers, facilitate intervention fidelity and, ultimately, increase the likelihood of intervention acceptability and feasibility of both providers and caregivers.

RESUMO

BACKGROUND: The current cutoff values of intravaginal ejaculation latency time for diagnosing lifelong premature ejaculation do not always match clinical practice, and the inconsistency in the cutoff values of intravaginal ejaculation latency time among different definitions has also posed challenges to both clinical management and research of premature ejaculation. OBJECTIVES: To re-evaluate the intravaginal ejaculation latency time and to find evidence-based cut-off values for diagnosing lifelong premature ejaculation that can be widely accepted and match clinical practice. MATERIALS AND METHODS: We addressed the flaws of previous studies. Lifelong premature ejaculation was diagnosed based on both patient self-report of premature ejaculation status and scores on the Premature Ejaculation Diagnostic Tool, with a control group consisting of non-premature ejaculation individuals included for comparison. Utilizing receiver operating characteristic curve analysis, the optimal self-estimated cutoff value for intravaginal ejaculation latency time in diagnosing lifelong premature ejaculation was determined. RESULTS: A total of 307 heterosexual participants (mean age = 30.7 ± 6.4) were included, comprising 187 lifelong premature ejaculation patients (mean age = 28.0 ± 4.6) and 120 non-premature ejaculation individuals (mean age = 35.0 ± 6.5). 2.7% of lifelong premature ejaculation patients experienced anteportal ejaculation. 59.9%, 92%, and 97.9% of lifelong premature ejaculation patients displayed intravaginal ejaculation latency times within 1, 2, and 3 min, respectively. The receiver-operating characteristic curve's area under the curve was 0.996 with a 95% confidence interval of 0.991-1.000 (p < 0.0001). The perceived intravaginal ejaculation latency time cut-off at 3.5 (sensitivity = 97.9%, specificity = 99.2%) showed the highest Youden index compared with other options. DISCUSSION: Although we found that 92.0% of lifelong premature ejaculation patients had a perceived intravaginal ejaculation latency time within 2 min, a perceived intravaginal ejaculation latency time cutoff value of less than 3.5 min for diagnosing lifelong premature ejaculation could encompass a larger proportion (97.9%) of patients seeking medical help for complaints of PE, and increasing the perceived intravaginal ejaculation latency time cutoff value to 3.5 min would not significantly increase the false-positive rate. CONCLUSION: The perceived intravaginal ejaculation latency time cutoff value for diagnosing lifelong premature ejaculation within a clinical practice context is 3.5 min.

RESUMO

INTRODUCTION: The Accreditation Council for Pharmacy Education (ACPE) defines continuing professional development (CPD) as a self-directed, ongoing, systematic, and outcomes-focused approach to lifelong learning that is applied into practice. Hospitals and health systems can use the ACPE CPD framework for performance evaluation and to support staff in developing learning goals. METHODS: This was an exploratory study using cross-sectional surveys and pharmacist self-reported CPD data at a community health system in the Southeastern USA. Surveys evaluating perceived value and use of CPD were administered to pharmacists with descriptive statistics calculated for quantitative survey responses qualitative data from open-ended responses analyzed using content analysis. CPD goals within pharmacist CPD records were reviewed and categorized based on relevance to the pharmacist's current practice setting. Survey results and CPD data were compared using an integrative narrative discussion. RESULTS: Overall, fifty-seven (33.1%) pharmacists and twelve (85.7%) pharmacy managers and directors responded to surveys. A total of 13 (22.8%) respondents strongly agreed and 21 (36.8%) respondents agreed that using CPD goals to advance their practice increased job enjoyment and 13 (22.8%) respondents strongly agreed and 30 (52.6%) respondents agreed that achievement of CPD goals resulted in improved patient care. A total of 3 (23.1%) managers or directors strongly agreed and 6 (46.2%) agreed that pharmacists are more engaged employees when they use a CPD framework to plan and achieve goals. Additionally, 3 (23.1%) strongly agreed and 7 (53.8%) agreed that using a CPD process for staff development contributed to retention. A total of 1353 CPD goals were documented by 148 pharmacists with 86.3% of goals rated as relevant to practice and 204 (15.1%) containing all specific, measurable, attainable, relevant, and time-bound (SMART) goal components. CONCLUSIONS: The CPD framework may be a useful approach to support pharmacist development in hospital and health system settings and facilitate performance reviews.

RESUMO

The COVID-19 pandemic has underscored the growing importance of digital technologies for economic resilience, especially for vulnerable groups like older workers in the informal sector. However, barriers to access and digital literacy create challenges alongside potential opportunities, particularly in less developed countries such as Ghana. Using older adults over 50 years engaged in informal work in Kumasi's Central Business District in Ghana as a case, this paper explores older informal workers' use of digital technologies in Ghana during the pandemic. Findings suggest that older informal workers relied heavily on their mobile phones as the only critical technological tool to sustain their businesses during the COVID-19 pandemic. However, the findings also reveal critical gaps in skills, training, and support, alongside resourcefulness in leveraging digital tools for business continuity. Key policy implications include expanding mobile-centric digital literacy programs, addressing infrastructure divides, and integrating capacity building into social protection. The paper contributes insights on strengthening lifelong learning and extending the working lives of older persons in the informal sector in the post-COVID era.

RESUMO

Pre-trained models are commonly used in Continual Learning to initialize the model before training on the stream of non-stationary data. However, pre-training is rarely applied during Continual Learning. We investigate the characteristics of the Continual Pre-Training scenario, where a model is continually pre-trained on a stream of incoming data and only later fine-tuned to different downstream tasks. We introduce an evaluation protocol for Continual Pre-Training which monitors forgetting against a Forgetting Control dataset not present in the continual stream. We disentangle the impact on forgetting of 3 main factors: the input modality (NLP, Vision), the architecture type (Transformer, ResNet) and the pre-training protocol (supervised, self-supervised). Moreover, we propose a Sample-Efficient Pre-training method (SEP) that speeds up the pre-training phase. We show that the pre-training protocol is the most important factor accounting for forgetting. Surprisingly, we discovered that self-supervised continual pre-training in both NLP and Vision is sufficient to mitigate forgetting without the use of any Continual Learning strategy. Other factors, like model depth, input modality and architecture type are not as crucial.

RESUMO

Background: Fetal alcohol spectrum disorder (FASD) is a common developmental disability that requires lifelong and ongoing support but is often difficult to find due to the lack of trained professionals, funding, and support available. Technology could provide cost-effective, accessible, and effective support to those living with FASD and their caregivers. Objective: In this review, we aimed to explore the use of technology available for supporting people living with FASD and their caregivers. Methods: We conducted a scoping review to identify studies that included technology for people with FASD or their caregivers; focused on FASD; used an empirical study design; were published since 2005; and used technology for assessment, diagnosis, monitoring, or support for people with FASD. We searched MEDLINE, Web of Science, Scopus, Embase, APA PsycINFO, ACM Digital Library, JMIR Publications journals, the Cochrane Library, EBSCOhost, IEEE, study references, and gray literature to find studies. Searches were conducted in November 2022 and updated in January 2024. Two reviewers (CZC and HW) independently completed study selection and data extraction. Results: In total, 17 studies exploring technology available for people with FASD showed that technology could be effective at teaching skills, supporting caregivers, and helping people with FASD develop skills. Conclusions: Technology could provide support for people affected by FASD; however, currently there is limited technology available, and the potential benefits are largely unexplored.

RESUMO

INTRODUCTION: Lifelong premature ejaculation (LPE) is a subtype of premature ejaculation. Genetic research on LPE has primarily focused on neurotransmitters such as serotonin, dopamine, and norepinephrine, whereas LPE treatment studies have focused on drugs such as selective serotonin reuptake inhibitors. However, findings from genetic association and pharmacotherapeutic studies have been inconsistent. OBJECTIVES: To provide a quality overview of neurobiological targets that are potentially associated with LPE by investigating genetic association and pharmacotherapeutic studies. METHODS: This scoping review was conducted per the PRISMA-ScR tool (Preferred Reporting Items for Systematic Reviews and Meta-analyses Extension for Scoping Reviews). Five databases were searched in March 2023 without timeline- or language-related restrictions. RESULTS: After deduplication, 3949 records were obtained for review. Following screening and full-text review with citation tracking, 52 studies were included: 18 genetic and 34 pharmacotherapy studies. Serotonergic targets, such as the serotonin transporter and pre- and postsynaptic serotonergic receptors, were most often associated with LPE in genetic and pharmacotherapeutic studies. Mixed results were found among polymorphisms within genetic studies. This mechanism is in accordance with pharmacotherapeutic studies, as the highest efficacy was found for potent serotonergic antidepressants. Successful treatment was also observed with medication acting on phosphodiesterase-5 enzyme, such as tadalafil and vardenafil. Analyses of other genetic association studies did not yield any further evidence for associated targets. CONCLUSIONS: This review is the first comprehensive scoping review on LPE. We found that serotonergic targets are most often associated with LPE, suggesting that the serotonergic pathway is a predisposing factor in LPE. Furthermore, there is some evidence for phosphodiesterase 5 inhibitors, which should be investigated. Other previously investigated neurobiological targets appear less likely to contribute to LPE. Future studies should focus on multiple targets, ideally in a genome-wide association study design.This review has been registered with the Open Science Framework (doi:10.17605/OSF.IO/JUQSD).

RESUMO

OBJECTIVE: This study aimed to investigate the impact of lifelong exercise, including both moderate-intensity continuous training and high-intensity interval training, on blood lipid levels and mental behaviour in naturally ageing mice to identify effective exercise strategies for ageing-related health issues. METHODS: Six-week-old male BALB/c mice were randomly assigned to one of four groups: young control (YC), natural ageing control (OC), lifelong moderate-intensity continuous exercise (EM), and lifelong high-intensity interval exercise (EH) groups. The EM group was trained at a speed corresponding to 70 % of the maximum running speed, while the EH group was trained at a running speed alternating between 50 % of the maximum running speed, 70 % of the maximum running speed, and 90 % of the maximum running speed. All exercise sessions were conducted three times per week, with each session lasting 50 min. Behavioural tests and blood sample collection were conducted at 72 weeks of age. RESULTS: Ageing in mice led to changes in muscle and fat mass. Both the EM and EH groups showed greater muscle mass and lower fat mass than did the OC group. Ageing was associated with elevated anxiety (fewer open arm entries, time spent in the central region) and depression (lower sucrose preference) indicators. However, these changes were reversed in both exercise groups, with no differences between the two exercise groups. Blood lipid levels, including total cholesterol (TC), total triglycerides (TGs), low-density lipoprotein (LDL), and free fatty acid (FFA) levels, were greater in the OC group than in the YC group. Additionally, the OC group exhibited lower high-density lipoprotein (HDL) levels. However, both the EM and EH groups exhibited improved lipid profiles compared to those of the YC group. CONCLUSION: Lifelong exercise, whether moderate-intensity continuous or high-intensity interval training, can preserve body health during ageing, prevent anxiety and depression, and maintain stable blood lipid levels. Both exercise types are equally effective, suggesting that exercise intensity may not be the critical factor underlying these beneficial adaptations.

RESUMO

BACKGROUND AND OBJECTIVES: Existing literature highlights notable health and social inequalities for people aging with a lifelong disability and the need for research to better understand how we can support this group to age well. This scoping review mapped existing literature related to "aging well" in people with lifelong disabilities. RESEARCH DESIGN AND METHODS: Five scientific databases and gray literature sources were searched for studies related to "aging well" and "lifelong disability" (defined as a disability that a person had lived with since birth or early childhood). RESULTS: We identified 81 studies that discussed aging well with a lifelong disability, with most (70%) focusing on intellectual disabilities. Two themes captured existing research on aging well with a lifelong disability: (1) framing aging well with a lifelong disability, which included the ways that people with lifelong disability, their supporters, and existing research frame aging well for this group and (2) supporting people to age well with a lifelong disability, which involves the micro-, meso-, and macro-level factors where research suggests interventions to facilitate aging well could be situated. DISCUSSION AND IMPLICATIONS: This synthesis highlights how aging well is currently framed in the literature and where interventions to improve aging well in this group could be situated. Literature highlights the importance of considering multilevel interventions to improve aging well. Evidence gaps include the lack of research conducted with groups other than those with intellectual disabilities and the need for more research examining aging well interventions.
