RESUMEN

Background: Increased understanding of dementia risk-reduction and early detection of Alzheimer's disease and related disorders has spurred interest in the identification of risks for dementia, underlying putative biologies, or dementia itself. Implementation of such approaches require acceptability to the public. Research prior to 2012 indicated limited acceptability for population dementia screening. The changing landscape of dementia prevention research may influence recent perceptions. Additionally, perspectives from underserved populations, such as ethnic minorities and low socio-economic groups, are lacking. Objective: In this systematic review, we sought published studies since 2012 on attitudes and preferences of people with dementia, carers and the general public from ethnic minorities and low socio-economic groups regarding dementia screening. Methods: This review was preregistered on PROSPERO (CRD42023384115) and followed PRISMA guidelines. Key search terms were entered into five databases. Articles were included if they focused on population or risk screening for dementia via primary/community care-based assessments, and which included majority ethnic minority or low socio-economic groups or discretely considered these groups in data analysis. Data were synthesized narratively. Results: Seven studies reported perspectives of ethnic minorities regarding dementia screening; one study included people from low socio-economic groups. Results indicated that participants from ethnic minorities were willing to undergo dementia screening. Predictors of willingness included belief in benefits, desire to boost diversity, and to implement lifestyle changes. Unwillingness was associated with anxiety regarding results. Conclusions: Although there seems to be high acceptability for screening in the studied groups, more research is necessary to explore the practical considerations for screening such as cultural and economic barriers, trust, and post-screening actions.

RESUMEN

OBJECTIVES: To evaluate the feasibility and acceptability of a primary care-based intervention for improving post-diagnostic dementia care and support (PriDem), and implementation study procedures. DESIGN: A non-randomised, mixed methods, feasibility study. SETTING: Seven general practices from four primary care networks (PCNs) in the Northeast and Southeast of England. PARTICIPANTS: We aimed to recruit 80 people with dementia (PWD) and 66 carers INTERVENTION: Clinical Dementia Leads delivered a 12-month intervention in participating PCNs, to develop care systems, build staff capacity and capability, and deliver tailored care and support to PWD and carers. OUTCOMES: Recruitment and retention rates were measured. A mixed methods process evaluation evaluated feasibility and acceptability of the intervention and study procedures. Using electronic care records, researchers extracted service use data and undertook a dementia care plan audit, preintervention and postintervention, assessing feasibility of measuring the primary implementation outcome: adoption of personalised care planning by participating general practices. Participants completed quality of life, and service use measures at baseline, 4 and 9 months. RESULTS: 60 PWD (75% of recruitment target) and 51 carers (77% of recruitment target) were recruited from seven general practices across four PCNs. Retention rate at 9 months was 70.0% of PWD and 76.5% of carers. The recruitment approach showed potential for including under-represented groups within dementia. Despite implementation challenges, the intervention was feasible and acceptable, and showed early signs of sustainability. Study procedures were feasible and accessible, although researcher capacity was crucial. Participants needed time and support to engage with the study. Care plan audit procedures were feasible and acceptable. CONCLUSIONS: The PriDem model is an acceptable and feasible intervention. A definitive study is warranted to fully inform dementia care policy and personalised dementia care planning guidance. Successful strategies to support inclusion of PWD and their carers in future research were developed. TRIAL REGISTRATION NUMBER: ISRCTN11677384.

RESUMEN

Methylphenidate has an established role in the management of attention-deficit hyperactivity disorder and attentional deficit secondary to brain injury. Increasingly, methylphenidate is considered for the attentional deficit in paediatric brain tumour survivors. A small number of studies have explored the benefit of methylphenidate in this population; however, studies are of short duration and do not address the impact of medium to long-term use of methylphenidate on intellectual function. We identified six patients who are survivors of a paediatric brain tumour aged 12-18 years with greater than three years of use of methylphenidate for inclusion in a clinical case series. We used this patient cohort to identify key questions to inform a future long-term cohort study. Linear mixed model and reliable change index analyses were performed on the data. Reliable change index analyses showed benefits to working memory (n = 3), processing speed (n = 2), and full-scale IQ (n = 4) performance for some patients. This exploratory case series suggests the potential medium to long-term benefit of methylphenidate in brain tumour survivorship, indicating the need for larger, appropriately powered studies. These patient data, alongside a discussion of learning points from our previously published studies, are used as a conduit for the identification of questions relating to the use of methylphenidate in a paediatric brain tumour.

RESUMEN

INTRODUCTION: The Test of Everyday Attention for Children 2 (TEA-Ch 2) is a rigorously tested measure of attention, often used in pediatric neuro-oncology settings. Data from one Primary Treatment Centre found a high proportion of children scored in the highest range on the Cerberus subtest. This brief report attempts to answer the question: Does the Cerberus subtest of the TEA-Ch 2 provide outlying scores in the pediatric neuro-oncology population? METHODS: Data representing 62 Cerberus assessments from four primary treatment centers were analyzed. RESULTS: Data showed a substantially higher level of performance on the Cerberus subtest compared to other TEA-Ch2 subtests. Scores were not only higher than expected relative to children's performance on other subtests but also higher than would be expected in the general population. DISCUSSION: Within our data, performance on the Cerberus subset of the TEA-Ch 2 yields somewhat questionable data from which to draw conclusions regarding sustained attentional ability in a pediatric neuro-oncology cohort.

RESUMEN

OBJECTIVE: Fatigue is a chronic and debilitating symptom of many long-term neurological conditions (LTNCs). Although methylphenidate provides some promise in alleviating fatigue in other clinical groups, little work has explored its potential utility within LTNCs. The current systematic review and meta-analysis evaluates the utility of methylphenidate for symptoms of fatigue in LTNCs. METHODS: Five databases (PsycINFO, MEDLINE, Embase, Scopus, and Cochrane Library) were searched for relevant articles from their inception to February 2022. A purpose-developed evaluation tool was used to assess each study's research quality (QuEST:F). RESULTS: Of the 1698 articles identified, 11 articles were included within this review (n = 370). Meta-analytical findings reported an overall significant benefit of methylphenidate for symptoms of fatigue across a mixed neurological sample ( g = -0.44; 95% confidence interval, -0.77 to -0.11). Subgroup analyses identified a significantly greater benefit ( P < 0.001) of methylphenidate for fatigue in LTNCs with static pathogenic trajectories (eg, traumatic brain injury) (number needed to treat = 2.5) compared with progressive conditions (eg, multiple sclerosis) (number needed to treat = 40.2). CONCLUSIONS: Methylphenidate may pose an effective intervention for the treatment of fatigue in a number of LTNCs. Nonetheless, given the quality of the current evidence base, there exists a clear need for further robust assessment of the utility of methylphenidate-with a focus on subgroup-specific variability.

RESUMEN

Continued advancements in the treatment of pediatric brain tumors have resulted in a growing proportion of children surviving previously incurable diagnoses. However, survivors of pediatric brain tumors show reduced Health-Related Quality of Life (HRQoL) compared to healthy populations and non-CNS childhood cancer survivors. This review systematically evaluates the existing literature on the influence of supratentorial and infratentorial brain tumor locations on Health-Related Quality of Life outcomes in survivors of pediatric brain tumors. Five electronic databases were searched for relevant articles published between their inception and January 2022. A purpose-developed evaluative tool was constructed to assess the quality of eligible studies. 16 of the 5270 identified articles were included in this review (n = 1391). This review found little evidence relating to the impact of brain tumor location on HRQoL, with only one study finding a significant difference between supratentorial and infratentorial tumor survivors. Key limitations of the current evidence include poor statistical reporting, ambiguous construct definitions, and insufficient adjustment for confounds. Findings from this review show that recovery from a pediatric brain tumor extends beyond recovery post-treatment and that further study into the factors influencing survivor HRQoL, including the influence of tumor location, is necessary.

RESUMEN

BACKGROUND: Survivors of childhood CNS tumors are at a significant risk of chronic and multifaceted neurocognitive late effects. Recent findings indicate the potential utility of methylphenidate in addressing neurocognitive and academic plateauing and improving quality-of-life outcomes in this clinical population. However, the prescription of methylphenidate in neuro-oncology services remains inconsistent. OBJECTIVE: To explore the neurocognitive assessment and rehabilitative interventions (including the use of methylphenidate) offered to survivors of childhood CNS tumors within mainland UK. METHOD: We used a semi-structured questionnaire to gather qualitative data from clinical psychologists and neuropsychologists within National Health Service pediatric neuro-oncology principal treatment centers (PTCs) during May 2018. Thematic analytical methods were used to explore themes within the collected data. RESULTS: Eleven (58%) of the 19 PTCs returned the completed questionnaire. Respondents reported inadequate resource of psychology in many pediatric neuro-oncology PTCs, which limited the provision of methylphenidate to a restricted proportion of the patient group (i.e., those with the most profound neurocognitive difficulties). Respondents reported an interest in exploring the utility of methylphenidate in their patient group yet described a lack of appropriate evidence of its efficacy. In addition, respondents highlighted the need for the provision of accessible research summaries and treatment protocols addressing the use of methylphenidate. CONCLUSION: We anticipate that national collaboration between clinicians and researchers working in the cancer survivorship field will support the advancement of interventions such as methylphenidate for the growing clinical population of survivors of childhood CNS tumors.

RESUMEN

Whilst an increasing number of children survive previously incurable cancers of the central nervous system (CNS), associated treatments often result in significant neurocognitive late effects. Methylphenidate provides some signs of alleviating cognitive difficulties in different pediatric groups; however, a minimal amount of systematic work has explored its effectiveness isolated to vulnerable attentional domains. The current review aimed to explore the effectiveness of methylphenidate isolated to two attentional domains (sustained and selective attention)-with an aim to substantiate its utility in childhood cancer survivors. Five databases were comprehensively searched for relevant articles. A purpose-developed tool was used to assess each study's robustness and research quality. Eleven out of 1,865 identified articles were included within the review. Studies drew upon five clinical populations. Individual attentional domains demonstrate variation in their response to methylphenidate. Sustained attention demonstrated the most consistent benefit of methylphenidate, reported largely in attention-deficit/hyperactivity disorder (ADHD) groups. Gains in selective attention and higher-order cognitive functions appeared to follow initial gains in sustained attention. Childhood cancer survivors report greater gains in selective attention compared to sustained attention. Higher doses may yield greater benefit for children with more diffuse attentional deficits. There is a need to improve the validity of current attentional measures before further methylphenidate trials are conducted.

RESUMEN

Impairment in sustained attention is a common consequence of childhood Acquired Brain Injury (ABI). Whilst methylphenidate provides promise in enhancing "attention" as a unitary construct, little work has explored its effectiveness upon individual attentional domains. The current systematic review and meta-analysis evaluates the utility of methylphenidate on sustained attentional performance across childhood ABI groups. Five databases (PsycINFO, MEDLINE, Embase, Scopus & Cochrane Library) were searched for relevant articles from their inception to March 2022. A purpose-developed evaluation tool was used to assess each study's research quality (QuEST:MAP). Nine of the 1600 identified articles were included within this review (n = 259). Meta-analytical findings reported an overall significant benefit of methylphenidate on sustained attention in childhood ABI (g = -0.33, 95% CI: -0.62 to -0.04). Associated summary effect sizes were relatively small, particularly when adjusting for outlier cases. Subgroup analyses identified a significantly greater benefit of methylphenidate in clinical subgroups with comorbid ADHD diagnoses (p < .01). The current evidence base is characterized by small-scale clinical trials with variable research quality and low generalizability. Further robust research is needed to quantify methylphenidate utility upon individual attentional domains in larger and more representative ABI samples.

RESUMEN

Large urban trees have many benefits. However, falling branches pose a serious hazard to both people and infrastructure. In several tree species, aerial roots grow down from branches to the ground. These roots are capable of thickening to support the branches, lessening the risk of tree failure. Unfortunately, in urban environments most aerial roots die before reaching the ground. Here, we report a new method for encouraging aerial roots to reach the ground, developed by the second-year botany class at UNSW Sydney. Our class tested three experimental treatments on aerial roots of Ficus rubiginosa Desf. ex Vent. (Port Jackson Fig)-PVC pipes filled with sphagnum moss, PVC pipes filled with potting mix, and PVC pipes filled with sphagnum moss and topped with funnels to catch extra rainwater. All three treatments significantly improved aerial root growth, with 26 of the 30 (87%) treatment roots reaching the ground after one year compared to 0 of the 10 control roots. Our method was successful for roots up to 3 m above the ground, suggesting the potential growth rate of aerial roots is substantial when conditions are favourable. Our novel approach is an attractive and cost-effective alternative to slings and other artificial supports. This project is an example of using undergraduate practical classes to teach science while simultaneously addressing important real-world problems.

RESUMEN

A 25-year-old pregnant American Quarter Horse mare presented with a 1-week history of progressively worsening vaginal discharge. Transrectal ultrasound revealed increased thickness of the combined uterus and placenta with evidence of chorioallantoic edema but no placental separation. A thickened amnion was visible on transabdominal ultrasound. Abortion occurred 2 days after presentation despite medical treatment. At necropsy, the chorioallantois had variable but diffuse thickening with focally extensive browning of the chorionic surface in the right horn and adjacent body. There were fluid-filled sacculations on the allantoic surface of the umbilical cord, allantoamnion, and chorioallantois associated with diffuse perivascular fluid microscopically. A nonbranching acid-fast bacterium identified as belonging to the genus Mycobacterium Runyon group IV was isolated from the chorioallantois and uterine fluid. Ziehl-Neelsen stain confirmed the presence of intracellular acid-fast bacilli in trophoblasts of the gravid horn and the cervical star area. The current case is unique in that the mycobacteria did not initiate a significant granulomatous inflammatory response in the chorion unless villar necrosis occurred. Sequence analysis of the 16S ribosomal RNA gene and the rpoß gene, encoding the ß subunit of RNA polymerase, indicated that the strain of mycobacteria isolated in this case belonged to a novel species of rapidly growing mycobacteria and not to an established species. Mycobacteria are an uncommon and sporadic cause of placentitis and abortion, but should be suspected in cases of chronic placentitis that are not restricted to the cervical star area.
