RESUMEN
BACKGROUND: Psychological therapies can be effective in reducing symptoms of depression and anxiety in people living with dementia (PLWD). However, factors associated with better therapy outcomes in PLWD are currently unknown. AIMS: To investigate whether dementia-specific and non-dementia-specific factors are associated with therapy outcomes in PLWD. METHOD: National linked healthcare records were used to identify 1522 PLWD who attended psychological therapy services across England. Associations between various factors and therapy outcomes were explored. RESULTS: People with frontotemporal dementia were more likely to experience reliable deterioration in depression/anxiety symptoms compared with people with vascular dementia (odds ratio 2.98, 95% CI 1.08-8.22; P = 0.03) or Alzheimer's disease (odds ratio 2.95, 95% CI 1.15-7.55; P = 0.03). Greater depression severity (reliable recovery: odds ratio 0.95, 95% CI 0.92-0.98, P < 0.001; reliable deterioration: odds ratio 1.73, 95% CI 1.04-2.90, P = 0.04), lower work and social functioning (recovery: odds ratio 0.98, 95% CI 0.96-0.99, P = 0.002), psychotropic medication use (recovery: odds ratio 0.67, 95% CI 0.51-0.90, P = 0.01), being of working age (recovery: odds ratio 2.03, 95% CI 1.10-3.73, P = 0.02) and fewer therapy sessions (recovery: odds ratio 1.12, 95% CI 1.09-1.16, P < 0.001) were associated with worse therapy outcomes in PLWD. CONCLUSIONS: Dementia type was generally not associated with outcomes, whereas clinical factors were consistent with those identified for the general population. Additional support and adaptations may be required to improve therapy outcomes in PLWD, particularly in those who are younger and have more severe depression.

BACKGROUND: Depression is an important, potentially modifiable dementia risk factor. However, it is not known whether effective treatment of depression through psychological therapies is associated with reduced dementia incidence. The aim of this study was to investigate associations between reduction in depressive symptoms following psychological therapy and the subsequent incidence of dementia. METHODS: National psychological therapy data were linked with hospital records of dementia diagnosis for 119808 people aged 65+. Participants received a course of psychological therapy treatment in Improving Access to Psychological Therapies (IAPT) services between 2012 and 2019. Cox proportional hazards models were run to test associations between improvement in depression following psychological therapy and incidence of dementia diagnosis up to eight years later. RESULTS: Improvements in depression following treatment were associated with reduced rates of dementia diagnosis up to 8 years later (HR = 0.88, 95% CI 0.83-0.94), after adjustment for key covariates. Strongest effects were observed for vascular dementia (HR = 0.86, 95% CI 0.77-0.97) compared with Alzheimer's disease (HR = 0.91, 95% CI 0.83-1.00). CONCLUSIONS: Reliable improvement in depression across psychological therapy was associated with reduced incidence of future dementia. Results are consistent with at least two possibilities. Firstly, psychological interventions to improve symptoms of depression may have the potential to contribute to dementia risk reduction efforts. Secondly, psychological therapies may be less effective in people with underlying dementia pathology or they may be more likely to drop out of therapy (reverse causality). Tackling the under-representation of older people in psychological therapies and optimizing therapy outcomes is an important goal for future research.

Background: Little is known about what factors can modify the relationship between affective symptoms and cognitive function across the life course.Aim: To investigate a number of factors that can contribute to resilience in cognitive function in relation to affective symptoms, using data from the National Child Development Study.Subjects and methods: Adult affective symptoms were measured using the Malaise Inventory Scale (ages 23, 33, 42 and 50). Measures of immediate and delayed memory, verbal fluency and information processing accuracy (age 50) were used to derive measures of resilience in cognitive function-better than predicted cognition, when accounting for experiences of affective symptoms. Factors contributing to resilience in cognitive function were informed by a literature review and included sex, childhood cognitive ability, education, household socio-economic position (SEP), midlife SEP, and APOE genotype. Linear regression and structural equation modelling approaches were used for analyses.Results: Higher childhood cognitive ability, educational level, midlife SEP and female sex contributed to better than predicted cognitive function in relation to affective symptoms (i.e. resilience), with particularly consistent effects for memory. No effects on resilience were revealed for APOE genotype.Conclusion: Understanding factors contributing to resilience in cognitive function in those with affective symptoms can inform interventions to promote healthy cognitive ageing for those at risk.

BACKGROUND: Vaccination generating a robust memory population of CD8+ T cells may provide protection against cancer. However, immune therapies for cancer are influenced by the local tumour immune microenvironment. An infiltrate of T cells into tumours of people with colorectal cancer has proven to be a significant indicator of good prognosis. METHODS: We used an intracaecal mouse model of cancer to determine whether a protective immune response against a mucosal gut tumour could be generated using a systemic intervention. We investigated the generation of murine memory CD8+ T cells using a sustained antigen release vaccine vehicle (chitosan gel; Gel + OVA) containing the model antigen ovalbumin, chitosan gel alone (Gel) or conventional dendritic cell vaccination (DC + OVA) using the same protein antigen. RESULTS: Following vaccination with Gel + OVA, CD8+ T cell memory populations specific for ovalbumin protein were detected. Only vaccination with Gel + OVA gave decreased tumour burden compared to unvaccinated or DC + OVA-vaccinated mice in the intracaecal cancer challenge model. CONCLUSION: These results indicate that subcutaneous vaccination with Gel + OVA generates a population of functional CD8+ memory T cells in lymphoid tissue able to protect against intracaecal tumour challenge. Vaccination with chitosan gel may be valuable in anti-cancer treatment at both peripheral and mucosal sites.

BACKGROUND: Meta-analyses support an association between anxiety in older adulthood and dementia. The aim of this study was to use routinely collected health data to test whether treatment of anxiety disorders through psychological intervention is associated with a lower incidence of dementia. METHODS: In this prospective cohort study, data from nationally provided psychological therapy services in England termed Improving Access to Psychological Therapies from 2012 to 2019 were linked to medical records, including dementia diagnoses as defined by the tenth edition of the International Classification of Diseases, up to 8 follow-up years later. Inclusion criteria were as follows: (1) patients who were aged 65 years and older; (2) patients with a probable anxiety disorder; and (3) those with no previous or current diagnosis of dementia. Cox proportional hazards models were constructed to test whether reliable improvement in anxiety following psychological intervention was associated with future dementia incidence. The primary outcome was all-cause dementia and cases were identified using ICD-10 dementia codes from Hospital Episode Statistics, Mental Health Services Dataset, and mortality data. For main analyses, hazards ratios (HRs) are presented. FINDINGS: Data from 128â077 people aged 65 years and older attending a nationally provided psychological intervention service in England were linked to medical records. 88â019 (69·0%) of 127â064 participants with available gender data were women and 39â585 (31·0%) were men. 111â225 (95·9%) of 115â989 with available ethnicity data were of White ethnicity. The mean age of the sample was 71·55 years (SD 5·69). Fully adjusted models included data from 111â958 people after 16â119 were excluded due to missing data on key variables or covariates. 4510 (4·0%) of 111â958 participants had a dementia diagnosis. The remaining 107â448 (96·0%) were censored either at date of death or when the final follow-up period available for analyses was reached. People who showed reliable improvement in anxiety had lower rates of later dementia diagnosis (3·9%) than those who did not show reliable improvement (5·1%). Reliable improvement in anxiety following psychological intervention was associated with reduced incidence of all-cause dementia (HR 0·83 [95% CI 0·78-0·88]), Alzheimer's disease (HR 0·85 [0·77-0·94]), and vascular dementia (HR 0·80 [0·71-0·90]). Effects did not differ depending on anxiety disorder diagnosis. INTERPRETATION: Results showed that reliable improvement in anxiety from psychological therapy was associated with reduced incidence of future dementia. There are multiple plausible explanations for this finding and further research is needed to distinguish between these possibilities. Missing data in the sample limit reliability of findings.

BACKGROUND: Autistic adults report a higher prevalence of anxiety and depression than adults without identified autism but have poorer access to appropriate mental health care. Evidence-based psychological therapies are recommended in treatment guidelines for autistic adults, but no study has investigated their effectiveness in large samples representative of the autistic population accessing routine care. This study aimed to examine therapy outcomes for autistic adults in a primary care service. METHODS: In this retrospective, matched, observational cohort study of national health-care records, we used the MODIFY dataset that used linked electronic health-care records, including national data, for individuals who accessed psychological therapy in primary care in Improving Access to Psychological Therapies (IAPT) services in 211 clinical commissioning group areas in England, UK. All adults aged 18 years or older who had completed a course of IAPT in 2012-19 were eligible, and were propensity score matched (1:1) with a comparison group without identified autism. Exact matching was used, when possible, for a range of sociodemographic factors. Primary outcomes were routine metrics that have been nationally defined and used to evaluate IAPT treatments: reliable improvement, reliable recovery, and reliable deterioration. Secondary outcomes were calculated pre-post treatment changes in scores for Patient Health Questionnaire-9, Generalised Anxiety Disorder Assessment-7, and Work and Social Adjustment Scale measures. Subgroup analyses investigated differential effects across a range of sociodemographic factors. FINDINGS: Of 2â515â402 adults who completed at least two sessions of IAPT in 2012-19, 8761 had an autism diagnosis (5054 [57·7%] male and 3707 [42·3%] female) and 1â918â504 did not (631â606 [32·9%] male and 1â286â898 [67·0%] female). After propensity score matching, 8593 autistic individuals were matched with an individual in the comparison group. During IAPT treatment, symptoms of depression and generalised anxiety disorder decreased for most autistic adults, but symptoms were less likely to improve in the autism group than in the comparison group (4820 [56·1%] of 8593 autistic adults had reliable improvement vs 5304 [61·7%] of 8593 adults in the matched group; adjusted odds ratio [ORadj] 0·75, 95% CI 0·70-0·80; p<0·0001) and symptoms were more likely to deteriorate (792 [9·2%] vs 619 [7·2%]; ORadj 1·34, 1·18-1·48; p<0·0001). In the comparison group, improved outcomes were associated with employment and belonging to a higher socioeconomic deprivation category, but this was not the case for autistic adults. INTERPRETATION: Evidence-based psychological therapy for depression or anxiety might be effective for autistic adults but less so than for adults without identified autism. Treatment moderators appear different for autistic individuals, so more research is needed to allow for better targeted and personalised care. FUNDING: Alzheimer's Society.

Understanding factors associated with dementia risk is important for informing future interventions aimed at dementia prevention. There is accumulating evidence for the association between depression and risk of dementia, however less is known about the association between positive psychological factors and dementia incidence. This review aims to synthesise evidence regarding the association between positive psychological constructs (PPCs) and later risk of MCI and dementia in adults aged 50 and over. Literature searches were conducted in Medline, PsycINFO, and Scopus until March 2021. Papers reporting on the association between at least one PPC and later risk of MCI or dementia in people aged 50 + without cognitive impairment at baseline were included. Results from the meta-analyses revealed that purpose in life was significantly associated with a reduced risk of dementia (HR = 0.81, 95% CI [0.78, 0.85], p < .001), however results for positive affect were non-significant (HR = 0.94, 95% CI [0.76, 1.15], p = .54). Results for other PPCs are described narratively. Mixed findings for different PPCs highlight the importance of investigating these factors individually. Understanding which factors may play a protective role in their association with risk of mild cognitive impairment and dementia could have important implications for informing dementia prevention interventions.

AIM: To synthesise evidence regarding the association between positive psychological constructs (PPCs) and cognitive function in adults aged 50 +. METHODS: Literature searches: Medline, PsycINFO, and Scopus (inception to February 2022). Studies were included if they reported on the association between at least one PPC and one objective measure of cognitive function in people aged 50 + without cognitive impairment at baseline. Where at least two studies reported on the same PPC and cognitive outcome, estimates were pooled through meta-analysis. FINDINGS: In total, 37 studies were included. There was evidence of cross-sectional associations for 'meaning in life' (verbal fluency: b = 0.09, 95 %CI [0.07, 0.11], p < .001; memory: b = 0.10, 95 %CI [0.08, 0.12], p < .001), 'purpose in life' (verbal fluency: b = 0.07, 95 %CI [0.05, 0.08], p < .001; memory: r = 0.13, 95 %CI [0.08, 0.18], p < .001), and positive affect (cognitive state: r = 0.25, 95 %CI [0.14, 0.36], p < .001; memory: r = 0.05, 95 %CI [0.02, 0.08], p < .001) with various domains of cognitive function. However, no significant results were found for life satisfaction (p = .13) or longitudinal studies investigating positive affect and memory (p = .48). Other PPCs were included in narrative syntheses only. IMPLICATIONS: Purpose and meaning in life may be sensible primary targets for interventions to promote healthy cognitive aging. More longitudinal and causal inference research is needed to better understand this association and its implications for clinical practice.

Background: Depression and anxiety are common and deleterious in people living with dementia (PLWD). It is currently unknown whether routinely provided psychological therapy can help reduce these symptoms in PLWD. This study aimed to investigate improvements in depression and anxiety symptoms over the course of therapy offered in primary care psychological therapy services in PLWD and to compare outcomes to people without dementia. Methods: National data from Improving Access to Psychological Therapies services (IAPT) across England linked with Hospital Episode Statistics data, the Mental Health Services Dataset, and HES-ONS mortality data were used to identify 1,549 PLWD who completed a course of psychological treatment in IAPT between 2012-2019 and a propensity score matched control group without identified dementia. Outcome measures included pre-post intervention changes in depression (PHQ-9) and anxiety (GAD-7) symptoms and therapy outcomes (reliable improvement, recovery, deterioration). Findings: Symptoms of depression (t(1548)=31·05, p<·001) and anxiety (t(1548)=30·31, p<·001) improved in PLWD over the course of psychological therapy with large effect sizes (depression: d=-0·83; anxiety: d=-0·80). However, PLWD were less likely to reliably improve (OR=·75, 95%CI[·63,·88], p<·001) or recover (OR=·75, 95%CI[·64,·88], p=·001), and more likely to deteriorate (OR=1·35, 95%CI[1·03,1·78], p=·029) than a matched control sample without dementia. Interpretation: Psychological therapy may be beneficial for PLWD with depression or anxiety, but it is currently not as effective as for people without dementia. More research is needed to improve access to psychological therapies and to understand this discrepancy and how therapies can be adapted to further improve outcomes. Funding: This work was supported by the Alzheimer's Society.
RESUMEN
While widowhood is known to be associated with poorer physical and mental health outcomes, studies examining the association of widowhood with cognition have yielded mixed results. This review aimed to elucidate the link between widowhood and cognitive decline. A systematic search of Medline, Embase, PsycInfo, CINAHL and Scopus (until December 2020) was conducted to identify studies on the association between widowhood (vs. being married) and cognition in cognitively healthy adults aged 50 +. A cross-sectional meta-analysis (of 10 studies; n = 24,668) found a significant association of widowhood with cognition (g = - 0.36, 95% CI [- 0.47, - 0.25], p = < 0.001). Meta-regressions suggested that study design, cognitive domain measured, sample age, difference in mean age between widowed and married groups, and study continent did not account for observed heterogeneity. A longitudinal meta-analysis (of 3 studies; n = 10,378) found that the "continually widowed" group (from baseline to follow-up) showed significantly steeper declines in cognition compared to the "continually married" group (g = - 0.15, 95%CI [- 0.19, - 0.10], p = < 0.001). Findings indicate that widowhood may be a risk factor for cognitive decline. As there are no effective treatments for cognitive impairment, studying mechanisms by which widowhood might be associated with poorer cognition could inform prevention programs for those who have experienced spousal bereavement.

Background: Pharmacist-led vaccination that has the potential to ease the vaccination burden from general practitioners, is comparatively a newer service in New Zealand. However, to reap the maximum benefits out of this service, a consistent and effective promotion approach using various online platforms is indispensable. Objective: To identify what online information the general public can find about which pharmacies across NZ provide vaccination services. Methods: Every pharmacy in NZ was reviewed online to determine what vaccination information they advertised, then a sample of pharmacies were randomly selected from six District Health Boards (DHBs) to be called and confirm if the information they stated online was accurate. Results: Whilst the majority (more than 70%) of pharmacies did provide information about their services online, only 31% of the pharmacies had vaccination information on their websites, 20% on Healthpoint, and 13% had the information on social media. The telephonic survey revealed various information discrepancies in more than a quarter of the sample. Conclusions: A lack of online presence across multiple pharmacies is a pressing issue. Also, currently, NZ pharmacies do not have a very high online presence advertising vaccination services. Improving the amount and quality of this information is pertinent at this time as when COVID-19 vaccination drive may commence anytime, and the pharmacy sector will be well placed to conduct vaccinations on a large scale.
RESUMEN
BACKGROUND: Many patients choose to audio-record their medical consultations so that they can relisten to them at home and share them with family. Consultation audio-recordings can improve patients' recall and understanding of medical information and increase their involvement in decision making. A hospital-endorsed consultation audio-recording mobile app would provide patients with the permission and means to audio-record their consultations. The Theory of Planned Behavior provides a framework for understanding how patients can be encouraged to appropriately audio-record consultations. OBJECTIVE: The aim of this study was to use a co-design process to develop a consultation audio-recording mobile app called SecondEars. METHODS: App development began with stakeholder engagement, followed by a series of 6 co-design workshops and then user acceptance testing. Stakeholder engagement included advice from legal, information technology (IT), clinical and allied health leads; digital strategy; and medical records. he co-design workshops were attended by: patient consumers, members of the research team, IT staff, the app designers, clinicians, and staff from medical records. During workshops 1 to 4, the purpose and scope of the app were refined, possible pitfalls were addressed, and design features were discussed. The app designers then incorporated the results from these workshops to produce a wireframe mock-up of the proposed SecondEars app, which was presented for feedback at workshops 5 and 6. RESULTS: The stakeholders identified 6 requirements for the app, including that it be patient driven, secure, clear in terms of legal responsibilities, linked to the patient's medical record, and that it should require minimal upfront and ongoing resources. These requirements informed the scope of the co-design workshops. The workshops were attended by between 4 and 13 people. The workshop attendees developed a list of required features and suggestions for user interface design. The app developers used these requirements and recommendations to develop a prototype of the SecondEars app in iOS, which was then refined through user acceptance testing. CONCLUSIONS: The SecondEars app allows patients to have control and autonomy over audio-recording and sharing their consultations while maintaining privacy and safety for medical information and legal protection for clinicians. The app has been designed to have low upkeep and minimal impact on clinical processes. The SecondEars prototype is currently being tested with patients in a clinical setting.
RESUMEN
Hypoglycemia is a serious complication following treatment of hyperkalemia with intravenous insulin. The aims of this study were to determine the incidence of hypoglycemia (≤3.9 mmol/l, 70 mg/dL) and severe hypoglycemia (<3.0 mmol/l, 54 mg/dL) in noncritical care inpatients following treatment of hyperkalemia and to establish the risk factors predisposing to this complication. This was a single-center observational study reviewing the Electronic Patient Records of hyperkalemia treatment with intravenous insulin on the general wards of a large UK teaching hospital. A total of 662 episodes of hyperkalemia treated with insulin/dextrose were included. Among these episodes, 116 treatments (17.5%) resulted in hypoglycemia and 47 (7.1%) resulted in severe hypoglycemia. Lower pretreatment capillary blood glucose level, older age, and lower bodyweight were associated with a higher risk of posttreatment hypoglycemia. The incidence of hypoglycemia following hyperkalemia treatment in hospitalized patients is unacceptably high. Identifying individuals at high risk of hypoglycemia and adjusting prescriptions may reduce the incidence.

BACKGROUND: In Saskatoon in 2002, as one of the key strategies for the in motion health promotion strategy, the Forever...in motion program was developed with the general goal of increasing opportunities for physical activity among older adults living in congregate housing. The three components of the program were a low-intensity exercise program, informal socialization and educational sessions. The objective of the present study was to examine whether participation in this program positively influenced participants' physical, emotional, psychological and social well-being. METHODS: A quasi-experimental, pretest/post-test design was employed to examine the impact of the program on various aspects of participant well-being. Thirty-six program participants and a comparison group of 22 non-participants from two congregate housing facilities took part in the study. The pretest was administered to the study and comparison groups before or shortly after the 12-week session commenced, and the post-test was administered after the 12-week session had concluded. Pretest and post-test assessment consisted of self-report measures of (1) vitality, (2) self-rated health, 3) mental health, (4) social functioning, (5) role limitations due to emotional problems, 6) physical activity-related knowledge, and (7) self-efficacy for exercise. A multivariate analysis of covariance (MANCOVA) was conducted using the seven post-test scores as dependent variables and the pretest scores as covariates. RESULTS: After adjusting for differences in baseline characteristics, the findings revealed statistically significant improvements in self-reported health and self-efficacy for exercise in the program participant group as compared with non-participants. CONCLUSION: The results of this study suggest that a relatively low-cost, low-intensity exercise program such as the Forever...in motion program may positively influence the well-being of older adults living in congregate housing. However, additional research with a larger number of participants and a more rigorous study design is needed to further elucidate the health benefits of the Forever...in motion program.

Foot ulcers are a common complication in patients with diabetes. Negative pressure wound therapy (NPWT) is a wound care therapy that is being increasingly used in the management of foot ulcers. This article presents a systematic review examining the effectiveness of this therapy. The review question is how effective is NPWT in achieving wound healing in diabetes foot ulcers? The primary outcome for this study was the number of patients achieving complete wound healing (secondary outcomes, other markers of wound healing, adverse events and patient satisfaction). A systematic literature review and tabulative synthesis of randomised controlled trials (RCTs). The review identified four RCTs of weak to moderate quality. Only one study examining NPWT in postamputation wound healing reported data on the primary outcome. These data show a 20% improvement in wound healing [odds ratios = 2.0%, confidence interval (CI) -1.0 to 4.0] and number needed to treat = 6 (CI 4-64). No serious treatment-related complications were reported by any of the studies. One study suggested a reduction in the risk of secondary amputation (absolute risk reduction = 7.9%, CI 0.5-15.43). Studies also reported an increase in granulation and wound-healing rates in patients treated with NPWT therapy. No data on patient satisfaction or experience were reported. While all the studies included in the review indicated that the NPWT therapy is more effective than conventional dressings, the quality of the studies were weak and the nature of the inquiries in terms of outcome and patient selection divergent. There is a strong need for larger trials to assess NPWT therapy in diabetes care with different groups of patients and in relation to different clinical objectives and parameters.
