The combined effect of socioeconomic position and C-reactive protein for predicting incident cardiometabolic disease: Findings from a 14-year follow-up study of the English Longitudinal Study of Ageing (ELSA).

Cardiovascular disease and diabetes are leading causes of morbidity and mortality worldwide. Social inequalities in the distribution of these diseases across the population exist. The aim of the current study was to examine the additive effect of socioeconomic position and a known biological risk marker (C-reactive protein [CRP]) for future incident cardiometabolic disease. We used data from the English Longitudinal Study of Ageing (N = 5410). Tertiles of net financial wealth and CRP (>3 mg/L) were measured at wave 2 (2004/05) and disease incidence (coronary heart disease [CHD], stroke, diabetes/high blood glucose) was reported across the subsequent 14 years of follow-up (2006-2019). Individual diseases were modelled as well as cardiometabolic multimorbidity which was defined as 2 or more incident cardiometabolic disease diagnoses over follow-up. Participants were free from the disease of interest at baseline. Cox proportional hazard and logistic regression analyses were used controlling for sociodemographic, lifestyle and health-related covariates. After adjusting for all covariates, the combination of low wealth and elevated CRP was an independent predictor of incident diabetes/high blood glucose (Hazard Ratio (HR) = 2.14; 95% Confidence Interval (C.I.) = 1.49-3.07), CHD (HR = 2.48, 95% C.I. = 1.63-3.76), stroke (HR = 1.55; 95% C.I. = 1.18-2.04), relative to high wealth/low CRP. Low wealth and elevated CRP was also an independent predictor of incident cardiometabolic multimorbidity (Odds Ratio = 2.22, 95% C.I. = 1.16-4.28) in age and sex adjusted models. The presence of both low wealth and elevated CRP was implicated in the onset of CHD, stroke, diabetes/high blood glucose, and cardiometabolic multimorbidity up to 14 years later, reflecting the role of psychobiological processes in predicting disease burden. Our results reinforce calls for efforts to tackle structural inequalities to improve healthy ageing trajectories.

A systematic review of the clinical impact of small colony variants in patients with cystic fibrosis.

BACKGROUND: Cystic fibrosis (CF) is a life-limiting disorder that is characterised by respiratory tract inflammation that is mediated by a range of microbial pathogens. Small colony variants (SCVs) of common respiratory pathogens are being increasingly recognised in CF. The aim of this systematic review is to investigate the prevalence of SCVs, clinical characteristics and health outcomes for patients with CF, and laboratory diagnostic features of SCVs compared to non-small colony variants (NCVs) for a range of Gram-positive and Gram-negative respiratory pathogens. METHODS: A literature search was conducted (PubMed, Web of Science, Embase and Scopus) in April 2020 to identify articles of interest. Data pertaining to demographic characteristics of participants, diagnostic criteria of SCVs, SCV prevalence and impact on lung function were extracted from included studies for analysis. RESULTS: Twenty-five of 673 studies were included in the systematic review. Individuals infected with SCVs of Staphylococcus aureus (S. aureus) were more likely to have had prior use of the broad-spectrum antibiotic trimethoprim sulfamethoxazole (p < 0.001), and the prevalence of SCVs in patients infected with S. aureus was estimated to be 19.3% (95% CI: 13.5% to 25.9%). Additionally, patients infected with SCVs of Gram-negative and Gram-positive pathogens were identified to have a lower forced expiratory volume in one second percentage predicted (-16.8, 95% CI: -23.2 to -10.4) than those infected by NCVs. Gram-positive SCVs were commonly described as small and non-haemolytic, grown on Mannitol salt or blood agar for 24 h at 35°C and confirmed using tube coagulase testing. CONCLUSION: The findings of this systematic review demonstrate that SCVs of S. aureus have a high prevalence in the CF community, and that the occurrence of SCVs in Gram-positive and Gram-negative pathogens is linked to poorer respiratory function. Further investigation is necessary to determine the effect of infection by SCVs on the CF population.

"It's Still in the Test Tube and Finding out How the Experiment Ends ". A Qualitative Study on Health and Aging in Older Gay Males Living with HIV in England.

This paper highlights experiences and perceptions of older gay males living with Human Immunodeficiency Virus (HIV) in relation to age, sexual orientation, HIV status and how they perceive health. Participants were gay males aged 50 and over living in England, diagnosed with HIV for longer than 2 years. In total, 19 interviews were conducted between March 2020 and March 2021. Data were analysed using thematic analysis. Three major themes were generated: 1.) Health as holistic and as a balance; 2.) The impact of HIV on people's lives; 3.) The Intersectionality of stigma: a lifetime of discrimination. Participants highlighted the changing nature of the concept of health through their lifespan while the intersectionality of stigma in different contexts is examined considering the personal journey of living with HIV. The implications of health as a complex concept and intersectional stigma on the planning and delivering of care in this population are discussed.

Clustering of Cardiometabolic Risk Factors and Dementia Incidence in Older Adults: A Cross-Country Comparison in England, the United States, and China.

BACKGROUND: There is mixed evidence for an association between cardiometabolic risk factors and dementia incidence. This study aimed to determine whether different latent classes of cardiometabolic conditions were associated with dementia risk in older adults across England, the United States, and China. METHODS: A total of 4 511 participants aged 50 and older were drawn from the English Longitudinal Study of Ageing (ELSA), 5 112 from Health and Retirement Study (HRS), and 9 022 from China Health and Retirement Longitudinal Study (CHARLS). Latent class analyses were performed across each data set utilizing 7 baseline cardiometabolic conditions: obesity, low high-density lipoprotein cholesterol, systolic and diastolic blood pressure, hyperglycemia, diabetes, and inflammation. Confounder-adjusted Cox proportional hazards regressions were conducted to estimate dementia incidence by cardiometabolic latent classes. RESULTS: Three similar cardiometabolic classes were identified across all countries: (i) "relatively healthy/healthy obesity," (ii) "obesity-hypertension," and (iii) "complex cardiometabolic." Across the 3 samples, a total of 1 230 individuals developed dementia over a median of 6.8-12.2 years. Among ELSA and HRS participants, the "complex cardiometabolic" group had a higher dementia risk when compared to the "healthy obesity" groups (England: adjusted hazard ratio [AdjHR] = 1.62 [95% confidence interval {CI} = 1.11-2.37]; United States: AdjHR = 1.31 [95% CI = 1.02-1.68]). However, in CHARLS participants, the "obesity-hypertension" group had a greater risk of dementia when compared to the "relatively healthy" group (AdjHR = 1.28 [95% CI = 1.04-1.57]). CONCLUSION: This study provides evidence that in western populations, complex cardiometabolic clusters are associated with higher rates of dementia incidence, whereas in a Chinese sample, a different cardiometabolic profile seems to be linked to an increased risk of dementia.

Exceptional longevity in a lightly exploited, semi-anadromous clupeid (Perth herring Nematalosa vlaminghi) within a degraded estuarine environment.

Many anadromous (and semi-anadromous) fish species, which migrate from marine to freshwater ecosystems to spawn and to complete their life cycle, are currently threatened by habitat degradation in the upper parts of estuaries and rivers, where spawning and juvenile nursery areas occur. This situation pertains to Nematalosa vlaminghi, a semi-anadromous gizzard shad (Clupeidae: Dorosomatinae) endemic to south-western Australia. More information on the biology of N. vlaminghi is required for its effective management and conservation. This study estimated growth, longevity and natural mortality of N. vlaminghi. Ages were determined by counting validated annual growth increments in thin sections of sagittal otoliths. Fish were sampled in the Swan-Canning Estuary, which historically hosted the main commercial fishery for N. vlaminghi. Since the late 1990s, however, only very minor catches of this species have been taken from this estuary and none since 2007. Given the essentially unexploited state of the current population, the estimate of total mortality (Z, y-1 ) from the catch curve analysis in this study provides a direct estimate of natural mortality (M, y-1 ) for N. vlaminghi. Somatic growth during this study was substantially slower than that historically reported for N. vlaminghi. Various processes operating in this estuary since the 1970s may have contributed to slower growth, including increased hypoxia, higher primary productivity due to eutrophication and cessation of fishing for N. vlaminghi. The maximum observed age of 19.8 years for N. vlaminghi is the highest reported for any gizzard shad globally and one of the highest reported for any clupeid species. This exceptional longevity is likely part of a life-history strategy that allows N. vlaminghi, which exhibits substantial variation in annual recruitment success, to persist in the intermittently closed estuaries of south-western Australia where environmental factors, including low flow and hypoxia, can create unfavourable conditions for reproduction for extended periods.

The Association of Loneliness With Health and Social Care Utilization in Older Adults in the General Population: A Systematic Review.

BACKGROUND AND OBJECTIVES: Loneliness is proposed to be linked with increased service use. This review examined the association of loneliness and health and social care utilization (HSCU) in older adults from the general population. RESEARCH DESIGN AND METHODS: Four databases were screened for studies that examined the association of loneliness (predictor) with HSCU (outcome) in older adults (defined as the majority of sample 60 or older). Study quality was assessed with the National Institutes for Health scale for observational cohorts and cross-sectional studies. RESULTS: We identified 32 studies, of which 9 prospective studies were evaluated as being good or good-fair quality. Two good-fair quality studies found that loneliness at baseline was associated with subsequent admission to a residential care home. There was emerging evidence that loneliness was associated with emergency department use (n = 1) and cardiovascular disease-specific hospitalization (n = 1). Once adjusted for confounders, the highest quality studies found no association of baseline loneliness with physician utilization, outpatient service utilization, skilled nursing facility use, and planned or unplanned hospital admissions. The remaining studies were cross-sectional, or of fair to poor quality, and inadequate to reliably determine whether loneliness was associated with a subsequent change in HSCU. DISCUSSION AND IMPLICATIONS: There was heterogeneity in study design, measurement, and study quality. This generated an inconsistent evidence base where we cannot determine clear inferences about the relationship between loneliness and HSCU. Only one consistent finding was observed between 2 good-fair quality studies regarding care home admission. To determine clinical implications and make reliable inferences, additional good quality longitudinal research is needed.

Effect of Crizanlizumab, a P-Selectin Inhibitor, in COVID-19: A Placebo-Controlled, Randomized Trial.

COVID-19 is characterized by vascular inflammation and thrombosis, including elevations in P-selectin, a mediator of inflammation released by endothelial cells. We tested the effect of P-selectin inhibition on biomarkers of thrombosis and inflammation in patients with COVID-19. Hospitalized patients with moderate COVID-19 were randomly assigned to receive either placebo or crizanlizumab, a P-selectin inhibitor, in a double-blind fashion. Crizanlizumab reduced P-selectin levels by 89%. Crizanlizumab increased D-dimer levels by 77% and decreased prothrombin fragment. There were no significant differences between crizanlizumab and placebo for clinical endpoints. Crizanlizumab was well tolerated. Crizanlizumab may induce thrombolysis in the setting of COVID-19. (Crizanlizumab for Treating COVID-19 Vasculopathy [CRITICAL]; NCT04435184).

Risk of dementia in adults with cerebral palsy: a matched cohort study using general practice data.

OBJECTIVES: Determine the risk of incident dementia in adults with cerebral palsy (CP) compared with age, sex and general practice (GP) matched controls. DESIGN: Retrospective cohort study. SETTING: UK GPs linked into the Clinical Practice Research Datalink (CPRD). PARTICIPANTS: CPRD data were used to identify adults aged 18 or older with a diagnosis of CP. Each adult with CP was matched to three controls who were matched for age, sex and GP. In total, 1703 adults with CP and 5109 matched controls were included in the analysis. The mean baseline age of participants was 33.30 years (SD: 15.48 years) and 46.8% of the sample were female. PRIMARY OUTCOME: New diagnosis of dementia during the follow-up period (earliest date of 1987 to latest date of 2015). RESULTS: During the follow-up, 72 people were identified with a new diagnosis of dementia. The overall proportion of people with and without CP who developed dementia was similar (CP: n=19, 1.1%; matched controls n=54, 10.0%). The unadjusted HR suggested that people with CP had an increased hazard of being diagnosed with dementia when compared with matched controls (HR 2.69, 95% CI 1.44 to 5.00). This association was attenuated when CP comorbidities (sensory impairment, intellectual disability and epilepsy) were accounted for (HR 1.92, 95% CI 0.92 to 4.02). CONCLUSIONS: There was no difference in the proportion of people with CP and matched controls who were diagnosed with dementia during the follow-up. Furthermore, while there was evidence for an increased hazard of dementia among people with CP, the fact that this association was attenuated after controlling for comorbidities indicates that this association may be explained by comorbidities rather than being a direct result of CP. Findings should be interpreted with caution due to the low number of incident cases of dementia.

Social support and self-care outcomes in adults with diabetes: The mediating effects of self-efficacy and diabetes distress. Results of the second diabetes MILES - Australia (MILES-2) study.

AIMS: Diabetes self-care outcomes are positively impacted by social support. Understanding the mechanisms involved can inform more effective interventions. This study tested potential cross-sectional mediation of social support through self-efficacy and diabetes distress for self-care and clinical outcomes (diet, physical activity, blood glucose monitoring, HbA1c). METHOD: We analysed a sub-sample of the Australian Diabetes MILES-2 cross-sectional online survey (N = 1727). Measures were: Diabetes Social Support Scale, Confidence in Diabetes Self-care Scale, Problem Areas In Diabetes scale, diet and physical activity subscales of the Summary of Diabetes Self-Care Activities, and self-reported HbA1c. Separate mediation path models were tested for each of the four self-care/clinical outcomes in groups with type 1 and type 2 (insulin- and non-insulin-treated) diabetes. RESULTS: Social support was associated with more optimal self-care and self-reported HbA1c outcomes. When diabetes-specific self-efficacy and distress were included as mediators, the direct path from social support became non-significant. Conversely, the indirect effects of social support through diabetes-specific self-efficacy and distress were significant across all diabetes groups and outcomes. CONCLUSION: Diabetes-specific self-efficacy and distress may be important mechanisms linking social support with diabetes self-care and clinical outcomes. Social support interventions could explore whether improving diabetes self-efficacy and decreasing diabetes distress could help improve self-care.

The association between loneliness, social isolation and inflammation: A systematic review and meta-analysis.

The review synthesised evidence examining the association between a. loneliness with inflammation and b. social isolation with inflammation in adults aged 16 or older from the general population. From an initial 7,400 articles we identified 14 papers that examined loneliness, and 16 that examined social isolation. Qualitative syntheses indicated mixed results, variable study quality, and methodological heterogeneity. Most studies provided associations for C-reactive protein CRP, fibrinogen and Interleukin-6 IL-6, and these results were synthesised using random-effects meta-analyses. There was no association between loneliness with CRP or fibrinogen, but there was a significant association between loneliness and IL-6 for most-adjusted but not least-adjusted analyses. There was also a significant least-adjusted association between social isolation with CRP and fibrinogen, which remained significant for fibrinogen in most-adjusted analyses. There was no association between social isolation with IL-6. Sensitivity analyses indicated that methodological heterogeneity impacted on results. Results indicate that social isolation and loneliness could be linked with systemic inflammation, but more robust methodology is needed to confirm these associations and unpack mechanisms.

Modeling tails for collinear data with outliers in the English Longitudinal Study of Ageing: Quantile profile regression.

Research has shown that high blood glucose levels are important predictors of incident diabetes. However, they are also strongly associated with other cardiometabolic risk factors such as high blood pressure, adiposity, and cholesterol, which are also highly correlated with one another. The aim of this analysis was to ascertain how these highly correlated cardiometabolic risk factors might be associated with high levels of blood glucose in older adults aged 50 or older from wave 2 of the English Longitudinal Study of Ageing (ELSA). Due to the high collinearity of predictor variables and our interest in extreme values of blood glucose we proposed a new method, called quantile profile regression, to answer this question. Profile regression, a Bayesian nonparametric model for clustering responses and covariates simultaneously, is a powerful tool to model the relationship between a response variable and covariates, but the standard approach of using a mixture of Gaussian distributions for the response model will not identify the underlying clusters correctly, particularly with outliers in the data or heavy tail distribution of the response. Therefore, we propose quantile profile regression to model the response variable with an asymmetric Laplace distribution, allowing us to model more accurately clusters that are asymmetric and predict more accurately for extreme values of the response variable and/or outliers. Our new method performs more accurately in simulations when compared to Normal profile regression approach as well as robustly when outliers are present in the data. We conclude with an analysis of the ELSA.

Incidence of falls among adults with cerebral palsy: a cohort study using primary care data.

AIM: To compare the rate of falls between adults with and without cerebral palsy (CP). METHOD: We used primary care data on 1705 adults with CP and 5115 adults without CP matched for age, sex, and general practice attended. We compared odds of experiencing a fall between adults with and without CP using conditional logistic regression. We compared the rate of falls using a negative binomial model. RESULTS: Participants were 3628 males (53%) and 3192 females (47%) (median age 29y, interquartile range 20-42y) at the start of follow-up. Follow-up was 14 617 person-years for adults with CP and 56 816 person-years for adults without CP. Of adults with CP, 15.3% experienced at least one fall compared to 5.7% of adults without CP. Adults with CP had 3.64 times (95% confidence interval [CI] 2.98-4.45) the odds of experiencing a fall compared to adults without CP. The rate of falls was 30.5 per 1000 person-years and 6.7 per 1000 person-years for adults with and without CP respectively (rate ratio 5.83, 95% CI 4.84-7.02) INTERPRETATION: Adults with CP are more likely to fall, and fall more often, than adults without CP. The causes and consequences of falls in adults with CP need examination. WHAT THIS PAPER ADDS: Twenty adults with CP and 5.3 adults without CP experienced at least one fall per 1000 person-years. Adults with CP experienced 30.5 falls per 1000 person-years compared to 6.7 falls per 1000 person-years among adults without CP. Adults with CP had 3.64 times the odds of experiencing a fall compared to adults without CP. Adults with CP experienced 5.83 times more falls than adults without CP.

Noncommunicable disease among adults with cerebral palsy: A matched cohort study.

OBJECTIVE: To compare the incidence of noncommunicable diseases between adults with and without cerebral palsy (CP). METHODS: A cohort study was conducted using primary care data from the Clinical Practice Research Datalink. Cox models, stratified by matched set and adjusted for potential confounders, were fitted to compare the risk of any noncommunicable disease, cancer, cardiovascular disease, type 2 diabetes mellitus, and respiratory disease between adults with and without CP. RESULTS: The analysis included 1,705 adults with CP and 5,115 age-, sex-, and general practice-matched adults without CP. There was evidence from adjusted analyses that adults with CP had 75% increased risk of developing any noncommunicable disease compared to adults without CP (hazard ratio [HR] 1.75, 95% confidence interval [CI] 1.58-1.94). Specifically, they had increased risk of cardiovascular disease (HR 1.76, 95% CI 1.48-2.11) and respiratory disease (HR 2.61, 95% CI 2.14-3.19). There was no evidence of increased risk of cancer or type 2 diabetes mellitus. CONCLUSIONS: Adults with CP had increased risk of noncommunicable disease, specifically cardiovascular and respiratory disease. These findings highlight the need for clinical vigilance regarding identification of noncommunicable disease in people with CP and further research into the etiology and management of noncommunicable disease in this population.

Incidence of osteoarthritis, osteoporosis and inflammatory musculoskeletal diseases in adults with cerebral palsy: A population-based cohort study.

BACKGROUND: People with cerebral palsy (CP) may be at increased risk of musculoskeletal conditions due to various factors including malnutrition and abnormal levels of skeletal loading. This study aimed to compare the incidence of osteoporosis, osteoarthritis and inflammatory musculoskeletal diseases between adults with and without CP. METHODS: A population based cohort study was conducted using data from the Clinical Practice Research Datalink collected between 1987 and 2015. Adults with CP were matched to adults without CP for age, sex and general practice. Cox models, stratified by matched set and adjusted for potential confounders, were fitted to compare the risk of osteoporosis, osteoarthritis and inflammatory musculoskeletal diseases. RESULTS: 1705 adults with CP were matched to 5115 adults without CP. Adults with CP had an increased risk of osteoporosis in unadjusted (Hazard Ratio (HR) 3.67, 95% Confidence Interval (CI) 2.32 to 5.80, p < 0.001) and adjusted (HR 6.19, 95% CI 3.37 to 11.39, p < 0.001) analyses. No evidence of increased risk of inflammatory musculoskeletal diseases was observed in unadjusted or adjusted analyses. For osteoarthritis no evidence of increased risk was seen in the unadjusted analysis, but evidence of an increased risk was seen when the analysis was adjusted for alcohol consumption, smoking status, and mean yearly general practice (GP) visits (HR 1.54, 95% CI 1.17 to 2.02, p < 0.001). CONCLUSIONS: After accounting for potential confounding variables, we found that CP is associated with increased risk of osteoporosis and osteoarthritis. These findings provide the strongest epidemiological evidence to date for increased risk of osteoporosis and osteoarthritis in people with CP, and highlight need for clinical awareness of such conditions in this population.

Mortality due to cardiovascular disease, respiratory disease, and cancer in adults with cerebral palsy.

AIM: To compare mortality rates for cardiovascular disease, cancer, and respiratory disease between adults with cerebral palsy (CP) and the general population. METHOD: A cohort study was conducted using data from adults with CP in England, identified through a primary care data set (the Clinical Practice Research Datalink), with linked data on death registrations from the Office for National Statistics. Cause of death was categorized according to International Classification of Diseases codes. Standardized mortality ratios (SMRs) were calculated to compare mortality rates between adults with CP and the general population, adjusted for age, sex, and calendar year. RESULTS: Nine hundred and fifty-eight adults with CP were identified (52.5% males, 47.5% females; median age at start of follow-up 31y [interquartile range 22-43y]) and followed for a total of 7693 person-years. One hundred and forty-two patients (15%) died during follow-up. Adults with CP had an increased risk of death due to cardiovascular disease (SMR: 3.19, 95% confidence interval [CI] 2.20-4.62) and respiratory disease (SMR: 13.59, 95% CI 9.89-18.67), but not from malignant neoplasms (SMR: 1.42, 95% CI 0.83-2.45). INTERPRETATION: We found that adults with CP in England have increased risk of death due to diseases of the circulatory and respiratory systems, supporting findings from two studies that compared cause-specific mortality rates between adults with CP in the USA and the general population. Further research is required into primary and secondary prevention of cardiovascular and respiratory disease in people with CP worldwide. WHAT THIS PAPER ADDS: Adults with cerebral palsy (CP) in England have 14-fold increased risk of mortality due to diseases of the respiratory system. They have a 3-fold increased risk of mortality due to diseases of the circulatory system. Adults with CP had an increased risk of death due to cerebrovascular disease and ischaemic heart disease. The elevated risk of ischaemic heart disease, however, did not reach statistical significance at the 5% per cent level.

MORTALIDAD POR ENFERMEDAD CARDIOVASCULAR, ENFERMEDAD RESPIRATORIA Y CÁNCER EN ADULTOS CON PARÁLISIS CEREBRAL: OBJETIVO: Comparar tasas de mortalidad por enfermedad cardiovascular, cáncer y enfermedad respiratoria entre adultos con parálisis cerebral (PC) y la población general. MÉTODO: Se llevó a cabo un estudio de cohorte utilizando datos de adultos con PC en Inglaterra, identificados a través de un set de datos de atención primaria (the Clinical Practice Research Datalink) con datos vinculados sobre los registros de defunciones de la Oficina Nacional de Estadísticas. Las causas de muertes fueron categorizadas de acuerdo con los códigos de la Clasificación Internacional de Enfermedades. Las tasas de mortalidad estandarizadas (TME) fueron calculadas a fin de comparar las tasas de mortalidad entre adultos con PC y la población general, ajustadas por edad, sexo y año calendario. RESULTADOS: Se identificaron 958 adultos con PC (52,5% varones, 47,5% mujeres; edad mediana al comienzo del seguimiento 31 años [rango intercuartilo 22-43 años] y fueron seguidos por un total de 7.693 años-persona. Ciento cuarenta y dos pacientes (15%) fallecieron durante el seguimiento. Los adultos con PC tuvieron un mayor riesgo de muerte por enfermedad cardiovascular (TME:3,19, 95% intervalo de confidencia [IC] 2,20-4,62) y enfermedad respiratoria (TME:13,59,95% IC 9,89-18,67), pero no tuvieron mayor riesgo de neoplasias malignas (TME:1,42, 95% IC 0,83-2,45). INTERPRETACIÓN: Encontramos que los adultos con PC en Inglaterra tienen un riesgo incrementado de muerte por enfermedades de los sistemas circulatorio y respiratorio, sosteniendo los hallazgos con dos estudios que compararon tasas de mortalidad causa-específicas entre adultos con PC en los EEUU y la población general. Se necesita avanzar con la investigación hacia prevención primaria y secundaria de enfermedades cardiovascular y respiratoria en personas con PC en todo el mundo.

MORTALIDADE DEVIDO A DOENÇA CARDIOVASCULAR, RESPIRATÓRIA, E CÂNCER EM ADULTOS COM PARALISIA CEREBRAL: OBJETIVO: Comparar as taxas de mortalidade por doença cardiovascular, câncer, e doença respiratória em adultos com paralisia cerebral (PC) e a população em geral. MÉTODO: Um estudo de coorte foi realizado usando dados de adultos com PC na Inglaterra, identificados por meio de um conjunto de dados de atenção primária (o Datalink Pesquisa em Prática Clínica,), com dados sobre registros de óbitos do Escritório Nacional de Estatística. A causa da morte foi categorizada de acordo com os códigos da Classificação Internacional de Doenças. Taxas de mortalidade padronizadas (TMPs) foram calculadas para comparar as taxas de mortalidade entre adultos com PC e a população em geral, ajustadas por idade, sexo e ano calendário. RESULTADOS: Novecentos e cinquenta e oito adultos com PC foram identificados (52,5% do sexo masculino, 47,5% do sexo feminino; idade mediana no início do acompanhamento 31a [intervalo interquartil 22-43a]) e acompanhados por um total de 7,693 anos-pessoa. Cento e quarenta e dois pacientes (15%) morreram durante o acompanhamento. Adultos com PC tiveram risco aumentado de morte por doença (TMP: 3,19, intervalo de confiança [IC] a 95% 2,20-4,62) e doença respiratória (TMP: 13,59, IC 95% 9,89-18,67), mas não por neoplasias malignas (TMP: 1,42, IC 95% 0,83-2,45). INTERPRETAÇÃO: Observamos que adultos com PC na Inglaterra têm risco aumentado de more por doenças dos sistemas circulatório e respiratório, o que apóia achados de dois estudos qu compararam taxas de mortalidade causa-específica em adultos com PC nos EUA e na população em geral. Mais pesquisas são necessárias sobre a prevenção primária e secundária de doenças cardiovasculares e respiratórias em pessoas com PC em todo o mundo.

Risk of dementia associated with cardiometabolic abnormalities and depressive symptoms: a longitudinal cohort study using the English longitudinal study of ageing.

OBJECTIVES: Depression and cardiometabolic abnormalities are independently associated with a high risk of dementia. This study aimed to examine the association of comorbid depressive symptoms and cardiometabolic abnormalities with risk of dementia. METHODS: The sample comprised 4859 participants aged 50 or older without baseline dementia who took part in the English Longitudinal Study of Ageing (waves 2-7). Depressive symptoms were assessed using the Center for Epidemiologic Studies-Depression tool. Cardiometabolic abnormalities were defined as three or more cardiometabolic risk factors (inflammation, central obesity, raised triglycerides, low high-density lipoprotein [HDL] cholesterol, hypertension, and hyperglycaemia or diabetes). Participants were classified into four groups based on presence of depressive symptoms and cardiometabolic abnormalities. Results were analysed using the Cox proportional hazards regression adjusted for covariates. RESULTS: A total of 216 cases of incident dementia were reported over 10 years of follow-up. The group with high depressive symptoms only had an increased hazard of developing incident dementia during follow-up (HR = 2.68; 95%CI, 1.70-4.23), which was attenuated after adjustment for baseline cognition. No evidence was found for an association of overall cardiometabolic abnormalities with incident dementia; though hyperglycaemia, hypertension, and abdominal obesity with depressive symptoms had an unadjusted association with incident dementia. Only low-HDL cholesterol with depressive symptoms had an adjusted association with incident dementia (HR = 0.18; 95%CI, 0.04-0.75). CONCLUSIONS: This work confirms depressive symptoms as a risk factor for incident dementia. However, low HDL-cholesterol with depressive symptoms may be protective against dementia, though more work is required to confirm this association.

Risk of Depression and Anxiety in Adults With Cerebral Palsy.

Importance: Cerebral palsy (CP) is considered a pediatric condition despite most individuals with CP living into adulthood. Thus, there is a lack of evidence in adults with CP, which includes a paucity of research examining mental health in this population. Objectives: To determine the risk of depression and anxiety in adults with CP compared with an age-, sex-, and practice-matched reference group of adults without CP, using primary care data. Design, Setting, and Participants: Retrospective longitudinal cohort study set in UK primary care. Data were analyzed using Cox proportional hazards regression analyses adjusted for chronic conditions and visits to their physician. The study period ran from January 1987 to November 2015. Data of entry into the study ranged from January 1987 to September 2015. Data for 1705 adults 18 years or older with CP and 5115 matched adults without CP were extracted. Cerebral palsy was identified using diagnostic codes, and each person with CP was compared with 3 age-, sex-, and practice-matched controls. Exposures: Diagnosis of CP, with a second analysis accounting for comorbidity of intellectual disability (ID). Main Outcomes and Measures: Time to diagnosis for depression or anxiety following the date of entry into the study in adults with CP (with and without ID) compared with matched controls. Results: The mean (SD) age of the 1705 patients with CP and the 5115 adults without CP was 33.3 (15.5) years, and 798 participants (46.8%) were women. Individuals with CP had an increased adjusted hazard of depression (hazard ratio [HR], 1.28; 95% CI, 1.09-1.51) and anxiety (HR, 1.40; 95% CI, 1.21-1.63) compared with the matched reference group. When we accounted for ID comorbidity, there were 363 adults with CP who also had ID (mean [SD] age, 32.1 [13.2] years; 159 women [47.6%]) and 1342 adults with CP who did not have ID (mean [SD] age, 33.6 [16.1] years; 639 women [43.8%]). Only those individuals with CP and no comorbid ID had a higher risk of incident depression (HR, 1.44; 95% CI, 1.20-1.72) and anxiety (HR, 1.55; 95% CI, 1.28-1.87) than their matched controls. Conclusions and Relevance: Adults with CP have an increased risk of depression or anxiety. In particular, these results indicate that this association is driven largely by those individuals with CP with no co-occurring ID. Future work is needed in community-based samples to fully elucidate the causal mechanisms driving these associations.

A database of marine larval fish assemblages in Australian temperate and subtropical waters.

Larval fishes are a useful metric of marine ecosystem state and change, as well as species-specific patterns in phenology. The high level of taxonomic expertise required to identify larval fishes to species level, and the considerable effort required to collect samples, make these data very valuable. Here we collate 3178 samples of larval fish assemblages, from 12 research projects from 1983-present, from temperate and subtropical Australian pelagic waters. This forms a benchmark for the larval fish assemblage for the region, and includes recent monitoring of larval fishes at coastal oceanographic reference stations. Comparing larval fishes among projects can be problematic due to differences in taxonomic resolution, and identifying all taxa to species is challenging, so this study reports a standard taxonomic resolution (of 218 taxa) for this region to help guide future research. This larval fish database serves as a data repository for surveys of larval fish assemblages in the region, and can contribute to analysis of climate-driven changes in the location and timing of the spawning of marine fishes.

Deficits in temporal order memory induced by interferon-alpha (IFN-α) treatment are rescued by aerobic exercise.

Patients receiving cytokine immunotherapy with IFN-α frequently present with neuropsychiatric consequences and cognitive impairments, including a profound depressive-like symptomatology. While the neurobiological substrates of the dysfunction that leads to adverse events in IFN-α-treated patients remains ill-defined, dysfunctions of the hippocampus and prefrontal cortex (PFC) are strong possibilities. To date, hippocampal deficits have been well-characterised; there does however remain a lack of insight into the nature of prefrontal participation. Here, we used a PFC-supported temporal order memory paradigm to examine if IFN-α treatment induced deficits in performance; additionally, we used an object recognition task to assess the integrity of the perirhinal cortex (PRH). Finally, the utility of exercise as an ameliorative strategy to recover temporal order deficits in rats was also explored. We found that IFN-α-treatment impaired temporal order memory discriminations, whereas recognition memory remained intact, reflecting a possible dissociation between recognition and temporal order memory processing. Further characterisation of temporal order memory impairments using a longitudinal design revealed that deficits persisted for 10 weeks following cessation of IFN-α-treatment. Finally, a 6 week forced exercise regime reversed IFN-α-induced deficits in temporal order memory. These data provide further insight into the circuitry involved in cognitive impairments arising from IFN-α-treatment. Here we suggest that PFC (or the hippocampo-prefrontal pathway) may be compromised whilst the function of the PRH is preserved. Deficits may persist after cessation of IFN-α-treatment which suggests that extended patient monitoring is required. Aerobic exercise may be restorative and could prove beneficial for patients treated with IFN-α.

The association between C-reactive protein, Interleukin-6 and depression among older adults in the community: A systematic review and meta-analysis.

Previous research indicates there may be an association between inflammation and depression in older adults but results are inconsistent. Therefore, the aim of this review was to determine the cross-sectional and longitudinal associations of two inflammatory markers C-reactive protein (CRP) and Interleukin-6 (IL-6) with depression in older adults. We searched five databases for cross-sectional and longitudinal studies reporting an association between CRP or IL-6 with depression among adults sampled from the community aged 50 or older. We found 32 studies (23 cross-sectional, 7 longitudinal, and 2 assessing both cross-sectional and longitudinal associations) that met eligibility criteria. These studies were entered into a random-effects meta-analysis to determine the cross-sectional association and longitudinal direction of association between both IL-6 and CRP with depression. Results indicated a cross-sectional and longitudinal association between both CRP and IL-6 with depression in older adults, with inflammation leading to depression in longitudinal studies rather than depression to inflammation. However, there was notable heterogeneity between studies as results differed based on adjusting for confounders and on how inflammation and depression were measured. These sources of heterogeneity could explain differences in study results.
