Ideología y ciencia del castigo en el retraso mental

En este artículo se analiza el conflicto existente entre aquel/os que contemplan las intervenciones terapéuticas aversivas desde un punto de vista ideológico y aquellos que lo hacen desde una perspectiva científica. Se ha dedicado especial atención al estudio más detallado que, sobre procedimientos punitivos para casos de retraso mental existe, y que fue realizado desde una perspectiva ideológica; se trata de una monografía de Guess, Helmstetter, Turnbull y Knowlton publicada en 1986 por la "Asociación para Personas con Incapacidades Severas" (The Association for Persons With Severe Handicaps). Dicha monografía adolece de una serie de defectos graves de índole conceptual y metodológica que impiden que las conclusiones de la misma puedan servir de fundamento a la investigación y a la política social en el campo del retraso mental. Se ha llegadoa la conclusión de que algunos de los que rechazan las intervenciones terapéuticas aversivas, lo hacen debido a que poseen un conocimiento limitado de la ciencia conductual y parten de un marco de referencia fundamentalmente ideológico

Tendo como base modelos de prática diagnóstica implementados em outros países, o objetivo do artigo é oferecer uma revisão geral acerca do que vem a ser o transtorno autista e dos fatores críticos que devem ser considerados durante o processo diagnóstico. São discutidos aspectos dos critérios diagnósticos e também das comorbidades, incidência, etiologia e diretrizes para a prática diagnóstica. Tais diretrizes incluem formas de exploração de sintomas de risco durante exames de rotina realizados por profissionais que trabalham com a população infantil e elementos básicos necessários para a realização de uma avaliação minuciosa e criteriosa por uma equipe interdisciplinar. Isso inclui, por exemplo, o uso de instrumentos específicos auxiliares no diagnóstico, elementos importantes para a avaliação médica e psicológica e encaminhamentos para serviços adequados de intervenção e apoio.Based on diagnostic models implemented in other countries, the goal of the article is to offer a general overview about autistic disorder and highlight some critical elements to be taken into account during the diagnostic process. We discuss aspects regarding the diagnostic criteria, as well as regarding comorbidities, incidence, etiology, and some practical guidelines for determining a diagnosis. Such guidelines include the critical aspects to be considered when screening the risk for autism in early childhood population and for a careful and comprehensive evaluation by a specialized interdisciplinary team. A comprehensive evaluation consists of the use of specific tools to help determine the diagnosis, some crucial elements for the medical and psychological evaluation, and the referral to adequate intervention and support services.Teniendo como base modelos de práctica diagnóstica implementados en otros países, el objetivo del artículo es ofrecer una revisión general acerca de lo que viene a ser el trastorno autista y de los factores críticos que deben ser considerados durante el proceso diagnóstico.

Atopic eczema in adulthood and mortality: UK population–based cohort study, 1998-2016

BACKGROUND: Atopic eczema affects up to 10% of adults and is becoming more common globally. Few studies have assessed whether atopic eczema increases the risk of death. OBJECTIVE: We aimed to determine whether adults with atopic eczema were at increased risk of death overall and by specific causes and to assess whether the risk varied by atopic eczema severity and activity. METHODS: The study was a population-based matched cohort study using UK primary care electronic health care records from the Clinical Practice Research Datalink with linked hospitalization data from Hospital Episode Statistics and mortality data from the Office for National Statistics from 1998 to 2016. RESULTS: A total of 526,736 patients with atopic eczema were matched to 2,567,872 individuals without atopic eczema. The median age at entry was 41.8 years, and the median follow-up time was 4.5 years. There was limited evidence of increased hazard for all-cause mortality in those with atopic eczema (hazard ratio = 1.04; 99% CI = 1.03-1.06), but there were somewhat stronger associations (8%-14% increased hazard) for deaths due to infectious, digestive, and genitourinary causes. Differences on the absolute scale were modest owing to low overall mortality rates. Mortality risk increased markedly with eczema severity and activity. For example, patients with severe atopic eczema had a 62% increased hazard (hazard ratio = 1.62; 99% CI = 1.54-1.71) for mortality compared with those without eczema, with the strongest associations for infectious, respiratory, and genitourinary causes. CONCLUSION: The increased hazards for all-cause and cause-specific mortality were largely restricted to those with the most severe or predominantly active atopic eczema. Understanding the reasons for these increased hazards for mortality is an urgent priority

Patterns of Atopic Eczema Disease Activity from Birth through Midlife in 2 British Birth Cohorts

Importance: Atopic eczema is characterized by a heterogenous waxing and waning course, with variable age of onset and persistence of symptoms. Distinct patterns of disease activity such as early-onset/resolving and persistent disease have been identified throughout childhood; little is known about patterns into adulthood. Objective: This study aimed to identify subtypes of atopic eczema based on patterns of disease activity through mid-adulthood, to examine whether early life risk factors and participant characteristics are associated with these subtypes, and to determine whether subtypes are associated with other atopic diseases and general health in mid-adulthood. Design, Setting, and Participants: This study evaluated members of 2 population-based birth cohorts, the 1958 National Childhood Development Study (NCDS) and the 1970 British Cohort Study (BCS70). Participant data were collected over the period between 1958 and 2016. Data were analyzed over the period between 2018 and 2020. Main Outcomes and Measures: Subtypes of atopic eczema were identified based on self-reported atopic eczema period prevalence at multiple occasions. These subtypes were the outcome in models of early life characteristics and an exposure variable in models of midlife health. Results: Latent class analysis identified 4 subtypes of atopic eczema with distinct patterns of disease activity among 15939 individuals from the NCDS (51.4% male, 75.4% White) and 14966 individuals from the BCS70 (51.6% male, 78.8% White): rare/no (88% to 91%), decreasing (4%), increasing (2% to 6%), and persistently high (2% to 3%) probability of reporting prevalent atopic eczema with age. Sex at birth and early life factors, including social class, region of residence, tobacco smoke exposure, and breastfeeding, predicted differences between the 3 atopic eczema subtypes and the infrequent/no atopic eczema group, but only female sex differentiated the high and decreasing probability subtypes (odds ratio [OR], 1.99; 95% CI, 1.66-2.38). Individuals in the high subtype were most likely to experience asthma and rhinitis, and those in the increasing subtype were at higher risk of poor self-reported general (OR, 1.29; 95% CI, 1.09-1.53) and mental (OR 1.45; 95% CI, 1.23-1.72) health in midlife. Conclusions and Relevance: The findings of this cohort study suggest that extending the window of observation beyond childhood may reveal clear subtypes of atopic eczema based on patterns of disease activity. A newly identified subtype with increasing probability of activity in adulthood warrants additional attention given observed associations with poor self-reported health in midlife.

Common mental health disorders in adults with inflammatory skin conditions: nationwide population-based matched cohort studies in the UK

BACKGROUND: Psoriasis and atopic eczema are common inflammatory skin diseases. Existing research has identified increased risks of common mental disorders (anxiety, depression) in people with eczema and psoriasis; however, explanations for the associations remain unclear. We aimed to establish the risk factors for mental illness in those with eczema or psoriasis and identify the population groups most at risk. METHODS: We used routinely collected data from the UK Clinical Practice Research Datalink (CPRD) GOLD. Adults registered with a general practice in CPRD (1997-2019) were eligible for inclusion. Individuals with eczema/psoriasis were matched (age, sex, practice) to up to five adults without eczema/psoriasis. We used Cox regression to estimate hazard ratios (HRs) and 95% confidence intervals (CIs) for hazards of anxiety or depression in people with eczema/psoriasis compared to people without. We adjusted for known confounders (deprivation, asthma [eczema], psoriatic arthritis [psoriasis], Charlson comorbidity index, calendar period) and potential mediators (harmful alcohol use, body mass index [BMI], smoking status, and, in eczema only, sleep quality [insomnia diagnoses, specific sleep problem medications] and high-dose oral glucocorticoids). RESULTS: We identified two cohorts with and without eczema (1,032,782, matched to 4,990,125 without), and with and without psoriasis (366,884, matched to 1,834,330 without). Sleep quality was imbalanced in the eczema cohorts, twice as many people with eczema had evidence of poor sleep at baseline than those without eczema, including over 20% of those with severe eczema. After adjusting for potential confounders and mediators, eczema and psoriasis were associated with anxiety (adjusted HR [95% CI]: eczema 1.14 [1.13-1.16], psoriasis 1.17 [1.15-1.19]) and depression (adjusted HR [95% CI]: eczema 1.11 [1.1-1.12], psoriasis 1.21 [1.19-1.22]). However, we found evidence that these increased hazards are unlikely to be constant over time and were especially high 1-year after study entry. CONCLUSIONS: Atopic eczema and psoriasis are associated with increased incidence of anxiety and depression in adults. These associations may be mediated through known modifiable risk factors, especially sleep quality in people with eczema. Our findings highlight potential opportunities for the prevention of anxiety and depression in people with eczema/psoriasis through treatment of modifiable risk factors and enhanced eczema/psoriasis management

Major depression and survival in people with cancer

OBJECTIVE: The question of whether depression is associated with worse survival in people with cancer remains unanswered because of methodological criticism of the published research on the topic. We aimed to study the association in a large methodologically robust study. METHODS: We analysed data on 20,582 patients with breast, colorectal, gynaecological, lung and prostate cancers who had attended cancer outpatient clinics in Scotland, UK. Patients had completed two-stage screening for major depression as part of their cancer care. These data on depression status were linked to demographic, cancer and subsequent mortality data from national databases. We estimated the association of major depression with survival for each cancer using Cox regression. We adjusted for potential confounders and interactions between potentially time-varying confounders and the interval between cancer diagnosis and depression screening, and used multiple imputation for missing depression and confounder data. We pooled the cancer-specific results using fixed-effects meta-analysis. RESULTS: Major depression was associated with worse survival for all cancers, with similar adjusted hazard ratios: breast cancer (HR 1.42, 95% CI 1.15-1.75), colorectal cancer (HR 1.47, 95% CI 1.11-1.94), gynaecological cancer (HR 1.36, 95% CI 1.08-1.71), lung cancer (HR 1.39, 95% CI 1.24-1.56), prostate cancer (HR 1.76, 95% CI 1.08-2.85). The pooled hazard ratio was 1.41 (95% CI 1.29-1.54, p<0.001, I2=0%). These findings were not materially different when we only considered the deaths (90%) that were attributed to cancer. CONCLUSIONS: Major depression is associated with worse survival in patients with common cancers. The mechanisms of this association and the clinical implications require further study

Unbiased and automated identification of a circulating tumour cell definition that associates with overall survival

Circulating tumour cells (CTC) in patients with metastatic carcinomas are associated with poor survival and can be used to guide therapy. Classification of CTC however remains subjective, as they are morphologically heterogeneous. We acquired digital images, using the CellSearch™ system, from blood of 185 castration resistant prostate cancer (CRPC) patients and 68 healthy subjects to define CTC by computer algorithms. Patient survival data was used as the training parameter for the computer to define CTC. The computer-generated CTC definition was validated on a separate CRPC dataset comprising 100 patients. The optimal definition of the computer defined CTC (aCTC) was stricter as compared to the manual CellSearch CTC (mCTC) definition and as a consequence aCTC were less frequent. The computer-generated CTC definition resulted in hazard ratios (HRs) of 2.8 for baseline and 3.9 for follow-up samples, which is comparable to the mCTC definition (baseline HR 2.9, follow-up HR 4.5). Validation resulted in HRs at baseline/follow-up of 3.9/5.4 for computer and 4.8/5.8 for manual definitions. In conclusion, we have defined and validated CTC by clinical outcome using a perfectly reproducing automated algorithm

Inflammatory skin diseases and the risk of chronic kidney disease: population-based case-control and cohort analyses.

BACKGROUND: Emerging evidence suggests an association between common inflammatory skin diseases and chronic kidney disease (CKD). OBJECTIVES: To explore the association between CKD stages 3-5 (CKD3-5) and atopic eczema, psoriasis, rosacea and hidradenitis suppurativa. METHODS: We undertook two complementary analyses; a prevalent case-control study and a cohort study using routinely collected primary care data [UK Clinical Practice Research Datalink (CPRD)]. We matched individuals with CKD3-5 in CPRD in March 2018 with up to five individuals without CKD for general practitioner practice, age and sex. We compared the prevalence of CKD3-5 among individuals with and without each inflammatory skin disease. We included individuals in CPRD with diabetes mellitus (2004-2018) in a cohort analysis to compare the incidence of CKD3-5 among people with and without atopic eczema and psoriasis. RESULTS: Our study included 56 602 cases with CKD3-5 and 268 305 controls. Cases were more likely than controls to have a history of atopic eczema [odds ratio (OR) 1·14, 99% confidence interval (CI) 1·11-1·17], psoriasis (OR 1·13, 99% CI 1·08-1·19) or hidradenitis suppurativa (OR 1·49, 99% CI 1·19-1·85), but were slightly less likely to have been diagnosed with rosacea (OR 0·92, 99% CI 0·87-0·97), after adjusting for age, sex, practice (matching factors), index of multiple deprivation, diabetes, smoking, harmful alcohol use and obesity. Results remained similar after adjusting for hypertension and cardiovascular disease. In the cohort with diabetes (N = 335 827), there was no evidence that CKD3-5 incidence was associated with atopic eczema or psoriasis. CONCLUSIONS: Atopic eczema, psoriasis and hidradenitis suppurativa are weakly associated with CKD3-5. Future research is needed to elucidate potential mechanisms and the clinical significance of our findings

Severe Mental Illness Among Adults with Atopic Eczema or Psoriasis: Population-Based Matched Cohort Studies within UK Primary Care

BACKGROUND: Existing research exploring associations between atopic eczema (AE) or psoriasis, and severe mental illness (SMI – ie, schizophrenia, bipolar disorder, other psychoses) is limited, with longitudinal evidence particularly scarce. Therefore, temporal directions of associations are unclear. We aimed to investigate associations between AE or psoriasis and incident SMI among adults. METHODS: We conducted matched cohort studies using primary care electronic health records (January 1997 to January 2020) from the UK Clinical Practice Research Datalink GOLD. We identified two cohorts: 1) adults (≥ 18 years) with and without AE and 2) adults with and without psoriasis. We matched (on age, sex, general practice) adults with AE or psoriasis with up to five adults without. We used Cox regression, stratified by matched set, to estimate hazard ratios (HRs) comparing incident SMI among adults with and without AE or psoriasis. RESULTS: We identified 1,023,232 adults with AE and 4,908,059 without, and 363,210 with psoriasis and 1,801,875 without. After adjusting for matching variables (age, sex, general practice) and potential confounders (deprivation, calendar period) both AE and psoriasis were associated with at least a 17% increased hazard of SMI (AE: HR=1.17,95% CI=1.12– 1.22; psoriasis: HR=1.26,95% CI=1.18– 1.35). After additionally adjusting for potential mediators (comorbidity burden, harmful alcohol use, smoking status, body mass index, and, in AE only, sleep problems and high-dose glucocorticoids), associations with SMI did not persist for AE (HR=0.98,95% CI=0.93– 1.04), and were attenuated for psoriasis (HR=1.14,95% CI=1.05– 1.23). CONCLUSION: Our findings suggest adults with AE or psoriasis are at increased risk of SMI compared to matched comparators. After adjusting for potential mediators, associations with SMI did not persist for AE, and were attenuated for psoriasis, suggesting that the increased risk may be explained by mediating factors (eg, sleep problems). Our research highlights the importance of monitoring mental health in adults with AE or psoriasis
