RESUMEN

Objective: Child survival after intensive care unit (ICU) hospitalization has increased, yet many children experience acute stress that may precipitate mental/behavioral health comorbidities. Parents report stress after their child's hospitalization. Little is known about the individual and family characteristics that may moderate intergenerational relationships of acute stress. Design: Following ICU admission at a large academic medical center, a prospective cross-sectional cohort study assessed the associations between intergenerational characteristics and acute stress among children and families. Patients: Parent-child dyads (N = 88) were recruited from the pediatric ICU and pediatric cardiovascular ICU (CVICU) following ICU discharge. Eligible children were between 8 and 18 years old with ICU stays longer than 24 hours. Children with developmental delays were excluded. Caregivers were proficient in English or Spanish. Surveys were collected before hospital discharge. Measurements/Main Results: The primary outcome was "child stress" defined as a score≥17, measured by the Children's Revised Impact of Events Scale (CRIES-8). "Parent stress" was defined as an elevated composite score on the Stanford Acute Stress Reaction Questionnaire. We used validated scales to assess the child's clinical and family social characteristics. Acute stress was identified in 34 (39.8%) children and 50 (56.8%) parents. In multivariate linear regression analyses adjusting for social characteristics, parent stress was associated with increased risk of child stress (adjusted odds ratio 2.58, 95% confidence interval 0.69, 4.46, p < .01). In unadjusted analyses, Hispanic ethnicity was associated with greater child stress. In adjusted analyses, race, income, ICU length of stay, and language were not associated with child stress and did not moderate the parent-child stress relationship. Conclusions: Parent stress is closely correlated with child stress during ICU hospitalization. Hispanic ethnicity may be associated with increased risk for child stress, but further studies are required to define the roles of other social and clinical measures.

RESUMEN

BACKGROUND: Home working has increased since the Coronavirus Disease 2019 (COVID-19) pandemic's onset with concerns that it may have adverse health implications. We assessed the association between home working and social and mental wellbeing among the employed population aged 16 to 66 through harmonised analyses of 7 UK longitudinal studies. METHODS AND FINDINGS: We estimated associations between home working and measures of psychological distress, low life satisfaction, poor self-rated health, low social contact, and loneliness across 3 different stages of the pandemic (T1 = April to June 2020 -first lockdown, T2 = July to October 2020 -eased restrictions, T3 = November 2020 to March 2021 -second lockdown) using modified Poisson regression and meta-analyses to pool results across studies. We successively adjusted the model for sociodemographic characteristics (e.g., age, sex), job characteristics (e.g., sector of activity, pre-pandemic home working propensities), and pre-pandemic health. Among respectively 10,367, 11,585, and 12,179 participants at T1, T2, and T3, we found higher rates of home working at T1 and T3 compared with T2, reflecting lockdown periods. Home working was not associated with psychological distress at T1 (RR = 0.92, 95% CI = 0.79 to 1.08) or T2 (RR = 0.99, 95% CI = 0.88 to 1.11), but a detrimental association was found with psychological distress at T3 (RR = 1.17, 95% CI = 1.05 to 1.30). Study limitations include the fact that pre-pandemic home working propensities were derived from external sources, no information was collected on home working dosage and possible reverse association between change in wellbeing and home working likelihood. CONCLUSIONS: No clear evidence of an association between home working and mental wellbeing was found, apart from greater risk of psychological distress during the second lockdown, but differences across subgroups (e.g., by sex or level of education) may exist. Longer term shifts to home working might not have adverse impacts on population wellbeing in the absence of pandemic restrictions but further monitoring of health inequalities is required.

RESUMEN

A regression-based fusion algorithm has been used to merge hyperspectral Fourier transform infrared (FTIR) data with an H&E image of oral squamous cell carcinoma metastases in cervical lymphoid nodal tissue. This provides insight into the success of the ratio of FTIR absorbances at 1252 cm-1 and 1285 cm-1 in discriminating between these tissue types. The success is due to absorbances at these two wavenumbers being dominated by contributions from DNA and collagen, respectively. A pixel-by-pixel fit of the fused spectra to the FTIR spectra of collagen, DNA and cytokeratin reveals the contributions of these molecules to the tissue at high spatial resolution.

RESUMEN

A machine learning algorithm (MLA) has predicted the prognosis of oral potentially malignant lesions and discriminated between lymph node tissue and metastatic oral squamous cell carcinoma (OSCC). The MLA analyses metrics, which are ratios of Fourier transform infrared absorbances, and identifies key wavenumbers that can be associated with molecular biomarkers. The wider efficacy of the MLA is now shown in the more complex primary OSCC tumour setting, where it is able to identify seven types of tissue. Three epithelial and four non-epithelial tissue types were discriminated from each other with sensitivities between 82% and 96% and specificities between 90% and 99%. The wavenumbers involved in the five best discriminating metrics for each tissue type were tightly grouped, indicating that small changes in the spectral profiles of the different tissue types are important. The number of samples used in this study was small, but the information will provide a basis for further, larger investigations.

RESUMEN

Multiple studies across global populations have established the primary symptoms characterising Coronavirus Disease 2019 (COVID-19) and long COVID. However, as symptoms may also occur in the absence of COVID-19, a lack of appropriate controls has often meant that specificity of symptoms to acute COVID-19 or long COVID, and the extent and length of time for which they are elevated after COVID-19, could not be examined. We analysed individual symptom prevalences and characterised patterns of COVID-19 and long COVID symptoms across nine UK longitudinal studies, totalling over 42,000 participants. Conducting latent class analyses separately in three groups ('no COVID-19', 'COVID-19 in last 12 weeks', 'COVID-19 > 12 weeks ago'), the data did not support the presence of more than two distinct symptom patterns, representing high and low symptom burden, in each group. Comparing the high symptom burden classes between the 'COVID-19 in last 12 weeks' and 'no COVID-19' groups we identified symptoms characteristic of acute COVID-19, including loss of taste and smell, fatigue, cough, shortness of breath and muscle pains or aches. Comparing the high symptom burden classes between the 'COVID-19 > 12 weeks ago' and 'no COVID-19' groups we identified symptoms characteristic of long COVID, including fatigue, shortness of breath, muscle pain or aches, difficulty concentrating and chest tightness. The identified symptom patterns among individuals with COVID-19 > 12 weeks ago were strongly associated with self-reported length of time unable to function as normal due to COVID-19 symptoms, suggesting that the symptom pattern identified corresponds to long COVID. Building the evidence base regarding typical long COVID symptoms will improve diagnosis of this condition and the ability to elicit underlying biological mechanisms, leading to better patient access to treatment and services.

RESUMEN

Caregiving relationships in the postnatal period are critical to an infant's development. Preterm infants and their parents face unique challenges in this regard, with infants experiencing separation from parents, uncomfortable procedures, and increased biologic vulnerability, and parents facing difficulties assuming caregiver roles and increased risk for psychological distress. To better understand the NICU parent-infant relationship, we conducted a review of the literature and identified 52 studies comparing observed maternal, infant, and dyadic interaction behavior in preterm dyads with full-term dyads. Eighteen of 40 studies on maternal behavior found less favorable behavior, including decreased sensitivity and more intrusiveness in mothers of preterm infants, seven studies found the opposite, four studies found mixed results, and 11 studies found no differences. Seventeen of 25 studies on infant behavior found less responsiveness in preterm infants, two studies found the opposite, and the remainder found no difference. Eighteen out of 14 studies on dyad-specific behavior reported less synchrony in preterm dyads and the remainder found no differences. We identify confounding factors that may explain variations in results, present an approach to interpret existing data by framing differences in maternal behavior as potentially adaptive in the context of prematurity, and suggest future areas for exploration.


Las relaciones de prestación de cuidados en el período postnatal son críticas para el desarrollo del infante. Los infantes nacidos prematuramente y sus progenitores enfrentan retos únicos a este respecto, con los infantes que experimentan la separación de sus progenitores, procedimientos incómodos, así como un aumento en la vulnerabilidad biológica; y los progenitores enfrentando dificultades al asumir el papel de cuidadores y el aumento de riesgo de angustia sicológica. Para comprender mejor la relación progenitor-infante en la Unidad Neonatal de Cuidados Intensivos (NICU), llevamos a cabo una revisión de la literatura e identificamos 52 estudios que comparan la observada conducta de interacción materna, del infante y de la díada en díadas de infantes prematuros con díadas de infantes de gestación completa. Dieciocho de 40 estudios sobre la conducta materna encontraron una menos favorable conducta, incluyendo una baja en la sensibilidad y más intrusión en el caso de madres de infantes prematuros; 7 estudios encontraron que se daba la situación opuesta; 4 estudios presentaron resultados mixtos; y 11 estudios no encontraron diferencias. Diecisiete de 25 estudios sobre el comportamiento del infante encontraron una menor capacidad de respuesta en infantes prematuros; dos estudios encontraron que se daba la situación opuesta; y el resto de los estudios no encontró ninguna diferencia. Ocho de 14 estudios sobre el comportamiento específico de la díada reportaron menos sincronía en las díadas con infantes prematuros y el resto de los estudios no encontró ninguna diferencia. Identificamos factores confusos que pudieran explicar las variaciones en los resultados, presentamos un acercamiento para interpretar la información existente por medio de enmarcar las diferencias en la conducta materna como potencialmente adaptable en el contexto del nacimiento prematuro, y sugerimos futuras áreas para ser exploradas.


Les relations de soin dans la période postnatale sont critiques pour le développement du nourrisson. Les bébés nés avant terme et leurs parents font face à des défis uniques à cet égard, avec les bébés faisant l'expérience de la séparation des parents, des procédures désagréables et difficiles, et une vulnérabilité biologique accrue, et les parents faisant face aux difficultés assumant des rôles de soignants et étant à risque plus élevé de détresse psychologique. Afin de comprendre la relation parent-nourrisson USIN nous avons passé en revue toutes les recherches et identifié 52 études comparant le comportement d'interaction dyadique, maternel et du nourrisson chez des dyades prématurées avec des dyades à plein terme. 18 des 40 études sur le comportement maternel ont trouvé un comportement moins que favorable, y compris une sensibilité décrue et plus d'intrusion chez les mères de nourrissons prématurés, 7 études ont trouvé le contraire, 4 études ont trouvé des résultats mélangés, et 11 études n'ont trouvé aucune différence. 17 études sur 25 sur le comportement du nourrisson ont trouvé une réaction moindre chez les nourrissons prématurés deux études ont trouvé le contraire, et le reste n'a trouvé aucune différence. 8 études sur 14 sur le comportement spécifique à la dyade ont fait état de moins de synchronie chez les dyades avant terme et les autres études n'ont trouvé aucune différence. Nous identifions des facteurs confondants qui pourraient expliquer des variations dans les résultats et nous présentons une approche pour interpréter les données existantes en cadrant des différences dans le comportement maternel comme étant potentiellement adaptatives dans le contexte de la prématurité et nous suggérons des domaines futurs d'exploration.

RESUMEN

Linked administrative data offer a rich source of information that can be harnessed to describe patterns of disease, understand their causes and evaluate interventions. However, administrative data are primarily collected for operational reasons such as recording vital events for legal purposes, and planning, provision and monitoring of services. The processes involved in generating and linking administrative datasets may generate sources of bias that are often not adequately considered by researchers. We provide a framework describing these biases, drawing on our experiences of using the 100 Million Brazilian Cohort (100MCohort) which contains records of more than 131 million people whose families applied for social assistance between 2001 and 2018. Datasets for epidemiological research were derived by linking the 100MCohort to health-related databases such as the Mortality Information System and the Hospital Information System. Using the framework, we demonstrate how selection and misclassification biases may be introduced in three different stages: registering and recording of people's life events and use of services, linkage across administrative databases, and cleaning and coding of variables from derived datasets. Finally, we suggest eight recommendations which may reduce biases when analysing data from administrative sources.

RESUMEN

BACKGROUND: Recent work suggests that antihypertensive medications may be useful as repurposed treatments for mood disorders. Using large-scale linked healthcare data we investigated whether certain classes of antihypertensive, such as angiotensin antagonists (AAs) and calcium channel blockers, were associated with reduced risk of new-onset major depressive disorder (MDD) or bipolar disorder (BD). METHOD: Two cohorts of patients treated with antihypertensives were identified from Scottish prescribing (2009-2016) and hospital admission (1981-2016) records. Eligibility for cohort membership was determined by a receipt of a minimum of four prescriptions for antihypertensives within a 12-month window. One treatment cohort (n = 538 730) included patients with no previous history of mood disorder, whereas the other (n = 262 278) included those who did. Both cohorts were matched by age, sex and area deprivation to untreated comparators. Associations between antihypertensive treatment and new-onset MDD or bipolar episodes were investigated using Cox regression. RESULTS: For patients without a history of mood disorder, antihypertensives were associated with increased risk of new-onset MDD. For AA monotherapy, the hazard ratio (HR) for new-onset MDD was 1.17 (95% CI 1.04-1.31). Beta blockers' association was stronger (HR 2.68; 95% CI 2.45-2.92), possibly indicating pre-existing anxiety. Some classes of antihypertensive were associated with protection against BD, particularly AAs (HR 0.46; 95% CI 0.30-0.70). For patients with a past history of mood disorders, all classes of antihypertensives were associated with increased risk of future episodes of MDD. CONCLUSIONS: There was no evidence that antihypertensive medications prevented new episodes of MDD but AAs may represent a novel treatment avenue for BD.

RESUMEN

OBJECTIVE: Atherosclerosis is the underlying cause of most cardiovascular disease, but mechanisms underlying atherosclerosis are incompletely understood. Ultrasound measurement of the carotid intima-media thickness (cIMT) can be used to measure vascular remodeling, which is indicative of atherosclerosis. Genome-wide association studies have identified many genetic loci associated with cIMT, but heterogeneity of measurements collected by many small cohorts have been a major limitation in these efforts. Here, we conducted genome-wide association analyses in UKB (UK Biobank; N=22 179), the largest single study with consistent cIMT measurements. Approach and Results: We used BOLT-LMM software to run linear regression of cIMT in UKB, adjusted for age, sex, and genotyping chip. In white British participants, we identified 5 novel loci associated with cIMT and replicated most previously reported loci. In the first sex-specific analyses of cIMT, we identified a locus on chromosome 5, associated with cIMT in women only and highlight VCAN as a good candidate gene at this locus. Genetic correlations with body mass index and glucometabolic traits were also observed. Two loci influenced risk of ischemic heart disease. CONCLUSIONS: These findings replicate previously reported associations, highlight novel biology, and provide new directions for investigating the sex differences observed in cardiovascular disease presentation and progression.

RESUMEN

A novel machine learning algorithm is shown to accurately discriminate between oral squamous cell carcinoma (OSCC) nodal metastases and surrounding lymphoid tissue on the basis of a single metric, the ratio of Fourier transform infrared (FTIR) absorption intensities at 1252 cm-1 and 1285 cm-1. The metric yields discriminating sensitivities, specificities and precision of 98.8 ± 0.1%, 99.89 ± 0.01% and 99.78 ± 0.02% respectively, and an area under receiver operator characteristic (AUC) of 0.9935 ± 0.0006. The delineation of the OSCC and lymphoid tissue revealed by the image formed from the metric is in better agreement with an immunohistochemistry (IHC) stained image than are either of the FTIR images obtained at the individual wavenumbers. Scanning near-field optical microscopy (SNOM) images of the tissue obtained at a number of key wavenumbers, with high spatial resolution, show variations in the chemical structure of the tissue with a feature size down to ∼4 µm. The image formed from the ratio of the SNOM images obtained at 1252 cm-1 and 1285 cm-1 shows more contrast than the SNOM images obtained at these or a number of other individual wavenumbers. The discrimination between the two tissue types is dominated by the contribution from the 1252 cm-1 signal, which is representative of nucleic acids, and this shows the OSCC tissue to be accompanied by two wide arcs of tissue which are particularly low in nucleic acids. Haematoxylin and eosin (H&E) staining shows the tumour core in this specimen to be ∼40 µm wide and the SNOM topography shows that the core centre is raised by ∼1 µm compared to the surrounding tissue. Line profiles of the SNOM signal intensity taken through the highly keratinised core show that the increase in height correlates with an increase in the protein signal. SNOM line profiles show that the nucleic acids signal decreases at the centre of the tumour core between two peaks of higher intensity. All these nucleic acid features are ∼25 µm wide, roughly the width of two cancer cells.

RESUMEN

PURPOSE: The patient concerns inventory (PCI) is a prompt list allowing head and neck cancer (HNC) patients to discuss issues that otherwise might be overlooked. This trial evaluated the effectiveness of using the PCI at routine outpatient clinics for one year after treatment on health-related QOL (HRQOL). METHODS: A pragmatic cluster preference randomised control trial with 15 consultants, 8 'using' and 7 'not using' the PCI intervention. Patients treated with curative intent (all sites, disease stages, treatments) were eligible. RESULTS: Consultants saw a median (inter-quartile range) 16 (13-26) patients, with 140 PCI and 148 control patients. Of the pre-specified outcomes, the 12-month results for the mean University of Washington Quality of Life (UW-QOLv4) social-emotional subscale score suggested a small clinical effect of intervention of 4.6 units (95% CI 0.2, 9.0), p = 0.04 after full adjustment for pre-stated case-mix. Results for UW-QOLv4 overall quality of life being less than good at 12 months (primary outcome) also favoured the PCI with a risk ratio of 0.83 (95% CI 0.66, 1.06) and absolute risk 4.8% (- 2.9%, 12.9%) but without achieving statistical significance. Other non-a-priori analyses, including all 12 UWQOL domains and at consultant level also suggested better HRQOL with PCI. Consultation times were unaffected and the number of items selected decreased over time. CONCLUSION: This novel trial supports the integration of the PCI approach into routine consultations as a simple low-cost means of benefiting HNC patients. It adds to a growing body of evidence supporting the use of patient prompt lists more generally.

RESUMEN

Identifying large expansions of short tandem repeats (STRs), such as those that cause amyotrophic lateral sclerosis (ALS) and fragile X syndrome, is challenging for short-read whole-genome sequencing (WGS) data. A solution to this problem is an important step toward integrating WGS into precision medicine. We developed a software tool called ExpansionHunter that, using PCR-free WGS short-read data, can genotype repeats at the locus of interest, even if the expanded repeat is larger than the read length. We applied our algorithm to WGS data from 3001 ALS patients who have been tested for the presence of the C9orf72 repeat expansion with repeat-primed PCR (RP-PCR). Compared against this truth data, ExpansionHunter correctly classified all (212/212, 95% CI [0.98, 1.00]) of the expanded samples as either expansions (208) or potential expansions (4). Additionally, 99.9% (2786/2789, 95% CI [0.997, 1.00]) of the wild-type samples were correctly classified as wild type by this method with the remaining three samples identified as possible expansions. We further applied our algorithm to a set of 152 samples in which every sample had one of eight different pathogenic repeat expansions, including those associated with fragile X syndrome, Friedreich's ataxia, and Huntington's disease, and correctly flagged all but one of the known repeat expansions. Thus, ExpansionHunter can be used to accurately detect known pathogenic repeat expansions and provides researchers with a tool that can be used to identify new pathogenic repeat expansions.

RESUMEN

iRhom2 is an inactive rhomboid protease involved in diverse signalling events. It has been implicated in the pathogenesis of a number of cancer types, including oesophageal and ovarian cancer, while its closely associated family member, iRhom1, is implicated in head and neck cancer. However, a role for iRhom2 in head and neck cancer has not been investigated. Immunoblotting for iRhom2 in 54 oral squamous cell carcinoma (OSCC) and 24 paired normal tissues demonstrated higher levels of iRhom2 protein in tumour compared with normal samples (P < 0.05). iRhom2 over-expression correlated with poor patient survival (P < 0.0005) but with no other clinicopathological variable. Increased cell migration was observed in stably over-expressing iRhom2 clones of OSCC cell lines in the absence of increased cell proliferation, but not in the normal oral keratinocyte cell line, NOK-hTERT, and this was abrogated by knock-down of iRhom2. iRhom2 protein expression is increased in a proportion of OSCC and this up-regulation is associated with faster cell migration and decreased patient survival. These data implicate iRhom2-controlled signalling events in the pathogenesis of this cancer.

RESUMEN

BACKGROUND: Placement of an implantable cardioverter defibrillator (ICD) is often accompanied by psychological adjustment issues in pediatric patients and their parents. Although anxiety, depression, and lowered quality of life have been seen in these patients, no studies have investigated patient or parent reported needs. This exploratory study describes the needs of pediatric ICD patients and parents and assesses whether patient factors of age, gender, depression, and anxiety are associated with specific needs. METHODS: ICD patients ages 8-21 years and their parents completed a needs analysis survey assessing various domains of functioning. Patients also completed self-reported measures of depression and anxiety. RESULTS: Thirty-two patients (28% female) and their parents (72% mothers) completed the survey. Patients' most frequently endorsed needs involved educational issues: understanding their cardiac event/diagnosis (34%), medications (34%), and how the ICD would change their lifestyle (31%). Parents' most frequently endorsed needs involved family issues; almost half of parents (47%) were concerned about their children's frustration with their overprotectiveness and 28% were concerned with their child feeling depressed or anxious. Patients who reported feeling overprotected (12.1 ± 3.4 vs 17.4 ± 3.5 years; P = .001) were significantly younger than those who did not. Experiencing peer issues was more frequently endorsed by females than males (33% of females vs 4% of males; P = .026). CONCLUSIONS: ICD patients and parents endorsed markedly different needs. Patients focused on understanding their ICD, whereas parents were more focused on their children's emotional needs. Novel ways of educating patients about their device and clinic-based screenings of emotional functioning may serve to meet these needs.

RESUMEN

The novel coronavirus disease 2019 (COVID-19) pandemic is affecting care for high-risk newborns in ways that will likely be sustained beyond the initial pandemic response. These novel challenges present an urgent imperative to understand how COVID-19 impacts parent, family, and infant outcomes. We highlight three areas that warrant targeted attention: (1) inpatient care: visitation policies, developmental care, and communication practices; (2) outpatient care: high-risk infant follow-up and early intervention programs; and (3) parent psychosocial distress: mental health, social support, and financial toxicity. Changes to care delivery in these areas provide an opportunity to identify and implement novel strategies to provide family-centered care during COVID-19 and beyond. KEY POINTS: · The COVID-19 pandemic is influencing care delivery for high-risk newborns and their families.. · Rapid changes to care delivery are likely to be sustained beyond the initial pandemic response.. · We have an urgent imperative to understand how COVID-19 impacts infant, parent, and family outcomes..

RESUMEN

PURPOSE: The main aim of this paper is to present baseline demographic and clinical characteristics and HRQOL in the two groups of the Patient Concerns Inventory (PCI) trial. The baseline PCI data will also be described. METHODS: This is a pragmatic cluster preference randomised control trial with 15 consultant clusters from two sites either 'using' (n = 8) or 'not using' (n = 7) the PCI at a clinic for all of their trial patients. The PCI is a 56-item prompt list that helps patients raise concerns that otherwise might be missed. Eligibility was head and neck cancer patients treated with curative intent (all sites, stage of disease, treatments). RESULTS: From 511 patients first identified as eligible when screening for the multi-disciplinary tumour board meetings, 288 attended a first routine outpatient baseline study clinic after completion of their treatment, median (IQR) of 103 (71-162) days. At baseline, the two trial groups were similar in demographic and clinical characteristics as well as in HRQOL measures apart from differences in tumour location, tumour staging and mode of treatment. These exceptions were cluster (consultant) related to Maxillofacial and ENT consultants seeing different types of cases. Consultation times were similar, with PCI group times taking about 1 min longer on average (95% CL for the difference between means was from - 0.7 to + 2.2 min). CONCLUSION: Using the PCI in routine post-treatment head and neck cancer clinics do not elongate consultations. Recruitment has finished but 12-month follow-up is still ongoing.

RESUMEN

BACKGROUND: Guidelines remain unclear over whether patients with early stage oral cancer without overt neck disease benefit from upfront elective neck dissection (END), particularly those with the smallest tumours. METHODS: We conducted a randomised trial of patients with stage T1/T2 N0 disease, who had their mouth tumour resected either with or without END. Data were also collected from a concurrent cohort of patients who had their preferred surgery. Endpoints included overall survival (OS) and disease-free survival (DFS). We conducted a meta-analysis of all six randomised trials. RESULTS: Two hundred fifty randomised and 346 observational cohort patients were studied (27 hospitals). Occult neck disease was found in 19.1% (T1) and 34.7% (T2) patients respectively. Five-year intention-to-treat hazard ratios (HR) were: OS HR = 0.71 (p = 0.18), and DFS HR = 0.66 (p = 0.04). Corresponding per-protocol results were: OS HR = 0.59 (p = 0.054), and DFS HR = 0.56 (p = 0.007). END was effective for small tumours. END patients experienced more facial/neck nerve damage; QoL was largely unaffected. The observational cohort supported the randomised findings. The meta-analysis produced HR OS 0.64 and DFS 0.54 (p < 0.001). CONCLUSION: SEND and the cumulative evidence show that within a generalisable setting oral cancer patients who have an upfront END have a lower risk of death/recurrence, even with small tumours.

RESUMEN

BACKGROUND: Learners developing competency-based skills, attitudes, and knowledge through the achievement of defined milestones is a core feature of competency-based medical education. In 2017, a special interest study group of the American Academy of Child and Adolescent Psychiatry convened a panel of specialists to describe pediatric consultation-liaison psychiatry (CLP) best educational practices during child and adolescent psychiatry fellowship. OBJECTIVE: The objective of this project was to develop a national consensus on pediatric CLP competencies to help guide training in this specialty. METHODS: An expert working group developed a list of candidate competences based on previously established educational outcomes for CLP (formerly Psychosomatic Medicine), child and adolescent psychiatry, and general psychiatry. A survey was distributed to members of the American Academy of Child and Adolescent Psychiatry Physically Ill Child Committee to determine child and adolescent psychiatry fellowship educational needs on pediatric CLP services and generate consensus regarding pediatric CLP competencies. RESULTS: Most survey respondents were supportive of the need for a national consensus on core competencies for pediatric CLP. Consensus from a panel of experts in the field of pediatric CLP generated a list of proposed core competencies that track the Accreditation Council for Graduate Medical Education's six core competencies. CONCLUSIONS: Consistent learning outcomes provide the foundation for further development of tools to support training in pediatric CLP. There is a need to develop further tools including outcome assessment instruments and self-directed learning materials that can be used to support lifelong learning.

RESUMEN

BACKGROUND: Sedentary behaviour is related to poorer health independently of time spent in moderate to vigorous physical activity. The aim of this study was to investigate whether wellbeing or symptoms of anxiety or depression predict sedentary behaviour in older adults. METHOD: Participants were drawn from the Lothian Birth Cohort 1936 (LBC1936) (n = 271), and the West of Scotland Twenty-07 1950s (n = 309) and 1930s (n = 118) cohorts. Sedentary outcomes, sedentary time, and number of sit-to-stand transitions, were measured with a three-dimensional accelerometer (activPAL activity monitor) worn for 7 days. In the Twenty-07 cohorts, symptoms of anxiety and depression were assessed in 2008 and sedentary outcomes were assessed ~ 8 years later in 2015 and 2016. In the LBC1936 cohort, wellbeing and symptoms of anxiety and depression were assessed concurrently with sedentary behaviour in 2015 and 2016. We tested for an association between wellbeing, anxiety or depression and the sedentary outcomes using multivariate regression analysis. RESULTS: We observed no association between wellbeing or symptoms of anxiety and the sedentary outcomes. Symptoms of depression were positively associated with sedentary time in the LBC1936 and Twenty-07 1950s cohort, and negatively associated with number of sit-to-stand transitions in the LBC1936. Meta-analytic estimates of the association between depressive symptoms and sedentary time or number of sit-to-stand transitions, adjusted for age, sex, BMI, long-standing illness, and education, were ß = 0.11 (95% CI = 0.03, 0.18) and ß = - 0.11 (95% CI = - 0.19, -0.03) respectively. CONCLUSION: Our findings indicate that depressive symptoms are positively associated with sedentary behavior. Future studies should investigate the causal direction of this association.
