Development of Functional Symptoms in Children Exposed to Traumatic Events

This chapter will review the typical symptoms occurring in children after stressful traumatic exposures. Unlike other chapters in this book, no specific organ system is the most likely focus of functional symptoms in this setting. Psychological distress may exacerbate symptoms of physical illness and injury associated with the traumatic events, may be expressed as almost any seemingly unrelated symptom, may intensify the age appropriate fears typical of any child, or may predominantly be exhibited behaviorally. In most nonsevere cases, the impact is self-limited and the individual’s functioning will be back to normal within days or weeks. We will suggest simple behavioral and environmental interventions intended to help relieve children’s distress. However, when large populations are affected and individuals suffer severe loss such as in a mass casualty disaster, the scale of events requires community-wide efforts to meet the needs of children and their families. The fact that some children are more psychosocially vulnerable than others will be discussed. The chapter will conclude by highlighting warning signs warranting professional mental health care

Determinants of recovery from post-COVID-19 dyspnoea: analysis of UK prospective cohorts of hospitalised COVID-19 patients and community-based controls

Background The risk factors for recovery from COVID-19 dyspnoea are poorly understood. We investigated determinants of recovery from dyspnoea in adults with COVID-19 and compared these to determinants of recovery from non-COVID-19 dyspnoea. Methods We used data from two prospective cohort studies: PHOSP-COVID (patients hospitalised between March 2020 and April 2021 with COVID-19) and COVIDENCE UK (community cohort studied over the same time period). PHOSP-COVID data were collected during hospitalisation and at 5-month and 1-year follow-up visits. COVIDENCE UK data were obtained through baseline and monthly online questionnaires. Dyspnoea was measured in both cohorts with the Medical Research Council Dyspnoea Scale. We used multivariable logistic regression to identify determinants associated with a reduction in dyspnoea between 5-month and 1-year follow-up. Findings We included 990 PHOSP-COVID and 3309 COVIDENCE UK participants. We observed higher odds of improvement between 5-month and 1-year follow-up among PHOSP-COVID participants who were younger (odds ratio 1.02 per year, 95% CI 1.01–1.03), male (1.54, 1.16–2.04), neither obese nor severely obese (1.82, 1.06–3.13 and 4.19, 2.14–8.19, respectively), had no pre-existing anxiety or depression (1.56, 1.09–2.22) or cardiovascular disease (1.33, 1.00–1.79), and shorter hospital admission (1.01 per day, 1.00–1.02). Similar associations were found in those recovering from non-COVID-19 dyspnoea, excluding age (and length of hospital admission). Interpretation Factors associated with dyspnoea recovery at 1-year post-discharge among patients hospitalised with COVID-19 were similar to those among community controls without COVID-19.

Clinical characteristics with inflammation profiling of long COVID and association with 1-year recovery following hospitalisation in the UK: a prospective observational study

Background No effective pharmacological or non-pharmacological interventions exist for patients with long COVID. We aimed to describe recovery 1 year after hospital discharge for COVID-19, identify factors associated with patient-perceived recovery, and identify potential therapeutic targets by describing the underlying inflammatory profiles of the previously described recovery clusters at 5 months after hospital discharge. Methods The Post-hospitalisation COVID-19 study (PHOSP-COVID) is a prospective, longitudinal cohort study recruiting adults (aged ≥18 years) discharged from hospital with COVID-19 across the UK. Recovery was assessed using patient-reported outcome measures, physical performance, and organ function at 5 months and 1 year after hospital discharge, and stratified by both patient-perceived recovery and recovery cluster. Hierarchical logistic regression modelling was performed for patient-perceived recovery at 1 year. Cluster analysis was done using the clustering large applications k-medoids approach using clinical outcomes at 5 months. Inflammatory protein profiling was analysed from plasma at the 5-month visit. This study is registered on the ISRCTN Registry, ISRCTN10980107, and recruitment is ongoing. Findings 2320 participants discharged from hospital between March 7, 2020, and April 18, 2021, were assessed at 5 months after discharge and 807 (32·7%) participants completed both the 5-month and 1-year visits. 279 (35·6%) of these 807 patients were women and 505 (64·4%) were men, with a mean age of 58·7 (SD 12·5) years, and 224 (27·8%) had received invasive mechanical ventilation (WHO class 7–9). The proportion of patients reporting full recovery was unchanged between 5 months (501 [25·5%] of 1965) and 1 year (232 [28·9%] of 804). Factors associated with being less likely to report full recovery at 1 year were female sex (odds ratio 0·68 [95% CI 0·46–0·99]), obesity (0·50 [0·34–0·74]) and invasive mechanical ventilation (0·42 [0·23–0·76]). Cluster analysis (n=1636) corroborated the previously reported four clusters: very severe, severe, moderate with cognitive impairment, and mild, relating to the severity of physical health, mental health, and cognitive impairment at 5 months. We found increased inflammatory mediators of tissue damage and repair in both the very severe and the moderate with cognitive impairment clusters compared with the mild cluster, including IL-6 concentration, which was increased in both comparisons (n=626 participants). We found a substantial deficit in median EQ-5D-5L utility index from before COVID-19 (retrospective assessment; 0·88 [IQR 0·74–1·00]), at 5 months (0·74 [0·64–0·88]) to 1 year (0·75 [0·62–0·88]), with minimal improvements across all outcome measures at 1 year after discharge in the whole cohort and within each of the four clusters. Interpretation The sequelae of a hospital admission with COVID-19 were substantial 1 year after discharge across a range of health domains, with the minority in our cohort feeling fully recovered. Patient-perceived health-related quality of life was reduced at 1 year compared with before hospital admission. Systematic inflammation and obesity are potential treatable traits that warrant further investigation in clinical trials.

Satisfaction and dimensions of control among call centre customer service representatives

The impact of the call centre workplace upon employee satisfaction or well-being is beginning to attract the attention of researchers. The aim of this paper is to explore the factors related to control and other work-based characteristics that impact upon employee well-being in call centres. Based on a survey (n=173), data are presented to highlight antecedents of employee well-being or job satisfaction in a call centre. Using factor analysis and regression modelling, we have isolated eight factors that are significantly associated with job satisfaction. Emotional pressure emerges as a significant as a dimension of control underpinning factors impacting upon job satisfaction. In addition, work-based characteristics including computer-facilitated and supervisory control associated with the role of the customer service representative (CSR) are shown to be direct antecedents of satisfaction. Another element of control, that of targets, emerged as a distinct factor, contributing indirectly to job satisfaction via its influence on work-based job characteristics. Much current research infers relatively low levels of satisfaction with both work and management on the part of customer service representatives (CSRs). The significance of our analysis resides partly in the qualification of the view that CSRs are subjected to, and perceive themselves as being victims at the 'sharp end' of, extreme technological control of the 'electronic panopticon' variety, itself based on a 'mass production of services' model. Moreover, much call centre work is considered relatively low-skilled, and much sociological research indicates that low-skilled work generally is not intrinsically satisfying and, indeed, employees look to extrinsic factors such as pay and job security as compensatory mechanisms. Following on from this, and even more significant for our purposes, is the argument that those call centre workers who generally regard themselves as playing a positive role within the wider organization, are regularly informed and valued by team leaders, and recognize the benefits of certain HRM practices, will have their view of the work situation ameliorated by those compensatory mechanisms. Given the validity of this argument, call centre work in certain circumstances may therefore accord more with the characteristics of 'mass customization' models. This is not to deny, however, the undoubted pressures of call centre work, which were commented upon by respondents and which still may represent the 'unacceptable face' of call centre culture

Genetic Diversity and Population Structure of Trypanosoma brucei in Uganda: Implications for the Epidemiology of Sleeping Sickness and Nagana

BACKGROUND:While Human African Trypanosomiasis (HAT) is in decline on the continent of Africa, the disease still remains a major health problem in Uganda. There are recurrent sporadic outbreaks in the traditionally endemic areas in south-east Uganda, and continued spread to new unaffected areas in central Uganda. We evaluated the evolutionary dynamics underpinning the origin of new foci and the impact of host species on parasite genetic diversity in Uganda. We genotyped 269 Trypanosoma brucei isolates collected from different regions in Uganda and southwestern Kenya at 17 microsatellite loci, and checked for the presence of the SRA gene that confers human infectivity to T. b. rhodesiense. RESULTS:Both Bayesian clustering methods and Discriminant Analysis of Principal Components partition Trypanosoma brucei isolates obtained from Uganda and southwestern Kenya into three distinct genetic clusters. Clusters 1 and 3 include isolates from central and southern Uganda, while cluster 2 contains mostly isolates from southwestern Kenya. These three clusters are not sorted by subspecies designation (T. b. brucei vs T. b. rhodesiense), host or date of collection. The analyses also show evidence of genetic admixture among the three genetic clusters and long-range dispersal, suggesting recent and possibly on-going gene flow between them. CONCLUSIONS:Our results show that the expansion of the disease to the new foci in central Uganda occurred from the northward spread of T. b. rhodesiense (Tbr). They also confirm the emergence of the human infective strains (Tbr) from non-infective T. b. brucei (Tbb) strains of different genetic backgrounds, and the importance of cattle as Tbr reservoir, as confounders that shape the epidemiology of sleeping sickness in the region
