The aim of this study was to estimate the prevalence and severity of feeding and nutritional problems in children with neurological impairment within a defined geographical area. In a cross-sectional study, a validated questionnaire was sent to 377 parents of children (aged 4 to 13 years) on the Oxford Register of Early Childhood Impairments with oromotor dysfunction. The return rate was 72%. Of these, 93% had cerebral palsy; 47% were unable to walk; 78% had speech difficulty; and 28% continuous drooling of saliva. Gastrointestinal problems were commonly encountered: 59% were constipated; 22% had significant problems with vomiting, and 31% had suffered at least one chest infection in the previous 6 months. Feeding problems were prevalent: 89% needed help with feeding and 56% choked with food; 20% of parents described feeding as stressful and unenjoyable. Prolonged feeding times (3h/day) were reported by 28%. Only 8% of participants received caloric supplements and 8% were fed via gastrostomy tube. Even though 38% of respondents considered their child to be underweight, 64% of children had never had their feeding and nutrition assessed. The results highlight that feeding problems in children with neurological impairment are common and severe, causing parental concern. Many of these children would benefit from nutritional assessment and management as part of their overall care.

Poor nutritional status and growth failure are common in children with cerebral palsy (CP). The aim of this study was to assess, within a subgroup of a large and clearly defined population of children with disabilities, the impact of feeding difficulties on (1) the quality (micronutrient intake) and quantity (macronutrient intake) of their diet and (2) their growth. One hundred children with disabilities (40 females, 60 males; mean age 9 years, SD 2 years 5 months; range 4 years 6 months to 13 years 7 months) underwent a detailed dietetic analysis and a comprehensive anthropometric assessment. Diagnostic categories of disability were: CP (n=90); global developmental delay (n=3); Marfan syndrome (n=1); intractable epilepsy (n=2); agenesis of the corpus callosum (n=2); methyl malonic aciduria (n=1); and congenital rubella (n=1). Neurological impairment was classified according to difficulty with mobility which was graded as mild (little or no difficulty walking), moderate (difficulty walking but does not need aids or a helper), and severe (needs aids and/or a helper or cannot walk). Results confirmed the significant impact of neurological impairment in children on body growth and nutritional status becoming worse in those with a greater degree of motor impairment. The major nutritional deficit was in energy intake, with only one fifth reportedly regularly achieving over 100% estimated average requirement (EAR), whilst micronutrient intake was less markedly impaired and protein intake was normal in this group (96% above EAR). Many children with neurological impairment would benefit from individual nutritional assessment and management as part of their overall care.

AimTo determine whether QuantiFERON®-TB Gold In-Tube (QFT) can contribute to the diagnosis of active tuberculosis (TB) in children in a high-burden setting and to assess the performance of QFT and tuberculin skin test (TST) in a prospective cohort of TB suspect children compared to adults with confirmed TB in Tanzania.MethodsSensitivity and specificity of QFT and TST for diagnosing active TB as well as indeterminate QFT rates and IFN-γ levels were assessed in 211 TB suspect children in a Tanzanian district hospital and contrasted in 90 adults with confirmed pulmonary TB.ResultsSensitivity of QFT and TST in children with confirmed TB was 19% (5/27) and 6% (2/31) respectively. In adults sensitivity of QFT and TST was 84% (73/87) and 85% (63/74). The QFT indeterminate rate in children and adults was 27% and 3%. Median levels of IFN-γ were lower in children than adults, particularly children <2 years and HIV infected. An indeterminate result was associated with age <2 years but not malnutrition or HIV status. Overall childhood mortality was 19% and associated with an indeterminate QFT result at baseline.ConclusionQFT and TST showed poor performance and a surprisingly low sensitivity in children. In contrast the performance in Tanzanian adults was good and comparable to performance in high-income countries. Indeterminate results in children were associated with young age and increased mortality. Neither test can be recommended for diagnosing active TB in children with immature or impaired immunity in a high-burden setting.

Virtual Reality nonfiction (VRNF) is an emerging form of immersive media experience created for consumption using panoramic "Virtual Reality" headsets. VRNF promises nonfiction content producers the potential to create new ways for audiences to experience "the real"; allowing viewers to transition from passive spectators to active participants. Our current project is exploring VRNF through a series of ethnographic and experimental studies. In order to document the content available, we embarked on an analysis of VR documentaries produced to date. In this paper, we present an analysis of a representative sample of 150 VRNF titles released between 2012-2018. We identify and quantify 64 characteristics of the medium over this period, discuss how producers are exploiting the affordances of VR, and shed light on new audience roles. Our findings provide insight into the current state of the art in VRNF and provide a digital resource for other researchers in this area.

BackgroundDiagnosing tuberculosis in children remains a great challenge in developing countries. Health staff working in the front line of the health service delivery system has a major responsibility for timely identification and referral of suspected cases of childhood tuberculosis. This study explored primary health care staff's perception, challenges and needs pertaining to the identification of children with tuberculosis in Muheza district in Tanzania.MethodsWe conducted a qualitative study that included 13 semi-structured interviews and 3 focus group discussions with a total of 29 health staff purposively sampled from primary health care facilities. Analysis was performed in accordance with the principles of a phenomenological analysis.ResultsPrimary health care staff perceived childhood tuberculosis to be uncommon in the society and tuberculosis was rarely considered as a likely differential diagnosis. Long duration and severe signs of disease together with known exposure to tuberculosis were decisive for the staff to suspect tuberculosis in children and refer them to hospital. None of the staff felt equipped to identify cases of childhood tuberculosis and they experienced lack of knowledge, applicable tools and guidelines as the main challenges. They expressed the need for more training, supervision and referral feedback to improving case identification.ConclusionsInadequate awareness of the burden of childhood tuberculosis, limited knowledge of the wide spectrum of clinical presentation and lack of clinical decision support strategies is detrimental to the health staff's central responsibility of suspecting and referring children with tuberculosis especially in the early disease stages. Activities to improve case identification should focus on skills required by primary health care staff to fulfil their responsibility and reflect primary health care level capacities and challenges.

WHAT'S KNOWN ON THIS SUBJECT: IP-10 is a novel immunologic marker for tuberculosis (TB) infection. It has been suggested that IP-10 may perform better in children compared with the QuantiFERON test, but only a few studies have investigated IP-10 for diagnosing active TB in children. WHAT THIS STUDY ADDS:This study is the first to investigate IP-10 and QuantiFERON for diagnosing TB in children by using consensus classifications. Both IP-10 and QuantiFERON exhibited poor performance in children from a high-burden setting, and performance was especially compromised in young children. METHODS:Hospitalized Tanzanian children with symptoms of TB were tested with the QFT-IT and IP-10 tests and retrospectively classified into diagnostic groups. Adults with confirmed TB were assessed in parallel. RESULTS:A total of 203 children were included. The median age was 3.0 years (interquartile range: 1.2-7.0), 38% were HIV infected, 36% were aged ,2 years, and 58% had a low weight-for-age. IP-10 and QFT-IT test performance was comparable but sensitivity was low: 33% (1 of 3) in children with confirmed TB and 29% (8 of 28) in children with probable TB. Rates of indeterminate responders were high: 29% (59 of 203) for IP-10 and 26% (53 of 203) for QFT-IT. Age ,2 years was associated with indeterminate test outcome for both IP-10 (adjusted odds ratio [aOR]: 2.2; P = .02) and QFT-IT (aOR: 2.4; P = .01). TB exposure was associated with positive IP-10 test outcome (aOR: 3.6; P = .01) but not with positive QFT-IT outcome (aOR 1.4; P = .52). In 102 adults, test sensitivity was 80% for both tests (P = .248).
