Published: January 2021

Asthma is a common problem that affects about 20 million peoples in India and can be often under-diagnosed or misdiagnosed. It can be allergic or non-allergic though the former type is more common and prevalent. Allergic asthma can be triggered by many allergens and house dust mites (HDM) are one of the common indoor allergens. The present study emphasizes the significance of house dust mites in allergic asthmatic subjects which is based on 115 asthmatic subjects in Punjab, India. For the quantification and the estimation of total serum Immunoglobulin E and HDM specific IgE, a mixture of 14 allergens and a mixture of two mite allergens viz. Dermatophagoides pteronyssinus and D. farinae were used respectively. Total and specific IgE levels were detected on ImmunoCAP Phadia 100. A statistically significant correlation between total and HDM specific IgE levels of 115 asthmatic subjects was found as compared to control group of 30 non-allergic individuals. The specific IgE levels of 54.78% subjects against the allergen of two mite species were found to be positive. Dust samples were taken from various localities of the houses to identify the diversity of house dust mites which were responsible for allergic asthma. Five common house dust mite species viz. D. pteronyssinus Trouessart, D. farinae Hughes, D. microceras Griffiths and Cunnington, D. aureliani Fain and Euroglyphus maynei Cooreman were identified from the dust. The present study observed that total IgE levels were higher with higher specific IgE levels against the mixture of two mite allergens viz. D. pteronyssinus and D. farinae in the blood serum. D. pteronyssinus was the most abundant and prevalent mite species followed by D. farinae. Therefore, present study concluded that HDM specific IgE levels against the mite allergen of D. pteronyssinus and D. farinae in the serum of allergic asthmatic subjects were found to be higher because of the higher prevalence of these two mites (D. pteronyssinus i.e. 69.80% and D. farinae i.e. 20.72%) in the house of allergic asthmatic subjects as compared to other identified mites.

Fluid intake recommendations have been established for the athletic population in order to promote adequate hydration. The Beverage Intake Questionnaire (BEVQ-15) is a quick and reliable food frequency questionnaire that quantifies habitual beverage intake, which has been validated in children, adolescents, and adults. However, no validated beverage consumption questionnaire is available for collegiate athletes. Urine color (UC), while feasible for determining hydration status, has not been validated within a variety of collegiate athletes. The purpose of this investigation was to evaluate the comparative validity and reliability of pragmatic methods to rapidly assess BEVQ-15 and UC rating in U.S. Division I collegiate athletes. Student-athletes (n = 120; 54% females; age 19 ± 1 years) from two universities were recruited to complete three study sessions. At the first and third sessions, the participants completed the BEVQ-15 and provided a urine sample to determine UC and urinary specific gravity. All sessions included completion of a 24-hr dietary recall. Total fluid intake (fl oz) was 111 ± 107 and 108 ± 42 using the BEVQ-15 and the mean of three 24-hr dietary recalls, respectively, which was not different between methods (p > .05). There were moderate associations between the BEVQ-15 and dietary recall results for total beverage intake fl oz and kcal(r = .413 and r = 4.65; p ≤ .05, respectively). Strong associations were noted between both researcher-rated and participant-rated UC with urinary specific gravity measures (r = .675 and r = .884; p ≤ .05, respectively). Therefore, these rapid assessment methods demonstrated acceptable validity and may be used as practical methods to determine whether athletes are meeting their hydration recommendations.

BackgroundStudies describing body mass index (BMI) and prudent diet score have reported that they are associated between parents and children. The Hertfordshire Intergenerational Study, which contains BMI, diet and social class information across three generations, provides an opportunity to consider the influence of grandparental and parental BMI and prudent diet score across multiple generations, and the influence of grandparental and parental social class on child BMI.MethodsLinear regressions examining the tracking of adult BMI and prudent diet score across three generations (grandparent (F0), parent (F1) and child (F2)) were run from parent to child and from grandparent to grandchild. Linear mixed models investigated the influence of F0 and F1 BMI or prudent diet score on F2 BMI and prudent diet score. Linear regressions were run to determine whether social class and prudent diet score of parents and grandparents influenced the BMI of children and grandchildren.ResultsBMI was significantly associated across each generational pair and from F0 to F1 in multilevel models. Prudent diet score was significantly positively associated between grandparents and grandchildren. Lower grandparental and parental social class had a significantly positive association with F2 BMI (F0 low social class: b=1.188 kg/m2, 95% CI 0.060 to 2.315, p=0.039; F1 middle social class: b=2.477 kg/m2, 95% CI 0.726 to 4.227, p=0.006).ConclusionAdult BMI tracks across generations of the Hertfordshire Intergenerational Study, and child BMI is associated with parental and grandparental social class. The results presented here add to literature supporting behavioural and social factors in the transmission of BMI across generations.

ObjectiveNo recent large studies have described the distribution of vitamin D status in the UK. Understanding the epidemiology of vitamin D deficiency is important to inform targeted public health recommendations. This study aimed to investigate the distribution of factors associated with serum vitamin D status in a large national cohort.DesignA cross-sectional study.SettingThe UK Biobank, a prospective cohort study following the health and well-being of middle-aged and older adults recruited between 2006 and 2010.ParticipantsA total of 449 943 participants aged 40–69 years with measured serum vitamin D status were eligible for the analysis. Participants completed a questionnaire about sex, age, ethnic background, vitamin D supplementation, smoking, drinking and socioeconomic status.Primary and secondary outcome measuresWe investigated the distribution of serum vitamin D status and the association between demographic factors and vitamin D deficiency or insufficiency. Vitamin D deficiency was defined as a serum 25-hydroxyvitamin D level <25 nmol/L. Multivariable logistic regression was used to assess the association between demographic factors and vitamin D status.ResultsAsian (n=4297/8000, 53.7%) and black (n=2459/7046, 34.9%) participants had a higher proportion of vitamin D deficiency than white participants (n=50 920/422 907, 12%). During spring and winter, the proportion of vitamin D deficiency was higher across the UK and higher in the north than in the south. Male sex, abnormal body mass index, non-white ethnic backgrounds, smoking and being more socioeconomically deprived were associated with higher odds of vitamin D deficiency. Increasing age, taking vitamin D supplements and drinking alcohol were associated with lower odds of deficiency.ConclusionsVitamin D status varied among different ethnic groups and by season and geographical area within the UK. Taking supplements was associated with a lower risk of vitamin D deficiency. These findings support the vitamin D supplementation recommendations of Public Health England.

ObjectivesOur work aimed at exploring the relationship between cold spells and acute exacerbation of chronic obstructive pulmonary disease (AECOPD) hospitalisations in Beijing, China, and assessing the moderating effects of the intensities and the durations of cold spells, as well as identifying the vulnerable.DesignA time-series study.SettingWe obtained time-series data of AECOPD hospitalisations, meteorological variables and air quality index in Beijing, China during 2012–2016.ParticipantsAll AECOPD hospitalisations among permanent residents in Beijing, China during the cold seasons (November–March) of 2012–2016 were included (n=84 571).Primary and secondary outcome measuresA quasi-Poisson regression with a distributed lag model was fitted to investigate the short-term effects of cold spells on AECOPD hospitalisations by comparing the counts of AECOPD admissions during cold spell days with those during non-cold spell days.ResultsCold spells under different definitions were associated with increased risk of AECOPD hospitalisations, with the maximum cumulative relative risk (CRR) over 3 weeks (lag0–21). The cumulative effects at lag0–21 increased with the intensities and the durations of cold spells. Under the optimal definition, the most significant single-day relative risk (RR) was found on the days of cold spells (lag0) with an RR of 1.042 (95% CI 1.013 to 1.072), and the CRR at lag0–21 was 1.394 (95% CI 1.193 to 1.630). The elderly (aged ≥65) were more vulnerable to the effects of cold spells on AECOPD hospitalisations.ConclusionCold spells are associated with increased AECOPD hospitalisations in Beijing, with the cumulative effects increased with intensities and durations. The elderly are at particular risk of AECOPD hospitalisations triggered by cold spells.

Published: January 2021

ObjectivesExamine compliance with personal protective measures in communities for the prevention and control of local transmission of the COVID-19, and explore indicators for such behavioural compliance.DesignCross-sectional design with a self-selecting sample. Data collected in February 2020.SettingCommunity dwellers in China.Participants2956 participants aged 16 and above completed the study and were included in the analysis.Outcome measuresNationwide COVID-19 survey. Demographics and self-reported compliance with four personal protective measures—home quarantine, mask-wearing, temperature-taking and hand-sanitising were collected. Outbreak severity and timeliness of personal protection order were obtained from the China Center for Disease Control and Prevention website. Logistic regression models were employed to examine the association between demographic and social indicators and behavioural compliance.ResultsCompliance with home quarantine was only associated with gender (men, OR=0.61 (0.51–0.73), inverse association) but no other indicators. In contrast, men had higher compliance with mask-wearing (OR=1.79 (1.49–2.16)) and temperature-taking (OR=1.27 (1.05–1.53)). Compared with younger adults (≤20 years), the middle-age groups (31–40 and 41–50 years of age) were more compliant with all protective behaviours, except for home quarantine (OR=0.71 (0.54–0.93) and 0.67 (0.46–0.97), respectively).ConclusionMale gender was associated with lower compliance with home quarantine yet higher compliance with mask-wearing and temperature-taking. The middle-age participants (31–50 years) had lower compliance with home quarantine but higher with other measures. These findings may be supported by the economic considerations and the long-inherited Confucian values among Chinese. In light of the ongoing COVID-19 pandemic, public health authorities should tailor policy implementation to disparities in psychosocial indicators.

ObjectivesTo investigate the views and experiences of general practice of children with life-limiting and life-threatening conditions, and their family members, through secondary analysis of a qualitative serial interview study. Thematic analysis was conducted on all interview data relating to experiences of primary care.SettingWest Midlands, UK.ParticipantsA total of 31 participants (10 children with life-limiting and life-threatening conditions and 21 family members) from 14 families.Study design and settingSecondary thematic analysis of qualitative interview data from a study carried out in the West Midlands, UK.Method41 serial interviews with 31 participants from 14 families: 10 children aged 5–18 years with life-limiting and life-threatening conditions, and 21 of their family members.ResultsThree key themes emerged: (1) poor experiences of general practice cause children and families to feel isolated, (2) children and families value support from general practice, and (3) there are practical ways through which general practice has the potential to provide important aspects of care. Children and families reported benefits from fostering their relationship with their general practice in order to access important aspects of care, including the assessment and management of acute illness, chronic disease and medication reviews, and holistic support.ConclusionChildren with life-limiting and life-threatening conditions and their families value the involvement of general practice in the care, alongside their paediatric specialists. Ways of developing and providing such support as part of an integrated system of care need to be developed.

ObjectiveTo explore how to build and maintain the resilience of frontline healthcare professionals exposed to COVID-19 outbreak working conditions.DesignScoping review supplemented with expert interviews to validate the findings.SettingHospitals.MethodsWe searched PubMed, Embase, PsycINFO, CINAHL, bioRxiv and medRxiv systematically and grey literature for articles focusing on the impact of COVID-19-like working conditions on the physical and/or mental health of healthcare professionals in a hospital setting. Articles using an empirical design about determinants or causes of physical and/or mental health and about interventions, measures and policies to preserve physical and/or mental health were included. Four experts were interviewed to reflect on the results from the scoping review.ResultsIn total, 4471 records were screened leading to an inclusion of 73 articles. Recommendations prior to the outbreak fostering resilience included optimal provision of education and training, resilience training and interventions to create a feeling of being prepared. Recommendations during the outbreak consisted of (1) enhancing resilience by proper provision of information, psychosocial support and treatment (eg, create enabling conditions such as forming a psychosocial support team), monitoring the health status of professionals and using various forms and content of psychosocial support (eg, encouraging peer support, sharing and celebrating successes), (2) tasks and responsibilities, in which attention should be paid to kind of tasks, task mix and responsibilities as well as the intensity and weight of these tasks and (3) work patterns and working conditions. Findings of the review were validated by experts.ConclusionsRecommendations were developed on how to build and maintain resilience of frontline healthcare professionals exposed to COVID-19 outbreak working conditions. These practical and easy to implement recommendations can be used by hospitals and other healthcare organisations to foster and preserve short-term and long-term physical and mental health and employability of their professionals.
Return to employment for working-aged adults after burn injury: a scoping review protocol
Authors: Katsu Akane , Tyack Zephanie , Mackey Martin , Elliott James M , Mackenzie Lynette 
Published: January 2021

IntroductionCutaneous burns can have a catastrophic effect on people’s lives and may restrict opportunities for employment due to physical impairment and psychosocial deficits. Failure or delay in return to work can result in loss of income and support for the family unit. It can also negatively affect life role and identity and present difficulties with future opportunities. Current literature indicates multiple discrete influences on return to work as a result of burn injury but an understanding of how working-aged adults resume employment after burn injury is lacking. This scoping review will provide a comprehensive overview of the current literature by mapping and consolidating knowledge in this area of burn recovery and thus provide an informative basis for developing return-to-work programmes for survivors of burn injury.Methods and analysisThis scoping review protocol will follow the Arksey and O’Malley’s (2005) methodological framework. A comprehensive search strategy has been developed with subject expert librarians. These databases were used: OvidSP: Medline, Embase, PsycINFO, PubMed and Cochrane Central Register of Controlled Trials and EBSCOhost: CINAHL and Scopus. Reference lists of selected full text will be hand searched for additional literature. To enhance consistency and rigour, all reviewers will undertake a calibration exercise before paired reviewers independently screen all records using Rayyan. Full-text articles meeting the study inclusion criteria will be retrieved and examined. Extracted data will be analysed using the International Classification of Functioning, Disability and Health.Ethics and disseminationEthics approval is generally not required for scoping reviews. Findings of this scoping review will be reported in a peer-reviewed journal and presented at conferences.

Published: January 2021

BackgroundThe reported prevalence of chronic pain after spinal cord injury (SCI) varies widely due, in part, to differences in the taxonomy of chronic pain. A widely used classification system is available to describe subcategories of chronic pain in SCI, but the prevalence of chronic pain in SCI based on this system is unknown.ObjectiveThe primary objective of this systematic review and meta-analysis is to determine the prevalence of chronic pain after SCI based on the International Spinal Cord Injury Pain (ISCIP) classification system.Evidence reviewA comprehensive search of databases from January 1980 to August 2019 was conducted. The risk of bias was assessed using a modified tool developed for uncontrolled studies. The Grading of Recommendations, Assessment, Development and Evaluation approach was used to assess certainty in prevalence estimates.FindingsA total of 1305 records were screened, and 37 studies met inclusion criteria. The pooled prevalence of overall chronic pain was 68% (95% CI 63% to 73%). The pooled prevalence of neuropathic pain in 13 studies was 58% (95% CI 49% to 68%); the pooled prevalence of musculoskeletal pain in 11 studies was 56% (95% CI 41% to 70%); the pooled prevalence of visceral pain in 8 studies was 20% (95% CI 11% to 29%) and the pooled prevalence of nociceptive pain in 2 studies was 45% (95% CI 13% to 78%). Meta-regression of risk of bias (p=0.20), traumatic versus non-traumatic etiology of injury (p=0.59), and studies where pain was a primary outcome (p=0.32) demonstrated that these factors were not significant moderators of heterogeneity. Certainty in prevalence estimates was judged to be low due to unexplained heterogeneity.ConclusionThis systematic review and meta-analysis extends the findings of previous studies by reporting the prevalence of chronic pain after SCI based on the ISCIP classification system, thereby reducing clinical heterogeneity in the reporting of pain prevalence related to SCI.

Abstract

The existence of distinct breast microbiota has been recently established, but their biological impact in breast cancer remains elusive. Focusing on the shift in microbial community composition in diseased breast compared with normal breast, we identified the presence of Bacteroides fragilis in cancerous breast. Mammary gland as well as gut colonization with enterotoxigenic Bacteroides fragilis (ETBF), which secretes B. fragilis toxin (BFT), rapidly induces epithelial hyperplasia in the mammary gland. Breast cancer cells exposed to BFT exhibit “BFT memory” from the initial exposure. Intriguingly, gut or breast duct colonization with ETBF strongly induces growth and metastatic progression of tumor cells implanted in mammary ducts, in contrast to nontoxigenic Bacteroides fragilis. This work sheds light on the oncogenic impact of a procarcinogenic colon bacterium ETBF on breast cancer progression, implicates the β-catenin and Notch1 axis as its functional mediators, and proposes the concept of “BFT memory” that can have far-reaching biological implications after initial exposure to ETBF.

Significance:
B. fragilis is an inhabitant of breast tissue, and gut or mammary duct colonization with ETBF triggers epithelial hyperplasia and augments breast cancer growth and metastasis. Short-term exposure to BFT elicits a “BFT memory” with long-term implications, functionally mediated by the β-catenin and Notch1 pathways.
