Given the budgetary restrictions on scientific research and the increasing need to better inform conservation actions, it is important to identify the patterns and causes of biases in research effort. We combine bibliometric information from a literature review of almost 16,500 peer-reviewed publications on a well-known group of 286 species, the Order Carnivora, with global datasets on species' life history and ecological traits to explore patterns in research effort. Our study explores how species' characteristics influenced the degree to which they were studied (measured as the number of publications). We identified a wide variation in intensity of research effort at both Family and Species levels, with some of the least studied being those which may need protection in future. Our findings hint at the complex role of human perspectives in setting research agendas. We found that better-studied species tended to be large-bodied and have a large geographic range whilst omnivory had a negative relationship with research effort. IUCN threat status did not exhibit a strong relationship with research effort which suggests that the conservation needs of individual species are not major drivers of research interest. This work is the first to use a combination of bibliometric analysis and biological data to quantify and interpret gaps in research knowledge across an entire Order. Our results could be combined with other resources, such as Biodiversity Action Plans, to prioritise and co-ordinate future research effort, whilst our methods can be applied across many scientific disciplines to describe knowledge gaps.
Background: Transgender men and non-binary people assigned female at birth (TMNB) who have not had surgery to remove the cervix are recommended to undertake cervical screening with the same frequency as cisgender women but evidence suggests that TMNB have lower odds of lifetime and up-to-date cervical screening uptake. Aim: To understand the attitudes towards and preferences for cervical screening among UK-based TMNB. Design & Setting: Cross-sectional survey of TMNB at an NHS gender identity clinic (GIC) and an NHS sexual health service specialising in care of transgender people. Method: Recruitment was via email invitations to patients of the GIC and sexual health service. Inclusion criteria were: female sex assigned at birth, trans man, masculine, or non-binary gender identity, age ≥18 and UK resident. Quantitative results were analysed using descriptive statistics and free text comments were analysed thematically. Results: There were 137 participants, 79% identifying as transmasculine and 18% as non-binary. Sixty-five participants (46%) were eligible for cervical screening and 56.9% of those had ever been screened. Only 53.1% of those eligible felt they had sufficient information about cervical screening . Just over half (53%) stated they would like the option to self-swab for high-risk HPV. Only half of the participants were in favour of an automatic invitation for cervical screening . Thematic analysis identified a number of additional barriers and facilitators of screening. Conclusions: TMNB have identified numerous potential areas for change that may improve cervical screening uptake and patient experience.
Background Lesbian, gay, bisexual and transgender (LGBT) patients have an increased incidence of a range of health problems, and face many barriers to accessing healthcare. Our research aimed to explore the awareness of health issues and attitudes of medical students towards LGBT patients’ health including barriers to health services, their attitudes towards inclusion of LGBT content in the curriculum and their confidence with providing care for their LGBT patients in the future. Methods Medical students were recruited to take part in a cross-sectional survey. We used a 28-item survey to explore views about the undergraduate medical curriculum. Results 252 surveys were analysed from 776 eligible participants. Attitudes towards LGBT patients were positive but awareness and confidence with respect to LGBT patients were variable. Confidence discussing sexual orientation with a patient significantly increased with year of study but confidence discussing patient gender identity did not. The majority of participants (n = 160; 69%) had not received specific training on LGBT health needs, and 85% (n = 197) wanted to receive more training. Conclusions Increasing the amount of LGBT teaching in undergraduate medical curricula could help to increase the quality of doctor-patient interactions, to facilitate patients’ disclosure of sexual orientation and gender identity in healthcare and increase the quality of healthcare.
We observed significant differences in adjusted mortality between hospitals, suggesting differences in quality of care. However, mortality is strongly influenced by patient mix and thus, crude mortality is not a suitable quality indicator.
Predicting protective immunity based on isolated HCMV subunit-specific T-cell responses is questionable in light of the complex architecture of the overall response. Our findings have important implications for T-cell monitoring, intervention strategies, as well as the application of animal models to the understanding of human infection.
ObjectiveWe recently showed that a urine albumin/total protein ratio (uAPR) < 0.4 identifies tubular pathology in proteinuric patients. In tubular disorders, proteinuria is usually of low molecular weight and contains relatively little albumin. We tested the hypothesis that uAPR is useful in identifying tubular pathology related to antiretroviral use in HIV-infected patients. MethodsWe retrospectively identified urine protein/creatinine ratios (uPCRs) in HIV-infected patients. A subset of samples had uPCR and urine albumin/creatinie ratio (uACR) measured simultaneously. We classified proteinuric patients (uPCR > 30 mg/mmol) into two groups: those with predominantly 'tubular' proteinuria (TP) (uAPR < 0.4) and those with predominantly 'glomerular' proteinuria (GP) (uAPR Ն 0.4). ResultsA total of 618 of 5244 samples from 1378 patients had uPCR Ն 30 mg/mmol. uAPRs were available in 144 patients: 46 patients (32%) had TP and 21 (15%) GP; the remainder had uPCR < 30 mg/mmol. The TP group had a higher fractional excretion of phosphate compared with the GP group (mean 27% vs. 16%, respectively; P < 0.01). Patients with TP were more likely to be on tenofovir and/or a boosted protease inhibitor compared with those with GP. In 18 patients with heavy proteinuria (uPCR > 100 mg/mmol), a renal assessment was made; eight had a kidney biopsy. In all cases, the uAPR results correlated with the nephrological diagnosis. ConclusionsIn HIV-infected patients, measuring uAPR may help to identify patients in whom a renal biopsy is indicated, and those in whom tubular dysfunction might be an important cause of proteinuria and which may be related to antiretroviral toxicity. We suggest that this would be useful as a routine screening procedure in patients with proteinuria.
Evidence before this study: Acute appendicitis is the most common general surgical emergency in children. Its diagnosis remains challenging and children presenting with acute right iliac fossa (RIF) pain may be admitted for clinical observation or undergo normal appendicectomy (removal of a histologically normal appendix). A search for external validation studies of risk prediction models for acute appendicitis in children was performed on MEDLINE and Web of Science on 12 January 2017 using the search terms ["appendicitis" OR "appendectomy" OR "appendicectomy"] AND ["score" OR "model" OR "nomogram" OR "scoring"]. Studies validating prediction models aimed at differentiating acute appendicitis from all other causes of RIF pain were included. No date restrictions were applied. Validation studies were most commonly performed for the Alvarado, Appendicitis Inflammatory Response Score (AIRS), and Paediatric Appendicitis Score (PAS) models. Most validation studies were based on retrospective, single centre, or small cohorts, and findings regarding model performance were inconsistent. There was no high quality evidence to guide selection of the optimum model and threshold cutoff for identification of low-risk children in the UK and Ireland. Added value of this study: Most children admitted to hospital with RIF pain do not undergo surgery. When children do undergo appendicectomy, removal of a normal appendix (normal appendicectomy) is common, occurring in around 1 in 6 children. The Shera score is able to identify a large low-risk group of children who present with acute RIF pain but do not have acute appendicitis (specificity 44%). This low-risk group has an overall 1 in 30 risk of acute appendicitis and a 1 in 270 risk of perforated appendicitis. The Shera score is unable to achieve a sufficiently high positive predictive value to select a high-risk group who should proceed directly to surgery. Current diagnostic performance of ultrasound is also too poor to select children for surgery. Implications of all the available evidence: Routine pre-operative risk scoring could inform shared decision making by doctors, children, and parents by supporting safe selection of lowrisk patients for ambulatory management, reducing unnecessary admissions and normal appendicectomy. Hospitals should ensure seven-day-a-week availability of ultrasound for medium and high-risk patients. Ultrasound should be performed by operators trained to assess for acute appendicitis in children. For children in whom diagnostic uncertainty remains following ultrasound, magnetic resonance imaging (MRI) or low-dose computed tomography (CT) are second-line investigations.
The People Living with HIV StigmaSurvey UK 2015 was a community led national survey investigating experiences of people living with HIV in the UK in the past 12 months. Participants aged 18 and over were recruited through over 120 cross-sector community organisations and 46 HIV clinics to complete an anonymous online survey. Trans is an umbrella term which refers to individuals whose current gender identity is different to the gender they were assigned at birth. Trans participants self-identified via gender identity and gender at birth questions. Descriptive analyses of reported experiences in social and health care settings were conducted and multivariate logistic regression analyses were used to identify sociodemographic predictors of reporting being treated differently to non-HIV patients, and being delayed or refused healthcare treatment in the past 12 months. 31 out of 1576 participants (2%) identified as trans (19 trans women, 5 trans men, 2 gender queer/non-binary, 5 other). High levels of social stigma were reported for all participants, with trans participants significantly more likely to report worrying about verbal harassment (39% vs. 23%), and exclusion from family gatherings (23% vs. 9%) in the last 12 months, compared to cisgender participants. Furthermore, 10% of trans participants reported physical assault in the last 12 months, compared to 4% of cisgender participants. Identifying as trans was a predictor of reporting being treated differently to non-HIV patients (48% vs. 30%; aOR 2.61, CI 1.06, 6.42) and being delayed or refused healthcare (41% vs. 16%; aOR 4.58, CI 1.83, 11.44). Trans people living with HIV in the UK experience high levels of stigma and discrimination, including within healthcare settings, which is likely to impact upon health outcomes. Trans-specific education and awareness within healthcare settings could help to improve service provision for this demographic.
