ObjectiveCT quantification of aortic valve calcification (CT-AVC) is useful in the assessment of aortic stenosis severity. Our objective was to assess its ability to track aortic stenosis progression compared with echocardiography.MethodsSubjects were recruited in two cohorts: (1) a reproducibility cohort where patients underwent repeat CT-AVC or echocardiography within 4 weeks and (2) a disease progression cohort where patients underwent annual CT-AVC and/or echocardiography. Cohen’s d-statistic (d) was computed from the ratio of annualised progression and measurement repeatability and used to estimate group sizes required to detect annualised changes in CT-AVC and echocardiography.ResultsA total of 33 (age 71±8) and 81 participants (age 72±8) were recruited to the reproducibility and progression cohorts, respectively. Ten CT scans (16%) were excluded from the progression cohort due to non-diagnostic image quality. Scan-rescan reproducibility was excellent for CT-AVC (limits of agreement −12% to 10 %, intraclass correlation (ICC) 0.99), peak velocity (−7% to +17%; ICC 0.92) mean gradient (−25% to 27%, ICC 0.96) and dimensionless index (−11% to +15%; ICC 0.98). Repeat measurements of aortic valve area (AVA) were less reliable (−44% to +28%, ICC 0.85).CT-AVC progressed by 152 (65–375) AU/year. For echocardiography, the median annual change in peak velocity was 0.1 (0.0–0.3) m/s/year, mean gradient 2 (0–4) mm Hg/year and AVA −0.1 (−0.2–0.0) cm2/year. Cohen’s d-statistic was more than double for CT-AVC (d=3.12) than each echocardiographic measure (peak velocity d=0.71 ; mean gradient d=0.66; AVA d=0.59, dimensionless index d=1.41).ConclusionCT-AVC is reproducible and demonstrates larger increases over time normalised to measurement repeatability compared with echocardiographic measures.

ObjectivesThere has been a significant increase in syphilis in men who have sex with men (MSM) in the UK over the past 20 years. Partner notification strategies have increased the number of MSM attending STI clinics as sexual contacts of syphilis. Current guidelines suggest testing and consideration of presumptive antimicrobial treatment. Syphilis treatment with benzathine penicillin requires clinic resources, is painful and is associated with complications. It is important we consider strategies to rationalise presumptive antimicrobial use and promote antimicrobial stewardship.MethodsWe aimed to determine if there are any factors associated with having syphilis among MSM attending as sexual contacts of syphilis in a cross-sectional study. We examined the clinical records of MSM attending as sexual contacts of syphilis from January to December 2019.ResultsOf the 6613 MSM who attended for STI testing, 142 of 6613 (2.1%) presented as sexual contacts of syphilis. The median age was 40 years (IQR=31–51), 43 of 142 (30%) were HIV positive, 38 of 142 (27%) had been diagnosed and treated for syphilis in the past, and 11 of 142 (8%) presented with symptoms (possible lesions of primary or secondary syphilis). Thirteen (9%, 95% CI=4.4 to 13.9) tested positive for syphilis on the day of presentation. MSM who were symptomatic (genital ulcer or body rash), HIV positive or had a history of syphilis were significantly more likely to test positive for syphilis (OR=51.88, 95% CI: 3.01 to 893.14, p=0.007).ConclusionsWe have shown that in our clinic-based population of MSM who presented as sexual contacts of syphilis, the factors associated with testing positive for syphilis were: having HIV, having a history of syphilis or presenting with symptoms (possible lesions of primary or secondary syphilis). These factors could be used to rationalise antibiotic treatment among MSM presenting as sexual contacts of syphilis. Further research is needed to validate this finding in other populations of MSM and people affected by syphilis.

ObjectivesRates of HIV, syphilis and gonorrhoea have increased over the past 20 years in men who have sex with men (MSM). Contact tracing strategies have increased the number of MSM attending clinics as sexual contacts. Understanding the outcomes of contact tracing could inform future public health policies to reduce the burden of STIs in MSM.MethodWe aimed to describe the contribution of MSM attending as notified sexual contacts of patients with HIV, syphilis and gonorrhoea to the overall diagnoses of HIV, syphilis and gonorrhoea in MSM in a cross-sectional study. We collected data on all MSM diagnosed with HIV, syphilis and gonorrhoea in 2019 and evaluated which of these MSM were tested due to attending as a sexual contact.ResultsSexual contacts of HIV, syphilis and gonorrhoea contributed to 20% (95% CI=17.3% to 23.7%) of all diagnoses of HIV (3 of 30, 10%), syphilis (28 of 183, 15%) or gonorrhoea (98 of 420, 23%) in the study period. Asymptomatic sexual contacts contributed to 12% (95% CI=9.6% to 14.9%) of all diagnoses of HIV (3 of 30, 10%), syphilis (16 of 183, 9%) and gonorrhoea (57 of 420, 14%). The proportion of MSM diagnosed with gonorrhoea attending as sexual contacts of gonorrhoea (21%) was significantly greater than MSM diagnosed with HIV, attending as sexual contacts of HIV (3%) or MSM diagnosed with syphilis, attending as a sexual contact of syphilis (4%) (p<0.001). Furthermore, the proportion of MSM diagnosed with syphilis, attending as a sexual contact of another STI (11%) was significantly greater than MSM diagnosed with HIV, attending as a contact of another STI (7%) or MSM diagnosed with gonorrhoea, attending as a sexual contact of another STI (2%) (p<0.001).ConclusionContact tracing contributes significantly to the overall diagnoses of HIV, syphilis and gonorrhoea including asymptomatic sexual contacts in our population. Further efforts to increase the yield from contact tracing may continue to reduce the burden of HIV, syphilis and gonorrhoea within sexual networks of MSM.

Appropriate medication use is essential in ensuring optimal pharmacotherapeutic outcomes. It is mistakenly assumed that adults can swallow solid oral dosage forms (SODFs, e.g. tablets/capsules colloquially referred to as 'pills'), without difficulty and that children cannot. KidzMed is a 'pill swallowing' training programme designed to teach effective SODF use in patients of all ages. It may be utilised by healthcare professionals to assist patients taking SODFs. E-learning was essential for training during COVID pandemic to reduce viral transmission. The aim of this study was to explore UK student pharmacists views of e-learning to support swallowing solid oral dosage forms. This study used pre- and post-intervention online surveys on Microsoft Forms to evaluate self-directed eLearning about pill swallowing on MPharm programmes at three UK Universities using a 13-item survey. A combination of five-point Likert Scales and free-text items were used. The eLearning was available via the virtual learning environment at the University and embedded within existing curriculum. Descriptive statistical analysis was used to explore responses. In total, 113 of 340 (33%) students completed the survey. Seventy-eight percent (n = 65) reported the eLearning would enable them to teach adults and children to swallow SODFs successfully. Learners either agreed or strongly agreed that they felt comfortable to teach patients (95%, n = 62/113) and parents or carers (94%, n = 60) to swallow medications having completed the e-learning. Student pharmacists generally found eLearning as an acceptable way to reflect on their own experiences of 'pill' swallowing and how to support patients to swallow SODFs. The KidzMed eLearning was well received by student pharmacists. Further work is needed to explore whether skills translates into real life application in the clinical settings.

ObjectiveTo estimate the effect of a physiotherapist-delivered fall prevention programme for people with Parkinson’s (PwP).MethodsPeople at risk of falls with confirmed Parkinson’s were recruited to this multicentre, pragmatic, investigator blind, individually randomised controlled trial with prespecified subgroup analyses. 474 PwP (Hoehn and Yahr 1–4) were randomised: 238 allocated to a physiotherapy programme and 236 to control. All participants had routine care; the control group received a DVD about Parkinson’s and single advice session at trial completion. The intervention group (PDSAFE) had an individually tailored, progressive home-based fall avoidance strategy training programme with balance and strengthening exercises. The primary outcome was risk of repeat falling, collected by self-report monthly diaries, 0–6 months after randomisation. Secondary outcomes included Mini-BESTest for balance, chair stand test, falls efficacy, freezing of gait, health-related quality of life (EuroQol EQ-5D), Geriatric Depression Scale, Physical Activity Scale for the Elderly and Parkinson’s Disease Questionnaire, fractures and rate of near falling.ResultsAverage age is 72 years and 266 (56%) were men. By 6 months, 116 (55%) of the control group and 125 (61.5%) of the intervention group reported repeat falls (controlled OR 1.21, 95% CI 0.74 to 1.98, p=0.447). Secondary subgroup analyses suggested a different response to the intervention between moderate and severe disease severity groups. Balance, falls efficacy and chair stand time improved with near falls reduced in the intervention arm.ConclusionPDSAFE did not reduce falling in this pragmatic trial of PwP. Other functional tasks improved and reduced fall rates were apparent among those with moderate disease.Trial registration number ISRCTN48152791.

Since 2018, there has been no requirement to bring decisions about the withdrawal of clinically-assisted nutrition and hydration (CANH) in patients with persistent disorders of consciousness before the courts, providing that the requirements of the Mental Capacity Act 2005 (MCA) are fulfilled. Subsequent British Medical Association and Royal College of Physicians guidance on CANH withdrawal recommended standards of record keeping and internal and external audit to ensure local decision making was compliant with the MCA to safeguard patients. The scope of the guidance also included patients with stroke and neurodegenerative disorders. Freedom of Information requests made 2 years after the introduction of this guidance have shown that none of the NHS trusts or clinical commissioning groups who responded were undertaking any systematic monitoring of these decisions. Neither is the Care Quality Commission reviewing these decisions, as there is ‘no statutory requirement’ to do so. It appears there is a lack of organised scrutiny of these highly complex life-ending treatment decisions. This omission must surely be a cause for concern.

Exclusive breastfeeding (EBF)—giving infants only breast-milk (and medications, oral rehydration salts and vitamins as needed) with no additional food or drink for their first six months of life—is one of the most effective strategies for preventing child mortality 1 – 4 . Despite these advantages, only 37% of infants under 6 months of age in Africa were exclusively breastfed in 2017 5 , and the practice of EBF varies by population. Here, we present a fine-scale geospatial analysis of EBF prevalence and trends in 49 African countries from 2000–2017, providing policy-relevant administrative- and national-level estimates. Previous national-level analyses found that most countries will not meet the World Health Organization’s Global Nutrition Target of 50% EBF prevalence by 2025 6 . Our analyses show that even fewer will achieve this ambition in all subnational areas. Our estimates provide the ability to visualize subnational EBF variability and identify populations in need of additional breastfeeding support. Exclusive breastfeeding in Africa is highly varied within and between countries, with many countries unlikely to reach World Health Organization 2025 targets without urgent action.

IntroductionIn Liberia, emergency care is still in its early development. In 2019, two emergency care and triage education sessions were done at J. J. Dossen Hospital in Southeastern Liberia. The observational study objectives evaluated key process outcomes before and after the educational interventions.MethodsEmergency department paper records from 1 February 2019 to 31 December 2019 were retrospectively reviewed. Simple descriptive statistics were used to describe patient demographics and χ2 analyses were used to test for significance. ORs were calculated for key predetermined process measures.ResultsThere were 8222 patient visits recorded that were included in our analysis. Patients in the post-intervention 1 group had higher odds of having a documented full set of vital signs compared with the baseline group (16% vs 3.5%, OR: 5.4 (95% CI: 4.3 to 6.7)). After triage implementation, patients who were triaged were 16 times more likely to have a full set of vitals compared with those who were not triaged. Similarly, compared with the baseline group, patients in the post-intervention 1 group had higher odds of having a glucose documented if they presented with altered mental status or a neurologic complaint (37% vs 30%, OR: 1.7 (95% CI: 1.3 to 2.2)), documented antibiotic administration if they had a presumed bacterial infection (87% vs 35%, OR: 12.8 (95% CI: 8.8 to 17.1)), documented malaria test if presenting with fever (76% vs 61%, OR: 2.05 (95% CI: 1.37 to 3.08)) or documented repeat set of vitals if presenting with shock (25% vs 6.6%, OR: 8.85 (95% CI: 1.67 to 14.06)). There was no significant difference in the above process outcomes between the education interventions.ConclusionThis study showed improvement in most process measures between the baseline and post-intervention 1 groups, benefits that persisted post-intervention 2, thus supporting the importance of short-course education interventions to durably improve facility-based care.

Clinicians often lack key information regarding intensive care unit (ICU) families. Our objective was to identify (1) important information for clinicians to know about ICU families when making decisions and (2) important information for families to know about patients from clinicians. We identified important information items through a literature review and semistructured interviews. A separate cohort of family members, nurses, and physicians from 2 ICUs in a single institution were asked to prioritize the identified information as necessary for decision making. We identified 21 items important for clinicians to know about families and 32 items important for families to know about patients from clinicians. Themes important for clinicians to know about family members included family background, questions, understanding, goals, concerns, well-being, and requests for additional help. Themes important for families to know about the patient included diagnosis, treatments, prognosis, clinical status, schedule, comfort, goals of care, medical team, and family participation. Through qualitative and quantitative analysis, we identified important information for ICU clinicians to know about family members and for family members to know about patients. The identified information can be used to guide strategies and tools to improve assessment of and communication with families.
