Knowledge, attitudes and practices relating to antibiotic use and resistance among prescribers from public primary healthcare facilities in Harare, Zimbabwe

Background Overuse of antibiotics is one of the main drivers for antimicrobial resistance (AMR). Globally, most antibiotics are prescribed in the outpatient setting. This survey aimed to explore attitudes and practices with regards to microbiology tests, AMR and antibiotic prescribing among healthcare providers at public primary health clinics in Harare, Zimbabwe. Methods This cross-sectional survey was conducted in nine primary health clinics located in low-income suburbs of Harare between October and December 2020. In Zimbabwe, primary health clinics provide nurse-led outpatient care for acute and chronic illnesses. Healthcare providers who independently prescribe antibiotics and order diagnostic tests were invited to participate. The survey used self-administered questionnaires. A five-point Likert scale was used to determined attitudes and beliefs. Results A total of 91 healthcare providers agreed to participate in the survey. The majority of participants (62/91, 68%) had more than 10 years of work experience. Most participants reported that they consider AMR as a global (75/91, 82%) and/or national (81/91, 89%) problem, while 52/91 (57%) considered AMR to be a problem in their healthcare facilities. A fifth of participants (20/91, 22%) were unsure if AMR was a problem in their clinics. Participants felt that availability of national guidelines (89/89, 100%), training sessions on antibiotic prescribing (89/89, 100%) and regular audit and feedback on prescribing (82/88, 93%) were helpful interventions to improve prescribing. Conclusions These findings support the need for increased availability of data on AMR and antibiotic use in primary care. Educational interventions, regular audit and feedback, and access to practice guidelines may be useful to limit overuse of antibiotics.

Antibiotics, rational drug use and the architecture of global health in Zimbabwe

Rising concerns around antimicrobial resistance (AMR) have led to a renewed push to rationalise antibiotic prescribing in low- and middle-income countries (LMICs). There is increasing unease in conceptualising antibiotic use as individuals behaving '(ir)rationally' and recognition that rising use is emergent of and contributing to wider economic and political challenges. But in between these individual and societal 'drivers' of antibiotic use is an everyday articulation of care through these substances, written-in to the scripts, delivery chains and pedagogics of global healthcare. This article focuses on this everyday 'architecture' that over time and across spaces has knitted-in antibiotics and rhetorics of control that inform current responses to AMR. Based on historically informed ethnographic research in Zimbabwe, we examine points of continuity and change between 20th Century rational drug use (RDU) discourses and contemporary socio-political formations around AMR and antimicrobial stewardship (AMS), paying particular attention to their co-evolution with the process of pharmaceuticalisation. We illustrate how the framework and techniques of RDU were embedded within programmes to increase access to essential medicines and as such complemented the building of one of Africa's strongest postcolonial health systems in Zimbabwe. Whilst 20th Century RDU was focused on securing the health and safety of patients and affordability for systems, AMS programmes aim to secure medicines. Continuous through both RDU and AMS programmes is the persistent rhetoric of 'irrational use'. Health workers in Harare, attuned to the values and language of these programmes, enact in their everyday practice an architecture in which antibiotics have been designed-in. This research illustrates the struggle to optimise antibiotic use within current framings for action. We propose a reconfiguring of the architecture of global health such that frontline prescribers are able to provide 'good' care without necessarily turning to antibiotics. To design-out antibiotic reliance would require attention beyond '(ir)rationality', to the redrafting of blueprints that inscribe practice.

Test-retest reliability of the two-point discrimination test on the sole of the foot in people with multiple sclerosis

BACKGROUND

Two-point discrimination (TPD) is an assessment of tactile acuity. People with multiple sclerosis (MS) can have reduced foot sole tactile acuity, which has been linked to impaired balance.

OBJECTIVE

To quantify the test-retest reliability of TPD on the sole of the foot in people with MS.

APPROACH

41 participants (32 females), with mean (SD) age of 60 (9) years, and Expanded Disability Status Scale of <7.5, had their TPD measured at the head of the first metatarsal and the heel on two occasions, 2-14 d apart. Mean systematic change, within-subjects SD, limits of agreement (LOA), coefficient of variation and the intraclass correlation coefficient (ICC) were quantified as point estimates (95% CI).

MAIN RESULTS

Systematic learning effects were evident. The within-subjects SD at the metatarsal and the heel was 6.7 mm (5.5-8.6) and 8.3 mm (6.7-10.8), and the LOAs were 18.6 mm (15.2-24.) and 23.7 mm (18.7-30.1), respectively. ICCs for metatarsal and heel was 0.87 (0.76-0.93) and 0.90 (0.80-0.95), respectively, but these were likely inflated by sample heterogeneity.

SIGNIFICANCE

In people with MS, TPD on the sole of the foot has an adequate test-retest reliability for research purposes, but there is substantial measurement variability for individual patients.

Visual conditions affecting eye growth alter diurnal levels of vitreous DOPAC

In chicks, the diurnal patterns of retinal dopamine synthesis and release are associated with refractive development. To assess the within-day patterns of dopamine release, we assayed vitreal levels of DOPAC (3,4-dihydroxyphenylacetic acid) using high performance liquid chromatography with electrochemical detection, at 4-h intervals over 24 h in eyes with experimental manipulations that change ocular growth rates. Chicks were reared under a 12 h light/12 h dark cycle; experiments began at 12 days of age. Output was assessed by modelling using the robust variance structure of Generalized Estimating Equations. Continuous spectacle lensdefocus or form deprivation: One group experienced non-restricted visual input to both eyes and served as untreated "normal" controls. Three experimental cohorts underwent monocular visual alterations known to alter eye growth and refraction: wearing a diffuser, a negative lens or a positive lens. After one full day of device-wear, chicks were euthanized at 4-h intervals over 24 h (8 birds per time/condition). Brief hyperopic defocus: Chicks wore negative lenses for only 2 daily hours either in the morning (starting at ZT 0; n = 16) or mid-day (starting at ZT 4; n = 8) for 3 days. Vitreal DOPAC was assayed. In chicks with bilateral non-restricted vision, or with continuous defocus or form-deprivation, there was a diurnal variation in vitreal DOPAC levels for all eyes (p < 0.001 for each). In normal controls, DOPAC was highest during the daytime, lowest at night, and equivalent for both eyes. In experimental groups, regardless of whether experiencing a growth stimulatory input (diffuser; negative lens) or growth inhibitory input (positive lens), DOPAC levels were reduced compared both to fellow eyes and to those of normal controls (p < 0.001 for each). These diurnal variations in vitreous DOPAC levels under different visual conditions indicate a complexity for dopaminergic mechanisms in refractive development that requires further study.

O-Health-Edu: Advancing oral health: A vision for dental education

The prevalence and burden of untreated oral diseases throughout the life course remains high worldwide, and inequalities in oral health and dental care are increasing. This is a major public health issue that is not being enough addressed by the health care systems. To better manage populations' oral health, oral health professionals must be trained to adapt to population needs and societal and technological changes. Furthermore, dental institutions must fulfill their social responsibility by prioritizing educational and research activities that promote advancing individual and community health. In Europe, great variability exists between dental programs within the same country or between countries. This variability is an issue as European graduates can practice around the European Union through mutual recognition of their qualifications. This might lead to inequities in the availability, accessibility, acceptability and quality of health services. The convergence of competencies and quality standards at the international level must thus be better clearly identified, defined and improved. The purpose of the O-Health-Edu, EU funded project, “Advancing Oral Health: A vision for Dental Education” is thus to assess the current situation concerning the oral health professionals' education (OHP) and to identify educational priorities so that future graduating OHPs have competencies aligned with emerging population needs. The project is supported within the KA203 - “Cooperation for Innovation and the Exchange of Good Practices - Strategic Partnerships for higher education” Erasmus program. It began in October 2019 for three years, with eight European university partners and the ADEE (Association for Dental Education in Europe). The firsts steps consist of a scoping review to identify the available information followed by a questionnaire survey to gather more comprehensive data so that to build an opened data source, and a glossary of dental education terms.

Key messages

Few Information about the current situation of dental education in Europe. Graduates must be equipped with adequate competencies to face populations needs.

Opening up ‘fever’, closing down medicines

Rising concerns about antimicrobial resistance have sparked a renewed push to rationalise and ration the use of medicines. This article explores the case of the Integrated Management of Childhood Illness (IMCI) guideline, a periodically updated ‘global’ algorithm that shapes and normalises the centrality of medicines to care in low- and middle-income countries and, increasingly, the imperative to ration them. Using ‘classification work’ as analytic frame, we firstly consider the IMCI algorithm as a blueprint for global health that classifies illnesses, patients, and care in particular ways relative to available medicines. Zooming in on this blueprint, we then offer a classificatory reading of ‘fever’ over time, tracing ‘nonmalarial fever’ from being malaria’s residual ‘other’ category to becoming increasingly legible through attention to diagnostics and antibiotic (over)use. Our reading suggests that an apparent refinement of the ‘fever’ category may concurrently entail the closing down of medicine options. This raises the possibility that an increasingly high-tech but ‘empty’ form of pharmaceuticalised care is being incidentally worked into the infrastructure of weak health systems.

The role of intraoperative cholangiography in patients undergoing laparoscopic cholecystectomy for acute gallstone pancreatitis: is magnetic resonance cholangiopancreatography needed?

INTRODUCTION

Intraoperative cholangiography is sporadically used in patients undergoing laparoscopic cholecystectomy to delineate common bile duct anatomy and exclude retained stones. In patients with acute gallstone pancreatitis, intraoperative cholangiography may reduce the need for preoperative magnetic resonance cholangiopancreatography.

MATERIALS AND METHODS

A retrospective review of a prospectively collected patient database was undertaken over a 15-year period. The primary objective was to evaluate intraoperative assessment of the common bile duct with intraoperative cholangiography in patients with acute gallstone pancreatitis.

RESULTS

A total of 2215 patients underwent laparoscopic cholecystectomy between October 1998 and December 2013; 113 patients (of whom 77 were women) with a mean age of 54 years (range 16-88 years) were diagnosed with acute gallstone pancreatitis. Of these, 102 patients (90%) underwent laparoscopic cholecystectomy with intraoperative cholangiography, which was normal in 89 cases. Thirteen patients had choledocholithiasis on intraoperative cholangiography, 11 of whom were managed with concomitant trans-cystic duct exploration and clearance. Two patients required postoperative endoscopic retrograde cholangiopancreatography.

CONCLUSIONS

In patients diagnosed with acute gallstone pancreatitis, it is reasonable to proceed directly to surgery using intraoperative cholangiography on the same admission as the definitive assessment of the common bile duct. This negates the need for magnetic resonance cholangiopancreatography and can translate into cost savings and reduced length of stay.

The 'Drug Bag' method: lessons from anthropological studies of antibiotic use in Africa and South-East Asia

Understanding the prevalence and types of antibiotics used in a given human and/or animal population is important for informing stewardship strategies. Methods used to capture such data often rely on verbal elicitation of reported use that tend to assume shared medical terminology. Studies have shown the category 'antibiotic' does not translate well linguistically or conceptually, which limits the accuracy of these reports. This article presents a 'Drug Bag' method to study antibiotic use (ABU) in households and on farms, which involves using physical samples of all the antibiotics available within a given study site. We present the conceptual underpinnings of the method, and our experiences of using this method to produce data about antibiotic recognition, use and accessibility in the context of anthropological research in Africa and South-East Asia. We illustrate the kinds of qualitative and quantitative data the method can produce, comparing and contrasting our experiences in different settings. The Drug Bag method produce accurate antibiotic use data as well as provide a talking point for participants to discuss antibiotic experiences. We propose it can help improve our understanding of antibiotic use in peoples' everyday lives across different contexts, and our reflections add to a growing conversation around methods to study ABU beyond prescriber settings, where data gaps are currently substantial.

Clinical Obesity Services in Public Hospitals in Australia: a position statement based on expert consensus

We aimed to describe the current state of specialist obesity services for adults with clinically severe obesity in public hospitals in Australia, and to analyse the gap in resources based on expert consensus. We conducted two surveys to collect information about current and required specialist obesity services and resources using open-ended questionnaires. Organizational level data were sought from clinician expert representatives of specialist obesity services across Australia in 2017. Fifteen of 16 representatives of current services in New South Wales (n = 8), Queensland (n = 1), Victoria (n = 2), South Australia (n = 3), and the Australian Capital Territory (n = 1) provided data. The composition of services varied substantially between hospitals, and patient access to services and effective treatments were limited by strict entry criteria (e.g. body mass index 40 kg/m² or higher with specific complication/s), prolonged wait times, geographical location (major cities only) and out-of-pocket costs. Of these services, 47% had a multidisciplinary team (MDT), 53% had an exercise physiologist/physiotherapist, 53% had a bariatric surgeon and 33% had pharmacotherapy resources. Key gaps included staffing components of the MDT (psychologist, exercise physiologist/physiotherapist) and access to publicly funded weight loss pharmacotherapy and bariatric surgery. There was consensus on the need for significant improvements in staff, physical infrastructure, access to services, education/training in obesity medicine and targeted research funding. Based on the small number of existing, often under-resourced specialist obesity services that are located only in a few major cities, the vast majority of Australians with clinically severe obesity cannot access the specialist evidence based treatments needed.

Effects of posture and anatomical location on inter-recti distance measured using ultrasound imaging in parous women

STUDY DESIGN

Cross-sectional repeated measures.

OBJECTIVES

To quantify the effects of posture and measurement site on the inter-recti distance (IRD) and investigate the reliability of IRD measurement using ultrasound imaging in different postures.

BACKGROUND

The linea alba connects the rectus abdominis muscles anteriorly and the width is known as the IRD. The IRD is usually measured in crook-lying and is the primary outcome measure to assess for a divarication of recti abdominis (DRA). The effects of posture and measurement site on the IRD have not been investigated.

METHODS

Ultrasound imaging was used to measure IRD in 41 women ≥8 weeks postpartum. The IRD was measured at three sites (superior-umbilicus, umbilicus and inferior-umbilicus), in three postures (crook-lying, sitting and standing), and repeated one-week later. The effects of posture and site were investigated using one-way ANOVAs. Reliability was analysed using Intraclass correlation coefficients (ICCs), Bland Altman analyses, standard error of measurement and minimal detectable change.

RESULTS

The IRD was wider when standing vs. lying at both the superior-umbilicus and umbilicus by 0.30 cm (95% CI 0.21 to 0.39) and 0.20 cm (0.11-0.30) respectively (p < 0.001). Measurements at the inferior-umbilicus were, on average, 1.6 and 2.1 cm narrower than superior-umbilicus and umbilicus sites, respectively (p < 0.001). There was high intra-rater reliability within-session (ICC_3.3) and between-session (ICC_3.1) at all sites measured.

CONCLUSION

The IRD can be measured reliably at all sites and postures. The IRD is wider at superior-umbilicus and umbilicus when upright compared with lying. There is a difference in IRD between all sites measured.

Efficacy and safety of an oral device to reduce food intake and promote weight loss

Objective

Minimal risk weight loss tools are needed. This study's objective was to confirm Food and Drug Administration submissions of the SmartByte™ System's safety and efficacy.

Methods

This 16-week, prospective, single-arm, four-centre, observational study assessed the oral device in combination with a video-delivered lifestyle programme in adults aged 18-49 years with body mass index 27 to <35 kg m-2.

Results

Seventy-six subjects received the device and video lifestyle instruction. The prespecified per protocol (PP) population (N = 40) required sensor-verified use of the device ≥7 times per week for 14 of 16 weeks, overall device usage rate of ≥33% and study completion. At week 16, 12 (30%) achieved ≥5% weight loss, 16 (40%) achieved ≥4% and 21 (52.5%) achieved ≥3%. Week 16 mean loss for the PP population was 2.93%, and among 36 participants who did not meet PP criteria, it was 1.45%. Among 76 intent-to-treat subjects, two subjects reported three mild to moderate device-related adverse events, resolving spontaneously (one hard palate abrasion and two tongue lacerations).

Conclusion

The System, a minimal risk tool, can help individuals achieve meaningful weight loss, when used with a lifestyle video. More frequent device use was associated with more weight loss, on average, and greater chance of achieving ≥4% or ≥5% weight loss.

Test-retest reliability of the irrational performance beliefs inventory

The irrational performance beliefs inventory (iPBI) was developed to measure irrational beliefs within performance domains such as sport, academia, business, and the military. Past research indicates that the iPBI has good construct, concurrent, and predictive validity, but the test-retest reliability of the iPBI has not yet been examined. Therefore, in the present study the iPBI was administered to university sport and exercise students (n = 160) and academy soccer athletes (n = 75) at three-time points. Time point two occurred 7 days after time point one, and time point three occurred 21 days after time point two. In addition, social desirability was also measured. Repeated-measures MANCOVAs, intra-class coefficients, and Pearson's (r) correlations demonstrate that the iPBI has good test-retest reliability, with iPBI scores remaining stable across the three-time points. Pearson's correlation coefficients revealed no relationships between the iPBI and social desirability, indicating that the iPBI is not highly susceptible to response bias. The results are discussed with reference to the continued usage and development of the iPBI, and future research recommendations relating to the investigation of irrational performance beliefs are proposed.

Musculoskeletal injuries in British Army recruits: a prospective study of incidence in different Infantry Regiments

BACKGROUND

Musculoskeletal injuries and attrition incurred during basic military training are a significant socioeconomic burden across many Defence Forces. In order to plan an injury prevention strategy, the purpose of this study was to quantify the regiment-specific musculoskeletal injury patterns and training outcomes.

METHODS

This was a prospective observational study of the Parachute (n=734), Guards (n=1044), Line (n=3472) and Gurkha (n=458) Regiments of the British Army recruits during a 26-week basic military training programme over a 2-year period. The participant demographic characteristics were: age 18.9 years (SD±2.3), height 176.5 cm (SD±7.80), mass 69 kg (SD±9.7) and body mass index 22.14 kg/m² (SD±2.5).

RESULTS

The incidence of injuries (86%, 46%, 48% and 10%) was significantly different (p<0.001) as were the first time pass out rates (p=0.02) of 38%, 51%, 56% and 98% for Parachute, Guards, Line and Gurkha, respectively. Overuse injuries were more frequently reported than both acute and recurrent injuries in all regiments (X²=688.01, p<0.01).

CONCLUSIONS

The disparity in injury incidence and training outcome between Infantry Regiments suggests that the demands of training be taken into account when devising injury prevention strategies.

Health Issues in Ethnic Minorities: Awareness and Action

A key issue in health provision is the approach to health inequalities. In the UK, black and ethnic minority populations are disadvantaged in this respect. We obtained annual/public health reports from 13 health authorities (HAs) and 22 primary care trusts/groups (PCT/Gs) serving conurbations with large black and ethnic minority populations, and examined them for mention of special health issues for these groups and the action being taken. 22 of the 35 reports referred to such issues but only 17 referred to special initiatives; the most frequently mentioned were diabetes and coronary heart disease. We recommend that HAs and PCT/Gs serving large black and ethnic minority populations state specifically in their annual reports their awareness of health-equality issues and the action being taken to address them.

Candidate Genes for Nonsyndromic Cleft Palate Detected by Exome Sequencing

Nonsyndromic cleft palate only (nsCPO) is a facial malformation that has a livebirth prevalence of 1 in 2,500. Research suggests that the etiology of nsCPO is multifactorial, with a clear genetic component. To date, genome-wide association studies have identified only 1 conclusive common variant for nsCPO, that is, a missense variant in the gene grainyhead-like-3 ( GRHL3). Thus, the underlying genetic causes of nsCPO remain largely unknown. The present study aimed at identifying rare variants that might contribute to nsCPO risk, via whole-exome sequencing (WES), in multiply affected Central European nsCPO pedigrees. WES was performed in 2 affected first-degree relatives from each family. Variants shared between both individuals were analyzed for their potential deleterious nature and a low frequency in the general population. Genes carrying promising variants were annotated for 1) reported associations with facial development, 2) multiple occurrence of variants, and 3) expression in mouse embryonic palatal shelves. This strategy resulted in the identification of a set of 26 candidate genes that were resequenced in 132 independent nsCPO cases and 623 independent controls of 2 different ethnicities, using molecular inversion probes. No rare loss-of-function mutation was identified in either WES or resequencing step. However, we identified 2 or more missense variants predicted to be deleterious in each of 3 genes ( ACACB, PTPRS, MIB1) in individuals from independent families. In addition, the analyses identified a novel variant in GRHL3 in 1 patient and a variant in CREBBP in 2 siblings. Both genes underlie different syndromic forms of CPO. A plausible hypothesis is that the apparently nonsyndromic clefts in these 3 patients might represent hypomorphic forms of the respective syndromes. In summary, the present study identified rare variants that might contribute to nsCPO risk and suggests candidate genes for further investigation.

Does intentional weight loss improve daytime sleepiness? A systematic review and meta-analysis

Obesity is associated with excessive daytime sleepiness, but its causality remains unclear. We aimed to assess the extent to which intentional weight loss affects daytime sleepiness. Electronic databases were searched through 24 October 2016. Studies involving overweight or obese adults, a weight loss intervention and repeated valid measures of daytime sleepiness were included in the review. Two independent reviewers extracted data on study characteristics, main outcome (change in daytime sleepiness score standardized by standard deviation of baseline sleepiness scores), potential mediators (e.g. amount of weight loss and change in apnoea-hypopnoea index) and other co-factors (e.g. baseline demographics). Forty-two studies were included in the review. Fifteen before-and-after studies on surgical weight loss interventions showed large improvements in daytime sleepiness, with a standardized effect size of -0.97 (95% confidence interval [CI] -1.21 to -0.72). Twenty-seven studies on non-surgical weight loss interventions showed small-to-moderate improvement in daytime sleepiness, with a standardized effect size of -0.40 (95%CI -0.52 to -0.27), with no difference between controlled and before-and-after studies. We found a nonlinear association between amount of weight loss and change in daytime sleepiness. This review suggests that weight loss interventions improve daytime sleepiness, with a clear dose-response relationship. This supports the previously hypothesized causal effect of obesity on daytime sleepiness. It is important to assess and manage daytime sleepiness in obese patients.
