The future of public health doctoral education in Africa: transforming higher education institutions to enhance research and practice

The African Union and the Africa Centers for Disease Control and Prevention issued a Call to Action in 2022 for Africa's New Public Health Order that underscored the need for increased capacity in the public health workforce. Additional domestic and global investments in public health workforce development are central to achieving the aspirations of Agenda 2063 of the African Union, which aims to build and accelerate the implementation of continental frameworks for equitable, people-centred growth and development. Recognising the crucial role of higher education and research, we assessed the capabilities of public health doctoral training in schools and programmes of public health in Africa across three conceptual components: instructional, institutional, and external. Six inter-related and actionable recommendations were derived to advance doctoral training, research, and practice capacity within and between universities. These can be achieved through equitable partnerships between universities, research centres, and national, regional, and global public health institutions.

Efficacy and safety of antiparasitic therapy for neurocysticercosis in rural Tanzania: a prospective cohort study

PURPOSE

Neurocysticercosis is common in regions endemic for Taenia solium. Active-stage neurocysticercosis can be treated with antiparasitic medication, but so far no study on efficacy and safety has been conducted in Africa.

METHODS

We conducted a prospective cohort study on treatment of neurocysticercosis in Tanzania between August 2018 and January 2022. Patients were initially treated with albendazole (15 mg/kg/d) for 10 days and followed up for 6 months. Additionally in July 2021, all participants who then still had cysts were offered a combination therapy consisting of albendazole (15 mg/kg/d) and praziquantel (50 mg/kg/d). Antiparasitic treatment was accompanied by corticosteroid medication and anti-seizure medication if the patient had experienced epileptic seizures before treatment.

RESULTS

Sixty-three patients were recruited for this study, of whom 17 had a complete follow-up after albendazole monotherapy. These patients had a total of 138 cysts at baseline, of which 58 (42%) had disappeared or calcified by the end of follow-up. The median cyst reduction was 40% (interquartile range 11-63%). Frequency of epileptic seizures reduced considerably (p < 0.001). Three patients had all active cysts resolved or calcified and of the remaining 14, eight received the combination therapy which resolved 63 of 66 cysts (95%). Adverse events were infrequent and mild to moderate during both treatment cycles.

CONCLUSION

Cyst resolution was unsatisfactory with albendazole monotherapy but was very high when it was followed by a combination of albendazole and praziquantel.

The attitude-behaviour gap in biosecurity: Applying social theories to understand the relationships between commercial chicken farmers' attitudes and behaviours

Introduction

Traditionally, it is believed that people's behaviours align with their attitudes; however, during COVID-19 pandemic, an attitude-behaviour gap in relation to preventive measures has been observed in recent studies. As such, the mixed-methods research was used to examine the relationships between farmers' biosecurity attitudes and behaviours in Taiwan's chicken industry based on the cognitive consistency theory.

Methods

Content analysis of face-to-face interviews with 15 commercial chicken farmers identified their biosecurity responses to infectious disease threats.

Results

The results indicated the mismatch of farmers' attitudes and behaviours towards specific biosecurity measures, in that they act differently than they think. The findings of the qualitative research allowed the research team to conduct the subsequent quantitative, confirmatory assessment to investigate the mismatch of farmers' attitudes and behaviours in 303 commercial broiler farmers. Survey data were analyzed to discover the relationships between farmers' attitudes and behaviours in relation to 29 biosecurity measures. The results show a mixed picture. The percentage of the farmers who had the attitude-behaviour gap towards 29 biosecurity measures ranged from 13.9 to 58.7%. Additionally, at the 5% significant level, there is an association between farmers' attitudes and behaviours for 12 biosecurity measures. In contrast, a significant association does not exist for the other 17 biosecurity measures. Specifically, out of the 17 biosecurity measures, the disconnection of farmers' attitudes and behaviours was observed in three specific biosecurity measures such as using a carcass storage area.

Discussion

Based on a fairly large sample of farmers in Taiwan, this study confirms the existence of an attitude-behaviour gap in context and applies social theories to provide an in-depth understanding of how infectious diseases are managed in the animal health context. As the results demonstrate the necessity of tailoring biosecurity strategies to address the gap, it is time to reconsider the current approach by understanding farmers' real attitudes and behaviours in relation to biosecurity for the success of animal disease prevention and control at the farm level.

How Do Veterinary Students Engage When Using Creative Methods to Critically Reflect on Experience? A Qualitative Analysis of Assessed Reflective Work

Critical reflection-the exploration and questioning of one's experience, beliefs, assumptions, and actions-supports resilience, empathy, the management of uncertainty, and professional identity formation. Yet for many students and educators, the techniques to engage in critical reflection are elusive. Creative methods that foster engagement with emotional and uncertain aspects of experience reportedly help some students to reflect at a more critical level than when they use reflective writing, and this study explores more deeply the experiences of such students, who used creative methods to critically reflect on challenging or troubling past events. A narrative methodology was utilized, in which researchers collaboratively co-constructed an understanding of students' experiences of reflection to identify the activities and steps they used. Creative methods did not inherently lead to critical reflection, but when this was achieved, the creative approaches seemed to facilitate a staging of reflection, which incorporated five sequential stages: preplanning creative depiction, experimenting with different ideas, deliberately completing the reflective piece, reflecting on creative work, and reflecting again on learning and development. This cyclic, repeated revisit to experience, as students engaged in each stage of their work, appeared to facilitate both a deep connection with the emotional elements of experience and a more distanced analysis. This ultimately led to a deepening of understanding of events, including the construction of students' own beliefs and empathy with others' views.

Determinants of farmers' biosecurity mindset: A social-ecological model using systems thinking

Commercial poultry is often farmed in high-density facilities, therefore, predisposing exposure to threats of infectious diseases. Studies suggest that it is likely that farmers have little motivation to practise on-farm biosecurity. In Taiwan, where high-density intensive poultry production is commonplace, unfortunately, several avian influenza outbreaks have occurred over the past decade despite the establishment of biosecurity procedures. To develop effective interventions, it is essential to understand the determinants of farmers' biosecurity mindset through systems thinking. In this qualitative study, we directly explored the opinions of Taiwan's chicken farmers, and a grounded theory analysis was performed. The study revealed that farmers allocate resources based on their justification for the optimisation of resource utilisation, and biosecurity is the most concerning challenge. Farmers focus on the economic aspects of their production systems, particularly when the implementation of biosecurity increases production costs, and there are multifaceted, complex barriers to implementing on-farm biosecurity. Although the participant farmers accepted to take major responsibility for disease management, paradoxically, some farmers blamed the practicality of government regulations and government employees' attitudes. Additionally, the farmers rejected the government's intentions to ask farmers to take major responsibility for the outbreaks of avian influenza while some of them intended to ignore the perceived risks. Government interventions that were considered not directly related to biosecurity also negatively influenced farmers' willingness to improve biosecurity. Using the interview results together with information in the scientific literature, we constructed a modified six-level social-ecological model to explain the complex influences of macro socio-economic conditions on farmers' biosecurity mindset. The novelty of this research lies in its wider relevance to Taiwan's chicken production industry in that it provides first-hand evidence-based knowledge to demonstrate a wide number of determinants of farmers' biosecurity mindset. This social-ecological model highlights the importance of systems thinking for the development of behavioural interventions and allows adaptation to the local context. The findings of this study have relevance to Taiwan's chicken production industry and potentially to similar systems in other countries in the wider region and should result in more effective animal health management at the farm level.

Evaluation of prognostic risk models for postoperative pulmonary complications in adult patients undergoing major abdominal surgery: a systematic review and international external validation cohort study

BACKGROUND

Stratifying risk of postoperative pulmonary complications after major abdominal surgery allows clinicians to modify risk through targeted interventions and enhanced monitoring. In this study, we aimed to identify and validate prognostic models against a new consensus definition of postoperative pulmonary complications.

METHODS

We did a systematic review and international external validation cohort study. The systematic review was done in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. We searched MEDLINE and Embase on March 1, 2020, for articles published in English that reported on risk prediction models for postoperative pulmonary complications following abdominal surgery. External validation of existing models was done within a prospective international cohort study of adult patients (≥18 years) undergoing major abdominal surgery. Data were collected between Jan 1, 2019, and April 30, 2019, in the UK, Ireland, and Australia. Discriminative ability and prognostic accuracy summary statistics were compared between models for the 30-day postoperative pulmonary complication rate as defined by the Standardised Endpoints in Perioperative Medicine Core Outcome Measures in Perioperative and Anaesthetic Care (StEP-COMPAC). Model performance was compared using the area under the receiver operating characteristic curve (AUROCC).

FINDINGS

In total, we identified 2903 records from our literature search; of which, 2514 (86·6%) unique records were screened, 121 (4·8%) of 2514 full texts were assessed for eligibility, and 29 unique prognostic models were identified. Nine (31·0%) of 29 models had score development reported only, 19 (65·5%) had undergone internal validation, and only four (13·8%) had been externally validated. Data to validate six eligible models were collected in the international external validation cohort study. Data from 11 591 patients were available, with an overall postoperative pulmonary complication rate of 7·8% (n=903). None of the six models showed good discrimination (defined as AUROCC ≥0·70) for identifying postoperative pulmonary complications, with the Assess Respiratory Risk in Surgical Patients in Catalonia score showing the best discrimination (AUROCC 0·700 [95% CI 0·683-0·717]).

INTERPRETATION

In the pre-COVID-19 pandemic data, variability in the risk of pulmonary complications (StEP-COMPAC definition) following major abdominal surgery was poorly described by existing prognostication tools. To improve surgical safety during the COVID-19 pandemic recovery and beyond, novel risk stratification tools are required.

Exploring the Impacts of an Art and Narrative Therapy Program on Participants' Grief and Bereavement Experiences

Grief and bereavement impact nearly every individual at some point of their lives, often having short or long-term physical and psychosocial impacts. Yet, these issues are rarely the focus of discussion, intensive therapy programs, or policy initiatives (Corr, 2002; Doka, 2002). This research explores the impacts of a closed group art and narrative therapy program in Ontario for individuals experiencing a grief or bereavement process following the loss of a loved one. It explores the grief experiences of art therapy participants during their time in the program, the nature, extent, and impacts of social and community connections that were made, how the program influenced grief over time, and the overall effectiveness of the program. This study suggests that art and narrative therapy hold great therapeutic potential as a tool to help individuals going through a grief or bereavement process.

Carotid Intima Media Thickness and Comorbid Cardiometabolic Dysfunction in Women: The SWAN Study

Metabolic syndrome (MetS) and obesity are risk factors for atherosclerosis but their combined impact is unknown. The aim of this study was to quantify the added risk of obesity on carotid artery intima media thickness (cIMT), an early indicator for atherosclerosis, beyond MetS alone. The Study of Women’s Health Across the Nation (SWAN) is a multi-center, multi-ethnic cohort of women traversing the midlife into early late adulthood. cIMT was assessed between 2005-2007 and MetS, obesity and covariates were measured at the same time. This cross-sectional analysis is restricted to 1,433 women with a body mass index ≥18.5 kg/m2 and free of cardiovascular disease (CVD) when cIMT was measured. Mean maximum cIMT was related to obesity, MetS and their interaction using multivariable linear regression models. The average age was 60 years (standard deviation 2.7) and the prevalence of obesity and MetS were 44% and 35%, respectively. Both conditions occurred in 24% of women. After adjustment for age, race, smoking, family history of heart disease, and antilipemic medications, obese women had a 0.051mm (95% confidence interval (CI): 0.033,0.070; p<0.001) larger maximum cIMT versus women not obese and women with MetS had a 0.066mm (95%CI: 0.042,0.090; p<0.001) larger maximum cIMT versus women without MetS. There was a statistically significant antagonistic interaction between obesity and MetS; women with both had a mean cIMT of 0.972mm (95%CI: 0.955,0.989) and MetS alone a cIMT of 0.961mm (95%CI:0.938,0.983). This suggests that there is only a small risk of obesity on augmenting cIMT beyond MetS alone.

Children, Fetuses, and the Non-Existent: Moral Obligations and the Beginning of Life

The morality of abortion is a longstanding controversy. One may wonder whether it is even possible to make significant progress on an issue over which so much ink has already been spilled and there is such polarizing disagreement (Boyle, 1994, The Journal of Medicine and Philosophy 19:183–200). The papers in this issue show that this progress is possible—there is more to be said about abortion and other crucial beginning-of-life issues. They do so largely by applying contemporary philosophical tools to moral questions involving life’s beginning. The first two papers defend the pro-life view from recent objections involving miscarriage and abortion doctors. The third shows how the social model of disability and the concept of transformative experience apply to classic debates like abortion and euthanasia. The final two papers address how rights and harms apply to children and to beings that do not yet exist. All five papers make a noteworthy contribution to the moral issues that arise at the beginning of life.

The experience of D/deaf healthcare professionals during the coronavirus pandemic

Background

The coronavirus pandemic, in particular the introduction of masks, presented a huge challenge for the UK’s D/deaf community, many of whom rely on visual cues in lipreading and sign language. This particularly affected D/deaf healthcare professionals (HCPs), who faced significant communication challenges at work due to the lack of transparent masks or other reasonable adjustments.

Aims

To determine the impact that a lack of transparent masks and reasonable adjustments had on communication, confidence at work and well-being among D/deaf HCPs during the coronavirus pandemic.

Methods

A survey was sent to all members of the ‘UK Deaf Healthcare Professionals Group’ on Facebook, the ‘Healthcare Professionals with Hearing Loss’ listserver and promoted on Social Media.

Results

Eighty-three responses were received. Nine (11%) individuals had access to transparent masks. Over three-quarters of respondents reported feeling anxious and fearful of making a mistake due to communication difficulties. Fourteen (17%) were removed from clinical roles due to a lack of reasonable adjustments. One-third felt they would need to consider an alternative career if improvements were not made. Seventy-eight per cent felt the communication needs of D/deaf HCPs had not been met during the pandemic.

Conclusions

D/deaf HCPs felt left behind, isolated and frustrated by a lack of transparent masks and reasonable adjustments to meet their communication needs. Loss of experienced, qualified HCPs has a significant economic and workforce impact, particularly during a pandemic. Urgent action is needed to ensure D/deaf HCPs are provided with the workplace support required under the Equality Act (2010).

Safety and efficacy of teriparatide treatment for severe osteoporosis in patients with Duchenne muscular dystrophy

Osteoporosis is a major concern in patients with Duchenne muscular dystrophy. In this novel study of teriparatide treatment in 6 patients with severe osteoporosis, bone health (fractures, vertebral morphometry, and DXA) remained stable, with no adverse events. These findings will help inform future osteoporosis research in this challenging population.

INTRODUCTION

Despite standard therapy with vitamin D and bisphosphonates (BP), many patients with Duchenne muscular dystrophy (DMD) continue to sustain fragility fractures due to long-term glucocorticoid treatment and limited mobility. We aimed to evaluate the safety and efficacy of teriparatide for the treatment of severe osteoporosis in adolescent and young adult patients with DMD.

METHODS

We prospectively treated 6 patients with DMD who had severe osteoporosis with teriparatide 20 mcg subcutaneously daily for 1-2 years. Inclusion criteria were long-term glucocorticoid therapy, and severe osteoporosis despite treatment with BP, or intolerance to BP. We examined long bone and vertebral fracture outcomes, including vertebral morphometry measures, bone mineral density and content, bone formation markers, safety indices, and adverse events.

RESULTS

The mean age at teriparatide start was 17.9 years (range 13.9-22.1 years). All 6 patients were on daily glucocorticoids (mean ± SD; duration 10.9 ± 2.5 years) and 5 were non-ambulatory. Five patients had been treated with BP for 7.9 ± 4.2 years. All had vertebral and a history of long bone fragility fractures at baseline. Vertebral heights and Genant fracture grading remained stable. Long bone fracture rate appeared to decrease (from 0.84/year to 0.09/year); one patient sustained a long bone fracture at 6 months of treatment. Trajectories for change in bone mineral density and content were not different post- vs. pre-teriparatide. Procollagen type 1 amino-terminal propeptide (P1NP) increased, while laboratory safety indices remained stable and non-concerning. No adverse events were observed.

CONCLUSION

In six patients with DMD treated with teriparatide for severe osteoporosis, we observed stable bone health and modest increases in P1NP, without safety concerns. Further studies are needed to better understand teriparatide efficacy for treatment of osteoporosis in patients with DMD.

Pain management for medical and surgical termination of pregnancy between 13 and 24 weeks of gestation: a systematic review

Background

High‐quality care for termination of pregnancy (TOP) requires pain to be effectively managed; however, practices differ, and the available guidelines do not specify optimal strategies.

Objective

To guide providers in effective pain management for second‐trimester medical and surgical TOP.

Search strategy

We searched PubMed, Cochrane and Embase databases, and the US National Library of Medicine clinical trials registry, from inception to the end of June 2019, and hand‐searched reference lists.

Selection criteria

Trials comparing pain management strategies with no treatment, placebo or active interventions during induced medical or surgical TOP, occurring between 13 and 24 weeks of gestation, and reporting direct or indirect measures of pain.

Data collection and analysis

Both authors summarised and systematically assessed the evidence and risk of bias using standard tools.

Main results

We included seven medical and four surgical TOP studies, with 453 and 349 participants, respectively. The heterogeneity of interventions and outcomes prevented pooled analyses. Medical TOP: women receiving routine or continuous epidural analgesia experienced mild pain. The prophylactic use of nonsteroidal anti‐inflammatory drugs (NSAIDs) decreased pain (mean difference −0.5, P < 0.001) and additional opioid requirements (3.5 versus 7 mg, P = 0.04) compared with placebo/other treatment. Paracervical block was ineffective. No studies assessed intramuscular (IM)/intravenous (IV) opioid or nonpharmacological treatment. Surgical TOP: general anaesthesia/deep IV sedation alleviated pain. Nitrous oxide was ineffective. No studies assessed moderate IV sedation, IV/IM opioid, paracervical block without sedation, NSAID or nonpharmacological treatment.

Conclusion

Based on limited data, regional analgesia and NSAIDs mitigated second‐trimester medical TOP pain; general anaesthesia/deep IV sedation alleviated surgical TOP pain.

Tweetable abstract

Although women experience intense pain during second‐trimester termination of pregnancy, few data are available to inform their treatment.

Prevalence of eating disorder is lower in migrants than in the Australian-born population

OBJECTIVES

There are limited data on the epidemiology of eating disorders (ED) in migrants. Recent Scandinavian research suggests that migrants are at lower risk of eating disorders, however, to our knowledge there have not been comparable studies exploring eating disorders in Australian adult populations. We sought to explore the prevalence of EDs in first-generation migrants to Australia in comparison with the Australian-born population. A secondary aim was to explore ED prevalence across first-generation migrants from different regions of birth (Europe, Asia, Africa, and Other).

METHODS

We conducted sequential cross-sectional population surveys in South Australian individuals aged over 15 years in 2015 and 2016 (n = 6052). Demographic data were collected and migration status was inferred based on a country of birth outside Australia. Questions asked regarding disordered eating were based on the Eating Disorders Examination.

FINDINGS

The 3-month prevalence of any ED was found to be significantly lower in first-generation migrants born outside Australia (4.5%, 95% CI 3.6-5.6) in comparison to the Australian-born population (6.4%, 95% CI 5.7-7.2). People born in countries in Africa (11.0% 95% CI 6.1-19.1) had a significantly higher prevalence of EDs than those born in Asia (4.0% 95% CI 2.7-5.8).

CONCLUSIONS

First-generation migrants to Australia may be at lower risk of eating disorders compared to their Australia-born peers, suggesting support for a 'healthy immigrant effect'.

Effects of an adapted story grammar intervention on the listening comprehension of children with autism

Children with autism spectrum disorder (ASD) often develop the word reading skills necessary to read text but struggle with reading comprehension. Comprehension skills are often under addressed in early elementary settings leaving children with ASD at a disadvantage once they are expected to read for meaning. This study investigated the impact of an adapted story grammar intervention on the listening comprehension of five children with ASD in kindergarten through second grade. The intervention embedded evidence-based practices shown to support the learning of children with ASD during story grammar instruction. All participating children demonstrated increased correct responding to fact and inference questions following intervention. Data suggest that all participants required visuals to participate in and learn from the intervention. Social validity data indicate the classroom teacher perceived the intervention as helpful and feasible. Implications for instruction and future research are discussed.

National assessment of availability, awareness, and utilization of supervised exercise therapy for peripheral artery disease patients with intermittent claudication

BACKGROUND

Supervised exercise therapy (SET) is an inexpensive, low-risk, and effective option when compared with invasive therapies for the treatment of patients with peripheral artery disease (PAD) and intermittent claudication. Randomized, controlled trials have demonstrated the benefits of SET in improving maximum walking distance in intermittent claudication patients, and society guidelines recommend SET as first-line therapy. In 2017, the Centers for Medicare & Medicaid Services (CMS) added coverage of SET. We aimed to evaluate the availability and use of SET programs, determine the awareness of SET CMS coverage in the United States, and gauge the academic interest in SET in the vascular community.

METHODS

An eight-question online survey regarding SET coverage, reimbursement, barriers to prescription, and SET use was sent to 900 vascular surgeons, cardiologists, and vascular medicine physicians across the United States. The most recent 2-year programs for the Vascular Annual Meeting, Midwestern Vascular Society, Eastern Vascular Society, and Western Vascular Society were reviewed to identify SET-related abstracts and gauge academic interest and awareness for SET within the vascular surgery community.

RESULTS

We received 135 physician responses (15%) to the survey. All 50 states were represented. The majority of responders (54%) stated that there was no SET program at their facility, and 5% did not know if there was a SET program available. Of those who did have a SET program available, 81% were associated with cardiac rehabilitation and 19% had a PAD-specific program. A significant number of physicians (49%) had never referred a patient for SET. Twenty-six percent were not aware that CMS covered SET sessions. Of the physicians who were aware of CMS reimbursement, 36% had never referred a patient to a SET program. Of all surveyed, 98% indicated they would refer patients to a SET program if one was available. Top barriers to use of a SET program included (1) no SET center availability and (2) significant cost or travel expense to the patient. A review of major vascular surgery meeting programs for the last 2 years yielded no identification of a SET-related abstract.

CONCLUSIONS

There is a lack of both availability and use of SET for patients with PAD with claudication, despite guideline recommendations and CMS reimbursement for SET sessions in the United States. When SET is offered, it is typically through cardiac rehabilitation programs which is not focused on PAD. Travel distance, lack of SET program availability, and low reimbursement rates are primary areas that could be addressed to improve use.

Patient perspectives on medication self-management in rural Kenya: a cross-sectional survey

OBJECTIVES

The presence of HIV, tuberculosis and non-communicable diseases result in a double burden of disease in the East African community. Most studies have focused on urban Nairobi and western Kenya, leading to a lack of information on rural regions that make up 75% of the population. This study determined baseline rates and barriers to medication self-management in rural Meru County.

DESIGN

A cross-sectional, descriptive community survey focused on Meru, Kenya.

SETTING

Participants were surveyed at a local Kithoka dispensary and the government operated Meru Level 5 Hospital.

PARTICIPANTS

Seventy-five chronic illness patients between June 2016 and July 2016.

INTERVENTION

Twelve-question Measures of Drug Self-Management Scale (MeDS).

MAIN OUTCOME MEASURE

Baseline rates of medication self-management. A score of 10 or more defined 'adequate' medication drug self-management.

RESULTS

The average MeDS score was 8.16 ± 2.4, indicating inadequate medication self-management. There was no significant difference across age (P = 0.75), and between the scores of males and females (8.1 ± 2.4 and 8.2 ± 2.5, respectively, P = 0.89). Minor side effects and the idea that taking medicines disrupt life were highly associated with inadequate drug self-management (r = 0.58). Forgetfulness and non-adherence had the highest correlation (r = 0.64). Cost is a large barrier, with 64% agreeing that they have a hard time paying for their medicines.

CONCLUSIONS

All questions on the MeDS survey had statistically significant correlations with the overall score, while gender and age did not. The MeDS questionnaire showed to be an effective tool to evaluate risk of long-term non-adherence globally in rural populations.

P6206Death, debility, and destitution following recurrent myocardial infarction in older adults

Background

Most prior research on outcomes among older adults with established cardiovascular diseases focuses on recurrent events and hospitalizations. However, older adults value financial security and functional independence in addition to these disease-focused metrics. Recurrent cardiovascular events may increase risk of long-term nursing home residence and financial strain.

Purpose

To compare the risk for death, debility (long-term residence in a nursing home), and destitution (eligibility for health insurance programs for impoverished individuals) among older adults with recurrent myocardial infarction (MI) and controls.

Methods

We conducted a retrospective cohort study using administrative data from the United States Medicare program, a health insurance program for older adults. Among all patients who experienced a first overnight hospitalization with a discharge diagnosis of MI between 1 January 2007 and 30 June 2016, we identified patients with a recurrent MI hospitalization. Additionally, we selected controls from the same population of patients with MI, matched on calendar year of the initial MI and days since the initial MI. We included 194,481 patients aged 66 years and older with recurrent MI hospitalizations and 777,924 controls. Patients were followed for death, debility, and destitution until 31 December 2016. We used Kaplan-Meier curves and Cox proportional hazards models adjusted for sociodemographic factors, comorbidities, and healthcare utilization to compare patients with recurrent MI and matched controls.

Results

The average age of the population was 80.0 (standard deviation 8.3) years and 56.7% were women. Patients with recurrent MI were more likely to have a history of diabetes, chronic kidney disease, heart failure and peripheral artery disease than controls. The cumulative incidence of death, debility, and destitution were all higher among patients with recurrent MI than their matched controls (Figure). Comparing patients with recurrent MI to controls, the hazard ratios (95% confidence intervals) were 2.11 (2.09–2.13) for death, 0.92 (0.89–0.94) for debility, and 1.34 (1.29–1.39) for destitution after multivariable adjustment.

Death, debility, and destitution

Conclusion

Preventing recurrent MIs has the potential to reduce not only mortality but also destitution.

Health care engagement behaviors of men who use performance- and image-enhancing drugs in Australia

Background: Although people who inject performance- and image-enhancing drugs (PIEDs) report fewer unsafe injecting practices, stigma and discrimination may negatively impact their access to help and information. Engagement with health care services, compared with social networks (friends, relatives, and gym associates) and the Internet and media (steroid user forums, information sites, and magazines), may be important for harm minimization. Methods: A cross-sectional Internet or in-person survey of men who use PIEDs in Australia in 2014-2015 examined differences in sources for PIEDs, injecting equipment, and anabolic-androgenic steroids (AAS) information and factors associated with having periodical medical checks related to PIEDs issues using multivariate logistic regression. Results: In total, 267 men (mean age: 25 years, SD: 8.7 years; 246 of 267 [92%] reported recent AAS injection) were recruited. Most participants sourced injecting equipment from health professionals, PIEDs from their social networks, and AAS information from the Internet and media. Self-reported AAS knowledge was high and frequent. Higher income (adjusted odds ratio [AOR]: 2.04, 95% confidence interval [CI]: 1.03, 4.00), ≥2 different PIEDs used in addition to AAS (AOR: 1.94, 95% CI: 1.08, 3.49), and sourcing AAS information from health care professionals (AOR: 3.14, 95% CI: 1.81, 5.46) were independently associated with periodical medical checks. Participants nominated preference for improved health services through needle-syringe programs, primary care services, and peer educator support groups. Conclusion: Men who use PIEDs in Australia consider themselves well informed but tend to use Internet and media sources, providing potentially misleading or inaccurate information. Increasing trust between men who use PIEDs and health care providers may enable delivery of PIEDs-specific information to those at greatest need.

C-50 Influence of Childhood Maltreatment on Decision-Making in Adolescents

Objective

Decision-making requires weighing potential gains and losses. Adolescents who have experienced maltreatment may be more sensitive to potential gains or losses than other adolescents. The aim of these analyses was to examine trajectories of decision-making over time in adolescents based on maltreatment history and severity.

Method

The study included 69 adolescents 13 to 17 years old (M = 14.9). Maltreatment history and severity were assessed using the Childhood Trauma Questionnaire. Adolescents also completed a modified Iowa Gambling Task (mIGT). Outcomes of interest were the percentage of advantageous responses and net score (measure of overall performance integrating advantageous and disadvantageous plays) for each of three blocks.

Results

The trajectory of performance across blocks was defined using a conditional linear growth curve model with factor loadings fixed at block 1, block 2, and block 3. Greater maltreatment severity was associated with less increase in net score over time (M = -4.453, p < .001). In contrast, abuse severity (M = 6.675, p = .002) and the presence of neglect (M = 13.058, p = .002) were associated with sharper increases in net score. A regression revealed maltreatment severity, presence of abuse, presence of neglect, and abuse severity significantly predicted the percentage of advantageous plays only during the second block of the mIGT (R2 = .180, p = .030).

Conclusions

This study provides evidence that maltreatment history and severity are associated with the trajectory of decision-making over time. It also provides support for the importance of examining performance trajectory and heterogeneity in maltreatment regarding cognitive processing.

Bio-derived hydroxystearic acid ameliorates skin age spots and conspicuous pores

INTRODUCTION

We report on the preparation and efficacy of 10-hydroxystearic acid (HSA) that improves facial age spots and conspicuous pores.

METHODS

The hydration of oleic acid into HSA was catalyzed by the oleate hydratase from Escherichia coli. Following treatment with HSA, collagen type I and type III was assessed in primary human dermal fibroblasts together with collagen type III, p53 protein levels and sunburn cells (SBC) after UVB irradiation (1 J cm^-2 ) by immunohistochemistry on human ex vivo skin. UVB-induced expression of matrix metalloprotease-1 (MMP-1) was determined from full thickness skin by RT-qPCR. Modification of the fibroblast secretome by HSA was studied by mass-spectrometry-based proteomics. In a full-face, double blind, vehicle-controlled trial HSA was assessed for its effects on conspicuous facial pore size and degree of pigmentation of age spots in Caucasian women over an 8-week period.

RESULTS

HSA was obtained in enantiomeric pure, high yield (≥80%). Collagen type I and type III levels were dose-dependently increased (96% and 244%; P < 0.01) in vitro and collagen type III in ex vivo skin by +57% (P < 0.01) by HSA. HSA also inhibited UVB-induced MMP-1 gene expression (83%; P < 0.01) and mitigated SBC induction (-34% vs. vehicle control) and reduced significantly UV-induced p53 up-regulation (-46% vs. vehicle control; P < 0.01) in irradiated skin. HSA modified the fibroblast secretome with significant increases in proteins associated with the WNT pathway that could reduce melanogenesis and proteins that could modify dermal fibroblast activity and keratinocyte differentiation to account for the alleviation of conspicuous pores. Docking studies in silico and EC50 determination in reporter gene assays (EC50 5.5 × 10^-6  M) identified HSA as a peroxisomal proliferator activated receptor-α (PPARα) agonist. Clinically, HSA showed a statistically significant decrease of surface and volume of skin pores (P < 0.05) after 8 weeks of application and age spots became significantly less pigmented than the surrounding skin (contrast, P < 0.05) after 4 weeks.

CONCLUSION

HSA acts as a PPARα agonist to reduce the signs of age spots and conspicuous pores by significantly modulating the expression of p53, SBC, MMP-1 and collagen together with major changes in secreted proteins that modify keratinocyte, melanocyte and fibroblast cell behavior.

Association between urodynamic parameters and urine neutrophil gelatinase-associated lipocalin concentrations in children with neuropathic bladders

BACKGROUND

Neutrophil gelatinase-associated lipocalin (NGAL) is a marker of acute kidney injury, and has been shown to be a sensitive marker of renal damage in urinary tract obstruction. Children with neurogenic bladders are at risk of renal damage as a result of increased pressure within the urinary system. A marker of upper tract deterioration in this population would be useful to guide management.

OBJECTIVE

The aim of the study is to compare urinary NGAL (uNGAL) concentrations between children who have elevated and normal detrusor pressure and between those with low and normal compliance, on urodynamics.

STUDY DESIGN

This is a cross-sectional study of children with neurogenic bladder who underwent routine urodynamics from August 2015 to March 2016. Patients with positive urine cultures from the time of urodynamics were excluded from analysis. Urine was obtained from the time of urodynamics for uNGAL measurement. Urodynamics were reviewed. High pressure is defined as a detrusor pressure of 40 cm of water or greater at the volume where catheterization is normally performed. Compliance was calculated at the volume where catheterization is performed.

RESULTS

A total of 89 patients were included (low pressure, n = 73; high pressure, n = 16 and low compliance, n = 41; normal compliance, n = 40). Median uNGAL concentrations were not different between patients with low and high pressure, but there was a higher median uNGAL concentration in patients with normal compliance compared with those with low compliance. There was no correlation between maximum detrusor pressure and uNGAL concentration, but there was a moderate relationship between compliance and uNGAL concentration (r_s = 0.43, p < 0.01 for non-normalized uNGAL and r_s = 0.30, p < 0.01 for normalized uNGAL).

DISCUSSION AND CONCLUSION

There is an increase in uNGAL concentrations in patients with normal compliance compared with those with low compliance, but no difference between patients with low or high pressure.

A systematic review of qualitative studies of adults' experiences of being assessed for psychological therapies

Objective

To synthesize the qualitative literature on adults’ experiences of psychological therapy assessments. The review was led by people with experience of undergoing assessments, with high levels of client involvement throughout.

Search strategy

A comprehensive search of electronic databases was undertaken, with additional search strategies employed to locate further literature.

Inclusion criteria

Studies were included that qualitatively explored the experiences of people aged 16+ who had been assessed for psychological therapy services. Assessments could be structured or unstructured. Qualitative was defined as any analysed account of people's experiences, including qualitative survey data.

Data extraction and synthesis

Literature quality was appraised using the Critical Appraisal Skills Program checklist, modified to include client involvement and intersectionalities. Following data extraction, thematic synthesis was used to synthesize findings across studies.

Results

Of 12 743 titles were screened, with 13 studies relevant to the review. Themes and subthemes were identified at three stages of the assessment process: the journey to the assessment, at the assessment, and after the assessment. Findings highlighted the emotional impact of assessments, collaboration, intersectionalities, rights, pathologization, socioeconomic restrictions, and information and support needs. Implications and limitations were indicated.

Discussion and conclusions

Findings were situated within the trauma‐informed (TIA) literature. Trauma‐informed assessment principles, including collaborative assessments, may be fruitful means of improving people's experiences. Whilst the benefits of collaboration appear self‐evident, explicitly collaborative approaches were not the norm, nor were studies conducted independently. Further service user research is needed. A greater understanding of the experience of minority groups is also needed.

The Impact Of Structured Exercise Programs On Metabolic Syndrome And Its Components: A Systematic Review

BACKGROUND

The metabolic syndrome (MetS) is highly prevalent and associated with higher risk of diabetes and cardiovascular events. Exercise programs have been shown to improve components of MetS, but the optimal design of a structured exercise program for treatment of the MetS remains unclear.

PURPOSE

To assess the impact of different exercise programs on the MetS and its components.

METHODS

MEDLINE via PubMed and Embase was searched. Randomized controlled trials of supervised exercise alone and in combination with nutrition programs compared with usual care in adults with the MetS were selected. Two authors independently reviewed articles to select eligible studies and performed data abstraction. Eight studies representing 1218 patients were included. The participants had a median age of 51, median BMI of 29 kg/m², and were 55% male. Mean weight loss increased with program duration. For combination programs, the mean weight loss was -2.6 kg, -3.7 kg, and -6.5 kg for 3, 6, and 12 months, respectively. The components of the MetS most frequently statistically significantly improved were waist circumference (6/6 studies), blood pressure (4/6 studies), and high-density lipoprotein cholesterol (3/6 studies).

LIMITATIONS

Studies did not include long-term follow-up post program completion to evaluate persistence of benefit. It is unknown whether the same results would be found in an older, more obese population.

CONCLUSION

Supervised exercise programs yield significant resolution of components of the MetS, particularly in reducing waist circumference. Longer program duration and frequent interval sessions appear to have highest benefit and thus may help reduce cardiovascular risk and diabetes associated with the MetS.

Variation among subspecialists in the diagnosis of urinary tract infection in children with neurogenic bladders

BACKGROUND

Children with neurogenic bladders who require clean intermittent catheterization (CIC) frequently have bacteriuria. However, there is no consensus on what constitutes at urinary tract infection (UTI) in this population. Multiple subspecialists are often involved in the management of these patients, although they are frequently cared for by hospitalists when admission is required.

OBJECTIVE

The objective of this study was to describe the variability in opinion between subspecialists in the diagnosis of a UTI in CIC-dependent children.

STUDY DESIGN

A scenario-based survey was distributed to physicians in the divisions of urology, nephrology, and hospital medicine at a single free-standing children's hospital. Respondents rated their degree of confidence on whether a specific scenario represented UTI or colonization on an 11-point Likert Scale. Median responses were compared with the Kruskal-Wallis test with pair-wise comparisons.

RESULTS

Back/flank pain, abdominal pain, and vomiting were the most common symptoms that were suggestive of a UTI in a non-febrile child. There was no single symptom chosen that was the most suggestive of a UTI in CIC-dependent child. There was significant variability between specialists in the diagnosis of UTI in specific clinical scenarios on the survey. Hospitalists were significantly less confident about the diagnosis of a UTI than urologists in two of the clinical scenarios.

CONCLUSIONS

Standardization and implementation of consensus criteria for UTI in this high-risk population is needed.

Diagnosis and management of bladder bowel dysfunction in children with urinary tract infections: a position statement from the International Children's Continence Society

BACKGROUND

We present a consensus view from the International Children's Continence Society (ICCS) on the evaluation and management of bladder bowel dysfunction (BBD) in children with urinary tract infection (UTI). The statement aims to highlight the importance of BBD in the development and recurrence of childhood UTI and its management to reduce its associated morbidity and sequelae.

METHODS

A systematic literature search was done on PubMed, Embase, and Scopus databases until August 15, 2016. Relevant publications concerning BBD and its relationship with UTI among children were reviewed and aggregated for statements of recommendation. Discussion by the ICCS Board and a multi-disciplinary core group of authors resulted in a document available on its website for all ICCS members to review. Insights and feedback were considered with consensus and agreement reached to finalize this position statement.

RESULTS

BBD in children with UTI is summarized. Details regarding epidemiology, pathophysiology, and recommendations for general and family practitioners and pediatricians relating to the evaluation and management of this condition are presented.

CONCLUSIONS

This document serves as the position statement from ICCS, based on literature review and expert opinion providing our current understanding of BBD in children with UTI.

Predictive ability of NGAL in identifying urinary tract infection in children with neurogenic bladders

BACKGROUND

Distinguishing between urinary tract infection (UTI) and colonization (UTC) in patients with neurogenic bladders who require clean intermittent catheterization (CIC) is difficult. Urinary neutrophil gelatinase-associated lipocalin concentrations (uNGAL) are increased in UTIs. Our objective was to determine the predictive accuracy of uNGAL for UTI in CIC-dependent children.

METHODS

Cross-sectional study of CIC-dependent patients from August, 2015 to November, 2016. UTI was defined as (1) growth of ≥ 50,000 cfu/mL of a uropathogen, (2) > 10 urinary white blood cells/hpf, and (3) ≥ 2 of the following: temperature > 38 °C, abdominal pain, back pain, worsened incontinence, pain with catheterization, or malodorous/cloudy urine. Positive urine cultures that did not meet these criteria were grouped as UTC, and negative cultures were grouped as no growth.

RESULTS

Two hundred one patients were included (no growth = 100, UTC = 77, UTI = 24). Median (interquartile range) uNGAL was higher in the UTI group (UTI 1361 (931, 2516) μg/g creatinine, UTC 246 (106, 548) μg/g creatinine, no growth 36 (11, 179) μg/g creatinine, p < 0.01 for all comparisons). The area under the ROC curve for uNGAL for UTI versus no UTI was 0.89, 95% CI (0.80-0.98).

CONCLUSION

uNGAL is elevated in CIC-dependent children with UTI compared to those with negative cultures and those with UTC.

Uropathogens and Pyuria in Children With Neurogenic Bladders

: media-1vid110.1542/5727212324001PEDS-VA_2017-3006Video Abstract BACKGROUND: A recent study revealed that specific uropathogens are associated with lower odds of pyuria in a general pediatrics population. Children with neurogenic bladders who require clean intermittent catheterization (CIC) frequently have pyuria. Our objective with this study was to determine if an association exists between pyuria and type of uropathogen in CIC-dependent children.

METHODS

We obtained urinalysis and urine culture results from electronic medical records from January 2008 through December 2014 for patients ≤18 years of age with neurogenic bladders managed at a single institution. Cultures without concurrent urinalyses were excluded from analysis, as were cultures that yielded no growth, fungal growth, or growth of unidentified mixed organisms. We used logistic regression to determine the association of pyuria and leukocyte esterase with specific uropathogens.

RESULTS

We included 2420 cultures in this analysis. The growth of Enterococcus on urine culture was associated with lower odds of both pyuria and leukocyte esterase. In contrast, the growth of more than 100 000 colony-forming units per milliliter of Proteus mirabilis was associated with increased odds of both pyuria and leukocyte esterase, and the growth of Pseudomonas aeruginosa was associated with increased odds of leukocyte esterase but not pyuria. Certain etiologies of neurogenic bladder, such as bladder exstrophy and cloacal malformations, were also associated with increased odds of pyuria compared with neurogenic bladder due to myelomeningocele.

CONCLUSIONS

In children with neurogenic bladders who require CIC, Enterococcus may grow in urine culture without pyuria or positive leukocyte esterase. Accordingly, urine cultures should be obtained in symptomatic children, regardless of urinalysis results.

Survival of Cronobacter in powdered infant formula and their variation in biofilm formation

Cronobacter is a ubiquitous Gram-negative pathogen bacterium capable of surviving in low water activity environments, in particular powdered infant formula (PIF). Seven Cronobacter strains representing four different species (C. sakazakii, n = 4; C. malonaticus, n = 1; C. muytjensii, n = 1; C. turicensis, n = 1) were subjected to dry stress and stored in PIF at room temperature. The resulting survivor curves showed that Cronobacter sp. can survive for extended periods of at least 3 months with a significant, but moderate, variability regarding the level of resistance between species; however, no correlation was evident regarding the origin of strains. These results are evaluated with regard to other key characteristics, including genomic profiles and biofilm formation capacities of the strains.

SIGNIFICANCE AND IMPACT OF THE STUDY

Cronobacter can survive extended periods of at least 3 months in PIF, with moderately significant interspecific variability in desiccation resistance. Results are evaluated with regard to genomic profiles and biofilm formation capacities of the strains, and contribute to an improved understanding of the environmental persistence of Cronobacter in contaminated PIF, and subsequent risk to infant exposure.

Dosing strategies for switching from oral risperidone to paliperidone palmitate: Effects on clinical outcomes

Introduction:

There are currently no guidelines for switching patients from oral risperidone to paliperidone palmitate (Invega Sustenna®). Furthermore, the paliperidone long-acting injectable (LAI) package insert does not recommend bridging with oral antipsychotics, which may result in inadequate serum concentrations in patients on ≥4 mg/d risperidone.

Methods:

This study evaluated the effects of suboptimal dosing and bridging in patients switched from oral risperidone to paliperidone LAI on hospitalization days, emergency department (ED)/mental health urgent care visits, and no-shows/cancellations to mental health appointments. Patients were categorized into optimal or suboptimal dosing based on their loading and maintenance paliperidone doses. Patients on risperidone ≥4 mg/d were categorized as bridged if they received risperidone for ≥7 days after the first paliperidone injection.

Results:

There were no significant differences in outcomes between optimally and suboptimally dosed patients. There were statistically significant reductions in hospitalization days in patients who were bridged compared with patients who were not bridged. There were statistically significant reductions in hospitalization days and ED/mental health urgent care visits after switching to paliperidone LAI.

Discussion:

The results of this study indicate that bridging patients who are on ≥4 mg/d risperidone, when converting to paliperidone LAI, is associated with reductions in hospitalization days. However, more research is required to determine the optimal dose and duration of the bridge. The results also indicate that switching patients from oral risperidone to paliperidone LAI, even if the dose is suboptimal, is associated with reductions in hospitalization days and ED/mental health urgent care visits.
