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.
