Appointment keeping for medical review among patients with selected chronic diseases in an urban area of Uganda

Introduction: proper management of chronic diseases is important for prevention of disease complications and yet some patients miss appointments for medical review thereby missing the opportunity for proper monitoring of their disease conditions. There is limited information on missed appointments among chronic disease patients in resource limited settings. This study aimed to determine the prevalence of missed appointments for medical review and associated factors among chronic disease patients in an urban area of Uganda.

Methods: patients or caregivers of children with chronic diseases were identified as they bought medicines from a community pharmacy. They were visited at home to access their medical documents and those whose chronic disease status was ascertained were enrolled. The data was collected using: questionnaires, review of medical documents, and in-depth interviews with chronic disease patients.

Results: the prevalence of missed appointments was 42% (95%CI=35-49%). The factors associated with missed appointments were: monthly income ?30US Dollars (OR=2.56, CI=1.25–5.26), affording less than half of prescribed drugs (OR=3.92, CI=1.64–9.40), not experiencing adverse events (OR=2.66, CI=1.26–5.61), not sure if treatment helps (OR=2.84, CI=1.047.77), not having a medicines administration schedule (OR=6.77, CI=2.11–21.68), and increasing number of drugs (OR=0.72, CI=0.53–0.98). Conclusion: patients missed appointments mainly due to: financial and health system barriers, conflicting commitments with appointments, and perceptions of the disease condition. Patients should be supported with accessible and affordable health services.

The effects of Chronic Lycopene Supplementation on Exercise-Induced Oxidative Stress and Glucose Homeostasis.

Lycopene can exert antioxidant effects against peripheral and cellular oxidative stress and may be associated with reduced diabetic risk. Conversely, exercise-induced free radicals are thought to underpin many of the desirable whole-body adaptations following training and the use of antioxidants within the exercise model remains debatable. PURPOSE: To investigate the effect of lycopene supplementation on oxidative stress and glucose homeostasis following acute aerobic exercise. METHOD: Twenty-eight (n=28) apparently healthy male volunteers were recruited (age 24 ± 4 years; weight 78 ± 10 kg; height 178 ± 8 cm; 2max 40 ± 7 ml·kg-1 ·min-1 ) in a randomised, single blind, placebo-controlled study. Participants were required to attend the Laboratory on two occasions: prior to and following 6 weeks of supplementation of either 10mg lycopene (LG; n=15) or placebo (PG; n=13) followed by a bout of acute exercise for one hour at 65% 2max. Exogenous glucose oxidation was then measured on an isotope ratio mass spectrometer in a sub-group of participants (n=14) following exercise, by administration of a standard oral glucose tolerance test (OGTT; 75g glucose). Venous blood samples were drawn for measurement of oxidative stress parameters, plasma glucose and insulin. RESULTS: Plasma lycopene increased in LG only (0.01 ± 0.004 vs.0.02 ± 0.007 µmol/L; P <0.05) following supplementation and remained elevated post exercise compared to PG (0.01 ± 0.004 vs. 0.02 ± 0.009 µmol/L; P <0.05). There were no changes in other markers of oxidative stress (SOD, LOOHs, F2 ISP and Alkoxyl radical) either between or within the trials, (P >0.05, respectively). A main effect for an increase in insulin was observed two hours post OGTT in the sub-groups (Pooled data, P <0.05) but trends in the HOMA scores were evident with a 57% increase for LG (2.20 ± 1.84 vs. 5.14 ± 2.5; P >0.05) and an 11% decrease for PG (2.17 ± 1.06 vs. 1.94 ± 1.53; P >0.05). No change in plasma glucose was detected at any point, or after the OGTT (P >0.05). CONCLUSION: In healthy males, lycopene supplementation had no effect on post exercise levels of ROS or markers of lipid peroxidation, despite an increase in plasma lycopene. However, lycopene supplementation may affect post exercise insulin sensitivity in response to glucose consumption, but further parallel research is required.

A review of behaviour change theories and techniques used in group based self-management programmes for chronic low back pain and arthritis

Background: Medical Research Council (MRC) guidelines recommend applying theory within complex interventions to explain how behaviour change occurs. Guidelines endorse self-management of chronic low back pain (CLBP) and osteoarthritis (OA), but evidence for its effectiveness is weak. Objective: This literature review aimed to determine the use of behaviour change theory and techniques within randomised controlled trials of group-based self-management programmes for chronic musculoskeletal pain, specifically CLBP and OA. Methods: A two-phase search strategy of electronic databases was used to identify systematic reviews and studies relevant to this area. Articles were coded for their use of behaviour change theory, and the number of behaviour change techniques (BCTs) was identified using a 93-item taxonomy, Taxonomy (v1). Results: 25 articles of 22 studies met the inclusion criteria, of which only three reported having based their intervention on theory, and all used Social Cognitive Theory. A total of 33 BCTs were coded across all articles with the most commonly identified techniques being '. instruction on how to perform the behaviour', '. demonstration of the behaviour', '. behavioural practice', '. credible source', '. graded tasks' and '. body changes'. Conclusion: Results demonstrate that theoretically driven research within group based self-management programmes for chronic musculoskeletal pain is lacking, or is poorly reported. Future research that follows recommended guidelines regarding the use of theory in study design and reporting is warranted.
