Testing the Safe Abortion Care model in Ethiopia to monitor service availability, use, and quality

Objective

To implement the Safe Abortion Care (SAC) model in public health facilities in the Tigray region of Ethiopia and document the availability, utilization, and quality of SAC services over time.

Methods

The project oriented providers in 50 public health facilities in Tigray to the SAC model. Changes in SAC indicators between baseline and endline were assessed using a retrospective review of procedure logbooks at baseline and prospective monitoring of procedure logbooks for facility performance after introduction of the SAC model.

Results

Availability of SAC services increased from 39% to 86% of the recommended number of 5 facilities per 500 000 population, primarily as a result of functional improvements at health centers. Decentralization was accompanied by a 94% increase in the annualized number of women who received services. The proportion of uterine evacuation procedures for induced abortion rose from 7% to 60% (P < 0.01), and the proportion performed with recommended technology increased from 30% to 85% (P < 0.01). The proportion of abortion patients who received modern contraception also increased from 31% to 78% (P < 0.01).

Discussion

While widespread service delivery improvements were recorded using the SAC monitoring approach, the project design was built around existing programmatic activities of the local health authority and reflects some related research limitations. For example, there was no comparison group of facilities, timing did not allow for prospective collection of the baseline data before the intervention, and facilities received different levels of monitoring support.

Conclusion

Using the SAC model, public health facilities tracked progress and made needed adjustments, which improved service delivery. Continued focus on critical safe abortion care elements should increase the availability, quality, and use of life‐saving care to reduce preventable abortion mortality in the region.     

International application of health literacy measures: Adaptation and validation of the newest vital sign in The Netherlands

Objective

The newest vital sign assesses individual reading and numeracy skills. The aim of this study was to create a Dutch version (NVS-D) and to assess its feasibility, reliability, and validity in The Netherlands.

Methods

We performed a qualitative study among experts (n = 27) and patients (n = 30) to develop the NVS-D and to assess its feasibility. For validation, we conducted a quantitative survey (n = 329). Reliability was assessed by Cronbach's alpha. Construct validity was examined by analyzing association patterns. Receiver operating characteristic (ROC) curves determined optimal cut-off scores.

Results

Cronbach's alpha was 0.76. In accordance with a priori hypotheses we found strong associations between NVS-D, general vocabulary, prose literacy and objective health literacy, and weaker associations between NVS-D and subjective health literacy. A score of ≥4 out of 6 best distinguished individuals with adequate versus inadequate health literacy.

Conclusion

The results suggest that the NVS-D is a reliable and valid tool that allows international comparable health literacy research in The Netherlands.

Practice implications

The NVS-D can be applied in research on the role of health literacy in health and health care, and the development of interventions. The methods can be applied in cross-cultural adaptation of health literacy measures in other countries.     

The tuberculosis challenge in a rural South African HIV programme

Background  

South Africa remains the country with the greatest burden of HIV-infected individuals and the second highest estimated TB incidence per capita worldwide. Within South Africa, KwaZulu-Natal has one of the highest rates of TB incidence and an emerging epidemic of drug-resistant tuberculosis.     

Lack of differential pattern in central adiposity and metabolic syndrome in Barrett's esophagus and gastroesophageal reflux disease

Obesity is an established risk factor for esophageal adenocarcinoma, although the mechanism is unclear. A pathway from reflux to inflammation through metaplasia is the dominant hypothesis, and an added role relating to visceral adiposity and the metabolic syndrome has been mooted in Barrett's esophagus (BE) patients. Whether BE differs from gastroesophageal reflux disease (GERD) in obesity and metabolic syndrome profiles is unclear, and this was the focus of this study. Patients with proven BE or GERD were randomly selected from the unit data registry and invited to attend for metabolic syndrome screening, anthropometry studies including segmental body composition analysis, and laboratory tests including fasting lipids, insulin, and C‐reactive protein. Metabolic syndrome was defined using the National Cholesterol Education Program (NCEP) and the International Diabetes Federation (IDF) criteria. One hundred and eighteen BE patients and 113 age‐ and sex‐matched GERD controls were studied. The incidence of obesity (body mass index >30 kg/m²) was 36% and 38%, respectively, with the pattern of fat deposition predominantly central and an estimated trunk fat mass of 13 and 14 kg, respectively. Using the NCEP criteria, metabolic syndrome was significantly more common in the BE cohort (30% vs 20%, P < 0.05), but there was no significant difference using IDF criteria (42% vs 37%, P= 0.340). Central obesity and the metabolic syndrome are common in both Barrett's and GERD cohorts, but not significantly different, suggesting that central obesity and the metabolic syndrome does not per se impact on the development of BE in a reflux population. In BE, the importance of obesity and the metabolic syndrome in disease progression merits further study.     

Subject Specific Optimisation of the Stiffness of Footwear Material for Maximum Plantar Pressure Reduction

Current selection of cushioning materials for therapeutic footwear and orthoses is based on empirical and anecdotal evidence. The aim of this investigation is to assess the biomechanical properties of carefully selected cushioning materials and to establish the basis for patient-specific material optimisation. For this purpose, bespoke cushioning materials with qualitatively similar mechanical behaviour but different stiffness were produced. Healthy volunteers were asked to stand and walk on materials with varying stiffness and their capacity for pressure reduction was assessed. Mechanical testing using a surrogate heel model was employed to investigate the effect of loading on optimum stiffness. Results indicated that optimising the stiffness of cushioning materials improved pressure reduction during standing and walking by at least 16 and 19% respectively. Moreover, the optimum stiffness was strongly correlated to body mass (BM) and body mass index (BMI), with stiffer materials needed in the case of people with higher BM or BMI. Mechanical testing confirmed that optimum stiffness increases with the magnitude of compressive loading. For the first time, this study provides quantitative data to support the importance of stiffness optimisation in cushioning materials and sets the basis for methods to inform optimum material selection in the clinic.     

Reduced susceptibility to dextran sulphate sodium-induced colitis in the interleukin-2 heterozygous (IL-2) mouse

Summary Mice homozygous for an inactivation of the interleukin-2 (IL-2) gene develop a T-cell dependent colitis. Heterozygous (IL-2+/-) mice are clinically healthy but have been shown to express reduced levels of IL-2 in the colon. Splenocytes from the IL-2+/- mice had a poorer proliferative response to polyclonal T-cell activation and these mice have reduced numbers of intestinal regulatory T cells (CD4+ CD25+ cells) when compared to wild type mice. When exposed to dextran sulphate sodium (DSS) IL-2+/- mice showed a markedly reduced susceptibility to DSS-induced colitis. While DSS treatment caused a marked increase in both CD4+ and CD8+ colonic T cells expressing increased levels of IL-2, IL-4, and IL-10 in wild type mice none of these changes were seen in IL-2+/- mice. On the contrary, cytokine expression in intestinal T cells of IL-2+/- mice was actually reduced after DSS treatment. These results suggest that reduced levels of IL-2 leads to attenuated activation and function of intestinal T cells in IL-2+/- mice and a failure to react adequately to DSS exposure.     

Health-related quality of life measured by the SF12 in working populations: associations with psychosocial work characteristics

This study investigated the contribution of psychosocial work characteristics (decision latitude, job demand, social support at work, and effort-reward imbalance) to health-related quality of life. Data were derived from 2 aircraft manufacturing plants (N=1,855) at the start of a longitudinal study. Regression analysis showed that work characteristics (1st model) explained 19% of the variance in the mental summary score of the Short Form-12 Health Survey. R2 change for work characteristics decreased to 13%, accounting for demographics, socioeconomic status, body mass index, and medical condition (5th model). Including health behavior and personality factors (full model), R2 change for work characteristics remained significant. Psychosocial work characteristics account for relevant proportions in the subjective perception of mental health beyond a wide array of medical variables and personality factors.     

A probabilistic approach to measure the strength of bone cell adhesion to chemically modified surfaces

Patterned surfaces with alternating regions of amino silanes [N-(2-aminoethyl)-3-aminopropyl-trimethoxysilane (EDS)] and alkyl silanes [dimethyldichlorosilane (DMS)] have been used to alter the kinetics of spatial distribution of cellsin vitro. In particular, we have previously observed the preferential spatial distribution of bone cells on the EDS regions of EDS/DMS patterned surfaces (10). In this study, we examined whether the mechanism of spatial distribution of cells on the EDS regions was adhesion mediated. Homogeneous layers of EDS and DMS were immobilized on quartz substrates and characterized by contact angle, X-ray photoelectron spectroscopy, and spectroscopic ellipsometry. The strength of bone cell attachment to the modified substrates was examined using a radial flow apparatus, within either 20 min or 2 hr of cell incubation in the presence of serum. A Weibull distribution was chosen to characterize the strength of cell-substratum adhesion. Within 20 min of cell exposure, the strength of adhesion was significantly larger on EDS and clean surfaces, compared with DMS surfaces (p<0.0001). Within 2 hr of cell incubation, there was no statistical difference between the strength of cell adhesion to EDS, DMS, and clean surfaces. The results of this study suggest that the surface chemistry mediates adhesion-based spatial cell arrangement through a layer of adsorbed serum proteins.
