Non-Life Threatening Maternal Morbidity: Cross Sectional Surveys from Malawi and Pakistan.

BACKGROUND: For more accurate estimation of the global burden of pregnancy associated disease, clarity is needed on definition and assessment of non-severe maternal morbidity. Our study aimed to define maternal morbidity with clear criteria for identification at primary care level and estimate the distribution of and evaluate associations between physical (infective and non-infective) and psychological morbidities in two different low-income countries. METHODS: Cross sectional study with assessment of morbidity in early pregnancy (34%), late pregnancy (35%) and the postnatal period (31%) among 3459 women from two rural communities in Pakistan (1727) and Malawi (1732). Trained health care providers at primary care level used semi-structured questionnaires documenting signs and symptoms, clinical examination and laboratory tests which were bundled to reflect infectious, non-infectious and psychological morbidity. RESULTS: One in 10 women in Malawi and 1 in 5 in Pakistan reported a previous pregnancy complication with 1 in 10 overall reporting a previous neonatal death or stillbirth. In the index pregnancy, 50.1% of women in Malawi and 53% in Pakistan were assessed to have at least one morbidity (infective or non-infective). Both infective (Pakistan) and non-infective morbidity (Pakistan and Malawi) was lower in the postnatal period than during pregnancy. Multiple morbidities were uncommon (<10%). There were marked differences in psychological morbidity: 26.9% of women in Pakistan 2.6% in Malawi had an Edinburgh Postnatal Depression Score (EPDS) > 9. Complications during a previous pregnancy, infective morbidity (p <0.001), intra or postpartum haemorrhage (p <0.02) were associated with psychological morbidity in both settings. CONCLUSIONS: Our findings highlight the need to strengthen the availability and quality of antenatal and postnatal care packages. We propose to adapt and improve the framework and criteria used in this study, ensuring a basic set of diagnostic tests is available, to ensure more robust assessment of non-severe maternal morbidity.

Improving care for patients on antiretroviral therapy through a gap analysis framework.

OBJECTIVE: To improve quality of care through decreasing existing gaps in the areas of coverage, retention, and wellness of patients receiving HIV care and treatment. DESIGN: The antiretroviral therapy (ART) Framework utilizes improvement methods and the Chronic Care Model to address the coverage, retention, and wellness gaps in HIV care and treatment. This is a time-series study. SETTING: The ART Framework was applied in five health centers in Buikwe District, Uganda. PARTICIPANTS: Quality improvement teams, consisting of healthcare workers and expert patients, were established in each of the five healthcare facilities. INTERVENTION: The intervention period was October 2010 to September 2012. It consisted of quality improvement teams analyzing their facility and systems of care from the perspective of the Chronic Care Model to identify areas of improvement. They implemented the ART Framework, collected data and assessed outcomes, focused on self-management support for patients, to improve coverage, retention, and wellness gaps in HIV care and treatment. MAIN OUTCOME MEASURE(S): Coverage was defined as every patient who needs ART in the catchment area, receives it. Retention was defined as every patient who receives ART stays on ART, and wellness defined as having a positive clinical, immunological, and/or virological response to treatment without intolerable or unmanageable side-effects. RESULTS: Results from Buikwe show the gaps in coverage, retention, and wellness greatly decreased a gap in coverage of 44-19%, gap in retention of 49-24%, and gap in wellness of 53-14% during a 2-year intervention period. CONCLUSION: The ART Framework is an innovative and practical tool for HIV program managers to improve HIV care and treatment.

Factors associated with preterm, early preterm and late preterm birth in Malawi.

BACKGROUND: Assessment of risk factors for preterm birth in a population with high incidence of preterm birth and HIV infection. METHODS: Secondary analysis of data for 2,149 women included in a community based randomized placebo controlled trial for the prevention of preterm birth (APPLe trial (ISRCTN84023116) with gestational age at birth determined through ultrasound measurement in early pregnancy. Multivariate Logistic Regression analyses to obtain models for three outcome variables: all preterm, early preterm, and late preterm birth. FINDINGS: No statistical differences were noted for the prevalence of HIV infection (p = 0.30) or syphilis (p = 0.12) between women who delivered preterm versus term. BMI (Adjusted OR 0.91 (0.85-0.97); p = 0.005) and weight gain (Adjusted OR 0.89 (0.82-0.97); p = 0.006) had an independent, protective effect. Previous preterm birth doubled the odds of preterm birth (Adjusted OR 2.13 (1.198-3.80); p = 0.01). Persistent malaria (despite malaria prophylaxis) increased the risk of late preterm birth (Adjusted OR 1.99 (1.05-3.79); p = 0.04). Age <20 (Adjusted OR 1.73 (1.03-2.90); p = 0.04) and anemia (Adjusted OR 1.95 (1.08-3.52); p = 0.03) were associated with early preterm birth (<34 weeks). CONCLUSIONS: Despite claims that HIV infection is an important cause of preterm birth in Africa, we found no evidence of an association in this population (unexposed to anti-retroviral treatment). Persistent malaria was associated with late preterm birth. Maternal undernourishment and anemia were independently associated with early preterm birth. The study did not assess whether the link was direct or whether a common precursor such as chronic infection was responsible for both maternal effects and early labour.

Introducing new technology safely.

AIM: This report considers the introduction of new technology and the implications for patient safety. METHODS AND DISCUSSION: A distinction is made between 'conceptually' new and 'contextually' new technology. The life cycle of technology from development to routine use is discussed and the key role for regulation, health technology assessment, clinical engineering and surveillance in this life cycle considered. The limitations of each of these disciplines are also discussed. Special consideration is given to the needs of developing countries. Case study examples of particular challenges in the safe introduction of technology are presented.

Influence of context on the production of complex sentences by typically developing children.

PURPOSE: This study was designed to identify types of complex-sentence meanings (i.e., content) produced in selected elicitation contexts by typically developing children within 3 different age groups. The research was motivated by the need for additional evidence-based assessments and interventions for children with language disorders. METHOD: Participants included 3 groups of typically developing children, mean ages 2;8 (years;months; Cohort 1), 3;4 (Cohort 2), and 4;7 (Cohort 3). Four elicitation contexts distinguished on the basis of degree of spontaneity and the potential for eliciting complex sentences were used: free-play, script-play, elicited description, and story retelling. Tasks within these contexts were presented to each child over two 1-hr sessions. RESULTS: Significant differences were found among the cohorts for proportion of complex-sentence productions overall, across contexts, and across content categories. Significant relationships were found between content and contexts and between adult model and content of the child's following utterance. CONCLUSIONS: Findings suggest that children's complex-sentence production changes with development and is sensitive to features of linguistic and nonlinguistic contexts. These data provide evidence for the types of complex-sentence content that may be expected in specified contexts, thus serving as a basis for planning assessment and intervention for children with language disorders.

Determinants of salt sensitivity in black and white normotensive and hypertensive women.

Salt sensitivity (SS) has been linked to human hypertension. We examined ethnic differences in the relation between SS; erythrocyte sodium (Na+i), calcium (Ca2+i), potassium (K+i), and magnesium (Mg2+i); and sodium pump activity in African-American (AA) and white women. In a crossover protocol, similar numbers of normotensive, hypertensive, AA, and white women were randomized to 7 days of a 20 meq/d and a >200 meq/d salt diet (n=199). After an overnight inpatient stay, group differences in supine blood pressure (BP), heart rate, erythrocyte cations, and sodium pump activity were measured. The prevalence of SS (53.5% vs 51%) and salt resistance (26.3% vs 30.0%) was similar in both races. Greater mean BP increase with salt loading was seen in AA vs white hypertensives but not between the normotensive women. In hypertensives, increase in mean arterial pressure was 12.6 vs 8.2 mm Hg in AAs vs whites, respectively (P<0.01), and for systolic BP, it was 23 vs 14.8 mm Hg (P<0.01). Higher Na+i and Ca2+i were noted in SS and salt-intermediate AA than in the corresponding white subjects. Na+i, Ca2+i, and the ratios of Na+i to K+i and of Ca2+i to Mg2+i were positively correlated with salt responsiveness in AA but not in white women. Sodium pump activity was similar between groups, although the change in maximal activity trended to vary inversely with SS in AA. In closely matched AA and white women, the prevalence of SS is similarly high in both races, although the magnitude of BP increase is greater in AA hypertensives. In AA but not in whites, SS is positively associated with Na+i, Ca2+i, and the ratios of Na+i to K+i and of Ca2+i to Mg2+i.
