In Tanzania, the coverage of four or more antenatal care (ANC 4) visits among pregnant women has declined over time. We conducted an exploratory analysis to identify factors associated with utilization of ANC 4 and ANC 4 decline among pregnant women over time. We used data from 8035 women who delivered within two years preceding Tanzania Demographic and Health Surveys conducted in 1999, 2004/05 and 2010. Multivariate logistic regression models were used to examine the association between all potential factors and utilization of ANC 4; and decline in ANC 4 over time. Factors positively associated with ANC 4 utilization were higher quality of services, testing and counseling for HIV during ANC, receiving two or more doses of SP (Sulphadoxine Pyrimethamine)/Fansidar for preventing malaria during ANC and higher educational status of the woman. Negatively associated factors were residing in a zone other than Eastern zone, never married woman, reported long distance to health facility, first ANC visit after four months of pregnancy and woman's desire to avoid pregnancy. The factors significantly associated with decline in utilization of ANC 4 were: geographic zone and age of the woman at delivery. Strategies to increase ANC 4 utilization should focus on improvement in quality of care, geographic accessibility, early ANC initiation, and services that allow women to avoid pregnancy. The interconnected nature of the Tanzanian Health System is reflected in ANC 4 decline over time where introduction of new programs might have had unintended effects on existing programs. An in-depth assessment of the recent policy change towards Focused Antenatal Care and its implementation across different geographic zones, including its effect on the perception and understanding among women and performance and counseling by health providers can help explain the decline in ANC 4.

Background & Aims: Gastroparesis is a chronic disorder of the stomach characterized by nausea, vomiting, early satiety, postprandial fullness, and abdominal pain. There is limited information on gastroparesis in minority populations. We assessed ethnic, racial, and sex variations in the etiology, symptoms, quality of life, gastric emptying, treatments, and symptom outcomes of patients with gastroparesis. Methods: We collected information from the National Institutes of Health Gastroparesis Consortium on 718 adult patients, from September 2007 through December 2017. Patients were followed every 4 or 6 months, when data were collected on medical histories, symptoms (based on answers to the PAGI-SYM questionnaires), and quality of life (based on SF-36). Follow-up information collected at 1 year (48 week) was used in this analysis. Comparisons were made

We examined the possibility of the involvement of endothelin (ET)‐1, a potent vasoactive peptide, in the process of astrocyte proliferation after brain injury. Acute brain damage in rats was induced by cold‐injury. Astrocytes changed from a differentiated state to an immature, RC‐1‐positive state immediately after the injury. In the injured site, the level of ET‐1‐like immunoreactivity in the tissue was significantly increased on the first postoperative day and was sustained at a high level for 5 days. ETB receptor mRNA was markedly but transiently down‐regulated only on the first day after the injury. Brain extracts (BE) were prepared from the injured tissues, and their effects on the proliferative characteristics of astrocytes were examined in primary culture of astrocytes. The flat morphology, which was observed in association with cell proliferation, and DNA synthesis of astrocytes were enhanced by treatment with each of the BE from 1 (D1‐BE), 3 and 5 days after the injury. A monoclonal antibody that recognizes the C‐terminus of rat ET‐1 and ET‐3 inhibited the DNA synthesis of astrocytes induced by D1‐BE. These results provide experimental evidence that ET‐1 may participate in the initiation of gliosis in the acute phase of brain damage. J. Neurosci. Res. 47:590–602, 1997. © 1997 Wiley‐Liss, Inc.

Background Gastric electrical stimulation (GES) for treating gastroparesis symptoms is controversial. Methods We studied 319 idiopathic or diabetic gastroparesis symptom patients from the Gastroparesis Clinical Research Consortium (GpCRC) observational studies: 238 without GES and 81 with GES. We assessed the effects of GES using change in GCSI total score and nausea/vomiting subscales between baseline and 48 weeks. We used propensity score methods to control for imbalances in patient characteristics between comparison groups. Key Results GES patients were clinically worse (40% severe vs. 18% for non‐GES; P < .001); worse PAGI‐QOL (2.2. vs. 2.6; P = .003); and worse GCSI total scores (3.5 vs. 2.8; P < .001). We observed improvements in 48‐week GCSI total scores for GES vs. non‐GES: improvement by ≥ 1‐point (RR = 1.63; 95% CI = (1.14, 2.33); P = .01) and change from enrollment (difference = −0.5 (−0.8, −0.3); P < .001). When adjusting for patient characteristics, symptom scores were smaller and not statistically significant: improvement by ≥ 1‐point (RR = 1.29 (0.88, 1.90); P = .20) and change from the enrollment (difference = −0.3 (−0.6, 0.0); P = .07). Of the individual items, the nausea improved by ≥ 1 point (RR = 1.31 (1.03, 1.67); P = .04). Patients with GCSI score ≥ 3.0 tended to improve more than those with score < 3.0. (Adjusted P = 0.02). Conclusions and Inferences This multicenter study of gastroparesis patients found significant improvements in gastroparesis symptoms among GES patients. Accounting for imbalances in patient characteristics, only nausea remained significant. Patients with greater symptoms at baseline improved more after GES. A much larger sample of patients is needed to fully evaluate symptomatic responses and to identify patients likely to respond to GES.
