Midwifery practice and maternity services: A multisite descriptive study in Latin America and the Caribbean.

OBJECTIVE: over the past three decades there has been a social movement in Latin American countries (LAC) to support humanised, physiologic birth. Rates of caesarean section overall in Latin America are approximately 35%, increasing up to 85% in some cases. There are many factors related to poor outcomes with regard to maternal and newborn/infant health in LAC countries. Maternal and perinatal outcome data within and between countries is scarce and inaccurate. The aims of this study were to: i) describe selected obstetric and neonatal outcomes of women who received midwifery care, ii) identify the level of maternal well-being after experiencing midwifery care in 6 Latin America countries. DESIGN: this was a cross sectional and descriptive study, conducted in selected maternity units in Argentina, Brazil, Chile, the Dominican Republic, Peru, and Uruguay. Quantitative methods were used to measure midwifery processes of care and maternal perceptions of well-being in labour and childbirth through a validated survey of maternal well-being and an adapted version of the American College of Nurse-Midwives (ACNM) standardized antepartum and intrapartum data set. SETTING: Maternity units from 6 Latin American countries. PARTICIPANTS: the final sample was a convenience sample, and the total participants for all sites in the six countries was 3009 low risk women. FINDINGS: for the countries reporting, overall, 82% of these low risk women had spontaneous vaginal deliveries. The rate of caesarean section was 16%; the Dominican Republic had the highest rate of Caesarean sections (30%) and Peru had the lowest rate (4%). The use of oxytocin in labour was widely variable, although overall there was a high proportion of women whose labour was augmented or induced. Ambulation was common, with the lowest proportion (48%) of women ambulating in labour in Chile, Uruguay (50%), Peru (65%), Brazil (85%). The presence of continuous support was highest in Uruguay (93%), Chile (75%) and Argentina (55%), and Peru had the lowest (22%). Episiotomies are still prevalent in all countries, the lowest rate was reported in the Dominican Republic (22%), and the highest rates were 52 and 53% (Chile and Peru, respectively). The Optimal Maternal well-being score had a prevalence of 43.5%, adequate score was 30.8%; 25% of the total sample of women rated their well-being during labour and childbirth as poor. KEY CONCLUSIONS: despite evidence-based guidelines and recommendations, birth is not managed accordingly in most cases. Women feel that care is adequate, although some women report mistreatment. IMPLICATIONS FOR PRACTICE: More research is needed to understand why such high levels of intervention exist and to test the implementation of evidence-based practices in local settings.

Prevalence of diabetes, prediabetes, and stress hyperglycemia: insulin therapy and metabolic control in patients on total parenteral nutrition (prospective multicenter study).

OBJECTIVE: The prevalence of carbohydrate metabolism disorders in patients who receive total parenteral nutrition (TPN) is not well known. These disorders can affect the treatment, metabolic control, and prognosis of affected patients. The aims of this study were to determine the prevalence in noncritically ill patients on TPN of diabetes, prediabetes, and stress hyperglycemia; the factors affecting hyperglycemia during TPN; and the insulin therapy provided and the metabolic control achieved. METHODS: We undertook a prospective multicenter study involving 19 Spanish hospitals. Noncritically ill patients who were prescribed TPN were included, and data were collected on demographic, clinical, and laboratory variables (glycated hemoglobin, C-reactive protein [CRP], capillary blood glucose) as well as insulin treatment. RESULTS: The study included 605 patients. Before initiation of TPN, the prevalence of known diabetes was 17.4%, unknown diabetes 4.3%, stress hyperglycemia 7.1%, and prediabetes 27.8%. During TPN therapy, 50.9% of patients had at least one capillary blood glucose of >180 mg/dL. Predisposing factors were age, levels of CRP and glycated hemoglobin, the presence of diabetes, infectious complications, the number of grams of carbohydrates infused, and the administration of glucose-elevating drugs. Most (71.6%) patients were treated with insulin. The mean capillary blood glucose levels during TPN were: known diabetes (178.6 ± 46.5 mg/dL), unknown diabetes (173.9 ± 51.9), prediabetes (136.0 ± 25.4), stress hyperglycemia (146.0 ± 29.3), and normal (123.2 ± 19.9) (P<.001). CONCLUSION: The prevalence of carbohydrate metabolism disorders is very high in noncritically ill patients on TPN. These disorders affect insulin treatment and the degree of metabolic control achieved.

A community-based participatory research approach to explore community perceptions of the quality of maternal-newborn health services in the Dominican Republic.

OBJECTIVE: to understand both men's and women's beliefs and attitudes regarding public maternity and newborn services, care and quality. DESIGN: qualitative, cross-sectional, retrospective study with an observation arm, using community-based participatory research as both the mechanism of enquiry and catalyst for change. SETTING: four urban neighbourhoods in the Dominican Republic, selected in collaboration with the Provincial Medical Public Health Director and the partnering local public hospital. PARTICIPANTS: adolescent women (15-20 years of age), adult women (21-49 years of age) and adult men (>19 years of age) from the four neighbourhoods were recruited to participate in focus sessions, personal interviews and/or antenatal observations. A total number of 137 participants were recruited: 27 males, 51 adolescent females and 59 adult females. The attrition rate was 17% (n=23). Dominican and US midwives and nurses, as well as community leaders, comprised the research team. MEASUREMENTS AND FINDINGS: following informed consent, self-reported demographics and obstetric history were collected. Twelve focus groups and 12 individual interviews were recorded and transcribed, then qualitatively analysed for content and interpretation of salient themes. Antenatal observations were performed by community leaders to identify patterns of antenatal health-care delivery and utilisation. The main over-riding theme uncovered by the research was 'no me hace caso', or that women and men accessing the maternal health system did not feel valued. The significant amount of time required to receive care was interpreted by the participants as a lack of respect. Finally, the idea of 'cuña' emerged, in which participants noted special treatment for those with social connections to health-care providers. Presentation to the hospital was challenging but resulted in hospital volunteers joining the community volunteer group to collaborate on improving services. KEY CONCLUSIONS AND IMPLICATIONS: this study, conducted in the Dominican Republic, illustrates international collaboration between university researchers, maternity service providers and community members. Community-based participatory research may be an effective mechanism to unite community members and health providers in the common mission to improve maternal-newborn health services.

Evaluation of bone disease in morbidly obese women after gastric bypass and risk factors implicated in bone loss.

BACKGROUND: In patients undergoing gastric bypass, massive weight loss and impairment of calcium intake and absorption in the duodenum and proximal jejunum may increase the risk of bone mass loss and fractures. However, few data are available regarding the impact of this surgery on the skeleton. The aim of our study was to examine the skeletal changes in a cohort of morbidly obese Caucasian women during the first year after gastric bypass and to analyse the factors implicated in the development of bone loss. METHODS: Sixty-two morbidly obese white women aged 45.3 +/- 8.9 years were studied. Anthropometric measurements, bone mineral density (BMD) screening using dual-energy X- ray absorptiometry and plasma determinations of calcium, phosphorus, parathyroid hormone (PTH), 25-hydroxyvitamin D [25(OH) D(3)] and insulin-like growth factor-I (IGF-I) were made prior to and 12 months after surgery. RESULTS: A year after surgery, BMD significantly decreased at the femoral neck (10.2 +/- 5.7%) and at the lumbar spine (3.2 +/- 4.4%). In the follow-up, 16.1% of women had osteopenia at the femoral neck and 19.3% at the lumbar spine, and 1.6% developed osteoporosis at the lumbar spine. Patients with bone disease were significantly older; the percentage of women with menopause was greater in this group and had lower initial and final values of lean mass. However, no differences in body mass index, weight loss, fat mass, calcium, PTH, 25(OH) D(3) or IGF-I values were found between groups. In the logistic regression analysis, lean mass 12 months after surgery and menopause were found to be the main determinants of osteopenia after adjusting for age with odds ratios of 0.82 and 9.13, respectively. CONCLUSIONS: There is a significant BMD loss at the femoral neck and lumbar spine a year after gastric bypass. Menopausal patients and those with greater lean mass loss are at greater risk and, consequently, should be closely followed up with periodic densitometries.

Midwifery curriculum for auxiliary maternity nurses: a case study in the Dominican Republic.

Although most deliveries in the Dominican Republic occur within hospitals, maternal mortality in that nation remains high. In nonteaching hospitals, almost all of the vaginal births are attended by maternity auxiliary nurses. This article reports on a series of educational conferences for maternity auxiliary nurses in 1 hospital that were developed in response to the maternal mortality rate there. These conferences, taught by a team of midwives from the continental United States and Puerto Rico, used a midwifery curriculum with a participatory action methodology. The educational initiative has developed into a nongovernmental organization named Proyecto ADAMES to build capacity among auxiliary nurses. A qualitative evaluation of the effectiveness of Proyecto ADAMES in improving the knowledge, skills, and attitudes of the auxiliary nurses revealed positive behavioral changes despite weak documentation of their newly acquired knowledge and skills. Findings suggest that midwifery education for auxiliary maternity nurses in the Dominican Republic may contribute to maternal mortality reduction.
