This study looked at the combined effects of maternal age, fetal sex and parity in a specialist hospital setting and compared it with already published figures obtained from public health-care data in Nigeria. The results show a relationship exists with bivariate analysis between these variables and birth weight, but with multivariate analysis the relationship proves to be spurious. Socio-economic status and maternal health were felt to be the most important considerations within the specialist hospital setting, as patients who attend are more likely to be of high socio-economic status and therefore on a higher income and better educated. This has a beneficial impact on maternal health and a positive outcome on birth weight. 相似文献

Multidrug-resistant bacteria pose a major challenge to the clinical management of infections in resource-poor settings. Although nontyphoidal Salmonella (NTS) bacteria cause predominantly enteric self-limiting illness in developed countries, NTS is responsible for a huge burden of life-threatening bloodstream infections in sub-Saharan Africa. Here, we characterized nine S. Typhimurium isolates from an outbreak involving patients who initially failed to respond to ceftriaxone treatment at a referral hospital in Kenya. These Salmonella enterica serotype Typhimurium isolates were resistant to ampicillin, chloramphenicol, cefuroxime, ceftriaxone, aztreonam, cefepime, sulfamethoxazole-trimethoprim, and cefpodoxime. Resistance to β-lactams, including to ceftriaxone, was associated with carriage of a combination of blaCTX-M-15, blaOXA-1, and blaTEM-1 genes. The genes encoding resistance to heavy-metal ions were borne on the novel IncHI2 plasmid pKST313, which also carried a pair of class 1 integrons. All nine isolates formed a single clade within S. Typhimurium ST313, the major clone of an ongoing invasive NTS epidemic in the region. This emerging ceftriaxone-resistant clone may pose a major challenge in the management of invasive NTS in sub-Saharan Africa. 相似文献

BACKGROUND: Diabetes-related morbidity and mortality are primarily attributable to complications such as heart disease, stroke, lower extremity amputation, kidney disease, blindness, and visual impairment, many of which potentially can be delayed or prevented. METHODS: We examined the association of diabetes self-management education (DSME) with preventive health practices and behaviors among 22,682 persons with type 2 diabetes using data from the 2001 and 2002 Behavioral Risk Factor Surveillance System (BRFSS). BRFSS is an ongoing, state-based, random-digit-dialed telephone survey of noninstitutionalized adults aged > or = 18 years. RESULTS: Approximately 48% of all adults with type 2 diabetes had never attended a DSME course. Among both diabetic persons who used insulin and those who did not, persons who received DSME were significantly more likely than those who had not received training to be physically active, to have received an annual dilated eye exam and flu vaccine, to have received a pneumococcal vaccine, to have checked their blood sugar daily, and to have had a physician or other health professional check their feet for sores or irritations and their hemoglobin A1C level in the past year. CONCLUSIONS: These data indicate the importance of DSME in the promotion of health practices that could prevent or delay potential diabetes complications among persons with type 2 diabetes. 相似文献

OBJECTIVE: To determine whether mental distress among diabetic persons is associated with various CVD risk factors. METHODS: Behavioral Risk Factors Surveillance System, an ongoing, statebased, random-digit-dialed telephone survey of the noninstitutionalized US adult population. RESULTS: Diabetic persons with mental distress were more likely than those without mental distress to smoke to have hypercholesterolemia and hypertension and not to engage in leisure-time physical activity. CONCLUSIONS: Mental health professionals need to be involved in the care of diabetic persons so they can recognize and treat symptoms of mental distress and participate in research to identify interventions that can reduce mental distress and reinforce healthy behaviors. 相似文献
