Objective To assess the availability of resources that support the provision of basic neonatal care in eight first‐referral level (district) hospitals in Kenya. Methods We selected two hospitals each from four of Kenya’s eight provinces with the aim of representing the diversity of this part of the health system in Kenya. We created a checklist of 53 indicator items necessary for providing essential basic care to newborns and assessed their availability at each of the eight hospitals by direct observation, and then compared our observations with the opinions of health workers providing care to newborns on recent availability for some items, using a self‐administered structured questionnaire. Results The hospitals surveyed were often unable to maintain a safe hygienic environment for patients and health care workers; staffing was insufficient and sometimes poorly organised to support the provision of care; some key equipment, laboratory tests, drugs and consumables were not available while patient management guidelines were missing in all sites. Conclusion Hospitals appear relatively poorly prepared to fill their proposed role in ensuring newborn survival. More effective interventions are needed to improve them to meet the special needs of this at‐risk group.  相似文献

Background

Management of emergency general surgical conditions remains a challenge in rural sub-Saharan Africa due to issues such as insufficient human capacity and infrastructure. This study describes the burden of emergency general surgical conditions and the ability to provide care for these conditions at three rural district hospitals in Rwanda.

Methods

This retrospective cross-sectional study included all patients presenting to Butaro, Kirehe and Rwinkwavu District Hospitals between January 1st 2015 and December 31st 2015 with emergency general surgical conditions, defined as non-traumatic, non-obstetric acute care surgical conditions. We describe patient demographics, clinical characteristics, management and outcomes.

Results

In 2015, 356 patients presented with emergency general surgical conditions. The majority were male (57.2%) and adults aged 15–60 years (54.5%). The most common diagnostic group was soft tissue infections (71.6%), followed by acute abdominal conditions (14.3%). The median length of symptoms prior to diagnosis differed significantly by diagnosis type (p?<?0.001), with the shortest being urological emergencies at 1.5 days (interquartile range (IQR):1, 6) and the longest being complicated hernia at 17.5 days (IQR: 1, 208). Of all patients, 54% were operated on at the district hospital, either by a general surgeon or general practitioner. Patients were more likely to receive surgery if they presented to a hospital with a general surgeon compared to a hospital with only general practitioners (75% vs 43%, p?<?0.001). In addition, the general surgeon was more likely to treat patients with complex diagnoses such as acute abdominal conditions (33.3% vs 4.1%, p?<?0.001) compared to general practitioners. For patients who received surgery, 73.3% had no postoperative complications and 3.2% died.

Conclusion

While acute abdominal conditions are often considered the most common emergency general surgical condition in sub-Saharan Africa, soft tissue infections were the most common in our setting. This could represent a true difference in epidemiology in rural settings compared to referral facilities in urban settings. Patients were more likely to receive an operation in a hospital with a general surgeon as opposed to a general practitioner. This provides evidence to support increasing the surgical workforce in district hospitals in order to increase surgical availability for patients.

ObjectiveTo explore the hepatoprotective and antioxidant effects of piperine against acetaminophen-induced hepatotoxicity in mice.MethodsIn mice, hepatotoxicity was induced by a single dose of acetaminophen (900 mg/kg b.w. i.p.). Piperine (25 mg/kg b.w. i.p.) and standard drug silymarin (25 mg/kg b.w. i.p.) were given to mice, 30 min after the single injection of acetaminophen. After 4 h, the mice were decapitated. Activities of liver marker enzymes [(aspartate transaminase (AST), alanine transaminase (ALT), and alkaline phosphatase (ALP)] and inflammatory mediator tumour necrosis factor-alpha (TNF-α) were estimated in serum, while lipid peroxidation and antioxidant status (superoxide dismutase, catalase, glutathione peroxidase, glutathione reductase, glutathione-s-transferase and glutathione) were determined in liver homogenate of control and experimental mice.ResultsAcetaminophen induction (900 mg/kg b.w. i.p.) significantly increased the levels of liver marker enzymes, TNF-α, and lipid peroxidation, and caused the depletion of antioxidant status. Piperine and silymarin treatment to acetaminophen challenged mice resulted in decreased liver marker enzymes activity, TNF-α and lipid peroxidation levels with increase in antioxidant status.ConclusionsThe results clearly demonstrate that piperine shows promising hepatoprotective effect as comparable to standard drug silymarin.  相似文献

OBJECTIVE: This report highlights the health characteristics of four age groups of older adults-55-64 years, 65-74 years, 75-84 years, and 85 years and over-providing estimates by sex, race and Hispanic origin, poverty status, health insurance status, and marital status. METHODS: The estimates in this report were derived from the 2000-2003--National Health Interview Surveys' Family and Sample Adult questionnaires. Estimates are based on interviews with 39,990 sample adults aged 55 years and over. RESULTS: Overall, prevalence rates for fair or poor health, chronic health conditions (with the exception of diabetes), sensory impairments, and difficulties with physical and social activities increased with advancing age, doubling or even tripling between the age groups 55-64 and 85 years and over. About one in five adults aged 55-64 years were in fair or poor health, rising to about one-third of adults aged 85 years and over. Men and women were about equally likely to be in fair or poor health across the age groups studied, but women were more likely to have difficulty in physical or social activities. Sociodemographic variations in health were noted across the age groups studied, with the most consistent and striking results found for poverty status and health insurance coverage. Poor and near poor adults and those with public health insurance were, by far, the most disadvantaged groups of older adults in terms of health status, health care utilization, and health behaviors. CONCLUSIONS: Health status, health care utilization, and health-promoting behaviors among adults aged 55 and over vary considerably by age and other sociodemographic characteristics. Identifying these variations can help government and private agencies pinpoint areas of greatest need and greatest opportunity for extending years of healthy life among the Nation's seniors.  相似文献

Cervical cancer incidence worldwide exceeds half a million new cases per year. The human papillomavirus (HPV) being the major causative agent of CC uses a variety of strategies to evade immune surveillance, where the immune status varies amongst individuals. This immune evasion altered by HPV is reflected in persistent infections, causing the evolution of cervical neoplasia. The role of the immune system in viral recognition and elimination is of extreme relevance in the development of CC. The interactions of the HLA-E ligand in the target cell along with CD94/NKG2 receptors, which are expressed predominantly, but not exclusively, on NK cells’ surface, are responsible for activating or inhibiting cytotoxic activity according to their function. The engagement between HLA-E and CD94/NKG2 molecules is one of the fundamental surveillance mechanisms in patients with CIN I, II and III, where HLA-E expression increases significantly, especially in HPV 16 and 18 infections. Higher HLA-E expression was observed in most histopathological types of CC, and at the same time was correlated to best survival of the patient. This review aims to summarize and discuss the immunological role of HLA-E in the context of HPV infection and immune system evasion, and the oncogenic process of cervical cancer.  相似文献

Background

Most mortality attributable to surgical emergencies occurs in low- and middle-income countries. District hospitals, which serve as the first-level surgical facility in rural sub-Saharan Africa, are often challenged with limited surgical capacity. This study describes the presentation, management, and outcomes of non-obstetric surgical patients at district hospitals in Rwanda.

Methods

This study included patients seeking non-obstetric surgical care at three district hospitals in rural Rwanda in 2013. Demographics, surgical conditions, patient care, and outcomes are described; operative and non-operative management were stratified by hospitals and differences assessed using Fisher’s exact test.

Results

Of the 2660 patients who sought surgical care at the three hospitals, most were males (60.7 %). Many (42.6 %) were injured and 34.7 % of injuries were through road traffic crashes. Of presenting patients, 25.3 % had an operation, with patients presenting to Butaro District Hospital significantly more likely to receive surgery (57.0 %, p < 0.001). General practitioners performed nearly all operations at Kirehe and Rwinkwavu District Hospitals (98.0 and 100.0 %, respectively), but surgeons performed 90.6 % of the operations at Butaro District Hospital. For outcomes, 39.5 % of all patients were discharged without an operation, 21.1 % received surgery and were discharged, and 21.1 % were referred to tertiary facilities for surgical care.

Conclusion

Significantly more patients in Butaro, the only site with a surgeon on staff and stronger surgical infrastructure, received surgery. Availing more surgeons who can address the most common surgical needs and improving supplies and equipment may improve outcomes at other districts. Surgical task sharing is recommended as a temporary solution.
