The nuclear medicine bleeding scan is frequently insufficient to locate sites of bleeding precisely, in spite of its great sensitivity. A small, hand-held Geiger-Müller counter, placed directly on exposed intestine in the operating room, enables precise location of the probable bleeding site. In three patients, the technique allowed a minimal amount of intestine to be resected, distinguished between large- and small-intestinal hemorrhage, and eliminated other foci as sites of bleeding.  相似文献

由于治疗方法的进步,近80%的儿童和青少年癌症患者能够长期生存。在美国,约有270000例儿童癌症的幸存者,即每640名20至39岁成年人中就有一名幸存者。大量的幸存者有利于儿童癌症治疗后长期健康结果的研究。现在可以明确的是,化疗和放疗所致的儿童各器官系统损害在临床上可能潜伏多年。为了全面了解治疗儿童癌症而继发的健康问题,重要的是衡量三项长期结果:健康状况、死亡率和患病率。这三项中,关于前两项已有相当好的研究报道。在一项对20227例癌症5年生存者的回顾性分析中,Mertens等发现以下原因导致的超额死亡率具有统计学意义:继发癌症(…  相似文献

Paternal involvement in children's lives is associated with a variety of child outcomes, including improved cognition, improved mental health, reduced obesity rates, and asthma exacerbation. Given this evidence, the American Academy of Pediatrics has promoted actions by pediatricians to engage fathers in pediatric care. Despite these recommendations, the mother–child dyad, rather than the mother–father–child triad, remains a frequent focus of care. Furthermore, pediatric care is often leveraged to improve maternal health, such as screening for maternal depression, but paternal health is infrequently addressed even as men tend to exhibit riskier behaviors, poorer primary care utilization, and lower life expectancy. Therefore, increasing efforts by pediatric clinicians to engage fathers may affect the health of both father and child. These efforts to engage fathers are informed by currently used definitions and measures of father involvement, which are discussed here. Factors described in the literature that affect father involvement are also summarized, including culture and context; interpersonal factors; logistics; knowledge and self-efficacy; and attitudes, beliefs, and incentives. Innovative ways to reach fathers both in the clinic and in other settings are currently under investigation, including use of behavior change models, motivational interviewing, mobile technologies, peer support groups, and policy advocacy efforts. These modalities show promise in effectively engaging fathers and improving family health.  相似文献

Introduction

Nepal has pledged to substantially reduce maternal and newborn death by 2030. Improving quality of intrapartum health services will be vital to reduce these deaths. This paper examines quality of delivery and newborn services in health facilities of Nepal.

Methods

Data were sourced from the Nepal Health Facility Survey 2015, which covered a national representative sample of health facilities. The datasets were analysed to assess service readiness, availability and quality of delivery and newborn care in a sample of 992 health facilities.

Results

Of the 992 facilities in the sample, 623 provided delivery and newborn care services. Of the 623 facilities offering delivery and newborn care services, 13.3% offered comprehensive emergency obstetric care (CEmONC), 19.6% provided basic emergency obstetric care (BEmONC) and 53.9% provided basic delivery and newborn service. The availability of essential equipment for delivery and newborn care was more than 80% in health facilities. Except for the coverage of vitamin K injection, the coverage of immediate newborn care was more than 85% in all health facilities. The coverage of use of chlorhexidine ointment to all newborns was more than 70% in government hospitals and primary health care centers (PHCCs) and only 32.3% in private hospitals.

Conclusions

These findings show gaps in equipment and drugs, especially in PHCCs and private health facilities. Improving readiness and availability of equipment and drugs in PHCCs and private health facility will help improve the quality of care to further reduce maternal and newborn mortality in Nepal.

Background

Almost all preventable neonatal deaths take place in low- and middle-income countries and affect the poorest who have the least access to high quality health services. Cost of health care is one of the factors preventing access to quality health services and universal health coverage. In Nepal, the majority of expenses related to newborn care are borne by the caregiver, regardless of socioeconomic status. We conducted a study to assess the out of pocket expenditure (OOPE) for sick newborn care in hospitals in Nepal.

Methods

This cross-sectional study of hospital care for newborns was conducted in 11 hospitals in Nepal and explored OOPE incurred by caregivers for sick newborn care. Data were collected from the caregivers of the sick newborn on the topics of cost of travel, accommodation, treatment (drugs, diagnosis) and documented on a sick newborn case record form.

Results

Data were collected from 814 caregivers. Cost of caregivers’ stay accounted for more than 40% of the OOPE for sick newborn care, followed by cost of travel, and the baby’s stay and treatment. The overall OOPE ranged from 13.6 to 226.1 US dollars (USD). The median OOPE was highest for preterm complications ($33.2 USD; CI 14.0–226.1), followed by hyperbilirubinemia ($31.9 USD; CI 14.0–60.7), respiratory distress syndrome ($26.9 USD; 15.3–121.5), neonatal sepsis ($ 25.8 USD; CI 13.6–139.8) and hypoxic ischemic encephalopathy ($23.4 USD; CI 13.6–97.7).

Discussion for practice

In Nepal, OOPE for sick newborn care in hospitals varied by neonatal morbidity and duration of stay. The largest proportion of OOPE were for accommodation and travel. Affordable and accessible health care will substantially reduce the OOPE for sick newborn care in hospitals.

Purpose: The aim of this study was to determine the repeatability of high‐ and low‐contrast visual acuity (VA) measurements at near. Methods: Fifty‐five normal subjects were recruited. Inclusion criteria included visual acuity of at least 0.00 logarithm of minimum angle of resolution (logMAR) on each eye at distance. One eye was selected for this study, either the one with a better acuity or randomly chosen if there was no difference between the two eyes. Near VA was measured in a random order with the PolyU high‐contrast (PolyU‐HC), the PolyU low‐contrast (PolyU‐LC), the Precision high‐contrast (P‐HC) and the Precision low‐contrast (P‐LC) charts at 400 mm. Measurements were repeated after one to two weeks. Repeatability was presented using the 95% limits of agreement between visits. Results: The between‐visit repeatability was ±0.063 logMAR for high‐contrast and ±0.141 for low‐contrast using the PolyU charts. The between‐visit repeatability was ±0.120 logMAR for high‐contrast and ±0.110 for low‐contrast using the Precision charts. Seventeen subjects had high‐contrast VA better than ‐0.10 logMAR using Precision chart, which could not be measured by PolyU chart. The mean difference between high‐ and low‐contrast VA was 0.108 from the Precision charts (median difference of 0.10 or one line). Conclusions: The Precision charts could measure high‐contrast near VA to threshold level. Practitioners should be aware of a VA difference of more than one line in repetitive measurement, at both high and low contrast. A difference in near high‐ and low‐contrast VA of more than one line may warrant further investigation.  相似文献

Background

The prevalence of Metabolic Syndrome and related chronic diseases, among them non-insulin-dependent (type 2) diabetes mellitus, are on the rise in the United States and throughout the world. Animal models that respond to environmental stressors, such as diet, are useful for investigating the outcome and development of these related diseases.

Objective

Within this context, growth and energy relationships were characterized in the Nile rat, an exotic African rodent, as a potential animal model for diet-induced type 2 diabetes mellitus and Metabolic Syndrome.

Methods

Compiled data from several studies established the relationship between age, body weight gain (including abdominal adiposity), food and water consumption, and blood glucose levels as determinants of diabetes in male and female Nile rats. Glucose Tolerance Testing, insulin, HbA1c, blood pressure measurements and plasma lipids further characterized the diabetes in relation to criteria of the Metabolic Syndrome, while diet modification with high-fat, low-fiber or food restriction attempted to modulate the disease.

Results

The Nile rat fed lab chow demonstrates signs of the Metabolic Syndrome that evolve into diet-induced non-insulin-dependent (type 2) diabetes mellitus characterized by hyperinsulinemia with rising blood glucose (insulin resistance), abdominal adiposity, and impaired glucose clearance that precedes increased food and water intake, as well as elevated HbA1c, marked elevation in plasma triglycerides and cholesterol, microalbuminuria, and hypertension. Males are more prone than females with rapid progression to diabetes depending on the challenge diet. In males diabetes segregated into early-onset and late-onset groups, the former related to more rapid growth and greater growth efficiency for the calories consumed. Interestingly, no correlation was found between blood glucose and body mass index (overall adiposity) in older male Nile rats in long term studies, whereas blood glucose and the perirenal fat pad, as well as liver and kidney weight, were positively related to early-onset diabetes. Rats weaned early (4-5 wks) and challenged with a high-fat Western-type diet developed diabetes faster, and body fat accumulation was more apparent, whereas food restriction curtailed it.

Conclusion

The Nile rat fed typical rodent diets develops hyperinsulinemia that precedes hyperglycemia (insulin resistance) leading to diet-induced type 2 diabetes associated with hypertriglyceridemia, hypercholesterolemia, and hypertension. Dietary modulation affected growth rate (weight gain and central adiposity) to impact disease progression. This rodent model represents a novel system of gene-diet interactions affecting energy utilization that can provide insight into the prevention and treatment of the type 2 diabetes and Metabolic Syndrome.  相似文献

Aseries of obtusatic acid analogues has been synthesized and evaluated as inhibitors of leukotriene B(4) (LTB(4)) biosynthesis and as antiproliferative agents. The 4-O-benzylated and the 4-O-demethylated congeners were the most potent inhibitors of LTB(4) production of the depside class of compounds, with IC(50) values in the submicromolar range. Furthermore, these compounds do not function as redox-based inhibitors because they were not reactive against a stable free radical, 2,2-diphenyl-1-picrylhydrazyl, and did not produce appreciable amounts of deoxyribose degradation as a measure of their potency to generate hydroxyl radicals. Some obtusatic acid congeners were also potent inhibitors of keratinocyte growth. Growth inhibition was not mediated by damage to the cell membrane, as the activity of lactate dehydrogenase released from the cytoplasm was in the control range.  相似文献

To test the ability of Gianturco expandable metallic stents to dilate and maintain patency in stenotic venae cavae, stenosis of the inferior vena cava was created in seven mongrel dogs by the percutaneous injection of absolute ethanol into the paravascular retroperitoneal space. Gianturco stents, placed across the stenotic segment, resulted in successful dilatation with improved hemodynamics in four dogs. The stents failed to dilate an occluded vena cava in one dog; in the remaining dogs, stent placement was complicated by early migration and occlusion. Gianturco stents were placed in two patients, one with superior vena cava syndrome and one with retroperitoneal fibrosis that obstructed the inferior vena cava, and resulted in immediate relief of presenting symptoms. These results should be viewed cautiously, but further investigation into the clinical use of the stents is indicated, especially for patients for whom other treatments are difficult.  相似文献
