Summary Objectives: Assessment of the literature on the length of maternity leaves and health of mothers and children; evaluation of the Swiss situation in view of the maternity leave policy implemented in 2005. Methods: Review of thirteen original studies identified by PubMed using topic-related terms. Results: A positive association was shown between the length of maternity leave and mother’s mental health and duration of breastfeeding. Extended maternity leaves were also associated with lower perinatal, neonatal and post-neonatal mortality rates as well as lower child mortality; however, results are obtained in ecological studies. There is less evidence regarding other health outcomes. The new policy in Switzerland extends maternity leave for a considerable number of women to 14 weeks. With this prolongation, fewer depressive symptoms and longer breastfeeding duration can be expected, while benefits regarding other health outcomes would warrant longer leaves. Conclusions: Longer maternity leaves are likely to produce health benefits. The new policy in Switzerland will probably improve the situation of those women, who previously were granted only minimal leave and/or mothers with additional social risk factors. Submitted: 21 October 2005; Revised: 10 October 2006; Accepted: 5 December 2006  相似文献

We know little about older adults' use of online and offline health information sources for medical decision making despite increasing numbers of older adults who report using the Internet for health information to aid in patient–provider communication and medical decision making. Therefore we investigated older adult users and nonusers of online and offline sources of health information and factors related to medical decision making. Survey research was conducted using random digit dialing of Florida residents' landline telephones. The Decision Self-Efficacy Scale and the Reliance Scale were used to measure relationships between users and nonusers of online health information. Study respondents were 225 older adults (age range = 50?92 years, M = 68.9, SD = 10.4), which included users (n = 105) and nonusers (n = 119) of online health information. Users and nonusers differed in frequency and types of health sources sought. Users of online health information preferred a self-reliant approach and nonusers of online health information preferred a physician-reliant approach to involvement in medical decisions on the Reliance Scale. This study found significant differences between older adult users and nonusers of online and offline sources of health information and examined factors related to online health information engagement for medical decision making.  相似文献

NO one has so far produced anything approaching a clear picture of either fat or carbohydrate metabolism and the interactions of the two are still more involved and elusive although they clearly exist. Plants and animals build up reserves of fat from carbohydrate, but the reverse process (fat into carbohydrate), proved in plant seeds, is still unproven in animals, although theoretically possible.In normal human metabolism fat-carbohydrate interactions are almost hidden. The disturbances shown in the metabolism of a diabetic seem to give us the clearest indications of these interactions. Either carbohydrate or fat can be used as the main source of body fuel, but their metabolic course is very different, both as regards chemistry and function. It is only whep carbohydrate is not available, either in starvation or severe diabetes, that fat provides the fuel of the body; this contrast is also manifest in the blood and internal organs, especially the liver. Under the commonest normal conditions of diet carbohydrate is predominantly and preferentially used for metabolism. The liver is rich in glycogen, poor in fat; the blood fat is minimal and ketone bodies, although perhaps present in small amount in the blood at most times, are absent on common tests. As soon as carbohydrate is insufficiently available for the needs of metabolism, depot fat flows to the liver and is there catabolized to ketone bodies which recent proof has shown to be burned peripherally in the muscles independent of carbohydrate metabolism. This is a normal process, harmful only in diabetes, and especially harmful when it occurs suddenly, e.g. when insulin is cut off from a fat diabetic dog or human patient. A diabetic supports with ease a prolonged severe ketosis but suffers from one of sudden onset, although of milder severity. Insulin in the diabetic and sugar in the starved switches metabolism from fat to carbohydrate usage very quickly and ketonuria usually disappears in three to six hours.“Diabetic obesity” is very common and is often seen in the earliest stages and again after insulin treatment. It seems probable that hyperglycæmia causes this obesity and this has been clearly established by observations on an unusual case of lipæmia, diabetes and lipodystrophy.Lipæcmia may occur in two opposite phases of metabolism, one anabolic—when fat is on its way to storage, the other catabolic—when it is flowing from stores to the liver. The latter is the usual condition obvious in disease.Work has also been done which suggests that other lipotropic factors—choline, lipocaic, &c., exert an influence on carbohydrate-fat balance, more specifically the glycogen-fat balance in the liver.In America attention has been drawn to the frequent and persistenzt occurrence of fatty enlargement of the liver in diabetic children. The author has seen many diabetic children (usually in a state of chronic ketosis) with enlarged livers, but such enlargement has rapidly disappeared with better management of the diabetes. Only two out of some 500 diabetic children have clearly shown the unmistakable syndrome of “hepatomegalic dwarfism ”. In these two cases choline and lipocaic were given over prolonged periods without any effect: the liver, however, of one of these cases has since become normal by the addition of zinc protamine insulin.  相似文献

The in vivo and in vitro effects of 4,5-diphenylimidazole-2-thione (1), 4,5-diphenyl-1,2,4-triazole-3-thiol (2) and 5-(2-hydroxyphenyl)-4-phenyl-1,2,4-triazole-3-thiol (3) on α-glucosidase and α-amylase were investigated. The in vivo inhibition has been found to be dose-dependent and to occur at a value less than LD50. The in vitro treatment of the enzymes by 4,5-diphenylimidazole-2-thione exhibited a reversible inhibition of the non-competitive type with Ki value of 3.5 and 6.5×10(-5) M for α-glucosidase and α-amylase, respectively. 4,5-diphenyl-1,2,4-triazole-3-thione showed a reversible inhibition of the competitive and non-competitive types, with Ki value of 10(-5) M magnitude, for α-glucosidase and α-amylase. On the other hand, 5-(o-hydroxyphenyl)-4-phenyl-1,2,4-triazole-3-thione did not display an inhibitory effect towards α-amylase but showed a potent inhibition of the competitive type for hepatic α-glucosidase with 10(-5) M magnitude of Ki value.  相似文献

Fetal alcohol exposure (FAE) produces profound alterations in immunological and neuroendocrine functions. The present study examined the effects of FAE on the secretion of tumor necrosis factor (TNF-α) and corticosterone following administration of lipopolysaccharide (LPS) in normal (N) adult rats, in adult offspring of dams fed a liquid diet supplemented with ethanol (E), and in pair-fed control offspring (P). LPS-induced TNF-α secretion was not affected by either gender or prenatal treatment. In contrast, LPS-induced corticosterone secretion was significantly greater in female than in male rats, and at 60-min post-LPS was significantly higher in E and P, compared to N females. Ovariectomy significantly inhibited LPS-induced TNF-α secretion in E, but not in P and N, rats and chronic replacement with 17-β-estradiol markedly inhibited TNF-α secretion in ovariectomized E and N, but not in P, rats. In contrast, ovariectomy reduced the effects of LPS on corticosterone secretion in all groups, and chronic replacement with 17-β-estradiol reversed this effect. These findings indicate that LPS-induced secretion of corticosterone, but not TNF-α, is affected by prenatal manipulations and by gender. In addition, alterations in the hormonal environment in females modulate LPS-induced corticosterone secretion in all prenatal treatment groups, but differentially influence TNF-α secretion in rats exposed to alcohol, restricted feeding, or normal diets in utero.  相似文献

The aim of this study was to develop and validate a semiquantitative food frequency questionnaire to classify individuals according to their intakes of retinol and β‐carotene. Food items for the questionnaire were selected both on the basis of their contribution to total population intake of retinol and β‐carotene and on the proportion of between‐person variation explained, which was as calculated from data of two study populations in the Netherlands. Thus, 15 products containing retinol and 15 products containing β‐carotene were selected. These contributed over 90% to the total intake and explained 99% of the variation of retinol and β‐carotene, respectively. The questionnaire was validated against a dietary history in a population of 82 women (aged 30–49 years). The time elapsed between the two interviews was (on average) 25 days. Spearman rank‐order correlation coefficients comparing the questionnaire with the dietary history were 054, 0.59, and 0.64 for retinol, β‐carotene, and total vitamin A, respectively. The proportion of exact agreement in the two extreme categories of vitamin A intake, based on quintiles, was 56%. The corresponding gross misclassification (from 1 extreme category into the opposite) was 3%. These data indicate that a very short questionnaire can classify subjects into categories according to their vitamin A intake.  相似文献

Cuprimine? and Syprine? are therapeutics approved by the USFDA to treat copper overload in Wilson Disease (a genetic defect in copper transport) by chelation and accelerated excretion of internally-deposited copper. These oral therapeutics are based on the respective active ingredients D-penicillamine (DPA) and N,N'-bis (2-aminoethyl) -1,2-ethanediamine dihydrochloride (Trien). Cuprimine is considered the primary treatment, although physicians are increasingly turning to Syprine as a first-line therapy. Both drugs exhibit oral systemic activity and low toxicity; their biological effects and safety are established. Previous in vivo studies using a rodent animal model established the decorporation potential of Cuprimine and Syprine for (60)Co and (210)Po. Currently these studies are being expanded to evaluate the in vivo decorporation efficacy of these drugs for several additional radionuclides. In this report, results of this investigation are discussed using the radionuclides (137)Cs, (60)Co, (192)Ir and (85)Sr. Short-term 48-h pilot studies were undertaken to evaluate DPA and Trien for their in vivo decorporation potential using male Wistar-Han rats. In these studies, a radionuclide solution was administered to the animals by intravenous (IV) injection, followed by a single IV dose of either DPA or Trien. Control animals received the radionuclide alone. Results show effective decorporation of (60)Co by DPA within the time frame evaluated. DPA and Trien were also modestly effective in decorporation of (137)Cs and (85)Sr, respectively. The study did not find DPA or Trien effective for decorporation of (192)Ir. Based on these encouraging findings, further studies to evaluate the dose-response profiles and timing of the chelator administration post exposure to radionuclides are warranted.  相似文献

This article explores the current state of the law governing partnerships and other collaborations between tax-exempt health care organizations and private health care providers. The author sets out the regulatory maze through which exempt entities and private parties must navigate in attempting to maintain Internal Revenue Code (IRC) Section 501(c)(3) status for the exempt entity in these relationships. The article discusses and comments on general principles through an examination of case law, statutes, regulations, revenue rulings, revenue procedures, and information letters, as well as state law issues, with an emphasis on maintaining charitable purposes, effecting control, and dealing with ownership and compensation issues.  相似文献

BACKGROUND: It has been suggested that high unemployment rates in society may be less harmful to the health of people than low unemployment rates. Therefore, a study was carried out to compare, among young men and women, the relationship between health and long-term unemployment during periods of rapid economic growth 'boom' and economic recession. METHODS: Two study groups were chosen at age 21 y (5 y after compulsory schooling ended) from an industrial town in northern Sweden. The first group (number 1083) was chosen and surveyed in 1986 (under 'boom' conditions); the second (number 898) was chosen in 1994 (under economic recession conditions). The non-response rate was 2% for the boom group and 10% for the recession group. The main outcome measurements examined were somatic and psychological symptoms. RESULTS: Health criteria for general health among long-term unemployed young men and women did not differ between the group surveyed in boom conditions and the group surveyed in recession conditions. The only exception was for psychological symptoms, which scored lower among the men in the recession group. Individual unemployment had a high explanatory power for poor health, in particular, psychological ill health. CONCLUSIONS: When comparing periods of boom and recession there was no difference in somatic and psychological symptoms for those who were long-term unemployed. Thus, the trade cycle appeared to have had no impact on their health.  相似文献

Systematic investigations of food availability, dietary patterns, nutritional levels, were initiated among aboriginal tribes in different regions in India. These studies also compared nutritional intakes to the physiological requirement of the groups as well as the influence of respective dietaries on physique, working efficiency and growth of children. The 31 tribes investigated were located in the North‐Eastern Frontier, Eastern India, the Central region, Southern states and Andaman and Nicobar islands. Samples of food and homely brewed alcoholic beverages collected during the investigation were analysed for nutrient content.

The investigations provided considerable information on living conditions. A comparative study of family size, total food intakes, supplies of food energy, proteins, minerals and vitamins as well as correlations between dietary patterns and growth of children and Korperfulle index of body build revealed that 14 tribes (47 percent) were well fed and in satisfactory nutritional status, eight (23 percent) were underfed and deficient in many nutrients. Nine tribes (30 percent) lived in utmost poverty and were grossly deficient in all the nutrients and were in a state of physical degeneration and nutritional depletion. This may also be the reason for the degeneration, depletion and ultimate extinction of many regional tribes of India.  相似文献

Background

In Benin, malaria was the leading cause of hospital consultation for children less than 5 years old (47.2%), and for all patients not hospitalized (42.3%). Its incidence among those who attended a health facility was respectively 42.9% and 17%. To address this problem, the National Program for the Fight against Malaria undertook, in 2011, a mass campaign of distribution of Long-Lasting Insecticidal Nets (LLINs). In addition to this strategy, the program decided to implement Indoor Residual Spraying in 7 of the 9 municipalities of Atacora department, which is one of the most malaria endemic areas. The objective of this study was to see if adding the IRS to the LLINs (municipality of Kouandé) strategy is cost-effective, as compared to the LLINs-only strategy (municipality of Copargo), in highly malaria endemic areas.

Method

This study was a cross-sectional study of the implementation of the IRS from June 2011 to July 2011. Regarding the selection of health workers, managers of the malaria program, and partners of implementation of the IRS, a reasoned choice was made. The data collection consisted mainly of a series of interviews with people responsible for resource management and the exploitation of documents provided by them.

Results

After the implementation of LLNs + IRS the annual incidence of malaria in health facilities decreased significantly at Kouandé-Centre and at Guilmaro. In the same period it increased significantly at Copargo- Centre, and decreased at Pabégou.The average cost per malaria case prevented (CE) was respectively 85,572.4 FCFA at Copargo Centre, 38,932.6 FCFA at Kouandé Centre, 15,940.6 FCFA at Pabégou and 174,728.5 FCFA at Guilmaro. According to the results, the CE ratio at Kouandé-Centre is lower than the CE ratio at Copargo- Centre and the CE ratio at Guilmaro is higher than the CE ratio at Pabégou.The LLINs?+?IRS strategy is more cost effective in urban areas than the LLINs-only strategy. The opposite result is observed in rural areas.

Conclusion

The LLINs?+?IRS strategy is cost effective in highly endemic areas both urban and rural, if communities sleep in sprayed structures and use LLINs even when it is hot.

With the growing problem of childhood obesity, recent research has begun to focus on family and social influences on children’s eating patterns. Research has demonstrated that children’s eating patterns are strongly influenced by characteristics of both the physical and social environment. With regard to the physical environment, children are more likely to eat foods that are available and easily accessible, and they tend to eat greater quantities when larger portions are provided. Additionally, characteristics of the social environment, including various socioeconomic and sociocultural factors such as parents’ education, time constraints, and ethnicity influence the types of foods children eat. Mealtime structure is also an important factor related to children’s eating patterns. Mealtime structure includes social and physical characteristics of mealtimes including whether families eat together, TV-viewing during meals, and the source of foods (e.g., restaurants, schools). Parents also play a direct role in children’s eating patterns through their behaviors, attitudes, and feeding styles. Interventions aimed at improving children’s nutrition need to address the variety of social and physical factors that influence children’s eating patterns.  相似文献

Background Roma are Europe’s largest minority population. Serbia and Macedonia have the greatest proportion of Roma outside of the European Union. Our objective was to examine women’s agency and how it related to desired timing of pregnancy among Romani women in Macedonia and Serbia. Methods We surveyed 410 Romani women who had given birth in the last 2 years between November 2012–February 2013 in Serbia and Macedonia using purposeful snowball sampling. Log-Poisson models were used to examine the association between women’s inclusion in healthcare decision- making and desired timing of pregnancy. Results Romani women in Macedonia and Serbia were excluded from the labor market, with over 80% being unemployed, approximately 30% had no schooling, and 17% were not included in healthcare decisions. Romani women who were sole decision-makers in relation to their health were 1.4 times more likely to desire the timing of their most recent pregnancy [RRR?=?1.4, CI (1.1, 1.8)]. Conclusions Romani women who have great involvement in their own healthcare decisions were more likely to desire the timing of their current pregnancy. Women’s inclusion in such important decisions is important and empowerment programs that address gender inequity are needed in Romani communities, particularly for control of timing of pregnancy.  相似文献
