Familial and socioeconomic influences on children''s well-being: An examination of preschool children in Kenya

As patterns of family formation change, it is important to know how children's lives are affected by their parents' marital and socioeconomic circumstances. Using data from the 1993 Kenya Demographic and Health Survey, this study shows that children of never married and formerly married mothers have significantly higher probabilities of polio dropout and acute undernutrition than those of monogamously married mothers. The number of male household members of working age greatly enhances the chances of full immunization and the nutritional status of children whose mothers were previously married. For children of never married mothers, the benefits of residing with males of working age are largely a function of ethnicity. The results also show that, although children are not disadvantaged nutritionally when their fathers have more than one wife, polygyny is associated with a higher probability of polio dropout and lower probability of full immunization than monogamy. Higher socioeconomic status is associated with a greater probability of full immunization and a lower probability of malnutrition but socioeconomic factors do not explain the effects of mothers' marital status. The findings underscore the complex realities of family interaction and the importance of the broader social context in accounting for variations in child welfare across diverse marital situations.     

Intravenous feeding with medium chain triglycerides. Effect on blood gases and the complement system in critically ill patients

Critically ill patients are usually in a catabolic state and may require total parenteral nutrition; this often includes lipid emulsions. Any adverse effects of constituents on pulmonary function, white cell function or the haemocoagulation system could have disastrous consequences in such patients. We have investigated the effects of a new intravenous lipid preparation containing medium chain triglycerides, which, in severely ill malnourished patients are theoretically a preferable energy source to conventional drug chain triglycerides. In a pilot study 17 critically ill patients whose lungs were artificially ventilated were given this lipid emulsion; no adverse effects were observed. Arterial oxygen and carbon dioxide tensions, ratio of inspired oxygen fractional concentration to arterial oxygen tension, platelet and white cell counts all remained constant and the complement system was not activated.     

针刺导管空肠造口术肠内营养在胰十二指肠切除术病人中的应用

目的探讨针刺导管空肠造口术(NCJ)肠内营养(EN)在胰十二指肠切除术病人中的应用效果。方法32例病人,16例术后肠外营养(PN)(对照组),16例术后行导管空肠造口术(NCJ)肠内营养(EN)治疗(实验组)。结果术后实验组的胃肠动力比对照组的恢复早(P<0.05)。治疗前两组病人血蛋白指标(白蛋白、前白蛋白、转铁蛋白)无明显差异。治疗后两组均升高,而实验组血蛋白指标的水平明显高于对照组(P<0.05),二者差异显著。结论导管空肠造口术(NCJ)肠内营养(EN)应用于胰十二指肠切除术病人中比肠外营养(PN)具有更多的优点。

Influence of individually estimated portion size on the assessment of nutritional risk in colorectal cancer in Portugal

We evaluated the influence of individually estimated portion sizes on the estimate of nutrient related risk of colorectal cancer, using data from a Portuguese hospital based case-control study on diet and colorectal cancer. A total of 100 patients with colorectal adenocarcinoma (aged 15-92 years) and 211 controls (aged 36-89 years) were included. Two data sets were created for nutrient analysis, the first one allowed estimates of food intake using data on portion size as collected with visual aids during the interview. The second estimate substituted respondents' estimate with a standard portion size, as used in the semi-quantitative (SQ) food frequency approach. The two analytic approaches yielded similar energy and nutrient intakes in cases and controls. The percent range of concordance is acceptable, in the same quartile varying from 44 to 82% (mean: 56%) and very good in the same or adjacent (+/-1) quartile (mean: 91%, range: 85-97%). The two estimates lead to a similar pattern of multivariate odd's ratio, however the SQ estimates resulted in more significant findings. We conclude that little extra information is gained by including individual portion size information when assessing diet-related risk of colorectal cancer.     

心理支持疗法对机械通气患者应激反应的影响

目的 观察心理支持疗法(PST)对ICU患者机械通气应激反应的影响。方法 将34例连续机械通气时间在20h的清醒患者，随机分为采用标准的PST方法进行治疗的观察组和对照组，观察焦虑抑郁程度和应激反应改变情况。结果 对照组患者的焦虑抑郁程度明显高于观察组，部分应激反应激素水平升高幅度也明显大于观察组。结论 PST可通过缓解机械通气患者的焦虑抑郁等不良情绪状态减轻机械通气带来的各种心身应激反应，有利于提高机械通气治疗的有效性和安全性。

Impact of early dietary gamma-linolenic acid supplementation on atopic eczema in infancy

Polyunsaturated fatty acids (PUFAs) are components of cell membranes and may play an immunomodulating role in the pathogenesis of atopic dermatitis (AD). The goal was to determine the impact of PUFAs on AD by dietary supplementation of infants. Based on the parents' decision on their babies' primary feeding, mothers and newborns were randomized to the supplementation with gamma-linolenic acid (GLA) or placebo for up to 6 months. Breastfed infants received GLA by supplementing their mothers. Formula diet was commercial whey hydrolysate unsupplemented with PUFAs. Of 131 eligible infants, 24 developed AD within the first year of life. Of these, nine belonged to the exclusively breastfed group (n = 58), 14 to the combined-fed group (n = 53), and one to the never breastfed group (n = 20). We could not find an influence of GLA on the development of AD. In subjects with AD, at 1 yr of age the serum-immunoglobulin E (IgE) was the lowest in the GLA-supplemented group A-subjects. In the GLA-supplemented group, GLA-levels in breast milk were similar in atopic and non-atopic infants. In the non-supplemented group the GLA-content of breast milk was 0.07% of total fatty acids in atopic infants vs. 0.17% in non-atopic infants (p < 0.01). Dietary GLA-supplementation could not prevent AD. Interestingly, the number of infants developing AD was the lowest in never breastfed children. In infants suffering from AD, GLA-supplementation seemed to reduce total IgE in the first year of life.

Le kiwi, votre partenaire santé

Résumé Le kiwi est par définition une baie : il possède un grand nombre de graines incluses dans une chair comestible. Le kiwi a pour nom latinActinidia et il y a principalement deux espèces d’Actinidia :Actinidia chinensis etActinidia deliciosa. Le kiwi n’est pas seulement un fruit agréable à manger, il est aussi une source exceptionnellement riche en diverses vitamines. Le kiwi est notamment très riche en vitamine C puisqu’il en contient 50 % plus qu’une orange. Le kiwi contient aussi des vitamines K et E. Il est également une source non négligeable de potassium et de folate. Il contient aussi un laxatif, qui plus est, puissant. La qualité nutritionnelle du kiwi ne s’altère pas même pendant une longue durée de stockage pour certains nutriments. Cependant, les risques de réponse allergique ne doivent pas être sous-estimés. The kiwifruit is, by definition, a berry: it has a large number of seeds embedded in fleshy, edible tissue. The Latin name of kiwifruit isActinidia and there are two main species ofActinidia that are commercially important:Actinidia chinensis andActinidia deliciosa. Kiwifruit are not only enjoyable to eat. They are exceptionally good sources of vitamin C and they are also excellent sources of potassium and folate and possibly of vitamin E and vitamin K. They contain a most effective laxative. There is very little, if any, loss of nutritional quality during storage. However, the risks from the allergic response to kiwifruit should not be underestimated.
