呼和浩特地区11070名中,小学生视力调查分析

本文共测试了１１０７０名呼和浩特市城区和在区中、小学生的视力。结果是：引起学生视力低下的主要原因为近视，且近视的检出率和重度近视随年龄增长而增加，特别是在１３～１８岁年龄组更为明显；近视检出率城区学生明显高于农区学生（μ＞２．５８，ｐ＜０．０１），但是，无论城区学生或农区学生，女生的检出率分别都明显高于男生（μ＞２．５８，Ｐ＜０．０１）。     

老年病人鼻饲营养调查

对11名69～83岁不能自然进食的男性鼻饲病人进行了全面的营养调查,平均每人每日热能摄取为1722kcal,而热能消耗在1300～1700kcal之间。蛋白质、脂肪和碳水化物每人每日平均摄入82.4、72.5、185.0g,分别占总产热量19.1、37.9、和43.0％。动物蛋白质和动物脂肪分别占总蛋白和总脂肪的71.9和69.3％,蛋白质量较优。脂肪总量虽不太高,但占总产热量偏大,碳水化物嫌少,而(?)(?)(?)投入939mg,摄入过多。钙、磷、铁摄入充裕,可满足需要。维生素A、核黄素也可满足需要,但硫胺素、尼克酸和抗坏血酸摄入量不足。这些都还需要改进。

Attitudes toward male fertility control: results of a multinational survey on four continents

BACKGROUND: Following extensive research activity to develop an effective agent to control male fertility, such a product may be available for use within approximately 5 years. However, little is known concerning contraceptive knowledge, desires and attitudes of men in different countries, and their acceptance of male fertility control (MFC). METHODS: A survey of >9000 males aged 18-50 years was performed in nine countries on four continents in 2002. The objective was to compare, on a cross-cultural basis, the knowledge, attitudes and acceptability of MFC among men and assess their willingness to use such a method. RESULTS: Between 50 and 83% of the male respondents currently use contraceptive methods, and 55-81.5% reported that both partners participate in selecting the method of contraception employed. Overall acceptance of hormonal MFC was high (>55%), with 28.5-71.4% of survey participants of various nationalities expressing the willingness to use such a method. CONCLUSION: While MFC appears to be well accepted overall, the willingness to use this type of contraception varies widely between differing population groups. The specific characteristics and profile of any MFC product will have to be carefully evaluated to accurately assess its acceptance, both by men and their female partners.     

Comparison of dietary intakes in four selected European populations

Summary The composition of diet and food intakes in four selected European populations were compared. Dietary data (from the World Health Organization Project on Monitoring Trends and Determinants in Cardiovascular Disease) were measured by record methods and were available for middle-aged men in Finland (n = 653), France (n =1128), Northern Ireland (n = 356), and southern Germany (Augsburg region; n = 899). Nutritional variables — which are independent of the absolute energy intake, such as the percentage supply of energy from macronutrients and the ratio of polyunsaturated to saturated fatty acids — were on the whole similar. However, striking differences were found in food intake and in the percentage supply of fat from different foods. The results indicate that detailed knowledge of consumption figures is necessary to develop prudent and acceptable nutrition intervention programs.Abbreviations CHD coronary heart disease - MONICA monitoring trends and determinants in cardiovascular disease - MUFA monounsaturated fatty acids - P/S ratio ratio of polyunsaturated fatty acids/saturated fatty acids - PUFA polyunsaturated fatty acids - SFA saturated fatty acids     

CR-lipped bearing is an adequate functional solution to patients with perioperative excessive laxity in cruciate retaining total knee arthroplasty

BackgroundThe cruciate retaining lipped (CR-lipped) bearing is designed to provide more anterior-posterior (AP) stability and could be employed to resolve excessive intraoperative laxity during the cruciate retaining TKA (CR-TKA). The aim of the study was to determine whether the CR-lipped bearing in CR-TKAs with a perioperative excessive laxity allows equivalent functional results as compared to the standard CR articulation.MethodsA cohort of 111 TKAs with CR-lipped bearings was matched to a cohort of conventional CR bearings regarding age and sex. The CR-lipped bearing was used in patients with excessive knee AP laxity and the regular CR bearing was used in patients without excessive AP laxity during TKA. Various PROMs (WOMAC, KSS, SF-36) were assessed preoperatively and at 5-years postoperative in combination with revision rate and Range of Motion (ROM).ResultsPROMs did not differ significantly between both groups 5-years postoperatively. Mean ROM (flexion) 5-years postoperatively was not significantly different. The implant survivorship was 100% for both cohorts with revision for any reason as end point.ConclusionBased on these results, the CR-lipped bearing is a safe and effective solution for mild interoperatively assessed PCL laxity during CR-TKA without loss of function or decreased survivorship at 5 years. Peroperative conversion to a PS-TKA in order to obtain satisfactory functional scores might therefore not be necessary when mild PCL laxity is observed during surgery. Further research should focus on verifying this approach and longer follow-up is needed to generate data on long term survivorship.Level of evidenceLevel IV therapeutic, retrospective, cohort study.
