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。

The influence of white matter lesions on neuropsychological functioning in demented and non-demented 85-year-olds

White matter lesions on computed tomography of the head were studied in relation to neuropsychological functioning in subjects from a representative sample of non-demented ( n = 134) and demented ( n = 98) 85-year-olds. Non-demented subjects with white matter lesions ( n = 46) scored significantly lower in tests of verbal ability (Synonyms), spatial ability (Block Design, Clock Test), perceptual speed (Identical forms), secondary memory (Thurstone Picture Memory), basic arithmetic (Coin Test) and the global cognitive screening test Mini-Mental State Examination than non-demented subjects without white matter lesions ( n = 88). Demented subjects with white matter lesions ( n = 67) scored significantly lower in tests of spatial ability (Block Design and Clock Test) and secondary memory (free recall in the MIR memory test, Ten-word memory test I and II) and in the Mini-Mental State Examination than demented subjects without white matter lesions ( n = 31). It is concluded that white matter lesions contribute to cognitive decline in both non-demented and demented elderly subjects.     

四川省绵阳市2019—2021年流行性感冒流行病学特征分析

目的 了解绵阳市2019—2021年流行性感冒流行病学特征,为绵阳市流感防控工作提供重要依据。方法 收集绵阳市2019—2021年流感监测相关数据,采用描述性流行病学方法进行统计学分析。结果 绵阳市2019—2021年流感共报告发病55 970例,年均报告发病率388.08/10万。报告流感样病例（influenza-like illness cases, ILI） 103 723例,年平均ILI%为3.58%。2019年流感报告发病率、ILI%、阳性检出率均远超过历年同期水平。人群分类构成以15岁以下学生为主。报告发病数居前三位的地区分别为涪城区20 118例（占35.94%）、游仙区6 394例（占11.42%）、江油市5 800例（占10.36%）。2019—2021年共收到并检测ILI标本10 126份,阳性率19.53%;标本阳性检出率以15岁以下学生为主。历年流感病毒优势毒株呈现出交替流行的趋势,2019年以A（H3）型为主,2020年受新冠疫情影响,全年阳性检出率均较低,2021年除检出2份A（H9）型外,其余均为BV型。2019—2021年共报告ILI暴发疫情43起,发生时间主要集中在冬季,场所以小学居多。结论 2019—2021年绵阳市流感病例、ILI、病原学监测、暴发疫情的特征基本一致,15岁以下的学生及学校仍为重点关注人群及场所。而新型冠状病毒肺炎疫情大流行下,流感的低发水平进一步印证非药物干预措施对流感防控工作的重要性。     

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.

Influence of epidemiological factors on blood transfusion

The prevalence, incidence and risk factors of infectious diseases observed in the general population have been described to directly influence transfusion medicine, especially the blood selection. The objective is to ensure the blood safety. The characterization of modes of transmission influences the donor selection: the risk factors of the main blood‐borne infections have permitted to adapt the pre‐donation questionnaire in order to exclude at‐risk donors. The prevalence of infections also has an impact on the blood screening strategy. For example, anti‐HBc antibody (Ab) screening is currently performed only in countries where the HBV prevalence is compatible with a reasonable number of donor exclusions. HTLV Ab screening is implemented in countries in which the rate of donors originating from endemic areas could represent a risk for blood components. Measurement of incidence which contributes to the residual risk has led to the introduction of nucleic acid testing (NAT) for HIV, HCV and in some cases for HBV in viral screening strategy in many countries worldwide. The observed NAT yield differs according to the incidence of the infection and according to the country. Finally, the putative blood transmission of new and emerging pathogens has led to implement specific and non‐specific measures in order to enhance blood safety. Conversely, although the blood donor population is selected, the data observed in this population have also contributed to better understand epidemiology and pathogenesis of infection. Moreover, owing to the recent progress in developing modelling approaches for estimating risk, we are able to anticipate a transfusion transmission threat by introducing, when necessary, specific measures intended for reduce this risk.
