Quality of life four years after acute myocardial infarction: short form 36 scores compared with a normal population

OBJECTIVES: To assess the impact of myocardial infarction on quality of life in four year survivors compared to data from "community norms", and to determine factors associated with a poor quality of life. DESIGN: Cohort study based on the Nottingham heart attack register. SETTING: Two district general hospitals serving a defined urban/rural population. SUBJECTS: All patients admitted with acute myocardial infarction during 1992 and alive at a median of four years. MAIN OUTCOME MEASURES: Short form 36 (SF 36) domain and overall scores. RESULTS: Of 900 patients with an acute myocardial infarction in 1992, there were 476 patients alive and capable of responding to a questionnaire in 1997. The response rate was 424 (89. 1%). Compared to age and sex adjusted normative data, patients aged under 65 years exhibited impairment in all eight domains, the largest differences being in physical functioning (mean difference 20 points), role physical (mean difference 23 points), and general health (mean difference 19 points). In patients over 65 years mean domain scores were similar to community norms. Multiple regression analysis revealed that impaired quality of life was closely associated with inability to return to work through ill health, a need for coronary revascularisation, the use of anxiolytics, hypnotics or inhalers, the need for two or more angina drugs, a frequency of chest pain one or more times per week, and a Rose dyspnoea score of >/= 2. CONCLUSIONS: The SF 36 provides valuable additional information for the practising clinician. Compared to community norms the greatest impact on quality of life is seen in patients of working age. Impaired quality of life was reported by patients unfit for work, those with angina and dyspnoea, patients with coexistent lung disease, and those with anxiety and sleep disturbances. Improving quality of life after myocardial infarction remains a challenge for physicians.

Carer Knowledge and Perceptions of Healthy Lifestyles for Adults with Intellectual Disabilities

Background Carers can have a significant impact supporting people with intellectual disabilities to make healthy lifestyle choices. This study examines carers’ training needs on diet and physical activity. Methods A cross‐sectional survey was undertaken of the knowledge and perceptions of carers supporting adults with intellectual disabilities. An interviewer administered questionnaire was used to examine carer knowledge of public health recommendations on diet and physical activity; perceptions of the benefits of healthy diets and physical activity levels; and the carer views on the barriers to change experienced by individuals with intellectual disabilities. Results Sixty‐three carers took part in the study. They generally had a low level of knowledge around public health recommendations on diet and physical activity. Greater importance was attributed to the health benefits of diet than physical activity. Carers rated intrapersonal barriers to change within the person with intellectual disabilities as more important, than interpersonal or external barriers to change, with significant differences in perceived barriers relevant to diet and physical activity. Conclusions Carers supporting adults with intellectual disabilities have significant training needs relevant to promoting healthy lifestyles. This highlights the opportunity to promote health improvement via the development, and provision, of effective training initiatives.     

Structure–activity relationship of truncated and substituted analogues of the intracellular delivery vector Penetratin

Abstract: Peptides derived from the third α‐helix of the homeodomain (residues 43–58; Penetratin) of Antennapedia, a Drosophila homeoprotein, were prepared by simultaneous multiple synthesis. Sets of N‐ and C‐terminally truncated peptides, as well as a series of alanine substitution analogues, were studied. Cell penetration assays using human cell cultures with these peptides revealed that the C‐terminal segment ⁵²Arg‐Arg‐Met‐Lys‐Trp‐Lys‐Lys⁵⁸ of the parent sequence was necessary and sufficient for efficient cell membrane translocation. Individual Ala substitutions of the peptide’s basic residues led to markedly decreased cell internalization ability, whereas replacement of hydrophobic residues was tolerated surprisingly well. Subcellular localization was seen to be affected by substitutions, with analogues being addressed preferentially to the cytosol or to the nucleus. Conformational constriction of the Penetratin sequence through placement and oxidation of flanking cysteine residues afforded a cyclic disulfide peptide which had lost most of its membrane translocation capacity.     

蒙药如达溃疡散对大鼠乙酸性胃溃疡及其血清促胃液素的影响

目的:探讨如达溃疡散对大鼠乙酸性胃溃疡的作用及对其血清促胃液素(gastrin)含量的影响.方法:采用乙酸法复制胃溃疡模型,将大鼠随机分为对照组、如达溃疡散组、雷尼替丁组,观察如达溃疡散对大鼠胃溃疡的作用,并检测其对大鼠血清中促胃液素含量的影响.结果:与对照组相比,如达溃疡散能明显抑制溃疡的发生,抑制血清促胃液素含量.结论:如达溃疡散具有抗胃溃疡的作用,其作用机理可能是通过抑制促胃液素释放,进一步减少胃酸分泌来实现的.
