Physical activity brings significant health benefits to middle-aged adults, although the research to date has been focused on late adulthood. This study aims to examine how ageing affects the self-reported and accelerometer-derived measures of physical activity levels in middle-aged adults. We employed the data recorded in the UK Biobank and analysed the physical activity levels of 2,998 participants (1381 men and 1617 women), based on self-completion questionnaire and accelerometry measurement of physical activity. We also assessed the musculoskeletal health of the participants using the dual-energy X-ray absorptiometry (DXA) measurements provided by the UK Biobank. Participants were categorised into three groups according to their age: group I younger middle-aged (40 to 49 years), group II older middle-aged (50 to 59 years), and group III oldest middle-aged (60 to 69 years). Self-reported physical activity level increased with age and was the highest in group III, followed by group II and I (P?<?0.05). On the contrary, physical activity measured by accelerometry decreased significantly with age from group I to III (P?<?0.05), and the same pertained to the measurements of musculoskeletal health (P?<?0.05). It was also shown that middle-aged adults mostly engaged in low and moderate intensity activities. The opposing trends of the self-reported and measured physical activity levels may suggest that middle-aged adults over-report their activity level as they age. They should be aware of the difference between their perceived and actual physical activity levels, and objective measures would be useful to prevent the decline in musculoskeletal health.
Comprehensive evidence regarding the treatment of non-anaemic iron deficiency in patients undergoing valvular heart surgery is lacking. This study aimed to investigate the association between non-anaemic iron deficiency and postoperative outcomes in these patients. We retrospectively analysed 321 patients of which 180 (56%) had iron deficiency (defined as serum ferritin < 100 ng.ml-1 or < 300 ng.ml-1 with transferrin saturation < 20%). While the iron-deficient group had lower pre-operative haemoglobin levels than the non-iron deficient group (median (IQR [range]) 134 (127–141 [120–172]) g.l-1, 143 (133–150 [120–179]) g.l-1, p = 0.001), there was no between-group difference in allogeneic red blood cell transfusion. Median (IQR [range]) days alive and out of hospital at postoperative day 90 was 1 day shorter in the iron-deficient group (80 (77–82 [9–85]) days vs. 81 (79–83 [0–85]) days, p = 0.026). In multivariable analysis, only cardiopulmonary bypass duration (p = 0.032) and intra-operative allogeneic red blood cell transfusion (p = 0.011) were significantly associated with reduced days alive and out of hospital at postoperative day 90. Iron deficiency did not exert any adverse influence on secondary outcomes except length of hospital stay. Our findings indicate that non-anaemic iron deficiency alone is not associated with adverse effects in patients undergoing valvular heart surgery when it does not translate into an increased risk of allogeneic transfusion. 相似文献
目的 系统评价益气活血法联合西药治疗特发性肺纤维化(idiopathic pulmonary fibrosis,IPF)的疗效及安全性。方法 系统检索中国知网、维普网、万方数据库、EMbase、PubMed、Cochrane Library图书馆等数据库,检索时限从数据库建库至2021年1月,纳入益气活血法联合西药治疗特发性肺纤维化的随机对照试验(randomized controlled trial,RCT),由2名研究人员独立筛选并交叉核对纳入结果,提取有效数据后,应用RevMan 5.3软件进行Meta分析。结果 纳入16项随机对照试验共计1160例IPF患者。分析结果显示益气活血法联合西药组可提高临床总有效率(OR= 3.71,95% CI [2.68,5.14],P<0.00001);改善患者肺功能:用力肺活量(MD=0.31,95% CI [0.23,0.38],P<0.00001)(MD=3.59,95% CI [1.51,5.66],P=0.0007),一氧化碳弥散量(MD=2.54,95% CI [1.83,3.25],P<0.00001);提高生活质量,降低圣乔治评分:呼吸困难(MD=-12.70,95% CI [-21.07,-4.32],P=0.003),活动能力(MD=-8.38,95% CI [-13.66,-3.10],P=0.002),疾病影响(MD=-13.87,95% CI [-22.53,-5.22],P=0.002);并可降低患者中医症状积分:喘息(MD=-0.66,95% CI [-0.84,-0.49],P<0.00001),咳嗽(MD=-0.71,95% CI [-1.04,-0.37],P<0.0001);有效提高动脉血氧分压(MD=5.92,95% CI [4.61,7.22],P<0.00001);且不增加不良事件发生率(OR=0.55,95% CI [0.27,1.14],P=0.11)。结论 益气活血法联合西药治疗IPF可提高临床治疗有效率,改善患者生活质量,且不增加临床不良事件(便秘、嗜睡、口干、恶心呕吐、皮肤瘙痒、腹泻等)发生率。但本研究纳入文献质量参差不齐,仍需更多大样本、高质量、多中心的RCT试验验证结论。 相似文献
