Special needs of adolescent and young women in accessing reproductive health: promoting partnerships between young people and health care providers.

This article considers the unique challenges and opportunities that health care providers (HCPs) face when they address the sexual and reproductive health and rights of young women accessing services. Some of the difficulties that HCPs encounter in their work are highlighted, including poor remuneration, the impact of their personal biases and the effect of an under-equipped working environment. The financial, logistical and emotional challenges young people face in accessing services are also described, as well as some small changes that could promote fruitful partnerships between HCPs and their young clientele. Also considered is how international documents concerning reproductive health can be utilized as advocacy tools to ensure that, when governments speak of making young people's needs a priority, resources are also made a priority-so that reproductive health can become a reality for all young people.

Immunological responses to pneumococcal vaccine in frail older people

Advanced age has been associated with a wide range of defects in both the innate and adaptive immune systems including diminished specific antibody responses that increase the risk of invasive pneumococcal disease (IPD) and limit the effectiveness of vaccines. However, the elderly are a heterogeneous group and measures of overall frailty may be a better indicator of disease susceptibility (or vaccine response) than chronological age alone.

A literature review exploring how healthcare professionals contribute to the assessment and control of postoperative pain in older people

Little research has examined the care older people receive in the acute surgical setting. Although pain assessment and management are judged to be a priority in nursing, often pain, in older people, is undermanaged for a variety of reasons. Factors such as stoicism, communication and ageism can shape both the patients’ and nurses’ attitude towards the perception of pain which subsequently affects pain management. Through a review of the literature, this paper aims to: (i) identify how healthcare professionals contribute to the assessment and control of postoperative pain in older people and (ii) explore potential barriers to achieving more advantageous pain control in this group. It is suggested that to improve pain management there is a need to individualize pain assessment for older people and to assist clinicians with enhancing their education and decision‐making abilities in this field. This may best be achieved by supporting a programme of change to develop the skills of staff and encouraging learning through reflective practice. There is however a need for further research in this area.     

老年人肺功能与年龄增长的关系

目的: 探讨60岁以上老人动态肺功能随年龄增长的变化规律及机制.方法: 用日本PM-81型胸描仪对60岁以上老人动态肺功能的各项指标进行测量和分析.结果: 60岁以上老人动态肺功能各项指标均随年龄增加而降低,差异有高度显著性(P<0.01).结论: 60岁以上老人动态肺功能随年龄的增加而降低.其机制主要是呼吸中枢的功能降低,肺和胸廓的弹性阻力、呼吸道的非弹性阻力增加所致.     

A population-based study of repeat hospital admissions due to interpersonal violence for children aged 0–9 years

To assess the magnitude and nature of interpersonal violence resulting in hospitalisation of children and to identify subgroups at risk of repeat hospital admissions, a population-based, retrospective study of all violence hospitalisations in Western Australia for children aged 9 years or less was undertaken, using the 1990–2004 linked data retrieved from the Western Australian Mortality Database and the Hospital Morbidity Data System.
Of the 747 patients aged <10 years incurring 834 hospitalisations for the consequences of violence during the study period, 570 (76%) were less than 4 years of age. A total of 43 deaths from violence were recorded and 74 (9%) patients were admitted for more than one episode of violence. Victims aged 0–4 years from rural (hazard ratio [HR] = 2.72; 95% confidence interval [CI] 1.35, 5.43) and remote parts (HR = 2.79; 95% CI 1.25, 6.25) of the state were at increased risk of a subsequent admission for violence compared with those residing within the metropolitan area. Indigenous children aged 5–9 years were significantly more likely (HR = 3.57; 95% CI 1.14, 11.13) to incur a second hospitalisation for violence than their non-Indigenous counterparts. The identification of young victim subgroups at high risk of repeat hospitalisations is important for developing intervention strategies to reduce the burden of interpersonal violence. Young children aged 0–4 years living in rural and remote locations and Indigenous children aged 5–9 years should be specifically targeted for attention.
