ABSTRACT

Increased incidences of childhood acute leukaemia were noted among survivors of the atomic bombings of Hiroshima and Nagasaki. In Western societies, Childhood Acute Lymphoblastic Leukaemia has a distinct epidemiology peaking at 3 years old. Exposure to ionising radiation is an established hazard but it is difficult to gauge the precise risk of less than 100 mSv. Since 1983 significant leukaemia incidences have been reported among families residing near nuclear installations. The target cells (naïve neonatal lymphocytes) get exposed to multiple xenobiotic challenges and undergo extraordinary proliferation and physiological somatic genetic change. Population movements and ionising radiation are considered taking account of updated understanding of radiation biology, cancer cytogenetics and immunological diversity. Double Strand Breaks in DNA arise through metabolic generation of Reactive Oxygen Species, and nearly always are repaired; but mis-repairs can be oncogenic. Recombinant Activating Gene enzymes in rapidly dividing perinatal pre-B lymphocytes being primed for antibody diversity are targeted to Signal Sequences in the Immunoglobulin genes. off target pseudo-sequences may allow RAG enzymes to create autosomal DSBs which, when mis-repaired, become translocated oncogenes. Immunogens acting by chance at crucial stages may facilitate this. In such circumstances, oncogenic DSBs from ionising radiation are less likely to be significant.  相似文献

Purpose.?This article describes the content of and adherence with a nurse-led home visiting programme (Dutch Geriatric Intervention Programme; DGIP) for vulnerable older people. The randomised Dutch EASYcare Study showed positive patient endpoints for DGIP. Describing content and adherence is rarely performed, but highly important for understanding the results of trials.

Method.?DGIP is a complex multicomponent intervention tailored to the patients' needs. This process evaluation describes these components and patient characteristics and creates meaningful clusters of these specific components using hierarchical cluster analysis. Both patient/caregiver and physician adherence rates and possible predictors were investigated.

Results.?In line with the heterogeneity among the subjects, the individual treatment plans turned out to be highly tailored. Cluster analysis identified five clusters of intervention components. DGIP turned out to be largely unsuitable for one group of very vulnerable older participants in urgent need of more care. Overall, physician adherence was 75% and was better than patient adherence (51% complete/partial adherence). Adherence levels increased when both patients, caregivers and physicians received recommendations.

Conclusions.?The content of a multicomponent tailored home-visiting programme was very diverse, matching the heterogeneity among frail elderly subjects. Detailed process and cluster analysis helped to understand the content of the intervention, sharpen target criteria and identify possibilities to improve adherence.  相似文献

In 2005, the elderly generation comprised 20% of the Japanese population. This percentage will grow to approximately 30% in 2030, meaning that nearly one in three people in Japan will be 65 years of age or older. Japan is the first nation in the world to face this situation. This article uses the context of Japanese society to give an overview of the elderly and people with disabilities; the International Classification of Functioning, Disability, and Health model; rehabilitation engineering-related policy; and education. In addition, we examine how governmental programs and Japanese law regarding technical aids may evolve by 2030. Partner robots, intelligent powered wheelchairs, nursing robots, and other technologies are introduced as examples of rehabilitation engineering and assistive technology. We also discuss the volunteer activities of the Rehabilitation Engineering Society of Japan (RESJA) in response to the Asian tsunami disaster and the achievements of a group of students from a Japanese senior high school of industry.  相似文献

Piperazine‐based ‘party pills’ containing 1‐benzylpiperazine (BZP) and 1‐(m‐trifluorophenylmethylphenyl)piperazine (TFMPP) have become increasingly popular in New Zealand and many other countries. The aim of this study was to collect data on the population prevalence and related harm from legal party pill use in New Zealand. A national household sample of 2010 people aged 13–45 years old was collected using a computer‐assisted telephone interviewing (CATI) facility. Twenty per cent of the sample had tried legal party pills and 15% had used them in the previous year. Approximately 40% of males aged 18–24 years old had used legal party pills in the past year. While most users reported fairly minor problems from use, such as insomnia (50% of last year users), some users reported potentially more serious physical problems, such as ‘vomiting’ (12%), ‘inability to urinate’ (10%), ‘chest pains’ (4%) and ‘seizures’ (0.8%). Users also reported a range of psychological problems from use such as visual hallucinations (9%), paranoia (8%) and depression (8%). Two per cent of last year users were classified as dependent on legal party pills using a short dependency scale. The extent of harms and incidences of more serious problems, suggest that stricter regulation of the sale and use of legal party pills in New Zealand may be appropriate.  相似文献

Osteoarthritis is a disease that progresses over time and culminates in the destruction of articular cartilage and joints. Thus, with an increasing elderly population the treatment of knee osteoarthritis has become a major healthcare issue. It has been shown that women are more severely impacted by knee osteoarthritis. Differences in knee anatomy, kinematics, previous knee injury, and hormonal influences may play a role. Sex difference with respect to osteoarthritis presentation, treatment, and the allocation of resources also exists. In general, women present for treatment in more advanced stages of osteoarthritis and have more debilitating pain than their male counterparts. In addition, healthcare providers are more likely to recommend total joint arthroplasty for their male patients. Understanding how and why these gender differences occur is instrumental in formulating an inclusive strategy for combating osteoarthritis in the future.  相似文献
