睡眠信念与态度量表在失眠患者健康教育中的应用

目的: 采用睡眠个人信念与态度量表探索患者睡眠障碍与哪些歪曲的信念有关,针对歪曲的信念进行睡眠实践教育,达到促进睡眠的目的.方法: 连续收集62例以失眠为主诉的患者,随机分成试验组与对照组,各31例,两组均在药物治疗及心理治疗基础上进行睡眠健康教育.试验组针对患者自身存在的歪曲信念态度进行健康教育,而对照组只进行常规的健康宣教.入组前及入组后每周,应用睡眠个人信念与态度量表(Dysfunctional Beliefs and Attitudes about Sleep Scale,DBAS)、匹茨堡睡眠指数量表(Pittsburgh Sleep Quality Index,PSQI)对两组进行测评,同时让患者评价睡眠时间、睡眠质量、睡眠效果和对健康教育接受程度.结果: 健康教育4周后试验组和对照组DBAS得分均高于人组时[(111.0±8.7)vs.(88.9±12.3)、(93.5±17.2)vs.(81.3±19.2),P:0.001、0.010],而PSQI得分均低于入组时[(5.5±2.1)vs.(10.9±4.4)、(9.0 ±2.1)vs.(11.5±3.6),均P=0.001];健康教育4周后对照组的DBAS得分低于实验组,而PSQI得分高于实验组.健康教育后试验组对睡眠时间、睡眠质量、睡眠效果满意的比例均明显提高,睡眠时间满意的比例由18/31到30/31,对睡眠质量满意比例由8/31变为23/31,对睡眠效果满意比例由8/31到21/31(均P＜0.05).试验组对睡眠时间满意的比例明显高于对照组(30/31 vs.14/31,P＜0.01),对健康教育的接受程度也明显高于对照组(18/31 vs.5/31,P＜0.05).结论: 试验组健康教育后患者的睡眠信念有了明显的改善,睡眠质量有了提高.     

Adult T cell leukemia/lymphoma with massive involvement of cardiac muscle and valves

An autopsy case of a 58-year-old woman with massive cardiac Involvement of adult T cell leukemia/lymphoma (ATLL) is reported. She developed cardiac failure due to aortic and mitral regurgitation with cardiac infiltration of ATLL cells, and underwent replacement of both aortic and mitral valves. Studies of the cut-surfaces revealed diffuse thickening of the subendocardial wall of the left chamber with widespread whitish-brown tumor infiltrates. In the regions surrounding the replaced aortic and mitral valves there was also massive tumor cell infiltration. The tumor cells infiltrating the cardiac muscle wall were T cell in origin and exhibited Leu-3a (CD4)-positive immunoreaction. Ultrastructurally, tumor cells contained markedly indented nuclei and some were attached directly to the muscle cells. These findings suggest that this was an unusual form of ATLL with widespread involvement of the heart.     

Plasticity of the central nervous system—a neurosurgeon's experience of cerebral compensation and decompensation

Summary Cerebral plasticity constitutes one of the most decisive factors in recovery and readaptation after cerebral lesions. In contrast to the considerable progress in current studies on normal neuronal plasticity including the idea of l'homme neuronal, the concept of plasticity postulated by Albrecht Bethe in 1929 received little attention. The author, as a neurosurgeon, has tried to describe cranial morphological plasticity, morphological and functional plasticity in infantile encephalopathies and especially in hemiatrophic lesions. It is supposed that a true morphological substrate exists due to compensatory hyperplasia of the uninvolved hemisphere.Modern neurosurgical techniques have demonstrated that the functional plastic capacity is much larger than has been supposed, even in the elderly. Some aspects of the mechanisms of compensation and decompensation of cortical and subcortical structures as well as of the central regulation systems are discussed. The full extent of the amazing recovery and functional reorganization is reached by plastic capacity, personal motivation, adequate training and sufficient time.The contribution ends with an exposition of a personal philosophy concerning psycho-somatic dualism, the body-mind problem, the future of the human brain and the ethical outlook, based on the progressive biological evolution of the basal neocortex and the immanent functional development (H. Spatz).In grateful memory of my paternal friends, the great German brain researchers Julius Hallervorden (1882–1965) and Hugo Spatz (1888–1969).     

Beta-2-adrenoceptor agonists as inhibitors of lung vascular permeability to radiolabelled transferrin in the adult respiratory distress syndrome in man

Increased lung vascular permeability leading to increased plasma protein extravasation and accumulation (PPA) is a characteristic feature of acute lung injury. Using a previously described technique, PPA was monitored in the lungs of patients with the adult respiratory distress syndrome (ARDS) — an extreme example of acute lung injury in man. An external radiation probe detector was used to monitor the pulmonary accumulation of the plasma protein transferrin radiolabelled in-vivo with ^113mIn. Ten patients with ARDS exhibiting increased PPA indices (>1.0x10^-3/min) were given an intravenous infusion of terbutaline (7 g/kg) over 30 min. Of the four patients in whom the post-drug PPA indices remained within the ARDS range, none survived, whilst five of the six patients in whom the post-drug PPA indices were reduced to below 1.0x10^-3/min survived. PPA indices prior to the administration of terbutaline were not significantly different between the survivor (n=5) and non-survivor (n=5) groups. There was a significant decrease in the PPA indices following terbutaline in survivors (p<0.01) but not in non-survivors. Thus beta-2-agonists in therapeutic doses can inhibit increased lung vascular permeability in man. These findings may have prognostic and therapeutic implication for beta-2-agonists in ARDS.     

Prevalence of mental disorder in an urban population in central Sweden

The principal reason for this epidemiological study was the lack of psychiatric morbidity studies in a predominantly urban population, by psychiatrists in direct interviews. The psychiatric examination, covering 1970-71, included a representative selection of 2,283 persons, 18-65 years old from "former" Stockholm County, and the 12-month prevalence of mental disorders was measured. The total of non-participants was 12%. Forty-seven percent had a psychiatric diagnosis - significantly more women (54%) than men (40%). Excluding the psychosomatic diagnoses, 31% of the population received a psychiatric diagnosis, which agrees closely with other contemporary studies of mental disorder in the Nordic countries. The primary diagnoses were: neuroses 26%, psychosomatic diagnoses 16%, schizophrenic/paranoid conditions or other psychoses 0.6%, affective disorders 0.2%, psychoorganic syndromes 1.2%, psychopathy 0.2%, character neurosis 1%, drug dependence 0.2% (as a primary or a secondary diagnosis 0.6%), alcoholism 1.4% (as a primary or a secondary diagnosis 3.1%) and mental retardation 0.4% (as a primary or a secondary diagnosis 0.8%).

Scanning and synthesizing Canadian policies that address the school-to-work transition of youth and young adults with disabilities

BackgroundDisability faced by a young person can impact the school-to-work transition and shape health and well-being over the life course. Unique barriers to entry and advancement within the labor market that are relevant to young people with disabilities underscore the need for tailored policy-level supports.ObjectivesTo examine and describe policies that support the school-to-work transition of young people with disabilities in Canada.MethodsA scan of policies which focused on the school-to-work transition of young people with disabilities across Canada was conducted between June 2019 and January 2020. Searches were completed within federal, provincial and territorial policy portals. Each policy relating to employment participation of people with disabilities was summarized. Policies that focused on the school-to-work-specific were synthesized using Bemelmans-Vidic, Rist and Vedung's policy tool framework.ResultsA total of 36 policies were identified by our scan that focused on the employment of people with disabilities. Only five policies explicitly addressed the school-to-work transition. All existing policies were implemented at the provincial level and aimed to promote entry into employment. The synthesis of policies revealed that financial policy tools were primarily used to incentivize employment, provision of workplace accommodations, or the development and implementation of job readiness programs.ConclusionOur analysis of federal, provincial and territorial policies in Canada uncovered a limited number of policies that specifically support the school-to-work transition. Addressing these policy gaps can increase the inclusion of young people with disabilities in the labor market.     

Implementing a Transition Program from Paediatric to Adult Services in Phenylketonuria: Results after Two Years of Follow-Up with an Adult Team

We aimed to report the implementation of a phenylketonuria (PKU) transition program and study the effects of follow-up with an adult team on metabolic control, adherence, and loss of follow-up. Fifty-five PKU patients were analysed in the study periods (SP): 2 years before (SP1) and after the beginning of adult care (SP2). Retrospective data on metabolic control and number of clinic appointments were collected for each SP, and protein intakes were analysed. In SP2, three patients (6%) were lost to follow-up. There was a small but statistically significant increase in median number of annual blood spots from SP1 to SP2: 11 (7–15) vs. 14 (7–20); p = 0.002. Mean ± SD of median blood Phe remained stable (525 ± 248 µmol/L vs. 552 ± 225 µmol/L; p = 0.100); median % of blood Phe < 480 µmol/L decreased (51 (4–96)% vs. 37 (5–85)%; p = 0.041) and median number of clinic appointments increased from SP1 to SP2: (5 (4–6) vs. 11 (8–13); p < 0.001). No significant differences were found regarding any parameter of protein intake. Our results suggest that the implementation of an adult service was successful as impact on metabolic control was limited and attendance remained high. Continuous dietetic care likely contributed to these results by keeping patients in follow-up and committed to treatment.     

Perceptions,professional responsibility and management experiences of patients with alcohol,tobacco and opioid use disorder by residents in general practice and teaching general practitioners

BackgroundSubstance use disorders (SUDs) are based on pathophysiological mechanisms common to all psychoactive substances. However, general practitioners (GPs) hold different views depending on the substance in question.ObjectivesTo determine whether the perceptions that teaching GPs and final-year residents in general practice have of patients with a SUD vary according to the substance involved and explore their professional responsibility and management experiences.MethodsA cross-sectional observational study was carried out by asking residents and teaching GPs from eight faculties of medicine about their perceptions, professional responsibility and management experience of patients with tobacco, alcohol and opioid use disorders, using an online questionnaire between June and September 2017.ResultsThe responses of 238 teaching GPs (mean age 50 years SD 3.5; 58% men) and 327 residents (mean age 28 years SD 9.9; 67% women) were analysed (response rates: 9 and 15% respectively). Tobacco smokers were considered to be more responsible for their acts than the other users. Teaching GPs and residents considered that it was their responsibility to discuss substance use. They did not feel able to manage alcohol and opioid use disorders. Tobacco cessation was mainly managed alone (78%). The results were quite similar among teaching GPs and residents.ConclusionThe majority of practitioners had no difficulty managing smoking cessation. During the management of alcohol and particularly opioid use disorders, practitioners did not feel competent. The gap between their perceived responsibility and competencies should be addressed by training and promoting collaborative care.     

Diagnostic Testing in Long-Term Care and Resident Emergency Department Visits: A Retrospective Cohort Study

ObjectivesTo investigate the association between rapid access to radiographs, blood tests, urine cultures, and intravenous (IV) therapy in a long-term care (LTC) home with resident transfers to the emergency department (ED).DesignRetrospective cohort study.Setting and Participants21,811 residents living in 162 LTC homes in Ontario, Canada.MethodsWe administered a survey to LTC homes to collect wait times for radiographs, basic blood tests, urine culture, and IV therapy. Rapid availability was defined as typically receiving test results within 1 or 2 days, or same-day IV therapy. We linked the survey results to administrative data and defined a cohort of residents living in survey-respondent homes between January and May 2017. We followed residents in the linked administrative databases for 6 months, until discharge, or death. Two physicians identified diagnostic codes for ED visits that were potentially preventable with rapid availability of each of the 4 resources. Multilevel logistic regression models estimated associations between potentially preventable ED visits and rapid diagnostic tests and intravenous access while controlling for demographic characteristics, illness severity, LTC home size, chain status, and physician availability.ResultsRapid blood tests, radiographs, urine culture, and IV therapy were available in 55%, 47%, 34%, and 45% of LTC homes, respectively. LTC homes that were part of multihome chains were less likely to have rapid access to the 4 resources. Of the 4736 residents (27%) who visited an ED during follow-up, individuals from homes with rapid access to radiographs (odds ratio 0.79, 95% confidence interval 0.66-0.97), urine culture (0.88, 0.72-1.08), blood tests (0.83, 0.69-1.00), and IV therapy (0.93, 0.70-1.23) tended to have fewer potentially preventable ED visits.Conclusions and ImplicationsRapid access to diagnostic testing and IV therapy in LTC reduced ED visits. Improving access to these resources may prevent ED visits and allow residents to stay home.
