广东省梅县重点人群碘营养状况调查分析

Objective To estimate the present salt iodine content and iodine nutrition need of high risk population of iodine deficiency disorder in Meixian County. Methods Each primary school was selected from urban and rural areas(Xiyang Town, 20 kilometers away from Meixian County), the goiter rate of 8 to 10 year-old students was examined and urinary iodine and household salt iodine was sampled. Twenty to 40 year-old women of childbearing age nearby schools around the urban and villages around Xiyang Town were selected to collect their urine and salt samples. At urban hospitals and rural health centers, 0 to 2 year-old infant urine samples were collected, Thyroid gland was palpated and urinary iodine was determined by iodine in urine by As3+-Ce4+catalytic spectrophotometry, salt iodine was determined by direct titration. Results The goiter rates of 8 to 10 year-old students were 1.5 % (3/200), 1.0% (1/100) for the urban area and 2.0% (2/100) for rural area. Median of urinary iodine in 8 to 10 year-old students, infants, women of childbearing age averaged at 237.1 μg/L and 280.1, 234.7,187.6 μg/L respectively, with each being 287.4,245.0,205.5 μg/L in urban area and 278.9,228.5,176.4 μg/L in rural area. Women of childbearing age had a higher percentage of urinary iodine < 50.0 μg/L than students,students had a higher percentage than infants, each being 7.5%(15/200), 4.5%(9/200), 4.0%(4/100). The ration of urinary iodine > 300.0 μg/L was more in infants than in students, that in students was more than that in women of childbearing age, each being 33.0% (33/100), 30.0% (60/200),22.5% (45/200). The median of salt iodine was 27.2 mg/kg. The coverage of iodized salt was 100.0%(400/400). Ninty-seven percent(194/200) and 96.0% (192/200) of qualified iodized salt were consumed in urban area and in rural area. Conclusions The amount of iodine added to salt meets the requirement in the 3 kinds population risk of iodine deficiency disorder. But a higher iodine status has been found out in students and infants. It is reasonable to decrease the present salt iodine content.     

Electrocardiogram Interpretation Training and Competency Assessment in Emergency Medicine Residency Programs

OBJECTIVES: To determine the type of electrocardiogram (ECG) interpretation instruction in emergency medicine (EM) residency programs, the use and perceived value of teaching modalities and resources, and the methods used to assess competency of ECG interpretation. METHODS: An interactive survey instrument was posted on the Internet using SurveySuite, Inc., software and e-mailed to program directors (PDs) of all 125 Accreditation Council for Graduate Medical Education-approved U.S. EM residency programs. Responses are reported in total numbers and percentages. RESULTS: Ninety-nine of 125 PDs completed the online survey (response rate, 79.2%). Emergency department instruction (99%), case-based lectures (98%), and didactic lectures (98%) were most commonly used to teach interpretation of ECGs, followed by computer-based instruction (34%) and ECG laboratory (12%). The majority of programs (53%) spent more than eight hours on formal ECG lectures per year, while 11% spent less than three hours. Observation during clinical time (99%), lecture time (76%), and hypothetical cases (57%) were the most common ways to determine competency in reading ECGs, while clinical observation and hypothetical cases were perceived as the most valuable. The most commonly used resource was personal or departmental ECG files (91%), and this had the highest perceived value. The majority of PDs were comfortable with residents' abilities to read ECGs by the third year (96%) and fourth year (91%) of residency. CONCLUSIONS: These data suggest that EM PDs believe that EM residency is adequately preparing graduates to interpret ECGs. This goal is achieved through a variety of methods.     

Learning to Observe Relationships and Coping

Milieu relationships provide the critical background presence to staff's attempts to motivate, regulate, and teach patients how to cope with stress. Forging a connection with hospitalized children and adolescents demands attention to how they respond to adults and engage with staff around milieu expectations. Assessment guides that deal with these issues are presented. Important aspects of children's relatedness are presented in the context of their working models of adults and the influence of these representations on their response to staff. Coping skills are explained with particular emphasis on behavioral coping strategies. Tied to the assessment process are interventions that emphasize staff's role in helping patients manage strong affects and avoid the use of nonproductive behavior regulation strategies.     

Flavocoxid is as effective as naproxen for managing the signs and symptoms of osteoarthritis of the knee in humans: a short-term randomized,double-blind pilot study

Flavocoxid (Limbrel), a proprietary mixture of flavonoid molecules (baicalin and catechin), was tested against a traditional nonsteroidal anti-inflammatory drug, naproxen, for the management of the signs and symptoms of moderate osteoarthritis (OA) in humans. Discomfort and global disease activity were used as the primary end points, and safety assessments were also taken for both treatments as a secondary endpoint. In this double-blind study, 103 subjects were randomly assigned to receive either flavocoxid [500 mg twice daily (BID)] or naproxen (500 mg BID) in a 1-month onset of action trial. Outcome measures included the short Western Ontario and McMaster University Osteoarthritis Index, subject Visual Analogue Scale for discomfort and global response, and investigator Visual Analogue Scale for global response and fecal occult blood. Both flavocoxid and naproxen showed significant reduction in the signs and symptoms of knee OA (P ≤ .001). There were no statistically detectable differences between the flavocoxid and naproxen groups with respect to any of the outcome variables. Similarly, there were no statistically detectable differences between the groups with respect to any adverse event, although there was a trend toward a higher incidence of edema and nonspecific musculoskeletal discomfort in the naproxen group. In this short-term pilot study, flavocoxid was as effective as naproxen in controlling the signs and symptoms of OA of the knee and would present a safe and effective option for those individuals on traditional nonsteroidal anti-inflammatory drugs or cyclooxygenase-2 inhibitors. A low incidence of adverse events was reported for both groups.

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.     

Clinical and Actuarial Prediction of Physical Violence in a Forensic Intellectual Disability Hospital: A Longitudinal Study

Background There is a high rate of physical violence in populations with intellectual disabilities, and this has been linked to problems for the victim, the assailant, members of staff and services. Despite the clinical significance of this behaviour, few studies have assessed methods of predicting its occurrence. The present study examined clinical and actuarial methods of predicting violence in a forensic intellectual disability hospital. Methods The sample for the study consisted of people resident in the hospital during a 1‐year period (n = 124). Clinical prediction used a risk rating made by members of the person's clinical team, whereas actuarial prediction used the number of violent incidents in the 6‐months before the date of the clinical risk assessment. Computerized hospital records of violence in the 6 months after the assessment were used to examine the predictive accuracy of the two methods. Results The clinical method produced an area under the curve of 0.74 (95% CI: 0.65–0.83) in a receiver–operating characteristic curve analysis. The value for the actuarial method was 0.77 (95% CI: 0.69–0.86). Both methods performed at levels significantly above chance, but no one method was found to be superior to the other. Conclusions These findings suggest that it is possible to predict who is at risk of violence in forensic populations with intellectual disabilities. Here, the authors discuss the clinical implications of these findings and the clinical application of risk prediction within clinical services.     

智力残疾的适应性行为评估

适应性行为评估是智力残疾诊断与干预的必要依据。适应性行为的概念至今仍未有统一的观点，AAMR（2002）认为，适应性行为指的是概念、社会和应用3方面的技能，它的限制会影响个体的日常生活运作，进而影响其生活适应。对适应性行为进行评估的方法主要有测验法、行为观察法、功能性评估、生活质量评估和社会技能测量。无论使用什么方法进行评估，都应当以改善智力残疾个体现有状况为目的，考虑到各种评估方法的局限性，对智力残疾个体宜进行全面评估。     

Respondent and informant accounts of psychiatric symptoms in a sample of patients with learning disability

This paper investigates differences in the nature and frequency of psychiatric symptoms reported by patients with learning disability and by key informants. The study involved psychiatric assessment of 100 patients with learning disabilities and key informants using the Psychiatric Assessment Schedule for Adults with a Developmental Disability (PAS-ADD), a semi-structured psychiatric interview developed specifically for people who have a learning disability. There was considerable disagreement between respondent and informant interviews; only 40.7% of cases were detected by both interviews. Respondents were more likely to report on autonomic symptoms and certain psychotic phenomena. Other anxiety and depression symptoms were more frequently reported by infcrnnants. The results indicate that it is crucial for sensitive case detection to complete both interviews where possible. If the respondent cannot be interviewed, panic disorder or phobias may be particularly difficult to detect.
