Soul City: a sustainable edutainment vehicle facilitating social change

This paper outlines the programming model employed by the Soul City Institute for Health and Development Communication, a South African NGO, in using ‘edutainment’ to facilitate social change. The paper refers to the intersection of this model and current thought on health promotion and various social change theories. It also discusses key challenges and factors contributing to sustainability over 12 years.     

Robotic-assisted heller myotomy versus laparoscopic heller myotomy for the treatment of esophageal achalasia: multicenter study

Laparoscopic Heller myotomy (LHM) has become the standard treatment option for achalasia. The incidence of esophageal perforation reported is about 5%–10%. Robotically assisted Heller myotomy (RAHM) is emerging as a safe alternative to LHM. Data comparing the two approaches are scant. The aim of this study was to compare RAHM with LHM in terms of efficacy and safety for treatment of achalasia. A total of 121 patients underwent surgical treatment of achalasia at three institutions. A retrospective review of prospectively collected perioperative data was performed. Patients were divided into two groups: group A (RAHM), 59 patients, and group B (LHM), 62 patients. All the operations were completed using minimally invasive techniques. There were 63 women and 58 men, with a mean age of 45 ±19 years (14–82 years). Fifty-one percent of patients in group A and 95% of patients in group B reported weight loss. Duration of symptoms was equal for both groups. Dysphagia was the main complaint in both groups (P = NS). There was no difference in preoperative endoscopic treatment in both groups (44% versus 27%, P = NS). Operative time was significantly shorter for LHM in the first half of the experience (141 ± 49 versus 122 ± 44 minutes, P < .05). However, in the last 30 cases there was no difference in operative time between the groups (P = NS). Intraoperative complications (esophageal perforation) were more frequent in group B (16% versus 0%). The incidence of postoperative heartburn did not differ by group. There were no deaths. At 18 and 22 months, 92% and 90% of patients had relief of their dysphagia. This study suggests that RAHM is safer than LHM, because it decreases the incidence of esophageal perforation to 0%, even in patients who had previous treatment. At short-term follow-up, relief of dysphagia was equally achieved in both groups.

Health promotion training needs analysis: an integral role for clinical nurses in Lanarkshire,Scotland*

Training needs analysis is considered essential to professional and organizational development, for continuing education and for incorporation into professional practice. Increasingly, nurses are encouraged to develop their health promotion role. Despite this there has been relatively little research in Scotland into the health promotion role of the hospital nurse. This study describes the results of a health promotion training needs analysis undertaken on qualified, hospital-based nurses in Lanarkshire, Scotland. Information on the nurses' current health promotion practices, their attitudes and beliefs, their views on role development and priorities for further training were collated, analysed and discussed within the framework of the Health Action Model. This model was originally designed to assist understanding of the gap that exists between an individual intention to act and the eventual health action. However, in this study the ways in which ‘cognitive factors’ (knowledge and beliefs) and ‘motivational factors’ (considering values, attitudes and drives) and pressures from social norms and significant others assisted in the understanding of the nurse's orientation to, and beliefs about, health promotion practice. Fifty-seven per cent of nurses in the study considered health promotion activities to be emerging in clinical care and 4% considered them to be advanced. The interest respondents have in role development and the further integration of health promotion activities into nursing practice was explored by ascertaining the nurses' attitudes and beliefs about their own health promotion role. Of 107 respondents, a majority 72 (67%) agreed health promotion interventions to be an important function of the nurse with 29 (27%) strongly agreeing (n=107). Sixty per cent stated they would be interested in developing their role and 30% were very strongly interested. Recommendations are therefore made for future planning and development strategies for the health promotion role of hospital nurses.     

维持性血透患者的心理状态研究

研究我国血透患者的心理状况并进行针对性的心理治疗。方法 采用症状自评量表(SCL90-R)、多维度健康状况心理控制源量表(MHLC)、艾森克个性问卷(EPQ)及终末期肾脏病(ESRD)患者专用的生活质量表对北京六个医院透析中心的92名维持性血透患者进行了心理状态的研究,并与美国及加拿大相同的研究进行了比较分析。结果 本组的血透存在着抑郁、焦虑、恐怖等心理障碍,出现心理障碍的比例显著高于美国同类患者(P<0.01),且焦虑的发生率高于美国同类患者(P<0.01)。这些障碍与MHLC中机遇项分(CED)显著相关(P<0.01)。EPQ中神经质项分高者倾向于发生抑郁、焦虑等心理障碍。本组的血透患者客观生活质量较加拿大同类患者低(P<0.01),但在总的生活满意度上没有显著性差异。生活质量与心理及躯体因素均呈显著相关,心理障碍与躯体症状也显著相关(P<0.01)。结论 本组的血透患者心理状态与美国加拿大同类患者相比既有相同之处,又有特殊之处。我们应该兼顾病人的躯体和精神两方面的健康,努力提高他们的生活质量。     

Articulation of Asthma and Its Care Among Low-Income Emergency Care Recipients

Low-income minority patients from East St. Louis, Illinois, a depressed midwestern urban city, who had visited acute care settings with asthma symptoms, participated in a focus group. Questions were constructed around the Health Belief Model to characterize participants' experiences in receiving asthma care, their confidence in long-term asthma self-management, barriers they perceived to managing their asthma, and recommendations they would make for improving asthma care in their community. Analysis of comments suggests an appreciable understanding of asthma triggers, limited coping behaviors for asthma symptoms, very limited practice of active asthma management, perception of the health care system as frequently insensitive to their needs or their knowledge of their own care, exchange of well-articulated information regarding how to deal with the system, and an apparent lack of awareness of any potential contribution of patient education or support system.     

Mature-age entrants to medical school: a controlled study of sociodemographic characteristics, career choice and job satisfaction

A comparison of 121 mature-age and 270 normal-age entrants who graduated from the University of Queensland Medical School between 1972 and 1987 shows that mature-age entrants are some 7 years older, are more likely to come from public (state) schools and less likely to have parents in professional/technical occupations. Otherwise, the two groups were similar in terms of gender, marital status, number of children, ethnic background and current practice location. The educational background of mature-age entrants prior to admission includes 44.6% with degrees in health-science areas and 31.4% with degrees in non-health areas. Reasons for delayed entry of mature-age entrants include late consideration of medicine as a career (34.7%), financial problems (31.4%), dissatisfaction with previous career (30.6%), poor academic results (19.8%), or a combination of the above factors. Motivations to study medicine include family influences (more so in normal-age entrants), altruistic reasons (more so in mature-age entrants) and a variety of personal/social factors such as intellectual satisfaction, prestige and financial security (similar for both groups) and parental expectations (more so in normal-age entrants). Mature-age entrants experienced greater stress throughout the medical course, especially with regard to financial difficulties, loneliness/isolation from the students and family problems (a greater proportion were married with children). While whole-course grades were similar in both groups, normal-age entrants tended to win more undergraduate honours/prizes and postgraduate diplomas/degrees, including specialist qualifications. Practice settings were similar in terms of group private practice, hospital/clinic practice or medical administration, but there was a greater proportion of mature-age entrants in solo private practice, and a smaller proportion in teaching/research. If given the time over, some two-thirds of both groups would choose medicine as a career. Reasons for job satisfaction include helping patients, intellectual stimulation and financial rewards. Reasons for dissatisfaction include pressure of work, red-tape/paperwork, 'doctor-bashing', long working hours, emotional strain, financial pressure, unfulfilled career expectations and irritation with trivial medical complaints.     

Deficiencies of Vitamins in CAPD Patients: The Effect of Supplementation

Concentrations of the vitamins B₁, B₂, B₆, B₁₂, C, folic acid,A, E and ß-carotene were determined in blood and 24-hdialysate in 44 CAPD patients. Twenty-five of these patientswere studied during chronic treatment (mean 313 days, range60–1034 days). Nineteen patients were studied during training.In a longitudinal study, 11 patients were analysed again after77–507 (mean 238) days. In both patient groups a considerable portion of patients (11%–64%)had blood concentrations indicative of a deficiency of the vitaminsB₁, B₆, C and folic acid. The average concentrations of thesevitamins were normal in both groups. The only abnormal findingwas the mean EGOT activity being deficient in patients on chronictreatment. Mean concentrations of vitamin A were above normalin both groups. In the longitudinal study a significant increaseof vitamin B₂ and a decrease of vitamin B₆ in blood was found. When compared to 24-h excretion in normal urine, loss with 24-hdialysate was low for vitamin B₁, normal to relatively highfor vitamin B₂ and B₆, but extremely high for vitamin C andfolic acid. The vitamins B₁₂, A, E and carotenoids were hardlydetectable in the dialysate. In ten other patients the effect of daily supplementation with2 mg vitamin B₆, 100mg vitamin C and 400 µg folic acidwas analysed during a 16-week period. In all patients a significantincrease in blood concentrations was obtained. It is concludedthat these dosages were sufficient to maintain a normal statusof these vitamins in CAPD patients.     

Negative symptoms in schizophrenia: considerations for clinical trials

There is little agreement about the methodology of clinical trials of antipsychotic drugs in patients with negative symptoms. A literature review revealed wide variation in experimental design, rating scales and study duration. This reflects differing views as to the definition and response to treatment of negative symptoms. Some degree of standardization would improve comparability of studies and aid the development of new compounds. Patients included in such studies should have displayed negative symptoms for at least 6 months. Depressive symptoms, positive schizophrenic symptoms and extrapyramidal signs may all influence or be confused with negative symptoms and may respond to treatment; they should be at a low level at baseline and should be measured during the study period. Studies should last at least 8 weeks. Several scales are available for measuring negative symptoms and are reviewed; a global impression score should be used additionally.
