Strengthening research capability, funding and sustainability: a personal perspective.

The need to strengthen research capability has led organizations to provide research-oriented training programs, including various short courses and protocol development workshops, at the end of which it is anticipated that the participants will be able to carry out the research work. However, to do research needs more than just training; it also requires funds, a research infrastructure, technical back-up and other support. This paper compares two of these programs from the perspective of an attendant: WHO/TDR's Fieldlincs program and the CAPS (Center for AIDS Prevention Studies) International Program. The paper also describes the experience of the approaches that have been used to get research funding. In addition, issues related to sustaining researchers in the field are discussed.

Factors affecting the work efforts of disabled-worker beneficiaries.

Congress is currently placing considerable emphasis on returning disabled-worker beneficiaries to work. However, going back to work is only the first step in the complex process of program termination due to work and trust fund savings. Not only must the beneficiary get a job, but also the work effort must be sustained at what is considered a substantial gainful activity (SGA) level by the disability program (so that an SGA termination will result) and a reasonable living condition must be achieved by the beneficiary (so that the person is motivated to continue working and lose benefits). This article focuses on those factors that affect the ability of the beneficiary to sustain such a work effort. Combined with previous findings about returning to work, we begin to see the overall effect of the factors on work efforts. Beneficiaries who have physical therapy rehabilitation have a higher tendency to start working and a lower tendency to stop. Those with vocational training or general education have a higher tendency to start working, but these factors do not help to sustain the effort. Beneficiaries who were helped with job placement have a higher tendency to start work, but they also have a higher tendency to stop. If beneficiaries knew about the trial-work period, but not about either the extended period of eligibility or Medicare continuation, then they had a higher tendency to start work and a higher tendency to stop. However, if they knew about all three work-incentive provisions, then the tendency to work was not affected.

[Sudden death and chronic cardiac insufficiency].

Sudden death accounts for about 35% of the mortality of cardiac failure and its incidence does not decrease with the use of angiotensin converting enzyme inhibitors. Non-sustained ventricular tachycardia on Holter monitoring, late ventricular potentials and tachycardia induced by programmed ventricular stimulation have no formal predictive value of sudden death, underlining the varied character of the mechanisms underlying sudden death during cardiac failure. Sustained ventricular tachycardia degenerating to ventricular fibrillation is only one of the rhythmic factors implicated together with inaugural ventricular fibrillation, bradyarrhythmias and electromechanical dissociation. The underlying cardiac disease plays a role in the initiation of the fatal arrhythmia. In coronary artery disease, recurrent acute ischaemia is the principal trigger factor in patients who often have triple vessel disease. This explains the fact that classic markers of arrhythmia in the post-infarction period, which are only the reflection of the arrhythmogenic substrate of ventricular tachycardia, usually due to reentry around the fibrous scar of the infarct, are not valid in patients with progressive ischaemic cardiomyopathy. The most effective antiarrhythmic treatment in this type of patient is the prevention of ischaemia, when possible. In primary dilated cardiomyopathy, the mechanism underlying sudden death could be different at each stage. In NYHA Stages I and II, ventricular tachyarrhythmias could play a major part in unexpected sudden death in patients whose stable haemodynamic status suggested a more prolonged survival. The value of an implantable defibrillator would seem to be proved in this group of patients, at least in secondary prevention. In Stages III and IV, ventricular arrhythmias only indicate the degree of ventricular dysfunction and sudden death may follow bradyarrhythmias and electromechanical dissociation due to the precarious haemodynamic status.

Initial clinical experience with a fully automatic in-hospital external cardioverter defibrillator.

Sudden cardiac death due to ventricular tachyarrhythmia remains a significant problem in the in-hospital setting. Although the probability of survival is closely correlated with the rapidity of a response by qualified personnel, response times can be prolonged, even in specialized care units. In an effort to decrease response time, a fully automatic external cardioverter defibrillator was recently devised. This device was evaluated in the in-hospital setting to assess safety and efficacy. A total of 79 patients were studied in a multicenter trial. Patients were monitored with fully functional devices in the electrophysiology laboratory (51 patients) and in the cardiac care unit (28 patients). Performance of the device was assessed by comparing automatic responses to any sustained change in cardiac rhythm, either spontaneous or induced, to a retrospective review of stored ECG data and programmed parameters. During a total duration of 964 hours of monitoring, there were 99 episodes of sustained tachycardia. Therapy was appropriately delivered or advised in all episodes. Therapy was advised in one episode of supraventricular tachycardia. There were no episodes of inappropriate therapy delivery. There were no complications or adverse events. The device performed with a sensitivity of 100% and specificity of 98.8% with an average response time of 22 seconds. In conclusion, this automatic external defibrillator was safe, effective, and functioned as designed. Significant improvement in response time to life-threatening ventricular tachyarrhythmia in the in-hospital setting would be expected if this technology was widely adopted.

Time-domain and spectral turbulence analyses of the signal-averaged electrocardiogram have different predictive values for sustained ventricular tachycardia in patients with myocardial infarction.

We performed signal-averaged ECG and programmed stimulation in 15 patients after myocardial infarction with ventricular tachycardia and 49 patients after myocardial infarction without ventricular tachycardia to compare the spectral turbulence analysis and time-domain analysis of signal-averaged ECG for prediction of clinical and induced ventricular tachycardia. Sustained monomorphic ventricular tachycardia was inducible in all 15 patients with clinical sustained monomorphic ventricular tachycardia (group 1) and in 9 patients without clinical sustained monomorphic ventricular tachycardia (group 2). Sustained monomorphic ventricular tachycardia was not inducible in 40 patients without clinical sustained monomorphic ventricular tachycardia (group 3). While there was no difference in time-domain variables between groups 1 and 2, there were significant differences between groups 2 and 3. Values obtained by spectral turbulence analysis differed significantly between groups 1 and 2, but not between groups 2 and 3. Time-domain analysis showed abnormal values in 87% of group 1 patients, 78% of group 2, and 35% of group 3. Spectral turbulence analysis showed abnormal values in 93% of group 1, 11% of group 2, and 30% of group 3. In conclusion, frequency-domain spectral turbulence analysis of signal-averaged ECG is more useful than the time-domain analysis in predicting the spontaneous occurrence of sustained monomorphic ventricular tachycardia in patients after myocardial infarction.

Nutrition knowledge and practices, and consumption of vitamin A--rich plants by rural Nepali participants and nonparticipants in a kitchen-garden program.

Food-based nutrition interventions, including kitchen gardens and nutrition education, offer a potentially sustainable approach to reducing multiple nutritional deficiencies, but they have been poorly evaluated in developing countries. In a poor region of the terai (the flat, subtropical agricultural region that borders on India) in rural Nepal, we developed and evaluated the impact of a nutrition program added to the Market Access for Rural Development (MARD) Project. The primary objective of the MARD Project was to augment household income by increasing the production of high-economic-value crops. The objective of the nutrition program was to increase vitamin A and iron intakes by promoting kitchen gardens (training, technical assistance, and seed distribution) and nutrition education. One-third of the kitchen-garden program participants also attended nutrition education or agricultural training sessions that were part of the MARD Project. The program was evaluated after 36 months by a cross-sectional nutrition survey in 430 MARD households with kitchen gardens and 389 non-MARD control households. The lack of knowledge about nutrition, including the causes, prevention, and treatment of night-blindness and anemia, was remarkable. However, compared with control households, the kitchen-gardens group had significantly more nutrition knowledge (38% vs. 13% knew one of the causes of night-blindness, and 17% vs. 3% knew one of the causes of anemia), were more likely to feed special complementary foods to infants and to preserve food, and consumed more of 16 types of home-produced micronutrient-rich vegetables and fruits. Although the cross-sectional nature of the study limits our ability to attribute these differences to the program, we observed a striking lack of nutrition knowledge in these communities, and a clear opportunity to increase the intake of vitamin A through home production of vitamin A-rich plants.

Outcomes of American Lung Association-Indiana Lung Centers asthma program.

The American Lung Association of Indiana (ALA-I), in conjunction with participating Indiana hospitals, developed the Lung Center concept as a mechanism to provide standardized delivery of lung health education. The goal of this pilot study was to evaluate initial experience with the Lung Center program "Overcoming Your Asthma," a two-session asthma education program, and identify areas needing improvement. A total of 305 participants responded to a 31-item questionnaire at baseline (immediately prior to program exposure) and again at 1 month (n = 75) and 6 months (n = 30) after participation. Overall, delivery of the ALA-I Lung Center asthma education program improved respondents' experience with asthma. At one month after the educational session, the program improved participant knowledge about asthma. This was associated with modest improvements in treatment behaviors, economic outcomes and asthma symptoms such as reduced breathing difficulties, wheezing and asthma exacerbations, and improvement in sleep. Improvements were not uniformly sustained at 6 months. In summary, the Lung Center asthma education program appears to benefit patients with asthma. The results provide preliminary evidence to support continued delivery of asthma education in Lung Centers. Future efforts should emphasize education to improve treatment attitudes and behaviors.

Results of electrophysiological testing and long-term follow-up in patients sustaining cardiac arrest only while receiving type IA antiarrhythmic agents.

UNLABELLED: Therapeutic management of patients sustaining a cardiac arrest while receiving antiarrhythmic agents can be difficult since the role of the drug in possibly facilitating the arrhythmia is often difficult to define. To determine if the response to programmed stimulation could give insight into which patients may have experienced a drug-induced cardiac arrest, we studied 29 patients (61 +/- 9 years) with no prior history of sustained ventricular tachyarrhythmias (VT) who suffered a cardiac arrest only while receiving type Ia antiarrhythmic agents. Patients with documented myocardial infarction, acute ischemia, electrolyte abnormalities, or torsade de pointes were excluded from the study. Twenty-four patients had coronary artery disease with prior myocardial infarction (ejection fraction 28% +/- 9%) and five patients had idiopathic dilated cardiomyopathy (ejection fraction 31% +/- 6%). During baseline electrophysiological testing, 19 patients (66%) had inducible sustained ventricular arrhythmias: uniform VT, n = 14 (group I), polymorphic VT or ventricular fibrillation, n = 5 (group II). Ten patients (group III) had no inducible sustained ventricular arrhythmias. To determine if rechallenge with a type Ia agent could facilitate induction of a sustained ventricular arrhythmia in group III, eight patients underwent ten electrophysiological studies during therapy with either procainamide or quinidine. Only two patients developed sustained VT in response to programmed stimulation. Patients in groups I and II received therapy guided by electrophysiological testing, including antiarrhythmic agents alone (n = 8), subendocardial resection (n = 4), or an implantable cardioverter defibrillator (n = 7). Patients in group III received antiarrhythmic agents empirically (n = 3), or for treatment of atrial tachyarrhythmias (n = 2) or nonsustained VT (n = 1). In addition, four patients in group III received an implantable cardioverter defibrillator. During a mean follow-up of 28 +/- 27 months (range: 1 day-84 months) 13 patients died suddenly or received a defibrillator shock preceded by syncope or presyncope: group I: n = 5; group II: n = 2; group III: n = 6. IN CONCLUSION: (1) most patients sustaining a cardiac arrest only in the presence of type Ia antiarrhythmic agents have inducible sustained VT in the absence of antiarrhythmic agents, and (2) the risk of recurrent VT persists in patients without inducible sustained arrhythmias in the drug-free state, regardless of whether they manifest inducible arrhythmias after rechallenge with a type Ia agent.

Induction of sustained ventricular tachycardia after surgical repair of tetralogy of Fallot.

Between 1980 and 1996, 89 unselected consecutive patients with repaired tetralogy of Fallot (TOF) underwent examination, including a prospective right ventricular programmed stimulation with the same protocol (S1 S2, S3, S4). Age at surgery was 4.2 +/- 3.5 years and age at electrophysiologic study was 10.9 +/- 6.5 years. Follow-up since surgery was 14.4 +/- 4.8 years and patient follow-up after programmed stimulation was 7.8 +/- 4.2 years. The aim of this study was to evaluate the main predictors of the inducibility of a sustained monomorphic ventricular tachycardia (VT) and its significance to identify a group of patients at risk of sudden death: 21 (group A) had and 68 (group B) had no induced sustained VT. The induction of VT was related to older age at programmed stimulation, prolonged QRS duration, presence of complex ventricular arrhythmia, symptoms, right ventricular overload, and increased right ventricular systolic pressure. Predictors of induced VT selected by multivariate analysis were age at electrophysiologic study (p <0.0001), previous palliative shunts (p <0.001), right ventricular systolic pressure (p <0.007), and symptoms (p <0.005). Among group A patients, 4 had previous sustained VT before stimulation, and 1 had sustained VT only during follow-up after stimulation. No patients of group B had clinical sustained VT. Late mortality was low but similar between both groups. A negative electrophysiologic study may be helpful for the management of patients after surgical repair of TOF, but because the arrhythmic event rate is low, the findings of even a positive electrophysiologic study should be interpreted with caution.

The role of the registered nurse-first assistant in the implantable left ventricular assist device program.

Successful support of patients using the implantable left ventricular assist device requires sustained and coordinated efforts by physicians and medical personnel. The authors describe the role of their registered nurse-first assistant (RNFA) as it has evolved through caring for 43 implantable pneumatic left ventricular assist device patients and 8 vented-electric left ventricular assist system patients during a 3 year period. Intraoperatively, the RNFA is responsible for pump assembly, including pre sealing all grafts and connecting areas of the pump using a combination of cryoprecipitate and thrombin. The RNFA assists with pump insertion during surgery. At device explantation, the RNFA dismantles the pump according to the FDA protocol for disassembly. Post operatively, the RNFA assesses and maintains patient hemodynamic stability and intervenes to manage hemodynamic and mechanical problems. Of the 51 patients, 13 are still on support, 9 died before transplantation (17.6%), and post transplant survival is 96.0%. In conclusion, an active left ventricular assist device program requires skilled personnel to manage complex problems and contributes to a successful patient outcome.

State programs for medical diagnosis of child abuse and neglect: case studies of five established or fledgling programs.

OBJECTIVE: To describe the programs for medical diagnosis of child abuse and neglect in three states and efforts to establish state-wide programs in two states. To describe common themes and issues that emerged related to the establishment and maintenance of these programs. METHODS: Five states were selected as case studies to represent a range of experience and type of function embodied in programs that address medical diagnosis of child abuse and neglect. Individuals knowledgeable about the programs or efforts to establish state-wide programs in their home states described these in detail. Inductive analysis was used to identify themes and issues that emerged across the states studied. FINDINGS: Themes emerged in three general areas: funding, services, and training. Findings related to funding were: 1) State funding was vital for initiation of statewide programs; 2) Alliances with other groups with parallel interests were successfully used to garner support for child abuse programs; 3) Services needed to be adequately reimbursed to be sustained; 4) Political climate often affected funding. With regard to services we found: 1) There was no optimal way to organize services, but rather many ways that worked well; 2) It was critical to address local service needs; 3) Provision of standardized quality services was essential. With regard to training: 1) Professional training was an integral part of all statewide programs; 2) New technologies, including televideo, have been explored and implemented to assist in training in statewide programs. CONCLUSIONS: Each state has taken a unique approach to programs for the medical diagnosis of child abuse and neglect. However, there are commonalities, particularly among the states that have been successful in establishing and maintaining comprehensive services and/or training.

The role of biological control of mosquitoes in integrated vector control.

An integrated approach for the control of mosquitoes and the diseases they transmit will better enable sustainable control while helping to circumvent some of the problems associated with the use of conventional insecticides. Environmental methods and biological control are alternatives to chemical control and are key components of the integrated strategy. The use of vertebrate and invertebrate predators and entomopathogens as biological control agents and their role in integrated control programs is reviewed with emphasis on fish, Toxorhynchites mosquitoes, Notonecta species, predatory copepods, entomopathogenic bacteria, and the fungus Lagenidium giganteum. The successful implementation of these organisms will depend on an in-depth understanding of the ecology of both the targeted species and the biological control agents to be used. Thorough geographic reconnaissance will also be essential for the successful abatement of pest and vector mosquitoes. The success and sustainability of future programs, especially in developing countries, will rely not only on the use of the most appropriate technologies but also on the direct participation of the affected communities. Possible undesirable effects of biological control are also reviewed.

Achieving optimal immunization levels in school-age children.

In a school-based immunization program in four states, 70% of the students were fully immunized by the end of the first year and 85% by the end of the second year. Because of student turnover, 20% of the immunization levels achieved by the end of a school year were not sustained into the subsequent year. Levels reported by the state immunization officers were higher than those recorded by school personnel. Completed immunization series for students requiring immunizations were 33% to 40% higher for students enrolled at the start of the year than for students who entered during the school year. Students who were unimmunized at the beginning of the year had a better change (P less than 0.001) of being immunized by the end of the year than those whose immunization status was unknown. To maintain high levels, a program must be sustained and continuing, provide immunizations, and have careful administrative monitoring of child-specific population-based data. Schools are uniquely able to provide all of these elements, which can augment the efforts of private practitioners.

Gender differences in smoking cessation after 3 years in the Lung Health Study.

OBJECTIVES: An analysis of gender differences in smoking cessation was conducted among 3923 participants in the Special Intervention group of the Lung Health Study. This report focuses on gender differences in sustained quit rates at 12 and 36 months. METHODS: Special Intervention participants were offered a 12-session, 12-week smoking cessation program using nicotine gum and were followed for 3 years. Self-reported smoking status was validated with carbon monoxide and salivary cotinine. RESULTS: Men had higher sustained quit rates at 12 and 36 months; gender differences were found in baseline variables that also predicted sustained abstinence; and controlling for selected baseline variables reduced the association between gender and sustained abstinence. When other variables were controlled, gender predicted sustained abstinence at 36 months (odds ratio [OR] = 1.24, 95% confidence interval [CI] = 1.04, 1.48) but not 12 months (OR = 1.08, 95% CI = 0.92, 1.27), reflecting more late relapse among women. CONCLUSIONS: Demographics and smoking history were more important than gender per se in sustained smoking cessation in the Lung Health Study. Programs tailoring smoking cessation by gender need to include coping skills for problems associated with less education and social support and for improving persistence with quit attempts.

Developing Membership in the Education of Deaf and Hard-of-Hearing Students in Inclusive Settings.

This article discusses the importance of membership in the inclusive education of deaf/hard-of-hearing (D/HH) students. Membership refers to being an integral part of the classroom and school communities. Membership is a key philosophical concept in inclusion that may influence how classroom teachers and teachers of D/HH students share their expertise and how they work with students and each other. Membership can be contrasted with "visitorship." When programs treat D/HH students as visitors, these students face greater barriers to obtaining a quality education in classes with hearing students. A social constructivist perspective of learning and teaching that requires students in the classroom to interact with one another and the teacher may best promote learning and is consistent with a focus on membership. We suggest that inclusion is possible, but to sustain students as full members of their classes and school, programs must go beyond placement and communication access issues. To facilitate membership, inclusive programs must carefully address teacher attitudes, teacher roles and relationships, student knowledge and curriculum, structural barriers, extracurricular activities, community relationships, and parental support.

Implementation and evaluation of a neonatal educational program in rural Nepal.

A needs assessment at Tansen Mission Hospital established gaps in knowledge, skills and attitudes of health professionals, contributing to the high neonatal mortality in Nepal. This study was designed to implement and evaluate the effectiveness of an educational program in Newborn Care, using best evidence teaching methods and content. Pre intervention, an audit of newborn care practices and documentation was performed using a structured checklist. Intervention consisted of four teaching sessions each involving short lectures and interactive skills stations. Post intervention, participant satisfaction, knowledge, competence and performance were evaluated. In 80 per cent of responses (n=30), participants evaluated the program as very good or excellent. Matched pair pre and post education MCQ scores compared knowledge, with significant improvement in all groups (nurses, doctors and community health workers). Competence was evaluated by an Objective Structured Clinical Examination with mean scores (+/-SD) ranging from 65 per cent (7.0) to 87 per cent (7.3). Performance was examined by pre and post-intervention audit of records. Significant changes in practice included a 100 per cent increase in measuring length and head circumference, charting percentiles and documentation of structured history and examination in the Newborn Care Notes. Administration of vitamin K at birth increased by 71 per cent, assessment of hypoglycaemia risk by 94 per cent and those at risk of hypoglycaemia having a blood sugar level measured increased by 58 per cent. These results led to consideration of appointment of a postgraduate educator. Even with limitations in educating and implementing change in a resource limited rural setting, a short, interactive education program can have positive educational outcomes and can change practice. Sustainability is dependent on staff employing continuing education.
