Spina Bifida Global Learning Collaborative: Educating the next generation of clinicians, researchers, and advocates.

PURPOSE: This project aimed to launch an international learning community to guide the development of a spina bifida (SB) curriculum for global health trainees. METHODS: Using a descriptive study design, a convenience sample of SB curricula were identified in 2022-23 by members of the Spina Bifida World Congress Outreach Committee and evaluated during a series of monthly Zoom calls to discuss SB education in a global health context. Participants included (1) leadership from the ReachAnother Foundation, (2) invited panelists from the Spina Bifida World Congress Global Health Symposium, and (3) global health students and preceptors. Education initiatives in Ethiopia, Sweden, Argentina, Ecuador, and the United States were evaluated vis-à-vis format and content. RESULTS: All of the education initiatives referenced the framework of the World Health Organization International Classification of Functioning, Disability and Health. Formats varied and included both virtual and interactive workshops, print materials, videos, and guides for small group discussion. Content addressed four domains: Folate Prevention, Neurosurgical Training, After Care, and Data Collection. A multidisciplinary approach, partnerships with families, and workforce pipeline training were identified as guiding themes for educating the next generation of SB researchers and clinicians in global health settings. CONCLUSION: The Spina Bifida Global Learning Collaborative is a transnational group of advocates, clinicians, and investigators whose mission is the advancement of SB-related global health education. Lessons learned from the collaborative are being leveraged to develop a global health curriculum for learners, which may improve services for individuals with SB around the globe.

A case study of ReachAnother Foundation as a change champion for developing spina bifida neurosurgical care and advocating for primary prevention in Ethiopia.

Spina bifida is a serious birth defect affecting the central nervous system, characterized by incomplete closure of the neural tube. Ethiopia has a very high prevalence of spina bifida, affecting about 40 cases per 10,000 births. Babies born with spina bifida require early closure surgery, done within the first 2-3 days after birth. Some babies need repeat surgeries to address complications, including hydrocephalus. Without medical care, babies have a high risk of death within the first 5 years of their life. Neurosurgical capacity for spina bifida closure surgery at birth is a relatively new development in Ethiopia. ReachAnother Foundation, a not-for-profit organization based in OR, USA, started work in Ethiopia in 2009 and has been instrumental in training neurosurgeons and improving treatment for spina bifida and hydrocephalus. Along with the development of neurosurgical care, the Foundation has invested in training multi-disciplinary teams to conduct patient aftercare and has launched a platform for improved patient outcomes research. As of year 2022, they support six spina bifida "Centers of Excellence" nationwide and are continuously advocating for primary prevention of spina bifida through mandatory fortification of staple foods in Ethiopia. This paper describes ReachAnother's efforts in Ethiopia in a short interval of time, benefiting numerous patients and families with spina bifida and anencephaly. We document this as a case study for other countries to model where resources are limited and the prevalence of spina bifida and hydrocephalus is high, especially in Asia and Africa.

Projected impact of mandatory food fortification with folic acid on neurosurgical capacity needed for treating spina bifida in Ethiopia.

Spina bifida, also known as meningomyelocele, is a major birth defect mostly associated with folate deficiency in the mother early in pregnancy. The prevalence of spina bifida is disproportionately high in Ethiopia compared to the global average; about 10,500 liveborn are affected annually. Many affected infants do not receive timely repair surgery. There are a high number of stillbirths, and neonatal, infant, and under-five deaths. Mandatory fortification of staple foods such as wheat and maize flour with folic acid, a B vitamin, is an effective primary prevention strategy for spina bifida. Survival in those with spina bifida increases if neurosurgical intervention is available soon after birth, along with continuous surgical and clinical aftercare throughout the lifespan. Currently, Ethiopia does not have mandatory food fortification for primary prevention or adequate neurosurgical capacity to meet the need to prevent adverse outcomes associated with spina bifida. We present in this paper two concurrent and complementary policy and practice solutions occurring in Ethiopia through global partnerships: (1) capacity-building of neurosurgery care through training programs; and (2) promoting national mandatory folic acid fortification of staples for primary prevention of spina bifida. These two policy and practice interventions ensure all affected infants can receive timely pediatric neurosurgery and sustained surgical aftercare through required neurosurgeon availability, and ensure primary prevention of spina bifida. Primary prevention of spina bifida frees up significant neurosurgical capacity in resource-poor settings that can then be directed to other critical neurosurgical needs thus lowering child mortality and morbidity.

Effect of Haloperidol on Survival Among Critically Ill Adults With a High Risk of Delirium: The REDUCE Randomized Clinical Trial.

Importance: Results of studies on use of prophylactic haloperidol in critically ill adults are inconclusive, especially in patients at high risk of delirium. Objective: To determine whether prophylactic use of haloperidol improves survival among critically ill adults at high risk of delirium, which was defined as an anticipated intensive care unit (ICU) stay of at least 2 days. Design, Setting, and Participants: Randomized, double-blind, placebo-controlled investigator-driven study involving 1789 critically ill adults treated at 21 ICUs, at which nonpharmacological interventions for delirium prevention are routinely used in the Netherlands. Patients without delirium whose expected ICU stay was at least a day were included. Recruitment was from July 2013 to December 2016 and follow-up was conducted at 90 days with the final follow-up on March 1, 2017. Interventions: Patients received prophylactic treatment 3 times daily intravenously either 1 mg (n = 350) or 2 mg (n = 732) of haloperidol or placebo (n = 707), consisting of 0.9% sodium chloride. Main Outcome and Measures: The primary outcome was the number of days that patients survived in 28 days. There were 15 secondary outcomes, including delirium incidence, 28-day delirium-free and coma-free days, duration of mechanical ventilation, and ICU and hospital length of stay. Results: All 1789 randomized patients (mean, age 66.6 years [SD, 12.6]; 1099 men [61.4%]) completed the study. The 1-mg haloperidol group was prematurely stopped because of futility. There was no difference in the median days patients survived in 28 days, 28 days in the 2-mg haloperidol group vs 28 days in the placebo group, for a difference of 0 days (95% CI, 0-0; P = .93) and a hazard ratio of 1.003 (95% CI, 0.78-1.30, P=.82). All of the 15 secondary outcomes were not statistically different. These included delirium incidence (mean difference, 1.5%, 95% CI, -3.6% to 6.7%), delirium-free and coma-free days (mean difference, 0 days, 95% CI, 0-0 days), and duration of mechanical ventilation, ICU, and hospital length of stay (mean difference, 0 days, 95% CI, 0-0 days for all 3 measures). The number of reported adverse effects did not differ between groups (2 [0.3%] for the 2-mg haloperidol group vs 1 [0.1%] for the placebo group). Conclusions and Relevance: Among critically ill adults at high risk of delirium, the use of prophylactic haloperidol compared with placebo did not improve survival at 28 days. These findings do not support the use of prophylactic haloperidol for reducing mortality in critically ill adults. Trial Registration: clinicaltrials.gov Identifier: NCT01785290.

Do-not-resuscitate orders in cancer patients: a review of literature.

Discussing do-not-resuscitate (DNR) orders is part of daily hospital practice in oncology departments. Several medical factors and patient characteristics are associated with issuing DNR orders in cancer patients. DNR orders are often placed late in the disease process. This may be a cause for disagreements between doctors and between doctors and patients and may cause for unnecessary treatments and admissions. In addition, DNR orders on itself may influence the rest of the medical treatment for patients. We present recommendations for discussing DNR orders and medical futility in practice through shared decision-making. Prospective studies are needed to investigate in which a patient's cardiopulmonary resuscitation (CPR) is futile and whether or not DNR orders influence the medical care of patients.

Dutch evidence-based guidelines for amputation and prosthetics of the lower extremity: Amputation surgery and postoperative management. Part 1.

BACKGROUND: Surgeons still use a range of criteria to determine whether amputation is indicated. In addition, there is considerable debate regarding immediate postoperative management, especially concerning the use of 'immediate/delayed fitting' versus conservative elastic bandaging. OBJECTIVES: To produce an evidence-based guideline for the amputation and prosthetics of the lower extremities. This guideline provides recommendations in support of daily practice and is based on the results of scientific research and further discussions focussed on establishing good medical practice. Part 1 focuses on amputation surgery and postoperative management. STUDY DESIGN: Systematic literature design. METHODS: Literature search in five databases. Quality assessment on the basis of evidence-based guideline development. RESULTS: An evidence-based multidisciplinary guideline on amputation and prosthetics of the lower extremity. CONCLUSION: The best care (in general) for patients undergoing amputation of a lower extremity is presented and discussed. This part of the guideline provides recommendations for diagnosis, referral, assessment, and undergoing amputation of a lower extremity and can be used to provide patient information. CLINICAL RELEVANCE: This guideline provides recommendations in support of daily practice and is based on the results of scientific research and further discussions focussed on establishing good medical practice.

Dutch evidence-based guidelines for amputation and prosthetics of the lower extremity: Rehabilitation process and prosthetics. Part 2.

BACKGROUND: A structured, multidisciplinary approach in the rehabilitation process after amputation is needed that includes a greater focus on the involvement of both (para)medics and prosthetists. There is considerable variation in prosthetic prescription concerning the moment of initial prosthesis fitting and the use of replacement parts. OBJECTIVES: To produce an evidence-based guideline for the amputation and prosthetics of the lower extremities. This guideline provides recommendations in support of daily practice and is based on the results of scientific research and further discussions focussed on establishing good medical practice. Part 2 focuses on rehabilitation process and prosthetics. STUDY DESIGN: Systematic literature design. METHODS: Literature search in five databases and quality assessment on the basis of evidence-based guideline development. RESULTS: An evidence-based multidisciplinary guideline on amputation and prosthetics of the lower extremity. CONCLUSION: The best care (in general) for patients undergoing amputation of a lower extremity is presented and discussed. This part of the guideline provides recommendations for treatment and reintegration of patients undergoing amputation of a lower extremity and can be used to provide patient information. CLINICAL RELEVANCE: This guideline provides recommendations in support of daily practice and is based on the results of scientific research and further discussions focussed on establishing good medical practice.

Empowerment of people with a long-term work disability: development of the 'VrijBaan' questionnaire.

PURPOSE: To develop an instrument that measures empowerment among people with a long-term work disability. METHODS: A six-dimension empowerment model was chosen as a theoretical framework. These dimensions are as follows: competence, self-determination, meaning, impact, positive identity and group orientation. A literature search was conducted to find instruments that currently are being used to measure one or more of these constructs. Validated and applicable instruments from this search were used in a preliminary questionnaire. A pilot test was conducted consulting the target population and experts. On basis of changes from this pilot, a concept questionnaire was conducted. In a field test, this questionnaire was sent to 976 subjects who followed a vocational rehabilitation course in the years 2001-2003. Item-total correlations and factor analyses were performed on the collected data to reduce the number of items. Factor analysis was performed, and internal consistency was determined to get insight into the psychometric properties of the final questionnaire. RESULTS: From all subjects who were approached, 385 (39%) returned usable questionnaires that could be analysed. Item reduction by item-total correlations and factor analysis resulted in a final questionnaire consisting of 62 items divided over the six subscales. Internal consistency of the subscales was good: all subscales had Cronbach's alphas between 0.80 and 0.91. Some inter-correlation existed between the subscales competence, self-determination and impact. CONCLUSIONS: The 'VrijBaan' questionnaire was developed to measure empowerment among people with a long-term work disability. Although the results support the internal consistency of the subscales, further psychometric work is needed to improve the quality of this questionnaire.

Functional outcome and patient satisfaction after flexor tenotomy for plantar ulcers of the toes.

Ulcers of the toes may cause a severe physical burden, especially in patients with diabetes, in whom they occur most frequently. Several treatments have been proposed for the underlying anatomical abnormalities, but they vary in effectiveness. We evaluated our results in using flexor tenotomy to treat ulcers with underlying flexible clawing of the toes. For 42 toes from 23 patients, 15 of whom were diabetic, all ulcers healed. The mean healing time was 4 weeks (range, 1-8 weeks), the mean follow-up was 11 months (range, 1-27 months), and one recurrence and one complication occurred. Postoperative American Orthopaedic Foot Ankle Society Midfoot scores were available for 15 patients: the mean was 77 (range, 43-100). The mean visual analogue scale (VAS) for patient satisfaction increased from 3.9 points (range, 0-10 points) preoperatively to 7.7 (range, 5-10 points) postoperatively. Flexor tenotomy is a simple treatment with low complications and recurrence rates and provides good-to-excellent functional outcomes in treating flexible clawing of the toes and the associated ulceration.

A Single-Lumen Central Venous Catheter for Continuous and Direct Intra-abdominal Pressure Measurement.

BACKGROUND: Abdominal compartment syndrome (ACS) is associated with high morbidity and mortality rates. Therefore, the need for a good diagnostic tool to predict intra-abdominal hypertension (IAH) and progression to ACS is paramount. Bladder pressure (BP) has been used for several years for intra-abdominal pressure (IAP) measurement but has the disadvantage that it is not a continuous measurement. In this study, a single-lumen central venous catheter (CVC) is placed through the abdominal wall into the abdominal cavity to continuously and directly monitor the intraabdominal pressure (CDIAP). The aim of this study was to evaluate the use of CDIAP to measure BP as a representative of the true IAP. METHODS: Both BP and CDIAP were prospectively recorded on a variety of surgical patients admitted to the intensive care unit (ICU) from March 2003 up to December 2004. At the end of the surgical procedure, the CVC was placed through the abdominal wall and connected to a pressure transducer. In addition, the BP was measured through the urine drainage port after clamping the catheter and filling the bladder with 50 ml of 0.9% saline. At least three paired measurements (BP and CDIAP) were performed for at least one day on the ICU in a standardized manner at preset time intervals on each patient. The paired measurements were compared using the Bland-Altman (B-A) method. Data are presented as mean ± standard deviation. RESULTS: Over a period of 22 months (March 2003 until December 2004), 125 paired measurements of both BP and CDIAP were recorded on 25 patients. The mean age was 72.4 ± 6.6 years. Eighteen patients underwent central vascular surgery, and seven patients with peritonitis received laparotomy. The mean CDIAP was 11.4 ± 4.8 (range 2-30) mmHg, and the BP was 12.9 ± 5.3 (range 3-37) mmHg. The mean difference between CDIAP and BP was 1.6 ± 2.7 mmHg. There was an acceptable level of agreement (intraclass correlation 0.82) between IAP measured by BP and IAP measured via CDIAP. CONCLUSION: Continuous direct intra-abdominal pressure measurement proved that the BP measurement approach of Kron is representative of the IAP. CDIAP measurement is accurate and makes it easier for the nursing staff to be informed of the IAP.

Residual-limb quality and functional mobility 1 year after transtibial amputation caused by vascular insufficiency.

This study identified which residual-limb quality factors are related to functional mobility 1 year after transtibial (TT) amputation. A group of 28 TT amputees were evaluated with respect to their functional mobility (Prosthesis Evaluation Questionnaire [PEQ], Locomotor Index, Timed Up and Go test). The general (Chakrabarty score) and bony (tibial length, relative fibular length) residual-limb quality factors were assessed. An increase in general residual-limb quality (Chakrabarty >60) was correlated with greater functional mobility in one of the outcome measures (PEQ). For bony residual-limb quality, a tibial length of 12-15 cm distal from the knee joint line was correlated with greater functional outcome for all three outcome measures and the relative fibular length was not correlated with functional mobility for any of the outcome measures. This study showed that specific aspects of residual-limb quality are related to increased functional mobility. The amputation technique and resulting residual-limb factors may be important for patients to achieve functional prosthetic use.

Effects of transfusion with red cells filtered to remove leucocytes: randomised controlled trial in patients undergoing major surgery.

OBJECTIVE: To compare postoperative complications in patients undergoing major surgery who received non-filtered or filtered red blood cell transfusions. DESIGN: Prospective, randomised, double blinded trial. SETTING: 19 hospitals throughout the Netherlands (three university; 10 clinical; six general). PARTICIPANTS: 1051 evaluable patients: 79 patients with ruptured aneurysm, 412 patients undergoing elective surgery for aneurysm, and 560 undergoing gastrointestinal surgery. INTERVENTIONS: The non-filtered products had the buffy coat removed and were plasma reduced. The filtered products had the buffy coat removed, were plasma reduced, and filtered before storage to remove leucocytes. MAIN OUTCOME MEASURES: Mortality and duration of stay in intensive care. Secondary end points were occurrence of multi-organ failure, infections, and length of hospital stay. RESULTS: No significant differences were found in mortality (odds ratio for filtered v non-filtered 0.80, 95% confidence interval 0.53 to 1.21) and in mean stay in intensive care (- 0.4 day, - 1.6 to 0.6 day). In the filtered group the mean length of hospital stay was 2.4 days shorter (- 4.8 to 0.0 day; P = 0.050) and the incidence of multi-organ failure was 30% lower (odds ratio 0.70, 0.49 to 1.00; P = 0.050). There were no differences in rates of infection (0.98, 0.73 to 1.32). CONCLUSION: The use of filtered transfusions in some types of major surgery may reduce the length of hospital stay and the incidence of postoperative multi-organ failure.

Modeling and real-time prediction of classical swine fever epidemics.

We propose a new method to analyze outbreak data of an infectious disease such as classical swine fever. The underlying model is a two-type branching process. It is used to deduce information concerning the epidemic from detected cases. In particular, the method leads to prediction of the future course of the epidemic and hence can be used as a basis for control policy decisions. We test the model with data from the large 1997-1998 classical swine fever epidemic in The Netherlands. It turns out that our results are in good agreement with the data.
