RESUMO

BACKGROUND: Distribution of long-lasting insecticide treated nets (LLINs) is the most widely used intervention for the prevention of malaria but recall and social desirability biases may lead to challenges in accurately measuring use of bednets. SmartNet is a remote electronic monitor that provides objective measurements of bednet use over weeks at a time. Assessing local acceptability is important when implementing innovative global health technologies such as SmartNet. This study draws on established models such as the Technology Acceptance Model (TAM) and Theoretical Framework of Acceptability (TFA) to assess acceptability of SmartNet in Ugandan households. METHODS: Semi-structured qualitative interviews were conducted at weeks one and six following installation of SmartNet in ten households in Western Uganda. Heads-of-households answered open-ended questions addressing the main acceptability domains of the TFA and TAM models (i.e. perceived ease of use, ethicality, etc.). Responses were digitally recorded, transcribed, coded and analyzed using a thematic analysis approach. RESULTS: Seven out of ten households interviewed reported no difference in use between SmartNet and a standard LLIN. Households stated the large size, soft fabric, and the efficacy of SmartNet relative to a standard LLIN contributed to perceived usefulness and perceived ease of use. Opportunity costs of the novel monitoring system expressed by households included difficulty washing nets and dislike of blinking lights on the device. Barriers to SmartNet use focused on questions of the ethics of bednet use monitoring, discomfort with technical aspects of the device and a poor understanding of its function amongst others in the community. However, explaining SmartNet to other community members resolved these concerns and often resulted in interest and acceptance among peers. CONCLUSION: Objective monitoring of bednet use with SmartNet appears acceptable to these households in Uganda. Use of SmartNet seems to be similar to behaviors around use of standard LLINs. Viewpoints on many aspects of SmartNet were generally favorable. Concerns around ethicality of bednet monitoring are present and indicate the need for continuing community education. The device will continue to be optimized to make it more acceptable to users and to accurately reflect standard LLIN use to improve our understanding of prevention behaviors in malaria endemic settings.

RESUMO

BACKGROUND: Intrapartum-related hypoxic events are a major cause of morbidity and mortality in low resource countries. Neonates who receive proper resuscitation may go on to live otherwise healthy lives. However, even when a birth attendant is present, these babies frequently receive suboptimal ventilation with poor outcomes. The Augmented Infant Resuscitator (AIR) is a low-cost, reusable device designed to provide birth attendants real-time objective feedback on measures of ventilation quality during resuscitations and is intended for use in training and at the point of care. The goal of our study was to determine the impact and cost-effectiveness of AIR deployment in conjunction with existing resuscitation training programs in low resource settings. METHODS: We developed a simulation model of the natural history of intrapartum-related neonatal hypoxia and resuscitation deriving parameters from published literature and model calibration. Simulations estimated the number of disability-adjusted life years (DALYs) averted with use of the AIR by birth attendants if deployed at the point of care. Potential decreases in neonatal mortality and long-term subsequent morbidity from disability were modeled over a lifetime horizon. The primary outcome for the analysis was the cost per DALY averted. Model parameters were specific to the Mbeya region of Tanzania. RESULTS: Implementation of the AIR strategy resulted in an additional cost of $24.44 (4.80, 73.62) per DALY averted on top of the cost of existing, validated resuscitation programs. Per hospital, this adds an extra $656 to initial training costs and averts approximately 26.84 years of disability in the cohort of children born in the first year, when projected over a lifetime. The findings were robust to sensitivity analyses. Total roll-out costs for AIR are estimated at $422,688 for the Mbeya region, averting approximately 9018 DALYs on top of existing resuscitation programs, which are estimated to cost $202,240 without AIR. CONCLUSION: Our modeling analysis finds that use of the AIR device may be both an effective and cost-effective tool when used as a supplement to existing resuscitation training programs. Implementation of this strategy in multiple settings will provide data to improve our model parameters and potentially confirm our findings.

RESUMO

Medical technology offers enormous potential for scalable medicine--to improve the quality and access in health care while simultaneously reducing cost. However, current medical device innovation within companies often only offers incremental advances on existing products, or originates from engineers with limited knowledge of the clinical complexities. We describe how the Hacking Medicine Initiative, based at Massachusetts Institute of Technology has developed an innovative "healthcare hackathon" approach, bringing diverse teams together to rapidly validate clinical needs and develop solutions. Hackathons are based on three core principles; emphasis on a problem-based approach, cross-pollination of disciplines, and "pivoting" on or rapidly iterating on ideas. Hackathons also offer enormous potential for innovation in global health by focusing on local needs and resources as well as addressing feasibility and cultural contextualization. Although relatively new, the success of this approach is clear, as evidenced by the development of successful startup companies, pioneering product design, and the incorporation of creative people from outside traditional life science backgrounds who are working with clinicians and other scientists to create transformative innovation in health care.

RESUMO

OBJECTIVES: Effective bag-valve-mask ventilation is critical for reducing perinatal asphyxia-related neonatal deaths; however, providers often fail to achieve and maintain effective ventilation. The Augmented Infant Resuscitator (AIR) attaches to bag-valve-masks and provides visual feedback on air leaks, blocked airways, harsh breaths, and improper ventilatory rates. We evaluated the effect of this real-time-digital feedback on ventilation quality and the effective determination of airway integrity in a randomized controlled study in Uganda and the United States. METHODS: Birth attendants trained in newborn resuscitation were randomized to receive either real-time AIR device feedback (intervention) or no feedback (control) during ventilation exercises. Intervention-arm participants received a 2-minute orientation on interpreting AIR feedback using a single-page iconography chart. All participants were randomly assigned to 3 blinded ventilation scenarios on identical-appearing manikins with airways that were either normal, significantly leaking air, or obstructed. RESULTS: We enrolled 270 birth attendants: 77.8% from Uganda and 22.2% from the United States. Birth attendants receiving AIR feedback achieved effective ventilation 2.0 times faster: intervention mean 13.8s (95% confidence interval 10.6-17.1) versus 27.9s (21.6-34.3) for controls (P < .001). The duration of effective ventilation was 1.5 times longer: intervention mean 72.1s (66.7-77.5) versus 47.9s (41.6-54.2) for controls (P < .001). AIR feedback was associated with significantly more accurate and faster airway condition assessment (intervention mean 43.7s [40.5-47.0] versus 55.6s [51.6-59.6]). CONCLUSIONS: Providers receiving real-time-digital AIR device feedback achieved effective ventilation significantly faster, maintained it longer, and determined airway condition faster and more accurately than providers in the control group.

RESUMO

Severe acute respiratory syndrome coronavirus (SARS-CoV-2), causative agent of coronavirus disease 2019 (COVID-19), binds via ACE2 receptors, highly expressed in ciliated cells of the nasal epithelium. Micro-optical coherence tomography (µOCT) is a minimally invasive intranasal imaging technique that can determine cellular and functional dynamics of respiratory epithelia at 1-µm resolution, enabling real time visualization and quantification of epithelial anatomy, ciliary motion, and mucus transport. We hypothesized that respiratory epithelial cell dysfunction in COVID-19 will manifest as reduced ciliated cell function and mucociliary abnormalities, features readily visualized by µOCT. Symptomatic outpatients with SARS-CoV-2 aged ≥ 18 years were recruited within 14 days of symptom onset. Data was interpreted for subjects with COVID-19 (n=13) in comparison to healthy controls (n=8). Significant reduction in functional cilia, diminished ciliary beat frequency, and abnormal ciliary activity were evident. Other abnormalities included denuded epithelium, presence of mucus rafts, and increased inflammatory cells. Our results indicate that subjects with mild but symptomatic COVID-19 exhibit functional abnormalities of the respiratory mucosa underscoring the importance of mucociliary health in viral illness and disease transmission. Ciliary imaging enables investigation of early pathogenic mechanisms of COVID-19 and may be useful for evaluating disease progression and therapeutic response.

RESUMO

Postictal psychosis (PIP) in patients with epilepsy is often mistaken for other primary psychiatric disorders. Depending on its severity, PIP often prompts empiric treatment with atypical antipsychotics, which are balanced against the risk of lowered seizure thresholds. Here we present a case of olanzapine-resistant PIP, where risperidone was used as a safe and effective abortive treatment.

RESUMO

A 69-year-old man with irritable bowel syndrome on a restricted diet presented with fatigue, myalgias, extensive bilateral lower-extremity petechiae and ecchymoses, transfusion-refractory anemia, and elevated inflammatory markers. A low serum vitamin C level led to the diagnosis of scurvy. This is the first reported case of vitamin C deficiency and clinical scurvy related to voluntary dietary restriction from irritable bowel syndrome in an adult patient.

RESUMO

BACKGROUND: Healthcare-focused hackathons are 48-hour platforms intended to accelerate novel medical technology. However, debate exists about how much they contribute to medical technology innovation. The Consortium for Affordable Medical Technologies (CAMTech) has developed a three-pronged model to maximise their effectiveness. To gauge the success of this model, we examined follow-up outcomes. METHODS: Outcomes of 12 hackathons from 2012 to 2015 in India, Uganda and the USA were measured using emailed surveys. To minimise response bias, non-responding teams were coded as having made no progress. RESULTS: 331 individuals provided information on 196 of 356 projects (55.1% response rate), with no difference in responses from teams participating in different countries (Cramer's V=0.09, p=0.17). 30.3% of projects had made progress after a mean of 12.2 months. 88 (24.7%) teams had initiated pilot testing, with 42 (11.8%) piloting with care providers and 24 (6.7%) with patients. Overall, 97 teams (8.1 per hackathon) drafted business plans, 22 (1.8 per hackathon) had filed patents on their innovations and 15 (1.3 per hackathon) had formed new companies. Teams raised US$64.08 million in funding (average US$5.34 million per hackathon; median award size of $1800). In addition, 108 teams (30.3%) reported at least one member working on additional technologies with people they met at a hackathon. Individual confidence to address medical technology challenges was significantly increased after attending (t(1282)=192.77, p 0.001). CONCLUSION: CAMTech healthcare hackathons lead to consistent output with respect to medical technology innovation, including clinical trials, business plan development, securing investment capital/funding and new company formation.

RESUMO

Responding to disparities in health, thousands of health care providers volunteer annually for short-term medical service trips (MSTs) to serve communities in need as a result of environmental, geographic, historical, or sociopolitical factors. Although well intentioned, short-term MSTs have the potential to benefit and harm those involved, including participants and communities being served. The contexts, resource and time limitations, and language and cultural barriers present ethical challenges. There have been increasing requests for standardized global guidelines, transparency, and open review of MSTs and their outcomes. Principles of mission, partnership, preparation, reflection, support, sustainability, and evaluation inform and equip those engaging in medical volunteerism.

RESUMO

OBJECTIVES: Newborn deaths comprise an alarming proportion of under-five mortality globally. In this retrospective cohort study, we investigated the effectiveness of focused newborn resuscitation training and delivery of a positive-pressure device in a rural midwife population in a low-resource setting. The present research attempts to better understand the extent to which knowledge and self-efficacy contribute to resuscitation attempts by birth attendants in practice. METHODS: A one-year retrospective cohort analysis was undertaken in Aceh, Indonesia of two groups of community-based midwives, one having received formal training and a positive-pressure resuscitative device and the other receiving usual educational resources and management. A path analysis was undertaken to evaluate relative determinants of actual resuscitation attempts. RESULTS: 348 community-based midwives participated in the evaluation and had attended 3116 births during the preceding year. Path analysis indicated that formal training in resuscitation and delivery of a positive-pressure device were significantly related to both increased knowledge (ß=0.55, p=0.001) and increased self-efficacy (ß=0.52, p=0.001) in performing neonatal resuscitations with a positive-pressure device. However, training impacted actual resuscitation attempts only indirectly through a relationship with self-efficacy and with knowledge. Combined across groups, self-efficacy was significantly associated with positive pressure ventilation attempts (ß=0.26, p<0.01) whereas knowledge was not (ß=-0.05, p=0.39). CONCLUSION: Although, to date, evaluations of newborn resuscitation programs have primarily focused on training and has reported process indicators, these results indicate that in order to improve intrapartum-related hypoxic events ("birth asphyxia"), increased emphasis should be placed on participant self-efficacy and mastery of newborn resuscitation.

RESUMO

OBJECTIVE: To evaluate a birth asphyxia management program among community midwives in a low-resource rural setting. METHODS: Concise training with provision of positive-pressure ventilation devices was implemented in Indonesia in 2005. The effectiveness of the intervention among community-based midwives between October 2007 and September 2008 was evaluated. The intervention cohort was compared with a neighboring control cohort. RESULTS: Overall, 242 intervention and 106 control midwives were surveyed. In total, 3116 births were attended, 84.0% of deliveries occurred at home, and 97.4% of midwives had not previously owned a resuscitation device. When positive-pressure ventilation was administered, newborn survival on day 1 was equivalent in the 2 cohorts (88.4% versus 84.4%; P=0.66). However, significantly more newborns in the intervention group underwent ventilation (risk ratio 2.3; 95% confidence interval, 1.4-8.0). The intervention group had significantly greater scores on both knowledge (t[144.35]=10.52; P<0.001) and confidence (t[134.17]=11.66; P<0.001). CONCLUSION: Focused community-based resuscitation training and device delivery resulted in a significantly increased proportion of newborns receiving life-saving positive-pressure breaths, in addition to improved provider knowledge and confidence. Furthermore, the program demonstrated the establishment of an effective training infrastructure within a disrupted health system.

RESUMO

A clinical gap remains between the need for and the availability of functioning incubators to address the burden of neonatal mortality in poor settings. Increased referral capacity and demand for facility-based deliveries will necessitate enhanced care capacity. Rapid dysfunction of donated equipment is not only demoralizing to providers and patient families, but also presents a disincentive for timely referral to facilities. We expect a sustainable incubator that meets target clinical needs can serve as a training catalyst for providers to learn aspects along the continuum of newborn care. Many of these skills either do not require or may obviate the need for a newborn to be in such a device. Far from being a competitor to functioning approaches to thermo-regulation in resource-limited settings, a high- functioning and sustainable device targeted for district level hospitals can work collaboratively along the continuum of newborn care. Meeting this need will help ensure survival of imminently preventable causes of childhood mortality.
