Study protocol for a type-II hybrid effectiveness-implementation trial to reach teenagers using mobile money shops to reduce unintended pregnancies in Uganda.

INTRODUCTION: Unintended teenage pregnancies have become a global public health challenge, particularly in sub-Saharan Africa. There is a notably high prevalence of unintended pregnancies among unmarried teenagers in Uganda. This study will develop an intervention programme using mobile money shops (vendors) as a platform to deliver sexual and reproductive health and rights (SRHR) services to teenagers and assess its effectiveness and scalability in Uganda. METHODS AND ANALYSES: This hybrid study comprises two integral components: an intervention study to assess the effectiveness of vendor-mediated intervention and implementation research to evaluate the implementation process. 30 vendors will be recruited for both intervention and control arms in 2 municipalities in Eastern Uganda, which have a high unintended pregnancy prevalence rate among unmarried teens aged 15-19 years. A preintervention and postintervention repeated survey involving 600 participants for each arm will be conducted over 4 months. The primary outcome is the rate of condom users among teenage vendor users. The secondary outcomes include the rate of preference for receiving SRHR services at vendors and knowledge regarding SRHR. A difference-in-differences analysis will be used to determine the effectiveness of the intervention. The Bowen model will be employed to evaluate the implementation design. ETHICS AND DISSEMINATION: Ethical approval was obtained from the Ethics Review Committee of Uganda Christen University and JICA Ogata Sadako Research Institute for Peace and Development in Japan. The findings will be widely disseminated. This study was registered with the University Hospital Medical Information Network in Japan (UMIN000053332) on 12 January 2024. TRIAL REGISTRATION NUMBER: UMIN000053332.

Impact of Hospital Closure on Patients with Communicable and Non-Communicable Diseases During the COVID-19 Pandemic in Uganda: A Cross-Sectional and Mixed-Methods Study.

Background: The COVID-19 pandemic and its measures have had a profound impact on universal access to health services. We investigated the impact of the closure of the Entebbe Regional Referral Hospital (ERRH) for two years on the accessibility to necessary healthcare among non-COVID-19 patients. Methods: This mixed-methods study focused on ERRH patients with tuberculosis (TB), human immunodeficiency virus (HIV), diabetes/hypertension, and mental illness. A quantitative study used a structured-questionnaire with a primary outcome measure to assess the discontinuation of healthcare accessibility. A qualitative study with a focus group discussion (FGD) was conducted on eight patients. Results: Of the 202 quantitative survey participants, 17.8% discontinued necessary healthcare due to the ERRH closure, and the discontinuation rates differed by disease: 48.1% of TB patients, 16.0% of HIV patients, 7.8% of diabetes/hypertension patients, and 4.0% of mental health patients (P < 0.001). Almost 90% of the patients reported a worsened health condition, regardless of the disease. Multivariable logistic regression analysis showed that patients with diabetes/hypertension (adjusted odds ratio [AOR], 12.69; 95% confidence interval [CI], 2.57-62.52) and HIV (AOR, 7.52; 95% CI, 1.37-41.27) were more likely to discontinue healthcare than those with mental illness. The factors associated with discontinued healthcare included age ≥50 years vs ≤30 years (AOR, 4.88; 95% CI, 1.07-22.34), and high transportation cost vs low cost (AOR, 3.15; 95% CI, 1.13-8.75). The FGD also identified difficulties in obtaining medication, especially for TB, even though ERRH provided the outreach services. Conclusion: Our study revealed that the ERRH closure and lockdowns had an overall profound negative impact on access to healthcare and health conditions. Younger patients and those with TB were the most affected patients. This study provides practical suggestions from the field for policy makers to strengthen universal health access during health crises in Uganda and other sub-Saharan countries.

Enhancing community health system resilience: lessons learnt during the COVID-19 pandemic in Uganda through the qualitative inquiry of the COVID Task Force.

Objective: This study aimed to explore the elements of a resilient community health system during the COVID-19 pandemic and discuss whether the frameworks described in previous studies can be applied to real-world situations with those who implemented the Community Engagement Strategy, a strategy to make health systems work in their communities during health crises in Uganda. Methods: Focus group discussions (22 participants in total) were conducted with COVID Task Force members in four districts in Uganda in March 2022. These districts implemented a Community Engagement Strategy to ensure that health systems in their communities continued to function during health scares, and have been evaluated to ensure that the strategies have been implemented. Results: A thematic analysis was applied. From the results some factors which can enhance the resiliency of community health systems were identified: including health "knowledge," "communication," "governance," and "resources" health. The most important elements changed depending on the phase of the outbreak. VHTs are the key players in the transition from knowledge-and resource-oriented initiatives to communication and governance by community residents. Conclusion: COVID-19, a new infectious disease, provides lessons for a resilient community health system. First, the health system should be flexible enough to be able to change the elements on which it is focused, and second, VHTs play an important role in the flexibility of the health system. This suggests that it is time to assess whether VHTs are still able to continue their activities after the pandemic is over, and whether the environment, including financial and non-financial support, has improved.

A di-electrophoretic simulation procedure of iron-oxide micro-particle drug attachment system for leukemia treatment using COMSOL software: a potential treatment reference for LMICs.

Background: Leukemia encompasses various subtypes, each with unique characteristics and treatment approaches. The challenge lies in developing targeted therapies that can effectively address the specific genetic mutations or abnormalities associated with each subtype. Some leukemia cases may become resistant to existing treatments over time making them less susceptible to chemotherapy or other standard therapies. Objective: Developing new treatment strategies to overcome resistance is an ongoing challenge particularly in Low and Middle Income Countries (LMICs). Computational studies using COMSOL software could provide an economical, fast and resourceful approach to the treatment of complicated cancers like leukemia. Methods: Using COMSOL Multiphysics software, a continuous flow microfluidic device capable of delivering anti-leukemia drugs to early-stage leukemia cells has been computationally modeled using dielectrophoresis (DEP). Results: The cell size difference enabled the micro-particle drug attachment to the leukemia cells using hydrodynamic focusing from the dielectrophoretic force. This point of care application produced a low voltage from numerically calculated electrical field and flow speed simulations. Conclusion: Therefore, such a dielectrophoretic low voltage application model can be used as a computational treatment reference for early-stage leukemia cells with an approximate size of 5 µm.

Translating medical device innovations to market - a Ugandan perspective.

There is a disparity between low and middle-income countries (LMICs) and high-income countries (HICs) in translating medical device innovations to the market, affecting health care service delivery. Whereas medical technologies developed in HICs face substantial challenges in getting to the bedside, there are at least clear pathways in most of the major markets, such as the UK, the EU, and the USA. Much less is known about the challenges that innovators of medical technologies face in LMICs. The aim of this study was to map out current bottlenecks in medical device innovation in Uganda, a LMIC in Sub-Saharan East Africa.A cross-sectional survey was carried out using a digital questionnaire. Twenty-one individuals completed the questionnaire, with the majority being medical device innovators (n = 12). Only one of these had undertaken all the innovation stages, up to clinical validation. Very few innovators had established companies, and/or acquired intellectual property. It is evident from similar studies that challenges in medical device translations are multidimensional, and hence interdisciplinary collaborations are key to accelerating translation processes, especially for LMICs.

Repair strategies for assistive technology in low resource settings.

PURPOSE: To investigate the practices of repair that exist for users of mobility assistive products in low resource settings, as well as the psychosocial impact that the repair, or non-repair, of these devices has on users' lives. MATERIALS AND METHODS: This article collates data on repair practices and the responses from participants on the topic of repair from studies conducted by the authors across four different low resource settings in Kenya, Uganda, Sierra Leone, and Indonesia. This data was then analyzed to identify the common themes found across geographies. RESULTS: Three major models of repair practice emerged from the data: "Individual or Informal Repair in the Community"; "Local Initiatives"; and "Specialist AT Workshop Repair". Additionally, the wider impact on the participants' lives of "Problems & Concerns with Repair"; "Experiences of Breakages & Frequencies of Repair" and the "Impact of Broken Devices" are explored. CONCLUSIONS: The results of this analysis demonstrate the paramount importance of community-based repair of devices, and how despite this importance, repair is often overlooked in the planning and design of assistive products and services. There is a need to further incorporate and support these informal contributions as part of the formal provision systems of assistive device.IMPLICATIONS FOR REHABILITATIONA lack of available specialist repair services in low resource settings hinders the potential impact of assistive technology provision systems.Community-based repair is the major route by which assistive devices are repaired in low resource settings.Appropriate community-based repair strategies should be incorporated into and supported by the formal assistive technology provision models in order to optimise outcomes.A lack of data on outcomes across the lifecycle of assistive products hinders progress on improving focus on follow-up services - in particular repair & maintenance.By supporting community-based repair, repairs that are inappropriate for that approach could be better directed to specialist repair services.

Experiences of medical device innovators as they navigate the regulatory system in Uganda.

Objective: A medical device must undergo rigorous regulatory processes to verify its safety and effectiveness while in use. In low-and middle-income countries like Uganda however, medical device innovators and designers face challenges around bringing a device from ideation to being market-ready. This is mainly attributed to a lack of clear regulatory procedures among other factors. In this paper, we illustrate the current landscape of investigational medical devices regulation in Uganda. Methods: Information about the different bodies involved in regulation of medical devices in Uganda was obtained online. Nine medical device teams whose devices have gone through the Ugandan regulatory system were interviewed to gain insights into their experiences with the regulatory system. Interviews focused on the challenges they faced, how they navigated them, and factors that supported their progress towards putting their devices on the market. Results: We identified different bodies that are part of the stepwise regulatory pathway of investigational medical devices in Uganda and roles played by each in the regulatory process. Experiences of the medical device teams collected showed that navigation through the regulatory system was different for each team and progress towards market readiness was fuelled by funding, simplicity of device, and mentorship. Conclusion: Medical devices regulation exists in Uganda but is characterised by a landscape that is still in development which thereby affects the progress of investigational medical devices.

KeyLoop retractor for global gasless laparoscopy: evaluation of safety and feasibility in a porcine model.

BACKGROUND: Many surgeons in low- and middle-income countries have described performing surgery using gasless (lift) laparoscopy due to inaccessibility of carbon dioxide and reliable electricity, but the safety and feasibility of the technique has not been well documented. We describe preclinical testing of the in vivo safety and utility of KeyLoop, a laparoscopic retractor system to enable gasless laparoscopy. METHODS: Experienced laparoscopic surgeons completed a series of four laparoscopic tasks in a porcine model: laparoscopic exposure, small bowel resection, intracorporeal suturing with knot tying, and cholecystectomy. For each participating surgeon, the four tasks were completed in a practice animal using KeyLoop. Surgeons then completed these tasks using standard-of-care (SOC) gas laparoscopy and KeyLoop in block randomized order to minimize learning curve effect. Vital signs, task completion time, blood loss and surgical complications were compared between SOC and KeyLoop using paired nonparametric tests. Surgeons completed a survey on use of KeyLoop compared to gas laparoscopy. Abdominal wall tissue was evaluated for injury by a blinded pathologist. RESULTS: Five surgeons performed 60 tasks in 15 pigs. There were no significant differences in times to complete the tasks between KeyLoop and SOC. For all tasks, there was a learning curve with task completion times related to learning the porcine model. There were no significant differences in blood loss, vital signs or surgical complications between KeyLoop and SOC. Eleven surgeons from the United States and Singapore felt that KeyLoop could be used to safely perform several common surgical procedures. No abdominal wall tissue injury was observed for either KeyLoop or SOC. CONCLUSIONS: Procedure times, blood loss, abdominal wall tissue injury and surgical complications were similar between KeyLoop and SOC gas laparoscopy for basic surgical procedures. This data supports KeyLoop as a useful tool to increase access to laparoscopy in low- and middle-income countries.

Evaluation of the current status of prosthetic rehabilitation services for major limb loss: a descriptive study in Ugandan Referral hospitals.

PURPOSE: Low-and-middle-income countries (LMICs) have a large burden of major limb loss. No recent study has reported on Uganda's state of public sector prosthetics services. This study aimed to document the landscape of major limb loss, and the structure of available prosthetics services in Uganda. METHODS: This study involved a retrospective review of medical records at Mulago National Referral Hospital, Fort Portal Regional Referral Hospital, and Mbale Regional Referral Hospital, and a cross-sectional survey of personnel involved in the fabrication and fitting of prosthetic devices across orthopaedic workshops in the country. RESULTS: Upper limb amputations accounted for 14.2%, and lower limb accounted for 81.2%. Gangrene (30.3%) was the leading cause of amputation, followed by road traffic accidents and diabetes mellitus. Orthopaedic workshops offered decentralised services, and most materials used were imported. Essential equipment was largely lacking. Orthopaedic technologists had diverse experience and skill sets, but many other factors limited their service provision. CONCLUSION: The Ugandan public healthcare system lacks adequate prosthetic services both in terms of personnel and supporting resources, including equipment, materials, and components. The provision of prosthetics rehabilitation services is limited, especially in rural regions. Decentralising services could improve patients' access to prosthetic services.Implications for RehabilitationAvailability and accessibility of prosthetic services are essential to the rehabilitation and reintegration of amputees into communities in Low-and-Middle-Income countries (LMICs).For stakeholders to formulate effective plans to address issues within prosthetics service provision, quality data on the current state of services is necessary.Service providers should prioritise the decentralisation of prosthetic rehabilitation services, especially for patients in rural areas, to improve access and reach of these services.To achieve optimal limb functionality after amputation for both lower and upper limb amputees, rehabilitation professionals working in LMICs should focus on delivering comprehensive multidisciplinary rehabilitation services.Orthopaedic personnel should ensure complete and accurate documentation of patient information following amputation to enable effective tracking and monitoring of patient care to improve outcomes of rehabilitation.

Mobile Health Access and Utilisation in Uganda: Knowledge, Attitudes and Perceptions of Health and Veterinary Workers.

Background: Despite its strong growth in many parts of the world, mobile health access is still limited in low- and middle-income countries. Among the many factors restricting implementation are the lack of information security, insufficient evidence base, low sensitization, and user acceptance. Limited evidence has been obtained on current practices, perceptions, and user acceptability in such settings. The aim of this study was therefore to evaluate the knowledge, attitude, and perceptions on mobile health use among health workers and veterinary officers in Uganda. Materials and Methods: A cross-section study was carried out, targeting health practitioners in both hospitals and veterinary laboratories/clinics. A structured questionnaire was used to collect data from the Central, Eastern, Northern, and Western representative regions. Interviews with selected health workers were also conducted as well as a focused group discussion. Results: Of the 120 health practitioners that were targeted, a total of 80 health workers and 7 veterinary practitioners participated in the study of which 46% were men and 54% women. Majority of the health workers had encountered m-health but had never used it, whereas the 15 practitioners who had used it before the survey did not use it for disease diagnosis in hospitals but used it for ordering medicine online, for patient consultations with the doctors, result interpretation, tracking women menstrual cycles, tuberculosis assessment. Discussion and Conclusion: Participants expressed significant interest in mobile health as it addresses key challenges including challenges with management of patient data, and long patient queues, which would ultimately improve service delivery. However, there is some skepticism about access as many rural facilities lack access to smartphones and stable internet.

Low Cost Gastroschisis Silo for Sub-Saharan Africa: Testing in a Porcine Model.

BACKGROUND: Gastroschisis mortality in sub-Saharan Africa (SSA) remains high at 59-100%. Silo inaccessibility contributes to this disparity. Standard of care (SOC) silos cost $240, while median monthly incomes in SSA are < $200. Our multidisciplinary American and Ugandan team designed and bench-tested a low-cost (LC) silo that costs < $2 and is constructed from locally available materials. Here we describe in vivo LC silo testing. METHODS: A piglet gastroschisis model was achieved by eviscerating intestines through a midline incision. Eight piglets were randomized to LC or SOC silos. Bowel was placed into the LC or SOC silo, maintained for 1-h, and reduced. Procedure times for placement, intestinal reduction, and silo removal were recorded. Tissue injury of the abdominal wall and intestine was assessed. Bacterial and fungal growth on silos was also compared. RESULTS: There were no gross injuries to abdominal wall or intestine in either group or difference in minor bleeding. Times for silo application, bowel reduction, and silo removal between groups were not statistically or clinically different, indicating similar ease of use. Microbiologic analysis revealed growth on all samples, but density was below the standard peritoneal inoculum of 105 CFU/g for both silos. There was no significant difference in bacterial or fungal growth between LC and SOC silos. CONCLUSION: LC silos designed for manufacturing and clinical use in SSA demonstrated similar ease of use, absence of tissue injury, and acceptable microbiology profile, similar to SOC silos. The findings will allow our team to proceed with a pilot study in Uganda.

Review of investigational medical devices' clinical trials and regulations in Africa as a benchmark for new innovations.

Medical technologies present a huge potential in improving global health playing a key role toward achieving Sustainable Development Goal 3 by 2030. A number of clinicians, innovators, business entities and biomedical engineers among others have developed a number of innovative medical devices and technologies to address the healthcare challenges especially in Africa. Globally, medical devices clinical trials present the most acceptable method for determining the risks and benefits of medical device innovations with the aim of ascertaining their effectiveness and safety as compared with established medical practice. However, there are very few medical device clinical trials reported in Africa compared to other regions like USA, UK and Europe. Most of the medical device clinical trials reported in Africa are addressing challenges around HIV/AIDS, maternal health and NCDs. In this mini review, we report about some of the published medical device clinical trials in Africa PubMed and Google Scholar and their associated challenges.

The lived experience of people with upper limb absence living in Uganda: A qualitative study.

Background: The impact of upper limb absence on people's lived experiences is understudied, particularly in African countries, with implications for policy and service design. Objectives: The objective of this study was to explore the lived experiences of people with upper limb absence (PWULA) living in Uganda. Method: Informed by preliminary work, we designed a qualitative study employing semi-structured interviews to understand the experience of living with upper limb absence in Uganda. Seventeen adults with upper limb absence were individually interviewed and their interviews were analysed utilising thematic analysis. Results: Seven themes illustrating the impact on the individual's life after amputation were identified and categorised into (1) living and adapting to life, (2) productivity and participation and (3) living within the wider environment. This study presents three main findings: (1) PWULA need psychological and occupational support services which are not available in Uganda, (2) PWULA want to work, but face multiple barriers to employment and has limited support, combined with the complex parenting and caring responsibilities, (3) the local Ugandan culture and social structures affect the everyday life of PWULA, both in positive and negative ways. Conclusion: This study provides information on the lived experiences of PWULA in Uganda which are lacking in the literature. People with upper limb absence face ableism and hardship underpinned by a lack of formal support structures and policies, which may in turn exacerbate the impact of upper limb absence on multiple facets of life.

Green synthesis and characterization of iron-oxide nanoparticles using Moringa oleifera: a potential protocol for use in low and middle income countries.

OBJECTIVE: Green synthesized iron(III) oxide (Fe3O4) nanoparticles are gaining appeal in targeted drug delivery systems because of their low cost, fast processing and nontoxicity. However, there is no known research work undertaken in the production of green synthesized nano-particles from the Ugandan grown Moringa Oleifera (MO). This study aims at exploring and developing an optimized protocol aimed at producing such nanoparticles from the Ugandan grown Moringa. RESULTS: While reducing ferric chloride solution with Moringa oleifera leaves, Iron oxide nanoparticles (Fe3O4-NPs) were synthesized through an economical and completely green biosynthetic method. The structural properties of these Fe3O4-NPs were investigated by Ultra Violet-visible (UV-Vis) spectrophotometry, X-ray diffraction (XRD), energy dispersive X-ray spectroscopy (EDX) and scanning electron microscopy (SEM). These nanoparticles exhibited UV-visible absorption peaks at 225 nm (nm) for the sixth dilution and 228 nm for the fifth dilution which indicated that the nanoparticles were photosensitive and the SEM study confirmed the spherical nature of these nanoparticles. The total synthesis time was approximately 5 h after drying the moringa leaves, and the average particle size was approximately 16 nm. Such synthesized nanoparticles can potentially be useful for drug delivery, especially in Low and Middle Income Countries (LMICs).

Systems and processes for regulation of investigational medical devices in Uganda.

Background: In many parts of the world, medical devices and the processes of their development are tightly regulated. However, the current regulatory landscape in Uganda like other developing countries is weak and poorly defined, which creates significant barriers to innovation, clinical evaluation, and translation of medical devices. Aim: To evaluate current knowledge, systems and infrastructure for medical devices regulation and innovation in Uganda. Methods: A mixed methods study design using the methods triangulation strategy was employed in this study. Data of equal weight were collected sequentially. First, a digital structured questionnaire was sent out to innovators to establish individual knowledge and experience with medical device innovation and regulation. Then, a single focus group discussion involving both medical device innovators and regulators to collect data about the current regulatory practices for medical devices in Uganda. Univariate and bivariate analysis was done for the quantitative data to summarize results in graphs and tables. Qualitative data was analyzed using thematic analysis. Ethical review and approval were obtained from the Makerere University School of Biomedical Sciences, Research and Ethics Committee, and the Uganda National Council for Science and Technology. Results: A total of 47 innovators responded to the questionnaire. 14 respondents were excluded since they were not medical device innovators. Majority (76%) of individuals had been innovators for more than a year, held a bachelor's degree with a background in Engineering and applied sciences, and worked in an academic research institute. 22 of the 33 medical device innovators had stopped working on their innovations and had stalled at the proof-of-concept stage. Insufficient funding, inadequate technical expertise and confusing regulatory landscape were major challenges to innovation. The two themes that emerged from the discussion were "developing standards for medical devices regulation" and "implementation of regulations in practical processes". Legal limitations, lengthy processes, and low demand were identified as challenges to developing medical device regulations. Conclusions: Efforts have been taken by government to create a pathway for medical device innovations to be translated to the market. More work needs to be done to coordinate efforts among stakeholders to build effective medical device regulations in Uganda.

A systematic review of modeling and simulation approaches in designing targeted treatment technologies for Leukemia Cancer in low and middle income countries.

Virtual experimentation is a widely used approach for predicting systems behaviour especially in situations where resources for physical experiments are very limited. For example, targeted treatment inside the human body is particularly challenging, and as such, modeling and simulation is utilised to aid planning before a specific treatment is administered. In such approaches, precise treatment, as it is the case in radiotherapy, is used to administer a maximum dose to the infected regions while minimizing the effect on normal tissue. Complicated cancers such as leukemia present even greater challenges due to their presentation in liquid form and not being localised in one area. As such, science has led to the development of targeted drug delivery, where the infected cells can be specifically targeted anywhere in the body. Despite the great prospects and advances of these modeling and simulation tools in the design and delivery of targeted drugs, their use by Low and Middle Income Countries (LMICs) researchers and clinicians is still very limited. This paper therefore reviews the modeling and simulation approaches for leukemia treatment using nanoparticles as an example for virtual experimentation. A systematic review from various databases was carried out for studies that involved cancer treatment approaches through modeling and simulation with emphasis to data collected from LMICs. Results indicated that whereas there is an increasing trend in the use of modeling and simulation approaches, their uptake in LMICs is still limited. According to the review data collected, there is a clear need to employ these tools as key approaches for the planning of targeted drug treatment approaches.

The Evolving Landscape of Medical Device Regulation in East, Central, and Southern Africa.

Effective regulatory frameworks, harmonized to international standards, are critical to expanding access to quality medical devices in low- and middle-income countries. This review provides a summary of the state of medical device regulation in the 14 member countries of the College of Surgeons of East, Central, and Southern Africa (COSECSA) and South Africa. Countries were categorized according to level of regulatory establishment, which was found to be positively correlated to gross domestic product (GDP; rs=0.90) and years of freedom from colonization (rs=0.60), and less positively correlated to GDP per capita (rs=0.40). Although most countries mandate medical device regulation in national legislation, few employ all the guidelines set forth by the World Health Organization. A streamlined regulatory process across African nations would simplify this process for innovators seeking to bring medical devices to the African market, thereby increasing patient access to safe medical devices.

The role of medical equipment in the spread of nosocomial infections: a cross-sectional study in four tertiary public health facilities in Uganda.

BACKGROUND: With many medical equipment in hospitals coming in direct contact with healthcare workers, patients, technicians, cleaners and sometimes care givers, it is important to pay close attention to their capacity in harboring potentially harmful pathogens. The goal of this study was to assess the role that medical equipment may potentially play in hospital acquired infections in four public health facilities in Uganda. METHODS: A cross-sectional study was conducted from December 2017 to January 2018 in four public health facilities in Uganda. Each piece of equipment from the neonatal department, imaging department or operating theatre were swabbed at three distinct points: a location in contact with the patient, a location in contact with the user, and a remote location unlikely to be contacted by either the patient or the user. The swabs were analyzed for bacterial growth using standard microbiological methods. Seventeen bacterial isolates were randomly selected and tested for susceptibility/resistance to common antibiotics. The data collected analyzed in STATA version 14. RESULTS: A total of 192 locations on 65 equipment were swabbed, with 60.4% of these locations testing positive (116/192). Nearly nine of ten equipment (57/65) tested positive for contamination in at least one location, and two out of three equipment (67.7%) tested positive in two or more locations. Of the 116 contaminated locations 52.6% were positive for Bacillus Species, 14.7% were positive for coagulase negative staphylococcus, 12.9% (15/116) were positive for E. coli, while all other bacterial species had a pooled prevalence of 19.8%. Interestingly, 55% of the remote locations were contaminated compared to 66% of the user contacted locations and 60% of the patient contacted locations. Further, 5/17 samples were resistant to at least three of the classes of antibiotics tested including penicillin, glycylcycline, tetracycline, trimethoprim sulfamethoxazole and urinary anti-infectives. CONCLUSION: These results provides strong support for strengthening overall disinfection/sterilization practices around medical equipment use in public health facilities in Uganda. There's also need for further research to make a direct link to the bacterial isolates identified and cases of infections recorded among patients in similar settings.

Evaluating Reachable Workspace and User Control Over Prehensor Aperture for a Body-Powered Prosthesis.

Using a shoulder harness and control cable, a person can control the opening and closing of a body-powered prosthesis prehensor. In many setups the cable does not pass adjacent to the shoulder joint center allowing shoulder flexion on the prosthetic side to be used for prehensor control. However, this makes cable setup a difficult compromise as prosthesis control is dependent on arm posture; too short and the space within which a person can reach may be unduly restricted, too long and the user may not be able to move their shoulder sufficiently to take up the inevitable slack at some postures and hence have no control over prehensor movement. Despite the fundamental importance of reachable workspace to users, to date there have been no studies in prosthetics on this aspect. Here, a methodology is presented to quantify the reduction in the reachable volume due to the harness, and to record the range-of-motion of the prehensor at a series of locations within the reachable workspace. Ten anatomically intact participants were assessed using a body-powered prosthesis simulator. Data was collected using a 3D motion capture system and an electronic goniometer. The harnessed reachable workspace was 38-85% the size of the unharnessed volume with participants struggling to reach across the body and above the head. Across all arm postures assessed, participants were only able to achieve full prehensor range-of-motion in 9%. The methodologies presented could be used to evaluate future designs of both body-powered and myoelectric prostheses.

Technology for monitoring everyday prosthesis use: a systematic review.

BACKGROUND: Understanding how prostheses are used in everyday life is central to the design, provision and evaluation of prosthetic devices and associated services. This paper reviews the scientific literature on methodologies and technologies that have been used to assess the daily use of both upper- and lower-limb prostheses. It discusses the types of studies that have been undertaken, the technologies used to monitor physical activity, the benefits of monitoring daily living and the barriers to long-term monitoring, with particular focus on low-resource settings. METHODS: A systematic literature search was conducted in PubMed, Web of Science, Scopus, CINAHL and EMBASE of studies that monitored the activity of prosthesis users during daily-living. RESULTS: Sixty lower-limb studies and 9 upper-limb studies were identified for inclusion in the review. The first studies in the lower-limb field date from the 1990s and the number has increased steadily since the early 2000s. In contrast, the studies in the upper-limb field have only begun to emerge over the past few years. The early lower-limb studies focused on the development or validation of actimeters, algorithms and/or scores for activity classification. However, most of the recent lower-limb studies used activity monitoring to compare prosthetic components. The lower-limb studies mainly used step-counts as their only measure of activity, focusing on the amount of activity, not the type and quality of movements. In comparison, the small number of upper-limb studies were fairly evenly spread between development of algorithms, comparison of everyday activity to clinical scores, and comparison of different prosthesis user populations. Most upper-limb papers reported the degree of symmetry in activity levels between the arm with the prosthesis and the intact arm. CONCLUSIONS: Activity monitoring technology used in conjunction with clinical scores and user feedback, offers significant insights into how prostheses are used and whether they meet the user's requirements. However, the cost, limited battery-life and lack of availability in many countries mean that using sensors to understand the daily use of prostheses and the types of activity being performed has not yet become a feasible standard clinical practice. This review provides recommendations for the research and clinical communities to advance this area for the benefit of prosthesis users.
