Background: The practice of pathology in the developing world presents challenges in terms of limited resources, shortages of trained personnel, and lack of continuing education programs. Telepathology holds promise as a means of diagnostic and educational support.Methods: We donated multiheaded teaching microscopes equipped with digital cameras to four hospitals in Eastern Africa and trained local pathologists on their use. Static images of challenging cases were posted on a web-based telepathology platform. A U.S.-based pathologist reviewed images in consultation with subspecialist colleagues.Results: Over a period of 40 months, 109 cases were submitted for second opinion consultation, including 29 dermatopathology cases (26.6%), 14 hematopathology cases (12.8%), and 13 cases each (11.9%) in cytopathology and bone and soft tissue pathology. Static images enabled a complete or partial diagnosis in 100/109 cases (91.7%). Factors precluding a definitive diagnosis included absence of confirmatory immunophenotyping, technical issues, or lack of clinical history. Case responses included a diagnosis and discussion, including differential diagnosis, references, and treatment recommendations.Conclusion: Static digital telepathology is a simple, cost-effective, reliable and efficient means to provide diagnostic and educational support to pathologists in the developing world. Additional training may help overcome technical factors precluding a definitive diagnosis in certain cases.

OBJECTIVE Pediatric neurosurgery can be highly cost-effective even in the developing world, but delivery of these services is hampered by resource limitations at the levels of both health care infrastructure and individual patients. Few studies have evaluated costs borne by neurosurgical patients in the developing world and their potential implications for efficient and effective delivery of care in this population. METHODS The families of 40 pediatric neurosurgery patients were surveyed in February 2015 at the AIC Kijabe Hospital in Kijabe, Kenya. Costs associated with obtaining inpatient care were assessed. RESULTS Patient families were charged an average of US $539.44 for neurosurgical services, representing 132% of their annual income. Indirect expenses (transport, food and lodging, lost wages) constituted US $79.37, representing 14.7% of the overall cost and 19.5% of their annual income. CONCLUSIONS Expansion of pediatric neurosurgical services throughout the developing world necessitates increased attention to seemingly insignificant expenses that are absorbed by patients and their families. Even when all direct costs are covered at the institutional or national level, without additional assistance, some patients may be too poor to obtain even “free” neurosurgical care.

To identify and localize an intraorbital wooden foreign body is often a challenging radiological issue; delayed diagnosis can lead to serious adverse complications. Preliminary radiographic interpretations are often integrated with computed tomography and magnetic resonance, which play a crucial role in reaching the correct definitive diagnosis. We report on a 40 years old male complaining of pain in the right orbit referred to our hospital for evaluation of eyeball pain and double vision with an unclear clinical history. Computed tomography and magnetic resonance scans supposed the presence of an abscess caused by a foreign intraorbital body, confirmed by surgical findings.

Background: Pediatric hydrocephalus is one of the most common neurosurgical conditions and is a major contributor to the global burden of surgically treatable diseases. Methods: The authors conducted a literature review around the topic of pediatric hydrocephalus in the context of global surgery, the unique challenges to creating access to care in low-income countries, and current international efforts to address the problem. Results: Developing countries face the greatest burden of pediatric hydrocephalus due to high birth rates and greater risk of neonatal infections. This burden is related to more general global health challenges, including malnutrition, infectious diseases, maternal and perinatal risk factors, and education gaps. Unique challenges pertaining to the treatment of hydrocephalus in the developing world include a preponderance of postinfectious hydrocephalus, limited resources, and restricted access to neurosurgical care. In the 21st century, several organizations have established programs that provide hydrocephalus treatment and neurosurgical training in Africa, Central and South America, Haiti, and Southeast Asia. These international efforts have employed various models to achieve the goals of providing safe, sustainable, and cost-effective treatment. Conclusions: Broader commitment from the pediatric neurosurgery community, increased funding, public education, surgeon training, and ongoing surgical innovation will be needed to meaningfully address the global burden of untreated hydrocephalus.

Abstract This paper describes a web-based process/material advisory system that can be used during conceptual design. Given a set of design requirements for a part during conceptual design stage, our system produces process sequences that can meet the design requirements. Quite often during conceptual design stage, design requirements are not precisely defined. Therefore, we allow users to describe design requirements in terms of parameter ranges. Parameter ranges are used to capture uncertainties in design requirements. Our system accounts for uncertainties in design requirements in generating and evaluating process/material combinations. Our system uses a two step algorithm. During the first step, we generate a material/process option tree. This tree represents various process/material options that can be used to meet the given set of design requirements. During the second step, we evaluate various alternative process/material options using a depth first branch and bound algorithm to identify and recommend the least expensive process/material combination to the designer. Our system can be accessed on the World Wide Web using a standard browser. Our system allows designs to consider a wide variety of process/material options during the conceptual design stage and allows them to find the most cost-effective combination. By selecting the process/material combination during the early design stages, designers can ensure that the detailed design is compatible with all of the process constraints for the selected process.

AbstractWalk-sharing is a cost-effective and proactive approach that promises to improve pedestrian safety and has been shown to be technically (theoretically) viable. Yet, the practical viability of walk-sharing is largely dependent on community acceptance, which has not, until now, been explored. Gaining useful insights on the community’s spatio-temporal and social preferences in regard to walk-sharing will ensure the establishment of practical viability of walk-sharing in a real-world urban scenario. We aim to derive practical viability using defined performance metrics (waiting time, detour distance, walk-alone distance and matching rate) and by investigating the effectiveness of walk-sharing in terms of its major objective of improving pedestrian safety and safety perception. We make use of the results from a web-based survey on the public perception on our proposed walk-sharing scheme. Findings are fed into an existing agent-based walk-sharing model to investigate the performance of walk-sharing and deduce its practical viability in urban scenarios.

Jeffrey Stiles pondered these seemingly straightforward questions. As IT Director of Jagged Peak, Inc., a developer of e-commerce solutions located in the Tampa Bay region of Florida, it would be his responsibility to oversee the implementation of security measures that went beyond the existing user name and password currently required for each user. Recent events suggested that a move towards increased security might be inevitable. In just the past year, highly publicized security failures at the U.S. Department of Defense, major healthcare providers and large companies, such as Sony and JP Morgan Chase, had made executives acutely aware of the adverse consequences of IT system vulnerabilities. In fact, a study of business risk managers conducted in 2014 found that 69% of all businesses had experienced some level of hacking in the previous year. The nature of Jagged Peak’s business made the security of its systems a particular concern. The company, which had grown rapidly over the years, reporting over $61 million in revenue in 2014, provided its customers with software that supported web-based ordering, fulfillment and logistics activities, built around a philosophy of “buy anywhere, fulfill anywhere, return anywhere”. To support these activities, the company’s Edge platform needed to handle a variety of payment types, including gift cards (a recent target of hackers), as well as sensitive personal identifying information (PII). Compounding the security challenge: each customer ran its own instance of the Edge platform, and managed its own users. When only a single customer was being considered, the addition of further layers of security to authenticate uses was an eminently solvable problem. A variety of alternative approaches existed, including the use of various biometrics, key fobs that provided codes the user could enter, personalized security questions, and many others. The problem was that where multiple customers were involved, it was much more difficult to form a consensus. One customer might object to biometrics because it users lacked the necessary hardware. Another might object to security keys as being too costly, easily stolen or lost. Personalized questions might be considered too failure-prone by some customers. Furthermore, it was not clear that adding additional layers of authentication would necessarily be the most cost-effective way to reduce vulnerability. Other approaches, such as user training might provide greater value. Even if Stiles decided to proceed with additional authentication, questions remained. Mandatory or a free/added-cost option? Developed in house or by a third party? Used for internal systems only, customer platforms only, or both? Implementation could not begin until these broad questions were answered.

The Swinfen Charitable Trust was established in 1998 with the aim of helping the poor, sick and disabled in the developing world. It does this by setting up simple telemedicine links based on e-mail to support doctors in isolated hospitals. The first telemedicine link was established to support the lone orthopaedic surgeon at the Centre for the Rehabilitation of the Paralysed (CRP) in Savar, near Dhaka in Bangladesh in July 1999. An evaluation of the 27 referrals made during the first year of operation showed that the telemedical advice had been useful and cost effective. Based on the success of the Bangladesh project, the Swinfen Charitable Trust supplied digital cameras and tripods to more hospitals in other developing countries. These are Patan Hospital in Nepal (March 2000), Gizo Hospital in the Solomon Islands (March 2000), Helena Goldie Hospital on New Georgia in the Solomon Islands (September 2000), and LAMB Hospital in Bangladesh (September 2000).

BackgroundWeb-based interventions are effective in reducing depression. However, the evidence for the cost-effectiveness of these interventions is scarce.AimsThe aim is to assess the cost-effectiveness of a web-based intervention (GET.ON M.E.D.) for individuals with diabetes and comorbid depression compared with an active control group receiving web-based psychoeducation.MethodWe conducted a cost-effectiveness analysis with treatment response as the outcome and a cost-utility analysis with quality-adjusted life-years (QALYs) alongside a randomised controlled trial with 260 participants.ResultsAt a willingness-to-pay ceiling of €5000 for a treatment response, the intervention has a 97% probability of being regarded as cost-effective compared with the active control group. If society is willing to pay €14 000 for an additional QALY, the intervention has a 51% probability of being cost-effective.ConclusionsThis web-based intervention for individuals with diabetes and comorbid depression demonstrated a high probability of being cost-effective compared with an active control group.Declaration of interestS.N., D.D.E., D.L., M.B. and B.F. are stakeholders of the Institute for Online Health Trainings, which aims to transfer scientific knowledge related to this research into routine healthcare.

Background: Lipopeptides are potential microbial metabolites that are abandoned with broad spectrum biopharmaceutical properties ranging from antimicrobial, antiviral and anticancer, etc. Clinical studies are not much explored beyond the experimental methods to understand drug mechanisms on target proteins at the molecular level for large molecules. Due to the less available studies on potential target proteins of lipopeptide based drugs, their potential inhibitory role for more obvious treatment on disease have not been explored in the direction of lead optimization. However, Computational approaches need to be utilized to explore drug discovery aspects on lipopeptide based drugs, which are time saving and cost-effective techniques. Methods: Here a ligand-based drug discovery approach is coupled with reverse pharmacophore-mapping for the prediction of potential targets for antiviral (SARS-nCoV-2) and anticancer lipopeptides. Web-based servers PharmMapper and Swiss Target Prediction are used for the identification of target proteins for lipopeptides surfactin and iturin produced by Bacillus subtilis. Results: The studies have given the insight to treat the diseases with next-generation large molecule therapeutics. Results also indicate the affinity for Angiotensin-Converting Enzymes (ACE) and proteases as the potential viral targets for these categories of peptide therapeutics. A target protein for the Human Papilloma Virus (HPV) has also been mapped. Conclusion: The work will further help in exploring computer-aided drug designing of novel compounds with greater efficiency where the structure of the target proteins and lead compounds are known.
