Abstract 9 Cancer kills more people worldwide than HIV/AIDS, tuberculosis, and malaria combined, and low- and middle-income countries (LMICs) bear the majority of this burden. While success in detection, diagnosis, and treatment has been reported in LMICs through the use of low-cost, point-of-care (POC) technologies, this area has been largely overlooked by the medical device industry and venture capital communities, as low-cost solutions offer less financial incentive for investment. The program presented here aims to simplify the pathway to market by funding investigation teams to adapt and validate existing technologies in low-resource settings. This program specifically supports the translation of these technologies, prioritizing patient outcomes in a manner not typically seen. This program, currently in its second year, will soon support 15 technologies for cancer detection, diagnosis, and treatment (e.g., in vitro assays, imaging devices, ablation devices). It is anticipated that by year seven of the program, at least nine projects will have progressed through optimization, clinical validation, and business planning for dissemination and commercialization. Each project consists of an adaptation phase (two years: $500k total costs/year) and validation phase (three years: $1M total costs/year). Projects are selected through the National Institutes of Health peer review process by a special emphasis panel briefed on the goals of the program. Projects are competitively vetted for Phase II funding based on completion of Phase I milestones. All teams contain expertise in engineering, oncology, and business/manufacturing, uniquely leveraging their devices for success in translation. The seven preliminarily funded projects are making strides in optimization, and the projects range from an LED-based photodynamic therapy device for oral cancer to POC tests for Hepatitis C viral antigen level and viral load detection. This program is funded by the National Cancer Institute and the National Institute of Biomedical Imaging and Bioengineering at the National Institutes of Health.

Endometrial cancer is the most common malignancy of the female genital tract and a major cause of morbidity and mortality in women. Early detection is key to ensuring good outcomes but a lack of minimally invasive screening tools is a significant barrier. Most endometrial cancers are obesity-driven and develop in the context of severe metabolomic dysfunction. Blood-derived metabolites may therefore provide clinically relevant biomarkers for endometrial cancer detection. In this study, we analysed plasma samples of women with body mass index (BMI) ≥ 30 kg/m2 and endometrioid endometrial cancer (cases, n = 67) or histologically normal endometrium (controls, n = 69), using a mass spectrometry-based metabolomics approach. Eighty percent of the samples were randomly selected to serve as a training set and the remaining 20% were used to qualify test performance. Robust predictive models (AUC > 0.9) for endometrial cancer detection based on artificial intelligence algorithms were developed and validated. Phospholipids were of significance as biomarkers of endometrial cancer, with sphingolipids (sphingomyelins) discriminatory in post-menopausal women. An algorithm combining the top ten performing metabolites showed 92.6% prediction accuracy (AUC of 0.95) for endometrial cancer detection. These results suggest that a simple blood test could enable the early detection of endometrial cancer and provide the basis for a minimally invasive screening tool for women with a BMI ≥ 30 kg/m2.

Early diagnosis and treatment have always been highly desired in the fight against cancer, and detection of circulating tumor DNA (ctDNA) has recently been touted as highly promising for early cancer screening. Consequently, the detection of ctDNA in liquid biopsy gains much attention in the field of tumor diagnosis and treatment, which has also attracted research interest from the industry. However, traditional gene detection technology is difficult to achieve low cost, real-time and portable measurement of ctDNA. Electroanalytical biosensors have many unique advantages such as high sensitivity, high specificity, low cost and good portability. Therefore, this review aims to discuss the latest development of biosensors for minimal-invasive, rapid, and real-time ctDNA detection. Various ctDNA sensors are reviewed with respect to their choices of receptor probes, detection strategies and figures of merit. Aiming at the portable, real-time and non-destructive characteristics of biosensors, we analyze their development in the Internet of Things, point-of-care testing, big data and big health.

AbstractPectus carinatum has traditionally been described as a rare chest wall anomaly in comparison to pectus excavatum. However, recent data from chest wall anomaly clinics demonstrate that this deformity is probably much more frequent than once believed. In the past, invasive surgical correction by the Ravitch technique was essentially the only option for treatment of pectus carinatum. Major advances over the past two decades have provided additional options, including noninvasive chest wall bracing and minimally invasive surgical correction. This article will discuss current options for the treatment of pectus carinatum, and some of the factors that should be taken into account when choosing the options available. Diagnosis and treatment of the pectus arcuatum variant will also be described.
