Medical informatics education by medical professors within their discipline

A system for medical informatics education for medical students has been developed in the medical school. This paper describes the concept underlying the development of this system and its progressive outcomes over 8 years. In order to stimulate students to acquire computer-related knowledge and skills, this subject has been integrated into the course works of various medical subjects such as physiology. In addition, acquired knowledge and skills are evaluated within each subject by the production of reports for example, using computers. This provides a concrete example for students of the relevance of the information sciences to the solving of medical problems. A well equipped computer facility for the study of medicine also plays a significant role in inspiring student incentive. A computer room equipped with Macintosh computers was opened adjacent to the main medical library and is used in the same manner as the library, with books replaced by computers. In addition, all new students acquire their own Macintosh PowerBook. These various initiations have facilitated concept that the computer may be applied to medical problem solving at any time or place and may become as commonplace as a pen in daily medical practice.     

The Portal of Geriatrics Online Education: A 21st‐Century Resource for Teaching Geriatrics

The way students are taught and evaluated is changing, with greater emphasis on flexible, individualized, learner‐centered education, including the use of technology. The goal of assessment is also shifting from what students know to how they perform in practice settings. Developing educational materials for teaching in these ways is time‐consuming and can be expensive. The Portal of Geriatrics Online Education (POGOe) was developed to aid educators in meeting these needs and become quicker, better‐prepared teachers of geriatrics. POGOe contains more than 950 geriatrics educational materials that faculty at 45% of allopathic and 7% of osteopathic U.S. medical schools and the Centers for Geriatric Nursing Excellence have created. These materials include various instructional and assessment methodologies, including virtual and standardized patients, games, tutorials, case‐based teaching, self‐directed learning, and traditional lectures. Materials with common goals and resource types are available as selected educational series. Learner assessments comprise approximately 10% of the educational materials. POGOe also includes libraries of videos, images, and questions extracted from its educational materials to encourage educators to repurpose content components to create new resources and to align their teaching better with their learners' needs. Web‐Geriatric Education Modules, a peer‐reviewed online modular curriculum for medical students, is a prime example of this repurposing. The existence of a robust compendium of instructional and assessment materials allows educators to concentrate more on improving learner performance in practice and not simply on knowledge acquisition. It also makes it easier for nongeriatricians to teach the care of older adults in their respective disciplines.     

Sofosbuvir plus ribavirin in Japanese patients with chronic genotype 2 HCV infection: an open‐label,phase 3 trial

Genotype 2 hepatitis C virus (HCV) accounts for up to 30% of chronic HCV infections in Japan. The standard of care for patients with genotype 2 HCV – peginterferon and ribavirin for 24 weeks – is poorly tolerated, especially among older patients and those with advanced liver disease. We conducted a phase 3, open‐label study to assess the efficacy and safety of an all‐oral combination of the NS5B polymerase inhibitor sofosbuvir and ribavirin in patients with chronic genotype 2 HCV infection in Japan. We enrolled 90 treatment‐naïve and 63 previously treated patients at 20 sites in Japan. All patients received sofosbuvir 400 mg plus ribavirin (weight‐based dosing) for 12 weeks. The primary endpoint was sustained virologic response at 12 weeks after therapy (SVR12). Of the 153 patients enrolled and treated, 60% had HCV genotype 2a, 11% had cirrhosis, and 22% were over the aged 65 or older. Overall, 148 patients (97%) achieved SVR12. Of the 90 treatment‐naïve patients, 88 (98%) achieved SVR12, and of the 63 previously treated patients, 60 (95%) achieved SVR12. The rate of SVR12 was 94% in patients with cirrhosis and in those aged 65 and older. No patients discontinued study treatment due to adverse events. The most common adverse events were nasopharyngitis, anaemia and headache. Twelve weeks of sofosbuvir and ribavirin resulted in high rates of SVR12 in treatment‐naïve and previously treated patients with chronic genotype 2 HCV infection. The treatment was safe and well tolerated by patients, including the elderly and those with cirrhosis.     

Household food insecurity and future orientation of Ghanaian youth and their parents

Food insecurity heightens risk for poor mental health and psychosocial functioning. Higher levels of future orientation influence numerous desirable behaviors. However, limited evidence exists on the association between food insecurity and future orientation, particularly in low-resource settings. The objective of this study was to examine the association between food insecurity and future orientation of Ghanaian youth and their parents. The study included a cross-sectional sample of 2656 youth and 2656 parents from 8 of Ghana’s 10 regions. Food insecurity was measured using the Household Food Insecurity Access Scale. Future orientation in the Ghanaian context was measured using three distinct factors adapted from the School Success Profile and the Consideration of Future Consequences scale. We analyzed our data using hierarchical linear modeling, with a three-level linear random-intercept model with covariates. Results suggest an inverse relationship between food insecurity and future orientation of youth and their parents. Food insecurity was consistently and significantly associated with lower orientation toward success (β = ?0.18, 95% confidence interval [CI] = ?0.22, ?0.14) and higher uncertainty of the future (β = 0.22, 95% CI = 0.17, 0.28) among youth, as well as lower consideration of future consequences (β = ?0.15, 95% CI = ?0.23, ?0.06) among parents. Additionally, severe food insecurity was associated with the lowest future orientation scores for youth and their parents. Our findings indicate that, under conditions of food insecurity, youth and their parents lose sight of the future, which may come at a great cost. Encouraging individuals to engage in thinking about the future or to create future images of their selves may not be meaningful if their basic needs, including access to food, are not met. Programs that provide opportunities to generate income and accumulate assets may have a twofold effect of increasing access to food and improving future orientation.     

Immunotherapy: A new standard in the treatment of metastatic clear cell renal cell carcinoma

Renal cell cancer (RCC) represents 2%-3% of all adulthood cancers and is the most common malignant neoplasm of the kidney (90%). In the mid-nineties of the last century, the standard of treatment for patients with metastatic RCC was cytokines. Sunititib and pazopanib were registered in 2007 and 2009, respectively, and have since been the standard first-line treatment for metastatic clear cell RCC (mccRCC). Renal cell cancer is a highly immunogenic tumor with tumor infiltrating cells, including CD8+ T lymphocytes, dendritic cells, natural killer cells (NK) and macrophages. This observation led to the design of new clinical trials in which patients were treated with immunotherapy. With the growing evidence that proangiogenic factors can have immunomodulatory effects on the host’s immune system, the idea of combining angiogenic drugs with immunotherapy has emerged, and new clinical trials have been designed. In the last few years, several therapeutic options have been approved [immunotherapy and immunotherapy/tyrosine kinase inhibitors (TKI)] for the first-line treatment of mccRCC. Nivolumab/ipilimumab is approved for the treatment of patients with intermediate and poor prognoses. Several checkpoint inhibitors (pembrolizumab, nivolumab, avelumab) in combination with TKI (axitinib, lenvatinib, cabozantinib) are approved for the treatment of patients regardless of their International mRCC Database Consortium prognostic group and PD-L1 expression. There is no specific and ideal biomarker that could help in selecting the ideal patient for the appropriate first-line treatment.     

Delayed diagnosis of a retained guidewire after bedside femoral venous catheter insertion: A preventable complication

Central venous catheter (CVC) insertion is a commonly performed procedure that is used for continuous invasive hemodynamic monitoring, fluid resuscitation, drug therapy, and hemodialysis. CVC placement can be associated with serious complications that are mostly preventable. One of these complications is the loss of the guidewire within the intravascular space, which carries a high morbidity and mortality. Here, we describe a 44-year old patient who presented with acute kidney injury and metabolic derangements that necessitated bedside right femoral dialysis catheter to initiate emergent renal replacement therapy. A day after the catheter insertion, the guidewire was noted on a routine chest X-ray extending into the base of the skull. The clinical course was complicated with cerebral infarction. Subsequently, the retained guidewire was removed a few days after the CVC insertion. In summary, the retained guidewire within the circulation is associated with potentially life-threatening and hazardous outcomes. Continuing education, vigilant supervision, and implementing certain protocols are likely to prevent such undesirable events.
