The efficacy, challenges, and facilitators of telemedicine in post-treatment cancer survivorship care: an overview of systematic reviews.

BACKGROUND: Telemedicine services have been increasingly used to facilitate post-treatment cancer survivorship care, including improving access; monitoring health status, health behaviors, and symptom management; enhancing information exchange; and mitigating the costs of care delivery, especially since the COVID-19 pandemic. To inform guidance for the use of telemedicine in the post-COVID era, the aim of this overview of systematic reviews (SRs) was to evaluate the efficacy of, and survivor engagement in, telemedicine interventions in the post-treatment survivorship phase, and to consider implementation barriers and facilitators. METHODS: PubMed, Cochrane CENTRAL, CINAHL, Embase, and Web of Science databases were searched. SRs that examined the use of telemedicine in the post-treatment phase of cancer survivorship, published between January 2010 and April 2021, were included. Efficacy data were synthesized narratively. Implementation barriers and facilitators were synthesized using the Consolidated Framework for Implementation Research. RESULTS: Twenty-nine SRs were included. A substantive body of evidence found telemedicine to benefit the management of psychosocial and physical effects, particularly for improving fatigue and cognitive function. There was a lack of evidence on the use of telemedicine in the prevention and surveillance for recurrences and new cancers as well as management of chronic medical conditions. This overview highlights a range of diverse barriers and facilitators at the patient, health service, and system levels. CONCLUSIONS: This review highlights the benefits of telemedicine in addressing psychosocial and physical effects, but not in other areas of post-treatment cancer survivorship care. This large review provides practical guidance for use of telemedicine in post-treatment survivorship care.

Perceptions of aging and ageism among Mexican physicians-in-training.

INTRODUCTION: Attributing negative stereotypes to older adults (ageism) may lead to undertreatment, but little is known about the prevalence of ageism among physicians treating patients with cancer in Ibero-America. We studied stereotypes of aging among Mexican physicians-in-training. MATERIALS AND METHODS: Physicians-in-training attending an oncology meeting answered the "Negative Attributes and Positive Potential in Old Age" survey. Ten questions assessed positive characteristics of aging (PPOA; score 1-4, higher scores represent a positive perception), and four assessed negative characteristics (NAOA; score 1-4, higher score representing a negative perception). Descriptive statistics were used to analyze the questionnaires. Participants completed the "Image-of-Aging" question by writing five words describing older adults and young individuals. Each word was rated from - 5 (negative) to + 5 (positive), and presented as word clouds. RESULTS: One hundred physicians-in-training (median age 28.5) were included. For the PPOA scale, the mean score was 2.9 (SD 0.4), while for the NAOA scale it was 2.1 (SD 0.4). Perceptions of aging were better among women and trainees enrolled in geriatrics and/or oncology-related programs. In the "Image-of-Aging" questions, median rating of words describing older adults was - 2, compared to + 3 for young individuals (p < 0.001). Among words used to describe older adults, the most frequent was "frail/frailty" (n = 45), while "health" (n = 46) was the most frequent for younger individuals. CONCLUSIONS: Mexican physicians-in-training showed mostly negative perceptions of aging, exemplified by the use of negative terms to describe older adults. Creating educational initiatives aimed at decreasing ageism among oncology trainees is necessary across Ibero-America.

Cancer and aging in Ibero-America

Population aging represents a worldwide challenge. In Ibero-America (Spain, Portugal, and the American countries in which the Spanish or Portuguese language are spoken), the number of older adults is growing, leading to an increase in aging-related diseases such as cancer. Older adults already account for half of all cancer cases in Ibero-America, and this proportion will continue to increase. Furthermore, Ibero-American healthcare systems are not adequately prepared to provide care for older adults with cancer, mainly due to a lack of resources and generalized paucity of geriatric training for healthcare providers. Across the region, several clinical initiatives, educational activities and research collaborations have been established to set the foundations of Ibero-American geriatric oncology and to increase the geriatric knowledge among healthcare providers. This article provides an overview of the current landscape of geriatric oncology in Ibero-America, highlighting its critical challenges, opportunities for improvement and collaboration, and future directions

Real world patterns of care in HER2-overexpressing breast cancer: Results of a survey of TEACH clinical trial investigators in 2011.

BACKGROUND: HER2-overexpressing breast cancer (BC) is common among young patients and poses a public health burden. Adjuvant anti-HER2/neu therapy with trastuzumab reduces the risk of recurrence and improves survival. METHODS: A web-based survey was sent to 386 physicians of the "TEACH" trial in 2011 to determine access to HER2/neu testing and treatment patterns for HER2-overexpressing BC. RESULTS: There were 151 responders (39%) from 28 countries. Ninety-seven percent reported HER2/neu expression is routinely measured in their institutions by immunohistochemistry (85%), FISH (80%) and other methods (16%). Twenty percent of responders from Asia reported that the test was not routinely available. Forty-eight percent of participants reported instances when adjuvant HER2-directed therapy was recommended to a patient who eventually did not receive it. Reasons for not receiving trastuzumab was cost (73%, p < 0.0001) in low- and middle-income countries and co-morbidities in high-income countries (43%, p = 0.003). CONCLUSIONS: This survey reflects the availability of HER2/neu testing and anti-HER2/neu therapy among physicians who participated in TEACH. A high proportion of women with HER2-overexpressing BC may not receive standard adjuvant therapy due to unavailability of the test and cost of therapy. Despite having some limitations, such as a possible selection bias of participating physicians, variable definitions of access to healthcare among respondents, and changes in trastuzumab availability since 2011, our results demonstrate that access to care and region of practice impact the implementation of cancer treatments.

The Royal Philanthropic Expedition of the Vaccine: a landmark in the history of public health.

In 1979, smallpox officially became the first disease ever to be eradicated by mankind. The global efforts to defeat this dreadful pandemic, however, started almost two centuries before. One of the most important, and sometimes forgotten, events in the fight against smallpox was the Royal Philanthropic Expedition of the Vaccine, commissioned by Charles IV of Spain to physicians Francisco Xavier Balmis y Berenguer and Jose Salvany in 1804. The aim of this expedition was to take the smallpox vaccine, discovered by Jenner, to Spain's territories in the Americas and in the Far East. After several years of vaccination in modern day Puerto Rico, Cuba, Venezuela, Ecuador, Peru, Bolivia, Chile, Mexico and the Philippines, the expedition returned to Europe. To this day, the Balmis and Salvany expedition remains a great example of international cooperation, and a landmark in the history of public health.

Chlorthalidone inhibits the KvLQT1 potassium current in guinea-pig ventricular myocytes and oocytes from Xenopus laevis.

BACKGROUND AND PURPOSE: Chlorthalidone is used for the treatment of hypertension as it produces a lengthening of the cardiac action potential. However, there is no experimental evidence that chlorthalidone has electrophysiological effects on the potassium currents involved in cardiac repolarization. EXPERIMENTAL APPROACH: Ventricular myocytes and oocytes, transfected with human ionic channels that produce IK current, were exposed to different concentrations of chlorthalidone. Action potentials and potassium currents were recorded using a patch clamp technique. To determine which component of the current was affected by chlorthalidone, human channel proteins (hERG, minK and KvLQT1) were used. KEY RESULTS: Chlorthalidone prolonged the ventricular action potential at 50 and 90% by 13 and 14%, respectively. The cardiac potassium currents I(to) and IK(1) were not affected by chlorthalidone at any concentration, whereas the delayed rectifier potassium current, IK, was blocked in a dose-response, voltage-independent fashion. In our preparation, 100 microM chlorthalidone blocked the two components of the delayed rectifier potassium current with the same potency (50.1+/-5% for IK(r) and 54.6+/-6% for IK(s)) (n=7, P<0.05). The chlorthalidone-sensitive current was slow and saturated at potentials greater than +30 mV. In our conditions only the KvLQT1 potassium current was affected by the drug, by 14%. CONCLUSIONS AND IMPLICATIONS: Chlorthalidone was demonstrated to have a direct effect on cardiac ventricular myocytes; it blocked the delayed rectifier potassium current (IK), specifically the KvLQT1 component of the potassium current. These results indicate that it has potential for use as an antiarrhythmic but further studies are needed.
