RESUMEN
Background: Besides its role in calcium homeostasis and bone mineralization, vitamin D may also reduce the risk of cancer, cardiovascular and autoimmune diseases. Excessive vitamin D intake can lead to life-threatening hypercalcemia and toxicity, however. Here, we wanted to determine the relative search volume (RSV) of interest in vitamin D and its adverse biological effects (hypercalcemia, renal failure, kidney stones, bone density).Methods: We used data from Google Trends to assess changes in RSV trends across the world's regions. Data were extracted via the search terms "cholecalciferol", "ergocalciferol, "hypercalcemia", "acute renal failure", "kidney stones", and "bone density" from queries in English from 1 January 2004 to 1 October 2018 in the tool's related query database. Statistical analysis was performed using SPSS (R) 22.0 for Windows (IBM Inc., Armonk, NY, USA, 10504-1722).Results: There was a correlation between the RSV of cholecalciferol and ergocalciferol (Spearman's correlation) and the RSV of hypercalcemia, renal failure, kidney stones, and bone density. As measured by the change in RSV score, the trend for interest in kidney stones increased more rapidly than that for the other search terms. There was a positive correlation between the RSV score for cholecalciferol (or ergocalciferol) and renal failure and between the RSV score for cholecalciferol (or ergocalciferol) and kidney stones, whereas there was a negative correlation between cholecalciferol and hypercalcemia. The interest of ergocalciferol increased in parallel with the interest in bone density. The highest concentration of interest in cholecalciferol occurred in North America, Europe, India and Australia, whereas interest in ergocalciferol was greater in Central and South America, Spain, and Thailand. Interest in kidney stones was greater than cholecalciferol in North America, Brazil, India, and Australia, while interest in bone density was greater than cholecalciferol in North America, Brazil, Italy, Spain, South Africa, and Australia.Conclusions: In the pre-pandemic COVID-19 (COronaVIrus Disease 19) era, our preliminary results showed a positive correla-tion between global interest in cholecalciferol and kidney stones and renal failure, respectively. However, we found an unexpected negative correlation between global interest in cholecalciferol and hypercalcemia. Additionally, we found a positive correlation between global interest in ergocalciferol and bone density. These correlations can inform health interventions and education.
RESUMEN
The current Covid-19 pandemic poses an unprecedented global challenge in the field of education and training. As we have seen, the lack of proper information about the virus and its transmission has forced the general population and healthcare workers to rapidly acquire knowledge and learn new practices. Clearly, a well-informed population is more likely to adopt the correct precautionary measures, thus reducing the transmission of the infection;likewise, properly educated healthcare workers are better equipped to manage the emergency. However, the need to maintain physical distancing has made it impossible to provide in-presence information and training. In this regard, new technologies have proved to be an invaluable resource by facilitating distance learning. Indeed, e-learning offers significant advantages because it does not require the physical presence of learners and teachers. This innovative method applied to serious games has been considered potentially effective in enabling rapid and large-scale dissemination of information and learning through content interactivity. We will review studies that have observed the development and use of serious games to foster information and practices about Covid-19 aimed at promoting behavioral changes in the population and the healthcare personnel involved on the front line.
RESUMEN
BACKGROUND In response to the COVID-19 pandemic, drastic measures for social distancing have been introduced also in Italy, with a substantial impact in delicate conditions like pregnancy and puerperium. The study aimed to investigate the changes in lifestyle, access to health services, and mental wellbeing during the first Italian lockdown in a sample of Italian pregnant women and new mothers. METHODS We carried out a web-based survey to evaluate how pregnant women and new mothers were coping with the lockdown. We collected data about healthy habits (physical exercise and dietary habits), access to health services (care access, delivery and obstetric care, neonatal care, and breastfeeding), and mental wellbeing (psychological wellbeing and emotive support). Descriptive analysis was performed for both groups of participants, whereas a Poisson analysis was used to measure the association between some structural variables (age, education, socio-economic data, partner support, contact, free time, previous children, and pregnancy trimester) and anxiety or depression, difficulties in healthy eating and reduction in physical activity after lockdown started. Chi2 and Adjusted Prevalence Ratios were estimated only for pregnant women. RESULTS We included 739 respondents (response rate 85.8 %), 600 were pregnant (81.2 %), and 139 (18.8 %) had delivered during lockdown (new mothers). We found a high score for anxiety and depression in 62.8 % of pregnant women and 61.9 % of new mothers. During the lockdown, 61.8 % of pregnant women reduced their physical exercise, and 44.3 % reported eating in a healthier way. 94.0 % of new mothers reported to have breastfed their babies during the hospital stay. Regarding the perceived impact of restrictive measures on breastfeeding, no impact was reported by 56.1 % of new mothers, whereas a negative one by 36.7 %. CONCLUSIONS The high prevalence of anxiety and depressive symptoms in pregnant women and new mothers should be a public health issue. Clinicians might also recommend and encourage 'home' physical exercise. On the other hand, about half of the sample improved their approach towards healthy eating and a very high breastfeeding rate was reported soon after birth: these data are an interesting starting point to develop new strategies for public health.
