“…A study in Australia found a 23% increased risk of death from heart failure in winter. Because winter in Australia is mild, this finding strongly implicates lower serum 25(OH)D levels rather than low winter temperatures [450].…”

“…Evidence exists that the seasonality of CVD is linked to solar UVB [447]. However, the effect of colder temperatures in winter cannot be completely ruled out as an explanation for the observed seasonality [448,449], although probably not as important as vitamin D, on the basis of findings regarding seasonality of CVD deaths in warm countries such as Australia [450].…”

The Sun has played a major role in the development of life on Earth. In Western culture, people are warned against Sun exposure because of its adverse effects: erythema, photoimmunosuppression, photoageing, photocarcinogenesis, cataracts and photokeratitis. However, Sun exposure is also beneficial, since moderate doses give beneficial physiological effects: vitamin D synthesis, reduction of blood pressure and mental health. Shortage of Sun exposure may be even more dangerous to human health than excessive exposure. Avoiding Sun exposure leads to vitamin D deficiency which is associated not only with rickets and osteomalacia, but also with increased risk of cardiovascular disease, multiple sclerosis, rheumatoid arthritis, diabetes, influenza, many types of cancer and adverse pregnancy outcomes. Solar radiation induces nitric oxide release in tissue and immediate pigment darkening which certainly play important roles, although these are still unknown. Action spectra relevant for health are described. We will also review what is known about spectral and intensity variations of terrestrial solar radiation as well as its penetration through the atmosphere and into human skin and tissue.

“…Estudo com dados da Austrália avaliou a variação sazonal na mortalidade para sete grupos de doenças cardiovasculares. O maior aumento durante o inverno ocorreu para o grupo de insuficiência cardíaca (Barnett et al, 2008). O mesmo padrão com maior incidência de mortes por insuficiência cardíaca no inverno foi relatada na Argentina (Diaz et al, 2007).…”

“…Uma meta-análise avaliou o excesso de mortalidade cardiovascular nas segundas-feiras, o resultado foi uma odds ratio de 1,19 (IC 95%: 1,17-1,21) sendo um pouco maior para o sexo masculino (Witte et al, 2005). Outra meta-análise avaliou o excesso de morbidade de eventos cardiovasculares, confirmou um pequeno excesso nas segundas-feiras (Barnett et al, 2008).

IMPORTANCE Clinical guidelines for the early management of acute heart failure in the emergency department (ED) setting are based on only moderate levels of evidence, with subsequent low adherence to these guidelines.OBJECTIVE To test the effect of an early guideline-recommended care bundle on short-term prognosis in older patients with acute heart failure in the ED. DESIGN, SETTING, AND PARTICIPANTSStepped-wedge cluster randomized trial in 15 EDs in France of 503 patients 75 years and older with a diagnosis of acute heart failure in the ED from December 2018 to September 2019 and followed up for 30 days until October 2019.INTERVENTIONS A care bundle that included early intravenous nitrate boluses; management of precipitating factors, such as acute coronary syndrome, infection, or atrial fibrillation; and moderate dose of intravenous diuretics (n = 200). In the control group, patient care was left to the discretion of the treating emergency physician (n = 303). Each center was randomized to the order in which they switched to the "intervention period." After the initial 4-week control period for all centers, 1 center entered in the intervention period every 2 weeks. MAIN OUTCOMES AND MEASURESThe primary end point was the number of days alive and out of hospital at 30 days. Secondary outcomes included 30-day all-cause mortality, 30-day cardiovascular mortality, unscheduled readmission, length of hospital stay, and kidney impairment.RESULTS Among 503 patients who were randomized (median age, 87 years; 298 [59%] women), 502 were analyzed. In the intervention group, patients received a median (interquartile range) of 27.0 (9-54) mg of intravenous nitrates in the first 4 hours vs 4.0 (2.0-6.0) mg in the control group (adjusted difference, 23.8 [95% CI, 13.5-34.1]). There was a significantly higher percentage of patients in the intervention group treated for their precipitating factors than in the control group (58.8% vs 31.9%; adjusted difference, 31.1% [95% CI, 14.3%-47.9%]). There was no statistically significant difference in the primary end point of the number of days alive and out of hospital at 30 days (median [interquartile range], 19 [0-24] d in both groups; adjusted difference, −1.9 [95% CI, −6.6 to 2.8]; adjusted ratio, 0.88 [95% CI, 0.64-1.21]). At 30 days, there was no significant difference between the intervention and control groups in mortality (8.0% vs 9.7%; adjusted difference, 4.1% [95% CI, −17.2% to 25.3%]), cardiovascular mortality (5.0% vs 7.4%; adjusted difference, 2.1% [95% CI, −15.5% to 19.8%]), unscheduled readmission (14.3% vs 15.7%; adjusted difference, −1.3% [95% CI, −26.3% to 23.7%]), median length of hospital stay (8 d in both groups; adjusted difference, 2.5 [95% CI, −0.9 to 5.8]), and kidney impairment (1% in both groups).CONCLUSIONS AND RELEVANCE Among older patients with acute heart failure, use of a guideline-based comprehensive care bundle in the ED compared with usual care did not result in a statistically significant difference in the number of days alive and out of the hospital a...
