“…Cortisol levels increase in wintertime. 56 , 57 In this study both mean and average cortisol levels were bit higher in October than in May and August, but the difference was not significant. The activity of sympathetic nervous system is higher in winter, and consequently eg heart rate and blood pressure are higher in winter.…”

Purpose To assess methodology and its limitations for measuring effects of nature-based intervention (NBI). Patients and Methods Participants were 11 middle-aged female health care workers with lowered capacity to work. NBI included six group appointments in six months study period. Heart rate variability (HRV) and self-reported pain and work exhaustion were measured pre-post study period. Salivary α-amylase samples were collected immediately before and after three individual interventions. Salivary cortisol samples were collected on the same three interventions, on three consecutive days starting from the day of intervention, to assess (a) month effect (pre-post study period) and (b) day effect (intervention day vs non-intervention day). Results Individual interventions resulted in increase in α-amylase activity. However, the average fold increase decreased from the 3.05 ± 1.20 of the first intervention to 1.91 ± 1.00 and 1.46 ± 0.77 in the second and third intervention, respectively (p < 0.001). Cortisol concentrations were lower on intervention days vs non-intervention days, the difference being indicative (p = 0.050). Pain and work exhaustion decreased during the study period, as well as HRV, although any of these changes was not statistically significant. Conclusion For a large-scale study, it would be ideal to select assays for both major pathways: hypothalamic-pituitary-adrenal axis can be measured by cortisol, whereas response via autonomic nervous system can be measured by HRV, when roles of sympathetic and parasympathetic nervous systems can be pinpointed separately. Salivary α-amylase can be used when continuous monitoring is not possible. Psychological well-being of participants should be surveyed, as well as their activities and moods on sampling days recorded.

“…(26) A medição dos níveis de cortisol na saliva está ganhando cada vez mais ampla aceitação como método diagnóstico porque eles correspondem apenas a fração bioativa do hormônio, podendo serem avaliados sob várias condições cognitivas e na presença de estresse e ansiedade. (27) Assim, a Terapia Floral, enquanto processo facilitador do autodesenvolvimento do ser humano, gera frequentemente a sensação de relaxamento ou de liberação do excesso de energia disfuncional com consequente redução do estresse. (6) A paz interior e a capacidade de solucionar seus próprios problemas torna as pessoas protagonistas de suas histórias ao utilizar as essências florais.…”

Conflitos de interesse: nada a declarar.Resumo Objetivo: Avaliar o efeito da Terapia floral na evolução do trabalho de parto e na tríade dor-ansiedade-estresse das mulheres durante o nascimento.Métodos: Estudo quase-experimental realizado no período de maio a julho de 2018 no centro-obstétrico de um hospital referência para a assistência ao nascimento de baixo risco na Região Sul do Brasil, com 60 participantes (30 no Grupo Controle e 30 no Grupo Floral). A intervenção consistiu na administração dos Florais de Bach durante o trabalho de parto combinados por compostos capazes de regatar o equilíbrio emocional em situações de dor, ansiedade e estresse com a adição de 99,75% de conhaque orgânico Francês à 30% para 0,25% da tintura mãe. O grupo placebo recebeu uma mistura combinada de água com adição de 99,75% de conhaque orgânico Francês à 30% para 0,25% da tintura mãe. Ambos foram acondicionados em frascos conta gotas de 30 ml de igual tamanho, formato e característica. Para análise foi utilizado o teste t a fim de comparar as variáveis estudadas antes e após a intervenção e entre os grupos.Resultados: As variáveis analisadas como dilatação cervical, contrações uterinas, ocitocina, cortisol e tempo do trabalho de parto apresentaram diferenças significativas para o Grupo Floral quando comparado com o placebo.Conclusão: A Terapia floral pode ser uma alternativa para a mulher durante o trabalho de parto por auxiliar na progressão do parto sem trazer prejuízos ao recém-nascido.

“…Based on prior reports of seasonal variation in telomere length (Beaulieu et al., 2017; Rehkopf et al., 2014; Tennyson et al., 2018), the date of salivary DNA collection was used to create an indicator of season. Northern Meteorological Seasons (e.g., Garay et al., 2019) were used to define winter as December through February, spring as March through May, summer as June through August, and fall as September through November, with season collapsed into autumn/winter and spring/summer for analytic purposes.…”

Telomere length (TL) is proposed to play a mechanistic role in how the exposome affects health outcomes. Little is known about TL during adolescence, a developmental period during which precursors of adult‐onset health problems often emerge. We examined health and demographic sources of variation in TL in 899 youth aged 11–17. Demographic and health information included age, sex, race, household income, caregiver age and marital status, youth tobacco exposure, body mass index, pubertal status, health problems, medication use, and season of data collection. Genomic DNA was extracted from saliva, and T/S ratios were computed following qPCR. Age, race, season of data collection, and household income were associated with the telomere to single copy (T/S) ratio. We found that T/S ratios were larger at younger ages, among Black youth, for saliva collected during autumn and winter, and among households with higher income. Analyses stratified by race revealed that the association between age and T/S ratio was present for Black youth, that season of collection was present across races, but that family demographic associations with T/S ratio varied by race. The results provide information for future telomere research and highlight adolescence as a potentially important developmental phase for racial disparities in telomere shortening and health.
