“…The risk of sudden infant death syndrome in premature infants is three times higher than that of full-term infants [36]. However, the risk factors for sudden infant death syndrome in premature infants are strongly associated with maternal age, tobacco use, meteorological factors, and genetics but not AOP [22, 28, 48, 90]. …”

Apnea of prematurity: from cause to treatment

Apnea of prematurity (AOP) is a common problem affecting premature infants, likely secondary to a “physiologic” immaturity of respiratory control that may be exacerbated by neonatal disease. These include altered ventilatory responses to hypoxia, hypercapnia, and altered sleep states, while the roles of gastroesophageal reflux and anemia remain controversial. Standard clinical management of the obstructive subtype of AOP includes prone positioning and continuous positive or nasal intermittent positive pressure ventilation to prevent pharyngeal collapse and alveolar atelectasis, while methylxanthine therapy is a mainstay of treatment of central apnea by stimulating the central nervous system and respiratory muscle function. Other therapies, including kangaroo care, red blood cell transfusions, and CO2 inhalation, require further study. The physiology and pathophysiology behind AOP are discussed, including the laryngeal chemoreflex and sensitivity to inhibitory neurotransmitters, as are the mechanisms by which different therapies may work and the potential long-term neurodevelopmental consequences of AOP and its treatment.

“…Точка росы, показатель одновременно отражающий влажность воздуха и температуру, при которой происхо-дит насыщение воздуха парами воды, свидетельствует о том, что употребление алкоголя создает для организма ме-нее устойчивые условия к охлаждению. Исследования, проведенные в других странах, указы-вают на связь количества случаев ВСС с сочетанием хо-лодной и влажной погоды с низким атмосферным давле-нием [13], среднемесячной температурой и возникнове-нием сердечного приступа (r=-0,404) [14], холодной и сухой погодой [15]. Даже в условиях круглогодичных по-ложительных температур (юг Израиля) большее число эпизодов ВСС регистрируется в «холодную погоду» -при температуре ниже 15,4 °С, чем при температуре выше 34,2 °С (р<0,05) [14].…”

“…The mode of death in these studies is not known. Despite the suggestive epidemiologic evidence and a solid physiological basis discussed later in this paper, there is only a handful of studies on the potential association between cold weather and SCD4561011, and no studies on the association between cold spells and SCD9.…”

Sudden cardiac death (SCD) is the leading cause of death. The current paradigm in SCD requires the presence of an abnormal myocardial substrate and an internal or external transient factor that triggers cardiac arrest. Based on prior mechanistic evidence, we hypothesized that an unusually cold weather event (a cold spell) could act as an external factor triggering SCD. We tested potential effect modification of prior diagnoses and select pharmacological agents disrupting pathological pathways between cold exposure and death. The home coordinates of 2572 autopsy-verified cases of ischaemic SCD aged ≥35 in the Province of Oulu, Finland, were linked to 51 years of home-specific weather data. Based on conditional logistic regression, an increased risk of ischaemic SCD associated with a cold spell preceding death (OR 1.49; 95% CI: 1.06–2.09). Cases without a prior diagnosis of ischaemic heart disease seemed more susceptible to the effects of cold spells (OR 1.70; 95% CI: 1.13–2.56) than cases who had been diagnosed during lifetime (OR 1.14; 95% CI: 0.61–2.10). The use of aspirin, β-blockers, and/or nitrates, independently and in combinations decreased the risk of ischaemic SCD during cold spells. The findings open up new lines of research in mitigating the adverse health effects of weather.
