Sex-related cardiovascular arrest is a rare event occurring typically among middle-aged men with cardiovascular risk.[1,2]The main etiologies of sex-related sudden cardiovascular arrest are acute coronary syndrome and subarachnoid hemorrhage and,to a lesser extent,chronic coronary artery disease and structural non-ischemic heart disease.[3]Coital angina that occurs during the minutes or hours after sexual activity represents<5%of all anginal attacks and it is rare in patients who do not have angina during strenous physical exertion.[4]Moreover,sexual activity is the cause of<1%of all acute myocardial infarctions.[5]Sudden death during sexual intercourse is reported with an incidence of 0.6%–1.7%.[6–8]The investigation of sudden death related to sexual activity may be difficult as it may be regarded as shameful or disgraceful to the family members and,especially to the remaining *** of rarity of epidemiological data,considerable bias in the investigation of sudden death related to sexual activity has to be expected.[9–11]Extramarital sexual activity with younger partner and unfamiliar setting seems to represent risk factor as well as excessive food and alcohol consumption.[7]

Old-growth forests play a key-role in reducing atmospheric carbon dioxide(CO_(2)) concentrations by storing large CO_(2)amounts in biomass and soil over *** quantifies the carbon pool into different forest compartments in three Mediterranean old-growth forests of Southern Italy populated by Pinus laricio,Fagus sylvatica and Abies *** carbon pools have been assessed per compartment,i.e.,living trees,dead wood,litterfall(foliar and woody),roots and 0-20 cm topsoil,combining the whole old-growth forest mass,(i.e.,using tree allometric relationships,deadwood factor conversions,root-to-shoot ratios,litterfall and soil samplings) by the respective organic carbon *** results show the considerable capacity of these forest ecosystems in storing CO_(2)in biomass and soil,with carbon pool values ranging from 532.2to 596.5 Mg C *** trees and 0-20 cm topsoil had larger carbon pool,contributing 53.0 and 22.1%,*** most cases,organic carbon concentration was higher(more than 60%) than the average carbon conversion rate of 50%,especially in living trees,deadwood,and woody *** study contributes further scientific evidence of the capacity of old-growth forests in storing CO_(2)in their different compartments,with special evidence on tree biomass,litterfall and mineral soil,thereby highlighting the key role of old-growth forests within the challenge of climate change mitigation.
