[Condom use among young Chileans: The role of social determinants, gender roles and mental health].
Despite various strategies implemented to promote sexual education and prevent sexually transmitted infections (STIs), the 10th National Youth Survey revealed that slightly more than half of young people in Chile used a condom during their last sexual encounter. While several sociodemographic, cultural, and psychological predictors have been described, recent studies specific to Chile are scarce. ⋯ Individual characteristics can explain adherence to preventive behaviors and may reflect underlying psychological and cultural factors. Identifying socio-structural, cultural, and psychological factors associated with preventive and protective sexual behaviors should be a health priority, as it enables the design and promotion of more effective social communication campaigns.

The Nobel Prize originated in 1895 when Alfred Nobel signed his will, leaving a large part of his wealth to the creation of the Nobel Foundation and the establishment of this prize, with the vision that people could help improve humanity through knowledge, science, and humanism. The Nobel Prize has been awarded in areas such as physics, physiology or medicine, chemistry, literature, peace, and economics. 943 people and 25 organizations have been awarded since 1901 to this day. The history and knowledge commemorated in the Nobel Prize have allowed an integral development in the understanding, diagnosis, therapy, and scientific progress in different types of cancer, laying the foundations and being the inspiration for thousands of scientists worldwide who work hard in the area of oncology. GLOBOCAN estimates indicated that there were approximately 19 million new cancer cases globally and almost 10 million cancer deaths in 2020 alone; hence, this study reviews and brings together the main scientific discoveries awarded with the Nobel Prize in the area of physiology or medicine and chemistry, which contributed to the knowledge, diagnosis and/or treatment of cancer from 1901 to 2021.

[Cognitive Impairment Among Older Adults in Chile: Evidence from the National Health Survey (ENS 2016-2017)].
Analysis of cognitive impairment in the elderly by age, sex and self-perception of memory using the National Health Survey (ENS 2016-2017). ⋯ A significant percentage of older adults reported a fair to poor (self-perceived) memory. Age was the most significant variable in relation to the suspicion of CD. In other words, the older the age, the greater the cognitive deterioration without significant differences by sex. However, women presented less cognitive impairment.

[Temporality and factors associated with the development of a cerebral infarction in patients with cervical artery dissection].
Cervical artery dissections (CAD) are the leading cause of ischemic stroke (CVA) in young people. The risk factors for stroke and the temporal relationship with CAD are not well characterized. Nor do we have a clinical-radiological classification that allows knowing the risk of stroke. ⋯ Stroke associated with CAD has a relatively low frequency. It is not related to the type of dissected artery. It mainly occurs not simultaneously with CAD and within the first week. The main associated factor for developing a stroke is arterial occlusion (Borgess type IB).1,8-9,3), male sex (p < 0.001; OR: 0.2; CI: 0.06-0.8) and oral contraceptives (p = 0.02; OR: 0.2; CI: 0.06-0.8).
