Public health implications. This information could contribute to the design of a multicomponent intervention to improve adherence to colon cancer screening. In order to evaluate adherence to colorectal cancer (CRC) screening among members of the Health Plan of the Hospital Italiano de Buenos Aires in Argentina, we conducted a retrospective cohort study using secondary data from the electronic medical record. We included all members over 50 years of age during the period 2008-2022. We assessed the number and type of screening tests performed and the proportion of members covered for screening. We analyzed 112,112 participants, with a median age of 58.6 years and a follow-up time of 8.6 years. Colonoscopy was the most commonly used test. The maximum coverage reached was 47.1% in December 2022. In conclusion, adherence to CRC screening was suboptimal, as was the method used.

Cystic echinococcosis is a neglected disease associated with contact between dogs, humans and sheep. In countries such as Peru, control programs include vaccination of sheep; however, vaccination in dogs is a late control strategy to eliminate the adult parasite or to avoid infection with eggs in the environment. Main findings. We were able to clone and express a recombinant protein (tropomyosin) of the adult parasite in a bacterial system with immunogenic properties. Implications. Obtaining the tropomyosin recombinant protein from E. granulosus allows the development of vaccine candidates in dogs and the exploration of diagnostic tests in hosts. This study aimed to clone, express and produce the recombinant Echinococcus granulosus tropomyosin isoform A protein (EgTrpA) that maintains its antigenic and immunogenic properties as a potential vaccine candidate for dogs and sheep. The Echinococcus granulosus tropomyosin protein (EgTrp) gene was cloned into two vectors: Tropo/His-tag [pET28a (+)] and Tropo/GST-tag (pGEX6P-1). It was then expressed in E. coli BL21. Protein identity was determined by two-dimensional electrophoresis. Immunogenicity and antigenicity were verified by immunizing rabbits with each recombinant protein and assessed by western blot and ELISA. Two-dimensional electrophoresis identified the recombinant EgTrp protein as isoform A. The recombinant proteins showed recognition reactions on Western Blot and serum from immunized rabbits showed an increase in Tropo/His-tag IgG antibodies similar to Tropo/GST-tag.

Discrimination as a negative social determinant for health entails limitations in several areas, even affecting people's quality of life. Its research is mainly aimed at the racial context. Studies on other types of discrimination are scarce in the scientific literature. Main findings. People with mental disorders perceived discrimination due to different sociodemographic conditions and had lower quality of life scores. Implications. Discrimination as exclusionary behavior is facilitated and becomes more complex in people with some vulnerability. In order to determine the relationship between perceived discrimination and quality of life, we carried out a cross-sectional analytical study of secondary sources. Data from three cities in the Peruvian highlands were analyzed. The sample of 3889 adults was grouped into participants with mental disorders (n=1499) and without mental disorders (n=2390). We used statistical tests of independence and independent group comparison for complex samples. The lowest quality of life was found in the group of participants with mental disorders who perceived themselves discriminated in the last year by sex (p<0.001), age (p<0.001), weight (p<0.001), dress (p<0.001), economic or social status (p<0.001), educational level (p<0.001), religion (p=0.008), friendships (p=0.005) and height (p=0.008).
