AI Article Synopsis
- The study aimed to evaluate the presence of IgG antibodies against the spike (S) and nucleocapsid (N) proteins of SARS-CoV-2 among university students in Southern Mexico.
- A total of 1418 serum samples were analyzed, revealing a seroprevalence of 39.9% for those positive to both S and N proteins, with notable variation based on age, vaccination status, and contact with infected individuals.
- The findings suggest that university students may significantly contribute to the spread of COVID-19, with a higher seroprevalence likely linked to cultural attitudes towards safety measures.
Article Abstract
Background: Natural infection and vaccination against SARS-CoV-2 is associated with the development of immunity against the structural proteins of the virus. Specifically, the two most immunogenic are the S (spike) and N (nucleocapsid) proteins. Seroprevalence studies performed in university students provide information to estimate the number of infected patients (symptomatic or asymptomatic) and generate knowledge about the viral spread, vaccine efficacy, and epidemiological control. Which, the aim of this study was to evaluate IgG antibodies against the S and N proteins of SARS-CoV-2 at university students from Southern Mexico.
Methods: A total of 1418 serum samples were collected from eighteen work centers of the Autonomous University of Guerrero. Antibodies were detected by Indirect ELISA using as antigen peptides derived from the S and N proteins.
Results: We reported a total seroprevalence of 39.9% anti-S/N (positive to both antigens), 14.1% anti-S and 0.5% anti-N. The highest seroprevalence was reported in the work centers from Costa Grande, Acapulco and Centro. Seroprevalence was associated with age, COVID-19, contact with infected patients, and vaccination.
Conclusion: University students could play an essential role in disseminating SARS-CoV-2. We reported a seroprevalence of 54.5% against the S and N proteins, which could be due to the high population rate and cultural resistance to safety measures against COVID-19 in the different regions of the state.

The engagement of senior citizens with urban nature has been shown to provide multiple health benefits and mitigate health issues associated with demographic aging. This review utilized the PRISMA methodology to systematically analyze the relationship between monitoring tools, seniors' behaviors in urban nature, and influencing factors. The main findings are as follows: (1) 4 main types, including self-reports, on-site observations, sensors, and third-party data, and 24 sub-types of measurement tools: ranging from questionnaires to crowdsourced imagery services.

Background: While previous cross-sectional studies have suggested a link between psychotic-like experiences (PLEs) and internet addiction (IA), longitudinal evidence remains scarce. This study aimed to explore the prospective relationship between IA and PLEs among college students.
Method: A total of 636 college students (80 % female) were assessed in November 2022 and again one year later.
Purpose: After recent policy and practice changes, health care schools are expected to involve patients as partners in the management, design, and delivery of professional curricula. However, what these partnerships mean for academic communities and the processes needed to support them are not yet understood. This study examines what involving patients as partners within an academic community means for key stakeholders.
