From the first months of 2020, the COVID-19 pandemic led most governments to implement social distancing measures that harmed the mental health of sensitive persons. Several studies have shown changes in the prevalence of mental health conditions in a wide range of ages. However, the impact described in the scientific literature show that age and sociocultural factors might affect outcomes. Objective: Comparing anxiety and depression levels, as well as substance abuse prevalence in Mexican college students before and during the COVID-19 pandemic. Method: Application of the Beck Anxiety Inventory, Beck Depression Inventory, and Substance Abuse Screening Test. Method: The study compared data from three college student samples: three obtained before the pandemic (n = 1,709) and one during the pandemic (n = 180). Results: Anxiety and depression levels during the pandemic were higher than before the pandemic. Discussion: There were no differences in the abuse of substances risk prevalence. These findings characterize changes in Mexican college students, showing that, despite differences among countries regarding pandemic policies, changes in mental health consistently revealed similar patterns.

Aim. Determine the clinical-epidemiological characteristics of patients with ulcers in the lower extremities, which leads to adequate initial orientation of their etiology and management in primary health care, as it is a frequent pathology and with great economic, social, and environmental impact. general condition of the patient. Methodology. A descriptive, crosssectional study was carried out, which included 30 patients, evaluating various clinical and epidemiological variables statistically analyzed and the results presented in graphs and tables. Results. 60% were female and 40% male, the average age was 63.33 years; 36.66% had previous ulcers. In 60% the etiology of the ulcer was venous and in 23.33% it was neuropathic; 43.33% had grade I ulcers, and 36.67% had grade II ulcers. The most frequent comorbidities were arterial hypertension, venous insufficiency, and diabetes mellitus. The correct initial etiological diagnosis based on the anamnesis and clinical assessment is crucial to install the appropriate treatment measures and avoid chronicity and recurrence of the ulcer.

The influence of cultural and family variables is relevant for the development of food preferences and habits, especially during school age. In Chile, the prevalence of childhood obesity and overweight reaches 44.5%. Objective: to compare beliefs about obesity and children's nutrition among caregivers of Mapuche and non-Mapuche children. Materials and method: a phenomenographic qualitative study, in which semi-structured interviews were used as the data collection instrument, involving 26 primary caregivers of first to fourth grade students from two municipalities in centralsouthern Chile. Results: similarities were found in the core knowledge and beliefs about obesity and nutrition between Mapuche and non-Mapuche groups. However, there are particularities in the experience of secondary elements, such as the belief among the Mapuche group that children need more food than what is provided at schools, or the perception of having greater access to processed foods.

Educational communities have the potential to project themselves as transforming niches of living conditions around the identification of health needs and the search for alternatives to solve them. Within the framework of the Master's in Public Health at the Universidad de La Sabana, progress has been made in strategies to generate this link, through support in the formulation of a community health program in an educational environment, based on the adaptation of the model Precede- Procede, a method to plan, conduct and evaluate health education interventions. Taking into account the above, the objective of this article is to reflect on the contributions of the model for the formulation of community health programs in educational settings, regarding primary health care and the policies of healthy educational settings, considering that they are referents regulations in the Colombian territory. In summary, this model is considered a favorable option for the formulation of health programs in the educational context because it privileges community participation, addresses contextualized problems and gives the possibility for students to integrate from an early age and educational communities to become social managers of their own health.

Living donor liver transplantation is a complex and challenging procedure. The surgeon needs to guarantee maximum safety for the donor, as well as the best quality of the graft for the recipient. For this reason, the implementation of mini-invasive surgery has been slow in this area. However, in the last 10 years, due to the advances in laparoscopic liver surgery, the interest of some highly specialized groups has increased in incorporating mini-invasive surgery into donor surgery, mainly in pediatric living donor liver transplantation. The favorable results obtained in this field, have even led to turn this procedure, into the technique of choice for pediatric living donor liver transplantation. Nevertheless, this procedure is even more challenging for adult-to-adult living donor transplantation. To meet the volumetric criteria of an adult, a complete hepatectomy of right or left lobe is mostly required. This surgery is of greater complexity and risk for the donor, so its indication by minimally invasive approach is limited to high-volume centers with preparation, both in laparoscopy and liver transplants. In this report we seek to present our surgical technique and initial experience with the first pure laparoscopic right hepatectomy for adult-to-adult living donor liver transplantation carried out in Chile.

Objective. Reconstruct the experience of the Virtual Campus for Public Health (VCPH) from 2012 to 2019 in Colombia. Methods. The experience of public health training through the VCPH in Colombia in the period 2012-2019 was systematized. The information is presented in cross-section time series to show the evolution of the VCPH in Colombia over time. Results. A total of 2 627 health professionals took tutored courses and 34 012 followed self-learning courses on relevant, up-to-date, priority public health issues. An important aspect was the opportunity to access remote regions through VCPH training processes that were cost-free for end users. The experience highlights the relevance of the VCPH in reducing the gap in updated human talent in the health field through virtual education with diversity in its modalities and content. Conclusions. Reconstruction of the experience in Colombia showed how the VCPH evolved and strengthened to offer quality training processes that respond to the country's problems and needs. Collaborative work between universities and the Pan American Health Organization resulted in consolidation of the VCPH. [ABSTRACT FROM AUTHOR]

In classical viral infections, the avidity of immunoglobulin G (IgG) is low during acute infection and high a few months later. As recently reported, SARS-CoV-2 infections are not following this scheme, but they are rather characterized by incomplete avidity maturation. This study was performed to clarify whether infection with seasonal coronaviruses also leads to incomplete avidity maturation. The avidity of IgG toward the nucleoprotein (NP) of the seasonal coronaviruses 229E, NL63, OC43, HKU1 and of SARS-CoV-2 was determined in the sera from 88 healthy, SARS-CoV-2-negative subjects and in the sera from 70 COVID-19 outpatients, using the recomLine SARS-CoV-2 assay with recombinant antigens. In the sera from SARS-CoV-2-negative subjects, incomplete avidity maturation (persistent low and intermediate avidity indices) was the lowest for infections with the alphacoronaviruses 229E (33.3%) and NL63 (61.3%), and the highest for the betacoronaviruses OC43 (77.5%) and HKU1 (71.4%). In the sera from COVID-19 patients, the degree of incomplete avidity maturation of IgG toward NP of 223E, OC43, and HKU1 was not significantly different from that found in SARS-CoV-2- negative subjects, but a significant increase in avidity was observed for IgG toward NP of NL63. Though there was no cross-reaction between SARS-CoV-2 and seasonal coronaviruses, higher concentrations of IgG directed toward seasonal coronaviruses seemed to indirectly increase avidity maturation of IgG directed toward SARS-CoV-2. Our data show that incomplete IgG avidity maturation represents a characteristic consequence of coronavirus infections. This raises problems for the serological differentiation between acute and past infections and may be important for the biology of coronaviruses. [ABSTRACT FROM AUTHOR]
