Kinetics of humoral immune response over 17 months of COVID-19 pandemic in a large cohort of healthcare workers in Spain: the ProHEpiC-19 study.

Background: Understanding the immune response to the SARS-CoV-2 virus is critical for efficient monitoring and control strategies. The ProHEpic-19 cohort provides a fine-grained description of the kinetics of antibodies after SARS-CoV-2 infection with an exceptional resolution over 17 months.

Methods: We established a cohort of 769 healthcare workers including healthy and infected with SARS-CoV-2 in northern Barcelona to determine the kinetics of the IgM against the nucleocapsid (N) and the IgG against the N and spike (S) of SARS-CoV-2 in infected healthcare workers.

Designing a Person-Centred Integrated Care Programme for People with Complex Chronic Conditions: A Case Study from Catalonia.

Introduction: The prevalence of people with complex chronic conditions is increasing. This population's high social and health needs require person-centred integrated approaches to care.

Methods: To collect data about experiences with the health system and identify priorities for care, we conducted 2 focus groups and 15 semi-structured interviews involving patients with multimorbidity and advanced conditions, caregivers, and representatives of patients' associations.

A Cost-Benefit Analysis of the COVID-19 Asymptomatic Mass Testing Strategy in the North Metropolitan Area of Barcelona.

Background: The epidemiological situation generated by COVID-19 has highlighted the importance of applying non-pharmacological measures in the management of the epidemic. Mass screening of the asymptomatic general population has been established as a priority strategy by carrying out diagnostic tests to detect possible cases, isolate contacts, cut transmission chains and thus limit the spread of the virus.

Objective: To evaluate the economic impact of mass COVID-19 screenings of an asymptomatic population during the first and second wave of the epidemic in Catalonia, Spain.

[Impact of the eConsultation on the primary care agenda].

Objective: A «before and after» type observational study was carried out to assess the impact of the virtual consultation (eConsulta) on the frequency with which the patient visits their primary care center once they have had their first virtual consultation.

Setting: Assigned population of the primary care center of Masnou-Alella and Ocata-Teià, Catalan Health Institute.

Participants: A random sampling was performed and 329 patients who engaged in eConsulta were compared with 329 statistically similar patients in age, sex and medical complexity who did not engage in eConsulta.

[Infectious Disease Prevention Group. Update on vaccines, 2020].

Vaccine development is one of the fastest growing sectors in medicine now and in the future, as we are living with the emergency health care for the SARS-CoV-2 coronavirus. The semFYC PAPPS program biannually publishes the recommendations of the group and, in this edition, special emphasis is placed on the common vaccination proposed by the Ministry of Health, where, at last, it no longer discriminates between paediatrics and adults, and proposes a calendar throughout life. The main novelties in the field of vaccinology today are focused on the consolidation of the nonavalent vaccine against the human papilloma virus and in the change of the dose of monovalent meningitis vaccine C for the tetravalent one, ACWY, at age 12.

[Descriptive study of the health service workers of a Primary Care Department confined by Covid-19.].

Objective: The Covid-19 pandemic is testing the resistance of health systems, the preservation of health professionals is a priority in processes of this type. The professionals' exposure to suspicious contacts often requires their confinement. The objective was to know the epidemiological characteristics of the primary care professionals who required confinement.

[Management of odontogenic infections in Primary Care: Antibiotic?].

Our aim is to contribute to the rational use of antibiotics prescribed by family doctors when a patient consults for a dental problem. Nowadays we should not ask which antibiotic to give. The question has to be if we need to prescribe antibiotics in front of the most common odontogenic infections seen in our practice.

Extended screening of Trypanosoma cruzi among the offspring of infected women. Barcelona North metropolitan area, Catalonia (Spain), 2005-2016.

Introduction: To date, very little data is available on the extensive, familiar, serological screening of Trypanosoma cruzi from infected-index cases. As it is a parasite with possibility of mother-to-child fetal transmission, the study of the offspring of chronically infected women has a special relevance.

Methods: An observational study using a capture-recapture method that evaluates the offspring serological status of women diagnosed with T.

[I'm going to the dentist: antibiotic as a prevention or as a treatment?].

Odontogenic infections account for 10% of all antibiotic prescriptions in Spain. Despite the frequency and importance of these infections, there is often confusion between prophylaxis and treatment. The oral cavity is a complex ecosystem made up of over 500 bacterial species.
