Incidence and prevalence of headache in influenza: A 2010-2021 surveillance-based study.

Background And Purpose: Influenza is a common cause of acute respiratory infection, with headache being one of the symptoms included in the European Commission case definition. The prevalence of headache as a symptom of influenza remains unknown. We aimed to describe the incidence and prevalence of headache in patients with influenza.

Factors associated to the presence of headache in patients with influenza infection and its consequences: a 2010-2020 surveillance-based study.

Headache is a common symptom of influenza infection; however, its causes and consequences remain uncertain. In this manuscript, we analyzed which demographic and clinical factors were associated with the presence of headache during the course of influenza infection and whether patients with headache had a different prognosis, evaluated by need of hospitalization, sick leave or school absenteeism. The influence study (NCT05704335) was an observational study that analyzed data routinely collected from the Health Sentinel Network between 2010 and 2020.

Comprehensive surveillance of acute respiratory infections during the COVID-19 pandemic: a methodological approach using sentinel networks, Castilla y León, Spain, January 2020 to May 2022.

BackgroundSince 1996, epidemiological surveillance of acute respiratory infections (ARI) in Spain has been limited to seasonal influenza, respiratory syncytial virus (RSV) and potential pandemic viruses The COVID-19 pandemic provides opportunities to adapt existing systems for extended surveillance to capture a broader range of ARI.AimTo describe how the Influenza Sentinel Surveillance System of Castilla y León, Spain was rapidly adapted in 2020 to comprehensive sentinel surveillance for ARI, including influenza and COVID-19.MethodsUsing principles and methods of the health sentinel network, we integrated electronic medical record data from 68 basic surveillance units, covering 2.

Influenza surveillance: determining the epidemic threshold for influenza by using the Moving Epidemic Method (MEM), Montenegro, 2010/11 to 2017/18 influenza seasons.

Background: In 2009, an improved influenza surveillance system was implemented and weekly reporting to the World Health Organization on influenza-like illness (ILI) began. The goals of the surveillance system are to monitor and analyse the intensity of influenza activity, to provide timely information about circulating strains and to help in establishing preventive and control measures. In addition, the system is useful for comparative analysis of influenza data from Montenegro with other countries.

Prevalence of overweight and obesity in child population. A study of a cohort in Castile and Leon, Spain.

Introduction: Several studies warn that overweight and obesity have become an epidemic with severe consequences in the population's health. The objetive of the present study is to estimate the prevalence of overweight and obesity in Castile and Leon in a sample of children at 6, 11 and 14 years of age, to describe its evolution and its association with life habits and antecedents.

Material And Methods: Observational study, retrospective cohort, performed by the pediatricians of the Health Sentinel Network.

[Prevalence and clinical characteristics of subclinical hypothyroidism in an opportunistic sample in the population of Castile-León (Spain)].

Objective: To describe the distribution of thyroid-stimulating hormone (TSH) values and to estimate the prevalence of subclinical hypothyroidism in the adult population of Castile and León (Spain).

Method: An observational study was conducted in an opportunistic sample of 45 primary care centers in Castile and León. TSH was determined in people aged ≥35 years that attended a primary care physician and had a blood test for any reason.

Actual and preferred place of death of home-dwelling patients in four European countries: making sense of quality indicators.

Background: Dying at home and dying at the preferred place of death are advocated to be desirable outcomes of palliative care. More insight is needed in their usefulness as quality indicators. Our objective is to describe whether "the percentage of patients dying at home" and "the percentage of patients who died in their place of preference" are feasible and informative quality indicators.

Hospitalizations of cancer patients in the last month of life: quality indicator scores reveal large variation between four European countries in a mortality follow-back study.

Background: Repeated and long hospitalizations of cancer patients at the end of life have been suggested as indicators of low quality of palliative care. Comparing the care delivered between different countries with the help of these quality indicators may identify opportunities to improve practice. Our objective is twofold: firstly, to describe the scores for the existing quality indicators "the percentage of time spent in hospital" and "the proportion of adult patients with more than one hospitalization in the last 30 days of life" in populations of cancer patients in four European countries and to see whether these countries met previously defined performance standards; secondly, to assess whether these scores are related to receiving palliative care from their GP.

[Epidemiological characteristics and types of domestic and leisure accidents: sentinel health network of Castilla y León (2009)].

Objectives: To study incidence, epidemiological characteristics and types of domestic and leisure accidents in Castilla y León during 2009.

Design: A descriptive study using a prospective sample design.

Emplacement: Health Primary Care Centres of Castilla y León.

[Guide to the principles and methods of health sentinel networks in Spain].

Health sentinel networks are being increasingly used in the study of health-related problems. The present article aims to provide a methodological guide - designed by regional sentinel network managers and based on the results of a Delphi study - that can be used to set up and develop a health sentinel network. The main topics in the guide are the following: definition of a health sentinel network; network description: aims and structure; methods for the selection of sentinel participants; description of health processes suitable for study through this methodology: incidence, case definition, exclusion and inclusion criteria; description of the target population: the denominator for incidence rates estimates; quality indicators; periodicity of data collection; dissemination of the information: periodicity and methods, and incorporation of the participants in the decision-making process through multidisciplinary commissions.

[Design of a population-based study of cardiovascular risk in Castile and Leon [Spain] through primary care teams].

We describe the design and the response indicators in a cross sectional study to estimate several factors associated with cardiovascular risk in the population of Castile and Leon. A sample of 4,950 individuals aged 15 years and above was obtained in two stages: in the first stage, 198 primary care physicians were selected and in the second stage a sample of 25 persons from each primary care physician's list was obtained. The response rate was 98% among primary care physicians and 80% among the population.

[Health sentinel networks in Spain. Consensus for a guide of principles and methods].

Since the eighties, health sentinel networks have been active in our country, but with a variety of objectives, methods and different development levels in the autonomous communities. The necessity of standardising the management and harmonising the indicators has concluded in a research project on the Spanish health sentinel networks, one of whose objectives is to establish a guide for work principles and methods. A panel of 23 experts has made a study using the Delphi method to agree, in three consecutive phases, a definition of sentinel network, the objectives and the management principles and other aspects related to the organisation and functioning.

Eating disorders. Prevalence and risk profile among secondary school students.

Background: Eating disorders (EDs) are an important public health problem in developed countries. Despite the amount of epidemiological studies and causal theories, there is a great disparity of estimates and many questions remain still unclear. The aim of this study was to estimate the prevalence of the population at risk of developing EDs and describe the risk profiles among adolescents and young people.
