Risky behaviours and injuries amongst Catalan children with ADHD: does pharmacological treatment improve outcomes?

Background: Attention-Deficit/Hyperactivity Disorder (ADHD) prevalence rates are around 5-10% of school-aged children. We test whether medication use for ADHD decreases the likelihood of risky behaviour (sexual behaviour, alcohol, tobacco, and drug consumption) and injuries amongst children aged 6-18.

Methods: We use a large administrative dataset for the whole population of Catalan children in Spain who were born between 1998 and 2012.

Effects of a nutrition education intervention on food-provision managerial decisions in Catalan old age nursing homes.

Introduction: Existing research does not provide definitive conclusions on the most effective initiatives for preventing malnutrition among older adult residents in nursing homes.

Objective: We aimed to assess whether a nutrition education intervention provided to nursing home managers can improve dietary managerial decisions within nursing homes.

Methods: We performed a multicenter study, where each center was randomized to an intervention or a control group.

The influenza vaccination's impact elderly's health outcomes in Catalonia (Spain).

A multimodal group-based immersive virtual reality intervention for improving cognition and mental health in patients with post-covid-19 condition. A quasi-experimental design study.

Introduction: Adults with Post-COVID-19 Condition (PCC) may show cognitive impairments in attention, processing speed, memory, and executive function. Multimodal programs that combine cognitive training, physical activity and emotional tasks, such as mindfulness-based interventions (MBIs), may offer a suitable alternative for improving PCC treatments. Immersive Virtual Reality (IVR) is a promising technology that can enhance traditional cognitive training, physical activity, and MBIs.

Primary care team reorganisation after the SARS-COV-2 pandemic. Differences between Catalonia and Spain in the PRICOV study.

Background: Spanish primary care services are managed differently by each region's authorities. Catalonia started its services provision and design nearly two decades before other Spanish regions and developed nurses' roles and task shifting in primary care.

Purpose: This work identifies differences in the Europe PRICOV-19 study answers between Catalonia and those submitted from the rest of Spain regarding how primary care teams (PCT) were organised during the SARS-CoV-2-2019 pandemic, how tasks and roles changed, and the pandemic's impact on the care providers.

Prevalence and coexistence of type 2 inflammatory diseases.

Background: Type 2 inflammation has been described as a pathophysiological basis common to some diseases, such as atopic dermatitis (AD), chronic rhinosinusitis with nasal polyps, and asthma (CRSwNP).

Objective: The present study used population-based prevalence in Catalonia to analyse the coexistence of type 2 inflammatory diseases in patients primarily diagnosed with the above mentioned conditions.

Results: We found a high degree of coexistence of type 2 inflammatory diseases among these patients, with the prevalence being higher in the severe forms, except for AD.

Identifying non-adult attention-deficit/hyperactivity disorder individuals using a stacked machine learning algorithm using administrative data population registers in a universal healthcare system.

Background: This research project aims to build a Machine Learning algorithm (ML) to predict first-time ADHD diagnosis, given that it is the most frequent mental disorder for the non-adult population.

Methods: We used a stacked model combining 4 ML approaches to predict the presence of ADHD. The dataset contains data from population health care administrative registers in Catalonia comprising 1,225,406 non-adult individuals for 2013-2017, linked to socioeconomic characteristics and dispensed drug consumption.

The contribution of risk perception and social norms to reported preventive behaviour against selected vector-borne diseases in Guyana.

Preventing vector-borne diseases (VBDs) mainly relies on effective vector control tools and strategies, which in turn depend on population acceptance and adherence. Inspired by the abundant recent literature on SARS-COV-2, we investigate the relationship between risk perception and preventive behaviour for selected VBDs and the extent to which risk perception is determined by social norms. We use cross-sectional data collected from 497 individuals in four regions of Guyana in 2017.

How has the strict lockdown during the SARS-COV-2 outbreak changed the diet of Spaniards?

Purpose: We investigate the impact of a specific macroeconomic shock that occurred as a response to the SARS-COV-2 outbreak, namely the strict lockdown imposed in Spain on the March 14, 2020.

Methods: We use fortnightly purchase data relating to over 50,000 households from a supermarket chain in Catalonia from March to June in 2019 and 2020. Using a panel data approach, we analyse the impact of the lockdown on the caloric content, sugar composition, and alcohol content in beverages and food purchases bought before and after lockdown.

Predicting the onset of diabetes-related complications after a diabetes diagnosis with machine learning algorithms.

Aims: Using machine learning algorithms and administrative data, we aimed to predict the risk of being diagnosed with several diabetes-related complications after one-, two- and three-year post-diabetes diagnosis.

Methods: We used longitudinal data from administrative registers of 610,019 individuals in Catalonia with a diagnosis of diabetes and checked the presence of several complications after diabetes onset from 2013 to 2017: hypertension, renal failure, myocardial infarction, cardiovascular disease, retinopathy, congestive heart failure, cerebrovascular disease, peripheral vascular disease and stroke. Four different machine learning (ML) algorithms (logistic regression (LR), Decision tree (DT), Random Forest (RF), and Extreme Gradient Boosting (XGB)) will be used to assess their prediction performance and to evaluate the prediction accuracy of complications changes over the period considered.

Prevalence of atopic dermatitis in the adolescent population of Catalonia (Spain).

Background: Studies on the prevalence of atopic dermatitis (AD) for the adolescent cohort in general-based large populations are scarce worldwide. We performed a retrospective population--based observational cohort study of 76,665 adolescent patients diagnosed with AD in Catalonia (Spain). We studied the prevalence of AD by age, gender, disease severity, comorbidities, serum total immunoglobulin E (tIgE) and appropriate medical treatment (AMT) for the Catalan population.

Differential costs for the non-adult ADHD population in Catalonia.

Attention-Deficit/Hyperactivity Disorder (ADHD) is young children's most common mental health disorder. We aim to provide causal estimates of the differential costs for the non-adult population with ADHD. We used longitudinal administrative data covering the non-adult population over five years and different healthcare providers (general practitioners, hospitalisations and emergency departments, visits to mental healthcare centres-day-care or hospitals) of 1,101,215 individuals in Catalonia (Spain).

Direct health costs of amyotrophic lateral sclerosis in a multidisciplinary ALS unit in Catalonia (Spain).

Our research project computed the direct health costs of patients with amyotrophic lateral sclerosis (ALS) in a Spanish multidisciplinary unit and explored the main factors associated. Besides analyzing a context with universal health care provision, we used an administrative health care dataset from the most crucial center unit treating ALS in Catalonia (80% of total patients). Our results show that the direct health cost of caring for an ALS patient in our unit was 5,158€per patient/year.

The impact of an easy access drug supply management policy law on the consumption and abuse of opioids in Catalonia: A population-based study.

Background: Over the last two decades, the rise in opioid prescription has worsened health outcomes worldwide, increasing both levels of abuse and mortality rates. In order to reduce the scale of this public health problem, new policies have been implemented in many countries. In 2012, Spain adopted new legislation on opioid prescription (the ROE law), which meant that practitioners no longer needed to obtain extra authorisation in order to prescribe strong opioids.

Direct health care costs associated to neurological diseases and different degrees of malnutrition.

Background And Aims: Home-based care and oral supplemental nutrition may be an efficient way of managing health resources, freeing up hospital resources and improving patient care and quality of life. For some conditions, such as neurodegenerative diseases and acute neurological conditions, adequate nutritional control of patients at the time of discharge, with home monitoring by a home hospitalization unit (HHU), coupled with the introduction of necessary and appropriate oral nutritional supplements for each patient, is a good strategy for ensuring the efficiency of health resources. The aim of this paper is to analyse the direct health costs, considering home care and oral nutritional supplement, of patients with newly diagnosed neurological diseases and at risk of nutritional problems.

How do consumers respond to "sin taxes"? New evidence from a tax on sugary drinks.

It is unclear what the effects of taxes on sugar sweetened beverages (SSBs) are on consumer behaviour and which consumers may be affected the most. We evaluate the effect of the SSB tax introduced in Catalonia (but not in the rest of Spain) in May 2017 using loyalty card data of monthly purchases by 884,843 households from May 2016 to April 2018. Using a Difference-in-Differences approach, we study the SSB tax effect on the purchased quantity of beverages and sugar.

Social, economic and family factors associated with binge drinking in Spanish adolescents.

Background: The main aim of this study was to determine the socioeconomic and family factors associated with binge drinking (BD) in Spanish adolescents who participated in a web-based computer intervention for the prevention of binge drinking known as Alerta Alcohol.

Methods: Longitudinal analyses were carried out in a sample of Andalusian adolescents aged 15 to 19 enrolled in public schools, which was part of a two-arm cluster randomized controlled trial with an intervention group (IG) who received the Alerta Alcohol programme and a control group (CG) who did not receive any active intervention. Panel count data and the following econometric procedures were used: negative binomial, a two-part model and a finite mixture model.

Effectiveness and cost-effectiveness of Improving clinicians' diagnostic and communication Skills on Antibiotic prescribing Appropriateness in patients with acute Cough in primary care in CATalonia (the ISAAC-CAT study): study protocol for a cluster randomised controlled trial.

Background: Despite their marginal benefit, about 60% of acute lower respiratory tract infections (ALRTIs) are currently treated with antibiotics in Catalonia. This study aims to evaluate the effectiveness and efficiency of a continuous disease-focused intervention (C-reactive protein [CRP]) and an illness-focused intervention (enhancement of communication skills to optimise doctor-patient consultations) on antibiotic prescribing in patients with ALRTIs in Catalan primary care centres.

Methods/design: A cluster randomised, factorial, controlled trial aimed at including 20 primary care centres (N = 2940 patients) with patients older than 18 years of age presenting for a first consultation with an ALRTI will be included in the study.

Measuring the effects on quality of life and alcohol consumption of a program to reduce binge drinking in Spanish adolescents.

Results: We found 11 references.

Breakfast choice: An experiment combining a nutritional training workshop targeting adolescents and the promotion of unhealthy products.

A randomised control trial was conducted to determine changes in the food and drink choices of adolescents following their participation in a 50-min nutrition workshop. The experiment was conducted at 104 schools in Barcelona (126 classes, 3,291 adolescents). Schools were randomly selected and stratified by district and by public or private status.

Does health education affect BMI? Evidence from a school-based randomised-control trial.

We examine the effects of a comprehensive school-based health education programme (introducing healthy habits in the curriculum) to combat childhood obesity in the mid-size urban city of Granollers (Catalonia, Spain). The intervention was carried out between 2006 and 2008. New anthropometric measurements were obtained in 2008, 2010 and 2012.

The influence of obesity and overweight on medical costs: a panel data perspective.

This paper estimates the increase of direct medical costs of both severe and moderate obesity and overweight with respect to a normal-weight individual using a two-part generalised linear model and a longitudinal dataset of medical and administrative records of patients in primary and secondary healthcare centres followed up over seven consecutive years (2004-2010) in Spain. Our findings indicate that severe and moderate obesity imposes a substantial burden on the Spanish healthcare system. Specifically, being severely obese is associated with increases in medical costs of 26 % (instrumental variables (IV) estimate, 34 %) compared to a normal-weight individual.
