Injury prevention, drowning prevention habits and resuscitation knowledge of Portuguese surfing instructors. A cross-sectional study

Surfing instructors can play an important role both in preventing sport related injuries and as first responders in water emergencies events. Even though Portugal is a predominantly oceanic country, with many people enrolling in water sports activities, we still don’t have a clear insight of the knowledge and educational practices of surfing instructors concerning both injury prevention and first response actions. This study aimed to analyze the educational practices on prevention of surf-related injuries of Portuguese surfing instructors and their knowledge and experience acting as first responders in the sea. A cross-sectional study was designed, using an online survey distributed by all surfing schools registered at Portuguese Surfing Federation to their instructors. The survey included a brief demographic characterization, questions regarding teaching practices about prevention of surfing-related injuries and knowledge/experience acting as first responders at the sea. Data was collected anonymously using Google Forms. A total of 102 instructors participated in the study. The analysis of the survey responses showed that 93.2% of surfing instructors are aware of the importance of prevention habits for teaching but skip some major preventive measures when teaching novice surfers. Nevertheless, the instructors with more than 15 years of experience provide more feedback on prevention habits during classes than instructors with less experience (p=0.019). When looking at self-perceptions of own competence to act in a drowning event, the instructors who have attended a basic life support course asserted to be more competent than those who never attended a course (p<0.05). These findings suggest that it would be very positive that all surfing schools followed the same protocol, giving due importance to prevention measures. Moreover, surfing instructors can play an important role in first response to drowning events but might have some training flaws that should be considered as part of a Water Safety National Strategy. © JPES

Criteria for selecting children with special needs for dental treatment under general anaesthesia

Objective: To study criteria for helping to select children with special needs for dental treatment under general anaesthesia. Materials and methods: Group of 30 children (aged under 18) examined on the Course at the Universidad Complutense de Madrid (UCM) (Specialisation on holistic dental treatment of children with special needs) and subsequently referred to the Disabled Children?s Oral Health Unit (DCOHU) within Primary Health Care Area 2 of the Madrid Health Service (SERMAS) where dental treatment under general anaesthesia was given during 2005. Relevant data were taken from their case histories with regard to their general health, oral health and behaviour. Results: In most of the children (22 children), it was possible to carry out a complete dental diagnosis. With regard to medical diagnoses, the most frequent pathology was cerebral palsy (8 children), but it was not possible to establish a link between the pathology and the use of general anaesthesia. With regard to oral health, most of the children received restorative treatment in all 4 quadrants (26 children). On the basis of scales for behavioural evaluation and movement, most of the children (17 children) showed clearly negative behaviour, with movements that interrupted or hindered examination. Conclusions: With the exception of certain specific medical problems, the reasons for using general anaesthesia for dental treatment in children with special needs are extensive treatment needs and bad behaviour, both of which can be judged objectively

Program for coordinated dental care under general anaesthesia for children with special needs

Aim: To draw up a program for coordination of dental care for children with special needs between the Course at the Universidad Complutense de Madrid (UCMC) (Specialisation in holistic dental care for children with special needs), and the Disabled Children?s Oral Health Unit (DCOHU) within the Madrid Health Service (SERMAS). Material and methods: UCMC Protocol for children with special needs. Design of a clinical pathway based on consensus amongst the professionals involved. Results: Algorithm for dental care for children with special needs. Matrix covering all activities and timing for full dental diagnosis in such patients (general health, oral health and behaviour) to facilitate proper referral of patients requiring general anaesthesia. Inclusion in the matrix of those responsible for each activity. Conclusions: Improved team work (University ? primary health care) in patient evaluation, in provision of information to parents and guardians and in health care quality. From the teaching point of view, students learn to adopt a systematic approach in the decision-making process

A genetic case-control study confirms the implication of SMAD7 and TNF locus in the development of proliferative vitreoretinopathy

PURPOSE: Proliferative vitreoretinopathy (PVR) is still the major cause of failure of retinal detachment (RD) surgery and although the risk for developing this complication is associated with some clinical characteristics, the correlation is far from absolute, raising the possibility of genetic susceptibility. The objective of this study was to analyze the genetic contribution to PVR in patients undergoing RD surgery, the Retina 4 Project. METHODS: A candidate gene association study was conducted in 2006 in a Spanish population of 450 patients suffering from primary rhegmatogenous RD. Replication was carried out in a larger population undergoing RD surgery at several European centers among 546 new patients. Single nucleotide polymorphism (SNP) of 30 genes known to be involved with inflammation were analyzed. For replication stage, those genes previously detected as significantly associated with PVR were genotyped. Distribution of allelic and haplotypic frequencies in case and control group were analyzed. Single and haplotypic analysis were assessed. The Rosenberg two-stage method was used to correct for single and multiple analyses. RESULTS: After correction for multiple comparisons, four genes were significantly associated with PVR: SMAD7 (P = 0.004), PIK3CG (P = 0.009), TNF locus (P = 0.0005), and TNFR2 (P = 0.019) In the European sample, replication was observed in SMAD7 (P = 0.047) and the TNF locus (P = 0.044). CONCLUSIONS: These results confirm the genetic contribution to PVR and the implication of SMAD7 and TNF locus in the development of PVR. This finding may have implications for understanding the mechanisms of PVR and could provide a potential new therapeutic target for PVR prophylaxis

Inadequate use of antibiotics in the covid-19 era: effectiveness of antibiotic therapy

Background: Since December 2019, the COVID-19 pandemic has changed the concept of medicine. This work aims to analyze the use of antibiotics in patients admitted to the hospital due to SARS-CoV-2 infection. Methods: This work analyzes the use and effectiveness of antibiotics in hospitalized patients with COVID-19 based on data from the SEMI-COVID-19 registry, an initiative to generate knowledge about this disease using data from electronic medical records. Our primary endpoint was all-cause in-hospital mortality according to antibiotic use. The secondary endpoint was the effect of macrolides on mortality. Results: Of 13, 932 patients, antibiotics were used in 12, 238. The overall death rate was 20.7% and higher among those taking antibiotics (87.8%). Higher mortality was observed with use of all antibiotics (OR 1.40, 95% CI 1.21–1.62; p <.001) except macrolides, which had a higher survival rate (OR 0.70, 95% CI 0.64–0.76; p <.001). The decision to start antibiotics was influenced by presence of increased inflammatory markers and any kind of infiltrate on an x-ray. Patients receiving antibiotics required respiratory support and were transferred to intensive care units more often. Conclusions: Bacterial co-infection was uncommon among COVID-19 patients, yet use of antibiotics was high. There is insufficient evidence to support widespread use of empiric antibiotics in these patients. Most may not require empiric treatment and if they do, there is promising evidence regarding azithromycin as a potential COVID-19 treatment. © 2021, The Author(s)

Spain

This chapter presents a review of the situation concerning the various geomorphological hazards in the country, including some information about existing programmes for research, control and mitigation. With its great variety of climatic, geological and morphodynamic environments, Spain is subject to every kind of natural hazard: tsunamis, floods, volcanism, and mass movements. The whole of the territory is prone to some kind of geomorphological hazard but it is in the eastern and southern coastal strips that the risks are greatest. One of the main problems for the mitigation of geomorphological hazards in Spain is the lack of an appropriate regulatory framework for the incorporation of natural hazard assessments into land-use planning and management at the macro-, meso- and micro-planning levels. The coverage of hazard mapping is still far from complete or adequate, and much work remains to be done. There has been considerable diversity in the methods used for risk assessment and for the cartographic representation of natural hazards. An urgent need is to establish common, accepted methodologies and criteria, based on indicators defined as clearly as possible, and to standardize map legends and scales for different planning levels. Information programmes for the general public also need to be considerably expanded

A crowdsourcing database for the copy-number variation of the spanish population

Background: Despite being a very common type of genetic variation, the distribution of copy-number variations (CNVs) in the population is still poorly understood. The knowledge of the genetic variability, especially at the level of the local population, is a critical factor for distinguishing pathogenic from non-pathogenic variation in the discovery of new disease variants. Results: Here, we present the SPAnish Copy Number Alterations Collaborative Server (SPACNACS), which currently contains copy number variation profiles obtained from more than 400 genomes and exomes of unrelated Spanish individuals. By means of a collaborative crowdsourcing effort whole genome and whole exome sequencing data, produced by local genomic projects and for other purposes, is continuously collected. Once checked both, the Spanish ancestry and the lack of kinship with other individuals in the SPACNACS, the CNVs are inferred for these sequences and they are used to populate the database. A web interface allows querying the database with different filters that include ICD10 upper categories. This allows discarding samples from the disease under study and obtaining pseudo-control CNV profiles from the local population. We also show here additional studies on the local impact of CNVs in some phenotypes and on pharmacogenomic variants. SPACNACS can be accessed at: http://csvs.clinbioinfosspa.es/spacnacs/. Conclusion: SPACNACS facilitates disease gene discovery by providing detailed information of the local variability of the population and exemplifies how to reuse genomic data produced for other purposes to build a local reference database.This work is supported by Grants PID2020-117979RB-I00 from the Spanish Ministry of Science and Innovation; by the Institute of Health Carlos III (project IMPaCT-Data, exp.

Urban air pollution and emergency room admissions for respiratory symptoms: a case-crossover study in Palermo, Italy

<p>Abstract</p> <p>Background</p> <p>Air pollution from vehicular traffic has been associated with respiratory diseases. In Palermo, the largest metropolitan area in Sicily, urban air pollution is mainly addressed to traffic-related pollution because of lack of industrial settlements, and the presence of a temperate climate that contribute to the limited use of domestic heating plants. This study aimed to investigate the association between traffic-related air pollution and emergency room admissions for acute respiratory symptoms.</p> <p>Methods</p> <p>From January 2004 through December 2007, air pollutant concentrations and emergency room visits were collected for a case-crossover study conducted in Palermo, Sicily. Risk estimates of short-term exposures to particulate matter and gaseous ambient pollutants including carbon monoxide, nitrogen dioxide, and sulfur dioxide were calculated by using a conditional logistic regression analysis.</p> <p>Results</p> <p>Emergency departments provided data on 48,519 visits for respiratory symptoms. Adjusted case-crossover analyses revealed stronger effects in the warm season for the most part of the pollutants considered, with a positive association for PM₁₀(odds ratio = 1.039, 95% confidence interval: 1.020 - 1.059), SO₂(OR = 1.068, 95% CI: 1.014 - 1.126), nitrogen dioxide (NO₂: OR = 1.043, 95% CI: 1.021 - 1.065), and CO (OR = 1.128, 95% CI: 1.074 - 1.184), especially among females (according to an increase of 10 μg/m³in PM₁₀, NO₂, SO₂, and 1 mg/m³in CO exposure). A positive association was observed either in warm or in cold season only for PM₁₀.</p> <p>Conclusions</p> <p>Our findings suggest that, in our setting, exposure to ambient levels of air pollution is an important determinant of emergency room (ER) visits for acute respiratory symptoms, particularly during the warm season. ER admittance may be considered a good proxy to evaluate the adverse effects of air pollution on respiratory health.</p
