Vaccination against mumps in Portugal began in 1987, with the introduction of the combined measles, mumps, and rubella vaccine (MMR) in the national vaccination programme (Programa Nacional de Vacinação: PNV) for both sexes at 15 months. In November 1990,

The advent of new solid-state energy storage devices to tackle the electrical revolution requires the usage of nonlinear behavior leading to emergent phenomena. The ferroelectric analyzed herein belongs to a family of electrolytes that allow energy harvesting and storage as part of its self-charging features when thermally activated. The Na 2.99 Ba 0.005 ClO electrolyte shows quasi-adiabatic behavior with a continuous increase in polarization upon cycling, displaying almost no hysteresis. The maximum polarization obtained at a weak electric field is giant and similar to the remanent polarization. It depends on the temperature with a pyroelectric coefficient of 5.37 C m −2 °C−1 from −5 to 46 °C. The emergence occurs via negative resistance and capacitance. The glass transition is found to have its origins in the sharp depolarization at 46 -48 °C. Above -10 °C, at ≈ -5 °C, another thermal anomaly may rely on the topologic characteristics of the A 3-2x Ba x ClO (A = Li, Na, K) glass electrolytes enabling positive feedback of the current of electrons throughout the surface of the inner cell. The phenomena may pave the way toward a better understanding of dipolar nanodomain fragile glasses with exceptional ferroelectric characteristics to architect energy harvesting and storage devices based on multivalent thermally activated Na + -ion-ion electrolytes.

Introduction: Obstructive sleep apnea is a clinical entity that is associated with an increase in morbidity and mortality and it is estimated that it is significantly undiagnosed. The objective of this study was to assess the risk of undiagnosed obstructive sleep apneain obese individuals.Material and Methods: A descriptive and analytical cross-sectional study; the risk of obstructive sleep apnea’s was assessed over a period of 11 months by applying the STOP-Bang questionnaire to all individuals who attended a family health unit who were aged ≥ 18 years and had body mass index of ≥ 30 kg/m2 and who had not yet been diagnosed with obstructive sleep apnea and agreed to participate; the risk of an undiagnosed moderate to severe obstructive sleep apnea was considered for any STOP-Bang score of ≥ 3. Results: The risk of undiagnosed obstructive sleep apnea was assessed in 888 individuals (59.3% females) with an average age of 59.6 ± 14.68 years and a mean body mass index 33.6 ± 3.43 kg/m2; the mean STOP-Bang score was 3.5 ± 1.74, 70.9% scored ≥ 3; the frequency of all STOP-Bang questionnaire parameters was higher (p < 0.004) within the group with score ≥ 3.Discussion: The studied population is one of the main strengths, since it is in obese people that the incidence of this disease is higher. There are some limitations related to this sample coming from a single family health unit, as well as the patients’ follow-up being carried out throughout routine appointments for diseases that are closely related with obstructive sleep apnea.Conclusion: The level of underdiagnosis of obstructive sleep apnea’s in obese individuals can be significantly high and a large proportion of them may have the disease at a moderate to severe stage; Family Physicians can have a very important role in screening and diagnosis.

Primary prevention of cardiovascular diseases and promotion of active lifestyle should start early. Blood pressure (BP) in childhood correlates with BP in adulthood. The knowledge about children's physical activity influence on BP is limited. Aims:To analyse the relation between physical activity (PhyA) and time of "screen-activities" (ST) performed by children and BP.Methods: 428 children were enrolled, provided parent's consent. Measurements: BP: systolic (syst) and diastolic (diast) Z-score, pulse pressure (PP), mean pressure (PM). Activity information was obtained from: 1) a seven-day questionnaire, 2) the K13Plus PhyA and sedentary behaviour scale (K13 PhyS).Based on Z-score BP values participants were classified in: High-BP (HBP) ≥ 1.03 (n: syst=46, diast=100), Normal-BP (NBP) < 1.03 (n: syst=382, diast=328). Conclusions:-Children studied just reach current PhyA and "screen-time" recommendations.-PhyA have an effect on children´s BPvalues.-Mean time/day of moderate+vigorous PhyA seems to be the best preventive factor; inversely "screentime"/day.-PhyA and BP at childhood relationship must be considered as protective cardiovascular risk factors. Background and aims: Good oral hygiene habits should be implemented very soon in children's development. It is important to quantify the improvements and the dental plaque index can be an easy mean to do it. EVALUATION OF ORAL HYGIENE HABITS IN
