Introduction Little is known about the state of oral health among immigrants from conflict zones, such as the refugee children from the Syrian Civil War. Aim To determine the oral health status of Syrian immigrant children refugee at the Center for Temporary Stay of Immigrants in Melilla to plan prevention and care programs. Design Using the criteria set by the World Health Organization, an exploration of the oral cavity of all Syrian children aged 5–13 living at that center was conducted in May 2015. All subjects were clinically evaluated by a calibrated and standardized examiner, accompanied by a dentist who registered the clinical variables, and translators. The sociodemographic and clinical variables were analyzed through a descriptive and analytical study, respectively. Results The prevalence of caries in both the permanent and deciduous dentition was 75% and 50% in 6- and 12-year-olds, respectively. The dft was 3.2 ± 2.9 in 6-year-old children. At 12 years old, the DMFT was 1.6 ± 2.6 teeth, the DMFM was 1.1 ± 1.7 teeth, the SiC was 3.2, and the IR was 5%. Eighty-six percent of the examined sextants were periodontally healthy. Conclusions The prevalence of caries was high in the sample population studied, confirming the need for a comprehensive primary oral health care program.

Cefepime is an antibiotic with a broad spectrum of antimicrobial activity. However, this antibiotic has several side effects and a high degradation rate. For this reason, the preparation and characterization of new liposomes that are able to encapsulate this antibiotic seem to be an important research line in the pharmaceutical industry. Anionic and cationic liposomes were prepared and characterized. All cationic structures contained the same cationic surfactant, N,N,N-triethyl-N-(12-naphthoxydodecyl)ammonium. Results showed a better encapsulation-efficiency percentage (EE%) of cefepime in liposomes with phosphatidylcholine and cholesterol than with 1,2-dioleoyl-sn-glycero-3-phosphoethanolamine (DOPE). The presence of cholesterol and the quantity of egg-yolk phospholipid in the liposome increased the encapsulation percentage. The bactericidal activity against Escherichia coli of cefepime loaded into liposomes with phosphatidylcholine was measured. The inhibitory zone in an agar plate for free cefepime was similar to that obtained for loaded cefepime. The growth-rate constant of E. coli culture was also measured in working conditions. The liposome without any antibiotic exerted no influence in such a rate constant. All obtained results suggest that PC:CH:12NBr liposomes are biocompatible nanocarriers of cefepime that can be used in bacterial infections against Escherichia coli with high inhibitory activity.

Graduates' employability indicates the excellent education and relevant preparation they obtained from their respective degrees. Tracer studies have enabled higher education institutions to profile their graduates while also reflecting on the quality of education they provide. With the foregoing, a tracer study determined the demographic and academic profile of teacher education graduates from 2017 to 2020 in a state university in the West Philippines. It also ascertained the advanced studies they attended after college, their employment data, the relevance of college preparation with their current employment, difficulties they encountered while securing employment and in their present job, and recommendations to strengthen the teacher education program. The study utilized a descriptive survey research design with 80 non-random samples chosen based on availability. The survey was based on the Philippine Commission on Higher Education with modifications elucidated from previous studies. Results showed that graduates took the teacher education program with a strong passion for the teaching profession. More graduates received honors and awards, passed the licensure examinations for teachers, attended advanced studies for professional development, and are employable. Besides, the graduates’ college preparation is relevant to their current employment. Further, difficulties and problems encountered and recommendations to strengthen the teacher education program were noted. These findings may serve as a baseline for curriculum review and give suggestions for future tracer studies.

The high incidence of childhood dental trauma requires childcare professionals to have basic notions of dental first aid. The aim of this study is to assess the level of knowledge and aptitude (defined as the ability to operate competently in a given activity) of early childhood, primary, and/or secondary education teachers from Seville (Spain) referred to first aid measures in dental trauma. A descriptive study was conducted. The study sample consisted of 442 teachers (334 women and 108 men) coinciding proportionately with the study target population in terms of gender distribution, type of center, and teaching level. A specifically designed questionnaire was used. Most of the participants (88.5%, n = 391) exhibited poor knowledge and aptitude, 11.5% (n = 51) showed a medium level of knowledge and aptitude, and none were categorized as having a high knowledge and aptitude. As a conclusion, teachers in the province of Seville (Spain) showed marked deficiencies in their level of knowledge and aptitude referred to the adoption of first aid measures in dental trauma among their pupils.

The increasing size of the elderly population in Spain underlines the need for the dental profession to pay particular attention to the oral health needs of older patients. The aim of this study was to perform a preliminary assessment of the Geriatric Dentistry education programs in Spanish dental schools and highlight the models being employed for the geriatric training programs in these schools. The assessment was designed to be a cross-sectional study, which involved all the dental schools (n = 19) in Spain. Using a simple, 12-item questionnaire, information regarding the geriatric dental education programs in the schools was collected from their official websites by researchers from the University of Seville. In the first instance, the information was collected from the dental schools' websites and included the history, frequency and characteristics of the geriatric dental program. The deans or their deputies from those schools with a geriatric dental education programme were then asked to validate the data obtained from the websites. Only eight (42%) of schools offered a specific geriatric dentistry course. Seven of these schools were public and only one was private. The other 11 Spanish dental schools (five public and six private) did not offer a specific geriatric dentistry course. Seven out of the eight schools taught the course using a didactic teaching method and none of these seven included a clinical component in the program. No school had a specific geriatric dentistry clinic within the school, neither did they run geriatric clinics at remote locations or operate mobile dental clinics for geriatric patients. This study has described the current provision of dental undergraduate education in geriatric dentistry in Spain. The results suggest that there is a need to develop the curriculum content, design, implementation and evaluation of geriatric dentistry programs. Research should also focus on assessing the access to and improvement in the oral care of the elderly population.

Inhaled corticosteroids (ICSs) are widely used in chronic obstructive pulmonary disease (COPD) and in combination with long-acting β2 agonists (LABAs) to reduce exacerbations and improve patient lung function and quality of life. However, ICSs have been associated with an increased risk of pneumonia in individuals with COPD, although the magnitude of this risk remains unclear. Therefore, it is difficult to make informed clinical decisions that balance the benefits and adverse effects of ICSs in people with COPD. There may be other causes of pneumonia in patients with COPD, and these causes are not always considered in studies on the risks of using ICSs in COPD. We consider it very useful to clarify these aspects in assessing the influence of ICSs on the incidence of pneumonia and their role in the treatment of COPD. This issue has important implications for current practice and the evaluation and management of COPD, since COPD patients may benefit from specific ICS-based treatment strategies. Many of the potential causes of pneumonia in patients with COPD can act synergistically, so they can be included in more than one section.

BackgroundNeutrophils are involved in the pathophysiology of allergic asthma, where the Eosinophil Cationic Protein (ECP) is a critical inflammatory mediator. Although ECP production is attributed to eosinophils, we reported that ECP is also present in neutrophils from allergic patients where, in contrast to eosinophils, it is produced in an IgE-dependent manner. Given the key role of ECP in asthma, we investigated the molecular mechanisms involved in ECP production as well as the effects induced by agonists and widely used clinical approaches. We also analyzed the correlation between ECP production and lung function.MethodsNeutrophils from allergic asthmatic patients were challenged with allergens, alone or in combination with cytokines, in the presence of cell-signaling inhibitors and clinical drugs. We analyzed ECP levels by ELISA and confocal microscopy. Lung function was assessed by spirometry.ResultsIgE-mediated ECP release is dependent on phosphoinositide 3-kinase, the extracellular signal-regulated kinase (ERK1/2) and the production of reactive oxygen species by NADPH-oxidase. Calcineurin phosphatase and the transcription factor NFAT are also involved. ECP release is enhanced by the cytokines interleukin (IL)-5 and granulocyte macrophage-colony stimulating factor, and inhibited by interferon-γ, IL-10, clinical drugs (formoterol, tiotropium and budesonide) and allergen-specific IT. We also found an inverse correlation between asthma severity and ECP levels.ConclusionsOur results suggest the molecular pathways involved in ECP production and potential therapeutic targets. We also provide a new method to evaluate disease severity in asthmatic patients based on the quantification of in vitro ECP production by peripheral neutrophils.
