ABSTRACT

OBJECTIVES: To determine the prevalence of suspected abuse of non-institutionalised elderly people and the associated variables. PATIENTS AND METHOD: Observational, descriptive, cross-sectional, multicentre study in patients aged 65 years or older, non-institutionalised, consecutively selected in primary care (PC). The EASI questionnaires (Suspected Elderly Abuse Index), the EAI questionnaire (Suspected Abuse Index in patients with cognitive impairment), the Barthel index, and the EUROQOL-5D questionnaire were used with patients, and the CASE questionnaire and the Zarit test were used with caregivers. Socio-demographic, health, and quality of life variables were analysed in all patients. RESULTS: Eight hundred four patients were included, mean age 78.9±7.9 years, 58.3% women. The prevalence of suspected abuse was 11.3% (95% CI: 9.1%-13.9%). Suspected abuse was more frequent in women than in men (14.4% vs. 7.1%; odds ratio (OR)=1.97; 95% CI=1.1-3.4; p=0.016) and in those who lived with two or more people compared to those who lived alone (18.4% vs. 7.3%; OR=2.42; 95% CI=1.1-5.0; p=0.017). Among older patients, the lower their dependency, the lower the prevalence of suspected abuse (30.0% in highly dependent vs. 8.7% in non-dependent: p-trend=0.006); and the better the perceived health status, the lower the prevalence of suspected abuse (29.6% in poor health status vs. 6.9% in optimal health status; p-trend=<0.001). Among caregivers, the prevalence of suspected abuse was 20.4% (95% CI=12.8%-28.0%). A trend of higher prevalence of suspected abuse could be observed with higher scores on the CASE questionnaire (56.3% at high risk and 9.6% with no risk of abuse; p-trend=0.007). In the case of the ZARIT questionnaire with scores below 47, the prevalence of suspected abuse was 9.1%, and for scores above 55, it was 52.6% (p-trend<0.001). CONCLUSIONS: The results of the PRESENCIA study show that approximately 1 in 10 patients aged ≥65 meet the criteria for suspected abuse. The probability of abuse increases in women, in patients with greater dependency and in patients with poorer perceived health status. Caregivers with greater overload and greater risk presented a greater suspicion of elder abuse.

ABSTRACT

BACKGROUND: Oral lichen planus (OLP) is an inmuno-mediated mucocutaneous chronical inflammatory disease. Multiple predisposing factors are considered, such as autoimmune response, microorganisms, medications, dental materials, psychological stress, genetic predisposition or nutritional deficiencies. The deficiency of vitamin D has been related to various autoimmune diseases like OLP. MATERIAL AND METHODS: The electronic search was conducted in the MEDLINE (Pubmed), Scopus, Cochrane Library and Web of Science databases. To assess any potential risk of bias, the authors critically appraised each study by the Newcastle-Ottawa Scale for cohort and case-control studies. Pooled analyses were performed using a random-effects model. Heterogeneity of the studies was assessed by the I2 statistics. Forest Plots were performed to graphically represent the difference between vitamin D concentrations in the OLP compared to healthy group, with a 95% confidence interval. RESULTS: After applying our inclusion and exclusion criteria, 7 articles were included in our review. The median concentration vitamin D in ng/ml found in serum for patients with OLP was of 26,6311,75ng/ml and for healthy patients was of 31,438,7ng/ml. Regarding the quantitative analysis, 7 studies were included. The difference in the concentration of vitamin D in healthy patients and patients with OLP statistically significant (Weighted Mean Difference (WMD): -6.20, 95% CI: -11.24 to -1.15, p=0.02 and I2 heterogeneity: 94%, p<0.00001). CONCLUSIONS: The patients with OLP have statistically lower vitamin D levels than healthy patients.

ABSTRACT

The allergenicity and protein risk assessments in food safety are facing new challenges. Demands for healthier and more sustainable food systems have led to significant advances in biotechnology, the development of more complex foods, and the search for alternative protein sources. All this has increased the pressure on the safety assessment prediction approaches anchored into requirements defined in the late 90's. In 2022, the EFSA's Panel on Genetically Modified Organisms published a scientific opinion focusing on the developments needed for allergenicity and protein safety assessments of new products derived from biotechnology. Here, we further elaborate on the main elements described in this scientific opinion and prioritize those development needs requiring critical attention. The starting point of any new recommendation would require a focus on clinical relevance and the development of a fit-for-purpose database targeted for specific risk assessment goals. Furthermore, it is imperative to review and clarify the main purpose of the allergenicity risk assessment. An internationally agreed consensus on the overall purpose of allergenicity risk assessment will accelerate the development of fit-for-purpose methodologies, where the role of exposure should be better clarified. Considering the experience gained over the last 25 years and recent scientific developments in the fields of biotechnology, allergy, and risk assessment, it is time to revise and improve the allergenicity safety assessment to ensure the reliability of allergenicity assessments for food of the future.

ABSTRACT

BACKGROUND: Traditional protocols for implant surgery suggest a healing period of 2-3 months from dental extraction to implant placement. Based on all the volumetric modifications produced by that approach, there are authors who advocate for immediate implantology. The aim of the present study was to determine the prevalence of different sockets, and the dimensions of the bone around the upper anterior incisors and canines, to determine the predictability of immediate implants in our population. MATERIAL AND METHODS: This is an observational, cross-sectional study based on cone-beam computed tomography images of the anterior maxila of patients attending the Odontological Hospital of the University of Barcelona (OHUB) and requesting for implant treatment. Different measurements were performed on every analyzed tooth, and also they were categorized by using the main dental sockets classifications. RESULTS: Bone attachment levels and cortical thickness are lower in women compared to men in all three types of teeth (the difference in the bone attachment levels ranges from 4.68%-8.63% and in the bone thickness goes from 0.02-0.58mm). Bone attachment level gradually reduces with age. The reductions observed in all the measurements are higher in the case of canines, compared with the other teeth. The differences from patients <45 years old and patients between 55-64 years old are 13.58±14.55mm in the case of central incisors, 10.04±5.52 in the case of lateral incisors and 22.39±13.65mm in the case of canines. CONCLUSIONS: According to our results, the canines are the teeth with the greatest complexity when it comes to immediate implantology treatments. Furthermore, that kind of treatment is more complex as age increases, since we observed a gradual percentage of unfavourable sockets in older patients.

ABSTRACT

BACKGROUND/OBJECTIVES: Study of retinal structure based on optical coherence tomography (OCT) data can facilitate early diagnosis of relapsing-remitting multiple sclerosis (RRMS). Although artificial intelligence can provide highly reliable diagnoses, the results obtained must be explainable. SUBJECTS/METHODS: The study included 79 recently diagnosed RRMS patients and 69 age matched healthy control subjects. Thickness (Avg) and inter-eye difference (Diff) features are obtained in 4 retinal layers using the posterior pole protocol. Each layer is divided into six analysis zones. The Support Vector Machine plus Recursive Feature Elimination with Leave-One-Out Cross Validation (SVM-RFE-LOOCV) approach is used to find the subset of features that reduces dimensionality and optimises the performance of the classifier. RESULTS: SVM-RFE-LOOCV was used to identify OCT features with greatest capacity for early diagnosis, determining the area of the papillomacular bundle to be the most influential. A correlation was observed between loss of layer thickness and increase in functional disability. There was also greater functional deterioration in patients with greater asymmetry between left and right eyes. The classifier based on the top-ranked features obtained sensitivity = 0.86 and specificity = 0.90. CONCLUSIONS: There was consistency between the features identified as relevant by the SVM-RFE-LOOCV approach and the retinotopic distribution of the retinal nerve fibres and the optic nerve head. This simple method contributes to implementation of an assisted diagnosis system and its accuracy exceeds that achieved with magnetic resonance imaging of the central nervous system, the current gold standard. This paper provides novel insights into RRMS affectation of the neuroretina.

ABSTRACT

Objetivo Describir las percepciones y las experiencias cotidianas de los médicos de atención primaria (AP) en el abordaje de la falta de adherencia terapéutica en pacientes con riesgo cardiovascular, así como sus expectativas y las posibles áreas de mejora. Material y métodos Estudio cualitativo (en el marco del proyecto REAAP: Red de Expertos en Adherencia de Atención Primaria) realizado en varias comunidades autónomas de España a partir de un cuestionario de respuesta abierta completado por médicos de AP. Los escritos se analizaron mediante el método marco o Framework Analysis para orientar la codificación de los temas. Resultados Participaron 18 médicos, de cuyas respuestas se identificaron tres temas principales: abordaje de la adherencia durante la práctica clínica, barreras que dificultan una correcta adherencia e intervenciones para mejorar la adherencia. Las estrategias más señaladas para facilitar la adherencia terapéutica de los pacientes fueron: mejorar la comunicación médico-paciente y la continuidad asistencial, involucrar a las farmacias comunitarias y simplificar el tratamiento prescribiendo fármacos a combinaciones fijas. Conclusiones Los médicos asistenciales de AP apuntan a que no existe una estrategia ideal que por sí sola facilite la adherencia terapéutica, siendo necesario combinar varias intervenciones para optimizarla. Conocer la problemática y las herramientas disponibles y ausentes en la práctica habitual permitirá un mejor abordaje de la adherencia de los pacientes. En esta línea, iniciativas como el proyecto REAAP son un medio importante para que el personal sanitario, y el resto de actores implicados reconozcan la importancia que merece esta cuestión (AU)


Objective To describe the perceptions and daily experiences of primary care (PC) physicians in dealing with the lack of therapeutic adherence in patients with cardiovascular risk, as well as their expectations and possible areas for improvement. Material and methods A qualitative study (within the framework of the REAAP project: Network of Experts in Adherence in Primary Care) carried out in several autonomous communities in Spain using an open-ended questionnaire completed by PC physicians and analyzed using the framework analysis method to guide the coding of the topics. Results Eighteen physicians participated, and three main themes were identified from their responses: an approach to adherence during clinical practice, barriers that hinder the appropriate adherence, and interventions to improve it. The strategies most frequently mentioned to facilitate patients’ therapeutic adherence were improving physician-patient communication and continuity of care, involving community pharmacies, and simplifying treatment by prescribing drugs in fixed combinations. Conclusions There is no single ideal strategy to facilitate therapeutic adherence, and it is necessary to combine several interventions to optimize it. The first step is to understand the problems and the tools available. Initiatives such as the REAAP project are an important means to improve patient adherence, and for healthcare personnel to recognize the importance that this issue deserves (AU)

ABSTRACT

The method typically used to diagnose and monitor hypertensive patients has been to measure blood pressure in the physician's surgery; however, it is a well-known fact that this approach poses certain drawbacks, such as observer bias, failure to detect an alert reaction in the clinic, etc., difficulties that affect its accuracy as a diagnostic method.In recent years, the varying international scientific societies have persistently recommended the use of blood pressure measurements outside the clinic (at home or in the outpatient setting), using validated automatic devices. Data from some studies suggest that if we rely solely on in-office measurements, approximately 15–20% of the time we may be wrong when making decisions, both in terms of diagnosis and patient follow-up.Home blood pressure measurements are a simple and very affordable method that has a similar reproducibility and prognostic value as ambulatory blood pressure monitoring, the availability of which is currently very limited. Moreover, ambulatory self-measurements have the significant benefit of being able to improve control of hypertensive individuals.Healthcare professionals and patients should be aware of the methodology of home blood pressure measurement, its usefulness and limitations. (AU)


El método utilizado habitualmente para el diagnóstico y seguimiento de los pacientes hipertensos ha sido la medida de la presión arterial en la consulta, pero es un hecho conocido que este método plantea problemas (sesgos del observador, no detecta reacción de alerta en consulta…) que afectan a su precisión como método diagnóstico.Las diferentes sociedades científicas internacionales, en los últimos años, recomiendan de forma insistente el uso de medidas de presión arterial fuera de la consulta (domiciliarias o ambulatorias) con aparatos automáticos validados para tomar decisiones. Datos de algunos estudios sugieren que si solo utilizamos las medidas de la consulta nos podemos equivocar en torno a un 15-20% de las veces que tomemos decisiones en el diagnóstico y seguimiento de los pacientes.Las medidas domiciliarias de presión arterial son un método sencillo y muy accesible que tienen una reproducibilidad y valor pronóstico similar al de las medidas ambulatorias, cuya disponibilidad actualmente e muy limitada, y que además tienen una utilidad importante que es la posibilidad de mejora del control de los hipertensos.Los profesionales sanitarios y los pacientes deben conocer la metodología de uso de la medida de presión arterial domiciliaria y sus utilidades y limitaciones.

ABSTRACT

BACKGROUND: Recurrent Aphtous Stomatitis (RAS) is the most common process affecting the oral mucosa. It is painful, multifactorial and generally recurrent. The aim of this systematic review is to know the last treatment approaches and their effectivity. MATERIAL AND METHODS: we compared the outcome of different kind of treatments in terms of the improvement of the lesions, reduction of the size of those lesions and the time needed for their healing. Inclusion criteria were: clinical trials, articles written in English or Spanish and published less than 5 years ago. RESULTS: we used the following keywords: "treatment", "aphtous stomatitis", "canker sores"; combined with Boolean operators AND y OR. We selected 28 articles for reading the whole text, and after applying the eligibility criteria, we selected 17 articles for our revision. Among all the treatments, we emphasize the barrier method based in compound of cellulose rubber and a calcium/sodium copolymer PVM/MA, with which the difference in the 3rd and 7th day was of -6,29 ± 0,14 points in the pain score. The treatment with insulin and chitosan gel, brought a pain suppression on the third day, with no reactivation of the pain during the whole study. The application of a film composed of polyurethane and sesame oil with chitosan, brought a reduction in the size of the lesions of 4,54 ± 2,84mm on the 6th day compared with the situation before the beginning of the treatment. The different kinds of laser, which produced a reduction in the pain score just at the beginning of the treatment up to 8,1 ± 1,6 points, and a reduction of the size of the lesions of 4,42 ± 1,02mm on the 7th day. CONCLUSIONS: Besides the classic treatments for RAS, we have to take into account other treatment modalities, above all the different kinds of laser.

ABSTRACT

In this study we show the results of the eagle owls' (Bubo bubo) helminthfauna found in Andalusia. A total number of 50 specimens have been analysed in a period of 10 years (from 2011 to 2020). Prevalence ( P % ), mean intensity (IM) and mean abundance (AM) of parasitation have been obtained. The percentage of parasitation in the total sample was 80% (40 out of 50 eagle owls): 78% nematodes, 8% trematodes, 6% cestodes and 4% acantocephalans. 7 species of helminths were identified: 6 nematodes, and 1 trematode. In the case of cestodes and acantocephalans it was not possible to determine species and only the genus was identified. The intestinal nematode Capillaria tenuissima ( P %  = 58% (44-71.2); IM = 11,52 (5.83-28.9)) was the core species whereas Synhimantus laticeps (P% = 16 (7.5-28.8); IM = 4 (1.75-7.25)) and Hartertia hispanica (P% = 16 (7.5-28.8); IM = 1,5 (1-2)) were the secondary species. The remainder species were considered satellite species, with low prevalence and average abundance. Likewise, descriptive parameters of the helminth community were determined: species richness, 1.56 (1.29-1.94), total abundance, 12 (7.24-26.40), Brillouin's diversity index, 0.18 (0.10-0.29) and Berger-Parker dominance index, 0.88 (0.81-0.93). The data from this study show a non-diverse helminthic community, without species dominance with C. tenuissima as the central species, followed by S. laticeps and H. hispanica as secondary species. Worth mentioning is the presence of H. hispanica, which is considered an endemic species in Spain and specifically in Andalusia. To the authors' knowledge, this is the largest population sample taken in parasitological studies about helminths of this raptor in Europe and the first one carried out in the south of Spain (Andalusia).

ABSTRACT

Background: The efficacy and safety of acetylsalicylic acid (ASA) prophylaxis for the primary prevention of atherosclerotic cardiovascular disease (ACVD) remain controversial in people with diabetes (DM) without ACVD, because the possible increased risk of major bleeding could outweigh the potential reduction in the risk of mortality and of major adverse cardiovascular events (MACE) considered individually or together. Objective: To evaluate the overall risk-benefit of ASA prophylaxis in primary prevention in people with DM and to compare the recommendations of the guidelines with the results of the meta-analyses (MA) and systematic reviews (SR). Material and methods: We searched Medline, Google Scholar, Embase, and the Cochrane Library for SR and MA published from 2009 to 2020 which compared the effects of ASA prophylaxis versus placebo or control followed up for at least one year in people with DM without ACVD. Heterogeneity among the randomized clinical trials (RCT) included in the SR and MA was assessed. Cardiovascular outcomes of efficacy (all-cause mortality [ACM], cardiovascular mortality [CVM], myocardial infarction [MI], stroke and MACE) and of safety (major bleeding events [MBE], major gastrointestinal bleeding events [MGIBE], and intracranial and extracranial bleeding) were shown. Results: The recommendations of 12 guidelines were evaluated. The results of 25 SR and MA that included a total of 20 RCT were assessed. None of the MA or SR showed that ASA prophylaxis decreased the risk of ACM, CVM or MI. Only two of the 19 SR and MA that evaluated ischemic stroke showed a decrease in the stroke risk (mean 20.0% [SD±5.7]), bordering on statistical significance. Almost half of the MA and SR showed, bordering on statistical significance, a risk reduction for the MACE composite endpoint (mean 10.5% [SD±3.3]). The significant increases in MGIBE risk ranged from 35% to 55% (AU)


Antecedentes: La eficacia y la seguridad de la profilaxis con ácido acetilsalicílico (AAS) para la prevención primaria de la enfermedad cardiovascular arteriosclerótica (ECVA) siguen siendo controvertidas en personas con diabetes (DM) sin ECVA, ya que el posible aumento del riesgo de hemorragias graves podría superar la posible disminución del riesgo de mortalidad y de los principales episodios adversos cardiovasculares (MACE) considerados individualmente o en conjunto. Objetivo: Evaluar el riesgo-beneficio de la profilaxis con AAS en prevención primaria en personas con DM y comparar las recomendaciones de las guías de práctica clínica con los resultados de los metaanálisis (MA) y revisiones sistemáticas (RS). Material y métodos: Se realizaron búsquedas en Medline, Google Scholar, Embase y Biblioteca Cochrane de RS y MA publicados desde 2009 hasta 2020 que compararan los efectos de AAS versus placebo o control en seguimiento durante al menos un año en personas con DM sin ECVA. Se valoraron la heterogeneidad entre los ensayos clínicos aleatorizados (ECA) incluidos en las RS y MA. Se mostraron los resultados cardiovasculares de eficacia (muerte por cualquier causa [MCC], muerte cardiovascular [MCV], infarto de miocardio [IM], ictus y MACE) y de seguridad (episodios hemorrágicos importantes [EHI], episodios hemorrágicos gastrointestinales importantes [EHGI], hemorragias intracraneales y extracraneales). Resultados: Se valoraron las recomendaciones de 12 guías de práctica clínica. Se evaluaron los resultados de 25 RS y MA que incluyeron un total de 20ECA. Ningún MA ni RS mostró que la profilaxis con AAS disminuyera el riesgo de MCC, MCV o IM. Solo dos de los 19 SR y MA que evaluaron el ictus isquémico mostraron una disminución en el riesgo de ictus (media 20,0% [DE±5,7]), rozando la significación estadística (AU)

ABSTRACT

The complexity of the center of pressure (COP) provides important information regarding the underlying mechanisms of postural control. The relationships between COP complexity and balance performance are not fully established and might depend on the task constraints and the filtering decomposition of the COP signal. This study assessed COP complexity under different task constraints and it was assessed if emergent dynamics of COP fluctuations differ according to fractional components of COP related to peripheral or central adjustments. One hundred and sixty-two participants performed two sitting balance tasks. Accuracy was required by following a target that moved in the mediolateral (ML) or in the anteroposterior (AP) axis. Complexity dynamics of COP were addressed through detrended fluctuation analysis (DFA) in the axis constrained by accuracy requirements and in the one nonconstrained. Decomposition of COP components was applied by low-pass, band-pass, and high-pass filters. DFA of low-pass and band-pass components of COP in the constrained axis were small-to-moderately related (r = 0.190-0.237) to balance performance. DFA of the high-pass component of the COP exhibited the opposite relationship (r = -0.283 to -0.453) in both axes (constrained and nonconstrained). This study evidences that COP complexity is linked to better performance. This positive relationship complexity/performance is observed in the low- and mid-frequency components of the COP. These components might be related to central mechanisms of postural control. The lack of relationships between the different frequencies analyzed in the study suggests that they are capturing different components of postural control.NEW & NOTEWORTHY The relationship between the complexity of the center of pressure (COP) and balance performance is not fully established. The task constraints and the filtering decomposition of the COP could influence this relationship. COP complexity is related to a better balance performance only in low frequencies and midfrequencies of the COP. The different frequencies measure different postural control components. Filtering decomposition should be explored in future studies to address the underlying mechanisms of postural control.

The significant increases in MGIBE risk ranged from 35% to 55%. The significant increases in the risk of MBE and extracraneal bleeding were 33.4% (SD±14.9) and 54.5% (SD±0.7) respectively. CONCLUSION: The overall risk-benefit assessment of ASA prophylaxis in primary prevention suggests that it should not be applied in people with DM.

ABSTRACT

The aim of this study was to compare the effectiveness of three agents - two antibiotics (amoxicillin and clindamycin) and an antiseptic (chlorhexidine) - to decontaminate bone grafts obtained by low-speed drilling. The study included 248 bone tissue samples harvested from 62 patients by low-speed drilling before dental implant placement. Each of four samples obtained from every patient was dropped, using a sterile instrument, into a sterile tube containing a 500-µl solution of 400µg/mL amoxicillin, 150µg/mL clindamycin, 0.12% chlorhexidine, or physiological saline for 1min. The number of colony-forming units (CFU) was determined at 48h of culture. The use of clindamycin, amoxicillin, or chlorhexidine as decontaminant for 1min significantly reduced the CFU count when compared to physiological saline (control agent). In both anaerobic and CO2-rich atmospheres, significant differences in CFU/mL were found between the control and chlorhexidine groups (P<0.001), control and amoxicillin groups (P<0.001), control and clindamycin groups (P<0.001), chlorhexidine and amoxicillin groups (P<0.0001), and chlorhexidine and clindamycin groups (P<0.0001). In conclusion, clindamycin had the highest decontaminating effect on bone particles obtained by low-speed drilling, followed by chlorhexidine and amoxicillin. Clindamycin may therefore be a valid alternative option for the routine decontamination of intraoral bone grafts.

ABSTRACT

The helminth parasite Fasciola hepatica modulates the host immune response at early stages of infection (Rodríguez et al., PLoS Negl Trop Dis 9:e0004234, 2015; Vukman et al., J Immunol 190:2873-2879, 2013). Nevertheless, little is known about the cell composition of the peritoneal fluid at these early stages of infection.In this chapter, we describe a method to perform peritoneal lavages and to recover peritoneal fluid from sheep experimentally infected and noninfected with F. hepatica at early stages of infection. In addition, with the aim to characterize the peritoneal fluid immune cell phenotype, we describe a procedure to obtain the total leukocyte count, the differential leukocyte count and the preparation and storage of peritoneal fluid smears, together with the application of an immunocytochemical technique and an automatic method to count the immunoreactive cells. Finally, the present protocol describes the evaluation of the gross and the histopathological lesions together with the immunohistochemical analysis of the hepatic tissue.

ABSTRACT

OBJECTIVE: To identify the skills perceived by general practitioners for providing competent care to immigrants MATERIAL AND METHODS: Observational, descriptive and cross-sectional study with data collection using a 21-item questionnaire completed electronically by the general practitioners and validated by the National Validation Commission of SEMERGEN. It was structured with closed-ended, multiple-choice test questions, including variables related to the doctor and variables related to the immigrant patient. The level of professional competence was assessed using a 1 to 10 Likert scale. RESULTS: A total 610 family physicians with a mean age of 47.5±12.3 years responded and 64.1% were women. Of these, 112 (18.4%) were residents. The response rate was 4.9%. A large majority (72.6%) had not taken part in continuing education courses on caring for immigrants in the last 5years. Participants reported difficulties in the clinic: 73% of the cases with the language, 38.7% with the allotted time, and 32.3% due to knowledge of the culture. Most (96.9%) of patients attended the clinic due to a common illness. The cause in 14.4% was related to the migratory process (infectious disease acquired in the country of origin), and in 26.4% with the health conditions in the host country (lack of stable housing, overcrowding, and conditions of work). The perceived level of competence was 6.2±1.9. CONCLUSIONS: The competence perceived by general practitioners in providing care to immigrants is moderate. The most important barriers for these professionals are ignorance of the language, lack of time allocated for consultation, and ignorance of the patient's culture.

ABSTRACT

Cylindrospermopsin (CYN) is a cyanotoxicant which occurrence is increasing due to climate change. Cylindrospermopsin is able to exert damage in the organism at several levels, among them, in the nervous system. Moreover, it is important to take into account that it is not usually present isolated in nature, but in combination with some other pollutants, being the case of the pesticide chlorpyrifos (CPF). Thus, the aim of the present work was to assess the effects of the interaction of CYN in combination with CPF in the human neuroblastoma cell line SH-SY5Y by evaluating cytotoxicity and mechanistic endpoints. The mixtures 0.25 + 21, 0.5 + 42, 1 + 84 µg/mL of CYN + CPF based on cytotoxicity results, were evaluated, and the isobologram method detected an antagonistic effect after 24 and 48 h of exposure. Moreover, although no alterations of reactive oxygen species were detected, a significant decrease of glutathione levels was observed after exposure to both, CPF alone and the combination, at all the concentrations and times of exposure assayed. In addition, CYN + CPF caused a marked decrease in the acetylcholinesterase activity, providing similar values to CPF alone. However, these effects were less severe than expected. All these findings, together with the morphological study results, point out that it is important to take into account the interaction of CYN with other pollutants. Further research is required to contribute to the risk assessment of CYN and other contaminants considering more realistic exposure scenarios.

ABSTRACT

OBJECTIVE: To determine the prevalence of hypotension and associated factors in hypertensive patients treated in the Primary Care setting. MATERIALS AND METHODS: A cross-sectional, descriptive, and multicentre study was conducted with a total of 2635 general practitioners consecutively including 12,961 hypertensive patients treated in a Primary Care setting in Spain. An analysis was performed on the variables of age, gender, weight, height, body mass index, waist circumference, cardiovascular risk factors (diabetes, dyslipidaemia, smoking, obesity, sedentary lifestyle), fasting plasma glucose, complete lipid profile, as well as the presence of target organ damage (left ventricular hypertrophy, microalbuminuria, carotid atherosclerosis) and associated clinical conditions. Hypotension was defined as a systolic blood pressure less than 110mmHg or a diastolic blood pressure less than 70mmHg. A multivariate analysis was performed to determine the variables associated with the presence of hypotension. RESULTS: The mean age was 66.2 years, and 51.7% of patients were women. The mean time of onset of hypertension was 9.1 years. A total of 13.1% of patients (95% confidence interval 12.4-13.6%) had hypotension, 95% of whom had low diastolic blood pressure. The prevalence of hypotension was higher in elderly patients (25.7%) and in those individuals with coronary heart disease (22.6%). The variables associated with the presence of hypotension included a history of cardiovascular disease, being treated with at least 3 antihypertensive drugs, diabetes, and age. CONCLUSIONS: One out of 4-5 elderly patients, or those with cardiovascular disease, had hypotension. General practitioners should identify these patients in order to determine the causes and adjust treatment to avoid complications.

ABSTRACT

Oligosaccharides are gaining importance because of their beneficial properties in human health. They normally appear in natural and synthetic products as complex mixtures of different monomeric units, glycosidic linkages and degrees of polymerization, being disaccharides and trisaccharides usually the most abundant ones. Although liquid chromatography-mass spectrometry is a useful technique for oligosaccharides analysis, the similarity of their structures makes difficult their characterization. Moreover, there is still scarce information about the relationship between carbohydrate chemical structure, mass spectra and chromatographic data. Then, in this work, chromatographic parameters for 23 disaccharides with different linkages and monomeric units (glucose, galactose, mannose and fructose) were determined using porous graphitized and hydrophilic interaction liquid chromatography columns. Moreover, diagnostic ions of these disaccharides obtained by tandem mass spectra (MS2) were established by stepwise linear discriminant analysis. The relationship between carbohydrate chemical structure and their chromatographic retention data and characteristic ions obtained by multiple-stage mass spectrometry (MSn) was successful in establishing some specific criteria that allowed the characterization of trisaccharides with different structural features.
