Temperature dependence of acoustic parameters in pure and blended edible oils: Implications for characterization and authentication.

This research investigates the temperature-dependent variation of diverse acoustic parameters in samples of edible oils. It further supplements previous studies on the effectiveness of non-destructive ultrasonic inspection in the authentication of edible oils. The oils under examination consist of pure samples of olive, sunflower, and corn oils, as well as variable mixtures ranging from 20 % to 80 % of the more expensive one (olive oil) with the other two, simulating a hypothetical adulteration scenario. The studied acoustic parameters are related to the velocity, attenuation, and frequency components present in 2.25 MHz ultrasonic waves propagating through the oil samples within a temperature range of 24 °C to 34 °C. The results confirm the suitability of non-destructive ultrasonic inspection in evaluating and detecting the adulteration of olive oil with economically inferior oils such as sunflower and corn. Additionally, this study provides added value by laying the groundwork for a non-destructive and innovative determination of the fatty acid profile of an edible oil based on the evolution of the aforementioned ultrasonic parameters with temperature. The findings hold potential for enhancing the authenticity assessment and quality control of edible oils in the food industry.

Authentication of pure and adulterated edible oils using non-destructive ultrasound.

At present, the quality of edible oil is evaluated using traditional analysis techniques that are generally destructive. Therefore, efforts are being made to find alternative methods with non-destructive techniques such as Ultrasound. This work aims to confirm the feasibility of non-destructive ultrasonic inspection to characterise and detect fraudulent practices in olive oil due to adulteration with two other edible vegetable oils (sunflower and corn). For this purpose, pulsed ultrasonic signals with a frequency of 2.25 MHz have been used. The samples of pure olive oil were adulterated with the other two in variable percentages between 20% and 80%. Moreover, the viscosity and density values were measured. Both these physicochemical and acoustic parameters were obtained at 24 °C and 30 °C and linearly correlated with each other. The results indicate the sensitivity of the method at all levels of adulteration studied. The responses obtained through the parameters related to the components of velocity, attenuation, and frequency of the ultrasonic waves are complementary to each other. This allows concluding that the classification of pure and adulterated oil samples is possible through non-destructive ultrasonic inspection.

Interactions listed in the Paxlovid fact sheet, classified according to risks, pharmacological groups, and consequences.

Paxlovid (nirmatrelvir plus ritonavir) is a new oral antiviral therapeutic for the treatment and post-exposure prophylaxis of COVID-19. Nirmatrelvir is an inhibitor of SARS-CoV-2 main protease, while ritonavir is used as a CYP3A inhibitor in low doses to slow the metabolism of nirmatrelvir, thus enhancing their therapeutic effect. The isoenzyme CYP3A4 is responsible for at least part of the oxidative metabolism of approximately 60% of available medications and ritonavir is therefore a significant source of drug interactions. We describe here the drugs that are contraindicated or should be used with or without precautions when Paxlovid (nirmaltrevir plus ritonavir) should be administered according to each fact sheet in force at the Spanish Agency for Medicines and Health Products.

Mastitis granulomatosa idiopática complicada con absceso de mama producido por Gordonia sputi, caso clínico / Idiopathic granulomatous mastitis complicated with a breast abscess caused by Gornodia sputi, a case report

La mastitis granulomatosa idiopática es una entidad rara, benigna y crónica de causa desconocida que afecta a la mama. Es un diagnóstico de exclusión. Se deben descartar, entre otras etiologías, la tuberculosis, las infecciones, la sarcoidosis y otras enfermedades autoinmunes, como la arteritis de células gigantes. Los principales retos que plantea esta entidad son su diagnóstico diferencial con enfermedad maligna y su tratamiento. La afectación mamaria es anecdótica y ha sido solo reportada en relación con prótesis mamarias. Presentamos el caso de una paciente diagnosticada de mastitis granulomatosa idiopática complicada con un absceso de mama por Gordonia sputi.

Idiopathic granulomatous mastitis is a rare, benign, chronic entity of unknown cause affecting the breast. It is a diagnosis of exclusion. Among other aetiologies, tuberculosis, infections, sarcoidosis, and other autoimmune diseases such as giant cell arteritis must be ruled out. The main challenges posed by this entity are its differential diagnosis with malignant pathology and its treatment.Gordonia spp. are a group of emerging pathogens that are mainly associated with infections associated with medical devices, mainly catheters. Breast involvement is anecdotal and has only been reported in relation to breast prostheses.We present the case of a patient diagnosed with idiopathic granulomatous mastitis complicated with a breast abscess due to Gordonia sputi.

New findings of edible oil characterization by ultrasonic parameters.

The basic objective of the study was to confirm the usefulness of non-destructive ultrasonic testing in evaluating different edible oil samples. The experimental study was carried out for three types of edible oils (olive, sunflower, and corn) in which a 1.0 MHz ultrasound transducer was immersed. Density and viscosity values of the samples were determined simultaneously with the ultrasound tests. By themselves, ultrasound inspection, density, and viscosity, were able to characterize and distinguish each type from the others, but only the ultrasound inspection has a non-destructive nature. Moreover, significant correlations among density and viscosity with the acoustic parameters were found. The results postulate that ultrasound inspection is a fast and non-destructive tool to characterize and discriminate different types of edible oils.

Differences between diabetic and non-diabetic patients with community-acquired pneumonia in primary care in Spain.

BACKGROUND: Diabetes is one of the underlying risk factors for developing community-acquired pneumonia (CAP). The high prevalence of diabetes among population and the rising incidence of this illness, converts it as an important disease to better control and manage, to prevent its secondary consequences as CAP. The objective of this research is to describe the characteristics of the patients with diabetes and the differences with the no diabetes who have had an episode of CAP in the context of the primary care field. METHODS: A retrospective, observational study in adult patients (> 18 years-old) who suffer from CAP and attended at primary care in Spain between 2009 and 2013 was developed using the Computerized Database for Pharmacoepidemiological Studies in Primary Care (BIFAP). We carried out a descriptive analysis of the first episodes of CAP, in patients with or without diabetes as comorbidity. Other morbidity (CVA, Anaemia, Arthritis, Asthma, Heart disease, Dementia, Depression, Dysphagia, Multiple sclerosis, Epilepsy, COPD, Liver disease, Arthrosis, Parkinson's disease, Kidney disease, HIV) and life-style factors were also included in the study. RESULTS: A total of 51,185 patients were included in the study as they suffer from the first episode of CAP. Of these, 8012 had diabetes as comorbidity. There were differences between sex and age in patients with diabetes. Patients without diabetes were younger, and had less comorbidities including those related to lifestyles such as smoking, alcoholism, social and dental problems than patients with diabetes. CONCLUSIONS: Patients who developed an episode of CAP with diabetes have more risk factors which could be reduced with an appropriate intervention, including vaccination to prevent successive CAP episodes and hospitalization. The burden of associated factors in these patients can produce an accumulation of risk. Health care professional should know this for treating and control these patients in order to avoid complications. Diabetes and those other risk factors associated could be reduced with an appropriate intervention, including vaccination to prevent the first and successive CAP episodes and the subsequent hospitalization in severe cases.

[Consensus document on pneumococcal vaccination in adults at risk by age and underlying clinical conditions. 2017 Update]. / Consenso sobre la vacunación anti-neumocócica en el adulto por riesgo de edad y patología de base. Actualización 2017.

Invasive pneumococcal disease (IPD) and pneumococcal pneumonia (PP) represent an important health problem among aging adults and those with certain underlying pathologies and some diseases, especially immunosuppressed and some immunocompetent subjects, who are more susceptible to infections and present greater severity and worse evolution. Among the strategies to prevent IPD and PP, vaccination has its place, although vaccination coverage in this group is lower than desirable. Nowadays, there are 2 vaccines available for adults. Polysacharide vaccine (PPV23), used in patients aged 2 and older since decades ago, includes a greater number of serotypes (23), but it does not generate immune memory, antibody levels decrease with time, causes an immune tolerance phenomenon, and have no effect on nasopharyngeal colonization. PCV13 can be used from children 6 weeks of age to elderly and generates an immune response more powerful than PPV23 against most of the 13 serotypes included in it. In the year 2013 the 16 most directly related to groups of risk of presenting IPD publised a series of vaccine recommendations based on scientific evidence regarding anti-pneumococcal vaccination in adults with underlying pathologies and special conditions. A commitment was made about updating it if new scientific evidence became available. We present an exhaustive revised document focusing mainly in recommendation by age in which some more Scientific Societies have been involved.

Incidence and risk factor prevalence of community-acquired pneumonia in adults in primary care in Spain (NEUMO-ES-RISK project).

BACKGROUND: Community-acquired pneumonia (CAP) is a major cause of morbidity and mortality in adults even in developed countries. Several lifestyle factors and comorbidities have been linked to an increased risk, although their prevalence has not been well documented in the primary care setting. The aim of this study is to assess the incidence, risk factor and comorbid conditions distribution of CAP in adults in primary care in Spain. METHODS: Retrospective observational study in adults (>18 years-old) with CAP diagnosed and attended at primary care in Spain between 2009 and 2013, using the Computerized Database for Pharmacoepidemiological Studies in Primary Care (BIFAP). RESULTS: Twenty-eight thousand four hundred thirteen patient records were retrieved and analyzed. Mean age (standard deviation): 60.5 (20.3) years, 51.7 % males. Global incidence of CAP in adults was estimated at 4.63 per 1000 persons/year. CAP incidence increased progressively with age, ranging from a 1.98 at 18-20 years of age to 23.74 in patients over 90 years of age. According to sex, global CAP incidence was slightly higher in males (5.04) than females (4.26); CAP incidence from 18 to 65 year-olds up was comparable between males (range: 2.18-5.75) and females (range: 1.47-5.21), whereas from 65 years of age, CAP incidence was noticeable higher in males (range: 7.06-36.93) than in females (range: 5.43-19.62). Average prevalence of risk factors was 71.3 %, which increased with age, doubling the risk in males by the age of 75 (females 20 % vs males 40 %). From 55 years of age, at least one risk factor was identified in 85.7 % of cases: one risk factor (23.8 %), two risk factors (23.4 %), three or more risk factors (38.5 %). Major risk factors were: metabolic disease (27.4 %), cardiovascular disease (17.8 %) and diabetes (15.5 %). CONCLUSIONS: The annual incidence of CAP in primary care adults in Spain is high, comparable between males and females up to 65 years of age, but clearly increasing in males from that age. CAP risk increases with age and doubles in males older than 75 years. The majority of CAP cases in patients over 55 years of age is associated to at least one risk factor. The main risk factors associated were metabolic disease, cardiovascular disease, and diabetes.

New contributions to granite characterization by ultrasonic testing.

Ultrasound evaluation permits the state of rocks to be determined quickly and cheaply, satisfying the demands faced by today's producers of ornamental stone, such as environmental sustainability, durability and safety of use. The basic objective of the present work is to analyse and develop the usefulness of ultrasound testing in estimating the physico-mechanical properties of granite. Various parameters related to Fast Fourier Transform (FFTs) and attenuation have been extracted from some of the studies conducted (parameters which have not previously been considered in work on this topic, unlike the ultrasonic pulse velocity). The experimental study was carried out on cubic specimens of 30 cm edges using longitudinal and shear wave transducers and equipment which extended the normally used natural resonance frequency range up to 500 kHz. Additionally, a validation study of the laboratory data has been conducted and some methodological improvements have been implemented. The main contribution of the work is the analysis of linear statistical correlations between the aforementioned new ultrasound parameters and physico-mechanical properties of the granites that had not previously been studied, i.e., resistance to salt crystallization and breaking load for anchors. Being properties that directly affect the durability and safety of use of granites, these correlations consolidate ultrasonics as a nondestructive method well suited to this type of material.

Exposure to high-frequency electromagnetic fields (100 kHz-2 GHz) in Extremadura (Spain).

The last decade has seen a rapid increase in people's exposure to electromagnetic fields. This paper reports the measurements of radiofrequency (RF) total power densities and power density spectra in 35 towns of the region of Extremadura, Spain. The spectra were taken with three antennas covering frequencies from 100 kHz to 2.2 GHz. This frequency range includes AM/FM radio broadcasting, television, and cellular telephone signals. The power density data and transmitting antenna locations were stored in a geographic information system (GIS) as an aid in analyzing and interpreting the results. The results showed the power density levels to be below the reference level guidelines for human exposure and that the power densities are different for different frequency ranges and different size categories of towns.

[Early onset schizophrenia and partial agenesis of corpus callosum]. / Schizophrénie à début précoce et agénésie partielle du corps calleux.

We report a case of schizophrenia with partial agenesis of the corpus callosum in a 14-year-old girl. Diagnosis of schizophrenia was confirmed in the longitudinal follow-up and partial agenesis of the corpus callosum was found on brain MRI at the prodromal stage of disease. The prodromal symptom was progressive deterioration of social and academic adjustment in a context of non-specified psychotic disorder in the father. We found no abnormality in the development but a history of seizures that did not require specific treatment. Follow-up at 8 months showed an increase in negative symptoms and the onset of delusional symptoms and disorganization leading to the prescription of antipsychotic treatment. A review of the literature shows that agenesis of corpus callosum is the most reliable brain morphology abnormality in schizophrenia and is related to the neurodevelopmental and abnormal brain connectivity hypothesis in schizophrenia. Although this abnormality may be a marker of disease severity, our case report highlights the lack of longitudinal follow-up to allow the characterization of a specific outcome pattern of schizophrenic adolescents with partial agenesis of the corpus callosum.

Validation of a professionals' satisfaction questionnaire with electronic medical records (PSQ-EMR) in psychiatry.

BACKGROUND: Electronic medical records (EMR) are currently being implemented in psychiatric hospitals throughout Europe. The perceptions of health care professionals can contribute important information that may predict their acceptance of and desired mode of use for EMR, thus guiding EMR implementation. AIMS: To develop a self-administered instrument designed to assess health care professionals' satisfaction regarding EMR in a psychiatric hospital, based only on the professional point of view, according to the psychometric standards. METHODS: The development was supervised by a steering committee and undertaken by three standard steps. Item generation was derived from 115 face-to-face interviews with health care professionals in a French, public, psychiatric hospital. The item-reduction process resulted in a 25-item questionnaire. The validation process was based on construct validity, reliability and some aspects of external validity. RESULTS: The final version of the questionnaire contained 25 items that described five dimensions, leading to a global score. The factor structure accounted for 72% of the total variance. Internal consistency was satisfactory (item-internal consistency over 0.40 and Cronbach's alpha coefficients ranged from 0.86 to 0.95). The scalability was satisfactory with INFIT statistics inside an acceptable range. Scores of dimensions were strongly positively correlated with visual analogue scale scores (all p < 0.001). External validity showed statistical associations between scores and age, gender, seniority in psychiatry and ward type. Participation rate was 66%. CONCLUSION: The availability of a reliable and valid questionnaire (professionals' satisfaction questionnaire with electronic medical records [PSQ-EMR]) concerning health care professionals' satisfaction regarding EMR in psychiatry, exclusively generated from interviews with health care professionals, enables legitimate feedback to be incorporated into EMR implementation in order to formulate a high-quality health care.

Implicit theories of intelligence and IQ test performance in adolescents with Generalized Anxiety Disorder.

During the past decade, several studies have reported positive effects of cognitive-behavioral therapy (CBT) in the treatment of children and adolescents with mental disorders. One of the most important CBT interventions is to teach children and adolescents to challenge negative thoughts that lead to maladjusted behaviors. Based on the implicit theories of intelligence framework, the main purpose of this study was to test whether an incremental theory manipulation could be used to affect IQ test performance in adolescents with Generalized Anxiety Disorder (GAD). Results showed that patients demonstrated enhanced IQ performance and experienced less state anxiety when they were exposed to an incremental theory of intelligence manipulation. Our findings suggest that incremental theory manipulation provides a useful cognitive strategy for addressing school-related anxiety in adolescents with mental disorders such as GAD.
