Enhancing the Performance of BaxMnO3 (x = 1, 0.9, 0.8 and 0.7) Perovskites as Catalysts for CO Oxidation by Decreasing the Ba Content.

Mixed oxides featuring perovskite-type structures (ABO3) offer promising catalytic properties for applications focused on the control of atmospheric pollution. In this work, a series of BaxMnO3 (x = 1, 0.9, 0.8 and 0.7) samples have been synthesized, characterized and tested as catalysts for CO oxidation reaction in conditions close to that found in the exhausts of last-generation automotive internal combustion engines. All samples were observed to be active as catalysts for CO oxidation during CO-TPRe tests, with Ba0.7MnO3 (B0.7M) being the most active one, as it presents the highest amount of oxygen vacancies (which act as active sites for CO oxidation) and Mn (IV), which features the highest levels of reducibility and the best redox properties. B0.7M has also showcased a high stability during reactions at 300 °C, even though a slightly lower CO conversion is achieved during the second consecutive reaction cycle. This performance appears to be related to the decrease in the Mn (IV)/Mn (III) ratio.

Three-year analysis of results, safety and progression in patients with open-angle glaucoma or ocular hypertension, undertaking trabecular microsurgery.

AIM: To evaluate the efficacy, safety, structural and functional progression following the insertion of iStent inject ® implants in patients with open-angle glaucoma or ocular hypertension at a tertiary-level hospital. MATERIALS AND METHODS: A retrospective study included 98 eyes (57 males and 41 females) with open-angle glaucoma or ocular hypertension, which underwent iStent inject W® implantation (Glaukos, Corporation, CA) between December 2018 and December 2022. Differences in intraocular pressure (IOP), the number of hypotensive eye drops used, and structural and functional tests were assessed between preoperative values and subsequent reviews during a follow-up period of one (n = 98), two (n = 55), and three years (n = 15) after surgery. RESULTS: Among the 98 eyes studied, 85% were diagnosed with open-angle glaucoma (50% mild, 32% moderate, and 18% severe) and 15% with ocular hypertension. There was a statistically significant reduction in IOP compared to preoperative values for all visits except the 1-month (p = 0.36) and 3-year (p = 0.39) visits. Visual acuity increased from 0.39 ±â€¯0.25 to 0.72 ±â€¯0.24 (p < 0.01), considering that a significant portion of the interventions included cataract surgery. Before surgery, 66% of the sample used 2 or more hypotensive medications. Post-surgery, the number of hypotensive medications decreased (from 1.88 ±â€¯0.84 to 0.21 ±â€¯0.59 at 3 years) (p < 0.01), with an 88.9% reduction in the number of medications over three years. After surgery, 75% of cases did not require any medication. Regarding structural and functional tests, thickness of retinal nerve fiber layers (RNFL (p = 0.35), excavation / papilla ratio E/P (p = 0.31), visual function index (VFI (p = 0.06), and deviation mean (MD (p = 0.06) showed no statistically significant differences post-intervention. However, standard deviation of the pattern (DSM) did exhibit differences, decreasing from 5.46 ±â€¯4.03 dB to 5.34 ±â€¯3.48 dB (p = 0.02). CONCLUSION: The results of this study suggest that the iStent inject W® technique constitutes an effective and safe option for tension control and glaucoma treatment.

Update in imaging tests used for the localization of parathyroid pathology.

Preoperative localization of parathyroid pathology, generally a parathyroid adenoma, can be difficult in some cases due to the anatomical variants that these glands present. The objective of this review is to analyse the different imaging techniques used for preoperative localization of parathyroid pathology (scintigraphy, ultrasound, CT, MRI and PET). There is great variability between the different tests for the preoperative localization of parathyroid pathology. The importance of knowing the different diagnostic options lies in the need to choose the most suitable test at each moment and for each patient for an adequate management of primary hyperparathyroidism (PHP) with surgical criteria.

Adverse cardiovascular, obstetric and perinatal events during pregnancy and puerperium in patients with heart disease.

BACKGROUND AND OBJECTIVES: cardiovascular changes during pregnancy carry greater risk in heart disease. We analyze cardiovascular, obstetric and perinatal adverse effects associated with congenital and acquired heart disease during pregnancy and postpartum. MATERIALS AND METHODS: Cross-sectional and retrospective study, which included the 2017-2023 registry of pregnant or postpartum patients hospitalised with diagnosis of congenital or acquired heart disease. Adverse events (heart failure, stroke, acute pulmonary edema, maternal death, obstetric haemorrhage, prematurity and perinatal death) were compared with the clinical variables and the implemented treatment. RESULTS: 112 patients with a median age of 28 years (range 15-44) were included. Short circuits predominated 28 (25%). Thirty-six patients (32%) were classified in class IV of the modified WHO scale for maternal cardiovascular risk. Heart failure occurred in 39 (34.8%), acute lung edema 12 (10.7%), stroke 2 (1.8%), maternal death 5 (4.5%), obstetric haemorrhage 4 (3.6%), prematurity 50 (44.5%) and perinatal death 6 (5.4%). Shunts were associated with prematurity (adjusted odds ratio 4; 95% CI: 1.5-10, p = 0.006). Peripartum cardiomyopathy represented higher risk of pulmonary edema (adjusted OR 34; 95% CI: 6-194, p = 0.001) and heart failure (adjusted OR 16; 95% CI: 3-84, p = 0.001). An increased risk of obstetric haemorrhage was observed in patients with prosthetic valves (adjusted OR 30; 95% CI: 1.5-616, p = 0.025) and with the use of acetylsalicylic acid (adjusted OR 14; 95% CI: 1.2-16, p = 0.030). Furthermore, the latter was associated with perinatal death (adjusted OR 9; 95% CI: 1.4-68, p = 0.021). CONCLUSIONS: severe complications were found during pregnancy and postpartum in patients with heart disease, which is why preconception evaluation and close surveillance are vital.

Prognostic value of brain perfusion by MRI in the initial study of high grade gliomas.

OBJECTIVES: To evaluate if the tumour perfusion at the initial MRI scan is a marker of prognosis for survival in patients diagnosed with High Grade Gliomas (HGG). To analyse the risk factors which influence on the mortality from HGG to quantify the overall survival to be expected in patients. PATIENTS AND METHODS: The patients diagnosed with HGG through a MRI scan in a third-level hospital between 2017 and 2019 were selected. Clinical and tumour variables were collected. The survival analysis was used to determine the association between the tumour perfusion and the survival time. The relation between the collected variables and the survival period was assessed through Wald's statistical method, measuring the relationship via Cox's regression model. Finally, the type of relationship that exists between the tumour perfusion and the survival was analysed through the Lineal Regression method.Those statistical analysis were carried out using the software SPSS v.17. RESULTS: 38 patients were included (average age: 61.1 years old). The general average survival period was 20.6 months. A relationship between the tumour perfusion at the MRI scan and the overall survival has been identified, in detail, a group with intratumor values of relative cerebral blood volume (rCBV)>3.0 has shown a significant decline in the average survival period with regard to the average survival period of the group with values <3.0 (14.6 months vs. 22.8 months, p = 0.046). It has also been proved that variables like Karnofsky's scale and the response time since the intervention significantly influence on the survival period. CONCLUSIONS: It has become evident that the tumour perfusion via MRI scan has a prognostic value in the initial analysis of HGG. The average survival period of patients with rCBV less than or equal to 3.0 is significantly higher than those patients whose values are higher, which allows to be more precise with the prognosis of each patient.

Epidemiology of ataxia and hereditary spastic paraplegia in Spain: A cross-sectional study.

INTRODUCTION: Ataxia and hereditary spastic paraplegia are rare neurodegenerative syndromes. We aimed to determine the prevalence of these disorders in Spain in 2019. PATIENTS AND METHODS: We conducted a cross-sectional, multicentre, retrospective, descriptive study of patients with ataxia and hereditary spastic paraplegia in Spain between March 2018 and December 2019. RESULTS: We gathered data from a total of 1933 patients from 11 autonomous communities, provided by 47 neurologists or geneticists. Mean (SD) age in our sample was 53.64 (20.51) years; 938 patients were men (48.5%) and 995 were women (51.5%). The genetic defect was unidentified in 920 patients (47.6%). A total of 1371 patients (70.9%) had ataxia and 562 (29.1%) had hereditary spastic paraplegia. Prevalence rates for ataxia and hereditary spastic paraplegia were estimated at 5.48 and 2.24 cases per 100 000 population, respectively. The most frequent type of dominant ataxia in our sample was SCA3, and the most frequent recessive ataxia was Friedreich ataxia. The most frequent type of dominant hereditary spastic paraplegia in our sample was SPG4, and the most frequent recessive type was SPG7. CONCLUSIONS: In our sample, the estimated prevalence of ataxia and hereditary spastic paraplegia was 7.73 cases per 100 000 population. This rate is similar to those reported for other countries. Genetic diagnosis was not available in 47.6% of cases. Despite these limitations, our study provides useful data for estimating the necessary healthcare resources for these patients, raising awareness of these diseases, determining the most frequent causal mutations for local screening programmes, and promoting the development of clinical trials.

Use of healthcare REsources and associated COsts in controlled versus uncontrolled carcinoid SYndrome in patients with neuroendocrine tumours: the RECOSY study.

PURPOSE: To report healthcare resource use and associated costs in controlled versus uncontrolled carcinoid syndrome (CS) in patients with neuroendocrine tumours. METHODS: A cross-sectional, non-interventional multicentre study was conducted with retrospective data analysis. Resource use was compared between two patient groups: those with controlled CS (> 12 months with no uncontrolled CS episodes) and uncontrolled CS (< 12 months since last uncontrolled episode). Patients were matched for age, sex, and origin and grade of tumour. When no matching patients were available, data from deceased patients were used. Information on healthcare resource use came from review of medical records, patient history and physician reports. Working capacity was assessed using the Work Productivity and Activity Impairment General Health questionnaire. RESULTS: Twenty-six university hospitals in Spain participated, between July 2017 and April 2018. 137 patients were enrolled; 104 were analysed (2 groups of 52). Patients with uncontrolled CS had 10 times more emergency department (ED) visits (mean 1.0 vs 0.10 visits; P = 0.0167), were more likely to have a hospital admission (40.4% vs 19.2%; P = 0.0116) and had longer hospital stays (mean 7.87 vs 2.10 days; P = 0.0178) than those with controlled CS. This corresponded to higher annual hospitalisation costs (mean €5511.59 vs €1457.22; P = 0.028) and ED costs (€161.25 vs €14.85; P = 0.0236). The mean annual total healthcare costs were 60.0% higher in patients with uncontrolled than controlled CS (P = NS). CONCLUSION: This study quantifies higher health resource use, and higher hospitalisation and ED costs in patients with uncontrolled CS. Better control of CS may result 3in lower medical costs.

Use of CT-scan in pediatric patients with thoraco-abdominal trauma: experience at a latin-american trauma facility. / Uso de la TAC en pacientes pediátricos con trauma toraco-abdominal: experiencia de un centro de trauma latinoamericano.

INTRODUCTION: CT-scan is the method of choice for major trauma assessment. However, it significantly increases radiation exposure in the pediatric population. The objective of this study was to analyze differences in clinical outcomes according to the preoperative use of CT-scan. MATERIALS AND METHODS: A retrospective observational study of pediatric patients admitted for trauma and requiring surgery was carried out. Patients were classified according to the previous use of CT-scan. ICU stay, re-admissions, and deaths were assessed. RESULTS: From 2011 to 2017, 737 patients under 18 years of age with external lesions were treated, 174 of whom required surgery. 48 patients (27.6%) underwent CT-scan prior to the procedure (Group 1), while the remaining 126 patients (72.4%) were directly scheduled for surgery (Group 2). Penetrating trauma occurred in 81% of patients, the proportion being significantly higher in Group 2 (p= 0.001). Median age was 15 years (interquartile range: 12-17), with no differences between groups. No significant differences were found in terms of hemodynamic instability at admission between groups (p= 0.596). At surgery, 3 out of 48 patients (6.3%) had no evident lesion. No significant differences were found in terms of re-admissions (p= 0.476), mortality (0.994), and ICU stay (0.466). CONCLUSION: The use of CT-scan as a diagnostic tool in pediatric trauma does not reduce mortality, ICU stay, or number of re-admissions. The use of tools such as ultrasound examination and simple X-ray should be protocolized to avoid unnecessary exposure to higher radiation doses. Prospective studies confirming this hypothesis are required.

INTRODUCCION: La tomografía axial computarizada (TAC) es el método de elección en la evaluación del trauma mayor, sin embargo, aumenta significativamente la exposición a radiación en la población pediátrica. El objetivo de este estudio es determinar diferencias en los desenlaces clínicos de acuerdo con el uso preoperatorio de la TAC. METODOS: Estudio observacional retrospectivo. Se incluyeron pacientes pediátricos ingresados por trauma que necesitaron manejo quirúrgico, y se clasificaron de acuerdo con el uso previo de TAC. Se evaluó tiempo en Unidad de Cuidados Intensivos (UCI), readmisiones, y muerte. RESULTADOS: Durante 2011 a 2017, 737 pacientes menores de 18 años consultaron por lesiones de causa externa, 174 requirieron intervención quirúrgica. A 48 (27,6%) se les realizó TAC previo al manejo quirúrgico (Grupo 1); los restantes 126 pacientes (72,4%) fueron llevados directamente a cirugía (Grupo 2). El trauma penetrante se presentó en un 81% de los pacientes, siendo significativamente mayor en el grupo 2 (p= 0,001). La mediana de edad fue 15 años (rango intercuartílico 12-17) sin diferencia entre los grupos. No hubo diferencias significativas en inestabilidad hemodinámica al ingreso entre los grupos (p= 0,596). Al momento de la cirugía, tres de 48 pacientes (6,3%) no presentaron ninguna lesión evidente. No hubo diferencias significativas en las readmisiones (p= 0,476), la mortalidad (0.994) y estancia en UCI (0,466). CONCLUSION: El uso de TAC como herramienta diagnóstica en trauma pediátrico no disminuye la mortalidad, días de estancia en UCI, ni el número de readmisiones. Debe protocolizarse el uso de herramientas como la ecografía y radiografía simple para evitar exposición innecesaria a dosis más altas de radiación. Se requieren estudios prospectivos que confirmen esta hipótesis.

Sistema penitenciario y vejez: aportes de la evaluación neuropsicológica forense / Penitentiary System and old age: contributions of the forensic neuropsychological evaluation

Resumen Introducción: El envejecimiento poblacional ha impulsado a que su abordaje se convierta en un tema prioritario a nivel mundial, sobre la cual aún existen mitos y discriminación, siendo las personas adultas mayores en privación de libertad en un sistema penitenciario, una población con mayores riesgos de exclusión y que cuentan con características neuropsicológicas que ameritan su atención. Por lo tanto, se realizó en Costa Rica un primer abordaje en el Centro de Atención Institucional Adulto Mayor desde la neuropsicología forense, para mejorar los protocolos disponibles de evaluación de la población adulta mayor. Procedimiento: Se llevó a cabo un trabajo final de graduación en formato de práctica dirigida durante 858 horas tanto de forma presencial como a distancia, en el período de abril del 2017 a abril del 2018, participando de los procesos de evaluación neuropsicológica forense, elaboración de un protocolo de evaluación neuropsicológica forense y participación en procesos psicoeducativos sobre consumo de sustancias y violencia sexual. Resultados: En total se atendieron 40 personas hombres, entre 58 y 85 años de edad. Con variables sociodemográficas y de salud como una baja escolaridad (45%), con antecedentes de trauma craneoencefálico (67%) y en su mayoría cometieron abuso sexual (55%). Se elaboró un protocolo de evaluación neuropsicológica que incluye un módulo de entrevista y observación, evaluación del estado de ánimo y evaluación del funcionamiento cognitivo.

Abstract Introduction: Population ageing has become a priority between the attention and care systems but still deals with myths and discrimination, being the older adults incarcerated in the prison system a population with a greater risk of exclusion and that have neuropsychological characteristics that need attention. Therefore, a first approach was carried out in Costa Rica in the Institutional Adult Care Center from the forensic neuropsychology, to improve the available protocols for the evaluation of the older adult population. Method: A final graduation work was carried out in a guided practice format for 858 hours both in person and remotely, in the period from April 2017 to April 2018, participating in the processes of forensic neuropsychological evaluation, preparation of a protocol of forensic neuropsychological evaluation and participation in psychoeducational processes on substance use and sexual violence. Results: In total 40 male people, between 58 and 85 years of age, were attended. With sociodemographic and health variables such as low schooling (45%), with a history of cranioencephalic trauma (67%) and most of them committed sexual abuse (55%). A neuropsychological evaluation protocol was elaborated that includes an interview and observation module, evaluation of mood and evaluation of cognitive functioning module.

Substance use disorders in patients with intellectual disability admitted to psychiatric hospitalisation.

BACKGROUND: Few studies have looked at the prevalence of substance use disorders (SUD) in people with intellectual disability (ID). The results range between 1% and 6.4% and go up to 20% in people with ID and psychiatric disorders, probably underestimating real prevalence due to several limitations in these studies. ID confers risk for the development of SUD, which in turn will involve negative psychosocial and clinical consequences. We aimed to study the prevalence of SUD in a sample of patients with ID admitted to a brief hospitalisation psychiatric unit, describing them by type and severity and analysing their relationship with clinical, prognostic and access to treatment variables. METHODS: We undertook a descriptive, cross-sectional and retrospective study by means of a review of clinical histories of all patients with a diagnosis of ID, admitted in a period of 10 years. RESULTS: Among the final sample of patients included, 52.3% had a mild ID, 40.9% an unspecified ID, 3.4% a moderate ID and another 3.4% a severe ID. More than one third of the sample met criteria for a SUD. The main SUD was cannabis use disorder (25%), followed by alcohol use disorder (22.7%) and cocaine use disorder (13.6%). The use of more than one substance was the most frequent pattern. Cannabis use disorder and cocaine use disorder were overrepresented in the group with mild ID. A greater number of psychiatric admissions was observed for the group with SUD. Specialised mental health services for ID and specialised addiction network facilities were much less involved in the care of these patients that could be expected according to good clinical practice recommendations. CONCLUSIONS: Substance use disorder in patients with ID and mental health disorders admitted to psychiatric hospitalisation are prevalent, which makes this issue an area of interest for future improvements in case identification, proper referring to specialised treatment resources and an increasing research focusing on specific therapeutic approaches.

[Attention deficit hyperactivity disorder in preschool age children. Its epidemiological prevalence in Navarra and La Rioja, Spain]. / Trastorno por deficit de atencion/hiperactividad en niños en edad preescolar. Prevalencia epidemiologica en Navarra y La Rioja, España.

INTRODUCTION: There are few studies about preschool attention deficit hyperactivity disorder (ADHD) prevalence. AIM: To study the prevalence of ADHD in preschoolers using an specific scale (ADHD-RS-IV-P-Es) developed for this age range. SUBJECTS AND METHODS: We evaluated the prevalence of possible ADHD in a representative sample of preschoolers in Navarra and La Rioja, Spain. RESULTS: We find a range of prevalence between 2.5-4.1% depending on the criteria that was used (more or less strict). CONCLUSIONS: There are specific tools that can be use in preschool ADHD study. The prevalence of preschool ADHD in Spain is similar than in other countries. The frequency of symptoms in this age range is similar to the found in school age children.

TITLE: Trastorno por deficit de atencion/hiperactividad en niños en edad preescolar. Prevalencia epidemiologica en Navarra y La Rioja, España.Introduccion. La prevalencia del trastorno por deficit de atencion/hiperactividad (TDAH) esta en constante estudio, y hay pocas publicaciones sobre la prevalencia en niños preescolares. Objetivo. Estudiar la prevalencia de sintomas de TDAH en niños preescolares usando una escala especifica (ADHD Rating Scale-IV, version preescolar, validada para España) desarrollada para esta franja de edad. Sujetos y metodos. Se evalua la prevalencia de posible TDAH en una muestra representativa de preescolares en Navarra y La Rioja usando diferentes puntos de corte. Resultados. Se encuentra un rango de prevalencia de sintomas de TDAH del 2,5-4,1% segun el criterio usado (mas o menos estricto). Conclusiones. Existen herramientas especificas que pueden usarse para evaluar el TDAH en preescolares. La prevalencia de posible TDAH en preescolares en España es similar a la encontrada en otros paises. La frecuencia de sintomas en esta franja de edad no es mas alta que en otras edades, por lo que no es cierto que los sintomas de TDAH sean muy prevalentes en la poblacion general de niños preescolares.

Delta-like protein 1 in the pituitary-adipose axis in the adult male mouse.

With the aim of studying delta-like protein 1 (DLK1) with respect to the relationship between adipocyte leptin and adenohypophyseal hormones, we carried out an immunohistochemical study analysing the presence of receptors for these hormones in the pituitary and adipose cells of male wild-type (WT) mice (Dlk1+/+ ) compared to knockout (KO) mice (Dlk1-/- ). The mRNA expression of these molecules was also determined using the reverse transcriptase-polymerase chain reaction. The results obtained showed that, in WT adipose cells, all of the adenohypophyseal hormone receptors were present, with a higher mRNA expression for growth hormone (GH) receptor and thyroid-stimulating hormone (TSH) receptor. Of the total cells in the anterior pituitary lobe, 17.09±0.9% were leptin receptor (LEPR) immunoreactive (-IR), mainly in GH-IR and prolactin (PRL)-IR cells (41.5±3.8%; 13.5±1.7%, respectively). In Dlk1-/- mice, adipocyte cells showed a significant increase in the TSH receptor mRNA expression level. Moreover, the percentage of LEPR-IR GH cells showed a statistically significant increase compared to controls, from 41.5±3.8% to 53.1±4.0%. By contrast, only 3.0±0.6% of LEP-IR anterior pituitary cells were detected in Dlk1 KO mice, as opposed to 6.8±1.1% observed in WT mice. The results suggest that relationships exist between adipocytes and pituitary GH, PRL and TSH cells, in addition to an influence with respect to the synthesis and release of pituitary leptin, particularly in PRL cells.

Psychomotor development and learning difficulties in preschool children with probable attention deficit hyperactivity disorder: An epidemiological study in Navarre and La Rioja. / Desarrollo psicomotor y dificultades del aprendizaje en preescolares con probable trastorno por déficit de atención e hiperactividad. Estudio epidemiológico en Navarra y La Rioja.

INTRODUCTION: ADHD symptoms begin to appear at preschool age. ADHD may have a significant negative impact on academic performance. In Spain, there are no standardized tools for detecting ADHD at preschool age, nor is there data about the incidence of this disorder. OBJECTIVE: To evaluate developmental factors and learning difficulties associated with probable ADHD and to assess the impact of ADHD in school performance. METHODS: We conducted a population-based study with a stratified multistage proportional cluster sample design. RESULTS: We found significant differences between probable ADHD and parents' perception of difficulties in expressive language, comprehension, and fine motor skills, as well as in emotions, concentration, behaviour, and relationships. Around 34% of preschool children with probable ADHD showed global learning difficulties, mainly in patients with the inattentive type. According to the multivariate analysis, learning difficulties were significantly associated with both delayed psychomotor development during the first 3 years of life (OR: 5.57) as assessed by parents, and probable ADHD (OR: 2.34) CONCLUSIONS: There is a connection between probable ADHD in preschool children and parents' perception of difficulties in several dimensions of development and learning. Early detection of ADHD at preschool ages is necessary to start prompt and effective clinical and educational interventions.

Sequential antimicrobial treatment with linezolid for neurosurgical infections: efficacy, safety and cost study.

BACKGROUND: Evidence for the effectiveness of linezolid in neurosurgical infections (NSIs) is growing. The comfortable oral dosage and tolerance of linezolid opens the possibility for sequential antimicrobial treatment (SAT) in stable patients after a period of intravenous treatment. METHODS: To evaluate the efficacy and safety of SAT with oral linezolid in patients with NSI and to analyse the cost implications, an observational, non-comparative, prospective cohort study was conducted on clinically stable consecutive adult patients at the Neurosurgical Service. Following intravenous treatment, patients were discharged with SAT with oral linezolid. RESULTS: A total of 77 patients were included. The most common NSIs were: 41 surgical wound infections, 20 subdural empyemas, 18 epidural abscesses, and 16 brain abscesses. Forty-four percent of patients presented two or more concomitant NSIs. Aetiological agents commonly isolated were: Propionibacterium acnes (36 %), Staphylococcus aureus (23 %), Staphylococcus epidermidis (21 %) and Streptococcus spp. (13 %). The median duration of the SAT was 15 days (range, 3-42). The SAT was interrupted in five cases due to adverse events. The remainder of the patients were cured at the end of the SAT. A total of 1,163 days of hospitalisation were saved. An overall cost reduction of €516,188 was attributed to the SAT. Eight patients with device infections did not require removal of the device, with an additional cost reduction of €190,595. The mean cost saving per patient was €9,179. CONCLUSIONS: SAT with linezolid was safe and effective for the treatment of NSI. SAT reduces hospitalisation times, which means significant savings of health and economic resources.

Rapid, automated online SPE-LC-QTRAP-MS/MS method for the simultaneous analysis of 14 phthalate metabolites and 5 bisphenol analogues in human urine.

Phthalates and bisphenol A (BPA) have received special attention in recent years due to their frequent use in consumer products and potential for adverse effects on human health. BPA is being replaced with a number of alternatives, including bisphenol S, bisphenol B, bisphenol F and bisphenol AF. These bisphenol analogues have similar potential for adverse health effects, but studies on human exposure are limited. Accurate measurement of multiple contaminants is important for estimating exposure. This paper describes a sensitive and automated method for the simultaneous determination of 14 phthalate metabolites, BPA and four bisphenol analogues in urine using online solid phase extraction coupled with high-performance liquid chromatography/tandem mass spectrometry using a hybrid triple-quadrupole linear ion trap mass spectrometer (LC-QTRAP-MS/MS), requiring very little sample volume (50µL). Quantification was performed under selected reaction monitoring (SRM) mode with negative electrospray ionization. The use of SRM combined with an enhanced product ion scan within the same analysis was examined. Unequivocal identification was provided by the acquisition of three SRM transitions per compound and isotope dilution. The analytical performance of the method was evaluated in synthetic and human urine. Linearity of response over three orders of magnitude was demonstrated for all of the compounds (R(2)>0.99), with method detection limits of 0.01-0.5ng/mL and limits of reporting of 0.07-3.1ng/mL. Accuracy ranged from 93% to 113% and inter- and intra-day precision were <22%. Finally, the validated method has been successfully applied to a cohort of pregnant women to measure biomarker concentrations of phthalates and bisphenols, with median concentrations ranging from 0.3ng/mL (bisphenol S) to 18.5ng/mL (monoethyl phthalate).

[Profile of prescription and adequacy of treatment with non-steroidal anti-inflammatory drugs in diabetic patients]. / Perfil de prescripción y adecuación del tratamiento con antiinflamatorios no esteroideos en el paciente diabético.

OBJECTIVE: The aim of this study was to quantify and describe the prescription profile, as well as to assess the adequacy of treatment with non-steroidal anti-inflammatory drugs (NSAIDs) in the diabetic population of a health district. MATERIAL AND METHODS: This is a descriptive, cross-sectional study aimed at a target population of 2,795 diabetic patients. Data were collected from the computerised clinical records of a sample of 380 individuals. The adequacy of treatment was assessed using the recommendations proposed by the Spanish societies of Rheumatology, Cardiology and Gastroenterology. RESULTS: More than one-quarter (28%) of the diabetic patients received treatment with NSAIDs. The most commonly used ones were ibuprofen, naproxen, and dexketoprofen, with a defined daily dose per 1,000 inhabitants per day of 35.3, 17.2, and 13.2, respectively. In patients with a history of chronic kidney disease and cardiovascular high risk, fewer NSAIDs were prescribed, while they were used most frequently in patients with a risk for gastrointestinal adverse events. The prescription was considered adequate in 46.5% of diabetic patients. The main causes of inappropriate use were the inadequate prescription of NSAIDs (25.2%), and the use of any NSAID other than naproxen (20.6%). CONCLUSIONS: The most prescribed NSAIDs were those showing a low cardiovascular risk profile. Treatment with NSAIDs was inadequate in more than half of the patients. Risk factors for cardiovascular, and especially gastrointestinal, events must be considered in order to avoid its use when not indicated, as well as the use of any NSAIDs other than naproxen.

Stentoplasty effectiveness and safety for the treatment of osteoporotic vertebral fractures: a systematic review.

UNLABELLED: To assess the effectiveness and safety of stentoplasty in people with osteoporotic vertebral body fractures. A systematic search of databases including MEDLINE, EMBASE and Cochrane library, between others, was conducted to June 9, 2014. Clinical trials and observational studies that included alive adults with osteoporotic vertebral body fractures and the comparators were the intervention himself, vertebroplasty or balloon kyphoplasty were selected. Quality of evidence was graded according to the GRADE approach. Two review authors independently selected studies, assessed risk of bias and extracted data. Forty-two citations were identified during the search. After removing duplicates, five studies were included: two clinical trials and three observational studies. Stentoplasty, showed higher rate of adverse events related to material (P=0.043) and cuff pressure (P=0.014) in comparison to kyphoplasty. There was no difference between two procedures in terms of reduction of kyphosis, time of exposure to radiation or postoperative loss of cement. Stentoplasty in comparison to vertebroplasty, showed an improvement of restoration of vertebral height (P=0.042), kyphosis correction and volume of bone cement. No differences were found between two procedures in terms of loss of vertebral body volume. Based on observational studies, stentoplasty improved vertebral height, pain and functional disability at 6 and 12months follow-up, and corrected the angle vertebral fractures in patients with osteoporotic vertebral body. Stentoplasty was presented as a safe procedure in short-medium term, with a low complication rate, a reduced loss of cement and new vertebral body fractures lower rates. Stentoplasty improves vertebral height, reduces the pain and functional disability and correct the vertebral angle in patients with osteoporotic vertebral body fracture with minimum adverse events. Stentoplasty is comparable to kyphoplasty in terms of correction of kyphosis, time of exposure to radiation and cement postoperative loss, and comparable to vertebroplasty in terms of restoration of vertebral height correction and bone cement volume. LEVEL OF EVIDENCE: Level II systematic review.

[Clinical Psychology in Primary Care: A Descriptive Study of One Year of Operation]. / Psicología Clínica en Atención Primaria: descripción de un año de asistencia.

OBJECTIVE: Our aim is to present the first year of operation of a Clinical Psychology service in a Primary Care setting. MATERIAL AND METHOD: A descriptive study was performed by analysing the requests and the care intervention of the Psychology Service, in collaboration with 36 general practitioners (33% of the staff), belonging to 6 health centres. Within the one year period, 171 outpatients from 15 years and older were referred with mild psychological disorders (> 61 in the global assessment functioning scale, APA, 2002). RESULTS: A total of 111 outpatients received psychological care. The main diagnoses were adaptation disorder, affective disorder, and anxiety. More than half (54.82%) of them achieved a full recovery. After a year follow up, a drop of 25.19% was observed in medicines use. CONCLUSIONS: The Primary Care Psychology team is a halfway unit between Primary Care practitioners and specialised units in order to deal with mild mental symptomatology which otherwise could be undertreated. It represents an important support for practitioners. Secondly, the early intervention can prevent mental problems becoming chronic, as shown by the drop in medication use. In spite of the not very high agreement between the practitioner's diagnoses and those made by the Psychology unit, it has set up an important means of communication and with direct and immediate interdisciplinary action. This should eventually lead to savings in economic resources and human suffering.
