Association between type 2 diabetes and depressive symptoms after a 1-year follow-up in an older adult Mediterranean population.

OBJECTIVES: To examine the cross-sectional association between baseline depressive symptoms and the presence of type 2 diabetes (T2D), and its association with glycated hemoglobin (HbA1c) and other metabolic variables, and the prospective association of depressive symptoms and HbA1c after 1 year of follow-up. METHODS: n = 6224 Mediterranean older adults with overweight/obesity and metabolic syndrome (48% females, mean age 64.9 ± 4.9 years) were evaluated in the framework of the PREDIMED-Plus study cohort. Depressive symptoms were assessed using the Beck Depression Inventory-II and HbA1c was used to measure metabolic control. RESULTS: The presence of T2D increased the likelihood of higher levels of depressive symptoms (χ2 = 15.84, p = 0.001). Polynomial contrast revealed a positive linear relationship (χ2 = 13.49, p = 0.001), the higher the depressive symptoms levels, the higher the prevalence of T2D. Longitudinal analyses showed that the higher baseline depressive symptoms levels, the higher the likelihood of being within the HbA1c ≥ 7% at 1-year level (Wald-χ2 = 24.06, df = 3, p < .001, for the full adjusted model). Additionally, depressive levels at baseline and duration of T2D predicted higher HbA1c and body mass index, and lower physical activity and adherence to Mediterranean Diet at 1 year of follow-up. CONCLUSIONS: This study supports an association between T2D and the severity of depressive symptoms, suggesting a worse metabolic control from mild severity levels in the short-medium term, influenced by lifestyle habits related to diabetes care. Screening for depressive symptoms and a multidisciplinary integrative therapeutic approach should be ensured in patients with T2D.

Placental concentrations of xenoestrogenic organochlorine pesticides and polychlorinated biphenyls and assessment of their xenoestrogenicity in the PA-MAMI mother-child cohort.

BACKGROUND: Organochlorine pesticides (OCPs) and polychlorinated biphenyls (PCB), they have contributed to the exposure of women to persistent organic pollutants (POPs). These compounds can cross the placental barrier and interfere with the hormonal system of newborns. AIM: To determine concentrations of OCPs and PCBs and their xenoestrogenic activity in placentas of women from the PA-MAMI cohort of Panama. METHODS: Thirty-nine placenta samples from women in the Azuero peninsula (Panama) were analyzed. Five OCPs [p-p'-dichlorodiphenyldichloroethylene (p-p'-DDE), beta-hexachlorohexane (ß-HCH), γ-hexachlorohexane (lindane), hexachlorobenzene (HCB) and mirex] and three PCB congeners (PCB-138, PCB-153 and PCB-180) were quantified in placenta extracts. The xenoestrogenic activity of extracts was assessed with the E-Screen bioassay to estimate the total effective xenoestrogen burden (TEXB). RESULTS: All placental samples were positive for at least three POP residues and >70% for at least six. The frequencies of quantified OCPs ranged from 100% for p,p'-DDE and HCB to 30.8% for ß-HCH. The highest median concentration was for lindane (380.0 pg/g placenta), followed by p,p'-DDE (280.0 pg/g placenta), and HCB (90.0 pg/g placenta). Exposure to p,p'-DDE was associated with greater meat consumption, suggesting that animal fat is a major source of exposure to DDT metabolites. The frequency of detected PCBs ranged between 70 and 90%; the highest median concentration was for PCB 138 (17.0 pg/g placenta), followed by PCB 153 (16.0 pg/g placenta). All placentas were positive in the estrogenicity bioassay with a median TEXB-α of 0.91 pM Eeq/g of placenta. Exposure to lindane was positively associated with the xenoestrogenicity of TEXB- α, whereas this association was negative in the case of exposure to PCB 153. CONCLUSIONS: To our best knowledge, this study contributes the first evidence on the presence of POPs and xenoestrogenic burden in placentas from Latin-American women. Given concerns about the consequences of prenatal exposure to these compounds on children's health, preventive measures are highly recommended to eliminate or minimize the risk of OCP exposure during pregnancy.

Arthroscopic Needling Technique for the Treatment of Wrist Ganglia.

Background Synovial cysts (SCs) are the most frequent wrist tumors; the arthroscopic treatment presents good results when surgery is indicated for symptomatic or patients with cosmetic concerns. The tumoral lesion should be arthroscopically decompressed or drained toward the inside of the joint through pedicle opening and resection of a small portion of the capsule. Hence, the cyst pedicle must be found for the success of this technique. Description of Technique Some tricks have already been described to facilitate SC location during arthroscopy. We describe an indirect technique that employs an 18-G needle to enhance SC pedicle location and drainage. The technique involves a puncture on the interval of the carpal extrinsic ligaments where the pedicle is suspected to be remain. When found, cyst is drained with a single-puncture motion of the need which promotes cyst content extravasation due to pressure toward the joint. Patients and Methods This method has been employed in 16 patients, including 9 with dorsal cysts, and seven with volar cysts. Results All patients presented complete recovery and symptom improvement in up to 30 days, with total disappearance of the cyst. There were no relapses or severe complications within the 12-month follow-up. Conclusion This is a safe, useful technique that facilitates location of intra-articular cyst pedicle, thus avoiding unnecessary damage in healthy tissues with no increased costs.

Expression of 20 SCPP genes during tooth and bone mineralization in Senegal bichir.

The African bichir (Polypterus senegalus) is a living representative of Polypteriformes. P. senegalus possesses teeth composed of dentin covered by an enameloid cap and a layer of collar enamel on the tooth shaft, as in lepisosteids. A thin layer of enamel matrix can also be found covering the cap enameloid after its maturation and during the collar enamel formation. Teleosts fish do not possess enamel; teeth are protected by cap and collar enameloid, and inversely in sarcopterygians, where teeth are only covered by enamel, with the exception of the cap enameloid in teeth of larval urodeles. The presence of enameloid and enamel in the teeth of the same organism is an opportunity to solve the evolutionary history of the presence of enamel/enameloid in basal actinopterygians. In silico analyses of the jaw transcriptome of a juvenile bichir provided twenty SCPP transcripts. They included enamel, dentin, and bone-specific SCPPs known in sarcopterygians and several actinopterygian-specific SCPPs. The expression of these 20 genes was investigated by in situ hybridizations on jaw sections during tooth and dentary bone formation. A spatiotemporal expression patterns were established and compared with previous studies of SCPP gene expression during enamel/enameloid and bone formation. Similarities and differences were highlighted, and several SCPP transcripts were found specifically expressed during tooth or bone formation suggesting either conserved or new functions of these SCPPs.

Short-term outcomes of chemoradiotherapy and local excision versus total mesorectal excision in T2-T3ab,N0,M0 rectal cancer: a multicentre randomised, controlled, phase III trial (the TAU-TEM study).

BACKGROUND: The standard treatment of T2-T3ab,N0,M0 rectal cancers is total mesorectal excision (TME) due to the high recurrence rates recorded with local excision. Initial reports of the combination of pre-operative chemoradiotherapy (CRT) and transanal endoscopic microsurgery (TEM) have shown reductions in local recurrence. The TAU-TEM study aims to demonstrate the non-inferiority of local recurrence and the improvement in morbidity achieved with CRT-TEM compared with TME. Here we describe morbidity rates and pathological outcomes. PATIENTS AND METHODS: This was a prospective, multicentre, randomised controlled non-inferiority trial including patients with rectal adenocarcinoma staged as T2-T3ab,N0,M0. Patients were randomised to the CRT-TEM or the TME group. Patients included, tolerance of CRT and its adverse effects, surgical complications (Clavien-Dindo and Comprehensive Complication Index classifications) and pathological results (complete response in the CRT-TEM group) were recorded in both groups. Patients attended follow-up controls for local and systemic relapse. TRIAL REGISTRATION: NCT01308190. RESULTS: From July 2010 to October 2021, 173 patients from 17 Spanish hospitals were included (CRT-TEM: 86, TME: 87). Eleven were excluded after randomisation (CRT-TEM: 5, TME: 6). Modified intention-to-treat analysis thus included 81 patients in each group. There was no mortality after CRT. In the CRT-TEM group, one patient abandoned CRT, 1/81 (1.2%). The CRT-related morbidity rate was 29.6% (24/81). Post-operative morbidity was 17/82 (20.7%) in the CRT-TEM group and 41/81 (50.6%) in the TME group (P < 0.001, 95% confidence interval 42.9% to 16.7%). One patient died in each group (1.2%). Of the 81 patients in the CRT-TEM group who received the allocated treatment, 67 (82.7%) underwent organ preservation. Pathological complete response in the CRT-TEM group was 44.3% (35/79). In the TME group, pN1 were found in 17/81 (21%). CONCLUSION: CRT-TEM treatment obtains high pathological complete response rates (44.3%) and a high CRT compliance rate (98.8%). Post-operative complications and hospitalisation rates were significantly lower than those in the TME group. We await the results of the follow-up regarding cancer outcomes and quality of life.

Patient-specific iPSC-derived cellular models of LGMDR1.

Limb-girdle muscular dystrophy recessive 1 (LGMDR1) represents one of the most common types of LGMD in the population, where patients develop a progressive muscle degeneration. The disease is caused by mutations in calpain 3 gene, with over 500 mutations reported to date. However, the molecular events that lead to muscle wasting are not clear, nor the reasons for the great clinical variability among patients, and this has so far hindered the development of effective therapies. Here we generate human induced pluripotent stem cells (iPSCs) from skin fibroblasts of 2 healthy controls and 4 LGMDR1 patients with different mutations. The generated lines were able to differentiate into myogenic progenitors and myotubes in vitro and in vivo, upon a transient PAX7 overexpressing protocol. Thus, we have generated myogenic cellular models of LGMDR1 that harbor different CAPN3 mutations within a human genetic background, and which do not derive from muscular biopsies. These models will allow us to investigate disease mechanisms and test therapies. Despite the variability found among iPSC lines that was unrelated to CAPN3 mutations, we found that patient-derived myogenic progenitors and myotubes express lower levels of DMD, which codes a key protein in satellite cell regulation and myotube maturation.

Isquemia mesentérica: manejo endovascular

La isquemia mesentérica es una condición que puede volverse muy grave y ser letal, más aún en los casos agudos. Un tratamiento precoz es muy importante. Se presentaron cuatro casos consecutivos tratados por nuestro equipo con trombosis, o disección o aneurismas de arterias mesentérica superior y tronco celíaco, se revisaron las indicaciones y se evaluaron los tratamientos llevados a cabo. Se utilizaron procedimientos endovasculares en todos, técnicamente en forma exitosa, evitando que progrese a un desenlace peligroso. Hubo diversidad de técnicas endovasculares adaptándolas a cada caso. En ningún paciente se requirió un acceso quirúrgico abierto para completar el tratamiento realizando las intervenciones prontas. El manejo endovascular de las lesiones mesentéricas es factible y replicable, y en nuestros casos podría haber prevenido una necrosis intestinal así como la necesidad de cirugías resectivas.

SUMMARY Mesenteric ischaemia is a condition that may be very severe and potentially lethal particularly in the acute presentation. Early treatment is crucial. We present four consecutive cases managed by our team with thrombosis or dissection or aneurysm of the superior mesenteric artery and the celiac trunk reviewing indications and treatment implemented. Multiple successful endovascular procedures were used in all cases avoiding progression to lethal consequences. None of the patients required an open surgical procedure. Therefore, endovascular procedures are feasible in these patients avoiding intestinal necrosis as well as the need for open surgeries.

Effect of bovine viral diarrhea virus on subsequent infectivity of bovine gammaherpesvirus 4 in endometrial cells in primary culture: An in vitro model of viral co-infection.

Bovine viral diarrhea virus (BVDV) and bovine gammaherpesvirus 4 (BoHV-4) infect the uterus of cattle, being responsible for huge economic losses. Most of the pathogenesis of BoHV-4 in the bovine reproductive tract has been elucidated by conducting tests on primary cultures. Thus, it is important to have optimal in vitro conditions, avoiding the presence of other pathogens that can alter the results. BVDV is one of the most frequent viral contaminants of cell cultures. Considering that non-cytopathic (NCP) BVDV biotype can generate persistently infected (PI) cattle, which are the major source for virus transmission in susceptible herds, it is important to check products derived from cattle that are intended to be used in research laboratories. The aim of this work was to evaluate how the natural infection of bovine endometrial cells (BEC) with a NCP BVDV strain (BEC + BVDV) affects BoHV-4 replication. We have demonstrated a delay in BoHV-4 gene expression and a decrease in viral load in the extracellular environment in BEC + BDVD cells compared to BEC (BVDV-free) cells. These results confirm that replication of BoHV-4 in BEC primary cultures is affected by previous infection with BVDV. This finding highlights the importance of ruling out BVDV infection in bovine primary cell cultures to avoid biological interference or misinterpretation of results at the time of performing in vitro studies with BoHV-4.

Gene expression and in vitro replication of bovine gammaherpesvirus type 4.

In vitro cell cultures are widely used models for dissecting cellular and molecular mechanisms that lead to certain physiological conditions and diseases. The pathogenesis of BoHV-4 in the bovine reproductive tract has been studied by conducting tests on primary cultures. However, many questions remain to be answered about the role of BoHV-4 in endometrial cells. The aim of this study was to compare the replication and gene expression of BoHV-4 in cell lines and bovine reproductive tract primary cells as an in vitro model for the study of this virus. We demonstrated that BoHV-4 strains differ in their in vitro growth kinetics and gene expression but have the same cell type preference. Our results demonstrate that BoHV-4 replicates preferentially in bovine endometrial cells (BEC). However, its replication capacity extends to various cell types, since all cells that were tested were permissive to BoHV-4 infection. The highest virus titers were obtained in BEC cells. Nevertheless, virus replication efficiency could not be fully predicted from the mRNA expression profiles. This implies that there are multiple cell-type-dependent factors and strain properties that determine the level of BoHV-4 replication. The results of this study provide relevant information about the in vitro behavior of two field isolates of BoHV-4 in different cell cultures. These findings may be useful for the design of future in vitro experiments to obtain reliable results not only about the pathogenic role of BoHV-4 in the bovine female reproductive tract but also in the development of efficient antiviral strategies.

Relación entre la inteligencia emocional y el burnout en los médicos de Atención Primaria / Relationship between emotional intelligence and burnout syndrome in Primary Healthcare doctors

OBJETIVO: Evaluar la relación de la inteligencia emocional (IE) con el síndrome de burnout (BO) en los médicos de Atención Primaria. MATERIAL Y MÉTODOS: Estudio descriptivo transversal. EMPLAZAMIENTO: todos los centros de salud y consultorios del Principado de Asturias. PARTICIPANTES: médicos de Atención Primaria que estén en activo. Intervención: en abril de 2018 se envió un cuestionario anónimo autoadministrado con variables sociodemográficas, laborales y las escalas validadas TMMS-24 (IE) y MBI (BO). VARIABLES: la variable dependiente fue el BO. Como variables independientes se tomaron las 3 dimensiones de la IE, la edad, el sexo, el estado civil, el número de hijos, el tipo de formación, el tipo de contrato, el tiempo trabajado, las horas de guardia, los pacientes al día, el cupo, el ámbito rural o urbano, el área sanitaria, la relación con enfermería/hospital y la docencia. Análisis estadístico: inferencia bayesiana. RESULTADOS: Se enviaron 647 encuestas, participando 374 sujetos (tasa de respuesta del 57,8%). La distribución posterior de la prevalencia de BO fue del 64,5% [índice de credibilidad 95%: 59,7 a 69,2]. Encontramos asociación del BO con las 3 dimensiones de la IE; tener más habilidades emocionales disminuye el riesgo de presentar BO. Mostraron, además, incrementar la odds de prevalencia de BO la edad, el tipo de contrato, el ámbito urbano y la media de pacientes/día. Mostraron disminuir la odds de prevalencia tener hijos y ser tutor. CONCLUSIONES: Cabe destacar el elevado BO de los médicos de Atención Primaria, más de uno de cada 2 médicos están quemados. Por tanto, según resultados obtenidos, proponemos profundizar en la adquisición de habilidades relacionadas con la IE y mejorar las condiciones laborales en Atención Primaria

AIM: The purpose of this study is to analyse the relationship between emotional intelligence (EI) and burnout syndrome (BOS) in doctors in Primary Health Care. MATERIAL AND METHODS: Cross-sectional descriptive study. SETTING: All healthcare centres and clinics in Asturias. PARTICIPANTS: Doctors of Primary Health Care who are active. INTERVENTION: In April 2018, an anonymous self-administered questionnaire was sent to all concerned. It included sociodemographic data, employment data, and TMMS-24 (EI) and MBI (BOS) validated scales. VARIABLES: BOS as a dependent variable. Three dimensions of EI, age, sex, marital status, number of children, form of training, contract type, time worked, on-call hours, number of patients per day, quota, rural or urban setting, healthcare area, relationship with nursing/hospital, and teaching as independent variables. Statistical analysis: Bayesian inference. RESULTS: A total of 647 questionnaires were sent, and 374 subjects took part in the study (response rate: 57.8%). The subsequent distribution of BOS prevalence was 64.5% [95% credibility index: 59.7-69.2]. BOS was associated with 3 dimensions of the EI, and to have higher social skills decreased the risk of presenting with BOS. Age, contract type, urban setting, and number of patients per day tended to increase the odds of prevalence of BOS. Having children or being a guardian tended to decrease the odds of prevalence. CONCLUSIONS: The high level of BOS in Primary Health Care doctors should be pointed out, with more than one out of 2 doctors having burnout. Therefore, we suggest looking into how emotional skills are achieved, and also how to improve working conditions in Primary Health Care

Release-Recapture Test of Dispersal and Survival of Sterile Males of Ceratitis capitata (Diptera: Tephritidae).

The sterile insect technique is used around the world to suppress or eradicate populations of Ceratitis capitata (Wiedemann) with successful results. It consists of inundative releases of sterile insects into a wide area to reduce reproduction in a field population of the same species. It is necessary to know the dispersion of the sterile males in the field in order to define the maximum distance between the release points that ensures the distribution of the sterile flies in the entire target area. The release methods may vary depending on the area to be covered and the resources available. Manual ground release requires less technology. The aim of this research was to estimate the ability of sterile males to survive and disperse in the field, in the two main areas of citrus production in Uruguay. A release of 20,000 sterile males of C. capitata TslV8 (-inv D53) was performed at the central point of each area defined for the trials. Around these points, a network of 54 Jackson traps baited with trimedlure was installed forming five concentric rings, which were placed on days 1, 3, 5, and 7 after the release and were removed at 24 h in all cases. The emergence rate, flight ability, dispersion, and longevity were estimated. The standard distances obtained by the regression models were 127 m and 131 m for Salto and San José respectively. In Salto, the traps had catches until the eighth day, and in San José, there were no catches after the sixth day.

The genetic diversity of multiple sclerosis risk among Hispanic and African American populations living in the United States.

BACKGROUND: Substantial progress has been made toward unraveling the genetic architecture of multiple sclerosis (MS) within populations of European ancestry, but few genetic studies have focused on Hispanic and African American populations within the United States. OBJECTIVE: We sought to test the relevance of common European MS risk variants outside of the major histocompatibility complex (n = 200) within these populations. METHODS: Genotype data were available on 2652 Hispanics (1298 with MS, 1354 controls) and 2435 African Americans (1298 with MS, 1137 controls). We conducted single variant, pathway, and cumulative genetic risk score analyses. RESULTS: We found less replication than statistical power suggested, particularly among African Americans. This could be due to limited correlation between the tested and causal variants within the sample or alternatively could indicate allelic and locus heterogeneity. Differences were observed between pathways enriched among the replicating versus all 200 variants. Although these differences should be examined in larger samples, a potential role exists for gene-environment or gene-gene interactions which alter phenotype differentially across racial and ethnic groups. Cumulative genetic risk scores were associated with MS within each study sample but showed limited diagnostic capability. CONCLUSION: These findings provide a framework for fine-mapping efforts in multi-ethnic populations of MS.

Eficacia de la cirugía bariátrica-metabólica en pacientes con obesidad y diabetes mellitus tipo 2 / Efficacy of bariatric-metabolic surgery in patients with obesity and type 2 diabetes mellitus

La prevalencia de la diabetes mellitus tipo 2 está incrementando rápidamente a nivel mundial de manera paralela a la epidemia de obesidad. El número de personas con diabetes, alrededor del mundo, se ha duplicado en los últimos 20 años; una de las características más preocupantes de este rápido crecimiento es el aparecimiento de diabetes tipo 2 en niños, adolescentes y adultos jóvenes. Debido a la reducción de la esperanza de vida causada por las morbilidades producidas por la diabetes, los pacientes que sufren de esta patología requieren un manejo integral. La cirugía bariátrica / metabólica ha demostrado que: • Mejora significativamente el control glucémico. • Reduce los factores de riesgo cardiovasculares. • Incluso ha demostrado la posibilidad de producir remisión de la diabetes tipo 2, hipertensión arterial y otras comorbilidades asociadas con la obesidad. Los resultados de múltiples estudios demuestran claramente la eficacia de la cirugía metabólica en el control glucémico y de otras comorbilidades asociadas con la diabetes tipo 2 y la obesidad; se observa, con mucha frecuencia, casos de remisión de la diabetes, incluso hasta 5 años después de la intervención quirúrgica. Por esta razón, la Asociación Americana para la Diabetes (ADA) considera a la cirugía bariátrica como una opción terapéutica viable en pacientes obesos con diabetes mellitus tipo 2.Las cirugías gastrointestinales diseñadas para controlar la obesidad pueden mejorar la homeostasis de la glucosa más efectivamente que el tratamiento farmacológico-clínico y producir cambios importantes en el estilo de vida; incluso, en un considerable número de pacientes, se logra la remisión de la diabetes tipo 2. (AU)

The prevalence of type 2 diabetes mellitus is rapidly increasing to global level parallel to the epidemic that obesity. The number of people with diabetes, around the world, have doubled in the last 20 years; one of the most worrisome features of this rapid growth It is the appearance of type 2 diabetes in children, adolescents and young adults. Due to the reduction in life expectancy caused by morbidities produced by diabetes, patients suffering from this pathology require comprehensive management bariatric / metabolic surgery has shown that: • Significantly improves glycemic control. • Reduces cardiovascular risk factors. • It has even demonstrated the possibility of producing diabetes remission type 2, arterial hypertension and other comorbidities associated with obesity. The results of multiple studies clearly demonstrate the effectiveness of the metabolic surgery in glycemic control and other associated comorbidities with type 2 diabetes and obesity; cases are very often observed of remission of diabetes, even up to 5 years after the intervention surgical For this reason, the American Diabetes Association (ADA) considers bariatric surgery as a viable therapeutic option in obese patients with type 2 diabetes mellitus. Gastrointestinal surgeries designed to control obesity can improve glucose homeostasis more effectively than treatment clinical pharmacological and produce important changes in lifestyle; even, in a considerable number of patients, remission of the type 2 diabetes.

Análisis de la atención a la población pediátrica por médicos de familia en un punto de atención continuada / Analysis of the healthcare of the paediatric population by general practitioners in a continuous care point

OBJETIVO: El objetivo principal de este estudio es analizar el manejo de las urgencias pediátricas en atención primaria por parte de los médicos de familia. El objetivo secundario es estimar el grado de adecuación de las derivaciones hospitalarias. MATERIAL Y MÉTODOS: Se realizó un estudio observacional descriptivo retrospectivo. Se analizaron las visitas realizadas por los menores de 14 años atendidos a lo largo de un año en horario de atención continuada en una zona básica de salud, tras un muestreo aleatorio por conglomerados monoetápico de 45 días. RESULTADOS: Se atendieron un total de 447 consultas urgentes por pacientes en edad pediátrica, con una media de edad de 6,83años (DE=3,82). Se resolvieron in situ el 92,8% de las consultas urgentes realizadas por menores de 14 años. El porcentaje de derivaciones al servicio hospitalario fue del 7,2% (IC95%: 4,9-10). Al 56% (IC95%: 37,7-73,6) de los niños derivados se les realizó algún tipo de intervención hospitalaria (pruebas, tratamientos, valoración por otros especialistas no pediatras, observación y/o ingreso). CONCLUSIONES: La tasa de derivación fue del 7,2%, que sitúa en el límite alto de lo encontrado en otros estudios. La mitad de los pacientes derivados requirieron algún tipo de intervención, por lo que podrían considerarse derivaciones justificadas. Además, se ha encontrado una buena concordancia (índice kappa=0,778) entre los diagnósticos desde atención primaria y el diagnóstico final de pediatría, por lo que se puede inferir que los diagnósticos realizados en edad pediátrica por médicos de familia son acertados

OBJECTIVE: The main objective of this study is to analyse the management of paediatric emergencies by Family Doctors in Primary Care. The secondary objective is to determine the appropriateness of hospital referrals. MATERIAL AND METHODS: A retrospective, observational, and descriptive study was performed. An analysis was carried out on the visits made by children less than 14years-old during one year in continued care opening hours in a basic health area, after single-stage cluster random sampling of 45 days. RESULTS: A total of 447 emergency consultations were made by paediatric patients with a mean age of 6.83years (SD=3.82). Almost all (92.8%) the emergency consultations made by children less than 14 years were resolved in situ. The referral rate to hospitals was 7.2% (95%CI: 4.9-10). Just over half (56%: 95%CI: 37.7-73.6) of the children referred had some type of hospital intervention (tests, treatments, assessments by other non-paediatric specialists, observation and or admission). CONCLUSIONS: The referral rate was 7.2%, which is in the upper limit of that found in other studies. Just over half of the children required some type of intervention, which could be considered as justified referrals. Furthermore, good agreement was found (Kappa index=0.778) between the diagnosis from Primary Care and the final diagnosis by paediatricians, inferring that the diagnosis made on paediatric patients by Family Doctors are correct

Phylogenetic and kinematic constraints on avian flight signals.

Many birds vocalize in flight. Because wingbeat and respiratory cycles are often linked in flying vertebrates, birds in these cases must satisfy the respiratory demands of vocal production within the physiological limits imposed by flight. Using acoustic triangulation and high-speed video, we found that avian vocal production in flight exhibits a largely phasic and kinematic relationship with the power stroke. However, the sample of species showed considerable flexibility, especially those from lineages known for vocal plasticity (songbirds, parrots and hummingbirds), prompting a broader phylogenetic analysis. We thus collected data from 150 species across 12 avian orders and examined the links between wingbeat period, flight call duration and body mass. Overall, shorter wingbeat periods, controlling for ancestry and body mass, were correlated with shorter flight call durations. However, species from vocal learner lineages produced flight signals that, on average, exceeded multiple phases of their wingbeat cycle, while vocal non-learners had signal periods that were, on average, closer to the duration of their power stroke. These results raise an interesting question: is partial emancipation from respiratory constraints a necessary step in the evolution of vocal learning or an epiphenomenon? Our current study cannot provide the answer, but it does suggest several avenues for future research.

Fluoride removal from natural volcanic underground water by an electrocoagulation process: Parametric and cost evaluations.

Excessive fluoride content in groundwater can cause serious risks to human health, and sources of groundwater intended for human consumption should be treated to reduce fluoride concentrations down to acceptable levels. In the particular case of the island of Tenerife (Canary Islands, Spain), the water supply comes mainly from aquifers of volcanic origin with a high content of fluorides that make them unacceptable for human consumption without prior conditioning treatment. The treatments that generate a high rejection of water are not acceptable because water is a scarce natural resource of high value. An electrocoagulation process was investigated as a method to treat natural groundwater from volcanic soils containing a hazardously high fluoride content. The operating parameters of an electrocoagulation reactor model with parallel plate aluminum electrodes were optimized for batch and continuous flow operations. In the case of the batch operation, acidification of the water improved the removal efficiency of fluoride, which was the highest at pH 3. However, operation at the natural pH of the water achieved elimination efficiencies between 82 and 92%, depending on the applied current density. An optimum current density of 5 mA/cm2 was found in terms of maximum removal efficiency, and the kinetics of fluoride removal conformed to pseudo-second-order kinetics. In the continuous-flow operation, with the optimal residence time of 10 min and a separation of 0.5 cm between the electrodes, it was observed that the current density that would be applied would depend on the initial concentration of fluoride in the raw water. Thus, an initial fluoride concentration of 6.02 mg/L required a current density >7.5 mA/cm2 to comply with the legal guidelines in the product water, while for an initial concentration of 8.98 mg/L, the optimal current density was 10 mA/cm2. Under these operating conditions, the electrocoagulation process was able to reduce the fluoride concentration of natural groundwater to below 1.5 mg/L according to WHO guidelines with an operating cost between 0.20 and 0.26 €/m3 of treated water.

Almost all (92.8%) the emergency consultations made by children less than 14years were resolved in situ. The referral rate to hospitals was 7.2% (95%CI: 4.9-10). Just over half (56%: 95%CI: 37.7-73.6) of the children referred had some type of hospital intervention (tests, treatments, assessments by other non-paediatric specialists, observation and or admission). CONCLUSIONS: The referral rate was 7.2%, which is in the upper limit of that found in other studies. Just over half of the children required some type of intervention, which could be considered as justified referrals. Furthermore, good agreement was found (Kappa index=0.778) between the diagnosis from Primary Care and the final diagnosis by paediatricians, inferring that the diagnosis made on paediatric patients by Family Doctors are correct.

Gut microbiota dysbiosis in a cohort of patients with psoriasis.

BACKGROUND: There is increasing evidence of the key role that the gut microbiota plays in inflammatory diseases. OBJECTIVES: To identify differences in the faecal microbial composition of patients with psoriasis compared with healthy individuals in order to unravel the microbiota profiling in this autoimmune disease. METHODS: 16S rRNA gene sequencing and bioinformatic analyses were performed with the total DNA extracted from the faecal microbiota of 19 patients with psoriasis and 20 healthy individuals from the same geographic location. RESULTS: Gut microbiota composition of patients with psoriasis displayed a lower diversity and different relative abundance of certain bacterial taxa compared with healthy individuals. CONCLUSIONS: The gut microbiota profile of patients with psoriasis displayed a clear dysbiosis that can be targeted for microbiome-based therapeutic approaches. What's already known about this topic? Psoriasis is a chronic inflammatory immune-mediated skin disease, the aetiology of which remains unclear. The human microbiota is a complex microbial community that inhabits our body and has been related with the maintenance of a healthy status. Several studies have focused on the skin microbiome and its connection with psoriasis although less attention has been focused on the potential role of the gut microbiota in psoriatic disease. What does this study add? This study unravels the gut microbiome dysbiosis present in a cohort of patients with psoriasis, compared with a healthy control group from the same geographical location. This study shows a lower bacterial diversity and different relative abundance of certain bacterial taxa in patients with psoriasis. We gain knowledge and insight into the microbiome alterations in psoriatic disease, opening new avenues for therapeutic approaches to reshape the human microbiome towards a healthy status.
