Correlation between the latitudinal profile of the 7Be air concentration and the Hadley cell extent in the Southern Hemisphere.

The cosmogenic radionuclide 7Be is one of the best tracers for aerosol transport since its half-life of 53 days is in the time scale of many atmospheric circulation phenomena. In this work, we analyze a 12-years-long daily time-series for the airborne 7Be concentration for nine air filtering stations in the Southern Hemisphere or close to it. The observed latitudinal distribution of 7Be concentration, with its maximum at the southern subtropical high-pressure belt, is similar to the one in the Northern Hemisphere. A good time correlation was found between the 7°-shift of the 7Be concentration latitudinal distribution and the seasonal displacement of the extent of the Hadley cell. This is consistent with tropopause folding events, mostly occurring in spring, being the main contribution for the injection of stratospheric 7Be into the descending branch of the Hadley cell.

Vimentin Regulates Chemokine Expression and NOD2 Activation in Brain Endothelium during Group B Streptococcal Infection.

Streptococcus agalactiae (group B Streptococcus, or GBS) is an opportunistic pathogen capable of causing invasive disease in susceptible individuals, including the newborn. Currently, GBS is the leading cause of meningitis in the neonatal period. We have recently shown that GBS interacts directly with host type III intermediate filament vimentin to gain access to the central nervous system. This results in characteristic meningeal inflammation and disease progression; however, the specific role of vimentin in the inflammatory process is unknown. Here, we investigate the contribution of vimentin to the pathogenesis of GBS meningitis. We show that a CRISPR-targeted deletion of vimentin in human cerebral microvascular endothelial cells (hCMEC) reduced GBS induction of neutrophil attractants interleukin-8 (IL-8) and CXCL-1 as well as NF-κB activation. We further show that inhibition of vimentin localization also prevented similar chemokine activation by GBS. One known chemokine regulator is the nucleotide-binding oligomerization domain containing protein 2 (NOD2), which is known to interact directly with vimentin. Thus, we hypothesized that NOD2 would also promote GBS chemokine induction. We show that GBS infection induced NOD2 transcription in hCMEC comparably to the muramyl dipeptide (MDP) NOD2 agonist, and the chemokine induction was reduced in the presence of a NOD2 inhibitor. Using a mouse model of GBS meningitis, we also observed increased NOD2 transcript and NOD2 activation in brain tissue of infected mice. Lastly, we show that NOD2-mediated IL-8 and CXCL1 induction required vimentin, further indicating the importance of vimentin in mediating inflammatory responses in brain endothelium.

Direct Structural Identification and Quantification of the Split-Vacancy Configuration for Implanted Sn in Diamond.

We demonstrate formation of the ideal split-vacancy configuration of the Sn-vacancy center upon implantation into natural diamond. Using ß^{-} emission channeling following low fluence ^{121}Sn implantation (2×10^{12} atoms/cm^{2}, 60 keV) at the ISOLDE facility at CERN, we directly identified and quantified the atomic configurations of the Sn-related centers. Our data show that the split-vacancy configuration is formed immediately upon implantation with a surprisingly high efficiency of ≈40%. Upon thermal annealing at 920 °C ≈30% of Sn is found in the ideal bond-center position. Photoluminescence revealed the characteristic SnV^{-} line at 621 nm, with an extraordinarily narrow ensemble linewidth (2.3 nm) of near-perfect Lorentzian shape. These findings further establish the SnV^{-} center as a promising candidate for single photon emission applications, since, in addition to exceptional optical properties, it also shows a remarkably simple structural formation mechanism.

[Main causes of orthopedic external consultation in a Second Level Clinic in Mexico]. / Principales motivos de consulta externa ortopédica en un hospital de segundo nivel en México.

INTRODUCTION: The epidemiology of diseases allows the generation of preventive measures, for the modification of their natural evolution or to prevent their appearance. In second-level hospitals of care, most of the pathologies of each medical specialty are treated. Therefore, knowing the main reasons for external consultation in orthopedics and their seasonal predominance is a tool for implementing strategies for the benefit of patients. MATERIAL AND METHODS: Observational study carried out with the patient population of the external orthopedic consultation service of a second-level hospital of care, from January to December 2017. Patients over the age of 18 who first attended consultation were included. RESULTS: 11,704 consultations granted in the period, 7,862 (67.17%) women and 3,842 (32.82%) men. The average age of patients was 51.84 ± 0.14. The most common cause of consultation was arthropathies (47.65%). During the autumn, the largest number of consultations (32.33) were granted. CONCLUSIONS: Arthropathies, specifically gonarthrosis, were the main reason for external consultation, accounting for nearly half of the consultations granted. It is transcendental to identify the modifiable risk factors of these pathologies with the aim of reducing the negative impact it generates at the functional, economic and quality of life level. Clinical relevance: Further epidemiological studies on orthopedic pathologies will improve preventive strategies and optimize resources to improve patient care.

En los hospitales de segundo nivel de atención se tratan la mayor parte de las patologías de cada especialidad médica. Por lo tanto, saber los principales motivos de consulta externa en ortopedia y su predominio estacional es una herramienta para la implementación de estrategias en beneficio de los pacientes. MATERIAL Y MÉTODOS: Estudio observacional realizado con la población de pacientes del servicio de consulta externa de ortopedia de un hospital de segundo nivel de atención de Enero a Diciembre del año 2017. Se incluyeron pacientes mayores de 18 años que acudieron a consulta por primera vez. RESULTADOS: De 11,704 consultas otorgadas en el período, 7,862 (67.17%) fueron mujeres y 3,842 (32.82%) hombres. La edad promedio de los pacientes fue de 51.84 ± 0.14. La causa más frecuente de consulta fueron las artropatías (47.65%). Durante el otoño se otorgó el mayor número de consultas (32.33%). CONCLUSIONES: Las artropatías, específicamente la gonartrosis, fue el principal motivo de consulta externa, representando casi la mitad de las consultas otorgadas. Es transcendental identificar los factores de riesgo modificables de estas patologías con el objetivo de disminuir el impacto negativo que genera a nivel funcional, económico y de calidad de vida. Importancia clínica: La realización de más estudios epidemiológicos sobre las patologías ortopédicas permitirá mejorar las estrategias preventivas y optimizar los recursos para mejorar la atención de los pacientes.

Aleteo auricular con conducción auriculoventricular 1: 1 descripción de un caso atrial / Flutter with 1: 1 atrioventricular conduction. case report

El aleteo auricular (AA) con conducción auriculoventricular 1:1 es una condición de presentación infrecuente en la práctica clínica, se da debido a diversos factores entre los cuales los más importantes son la presencia de vías accesorias concomitantes o uso de ciertos medicamentos antiarrítmicos, el AA con conducción 1 a 1 cuando se desarrolla constituye una emergencia médica ya que tiene una frecuencia cardíaca regular y presenta QRS ancho puede confundirse con una taquicardia ventricular. Cuando se presenta esta condición se produce frecuentemente inestabilidad hemodinámica del paciente, por lo que se debe hacer su diagnóstico y tratamiento a la brevedad posible. En el presente reporte presentamos el caso de un paciente previamente portador de marcapasos que desarrolla una taquicardia de QRS ancho regular, que se diagnostica finalmente como AA con conducción 1 a 1, tratado con fármacos antiarrítmicos en primera instancia, logrando disminuir la frecuencia cardíaca y posteriormente la reversión del mismo.

The atrial flutter (AF) with 1 to 1 atrio-ventricular (AV) conduction it's a rare medical condition secondary to several factors among which the most important are the association whit AV accessory pathways, or secondary to the use of some antiarrhythmic drugs. The AF with 1 to 1 AV conduction is a medical emergency and since it has a regular heart rate and presents wide QRS complex it can be confused with a ventricular tachycardia. When this condition occurs, it leads to hemodynamic instability of the patient, and that is why the diagnosis and treatment of this entity should be made as soon as possible. In the present report we present the case of a patient whit a previous pacemaker implantation who develops a regular wide QRS tachycardia, which is diagnosed as AF with 1 to 1 conduction and treated with antiarrhythmic drugs, first achieving a reduction in the heart rate and subsequently reaching its reversion

Tension hydrothorax: Emergency decompression of a pleural cause of cardiac tamponade.

INTRODUCTION: A tension hydrothorax is defined as a massive pleural effusion presenting with hemodynamic abnormalities secondary to mediastinal compression. In these patients pleural volume increases intrathoracic pressure to the point of compromising diastolic filling and cardiac output simulating a cardiac tamponade physiology. This is an uncommon yet potentially fatal medical emergency that if left untreated may progress to cardiac arrest. Early detection and rapid intervention of these patients prevents cardiorespiratory collapse. CASE PRESENTATION: We present a two-case report of patients presenting with malignant tension hydrothoraxes decompressed with ultrasound-guided thoracentesis and tube thoracostomy in the ED. CONCLUSION: Although these life-saving decompressive interventions appear simple, not having proper training is an independent factor for chest tube and thoracentesis complications. Courses and simulation training can benefit physicians to minimize potential complications when managing emergency conditions such as tension hydrothoraxes which continue to be a medical challenge. Whether thoracentesis or thoracostomy is superior in managing this condition remains in debate and a clinical dilemma.

[The cost of polypharmacy in patients with type 2 diabetes mellitus]. / Costo de la polifarmacia en el paciente con diabetes mellitus tipo 2.

BACKGROUND: Polypharmacy or the concomitant use of three or more medications, may increase the complexity of health care and its costs. AIM: To determine the costs of polypharmacy in patients with Type 2 Diabetes Mellitus in a Mexican population sample. PATIENTS AND METHODS: Analysis of health care costs in 257 patients with Type 2 Diabetes Mellitus from two family care facilities, who had at least five consultations during one year. The cost of professional care by family physicians, pharmacological care and medications were considered to calculate the total expenses. The price of medications and the number of units consumed in one year were used to determine pharmacological expenses. Medications were grouped to determine costs derived from complications and concomitant diseases. Costs were calculated in US dollars (USD). RESULTS: The mean cost derived from family physician fees was USD 82.32 and from pharmacy fees USD 29.37. The mean cost of medications for diabetes treatment was USD 33.31, for the management of complications USD 13.9 and for management of concomitant diseases USD 23.7, rendering a total cost of USD 70.92. Thus, the total annual care cost of a diabetic patient was USD 182.61. CONCLUSIONS: Medications represent less than 50% of total expenses of diabetic patients with polypharmacy.

Structure of Self-Assembled Mn Atom Chains on Si(001).

Mn has been found to self-assemble into atomic chains running perpendicular to the surface dimer reconstruction on Si(001). They differ from other atomic chains by a striking asymmetric appearance in filled state scanning tunneling microscopy (STM) images. This has prompted complicated structural models involving up to three Mn atoms per chain unit. Combining STM, atomic force microscopy, and density functional theory we find that a simple necklacelike chain of single Mn atoms reproduces all their prominent features, including their asymmetry not captured by current models. The upshot is a remarkably simpler structure for modeling the electronic and magnetic properties of Mn atom chains on Si(001).

A relationship between acute respiratory illnesses and weather.

Weekly data from 7 years (2004-2010) of primary-care counts of acute respiratory illnesses (ARIs) and local weather readings were used to adjust a multivariate time-series vector error correction model with covariates (VECMX). Weather variables were included through a partial least squares index that consisted of weekly minimum temperature (coefficient = - 0·26), weekly median of relative humidity (coefficient = 0·22) and weekly accumulated rainfall (coefficient = 0·5). The VECMX long-term test reported significance for trend (0·01, P = 0·00) and weather index (1·69, P = 0·00). Short-term relationship was influenced by seasonality. The model accounted for 76% of the variability in the series (adj. R 2 = 0·76), and the co-integration diagnostics confirmed its appropriateness. The procedure is easily reproducible by researchers in all climates, can be used to identify relevant weather fluctuations affecting the incidence of ARIs, and could help clarify the influence of contact rates on the spread of these diseases.

Magnetic phase diagram of CuO via high-resolution ultrasonic velocity measurements.

High-resolution ultrasonic velocity measurements have been used to determine the temperature-magnetic-field phase diagram of the monoclinic multiferroic CuO. A new transition at T(N3)=230 K, corresponding to an intermediate state between the antiferromagnetic noncollinear spiral phase observed below T(N2)=229.3 K and the paramagnetic phase, is revealed. Anomalies associated with a first order transition to the commensurate collinear phase are also observed at T(N1)=213 K. For fields with B || b, a spin-flop transition is detected between 11 T-13 T at lower temperatures. Moreover, our analysis using a Landau-type free energy clearly reveals the necessity for an incommensurate collinear phase between the spiral and the paramagnetic phase. This model is also relevant to the phase diagrams of other monoclinic multiferroic systems.

[Prevalence of negative stereotypes towards old age among personnel of a general hospital]. / Estereotipos negativos de la vejez en personal de salud de un Hospital de la Ciudad de Querétaro, México.

BACKGROUND: Social representations are value systems. Social stereotypes are a social consensus of traits associated with a specific group. Stereotypes about older subjects, generally have negative connotations. AIM: To assess the prevalence of negative stereotypes towards older subjects among health care personnel. MATERIAL AND METHODS: A questionnaire about stereotypes towards old age, with Likert type questions that included health, social motivations and personality-character domains, was applied to 52 doctors, 12 residents, 80 general nurses, 36 auxiliary nurses, four social workers and 10 medical assistants, working at a general hospital. RESULTS: The mean age of the professionals who answered the questionnaire was 38 years (95% confidence intervals (CI) 37-39 years) and 78% were women. The prevalence of a Global negative stereotype was 65.0%(95% CI: 59.5-70.5). The figure for the health domain was 64.5% (IC95%; 59.0-70.0), for the social motivation domain was 60%(5%CI: 54.3-65.7) and for the character personality domain was 64% (95%CI: 58.4-69.6).

El 11,1 por ciento de las pacientes desertaron del método al final del estudio. Se observó que el uso del desogestrel tuvo un valor estadísticamente significativo para el control de la dismenorrea (p<0,05) al final del cuarto trimestre de uso. Conclusión: Los implantes de desogestrel tienen efectos adversos importantes en los primeros meses de uso para disminuir la mayoría de ellos al final del primer año.
