Hallazgo renal infrecuente en una paciente con anemia y pérdida de peso / Unexpected kidney finding in a patient with anemia and weight loss

Mujer de 57 años con trastorno del espectro autista y crisis epilépticas secundarias que consulta por clínica debida a anemia y pérdida de peso. Como antecedentes más relevantes destaca un ingreso hospitalario por sepsis urinaria, donde se evidenció Morganella morganii y una bacteriemia con aislamiento de Staphylococcus epidermidis. La paciente no refería en el momento de la consulta clínica urinaria.Se realizó un TC de abdomen donde se observa un aumento de tamaño del riñón derecho, con pérdida de la diferenciación córtico-medular y sustitución del parénquima renal normal por masas de baja atenuación en el espesor de un parénquima renal destruido que se corresponden con los cálices dilatados. Todo ello asociado a un cálculo coraliforme con afectación de la grasa peripélvica.(AU)

57-year-old woman with autism spectrum disorder and secondary epileptic seizures. A CT of abdomen is requested due to anemia and weight loss. The patient did not refer urinary symptoms. She was admitted four months to Internal Medicine Service, due to urinary sepsis, where Morganela morgani was isolated, and bacteremia, with Staphylococcus epidermidis isolation.In the CT performed, we found an increase in the size of the right kidney, with loss of corticomedullary differentiation and replacement of a destroyed renal parenchyma by low-attenuation masses that corresponds to the dilated calyces. A staghorn stone with involvement of the peripelvic fat was also described.(AU)

Evaluación del perfil de seguridad del medicamento lopinavir/ritonavir (Lpv/r) en los pacientes sospechosos o confirmados por COVID-19 / Evaluation of the safety profile of the drug lopinavir/ritonavir (Lpv/r) in suspected or confirmed COVID-19 patients

Introducción: El nuevo SARS-CoV-2, es el agente causal de la enfermedad COVID-19. La Organización Mundial de la Salud (OMS) ha referenciado el uso del lopinavir/ritonavir (Lpv/r), es un inhibidor de la proteasa del virus de inmunodeficiencia humana adquirida (VIH-1). El estudio clínico de Cao et al., identificó que el uso de Lpv/r no se asociaron con un mayor número de eventos adversos en comparación con el tratamiento estándar.Materiales y métodos: Estudio retrospectivo de farmacovigilancia en una cohorte en pacientes sospechosos o confirmados de COVID-19 en un hospital de tercer Nivel de la Ciudad de México en el periodo 01 abril 2020 al 30 julio 2020. Resultados: El tratamiento de Lpv/r incluyó 140 pacientes, de los cuales 91 pacientes completaron el tratamiento, mientras que 50 pacientes no terminaron el esquema. Los principales motivos de la suspensión del esquema del medicamento fueron: alta por mejoría (11 casos), defunciones (10 casos) y por inicio de ruxolitinib (9 casos). Además, se identificaron 8 reacciones adversas al medicamento, de las cuales 5 son reacciones asociadas a los trastornos gastrointestinales (diarreas) y las otras 3 reacciones asociadas a trastornos hepatobiliares (hipertransaminasemia).Conclusión: El perfil de seguridad del medicamento Lpv/r demostró una coherencia con las observaciones de estudios previos en relación en los eventos adversos presentados de tipo gastrointestinales y hepáticos, estos últimos se encuentran relacionados a interacción fármaco-fármaco, por lo que sugerimos un seguimiento farmacoterapéutico para identificar las interacciones y las reacciones adversas durante el uso Lpv/r.

Abstract: The new SARS-CoV-2 is the causal agent for COVID-19. The World Health Organization (WHO) referenced the use of lopinavir/ritonavir (Lpv/r), which is a protease inhibitor of human inmunodeficiency virus (HIV-1). The Clinical trial by Cao et al. identified that the use of Lpv/r has not been associated with any increase of adverse drug reactions within compared to the standard of care.Materials and methods: Pharmacovigilance retrospective study of patients suspected or confirmed with COVID-19 in a 3rd level hospital in Mexico City from April, 01 2020 to July, 30 2020.Results: Lopinavir/ritonavir treatment was prescribed 140 patients from which 91 patients completed the treatment, while 50 patients did not completed the treatment. The cause suspensions were: patient discharge for improvement (11 cases), deaths (10 cases) and start of ruxolitinib (9 cases). In addition, were identify 8 adverse drug reaction from which 5 were associated to gastrointestinal disorders (diarrhea) and 3 hepatobiliary disorders (hypertransaminasemia).Conclusion: The safety profile of the Lpv/r demonstrated consistency with the observations of previous studies in relation to gastrointestinal and hepatic adverse events, which were related to drug-drug interaction, so we suggest a pharmacotherapeutic monitoring to identify them as well as adverse drug reactions due to Lpv/r.

Infección por SARS-CoV-2 y seroprevalencia en pacientes con esclerosis múltiple / SARS-CoV-2 infection and seroprevalence in patients with multiple sclerosis

Introducción: El efecto de la infección por SARS-CoV-2 en los pacientes con esclerosis múltiple (EM) y la influencia de los tratamientos modificadores de la enfermedad (TME) es desconocida. Hasta el momento no se ha observado que los pacientes con EM tengan mayor riesgo de infección por COVID-19, ni peor curso evolutivo de la misma.MétodosEstudio descriptivo de pacientes con EM e infección por SARS-CoV-2 diagnosticada mediante PCR. Hemos analizado variables demográficas, clínicas, de laboratorio y de tratamiento en nuestra muestra. Se ha determinado la presencia de anticuerpos frente a SARS-CoV-2 en estos pacientes.ResultadosLa forma de esclerosis múltiple remitente recurrente (EMRR) fue la más frecuente en lo pacientes con EM e infección por COVID-19. El 10,2% presentó una evolución desfavorable, relacionada con una mayor edad y una Expanded Disability Status Scale (EDSS) más elevada. La seroprevalencia de anticuerpos frente a SARS-CoV-2 en nuestro estudio ha sido del 83,3%. El desarrollo de anticuerpos no está relacionado con el TME, la presencia de linfopenia u otros factores analizados.ConclusionesLa incidencia de COVID-19 ha sido ligeramente inferior a la de la población general de nuestra provincia. La evolución desfavorable se ha relacionado con una mayor edad y una puntuación elevada en la EDSS. El TME y la linfopenia no se han relacionado con el curso de la infección por COVID-19. La seroprevalencia es similar a la encontrada en población general con PCR positiva, sin poder determinar la influencia de los distintos TME. (AU)

Introduction: The effect of SARS-CoV-2 infection in patients with multiple sclerosis (MS) and the influence of disease-modifying therapies (DMT) for MS on COVID-19 are unknown. To date, patients with MS have not been shown to present greater risk of COVID-19 or more severe progression of the disease.MethodsWe performed a descriptive study of patients with MS presenting SARS-CoV-2 infection diagnosed with PCR. We analysed demographic, clinical, laboratory, and treatment variables in our sample. Presence of antibodies against the virus was also determined.ResultsRelapsing-remitting MS (RRMS) was the most frequent form of MS in our sample. Prognosis was unfavourable in 10.2% of patients, and was associated with older age and higher scores on the Expanded Disability Status Scale (EDSS). Seroprevalence of antibodies against SARS-CoV-2 was 83.3% in our sample. Development of antibodies was not associated with DMT, lymphocytopaenia, or any of the other variables analysed.ConclusionsThe incidence of COVID-19 was slightly lower in our sample than in the general population in our province. Unfavourable prognosis was associated with older age and higher EDSS scores. DMT and lymphocytopaenia did not influence the clinical course of COVID-19. Seroprevalence of antibodies against the virus in our sample was similar to that reported for the general population with positive PCR results for the virus; the influence of specific DMTs could not be determined.

Nutrient content and stoichiometry of pelagic Sargassum reflects increasing nitrogen availability in the Atlantic Basin.

The pelagic brown macroalgae Sargassum spp. have grown for centuries in oligotrophic waters of the North Atlantic Ocean supported by natural nutrient sources, such as excretions from associated fishes and invertebrates, upwelling, and N2 fixation. Using a unique historical baseline, we show that since the 1980s the tissue %N of Sargassum spp. has increased by 35%, while %P has decreased by 44%, resulting in a 111% increase in the N:P ratio (13:1 to 28:1) and increased P limitation. The highest %N and δ15N values occurred in coastal waters influenced by N-rich terrestrial runoff, while lower C:N and C:P ratios occurred in winter and spring during peak river discharges. These findings suggest that increased N availability is supporting blooms of Sargassum and turning a critical nursery habitat into harmful algal blooms with catastrophic impacts on coastal ecosystems, economies, and human health.

[Diagnostic agreement of primary care and minor surgery in a basic health area]. / Concordancia diagnóstica entre atención primaria y cirugía menor en una zona básica de salud.

AIM: Minor Surgery (MS) is an ever-increasing programmed activity in Primary Health Care Centres (PHC). The aim of this study is to establish the clinical and histopathology diagnostic agreement between PHC and MS and evaluating the efficacy of this activity. METHODS AND MATERIALS: A retrospective, observational, and reliability study was performed. A total of 234 patient specimens were sent to Histopathology between January 2014 and December 2018 in basic health area of San Benito-La Laguna, Santa Cruz de Tenerife. Of these, 203 specimens met criteria, with 31 being excluded due to death or absence of diagnosis. Sociodemographic and diagnostic variables were analysed, and 10 possible diagnoses were grouped into 3 categories according to their nature. Cohen kappa coefficient was used as the main evaluation measure. RESULTS: The majority of specimens were obtained from women (51.2%), and the mean age was 52.82±17.82 years. The most frequently referred lesion was the epidermoid cyst (20.2-21.67%). A clinical-pathological agreement of 60% was obtained in Minor Surgery, with a specificity of 98.3% and a sensitivity of 61.9%. In Primary Care agreement was 36.1%, with a specificity of 98.4% and a sensitivity of 42.8%. Infectious lesions represented the largest concordance difference obtained, with 27% less in Primary Care compared to Minor Surgery. CONCLUSIONS: Minor Surgery is an effective support in the initial diagnosis of lesions referred for evaluation at Primary Care. However, it is necessary to implement improvements in diagnostic efficacy of Primary Care.

Two thalidomide analogs induce persistent estrous behavior and inhibit uterus contractility in rats: The central role of cAMP.

The effects of 4NO2PDPMe and 4APDPMe, which are thalidomide (Tha) analogs that act as selective phosphodiesterase (PDE-4) inhibitors, on estrous behavior (lordosis and proceptive behaviors) and on uterine contraction were studied in ovariectomized (OVX) estrogen-primed Sprague Dawley (SD) and in intact non-pregnant Wistar rats, respectively. We found that intracerebroventricular (ICV) infusion of either 4NO2PDPMe or 4APDPMe (20 to 80 µg) stimulated intense lordosis and proceptive behavior in response to mounts from a sexually active male, within the first 4 h after infusion, and persisting for up to 24 h. Inhibitors of the progesterone receptor (RU486, administered subcutaneously), the estrogen receptor (tamoxifen, ICV), the adenylate cyclase (AC)/ cyclic AMP (cAMP)/protein kinase A (PKA) pathway (administered ICV), and the mitogen activated protein kinase (MAPK) pathway (administered ICV) significantly decreased lordosis and proceptive behavior induced by Tha analogs. Uterine contractility studies showed that Tha analogs inhibited both the K+- and the Ca2+-induced tonic contractions in rat uterus. Tha analogs were equally effective, but 4APDPMe was more potent than 4NO2PDPMe. These results strongly suggest the central role of cAMP in both processes, sexual behavior, and uterine relaxation, and suggest that Tha analogs may also act as Ca2+-channel blockers.

Respuesta familiar ante la revelación de la orientación sexual, desde el discurso de hombres homosexuales / Family response to the revelation of the sexual orientation, from the discourse of homosexual men / Resposta familiar perante à revelação da orientação sexual, desde o discurso de homens homossexuais

Resumen Introducción La homosexualidad representa fragmentar las normas establecidas socialmente, provenientes de una sociedad sectorizada, que adopta un patrón de obligatoriedad heteronormativa, por lo que una orientación sexual disidente conlleva enfrentar un sinfín de prejuicios, con afecciones significativas en el entorno familiar. Objetivo Conocer la respuesta del entorno familiar ante la revelación de la orientación sexual, desde el discurso de hombres homosexuales. Métodos Estudio cualitativo descriptivo, en el que se realizaron entrevistas semiestructuradas y observación participante a cinco hombres homosexuales de 19 a 36 años de edad de la ciudad de Puebla, México, a través de un muestreo teórico y el empleo de participantes clave para el acceso a los informantes. Resultados Los hallazgos se estructuraron en torno a una categoría central: respuesta familiar ante un integrante homosexual, de la cual se desprenden tres subcategorías: creencia familiar, conflicto familiar y proceso de pérdida familiar a la heteronormatividad, la cual se encuentra integrada por la agrupación de múltiples códigos, clasificados de acuerdo a las cinco etapas del proceso de pérdida, propuestas por Kübler-Ross. Discusión Las respuestas familiares ante la homosexualidad son dinámicas, sumergidas en un proceso de negación que con el tiempo puede llegar a la aceptación. Conclusiones Las respuestas familiares desencadenadas por la homosexualidad se expresan de forma multifacética y a manera de proceso; el conocimiento de éstas puede ayudar a guiar el actuar de enfermería y del equipo de salud, para planear actividades y estrategias ante el proceso de pérdida familiar de la heteronormatividad.

Abstract Introduction Homosexuality represents a deviation from the social norms established by a sectorial society which imposes having a mandatory heterosexual pattern. Because of this, having a different sexual orientation implies facing prejudices which have diverse impacts on the family environment. Objective To know the response of the family environment towards the revelation of the sexual orientation from the perspective of homosexual males. Methods This is a qualitative and descriptive study with theoretical sampling and key informing, which used semi-structured interviews and observations on five homosexual males from the city of Puebla, Mexico, whose ages ranged from 19 to 36 years old. Results: The findings clustered around a central category: the family response towards having a homosexual member, from which three subcategories emerged: family beliefs, family conflict, and the loss of the heterosexual normativity, reflected by multiple codes classified in the five stages of the process of a loss proposed by Kübler-Ross. Discussion: The family responses towards homosexuality are dynamic and framed by a denial process which eventually can lead to the acceptance. Conclusions: The family responses towards having a member being homosexual are multiple; thus, an understanding of these responses can help nurses and other health professionals to plan activities and strategies aimed at addressing the process of the family loss of the heterosexual normativity.

Activation energy for the viscoelastic flow: Analysis of the microstructure-at-rest of (water- and milk-based) fruit beverages.

Fresh fruit beverages are a tasty way to follow the recommendations of World Health Organization. A study on the rheological behaviour of water-based and milk-based fruit beverages with emphasis on the temperature effect was made. The power law model adjusted data of apparent viscosity. The flow index of each beverage was practically constant with temperature variation. Then, one could discuss the variation with temperature of the consistency index. This parameter decreased around 40% in both cases in the temperature interval 5-30 °C. The stability of beverages against the sedimentation of the fruit pulp was clearly affected by the increase of temperature. Viscoelastic moduli were obtained in the linear region. Temperature dependency of both moduli was described in the interval 5-30 °C. The activation energy for linear viscoelastic flow was slightly higher than the activation energy for viscous flow. This result was interpreted as an indication of the strength of the microstructure-at-rest.

First clinical symptom as a prognostic factor in systemic sclerosis: results of a retrospective nationwide cohort study.

The objective of the study is to determine the importance of the mode of onset as prognostic factor in systemic sclerosis (SSc). Data were collected from the Spanish Scleroderma Registry (RESCLE), a nationwide retrospective multicenter database created in 2006. As first symptom, we included Raynaud's phenomenon (RP), cutaneous sclerosis, arthralgia/arthritis, puffy hands, interstitial lung disease (ILD), pulmonary arterial hypertension (PAH), and digestive hypomotility. A total of 1625 patients were recruited. One thousand three hundred forty-two patients (83%) presented with RP as first symptom and 283 patients (17%) did not. Survival from first symptom in those patients with RP mode of onset was higher at any time than those with onset as non-Raynaud's phenomenon: 97 vs. 90% at 5 years, 93 vs. 82% at 10 years, 83 vs. 62% at 20 years, and 71 vs. 50% at 30 years (p < 0.001). In multivariate analysis, factors related to mortality were older age at onset, male gender, dcSSc subset, ILD, PAH, scleroderma renal crisis (SRC), heart involvement, and the mode of onset with non-Raynaud's phenomenon, especially in the form of puffy hands or pulmonary involvement. The mode of onset should be considered an independent prognostic factor in systemic sclerosis and, in particular, patients who initially present with non-Raynaud's phenomenon may be considered of poor prognosis.
