[Correlation between consultation time and patient´s satisfaction in primary care]. / Correlación entre tiempo consulta y satisfacción del paciente en primer nivel de atención.

Background: It is important to understand how consultation time relates to patient satisfaction, as these two variables have not been extensively studied together. Objective: To determine the correlation between consultation time and patient satisfaction in primary care settings in Mexico. Materials and methods: Cross-sectional, observational, and analytical study that included patients over 18 years old. Time was measured using a stopwatch, and satisfaction was assessed using the Patient Doctor Relationship Questionnaire (PDRQ-9). The correlation between both variables was analyzed using the Spearman test, and multiple linear regression was employed to associate satisfaction with the consultation. Results: A total of 115 participants were included. The average consultation duration was 12.1 minutes, and 74% of patients reported that the consultation time was adequate. A weak positive correlation (p < 0.001, r = 0.38) was found between actual consultation time and satisfaction. Multiple linear regression demonstrated that for every minute increase in consultation time, level of satisfaction increased in 0.04 units (p = 0.001, CI95%: 0.016-0.063). Conclusion: Most patients reported satisfaction with the duration of their medical consultation, and longer consultation times were associated with higher satisfaction levels.

Introducción: es importante conocer cómo el tiempo de la consulta se relaciona con la satisfacción del paciente, ya que son dos variables que no se han estudiado a profundidad de forma conjunta. Objetivo: determinar la correlación que existe entre el tiempo de consulta y la satisfacción del paciente en un primer nivel de atención en México. Material y métodos: estudio transversal, observacional y analítico que incluyó a pacientes mayores de 18 años. Se midió el tiempo con cronómetro, así como la satisfacción mediante el cuestionario Patient Doctor Relationship Questionnaire (PDRQ-9). Se analizó la correlación entre ambas variables con la prueba de Spearman y para asociar la satisfacción con la consulta se empleó regresión lineal múltiple. Resultados: se incluyeron 115 participantes. La duración media de la consulta fue de 12.1 minutos y el 74% de los pacientes indicó que el tiempo de consulta les pareció adecuado. Se encontró una correlación positiva leve (p < 0.001, r = 0.38) entre el tiempo real de la consulta y la satisfacción. Mediante la regresión lineal múltiple se demostró que, por cada minuto de aumento en la consulta, el índice de satisfacción aumentaba en un 0.04 (p = 0.001, IC95%: 0.016-0.063). Conclusión: la mayoría de los pacientes refieren estar satisfechos con la duración de la consulta médica; sin embargo, a mayor duración de la consulta los pacientes muestran mayor satisfacción.

Monitoring of SARS-CoV-2 RNA in wastewater: A surveillance tool to foresee infection's evolution in the Mexican Caribbean.

The study aims to determine SARS-CoV-2 RNA in sewage of Cancun wastewater treatment plants, the main touristic destination of Mexico, and to estimate the infected persons during the sampling period. SARS-CoV-2 RNA traces were detected in the inlet of the five plants during almost all the sampling months. However, there is no presence of SARS-CoV-2 RNA traces in the effluent of the five WWTPs during the study period. ANOVA analysis showed differences in the concentrations of RNA traces of SARS-CoV-2 between the sample dates, but no differences were found from one WWTP to another. Estimated infected individuals by Markov chain Monte Carlo simulation are higher (between 77% and 91%) than the cases reported by the health authority. Wastewater monitoring and the estimation of infected individuals are a helpful tool, because estimation provides early warning signs on how broadly SARS-CoV-2 is circulating in the city, and led to the authorities to take measures wisely. PRACTITIONER POINTS: There is no presence of SARS-CoV-2 RNA traces in the effluent of the facilities, suggesting the effectiveness of treatment. Surveillance of viral RNA concentrations at treatment plants revealed presence in the influent of five plants Estimated infected individuals by MCMC simulation are higher than cases reported by health authority Environmental surveillance approach in wastewater influent is helpful to identify the clusters and to take informed decisions.

Angiotensin II Use in Treatment of Refractory Shock Due to Benazepril and Amlodipine Toxic Ingestion.

INTRODUCTION: Calcium channel blockers (CCB) are a leading cause of ingestion-associated fatality. Angiotensin-converting enzyme inhibitor (ACEi) overdose as part of co-ingestion is common and associated with refractory shock. Treatment options to manage this profound vasoplegia are limited. We describe the first case of use of newly formulated Angiotensin II for treatment of severe ACEi and CCB poisoning. CASE REPORT: A 57-year-old man presented after suicide attempt by ingesting 20 tablets each of amlodipine 10 mg and benazepril 20 mg. His hypotension was initially managed with 35 mL/kg of crystalloid, norepinephrine, and hyperinsulinemic euglycemic therapy (HIET). His hemodynamics further deteriorated, and he developed lactic acidosis, electrolyte derangements, and renal dysfunction. Further complications of his ingestion included cardiac arrest, subsequent requirement for emergency cricothyrotomy, and renal replacement therapy. Maximal hemodynamic support with HIET therapy insulin drip 4.4 units/kg/hour, norepinephrine 2 mcg/kg/min, epinephrine 1 mcg/kg/min, vasopressin .06 units/hour, and intravenous lipid emulsion was unsuccessful. Ang II was started and titrated to maximal doses with dramatic improvement in hemodynamics. Within hours of starting Ang II, epinephrine was stopped and norepinephrine decreased by 50%. He was downgraded from the intensive care unit without any ongoing end-organ dysfunction. DISCUSSION: Isolated CCB overdoses have high complication rates and well-established treatments. Therefore, management of CCB and ACEi co-ingestion is typically driven by CCB poisoning algorithm. There are multiple reports of CCB and ACEi co-ingestions causing treatment-refractory shock. Therapeutic options are limited by toxicities and availability of salvage therapies. Ang II is a safe and highly effective option to manage these patients.

Role of therapeutic inertia in glycemic control according to individualized objectives in a cohort of patients with type 2 diabetes. Results from CONCARDIA2.

BACKGROUND AND OBJECTIVE: Therapeutic inertia (TI) is the lack of initiation or intensification of treatment when indicated. It contributes to the fact that more than a third of people with type 2 diabetes mellitus (T2D) do not have adequate metabolic control. We set out to analyze the impact of TI during 4 years of follow-up in a cohort of T2D and its possible variables. MATERIALS AND METHODS: Prospective cohort study of a cohort of 297 TD2 patients. We considered TI when treatment was not modified during the 4 years, despite poor control. We contemplate uncontrolled those that did not meet their individualized HbA1c target. RESULTS: Uncontrolled patients: 87; age: 62.2 ±â€¯9.2; 58.7% men. We consider TI in 41.6% of the patients. Average HbA1c 8.22% in patients with treatment intensification of which 43.1% achieved their HbA1c goal, 29.8% were on monotherapy at the beginning, 29.8% double, 36.2% triple and 2,1% in quadruple therapy. There was more change in treatment in people with obesity (67.6 vs. 34.6%; P < 0.01) and the 6 of the study patients with cardiovascular events (P < 0.05). Metformin was part of the treatment in 97.1% of IT cases (vs. 76.6%; P < 0.01). Achievement of the HbA1c target was higher in patients receiving iSGLT2 (0 vs. 68.4%; P < 0.001). CONCLUSIONS: In 2 out of 5 uncontrolled T2D patients, the treatment was not changed; this was more evident in those patients treated with metformin. Patients with obesity and presence of cardiovascular events seem to protect against IT. Those who were on iSGLT2 have an advantage in meeting their HbA1c target.

ACTH-secreting parotid acinic cell carcinoma unusually reported as a paraneoplastic syndrome.

Paraneoplastic syndromes, induced by an immunological cross-reaction or hormone/peptide secretion, are an atypical presentation of tumors. Some tumors, such as small cell lung cancer and bronchial carcinoid, can be adrenocorticotropic hormone (ACTH) secreting tumors. Less commonly, parotid acinic cell carcinoma can be ACTH-secreting tumor leading to Cushing's syndrome. Few literature cases have described ACTH related paraneoplastic syndrome of parotid adenocarcinoma. Because of the rarity of the condition, little is known about the management and prognosis of this phenomenon. In this report, we highlighted the case of a 59-year-old male with a past medical history of parotid adenocarcinoma treated with surgery, chemotherapy, and radiation therapy presented with clinical and biochemical signs of hyperaldosteronism. Abdominal ultra-sound, computed tomography, and magnetic resonance imaging showed hepatic mass. Liver biopsy with immunohistochemistry confirmed the presence of parotid adenocarcinoma secreting ACTH. He is on paclitaxel and carboplatin medication with good clinical response.

Aplicación de los objetivos individualizados definidos por la guía europea 2019 de lípidos en pacientes con diabetes tipo 2 / Application of the individualized objectives defined by the European 2019 lipid guidelines in patients with type 2 diabetes

ANTECEDENTES Y OBJETIVO: La enfermedad cardiovascular supone una de las principales complicaciones de las personas con diabetes tipo 2 (DM2). La guía ESC/ESA 2019 de lípidos ha supuesto un cambio en el control de la dislipidemia. Analizamos la evolución del perfil lipídico, el cumplimiento de los objetivos de colesterol ligado a lipoproteínas de baja densidad (c-LDL), cómo clasifica a los pacientes y el impacto de esta guía en el control lipídico en pacientes con DM2. MATERIALES Y MÉTODOS: Estudio de cohortes prospectivo de 2017 a 2020 de una cohorte de 297 DM2 de un total de 1.229 (nivel de confianza del 95%). Clasificamos a los pacientes en función de su riesgo cardiovascular y si cumplían o no su objetivo de LDL. RESULTADOS: Edad 62,58±10,68 años; 52,79% varones. Niveles de c-LDL medio 116,2 al inicio y 100,2mg/dl a los 4 años (p<0,001). Cumplían su objetivo individualizado de c-LDL después de la publicación de la guía 57 (21,67%) pacientes. Hubo más controlados que eran menores de 65 años (57,9 vs. 36,9%; p<0,01; RR 0,83), varones (66,7 vs. 49,5%; p<0,05; RR 0,86) y fumadores (17,5 vs. 7,8%; p<0,05). El 74,23% tenía un riesgo cardiovascular alto y un objetivo c-LDL<70mg/dl. CONCLUSIONES: Desde la publicación de la guía de lípidos ESC/ESA 2019 se observa un descenso en los niveles de c-LDL. Aun así, solo uno de cada 5 pacientes cumple su objetivo individualizado de c-LDL. Presentaron ventajas por cumplir su objetivo los pacientes de sexo masculino, menores de 65 años y fumadores. La mayoría de los pacientes con DM2 tienen un riesgo cardiovascular alto y el objetivo de c-LDL predominante es inferior a 70mg/dl.

BACLGROUND AND OBJETIVE: Cardiovascular disease is one of the main complications of people with type 2 diabetes (T2D). The ESC/ESA 2019 lipid guide has led to a change in dyslipidemia control. We analyze the evolution of the lipid profile, the fulfillment of the low-density cholesterol (LDL-C) targets, how patients are classified and the impact of this guide on lipid control in T2D patients. MATERIALS AND METHODS: A prospective cohort study from 2017 to 2020 from a cohort of 297 T2D out of a total of 1229 (95% confidence level). We classified patients according to their cardiovascular risk and whether they met or not their LDL-C goal. RESULTS: Age 62.58±10.68 years; 52.79% men. Mean LDL-C levels 116.2 at baseline and 100.2mg/dL at 4 years (P<.001). They met their individualized LDL-C target after publication of the guide: 57 (21.67%). There were more controls who were under 65 years (57.9 vs. 36.9%; P<.01; RR 0.83), men (66.7 vs. 49.5%; P<.05; RR 0.86) and smokers (17.5 vs. 7.8%; P<.05). A percentage of 74.23 had a high cardiovascular risk and a target LDL-C<70mg/dL. CONCLUSIONS: Since the publication of the ESC/ESA 2019 lipid guide, a decrease in LDL-C levels has been observed. Only one in 5 patients fulfill their individualized LDL-C target. Male patients, under 65 years of age and smokers presented an advantage in meeting their goal. Most T2D patients have a high cardiovascular risk, and the predominant LDL-C target is less than 70mg/dL.

Cardiomyocytes disrupt pyrimidine biosynthesis in nonmyocytes to regulate heart repair.

Various populations of cells are recruited to the heart after cardiac injury, but little is known about whether cardiomyocytes directly regulate heart repair. Using a murine model of ischemic cardiac injury, we demonstrate that cardiomyocytes play a pivotal role in heart repair by regulating nucleotide metabolism and fates of nonmyocytes. Cardiac injury induced the expression of the ectonucleotidase ectonucleotide pyrophosphatase/phosphodiesterase 1 (ENPP1), which hydrolyzes extracellular ATP to form AMP. In response to AMP, cardiomyocytes released adenine and specific ribonucleosides that disrupted pyrimidine biosynthesis at the orotidine monophosphate (OMP) synthesis step and induced genotoxic stress and p53-mediated cell death of cycling nonmyocytes. As nonmyocytes are critical for heart repair, we showed that rescue of pyrimidine biosynthesis by administration of uridine or by genetic targeting of the ENPP1/AMP pathway enhanced repair after cardiac injury. We identified ENPP1 inhibitors using small molecule screening and showed that systemic administration of an ENPP1 inhibitor after heart injury rescued pyrimidine biosynthesis in nonmyocyte cells and augmented cardiac repair and postinfarct heart function. These observations demonstrate that the cardiac muscle cell regulates pyrimidine metabolism in nonmuscle cells by releasing adenine and specific nucleosides after heart injury and provide insight into how intercellular regulation of pyrimidine biosynthesis can be targeted and monitored for augmenting tissue repair.

Evolución del grado de control de una cohorte de pacientes anticoagulados de Atención Primaria / Evolution of the degree of control in a cohort of anticoagulated patients in Primary Care

Introducción: Solo el 60 por ciento de los pacientes en tratamiento con antagonistas de la vitamina K (AVK) están controlados. Objetivos: A nalizar una cohorte de pacientes anticoagulados para valorar su grado de control y su evolución a los 2 años, tras una intervención formativa breve. Métodos: Estudio longitudinal, observacional, retrospectivo de 157 anticoagulados con AVK. Se recogieron datos sociodemográficos, comorbilidades, motivo de prescripción del AVK y grado de control basal y tras 2 años de seguimiento. Utilizamos 2 métodos de valoración diferentes: Rosendaal y método directo (porcentaje de INR-Razón Normalizada Internacional- en rango). Asimismo, establecimos correlaciones temporales intramétodo. Resultados: El grado de control pasó del 47,3 por ciento al 53,5 por ciento a los 2 años, según Rosendaal (p= 0,52), y del 39,5 por ciento al 53,5 por ciento según el método directo (p< 0,05). El tiempo en rango terapéutico fue del 63,1 ±19,9 por ciento al inicio y 65 ±19,2 por ciento al final del seguimiento. La correlación entre los 2 controles fue positiva para ambos métodos (Rosendaal: 0,23; método directo: 0,33). El análisis multivariante fue significativo para el sexo masculino y para un objetivo diferente de 2,5-3,5 (odds ratio: 2,22 y 2,73, respectivamente). Conclusiones: El control del INR mejoró a los 2 años de seguimiento tras la actividad formativa. La evolución del grado de control de cada paciente es parcialmente predecible. El peor control se asoció al sexo femenino y al objetivo de INR de 2,5-3,5. El control mejora 2,22 veces en los varones y 2,73 veces en quienes no tienen un INR objetivo de 2,5-3,5(AU)

Introduction: Only 60 percent of patients on treatment with vitamin K antagonists (AVK) are controlled. Objectives: We proposed to analyze a cohort of anticoagulated patients to assess their degree of control and their evolution at 2 years, after a brief training intervention. Methods: Longitudinal, observational, retrospective study of 157 anticoagulated with AVK. Sociodemographic data, comorbidities, reason for VKA prescription and degree of baseline control were collected and after 2 years of follow-up. We use 2 different valuation methods: Rosendaal and direct method (INR percentage -International Normalized Ratio- in range). Likewise, we established intra-method temporal correlations. Results: The degree of control went from 47.3 percent to 53.5 percent at 2 years, according to Rosendaal (p = 0.52), and from 39.5 percent to 53.5 percent according to the direct method (p<0.05). The time in the therapeutic range was 63.1±19.9 percent at the start and 65±19.2 percent at the end of the follow-up. The correlation between the 2 controls was positive for both methods (Rosendaal: 0.23; direct method:0.33). The multivariate analysis was significant for males and for a target other than 2.5-3.5(odds ratio: 2.22 and 2.73, respectively). Conclusions: INR control improved after 2 years of follow-up after training activity. The evolution of the degree of control of each patient is partially predictable. The worst control was associated with female sex and the INR goal of 2.5-3.5. Control improves 2.22 times in males and 2.73 times in those without a target INR of 2.5-3.5(AU)

Mortalidad en una cohorte de pacientes de Atención Primaria tratados con anticoagulantes antagonistas de la vitamina K / Mortality in a cohort of primary care patients treated with vitamin K antagonist anticoagulants

Introducción y objetivos: El uso de anticoagulantes para prevenir eventos embólicos en España es muy elevado, tendiendo a un aumento progresivo. Por ello pretendemos analizar la mortalidad de los pacientes tratados con anticoagulantes antagonistas de la vitamina K (AVK) de un área metropolitana de Granada, en 2 años no consecutivos.Pacientes y métodos: Estudio longitudinal, observacional, retrospectivo de 205 pacientes tratados con AVK. Se recogieron datos sociodemográficos, condiciones clínicas previas, patología causante del tratamiento AVK, grado de control y la mortalidad a 2 años del inicio del estudio.ResultadosEdad media, 76±11,8años (57,56% mujeres). La mortalidad a los 2 años fue del 22,4%, con un aumento significativo en función de la edad (p<0,001) y los años de tratamiento (p<0,001). Los pacientes con demencia (p<0,05), con enfermedad renal crónica (p<0,01) o con enfermedad pulmonar obstructiva crónica (p<0,01) presentaron también mayor mortalidad. El análisis multivariante demostró efecto significativo de la enfermedad renal crónica (odds ratio=4,075), la enfermedad pulmonar obstructiva crónica (odds ratio=3,694) y los años de tratamiento (odds ratio=1,236).ConclusionesA los 2 años de seguimiento, fallecieron uno de cada 5 pacientes tratados con AVK y se asociaron independientemente a este aumento la presencia de enfermedad renal crónica, enfermedad pulmonar obstructiva crónica y un mayor tiempo de tratamiento. La mayoría de los pacientes estaban anticoagulados por una fibrilación auricular, tenían una edad avanzada y una alta prevalencia de comorbilidades. (AU)

Introduction and objectives: The use of anticoagulants to prevent embolic events in Spain is very high, tending to a progressive increase. For this reason, we intend to analyse the mortality of patients from a metropolitan area of Granada treated with vitamin K antagonist anticoagulants (VKA), over 2 non-consecutive years.Patients and methods: Longitudinal, observational, retrospective study of 205 patients treated with VKA. Sociodemographic data, previous clinical conditions, pathology causing VKA treatment, degree of control and mortality were collected 2 years after the start of the study.ResultsAverage age, 76±11.8 years (57.56% women). Two-year mortality was 22.4%, with a significant increase depending on age (p<.001) and years of treatment (p<.001). Patients with dementia (p<.05), with chronic kidney disease (p<.01) or with chronic obstructive pulmonary disease (p<.01) also presented higher mortality. Multivariate analysis showed significant effect of chronic kidney disease (odds ratio=4.075), chronic obstructive pulmonary disease (odds ratio=3.694), and years of treatment (odds ratio=1.236).ConclusionsAt 2 years of follow-up, 1 in 5 patients treated with VKA died. The presence of chronic kidney disease, chronic obstructive pulmonary disease and a longer treatment time were independently associated with this increase of mortality. Most of the patients were anticoagulated by atrial fibrillation, they were elderly and had a high prevalence of comorbidities. (AU)

Effect of different inspired fractions of oxygen on F-shunt and arterial partial pressure of oxygen in isoflurane-anaesthetized and mechanically ventilated Shetland ponies.

OBJECTIVE: To determine the effect of fraction of inspired oxygen (FiO2) on intrapulmonary shunt fraction as measured by F-shunt in ponies during isoflurane anaesthesia. STUDY DESIGN: Prospective, randomized clinical study. ANIMALS: A group of 23 adult Shetland ponies undergoing a total of 32 anaesthetic procedures. METHODS: Ponies were premedicated intravenously (IV) with detomidine (0.01 mg kg-1) and either morphine (0.1 mg kg-1) or butorphanol (0.02 mg kg-1). Anaesthesia was induced with ketamine (2.2 mg kg-1) and midazolam (0.07 mg kg-1) administered IV. Ponies were randomly allocated to maintenance of anaesthesia with isoflurane in oxygen (group TH; FiO2 = 0.95) or a mixture of oxygen and medical air (group TL; FiO2 = 0.65); all ponies were given a constant rate of infusion of detomidine. Animals were mechanically ventilated to maintain PaCO2 between 40 and 50 mmHg. Arterial blood gas analysis was performed every 30 minutes. The F-shunt equation was calculated for each time point T0, T30, T60 and T90. Data were analysed using linear mixed model analysis and presented as mean ± standard deviation (p < 0.05). RESULTS: PaO2 was greater in group TH than in group TL (TH: 406 ± 90, 438 ± 83, 441 ± 69 and 464 ± 53 mmHg versus TL: 202 ± 90, 186 ± 84, 172 ± 85 and 191 ± 98 mmHg at T0, T30, T60 and T90, respectively; p < 0.0001). In TH, F-shunt was < TL. Significant differences were found at T60 (TH: 13.2% ± 4.3 versus TL: 19.4% ± 8.3; p = 0.016) and T90 (TH: 11.7% ± 3.5 versus TL: 18.6% ± 9.5; p = 0.036). CONCLUSIONS AND CLINICAL RELEVANCE: Our findings do not support a beneficial effect of using a reduced FiO2 to improve oxygenation in anaesthetized and mechanically ventilated Shetland ponies.

Agreement between invasive and oscillometric arterial blood pressure measurement using a high-definition oscillometric device in normotensive New Zealand White rabbits using two different anaesthetic protocols.

OBJECTIVE: To use American College of Veterinary Internal Medicine (ACVIM) criteria to evaluate a high-definition oscillometric (HDO) blood pressure monitoring device versus invasive blood pressure (IBP) measurement in normotensive rabbits anaesthetized with two different anaesthetic protocols. STUDY DESIGN: Prospective experimental study. ANIMALS: A group of 20 healthy adult New Zealand White rabbits weighing 4.36 ± 0.37 kg (mean ± standard deviation). MATERIALS AND METHODS: Rabbits were premedicated with butorphanol 0.5 mg kg-1 and midazolam 0.5 mg kg-1 subcutaneously (SC, group BMA) or ketamine 25 mg kg-1 and medetomidine 0.4 mg kg-1 SC (group KM). Anaesthesia was induced with alfaxalone administered intravenously (group BMA) or isoflurane by face mask (group KM) and maintained with isoflurane in oxygen. IBP was measured from the central auricular artery. The cuff for the HDO monitor was placed distal to the left elbow and distal to the left tarsus. Agreement between invasive and HDO measurements was evaluated using Bland-Altman method. RESULTS: In group KM there was better agreement between the HDO device and IBP when the cuff was placed on the thoracic limb, with 100% and 91% of the readings for mean (MAP) and diastolic arterial pressure (DAP), respectively, within 10 mmHg of the IBP measurements. The agreement, although worse, also met the ACVIM criteria for systolic arterial pressure (SAP; 53% of the readings within 10 mmHg). In group BMA, the device met the criteria with the cuff on the thoracic limb only, and only for MAP and DAP (73% and 75% of the measurements within 10 mmHg of the IBP, respectively) but not for SAP (12%). CONCLUSION AND CLINICAL RELEVANCE: The HDO device met most of the ACVIM criteria for noninvasive blood pressure measurement in anaesthetized rabbits, specifically when the cuff was placed distal to the elbow and the anaesthetic protocol included ketamine and medetomidine.

Candidiasis y Candida albicans / Candidiasis and Candida albicans

La candidiasis es una enfermedad micótica debida a levaduras pertenecientes al género Candida. Dentro del gran conjunto de microorganismos que colonizan al ser humano, Candida albicans es el agente etiológico más comúnmente detectado ya que habita como comensal en las superficies mucosas y la piel. C. albicans participa en procesos de fermentación de azúcares y asimilación de nutrientes, pero, en algunas ocasiones se relaciona con procesos patológicos. En los últimos años los avances tecnológicos y médicos; así como el aumento en la incidencia de infecciones por el virus de la inmunodeficiencia humana, el auge creciente de la terapia inmunomoduladora y el uso de antibióticos de amplio espectro durante largos períodos de tiempo se han convertido en los factores de riesgo más importantes para la creciente incidencia de infecciones por microorganismos del género Candida. Debido a esto, resulta imperativo el conocimiento de esta enfermedad y sus formas clínicas más importantes, así como el abordaje diagnóstico y el tratamiento actual; información que recolectamos en este documento para brindar una visión general sobre esta patología(AU)

Candidiasis is a fungal disease caused by yeasts belonging to the genus Candida. Within the large group of microorganisms that colonize humans, candida albicans is the most commonly detected etiological agent since it inhabits mucosal surfaces and skin as a commensal. C. albicans participates in sugar fermentation processes and assimilation of nutrients but, on some occasions, it is related to pathological processes. In recent years, technological and medical advances; As well as the increase in the incidence of human immunodeficiency virus infections, the growing boom in immunomodulatory therapy and the use of broad-spectrum antibiotics for long periods of time have become the most important risk factors for the increasing incidence of infections by microorganisms of the genus Candida. Due to this, knowledge of this disease and its most important clinical forms, as well as the current diagnostic approach and treatment, is imperative; information that we collect in this document to provide an overview of this condition(AU)

Type V Collagen in Scar Tissue Regulates the Size of Scar after Heart Injury.

Scar tissue size following myocardial infarction is an independent predictor of cardiovascular outcomes, yet little is known about factors regulating scar size. We demonstrate that collagen V, a minor constituent of heart scars, regulates the size of heart scars after ischemic injury. Depletion of collagen V led to a paradoxical increase in post-infarction scar size with worsening of heart function. A systems genetics approach across 100 in-bred strains of mice demonstrated that collagen V is a critical driver of postinjury heart function. We show that collagen V deficiency alters the mechanical properties of scar tissue, and altered reciprocal feedback between matrix and cells induces expression of mechanosensitive integrins that drive fibroblast activation and increase scar size. Cilengitide, an inhibitor of specific integrins, rescues the phenotype of increased post-injury scarring in collagen-V-deficient mice. These observations demonstrate that collagen V regulates scar size in an integrin-dependent manner.

Introduction: Aspiration pneumonia is a subclass of community-acquired pneumonia that is expected to have an increasing contribution in mortality and morbidity, particularly in the elderly population over the next coming decades. While studies have revealed significant progress in identifying risk factors for aspiration pneumonia, the clinical presentation and diagnosis remain challenging to healthcare providers. Areas covered: We conducted a broad literature review using the MeSH heading in PubMed/MEDLINE of 'aspiration pneumonia' from January 1970 to July 2019. The understanding of the microbiology of aspiration pneumonia has evolved from a possible shift in the causative organisms away from anaerobes to traditional community-acquired pneumonia organisms. The importance of this shift is not yet known, but it has questioned the pathogenic role of anaerobes, appropriate anaerobic testing and the role of these pathogens in the pulmonary microbiome in patients with pneumonia. The identification of risk factors led to strategies to prevent or minimize the risk of aspiration pneumonia with moderate success. Expert opinion: Our expert opinion is that further research is needed to determine the role of the microbiome with aspiration pneumonia and patient risk factors. There is also a great need to develop clinical tools to help providers diagnose, treat, and prevent aspiration pneumonia.

Análisis de las características de las ponencias y ponentes de los 29 congresos de la Sociedad Española de Medicina de Urgencias y Emergencias -SEMES- (1988-2017) / Presentations at 29 conferences of the Spanish Society of Emergency Medicine (SEMES) from 1988 to 2017: a descriptive analysis

Objetivo. Profundizar en el conocimiento y la evolución de la Medicina de Urgencias y Emergencias (MUE) en España a través del análisis de las ponencias presentadas en los congresos de la Sociedad Española de Medicina de Urgencias y Emergencias (SEMES) celebrados los últimos 30 años (1988-2017). Método. Se revisaron los programas de todos los Congresos SEMES y se analizaron las características de ponencias y ponentes, así como la evolución entre 1988-2017 de algunas de estas características. Se revisó en Web of Science la producción científica y el índice h de los ponentes más frecuentes para contrastar su relevancia científica. Resultados. En los 29 Congresos SEMES (en 1992 no se celebró) se han presentado 2.182 ponencias (112 internacionales) por 1.410 ponentes (89 internacionales) procedentes de 616 centros. Hubo un crecimiento lineal de ponencias y ponentes los primeros años, una posterior fase de meseta, y finalmente un crecimiento con tendencia exponencial el último lustro. El 79,6% de ponencias fue impartida por hombres, y la distribución de médicos/enfermeros/técnicos fue 70,6%/11,9%/4,0%. Los urgenciólogos realizaron el 60,8% de ponencias médicas. La comunidad autónoma organizadora del congreso aportó el 29,8% de ponencias, casi siempre por encima de lo esperable por su aportación promedio global. Hubo comunidades autónomas cuya participación estuvo muy por debajo de su productividad científica (Extremadura, Andalucía, Cataluña) y otras muy por encima (Murcia, Baleares, Asturias, Castilla-León, Madrid). El 64,4% de los 59 ponentes más asiduos ( 5 congresos) tiene publicados 20 artículos y el 71,2% tiene un índice h 5. Entre 1988-2017 hubo incremento significativo de mujeres ponentes, diversificación geográfica (ponencias de comunidades autónomas no organizadoras del congreso) y urgenciólogos hospitalarios. Conclusiones. Hubo un aumento significativo de ponencias y ponentes en los Congresos SEMES, con cambios detectables en algunas de sus características. El análisis detallado puede permitir intervenciones para corregir algunos aspectos en futuros Congresos SEMES, tales como la escasa diversificación y participación internacional y de mujeres

Objective. To gain greater understanding of the development of emergency medicine in Spain by analyzing the presentations at conferences of the Spanish Society of Emergency Medicine (SEMES) over the past 30 years (1988-2017). Methods. We examined the programs of all SEMES conferences and described the characteristics of both presentations and presenters. We also analyzed changes occurring between 1988 and 2017 of some of the characteristics observed. The Web of Science was searched to evaluate the scientific productivity of the most frequent presenters and to calculate h-indexes for those presenters to assesstheir scientific relevance. Results. SEMES did not hold a conference in 1992. The total of 29 conferences included 2182 presentations (112 listing presenters from abroad) given by 1410 presenters (89 from abroad). The presenters' affiliations named 616 centers. The number of presentations and presenters increased linearly during the first period and then leveled off. The number increased exponentially in the final phase. Men gave 79.6% of the presentations; 70.6% of the presenters were physicians, 11.9% were nurses and 4.0% were ambulance staff. Specialists in emergency medicine accounted for 60.8% of the presenters who were physicians. Presenters from the Spanish autonomous community organizing the conference gave 29.8% of the presentations. The contributions of presenters from the local organizing community were nearly always more numerous than the average number of contributions from that community in all 29 conferences overall. Conference contributions from some autonomous communities (Extremadura, Andalusia, and Catalonia) were considerably fewer than would be expected given the scientific productivity of those communities. However, communities (Murcia, Balearic Islands, Asturias, Castile-Leon, Madrid), gave many more presentations than their productivity metrics would predict. Analysis of the 59 most frequent presenters (at 5 conferences or more) showed that 64.4% of them had published at least 20 articles and that 71.2% had an h-index of 5 or higher. The number of women on the program increased significantly between 1988 and 2017. Likewise, geographic diversity increased significantly (presentations from centers outside the local organizing area) as did the participation of hospitalbased emergency medicine specialists. Conclusions. SEMES conference programs have attracted significantly more presentations and presenters over the years. We also detected changes in descriptive characteristics. The analysis of those characteristics can help future SEMES conference planners to plan ways to correct aspects such as scarce geographic diversity, low international participation, and few women among presenters
