Metástasis pulmonar y pleural en cáncer de pene, una patología infrecuente

Introduction: Carcinoma of the penis is a rare tumor in our environment, constituting less than 1% of deaths in men and it is defined as the proliferative disordered process of squamous epithelial cells of the penis. Objective: The objective of the following manuscript is to present the case of a patient who developed cancer of the penis with metastasis to the lung. Clinical case: An 85-year-old patient was admitted due to a 24-hour clinical picture consisting of hematuria associated with non-productive cough, low back pain, asthenia and adynamia. He had a history of squamous cell carcinoma of the penis, he was identified as a heavy smoker until two years ago and presented chronic exposure to wood smoke. On the physical examination, the patient evidenced a regular general state, respiratory sounds that suggested left hypoventilation, absence of penis due to his clinical history and outflow of hematuric urine through bladder catheter, ganglia in the inguinal region, edema in the lower limbs with formation of flictenas on the dorsal zone of the feet. Imaging studies confirmed the presence of mass in a pulmonary region together with pathological fractures at the thoracic level, thus, palliative care was provided, and the patient was discharged from the hospital. Conclusions: Penile cancer is a low prevalence worldwide pathology. Approximately 95% of these cancers are squamous cell carcinomas, which can easily spread locally through lymphatic or vascular channels; nonetheless, its metastatic disease development is rare and mainly affects organs such as the liver, bone, and brain. However, few cases of metastasis to the dorsal spine, heart, retroperitoneum, breast tissue, lung, and skin have been reported.  Introducción: El carcinoma de pene es un tumor infrecuente en nuestro medio con menos del 1% de muertes en el hombre. Se define como el proceso proliferativo y desordenado de las células epiteliales escamosas del pene. Objetivo: Presentar el caso de un paciente que presentó cáncer de pene con metástasis a pulmón. Caso clínico: Paciente de 85 años ingreso por cuadro clínico de 24 horas de evolución consistente en hematuria asociado a tos no productiva, lumbalgia, astenia y adinamia. Tenían antecedentes de carcinoma escamosos de pene, fumador pesado hasta hace dos años, exposición crónica a humo de leña. Al examen físico con regular estado general, ruidos respiratorios sugestivos de hipoventilación izquierda, ausencia de pene por antecedentes y sonda vesical salida de orina hematúrica, ganglios en región inguinal, edema en miembros inferiores con formación de flictenas en cara dorsal de los pies. Los estudios imagenológicos confirmaron la presencia de masa a región pulmonar junto con fracturas patológicas a nivel torácico, por lo que se dio manejo paliativo con egreso hospitalario. Conclusiones: El cáncer de pene es una patología de baja prevalencia a nivel mundial. Aproximadamente el 95% de estos canceres son carcinomas de células escamosas que fácilmente pueden diseminarse localmente a través de canales linfáticos o vasculares, a pesar de ello, la probabilidad de enfermedad metastásica es rara, y afecta principalmente a órganos como el hígado, los huesos y al cerebro, sin embargo, se han reportado pocos casos de metástasis a columna dorsal, corazón, retroperitoneo, tejido mamario masculino, pulmón y metástasis cutáneas. &nbsp

Omecamtiv mecarbil in chronic heart failure with reduced ejection fraction, GALACTIC‐HF: baseline characteristics and comparison with contemporary clinical trials

Aims: The safety and efficacy of the novel selective cardiac myosin activator, omecamtiv mecarbil, in patients with heart failure with reduced ejection fraction (HFrEF) is tested in the Global Approach to Lowering Adverse Cardiac outcomes Through Improving Contractility in Heart Failure (GALACTIC‐HF) trial. Here we describe the baseline characteristics of participants in GALACTIC‐HF and how these compare with other contemporary trials. Methods and Results: Adults with established HFrEF, New York Heart Association functional class (NYHA) ≥ II, EF ≤35%, elevated natriuretic peptides and either current hospitalization for HF or history of hospitalization/ emergency department visit for HF within a year were randomized to either placebo or omecamtiv mecarbil (pharmacokinetic‐guided dosing: 25, 37.5 or 50 mg bid). 8256 patients [male (79%), non‐white (22%), mean age 65 years] were enrolled with a mean EF 27%, ischemic etiology in 54%, NYHA II 53% and III/IV 47%, and median NT‐proBNP 1971 pg/mL. HF therapies at baseline were among the most effectively employed in contemporary HF trials. GALACTIC‐HF randomized patients representative of recent HF registries and trials with substantial numbers of patients also having characteristics understudied in previous trials including more from North America (n = 1386), enrolled as inpatients (n = 2084), systolic blood pressure < 100 mmHg (n = 1127), estimated glomerular filtration rate < 30 mL/min/1.73 m2 (n = 528), and treated with sacubitril‐valsartan at baseline (n = 1594). Conclusions: GALACTIC‐HF enrolled a well‐treated, high‐risk population from both inpatient and outpatient settings, which will provide a definitive evaluation of the efficacy and safety of this novel therapy, as well as informing its potential future implementation

Relação entre problemas disciplinares e desempenho académico e o uso de substâncias psicoativas em crianças colombianas em idade escolar

Introduction: The consumption of psychoactive substances in Colombian youth is considered a public health problem, due to its prevalence and rising characteristics. Studies of the prevalence of drug use in this population indicate the presence of an association with behavioral patterns that lead to an alteration in academic performance and disciplinary problems. Objective: To identify the association between the consumption of psychoactive substances and the presence of academic or disciplinary problems in Colombian adolescents. Materials and methods: This is an analytical cross-sectional study. 80,018 adolescents enrolled in school were included. It was investigated whether the adolescent had academic or disciplinary performance problems, as well as consumption of psychoactive substances during the last 12 months. A description was made of the frequencies of academic or disciplinary problems with the consumption of each of these psychoactive substances. Associations were estimated using binary logistic regression models, and all analyzes were adjusted for the expansion factor. Results: There was a prevalence of 44% for academic problems and 20% for disciplinary problems. Among the substances with the greatest strength of association with disciplinary problems was cocaine (OR 3,18 IC95 2,75-3,69), marihuana (OR 2,93 IC95 2,68-3,20) and inhalants (OR 2,80 IC95 2,40-3,28) and related to academic problems was marijuana (OR 2,39 IC95 2,18-2,61), dick (OR 2,24 IC95 1,88-2,66) e inhalants (OR 2,11 IC95 1,80-2,48). Conclusions: The use of psychoactive substances is related to the presence of academic and disciplinary problems.Introducción: El consumo de sustancias psicoactivas en jóvenes colombianos es considerado un problema de salud pública, debido a su prevalencia ascendente.

ENGIU: Encuentro Nacional de Grupos de Investigación de UNIMINUTO.

El desarrollo del prototipo para el sistema de detección de Mina Antipersona (MAP), inicia desde el semillero ADSSOF perteneciente al programa de Administración en Seguridad y Salud en el trabajo de la UNIMINUTO, se realiza a partir de un detector de metales que emite una señal audible, que el usuario puede interpretar como aviso de presencia de un objeto metálico, en este caso una MAP. La señal audible se interpreta como un dato, como ese dato no es perceptible a 5 metros de distancia, se implementa el transmisor de Frecuencia Modulada FM por la facilidad de modulación y la escogencia de frecuencia de transmisión de acuerdo con las normas y resolución del Ministerio de Comunicaciones; de manera que esta sea la plataforma base para enviar los datos obtenidos a una frecuencia establecida. La idea es que el ser humano no explore zonas peligrosas y buscar la forma de crear un sistema que permita eliminar ese riesgo, por otro lado, buscar la facilidad de uso de elementos ya disponibles en el mercado

Evolution over Time of Ventilatory Management and Outcome of Patients with Neurologic Disease∗

OBJECTIVES: To describe the changes in ventilator management over time in patients with neurologic disease at ICU admission and to estimate factors associated with 28-day hospital mortality. DESIGN: Secondary analysis of three prospective, observational, multicenter studies. SETTING: Cohort studies conducted in 2004, 2010, and 2016. PATIENTS: Adult patients who received mechanical ventilation for more than 12 hours. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Among the 20,929 patients enrolled, we included 4,152 (20%) mechanically ventilated patients due to different neurologic diseases. Hemorrhagic stroke and brain trauma were the most common pathologies associated with the need for mechanical ventilation. Although volume-cycled ventilation remained the preferred ventilation mode, there was a significant (p < 0.001) increment in the use of pressure support ventilation. The proportion of patients receiving a protective lung ventilation strategy was increased over time: 47% in 2004, 63% in 2010, and 65% in 2016 (p < 0.001), as well as the duration of protective ventilation strategies: 406 days per 1,000 mechanical ventilation days in 2004, 523 days per 1,000 mechanical ventilation days in 2010, and 585 days per 1,000 mechanical ventilation days in 2016 (p < 0.001). There were no differences in the length of stay in the ICU, mortality in the ICU, and mortality in hospital from 2004 to 2016. Independent risk factors for 28-day mortality were age greater than 75 years, Simplified Acute Physiology Score II greater than 50, the occurrence of organ dysfunction within first 48 hours after brain injury, and specific neurologic diseases such as hemorrhagic stroke, ischemic stroke, and brain trauma. CONCLUSIONS: More lung-protective ventilatory strategies have been implemented over years in neurologic patients with no effect on pulmonary complications or on survival. We found several prognostic factors on mortality such as advanced age, the severity of the disease, organ dysfunctions, and the etiology of neurologic disease

Cardiac myosin activation with omecamtiv mecarbil in systolic heart failure

BACKGROUND The selective cardiac myosin activator omecamtiv mecarbil has been shown to improve cardiac function in patients with heart failure with a reduced ejection fraction. Its effect on cardiovascular outcomes is unknown. METHODS We randomly assigned 8256 patients (inpatients and outpatients) with symptomatic chronic heart failure and an ejection fraction of 35% or less to receive omecamtiv mecarbil (using pharmacokinetic-guided doses of 25 mg, 37.5 mg, or 50 mg twice daily) or placebo, in addition to standard heart-failure therapy. The primary outcome was a composite of a first heart-failure event (hospitalization or urgent visit for heart failure) or death from cardiovascular causes. RESULTS During a median of 21.8 months, a primary-outcome event occurred in 1523 of 4120 patients (37.0%) in the omecamtiv mecarbil group and in 1607 of 4112 patients (39.1%) in the placebo group (hazard ratio, 0.92; 95% confidence interval [CI], 0.86 to 0.99; P = 0.03). A total of 808 patients (19.6%) and 798 patients (19.4%), respectively, died from cardiovascular causes (hazard ratio, 1.01; 95% CI, 0.92 to 1.11). There was no significant difference between groups in the change from baseline on the Kansas City Cardiomyopathy Questionnaire total symptom score. At week 24, the change from baseline for the median N-terminal pro-B-type natriuretic peptide level was 10% lower in the omecamtiv mecarbil group than in the placebo group; the median cardiac troponin I level was 4 ng per liter higher. The frequency of cardiac ischemic and ventricular arrhythmia events was similar in the two groups. CONCLUSIONS Among patients with heart failure and a reduced ejection, those who received omecamtiv mecarbil had a lower incidence of a composite of a heart-failure event or death from cardiovascular causes than those who received placebo.

Candida bloodstream infections in intensive care units: analysis of the extended prevalence of infection in intensive care unit study

Item does not contain fulltextOBJECTIVES: To provide a global, up-to-date picture of the prevalence, treatment, and outcomes of Candida bloodstream infections in intensive care unit patients and compare Candida with bacterial bloodstream infection. DESIGN: A retrospective analysis of the Extended Prevalence of Infection in the ICU Study (EPIC II). Demographic, physiological, infection-related and therapeutic data were collected. Patients were grouped as having Candida, Gram-positive, Gram-negative, and combined Candida/bacterial bloodstream infection. Outcome data were assessed at intensive care unit and hospital discharge. SETTING: EPIC II included 1265 intensive care units in 76 countries. PATIENTS: Patients in participating intensive care units on study day. INTERVENTIONS: None. MEASUREMENT AND MAIN RESULTS: Of the 14,414 patients in EPIC II, 99 patients had Candida bloodstream infections for a prevalence of 6.9 per 1000 patients. Sixty-one patients had candidemia alone and 38 patients had combined bloodstream infections. Candida albicans (n = 70) was the predominant species. Primary therapy included monotherapy with fluconazole (n = 39), caspofungin (n = 16), and a polyene-based product (n = 12). Combination therapy was infrequently used (n = 10). Compared with patients with Gram-positive (n = 420) and Gram-negative (n = 264) bloodstream infections, patients with candidemia were more likely to have solid tumors (p < .05) and appeared to have been in an intensive care unit longer (14 days [range, 5-25 days], 8 days [range, 3-20 days], and 10 days [range, 2-23 days], respectively), but this difference was not statistically significant. Severity of illness and organ dysfunction scores were similar between groups. Patients with Candida bloodstream infections, compared with patients with Gram-positive and Gram-negative bloodstream infections, had the greatest crude intensive care unit mortality rates (42.6%, 25.3%, and 29.1%, respectively) and longer intensive care unit lengths of stay (median [interquartile range]) (33 days [18-44], 20 days [9-43], and 21 days [8-46], respectively); however, these differences were not statistically significant. CONCLUSION: Candidemia remains a significant problem in intensive care units patients. In the EPIC II population, Candida albicans was the most common organism and fluconazole remained the predominant antifungal agent used. Candida bloodstream infections are associated with high intensive care unit and hospital mortality rates and resource use
