Laparoscopic surgery of adrenal cysts: results of a series of 18 patients
Indexación: Web of Science; Scielo.Introducción: Los quistes suprarrenales tienen una incidencia de 0,064% a 0,18% en autopsias. El objetivo de este trabajo es mostrar nuestra experiencia en 18 pacientes portadores de un quiste adrenal operados por vía laparoscópica. Material y Métodos: La serie está constituida por 18 pacientes, de una serie de 344 adrenalectomías laparoscópicas realizadas entre los años 1993 y 2011. El rango de edad fue de 20 a 61 años, con un promedio de 38 años, 11 mujeres y 7 hombres. Resultados: Trece quistes eran del lado izquierdo y 5 del derecho. El tamaño de la lesión varió entre 4,5 y 12,5 cm, con un promedio de 9,2 cm. En 8 pacientes hubo molestias abdominales vagas y en los restantes 12 pacientes no hubo signos ni síntomas de sospecha clínica. La cirugía realizada fue una decorticación-marsupialización laparoscópica en 11 pacientes, adrenalectomía laparoscópica en bloque en 8 casos y adrenalectomía parcial en 1 caso. El tiempo operatorio promedio fue de 83,1 min (30-180 min), y el tiempo medio de hospitalización fue de 36 h. Complicaciones intraoperatorias ocurrieron en 2 pacientes: 1 lesión de diafragma y 1 lesión de vena renal, reparadas en el mismo acto quirúrgico. Complicaciones postoperatorias ocurrieron en 2 pacientes, ambas Clavien 3a y de manejo conservador. Conclusión: Las lesiones pequeñas y no funcionantes requieren observación. La adrenalectomía laparoscópica parcial o total está indicada en lesiones de gran tamaño, con importante compromiso de la glándula o ante la sospecha de lesión funcionante o malignidad.Introduction: Adrenal cysts have an incidence of 0.064% to 0.18% at autopsy. Aim: To show our experience in 18 patients with an adrenal cyst operated by laparoscopy. Material and Methods: The series consisted of 18 patients operated, in a series of 344 laparoscopic adrenalectomy performed between 1993 and 2011. The age range was 20 to 61 years with an average of 38 years, 11 women and 7 men. Results: Thirteen cysts were left and 5 were right sided. The lesion size varied between 4.5 and 12.5 cm, with an average of 9.2 cm. Eight patients complained of abdominal discomfort and in the remaining 12 patients there were no signs or symptoms of clinical suspicion. The surgery performed was a laparoscopic decortication-marsupialization in 11 patients, laparoscopic adrenalectomy in 8 cases and partial adrenalectomy in 1 case. Mean operative time was 83.1 minutes (30-180 minutes), and mean hospital stay was 36 hours. Intraoperative complications occurred in 2 patients: 1 diaphragm injury and one renal vein injury, repaired in the same surgery. Postoperative complications occurred in 2 patients, both Clavien 3a, treated by conservative management. Conclusion: Small and non-functional lesions require observation. Partial or total laparoscopic adrenalectomy is indicated in large lesions or in functional and suspected malignant lesions.http://ref.scielo.org/bm4t5
Malignant pheochromocytoma treated with minimally invasive surgery
Indexación: Web of Science; Scielo.Introducción: El Feocromocitoma es un tumor de células cromafines productor de catecolaminas. Su variedad maligna es muy poco frecuente. Objetivo: Describir 2 casos de Feocromocitoma maligno tratados con cirugía mínimamente invasiva. Casos clínicos: Presentamos 2 pacientes de sexo femenino, de 31 y 51 años respectivamente. La primera con historia de hipertensión arterial de larga data y uso de múltiples fármacos. La segunda paciente debuta con dolor abdominal. En ambos casos los estudios radiológicos y metabólicos confirmaron el diagnóstico de Feocromocitoma. A la primera paciente se le realizó un procedimiento laparoscópico puro, mientras que a la segunda paciente se le realizó un procedimiento laparoscópico asistido por robot. En ambos casos fue necesario realizar adrenalectomía en bloque con el riñón, por compromiso del hilio renal. No hubo complicaciones severas intra ni post-operatorias, como tampoco conversión a cirugía abierta. La histopatología confirmó el diagnóstico de Feocromocitoma maligno con metástasis ganglionares regionales y márgenes quirúrgicos negativos. Ambas se mantienen en control, sin evidencia de recurrencia. Conclusión: El Feocromocitoma maligno puede ser manejado de forma mínimamente invasiva, con morbilidad y resultados oncológicos comparables a cirugía abierta.Introduction: Pheochromocytoma is a tumor derived from chromaffin cells that produces cathecolamines. Malignant pheochromocytomas are extremely rare. Aim: To describe 2 cases of malignant Pheochromocytoma treated with pure laparoscopic and robot assisted surgery. Clinical cases: Two female patients, 31 and 51 years of age, presented with a history of high blood pressure and abdominal pain. Radiologic and metabolic studies confirmed the diagnosis of Pheochromocytoma in both patients. A pure laparoscopic approach was performed in the first patient while a robotic assisted laparoscopy was done in the second patient. In both cases, adrenalectomy with in bloc nephrectomy was performed due to compromise of the renal sinus. There were no complications or conversion to open surgery. Histopathology confirmed the diagnosis of malignant Pheochromocytoma with metastasis to regional nodes and negative surgical margins. At follow-up, there is no evidence of recurrence. Conclusion: Malignant Pheochromocytoma can be treated with minimally invasive surgery, with morbidity and oncological outcomes similar to open approach.http://ref.scielo.org/ksq86
Predicting Survival after Allogeneic Hematopoietic Cell Transplantation in Myelofibrosis : Performance of the Myelofibrosis Transplant Scoring System (MTSS) and Development of a New Prognostic Model
Accurate prognostic tools are crucial to assess the risk/benefit ratio of allogeneic hematopoietic cell transplantation (allo-HCT) in patients with myelofibrosis (MF). We aimed to evaluate the performance of the Myelofibrosis Transplant Scoring System (MTSS) and identify risk factors for survival in a multicenter series of 197 patients with MF undergoing allo-HCT. After a median follow-up of 3.1 years, 47% of patients had died, and the estimated 5-year survival rate was 51%. Projected 5-year risk of nonrelapse mortality and relapse incidence was 30% and 20%, respectively. Factors independently associated with increased mortality were a hematopoietic cell transplantation-specific comorbidity index (HCT-CI) ≥3 and receiving a graft from an HLA-mismatched unrelated donor or cord blood, whereas post-transplant cyclophosphamide (PT-Cy) was associated with improved survival. Donor type was the only parameter included in the MTSS model with independent prognostic value for survival. According to the MTSS, 3-year survival was 62%, 66%, 37%, and 17% for low-, intermediate-, high-, and very high-risk groups, respectively. By pooling together the low- and intermediate-risk groups, as well as the high- and very high-risk groups, we pinpointed 2 categories: standard risk and high risk (25% of the series). Three-year survival was 62% in standard-risk and 25% in high-risk categories (P <.001). We derived a risk score based on the 3 independent risk factors for survival in our series (donor type, HCT-CI, and PT-Cy). The corresponding 5-year survival for the low-, intermediate-, and high-risk categories was 79%, 55%, and 32%, respectively (P <.001). In conclusion, the MTSS model failed to clearly delineate 4 prognostic groups in our series but may still be useful to identify a subset of patients with poor outcome. We provide a simple prognostic scoring system for risk/benefit considerations before transplantation in patients with MF

Risk profiles and one-year outcomes of patients with newly diagnosed atrial fibrillation in India: Insights from the GARFIELD-AF Registry.
BACKGROUND: The Global Anticoagulant Registry in the FIELD-Atrial Fibrillation (GARFIELD-AF) is an ongoing prospective noninterventional registry, which is providing important information on the baseline characteristics, treatment patterns, and 1-year outcomes in patients with newly diagnosed non-valvular atrial fibrillation (NVAF). This report describes data from Indian patients recruited in this registry. METHODS AND RESULTS: A total of 52,014 patients with newly diagnosed AF were enrolled globally; of these, 1388 patients were recruited from 26 sites within India (2012-2016). In India, the mean age was 65.8 years at diagnosis of NVAF. Hypertension was the most prevalent risk factor for AF, present in 68.5% of patients from India and in 76.3% of patients globally (P < 0.001). Diabetes and coronary artery disease (CAD) were prevalent in 36.2% and 28.1% of patients as compared with global prevalence of 22.2% and 21.6%, respectively (P < 0.001 for both). Antiplatelet therapy was the most common antithrombotic treatment in India. With increasing stroke risk, however, patients were more likely to receive oral anticoagulant therapy [mainly vitamin K antagonist (VKA)], but average international normalized ratio (INR) was lower among Indian patients [median INR value 1.6 (interquartile range {IQR}: 1.3-2.3) versus 2.3 (IQR 1.8-2.8) (P < 0.001)]. Compared with other countries, patients from India had markedly higher rates of all-cause mortality [7.68 per 100 person-years (95% confidence interval 6.32-9.35) vs 4.34 (4.16-4.53), P < 0.0001], while rates of stroke/systemic embolism and major bleeding were lower after 1 year of follow-up. CONCLUSION: Compared to previously published registries from India, the GARFIELD-AF registry describes clinical profiles and outcomes in Indian patients with AF of a different etiology. The registry data show that compared to the rest of the world, Indian AF patients are younger in age and have more diabetes and CAD. Patients with a higher stroke risk are more likely to receive anticoagulation therapy with VKA but are underdosed compared with the global average in the GARFIELD-AF.

Impact of COVID-19 on cardiovascular testing in the United States versus the rest of the world
Objectives: This study sought to quantify and compare the decline in volumes of cardiovascular procedures between the United States and non-US institutions during the early phase of the coronavirus disease-2019 (COVID-19) pandemic.
Background: The COVID-19 pandemic has disrupted the care of many non-COVID-19 illnesses. Reductions in diagnostic cardiovascular testing around the world have led to concerns over the implications of reduced testing for cardiovascular disease (CVD) morbidity and mortality.
Methods: Data were submitted to the INCAPS-COVID (International Atomic Energy Agency Non-Invasive Cardiology Protocols Study of COVID-19), a multinational registry comprising 909 institutions in 108 countries (including 155 facilities in 40 U.S. states), assessing the impact of the COVID-19 pandemic on volumes of diagnostic cardiovascular procedures. Data were obtained for April 2020 and compared with volumes of baseline procedures from March 2019. We compared laboratory characteristics, practices, and procedure volumes between U.S. and non-U.S. facilities and between U.S. geographic regions and identified factors associated with volume reduction in the United States.
Results: Reductions in the volumes of procedures in the United States were similar to those in non-U.S. facilities (68% vs. 63%, respectively; p = 0.237), although U.S. facilities reported greater reductions in invasive coronary angiography (69% vs. 53%, respectively; p < 0.001). Significantly more U.S. facilities reported increased use of telehealth and patient screening measures than non-U.S. facilities, such as temperature checks, symptom screenings, and COVID-19 testing. Reductions in volumes of procedures differed between U.S. regions, with larger declines observed in the Northeast (76%) and Midwest (74%) than in the South (62%) and West (44%). Prevalence of COVID-19, staff redeployments, outpatient centers, and urban centers were associated with greater reductions in volume in U.S. facilities in a multivariable analysis.
Conclusions: We observed marked reductions in U.S. cardiovascular testing in the early phase of the pandemic and significant variability between U.S. regions. The association between reductions of volumes and COVID-19 prevalence in the United States highlighted the need for proactive efforts to maintain access to cardiovascular testing in areas most affected by outbreaks of COVID-19 infection

Global urban environmental change drives adaptation in white clover
Urbanization transforms environments in ways that alter biological evolution. We examined whether urban environmental change drives parallel evolution by sampling 110,019 white clover plants from 6169 populations in 160 cities globally. Plants were assayed for a Mendelian antiherbivore defense that also affects tolerance to abiotic stressors. Urban-rural gradients were associated with the evolution of clines in defense in 47% of cities throughout the world. Variation in the strength of clines was explained by environmental changes in drought stress and vegetation cover that varied among cities. Sequencing 2074 genomes from 26 cities revealed that the evolution of urban-rural clines was best explained by adaptive evolution, but the degree of parallel adaptation varied among cities. Our results demonstrate that urbanization leads to adaptation at a global scale
Search for eccentric black hole coalescences during the third observing run of LIGO and Virgo
Despite the growing number of confident binary black hole coalescences observed through gravitational waves so far, the astrophysical origin of these binaries remains uncertain. Orbital eccentricity is one of the clearest tracers of binary formation channels. Identifying binary eccentricity, however, remains challenging due to the limited availability of gravitational waveforms that include effects of eccentricity. Here, we present observational results for a waveform-independent search sensitive to eccentric black hole coalescences, covering the third observing run (O3) of the LIGO and Virgo detectors. We identified no new high-significance candidates beyond those that were already identified with searches focusing on quasi-circular binaries. We determine the sensitivity of our search to high-mass (total mass M>70 M⊙) binaries covering eccentricities up to 0.3 at 15 Hz orbital frequency, and use this to compare model predictions to search results. Assuming all detections are indeed quasi-circular, for our fiducial population model, we place an upper limit for the merger rate density of high-mass binaries with eccentricities 0<e≤0.3 at 0.33 Gpc−3 yr−1 at 90\% confidence level
Tras las huellas de los asentamientos asturienses. Intervenciones arqueológicas en El Alloru, la Sierra Plana de la Borbolla y otros sitios mesolíticos del oriente de Asturias
A pesar de la gran abundancia de yacimientos atribuibles a este período (unos 130 sólo en el oriente de
Asturias) (Fano 1998), la información disponible para el
estudio de las áreas de hábitat de las sociedades relacionadas con el complejo arqueológico costero conocido como
asturiense (viii-vi milenios cal BC) es muy escasa. Es éste
un problema que ya preocupó al propio conde de la Vega
del Sella, quien abogó por la existencia de espacios habitacionales al aire libre próximos a las cavidades (Vega del Sella 1923), pues éstas no habrían podido ser utilizadas para
esta finalidad, dado que en algunos casos los concheros las
habrían colmatado completamente. Años más tarde, G. A.
Clark trató de contrastar esta hipótesis excavando frente a la boca de la cueva de La Riera (Clark, 1974), donde creyó
haber documentado indicios de ocupaciones asturienses
al aire libre. No obstante, estos resultados fueron cuestionados por revisiones posteriores (González Morales, 1982,
Arias, 1991). Por el contrario, en la base del conchero de
Mazaculos II se encontraron indicios de un asentamiento
en la entrada de la cueva (González Morales, 1982), lo que
volvió a poner sobre la mesa la posibilidad de la existencia
de asentamientos hipogeos en el Mesolítico Cantábrico,
planteamiento que fue considerado en trabajos posteriores,
al evaluar la habitabilidad de las cavidades con conchero
(Arias, 1991). Observaciones efectuadas en los años 1990,
como la relativa a la topografía del terreno inmediato a las
cuevas, no siempre favorable a la existencia de ocupaciones
exteriores, corroboraron esa posibilidad, pero sin negar la
probable presencia de asentamientos al aire libre (Fano,
1998).info:eu-repo/semantics/publishedVersio
