Revisión del género Mimophytum Greenm. (Boraginaceae)

A morphological description of the genus Mimophytum Greenm. (Boraginaceae) is provided, as well as a dichotomous key to the species and ecological and distributional information. The genus is endemic to the Sierra Madre Oriental of Mexico. Morphological descriptions for the two species are provided. One of them, M. benitomartinezii, is proposed as new to science. It differs from M. omphalodoides in that the stems are rhizomatous-stoloniferous, the upper leaf surfaces are glabrous, the leaf blades possess 3 basal nerves, the inflorescence is an ebracteate, scorpioid cyme, the pedicels are shorter, and the fruits have glochids forming a ring around the edges.Se presenta una descripción morfológica del género Mimophytum Greenm.

Algorithm for the prediction of the reactive forces developed in the socket of transfemoral amputees

Based on a mathematical model of the human gait, a Matlab 2010a algorithm is presented to predict the reaction forces and moments in a particular point along the socket linked to the lower limb of a transfemoral amputee. The model takes the inertia developed due the swing of the limb during the gait into consideration. A validation of the results is made with the data obtained in a gait lab, and the model results are consistent with those obtained in the gait lab

Mortality from gastrointestinal congenital anomalies at 264 hospitals in 74 low-income, middle-income, and high-income countries: a multicentre, international, prospective cohort study

Summary Background Congenital anomalies are the fifth leading cause of mortality in children younger than 5 years globally. Many gastrointestinal congenital anomalies are fatal without timely access to neonatal surgical care, but few studies have been done on these conditions in low-income and middle-income countries (LMICs). We compared outcomes of the seven most common gastrointestinal congenital anomalies in low-income, middle-income, and high-income countries globally, and identified factors associated with mortality. Methods We did a multicentre, international prospective cohort study of patients younger than 16 years, presenting to hospital for the first time with oesophageal atresia, congenital diaphragmatic hernia, intestinal atresia, gastroschisis, exomphalos, anorectal malformation, and Hirschsprung’s disease. Recruitment was of consecutive patients for a minimum of 1 month between October, 2018, and April, 2019. We collected data on patient demographics, clinical status, interventions, and outcomes using the REDCap platform. Patients were followed up for 30 days after primary intervention, or 30 days after admission if they did not receive an intervention. The primary outcome was all-cause, in-hospital mortality for all conditions combined and each condition individually, stratified by country income status. We did a complete case analysis. Findings We included 3849 patients with 3975 study conditions (560 with oesophageal atresia, 448 with congenital diaphragmatic hernia, 681 with intestinal atresia, 453 with gastroschisis, 325 with exomphalos, 991 with anorectal malformation, and 517 with Hirschsprung’s disease) from 264 hospitals (89 in high-income countries, 166 in middleincome countries, and nine in low-income countries) in 74 countries. Of the 3849 patients, 2231 (58·0%) were male. Median gestational age at birth was 38 weeks (IQR 36–39) and median bodyweight at presentation was 2·8 kg (2·3–3·3). Mortality among all patients was 37 (39·8%) of 93 in low-income countries, 583 (20·4%) of 2860 in middle-income countries, and 50 (5·6%) of 896 in high-income countries (p<0·0001 between all country income groups). Gastroschisis had the greatest difference in mortality between country income strata (nine [90·0%] of ten in lowincome countries, 97 [31·9%] of 304 in middle-income countries, and two [1·4%] of 139 in high-income countries; p≤0·0001 between all country income groups). Factors significantly associated with higher mortality for all patients combined included country income status (low-income vs high-income countries, risk ratio 2·78 [95% CI 1·88–4·11], p<0·0001; middle-income vs high-income countries, 2·11 [1·59–2·79], p<0·0001), sepsis at presentation (1·20 [1·04–1·40], p=0·016), higher American Society of Anesthesiologists (ASA) score at primary intervention (ASA 4–5 vs ASA 1–2, 1·82 [1·40–2·35], p<0·0001; ASA 3 vs ASA 1–2, 1·58, [1·30–1·92], p<0·0001]), surgical safety checklist not used (1·39 [1·02–1·90], p=0·035), and ventilation or parenteral nutrition unavailable when needed (ventilation 1·96, [1·41–2·71], p=0·0001; parenteral nutrition 1·35, [1·05–1·74], p=0·018). Administration of parenteral nutrition (0·61, [0·47–0·79], p=0·0002) and use of a peripherally inserted central catheter (0·65 [0·50–0·86], p=0·0024) or percutaneous central line (0·69 [0·48–1·00], p=0·049) were associated with lower mortality. Interpretation Unacceptable differences in mortality exist for gastrointestinal congenital anomalies between lowincome, middle-income, and high-income countries. Improving access to quality neonatal surgical care in LMICs will be vital to achieve Sustainable Development Goal 3.2 of ending preventable deaths in neonates and children younger than 5 years by 2030

El azúcar se tiñó de sangre. Análisis del papel del Estado en la masacre del 18 de octubre de 1977, en el ingenio azucarero Aztra de La Troncal

La masacre de Aztra, nombre con el que se conoce a un suceso represivo por parte de la dictadura militar de Ecuador de los años 70, a la huelga que estalló el 18 de octubre de 1977, en las instalaciones del ingenio Azucarero Aztra de la Troncal, debido a que los obreros solicitaban el cumplimiento del III Contrato Colectivo firmado entre la empresa y los trabajadores. Donde la policía procedió a desalojar por la fuerza a las personas amotinadas dentro de las instalaciones del Ingenio. Lo que dejó como saldo 24 personas muertas y varios desaparecidos. Esta investigación consiste en el análisis crítico de noticias de periódicos, revistas y entrevistas a las personas que estuvieron en la masacre, tratando de entender cuáles fueron las motivaciones que tuvieron los trabajadores, el papel del Estado y las consecuencias que se dieron de este fatal suceso.The massacre of Aztra, name by which a repressive event is known by the military dictatorship of Ecuador in the 70s. This occurred by the strike that broke out on October 18, 1977, at the facilities of Azucarero Aztra sugar mill. Of the Trunk. Because it was requested, the fulfillment of the III Collective Contract signed between the company and the workers. Where the police proceeded to forcibly evict the mutineers inside the facilities of the Ingenio. What left as balance 24 people dead and several disappeared. This investigation consists in the critical analysis of news of newspapers, magazines and interviews to the people who were in the massacre, trying to understand what were the motivations that the workers had, the role of the State and the consequences that occurred of this fatal event.Licenciado en Ciencias de la Educación, Especialización Historia y GeografíaCuenc

Designing Fresnel microlenses for focusing astigmatic multi-Gaussian beams by using fractional order Fourier transforms Designing Fresnel microlenses for focusing astigmatic multi-Gaussian beams by using fractional order Fourier transforms

International audienceAccording to a scalar theory of diffraction, light propagation can be expressed by two-dimensional fractional order Fourier transforms. Since the fractional Fourier transform of a chirp function is a Dirac distribution, focusing a light beam is optically achieved by using a diffractive screen whose transmission function is a two–dimensional chirp function. This property is applied to designing Fresnel microlenses, and the orders of the involved Fourier fractional transforms depend on diffraction distances as well as on emitter and receiver radii of curvature. If the emitter is astigmatic (with two principal radii of curvature), the diffraction phenomenon involves two one-dimensional fractional Fourier transforms whose orders are different. This degree of freedom allows us to design microlenses that can focus astigmatic Gaussian beams, as produced by a line-shaped laser diode source

ANGLE CLOSURE AND MYOPIC SHIFT AFTER TOPIRAMATE USED FOR APPETITE CONTROL: ANTERIOR SEGMENT OPTICAL COHERENCE TOMOGRAPHY FOLLOW-UP WITHOUT CYCLOPLEGIC TREATMENT

A 25 year-old female with a history of topiramate use presented with blurry vision and frontal headache. Acute angle closure was diagnosed and topical hypotensive medication were started without the use of cycloplegics. Anterior segment optical coherence tomography images were taken with analysis of iridocorneal angle at days 1, 3 and 10 documenting every step of angle aperture
