    Mortality and pulmonary complications in patients undergoing surgery with perioperative SARS-CoV-2 infection: an international cohort study

    Background: The impact of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) on postoperative recovery needs to be understood to inform clinical decision making during and after the COVID-19 pandemic. This study reports 30-day mortality and pulmonary complication rates in patients with perioperative SARS-CoV-2 infection. Methods: This international, multicentre, cohort study at 235 hospitals in 24 countries included all patients undergoing surgery who had SARS-CoV-2 infection confirmed within 7 days before or 30 days after surgery. The primary outcome measure was 30-day postoperative mortality and was assessed in all enrolled patients. The main secondary outcome measure was pulmonary complications, defined as pneumonia, acute respiratory distress syndrome, or unexpected postoperative ventilation. Findings: This analysis includes 1128 patients who had surgery between Jan 1 and March 31, 2020, of whom 835 (74·0%) had emergency surgery and 280 (24·8%) had elective surgery. SARS-CoV-2 infection was confirmed preoperatively in 294 (26·1%) patients. 30-day mortality was 23·8% (268 of 1128). Pulmonary complications occurred in 577 (51·2%) of 1128 patients; 30-day mortality in these patients was 38·0% (219 of 577), accounting for 81·7% (219 of 268) of all deaths. In adjusted analyses, 30-day mortality was associated with male sex (odds ratio 1·75 [95% CI 1·28–2·40], p\textless0·0001), age 70 years or older versus younger than 70 years (2·30 [1·65–3·22], p\textless0·0001), American Society of Anesthesiologists grades 3–5 versus grades 1–2 (2·35 [1·57–3·53], p\textless0·0001), malignant versus benign or obstetric diagnosis (1·55 [1·01–2·39], p=0·046), emergency versus elective surgery (1·67 [1·06–2·63], p=0·026), and major versus minor surgery (1·52 [1·01–2·31], p=0·047). Interpretation: Postoperative pulmonary complications occur in half of patients with perioperative SARS-CoV-2 infection and are associated with high mortality. Thresholds for surgery during the COVID-19 pandemic should be higher than during normal practice, particularly in men aged 70 years and older. Consideration should be given for postponing non-urgent procedures and promoting non-operative treatment to delay or avoid the need for surgery.

    In this paper colored traps were evaluated to capture thrips in mango cv. Ataulfo trees in Soconusco, Chiapas, Mexico. Sticky traps were compared in different colors, blue, yellow and violet. It was placed a trap of each color per tree and they were evaluated in five trees. The results showed that significantly more thrips were caught in violet traps.En este trabajo se evaluaron trampas de colores para capturar trips en árboles de mango cv. Ataulfo en el Soconusco, Chiapas, México. Se compararon trampas pegajosas de color azul, amarillo y violeta. Se colocó una trampa de cada color por árbol y se evaluaron en 5 árboles. Los resultados mostraron que se capturaron significativamente más trips en las trampas de color violeta

    A new species of Pseudophanerotoma (Hymenoptera, Braconidae) from Nayarit, Mexico

    Parasitoid wasps are known to be among the most abundant and species-rich on Earth and thus considered an ecologically important group of arthropods. Braconid wasps play a key role in regulating the populations of Lepidoptera, Coleoptera, and Diptera. However, the biology and taxonomy of numerous parasitoid species remain poorly known. In Mexico, only 17 species of the subfamily Cheloninae have been described. A new species of Pseudophanerotoma Zettel, 1990 (Hymenoptera, Braconidae), P. huichol sp. nov., is described from Nayarit, Mexico. The tortricid moth Cryptaspasma perseana Gilligan & Brown, 2011 is reported as the host of this parasitoid wasp. Detailed taxonomic and barcoding information are provided

    The composition and seasonal occurrence of sandflies were investigated in coffee agroecosystems in the Soconusco region of Chiapas, Mexico. Insect sampling was performed on three plantations located at different altitudes: Finca Guadalupe Zajú [1,000 m above sea level (a.s.l.)], Finca Argovia (613 m a.s.l.) and Teotihuacán del Valle (429 m a.s.l.). Sandflies were sampled monthly from August 2007-July 2008 using three sampling methods: Shannon traps, CDC miniature light traps and Disney traps. Sampling was conducted for 3 h during three consecutive nights, beginning at sunset. A total of 4,387 sandflies were collected during the course of the study: 2,718 individuals in Finca Guadalupe Zajú, 605 in Finca Argovia and 1,064 in Teotihuacán del Valle. The Shannon traps captured 94.3% of the total sandflies, while the CDC light traps and Disney traps captured 4.9% and 0.8%, respectively. More females than males were collected at all sites. While the number of sandflies captured was positively correlated with temperature and relative humidity, a negative correlation was observed between sandfly numbers and rainfall. Five species of sandflies were captured: Lutzomyia cruciata , Lutzomyia texana , Lutzomyia ovallesi , Lutzomyia cratifer / undulata and Brumptomyia sp. Lu. cruciata , constituting 98.8% of the total, was the most abundant species. None of the captured sandflies was infected with Leishmaniaspp

    Se realizó un estudio descriptivo y transversal de 21 puérperas cesareadas, con infección del sitio quirúrgico, ingresadas en el Hospital Ginecoobstétrico Dra. "Nelia Irma Delfín Ripoll" de Palma Soriano, provincia de Santiago de Cuba, desde octubre de 2014 hasta igual mes de 2015, a fin de caracterizarles según variables seleccionadas. En la serie predominaron el grupo etario de 20-29 años, la anemia (66,6 %) y la obesidad (42,8 %) como principales factores de riesgo, la cirugía urgente limpia contaminada (76,1 %), así como el Staphylococcus aureus y la Escherichia coli como los gérmenes más aislados; asimismo, se utilizaron combinaciones de antibióticos de primera línea con resultados favorables en todas las pacientes. Se concluye que la presencia de factores de riesgo y la identificación de bacterias como agentes causales importantes, exige mantener una vigilancia epidemiológica permanente para disminuir la infección en estas paciente
