Global overview of the management of acute cholecystitis during the COVID-19 pandemic (CHOLECOVID study)

Background: This study provides a global overview of the management of patients with acute cholecystitis during the initial phase of the COVID-19 pandemic. Methods: CHOLECOVID is an international, multicentre, observational comparative study of patients admitted to hospital with acute cholecystitis during the COVID-19 pandemic. Data on management were collected for a 2-month study interval coincident with the WHO declaration of the SARS-CoV-2 pandemic and compared with an equivalent pre-pandemic time interval. Mediation analysis examined the influence of SARS-COV-2 infection on 30-day mortality. Results: This study collected data on 9783 patients with acute cholecystitis admitted to 247 hospitals across the world. The pandemic was associated with reduced availability of surgical workforce and operating facilities globally, a significant shift to worse severity of disease, and increased use of conservative management. There was a reduction (both absolute and proportionate) in the number of patients undergoing cholecystectomy from 3095 patients (56.2 per cent) pre-pandemic to 1998 patients (46.2 per cent) during the pandemic but there was no difference in 30-day all-cause mortality after cholecystectomy comparing the pre-pandemic interval with the pandemic (13 patients (0.4 per cent) pre-pandemic to 13 patients (0.6 per cent) pandemic; P = 0.355). In mediation analysis, an admission with acute cholecystitis during the pandemic was associated with a non-significant increased risk of death (OR 1.29, 95 per cent c.i. 0.93 to 1.79, P = 0.121). Conclusion: CHOLECOVID provides a unique overview of the treatment of patients with cholecystitis across the globe during the first months of the SARS-CoV-2 pandemic. The study highlights the need for system resilience in retention of elective surgical activity. Cholecystectomy was associated with a low risk of mortality and deferral of treatment results in an increase in avoidable morbidity that represents the non-COVID cost of this pandemic

hTERT Protein Expression in Cytoplasm and Nucleus and its Association With HPV Infection in Patients With Cervical Cancer

BACKGROUND: Few studies have analyzed the association between human telomerase reverse transcriptase (hTERT) protein expression (nuclear and cytoplasmic localization), hTERT methylation status, and human papillomavirus (HPV) genotype infection in cervical cancer. PATIENTS AND METHODS: One hundred seventy-three patients with cervical cancer were analyzed. hTERT protein expression was detected by immunohistochemistry. hTERT DNA methylation analysis was performed using a PCR-RLB-hTERT assay, targeting two regions of the hTERT promoter. Type specific HPV infection was detected by using GP5+/GP6+PCR-RLB. RESULTS: hTERT protein expression was found in both cytoplasm and nucleus (78.0% of the samples showed a cytoplasmic localization and 79.8% had a nuclear localization). A statistically significant association was found between alpha 9 and 7 HPV species with a non-methylation pattern of the hTERT promoter and between these species and high expression of hTERT protein with nuclear localization. CONCLUSION: hTERT protein is found in both the nucleus and cytoplasm of patients with cervical cancer and confirm the relationship between the non-methylated status of hTERT promoter and some HPV species as well as the relationship between these species and hTERT protein expression

Long-term outcomes of Guillain-Barré syndrome possibly associated with Zika virus infection.

BackgroundThis prospective cohort investigation analyzed the long-term functional and neurologic outcomes of patients with Zika virus-associated Guillain-Barré syndrome (GBS) in Barranquilla, Colombia.MethodsThirty-four Zika virus-associated GBS cases were assessed a median of 17 months following acute GBS illness. We assessed demographics, results of Overall Disability Sum Scores (ODSS), Hughes Disability Score (HDS), Zung Depression Scale (ZDS), and Health Related Quality of Life (HRQL) questionnaires; and compared outcomes indices with a normative sample of neighborhood-selected control subjects in Barranquilla without GBS.ResultsMedian age at time of acute neurologic onset was 49 years (range, 10-80); 17 (50%) were male. No deaths occurred. At long-term follow-up, 25 (73%) patients had a HDS 0-1, indicating complete / near complete recovery. Among the group, HDS (mean 1.4, range 0-4), ODSS (mean 1.9, range 0-9) and ZDS score (mean 34.4, range 20-56) indicated mild / moderate ongoing disability. Adjusting for age and sex, Zika virus-associated GBS cases were similar to a population comparison group (n = 368) in Barranquilla without GBS in terms of prevalence of physical or mental health complaints, though GBS patients were more likely to have an ODSS of ≥ 1 (OR 8.8, 95% CI 3.2-24.5) and to suffer from moderate / moderate-severe depression (OR 3.89, 95% CI 1.23-11.17) than the comparison group.ConclusionsLong-term outcomes of Zika virus-associated GBS are consistent with those associated with other antecedent antigenic stimuli in terms of mortality and ongoing long-term morbidity, as published in the literature. Persons with Zika virus-associated GBS more frequently reported disability and depression after approximately one year compared with those without GBS

Biodiversidad 2015. Reporte de Estado y Tendencias de la Biodiversidad Continental de Colombia

El propósito de este documento es fortalecer la capacidad de agentes públicos y privados para la aplicación de la PNGIBSE, que constituye en sí misma una apuesta de interfaz entre ciencia, política y sociedad en la perspectiva de construir sostenibilidad en el desarrollo. Además de ello, representa un insumo para el seguimiento a los compromisos del país frente a convenios e iniciativas internacionales (CDB, IPBES, OCDE), así como un mecanismo pedagógico para generar interés, conciencia y apropiación de las diferentes dimensiones de la biodiversidad del país. En esta oportunidad, el reporte avanza en el desarrollo de nuevas infografías vinculadas con diferentes fuentes de información que garantizan la calidad de los datos con los que se propone y representa el estado de la biodiversidad y de su gestión en Colombia. Incluye como novedad la presentación de material en portal web dedicado (reporte.humboldt.org.co), de manera que todas las personas puedan apropiarse e interactuar con el contenido de manera más efectiva. La perspectiva es construir un modelo en tiempo real del trabajo que se desarrolla en el país para conocer, proteger, utilizar o restaurar su biodiversidad y servicios ecosistémicos, promoviendo la apropiación de todos los ciudadanos e instituciones en la tarea. Biodiversidad 2015, es evidente, aún no está en capacidad de dar cuenta de todos los procesos de gestión de biodiversidad que se dan en Colombia, liderados por múltiples actores y a todas las escalas. Paulatinamente esperamos poder abrir el espacio para incrementar la visibilidad de todas y cada una de las iniciativas que se adelanten, a sabiendas de que la posibilidad de encontrar nuevas respuestas y mejores prácticas no depende del Instituto ni de ninguna instancia en particular, sino de la capacidad colectiva de aprendizaje. Así, esperamos que este nuevo paso en la construcción de un producto colaborativo sea del interés de todos y nos permita avanzar en esa dirección. reporte.humboldt.org.coBogotá, D. C
