El objetivo fue determinar cuáles son las percepciones de distintos actores del sistema de salud
colombiano sobre los problemas del sistema que están detrás de la crisis. Se realizó un estudio
cualitativo a partir de entrevistas semiestructuradas y en profundidad con cuarenta agentes del
sect...or salud, en Bogotá, Cali, Ibagué, Espinal y Calima-Darién. Los resultados mostraron que la
corrupción, el incumplimiento de normas y los conflictos entre los intereses de diversos actores
del sistema debilitan la legitimidad de este último, atomizan la cooperación y cohesión de los
actores y fortalecen el interés particular.

Francophone Africa still carries a high burden of communicable and neonatal diseases, probably due to the weakness of health-care systems and services, as evidenced by the almost complete attribution of DALYs to YLLs. To cope with this burden of disease, franco...phone Africa should define its priorities and invest more resources in health-system strengthening and in the quality and quantity of health-care services, especially in rural and remote areas. The region could also be prioritised in terms of technical and financial assistance focused on achieving these goals, as much as on demographic investments including education and family planning

Microplastic debris floating at the ocean surface can harm marine life. Understanding the severity of this harm requires knowledge of plastic abundance and distributions. Dozens of expeditions measuring microplastics have been carried out since the 1970s, but they ha...ve primarily focused on the North Atlantic and North Pacific accumulation zones, with much sparser coverage elsewhere. Here, we use the largest dataset of microplastic measurements assembled to date to assess the confidence we can have in global estimates of microplastic abundance and mass. We use a rigorous statistical framework to standardize a global dataset of plastic marine debris measured using surface-trawling plankton nets and coupled this with three different ocean circulation models to spatially interpolate the observations. Our estimates show that the accumulated number of microplastic particles in 2014 ranges from 15 to 51 trillion particles, weighing between 93 and 236 thousand metric tons, which is only approximately 1% of global plastic waste estimated to enter the ocean in the year 2010. These estimates are larger than previous global estimates, but vary widely because the scarcity of data in most of the world ocean, differences in model formulations, and fundamental knowledge gaps in the sources, transformations and fates of microplastics in the ocean.

TB situation in vulnerable populations. Rev. Nac. (Itauguá) vol.13 no.1 Itauguá jun. 2021
La pandemia de covid-19 ha afectado la detección y tratamiento de pacientes con TBC en Paraguay que lejos de ser una enfermedad erradicada, es motivo de preocupación sanitaria y sigue afectando a miles de ...personas, si bien se inician actividades de campo con apoyo del PNCT para la búsqueda activa, seguimiento de casos y control de contactos en comunidades indígenas y asentamientos, estas tareas no son continuas debido al aumento de los casos de covid-19 en el país, que favorece el temor a acudir a los hospitales para el diagnóstico, a sus controles e incluso se ve afectado el retiro de los medicamentos. En el marco de la pandemia, es probable que aumenten los fracasos terapéuticos con el consiguiente desenlace fatal, por lo que debe hacerse una revisión de las estrategias dirigidas a poblaciones vulnerables con un compromiso verdadero del sector político, sumado a una fuerte colaboración multisectorial e intercultural para lograr el fin de la TBC

Phillips and colleagues have shown that rifampicin combined with clarithromycin is non-inferior to RS8, and is safer. This much anticipated trial provides us with a high degree of confidence that an 8-week course of oral rifampicin and clarithromycin should now be the cornerstone of the treatment of... Buruli ulcer everywhere. However, this finding does not mean that
Buruli ulcer is cured at 8 weeks.

Buruli ulcer caused by Mycobacterium ulcerans is a neglected tropical disease characterized by extensive ulceration involving predominantly the upper and lower limbs of patients. The disease is common in rural tropical communities in West and Central Africa, where access to proper health care is lim...ited. Pathogenesis of the characteristic painless ulcers is linked to the elaboration by M. ulcerans of a lipid toxin called mycolactone that has potent cytopathic, immunosuppressive, and analgesic effects on a host of cells in cutaneous tissues. Mycolactone is known to profoundly inhibit secretion of a plethora of proteins that are essential for wound healing. Even though a combination antibacterial therapy of streptomycin and rifampicin for 8 weeks is effective for treatment, it relies on good and appropriate wound management to prevent secondary bacterial infections and improve healing. Evidence-based interventions for wound care in Buruli ulcer disease are often lacking and have relied on expert advice and recommendations. Surgical interventions are limited to debridement of necrotic tissue and grafting of extensive ulcers, usually after antibiotic therapy. Patients’ rehabilitation is an important component of care to reduce disabilities associated with the disease and proper integration into the community after treatment.

Nat Commun 9, 5370 (2018). https://doi.org/10.1038/s41467-018-07804-8. Mycobacterium ulcerans is the causative agent of Buruli ulcer, a neglected tropical skin disease that is most commonly found in children from West and Central Africa. Despite the severity of the infection, therapeutic options are... limited to antibiotics with severe side effects. Here, we show that M. ulcerans is susceptible to the anti-tubercular drug Q203 and related compounds targeting the respiratory cytochrome bc1:aa3. While the cytochrome bc1:aa3 is the primary terminal oxidase in Mycobacterium tuberculosis, the presence of an alternate bd-type terminal oxidase limits the bactericidal and sterilizing potency of Q203 against this bacterium. M. ulcerans strains found in Buruli ulcer patients from Africa and Australia lost all alternate terminal electron acceptors and rely exclusively on the cytochrome bc1:aa3 to respire. As a result, Q203 is bactericidal at low dose against M. ulcerans replicating in vitro and in mice, making the drug a promising candidate for Buruli ulcer treatment.
