The predominant aim of the current research was to generate a proposal for the removal of arsenic, a highly toxic pollutant, encountered within the Papallacta Lagoon in Ecuador. The average concentrations of As yielded ranges between 18 to 652 μg/L, through the use of metallic nanoparticles. Sampling was performed in the lagoon with their respective geographic locations and "in situ" parameters.

Article Synopsis
  • The Delphi consensus study, conducted by IHPBA-APHPBA, aimed to create global practice guidelines for managing gallbladder cancer (GBC).
  • Experts from 17 countries participated in a four-round consensus process, where 68 clinical questions were posed and a consensus was reached if more than 75% of participants agreed.
  • The study achieved consensus on 92.6% of the questions, covering important aspects of GBC management, but noted that further research is needed on unresolved issues such as the definitions of borderline resectable and locally advanced GBC.

Study Question: Does double stimulation, followed by a fresh embryo transfer (DUOSTIM fresh) give a higher number of good-quality blastocysts as compared with a single stimulation in young low prognosis patients?

Summary Answer: Compared to single stimulation, DUOSTIM fresh leads to a significantly higher number of good quality blastocysts, without hindering fresh embryo transfer outcomes.

What Is Known Already: DUOSTIM (ovarian stimulation both in the follicular and luteal phase of the same cycle) is an innovative strategy to retrieve a higher number of oocytes in a shorter time frame, thus it is particularly appealing for poor ovarian responders. Three current limitations of dual stimulation are: (i) it is unclear whether outcomes of the second (luteal) wave result from the second stimulation, or a carry-over effect from previous follicular stimulation; (ii) the desynchronization between endometrium and ovaries and, (iii) lack of robust evidence.

Choosing Wisely is an initiative by the American Board of Internal Medicine (ABIM) and ABIM Foundation to deter unnecessary medical treatments and procedures. Faced with the burden of modern technologies and treatments, it is crucial to identify practices lacking value in daily care. The Latin American and Caribbean Society (SLACOM), comprising cancer control experts, deems it vital to tailor this initiative for enhancing cancer care in the region.

Background: Antigen detection in Taenia solium cysticercosis confirms viable infection in the intermediate host (either pig or human). The reference B158/B60 monoclonal antibody (mAb)-based Ag-enzyme-linked immunosorbent assay (ELISA) has acceptable levels of sensitivity and specificity in human neurocysticercosis with multiple brain cysts, although its sensitivity is lower in cases with single brain cysts, whereas in porcine cysticercosis the assay specificity is affected by its frequent cross-reaction with Taenia hydatigena, another common cestode found in pigs. Our group has produced 21 anti-T.
