Factors associated with trachoma in persistently endemic setting in Southern Ethiopia: a community-based cross-sectional study.

Introduction: in Ethiopia, despite implementing decades-long surgery, antibiotics, facial cleanliness, and environmental improvement interventions, commonly known as the SAFE strategies, persistence and recrudescence of trachoma are common. There is limited evidence that explained the reasons. This study assesses factors associated with trachoma in persistently endemic settings.

Genome-wide transcriptional response to silver stress in extremely halophilic archaeon Haloferax alexandrinus DSM 27206.

Background: The extremely halophilic archaeon Haloferax (Hfx.) alexandrinus DSM 27206 was previously documented for the ability to biosynthesize silver nanoparticles while mechanisms underlying its silver tolerance were overlooked. In the current study, we aimed to assess the transcriptional response of this haloarchaeon to varying concentrations of silver, seeking a comprehensive understanding of the molecular determinants underpinning its heavy metal tolerance.

Comprehensive mineralogical and physicochemical characterization of recent sapropels from Romanian saline lakes for potential use in pelotherapy.

In this study we aimed to compare the mineralogical, thermal, physicochemical, and biological characteristics of recent organic carbon-rich sediments ('sapropels') from three geographically distant Romanian lakes (Tekirghiol and Amara, SE Romania, and Ursu, Central Romania) with distinct hydrogeochemical origins, presently used for pelotherapy. The investigated lakes were classified as inland brackish Na-Cl-sulfated type (Amara), coastal moderately saline and inland hypersaline Na-Cl types (Tekirghiol and Ursu, respectively). The settled organic matter is largely composed of photosynthetic pigments derived from autochthonous phytoplankton.

Needling and open filtering bleb revision after XEN-45 implantation-a retrospective outcome comparison.

Purpose: To compare efficacy and safety of needling and open bleb revision after XEN-45 surgery.

Methods: This retrospective study represents real-life data of patients who underwent XEN-45 surgery between November 2014 and June 2018 in the Vienna General Hospital. The following groups were formed for data evaluation: (PSEA) primary surgery secondary intervention allowed (n = 268); (PS) primary surgery until secondary intervention (n = 268); (N) first needling until additional secondary intervention (n = 55); (BR) first bleb revision until additional secondary intervention (n = 105).
