Comparative Evaluation of the Push-Out Bond Strength of Glass Ionomer Cement, Mineral Trioxide Aggregate, Biodentine, and Endosequence Root Repair Material in Repair of Furcation Perforations: An Study.

Introduction: An comparative analysis was performed to calculate the push-out bond strength of commercially existing root repairing cements like glass ionomer cement (GIC), biodentine, mineral trioxide aggregate (MTA), and endosequence root repair material (RRM) employed in furcation perforation, with or without blood contamination present.

Materials And Methods: Eighty molars were selected and subjected to furcal perforations. They were categorized based on the cement used for repair (GIC, MTA, biodentine, and endosequence RRM); furthermore, they were sub-divided into two sub-groups, that is, blood contaminated and non-contaminated.

Skin manifestations in patients with COVID-19: a prospective observational study during the first wave of the pandemic in the UK and review of the recent literature.

Background: COVID-19 (SARS-CoV-2) is a viral infection that presents in heterogeneous forms with effects on multiple organ systems including the skin.

Objectives: The objectives of this prospective observational study were to identify cutaneous lesions in confirmed COVID-19-positive patients admitted to a district general hospital in the eastern region of England, to determine the prevalence of these lesions and compare the findings with the current literature.

Materials & Methods: The study was conducted at the Luton and Dunstable University Hospital during the first peak of the pandemic in the United Kingdom to identify skin manifestations in patients infected with COVID-19.

Enhancing collaboration during humanitarian response: an interim report from stakeholders survey.

The effectiveness of humanitarian response efforts has long been hampered by a lack of coordination among responding organizations. The need for increased coordination and collaboration, as well as the need to better understand experiences with coordination, were recognized by participants of a multilateral Working Group convened to examine the challenges of coordination in humanitarian health responses. This preliminary study is an interim report of an ongoing survey designed by the Working Group to describe the experiences of coordination and collaboration in greater detail, including factors that promote or discourage coordination and lessons learned, and to determine whether there is support for a new consortium dedicated to coordination.
