Institutions and journals both have important duties relating to research and publication misconduct. Institutions are responsible for the conduct of their researchers and for encouraging a healthy research environment. Journals are responsible for the conduct of their editors, for safeguarding the research record, and for ensuring the reliability of everything they publish. ⋯ To achieve this, we make the following recommendations. The institutions should:have a research integrity officer (or office) and publish their contact details prominentlyinform journals about cases of proven misconduct that affect the reliability or attribution of the research that they have publishedrespond to journals if they request information about issues, such as, disputed authorship, misleading reporting, competing interests, or other factors, including honest errors, that could affect the reliability of the published studyinitiate inquiries into allegations of research misconduct or unacceptable publication practice raised by journalshave policies supporting a responsible research conduct and systems in place for investigating suspected research misconduct. The journals should:publish the contact details of their editor-in-chief who should act as the point of contact for questions relating to research and publication integrityinform institutions if they suspect misconduct by their researchers, and provide evidence to support these concernscooperate with investigations and respond to institutions' questions about misconduct allegationsbe prepared to issue retractions or corrections (according to the COPE guidelines on retractions) when provided with findings of misconduct arising from investigationshave policies for responding to institutions and other organizations that investigate cases of research misconduct.

Percutaneous central venous cannulation (CVC) in infants and children is a challenging procedure, and it is usually achieved with a blinded, external landmark-guided technique. Recent guidelines from the National Institute for Clinical Excellence (NICE) recommend the use of ultrasound guidance for central venous catheterization in children. The purpose of this study was to evaluate this method in a pediatric and neonatal intensive care unit, assessing the number of attempts, access time (skin to vein), incidence of complication, and the ease of use for central venous access in the neonatal age group. ⋯ In a sample of critically ill patients from a pediatric and neonatal intensive care unit, ultrasound-guided CVC compared with published reports on traditional technique required fewer attempts and less time. It improved the overall success rate, minimized the occurrence of complications during vein cannulation and was easy to apply in neonatal and pediatric patients.

The aim of our study was to compare the effects of suprascapular nerve block in patients with frozen shoulder and diabetes mellitus unresponsive to intraarticular steroid injections. ⋯ Effective results after suprascapular nerve blockage was obtained for the treatment of refractory frozen shoulder cases.

This prospective double-blind randomized study aims to study the hemodynamic changes following fluid preloading with Hydroxyethyl starch (HES) 6% (130/0.4) compared with normal saline (NS) in cardiac surgery patients. ⋯ Fluid preloading with HES led to a significant increase in filling pressure of the left ventricle (PAOP) and cardiac index compared with NS. We believe that HES (130/0.4) could be a suitable solution for fluid preloading in CABG surgery patients. However, further studies are needed on different fluid preloading modalities with different dosing regimens.

Tranexamic acid has been used to reduce bleeding and the subsequent need for blood transfusion in many surgeries. Because orthognathic surgery can be associated with significant bleeding, this study evaluated the efficacy of prophylactic intravenous (IV) tranexamic acid on blood loss during bimaxillary osteotomy. ⋯ Preoperative IV administration of tranexamic acid reduces the amount of blood loss during bimaxillary osteotomy.
