Reducing the environmental impact of surgery on a global scale: systematic review and co-prioritization with healthcare workers in 132 countries

Background Healthcare cannot achieve net-zero carbon without addressing operating theatres. The aim of this study was to prioritize feasible interventions to reduce the environmental impact of operating theatres. Methods This study adopted a four-phase Delphi consensus co-prioritization methodology. In phase 1, a systematic review of published interventions and global consultation of perioperative healthcare professionals were used to longlist interventions. In phase 2, iterative thematic analysis consolidated comparable interventions into a shortlist. In phase 3, the shortlist was co-prioritized based on patient and clinician views on acceptability, feasibility, and safety. In phase 4, ranked lists of interventions were presented by their relevance to high-income countries and low–middle-income countries. Results In phase 1, 43 interventions were identified, which had low uptake in practice according to 3042 professionals globally. In phase 2, a shortlist of 15 intervention domains was generated. In phase 3, interventions were deemed acceptable for more than 90 per cent of patients except for reducing general anaesthesia (84 per cent) and re-sterilization of ‘single-use’ consumables (86 per cent). In phase 4, the top three shortlisted interventions for high-income countries were: introducing recycling; reducing use of anaesthetic gases; and appropriate clinical waste processing. In phase 4, the top three shortlisted interventions for low–middle-income countries were: introducing reusable surgical devices; reducing use of consumables; and reducing the use of general anaesthesia. Conclusion This is a step toward environmentally sustainable operating environments with actionable interventions applicable to both high– and low–middle–income countries

Small scale structured BaTiO3-based coatings for catalytic coatings

Integration of precious metal in perovskite structures (BaTi0.95M0.05O3, M = Pd, Rh, etc) results in more ageing resistance and higher N2-selectivie catalysts compared to the precious metals supported on single oxides under temperatures exceeding 800°-900°C [1]. Homogeneous dispersed ion metals (i.e. Pt, Pd, Rh) in perovskite structures can result in more active and selective active sites as well. Here a Ba-based perovskite is prepared starting from different synthesis routes and doped with Pd and Rh. The catalytic properties of Rh and Pd-integrated perovskite are studied

Doped TiO2-Nanotubular Sensor Electrodes for Gas Sensing Applications

Relying on its unique properties, titanium dioxide is employed in a versatility of applications, gas sensing being one of them. Low temperature synthesis of doped TiO2-coatings and their nano-structuring enhance these properties. It is reported that the use of one-dimensional (1-D) nanostructures instead of nano-crystalline films yields more than 2-fold increase in efficiency by improving the sensing properties. Nano-tubular sensing electrodes improve sensing performance due to high surface to volume ratio and thus enabling strong interaction between the surrounding gas and the sensing material. This work reports the synthesis of coatings having TiO2-nanotubes by AAO-templated and non-templated anodic oxidation method. Using these coatings gas sensor devices was fabricated and their sensing properties were analyzed towards reducing and oxidizing gases. Long-term stability of the nano-structures was investigated to determine the life-time of sensors. Additionally trivalent additive doped TiO2 nanotubes were synthesized by AAO-templated sol-gel method and phase sequences with composition and temperature were analysed. Sensor properties obtained with various compositions and synthesis methods were compared

Different alternatives of reconstruction for complicated tissue defects localized on proximal femur [Uyluk proksimaline yerleşen komplike doku defektleri için farkli rekonstrüksiyon seçenekleri]

Repair of complex inguinal region defects still creates problems for plastic surgeons. Healing of groin wounds sometimes poses difficulties because of insufficient thickness and poor vascularity of the skin (1). After primary recontrouction, wound infection and dehisence frequently occur (2). For the reconstruction of inguinal region it appears to be necessary to use pediculated or free flaps that are better vascularized, when all these situations have been considered (3). In these reports we discussed different reconstructive alternatives of the inguinal region tissue defects

Incidence of chronic pain after ingunial hernia repair [Inguinal herni onarimi sonrasi kronik agri insidansi]

PubMed ID: 25944136Objectives: The percentage of chronic pain in adults having inguinal hernia repair is 5-35%. Although this pain is thought to be related to some reasons, there is not an exact conclusion about this. In this study, the aim was to point out the incidence of chronic pain after inguinal hernia repair and determination of the risk factors. Methods: Tw o hundred and four patients having inguinal hernia surgery between January 2011 and December 2012 were included into this study. The patients' pain was measured with VA S within 24 hours and at the third and the sixth month after surgery. The patients whose VA S was>3 three months after surgery were evaluated to have chronic pain. Results: The incidence of pain continuing 3 months after surgery was 18.6% and 11.2% six months after surgery. 78.3% of the patients had already had pain before surgery, and in 28% of them, chronic pain had evolved. The measure of VAS within 24 hours postoperatively was found higher in patients who developed chronic pain (3.13±1.12/1.71±1.27). 5.2% of the patients had re-operation for reparation and chronic pain developed in all. Chronic pain was neuropathic in 48% of the patients, and its severity was moderate. Conclusion: The incidence of chronic pain after inguinal hernia repair was found %18, compatible with similar studies. Compared with other risk factors, preoperative pain, postoperative severe acute pain and reoperations were thought to be the most important risk factors for the development of chronic pain
