Restrictive versus goal-directed fluid replacement strategy in ovarian cancer cytoreductive surgery (RiGoROCS): A randomised controlled trial.

Background: Although goal-directed fluid therapy (GDFT) is associated with reduced morbidity and length of stay (LOS) in the hospital after major surgery, it has not been widely studied in ovarian cancer cytoreductive surgery (CRS). The primary objective of the study was post-operative LOS.

Methods: In this double-blind, randomised controlled trial, ovarian cancer patients undergoing elective CRS were randomised to receive either GDFT or restrictive fluid therapy after pre-randomisation stratification for primary debulking surgery or interval debulking surgery.

Comparative performance analysis of 2D and 3D gamma metrics for patient specific QA in VMAT using Octavius 4D with 2D-Array 1500.

Introduction: Gamma pass percentage (GPP) is the predominant metric used for Patient Specific Quality Assurance (PSQA) in radiation therapy. The dimensionality of the measurement geometry in PSQA has evolved from 2D planar to 3D planar, and presently to state-of-the-art 3D volumetric geometry. We aim to critically examine the performance of the three-dimensional gammas vis-à-vis the older gamma metrics of lower dimensionality to determine their mutual fungibility in PSQA, using clinically approved Volumetric Arc Therapy (VMAT) plans.

COVID-19 pandemic and preparedness of anesthesia team in a stand-alone cancer centre in Eastern India.

India came under the grip of the coronavirus disease-2019 (COVID-19) pandemic and is now seeing rising graph. Cancer patients are specially in the high-risk group because of their immunocompromised status on one hand and progressive disease on the other hand. Hence, cancer care facility needs to prepare a clear strategy to manage their space, staff and supplies so that optimum patient care can be continued in the face of COVID-19 pandemic.

Retrospective study on performance of constancy check device in Linac beam monitoring using Statistical Process Control.

Aim: To examine the application of Statistical Process Control (SPC) and Ishikawa diagrams for retrospective evaluation of machine Quality Assurance (QA) performance in radiotherapy.

Background: SPC is a popular method for supplementing the performance of QA techniques in healthcare. This work investigates the applicability of SPC techniques and Ishikawa charts in machine QA.

Existing practice of perioperative management of colorectal surgeries in a regional cancer institute and compliance with ERAS guidelines.

Background And Aims: Enhanced recovery after surgery (ERAS) protocol in colorectal surgery has been shown to result in reduced rates of postoperative complications and length of stay (LOS) in the hospital. Although there is clear guideline and evidences available, their implementation into daily clinical practice faces some difficulties. We aimed to audit the existing practice of perioperative care in colorectal surgeries and find out the adherence to ERAS protocol.

Observation of the formation of anisotropic silver microstructures by evanescent wave and electron microscopy.

Using a well-known galvanic displacement reaction, ∼25-40 μm long silver ribbons grown after mixing ∼50 nm copper particles with AgNO3 solution were observed as a function of Ag(+) concentration and their growth was characterized in real-time and in situ by evanescent wave (EW) microscopy. At low Ag(+) concentration, chain-like structures consisting of both Ag and Cu were observed. When the sequence of mixing these two reactants was reversed, different Ag microstructures (platelets and dendrites) were formed and were also characterized by EW microscopy.
