Lung Cancer Survival in Sri Lanka.

Nuradh Joseph  Lung cancer is the second commonest cancer among males in Sri Lanka. Real-world survival data are scarce, and we conducted a retrospective survival analysis among patients treated for lung cancer.  All patients with primary lung cancer treated at three selected units during 2015-2016 were included in the study.

Systematic review and meta-analysis of cold snare polypectomy and hot snare polypectomy for colorectal polyps.

Background And Aim: Cold snare polypectomy (CSP) has become increasingly utilized to resect colorectal polyps, given its efficacy and safety. This study aims to compare CSP and hot snare polypectomy (HSP) for resecting small (< 10 mm) and large (10-20 mm) colorectal lesions.

Methods: Relevant publications were obtained from Cochrane Library, Embase, Google Scholar, PubMed, and Web of Science databases.

Safety and efficacy of over-the-scope clips versus standard therapy for high-risk nonvariceal upper GI bleeding: systematic review and meta-analysis.

Background And Aims: Upper GI bleeding (UGIB) is a common condition associated with significant morbidity and mortality. Endoscopic hemostasis remains the mainstay of therapy and is mainly aimed at effective hemostasis and prevention of rebleeding. Lesions with high-risk stigmata can have rebleeding rates of as high as 26.

Multi-Axis Force/Torque Sensor Based on Simply-Supported Beam and Optoelectronics.

This paper presents a multi-axis force/torque sensor based on simply-supported beam and optoelectronic technology. The sensor's main advantages are: (1) Low power consumption; (2) low-level noise in comparison with conventional methods of force sensing (e.g.

Embedded electro-conductive yarn for shape sensing of soft robotic manipulators.

Flexible soft and stiffness-controllable surgical manipulators enhance the manoeuvrability of surgical tools during Minimally Invasive Surgery (MIS), as opposed to conventional rigid laparoscopic instruments. These flexible and soft robotic systems allow bending around organs, navigating through complex anatomical pathways inside the human body and interacting inherently safe with its soft environment. Shape sensing in such systems is a challenge and one essential requirement for precise position feedback control of soft robots.

Study on the human perception of incipient and overall slippages using a 2D FE fingertip model.

Slippage on the fingertips is an important phenomenon that occurs constantly in our daily life. However, the mechanism behind the slippage, especially incipient slippage, which appears prior to overall slippage, has not been fully understood. In this paper, a 2D finite element (FE) model of the human fingertip was presented to study how the human fingertip perceives slippages.

Disposable soft 3 axis force sensor for biomedical applications.

This paper proposes a new disposable soft 3D force sensor that can be used to calculate either force or displacement and vibrations. It uses three Hall Effect sensors orthogonally placed around a cylindrical beam made of silicon rubber. A niobium permanent magnet is inside the silicon.
