Home-based Detection and Prediction of Diabetic Foot Ulcers at Early Stage Using Sensor Technology and Supervised Learning

Journal of Harbin Institute of Technology(New Series) 2024年第1期31卷 26-37页

作者： kamasamudram Bhavya Sai Rishi Raghu Sai Surya Varshith Nukala jayashree Jayaraman Vijayashree Jayaraman School of Computer Science and Engineering Vellore Institute of TechnologyVellore 632014India

For years,foot ulcers linked with diabetes mellitus and neuropathy have significantly impacted diabetic patients’ health-related quality of life(HRQoL). Diabetes foot ulcers impact15% of all diabetic patients at some point in their lives. The facilities and resources used for DFU detection and treatment are only available at hospitals and clinics,which results in the unavailability of feasible and timely detection at an early stage. This necessitates the development of an at-home DFU detection system that enables timely predictions and seamless communication with users,thereby preventing amputations due to neglect and severity. This paper proposes a feasible system consisting of three major modules:an IoT device that works to sense foot nodes to send vibrations onto a foot sole,a machine learning model based on supervised learning which predicts the level of severity of the DFU using four different classification techniques including XGBoost,k-SVM,Random Forest,and Decision tree,and a mobile application that acts as an interface between the sensors and the patient. Based on the severity levels,necessary steps for prevention,treatment,and medications are recommended via the application.

Advancing frontiers in anaesthesiology with laparoscopy

引用

World Journal of Gastroenterology 2014年第39期20卷 14308-14314页

作者： jayashree Sood Department of Anaesthesiology Pain and Perioperative Medicine Sir Ganga Ram Hospital Old Rajinder Nagar New Delhi 110060 India

The introduction of laparoscopy in the surgeon’s armamentarium was in fact a “revolution in the history of surgery”. Since this technique involves insufflation of carbon dioxide it produces several pathophysiological changes which have to be understood by the anaesthesiologist who can modify the anaesthesia technique accordingly. Advantages of laparoscopy include reduced pain, small scars and early return to work. Certain complications specific to laparoscopic surgery are due to carboperitoneum and increased intra-abdominal pressure. Venous air embolism, although very rare, can be lethal if not managed promptly. Other complications include subcutaneous emphysema, haemodynamic compromise and arrhythmias. Although associated with minimal postoperative morbidity, postoperative pain, nausea and vomiting can be quite problematic. The limitations of laparoscopy have been overcome by the introduction of robotic surgery. There are important implications for the anaesthesiologist during robotic surgeries which have to be practiced accordingly. Robotic surgery has a learning curve for both the surgeon and the anaesthesiologist. The robot is bulky, and cannot be disengaged after docking. Therefore it is important that the anaesthetized patient remains immobile throughout surgery and anaesthesia is reversed only after the robot has been disengaged at the end of surgery. Advances in laparoscopy and robotic surgery have modified anaesthetic techniques too.

This study investigates the effects of conserved tills on the fluxes of carbon dioxide(CO_(2))and soil organic carbon(SOC)from a rain-fed-paddy plot in Assam(North-eastern state of India).Two paddy plots identical in soil properties,developed to cultivate rice(Sali,grown in low-lying areas of Assam),were adjacent to each other to follow a conventional agricultural practice in one and conservation in the *** chambers(1 m×0.6 m×0.4 m)were placed in both the plots to collect runoff for analyzing CO_(2) *** results of the both practices have been *** conservation plot,the SOC was high in the range from 3.17+0.01 kg m^(−2) to 20.42+0.56 kg m^(−2) and the CO_(2) emission was less,i.e.97.30+7.11 mg m^(−2) h^(-1) as compared to 189.65+4.37 mg m^(−2) h^(-1) of the conventional *** tillage practiced for the conservation plot facilitated higher porosity(50.11+8.40%to 88.87+3.59%)and greater water retention(47.47+1.15%to 101.37+1.63%)in the *** results indicate that more tillage exposed the soil to atmospheric oxygen more,which leads to excess mineralization of organic carbon and emissions of CO_(2) as in the conventional plot.
