Background The Lancet Commission on Global Surgery (LCoGS) published its seminal report in 2015, carving a niche for global surgery academia. Six years after the LCoGS, a scoping review was conducted to see how the term 'global surgery' is characterized by the literature and how it relates to LCoGS and its domains. Methods PubMed was searched for publications between January 2015 and February 2021 that used the term ‘global surgery’ in the title, abstract, or key words or cited the LCoGS. Variables extracted included LCoGS domains, authorship metrics, geographic scope, and clinical specialty. Results The search captured 938 articles that qualified for data extraction. Nearly 80% of first and last authors had high-income country affiliations. Africa was the most frequently investigated region, though many countries within the region were under-represented. The World Journal of Surgery was the most frequent journal, publishing 13.9% of all articles. General surgery, pediatric surgery, and neurosurgery were the most represented specialties. Of the LCoGS domains, healthcare delivery and management were the most studied, while economics and financing were the least studied. Conclusion A lack of consensus on the definition of global surgery remains. Additional research is needed in economics and financing, while obstetrics and trauma are under-represented in literature using the term ‘global surgery’. Efforts in academic global surgery must give a voice to those carrying the global surgery agenda forward on the frontlines. Focusing on research capacity-building and encouraging contribution by local partners will lead to a stronger, more cohesive global surgery community.

Background The principles of global surgery should be taught as a part of the core curriculum in medical schools. The need for medical students to be familiar with the topic is increasing in acceptance. There is, however, a paucity of data on how medical students are exposed to global surgery. This study aims to evaluate exposure of medical students to global surgery, awareness of the key messages of the Lancet Commission on Global Surgery, global surgery career aspirations and barriers to said aspirations. Methods ISOMERS was a multi-centre, online, cross-sectional survey of final year medical students globally. The questionnaire utilised a combination of Likert-scale, multiple-choice, and free text questions. Results In this study, 1593 final year medical students from 144 medical schools in 20 countries participated. The majority (n = 869/1496, 58.1%) believed global surgery to be relevant, despite 17.7% (n = 271/1535) having any exposure to global surgery. Most participants (n = 1187/1476, 80.4%) wanted additional resources on global surgery. Difficulty in providing appropriate care for patients living abroad (n = 854/1242, 68.8%) was the most common perceived barrier to a career in global surgery. Conclusions Participants believed global surgery was a relevant topic for medical students and wanted additional resources that they could access on global surgery. It is critical for medical students to become aware that global surgery is a field that aims to address inequity in surgical care not just internationally, but nationally and locally as well.

Background Cancellations of elective surgeries on the day of surgery (DOS) can lead to added financial burden and wastage of resources for healthcare facilities; as well as social and emotional problems to patients. These cancellations act as barriers to delivering efficient surgical services. Optimal utilisation of the available resources is necessary for resource-constrained low-and-middle-income countries (LMIC). This study investigates the rate and causes of cancellations of elective surgeries on the DOS in various surgical departments across ten hospitals in India. Methods A research consortium ‘IndSurg’ led by World Health Organisation Collaboration Centre (WHOCC) for Research in Surgical Care Delivery in LMICs, India conducted this multicentre retrospective cross-sectional study to analyse the cancellations of elective/planned surgical operations on DOS across urban secondary and tertiary level hospitals. We audited surgical records of a pre-decided period of six weeks for cancellations, documented relevant demographic information and reasons for cancellations. Results We analysed records from the participating hospitals, with an overall cancellation rate of 9.7% (508/5231) on the DOS for elective surgical operations. Of these, 74% were avoidable cancellations. A majority (30%) of these 508 cancellations were attributed to insufficient resources, 28% due to patient's refusal or failure to show-up, and 22% due to change in patient's medical status. Conclusion We saw a preponderance of avoidable reasons for elective surgery cancellations. A multidisciplinary approach with adequate preoperative patient counselling, timely communication between the patients and caregivers, adequate preoperative anaesthetic assessment, and planning by the surgical team may help reduce the cancellation rate.

DDOS attacks have increased lately to an extent where large companies have lost millions. They pose a large threat to internet security. This paper explains DOS and DDOS attacks and their types as well as two computer softwares -LOIC and DDOSIM -to launch DDOS attacks and the history of the well-known botnets and DDOS attacks. A solution for DDOS protection at application layer is also proposed. It explores the combination of various tools and techniques like ingress filtering, IP address blacklist checker and dividing the server as a measure to limit the attacks. General TermsDDOS protection, dividing and limiting, types of DOS attacks, types of DDOS attacks.
