Authors: Wang Qiang , Chen Chengxin , Li Haiyang 
Published: March 2022

BackgroundThe safety and efficacy of laparoscopic pancreaticoduodenectomy (LPD) in elderly patients who often suffer from pre-existing conditions (e.g., cardiovascular diseases) and poor functional reserve remain unclear. This meta-analysis aimed to evaluate the safety and efficacy of LPD in elderly patients.MethodsA systematic literature search was conducted using the PubMed, Embase, Web of Science, and Cochrane Library databases. All studies published from their inception to January 2022 reporting perioperative outcomes after LPD in elderly patients were included in the search (Group 1, comparing the perioperative outcomes of LPD and OPD in elderly patients; Group 2, comparing the perioperative outcomes after LPD between elderly and non-elderly patients). The evaluated outcomes included perioperative mortality, postoperative complications, conversion, operative time, estimated blood loss (EBL), postoperative hospital stay (POHS), and readmission.ResultsIn total 8 studies were included in the meta-analysis. Pooled analysis of Group 1 showed that EBL, 90-day mortality, major morbidity, bile leak, POH, abdominal infection, reoperation, POP, POCE, and readmission were not significantly different between the LPD and the OPD group. LPD was associated with longer operative time, lower POPF rate, lower DEG rate, and shorter POHS. Pooled analysis of Group 2 showed that mortality, major morbidity, POPF, DEG, bile leak, POH, abdominal infection, reoperation, conversion, operative time, EBL, and readmission were not significantly different between the elderly and the non-elderly group. The POHS of elderly group was significantly longer than non-elderly group.ConclusionLPD may be a safe and feasible procedure for elderly patients and is associated with short POHS.

BackgroundAccording to the international guidelines, patients affected by interstitial lung disease with unusual clinical presentation and radiological findings that are not classic for usual interstitial pneumonia end up meeting criteria for surgical lung biopsy, preferably performed with video-assisted thoracic surgery. The growing appeal of non-intubated thoracic surgery has shown the benefits in several different procedures, but the strict selection criteria of candidates are often considered a limitation to this approach. Although several authors define obesity as a contraindication for non-intubated thoracoscopic surgery, the assessment of obesity as a dominant risk factor represents a topic of debate when minor tubeless procedures such as lung biopsy are considered. Our study aims to investigate the impact of obesity on morbidity and mortality in non-intubated lung biopsy patients with interstitial lung disease, analyzing the efficacy and safeness of this procedure.Materials and MethodsThe study group of 40 obese patients consecutively collected from 202 patients who underwent non-intubated lung biopsy was compared with overweight and normal-weight patients, according to their body mass index. Post-operative complications were identified as the primary endpoint. The other outcomes explored were the early 30-day mortality rate and intraoperative complications, length of surgery, post-operative hospitalization, patient's pain feedback, and diagnostic yield.ResultsThe overall median age of the patients was 67.4 years (60, 73.5). No 30-day mortality or significant differences in terms of post-operative complications (P = 0.93) were noted between the groups. The length of the surgery was moderately longer in the group of obese patients (P = 0.02). The post-operative pain rating scale was comparable among the three groups (P = 0.45), as well as the post-operative length of stay (P = 0.96). The diagnosis was achieved in 99% of patients without significant difference between groups (P = 0.38).ConclusionOur analysis showed the safety and efficacy of surgical lung biopsy with a non-intubated approach in patients affected by lung interstitiopathy. In the context of perioperative risk stratification, obesity would not seem to affect the morbidity compared to normal-weight and overweight patients undergoing this kind of diagnostic surgical procedure.

Published: March 2022

BackgroundMounting studies reveal the relationship between inflammatory markers and post-therapy prognosis. Yet, the role of the systemic inflammatory indices in preoperative microvascular invasion (MVI) prediction for hepatocellular carcinoma (HCC) remains unclear.Patients and MethodsIn this study, data of 1,058 cases of patients with HCC treated in the First Affiliated Hospital of Sun Yat-sen University from February 2002 to May 2018 were collected. Inflammatory factors related to MVI diagnosis in patients with HCC were selected by least absolute shrinkage and selection operator (LASSO) regression analysis and were integrated into an “Inflammatory Score.” A prognostic nomogram model was established by combining the inflammatory score and other independent factors determined by multivariate logistic regression analysis. The receiver operating characteristic (ROC) curve and the area under the curve (AUC) were used to evaluate the predictive efficacy of the model.ResultsSixteen inflammatory factors, including neutrophil-to-lymphocyte ratio, platelet-to-lymphocyte ratio, etc., were selected by LASSO regression analysis to establish an inflammatory score. Multivariate logistic regression analysis showed that inflammatory score (OR = 2.14, 95% CI: 1.63–2.88, p &lt; 0.001), alpha fetoprotein (OR = 2.02, 95% CI: 1.46–2.82, p &lt; 0.001), and tumor size (OR = 2.37, 95% CI: 1.70–3.30, p &lt; 0.001) were independent factors for MVI. These three factors were then used to establish a nomogram for MVI prediction. The AUC for the training and validation group was 0.72 (95% CI: 0.68–0.76) and 0.72 (95% CI: 0.66–0.78), respectively.ConclusionThese findings indicated that the model drawn in this study has a high predictive value which is capable to assist the diagnosis of MVI in patients with HCC.

Rising Above Misinformation and Deepfakes
Authors: Veerasamy Namosha , Pieterse Heloise 
Published: March 2022

Misinformation can be rapidly spread in cyberspace. It thrives in the social media landscape as well as news platforms. Misinformation can readily gain momentum in the race to influence people or intentionally deceive. With the use of bots, misinformation can be easily shared, especially in environments like Twitter and Facebook. While, some measures are taken to stop the spread of misinformation, threats like Deepfakes are posing a higher challenge. Deepfakes provide a means to generate fake digital content in order to impersonate a person. With the use of audio, images and videos, artificial intelligence is used to depict the speech and actions of people. Deepfakes are typically made of presidents or influential businessmen such as Donald Trump and Mark Zuckerberg. Deep Fakes can be very realistic and convincing as this form of synthetic media is raising concerns about its possible misuse. The effects of Deepfakes are to spread disinformation, confuse users or create influence. This can lead to further effects like political factions, blackmail, harassment and extortion. Deepfakes could lead to a distrust in digital content as many may feel that anything we see is actually just a manipulation. Deepfakes has arisen as a new generation of misinformation through the manipulation of digital media in order to create realistic videos. This paper looks at the governing, communal and technical issues relating to Deepfakes. At the technical level, the use of audio and text analysis used to create Deepfake videos is advancing at a rapid pace which has also made its affordability and accessibility easier. An evaluation of the threats stemming from Deepfakes reveals that there are various mental, monetary and group dynamics involved. In this paper, the various types of threats emanating from Deepfakes is discussed. This paper also looks at five factors in the field of Deepfakes that should be taken into consideration (Technical Source Dissemination Victim Viewers). The paper discussed these five factors in order to help identify measures to help curb the spread of Deepfakes. A combination of these measures can help limit the spread of Deepfakes and support mitigation of the threat. Due to prominence and power that digital media has, it is imperative that this threat not be overlooked. The paper provides a holistic approach to understanding the risk and impact of Deepfakes, as well measures to help mitigate abuse thereof.

Memory Forensics is one of the most important emerging areas in computer forensics. In memory forensics, analysis of userland memory is a technique that analyses per-process runtime data structures and extracts significant evidence for application-specific investigations. In this research, our focus is to examine the critical challenges faced by process memory acquisition that can impact object and data recovery. Particularly, this research work seeks to address the issues of consistency and reliability in userland memory forensics on Android. In real-world investigations, memory acquisition tools record the information when the device is running. In such scenarios, each application’s memory content may be in flux due to updates that are in progress, garbage collection activities, changes in process states, etc. In this paper we focus on various runtime activities such as garbage collection and process states and the impact they have on object recovery in userland memory forensics. The outcome of the research objective is to assess the reliability of Android userland memory forensic tools by providing new research directions for efficiently developing a metric study to measure the reliability. We evaluated our research objective by analysing memory dumps acquired from 30 apps in different Process Acquisition Modes. The Process Acquisition Mode (PAM) is the memory dump of a process that is extracted while external runtime factors are triggered. Our research identified an inconsistency in the number of objects recovered from analysing the process memory dumps with runtime factors included. Particularly, the evaluation results revealed differences in the count of objects recovered in different acquisition modes. We utilized Euclidean distance and covariance as the metrics for our study. These two metrics enabled the authors to identify how the change in the number of recovered objects in PAM impact forensic analysis. Our conclusion revealed that runtime factors could on average result in about 20% data loss, thus revealing these factors can have an obvious impact on object recovery.
