Abstract
PURPOSE Bevacizumab has evolved as an integral treatment option for patients with high-grade gliomas. Little is known about clinical risk factors that predispose patients with high-grade gliomas receiving bevacizumab to VTE or ICH. We sought to characterize the clinical risk factors associated with risk of either event. METHODS In this multi-institutional retrospective study, we first evaluated patients with high-grade gliomas who were treated with bevacizumab at University of Texas MD Anderson Cancer Center from 2015-2021. We compared clinical and treatment-related factors among three cohorts: those who developed VTE, ICH, or neither. We further compared survival outcomes of these patients from the time of bevacizumab initiation. Then to further confirm our results in a non-cancer center hospital setting we evaluated patients from two Ascension Seton Hospitals in Austin, Texas which are affiliated with Dell Medical School at the University of Texas at Austin from 2017-2022. RESULTS We found that the presence of cerebral macrobleeding, defined as a magnetic susceptibility of > 1 cm3 on magnetic resonance imaging, was highly associated with risk of developing ICH after initiation of bevacizumab. Development of ICH was significantly associated with poorer survival outcomes. We did not find a statistically significant effect of VTE on survival after bevacizumab initiation. CONCLUSION In order to stratify the risk for developing ICH before the initiation of bevacizumab, we recommend to assess for the presence of cerebral macrobleeding as it is associated with ICH development.

Abstract
PURPOSE Cancer is an independent risk factor for the development of venous thromboembolism (VTE). However, patients with high-grade glioma (HGG) including glioblastoma (GBM) are at a particularly high risk of VTE with an incidence up to 20-30% per year. Patients are often placed on anticoagulation if they are found to have VTE. However, patients with primary brain tumors such as HGG are at increased risk for intracerebral hemorrhage (ICH) even without the administration of anticoagulation. The combination of risk factors for ICH with anticoagulation and HGG complicates decision-making. Currently it is not known which of the direct oral anticoagulants (DOACs) are safest for patients with HGG in terms of adverse bleeding-related outcomes such as ICH. Furthermore, a deeper understanding of the clinical and molecular determinants of bleeding-related adverse outcomes in HGG is not fully characterized. METHODS In this retrospective study, we identified and gathered data on 75 consecutive patients with pathology-confirmed HGG with hospital encounters at two academic medical center hospitals in Austin between July 1, 2017 and June 30, 2022. We compared clinical and treatment-related factors among cohorts who had received various forms of anticoagulation or no anticoagulation. RESULTS Patients who were on rivaroxaban (3/7 (43%)) had a statistically significant association with more bleeding-related adverse events compared to those on apixaban (0/12 (0%)) or enoxaparin (0/5 (0%), p = 0.022) even though the groups were similar in characteristics including total time on the respective anticoagulation. Patients on anticoagulation vs those never on anticoagulation did not differ in terms of their studied demographic and clinical characteristics. Intriguingly, logistic regression analysis revealed that patients Astrocytoma, isocitrate dehydrogenase (IDH) mutant, grade 4 had a significant association with more adverse bleeding-related events even when controlling for other relevant factors (Odds Ratio compared to reference GBM: 49.4, 95% CI: 2.8, 2084.7; p = 0.013). CONCLUSION In this study we found that the use of rivaroxaban was associated with more bleeding-related events compared to apixaban and enoxaparin in patients with high-grade glioma. In this study we also found that the diagnosis of astrocytoma, IDH mutant, grade 4 was associated with more bleeding events. However, this is based on a small study and there is a need for larger studies to further evaluate these results.

Abstract
Diffuse infiltrating low-grade glioma (LGG) is classified as WHO grade 2 astrocytoma with isocitrate dehydrogenase (IDH) mutation and oligodendroglioma with IDH1 mutation and 1p/19q codeletion. Despite their better prognosis compared with glioblastoma, LGGs invariably recur, leading to disability and premature death. There is an unmet need to discover new therapeutics for LGG, which necessitates preclinical models that closely resemble the human disease. Basic scientific efforts in the field of neuro-oncology are mostly focused on high-grade glioma, due to the ease of maintaining rapidly growing cell cultures and highly reproducible murine tumors. Development of preclinical models of LGG, on the other hand, has been difficult due to the slow-growing nature of these tumors as well as challenges involved in recapitulating the widespread genomic and epigenomic effects of IDH mutation. The most recent WHO classification of CNS tumors emphasizes the importance of the role of IDH mutation in the classification of gliomas, yet there are relatively few IDH-mutant preclinical models available. Here, we review the in vitro and in vivo preclinical models of LGG and discuss the mechanistic challenges involved in generating such models and potential strategies to overcome these hurdles.

Abstract
Abstract
Aim
The recent shift from traditional surgical teaching to the incorporation of simulation training in plastic surgery has resulted in the development of a variety of simulation models and tools. We aim to identify all currently available simulators and tools for plastic surgery, assess their validity and establish their effectiveness.
Method
MEDLINE and Embase were searched for articles which validate simulation models in plastic surgery. Each study was screened in accordance with the Messick validity framework, and a rating was given for each section. In order to determine the effectiveness of each study, the McGaghie model of translational outcomes was used.
Results
On screening 2104 articles, 71 were identified to discuss validity and effectiveness. Only one study was found to achieve a high score in all validity parameters and no studies achieved an effectiveness level >2.
Conclusions
With the increasing amount of simulation training tools, there must be more validity studies conducted using updated validity frameworks. In addition, there should be an increased emphasis of the relationship between these simulators and patient outcomes/surgical technique in the operating theatre in order to determine translational outcomes. More training tools evaluating both technical and nontechnical surgical skills are recommended.

Abstract
Duodenal inversum is a rare disease not frequently encountered in clinical practice. The diagnosis is usually made late due to its rarity. Many other causes of abdominal pain like ulcer disease, pancreatitis, malrotation are mostly thought of initially and the diagnosis is usually missed. Only a few cases of duodenal inversum present with outlet obstruction. Duodenojejunostomy is perhaps the ideal management for duodenal inversum if the patient presents with outlet obstruction. Our intention is to create awareness of such a rare disease with an available definitive treatment option in the form of minimally invasive surgery. One such case of a 31-year-old man is described that was successfully managed by laparoscopic duodenojejunostomy.

Abstract
Glioblastoma (GBM) is highly resistant to chemo- and immune-based therapies and targeted inhibitors. To identify novel drug targets, we screened orthotopically implanted, patient-derived glioblastoma sphere-forming cells (GSCs) using an RNAi library to probe essential tumor cell metabolic programs. This identified high dependence on mitochondrial fatty acid metabolism. We focused on medium-chain acyl-CoA dehydrogenase (MCAD), which oxidizes medium-chain fatty acids (MCFAs), due to its consistently high score and high expression among models and upregulation in GBM compared to normal brain. Beyond the expected energetics impairment, MCAD depletion in primary GBM models induced an irreversible cascade of detrimental metabolic effects characterized by accumulation of unmetabolized MCFAs, which induced lipid peroxidation and oxidative stress, irreversible mitochondrial damage, and apoptosis. Our data uncover a novel protective role for MCAD to clear lipid molecules that may cause lethal cell damage, suggesting that therapeutic targeting of MCFA catabolism could exploit a key metabolic feature of GBM.

Abstract
Abstract
Introduction
We assessed whether expert mentoring improved the rate of uptake of robotic surgical skill and whether general advanced psychomotor ability (PMA), and specific video-game experience (VGE) had any impact on robotic surgical skill.
Method
Twenty robotically naive medical students were blinded and randomised to two cohorts; control (CC) and intervention (IC). Each student's initial performance on a variety of da Vinci Skills Simulator (dVSSim) exercises was measured and then reassessed following an independent practice (CC) or mentor guided practice session (IC). Outcome metrics were overall score, time to completion, economy of motion and master workspace range. Quantitative, questionnaire data was collected to evaluate the relationship between robotic surgical skill, PMA and VGE. Statistical analysis was performed with SPSS software utilising the independent t-test.
Result
On average, overall score for CC improved by 16.8% compared to 43.3% for the IC (p=0.04). Time to completion improved by 26.2% (CC) vs. 40% (IC), economy of motion by 16.5% vs. 25% and master workspace range by 8% vs. 11%. PMA correlated with better initial performances for all metrics, especially for overall score (p=0.003) and economy of motion (p=0.03). Students with more VGE had overall scores that were on average 20% better than those with little or no experience and this relationship was also seen for economy of motion and master workspace range.
Conclusion
Expert mentoring leads to a greater improvement in performance than independent practice alone. Advanced PMA correlates with greater innate robotic skill, as does VGE, but to a lesser extent.
Take-home message
1) Expert mentoring leads to a greater improvement in performance than independent practice alone. 2) Advanced PMA correlates with greater innate robotic skill, as does VGE, but to a lesser extent.

Abstract
Abstract
There is a tremendous need to identify new genetic drivers of glioblastoma which can serve as potential therapeutic targets. In order to find new drivers, we leveraged genomic datasets to conduct a context specific in vivo functional genomic screen of overexpressed and/or amplified genes in GBM. We identified WISP1, a secreted extracellular matrix protein, to be an overexpressed driver in GBM. Overexpression of WISP1 was able to drive tumor growth in various in vivo models. Knockdown of WISP1 with shRNAs resulted in reduced colony formation in vitro and reduced tumor growth in vivo. Rescue experiments validated that the shRNAs were on target. Functional characterization of the protein revealed that the TSP module is necessary for the phenotype. Intriguingly, overexpression of WISP1 lacking the signal peptide module for secretion resulted in a strong phenotype. Co-culture and conditioned medium experiments further supported a secretion independent intracellular role of WISP1 in GBM. Though WISP1 is a secreted protein we have found some basal localization in the cytosol. Overall, we have revealed WISP1 to be a driver of GBM with possible therapeutic potential as a target. This study has expanded our understanding of WISP1 by supporting a new role as a driver in GBM which can function in a non-canonical manner in the cytosol. Overall, we have revealed WISP1 to be a driver of GBM with possible therapeutic potential as a target.

Abstract
Immunotherapy has changed the landscape of treatment of many solid and hematological malignancies and is at the forefront of cancer breakthroughs. Several circumstances unique to the central nervous system (CNS) such as limited space for an inflammatory response, difficulties with repeated sampling, corticosteroid use for management of cerebral edema, and immunosuppressive mechanisms within the tumor and brain parenchyma have posed challenges in clinical development of immunotherapy for intracranial tumors. Nonetheless, the success of immunotherapy in brain metastases (BMs) from solid cancers such as melanoma and non-small cell lung cancer (NSCLC) proves that the CNS is not an immune-privileged organ and is capable of initiating and regulating immune responses that lead to tumor control. However, the development of immunotherapeutics for the most malignant primary brain tumor, glioblastoma (GBM), has been challenging due to systemic and profound tumor-mediated immunosuppression unique to GBM, intratumoral and intertumoral heterogeneity, low mutation burden, and lack of stably expressed clonal antigens. Here, we review recent advances in the field of immunotherapy for neuro-oncology with a focus on BM and GBM.

Abstract
Rice is the foremost staple food in the world, safeguarding the global food and nutritional security. Rise in atmospheric carbon dioxide (CO2) and water deficits are threatening global rice productivity and sustainability. Under real field conditions these climatic factors often interact with each other resulting in impacts that are remarkably different compared to individual factor exposure. Rice soils exposed to drought and elevated CO2 (eCO2) alters the biomass, diversity and activity of soil microorganisms affecting greenhouse gas (GHG) emission dynamics. In this review we have discussed the impacts of eCO2 and water deficit on agronomic, biochemical and physiological responses of rice and GHGs emissions from rice soils. Drought usually results in oxidative stress due to stomatal closure, dry weight reduction, formation of reactive oxygen species, decrease in relative water content and increase in electrolyte leakage at almost all growth and developmental phases of rice. Elevated atmospheric CO2 concentration reduces the negative effects of drought by improving plant water relations, reducing stomatal opening, decreasing transpiration, increasing canopy photosynthesis, shortening crop growth period and increasing the antioxidant metabolite activities in rice. Increased scientific understanding of the effects of drought and eCO2 on rice agronomy, physiology and GHG emission dynamics of rice soil is essential for devising adaptation options. Integration of novel agronomic practices viz., crop establishment methods and alternate cropping systems with improved water and nutrient management are important steps to help rice farmers cope with drought and eCO2. The review summarizes future research needs for ensuring sustained global food security under future warmer, drier and high CO2 conditions.

Abstract
INTRODUCTION Over 80,000 oral cancer cases get diagnosed each year in India, majority undergoing extensive resections owing to their late presentation. Pectoralis major myocutaneous (PMMC) flap is a pedicled axial pattern flap which is based on thoracoacromical artery. It is readily available as a viable alternative to free flap reconstruction, especially for the economically poor and malnourished patients. Its proximity to head and neck structures gives added advantage to reconstruct complex and large volume oral and maxillofacial defects. It provides a relatively good possibility of functional and aesthetic restoration providing both mucosal lining and skin cover. MATERIALS AND METHODS This was a prospective observational study of 29 PMMC flap reconstructions, conducted between 2013-2016. The reconstruction outcomes assessed in this study were divided into two categories namely "success" and "failure" based on certain functional parameters observed during follow-up of 1 year. The complications were broadly classified as major/minor and flap related/non-flap related. We assessed the feasibility of using a PMMC flap for reconstructing various subsites of oral cavity cancer. Further, the association of patient variables with complication rates and outcome of reconstruction were analysed. RESULTS Out of 29 patients overall complications were noted in 15 (51.7%) cases with a female preponderance. Flap-related complications were noted in 9 whereas non-flap-related complications were seen in 6 patients. Major and minor complications were noted in 2 (both flap related) and 13 cases respectively. Complete full thickness flap necrosis was not encountered in any patient. Patients with flap skin paddle size ≤ 36 cm2 (n = 12) had significantly increased overall complication rates. Despite complications a high success rate (93.1%, n = 27) was achieved with this mode of reconstruction. CONCLUSION The PMMC flap reconstruction is a versatile, reliable and an affordable single staged procedure with a high success rate in terms of achieving treatment goals. Although it has moderately high complication rates, but PMMC flap proved to be a workhorse in locally advanced cases of head and neck cancer at the end of 1 year follow-up.

Abstract
INTRODUCTION Laparoscopic radical nephrectomy(LRN) is a cornerstone in managing renal cancer and small renal masses. Twenty-first century surgical training faces challenges, thus must be efficient and safe so surgeons attain relevant skills, protecting patients and operative outcomes. This study aimed to systematically develop a tool for training and assessment in LRN and validate the developed tool for use by trainee urologists. METHODS This prospective, longitudinal, multi-institutional study was undertaken from September 2014 - June 2015. Healthcare Failure Mode and Effect Analysis was utilised for development and followed by validation where the assessment tool was distributed to five specialists to increase content validity. Four experts were observed as a multi-institutional approach. Hand-assisted, transperitoneal and retroperitoneal approaches were considered. RESULTS The LRN Assessment Tool comprised four phases, 17 processes, 41 sub-processes. Four surgeons and operating teams were observed across four hospitals for 19.5hours (5.75h hand-assisted, 8.75h trans-peritoneal, 5h retro-peritoneal). After hazard analysis, three checklists were constructed. Those for hand-assisted LRN and transperitoneal LRN contained four phases, 20 processes, 33 sub-processes and that for retroperitoneal LRN contained four phases, 20 processes, 30 sub-processes. These were merged to form one assessment tool. The final result was a four phase LRN Assessment Tool with 17 processes, 41 sub-processes. All participants agreed the final LRN Assessment Tool included pertinent steps. CONCLUSIONS The LRN Assessment Tool was developed using Healthcare Failure Mode and Effect Analysis risk analysis to ensure hazardous procedural sub-steps were included. Validation ascertained important processes were not overlooked. Full application through a pilot study must be undertaken.

Abstract
BACKGROUND Sella turcica, the bony depression located in sphenoid bone houses and protects the pituitary gland. Formation and development of the sella turcica and teeth share, in common, the involvement of neural crest cells. The anterior part of the sella turcica is believed to develop mainly from neural crest cells, and dental epithelial progenitor cells differentiate through sequential and reciprocal interaction with neural crest-derived mesenchyme. Thus, any structural deviations in the sella, like bridging or roofing, are believed to be related to specific deviations in the facial skeleton and dental anomalies. Until now, there have been no studies concerning the prevalence of sella turcica bridging in skeletal Class II subjects. OBJECTIVE The aim of this study was to analyse the prevalence of sella turcica bridging in subjects with class I and class II skeletal types and to check whether sella can be considered as diagnostic marker for skeletal class II malocclusion. MATERIALS AND METHODS Lateral cephalometric images of 205 subjects in the age range of 13 to 25 years were retrospectively analysed and classified for the type of skeletal malocclusion and the radiographs were evaluated for the prevalence of bridging of the sella in these subjects. RESULTS The results show significance in the prevalence of sella turcica bridging (partial/complete) among subjects with skeletal class II malocclusion.

Abstract
INTRODUCTION Cognitive training is an important training modality which allows the user to rehearse a procedure without physically carrying it out. This has led to recent interests to incorporate cognitive training within surgical education but research is currently limited. The use of cognitive training in surgery is not clear-cut and so this study aimed to determine whether, relative to a control condition, the use of cognitive training improves technical surgical skills on a ureteroscopy simulator, and if so whether one cognitive training method is superior. METHODS This prospective, comparative study recruited 59 medical students and randomised them to one of three groups: control- simulation training only (n=20), flashcards cognitive training group (n=20) or mental imagery cognitive training group (n=19). All participants completed three tasks at baseline on the URO Mentor simulator followed by the cognitive intervention if randomised to receive it. Participants then returned to perform an assessment task on the simulator. Outcome measures from the URO Mentor performance report was used for analysis and a quantitative survey was given to all participants to assess usefulness of training received. RESULTS This study showed cognitive training to have minimal effects on technical skills of participants. The mental imagery group had fewer laser misfires in the assessment task when compared to both control and flashcards group (P=.017, P=.036, respectively). The flashcards group rated their preparation to be most useful when compared to control (P=.0125). Other parameters analysed between the groups did not reach statistical significance. Cognitive training was found to be feasible and cost effective when carried out in addition to simulation training. CONCLUSION This study has shown that the role of cognitive training within acquisition of surgical skills is minimal and that no form of cognitive training was superior to another. Further research needs to be done to evaluate other ways of performing cognitive training.

Abstract
The KHP PCaBB was established in 2013 and recruits donors from the Urology or Oncology Departments at Guy's Hospital in London (UK). Prostate cancer patients may be approached to give their consent for biobanking at any point in their treatment pathway, which allows residual material from their earlier diagnosis to be transferred and used by the Biobank. Currently, patients are specifically asked to donate samples of blood and surplus prostate tissue as well as permitting access to their clinical and pathological data that continues to be added throughout the course of their disease. Between 2013 and 2015, 549 prostate cancer patients gave their consent to the biobank and, the tissue repository collected 489 blood samples, 120 frozen prostate tissue samples and 1064 formalin fixed paraffin embedded diagnostic blocks.Prostate cancer has become a chronic disease in a large proportion of men, with many men receiving multiple subsequent treatments, and their treatment trajectory often spanning over decades. Therefore, this resource aims to provide an ideal research platform to explore potential variations in treatment response as well as disease markers in the different risk categories for prostate cancer.A recent audit of the KHP PCaBB revealed that between 2013 and 2015, 1796 patients were diagnosed with prostate cancer at King's Health Partners (KHP), out of which 549 (30.6%) gave their consent to KHP PCaBB. Comparisons between demographic and clinical characteristics of patients who had consented compared to the total patient population revealed that the KHP PCaBB is demographically representative of the total prostate cancer patient population seen in Guy's and St Thomas' NHS Foundation Trust (GSTT). We observed no differences in distribution of ethnicity (p = 0.507) and socioeconomic status (p = 0.097). Some differences were observed in clinical characteristics, specifically with treatment type - which differed significantly between the patients who had given consent and total patient population.The KHP PCaBB has thereby amassed a rich data and tissue repository that is largely reflective of both the demographic and clinical diversity within the total prostate cancer patient population seen at KHP, making it an ideal platform for prostate cancer research.

Abstract
BACKGROUND Median maxillary labial frenum (MMLF) appears as a fold of mucous membrane extending from the lining of the mucous membrane of the lips towards the crest of the alveolar ridge on the labial surface. MMLF can demonstrate certain variations in their shape, size and position, both among individuals and within the same individual at different ages. Many clinicians, not being aware of the normal variations of median maxillary labial frenum misinterpret them as pathological entities. OBJECTIVES The objectives of the study were to determine the prevalence of morphologic variations of MMLF, to classify the morphological variations of MMLF on the basis of their location on the frenum and to compare the morphological variations of MMLF among different age groups and genders. MATERIALS AND METHODS The study was conducted on 700 males and 700 females of age 5 to 74 yrs, chosen randomly. They were equally divided on the basis of age into 7 groups, each group having equal gender distribution. The morphological variations of MMLF were classified according to Sewerin's classification and the attachments on the freni were further sub-classified. RESULTS The commonest type of frenum was found to be the simple type, whereas bifid frenum was not found at all. Statistically significant difference was found in proportion of types of frenum among the different age groups and also in proportion of types of frenum among the different sites of presence of frenal attachments. No statistically significant difference was found in proportion of types of frenum in male and female subjects. CONCLUSION This study shows that MMLF presents with an array of morphological variations. These morphological variations may sometimes pose a complicating factor in maintaining oral hygiene, speech, mastication, esthetics, denture construction, etc. Hence, appropriate recognition of frenal variations and subsequent modification of treatment procedures are essential for a successful outcome of therapy.

Abstract
The landscape of the surgical management of urologic malignancies has dramatically changed over the past 20 years. On one side, better diagnostic and prognostic tools allowed better patient selection and more reliable surgical planning. On the other hand, the implementation of minimally invasive techniques and technologies, such as robot-assisted laparoscopy surgery and image-guided surgery, allowed minimizing surgical morbidity. Ultimately, these advances have translated into a more tailored approach to the management of urologic cancer patients. Following the paradigm of "precision medicine", contemporary urologic surgery has entered a technology-driven era of "precision surgery", which entails a range of surgical procedures tailored to combine maximal treatment efficacy with minimal impact on patient function and health related quality of life. Aim of this non-systematic review is to provide a critical analysis of the most recent advances in the field of surgical uro-oncology, and to define the current and future role of "precision surgery" in the management of genitourinary cancers.

Abstract
Laparoscopic surgeons perform precise and time consuming procedures while holding awkward poses in their upper body and arms. There is an ongoing effort to produce robotic tools for laparoscopic surgery that will simplify these tasks and reduce risk of errors to help both the surgeon and the patient. STIFF-FLOP is an ongoing EU FP7 project focusing on this by creating a stiffness controllable soft robotic manipulator. This paper reports on a study to test the soft manipulator's learnability and the effort associated with its use. The tests involved a limited prototype of the manipulator with a custom built test rig and EMG acquisition system. Task times and video recordings along with EMG waveforms from the forearm muscles of participants (n=25) were measured for objective assessment. A questionnaire was also provided to the participants for subjective assessment. The data shows that in average EMG levels were 25.9% less in RMS when using the STIFF-FLOP arm than when conventional laparoscopic tools were used. In terms of learnability, from the first to the second attempt on the STIFF-FLOP manipulator, elapsed time was reduced by an average of 32.1%. Further details and analysis of the EMG signals as well as time and questionnaire results is presented in the paper.

Abstract
BACKGROUND The effect of artificial sweetener consumption on cancer risk has been debated in animal models for over four decades. To further investigate this relationship, this study aims to synthesise results from several of the most recent studies in humans. METHODS An online literature search was performed in MEDLINE from 2003 to 2014 using Ovid, PubMed, Web of Science, and Scopus using keywords 'artificial', 'sweetener' and 'cancer'. Ninety-two results were then manually assessed for eligibility. Studies were included if the relationship between artificial sweeteners and cancer was their central hypothesis, and if they adjusted for age, gender, smoking status and body mass index. Extracted data included study design, patient characteristics, outcome measure and results. RESULTS In the five publications that satisfied the inclusion criteria, significant direct associations with artificial consumption were found for laryngeal (odds ratio, OR 2.34, 95% CI: 1.20-4.55), urinary tract tumours (OR 2.12, 95% CI: 1.22-3.89), non-Hodgkin lymphoma in men (RR 1.31, 95% CI: 1.01-1.72), multiple myeloma in men (RR 2.02, 95% CI: 1.20-3.40) and leukaemia (RR 1.42, 95% CI: 1.00-2.02). Inverse relationships were found in breast (OR 0.70, 95% CI: 0.54-0.91, p trend = 0.015) and ovarian (OR 0.56, 95% CI: 0.38-0.81, p trend < 0.001) cancers. CONCLUSION The statistical value of this review is limited by the heterogeneity and observational designs of the included studies. Although there is limited evidence to suggest that heavy consumption may increase the risk of certain cancers, overall the data presented are inconclusive as to any relationship between artificial sweeteners and cancer.

Abstract
Primary peritoneal papillary serous carcinoma is a rare primary malignancy diffusively involving the peritoneum of abdomen and pelvis. Epithelial ovarian cancers and primary peritoneal cancers arise from the common germinal epithelium which develops from the coelomic epithelium. Due to a common embryonic origin of the ovary and the peritoneum, carcinoma of the ovary and primary peritoneal carcinoma have much histological similarity. However the incidence of Primary peritoneal serous carcinoma is considerably lower than that of epithelial ovarian cancer and is mostly seen in elderly women. Early stages of this disease may be asymptomatic; symptoms of the advance stages of the disease include abdominal distention, abdominal lump, non-specific abdominal pain, vomiting and dyspnoea all as a result of massive ascites. Patients diagnosed with primary peritoneal papillary serous carcinoma are treated using the same staging, surgical and chemotherapeutic approach as epithelial ovarian cancer because of the similarities in biological behavior.

Abstract
The aim of this paper was to examine the eligibility criteria, surveillance protocols and oncological outcomes of published active surveillance (AS) series. We also assessed the evidence for utility of novel tools for optimal risk stratification and surveillance of men suitable for AS. A non-systematic literature search of the Medline, Embase, and Scopus databases was performed in April 2015 using medical subject headings and free-text protocol. The search was conducted by applying free-text protocol with the following search terms: "active surveillance", "prostate cancer", "prostatic neoplasm", "watchful waiting", "low risk prostate cancer" and "very low risk prostate cancer". The definition of insignificant disease remains debatable as criteria for patient selection vary among studies. Tools for better selection of candidates and monitoring of the disease process have evolved since the conception of AS, including new biomarkers like phi, mpMRI and alternate biopsy strategies. AS is a sound strategy for reducing overtreatment of men with low-risk, and potentially selected men with intermediate-risk prostate cancer and shorter life expectancy, without compromising overall and cancer specific survival. More data are needed on the optimal integration of the new tools on AS paradigms and on the long-term health impact of AS in different populations.

Abstract
The use of robots in orthopaedic surgery is an emerging field that is gaining momentum. It has the potential for significant improvements in surgical planning, accuracy of component implantation and patient safety. Advocates of robot-assisted systems describe better patient outcomes through improved pre-operative planning and enhanced execution of surgery. However, costs, limited availability, a lack of evidence regarding the efficiency and safety of such systems and an absence of long-term high-impact studies have restricted the widespread implementation of these systems. We have reviewed the literature on the efficacy, safety and current understanding of the use of robotics in orthopaedics.
