Abstract
Background: To evaluate the use of laparoscopic-assisted transanal and total mesorectal excision (Ta-TME) in men with difficult pelvic anatomy in an attempt to optimize anal sphincteric preservation, determine the completeness of TME, and determine postoperative morbidity and mortality.Methods: Twenty male patients (TA group) with difficult pelvic anatomy (narrow pelvis) who were diagnosed with rectal cancer underwent Ta-TME surgery from January 2017 to January 2018 at Peking University Cancer Hospital. We matched these 20 patients with 2 other groups of patients who underwent either a laparoscopic transabdominal TME (LA group) or an open transabdominal TME (OP group) according to age, sex, BMI, distance of tumour from the anal verge, and diameter of the tumour. All 3 groups of patients had undergone preoperative neoadjuvant chemoradiation therapy. The efficacy and safety of Ta-TME were evaluated according to operative time, blood loss, postoperative hospital stay, and postoperative complications. Outcomes of Ta-TME were evaluated by comparing the rate of a positive circumferential resection margin, the integrity of the TME, and the rate of sphincter preservation among the 3 groups.Results: When comparing Ta-TME (TA group), laparoscopic transabdominal TME (LA group), and open transabdominal TME (OP group), the respective mean blood loss (100 mL, 100 mL, 100 mL, p=0.335), postoperative hospital stay (9 days, 9 days, 7 days), number of harvested lymph nodes (7, 6, 7), positive circumferential resection margin rate (0%, 0%, 5%), rate of pathologic complete response (5%,10%,10%), and integrity of TME showed no significant differences across groups (p>0.5 for all). In contrast, there were significant differences in operation time (302 min, 253 min, 135 min), rate of preservation of the anal sphincter (100%, 30%, 45%), and the creation of a protective diverting ileostomy (100%, 30%, 45%, p<0.05 for all).Conclusion: The rate of anal sphincter preservation in the Ta-TME group was considerably greater than that in the other groups, but the safety of the operation did not differ among the 3 groups. Ta-TME required a diverting ileostomy in all cases, and the total operation time for Ta-TME was greater than that of laparoscopic and open transabdominal TME.

Abstract
Background: Assessing the fidelity of an implementation strategy is important to understand why and how the strategy influences the uptake of evidence-based interventions. The present study aims to assess the fidelity of the two procedures for engaging primary care (PC) professionals and for the deployment of an implementation strategy for optimizing type 2 diabetes prevention in routine PC within the PREDIAPS randomized cluster implementation trial. Method: We conducted a mixed-method fidelity evaluation study of the PREDIAPS implementation strategy. Nine PC centers from the Basque Health Service (Osakidetza) were allocated to two different procedures to engage physicians and nurses and deploy a implementation strategy to model and adapt the clinical intervention and its implementation to their specific contexts: a Global procedure, promoting the cooperation of all healthcare professionals from the beginning; or a Sequential procedure, centered first on nurses who then pursued the pragmatic cooperation of physicians. Process indicators of the delivery and receipt of implementation strategy actions, documented modifications to the planned implementation strategy, and a structured group interview with centers’ leaders were used to assess the following components of fidelity: adherence, dose, quality of delivery, professionals’ responsiveness and program differentiation. Results: Generally, the procedures compared for professionals engagement and deployment of the implementation strategy were carried out with the planned differentiation. Nonetheless, some unexpected between-group differences were observed, the initial rate of collaboration of nurses being higher in the Sequential (93%) than in the Global (67%) groups. Exposure rate to the programed implementation actions (% of hours received out of those delivered) were similar in both groups by professional category, with nurses (86%) having a higher rate of exposure than physicians (75%). Professionals identified half of the planned discrete strategies and their rating of strategies’ perceived usefulness was overwhelmingly positive, with few differences between Sequential and Global centers. Conclusions The PREDIAPS implementation strategy has been implemented with high fidelity and minor unplanned reactive modifications. Professionals’ exposure to the implementation strategy was high in both groups. The centers’ organizational context (i.e., work overload) led to small mismatches between groups in participation and exposure of professionals to implementation actions.

Abstract
Background: Liver metastasis (LIM) of gastrointestinal stromal tumor (GIST) is associated with poor prognosis. The present study aimed at developing and validating nomogram to predict LIM in patients with GIST, thus helping clinical diagnosis and treatment.Methods: The data of GIST patients derived from Surveillance, Epidemiology, and End Results (SEER) database from 2010 to 2016, which were then screened by univariate and multivariate logistic regression for the construction of LIM nomogram. The model discrimination of LIM nomogram was evaluated by concordance index (C-index) and calibration plots, while the predictive accuracy and clinical values were measured by decision curve analysis (DCA) and clinical impact plot. Furthermore, we validated predictive nomogram in the internal testing set.Results: A total of 3797 patients were enrolled and divided randomly into training and validating groups in a 3-to-1 ratio. After logistic regression, the significant variables were sex, tumor location, tumor size, N stage and mitotic rate. The calibration curves showed the perfect agreement between nomogram predictions and actual observations, while the DCA and clinical impact plot showed the clinical utility of LIM nomogram. C-index of the nomogram was 0.812. What’s more, receiver operating characteristic curves (ROC) also showed good discrimination and calibration in the training set (AUC=0.794, 95% CI: 0.778 to 0.808) and the testing set (AUC=0.775, 95% CI: 0.748 to 0.802).Conclusion: The nomogram for patients with GIST can effectively predict the individualized risk of liver metastasis and provide insightful information to clinicians to optimize therapeutic regimens.
Ciphertext-Policy Attribute-based Encryption with Hidden Sensitive Policy from Keyword Search Techniques in Smarty City

Abstract
Smart city greatly facilitates citizens and generates innumerable data, some of which is very private and sensitive. To protect data from unauthorized users, ciphertext-policy attribute-based encryption (CP-ABE) enables data owner to specify an access policy on encrypted data. However, There are two drawbacks in traditional CP-ABE schemes. On the one hand, the access policy is revealed in the ciphertext so that sensitive information contained in the policy is exposed to anyone who obtains the ciphertext. For example, both the plaintext and access policy of an encrypted recruitment may reveal the company’s future development plan. On the other hand, the decryption time scales linearly with the complexity of the access, which makes it unsuitable for resource-limited end users. In this paper, we propose a CP-ABE scheme with hidden sensitive policy from keyword search (KS) techniques in smart city. Specifically, we introduce a new security model chosen sensitive policy security : two access policies embedded in the ciphertext, one is public and the other is sensitive and fully hidden, only if user’s attributes satisfy the public policy, it’s possible for him/her to learn about the hidden policy, otherwise he/she cannot get any information (attribute name and its values) of it. When the user satisfies both access policies, he/she can obtain and decrypt the ciphertext. Compared with other CP-ABE schemes, our scheme exploits KS techniques to achieve more expressive and efficient, while the access policy of their schemes only work on the “AND-gate” structure or their ciphertext size or decryption time maybe super-polynomial. In addition, intelligent devices spread all over the smart city, so partial computational overhead of encryption of our scheme can be outsourced to these devices as fog nodes, while most part overhead in the decryption process is outsourced to the cloud.Therefore, our scheme is more applicable to end users with resource-constrained mobile devices. We prove our scheme to be selective secure under the decisional bilinear Diffie-Hellman (DBDH) assumption.

Abstract
Oral diseases, place a significant burden on individual and population health. These diseases are largely preventable; health promotion initiatives have been shown to decrease the disease rates. However, there is limited implementation of health promotion in dentistry, this could be due to a number of factors; the ethos and philosophy of dentistry is focused on a curative, individualised approach to oral diseases, confusion around health promotion as a concept. Oral health academics are well placed to implement health promotion, training of these professionals needs to include prevention, as training influences dental practice. However, there is a little understanding about how oral health academics (dental professionals who educate dental and oral health students) view health promotion. The aim of this study is to understand how oral health academics conceptualise health promotion and perceive the barriers and possible opportunities for health promotion implementation in dental practice. Methods: Nominal group technique (NGT), a highly structured face-to-face meeting, was conducted with 24 oral health academics to explore how they conceptualize health promotion and the barriers and opportunities for health promotion in practice. An additional 4 questions were emailed to oral health educators after the NGT meeting to gather additional data, 6 oral health academics were involved. The data was analyzed using thematic analysis. Results: Four board themes were identified: “health education”; “structure of dental practice”; “work in progress”; “collaboration”. The oral health academics in this study discussed health promotion in a holistic way, however, health education and behaviour change were mentioned more than other aspects of health promotion. The structure of dental practice specifically the curative approach that underpins dentistry and the lack of funding, and value placed on health promotion could act as a barrier to health promotion being implemented in practice. There has been a shift towards prevention in dentistry, however the participants acknowledge there needs to be a change in the curative culture of the profession. Collaboration with other health professionals and using a common risk factor approach were the identified opportunities for health promotion practice. Conclusions: Oral health academics have a holistic understanding of health promotion, but still focus more on behavioural approaches which is common within dentistry. For a change to occur in health promotion practice a change in the structure, curative approach and funding model of dentistry is required. Collaboration with other health professionals is an opportunity to be capitalised on. Training of future dental professionals is the perfect place to start to implement the changes and opportunities for health promotion presented in this paper.

Abstract
Background: This study aimed to assess the effect of a 980-nm diode laser following chemomechanical root canal preparation on the severity of post-operative pain (PP) after root canal treatment (RCT). Methods: This study included asymptomatic, single-rooted teeth with a periapical index (PAI) score of 3 or 4. All the patients received RCT, including dressing with calcium hydroxide (Ca(OH) 2 ), during two visits. The patients were randomly divided into two groups ( n : 30): a control group, in which the final irrigation was performed using 5 ml of 2.5% sodium hypochlorite (NaOCI), followed by 5 ml of 17% and ethylenediaminetetraacetic acid (EDTA) and 5 ml of distilled water, and a laser group, in which the root canals were irradiated using a 980-nm diode laser after the final irrigation at both visits. The pain levels after both visits were evaluated using a visual analogue scale (VAS) after 8 h, 24 h, 48 h and 7 d. In addition, the time intervals to medication intake were recorded. The collected data were statistically analysed using the chi-square and Mann–Whitney U test ( p <0.05). Results: The average pain level in the control group 24 h after the first visit was significantly higher than that in the laser group ( p <0.05). The average pain level 24 h and 48 h after the second visit was significantly higher in the control group ( p <0.05). The levels of PP 24 h after the first visit were higher than those after the second visit only in the control group ( p <0.05). After the first visit, analgesic use in the control group was significantly higher after 8 h (40%) and 24 h (23%) as compared with that in the laser group ( p <0.05). Conclusions: Root canal irradiation with a diode laser may reduce PP after RCT in single-rooted teeth with a PAI score of 3 or 4.

Abstract
BackgroundCOVID-19 may predispose pregnant women to higher risks of severe disease and poorer neonatal outcome. Psychological sequalae of this pandemic may pose a greater conundrum than its clinical aspects. It is currently unknown that how pregnant women cope with this global pandemic and its ramifications. The aims of the study are to understand the attitudes and precaution practices of non-infected pregnant women towards the COVID-19 outbreak in Singapore.Methods An online cross-sectional survey of COVID-19 awareness among pregnant women attending antenatal clinics in Singapore was conducted. An internet link was provided to complete an online electronic survey on Google platform using a quick response (QR) code on mobile devices. The online survey consists of 34 questions that were categorized into 4 main sections, namely 1) social demographics 2) attitude on safe distancing measures 3) precaution practices and 4) perceptions of COVID-19. Multiple linear regression analysis was performed to examine women’s precaution practices among six independent socio-demographic variables, including age, ethnicity , education , front-line jobs, history of miscarriage and type of antenatal clinic (general , high risk).ResultsA total of 167 survey responses were obtained over eight weeks from April to June 2020. The majority of women were aged ≤35 years (76%, n=127), were of Chinese ethnicity (55%, n=91), attained tertiary education (62%, n=104) and were not working as frontline staff (70%). Using multiple linear regression models, Malay ethnicity (vs. Chinese, β 0.24; 95% CI 0.04, 0.44) was associated with higher frequency of practicing social distancing. Malay women (β 0.48; 95% CI 0.16, 0.80) and those who worked as frontline staff (β 0.28; 95% CI 0.01, 0.56) sanitized their hands at higher frequencies. Age of ≥36 years (vs. ≤30 years, β 0.24; 95% CI 0.01, 0.46), Malay (vs. Chinese, β 0.27; 95% CI 0.06, 0.48) and Indian ethnicity (vs. Chinese, β 0.41; 95% CI 0.02, 0.80), and attendance at high-risk clinic (vs. general clinic, β 0.20; 95% CI 0.01, 0.39) were associated with higher frequency of staying-at-home.ConclusionSocial demographical factors including age > 36 years old, Malay ethnicity, employment in front line jobs and attendance at high-risk clinics are likely to influence the attitudes and precaution practices among pregnant women towards COVID-19 in Singapore. Knowledge gained from our cross-sectional online survey can better guide clinicians to communicate better with pregnant women. Hence, it is important for clinicians to render appropriate counselling and focused clarification on the effect of COVID-19 among pregnant women for psychological support and mental wellbeing.

Abstract
Background: Methods have been developed for preventing delayed bleeding (DB) after gastric endoscopic submucosal dissection (GESD). However, none of the methods can completely prevent DB. We hypothesized that DB could be prevented by a modified search, coagulation, and clipping (MSCC) method for patients at low risk for DB and by combining the use of polyglycolic acid (PGA) sheets and fibrin glue with the MSCC method (PMSCC method) for patients at high risk for DB (antibleeding [ABI] strategy). This study assessed the technical feasibility of this novel strategy.Methods: We investigated 123 lesions in 121 consecutive patients who underwent GESD in Kushiro Rosai Hospital between April 2018 and January 2020. The decision for continuation or cessation of antithrombotic agents was based on the Guidelines for Gastroenterological Endoscopy in Patients Undergoing Antithrombotic Treatment.Results: Oral antithrombotic agents were administered to 28 patients (22.8%). The en bloc R0 resection rate was 98.4%. The MSCC method and the PMSCC method for preventing DB were performed in 114 and 9 lesions, respectively. The median resection time of the MSCC method was 16 min, and the median speed (the resection area divided by the resection time) was 3.6 cm2/10 min. The median resection time of the PMSCC method was 59 min, and the median speed was 1.3 cm2/10 min. The only delayed procedural adverse event was DB in 1 (0.8%) of the 123 lesions.Conclusions: The ABI strategy is feasible for preventing DB both in patients at low risk and in those at high risk for DB after GESD, whereas the PMSCC method may be necessary for reduction of time.

Abstract
Background: In the past decade, the brown marmorated stink bug (BMSB), Halyomorpha halys (Hemiptera: Pentatomidae) has caused extensive damage to global agriculture. As a high-risk pest for many countries, including New Zealand, it is important to explore its genetic diversity to enhance our knowledge on and devise management strategies for BMSB populations. In this study, two mitochondrial genes, Cytochrome c oxidase I (COI) and Cytochrome c oxidase II (COII) were used to explore the genetic diversity among 463 BMSB individuals collected from 12 countries.Result: In total, 51 COI and 29 COII haplotypes of BMSB were found, which formed 59 combined haplotypes (5 reported and 54 novel). Of these, H1h1 was the predominant haplotype. The haplotype diversity (Hd) and nucleotide diversity (π) were high while the neutrality (Fu's Fs) values were negative for the BMSB populations in the native countries, China, and Japan. For the BMSB populations from the invaded countries, the Fu's Fs values were negative for populations from Chile, Georgia, Hungary, Italy, Romania, Turkey, and USA, indicating that those populations are under demographic expansion. In comparison, the Fu's Fs values were positive for the populations from Austria, Serbia, and Slovenia, revealing a potential population bottleneck. Analysis of molecular variance (AMOVA) suggested that significant genetic difference exist between groups of populations: China, Japan, and the invasive populations.Conclusion: This study revealed that the haplotype diversity of the BMSB populations was high in those two studied countries where BMSB is native to (China and Japan) but low in those countries which have been invaded by the species. The analysis indicated that multiple invasions of BMSB occurred and a new stable genetic cluster has established in Europe and the USA. The study also revealed that three ancestral lines and most of the novel haplotypes were evolved from them. Moreover, we observed two genetic clusters in the invasive populations that are formed during different invasion events. Our study provided a comprehensive overview on the global haplotypes distribution thus expanding the existing knowledge on BMSB genetic diversity that potentially could play an important role in formulating feasible pest management strategies, especially biocontrol.
