Aim: The purpose of the study is the development and evaluation of the informativeness of the author’s 3D nephrometric score application to predict the probability of intraoperative and postoperative complications in kidney operations. Material and methods: The study includes 264 patients who underwent surgical treatment of renal tumors, before that CT and 3D modeling were carried out. All patients underwent an analysis of the surgical intervention complexity on the C-index, PADUA, R.E.N.A.L., and developed 3D nephrometric score. To determine the set of variables that allow to classify patients, the method of discriminant analysis was used to predict the nature, volume of blood loss, duration of ischemia, and the number of complications. The sensitivity and specificity of the predictors were estimated with the help of ROC analysis. Results: Indicators have been established to classify patients according to the probability of complications, the amount of blood loss and the duration of ischemia during surgery for kidney cancer. We have created linear models that predict the development of bleeding during surgery, the volume of blood loss of more than 200 ml and the duration of ischemia more than 20 min, as well as the likelihood of complications using discriminant functions. The proposed author’s nephrometric score exceeds the capabilities of C-index, PADUA, R.E.N.A.L in many ways in blood loss and time of ischemia predicting, which allows us to recommend it for the assessment of resectability in kidney operations.
Knowledge and Beliefs Regarding Harm From Specific Tobacco Products: Findings From the H.I.N.T. Survey
Authors: Lin Wenxue , Muscat Joshua E. 
Published: August 2021

Purpose: Determine whether dual tobacco users have different levels of knowledge about nicotine addiction, perceived harm beliefs of low nicotine cigarettes (LNCs) and beliefs about electronic cigarettes (e-cigarettes) Design: Quantitative, Cross-sectional Setting: Health Information National Trends Survey 5 (Cycle 3, 2019) Participants: Nationally representative adult non-smokers (n=3113), exclusive cigarette smokers (n=302), and dual (cigarette and e-cigarette) users (n=77). Measures: The survey included single item measures on whether nicotine causes addiction and whether nicotine causes cancer. A five-point Likert scale assessed comparative harm of e-cigarettes and LNCs relative to conventional combustible cigarettes (1=much more harmful, 3=equally harmful…5 = much less harmful, or don’t know). Analysis: We used weighted multiple linear regression model to estimate means and 95% confidence intervals (CI) of e-cigarettes and LNCs beliefs by current tobacco user status. Results: Over 97% of dual users, 83% of non-smokers and 86% of exclusive cigarette smokers correctly identified that nicotine is addictive. The majority of subjects incorrectly identified nicotine as a cause of cancer, with dual users having the lowest proportion of incorrect responses (60%). Dual users rated e-cigarette harmfulness as less harmful than combustibles (mean=2.20; 95% CI=1.73, 2.66) while exclusive cigarette smokers and non-smokers rated them as similarly harmful. LNCs were considered equally harmful and addictive as conventional cigarettes. Conclusion: Dual users had a higher knowledge base of tobacco-related health effects. The effectiveness of policies or medical recommendations to encourage smokers to switch from cigarettes to LNCs or e-cigarettes will need to consider accurate and inaccurate misperceptions about the harm and addictiveness of nicotine. Improved public health messages about different tobacco products are needed.
Advances in vascular anatomy and pathophysiology using high resolution and multiparametric sonography
Authors: Ilaria Petrucci , Mario Meola , Ilaria Fiorina 
Published: August 2021

B-mode and Color Doppler are the first-line imaging modalities in cardiovascular diseases. However, conventional ultrasound (US) provides a lower spatial and temporal resolution (70–100 frames per second) compared to ultrafast technology which acquires several thousand frames per second. Consequently, the multiparametric ultrafast platforms manage new imaging algorithms as high-frequency ultrasound, contrast-enhanced ultrasound, shear wave elastography, vector flow, and local pulse wave imaging. These advances allow better ultrasound performances, more detailed blood flow visualization and vessel walls’ characterization, and many future applications for vascular viscoelastic properties evaluation. In this paper, we provide an overview of each new technique’s principles and concepts and the real or potential applications of these modalities on the study of the artery and venous anatomy and pathophysiology of the upper limb before and after creating a native or prosthetic arterio-venous fistula. In particular, we focus on high-frequency ultrasound that could predict cannulation readiness and its potential role in the venous valvular status evaluation before vascular access creation; on contrast-enhanced ultrasound that could improve the peri-operative imaging evaluation during US-guided angioplasty; on shear wave elastography and local pulse wave imaging that could evaluate preoperative vessels stiffness and their potential predictive role in vascular access failure; on vector flow imaging that could better characterize the different components of the vascular access complex flow.

Published: August 2021

Background: Radial arterial catheters (RAC) are commonly used in emergency services and intensive care units (ICU) for continuous invasive monitoring of blood pressure and arterial blood gas sampling. Complications associated with RAC are rare. Regarding length of RAC catheters and complications, few studies were found in the literature. The present study seeks to provide health care professionals with scientific evidence to select an optimal length of RAC, based on the difference in the incidence of complications between ultrasound-guided catheters of the same diameter but different lengths. Methods: Observational, descriptive, retrospective study. Patients older than 17 years admitted to the emergency department or ICU were included. RAC were placed with diameters of 20 gauge, between 5 and 8 cm (Arrow–Teleflex), and 22 gauge diameters between 4 and 8 cm (Vygon). Univariate analysis was made to determine behavior of the numerical variables. Normality of variables was determined through a Shapiro-Wilk-test. Qualitative variables were expressed in percentages, quantitative variables in means and standard deviation, or with median and quartiles in the case of a non-normal distribution. Chi-square or Fisher method was used for qualitative variables and the t-test for symmetric quantitative variables. Asymmetric distributions were processed with the Mann-Whitney U test. A value p < 0.05 was considered statistically significant. The statistical analysis was performed with Stata 14.1 program. Results: About 793 RAC were placed between 2016 and 2019 were included, median age was 60 (37–73) (RIQ) years, 49% male. Complications were reported in all groups on average 17.5%, the most frequent being dysfunction/occlusion of the catheter. Given complications of the same diameter and different catheter lengths, there were no statistical differences between groups. Conclusion: Selecting one length or another with a catheter of the same diameter does not have statistically significant differences, in terms of the complications this device may cause—meaning that size does not matter.
Sharing-collaborative economy in tourism: A bibliometric analysis and perspectives for the post-pandemic era
Authors: Vila-Lopez Natalia , Küster-Boluda Inés 
Published: August 2021

Sharing economy research has risen exponentially during the last 4 years. Although several theoretical revisions on this topic have been developed, a conceptual analysis based on bibliometric techniques and science mapping tools is lacking. Within this framework, this article has two aims: (i) to carry on a performance analysis to identify the outstanding themes and (ii) to visually present the scientific structure by topics of research in sharing-collaborative economy as well as its evolution to identify future directions. The resources in the Web of Science Citation Index were used. Intelligent techniques and, more specifically, the SciMAT tool (based on co-word analysis and h-index analysis) were applied using a sample of 940 indexed papers from 2010 to 2020 (with 10.652 global citations). Our results show that the new post-pandemic era requires the sharing economy industry to investigate alternative ways: to improve trust, to innovate, to search for authenticity and experiences, to attend tourist motivations based on sustainability, and to use big data and manage overtourism.
Professionals’ attitudes towards people with intellectual disabilities who self-harm: A literature review
Authors: Samways Beverley 
Published: August 2021

Background: National Institute for Health and Care Excellence (NICE, 2013) Guidance on Self-Harm states that professionals supporting people who self-harm should demonstrate compassion, respect and dignity. This literature review examines the evidence for professionals’ attitudes towards people with intellectual disabilities who self-harm. Method: Four databases (PsychInfo, IBSS, CINAHL and Medline) were systematically searched to find relevant research since 2000. Results: Four studies met the criteria. Attitudes of professionals supporting people with intellectual disabilities are contrasted with those of professionals in settings focused on supporting people without intellectual disabilities. Professionals supporting people with intellectual disabilities tended to display attitudes and attributions reflective of biobehavioural and psychosocial theories of self-harm, with a greater emphasis on relationships. Conclusion: Much more research is needed which examines the attitudes of professionals supporting people with intellectual disabilities who self-harm.
Acutely increased workload is correlated with significant injuries among national basketball association players
Authors: Orringer Matthew J , Pandya Nirav K 
Published: August 2021

Background Particularly at the level of professional athletics, injury prevention is of critical importance. We hypothesized that elevated in-game statistics over a period of 3-10 games places increased cumulative stress on players’ joints and thus predisposes players to injury. Methods Utilizing a comprehensive database of National Basketball Association (NBA) player statistics, we identified 34 NBA players who suffered significant in-game injuries during the 2016-2019 seasons, leading them to miss at least ten consecutive games. We then assessed several potential markers of increased player workload during the cumulative one, three, five, and ten games directly preceding the injuries and compared them to season averages for each player. Results Increased minutes played per game over the cumulative three (4.9% increase, p = 0.04), five (5.8% increase, p = 0.004), and ten (4.0% increase, p = 0.02) games directly preceding injury were closely related to increased injury occurrence. In-game activity level as measured by statistics such as points scored and rebounds per game did not relate to injury occurrence. Conclusion In addition to injury mitigation practices currently used by NBA teams, maintaining players’ minutes played per game constant over time may be an additional effective strategy to be used by coaches and general managers in the future.
Input Quality Upgrading from Tariff Reduction and Firm Productivity: Evidence from Ethiopian Manufacturing
Authors: Gebreamilack Zenebech Admasu , Feng Yin 
Published: August 2021

Using a panel of firms from Ethiopian manufacturing census covering the period 2000–2016, this paper investigates how openness to trade help firms' input quality upgrading which further contribute to productivity gains. We estimate the quality of imported inputs at the firm level, and firm-level productivity using the Levinsohn and Petrin method. Then we estimate the effect of input tariff cut on input quality and further measure how input quality through input tariff reduction affect firms' productivity at different stages of regression. Our results suggest that input tariff reduction is associated with firms’ input quality upgrading and further with improvement in firms’ productivity.The effect of tariff cut is more pronounced for input-importing firms, and our result implies that the effect of input tariff cut motivates firms to participate in foreign input markets and helps upgrading input quality, thus contributing to firm productivity. Hence, further input trade liberalization measures should be designed to help key strategic manufacturing sectors. Besides, strategies have to be put in place to integrate the manufacturing sector into the global supply chain to reap more productivity gains. JEL Codes: D22 D24 F13 H32 L15 L23

Published: August 2021

Background Impaired active digital extension is common after stroke, hindering functional rehabilitation, and predicting poor recovery. The SaeboGlove assists digital extension and may improve outcome after stroke. We recently performed a single group, open, pilot trial of the SaeboGlove early after stroke which demonstrated satisfactory safety, feasibility and acceptability. An adequately powered randomised clinical trial is now needed to assess the clinical effectiveness of the SaeboGlove. Methods SUSHI is a pragmatic, multicentre, parallel-group, randomised controlled trial with blinded outcome assessment, and embedded process and economic evaluations. Adults, 7–60 days post-stroke, with upper limb disability and severe hand impairment, including reduced active digital extension, will be recruited from NHS inpatient stroke services in Scotland. Participants will be randomised on a 1:1 basis to receive 6 weeks of self-directed, repetitive, functional-based practice involving a SaeboGlove plus usual care, or usual care only. The primary outcome is upper limb function measured by the Action Research Arm Test (ARAT) at 6 weeks. Secondary outcomes will be measured at 6 and 14 weeks. A process evaluation will be performed via interviews with ‘intervention’ participants, and their carers and clinical therapists. A within-trial cost-effectiveness analysis will be performed. 110 participants are required to detect a difference between groups of 9 in the ARAT with 90% power at a 5% significance level allowing for 11% attrition. Discussion SUSHI will determine if SaeboGlove self-directed, repetitive, functional-based practice improves upper limb function after stroke, whether it is acceptable to stroke survivors and whether it is cost-effective.
RETRACTED ARTICLE: Haplotype analysis on correlation between transcription factor 7-like 2 gene polymorphism and breast cancer risk
Authors: Wang Yang , Men Xiaojuan , Gu Yongxue , Wang Huidong , Xu Zhicai 
Published: August 2021

Abstract
Background
Up to now, limited researches focused on the association between transcription factor 7-like 2 gene (TF7L2) gene single nucleotide polymorphisms (SNPs) and breast cancer (BC) risk. The aim of this study was to evaluate the associations between TF7L2 and BC risk in Chinese Han population.

Methods
Logistic regression model was used to test the correlation between polymorphisms and BC risk. Strength of association was evaluated by odds ratio (OR) and 95% confidence interval (CI). Generalized multifactor dimensionality reduction (GMDR) was applied to analyze the SNP-SNP and gene-environment interaction.

Results
Logistic regression analysis indicated that the BC risk was obviously higher in carriers of rs1225404 polymorphism C allele than that in TT genotype carriers (TC or CC versus TT), adjusted OR (95%CI) =1.40 (1.09–1.72). Additionally, we also discovered that people with rs7903146- T allele had an obviously higher risk of BC than people with CC allele (CT or TT versus CC), adjusted OR (95%CI) =1.44 (1.09–1.82). GMDR model was used to research the effect of interaction among 4 SNPs and environmental factors on BC risk. We discovered an important two-locus model (p = 0.0100) including rs1225404 and abdominal obesity, suggesting a potential gene–environment correlation between rs1225404 and abdominal obesity. In general, the cross-validation consistency of two-locus model was 10 of 10, and the testing accuracy was 0.632. Compared with subjects with normal waist circumference (WC) value and rs1225404 TT genotype, abdominal obese subjects with rs1225404 TC or CC genotype had the highest BC risk. After covariate adjustment, OR (95%CI) was 2.23 (1.62–2.89). Haplotype analysis indicated that haplotype containing rs1225404-T and rs7903146-C alleles were associated with higher BC risk.

Conclusions
C allele of rs1225404 and T allele of rs7903146, interaction between rs1225404 and abdominal obesity, rs1225404-T and rs7903146-C haplotype were all related to increased BC risk.

AbstractBackgroundPrevention of mother-to-child HIV transmission (PMTCT) services in Kenya can be strengthened through the delivery of relevant and culturally appropriate SMS messages.MethodsThis study reports on the results of focus groups conducted with pre and postnatal women living with HIV (5 groups,n = 40) and their male partners (3 groups,n = 33) to elicit feedback and develop messages to support HIV+ women’s adherence to ART medication, ANC appointments and a facility-based birth. The principles of message design informed message development.ResultsRespondents wanted ART adherence messages that were low in verbal immediacy (ambiguous), came from an anonymous source, and were customized in timing and frequency. Unlike other studies, low message immediacy was prioritized over customization of message content. For retention, participants preferred messages with high verbal immediacy—direct appointment reminders and references to the baby—sent infrequently from a clinical source.ConclusionOverall, participants favored content that was brief, cheerful, and emotionally appealing.

Published: August 2021

Abstract
Background
The aim of the present study was to evaluate the incidence of unsuspected PJI when prosthetic revisions are thoroughly evaluated by PJI dedicated orthopedic surgeon before surgery. The hypothesis is that the incidence of unsuspected PJI is reduced by applying this protocol.

Methods
This is a historical cohort study carried out in one university hospital. The prosthetic revision assessment was carried out in January 2019. From that date on, all patients that were programmed for hip or knee revision (either by an orthopedic surgeon specialized or not in septic revisions) were scheduled for a preoperative visit with the same orthopedic surgeon specialized in septic revisions. The diagnostic algorithm applied was based on the Pro-Implant Foundation diagnostic criteria. Prior to the revision assessment, the indication for joint aspiration was done at the surgeons’ discretion (non-specialized in septic revisions) and the preoperative identification of PJI was also done by a hip or knee surgeon (not specialized in septic surgery).

Results
Based on the PIF criteria, there were 15 infections among the revisions in group 1 and 18 PJI in group 2 (p > 0.05). The most interesting finding was that there were 7 patients with unsuspected positive cultures in group 1. That represents 11% of all revisions. No patient in group 2 was found with unsuspected positive cultures (p < 0.001).

Conclusion
A thorough PJI diagnostic algorithm should be implemented before prosthetic revision to avoid unsuspected positive cultures.
Results of an experimental study of subgingival cleaning effectiveness in the furcation area
Authors: Seidel Miriam , Borenius Hannah , Schorr Susanne , Christofzik David , Graetz Christian 
Published: August 2021

Abstract
Background
Sufficient biofilm removal in the furcation area (FA) is a major challenge in the clinical practice of supportive periodontal therapy. The aim of the present experimental study was to simulate subgingival cleaning of the FA using a powered scaler (sonic scaler (AIR), ultrasonic scaler (US)) for conventional mechanical debridement versus two air polishing with nonabrasive powder (LAPA-1: glycine powder, LAPA-2: erythritol powder) and different nozzles for supra-/subgingival cleaning for each device.

Methods
Seven trained and calibrated operators with ≥ 2 years each of professional experience in treating periodontitis used the instruments to clean 3D-printed replicas of six molars with through-and-through FA (four 3-rooted and two 2-rooted teeth) in a manikin head. AIR and US were used in the control group; air polishing instruments were used in the test group. For reproducible evaluation, the test teeth were separated vertically into two or three parts, illuminated with ultraviolet light, photographed and evaluated planimetrically. Treatment time (TrT, in s) and relative cleaning efficacy (RCE, in %) were measured.

Results
Overall, 3-rooted molars (RCE in the entire FA, 23.19 ± 20.98%) could be cleaned significantly less effectively than 2-rooted molars (53.04 ± 28.45%, p < 0.001), regardless of the instrument used. In the cleaning of the entire FA, significantly higher RCE values were achieved with conventional mechanical debridement (AIR/US: 46.04 ± 25.96%/39.63 ± 22.02%; AIR vs. US: p > 0.05) than with air polishing (LAPA-1/LAPA-2: 34.06 ± 29.48%/17.09 ± 18.85%; LAPA-1 vs. LAPA-2: p < 0.001) regardless of whether a supra- or subgingival cleaning nozzle used (p < 0.001). Only LAPA-1 with a subgingival nozzle showed RCE values comparable to those of US (41.07 ± 28.95% vs. 39.63 ± 22.02%, p > 0.05). TrT was longest for US (299.40 ± 120.69 s) and shortest for LAPA-1 with a supragingival nozzle (129.67 ± 60.92 s, p < 0.001).

Conclusions
All of the examined instruments were effective to some degree in removing the simulated biofilm from the FA, but they differed substantially in cleaning efficacy. Only one air polishing device (LAPA-1) with a rigid subgingival nozzle was able to achieve RCE values similar to those of US. The current investigation confirmed that conventional mechanical debridement with powered scalers were most effective, but treatment took longer with these devices than air polishing.
