Influence of Saudi Vision 2030 on housing-related macroeconomic variables
Authors: Hariri Mohammad 
Published: May 2022

Purpose
This study aims to explore the effect of Saudi Vision 2030 and its government initiatives on macroeconomic variables related to housing.

Design/methodology/approach
This exploratory study used an empirical–analytical approach. Based on secondary data, a set of hypotheses was contrasted to verify whether there has been any change in the trends of macroeconomic variables related to housing after Saudi Vision 2030 entered into force.

Findings
The results show that the trend of percentage of housing ownership went from a continuous decrease to accelerated growth since the implementation of Saudi Vision 2030. However, the effect of these advances is not observed in non-oil gross domestic product (GDP) or in the economic activities of the construction, real estate and financial services sectors.

Research limitations/implications
This study notes that despite successful housing outcomes, it appears that Saudi Vision 2030 does not have a positive impact on non-oil GDP. Consequently, government entities should review the degree to which other economic activities contribute to non-oil GDP. A limitation of the study was that the GDP of housing construction and marketing and that of granting mortgage loans were not specifically available, nor were data on public and private investment made for implementing government initiatives.

Originality/value
To the best of the authors’ knowledge, this is the first study to explore the effect of Saudi Vision 2030 on housing and its contribution to the economy.

ObjectiveTo determine whether proficiency‐based progression (PBP) training leads to better robotic surgical performance compared to traditional training (TT), given that the value of PBP training for learning robotic surgical skills is unclear.Materials and MethodsThe PROVESA trial is a multicentric, prospective, randomized and blinded clinical study comparing PBP training with TT for robotic suturing and knot‐tying anastomosis skills. A total of 36 robotic surgery‐naïve junior residents were recruited from 16 training sites and 12 residency training programmes. Participants were randomly allocated to metric‐based PBP training or the current standard of care TT, and compared at the end of training. The primary outcome was percentage of participants reaching the predefined proficiency benchmark. Secondary outcomes were the numbers of procedure steps and errors made.ResultsOf the group that received TT, 3/18 reached the proficiency benchmark versus 12/18 of the PBP group (i.e. the PBP group were ~10 times as likely to demonstrate proficiency [P = 0.006]). The PBP group demonstrated a 51% reduction in number of performance errors from baseline to the final assessment (18.3 vs 8.9). The TT group demonstrated a marginal improvement (15.94 vs 15.44) in errors made.ConclusionsThe PROVESA trial is the first prospective randomized controlled trial on basic skills training in robotic surgery. Implementation of a PBP training methodology resulted in superior surgical performance for robotic suturing and knot‐tying anastomosis performance. Compared to TT, better surgical quality could be obtained by implementing PBP training for basic skills in robotic surgery.
Nasopharyngeal cancer cell‐derived exosomal PD‐L1 inhibits CD8+ T‐cell activity and promotes immune escape
Authors: Yang Jie , Chen Jierong , Liang Hu , Yu Yahui 
Published: May 2022

AbstractProgrammed cell death ligand 1 (PD‐L1) is an immune surface protein that binds to programmed cell death 1 (PD‐1) and allows tumors to evade T‐cell immunity. This study aims to define the role of PD‐L1 shuttled by tumor cell‐derived exosomes in the immune escape of nasopharyngeal carcinoma (NPC). PD‐L1 expression was determined in the exosomes isolated from the plasma of NPC patients or from NPC cells. It was found that PD‐L1 was highly expressed in the exosomes from the plasma of NPC patients and also in the exosomes from NPC cells. PD‐L1/PD‐1 binding was identified in the presence or absence of interferon‐gamma (IFN‐γ) or anti‐PD‐L1 antibody. PD‐L1 expression was elevated following IFN‐γ treatment. Binding of PD‐L1 to PD‐1 was augmented by IFN‐γ and blocked by anti‐PD‐L1 antibody. Following this, CD8+ T cells were sorted out from peripheral blood samples to assess the binding between exosomal PD‐L1 and PD‐1 on the CD8+ T‐cell surface, and to measure the percentage of Ki‐67‐positive T cells. The results indicated that exosomal PD‐L1 bound to the PD‐1 on CD8+ T‐cell surface, leading to a reduced percentage of Ki‐67‐positive CD8+ T cells and downregulated production of cytokines. In vivo data confirmed that exosomal PD‐L1 promoted NPC tumor growth in mice by suppressing CD8+ T‐cell activity. In conclusion, NPC cell‐derived exosomes deliver PD‐L1 to bind to PD‐1 on the CD8+ T‐cell surface, through which cytotoxic CD8+ T‐cell function was attenuated and the immune escape was thus promoted in NPC.

Published: May 2022

AbstractDigital terrains are a foundational element in the computer‐generated depiction of natural scenes. Given the variety and complexity of real‐world landforms, there is a need for authoring solutions that achieve perceptually realistic outcomes without sacrificing artistic control. In this paper, we propose setting aside the elevation domain in favour of modelling in the gradient domain. Such a slope‐based representation is height independent and allows a seamless blending of disparate landforms from procedural, simulation, and real‐world sources. For output, an elevation model can always be recovered using Poisson reconstruction, which can include Dirichlet conditions to constrain the elevation of points and curves.In terms of authoring our approach has numerous benefits. It provides artists with a complete toolbox, including: cut‐and‐paste operations that support warping as needed to fit the destination terrain, brushes to modify region characteristics, and sketching to provide point and curve constraints on both elevation and gradient. It is also a unifying representation that enables the inclusion of tools from the spectrum of existing procedural and simulation methods, such as painting localised high‐frequency noise or hydraulic erosion, without breaking the formalism. Finally, our constrained reconstruction is GPU optimized and executes in real‐time, which promotes productive cycles of iterative authoring.
Volumetric Multi‐View Rendering

Published: May 2022

AbstractRendering photo‐realistic images using Monte Carlo path tracing often requires sampling a large number of paths to reach acceptable levels of noise. This is particularly the case when rendering participating media, that complexify light paths with multiple scattering events. Our goal is to accelerate the rendering of heterogeneous participating media by exploiting redundancy across views, for instance when rendering animated camera paths, motion blur in consecutive frames or multi‐view images such as lenticular or light‐field images. This poses a challenge as existing methods for sharing light paths across views cannot handle heterogeneous participating media and classical estimators are not optimal in this context. We address these issues by proposing three key ideas. First, we propose new volume shift mappings to transform light paths from one view to another within the recently introduced null‐scattering framework, taking into account changes in density along the transformed path. Second, we generate a shared path suffix that best contributes to a subset of views, thus effectively reducing variance. Third, we introduce the multiple weighted importance sampling estimator that benefits from multiple importance sampling for combining sampling strategies, and from weighted importance sampling for reducing the variance due to non contributing strategies. We observed significant reuse when views largely overlap, with no visible bias and reduced variance compared to regular path tracing at equal time. Our method further readily integrates into existing volumetric path tracing pipelines.

AbstractSpectral geometric methods have brought revolutionary changes to the field of geometry processing. Of particular interest is the study of the Laplacian spectrum as a compact, isometry and permutation‐invariant representation of a shape. Some recent works show how the intrinsic geometry of a full shape can be recovered from its spectrum, but there are approaches that consider the more challenging problem of recovering the geometry from the spectral information of partial shapes. In this paper, we propose a possible way to fill this gap. We introduce a learning‐based method to estimate the Laplacian spectrum of the union of partial non‐rigid 3D shapes, without actually computing the 3D geometry of the union or any correspondence between those partial shapes. We do so by operating purely in the spectral domain and by defining the union operation between short sequences of eigenvalues. We show that the approximated union spectrum can be used as‐is to reconstruct the complete geometry [MRC*19], perform region localization on a template [RTO*19] and retrieve shapes from a database, generalizing ShapeDNA [RWP06] to work with partialities. Working with eigenvalues allows us to deal with unknown correspondence, different sampling, and different discretizations (point clouds and meshes alike), making this operation especially robust and general. Our approach is data‐driven and can generalize to isometric and non‐isometric deformations of the surface, as long as these stay within the same semantic class (e.g., human bodies or horses), as well as to partiality artifacts not seen at training time.

AbstractIntroductionTo evaluate the initial use of label‐free second harmonic generation (SHG) imaging with two‐photon excitation (2PE) auto‐fluorescence in multiphoton microscopy (MPM) for the quantification of collagen/fibrosis on preimplantation biopsies of extended criteria donors (ECD).Materials and methodsTwenty preimplantation core biopsies were extracted from 10 donor kidney samples, of which originated from seven donors. Kidney Donor Profile Index (KDPI) and Remuzzi scores of biopsies were calculated. Collagen parameters measured included quantification by the Collagen Area Ratio in Total Tissue (CART) and qualitative measurements by Collagen Reticulation Index (CRI).ResultsBiopsies classified with > 85% KDPI scores had significantly higher CART (p = .011) and lower CRI values (p = .025) than biopsies with ≤ 85% KDPI scores. Increase in CRI values correlated significantly with rise in recipient creatinine levels 1‐year post‐transplant (p = .027; 95% CI: 4.635‐66.797).ConclusionMPM is an evolving technology that enables the quantification of the amount (CART) and quality (CRI) of collagen deposition in unstained preimplantation biopsies of donor kidneys stratified by KDPI scores. This initial evaluation found significant differences in both parameters between donor kidneys with more or less than 85% KDPI.

Published: May 2022

AbstractAim(i) To assess the dependence between the form of the decrease in biological similarity with distance (distance‐decay) and species range size and (ii) to introduce the use of a sigmoidal model, the Gompertz function, as a flexible alternative able to fit distance‐decay models under a wide variety of species range sizes.LocationApplicable worldwide.MethodsWe computed distance‐decay curves from simulated communities to assess how the species range sizes shape the functional form of distance‐decay patterns (i.e. negative exponential, power‐law or sigmoidal [Gompertz] relationships). Simulations were performed using different sample sizes and species detection probabilities. We also used distribution data of South American mammals to explore the relationship between species range size and the distance‐decay form in an empirical dataset.ResultsOur simulations showed that the power‐law is the best supported model when range sizes tend to be small. An increase in range sizes leads to a negative exponential relationship, taking the shape of a sigmoidal (Gompertz) relationship with the largest range size values. Similar results have been found in the distance‐decay pattern of South American mammals. Remarkably, the Gompertz function fits the data reasonably well in all scenarios.Main conclusionsThe functional form of distance‐decay patterns depends on a key biogeographical attribute: species range size. This dependence makes it an interesting tool to detect biodiversity threats associated with species range expansion, such as the biotic homogenization of faunas. The Gompertz function is the mathematical model that best accommodates different frequency distributions of species range size and, thus, allows cross‐taxa comparison of this biogeographical and ecological pattern.
Role of the endoscopic Doppler probe in nonvariceal upper gastrointestinal bleeding: Systematic review and meta‐analysis

Published: May 2022

ObjectivesThe effectiveness of the Doppler endoscopic probe (DEP) remains unclear in nonvariceal upper gastrointestinal bleeding (NVUGIB). We thus performed a systematic review characterizing the effectiveness of DEP in patients with NVUGIB addressing this question.MethodsA literature search was done until July 2021 using MEDLINE, EMBASE, and ISI Web of Science. A series of meta‐analyses were performed assessing outcomes among observational and interventional studies for DEP signal positive and negative lesions as well as DEP‐assisted versus standard endoscopies. The primary outcome was “overall rebleeding”; secondary outcomes included all‐cause mortality, bleeding‐related mortality, need for surgery, length of stay, intensive care unit stay, and angiography.ResultsFourteen studies were included from 1911 citations identified. Observational studies compared bleeding lesions with DEP‐positive versus DEP‐negative signals (11 studies, n = 800 prehemostasis; five studies, n = 148 with posthemostasis data). Three interventional studies (n = 308) compared DEP‐assisted to standard endoscopy management. DEP signal positive versus negative lesions either prior to or following any possible hemostasis were at greater risk of overall rebleeding (odds ratio [OR] 6.54 [2.36, 18.11] and OR 25.96 [6.74, 100.0], respectively). The use of DEP during upper endoscopy significantly reduced overall rebleeding rates (OR 0.27 [0.14, 0.54]). When removing outcomes analysis for which only one study was available, all evaluable outcomes were improved with DEP characterization of management guidance except for all‐cause mortality.ConclusionAlthough with low certainty evidence, DEP‐related information improves on sole visual prediction of rebleeding in NVUGIB, with DEP‐guided management yielding decreased overall rebleeding, bleeding‐related mortality, and need for surgery.
‘Low‐normal’ motor skills in infants at high risk for poor developmental outcomes: A prevalence and prognostic study

Published: May 2022

AbstractAimTo investigate the prevalence and prognostic value of ‘low‐normal’ motor skills in infants at high‐risk for poor developmental outcomes.MethodInfants born extremely low‐birthweight and extremely preterm discharged from neonatal intensive care between 2015 and 2018 completed the Alberta Infant Motor Scale (AIMS), Neuro‐Sensory Motor Developmental Assessment (NSMDA) at corrected age 4, 8, and 12 months, and Griffiths Mental Development Scale at corrected age 12 months.ResultsParticipating infants (n = 191) with a mean gestational age (95% confidence interval [CI]) of 26.80 weeks (26.60, 27.1) and mean birthweight (95% CI) of 869 grams (843, 895) included 45 (23.80%) infants small for gestational age. AIMS rated 50.32%, 35.37%, and 14.86% of infants within the ‘low‐normal’ motor skills range (1–2 SD below the mean for age) at 4, 8, and 12 months respectively. Of the infants within the AIMS ‘low‐normal’ skills range, 55.70%, 88.46%, and 59.10% were classified as having impairment by NSMDA at 4, 8, and 12 months respectively. Griffiths assessment at 12 months identified only 7.33% of infants with ‘low‐normal’ skills and 3.33% with motor disability. Minimal motor impairment rating on the NSMDA at 4 or 8 months significantly predicted general development at 12 months.InterpretationHigh‐risk infants with ‘low‐normal’ motor skills may warrant referral to early intervention as associated impairment represents increased risk for poorer general development outcomes.What this paper adds

High prevalence of ‘low‐normal’ motor skill exists in high‐risk infants.

Clinical motor assessment validly identifies infants with motor impairment.

Minimal motor impairment in high‐risk infants is prognostic of general development.

High‐risk infants with ‘low‐normal’ motor skills may warrant early intervention.

Griffiths Scales of Child Development, Third Edition assessment at 12‐months age may under‐identify motor difficulties.

AbstractBackgroundThe dualistic diagnostic criteria for metabolic syndrome overlooked the severity of metabolic syndrome, and the relationships between the severity of metabolic syndrome and adverse health conditions are poorly characterized. We therefore aimed to investigate the associations of metabolic syndrome severity with incident cardiovascular disease (CVD)/all‐cause mortality.MethodsA total of 116,772 participants from the Kailuan study were followed up biennially between 2006 and 2018. The severity of metabolic syndrome was evaluated using a continuous metabolic syndrome severity score (MetS score). Cox proportional hazards model was used to examine the association between MetS score and the risk of CVD and all‐cause mortality. Restricted cubic spline analyses were performed to explore the dose–response associations.ResultsWe found that the risk of CVD and all‐cause mortality increased consistently with the MetS score. In the multivariable‐adjusted model, the hazard ratios of CVD and all‐cause mortality were 2.05 (95% CI 1.86–2.25) and 1.45 (95% CI 1.35–1.56), respectively, in those subjects>75th percentile compared with those <25th percentile. Additionally, a J‐shaped dose–response relationship was found between MetS score and the risk of all‐cause mortality (pnonlinearity <.001), while a linear relationship between MetS score and the risk of CVD was observed in this study (pnonlinearity = .737).ConclusionsThis study suggests significant dose–response relationships between MetS score and the risk of CVD/mortality. Subjects without metabolic syndrome but with a relatively high MetS score should raise their awareness and pay more attention to the possible increased risk of CVD events.
