AbstractBackgroundCT scan images provide accurate anatomical data from different areas of the body that can be used to diagnose diseases.ObjectivesThe present work aimed to describe the normal anatomical structures of the Ile de France sheep head and its morphometric and volumetric properties using computed tomography (CT) and stereological methods.MethodsFive adult Ile de France sheep heads, which were of mature age (above 10 months), were included in this study. The different cavities of the head, including the nasal cavity, paranasal sinuses, oral cavity, orbital cavity and vestibulocochlear system, were evaluated using CT scans, cross, sagittal and coronal sections.ResultsThe mean length, height and width of the skull were 25.3 ± 1.02, 9.8 ± 0.93 and 12.3 ± 0.91 cm, respectively. The results showed that the nasal cavity is divided into three regions. Vestibular, respiratory and olfactory regions. The paranasal sinuses are composed of maxillary, frontal, palatine, sphenoid, lacrimal and ethmoidal that were identified and named in the CT scan images and their corresponding anatomical cross‐sections. The total volume of the head, nasal cavity and oral cavity was estimated to be 2998 ± 202.00, 303 ± 31.33 and 229.3 ± 10.61 cm3, respectively.ConclusionsThe frontal sinus in the Ile de France sheep was limited to the frontal bone without extending into the parietal, temporal, or occipital bones, similar to Saanen goat. This study provided a comprehensive atlas of Ile de France sheep anatomy to internal medicine veterinarians and surgeons.

Abstract
Purpose
Nonsurgical management has been identified as the treatment of choice for femoral shaft fractures in children below four years of age. For various reasons, the surgical approach has become increasingly popular in recent years. The aim of this study is to report results after vertical skin traction and analyze the benefits of this technique as well as to point out advantages compared with surgery in this age group.

Methods
The authors performed a retrospective data analysis, including all patients with femoral shaft fractures below the age of four who were treated with vertical skin traction at our institution between January 2006 and December 2016.

Results
Skin traction for a femoral shaft fracture was performed for 36 patients (mean age 1.6 years; 1 day–3.5 years). The mean duration of traction was 18.5 days (14–30). Complications included soft tissue affections (n = 5), which all healed spontaneously. Consolidation was observed in all fractures. Initial axial deviations and shortening did not change during traction until consolidation (p > 0.05), and no relevant torsion deformity occurred (p = 0.01). Patients gained full weight-bearing within 12.3 days (7–40) following end of traction. At the final follow-up, after a mean of 29.3 months (12–192), leg-length discrepancy (mean 7.1 mm; 5–20) was found on radiograms in nine cases, and axial deviations (mean 7.7°; 5–25) were documented in seven cases. None of the patients had limitations in daily activities or sports.

Conclusion
Skin traction is a technically easy, safe, and non-invasive treatment modality for femoral shaft fractures in children below the age of four years. Strong results are obtained benefited from a high potential of growth-related correction, and in principle no anesthesia is needed. A prolonged hospitalization and socio-economic factors maintain the ongoing debate in comparison with the surgical approach.

Abstract
Objectives
Neurodegeneration in suspected Alzheimer’s disease can be determined using visual rating or quantitative volumetric assessments. We examined the feasibility of volumetric measurements of gray matter (GMV) and hippocampal volume (HCV) and compared their diagnostic performance with visual rating scales in academic and non-academic memory clinics.

Materials and methods
We included 231 patients attending local memory clinics (LMC) in the Netherlands and 501 of the academic Amsterdam Dementia Cohort (ADC). MRI scans were acquired using local protocols, including a T1-weighted sequence. Quantification of GMV and HCV was performed using FSL and FreeSurfer. Medial temporal atrophy and global atrophy were assessed with visual rating scales. ROC curves were derived to determine which measure discriminated best between cognitively normal (CN), mild cognitive impairment (MCI), and Alzheimer’s dementia (AD).

Results
Patients attending LMC (age 70.9 ± 8.9 years; 47% females; 19% CN; 34% MCI; 47% AD) were older, had more cerebrovascular pathology, and had lower GMV and HCV compared to those of the ADC (age 64.9 ± 8.2 years; 42% females; 35% CN, 43% MCI, 22% AD). While visual ratings were feasible in > 95% of scans in both cohorts, quantification was achieved in 94–98% of ADC, but only 68–85% of LMC scans, depending on the software. Visual ratings and volumetric outcomes performed similarly in discriminating CN vs AD in both cohorts.

Conclusion
In clinical settings, quantification of GM and hippocampal atrophy currently fails in up to one-third of scans, probably due to lack of standardized acquisition protocols. Diagnostic accuracy is similar for volumetric measures and visual rating scales, making the latter suited for clinical practice.

Summary statement
In a real-life clinical setting, volumetric assessment of MRI scans in dementia patients may require acquisition protocol optimization and does not outperform visual rating scales.

Key Points
• In a real-life clinical setting, the diagnostic performance of visual rating scales is similar to that of automatic volumetric quantification and may be sufficient to distinguish Alzheimer’s disease groups.
• Volumetric assessment of gray matter and hippocampal volumes from MRI scans of patients attending non-academic memory clinics fails in up to 32% of cases.
• Clinical MR acquisition protocols should be optimized to improve the output of quantitative software for segmentation of Alzheimer’s disease–specific outcomes.

Abstract
Objectives
Prognoses for nasopharyngeal carcinoma (NPC) between categories T2 and T3 in the Eighth American Joint Committee on Cancer (AJCC) staging system were overlapped. We explored the value of skull base invasion (SBI) subclassification in prognostic stratification and use of induction chemotherapy (IC) to optimize T2/T3 categorization for NPC patients.

Methods
We retrospectively reviewed 1752 NPC patients from two hospitals. Eight skull base bone structures were evaluated. Survival differences were compared between slight SBI (T3 patients with pterygoid process and/or base of the sphenoid bone invasion only) and severe SBI (T3 patients with other SBIs) with or without IC using random matched-pair analysis. We calculated the prognosis and Harrel concordance index (C-index) for the revised T category and compared IC outcomes for the revised tumor stages.

Results
Compared to severe SBI, slight SBI showed better 5-year overall survival (OS) (81.5% vs. 92.3%, p = 0.001) and progression-free survival (PFS) (71.5% vs. 83.0%, p = 0.002). Additional IC therapy did not significantly improve OS and PFS in slight SBI. The proposed T category separated OS, PFS, and locoregional recurrence-free survival in T2 and T3 categories with statistical significance. An improved C-index for OS prediction was observed in the proposed T category with combined confounding factors, compared to the AJCC T staging system (0.725 vs. 0.713, p = 0.046). The survival benefits of IC were more obvious in the advanced stage.

Conclusions
NPC patients with slight SBI were recommended to downstage to T2 category. The adjustment for T category enabled better prognostic stratification and guidance for IC use.

Key Points
• For nasopharyngeal carcinoma (NPC) patients in T3 category, slight skull base invasion was a significant positive predictor for OS and PFS.
• NPC patients with slight SBI might not gain significant survival benefits from induction chemotherapy.
• Downstaging slight SBI NPC patients to T2 category would make a more accurate risk stratification, improve the predicting performance in OS, and have a better guidance in the use of IC for patients in advanced stage.

Abstract
Purpose
While the prevalence of obesity in inflammatory bowel disease (IBD) patients is rapidly increasing, it is unclear whether obesity affects surgical outcomes in this population. This meta-analysis aims to assess the impact of obesity/overweight on patients undergoing surgery for IBD.

Methods
Databases (PubMed, Web of Science, Cochrane Library, and Springer) were searched through September 2021. The meta-analysis included patients with surgically treated IBD to investigate the impact of obesity/overweight on this population. Primary outcomes included overall complications, infectious complications, noninfectious complications, and conversion to laparotomy.

Results
Fifteen studies totaling 12,622 IBD patients were enrolled. Compared with nonobese (including overweight) patients, obese IBD patients have increased the risk in terms of overall complications (OR = 1.45, p < 0.001), infectious complications (OR = 1.48, p = 0.003) (especially wound complications), as well as conversion to laparotomy (OR = 1.90, p < 0.001). Among the noninfectious complications, only the incidence of visceral injury (OR = 2.36, p = 0.05) had significantly increased. Compared with non-overweight patients, the risk of developing wound complications (OR = 1.65, p = 0.01) and sepsis (OR = 1.73, p = 0.007) were increased in overweight patients, but the rates of overall complications (OR = 1.04, p = 0.81), infectious complications (OR = 1.31, p = 0.07), and conversion to laparotomy (OR = 1.33, p = 0.08) associated with body mass index (BMI) were not significantly different.

Conclusion
Obesity is a risk factor for surgical complications in IBD patients, mainly reflected in infectious complications. Moreover, obese patients seem to have a more common chance of developing surgical complications than overweight patients.

Abstract
Purpose
The purpose of this study was to determine the significance of hinge position through comparison between open-wedge and closed-wedge high tibial osteotomy (HTO) and to determine the ideal hinge position to minimize the effect of HTO on the posterior tibial slope (PTS) and medial proximal tibial angle (MPTA).

Methods
Procedures were performed on 32 cadaveric knees using open-wedge HTO with the standard hinge position or a low hinge position or closed-wedge HTO with the standard hinge position or a low hinge position. To define the standard hinge position in open wedge HTO, we drew a line 3-cm inferior to the medial tibial plateau toward the fibular head and located the intersection of this line with a longitudinal line 1-cm medial to fibular shaft. The low hinge position was then defined as the point 1-cm inferior to the standard position. For the standard hinge position for closed-wedge HTO, we drew a line parallel with joint line from 2-cm inferior to the lateral tibial plateau. The low hinge position was then defined as the point 1-cm inferior to the standard position.

Results
For the open-wedge procedure, osteotomy through the low hinge position resulted in a significantly greater PTS compared to osteotomy through the standard hinge position. MPTA was also significantly greater for the low hinge position compared to standard hinge position. In the closed-wedge HTO, neither the PTS nor MPTA was significantly different for the low and standard hinge positions.

Conclusions
Hinge position significantly affects changes in the PTS and MPTA following open-wedge but not closed-wedge HTO. Understanding how to hinge position affects the PTS and MPTA is critical for surgeons performing open-wedge HTO procedures. Adopting an accurate hinge position is crucial for preventing complications, especially in open-wedge osteotomy, due to postoperative changes in the PTS and MPTA.

AbstractInvasive alien species (IAS) rank among the most significant drivers of species extinction and ecosystem degradation resulting in significant impacts on socio-economic development. The recent exponential spread of IAS in most of Africa is attributed to poor border biosecurity due to porous borders that have failed to prevent initial introductions. In addition, countries lack adequate information about potential invasions and have limited capacity to reduce the risk of invasions. Horizon scanning is an approach that prioritises the risks of potential IAS through rapid assessments. A group of 28 subject matter experts used an adapted methodology to assess 1700 potential IAS on a 5-point scale for the likelihood of entry and establishment, potential socio-economic impact, and impact on biodiversity. The individual scores were combined to rank the species according to their overall potential risk for the country. Confidence in individual and overall scores was recorded on a 3-point scale. This resulted in a priority list of 120 potential IAS (70 arthropods, 9 nematodes, 15 bacteria, 19 fungi/chromist, 1 viroid, and 6 viruses). Options for risk mitigation such as full pest risk analysis and detection surveys were suggested for prioritised species while species for which no immediate action was suggested, were added to the plant health risk register and a recommendation was made to regularly monitor the change in risk. By prioritising risks, horizon scanning guides resource allocation to interventions that are most likely to reduce risk and is very useful to National Plant Protection Organisations and other relevant stakeholders.
Epistemic Injustice in Incident Investigations: A Qualitative Study
Authors: Kok Josje , de Kam David , Leistikow Ian , Grit Kor , Bal Roland 
Published: May 2022

AbstractSerious incident investigations—often conducted by means of Root Cause Analysis methodologies—are increasingly seen as platforms to learn from multiple perspectives and experiences: professionals, patients and their families alike. Underlying this principle of inclusiveness is the idea that healthcare staff and service users hold unique and valuable knowledge that can inform learning, as well as the notion that learning is a social process that involves people actively reflecting on shared knowledge. Despite initiatives to facilitate inclusiveness, research shows that embracing and learning from diverse perspectives is difficult. Using the concept of ‘epistemic injustice’, pointing at practices of someone’s knowledge being unjustly disqualified or devalued, we analyze the way incident investigations are organized and executed with the aim to understand why it is difficult to embrace and learn from the multiple perspectives voiced in incident investigations. We draw from 73 semi-structured interviews with healthcare leaders, managers, healthcare professionals, incident investigators and inspectors, document analyses and ethnographic observations. Our analysis identified several structures in the incident investigation process, that can promote or hinder an actor’s epistemic contribution in the process of incident investigations. Rather than repeat calls to ‘involve more’ and ‘listen better’, we encourage policy makers to be mindful of and address the structures that can cause epistemic injustice. This can improve the outcome of incident investigations and can help to do justice to the lived experiences of the involved actors in the aftermath of a serious incident.

Abstract
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) causes the cytokine release syndrome (CRS) and leads to multiorgan dysfunction. Mitochondrial dynamics are fundamental to protect against environmental insults, but they are highly susceptible to viral infections. Defective mitochondria are potential sources of reactive oxygen species (ROS). Infection with SARS-CoV-2 damages mitochondria, alters autophagy, reduces nitric oxide (NO), and increases both nicotinamide adenine dinucleotide phosphate oxidases (NOX) and ROS. Patients with coronavirus disease 2019 (COVID-19) exhibited activated toll-like receptors (TLRs) and the Nucleotide-binding and oligomerization domain (NOD-), leucine-rich repeat (LRR-), pyrin domain-containing protein 3 (NLRP3) inflammasome. The activation of TLRs and NLRP3 by SARS‐CoV‐2 induces interleukin 6 (IL-6), IL-1β, IL-18, and lactate dehydrogenase (LDH). Herein, we outline the inflammatory circuit of COVID-19 and what occurs behind the scene, the interplay of NOX/ROS and their role in hypoxia and thrombosis, and the important role of ROS scavengers to reduce COVID-19-related inflammation.
Diapocynin neuroprotective effects in 3-nitropropionic acid Huntington’s disease model in rats: emphasis on Sirt1/Nrf2 signaling pathway

Published: May 2022

AbstractBackground and AimHuntington's disease (HD) is a rare inherited disease portrayed with marked cognitive and motor decline owing to extensive neurodegeneration. NADPH oxidase is considered as an important contributor to the oxidative injury in several neurodegenerative disorders including HD. Thus, the present study explored the possible neuroprotective effects of diapocynin, a specific NADPH oxidase inhibitor, against 3-nitropropionic acid (3-NP) model of HD in rats.MethodsAnimals received diapocynin (10 mg/kg/day, p.o), 30 min before 3-NP (10 mg/kg/day, i.p) over a period of 14 days.ResultsDiapocynin administration attenuated 3-NP-induced oxidative stress with significant increase in reduced glutathione, glutathione-S-transferase, nuclear factor erythroid 2-related factor 2, and brain-derived neurotrophic factor striatal contents contrary to NADPH oxidase (NOX2; gp91phox subunit) diminished expression. Moreover, diapocynin mitigated 3-NP-associated neuroinflammation and glial activation with prominent downregulation of nuclear factor-Кβ p65 and marked decrement of inducible nitric oxide synthase content in addition to decreased immunoreactivity of ionized calcium binding adaptor molecule 1 and glial fibrillary acidic protein; markers of microglial and astroglial activation, respectively. Treatment with diapocynin hindered 3-NP-induced apoptosis with prominent decrease in tumor suppressor protein and Bcl-2-associated X protein contents whereas the anti-apoptotic marker; B-cell lymphoma-2 content was noticeably increased. Diapocynin neuroprotective effects could be attributed to silent information regulator 1 upregulation which curbed 3-NP-associated hazards resulting in improved motor functions witnessed during open field, rotarod, and grip strength tests as well as attenuated 3-NP-associated histopathological derangements.ConclusionThe present findings indicated that diapocynin could serve as an auspicious nominee for HD management.Graphical abstract
Process optimization via confidence region: a case study from micro-injection molding
Authors: Trotta Gianluca , Cacace Stefania , Semeraro Quirico 
Published: May 2022

AbstractIn industrial research, experiments are designed to determine the optimal factor levels of the process parameters. Typically, experimental data are used to fit empirical models (for example, regression models) to derive one set of optimal conditions that maximize (or minimize) the response. Unfortunately, the optimization rarely provides a Confidence Interval for the location of the optimal solution, even though the optimal solution itself is subjected to variability. From a practitioner's point of view, identifying a region of possible optimal values provides high operational flexibility to adjust process parameters online during production. This paper provides a procedure for computing a confidence region for the optimal point based on experimental data, bootstrapping, and data depth. The procedure is validated using a case study from micro-injection molding, where the part weight is maximized under a constraint of the probability of flash formation. The proposed method considers that the objective function (part weight) and the constraint (probability of flash formation) are estimated from experimental data and subjected to sampling variability.

Published: May 2022

AbstractBiofilm accumulation on the polymethyl methacrylate (PMMA) restorations negatively affect the prognosis of the provisional restorations or the following treatment. This study developed a novel antibacterial PMMA resin containing low concentration of dimethylaminohexadecyl methacrylate (DMAHDM). Four resins were tested: (1) PMMA resin (Control), (2) 1.25% DMAHDM, (3) 2.5% DMAHDM, (4) 5% DMAHDM. Adding 1.25% DMAHDM into the PMMA resin did not influence the mechanical properties, degree of conversion, monomer releasing, and color stability of the specimens (p > 0.05). The incorporation of DMAHDM into PMMA resin could greatly prevent saliva-derived biofilms adhesion compared with the control group (p < 0.05). The metabolism level of saliva-derived biofilms on the 1.25%, 2.5%, and 5% DMAHDM resins were reduced by 20%, 54%, and 62%, respectively. And the mechanism of DMAHDM disturbing the integrity of bacterial cell walls was confirmed by flow cytometric analysis. Adding 1.25% and 2.5% DMAHDM did not compromise cytocompatibility of the modified resin (p > 0.05). Therefore, novel PMMA resin containing low concentration DMAHDM is promising as a future antimicrobial provisional restoration material for preventing microbial-induced complications in clinical settings.
