Abstract
The concept of 'Hallmarks of Cancer' is an approach of reducing the enormous complexity of cancer to a set of guiding principles. As the underlying mechanism of cancer are portrayed, we find that we gain insight and additional aspects of the disease arise. The understanding of the tumor microenvironment (TME) brought a new dimension and led to the discovery of novel hallmarks such as senescent cells, non-mutational epigenetic reprogramming, polymorphic microbiomes and unlocked phenotypic plasticity. Circular RNAs (circRNAs) are single-stranded, covalently closed RNA molecules that are ubiquitous across all species. Recent studies on the circRNAs have highlighted their crucial function in regulating the formation of human malignancies through a range of biological processes. The primary goal of this review is to clarify the role of circRNAs in the most common form of liver cancer, hepatocellular carcinoma (HCC). This review also addressed the topic of how circRNAs affect HCC hallmarks, including the new generation hallmarks. Finally, the enormous applications that these rapidly expanding ncRNA molecules serve in the functional and molecular development of effective HCC diagnostic biomarkers and therapeutic targets.

Abstract
INTRODUCTION Research into patient and public views on predictive software and its use in healthcare is relatively new. This study aimed to understand older adults' acceptability of an opportunistic bone density assessment for osteoporosis diagnosis (IBEX BH), views on its integration into healthcare, and views on predictive software and AI in healthcare. METHODS Focus groups were conducted with participants aged over 50 years, based in South West England. Data were analysed using thematic analysis. Analysis was informed by the theoretical framework of acceptability. RESULTS Two focus groups were undertaken with a total of 14 participants. Overall, the participants were generally positive about the IBEX BH software, and predictive software's in general stating 'it sounds like a brilliant idea'. Although participants did not understand the intricacies of the software, they did not feel they needed to. Concerns about IBEX BH focussed more on the clinical indications of the software (e.g. more scans or medications), with participants expressing less trust in results if they indicated medication. Questions were also raised about how and who would receive the results of this software. Individual choice was evident in these discussions, however most indicated the preferences for spoken communication 'But I would expect that these results would be given by a human to another human.' CONCLUSIONS Focus group participants were generally accepting of the use of predictive software in healthcare. IMPLICATIONS FOR PRACTICE Thought and care needs to be taken when integrating predictive software into practice. Focusses on empowering patients, providing information on processes and results are key.

Abstract
Metastasis is the principal cause of cancer death, yet we lack an understanding of metastatic cell states, their relationship to primary tumor states, and the mechanisms by which they transition. In a cohort of biospecimen trios from same-patient normal colon, primary and metastatic colorectal cancer, we show that while primary tumors largely adopt LGR5 + intestinal stem-like states, metastases display progressive plasticity. Loss of intestinal cell states is accompanied by reprogramming into a highly conserved fetal progenitor state, followed by non-canonical differentiation into divergent squamous and neuroendocrine-like states, which is exacerbated by chemotherapy and associated with poor patient survival. Using matched patient-derived organoids, we demonstrate that metastatic cancer cells exhibit greater cell-autonomous multilineage differentiation potential in response to microenvironment cues than their intestinal lineage-restricted primary tumor counterparts. We identify PROX1 as a stabilizer of intestinal lineage in the fetal progenitor state, whose downregulation licenses non-canonical reprogramming.

Abstract
PURPOSE To compare the macular and papillary parameters on optical coherence tomography (OCT) between the amblyopic eye and the healthy eye in subjects with unilateral strabismic or anisometropic amblyopia. PATIENTS AND METHODS This is a cross-sectional and comparative study carried out over two years, from April 1, 2019, to March 31, 2021. We included patients aged over 5years, followed for unilateral amblyopia, free of any neurological and/or ocular pathology. The evaluation of the macular and papillary parameters in the amblyopic and healthy eyes was performed with Swept-Source Optical Coherence Tomography (OCT-SS). The parameters were compared according to age group and type of amblyopia. RESULTS We collected 50 patients, 29 children, and 21 adults, with a mean age of 19.8years. Amblyopia was secondary to anisometropia in 40 patients and strabismus in 10 patients. Analysis of macular tomographic parameters found no significant difference between amblyopic eyes and healthy eyes for mean macular thickness (P=0.86), central macular thickness (P=0.86), or mean macular volume (P=0.54). The mean retinal peripapillary fiber thickness (RNFL) was 107.48μm in the amblyopic eye and 103.8μm in the healthy eye, with a statistically significant difference (P<0.001). This significant thickening of the RNFL in amblyopic eyes was present in adults (P<0.001), children (P<0.001), anisometropic (P<0.001), and strabismic amblyopia (P=0.024). Analysis of the other optic nerve head parameters revealed no significant difference between amblyopic eyes and healthy eyes in terms of optic disc surface area (P=0.89), neuro-retinal annulus surface area (P=0.47), vertical (P=0.98) or horizontal (P=0.74) cup to disc ratio. CONCLUSION Amblyopia is accompanied by thickening of the peripapillary retinal fibers without macular repercussions. However, larger prospective studies are needed to confirm these results.

Abstract
Abstract
Aim
This study examines the safety and timing initiating VTE prophylaxis post traumatic splenic injuries (TSI).
Method
Patients with TSI were identified from prospectively maintained Trauma Audit and Research Network (TARN) database from 2015–2020 in a single tertiary trauma centre. Clinical and radio-logical information were collected retrospectively. TSI were graded using American Association for the Surgery of Trauma (AAST) splenic injury scale. Chemical venous thromboprophylaxis initiation were categorised as not given, <48h and >48h following the injury.
Results
In total 102 patient were included out of 136 patients identified with TSI. 34 patients were excluded for lack of electronic data, palliative decision, or fatal condition on arrival. 12 patients out of 102 required operative management (OM) and 90 patients NOM. VTE prophylaxis was not given for 31 (30.4%). Medical reasons for this include severe brain injury and early discharge before 48 hours. VTE prophylaxis was initiated for 37 (36.3%) patients within 48 hours, and for 34 patients (33.3%) after 48 hours of admission. Seven patients developed thromboembolic events, majority of which (6/7) received VTE prophylaxis after 48 hours. Importantly, none of the patients who received VTE prophylaxis had rebleeding.
Conclusions
This study showed that early initiation of chemical VTE prophylaxis (<48h) is safe, resulted in lower incidence of DVTs/PEs without increasing the risk of bleeding. Results from this study supports recommendation from other studies 1 to initiate chemical VTE prophylaxis after TSI as early as 24h post injury with no other contra-indications.

Abstract
Abstract
Aim
Pedicle screws provide excellent fixation for a wide range of indications; their adoption in the cervical spine has been slower than in the thoracic and lumbar spine, largely due to the smaller pedicle sizes and proximity to neurovascular structures in the neck. Recent years have seen the development of technology to improve accuracy and thereby safety in cervical pedicle screw placement over traditional fluoroscopic techniques, including intraoperative 3D navigation, computer assisted systems and physical templates with screw guides. We have performed a systematic review into the accuracy rates of the various systems.
Method
PubMed and Cochrane Library databases were searched; keywords "pedicle screw cervical spine" were searched; 9 valid papers involving 1427 screws were found.
Results
Accuracy rates were 80.6% for fluoroscopy, 91.4% for navigation methods, and 96.7% for templates.
Conclusions
Superior results for templates are complemented by reduced radiation exposure to patient and surgeon; however, the technology requires prolonged pre-operative planning to create the bespoke template, and the development of an infrastructure to allow for their rapid production and delivery is needed before they become more widely available.
Two broad methods of navigation currently exist: intraoperative CT scanning providing real-time 3D navigation and preoperative CT registration in relation to a fixed reference with intraoperative computer assistance. At present, these methods are more commonly used, due to their proven improved accuracy rates over fluoroscopy, availability in emergencies and alongside minimally invasive techniques.
Despite their novelty and limitations, templates provide promising accuracy scores, although practical considerations may inhibit their proliferation.

Abstract
The aim of this study was to produce high yield of a local bacterial alkaline protease in the yeast system because the scientific involvement of microorganisms in enzyme production is still not given enough attention in Saudi Arabia. Soil samples were collected from the rhizosphere of some desert plants in Saudi Arabia. Ninety-three alkaline protease producing bacterial isolates were recovered on skimmed-milk agar at pH 9.4 and 45°C for 48 hr. Isolate D9 obtained from the rhizosphere of Heliotropium digynum at Dhahran City was the most potent isolate in respect to enzyme productivity (184.6 U/ml). The full gene of alkaline protease was amplified and showed the expected size (1300 bp). Restriction enzymes analysis also verified the integrity of the PCR product. The sequence of the protease gene revealed an open reading frame of 1329 nt correspond to the full length of the protease gene of isolate D9 encoding a 443 aa protein. After ligation of the amplified gene by the TA cloning method, digestion with appropriate restriction enzymes confirmed the integrity of the cloned gene. The insert was prepared by two PCRs that were conducted with a pair of primers specifically designed for this purpose. The digested and purified cloning vector pRS426/GAL1p-207-Glu-MS was ligated with the insert then transformed into various strains of Saccharomyces cerevisiae via the electroporation method. Maximum protease expression was done by recombinant OS303 in galactose containing media (145.5 U/ml) with an approximately 2-fold increase when compared with the wild OS303 strain., this may be due to ability to activate gal operon.

Abstract
Abstract
Aim
Gallstone related disease accounts for a third of the admissions to the Surgical Department. In June 2019, a clinical audit was undertaken at Great Western Hospital assessing the number of patients who underwent cholecystectomy, following initial diagnosis, in accordance to current guidelines. The results demonstrated a very low number of patients had cholecystectomy, within the targeted time frame, which led to the implementation of a dedicated operative “hot gallbladder” list weekly. In June 2020, we re-audit the service to evaluate the impact of the change implemented.
Method
A retrospective observational analysis of patients admitted to the Hospital in June 2020 with gallstone related disease. Data was collected using the Surgical on-call lists, these were analysed and patients selected according to the reason for admission, only gallstone related issues were considered in this analysis. Finally, via Medway, the time from admission to surgery was assessed.
Results
Despite the disruption in service provision due to COVID-19, the implementation of the “hot gallbladder” list led to a 10.7% increase in timely cholecystectomies, bringing the overall compliance to 14%. There was also a significant reduction in biliary relate re-admissions, from 58% to 37%. Despite 47.3% of patients were still awaiting surgery, the waiting list was reduced by 5.2% in only 1 year.
Conclusions
This study demonstrated that the implementation of the “hot gallbladder” list has improved the compliance with the current guidelines. The change has brought us in line with the national average of 15%, as estimated by RCSEng, therefore demonstrating the efficacy of the weekly list.

Abstract
OBJECTIVE This study evaluated the efficacy of the soluble epoxide hydrolase (sEH) inhibitor, TPPU on chronic NG-Nitro L-arginine methyl ester (L-NAME)-induced hypertension in rats and its effects on plasma Angiotensin II (Ang II), cardiac Angiotensin-converting enzyme (ACE) and Angiotensin II receptor type 1 (AT1R) expressions. MATERIALS AND METHODS Forty Sprague Dawley rats were divided into 5 groups. Two groups served as control and received orally either vehicle or TPPU (3 mg/kg) for five weeks. The other three groups were given L-NAME (50 mg/kg/day) in drinking water for five weeks. Two weeks after the L-NAME treatment, animals received orally either saline or TPPU (3 mg/kg/day) or lisinopril (10 mg/kg/day) daily for 3 weeks. Blood pressure (BP) was measured weekly. At the end of the experiment, plasma Ang II, cardiac ACE and AT1R protein and gene expressions were determined. RESULTS L-NAME caused a significant increase in BP of the animals. TPPU and lisinopril resulted in normalization of L-NAME-induced hypertension. They also caused a significant reduction in Ang II and ACE protein and gene expressions compared to L-NAME and vehicle-treated animals. CONCLUSIONS This study demonstrates that TPPU effectively lowers L-NAME-induced hypertension in rats. The mechanism of its antihypertensive effect is likely mediated by the suppression of ACE gene and protein expression, leading to a lower Ang II level.

Abstract
Abstract
Background
Cardiac nerves regulate many important physiological functions of the heart such as heart rate and contractility. The emerging role of cardiac nerves during tissue homeostasis and regeneration is beginning to be appreciated. We discovered that neonatal mice are capable of regenerating their hearts following injury within a brief period after birth by proliferation of the pre-existing cardiomyocytes. Furthermore, we have demonstrated that cholinergic nerves play an important role in guiding the neonatal heart regenerative response. However, the adult mammalian heart, including the human heart, is incapable of regeneration following injury. Thus, there is great excitement about understanding the evolutionarily conserved mechanisms of endogenous cardiac regeneration, so that we can explore potential avenues to reawaken this process in adult humans.
Purpose
Our overarching goal is to define the mechanisms by which cholinergic nerves regulate heart regeneration following ischemic injury by using the neonatal mouse heart regeneration model. These studies will uncover novel pathways by which cholinergic signaling promotes cardiomyocyte proliferation and heart regeneration, which holds significant therapeutic potential for treatment of adult heart disease.
Methods
In this project, we employed genetically engineered mouse models of the critical receptors for cholinergic signaling in the heart to define the mechanisms of cholinergic nerve regulation of heart regeneration. First, we generated a cardiomyocyte-specific deletion of the muscarinic receptor (M2), the most predominant muscarinic receptor subtype present in the heart. In addition, we utilized the α7 nicotinic receptor (Chrna7) knockout mice to study the role of Chrna7 in endogenous immune cells, which is the main mediator of the cholinergic anti-inflammatory pathway. These mouse models will address how cholinergic nerves regulate heart regeneration via the M2 muscarinic receptor signaling and the inflammatory response following injury.
Results
Our results demonstrate that inhibition of two different cholinergic receptors (muscarinic and nicotinic) results in a reduction in cardiomyocyte proliferation and inhibition of the neonatal cardiac regenerative response following injury. More importantly, we demonstrate that cholinergic signaling mediates the cardiac regenerative response mainly through suppression of pro-inflammatory cytokines via the cholinergic anti-inflammatory pathway.
Conclusions
Cholinergic nerve signaling plays an important role in mounting a robust cardiac regenerative response following injury. These results have significant therapeutic potential, which will forge new paradigms with respect to the role of cardiac nerves during mammalian cardiac regeneration and reveal potential mechanisms regarding the benefits of nerve stimulation following cardiac injury in humans.

Abstract
OBJECTIVE The current study aims to compare the rate of intraoperative nausea and vomiting after repeat cesarean delivery (CD) under two different approaches: by intraperitoneal incision repair or by uterus exteriorization for incision reapair. MATERIALS AND METHODS We conducted a single-blinded randomized clinical trial (NCT03009994) at a tertiary University Hospital between the 1st of September 2016 and the 31st of December 2017. The study included pregnant women at term of gestation (>37 weeks) scheduled for repeat CD under spinal anesthesia. Women were assigned to either uterine exteriorization for incision repair (Group I) or intraperitoneal incision repair (Group II). The primary assessed was the rate of nausea and vomiting during CD. RESULTS The study included 1028 women in the final analysis. The rate of intraoperative nausea and vomiting was significantly lower in the intraperitoneal repair group compared to the exteriorization group (24% versus 38.7%, p= 0.001). Likewise, occurrence of uterine atony and the need for additional uterotonics were significantly lower in the intraperitoneal repair group (p= 0.001 and 0.02 respectively). Postoperatively, the rate of nausea and vomiting (12.6 % versus 21 %; P=0.001), and the time to the first recognized bowel movement (12.3 hours versus 14.1 hours; P=0.003) were significantly lower in the intraperitoneal repair group compared to the exteriorization group. CONCLUSIONS Intraperitoneal repair of the uterine incision during repeat CD is beneficial compared to exteriorization. Improvements in the rate of intra- and postoperative nausea, vomiting, uterine atony and time to the first recognized bowel movement were observed in patients operated with this technique.

Abstract
Intellectual disability (ID) is a measurable phenotypic consequence of genetic and environmental factors. In this study, we prospectively assessed the diagnostic yield of genomic tools (molecular karyotyping, multi-gene panel and exome sequencing) in a cohort of 337 ID subjects as a first-tier test and compared it with a standard clinical evaluation performed in parallel. Standard clinical evaluation suggested a diagnosis in 16% of cases (54/337) but only 70% of these (38/54) were subsequently confirmed. On the other hand, the genomic approach revealed a likely diagnosis in 58% (n=196). These included copy number variants in 14% (n=54, 15% are novel), and point mutations revealed by multi-gene panel and exome sequencing in the remaining 43% (1% were found to have Fragile-X). The identified point mutations were mostly recessive (n=117, 81%), consistent with the high consanguinity of the study cohort, but also X-linked (n=8, 6%) and de novo dominant (n=19, 13%). When applied directly on all cases with negative molecular karyotyping, the diagnostic yield of exome sequencing was 60% (77/129). Exome sequencing also identified likely pathogenic variants in three novel candidate genes (DENND5A, NEMF and DNHD1) each of which harbored independent homozygous mutations in patients with overlapping phenotypes. In addition, exome sequencing revealed de novo and recessive variants in 32 genes (MAMDC2, TUBAL3, CPNE6, KLHL24, USP2, PIP5K1A, UBE4A, TP53TG5, ATOH1, C16ORF90, SLC39A14, TRERF1, RGL1, CDH11, SYDE2, HIRA, FEZF2, PROCA1, PIANP, PLK2, QRFPR, AP3B2, NUDT2, UFC1, BTN3A2, TADA1, ARFGEF3, FAM160B1, ZMYM5, SLC45A1, ARHGAP33 and CAPS2), which we highlight as potential candidates on the basis of several lines of evidence, and one of these genes (SLC39A14) was biallelically inactivated in a potentially treatable form of hypermanganesemia and neurodegeneration. Finally, likely causal variants in previously published candidate genes were identified (ASTN1, HELZ, THOC6, WDR45B, ADRA2B and CLIP1), thus supporting their involvement in ID pathogenesis. Our results expand the morbid genome of ID and support the adoption of genomics as a first-tier test for individuals with ID.

Abstract
Permanent deformation in bending is associated with the development of residual stresses. The objective of this study was to characterize those residual stresses and test whether they can be manipulated to extend the fatigue lives of cast clasps. Simulations with validated non-linear finite element models were used to characterize the residual stresses in clasps cast from Ti-6Al-7Nb, Co-Cr, and Type IV gold alloys. In addition, two groups of as-cast and pre-overloaded (subjected to a load that produced 20 μm of permanent deformation) Ti-6Al-7Nb clasps (10 specimens each) were subjected to cyclic 0.5-mm deflections at 5 Hz until fatigue. Pre-overloaded specimens demonstrated significantly longer fatigue lives (32,200 ± 17,300 cycles) than did those tested in the as-cast condition (17,900 ± 7600 cycles), consistent with the maximum tensile stress values revealed by finite element analysis.

Abstract
OBJECTIVE To study socio-demographic characteristics and main causes related to visual impairment (VI) as a function of age bracket and to analyze their trends over time in the district of Mahdia. METHOD A retrospective review was performed on 1487 cases of visual impairment registered with the social authorities in Mahdia, between 1980 and 2013. The social, demographic, vision exam findings and causes were ascertained and analyzed in an SPSS database. Incidence rates of VI and blindness due to various causes were calculated based on the demographic data from the NSI to estimate the time trends using the general linear regression model and Spearman correlation. RESULTS Analyses included 1487 participants with a median age of 47 years, 40.6% of cases were aged under 45 years. Children accounted for 11.1% (165 patients), while age was between 16 and 45 years in 29.5% (439 patients), between 46 and 65 years in 31.5% (469 patients) and greater than 65 years in 27.8% (414 patients). The sex-ratio (M/F) was 1.78. Socially, 51% came from rural areas, 62% were illiterate, and 84% were unemployed. We observed blindness in 70% of participants and low vision in 30%. In children, the causes were dominated by congenital cataract and congenital glaucoma, each present in 31 children (18.8%). Between 16 and 45 years, glaucoma and hereditary dystrophies of the retina were found in 62 and 61 patients respectively (14% each). For age between 46 and 65 years, trachoma was responsible for 19.8% of cases of VI, glaucoma in 15.8% and cataract in 15.1%. Beyond 65 years, glaucoma accounted for 30.7% of the causes of VI and cataract 27.8% of cases. Trend analysis shows a significant increase in the incidence rate of visual impairment with an average of 12% per year (P=0.001). The mean age increased by 46% (P=0.003). Trachoma increased by 118% (P<0.0001) between 1980 and 1990, then declined by 42% (P=0.0013) between 1991 and 2013. Incidence of VI significantly increased by 4% for cataract (P=0.001), 23% (P=0.001) for glaucoma and 20% (P=0.02) for diabetic retinopathy, while VI related to refractive errors and AMD showed no significant change. CONCLUSION Advanced age, lower educational and socio-economic status were associated with bilateral VI. Age related eye problems are the main causes of VI, and their incidence is tending to increase. Public health policies and procedures should be targeted to risk related populations and age-related diseases in order to control the incidence of visual impairment and avoid its consequences.

Abstract
OBJECTIVES The aim of the current study is to collect scientific data on all branded hyaluronic acid (HA) products in Italy that are in use for intra-articular (IA) injection in osteoarthritis (OA) compared with that reported in the leaflet. METHODS An extensive literature research was performed for all articles reporting data on the IA use of HA in OA. Selected studies were taken into consideration only if they are related to products based on HAs that are currently marketed in Italy with the specific joint indication for IA use in patients affected by OA. RESULTS Sixty-two HA products are marketed in Italy: 30 products are indicated for the knee but only 8 were proved with some efficacy; 9 products were effective for the hip but only 6 had hip indication; 7 products proved to be effective for the shoulder but only 3 had the indication; 5 products proved effective for the ankle but only one had the indication; 6 products were effective for the temporomandibular joint but only 2 had the indication; only 2 proved effective for vertebral facet joints but only 1 had the indication; and 5 products proved effective for the carpometacarpal joint but only 2 had the indication. CONCLUSIONS There are only a few products with some evidences, while the majority of products remain without proof. Clinicians and regulators should request postmarketing studies from pharmaceuticals to corroborate with that reported in the leaflet and to gather more data, allowing the clinicians to choose the adequate product for the patient.

Abstract
The long-term intake of a judiciously composed nutriceutical containing low-dose vitamins, antioxidants, minerals and particular herbal preparations seems justified for older persons who take medication, or who consume an unbalanced diet, or who are exposed to environmental toxins. Recent reports suggest these nutriceuticals may delay age-related diseases and the occurrence of cancer, and reduce mortality in apparently healthy ageing men. Food supplementation with a nutriceutical that was formulated particularly for ageing men should result in an increase of at least one quality-adjusted life year and may lower the financial and social burden of disease in elderly people.

Abstract
Theranostic nanoparticles with both therapeutic and imaging abilities have the promise to revolutionize diagnosis, therapy, and prognosis. Early and accurate detection along with swift treatment are the most important steps in the successful treatment of any disease. Over the last decade, a variety of nanotechnology-based platforms have been created in the hope of improving the treatment and diagnosis of a wide variety of diseases. However, significant hurdles still remain before theranostic nanoparticles can bring clinical solutions to the fight against chronic respiratory diseases. Some fundamental issues such as long-term toxicity, a precise understanding of the accumulation, degradation and clearance of these particles, and the correlation between basic physicochemical properties of these nanoparticles and their in vivo behavior have to be fully understood before they can be used clinically. To date, very little theranostic nanoparticle research has focused on the treatment and diagnosis of chronic respiratory illnesses. Nanomedicine approaches incorporating these theranostic nanoparticles could potentially be translated into clinical advances to improve diagnosis and treatment of these chronic respiratory diseases and enhance quality of life for the patients.

Abstract
A computational strategy is devised for the accurate ab initio simulation of elastic properties of crystalline materials under pressure. The proposed scheme, based on the evaluation of the analytical stress tensor and on the automated computation of pressure-dependent elastic stiffness constants, is implemented in the CRYSTAL solid state quantum-chemical program. Elastic constants and related properties (bulk, shear and Young moduli, directional seismic wave velocities, elastic anisotropy index, Poisson's ratio, etc.) can be computed for crystals of any space group of symmetry. We apply such a technique to the study of high-pressure elastic properties of three silicate garnet end-members (namely, pyrope, grossular, and andradite) which are of great geophysical interest, being among the most important rock-forming minerals. The reliability of this theoretical approach is proved by comparing with available experimental measurements. The description of high-pressure properties provided by several equations of state is also critically discussed.
