Abstract
BACKGROUND: Peripheral arterial disease (PAD) is more prevalent and often presents as more severe in patients with diabetes mellitus (DM) compared with those without DM. Although some patients may be asymptomatic, symptoms ranging from exertional leg heaviness and fatigue to acute limb loss are possible. PAD has significant physical and psychiatric health consequences, thus management with medical therapy and lifestyle changes are indicated. However, peripheral vascular intervention (PVI) is an increasingly popular method used in patients failing conservative management. The association of PVI with health status in diabetic patients has yet to be determined.
METHODS: We analyzed the clinical response to PVI in DM (n=203, 52%) compared with non-DM patients (n=183, 48%), using the Peripheral Arterial Questionnaire (PAQ) for patients during baseline and a maximum 6 months after PVI. 502 patients participated with an exclusion of 116 patients from our analysis due to progression of acute limb ischemia and incomplete data collection. Our finalized study population comprised 386 consecutive patients with symptomatic PAD who had also received PVI treatment during the aforementioned time frame. Our patient population received PVI treatment in the year 2012 at the St. John Hospital and Medical Center in Detroit, MI. We used the PAQ summary score, which summarizes the patients’ level of physical and social function, patient symptoms, and overall quality of life before and after the procedure. This represented the PAD-related Quality of Health (QOH). Our score range is between 0 (lowest health quality) and 100 (highest health quality).
RESULTS: Compared with non-DM patients, those with DM were more likely to have a history of prior PVI, an increased prevalence of PAD risk factors, and significantly lower QOH scores at baseline (32.7 +/- 20 vs 37.5 +/- 20.6, p=0.02). After adjustment for baseline confounding, neither the baseline, the change, nor the final summary scores were significantly different between groups. This suggests similar symptomatic and functional improvement in non-DM and DM patients post-PVI.
CONCLUSIONS: Following PVI, PAD-specific health status showed a similar improvement in patients with and without DM, illustrating that use of this strategy among patients with multiple comorbidities or diffuse PAD as useful.

Abstract
BACKGROUND Talus fractures are rare (<1% of all fractures), and their rarity limits the number of studies available to guide management. In instances such as this, cadaveric studies can play an important role. The purpose of this scoping review was to identify and describe the current body of literature on cadaveric studies of fractures of the talus. METHODS Through multiple electronic database searches (Medline, Embase, Scopus) we identified a broad body of cadaveric research into talus fractures, and these were classified into 4 main themes. Study characteristics were summarised along with any descriptive results and conclusions. RESULTS The search yielded 484 articles of which 19 met the inclusion criteria. They provide valuable insights into benefits and drawbacks of surgical approaches to the talus, particularly with regard to direct visualisation of anatomic reduction, and risks of neurovascular or tendon compromise. For talar neck fractures it is clear that cannulated screws offer superior fixation over plates, however, are inferior when considering anatomic reduction of the fracture. Direct visualisation of fracture reduction is far superior to intraoperative radiographic assessment, and mal-reduction leads to reduced subtalar joint range of motion, midfoot deformity, and increased joint contact pressures. CONCLUSIONS This study provides a summary of the existing literature surrounding the use of cadaver studies in fractures of the talus. We have identified gaps in the literature, particularly surrounding strength of fixation of new locking plate fixation techniques.

Abstract
As an alternative to fossil fuels, biodiesel can be a source of clean and environmentally friendly energy source. However, its commercial application is limited by expensive feedstock and the slow nature of the pretreatment step-acid catalysis. The conventional approach to carry out this reaction uses stirred tank reactors. Recently, the lab-scale experiments using microbubble mediated mass transfer technology have demonstrated its potential use at commercial scale. However, all the studies conducted so far have been at a lab scale~100 mL of feedstock. To analyze the feasibility of microbubble technology, a larger pilot scale study is required. In this context, a kinetic study of microbubble technology at an intermediate scale is conducted (3 L of oil). Owing to the target for industrial application of the process, a commercial feedstock (Spirulina), microalgae oil (MO) and a commercial catalyst para-toluene sulfonic acid (PTSA) are used. Experiments to characterize the kinetics space (response surface, RSM) required for up-scaling are designed to develop a robust model. The model is compared with that developed by the gated recurrent unit (GRU) method. The maximum biodiesel conversion of 99.45 ± 1.3% is achieved by using these conditions: the molar ratio of MO to MeOH of 1:23.73 ratio, time of 60 min, and a catalyst loading of 3.3 wt% MO with an MO volume of 3 L. Furthermore, predicted models of RSM and GRU show proper fits to the experimental result. It was found that GRU produced a more accurate and robust model with correlation coefficient R2 = 0.9999 and root-mean-squared error (RSME) = 0.0515 in comparison with RSM model with R2 = 0.9844 and RMSE = 3.0832, respectively. Although RSM and GRU are fully empirical representations, they can be used for reactor up-scaling horizontally with microbubbles if the liquid layer height is held constant while the microbubble injection replicates along the floor of the reactor vessel-maintaining the tessellation pattern of the smaller vessel. This scaling approach maintains the local mixing profile, which is the major uncontrolled variable in conventional stirred tank reactor up-scaling.

Abstract
Abstract
Introduction/Objective
Numerous SARS-CoV-2 variants/lineages have been identified based on genome sequencing. As of June 15, 2022 almost 11,399,573 whole genome sequences have been deposited in the GISAID-database. Severity and spread of COVID19 is based on their efficiency of infection and to multiply in host. That largely depend upon the structural mutation in spike, ORF and N proteins etc. That happens due to translation of genomic mutations during polypeptide synthesis. Also, the mutations are region/country specific. Specific mutation and combination of mutation causes the emergence of new strains. However, the strains can migrate from one region to other through travelers. The main objective of the current study is profiling of mutations in the genome of SARSCoV2 using Next- Generation-Sequencing (NGS) in international travelers and phylogenetic analysis of the sequences to find out different clades of SARSCoV2.
Methods/Case Report
A total of 557 SARSCoV2 genomes were sequenced on S4-sequencing flow-cell on NovaSeq 6000. For NGS of SARS-CoV-2 genome, Illumina, COVIDSeq kits and the protocols will be used strictly as recommended by the manufacturer. After NGS the analysis was done followed by FASTA sequences retrieval, mutations recording and phylogeny.
Results (if a Case Study enter NA)
This study reports 11 clades (19A, B, 20A, B, C, D, 20E; EU1, 20G, 20H; Beta V2, 20I: Alpha V1, 21D; and Eta) for the first time in international travelers. To best of our knowledge, this is the first report of the COVIDSeq approach for detection of mutation in SARSCoV2 genomic clades. The study revealed some dominants mutations was (Orf1a: P2018Q, K1053R, E176V, Orf1b: A520V, T2165A, S: D1127G, D614G, L18F etc. in other genes).
Conclusion
Profiling of common mutations among travelers could fill some gaps about the existence of SARS-CoV-2 variants information. However, further studies are needed to consolidate these findings before to be utilized for development of a potential therapeutic strategy.

Abstract
Multi-resistant pathogenic strains of non-lactose fermenting Escherichia coli (NLF E. coli) are responsible for various intestinal and extraintestinal infections. Although several studies have characterised such strains using conventional methods, they have not been comprehensively studied at the genomic level. To address this gap, we used whole-genome sequencing (WGS) coupled with detailed microbiological and biochemical testing to investigate 17 NLF E. coli from a diagnostic centre (icddr,b) in Dhaka, Bangladesh. The prevalence of NLF E. coli was 10%, of which 47% (8/17) exhibited multi-drug resistant (MDR) phenotypes. All isolates (17/17) were confirmed as E. coli and could not ferment lactose sugar. WGS data analysis revealed international high-risk clonal lineages. The most prevalent sequence types (STs) were ST131 (23%), ST1193 (18%), ST12 (18%), ST501 (12%), ST167 (6%), ST73 (6%) and ST12 (6%). Phylogenetic analysis corroborated a striking clonal population amongst the studied NLF E. coli isolates. The predominant phylogroup detected was B2 (65%). The bla CTX-M-15 extended-spectrum beta-lactamase gene was present in 53% of isolates (9/17), whilst 64.7% (11/17) isolates were affiliated with pathogenic pathotypes. All extraintestinal pathogenic E. coli pathotypes demonstrated β-hemolysis. Our study underscores the presence of critical pathogens and MDR clones amongst non-lactose fermenting E. coli. We suggest that non-lactose fermenting E. coli be considered equally capable as lactose fermenting forms in causing intestinal and extraintestinal infections. Further, there is a need to undertake systematic, unbiased monitoring of predominant lineages amongst non-lactose fermenting E. coli that would help in better treatment and prevention strategies.

Abstract
An overwhelming number of research articles have reported a strong relationship of the microbiome with cancer. Microbes have been observed more commonly in the body fluids like urine, stool, mucus of people with cancer compared to the healthy controls. The microbiota is responsible for both progression and suppression activities of various diseases. Thus, to maintain healthy human physiology, host and microbiota relationship should be in a balanced state. Any disturbance in this equilibrium, referred as microbiome dysbiosis becomes a prime cause for the human body to become more prone to immunodeficiency and cancer. It is well established that some of these microbes are the causative agents, whereas others may encourage the formation of tumours, but very little is known about how these microbial communications causing change at gene and epigenome level and trigger as well as encourage the tumour growth. Various studies have reported that microbes in the gut influence DNA methylation, DNA repair and DNA damage. The genes and pathways that are altered by gut microbes are also associated with cancer advancement, predominantly those implicated in cell growth and cell signalling pathways. This study exhaustively reviews the current research advancements in understanding of dysbiosis linked with colon, lung, ovarian, breast cancers and insights into the potential molecular targets of the microbiome promoting carcinogenesis, the epigenetic alterations of various potential targets by altered microbiota, as well as the role of various chemopreventive agents for timely prevention and customized treatment against various types of cancers.

Abstract
OBJECTIVE The current study intends to find out the efficacy of Orlistat in the management of hyperlipidemia, Systolic Blood Pressure (SBP) and Body Mass Index (BMI). MATERIALS AND METHODS This retrospective study has evaluated the lipid profiles of the patients, who have been using metformin therapy for Type 2 diabetes. The study has obtained data regarding the parameters like triglyceride, Total cholesterol (TC), LDL cholesterol, HDL cholesterol and LDL/HDL ratio, systolic blood pressure and Body Mass Index (BMI). Random distribution of patients was done into placebo and Orlistat groups. The placebo group received only metformin, and patients in the Orlistat group received Orlistat along with metformin. After 24 weeks, the follow-up study was done, and statistical analysis was conducted. RESULTS The study found that the Orlistat group has significant improvement (p<0.05) more improvement in LDL cholesterol, HDL cholesterol, Total cholesterol, LDL/HDL Ratio and Triglycerides, while BMI and systolic blood pressure did not show a significant difference between placebo and Orlistat group. CONCLUSIONS This study has concluded that Orlistat can be used for significant improvement in lipid profile. The study also found that Orlistat may not have a significant effect on reducing BMI and blood pressure without adequate lifestyle modification.

Abstract
Abstract
Background
Generic prescribing is cost-effective, and evidence suggests that clinical outcomes compared with brand name products are largely equivalent. Hospital guidelines recommend that medications should be prescribed using the approved generic name, not the brand name. There are some exceptions to this. Anecdotal evidence suggests that medication reconciliation for patients on admission to hospital are charted by brand name rather than the generic title. To investigate this we conducted a four-day audit of the prescribing of medications on patients admitted to medical wards in an acute hospital.
Methods
This audit took place over a four-day period. The Kardex of each patient admitted to the three medical wards was reviewed. Patients admitted under cardiology, haematology and oncology were excluded. All medications including whether they were prescribed using the generic or brand name were collected. Statistical analysis was carried out using Microsoft Excel.
Results
A total of 33 kardexes were collected. Two hundred and fifty-seven prescribed medications were reviewed. Ninety-five were charted as brand names and 63% (n=162) were prescribed using the generic name. One hundred and eighteen different categories of medications were prescribed. Enoxaparin was prescribed using the brand name ten times and the generic title three times. The antibiotic Piperacillin/tazobactam was prescribed three times using the brand name and one time using the generic title. Of the eight times atorvastatin was prescribed, it was charted using the generic name seven times (88%).
Conclusion
Almost two-thirds of medications for patients admitted to medical wards are prescribed using generic titles. However, there is room for improvement. Of note, commonly prescribed medications such as enoxaparin and certain antimicrobials were prescribed using the brand name. Opportunities e.g., induction, grand rounds and Non-Consultant Hospital Doctor (NCHD) teaching sessions should be utilised to provide education on the importance of generic prescribing to all NCHDs admitting patients.

Abstract
380 Background: Despite increasing use of breast cancer (BRCA) gene and homologous recombination deficiency/ homologous recombination repair gene mutation(s) (HRD/HRRm) testing, barriers to uniform adoption of these tests to inform patient management remain. The purpose of this study was to identify potential barriers to BRCA, HRD, and HRRm testing from the physician’s perspective. Methods: A cross-sectional online survey was sent to a US representative sample of primary care providers, medical oncologists, urologists, and surgeons, including both users and non-users of the tests. Physician demographics, practice characteristics, barriers (reimbursement, knowledge, logistical), and strategies to alleviate barriers were collected. Descriptive analysis was conducted via SASv9.4. Results: Three hundred physicians participated in this survey (49.7 years of age and 17.9 years in clinical practice on average). Most respondents (94.3%) reported at least 1 barrier to test use (BRCA 94.0%, HRD 91.3%, HRRm 90.3%). The most common barrier was the challenge in obtaining prior authorizations (BRCA 74.0%, HRD 80.0%, HRRm 83.5%). Other commonly reported barriers included test not being covered by insurance (BRCA 64.8%, HRD 61.8%, HRRm 67.6%), insurance policies restricting certain genomic tests to a particular lab/test provider (BRCA 64.0%, HRD 66.5%, HRRm 67.4%), and unclear/inconsistent payer policies for test coverage (BRCA 63.6%, HRD 63.6%, HRRm 66.7%). Physicians were more likely to report barriers to HRD/HRRm testing compared to BRCA testing. More reimbursement-related barriers were reported by primary care providers vs. other physicians. Physician/patient education, collaboration with specialists, standardization in test guidelines, and improvement in test interpretation were reported as key strategies to improving further test adoption in patient management. Conclusions: The results highlight that physicians have concerns about reimbursement-related, knowledge-related, and logistical barriers that may impact clinical optimization. Addressing these barriers to improve oncology care is of utmost importance.[Table: see text]

Abstract
PURPOSE Glutaminase is a key enzyme, which supports elevated dependency of tumors on glutamine-dependent biosynthesis of metabolic intermediates. Dual targeting of glucose and glutamine metabolism by the mTOR inhibitor everolimus plus the oral glutaminase inhibitor telaglenastat showed preclinical synergistic anticancer effects, which translated to encouraging safety and efficacy findings in a phase I trial of 2L+ renal cell carcinoma (RCC). This study evaluated telaglenastat plus everolimus (TelaE) versus placebo plus everolimus (PboE) in patients with advanced/metastatic RCC (mRCC) in the 3L+ setting (NCT03163667). PATIENTS AND METHODS Eligible patients with mRCC, previously treated with at least two prior lines of therapy [including ≥1 VEGFR-targeted tyrosine kinase inhibitor (TKI)] were randomized 2:1 to receive E, plus Tela or Pbo, until disease progression or unacceptable toxicity. Primary endpoint was investigator-assessed progression-free survival (PFS; one-sided α <0.2). RESULTS Sixty-nine patients were randomized (46 TelaE, 23 PboE). Patients had a median three prior lines of therapy, including TKIs (100%) and checkpoint inhibitors (88%). At median follow-up of 7.5 months, median PFS was 3.8 months for TelaE versus 1.9 months for PboE [HR, 0.64; 95% confidence interval (CI), 0.34-1.20; one-sided P = 0.079]. One TelaE patient had a partial response and 26 had stable disease (SD). Eleven patients on PboE had SD. Treatment-emergent adverse events included fatigue, anemia, cough, dyspnea, elevated serum creatinine, and diarrhea; grade 3 to 4 events occurred in 74% TelaE patients versus 61% PboE. CONCLUSIONS TelaE was well tolerated and improved PFS versus PboE in patients with mRCC previously treated with TKIs and checkpoint inhibitors.

Abstract
OBJECTIVES The purpose of this study is to provide expert consensus recommendations to establish a global ultrasound curriculum for undergraduate medical students. METHODS 64 multi-disciplinary ultrasound experts from 16 countries, 50 multi-disciplinary ultrasound consultants, and 21 medical students and residents contributed to these recommendations. A modified Delphi consensus method was used that included a systematic literature search, evaluation of the quality of literature by the GRADE system, and the RAND appropriateness method for panel judgment and consensus decisions. The process included four in-person international discussion sessions and two rounds of online voting. RESULTS A total of 332 consensus conference statements in four curricular domains were considered: (1) curricular scope (4 statements), (2) curricular rationale (10 statements), (3) curricular characteristics (14 statements), and (4) curricular content (304 statements). Of these 332 statements, 145 were recommended, 126 were strongly recommended, and 61 were not recommended. Important aspects of an undergraduate ultrasound curriculum identified include curricular integration across the basic and clinical sciences and a competency and entrustable professional activity-based model. The curriculum should form the foundation of a life-long continuum of ultrasound education that prepares students for advanced training and patient care. In addition, the curriculum should complement and support the medical school curriculum as a whole with enhanced understanding of anatomy, physiology, pathophysiological processes and clinical practice without displacing other important undergraduate learning. The content of the curriculum should be appropriate for the medical student level of training, evidence and expert opinion based, and include ongoing collaborative research and development to ensure optimum educational value and patient care. CONCLUSIONS The international consensus conference has provided the first comprehensive document of recommendations for a basic ultrasound curriculum. The document reflects the opinion of a diverse and representative group of international expert ultrasound practitioners, educators, and learners. These recommendations can standardize undergraduate medical student ultrasound education while serving as a basis for additional research in medical education and the application of ultrasound in clinical practice.

Abstract
Abstract
Background
Anastomotic leak (AL) is a common but severe complication after oesophagectomy. It is unknown how to determine the severity of AL objectively at diagnosis. Determining leak severity may guide treatment decisions and improve future research. This study aimed to identify leak-related prognostic factors for mortality, and to develop a Severity of oEsophageal Anastomotic Leak (SEAL) score.
Methods
This international, retrospective cohort study in 71 centres worldwide included patients with AL after oesophagectomy between 2011 and 2019. The primary endpoint was 90-day mortality. Leak-related prognostic factors were identified after adjusting for confounders and were included in multivariable logistic regression to develop the SEAL score. Four classes of leak severity (mild, moderate, severe, and critical) were defined based on the risk of 90-day mortality, and the score was validated internally.
Results
Some 1509 patients with AL were included and the 90-day mortality rate was 11.7 per cent. Twelve leak-related prognostic factors were included in the SEAL score. The score showed good calibration and discrimination (c-index 0.77, 95 per cent c.i. 0.73 to 0.81). Higher classes of leak severity graded by the SEAL score were associated with a significant increase in duration of ICU stay, healing time, Comprehensive Complication Index score, and Esophagectomy Complications Consensus Group classification.
Conclusion
The SEAL score grades leak severity into four classes by combining 12 leak-related predictors and can be used to the assess severity of AL after oesophagectomy.

Abstract
Background Coronavirus disease 2019 (COVID19) caused by the new severe acute respiratory syndrome coronavirus 2 (SARSCoV2) is a global public health emergency. Age and gender are two important factors related to the risk and outcome of various diseases. Cycle threshold (Ct) value is believed to have relation with age and gender. Objective This study has been conducted to investigates the association between SARS-CoV-2 cycle threshold to age and gender of COVID-19 patients, to investigate whether the population-wide change of SARSCoV2 RTPCR Ct value over time is corelated to the number of new COVID19 cases and to investigate the dynamic of RdRp and N genes. Methods 72,811 individuals from second wave of COVID19, were observed in current study at Pure Health Lab, Mafraq Hospital, Abu Dhabi, UAE. Results 15,201/72,811 (21 %) positivity was observed. COVID-19 were more prevalent in males (59.35%) as compared to female (40.65%). The Positivity rate were significantly higher in Male than in Female cases (p-Value = 0.04). The Ct values for both targets of all the samples were ranged from 4.57 to 29.73. Longitudinal analysis showed significant increased during the study period from starting to end as were hypothesized. Interestingly, both the targets (RdRp and N) were present in age < 1 year. Which may indicate that mutated strains are not prevalent in children’s < 1 year. Conclusion There was no statistically significant difference in viral loads in between age-groups. Males were tending to higher viral load compared to females. The findings have implications for preventive strategies.

Introduction
During the early stages of atherosclerosis, monocytes attach to endothelial cells (EC) before differentiating into macrophages causing the accumulation of foam cells and plaque growth. NF-κB and vascular cell adhesion molecule 1 (VCAM-1) are some of the main mediators in EC that are involved in the monocyte adhesion process. Elderberry extract (EE) are rich in anthocyanins a subclass polyphenol with vascular-protective properties.
Purpose
The main of aim of this study is to examine if EE can prevent TNF-α induced inflammation and monocyte adherence to EC.
Methods
Primary Human Umbilical Vein Endothelial Cells (HUVEC) were pre-treated for 1-h and stimulated with or without TNF-α 10 ng/ml for western blot. Cell lysates from the treated cells were then subjected to Western blotting and probed for total and phospho-NF-κB. For monocyte adherence cells were pre-treated for 24-h, then stimulated with/or without TNF-α 10 ng/ml for 24-h. Fluorescently labelled THP-1 cells were then added to the HUVECs for an additional 30 minutes, and samples were measured in a fluorescence plate reader. Cells were put through flow cytometry for measuring reactive oxygen species (ROS) using DCFHFDA assay or VCAM-1 levels using Anti-CD106.
Results
An increase in ROS production and NF-κB phosphorylation was found after stimulation TNF-α 10 ng/ml (p = 0.01). However, cells pre-incubated with EE (50 μg/ml) for 1-hour before TNF-α stimulation caused a reduction in ROS as well as inhibition of NF-κB phosphorylation (p < 0.01). TNF-α 10 ng/ml increased the monocyte adherence to the HUVECs by a 2-fold although, EE prevented TNF-α monocyte adherence (mean value, 589.7 vs 408 p = 0.0033). This was associated with suppressed VCAM-1 expression found in the EE pre-treatment with TNF-α (p = 0.02).
Discussion
Our Preliminary data demonstrates that EE, can prevent monocytes binding onto EC potentially by inhibiting TNF-α induced NF-κB and VCAM-1 levels. Our findings postulate that NF-κB and VCAM-1 could be the direct link for targeting the prevention of monocyte adherence to EC, although this would need confirmation by blocking key cellular signalling pathways to confirm its role. This preliminary data suggests that EE and potentially other polyphenols could be a useful strategy for targeting the initial stages of atherosclerosis.

Abstract
Although photocatalytic technology has emerged as an effective means of alleviating the projected future fuel crisis by converting sunlight directly into chemical energy, no visible-light-driven, low-cost, and highly stable photocatalyst has been developed to date. Due to considerably higher interfacial contact with numerous reactive sites, effective charge transmission and separation ability, and strong redox potentials, the focus has now shifted to 2D/2D heterojunction systems, which have exhibited effective photocatalytic performance. The fundamentals of 2D/2D photocatalysis for different applications and the classification of 2D/2D materials are first explained in this paper, followed by strategies to improve the photocatalytic performance of various 2D/2D heterojunction systems. Following that, current breakthroughs in 2D/2D metal-based and metal-free heterojunction photocatalysts, as well as their applications for H2 evolution via water splitting, CO2 reduction, and N2 fixation, are discussed. Finally, a brief overview of current constraints and predicted results for 2D/2D heterojunction systems is also presented. This paper lays out a strategy for developing efficient 2D/2D heterojunction photocatalysts and sophisticated technology for solar fuel applications in order to address the energy issue.
