Abstract
The list of environmental factors that trigger autoimmune diseases in genetically susceptible individuals has grown in the recent years and is far from complete. The possible intervention of the environment in triggering these diseases is ever more perceived by the clinicians. This study investigated the effect of environmental factors like organochlorine pesticides (OCPs) on proportions of different T lymphocyte subsets and their cytokine secretion in-vitro among pemphigus patients, before and after specific immunosuppressive therapy. Higher levels of OCPs like β-HCH (isoform of hexachlorohexane), α-endosulfan (a form of endosulfan) and p,p΄-DDE (a metabolite of o,p'-dichlorodiphenyltrichloroethane) were observed in the blood of pemphigus patients as compared to healthy controls. HCH and DDT exposure caused specific reduction in CD8+CD45RA+ and CD4+CD25+ T lymphocyte subpopulations in these patient PBMCs. A strong reduction in Th1 (IL-2 and IFN-γ) cytokines upon exposure to these OCPs in-vitro was also observed. These findings indicate that HCH and DDT have a significant impact on Th1 lymphocytes. Impaired production of these cytokines might favor infections and production of autoantibodies. We therefore speculate that the systemic absorption of the pesticide after the topical contact may be one of the factors triggering the immunological mechanism among pemphigus patients.

Abstract
OBJECTIVE This study aimed to assess the appropriateness of direct oral anticoagulants (DOACs) utilization in a Saudi tertiary hospital. PATIENTS AND METHODS Adult inpatients and outpatients diagnosed with atrial fibrillation, deep vein thrombosis, or pulmonary embolism were included in a retrospective cohort study. Patients received at least one month of apixaban, rivaroxaban, or dabigatran. The duration of the study at the Armed Forces Hospital Southern Region in Khamis Mushait, Saudi Arabia, was from January 1, 2019, to December 31, 2021. The study assessed the appropriateness of DOACs dosing, initial and follow-up monitoring, the presence of clinically significant interactions, and treatment duration adherence. RESULTS 778 patients were included in the analysis (mean age 71.34 ± 15.98 years, equal male and female representation). Rivaroxaban was administered to 40.8% of the patients, while apixaban and dabigatran were administered to 31.02% and 28.18% of the patients, respectively. The most prevalent indication for DOACs was atrial fibrillation (72.84%), followed by deep vein thrombosis and pulmonary embolism (27.16%). The most prevalent category of medication errors was inappropriate maintenance dose (41.7%), followed by inappropriate initial dose (37.97%) and lack of laboratory parameter monitoring (36.42%). 31.5 percent of the study sample lacked baseline renal functions, while 24.5% of patients lacked baseline liver functions. 115 patients (14.8%) had potential clinically significant interactions. Regarding treatment duration, 232 patients (29.8%) were improperly prescribed DOACs based on their indications. CONCLUSIONS In a significant proportion of DOAC patients, the prescribed rational DOAC utilization parameters were not implemented. The results of the study provide specific improvement areas and objectives for Anticoagulation stewardship programs.

Abstract
Revolving-disk systems are employed in various industrial settings including turbine engineering, chemical and food processing industries and others. The current article scrutinizes a second-grade fluid motion generated by an infinite porous disk having partial slip character. Heat transfer induced by heating of the disk surface and by viscous and ohmic heating effects is modeled and analyzed under thermal slip condition. Accompanying mass transfer process with thermophoretic diffusion is also formulated. A self-similar system is obtained akin to the case of no-slip case discussed in a previously published study. The adoption of velocity slip assumption induces non-linearity in the boundary conditions in velocity components. Computational procedure embedded in MATLAB bvp4c platform is opted to simulate the system for full range of slip parameters. In contrast to a previously published work pertaining to the no-slip case, present numerical methodology gives accurate results for wide ranges of Prandtl number and elasticity parameter. Boundary layer formations above the disk are examined under various controlling parameters. A comparative assessment of slip and no-slip cases is presented through both graphical illustrations and tabulated results for the resisting torque, the Nusselt number and the Sherwood number. Current numerical findings match very well with the existing homotopy solutions for the no-slip case. The presence of a wall slip mechanism leads to a clear suppression of all the velocity components. Furthermore, an augmentation in the thermal/concentration slip coefficient significantly reduces the thermal/solutal penetration depth. Additionally, we observe a noticeable increase in the driving torque as the elasticity parameter enhances. The slip action of the surface is also predicted to raise the torque required by the disk.

Abstract
Summary A patient treated with intramuscular testosterone replacement therapy for primary hypogonadism developed blurred vision shortly after receiving his testosterone injection. The symptom resolved over subsequent weeks and recurred after his next injection. A diagnosis of central serous chorioretinopathy (CSR) was confirmed following ophthalmology review. A decision was made to change the patient's testosterone regime from this 12-weekly intramuscular injection to a daily topical testosterone gel, given the possibility that peak blood levels of testosterone following intramuscular injection were causing his ocular complaint. His CSR did not recur after this change in treatment. CSR secondary to testosterone therapy is a rare finding but has been reported previously in the literature. Learning Points Blurred vision in patients treated with testosterone replacement therapy (TRT) should prompt an ophthalmology review. The potential for reduced risk of central serous chorioretinopathy (CSR) with daily transdermal testosterone remains a matter of conjecture. CSR is a rare potential side effect of TRT.

Abstract
The purpose of this review was to identify and assess the effectiveness of stem cells in the form of injectables in the treatment of joint osteoarthritis as published in the literature. Studies were searched from multiple databases like Pubmed, Embase and Cochrane Library until June 2022 using multiple keywords. Randomized controlled trials of patients with osteoarthritis (OA) were included which compared the pain and functional outcomes for those getting Mesenchymal Stem Cells (MSCs) injectables as compared to those who received no MSCs injection. Twelve randomized controlled trials, assessing a total of 486 participants were identified and studied. Overall, stem cells injection has no significant effect on pain along with physical function. Stem cells injection could be effective in reducing pain and might also help in improving functional outcome in patients with OA. However, the findings are not yet significant and further clinical trials with larger samples are needed to come to a positive conclusion.

Abstract
OBJECTIVE This systematic review aimed to explore an association of new TR and its quantification in patients undergoing His bundle pacing (HBP). METHODS A literature review was conducted using Mesh terms (His bundle pacing, tricuspid regurgitation, tricuspid valve incompetence, etc.) in PubMed, EMBASE, Web of science CINAHL, and the Cochrane Library till October 2021. Relevant studies evaluating tricuspid regurgitation in HBP were included and information regarding TR and its related factors (ejection fraction (EF) and New York Heart Association (NYHA) class) were retrieved from the eligible studies. RESULTS Out of 196 articles, 10 studies met the inclusion criteria, which consisted of 546 patients with HBP. The mean age of the patients ranged between 61.2 ± 12.3 and 75.1 ± 7.9 years with 54.1% males. The overall implant success rate was 79.2%. Only one study reported a 5% incidence of TR, while 9 studies reported no new TR after HBP. Four studies reported overall decrease in TR by 1 grade and 3 studies demonstrated increased TR from baseline. Two studies showed no change from baseline TR. CONCLUSION HBP causes improvement in TR grade after HBP for cardiac resynchronization therapy (CRT) as well as atrioventricular block (AVB). Further studies in the form of randomized controlled trials are required to further evaluate the effect of HBP on tricuspid valve functioning.

Abstract
Herpes Zoster is a viral infection that occurs due to reactivation of the Varicella Zoster virus. A vaccine has been approved for adults aged 50 and above for the prevention of Herpes Zoster and its complications. This study aims to assess the at-risk population’s awareness of the disease and its vaccine, and attitudes and practices toward the vaccine. A quantitative, observational, cross-sectional study was conducted among 420 adults above the age of 50. Non-probability, convenience sampling was used to select participants from public venues. SPSS-25 was used to analyze the data. 64.3% (n = 270) of participants heard of Herpes Zoster. 78.3% (n = 329) did not recognize the link between chickenpox and Herpes Zoster. Multiple linear regression showed that being female, Arab expatriate, or healthcare professional were the only positive predictors of Herpes Zoster knowledge. 14.8% (n = 62) heard of Herpes Zoster vaccine but 96.7% (n = 406) had not taken it. Participants with chronic diseases were 2.064 times more likely to hear about the vaccine than healthy participants (p = 0.026). Multiple linear regression showed that being a healthcare professional was the only significant predictor of Herpes Zoster vaccine knowledge. 28.1% (n = 118) were not willing to take optional vaccines. Those reluctant to take optional vaccines were 26.023 times more likely to take them if recommended by a healthcare professional (p < 0.001). Attitudes toward Herpes Zoster vaccine were generally positive; however, due to lack of knowledge, poor practices were observed. Nationwide campaigns aimed toward at-risk groups can raise awareness on Herpes Zoster and its vaccine, subsequently improving Herpes Zoster vaccination rate.

Background
The relationship between an acute coronary event and cholesterol levels has been immensely researched, specifically the low-density lipoprotein (LDL) component of cholesterol. According to the Canadian guidelines, LDL cholesterol should be below 1.8 mmol/L if the patient has suffered an acute cardiac event. The European guidelines suggests that LDL target concentration should be below 1.4 mmol/L if the patient has had a previous cardiac event. European guidelines also lowered the LDL recommendations to less than 1 mmol/L if the patient has had 2 previous cardiac event in the previous 2 years.
Purpose
Assess the concordance of one Canadian cardiology clinic to the European LDL guidelines in patients with coronary artery disease.
Methods
Patients were randomly selected from a single centre outpatient Cardiology practice between January and June 2021. All patients were selected by 1 researcher. The patients selected must have been diagnosed with coronary artery disease by Angiography and undergone intervention in the form of percutaneous coronary intervention (PCI) or coronary artery bypass graft (CABG). The blood cholesterol levels were evaluated before and after intervention.
Results
101 patients were randomly selected for this study. Data encompassed 83 males and 18 females ages 43 to 88. Before the intervention, 15 patients had an LDL level below 1.4 mmol/L, 29 patients had an LDL level below 1.8 mmol/L. After the intervention, the number of patients with LDL <1.4 mmol/L was 50 and LDL<1.8 was 85. This population was divided by risk factors and the LDL levels were compared before and after intervention. 9 patients were known to be smokers, their LDL levels were on average 2.73 mmol/L before intervention and 1.3 mmol/L after intervention. 31 patients were known diabetic, their LDL levels were on average 2.15 mmol/L before intervention and 1.43 mmol/L after intervention. 69 patients had hypertension, their LDL levels were 2.36 mmol/L before intervention and 1.46 mmol/L after intervention. Of the 30 patient who had a positive family history, the LDL on average was 2.39 mmol/L before intervention and 1.84 mmol/L after intervention. Positive family history was contingent on having an immediate female relative with age <65 or immediate male relative with age <55 having had a cardiac event or coronary intervention.
Conclusions
The number of individuals on appropriate cholesterol medications after intervention increased thereby reducing the LDL concentration. The data shows that in a sample of the typical Canadian population, 84% of patients were adequately managed after a coronary artery intervention according to the Canadian guidelines. According to the UK guidelines, only 29.5% are being adequately managed. The North American guidelines will likely incorporate the new LDL targets into upcoming revisions and therefore more aggressive risk factor management will be required to meet the new target goals.

Background
The risk of cerebrovascular events has been greatly reduced with the guideline recommendation of anticoagulation in the presence of atrial fibrillation (AF). Based on current epidemiological evidence, over ⅓ of patients with known AF who are eligible for anticoagulation, do not receive them. The elderly population are especially susceptible to this disparity. The CHA2DS2-VASC score is currently being used to assess for need for anticoagulation in patients with AF. More recently, the HAS-BLED score has been developed to assess for bleeding risk. Weighing the bleeding risk using HAS-BLED score with stroke risk using CHA2DS2-VASC score, we assessed if a segment of the Canadian population with AF were appropriately anti-coagulated.
Purpose
Assess the concordance of one outpatient cardiology practice with anticoagulation guidelines for atrial fibrillation.
Materials & Methods
Patients were randomly selected from a single centre outpatient Cardiology practice between January and May 2021. The patients were selected by 1 researcher. The patients selected must have been diagnosed with atrial fibrillation by ECG and Holter analysis. The HAS-BLED and CHA2DS2-VASC scores were calculated for each individual.
Results
101 patients were selected for this study. 66 were male and 35 were female with ages ranging from 33 to 91 years old. Patients with a CHA2DS2-VASC score greater than 1, were anti-coagulated with direct oral anticoagulation (DOAC) unless they were in severe renal failure (creatinine clearance <30ml/min) in which case Warfarin was used. In the age group of 65 and under, 12 patients had a CHA2DS2-VASC score greater than 1 and were anti-coagulated. In the age group 65 and over, 72 had a CHA2DS2-VASC score greater than 1. Of the 72 individuals, 71 were appropriately anti-coagulated. In the age group 80 and over, 29 individuals had a CHA2DS2-VASC score greater than 1 and were anti-coagulated. For the individuals on anticoagulants, the HAS-BLED score was less than or equal to the CHA2DS2-VASC score. Only one of the patients in the study with a CHA2DS2-VASC score greater than 1, was not anti-coagulated. There were no reported major bleeding risks in the patients reviewed.
Conclusion
In a sample of the typical Canadian population, based on risk factor assessments using both the CHA2DS2-VASC and HAS-BLED scores, 99% of patients were appropriately anti-coagulated in the presence of AF. This shows a significant increase in appropriate management of AF patients compared to the current national and global averages. There were no major bleeding events reported in any of the patients receiving full anticoagulation. This supports the recommendation that the benefit of anticoagulation in stroke reduction from thromboembolism outweighs the risk of major bleeding events.

Abstract
Purpose Raynaud’s phenomenon (RP) is defined as frequent ischaemic attacks in the fingers and toes due to vascular vasospasm. Studies have been conducted in many countries worldwide to determine the prevalence of RP. The aim of the current study was to assess the prevalence of RP in the Saudi Arabian population. Patients and Methods An online survey based on international consensus criteria used to diagnose RP was conducted to collect data from individuals from the Saudi population. Participants were considered positive if they had triphasic or biphasic colours of the extremities with cold-related sensitivity. Awareness of RP was also assessed. Results A total of 1025 responses were collected and included in the final analysis. The prevalence of RP was 4.29%, including 22% men and 77% women. The most common age group among women was 26–40 years (36.3%). Familiarity with RP was low, with 56.82% of participants lacking adequate awareness regarding RP. Only 32% of patients with RP reported attending doctor visits regarding symptoms of the disease. Conclusion The RP prevalence in Saudi Arabia is comparable to that reported in the international literature. Public awareness activities should be conducted to increase knowledge about RP. Trial Registration Not applicable.

Abstract
Background The current coronavirus pandemic (COVID-19) was caused by severe acute respiratory syndrome virus 2 (SARS-CoV-2). COVID-19 is characterized by atypical pneumonia, mild colds, and more severe illnesses, such as severe acute respiratory distress, thrombosis, organ failure, and various secondary bacterial and fungal infections. Notably, the severity of COVID-19 in different age groups is not well known, and the validity of clinical laboratory data remains unclear. Methods In this retrospective cross-sectional study, we examined differential regulation of clinical, hematologic, and inflammatory biomarkers in COVID-19 patients. We divided 104 COVID-19 patients into five different groups according to age (0−17, 18−45, 46−65, 66−79, and >80 years). Baseline data (sex, comorbidities, intensive care admission, and medications), hematologic markers, liver, and renal function tests, coagulation, and inflammatory markers were examined in these groups. Receiver operator characteristic (ROC) analysis was used to determine the optimal threshold for predicting COVID-19 biological markers. Results We found that the highest percentage (45%) of COVID-19 patients was in the age group of 46−65 years. The hematologic parameters (WBC, HB, and PLT) were normal between the patient groups. The area under the curve in ROC analysis showed significant differences in the levels of creatine, GGT, BUN, CRP, D-dimer, ferritin, AST, and procalcitonin between the patients of age groups 46−65 and 66−79 years. Renal biomarkers were significantly high in most patients, regardless of age. In contrast, the liver biomarkers, did not differ significantly between patient groups. Conclusion The main finding of our study is that laboratory parameters such as GGT, creatinine, BUN, CRP, procalcitonin, ferritin and D-dimer were differentially regulated in COVID -19 patients of different age groups. Importantly, these laboratory parameters may help as clinical predictors to assess the severity of the disease in the population. We conclude here that age is an important factor influencing COVID-19 severity.

Abstract
Infertility is a serious public health issue affecting around 15% of couples globally. Of the 60-80 million people of reproductive age affected by infertility, 40-50% are due to male factor while 30-40% of cases are still idiopathic. The recent global deterioration in sperm quality raises apprehensions regarding the toxic effects of environmental pollutants on reproductive health of males. Environmental toxicants have shown strong evidences for inducing oxidative stress affecting spermatogenesis severely, thereby leading to reduced sperm motility, count, and DNA damage. Reactive oxygen species (ROS) influences the spermatozoa development and transit process both internally and externally. Low level of ROS is indispensable for critical physiological sperm processes like sperm capacitation, motility, acrosome reaction, hyper-activation, sperm-oocyte interaction, etc., while excessive ROS disrupt antioxidant molecules which is detrimental to normal functioning of the sperm. Hence, identification of potential environmental toxicant may have clinical relevance for early screening and diagnosis of male infertility.

Abstract
Bacteria were isolated from samples of Fresh Apple juices from shops of three different localities of Lahore. Analysis of samples from Liberty, Anarkali and Yateem khana Markets show different levels of contamination. There were pathogenic and non-pathogenic bacteria in all samples and were identified by the morphological and biochemical tests. Most of the plasmids of pathogenic bacteria were 4kb in their molecular size. Ribotyping of 16S ribosomal RNA gene sequencing was done to confirm Helicobacter pylori strain and Gluconobacter oxydans. The highest sensitivity of 210mm was shown by Enterobacter sp. against Aztheromysine disk (15µg) while Micrococcus sp. was highly resistant against all of the Antibiotics applied. The antibiotic resistance of pathogenic bacteria was also checked against Ricinus communis plant's extracts, all isolated bacterial pathogens were resistant but only, E.coli was inhibited at 300µl of the extracts. Presence of pathogenic bacteria in Apple juice samples was due to contamination of sewage water in drinking water while some of these pathogenic bacteria came from Apple's tree and other from store houses of fruits.

Abstract
OBJECTIVE The aim of the study was to determine the expression of cell proliferating marker, anti-proliferating cell nuclear antigen (anti-PCNA) and mesenchymal stem cell (MSC) markers (anti-STRO-1 and anti-CD44) in periapical periodontitis and their role in the healing of periapical lesion in periapical periodontitis. MATERIALS AND METHODS Ninety Sprague-Dawley male rats (100 g) were divided into 3 groups: Experimental group I (EG I: n = 30), experimental group II (EG II: n=30) and control group (CG: n = 30). Periapical lesions were experimentally developed by leaving the dental pulp of maxillary first molars mesial root open to oral environment for 4 weeks. Conventional root canal treatment was performed in EG II. Maxillary first molars along with alveolar bone were resected and fixed. The processed samples were stained with routine hematoxylin and eosin (H&E), and evaluated immunohistochemically using antibodies against anti-PCNA, anti-STRO-1, and anti-CD44 polyclonal antibodies. Data were analyzed using Chi-square test and a p-value of <0.05 was considered significant. RESULTS Immunostaining of anti-PCNA showed 30%, 70% and 53.3% positive staining in CG, EG I, and EG II, respectively (p<0.001). Moreover, the CD44 staining was 20% in CG in contrast to 63.6% in EG I and 43.3 in EG II. STRO-1 staining in CG was 10%, 50% in the EG I and 36.6% in the EG II (p<0.001). CONCLUSIONS Periapical inflammatory tissues expressed significant proliferative cell marker PCNA and mesenchymal stem cell markers STRO-1, and CD44. These findings further reaffirm the promising role of mesenchymal stem cells in the healing of periapical periodontitis.

Abstract
Background The coronavirus disease 2019 (COVID-19) pandemic necessitated widespread changes in delivery of dental care. Telemedicine utilization increased overnight during this pandemic because of its ability to enhance access to oral healthcare, easily link to remote area, time management, low cost, etc. We aimed to identify the utilization of telemedicine among oral medicine practitioners in Saudi Arabia during COVID-19 pandemic and identify future impacts, potential challenges and barriers hindering the implementation of telemedicine. Methods The present cross-sectional electronically self-administered supplement-based survey Supplement Based Survey study was conducted among different professional levels of oral medicine involving consultants, specialists, and residents. The supplement includes demographic data, the current use of telemedicine, participant's perspective on future implications, and potential barriers and limitations of telemedicine. Internal consistency was measured using Cronbach's alpha (α) to assess how closely related a set of items in our study. Results Of the total (N = 75) oral healthcare professionals, 52% were male, 70.7% were Saudi, 45.3% were consultant, 42.7% had 1-5 years of experience, 82.7% were practicing in urban areas, 93.3% stated COVID-19 affected their clinics, consultation was the major reason for the use of telemedicine before (50.7%) and during (72%) COVID-19 outbreak, 57.3% were communicating with their patients, 97.33% had not experienced any cyber risk, and 45% patients were satisfied with the telemedicine service; our data showed a high level of homogeneity (α = 0.82). The poor knowledge and training on telemedicine technologies may substantially (p < 0.05) impact the future implications of telemedicine in oral medicine practice. Conclusion Telemedicine could be a useful adjunct for oral medicine practice, especially for remote diagnosis, consultation, referral, training and education. Our study emphasizes an urgent need to increase the awareness and education on how to utilize and practice telemedicine technologies among medical staff to maximize the efficiency.

Abstract
Abstract
Aims
Meningioma is the commonest primary brain tumour. Despite surgery, meningiomas can recur. Surgery is usually the first line treatment for recurrent meningioma. The aim was to determine the risk factors associated with clinical outcomes (performance status, morbidity, mortality, recurrence) following re-operation for recurrence of intracranial meningioma.
Method
Retrospective cohort study (1998-2018). Eligible patients had re-operation for local recurrence of a previously operated meningioma. Collected data included baseline clinical and imaging characteristic. Primary outcome measure was performance status after each re-operation. Secondary outcome measures were medical and surgical morbidity, recurrence-free survival (RFS) and overall survival (OS).
Results
Fifty-eight patients were eligible (38 female, mean age at 1st re-operation 56 years (SD=11.4)). Eleven patients (18.9%) had 2 re-operations and 3 patients (3.4%) had 3 re-operations. Median follow up was 125.5 months (IQR 73-191.5). Median time to 1st recurrence and 1st re-operation were 36.5 (IQR 24.2–79.1) and 43.8 months (IQR 22.9–102.7), respectively. Fifteen patients (25.9%) had worse performance status after 1st re-operation, compared to 6.9% (n=4) after the primary operation (Figure 1). Complication rate was 32.8% (n=19) after the primary operation compared to 46.6% (n=27) after 1st re-operation. At primary operation, there were 29 (50%) grade 1, 26 (44.8%) grade 2, and 1 (1.7%) grade 3 tumours. Median RFS after first re-operation was 68 months (95% CI 45.5-90.5) (figure 2). Median OS was 312 months (95% CI 236.9-387.1) (Figure 3). Post-operative complications were a risk factor for worsened performance status following re-operation (OR 4.91, 95% CI 1.3-18.4).
Conclusion
Re-operation is associated with a worse performance status and increased risk of complications. Re-operating meningiomas for radiological recurrence without symptoms increases patient morbidity. Shared-care management decision should be made with patients when considering operating for radiological recurrence only.

Abstract
Aims
Bone infiltration in association with intracranial meningioma (4.5% of cases) and primary intraosseous meningioma (2%) are rare. Management can be challenging, as cranial vault reconstruction may be required. This study aimed to examine the surgical techniques used and outcomes in this patient population.
Method
A single-centre, retrospective cohort study was conducted between January 2010 and September 2020. All adult patients who required cranial reconstruction due to bone involvement of their meningioma were included. Patient demographics, tumour characteristics, operative details, complications, and outcomes were examined. Statistical analyses were performed using SPSS v24.0.
Results
There were 30 patients (17 female; 56.7%), median age 54 yrs (range 28-86 yrs), of whom 25 (83.3%) had bone infiltration, and 5 (16.7%) had primary intraosseous meningioma. Only 10 patients had a Simpson I or II resection. Twenty-eight had 'on-table' primary cranioplasties. Materials used were titanium (n=13; 43.3%), acrylic (n=10; 33.3%), PMMA (n=5; 16.7%), and hydroxyapatite (n=2; 6.7%). There were 9 (mostly minor) surgical complications and only one wound infection. Twelve patients had WHO grade II tumours, and 14 required radiotherapy. Ten patients (33.3%) had re-operation for recurrent tumour, with a median time to progression of 41 months. At 6 months, 24 patients had a performance score less than 2.
Conclusion
On-table cranioplasty provides a lower risk surgical option for patients with high risk meningiomas.

Abstract
Objective The aim of this study was to describe the magnetic resonance imaging (MRI) findings and correlate them with the complements level. Methodology This is a retrospective chart review study involving 187 lupus patients attending the rheumatology clinic during the period between 2010 and 2020. Out of the 187 patients, only 49 patients were diagnosed to have neuropsychiatric lupus manifestation and underwent MRI study. Results We included 49 neuropsychiatric systemic lupus erythematosus patients with a mean age of 35.33 years; most of them were Saudi (51%), with disease duration between -six and nine years (40.8%). In regard to MRI brain findings, 51% had abnormal findings, most commonly white matter changes in 42.9% followed by contrast enhancement in 36.7% and mild volume loss in 16.3%. Regarding the complement level, 21 (42.9%) patients had a low C3 level and 35 (71.4%) had a low C4 level. Lastly, following the main objective, C3 and C4 do not have a statistically significant relationship with white matter lesion given the sample of this data (p = 0.589 and p = 0.657, respectively). Conclusion MRI provides a significant clinical information to evaluate neuropsychiatric lupus manifestations. These clinical data can be correlated with immunological findings, which can help in the early diagnosis and management of this disease.

Abstract
Objective The aim of this study was to investigate the potential relationship between the volumetric area of the upper airway and rheumatoid arthritis (RA) by comparing upper airway measurements between patients with and without RA. Methods This case-control study compared upper airway measurements between patients with and without RA using lateral cephalometric radiographs. Two distinct measurements were made: the area of the upper airway, which is defined as "the area extending from the point of the retro-palatal region to the base of the epiglottis," and the distance of the upper airway, which is defined as "the distance between the anterior border of the third cervical vertebra (C3) and the anterior border of the soft tissue of the neck". A single examiner performed all measurements, and the intra-examiner reliability was assessed. Results Sixty-one RA patients and 95 non-RA patients were included in the case and control groups, respectively. RA patients were significantly older in age and with higher BMI values. Patients with or without RA had Angle Class II as the most prevalent orthodontic classification. The upper airway was slightly narrower in RA patients, resulting in a smaller area, and the length of the upper airway was significantly longer in RA patients. Conclusion Patients with RA have narrower upper airways as measured on lateral cephalometric radiographs. This may partially explain the high prevalence of obstructive sleep apnea among patients with RA. Focusing on airways measurements when cephalometric radiographs are taken for patients with RA could give some idea about which patient is likely to have OSA.

Abstract
Implant reconstruction following scapulectomy in children is a challenging task. Dual suspension reconstruction may offer an alternative but there is a dearth of literature on functional outcomes following this procedure for malignant tumours in children. A retrospective study was conducted at the Aga Khan University Hospital, a tertiary care centre in Karachi, Pakistan. Children with malignant tumours of the scapula who underwent total scapulectomy with dual suspension reconstruction (n=5) between Jan 2009 and June 2015 were included. Mean follow up was 50±13.39 months. There were four boys and one girl having mean age of 11±3.57 years. All patients were Enneking Stage IIB with 4 patients diagnosed as Ewing's Sarcoma and 1 as osteosarcoma. The MSTS scores ranged from 20-25 points, with a median of 23. One patient developed postoperative surgical site infection requiring surgical debridement whereas all patients remained disease-free till last follow up. Our findings suggest that scapulectomy with dual suspension reconstruction achieves satisfactory functional results with low rate of complications.

Abstract
The aim of this study is to describe the management and outcome of surgical treatment for post burn contractures in different parts of the upper extremities in children, and provide a final decision algorithm that can be a useful guide for the Resident regarding surgical approach to contracture management. This was a retrospective study conducted in the Clinic of Plastic and Reconstructive Surgery, Pristina-Kosovo, between 2014-2016. All cases continued check ups in the Gentiana-Grelor private clinic in Pristina until 2019. Followups were conducted for no less than 6 months with respect to the viability and healing of the repaired area. Patients of both genders, aged from 0 months to 18 years with post-burn contracture in upper extremity, were included in the study. For the sake of presentation, we divided them anatomically into four main areas: axilla, elbow, wrist and hand. We start with a reconstructive ladder using skin grafts (STSG, FTSG), and local flaps such as advancement flaps, Z-plasties, V-Y or Y-V advancement flap, abdonimal/groin pedicled flap, cross finger flap, radial forearm flap were used. Patients were called for follow-up lasting a minimum of one to up to three years. The study included 144 patients. Their age ranged from 9 months to 18 years, the mean age being 12 years. Ordering them by location, post-burn contracture percentage in upper extremity in children was 68% on the hands, 18% on the elbows, 8% on the axilla and 6% on the wrist. A classification and treatment algorithm aids in achieving significant improvements in both joint motions and aesthetic deformities.

Abstract
Background Routine preoperative tests in healthy patients not only cause extra anxiety, but may delay treatment without influencing surgical plan. This has worse impact in resource-constrained settings where fee for service rather than health insurance is the usual norm. Investigators aim to determine if “routine” pre-operative tests are justified in healthy orthopedic patients. Methods We conducted a non-commercialized, non-funded matched case control study in tertiary care university hospital and a level-1 trauma centre for healthy patients (ASA-1&2) admitted from January 2014–December 2016 for elective orthopedic intermediate and major procedures. Cases (patient who had a change in his/her surgical plan after admission) and controls were selected independently of the exposure of interest then matched randomly to cases on age, gender and procedure type. Primary exposure was the routine preoperative lab tests, as defined by the American Society of Anesthesiologist, which included 13 blood tests. Analysis was done using Principle Component Analysis and Conditional logistic regression at univariate and multivariable levels reporting matched adjusted Odds Ratios. The data was reported in line with STROCSS criteria. Results Overall, 7610 preoperative tests were done for 670 patients with 62% men among cases and 53% men among controls with mean age of 49.9±22.5 years and 41.1±23.0 years, respectively. There were 1076 (14%) abnormal result that influenced surgical plan in 0.96% cases only. Matched adjusted OR with 95% confidence interval of primary exposure was insignificant. Conclusion Routine preoperative tests were superfluous and did not influence the surgical plan when adjusted for other variables in the model as well as after matching on potential confounders. This study would be amongst first steps to move towards an evidence based surgical practice for preoperative evaluation. The “routine” pre-operative tests in healthy orthopaedic patients undergoing intermediate/major surgery are not justified. Surgical plan was influenced in <1% of ASA-I & ASA-II elective orthopedic patients. Blood tests were not associated with change in surgical plan. Surgeons should be sensitized to reconsider this practice particularly with limited resources.

Abstract
Background Over the last century, there has been a remarkable development in the study of bone and soft tissue sarcomas. This is primarily due to the improved knowledge of the nature of these lesions and the improved imaging technology. In literature there are many protocols that are being used and all of them have reported various advantages and disadvantages of each technique used. However, there is no set guideline and whatever has been proposed has been developed on the basis of the experience of different centres and different surgeons. OBJECTIVE The current systematic review was planned to thoroughly evaluate the levels of evidence on which we base decisions for surgical management of lower extremity bone tumours. METHODS The review included descriptive studies published in the English language. Studies included case reports, case series and experiences of different centres for the surgical management of lower extremity bone tumours. Articles reporting all levels of evidence - Level I to V - were included. PubMed, ERIC, MEDLINE, EMBASE and Cochrane Reviews databases from 2002 to 2012 were searched. RESULTS Information was gathered and thoroughly studied from 63 articles. There were no Level I studies, 2(3.2%) Level II studies, 47(74.6%) Level III, and the remaining 14(22.2%) studies were Level IV and Level V. CONCLUSIONS Sarcomas are rarely occurring neoplastic conditions which are present in all age groups but commonly affect young age population. Most are asymptomatic but can present with pain or pathological fracture. These lesions are commonly diagnosed with plain radiographs. CT scan and MRI may be used to delineate anatomy and to quantify the extent of soft tissue involvement. Various advantages and disadvantages associated with each aspect in the management of patients starting from the basic history-taking, physical examination, imaging, biopsy principles, peri-operative laboratory work-up and staging of the cancer were studied. Treatment ranges from conservative to en-block resection including extended curettage. Aggressive tumours should be closely followed up for recurrence and metastasis.

Abstract
Background Endodontic treatment failure is one of the most common problems encountered in dentistry. Aims This study aimed to evaluate the causes of failure of endodontic treatment among patients in the Saudi Arabian city of Al-Kharj. Subjects and Methods A total of 250 patients of both genders were involved in the study. Criteria confirming the failure of the endodontic treatment were pain, tenderness on pressure, periapical radiolucency, and sinus tract. Patients were selected by convenience sampling methods. A diagnostic chart was prepared to complete the investigation in three different hospitals, during a six-month period (October 2018 - March 2019). The results were analyzed statistically using Chi-square test and use of simple arithmetical methods to determine percentage and frequencies. Results The main cause for endodontic failure was poor quality adjunctive treatment. 147 out of 179 male patients and 53 out of 71 female patients received poor quality treatment. There was a statistically significant difference between gender versus adjunctive treatment (P = 0.009) and between hospital versus adjunctive treatment (P = 0.005), and quality of adjunctive treatment between private hospital as compared to government hospital which was also statistically significant (P = 0.008). In quadrant wise distribution, first molars were the most commonly involved teeth. Inadequate filling of the root canal was (36.8%), missed canals (14.4), over-extension root canal fillings (12.8%), perforations (9.6%), instrumentation related (8.8%), and endodontic access preparation related (2.4%) in the decreasing order of frequency were seen as the most common causes of failure of endodontic treatment. Conclusion First molars were the most commonly affected tooth in the failure of endodontic treatment. Poor adjunctive treatment and inadequate filling of the root canals were the most common causes of endodontic failure, more commonly seen in male than female patients and in private clinics/hospitals than government hospitals.

Abstract
Machine learning (ML) provides novel and powerful ways of accurately and efficiently recognizing complex patterns, emulating nonlinear dynamics, and predicting the spatio-temporal evolution of weather and climate processes. Off-the-shelf ML models, however, do not necessarily obey the fundamental governing laws of physical systems, nor do they generalize well to scenarios on which they have not been trained. We survey systematic approaches to incorporating physics and domain knowledge into ML models and distill these approaches into broad categories. Through 10 case studies, we show how these approaches have been used successfully for emulating, downscaling, and forecasting weather and climate processes. The accomplishments of these studies include greater physical consistency, reduced training time, improved data efficiency, and better generalization. Finally, we synthesize the lessons learned and identify scientific, diagnostic, computational, and resource challenges for developing truly robust and reliable physics-informed ML models for weather and climate processes. This article is part of the theme issue 'Machine learning for weather and climate modelling'.

Abstract
Von Kármán problem of infinite disk is re-examined when fluid under consideration is elastico-viscous, satisfying the constitutive relations of Walters-B model. Main target here is to demonstrate how the presence of elasticity alters heat transfer phenomenon for the said problem especially when heat dissipation term is included in the analysis. We assume a self-similarity solution that results in a system of coupled non-linear equations. An easy to use package BVPh 2.0 based on the homotopy analysis method is used to present series solutions for values of elastico-viscous fluid parameter (\documentclass[12pt]{minimal}

Abstract
BACKGROUND Gestational diabetes mellitus (GDM) is associated+ with adverse pregnancy outcomes compared with women with normal glucose tolerance in pregnancy. The WHO recommends screening at 24-28 weeks gestation for GDM. Women who are diagnosed before 24-28 weeks gestation have a longer intervention period which may impact positively on pregnancy outcomes. AIM This study aimed to examine pregnancy outcomes of women with GDM diagnosed <24 weeks gestation compared with those diagnosed at 24-28 weeks in a large Irish cohort. METHODS A retrospective cohort study of 1471 pregnancies in women with GDM diagnosed using IADPSG criteria between September 2012 and April 2016 was conducted. At GDM diagnosis, women were classified as early GDM <24 weeks or standard GDM 24-28 weeks gestation. RESULTS Women with early GDM had a significantly greater risk of pregnancy-induced hypertension (12.4% vs. 5.3%; P < 0.05), post-partum haemorrhage (8.7% vs. 2.4%; P < 0.05) and post-partum glucose abnormalities (32% vs. 15.6%; P < 0.05). Their offspring had a greater risk of pre-maturity (10.9% vs. 6.6%; P < 0.05), stillbirth (1.4% vs. 0.5%; P < 0.05), large for gestational age (19.1% vs. 13.4% P < 0.05) and need neonatal intensive care (30.7% vs. 22.1%; P < 0.05) compared with offspring of women with standard GDM. Rates of C-section and pre-maturity were still higher in the early GDM group when the two groups where compared based on their post-natal OGTT. CONCLUSION Early GDM women and their offspring are at greater risk of an adverse pregnancy outcome compared with those diagnosed at 24-28 weeks. In view of the abnormal post-natal glucose findings, early GDM may reflect a more advanced state in diabetes pathogenesis.

Abstract
BACKGROUND Undergraduate (UG) research is new but important concept in modern science. It is considered as an effective educational tool for enhancing the undergraduate medical experience. The objectives of the study were to know the perceptions of UG medical students towards research, main motivating factors and barriers faced by the students. METHODS It was Crosssectional study with both quantitative and qualitative portions conducted in Ayub Medical College (AMC) from November 2018 to April 2019. The quantitative portion of the study was based on a simple questionnaire with 9 closed ended questions completed by 215 participants selected using stratified random sampling technique. Data was analysed using SPSS 20.0. The Qualitative portion of the study was based on 8 Focused Group Discussions (FGDs), two from each year, with 6-10 participants. The interviews were recorded and reported by obtaining informed consent from each participant. The audio recording of the FGDs was transcribed verbatim and content analysis was done by conventional content analysis. RESULTS Out of 215, 128 (59.5%) had a previous research experience mostly as a compulsory requirement of undergraduate curriculum; 134 (62.3%) were aware that research is a part of their curriculum. Lack of resources and lack of interest of students was main barrier, i.e., 152 (70.7%). For 133 (61.8%) participants, the main motivating factor was learning research methodology. CONCLUSIONS Students were aware about research and their awareness about research increased with increasing year in medical school. Hardly any student had a research experience beforehand they took part in mandatory research in 4th year.

Abstract
Objective The purpose of this study was to determine the amount of bone available for harvesting from the anterior palate region using IOPA (Intra Oral Peri Apical) radiographs. Materials and Methods A total of 80 patients visiting the outpatient Department of Periodontics were selected. Two groups of male and female consisting 40 patients each were made. They were further subdivided into two groups based on age, 18-30 and 31-60 years of age, each with twenty patients. The patients were subjected to radiographic examination consisting of IOPA radiographs. All IOPA radiographs were taken using long cone paralleling technique. Availability of bone for harvesting, above the apices of teeth was calculated. Results The bone available in the incisor region was approximately 6.5 to 6.9 mm in height and 7.4 to 8 mm in width, in canine region 6.35 to 6.65 mm in height and 7.6 to 8.1 mm width, and in the premolar region 3.65 to 3.75 mm in height and width. When the bone height and width were compared gender and age wise for CI (central incisors), LI (lateral incisors), canine and premolars, using Student's t- test the results were not statistically significant. Conclusion For the purpose of harvesting autogenous bone, from the region of incisor and canine approximately 6.35 to 6.9 mm height and 7.4 to 8.1 mm width of bone may be harvested maintaining a safe distance from the apices of the teeth and the nasal floor. The premolar region does appear to yield sufficient bone at safe distances from the maxillary sinus and the apices of the premolars.

Abstract
Nutrilabelapps© is an interactive augmented reality mobile application (app) providing
nutrition menu labelling specifically built for Mutiara Café, a café in Universiti Malaysia
Terengganu. However, no evaluation of the usage of Nutrilabelapps© has been carried
out. Therefore, this cross-sectional study was aimed to determine the knowledge and
attitude of nutrition menu labelling among Mutiara Café customers; the feasibility and
acceptability of the app among customers; and also, the relationships between knowledge,
attitude, feasibility and acceptability of this augmented reality nutrition menu labelling
app. This study was conducted among 108 Mutiara Café customers who owned a
smartphone and were able to download the Nutrilabelapps©. The data were analyzed
using SPSS version 25. Findings showed that only 4.6% of Mutiara Café customers had
good knowledge of nutrition menu labelling, while 71.3% of them had a positive attitude
towards nutrition menu labelling. Nutrilabelapps© was accepted by users based on the
feasibility (67.6%) and acceptability (75.9%) of the app. Remarkably, there was a
significant association between knowledge, attitude, feasibility, and acceptability of the
app at p < 0.05. As a conclusion, Nutrilabelapps© is highly recommended among the café
customer despite their low knowledge of the nutrition menu labelling. Therefore, more
education of the public about nutrition menu labelling is highly recommended

Abstract
HSP27, also known as HSPB1, was first discovered with a molecular weight 27kDa belonging to the four member gene family. Elevated levels of HSP27 are seen when different unfavorable conditions prevail such as increase in temperature and oxidative stress or exposure to heavy metals or organic solvents. They possess ATP-independent chaperone like activity which helps in maintaining protein homeostasis. It can also form large oligomers (300-600 kDa) containing different numbers of subunits. It is composed of total 205 amino acids. HSP27 undergoes post-translational modifications i.e. phosphorylation thereby converting large oligomers into dimers. It can act as an anti-apoptotic and antioxidant molecule during oxidative stress. The elevated form of HSP27 is also seen in some cancer belongs to breast, ovary, prostate, brain, colorectal, hepatocellular carcinoma, lung, liver, and cervical regions. Keeping in view of molecular roles of HSP27 signaling in various pathways, we have proposed their translational values in different diseases. In addition, we have also reported the existing scientific data on the HSP27 as the potential cancer biomarker and their therapeutic targets for improved prognosis and treatment in different diseases.

Abstract
Systemic lupus erythematosus (SLE) is a multisystem autoimmune disease. Although gastrointestinal (GI) involvement is reported in the literature, GI manifestations of lupus are not common in the early disease course. GI symptoms can be related to several factors other than lupus; however, systemic lupus per se can be the responsible factor. Although the typical presentation is a gradual onset of progressive symptoms, acute abdominal pain is frequently reported and is the most serious presentation. It can reflect gastroenteritis, cholecystitis, hepatitis, pancreatitis, peritonitis, and abdominal vasculitis. When SLE diagnostic criteria for GI manifestations are lacking, the decision to implicate lupus as the cause of these manifestations is difficult, especially in the primary presentation. Early diagnosis and the initiation of immunosuppressive agents are associated with a better outcome. In this case, we introduce a patient who presented with acute abdominal pain secondary to acute liver failure as the first manifestation of lupus.

Abstract
Background Behcet’s disease (BD) is a complex, inflammatory, immune-mediated multi-systemic disease of unknown etiology. Cytokines play major roles in the pathophysiology of BD, and its production may be affected by polymorphism in cytokine genes. Hence, the present study was planned to investigate any possible association between the polymorphism in TGF-β, IFN-γ, and IL-6 genes and BD in the Saudi population. Materials and Methods The present study includes 79 BD cases and 117 age-matched controls. Polymerase chain reaction with restriction fragment length polymorphism (PCR-RFLP) and amplification refractory mutation systems (ARMS) PCR methods were used for polymorphic analysis. Results The heterozygous (CT) and (CT+TT) combined genotypes of TGF-β (509-C/T), heterozygous (AT), variant (TT), and (AT+TT) combined genotypes of IFN-γ (874-A/T) were significantly (P<0.05) associated with BD in the Saudi population. No significant differences were observed for IL-6 (174-G/C) genotypes and alleles between BD cases and controls. Gender does not reflect any significant genotypic and allelic association with males and females. Conclusion CT genotype of TGF-β, and AT and TT genotypes of IFN-γ could be associative genetic risk factors for BD in Saudis. Regulatory region polymorphism in cytokines gene can increase inflammation and deregulated immune response, which could be risk factor for BD.

Abstract
STUDY OBJECTIVES Although previous studies suggested an increased prevalence of obstructive sleep apnea (OSA) among patients with rheumatoid arthritis (RA), no existing large prospective study has addressed this association using objective measures. This study aims to assess the prevalence of OSA using polysomnography (PSG) in patients with RA and its relationship with RA activity. METHODS Patients with RA who presented at the rheumatology clinic at a university hospital from 2017 to 2018 were eligible. In the first stage, data from the Disease Activity Score 28, Berlin questionnaire, and Epworth Sleepiness Scale were obtained, along with personal data and a comprehensive medical history. The second stage involved a case-control study confirming OSA with PSG. OSA was defined as an apnea-hypopnea index (AHI) ≥ 5 events/h, whereas patients with an AHI ≥ 15 events/h were categorized as having moderate-severe OSA. RESULTS In total, 199 patients with RA were recruited, 110 patients (55%) underwent PSG, and 5 were excluded. The mean age was 48.93 ± 12.7 years, and the mean body mass index was 31.70 ± 9.74 kg/m²; 94% were female. In total, 67 participants (33.2%) were at high risk for OSA (36 [55.4%] underwent PSG), whereas 132 (66.8%) were at low risk (69 [51.5%] underwent PSG). The estimated prevalence of OSA (AHI ≥ 5 events/h) in the whole population was 58.1%, whereas the prevalence of moderate-to-severe OSA (AHI ≥ 15) was 22.9%. CONCLUSIONS This prospective PSG-based study demonstrated that OSA is more common in patients with RA than in the general population, but there appears to be no relationship with disease activity.

Abstract
Introduction GCT is a benign primary bone tumor which is known to cause local recurrence as well as distant metastases. The standard care of treatment of GCT in our institution is the extended intralesional curettage followed by the use bone cement and either phenol or alcohol as adjunct therapy. This offers preservation of joint closest to tumor and decreased risk of recurrence compared to curettage alone. Therefore, the objective of this study was to assess the recurrence of GCT of the bone and time of recurrence-free survival after primary surgery (curettage with adjunct therapy) and determine the influence of factors like site of tumor involvement and demographic factors on the risk of recurrence. Methods Non-funded, non-commercial single group retrospective cohort study was conducted at a tertiary care university hospital. Total of 44 patients treated for primary GCT of the bone between 1995 and 2015 at our institution were included. Medical record files were reviewed for demographic characteristics, intra-operative findings and post-operative follow-up. Risk factors for recurrence and mean recurrence free survival was calculated using appropriate statistical analysis. Results Proximal tibia was the most commonly involved bone followed by distal femur, while intralesional curettage with either phenol or alcohol as adjunct was the most common primary treatment. Mean follow-up period for all patients was 52.1 ± 43.9 months. Out of the 46 tumors operated primarily at our institution, recurrence developed in eight (17.4%) cases. Extra-compartmental spread of tumor and tumor grade were identified to have a significant association with recurrence (P = 0.013 and 0.043 respectively). Estimated recurrence free survival at 2 and 5 - year interval was 0.85 and 0.83 respectively. Conclusion Extra-compartmental extension of tumor and a higher-grade lesion is significantly associated with development of recurrence in cases of GCT of bone.
