Abstract
Gallic acid (GA) is a naturally occurring polyphenol with a strong antioxidant capacity. GA stimulates the apoptosis of cancer cells, thereby suppressing cancer cell invasion. However, the low oral permeability of GA limits its therapeutic use. In order to enhance the antioxidant capacity and oral permeability of GA, a series of compounds analogous to GA were synthesized: 4-methoxybenzenesulfonamide (MBS), 3,4-dimethoxybenzenesulfonamide (DMBS) and 3,4,5-trimethoxybenzenesulfonamide (TMBS). In the new compounds, hydroxyl groups were replaced with various numbers of methoxy groups (stronger electron-donating groups), to increase hydrophobicity and oral permeability compared to GA. In addition, the carboxylic group was replaced with a sulfonyl group (a stronger electron-withdrawing group), to increase the molecular polarity and antioxidative activities of the compounds. The cell counting kit-8 (CCK-8) assay was used to detect the effect of GA, MBS, DMBS, and TMBS on cell proliferation and apoptosis in peripheral blood mononuclear cells (PBMCs) from healthy individuals and non-small cell lung carcinoma A549 cells. Additionally, the comet assay was used to assess the genotoxicity of these compounds in PBMCs from healthy individuals, lung cancer patients, and A549 cells. Compared to untreated cells, TMBS reduced DNA damage more effectively than GA in PBMCs from lung cancer patients and healthy donors. Furthermore, in comparison to GA, TMBS was more cytotoxic in A549 cells. Moreover, TMBS was not cytotoxic in healthy PBMCs, suggesting that TMBS demonstrates therapeutic potential in cancer.

Abstract
INTRODUCTION Allergic rhinitis (AR) is an inflammatory disease of the nasal mucosa. It is among the most common diseases globally and usually persists throughout life. Allergic Rhinitis and Its Impact on Asthma (ARIA) is a wellestablished guideline applicable to AR and was updated regularly since 2001, aiming to improve the care for AR patients. We proposed a new questionnaire that addresses the severity of allergic rhinitis symptoms, specifically nasal symptoms, and its impact on quality of life in terms of specific vital activities such as sleeping, working, school performance, leisure, or sport, based on the ARIA guideline. The objective was to develop, validate and evaluate Allergic Rhinitis Symptoms and Impact Assessment (ARSIA) questionnaire among allergic rhinitis patients in Hospital Sultan Abdul Halim, Sungai Petani (HSAH), and Hospital Universiti Sains Malaysia (HUSM). MATERIALS AND METHODS This is a prospective observational study to develop, validate and evaluate the ARSIA questionnaire based on ARIA guidelines. The sample will be obtained from the list of patients under follow-up in the ORL clinic HSAH and HUSM with ages of 18 to 60 years, patients clinically diagnosed with allergic rhinitis, and with positive skin prick test. RESULTS A total of 150 patients with a positive skin prick test participated in this study. In the 'nasal symptom' and 'impact on daily activities' domains, calculated Cronbach's alpha shows a value of 0.878 and 0.811 respectively. The inter-item correlation was calculated to analyse internal consistency reliability. Items B3 and B4 were dropped from the questionnaire as both showed a low correlation with other items. New Cronbach's alpha for the daily activities domain was 0.830, which showed better internal consistency reliability. All of the items were analysed for sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV). Clinician diagnosis from the proforma was used as a comparison to the participant's responses. In the analysis, a cut-off points of 12 was used to classify the patient's nasal symptoms into intermittent or persistent, with a sensitivity of 75%, specificity of 86%, PPV of 95%, and NPV of 51%. Whereas, a cut-off point of 15 was used to classify the rhinitis impact on daily activities into mild or moderate/severe, with a sensitivity of 58%, specificity of 100%, PPV of 100%, and NPV of 42%. The only item in the 'control' domain has been dropped out following a consensus of experts and judgement as it has not been used in the clinician diagnosis and thus, is unable to test for sensitivity, specificity, PPV, and NPV. CONCLUSION This newly developed, validated, and evaluated questionnaire is a good tool for the evaluation of allergic rhinitis symptoms and their impact on daily activities. It is important to understand that AR symptoms could have a significant impact on daily activities. Although further study and testing are needed, it provides an initial means for evaluating the patient condition and control level, as well as patients' perception of their rhinitis control.

Abstract
PURPOSE We report a case of unilateral Terrien's marginal degeneration in a 14-year-old girl. CLINICAL CASE Slit-lamp examination of the affected eye revealed 360° circumferential lipid deposits with 6mm of superior limbal distension, superficial neovascularization, a zone of corneal thinning from 3:00 to 9:00 with a zone of corneomalacia at 11:00. The remainder of the cornea was clear, without fluorescein staining or anterior chamber reaction. DISCUSSION Terrien's marginal degeneration (TMD) is typically known to occur bilaterally in men over the age of 40. Terrien's degeneration must be differentiated from other causes of peripheral corneal thinning; the primary differential diagnosis is Fuchs' marginal keratitis. Other causes of corneal thinning must be ruled out, including Mooren's ulcer. In Terrien's degeneration, there is no central mined edge in the thinning sulcus, the epithelium remains intact, and affected patients do not present with pain. Other differential diagnoses include pellucid marginal degeneration and sulcus degeneration, which are characterized by the absence of lipid infiltrates associated with the central region of the thinning zone, thus distinguishing them from TMD. CONCLUSION It is important to keep in mind that Terrien's marginal degeneration can occur in children.

Abstract
Congenital ectropion uveae (CEU) is a rare anomaly of the embryonic development of the anterior segment of the eye. We report the case of a 5-year-old child with an undiagnosed CEU who was treated urgently for an acute angle closure attack. CASE DESCRIPTION A 5-year-old child was referred urgently for evaluation of anisocoria with mydriasis of the right eye and severe headache. Brain imaging with contrast injection was initially performed in the pediatric emergency department and ruled out central nervous system pathology. The initial examination of the right eye revealed an intraocular pressure (IOP) of 37mmHg, corneal edema, congenital ectropion uveae, mydriasis with pupillary block, a closed angle on gonioscopy, and a clear lens. The examination of the left eye was unremarkable, with no visible CEU. The initial management consisted of medical treatment with topical glaucoma drops and miotics and acetazolamide at 10mg/kg/d. Re-evaluation under general anesthesia showed persistent mydriasis and no resolution of the pupillary block. Filtering surgery was performed in the absence of a complete response to medical treatment, allowing control of IOP without drops and complete regression of the corneal edema. DISCUSSION CEU is a rare malformation, and pressure complications represent an insignificant proportion of pediatric glaucoma cases. The acute presentation of acute angle closure in this potentially blinding short-term setting, however, makes detection and management difficult in very young children in a great deal of pain. Only one similar case has been reported in the pediatric literature. CONCLUSION Acute angle closure complicating CEU is exceptional and difficult to diagnose in a pediatric context. Parents of children with this predisposing condition should be informed of the need to consult urgently when clinical signs of elevated intraocular pressure appear.

Abstract
Background Standardized methods for reporting surgical quality have been described for all the major urological procedures apart from radical nephroureterectomy (RNU). Objective To propose a tetrafecta criterion for assessing the quality of RNU based on a consensus panel within the Young Association of Urology (YAU) Urothelial Group, and to test the impact of this tetrafecta in a multicenter, large contemporary cohort of patients treated with RNU for upper tract urothelial carcinoma (UTUC). Design, setting, and participants This was a retrospective analysis of 1765 patients with UTUC treated between 2000 and 2021. Outcome measurements and statistical analysis We interviewed the YAU Urothelial Group to propose and score a list of items to be included in the “RNU-fecta.” A ranking was generated for the criteria with the highest sum score. These criteria were applied to a large multicenter cohort of patients. Kaplan-Meier curves were built to evaluate differences in overall survival (OS) rates between groups, and a multivariable logistic regression model was used to find the predictors of achieving the RNU tetrafecta. Results and limitations The criteria with the highest score included three surgical items such as negative soft tissue surgical margins, bladder cuff excision, lymph node dissection according to guideline recommendations, and one oncological item defined by the absence of any recurrence in ≤12 mo. These items formed the RNU tetrafecta. Within a median follow-up of 30 mo, 52.6% of patients achieved the RNU tetrafecta. The 5-yr OS rates were significantly higher for patients achieving tetrafecta than for their counterparts (76% vs 51%). Younger age, lower body mass index, and robotic approach were found to be independent predictors of tetrafecta achievement. Conversely, a higher Eastern Cooperative Oncology Group score, higher clinical stage, and bladder cancer history were inversely associated with tetrafecta. Conclusions Herein, we present a “tetrafecta” composite endpoint that may serve as a potential tool to assess the overall quality of the RNU procedure. Pending external validation, this tool could allow a comparison between surgical series and may be useful for assessing the learning curve of the procedure as well as for evaluating the impact of new technologies in the field. Patient summary In this study, a tetrafecta criterion was developed for assessing the surgical quality of radical nephroureterectomy in patients with upper tract urothelial carcinoma. Patients who achieved tetrafecta had higher 5-yr overall survival rates than those who did not.

Abstract
In-situ bioremediation of mangrove soil contaminated with polyethylene terephthalate (PET) and polystyrene (PS) microplastics was investigated using indigenous microbial consortium with adequate capacity to degrade the plastics. Eight (8) bacteria were isolated from plastic/microplastic-inundated mangrove soil and screened for the ability to degrade PET and PS microplastics. Optical density at 600 nm and colony forming unit counts were measured to evaluate the growth response of the microbes in the presence of PS and PET microplastics at different times of exposure. Structural and surface changes that occurred post biodegradation on the microplastics were determined through EDS and SEM analysis. The obtained results demonstrated the elongation and disappearance of peaks, suggesting that the microbial consortium could modify both types of microplastics. The overall results of the microplastic degradation showed varied degrees of weight loss after 90 experimental days, with the treated plot recorded 18% weight loss. The augmented soil was increased in the concentrations of Si S, and Fe and decreased in the concentrations of C, O, Na, Mg, Al, Cl, and K after bioremediation.

Abstract
Diabetes mellitus (DM), an endocrine syndrome characterized by high blood glucose levels due to abrogated insulin activity. The existing treatments for DM have side effects and varying degrees of efficacy. Therefore, it is paramount that novel approaches be developed to enhance the management of DM. Therapeutic plants have been accredited as having comparatively high efficacy with fewer adverse effects. The current study aims to elucidate the phytochemical profile, anti-hyperlipidemic, and anti-diabetic effects of methanolic extract D. salicifolia (leaves) in Alloxan-induced diabetic mice. Alloxan was injected intraperitoneally (150 mg kg-1, b.w), to induced diabetes in mice. The mice were divided into three groups (n=10). Group 1 (normal control) received normal food and purified water, Group II (diabetic control) received regular feed and clean water and group III (diabetic treated) received a methanolic extract of the plant (300 mg kg-1) for 28 days with a typical diet and clean water throughout the experiment. Blood samples were collected to checked serum glucose and concentration of LDL, TC, TG. The extract demonstrated significant antihyperglycemic activity (P<0.05), whereas improvements in mice's body weight and lipid profiles were observed after treatment with the extract. This study establishes that the extract has high efficacy with comparatively less toxicity that can be used for DM management.

Abstract
Lichenoid uvula mass is an unusual entity and the clinicopathologic entities are important for the diagnosis. In this case report, we report an elderly lady presented with dysphagia and "hot potato voice" due to a lichenoid uvula mass. Apart from muffled voice, the other associated symptoms are dysphagia, sore throat, globus pharyngeus and snoring. She was a non-smoker, and not on any medications except for hypertension and dyslipidaemia. Apart from the enlarged uvula, other parts of the oral cavity, oropharynx and larynx were normal. She has no other signs such as cutaneous lesions. The mass was excised under general anaesthesia followed by resolution of symptoms. Awareness of this entity, the clinical and histopathological features should be highlighted to differentiate it from other diagnosis.

Abstract
Abstract
Background
Coronary vascular dysfunction is a common cause of symptoms in patients with angina and no obstructed coronary arteries (ANOCA). Several endotypes have been defined but there are big gaps in our understanding of the underlying pathophysiology. Proteomic analyses may improve the understanding of the pathophysiology.
Purpose
Exploratory approach to 1) compare the proteomic biomarker profile across different types of vascular dysfunction in ANOCA and 2) assess the value of prediction models with protein biomarkers for vascular dysfunction in ANOCA.
Methods
We included 107 angina patients without previous coronary artery disease, left ventricular ejection fraction >45% and no obstructive coronary artery disease (CAD) (<50% stenosis of epicardial vessels) on coronary angiography. Three types of vascular dysfunction were assessed: 1) Vasomotor dysfunction (VMD) defined as epicardial or microvascular vasospasm on acetylcholine provocation, 2) Coronary microvascular dysfunction (CMD) defined as coronary flow velocity reserve (CFVR) ≤2.5 on echocardiography of the LAD on adenosine stimulation and 3) Reactive Hyperaemia Index (RHI) ≤1.67 as a measure of peripheral endothelial dysfunction. Blood samples were analysed for 184 protein biomarkers related to cardiovascular disease. Correlations between biomarkers and results of vascular function assessments were analysed with Pearson's correlation coefficient and visualized with volcano plots. Significantly correlated biomarkers (p<0.05) were tested in prediction models for their incremental value over age and gender with C-statistics.
Results
CFVR was correlated to 24 biomarkers before (figure 1a) and 2 biomarkers after adjustment for age and gender. The basic prediction model had AUC of 0.68 and was not significantly improved by adding biomarkers (figure 2a). RHI was correlated to 27 biomarkers before (figure 1b) and 10 biomarkers after adjustment for age and gender. The clinical prediction model was significantly improved (p=0.037) by adding TRAIL R2 and IL-18, in addition to age and gender, with an AUC of 84.4 (figure 2b). VMD was correlated to 14 biomarkers before (figure 1c) and 6 biomarkers after adjustment for age and gender. The prediction model was significantly improved (p=0.011) by adding HSP-27, RARRES-2 and SERPINA-12 in addition to age and gender in prediction of VMD with an AUC of 85.4 (figure 2c).
Conclusion
Several biomarkers were associated with vascular dysfunction in ANOCA patients with little overlap between different endotypes. We identified biomarkers that may contribute to the understanding of the underlying pathophysiology and have applications for screening. Results need to be confirmed in larger studies.

Abstract
Lung cancer is one of the main causes of death worldwide. Published data show the use of interferons (IFNs) in treating lung tumours. IFNs also have potential for their antiproliferative, antiangiogenic, immunoregulatory and proapoptotic effects. IFN-γ functions as an anticancer agent against various forms of cancer. This study aimed to investigate the effect of IFN-γ liposome (nano) on peripheral lymphocytes from 20 individuals in each group: lung cancer patients compared to healthy individuals. The effectiveness of IFN-γ liposome against oxidative stress was also evaluated in this study. A concentration of 100 U·mL−1 of IFN-γ liposome was used to treat the lymphocytes in the Comet and micronucleus assays based on the preliminary test for the optimal dose. The lymphocytes from lung cancer patients presented with higher DNA damage levels than those of healthy individuals. In healthy individuals, IFN-γ liposome did not cause any DNA damage in the lymphocytes. Also, it caused a significant reduction in DNA damage in the lymphocytes from lung cancer patients in both the Comet and micronucleus assays. The 100 U·mL−1 of IFN-γ liposome significantly reduced the oxidative stress caused by H2O2 and appeared to be effective in both groups using the Comet and micronucleus assays. Results from both Comet and micronucleus assays were consistent. The data obtained indicated that IFN-γ in both forms (IFN-γ bulk and IFN-γ nanoliposome) may potentially be effective for the treatment of lung cancer and showed the ability of IFN-γ liposome to reduce DNA damage more than the bulk form.

Abstract
Introduction: The study aimed to target the current practices of the orthopaedic community in outpatient (OPD), emergency (ER) and surgical services (OT) during COVID-19. Material and method: This study surveyed 303 orthopaedic surgeons from all over Pakistan. The survey had 30 questions targeting the setup of outpatient, emergency and operation services in orthopaedic departments of different hospitals in Pakistan. Result: A total of 302 surgeons were included from 53 cities all over Pakistan. Between 35-48% of the respondents reported lack of availability of standard operating procedures in OPD, ER and in OT. Majority of the respondents noted that their OPD and surgical practice had been affected to some degree and 69% of the surgeons were only doing trauma surgery. This trend was higher in younger consultants of less than 45 years of age (p<0.001). Almost two-third of the surgeons, mostly senior (p=0.03) were using surgical masks as the only protective measure during various practices of OPD, ER and OT, while most of the setups were not assessing patients even for signs and symptoms of COVID. Almost 89% of the orthopaedic community is facing definite to mild stress during this pandemic and this has significantly affected the senior surgeons (p=0.01). Conclusion: Our study highlighted that COVID-19 has resulted in marked changes to the practices of the majority of Pakistani orthopaedic surgeons. Despite a sharp upsurge in the number of cases and mortality due to COVID-19, guidelines were still lacking at most of the settings and a substantial percentage of the orthopaedic community were not following adequate safety measures while attending to patients.

Abstract
The number of patients presenting with osteoradionecrosis (ORN) is likely to increase in future and health related quality of life (HRQOL) is a key outcome. This study aimed to report patient concerns and HRQOL in an osteoradionecrosis cohort over 12 years. Patients attended routine follow-up clinics between 2008 to 2020, where patient reported outcome (PRO) assessment was used before consultations as standard practice. The two PROs were the Patient Concerns Inventory (PCI) and the University of Washington quality of life questionnaire (UW-QOL v4). The study sample comprised 109 patients with ORN seen in 445 clinics when PCI and UW-QOL were used. At clinic, patients were in one of six ORN states: before ORN (26 with data), at diagnosis (12), and following treatment either improved (27), progressed (46), stable (63) or resolved (37). Worst HRQOL outcomes were reported in the progressive group with 50% reporting overall QOL as less than good. Pain was a major dysfunction (63%) as was physical and social-emotional functioning and this group reported many PCI issues, median (IQR) 7 (4-11). Kaplan-Meier estimates of survival with 95% CI after diagnosis with ORN were 96% (90-99%) at 12 months, 89% (81-94%) at 24 months and 73% (61-82%) at 60 months. This study indicates that ORN is a chronic condition with long-term survivorship consequences. More data through cohort studies and trials are needed to assist in decision making for individual patients.

Abstract
Abstract
Aims
Patients with heart failure with preserved ejection fraction (HFpEF) are usually older and multi-morbid and diagnosis can be challenging. The aims of this cohort study were to confirm diagnosis of HFpEF in patients with possible HFpEF recruited from primary care, to compare characteristics and health status between those with and without HFpEF, and to determine factors associated with health status in patients with HFpEF.
Methods
Patients with presumed HFpEF were recruited from primary care practices and underwent clinical assessment and diagnostic evaluation as part of a longitudinal cohort study. Health status was measured by Montreal Cognitive Assessment (MOCA), 6-minute walk test, symptoms, and the Kansas City Cardiomyopathy Questionnaire (KCCQ), and quality of life (QoL) by EQ-5D-5L visual analogue scale (VAS).
Results
151 patients (mean age 78.5±8.6 years, 40% women, mean EF 56% + 9.4) were recruited and 93 (61.6%) were confirmed HFpEF (those without HFpEF had other HF and cardiac diagnoses). Patients with and without HFpEF did not differ by age, MOCA, blood pressure, heart rate, NYHA class, proportion with atrial fibrillation, Charlson Comorbidity Index, or NT-ProBNP levels. Patients with HFpEF were more likely to be women, overweight or obese, frail, and to be more functionally impaired by 6 minute walk distance and gait speed than those without. Although not statistically significant, patients with HFpEF had clinically significant differences (>5 points) on the physical limitations, symptom burden and clinical summary subscales of the KCCQ, but did not differ by other subscales or by EQ-5D-5L VAS (70±17 vs 73±19, p=0.385). More patients with HFpEF reported daytime dyspnoea (63% vs 46%, p=0.035) and fatigue (81% vs 61%, p=0.008), but not other symptoms compared to those without HFpEF. For both groups BMI was moderately negatively correlated with KCCQ subscale scores, and 6 minute walk distance was positively correlated with KCCQ subscales.
Conclusions
Nearly 40% were not confirmed as HFpEF indicating the challenges of diagnosis. Patients with confirmed HFpEF differed by sex, overweight/obesity, frailty, functional impairment, and symptoms but not by age or comorbidities from those without HFpEF. These differences were reflected in some subscale scores of the KCCQ, but not how patients reported their quality of life on the KCCQ QoL subscale and EQ-5D-5L VAS. Older patients with HFpEF reported relatively high QoL despite poor health status by functional impairment, frailty and symptoms.

Abstract
Abstract
Background
Many patients with angina do not have obstructive coronary artery disease (CAD) when evaluated with coronary angiography. It is unknown whether echocardiographic coronary flow velocity reserve (CFVR) predicts an adverse outcome in these subjects. Previous CFVR studies have included heterogeneous patient subtypes both with and without CAD.
Purpose
To assess whether reduced CFVR predicts adverse outcome in women with angina and no CAD.
Methods
We evaluated 1853 women with angina and a coronary angiogram without stenosis. Exclusion criteria were previous myocardial infarction, coronary revascularisation, heart failure or valvular disease. Coronary microvascular function was assessed by echocardiographic CFVR. All patients were followed up for major adverse cardiovascular events.
Results
CFVR was obtained in 1681 patients (91%), median CFVR was 2.33 (IQR 2.00–2.74). During a median follow-up of 4.48 years, 96 adverse events occurred (acute myocardial infarction: 25; heart failure: 21; revascularisation: 8; stroke: 32; cardiovascular death: 10). In univariate Cox regression, CFVR (hazard ratio [HR] 2.04 [95% CI 1.39–2.94] per unit decrease in CFVR; p<0.001), hypertension (HR 2.29 [95% CI 1.46–3.59]; p<0.001) and diabetes (HR 2.13 [95% CI 1.31–3.45]; p=0.002) were associated with adverse outcome. These associations remained in age-adjusted multivariable regression. Exploratory analyses identified CFVR=2.24 as the optimal discriminating threshold. Stratification according to reduced CFVR and hypertension identified subgroups with better, intermediate and worse outcome (Figure 1). Outcome analyses excluding stroke yielded similar results.
Conclusion
Impaired CFVR predicts adverse outcome in women with angina and no CAD. Integrating CFVR and hypertension identifies high-risk patients.

Abstract
The world will never be the same after the current COVID-19 pandemic. We may have to live with the coronavirus for a long time. The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic has resulted in a major burden on the global health system and economy. This report describes the current COVID-19 landscape and its socioeconomic implications. Despite the concerns for second waves of infection, gradual lifting of lockdown restrictions has occurred worldwide to relieve economic pressures and likely contributes towards possibly surging of outbreak although region wise variation exists due to several other biological factors, such as testing capacity and basic healthcare facilities among susceptible population within that region. Different prediction models have been put forth to forecast the spread of the current outbreak. However, it is challenging to perceive the precise changes happening in the real world as every time dynamics differ same as other epidemics cannot possibly be exactly superimposed to COVID-19. Currently, to decrypt the conundrum for effective antiviral drug against SARS-CoV-2 is in full swing. Due to high rate of mortality and it expeditiously spread is it decisive to understand the biological properties, clinical characteristics, epidemiology, evolution, pathogenesis for vaccine development and pathogenicity studies against the viral curb. Instant diagnostic and adequate therapeutics serve as a major intervention for the management of pandemic containment. Our study aims to analyze the impact of current measures and to suggest appropriate administrative strategic planning rather than to make somewhat authentic prediction in relation to the current scenario. Our predictive analysis study should be helpful against prevention, cure and control of the current outbreak of COVID-19 till the availability of cure or vaccine.

Abstract
OBJECTIVE Despite optimal treatment, patients affected by non-muscle invasive bladder cancer (NMIBC) suffer from high risk of recurrence and progression. Intravescical device assisted therapies such as radiofrequency induced thermochemotherapeutic effect (RITE) and electromotive drug administration (EMDA) have shown promising effect in enhancing the effect of intravescical chemotherapies. The aim of the study was to assess clinical outcomes of these two devices in non-muscle invasive bladder cancer. METHODS A systematic literature review was performed in December 2019 using the Medline, Embase, and Web of Science databases. Only articles published in the last 10 years were considered (2009-2019). The articles were selected using the following keywords association: "bladder cancer" AND "EMDA' AND "synergo" AND "hyperchemotherapy" AND "electromotive drug administration", AND "radiofrequency induced thermochemotherapeutic" AND "RITE". RESULTS We found 16 studies published in the last ten years regarding the efficacy of RITE (12 studies) and EMDA (4 studies) in the treatment of NMIBC. Both RITE and EMDA showed promising results in the treatment of intermediate and high risk NMIBC as well as in patients affected by recurrent BCa after BCG failure. In high-risk BCG naïve NMIBC patients treated with EMDA recurrence and progression rates were 68% and 95%, respectively. Considering RITE, recurrence and progression range rates were 43%-88% and 62%-97%, respectively. Discordance results were reported regarding its effect on patients with carcinoma in situ. However, only few studies could be compared since differences exist regarding inclusion criteria with high patients' heterogeneity. Considering recurrence after BCG, recurrence and progression range rates were 29%-29.2% and 62%-83% for RITE and 25% and 75% for EMDA, respectively. CONCLUSION Delivery of intravescical hyperthermia seems to enhance the normal effect of intravescical chemotherapy instillation. Although prospective trials supported its effect on both BCG naïve and BCG failure patients, data are urgently required to validate these findings and to understand its effect on patients with carcinoma in situ.

Abstract
Tuberculous granuloma in the middle ear is an unusual entity. Herein, we report a case with short presentation of otitis media with mastoid abscess but with a CT scan showing widespread bone destruction. The cause was determined to be middle ear tuberculosis. Awareness of this entity is important, as it may cause a delay in referral to an otorhinolaryngology specialist and, subsequently, a delay in initiating treatment. Therefore, it should be considered in the differential diagnosis, especially when the usual treatment fails to produce the desired result.

Abstract
Abstract
Background
There is increasing evidence suggesting use of Mineralocorticoid Receptor Antagonists (MRA) in combination with Angiotensin Converting Enzyme Inhibitors (ACEI) or Angiotensin Receptor Blockers (ARB) to have a protective effect on chronic kidney disease patients.
Purpose
The aim of our study was to compare the antiproteinuric efficacy of ACEI monotherapy, Selective MRA monotherapy and their combination in mildly hypertensive patients with type 2 diabetes mellitus (DM) and microalbuminuria.
Methods
Seventy five patients with established diagnosis of type 2 DM, mild hypertension (systolic BP 140–159 mmHg and/or diastolic BP 90–99 mmHg) and microalbuminuria (30–299mg/g) were randomly assigned to one of three groups of therapy; ramipril 10 mg monotherapy (25 patients), eplerenone 50 mg monotherapy (25 patients) and eplerenone/ramipril 50/10 mg combination therapy (25 patients).The duration of the study was 24 weeks. All patients had measurement of blood pressure, urinary albumin/creatinine ratio, renal function tests and serum K level at baseline and at the end of the study after 24 weeks. All patients were followed up monthly till the end of the study for detection of side effects and/or treatment failure.
Results
Both ramipril and eplerenone monotherapy significantly reduced microalbuminuria after 24 weeks nearly to the same extent (37% and 38% respectively) without significant difference between both groups (P=0.95). There was more significant reduction of microalbuminuria in the eplerenone/ramipril combination group (60%) compared with ramipril and eplerenone monotherapy groups (P=0.0001).All groups showed significant reduction of both systolic and diastolic BP with more significant reduction of systolic BP in combination group compared with monotherapy groups (P<0.0001).There was insignificant elevation of serum potassium level among the three groups with slightly higher non significant incidence of sustained hyperkalemia in combination group (P=0.5). All groups showed insignificant changes in serum creatinine and estimated glomerular filtration rate.
Conclusion
Addition of eplerenone (selective MRA) to an ACE inhibitor may confer further antiproteinuric benefit with low risk of hyperkalemia compared with MRA or ACEI monotherapy.

Abstract
OBJECTIVE To compare outcomes of peripherally inserted central catheters (PICCs) placed in the upper extremity (UE) versus the lower extremity (LE) in a quaternary medical-surgical neonatal intensive care unit (NICU). RESULTS We analyzed a total of 365 PICCs of which 250 (68%) were removed for end of therapy and 115 (32%) were removed due to complications. Patients who had UE insertions compared to LE insertions were of lower gestational age (median (IQR)), 30 (26, 35) vs. 32 (27, 37) weeks respectively (p = 0.014). UE PICCs were more likely to be removed due to complications compared to LE PICCs (39.9% vs. 26.4%, RR 1.51, 95% CI 1.12 -2.03, p = 0.007). UE PICCs were more likely than LE PICCs to be removed for the complications of malposition, dislodgement, and pleural or pericardial effusions; while LE PICCs were more likely to be removed for phlebitis. There were no differences in the rates of sepsis at 13.0% vs. 12.8% for UE vs. LE respectively, or causal organisms for sepsis. Survival analysis demonstrated that LE PICCs had a longer time to removal for a complication (p = 0.031). CONCLUSIONS LE compared with UE PICCs were not associated with worse outcomes in a medical-surgical neonatal population that included a significant proportion of full-term neonates, and provide a valuable alternate site for central venous access. Increased awareness of the types of complications for UE compared with LE PICCs may help focus preventive and surveillance efforts based on PICC location, to improve safety and minimize the complications of NICU PICCs.

Abstract
Aim: This study aimed to determine the genetic and non-genetic factors affecting pre-weaning body weight (BW) and morphometry in Assam Hill goat along with the genetic parameters. Materials and Methods: The detailed information in respect of BW and body measurements of 960 animals at birth and 3 months of age belonging to three different populations of Assam Hill goat maintained at field units, namely, Batabari, Nahira, and Tetelia under “All India Coordinated Research Project on Goat Improvement” were utilized in the present study. The data were analyzed using least squares technique. Results: The least squares means for BW, height at withers (HW), heart girth (HG), and body length (BL) were 1.166±0.008 kg, 26.198±0.070 cm, 26.695±0.096 cm, and 29.482±0.119 cm at birth and 4.590±0.083 kg, 36.850±0.105 cm, 40.741±0.115 cm, and 39.703±0.108 cm at 3 months of age, respectively. Location had a significant effect on BW, HW, and BL at both birth and 3 months and on HG at 3 months of age. Season of birth exerted significant effect only on BL at birth, whereas the significant effect of sex was observed on HG and BL at 3 months of age. The heritability estimates for BW and body measurements were moderate indicating the scope of selection. The phenotypic and genetic correlations among BWs and body measurements at birth and 3 months of age were positive in direction and high in magnitude. Conclusion: On the basis of the present findings, it could be concluded that the weaning weight of kids can be considered for the selection of parent stock to increase productivity and eventually the economic efficiency. Further, animals with higher body measurements at initial phases of growth will perform better with respect to even BW at later stages of growth.

Abstract
Congenital abnormalities of the optic disc are not uncommon in clinical practice and should be recognized. Size abnormalities of the optic disc include optic disc aplasia, hypoplasia, megalopapilla, and optic disc cupping in prematurity. Among congenital excavations of the optic disc head, morning glory disc anomaly and optic disc pit can be complicated by serous retinal detachment; the papillorenal disc is an association of bilateral optic disc cupping and renal hypoplasia which should be ruled out; optic disc coloboma is caused by an abnormal closure of the embryonic fissure and can be complicated by choroidal neovascularization and retinal detachment. Other abnormalities that will be discussed are congenital tilted disc syndrome, duplicity of the optic disc head, congenital pigmentation of the optic disc head and myelinated retinal nerve fibers. All of these abnormalities can be associated with syndromes and neurological diseases, as well as other potentially blinding ophthalmological defects which can be secondarily complicated by amblyopia, strabismus and nystagmus. Thus, they should be recognized in order to plan for appropriate follow-up.

Abstract
The widespread distribution of persistent organic pollutants (POPs) in landfill leachate is problematic due to their acute toxicity, carcinogenicity and genotoxicity effects, which could be detrimental to public health and ecological systems. The objective of this study was to evaluate the effective removal of POPs - namely, p-tert-Butylphenol and Pyridine, 3-(1-methyl-2-pyrrolidinyl)-, (S)- - from landfill leachate using locust bean gum (LBG), and in comparison with commonly used alum. The response surface methodology coupled with a Box-Behnken design was employed to optimize the operating factors for optimal POPs removal. A quadratic polynomial model was fitted into the data with the R2 values of 0.97 and 0.96 for the removal of p-tert-Butylphenol and Pyridine, 3-(1-methyl-2-pyrrolidinyl), (S)-, respectively. The physicochemical characteristics of the flocs produced by LBG and alum were evaluated with Fourier Transform Infrared (FTIR) spectroscopy and Scanning Electron Microscopy (SEM). The infrared spectra of LBG-treated floc were identical with LBG powder, but there was some variation in the peaks of the functional groups, signifying the chemical interactions between flocculants and pollutant particles resulting from POPs removal. The results showed that p-tert-Butylphenol and Pyridine, 3-(1-methyl-2-pyrrolidinyl)-, (S)- obtained 96% and 100% removal using 500 mg/L of LBG at pH 4. pH have a significant effect on POPs removal in leachate. It is estimated that treating one million gallons of leachate using alum (at 1 g/L dosage) would cost US$39, and using LBG (at 500 mg/L dosage) would cost US$2. LBG is eco-friendly, biodegradable and non-toxic and, hence, strongly recommended as an alternative to inorganic coagulants for the treatment of POPs in landfill leachate.

Abstract
Landfill leachate contain persistent organic pollutants (POPs), namely, bisphenol A (BPA) and 2,4-Di-tert-butylphenol, which exceed the permissible limits. Thus, such landfill leachate must be treated before it is released into natural water courses. This article reports on investigations about the removal efficiency of POPs such as BPA and 2,4-Di-tert-butylphenol from leachate using locust bean gum (LBG) in comparison with alum. The vital experimental variables (pH, coagulant dosage and stirring speed) were optimised by applying response surface methodology equipped with the Box-Behnken design to reduce the POPs from leachate. An empirical quadratic polynomial model could accurately model the surface response with R2 values of 0.928 and 0.954 to reduce BPA and 2,4-Di-tert-butylphenol, respectively. Fourier transform infrared (FTIR) spectroscopy and scanning electron microscopy (SEM) were performed on treated flocs for further understanding. FTIR analysis revealed that the bridging of pollutant particles could be due to the explicit adsorption and bridging via hydrogen bonding of a coagulation mechanism. SEM micrographs indicated that the flocs produced by LBG have a rough cloudy surface and numerous micro-pores compared with alum, which enabled the capture and removal of POPs from leachate. Results showed that the reduction efficiencies for BPA and 2,4-Di-tert-butylphenol at pH 7.5 were 76% and 84% at LBG dosage of 500 mg·L-1 and 400 mg·L-1, respectively. Coagulant dosage and pH variation have a significant effect on POPs reduction in leachate. Coagulation/flocculation using LBG could be applied for POPs reduction in leachate as a pre-treatment prior to advanced treatments.

Abstract
INTRODUCTION Preservation of structural integrity of the endothelial monolayer and maintenance of endothelial cell function are of critical importance in preventing arterial thrombosis, restenosis and atherosclerosis. Obesity has been intimately linked with endothelial dysfunction, and reports of reduced abundance and functional impairment of circulating progenitor cells in obesity have led to the suggestion that defective endothelial repair contributes to obesity-related cardiovascular disease. METHODS C57BL/6 mice were fed a high-fat diet for either 3 or 6 months to induce obesity; metabolic phenotyping was then carried out before femoral artery wire injury was performed. Endothelial regeneration was then quantified. Mononuclear cells and myeloid angiogenic cells were cultured and characterized for pro-angiogenic properties. RESULTS No impairment of endothelial regeneration following mechanical endothelial injury in diet-induced obese mice when compared with chow-fed controls was observed, despite the induction of an adverse metabolic phenotype characterized by glucose intolerance and insulin resistance. Dietary-obese mice had increased numbers of circulating myeloid angiogenic cells, which retained normal functional properties including intact paracrine angiogenic effects. CONCLUSION Preserved endothelial regeneration despite metabolic dysregulation in dietary obese mice suggests that compensatory mechanisms mitigate the deleterious influence of insulin resistance on endothelial repair in obesity.

Abstract
Venous thromboembolism (VTE) is a common clinical problem that is associated with substantial morbidity and mortality. The aim of this study was to describe the clinical practices in VTE prophylaxis in university and peripheral hospitals in Morocco. This is a national, cross-sectional, multicenter, observational study assessing the management of the VTE risk in selected Moroccan hospitals (four university and three peripheral). The thromboembolic risk of the selected patients was assessed according to the American College of Chest Physicians (ACCP) guidelines (2008). We hypothesized that interventions for VTE guideline implementation in those hospitals may improve prophylaxis use for hospitalized patients. A total of 1318 patients were analyzed: 467 (35.5%) medical and 851 (64.5%) surgical. The mean age of patients was 52.6 ± 16.5 years, and 52.7% were female. A total of 51.1% patients were considered to be at risk of VTE according to ACCP guidelines and were eligible for thromboprophylaxis (TP). Medical patients were more likely to present risk factors than surgical patients (53.6 vs. 50.7%, respectively). TP was prescribed for 53.1% of these patients, 57.4% in at-risk surgical patients and 50.3% in at-risk medical patients. TP was also prescribed for 42.9% of non-at-risk patients. The concordance between the recommended and the prescribed prophylaxis was poor for the total population (kappa = 0.110). TP did not improve sufficiently in our hospitals, even after implementation of the guidelines. New strategies are required to appropriately address TP in hospitalized patients.

Abstract
The torque teno virus (TTV) has a heterogeneous genome and its role in hepatitis C (HCV) infection is still controversial, therefore the purpose of the present study was to determine if there is any association between Hepatitis C and TTV co-infection and to determine the phylogenetic relationship between existing types in the Pakistani population. A total of 500 individuals (250 HCV positive patients and 250 healthy controls) were selected. DNA was extracted from serum samples and polymerase chain reaction (PCR) of the open reading frame 1 (ORF1) region of TTV was performed. Out of 500 samples 9 HCV positive index cases (3.6%) and 8 healthy samples (3.2%) were found to be positive for TTV. A comparison was made between TTV sequences reported from all over the world with the ones obtained in the present study by sequencing of TTV positive samples followed by phylogenetic analysis using maximum parsimony (MP) method. Our results indicated that the virus was undergoing divergent evolution as very high sequence diversity was found in the ORF1 gene. The study also shows that association between HCV and TTV was not found. Because the virus was found to be affecting both healthy individuals and HCV infected population with almost same frequency. Therefore a thorough screening of TTV virus at the population level is required in order to draw a comprehensive inference.

Abstract
OBJECTIVE To evaluate the quality of ultrasound images obtained with cassava flour slurry (CFS) compared with conventional gel in order to determine objectively whether CFS could be a true low-cost alternative. DESIGN Blinded non-inferiority trial. SETTING Obstetrical ultrasound unit in an academic medical centre. POPULATION OR SAMPLE Women with a singleton pregnancy, undergoing anatomy ultrasounds. METHODS Thirty pregnant women had standard biometry measures obtained with CFS and conventional gel. Images were compared side-by-side in random order by two blinded sonologists and rated for image resolution, detail and total image quality using a 10-cm visual analogue scale. Ratings were compared using paired t-tests. Participant and sonographer experience was measured using five-point Likert scales. MAIN OUTCOME MEASURES Image resolution, detail, and total image quality. Participant experience of gel regarding irritation, messiness, and ease of removal. RESULTS We found no significant difference between perceived image quality obtained with CFS (mean = 6.2, SD = 1.2) and commercial gel (mean = 6.4, SD = 1.2) [t (28) = -1.1; P = 0.3]. Images were not rated significantly differently for either reviewer in any measure, any standardized image or any view of a specific anatomic structure. All five sonographers rated CFS as easy to obtain clear images and easy for patient and machine cleanup. Only one participant reported itching with CFS. CONCLUSIONS CFS produces comparable image quality to commercial ultrasound gel. The dissemination of these results and the simple CFS recipe could significantly increase access to ultrasound for screening, monitoring and diagnostic purposes in resource-limited settings. FUNDING This study was internally funded by our department. TWEETABLE ABSTRACT Low-cost homemade cassava flour slurry creates images equal to commercial ultrasound gel, improving access.
