Abstract
Radiotherapy (RT) has potential synergistic effects with chimeric antigen receptor (CAR) T but is not widely used as bridging therapy due to logistical challenges and lack of standardised protocols. We analysed RT bridging in a multicentre national cohort of large B-cell lymphoma patients approved for 3L axicabtagene ciloleucel or tisagenlecleucel across 12 UK centres. Of 763 approved patients, 722 were leukapheresed, 717 had data available on bridging therapy. 169/717 (24%) received RT bridging, 129 as single modality and 40 as combined modality treatment (CMT). Of 169 patients, 65.7% had advanced stage, 36.9% bulky disease, 86.5% elevated LDH, 41.7% international prognostic index (IPI) ≥3 and 15.2% double/triple hit at the time of approval. Use of RT bridging varied from 11% to 32% between centres and increased over time. Vein-to-vein time and infusion rate did not differ between bridging modalities. RT-bridged patients had favourable outcomes with 1-year progression-free survival (PFS) of 56% for single modality and 47% for CMT (1-year PFS 43% for systemic bridging). This is the largest cohort of LBCL patients receiving RT bridging prior to CAR T reported to date. Our results show that RT bridging can be safely and effectively used even in advanced stage and high-risk disease, with low dropout rates and excellent outcomes.

Abstract
A consensus meeting of national experts from all major national hepatobiliary centres in the country was held on May 26, 2023, at the Pakistan Kidney and Liver Institute & Research Centre (PKLI & RC) after initial consultations with the experts. The Pakistan Society for the Study of Liver Diseases (PSSLD) and PKLI & RC jointly organised this meeting. This effort was based on a comprehensive literature review to establish national practice guidelines for hilar cholangiocarcinoma (hCCA). The consensus was that hCCA is a complex disease and requires a multidisciplinary team approach to best manage these patients. This coordinated effort can minimise delays and give patients a chance for curative treatment and effective palliation. The diagnostic and staging workup includes high-quality computed tomography, magnetic resonance imaging, and magnetic resonance cholangiopancreatography. Brush cytology or biopsy utilizing endoscopic retrograde cholangiopancreatography is a mainstay for diagnosis. However, histopathologic confirmation is not always required before resection. Endoscopic ultrasound with fine needle aspiration of regional lymph nodes and positron emission tomography scan are valuable adjuncts for staging. The only curative treatment is the surgical resection of the biliary tree based on the Bismuth-Corlette classification. Selected patients with unresectable hCCA can be considered for liver transplantation. Adjuvant chemotherapy should be offered to patients with a high risk of recurrence. The use of preoperative biliary drainage and the need for portal vein embolisation should be based on local multidisciplinary discussions. Patients with acute cholangitis can be drained with endoscopic or percutaneous biliary drainage. Palliative chemotherapy with cisplatin and gemcitabine has shown improved survival in patients with irresectable and recurrent hCCA.

Abstract
The success of CD19 Chimeric antigen receptor (CAR) T-cell therapy in large B-cell lymphoma (LBCL) has been partially offset by toxicity and logistical challenges, which off-the-shelf agents like CD20xCD3 bispecific antibodies might potentially overcome. However, when using CAR T outcomes as the 'standard-of-care comparator̕ for relapsed/refractory (r/r) LBCL, a potential learning curve with implementing a novel, complex therapy like CAR T needs to be considered. To address this, we analysed 726 UK patients intended to be treated with CD19 CAR T for r/r LBCL and compared outcomes between the first year of the national CAR T programme (Era 1; 2019) and the more recent treatment era (Era 2; 2020-2022). We identified significant improvements for Era 2 versus Era 1 in dropout rate (17% vs. 27%, p = 0.001), progression-free survival (1-year PFS 50% vs. 32%, p < 0.001) and overall survival (1-year OS 60% vs. 40%, p < 0.001). We also observed increased use of bridging therapy, improvement in bridging outcomes, more tocilizumab/corticosteroid use, reduced high-grade cytokine release syndrome (4% vs. 9%, p = 0.01) and intensive care unit admissions (20% vs. 32%, p = 0.001). Our results demonstrate significant improvement in CAR T outcomes over time, highlighting the importance of using up-to-date clinical data when comparing CAR T against new treatment options for r/r LBCL.

Abstract
Renal insufficiency is a risk factor for osteoporosis and can increase risk of fracture. It may be a result of an age-related decline in renal function or chronic kidney disease. In patients with CKD, accurate diagnosis of osteoporosis or CKD-MBD is important for determining the most appropriate treatment. This was a cross sectional study was done at Institute of nuclear medicine and Allied Sciences, BSMMU, Dhaka from 1st January 2014 to 31st December 2014. Study population was total 69 postmenopausal women age over 50 years. Women with Bilateral hip replacement or bilateral hip pins or screws, metallic rods in spine, Carrying out BMD scan within the week after other radiological investigation using contrast media e.g. Barium meals or enema, IVPs were excluded from study. Clinical variables were- age (years), height (cm), weight (kg), BMI. Laboratory variables were- serum creatinine and BMD (Dexa). Estimated GFR was determined by using the serum Creatinine by MDRD formula. Renal function test and Bone mineral density (BMD) were done in all of these patients. Majority (43.4%) of the patients were in 6th decade. The mean weight was found 57.4±11.2kg. Majority 41(59.4%) patients belonged to T score at hip (-1 to -2.5) and their mean T score at hip was found (-1.1±1.1). Osteopenia and osteoporosis were found in 59.4% and 4.3% respectively according to BMD. High serum creatinine level was found in 10.1% cases. Renal function impairment was found in 79.6% of patient. Majority (50.7%) patients had mild decrease of eGFR (60-89 ml/min/1.73m²), There was Pearson's correlation (r=0.156; p=0.200) but not significant was found between age with T score at hip of the patients. Positive Pearson's correlation (r=0.112; p=0.361) was found but not significant between age and serum creatinine level. A significant negative Pearson's correlation (r= -0.274; p=0.023) was found between T score at hip and serum creatinine level of the patients. A significant negative Spearman correlation (r=-0.278; p=0.021) was found between BMD and serum creatinine of the patients. A significant positive Spearman correlation (r=0.580; p=0.001) was found between BMD and estimated GFR of the patients. This study was undertaken to evaluate the relationship between renal function and bone mineral density in postmenopausal women. Majority of the postmenopausal women were in 6th decade and most of them were overweight and obese. Renal function impairment was found in 79.6% of patient. Osteoporosis was found in 04.3% and 20.3% cases according to T score at hip and T score at lumber spine respectively. Significant negative Pearson's correlation was found between T score at hip and serum creatinine level of the patients. Significant negative Spearman correlation was found between BMD and serum creatinine of the patients. Significant positive Spearman correlation was found between BMD and estimated GFR of the patients.

Abstract
Abstract
Introduction
Extent of aortic valve (AV) calcium increases as degenerative aortic valve stenosis progresses. Initial studies postulated AV calcium (AVC) score to be a predictor of complications such as need for pacemaker implantation, paravalvular regurgitation and mortality after Trans-catheter Aortic valve Replacement (TAVR). However, evidence regarding the impact of AVC score as a predictor of post-procedural complications and mortality has been conflicting.
Objective
This study aimed to determine the prognostic impact of AVC as predictor of post-procedural outcomes and mortality in patients with severe aortic stenosis (AS) who underwent TAVR.
Methods
We retrospectively abstracted the records of 497 patients with severe AS who underwent TAVR between January 2016 and July 2019 at our institution. All patients underwent a non-contrast cardiac CT scan on a Siemens Somatom Definition Flash 128 slice scanner. AVC score using the Agatston method was obtained retrospectively. Patients were divided into two groups: 1) Non-severe AVC score group [women <1200 Agatston unit (AU) and men <2000 AU]; 2) Severe AV Calcium Score group [women >1200 AU and men >2000 AU]. Primary outcome was 1-year mortality.
Results
Among 466 patients included in the analysis, 352 patients were included severe AVC group while 114 patients were in the non-severe AVC group. Patients in the severe AVC group were older (81±8 vs 79±8 years), were predominantly males (79% vs 71%), and had less diabetes mellitus (31% vs 42%, p=0.02). Post-TAVR AV dimensionless index (0.58±0.13 vs 0.58±0.12, p=0.8) and AV mean gradient (9.5±4.9 vs 9.2±5.4 mmHg) were not statistically different between both groups. There was no statistical difference in the need for PPM (12% vs 7%, p=0.16), post-TAVR stroke (1.5% vs 0%), post-TAVR major complications (17.4% vs 10%, p=0.07), 30 day (3.7% vs 4.4%), and 1-year mortality (13.6 vs 11.4, p=0.6) between both groups.
Conclusion
Our study report that the severity of AVC score does not have a prognostic impact on major post-procedural outcomes and mortality after TAVR.

Abstract
Abstract
Introduction
Sex based differences exist in the presentation, outcomes, and management of cardiovascular diseases. Although aortic valve calcium (AVC) score has been postulated to be associated with post-procedural outcomes after transcatheter aortic valve replacement (TAVR), data on the impact of AVC score on procedural outcomes after TAVR based on sex have been scarce.
Objective
The aim of the present study was to elucidate sex related differences in the prognostic impact of AVC score as a predictor of post-procedural outcomes and mortality in patients with severe aortic stenosis (AS) who underwent TAVR.
Methods
We retrospectively abstracted the records of 497 patients with severe AS who underwent TAVR between January 2016 and July 2019 at our institution. All patients underwent a non-contrast cardiac CT scan on a Siemens Somatom Definition Flash 128 slice scanner. AVC score using the Agatston method was calculated retrospectively. Primary outcome was 1-year mortality. Patients were divided into two groups: 1) Non-severe AVC score group [women <1200 Agatston unit (AU) and men <2000 AU]; 2) Severe AVC Score group [women >1200 AU and men >2000 AU]. Cox-regression model was used to predict effect of variables on 1-year mortality in male and female patients.
Results
Among 466 patients included, 268 patients were male and 198 were female (57.5% vs 42.5%). When compared with males, female patients had significantly lower AVC score (p<0.001), aortic valve area (AVA) (p<0.001), obstructive CAD (p<0.001), and history of previous PCI (p<0.004), and CABG (<0.001) but had a significantly higher STS score (6.7±3.2 vs 5.8±3.3 P=0.01). There was no difference between need for permanent pacemaker (PPM) implantation (11% vs 9.6%, p=0.4), major complications (16% vs 15%, p=0.9), stroke (0.8% vs 1.6%, p=0.7), 30-day (3.7% vs 4%, p=0.9), and 1-year mortality (14% vs 12%, p=0.6) between males and females, respectively. Female patients required smaller bio-prosthetic valves compared with males (26±3.2 vs 30±3, p<0.001). Cox regression analysis for female patients showed BMI, hemoglobin level, and AVA independently predicted 1-year mortality, while there was no impact of severe AVC score (>1200 AU) on 1-year mortality in females. Similarly, Cox regression analysis for male patients showed there was no impact of severe AVC score (>2000 AU) on 1-year mortality in males. When males in the severe AVC group were compared with female patients in the severe AVC group, there was no difference in 30 day (4.3% vs 3.3%, p=0.82) and 1-year mortality (14.2% vs 13.3%, p=0.77). Similarly, in the severe AVC group there was no difference between need for PPM implantation (12.8% vs 12.1%, p=0.9), major complications (19.7% vs 15.8%, p=0.4), and stroke (2.2% vs 1%, p=0.6) between males and females, respectively.
Conclusion
There were no sex differences in the impact of AVC score on mortality and post-procedural outcomes after TAVR.

Abstract
BACKGROUND There is little evidence available regarding the impact of Achilles Tendinopathy (AT) on health-related quality of life (HRQOL). The primary aim of this study was to quantify the clinical and health-related quality-of-life patient-reported outcome measures for a population presenting with either mid-substance or insertional Achilles tendinopathy. METHODS A prospective comparative observational study of consecutive patients with AT presenting for extracorporeal shockwave therapy (ESWT) at a large teaching hospital. The primary outcome was assessment of a validated health-related quality of life PROMs (Euroqol EQ-5D-5L) and comparison to 2 general UK population datasets. The secondary outcomes were Visual Analogue Pain Scale (VAS-Pain) and two validated foot-specific patient reported outcome measures (Foot Function Index (FFI) and Victorian Institute of Sports Assessment-Achilles (VISA-A)). RESULTS Between March 2014 and June 2021, 320 consecutive patients (125 male; 195 female) were diagnosed with AT and referred for a first course of ESWT. EQ-5D-5L PROMs were prospectively collected for 303 of these patients (94.7%). The mean age (± standard deviation(SD)) was 52.1 ± 11.4 years. The mean EQ-5D-5L Index score (mean±SD) for the AT cohort was 0.783 ± 0.131. Patients less than 55 years with AT had a statistically significantly worse quality of life compared with members of the same age group in the general population. The mean VAS-Pain, FFI, VISA-A clinical outcome scores were 6.0 ± 2.3, 49.5 ± 21.2 and 34.1 ± 14.4 respectively. There was a statistically significant moderate correlation between HRQOL and clinical PROMs (VAS-Pain and FFI vs EQ-5D) however there was no correlation with age. CONCLUSION This study demonstrates that patients under the age of 55 with AT have a significantly reduced quality of life compared with the general population. LEVEL OF EVIDENCE III.

Background
Ethnic minority populations in the United Kingdom (UK) are known to have higher rates of undiagnosed and poorly controlled hypertension and metabolic disease (1). Muslims in the UK make up a significant proportion of these populations, and have lower reported rates of well-being and satisfaction with health services (2). Tailoring interventions to target under-served populations and activate positive health behaviours has been shown to improve uptake and outcomes (3).
Purpose
We undertook an opportunistic pilot intervention to explore the potential of using faith-placed community assets to identify undiagnosed and poorly managed cases of hypertension, diabetes, and explore cardiovascular disease (CVD) risk.
Methods
A community event was organised for Indian-origin Tamil speaking Muslims who gathered from across the UK in November 2021. We piloted a short CVD risk assessment intervention to take place during this event, delivered by doctors from the same community. Participants consented for assessment of body mass index (BMI), blood pressure (BP), random capillary blood glucose (CBG), and manual pulse rhythm check (with a commercially available smartphone based single-lead electrocardiogram device where needed). We also calculated the 10-year CVD risk using a nationally validated 10-year CVD risk calculator. The intervention was culturally tailored, specifically with men and women examined by the same sex and participants being given an Islamic reminder on good health to encourage their involvement.
Results
35 attendees were assessed in total. 33/35 (94%) attendees were 60-years-old or less. 18/35 (51%) had an elevated blood pressure reading (systolic BP ≥ 140mmHg or diastolic BP ≥ 90mmHg on both arms), with only 3/18 (17%) having a prior diagnosis of hypertension. Only 17/35 consented to CBG measurement, of which 4/17 (23%) had random CBG levels of >11.1 mmol/L with 3/17 having CBG levels of >25 mmol/L - none of them were known to have diabetes. 9/35 (26%) had 10-year CVD risk of >10%. 6/9 (67%) of these were not on statin therapy. 24/35 (69%) had elevated BMI, with 9/24 (37%) having a BMI of ≥ 30 kg/m2. None of the attendees had an irregular pulse to suggest arrhythmia. Full characteristics are shown in Figure 1 and results are further detailed in Figure 2. In Summary, 29/35 (83%) had at least one abnormal finding on assessment. All participants with abnormal findings were signposted to seek formal diagnosis and management through their general practitioner, and were offered lifestyle advice.
Conclusions
This brief and targeted intervention was successful at detecting undiagnosed cases of probable hypertension and hyperglycaemia, as well as identifying cases who would benefit from primary CVD risk prevention. Further research is needed to understand the scalability and feasibility of this approach to wider populations.

Abstract
BACKGROUND The clinical outcomes following surgical management of insertional Achilles tendinopathy (IAT) vary depending on the surgical technique used to reattach the Achilles tendon following debridement. The aim of this study was to investigate the clinical outcomes of patients with IAT who underwent surgical management with a double-row suture bridge technique used to reattach the Achilles tendon. METHODS A retrospective review of consecutive patients diagnosed with IAT, who underwent surgical management utilising a double-row suture bridge technique (Arthex Speedbridge), and a minimum of 3-month follow-up were included. The primary outcome was the Manchester-Oxford Foot Questionnaire (MOXFQ) Index score which is a patient reported outcome measure (PROM). Secondary outcomes included EuroQol EQ-5D-5L health-related quality of life PROM and complication rates. RESULTS Between July 2013 and June 2020, 50 consecutive patients (23 male; 27 female) were included. The mean age (± standard deviation) was 52.3 ± 11.3 (range 29.0-84.3). Pre- and post-operative PROM data were available for all cases. The mean follow-up was 2.4 ± 1.9 years. The MOXFQ Index score improved from 48.5 to 12.4 (p < 0.01), EQ-5D-5L improved from 2.7 ± 0.46 to 1.2 ± 0.37 (p < 0.01), and EQ-VAS improved from 48.0 ± 18.4 to 84.1 ± 12.6 (p < 0.01). Four patients had complications which were of minimal clinical relevance and caused no deviation from routine recovery. There were no cases of tendon rupture. CONCLUSION This study has demonstrated that surgical management of IAT is safe and effective with clinical improvement in both clinical and general health-related quality of life outcome PROMs. LEVEL OF EVIDENCE IV.

Abstract
The chronic kidney disease (CKD) is associated with a variety of bone disorders and disorders of calcium and phosphorus metabolism. Bone disease associated with chronic kidney disease having higher rate of CKD progression and increased risk of death. To see the status of serum calcium, phosphate and intact parathyroid hormone in pre-dialysis CKD (stage- 3 to 5) patients. This was a across sectional study done in outpatient department of Nephrology of National Institute of Kidney Diseases and Urology, Dhaka, between 1st June 2012 to 31st May 2013. The patients of CKD stage 3, 4 and 5 yet not on dialysis attending out patients department of Nephrology, NIKDU by using MDRD-4 equation according to K/DOQI guidelines and reviewing previous medical records and investigation reports were enrolled in this study. There after serum calcium (corrected for serum albumin), phosphate and iPTH levels were measured and compared with the recommended target ranges in K/DOQI guideline. The number of patients with serum levels according to K/DOQI guidelines for different stages CKD(3,4,5) were as follows: serum calcium: 56.6, 58.5 and 76.7; serum phosphate: 55.2, 58.5 and 56.7; iPTH 37.9, 12.2 and 36.7 and Ca x P product 100.0, 97.6 and 86.7, respectively. The percentages of patients (who received drug) with serum calcium levels within according to K/DOQI guidelines for stages 3, 4 and 5 were as follows: serum calcium: 63.2%, 64.7% and 83.3%; respectively, serum phosphate: 63.2%, 61.8% and 66.7%; respectively, iPTH 42.1%, 14.7% and 4.7% and Ca x P product 100.0%, 100.0% and 87.5%, respectively. On the other hand patients who didn't receive drug the percentages of patients with serum calcium levels according to K/DOQI guidelines for CKD stages 3, 4 and 5 were as follows: serum calcium: 50.0%, 28.6% and 50.0%; respectively, serum phosphate: 40.0%, 42.9% and 16.7%; respectively, iPTH 30.0%, 14.7% and 16.7% and Ca x P product 100.0%, 85.7% and 83.3%, respectively. The patients achieving the four recommendations of K/DOQI guidelines was 4(13.8%) in stage-3, 3(7.3%) in stage-4 and 5(16.7%) in stage-5. More than half of the pre-dialysis patients of CKD were within target range of serum calcium and phosphate recommended in K/DOQI guideline and this proportion was more in those who were taking both phosphate binder and Vit-D. Ca x P was within target range in almost all patients so it may not be an important parameter for therapeutic decision making. However majority of the patients were out of target range of iPTH even though having normal serum calcium and phosphate level. So emphasis should be given in monitoring of iPTH level in early stages of CKD.

Abstract
Aim: To compare the outcomes in term of complication of Veress Needle Insertion (VNI) to Direct Trocar Insertion (DTI) for creation of pneumoperitoneum in laparoscopic cholecystectomy.
Design: Randomized controlled trial
Place and Duration of Study: The current analysis was conducted at Khawaja Muhammad Safdar Medical College Surgical Department, Allama Iqbal Memorial Hospital and Govt. Sardar Begum Teaching Hospital, Sialkot from September 27, 2017, to September 26, 2020.
Methodology: A total of six hundred and eight (n=608) patients, having age 30 to 75 years planned for laparoscopic cholecystectomy were included in this study. Patients were randomly divided into two groups, Group A (Direct Trocar Insertion), Group B (Veress Needle Insertion). Both groups had age and sex matched males and female. All trocars and veress needle used were disposable, with a safety shield. The primary outcome of our study was to compare the complications to assess the safety levels, while total time taken by the procedure and mean time for laparoscopic entry were the secondary end points. The collected data was analyzed by using software SPSS version 22. Chi-square test was used to check the significance of variance. P-value less than 0.05 remained the statistically significant.
Results: The complication rate in VNI group were significantly greater than the DTI group (p < 0.01), the duration of surgery between the two groups was not significantly different (p > 0.05), but we found statistically significant difference in mean laparoscope insertion time (DTI 3.4+ 1.4 versus VNI 4.8+ 0.7 minutes, p < 0.001).
Conclusion: From the results of our study, it can be concluded that the direct trocar insertion is a safe alternative to veress needle insertion in laparoscopic cholecystectomy as it is associated with fewer complications.

Abstract
Every year, the poultry industry experiences significant economic losses due to epidemics of Newcastle disease virus (NDV). Developing new vaccines by identifying and using the immunogenic hemagglutinin-neuraminidase (HN) protein can protect the poultry industry. In the present study, the full-length HN protein was expressed in Escherichia coli (E. coli) BL21 (DE3) cells, purified via affinity chromatography and detected via western blot analysis using His-specific antibodies. The purified HN protein was further evaluated in chickens to study the immune response against NDV. The successful production of HN-specific IgY proved the activity of the purified HN protein. IgY was present in the serum of immunized chickens. However, the immune response was higher in chickens immunized with purified HN protein along with complete and incomplete adjuvants than in chickens immunized with only the HN protein. Keywords: protein; Newcastle disease virus; poultry; infectious diseases; vaccines.

Abstract
BACKGROUND Hepatitis C virus (HCV) infects more than 170 million people worldwide that represents a major threat to global public health. Several viruses including HCV have developed mechanisms against the cellular responses essentially "hijacking" the antiviral responses generated against it. Interleukin 22 activated JAK-STAT pathways are responsible for several functions including liver regeneration, antiviral responses and cell cycle regulation. OBJECTIVES Present study aims to un-reveal the speculated role of HCV core protein in perturbing IL-22 mediated JAK-STAT pathway. Principally investigating through interaction with IL-22 and SOCS-3 proteins. PATIENTS AND METHODOLOGY Total 36 liver transplant patients were enrolled in the study. Out of which 24 were found HCV + ve. Immunohistochemistry (IHC) based qualitative expression analysis of IL-22, SOCS-3 and HCV core protein was carried out. Microscopy was performed for detection and visualization of immunostained liver tissues and biopsies. RESULTS Hepatic expression of IL-22, HCV core protein and SOCS-3 showed that SOCS-3 expression levels were considerably high compared to HCV core and IL-22 protein. IL-22's moderate to high expression was found in 70% of the liver transplant patient sample. Total 87% patients showed moderate to high SOCS-3 expression. However, the overall expression of HCV core was stronger in 87% of cirrhotic patients and 14% in HCC patients. Suggesting the presence of HCV core protein clearly impacted the IL-22 mediated cellular signaling (JAK-STAT pathway leading towards hepatocarcinogenesis. CONCLUSION HCV core and IL-22 and SOCS-3 molecules are found to be correlated statistically under this study. Concluded from this study that HCV core protein plays a potential role in diverging the hepatocytes from normal to carcinogenic. One cell signaling path cannot decide, the direct role of a single viral protein in developing viral induced hepatocarcinogenesis. Interpreting the complex network of cell signaling involved in HCC development is impractical to study under single study. That is why step by step unmasking the interactive role of few molecules under single study is the ideal way to resolve the impact of viral proteins on cell signaling. SOCS-3 is mediator for dysregulating IL-22 mediated liver regenerative pathway. Moreover, SOCS-3 and STAT-3 molecules are proposed to be a potential therapeutic target for managing HCC progression.

Abstract
Plants have been as medicinal mediators for centuries. Recent trends in agro-biotechnology however, improved the therapeutic roles of plants to a significant level and introduced plant-based oral vaccine which can arouse an immune response in consumer. Although conventional vaccines against infectious diseases have been administrated for years the discovery of plant-based oral vaccines can potentially replace them completely in the future. The probable limitations in conventional vaccines are found to be overcome by plant-based oral vaccines. Humans and animals will no longer be dependent upon local or systemic administration of vaccines but they will just receive the vaccines as a routine food. For the purpose, gene of interest is introduced into plant through transformation, and expression of specific antigen is obtained in plant products which are then consumed by humans or animals. Therefore, plants can serve as bioreactors or bio-factories for production of edible vaccines. A detailed overview about edible vaccines, methods for edible vaccine production, candidate bioreactors and future perspectives of edible vaccines has been summarized in current article. The future of vaccination seems to be present within plant-based vaccination system. Keywords: vaccine; edible vaccine; infectious diseases; antigen; edible crops; oral immunization.

Abstract
The prevalence of chronic kidney disease (CKD) in Bangladesh is increasing. Chronic kidney disease refers to an irreversible deterioration in renal function which classically develops over a period of years. Initially, it manifest's only as a biochemical abnormality. Eventually loss of excretory, metabolic and endocrine functions of the kidneys leads to clinical symptoms and signs of renal failure, which are referred to as uraemia. In our country the number of CKD patient is increasing day by day, probably due to having uncontrolled DM, GN(Glumerulonephritis), uncontrolled hypertension, interstitial nephritis in addition to indiscriminate drugs & using of chemicals in fruits and foods. Objective of the study was to find out the morphological pattern of anaemia in patient with chronic kidney disease. This was a cross sectional observational study. This study was carried out at the Department of Medicine, Mymensingh Medical College Hospital, Mymensingh, Bangladesh from January 2011 to June 2011. Patients admitted in medicine ward male or female who satisfied the inclusion and exclusion criteria of the study were taken as study subjects. The socio demographic characteristics, presenting symptoms, risk factors, investigations and findings of diagnostic modalities and outcome were recorded. Mean age was 55.8 years of the patients who were included in this study, youngest patient is of 19 years old & older one is of 85 years. In this study 33 patients were male & 17 patients were female. Thirty three (33) patients were suffering from normocytic normochromic anaemia, 11 were suffering from microcytic hypochromic anaemia & rest 6 were suffering from combined deficiency. Female patient were suffering mainly from microcytic hypochromic anaemia (58.8%) & male patient suffered from normocytic normochromic anaemia (69.7%). CKD patients also suffered from microcytic hypochromic anaemia & also from combined deficiency.

Abstract
BACKGROUND Cytomegalovirus (CMV) infection causes morbidity and mortality in solid-organ transplant recipients. Drug-resistant CMV is an emerging problem with poor survival outcomes and limited therapeutic options. In this study we comprehensively address the issue of drug resistance in CMV when compared with standard therapies, such as ganciclovir (GCV) and foscarnet. METHODS We conducted a retrospective review of adult patients diagnosed with CMV after solid-organ transplant at our center between 2013 and 2017, and identified 7 resistant CMV cases. To study risk factors in the published literature, we performed an extensive database search. RESULTS All patients had documented UL97 mutations, and 3 patients harbored both UL97 and UL54 mutations. For cases with increasing viral load or failure to achieve clinical improvement despite optimal therapy, genetic resistance testing was carried out. Patients received GCV and foscarnet combination therapy. As an adjunct, CMV immunoglobulin, cidofovir, and leflunomide were added. Risk factors, including donor+/recipient- serostatus, persistent high viral replication, prolonged therapeutic GCV exposure (>2.5 months), and allograft rejection, were assessed. CONCLUSION Patients at risk, especially those with D+/R- serostatus, should be judiciously monitored for resistance. Prolonged intravenous GCV exposure increases the risk for development of drug resistance. Therefore, precise guidelines are required for prevention of long-term GCV/VGCV exposure. Investigation regarding interferon-gamma release assay and adoptive transfer of T cells in diagnosed CMV patients is warranted to improve future prophylactic and management strategies against CMV, with a potential to reduce the requirement for available toxic antiviral drugs.

Abstract
The basic idea behind this study was to discover the association and prevalence of purinoceptors in hepatitis C virus (HCV) and non-HCV hepatocellular carcinoma (HCC). Immunohistochemistry was performed to study the expression of P2X4 and P2X7 receptors on ex-planted liver tissue samples that were collected from HCC patients. Antibodies specific for the P2X4 and P2X7 receptors were used to target the specific receptors and secondary antibody was used with 3,3'-diaminobenzidine (DAB) detection system to visualize the color change in case of any positive expression There was a substantial increase in P2X4 receptor expression in HCV induced HCC as compared to non-HCV HCC. Surprisingly, there was no increase in the P2X7 receptor expression in both HCV HCC and non-HCV HCC. We conclude that P2X4 receptor expression was significant in the presence of HCV HCC. This may confirms the potential role of P2X4 receptor in the presence of virus in liver pathology. However insignificant expression of P2X7 receptor may avert our attention towards understanding the role of this receptor in pro-inflammatory and immune responses.

Abstract
Setting: Karachi, Pakistan. Objective: To assess the effectiveness of a community-based integrated approach in changing women's behaviour regarding contraceptive use. Design: The Sukh Initiative is a multipronged approach with door-to-door services using community health workers to provide quality family planning/reproductive health services at both public and private facilities and a 24/7 family planning helpline service that provides youth skill-based education. Methods: Retrospective pre- and post-intervention data using samples of 5140 and 3810 women, respectively. Results: The contraceptive prevalence rate increased by 10.7%, from 42.3% at baseline to 53.0% mid-intervention, with an increase in use of modern contraceptive methods of 9.2%. A significant association was found between door-to-door counselling and the use of contraceptive methods (OR 3.4, 95%CL 2.9-4.1) and access to public and private facilities for modern contraceptives (OR 2.4, 95%CL 2.0-3.0). However, support group meetings and 24/7 helpline use did not show any association with use of contraceptive method. Conclusion: The study helped to increase access to and choice of family planning services through a community-based approach that successfully reduced unmet needs and improved continuity in contraceptive use.

Abstract
Cardiac valve surgery is considered one of the most frequent surgical procedures in which AKI is a common & serious complication. Although serum creatinine is routinely used as a marker of renal function, it poorly reflects the immediate post operative period renal function. Within minutes to few hours after a renal insult, plasma neutrophil gelatinase associated lipocalin (pNGAL) is released. The aim of this study was to assess the superiority of pNGAL over serum creatinine in detecting AKI in early post operative period. This prospective observational study was carried out in the Department of Nephrology of National Institute of Kidney Diseases & Urology in collaboration with National Institute of Cardiovascular Diseases (NICVD) & Dhaka Shisu Hospital (DSH) from January 2015 to December 2016. Total 120 patients were selected from inpatient ward of cardiovascular surgery department. According to inclusion & exclusion criteria total 80 patients were included who was undergone cardiac valve surgery. Serum samples for pNGAL were collected from study population 6 hours after completion of surgery & stored at -80°C, serum samples were also collected for serum creatinine day before surgery, in 1st post operative day (POD1) & 2nd post operative day (POD2). Total 79 patients undergoing cardiac surgery, who met the inclusion & exclusion criteria, were consecutively included. There were 44 male (55.69%) and 35 female (40.31%) ranged from 15-60 years, with mean age of 36 years. pNGAL level in the blood of AKI patients (244.19±59.61ng/ml) 6 hours after completion of surgery was significantly higher from the non AKI patients (171.73±68.63ng/ml). A positive significant correlation was found between pNGAL 6 hours after completion of surgery & serum creatinine at POD1, POD2. This study demonstrated that level of pNGAL concentration 6 hours after completion of cardiac valve surgery increased before the rise of serum creatinine level & can thus AKI can be detected earlier by pNGAL.

Abstract
Settings: All hospitals managing drug-resistant tuberculosis (DR-TB) according to national guidelines in Pakistan. Objectives: To assess the effect of diabetes mellitus (DM) and factors associated with unfavourable outcomes in DR-TB. Methods: A cross-sectional study based on a retrospective record review of patients enrolled on DR-TB treatment from 2010 to 2014 in Pakistan. DR-TB data reported to Pakistan's National TB Control Programme on a monthly basis were used for the study. Result: Among 5811 patients enrolled on second-line drugs, 8.8% had DM. Overall, 68.9% had favourable outcomes. No association was found between DM and DR-TB treatment outcomes (risk ratio 0.90, 95%CI 0.74-1.05). Unfavourable outcomes were more frequent among DR-TB patients with human immunodeficiency virus (HIV) co-infection (OR 11.58, 95%CI 2.20-60.72), extensively drug-resistant TB patients (OR 5.36, 95%CI 1.00-28.72), patients with exposure to both first-line and second-line anti-tuberculosis drugs (OR 2.45, 95%CI 1.21-4.97) and those with a previous history of treatment in the private sector (OR 1.53, 95%CI 1.16-2.02). Conclusion: Although there were limitations to correctly measuring DM and its management, DM appears not to be a risk factor for unfavourable outcomes in DR-TB patients in our study. DR-TB and HIV co-infection, second-line drug resistance and history of treatment in the private sector were nevertheless more frequently associated with adverse outcomes.

Abstract
This study was conducted to determine the sero-prevalence of foot and mouth disease (FMD) in buffaloes (Bubalus bubalis) slaughtered at Islamabad slaughterhouse, Pakistan. Sera and oro-pharyngeal (OP) fluid were collected from 630 healthy buffaloes. These animals originated from various livestock markets from 14 districts of Punjab. The age of animals ranged from 1 to 15 years. Sera were analyzed using FMD virus (FMDV) nonstructural proteins (NSP) and indirect ELISA. The sero-prevalence of FMD was 47.1% (n=297). There was a strong association between age of animal and its risk of being positive for FMD NSP ELISA (Odds ratio 1.27; p<0.001; CI 1.22-1.32). The OP fluids were tested for the presence of FMDV by real time PCR. FMDV specific signals were detected in 33 samples (11.1%). Virus recovery attempts were made after treating them with tri-chloro-tri-flouroethane onto LFBK cell line and four FMD isolates were recovered. This study indicated high sero-prevalence of FMDV in buffaloes slaughtered at abattoir in Islamabad. Furthermore, the virus recovery from these animals is suggestive of their possible role in persistence and transmission of FMDV to other animals.

Abstract
Isolated CABG (coronary artery bypass grafting) has the lowest incidence of AKI (Acute Kidney Injury), followed by valvular surgery and then, combined CABG with valvular surgery. Due to the difference in baseline characteristics and in surgery type, the range of incidence is between 8.9 and 39% based on RIFLE (Risk Injury failure loss end stage kidney disease) or AKIN (Acute Kidney Injury Network) criteria. The advent of novel biomarkers of kidney injury has opened a new era of early detection and prognosis prediction for AKI. NGAL is a small molecule of 178 amino acids that belongs to the super family of lipocalins, which are proteins specialized in binding and transporting small hydrophobic molecules. The expression of NGAL raises 1000 fold in humans and rodents in response to renal tubular injury and it appears so rapidly in the urine and serum that it is useful as an early biomarker of renal failure. The role of plasma NGAL to classify AKI severity and predict the need for RRT (renal replacement therapy) after cardiac surgery has been suggested. Although study subjects were more or less from same cohort (All undergone cardiac surgery), previous studies showed that NGAL raised differently in different proportion. NGAL as an early AKI marker has successfully passed through the pre-clinical, assay development and initial clinical testing stages. It is badly need to enter in a consensus about the cutoff value of NGAL which should help the physician about leveling a case as AKI or non AKI and their consequence management.

Abstract
BACKGROUND Kidney transplantation is the optimal treatment for end-stage renal disease in children. However, long-term graft survival has not significantly improved among pediatric patients. OBJECTIVE To investigate the determinants of long-term graft survival among Iranian pediatric recipients of kidney transplantation. METHODS In a single-center cohort study, we studied 314 pediatric kidney transplantations performed from 1989 to 2013 at Dr. Shariati Hospital, Tehran, Iran. Different variables were collected for each patient and graft survival rates were calculated. RESULTS After a mean±SD follow-up period of 15.8±4.0 years, the mean±SD graft survival rate was 14.5±0.5 years; the 1-, 5-, 10-, and 20-year mean graft survival rates were 90%, 81%, 62%, and 62%, respectively. The corresponding patient survival rates were 100%, 99.4%, 97.8%, and 96.5%, respectively. Pre-emptive transplantation (p=0.006), and living graft donation (p=0.002) led to higher graft survival, while acute rejection (p=0.002), and primary disease of primary hyperoxaluria (p=0.001) led to lower graft survival. Chronic rejection was the most frequent cause of graft loss. CONCLUSION Short-term graft survival still outpaces the long-term outcome. Modifying the mentioned determinants, with more intense immunosuppression for greater prevention of acute and chronic rejection, and increased rate of pre-emptive transplantation and living donor transplantation, long-term graft survival may significantly improve in future.

Abstract
Successful disease management requires a rapid and sensitive diagnosis method that can recognize early infection even before the manifestation of its clinical signs. The only available field diagnostic tests for foot-and-mouth disease (FMD) are lateral flow devices, commonly known as chromatographic strips. Low sensitivity and inability to detect FMD virus (FMDV) at the serotype level are limitations of lateral flow devices. Therefore, a reverse transcriptase loop-mediated isothermal amplification (RT-LAMP) was standardized using universal and sero-type specific genes in a single tube. This test does not require sophisticated equipment and can detect FMDV at serotype level in about 60 min. In addition, the sensitivity and specificity of this test is comparable to conventional reverse transcriptase PCR and real time PCR (rRT-PCR).

Abstract
Four major volatile components emitted from flowers ofAbelia grandiflora were identified based on retention time using two capillary columns of different polarities and electron impact mass spectrometry. These are phenylacetaldehyde, benzaldehyde, 2-phenylethanol, and benzyl alcohol. A blend of these compounds was as effective as a cluster of flowers in stimulating upwind flight by maleTrichoplusia ni to the source in a wind-tunnel test. Phenylacetaldehyde or 2-phenylethanol were each as effective as the complete blend in stimulating source location by male moths. Attraction to a source of the synthetic blend was demonstrated in virgin males and females and mated males and females, but virgin moths of both sexes were more likely than mated moths to complete the sequence of behavioral responses necessary to locate the odor source.

Abstract
BACKGROUND Genetic predisposition to psoriasis, an inflammatory skin disease affecting 0·2-4% of the world population, is well established. Thus far, 41 psoriasis susceptibility loci reach genome-wide significance (P ≤ 5 × 10(-8) ). Identification of genetic susceptibility loci in diverse populations will help understand the underlying biology of psoriasis susceptibility. OBJECTIVES The primary objective of this study was to examine psoriasis susceptibility associations previously reported in Chinese and caucasian populations in a Pakistani cohort. METHODS Blood samples and phenotype data were collected from psoriasis cases and controls in Islamabad, Pakistan. DNA was isolated and genotypes of selected susceptibility markers were determined. The data were analysed using χ(2) tests or logistic regression for psoriasis association. RESULTS HLA-Cw6 showed the strongest association [odds ratio (OR) 2·43, P = 2·3 × 10(-12) ]. HLA-Cw1 showed marginally significant association (OR 1·66, P = 0·049), suggesting that the HLA-Cw1-B46 risk haplotype may be present in the Pakistani population. Three other loci (IL4/IL13, NOS2, TRAF3IP2) showed nominally significant association (P < 0·05). CONCLUSIONS HLA-Cw6 is strongly associated with psoriasis susceptibility in the Pakistani population, as has been found in every other population studied. In addition, HLA-Cw1 showed marginal association, reflecting the relative geographical proximity and thus likely genetic relatedness to other populations in which the HLA-Cw1-B46 haplotype is known to be associated. A larger cohort and a denser marker set will be required for further analysis of psoriasis associations in the South Asian population.

Abstract
MicroRNAs (miRNAs) play a crucial role in tumor progression and metastasis. We, and others, recently identified a number of miRNAs that are dysregulated in metastatic renal cell carcinoma compared with primary renal cell carcinoma. Here, we investigated three miRNAs that are significantly downregulated in metastatic tumors: miR-192, miR-194 and miR-215. Gain-of-function analyses showed that restoration of their expression decreases cell migration and invasion in renal cell carcinoma cell line models, whereas knockdown of these miRNAs resulted in enhancing cellular migration and invasion abilities. We identified three targets of these miRNAs with potential role in tumor aggressiveness: murine double minute 2, thymidylate synthase, and Smad Interacting protein 1/zinc finger E-box binding homeobox 2. We observed a convergent effect (the same molecule can be targeted by all three miRNAs) and a divergent effect (the same miRNA can control multiple targets) for these miRNAs. We experimentally validated these miRNA-target interactions using three independent approaches. First, we observed that miRNA overexpression significantly reduces the mRNA and protein levels of their targets. In the second, we observed significant reduction of the luciferase signal of a vector containing the 3'UTR of the target upon miRNA overexpression. Finally, we show the presence of inverse correlation between miRNA changes and the expression levels of their targets in patient specimens. We also examined the prognostic significance of miR-215 in renal cell carcinoma. Lower expression of miR-215 is associated with significantly reduced disease-free survival time. These findings were validated on an independent data set from The Cancer Genome Atlas. These results can pave the way to the clinical use of miRNAs as prognostic markers and therapeutic targets.

Abstract
INTRODUCTION We report the case of a 21 year old female with underlying facial lipodystrophy who presented with left lower abdominal pain, weight gain and altered bowel habit. PRESENTATION OF CASE Subsequent investigation showed a large (21cm×18cm×8cm) intraabdominal mass. At laparotomy, it was completely excised and was seen to arise from the transverse mesocolon and following histology revealed it to be mesenteric lipodystrophy. DISCUSSION Mesenteric lipodystrophy is a rare clinical entity, and part of a spectrum of disorders of sclerosing mesenteritis. This is the first reported case in a patient with pre-existing facial lipodystrophy. CONCLUSION Herein we describe a case of mesenteric lipodystrophy, discuss its management and review of the literature.

Abstract
Varicocele has been identified as an important cause of male infertility where its influence on men's reproductive capacity is due to its markedly diverse effects on the testicles. This study aimed to assess the value of ultrasonographic parameters of the spermatic veins at the inguinal and scrotal levels in varicocele diagnosis and post-operative evaluation. Forty-five infertile men associated with varicocele and 15 fertile men were subjected to history taking, genital examination and semen analysis. In addition, inguinal and scrotal ultrasonography was carried out pre-varicocelectomy and 3 months post-varicocelectomy. At both the scrotal or inguinal levels, the mean spermatic vein diameter demonstrated significant post-operative decrease compared with the pre-operative resting condition and on Valsalva' manoeuvre. The mean diameters of the pampiniform plexus of veins also demonstrated significant decreases post-operatively compared with the pre-operative resting condition or on Valsalva' manoeuvre. It is concluded that colour Doppler ultrasound is a reliable and noninvasive method that is useful not only for diagnosis but also for post-varicocele repair follow-up.

Abstract
The title compound, C15H14O5, is a natural product, isolated from Sorbus lanata Syn. Pyrus lanata (D. Don) found in Pakistan. The compound is composed of three spiro-fused rings. The dihedral angle between the mean planes of the benzene rings is 4.81 (13)°. The methoxy groups are oriented at dihedral angles of 74.44 (14), 83.0 (2) and 66.3 (2)° with respect to the planes of the benzene rings to which they are attached. The molecule is consolidated by three intramolecular O—H⋯O and C—H⋯O hydrogen bonds. In the crystal, molecules are linked by intermolecular O—H⋯O hydrogen bonds, forming infinite chains along the b axis.

Abstract
Inactivation or loss of the tumour suppressor Ras associated domain family 1 isoform A (RASSF1A) allele has been described in breast cancer. Recently, a missense polymorphism predicting p.A331S in RASSF1A was associated with an increased risk of breast cancer and early-onset breast cancer in BRCA1 and BRCA2 mutation carriers. We genotyped p.A331S RASSF1A in 854 independent, familial, white breast cancer patients (645 BRCA mutation negative, 119 BRCA1 and 90 BRCA2 positive) and compared the genotype in 331 healthy women. The RASSF1A p.A331S variant was not more common in the familial breast cancer cases than in the controls (P = 0.27). Subset analysis demonstrated no association in the BRCA1 (P = 0.26), BRCA2 (P = 0.16) or BRCA negative (P = 0.30) samples. Hence, the RASSF1A p.A331S polymorphism is not confirmed as a significant germline contributor to familial breast cancer susceptibility.
