Abstract
Residing obligatorily as amastigotes within the mammalian macrophages, the parasite Leishmania donovani inflicts the potentially fatal, globally re-emerging disease visceral leishmaniasis (VL) by altering intracellular signaling through kinases and phosphatases. Because the phosphatases that modulate the VL outcome in humans remained unknown, we screened a human phosphatase siRNA-library for anti-leishmanial functions in THP-1, a human macrophage-like cell line. Of the 251 phosphatases, the screen identified the Ca++-activated K+-channel-associated phosphatase myotubularin-related protein-6 (MTMR6) as the only phosphatase whose silencing reduced parasite load and IL-10 production in human macrophages. Virulent, but not avirulent, L. donovani infection increased MTMR6 expression in macrophages. As virulent L. donovani parasites expressed higher lipophosphoglycan, a TLR2-ligand, we tested the effect of TLR2 stimulation or blockade on MTMR6 expression. TLR1/TLR2-ligand Pam3CSK4 enhanced, but TLR2 blockade reduced, MTMR6 expression. L. donovani infection of macrophages ex vivo increased, but miltefosine treatment reduced, MTMR6 expression. Corroboratively, compared to endemic controls, untreated VL patients had higher, but miltefosine-treated VL patients had reduced, MTMR6 expression. The phosphatase siRNA-library screening thus identified MTMR6 as the first TLR2-modulated ion channel-associated phosphatase with significant implications in VL patients and anti-leishmanial functions.

Abstract
This study aims to characterize and contrast the triennial rates at which doctors prescribe PT, determine patient, doctor, and practicing characteristics related to every therapy suggestion, and assess pain relievers, lifestyle counseling, and PT as effective treatments for knee osteoarthritis (OA). We analyzed the National Ambulatory Medical Care Survey. Nonsteroidal anti-inflammatory drugs (NSAID), narcotics prescriptions, physical therapy referrals, and primary care physician visits for knee OA have been determined and evaluated. The average yearly rate after three years of therapy was determined. Using multivariable logistic modeling with adjustments for complicated sample design, we analyzed the relationships among patient, physician, and practice characteristics and treatments. Over time the patients were prescribed physical therapy to improve their lifestyle whereas the percentage of patients who were prescribed NSAIDs or drugs. Physical therapy, lifestyle therapy, and drugs were prescribed at similar rates across time for basic care doctor visits. There was an association between nonclinical characteristics and treatment suggestions, such as provider type, practice setting, and geographic proximity. Physical therapy (PT) and lifestyle counseling (LC) seem underused in patients with knee OA, but prescriptions for pain medication rose over the studied period. The treatment decisions varied due to variables outside of medicine. Increased usage of physical therapy and lifestyle changes, as well as decreased treatment variance for knee OA, are important areas for further study.

Abstract
BACKGROUND Respiratory tract infections (RTIs) are the most common reason for prescribing antibiotics in general practice. The COVID-19 pandemic has impacted on antibiotic prescribing and delivery of primary care in Ireland. OBJECTIVES To assess the quality of antibiotic prescribing, the impact of the COVID-19 pandemic and identify opportunities for antimicrobial stewardship (AMS) in Ireland. METHODS Point prevalence audit surveys for RTI consultations were conducted as part of a European study at three time periods: January-February 2020, March-May 2020 and March-May 2021. Antibiotic prescribing was assessed and comparisons made between the three time periods. RESULTS In total, 765 consultations were recorded, which were mainly face to face before the pandemic, but changed to predominantly remote consultations during the pandemic surveys in 2020 and 2021 (82% and 75%). Antibiotics were prescribed in 54% of RTI consultations before the pandemic. During pandemic surveys, this dropped to 23% in 2020 and 21% in 2021. There was a decrease in prescribing of Red (reserve) agents in 2021. Assessment against indication-specific quality indicators showed a high proportion of consultations for bronchitis and tonsillitis resulting in an antibiotic prescription (67% and 85%). Point-of-care testing (POCT) to aid diagnosis of RTIs were utilized in less than 1% of consultations. CONCLUSIONS During the COVID-19 pandemic, there was a reduction in antibiotic prescribing. Opportunities identified to support AMS in primary care in Ireland are targeted initiatives to reduce antibiotic prescribing for bronchitis and tonsillitis and introducing POCT to support appropriate antibiotic prescribing.

Abstract
Intestinal parasitic infections (IPIs) are endemic worldwide and more prevalent in countries with unhygienic conditions. The objective of the research was to identify the prevalence of intestinal parasitic infections in rural and urban areas of Quetta, Balochistan and to check their associated risk factors including; age, gender, educational status, sanitary system and any other immunodeficiency. For this instance 204 stool samples were collected from the urban and rural population of Quetta, Balochistan. The participants with positive results for Intestinal Parasitic Infections were interviewed using close-ended questionnaire. From the findings of this study, it has been revealed that prevalence of Intestinal parasitic infections in rural and urban areas was 21%. Males were found more prevalent (66%) as compared to females (34%) due to higher risk of contacting to outer environment. The prevalence was higher in rural areas (23%). The most prevalent intestinal parasite was Entamoeba histolytica (48%). Other prevailing parasites were Hymenolepis nana (26%), Giardia Intestinalis (17%), Trichomonas hominis (5%) and Trichuris trichiura (5%). The majority of patients were having lower socio-economic (52%) and educational status (48%). Educational status of 48% patients was primary or below primary. Most of the participants with positive results did not have hand washing habit (62%) and didn't have the closed sanitary system (71%). The intestinal parasitic infections were more prevalent among children aged from 1-10 (33%). This may be a result of poor hygiene in children. The study will contribute to lower down the prevalence in the studied areas by the application of different preventive measures in future.

Abstract
Abstract
Background
Nonsteroidal, selective mineralocorticoid receptor antagonists (MRAs) have been shown to reduce cardiovascular events among patients with diabetic nephropathy, a clinical syndrome characterized by persistent albuminuria. However, prior reports have suggested a substantial underuse of MRAs among eligible patients. In real-life, it is unknown how many have urinary excretion of albumin measured, and the cardiovascular outcomes among type 2 diabetes (T2D) patients with versus without albuminuria is relatively unknown.
Purpose
To identify candidates eligible for treatment with MRAs and compare the risk of cardiovascular events in real-life T2D patients with albuminuria versus without albuminuria.
Methods
Using the Danish nationwide registers, we identified all patients ≥18 years old with prevalent T2D at index date 1st January 2015 with an albumin-creatinine ratio (ACR) and a creatinine level measured within 365 days prior to the index date. For each patient, the last ACR and estimated glomerular filtration rate (eGFR) registered prior to the index date were used. eGFR was calculated using the CKD-EPI formula. The patients were separated into two groups consisting of patients with T2D with ACR ≥30 mg/g (albuminuria) or ACR<30 mg/g (no albuminuria), respectively. Outcomes for both groups were analyzed as time-to-event as a composite cardiovascular outcome of heart failure (HF), myocardial infarction (MI), stroke, and all-cause death and each component of the composite endpoint was analyzed individually. In both groups, we estimated the 4-year absolute risk of the cardiovascular outcome and the risk of experiencing HF, MI, and stroke.
Results
A total of 158,904 patients with T2D were identified and of those 74,014 patients (47%) had urinary ACR analyzed within the last year. Of those who had ACR analyzed 29,581 (40%) patients had albuminuria. The absolute 4-year risk of the composite cardiovascular outcome in patients with albuminuria and no albuminuria was 28.6% (95% confidence interval (CI): 28.1–29.1) versus 18.7% (95% CI: 18.4–19.1), respectively. The absolute 4-year risk for the individual components were HF 7.0% (95% CI: 6.7–7.3), MI 4.4% (95% CI: 4.2–4.6), and stroke 7.6% (95% CI: 7.3–7.9) for patients with albuminuria, versus HF 4.0% (95% CI: 3.8–4.2), MI 3.2% (95% CI: 3.1–3.4), and stroke 5.5% (95% CI: 5.3–5.7) for patients with no albuminuria.
Conclusion
In Denmark, only 47% of patients with T2D had ACR analyzed within a year indicating lack of adherence to the national T2D guidelines. A total of 40% of those who had albuminuria analyzed were eligible for treatment with MRAs based on trial inclusion criteria, and the absolute 4-year risk of experiencing a cardiovascular event was significant. However, patients with no albuminuria still displayed a substantial risk of experiencing a composite event of HF, MI, stroke, and all-cause death. Our analyses may have implications for implementation of new MRAs in patients with T2D.

Abstract
The most common cause of premature death in developing countries like Bangladesh is ischaemic heart disease. Cardiac troponin-I (cTnI) is 100 percent tissue specific for the myocardium which has been shown to be a very sensitive and specific biomarker for acute myocardial infarction. As acute myocardial infarction is a stressful condition so, plasma glucose level may also increase in this condition which is stress hyperglycemia and also plasma glucose level may be used for prediction of outcome as it is a cheap and easy available test. The aim of the study is to investigate the impact of the elevation of troponin-I level with plasma glucose level of non-diabetic patients in ST-elevation myocardial infarction. This study which was comparative type of analytical and cross- sectional study carried out in the Department of Physiology, Mymensingh Medical College, Mymensingh, Bangladesh from January 2021 to December 2021. Data was collected from Cardiology Department of Mymensingh Medical College Hospital, Mymensingh. A total number of 70 subjects participated in this study and were grouped as normoglycemic ST elevation myocardial infarction- Control group (Group I) and non-diabetic hyperglycemic ST elevation myocardial infarction- Study group (Group II). The results were calculated and analyzed by using SPSS. Serum troponin-I was measured by Fluorescence Immunoassay (FIA) and plasma glucose estimated by GOD-PAP method. Data were expressed in mean±SD and statistical significance of difference among the groups were calculated by unpaired Student's 't' test. The correlation between different parameter was done by Pearson's correlation coefficient test. In this study, the result suggests that there is significant positive association between serum troponin-I and plasma glucose level in study group (hyperglycemic non-diabetic STEMI) in comparison to control group (normoglycemic STEMI). So, by this study we recommend that routine estimation of these parameters is important for prevention of complications related to acute myocardial infarction.

Abstract
This cross sectional, descriptive study was conducted at Paediatrics department of BSMMU from July 2016 to June 2018 to find out histopathological pattern of Coeliac disease according to Modified Marsh criteria and to correlate it with tissue transglutaminase IgA level. A total of 62 children (age <18 years) attending the Paediatrics department of BSMMU with clinical suspicion of celiac disease were enrolled for the study. Mean age of studied children was 7.87±4.67 years. Ratio of the male and female was 2.27:1. Maximum (66.1%) children came from middle income class family. Out of 62 children, 35.5% (22) were positive for IgA anti-tTG of who female were 11.3% and male 24.2%. Mean duration of symptoms was 44.07±21.77 months in serology positive patients and 34.49±30.52 months in serology negative patients. The age group, 10-14 year showed the highest (50.0%) prevalence of positive anti-tTG. In the tTG positive group mean Hb was 9.6±1.14gm/dl and which is lower than that in tTG negative group (11.7±1.47gm/dl). Among 22 sero-positive patients, histological changes compatible with CD were found in 19 (86.3%) cases and normal in 3 cases. Histological changes were of 3a category of Marsh was found in 12(63.2%) cases, 3b in 4(21.1%) cases and 3c in 3(15.8%) cases. Strong correlation was observed between the serological level of tTGA and histological types of CD by Modified Marsh criteria. In conclusion, screening for celiac disease may be included in diagnostic tests to investigate clinically suspected children and serum tTGA level can be used to predict histopathological severity of coeliac disease.

Abstract
Malnutrition is recognized to be a serious and common complication of chronic kidney disease (CKD) and is associated with increased morbidity and mortality in children. Early identification and swift intervention is the key in the management of malnutrition in CKD. The objective of the study was to determine the prevalence of malnutrition in children with CKD, to see the prevalence of malnutrition according to different anthropometric indices, to see the prevalence of malnutrition in different stages of CKD, to compare the nutritional status of children with CKD according to chronological age and height age. This analytical cross sectional study was done in the Department of Pediatric Nephrology of Bangabandhu Sheikh Mujib Medical University, Dhaka, Bangladesh from March 2014 to May 2015. Thirty children were enrolled in the study by purposive sampling. Nutritional assessment was done from dietary assessment by 72 hours recall and anthropometric measurements. Anthropometric indices were expressed in Z-scores and percentiles according to both chronological age and height age. Numeric data was analyzed by ANOVA and categorical data was tested by chi-square test. Difference between proportions was tested by Z-test of proportion. P value (<0.05) was considered significant. Data shows that the mean age of the studied population was 10.99±3.5 years with a male predominance. Eighteen (60.0%) children were on hemodialysis and rests on conservative management. Average calorie intake was 74.31±9.34% of estimated energy requirement (EER). The prevalence of malnutrition was 70.0% (95% CI: 53.6-86.4) according to height Z-score (HAZ), 66.7% (95% CI: 45.8-80.2) for weight Z-score (WAZ) and mid upper arm circumference (MUAC) Z-score, according to BMI percentile it was 56.7% (95% CI: 39-74.4), for mid arm muscle circumference (MAMC) the prevalence was 53.3% (95% CI: 35.5-71.1), according to arm muscle area (AMA) and arm fat area (AFA) the prevalence was 50.0% (95% CI: 38.1-67.9) and for triceps skin fold thickness (TST) it was 43.3% (95% CI: 25.5-61). Height was the most affected parameter and triceps skin fold thickness was the least affected parameter. When anthropometric indices were adjusted for height age, the prevalence was 36.7% according to BMI and TST, 30.0% according to AFA, 13.3% according to MUAC, 10.0% each for MAMC and AMA and 3.3% for WAZ. The difference in the prevalence of malnutrition according to this two approach was statistically significant in all parameters accept BMI, TST and AFA. Malnutrition was more associated with advanced stage of CKD. Low calorie intake was associated with low BMI and low serum albumin level. Serum albumin level was low in the present study population. In conclusion, prevalence of malnutrition is very high in children with CKD.

Abstract
INTRODUCTION Studies suggest an association between poly-cystic ovarian syndrome (PCOS) and chronic periodontitis (CP), both being inflammatory conditions. However, insufficient evidence assesses the impact of this inflammation on bone metabolism and bone turnover markers (BTMs). The present study aimed to determine the association between BTMs, bone mineral density (BMD), and clinical periodontal parameters in PCOS women with CP. MATERIALS AND METHODS Three groups, each with 40 newly diagnosed (1) PCOS+CP, (2) PCOS alone, (3) CP alone, and fourth group (n = 20) systemically and periodontally healthy females aged 18-30 years were included in the study. Full mouth clinical periodontal parameters, C-terminal telopeptides of type I collagen (CTX), bone alkaline phosphatase (ALP), BMD and 25-hydroxyvitamin D (VD) were recorded for all. RESULTS Low BMD (0.89 ± 0.11 g/cm2), increased CTX levels (2.76 ± 4.64 ng/ml), decreased bone ALP levels (11.09 ± 6.86 ng/ml), higher VD levels (289.02 ± 168.28 nmol/l) and poor clinical periodontal status were observed in PCOS + CP females. BMD-spine showed weak positive correlation with CTX, bone ALP, VD (r = 0.02, r = 0.07, r = 0.15, respectively) in PCOS + CP group. ANCOVA depicted covariates had no confounding effect. Multiple regression model explained 21.0% for BMD-spine and 12.7% for BMD-femur of total variability signifying association with all measured parameters among all groups. CONCLUSION Enhanced inflammatory thrust by periodontitis increases CTX levels and decreases bone ALP and BMD levels in women with PCOS. Screening PCOS women for periodontal disease and vice versa may have a direct bearing on overall bone health.

Abstract
Plant hormone signalling and the circadian clock have been implicated in the transcriptional control of isoprene biosynthesis. To gain more insight into the hormonal control of isoprene biosynthesis, the present study measured plant hormone concentrations in jasmonic acid (JA)-treated leaves of our previous model study, examined their relationship with gene expression of isoprene synthase (IspS) and hormone signalling transcription factors. Of the plant hormones, IAA and JA-Ile and their related transcription factors (MYC2 and SAUR21) were significantly correlated with IspS gene expression. Concentrations of cytokinins, isopentenyladenine (iP), trans-zeatin riboside (tZR) and cis-zeatin riboside (cZR), were similarly significantly correlated with IspS expression. However, there was no significant correlation between their related transcription factor (ARR-B) and IspS expression. The circadian clock-related gene PRR7, but not the transcription factor LHY, was highly correlated with IspS expression. These results suggest that the hormonal balance between JA-Ile and IAA plays a central role in transcriptional regulation of IspS through the transcription factors MYC2 and SAUR21, the early auxin responsive genes. The putative cis-acting elements for SAUR on the IspS promoter (TGTCNN and CATATG), in addition to the G-box for MYC2, support the above proposal. These results provide insightful information on the core components of plant hormone-related regulation of IspS under coordination with the circadian clock genes.

Abstract
The study investigated the association of orthostatic hypotension (OH) with functional position change and balance in older adults with hypertension. The presence of OH was assessed with intermittent (OH intermittent) and continuous blood pressure (OH continuous) monitoring. The change in functional position was tested with sitting to standing assessment, balance performance using activity specific balance confidence scale (ABC), and timed up and go test (TUG). Testing unilateral and bilateral standing with and without altered sensory inputs was tested using the Humac balance system. ABC, TUG, and standing up time showed no significant association with OH intermittent and OH continuous. A significant association was found between bilateral standing with eyes closed on foam surface for overall stability index and OH intermittent. Older people with hypertension may be routinely examined for OH and appropriate intervention strategies should be included for comprehensive care.

Abstract
The study was conducted to evaluate the effect of Moringa olifera on the growth and gut health of Tilapia (Oreochromis niloticus). The feed having 30% crude protein was prepared as an experimental diet with 4%, 8% and 10% M. olifera leaf supplementation, respectively. The control diet was devoid of M. olifera leaves. The 10 weeks feeding trial was carried out on 60 fish in aquaria. Fish was fed @ 3% of body weight twice a day. Diet with the high level of inclusion of M. olifera leaves significantly increased the growth rate, Survival Rate (SR), Specific Growth Rate (SGR) and Feed Conversion Efficiency (FCE) in all treatment groups compared to the control group. Similarly, Feed Conversion Ratio (FCR) gradually decreased and found highly-significant. To check the gut health of the Tilapia, random samples were selected and dissected. Nutrient agar was used as culture media to check the growth of bacteria. Pour Plate Method was used for viable colonies count by colony counter. Through staining method, the different bacteria such as Escherichia coli, Salmonella, Shigella and Pseudomonas aeruginosa were identify abundantly in the intestine of control diet fish but less number present in treatment diets groups. These results showed that M. olifera leaves up to 10% of dietary protein can be used for Nile tilapia for significant growth and healthy gut microbiota of fish.

Abstract
Ninety days study was conducted in hapas installed in earthen ponds. Fish of an average initial weight (220g) were evenly distributed in triplicate groups within fifteen hapas. Five experimental diets labeled as T1 (25% CP and NRC recommended amino acid level) as control diet, T2 (with 2% low protein and 5% amino acid supplementation), T3 (with 2% low protein and 10% amino acid supplementation), T4 (with 4% low protein and 10% amino acid supplementation) and T5 (with 4% low protein and 20% amino acid supplementation) were prepared. Fish were fed with @3% of their body weight twice a day at 10.00 & 16:00 hour. Significantly higher percent weight gain (420.18 ± 66.84a) and specific growth rate (13499.33±1273.54a) along with improved feed conversion ratio (1.29 ± 0.09b) and hundred percent survivals were recorded during the trial. Furthermore proximate analysis of meat showed significant improvement in the crude protein level (81.77 ± 0.19a) served with diet containing 20% limiting amino acids mixture. Therefore, limiting amino acids can be a source of cost effective feed and use safely in L. rohita diet.

Abstract
Adolescent girls are vulnerable in underdeveloped and developing countries due to having public health problems regarding iron deficiency anaemia. As zinc acts as a cofactor in iron metabolism, so the deficiency of this trace element is associated with iron deficiency anaemia. This study was done to evaluate the changes of serum iron and serum zinc levels among iron deficient anaemic adolescent girls in comparison to healthy adolescent girls in Bangladesh. This prospective type of analytical cross sectional study was carried out in the Department of Physiology, Mymensingh Medical College, Mymensingh, Bangladesh from July 2019 to December 2020. Total number of 140 adolescent girl's age ranged from10-19 years included in this study. Among them, 70 healthy adolescent girls, were taken as control group (Group I). Remaining 70 Adolescent girls with iron deficiency anaemia (IDA) were taken as study group (Group II). Estimation of serum iron was determined by Ferrozine method using Globals iron kit, UK. Serum zinc levels were determined by colorimetric method with reagents. All data were expressed as mean (±SD) and statistical significance of difference among the group I ( healthy adolescent girls) and group II (adolescent girls with iron deficiency anaemia) were calculated by unpaired students' 't' test. Correlation of serum iron with serum zinc was done by Pearson's correlation coefficient test. The mean values (±SD) of serum iron level of Group I and Group II were 69.06±18.11μg/dl & 15.61±9.12μg/dl respectively. Mean values (±SD) of serum iron significantly lower in study group (Group II) in comparison with control group (Group I). The mean (±SD) of serum zinc level of Group I and Group II were 75.48±14.26μg/dl & 33.27±12.94μg/dl respectively. Mean value (±SD) of serum zinc levels were significantly lower in study group (Group II) in comparison with control group (Group I). Serum zinc level was positively correlated with serum iron and that was statistically significant. The deficiency of iron does not occur alone; rather it is typically associated and developed with hypozincemia. The study suggests on supplementing iron along with zinc to correct the deficiency especially in adolescent girls when their metabolic demand is high.

Lupeol and amphotericin B mediate synergistic anti-leishmanial immunomodulatory effects in Leishmania donovani-infected BALB/c mice. Cytokine 2021; 137:155319.

Abstract
Leishmania donovani, a protozoan parasite, inflicts the disease Visceral leishmaniasis (VL) Worldwide. The only orally bioavailable drug miltefosine is toxic, whereas liposomal amphotericin B (AmpB) is expensive. Lupeol, a triterpenoid from Sterculia villosa bark, was exhibited immunomodulatory and anti-leishmanial activity in experimental VL. Herein, we evaluated synergism between sub-optimum dose of AmpB and lupeol in anti-leishmanial and immunomodulatory effects in L. donovani-infected BALB/c mice. We observed that a combination of sub-optimum dose of lupeol and AmpB significantly reduced the hepatic and splenic parasitic burden accompanied by enhanced nitric oxide production, robust induction of Th1 cytokines (IL-12 and IFN-γ) but suppressed Th2 cytokine (IL-10 and TGF- β) production. The treatment with the lupeol-AmpB combination enhanced p38mitogen-activated protein kinase (p38MAPK), but reduced extracellular signal-related kinase (ERK-1/2), phosphorylation and up-regulated pro-inflammatory response. The present work thus indicates a lupeol-AmpB-mediated immunotherapeutic approach for eliminating the parasite-induced immunosuppression.

Abstract
Carbamazepine is a commonly used iminostilbene antiepileptic medication and it is estimated that 46.9% of the total antiepileptic drug overdose in the United Kingdom is because of this drug. The overdose of Carbamazepine can show negative effects on multiple systems, these include neurologic (ataxia, seizures, and altered sensorium), cardiac (tachycardia, hypotension) and metabolic manifestations. We reported a case of a 17-year-old girl had an increase in glucose levels after voluntary ingestion carbamazepine tablets. After ingestion, her gross random blood sugar level was increased, then physician suspected that she might be a Type I diabetic,but HbA1C[glycosylated hemoglobin] levels was found normal.Carbamazepine was discontinued and patient received symptomatic therapy. The patient had decreased levels of blood sugar level,after removal of the drug within the next day after ingestion of carbamazepine. A Naranjo assessment was obtained, indicating a definite relationship between the patient's increased in blood glucose levels and her use of carbamazepine.

Abstract
BACKGROUND Despite people living with dementia representing a significant proportion of health and social care users, until recently in the United Kingdom (UK) there were no prescribed standards for dementia education and training. This audit sought to review the extent and nature of dementia education and training offered to health and social care staff in the UK against the standards described in the 2015 Dementia Training Standards Framework, which describes the knowledge and skills required of the UK dementia workforce. METHODS This audit presents national data concerning the design, delivery, target audience, length, level, content, format of training, number of staff trained and frequency of delivery within existing dementia training programmes offered to health and social care staff. The Dementia Training Standards Framework was used as a reference for respondents to describe the subjects and learning outcomes associated with their training. RESULTS The findings are presented from 614 respondents offering 386 training packages, which indicated variations in the extent and quality of training. Many training packages addressed the subjects of 'person-centred care', 'communication', 'interaction and behaviour in dementia care', and 'dementia awareness'. Few training packages addressed subjects concerning 'pharmacological interventions in dementia care', 'leadership' and 'end of life care'. Fewer than 40% of The Dementia Training Standards Framework learning outcomes targeted to staff with regular contact with people with dementia or in leadership roles were covered by the reported packages. However, for training targeted at increasing dementia awareness more than 70% of the learning outcomes identified in The Dementia Training Standards Framework were addressed. Many training packages are not of sufficient duration to derive impact; although the majority employed delivery methods likely to be effective. CONCLUSIONS The development of new and existing training and education should take account of subjects that are currently underrepresented and ensure that training reflects the Training Standard Framework and evidence regarding best practice for delivery. Lessons regarding the limitations of training in the UK serve as a useful illustration of the challenge of implementing national dementia training standards; particularly for countries who are developing or have recently implemented national dementia strategies.

Abstract
A new set of differently hydrated barium and strontium squarates, namely poly[[triaqua(μ-1,2-dioxocyclobut-3-ene-1,2-diolato)barium] monohydrate], {[Ba(C4O4)(H2O)3]·H2O}n (1), poly[[diaqua(μ-1,2-dioxocyclobut-3-ene-1,2-diolato)strontium] monohydrate], {[Sr(C4O4)(H2O)2]·H2O}n (2), and poly[[triaqua(μ-1,2-dioxocyclobut-3-ene-1,2-diolato)barium/strontium(0.85/0.15)] monohydrate], {[Ba0.85Sr0.15(C4O4)(H2O)3]·H2O}n (3), is reported. The study of their crystal structures indicates that all the complexes crystallize in the triclinic space group P-1. Complexes 1 and 3 have a rare combination of squarate units coordinated through monodentate O atoms to two different metal atoms and through two bidentate O atoms to three different metal atoms. Furthermore, they have three coordinated water molecules to give a coordination number of nine. The squarate ligands in complex 2 exhibit two different coordination modes: (i) monodentate O atoms coordinated to four different Sr atoms and (ii) two monodentate O atoms coordinated to two different metal atoms with the other two O atoms bidentate to four different Sr atoms. All the compounds decompose to give the respective carbonates when heated to 800 °C, as evidenced by thermogravimetry/differential thermal analysis (TG-DTA), which are clusters of nanoparticles. Complexes 1 and 3 show additional endothermic peaks at 811 and 820 °C, respectively, indicating the phase transition of BaCO3 from an orthorhombic (α-Pmcn) to a trigonal phase (β-R3m). All three complexes have significant DNA-binding constants, ranging from 2.45 × 104 to 9.41 × 104 M-1 against EB-CT (ethidium bromide-calf thymus) DNA and protein binding constants ranging from 1.1 × 105 to 8.6 × 105 with bovine serum albumin. The in vitro cytotoxicity of the complexes is indicated by the IC50 values, which range from 128.8 to 261.3 µg ml-1. Complex 3 shows better BSA binding, antioxidant activity against the DPPH radical and cytotoxicity than complexes 1 and 2.

Abstract
This descriptive, cross sectional study was conducted at Bangabandhu Sheikh Mujib Medical University from July 2012 to July 2015 to see the occurrence of celiac disease in children with chronic diarrhea. A total of 62 children (age <18 years) attending the Paediatric Gastroenterology and Nutrition department of BSMMU with chronic diarrhoea were enrolled for the study. Mean age of studied children was 7.87±4.67 years. Ratio of the male and female was 2.27:1. Maximum (66.1%) children came from middle income class family. Out of 62 children with chronic diarrhea, 35.5% (22) were positive for IgA anti-tTG of whom female were 11.3% and male 24.2%. Mean duration of diarrhoea was 44.07±21.77 months in serology positive patients and 34.49±30.52 months in serology negative patients. The age group, 10-14 year showed the highest (50%) prevalence of positive anti-tTG. In the tTG positive group mean Hb was 9.6±1.14gm/dl and which is lower than that in tTG negative group (11.7±1.47gm/dl). Among 22 seropositive patients, histological changes compatible with CD were found in 19 (86.3%) cases and normal in 3 cases. Histological changes were of 3c category of Marsh was found in 3(15.8%) cases, 3b in 4(21.1%) cases and 3a in 12(63.2%) cases. In conclusion, Screening for celiac disease may be included in diagnostic tests for evaluating chronic diarrhoea in children.

Abstract
NOD like receptors (NLR) are essential pathogen associated molecular pattern receptors of cytoplasmic origin. During several intracellular parasitic infections NLR played vital role for host protective immune response against the pathogen. Amongst various classes of NLR, NOD1 and NOD2 had been extensively studied and were found to be the most active member of the NLR family. Therefore, we wanted to study the role of NOD1/NOD2 during Leishmania donovani infection and the mechanism behind the utilization of this pathway as a therapeutic approach. Using the infected model of macrophage and BALB/c mice the expression of NOD1 and NOD2 were analysed. Our study showed that NOD2 but not NOD1 has been exploited during experimental VL, leading to the imbalance between Th-1/Th-2 cytokines profile. Over-expression of NOD2 and stimulation with its ligand muramyl dipeptide leads to successful clearance of parasite. During in vivo experiments we found that arabinosylated lipoarabinomannan helps in the restoration of NOD2 and with MDP in combination leads to effective clearance of parasite which rescued host protective immunity and comparatively more effective than Mw and MDP combination resulting in increase T cell response. Consequently, our study highlighted the significance of NOD2 during infection the immune-modulations of which can be used as a therapeutic target.

Abstract
Gliomatosis Cerebri is a rare brain tumor. There is diversity of presentation in cases due to the nature of its diffuse involvement. Very recently, on February 2016 in the department of Paediatric Neurology, Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, Bangladesh we encountered a 10 years old boy who initially mimicked as tuberculoma of brain but later on diagnosed as Gliomatosis Cerebri on the basis of brain MRI and brain biopsy. Prognosis is always very gloomy regardless of the treatment strategy adopted. The boy died within one year after confirmation of diagnosis even after getting adequate medical management and radiation therapy.

Abstract
Hepatitis B virus (HBV) genomic mutations A1762T, G1764A and AG1762/1764TA cause production of HBV X protein (HBx) mutants, namely K130M, V131I and KV130/131MI. These mutations are important biomarkers for the development of cirrhosis and hepatocellular carcinoma (HCC) in chronic HBV patients. This study comparatively analyses the impact of intracellular expression of HBx mutants on HCC cell line Huh7. It was found that expression of KV130/131MI induced: cell proliferation, altered expression of cell cycle regulatory genes in favour of cell proliferation, intracellular reactive oxygen species (ROS) production and mitochondrial depolarization. KV130/131MI may be directly involved in host cell proliferation and hepatocarcinogenesis via altering expression of cell cycle regulatory genes. KV130/131MI may also play pivotal roles in fibrosis and cirrhosis via inducing ROS production and mitochondrial depolarization. Furthermore, these might be the possible reasons for higher occurrence of AG1762/1764TA as compared to A1762T and G1764A in cirrhosis and HCC patients.

Abstract
Seafood-borne diseases are a major public health hazard in the United States and worldwide. Per capita, seafood consumption has increased globally during recent decades. Seafood importation and domestic aquaculture farming has also increased. Moreover, several recent outbreaks of human gastroenteritis have been linked to the consumption of contaminated seafood. Investigation of seafood-borne illnesses caused by norovirus, and Vibrio, and other bacteria and viruses require a concrete knowledge about the pathogenicity and virulence properties of the etiologic agents. This review explores pathogens that have been associated with seafood and resulting outbreaks in the U.S. and other countries as well as the presence of antimicrobial resistance in the reviewed pathogens. The spectrum of such resistance is widening due to the overuse, misuse, and sub-therapeutic application of antimicrobials in humans and animals.

Abstract
The present investigation was undertaken to evaluate the tannery effluent toxicity stress symptoms in fish blood during a long term of exposure period. The effect of tannery effluent on various haematological parameters were evaluated exposing fresh water fish, C. punctatus to different concentration i.e., [Control, 5% Tannery effluent (TE), 10% TE and 20% TE] of tannery effluent. Exposed of fish to tannery effluent showed a significant decrease in the haemoglobin (Hb) content (9.16± 0.08), red blood cells (3.32 ± 0.12), packed cell volume (34.66 ± 0.33) and mean corpuscular haemoglobin (MCH) values, whereas significant increase in the white blood cells (WBC), erythro-cyte sedimentation rate (ESR) and clotting time was recorded with increase in exposure periods as compared to control respectively. Hb, RBC and MCHC values showed fluctuating results. The haematological parameters were decreases from 15th days of exposure periods to 45th days of exposure period. The decrease in haematological parameters clearly indicates that the exposed fishes have become anemic due to tannery effluent exposure.

Abstract
Leishmania donovani resides within the host macrophages by dampening host defence mechanisms and thereby it modulates the host cell functions for its survival. Multiple host cell factors compete during the interplay between the host and the parasite. Roles for dual-specificity phosphatases (DUSPs) are implicated in various pathological conditions. However, the reciprocity of these DUSPs was unknown in L. donovani infection in a susceptible model. Here, we show that Mycobacterium indicus pranii (Mw), an immunomodulator, reciprocally regulates DUSP1 and DUSP6 through the TLR4 pathway. Association of PKC-β with DUSP6 increases after Mw treatment resulting in decreased IL-10, phosphorylation of ERK1/2 and Arginase-1, whereas Mw treatment decreases the association between PKC-ε and DUSP1 resulting in increased IL-12, phosphorylation of p38 and inducible nitric oxide synthase expression. Silencing of DUSP1 or over-expression of DUSP6 in L. donovani-infected BALB/c mice decreases the parasite burden by inducing IL-12 and reducing IL-10 production. Therefore, we identify DUSP1 and DUSP6 as therapeutic targets, functions of which could be favourably modulated by Mw during L. donovani infection.

Mycobacterium tuberculosis infection inflicts the disease Tuberculosis (TB), which is fatal if left untreated. During M. tuberculosis infection, the pathogen modulates TLR-4 receptor down-stream signaling, indicating the possible involvement of TLR-4 in the regulation of the host immune response. Mycobacterium indicus pranii (MIP) possesses immuno-modulatory properties which induces the pro-inflammatory responses via induction of TLR-4-mediated signaling. Here, we observed the immunomodulatory properties of MIP against tuberculosis infection. We have studied the detailed signaling mechanisms employed by MIP in order to restore the host immune response against the in vitro tuberculosis infection. We observed that in infected macrophages MIP treatment significantly increased the TLR-4 expression as well as activation of its downstream signaling, facilitating the activation of P38 MAP kinase. MIP treatment was able to activate NF-κB via involvement of TLR-4 signaling leading to the enhanced pro-inflammatory cytokine and NO generation in the infected macrophages and generation of protective immune response. Therefore, we may suggest that, TLR4 may represent a novel therapeutic target for the activation of the innate immune response during Tuberculosis infection.

Abstract
Emergence of drug resistance during visceral leishmaniasis (VL) is a major obstacle imposed during successful therapy. An effective vaccine strategy against this disease is therefore necessary. Our present study exploited the SLA (soluble leishmanial antigen) and PGN (peptidoglycan) stimulated bone marrow-derived dendritic cells (DCs) as a suitable vaccine candidate during experimental VL. SLA-PGN-stimulated DCs showed a significant decrease in hepatic and splenic parasite burden, which were associated with increased production of nitric oxide and pro-inflammatory cytokines such as IL-12, IFN-γ and IL-17. Elevated level of IL-17 was accompanied with the generation of more Th17 cells. Further studies on DC provided the evidence that these SLA-PGN-stimulated DCs played an important role in providing necessary cytokines such as IL-6, IL-23 and TGF-β for the generation of Th17 cells. Interestingly, inhibition of protein kinase C-β (PKCβ) in DCs led to decreased production of Th17 polarizing cytokines, causing reduction of the Th17 population size. Altogether, our finding highlighted the important role of DC-based PKCβ in regulation of the function and generation of Th17 cells.

Abstract
Salmonella enterica subsp. enterica serovar Typhimurium is a food safety concern for raw poultry products. New and innovative application methods of antimicrobials for the reduction of Salmonella in poultry and poultry products are essential. The aim of this study was to determine the efficacy of three antimicrobial compounds against Salmonella on raw chicken meat when applied individually and in combination using a commercial spray cabinet. Raw chicken thigh meat inoculated with 5 log CFU/g Salmonella Typhimurium ATCC 53647 was passed through a spray cabinet while being sprayed with 5% lauric arginate (LAE), 0.8% vinegar solution (VS), near-neutral electrolyzed water, or deionized water. The following three experiments were carried out: (i) exposure times of 0, 15, 30, 45, and 60 s, (ii) storage at 4°C for 0, 1, 2, and 3 days after a 60-s exposure, and (iii) a combination of treatment with LAE and VS followed by storage at 4°C for 0, 1, 2, and 3 days. Analysis of variance and the Tukey test were used to determine mean significant differences (P < 0.05). The experiment was carried out in duplicate for each replicate (n = 3 × 2). In comparing individual antimicrobials, the 60-s treatment time resulted in the greatest reduction of Salmonella Typhimurium, with LAE achieving the greatest reduction (2.07 log), followed by VS, near-neutral electrolyzed water, and deionized water (0.63, 0.56, and 0.53 log, respectively). After 3 days of storage, LAE significantly (P < 0.05) reduced Salmonella Typhimurium, by 1.28 log. The combination of VS and then LAE resulted in a significantly (P < 0.05) greater reduction than using LAE followed by VS (1.61 and 0.93 log, respectively). The results of this study suggest that LAE is a viable compound to reduce Salmonella Typhimurium on raw chicken meat and that the order of application of antimicrobial agents plays a vital role.

Abstract
Objectives: To determine the health seeking behaviour of mothers / care givers of children under 5 years of age during their illnesses.Materials and methods: A descriptive cross-sectional study was conducted among 439 mothers/ care givers of under 5 year old children in an urban slum area of Dhaka city from September 2013 to February 2014. Data were collected through face-to-face interview by using a structured pre-tested questionnaire. The collected data were analyzed using SPSS version 20.0. All analyzed data were presented in the form of percentages. Chi-square test was applied wherever applicable.Results: Out of 439 mothers / care givers, most (90%) of them sought health care services during their childrens illness. [A statistically significant association was found between mothers /care givers education and sought health care services during illness of children (p=0.055). In the study, 200 (50%) of the respondents consulted drug sellers of medicine shops during their childrens illness. Others went to medical college hospital (34.6%), Government hospitals (13.5%), consulted a private practitioners (11%) and NGO facilities (6.3%). Forty (9.1%) respondents did not seek any health care with multiple reasons or responses. Majority (27, 67.5%) waited for self recovery, 21 (52.5%) had lack of money, 5 (12.5%) did not receive any advice to receive treatment. Four (10%) respondents said that the health care facility was too far to receive treatment and 3 (7.5%) respondents did not feel that treatment was necessary. [Health seeking behaviour of the mothers / care givers was statistically highly significant in educated person. They took the child to Govt. hospital (p=0.001) during illness. The relationship between health seeking behaviour and monthly family income of the respondents was statistically significant. The respondents took their child to medical college hospital (p=0.040) and also consulted drug sellers (p=0.038) during illness of the child.]Conclusion: Health education and behaviour change communication activities can be undertaken in the slum for mothers / care givers about early recognition of childhood illness and on the importance of seeking early treatment.Pulse Vol.7 January-December 2014 p.5-15

Abstract
A descriptive cross-sectional study was conducted for a period of six months in some locations of Dhaka city. Data was collected from 90 floating sex workers to find out their socio-demographic characteristics, sexual lifestyle particularly safe sex by using condom among them. Of the 90 respondents, mean age of the respondents was 22.21 (+4.87) with a range of < 18 to >26 years. 42 (46.7%) of the respondents were married. 73 (81.1%) of the respondents were the main earning member of the family. The mean family income was Taka 7700 (+3872.838). Majority 33(36.7%) of the respondents were illiterate. The main reason for accepting sex selling profession it was found that more than half i.e. 62 (68.9%) of the respondents were bluffed and 24 (26.7%) respondents accepted this profession of their own will. The duration of sex work of 29 (32.2%) of the respondents was less than 1 year (6-8 months) and 24 (26.6%) of the respondents were 4-5 years. 59 of the respondent always used condoms (65.6%). A significant number of respondents, 31 (34.4%) did not use condom. The reason for not using condom was clients dissatisfaction (25, 80.6%) and 4 (12.9%) respondents used other methods of contraception. Among the respondents, 78 (86.7%) used condom during last sexual intercourse. In the study, 45 (76.3%) respondents knew condom as a preventive measure and advocated its use in each sexual intercourse. (?² = 4.356; d f=1 P= 0.037). 60 (76.3%) of the respondents knew condom use as a preventive measure and used it in last sexual intercourse and highly significant association was found (?² = 17.61; df=1 P<0.001) between knowledge and practice. Promoting constant condom usage with clients among the female floating sex workers should be sustained and reinforced.Pulse Vol.7 January-December 2014 p.29-37

Abstract
Present study was conducted to investigate the effect of gamma irradiation on storage quality and post refrigeration shelf-life extension of cherry. Two commercial varieties of cherry fruit (Misri and Double) after harvest at commercial maturity were gamma irradiated in the dose range of 0.3 -1.5 kGy followed by storage under ambient (temperature 25 ± 2 0C, RH 70%) and refrigerated (temperature 3 ± 1 0C, RH 80%) conditions. Among treatments, dose of 1.2 and 1.5 kGy effectively maintained the storage quality and significantly (p≤0.05) delayed the decay of the cherry varieties. In samples treated with dose of 1.2 and 1.5 kGy no decay was recorded up to 9 days of ambient storage. Under refrigerated conditions, cherry samples of control and those irradiated in the range of 0.3 – 0.9 kGy started decaying after 14 days of storage. No decay was observed in 1.2 and 1.5 kGy samples of both the varieties up to 28 days of refrigerated storage. The treatments of 1.2 and 1.5 kGy gave an extension of 6 days in shelf life of cherry varieties during post-refrigerated storage at 25 ± 2 0C, RH 70% following 28 days of refrigeration. Firmness comparison of treatments revealed that dose of 1.2 kGy was found to be better compared to 1.5 kGy due to decrease in firmness observed in cherry samples irradiated at 1.5 kGy. Thus, radiation processing of Kashmiri Cheries at 1.2 kGy can prove beneficial in facilitating the marketing of the fruit to distant places other than the local markets, thereby benefiting the growers.

Red cell alloimmunisation in regularly transfused beta thalassemia patients in Pakistan. Transfus Med 2015; 25:106-10. [PMID: 25870030 DOI: 10.1111/tme.12196] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/04/2014] [Revised: 02/18/2015] [Accepted: 03/20/2015] [Indexed: 11/26/2022]
Abstract
BACKGROUND In Pakistan routine blood group typing of thalassemia patients identifies ABO and Rh(D) antigens only. Therefore, other antigen incompatibilities between blood donor and blood recipient may cause alloimmunisation. OBJECTIVE The aim of this study was to estimate the frequency of alloimmunisation and to evaluate the risk factors associated with its development in beta (β)-thalassemia patients receiving regular blood transfusions. MATERIALS AND METHODS In total 162 β thalassemia patients were included in this study. An extended red cell antigen panel was performed to detect antibodies. Patients received red cell concentrates, which were matched for ABO and Rh(D) antigens. Clinical and laboratory data were collected and analysed to estimate the frequency of alloantibodies and the factors influencing immunisation in patients on regular blood transfusion. RESULTS The median age of patients was 6·7 (range: 0·5-25) years. A total of 14 (8·6%) patients developed alloantibodies against red cell antigens. The most frequently occurring alloantibodies was anti-E (2·5%), anti-K (1·8%), anti-e (1·2%) and anti-D (0·6%). Five (3·1%) patients developed more than one red blood cell (RBC) alloantibody. Age at first transfusion in alloimmunised patients was 1·22 ± 0·87 years. The frequency of blood transfusion in alloimmunised patients was 23 ± 8·81 days and in those without alloimmunisation was 31·8 ± 16 days (p = 0·02). Logistic regression analysis showed no independent risk factor associated with alloimmunisation. CONCLUSION The frequency of transfusion was increased in patients who developed alloantibodies. Typing patients and donors to match for Rh and Kell antigens would prevent more than 90% of RBC alloantibodies and reduce the frequency of transfusion in thalassemia patients.

Abstract
Polyaniline (PAni)/Se nanocomposites have been synthesized in different compositions employing chemical route and shown excellent field emission behaviour. Detailed studies on the field emission for all composites with different concentrations of dopant are performed in an indigenously fabricated set up in a vacuum chamber with a base pressure of 10(-6) Torr at room temperature and analysed with current density versus Electric field (J-E) and Fowler-Nordheim (FN) plots. Comparative field emission results showed that 10% (w/w) doped PAni/Se nanocomposite depicts highest emission characteristics, current density and field enhancement factor with turn-on field as low as 1.2 V/µm in comparison with other composites, while pure PAni shows no field emission characteristics. These composites have also been characterized by Scanning Electron Microscope (SEM) and Fourier Transform Infrared Spectrometry (FTIR). FTIR results supply the evidence for the occurrence of the polymer in its conducting state. The ease of synthesis route and interesting field emission properties recommend these composites as a promising material for field emission based applications in vacuum micro-nanoelectronic devices and also for plastic display industry.
