Abstract
BACKGROUND In adults with an intellectual disability, health-related quality of life (HRQoL) is often measured by proxy report. This cross-sectional study investigated whether the mental health of proxy raters impacts the way they rate HRQoL. METHODS In this study, 110 carers of adults with an intellectual disability completed measures of psychological distress (Kessler-6) and HRQoL (EQ-5D-3L) about their own HRQoL and that of the care recipient. Differences between HRQoL scores as rated by the carer about themselves and the care recipient were calculated (convergence scores) and multiple regression models were fitted to estimate the association between proxy psychological distress and convergence scores for subjective/objective HRQoL controlling for support needs of the care recipient, carer age and gender of care recipient. RESULTS There was a significant association between psychological distress and subjective HRQoL convergence scores (r = .92; P = 0.03; 95%; CI: -1.76 to -0.09). There was no association between psychological distress and objective HRQoL convergence scores (r = .01; CI -0.02 to 0.001; P = 0.08). The association between psychological distress and HRQoL scores was no longer present when models did not include convergence scores. CONCLUSIONS Carers experiencing more psychological distress tended to rate their own and the care recipients' subjective HRQoL more similarly. Objective HRQoL measures did not show this convergence in scores with increasing carer psychological distress. Findings differed when the analysis approach was changed, suggesting the results above require replication in future studies.

Abstract
PURPOSE/OBJECTIVE(S) Definitive therapy for nasopharyngeal cancer includes chemotherapy and radiation (RT). Common toxicities such as xerostomia, mucositis, and hearing loss are correlated with the RT dose delivered to associated organs at risk. We hypothesized that compared to our historical experience with IMRT, the implementation of proton therapy (PT) would reduce radiation dose to organs at risks without compromising oncologic outcomes. MATERIALS/METHODS A retrospective review of all non-metastatic stage II-IV nasopharyngeal carcinoma (SCC, lymphoepithelioma, undifferentiated carcinomas) treated with definitive therapy at our institution from 2012-2022. Disease parameters and the mean dose to organs at risk were evaluated. Statistical comparison was made with the chi square test for categorical and Wilcoxon rank sum test for continuous variables. The Kaplan-Meier method was used to estimate overall survival (OS) and progression-free survival (PFS), using a log-rank test to compare IMRT and PT. PFS was defined as the time from the start of treatment to the first of either disease progression, relapse or death from any cause. PT was delivered with pencil-beam scanning in all patients. IMRT included multi-field treatment and volumetric-modulated arc therapy. RESULTS A total of 80 patients were included in analyses: 48 treated with IMRT and 32 with PT. Comparing IMRT to PT cohorts, there was no difference in the median age of patients (51 vs 55 years, p = 0.73), nor the distribution by T stage (p = 0.57) or N stage (p = 0.34) or in the percentage of patients with ECOG 2/3 performance status at presentation (p = 0.11). All but one patient received concurrent systemic therapy and there was no difference in the use of concurrent cisplatin between cohorts (83% vs 78%, p = 0.57). The most common non-cisplatin concurrent regimen was weekly carboplatin and paclitaxel. Induction chemotherapy was more commonly used in patients treated with PT (10.4% vs 25%, p = 0.04) while there was no difference in the use of adjuvant chemotherapy (10.4% vs 9.4%, p = 0.88). Among 42 cases initiating treatment since the opening of our proton center, 32 (76%) have received PT. Comparing IMRT and PT dosimetry, patients treated with PT received significantly lower mean dose to the better spared parotid gland (32.8 vs 25.7 Gy, p = 0.001), lesser spared parotid gland (35.5 vs 31.1 Gy, p = 0.047), better spared cochlea (31.5 vs 25.5 Gy, p = 0.004), lesser spared cochlea (41.8 vs 33.2 Gy, p = 0.004), larynx (44.5 vs 21.7 Gy, p<0.001), and oral cavity (42.6 vs 17.0 Gy, p<0.001). After a median follow-up time of 30 months (45 mos IMRT, 23 mos PT) the estimated 2-year PFS was 63.9% with IMRT and 90.3% with PT (p = 0.047). The estimate of 2-year overall survival was 86.8% with IMRT and 96.8% with PT (p = 0.17). CONCLUSION Comparing patients by radiation treatment modality, PT was associated with a statistically significant reduction in mean radiation dose to the parotid glands, cochlea, larynx, and oral cavity with excellent initial oncologic outcomes.

Abstract
PURPOSE/OBJECTIVE(S) Whole-lung, low-dose radiation (LD-RT) for COVID-19 requires randomization and biologic correlates to determine causality and mechanism. MATERIALS/METHODS A phase III trial randomized COVID-19 patients to physician's choice of drug therapy with or without LD-RT. Primary endpoint was intubation-free survival (IFS). The trial was designed with 80% power (two-sided log rank, alpha 0.05) to detect a hazard ratio of 0.3 after 12 intubation events. Estimating a 25% event rate, the planned sample size was 84 patients plus 25 to account for declining intubation rates and screen failures. Due to hospitalization declines and other barriers, the trial closed prematurely. Available randomized data were analyzed by intention-to-treat and combined with phase II results and immunologic correlates, using one-sided significance and an alpha of 0.1 to inform future trial design. RESULTS From Jun 2020-Jun 2022, 14 patients were randomized on a phase III trial. From Apr 2020-Dec 2020, 42 patients were enrolled on a phase II trial and blindly matched to 40 controls from contemporaneous trials. 96 total patients and 193 blood samples were available for analysis. Mean hospital duration with LD-RT was 12.9 vs 15.4 days in controls (p = 0.12). Oxygen flow rate >15 L/min (26% vs 38%, p = .27), high-flow oxygen >30 L/min (24% vs 38%, p = 0.18), non-invasive positive-pressure >60 L/min (9% vs 27%, p = 0.03), and mechanical ventilation (9% vs 24%, p = 0.05) reduced with LD-RT. Mean supplemented oxygen volume was 171,759 vs 547,626 liters in controls, with daily means of 10 vs 23 L/min (p = 0.03). Radiographs worsened in 43% vs 71% of controls (p = 0.03). Arterial blood gas mean P/F ratios improved 22% after LD-RT vs declined 8% in controls (p = 0.12). Mean days febrile were 1.8 vs 2.9 in controls (p = 0.10). Rate of myocardial injury was 47% vs 40% in controls (p = 0.77). Flow cytometry revealed 4-fold and 30-fold larger expansions, respectively, in CD8- and CD4-positive CD3+PD1+Ki67-high proliferating cytotoxic T-cells (300% vs 75% expansion, p = 0.07) and helper T-cells (200% expansion vs 6% contraction, p = 0.03) at day 7. In the randomized cohort, mean oxygen volume fell 75% with LD-RT to 78,336 vs 316,786 liters in controls (p = 0.13), mean flow rates were 5.1 vs 18.4 L/min (p = 0.13), radiographs worsened in 50% vs 100% (p = .17), P/F ratios improved 31% vs declined 68% in controls (p = 0.03), hospital duration was 8.9 vs 11.5 days (p = 0.22), and zero LD-RT patients vs one control intubated. CONCLUSION Combined analysis of a phase II/III randomized trial suggests that LD-RT prevents ventilation, reduces supplemental oxygen need, improves clinical course, and enhances immune response. LD-RT may have both immediate direct effects and delayed enhanced immunity in COVID-19. Larger multi-institutional trials are justified.

Abstract
PURPOSE Because proton head and neck (HN) treatments are sensitive to anatomical changes, plan adaptation (re-plan) during the treatment course is needed for a significant portion of patients. We aim to predict re-plan at plan review stage for HN proton therapy with a neural network (NN) model trained with patients' dosimetric and clinical features. The model can serve as a valuable tool for planners to assess the probability of needing to revise the current plan. METHODS AND MATERIALS Mean beam dose heterogeneity index (BHI), defined as the ratio of the maximum beam dose to the prescription dose, plan robustness features (clinical target volume (CTV), V100 changes, and V100 > 95% passing rates in 21 robust evaluation scenarios), as well as clinical features (e.g., age, tumor site, and surgery/chemotherapy status) were gathered from 171 patients treated at our proton center in 2020, with a median age of 64 and stages from I-IVc across 13 HN sites. Statistical analyses of dosimetric parameters and clinical features were conducted between re-plan and no-replan groups. A NN was trained and tested using these features. Receiver operating characteristic (ROC) analysis was conducted to evaluate the performance of the prediction model. A sensitivity analysis was done to determine feature importance. RESULTS Mean BHI in the re-plan group was significantly higher than the no-replan group (p < .01). Tumor site (p < .01), chemotherapy status (p < .01), and surgery status (p < .01) were significantly correlated to re-plan. The model had sensitivities/specificities of 75.0%/77.4%, respectively, and an area under the ROC curve of .855. CONCLUSION There are several dosimetric and clinical features that correlate to re-plans, and NNs trained with these features can be used to predict HN re-plans, which can be used to reduce re-plan rate by improving plan quality.

Abstract
As the incidence of neurodegeneration and cancer fatalities remains high, researchers are focusing their efforts on discovering and developing effective medications, especially plant-based drugs, against these diseases. Hence, this research aimed to investigate the neuropharmacological potentials of aerial parts of Tetrastigma leucostaphyllum, employing some behavioral models, while the antiproliferative effect was explored against a panel of cancer cell lines (MGC-803, A549, U-251, HeLa and MCF-7) using a colorimetric assay. In addition, active extracts were analyzed by GC-MS technique to identify the active compounds, where some selective compounds were docked with the particular pure proteins to check their binding affinity. Results from neuropharmacological research indicated that the total extract and its fractions may be effective (p = 0.05, 0.01, and 0.001, respectively) at doses of 100, 200, and 400 mg/kg of animal body weight. The greatest antidepressant and anxiolytic effects were found in the n-hexane fraction. The n-haxane fraction also exhibited the highest cytotoxicity against the U-251 cell line (IC5014.3 μg/mL), followed by the A549, MG-803, HeLa, and MCF-7 cell lines, respectively. From the n-hexane fraction, ten chemicals were detected using the GC-MS method. Additionally, the in-silico research revealed interactions between the n-hexane fractions' identified compounds and the antidepressant, anxiolytic, and cytotoxic receptors. The molecules showed binding affinities that ranged from 4.6 kcal/mol to 6.8 kcal/mol, which indicates the likelihood that they would make good drug candidates. This study highlighted the plant's neuropharmacological and cytotoxic properties, however, more research is needed to determine the etymological origin of these effects.

Abstract
Dillenia pentagyna Roxb. is traditionally used to treat cancer, wound healing, diabetes, and diarrhea in local tribes. This study was designed to evaluate the pharmacological potentiality of this plant. In vivo analgesic, anti-inflammatory, and antipyretic studies of the methanol extracts of D. pentagyna (MEDP) leaves were performed by using acetic acid-induced nociception, formalin-induced paw licking, and yeast-induced pyrexia assay methods, respectively. In vivo antidiarrheal activity was carried out in mice by following castor oil-induced diarrhea and gastrointestinal transit manner. In vitro thrombolytic experiment was performed employing the clot lysis activity. Besides, a molecular docking study was performed by executing the software (PyRx, Discovery Studio, and UCSF Chimera). In the acetic acid-induced writhing study, MEDP possesses significant writhing inhibition in a dose-dependent manner. It showed 50.86% of maximum inhibition of pain in the case of MEDP at a dose of 400 mg/kg body weight. In the anti-inflammatory study, maximum inhibition rate was observed at a value of 59.98 and 41.29% in early and late phases, respectively, at the dose of 400 mg/kg body weight. In the case of yeast-induced hyperpyrexia, MEDP reduced hyperpyrexia in a dose-dependent manner. In the antidiarrheal assay, MEDP moderately inhibited the occurrence of diarrhea in all the experiments. In the thrombolytic study, a moderate (17.76%) clot lysis potency has been yielded by MEDP. Again, the molecular docking simulation revealed strong binding affinities with almost all the targeted proteins. The present study suggests that the MEDP possesses remarkable pharmacological activity and this finding validated the ethnobotanical significance of D. pentagyna as the source of pain, fever, and diarrhea management agent.

Abstract
Bauhinia scandens L. (Family: Fabaceae) is commonly used to treat cholera, diarrhea, asthma, and diabetes disorder in integrative medicine. This study aimed to screen the presence of phytochemicals (preliminary and UPLC-QTOF–M.S. analysis) and to examine the pharmacological activities of Bauhinia scandens L. stems (MEBS) stem extracts. Besides, in silico study was also implemented to elucidate the binding affinity and drug capability of the selected phytochemicals. In vivo anti diarrheal activity was investigated in mice models. In vitro, antibacterial and antifungal properties of MEBS against several pathogenic strains were evaluated using the disc diffusion method. In addition, in silico study has been employed using Discovery studio 2020, UCFS Chimera, PyRx autodock vina, and online tools. In the anti-diarrheal investigation, MEBS showed a significant dose-dependent inhibition rate in all three methods. The antibacterial and antifungal screening showed a remarkable zone of inhibition, of the diameter 14–26 mm and 12–28 mm, by MEBS. The present study revealed that MEBS has remarkable anti-diarrheal potential and is highly effective in wide-spectrum bacterial and fungal strains. Moreover, the in silico study validated the results of biological screenings. To conclude, MEBS is presumed to be a good source in treating diarrhea, bacterial and fungal infections.

Abstract
Bauhinia scandens L. (Family, Fabaceae) is a medicinal plant used for conventional and societal medication in Ayurveda. The present study has been conducted to screen the chemical, pharmacological and biochemical potentiality of the methanol extracts of B. scandens stems (MEBS) along with its related fractions including carbon tetrachloride (CTBS), di-chloromethane (DMBS) and n-butanol (BTBS). UPLC-QTOF-MS has been implemented to analyze the chemical compounds of the methanol extracts of Bauhinia scandens stems. Additionally, antinociceptive and anti-inflammatory effects were performed by following the acetic acid-induced writhing test and formalin-mediated paw licking test in the mice model. The antipyretic investigation was performed by Brewer Yeast induced pyrexia method. The clot lysis method was implemented to screen the thrombolytic activity in human serum. Besides, the in silico study was performed for the five selected chemical compounds of Bauhinia scandens, found by UPLC-QTOF-MS By using Discover Studio 2020, UCSF Chimera, PyRx autodock vina and online tools. The MEBS and its fractions exhibited remarkable inhibition in dose dependant manner in the antinociceptive and antiinflammatory investigations. The antipyretic results of MEBS and DMBS were close to the standard drug indomethacin. Investigation of the thrombolytic effect of MEBS, CTBS, DMBS, and BTBS revealed notable clot-lytic potentials. Besides, the phenolic compounds of the plant extracts revealed strong binding affinity to the COX-1, COX-2, mPGES-1 and plasminogen activator enzymes. To recapitulate, based on the research work, Bauhinia scandens L. stem and its phytochemicals can be considered as prospective wellsprings for novel drug development and discovery by future researchers.

Abstract
Caesalpinia digyna (Rottl.) (Family: Fabaceae) is well known for its numerous medicinal values against several human disorders including fever, senile pruritis, diarrhea, tuberculosis, tonic disorder, diabetes, etc. The current study is intended to investigate the in vivo antipyretic activity of the methanol extract of C. digyna leaves (MECD) and its carbon-tetrachloride (CTCD) and butanol fraction (BTCD). Besides, in silico molecular docking and ADME/T profiling of the selective identified bioactive compounds of C. digyna has been also studied to validate the experimental outcomes and establish a better insight into the possible receptor-ligand interaction affinity. In vivo antipyretic activity of MECD, CTCD and BTCD were evaluated by employing yeast induced pyrexia technique in mice model and in silico analysis of the identified compounds of C. digyna has been implemented using PyRx autodock vina, Discovery Studio 2020, UCSF Chimera software and ADME/T online tools. MECD and BTCD unveiled significant antipyretic activity in dose dependent manner whereas, CTCD failed to exhibit significant antipyretic activity. Comparing to other test sample, MECD (400 mg/kg; b.w) (p < 0.001) displayed maximum inhibition of pyrexia. In molecular docking approach, docking score between −6.60 to −10.20 kcal/mol have been revealed. Besides, in ADME/T analysis, no compound violated the lipiniski’s 5 rules and displayed any toxicity. Biological and computational approaches ascertain the ethno-botanical use of C. digyna as a good agent against pyrexia and the compounds of C. digyna are primarily proved as safe. Hereafter, further analysis is suggested to validate this research.

Abstract
Lygodium microphyllum Cav. (Family: Lygodiaceae) is a perennial, snake fern and an invasive weed in Florida and also known as old world climbing fern. This study is intended to evaluate the antipyretic, analgesic, anti-inflammatory, antidiarrheal and anthelmintic activity of methanol extract of Lygodium microphyllum Cav. leaves (MELM) by in vivo, in vitro and in silico approaches. In addition, Biovia, PyRx autoDock Vina, UCSF Chimera have been applied to investigate the docking study in order to evaluate the binding interaction and an online tool was used to explore the ADME/T properties of selected bioactive compounds. In acetic acid induced writhing study, MELM inhibited 44.28% and 56.61% of writhes at 200 and 400 (mg/kg) respectively compared to standard drug Diclofenac-Na (10 mg/kg) (74.42% inhibition). In anti-inflammatory experiment by formalin triggered licking method, MELM caused significant (p < 0.05) inhibition of licking in both early phase (42.97%, 63.30%) and late phase (43.35%, 63.03%) at the doses of 200 and 400 mg/kg respectively, whereas reference drug Ibuprofen inhibited paw licking 77.18% in early phase and 76.86% in late phase. MELM also showed promising antipyretic potential where the maximum reduction of fever was produced by MELM 400 mg/kg whose fever lowering capacity is close to the prescribe drug Indomethacin 4 mg/kg, i.p. In Castor oil triggered diarrhea method, MELM delayed the onset time of diarrhea, continuous persistence of wet feces, and decreased the weight of wet feces remarkably. Defection inhibition was achieved 27.56% and 51.72%, for MELM 200 and at 400 (mg/kg) respectively while loperamide 2 (mg/kg) yields 55.17% inhibition of the diarrheal defecation. In anthelmintic bioassay, MELM took 5.83 ± 0.83 and 41.67 ± 1.78 min respectively for paralyzing and death compared to standard drug albendazole; (paralysis time 4.00 ± 0.73 min and death time 31,00 ± 1.71 min). Isoeleutherol, isoquercetin and quercetin were found prominent in molecular docking study and ADME/T analysis verified their drug likeliness. The research validates the moderate analgesic, anti-inflammatory, and remarkable antipyretic, antidiarrheal, anthelmintic activities of the plant extract which can be used an alternative source of novel therapeutics.

Abstract
Piper nigrum L. also called black pepper is popular for its numerous uses. The present research is designed to investigate the pharmacological potential of methanol extract of Piper nigrum (MEPN). The antidepressant investigation was performed by using both in vivo forced swimming test (FST) and tail suspension test (TST) methods while the anxiolytic research by hole-board test (HBT) method. Again, the antipyretic analysis was conducted through yeast-induced pyrexia method, whereas clot lysis activity was employed by the thrombolytic method. Furthermore, in silico studies followed by molecular docking analysis of several secondary metabolites, pass prediction, and ADME/T were evaluated with AutoDock Vina, Discovery Studio 2020, UCSF Chimera software PASS online, and ADME/T online tools. The plant extract demonstrated dose-dependent potentiality in antidepressant, anxiolytic, antipyretic, and thrombolytic activities. Induction of MEPN produced a significant (p < .5, p < .001) increase of mobility in FST and TST, and increased the head dipping and decreased the latency of time (p < .01, p < .001) in HBT. MEPN 400 (mg/kg; b.w.; p.o.) lowered the rectal temperature of yeast-induced pyrexia substantially (p < .001). Besides, MEPN produced promising (p < .001) clot lysis activity. In the computational approach, among all the proteins, a docking score was found ranging from -1.0 to -7.90 kcal/mol. Besides, all the compounds were found safe in ADME/T study. The results of our scientific research validate the suitability of this plant as an alternative source of novel therapeutics.

Abstract
Tetrastigma leucostaphylum (TL) is an important ethnic medicine of Bangladesh used to treat diarrhea and dysentery. Hence, current study has been designed to characterize the antidiarrheal (in vivo) and cytotoxic (in vitro) effects of T. leucostaphylum. A crude extract was prepared with methanol (MTL) and further partitioned into n-hexane (NTL), dichloromethane (DTL), and n-butanol (BTL) fractions. Antidiarrheal activity was investigated using castor oil induced diarrhea, enteropooling, and gastrointestinal transit models, while cytotoxicity was evaluated using the brine shrimp lethality bioassay. In antidiarrheal experiments, all doses (100, 200, and 400 mg/kg) of the DTL extract significantly reduced diarrheal stool frequency, volume and weight of intestinal contents, and gastrointestinal motility in mice. Similarly, in the cytotoxicity assay, all extracts exhibited activity, with the DTL extract the most potent (LC50 67.23 μg/mL). GC-MS analysis of the DTL extract identified 10 compounds, which showed good binding affinity toward M3 muscarinic acetylcholine, 5-HT3, Gut inhibitory phosphodiesterase, DNA polymerase III subunit alpha, and UDP-N-acetylglucosamine-1 carboxyvinyltransferase enzyme targets upon molecular docking analysis. Although ADME/T analyses predicted the drug-likeness and likely safety upon consumption of these bioactive compounds, significant toxicity concerns are evident due to the presence of the known phytotoxin, 2,4-di-tert-butylphenol. In summary, T. leucostaphylum showed promising activity, helping to rationalize the ethnomedicinal use and importance of this plant, its safety profile following both acute and chronic exposure warrants further investigation.

Abstract
An individual of Banded Lineblue Prosotas aluta was discovered in Bangladesh on 7 September 2018 from the Kaptai National Park, a mixed evergreen protected forest in the southeastern region of the country. The discovered species was found in the hill stream named ‘Boro Chara’. The photographic documentation confirms the certainty of the species. The occupancy of P. aluta in Asia and distribution around Bangladesh in Cachar and Khasi Hills of India indicate its existence but confirmation was wanting till date. Hence, we report the first confirmed record from Bangladesh.

Abstract
Thalassemia is one of the most common genetic diseases in the world. It is a major health problem, brings much morbidity, early mortality and a great deal of misery for a family both financially and emotionally. The patients suffering from beta thalassemia major do not survive for more than 5 years without blood transfusion. Blood transfusion is usually administered every two to five weeks to maintain the pre-transfusion hemoglobin level of 9-10 gm/dL. This study carried out in the department of Transfusion Medicine of Mymensingh Medical College Hospital from January 2014 to June 2014. A total of 200 parents were interviewed. There was a slight preponderance of females which accounted for 57.5% of the parents. Ninety seven (45.5%) had an income less than Rs. 5000 per month. Nearly 50% were illiterate with only 24.5% with a higher education. Consanguinity was positive in 72.5% of the parents with extended family history of thalassemia positive in 40.8%. Only 29.5% were immunized against Hepatitis B. Around 27.5% did not know whether they should be immunized. Fifty five percent of parents knew children should receive Dysferol. Twelve percent were aware of consanguinity to be a risk factor for thalassaemia with only 5% having undergone antenatal diagnosis. Parental knowledge about thalassemia and its preventive measures is inadequate; this requires intervention in the form of public health education programs concentrating on high risk/targeted population.

Abstract
Operative notes in surgical practice are a vital source of information and communication between healthcare professionals as well as being a legal document. Errors and omissions can have serious effects on patient care and lead to confusion. We audited our compliance within trauma and orthopaedics at a busy district general hospital in South East England with the standard set by the Royal College of Surgeons (England) before and after the introduction of an operation note template. We achieved significant improvements in compliance across almost all of the standard's domains and recommend widespread implementation of similar templates nationally.

Abstract
Suitable algorithms based on a combination of two or more simple rapid HIV assays have been shown to have a diagnostic accuracy comparable to double enzyme-linked immunosorbent assay (ELISA) or double ELISA with Western Blot strategies. The aims of this study were to evaluate the performance of five simple rapid HIV assays using whole blood samples from voluntary and replacement blood donors & HIV-infected patients (positive samples from BSMMU, Dhaka). Five rapid HIV assays: Determine™ HIV-1/2 (Inverness Medical), SD Bioline HIV 1/2 3.0 (Standard Diagnostics Inc.), First Response HIV Card 1-2.0 (PMC Medical India Pvt Ltd.), HIV1/2 Stat-Pak Dipstick (Chembio Diagnostic System, Inc) and Uni-Gold™ HIV-1/2 (Biotech) were evaluated between 1st February to 30th June, 2013 using 400 whole blood samples from voluntary and replacement blood donors. All samples that were reactive on all or any of the five rapid assays and 10% of non-reactive samples were tested on a confirmatory Inno-Lia HIV I/II immunoblot assay (Immunogenetics). Only 01 sample including ten positive samples from BSMMU were confirmed HIV-1 antibody positive, while 399 were HIV negative. The sensitivity at initial testing of Determine, SD Bioline and Uni-Gold™ was 100% (95% CI; 99.1-100) while First Response and Stat-Pak had sensitivity of 99.5% (95% CI; 98.2-99.9) and 97.7% (95% CI; 95.7-98.9) respectively, which increased to 100% (95% CI; 99.1-100) on repeat testing. The initial specificity of the Uni-Gold™ assay was 100% (95% CI; 99.6-100) while specificities were 99.6% (95% CI; 99-99.9), 99.4% (95% CI; 98.8-99.7), 99.6% (95% CI; 99-99.9) and 99.8% (95% CI; 99.3-99.9) for Determine, SD Bioline, First Response and Stat-Pak assays, respectively. There was no any sample which was concordantly false positive in Uni-Gold™, Determine and SD Bioline assays. An alternative confirmatory HIV testing strategy based on initial testing on either SD Bioline or Determine assays followed by testing of reactive samples on the Determine or SD Bioline gave 100% sensitivity (95% CI; 99.1-100) and 100% specificity (95% CI; 96-99.1) with Uni-Gold™ as tiebreaker for discordant results.

Abstract
Though regular blood transfusion improves the overall survival of patients with β-thalassemia which is one of the most common genetic diseases in the world, carries a definite risk of infection with blood-borne viruses. It is a major health problem, brings much morbidity, early mortality and a great deal of misery for a family both financially and emotionally. World Health Organization (WHO) reported that there is about 3% beta thalassemia carrier and more than two thousand thalassemic children are born every year in Bangladesh. We carried out this study to provide epidemiologic data on hepatitis B virus (HBV) & hepatitis C virus (HCV) infection among β-thalassemic patients. Moreover, HBV & HCV infection-associated risk factors were investigated in this study. Two hundred patients with β-thalassemia major were enrolled in this study. Using Rapid Immuno-chromatographic Test and their sera were tested for HBsAg and HCVAb. The positive HBsAg & HCVAb results were confirmed by ELISA. The study sample 200 consisted of 165 males (82.5%) and 35 females (17.5%), with a mean±SD age of 5.9±9.0 years. Four (2%) patients were HCV-Ab positive; 13(6.5%) were HBsAg positive. Univariate analysis showed that (P=0.01), older age (P=0.001), longer transfusion duration (P=0.000), HBsAg seropositivity (P=0.03), and higher serum ferritin level (P=0.002) were significantly associated with a higher prevalence of HCV. Using multivariate analysis, age (P<0.001), serum ferritin level (P< 0.001) were independent factors associated with HCV infection. Improvement of the people's knowledge about TTI risk factors, blood screening strategies and HBV vaccination have led to a dramatically decrease in prevalence of TTIs particularly HBV during the last decades in Bangladesh.However, post-transfusion transmission of HCV has still remained a major health concern in multi-transfused patients. As the prevalence of HCV infection is much higher among β-thalassemic patients as compared with HBV infections routine screening of donated blood for HCV is highly recommended by ELISA.

World Health Organization (WHO) reported that there is about 3% beta thalassemia carrier and more than two thousand thalassemic children are born every year in Bangladesh. Master Akib of age 15 years was the known case of Beta Thalassemia taking blood from his 3rd Birth Day from Mymensingh Combined Military Hospital, Bangladesh. Day care centre of Transfusion Medicine Department of Mymensingh Medical College Hospital started HBV, HCV, HIV screening of Thalassemic patient from 1st July, 2012. After screening of his blood, we found his blood contains HCV which is 3-4 times repeated positive with three other companies' reagent (rapid immuno-chromatographic assay) and result is confirmed. His treatment started and continues for 24 weeks and after 24 weeks, to monitor treatment response, his blood again test for Serum HCV-RNA which was not detected. Now Master Akib free from HCV infection and HCV diagnose accidentally because it remain silent for long time. We recommend that in public sector hospitals and health care units ELISA should be preferred for anti-HCV detection over ICT.

Abstract
Once Umbilical Cord with Placenta considered a biological waste product and generally discarded after delivery but now cord blood has emerged as a viable source of hematopoietic stem cell transplantation. High-risk premature infants require red cell transfusions for anemia. A unique property of cord blood (CB) for its high content of immature hematopoietic progenitor cells (HPCs). Placental blood for autologous transfusions can be collected with aseptic precaution/sterilely into citrate-phosphate-dextrose and stored at 4°C. During storage for 8 days, the placental red cell content of adenosine triphosphate remained normal. The 2,3,-diphosphoglycerate concentration of cells stored beyond 8 days declined sharply. So we have to store umbilical cord blood (UCB) within 7 days for its best result. During storage, placental blood underwent an exchange of extra-cellular Na+ and K+, but no change in glutathione content. Hemolysis was less than 1 percent. Bacteriologic and fungal cultures remained sterile. These suggest that human placental blood can be collected safely and preserved effectively for autologous/allogenic transfusion therapy. In neonatal transfusion practice, efforts have been made to provide premature infants with autologous red blood cell (RBC), especially those born before 32 gestational weeks. In India no adverse transfusion effects were seen in a wide variety of patients that received (pooled) allogeneic fresh whole blood / UCB transfusions. The use of UCB for small volume allogeneic transfusions in anaemic children in Africa or in malaria endemic areas has also been proposed. A preclinical study showed that donation and transfusion of UCB would be acceptable to women living in Mombasa, Kenya. In view of the small volumes RBC per unit that can be collected, it is most likely that anaemic children need of a small volume of transfusions. In resource-restricted countries would benefit most from this easily available transfusion product.

Abstract
Beta-thalassemia which is one of the most common genetic disorders in Bangladesh encompasses a group of monogemic diseases that have reduced synthesis or no synthesis of one or more globin chain of haemoglobin. The defects involved are extremely heterogenous and give rise to a large phenotypic spectrum with patients that are almost asymptomatic to cases in which regular blood transfusions are required to sustain life. The aim of the study is to estimate the frequency of beta thalassemia among the blood recipients in the Day Care Centre of Transfusion Medicine Department of Mymensingh Medical College Hospital from July, 2009 to June, 2010 along with their chelation habit. Retrospective cross-sectional study with the sample size of 784, clinical and family data was collected and descriptive statistics were done in the Laboratory of Transfusion Medicine Department. Among the 784 subjects, the beta thalassemia was 521 (66.46%), among the thalassemic patients only 59(11.32%) take injection Dysferrioxamine (Dysferol), the iron chelating agent. Male are predominant than female (63.53%). Those of the affected patients 67.18% were in age group 6 to 20 years. Although beta thalassemia is one of the first monogemic diseases and represents a global health problem, only recently has the scientific community started to focus on the real molecular mechanisms that underline this disease, opening new & exciting therapeutic perspectives for thalassemic patients worldwide. It is concluded from our study that availability of blood transfusion facilities along with an orally and cheaper iron chelator is an urgent need to ensure the management of needy thalassemic patients in Bangladesh.

Abstract
New developments in the epidemiology, treatment and prognosis of thalassemia have dramatically altered the approach to the care of affected patients. In the last 30 years, conventional treatment of β-thalassemia major, based primarily on regular blood transfusions and iron chelation therapy with desferrioxamine (DFO) has markedly improved the prognosis of the disease. Adequate administration of parenteral DFO reduces or prevents iron accumulation. The unavailability of DFO (dysferol) for most patients with thalassemia major and the failure of prescribed therapy to prevent complications in other patients have led to a search for alternative iron chelators; one of them, deferiprone (DFP) has been commercially available. Patients may ultimately benefit from having a choice between several chelators, including orally active drugs. Combination therapy and organ-targeted chelation, may soon have a considerable impact on the therapeutic outcome and quality of life of patients with thalassemia.

Abstract
Hepatitis B virus (HBV) and hepatitis C virus (HCV) infections are among the most frequent viral infections in humans, and represent a major global public health problem, especially in Asia. HBV- and HCV-related chronic hepatitis is the main causes of cirrhosis and hepatocellular carcinoma (HCC) of liver that are responsible for a high rate of morbidity and mortality. The study was done to analyze the prevalence of HBV and HCV among the people of Mymensingh City, Bangladesh. This cross sectional data was collected from the blood transfusion department of Mymensingh Medical College Hospital and descriptive analysis was performed. Out of 2015 participants, 126 were HBsAg positive and 45% were found HCV positive cases. Based on the results, it concludes that similar prevalence of HBV and HCV infections were seen in Bangladesh as other Asian countries.
