Abstract
Obesity and type 2 diabetes (DM) are risk factors for severe COVID-19 outcomes, which disproportionately affect South Asian populations. This study aims to investigate the humoral and cellular immune responses to SARS-CoV-2 in adult COVID-19 survivors with obesity and DM in Bangladesh. In this cross-sectional study, SARS-CoV-2-specific antibody and T cell responses were investigated in 63 healthy and 75 PCR-confirmed COVID-19 recovered individuals in Bangladesh, during the pre-vaccination first wave of the COVID-19 pandemic in 2020. In COVID-19 survivors, SARS-CoV-2 infection induced robust antibody and T cell responses, which correlated with disease severity. After adjusting for age, sex, DM status, disease severity, and time since onset of symptoms, obesity was associated with decreased neutralising antibody titers, and increased SARS-CoV-2 spike-specific IFN-γ response along with increased proliferation and IL-2 production by CD8+ T cells. In contrast, DM was not associated with SARS-CoV-2-specific antibody and T cell responses after adjustment for obesity and other confounders. Obesity is associated with lower neutralising antibody levels and higher T cell responses to SARS-CoV-2 post COVID-19 recovery, while antibody or T cell responses remain unaltered in DM.

Abstract
Wound healing is an intricate process of tissue regeneration that depends on the simultaneous presence of immunological and microenvironmental factors. The significant role of platelets and their granules in the wound-healing process has led to extensive research on their potential as a therapeutic intervention in different areas, including chronic wounds and aesthetic therapies. Saltwater aids in purification and promotes healing by utilizing osmosis. Sodium chloride, the chemical component present in salt, induces the extrusion of fluids from cells upon contact. If the liquids in issue are bacterial, they will also be ejected, assisting in the cleansing of the skin. Desiccation, often known as the drying out of injured cells, is well-known for its antibacterial properties and subsequent ability to reduce inflammation. This case series aims to investigate the advantages of using saltwater dressing following platelet-rich plasma therapy for chronic wounds.

Abstract
In Bangladesh, body soaps are very popular among consumers due to their flavors and low alkali content. The current study assesses the contamination of several trace metals (TMs) such as iron (Fe), copper (Cu), zinc (Zn), chromium (Cr), manganese (Mn), nickel (Ni), cadmium (Cd), and lead (Pb) in some of the body soaps most commonly used in Bangladesh. The concentrations of Fe, Cu, Zn, Cr, and Mn were found within the acceptable limits stipulated by the World Health Organization (WHO); however, in contrast, the concentrations of Ni, Cd, and Pb remained below the detection limit. Notably, the concentration of Cr in two soap samples (S-2, S-3) out of twenty-one soap samples exceeded the permissible limit stipulated by the WHO. Health risks associated with the TM intake via dermal routes were evaluated in terms of chronic daily intake (CDI) and hazard quotient (HQ). The results indicated that no non-carcinogenic risks (NCR) are likely to occur owing to the use of those body soaps. The carcinogenic risk (CR) estimated for Cr revealed no possibility of probable carcinogenic diseases. Though the NCR and CR are unlikely to occur resulting from the long-term uses of these soaps, the present study provides baseline information on the possible contaminations of TMs in the beauty soaps that do not seem to have been reported so far in Bangladesh. In light of the above information, it can be concluded that the presence of TMs in the body soaps could be a warning for people in general thereby suggesting continuous monitoring.

Abstract
Steam, dry heat, radiation, ethylene oxide gas, evaporated hydrogen peroxide, and many other sterilization methods are used to sanitize medical equipment (e.g., chlorine dioxide gas, nitrogen dioxide, and vaporized peracetic acid). The benefits of ethylene oxide (EO) are its great processing capabilities, high ionic conductivity, high flexibility, low cost, and exceptional adhesive qualities. Patients on hemodialysis, those undergoing extracorporeal photopheresis, and plasmapheresis donors have all reported allergic reactions to EO. Differentiating between IgE-mediated anaphylaxis and anaphylactoid reactions is often impossible in practice due to the wide range of clinical symptoms. The infrequency of EO reactions coupled with healthcare personnel's lack of familiarity with this clinical phenomenon may result in their underdiagnosis. We describe the case of a platelet donor who developed an allergy, while donating at a transfusion facility, due to an ethylene oxide-sterilized apheretic kit. We aim to draw attention to the fact that care should be given while handling cases of this nature as they can become life-threatening.

Abstract
INTRODUCTION Mesenchymal stem cell (MSC) therapy appeared promising in knee osteoarthritis (OA). We examined if a single intra-articular (IA) autologous total stromal cells (TSC) and platelet-rich plasma (PRP) injection improved knee pain, physical function, and articular cartilage thickness in knee OA. METHODS The study was performed in the physical medicine and rehabilitation department of Bangabandhu Shaikh Mujib Medical University, Dhaka, Bangladesh. Knee OA was diagnosed according to the American College of Rheumatology criteria and randomly assigned to treatment (received TSC and PRP) and control groups. Kallgreen-Lawrance (KL) scoring system was used to grade primary knee OA. The Visual Analogue Scale (VAS, 0-10 cm) for pain, WOMAC (Western Ontario and McMaster Universities Arthritis Index) for physical function, and medial femoral condylar cartilage (MFC) thickness (millimeters) under ultrasonogram (US) were documented and compared between groups before and after treatment. Statistical Package analyzed data for Social Scientists (SPSS 22.0; IBM Corp, Armonk, NY) was used for data analysis. Pre- and post-intervention outcomes were measured using the Wilcoxon-sign test, whereas Mann-Whitney U-test calculated the difference between groups; a p-value <0.05 was considered statistically significant. Result: In the treatment group, 15 received IA-TSC and PRP preparation, and in the control group, 15 patients received no injection, but quadricep muscle-strengthening exercise. There was no significant difference between groups regarding VAS for pain, WOMAC physical function, and cartilage thickness before starting the treatment and two weeks after intervention. VAS for pain and WOMAC physical function scores improved profoundly in the treatment group after 12 and 24 weeks of intervention; the pain and physical function scores difference between groups was also significant. However, significant mean femoral cartilage thickness was not changed until the end of 24 weeks (U=175.00, p=0.009 two-tailed and U= 130.00, p=0.016 two-tailed, respectively, for right and left knee). CONCLUSION Single TSC and PRP injection reduces knee pain and improves physical function and cartilage thickness in knee OA. While pain and physical function improvement happen earlier, cartilage thickness change takes more time.

Abstract
BackgroundWhile patient-reported outcome measures (PROMs) are widely recommended in clinical care, their application is limited [1]. The RADAI-F5 is a validated PROM to determine RA foot disease activity [2]. Patients’ and clinicians’ perceptions of the RADAI-F5’s clinical utility have yet to be captured.ObjectivesThis study aims to explore patient and clinician opinions and perceptions of the clinical utility of the RADAI- F5’s in managing rheumatoid foot disease.MethodsA 60-minute semi-structured interview using video conference calls with adult RA patients and rheumatologists, physiotherapists, and podiatrists was conducted as part of the interpretive phenomenological analysis research. The interviews included open-ended questions about the effect of foot disease, current clinical utilization of PROMS, and barriers and facilitators to the clinical application of the RADAI-F5. Inductive thematic data analysis with Nvivo12 identified emerging themes.ResultsEight participants with rheumatoid arthritis: seven females; mean [standard deviation, SD] age 52.4 [9.5] years; mean [SD] disease duration 16.1 [16.4] years; eight clinicians; mean [SD] age 46.75 [5.3] years; mean [SD] years of clinical experience 19.5 [2.21] years. Four main themes were identified (Table 1); ‘Feet are a priority’ as the impact of RA on the feet was substantial and had a negative impact on quality of life. The second theme was ‘Need for a clinically feasible foot PROM’ as clinicians and patients recognised the lack of a clinically feasible tool that can determine RA foot disease. The third emerging theme was ‘RADAI-F5 facilitators’ as the tool can promote communication, guide management, help screen foot symptoms, monitor foot disease status and treatments longitudinally, and promote patient education. The final theme was ‘RADAI-F5 barriers’ as there were associated practical difficulties, including lack of appointment time, administrative burdens associated with PROM use, lack of trust in the RADAI-F5’s validity and IT barriers since there is no universal electronic system for reporting RADAI-F5 results.Table 1.Themes with respective quotes that emerged as part of the individual interviews to understand the clinical utility of the RADAI-F5ThemeQuotationsTheme 1: Feet are important“Foot disease is common and it’s troublesome for patients” (C16) “I couldn’t see my friends because I was always so tired and in pain. It is very lonely.” (P07)Theme 2: Existing methods for measuring foot disease activity are inadequate“The feet are under-represented in the clinical tools for assessing disease activity, and clinicians don’t look at feet enough.” (C11)“We’ve tried numerous PROMS. Historically, I think probably it’s time-consuming for our clinical consultation”. (C12)Theme 3: RADAI-F5 facilitators“I think [The RADAI-F5] improves the clinician-patient relationship” (C15)“Using the RADAI-F5 could measure the success of the treatments that we are implicating.” (C12)Theme 4: RADAI-F5 barriers“I mean, this (RADAI-F5) will obviously go along with other tools. You know, the blood tests and things as well.” (P01)ConclusionThe RADAI-F5 has significant potential as a therapeutic tool to aid in managing foot disease in RA. However, several implementation barriers need to be overcome before widespread use in rheumatology clinics can occur.References[1]Muradin I, van der Heide HJ.

Abstract
PURPOSE The aim of the study was to assess the antibody response to the ChAdOx1-nCoV vaccine in individuals who were not previously infected by COVID-19. PATIENTS AND METHODS All people aged 18-65 years who received their first vaccination with ChAdOx1-nCoV from March to May 2021 were approached for inclusion. Individuals with sufficient antibody titers against SARS-CoV-2 infection before vaccination were considered previously infected and were excluded from the analysis. We observed viral spike protein RBD-S1-specific IgG antibody levels at day 28 of the first dose of vaccination and day 14 of the second dose of vaccination (74 days from index vaccination). An optical density ratio (ODR) of >1.1 was considered to have a positive antibody response, 0.8 to 1.1 borderline and <0.8 was denoted as negative. Informed consent was ensured before enrollment, and ethical principles conformed with the current Declaration of Helsinki. RESULTS This observational study comprised 769 infection-naïve individuals (mean age 40.5 years, 38.9% female). Spike-specific IgG antibody responses elicited after the first and second doses of vaccine were 99.9% and 100%, respectively. The median ODR was 5.43 (interquartile range [IQR]: 4.32-6.98) and 10.90 (IQR 9.02-11.90) after the first and second doses. Higher age was associated with lower antibody levels after both dosages. However, no sex-specific variation was seen. People with comorbidity had a lower antibody level after the second dose. Tenderness (51.46%) and fever (19.30%) were the most common local and systemic side effects after vaccination. CONCLUSION This study was one of the earlier attempts in the country to assess the antibody response to ChAdOx1-nCoV vaccine recipients. The results imply that general people should be encouraged to take the vaccine at their earliest.

Abstract
BACKGROUND Convalescent plasma has been widely used to treat COVID-19 and is under investigation in numerous randomized clinical trials, but results are publicly available only for a small number of trials. The objective of this study was to assess the benefits of convalescent plasma treatment compared to placebo or no treatment and all-cause mortality in patients with COVID-19, using data from all available randomized clinical trials, including unpublished and ongoing trials (Open Science Framework, https://doi.org/10.17605/OSF.IO/GEHFX ). METHODS In this collaborative systematic review and meta-analysis, clinical trial registries (ClinicalTrials.gov, WHO International Clinical Trials Registry Platform), the Cochrane COVID-19 register, the LOVE database, and PubMed were searched until April 8, 2021. Investigators of trials registered by March 1, 2021, without published results were contacted via email. Eligible were ongoing, discontinued and completed randomized clinical trials that compared convalescent plasma with placebo or no treatment in COVID-19 patients, regardless of setting or treatment schedule. Aggregated mortality data were extracted from publications or provided by investigators of unpublished trials and combined using the Hartung-Knapp-Sidik-Jonkman random effects model. We investigated the contribution of unpublished trials to the overall evidence. RESULTS A total of 16,477 patients were included in 33 trials (20 unpublished with 3190 patients, 13 published with 13,287 patients). 32 trials enrolled only hospitalized patients (including 3 with only intensive care unit patients). Risk of bias was low for 29/33 trials. Of 8495 patients who received convalescent plasma, 1997 died (23%), and of 7982 control patients, 1952 died (24%). The combined risk ratio for all-cause mortality was 0.97 (95% confidence interval: 0.92; 1.02) with between-study heterogeneity not beyond chance (I2 = 0%). The RECOVERY trial had 69.8% and the unpublished evidence 25.3% of the weight in the meta-analysis. CONCLUSIONS Convalescent plasma treatment of patients with COVID-19 did not reduce all-cause mortality. These results provide strong evidence that convalescent plasma treatment for patients with COVID-19 should not be used outside of randomized trials. Evidence synthesis from collaborations among trial investigators can inform both evidence generation and evidence application in patient care.

Abstract
From the beginning of corona virus disease 19(COVID-19) pandemic, there has been concern how to protect vulnerable group like pregnant women from severe acute respiratory syndrome corona virus 2(SARS-CoV-2). Historically, pregnant women experiences increased mortality during any pandemic situation. Pregnant women show almost the similar clinical features as that of non-pregnant adults with COVID-19 infection. Different systematic reviews have begun to focus light on pregnancy outcomes in COVID-19 patients, but knowledge is very limited and still the basis is case series and individual experiences. Apart from the scientifically proven therapeutic options used in COVID-19 such as steroid, low molecular weight heparin, the role of convalescent plasma therapy (CPT) has never been evaluated. We present a case of a pregnant woman of 32 weeks of conception, treated with CPT with favourable outcome in a private hospital of Dhaka, Bangladesh.

Abstract
Poultry production has boomed in Bangladesh in recent years. The poultry sector has contributed significantly to meet the increased demand for animal source proteins in the country. However, increased use of antimicrobials appeared to be a significant threat to food safety in the poultry sector. The poultry drug and feed sellers are at the frontline position involving selecting and delivering the antimicrobials to the poultry farmers. Studies assessing the poultry drug and feed sellers’ knowledge, attitudes, and practices (KAPs) are limited. The current study aimed to assess the community poultry drug and feed sellers’ KAPs of antimicrobial use (AMU) and antimicrobial resistance (AMR) in some selected areas of Bangladesh. We determined the respondents’ (drug and the feed sellers) KAPs of AMU and AMR using a tested and paper-based questionnaire. The study demonstrated that most respondents have insufficient knowledge, less positive attitudes, and inappropriate practices regarding AMU and AMR. The factor score analysis further showed that the type of respondents and their years of experience, level of education, and training on the drug were the significant factors impacting the current knowledge, attitudes, and practices of AMU and AMR. The adjusted logistic regression analysis revealed that the drug sellers who completed their education up to 12th grade and had training on the drug had adequate knowledge of AMU and AMR. The data also showed that the drug sellers belong to the age group 31–35 and 36–40 years and who completed 12th grade had good attitudes on the same. Likewise, the analysis further determined that drug sellers belonging to the age category 18–25 and 26–30 years, and interestingly, the respondents who completed education up to 12th grade, had better practices. Spearman’s rank-order correlation revealed a positive association between each pair of the KAPs scores for the respondents. The correlation was fair between knowledge–attitudes, knowledge–practices, and attitudes–practices. Based on the current study results, we recommend educational interventions and appropriate training for the poultry drug and feed sellers to raise awareness and to upgrade their current knowledge on the appropriate use of antimicrobials. This will ultimately lead to reducing the chances of developing AMR in the poultry sectors of the country.

Abstract
Objectives General: To assess the safety, efficacy and dose response of convalescent plasma (CP) transfusion in severe COVID-19 patients Specific: a. To identify the appropriate effective dose of CP therapy in severe patients b. To identify the efficacy of the therapy with their end point based on clinical improvement within seven days of treatment or until discharge whichever is later and in-hospital mortality c. To assess the clinical improvement after CP transfusion in severe COVID-19 patients d. To assess the laboratory improvement after CP transfusion in severe COVID-19 patients Trial Design This is a multicentre, multi-arm phase II Randomised Controlled Trial. Participants Age and sex matched COVID-19 positive (by RT-PCR) severe cases will be enrolled in this trial. Severe case is defined by the World Health Organization (W.H.O) clinical case definition. The inclusion criteria are 1. Respiratory rate > 30 breaths/min; PLUS 2. Severe respiratory distress; or SpO2 ≤ 88% on room air or PaO2/FiO2≤ 300 mm of Hg, PLUS 3. Radiological (X-ray or CT scan) evidence of bilateral lung infiltrate, AND OR 4. Systolic BP < 90 mm of Hg or diastolic BP <60 mm of Hg. AND/OR 5. Criteria 1 to 4 AND or patient in ventilator support Patients’ below18 years, pregnant and lactating women, previous history of allergic reaction to plasma, patients who have already received plasma from a different source will be excluded. Patients will be enrolled at Bangabandhu Sheikh Mujib Medical University (BSMMU) hospital, Dhaka medical college hospital (DMCH) and Mugda medical college hospital (MuMCH). Apheretic plasma will be collected at the transfusion medicine department of SHNIBPS hospital, ELISA antibody titre will be done at BSMMU and CMBT and neutralizing antibody titre will be checked in collaboration with the University of Oxford. Patients who have recovered from COVID-19 will be recruited as donors of CP. The recovery criteria are normality of body temperature for more than 3 days, resolution of respiratory symptoms, two consecutively negative results of sputum SARS-CoV-2 by RT-PCR assay (at least 24 hours apart) 22 to 35 days of post onset period, and neutralizing antibody titre ≥ 1:160. Intervention and comparator This RCT consists of three arms, a. standard care, b. standard care and 200 ml CP and c. standard care and 400 ml CP. Patients will receive plasma as a single transfusion. Intervention arms will be compared to the standard care arm. Main outcomes The primary outcome will be time to clinical improvement within seven days of treatment or until discharge whichever is later and in-hospital mortality. The secondary outcome would be improvement of laboratory parameters after therapy (neutrophil, lymphocyte ratio, CRP, serum ferritin, SGPT, SGOT, serum creatinine and radiology), length of hospital stay, length of ICU stay, reduction in proportion of deaths, requirement of ventilator and duration of oxygen and ventilator support. Randomisation Randomization will be done by someone not associated with the care or assessment of the patients by means of a computer generated random number table using an allocation ratio of 1:1:1. Blinding (masking) This is an open level study; neither the physician nor the patients will be blinded. However, the primary and secondary outcome (oxygen saturations, PaO2/FiO2, BP, day specific laboratory tests) will be recorded using an objective automated method; the study staff will not be able to influence the recording of these data. Number to be randomised (sample size) No similar study has been performed previously. Therefore no data are available that could be used to generate a sample size calculation. This phase II study is required to provide some initial data on efficacy and safety that will allow design of a larger study. The trial will recruit 60 participants (20 in each arm). Trial Status Protocol version 1.4 dated May 5, 2020 and amended version 1.5, dated June 16, 2020. First case was recruited on May 27, 2020. By August 10, 2020, the trial had recruited one-third (21 out of 60) of the participants. The recruitment is expected to finish by October 31, 2020. Trial registration Clinicaltrials.gov ID: NCT04403477. Registered 26 May, 2020 Full Protocol The full protocol is attached as an additional file, accessible from the Trial’s website (Additional file 1). In the interest in expediting dissemination of this material, the familiar formatting has been eliminated; this letter serves as a summary of the key elements of the full protocol.

Abstract
Sub clinical hypothyroidism (SCH) is common in clinical practice. Autoimmunity is thought to be the most important cause of SCH. In this cross-sectional study, we investigated 120 SCH patients and 100 healthy controls attending the Endocrinology Outpatient Department of Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, Bangladesh from June 2014 to April 2015 for anti-thyroid antibodies (anti-TPO and anti-Tg). Measurement of serum TSH, FT4, anti-TPO, and anti-Tg antibodies were done by using the chemiluminescent sequential immunometric assay. SCH patients had a higher mean age; the frequencies of female subjects, those having family history of thyroid disease or other autoimmune diseases, and goiter were higher in SCH group than in the control group. Forty-five percent (45%) of SCH patients were positive for anti-thyroid antibodies (23.3% for both anti-TPO and anti-Tg, 16.7% for only anti-TPO, and 5% positive for only anti-Tg) in comparison to only 10% anti-thyroid antibody positive controls (none for both antibodies, 8% for only anti-TPO, and 2% positive for only anti-Tg). The SCH subjects in the lower age group, females and with a TSH >10μIU/mL had the higher frequency of thyroid autoimmunity. Female gender, high socioeconomic condition, the presence of other autoimmune diseases, the presence of goiter and TSH >10μIU/mL were associated with higher odds of anti-thyroid antibody positivity in the SCH group, though none were statistically significant. The frequency of anti-thyroid antibody was higher in SCH and was more prevalent among the females, younger patients and those having a goiter, other autoimmune diseases, and TSH >10μIU/mL.

Abstract
Aims and objectives To assess the safety and efficacy of stem cell therapy in patients with cirrhosis of the liver (LC) in the context of developing country with limited facilities for cell-based therapy and advanced technologies. Materials and methods A total of 34 patients received granulocyte colony-stimulating factor at a dose of 30 IU, daily for 2 to 11 days to upregulate the numbers of white blood cells and stem cells. Subsequently, stem cells were isolated from the peripheral blood of LC patients in a closed chamber using a harvesting machine. Variable amounts of autologous stem cells were injected to LC patients for once. The patients were followed for 3 months and various factors related to safety and parameters of efficacy were analyzed in this interim report. Results Out of 34 patients available for final analysis, 3 months after the start of stem therapy, 4 patients died within this period. There was no significant alteration in biochemical parameters due to stem cell therapy, and patients also did not develop any features of acute liver failure indicating that short-term safety parameters of stem cell therapy may be acceptable. Stem cell therapy had a dominant effect on ascites of in this cohort. Although 24 of 34 patients had ascites at the start of therapy,ascites were found in 11 patients after one month and only 4 patients had ascites after 3 months. The positive role of stem cell therapy on ascites in LC patients may be attributed, even in part, to increased serum levels of albumin after therapy compared to basal levels (p <0.001). Conclusion This first study about stem cell therapy in Bangladesh indicates that cell therapy may be accomplished in general hospitals of developing countries if the proper design and mild to moderate types of invasive approach is utilized. The apparent safety of administered stem cells in LC patients and the observed effect on ascites of LC patients inspire optimism about the installation of new and innovative therapy in Bangladesh. Future studies with phase I/II may with stem cell and others cell may be planned at Bangladesh in patients with LC and other intractable diseases with suitable control arms.How to cite this article: Mahtab MA, Akbar SMF, Begum M, Islam MA, Rahim MA, Noor-E-Alam SM, Alam MA, Khondaker FA, Moben AL, Mohsena M, Khan SI, Huq MZ, Munshi S, Hoque A, Haque SA.

Abstract
Pediatric myocardium is unique from mature myocardium; thus, the use of adult cardioplegia for pediatric cardiac operations may provide suboptimal myocardial protection. It is found that children undergoing heart surgery show evidence of less myocardial damage when del Nido cardioplegia is used instead of a standard cardioplegic solution. Del Nido cardioplegia solution provides a depolarized hyperkalaemic arrest lasting up to 60 minutes, reduces spontaneous and inducible activity during arrest, and prevents hyper contraction during early reperfusion. In this single blind randomized trial, a total of 60 patients underwent intra cardiac repair for TOF in National Institute of Cardiovascular Diseases, Dhaka, Bangladesh from July 2014 to January 2016 fulfilling inclusion and exclusion criteria. They were randomly assigned in two groups- 30 patients in Del Nido group (Group A) and 30 patients in standard group (Group B). Comparison between groups was done by Chi square test and Student's test. All data were analyzed by SPSS 20.0 for windows. P value less than 0.05 was considered as significant. There was statistically significant difference among the patients in terms of mean total initial cardioplegia volume, mean number of additional dose, mean additional dose amount, mean cross clamp time, mean CPB time (331.67±188.07 vs. 458.67±226.62, p=0.022; 0.13±0.35 vs. 1.27±0.89, p=0.000; 23.33±60.76 vs. 336.83±259.6, p=0.000; 45.10±10.35 vs. 59.23±23.21, p=0.003; 89.30±15.73 vs. 111.10±29.23, p=0.001 respectively). Mean post operative serum troponin I level at arrival in ICU and after 24 hours between two groups were statistically significantly different (55.60±32.91 vs. 83.5±58.99; p=0.024 and 13.01±5.84 vs. 18.16±9.51; p=0.014 respectively). The mean ventilation duration, mean ICU stay were also statistically significant. This study showed that cardiac arrest with Del Nido cardioplegia during intra cardiac repair for TOF was associated with improved myocardial protection over standard cardioplegia in terms of reduced CPB and cross clamp times, lower total volume of cardioplegia.

Abstract
BACKGROUND Prostate cancer is highly influenced by androgens and genes. The authors investigated whether genetic polymorphisms along the androgen biosynthesis and metabolism pathways are associated with androgen concentrations or with the risk of prostate cancer or high-grade disease from finasteride treatment. METHODS A nested case-control study from the Prostate Cancer Prevention Trial using data from men who had biopsy-proven prostate cancer (cases) and a group of biopsy-negative, frequency-matched controls was conducted to investigate the association of 51 single nucleotide polymorphisms (SNPs) in 12 genes of the androgen pathway with overall (total), low-grade, and high-grade prostate cancer incidence and serum hormone concentrations. RESULTS There were significant associations of genetic polymorphisms in steroid 5α-reductase 1 (SRD5A1) (reference SNPs: rs3736316, rs3822430, rs1560149, rs248797, and rs472402) and SRD5A2 (rs2300700) with the risk of high-grade prostate cancer in the placebo arm of the Prostate Cancer Prevention Trial; 2 SNPs were significantly associated with an increased risk (SRD5A1 rs472402 [odds ratio, 1.70; 95% confidence interval, 1.05-2.75; Ptrend = .03] and SRD5A2 rs2300700 [odds ratio, 1.94; 95% confidence interval, 1.19-3.18; Ptrend = .01]). Eleven SNPs in SRD5A1, SRD5A2, cytochrome P450 family 1, subfamily B, polypeptide 1 (CYP1B1), and CYP3A4 were associated with modifying the mean concentrations of serum androgen and sex hormone-binding globulin; and 2 SNPs (SRD5A1 rs824811 and CYP1B1 rs10012; Ptrend < .05) consistently and significantly altered all androgen concentrations. Several SNPs (SRD5A1 rs3822430, SRD5A2 rs2300700, CYP3A43 rs800672, and CYP19 rs700519; Ptrend < .05) were significantly associated with both circulating hormone levels and prostate cancer risk. CONCLUSIONS Germline genetic variations of androgen-related pathway genes are associated with serum androgen concentrations and the risk of prostate cancer. Further studies to examine the functional consequence of novel causal variants are warranted. Cancer 2016;122:2332-2340. © 2016 American Cancer Society.

Abstract
OBJECTIVE In the Prostate Cancer Prevention Trial (PCPT), finasteride reduced the risk of prostate cancer by 25%, even though high-grade prostate cancer was more common in the finasteride group. However, it remains to be determined whether finasteride concentrations may affect prostate cancer risk. In this study, we examined the association between serum finasteride concentrations and the risk of prostate cancer in the treatment arm of the PCPT and determined factors involved in modifying drug concentrations. METHODS Data for this nested case-control study are from the PCPT. Cases were drawn from men with biopsy-proven prostate cancer and matched controls. Finasteride concentrations were measured using a liquid chromatography-mass spectrometry validated assay. The association of serum finasteride concentrations with prostate cancer risk was determined by logistic regression. We also examine whether polymorphisms in the enzyme target and metabolism genes of finasteride are related to drug concentrations using linear regression. RESULTS AND CONCLUSIONS Among men with detectable finasteride concentrations, there was no association between finasteride concentrations and prostate cancer risk, low-grade or high-grade, when finasteride concentration was analyzed as a continuous variable or categorized by cutoff points. Since there was no concentration-dependent effect on prostate cancer, any exposure to finasteride intake may reduce prostate cancer risk. Of the twenty-seven SNPs assessed in the enzyme target and metabolism pathway, five SNPs in two genes, CYP3A4 (rs2242480; rs4646437; rs4986910), and CYP3A5 (rs15524; rs776746) were significantly associated with modifying finasteride concentrations. These results suggest that finasteride exposure may reduce prostate cancer risk and finasteride concentrations are affected by genetic variations in genes responsible for altering its metabolism pathway.

Abstract
OBJECTIVE To evaluate the effect of finasteride on serum androst-4-ene-3,17-dione (androstenedione) and its association with prostate cancer risk among subjects who participated in the Prostate Cancer Prevention Trial. METHODS We analyzed serum androstenedione levels in 317 prostate cancer cases and 353 controls, nested in the Prostate Cancer Prevention Trial, a randomized placebo-controlled trial that found finasteride decreased prostate cancer risk. Androstenedione is the second most important circulating androgen in men besides testosterone and also a substrate for 5α-reductase enzyme. RESULTS We observed a 22% increase in androstenedione levels compared with the baseline values in subjects who were treated with finasteride for 3 years. This significant increase did not vary by case-control status. Adjusted odds ratio and 95% confidence interval for the third tertile of absolute change in androstenedione levels compared with the first tertile were 0.42 (95% confidence interval, 0.19-0.94) for low-grade (Gleason score <7) cases. Similar results were observed when analyzed using percent change. There were no significant associations between serum androstenedione levels and the risk of high-grade disease. CONCLUSION The results of this nested case-control study confirm that finasteride blocks the conversion of testosterone to dihydrotestosterone (DHT) and of androstenedione to 5α-androstanedione-3,17-dione, which also leads to the reduction of DHT formation. This decrease in DHT may help reduce the risk of low-grade prostate cancer in men. Our data on a differential effect of androstenedione also suggest that some high-grade prostate cancers may not require androgen for progression.

Abstract
BACKGROUND Chronic inflammation is hypothesized to influence prostate cancer development, although a definitive link has not been established. METHODS Prostate cancer cases (N = 191) detected on a for-cause (clinically indicated) or end-of-study (protocol directed) biopsy, and frequency-matched controls (N = 209), defined as negative for cancer on an end-of-study biopsy, were sampled from the placebo arm of the Prostate Cancer Prevention Trial. Inflammation prevalence and extent in benign areas of biopsy cores were visually assessed using digital images of hematoxylin and eosin-stained sections. Logistic regression was used to estimate associations. RESULTS Of note, 86.2% of cases and 78.2% of controls had at least one biopsy core (of three assessed) with inflammation in benign areas, most of which was chronic. Men who had at least one biopsy core with inflammation had 1.78 [95% confidence interval (CI), 1.04-3.06] times the odds of prostate cancer compared with men who had zero cores with inflammation. The association was stronger for high-grade disease (Gleason sum 7-10, N = 94; OR, 2.24; 95% CI, 1.06-4.71). These patterns were present when restricting to cases and controls in whom intraprostatic inflammation was the least likely to have influenced biopsy recommendation because their prostate-specific antigen (PSA) was low (<2 ng/mL at biopsy). CONCLUSION Inflammation, most of which was chronic, was common in benign prostate tissue, and was positively associated with prostate cancer, especially high grade. The association did not seem to be due to detection bias. IMPACT This study supports an etiologic link between inflammation and prostate carcinogenesis, and suggests an avenue for prevention by mitigating intraprostatic inflammation.

Abstract
Esophageal adenocarcinoma is increasing in the US and Western countries and frequent gastresophageal reflux or gastresophageal reflux disease carrying gastric acid and bile acid could contribute to esophageal adenocarcinogenesis. This study was designed to detect the expression of gastric acid-inducing gene Na + /H + exchanger-1 (NHE-1) ex vivo and then to explore targeting of NHE-1 expression or activity to control esophageal cancer cell viability in vitro and in nude mouse xenografts. The data showed that NHE-1 was highly expressed in esophageal adenocarcinoma tissues (66 of 101 cases [65.3%], but not in normal esophageal squamous cell epithelium (1 of 26 cases [3.8%]). Knockdown of NHE-1 expression using NHE-1 shRNA or inhibition of NHE-1 activity using the NHE-1 inhibitor amiloride suppressed viability and induced apoptosis in esophageal cancer cells. Molecularly, amiloride inhibited expression of cyclooxygenase-2 and matrix metallopeptidase-9 but not NHE-1 mRNA in esophageal cancer cells. A combination of amiloride and guggulsterone (a natural bile acid receptor inhibitor) showed more than additive effects in suppressing esophageal cancer cell growth in vitro and in nude mouse xenografts. This study suggests that inhibition of NHE-1 expression or activity or combination of amiloride and guggulsterone could be useful in control of esophageal adenocarcinoma.

Abstract
BACKGROUND Gastroesophageal reflux is a risk factor for esophageal adenocarcinoma, and bile acid and its farnesoid X receptor (FXR) have been implicated in esophageal tumorigenesis. The authors investigated the role of FXR expression and activity in esophageal cancer initiation and growth. METHODS FXR expression in esophageal adenocarcinoma tissues was assessed by immunohistochemistry. Knockdown of FXR expression in esophageal cancer cells in vitro and in nude mice xenografts was suppressed by FXR small hairpin RNA (shRNA) and guggulsterone (a natural FXR inhibitor). Esophageal cancer cells were treated with bile acids to demonstrate their effects on growth-promoting genes. RESULTS FXR was expressed in 48 of 59 esophageal adenocarcinoma tissues (81.3%), and this overexpression was associated with higher tumor grade, larger tumor size, and lymph node metastasis; however, was inversely associated with retinoic acid receptor-β2 (RAR-β2 ) expression. Knockdown of FXR expression suppressed tumor cell growth in vitro and in nude mouse xenografts. Guggulsterone reduced the viability of esophageal cancer cells in a time-dependent and dose-dependent manner, whereas this effect was diminished after knockdown of FXR expression. Guggulsterone induced apoptosis through activation of caspase-8, caspase-9, and caspase-3 in tumor cells. FXR mediated bile acid-induced alterations of gene expression, eg, RAR-β2 and cyclooxygenase-2 (COX-2). CONCLUSIONS Inhibition of FXR by FXR shRNA or guggulsterone suppressed tumor cell viability and induced apoptosis in vitro, and it reduced tumor formation and growth in nude mouse xenografts. FXR also mediated bile acid-induced alterations of cell growth-related genes in esophageal cancer cells.

Abstract
The role of the insulin-like growth factor (IGF) axis and whether IGFs interact with androgen-suppressing agents in relation to prostate carcinogenesis is unclear. This nested case-control study (n = 1,652 cases/1,543 controls) examined whether serum IGF1, IGF2, IGFBP2, IGFBP3, and the IGF1:IGFBP3 ratio were associated with prostate cancer in the Prostate Cancer Prevention Trial (PCPT), a randomized, placebo-controlled trial of finasteride for prostate cancer prevention. Presence or absence of cancer was determined by prostate biopsy. Baseline serum was assayed for IGF-axis analytes using ELISA. Logistic regression estimated ORs and 95% confidence intervals for risk of total, low-grade (Gleason 2-6) and high-grade (Gleason 7-10) cancers. Results were stratified by intervention assignment. In both the placebo and finasteride arms, serum IGF1, IGF2, IGFBP3, and the IGF1:IGFBP3 ratio were not associated with prostate cancer. However, men in the highest versus lowest quartile of serum IGFBP2 had a 48% (P(trend) = 0.02) and 55% (P(trend) = 0.01) increased risk for total and low-grade cancers, respectively. These IGFBP2 associations were attenuated and no longer statistically significant in the finasteride arm. Our results suggest that in general, serum IGF-axis analytes were not associated with prostate cancer risk in the PCPT in which presence or absence of all cancers was biopsy-determined. The exception was the finding that high serum IGFBP2 is a risk factor for low-grade disease, which was attenuated for men on finasteride. Further research is needed to understand better the risk incurred by high IGFBP2 and whether androgen-suppressing agents such as finasteride influence aspects of IGFBP2 physiology relevant to prostate carcinogenesis.

Abstract
BACKGROUND Finasteride, an inhibitor of 5α-reductase (type II), lowers intraprostatic dihydrotestosterone (DHT), which is reflected in serum as reduced 5α-androstane-3α,17β-diol glucuronide (3α-dG). It also modestly increases serum testosterone (T), estrone (E(1)), and estradiol (E(2)). In this altered hormonal milieu, it is unknown whether serum concentrations of these hormones are associated with prostate cancer risk. METHODS In this nested case-control study of men in the finasteride arm of the Prostate Cancer Prevention Trial, sex steroid hormones and sex hormone binding globulin were measured at baseline and approximately 3-year posttreatment in 553 prostate cancer cases and 694 controls. RESULTS Median posttreatment changes in concentrations of 3α-dG, T, E(1), and E(2) were -73.8%, +10.1%, +11.2%, and +7.5% (all P < 0.001), respectively. Neither the pre- nor posttreatment concentrations of 3α-dG, nor its change, were associated with risk. Pretreatment, high concentrations of E(1) and low concentrations of T were associated with increased cancer risk [OR; 95% confidence interval (CI) quartile 4 vs. 1: 1.38 (0.99-1.93) P(trend) = 0.03; 0.64 (0.43-0.93) P(trend) = 0.07, respectively]. Posttreatment, high concentrations of both E(1) and E(2) were associated with increased cancer risk [OR; 95% CI quartile 4 vs. 1: 1.54 (1.09-2.17) P(trend) = 0.03; 1.49 (1.07-2.07) P(trend) = 0.02, respectively]. CONCLUSIONS Among finasteride-treated men, concentrations of 3α-dG were not associated with total or Gleason grades 2 to 6, 7 to 10, or 8 to 10 cancer. High serum estrogens may increase cancer risk when intraprostatic DHT is pharmacologically lowered. IMPACT Low posttreatment serum estrogens may identify men more likely to benefit from use of finasteride to prevent prostate cancer.

Abstract
The main objective of this study was to investigate the prevalence of bla (NDM-1) in Gram-negative bacteria in Bangladesh. In October 2010 at the International Centre for Diarrhoeal Disease Research, Bangladesh (ICDDR,B) laboratories, 1,816 consecutive clinical samples were tested for imipenem-resistant Gram-negative organisms. Imipenem-resistant isolates were tested for the bla (NDM-1) gene. Among 403 isolates, 14 (3.5 %) were positive for bla (NDM-1), and the predominant species were Klebsiella pneumoniae, Acinetobacter baumannii, and Escherichia coli. All bla (NDM-1)-positive isolates were resistant to multiple antibiotics. Among β-lactamase genes, bla (CTX-M-1-group) was detected in ten isolates (eight bla (CTX-M-15)), bla (OXA-1-group) in six, bla (TEM) in nine, bla (SHV) in seven, and bla (VIM) and bla (CMY) in two isolates each. The 16S rRNA methylase gene, armA, was detected in five K. pneumoniae isolates and in one E. coli isolate. rmtB and rmtC were detected in a Citrobacter freundii and two K. pneumoniae isolates, respectively. qnr genes were detected in two K. pneumoniae isolates (one qnrB and one qnrS) and in an E. coli isolate (qnrA). Transferable plasmids (60-100 MDa) carrying bla (NDM-1) were detected in 7 of the 11 plasmid-containing isolates. Pulsed-field gel electrophoresis (PFGE) analysis grouped K. pneumoniae isolates into three clusters, while E. coli isolates differed significantly from each other. This study reports that approximately 3.5 % of Gram-negative clinical isolates in Bangladesh are NDM-1-producing.

Abstract
Number of elderly persons gradually increased in Bangladesh due to improved health awareness and health care. Age is the single most important risk factor for stroke. This study aims at finding the prevalence of stroke in a Bangladeshi population aged forty years and above. The cases of stroke were ascertained in two phases of door-to-door survey. In phase-I, trained interviewers performed face-to-face interview with subjects for the detection stroke cases using the World Health Organization (WHO) screening protocol for neurological diseases. In phase-II, subjects suspected to have a stroke underwent a clinical evaluation for diagnosis or exclusion of stroke by a neurological team. The study involved 15627 participants aged 40 years and above. A total of 47 participants found to have stroke, expressing an overall prevalence rate of 3.00 per 1000 (95% CI 0.95 to 2.45). Prevalence of stroke were 2.0, 3.0, 2.0, 10.0, and 10.0 per 1000 within age groups of 40-49 years, 50-59 years, 60-69 years, 70-79 years and 80 years and above age group respectively. Prevalence of stroke in people with age range 70-79 years compared to 40-49 years age range is 4.988 (95% CI 2.309 to 10.77) times and people with age range ≥80 years compared to 40-49 years age range is 4.798 (95% CI 1.597 to14.416) times. Prevalence was higher among men in comparison with women. The male: female ratio is 3.44:2.41 per 1000 respectively. Bangladeshi male populations in rural areas are found to have stroke more than urban people. A large community based study should be undertaken to further confirm the result of this present study.

Abstract
Abstract
Incidence of esophageal adenocarcinoma is increasing in the United States and other Western countries. Frequent gastroesophageal reflux or gastroesophageal reflux disease, resulting in Barrett esophagus, may be responsible for the increase. The main function of bile acid is to facilitate the formation of micelles for promotion of the processing and absorption of dietary fat. As surfactants or detergents, bile acids are potentially toxic to the cells, so their concentrations in the small intestine are tightly regulated. However, patients with frequent gastroesophageal reflux will have reflux damage caused by acid and bile acid-containing juice in the distal esophagus, with the result that normal squamous cells around the gastroesophageal junction will change to a new cell phenotype (incomplete intestinal metaplasia), because this type of cell is more resistant to acid and bile-caused injuries; therefore, Barrett esophagus is formed. This study aimed to determine the tumor-promoting effects of bile acid on esophageal cancer cells and the underlying molecular mechanisms. The data showed that different bile acids (i.e., chenodeoxycholic acid, deoxycholic acid, and lithocholic acid) induced COX-2 but inhibited RAR-β2 expression through farnesoid X receptor (FXR) expression in esophageal cancer cell lines. FXR is a nuclear receptor for bile acids functioning as a signaling molecule in the liver and the intestines and frequent gastroesophageal reflux induces FXR expression in esophageal cells. Indeed, the ex vivo data demonstrated that FXR was highly expressed in esophageal adenocarcinoma (81%) tissues and was associated with reduced RAR-β2 expression. Knockdown of FXR expression using FXR shRNA antagonized the effects of bile acid in gene expression and suppressed tumor cell viability in vitro and in nude mouse xenografts. Moreover, guggulsterone, a FXR inhibitor, was able to reduce the viability of esophageal cancer cells in time- and dose-dependent manner in vitro. Apoptosis induced by guggulsterone was through activation of caspase 8, 9, and 3. In conclusion, suppression of FXR expression using FXR shRNA or its inhibitor guggulsterone was able to suppress tumor cell growth in vitro and in vivo and induce apoptosis in vitro. This study demonstrated that inhibition of FXR could be further evaluated as a target in prevention of esophageal adenocarcinoma.

Abstract
The etiology of prostate cancer remains elusive, although steroid hormones probably play a role. Considering the carcinogenic potential of estrogen metabolites as well as altered intraprostatic estrogen biosynthesis during the development of prostate cancer, we investigated associations between repeat polymorphisms of three key estrogen-related genes (CYP11A1, CYP19A1, UGT1A1) and risk of prostate cancer in the Prostate Cancer Prevention Trial (PCPT), designed to test finasteride versus placebo as a chemoprevention agent. Using data and specimens from 1154 cases and 1351 controls who were frequency matched on age, family history of prostate cancer and PCPT treatment arm, we used logistic regression to estimate odds ratios (ORs) and 95% confidence intervals (95% CIs) separately in the placebo and finasteride arms. Among men in the placebo arm, CYP19A1 7/8 genotype carriers had a significantly higher risk of prostate cancer compared with those with the 7/7 genotype (OR = 1.70, 95% CI = 1.16-2.5), regardless of Gleason grade. This genotype was also associated with elevated serum estrogen levels. For the (TA)(n) repeat polymorphism in UGT1A1, the heterozygous short (<7 repeats)/long (≥7 repeats) genotype was significantly associated with the risk of low-grade prostate cancer (OR = 1.34, 95% CI = 1.05-1.70) compared with the short/short genotype. No significant association was found with CYP11A1. These associations were not observed among men in the finasteride arm. The results indicate that repeat polymorphisms in genes involved in estrogen biosynthesis and metabolism may influence risk of prostate cancer but that their effects may be modified by factors altering hormone metabolism, such as finasteride treatment.

Abstract
Objective Finasteride reduces prostate cancer risk by blocking the conversion of testosterone to dihydrotestosterone. However, whether finasteride affects estrogens levels or change in estrogens affects prostate cancer risk is unknown. Methods These questions were investigated in a case–control study nested within the prostate cancer prevention trial (PCPT) with 1,798 biopsy-proven prostate cancer cases and 1,798 matched controls. Results Among men on placebo, no relationship of serum estrogens with risk of prostate cancer was found. Among those on finasteride, those in the highest quartile of baseline estrogen levels had a moderately increased risk of Gleason score < 7 prostate cancer (for estrone, odds ratio [OR] = 1.51, 95% confidence interval [CI] = 1.06–2.15; for estradiol, OR = 1.50, 95% CI = 1.03–2.18). Finasteride treatment increased serum estrogen concentrations; however, these changes were not associated with prostate cancer risk. Conclusion Our findings confirm those from previous studies that there are no associations of serum estrogen with prostate cancer risk in untreated men. In addition, finasteride results in a modest increase in serum estrogen levels, which are not related to prostate cancer risk. Whether finasteride is less effective in men with high serum estrogens, or finasteride interacts with estrogen to increase cancer risk, is uncertain and warrants further investigation.

Abstract
Large clinical trials provide a tremendous opportunity to integrate correlative, comprehensive biological studies with invaluable repositories of biospecimens and clinical and other data from the trial. The Prostate Cancer Prevention Trial (PCPT) was a phase III randomized, double-blind, placebo-controlled clinical trial of finasteride in 18,882 men. Clinical data and blood and tissue specimens were collected at baseline and throughout the study, offering an opportunity to create a program project to investigate hypotheses related to the biology underlying the PCPT findings as well as the etiology and risk of prostate cancer. The transition of the randomized PCPT into this translational and epidemiologic scientific investigation required extensive planning and coordination. Five individual but interrelated projects were brought together with the underlying program theme of the genetic, metabolic, and environmental factors associated with the risks of overall and high-grade prostate cancer and how these factors affected the efficacy of finasteride in preventing cancer. All projects with serum-based measures use a single, shared, nested case-control sample of participants so that each subject provides a more complete biomarker and genetic profile for the evaluation of joint effects of these factors. Strengths of this program include the following: 1) the control group contains only men who are negative for biopsy-detected cancer, 2) the statistical methods to evaluate associations of risk factors with disease are shared across all projects, 3) the large number of cancer cases with fully characterized genetic, metabolic, and behavioral exposures, 4) a central pathology core histopathologically classified the prostate cancer, and 5) cancer cases identified during the PCPT reflect the characteristics of cases currently being detected in the prostate-specific antigen screening era, leading to contemporary and highly relevant results. This article describes the comprehensive methodology and multidisciplinary collaborations, both national and international, essential to a major risk-modeling research program. We provide a framework for doing collaborative research in an international setting structured around a common theme of a clinical trial.

Abstract
Altered microRNA (miRNA) expression has been found to promote carcinogenesis, but little is known about the role of miRNAs in esophageal cancer. In this study, we selected 10 miRNAs and analyzed their expression in 10 esophageal cancer cell lines and 158 tissue specimens using Northern blotting and in situ hybridization, respectively. We found that Let-7g, miR-21 and miR-195p were expressed in all 10 cell lines, miR-9 and miR-20a were not expressed in any of the cell lines, and miR-16-2, miR-30e, miR-34a, miR-126 and miR-200a were expressed in some of the cell lines but not others. In addition, transient transfection of miR-34a inhibited c-Met and cyclin D1 expression and esophageal cancer cell proliferation, whereas miR-16-2 suppressed RAR-β(2) expression and increased tumor cell proliferation. Furthermore, we found that miR-126 expression was associated with tumor cell dedifferentiation and lymph node metastasis, miR-16-2 was associated with lymph node metastasis, and miR-195p was associated with higher pathologic disease stages in patients with esophageal adenocarcinoma. Kaplan-Meier analysis showed that miR-16-2 expression and miR-30e expression were associated with shorter overall and disease-free survival in all esophageal cancer patients. In addition, miR-16-2, miR-30e and miR-200a expression were associated with shorter overall and disease-free survival in patients with esophageal adenocarcinoma; however, miR-16-2, miR-30e and miR-200a expression were not associated with overall or disease-free survival in squamous cell carcinoma patients. Our data indicate that further evaluation of miR-30e and miR-16-2 as prognostic biomarkers is warranted in patients with esophageal adenocarcinoma. In addition, the role of miR-34a in esophageal cancer also warrants further study.

Abstract
PURPOSE We investigated the association between the length of the polymorphic trinucleotide CAG microsatellite repeats in exon 1 of the AR gene and the risk of prostate cancer. MATERIALS AND METHODS This is a nested case-control study of 1,159 cases and 1,353 controls from the Prostate Cancer Prevention Trial, a randomized, placebo controlled trial testing whether the 5α-reductase inhibitor finasteride could decrease the 7-year prevalence of prostate cancer. During the course of the trial men underwent annual digital rectal examination and prostate specific antigen measurement. Prostate biopsy was recommended in all men with abnormal digital rectal examination or finasteride adjusted prostate specific antigen greater than 4.0 ng/ml. Cases were drawn from men with biopsy determined prostate cancer identified by for cause or end of study biopsy. Controls were selected from men who completed the end of study biopsy. RESULTS Mean CAG repeat length did not differ between cases and controls. The frequency distribution of cases and controls for the AR CAG repeat length was similar. There were no significant associations of CAG repeat length with prostate cancer risk when stratified by treatment arm (finasteride or placebo), or when combined. There was also no significant association between CAG repeat length and the risk of low or high grade prostate cancer. CONCLUSIONS There is no association of AR CAG repeat length with prostate cancer risk. Knowledge of AR CAG repeat length provides no clinically useful information to predict prostate cancer risk.

Abstract
Abstract
In our previous studies, we have demonstrated that expression of retinoid receptor-induced gene 1 (RRIG1) was significantly reduced in different human cancers and that restoration of RRIG1 expression suppressed tumor cell growth in vitro and in vivo. In prostate cancer, we have showed that PC3 cells do not express RRIG1 but 22RV1 express high levels of RRIG1 mRNA. In this study, we first analyzed RRIG1 expression in prostate cancer tissue specimens and then transfected RRIG1 cDNA into PC3 cells and RRIG1 antisense cDNA into 22RV1 cells to restore or knockdown RRIG1 expression in these cells, respectively. We found that expression of RRIG1 protein was significantly downregulated in prostate cancer tissues compared to the normal tissues. Moreover, stably RRIG1-transfected prostate cancer cells grew much slower than that of the controls, whereas the antisense RRIG1-transfected 22RV1 cells grew faster than that of the controls. After that, we assessed the ability of migration and invasion of these stable cells using Boyden chamber assay and found that RRIG1 transfection reduced tumor cell migration and invasion in PC3 cells compared to the control transfections. In contrast, the antisense RRIG1 transfection promoted the tumor cell migration and invasion in 22RV1 cells. Molecularly, we found that RRIG1 was binding to Src protein and suppressed Src phosphorylation as well as RhoA activation. Consequently, RRIG1 reduced expression of phosphorylated Erk1/2 and AKT as well as expression of c-Jun, COX-2, and cyclinD1. The results from the current study demonstrated a tumor-suppressive effect of RRIG1 in prostate cancer, suggesting that RRIG1 gene may play a role in suppressing prostate tumorigenesis and progression.

Abstract
Epilepsy occurs in 30 to 40% of individuals with autism spectrum disorder (ASD). However the association of epilepsy or abnormal electroencephalogram is not known in our population. This study addresses the incidence of epilepsy and or abnormal electroencephalogram in Bangladeshi children with autism spectrum disorder. The clinical history and electroencephalogram of 18 children diagnosed with autism spectrum disorder were retrospectively reviewed. Forty four percent were diagnosed with epilepsy or abnormal electroencephalogram. This abnormal electroencephalogram or epilepsy occurred at significantly higher rates in children with more impaired range of autism spectrum disorder. These finding suggest that the use of neurological investigative technique such as electroencephalogram (EEG) should be considered routinely in children with autism spectrum disorder especially in more impaired individuals.

Abstract
To evaluate the role of oxidative stress in prostate cancer risk, we analyzed serum levels of protein carbonyl groups in 1,808 prostate cancer cases and 1,805 controls, nested in the Prostate Cancer Prevention Trial, a randomized, placebo-controlled trial that found finasteride decreased prostate cancer risk. There were no significant differences in protein carbonyl levels in baseline samples between those later diagnosed with prostate cancer and those without at the end of study biopsy. Adjusted odds ratios and 95% confidence intervals (95% CI) for the 4th quartile of protein carbonyl level for the combined, placebo, and finasteride arms were 1.03 (95% CI, 0.85-1.24), 0.88 (95% CI, 0.69-1.12), and 1.27 (95% CI, 0.94-1.71), respectively. There were no significant associations between carbonyl level and risk when analyzing high-grade and low-grade disease separately, nor did finasteride affect protein oxidation levels. The results of this large nested case-control study do not support the hypothesis that oxidative stress, at least as measured by protein carbonyl level, plays a role in prostate cancer.

Abstract
Hyperinsulinemia and obesity-related metabolic disturbances are common and have been associated with increased cancer risk and poor prognosis. To investigate this issue in relation to prostate cancer, we conducted a nested case-control study within the Prostate Cancer Prevention Trial (PCPT), a randomized, placebo-controlled trial testing finasteride versus placebo for primary prevention of prostate cancer. Cases (n = 1,803) and controls (n = 1,797) were matched on age, PCPT treatment arm, and family history of prostate cancer; controls included all eligible non-whites. Baseline bloods were assayed for serum C-peptide (marker of insulin secretion) and leptin (an adipokine) using ELISA. All outcomes were biopsy determined. Logistic regression calculated odds ratios (OR) for total prostate cancer and polytomous logistic regression calculated ORs for low-grade (Gleason <7) and high-grade (Gleason >7) disease. Results were stratified by PCPT treatment arm for C-peptide. For men on placebo, higher versus lower serum C-peptide was associated with a nearly 2-fold increased risk of high-grade prostate cancer (Gleason >7; multivariate-adjusted OR, 1.88; 95% confidence interval, 1.19-2.97; P(trend) = 0.004). When C-peptide was modeled as a continuous variable, every unit increase in log(C-peptide) resulted in a 39% increased risk of high-grade disease (P = 0.01). In contrast, there was no significant relationship between C-peptide and high-grade prostate cancer among men receiving finasteride. Leptin was not independently associated with high-grade prostate cancer. In conclusion, these results support findings from other observational studies that high serum C-peptide and insulin resistance, but not leptin, are associated with increased risk of high-grade prostate cancer. Our novel finding is that the C-peptide-associated risk was attenuated by use of finasteride.

Abstract
BACKGROUND Data on long-term intra-individual variability in high-sensitivity C-reactive protein (hsCRP) are needed to determine whether one measurement adequately reflects usual levels in prospective studies of on the etiology of cancer and other chronic diseases; when not reflective, the ability to statistically detect modest to moderate associations is reduced. The authors estimated the size of this source of variability and consequent attenuation of the relative risk (RR). METHODS High-sensitivity C-reactive protein (hsCRP) concentration was measured using a high-sensitivity immunoturbidometric assay in sera collected at years 2, 4, and 6 from 50 men in the placebo arm of the Prostate Cancer Prevention Trial (PCPT). After natural logarithm-transformation of hsCRP, analysis of variance was used to estimate the within- and between-individual variances from which the intra-class correlation coefficient (ICC) was calculated. RESULTS The observed RR due to an ICC < 1 was calculated by e((ln true RR*ICC)) for a range of true RRs. The 4-year ICC was 0.66. Measuring hsCRP once and assuming no other error, if the true RRs were 1.50, 2.00, and 3.00 when comparing high with low concentration, then the observed RRs would be 1.31, 1.58, and 2.06, respectively. CONCLUSION Investigators planning to measure hsCRP only once should design adequately sized studies to preserve inferences for hypothesized modest to moderate RRs.

Abstract
The creation of single nucleotide polymorphism (SNP) databases (such as NCBI dbSNP) has facilitated scientific research in many fields. SNP discovery and detection has improved to the extent that there are over 17 million human reference (rs) SNPs reported to date (Build 129 of dbSNP). SNP databases are unfortunately not always complete and/or accurate. In fact, half of the reported SNPs are still only candidate SNPs and are not validated in a population. We describe the identification of SNDs (single nucleotide differences) in humans, that may contaminate the dbSNP database. These SNDs, reported as real SNPs in the database, do not exist as such, but are merely artifacts due to the presence of a paralogue (highly similar duplicated) sequence in the genome. Using sequencing we showed how SNDs could originate in two paralogous genes and evaluated samples from a population of 100 individuals for the presence/absence of SNPs. Moreover, using bioinformatics, we predicted as many as 8.32% of the biallelic, coding SNPs in the dbSNP database to be SNDs. Our identification of SNDs in the database will allow researchers to not only select truly informative SNPs for association studies, but also aid in determining accurate SNP genotypes and haplotypes.

Abstract
Retinoic acid receptor-beta2 (RAR-beta2) is a putative tumor suppressor gene in various cancers. To determine the underlying molecular mechanisms, we transfected RAR-beta2 cDNA into esophageal cancer TE-1 and TE-8 cells and found that RAR-beta2 suppressed tumor cell growth in vitro and tumor formation in nude mice in TE-8 cells, whereas the stable transfection of RAR-beta2 did not restore retinoid sensitivity or inhibit tumor formation in nude mouse in TE-1 cells. Molecularly, we revealed that RAR-beta2 antitumor activity was associated with expression and suppression of cyclooxygenase-2 (COX-2) in these tumor cell lines. Moreover, antisense RAR-beta2 cDNA induced COX-2 expression in TE-3 cells. Furthermore, when COX-2 expression is first blocked by using antisense COX-2 expression vector, the effect of RAR-beta2 is diminished in these tumor cells. In addition, we analyzed expression of RAR-beta2 and COX-2 mRNA in tissue specimens and found that RAR-beta2 expression is associated with low levels of COX-2 expression in esophageal cancer tissues. Induction of RAR-beta2 expression in oral leukoplakia tissues after the patients treated with 13-cis RA correlated with a reduction in COX-2 expression and clinical response. Our findings indicate that some of RAR-beta2 antitumor activities are mediated by suppression of COX-2 expression in some of these esophageal cancer cells. After correlating antitumor effect of RAR-beta2 with COX-2 expression in the published studies, we also found the association. Thus, further studies will determine whether manipulation of COX-2 expression in different cancers can antagonize RAR-beta2 activity.

Abstract
Statins are a class of low molecular weight drugs that inhibit the rate-limiting enzyme of the mevalonate pathway 3-hydroxy-3-methylglutaryl-CoA reductase. Statins have been approved and effectively used to control hypercholesterolemia in clinical setting. Recent study showed statin's antitumor activity and suggested a potential role for prevention of human cancers. In this study, we did cell viability, DNA fragmentation, and terminal deoxynucleotidyl transferase-mediated dUTP nick-end labeling assays to evaluate the action of statins on prostate cancer cells and used Western blotting and RhoA activation assay to investigate the underlying molecular mechanism of action. Our data showed that lovastatin and simvastatin effectively decreased cell viability in three prostate cancer cell lines (PC3, DU145, and LnCap) by inducing apoptosis and cell growth arrest at G(1) phase. Both lovastatin and simvastatin induced activation of caspase-8, caspase-3, and, to a lesser extent, caspase-9. Both statins suppressed expression of Rb, phosphorylated Rb, cyclin D1, cyclin D3, CDK4, and CDK6, but induced p21 and p27 expression in prostate cancer cells. Furthermore, lovastatin and simvastatin suppressed RhoA activation and c-JUN expression, but not cyclooxygenase-2 expression. Our data showed that the antitumor activity of statins is due to induction of apoptosis and cell growth arrest. The underlying molecular mechanism of statin's action is mediated through inactivation of RhoA, which in turn induces caspase enzymatic activity and/or G(1) cell cycle. Future studies should focus on examining statins and other apoptosis-inducing drugs (e.g., cyclooxygenase-2 inhibitors or curcumin) together to assess their efficacy in prevention of prostate cancer.

Abstract
OBJECTIVES Deoxyribonucleic acid (DNA) extraction from blood and genotyping for candidate single nucleotide polymorphisms (SNP) is now an important part of almost all molecular epidemiologic studies. However, in many studies the amount of blood sample is limited or only serum is available. We conducted several pilot studies to identify methods for DNA extraction and high-throughput SNP genotyping of both white blood cell (WBC) and serum DNA that can be done centrally and reliably for large numbers of samples. METHODS We used biospecimens from the Prostate Cancer Prevention Trial (PCPT), a phase III, double-blind, placebo-controlled trial that tested the efficacy of finasteride for the primary prevention of prostate cancer. DNA was extracted from WBCs, from serum, and also from serum after organic solvent extraction for analysis of hormones. We also conducted blinded high-throughput genotyping in three laboratories to assess feasibility and reliability of results with differing methodologies using DNA from WBCs and from serum. RESULTS Genotyping of DNA extracted from WBCs resulted in highly reliable, reproducible results across laboratories using different genotyping platforms. However, genotyping with DNA extracted from serum did not provide reliable data using high-throughput multiplex approaches such as Sequenom (hME and iPLEX) and Applied Biosystems SNPlex, but was successful using Taqman. CONCLUSIONS Based on the results of these pilot studies, we conclude that DNA obtained from serum must be used judiciously, and that genotyping using multiplex methods is not suitable for serum DNA.

Abstract
We previously showed that induction of retinoid receptor-induced gene-1 (RRIG1) expression inhibited RhoA activation and tumor cell colony formation, invasion, and proliferation, and these effects are associated with the suppression of extracellular signal-regulated protein kinases 1 and 2 phosphorylation and cyclooxygenase-2 expression. To further elucidate its role in tumor cell growth, gene expression, and tumorigenesis, we determined RRIG1 expression in breast and esophageal tissue specimens and then stably transfected RRIG1 into a TE-8 esophageal squamous cell carcinoma (SCC) cell line. We found that RRIG1 was expressed in normal mammary glands (10 of 10) but not all ductal carcinoma in situ [11 of 19 (57.9%), P = 0.018] and invasive cancer [14 of 30 (46.7%), P = 0.0023] tissues. Similarly, RRIG1 was expressed in normal esophageal epithelium (22 of 22) but not all dysplastic [6 of 43 (14%), P = 0.0001] and SCC [50 of 122 (41%), P = 0.0001] tissues. Furthermore, RRIG1 expression correlated positively with tumor differentiation but inversely with lymph node metastasis of esophageal SCC. Finally, the stable transfection of RRIG1 inhibited esophageal SCC cell growth and the expression of extracellular signal-regulated protein kinases 1 and 2 and cell cycle-related genes (e.g., cyclin D1, phosphorylated Rb, and E2F). RRIG1-transfected sublines also inhibited tumor development in nude mice. The results of this study indicate that RRIG1 plays a role in suppressing tumorigenesis.

Abstract
AbstractRepair of damage to DNA resulting from chemotherapy may influence drug toxicity and survival in response to treatment. We evaluated the role of polymorphisms in DNA repair genes APE1, XRCC1, ERCC1, XPD, and XRCC3 in predicting therapeutic outcomes of older adults with acute myeloid leukemia (AML) from 2 Southwest Oncology Group (SWOG) clinical trials. All patients received standard chemotherapy induction regimens. Using logistic and proportional hazards regression models, relationships between genotypes, haplotypes, and toxicities, response to induction therapy, and overall survival were evaluated. Patients with XPD Gln751C/Asp312G (‘D’) haplotype were more likely to have complete response (OR = 3.06; 95% CI, 1.44-6.70) and less likely to have resistant disease (OR = 0.32; 95%CI, 0.14-0.72) than patients with other haplotypes. ERCC1 polymorphisms were significantly associated with lung (P = .037) and metabolic (P = .041) toxicities, and patients with the XRCC3 241Met variant had reduced risk of liver toxicity (OR = 0.32; 95%CI, 0.11-0.95). Significant associations with other toxicities were also found for variant XPD genotypes/haplotypes. These data from clinical trials of older patients treated for AML indicate that variants in DNA repair pathways may have an impact on both outcomes of patients and toxicities associated with treatments. With validation of results in larger samples, these findings could lead to optimizing individual chemotherapy options.

Abstract
Focal atrophy is extremely common in prostate specimens. Although there are distinct histologic variants, the terminology is currently nonstandardized and no formal classification has been tested for interobserver reliability. This lack of standardization hampers the ability to study the biologic and clinical significance of these lesions. After informal and formal meetings by a number of the authors, focal atrophy lesions were categorized into 4 distinct subtypes as follows: (i) simple atrophy, (ii) simple atrophy with cyst formation, (iii) postatrophic hyperplasia, and (iv) partial atrophy. In phase 1 of the study, pathologists with varying levels of experience in prostate pathology were invited to view via the Internet a set of "training" images with associated descriptions of lesions considered typical of each subtype. In phase 2 of the study, each participant provided diagnoses on a series of 140 distinct "test" images that were viewed over the Internet. These test images consisted of the 4 subtypes of atrophy and images of normal epithelium, high grade prostatic intraepithelial neoplasia, and carcinoma. The diagnoses for each image from each pathologist were compared with a set of "standard" diagnoses and the kappa statistic was computed. Thirty-four pathologists completed both phases of the study. The interobserver reliability (median kappa) for classification of lesions as normal, cancer, prostatic intraepithelial neoplasia, or focal atrophy was 0.97. The median kappa for the classification of atrophy lesions into the 4 subtypes was 0.80. The median percent agreement with the standard diagnosis for the atrophy subtypes were: simple 60.6%, simple with cyst formation 100%; postatrophic hyperplasia 87.5%; partial atrophy 93.9%. The lower percentage for simple atrophy reflected a propensity to diagnose some of these as simple atrophy with cyst formation. Seven pathologists completed the phase 2 analysis a second time, and their intraobserver reproducibility was excellent. Three of 4 pathologists with low agreement with the standard diagnosis for simple atrophy improved their scores after repeating the analysis after re-examination of the "training set" of images. In conclusion, these criteria for variants of focal prostate atrophy may facilitate studies to examine the relation between various patterns of prostate atrophy and prostate cancer.
