Acute coronary syndrome (ACS), a life-threatening manifestation of coronary artery disease, ranges from unstable angina (UA) to acute myocardial infarction (AMI). To reduce the morbidity and mortality resulting from acute coronary syndrome, we should have to find out some predictor or prognostic indicator. A prognostic indicator should be available at the time of initial patient’s evaluation, in order to maximize the potential benefits of early risk assessment. This study designed to evaluate plasma BNP as a prognostic tool in patients with acute coronary syndrome. A prognostic cohort study was carried out with 90 (ninety) acute coronary syndrome patients on the basis of their clinical and laboratory criteria with age range of 30 to 90 years in the department of biochemistry, BSMMU, in collaboration with department of cardiology, NICVD, BSMMU and BIRDEM. Plasma BNP concentrations were measured on enrollment and then grouping of the study subjects were done on the basis of their empirical cut off value of plasma BNP concentration. All the patients were free from heart failure, renal disease, thyroid disease and hepatic disorder. Main outcomes were mortality, morbidity and survival after hospital discharge with or without any disability. All the subjects were categorized into two and to see the significance between two groups in relation to age and sex Unpaired –t test and Chi square test were done. Finally, Binary logistic regression was done. Among 90 acute coronary syndromes patients, there were 74(82.2%) male and 16(17.8%) female with mean age of the study population 51.8 years and the age range of 30 t0 90 years. Among enrolled patients, 24 (26.7%) were NSTEMI and 66 (73.3%) were STEMI that includes 29 (32.2%) anterior MI, 21 (23.3%) inferior MI, 16 (17.8%) other varieties of MI. All the study subjects were grouped into two on the basis of empirical cut off value of plasma BNP 640pg/ml on enrollment. Group I with plasma BNP level less than 640pg/ml includes 57 (63.3%) subjects and group II with plasma BNP more than 640pg/ml includes 33 (36.7%) subjects. Among group I (n=57) good recovery, morbidity and mortality found to be in 41(71.9%), 15(26.3%) and 1(1.8%) patients and those in group II (n=33) found in 6(18.2%), 19(57.6%) and 8(24.2%) patients respectively. Keeping the group I in reference category binary logistic regression analysis done, showing odds ratio 11.5 with p- value 0.000. The odds ratio 11.5 indicates that there is 11.5 times higher chance of getting bad outcome in ACS patients having higher plasma BNP concentrations. Bangladesh Med J. 2017 May; 46 (2): 32-37

Background: B-type Natriuretic Peptide (BNP) a neurohormone synthesized in ventricular myocardium and released into the circulation in response to ventricular dilatation and pressure overload, is a current biomarker used for identifying patients at high risk of Acute Coronary Syndrome (ACS). High level of BNP is associated with an increased risk of Major Adverse Cardiac Events (MACE) including new or progressive heart failure and myocardial infarction. The objective of this study was to assess the prognosis of newly diagnosed ACS patients by using plasma BNP level. Methods: This study was conducted in the department of Biochemistry, Bangabandhu Sheikh Mujib Medical University (BSMMU) in collaboration with National Institute of Cardiovascular Disease (NICVD) from January 2013 to December 2013. Total 100 newly diagnosed ACS patients, aged 30 to 70 years, irrespective of sex who reported within 24 hours of onset of symptoms were enrolled in this study by purposive and convenient sampling. Plasma BNP level of selected study subjects was measured within 24 hours of onset of symptoms. Then subjects were grouped on the basis of their empirical cut-off value of plasma BNP concentration Group I having plasma BNP level <135 pg/mL and Group II having plasma BNP level 135 pg/mL. Results: Of 100 ACS patients, 86 were male and 14 were female with the mean age 49.61±10.28 years and the age range of 30 to 70 years. Among 26 patients in Group I, good recovery, morbidity and mortality were 22 (84.6%), 4 (15.4%) and zero and among 74 patients in Group II good recovery, morbidity and mortality were 18 (24.3%), 53 (71.6%) and 3 (3.0%) respectively. Differences in outcome between groups were statistically significant (P=0.001). Above the empirical cut-off value of BNP (135 pg/mL) good prognosis was for 18 (24.3%) and bad prognosis was for 56 (75.7 %) patients and relative risk 3.48 in 95% CI (2.25-5.36). Conclusion: It can be concluded from this study that higher baseline plasma BNP concentration is associated with more adverse clinical outcomes in ACS patients. Since the baseline plasma BNP concentrations at the onset of event shows incremental prognostic value, so plasma BNP can be used clinically as a biomarker of prognosis in ACS patients.DOI: http://dx.doi.org/10.3329/cmoshmcj.v14i1.22870 Chatt Maa Shi Hosp Med Coll J; Vol.14 (1); Jan 2015; Page 1-5

Background: Majority of the patients of coronary heart disease (CHD) in our country are above 40 years of age but a good number of patients belong to the age under 40, the most valuable and productive period of life during which they can devote themselves to uplift their family, society and country and can participate in nation building activities.3,4 The number of young individuals falling into the spectrum of CHD is increasing everywhere However, this age trend is peculiar in relation to the western age incidence.5 Our objective was to investigate the lipid profile and coronary angiographic pattern in young Bangladeshi patients with acute coronary syndrome and also to find out the relationship between dyslipidemia and coronary artery disease in this age group. Methods: This observational study was carried out in National Institute of Cardiovascular Diseases (NICVD) during the period of January 2000 to December 2000. A brief history was recorded on the date of admission and fasting lipid profile was done within 24 hours of admission. Other associated major risk factors were looked for and recorded accordingly. After stabilization oh the acute condition patient was prepared for coronary angiogram and informed consent was taken. Accordingly elective CAG was done. Among them total 64 patients of ACS, underwent coronary angiogram in the cath lab of NICVD, were selected randomly of which of which 32 patients were up to the age 40 years (Group- I) and 32 were above 40 years of age (Group-II). Patient of ACS of either sex having no age limitation were included without prior history of Percutaneous Coronary Intervention or Coronary Artery Bypass Graft surgery. The findings were reviewed and scrutinized carefully by two interventional cardiologists. In doubtful cases third expert reviewed the CD. If a consensus was not reached due to technical or visual error, the case wais discarded from the study. Details of CAG findings i.e. site and number of diseased vessels, location, morphology and pattern of lesion were studied and recorded accordingly. Results: The prevalence of dyslipidaemia and positive family history were more in group I than group II. Younger age group has less favorable lipid profile than older age group having raised total cholesterol in 31.3 percent cases, low HDL in 12.5 percent cases and raised LDL in 31.3 percent cases, while in older age group, it was 21.8, 25.0, 0 and 18.7 percent, respectively. CAG study of the patients showed that no vessel involvement was more common in group I than group II (21.9% vs 12.5%), but triple vessel disease was more common in group II (12.5% vs 21.8%). Single vessel and double vessel diseases were similar in both the groups. Involvement of LAD was slightly more in-group I than group II (68.8% vs 65.6%) and involvement of LCX and RCA were less in group I than group II (21.9% vs 34.3%, and 43.8% vs 78.1%, respectively). Diffuse LAD and RCA lesions were more in group II (36.4% vs 52.4% and 42.9% vs 48.0%, respectively), but diffuse LCX lesion was more in group I (42.9 vs 36.4%). Multiple irregular lesions are more common in older age group (53.1%) than younger age group (28.1%). Conclusion: The younger age group has less favorable lipid profile than older age group having raised total cholesterol, decreased HDL and raised LDL. CAG findings show that most of the lesions are present in LAD (having less impressive LVEF) as like as in older age group, but older age group has more multiple irregular lesions. Prevalence of >2 lesions in one coronary artery was more in group I (31 vs. 25%) but difference was not statistically significant.

The purpose of study. To evaluate efficiency of different coagulants used under transcutaneous coronary interventions in patients with acute coronary syndrome without elevation of ST segment.The methods. The sampling of 346 patients was randomized in two groups. In the group I (n=155) transcutaneous coronary intervention was implemented using bivalirudin and in group II (n = 191) - using unfractionated heparin. The additional randomization of patients of group I: in subgroup A (n = 77) infusion of bivalirudin continued during four hours after intervention and in subgroup B (n = 78) infusion was discontinued in X-ray operating room. The criteria of inclusion: patients with acute coronary syndrome without elevation of ST segment with multi-vascular affection of coronary channel (risk on SYNTAX score = 23-32); high and medium degree of risk according GRACE scale; absence of re-vascularization of myocardium in anamnesis. The criteria of exclusion: patients with very high risk according GRACE scale; affection of left coronary artery trunk. The results. During period of hospitalization, total rate of intra- and post-operative cardiovascular complications had no reliable differences in two groups and amounted to 7.1% and 8.4% correspondingly (p = 0.6423). The serious bleedings (BARC 3 and 5) occurred reliably more frequently in patients of group II. Also, the groups had no differences in rate of development of acute thrombosis of stents. In subgroup A reliably less frequently occurred serious cardiovascular complications as compared with patients of subgroup B (1,3% и 13% correspondingly; р = 0,001). At that, rate of bleeding reliably had no differences. At trans-radial access, in patients of group I rate of bleeding and cardiovascular complications amounted to 0% and 2.9% and at trans-femoral access these indices were reliably higher - 3,3% и 10% correspondingly (р < 0,001). In group II a similar tendency is noted: at trans-radial access these indices amounted to 6% and 4.6% and at trans-femoral - 33.7% and 11.9% correspondingly (р

The aim of the study was to assess the association of metabolic syndrome in patients with acute coronary syndrome and the impact of metabolic syndrome on clinical outcome. Total 210 ACS patients were included in this study and divided in group I & II on the basis of presence or absence of MS respectively. Among the study patients mean age in group I and group II was 52.99 ± 11.49 years and 53.34 ± 12.54 years respectively. Among the risk factors, hypertension (70%vs 15%), dyslipidemia (100 vs. 97%), diabetes mellitus (36.4% vs. 6%) were significant between two groups. Mean waist circumference recorded was 103.12 ± 4.15 in group I and 96.50 ± 6.43 in group II which was significant. Present study showed, in hospital outcome was worse in group I in comparison to group II and was significant, like cardiogenic shock (11% vs. 1%), LVF (28.2% vs. 16%), and CVD (5.45 vs. 0%). But there were no significant difference in heart block, tachyarrhythmia, cardiac arrest, reinfarction and death. Complications were far more in group I than in group II (14.5% vs. 52.0%) which was also highly significant. So, we conclude that the presence of MS in patients suffered from ACS was associated with a greater incidence of in-hospital cardiovascular complications and mortality.DOI: http://dx.doi.org/10.3329/jom.v15i1.19857 J Medicine 2014; 15: 31-35

Background: C- reactive protein (CRP) is an acute phase inflammatory mediator that has been implicated as a risk factor for cardiovascular disease (CVD). The clinical presentation of acute coronary syndrome (ACS) ranges from unstable angina (UA) to non ST- segment elevation myocardial infarction (NSTEMI) and ST- segment elevation myocardial infarction (STEMI). Although, elevated levels of serum CRP have been reported in patients with CVD, the serum levels of CRP in patients with NSTEMI ACS is unknown. The purpose of the study was to determine whether the serum levels of CRP are higher in patients with NSTEMI ACS as compared to healthy controls. Methods: The study subjects consisted of two groups. Group I: (controls) twenty- five age-matched healthy men and Group II: Forty- five NSTEMI ACS patients. Fasting blood samples were collected and serum levels of CRP were measured by using highly sensitivity immunoassay rate method technology. Results: The serum levels of CRP in Group I and Group II were 3.2 ± 0.25 and 11.32 ± 2.1 mg/L, respectively and these values were significantly different from each other (p< 0.05). Group II showed a 253% higher level of CRP as compared to Group I subjects. Conclusion: The results demonstrate that the serum levels of CRP are higher in patients with NSTEMI ACS as compared to controls. Serum CRP levels are elevated in patients with NSTEMI ACS and may contribute to the inflammation and thrombosis associated with acute coronary syndrome.

Abstract BACKGROUND: Evidence regarding the relationship between unbound bilirubin levels and acute bilirubin encephalopathy was limited. Therefore, this study set out to investigate whether the unbound bilirubin level was independently related to acute bilirubin encephalopathy in children who underwent exchange transfusion after adjusting for other covariates. METHODS: A total of 46 neonates who underwent exchange transfusion were involved in The First People's Hospital Of Changde City in China from 2016-1-1 to 2018-12-31. The target independent variable and the dependent variable were unbound bilirubin levels measured at baseline and acute bilirubin encephalopathy respectively. Covariates involved in this study included sex, age, birth weight, blood glucose, red blood cell, hemolysis, receive phototherapy before exchange transfusion. RESULTS: The average gestational age of 46 selected participants was 38.6 ± 1.3 weeks old, the average age was 146.5 ± 86.9 hours old, 52.17% of them were male. Result of fully-adjusted binary logistic regression showed unbound bilirubin levels were positively associated with risk of acute bilirubin encephalopathy after adjusting confounders (Odds ratio = 1.41, 95% confidence intervals 1.05-1.91, P value <0.05). CONCLUSION: Unbound bilirubin levels are associated with neonatal acute bilirubin encephalopathy. The mechanism of unbound bilirubin levels leading to neonatal acute bilirubin encephalopathy needs to be further explored.

PURPOSE: To analyze the effects of sodium hyaluronate and carboxymethylcellulose membrane on collagen and fibroblast formation in bowel suture healing in rats. METHODS: 48 male Wistar rats, weighing 250 to 343g, were randomized into two groups: group I - bowel suture without applying a biologically absorbable membrane and group II - bowel suture with application of an absorbable membrane. The two groups were divided into subgroups of 3, 14 and 30 days of observation, with 8 rats in each subgroup. All were sacrificed after the end of the observation period. RESULTS: No morbidity or mortality was observed during the experiment. The amounts of collagen in group I were 23.4%, 72.1% and 67.6% and in group II were 22.5%, 52.5% and 51.6%, for the subgroups of 3, 14 and 30 days, respectively. Comparison between groups showed that the 14-day (p=0.0013) and 30-day (p=0.0587) subgroups had significant variance, with larger collagen zones in animals in which the membrane was not applied. However, with regard to fibroblasts, group I had 2%, 13% and 8% and group II had 2%, 10% and 8%, for the 3-day (p=1.0), 14-day (p=0.3184) and 30-day (p=0.5995) subgroups, respectively, showing no significant variance. CONCLUSION: The use of the biologically absorbable membrane cause a decrease in collagen formation, while not altering the number of fibroblasts, in bowel suture healing in rats, without increased morbidity and mortality.

Abstract Introduction The most common cause of mortality among chronic hemodialysis (HD) patients is cardiovascular disease. Hypervolemia is an important risk factor for hypertension and cardiovascular mortality in HD patients that include chronic volume overload and interdialytic weight gain (IDWG).IDWG affects cardiovascular morbidity and mortality Daily fluctuations in extracellular fluid volume might promote cardiac remodeling resulting in left ventricular hypertrophy (LVH) and cardiac fibrosis. Aim of the study to assess interdialytic weight gain and (its relation to morbidity and mortality) among patients on maintenance hemodialysis. Patient and methods 100 ESRD patients on regular hemodialysis included in study in Ain Shams University hospitals in march 2016 and followed up after one year in march 2017. Type of study cohort study Patients were divided into two groups according to interdialytic weight gain (IDWG): Group I (high IDWG) 50 patients with Absolute weight gain 4kg or more. Or relative IDWG more than 3.5% of total body weight. Group II (low IDWG) 50 patients with absolute weight gain less than 3kg Or relative IDWG less than 3.5% of total body weight. Echocardiography (TTE) for all patients at the start of the study and followed up after one year for detecting outcomes included all-cause mortality, cardiovascular mortality, hospitalization for heart failure/volume overload, hospitalization for myocardial infarction, stroke. Results we found that patient with high (IDWG) group II has significantly higher increase in left ventricular mass index (LVMI),inferior vena cava (IVC) diameter and significantly higher decrease in ejection fraction more than low IDWG group I. Conclusions Patients with high IDWG group II at higher risk of increase LVMI, decrease ejection fraction, increase in interventricular septum (IVS), increase in inferior vena cava diameter more than patients of low IDWG group I and has more cardiovascular morbidity and mortality.

Background: Cervical cancer is the most common cancer of Bangladeshi women diagnosed mostly (>80%) at stage II and stage III. Rdaiotherapy (both teletherapy and brachytherapy) is the most important modality of treatment at these stages.Objective: To compare the local control, diseases free survival and overall survival between the (cancer cervix) patients treated randomly by two schedules of radiotherapy. Method: From June 1996 to June 2005, patients with histologically confirmed carcinoma cervix (Ca.cervix) were treated by external beam therapy (EBRT) as well as intra cavitery brachytherapy (ICRT) along with concurrent/sequential chemotherapy with cisplatin and 5- Fluorouracil. EBRT was given by cobalt60 teletherapy machine and ICRT by caesium137 low dose rate machine. The patients were divided into two groups according to treatment schedules. Group I: the patients in this group received EBRT in whole pelvis in two steps, first with open field upto 10-20 Gy then by applying midline shield with lead block 30-40Gy in 25-28 total fractions, five days a week; they also received 50-70 Gy to point A by ICRT in 2-4 weekly fractions. Group II: patients in this group received with open field a dose of 45-50Gy in 25-28 fractions, 5 days a week by EBRT and 25-30 Gy at point A by ICRT in 1-2 weekly fractions.Result: In Group I, 96 out of 101 and in Group II, 104 out of 118 patients were eligible for evaluation. In both groups patients were distributed according to stages and age more or less equally; their age range were 30-70 years and mean age was 47.2 years in Group I and age range were 25-80 years and mean age was 46 years in Group II. Squamous cell carcinoma were found (90%) and performance status was WHO grade 0-1 (>75%) in both groups. Local control of disease at 5 years was 65% in group I and 51% in group II. Overall survival at 2 years, 5 years, 7 years and 9 years in group I, was 71%, 64%, 55%, 46% and in group II, 54%,50%, 43%,32% respectively. Distant metastasis occurred in 22% in-group I and 28% in-group II. Lymph node, lung, liver, peritoneum were common site of metastasis. Proctitis, cystitis, vaginal stenosis in group I was 80%, 33% 16% and in Group II 29%, 13% and 5% respectively. Conclusion: External beam therapy and brachytherapy was effective treatment in carcinoma. Cervix in both operable and inoperable stages. In small volume of tumor, both schedules of radiotherapy were more or less equivalent but in bulky diseases Group I schedule that was higher dose by brachytherapy at point A showed better result; though the complication was more DOI: http://dx.doi.org/10.3329/bjog.v25i2.13739 Bangladesh J Obstet Gynaecol, 2010; Vol. 25(2) : 50-58
