RESUMO

Prevention of postpartum haemorrhage has been a major issue for its life threatening impact on maternal morbidity and mortality worldwide. Conventional continuous infusion of oxytocin has been employed for this condition. Apparently, in place of conventional oxytocics, application of carbetocin with longer half-life shows the same clinical benefits. This requires doing this present study. To compare the effectiveness of I/V bolus cabetocin and oxytocin infusion used for prevention of primary PPH after caesarean section. This descriptive cross-sectional comparative study was carried out in Department of Obstetrics and Gynaecology, Mymensingh Medical College Hospital (MMCH), Mymensingh, Bangladesh from November 2015 to April 2016. A total of 100 pregnant women undergoing elective or emergency caesarean section were enrolled and divided into two groups on the basis of exclusion and inclusion criteria. Group I (n=50) received bolus of 100µgm IV carbetocin after delivery of the baby & Group II (n=50) received 20 IU of oxytocin in 1000ml of Hartman solution I/V in 8 hours continuous infusion after delivery of the baby. Baseline demographic and obstetric profile, indications for C/S, estimated blood loss, hemoglobin level, additional uterotonic agents, blood pressure and the diuresis were compared immediate postoperatively and 24 hours after operation. The patients were followed up for 24 hours after operation regarding outcomes variables. Baseline profiles were similar between two groups. Regarding haemodynamic effects, both drugs have a hypotensive effect but a greater reduction in blood pressure is found in oxytocin group. There was no significant difference in respect of estimated blood loss, blood transfusion, additional oxytocics and diuresis between two groups. It can be concluded that a single injection of carbetocin is as effective as continuous oxytocin infusion to prevent postpartum haemorrhage, with similar haemodynamic profile. So, carbetocin as a uterotonic agent is an acceptable alternative for prevention of postpartum haemorhage after caesarean section.

RESUMO

Articular cartilage heals poorly but experiences mechanically induced damage across a broad range of loading rates and matrix integrity. Because loading rates and matrix integrity affect cartilage mechanical responses due to poroviscoelastic relaxation mechanisms, their effects on cartilage failure are important for assessing and preventing failure. This paper investigated rate- and integrity-dependent crack nucleation in cartilage from pre- to post-relaxation timescales. Rate-dependent crack nucleation and relaxation responses were obtained as a function of matrix integrity through microindentation. Total work for crack nucleation increased with decreased matrix integrity, and with decreased loading rates. Critical energy release rate of intact cartilage was estimated as 2.39 ± 1.39 to 2.48 ± 1.26 kJ m-2 in a pre-relaxation timescale. These findings showed that crack nucleation is delayed when cartilage can accommodate localized loading through poroviscoelastic relaxation mechanisms before fracture at a given loading rate and integrity state.

RESUMO

Intentional artificial rupture of the amniotic membranes during labour, called amniotomy or 'breaking of the water's, is one of the most commonly performed procedures in modern obstetric and midwifery practice. The primary aim of amniotomy is to speed up uterine contractions and therefore shorten the length of labour. However there are concerns regarding unintended adverse effects on the woman and baby. A prospective observational study was conducted to determine the effectiveness and safety of routine procedure of amniotomy to shorten the duration of labour (prolonged or not) in Mymensingh Medical College & Hospital, Mymensingh, Bangladesh from July 2011 to December 2011. One hundred low-risk women with spontaneous onset of labour at term with singleton fetus in cephalic presentation and intact amniotic membranes and a cervical dilatation between 4 and 5cm were conventionally assigned to have amniotomy during the course of labour. Maternal demographics, duration of labour (prolonged or not), maternal and perinatal outcome were considered as major outcome. Majority (49.0%) of the patients belonged to 21-25 years age group and primigravida was predominant and most of them had middle socio-economic conditions. More the three-fourth (89.0%) of the patients had head engaged. Rh-positive and negative were found 96.0% and 4.0% respectively. The primigravidae required 10.07±2.17 hours in 1st stage of labour and had 1.51±0.5 hours duration of 2nd stage of labour. In case of multi-gravidae it was 6.07±2.06 hours in 1st stage of and 1±0.5 hours in 2nd stage of labour. There was a marked reduction of amniotomy-delivery interval time in this study, which was 3 hours 40 minutes and whereas mean cervical dilatation was 4cm during amniotomy. Almost three fourth (72.0%) cases delivered vaginally among which, with episiotomy in 49.0% and without episiotomy in 23.0%. Instrumental delivery was in 9.0% of which 4.0% by forceps, 5.0% by vaccum extraction and 14.0% underwent LUCS. Still birth was found 2.0%, asphyxiated 3.0% and prenatal death 1.0%. In terms of referral to neonatal care unit it was found that 7.0% were asphyxiated. Asphyxia and low APGAR score was 4.0%, low birth weight 9.0%, instrumental delivery was 5.0%, Rh incompatibility was 2.0%. Only 1.0% babies needed admission to neonatal care unit and were intubated. So, Amniotomy significantly reduced the duration of the first stage of labour without affecting the oxytocin requirement, the rate of caesarean section and newborn outcome.

RESUMO

Patients with Diabetes Mellitus are at high risk of cardiovascular events because of abnormal lipid metabolism. Dyslipidemia is common in patients with Diabetes Mellitus (DM). However; in Bangladesh this issue is not yet properly addressed. The aim of this study is to determine the prevalence and patterns of dyslipidaemia in patients with DM in a divisional city Mymensingh. This cross-sectional study was conducted in randomly selected eligible patients from the indoor registry of the Department of Cardiology, Mymensingh Medical College Hospital (MMCH), Bangladesh from April 2012 to March 2013. A well structured questionnaire and blood investigation for lipid profile and blood sugar were the tools of data collection from 120 randomly selected DM patients registered in the department of cardiology, MMCH. Out of 120 enrolled participants the prevalence of dyslipidemia in DM patients was 86.0%, prevalence of dyslipidemia in males was 88.0% while in females was 85.0% but the difference was not significant (p=0.42). Regarding age group, BMI and duration of DM, there is no significant association exists with dyslipidemia. About half of the studied DM patients have high serum total cholesterol level (50.83%), while 22.5% had low serum HDL-C levels and 35.0% had high serum LDC-C level, most of patients had serum triglyceride levels above normal range (67.5%) and so the common patterns of dyslipidemia in this study were serum triglyceride level followed by total cholesterol. High prevalence of dyslipidemia among diabetes mellitus in Mymensingh city were observed and so the common patterns of dyslipidemia is triglyceride followed by total cholesterol. This study emphasizes the importance of screening of lipid profile as these abnormalities may lead to development of cardiovascular diseases.

RESUMO

Acute myocardial infarction (AMI) patients constitute a large proportion of admissions in coronary care unit and their management and risk stratification is of immense importance. A decrease in serum albumin concentration might be associated with an increased risk in the incident of both cardiovascular diseases and worse hospital outcome. We assessed whether serum albumin levels at admission was associated with in-hospital adverse outcome in patients with first attack of acute myocardial infarction (AMI). The aim of the study was to evaluate association of serum albumin level with in-hospital outcome in patients with first attack of acute myocardial infarction. This cross-sectional analytical study was conducted in the department of cardiology in Mymensingh Medical College Hospital, Mymensingh, Bangladesh from March 2017 to February 2018. Total 374 patients of first attack of acute myocardial infarction included considering inclusion and exclusion criteria. The sample population was divided into two groups: Group I (Patients with acute myocardial infarction with serum albumin <3.5gm/dl) and. Group II (Patients with acute myocardial infarction with serum albumin ≥3.5gm/dl). Serum albumin level was measured within 24 hours of admission and the incidence of in-hospital major cardiac outcomes was observed. In this study mean±SD serum albumin level of Group I, Group II were 3.02±0.12gm/dl, 4.48±0.50gm/dl respectively. In Group I patient, 52(59.80%), 7(8.00%), 10(11.50%), developed heart failure, cardiogenic shock, arrhythmias respectively and 8(9.20%) died and in Group II patient 20(7.90%), 7(2.80%), 8(3.20%) developed heart failure, cardiogenic shock, arrhythmias respectively and 4(1.60%) died out of them and all of these outcome were statistically significant. Mean±SD duration of hospital stay of the study population according serum albumin level, in Group I, 5.76±1.83 days, in Group II, 4.40±1.22 days which was statistically significant (p<0.05). In conclusion, patient with first attack of acute myocardial infarction serum albumin level below 3.50gm/dl increased the risk of worse in-hospital outcome.

RESUMO

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

RESUMO

Cervical cancer is one of cause of death in women in many developing countries. Persistent infection with Human Papilloma Virus (HPV), primarily high risk types 16 and 18, is recognized as a causal and essential factor for the development of cervical cancer. The objective of this cross sectional observational study is to detect the distribution of HPV-16 and HPV-18 among Onco E6 positive cases. Following universal safety precautions a total of 180 endocervical swabs were collected from Colposcopy clinic of Obstetrics and Gynaecology Department of Mymensingh Medical College Hospital (MMCH), Mymensingh, Bangladesh from January 2016 to December 2016. Laboratory work was done in the department of Microbiology, Mymensingh Medical College. E6 strip test is an immunochromatographic test based on the detection of HPV-E6 oncoprotein in cervical swab samples. Onco E6 cervical test was done on 180cases. Among them 60% were VIA positive and 120% were VIA negative. From this VIA positive cases 12(16.25%) were On E6 cervical test positive and from VIA negative cases 3(2.5%) were positive by this On E6 cervical test. From this 12 Onco E6 cervical test positive cases 10(%) were HPV-16 and 2(%) were HPV-18 and from VIA negative cases 3 were only HPV-16 by this test. Histopathological test done on 35 suspected cases and out of 08 cervical carcinoma cases 07 were positive by this Onco E6 cervical test which was also HPV-16 type. It may be concluded that HPV-16 is most prevalent type to cause cervical cancer and by this newly developed protein detection assay will be helpful to reduce over treatment and save many lives.

RESUMO

New results are reported from the operation of the PICO-60 dark matter detector, a bubble chamber filled with 52 kg of C_{3}F_{8} located in the SNOLAB underground laboratory. As in previous PICO bubble chambers, PICO-60 C_{3}F_{8} exhibits excellent electron recoil and alpha decay rejection, and the observed multiple-scattering neutron rate indicates a single-scatter neutron background of less than one event per month. A blind analysis of an efficiency-corrected 1167-kg day exposure at a 3.3-keV thermodynamic threshold reveals no single-scattering nuclear recoil candidates, consistent with the predicted background. These results set the most stringent direct-detection constraint to date on the weakly interacting massive particle (WIMP)-proton spin-dependent cross section at 3.4×10^{-41} cm^{2} for a 30-GeV c^{-2} WIMP, more than 1 order of magnitude improvement from previous PICO results.

RESUMO

Using the Penning trap mass spectrometer TITAN, we performed the first direct mass measurements of (20,21)Mg, isotopes that are the most proton-rich members of the A = 20 and A = 21 isospin multiplets. These measurements were possible through the use of a unique ion-guide laser ion source, a development that suppressed isobaric contamination by 6 orders of magnitude. Compared to the latest atomic mass evaluation, we find that the mass of (21)Mg is in good agreement but that the mass of (20)Mg deviates by 3 σ. These measurements reduce the uncertainties in the masses of (20,21)Mg by 15 and 22 times, respectively, resulting in a significant departure from the expected behavior of the isobaric multiplet mass equation in both the A = 20 and A = 21 multiplets. This presents a challenge to shell model calculations using either the isospin nonconserving universal sd USDA and USDB Hamiltonians or isospin nonconserving interactions based on chiral two- and three-nucleon forces.

RESUMO

In this Letter, we introduce the concept of in-trap nuclear decay spectroscopy of highly charged radioactive ions and describe its successful application as a novel spectroscopic tool. This is demonstrated by a measurement of the decay properties of radioactive mass A=124 ions (here, ^{124}In and ^{124}Cs) in the electron-beam ion trap of the TITAN facility at TRIUMF. By subjecting the trapped ions to an intense electron beam, the ions are charge bred to high charge states (i.e., equivalent to the removal of N-shell electrons), and an increase of storage times to the level of minutes without significant ion losses is achieved. The present technique opens the venue for precision spectroscopy of low branching ratios and is being developed in the context of measuring electron-capture branching ratios needed for determining the nuclear ground-state properties of the intermediate odd-odd nuclei in double-beta (ßß) decay.

RESUMO

We present precision Penning trap mass measurements of neutron-rich calcium and potassium isotopes in the vicinity of neutron number N=32. Using the TITAN system, the mass of 51K was measured for the first time, and the precision of the (51,52)Ca mass values were improved significantly. The new mass values show a dramatic increase of the binding energy compared to those reported in the atomic mass evaluation. In particular, 52Ca is more bound by 1.74 MeV, and the behavior with neutron number deviates substantially from the tabulated values. An increased binding was predicted recently based on calculations that include three-nucleon (3N) forces. We present a comparison to improved calculations, which agree remarkably with the evolution of masses with neutron number, making neutron-rich calcium isotopes an exciting region to probe 3N forces.

RESUMO

TRIUMF's Ion Trap for Atomic and Nuclear science (TITAN) constitutes the only high precision mass measurement setup coupled to a rare isotope facility capable of increasing the charge state of short-lived nuclides prior to the actual mass determination in a Penning trap. Recent developments around TITAN's charge breeder, the electron beam ion trap, form the basis for several successful experiments on radioactive isotopes with half-lives as low as 65 ms and in charge states as high as 22+.

RESUMO

Penning trap mass measurements of short-lived nuclides have been performed for the first time with highly charged ions, using the TITAN facility at TRIUMF. Compared to singly charged ions, this provides an improvement in experimental precision that scales with the charge state q. Neutron-deficient Rb isotopes have been charge bred in an electron beam ion trap to q=8-12+ prior to injection into the Penning trap. In combination with the Ramsey excitation scheme, this unique setup creating low energy, highly charged ions at a radioactive beam facility opens the door to unrivaled precision with gains of 1-2 orders of magnitude. The method is particularly suited for short-lived nuclides such as the superallowed ß emitter 74Rb (T(1/2)=65 ms). The determination of its atomic mass and an improved Q(EC) value are presented.

RESUMO

A 40 years old male patient of poor socioeconomic condition presented with a well circumscribed rough surfaced and fissured, verrucous plaque on left axilla and a similar lesion on right foot- which were clinically diagnosed as tuberculosis verrucosa cutis. He also had necrotic papular eruption with varioliform scarring in some lesions on upper back clinically diagnosed as papulonecrotic tuberculid. He had fever and cough and mild weight loss suspicious of pulmonary tuberculosis. On investigation ESR was raised, mild anaemia was present, MT was strongly positive, chest x-ray was suggestive of tuberculosis. So, he was diagnosed as a case of simultaneous occurrence of tuberculosis verrucosa cutis (TVC) with papulonecrotic tuberculid (PNT) with pulmonary tuberculosis (PTB). Standard anti tuberculosis chemotherapy already started to offer cure of all lesions.

RESUMO

Schizophrenia is a common, genetically heterogeneous disorder with a lifetime prevalence of approximately 1% in the general population. Linkage studies of affected families have now strongly implicated a susceptibility locus on chromosome 8p21-22. Tests of allelic association with markers on 8p21-22 should be able to localise any quantitative trait nucleotides (QTN's) or susceptibility mutations to within a few hundred kilobases. Three brain expressed candidate susceptibility genes, prepronociceptin (PNOC), neuronal cholinergic receptor, nicotinic, alpha polypeptide 2 (CHRNA2) and arylamine N-acetyltransferase 1 (NAT1) have been mapped to chromosome 8p21-22. A case-control, allelic association study was performed using a novel highly polymorphic dinucleotide repeat, D8S2611 near the PNOC gene, two previously characterised dinucleotide repeats, D8S131 and D8S131P at the CHRNA2 locus and an RFLP at the 3'UTR of the arylamine N-acetyltransferase 1 (NAT1) gene. No differences were found in allele frequencies between the patient and control groups. DNA variations or mutations at or near the three genes under study are unlikely to increase susceptibility to schizophrenia in our population sample.

RESUMO

Imaging studies have greatly improved the understanding of the pathology and physiology of psychiatric disorders, such as schizophrenia, affective disorders, obsessive-compulsive disorder, and Tourette syndrome. In the past few years, several neuroimaging studies have concentrated on patients with eating disorders. Although the number of studies is small compared with studies of other psychiatric disorders, the results are beginning to highlight potential areas in the brain that may lead to a better understanding of these disorders. Much research still is needed, and replication of results across centers is needed. The brain is an extremely complex organ; that eating disorders are a result of abnormalities in one specific area of the brain is unlikely. More likely is that several components of the brain have a role, including cortex and subcortical regions and involvement of several neurochemical pathways and circuits within the brain. Further studies are needed in this exciting development of research about eating disorders.

RESUMO

BACKGROUND: The guidelines for performing a one and a half ventricle repair with pulsatile bidirectional Glenn remains controversial. This retrospective report summarizes the experience of a single institution, with an attempt at providing an answer. METHODS: Fifty consecutive patients, aged 4 months to 42 years, underwent intracardiac repair along with a superior cavopulmonary connection. Twenty-seven of the patients had had previous surgical palliation. Repair consisted of patch closure of the ventricular septal defect (n = 25), tricuspid valve repair (n = 26), reconstruction of the right ventricular outflow tract (n = 34), transpulmonary annular patch (n = 34), right ventricle to pulmonary artery homograft conduit (n = 4), and concomitant repair of atrioventricular canal (n = 9). Ten patients were left with a fenestration in the atrial septum. RESULTS: There were six hospital deaths (12%) and two late deaths (4.5%). Forty-two survivors were followed from 8 months to 116 months. Eighty-eight percent are in functional class I. Actuarial survival at 97 months was 74%. CONCLUSIONS: Moderate right heart hypoplasia constitutes a safe anatomic category for a pulsatile bidirectional Glenn. It is advisable not to proceed with a one and a half ventricle repair if postoperative residual pulmonary artery hypertension is anticipated. Patients requiring an intricate intracardiac repair and those with concomitant right heart hypoplasia may be better suited for a Fontan type of repair to reduce the complexity of the procedure.

RESUMO

BACKGROUND/AIMS: We determined the role of gastrin in the regulation of cholangiocarcinoma growth. METHODS: We evaluated for the functional presence of cholecystokinin (CCK)-B/gastrin receptors in the cholangiocarcinoma cell lines, Mz-ChA-1, HuH-28 and TFK-1. We determined the effect of gastrin on the growth of Mz-ChA-1, HuH-28 and TFK-1 cells. We evaluated the effect of gastrin on growth and apoptosis of Mz-ChA-1 in the absence or presence of inhibitors for CCK-A (L-364, 718) and CCK-B/gastrin (L-365, 260) receptors, the intracellular Ca2+ chelator (BAPTA/AM), and the protein kinase C (PKC)-alpha inhibitor, H7. We evaluated if gastrin effects on Mz-ChA-1 growth and apoptosis are associated with membrane translocation of PKC-alpha. RESULTS: Gastrin inhibited DNA synthesis of Mz-ChA-1, HuH-28 and TFK-1 cells in a dose- and time-dependent fashion. The antiproliferative effect of gastrin on Mz-ChA-1 cells was inhibited by L-365, 260, H7 and BAPTA/AM but not L-364, 718. Gastrin induced membrane translocation of PKC-alpha. The inhibition of growth of Mz-ChA-1 cells by gastrin was associated with increased apoptosis through a PKC-dependent mechanism. CONCLUSIONS: Gastrin inhibits the growth of Mz-ChA-1, HuH-28 and TFK-1 cells. Gastrin inhibits growth and induces apoptosis in Mz-ChA-1 cells through the Ca2+-dependent PKC-alpha.

RESUMO

We report a rare variation in the pattern of totally anomalous pulmonary venous connection in that two vertical veins drained into the left brachiocephalic vein from a common pulmonary venous confluence. The child had associated right isomerism and functionally univentricular heart. Awareness of this possibility may avoid a reoperation or even death.
