RESUMEN

BACKGROUND: Polyhydroxybutyrate is a biopolymer produced by bacteria and archaea under nitrogen-limiting conditions. PHB is an essential polymer in the bioplastic sector because of its biodegradability, eco-friendliness, and adaptability. The characterization of PHB is a multifaceted process for studying the structure and its properties. This entire aspect can assure the long-term viability and performance attributes of the PHB. The characteristics of PHB extracted from the halophile Brachybacterium paraconglomeratum were investigated with the objective of making films for application in healthcare. RESULTS: This was the first characterization study on PHB produced by a rare halophile, Brachybacterium paraconglomeratum (MTCC 13074). In this study, the strain produced 2.72 g/l of PHB for.5.1 g/l of biomass under optimal conditions. Methods are described for the determination of the physicochemical properties of PHB. The prominent functional groups CH3 and C = O were observed by FT-IR and the actual chemical structure of the PHB was deduced by NMR. GCMS detects the confirmation of four methyl ester derivatives of the extracted PHB in the sample. Mass spectrometry revealed the molecular weight of methyl 3-hydroxybutyric acid (3HB) present in the extract. The air-dried PHB films were exposed to TGA, DSC and a universal testing machine to determine the thermal profile and mechanical stability. Additionally, the essential property of biopolymers like viscosity was also assessed for the extracted PHB. CONCLUSIONS: The current study demonstrated the consistency and quality of B. paraconglomeratum PHB. Therefore, Brachybacterium sps are also a considerable source of PHB with desired characteristics for industrial production.

RESUMEN

BACKGROUND: Environmental enteric dysfunction (EED) is an enigmatic disorder of the small intestine that is postulated to play a role in childhood undernutrition, a pressing global health problem. Defining the incidence of this disorder, its pathophysiological features, and its contribution to impaired linear and ponderal growth has been hampered by the difficulty in directly sampling the small intestinal mucosa and microbial community (microbiota). METHODS: In this study, among 110 young children (mean age, 18 months) with linear growth stunting who were living in an urban slum in Dhaka, Bangladesh, and had not benefited from a nutritional intervention, we performed endoscopy in 80 children who had biopsy-confirmed EED and available plasma and duodenal samples. We quantified the levels of 4077 plasma proteins and 2619 proteins in duodenal biopsy samples obtained from these children. The levels of bacterial strains in microbiota recovered from duodenal aspirate from each child were determined with the use of culture-independent methods. In addition, we obtained 21 plasma samples and 27 fecal samples from age-matched healthy children living in the same area. Young germ-free mice that had been fed a Bangladeshi diet were colonized with bacterial strains cultured from the duodenal aspirates. RESULTS: Of the bacterial strains that were obtained from the children, the absolute levels of a shared group of 14 taxa (which are not typically classified as enteropathogens) were negatively correlated with linear growth (length-for-age z score, r = -0.49; P = 0.003) and positively correlated with duodenal proteins involved in immunoinflammatory responses. The representation of these 14 duodenal taxa in fecal microbiota was significantly different from that in samples obtained from healthy children (P<0.001 by permutational multivariate analysis of variance). Enteropathy of the small intestine developed in gnotobiotic mice that had been colonized with cultured duodenal strains obtained from children with EED. CONCLUSIONS: These results provide support for a causal relationship between growth stunting and components of the small intestinal microbiota and enteropathy and offer a rationale for developing therapies that target these microbial contributions to EED.

RESUMEN

There is growing interest in the role of Social Prescribing (SP) to help promote mental well-being and support individuals with mental health difficulties. Yet, implementation of SP to children and young people (CYP) has proved slow and underdeveloped compared with adult populations. Understanding the barriers and facilitators will help key stakeholders to better embed SP for CYP into practice. Using the Theoretical Domains Framework (TDF), a comprehensive, theoretical-led framework, underpinned by 33 behaviour change theories and 128 constructs, perceived barriers and facilitators to SP were investigated. The sample comprised of 11 Link Workers and 9 individuals involved in facilitating SP with CYP, who took part in semi-structured interviews. Transcripts were analysed using a deductive thematic analysis, and themes were coded under each theoretical domain. Overall, 33 barriers and facilitators for SP were identified across 12 domains of the TDF. Under capability, barriers and facilitators were found for knowledge, skills, memory/attention/decision making processes, and behavioural regulation. For opportunity, barriers and facilitators were found for social/professional influences, as well as environmental context and resources. Finally, for motivation, domains covered included: beliefs about consequences, beliefs about capabilities, optimism, motivations/goals, reinforcement, and emotions. Findings suggest that a wide range of barriers and facilitators affect the implementation of CYP SP to improve mental health and well-being. Interventions which target different domains related to capability, opportunity and motivation should be developed to better facilitate CYP SP.

RESUMEN

Liver problems are a worldwide concern, and conventional medicinal therapies are ineffective. Hence, safeguarding the healthy liver is vital for good health and well-being. Infections due to virus, immune problems, cancer, alcohol abuse, and an overdose of drugs are some of the causes of liver diseases. Antioxidants derived from medicinal plants and conventional dietary sources can protect the liver from damages caused by oxidative stress system and various chemicals. Plants and plant-derived phytochemicals are appealing hepatoprotective agents since they have less side effects and still there is a lot of interest shown in using herbal tonics for treating liver disorders. This review therefore primarily focuses on newly discovered medicinal plants and compounds produced from plants that fall under the classifications of flavonoids, alkaloids, terpenoids, polyphenolics, sterols, anthocyanins, and saponin glycosides, all of which have the potential to be hepatoprotective. Hosta plantaginea, Ligusticum chuanxiong, Daniella oliveri, Garcinia mangostana, Solanum melongena, Vaccinium myrtillus, Picrorhiza kurroa, and Citrus medica are some potential plants having hepatoprotective effects. We conclude that these phytochemicals and the plant extracts listed above are used in the future to treat a variety of liver diseases, additional research is still needed to develop safer and more potent phytochemical drugs.

RESUMEN

The present study investigates the effects of Supplementary diet Hygrophila auriculata on the growth, survival, biochemical and haematological parameters of Cirrhinus mrigala. The seaweed was administered to the fish possessing an initial average weight of 14.063 ± 1.828 g. Fish were fed with supplementary diet H. auriculata exhibited significant difference (P < 0.05) in the growth performance, haematological indices such as RBC count, haematocrit volume, haemoglobin, WBC, MCV, MCH and MCHC concentration in contrast to the control after a period of 8 weeks. Also, there were significant differences in biochemical parameters (P < 0.05), between the fish supplemented with dietary H. auriculata extract and the control group. These findings suggest that the administration of H. auriculata extract has a positive effect on the immunological indices and the immune system activity in Mrigal fish.

RESUMEN

AIM: There is insufficient knowledge on the * duodenal histology and Helicobacter pylori infection in malnourished Bangladeshi children. Therefore, we attempted to explore the prevalence of H. pylori infection and duodenal histopathology in 2-year-old chronic malnourished Bangladeshi slum-dwelling children and investigate their association with dyspeptic symptoms. METHODS: This cross-sectional study was conducted using the data of the Bangladesh Environmental Enteric Dysfunction study in an urban slum of Dhaka, Bangladesh. With a view to address the association of environmental enteric dysfunction (EED) with stunting, upper gastrointestinal endoscopy was performed on 54 chronic malnourished children {31 stunted [length-for-age Z-scores (LAZ) <-2] and 23 at risk of stunting (LAZ <-1 to -2)} aged between 12-24 months and the mucosal biopsies were subjected to histopathological examination after obtaining proper clinical history. Stool antigen for H. pylori (HpSA) was assessed to determine H. pylori status. RESULTS: In all, 83.3% (45/54) of the children had histopathological evidence of duodenitis. Chronic mild duodenitis was found to be the most prevalent form of duodenitis (53.7%) in the children. Only 8.9% (4/45) of the children with duodenitis had dyspepsia (p < 0.05). The 14.8% (8/54) of the children were found positive for H. pylori infection. Logistic regression analysis revealed children positive for HpSA had significant association with dyspepsia (OR 9.34; 95% CI 1.54-56.80). CONCLUSIONS: The number of chronic malnourished children suffering from duodenitis was found to be very high. Majority of these children was asymptomatic. Children positive for HpSA had significant association with dyspeptic symptoms.

RESUMEN

OBJECTIVE: To evaluate enzymatic total serum bile acid quantification as a monitoring strategy for women with intrahepatic cholestasis of pregnancy (ICP) treated with ursodeoxycholic acid (UDCA). DESIGN: Cohort. SETTING: One UK university hospital. POPULATION: 29 ICP cases treated with UDCA. METHODS: Serial samples were collected prospectively throughout gestation. Total serum bile acids were measured enzymatically and individual bile acids by high-performance liquid chromatography-tandem mass spectrometry. Data were log-transformed and analysed with random effects generalised least square regression. MAIN OUTCOME MEASURES: The relationship between enzymatic total bile acid measurements and individual bile acid concentrations after UDCA treatment. RESULTS: In untreated women, cholic acid was the principal bile acid (51%) and UDCA concentrations were <0.5%, whereas UDCA constituted 60% (IQR 43-69) of serum bile acids following treatment and cholic acid fell to <20%. Changes in the total bile acid measurement reflected similar alterations in the concentrations of the pathologically elevated bile acids, e.g. a two-fold increase in enzymatic total bile acids is accompanied by approximately a two-fold increase in cholic acid and chenodeoxycholic acid at most UDCA doses (P < 0.001). Most of the effects of UDCA on cholic acid occur in the first week of treatment (60% relative reduction, P = 0.025, 95% CI 0.2-0.9, from 10 micromol/l (4.7-17.6) to 3.5 micromol/l (1.4-7.5). CONCLUSION: Ursodeoxycholic acid becomes the main component of the bile acid measurement after treatment. Enzymatic total bile acid assays are good predictors of both cholic acid and chenodeoxycholic acid, the primary bile acids that are raised prior to treatment. TWEETABLE ABSTRACT: Ursodeoxycholic acid constitutes approximately 60% of the bile acid measurement and reduces pathological cholic acid in treated women.

RESUMEN

AIMS: To identify the barriers to and enablers of effective insulin self-titration in people with Type 2 diabetes. METHODS: A qualitative semi-structured interview approach was used. Questions were structured according to the Theoretical Domains Framework, which outlines 14 domains that can act as barriers to and enablers of changing behaviour. Interviews were audio-recorded and transcribed verbatim. The data were coded according to the 14 domains, belief statements were created within each domain, and a frequency count of the most reported barriers and enablers was then carried out. Analyses were conducted by two researchers, and discrepancies agreed with a third researcher. RESULTS: A total of 18 adults with Type 2 diabetes took part in an interview. The majority were of South-Asian ethnicity (n = 8) and were men (n = 12). Their mean age was 61 years old. The mean duration of diabetes was 16 years and time on insulin 9 years. Inter-rater reliability for each of the domains varied (29-100%). The most frequently reported domains were Social Influence and Beliefs about Consequences; the least frequently reported were Optimism and Reinforcement. Interviewees reported receiving support to self-titrate from a range of sources. Self-titrating was perceived to have a range of both positive and negative consequences, as was not titrating. CONCLUSIONS: The findings highlight that those interviewed experienced a range of barriers and enablers when attempting to self-titrate. Improved education and training when initiating insulin treatment among adults with Type 2 diabetes, and throughout their journey on insulin therapy could help identify and address these barriers in order to optimize self-titration.

RESUMEN

INTRODUCTION: Breast metastasis is rare in childhood malignancies. Soft tissue sarcomas, especially rhabdomyosarcomas (RMS), and hematologic neoplasms, such as lymphomas, are the most common tumors that metastasize to the breast, albeit rare. MATERIALS AND METHODS: All cases with breast metastasis within a cohort of 200 RMS patients followed in our institution during 1990 to 2014 were assessed retrospectively and the literature was reviewed. RESULTS: There were 3 adolescent female patients with breast metastasis. All had alveolar histology. The primary tumors were in the parameningeal sites, extremities, and the perineum, respectively. Two patients had breast metastasis at diagnosis, and 1 during follow-up. In 1 breast lesion, there was a complete response to chemotherapy, and in another there was no response to chemotherapy, and the patient underwent radical mastectomy. In the third patient, there was partial response, and lesions progressed. All patients died with recurrent/progressive disease, 2 with no recurrence in the breast. In the English literature, there are 70 cases including our cases. All but 1 involve female patients, all adolescents, most have alveolar histology and poor prognosis. All had chemotherapy, whereas some had surgery and/or radiotherapy for local treatment. CONCLUSION: Breast metastasis should be considered in adolescent female patients with RMS. Optimal management is not clear. Besides chemotherapy, mastectomy and radiotherapy should be considered on a case basis.

RESUMEN

Cervical cancer is the most common cancer in women in developing countries comprising 20-30% of female cancer. More than 70% of cervical cancer patients of Bangladesh attend in hospital in inoperable stages (IIB, III & IV). Only 30% cases can be treated by primary surgery. This prospective cross-sectional study was conducted by Gynaecologic Oncology Division of the Department of Obstetrics & Gynaecology of Bangabandhu Sheikh Mujib Medical University (BSMMU), Bangladesh from November 2011 to May 2012. The objectives of this study were to evaluate the number of pelvic lymph nodes removed, to determine the rate of pelvic lymph node involvement & also to evaluate the relationship between parametrial invasion and pelvic lymph node metastasis. During this period 105 cases underwent type III radical hysterectomy with bilateral pelvic lymph nodes dissection. Majority of the patients (60%) were in the age group of 31-50 years. Regarding histological type, most of the cases were invasive squamous cell carcinoma (85%), followed by adenocarcinoma (9%) and adenosquamous type (2%). According to grading of the tumours, grade I, II, III were 45%, 43%, 8% respectively and in 3% cases grading could not be identified.

RESUMEN

Despite the widespread use of hormone replacement therapy, various reports on its side effects have generated an increasing interest in the development of safe natural agents for the management of postmenopausal discomforts. The present randomized, double-blinded, placebo-controlled study investigated the effect of 90-day supplementation of a standardized extract of fenugreek (Trigonella foenum-graecum) (FenuSMART™), at a dose of 1000 mg/day, on plasma estrogens and postmenopausal discomforts. Eighty-eight women having moderate to severe postmenopausal discomforts and poor quality of life (as evidenced from the scores of Greene Climacteric Scale, short form SF-36® and structured medical interview) were randomized either to extract-treated (n = 44) or placebo (n = 44) groups. There was a significant (p < 0.01) increase in plasma estradiol (120%) and improvements on various postmenopausal discomforts and quality of life of the participants in the extract-treated group, as compared with the baseline and placebo. While 32% of the subjects in the extract group reported no hot flashes after supplementation, the others had a reduction to one to two times per day from the baseline stages of three to five times a day. Further analysis of haematological and biochemical parameters revealed the safety of the extract and its plausible role in the management of lipid profile among menopausal women.

RESUMEN

The bioremediation potential of Pseudomonas fluorescens was studied in an Inverse Fluidized Bed Biofilm Reactor under batch recirculation conditions using synthetic phenolic effluent of various concentrations (400, 600, 800, 1000 and 1200 mg/l). The performance of the reactor was investigated and the characteristics of biomass and biofilm were determined by evaluating biofilm dry density and thickness, bioparticle density, suspended and attached biomass concentration, chemical oxygen demand and phenol removal efficiency. Biodegradation kinetics had been studied for suspended biomass culture and biofilm systems with respect to its specific growth and substrate consumption rates. Suspended biomass followed substrate inhibition kinetics and the experimental data fitted well with the Haldane model. The degradation kinetic behavior of biofilm revealed that a well adapted biofilm system with effective control of biofilm thickness in an inverse fluidized bed biofilm reactor overcomes substrate inhibition effects by tolerating higher phenol concentration and fitted well to the Monod model.

RESUMEN

This case-control study was done to find out whether elevated serum CRP in early pregnancy is a predictor of GDM and conducted under joined supervision of Obstetrics & Gynecology Department, Bangabandhu Sheikh Mujib Medical University (BSMMU) Hospital and Biomedical Research Group (BMRG), BIRDEM, from August 2005 to November 2007. Pregnant mothers at their first 16 weeks of gestation without any medical disorder of pregnancy were included in the study. For the purpose of this study blood samples were again collected for OGTT at their 16weeks, 24-28 weeks and 32 weeks of pregnancy to detect GDM. After confirmation of GDM, C-reactive protein and C-peptide were done from the preserved fasting serum sample at the end of this study to compare GDM with control group. A total of 297 patients were included in this study. Among them 145(48%) patients completed follow up, 59(20%) lost from follow-up and 11(4%) patients had abortion; 82(28%) are due for follow up 31(10%) pregnant patients developed GDM subsequently. Finally 28 GDM patients were taken as cases and 71 were control matched for their gestational age and parity. At earlier weeks of gestation, hsCRP could predict (PPV) development of GDM in 59% with NPV 84%, sensitivity 61% and specificity 83%. C-peptide in the 50th percentile could predict (PPV) development of GDM in 58% with NPV 96%, sensitivity 72% and specificity 93%. The present data indicates that hsCRP and C-peptide both is sensitive markers in predicting GDM.

RESUMEN

A 25 years married women having one child delivered vaginaly presented in the department of Obs & Gynae, Bangabandhu Sheikh Mujib Medical University, Bangladesh on April 2013 with pelvic pain and discomfort. No history of previous pelvic trauma was present. Patient examination showed a isolated mass in the right lower abdomen, right adnexa, extending to the pelvic wall upto lower end of ureter. Tumor markers were within normal limit. Intravenous pyelogram (IVP) showed mild right hydroureter and hydronephrosis with obstruction at the lower end of ureter. She was diagnosed as a case of adnexal mass with mild hydroureter & mild hydronephrosis and it was decided to operate on the patient. The surgical approach was transabdominal. On laparotomy a pseudocystic lesion 12×10cm in size was found over the right paracolic gutter and extending down into the pelvis involving the right parametrium. No abnormality was found in the uterus or tubes. The histological examination revealed a desmoid tumor of the pelvis. The patient's recovery was uneventful.

RESUMEN

The study was performed to determine the antibacterial effect of aqueous extract of garlic (Allium sativum) against standard strain of Escherichia coli ATCC 25922. An interventional study was conducted in Department of Pharmacology and Therapeutics in collaboration with Department of Microbiology, Mymensingh Medical College, Mymensingh. Antibacterial effect of AGE was determined by disc diffusion method. Sensitivity of AGE determined in disc diffusion and the zone of inhibition (ZOI) was 4 mm, 10 mm and 20 mm at 25 µg/10 µl, 50 µg/10 µl and 100 µg/10 µl concentrations respectively. From the findings it is clearly determined the extract has definite antibacterial effect upon Escherichia coli. Further studies are required to detect and isolate the active ingredients present in the Garlic extract as well as detail steps of mechanism responsible for antibacterial effect. Then their effects against the studied organism should be studied in vivo separately and its toxicity profile should also be taken into account.

RESUMEN

Disease susceptibility and genetic variability in 10 eggplant genotypes were studied after inoculating Phomopsis vexans under confined field conditions. Random amplified polymorphic DNA (RAPD) markers were used to assess genetic variation and relationships among eggplant genotypes. The disease index of leaves ranged 0.208-13.79%, while fruit infection ranged 2.15-42.76%. Two varieties, Dohazari G and Laffa S, were found to be susceptible, 6 were moderately resistant, 1 was moderately susceptible, and BAU Begun-1 was resistant to P. vexans. Amplification of genomic DNA by using 3 RAPD primers produced 20 bands: 14 (70%) were polymorphic and 6 (30%) were monomorphic. The highest intra-variety similarity indices values were found in ISD 006, Ishurdi L, Jessore L, and BAU Begun-1 (100%), while the lowest was in Dohazari G (90%). The lowest genetic distance (0.0513) and the highest genetic identity (0.9500) were observed between the ISD 006 and Ishurdi L combinations. A comparatively higher genetic distance (0.3724) and the lowest genetic identity (0.6891) were observed between the ISD 006 and Dohazari G combinations. A dendogram was constructed based on Nei's genetic distance, which produced 2 main clusters of the genotypes - Cluster I: ISD 006, Ishurdi L, Marich begun L, BAU Begun-1, Marich begun S, and Chega and Cluster 2: Laffa S, Dohazari G, Jessore L, and Singhnath. Genetic variation and its relationship with disease susceptibility were assessed using RAPD markers, to develop disease-resistant varieties and improve eggplant crops.

RESUMEN

This study assessed maternal serum copper and zinc levels in preeclampsia to find out the role of trace element disorder in the aetiology of preeclampsia. This cross sectional study was conducted in the dept of Physiology of BSMMU during 2009. Sixty patients of Preeclampsia (BP--140/90 aged 18-39 years, with >20th weeks of pregnancy with proteinuria and edema) participated. Thirty normotensive gravida was control. All subjects were collected from in and out patient department of Obstetric and Gynecology of BSMMU and Dhaka medical college hospital. Serum copper and zinc levels were measured by auto analyzer and atomic absorption sprectrophotometric method respectively. Data were compared between preeclampsia and normotensive pregnant women. Data were expressed as mean and SD and independent sample 't' test and two proportion 'z' test was used for statistical analysis. Mean value of maternal serum zinc (p<0.001) and copper (<0.01) levels were significantly decreased in preeclampsia. In addition Cu/Zn ratio was significantly higher (<0.01) in preeclampsia. Hypozincemia was found in 13% and hypocupremia was found in 38% of preeclampsia. The result of this study concludes that trace element disorders may be involved in the etiology of preeclampsia.

RESUMEN

This study was done to describe the clinical spectrum, EEG characteristics and treatment modalities in children with continuous spike and slow wave in sleep (CSWS). Ten patients with CSWS had been treated between 2012 and 2013. Mean age of the patients was 6.9 years; male female ratio was 3:2. The main etiologic group in this study was epilepsy (10), cerebral palsy (3) and brain lesion (arachnoid cyst). All the patients had prior seizure. Presenting features were abnormal behavior (4), agitation (4), aggression (4), eye blinking (2) and involuntary movement (2). Three patients had speech regression and 1 had motor regression. Regarding EEG finding, 7 out 10 cases had SWI>85% whereas, rest of them had SWI 50 to 80%. Most of the patients were resistant to two or more oral AED. The AED found to be efficacious were Midazolam drip, pulse methyl prednisolone and valproate. Eighty percent (80%) patient responded to midazolam drip. Methyl prednisolone caused 50% improvement in one patient but failed in 2 cases. In contrast to the previous studies where high dose valproic acid, levetiracetam, Injection ACTH was more efficacious, this study demonstrates significant positive result with midazolam drip.

RESUMEN

Hypothyroidism is one of the most common endocrine disorders encountered in clinical practice. Thyroid disorder is very common among the female. The aim of this study was to evaluate the effects of hypothyroidism on menstrual pattern and sub-fertility. This cross-sectional comparative study was carried out in the Department of Obstetrics and Gynecology with collaboration of endocrine department of Bangabandhu Sheikh Mujib Medical University (BSMMU) from July 2006 to June 2008, cases were collected from the thyroid clinic of this hospital. Total study subject were 139, among them hypothyroid cases were 79 and euthyroid were 60. Among the hypothyroidism group 62.0% (n=49) had normal menstrual cycle, 21.5% (n=16) had oligomenorrhoea, 10.1% (n=8) had polymenorrhoea and 6.3% (n=6) had amenorrhoea. On the contrary in euthyroid group 86.7% (n=52) had normal menstrual cycle, 6.7% (n=4) had oligomenorrhoea, 5.0% (n=3) had polymenorrhoea and 1.7% (n=1) had amenorrhoea. Proportion of abnormal menstrual history was found to high among hypothyroid group almost 34% (n=27) compared to euthyroid group 13.4% (n=8) and the difference was statistically significant (p<0.001). The proportion of primary subfertility in hypothyroid 11.4% (n=9) whereas in euthyroid cases 1.7% (n=1) and secondary subfertility in hypothyroid 7.6% (n=6) where as in euthyroid cases 5.0% (n=3). So, sub-fertility was higher among hypothyroid group compared to euthyroid group but the difference was not statistically significant (p>0.05). Overall sub-fertility was 13.7% (n=10) and it was 6.7% (n=4) among the euthyroid group. Among total hypothyroid group 60.7% (n=48) are the overt hypothyroid and 39.20% (n=31) are the sub-clinical hypothyroid group. The effect of hypothyroidism is significant on menstrual pattern and on fertility. Hypothyroid women had more menstrual disorders and also suffering from sub-fertility.
