Gender and urban-rural influences on antibiotic purchasing and prescription use in retail drug shops: a one health study.

INTRODUCTION: Few studies have reported antibiotic purchases from retail drug shops in relation to gender in low and middle-income countries (LMICs). Using a One Health approach, we aimed to examine gender dimensions of antibiotic purchases for humans and animals and use of prescriptions in retail drug shops in Bangladesh. METHODS: We conducted customer observations in 20 drug shops in one rural and one urban area. Customer gender, antibiotic purchases, and prescription use were recorded during a four-hour observation (2 sessions of 2 hours) in each shop. We included drug shops selling human medicine (n = 15); animal medicine (n = 3), and shops selling both human and animal medicine (n = 2). RESULTS: Of 582 observations, 31.6% of drug shop customers were women. Women comprised almost half of customers (47.1%) in urban drug shops but only 17.2% of customers in rural drug shops (p < 0.001). Antibiotic purchases were more common in urban than rural shops (21.6% versus 12.2% of all transactions, p = 0.003). Only a quarter (26.0%) of customers who purchased antibiotics used a prescription. Prescription use for antibiotics was more likely among women than men (odds ratio (OR) = 4.04, 95% CI 1.55, 10.55) and more likely among urban compared to rural customers (OR = 4.31 95% CI 1.34, 13.84). After adjusting for urban-rural locality, women remained more likely to use a prescription than men (adjusted OR = 3.38, 95% CI 1.26, 9.09) but this was in part due to antibiotics bought by men for animals without prescription. Customers in drug shops selling animal medicine had the lowest use of prescriptions for antibiotics (4.8% of antibiotic purchases). CONCLUSION: This study found that nearly three-quarters of all antibiotics sold were without prescription, including antibiotics on the list of critically important antimicrobials for human medicine. Men attending drug shops were more likely to purchase antibiotics without a prescription compared to women, while women customers were underrepresented in rural drug shops. Antibiotic stewardship initiatives in the community need to consider gender and urban-rural dimensions of drug shop uptake and prescription use for antibiotics in both human and animal medicine. Such initiatives could strengthen National Action Plans.

Malignant Infantile Osteopetrosis with Bone Marrow Involvement.

Osteopetrosis (Marble bone disease) is a very rare congenital genetic disease of skeleton, resulting from defective bone resorption, due to functionally defective osteoclast, leading to accumulation of excessive bone mass. Malignant infantile osteopetrosis (MIO) is one of the varieties of osteopetrosis, which is fatal and is diagnosed in early infancy. Malignant infantile osteopetrosis is present with abnormal bone remodeling, hematological abnormities, features of extramedullary hematopoiesis. Radiology is the key of diagnosis. In this case, we present a 5-monthold male infant diagnosed as malignant infantile osteopetrosis, who presented with bronchopneumonia, anemia, thrombocytopenia, hepatosplenomegaly, failure to thrive (FTT).

Motivating antibiotic stewardship in Bangladesh: identifying audiences and target behaviours using the behaviour change wheel.

BACKGROUND: South Asia is a hotspot for antimicrobial resistance due largely to over-the-counter antibiotic sales for humans and animals and from a lack of policy compliance among healthcare providers. Additionally, there is high population density and high infectious disease burden. This paper describes the development of social and behavioural change communication (SBCC) to increase the appropriate use of antibiotics. METHODS: We used formative research to explore contextual drivers of antibiotic sales, purchase, consumption/use and promotion among four groups: 1) households, 2) drug shop staff, 3) registered physicians and 4) pharmaceutical companies/medical sales representatives. We used formative research findings and an intervention design workshop with stakeholders to select target behaviours, prioritise audiences and develop SBCC messages, in consultation with a creative agency, and through pilots and feedback. The behaviour change wheel was used to summarise findings. RESULTS: Workshop participants identified behaviours considered amenable to change for all four groups. Household members and drug shop staff were prioritised as target audiences, both of which could be reached at drug shops. Among household members, there were two behaviours to change: suboptimal health seeking and ceasing antibiotic courses early. Thus, SBCC target behaviours included: seek registered physician consultations; ask whether the medicine provided is an antibiotic; ask for instructions on use and timing. Among drug shop staff, important antibiotic dispensing practices needed to change. SBCC target behaviours included: asking customers for prescriptions, referring them to registered physicians and increasing customer awareness by instructing that they were receiving antibiotics to take as a full course. CONCLUSIONS: We prioritised drug shops for intervention delivery to all drug shop staff and their customers to improve antibiotic stewardship. Knowledge deficits among these groups were notable and considered amenable to change using a SBCC intervention addressing improved health seeking behaviours, improved health literacy on antibiotic use, and provision of information on policy governing shops. Further intervention refinement should consider using participatory methods and address the impact on profit and livelihoods for drug shop staff for optimal compliance.

What contributes to inappropriate antibiotic dispensing among qualified and unqualified healthcare providers in Bangladesh? A qualitative study.

BACKGROUND: Over-prescribing and inappropriate use of antibiotics contributes to the emergence of antimicrobial resistance (AMR). Few studies in low and middle-income settings have employed qualitative approaches to examine the drivers of antibiotic sale and dispensing across the full range of healthcare providers (HCPs). We aimed to explore understandings of the use and functions of antibiotics; awareness of AMR and perceived patient or customer demand and adherence among HCPs for human and animal medicine in Bangladesh. METHODS: We used an ethnographic approach to conduct face-to-face, in-depth interviews with 46 community HCPs in one urban and one rural area (Gazipur and Mirzapur districts respectively). We purposefully selected participants from four categories of provider in human and veterinary medicine: qualified; semi-qualified; auxiliary and unqualified. Using a grounded theory approach, thematic analysis was conducted using a framework method. RESULTS: Antibiotics were considered a medicine of power that gives quick results and works against almost all diseases, including viruses. The price of antibiotics was equated with power such that expensive antibiotics were considered the most powerful medicines. Antibiotics were also seen as preventative medicines. While some providers were well informed about antibiotic resistance and its causes, others were completely unaware. Many providers mistook antibiotic resistance as the side effects of antibiotics, both in human and animal medicine. Despite varied knowledge, providers showed concern about antibiotic resistance but responsibility for inappropriate antibiotic use was shifted to the patients and clients including owners of livestock and animals. CONCLUSIONS: Misconceptions and misinformation led to a wide range of inappropriate uses of antibiotics across the different categories of human and animal healthcare providers. Low awareness of antibiotic action and antibiotic resistance were apparent among healthcare providers, particularly those with little or no training and those in rural areas. Specific and targeted interventions to address AMR in Bangladesh should include educational messages on the rational use of antibiotics and how they work, targeting all types of healthcare providers. While tailored training for providers may increase understanding of antibiotic action and improve practices, more far-reaching structural changes are required to influence and increase responsibility for optimising antibiotic dispensing among all HCPs.

Elevated levels of serum uric acid and insulin resistance are associated with nonalcoholic fatty liver disease among prediabetic subjects.

Background: Nonalcoholic fatty liver disease (NAFLD) is a hepatic manifestation of insulin resistance and serum uric acid (SUA) levels seemed to be elevated during this disorder. There is a paucity of data regarding the association of SUA with NAFLD in prediabetes. In this context, the present study has been undertaken to investigate this association. Methods: In a cross-sectional analytical design, a total of 110 prediabetic subjects [M/F; 63/47, age in ranges, 45 (25-68)] were recruited in the study and divided into non NAFLD (n = 62) and NAFLD (n = 48) group after examined with ultrasonogram. Insulin resistance (HOMA-IR) was calculated by homeostasis model assessment. Results: NAFLD subjects had significantly higher levels of SUA compared to non NAFLD subjects (6.10 ± 1.42 vs. 5.38 ± 1.14, p = 0.004). They also had significantly higher levels of HOMA-IR (2.4 ± 1.09 vs. 1.4 ± 0.45, p < 0.001). In binary logistic regression analysis, HbA1c (OR = 3.505, p = 0.002), SUA (OR = 1.514, p = 0.023) and HOMA-IR (OR = 1.478, p = 0.029) were found to be significant determinants of NAFLD after adjusting the effects of BMI and triglyceride (TG). In multiple linear regression analysis, SUA showed significant positive association with HOMA-IR (ß = 0.355, p = 0.027) and TG (ß = 0.325, p = 0.033) after adjusting the effects of BMI and HbA1c. Conclusions: Increased levels of serum uric acid are significantly associated with NAFLD and this association seemed to be mediated by insulin resistance among prediabetic subjects.

The Role of Selective Nerve Root Block in the Treatment of Lumbar Radicular Leg Pain.

The objective of this retrospective study was to investigate the clinical effectiveness of nerve root blocks (i.e., periradicular injection of Lidocaine and triamcinolone) for lumbar monoradiculopathy in patients with a mild neurological deficit in National Institute of Traumatology & Orthopaedic Rehabilitation (NITOR), Dhaka, Bangladesh from March 2014 to December 2014. We Included 24 patients (32-74 years) with a minor sensory/motor deficit and an unequivocal MRI finding (18 disc herniations, 6 foraminal stenosis) treated with a selective nerve root block. Based on the clinical and imaging findings, surgery (decompression of the nerve root) was justifiable in all cases. Seventeen patients (87%) had rapid (1-4 days) and substantial regression of pain, four required a repeat injection. Sixty percent (60%) of the patients with disc herniation or foraminal stenosis had permanent resolution of pain, so that an operation was avoided over an average of 6 months (2-9 months) follow-up. Nerve root blocks are very effective in the non-operative treatment of minor monoradiculopathy and should be recommended as the initial treatment of choice for this condition.

CRP (C-reactive protein) in Early Pregnancy Predictor for Development of GDM.

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.

Different Growth Patterns of Canine Prostatic Carcinoma Suggests Different Models of Tumor-Initiating Cells.

Controversies remain regarding the cell type from which human prostate cancer originates, and many attempts have been made to identify the cellular origin of canine prostate cancer but without definitive proof. This study aims to evaluate the expression of luminal (androgen receptor [AR], cytokeratin [CK]8/18) and basal (CK14, CK5) cell markers in different histologic subtypes of canine prostatic carcinoma (PC) and to suggest the most likely tumor-initiating cells. Normal prostates (n = 8) were characterized by AR+CK8/18+ luminal cells and few CK5+ basal cells, while CK14 was absent. Similar pattern was observed in all 35 prostates with benign prostatic hyperplasia, except few scattered CK14+ basal cells in 13 samples (37.14%). AR was localized in the nucleus of both normal and hyperplastic cells. In 34 samples of PC, the following growth patterns were identified: cribriform (44.12%), solid (32.35%), small acinar/ductal (20.59%), and micropapillary (2.94%). Most PCs expressed AR and CK8/18, while CK5 and CK14 expression was observed in 25% and 20% of cases, respectively. AR revealed a variable intracellular distribution, both nuclear and cytoplasmic. Solid PC was characterized by an undifferentiated or aberrant phenotype with a reduced expression of AR and CK8/18, increased number of CK14+ cells, and 7 antigen expression patterns. This study demonstrated a predominance of differentiated luminal cell types in canine prostatic tumors, although the role of basal cells in prostate carcinogenesis should also be considered. Moreover, few scattered CK5+ cells in AR+CK8/18+ tumors identified the existence of intermediate cells, from which neoplastic transformation may alternatively commence.

Diagnosis of common bacterial causes of urethritis in men by Gram stain, culture and multiplex PCR.

Urethritis is one of the most important causes of morbidity and mortality in developing countries. The aim of this study was to detect common bacterial causes of urethritis in men by Gram stain, culture and multiplex PCR.185 male patients who presented at the Skin and venereal clinic of the Dhaka Medical College, Bangladesh with clinical symptoms suggestive of urethritis were enrolled in this study. Urethral discharges were tested for detection of Neisseria gonorrhoeae by Gram stain, culture and PCR. Multiplex PCR assay was done to detect DNA of Chlamydia trachomatis, Ureaplasma urealyticum and Mycoplasma genitalium. Out of 185 participants, 30.27% and 14.6% were infected by Neisseria gonorrhoeae and Chlamydia trachomatis respectively. None of the individuals was found positive for either Ureaplasma urealyticum or Mycoplasma genitalium. Among the Neisseria gonorrhoeae positive patients 27.57% were positive from Gram stain, 26.49% were culture positive, 30.27% were positive by PCR (p<0.001). 32.65% of the Neisseria gonorrhoeae isolates were penicillinase producers and 83.67% were susceptible to ceftriaxone. Considering culture as the gold standard, the sensitivity and specificity of PCR for the detection of Neisseria gonorrhoeae was 100%, and 94.85% respectively with an accuracy of 96.22%. 3.73% of the 134 smear negative and 5.15% of the 136 culture negative samples were positive by PCR. PCR was the most sensitive and rapid method for the diagnosis of urethritis. Multiplex PCR may be a useful approach to laboratory diagnosis of urethritis in men for its high sensitivity and specificity.

Prevalence and distribution of different diarrhoeagenic Escherichia coli virulotypes in major water bodies in Bangladesh.

Escherichia coli, a prominent waterborne pathogen, causes a variety of gastrointestinal and extraintestinal infections that depend on virulence determinants. To monitor natural aquatic systems for virulence-associated genes of E. coli, multiplex PCR was used in a survey covering 46 major natural water bodies in Bangladesh. DNA was extracted directly from water samples as well as from pre-enriched and enriched cultures during three successive seasons and assessed for E. coli virulotype distribution. From the five virulotypes, genes from the enterotoxigenic (ETEC), enteropathogenic (EPEC), and enterohaemorrhagic (EHEC) virulotypes were detected consistently, but genes from the enteroinvasive (EIEC) and enteroaggregative (EAEC) virulotypes were traced only occasionally. ETEC was the most prevalent virulotype, followed by EPEC. However, EIEC and EAEC virulotypes could not be detected in winter or the rainy season, respectively. Specific regional distribution patterns of different E. coli virulotypes and their temporal fluctuations were identified. These observations may assist with assessing seasonal risk and identifying vulnerable areas of the country prone to E. coli-associated outbreaks.

Detection and Primary Analysis of Antibacterial Activity in the Ethyl Acetate Extract of Lantana camara L. Leaves.

Lantana camara L. is generally considered an invasive plant species throughout the world. Research works carried out in recent years have proved its significance as a source of antimicrobial lead molecules. The aim of this research was to identify the antibacterial substance(s) in this plant species found locally and to test its antibacterial effect against selected bacterial strains. Plant samples were collected from the University of Dhaka campus. Ethanol and ethyl acetate extracts of the plant leaves were tested against Escherichia coli, Bacillus subtilis, Pneumococcus and Klebsiella. Both the ethanol and the ethyl acetate extracts showed significant activity against Bacillus subtilis. In disk diffusion antibacterial assay, ethanol extract showed greater activity than ethyl acetate extract against Bacillus subtilis and the zones of inhibition were 14 mm and 12 mm respectively. However, ethyl acetate extract showed greater activity than ethanol extract in TLC bioautography assay. Ethyl acetate and ethanol extracts showed very little activity against Pneumococcus and Klebsiella, but no antibacterial potential against Escherichia coli. Fractionation of the ethyl acetate extract by TLC and bioautography detection of antibacterial activity in TLC encouraged further purification of the lead active compound(s). Phytochemical composition analysis of the ethyl acetate extract showed the presence of alkaloids, steroids, phenolic compounds and glycosides.

Use of Drugs Considering Route of Administration on Drug Prescription Pattern for Bronchial Asthma in a Tertiary Level Hospital.

Bronchial asthma is one of the much known long-term respiratory conditions. Incidence is increasing, in developing countries like Bangladesh. Cross-sectional type of observational study was carried out over one year (July 2017 to June 2018) in the department of Pharmacology with collaboration of the department of Respiratory Medicine and Medicine, Mymensingh Medical College and Hospital, Mymensingh, Bangladesh. A total of 160 patients were selected non-randomly for the study. Inhalation route (52.35%) was the most preferred one over oral route (47.65%). In total 245 drugs, 131 FDC drugs (Salmeterol + Fluticasone) were prescribed with inhalation therapy which is 53.46%, another 9 FDC drugs that is (Ipratropium bromide + Salbutamol) were prescribed with inhalation therapy which is 3.67%, 101 drugs (Salbutamol) were prescribed with inhalation therapy that is 41.23%, 4 drugs (Beclomethasone) were prescribed with inhalation therapy that is 1.64%. Majority of patient were taking inhalation form of anti-asthmatic drugs.

Label free flexible electrochemical DNA biosensor for selective detection of Shigella flexneri in real food samples.

An effective tool for early-stage selective detection of the foodborne bacterial pathogen Shigella flexneri (S. flexneri) is essential for diagnosing infectious diseases and controlling outbreaks. Here, a label-free electrochemical DNA biosensor for monitoring S. flexneri is developed. To fabricate the biosensor, detection probe (capture probe) is immobilized on the surface of poly melamine (P-Mel) and poly glutamic acid (PGA), and disuccinimidyl suberate (DSS) functionalized flexible indium tin oxide (ITO) electrode. Anthraquinone-2-sulfonic acid monohydrate sodium salt (AQMS) is used as a signal indicator for the detection of S. flexneri. The proposed DNA biosensor exhibits a wide dynamic range with concentration of the targets ranging from 1 × 10-6 to 1 × 10-21 molL-1 with a limit of detection (LOD) of 7.4 × 10-22 molL-1 in the complementary linear target of S. flexneri, and a detection range of 8 × 1010-80 cells/ml with a LOD of 10 cells/ml in real S. flexneri sample. The proposed flexible biosensor provides high specificity for the detection of S. flexneri compared to other target signals such as discrete base mismatches and different bacterial species. The developed biosensor displayed excellent recoveries in detecting S. flexneri in spiked food samples. Therefore, the proposed biosensor can serve as a model methodology for the detection of other pathogens in a broad span of industries.

Role of Mifepristone in Trial of Labour after Previous Caesarean Delivery in Intrauterine Fetal Death.

When a baby dies in utero, the options are either to wait for spontaneous labour or to induce it. An obstetrician, encounters with a perplexity of choosing a management plan when this worst situation of IUFD coalesced by history of previous caesarean delivery. The ideal drug for the termination should not only be efficacious and cost-effective, but also be convenient enough to avoid operative interference arising from a wasted pregnancy. The study was aimed to evaluate efficacy, safety and compliance of oral mifepristone in trial of labour in case of IUFD after previous caesarean section. This was a cross sectional descriptive type of observational study conducted in the Department of Obstetrics and Gynaecology, Mymensingh Medical College Hospital, Bangladesh from February 2018 to August 2018. Total 50 patients were selected purposively based on inclusion criteria and diagnosed as IUFD with previous caesarean delivery. The patients were received mifepristone once and reviewed after 48 hours and those who were not attained favourable Bishop's score were counseled for mechanical induction. Antibiotics and analgesia were administered according to requirement. Data analysis was done using SPSS version 22.0. All the 50 women received 200 mg oral mifepristone. Forty-four 44(88.0%) women was delivered vaginally among them 18(36.0%) were delivered following mifepristone induction only and 26(52.0%) required additional induction method. The earliest induction to delivery interval following mifepristone was 13 hours. Twenty eight (63.6%) cases were discharged within 72-120 hours. After 48 hours following induction there was significant improvement of Bishop's score. In this study 6(12.0%) out of 50 cases were reasoned for laparotomy and blood transfusion was required for them. There was no statistically significant difference according to gestational age in mode of delivery (p>0.05). There was no difference observed in mean induction to delivery interval between second and third trimester at 5% level of significance (p>0.05). In this study, the women showed drastic improvement in cervical score following induction with mifepristone and decreased repeat caesarean rate. Eventually, the length of agony of receiving dead baby was cut short without much more ailments. Hence, mifepristone may be considered as a safe, efficacious, convenient and cost-effective induction agent for labour induction in women with dead fetus in utero in previously scarred uterus.

Association of Low Vitamin D Level with Pelvic Organ Prolapse in Post Menopausal Women: A Case Control Study.

Pelvic organ prolapse refers to protrusion of the pelvic organ into or out of the vaginal canal. One in four women in the USA suffer from some type of pelvic floor disorder including pelvic organ prolapse and frequency of pelvic organ prolapse is more with increasing age. In Bangladesh, 15.6% women suffered from pelvic organ prolapse and more than 11.0% of women require surgical correction of prolapse in their life times. According to few researches, there is an observed association between low vitamin D levels with pelvic organ prolapse but this finding is not unequivocal. This case control study has been conducted in the Department of Obstetrics and Gynaecology, Bangabandhu Sheikh Mujib Medical University (BSMMU), Bangladesh from October 2018 to August 2020 to investigate the level of vitamin D in patients with and without pelvic organ prolapse to explore the association of low vitamin D with pelvic organ prolapse. A total 148 participants of 52 years or older attending the out or inpatient department were enrolled in the study. The study population was divided into two groups, a case group (n=74) consisting of patients with pelvic organ prolapse and a control group (n=74) comprising of women without pelvic organ prolapse. After taking informed written consent the serum vitamin D level of all participants was measured by CMIA technology with flexible assay protocols at Biochemistry and Molecular Biology department of the same institute. All necessary Data were collected on variables of interest by using the structured questionnaire pre-designed for interview, observation, clinical examination, and biochemical Data collection. Distributions were expressed by mean and standard deviation for continuous variables and by frequency and percentage for qualitative variables. Student's t-test and Chi square test were done to see the significance of differences between Group I and Group II. Odds ratio, correlation coefficient, and multivariate logistic regression analysis was done to assess the association of low vitamin D level with pelvic organ prolapse. Mean±SD level of Vitamin D in the case group was 13.96±5.18ng/ml and in the control group was 21.08±5.77ng/ml respectively. The difference was statistically significant (p<0.05). Moreover, the vitamin D levels were inversely proportionate with the severity of pelvic organ prolapse. OR (95% CI), of two groups showed risk of developing pelvic organ prolapse 5.63 times higher in women with decreased vitamin D level. Thus it can be concluded that women having low level of vitamin D have more chance of developing pelvic organ prolapse.

Procalcitonin versus C-Reactive Protein as a Biomarker for Prediction of Bacterial Infection in Children with Febrile Neutropenia in Acute Leukemia.

Febrile neutropenia (FN) is a frequently occurring treatment-related complication with significant morbidity and mortality for childhood acute leukemia. Early diagnosis and assessment of severity are essential steps for early comprehensive treatment to reduce FN-related morbidity and mortality. Biomarkers like C-reactive protein (CRP) and procalcitonin (PCT) can be used to assess and predict the bacterial infection in children with febrile neutropenia. The objective of the study was to determine the role of procalcitonin and CRP as a biomarker for prediction of bacterial infection in children with FN in acute leukemia. This prospective observational study was conducted in the Department of Pediatric Hematology and Oncology, Bangabandhu Sheikh Mujib Medical University (BSMMU), Bangladesh from August 2020 to July 2021. Total 58 Children with acute leukemia aged 1 to <18 years with FN were analyzed in this study. A proper history and thorough physical examination were carried out. The blood sample was sent for biomarkers (Procalcitonin and CRP) within 24 hours of the onset of FN and other investigations, such as Complete blood count, Blood C/S, Urine R/E and C/S. Metabolic workup (SGPT, Serum Creatinine, Serum Electrolytes, Serum Ca+) was also done in every patient. Stool R/E & C/S, Chest X-ray, Wound swab for C/S were done when the patient presented with diarrhoea, cough, respiratory distress and focal sepsis respectively. In this study, the mean age of the patients was 6.62±4.07 years (1.10-16.0 years) and 34 patients (58.6%) were male. In 65.5% of patients, localizing signs of infection were not identified. Of the 58 patients, 12 patients (20.7%) showed positive blood culture and 2 patients (3.4%) showed positive urine culture. Klebsiella spp (41.0%) was the most frequent organism isolated followed by Acinetobacter (17.0%), Pseudomonas (17.0%) and E. coli (17.0%). The median PCT levels were significantly higher in patients with bacterial infection than patients without bacteremia (26.10µg/l versus 0.78µg/l, p=0.002) and PCT level >2µg/l was significantly associated with bacteremia. The median CRP levels in the bacteremia and without-bacteremia patients were 137.4mg/L and 54.17mg/L, respectively (p=0.036). In direct comparisons, PCT showed better overall performance than CRP with the AUC being 0.797 (95% CI 0.651-0.943) for PCT and 0.697 (95% CI 0.54-0.855) for CRP in predicting the bacterial infection. PCT and CRP both are useful biomarkers for the prediction of bacteremia, but PCT may be a superior early biomarker as compared to CRP to predict bacterial infection in children with febrile neutropenia in acute leukemia.

Knowledge, Attitude and Practice of Undergraduate Medical Students of Bangladesh Regarding COVID-19 and its Vaccination.

Medical students are one of the socially active, reliable, and persuading population of information, prevention and control, and incentive of vaccination to stop the current pandemic situation. Consequently, knowing the status of medical students' knowledge, about symptoms, and transmission of disease, prevention of COVID-19 and their attitudes towards a vaccine is important. This multi-center cross-sectional descriptive study was one of the first ones in Bangladesh among the undergraduate medical students who completed pathology, microbiology, and pharmacology. The study was conducted from March to April 2021, using a convenience sampling method in twelve government and non-government medical colleges. Among 1132 who completed the questionnaire, and 15 students from different centers were excluded from the pre-testing and face validation. The age of the 1117 respondents were 22 to 23 years, of which the majority of the respondents were female 749 (67.0%), and 368 (33.0%) were male. Almost all participants had correct knowledge (84.1%) about the symptoms of COVID-19. But 59.2% had wrong knowledge about transmission of disease by an afebrile person. Above 60.0 % of the participants have worn a facial mask when contacting people, refrained from shaking hands, washed hands, avoided people with signs and symptoms suggestive of COVID-19, and avoided crowded places as a practice of prevention. 37.6% of medical students showed positive attitudes about the participation of management of a COVID-19 patient. Most of the participants' decided to have a vaccine depending on its availability. But 31.5% had trust in natural immunity rather than vaccination. Most undergraduate Medical college students understood the basic information, possessed a positive attitude, and presented good practice towards the COVID-19 and vaccination. They play a crucial role in motivation and acceptance of vaccines among the general citizen to fight back against the pandemic in the country with limited resources.

Immunohistochemical characterization of phagocytic immune cell infiltration into different adipose tissue depots of dairy cows during early lactation.

The present study aimed to investigate whether phagocytic immune cells infiltrate into bovine adipose tissue (AT) and to study the effects of lactation and conjugated linoleic acid (CLA) supplementation on the invasion of phagocytic immune cells into different s.c. and visceral (v.c.) fat depots of primiparous dairy cows during the first 105 d in milk (DIM). German Holstein-Friesian cows (HF; n = 25) with a mean body condition score of 3.0 were divided into a control (CON) and a CLA group. From 1 DIM until sample collection, CLA cows were fed 100 g of CLA supplement/d (about 6% of c9,t11 and t10,c12 isomers each), whereas the CON cows received 100 g/d of a fatty acid mixture instead of CLA. The CON cows (n = 5 each) were slaughtered at 1, 42, and 105 DIM, and the CLA cows (n = 5 each) were slaughtered at 42 and 105 DIM. Adipose tissues (n = 150) from 3s.c. (tailhead, withers, and sternum) and 3 v.c. (omental, mesenteric, and retroperitoneal) depots were sampled. In addition, s.c. tailhead biopsies were collected by repeated surgical biopsies (3 samplings within 7 wk; n = 36) from 12 nonpregnant, nonlactating Simmental heifers (SM; mean body condition score = 5.0) fed diets of varying energy density to compare the changes in phagocytic immune cell infiltration with early lactating cows. Immunohistochemical analyses of different fat depots revealed a low incidence of phagocytic immune cell infiltration in early lactating cows. The portion of infiltrating macrophages (CD68+) in a few positive AT samples of HF cows was slightly lower in s.c. than v.c. fat and was positively correlated with both empty body weight and adipocyte size. However, no differences with regard to DIM and CLA supplementation were observed in HF cows. Increased accumulation of phagocytic immune cells, albeit at low cell numbers, in nonpregnant, over-conditioned SM heifers might be related to larger adipocytes secreting higher amounts of chemoattractant adipokines compared with the early lactating cows. In conclusion, the extent of fatness in HF cows may not be high enough to stimulate significant infiltration of phagocytic cells in AT and, therefore, these immune cells might have no major role in the immunologic and metabolic adaptations of AT during early lactation.

Effects of third trimester counseling on pregnancy weight gain, birthweight, and breastfeeding among urban poor women in Bangladesh.

BACKGROUND: Maternal malnutrition and poor gestational weight gain are the most important causes of low birth weight and high rates of newborn mortality. OBJECTIVE: To assess the effects of nutrition counseling in the third trimester of pregnancy on maternal weight gain, birth weight of newborn, and breastfeeding practices. METHODS: This was a longitudinal experimental study with nutrition intervention for a period of 3 months. One hundred fifteen women (57 in the intervention group and 58 in the comparison group) who were visiting the Maternal and Child Health Training Institute at 6 months of pregnancy were randomly selected. The intervention group was given nutrition education twice in the first month and once a month for the next 2 months before delivery; the comparison group received routine hospital advice on food intake, immunization, personal hygiene, and breastfeeding. The women were weighed monthly up to delivery, the newborn infants' birth weights were measured within 24 hours after delivery, and breastfeeding practices were observed 1 month after delivery. RESULTS: Women in the intervention group gained 1.73 kg more weight during the third trimester than women in the comparison group (5.61 vs. 3.88 kg, p < 0.001). The mean birthweight of babies of women in the intervention group was 0.44 kg greater than that of babies of women in the comparison group (2.86 vs. 2.42 kg, p < 0.001). In the intervention group, 10.5% of babies were born with low birthweight, compared with 48.3% of the babies of women in the comparison group (p < 0.001). In the intervention group, 75.4% of mothers initiated breastfeeding within 1 hour after birth, compared with 34.5% of mothers in the comparison group (p < 0.001). CONCLUSIONS: Nutrition education only during the third trimester improved weight gain during pregnancy, reduced 78% of low birth weight, and improved breastfeeding practices.

Efficacy of Carbetocin versus Oxytocin for the Prevention of Primary Post Partum Haemorrhage after Caesarean Section in Mymensingh Medical College Hospital, Bangladesh.

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.
