RESUMO
A baby's weight at birth is an important predictor of infant growth and survival. Low birth weight leads to an impaired growth of the infant and its attendant risks of a higher mortality and morbidity. Various studies found higher maternal plasma homocysteine level was associated with lower offspring birth weight. Therefore, this study was carried out to find out association between maternal serum homocysteine and birth weight. A cross sectional study was conducted in the Department of Obstetrics and Gynaecology, BSMMU from September 2018 to August 2019. Pregnant women at their third trimester between 37-40 weeks admitted to in patient Department of Obstetrics and Gynaecology, BSMMU were included in this study. Ethical committee clearance was obtained from the institution. After matching eligibility criteria informed written consent were taken from the patients. Data was collected from the patients using the structured design by interview, observation, clinical examination and haematological investigations. The serum homocysteine level of these patients and birth weight of their babies was measured immediately after delivery. Negative correlation was found between maternal serum homocysteine level and neonatal birth weight, (r = -0.419, p<0.05). During regression analysis maternal homocysteine and gestational age was found significant when adjusted with maternal age, parity, maternal BMI and sex of the baby. So, increased maternal serum homocysteine is negatively associated with low birth weight babies.

Self- rated health (SRH) is a valuable screening-level measure of a community's health status. A better understanding of the factors that influence SRH is time-demanding and challenging. This study aims to examine the determinants of SRH by investigating health morbidities, demographic and socio-economic factors in Bangladesh perspective. This cross-sectional study was conducted among 908 adults (aged 18 years and above) in Manikganj district of central Bangladesh from 2nd January to 13th January 2017. Chi-square test was performed to test the association and binary logistic regression was performed to predict the relationship of SRH with all potential variables. The present study reveals the balance of bad health versus good health which was 27.2% and 72.8% respectively. Participants had at least one or more chronic diseases reported 3.40 times (p<0.001) bad health compared to those who did not have any chronic illness. In contrast, acute morbidity was not a significant determinant for SRH (OR=1.379, p=0.063). Older population aged 60 years and above had 3.96 times (p<0.001) higher chance of having self-reported bad health than the younger population. In addition, depression was also found a significant contributor (OR=2.05, p<0.001) to bad health. Chronic morbidity, older age and depression are the significant predictors of SRH. If SRH is used as a screening-level measure for the rural communities then the chronic disease status of rural Bangladesh will be identified quickly and easily.

BACKGROUND: Abiotic stressors impair crop yields and growth potential. Despite recent developments, no comprehensive literature review on crop abiotic stress assessment employing deep learning exists. Unlike conventional approaches, deep learning-based computer vision techniques can be employed in farming to offer a non-evasive and practical alternative. METHODS: We conducted a systematic review using the revised Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement to assemble the articles on the specified topic. We confined our scope to deep learning-related journal articles that focused on classifying crop abiotic stresses. To understand the current state, we evaluated articles published in the preceding ten years, beginning in 2012 and ending on December 18, 2022. RESULTS: After the screening, risk of bias, and certainty assessment using the PRISMA checklist, our systematic search yielded 14 publications. We presented the selected papers through in-depth discussion and analysis, highlighting current trends. CONCLUSION: Even though research on the domain is scarce, we encountered 11 abiotic stressors across 7 crops. Pre-trained networks dominate the field, yet many architectures remain unexplored. We found several research gaps that future efforts may fill.

The world has been devastated facing the outbreak of a novel infectious disease known as Corona virus disease (COVID-19). This has been declared as a pandemic by the World Health Organization. The frontline health care workers, who are directly involved in the diagnosis, treatment and care of patients with COVID-19, are taking significant personal risks on their own health and those of their family members. Objectives of the study include establishing the physical, psychological and social impact experience by the healthcare workers serving in public hospitals of Bangladesh. This prospective cross-sectional observational study was carried out at Kuwait Bangladesh Friendship Government Hospital, the first Covid-19 designated hospital of Bangladesh between the 1st June and the 31st August, 2020. A total of 294 doctors, nurses, ward boys and ailed healthcare workers were included in this study via purposive sampling. The study found statistically significant (p value 0.024) difference of medical co-morbidities between Covid-19 positive and Covid-19 negative groups of health care professionals. Significant association was found between duration of work and presence during aerosol generating procedure with COVID infectivity of the study subjects. 72.8% respondents experienced public fear of contracting the virus from them and 69.0% noticed negative attitude of the society towards them. Eighty five percent (85.0%) did not get any community support during this pandemic crisis. The health care professionals engaged in COVID-19 treatment have been taking significant personal risk on their life in terms of physical, psychological and social perspective. Providing safeguard to the health care workers are integral components of public health measures for addressing the COVID-19 pandemic. Special interventions to promote their physical wellbeing and arrangement of adequate psychological training need to be immediately implemented to cope up this critical situation.

The objective of this study was to figure out the prevalence and probable causes of repeat breeding (RB) in dairy cows. Hence, a cross-sectional study was conducted on randomly selected 265 dairy farms in Sirajganj, Bogura, Rangpur, Satkhira, and Munshiganj districts of Bangladesh from December 2018 to February 2019. Data were collected through a direct interview method using a survey questionnaire. The reproductive organs of repeat breeder cows were examined for pathological, infectious, and functional reasons, and genital tract abnormalities. Additionally, the influence of nutrition, season, and age on the frequency of RB was recorded. The prevalence of RB was 28% among the 3824 cows investigated. Among the total repeat breeder cases, 72.54% of RB cases were found in Holstein-Friesian crossbred, 23.90% in Jersey crossbred, 1.50% in Sahiwal crossbred, and 2.06% in indigenous cows. The prevalence of RB was significantly highest (P < 0.01) in Satkhira (44.35%) and lowest in the Munshiganj district (15.87%). Data indicated that a major proportion of cows significantly (P < 0.05) faced RB problems due to functional causes (34.18%), followed by pathological causes (28.01%), genital tract abnormalities (21.32%), and infectious causes (16.49%). Furthermore, the cows were remarkably (P < 0.001) affected in RB during the summer season and nutritional deficient diseases like milk fever (70%). Age (3-7 years) had a significant (P < 0.001) effect on the RB occurrence (90%) in crossbred cows. However, particular focus should be given to systematic breeding, balanced nutrition, artificial inseminator efficiency, and hygienic inseminating tools to reduce RB incidence in high-yielding crossbred cows.

Hypospadias is a developmental defect of male urethra characterized by absence of meatal opening at the tip of glans but is present at the ventral surface of penis anywhere along the shaft, even in the perineum. Usually this defect is associated with ventrally curved penis. Surgery is the single option to correct this birth defect. More than 300 techniques have been developed but none is universally acceptable as because, surgery is usually associated with fistula. Rate of fistula formation varies from technique to technique. Now a day, Snodgrass technique is widely practiced because of its low rate of fistula formation. Many factors are responsible for this post-operative complication. Most important one is developmentally defective ventral penile skin where some local factors like vascular and collagen tissues are insufficient. This observational study was performed to evaluate the role of dorsal vascular flap over the neourethra following urethroplasty by Snodgrass technique in terms of post-operative fistula formation in the Department of Paediatric Surgery, Bangabandhu Sheikh Mujib Medical University, Dhaka, Bangladesh from March 2018 to March 2020. A total of 39 patients with distal penile hypospadias were included in this study. All underwent Snodgrass urethroplasty with additional dorsal vascular flap over the neourethra to support this ventrally deficient local factor. The outcome in terms of post operative urethrocutaneous fistula was evaluated. Only two patients (5.15%) developed urethrocutaneous fistula. In conclusion, addition of dorsal vascular flap over the neourethra by Snodgrass technique reduces the rate of the fistula formation.

Coronary artery disease (CAD) is the leading cause of death in developed and developing countries. Associated co-morbidities like diabetes, hypertension and obesity are making the situation worse. WHO enlisted obesity as an epidemic which also affects a great number of young population. Some recent studies showed the presence of an apparent paradoxical relationship between obesity and cardiovascular prognosis in certain subsets of patents. As BMI is an established marker of obesity; an attempt has been made to assess relationship between BMI and angiographic severity of coronary artery disease in Acute Coronary Syndrome (ACS) patients of Bangladeshi origin. To assess the association between body mass index and angiographic severity of coronary artery disease in patients with acute coronary syndrome; this cross sectional analytical study was conducted in the Department of Cardiology, Mymensingh Medical College Hospital (MMCH) and Bangabandhu Sheikh Mujib Medical University (BSMMU) from December 2016 to February 2018 among purposively selected 65 patients. Relevant ethical issues were taken into consideration. Coronary angiogram was done in the same index hospitalization period. After coronary angiogram performed patients were grouped into two groups according to their BMI. Patients with BMI <25kg/m² as Group I and those ≥25kg/m² as Group II. Angiographic severity of coronary artery disease was assessed by vessel score and Syntax score. Mean age of Group I was 54.45±10.42 years, while in Group II it was 50.76±8.89 years reflecting the early presentation of higher BMI patients. Male to female ratio was 12:1. Mean BMI of Group I and Group II was 22.56±1.59 and 28.67±2.64 respectively. In Group I, 10(25.0%) had single vessel lesion, 15(37.5%) had double vessel lesion and 14(35.0%) had triple vessel lesion, while in Group II, 6(24.0%) had single vessel lesion, 12(48.0%) had double vessel lesion and 5(20.0%) had triple vessel lesion. Mean Syntax score of Group I and Group II was 13.18±8.45 and 10.42±7.14 respectively. Patients in the increasing BMI class had a higher prevalence of diabetes, hypertension and dyslipidaemia. A negative correlation was observed between BMI and angiographic severity (Vessel score, Syntax score and HRCA e.g. LM disease) of CAD indicating that patients with higher BMI had a lower coronary artery disease (CAD) severity than their normal BMI counterparts. Patients with high BMI have a lower CAD severity than usually expected. After adjustment for co-morbidities, BMI was not found as an independent predictor of severity of coronary artery disease.

The history of ascariasis is very old. It is endemic in various parts of Bangladesh. Hepatobiliary ascariasis is a well-known complication of the intestinal ascariasis. Although cosmopolitan, it predominantly affects people in Asia, Africa, and South America. This was a prospective observational study conducted from July to December 2014 to explore the short term outcome of therapeutic ERCP in the treatment of biliary ascariasis in a tertiary care hospital of Bangladesh. A total of 60 cases of biliary ascariasis were selected conveniently in this study. Data were collected by face-to-face interviews and observation with the help of data sheet. Data were checked for quality control and analyzed by computer using SPSS software. The mean±SD age of the patients was 30.96±7.66 years. All the patients were aged between 17 and 55 years and predominantly affect women in the 3rd and 4th decades. The most common presentation was upper abdominal pain in 47(83.32%) of the patients. Ultrasound was the diagnostic tool of choice, where biliary ascariasis was found in 40(66.7%) of patients. ERCP is reserved mainly for therapeutic purposes and found successful in 57(95%) of the patients.

The emergence of antibiotic resistant bacteria is a major health concern worldwide in recent years. The objective of this study is to establish the larvae of the silk moth (commonly known as silkworm), Bombyx mori as an infection model to study antibacterial effect of antibiotics against Klebsiella pneumoniae. In this study, the pathogenicity of a K. pneumoniae strain isolated from food to silkworm larvae was examined. Within 72 h of bacterial injection, all silkworm larvae were killed in a dose-dependent manner with their body color turning into black due to increased melanization. Bacterial numbers in the larval hemolymph (blood) significantly increased after 9 h of infection with a decrease in viable circulatory hemocytes in hemolymph. When presented with bacteria laden leaves, larvae did not eat but injection of bacteria directly into the midgut killed larvae within 12 h with a higher load required in comparison to that required for the killing by hemolymph injection. Administration of four different antibiotics into larval hemolymph showed therapeutic effect at different doses with varying efficacies against hemolymph-injected K. pneumoniae. These results indicate that the silkworm larvae can be used as an infection model not only to study the pathogenicity of K. pneumoniae but also to perform rapid screening for the identification of antibiotics effective against multidrug-resistant strains of K. pneumoniae.

Atherosclerosis is the pathognomic sign of ischaemic heart disease. Inflammation of the coronary artery contributes to the development of atherosclerosis. Neutrophil-to-lymphocyte ratio (NLR) has been reported to predict the risk of CAD and associated events in patients with ST-Segment elevation myocardial infarction (STEMI). This study was done to investigate the role of neutrophil-to-lymphocyte ratio (NLR) in predicting in-hospital adverse cardiac events in patients with STEMI thrombolysed with streptokinase (STK). This cross sectional descriptive type of study was conducted in the Department of Cardiology, Mymensingh Medical College Hospital, Mymensingh, Bangladesh from August, 2017 to October, 2018. The STEMI patients, thrombolysed with STK had blood samples at admission, analyzed for complete blood counts and NLR calculated. They were grouped into two, low and high NLR, taking 4.50 as cut-off value. Chi square test was used to compare rate of adverse events and death in hospital stay. Logistic regression analysis was used to estimate predictive ability of NLR for in-hospital cardiac events. A total of 87 (39.90%) patients had complications. Patients in high NLR group had higher rate of complications (48.3% vs. 22.5%, p<0.001) in hospital than those in low NLR group. Arrhythmias (21.1% vs. 9.9%, p<0.041), heart failure (27.9% vs. 14.1%, p=0.024), cardiogenic shock (16.3% vs. 4.2%, p<0.011), death (6.8% vs. 2.8%, p=0.227), re-infarction /post MI angina (4.1% vs. 0.0% p=0.084) occurred more in high NLR group. Mean NLR was significantly different between Group I and Group II (3.11±0.84 vs. 10.20±6.08, p<0.0001). Multivariate regression analysis showed NLR an independent predictor of in-hospital adverse cardiac events (p<0.0001). High on admission NLR is an independent predictor for in-hospital adverse cardiac events in patients with STEMI thrombolysed with streptokinase.

BACKGROUND: Here, we have shortly reported the recent updates on the disastrous progressions of the deadly delta variant and a virulent coinfection or post-COVID-19 infection of black fungus in India and its neighbouring countries. METHODOLOGY: We searched by utilizing appropriate keywords in Google Scholar, PubMed and other scholarly databases alongside several national and international newspapers to collect the latest data regarding the targeted topic. RESULTS: Recently, the delta variant is wreaking havoc in India, UK, and other countries around the globe and has also exhibited successful infections in around 20 to 55% of the people who have already recovered from COVID-19 originating from the different strains. Besides, a significant catch is the prevalence of 85.5% and 64.11% of Mucormycosis infections being co-morbid with COVID-19 and diabetes, respectively in South-Asian regions. CONCLUSIONS: To avert the emergence of an epidemic amid the pandemic, prompt actions from concerned authorities are warranted. Proper education on black fungus infection and associated risks from the COVID-19 and diabetes, adequate public awareness, and sufficient healthcare assistance to battle such fungal infections effectively should be ensured as quickly as possible.
RESUMO
In 2008, we published the first set of guidelines for standardizing research in autophagy. Since then, this topic has received increasing attention, and many scientists have entered the field. Our knowledge base and relevant new technologies have also been expanding. Thus, it is important to formulate on a regular basis updated guidelines for monitoring autophagy in different organisms. Despite numerous reviews, there continues to be confusion regarding acceptable methods to evaluate autophagy, especially in multicellular eukaryotes. Here, we present a set of guidelines for investigators to select and interpret methods to examine autophagy and related processes, and for reviewers to provide realistic and reasonable critiques of reports that are focused on these processes. These guidelines are not meant to be a dogmatic set of rules, because the appropriateness of any assay largely depends on the question being asked and the system being used. Moreover, no individual assay is perfect for every situation, calling for the use of multiple techniques to properly monitor autophagy in each experimental setting. Finally, several core components of the autophagy machinery have been implicated in distinct autophagic processes (canonical and noncanonical autophagy), implying that genetic approaches to block autophagy should rely on targeting two or more autophagy-related genes that ideally participate in distinct steps of the pathway. Along similar lines, because multiple proteins involved in autophagy also regulate other cellular pathways including apoptosis, not all of them can be used as a specific marker for bona fide autophagic responses. Here, we critically discuss current methods of assessing autophagy and the information they can, or cannot, provide. Our ultimate goal is to encourage intellectual and technical innovation in the field.

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.

Anorectal malformations (ARM) incorporate a broad spectrum of diseases, can affect both sexes, and involve the distal anus and rectum as well as the uro-genital tracts. Defects range from the minor which can be treated easily with an excellent outcome, to those are complex and often associated with other anomalies are difficult to manage with poor functional prognosis. This study was done to observe the hospital incidence of Anorectal malformations, frequency of types, sex distribution and spectrum of associations with ARM. The effects of presence of associated anomalies on morbidity and mortality also observed. Detailed history, clinical examinations and relevant investigations were performed for the primary and as well as the associated anomalies. A total of 80 patients were admitted in the department of pediatric surgery in Mymensingh Medical College Hospital during the period of June 2016 to May 2017. Age of the patients was ranging from 1-180 days with the mean age of 0.49±1.002 months. Male: Female ratio was 1.6: 1. Among them 48(60%) were high and 32(40%) were low variety of ARM. In male 37(46.2%) had high and 13(13.7%) were low variety whereas in female 11(13.7%) were high and 19(23.7%) had low ARM. Associated anomalies were seen in 25(31.2%) patient -18 in males and 7 in females; 20 in high and 5 in low ARM. Associated anomalies were uro-genital 11(13.8%), cardiovascular 10(12.5%), vertebral 4(5%), limb defects 3(3.5%) and others 2(2.5%). Four patients have more than one anomaly. Anorectal malformations occur more in boys than girls. Males were more likely to have high lesions and without fistula was the common defect. Low variety ARM were found more in females with Anovestibular fistula is the commonest defect. The most common associated anomalies were recto urinary fistula (13.8%). Associations were more in high than low ARM but not significant (p>0.05). Post operative complications were more in high ARM in both sexes with associated anomalies. The effects of types and associations on morbidity and mortality were significantly different (p<0.05).

Acute myocardial infarction has many risk factors and etiologies. Different factors are responsible for adverse in-hospital outcome after acute MI. Status of plasma vitamin D level has been found to be a good predictor of future adverse cardiovascular outcomes in patients with acute MI. Plasma vitamin D level has been considered as a potential marker for identifying individuals under risk of CAD and associated events. This study was done to investigate the role of plasma vitamin D level in predicting in-hospital adverse cardiac events in patients with acute MI. This cross sectional descriptive type of study was conducted in the cardiology department of Mymensingh Medical College Hospital, Mymensingh, Bangladesh from October 2017 to March 2019. Total 257 patients of first attack of acute MI were included considering inclusion and exclusion criteria. Fasting blood samples were analyzed for plasma vitamin D level. Sample population were grouped at first into two, normal and low vitamin D level, taking 30ng/ml as cut-off value, low vitamin D level is further subdivided into insufficiency (21-29ng/ml), deficiency (10-20ng/ml) and severe deficiency (<10ng/ml). Adverse in-hospital cardiac outcomes were observed. In-hospital adverse outcomes occurred in 42.9% patients having normal vitamin D level (>30ng/ml), 66.2% of patients having vitamin D insufficiency (21-29ng/ml), 78.2% of patients having vitamin D deficiency (10-20ng/ml) and 94.4% patients having severe vitamin D deficiency (<10ng/ml), which was statistically significant (p<0.05). Heart failure (30.3%, 47.7%, 63.6% and 77.8%, p<0.05), cardiogenic shock (12.6%, 27.7%, 34.5% and 33.3%, p<0.05), Arrhythmias (14.3%, 21.5%, 23.6% and 22.2%, p>0.05), death (2.5%, 0%, 3.6% and 11.1%, p>0.05) occurred more in low vitamin D groups. Mean vitamin D level was significantly different between Group I and Group II (42.59±10.08 vs. 18.64±6.54, p<0.0001). Multivariate regression analysis showed vitamin D is an independent predictor of in-hospital adverse cardiac events (p=0.001). Age (p=0.001) and obesity (p=0.048) were also other predictors of in-hospital adverse cardiac events. Low plasma vitamin D level is an important predictor for in-hospital adverse cardiac events in patients hospitalized with first attack of acute MI.

OBJECTIVE: Encephalitis is a disease that has a major impact on health systems worldwide in terms of mortality, morbidity and costs. Furthermore, it is a challenging disease for the treating physician, as the patient presentation varies, and not all patients present with typical complaints. In addition, if left untreated or if there is a delay in the treatment, the mortality rate due to encephalitis can increase. The incidence of encephalitis in Pakistan is scarce in the literature because, in most of cases, the specific cause is not evaluated due to lack of resources and also because the majority of cases are not reported. The aim of this study was to determine the incidence and outcomes of encephalitis in patients admitted to a tertiary care hospital intensive care unit in Pakistan. METHODS: This retrospective study was conducted in the intensive care unit of the Aziz Fatimah Medical College and Hospital, Faisalabad. After obtaining the ethical approval, a total of 75 patients were found in the medical records with a confirmed diagnosis of encephalitis out of total 3,921 patients admitted to the intensive care unit in the 5-year period from 1st January 2013 to 31st December 2018. RESULTS: The most common clinical presentation were seizures (64%) followed by headache (53%), irritability (29.3%) and hemiparesis (26.7%). Among all patients, 44 needed invasive ventilation, and 7 required non-invasive ventilation. In addition, the outcomes were variable. CONCLUSION: The incidence of encephalitis was 1.9% in the 5-year period, and the mortality rate was 37.3%. Also, 6.7% patients improved without any complications.
RESUMO
The coronavirus disease (COVID-19) is highly pathogenic viral infection caused by SARS-CoV-2. Currently, COVID-19 has caused global health concern. WHO has declared COVID-19 as a pandemic disease on March 11, 2020 and characterized by fever, dry cough, fatigue, myalgia and chest pain with pneumonia in severe cases. The virus has spread to at least 213 countries and more than 9093827 confirmed cases and 471490 deaths have been recorded. In the beginning, the world public health authorities tried to eradicate the disease in China through quarantine but are now transitioning to prevention strategies worldwide to delay its spread. There are some newly developed and promising methods for detection of SARS-CoV-2, in order to facilitate the development of novel approaches for early diagnosis. Nucleic acid based tests currently offer the most sensitive and early detection and confirmation for SARS-CoV-2 infection. Among them Real-time reverse transcription polymerase chain reaction (rRT-PCR) is the most popular and the "gold standard" testing method for the detection of SARS-CoV-2. The present study was carried out to detect 2019-Novel Coronavirus (2019-nCoV) by rRT-PCR method at Mymensingh Medical College, Mymensingh, Bangladesh from 1st April, 2020 to 31st May, 2020. A total of 14356 samples were tested from four districts of Mymensingh division namely, Mymensingh, Jamalpur, Sherpur, Netrokona and some parts of Sunamganj for rRT-PCR. Among them 1086 (7.5%) patients were positive for SARS-CoV-2. Out of 1086 positive cases 716(65.9%) were male and 370(34.1%) were female with a Mean±SD age 34.1±12 years. Maximum positivity was found in Mymensingh district followed by Netrokona, Jamalpur, Sherpur and Sunamganj respectively. This is the first base line study for genetic detection of 2019-nCoV in Mymensingh division which may reflect the total scenario of Bangladesh situation. We hope this paper will help the researcher to increase the availability, accuracy, and speed of widespread COVID-19 testing throughout the world in this crisis moment.

The increasing clinical incidence of antibiotic resistance in bacteria is a major global health care issue. Rampant use of antimicrobials is one of the major reasons of the dramatic rise in antibiotic-resistant bacterial strains. Suitable animal models are required to improve our understanding of bacterial pathogenicity, evolution and search for novel antibiotics. The larvae of the silk moth (commonly called silkworm), Bombyx mori, have been used as an animal model for testing the pathogenicity of a clinically isolated strain of enterohemorrhagic Escherichia coli O157:H7 upon injection through hemolymph. Here, we show that a foodborne E. coli O157:H7 strain can kill silkworm larvae upon injection through either hemolymph (blood) or midgut. Bacterial number in the hemolymph started to increase after 3 h of injection into hemolymph, while the number of viable circulating hemocytes decreased. Administration of four well-known antibiotics into the larval hemolymph up to 100 µg per larva showed therapeutic effect with varying efficacies against E. coli O157:H7 with ceftriaxone and imipenem showing better effect. Our findings indicate that silkworm larvae can be used as an animal model to screen for novel antibiotics that are effective against E. coli O157:H7.

Pregnancy is accompanied by changes in the maternal lipoprotein metabolism that may serve to satisfy the nutritional demands of the fetus in addition to the energy requirements of the mother. Early pregnancy is considered the anabolic phase, characterized by increased hepatic production of triglycerides and enhanced removal of triglycerides from the circulation, resulting in an increased deposition of fat in maternal adipose tissue. Late pregnancy is referred to as the catabolic phase, the release of free fatty acids from adipocytes is enhanced due to both relative insulin resistance and stimulation of hormones. Although it is known that cholesterol rises in pregnancy, at present it is not routinely measured or treated. However, a growing body of evidence from animal and human studies suggests adverse consequences of high cholesterol levels in pregnancy. High lipid profile, a major factor behind atherosclerosis may leads to unconsciousness. To avoid such problems during pregnancy this longitudinal study was carried out in the department of Biochemistry, Mymensingh Medical College in co-operation with the Department of Obstetrics and Gynecology, Mymensingh Medical College Hospital and Community Based Medical College Hospital, Bangladesh from July 2011 to December 2012 to compare the changes in high density lipoprotein cholesterol level during 2nd and 3rd trimester of pregnancy. A total of one hundred subjects were participated in this study comprising of second and third trimester of pregnancy. All subjects were made to fast overnight at least for a minimum of 8 hours. Blood samples were taken and analyzed by enzymatic colorimetric kit method. Pregnancy has been found to be associated with changes in lipid profile and this differs with each trimester. The average results were analyzed with respect to each pregnancy for the whole group. The study proves that serum High Density Lipoprotein (HDL) cholesterol increases in second trimester (48.71±7.61mg/dl) than third trimester (47.01±7.45mg/dl) of Pregnancy. So, Lipid profile estimation and monitoring should be made as a part of routine investigation during antenatal period.
