An Alarming Rise of Candidemia Caused by Non-Albicans Candida Species in Intensive Care Unit in Mymensingh, Bangladesh

In Intensive Care Units (ICUs) infection represents the most frequent complication leading to high mortality. Particularly the incidence of fungal infections, especially due to Candida spp., has been increasing during the last years. Over last two decades there is predominance of Non albicans Candida (NAC) infection with increased isolation of novel species and decreased susceptibility. Early identification of Candida species and determination of antifungal susceptibility pattern is essential for effective management. Therefore, the study was conducted to isolate and identify Candida species from the blood samples of the patients suspected of candidemia and assess their antifungal susceptibility pattern. This cross-sectional, descriptive type of observational study was conducted in the Department of Microbiology, Mymensingh Medical College, Bangladesh from March 2021 to February 2022. Venous blood was collected from clinically suspected patients admitted at ICU, Neonatal Intensive Care Unit (NICU), Mymensingh Medical College Hospital, Bangladesh. Primary blood culture was performed by automated method followed by sub-culture in Saboraud's Dextrose Agar (SDA) and blood agar media. Candida species were recognized by phenotypic and genotypic methods. Antifungal susceptibility testing was done by disk diffusion and broth microdilution method (BMD). Out of 125 blood specimens collected, Candida species were isolated from 39(31.0%) blood samples of which NAC species were 35(89.0%) whereas C. albicans was only 4(10.2%). Eight (8) different Candida species were identified of which C. parapsilosis was predominant 16(41.0%). Rare and emerging drug resistant species of C. ciferrii 23.0%, C. auris 7.7%, C. rugosa 10.3%, C. lusitaniae 2.6% were also isolated. Candidemia was highest in neonate 33(84.61%) with male predominance 24(61.54%). Use of broad-spectrum antibiotics, prolonged hospital stay, pre-maturity and low birth weight (LBW) were found to be important risk factors. In candidemia the highest resistance was to Fluconazole-33% and lowest to Voriconazole-5%. The study showed that NAC species were more common with emergence of rare and multidrug resistant species.

Digital Gangrene is a Rare Presentation of Takayasu's Arteritis

Takayasu's arteritis is a chronic large vessel vasculitis that mainly affects the aorta and its major branches such as brachiocephalic, carotid, subclavian, vertebral, renal, coronary and pulmonary arteries. It most commonly occurs in female at child bearing age and female to male ratio is 8:2. Initial presentations of Takayasu's arteritis may be nonspecific like fever, malaise, weakness, fatigue, arthralgia, myalgia and weight loss but in advanced stage there may be features of vascular inflammation like segmental stenosis, occlusion, dilatation and/or aneurysm. It is a sub acute process over months to years and usually with good collateral formation. So, critical limb ischemia due to acute onset of vascular stenosis is very rare. Here we are reporting a case of a 50-year- old male patient who presented with digital gangrene due to critical limb ischemia. Though the age of onset was at 50 years and the patient lacks clinical features like constitutional symptoms, bruit, claudication, asymmetrical blood pressure, the patient was diagnosed as a case of Takayasus's arteritis. The patient dramatically improved with oral glucocorticoid treatment. Although rare, takayasu's arteritis can presents only with digital gangrene without having other clinical features. The physicians should be aware of this unusual but limb threatening presentation and more studies are needed to find out the exact mechanism of this presentation.

Utility of Median-to-Ulnar Sensory Comparative Nerve Conduction Study to Increase Diagnostic Accuracy in Mild Carpal Tunnel Syndrome

Electro-physiological diagnosis of mild Carpal Tunnel Syndrome (CTS) based on traditional median motor and sensory studies are often inconclusive. Therefore, we wanted to investigate the utility of Median-to-Ulnar Sensory Conduction studies in diagnosis of mild CTS. Data from Nerve conduction study (NCS) of 82 cases with symptoms suggestive of CTS from September 2017 to October 2020 attending electrophysiology department of Mount Adora Hospital, Sylhet, Bangladesh was selected for study. About 54(66.0%) out of 82 symptomatic patients were diagnosed as CTS by the conventional method, and 28(34.0%) patients required further investigation as their test report were found to be inconclusive. combining methods showed 70(85.37%) were found to be positive and 12(14.63%) were negative in comparison study. Thus, it can be concluded that those patients found to be negative in conventional methods; comparison method is an option for diagnostic confirmation.

Impact of Levothyroxine on Lipid Profile in Patients with Hypothyroidism

Hypothyroidism is a common endocrine disorder and requires lifelong treatment. Hypothyroidism is often associated with dyslipidemia in some populations. The present study was designed to evaluate the impact of levothyroxine (LT₄) on lipid profile in hypothyroid patients. This cross-sectional analytical study was conducted in the Department of Pharmacology & Therapeutics, Rajshahi Medical College in collaboration with the Institute of Nuclear Medicine and Allied Sciences (INMAS), Rajshahi from July 2018 to June 2019 to compare serum total cholesterol (TC), serum triglyceride (TG), serum LDL-C and serum HDL-C levels among euthyroids, newly diagnosed hypothyroid patients and levothyroxine (LT₄) treated hypothyroid patients. A total of 30 patients with newly diagnosed hypothyroidism and an equal number of age-matched healthy controls (n=30, control group) of both sexes were recruited in the present study. Thirty (30) hypothyroid patients were reevaluated after 6 month of LT₄ therapy. The fasting blood samples were collected from the subjects for the estimation of lipid profile. Significantly higher values were observed in total cholesterol (TC) 198.5±19.2mg/dl, triglycerides (TG) 147.0±14.5mg/dl, low density lipoprotein cholesterol (LDL-C) 133.9±19.7mg/dl (p<0.001) and a significant decreased value was seen in high density lipoprotein-cholesterol (HDL-C) levels (35.1±3.67mg/dl) in newly diagnosed hypothyroid patients as compared to after LT₄ therapy and normal healthy individuals (p=0.009). These observations suggest that people with hypothyroidism have high risk of development of atherosclerosis which may lead to coronary heart diseases (CHD) due to persistent dyslipidemia. Hypothyroidism induces dyslipidemia or expedites the process of existing dyslipidemia, LT₄ therapy corrects it to a significant level thus reduce the risk for atherosclerosis.

Identification of Variants and Mutational Analyses of Cardiac Myosin-binding Protein C (MYBPC3) Gene of Adult Bangladeshi Patients with Hypertrophic Cardiomyopathy

Hypertrophic cardiomyopathy (HCM) is the most prevalent genetic hereditary cardiomyopathy characterized by sudden cardiac death. Mutations in the MYBPC3 gene are often the most prevalent genetic abnormality in HCM with a prevalence ranging from 20.0 to 42.0%. The mutation spectrum is available for different countries, but such studies are lacking in the Asian population including Bangladeshi patients. A cross-sectional descriptive study was conducted for mutation analysis of the whole MYBPC3 gene on a cohort of 75 HCM Bengali Bangladeshi probands through Next Generation Sequencing at the Genetic Research Lab of Bangabandhu Sheikh Mujib Medical University from 2016 to 2019. The structural and functional impact of the mutations was further analyzed by in silico process. We analyzed the data and found 103 variants in 102 locations in the MYBPC3 gene. Variants were identified in both the coding region and the non-coding region. We found one possibly novel variant in the MYBPC3 gene. The findings of this research will help to develop a genetic database of HCM which will help in the early diagnosis and proper management of HCM patients in Bangladesh. One pathogenic splice donor variant (47356592 C >T) was found in the intronic region. Among the variants in the coding region, one missense mutation was pathogenic (NP₋000247.2: p.Asp770Asn) which was found in seven patients and another one is of conflicting interpretations of pathogenicity (NP₋000247.2: p.Ser217Gly) which was found in two patients. We have identified one in-frame deletion (NP₋000247.2: p.Ala433del) that is possible a novel variant responsible for the development of HCM.

Study on Blood Pressure Profile in School Children of Mymensingh City

High blood pressure and its related problems are progressively assuming public health dimensions in developing countries like Bangladesh. There was a suggestion that hypertensive process can be aborted in its early stages. But it is poorly understood in its early stages. So, early natural history of hypertension and its evolution from the youth needs to be investigated. Objective of this study was to determine blood pressure distribution in school children aged 6-15 years. This descriptive cross-sectional study was conducted in the Department of Paediatrics, Mymensingh Medical College, Mymensingh, Bangladesh from November 2014 to October 2015. The sample was collected by simple random sampling from five different schools of Mymensingh after applying inclusion and exclusion criteria. After taking proper history and doing relevant examination, both systolic and diastolic BP was recorded by auscultatory method. Out of 994 children, 480(48.29%) were boys and 514(51.71%) were girls. In boys, the mean±SD of systolic and diastolic blood pressure (BP) were 105.9±10.8 mm of Hg and 67.4±6.7 mm of Hg and in girls it was 106.1±11.8 and 67.5±6.9 mm of Hg respectively. Systolic BP was found higher in girls belongs to 10-13 years. The study has shown that BP rises linearly with age and both systolic and diastolic BP has a significant positive correlation with age, sex, height and BMI in both sexes. This study also showed, 46(4.6%) children were hypertensive and 89(8.9%) were pre-hypertensive. Hypertension was found more in girls but there was no significant difference between two sexes. Hypertension was found more in relation to overweight, obesity and family history of hypertension. Hypertension is not uncommon in children. Routine blood pressure measurement should be conducted in all children.

Repeat breeding: prevalence and potential causes in dairy cows at different milk pocket areas of Bangladesh

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.

A 60-year-old Man Presented with Relapsing Polychondritis with Haemophagocytic Lymphohistiocytosis

Relapsing polychondritis is a rare autoimmune disorder of unknown etiology, which can affect multiple organs. It usually presents with involvement of elastic cartilage of ear and nose and involvement of other organs like kidney and central nervous system. Here, we report a case of 60-year-old man, who initially presented with fever, polyarthritis, erythema nodosum and painful swelling and redness of both external ears admitted in Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, Bangladesh on 13th December 2019. Two days after hospitalization, he developed sudden onset of proptosis with ophthalmoplegia. After evaluation, he was diagnosed as relapsing polychondritis with haemophagocytic lymphohistiocytosis and was treated with high dose prednisolone. His clinical condition and laboratory parameters significantly improved after treating with prednisolone during follow up.

Pattern of Initial Clinical Presentation of Systemic Lupus Erythematosus: A Hospital-Based Cross-Sectional Study from Bangladesh

Systemic lupus erythematosus (SLE) is an autoimmune disorder involving multiple systems and often presents with diverse clinical manifestations. The objective of the present study was to investigate the initial clinical presentations of SLE patients attending a tertiary care hospital in Bangladesh. This cross-sectional study was conducted among 85 SLE patients diagnosed according to the 1997 ACR Revised Criteria for Classification of SLE attending the Lupus Clinic of Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, Bangladesh from January 2012 to June 2013. Sociodemographic and clinical data were collected from patient interviews, physical examinations and medical records. Almost 75.0% of the patients aged below 30 years had a female predominance (male-female ratio 1:5.6). Fever (71.0%), joint pain (60.0%) and alopecia (28.0%) were the most common initial presentations among the patients. Constitutional symptoms such as fatigue, malaise and weakness (23.5%), malar rash (21.0%), oral ulcer (20.0%), photosensitivity (15.0%) and Raynaud's phenomenon (13.0%) were also present in variable proportions. The musculoskeletal and mucocutaneous systems were most commonly affected (85.0% and 75.0% respectively), followed by lupus nephritis (40.0%), hematological symptoms (22.0%) and vasculitis (17.6%). Out of 85 patients, 78 (92.0%) tested positive for anti-nuclear antibodies. SLE patients commonly present with musculoskeletal and nonspecific symptoms at the initial phase. Hence, physicians should consider this clinical and immunological evidence along with conventional symptoms included in the ACR criteria.

Admission Plasma Glucose as In-Hospital Outcome Predictor in First Attack of Non-ST Segment Elevation Myocardial Infarction in Non Diabetic Patient

Coronary artery disease is the leading cause of death and disability globally. The presentation of Non-ST segment elevation myocardial infarction (NSTEMI) is heterogeneous, with different risk levels in terms of death, infarction and recurrence of infarction. Current evidence suggests that plasma glucose level or hyperglycemia is a mediator of worse prognosis of MI. The objective of the study was to correlate on admission plasma glucose level in non-diabetic patient with in-hospital outcome of patients after first attack of NSTEMI. This prospective analytical study was conducted among purposively selected 280 patients with NSTEMI admitted in coronary care unit of Mymensingh Medical College Hospital during the period of June 2016 to May 2017. Data were collected from the informant by face to face interview, clinical examination and investigations using a pretested semi-structured case record form. Data were analyzed by SPSS. Patients were categorized into two groups; Group A: NSTEMI with admission plasma glucose level below 7.8mmol/l, (n=150, Male-110, Female-40). Group B: NSTEMI with admission plasma glucose level ≥7.8mmol/l, (n=130, Male-95, Female-35). Group B (n=130) is divided into two subgroups. Subgroup-I: NSTEMI with Hyperglycemia (7.8-9.3mmol/l), n = 67 (male 44, female 23), Subgroup-II: NSTEMI with Hyperglycemia (≥9.4mmol/l), n = 63 (male 51, female 12). All Patients were non diabetic excluded by HbA₁c. The mean left ventricular ejection fraction (LVEF) of Group B, Subgroup-II was significantly less than that of Subgroup-I (p<0.05). Correlation between LVEF levels and on admission plasma glucose level showed statistically significant moderate negative correlation, suggesting that the higher was the level of on admission plasma glucose level; the lower was the LV ejection fraction level in first attack of NSTEMI patients. Correlation coefficient between Troponin-I and plasma glucose level on admission of the study population (r=0.030) suggesting that the higher was the level of admission plasma glucose level the higher was the Troponin-I level in first attack of NSTEMI patients. The more was the plasma glucose level, less was LVEF, more was the heart failure and prolonged hospital stay. The study showed a strong predictor of adverse in-hospital outcome in the various levels of plasma glucose and NSTEMI. There was association between the concentration of the plasma glucose and the extent, severity of disease in the means of mean LVEF, the rate of heart failure and duration of hospital stay. The importance of this finding is even clear that RBS is a standard, valuable diagnostic tool for evaluation of severity and prediction of outcome of patients with NSTEMI.

Psychological Assessment of Health-Care Workers Working during COVID-19 Pandemic Condition in Bangladesh

The study was aimed to assess the psychological aspects and relevant factors of the health-care workers (HCWs) working in COVID 19 pandemic condition in Bangladesh. This online cross-sectional survey was conducted from different tertiary, secondary and primary hospitals in Bangladesh. Eligible 638 HCWs who were directly involved in the caring of confirmed or suspected COVID-19 patients were recruited in this study. The mental health was assessed by the Patient Health Questionnare-9 (PHQ-9), Generalized Anxiety Disorder-7 (GAD-7) and Athens Insomnia Scale (AIS). High frequency of depression 536(84.0%), anxiety 386(60.5%) and insomnia 302(47.3%) was found among the HCWs, which were significantly higher in physicians (p<0.001) than nurses. Moderate to severe depression was significantly higher in female, whereas minimal to mild depression was significant in male HCWs (p=0.014). Symptoms of depression (p<0.001), anxiety (p<0.001) and insomnia (p=0.004) were significantly higher among the HCWs of primary and secondary compared to the tertiary level. The HCWs developed psychological trauma due to family health (45.3%) and contagious disease property (66.6%). After adjusting confounders, multivariable logistic regression analysis showed that physicians and HCWs of secondary hospital had significant symptoms of severe depression (OR=2.95, 95% CI=0.50-17.24; p<0.001), anxiety (OR=2.64, 95% CI=0.80-8.72; p<0.001) and insomnia (OR=2.67, 95% CI=1.23-5.84; p=0.018); whereas female HCWs had more risk of developing symptoms of severe insomnia (OR= 1.84; 95% CI=1.23-2.75; p=0.003). High rate of depression, anxiety and insomnia was found among HCWs working in the COVID-19 pandemic condition in this survey.

Serum Electrolyte, Serum Calcium and Blood Sugar Status in Severe Acute Malnutrition and Their Relationship with Edema, Vomiting and Diarrhea

Severe acute malnutrition (SAM) is the most severe form of protein energy malnutrition (PEM). Few studies found serum electrolyte, serum calcium level changes as important factors of poor outcome. Hypoglycemia is already established as a risk factor for death in severe acute malnutrition. Edema, diarrhea and vomiting are commonly present in severe acute malnutrition which has impact on electrolyte balance and blood sugar level in healthy children. Their impact in severe acute malnutrition is not clearly established. This cross sectional descriptive study was conducted in Department of Pediatrics, MMCH from March 2018 to October 2019 to estimate serum electrolyte, serum calcium and random blood sugar level in severe acute malnutrition and their relationship with edema, vomiting and diarrhea. Forty-one (41) cases of SAM were enrolled in this study. Test samples were collected before starting the treatment. Case record form was used to collect information. Cases were divided into Group A and Group B based on the presence or absence of vomiting or diarrhea, respectively. Again, all cases were divided into Group C and Group D based on presence or absence of edema, respectively. Data were analyzed using IBM SPSS statistics version 23. Mean age was 9.71±10.4 months with 85.36% having age less than 1 year. Twenty-four (58.5%) were male and 17(41.5%) were female. Parents had low level of education with 48.8% mother and 51.2% father having primary education or no education. Higher number of serum electrolyte, serum calcium and blood sugar were found with hyperglycemia present in 29.3%, hypocalcemia in 22%, hypokalemia in 22% and hyponatremia in 19.5% cases. Hypokalemia was present more in SAM with vomiting or diarrhea (p=0.008). Other disturbances do not vary on presence or absence of edema and vomiting or diarrhea. Result of the present study shows hypokalemia is associated with SAM with vomiting/diarrhea. Hypocalcemia, hyperglycemia, hyponatremia and hypernatremia were also present in high number. These changes should be detected early and treated accordingly.

Proline, a multifaceted signalling molecule in plant responses to abiotic stress: understanding the physiological mechanisms

Abiotic stresses have a detrimental impact on plant growth and productivity and are a major threat to sustainable crop production in rapidly changing environments. Proline, an important amino acid, plays an important role in maintaining the metabolism and growth of plants under abiotic stress conditions. Many insights indicate a positive relationship between proline accumulation and tolerance of plants to various abiotic stresses. Because of its metal chelator properties, it acts as a molecular chaperone, an antioxidative defence molecule that scavenges reactive oxygen species (ROS), as well as having signalling behaviour to activate specific gene functions that are crucial for plant recovery from stresses. It also acts as an osmoprotectant, a potential source to acquire nitrogen as well as carbon, and plays a significant role in the flowering and development of plants. Overproduction of proline in plant cells contributes to maintaining cellular homeostasis, water uptake, osmotic adjustment and redox balance to restore the cell structures and mitigate oxidative damage. Many reports reveal that transgenic plants, particularly those overexpressing genes tailored for proline accumulation, exhibit better adaptation to abiotic stresses. Therefore, this review aims to provide a comprehensive update on proline biosynthesis and accumulation in plants and its putative regulatory roles in mediating plant defence against abiotic stresses. Additionally, the current and future directions in research concerning manipulation of proline to induce gene functions that appear promising in genetics and genomics approaches to improve plant adaptive responses under changing climate conditions are also highlighted.

TB prevalence among patients with diabetes in Bangladesh

OBJECTIVE: 1) To assess the prevalence of TB among patients with diabetes mellitus (DM) attending diabetic care centres in Bangladesh, and 2) to compare TB- and DM-related sociodemographic and other factors in diabetic patients who had TB and those who did not.METHODS: This cross-sectional study was conducted from 1 June 2019 to 31 March 2020 in 108 centres of the Diabetic Association of Bangladesh (BADAS), with a sample size of 3,649 patients with DM. Data were collected by face-to-face interview using semi-structured questionnaire from each patient/guardian. Other ethical issues were also maintained.RESULTS: Out of 3,649 patients with DM, 676 presumptive TB cases were identified and tested; from them, 85 patients were detected as TB cases. Another 39 patients were already diagnosed and on anti-TB medication. Prevalence of TB among patients with DM attending diabetic care centres was 3.4%. Prevalence was higher in female than male (4.0% vs 2.6%). Underweight (9.0%) patients and patients having diabetes for more than 10 years (7.1%) had a higher prevalence of TB.CONCLUSION: TB prevalence was over 3% among study population with DM. Periodic screening and active case finding among DM patients should be strengthened to reduce the risk of TB infection among DM patients.

Change of Hemoglobin Level among Exclusively Breastfed Term and Preterm Babies up to Six Months of Age

There is progressive increase of Hb levels is observed during course of intrauterine development of fetus but high concentrations found at birth. In preterm neonate normal Hb is characteristically deviated from term neonate. Breast milk is the only natural ideal food for both term and preterm babies from birth up to 6 months. Preterm milk was found to contain significantly higher concentrations nutrients particularly iron than term milk. Preterm human milk is more suitable for the premature infant than term human milk. As Hb concentration varies in term and preterm babies in different counties in different feeding practices. The purpose of this longitudinal descriptive study is to find out the pattern of changes in the Hb level among exclusively breastfed preterm and term infants during the first six months of life. This study was carried in the Neonatal Intensive Care Unit (NICU), Mymensingh Medical College Hospital (MMCH), Mymensingh from September 2016 to February 2018. One hundred fifty (150) neonates both term and preterm were included in this study and followed up to 6 months of age. After admission informed written consent was taken from parents, thorough history taking and clinical examination were done. Data were collected in a pre-designed case record form. All the babies of Group A provided 2mg/kg iron supplementation from 6 weeks for 2 months for universal recommendation. Hb level was measured of all exclusively breast feed babies at admission after birth then next follow-up at 6 weeks, 3 months and 6 months. All information regarding history, anthropometrics measurement, Hb level was recorded in structural questionnaire. Data analysis was done by SPSS version 20.0. Male were predominant in both groups. Most of the preterm (72.0%) and term babies (65.3%) were delivered by vaginal route. Mean Hb level was found significantly higher among preterm babies than term babies after birth were 16.55g/dl and 15.98g/dl respectively. Sharp fall of Hb concentration was observed after birth up to 6 weeks in both preterm and term babies but Hb level was found significantly lower in preterm in comparison to term babies (9.27gm/dl vs. 9.58gm/dl). In term babies, even after 6 weeks fall of Hb level continued to 3 months of age followed by gradual increase up to 6 months without iron supplementation. Hb level of in preterm babies gradually increased from 6 weeks up to 6 months with universal iron supplementation. Hb level fall sharply up to 6 weeks in both exclusively breastfed term and preterm babies but even after 6 weeks term babies experienced gradual fall of Hb levels up to 3 months. Hb level increases in exclusively breast-fed term babies without iron supplementation from 3 months of age. Hb level in exclusively breastfed preterm babies increase from 6 weeks onward might be effect of universal iron supplementation.

A Middle-Aged Woman Presented with Catastrophic Anti-phospholipid Syndrome in Nephrology Department of BSMMU

A life threatening rare condition called catastrophic antiphospholipid syndrome leading to multiple organ failure is characterized by vascular thrombosis in the presence of anti-phospholipid antibody which often appear as a medical emergency. Antiphospholipid antibody syndrome whether primary or secondary cause thromboembolic manifestation resulting recurrent fetal loss, but catastrophic antiphospholipid antibody syndrome may not present in such a way, rather multi-system involvement occurs within a short period of time. We would like to present a case of 50 years old female who is hypertensive, non-diabetic, a known case of hypothyroidism for two years, who was admitted to our hospital after developing fever for 7 days and black discoloration of lateral three fingers of left hand for short period of time. The patient had no medical problems and had been in her usual state of health until 7 days before admission. Patient is anaemic and found to have severe renal failure. She was found high titer antiphospholipid antibody both IgM and IgG positive and anti-cardiolipin antibody positive. Her routine investigations revealed very high neutrophilic leukocytosis, high acute phase reactant, urinary findings revealed no active sediment; we thought that our patient might have sepsis that may trigger catastrophic antiphospholipid syndrome. Multi-disciplinary consultation gave us valuable opinion. Considering her septicemia, she was given broad spectrum antibiotic. Anticoagulation was given with unfractionated heparin followed by warfarin and as an immunosuppressive protocol methylprednisolone followed by prednisolone along with pulse cyclophosphamide was given. Treatment option with plasma pheresis and monoclonal antibody was not attempted, but she was given several session of hemodialysis, within a few days her biochemical parameters improved. Severe renal failure in this patient may be explained by septicemia or thrombotic micro-angiopathy that was reversed with anti-coagulation or proper antibiotic. Amputation of three digit of left hand was done by orthopedic surgeon but unfortunately two weeks after admission the patient expired due to sudden stroke.

The effect of metal substitution in CsSnI3 perovskites with enhanced optoelectronic and photovoltaic properties

Non-toxic lead-free halide metal perovskites have gained significant interest in photovoltaic and optoelectronic device applications. In this manuscript, we have studied the structural, electronic, mechanical, and optical properties of eco-friendly cubic CsSn_1-x Cu _x I₃, (x = 0, 0.125, 0.25, 0.5, 1) perovskites applying first-principles pseudopotential-based density functional theory (DFT). Cu-doped CsSnI₃ has a large impact on the band gap energy viz. the transition of direct band gap towards the indirect band gap. The mechanical properties demonstrate that the pristine and Cu-doped CsSnI₃ samples are mechanically stable and their ductility is enhanced by Cu doping. The mechanical stability and ductility favors the suitability of pure and Cu-doped samples in the thin film industry. The absorption edge of Cu-doped CsSnI₃ moves towards the lower energy region in comparison with their pure form. In addition, the high dielectric constant, high optical absorption, and high optical conductivity of Cu-doped CsSnI₃ materials suggests that the studied materials have a broad range of applications in optoelectronic devices, especially solar cells. A combined analysis of the structural, electronic, mechanical and optical properties suggests that CsSn_1-x Cu _x I₃, (x = 0, 0.125, 0.25, 0.5, 1) samples are a suitable candidate for photovoltaic as well as optoelectronic device applications.

A Comparative Study between Magnetic Resonance Imaging and Clinical FIGO Criteria in Different Stages of Carcinoma Cervix

The objective of this study was to determine whether Magnetic Resonance Imaging is a sensitive and specific alternative method to clinical FIGO criteria in the staging of cervical carcinoma. This prospective cross-sectional study was conducted in the Department of Radiology and Imaging, BSMMU, Dhaka during the period of September 2018 to August 2020. A total of 60 patients were selected purposively and all are staged clinically by EUA. Then all samples underwent MRI in Department of Radiology and Imaging, BSMMU. Images of uterine cervix, corpus, vagina and parametrium were taken with a prefixed standard protocol (TIWI axial, T2WI axial and sagittal, DWI axial & DCE) and reporting was done by Radiologist. Comparison was done between the MRI and clinical FIGO criteria of staging of cervical carcinoma. P value <0.05 was considered as significant. Sensitivity & specificity of the MRI was measured. Data were analyzed by using Statistical Package for Social Sciences (SPSS) software version 23.0 for Windows (SPSS Inc., Chicago, Illinois, USA). Out of 60 patients in this study the mean age was found 47.5±10.1 years with range from 22 to 60 years. Positive correlation (r=0.993; p=0.001) between histopathological size and MRI size of tumour. Positive correlation (r=0.950; p=0.001) between histopathological size and FIGO size of tumour. MRI findings more correlates with histopathology than clinically detected tumor size. The sensitivity, specificity, accuracy, positive and negative predictive values of MRI diagnosis evaluation for vaginal extension was 100.00%, 95.20%, 100.00%, 98.30% and 97.50% respectively. Sensitivity, specificity, accuracy, positive and negative predictive values of MRI diagnosis evaluation for parametrial invasion was 100.00%, all. In this study we observed that MRI staging was more likely to be concordant with pathological stage in comparison to the clinical stage. There was a concordance rate of 95.00% in MRI and 65.00% in clinical staging respectively. Out of 3 non-concordant cases in MRI, 2 were upstaged and 1 case was down staged in histopathology. FIGO staging concurred with histopathology in 39(65.00%) cases and differed in 21(35.00%) cases. Magnetic resonance imaging (MRI) is a sensitive and specific modality for accurate staging of cervical carcinoma in comparison with clinical FIGO criteria considering histopathology as gold standard.

Comparison of Nutritional Status of Children with Congenital Heart Diseases with Minor Illness of Other Children in a Tertiary Level Hospital

This cross sectional comparative analytical study was undertaken with the objectives to find out the nutritional status of children with congenital heart disease by anthropometric measurement and was compared it with those of children having minor illness and without any congenital heart disease in indoor and outdoor Department of Paediatrics of Mymensingh Medical College Hospital (MMCH), Mymensingh, Bangladesh from December 2015 to November 2016. Purposive sampling was done. One hundred children aged 6 to 60 months with congenital heart disease confirmed by echocardiogram were taken as Group A and one hundred children of same age and sex matched having minor illness and without any congenital heart disease were taken as Group B. Age of the patients ranged from 6 to 60 months. There was no obvious difference of socio-demographic status between two groups. Most of the patient (64.0%) had acyanotic congenital heart disease among them VSD was commonest (68.8%). Thirty-six percent (36.0%) patient had cyanotic congenital heart disease and among them Tetralogy of Fallots (83.3%) was commonest. There were significant differences regarding weight, height and MUAC values in between two Groups. Underweight (51%), Stunting (50%) and Wasting (29%) all were higher in congenital heart disease than that of Group B where they were 28%, 31% and 13% respectively and the differences were statistically significant (p<0.05). The findings of this study imply that malnutrition is very common among children with congenital heart disease. So, anthropometric measurement should be done in each and every child with congenital heart disease.

Overweight and Obesity among Children of Primary Schools of Mymensingh Municipal Area

Obesity is now recognized as a major cause of morbidity and mortality throughout the world. The relative percentage of change is higher in developing countries. Childhood obesity has become a serious public health emerging problem because of its strong association with adulthood obesity and related adverse health consequences. The main objective of the study was to find out the status of overweight and obesity among primary school children of Mymensingh municipal area. This cross sectional descriptive study was carried out among primary school children of Mymensingh municipal area from September 2016 to February 2018. Total 1450 students were enrolled from 6 schools. Schools were selected by random lottery method. Data was collected in predesigned case record forms by investigator with the help of students, teachers and parents. Anthropometry was measured by principal investigator. Body mass index (BMI) was calculated and plotted by using Center for disease control (CDC) BMI growth charts for age and sex. Children were categorized as obese, overweight, normal and underweight. Data analysis was done by computer software SPSS version 20.0. Mean age of children was 9.0±1.124 years. There was 47.4% male and 52.6% female. Among the 1450 children 18.6% obese, 17.5% overweight, 53.5% normal and 10.4% underweight. So, total 36.1% children had BMI above normal limit. Obesity was found more common among male children (p<0.001). Obesity and overweight was significantly associated with fast food consumption (p<0.001), playing computer and mobile games (p<0.001), watching TV (p<0.001), higher parent's education (p<0.001), higher parent's income (p<0.001), service holder father (p<0.001), family history of overweight or obesity (p<0.001), single child in family (p<0.001) and increased birth weight (p<0.001). A large number of primary school children in Mymensingh municipal area were overweight and obese. Childhood obesity and overweight varies from school to school. Childhood obesity and overweight is an emerging and growing health issue in municipal area.

Outcome of Danis-Weber Type-B ankle fracture treated by Pre-contoured Distal Fibular Locking Plate

Danis-Weber type-B ankle fracture is one of the most common injuries in young and active individual. This fracture offers a considerable challenge to orthopedic surgeon. Though there are several options for treating such type of fracture, ORIF by Pre-contoured Distal Fibular Locking Plate is the preferred option in the recent years. This descriptive type of observational study was performed from July 2017 to June 2019 in NITOR. Thirty (30) patients, 22 male and 8 female with an average age of 39 years with Danis-Weber type-B ankle fracture underwent ORIF by Pre-contoured Distal Fibular Locking Plate for fractured fibula and ORIF by 4.0mm cannulated cancellous screw for fractured medial malleolus. All the patients were initially managed by analgesic and short leg posterior slab. Average follow up was 24 weeks. Final outcome was assessed by AOFAS score. The main cause of injury was RTA (56.67%). Mean operation time was 1.2 hours. Mean duration of Hospital stay was 16.43±1.73 days. Superficial infection was in 3.33% and skin necrosis in 3.33% patient. Mean duration of radiological healing was 12.73±0.39 weeks. At final follow up, mean dorsi flexion was 10.93°±0.357° and plantar flexion was 50.93°±0.357°. Ninety percent (90%) patient had no difficulties in walking on any surface; 96.67% patient had stable ankle hind foot; 86.67% patient had good. Ten percent (10%) had fair and 3.33% patient had poor alignment of foot. The mean score in this study was 88.67±2.31. Satisfactory outcome was observed in 86.67% patients and 13.33% had unsatisfactory results. On the basis of results in the present study, it can be concluded that treatment of Danis-Weber type-B ankle fracture by Pre-contoured Distal Fibular Locking Plate is an effective and reliable method.

Risk Factors of Neonatal Sepsis in Neonatal Intensive Care Unit (NICU) of Mymensingh Medical College Hospital

Neonatal sepsis is associated with increased mortality and morbidity including prolonged hospital stay. Management of such cases is difficult, costly and need expert centers in many cases. Therefore, continued surveillance is mandatory to identify risk factors of neonatal sepsis which help optimizing its management. With the above idea, this cross-sectional descriptive study was conducted at the neonatal intensive care unit (NICU) in the department of Neonatology, Mymensingh Medical College Hospital (MMCH), Mymensingh, Bangladesh from July 2017 to December 2017 to observe the effects of maternal and neonatal risk factors in the development of neonatal sepsis and to determine risk factors of neonatal sepsis. Ninety four neonates (0-28 days) who were admitted in NICU with suspected sepsis were included in this study by purposive sampling technique. After admission written informed consent from parents or guardians obtained and histories were obtained including perinatal history and full physical examination of the infants were done and septic screening were sent. All the relevant information was recorded in a pre-designed questionnaire and all data were compiled, tabulated and then analyzed by SPSS version 21.0. Among 94 cases, 72.3% were preterm and 27.6% were term. There was male predominance and male/ female ratio was 1.9:1. Most (76.6%) of the patient admitted within 72 hours of birth. Most (83%) had low birth weight (<2500gm). Most came from rural area 61(64.9%) and also from low income family 59(62.8%). Premature onset of labour 40(42.6%), PROM >18 hours 36(38.3%), vaginal route of delivery 52(55.3%), instrumental resuscitation 15(16%), prelacteal feeding 11(11.7%), bottle feeding 15(16%) were the antenatal, natal and postnatal risk factors in this study. Also the neonatal factors, like prematurity, resuscitation at birth and low APGAR score carried the significant risk of developing sepsis. Poor feeding, lethargy, respiratory distress, jaundice were more common presenting symptoms. Tachycardia, tachypnea, chest indrawing, cyanosis hypothermia, hyperthermia and apnoea were found as more common presenting sign of sepsis in this study. Based on result it is concluded that prolonged rupture of membrane>18 hours, vaginal route of delivery, preterm birth, instrumental resuscitation, prelacteal feeding, bottle feeding were the major perinatal risk factors in this study.

Risk Factors of UTI in Children with Nephrotic Syndrome

Urinary tract infection (UTI) is a common complication in nephrotic children and leads to most morbidity and mortality in developing countries like Bangladesh. This case control study was conducted in the Department of Pediatrics and Pediatric Nephrology ward of Dhaka Medical College Hospital, Dhaka from July 2016 to June 2018 to identify the risk factors of UTI in children with nephrotic syndrome. Total 90 patient of nephrotic children aged 2-12 years, who were fulfilling the inclusion and exclusion criteria were selected as Group I (case) and Group II (control) according to urine culture report. Group I was UTI positive and Group II was UTI negative. The mean age of Group I was 5.26±3.18 years and Group II was 6.03±2.85 years. There was male predominance in both groups. No significant difference has been found regarding age and sex (p>0.05). No significant difference was also observed regarding economic status and educational level of mother among both groups (p>0.05). Fever, dysuria, abdominal pain, anasarca, vomiting and pallor were found as common presentations in Group I. Children with dysuria and abdominal pain were significantly higher in Group I than Group II (p value <0.001). UTI was found more in relapsed cases than initial attack. E. coli was the most common etiologic agent (37.8%). Mean Hb (gm/dl), serum total protein, serum albumin and serum IgG level were found significantly lower and spot urine protein creatinine ratio was significantly higher in Group I, which implies that those biochemical factors were associated with development of UTI in nephrotic children. Younger age group (<6 years), Constipation and uncircumcised male were found as risk factors and has association with UTI in nephrotic children.

MO111PATTERN OF CARDIAC AND RENAL RISK FACTORS PREVAILING IN HYPERTENSIVE SUBJECTS OF RURAL COMMUNITY: PRIMARY RESULTS FROM AN ONGOING SYSTEMATIC SURVEY IN BANGLADESH

Background and Aims

Hypertension is the leading entity of non communicable diseases (NCD). Some 15-30% adult population is identified suffering from hypertension at any given time worldwide. Complications of hypertension cause severe functional deficit and a major decline in quality of life for the patient and family.

This study was carried out to identify the presence and pattern of cardiac and renal risk factors influencing major morbidity and mortality in hypertensive subject by performing relevant clinical and laboratory evaluations.

Method

In this survey adult subjects were selected randomly from a defined rural area. Their demographic, anthropometric and clinical information was recorded by WHO STEP wise approach surveillance-Instrument v.3.1. Information on prevailing NCDs and related risk factor were collected on a short questionnaire by face-to-face interview. Blood Pressure (BP) was measured by digital blood pressure monitor (Omron) with standard sized cuff after 10-15 minutes of rest in sitting posture by taking mean of two readings. Systolic BP ≥140 and/or diastolic BP ≥90mmHg or subjects taking antihypertensive medications were considered for hypertension. Early morning urine and fasting blood sample was collected for glycemic profile, lipid profile, serum creatinine, eGFR (MDRD equation) and urine ACR estimations for identifying diabetes, dyslipidemia and nephropathy. Results from an early group are presented here.

Results

From surveyed population consequative 300 hypertensive subjects with 100 normotensive subjects were analyzed. Male/female distribution was 66% and 34%. Age in 75% was between 25-55 years and BMI overweight to obese in 45%. Etiology wise in 81% it was essential hypertension followed by diabetes 18% and nephropathies in rest. Mean systolic BP was 147±16 and diastolic BP 71±9 mmHg. Comparison of hypertensive vs. normotensives showed FBS 6.7±3 vs. 5.8±1.0 mmol/l, (p&lt;0.001). Lipids as cardiac markers were TG 170±107 vs. 130±76 g/dl, (p&lt;0.001); Cholesterol 195±50 vs. 180±49 g/dl, (p&lt;0.001); LDL 170±107 vs. 130±76 g/dl, (p&lt;0.04); and HDL 42±7 vs. 46±8 g/dl, (p&lt;0.001). Renal parameters like eGFR was 88±22 vs. 98±26 ml/min, (p&lt;0.001); and ACR 99±556 vs. 30±87 mg/g, (p&lt;0.04). These comparisons showed fasting hyperglycemia with most of the lipids higher and HDL lower in hypertensives. Renal parameters like eGFR was lower and albuminuria was significantly higher with similar urinary Na and K excretion in hypertensives. Other cardio renal markers like Uric Acid and hCRP was similar in both groups. Pearson’s correlations showed a positive correlation of systolic and diastolic BP with major components of cardiac, renal and metabolic risk factors.

Conclusion

It is found that hypertension is essential in nature among 81% of rural subjects. Nearly half of the study subjects are overweight. Dyslipidemia, albuminuria and low GFR is more pronounced in hypertensives in comparison to the normotensive counterparts. So, hypertension is mostly associated with adverse cardio-renal risk markers.

On the association between circulating biomarkers and atherosclerotic calcification in a cohort of arterial disease participants

BACKGROUND AND AIMS

Atherosclerotic calcification is a powerful predictor of cardiovascular disease. This study aims to determine whether circulating levels of a local/systemic calcification inhibitor or a marker of bone formation correlate with measures of coronary or extracoronary calcification.

METHODS AND RESULTS

Clinical computed tomography (CT) was performed on 64 arterial disease participants undergoing carotid and lower extremity endarterectomy. Coronary artery calcium (CAC) scores and volumes were acquired from the CT scans (n = 42). CAC scores and volumes were used to derive CAC density scores. Micro-CT was performed on excised carotid (n = 36) and lower extremity (n = 31) plaques to quantify the volume and volume fraction of extracoronary calcification. Circulating levels of dephospho-uncarboxylated Matrix Gla Protein (dp-ucMGP), fetuin-A, carboxylated and uncarboxylated osteocalcin (ucOC) were quantified using commercial immunoassays. Carotid participant CAC density scores were moderately negatively correlated with plasma dp-ucMGP (rs = -0.592, P = 0.008). A weak negative association was found between CAC scores and %ucOC for all participants (rs = -0.335, P = 0.040). Another weak negative correlation was observed between fetuin-A and the volume of calcification within excised carotid specimens (rs = -0.366, P = 0.031). Despite substantial differences in coronary and extracoronary calcium measurements, the levels of circulating biomarkers did not vary significantly between carotid and lower extremity subgroups.

CONCLUSION

Correlations identified between circulating biomarkers and measures of coronary and extracoronary calcium were not consistent among participant subgroups. Further research is required to determine the association between circulating biomarkers, coronary and extracoronary calcium.
