RESUMO
Multiple myeloma (MM), mature B-cell lineage neoplasm, is characterized by abnormal clonal proliferation of plasma cells and presence of monoclonal protein (M protein). The study was conducted to reveal presenting features, laboratory findings, Eastern Cooperative Oncology Group (ECOG) performance status and skeletal survey on patients with multiple myeloma. This descriptive, cross-sectional study was carried out in the Department of Haematology, Dhaka Medical College Hospital, Dhaka, Bangladesh from January 2019 to July 2020 with a sample size of 81. Data were collected in a case record form after obtaining informed verbal consent from patients and /or their legal guardians. Relevant ethical issues and data quality assurance were taken into consideration. Data were analyzed with SPSS, Version 25.0 with presentation in figures and tables with frequency, percentage, mean and standard deviation based on data nature. Statistical tests were carried out as appropriate with 5.0% level of significance for assessing statistical association. Mean age of the patients was 58.9±12.0 years. Male female ratio was 2:1. 35(43.2%) patients were smokers with only 2(2.5%) had family history of haematological malignancies. Bone pain (72.8%) was the most common presenting feature, while hypertension (59.1%), diabetes mellitus (29.5%), respiratory illness (11.3%) and cardiac disease (11.4%) were the common co-morbidities. Most common ECOG performance status was ECOG-1(48.1%). Mean haemoglobin (Hb) was 9.4±2.3gm/dl and mean erythrocyte sedimentation rate (ESR) was 89.5±42.1 mm in 1st hour. Mean serum creatinine level was 2.0±1.85 mg/dl and ≥2.0mg/dl in 42(34.2%). Among 50 documentation serum lactate dehydrogenase (LDH) was raised in 18(36.0%). Mean serum calcium level was 9.6±1.8mg/dl >11.0mg/dL in 10(14.5%) cases. Serum albumin <3.5gm/dl in 37(49.3%), ß2-microglobulin >5.5mg/dl in 37(57.8%) cases, International staging system (ISS) stage III was in 59.4% and Bence Jones Protein (BJP) was present in 46.7% cases. Lytic lesions were present in 75.0%, In 38(74.5%) patients vertebrae were involved, while in 18(35.2%) ribs were involved, in 14(27.5%) patients skull was involved and in 3(5.9%) patients involved bones were femur, humerus, sternum and scapula. Mean plasma cells percentage was 62.1±24.9%. Immuno-Fixation Electrophoresis (IFE) revealed IgG (72.7%), IgA (18.2%), Free light chain (FLC) (9.1%). FLC ratio was ≥100 in 29.0% cases. Significant statistical association was observed between serum creatinine with Hb concentration (p<0.05), serum creatinine level with ISS staging (p<0.05) and serum calcium level (p<0/05), while insignificant association was revealed between BJP present status and serum creatinine level (p>0.05). Bone pain, fatigue, fever and neurological impairment were the common presenting features. Anaemia, renal impairment and skeletal lytic events were the prominent physical findings. ISS staging was statistically associated with serum creatinine level, while serum calcium level was associated with serum creatinine and lytic lesions.

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.

The C3-symmetry ionic polymer PPyTri has been designed with multi-walled carbon nanotubes (MWCNTs) or graphene nanoplatelets (GNPs) and studied as an ultrasensitive electrochemical sensor for trace Hg(II) detection. The synthesis approach incorporated attaching three pyridinium cationic components with chloride anions to the triazine core. The precursors, BPy, were synthesized using a condensation process involving 4-pyridine carboxaldehyde and focused nicotinic hydrazide. The polymer PPyTri was further modified with either MWCNTs or GNPs. The resulting ionic polymer PPyTri and its fabricated nanocomposites were characterized using infrared (IR), nuclear magnetic resonance (NMR), scanning electron microscopy (SEM), transmission electron microscopy (TEM), and powder X-ray diffraction (XRD). The analysis revealed that both the polymer and its nanocomposites have semi-crystalline structures. The electroactivity of the designed nanocomposites toward Hg + 2 ions revealed that among the nanocomposites and bare copolymer, the glassy carbon electrode (GCE) adapted with the PPyTri GNPs-5% exhibited the greatest current response over a wide range of Hg + 2 concentrations. The nanocomposite-modified electrode presented an excellent sensitivity of 83.33 µAµM - 1 cm - 2, a low detection limit of 0.033 nM, and a linear dynamic range of 0.1 nM to 0.01 mM (R2 = 0.9945).
RESUMO
A poly(luminol-o-anisidine-o-toluidine) terpolymer was synthesized, characterized, and modified with GNPs and ZnO NPs. The nanocomposites were then examined for their electroactivity and potential use as cationic electrochemical sensors for detecting Sb3+ ions in phosphate buffer on the surface of a glassy carbon electrode (GCE). Among the different compositions and the terpolymer, the GCE adapted with the PLAT/ZnO/GNPs-5% nanocomposite displayed the highest current response. The fabricated nanocomposite sensor exhibited high sensitivity, with a value of 21.4177 µA µM-1 cm-2, and a low detection limit of 95.42 pM. The analytical performance of the sensor was evaluated over the linear dynamic range (LDR) of 0.1 nM to 0.01 mM. The proposed sensor is effective in detecting and measuring carcinogenic Sb3+ ions in real environmental samples using an electrochemical approach, making it a promising tool for environmental monitoring.
RESUMO
Urothelial carcinoma (UC) is the most common malignancy of urinary bladder. It is the 9th leading cause of death worldwide and second most common genitourinary malignancy among male. Incidence is increasing in developing countries like Bangladesh. About 80% of patients are found between 50 to 80 years of age. It is 3-4 times more common in male than in female. Determination of therapeutic strategy and prediction of progression of urothelial carcinoma is a major clinical challenge. Treatment of urothelial carcinoma still now mostly depends on pathological stages. Amplification or genomic alteration of Cyclin D1 (a proto-oncogene) may cause protein overexpression which is frequently realized as a clonal pathology in various human neoplasms including bladder cancer. Evaluation of Cyclin D1 expression is promising for guiding therapeutic strategies, risk stratification and prediction of tumor progression. The aim of the study was to determine the expression of Cyclin D1 in urothelial carcinoma of urinary bladder and its association with tumour grade. This cross-sectional observational study was conducted in Department of Pathology, Dhaka Medical College, Dhaka, Bangladesh from July 2019 to June 2021. Histomorphologically diagnosed 51 urothelial carcinomas were included. Sections were stained with hematoxylin and eosin. Immunostaining with Cyclin D1 antibody was also done. Relevant information was collected and recorded in a predesigned data sheet. Statistical analysis was carried out as required. Mean age ±SD was 57.8±10.55 years. Male female ratio was 4.6:1. In this study 39(76.5%) patients were smoker. Regarding clinical presentations 36(70.6%) patients presented with painless hematuria alone. Lateral wall (64.7%) was the most frequent tumor location. Among 51 cases, 38(74.5%) cases were high grade urothelial carcinoma (HGUC) and 13(25.5%) cases were low grade urothelial carcinoma (LGUC). Considering Cyclin D1 expression, most of the LGUC cases showed high level of expression by both percentage (84.6%) and intensity (84.6%). Most of the HGUC cases showed low level of expression by both percentage (63.2%) and intensity (60.5%). Cyclin D1 showed significant inverse association with HGUC (p<0.05). In urothelial carcinoma of urinary bladder, Cyclin D1 expression was decreased with increasing grade of the tumor. Cyclin D1 expression was inversely associated with tumour grade.

Pesticides including cypermethrin (10% EC) are commonly used pesticide in tea gardens of Bangladesh possess distinct harmful effects on an aquatic community. The experiment was carried out to assess the ecotoxicological effects of cypermethrin (10%) concentrate on indigenous Climbing Perch (Anabas testudineus). A total of 120 A. testudineus (mean length 16 ± 2.67 cm and mean weight 31.6 ± 3.56 g) were exposed to the acute toxicity test when the lethal concentration 50 value (LC50) for 96 h was maintained at 1.00 ppm. Three different sub-lethal concentrations of 0.05 ppm (5%), 0.10 ppm (10%), and 0.20 ppm (20%) were used respectively as three treatments and a control of 0 ppm with three replicates each. Restlessness, erratic movement, increased opercular activities, loss of equilibrium, and irregular response to feeding were observed in all the treatments compared to control one. Concerning histopathological alterations, all the analyzed organs showed highest changes in the T3 (cypermethrin conc. 20%) compared to other treatments while T0 (0 ppm) had normal structure. The major changes in the gill were epithelial cell hyperplasia, necrosis, severe lamellar fusion and epithelial lifting; while necrotic proximal tubules, glomerular shrinkage, disrupted renal corpuscle of the kidney and nuclear pyknosis, degenerated hepatic cells and vacuolation were observed in the liver. Severe melanomacrophage centre (MMC), haemosiderosis and vacuolation were found in spleen. The effect of cypermethrin on the hematological parameters of experimental fish was also studied. Red blood cells, hemoglobin and hematocrit were decreased in the experimental groups and lowest value was in T3 while values of white blood cells were increased in the experimental groups compared to control one. Hence, the present observation revealed that pesticides even at low concentrations can cause harmful effects on A. testudineus.
RESUMO
In this study, poly(luminol-co-1,8-diaminonaphthalene) (PLim-DAN) was synthesized and subsequently modified with MWCNTs and CeO2 NPs. The synthesized nanocomposites were analyzed using IR, SEM, TEM, and XRD. Furthermore, a comprehensive set of thermal behavior measurements were taken using TGA/DTG analysis. Next, the electroactivity of the developed nanocomposites was tested as an electrochemical sensor to measure the concentration of Cr3+ ions in phosphate buffers. The GCE adapted with the PLim-DAN/CeO2/CNTs-10% nanocomposite (NC) exhibited the highest current response among the other compositions and copolymers. The fabricated nanocomposite sensor showed high sensitivity, with a value of 19.78 µA µM-1 cm-2, and a low detection limit of 4.80 ± 0.24 pM. The analytical performance was evaluated by plotting a current calibration curve versus the concentration of Cr3+ ions. It was found to be linear (R2 = 0.9908) over the range of 0.1 nM to 0.1 mM, identified as the linear dynamic range (LDR). This electrochemical sensor demonstrated that it could be a useful tool for environmental monitoring by accurately detecting and measuring carcinogenic Cr3+ ions in real-world samples.
RESUMO
The aim of the study was to evaluate the quantities difference and persistence of antibody in home and hospital treated patients at different interval. A cross-sectional study was conducted in the Department of Biochemistry and Molecular Biology, BIRDEM General Hospital, from July, 2020 to June, 2021. This study protocol was approved by Institutional Review Board (IRB), BIRDEM. SARS-CoV-2 caused death of huge number of people. The disease most commonly represents with fever, cough, loss of smell sensation, fatigue etc. Who had mild symptoms did not admit at hospital. But when the disease progress to respiratory distress, involvement of lung field more than 50.0% and other complications then the patients need hospital admission. Hospital treated patients showed higher antibody status in comparison to home treated patients. Moreover it was reported that increased amount of antibody developed after 3rd and 4th months of SARS-CoV-2 infection. In this study, statistically significant difference of decaying antibody level between home and hospital treated patients was observed.

Background: Paraquat poisoning is one of the leading causes of fatal poisoning in many parts of the world, especially in agricultural countries. Its high toxicity even in small amounts causes rapid damage to multiple organs, especially the kidneys, lungs, and liver, mainly through free radical-mediated injury. As no specific antidote is yet available, early diagnosis and the importance of supportive therapy are critical parts of management. Some evidence suggests a survival benefit from using immunosuppressive drugs. Case report: This case presentation concerns a 15-year-old boy from a village with a history of herbicide poisoning, later confirmed to be paraquat. Despite supportive therapy her condition continued to deteriorate with features of kidney and lung damage. The patient was then treated with methylprednisolone 500 mg daily for 5 days, along with other supportive care, and has made a remarkable recovery. Conclusions: High efficacy as an herbicide, availability and low cost make paraquat an easy-to-encounter poison for suicidal or accidental use. Its high fatality calls for urgent and effective strategies to save lives. Methylprednisolone may play a role in its treatment.
RESUMO
Vulvovaginal Candidiasis (VVC), a frequent and cumbersome reproductive tract infection affects women's physical and mental health. Although Candida albicans was reported as the most common agent of VVC yet, recently there are significant changes in the pattern of Candida species causing VVC with varying antifungal susceptibility pattern. Therefore this cross-sectional, descriptive type of observational study conducted to identify the spectrum of Candida species associated with VVC and assesses their antifungal susceptibility pattern from March 2021 to February 2022. High vaginal swabs from 175 patients clinically suspected of VVC were collected and cultured on Sabouraud dextrose agar with Chloramphenicol. Species were identified by phenotypic methods like- germ tube test, sub-culture in chromogenic agar media and genotypic methods like- Polymerase chain reaction (PCR), Restriction fragment length polymorphism (RFLP). Antifungal susceptibility was done by disk diffusion method. Out of 175 patients, 52(29.7%) were positive for Candida species. Of the isolates- C. albicans 34(65.0%), Non albicans Candida (NAC) 18(35.0%). Among NAC, C. glabrata 5(9.6%), C. tropicalis 5(9.6%), C. parapsilosis 4(7.7%) and each of C. krusei, C. kefyr, C. ciferrii, C. dubliniensis were 1(1.9%). On susceptibility testing highest resistance was to Clotrimazole 31.0% followed by Nystatin 13.0%, Itraconazole 12.0% and Fluconazole 10.0%. Resistance to azole was higher in NAC than in albicans. Of these patients, 16(31.0%) had history of recurrent VVC (RVVC) of which 12(75.0%) were by NAC, predominantly C. glabrata 5(32.0%). The results showed the increasing incidence of NAC associated vaginitis with higher resistance and recurrence that should be considered in gynecology clinics.

Otomycosis, a fungal infection of external ear, is challenging for both patients and otolaryngologist as it requires long term treatment and follow up. Candida spp. is second common organism causing otomycosis with Aspergillus being first. Among Candida species, C. albicans is considered as most common but in recent years there is increasing incidence of Non albicans Candida (NAC) species with greater resistance and recurrence. This descriptive type of observational study was planned to determine the species distribution and antifungal susceptibility of Candida spp. causing otomycosis. From March 2021 to February 2022, 60 patients clinically suspected of Candida associated otomycosis at Mymensingh Medical College Hospital, Bangladesh were enrolled. Specimens were taken by an otorhinolaryngologist. After culture and microscopic examination, isolated Candida species were identified by phenotypic and genotypic method and antifungal susceptibility was determined at Department of Microbiology, Mymensingh Medical College. From 60 samples 18(30.0%) were positive for Candida on microscopy and culture. Of the isolates, C. albicans were 2(11.11%) and Non albicans Candida (NAC) 16(88.89%). Five different NAC species were identified of which C. parapsilosis was predominant 5(27.77%) followed by C. tropicalis 4(22.22%) and C. famata 3(16.67%). Rare species of C. ciferrii 2(11.11)%, Kodamaea ohmeri 2(11.11%) were isolated. Candida spp. showed highest resistance to Clotrimazole 8(44.0%) followed by Itraconazole 6(33.0%), Nystatin 4(22.0%) and Fluconazole 3(17.0%). C. ciferrii and Kodamaea ohmeri showed resistance to all antifungals except Nystatin. Outcomes from this study showed a different picture of species distribution, with isolation of rare and emerging drug resistant threatening species like C. ciferri and Kodamea ohmeri which necessitates more detailed survey.

INTRODUCTION: Deliberate self-poisoning (DSP) is an important cause of hospital admissions and subsequent mortality. We conducted a cross-sectional observational study in a tertiary-level teaching hospital situated in the northeastern part of Bangladesh to analyze the psychosocial factors responsible for DSP. METHODS: This cross-sectional observational study was carried out among patients with DSP admitted to the medicine ward from January to December 2017, irrespective of gender, except for cases involving poisoning due to spoiled food, food contaminated by infectious organisms, poisoning by venomous animals, and street poisoning (commuter or travel-related poisoning). Consultant psychiatrist in accordance with the Diagnostic & Statistical Manual of Mental Disorder - IV (DSM-IV) confirmed psychiatric disorders. Data were analyzed by SPSS (Statistical Package for social sciences) version 16.0 (IBM Corp., Armonk, NY). RESULTS: Total 100 patients were enrolled. Among them, 43% were male and 57% were female. The majority (85%) of the patients were young, aged below 30 years. The mean age of male patients was 26.2 years and that of females was 21.69 years. Most of the DSP patients were from the lower economic class (59%). The population sample was remarkable for students (Prevalence 37%). The highest percentage of patients (33%) had their educational status at the secondary level. The common reasons for DSP were a family problem in 31% patients, quarrel with boy/girlfriend in 20%, quarrel with a spouse in 13%, quarrel with parents or other family member in 7%, failure in examination in 6%, poverty in 3%, and unemployment in 3%. Prescription medication was the most common poison material (38%), followed by insecticides (36%), household cleaners (17%), and rodenticides (8%). Seven (7%) patients reported previous deliberate self-harm events and co-morbid psychiatric disorder was present in 30% patients among them major depressive disorder was found in 60%, and schizophrenia in 23.3% cases. CONCLUSION: DSP remains a problem mainly for the young with gender ratio-favoring females. The majority of DSPs were educated up to secondary level, unmarried, residents of rural areas, student, and belonged to the lower class. Familial disharmony and quarrel with spouse or friends were the common reason behind DSP. Prescription medication and insecticides were commonly used for DSP. Psychiatric disorders, primarily depressive disorder, and schizophrenia were common in cases of DSP.
RESUMO
Myocardial infarction among patients is a concern as young patients live longer in the aftermath of this critical illness. Still, there is a wide knowledge gap about modifiable risk factors that may help to alter the course of this extreme end of coronary artery disease spectrum among young patients. The trend of socioeconomic changes in developing countries like Bangladesh has resulted in increasing non-communicable diseases like coronary artery disease. Prevalence and risk factors of myocardial infarction among people living in a rural community are largely unknown, particularly in the younger age group. We tried to find out the risk factors differences between young and old MI groups as well as proportion of myocardial infarction among patients out of total hospitalized MI patients. This cross-sectional analytical study was done among the patients admitted to a rural cardiac center. For risk factor analysis, patients with new MI, including both non-ST-elevation and ST-elevation myocardial infarction were included according to preset inclusion and exclusion criteria. Patients were grouped as young (age ≤45 years) MI and old (age >45 years) MI. Data was collected using a questionnaire after informed consent was taken. American Heart Association's continuous dietary scoring system and Holmes Rahe Stress Scale were used to identify dietary patterns and mental stress levels, respectively, among the sample. Logistic regression analysis was performed to explore the risk factors of premature MI. On the other hand, to identify the proportion of young MI patients among the hospitalized MI patient's hospital registry was used to count the cases over almost one year. For risk factor analysis between young and old MI groups, 137 MI patients were selected according for inclusion and exclusion criteria. Out of them 62 and 75 patients were in the young and old age groups, respectively. The mean ages of younger and older groups were 39.0±5.9 years and 58.8±8.2 years, respectively. In both groups, 112(81.8%) patients were male. Only 42(30.7%) patients had BMI ≥25kg/m². In the unadjusted analysis, hypertension, family history of hypertension, consumption of fatty food, dairy products, and free-range chicken were found to be associated with premature MI. No significant difference in triglyceride, cholesterol or LDL level was found between the groups. But in the multivariate analysis, only the male gender was a significantly higher risk of premature MI (aOR 7.00; 95% CI: 1.51-42.42). Interestingly, HTN (aOR 0.46; 95% CI: 0.19-1.14) and smoking (aOR 0.26; 95% CI: 0.05-0.98) tend towards increased the risk of MI among the older age group compared to the younger group. According to hospital registry analysis, 22.9% of total MI patients admitted in the cardiac center were younger than 45 years. The incidence of myocardial infarction among young patients in rural areas in Bangladesh is probably more than what is known. Other than the male gender, which is a significant un-modifiable risk factor for young myocardial infarction patients; dietary factors, diabetes, and increased body mass index may play a vital role. On the contrary, hypertension and family history of hypertension are significantly higher among the older age group.

Congenital coronary ostial stenosis or atresia (COSA) is a spectrum of rare developmental conditions with different pathophysiologic mechanisms and clinical implications. Although COSA includes various entities, these entities have two features in common. First the defect is congenital, although it may progress during pre-natal and post natal life. Second the developmental defect may cause ostial or proximal coronary obstruction (that is stenosis or atresia). Coronary ostial stenosis or atresia affects the left coronary (L-COSA) more frequently than it does the right coronary artery. Systemic Lupus Erythematosus (SLE) is not an uncommon disease in young female, but combination of congenital coronary ostial stenosis with systemic lupus erythematosus make the case very rarer. Here we presented A 17 years old girl got admitted to Bangabandhu Sheikh Mujib Medical University, Bangladesh for evaluation of on and off chest pain of CCS-III to CCS-IV for 1 day on 17 September 2019.

The 17α-methyltestosterone is the most common synthetic hormone used in male mono-sex production of Nile tilapia, Oreochromis niloticus. The current research aimed at finding out the most effective dose of 17α-methyltestosterone to produce quality Nile tilapia fry. Soon after absorbing the yolk sac, Nile tilapia fry was fed with a mixture of commercial fish feed and 17α-methyltestosterone for 28 days. Five doses of 17α-methyltestosterone, i.e., 0 mg, 50 mg, 60 mg, 70 mg, and 80 mg per kg feed, were used to treat tilapia that has been reared for additional 90 days to compare sex reversal, development, and survival rates. Both gonad histology and Squash test were performed to expose the sex percentage of O. niloticus accurately. The highest male 94.44% was obtained at 60 mg 17α-MT/kg feed dose followed by 91.67%, 88.89%, 86.11%, and 47.22% at 70, 80, 50, and 0 mg 17α-MT/kg feed dose. The groups treated with 17α-methyltestosterone hormone showed superior growth performance in comparison to the control group. The highest weight (14.62 ± 0.59 g) and length (92.18 ± 3.01 mm) were found at 60 mg dose whereas the lowest weight (8.64 ± 0.38 g) and length (70.17 ± 3.75 mm) were in the control group. The group given 60 mg 17α-MT feed represented the highest survival rate (84.10%) among other hormone-treated groups. The study disclosed that 60 mg 17α-MT/kg feed might be treated as the optimal dose for producing quality mono-sex male tilapia in the commercial hatchery.
RESUMO
Herein, an ultra-sonication technique followed by a photoreduction technique was implemented to prepare silver nanoparticle-decorated Chitosan/SrSnO3 nanocomposites (Ag-decorated Chitosan/SrSnO3 NCs), and they were successively used as electron-sensing substrates coated on a glassy carbon electrode (GCE) for the development of a 2,6-dinitrophenol (2,6-DNP) efficient electrochemical sensor. The synthesized NCs were characterized in terms of morphology, surface composition, and optical properties using FESEM, TEM, HRTEM, BET, XRD, XPS, FTIR, and UV-vis analysis. Ag-decorated Chitosan/SrSnO3 NC/GCE fabricated with the conducting binder (PEDOT:PSS) was found to analyze 2,6-DNP in a wide detection range (LDR) of 1.5~13.5 µM by applying the differential pulse voltammetry (DPV) approach. The 2,6-DNP sensor parameters, such as sensitivity (54.032 µA µM-1 cm-2), limit of detection (LOD; 0.18 ± 0.01 µM), limit of quantification (LOQ; 0.545 µM) reproducibility, and response time, were found excellent and good results. Additionally, various environmental samples were analyzed and obtained reliable analytical results. Thus, it is the simplest way to develop a sensor probe with newly developed nanocomposite materials for analyzing the carcinogenic contaminants from the environmental effluents by electrochemical approach for the safety of environmental and healthcare fields in a broad scale.

Purpose: Elderly patients are at high risk of fatality from COVID-19. The present work aims to describe the clinical characteristics of elderly inpatients with COVID-19 and identify the predictors of in-hospital mortality at admission. Materials and Methods: In this retrospective, multicenter cohort study, we included elderly COVID-19 inpatients (n = 245) from four hospitals in Sylhet, Bangladesh, who had been discharged between October 2020 and February 2021. Demographic, clinical, and laboratory data were extracted from hospital records and compared between survivors and nonsurvivors. We used univariable and multivariable logistic regression analysis to explore the risk factors associated with in-hospital death. Principal Results. Of the included patients, 202 (82.44%) were discharged and 43 (17.55%) died in hospital. Except hypertension, other comorbidities like diabetes, chronic kidney disease, ischemic heart disease, and chronic obstructive pulmonary disease were more prevalent in nonsurvivors. Nonsurvivors had a higher prevalence of leukocytosis (51.2 versus 30.7; p=0.01), lymphopenia (72.1 versus 55; p=0.05), and thrombocytopenia (20.9 versus 9.9; p=0.07). Multivariable regression analysis showed an increasing odds ratio of in-hospital death associated with older age (odds ratio 1.05, 95% CI 1.01-1.10, per year increase; p=0.009), thrombocytopenia (OR = 3.56; 95% CI 1.22-10.33, p=0.019), and admission SpO2 (OR 0.91, 95% CI 0.88-0.95; p=0.001). Conclusions: Higher age, thrombocytopenia, and lower initial level of SpO2 at admission are predictors of in-hospital mortality in elderly patients with COVID-19.
RESUMO
INTRODUCTION: Large-scale vaccination is considered one of the most effective strategies to control the pandemic of COVID-19. Since its start, different complications have been described thought to be related to vaccination. Here, we present a rare case where encephalopathy, myocarditis, and thrombocytopenia developed simultaneously following the second dose of Pfizer-BioNTech mRNA vaccine (BNT162b2). CASE PRESENTATION: A 15-years-old female presented with fever, altered consciousness, and convulsions after taking the second shot of the vaccine. Clinical and laboratory workup was notable for the presence of thrombocytopenia and myocarditis. No alternative causes of encephalitis were found. The patient responded significantly to methylprednisolone suggesting underlying immune pathogenesis responsible for the clinical features. The diagnostic criteria for possible autoimmune encephalitis were also fulfilled. CONCLUSION: Although rare, the clinician should be aware of the possible adverse events following COVID-19 vaccination. Further research with large pooled data is needed to get more insight into its pathogenesis and causal relationship.

Thyroid swellings are common clinical problem throughout the world and also in Bangladesh. Most of thyroid swellings are multinodular, but a good percentage is solitary thyroid nodule. There is no robust, feasible method for malignancy differentiation has not been well established. The study evaluated thyroid nodules for risk of malignancy and compared history, clinical, sonographic features and FNAC findings with histopathology. This was a cross sectional study on 160 consecutive subjects of thyroid nodules done in the department of ENT and Head Neck Surgery of Mymensingh Medical College Hospital (MMCH), Mymensingh, Bangladesh during from July 2018 to December 2019. All patients were admitted and diagnosed by detail history, clinical examination, investigations and underwent thyroidectomy. Detailed history, clinical examination, ultrasonographic finding and FNAC variables were documented retrospectively and a mathematical model was established for malignancy prediction. In this study mean age of the patients of thyroid nodules was 37.54±11.49 years and majority of the patients were within 21-40 years of age. Frequency of thyroid nodules is more in female with male female ratio 1:7. Most of the thyroid nodules appeared in this study within 0-2 years (61.9%). In this series of thyroid nodules constituted 88.1% firm, 8.8% hard, 3.1% cystic. Among the patients 89(55.6%) cases have solitary thyroid nodule and 71(44.4%) cases have multinodular goitre Majority of the nodules were warm 57.5% followed by cold 42.5%. FNAC showed nodular goitre 72.5%, Follicular neoplasm 1.3%, Papillary carcinoma of thyroid 7.5%, colloid goitre 9.4%, suspicious papillary carcinoma 3.8% and lymphocytic thyroiditis 1.3%. In this study out of 85 solid nodule, 69(81.18%) were benign and 16(18.82%) was malignant and out of 3 cystic nodule 3(100%) were benign. In this study most of the benign and malignant nodules were predominantly solid. Study showed the malignancy is significantly (p=0.001) more in solid than cystic nodules. Final diagnosis in this study was done on the basis of histopathological reports. Out of 160 patients, histopathologically benign lesion was 120(75%) and malignant was 40(25%). Among malignant cases 36(22.5%) cases were papillary carcinoma, 1 case was medullary carcinoma and 3 cases were follicular carcinoma.

Chronic obstructive pulmonary disease (COPD) is a preventable and treatable disease characterized by airflow limitation which is irreversible or partially reversible. COPD is associated with morbidity and increased mortality. The risk of death in patients with COPD is traditionally graded with the use of the forced expiratory volume in one second (FEV1), but it correlates better with recently developed the BODE index- (B) Body mass index; (O) airflow obstruction measured by the forced expiratory volume in one second (FEV1); (D) dyspnoea measured by the modified Medical Research Council (MRC) scale; and (E) exercise capacity measured by the 6 minute walk distance (6MWD). This prospective study was conducted in outpatient department of Sheikh Sayera Khatun Medical College Hospital, Goplaganj, Bangladesh from June 2016 to November 2018. Among total 126 patients, mean age was 60.63.0±10.65, male 94 and female 32, 94 smokers, 32 non-smokers. During the study period, 20 patients died, 12 from non-respiratory causes and 8 from pulmonary causes (corpulmonale and respiratory failure). All patients died from respiratory causes had BODE score 10. The higher the BODE score points, the higher the risk of death from respiratory causes.
