Background: Tuberculosis (TB), second leading cause of mortality in India. Despite of so many efforts of National Tuberculosis Elimination Programme (NTEP), tuberculosis is still prevalent. Therefore, this study was conducted to assess socio-demographic, clinical profile and treatment outcomes of patients on fixed drug combination (FDC) daily regimen. Methods: Retrospective record-based study was conducted in two DOTS centres of Dibrugarh selected using simple random sampling. A total of 85 medical record were selected and reviewed. Information from treatment card were extracted using a pre-designed online format. Data collected were entered and analysed in SPSS version 25 software and presented using descriptive statistics. Results: Total of 85 patients records were reviewed. Gender ratio was 54.1%: 45.9% for male:female. Majority 31.8% belonged to most productive age group of 25-34 years of age. Treatment completion rate was 80%, cured rate was 18.8% while 1.2% was died. Conclusions: Male gender were reported with higher incidence of Tuberculosis. The low percentage of cure rate suggested the need for strengthening of TB services in the DOTs centres.

Objective@#This study investigated the relationship of fetuin-A with coronary calcification, carotid atherosclerosis, and mortality risk in non-dialysis chronic kidney disease (CKD). @*Methods@#The study included 135 adult patients with CKD at stages 3–5, who were divided into coronary artery calcification (CAC) and non-CAC groups. We excluded current smokers and individuals with diabetes mellitus, inflammatory conditions, liver diseases, acute kidney failure, chronic hemodialysis, and cancer. We conducted kidney function tests, complete blood counts, and measured serum levels of fetuin-A, tumor necrosis factor-alpha (TNF-α), high-sensitivity C-reactive protein (hs-CRP), interleukin-6 (IL-6), total cholesterol (TC), total triglycerides (TG), high-density lipoprotein cholesterol, and low-density lipoprotein cholesterol. Cardiac spiral computed tomography was used to calculate the CAC score, employing the Agatston method. Carotid ultrasonography was performed to assess carotid intima-media thickness (CIMT) and to detect the presence of plaques. @*Results@#CAC patients had considerably higher levels of TNF-α (p<0.001), IL-6 (p<0.001), hs-CRP (p=0.006), TC, TG, parathyroid hormone (PTH) (p<0.001) and phosphorus (p<0.001) than non-CAC patients. They also had significantly lower levels of fetuin-A (p<0.001). Fetuin-A was considerably lower in CKD subgroups as CKD progressed. Fetuin-A (p=0.046), age (p=0.009), TNF-α (p=0.027), IL-6 (p=0.005), TG (p=0.002), PTH (p=0.002), and phosphorus (p=0.004) were significant predictors of CAC. CAC and fetuin-A were strong predictors of all-cause mortality and cardiovascular (CV) mortality. Fetuin-A was a significant predictor of CIMT (p=0.045). @*Conclusion@#Fetuin-A reliably predicted CAC and CIMT. Fetuin-A and CAC emerged as significant risk factors for all-cause and CV mortality in non-dialysis CKD.

Present research work represents antiviral and antibacterial value of body fat of Saara hardwickii commonly called as spiny tailed lizard. Oil was extracted from body fats located in the ventral region of this animal using hydrocarbons e.g., n-hexane, methanol, butanol and ethyl acetate as a solvent. The antibacterial activity of lizard oil was tested against standard as well as multi-resistant lines ofEscherichia coli, Styphalococcus aureus, Pseudomonas aeruginosa and Proteus vulgaris alone and with antibiotic ampicillin. For antibacterial potential, Ethyl acetate and Butanol solvent extract showed best zone of inhibition (7mm) with P. aeruginosa and S. aureus respectively. For antiviral potential, Butanol and Methanol extract showed best HA (Hemagglutination) titer of 04 with NDV and IBV viral strain respectively. It is concluded that lizard oil has antimicrobial potential against different pathogens strains (virus, bacteria).


O presente trabalho de pesquisa apresenta a importância antiviral e antibacteriana da gordura corporal de Saara hardwickii, comumente chamado de lagarto de cauda espinhosa. O óleo foi extraído de gorduras corporais localizadas na região ventral desse animal usando hidrocarbonetos, por exemplo, n-hexano, metanol, butanol e acetato de etila, como solvente. A atividade antibacteriana do óleo do lagarto foi testada em linhagens padrão e multirresistentes de Escherichia coli, Staphylococcus aureus, Pseudomonas aeruginosa e Proteus vulgaris, de forma isolada e com antibiótico ampicilina. Para o potencial antibacteriano, acetato de etila e extrato de butanol apresentaram melhor zona de inibição (7 mm) com P. aeruginosa e S. aureus, respectivamente. Para o potencial antiviral, o extrato de butanol e o extrato de metanol apresentaram melhor título de hemaglutinação de 4 com as cepas virais NDV e IBV, respectivamente. Conclui-se que o óleo do lagarto possui potencial antimicrobiano contra diferentes cepas de patógenos (vírus e bactérias).

Abstract Due to extensive application of antibiotics as growth promoters in animal feed, antimicrobial resistance has been increased. To overcome this challenge, rumen microbiologists search for new probiotics to improve the rate of livestock production. The present study was aimed to isolate and evaluate breed-specific lactic acid bacteria (LAB) as potential animal probiotics. The current study was conducted during 10 months from July 2020 to April 2021, in which a total of n=12 strains were isolated from different samples including milk, rumen, and feces of Nilli Ravi Buffaloes. These isolates were evaluated for their antimicrobial potential against common animal pathogens (Bacillus spp., E. coli, Staphylococcus aureus, Salmonella spp., Listeria spp.). All the isolates were identified using 16S rRNA gene sequencing and the phylogenetic analyses inferred that these strains showed close relations to the species of various genera; Enterococcus lactis, Pediococcus pentosaceus, Bacillus subtilis Weissella cibaria, Weissella soli, Bacillus tequilensis, Weissella bombi, Bacillus licheniformis, Lactococcus lactis, Bacillus megaterium, Lactobacillus ruminis, and Lactococcus lactis. NMCC-Ru2 has exhibited the enormous potential of antimicrobial activity, 28 mm, for Salmonella typhimurium;23 mm for Listeria monocytogenes 21 mm for E.coil. Highest resistance was seen in NMCC-Ru2 agasint test antbiotic, like 25.5 mm for Tetracycline. Overall results revesl that the probiotic profile of isolates was achieved using standard criteria, particularly with animal probiotic properties

Introduction: Almost 25% of colorectal cancer (CRC) patients have synchronous colorectal liver metastasis (SCLM) coinciding with the disease diagnosis. Liver-first approach for the treatment of SCLM involves neoadjuvant chemotherapy, subsequent liver resection, and then primary tumor resection. This strategy is adopted as the prognosis of the disease depends mainly on the metastases, not the primary tumor. This study aims to evaluate the feasibility of the liver-first approach and clinical prognosis in managing SCLM. Materials and Methods: This retrospective study included 25 patients with SCLM from July 2015 to July 2020. All patients were subjected to a liver-first approach with an "intention-to-treat" approach. Follow-up was planned for at least 3 years. Data were collected from the hospital records and included survival rates and univariate analyses of the prognostic factors, such as gender, age, and number of chemotherapy cycles to evaluate their effect on the survival probability. Results: Nineteen patients completed the treatment paradigm. Long-term outcomes reported a median overall survival (OS) of 32 months. One-year and 3-year survival probabilities were 89.5% and 42.1%, respectively. The median disease-free survival was 13 months. The number of metastatic lesions, unilobar versus bilobar disease, and the frequency of administered chemotherapy cycles significantly affected survival (p < 0.05). Seven patients (36.84%) remained disease free (no recurrence) while 2 patients (10.53%) survived with recurrence. The overall mortality included 10 deaths (52.63%) due to recurrence. Conclusion: Synchronous colorectal liver metastasis treated with the liver-first approach achieved a notable overall advantage. However, the recurrence rate remained relatively high. (AU)

Background: The coronavirus disease 2019 (COVID-19) pandemic, caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), is increasingly drawing worldwide attention. Among multiple risk factors, obesity is one of the factors that can influence the disease severity. This study aimed to explore the impact of obesity on the severity of COVID-19 infection. Methods: This cross-sectional study was conducted in the Department of Respiratory Medicine, Bangabandhu Sheikh Mujib Medical University, Dhaka from September 2020 to February 2021. The Adult (Aged ?18 years) patients of both genders, who were COVID-19 positive, were included in this study. Ninety-one COVID-19 patients with BMI?25 kg/m2 were set as case and another ninety-one patients with BMI<25 kg/m2 were selected as control. The patient's BMI and waist circumference (WC) were recorded. Disease severity was evaluated by the management of COVID-19 disease guidelines by the World Health Organization (WHO) 2020. Results: The maximum patients were male (65.38%), in the sixth and seventh decades. The proportion of severe illness was higher in the obese group 69.2% compared to the non-obese 47.3%. Patients with obesity require more ICU support (15.4% versus 5.5%) and invasive mechanical ventilation (9.9% versus 2.2%) compared to non-obese patients. In multivariate logistic regression analysis, after adjusting age, diabetes mellitus, and hypertension, obesity (BMI>25 kg/m2) was an independent risk factor for severe illness. Conclusions: Obese patients are associated with severe COVID-19 pneumonia. As BMI increases, disease severity increases, needs more ICU support, and needs more invasive mechanical ventilation.

Background: The Corona Virus (SARS-COV2) is one of the major pathogens that affect the human respiratory system. As it spreads via droplets, healthcare workers are at increased risk of acquiring the infection. Nursing students who are exposed to the hospital setting during their clinical postings are prone to infection because they may provide care to patients who are suspected of or diagnosed with COVID-19 infection. In dentistry, the use of hand pieces and ultrasonic instruments during dental procedures unavoidably result in generation of blood and saliva droplets. Objective was to estimate the prevalence of COVID-19 infection among Dental and Nursing students of Government dental college and nursing college, Alappuzha. Methods: A cross sectional study was conducted in Dental and Nursing students of Government TD Dental College and Nursing College, Alappuzha in November 2021. Convenient sampling was done and persons who were willing to take part in the study were distributed with a pretested questionnaire via Google Form and data was collected and analysed. Results: Out of the 174 study participants, 77 were Dental students and 97 were Nursing students, 33% of Dental students and 36% of Nursing students reported of being infected with COVID-19 virus. Significant association was obtained between COVID-19 infection and contact with Covid positive case. Conclusions: Prevalence of COVID-19 infection among Dental and Nursing students was 35.10%. Prevalence of COVID-19 infection among Dental students and Nursing students were 33% and 36% respectively.

Background: Tuberculous pleural effusion (TPE) is the most common etiology of exudative pleural effusion in high tuberculosis burden countries like Bangladesh. The usefulness of pleural fluid cholesterol for the diagnosis of TPE is not evaluated yet. This study aimed to assess the usefulness of pleural fluid cholesterol for the diagnosis of TPE. Methods: This cross-sectional study was conducted at the department of respiratory medicine at Bangabandhu Sheikh Mujib medical university. A total of thirty-five TPE was included in this study. Pleural fluid aspiration followed by cytological (total count, differential count), and biochemical (protein, glucose, lactate dehydrogenase, adenosine deaminase, and cholesterol) investigations were done. At the same time, blood was sent for biochemical (protein, glucose, and lactate dehydrogenase) investigation. Pleural biopsy followed by a histopathological examination was done to confirm TPE. Ethical clearance was obtained from the institutional review board (IRB) prior to starting this study. Results: In our study, the mean age of the participants was 35.54±14.13 years, and male predominant (74.3%). The mean pleural fluid cholesterol was 99.87±23.82 mg/dl. With a cut of value 69.85, the sensitivity, specificity, and accuracy were 97.14%, 57.14%, and 77.14% respectively. Conclusions: Pleural fluid cholesterol has significant diagnostic usefulness for the diagnosis of tuberculous pleural effusion.

The pigmentation of oral soft tissues is predominantly an aesthetic problem because lifestyle, media, and social influences impact people's perception of beauty, which in turn affects their self-esteem as well as their relationships. The melanin pigmentation of the gingiva has become a real concern in the Gulf region, especially for younger people and females, who seek aesthetic solutions to remove the pigmentation. The pigmentation caused by melanin can be removed by surgical blades, diamond burs, chemicals, and lasers, among other methods. A systematic literature review from 2012 to 2022 was performed using databases such as PubMed, Medline, and Sciencedirect. The keywords used were “Diode laser”, “Erbium laser”, and “Melanin pigmentation”. PRISMA flowchart was used to describe the selection process of searched articles. Findings revealed that 6 out of 8 studies listed superior characteristics and treatment outcomes of diode lasers as compared to Erbium lasers. It can be concluded that the diode laser is the better option to treat gingival melanin pigmentation as compared to the Erbium lasers.

Background: Abnormal uterine bleeding is a common complaint in most women of different ages that prompts seeking gynecologic care. This study aimed to analyze and age-classify the prevalence of endometrial pathologies in women with abnormal uterine bleeding.Methods: This is a cross-sectional and a descriptive study, conducted at the obstetrics and gynecology department of the American Mission Hospital in the Kingdom of Bahrain on 88 patients who presented with abnormal uterine bleeding between January 2019 and January 2020.Results: Eighty-eight women with abnormal uterine bleeding demonstrated a fluctuating pattern of twenty endometrial pathologies distributed among five age groups in the range of 30-71. The mean age of the study cohort was 44.9±7.65 years; 55% of which were reported in the 41-50 age group. Benign endometrial polyp was reported as the most common pathology, accounting for 47.8% of the cohort. Although benign endometrial polyp was significantly the highest overall finding in all three age groups younger than 60, disordered proliferative endometrium was the highest reported single pathology in the age group 41-50, (N=10, p?0.0001).Conclusions: This study demonstrated that benign endometrial polyp was the most common finding in women with abnormal uterine bleeding. This information could be essential for patient guidance and awareness of the benefits of endometrial biopsy. Eventually, the prediction of the potential endometrial pathology in women with abnormal uterine bleeding is vital for early disease management.

Different blood components are associated with various types of adverse transfusion reactions and are linked to several factors including the number, rate and volume of transfusions. The given study was conducted to study the relationship between various transfusion reactions and its causative factors. This study was a prospective study carried out over eighteen months on all patients who received a blood transfusion and blood components including various adverse reactions and events related to transfusion. These were correlated with tests for compatibility including general blood picture ,tests for haemolysis ,hematuria and haemoglobinuria, Coombs Test (Direct and Indirect), culture along with relevant clinical details of the patient. Out of a total of 31451 units of blood issued, 47 adverse transfusion reactions were noted with a maximum number in the age group of > 18 years (87.3%) with M: F being 1.6: 1 .0.24% of adverse transfusion reactions were by Packed red blood cell transfusion and mostly were immediate transfusion with a mean volume of 100 ml and mean time of 20 minutes. Febrile Non Hemolytic Transfusion Reaction (FNHTR) was the most common Adverse Transfusion Reaction (ATR)(0.128%) with 2 cases positive for Direct Coombs Test. A thorough serological and immunological examination and the addition of methods like buffy coat reduction and leucocyte filtration help in reducing the incidences of hemolytic transfusion reactions and transmitted infections and establishing a hemovigilance system help in the attainment of the goal of safe transfusion

Aims: The purpose of this study was to evaluate whether there are any significant toxic effects of the widely exposed metals on different organs (gill, liver, kidney, and muscle) of some commercially important marine fish species (Herpodon nehereus, Pampus chinensis and Hilsa ilisha). Study Design: The collection of the samples was done from January to March 2018 from Bay of Bengal near Chattogram city of Bangladesh. The study is based on randomly collected samples from the intended sampling sites (Randomized Block Design) to ensure the evenness and unbiases of the collected samples. Methodology: Analyses were performed for metals such as arsenic (As), lead (Pb) and chromium (Cr) using Atomic Absorption Spectrophotometer (AAS). During each month, five individuals each with three replications from the three targeted species were collected, with a total of 135 (45*3) fishes in the study period. Results: The concentrations of the metals found in the fishes varied in the following ranges: As: 0.029-0.071 ppm, Pb: 0.008-0.083 ppm and Cr: 0.0001-0.03 ppm. The obtained result revealed the highest concentrations of all three metals were recorded in H.nehereus fish. The organ wise lead concentration was recorded highest in kidneys and gills of examined fishes with significant variation in muscles and liver. The scenario depicted quite differently in case of chromium where concentration in gills was found to be the highest with insignificant variation in accumulation in other three organs. In case of Arsenic, kidneys and livers were the most exposed two organs in comparison to significant exposure to muscles and gills. The obtained values of arsenic accumulation were considered critical for human consumption as it was higher than the recommended values stated by WHO and FAO; but the concentration of lead and chromium were found to be safe for human consumption. The values recorded for lead were increasingly approached to the safety values. Conclusion: So, crucial steps should be taken regarding safety and environmentally friendly discharge of arsenic and lead; high levels of pollution will not only affect aquatic life but will also invite socio-economic disasters.

Patients and Methods: A cross-sectional study of 502 consenting hypertensive adults receiving care at the Irrua Specialist Teaching Hospital, Irrua in Edo State, South-south Nigeria. A pre-tested semi-structured interviewer-administered questionnaire was used to collect data which was analyzed using SPSS version 21 and the level of significance was set at P < 0.05. Results: Five hundred and two participants (226 males, 276 females) completed the study with a mean age of 52.98 ± 12.82 years. Optimal blood pressure control was found in 15.5% of the study participants. Blood pressure control was significantly associated with being married (OR 1.549, CI: 1.040­2.309), having a monthly household income of over N50,000 (OR 1.691, CI: 0.999-2.863), engaging in physical activity (OR = 1.537, CI: 0.989-2.388), and not being obese evidenced by a normal Waist Hip Ratio (OR = 2.276, CI: 1.555-3.332). Conclusion: Blood pressure control to target goal was low in the study population and achieved only in less than one­fifth of respondents on antihypertensive therapy. Numerous socio-demographic and lifestyle variables were shown to be associated with blood pressure control. Physicians should emphasize medication adherence and lifestyle modification approaches in hypertensive adults.

Background: Sickle cell disease (SCD) is associated with chronic haemolysis, immuno-suppression and susceptibility to infections, which may trigger infection-associated haemolysis (IAH). SCD patients are vulnerable to anaemic effect of IAH due to vicious interaction between pre-existing 'inherited' chronic haemolysis and 'acquired' IAH. IAH in SCD manifests as febrile haemolytic crisis with clinical and laboratory features of severe anaemia or pancytopenia. Clinico-pathological perspectives of IAH in SCD are fragmented. This review presents a comprehensive but concise overview of pathogenesis, management and prevention of IAH in SCD. Methodology and results: Online literature search using search terms such as 'sickle cell disease, viral, bacterial, parasitic, fungal, infections, hyperhaemolytic crisis, haemophagocytic syndrome, severe anaemia, pancytopenia' in various combinations was done on PubMed/Medline, Google, Google-Scholar and Bing. Overall, 112 relevant publications were retrieved, which included 109 peer reviewed journal articles, 2 World Health Organization (WHO) technical reports, and 1 edited text book. A range of bacterial (Bartonella spp, Mycoplasma spp., Mycobacterium avium complex), viral (Dengue, SARS-CoV-2, Parvovirus-B19, Cytomegalovirus, Epstein-Barr virus), parasitic (Plasmodium spp., Babesia spp.), and fungal (Histoplasma spp.) infections were associated with IAH in SCD. There are two broad types of IAH in patients with SCD; infection associated extra-medullary haemolysis (IAEMH) and infection associated intra-medullary haemolysis (IAIMH). While IAEMH is associated with severe anaemia due to intravascular haemolysis caused by red cell invasion, oxidative injury, auto-antibodies, and/or pathogen-haem interaction, IAIMH is associated with haemophagocytic tri-lineage destruction of haematopoietic precursors in the bone marrow. Conclusion: Various microbial pathogens have been associated with IAH in SCD. SCD patients with fever, severe anaemia or pancytopenia should be investigated for early diagnosis and prompt treatment of IAH, which is a lifethreatening haematological emergency for which transfusion therapy alone may not suffice. Prompt and sustainable termination of IAH may require therapeutic combination of transfusion, anti-microbial chemotherapy, and immune modulation therapy. SCD patients should also receive counselling on hygiene, barrier protection against vectors, routine chemoprophylaxis for locally endemic diseases, and immunization for vaccine-preventable infections as a long-term preventive strategy against IAH.
