Lipid Association of India 2023 update on cardiovascular risk assessment and lipid management in Indian patients: Consensus statement IV.

OBJECTIVE: In 2016, the Lipid Association of India (LAI) developed a cardiovascular risk assessment algorithm and defined low-density lipoprotein cholesterol (LDL-C) goals for prevention of atherosclerotic cardiovascular disease (ASCVD) in Indians. The recent refinements in the role of various risk factors and subclinical atherosclerosis in prediction of ASCVD risk necessitated updating the risk algorithm and treatment goals. METHODS: The LAI core committee held twenty-one meetings and webinars from June 2022 to July 2023 with experts across India and critically reviewed the latest evidence regarding the strategies for ASCVD risk prediction and the benefits and modalities for intensive lipid lowering. Based on the expert consensus and extensive review of published data, consensus statement IV was commissioned. RESULTS: The young age of onset and a more aggressive nature of ASCVD in Indians necessitates emphasis on lifetime ASCVD risk instead of the conventional 10-year risk. It also demands early institution of aggressive preventive measures to protect the young population prior to development of ASCVD events. Wide availability and low cost of statins in India enable implementation of effective LDL-C lowering therapy in individuals at high risk of ASCVD. Subjects with any evidence of subclinical atherosclerosis are likely to benefit the most from early aggressive interventions. CONCLUSIONS: This document presents the updated risk stratification and treatment algorithm and describes the rationale for each modification. The intent of these updated recommendations is to modernize management of dyslipidemia in Indian patients with the goal of reducing the epidemic of ASCVD among Indians in Asia and worldwide.

Estimation of 10-Year Fracture Risk with and without Bone Mineral Density in Patients with Rheumatoid Arthritis.

Rheumatoid arthritis (RA) is the most common inflammatory arthritis affecting 0.5-1.0% of the general population worldwide and although RA is properly considered a disease of the joints, it can cause a variety of extra-articular manifestations. This study was performed to find out any discrepancy in fracture risk estimates with and without bone mineral density (BMD) in rheumatoid arthritis (RA) patients. This observational cross-sectional study was carried out in the Department of Rheumatology, Bangabandhu Sheikh Mujib Medical University (BSMMU), Bangladesh from July 2013 to July 2015. Total 65 consecutive patients with RA fulfilling ACR/EULAR criteria aged 40-90 year were recruited. Ten year fracture risk of these patients was evaluated by the FRAX score with and without BMD and differences were observed. FRAX score without BMD revealed that major fracture risk was low in 58(89.2%) patients, moderate in 7(10.8%) patients but re-estimation with BMD revealed that 55(84.6%) patients remained in low risk group, 8(12.3%) patients in moderate risk group and 2(3.1%) patients went to the high risk group. In case of hip fracture risk without BMD, risk was low in 58(89.2%) patients, high in 7(10.8%) patients; but with BMD, 50(76.9%) patients remained in low risk group but risk of 15(23.1%) patients became high. Almost all the high risk patients (93.3%) were ≥55 years of age. Increasing age, female sex, disease duration and use of steroid were positively correlated with increased FRAX score where as high BMI and high BMD were associated with low FRAX score. But in multivariate analysis it was found that only relation with age was at statistically significant level. Significant numbers of patients with rheumatoid arthritis have high risk of fracture especially hip fracture. The mean of FRAX score increased in both major & hip osteoporotic fracture risk after adding BMD. More than half of the patients above fifty five years or more had high risk of fracture. So, BMD should be done in patients aged more than fifty five.

Climate change and non-migration - exploring the role of place relations in rural and coastal Bangladesh.

Of growing research and policy interest are the experiences of people living under conditions of climate change-induced environmental stress, which either are unable to migrate (sometimes described as a 'trapped population') or are seemingly unwilling to do so (sometimes described as the 'voluntarily immobile'). This paper problematises and expands upon these binary categories: examining the complex dimensionality of non-migration as a form of place relations, explored through qualitative study of rural and coastal Bangladeshi communities. Through 60 semi-structured interviews of individuals from four communities in the Kalapara region, the analysis proffers four qualitatively derived and inter-related dimensions of voluntary and involuntary non-migration framed as a form of place relations. These four dimensions concern the following: (1) livelihood opportunities, (2) place obduracy, (3) risk perceptions, and (4) social-structural constraints, with the interplay between these elements explaining diverse non-migratory experiences. In our analysis, 'place obduracy' is introduced as a concept to describe the differential speed of environmental change and socio-cultural adaptation responses to explain non-migratory experiences. Our discussion provides insight into how to best support non-migrant people's adaptive capacity in the face of growing climate emergency.

POLIE suppresses telomerase-mediated telomere G-strand extension and helps ensure proper telomere C-strand synthesis in trypanosomes.

Trypanosoma brucei causes human African trypanosomiasis and sequentially expresses distinct VSGs, its major surface antigen, to achieve host immune evasion. VSGs are monoallelically expressed from subtelomeric loci, and telomere proteins regulate VSG monoallelic expression and VSG switching. T. brucei telomerase is essential for telomere maintenance, but no regulators of telomerase have been identified. T. brucei appears to lack OB fold-containing telomere-specific ssDNA binding factors that are critical for coordinating telomere G- and C-strand syntheses in higher eukaryotes. We identify POLIE as a telomere protein essential for telomere integrity. POLIE-depleted cells have more frequent VSG gene conversion-mediated VSG switching and an increased amount of telomeric circles (T-circles), indicating that POLIE suppresses DNA recombination at the telomere/subtelomere. POLIE-depletion elongates telomere 3' overhangs dramatically, indicating that POLIE is essential for coordinating DNA syntheses of the two telomere strands. POLIE depletion increases the level of telomerase-dependent telomere G-strand extension, identifying POLIE as the first T. brucei telomere protein that suppresses telomerase. Furthermore, depletion of POLIE results in an elevated telomeric C-circle level, suggesting that the telomere C-strand experiences replication stress and that POLIE may promote telomere C-strand synthesis. Therefore, T. brucei uses a novel mechanism to coordinate the telomere G- and C-strand DNA syntheses.

Angiographic outcomes in STEMI patients receiving fibrinolysis with guideline directed optimal antithrombotic therapy.

STEMI is a major public health problem requiring timely reperfusion. Fibrinolysis remains prevalent reperfusion strategy where timely primary percutaneous coronary intervention (PCI) cannot be performed. Adjunctive antithrombotic agents are of utmost importance for maximizing the benefit of fibrinolysis. This prospective study evaluates the angiographic outcomes in STEMI patients receiving fibrinolysis with optimal antithrombotic therapy and reported TIMI 3 flow rates of 33.8% and 41.5% for streptokinase and reteplase respectively, that were significantly higher than various prior studies. This data reiterates the utility of thrombolysis in resource limited settings.

Correlation of eGFR By MDRD and CKD-EPI Formula with Creatinine Clearance Estimation in CKD Patients and Healthy Subjects.

This cross sectional comparative study was conducted in the Nephrology and Medicine outdoor and in-patients department of Mymensingh Medical College Hospital, Bangladesh from April 2014 to March 2015. A total of 100 patients with CKD and 100 healthy subjects were included in the study. Data were collected by interview of the patients, clinical examination and laboratory investigations using a semi-structured case record form. Among all subjects, 50.0% had no CKD and 50.0% patients had CKD: Stage 3 CKD were 8.5%, CKD Stage 4 CKD were 21.0%, CKD Stage 5 CKD were 20.5%. Serum creatinine was 4.32±3.08mg/dl in patients with CKD and 1.00±0.22mg/dl was in healthy subjects. Mean±SD of CCR/ml/min was found 17.67±11.63ml/min in patients with CKD and 79.31±13.31ml/min was found in healthy subjects. On the other hand, Mean±SD CCCR/ml/m/1.73m² was found 19.79±12.85 ml/m/1.73m² in patient with CKD and healthy subjects had 83.83±13.33 ml/m/1.73m². Urinary creatinine was 45.59±15.63 & 57.66±11.45mg/dl respectively. CKD-EPI eGFR was 22.10±15.02 & 90.61±23.27ml/m/1.73m²; MDRD eGFR was 22.15±14.18 & 89.35±26.19 ml/m/1.73m² respectively. Difference between all the variables between CKD group and healthy group was found statistically significant (p<0.001). CKD-EPIeGFR and MDRDeGFR were increased both in CKD patients and healthy subjects in respect to CCR and CCCR. There was a strong positive correlation between CCCR (ml/m/1.73m2) and CKD-EPI (ml/m/1.73m²) among all patients (r=0.934 and p<0.001) and also a positive correlation of CCCR with MDRD among all patients (r=0.913 and p<0.001). A positive correlation of CCCR was found with CKD-EPIeGFR among CKD patients (r=0.848 and p<0.001). A positive correlation of CCCR was also found with MDRDeGFR among CKD patients (r=0.841, p<0.001). There are positive correlations between CCCR and CKD/EPI among healthy subjects (r=0.616 and p<0.05) and between CCCR with MDRD among healthy subjects (r=0.568 and p<0.05). Various formulae were used to calculate GFR on the basis of serum creatinine levels. The Overall correlation of population (healthy and CKD patients) between CCCR and CKD EPI and MDRD formula was (r=0.93 and 0.91) respectively, among CKD patients it was (r=0.848 and r=0.841) in healthy subjects it was (r=0.616 and r=0.568) respectively. CKD EPI eGFR and MDRD eGFR formula had fairly good correlation with conventional 24 hours creatinine clearance in both CKD patient and healthy subjects, there was even more strong correlation especially in CKD patients. The performance of CKD-EPI equation is better than MDRD equation to estimate the eGFR in both CKD patients and healthy subjects.

Lodosocoris santhae sp. nov is described and illustrated based on male and female genitalia. The diagnostic characters of the new species are compared with L. azhari.

Trypanosoma brucei RAP1 Has Essential Functional Domains That Are Required for Different Protein Interactions.

RAP1 is a telomere protein that is well conserved from protozoa to mammals. It plays important roles in chromosome end protection, telomere length control, and gene expression/silencing at both telomeric and nontelomeric loci. Interaction with different partners is an important mechanism by which RAP1 executes its different functions in yeast. The RAP1 ortholog in Trypanosoma brucei is essential for variant surface glycoprotein (VSG) monoallelic expression, an important aspect of antigenic variation, where T. brucei regularly switches its major surface antigen, VSG, to evade the host immune response. Like other RAP1 orthologs, T. brucei RAP1 (TbRAP1) has conserved functional domains, including BRCA1 C terminus (BRCT), Myb, MybLike, and RAP1 C terminus (RCT). To study functions of various TbRAP1 domains, we established a strain in which one endogenous allele of TbRAP1 is flanked by loxP repeats, enabling its conditional deletion by Cre-mediated recombination. We replaced the other TbRAP1 allele with various mutant alleles lacking individual functional domains and examined their nuclear localization and protein interaction abilities. The N terminus, BRCT, and RCT of TbRAP1 are required for normal protein levels, while the Myb and MybLike domains are essential for normal cell growth. Additionally, the Myb domain of TbRAP1 is required for its interaction with T. brucei TTAGGG repeat-binding factor (TbTRF), while the BRCT domain is required for its self-interaction. Furthermore, the TbRAP1 MybLike domain contains a bipartite nuclear localization signal that is required for its interaction with importin α and its nuclear localization. Interestingly, RAP1's self-interaction and the interaction between RAP1 and TRF are conserved from kinetoplastids to mammals. However, details of the interaction interfaces have changed throughout evolution.IMPORTANCETrypanosoma brucei causes human African trypanosomiasis and regularly switches its major surface antigen, VSG, to evade the host immune response. VSGs are expressed from subtelomeres in a monoallelic fashion. TbRAP1, a telomere protein, is essential for cell viability and VSG monoallelic expression and suppresses VSG switching. Although TbRAP1 has conserved functional domains in common with its orthologs from yeasts to mammals, the domain functions are unknown. RAP1 orthologs have pleiotropic functions, and interaction with different partners is an important means by which RAP1 executes its different roles. We have established a Cre-loxP-mediated conditional knockout system for TbRAP1 and examined the roles of various functional domains in protein expression, nuclear localization, and protein-protein interactions. This system enables further studies of TbRAP1 point mutation phenotypes. We have also determined functional domains of TbRAP1 that are required for several different protein interactions, shedding light on the underlying mechanisms of TbRAP1-mediated VSG silencing.

Comparison of Serum Amylase and Lipase Levels between Predialysis and Maintenance Haemodialysis CKD Patients.

This cross sectional study was done to compare serum levels of amylase and lipase between predialysis and maintenance haemodialysis chronic kidney disease (CKD) patients and also to find out their relationship between degrees of renal impairment in Mymensingh Medical College Hospital and National Institute of Kidney Diseases and Urology, Dhaka, Bangladesh from May 2016 to April 2017. A total of 80 patients were included purposively as study subjects and made into two groups namely predialysis CKD group comprising 50 patients and other as maintenance haemodialysis group comprising of 30 patients. Among the predialysis group majority of the CKD was caused by glomerulonephritis (48%) followed by diabetes (26%), HTN (2%) and large portion undiagnosed (24%) whereas in the haemodialysis group ESRD was caused by diabetes (46%) followed by glomerulonephritis (16%), HTN (13%) and undiagnosed (23%). This study showed that mean serum amylase (158±718U/L vs. 111±41U/L) did not significantly differ between study groups except being above reference level but serum lipase (739±888U/L vs. 434±214U/L) was significantly higher in the predialysis group. There was a correlation between rising serum creatinine with serum amylase and lipase.

Clinical and Laboratory Profile of Dengue Fever in a North Indian Tertiary Hospital.

Objectives: The present study was done to ascertain the presentations of dengue fever in a North Indian tertiary care Hospital, and to compare the clinical and laboratory features among patients with and without warning signs in dengue fever. Methods: A total of 600 patients of dengue admitted to medical wards were included in the study. A detailed history as well as a general and systemic clinical examination were carried out. Haematological profiles and biochemical investigations were done at the time of admission and were followed daily or at times twice a day. Signs of plasma leakage were assessed by chest radiograph and abdominal ultrasonography, serum albumin etc. Patients were classified as dengue fever without warning signs and with warning signs and laboratory diagnosis of dengue was established by demonstration of NS1 antigen and specific antibodies to dengue in serum. Results: Of the 600 dengue positive patients, 421 (70.2%) were males and 179 (29.8%) were females. Mean age of the patients was 27.35±11.43 years. Among all patients of dengue, 21 (3.5%) presented with bleeding from any site. Out of these, only 7 of those presenting without warning signs had bleeding episodes whereas, 22 (34.3%) of patients presenting with warning signs had bleeding and this difference was statistically significant (p=0.01). Haematocrit was an important factor to predict severity of dengue. Whereas the mean haematocrit among all patients was 39.79±3.23%, it was 39.49±4.25% among those without warning signs and 42.22±3.54% among those with warning signs of dengue, and this was significant statistically, with a p-value of 0.002. Conclusion: Early diagnosis, monitoring and prompt supportive management can reduce mortality in dengue. In the present study, it was found that newer signs and symptoms are emerging and may cause delay in the diagnosis. It was found that the mortality rate was significantly higher in patients of dengue with warning sign.

Prevalence of Microalbuminuria and Overt Proteinuria in Diabetes Mellitus and their Association with Renal Function.

This cross sectional observational study was conducted in the Department of Nephrology, Mymensingh Medical College Hospital, Mymensingh, Bangladesh from April 2009 to March 2010. Samples were collectedfrom rural area of Khalishaur union of Purbadhala upazilla in Netrakona District, 30km away from Mymensingh Town. The main objective of the study was to find out the prevalence of microalbuminuria as well as overt proteinuria in diabetes mellitus in a rural population and to observe their association with renal function. In this study 1048 adult participants of 18 to 65 years in a rural area of Netrakona were included purposively as study subjects. Among them 54% were male and 46% were female. Mean age of study subjects was 42.4±13.4 years. Prevalence of microalbuminuria among diabetic participants was 29.72% where as in non diabetic non hypertensive participants it was 6.62%. Diabetic persons 9.45% and 3.9% of non diabetic participants showed overt proteinuria by dipstick test. Prevalence of hypertension in diabetic and non diabetic participants was 45.94% and 16.52% respectively. The mean eCCr of the diabetic patients and non-microalbuminuric healthy persons was 78.4±25.4 ml/min/1.73m² and 94.67±24.8 ml/min/l.73m² respectively according to Cock Croft-Gault equation. The mean eCCr of diabetic participants with overt proteinuria was 57.44±28.33 ml/min/l.73m² but diabetic patients with microalbuminuria had better mean eCCr 80.62±21.17 ml/min/1.73m² which justifies the importance of detection of microalbuminuria for early intervention. By regression analysis it was found that degree of microalbuminuria had linear relation with renal function and random blood sugar level. Neither BMI nor duration of diabetes showed any correlation with urine microalbumin. There was no effect of sex on the prevalence of microalbuminuria in diabetes mellitus. Microalbuminuria is the first sign of renal involvement in diabetic patients which is a risk factor for overt nephropathy. Monitoring of this condition is important because early treatment of microalbuminuria can prevent or postpone overt nephropathy.

Seroprevalence of Bluetongue Virus in small ruminants in Balochistan province, Pakistan.

Bluetongue (BT), caused by bluetongue virus (BTV), is a vector-borne disease of small ruminants that has the potential to spread across international borders. Despite large populations of susceptible animals and borders with BTV endemic countries, little is known of the disease burden and prevalent serotypes in the province of Balochistan in Pakistan. We conducted a cross-sectional study to determine seroconversion and prevalent serotypes in selected districts of the province using a competitive enzyme-linked immunosorbent assay (cELISA) and real-time polymerase chain reaction (RT-PCR). Sera (n = 876) were collected from clinically healthy sheep and goats originating from the districts of Quetta (n = 300), Mastung (n = 201), Killa Saifullah (n = 75) and Kech (n = 300). None of the study herds (n = 97) were seronegative for BTV, and at the individual level, the overall prevalence of BTV seroconversion was 47.26% (n = 414/876, 95% CI = 43.92%-50.63%). A higher percentage of goats (50.87%, 95% CI = 45.99%-55.73%) were seropositive for anti-VP7 immunoglobulins (IgG) than sheep (44.21%, 95% CI = 39.81%-48.70%). Odds ratios of seroconversion for goats were associated with breed type (χ2  = 16.84, p = .01), parity (χ2  = 23.66, p = .00) and presence of vector (χ2  = 2.63, p = .10), whereas for sheep, it was associated with breed type (χ2  = 13.80, p = .01) and parity (χ2  = 53.40, p = .00). Serotype 8 was the most prevalent (26.82%, 95% CI = 14.75%-43.21%) followed by an equal prevalence of serotypes 2 and 9 (7.31%, 95% CI = 1.91%-21.01%). To the best of our knowledge, this is the first study conducted in Balochistan province and the results indicate that there is a necessity to initiate intervention strategies to control BT disease burden not only in this region of Pakistan but also in adjacent areas of the neighbouring countries, Iran and Afghanistan.

Removal of dibutyl phthalate from aqueous environments using a nanophotocatalytic Fe, Ag-ZnO/VIS-LED system: modeling and optimization.

An (Fe, Ag) co-doped ZnO nanostructure was synthesized by a simple chemical co-precipitation method and used for the degradation of dibutyl phthalate (DBP) in aqueous solution under visible light-emitting diode (LED) irradiation. (Fe, Ag) co-doped ZnO nanorods were characterized by powder X-ray diffraction, Fourier transform infrared spectroscopy, UV-VIS diffuse reflectance spectroscopy, elemental mapping, Field emission scanning electron microscopy, transmission electron microscope and Brunauer-Emmett-Teller surface area analysis. A Central Composite Design was used to optimize the reaction parameters for the removal of DBP by the (Fe, Ag) co-doped ZnO nanorods. The four main reaction parameters optimized in this study were the following: pH, time of radiation, concentration of the nanorods and initial DBP concentration. The interaction between the four parameters was studied and modeled using the Design Expert 10 software. A maximum reduction of 95% of DBP was achieved at a pH of 3, a photocatalyst concentration of 150 mg L-1 and a DBP initial DBP concentration of 15 mg L-1. The results showed that the (Fe, Ag) co-doped ZnO nanorods under low power LED irradiation can be used as an effective photocatalyst for the removal of DBP from aqueous solutions.

Role of water chemistry and stabilizers on the Vero-cells-based infectivity of Newcastle disease virus live vaccine.

Newcastle disease virus (NDV) live vaccines are supplied in lyophilized form and usually administered through conventional routes (drinking water, spray, or eye drop) following reconstitution in a diluent. Virus inactivation due to physico-chemical properties of the diluent at the time of administration may lead to vaccine failure. The present study aimed to evaluate the survival of NDV live vaccine strain immersed in 5 pH-amended water samples (pH 5.00, pH 6.00, pH 7.00, pH 8.00, and pH 9.00) by sequential determination of virus infectivity on Vero cells for 3 hours. Minimum reduction in virus infectivity was recorded in the water with neutral or slightly alkaline pH, while the virus was relatively less stable at extreme pH conditions. Maximum reduction of infectivity was observed in the water with pH 9.00 in which the virus was completely inactivated within 3 hours. Addition of stabilizers (Cevamune® or skimmed milk) slightly altered the pH and total dissolved solids (TDS) values of the virus-charged water samples. In the stabilizer-added water samples, minimum reduction in infectivity was observed in the water with neutral pH, followed by the ones with a pH of 8.00, 6.00, 5.00, and 9.00. In all types of water samples, T-90 values (time required for 90% reduction in virus infectivity) were highest (485 minutes) at neutral pH (pH 7.00) and lowest (102 to 134 min) at an extreme alkaline condition (pH 9.00). Results of the present study indicate that water with a pH range of 7.00 to 8.00 is suitable for administration of NDV live vaccines. However, the addition of Cevamune® or skimmed milk may have beneficial effects on preserving the infectivity of the virus, even at extreme pH conditions.
