RESUMO

Coronary Artery Disease (CAD) is a global health concern, with diagnostic modalities and risk factors that exhibit regional variations. This study, conducted at the Islamabad Diagnostic Center, Pakistan, aimed to provide a comprehensive assessment of CAD prevalence, severity, and associated risk factors, while also evaluating the diagnostic accuracy of Computed Tomography Coronary Test (CTT) and Exercise Treadmill Test (ETT) in a cohort of 2909 patients. Among the patients assessed via CT Coronary scans, CAD was universally observed, presenting with varying degrees of severity. Our findings indicated that 24.5% of patients had mild CAD, 28.6% exhibited mild to moderate CAD, 16.3% were diagnosed with moderate CAD, 18.4% demonstrated moderate to severe CAD, and 20.4% displayed severe CAD. This spectrum underscores the diverse nature of CAD within the study population. In addition to CTT, we conducted a detailed evaluation of ETT results in 49 patients. These results revealed that 55.1% of patients tested positive for ischemia during the exercise test, emphasizing the prevalence of cardiac stress and underlying CAD. Conversely, 32.7% of patients exhibited negative ETT results, indicating favorable cardiac tolerance during physical activity. A subset of patients yielded non-diagnostic or inconclusive results, necessitating further clinical assessment. Disease history analysis showed a dichotomy within the cohort, with 20.4% having a known medical history and 79.6% possessing an unknown disease history, highlighting the importance of comprehensive medical records in clinical practice. Hypertension, a critical cardiovascular risk factor, was identified in 87.8% of patients, underscoring its significance. Smoking history displayed notable variation, with 69.4% categorized as smokers, 14.3% as ex-smokers, and 10.2% as non-smokers. Lipid profile analysis indicated that 69.4% of patients had abnormal lipid levels. To assess the diagnostic accuracy of CTT and ETT, we calculated Positive Predictive Values (PPV) and Negative Predictive Values (NPV). CTT exhibited a PPV of approximately 5.99% and an NPV of approximately 4.40%, whereas ETT displayed a higher PPV of around 26.44% and a substantially higher NPV of about 49.24%. This study offers valuable insights into CAD prevalence, severity, and associated risk factors in a Pakistani cohort, emphasizing the importance of holistic risk assessment and tailored interventions in clinical practice. Our findings also highlight the diagnostic utility of ETT in CAD assessment.

RESUMO

SARS-CoV-2 is recently emerged virus, which caused millions of deaths, all over the world. To tackle COVID-19 pandemic, there is an utmost need for in-depth analysis of viral replication. We aimed to examine viral load in SARS-CoV-2 patients during first two waves of COVID-19 in Pakistan. 225,615 suspected subjects from 75 different regions of Pakistan were selected in the study. SARS-CoV-2 RNAs were detected via real time PCR. During first wave (period of June-July, 2020) of COVID-19 the prevalence of SARS-CoV-2 was 20.38%. However, during second wave (period of November-December, 2020) of COVID-19, the rate of prevalence was 9.41%. During first wave of COVID-19 96.31% of participants remained PCR positive for 14 to 21 days, 3.39% of subjects showed positive results for 22 to 35 days, while delayed Ct values were observed among 0.26% of participants for 36 to 49 days. However, during second wave of COVID-19 89.31% of the subjects exhibited symptoms and showed real-time PCR positive results for 14 to 21 days, 9.42% showed positive results for 22 to 35 days, while significantly delayed Ct value results were observed among 1.026% of participants for 36 to 63 days (3.95 times higher than first wave). In contrast to first wave of COVID-19, the factors that were different in second wave were neither viral (different strains) nor host (same population). But treatment factors changed significantly. As during second wave besides azithromycin, corticosteroid dexamethasone consumption was increased consequently causing delayed Ct value negativity. This suggests that corticosteroid treatment might be linked with delayed Ct value or viral clearance. This study is crucial for re-considering effective therapeutic options against COVID-19.

RESUMO

Despite of the global unity against COVID-19 pandemic, the threat of SARS-CoV-2 variants on the lives of human being is still not over. SARS-CoV-2 pandemic has urged the need of rapid viral detection at earliest. To cope with gradually expanding scenario of SARS-CoV-2, accurate diagnosis is extremely crucial factor which should be noticed by international health organizations. Limited research followed by sporadic marketing of SARS-CoV-2 rapid pharmaceutical detection kits raises critical questions against quality assurance and quality control measures. Herein we aimed to interrogate effectivity and specificity analysis of SARS-CoV-2 pharmaceutical rapid detection kits (nasopharyngeal swab based) using conventional gold standard triple target real-time polymerase chain reaction (USFDA approved). A cross-sectional study was conducted over 1500 suspected SARS-CoV-2 patients. 100 real time-PCR confirmed patients were evaluated for pharmaceutical RDT kits based upon nasopharyngeal swab based kits. The SARS-CoV-2 nasopharyngeal swab based rapid diagnostic kit (NSP RDTs) analysis showed 78% reactivity. Among real time PCR confirmed negative subjects, 49.3% represented false positivity. The positive predictive analysis revealed 67.82%, while negative predictive values were 64.40%. The NSP RDTs showed limited sensitivities and specificities as compared to gold standard real time PCR. Valid and authentic detection of SARS-CoV-2 is deemed necessary for accurate COVID-19 surveillance across the globe. Current study highlights the potential consequences of inadequate detection of SARS-CoV-2 and emerging novel mutants, compromising vaccine preventable diseases. Current study emphasizes need to wake higher authorities including strategic organizations for designing adequate measures to prevent future SARS-CoV-2 epidemics.

RESUMO

Abstract Dietary habits of bandicoot rats (bandicota bengalensis) were investigated in the agricultural crops of the Pothwar Plateau, Pakistan by analysing stomach contents. The research activities were conducted in major field crops including wheat-groundnut and in the fallow lands during non-crop season at the field boundaries. The specimens were captured from the fields using kill/snap traps, and dissected to collect their stomach samples for laboratory analysis. Light microscopic slides of the plant material were recovered from stomach samples and the reference materials were collected from the field. Results revealed that the bandicoot rat predominantly fed upon cultivated crops during cropping season but consumed wild vegetation during non-cropping season. There was no significance difference between summer and winter diets. Most frequently consumed crop food items were wheat (Triticum aestivum; 28.57%), groundnut (Arachis hypogea; 11.26%), sorghum (Sorghum bicolor; 10.17%), chickpea (Cicer arietinum; 9.52%), maize (Zea mays; 6.49%), millet (Pennisetum glaucum; 5.84%), barley (Hordeum vulgare; 4.98%) and mustard (Brassica campestris; 4.98%). Among wild vegetation were consumed khbal gha (Cynodon dactylon; 7.79%), baron dhab (Demostachya bipinnata; 7.36%) and Prickly flower (Achyranthes aspera; 3.03%). The study concludes that, in addition to consuming wheat and groundnut crops, the Lesser bandicoot rat also subsists on grasses, weeds, and some fodder crops, as important component of its diet in agro-ecosystem of the Pothwar Plateau.


Resumo Os hábitos alimentares de ratos bandicoot (Bandicota bengalensis) foram investigados nas plantações agrícolas do planalto de Pothwar, Paquistão, por meio da análise do conteúdo estomacal. As atividades da pesquisa foram conduzidas nas principais culturas de campo, incluindo trigo e amendoim, e em terras de pousio durante a estação não agrícola nos limites do campo. Os espécimes foram capturados dos campos usando armadilhas kill/snap e dissecados para coletar suas amostras de estômago para análise laboratorial. Lâminas de microscopia de luz do material vegetal foram recuperadas de amostras de estômago; os materiais de referência foram coletados no campo. Os resultados revelaram que o rato bandicoot alimentava-se predominantemente de culturas cultivadas durante a época de cultivo, mas consumia vegetação selvagem durante a época de não colheita. Não houve diferença significativa entre as dietas de verão e inverno. Os alimentos agrícolas mais frequentemente consumidos foram trigo (Triticum aestivum; 28,57%), amendoim (Arachis hypogea; 11,26%), sorgo (Sorghum bicolor; 10,17%), grão de bico (Cicer arietinum; 9,52%), milho (Zea mays; 6,49%), milheto (Pennisetum glaucum; 5,84%), cevada (Hordeum vulgare; 4,98%) e mostarda (Brassica campestris; 4,98%). Entre a vegetação silvestre foram consumidos khbal gha (Cynodon dactylon; 7,79%), barão dhab (Demostachya bipinnata; 7,36%) e flor espinhosa (Achyranthes aspera; 3,03%). O estudo conclui que, além de consumir culturas de trigo e amendoim, o rato bandicoot pequeno também subsiste de gramíneas, ervas daninhas e algumas culturas forrageiras, componentes importantes de sua dieta no agroecossistema do planalto de Pothwar.

RESUMO

The Agrobacterium-mediated floral dip protocol is the most extensively used transformation method for a model plant Arabidopsis thaliana. Several useful methods for Agrobacterium tumefaciens-mediated transformations of Arabidopsis are existing, but they are time consuming and with low transformation efficiency. Here, we developed a transgenic Arabidopsis lines TET12p::TET12-RFP in a short period of time and enhanced transformation efficiency by using a modified transformation method by applying drought stress after floral dip. In this protocol, Agrobacterium cells carrying TET12p::TET12-RFP recombinant vectors were resuspended in a solution of 5% sucrose, 0.05% (v/v) silwet L-77 to transform female gametes of developing Arabidopsis inflorescences. Treated Arabidopsis were then applied with different levels of drought stresses to stimulate plants for the utilization of maximum plant energy in seed maturation process. The applied stresses achieved the fast maturation of already treated inflorescences while stopped the growing of newly arising untreated inflorescence, thus decreased the chances of wrong collection of untransformed seeds. Consequently, the collected seeds were mostly transgenic with a transformation frequency of at least 10%, thus the screening for positive transformants selection was more advantageous on a selective medium as compared to a classical floral dip method. Within 2-3 months, two hundred of individual transgenic plants were produced from just 10 infiltrated plants. This study concludes that application of drought stresses in a specific stage of plant is a beneficial strategy for achieving the transgenic Arabidopsis in a short period of time with high transformation efficiency.


O protocolo de imersão floral mediado por Agrobacterium é o método de transformação mais amplamente utilizado para uma planta-modelo Arabidopsis thaliana. Existem vários métodos úteis para transformações de Arabidopsis mediados por Agrobacterium tumefaciens, mas são demorados e com baixa eficiência de transformação. Aqui, desenvolvemos uma linha transgênica de Arabidopsis TET12p::TET12-RFP em um curto período de tempo e eficiência de transformação aprimorada usando um método de transformação modificado por meio da aplicação de estresse hídrico após o mergulho floral. Neste protocolo, células de Agrobacterium transportando vetores recombinantes TET12p::TET12-RFP foram ressuspensas em uma solução de 5% de sacarose, 0,05% (v/v) silwet L-77 para transformar gametas femininos de inflorescências de Arabidopsis em desenvolvimento. Arabidopsis tratadas foram então aplicadas com diferentes níveis de estresse hídrico para estimular as plantas a utilizar o máximo de energia da planta no processo de maturação das sementes. Os estresses aplicados alcançaram a rápida maturação das inflorescências já tratadas enquanto paravam o crescimento de inflorescências não tratadas recém-surgidas, diminuindo, assim, as chances de coleta errada de sementes não transformadas. Consequentemente, as sementes coletadas eram principalmente transgênicas, com uma frequência de transformação de pelo menos 10%; portanto, a triagem para seleção dos transformantes positivos foi mais vantajosa em um meio seletivo em comparação com um método clássico de imersão floral. Dentro de 2-3 meses, 200 plantas transgênicas individuais foram produzidas a partir de apenas 10 plantas infiltradas. Este estudo conclui que a aplicação de estresse hídrico em um estágio específico da planta é uma estratégia benéfica para alcançar a Arabidopsis transgênica em um curto período de tempo com alta eficiência de transformação.

RESUMO

The antidiabetic and hepato-renal protective effects of Citrullus colocynthis and Momordica charantia ethanol extracts were investigated in streptozotocin (STZ) induced diabetic male albino rats. Diabetic rats were treated with C. colocynthis, M. charantia or C. colocynthis + M. charantia mixed extract at a dose of 250 mg /kg body weight per oral per day for 21 days. The mean body weight of all the diabetic rat groups on day 1 of treatment (day 10 of diabetes) was significantly lower than the normal control rat group (P<0.05). The blood glucose level of all the diabetic rat groups on day 1 of treatment (day 10 of diabetes) was significantly (P<0.05) higher (> 200 mg/dl) than the normal control rat group (95.5 ± 2.7). At the end of treatment (day 21), the diabetic rats treated with plant extracts showed significant increase (P<0.05) in body weight and significant (P<0.05) reduction in blood glucose level when compared to diabetic control animals. Significant increase (< 0.05) was observed in the serum bilirubin, alanine transaminase (ALT), aspartate transaminase (AST), alkaline phosphatase (ALP), urea and creatinine levels of diabetic control rat group. The serum levels of these liver and kidney-related parameters of diabetic rats treated with plant extract were significantly lower when compared to diabetic control rat group (p < 0.05). Photomicrographs of liver and kidney microsections from diabetic rats treated with these plant extracts showed amelioration in the hepato-renal histoarchitectures. It was concluded that the C. colocynthis and M. charantia methanol extracts are antidiabetic and hepato-renal protective in STZ induced diabetic male rats. Treatment of the diabetic rats with C. colocynthis + M. charantia mixed extract is more effective in the amelioration of diabetes and hepato-renal injuries in STZ induced diabetic male rats.


Os efeitos protetores antidiabéticos e hepatorrenais dos extratos etanólicos de Citrullus colocynthis e Momordica charantia foram investigados em ratos albinos machos diabéticos induzidos por estreptozotocina (STZ). Ratos diabéticos foram tratados com extrato misto de C. colocynthis, M. charantia ou C. colocynthis + M. charantia na dose de 250 mg/kg de peso corporal por via oral por dia durante 21 dias. O peso corporal médio de todos os grupos de ratos diabéticos no dia 1 de tratamento (dia 10 de diabetes) foi significativamente menor do que o grupo de ratos controle normal (P < 0,05). O nível de glicose no sangue de todos os grupos de ratos diabéticos no dia 1 de tratamento (dia 10 de diabetes) foi significativamente (P < 0,05) maior (> 200 mg/dl) do que o grupo de ratos controle normal (95,5 ± 2,7). Ao final do tratamento (dia 21), os ratos diabéticos tratados com extratos vegetais apresentaram aumento significativo (P < 0,05) no peso corporal e redução significativa (P < 0,05) na glicemia quando comparados aos animais controle diabéticos. Aumento significativo (< 0,05) foi observado nos níveis séricos de bilirrubina, alanina transaminase (ALT), aspartato transaminase (AST), fosfatase alcalina (ALP), ureia e creatinina do grupo controle diabético. Os níveis séricos desses parâmetros hepáticos e renais de ratos diabéticos tratados com extrato vegetal foram significativamente menores quando comparados ao grupo controle de ratos diabéticos (p < 0,05). Fotomicrografias de microseções de fígado e rim de ratos diabéticos tratados com esses extratos vegetais mostraram melhora nas histoarquiteturas hepatorrenais. Concluiu-se que os extratos metanólicos de C. colocynthis e M. charantia são antidiabéticos e hepatorrenais protetores em ratos machos diabéticos induzidos por STZ. O tratamento de ratos diabéticos com extrato misto de C. colocynthis + M. charantia é mais eficaz na melhora do diabetes e lesões hepatorrenais em ratos machos diabéticos induzidos por STZ.

RESUMO

Natural products have long been proven very effective against various challenging diseases including cancer and bacterial infections. Galium tricorne is one of the important source of natural products, which has not been explored till date in spite of its profound ethnomedicinal prominence. The current study has been designed to explore the biological potential of G. tricorne and to extract and isolate chemical constituents from its aerial part and seeds respectively along with identification of their chemical constituents. Phytochemical screening was performed to figure out the presence of secondary metabolite in G. tricorne. Crude Methanolic extract (Gt.Crd), which was obtained from the aerial part while the fatty acids were extracted from the seeds, which were later on analyzed by GCMS. Similarly, Well Diffusion and MTT method were used for antibacterial activity and cancer cell line assay respectively. To evaluate the cytotoxic potential, brine shrimps were used. Likewise, in Gas Chromatography-Mass Spectroscopy (GC-MS) analysis a total number of 23 compounds were identified in Gt.Crd extract out of which 7 compounds were sorted out to have some sort of toxicity profile. In the same fashion, 5 fatty acids were identified in the seeds of G. tricorne. Moreover, among the fractions, chloroform fraction (Gt.Chf) exhibited greater zone of inhibition (ZOI) 20.37 mm followed by Gt.Crd 18.40 mm against S. aureus and S. pyogenes respectively. In cytotoxicity Gt.Chf was more active followed by ethyl acetate fraction (Gt.Eta) by exhibiting 88.32±0.62% (LC50=60 µg/mL) and 73.95±2.25% (LC50=80 µg/mL) respectively at 1000 µg/mL concentration of the tested sample. Gt.Chf exhibited greater cell line inhibitory activity (IC50=61 µg/mL) against HeLa cell line. Similarly, Gt.Crd displayed IC50 values of 167.84 µg/mL and 175.46 µg/mL against HeLa and NIH/3T3 cell line respectively. Based on the literature review and screenings, it may be concluded that the aerial part and seeds of G. tricorne are the rich sources of bioactive compounds. The results of the current study also authenticate the scientific background for the ethnomedicinal uses of G. tricorne.


Os produtos naturais têm se mostrado muito eficazes contra várias doenças desafiadoras, incluindo câncer e infecções bacterianas. O gálio tricorne é uma importante fonte de produtos naturais, ainda pouco explorada, apesar de sua profunda proeminência etnomedicinal. O presente estudo foi desenvolvido para explorar o potencial biológico de G. tricorne e extrair e isolar constituintes químicos de sua parte aérea e sementes, respectivamente, juntamente com a identificação de seus constituintes químicos.

Da mesma forma, os métodos Well Diffusion e MTT foram usados ​​para atividade antibacteriana e ensaio de linha de células cancerígenas, respectivamente. Para avaliar o potencial citotóxico, foram utilizadas artémias. Da mesma forma, na análise de cromatografia gasosa-espectroscopia de massa (GC-MS) um número total de 23 compostos foi identificado no extrato de Gt.Crd, dos quais 7 compostos foram selecionados para ter algum tipo de perfil de toxicidade. Da mesma forma, 5 ácidos graxos foram identificados nas sementes de G. tricorne. Além disso, entre as frações, a fração clorofórmio (Gt.Chf) apresentou maior zona de inibição (ZOI), 20,37 mm, seguida de Gt.Crd 18,40 mm contra S. aureus e S. pyogenes, respectivamente. Na citotoxicidade Gt.Chf foi mais ativo seguido pela fração acetato de etila (Gt.Eta), exibindo 88,32±0,62% (LC50=60 µg/mL) e 73,95±2,25% (LC50=80 µg/mL) respectivamente a 1000 µg/ concentração de mL da amostra testada. Gt.Chf exibiu maior atividade inibitória da linha celular (IC50 = 61 µg/mL) contra a linha celular HeLa. Da mesma forma, Gt.Crd apresentou valores de IC50 de 167,84 µg/mL e 175,46 µg/mL contra linha celular HeLa e NIH/3T3, respectivamente. Com base na revisão de literatura e triagens, pode-se concluir que a parte aérea e as sementes de G. tricorne são as ricas fontes de compostos bioativos. Os resultados do presente estudo também autenticam a base científica para os usos etnomedicinais de G. tricorne.

RESUMO

The national burden of HCV has significantly mounted over the period of last few decades placing Pakistan at the worst placement of second largest burden of HCV globally. Herein for the first time from Pakistan, we examined clinical correlation of potential biomarkers with HCV. Nation-wide study was conducted on 13,348 suspected HCV patients during 2018-2022. During pre-COVID-19 era of 2018-2019, prevalence of HCV remained 30%. During 2018, among HCV positive patients, 91% of ALT, 63% of AST, 67% of GGT, 28% of Bili T, 62% of HB, 15% of HBA1C, 25% of CREAT, 15% of PT, 15% of aPTT and 64% of AFP were abnormal. During 2019, among HCV infected 74.47% of ALT, 63.54% of AST, 70.24% of GGT, 24.71% of Bili T, 8.77% of HB and 75% of AFP were raised. CT/CAT scan revealed 4.65% liver complications (mild 13.04%, moderate 30.43% and severe 56.52%). During 2020, HCV prevalence remained 25%. 65.17% of ALT, 64.20% of AST, 68.75% of GGT, 31.25% of Bili T, 20.97% of HB, 4.65% of CREAT and 73.68% of AFP levels were raised. CAT analysis revealed liver complications among 4.41% (14.81% mild, 40.74% moderate, and 44.44% sever). 85.71% of participants diabetes was out of control. During 2021, HCV prevalence remained 27.1%. ALT (73.86%), AST (50.6%), GGT (67.95%), Bili T (28.21%), HB (20%), CREAT (5.8%) and AFP (82.14%) levels were abnormal. During 2022, the levels of ALT (56.06%), AST (56.36%), GGT (56.6%), Bili T (19.23%), HB (43.48%), HBA1C (14.81), CREAT (18.92%), AFP (93.75%) were abnormal. CAT analysis revealed 7.46% liver complications (25% mild, 30.36% moderate, and 42.86% sever). During 2021-2022, 83.33% of subject's diabetes was not controlled.


A carga nacional de HCV aumentou significativamente ao longo das últimas décadas, colocando o Paquistão na pior colocação da segunda maior carga de HCV globalmente. Pela primeira vez no Paquistão, examinamos a correlação clínica de potenciais biomarcadores com HCV. Um estudo nacional foi realizado com 13.348 pacientes suspeitos de HCV de 2018 a 2022. Durante a era pré-COVID-19 de 2018 a 2019, a prevalência do HCV permaneceu em 30%. Durante 2018, entre pacientes positivos para HCV, 91% de ALT, 63% de AST, 67% de GGT, 28% de Bili T, 62% de HB, 15% de HBA1C, 25% de CREAT, 15% de PT, 15% de aPTT e 64% de AFP eram anormais. Durante 2019, entre os infectados pelo HCV, 74,47% de ALT, 63,54% de AST, 70,24% de GGT, 24,71% de Bili T, 8,77% de HB e 75% de AFP foram elevados. A TC/TAC revelou 4,65% de complicações hepáticas (leve 13,04%, moderada 30,43% e grave 56,52%). Durante 2020, a prevalência do HCV permaneceu em 25%. 65,17% de ALT, 64,20% de AST, 68,75% de GGT, 31,25% de Bili T, 20,97% de HB, 4,65% de CREAT e 73,68% de AFP estavam elevados. A análise de TAC revelou complicações hepáticas em 4,41% (14,81% leves, 40,74% moderadas e 44,44% graves). 85,71% dos participantes o diabetes estava fora de controle. Durante 2021, a prevalência de HCV permaneceu em 27,1%. Os níveis de ALT (73,86%), AST (50,6%), GGT (67,95%), Bili T (28,21%), HB (20%), CREAT (5,8%) e AFP (82,14%) estavam anormais. Durante 2022, os níveis de ALT (56,06%), AST (56,36%), GGT (56,6%), Bili T (19,23%), HB (43,48%), HBA1C (14,81), CREAT (18,92%), AFP (93,75%) eram anormais. A análise de TAC revelou 7,46% de complicações hepáticas (25% leves, 30,36% moderadas e 42,86% severas). Durante 2021 e 2022, 83,33% do diabetes do sujeito não foi controlado.

RESUMO

The national burden of HCV has significantly mounted over the period of last few decades placing Pakistan at the worst placement of second largest burden of HCV globally. Herein for the first time from Pakistan, we examined clinical correlation of potential biomarkers with HCV. Nation-wide study was conducted on 13,348 suspected HCV patients during 2018-2022. During pre-COVID-19 era of 2018-2019, prevalence of HCV remained 30%. During 2018, among HCV positive patients, 91% of ALT, 63% of AST, 67% of GGT, 28% of Bili T, 62% of HB, 15% of HBA1C, 25% of CREAT, 15% of PT, 15% of aPTT and 64% of AFP were abnormal. During 2019, among HCV infected 74.47% of ALT, 63.54% of AST, 70.24% of GGT, 24.71% of Bili T, 8.77% of HB and 75% of AFP were raised. CT/CAT scan revealed 4.65% liver complications (mild 13.04%, moderate 30.43% and severe 56.52%). During 2020, HCV prevalence remained 25%. 65.17% of ALT, 64.20% of AST, 68.75% of GGT, 31.25% of Bili T, 20.97% of HB, 4.65% of CREAT and 73.68% of AFP levels were raised. CAT analysis revealed liver complications among 4.41% (14.81% mild, 40.74% moderate, and 44.44% sever). 85.71% of participants diabetes was out of control. During 2021, HCV prevalence remained 27.1%. ALT (73.86%), AST (50.6%), GGT (67.95%), Bili T (28.21%), HB (20%), CREAT (5.8%) and AFP (82.14%) levels were abnormal. During 2022, the levels of ALT (56.06%), AST (56.36%), GGT (56.6%), Bili T (19.23%), HB (43.48%), HBA1C (14.81), CREAT (18.92%), AFP (93.75%) were abnormal. CAT analysis revealed 7.46% liver complications (25% mild, 30.36% moderate, and 42.86% sever). During 2021-2022, 83.33% of subject's diabetes was not controlled.
