RESUMEN

AIMS: This review explores the mechanisms, diagnostic approaches, and management strategies for COVID-19-induced liver injury, with a focus on its impact on patients with pre-existing liver conditions, liver cancer, and those undergoing liver transplantation. MATERIALS AND METHODS: A comprehensive literature review included studies on clinical manifestations of liver injury due to COVID-19. Key areas examined were direct viral effects, drug-induced liver injury, cytokine storms, and impacts on individuals with chronic liver diseases, liver transplants, and the role of vaccination. Data were collected from clinical trials, observational studies, case reports, and review literature. KEY FINDINGS: COVID-19 can cause a spectrum of liver injuries, from mild enzyme elevations to severe hepatic dysfunction. Injury mechanisms include direct viral invasion, immune response alterations, drug toxicity, and hypoxia-reperfusion injury. Patients with chronic liver conditions (such as alcohol-related liver disease, nonalcoholic fatty liver disease, cirrhosis, and hepatocellular carcinoma) face increased risks of severe outcomes. The pandemic has worsened pre-existing liver conditions, disrupted cancer treatments, and complicated liver transplantation. Vaccination remains crucial for reducing severe disease, particularly in chronic liver patients and transplant recipients. Telemedicine has been beneficial in managing patients and reducing cross-infection risks. SIGNIFICANCE: This review discusses the importance of improved diagnostic methods and management strategies for liver injury caused by COVID-19. It emphasizes the need for close monitoring and customized treatment for high-risk groups, advocating for future research to explore long-term effects, novel therapies, and evidence-based approaches to improve liver health during and after the pandemic.

RESUMEN

This study comprehensively explores the complexities of rheumatoid arthritis during pregnancy and its impact on offspring. Through an extensive review of existing literature, we investigate maternal and fetal risks, including adverse pregnancy outcomes and developmental issues in offspring. Utilizing reputable databases such as PubMed, Google Scholar, and Science Direct, we meticulously examined studies exploring the connection between rheumatoid arthritis and pregnancy complications, with a focus on outcomes for offspring. We excluded studies lacking sufficient data or peer review. Synthesizing findings from selected studies, we identified common themes and patterns, presenting results in a clear, organized manner. Our examination reveals a heightened likelihood of preterm birth and preeclampsia among pregnant individuals with rheumatoid arthritis, often correlated with disease activity. Furthermore, we highlight the impact on fetal and neonatal outcomes, such as low birth weight, underscoring the importance of meticulous disease management throughout pregnancy. Balancing the necessity of disease-modifying agents with potential risks, and consideration of medication safety is paramount. A multidisciplinary approach involving rheumatologists and obstetricians is crucial for optimizing outcomes. In conclusion, this synthesis underscores the nuanced challenges of rheumatoid arthritis in pregnancy. A comprehensive understanding and personalized, multidisciplinary approach to an organization is essential for informed decision-making in clinical practice. Our review contributes to ongoing discourse, providing insights for enhanced patient care and guiding future research endeavors.

RESUMEN

Identifying the new tree crop combinations plays an important function in transforming the low input agriculture into land units with high economic returns, increasing carbon (C) sink and nutrients storage capacity, and acting as a panacea to achieve Sustainability Development Goals (SDGs). The present study aims to evaluate various tree-crop combinations for (i) biomass production, (ii) carbon accumulation, and (iii) soil nutrient enrichment of traditional and commercially evolved eight agroforestry systems (AFSs), including agri-silvi-horticulture system, agri-silviculture system, silvi-pasture, fruit tree, fodder tree, bamboo, melia and poplar based AFSs with sole cropping system in the mid-hill zone of the north-western Himalaya. The results demonstrated that poplar based AFS accumulated a higher amount of biomass (130.87 Mg ha-1) and carbon (65.44 Mg ha-1) closely followed by melia-based AFS. The C stored in leaf litter was higher (0.66 Mg ha-1) in poplar-based AFS, however, soil C stock was maximum (114.69 Mg ha-1) under bamboo-based AFS. Overall, the Melia based AFS exhibited a higher rate of carbon dioxide mitigation (19.30 Mg ha-1 yr-1) and C-sequestration (5.26 Mg ha-1 yr-1) than other studied AFSs. Moreover, soil macro-nutrients (available N, P, K, S and Ca) were maximum under bamboo-based AFS, on the other hand, the fruit-based AFS had the higher concentrations of micro-nutrients i.e., Cu (3.05), Fe (31.10 mg g-1) and Mn (17.31 mg g-1). The soil microbial counts were higher in poplar-based AFS, whereas, the soil quality index improved significantly under bamboo based and fruit tree based AFSs. Hence, it can be concluded that the experimentally evolved AFSs represent an effective approach for boosting C-sequestration, soil fertility, regenerating the soil and sustainability of hill agriculture in the north-western Himalayas over traditional AFSs and sole cropping.

RESUMEN

OBJECTIVE: Little is known about barriers to healthcare access for two-spirit, gay, bisexual and queer (2SGBQ+) men in Manitoba. DESIGN: Data were drawn from a community-based, cross-sectional survey designed to examine health and healthcare access among 2SGBQ+ men. SETTING: Community-based cross-sectional study in Manitoba, Canada. PARTICIPANTS: Community-based sample of 368 2SGBQ+ men. OUTCOMES: Logistic regression analyses assessed the relationship between sociodemographics, healthcare discrimination, perceived healthcare providers' 2SGBQ+ competence/knowledge and two indicators of healthcare access (analytic outcome variables): (1) having a regular healthcare provider and (2) having had a healthcare visit in the past 12 months. RESULTS: In multivariate analyses, living in Brandon (adjusted OR (AOR)=0.08, 95% CI 0.03 to 0.22), small cities (AOR=0.20, 95% CI 0.04 to 0.98) and smaller towns (AOR=0.26, 95% CI 0.08 o 0.81) in Manitoba (compared with living in Winnipeg), as well as having a healthcare provider with poor (AOR=0.19, 95% CI 0.04 to 0.90) or very poor competence/knowledge (AOR=0.03, 95% CI 0.03 to 0.25) of 2SGBQ+ men's issues (compared with very good competence) was associated with lower odds of having a regular healthcare provider. Living in Brandon (AOR=0.05, 95% CI 0.02 to 0.17) and smaller towns (AOR=0.25, 95% CI 0.67 to 0.90) in Manitoba (compared with living in Winnipeg) was associated with lower odds of having a healthcare visit in the past 12 months, while identifying as a gay man compared with bisexual (AOR=12.57, 95% CI 1.88 to 83.97) was associated with higher odds of having a healthcare visit in the past 12 months. CONCLUSIONS: These findings underscore the importance of reducing the gap between the healthcare access of rural and urban 2SGBQ+ men, improving healthcare providers' cultural competence and addressing their lack of knowledge of 2SGBQ+ men's issues.

RESUMEN

Rheumatoid arthritis (RA) is an autoimmune systemic inflammatory disorder that is mostly characterised by progressive symmetrical joint destruction, particularly in the wrist and fingers, while it may also affect additional joints and several organs, such as the skin, heart, blood vessels, and lungs. It is identified by raised anti-rheumatoid factor and anti-cyclic citrullinated peptide antibodies. The chemical mediators involved in the activity of RA are IL-1ß, TNF-α, and IL-6. Pregnancy exerts a positive effect on RA that helps to modulate the disease condition. Different hypotheses are recommended to explain the ameliorating effect of pregnancy in RA. RA cannot be completely cured. The treatment goal is the attrition of pain and inflammation and the further progression of the disease. Long-term management of RA is carried out using disease-modifying antirheumatic drugs (DMARDs). Therapy of acute flares can be done with Non-steroidal anti-inflammatory drugs (NSAIDs) accompanied by ad interim usage of glucocorticoids. Biologic response modifiers are also available; they act by abolishing the activity of T- cells. However, it is necessary to select the correct treatment regimen when it comes to the management of RA in pregnancy.

RESUMEN

OBJECTIVES: The study was carried out with the aim to find out the frequency of Glucose 6 phosphate dehydrogenase (G6PD) deficiency among the patients attending the hospital and to rationalize the qualitative methemoglobin reduction test in reference to the quantitative spectrophotometric assay. Timely screening of the patients for G6PD with appropriate screening method can play an important role in preventing hemolytic crisis that arises from therapeutic use of oxidative drugs like primaquine. RESULT: The frequency of G6PD deficient cases was 3% by both of the employed tests. The mean ± SD of G6PD activity in the patients under study was 15.34 ± 4.7 IU/g Hb in males and 16.01 ± 3.74 IU/g Hb in females. G6PD activity was positively associated with reticulocyte count (r = 0.289, p value = 0.004) and negatively with mean corpuscular hemoglobin concentration (r = -0.220, p-value = 0.028). The correlation of red blood corpuscular count and G6PD was statistically significant (p-value = 0.048).

RESUMEN

Functionalization of perfluoro aryl azides by bifunctional chelating agents (BFCAs) capable of forming high specific activity complexes with (99m)Tc (for gamma-imaging) and (188)Re (for radiotherapy) is described. The synthesis of multidonor BFCAs containing N(2)S(2), N(4), and N(3)S donor groups containing imidazole, pyridine, and pyrazine functionalities that may be important for tuning the pharmacokinetic parameters is also described. Functionalization of perfluoro aryl azides at various sites on BFCAs yields novel bifunctional photolabile chelating agents (BFPCAs) that are useful for covalent attachment to biomolecules. A representative Re-BFPCA 8a in a model solvent, diethylamine, proceeded to give a high yield of intermolecular NH insertion product without the decomplexation of the metal ion from 8a. All products originated from the photolysis of 8a in diethylamine are characterized by analytical techniques, and a plausible mechanism of formation of different photolytic products is suggested. The high yield of intermolecular NH insertion of Re-BFPCA 8a is extended to labeling of human serum albumin (HSA) and Fab fragments under aqueous conditions. The photolabeling technology developed here offers a new way to attach diagnostically and therapeutically useful radiotracers (e.g., (99m)Tc, (188)Re) to Fab fragments for potential noninvasive imaging and therapy of cancer.
