  • Role of Inflammatory Markers in Predicting Severity and Outcome in COVID-19 Patients Attending a Tertiary Care Institute of Tamil Nadu
    Durga Krishnan and
    Journal of Communicable Diseases, 2022
    Background:Severe acute respiratory syndrome Coronavirus 2 (SARS-COV 2) infection elicits an inflammatory response which is responsible for severe clinical manifestations, disease progression and, poor outcomes.Objectives: This study aims to assess the pattern of elevation of inflammatory markers in COVID-19 and to determine their association with clinical, radiological severity and outcome of COVID 19.Methodology: This is a retrospective single-center cross-sectional study conducted at Chettinad Hospital and Research Institute, a tertiary care Hospital in Tamil Nadu, India, encompassing a cohort of 1220 patients. The source population was all cases of COVID-19 admitted at the hospital with a confirmed diagnosis of COVID-19 using RT PCR. The data was obtained from the patient’s case sheets and laboratory investigations and from the electronic data management system. The patient’s clinical severity on admission, baseline characteristics, co-morbid illnesses, presenting complaints, vitals, and inflammatory markers like D-dimer, C-reactive protein IL-6, Serum ferritin, and Lactate dehydrogenase were collected. The data for radiological severity and outcome were coded and analysed.Results: Diabetes and hypertension were found to be the most common comorbidities in the study population; females more affected than males. Fever and cough are the most common presenting symptoms. The clinical severity of patients was found to have a significant association with radiological severity. D-dimer is having a strong correlation with disease severity and outcome at any point in time. IL-6, CRP, Serum ferritin also showed a strong correlation with outcome in COVID-19.Conclusion:Our study suggests D-dimer at any point of time in a hospitalized COVID-19 patient as a promising marker for the same. IL-6 is the next best inflammatory marker followed by CRP and Serum ferritin. LDH is the least significant one among these.
  • Assessment of threats to a Ramsar site from seafood processing operation effluents

    Waterbodies receiving effluents from seafood processing plants might experience severe eutrophication. The present study was carried out to assess the impacts of effluent discharges on water quality and phytoplankton populations in the Vembanad‐kol Wetland, located adjacent to seafood processing industries. It was conducted in the Cherthala–Aroor–Edakochi coastal belt of Vembanad Wetland, India, a region containing many processing plants. The trophic status of the lake was assessed with the Carlton trophic state index. Hypereutrophic conditions were observed more in the interconnected channels than in the main waterbody. There was a dominance of Bacillariophyceae, followed by Chlorophyceae, Cyanophyceae and Dinophyceae. Bacillariophyceae, Chlorophyceae and Cyanophyceae were comparatively higher in the interconnected channels, whereas Dinophyceae was high in the main body of the lake. There is a shift in dominance from Chlorophyceae to Cyanophyceae in the interconnected channels, especially in the southern and central portion of the lake. There was a dominance of Cyanophyceae over Chlorophyceae, especially in the interconnected channels, being a characteristic of polluted water. Nitzschia sp and Navicula sp were abundant in the class Bacillariophyceae. The dominant species in the class Dinophyceae was Ceratium sp, which is known to proliferate in nutrient‐rich waters. The dominant members of the class Chlorophyceae were Ankistrodesmus sp and Scenedesmus sp. Furthermore, Oscillatoria and Phormidium were higher in number in the class Cyanophyceae, indicating the presence of pollutants of biological origin. Waste discharges from the seafood processing industry are a major factor contributing to an alarming rate of organic pollution and subsequent eutrophication in the lake. The results of the present study highlight that further expansion of the seafood industry in the Cherthala–Aroor–Edakochi coastal belt of Vembanad Lake is not desirable.
  • Selecting a suitable diversity index for a tropical Ramsar wetland site

    Wetlands are under threat from the inflow of urban pollutants on a daily basis. The phytoplankton community is the most affected by increasing eutrophication. Biodiversity based on species richness and evenness can reflect the phytoplankton community composition, as well as describing the water pollution impacts on biotic communities. Eutrophication is a major problem in tropical wetland systems because they receive various waste discharges. Therefore, an attempt was made in this study to analyse the eutrophication status of a tropical wetland (part of the Vembanad Wetland in Cherthala‐Aroor‐Edakochi coastal belt, Kerala) that is being affected by seafood effluent discharges. Alpha indices (Shannon–Weiner Diversity Index; Simpson Index) and beta diversity (Jaccard Index and Sorensen Index) were used to identify appropriate diversity index in a eutrophic environment. Analysis of the plankton populations indicated significant variations among the wetland sampling sites, with the highest percentage of pollution indicators observed in the interconnected channels than in the main portion of the wetland. The results of this study also reveal that a dangerous level of reduction in Chlorophyceae occurred which, in turn, affects the wetland primary productivity. If this situation continues, the wetland will become dominated by fewer, more pollution‐tolerant species over time, indicating serious attention must be given to stopping the loss of diversity in the wetland. This study revealed that β diversity indices are more suitable for studying diversity in a eutrophic wetland system than α diversity indices, mainly because β diversity indices indirectly consider the pollution indicator species, whereas the Shannon Index fails to do so. This study also notes the importance of using the Simpson Index over the Shannon Index for eutrophic waterbodies.
