On the recent Introduction of outboard engines along the Coromandal coast

Introduction of outboard engines along the Coromandal coast and Pondicherry were studied. A total number of 232 outboard engines have been introduced at 16 fish landing centres in the South Arcot District. The outboard engines are fitted exclusively to catamarans with a length range of 8-10 m operating mainly gill nets, Pannu valai and Mani valai and the encircling bag-net, Eda valai

A bibliography of parasites and diseases of marine and freshwater fishes of India

With the increasing demand for fish as human food, aquaculture both in freshwater and salt water is rapidly developing over the world. In the developing countries, fishes are being raised as food. In many countries fish farming is a very important economic activity. The most recent branch, mariculture, has shown advances in raising fishes in brackish, estuarine and bay waters, in which marine, anadromous and catadromous fishes have successfully been grown and maintained

Impact of opioid-free analgesia on pain severity and patient satisfaction after discharge from surgery: multispecialty, prospective cohort study in 25 countries

Background: Balancing opioid stewardship and the need for adequate analgesia following discharge after surgery is challenging. This study aimed to compare the outcomes for patients discharged with opioid versus opioid-free analgesia after common surgical procedures.Methods: This international, multicentre, prospective cohort study collected data from patients undergoing common acute and elective general surgical, urological, gynaecological, and orthopaedic procedures. The primary outcomes were patient-reported time in severe pain measured on a numerical analogue scale from 0 to 100% and patient-reported satisfaction with pain relief during the first week following discharge. Data were collected by in-hospital chart review and patient telephone interview 1 week after discharge.Results: The study recruited 4273 patients from 144 centres in 25 countries; 1311 patients (30.7%) were prescribed opioid analgesia at discharge. Patients reported being in severe pain for 10 (i.q.r. 1-30)% of the first week after discharge and rated satisfaction with analgesia as 90 (i.q.r. 80-100) of 100. After adjustment for confounders, opioid analgesia on discharge was independently associated with increased pain severity (risk ratio 1.52, 95% c.i. 1.31 to 1.76; P < 0.001) and re-presentation to healthcare providers owing to side-effects of medication (OR 2.38, 95% c.i. 1.36 to 4.17; P = 0.004), but not with satisfaction with analgesia (beta coefficient 0.92, 95% c.i. -1.52 to 3.36; P = 0.468) compared with opioid-free analgesia. Although opioid prescribing varied greatly between high-income and low- and middle-income countries, patient-reported outcomes did not.Conclusion: Opioid analgesia prescription on surgical discharge is associated with a higher risk of re-presentation owing to side-effects of medication and increased patient-reported pain, but not with changes in patient-reported satisfaction. Opioid-free discharge analgesia should be adopted routinely

Development of an immunological staging system to prognosticate disease course in malignant cervical neoplasia

A multiparameter analysis of immune function was done on patients with squamous cell carcinoma of the uterine cervix to look for any variable(s) that could be correlated with the clinical stage of the disease. Five immunological variables, viz., CD4+ lymphocytes, CD4/CD8 ratio, natural killer cells, concanavalin A-induced suppressor index, and circulating immune complexes, were found to consistently vary with tumor load. When these variables were subjected to a multiple regression and multivariate analysis, an equation for a diagnostic index curve was derived. Application of this equation led to an immunological staging system which could be used as an excellent prognostic indicator. The immunological staging system showed that patients classified into a particular clinical (FIGO) stage behaved in a heterogeneous way immunologically and that patients developing recurrent disease could easily be identified from those remaining disease free, even before treatment. Subsequent follow-up of these patients further confirmed this observation, with the recurrent disease group easily identifiable. These results point out the immense potential of such a staging system and the importance of immunological evaluation in the preliminary management of patients with malignant cervical neoplasia

Chemical characteristics of coastal rainwater from Puducherry to Neithavasal, Southeastern coast of India

The chemistry of the rainwater indirectly reflects the composition of the ions in the atmosphere. The study of the rainwater gains its own importance as it forms the basis for the agricultural, domestic and drinking water. Twelve rainwater samples were collected along the southeastern coast of India during southwest monsoon. The samples were analyzed for the major anions (Cl−, SO4 2−, PO4 3− and HCO3 −) and cations (Na+, K+, Ca2+ and Mg2+). The majority of the samples reflect acidic pH. The general dominance of the cations is in the order of Na+ > Ca2+ > K+ > Mg2+ and that of anions is HCO3 − > Cl− > SO4 2− > PO4 3−. The water is classified as calcium bicarbonate to sodium bicarbonate type. The decrease of pH value also increases the pCO2. In order to study the impact of acidic and alkaline species on rainwater, correlation coefficients were determined for establishing the relationship between different ions. Good correlation was established between cations, and sulfate has no correlation with other ions and pH. Factor analysis reveals that land use pattern, marine source and methanogenesis from the tidal influenced mangroves play a major role in determining the rainwater chemistry of the region
