Industrial fisheries off Saurashtra coast based on exploratory survey during 1985-'88

In Saurashtra waters, where fishery resource is currently being well exploited by private sector, exploratory survey programmes are being conducted by Government of India. The analysis, based on 4 year survey (1985-'88), with a view to provide information and to extend our knowledge about the spatial and seasonal distribution of various industrially important fishes along the Saurashtra coast. Ribbon fish and sciaenids which constituted the bulk of the catch together formed more than 60% of the total catch and catch rate were 14.7 and 14.5 kg/hr respectively. Area-wise analysis of data revealed that maximum effort was expended in 21° 69 0 and the effort was very low in 21° 70° and 23° 68° Depth wise analysis revealed that the maximum catch rate of ribbon fish and other sciaenids was obtained at 21-30 m depth. The catch rate of elasmobranch, carangid and Lactarius lactarius was maximum at 41-50 m, cat fish, pomfret and perch at 51-60 m and carangid and cephalopod at 61-70 m depth

Economic evaluation of implementing a rapid point-of-care screening test for the identification of hepatitis C virus under National Viral Hepatitis Control Programme in Tamil Nadu, South India

Introduction: Viral hepatitis is a crucial public health problem in India. Hepatitis C virus (HCV) elimination is a national priority and a key strategy has been adopted to strengthen the HCV diagnostics services to ensure early and accurate diagnosis. Methods: To conduct an economic evaluation of implementing a rapid point-of-care screening test for the identification of HCV among the selected key population under the National Viral Hepatitis Control Programme in Tamil Nadu, South India. Economic evaluation of a point-of-care screening test for HCV diagnosis among the key population attending the primary health care centers. A combination of decision tree and Markov model was developed to estimate cost-effectiveness of point-of-care screening test for HCV diagnosis at the primary health care centers. Total costs, quality-adjusted life years (QALYs) of the intervention and comparator, and incremental cost-effectiveness ratio (ICER) were calculated. The model parameter uncertainties which would influence the cost-effectiveness outcome has been evaluated by one-way sensitivity analysis and probabilistic sensitivity analysis. Results: When compared to the tertiary level diagnostic strategy for HCV, the point-of-care screening for selected key population at primary health care level results in a gain of 57 undiscounted QALYs and 38 discounted QALYs, four undiscounted life years and two discounted life years. The negative ICER of the new strategy indicates that it is less expensive and more effective compared with the current HCV diagnosis strategy. Conclusions: The proposed strategy for HCV diagnosis in the selected key population in Tamil Nadu is dominant and cost-saving compared to the current strategy

Prediction of micro-spun yarn lea CSP using artificial neural networks

372-377<span style="font-size: 14.0pt;mso-bidi-font-size:8.0pt;font-family:" times="" new="" roman","serif""="">A back-propagation artificial neural network has been used to develop a model relating to cotton fibre properties and micro-spun yarn lea CSP. Fibre properties such as span length , bundle strength, fineness, breaking elongation, uniformity ratio and percentage of mature fibres have been studied. It is observed that a neural network architecture having five hidden neurons in one hidden layer and an epoch size of 12 gives better prediction. The predictions are more accurate than those obtained from regression models. The mean absolute error of neural network model is found to be 60% lower than those of the regression models. </span

Long-term outcome after sequential resections of liver and lung metastases from colorectal carcinoma

AbstractBackgroundSurgical resection of colorectal liver metastases (CLM) is an established form of treatment. Limited data exists on the value of sequential hepatic and pulmonary metastasectomy. We analysed patients who underwent sequential liver and lung resections for CLM.MethodsA total of 910 patients who underwent liver resection for CLM between January 2000 and December 2007, were analysed to identify patients with resectable pulmonary metastases (n= 43; 4.7%). Patient demographics, overall survival and survival difference between synchronous and metachronous pulmonary metastasectomy groups were compared. In addition, outcomes in the ‘liver and lung resection’ group were compared with a matched group of ‘liver resection only’ patients (matched for age, primary disease stage, interval to liver resection and liver disease stage).ResultsForty-three patients (median age 62, range 43–83 years, 22 males) underwent sequential liver and lung resection. A total of 36 patients underwent major hepatic resections, 18 patients had bilobar disease and the median number of liver lesions resected was 3 (range 1–5 lesions). Ten patients had synchronous liver and lung metastases. The median interval between liver and lung metastasectomy was 25 months (range 2–88 months). A total of two patients underwent major lobectomies, three patients had bilateral disease and the median number of lung lesions resected was one (range 1–3). The 1-, 3- and 5-year overall survival rates after first metastasectomy were 100%, 87.1% and 53.9%, respectively, with a median survival of 42 months.PatientsUndergoing metachronous pulmonary metastasectomy had better 1-, 3- and 5-year survival rates than those with synchronous disease (100%, 88.9% and 60.9% vs. 100%, 75% and 0%, respectively; P= 0.02, log rank test). There was no significant survival difference between the ‘liver and lung resection’ and the ‘liver resection only’ groups.ConclusionSequential liver and lung resection for CLM is associated with good long-term survival in selected patients, except in those presenting with synchronous lung and liver metastases
