A survey of the quality of salt cured fish produced in the Kanyakumari Disrict [i.e. District], Madras State

A survey of the quality of salt cured fish in Kanyakumari District, Madras State was done during the years 1963 and 1964 to obtain necessary basic information to formulate quality standards for these products which are gaining importance in the export trade. 155 trade samples of sun-dried, dry-salted, wet-cured and pit-cured fishery products were examined for their chemical quality and organoleptic characteristics. 26.5% of the sun-dried products, 25% of the wet cured fish, 55.21% of the dried salted products and none of the pit cured samples were found to be good in quality. The sun dried products were generally found to have heavy admixture of sand and were inadequately dried. The chief defects in the salt cured fish products were found to be the use of spoiled fish, imperfect cleaning and washing, use of impure salt, inadequate salting, curing and drying, and unhygienic conditions in all stages. Quality standards must be formulated for each variety of salt cured fish product and adequate measures taken to rectify the defects and enforce the quality standards

Cardiac Risk Factors Predicting 30/90 Day Readmission Rates in Lumbar Decompression Surgeries

Preoperative cardiopulmonary disease is known to be a risk factor for perioperative complications in deformity surgery and lumbar fusion procedures, however there is a lack of literature evaluating cardiac risk factors and their influence on readmission rates following lumbar decompression surgery. We want to determine whether preoperative cardiac risk factors influenced the 30 and 90-day readmission rates in patients undergoing lumbar decompression surgery. Patient charts from Rothman Institute between were reviewed for history of preoperative cardiac risk factors such as coronary artery disease, congestive heart failure, myocardial infarction, stroke, cardiac catheterization, stent placement, coronary artery bypass graft, aspirin and/or clopidogrel use. Binary logistic regression was used to determine whether or not these risk factors predicted 30-day and 90-day readmissions for patients undergoing lumbar decompression surgery. Overall, the total number of 30-day readmissions was 33 (3.55%) and the number of 90-day readmissions was 46 (4.95%). No cardiac risk factor was found to be a significant predictor of 30-day readmission rates. Use of aspirin, 81 mg, was found to negatively predict readmission rate at 90 days (OR = 0.192 [0.042, 0.881], p = 0.034). Cardiac risk factors are known to increase surgical morbidity. The results of this study show that patients taking aspirin 81 mg preoperatively exhibited significantly lower odds of undergoing an unplanned readmission at 90 days after a lumbar decompression procedure. No significant risk factors for 30-day readmissions were found. Taking aspirin may confer a protective benefit perioperatively in a high-risk population

Integrating ethics, health policy and health systems in low and middle income countries : case studies from Malaysia and Pakistan.

Scientific progress is a significant basis for change in public-health policy and practice, but the field also invests in value-laden concepts and responds daily to sociopolitical, cultural and evaluative concerns. The concepts that drive much of public-health practice are shaped by the collective and individual mores that define social systems. This paper seeks to describe the ethics processes in play when public-health mechanisms are established in low- and middle-income countries, by focusing on two cases where ethics played a crucial role in producing positive institutional change in public-health policy. First, we introduce an overview of the relationship between ethics and public health; second, we provide a conceptual framework for the ethical analysis of health system events, noting how this approach might enhance the power of existing frameworks; and third, we demonstrate the interplay of these frameworks through the analysis of a programme to enhance road safety in Malaysia and an initiative to establish a national ethics committee in Pakistan. We conclude that, while ethics are gradually being integrated into public-health policy decisions in many developing health systems, ethical analysis is often implicit and undervalued. This paper highlights the need to analyse public-health decision-making from an ethical perspective

Automatic Road Network Recognition and Extraction for Urban Planning

The uses of road map in daily activities are numerous but it is a hassle to construct and update a road map whenever there are changes. In Universiti Malaysia Sarawak, research on Automatic Road Extraction (ARE) was explored to solve the difficulties in updating road map. The research started with using Satellite Image (SI), or in short, the ARE-SI project. A Hybrid Simple Colour Space Segmentation & Edge Detection (Hybrid SCSS-EDGE) algorithm was developed to extract roads automatically from satellite-taken images. In order to extract the road network accurately, the satellite image must be analyzed prior to the extraction process. The characteristics of these elements are analyzed and consequently the relationships among them are determined. In this study, the road regions are extracted based on colour space elements and edge details of roads. Besides, edge detection method is applied to further filter out the non-road regions. The extracted road regions are validated by using a segmentation method. These results are valuable for building road map and detecting the changes of the existing road database. The proposed Hybrid Simple Colour Space Segmentation and Edge Detection (Hybrid SCSS-EDGE) algorithm can perform the tasks fully automatic, where the user only needs to input a high-resolution satellite image and wait for the result. Moreover, this system can work on complex road network and generate the extraction result in seconds

Association between statins and the risk of suicide attempt, depression, anxiety, and seizure: A population-based, self-controlled case series study

Background: Risk of suicide attempt, depression, anxiety and seizure and the association with statins is an ongoing debate. We aim to investigate the association between statins and the above neuropsychological outcomes, in specific pre- and post-exposure time windows./ Methods: We identified patients aged 40–75 years old who were dispensed a statin between January 1, 2003 and December 31, 2012 from the Hong Kong Clinical Data Analysis & Reporting System (CDARS), an electronic medical records database. Patients with new onset of suicide attempt, depression, anxiety and seizure were derived from the original dataset separately, in a self-controlled case series study design. A non-parametric spline-based self-controlled case series model was built to measure continuous changes of risk./ Results: We identified 396,614 statin users. The risk of each outcome was elevated prior to statin initiation with incidence rate ratios of 1.38 (95 % CI, 1.09–1.74) for suicide attempt, 1.29 (95 % CI, 1.15–1.45) for depression, 1.35 (95 % CI, 1.19–1.53) for anxiety, and 1.45 (95 % CI, 1.21–1.73) for seizure. The incidence rate ratios remained elevated after the initiation of statins during the first 90 and 91–365 days after statin prescription and decreased to the baseline level after 1 year of continuous prescription./ Limitations: CDARS includes prescription data but not adherence data, which could lead to misclassification of exposure periods./ Conclusions: Our study does not support a direct association between statin use and suicide attempt, depression, anxiety and seizure, whose risks could be explained by cardiovascular events, for which statins were prescribed

Renormalization of the Lattice HQET Isgur-Wise Function

We compute the perturbative renormalization factors required to match to the continuum Isgur-Wise function, calculated using lattice Heavy Quark Effective Theory. The velocity, mass, wavefunction and current renormalizations are calculated for both the forward difference and backward difference actions for a variety of velocities. Subtleties are clarified regarding tadpole improvement, regulating divergences, and variations of techniques used in these renormalizations.Comment: 28 pages, 0 figures, LaTeX.

Exact Hypersurface-Homogeneous Solutions in Cosmology and Astrophysics

A framework is introduced which explains the existence and similarities of most exact solutions of the Einstein equations with a wide range of sources for the class of hypersurface-homogeneous spacetimes which admit a Hamiltonian formulation. This class includes the spatially homogeneous cosmological models and the astrophysically interesting static spherically symmetric models as well as the stationary cylindrically symmetric models. The framework involves methods for finding and exploiting hidden symmetries and invariant submanifolds of the Hamiltonian formulation of the field equations. It unifies, simplifies and extends most known work on hypersurface-homogeneous exact solutions. It is shown that the same framework is also relevant to gravitational theories with a similar structure, like Brans-Dicke or higher-dimensional theories.Comment: 41 pages, REVTEX/LaTeX 2.09 file (don't use LaTeX2e !!!)
