Comparative study of effectiveness and safety of nonsteroidal anti-inflammatory drugs in patients of knee joint osteoarthritis of knee, tertiary care hospital, Bidar, India
Background: Osteoarthritis (OA) is a joint failure and OA is the most frequent chronic joint disease causing pain and disability. Where all the structures of joints have undergone pathological changes and they are hyaline articular cartilage loss which may be focal or non-uniform, initially it will be focal then spread all over non-uniformly. Non-Steroidal Anti Inflammatory Drugs (NSAID) are the mainstay of medical management of OA. Increased in reports suggests that GIT adverse effect with old NSAID’s and cardiovascular effects with selective cyclooxygenase-2 (COX2) inhibitors had precipitated to chase for better NSAID’s with minimal adverse effects. The current study compares the clinical effectiveness and safety of newer NSAID’s, etoricoxib, lornoxicam, to diclofenac which has been standard therapy in patients of OA of the knee joint.Methods: The current study is randomized, prospective, open-label, parallel group study conducted in 120 patients with OA of the knee joint diagnosed using American College of Rheumatology criteria. After getting the informed consent, they were randomized in three groups of 40 patients each who received tablet etoricoxib 120mg BID, tablet Lornoxicam 16mg BID, tablet diclofenac 50mg TID respectively. The duration of the study is 12 weeks. Data are calculated, tabulated and analyzed using analysis of variance (ANOVA) test, and level of significance was determined by its P value.Results: After 12weeks of treatment, the severity of pain and functional indices using visual analog scale and Western Ontario and McMaster Universities Osteoarthritis score were significantly better (P <0.05) in etoricoxib group as compared to lornoxicam or diclofenac group along with a lesser rate of adverse effects.Conclusions: It is concluded that etoricoxib is more effective and tolerated NSAID than lornoxicam and diclofenac in the treatment of knee joint OA
The Geometry of PSR B0031-07
PSR B0031-07 is well known to exhibit three different modes of drifting
sub-pulses (mode A, B and C). It has recently been shown that in a
multifrequency observation, consisting of 2700 pulses, all driftmodes were
visible at low frequencies, while at 4.85 GHz only mode-A drift or non-drifting
emission was detected. This suggests that modes A and B are emitted in
sub-beams, rotating at a fixed distance from the magnetic axis, with the mode-B
sub-beams being closer to the magnetic axis than the mode-A sub-beams. Diffuse
emission between the sub-beams can account for the non-drifting emission. Using
the results of an analysis of simultaneous multifrequency observations of PSR
B0031-07, we set out to construct a geometrical model that includes emission
from both sub-beams and diffuse emission and describes the regions of the radio
emission of PSR B0031-07 at each emission frequency for driftmodes A and B.
Based on the vertical spacing between driftbands, we have determined the
driftmode of each sequence of drift. To restrict the model, we calculated
average polarisation and intensity characteristics for each driftmode and at
each frequency. The model reproduces the observed polarisation and intensity
characteristics, suggesting that diffuse emission plays an important role in
the emission properties of PSR B0031-07. The model further suggests that the
emission heights of this pulsar range from a few kilometers to a little over 10
kilometers above the pulsar surface. We also find that the relationships
between height and frequency of emission that follow from curvature radiation
and from plasma-frequency emission could not be used to reproduce the observed
frequency dependence of the width of the average intensity profiles.Comment: 15 pages, 9 figures, 8 tables, accepted for publication in A&
Small error algorithms for tropical group testing
We consider a version of the classical group testing problem motivated by PCR testing for COVID-19. In the so-called tropical group testing model, the outcome of a test is the lowest cycle threshold (Ct) level of the individuals pooled within it, rather than a simple binary indicator variable. We introduce the tropical counterparts of three classical non-adaptive algorithms (COMP, DD and SCOMP), and analyse their behaviour through both simulations and bounds on error probabilities. By comparing the results of the tropical and classical algorithms, we gain insight into the extra information provided by learning the outcomes (Ct levels) of the tests. We show that in a limiting regime the tropical COMP algorithm requires as many tests as its classical counterpart, but that for sufficiently dense problems tropical DD can recover more information with fewer tests, and can be viewed as essentially optimal in certain regimes
Women empowerment through green mussel (Perna viridis) farming : Focus on Kerala
Mussel farming is one of the best ideas for the
utilisation of natural resources as well as human
resources in a sustainable manner. It is an activity with
potential to empower women by giving them a chance to
earn additional income for their family, thereby making
them self-reliant. Thus, looking at the larger picture
mussel farming could bring about an improvement in
the socio-economic condition of families in the coastal
States of India. Additionally, it also ensures production
of healthy and protein rich food for the consumers
An overview of municipal solid waste management in Jaipur city, India - Current status, challenges and recommendations
In developing countries, urbanization and rapid population growth has resulted in a substantial increase in generation of Municipal Solid Waste (MSW). Safe collection, transportation and treatment of MSW are among the major issues for Indian cities. Poor MSW management practices have negative impact on public health, environment and climate change. India currently only treats 21% of MSW while the remainder disposed in unsanitary landfill sites with no recycling and treatment technologies. This paper reviews the existing MSW management practices, challenges and provides recommendations for improving MSW management for the city of Jaipur in Rajasthan, India.
Despite being the state capital as well as the top tourist destination in northern part of India, there is no detailed study which reviews the waste management strategies of this city along with identifying the key challenges. The study reveals that the major challenges for MSW management in Jaipur include uncontrolled landfilling, inadequate public participation as well as failings of implementation of MSW legislation and waste conversion. Recommendations for improvement include public awareness campaigns, public-private partnership, investment in lined landfills, recycling and waste to energy techniques. Optimization models and life cycle assessment tools should be employed to minimize cost and the environmental impact of MSW management. This study will provide policy makers and private sector stakeholders to develop strategies for future planning, investment and execution of improved MSW management in Indian cities
Spatial variability in sea surface temperature and wind-driven coastal upwelling along the southwest coast of India
The coastal environment along the southwest coast of India is influenced by seasonal wind-driven coastal upwelling. The trend of upwelling index (UI) and sea surface temperature (SST) along the southwest coast of India during 1988-2015 were analysed in this study. In order to understand the spatial variation in SST and UI, the entire southwest coast of India was divided into three strata viz. stratum_1 (ST_1, southern part), stratum_2 (ST_2, middle part) and stratum_3 (ST_3, northern part). Temporal analyses of these parameters were carried out for three seasons such as monsoon (June-September), post-monsoon (OctoberJanuary) and pre-monsoon (February-May). In addition to seasonal changes in upwelling, large-scale latitudinal differences in upwelling were observed during this study, which is associated with spatial differences in coastal topography. The upwelling index along stratum_3 has increased after 1995 compared to previous period. Both SST and UI exhibited spatial variation along southwest coast of India. Eventhough, UI is higher during the summer monsoon compared to other seasons, a declining trend in UI during the summer monsoon was found from
1988 to 2015
Improving resistance of austenitic stainless steel to irradiation damage
It is believed that the addition of oversized solute atoms disturbs the process of recombination,
agglomeration, and migration of point defects during irradiation process and thereby alters radiation damage,
including radiation induced segregation. In this study, austenitic stainless steel (SS) 316 samples with different
Ce content (0.00, 0.01, 0.04 and 0.09 wt% Ce) were irradiated using 4.8 MeV protons at 300°C to the total
fluence of 9.724×1017 p/cm2. Irradiated samples were characterized using double-loop electrochemical
potentiokinetic reactivation (DL-EPR) technique for the extent of RIS due to proton irradiation. It was found
that the sample with 0.04 wt% Ce content showed the lowest EPR value, as measured by DL-EPR. It was also
noticed that the slip lines were get preferentially attacked vis-à-vis grain boundaries. SS 316 Ce 0.09 wt%
sample did not have any slip-lines and attack during the DL-EPR was confined to grain boundaries and few pitlike
structures were noticed during AFM examinations
