Canna indica-chitin-alginate composite beads for the treatment of textile dye effluent containing Rose Bengal dye

Aim: To study the adsorption of Rose Bengal dye used in textile industries by Canna indica-chitin-alginate beads. Methodology: C. indica-chitin-alginate composite beads were prepared using root tubers of Canna indica, chitin from shrimp shells and sodium alginate. Batch adsorption of Rose Bengal dye was carried out with optimized parameters like pH, contact time, adsorbent dosage and dye concentrations. Characterization studies like SEM, FTIR and TGA and reusability of composite beads were also studied. Results: The maximum adsorption of 97.9% was obtained at pH 6, 80 min contact time with the optimized ratio of 1:1:0.05 C. indica-chitin-alginate towards 100 mg l-1 dye concentration. The SEM analysis showed a porous surface morphology whereas FTIR results exhibited the functional groups of Rose Bengal dye and composite beads, proving successful adsorption. Thermogravimetric analysis revealed that the composite beads could withstand a maximum temperature of 300oC. Interpretation: It is inferred from the study that a biosorbent prepared from a commonly available plant and shells of shrimp, which is considered as a waste, can be effectively used in the adsorption of harmful textile dyes from the effluent in an eco-friendly and cost-effective way.

What rural doctors want: a qualitative study in Chhattisgarh state

The importance of addressing concerns of rural health worker welfare in order to improve their performance and retention is widely acknowledged; yet there is little empirical research on the needs of rural health professionals. We report findings from a qualitative research study in rural Chhattisgarh, involving indepth interviews with 37 practitioners and data analysis using the “framework” approach. Participants’ expressions of their needs encompassed a range of reforms and improvements, including better salaries and job security, more rational posting and promotion procedures, and facility improvements. Opportunities for need-based skills training and better housing also emerged as key needs, as did better schools, assurance of personal security, and recognition and appreciation of their services by the administration. Increased investment in rural infrastructure and training, graded packages of benefits for rural doctors, and governance reforms to improve the internal accountability of government health services emerge as recommendations from the study.

Questions of ethics in public health policy.

Most discussions in public health policy revolve aroundthe setting of priorities and issues of technological choice and programme design in achieving these prioritised outcomes. Priority setting and choice of strategy are political choices. They are negotiations between what the public perceives, what public health experts pronounce, and the perception of interest groups – or stakeholders, as they are more often referred to – of the impact of any particular choice. Here, I set out to examine the choices of priorities and strategies using an ethics lens.

Comments on the National Health Research Policy.

Health research is an important component of the process for reaching the goal of Health for All expressed in the Alma Ata Declaration. Today, 33 years after the Declaration, the goal is best expressed in terms of health systems that can provide universal access to comprehensive healthcare as well as action on social determinants of health to reduce the burden of disease and promote good health

National Rural Health Mission--hopes and fears. Concerns about targeted sterilisation, retreat of the state and privatisation.

The National Rural Health Mission (NRHM), launched by the present government as part of its honouring the Common Minimum Programme (CMP) commitment, had its content shaped by an active process of dialogue between many stakeholders. This article traces the contours of the discussions on three key concerns of civil society that influenced their contributions to the shaping of the National Rural Health Mission agenda. These three concerns were promotion of targeted sterilisation, a retreat of the state from its commitments to the health sector and that the NRHM agenda would lead to privatisation of public health facilities. Whereas fears on targeted sterilisation and retreat of the state may be unrealistic, there is a thrust to increased involvement of the private sector, which needs to be understood in its entirety. There is need for continued engagement byequity concerned public health professionals and health activists at all levels of implementation and not merely community monitoring to influence and shape the National Rural Health Mission in a pro-poor direction.

Unexpected presentations--four cases of lead poisoning.

OBJECTIVE: To describe the clinical presentation and response to treatment of four patients who presented with abdominal pain and were diagnosed to have lead poisoning. METHODS: After ruling out the more obvious causes of abdominal pain by barium studies, gastrointestinal endoscopies, and biochemical studies, blood lead levels were estimated by atomic absorption spectrophotometry. The patients were treated with oral d-penicillamine. RESULTS: The four patients had blood lead levels from 79 microg/dL to 365 microg/dL. All four of them showed marked improvement in their clinical condition and lowering of blood lead levels on follow up. CONCLUSIONS: Clinicians need to develop a high index of suspicion of lead poisoning as a possible cause of unexplained abdominal pain or altered sensorium, especially against a background of environmental lead contamination in India.

Streptococcus agalactiae endocarditis.

Streptococcus agalactiae (S. agalactiae) is a rare cause of infective endocarditis, which is associated with a high mortality rate. Endocarditis in adults is generally related to immunocompromised states. We hereby report the case of a 35 year old man who presented with fever and delirium in whom aortic valve endocarditis due to S. agalactiae was detected. Though most patients with S. agalactiae endocarditis need surgical intervention along with antibiotics, our patient improved with medical therapy alone.

Scorpion envenomation as a risk factor for development of dilated cardiomyopathy.

OBJECTIVES: Though scorpion envenomation is known to lead to acute myocarditis and a reversible decrease in left ventricular function, it has not been implicated as an etiological factor in idiopathic dilated cardiomyopathy. We studied the association of idiopathic dilated cardiomyopathy with a history of scorpion sting as well as with socio-economic status, history of smoking and alcoholism, rural habitation, and history of snake bites. METHODS: Consecutive cases of idiopathic dilated cardiomyopathy were recruited for this study: The association with putative risk factors was studied using a case-control study design with two sets of controls. One set of controls were age and sex matched inpatients selected at random, the other set of controls were spouse, or if not available, a close relative, ordinarily resident with the patient. RESULTS: On analysis, none of the factors except scorpion envenomation had a significant association. A past history of scorpion envenomation had an adjusted odds ratio of 8.01 (3.55-18.06) when compared to one set of controls and an odds ratio of 8.33 (6.55-10.59) when compared to the second group of controls. CONCLUSIONS: Our study indicates that a history of scorpion envenomation acts as a risk factor for the subsequent development of idiopathic dilated cardiomyopathy. Despite an apparently complete recovery from a scorpion sting, many patients probably retain sub-clinical deficits that predispose to the development of cardiomyopathy later in life, when other factors get added on. The known association of cardiomyopathy with catecholamine excess in experimental situations in animal studies, and in other disease states in humans, supports this hypothesis.
