Pattern of dyslipidaemia in human immunodeficiency virus infected patients- a study from rural tertiary care hospital in central India

Background: HIV/AIDS is a major health problem affecting the whole globe. With introduction of highly active antiretroviral therapy longevity of HIV patient have increased and they are subjected to high cardiovascular risk as age increases due to various risk factors. Of these dyslipidaemia is one of important risk factor and HIV patients have different degree of deranged lipid profile. Various studies have shown different lipid derangement in these patients but most of them were conducted in urban areas, so this study was conducted to look for lipid profile in HIV patients who are resident of rural areas. Methods: This study was conducted on 66 HIV infected or AIDS cases. Each case was subjected to history taking, through clinical examination and fasting lipid levels. Dyslipidaemia was a classified using NCEP/ATP III guideline.Results: Of total 66 cases, there were 39 male and 27 female with average age of 37 years. Hypercholesterolemia was present in 50% of patients, hypertriglyceridemia in 36.4%. LDL and VLDL were raised in 37.9% and 36.4% respectably while HDL was found below 40 mg/dl in 37.9% of the patients. S. total cholesterol, HDL and LDL was found to have positive correlation while S. TG and VLDL have no significant correlation with CD4 count.Conclusions: Present studies have shown high prevalence of dyslipidaemia in different WHO clinical stage with variable correlation with CD4 count

Prevalence of metabolic syndrome in a rural population- a cross sectional study from Western Uttar Pradesh, India

Background: Prevalence of non-communicable diseases like hypertension, diabetes mellitus and coronary artery disease is on the rise due to the change in lifestyle, unfavourable dietary habits and obesity. Metabolic syndrome is a simple tool by which we can predict the future risk of diabetes mellitus and cardiovascular disease. Studies showed that prevalence of metabolic syndrome is rising in Indian population, but majority of them were done in urban population. This study was conducted to look into the current status of the metabolic syndrome in rural population.Methods: The study was conducted among a population of 2982. Each participant was subjected to clinical examination, anthropometric measurements and necessary laboratory investigations. Metabolic syndrome was diagnosed based on modified NCEP: ATP III criteria.Results: The prevalence of metabolic syndrome was found to be 11.7% and was higher among female population (13.8%) as compared to males (9.6%). The prevalence of metabolic syndrome increased with increasing age. 28.3% of the participants over the age of 50 years had metabolic syndrome whereas it was only 0.4% below the age of 20 years. Nearly half (47.1%) of the obese individuals were suffering from metabolic syndrome implicating obesity as one of the most important risk factors in the etiopathogenesis of metabolic syndrome. The prevalence was only 1.1% among the underweight group.Conclusions: Present study has shown moderate prevalence of metabolic syndrome among the rural population of Western Uttar Pradesh, India with a more female predisposition

Prevalence of type 2 diabetes mellitus in rural population of India- a study from Western Uttar Pradesh

Background: Diabetes is a major challenge for a resource-limited country like India. Majority of the patients are diagnosed late in the course of illness with presence of complications. There is limited data on diabetes from rural India. Present study is an attempt to provide data on diabetes in rural India. The overall objective of present study was to estimate the prevalence of Type 2 diabetes mellitus in rural population above 25 years age in district Etawah and neighbouring areas of Uttar Pradesh, India.Methods: The study was planned to determine the prevalence of diabetes mellitus in rural community by health camp and door to door approach. Fasting capillary blood glucose was first determined using a glucose meter (SD check code free, SD biosensor Inc. Korea). All the adults were given 75gm of glucose dissolved in 200ml water which was drunk over a period of up to 5 minutes and the 2-hour post load capillary blood glucose was estimated. Diabetic status was confirmed by taking blood samples for fasting and postprandial blood sugar levels in a fluoride vacutainer. Fasting plasma glucose ≥126mg/dl and or 2-hour postprandial glucose ≥200mg/dl were taken as the diagnostic criteria for diagnosis.Results: Prevalence of type 2 diabetes in the rural population was found to be 8.03%. Prevalence was higher in female population (9.91%) as compared to males (6.79%). 19.74 % of participants over 70 yrs of age were diabetics while diabetes was present only in 2.95% of participants in the age group of 25-39 year. The maximum number of diabetes were in the age group of 50-59 years. 10.04 % of participants were diagnosed to be Prediabetics. 35.77% of the diabetics were newly diagnosed.Conclusions:Present study shows there is high prevalence of type 2 diabetes in rural area of western Uttar Pradesh, India.

Prevalence of hypertension in rural population of Central India

Background: Hypertension is an important public health problem in both rural and urban areas of economically developed as well as developing nations. It is a chronic medical condition and is one of the most common life threatening non-communicable disease. It is an asymptomatic condition, symptoms do not arise unless the complications develop which result in delayed diagnosis and treatment especially among the uneducated and unexplained social groups such as rural population. Present study was an attempt to provide data on hypertension in rural area of central India. The objective of present study was to estimate the prevalence of hypertension in rural population above 18 years of age in Etawah and neighbouring districts of Uttar Pradesh, India.Methods: The study was planned to determine the prevalence of hypertension in rural community by health camp and door to door approach. BP measurements were made after the subject had rested for at least 5 minutes in a seated position using mercury sphygmomanometer. The first blood pressure measurement was taken after obtaining socio-demographic information from the study subject, while the second was recorded after 5 minutes.Results: The prevalence of hypertension was found to be 17%, which was observed to be higher among female i.e. 170 (18.3%) individuals than males 153 (15.8%) individuals. The prevalence of hypertension was observed to be higher among the older individuals. It was found to be 5.26 times higher in older (>50 years) than the younger (<30 years) age group. We found prehypertension in 65.74%, Stage I hypertension in 11.33% and stage II hypertension in 5.69% individuals.Conclusions: Present study showed that high prevalence of hypertension in rural area of Western Uttar Pradesh, Central India

Evaluation of a Mixed Meal Test for Diagnosis and Characterization of PancrEaTogEniC DiabeTes Secondary to Pancreatic Cancer and Chronic Pancreatitis: Rationale and Methodology for the DETECT Study From the Consortium for the Study of Chronic Pancreatitis, Diabetes, and Pancreatic Cancer

Pancreatogenic diabetes mellitus is most commonly the result of chronic pancreatitis but can also occur secondary to pancreatic cancer. The early identification of pancreatogenic diabetes and distinction from the more prevalent type 2 diabetes are clinically significant; however, currently, there is no validated method to differentiate these diabetes subtypes. We describe a study, "Evaluation of a Mixed Meal Test for Diagnosis and Characterization of PancrEaTogEniC DiabeTes Secondary to Pancreatic Cancer and Chronic Pancreatitis: the DETECT study," that seeks to address this knowledge gap. The DETECT study is a multicenter study that will examine differences in hormone and glucose excursions after a mixed meal test. The study will also create a biorepository that will be used to evaluate novel diagnostic biomarkers for differentiating these diabetes subtypes

Maintaining Diversity of Integrated Rice and Fish Production Confers Adaptability of Food Systems to Global Change

Rice and fish are preferred foods, critical for healthy and nutritious diets, and provide the foundations of local and national economies across Asia. Although transformations, or "revolutions," in agriculture and aquaculture over the past half-century have primarily relied upon intensified monoculture to increase rice and fish production, agroecological approaches that support biodiversity and utilize natural processes are particularly relevant for achieving a transformation toward food systems with more inclusive, nutrition-sensitive, and ecologically sound outcomes. Rice and fish production are frequently integrated within the same physical, temporal, and social spaces, with substantial variation amongst the types of production practice and their extent. In Cambodia, rice field fisheries that strongly rely upon natural processes persist in up to 80% of rice farmland, whereas more input and infrastructure dependent rice-shrimp culture is expanding within the rice farmland of Vietnam. We demonstrate how a diverse suite of integrated production practices contribute to sustainable and nutrition-sensitive food systems policy, research, and practice. We first develop a typology of integrated production practices illustrating the nature and degree of: (a) fish stocking, (b) water management, (c) use of synthetic inputs, and (d) institutions that control access to fish. Second, we summarize recent research and innovations that have improved the performance of each type of practice. Third, we synthesize data on the prevalence, outcomes, and trajectories of these practices in four South and Southeast Asian countries that rely heavily on fish and rice for food and nutrition security. Focusing on changes since the food systems transformation brought about by the Green Revolution, we illustrate how integrated production practices continue to serve a variety of objectives to varying degrees: food and nutrition security, rural livelihood diversification and income improvement, and biodiversity conservation. Five shifts to support contemporary food system transformations [i.e., disaggregating (1) production practices and (2) objectives, (3) utilizing diverse metrics, (4) valuing emergent, place-based innovation, (5) building adaptive capacity] would accelerate progress toward Sustainable Development Goal 2, specifically through ensuring ecosystem maintenance, sustainable food production, and resilient agricultural practices with the capacity to adapt to global change.This work was undertaken as part of the CGIAR Research Program on Fish Agri-Food Systems (FISH) led by WorldFish with contribution from the CGIAR Research program on Water Land and Ecosystems (WLE) led by the International Water Management Institute.

Emissions of non-methane volatile organic compounds from combustion of domestic fuels in Delhi, India

Twenty-nine different fuel types used in residential dwellings in northern India were collected from across Delhi (76 samples in total). Emission factors of a wide range of non-methane volatile organic compounds (NMVOCs) (192 compounds in total) were measured during controlled burning experiments using dualchannel gas chromatography with flame ionisation detection (DC-GC-FID), two-dimensional gas chromatography (GC×GC-FID), proton-transfer-reaction time-of-flight mass spectrometry (PTR-ToF-MS) and solid-phase extraction two-dimensional gas chromatography with time-offlight mass spectrometry (SPE-GC×GC-ToF-MS). On average, 94% speciation of total measured NMVOC emissions was achieved across all fuel types. The largest contributors to emissions from most fuel types were small non-aromatic oxygenated species, phenolics and furanics. The emission factors (in g kg-1) for total gas-phase NMVOCs were fuelwood (18.7, 4.3-96.7), cow dung cake (62.0, 35.3-83.0), crop residue (37.9, 8.9-73.8), charcoal (5.4, 2.4-7.9), sawdust (72.4, 28.6-115.5), municipal solid waste (87.3, 56.6- 119.1) and liquefied petroleum gas (5.7, 1.9-9.8). The emission factors measured in this study allow for better characterisation, evaluation and understanding of the air quality impacts of residential solid-fuel combustion in India

Emissions of intermediate-volatility and semi-volatile organic compounds from domestic fuels used in Delhi, India

Biomass burning emits significant quantities of intermediate-volatility and semi-volatile organic compounds (I/SVOCs) in a complex mixture, probably containing many thousands of chemical species. These components are significantly more toxic and have poorly understood chemistry compared to volatile organic compounds routinely quantified in ambient air; however, analysis of I/SVOCs presents a difficult analytical challenge. The gases and particles emitted during the test combustion of a range of domestic solid fuels collected from across Delhi were sampled and analysed. Organic aerosol was collected onto Teflon (PTFE) filters, and residual low-volatility gases were adsorbed to the surface of solid-phase extraction (SPE) discs. A new method relying on accelerated solvent extraction (ASE) coupled to comprehensive two-dimensional gas chromatography with time-of-flight mass spectrometry (GC×GC-ToF-MS) was developed. This highly sensitive and powerful analytical technique enabled over 3000 peaks from I/SVOC species with unique mass spectra to be detected. A total of 15 %-100% of gas-phase emissions and 7 %-100% of particle-phase emissions were characterised. The method was analysed for suitability to make quantitative measurements of I/SVOCs using SPE discs. Analysis of SPE discs indicated phenolic and furanic compounds were important for gas-phase I/SVOC emissions and levoglucosan to the aerosol phase. Gas- and particle-phase emission factors for 21 polycyclic aromatic hydrocarbons (PAHs) were derived, including 16 compounds listed by the US EPA as priority pollutants. Gas-phase emissions were dominated by smaller PAHs. The new emission factors were measured (mg kg-1) for PAHs from combustion of cow dung cake (615), municipal solid waste (1022), crop residue (747), sawdust (1236), fuelwood (247), charcoal (151) and liquefied petroleum gas (56). The results of this study indicate that cow dung cake and municipal solid waste burning are likely to be significant PAH sources, and further study is required to quantify their impact alongside emissions from fuelwood burning

Identification of Salt Stress Biomarkers in Romanian Carpathian Populations of Picea abies (L.) Karst

The Norway spruce (Picea abies), the most important tree species in European forests, is relatively sensitive to salt and does not grow in natural saline environments. Yet many trees are actually exposed to salt stress due to the common practice of de-icing of mountain roads in winter, using large amounts of NaCl. To help develop strategies for an appropriate use of reproductive seed material on reforestation sites, ensuring better chances of seedling survival in salt-affected areas, we have studied the responses of young spruce seedlings to salt treatments. The specific aim of the work was to identify the optimal salt stress biomarkers in Picea abies, using as experimental material seedlings obtained by germination of seeds with origin in seven populations from the Romanian Carpathian Mountains. These responses included general, conserved reactions such as the accumulation of ions and different osmolytes in the seedlings needles, reduction in photosynthetic pigments levels, or activation of antioxidant systems. Although changes in the contents of different compounds involved in these reactions can be associated to the degree of stress affecting the plants, we propose that the (decreasing) levels of total phenolics or total carotenoids and the (increasing) levels of Na+ or K+ ions in Picea abies needles, should be considered as the most reliable and useful biomarkers for salt stress in this species. They all show very high correlation with the intensity of salt stress, independently of the genetic background of the seeds parental population, and relatively easy, quantitative assays are available to determine their concentrations, requiring simple equipment and little amount of plant material.Funding: Sorin Schiop is a PhD student at the University of Agricultural Sciences and Veterinary Medicine Cluj-Napoca.
