Prevalence and risk factors for vitamin C deficiency in north and south India: a two centre population based study in people aged 60 years and over.

BACKGROUND: Studies from the UK and North America have reported vitamin C deficiency in around 1 in 5 men and 1 in 9 women in low income groups. There are few data on vitamin C deficiency in resource poor countries. OBJECTIVES: To investigate the prevalence of vitamin C deficiency in India. DESIGN: We carried out a population-based cross-sectional survey in two areas of north and south India. Randomly sampled clusters were enumerated to identify people aged 60 and over. Participants (75% response rate) were interviewed for tobacco, alcohol, cooking fuel use, 24 hour diet recall and underwent anthropometry and blood collection. Vitamin C was measured using an enzyme-based assay in plasma stabilized with metaphosphoric acid. We categorised vitamin C status as deficient (28 µmol/L). We investigated factors associated with vitamin C deficiency using multivariable Poisson regression. RESULTS: The age, sex and season standardized prevalence of vitamin C deficiency was 73.9% (95% confidence Interval, CI 70.4,77.5) in 2668 people in north India and 45.7% (95% CI 42.5,48.9) in 2970 from south India. Only 10.8% in the north and 25.9% in the south met the criteria for adequate levels. Vitamin C deficiency varied by season, and was more prevalent in men, with increasing age, users of tobacco and biomass fuels, in those with anthropometric indicators of poor nutrition and with lower intakes of dietary vitamin C. CONCLUSIONS: In poor communities, such as in our study, consideration needs to be given to measures to improve the consumption of vitamin C rich foods and to discourage the use of tobacco

When facebook is (Not) enough: hybridity in the media and political strategies of leftist youth organisations

The key term of this chapter is ‘hybridity’, referring to the blurring lines between media and political spheres, and between different media and their logics. We draw on two ethnographic studies of two youth-led leftist organisations aiming to impact institutional politics: the Czech Idealists and British Labour Party campaign group Momentum. This chapter focuses on intertwined media and political strategies employed by both organisations in changing European political and media environments. We ask: What is the role of media in both the communication practices and political agency of these groups? Within these two case studies, we highlight the professionalisation of the communication repertoires employed by their members, investigating each group’s diverse and innovative strategies for using media to influence politics

Effect of shock wave reapplication on urinary n-acetyl-beta-glucosaminidase in canine kidney

OBJECTIVE: Renal tubular damage can be assessed with the aid of urinary dosing of N-acetyl-beta-glucosaminidase (NAG) and it is possible to demonstrate a significant correlation between shock wave and damage to renal parenchyma. The objective of this study was to assess the effect of shock wave reapplication over urinary NAG in canine kidney. MATERIALS AND METHODS: The authors submitted 10 crossbred dogs to 2 applications of 2000 shock waves in a 24-hour interval in order to assess urinary NAG values after 12, 24, 36 and 48 hours. RESULTS: Twelve hours following the first shockwave application there was an increase in NAG of 6.47 ± 5.44 u/g creatinine (p < 0.05). Twelve hours and 24 h following the second application there was no increase in the urinary enzyme, - 2.56 ± - 7.36 u/g creatinine and 2.89 ± - 7.27 u/g creatinine, respectively (p > 0.05). CONCLUSION: Shock wave reapplication with a 24-hour interval did not cause any increase in urinary NAG

Changes in Lips, Cheeks And Tongue Pressures After Upper Incisor Protrusion in Class Ii Division 2 Malocclusion: A Prospective Study

Background The etiology of Class II division 2 (CII/2) malocclusion focuses on heredity; however lip, cheek, and tongue pressures that are associated with the environmental effect are considered to have an effect. The aim of this study was to evaluate the relation between perioral pressures and the upper incisor inclination in CII/2 malocclusion. Methods Twenty patients (8 females, 12 males; mean age 10.29 ± 0.90 years) with CII/2 malocclusion were included in the study group, and 15 patients (5 females, 10 males; mean age 10.56 ± 1.06 years) with Class I malocclusion were included. The upper incisors were protruded with a utility arch (0.016 × 0.022 in. blue elgiloy wire). Perioral pressure assessment was made with the Iowa Oral Pressure Instrument. Upper lip pressure, lower lip pressure, vertical lip pressure, left-right buccal pressures, swallowing, and maximum tongue pressures were measured. Repeated measure ANOVA was used to test the intragroup differences. Intergroup comparisons were made using two-way repeated measure ANOVA with Bonferroni correction. Relationships between the variables were analyzed using rank correlation (Spearman’s rho). The significance for all statistical tests was predetermined at p < 0.05. Results A significant change occurred in the upper lip pressure, lower lip pressure, and vertical lip pressure; however, significant difference was not found between the groups. Upper lip pressure increased significantly in both groups. In the CII/2 group, lower lip pressure increased after protrusion and decreased after retention, while vertical lip pressure decreased and then increased significantly. Left buccal pressure changes between the groups were not parallel. Right buccal pressure, swallowing, and maximum tongue pressure changes were not statistically significant. Statistically significant correlation was found between U1-NA (mm) and vertical lip pressure (r −0.467). Conclusions In the CII/2 group, upper lip pressure increased only in retention. Lower lip pressure increased and vertical lip pressure decreased after protrusion. Nevertheless, these changes did not remain stable after the retention period. The difference between groups was not statistically significant at the end of retention.PubMedWoSScopu
