RESUMO
Cefdinir being a semi-synthetic third generation cephalosporin antibiotic is considered as an emerging pollutant which demands removal from environment. Degradation of cefdinir by yeast Candida sp. SMN04 immobilized on various single and hybrid matrices was investigated using entrapment method. The biofilm forming ability of Candida sp. was evaluated by crystal violet staining assay and the formed biofilm was monitored by SEM and AFM analysis. The amount of exopolysaccharides (EPS) produced by Candida sp. was quantified and characterized by FTIR, HPLC and TGA analysis respectively. Cefdinir degradation from pharmaceutical wastewater was found to be 96.6% and 92.2% by PVA-alginate immobilized yeas tand yeast biofilm formed on gravels over a period of 48 h in batch mode. Effectiveness of the process was also tested involving continuous-flow column studies. This is the first successful attempt on cefdinir degradation using immobilized yeast cells and yeast biofilm on solid substrate.
RESUMO
Justification: The need to revise Indian Academy of Pediatrics (IAP) growth charts for 5- to 18-year-old Indian children and adolescents was felt as India is in nutrition transition and previous IAP charts are based on data which are over two decades old. Process: The Growth Chart Committee was formed by IAP in January 2014 to design revised growth charts. Consultative meeting was held in November 2014 in Mumbai. Studies performed on Indian children’s growth, nutritional assessment and anthropometry from upper and middle socioeconomic classes in last decade were identified. Committee contacted 13 study groups; total number of children in the age group of 5 to 18 years were 87022 (54086 boys). Data from fourteen cities (Agartala, Ahmadabad, Chandigarh, Chennai, Delhi, Hyderabad, Kochi, Kolkata, Madurai, Mumbai, Mysore, Pune, Raipur and Surat) in India were collated. Data of children with weight for height Z scores >2 SD were removed from analyses. Data on 33148 children (18170 males, 14978 females) were used to construct growth charts using Cole’s LMS method. Objectives: To construct revised IAP growth charts for 5-18 year old Indian children based on collated national data from published studies performed on apparently healthy children and adolescents in the last 10 years. Recommendations: The IAP growth chart committee recommends these revised growth charts for height, weight and body mass index (BMI) for assessment of growth of 5-18 year old Indian children to replace the previous IAP charts; rest of the recommendations for monitoring height and weight remain as per the IAP guidelines published in 2007. To define overweight and obesity in children from 5-18 years of age, adult equivalent of 23 and 27 cut-offs presented in BMI charts may be used. IAP recommends use of WHO standards for growth assessment of children below 5 years of age.
