Determinants of maternal health care utilization at urban slums in Northeast India: a cross-sectional study

Background: Factors affecting maternal health care utilization determine maternal mortality rate (MMR). Therefore this study has been carried out to out to assess the level and determinants of maternal health care service utilization in an urban slum of north-east India. Methods: A cross-sectional study design was used. The study area comprised of four municipal wards with well-defined geographical boundaries. All married women in the age group 18-45 years who were either pregnant and/ or had at least one child under 3 years of age on the day of survey residing in that area for a minimum of one year were the study population. Data collection was done by house-to-house visit. Descriptive analysis and chi-square test was used for data analysis. Results: Adequate utilization of IFA and TT was 86.3% and 84.4%, respectively. Adequate utilization of maternal health care was found to be 79.8% and 20.2% respectively. Age, educational status, income of the participants and birth order of the relevant child was found to be significantly associated with the maternal health care utilization. Conclusions: The study concludes that maternal health care utilization was found adequate among 79.8% of study participants, out of which antenatal care, intranatal care and postnatal care utilization rate was found in 85.4%, 89.8% and 82.5% respectively. Age, education, income of the women and birth order of their children were significantly associated with maternal health care utilization.

Progress and prediction of multicomponent quantification in complex systems with practical LC-UV methods / 药物分析学报

Complex systems exist widely,including medicines from natural products,functional foods,and bio-logical samples.The biological activity of complex systems is often the result of the synergistic effect of multiple components.In the quality evaluation of complex samples,multicomponent quantitative analysis(MCQA)is usually needed.To overcome the difficulty in obtaining standard products,scholars have proposed achieving MCQA through the"single standard to determine multiple components(SSDMC)"approach.This method has been used in the determination of multicomponent content in natural source drugs and the analysis of impurities in chemical drugs and has been included in the Chinese Pharmacopoeia.Depending on a convenient(ultra)high-performance liquid chromatography method,how can the repeatability and robustness of the MCQA method be improved?How can the chromatography conditions be optimized to improve the number of quantitative components?How can computer software technology be introduced to improve the efficiency of multicomponent analysis(MCA)?These are the key problems that remain to be solved in practical MCQA.First,this review article summarizes the calculation methods of relative correction factors in the SSDMC approach in the past five years,as well as the method robustness and accuracy evaluation.Second,it also summarizes methods to improve peak capacity and quantitative accuracy in MCA,including column selection and two-dimensional chromatographic analysis technology.Finally,computer software technologies for predict-ing chromatographic conditions and analytical parameters are introduced,which provides an idea for intelligent method development in MCA.This paper aims to provide methodological ideas for the improvement of complex system analysis,especially MCQA.

Quantitative Detection of Aflatoxin B1 in Traditional Chinese Medicine by Colloidal Gold Immunochromatography / 中国药学杂志

OBJECTIVE：To explore the feasibility of using colloidal gold immunochromatography for quantitative detection of aflatoxin B1 in traditional Chinese medicine. METHODS：Negative samples were used to investigate matrix interference by different levels of spikes.The rapid inspection performance was evaluated by examining the precision, sensitivity, linearity, repeatability and recovery rate. The sample was determined by rapid test method and verified by HPLC. RESULTS：High-concentration and low-concentration aflatoxin B1 reference materials were added to the negative sample matrix. After the measurement, it was found that there were matrix interferences in the samples such as tangerine peel and cassia seed, and the interference was greater when the concentration was increased. So high dilution factor was used to reduce the interference. The precision RSD of the rapid test method was 4.6% (n=10), the reproducibility RSD was 4.1% (n=6), and the recoveries of different samples were between 72.8% and 112.8%. The overall performance of the method was good. A total of 43 batches of 19 kinds of medicinal materials such as silkworm, cockroach and leeches were detected by two methods. The coincidence rate between the fast test and the HPLC test was 83.7%. Therefore, the results obtained by the two detection methods were considered to be approximate. CONCLUSION：Colloidal gold immunochromatographic rapid test method can be used for the quantitative detection of aflatoxin B1 in some traditional Chinese medicines, and provides technical support for the establishment and improvement of relevant rapid detection standard methods.

Detecção de resistência às fluoroquinolonas em Campylobacter isolados de frangos de criação orgânica / Detection of fluoroquinolone resistance in Campylobacter strains from organic poultry

Estudos têm revelado que a resistência às quinolonas em cepas de Campylobacter está relacionada à presença da mutação Treonina-86 para Isoleucina. Com o objetivo de investigar a presença dessa mutação em cepas de Campylobacter sensíveis e resistentes à ciprofloxacina e enrofloxacina, o conteúdo cecal de 80 frangos de corte de criação orgânica, abatidos sob Serviço de Inspeção Estadual (S.I.E.) do Estado do Rio de Janeiro, foram coletados e investigados para a presença de Campylobacter. A determinação da resistência à ciprofloxacina e enrofloxacina foi feita pela técnica de difusão em disco e de diluição em ágar para determinação da Concentração Inibitória Mínima (CIM). A detecção da mutação na Região Determinante de Resistencia às Quinolonas (RDRQ) no gene gyrA foi realizada através de sequenciamento. Campylobacter foi isolado a partir de 100% das amostras avaliadas, sendo 68,75% correspondente à C. jejuni e 31,25% à C. coli. No teste de difusão em disco, 100% das cepas foram resistentes à ciprofloxacina e 56,25% das cepas foram resistentes à enrofloxacina. No teste de diluição em ágar, todas as cepas foram resistentes à ciprofloxacina apresentando CIM variando de ≥ 16-64μg/mL, e resistência ou resistência intermediaria à enrofloxacina foi detectada em 42,50% (CIM ≥ 4-32μg/mL) e 38,75% (CIM = 2μg/mL) das cepas, respectivamente. A mutação Tre-86-Ile, foi observada em 100% das cepas analisadas. Além dessa mutação, foram observadas outras mutações não silenciosas (Val-73-Glu, Ser-114-Leu, Val-88-Asp, Ala-75-Asp, Ser-119-Gli, Arg-79-Lis) e mutações silenciosas (His-81-His, Ser-119-Ser, Ala-120-Ala, Fen-99-Fen, Ala-122-Ala, Gli-74-Gli, Ile-77-Ile, Ala-91-Ala, Leu-92-Leu, Val-93-Val, Ile-106-Ile, Tre-107-Tre, Gli-113-Gli, Ile-115-Ile, Gli-110-Gli).

Studies have shown that resistance to quinolones in Campylobacter strains is related with Threonine-86-Isoleucine mutation. In order to investigate the presence of this mutation in sensitive and resistant Campylobacter strains to ciprofloxacin and enrofloxacin, the cecal contents of 80 broilers from organic raising chickens, slaughtered under State Inspection Service (S.I.S) of the State of Rio de Janeiro, were collected and tested for the presence of Campylobacter. The determination of ciprofloxacin and enrofloxacin susceptibility was done by disk diffusion and agar dilution methods for determining the Minimum Inhibitory Concentration (MIC). The detection of mutation in Quinolone Resistance Determinant Region (QRDR) in gyrA gene was done by sequencing. Campylobacter was isolated from 100% of the samples, being 68.75% C. jejuni and 31.25% C. coli. By the disk diffusion method, resistance to ciprofloxacin was observed in all isolates and 56.25% of the strains were resistant to enrofloxacin. By agar dilution method, all strains were resistant to ciprofloxacin (MIC ≥ 16μg/mL to ≥ 64μg/mL) and full and intermediate resistance to enrofloxacin was detected in 42.50% (MIC ≥ 4-32μg/mL) and 38.75% (MIC =2μg/mL) of the strains, respectively. Mutation Thr-86-Ile was observed in 100% of the isolates investigated. In addition to this mutation, others no silent mutations (Val-73-Glu, Ser-114-Leu, Val-88-Asp, Ala-75-Asp, Gly-119-Ser, Arg-79-Lys) and silent mutations (His-81-His, Ser-119-Ser, Ala-120-Ala, Phe-99-Phe, Ala-122-Ala, Gly-74-Gly, Ile-77-Ile, Ala-91-Ala, Leu-92-Leu, Val-93-Val, Ile-106-Ile, Thr-107-Thr, Gly-113-Gly, Ile-115-Ile, Gly-110-Gly) were detected. All the enrofloxacin-sensitive strains by the phenotypic methods had the Thr-86 to Ile substitution, which suggests other mechanisms contributing to enrofloxacin resistance in Campylobacter...

Logic Problem Analysis on Determination of Syndrome-attribution in A Variety of Animal Model Establishment Methods / 世界科学技术-中医药现代化

Intervening animals by pathogen of traditional Chinese medicine (TCM) to establish animal model is the most common and easiest method to determine syndrome attribute of an animal model. However, the underlying prob-lem of this modeling method is that the concept of wind, cold and dampness in the nature are confused with the syn-drome of wind-cold-dampness summarized by abnormal appearance of clinical patients. The typical animal model establishment are through the methods of wind blowing, low temperature freezing, cold water immersion, environmen-tal humidity increasing. Modern medical modeling methods, such as chemicals, organ resections, are also used in the establishment of animal models. Then, the syndrome-attribution of modeling animal is evaluated by physicochemical indexes of modern medicine which is one of modeling methods that have been used by academia in early times. But animal model established by this method is a kind of disease model which is lack of sufficient theoretical and clini-cal evidences. Therefore, the syndrome-attribution should be reappraised among this kind of animal models.

Reliability of Nutritional Screening Using DETERMINE Checklist for Elderly in Korean Rural Areas by Season / 대한지역사회영양학회지

It is very important to screen the elderly for nutritional risk, because nutritional status is a critical factor to maintain their health. Some nutrition checklists used in Korea for the elderly are from other countries. Reliability of those checklist in Korea is not studied enough. This survey was done for the elderly over 65-years-old who live in Hongcheon, An-dong, Dam-yang and Yeon-gi in Korea (subject; summer: 146, winter: 145) to study the reliability of DETERMINE checklist which is adopted widely in Korea. Using the score of DETERMINE checklist, the elderly were divided as high, middle and low risk groups. For nutritional assessment for those elderly, dietary assessment using 24 recall, anthropometry, biochemical assessment and health condition were used. Results for the checklist showed that percentage below EAR for energy intake and protein intake in winter were higher in the high risk group than other groups. The intakes of phosphorus and iron and most vitamins were below the DRI. The percentage of subjects with intake below DRI was highest in the high risk group. Sensitivity, specificity, and positive predictive values using the DETERMINE were calculated using 6 point as a cut-off point. Subjects were divided into two groups by MAR (MAR< 0.75:undernutrition, MAR< 0.75 : normal). Sensitivity recorded 49.4% and 34.3%, specificity did 61.9% and 65.4 and Positive predictive value did 62.1% and 46.0% each for summer and winter. Results of screening using DETERMINE Checklist were not matched with dietary assessment but not with anthropometric and biochemical measurement. In conclusion DETERMINE 'Checklist' is shown be a good screening tool for finding out risk groups for dietary intake in the elderly, It needs to verify reliability and validity through large-scale survey.
