Socio-cultural influences on the behaviour of South Asian women with diabetes in pregnancy: qualitative study using a multi-level theoretical approach

BACKGROUND: Diabetes in pregnancy is common in South Asians, especially those from low-income backgrounds, and leads to short-term morbidity and longer-term metabolic programming in mother and offspring. We sought to understand the multiple influences on behaviour (hence risks to metabolic health) of South Asian mothers and their unborn child, theorise how these influences interact and build over time, and inform the design of culturally congruent, multi-level interventions. METHODS: Our sample for this qualitative study was 45 women of Bangladeshi, Indian, Sri Lankan, or Pakistani origin aged 21-45 years with a history of diabetes in pregnancy, recruited from diabetes and antenatal services in two deprived London boroughs. Overall, 17 women shared their experiences of diabetes, pregnancy, and health services in group discussions and 28 women gave individual narrative interviews, facilitated by multilingual researchers, audiotaped, translated, and transcribed. Data were analysed using the constant comparative method, drawing on sociological and narrative theories. RESULTS: Key storylines (over-arching narratives) recurred across all ethnic groups studied. Short-term storylines depicted the experience of diabetic pregnancy as stressful, difficult to control, and associated with negative symptoms, especially tiredness. Taking exercise and restricting diet often worsened these symptoms and conflicted with advice from relatives and peers. Many women believed that exercise in pregnancy would damage the fetus and drain the mother's strength, and that eating would be strength-giving for mother and fetus. These short-term storylines were nested within medium-term storylines about family life, especially the cultural, practical, and material constraints of the traditional South Asian wife and mother role and past experiences of illness and healthcare, and within longer-term storylines about genetic, cultural, and material heritage - including migration, acculturation, and family memories of food insecurity. While peer advice was familiar, meaningful, and morally resonant, health education advice from clinicians was usually unfamiliar and devoid of cultural meaning. CONCLUSIONS: 'Behaviour change' interventions aimed at preventing and managing diabetes in South Asian women before and during pregnancy are likely to be ineffective if delivered in a socio-cultural vacuum. Individual education should be supplemented with community-level interventions to address the socio-material constraints and cultural frames within which behavioural 'choices' are made

Use of the analysis of the volatile faecal metabolome in screening for colorectal cancer

Diagnosis of colorectal cancer is an invasive and expensive colonoscopy, which is usually carried out after a positive screening test. Unfortunately, existing screening tests lack specificity and sensitivity, hence many unnecessary colonoscopies are performed. Here we report on a potential new screening test for colorectal cancer based on the analysis of volatile organic compounds (VOCs) in the headspace of faecal samples. Faecal samples were obtained from subjects who had a positive faecal occult blood sample (FOBT). Subjects subsequently had colonoscopies performed to classify them into low risk (non-cancer) and high risk (colorectal cancer) groups. Volatile organic compounds were analysed by selected ion flow tube mass spectrometry (SIFT-MS) and then data were analysed using both univariate and multivariate statistical methods. Ions most likely from hydrogen sulphide, dimethyl sulphide and dimethyl disulphide are statistically significantly higher in samples from high risk rather than low risk subjects. Results using multivariate methods show that the test gives a correct classification of 75% with 78% specificity and 72% sensitivity on FOBT positive samples, offering a potentially effective alternative to FOBT

Zinc finger protein ZBTB20 expression is increased in hepatocellular carcinoma and associated with poor prognosis

<p>Abstract</p> <p>Background</p> <p>Our previous studies showed that ZBTB20, a new BTB/POZ-domain gene, could negatively regulate α feto-protein and other liver-specific genes, concerning such as bio-transformation, glucose metabolism and the regulation of the somatotropic hormonal axis. The aim of this study is to determine the potential clinical implications of ZBTB20 in hepatocellular carcinoma (HCC).</p> <p>Methods</p> <p>Quantitative real-time RT-PCR and Western blot analyses were used to detect expression levels of ZBTB20 in 50 paired HCC tumorous and nontumorous tissues and in 20 normal liver tissues. Moreover, expression of ZBTB20 was assessed by immunohistochemistry of paired tumor and peritumoral liver tissue from 102 patients who had undergone hepatectomy for histologically proven HCC. And its relationship with clinicopathological parameters and prognosis was investigated.</p> <p>Results</p> <p>Both messenger RNA and protein expression levels of ZBTB20 were elevated significantly in HCC tissues compared with the paired non-tumor tissues and normal liver tissues. Overexpressed ZBTB20 protein in HCC was significantly associated with vein invasion (<it>P </it>= 0.016). Importantly, the recurrence or metastasis rates of HCCs with higher ZBTB20 expression were markedly greater than those of HCCs with lower expression (<it>P </it>= 0.003, <it>P </it>= 0.00015, respectively). Univariate and multivariate analyses revealed that ZBTB20 overexpression was an independent prognostic factor for HCC. The disease-free survival period and over-all survival period in patients with overexpressed ZBTB20 in HCC was significantly reduced.</p> <p>Conclusions</p> <p>The expression of ZBTB20 is increased in HCC and associated with poor prognosis in patients with HCC, implicating ZBTB20 as a candidate prognostic marker in HCC.</p

Understanding the consumption of folic acid during preconception, among Pakistani, Bangladeshi and white British mothers in Luton, UK: a qualitative study

Background To review the similarities and differences in Pakistani, Bangladeshi and White British mothers health beliefs (attitudes, knowledge and perceptions) and health behaviour regarding their consumption of folic acid pre-conception, to reduce the risk of neural tube defects. Methods Our study used a descriptive qualitative research approach, implementing face-to-face focus group discussions with Pakistani, Bangladeshi or White British mothers (normal birth outcomes and mothers with poor birth outcomes) and semi-structured interviews or focus groups with service providers using semi-structured topic guides. This method is well suited for under researched areas where in-depth information is sought. There were three sample groups: 1. Pakistani, Bangladeshi and White British mothers with normal birth outcomes (delivery after 37 weeks of gestation, in the preceding 6 to 24 months, weighing 2500 g and living within a specified postcode area in Luton, UK). 2. Pakistani Bangladeshi and white British bereaved mothers who had suffered a perinatal mortality (preceding 6 to 24 months, residing within a specificied postcode area). 3. Healthcare professionals working on the local maternity care pathway (i.e. services providing preconception, antenatal, antepartum and postpartum care). Transcribed discussions were analysed using the Framework Analysis approach. Results The majority of mothers in this sample did not understand the benefits or optimal time to take folic acid pre-conception. Conversely, healthcare professionals believed the majority of women did consume folic acid, prior to conception. Conclusions There is a need to increase public health awareness of the optimal time and subsequent benefits for taking folic acid, to prevent neural tube defects.</p

Determination Of Carcinogenic Polycyclic Aromatic Hydrocarbons (Pahs), Anthracene In Different Variety Of Fish Samples In The Bangsai River Of Bangladesh

Carcinogenic polycyclic aromatic hydrocarbons (PAHs), widely scattered in the environment because of inadequate combustion of fuels, are an important class of toxicological compounds. In the past decade, PAHs have drawn considerable attention because of their possible contamination to the environment and foodstuffs. A crude extract of the fish samples collected from the most polluted part of Bangsai river at Saver industrial zone was analyzed for the presence of polycyclic aromatic hydrocarbon, anthracene, by gas chromatography-mass spectrometry (GC-MS). A suitable procedure for the extraction of PAHs from the fish sample was developed. A multi-layer clean-up (silica gel) column was used, followed by glass fiber filter (GFF) paper to eliminate the interfering organic compounds as well as lipids, fat and foreign particles. It was observed that PAHs deposition on the samples takes place in different morphological parts of the biological materials. Analysis was made for environmentally important PAHs and the results, the methods and some associated problems are discussed. Anthracene was found in almost all fish samples with the concentration in edible fishes collected from the Bangsai river being 0.761 to 3.294 µg/g. This concentration is within the range reported for other comparable regions of the world. Thus, it was suggested PAHs is oil contamination originating from the effluents of different industries such as tannery, dye, plastic, chemical, fertilizer or spillage’s and/or heavy ship traffic. However, the high concentration of carcinogenic anthracene encountered in these fishes should be considered serious as it is hazardous to human health. Based on fish consumption by Bangladeshi population, the daily intake of total carcinogens was 0.15 ng/person/day. Recovery studies with fortified samples indicated that the recovery efficiency for anthracene was 85.32%. It is concluded that three fish samples: baim, bata and taki were contaminated by the various aspects such as industrial effluents, air, highway vehicle exhaust and highway tar samples

The multidimensional impacts of external price shocks on macroeconomic variables: Malaysian experiences from recession to economic instability

The 2008 to 2009 global external price shocks on foods and oil exert worldwide impacts on production, expenditure pattern, trade, welfare, internal resource allocation and ultimate impacts diverted to global recession, Malaysia is not an exception. Centering the world's (2008 to 2009) oil and food price catastrophe, here we investigate Malaysian experiences from recession to economic instability. An applied computable general equilibrium model is utilized in our study to simulate the Malaysian economic impacts by three scenarios. First is food import price increase by 20% (Scenario 1), second is the oil price catastrophe by 40% (Scenario 2) and finally a scenario that combines Scenarios 1 and 2 simultaneously (Scenario 3). Our results depict the multidimensional impacts on major macroeconomic indicators from recession to economic instability. Our results indicate that, price catastrophe either in Scenario 1 or 2, or in Scenario 3, depress overall Malaysian domestic outputs and exports. Reduced output also reduces employment, thus causing a fall in household's income. Overall imports also decreased by 0.2, 1.5, and 1.7% respectively, in all scenarios that specify consumers can afford less quantity of both domestic and imported goods; is the clear indication of recession and economic instability. Our study can be a message to policy makers, who are considering recession and trade policy together

Aislamiento de zederona de los rizomas de Zingiber zerumbet y su actividad antiestafilocócica

A sesquiterpene, zederone (1), was isolated from the crude ethanolic extract of the rhizomes of Zingiber zerumbet (L.) Smith. It is the first time report of isolation of this compound from the genus Zingiber. Its structure was established by a series of spectral data including high-field NMR (both 1D and 2D) and MS. The antibacterial activity of this compound was determined against a number of multi-drug resistant and methicillin-resistant Staphylococcus aureus strains (SA1199B, ATCC25923, XU212, RN4220 and EMRSA15) and minimum inhibitory concentration (MIC) values were found to be in the range of 64-128 ?g/ml

The intake pattern and feed preference of layer hens selected for high or low feed conversion ratio.

Feed accounts for the greatest proportion of egg production costs and there is substantial variation in feed to egg conversion ratio (FCR) efficiency between individual hens. Despite this understanding, there is a paucity of information regarding layer hen feeding behaviour, diet selection and its impact on feed efficiency. It was hypothesised that variation in feed to egg conversion efficiency between hens may be influenced by feeding behaviour. For this experiment, two 35-bird groups of ISA Brown layers were selected from 450 individually caged hens at 25-30 weeks of age for either low FCR 2.1 ± 0.02 (low feed efficiency (LFE)). For each of these 70 hens, intake of an ad-libitum mash diet at 2-minute time intervals, 24 h a day, for 7 days was determined alongside behavioural assessment and estimation of the selection of components of the mash. The group selected for HFE had a lower feed intake, similar egg mass and associated lower FCR when compared with the LFE group. Whilst feed intake patterns were similar between HFE and LFE hens, there was a distinct intake pattern for all layer hens with intake rate increasing from 0300 to 1700 h with a sharp decline to 2200 h. High feed efficiency hens selected a diet with 25% more ash and 4% less gross energy than LFE hens. The LFE hens also spent more time eating with more walking events, but less time spent resting, drinking, preening and cage pecking events as compared with HFE hens. In summary, there was no contrasting diurnal pattern of feed consumption behaviour between the groups ranked on feed efficiency, however high feed efficiency hens consumed less feed and selected a diet with greater ash content and lower gross energy as compared with LFE hens. Our work is now focused on individual hen diet selection from mash diets with an aim of formulating precision, targeted diets for greater feed efficiency
