    Objective: The current study was aimed at comparative quantitative phytochemical analysis of the leaves of S. italica collected from four districts in Limpopo province, South Africa, in order to establish whether geographical location have an effect on the accumulation of phytochemicals within the leaves of the plant species under study.Methods: The leaves of S. italica were collected from four districts in Limpopo province of South Africa namely; Capricorn, Sekhukhune, Vhembe and Waterberg districts, dried, ground to powder and extracted using different organic solvents. The extracts of the leaf samples from different locations were subjected to quantitative phytochemical analysis for total phenolic content, total tannin content, total flavonoid content and total saponin content using spectrophotometric measurements. The resultant quantities were analysed for statistical differences.Results: The leaf samples of S. italica from the four districts in Limpopo province showed significant differences (*p<0.05) in their phytochemical quantities, with main data expressed as meanƂĀ±SD. Total phenolic content was in highest amounts in leaf samples from Waterberg district compared to samples from other districts. Total tannin content was in highest amounts in the Vhembe district leaf samples compared to samples from other districts. Total flavonoid content was in highest amounts in the leaf samples from Waterberg district compared to samples from other districts. Total saponin content was in highest amounts in the Vhembe district leaf samples compared to samples from other districts.Conclusion: The findings of the study thus suggest that geographical location has an effect on the accumulation of phytochemicals in the leaves of S. italica

    Sustainability implementation challenges in food supply chains: a case of UK artisan cheese producers

    Get PDF
    Food supply chains are receiving increased attention due to rapid depletion of natural resources, increasing quality standards and rising food safety and security concerns. Implementing sustainability practices in food supply chains is believed to overcome such emerging challenges. However, limited studies address sustainability implementation concerns, particularly in cold food supply chains. Thus, this study attempts to identify factors hindering sustainability implementation in cold food chain networks by considering a case of UK artisan cheese producers. Survey data is utilised to identify and prioritise barriers for implementing sustainability following fuzzy analytic hierarchy process and sensitivity analysis. The analysis identified several key barriers, including initial investment cost, firm size and unawareness of government regulations. The internal barriers significantly dominate the implementation of sustainability practices in comparison to external barriers. Lack of consensus regarding the concept of sustainability by different stakeholders is observed to be an issue negatively affecting the level of integration in SMEs. Findings will help food and dairy SME's in gaining competitive advantage through the successful implementation of sustainability practices

    <p>Abstract</p> <p>Background</p> <p>High income nations are currently exhibiting increasing ethno-cultural diversity which may present challenges for nursing practice. We performed an integrative review of literature published in North America and Europe between 1990 and 2007, to map the state of knowledge and to identify nursing assessment tools/models which are have an associated research or empirical perspective in relation to ethno-cultural dimensions of nursing care.</p> <p>Methods</p> <p>Data was retrieved from a wide variety of sources, including key electronic bibliographic databases covering research in biomedical fields, nursing and allied health, and culture, e.g. CINAHL, MEDline, PUBmed, Cochrane library, PsycINFO, Web of Science, and HAPI. We used the Critical Appraisal Skills Programme tools for quality assessment. We applied Torraco's definition and method of an integrative review that aims to create new knowledge and perspectives on a given phenomena. To add methodological rigor with respect to the search strategy and other key review components we also used the principles established by the Centre for Reviews and Dissemination.</p> <p>Results</p> <p>Thirteen thousand and thirteen articles were retrieved, from which 53 full papers were assessed for inclusion. Eight papers met the inclusion criteria, describing research on a total of eight ethno-cultural assessment tools/models. The tools/models are described and synthesized.</p> <p>Conclusions</p> <p>While many ethno-cultural assessment tools exist to guide nursing practice, few are informed by research perspectives. An increased focus on the efficiency and effectiveness of health services, patient safety, and risk management, means that provision of culturally responsive and competent health services will inevitably become paramount.</p

    The study aimed to investigate the association between metabolic syndrome (MetS) and lifestyle risk factors among Ellisras adults. A cross-sectional study was conducted on 624 adults (306 males and 318 females). MetS was deļ¬ned according to the criteria of the International Diabetes Federation. The prevalence of MetS was 23.1% (8.6% males and 36.8 % females). Females appeared to have higher mean values for waist circumference (WC), fasting blood glucose (FBG), total cholesterol (TCHOL) and low-density lipoprotein cholesterol (LDL-C), while males had high mean values for high-density lipoprotein cholesterol (HDL-C), triglycerides (TG), systolic blood pressure (SBP) and diastolic blood pressure (DBP). No signiļ¬cant age and gender differences were observed for dietary intake. Signiļ¬cantly more females (51.9%) presented with increased WC than males (4.6%). Participants who had a high dietary energy intake were signiļ¬cantly less likely to present with larger WC (OR: 0.250 95% CI [0.161; 0.389]), low HDL-C (OR: 0.306 95% CI [0.220; 0.425]) and high LDL-C (OR: 0.583 95% CI [0.418; 0.812]) but more likely to present with elevated FBG (OR: 1.01 95% CI [0.735; 1.386]), high TCHOL (OR: 1.039 95% CI [0.575; 1.337]), high TG (OR: 1.186 95% CI [0.695; 2.023]) and hypertension (OR: 5.205 95% CI [3.156; 8.585]). After adjusting for age, gender, smoking, and alcohol status, high energy intake was more than two times likely to predict MetS in adults with a large WC (OR: 2.766 95% CI [0.863; 3.477] and elevated FBG (OR: 2.227 95% CI [1.051; 3.328]). Therefore, identifying groups that are at an increased risk and those that are in their early stages of MetS will help improve and prevent the increase of the MetS in the future

    Skills training for Civil Technology learners in South African schools, is an aspect entrenched in the Civil Technology policy document in order to produce skilled personnel for a sustainable economy. Practical activities through the Practical Assessment Task (PAT) are national requirements for all practical-based subjects from grades 10ā€“12 in South African schools. The purpose of this study was to investigate the status of Civil Technology practical activities in three South African schools in the Eastern Cape Province. Purposive sampling was used to identify 41 learners and 3 teachers to participate in the study. Questionnaires, semi-structured interviews and observation as data collection methods were instruments used to collect data. The study has found that learners exit grade 12 without basic practical hands-on skills. Civil Technology practical activities were found to be inadequately offered in the three schools investigated. Educators should be well-trained by higher education institutions (HEIs) to conduct practical activities with learners so that these learners are equipped with marketable skills in order to contribute to a sustainable economy after grade 12. Technology teacher education and training should include regular exposure and visits to relevant industries in order for teachers to keep abreast with the latest technological developments. The supply of equipment to schools should be coupled with routine maintenance of the equipment.https://doi.org/10.4102/td.v10i3.18

    OBJECTIVES: To determine whether subclinical vitamin D deficiency in Indian children under 5 y of age is a risk factor for severe acute lower respiratory infection (ALRI). DESIGN: A hospital-based case-control study. SETTING: Sanjeevani Paediatrics Hospital, a private hospital in Indapur, India. PARTICIPANTS: A total of 150 children including 80 cases and 70 controls, aged 2-60 months, were enrolled. Case definition of severe ALRI as given by the World Health Organization was used for cases. Controls were healthy children attending outpatients' service for immunization. MAIN OUTCOME MEASURE: Association of serum 25-hydroxyvitamin D3 (25OHD3) with severe ALRI, controlling for demographic and other potential risk factors. RESULTS: Serum 25OHD3 increased with age. Factors significantly associated with decreased risk of severe ALRI in univariate analysis were: exclusive breastfeeding in the first 4 months (cases 35/78 (45%), controls 41/64 (64%); P=0.02); introduction of other dietary liquids than milk only after 6 months (cases 46/70 (66%), controls 31/66 (47%); P=0.03); use of liquid petroleum cooking fuel (cases 32/80 (40%), controls 40/70 (57%); P=0.04); infant not covered in swaddling cloths when exposed to sunlight before crawling (cases 11/52 (21%), controls 25/54 (46%); P=0.006); and serum 25OHD3>22.5 nmol/l (cases 16/80 (20%), controls 48/70 (69%); P22.5 nmol/l (OR: 0.09; 95% CI 0.03-0.24; P<0.001) and exclusive breastfeeding in the first 4 months of life (OR 0.42; 95% CI 0.18-0.99; P=0.046) with age and height/age as significant covariates. CONCLUSION: Subclinical vitamin D deficiency and nonexclusive breastfeeding in the first 4 months of life were significant risk factors for severe ALRI in Indian children
