Comparison of a Web-Based Dietary Assessment Tool with Software for the Evaluation of Dietary Records

Background

Dietary assessment in clinical practice is performed by means of computer support, either in the form of a web-based tool or software. The aim of the paper is to present the results of the comparison of a Slovenian web-based tool with German software for the evaluation of four-day weighted paper-and-pencil-based dietary records (paper-DRs) in pregnant women.

Methods

A volunteer group of pregnant women (n=63) completed paper-DRs. These records were entered by an experienced research dietitian into a web-based application (Open Platform for Clinical Nutrition, OPEN, http://opkp.si/en, Ljubljana, Slovenia) and software application (Prodi 5.7 Expert plus, Nutri-Science, Stuttgart, Germany, 2011). The results for calculated energy intake, as well as 45 macro- and micronutrient intakes, were statistically compared by using the non-parametric Spearman’s rank correlation coefficient. The cut-off for Spearman’s rho was set at >0.600.

Results

12 nutritional parameters (energy, carbohydrates, fat, protein, water, potassium, calcium, phosphorus, dietary fiber, vitamin C, folic acid, and stearic acid) were in high correlation (>0.800), 18 in moderate (0.600–0.799), 11 in weak correlation (0.400–0.599), while 5 (arachidonic acid, niacin, alpha-linolenic acid, fluoride, total sugars) did not show any statistical correlation.

Conclusion

Comparison of the results of the evaluation of dietary records using a web-based dietary assessment tool with those using software shows that there is a high correlation for energy and macronutrient content.     

CASE STUDIES OF THE TREATMENT OF HYPOTHYROIDISM BY MERIDIAN THEORY OF CHINESE MEDICINE

Some patients with hypothyroidism still remain symptom after prolonged treatment with thyroxine. Alternative treatment needs to be explored. The treatment is described as overlapof acupunture, supplemented with electric acupuncture, magnetic acupuncture, ear acupuncture, herbaltreatment, and acupressure of thyroid. The result of two case studies will be discussed in the presentation.The theoretical basis for the approach will also be explored.In Chinese medicine, hypothyroidismis often defined as spleen deficiency in the early stage and can be treated with ISRQ recipes (Invigorating the Spleen and Replenishing the Qi). In the chronic stage, hypothyroidism can be seen as kidneydeficiency and can be treated with KRR (Kidney Reinforcing Regimen). Hypthyroidism symptoms aresometimes diffcult to treat. However, TCM (Traditional Chinese Medicine) diagnosis and treatmentare based on an overall analysis of the illness according to patients' condition. After successful treamentof TCM, patients can stop taking Thy     

The opportunities and shortcomings of using big data and national databases for sarcoma research

The rarity and heterogeneity of sarcomas make performing appropriately powered studies challenging and magnify the significance of large databases in sarcoma research. Established large tumor registries and population-based databases have become increasingly relevant for answering clinical questions regarding sarcoma incidence, treatment patterns, and outcomes. However, the validity of large databases has been questioned and scrutinized because of the inaccuracy and wide variability of coding practices and the absence of clinically relevant variables. In addition, the utilization of large databases for the study of rare cancers such as sarcoma may be particularly challenging because of the known limitations of administrative data and poor overall data quality. Currently, there are several large national cancer databases, including the Surveillance, Epidemiology, and End Results database, the National Cancer Data Base of the American College of Surgeons and the American Cancer Society, and the National Program of Cancer Registries of the Centers for Disease Control and Prevention. These databases are often used for sarcoma research, but they are limited by their dependence on administrative or billing data, the lack of agreement between chart abstractors on diagnosis codes, and the use of preexisting documented hospital diagnosis codes for tumor registries, which lead to a significant underestimation of sarcomas in large data sets. Current and future initiatives to improve databases and big data applications for sarcoma research include increasing the utilization of sarcoma-specific registries and encouraging national initiatives to expand on real-world, evidence-based data sets.     

Computer usage among nurses in rural health-care facilities in South Africa: obstacles and challenges

Aims This study discusses factors inhibiting computer usage for work-related tasks among computer-literate professional nurses within rural healthcare facilities in South Africa. Background In the past two decades computer literacy courses have not been part of the nursing curricula. Computer courses are offered by the State Information Technology Agency. Despite this, there seems to be limited use of computers by professional nurses in the rural context. Methods Focus group interviews held with 40 professional nurses from three government hospitals in northern KwaZulu-Natal. Results Contributing factors were found to be lack of information technology infrastructure, restricted access to computers and deficits in regard to the technical and nursing management support. The physical location of computers within the health-care facilities and lack of relevant software emerged as specific obstacles to usage. Conclusion Provision of continuous and active support from nursing management could positively influence computer usage among professional nurses. A closer integration of information technology and computer literacy skills into existing nursing curricula would foster a positive attitude towards computer usage through early exposure. Implications for nursing management Responses indicated that change of mindset may be needed on the part of nursing management so that they begin to actively promote ready access to computers as a means of creating greater professionalism and collegiality.
