Work-related psychological health among clergywomen in Australia

Drawing on the classic model of balanced affect, the Francis Burnout Inventory conceptualises good work-related psychological health among clergy in terms of negative affect being balanced by positive affect. This paper sets out to explore the relationship between work-related psychological health and psychological type (as assessed by the Francis Psychological-Type Scales) among a sample of 212 Australian clergywomen who completed the National Church Life Survey Form L in 2006. The data supported the internal consistency reliability of the Francis Burnout Inventory and Francis Psychological-Type Scales and found that work-related psychological health was positively related to extraversion and sensing

Paediatric gastroenterology evaluation of overweight and obese children referred from primary care for suspected non-alcoholic fatty liver disease.

BackgroundScreening overweight and obese children for non-alcoholic fatty liver disease (NAFLD) is recommended by paediatric and endocrinology societies. However, gastroenterology societies have called for more data before making a formal recommendation.AimTo determine whether the detection of suspected NAFLD in overweight and obese children through screening in primary care and referral to paediatric gastroenterology resulted in a correct diagnosis of NAFLD.MethodsInformation generated in the clinical evaluation of 347 children identified with suspected NAFLD through screening in primary care and referral to paediatric gastroenterology was captured prospectively. Diagnostic outcomes were reported. The diagnostic performance of two times the upper limit of normal (ULN) for alanine aminotransferase (ALT) was assessed.ResultsNon-alcoholic fatty liver disease was diagnosed in 55% of children identified by screening and referral. Liver disease other than NAFLD was present in 18% of those referred. Autoimmune hepatitis was the most common alternative diagnosis. Children with NAFLD had significantly (P < 0.05) higher screening ALT (98 ± 95) than children with liver disease other than NAFLD (86 ± 74). Advanced fibrosis was present in 11% of children. For the diagnosis of NAFLD, screening ALT two times the clinical ULN had a sensitivity of 57% and a specificity of 71%.ConclusionsScreening of overweight and obese children in primary care for NAFLD with referral to paediatric gastroenterology has the potential to identify clinically relevant liver pathology. Consensus is needed on how to value the risk and rewards of screening and referral, to identify children with liver disease in the most appropriate manner

Blood pressure profile in Nigerian children

Objective: To observe blood pressure (BP) pattern and its correlates in primary school children of northern Nigeria.Design: Sitting BP and pulse were measured in quadruplicate, then repeated after four weeks in 1,721 healthy children aged five to 16 years. Body weight and height were also measured in their school environment.Setting: Primary schools located in three communities in Zaria Local Government Area (LGA) of Kaduna State, Nigeria. The communities were Tudun Wada (University community of migrants with some indigenous Hausa settlers), Zaria City (traditional Hausa community) and Zaria Kewaye (a rural Hausa settlement).Results: BP rose with age. However, BP levels particularly systolic was highest in children from Tudun Wada (TW) (urban), followed by those from Zaria city (ZC) (semi urban), and Zaria Kewaye (ZK) (rural). The mean systolic/diastolic BP (mmHg) were: 99/61, 94/62 and89/60 in children aged five to ten years; and 112/69, 109/68 and 107/68 in those older than 10 years respectively. The differences in BP levels were evident even as early as the age of five years and appears largely independent of physical stature and gender.Conclusion: These observations suggest that place of residence and ethnicity may be important factors in the progression of BP with age in some children in northern Nigeria

Medicinal plant use of villagers in the Mopani district, Limpopo province, South Africa

Background: An ethno-medical survey of plants was conducted at Mashishimale village near Phalaborwa, in Limpopo Province (South Africa). Owing to high level of poverty and lack of proper daily operational healthcare facilities in certain parts of Mashishimale village, the use of plants as medicine persists. The aim of the study was to compile a list of medicinal plants used by traditional health practitioners for treatment of diabetes mellitus and other ailments.Materials and methods: Traditional health practitioners were identified using the snowballing sampling technique. Structured interviews were conducted and a list of medicinal plants compiled. Data collection included local names of the plants, the plant parts used in the traditional medicine, the disease treated by the plant-based remedies and the method of preparation of the medicines.Results and discussion: A total of 49 plants species belonging to 20 different families we identified. Plant parts used in preparation of remedies by practitioners are roots (51%), stem barks (30%) and leaves (19%). The most preferred methods of administration were boiling (74%) and infusion (12%). About 14 plants species were indicated for treatment of diabetes mellitus, while most plant species were indicated for sexually transmitted diseases, fertility and erectile dysfunction.Conclusion: The results of the survey indicate that plants play a significant role in primary healthcare of the community of Mashishimale Village. It would seem that a number of major diseases/ailments are treated by traditional methods. Scientific investigation is therefore needed to isolate active compounds and to determine safe dosages for treatment. These studies may guide the regulation of herbal medicine industry in South Africa.Key words: Ethnobotanical, Medicinal plants, Mashishimale villag

Aloe arborescens aqueous gel extract alters the activities of key hepatic enzymes and blood concentration of triglycerides, glucose and insulin in alloxan-induced diabetic rats

The present study investigated the antidiabetic activity and the possible mechanisms of action of aqueous extract of Aloe arborescens leaf gel (AALGEt) on normal and alloxan-induced diabetic rats. Diabetes was induced in 12 h fasted rats by intraperitoneal injection of 140 mg/kg body weight of alloxan. Blood glucose levels, body weight and water intake were determined on day 7, 14 and 21 of AALGEt treatment. Plasma insulin and triglycerides levels, as well as activities of hepatic glucokinase and glucose 6-phosphatase (G6Pase) were determined at the end of the study. Blood glucose levels, plasma triglyceride and insulin levels, as well as the activity of hepatic G6Pase were significantly increased in diabetic rats. With the exception of hepatic glucokinase activity, daily oral administration of AALGEt to diabetic rats significantly reversed the effects induced by alloxan. The activities of glucokinase and glucose-6-phosphatase as well as plasma insulin levels in AALGEt-treated normal rats were comparable with those observed in untreated normal rats. The results suggest that AALGEt ameliorates physiological parameters altered by the diabetic state. These effects may be mediated in part, through the protection of pancreatic beta cells from further damage by alloxan.Keywords: Aloe arborescens, alloxan, diabetic rats, antidiabetic activity, hepatic enzymes

Radical scavenging activity of selected medicinal plants from Limpopo Province of South Africa

Plants collected from Limpopo province of South Africa were investigated for their antioxidative potential using the DPPH radical scavenging assay. Acetone extracts of Flueggea virosa had the highest antioxidant activity with an IC50 value of 30 ìg/ml, closely matching the ascorbic acid with an IC50 value of 25 ìg/ml. The lowest antioxidant readings were observed with extracts of Rhynchosia venulosa (root extract) and Ficus ingens (leaf extract). Acetone extract of Bridelia virosa leaves had the highest phenolic content (156 mg GAE/g extract), while the lowest content was recorded for R. venulosa root extract and leaf extract of F. ingens (8.3 and 17.7 mg GAE/g extract, respectively). There was a linear correlation between antioxidant activityand total phenolic content. Extracts with high phenolic content had low IC50 values, while extracts with low phenolic concentrations had high IC50 values

Solving multi-scale low frequency electromagnetic problems

In this paper, we will discuss two methods to tackle the low-frequency, multi-scale electromagnetics problem. First we will discuss the augmented electric field integral equation (AEFIE), and then, we will discuss the equivalence principle algorithm (EPA). The AEFIE allows the solution of such problems without the need to perform a loop search of a complex structure. The EPA allows the separation of circuit physics from wave physics in a multiscale problem. Hybridization of these two methods will be discussed.published_or_final_versionThe 4th European Conference on Antennas and Propagation (EuCAP) 2010, Barcelona, Spain, 12-16 April 2010.
