BACKGROUND: It is commonly stated that risk factors for postoperative nausea are the same as for vomiting. The authors designed a prospective study to identify and differentiate the risk factors for postoperative nausea and vomiting in various surgical populations in a clinical audit setting. METHODS: The study included 671 consecutive surgical inpatients, aged 15 yr or more, undergoing various procedures. The study focused on postoperative nausea visual analog scale scores every 4 h and vomiting episodes within 72 h. Both vomiting and retching were considered as emetic events. Patient-, anesthesia-, and surgery-related variables that were considered to have a possible effect on the proportion of patients experiencing postoperative nausea and/or vomiting were examined. The bivariate Dale model for binary correlated outcomes was used to identify selectively the potential risk factors of postoperative nausea and vomiting. RESULTS: Among the 671 patients in the study, 126 (19%) reported one or more episodes of nausea, and 66 patients (10%) suffered one or more emetic episodes during the studied period. There was a highly significant association between the two outcomes. Some risk factors were predictive of both nausea and vomiting (female gender, nonsmoking status, and general anesthesia). History of migraine and type of surgery were mainly responsible for nausea but not for vomiting. The predictive effect of risk factors was controlled for postoperative pain and analgesic drugs. CONCLUSION: This study shows that differences exist in risk factors of postoperative nausea and vomiting. These could be explained by differences in the physiopathology of the two symptoms. [less ▲]

BACKGROUND: Sex differences in the effects of genetic and environmental factors on circulating lipids have been examined mainly in adults, in whom the influences of sex steroid hormones are well known. OBJECTIVE: Our objective was to determine the effect of sex on genetic and environmental influences on serum lipids in prepubertal boys and girls. DESIGN: Children aged 6-8, 8-10, and 10-12 y (n = 1028) were selected at random in the Belgian province of Luxembourg, a region in Europe with a high prevalence of risk factors for cardiovascular disease and diabetes. Blood glucose and serum cholesterol, triacylglycerol, and insulin concentrations were measured, and anthropometric data and blood pressure were recorded. Familial data were obtained from standardized questionnaires. Nutritional status was obtained from a 3-d record. Participation was 70.3% of the primary cohort. RESULTS: Cholesterol, triacylglycerol, and insulin values were among the highest recorded in studies of children. In girls, cholesterol correlated positively with the energy density of intake of saturated fat (r = 0.13, P = 0.001), cholesterol (r = 0.11, P = 0.006), and protein (r = 0.12, P = 0.007) and negatively with the ratio of polyunsaturated to saturated fat intake (r = -0.14, P = 0.001) and the energy density of carbohydrate intake (r = -0.11, P = 0.019). In boys, no such relations were found. Triacylglycerol was not significantly related to nutritional factors. Consistent, independent relations were found between reported elevated cholesterol concentrations in the parental and grandparental generation and cholesterol (r = 0.101, P = 0.011) and triacylglycerol (r = 0.09, P = 0.03) in boys. No such associations were found in girls. CONCLUSION: Environmental and genetic factors may have different effects on serum cholesterol in girls and boys. [less ▲]

Indigestible carbohydrate (CHO) composition can vary markedly between barley varieties. They induce changes in intestinal ecophysiology and enhance growth of health-promoting bacteria. An experiment was undertaken to assess whether these changes could influence Salmonella typhimurium (ST) infection in pigs and transmission between penmates. A challenge study was undertaken using 84 recently weaned piglets divided in 12 pens, and fed one of the 4 experimental diets (3 pens/diet), according to the barley variety. Three hullless and one hulled varieties were chosen according to their differing CHO composition (amylose/amylopectin, β-glucan, and insoluble non-starch polysaccharides). After 14 d of adaptation, 2 pigs per pen (Trojan pigs, TrojP) were orally infected (8.0 log cfu/animal) with a low virulent, nalidixic acid and novobiocin resistant ST strain. The other animals were considered as Contact pigs (ConP) to assess ST transmission. Over 5 d following inoculation, pigs were monitored for detection of ST in the feces using plate counts. On d 6, 2 TrojP and 2 ConP per group were killed and intestinal samples as well as organ samples (liver, spleen, and lymph nodes) were analyzed for ST. The results showed that in TrojP, the cereal variety had no influence on ST fecal shedding over time and gastrointestinal tract (GIT) colonization. All pigs were positively tested for ST. Translocation of ST to lymph nodes was observed frequently but not to other organs. In ConP, compared with hulled barley, hulless barleys reduced the number of animals shedding ST (P < 0.05 for d 2) and the number of ST (cfu/g) in cecum on d 6 (P < 0.01). Although hulless barleys did not protect against colonization when directly challenged at a high oral dose, these barleys may be useful to reduce natural ST transmission among penmates. [less ▲]

In the late 1980s, a new hypervirulent and epidemic form of bovine viral diarrhoea virus (BVDV) infection appeared in North America. A similar but sporadic syndrome was later reported in Europe. To compare the pathogenic characters of the North American and European hypervirulent strains, we inoculated BVDV naive calves with BVDV strains isolated from haemorrhagic syndromes originating in Belgium, France and the USA. The experimental procedure comprised daily clinical examination and measurement of blood and virological parameters.The American BVD890/256 strain induced severe thrombocytopaenia, profuse diarrhoea and pneumonia in all calves, indicating that hypervirulent BVDV could be the primary infectious agent of pneumonia. Interestingly, a strong correlation was observed between the intense viraemia and a decreased platelet count. None of the European strains tested induced significant pathological signs, although isolated from cases presenting haemorrhagic syndrome. [less ▲]

Studies on chemical ecology of host plant selection by herbivores were largely carried out to explain the diversity of secondary plant chemicals and host specialisation of herbivores. The glucosinolate – isothiocyanate system in Brassicaceae plants was considered as a plant defence and was known to influence the feeding behaviour of phytophagous insects such as the cabbage aphid, Brevicoryne brassicae. Purified myrosinases from the latter and from white mustard, Sinapis alba, were used to hydrolyse two glucosinolate compounds. Identification of the degradation products, mainly isothiocyanates, was performed by gas chromatography – mass spectrometry. While sinigrin hydrolysis gave identical isothiocyanates for insect and plant enzymes, B. brassicae myrosinase showed a particular activity toward sinalbin. A lost of an hydroxy group was observed for the two latter substrates related products when compared to the S. alba enzymatic specificity. Aphid and plant myrosinases have different properties and specificities which can be discussed in relation to a co-evolution approach. [less ▲]
