RESUMO
The dilution of commercial broiler feed with copra meal (CM), palm kernel meal (PKM) and cassava leaf meal (CLM) and enzyme supplementation was investigated. Two hundred and eighty 7-day old Cobb 500 broilers were fed commercial feed alone or diluted with the test ingredients with and without enzyme. There were no interaction effects (p>0.05) on feed intake (FI) and weight gain (WG). Poorer (p<0.05) feed conversion ratio (FCR) was observed on the diet diluted diets from 22-42 d, but this was restored (p>0.05) by enzyme supplementation. There was no interaction effect on final body weight (FBW). Diet dilution depressed FBW (p<0.05) but enzyme supplementation restored (p>0.05) this weight depression. Abdominal fat was lighter (p<0.05) on CLM compared to CM. There were no interaction effects (p>0.05) on the weight of gut segments and E. coli count. Heavier (p<0.05) liver, gizzard and intestine were observed on the test diets. Commercial feed dilution with CM, CLM and PKM at 100 g/kg for starter and 200 g/kg for finisher would be a viable option for smallholder broiler production. More research is needed into dilution levels and enzyme concentrations.(AU)

BACKGROUNDMore than 80% of deaths from cardiovascular disease are estimated to occur inlow-income and middle-income countries, but the reasons are unknown.METHODSWe enrolled 156,424 persons from 628 urban and rural communities in 17 countries(3 high-income, 10 middle-income, and 4 low-income countries) and assessedtheir cardiovascular risk using the INTERHEART Risk Score, a validated score forquantifying risk-factor burden without the use of laboratory testing (with higherscores indicating greater risk-factor burden). Participants were followed for incidentcardiovascular disease and death for a mean of 4.1 years.RESULTSThe mean INTERHEART Risk Score was highest in high-income countries, intermediatein middle-income countries, and lowest in low-income countries (P<0.001).However, the rates of major cardiovascular events (death from cardiovascularcauses, myocardial infarction, stroke, or heart failure) were lower in high-incomecountries than in middle- and low-income countries (3.99 events per 1000 personyearsvs. 5.38 and 6.43 events per 1000 person-years, respectively; P<0.001). Casefatality rates were also lowest in high-income countries (6.5%, 15.9%, and 17.3%in high-, middle-, and low-income countries, respectively; P = 0.01). Urban communitieshad a higher risk-factor burden than rural communities but lower ratesof cardiovascular events (4.83 vs. 6.25 events per 1000 person-years, P<0.001) andcase fatality rates (13.52% vs. 17.25%, P<0.001). The use of preventive medicationsand revascularization procedures was significantly more common in high-incomecountries than in middle- or low-income countries (P<0.001).CONCLUSIONSAlthough the risk-factor burden was lowest in low-income countries, the rates ofmajor cardiovascular disease and death were substantially higher in low-incomecountries than in high-income countries. The high burden of risk factors in highincome...

AIMS: In an international prospective cohort study we assessed the relationship between glucose levels and incident cardiovascular events and death. METHODS AND RESULTS: 18,990 men and women were screened for entry into the DREAM clinical trial from 21 different countries. All had clinical and biochemical information collected at baseline, including an oral glucose tolerance test (OGTT), and were prospectively followed over a median (IQR) of 3.5 (3.0-4.0) years for incident cardiovascular (CV) events including coronary artery disease (CAD), stroke, congestive heart failure (CHF) requiring hospitalization, and death. After OGTT screening, 8000 subjects were classified as normoglycaemic, 8427 had impaired fasting glucose (IFG) or impaired glucose tolerance (IGT), and 2563 subjects had newly diagnosed type 2 diabetes mellitus (DM). There were incident events in 491 individuals: 282 CAD, 54 strokes, 19 CHF, and 164 died. The annualized CV or death event rate was 0.79/100 person-years in the overall cohort, 0.51/100 person-years in normoglycaemics, 0.92/100 person-years among subjects with IFG and/or IGT at baseline, and 1.27/100 person-years among those with DM (p for trend <0.0001). Among all subjects, a 1 mmol/l increase in fasting plasma glucose (FPG) or a 2.52 mmol/l increase in the 2-h post-OGTT glucose was associated with a hazard ratio increase in the risk of CV events or death of 1.17 (95% CI 1.13-1.22). CONCLUSIONS: In this large multiethnic cohort, the risk of CV events or death increased progressively among individuals who were normoglycaemic, IFG or IGT, and newly diagnosed diabetics. A 1 mmol/l increase in FPG was associated with a 17% increase in the risk of future CV events or death. Therapeutic or behavioural interventions designed to either prevent glucose levels from rising, or lower glucose among individuals with dysglycaemia should be evaluated.

The clinical course and follow-up of 14 neonates who developed acute renal failure are reported. Renal failure in these patients was secondary to major perinatal disorders, e.g., hyaline membrane disease, pneumonia, hemorrhage, or sepsis. Thirteen patients had hypoxia and nine were in shock when renal failure developed. Five patients died during the acute stage of renal failure. Of nine survivors, five patients sustained residual renal damage.
