Burden of non-communicable diseases and the achievement of the sustainable development goals in 2030 in Mercosur countries.

OBJECTIVES: The aims of this article were to analyse the burden of NCDs and their RFs in the Mercosur countries between 1990 and 2019 and to project mortality trends for 2030. STUDY DESIGN: Epidemiological study of time series. METHODS: The present study used data from the Global Burden of Disease study. The absolute number of deaths, mortality rates, disability-adjusted life years, years of life lost, years lived with disability and the burden of premature mortality by NCD attributable to the RFs were evaluated. Projections were made up to 2030. Age-standardised rates were used to draw comparisons by years and by countries. The analysis was conducted using the RStudio software. RESULTS: Between 1990 and 2019, a decrease was found in the premature mortality rates caused by NCDs in all the countries, except for Paraguay, which remained stable. When analysing premature mortality rates due to NCDs up to 2030, it was predicted that none of the countries would achieve the sustainable development goal of a one-third reduction in premature mortality by NCDs. Regarding the impacts of the RFs for NCDs, smoking, dietary risks, high blood pressure (BP) and high body mass index (BMI) were the main risks attributable to premature deaths due to NCDs. CONCLUSIONS: The results showed that mortality rates are declining in Mercosur countries; however, none of the countries are predicted to achieve the sustainable development goal of a one-third reduction in mortality due to NCDs by 2030. In addition to access to adequate treatment, progress is required in public regulation actions to reduce RFs, such as smoking, dietary risks, high BP and high BMI.

An isolate of the nematophagous fungus Monacrosporium thaumasium for the control of cattle trichostrongyles in south-eastern Brazil.

A mycelial formulation in sodium alginate pellets of the nematophagous fungus Monacrosporium thaumasium (isolate NF34A) was assessed in the biological control of beef cattle trichostrongyles in tropical Brazil. Two groups of ten male Nellore calves aged 6 months, a fungus-treated group and a control group, were fed on a pasture of Brachiaria decumbens naturally infected with larvae of cattle trichostrongyles. The fungus-treated group received doses of sodium alginate mycelial pellets orally (1 g pellets (0.2 g fungus)/10 kg live weight) twice a week for 12 months. At the end of the study there was a significant reduction (P< 0.01) in the number of eggs per gram of faeces and coprocultures of the fungus-treated group--47.8% and 50.2%, respectively--in relation to the control group. There was a 47.3% reduction in herbage samples, collected up to 0-20 cm from faecal pats, between the fungus-treated and control groups, and a 58% reduction when the sampling distance was 20-40 cm from faecal pats (P< 0.01). The treatment with sodium alginate pellets containing the nematode-trapping fungus M. thaumasium reduced trichostrongyles in tropical south-eastern Brazil and could be an effective tool for the biological control of this parasitic nematode in beef cattle. However, in such a tropical climate with low rainfall the fungal viability can be reduced.

Comparison between the action of nematode predatory fungi Duddingtonia flagrans and Monacrosporium thaumasium in the biological control of bovine gastrointestinal nematodiasis in tropical southeastern Brazil.

Sodium alginate pellets of the nematode predatory fungi Duddingtonia flagrans and Monacrosporium thaumasium were evaluated in the biological control of bovine gastrointestinal nematodiasis. Three groups (A-C) of ten six month old male Nelore bulls were kept in paddocks of Brachiaria decumbens for 12 months. Each animal of group A received 1g/10 kg of body weight (b.w.) of pellets of D. flagrans (0.2 g of fungus/10 kg b.w.) and of group B, 1g/10 kg of b.w. of pellets of M. thaumasium (0.2 g of fungus/10 kg b.w.), twice a week, for 12 months. Animals of the group control received no fungus. The monthly averages of egg count per gram of feces of the animals of groups A and B were 56.67% and 47.8% smaller, than the animals of group C (p<0.05), respectively. Treatment of bulls with pellets containing the nematophagous fungi D. flagrans and M. thaumasium can be used as an alternative treatment of bovine gastrointestinal nematodiasis, however, D. flagrans was more efficient than M. thaumasium for the biological control in the environmental conditions of the present study.

Clonal monosomy of chromosome 21 in a case of myelodysplastic syndrome.

This study reports on a cytogenetic finding in a bone marrow examination of a 47-year-old male patient treated in the Hematology and Blood Transfusion Service of the Hospital de Base in São José do Rio Preto, São Paulo State, Brazil. The only alteration found at diagnosis of myelodysplastic syndrome (MDS) subtype refractory anemia with excess blasts (RAEB-2) was clonal monosomy of chromosome 21. The patient evolved to acute myeloid leukemia type M2 and died nine months after diagnosis. Clonal monosomy of chromosome 21, as the only cytogenetic abnormality in MDS, has only been reported three times previously. This uncommon cytogenetic abnormality in MDS has been associated with a poor clinical course, although more data will be needed to determine if this prognosis is invariable.

Diuretic activity and acute oral toxicity of Palicourea coriacea (Cham.) K Schum.

AIM OF THE STUDY: Palicourea coriacea (Cham.) K Schum, is an endemic plant used in the Midwestern Region of Brazil, popularly known as "douradinha do campo" and "congonha do campo". This plant has been used in traditional medicine for several ailments, especially to treat kidney diseases. Since no formal studies on the biological activities and medicinal properties of the ethanolic extract of Palicourea coriacea (PCEE) have been carried out previously, the present study represents the first research into the efficacy of this plant as a diuretic agent employing laboratory rats as test animals. MATERIALS AND METHODS: For diuretic activity evaluation we assayed three doses of PCEE (20, 40 and 80mg/kg) and measurement of the urinary volume and electrolytes (Na(+), K(+)) concentration were taken. The acute oral toxicity of PCEE was investigated according to OECD Guideline 423. RESULTS: The oral administration of a single dose of PCEE significantly increased the urinary volume in 24h. Additionally, the treatment with PCEE increased, in a dose-dependent manner, the excretion of both, Na(+) and K(+). No sign of toxicity was observed in the animals. CONCLUSIONS: The present study confirmed the ethnopharmacological use of Palicourea coriacea as a diuretic agent in the experimental condition tested here. Additionally, this work supports the importance of the preservation of local knowledge as well as the conservation of Brazilian biodiversity.

Anti-inflammatory activity of oleoresin from Brazilian Copaifera.

The oleoresin from Brazilian Copaifera species yielded copalic acid and sesquiterpenes and showed marked anti-inflammatory activity using various experimental models in rats. The oleoresin significantly inhibited carrageenin-induced pedal edema following oral doses from 0.70 to 2.69 ml/kg, but was somewhat less effective than 50 mg/kg calcium phenylbutazone. Repeated administration of the oleoresin at a dose of 1.26 ml/kg for a 6-day period reduced granuloma formation with a response comparable to that of 20 mg/kg of calcium phenylbutazone. This same dose of oleoresin also reduced the vascular permeability to intracutaneous histamine. The LD50 value of the oleoresin in rats was estimated to be 3.79 (3.21-4.47) ml/kg.
