Assessment of blood and productive parameters in mid-lactation dairy cows fed different diets: replacement of corn silage with triticale silage.

Corn crops require large amounts of resources that affect the environmental sustainability of dairy cow farming systems. The aim of the study was thus to investigate the effects of the replacement of corn silage (CS) with triticale silage (TS) by evaluating blood and productive parameters. The study lasted 7 weeks and involved two groups of 20 Italian Holstein Friesian dairy cows that were homogeneous in terms of parity ( 3 ± 1.5 ), days in milk (DIM) ( 150 ± 85.0 ), and daily milk production ( 26 ± 4.6  kg). Chemical analysis of feeds was carried out weekly. Dry-matter intake was estimated daily. At the beginning and end of the trial, haematological, metabolic, and immunological parameters were analysed. At the same, time body weight and body condition score were measured. Milk characteristics were also analysed weekly. Statistical analysis was performed by ANOVA on data of the second sampling, and a non-parametric test was performed to analyse BCS. Regarding the haematological parameters in the two groups, only lymphocyte values were not in the normal range (2.86 and 2.50 × 10 9  L for CS and TS, respectively). Metabolic parameters were in the normal range except for blood ureic nitrogen (BUN; 13.65 and 14.04  mg dL - 1 ), non-esterified fatty acids (NEFAs; 21.40 and 31.93  µ mol L - 1 ), and Cl (91.99 and 93.50  mmol L - 1 ). Hair cortisol was low (0.94 and 0.91  pg mg - 1 ), indicating the absence of stress signs, as confirmed by the results of other immunological parameters (serum lysozyme (SL), bactericidal activity (SBA), haptoglobin (HP), and oxygen free radicals (OFRs)). Statistical differences were not found either for haematological or biochemical parameters. The total replacement of CS with TS did not affect milk yield and composition. In conclusion, the replacement of CS by TS did not give rise to significant modifications in the parameters investigated and did not alter the health status of the animals, thus suggesting the feasibility of its introduction into the diet of mid-lactation dairy cows.

Late onset multiple sclerosis: concerns in aging patients.

Late onset multiple sclerosis (LOMS) is when the first symptom starts after 50 years of age, representing 4.5% of multiple sclerosis (MS) patients. This study describes the clinical characteristics of patients with LOMS followed at a specialized MS center in São Paulo. Data was obtained from medical records of 742 patients with MS. The LOMS frequency was 4.18%, median age at onset was 54 years and the predominant disease course was primary progressive (64.3%). The patients reached the disability landmarks of EDSS grades 3.0, 6.0 and 7.0 in the following proportion and time: EDSS 3.0: 77.42% of patients in 3.7 years; EDSS 6.0: 58.06% in 5.1 years and EDSS 7.0: 32.26% in 5.7 years. The comparative analysis with a matched control group of patients with early onset MS showed that late onset, associated with a progressive course, were predictors of reaching EDSS 3.0 and 6.0 in a shorter time.

ABSTRACT Late onset multiple sclerosis (LOMS) is when the first symptom starts after 50 years of age, representing 4.5% of multiple sclerosis (MS) patients.

The LOMS frequency was 4.18%, median age at onset was 54 years and the predominant disease course was primary progressive (64.3%). The patients reached the disability landmarks of EDSS grades 3.0, 6.0 and 7.0 in the following proportion and time: EDSS 3.0: 77.42% of patients in 3.7 years; EDSS 6.0: 58.06% in 5.1 years and EDSS 7.0: 32.26% in 5.7 years.

RESUMO Esclerose múltipla de inicio tardio (EMIT) caracteriza-se pelo início de sintomas aos 50 ou mais anos de idade, representando 4,5% dos pacientes com esclerose múltipla (EM). Este estudo descreve as características clínicas de pacientes com EMIT acompanhados num centro de EM em São Paulo. Dados foram obtidos através de análise de prontuário de 742 pacientes com EM. A frequência de EMIT foi de 4,18%, a mediana da idade de início foi de 54 anos e a forma clínica predominante a primariamente progressiva (64,3%). Os pacientes atingiram os marcos de incapacidade EDSS 3, 6 e 7 nas respectivas proporções e tempo: EDSS 3.0, 77,42% de pacientes em 3.7 anos; EDSS 6.0, 58,06% em 5.1 anos e EDSS 7.0, 32,26% em 5.7 anos. A análise comparativa a um grupo controle de jovens com EM, mostrou que o início tardio associado a forma primariamente progressiva foram preditores para atingir EDSS 3 e 6 num período menor.

The profile of patients followed at the Neuroimmunology Clinic at UNIFESP: 20 years analysis.

OBJECTIVE: To describe the clinical activities at the Neuroimmunology Clinic of the Universidade Federal de São Paulo (UNIFESP) from 1994 to 2013. METHOD: The final diagnosis of all patients that attended the center was reviewed and established upon specific guidelines for each disease. The number of total appointments and extra clinical activities (reports and prescriptions) were also analyzed, as are part of routine activities. RESULTS: 1,599 patients attended the Clinic from 1994 to 2013: 816 with multiple sclerosis (MS), 172 with clinical isolated syndromes, 178 with neuromyelitis optica (NMO), 216 with other demyelinating disease, 20 with metabolic disorder, 42 with a vascular disease and 155 with other or undetermined diagnosis. A mean 219 outpatient visits and 65 extra clinical activities were performed monthly. CONCLUSION: We identified that 15% of patients seen have NMO. As patients with NMO have a more severe disease than MS, this data may be important for planning local health care policies.

Objetivo Descrever a casuística de pacientes atendidos no setor de Neuroimunologia da Universidade Federal de São Paulo (UNIFESP) de 1994 a 2013. Método Analisamos o diagnóstico final de todos os pacientes atendidos de 1999 a 2013, sendo o diagnóstico revisado na última consulta e estabelecido de acordo com os critérios específicos para cada doença. O volume de atendimentos clínicos e não clínicos (relatórios e receitas) foram contabilizados para avaliar a carga de trabalho da equipe. Resultados 1.599 pacientes foram avaliados: 816 com esclerose múltipla (EM), 172 com síndromes clínicas isoladas, 178 com neuromielite óptica (NMO), 216 com outras doenças desmielinizantes, 20 com doenças metabólicas, 42 com doenças vasculares e 155 com outros diagnósticos ou diagnósticos indefinidos. Identificamos uma média de 219 consultas e 65 solicitações de relatórios por mês. Conclusão Identificamos que 15% dos pacientes atendidos tem NMO. Por ser uma doença mais incapacitante que a EM estes dados podem ser importantes para o planejamento de políticas de saúde locais. .
