Spectral Doppler ultrasound in selecting an equine embryo receiver.

The aim of this study was to evaluate whether the RI and PI values would help in choosing the best embryo recipient, and observe whether CL vascularization would influence P4 production. During the breeding season 2018/2019, the study was conducted using 35 mares, which is used for reference to collect data for the project on the day of embryo transfer. The utilized mares were divided into five groups followed by the day after ovulation, with D0 being the day of ovulation. Therefore, the five groups are as follows: D4-mares that were on the 4th post-ovulation day; D5-mares that were on the 5th post-ovulation day; and doing so successively for D6, D7 and D8. On the day of embryo transfer, the CL of the mares that selected as recipients was evaluated by B-mode and power flow mode ultrasonography and the right and left dorsal branches of the uterine arteries by spectral Doppler ultrasonography. Blood samples were taken on the day of the embryo transfer for a dosage of P4 concentration by radioimmunoassay. No statistical difference was found between the variables when the mares were separated into pregnant and non-pregnant mares, or when they were separated by age groups. When the groups of mares were compared by the day of embryo transfer, the statistical difference was found between the groups D5 × D6 (p = .0053) and D6 × D8 (p = .0036) in RI variable. In PI variable, the statistical difference was found between the groups D4 × D8 (p = .049), D5 × D6 (p = .0446) and D6 × D8 (p = .0024). We conclude that the mares with RI measurement of uterine arteries near 1.0 are correlated to mares with high CL vascularization and elevated P4 concentration.

CHARCTERIZATION OF FEEDING OF CHILDREN UNDER 24 MONTHS IN UNITS CARED BY THE FAMILY HEALTH STRATEGY.

OBJECTIVE: To describe the median age of introduction and regular food intake by young children in units of the Family Health Strategy. METHODS: Cross-sectional study with 283 young children chosen by uniform stratified cluster sampling. Socio-demographic data on the mother and the child's food intake were collected (age of food introduction and weekly frequency). Foods were grouped into in natura/minimally processed (G1); culinary ingredients (G2); processed (G3) and ultra-processed (G4). The survival analysis was applied to define the median age of food introduction and the chi-square test was used to compare the frequency of food intake, according to the age range (0-5.9; 6-11.9; and 12-23.9 months old). RESULTS: The median duration of exclusive breastfeeding and breastfeeding were three and 19 months, respectively. The age of median food introduction of G1 was six months, except for eggs, milk and coffee (12 months). For oil and salt (G2), the median was 6 months, and for sugar (G2), seven months. The median age of introduction of most food of G4 was 12 months; for infant formulas, it was seven months; cookies and baby food, eight months. Most food had not yet been introduced for children under six months old. For children from six to 11.9 months old, the regular consumption of G4 (≥5 days/week) was higher for cookies (23.8%), bread (21.2%), infant formulas (21.2%) and baby food (35%); and for children from 12 to 23.9 months old, it was higher for cookies (31.2%), bread (57.5%) and baby food (48.7%). CONCLUSIONS: Food introduced and consumed on a regular basis was mainly in natura, at all ages. Processed and ultra-processed food presented a higher frequency of consumption after 12 months old.

RESUMO Objetivo: Descrever a idade mediana de introdução e consumo regular de alimentos por crianças menores de 24 meses em unidades da Estratégia Saúde da Família. Métodos: Estudo transversal realizado com 283 crianças selecionadas por amostragem por conglomerado estratificada uniforme. Foram coletados dados sociodemográficos da mãe e do consumo alimentar da criança (idade de introdução e frequência semanal). Os alimentos foram agrupados em: in natura/minimamente processados (G1); ingredientes culinários (G2); processados (G3) e ultraprocessados (G4). Utilizou-se análise de sobrevida para definição da idade mediana de introdução dos alimentos e teste do qui-quadrado para comparação da frequência de consumo segundo a faixa etária (0 a 5,9; 6 a 11,9; e 12 a 23,9 meses). Resultados: A duração mediana do aleitamento materno exclusivo foi de três meses e do aleitamento materno, de 19 meses. A mediana de introdução dos alimentos do G1 foi de seis meses, exceto para ovo, leite e café (12 meses). Para óleo e sal (G2), a mediana foi de 6 meses e para o açúcar (G2), de sete meses. A mediana da maioria dos alimentos do G4 foi de 12 meses, para fórmulas foi de sete meses, biscoitos e alimentos infantis, oito meses. A maioria dos alimentos ainda não tinha sido introduzida para crianças menores de seis meses. Para crianças de seis a 11,9 meses, o consumo regular (≥5 dias/semana) de G4 foi superior para biscoitos (23,8%), pão (21,2%), fórmulas (21,2%) e alimentos infantis (35,0%); e para crianças de 12 a 23,9 meses foi para biscoitos (31,2%), pão (57,5%) e alimentos infantis (48,7%). Conclusões: Os alimentos introduzidos e consumidos regularmente foram principalmente alimentos in natura, em todas as idades. Alimentos processados e ultraprocessados apresentaram maior frequência de consumo após os 12 meses.

Consumption of minimally processed and ultra-processed foods among students from public and private schools / Consumo de alimentos minimamente processados e ultraprocessados entre escolares das redes pública e privada

ABSTRACT Objective: To compare and analyze the consumption of minimally processed and ultra-processed foods among students from public and private schools. Methods: Study conducted in Uberlândia, MG, with fifth-grade students from three private and six public schools, selected by stratified cluster sampling. We collected data on food consumption using the 24-hour recall. Foods were classified into four groups (G) according to extent and purpose of processing: fresh/minimally processed foods (G1) culinary ingredients (G2), processed foods (G3), and ultra-processed foods (G4). Total energy intake (kcal) of each group, amount of sugar (g), sodium (mg), and fiber (g) were quantified and compared according to administrative affiliation (private or public). Results: Percentage of total energy intake was: G1 - 52%; G2 - 12%; G3 - 5%; e G4 - 31%. Energy intake from G1 (53 vs. 47%), G2 (12 vs. 9%), and G3 (6.0 vs. 0.1%), and amount of sodium (3,293 vs. 2,724 mg) and fiber (23 vs. 18 g) were higher among students from public schools. Energy intake from G4 (36 vs. 28%) and amount of sugar (20 vs. 14%) were higher among students from private schools. The consumption of foods from G1 in the school environment was higher among students from public schools (40 vs. 9%). Conclusions: Foods from G1 represent the highest percentage of total energy intake, while those from G4 constitute a third of calories consumed. Processed juice, sandwich cookie, processed cake, and breakfast cereals are more frequent among private school students; snacks and juice powder are more common for students from public schools.

RESUMO Objetivo: Comparar e analisar o consumo de alimentos minimamente processados e ultraprocessados entre escolares das redes pública e privada. Métodos: Estudo realizado em Uberlândia, MG, com escolares do quinto ano do ensino fundamental em nove escolas (três privadas e seis públicas), selecionados por amostragem estratificada por conglomerado. O consumo alimentar foi analisado utilizando recordatório de 24 horas. Os alimentos foram classificados segundo extensão e propósito do seu processamento em quatro grupos (G): alimentos in natura/minimamente processados (G1), ingredientes culinários (G2), alimentos processados (G3) e ultraprocessados (G4). Os valores energéticos totais (kcal) provenientes de cada grupo, quantidade de açúcar (g), sódio (mg) e fibras (g) foram quantificados e comparados segundo dependência administrativa. Resultados: O consumo de energia foi: G1, 52%; G2, 12%; G3, 5%; e G4, 31%. Os valores energéticos provenientes de G1 (53 vs. 47%), G2 (12 vs. 9%) e G3 (6,0 vs. 0,1%), a quantidade de sódio (3.293 vs. 2.724 mg) e a de fibras (23 vs. 18 g) foram superiores em escolares da rede pública. O valor percentual energético do G4 (36 vs. 28%) e a quantidade de açúcar (20 vs. 14%) foram superiores em escolares da rede privada. O consumo do G1 na escola foi superior nos escolares da rede pública (40 vs. 9%). Conclusões: Alimentos do G1 representam o maior percentual do valor energético total e do G4, um terço das calorias ingeridas. Suco pronto, biscoito recheado, bolo industrializado, cereais matinais são mais frequentes em escolares da rede privada e salgadinhos e suco em pó nos da rede pública.
