Impacts of Consumption of Ultra-Processed Foods on the Maternal-Child Health: A Systematic Review.

Background and Aims: Changes in eating patterns have been leading to an increase in the consumption of ultra-processed foods (UPF), negatively impacting the quality of the diet and generating risk of harm to the health of the adult population, however, there is no systematized evidence of the impact of UPF in maternal-child health. Thus, in this study we aimed to evaluated the association between UPF consumption and health outcomes in the maternal-child population. Methods: Systematic review registered on the International Prospective Register of Systematic Reviews (PROSPERO) (CRD42021236633), conducted according to the PRISMA diagram in the following databases: PubMed, Medline, Scopus, Web of Science, Scielo, and CAPES thesis and dissertation directory. We included original cross-sectional, case-control and cohort studies in any language. Eligibility criteria were (a) food consumption assessment by the NOVA classification, (b) health outcome (nutritional or diseases), and (c) maternal-child population (pregnant, lactating women and infants/children). All data were analyzed and extracted to a spreadsheet structured by two independent reviewers. We evaluated the methodological quality of the studies included using the Newcastle-Otawa Scale and RoB 2. Results: Searches retrieved 7,801 studies and 15 contemplated the eligibility criteria. Most studies included were cohort studies (n = 8, 53%), had children as their population (n = 9, 60%) and only one study evaluated UPF consumption in infants and lactating women. Panoramically, we observed that a higher participation of UPF in children's diet has been associated with different maternal-child outcomes, such as increase of weight gain, adiposity measures, overweight, early weaning, lower diet quality, metabolic alterations, diseases, and consumption of plastic originated from packaging. Only one of the studies included did not present high methodological quality. Conclusion: Despite the limited literature on UPF consumption and health outcomes in the maternal-child population, the highest UPF consumption negatively impacted nutrition and disease development indicators in pregnant, lactating women and children. Considering the expressive participation of these foods in the diet, other studies should be conducted to further investigate the impact of UPF consumption on different health indicators, especially in the lactation phase for this was the one to present the most important knowledge gap.

First complete genome sequence and molecular characterization of Canine morbillivirus isolated in Central Brazil.

The Brazilian regions are still highly endemic areas for Canine morbillivirus [canine distemper virus (CDV)]. However, little is known regarding the genetic variability of the strain circulating in several Brazilian regions. Here, we report the first full-length genome and molecular characterization of CDV isolated from domestic dogs in the Brazilian Center-West region. Sequence alignment and phylogenetic analyses based on deduced amino acid and nucleotide sequences showed that the isolated strain is characterized as the South America-I/Europe genotype. However, it segregates into a CDV subgenotype branch. Interestingly, both H and F proteins have a gain of a potential N-glycosylation sites compared to the Onderstepoort vaccine strain. Therefore, this study provides a reference to further understand the epidemic and molecular characteristics of the CDV in Brazil.

Psoroptes ovis mange in a dog in Brazil.

Psoroptes ovis (Acari: Psoroptidae, Hering, 1838) is an ectoparasite that poses a high risk to herd animals and causes a severe dermal disease called psoroptic mange. This work aimed to report P. ovis parasitism in a dog. A male Pinscher that lives in rural areas and had free access to sheep farming showed hair loss in the dorsal region and mild itching. Dermatological examination demonstrated irregular alopecia, scabs, dry desquamation and erythema around the dorsal region of the thorax and pelvis. Hemogram has shown mild eosinophilia and the fungal culture was negative. In skin scrapings, P. ovis was observed, and its morphological characteristics were recorded. Treatment with ivermectin (0.5 mg/kg) was initiated orally once weekly for six weeks and amitraz for environmental control shown positive results. The diagnosis of psoroptic mange in dogs was performed based on morphological characterization of mite and the report of sheep contact. This is the first report of the occurrence of P. ovis in dog.
