The regulation of biological products has evolved rapidly in recent years due to quality issues impacting people's lives and the advent of new technologies, with constant changes in regulations that dictate how a product is registered, produced, and monitored. In the case of vaccines, the responsibility of regulators and manufacturers in guaranteeing quality, safety, and efficacy is even more critical, since vaccines are mostly used in children and healthy patients. In this scenario, manufacturers need to create strategies to keep their products and installations adequate and up-to-date with a fully operational quality system. Meanwhile, regulatory agencies have the role of guaranteeing that products meet the established criteria without compromising the supply of medicines to the population.Immunization is one of the most effective measures to protect individuals and the population against vaccine-preventable diseases. Vaccines are safe and effective products, but like any other drug they can cause adverse events, which tend to become more visible as the diseases are controlled, eliminated, or eradicated. This study analyzed activities in the surveillance of adverse events following immunization (AEFI) based on data from the scientific literature, websites of immunization programs and health andregulatory agencies, and the authors' expertise in the areas of immunizations and pharmacovigilance. With the increase in the number of vaccines in the basic immunization schedule and expansion of the population's access, it has become essential to establish an efficient surveillance system for AEFI in Brazil. However, underreporting of cases in Brazil and in other countries hinders the detection of AEFI, especially rare events. Constantly updated information on vaccines' risks and benefits allows immunization programs to provide rapid and clear responses to rumors of AEFI. This ensures the system's reliability, especially in the face of the growing antivaccine movement and the increasing influence of social media in public opinion.Moyamoya disease (MMD) is currently thought to involve endothelial progenitor cells (EPCs). We investigated whether superparamagnetic iron oxide (SPIO) can be used to label EPCs. Mononuclear cells from 10 moyamoya disease patients were isolated, and cluster of differentiation 133 (CD133) positive cells sorted by magnetic-activated cell sorting were cultured in vitro. The positive rates of CD133, vascular endothelial growth factor receptor (VEGFR)-2, and cluster of differentiation 34 (CD34) were detected by flow cytometry. The cells were co-cultured with fluorescence labeled Dil-acetylated-low-density lipoprotein (Dil-ac-LDL) and Ulex europaeus agglutinin-1 (UEA-1) to observe the endocytosis of Dil-ac-LDL and binding to UEA-1. Prussian blue staining and transmission electron microscopy were used to observe the endocytosis of different SPIO concentrations in EPCs, and CCK-8 was used to detect proliferation of cells transfected with different concentrations of SPIO. T2 weighted imaging (T2WI) signals from magnetic resonance imaging after SPIO endocytosis were compared. CCG-203971 mouse Positive rates of CD133, VEGFR-2, and CD34 on sorted mononuclear cells were 68.2±3.8, 57.5±4.2, and 36.8±6.5%, respectively. The double-positive expression rate of CD34 and VEGFR-2 was 19.6±4.7%, and 83.1±10.4% of cells, which showed the uptake of Dil-ac-LDL and binding with UEA-1. The labeling efficiencies of SPIO at concentrations of 25 and 50 μg/mL were higher than for 12.5 μg/mL. The proliferation of cells was not influenced by SPIO concentrations of 12.5 and 25 μg/mL. After labeling, the T2WI of EPCs was reduced. The concentration of 25 μg/mL SPIO had high labeling efficiency detected by magnetic resonance imaging (MRI) without decreased EPCs viability.Norovirus (NoV) is the main cause of gastroenteritis outbreaks worldwide. Although NoV spreads mainly from person to person, it is estimated that a large proportion of NoV outbreaks are caused by foodborne transmission. Bivalve mollusks are one of the most important foods involved in NoV transmission to humans. Little is known about NoV prevalence in shellfish harvested and commercialized in Brazil. The aim of this study was to map, for the first time, the distribution of NoV contamination in oysters and mussels harvested and commercialized in the coast of Pernambuco state, northeast Brazil. A total of 380 mollusks (260 oysters and 120 mussels) were collected between February and August 2017 either directly from harvesting areas or obtained from beach vendors at 17 sites in Pernambuco. Samples were processed and tested for NoV contamination using a SYBR Green real-time PCR assay. link2 All samples were negative for NoV GI or GII contamination, suggesting a low risk of NoV contamination from this food source during the study period. Additional surveys in different areas of the Brazilian coast are warranted to monitor the risk of NoV infection upon seafood consumption.Sensory neuropathy is a dose-limiting side effect of oxaliplatin-based cancer treatment. This study investigated the antinociceptive effect of amifostine and its potential neuroprotective mechanisms on the oxaliplatin-related peripheral sensory neuropathy in mice. Oxaliplatin (1 mg/kg) was injected intravenously in Swiss albino male mice twice a week (total of nine injections), while amifostine (1, 5, 25, 50, and 100 mg/kg) was administered subcutaneously 30 min before oxaliplatin. Mechanical and thermal nociceptive tests were performed once a week for 49 days. Additionally, c-Fos, nitrotyrosine, and activating transcription factor 3 (ATF3) immunoexpressions were assessed in the dorsal root ganglia. In all doses, amifostine prevented the development of mechanical hyperalgesia and thermal allodynia induced by oxaliplatin (P less then 0.05). Amifostine at the dose of 25 mg/kg provided the best protection (P less then 0.05). Moreover, amifostine protected against neuronal hyperactivation, nitrosative stress, and neuronal damage in the dorsal root ganglia, detected by the reduced expression of c-Fos, nitrotyrosine, and ATF3 (P less then 0.05 vs the oxaliplatin-treated group). In conclusion, amifostine reduced the nociception induced by oxaliplatin in mice, suggesting the possible use of amifostine for the management of oxaliplatin-induced peripheral sensory neuropathy.The epidermis, the outermost layer of the skin, is the first barrier that comes into contact with the external environment. It plays an important role in resisting the invasion of harmful substances and microbial infections. The skin changes with age and external environmental factors. This study aimed to investigate epidermal stem cells during the process of aging. This study enrolled 9 volunteers with benign pigmented nevus for clinical dermatologic surgery. The phenotypes associated with skin aging changes such as skin wrinkles and elasticity of the unexposed/healthy parts near benign pigmented skin were measured, and epidermal stem cells from this region were isolated for transcriptome sequencing. The results showed that epidermal stem cells could be obtained by magnetic activated cell sorting (MACS) with high purity. Results of the transcriptome sequencing revealed that aquaporin (AQP)5 significantly decreased in the epidermal stem cells with age, and further functional experiments revealed that AQP5 could promote the proliferation and dedifferentiation of HaCaT, but did not influence cell apoptosis. In summary, AQP5 regulated the proliferation and differentiation of epidermal stem cells in skin aging, and it may play an important role in the balance of proliferation and differentiation. However, further studies are needed to determine the mechanism by which AQP5 regulates the proliferation and differentiation of epidermal skin cells in aging.
to describe the structure used in the School Health Program and analyze the association between its material resources and the actions carried out.
cross-sectional, quantitative, analytical, and normative study. A normative instrument of the program was applied to collect data from May to July 2017 with 105 Family Health Strategy professionals. Data were organized and analyzed using descriptive and inferential statistics on IBM SPSS Statistics 22.0 software.
financial resources were made available with low periodicity; the most used human resources were dentists; the most frequent infrastructure resource was the school; the most frequently used materials were those related to administrative support (legal-size paper and pen) and clinical resources (fluoride, toothbrush, and toothpaste). link3 An association was identified between resources and anthropometric assessment activities and vaccination status.
the program structure showed reduced financial resources and priority participation of human resources from the health sector, and the actions were carried out by using the school infrastructure and administrative and clinical materials.

to determine the degree of association between clinical judgment and diagnostic reasoning of nursing students in clinical simulation.
this is a correlational research design using a quantitative approach. The sample consisted of 41 nursing students who assisted a patient with vaso-occlusive crisis in a high-fidelity clinical simulation setting. The instruments used included the Lasater Clinical Judgment Rubric - Brazilian Version and the Diagnostic Thinking Inventory.
clinical judgment was associated with diagnostic reasoning (r=0.313; p=0.046), as well as the "noticing" aspect of clinical judgment with diagnostic reasoning (r=0.312; p=0.047).
the results show that skills to interpret patient data are associated with diagnostic reasoning skills. Teaching clinical judgment skills is necessary to develop the diagnostic reasoning of nursing students.

to evaluate the effectiveness of educational intervention in the knowledge and attitude of candidates for gastroplasty.
randomized controlled clinical trial with 56 preoperative patients (intervention=28; control=28). The control group received routine care from the health institution and the intervention group participated in a book-mediated educational intervention. Forms were used for clinical-epidemiological characterization and evaluation of knowledge/attitude about bariatric surgery, which were reapplied seven weeks after intervention. RBR-297fzx.
in the pre-test there was no significant difference between the groups (p=0.254). In the post-test, the group that received verbal guidance had a mean score of 19.5 (± 6.17) and the group reading the booklet averaged 31.1 (± 2.96), p=0.000. The attitude is adequate, especially for care such as vitamin supplement intake, water intake and physical activity practice.
the educational intervention mediated by booklet was effective in improving knowledge and attitude when compared to verbal guidance.
