Introduction: Prenatal care is crucial for maternal and fetal health, highlighting the importance of obstetric risk stratification. This enables personalized care, avoiding unnecessary interventions and reducing costs. Conditions such as first trimester bleeding, spontaneous abortion, gestational trophoblastic disease, and ectopic pregnancy require specific approaches. Early identification of these complications is vital, especially in urgent and emergency obstetric cases, which demand immediate hospital attention. Objective: Comprehensive review of first trimester pathologies and gestational hypertension, focusing on obstetric risks and personalized prenatal management. Methods: Literature review on bleeding and gestational hypertension. Results: The study provides a detailed analysis of pathologies associated with first trimester uterine bleeding and hypertensive disorders, focusing on obstetric risk stratification. The main causes of maternal and fetal mortality are hypertensive disorders, hemorrhages, infections, childbirth complications, and abortion. Spontaneous abortion is common, with different classifications, ranging from threatened to missed abortion. Infected abortion is a severe complication. Brazil has restrictive abortion laws, but many unsafe abortions occur, resulting in high public health costs. Pharmacological treatment with misoprostol is a safe option. Other pathologies include gestational trophoblastic disease, ectopic pregnancy, and placenta previa. Preeclampsia and eclampsia are severe conditions requiring immediate treatment to avoid complications. Conclusion: Early identification and management of obstetric risk factors, such as uterine bleeding, are essential for positive maternal and fetal outcomes. A multidisciplinary approach is fundamental.

Standardization of Sampling for Isolation of Exosome-Like Small-Extracellular Vesicles from Peripheral Blood from Reproductive-Aged Women

引用

Open journal of Obstetrics and Gynecology 2018年第11期8卷 1063-1070页

作者： jéssica Maria Diehl j.lia Abbade Tronco Natália Prearo Moco Graziela Gorete Romagnoli Ana Clara Faquineli Cavalcante Mendes de Avila j.liano coelho da Silveira Márcia Guimaraes da Silva Bruna Ribeiro de Andrade Ramos Department of Pathology Botucatu Medical School Sao Paulo State University (UNESP) Botucatu Brasil Três Lagoas Integrated College—FITL/AEMS Três Lagoas Brasil Department of Microbiology and Immunology Biosciences Institute Sao Paulo State University (UNESP) Botucatu Brasil Department of Veterinary Medicine Faculty of Zoology and Food Engineering Sao Paulo University Pirassununga Brasil

Exosome-like small-extracellular vesicles (sEVs) are extracellular vesicles that act in intercellular communication and are involved in several biologic and pathologic processes. While sEVs increase the stability of their cargo molecules, there is still a need for standardization of sampling and isolation of these microvesicles. We aimed to determine the best sampling method for isolation of sEVs from peripheral blood from reproductive-aged women. Material and Methods: We included samples of plasma from our biobank collected in 2014 by venipuncture in heparin tubes and stored at -80°C. We also included blood samples collected in heparin tubes and Ethylenediamine tetraacetic acid (EDTA) tubes and stored at -80°C for one to two weeks prior processing. All blood samples were collected from the same nine reproductive-aged female volunteers. sEVs were isolated from plasma by ultracentrifugation and filtration and indirectly quantified using Pierce BCA Protein Assay kit. Transmission electron microscopy (TEM) and Nano Tracking Analysis (NTA) were performed to confirm the isolation of sEVs. Results and Discussion: TEM and NTA confirmed the isolation of sEVs. Protein concentration of short-time stored heparin samples was not statistically different from long-time stored heparin samples (1847.2 ± 651.4 vs. 2363.2 ± 1025.1, p = 0.14). There was no difference between heparin and EDTA plasma samples recently collected (2363.2 ± 1025.1 vs. 2044.8 ± 653.2, p = 0.44). In conclusion, blood samples may be collected using heparin or EDTA for isolation of sEVs. Long-time stored plasma samples maintain sEVs integrity and may be used, especially in comparative studies.

The Quarter-Horses regularly participate in non-traditional sports that simulate activities on cattle ranches. In the vaquejada races, the horses run at about 30 km/h, reaching maximum heart rates of around 200 bpm, indicating the great physical effort during competitions and with that could impact welfare. To test the hypothesis that vaquejada horses can be evaluated for the quality of welfare through a combination of non-invasive and invasive methods, an experiment was developed that aimed to assess the quality of welfare through thermography and blood biomarkers before and after vaquejada races. Ten vaquejada horses, which were in regular competition, were submitted to the vaquejadas racing test were used. Thermography was performed in 14 regions of interest (head, neck and thorax) in the following phases: pre-race and +1, +4 and +24 hours of the races. Blood samples were collected in pre-race, immediately after and +1, +4 and +24 hours of the races. Results were submitted to ANOVA and Tukey’s test, with p set at 5%. Thermography showed that local temperatures before the race and +24 hours after the races were similar (p > 0.05), as well as between +1 and +4 hours after the races (p > 0.05), which showed higher surface temperatures than the first group (pre-race and +24 hours) (p 0.05) after the exercises. In conclusion, the vaquejada horses evaluated by infrared thermography and blood analyses maintained the quality of well-being, with the physiological elevation of several parameters after the races and recovery in less than 24 hours after the races. Thermographic images were also able to help in the analysis of the regions of interest that have contact with harnesses, demonstrating that the use of adequate and correct equipment does not compromise animal welfare.

In recent decades, the intensity of training and equestrian competitions has significantly increased, thus the assessment of the well-being of the equine athlete has become essential in all equestrian modalities. The aim of this study was to ascertain whether equine athletes submitted to a vaquejada simulation test (VqST), comprised of three races, presented changes in blood biomarkers related to stress and health status. Fourteen healthy Quarter Horses, used as pull horses in this equestrian modality, were evaluated. Ten animals were submitted to the VqST and the remaining four were used as a control group. Blood samples were collected pre-test (during fast), immediately after, and at 1, 4 and 24 hours of recovery. The assessed blood biomarkers included cortisol, interleukin (IL)-6, IL-1β, iron, urea, creatinine, and gamma-glutamyl transferase (GGT) concentrations and results were analyzed using One Way ANOVA (time) with the SigmaStat 13.0 software. No differences between sample times were detected in both groups (p > 0.05) and no differences were found between groups (p > 0.05). The results suggest that all horses were well conditioned for the level of effort imposed by the three vaquejada races. The adaptation to physical exercise may enable the regulation of the acute response to stress in the tissues involved in the exercises, with no differences being observed in stress and health biomarkers, such as IL-6, IL-1β and cortisol. In conclusion, well-conditioned vaquejada horses exhibit a balanced regulation of biological processes, which contributes an increased athletic longevity and better quality of athletic life.

Mangaba (Hancornia speciose Gomes—Apocynaceae) is an important fruit tree in Brazil and has an unexplored stock germplasm collection. Commercial varieties are unavailable and little is known about its potential as a source of genetic diversity for molecular breeding programs. Progeny tests may improve studies on commercial variability and facilitate genetic improvement of the species. Our aim was to evaluate the genetic diversity and structure of accessions and progeny from the Mangaba Genebank of Embrapa Coastal Tablelands. We estimated the genetic diversity of 96 individuals using 4 SSR markers. The mean observed heterozygosity was lower than expected, showing an excess of homozygotes, corroborated by the positive coefficient of endogamy. The genetic diversity indexes (Fst) and Nei’s unbiased genetic identity (GI) revealed, in general, moderate genetic diversity between accessions. The relationship between matrices and progenies showed that there may be a greater degree of genetic information sharing between the ABP1 and ABP2 accessions. The Bayesian analysis suggested the presence of two distinct groups of genotypes (K = 2). These results will assist future breeding programs and facilitate the conservation of mangaba.

Long COVID has been studied as different sequelae that some individuals can develop after the acute phase of the disease. Persistent symptoms such as dry cough, fatigue, and dyspnea can remain after six months of COVID-19 cure. Others such as lung fibrosis, kidney injury, and thrombotic risk also are observed. Here, a deep review of each human organ and system infected by the virus was performed aiming to show how molecules expression and cell signaling can induce the organism cure or injuries and, subsequently sequelae. The review also suggests the importance of public health surveillance for these cases including a more comprehensive analysis of molecular biology tools that can clarify and assist in the prognosis, treatment, and preventive methods for potentially more serious disorders in post-COVID-19 patients.
