The purpose of this cross-sectional study was to investigate the importance of health vigilance in the prevention of cervical cancer. The sample consisted of 536 women. To identify which risk factors were associated with cervical cancer or with an increase in the mortality rate of this kind of cancer, a logistic regression model was used. The Odds Ratios (OR) and their respective 95% confidence intervals were also calculated. Most of them were at the age of highest incidence of cervical cancer (21 - 59 years old), had an unstable conjugal situation, minimal educational level (78.7%), low income (58.3%), consumed alcoholic beverages (56.4%), had a history of smoking (57.0%) and possessed limited knowledge about the prevention. These results are discussed in terms of a predictive model for cervical cancer that considers the importance of public health vigilance in the screening and precocious diagnosis.

Objective: Evaluate pretreatment sarcopenia and anemia as prognostic factors in women undergoing treatment for cervical cancer (CC) with concurrent chemoradiotherapy (CCRT). Methods: 151 women with CC were analysed in this cohort study. Pretreatment computed tomography (CT) images were analysed to assess skeletal muscle index (SMI). Hazard ratios (HR) and multivariate Cox proportional HR were used to analyse association between low SMI, age, body mass index (BMI), haemoglobin levels, histological type, and International Federation of Gynaecology and Obstetrics (FIGO) stage with PFS and OS. Results: A total of 151 patients were included, 53 (35.1%) presented pretreatment sarcopenia;51 (34%) stage I/II and 100 (66%) stage III/IV. Among those patients in advanced stage (III/IV) 37 (70%) (p = 0.28) were sarcopenic at the beginning of treatment. Sarcopenia was associated with worse progression-free survival (PFS) and overall survival (OS) in our cohort [HR 0.97 (p = 0.01)] [HR 0.73 (p = 0.001)], as well as anemia [HR 0.73 (p = 0.001)] [HR 0.78 (p = 0.001)]. Linear regression models indicated that despite showing no association with age, neutrophil or platelet counts, sarcopenia was associated with pretreatment anemia levels (p = 0.01). After a multivariate analysis, only haemoglobin (anemia) and complete CCRT remained associated with PFS and OS. Sarcopenia and anemia were associated with worse PFS and OS in FIGO stage I/II. Conclusion: Pretreatment sarcopenia was significantly associated with low haemoglobin levels. Anemia and incomplete CCRT were independently associated with poor prognosis in women with CC. Pretreatment sarcopenia, as low SMI, was a predictor of poor prognostic in early stages of CC.

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.

Zika virus (ZIKV), a mosquito-borne flavivirus, has been associated with benign infections for decades. However, it has become a public health concern due to its association with severe fetal and neurological complications. Although many efforts have been made to control ZIKV infection, approved vaccines or antiviral drugs are still lacking. Consequently, the development of new effective anti-ZIKV agents is urgently needed. In this context, we investigated the antiviral potential of pyrazolone derivatives against ZIKV replication using in silico and in vitro methods. The four pyrazolone derivatives evaluated (1a, 1b, 1c, and 1d) inhibited over 50% of ZIKV replication with low cytotoxicity. Among them, compound 1b exhibited the most potent activity (EC50 = 4.3 μM) and the highest selectivity (SI = 342). Mechanism of action studies indicated that these compounds act at early stages of virus replication, and compound 1b can also directly inactivate ZIKV particles. Molecular docking studies suggested that these compounds can bind to and block the activity of ZIKV NS5 methyltransferase. Finally, pharmacokinetic and toxicological predictions have reinforced the safety and drug-like profiles of these derivatives. In conclusion, the pyrazolone scaffold proved to be valuable for anti-ZIKV drug development, and the derivatives studied deserve further investigation.
