Características de gestantes com sífilis em um hospital universitário do Paraná

A sífilis em gestante constitui uma importante causa evitável de morbimortalidade neonatal. O objetivo do estudo foi estimar a magnitude e características de gestantes com sífilis atendidas em um hospital universitário da região oeste do Paraná. Foi realizado um estudo descritivo, conduzido com revisão de prontuários e fichas de notificação de gestantes diagnosticadas com sífilis, no período de 2010 - 2016. Os resultados referem-se a 121 casos, a taxa de detecção de sífilis em gestantes foi 5,96 casos por mil nascidos vivos. Mostrou-se mais frequente em mulheres com idade ≥ 20 anos e escolaridade ≤ 8 anos. O tratamento foi inadequado em 68,7% das gestantes e 14,9% dos recém-nascidos foram notificados com sífilis congênita. Recomenda-se melhorar a qualidade do pré-natal, dos registros de notificação e providenciar educação continuada para os profissionais de saúde

Data_Sheet_1_Methylene blue in sepsis and septic shock: a systematic review and meta-analysis.PDF

BackgroundMethylene blue is an interesting approach in reducing fluid overload and vasoactive drug administration in vasodilatory shock. The inhibition of guanylate cyclase induced by methylene blue infusion reduces nitric oxide production and improves vasoconstriction. This systematic review and meta-analysis aimed to assess the effects of methylene blue administration compared to placebo on the hemodynamic status and clinical outcomes in patients with sepsis and septic shock.MethodsThe authors specifically included randomized controlled trials that compared the use of methylene blue with placebo in adult patients with sepsis and septic shock. The outcomes were length of intensive care unit stay, hemodynamic parameters [vasopressor use], and days on mechanical ventilation. We also evaluated the abnormal levels of methemoglobinemia. This systematic review and meta-analysis were recorded in PROSPERO with the ID CRD42023423470.ResultsDuring the initial search, a total of 1,014 records were identified, out of which 393 were duplicates. Fourteen citations were selected for detailed reading, and three were selected for inclusion. The studies enrolled 141 patients, with 70 of them in the methylene blue group and 71 of them in the control group. Methylene blue treatment was associated with a lower length of intensive care unit stay (MD −1.58; 95%CI −2.97, −0.20; I2 = 25%; p = 0.03), decreased days on mechanical ventilation (MD −0.72; 95%CI −1.26, −0.17; I2 = 0%; p = 0.010), and a shorter time to vasopressor discontinuation (MD −31.49; 95%CI −46.02, −16.96; I2 = 0%; p ConclusionAdministering methylene blue to patients with sepsis and septic shock leads to reduced time to vasopressor discontinuation, length of intensive care unit stay, and days on mechanical ventilation.Systematic review registrationhttps://www.crd.york.ac.uk/prospero/display_record.php?ID=CRD42023423470, CRD42023423470.</p

Profile of caregivers of Parkinson’s disease patients and burden measured by Zarit Scale Analysis of potential burden-generating factors and their correlation with disease severity

Abstract Parkinson’s disease (PD) promotes burden among patients and caregivers. Objective: To analyze whether disease severity (UPDRS and Karnofsky index), total disease duration, patient cognitive status (MMSE), presence of other diseases, patient age, socioeconomic conditions (ABEP2015), living together with patient, total time caregiving, weekly hours of care and presence of assistance from other caregivers are correlated with, and influence statistically, the degree of caregiver burden measured by the Zarit Burden Interview (ZBI). Methods: After ethics Committee approval, patients and respective caregivers were recruited. Following evaluation with the proper scales, all data were submitted to Pearson’s correlation method and multivariate linear regression analysis (ANOVA). Results: A total of 21 patients and respective caregivers were evaluated. 72% (N=15) of caregivers reported burden. One third of caregivers reported a moderate or severe level of burden. A cause-effect relationship could not be established by the statistical method adopted, but disease severity measured by the UPDRS was the sole variable showing statistically significant moderate positive Pearson’s correlation with ZBI (r=0.48, for p<0.05). On ANOVA, however, no independent variable had a statistically significant impact on ZBI scores. Conclusion: Despite our conflicting results, optimization of the available treatment, with better control of PD severity, can be considered an important element to effectively achieve the goal of reducing burden among caregivers

Role of Nutrients and Foods in Attenuation of Cardiac Remodeling through Oxidative Stress Pathways

Cardiac remodeling is defined as a group of molecular, cellular, and interstitial changes that manifest clinically as changes in the heart’s size, mass, geometry, and function after different injuries. Importantly, remodeling is associated with increased risk of ventricular dysfunction and heart failure. Therefore, strategies to attenuate this process are critical. Reactive oxygen species and oxidative stress play critical roles in remodeling. Importantly, antioxidative dietary compounds potentially have protective properties against remodeling. Therefore, this review evaluates the role of nutrients and food as modulators of cardiac remodeling

Oxidative Stress as a Therapeutic Target of Cardiac Remodeling

Cardiac remodeling is defined as a group of molecular, cellular, and interstitial changes that clinically manifest as changes in the heart’s size, mass, geometry, and function after different stimuli. It is important to emphasize that remodeling plays a pathophysiological role in the onset and progression of ventricular dysfunction and subsequent heart failure. Therefore, strategies to mitigate this process are critical. Different factors, including neurohormonal activation, can regulate the remodeling process and increase cell death, alterations in contractile and regulatory proteins, alterations in energy metabolism, changes in genomics, inflammation, changes in calcium transit, metalloproteases activation, fibrosis, alterations in matricellular proteins, and changes in left ventricular geometry, among other mechanisms. More recently, the role of reactive oxygen species and oxidative stress as modulators of remodeling has been gaining attention. Therefore, this review assesses the role of oxidative stress as a therapeutic target of cardiac remodeling

Post-Cardiac Arrest: Mechanisms, Management, and Future Perspectives

Cardiac arrest is an important public health issue, with a survival rate of approximately 15 to 22%. A great proportion of these deaths occur after resuscitation due to post-cardiac arrest syndrome, which is characterized by the ischemia-reperfusion injury that affects the role body. Understanding physiopathology is mandatory to discover new treatment strategies and obtain better results. Besides improvements in cardiopulmonary resuscitation maneuvers, the great increase in survival rates observed in recent decades is due to new approaches to post-cardiac arrest care. In this review, we will discuss physiopathology, etiologies, and post-resuscitation care, emphasizing targeted temperature management, early coronary angiography, and rehabilitation
