C-reactive protein to albumin ratio may predict in-hospital mortality in non-ST elevation myocardial infarction.

Objective: The authors investigated the value of novel inflammatory markers, systemic immune-inflammation index and C-reactive protein to albumin ratio (CAR), to predict in-hospital mortality in patients with non-ST elevation myocardial infarction (NSTEMI). Materials & methods: A total of 308 patients who underwent percutaneous coronary intervention because of NSTEMI were retrospectively included in the study. Killip classification, Thrombolysis in Myocardial Infarction score, SYNTAX score, and CAR and systemic immune-inflammation index values were calculated. Results: CAR (cutoff: 0.0864; sensitivity: 94.1%; specificity: 40.5%; p = 0.008) and Killip classification (cutoff: 2.5; sensitivity: 64.7%; specificity: 8.9%; p = 0.001) were found to be significantly higher in determining in-hospital mortality. Conclusion: This study revealed that CAR is an inexpensive and significant factor in predicting in-hospital mortality in patients undergoing percutaneous coronary intervention for NSTEMI.

The Relation between Plasma Nesfatin-1 Levels and Aggressive Behavior in Pit Bull Dogs.

Aggression is a prevalent and concerning behavioral issue in dogs. Pit Bull dogs, known for their high levels of aggression, are recognized as a focus of concern in society. In our study, we aimed to investigate the behavioral characteristics of Pit Bull dogs and explore the potential roles of peptides involved in the neurobiology of aggression. Initially, female, and male dogs underwent aggression tests, and their aggression levels were categorized. Plasma nesfatin-1, serotonin, oxytocin, and dopamine levels were quantified using ELISA, with blood samples collected after a 24 h fasting period and 2 h post-refeeding. Our findings indicate that aggression in Pit Bull dogs correlates with decreased plasma nesfatin-1, serotonin, and oxytocin levels, while dopamine levels increase. The study's findings indicate that fasted dogs exhibited lower plasma levels of nesfatin-1, serotonin, and dopamine, while plasma oxytocin levels were higher. Furthermore, while the research findings do not suggest a significant relationship between the severity of aggression and the gender of the dog, male Pit Bull breeds appear to have higher plasma nesfatin-1 and serotonin levels compared to their female counterparts. The study's findings demonstrate that nesfatin-1, serotonin, oxytocin, and dopamine play pivotal roles in Pit Bull dogs' aggression, indicating potential interactions among these neuropeptides at the central nervous system level.

Does thromboprophylaxis prevent venous thromboembolism after major orthopedic surgery? / A tromboprofilaxia evita o tromboembolismo venoso após cirurgia ortopédica de grande porte?

OBJECTIVE: Pulmonary embolism (PE) is an important complication of major orthopedic surgery. The aim of this study was to evaluate the incidence of venous thromboembolism (VTE) and factors influencing the development of VTE in patients undergoing major orthopedic surgery in a university hospital. METHODS: Patients who underwent major orthopedic surgery (hip arthroplasty, knee arthroplasty, or femur fracture repair) between February of 2006 and June of 2012 were retrospectively included in the study. The incidences of PE and deep vein thrombosis (DVT) were evaluated, as were the factors influencing their development, such as type of operation, age, and comorbidities. RESULTS: We reviewed the medical records of 1,306 patients. The proportions of knee arthroplasty, hip arthroplasty, and femur fracture repair were 63.4%, 29.9%, and 6.7%, respectively. The cumulative incidence of PE and DVT in patients undergoing major orthopedic surgery was 1.99% and 2.22%, respectively. Most of the patients presented with PE and DVT (61.5% and 72.4%, respectively) within the first 72 h after surgery. Patients undergoing femur fracture repair, those aged ≥ 65 years, and bedridden patients were at a higher risk for developing VTE. CONCLUSIONS: Our results show that VTE was a significant complication of major orthopedic surgery, despite the use of thromboprophylaxis. Clinicians should be aware of VTE, especially during the perioperative period and in bedridden, elderly patients (≥ 65 years of age). .

OBJETIVO: A embolia pulmonar (EP) é uma complicação importante de cirurgia ortopédica de grande porte. Este estudo visou avaliar a incidência de tromboembolismo venoso (TEV) e os fatores que influenciam o desenvolvimento de TEV em pacientes submetidos a cirurgia ortopédica de grande porte em um hospital universitário. MÉTODOS: Pacientes submetidos a cirurgia ortopédica de grande porte (artroplastia de quadril, artroplastia do joelho ou reparação de fratura de fêmur) entre fevereiro de 2006 e junho de 2012 foram incluídos retrospectivamente no estudo. As incidências de EP e de trombose venosa profunda (TVP) foram avaliadas, assim como os fatores que influenciaram sua ocorrência, tais como o tipo de cirurgia, idade e comorbidades. RESULTADOS: Foram revisados os prontuários médicos de 1.306 pacientes. As proporções de artroplastia do joelho, artroplastia de quadril e reparação de fratura de fêmur foram, respectivamente, de 63,4%, 29,9% e 6,7%. A incidência cumulativa de EP e TVP nos pacientes submetidos a cirurgia ortopédica de grande porte foi, respectivamente, de 1,99% e 2,22%. A maioria dos pacientes apresentou EP e TVP (61,5% e 72,4 %, respectivamente) nas primeiras 72 h após a cirurgia. Pacientes submetidos à reparação de fratura de fêmur, aqueles com idade ≥ 65 anos, e pacientes acamados tinham um risco maior de desenvolver TVP. CONCLUSÕES: Nossos resultados demonstram que o TEV foi uma complicação importante de cirurgia ortopédica de grande porte, apesar da utilização de tromboprofilaxia. Os médicos clínicos devem estar alerta para a ocorrência ...

The relationship between hs-CRP and asthma control test in asthmatic patients

Background: High sensitive C-reactive protein (hs-CRP) has been shown to be associated with asthma in recent studies. However, the relationship between hs-CRP and the control of asthma has not been clearly identified yet. Objective: To investigate the association of hs-CRP with asthma control test (ACT), which reveals the degree of asthma control, and to compare hs-CRP in adults with mild and moderate asthma in chronic, stable asthmatic patients. Methods: Thirty patients with physician-diagnosed asthma (11 mild, 19 moderate), and 30 healthy patients were enrolled in the study. In addition to medical history and physical examination, asthma was assessed according to GINA guideline. Respiratory function tests (RFT) and ACT were performed. The serum hs-CRP levels of all cases patients were measured. Results: The levels of hs-CRP in asthmatic patients were significantly higher than those in the control cases (p=0.002). The serum hs-CRP levels in the moderate asthmatics were significantly higher than those in the mild asthmatic ones (p=0.04). When asthmatic cases were divided into two groups according to ACTs; the levels of hs-CRP in the groups of ACT minor=20 (uncontrolled groups) were significantly higher than the groups of ACT major=20 (controlled groups) (p=0.02). The hs-CRP levels showed significant correlations with ACT (p=0.00, r=−0.91) and asthma severity (p=0.04, r=038) in asthmatic patients. Conclusion: In conclusion it was shown that hs-CRP is related with asthma severity and ACT, and hs-CRP is a potential sensitive marker which reveals the severity and the control of asthma(AU)
