Difficulties Faced by Physicians in the Diagnosis of Endometriosis in the Brazilian Public Health System

Health 2023年第7期15卷 788-795页

Endometriosis is a clinical and recurrent condition characterized by the presence of functional endometrial tissue outside the uterine cavity and myometrium. It is estimated that 6% to 10% of women of reproductive age, 50% to 60% of adolescents and adults with pelvic pain, and up to 50% of women with infertility are pregnant from the condition. However, this proportion tends to be even greater due to the difficulty in diagnosing it: because it presents different symptoms, lack of information from health professionals, and a high-cost diagnostic test. Another aggravating factor is the average time from the onset of symptoms to the medical diagnosis, which even today ranges from five to ten years;this delay has consequences for disease progression, as it prevents early treatment, which is important for improving pain levels and physical and psychological well-being. Aware of these mishaps, it is therefore important to assess the difficulties faced by doctors in the diagnosis of endometriosis in the public health system, in Brazil, the Unified Health System (SUS). With this purpose, a cross sectional was carried out, developed in the virtual environment using traffic in Google forms, with the difficulties quantified in the Likert scale. Participating physicians pointed out a medium difficulty for patients with endometriosis to access the consultation (58%) and moderate difficulty (52%) to perform an ultrasound examination;also signaled great difficulty in performing magnetic resonance imaging (77%) and laparotomy (61%) in these patients. It is hoped that knowledge about the difficulties faced by physicians in the diagnosis of endometriosis in the SUS will give these physicians a voice and corroborate, even if minimally, so that there is more research that provokes the search for these difficulties, in order to improving the quality of life of these women.

Analysis of Global DNA Methylation in Irradiated Fig Selections

American Journal of Plant Sciences 2015年第14期6卷 2257-2262页

作者： maria Gabriela Fontanetti Rodrigues Murilo Racy soares Ester Silveira ramos Silvana Giuliatti Departament do Genetics at the University of Sao Paulo Medical School University of S&atilde o Paulo Ribeir&atilde o Preto Brazil

Fruits from fig tree (Ficus carica L.) are economically important worldwide, and rank among the top 20 fruits exported by Brazil. However, due to particular features in its floral structure, classical plant breeding procedures that involve hybridization are not possible. Thus, genetic improvement of figs by using mutagens is an important line of research. In this study, five fig selections based on their interesting agronomic features were used. Genetic modifications associated with mutations were not detected by molecular markers. Therefore, it was suggested that certain phenotypes could have resulted from epigenetic modifications. The best characterized epigenetic modification is DNA methylation, which can switch genes on or off by acting as a signal. After epigenetic polymorphisms were identified by methylation sensitive amplified polymorphism (MSAP) molecular markers, we quantified the level of DNA methylation in fig selections irradiated with gamma rays and compared it to levels in the commercial cultivar “Roxo-de-Valinhos.” This was achieved by analyzing the global methylation using an Imprint Methylated DNA Quantification kit. The results showed that there were significant differences in global methylation following different treatments, indicating that irradiation was an abiotic factor that could alter the epigenome of plants. Since the material used as a control was also found to be methylated, demethylation of the polymorphic genomic material might account for the phenotypic variations observed among different treatment groups. These results suggest that irradiation is an external factor that is capable of altering epigenetic patterns.

Background: Skin reactions and musculoskeletal injuries caused by intramuscular injection are an increased risk for skin and soft tissue infections and may culminate in sepsis. Objective: To describe the history of an elderly patient who developed a lesion in her right arm after home administration of intramuscular iron injection in this arm and its outcome. Methods: This is a case report of a patient who participated in a study in an intensive care unit. Results: This study describes a 65-year-old patient with multiple comorbidities who was admitted to the hospital complaining of pain for two months and difficulty in moving her right shoulder associated with skin and soft tissue infections in her right arm after intramuscular iron administration by a relative for the treatment of multifactorial anemia and refractory melena. The patient worsened her general condition and was transferred to the intensive care unit. Despite the therapy instituted, the patient developed sepsis of cutaneous origin, multiple organ dysfunction, and death. Conclusions: The administration of intramuscular medication requires the participation of qualified professionals, such as nurses, mainly within the scope of the Brazilian public health system which commonly comprises patients in a context of vulnerability.

Pulmonary Tuberculosis Associated with Socioeconomic Vulnerability and Ineffective Support Network: Case Report

Tuberculosis is one of the 10 leading causes of death in the world. Its symptoms include fever, malaise, weakness, weight loss, chest pain, cough, expectoration, shortness of breath and sepsis, which is its most frequent complication. Due to these symptoms, many patients with tuberculosis require admission to the Intensive Care Unit, where they usually are placed on mechanical ventilation. Tuberculosis is more prevalent in the population in situations of social and economic vulnerability. The main factors that interfere with adherence to treatment and the prognosis of these patients are the patient’s support network and their socioeconomic status. We present the following report of a long-time smoker patient, with chronic kidney disease and previous treatment for tuberculosis, who was brought to the emergency room due to lowering of the sensorium, and was immediately placed on mechanical ventilation. The tests suggested sepsis with a respiratory focus, so a search for Alcohol-Acid-Resistant Bacillus was carried out, with a positive result. The patient was transferred to the Intensive Care Unit due to tachycardia and acute respiratory failure. The patient was a smoker with a high tobacco load, chronic kidney disease, in addition to precarious economic, educational and self-care conditions. This report shows that patients with tuberculosis and its complications can be stabilized through known pharmacological treatment. However, the most effective measure to interrupt the transmission of the disease remains the early diagnosis and the provision of adequate treatment, with guidelines aimed at the cessation of harmful habits, such as smoking.

Cellulose nanocrystals (NCC) and cellulose nanofibrils (CNF) were obtained by a single step process, with synergy between 64% sulfuric acid hydrolysis and high shear from ultra-turrax stirring, which is an advantageous process for disintegrating cellulose microcrystalline and also may improve the hydrolysis process. The surface modification on the cellulose was performed by the sol-gel process, in which the sulfate groups from hydrolysis were replaced by nanoparticles of zinc oxide, which led to the increase of up to 54°C Tonset, according to thermogravimetric analysis (TGA) results. The morphology and crystallinity degree were characterized by Helium Ion Microscopy (HIM), atomic force microscopy (AFM) and X-ray diffraction. In addition, the ZnO band was observed in Fourier transform infrared spectroscopy, furthermore, the change in the zeta potential confirmed the cellulose modification. The changes in the values of proton spin-spin relaxation time for the systems showing the confined hydrogen in the rigid domains, confirmed the results observed with the aforementioned techniques, for both cellulose after hydrolysis and ZnO modified cellulose, suggesting that ZnO disrupted crystal formation in cellulose.
