Profile of victims of occupational accidents involving exposure to biological material notified in the city of Palmas, state of Tocantins, Brazil.

Introduction: An occupational accident involving exposure to biological material is characterized by worker's contact with organic fluids during the working day and in Brazil it is considered a condition of compulsory declaration.

Objectives: To analyze the profile of victims of occupational accident involving exposure to biological material in the city of Palmas, state of Tocantins, from 2010 to 2020.

Methods: Descriptive cross-sectional study using the Notifiable Diseases Information System.

Are men more likely to have serious occupational accidents? Findings of reported cases in Palmas, northern Brazil.

To ascertain whether male workers from Palmas, Tocantins state, northern Brazil, are more likely to have occupational accidents compared to female workers, all cases of serious occupational accidents reported between 2009 and 2019 were extracted from the Brazilian Notifiable Diseases Information System and compared with the economically active population according to sex. Men were found to be 6.2 times more likely to have a serious occupational accident compared to women.

Risk factors for stress in professionals at the North emergency care unit in Palmas, Tocantins, Brazil.

Introduction: Emergency care units provide intermediate complexity care services, are open 24 hours a day, and are frequently required to attend to high levels of demand, especially so during the Covid-19 pandemic. On-duty shift work at emergency care units is highly conducive to causing excessive stress.

Objectives: To identify the risk factors for excessive stress among workers at the North emergency care unit, in Palmas, Tocantins, Brazil.

Co-existing monophasic teratoma and uterine adenocarcinoma in a female dog.

Ovarian teratomas are occasionally reported in dogs; the rarest type is the monophasic teratoma, composed of tissues originating from only one germ layer. Canine endometrial adenocarcinomas are also rare in dogs and mainly affect geriatric females. This report describes the case of co-existing ovarian teratoma and uterine adenocarcinoma in a 10-year-old nulliparous female Boxer presented with lethargy, anorexia and purulent vaginal discharge.

Towards the Development of a Low-Cost Device for the Detection of Explosives Vapors by Fluorescence Quenching of Conjugated Polymers in Solid Matrices.

Conjugated polymers (CPs) have proved to be promising chemosensory materials for detecting nitroaromatic explosives vapors, as they quickly convert a chemical interaction into an easily-measured high-sensitivity optical output. The nitroaromatic analytes are strongly electron-deficient, whereas the conjugated polymer sensing materials are electron-rich. As a result, the photoexcitation of the CP is followed by electron transfer to the nitroaromatic analyte, resulting in a quenching of the light-emission from the conjugated polymer.

Numerical study of the influence of electrode arrangements in electrokinetic remediation technique.

The effectiveness of electrokinetic remediation for soils depends on several factors such as the arrangement and shape of electrodes. This paper presents a numerical study on external electrostatic field generated by seven different electrode configurations in any unbounded two-dimensional domain. The boundary condition at infinity for the voltage is approximated by the iterative algorithm that expands the domain till the limit of the specified tolerance (threshold value).

Uterine Extramedullary Plasmacytoma as a Primary Manifestation of Multiple Myeloma.

The association between plasmacytomas and multiple myeloma (MM) is well-described, and in about one third of the cases of plasmacytoma the additional study will lead to the diagnosis of MM. The finding of plasmacytomas in the genital tract is extremely rare, with sparse cases described in the literature, and these cases pose a challenge regarding the optimal guidance and treatment. This paper describes a case of uterine extramedullary plasmacytoma in a 79-year-old woman with complaints of postmenopausal abnormal uterine bleeding.

Linking Learning Contexts: The Relationship between Students' Civic and Political Experiences and Their Self-Regulation in School.

This paper considers the relationship between self-regulation strategies and youth civic and political experiences, assuming that out-of-school learning can foster metacognition. The study is based on a sample of 732 Portuguese students from grades 8 and 11. Results show that the quality of civic and political participation experiences, together with academic self-efficacy, are significant predictors of young people's self-regulation, particularly regarding cognitive and metacognitive strategies (elaboration and critical thinking).

Bladder metastasis of gastric adenocarcinoma. Report of 2 cases and bibliographic review.

Objective: Metastases to the urinary bladder are rare, representing less than 2% of bladder tumors. We report two cases of bladder involvement by primary gastric adenocarcinoma and perform a bibliographic review of the literature on this subject.

Methods: A search for published data was performed in the PubMed database using the key words "bladder", "secondary malignant tumors" and "metastatic gastric carcinoma".

[Concomitant syphilitic aneurysms of the thoracic and abdominal aorta. Case report].

The aneurismatic aortic disease is one of the most frequent conditions challenging the vascular surgeon. It can be caused by atherosclerosis, vasculitis, trauma, infection or others. The treatment, even when elective, can be associated to high rates of morbid-mortality, related to the etiology, anatomic location and type of treatment.

[Strangulated urethral prolapse. Case report].

Objective: We report a case of strangulated urethral prolapse.

Method/results: A 62-year-old female patient presents to the emergency department with complaints of a bleeding vaginal mass, pain referred to the vaginal introitus and dysu-ria. After being diagnosed with a strangulated urethral pro-lapse, surgical excision of the prolapsed urethra was performed.

[Bladder adenocarcinoma. Case report].

Objective: Primary bladder adenocarcinoma is a rare entity. We performed a review of the literature on this subject and present a clinical case.

Method/results: A 74 year old female patient presents to the emergency department with complaints of gross hematúria not accompanied by lower urinary tract symptoms.
