Magnetically Guided Microcatheter for Targeted Injection of Magnetic Particle Swarms.

The initial delivery of small-scale magnetic devices such as microrobots is a key, but often overlooked, aspect for their use in clinical applications. The deployment of these devices within the dynamic environment of the human body presents significant challenges due to their dispersion caused by circulatory flows. Here, a method is introduced to effectively deliver a swarm of magnetic nanoparticles in fluidic flows.

Assessment of the yellow fever outbreak in Angola from December 2015 through December 2016: A retrospective study.

Background And Aims: The acute tropical infectious disease known as yellow fever (YF) is caused by an arbovirus and is characterized by fever, jaundice, hemorrhage, headache, muscle pain, nausea, vomiting, and fatigue. Angola experienced a yellow fever virus (YFV) outbreak that was documented in December 2015. However, little is known about the outcome of this outbreak.

Effect of Systemic and Auricular Acupuncture with a 2/100 Hz Frequency and Nogier Frequency in Fibromyalgia: a Randomized Clinical Trial, Pilot Study.

Background: Fibromyalgia is a syndrome of chronic, generalized muscular pain, accompanied by sleep disturbances, fatigue and cardic autonomic dysfunction that will affect the quality of life. There is currently no gold standard treatment. There are limitations of studies with electroacupuncture in auricular acupuncture.

Pulsed Laser Acupuncture in the Treatment of Pain and Heart Rate Variability in Fibromyalgia Patients: A Pilot Randomized Clinical Trial.

Laser acupuncture (LA) is a medically approved treatment for chronic pain, especially fibromyalgia. It is widely known that all pain is related to autonomic modulation, which may influence heart rate variability (HRV). There are robust studies in the literature on the effect of LA with continuous frequency on musculoskeletal pain and autonomic modulation.

Topical antiedematogenic and anti-inflammatory effect of Scutia buxifolia Reissek gel and stability study.

Scutia buxifolia Reissek (Rhamnaceae), popularly known in Brazil as "coronilha", is a plant species used in folk medicine for several disorders, including inflammation. However, no studies have been done with this species to confirm its topical anti-inflammatory action. In this study we evaluate the topical antiedematogenic and anti-inflammatory effects of the gel containing crude extract (CE) and the gel containing ethyl acetate (EtOAc) fraction of S.

Tabernaemontana catharinensis ethyl acetate fraction presents antinociceptive activity without causing toxicological effects in mice.

Ethnopharmacological Relevance: Tabernaemontana catharinensis (Apocynaceae) is a medicinal plant used for the treatment of painful and inflammatory disorders. Here, we investigated the antinociceptive potential of the ethyl acetate fraction (Eta) from T. catharinensis leaves and assessed its toxic effects in mice to validate its popular use.

Underrecognition of Dengue during 2013 Epidemic in Luanda, Angola.

During the 2013 dengue epidemic in Luanda, Angola, 811 dengue rapid diagnostic test-positive cases were reported to the Ministry of Health. To better understand the magnitude of the epidemic and identify risk factors for dengue virus (DENV) infection, we conducted cluster surveys around households of case-patients and randomly selected households 6 weeks after the peak of the epidemic. Of 173 case cluster participants, 16 (9%) exhibited evidence of recent DENV infection.

[Assessment of bariatric surgery results].

The objective was to evaluate the results of bariatric surgery in patients in the late postoperative period using the Bariatric Analysis and Reporting Outcome System (BAROS). This cross-sectional study was conducted from November 2011 to June 2012 at a hospital in the state of Ceará, Brazil. Data were collected from 92 patients using the BAROS protocol, which analyzes weight loss, improved comorbidities, complications, reoperations and Quality of Life (QoL).

[Nursing diagnoses, related factors and risk factors during the postoperative period following bariatric surgery].

The objective was to identify the main diagnoses, related factors and risk factors regarding the cardiovascular/pulmonary responses class proposed by NANDA version 2009-2011. This case series descriptive study was performed with twenty patients who underwent bariatric surgery in a public hospital in Fortaleza-CE, Brazil. Data were collected by two intensive care unit nurse specialists through interviews, physical examinations and the reviewing of medical records, and analyzed through descriptive statistics and cross-mapping.

Effects of butane-2,3-dione thiosemicarbazone oxime on testicular damage induced by cadmium in mice.

Our group of studies investigated the action of butane-2,3-dione thiosemicarbazone oxime against the testicular damage caused by cadmium chloride (CdCl(2)) in mice. Mice received a single injection of CdCl(2 )(5 mg/kg, intraperitoneally) and, after thirty minutes, the oxime (10 mg/kg, subcutaneously) was administered. Twenty four hours after the last administration, the animals were killed by cervical dislocation and the testes and serum were removed for analysis.

Epidemiological and clinical aspects of urinary tract infection in community-dwelling elderly women.

Background: Urinary tract infections (UTIs) in elderly patients can be a complex problem in terms of approach to diagnosis, treatment, and prevention, because the patients often present nonspecific symptoms. The epidemiological and clinical characteristics of UTI in elderly women were studied, in order to make early diagnosis and prevent serious clinical complications secondary to UTI.

Methods: This was a prospective population-based study, with elderly women, during their first medical office visit.

[Juvenile obesity with a focus on health promotion: integrative review].

This integrative review summarizes nursing researches that contribute to study juvenile obesity with a focus on health promotion. 20 articles were identified in a bibliographical survey that followed the criteria: date, language, and the descriptors: nursing, adolescent, obesity and health promotion. The Pediatric Nursing Journal published seven of these papers (35%).

Effect of salinity and inorganic nitrogen concentrations on nitrification and denitrification rates in intertidal sediments and rocky biofilms of the Douro River estuary, Portugal.

The regulatory effects of salinity and inorganic nitrogen compounds on nitrification and denitrification were studied in intertidal sandy sediments and rocky biofilms in the Douro River estuary, Portugal, over a 12-month period. Nitrification and denitrification rates were measured in slurries of field samples and enrichment experiments using the difluoromethane and the acetylene inhibition techniques, respectively. Salinity did not regulate denitrification in either environment, suggesting that halotolerant bacteria dominated the denitrifier communities.
