Remote heart rate monitoring - Assessment of the Facereader rPPg by Noldus.

Remote photoplethysmography (rPPG) allows contactless monitoring of human cardiac activity through a video camera. In this study, we assessed the accuracy and precision for heart rate measurements of the only consumer product available on the market, namely the FacereaderTM rPPG by Noldus, with respect to a gold standard electrocardiograph. Twenty-four healthy participants were asked to sit in front of a computer screen and alternate two periods of rest with two stress tests (i.

GENDER, AGE, ENDOSCOPIC FINDINGS, UREASE AND HELICOBACTER PYLORI : ALL UNCORRELATED WITHIN A SAMPLE OF A HIGH GASTRIC CANCER PREVALENCE POPULATION IN AMAZON.

Background: It is widely assumed that gender, age, gastritis and Helicobacter pylori , all have some degree of correlation and, therefore, can synergistically lead to the development of gastric cancer.

Objective: In this cross-sectional study, we expected to observe the above mentioned correlation in the analysis of medical records of 67 patients of both sexes (female, n=44), mean age ± standard deviation: 41±12 years old, all from Belém (capital of Pará State, Brazilian Amazon), a city historically known as one with the highest gastric cancer prevalence in this country.

Methods: All patients were submitted to upper gastrointestinal endoscopy for gastric biopsy histopathological analysis and rapid urease test.

Assessment of the Fitbit Charge 2 for monitoring heart rate.

Fitness trackers are devices or applications for monitoring and tracking fitness-related metrics such as distance walked or run, calorie consumption, quality of sleep and heart rate. Since accurate heart rate monitoring is essential in fitness training, the objective of this study was to assess the accuracy and precision of the Fitbit Charge 2 for measuring heart rate with respect to a gold standard electrocardiograph. Fifteen healthy participants were asked to ride a stationary bike for 10 minutes and their heart rate was simultaneously recorded from each device.

[Metastatic gastric neoplasm in the spermatic cord: report of a case].

The Authors report a case of a 69-year-old male patient recently operated on for a gastric cancer who developed metastasis to the right spermatic cord. They emphasize the rarity of this condition and then go on to review the international literature on the subject.

Vesicoureteral reflux after kidney transplantation: clinical significance in the medium to long-term.

103 patients who received a cyclosporine-treated primary cadaver kidney transplant (TX) at our center between 1985 and 1989, whose graft survived for more than 1 year and who accepted to undergo voiding cystography after TX were analyzed and grouped according to the highest grade (regardless to whether active or passive) of vesicourteral reflux (VUR): group 0, absent (n = 14); group 1-2, grade I or II (n = 62); group 3, grade III (n = 27). Patient follow-up ranged from 5 to 10 (median 7) years. Patient and graft survivals and prevalence of hypertension (defined as the persistent need of antihypertensive therapy), did not differ significantly between groups (Mantel-Cox test p: n.
