Kinetic and temporospatial parameters in male and female cats walking over a pressure sensing walkway

Background: Several factors may influence kinetic data measurements, including body conformation and body mass. In addition, gender differences in gait pattern have been observed in healthy humans. Therefore, the aim of this study was to compare the kinetic and temporospatial parameters in clinically healthy male and female cats using a pressure-sensitive walkway. Eighteen crossbreed adult cats were divided into two groups: G1 had ten male cats (nine neutered) aged from 1 to 4 years and body mass 3.1-6.8 kg; G2 had eight spayed female cats, aged from 1 to 6 years and body mass 3.3-4.75 kg. The data from the first five valid trials were collected for each cat. A trial was considered valid if the cat maintained a velocity between 0.54-0.74 m/s and acceleration from -0.20 to 0.20 m/s2. The peak vertical force (PVF), vertical impulse (VI), gait cycle time, stance time, swing time, stride length, and percentage body weight distribution among the four limbs were determined. In addition, the lengths of each forelimb and each hind limb were measured using a tape with the animal standing.Results: No significant differences were observed in each group in either the forelimbs or the hind limbs or between the left and right sides for any of the variables. For both groups, the PVF (%BW), the VI, and the percentage body weight distribution were higher at the forelimbs than the hind limbs. The stride length was larger for males; however, the other kinetic and temporospatial variables did not show any statistically significant differences between the groups. The lengths of the forelimbs and hind limbs were larger in the male cats. There was a significant moderate positive correlation between the stride length and the length of the limbs.Conclusions: In conclusion, the only difference observed between male and female cats was the stride length, and this was due to the greater body size of male cats. This difference did not affect other temporospatial or kinetics variables. © 2013 Verdugo et al.; licensee BioMed Central Ltd.

Conjunctival flora, Schirmer's tear test, intraocular pressure, and conjunctival cytology in neotropical primates from Salvador, Brazil

Background: This study aimed to establish reference values for selected ophthalmic diagnostic tests in healthy neotropical primates from Salvador, Brazil. Methods: A total of 73 intact adults, including Callithrix jacchus (n = 31), Callithrix penicillata (n = 8), Cebus sp. (n = 22), and Cebus xanthosternos (n = 9) were used to evaluate the normal conjunctival bacterial flora. Cebus xanthosternos (n = 12) were used to evaluate tear production with Schirmer's tear test (STT), intraocular pressure (IOP), and conjunctival cytology. Results: For all animals evaluated, Gram-positive bacteria were predominant. Results of the diagnostic tests in Cebus xanthosternos were as follows: STT: 14.92 ± 5.46 mm/minutes, IOP: 19.62 ± 4.57 mmHg, and conjunctival cytology revealed intermediate squamous epithelial cells in great quantities. Conclusions: These ophthalmic reference values will be particularly useful to diagnose discrete or unusual pathological changes in the neotropical primates eye. © 2013 John Wiley & Sons A/S.

Diabetic peripheral neuropathy in ankles and feet: muscle strength and plantar pressure

This study aims to evaluate and correlate the vascular, sensory and motor components related to the plantar surface in individuals with diabetic peripheral neuropathy. 68 patients were categorized into two groups: 28 in the neuropathic group and 40 in the control group. In each patient, we assessed: circulation and peripheral perfusion of the lower limbs; somatosensory sensitivity; ankle muscle strength; and pressure on the plantar surface in static, dynamic and gait states. We used the Mann-Whitney test and analysis of variance (ANOVA and MANOVA) for comparison between groups, and performed Pearson and Spearman linear correlations amongst the variables (P < 0.05). The somatosensory sensitivity, peripheral circulation and ankle muscle strength were reduced in the neuropathic group. In full peak plantar pressures, no differences were seen between groups, but differences did appear when the foot surface was divided into regions (forefoot, midfoot and hindfoot). In the static condition, the plantar surface area was greater in the neuropathic group. In the dynamic state, peak pressures in the neuropathic group, were higher in the forefoot and lower in the hindfoot, as well as lower in the hindfoot during gait. There were positive or negative correlations between the sensitivity deficit, dorsal ankle flexor strength, plantar surface area, and peak pressure by plantar region. The sensitivity deficit contributed to the increased plantar surface area.

Determinant factors for mortality of patients receiving mechanical ventilation and effects of a protocol muscle training in weaning

Introduction: Prognostic factors are used in the Intensive Care Unit (ICU) to predict morbidity and mortality , especially in patients on mechanical ventilation (MV ) . Training protocols are used in MV patients with the aim of promoting the success of the weaning process. Objective: To assess which variables determine the outcome of patients undergoing mechanical ventilation and compare the effects of two protocols for weaning. Method: Patients under MV for more than 48 hours had collected the following information: sex, age , ideal weight, height , Acute Physiology and Chronic Health Evaluation (APACHE II), risk of mortality, Glasgow Coma Scale (GCS) and index Quick and perfunctory (IRRS) breathing. Patients with unsuccessful weaning performed one of weaning protocols: Progressive T - tube or tube - T + Threshold ® IMT. Patients were compared for outcome (death or non- death in the ICU ) and the protocols through the t test or Mann-Whitney test was considered significant when P <0.05. Results: Of 128 patients evaluated 56.25% were men, the mean age was 60.05 ± 17.85 years and 40.62 % patients died, and they had higher APACHE II scores, mortality risk, time VM and IRRS GCS and the lower value (p<0.05). The age, initial and final maximal inspiratory pressure, time of weaning and duration of MV was similar between protocols. Conclusion: The study suggests that the GCS, APACHE II risk of mortality, length of MV and IRRS variables determined the evolution of MV patients in this sample. Not found differences in the variables studied when comparing the two methods of weaning.

Diastolic blood pressure associated with accumulated work time among drivers and collectors

The relationship between diastolic blood pressure and the variables total cumulative working time and age was examined by regression analysis. The study was carried out among 839 bus drivers and conductors, users of an occupational health center in Campinas, S. Paulo State, Brazil. The main results were a positive association between diastolic blood pressure and cumulative working time, as well as an interaction between this variable and the bus worker's age.
