Item Correlação entre índice-tornozelo braço e medidas de termografia em pacientes com doença arterial periférica(Universidade Brasil, 2020) Abreu, Jesus Antônio de Carvalho; Martin, Airton Abrahão; Oliveira, Rauirys Alencar dePurpose: to correlate the ankle-brachial index (ABI) and photographic thermography (PT) in patients with peripheral arterial disease (PAD). Methods: PT was performed at the foot level, and ABI was measured in 72 lower limbs of patients with PAD divided into calcified and non-calcified artery groups. The non calcified artery group was classified by PAD severity as asymptomatic, mild, moderate, and severe. The calcified artery group comprised patients with ABI greater than 1.4. The Fisher’s exact test was used for categorical data and the Wilcoxon test for numeric data. Results: the Spearman’s correlation between ABI and PT according to the mean foot sole temperature showed strong correlation (R=0.7) in patients without lower limb artery calcification. R2 indicated that the ABI influenced the foot temperature by 48.8%. Linear regression presented a predictor equation equal to Y=3.296*X+29.75, where ABI (X) can be predicted based on temperature values. The Spearman’s correlation test showed no significance (p=0.2174) in patients with artery calcification, showing no correlation between ABI and mean foot sole temperature. However, the Kruskal-Wallis test with post-hoc analysis with Dunn’s test for multiple comparisons showed that the mean foot sole temperature is lower in patients with artery calcification than in asymptomatic patients. Conclusion: PT has a strong correlation with ABI in patients with non-calcified arteries. Due to its strong correlation with ITB, photographic thermography is a reliable method for evaluating patients with PAD in non-calcified arteries.Item Avaliação da resposta termal do recém-nascido pré-termo submetido à estimulação tátil e cinestésica no ambiente não termocontrolado(Universidade Brasil, 2022) Falcão, Laysa Monte Aguiar; Parizotto, Nivaldo Antonio; Lima, Andréa Conceição GomesTactile and kinesthetic stimulation (TKS) is considered a low-cost, easy-to-apply, non invasive and non-pharmacological tool that assists in the care and evolution of premature newborns who need to remain hospitalized in a Neonatal Intensive Care Unit (NICU). However, there are few studies that address the benefits of TKS outside a thermally controlled environment such as the NICU. Thus, the present study aimed to evaluate the thermal response of preterm newborns (PTNB) submitted to the application of TKS in a non-thermocontrolled environment. Experimental clinical research, cross-sectional, including PTNB's with gestational age between 32 and 36 weeks, hospitalized in rooming-in, minimum weight of 1,300g, clinical progression to hospital discharge and whose guardians’ accepted participation in the research. The non-inclusion criteria consisted of clinical situations that prevented or hindered the application of TKS. To collect information relevant to the research, analysis of medical records and data recorded in a form prepared by the researcher was used. The research consisted of two pilot protocols and a definitive protocol. In the definitive protocol, image capture was performed with the forehead as the region of interest, a standard distance of 80cm and TKS lasting 15 minutes with handling divided between 10 minutes of tactile stimulation and 5 minutes of kinesthetic stimulation. Room, frontal and axillary temperatures were measured before and after TKS application. The Brazelton Scale was used in order to analyze the behavior of neonates during the TKS. Sample of 86 PTNB's, 40 belonging to the definitive protocol and with percentages of 72.5% of late preterms and 92.5% of low weight. The ambient temperature was maintained with a non-significant variation of +_ 1°C. Axillary and frontal temperature also without significant variations in the comparison between before and after TKS. It is possible to apply TKS in PTNB's in a non-thermocontrolled environment. The handling and time protocol used in this research is suggested as safe.
