- A promising and low-cost prototype to evaluate the motor pattern of nutritive and non-nutritive suction in newbornsPublication . Cunha, Manuel; Barreiros, João; Pereira, José Miguel Costa Dias; Viegas, Vítor; Banha, Carlos; Diniz, Ana; Pereira, Margarida; Barroso, Rosalina; Carreiro, HelenaIntroduction: Non-nutritive sucking (NNS) plays an important role in stabilizing the preterm, providing oral muscle training opportunity for nutritive sucking (NS). We aim to determine if the prototype tested allows a precise evaluation of suction pattern characteristics (rhythmic structure and pressure). We also aim to investigate the role of maturation in the variation of NNS an NS pattern in preterm infants. Methods: The patented prototype is non-invasive, low-cost and easily applicable to clinical ecological practice, measures the pressure exerted on a pacifier in newborn’s mouth. Samples were acquired continuously during a 10-minute period in 12 preterm (mean gestational age [GA] 29.9 ± 1.6 weeks) and 4 term neonates (GA 39.5 ± 1.4 weeks). Bursts, suctions per burst, pauses, suction frequency and pressure were analyzed to describe temporal structure and dynamic characteristics of NNS. Results: The NNS pattern was characterized by bursts duration 4.3 ± 2.2 s, number of sucks per burst 7.4 ± 3.2, sucking frequency 2.1 ± 0.4 Hz and sucking pressure 10.3 ± 4.5 mmHg. There were significant differences between the preterm and term groups in NNS sucking frequency (2.1 Hz vs 1.6 Hz; p = 0.008). Conclusion: The device is non-invasive and can easily be used in clinical practice in low GA newborns, in an ecological environment. It allows the evaluation of NNS patterns maturation and, at the same time, the use of the device pacifier promotes NNS, which is important in the process of acquiring feeding autonomy in preterm infants.
- The immediate effects of a dynamic orthosis on gait patterns in children with unilateral spastic cerebral palsy: a kinematic analysisPublication . Martins, Maria Elisabete; Cordovil, Rita; Oliveira, Raúl; Pinho, Joana; Diniz, Ana; Vaz, João RThis study analyzes the immediate effects of wearing a Therasuit on sagittal plane lower limb angular displacements during gait in children with unilateral spastic cerebral palsy (US-CP). Seven participants (median age = 7.00 years; ranging from 5.83 to 9.00 years) with US-CP, levels I and II of the Gross Motor Function Classification System, were assessed with kinematic gait analysis in three different conditions: (A) Baseline; (B) Therasuit without elastics and (C) Therasuit with elastics. Significant improvements were observed at the hip joint of both lower limbs during most of the gait cycle in participants wearing a Therasuit, including a decrease in the flexion pattern at the initial contact and swing phase in both lower limbs, and an increase in the extension pattern in the paretic lower limb during the stance phase. At the knee joint in the paretic lower limb, significant differences were found between the baseline and Therasuit with elastics conditions on the knee angle at initial contact, and between baseline and both Therasuit conditions on the flexion angle at swing phase. However, the inter-individual variability in kinematic patterns at the knee joint was high. At the ankle joint, decreased plantar flexion at initial contact and increased dorsiflexion during stance and swing phases were observed at the Therasuit with elastics condition, helping to correct the equinus-foot in the paretic lower limb during the whole gait cycle. The Z-values showed large effect sizes particularly for most of the angular hip variables in both lower limbs and for the angular ankle variables in the paretic lower limb. The Therasuit seems to have some positive immediate effects on gait kinematics in children with spastic unilateral cerebral palsy by providing a more functional and safer gait pattern. Future investigations with larger samples are recommended to further support these findings.
- Trabalho Livre nº 35 - Práticas de Notificação e Prevenção de UPP: a experiência de uma unidade de MedicinaPublication . Guerreiro, Rui; Diniz, Ana; Miranda, Marta; Henriques, Solange; Costa, JoséA prevalência de úlceras por pressão (UPP) nos serviços de medicina é elevada, sendo recomendado o desenho de intervenções preventivas. Decorrente do processo de implementação do sistema de notificação de incidentes de segurança do doente no CHULC, a unidade de Medicina 1.2, notifica incidentes de UPP intra e extra-hospitalares desde 2008. Neste sentido, tem desenvolvido estratégias relativas à análise das práticas de prevenção, tal como recomendado no 7º objectivo estratégico do PNSD 2015-2020.
