- ItemAcesso aberto (Open Access)Avaliação do desenvolvimento neuromotor de lactentes prematuros e fatores biológicos e socioeconômicos(Universidade Federal de São Paulo (UNIFESP), 2010) Esteves, Jéssica Pedrassa [UNIFESP]; Sá, Cristina dos Santos Cardoso de [UNIFESP]; Carvalho, Raquel de Paula [UNIFESP]; http://lattes.cnpq.br/7980384093582831; http://lattes.cnpq.br/9259523998158401; http://lattes.cnpq.br/5884000935277552; Universidade Federal de São Paulo (UNIFESP)Nas últimas décadas o avanço tecnológico alcançado no campo da assistência neonatal contribuiu notavelmente para a redução das taxas de mortalidade de recém nascidos prétermos (RNPT) favorecendo os índices de sobrevida. Tais bebês, porém, têm maior probabilidade de apresentar atrasos do desenvolvimento neuromotor. Estas crianças estão propensas aos riscos biológicos, ao nascimento, e aos riscos socieconômicos. E assim podem apresentar dificuldades para adaptar-se à vida extra-uterina devido à imaturidade dos diversos sistemas orgânicos e aos riscos os quais estão expostos. O objetivo deste estudo foi caracterizar o desenvolvimento neuromotor de lactentes prematuros e analisar a influência de fatores biológicos e socioeconômicos na aquisição motora destas crianças. Cada bebê foi avaliado quanto ao seu desempenho motor pela escala canadense Alberta Infant Motor Scale (AIMS) e foi utilizado questionário com os responsáveis, contendo identificação do neonato, informações sobre gestação, parto e pós-parto, as complicações clínicas. A amostra foi composta por 30 bebês de ambos os gêneros, nascidos com idade gestacional inferior a 37 semanas gestacionais divididos em dois grupos segundo a IG: limítrofe e moderado. Na primeira avaliação neuromotora 79% dos pré-termos limítrofes situou-se entre 50-75% somente 15% situaram-se no percentil 10 apresentando desempenho motor suspeito. Enquanto que 70% dos bebês do grupo moderado permaneceram no percentil 50. No presente estudo não foram encontrados atrasos significativos no desempenho motor grosso de bebês pré-termos avaliados pela AIMS. Os fatores socioeconômicos e biológicos, exceto o tempo de internação em UTI (p=0,055) não influenciaram o desenvolvimento neuromotor dos bebês no que se refere à avaliação inicial
- ItemSomente MetadadadosDesenvolvimento de uma balança microcontrolada de baixo custo para unidades de terapia intensiva neonatal(Universidade Federal de São Paulo (UNIFESP), 2020-07-24) Hua, Lin Hung [UNIFESP]; Martins, Luiz Eduardo Galvao [UNIFESP]; Universidade Federal de São PauloIntroduction: The evolution of the technology applied to the care of preterm babies in Neonatal Intensive Care Units was a great impact factor to reduce the mortality of these patients. Materials, medicine and equipment technologies made possible increase the survival rates. Diseases associated with prematurity and prolonged hospitalization, such as Respiratory Distress Syndrome and infections contribute to the risks of sequels. There are other risk factors that are inherent to daily care: hypothermia, oscillation of oxygenation and blood pressure, discomfort, pain and environmental conditions of the unit such as lighting and excessive noise. Organizing care to reduce premature patient handling, decreasing monitor alarm volume, establishing quiet times to respect sleep are environmental control actions that favor the clinical stability and development of preterm babies. One of the routine procedures in these units is weighing patients. The weighing method adopted in most Brazilian hospitals increases the risk of hypothermia, stress, clinical instability and fall. Objective: to develop a low-cost neonatal scale prototype to modify the weighing process. Methods: a prospective study, the prototype development was through a convention established between two institutions: ICT/Unifesp and Dr. José de Carvalho Florence Municipal Hospital. The prototype was mounted in the ICT/Unifesp laboratory and patient tests were performed at the Hospital. The prototype tests with patient were carry out at Hospital Municipal Dr. José de Carvalho Florence. The weighing tests with the prototype lasted for 14 days. Results: professionals did not have difficulties to use the prototype during the tests period, the equipment did not present any problems. The prototype allows weighing patients without removing them from the incubator. The developed prototype cost is 14.1% of the value of the similar weighing scale available on the Brazilian market. Conclusions: it is possible to change the weighing process with low cost equipment, make easier to spread the method, for less exposure to risk factors that impair the neurodevelopment in premature infants.
- ItemSomente MetadadadosInfluência da duração do contato pele a pele sobre o sono e parâmetros fisiológicos de recém-nascidos pré-termo(Universidade Federal de São Paulo (UNIFESP), 2020-11-26) Pinto, Claudia Machado Alves [UNIFESP]; Avelar, Ariane Ferreira Machado [UNIFESP]; Universidade Federal de São PauloIntroduction: Improving the sleep-wake pattern and stabilizing the vital signs of preterm newborns (PTNB) are benefits related to skin-to-skin contact with their mother or father, with a positive impact on brain development, maturation and repair , behavioral, cognitive and motor of the newborn. However, the duration of skin-to-skin contact is still not clearly established in order to achieve the expected positive results during hospitalization and discharge of PTNB. Objective: To investigate the influence of the duration of skin-to-skin contact on sleep and physiological parameters of preterm newborns and the maternal and neonatal characteristics that may interfere with the duration of this contact. Casuistry and method: Cross-sectional study, developed with preterm newborns, weighing less than 2,000 grams and able to perform skin-to-skin contact (CPP) at the Conventional Neonatal Intermediate Care Unit of a public maternity hospital in the Western Brazilian Amazon. The convenience sample consisted of 36 PTNB and 30 mothers. Data collection took place from April to October 2018. Sociodemographic, reproductive and obstetric maternal, biological and neonatal vitality variables, those related to skin-to-skin contact and their duration, physiological and behavioral parameters were investigated. The physiological parameters of newborns (NB) were recorded before, during and after a single session of skin-to-skin contact, and the mother's temperature was recorded before and after. The behavioral responses presented by the newborns during the CPP were filmed in real time, and the predominant state of the behavior was recorded at the end of each 10-second recording period. The differentiation of the sleep-wake states of PTNBs was performed based on the definitions of an accepted observational biobehavioral assessment method and classified as sleep, wakefulness and transition. Results: Skin-to-skin contact occurred for a median time of 2.12 hours (1st quartile: 1.65; 3rd quartile: 2.99), with newborns between 26 and 31 weeks of gestational age and weight between 980 and 2,000 grams at birth. Most mothers (55.6%) remained in CPP for more than 2 hours. Statistically significant differences were identified in the respiratory rate of the PTNB and maternal axillary temperature between the values before and after the CPP and the neonatal heart rate before the end of the CPP (p⦤0.05). With regard to behavior, the duration of CPP did not significantly influence the sleep time of PTNB, but it was possible to observe that NBs who stayed in contact longer spent more time sleeping. Conclusion: our study was unable to identify the effect of CPP duration on sleep in this sample of preterm newborns. Monitoring the behavioral state for a longer period can provide significant insights. As for the physiological parameters, the CPP promoted an increase in the neonatal respiratory rate and maternal axillary temperature after contact and the heart rate of the newborns at the end of the contact.
- ItemAcesso aberto (Open Access)Prevalência de distúrbios gastrointestinais funcionais em lactentes nascidos prematuros(Universidade Federal de São Paulo (UNIFESP), 2019-12-02) Gondim, Marcela Montenegro Braga Barroso [UNIFESP]; Morais, Mauro Batista de [UNIFESP]; Goulart, Ana Lucia [UNIFESP]; http://lattes.cnpq.br/5519219079407797; http://lattes.cnpq.br/5056114729141952; Universidade Federal de São Paulo (UNIFESP)Objective: To compare the prevalence of functional gastrointestinal disorders in preterm infants with those of term infants using the Rome IV criteria. Additionally, to evaluate whether invasive procedures during the neonatal period are associated with a higher chance of developing functional gastrointestinal disorders in preterm infants. Methods: Controlled cross-sectional study nested in a retrospective cohort of preterm infants who were compared with term infants for functional gastrointestinal disorders. In the preterm group, infants born with a gestational age <37 weeks were included in the study, and in the term group, infants born with a gestational age > 37 weeks and with a birth weight above 2500 grams were included. A face-to-face medical consultation was performed by a single pediatric gastroenterologist for information on the gestational and neonatal period and information on clinical digestive manifestations. Rome IV criteria were used for diagnosing functional gastrointestinal disorders.Results: We studied 197 infants (<24 months), 99 preterm infants and 98 term infants. Infant regurgitation was more prevalent in term infants (35.1% and 15.6%, p <0.001). The prevalence of other functional gastrointestinal disorders in preterm infants was not different, according to statistical analysis, compared to term infants, respectively: infant colic (10.7% and 4.3%; p= 0.360), functional constipation (17.2% and 9.2%; p= 0.098), functional diarrhea (4.6% and 0.0%; p= 0.274) and infant dyschezia (9.3% and 7.5%; p= 0.735). No relationship was found between invasive procedures performed in the neonatal period and higher risk for developing functional gastrointestinal disorders in preterm infants. Conclusion: In the studied population, preterm infants had no higher prevalence of functional gastrointestinal disorders. No relation was found in preterm infants with invasive diagnostic and therapeutic procedures and the development of gastrointestinal manifestations.
- ItemSomente MetadadadosRelação da ingestão dietética com a composição corporal e adipocinas de lactentes prematuros e nascidos a termo(Universidade Federal de São Paulo (UNIFESP), 2021) Vivi, Anna Caroline Pereira [UNIFESP]; Souza, Fabiola Isabel Suano De [UNIFESP]; Universidade Federal de São PauloObjective: To describe and compared the food consumption, nutritional status and leptin, adiponectin, IGF-1 e CPR (C-protein reactive) serum levels of preterm and full-term infants aged between 9 and 24 months. In addition, evaluate the relation between food consumption, nutritional status and leptin, adiponectin, IGF-1 e CPR levels in both groups. Methods: Cross-sectional study involving preterm infants (n 43), between 9 and 24 months of chronological age, under follow-up at the Follow-up Clinic at the São Bernardo do Campo Municipal University Hospital, which were compared a group of health infants, with same age, full-term and appropriate for gestational age, being followed-up in a basic health unit in the same city (n 47). Were evaluated maternal, gestational, neonatal, and feeding introduction history; food consumption, through dietary recall; nutritional status (weight, length, head circumference, skinfold); laboratory analysis (leptin, adiponectin, IGF-1, CPR). Results: In preterm group, 43 infants were evaluated, 24, (55,8%) of whom male gender and the mean corrected age, gestational age and birth weight were 14,2±6,4 months, 29,9±2,3 months e 1245±381,5 grams, respectively. Of these 11 (25.5%) and 13 (30.2%) were born with extremely low weight and small for gestational age, respectively. At the time of assessment, preterm infants compared to the full term group, showed lower values of anthropometric indicators for height/age z score (HAZ: -1,27±1,4 vs 0,25±1,40; p < 0,001), body mass index (BMIZ: -0,40±1,1 vs 0,33±1,2; p = 0,003), head circumference (HCZ: -0,19±1,5 vs 0,76±1,2; p = 0,002), and body composition z score for tricipital skinfold (TSFZ: -0,19±1,5 vs 0,76±1,2; p = 0,001) and subscapular skinfold (SSFZ: -0,98±1,7 vs 0,12±1,4; p = 0,001). There was no statistically significant difference between the groups, preterm and full term, in the levels of leptin, adiponectin and CPR. ZBMI values were associated with leptin levels (0,098; IC 95% 0,022 a 0,175; p = 0,013); the consumption of ultra-processed foods in complementary feeding with those of PCR (0,007; IC 95% 0,002 a 0,017; p = 0,016), after adjusting for sex, group and age. The correlation between ultra-processed food intake and CRP levels was more intense in the preterm group. Conclusion: The infants in the preterm group had levels of leptin, adiponectin, IGF-1 and PCR similar to that of infants born at full term. CRP serum levels correlated with the energy percentage of consumption of ultra-processed foods in the preterm group.
