Idade materna como fator de risco: estudo com primigestas na faixa etária igual ou superior a 28 anos

Trata-se de estudo transversal, cujo objetivo foi analisar a idade materna como fator de risco ou não, através da verificação de intercorrências na gestação, parto e puerpério de primigestas com idade igual ou superior a 28 anos e das condições de nascimento e alta de seus recém-nascidos, comparando-as com o grupo de primigestas na faixa etária de 20 a 27 anos. Foi realizado em Botucatu/S.P., no período de janeiro de 1990 a junho de 1995. A análise estatística, discutida ao nível de 5% de significância, foi realizada através da prova de Mann-Whitney, teste de Goodman e avaliação do risco relativo e risco relativo corrigido, através da técnica de Mantel-Haenszel. Concluiu-se que a idade materna igual ou superior a 28 anos não constituiu fator de risco gestacional, puerperal e intra-parto mas, por outro lado, foi fator de risco, mesmo após controlado o tipo de parto, para as seguintes intercorrências perinatais: taquipnéia transitória do recém-nascido, cianose generalizada ao nascer e infecção neonatal.

Relação do peso de recém-nascidos e placentas. Estudo em recém-nascidos de termo, pré-termo e pós-termo, de pesos adequado, baixo e grande para a idade gestacional

Birth weight and placental weight of 566 newborns were determined. The newborns were classified by birth weight and gestational age in seven groups: term, preterm and postterm newborns with weight appropriate for gestational age; term and postterm newborns small for gestational age; term and preterm newborns large for gestational age. The differences in the mean placental weight in the preterm, term and postterm newborns with weight appropriate for gestational age were not significant. After 34 weeks of gestation there was little increase in placental weight. The mean placental weight of newborns large for gestational age was significantly different from that of term newborns appropriate for gestational age. In the term and postterm newborns small for gestational age the mean placental weight was significantly different from term and postterm newborns appropriate for gestational age. These findings suggest that newborns with an appropriate intrauterine growth have little increase in placental weight in the gestational period. Gestational age is not an important factor in determining placental weight in this period. Nutrition is important for placental growth-retarded infants have small placentas and large-for-date infants have large placental weight.

Estudo do peso e da idade gestacional de recem-nascidos e dos fatores que interferem no desenvolvimento fetal: nivel socio-economico, fatores maternos, fetais e placentarios

The present study was undertaken to determine the importance of socioeconomic factors (family income), urban or rural family location, parity, maternal age, the presence of maternal and fetal pathologies as well as placental abnormalities on the weight and gestational age of 566 newborns. The highest incidence of newborns with low birth weight for gestational age was significantly more frequent in urban populations when the mothers were from low socio-economic levels. In mothers from low socioeconomic levels infants with low birth weight for gestational age were seen in greater proportion among primaparas and had a tendency to be higher in mothers aged less than 20 years; prematurity was highest in mothers ≥ 30 years old and significantly higher from the 8th gestation on. Maternal and fetal pathologies emphasized these characteristics and placental pathologies were not correlated with the distribution of weight and length of gestation. In mothers of high socioeconomic levels age and parity were not correlated with weight and gestational age of the newborns.

Alterações anatomopatológicas placentárias. Relação com o peso e idade gestacional de recém-nascido

The authors studied gross and histological abnormalities of placentae from 566 newborns, grouped according to birth and gestational age. The relation of hemorragic abnormalities, infections of membranes and placental tissue, chronic infections, calcifications, hydropic degeneration of villi, chorangioma, cysts, vascular lesions (endarteritis) with newborn weight, length of gestation and intrauterine growth retardation were determined. We concluded that lesions due to disturbances of placental blood flow were significantly more frequent in placentae from term newborns small for gestational age; villi hydropic degenerations were more frequent in placentae of pre-term newborns appropriate for gestational age. Chronic infections had a tendency to be greater in placentae from infants with diminished intrauterine growth. Term newborns small for gestational age had greater proportions of placental abnormalities than the other groups.

Insulinoterapia, controle glicêmico materno e prognóstico perinatal - Diferença entre o diabetes gestacional e o clínico

PURPOSE: to evaluate the insulin therapy protocol and its maternal and perinatal outcome in patients with clinical or gestational diabetes in a high risk reference service. METHODS: descriptive and prospective study including 103 pregnant women with gestational or clinical diabetes treated with insulin and attended by the reference service from October 2003 to December 2005. Gemellarity, miscarriages, unfinished prenatal care and deliveries not attended by the service were excluded. The gestational age at the beginning of the treatment, dosage, doses/day, increment of insulin (UI/kg), glycemic index (GI) and perinatal outcomes were compared. ANOVA, Fisher's exact test and Goodman's test considering p<0.05 were used. RESULTS: multiparity (92 versus 67.9%), pre-gestational body mass index (BMI) >25 kg/m 2 (88 versus 58.5%), weight gain (WG) <8 kg (36 versus 17%) and a high increment of insulin characterized the gestational diabetes. For the patients with clinical diabetes, despite the highest GI (120 mg/dL (39.2 versus 24%)) at the end of the gestational period, insulin therapy started earlier (47.2 versus 4%), lasted longer (56.6 versus 6%) and higher doses of insulin (92 versus 43 UI/day) were administered up to three times a day (54.7 versus 16%). Macrosomia was higher among newborns from the cohort of patients with gestational diabetes (16 versus 3.8%), being the only significant neonatal outcome. There were no neonatal deaths, except for one fetal death in the cohort of patients with clinical diabetes. There were no differences in the other neonatal complications in both cohorts, and most of the newborns were discharged from hospital up to seven days after delivery (46% versus 55.8%). CONCLUSIONS: the analysis of these two cohorts has shown differences in the insulin therapy protocol in quantity (UI/day), dosage (UI/kg weight) and number of doses/day, higher for the clinical diabetes cohort, and in the increment of insulin, higher for the gestational diabetes cohort. Indirectly, the quality of maternal glycemic control and the satisfactory perinatal outcome have proven that the treatment protocol was adequate and did not depend on the type of diabetes.

Farmacología en la tercera edad: Medicamentos de uso continuo y peligros de la interacción medicamentosa

Introduction: It was observed a considerable growth of elderly people. They are who use more medicines. The physiological changes associated with the age advancing can make pharmacokinetic and pharmacodynamic alterations. The cognitive decline, physical limitations and associate chronic pathology affect the medications appropriately use ability. Aims: Based in a literature review, appoint the main pharmacological groups prescribed to the elderly and the drug-drug interaction risks. Conclusion: The most of elderly use continually at least 3 medicines, the most prescribed are to cardiovascular and psychic diseases treatment.
