Lower plasma melatonin levels in non-hypoxic premature newborns associated with neonatal pain.

Unlabelled: We analyzed plasma melatonin levels in different groups of preterm newborns without hypoxia and their relationship with several perinatal variables like gestational age or neonatal pain. Prospective cohort study of preterm newborns (PTNB) without perinatal hypoxia, Apgar > 6 at 5 min, and oxygen needs on the third day of life. We compared melatonin levels at day 3 of life in different groups of non-hypoxic preterm infants (Student's t-tests, Mann-Whitney U, and chi) and analyzed the relationship of melatonin with GA, birth weight, neonatal pain (Premature Infant Pain Profile (PIPP) scale), caffeine treatment, parenteral nutrition, or the development of free radical diseases (correlation study, linear regression) and factors associated with moderate/intense pain and free radical diseases (logistic regression analysis).

Needs Assessment in Parents of Children Affected by Cancer: A Qualitative Perspective.

Background: Childhood cancer is a "stressful experience" for parents in their role as caregivers. The aim of this study is to analyze the needs of a group of parents who have children diagnosed with cancer. The assessment looks at all areas of their daily life using a qualitative content analysis approach.

When Your Child Has Cancer: A Path-Analysis Model to Show the Relationships between Flourishing and Health in Parents of Children with Cancer.

Background: Childhood cancer is a disease with a psychosocial impact on parents who experience health problems and distress. Their reactions depend on the relationship of multiple factors. The objective of this paper is to evaluate the interrelationships between flourishing and the variables linked to the health and wellbeing of parents of children with cancer.

Blood Lead Level in a Paediatric Population of South-Eastern Spain and Associated Risk Factors.

Objective: To determine blood lead levels (BLL) in a healthy paediatric population and to analyse related sociodemographic, dietary and haematological factors.

Methods: A cross-sectional study was made of 1427 healthy subjects aged 1-16 years from the city of Almería (south-eastern Spain). BLL, iron parameters and erythropoietin were determined, and sociodemographic and dietary data obtained.

Relationship between Obesity and Iron Deficiency in Healthy Adolescents.

The relationship between overweight/obesity (excess of weight [EW]) and iron deficiency (ID) is not well defined. To analyze the relationship between EW and ID in healthy adolescents, assessing the contribution of new diagnostic measures of iron status and erythropoietic activity. A cross-sectional study was made of 405 healthy adolescents, 12-16 years of age.

Prevalence of iron deficiency and related factors in Spanish adolescents.

Iron deficiency anaemia continues to be the world's most important cause of years lived with disability in children and adolescents. Assessment of iron deficiency traditionally depended on laboratory parameters that may be modified by inflammation states, including obesity, which is nowadays a current condition in adolescent population of high-income countries. The present study ascertains the prevalence of iron deficiency and its related factors in adolescents, using the serum transferrin receptor and the reticulocyte haemoglobin content, in order to avoid this confusing effect of classical parameters.

Monitoring the Frequency and Duration of Hypoglycemia in Preterm Infants and Identifying Associated Factors.

Hypoglycemia is common in very low birth weight neonates and may have adverse effects. Sixty preterm infants were monitored using continuous glucose monitoring (CGMS) and capillary techniques during the first week of life. Hypoglycemia was defined as glucose ≤47 mg/dL (≤2.

Insulinaemia and insulin resistance in Caucasian general paediatric population aged 2 to 10 years: Associated risk factors.

Background: The aim of this study is to determine values of insulinaemia, homeostasis model assessment (HOMA) index and quantitative insulin sensitivity check index (QUICKI) among a population of prepubertal Caucasian children, to analyse factors associated with insulin resistance (IR), and to study its association with cardiovascular risk factors.

Materials And Methods: Population-based study conducted on a randomly selected sample of prepubescent Caucasian subjects aged 2.00 to 9.

Prevalence of overweight and obesity in children and adolescents aged 2-16 years.

Objectives: To estimate the prevalence of obesity and overweight in children and adolescents in our city and to investigate the associated factors.

Subjects And Methods: A cross-sectional study of 1317 children and adolescents aged 2-16 years. Multistage probability sampling was used to select three groups of subjects: 411 aged 12 to 16 years, 504 aged 6 to 12 years, and 402 aged 2 to 6 years.

Iodine intake and prevalence of thyroid autoimmunity and autoimmune thyroiditis in children and adolescents aged between 1 and 16 years.

Objectives: To determine the status of iodine nutrition in children and adolescents in Almería, Spain. To calculate prevalence of thyroid autoimmunity (TA) and autoimmune thyroiditis (AT) in pediatric ages and to research into associated factors.

Methods: Cross-sectional epidemiological study.

The usefulness of serum transferrin receptor for discriminating iron deficiency without anemia in children.

We determined serum transferrin receptor (sTfR), serum erythropoietin and hematologic and biochemical iron parameters in 251 healthy children. The levels of sTfR were significantly higher in children with storage iron deficiency but had a poor sensivity for recognizing iron deficiency without anemia. When ferritin values cannot accurately demonstrate the iron deficiency in children, the sTfR/ferritin ratio or sTfR-log ferritin is recommended to discriminate iron deficiency in the absence of anemia.
