The peak time period for the average beef producer to experience the majority of calf losses has consistently been from the time of birth through the first seven days of life. Weakness is a principal clinical sign of diseases or conditions responsible for mortality including birth trauma, prematurity or dysmaturity, congenital malformations, metabolic defects, intrauterine infection, anoxia or hypoxia, hypothermia, starvation, extremes in birth weight, and post-natal infection. This article discusses anoxia/hypoxia and septicemia in greater detail because of their involvement as a common cause of weakness in the newborn calf.

The medical records of 74 neonates dependent on parenteral nutrition for at least 21 days after emergency abdominal surgery (performed between 1988 and 1992) were reviewed respectively. The role of enteral starvation, prematurity, composition and duration of parenteral nutrition, and sepsis in the evolution of parenteral nutrition-related cholestasis was evaluated by multiple regression analysis. The most important factors for cholestasis were low gestational age (median, 34 weeks), early exposure to parenteral nutrition, and sepsis. Episodes of sepsis were associated with a 30% increase in the bilirubin level. Enteral starvation and composition and the duration of parenteral nutrition solutions did not correlate significantly with the development of cholestasis. Prevention of sepsis should be the priority in minimising cholestasis in postsurgical neonates who are dependent on parenteral nutrition.

Prematurity, maternal smoking, and low birth weight each result in neuroendocrine dysfunction and increased perinatal morbidity and mortality. Leptin, an adipocyte-secreted protein, has provided the first physiological link to the regulatory system controlling starvation-induced neuroendocrine changes in rodents. This study investigated whether leptin concentrations were detectable in cord blood of newborns, and assessed the effect of birth weight, prematurity, and maternal smoking on cord blood leptin concentrations. Fifty consecutively enrolled full-term and 12 preterm newborns born to mothers who smoked during pregnancy were compared to 50 full-term and 12 preterm newborns born to parents who were nonsmokers. RIA for leptin was performed using cord blood samples collected immediately after birth. Leptin concentrations were detectable in newborns and correlated positively with obesity (full-term, r = 0.30, P < 0.01; preterm, r = 0.47, P < 0.05). Maternal smoking during pregnancy was associated with decreased leptin concentrations in the cord blood of both full-term and preterm newborns. This effect was independent of obesity (full-term newborns: 5.25 +/- 2.48 vs. 4.21 +/- 2.71 ng/ml, P = 0.01) and was more pronounced in premature newborns (5.67 +/- 3.6 vs. 2.46 +/- 2.03, P = 0.02), and its magnitude in full-term newborns was directly related to the reported number of cigarettes the mothers of the full-term newborns smoked per day (r = -0.438, P < 0.001). Thus, low birth weight and maternal smoking are both associated with decreased leptin concentrations, and these effects are more pronounced in premature newborns. Future studies will be needed to determine whether administration of leptin might reverse the neuroendocrine dysfunction caused by maternal smoking.

The purpose of this paper is to review clinical studies on hypophosphatemia in pediatric intensive care unit patients with a view to verifying prevalence and risk factors associated with this disorder. We searched the computerized bibliographic databases Medline, Embase, Cochrane Library, and LILACS to identify eligible studies. Search terms included critically ill, pediatric intensive care, trauma, sepsis, infectious diseases, malnutrition, inflammatory response, surgery, starvation, respiratory failure, diuretic, steroid, antiacid therapy, mechanical ventilation. The search period covered those clinical trials published from January 1990 to January 2004. Studies concerning endocrinological disorders, genetic syndromes, rickets, renal diseases, anorexia nervosa, alcohol abuse, and prematurity were not included in this review. Out of 27 studies retrieved, only 8 involved pediatric patients, and most of these were case reports. One clinical trial and one retrospective study were identified. The prevalence of hypophosphatemia exceeded 50%. The commonly associated factors in most patients with hypophosphatemia were refeeding syndrome, malnutrition, sepsis, trauma, and diuretic and steroid therapy. Given the high prevalence, clinical manifestations, and multiple risk factors, the early identification of this disorder in critically ill children is crucial for adequate replacement therapy and also to avoid complications.
