ISHLT consensus document on lung transplantation in patients with connective tissue disease: Part III: Pharmacology, medical and surgical management of post-transplant extrapulmonary conditions statements

Patients with connective tissues disease (CTD) are often on immunomodulatory agents before lung transplantation (LTx). Till now, there's no consensus on the safety of using these agents perioperative and post-transplant. The International Society for Heart and Lung Transplantation-supported consensus document on LTx in patients with CTD addresses the risk and contraindications of perioperative and post-transplant management of the biologic disease-modifying antirheumatic drugs (bDMARD), kinase inhibitor DMARD, and biologic agents used for LTx candidates with underlying CTD, and the recommendations and management of non-gastrointestinal extrapulmonary manifestations, and esophageal disorders by medical and surgical approaches for CTD transplant recipients.

Higher- or Usual-Volume Feedings in Infants Born Very Preterm: A Randomized Clinical Trial

OBJECTIVE

To determine whether higher-volume feedings improve postnatal growth among infants born very preterm.

STUDY DESIGN

Randomized clinical trial with 1:1 parallel allocation conducted from January 2015 to June 2018 in a single academic medical center in the US. In total, 224 infants with a birth weight 1001-2500 g born at <32 weeks of gestation were randomized to higher-volume (180-200 mL/kg/d) or usual-volume (140-160 mL/kg/d) feedings after establishing full enteral feedings (≥120 mL/kg/d). The primary outcome was growth velocity (g/kg/d) from randomization to study completion at 36 weeks of postmenstrual age or hospital discharge if earlier.

RESULTS

Growth velocity increased among infants in the higher-volume group compared with the usual-volume group (mean [SD], 20.5 [4.5] vs 17.9 [4.5] g/kg/d; P < .001). At study completion, all measurements were higher among infants in the higher-volume group compared with the usual-volume group: weight (2365 [324] g, z score -0.60 [0.73] vs 2200 [308] g, z score -0.94 [0.71]; P < .001); head circumference (31.9 [1.3] cm, z score -0.30 [0.91] vs 31.4 [1.3] cm, z score -0.53 [0.84]; P = .01); length (44.9 [2.1] cm, z score -0.68 [0.88] vs 44.4 [2.0], z score -0.83 [0.84]; P = .04); and mid-arm circumference (8.8 [0.8] cm vs 8.4 [0.8] cm; P = .002). Bronchopulmonary dysplasia, patent ductus arteriosus, necrotizing enterocolitis, or other adverse outcomes did not differ between groups.

CONCLUSIONS

In infants born very preterm weighing 1001-2500 g at birth, higher-volume feedings increased growth velocity, weight, head circumference, length, and mid-arm circumference compared with usual-volume feedings without adverse effects.

Nutrition of neonates with congenital heart disease: existing evidence, conflicts and concerns

Introduction: Congenital heart disease is one of the most of the groups of congenital anomalies with an incidence of about 1 per 100 live births. Almost one-third of these infants require some type of intervention, usually in the first year of life and increasingly often in the neonatal period. Innovative reparative and palliative surgical procedures and advanced medical support in the Neonatal Intensive Care Unit have significantly reduced the mortality related to congenital heart disease. Achieving survival is not the only target of clinicians for these patients. Appropriate growth, development, and improved quality of life are also very important. Growth failure is a very common problem of these children and nutritional support and management are a challenge for health care providers. Early intervention and identification of at-risk patients have the potential to decrease morbidity and mortality related to malnutrition.Aim/methods: The purpose of this article is to analyze the existing evidence and common concerns about perioperative and postdischarge nutritional management of neonates with congenital heart disease based on the special issues or complications that may arise. Furthermore, we reviewed the recent literature about current practices and proposed policies that could prevent malnutrition and improve the outcomes of neonates with congenital heart disease.Results/conclusion: A standardized institutional protocol and clear guidelines referring to feeding initiation, prompt estimation of caloric needs and provision of adequate and appropriate nutrient intake is likely to benefit these patients. Clear definitions for the nutritional approach in the setting of medical complications and close assessment of growth by pediatricians and specialized nutritionists are crucial for the long-term outlook and quality of life of these infants.
