To assess the efficacy of noninvasive ventilation (NIV) in patients with persistent weaning failure, we conducted a prospective, randomized, controlled trial in 43 mechanically ventilated patients who had failed a weaning trial for 3 consecutive days. This trial was stopped after a planned interim analysis. Patients were randomly extubated, receiving NIV (n = 21), or remained intubated followin...

a selection program is being implemented to improve meat production in makooei sheep. increasing litter size per ewe is the main objective, but possible repercussions on weight traits of lambs should be considered. the aim of this study was to estimate heritability along with genetic and phenotypic correlations between ewe's reproductive vs. weight traits in makooei ewes. data were comprised of...

BACKGROUND Regional weaning centres provide cost effective care for patients who have undergone prolonged mechanical ventilation. There are few published European data on outcomes in these patients. METHODS Patients admitted for weaning to the Lane Fox Respiratory Unit (LFU) between January 1997 and December 2000 were identified. The proportion weaned from mechanical ventilation, in-hospital ...

Gilt progeny have lighter weaning weights and greater postweaning medication and mortality rates compared with the progeny of older parity sows. Because weaning weight has been positively correlated with postweaning survival, this study aimed to determine whether the provision of supplemental milk preweaning could improve weaning weight and subsequent weights as well as postweaning survival of ...

gastric cancer is the most prevalent cancer among men and the third most prevalent cancer among women in iran. its most important reason for death is its belated diagnosis at the advanced stages of the disease. various factors can be effective on the survival of these patients after surgery, which are the major concern in this study.data from 330 patients with gastric cancer who had undergone s...

introduction: insome cases, assist devices are required to ensure an adequate cardiac output after cardiac surgery. intra-aortic balloon pump (iabp) is the most commonly used cardiac assist device, which provides first-line support for patients with heart failure. the aim of this study was to determine factors affecting the mortality rate of patients receiving iabp. materials & methods:  in thi...

OBJECTIVES The aim of this study was to clarify the outcomes of patients who require post-pneumonectomy mechanical ventilation (PPMV). METHODS The medical records of all 548 patients who underwent pneumonectomy between January 1994 and December 2009 were reviewed. PPMV was defined as mechanical ventilation via an endotracheal tube following thoracotomy (continued PPMV) or reintubated and star...

The objective of this study was to evaluate the effects of weaning age on dry matter intake (DMI), average daily gain (ADG), feed efficiency (FE), feed cost (FC) and benefit index (BI) of Holstein calves reared under organic farming system. Thirty two Holstein calves were divided into two treatments: early weaning (EW) vs. late weaning (LW). Calves in the both groups were provided with whole mi...
