A 27-year-old male patient fasted under supervision for 382 days and has subsequently maintained his normal weight. Blood glucose concentrations around 30 mg/100 ml were recorded consistently during the last 8 months, although the patient was ambulant and attending as an out-patient. Responses to glucose and tolbutamide tolerance tests remained normal. The hyperglycaemic response to glucagon wa...

The relationship of vitamin D3 with the duration of mechanical ventilation and mortality is still unknown. Therefore, this study aimed to determine the effect of using high-dose vitamin D on the duration of mechanical ventilation among the patients admitted to the intensive care unit. The current double-blinded clinical trial was performed on 44 mechanically ventilated, adult patients. Us...

An 84-year-old man with severe (GOLDIV) chronic obstructive pulmonary disease (COPD) and a history of pulmonary thromboembolism andwarfarin medicationwas admitted for elective endoscopic retrograde cholangiopancreatography (ERCP) for choledocholithiasis. He had stopped warfarin medication a week before (international normalized ratio [INR] 1.14), and was kept on low-molecular-weight heparin. ER...

BACKGROUND Early tracheostomy may decrease the duration of mechanical ventilation, sedation exposure, and intensive care stay, possibly resulting in improved clinical outcomes, but the evidence is conflicting. METHODS Systematic review and meta-analysis of randomized trials in patients allocated to tracheostomy within 10 days of start of mechanical ventilation was compared with placement of t...

daily discharge data of 12 hydrometric recording stations in atrak river basin were manipulated to calculate low flows for 7-day duration for studying hydrological drought using regional analysis method. using regression models, the low flows for 7-days duration of 10-year return period were calculated and regional low flows were estimated for 20 stations. daily data in each station used to sim...
