Hemoglobin Hematocrit Values Research Articles

The efficiency and safety of intravenous tranexamic acid administration in open reduction and internal fixation of pelvic and acetabular fractures.

This study aimed to investigate the efficiency and safety of tranexamic acid use in open reduction and internal fixation of pelvis and acetabulum fractures. 73 consecutive patients were included. 1000mg TXA was administered intravenously to all patients before surgery. The patients were evaluated on the basis of preoperative, postoperative first and third day hemoglobin-hematocrit values, amount of drainage collected, total blood loss, transfusion rates and complications. Mean operative time was 120.1min. Average decrease in hematocrit levels between preoperative and postoperative first day was 2.1g/dL. Average collected blood from the drain was 177mL. Mean total blood loss was 1137mL. Transfusion rate of the patients was 21%. Mean transfused units was 0.9 units. Three patients died within 3 weeks after the operation due to myocardial infarction, acute kidney failure and pneumonia. There were no cases of symptomatic venous or pulmonary thromboembolism during the 90days of follow-up. Use of TXA in pelvic and acetabular fractures was found to be effective in reducing total blood loss, hemoglobin drop and transfusion rates without increasing venous and pulmonary thromboembolism in our series.

Do Syrian refugees have increased risk for worser pregnancy outcomes? Results of a tertiary center in İstanbul.

Objective:To compare obstetric and perinatal outcomes of Syrian refugee pregnants and Turkish counterparts who gave birth at a tertiary center in İstanbul.Materials and Methods:A retrospective study including the birth records of 704 Syrian refugees and 744 Turkish pregnant women between January 2016 and May 2017 were analyzed. Demographic data, obstetric and neonatal outcomes were compared. The primary aims of this study were to evaluate the pregnancy outcomes and cesarean rates between the groups. The secondary outcomes were the use of antenatal vitamin supplementation, hemoglobin-hematocrit values, and maternal complications.Results:Our results showed that the use of folic acid and iron supplementation rates during pregnancy were similar between the groups (folic acid supplementation 8.1% vs 6.5%, p=0.264; iron supplementation 20.7% vs 19.6%, p=0.125; respectively for Turkish women and Syrian refugees). Cesarean rates were significantly higher for Turkish patients than in Syrian refugees (42.7% vs 32.7%; p<0.05). Gestational age at delivery was significantly higher among Turkish women when compared with Syrian refugees (37.7±2.3 vs 36.4±2.3 weeks, p<0.05), but there was no significant difference regarding the birtweights’ of the newborns (3134 g vs 3066 g for Turkish women and Syrian refugees, respectively, p=0.105). Although obstetric complications were seen more often in Syrian refugees, it did not reach statistical difference (9.7% vs 8.1%, respectively, p=0.285).Conclusion:Syrian refugees use antenatal vitamin supplementations at similar rates to Turkish citizens and obstetric and perinatal outcomes are similar between the groups.

Nutritional status of white college students in Virginia

The nutritional status of the fifty men, fifty-three women, and forty-seven women taking oral contraceptives--all white--between the ages of seventeen and twenty-two years--as reflected by height-weight measurements, hemoglobin-hematocrit values, and dietary records, was similar or slightly better than reported by other investigators. Low hemoglobin values were observed in 2 to 4 per cent of these students, and low hematocrits, in 8 to 17 per cent. Similar hemoglobin and hematocrit values were observed in all women, regardless of whether they were taking oral contraceptives. Exercise patterns; use of vitamin-mineral supplements, "pot," alcoholic beverages, special diets; whether subjects ate alone; where subjects ate; snacking; number of meals consumed daily; whether subjects had ever been diagnosed as being anemic; and what subjects thought of their food habits did not affect hemoglobin or hematocrit. Iron intakes of many of the women students were below the allowance.

The effects of feeding an elemental chemical diet to mature rats: Toxicologic and pathologic studies

An 8-week study was conducted in mature Sprague-Dawley rats to determine the effect of feeding a liquid elemental chemical diet as the sole source of nutrition. Periodic studies showed that blood and urine were normal except for a slight decrease in urine specific gravity, blood urea nitrogen, and hemoglobin-hematocrit values in some of the animals. Prolonged prothrombin times and bleeding, observed in some animals, were ascribed to a questionable deficiency of vitamin K. Histopathologic examinations of the tissues showed no abnormalities except for the indication, in some animals, that fatty metamorphic changes had occurred in the liver. Apparently these changes resulted from a lipotropic factor deficiency that was reversed by the addition of choline to the diet. In all other respects the diet appeared to be well tolerated.

Hemoglobin and hematocrit values of adolescents. Nutritional survey of low income groups.

Using height-weight and hemoglobin-hematocrit values to estimate nutritional status, 268 consecutive adolescent patients from low-income families were evaluated at the adolescent clinic of the University of Alabama Medical Center. Only four of the 123 boys and six of the 145 had hemoglobin values less than 11 Gm./100 ml. of blood, and in only one patient was the anemia due solely to iron deficiency. White boys and girls had higher hemoglobin and. hematocrit values than Negro boys and girls. The mean hemoglobin values from this group of low-income adolescents were similar to those from surveys of Minnesota farm boys and girls and caf adolescents attending a high-income private school in New York City. A number of other observations of practical clinical value are discussed in the text.
