The relationships among monocyte subsets,miRNAs and inflammatory cytokines in patients with acute myocardial infarction

Background

Acute myocardial infarction (AMI) causes irreversible myocardial damage and release of inflammatory mediators, including cytokines, chemokines and miRNAs. We aimed to investigate changes in the levels of cytokines (IL-6, TNF-α and IL-10), miRNAs profiles (miR-146 and miR-155) and distribution of different monocyte subsets (CD14++CD16-, CD14++CD16+, CD14+CD16++) in the acute and post-healing phases of AMI.

The eye care profile and outcomes of multi-handicapped adults residing in Wayne County, Michigan group homes.

BACKGROUND: Patients with multi-handicaps present clinical challenges and are underserved. Central nervous system dysfunction and ocular disorders with this population are prevalent and well-documented. However, vision care outcomes data are limited and specific visual function recommendations to caregivers are rarely cited. METHODS: The charts of 110 multiply handicapped adults residing in 22 group homes in Wayne County. Michigan were retrospectively studied to identify ocular profiles and predictors of visual function. RESULTS: Sixty-five percent of the subjects were male and 80% were ages 26 to 55 years. There was no expressive language in 41%, and 37% were non-ambulatory. The median visual impairment level was moderate in both eyes (based on WHO). Significant associations between visual impairment level and subpopulations (such as seizure disorder, mental retardation without specific etiology, cerebral palsy, and Down syndrome) were identified. Successful spectacle wear statistically increased with higher refractive errors. Associations between cataract, nystagmus, and strabismus with particular subpopulations were significant (all P values < 0.0182). CONCLUSIONS: Clinicians who evaluate patients with multi-handicaps have few known predictors of treatment success. This study indicates that useful predictors of visual function can be made from refractive error, systemic conditions, and ocular diagnoses. No significant relationship was found with cognitive level and either vision impairment or spectacle use. The authors attribute successful implementation of recommendations to communication with group home caregivers.     

Smoking and coffee intake following alcohol withdrawal in alcoholic inpatients

The aim of this study was to assess alcoholic inpatients' smoking and coffee intake variation following withdrawal. Only moderate smokers (less than 30 cigarettes/day) showed a significant increase of cigarette consumption after alcohol withdrawal. However, their urinary cotinine level did not vary, suggesting a behavioral, and not biological, compensation through smoking following alcohol withdrawal. Heavy smokers (30 cigarettes/day or more) showed no significant clinical or biological variation of smoking behavior. Coffee consumption increased after alcohol withdrawal in all patients, irrespective of smoking habits.     

Spinal epidural abscess: a ten-year perspective

A retrospective study of spinal epidural abscess spanning 10 years and encompassing 40 patients was done. Epidemiology, clinical features, laboratory findings, radiographic imaging, therapy, and outcome were examined and compared with previous series. An increasing incidence of the disease (up to 1.96 patients per 10,000 admissions per year) and an older, more debilitated population (67% having factors predisposing them to infection) were discovered. Over half of the population was studied with magnetic resonance imaging, which was found to be equally as sensitive (91%) as myelography with computed tomography (92%). Magnetic resonance imaging offers the advantages of being noninvasive and able to delineate other entities, which makes it the imaging modality of choice. Preoperative paralysis and neurological deterioration from normal were identified as poor prognostic features. Of 7 patients with preoperative paralysis, 5 died, and the rest failed to recover neurological function. Eleven patients with initially normal neurological exams deteriorated in the hospital before surgical intervention. Eight of these patients were being treated with appropriate antibiotics; 2 became paralyzed despite more than 3 weeks of antibiotic therapy. Only 3 of these 11 patients recovered fully. Immediate surgical decompression combined with antibiotics remains the treatment of choice.     

Validation in the sheep of an ultrasound velocity dilution technique for haemodialysis graft flow

BACKGROUND: A simple, rapid, inexpensive method for measuring the flow in a patient's vascular access would permit routine monitoring during haemodialysis, and hence provide information of access graft deterioration sufficiently early to increase the success of minimally invasive remedial procedures. This paper reports the validation of such a method in animals. METHODS: A PTFE graft was implanted in sheep between the carotid artery and the jugular vein. While the sheep was under general anaesthesia and on an haemodialysis circuit, ultrasound velocity in its blood was perturbed by the injection of a 5-10 ml bolus of isotonic NaCl. The pump tubing flow was measured by a transit-time blood flow meter. This flow was combined with the areas of perturbation generated by the injection before and after mixing in the access flow to estimate graft flow. The calculated graft flow was compared to flow measured directly by a transit-time probe on the same carotid artery. RESULTS: Over a 10-fold range, 120-1260 ml/min, graft flow measured by ultrasound velocity dilution agreed well with graft flow measured directly with a scatter of 76 ml/min about the regression line. CONCLUSION: Ultrasound velocity dilution provides a method for measuring flow in the graft accurate enough for clinical evaluation of patients on dialysis.      

Safety of Intravenous Immunoglobulin Preparations: A Prospective Multicenter Study to Exclude the Risk of Non-A, Non-B Hepatitis

The risk of non-A, non-B hepatitis transmission by an intravenous immunoglobulin (IVIG) preparation was assessed in a prospective multicenter trial in 68 patients with primary immunodeficiency disorders (40 children or adolescents and 28 adults). During the 4-week prestudy evaluation period the clinical examinations and liver function tests including alanine aminotransferase, aspartate aminotransferase, gamma-glutamyl transpeptidase, alkaline phosphatase, and bilirubin were normal in all patients. The treatment consisted of three infusions of 200 mg IVIG (pH 4; pepsin procedure) per kilogram body weight at 2-week intervals. During the observation period of 24 weeks following the first infusion of the study IVIG, the patients were monitored at regular time intervals. No clinical and laboratory signs of hepatitis or liver dysfunction were noticed. All patients completed the study. In 5 patients, one isolated alanine aminotransferase value and in another patient one gamma-glutamyl transpeptidase value were moderately elevated, but always below 2.5 times the upper limit of the reference range. Similar isolated and transient elevations were observed for aspartate aminotransferase and alkaline phosphatase. It was concluded that the IVIG preparation did not transmit non-A, non-B hepatitis or other viral liver diseases.     

Incidence of protein calorie malnutrition in the nursing home population

That nutritional parameters change with age is a well-known phenomenon. Physical activity, lean body mass, and metabolic rate all decline with increasing age. There has been little work regarding the nutritional assessment of geriatric nursing home patients to determine their nutritional status and to focus attention on their nutritional needs. The purpose of this study was to assess the nutritional status of the residents of two urban nursing homes. The nutritional status of 227 nursing home residents (mean age 72.2 years) was evaluated using biochemical and anthropometric measurements. Midarm muscle circumference, triceps skinfold thickness, weight, height, serum albumin, serum pre-albumin, serum retinol binding protein, and a complete blood count with differential were obtained. The evaluation of this data indicated that there was a 52% incidence of malnutrition. This can be broken down to: 24% hypoalbuminemic malnutrition, 19% Kwashiokor-Marasmus mix, and 9% Marasmus. Twenty-eight percent of all patients were anergic, and 76% of the patients were anemic. In conclusion, there appears to be far more documentable malnutrition than anticipated or previously reported in this population.     

Folate status during pregnancy: relationship with alcohol consumption, other maternal risk factors and pregnancy outcome.

This study was designed to identify the factors affecting folate status in pregnant women and to explore the relationship between folate status and alcohol consumption during pregnancy. For this purpose, 347 French women were recruited during 1985-1986 on their first visit to the antenatal clinic at Roubaix Hospital (northern France). Alcohol consumption was ascertained by a standardized interview. Folate status assessment was available for 246 pregnant women who were not given folate supplementation. Average folate levels during pregnancy were lower among young women and smokers. Serum folate values diminished with the educational level, and red cell folate values increased with high parity. Unexpectedly, high red cell folate values were strongly related with high alcohol consumption after adjustment for the maternal risk factors associated with alcohol consumption and folate status. This was probably because in the Roubaix region where the study was conducted women consume mostly beer, which contains folates. Pregnancy outcome was not related to folate levels; birthweight was negatively associated with alcohol consumption during the first trimester of pregnancy.     

Combination of ABO blood group incompatibility and glucose-6-phosphate dehydrogenase deficiency: effect on hemolysis and neonatal hyperbilirubinemia

The incidence (%) of hyperbilirubinemia (serum bilirubin ≥257 μmol/l) was similar in neonates with a combination of ABO incompatibility and glucose-6-phosphate dehydrogenase (G-6-PD) deficiency (45%), with ABO incompatibility (54%) or G-6-PD deficiency (37%), alone (ns). Carboxyhemoglobin values, corrected for inspired CO, were similarly elevated in all three groups (0.87 ± 0.32%, 0.82 ± 0.29%, 0.76 ± 0.18%, respectively, ns), but correlated with bilirubin only in those with ABO incompatibility alone. ABO-incompatible/G-6-PD-deficient neonates, compared with those with either condition alone, are not at increased risk for hemolysis or hyperbilirubinemia.     

Management of pregnancy and childbirth in England and Wales and in France

This paper reviews national data on obstetric and neonatal practices in England and Wales, and in France between 1970 and 1980. The data have been derived from national statistics and surveys on national samples of births in 1970, 1975 and 1980 in England and Wales, and 1972, 1976 and 1981 in France. The analysis shows that there was no major difference in pregnancy outcome, but wide variations in medical practices, and their trend over time. The main differences were: in England and Wales a higher number of antenatal visits, a higher percentage of inpatient admissions during pregnancy, a higher rate of induction, more episiotomies, a higher rate of resuscitation at birth, and admission to neonatal special care units; in France, a higher rate of caesarean sections before and during labour, some evidence of a more active management of labour, and a longer hospital post-natal stay. These differences in practice reflect differences in objectives and assessment of the effectiveness of care between the two countries: they point out the need for better monitoring and evaluation of obstetric and neonatal practices.
