Byline: James L. Ritchie, Charles Maynard, Nathan R. Every, Michael K. Chapko Abstract: Background Randomized trials of coronary stents versus conventional balloon angioplasty have demonstrated improved short- and long-term outcomes for selected patients receiving stents. The purpose of this study was to compare outcomes in patients receiving stents with those undergoing conventional balloon angioplasty in everyday clinical practice. Methods and Results This study uses information from the Medicare Provider Analysis and Review files for fiscal years 1994 and 1996, the first year the coronary stent code was used. For patients 65 years of age and older, 165,657 cases in 1994 and 201,869 in 1996, including 74,836 cases with stent placement, were identified. Outcomes included hospital deaths, use of same- admission coronary artery bypass surgery, and either or both. Analyses were performed separately for those with and those without a principal diagnosis of acute myocardial infarction. Hospital mortality rates were similar in both years, but the use of same-admission coronary artery bypass surgery was lower in 1996. In that year, for both patients with and those without acute myocardial infarction, hospital death and the use of same-admission coronary artery bypass surgery were lower in the stent group. Additionally, results in the stent group were generally better at high-volume (>200 cases per year) institutions, as was the case for the prestent, 1994 results. Conclusions This study documents improved short-term outcomes in older patients who undergo coronary stent placement. Stenting did not eliminate the finding of improved outcomes at high-volume centers. (Am Heart J 1999;138:437-40.)

During the 1990s, Aotearoa/New Zealand has experienced an alarming increase in youth suicide in the Maori and non-Maori populations. Among 23 Organization for Economic Cooperation and Development countries surveyed by the World Health Organization's (1995) World Health Statistics Annual, New Zealand ranks first for fatal suicidal behavior, in males 15-24 years of age, and third for fatal suicidal behavior in females. A United Nations Children's Fund (UNICEF, 1996) survey of 32 countries places New Zealand males as third highest for fatal suicidal behavior, and females as eighth highest in the age group 15-24 years. New Zealand has recently undergone a number of social and economic changes that have created dramatic social and cultural shifts. Given the rapidity of these changes, the shock on such a small country has been difficult to absorb. These shifts have placed tremendous pressures on families and service support systems, such as health and mental health services, to develop programs that are relevant and acceptable for a bicultural society. This article focuses on these changes and the effect they have had on cultural narratives of gender and suicidal behavior, the different cultural etiologies that underlie these statistics, and recommendations for intervention and prevention program development.

Objective: Current practice guidelines discourage use of lithium during breast-feeding, despite limited data. This study aimed to quantify lithium exposure in nursing infants. Method: In 10 mother-infant pairs, the authors obtained assays of lithium in maternal serum, breast milk, and infant serum and indices of infant renal and thyroid function. Results: Maternal serum, breast milk, and infant serum daily trough concentrations of lithium averaged 0.76, 0.35, and 0.16 meq/liter, respectively, each lithium level lower than the preceding level by approximately one-half. No serious adverse events were observed, and elevations of thyroid-stimulating hormone, blood urea nitrogen, and creatinine were few, minor, and transient. Conclusions: Serum lithium levels in nursing infants were low and well tolerated. No significant adverse clinical or behavioral effects in the infants were noted. These findings encourage reassessment of recommendations against lithium during breastfeeding and underscore the importance of close clinical monitoring of nursing infants.

Objective: Lithium has been used during pregnancy for more than four decades, but quantification of fetal lithium exposure and clinical correlations of such exposure are limited. The study objectives were to 1) quantify the rate of lithium placental passage, 2) assess any association between plasma concentration of lithium at delivery and adverse perinatal events, and 3) determine whether lithium concentrations can be reduced by briefly suspending therapy proximate to delivery. Method: Maternal blood and umbilical cord blood were obtained at delivery for assay of lithium concentrations, and obstetrical outcome data were collected prospectively for 10 participants. These data were combined with results from MEDLINE and PsycINFO searches that identified 32 cases in which maternal lithium was administered throughout delivery. Statistical analysis of the pooled data was conducted. Results: The ratio of lithium concentrations in umbilical cord blood to maternal blood (mean=1.05, SD=0.13) was uniform across a wide range of maternal concentrations (0.2-2.6 meq/liter). Significantly lower Apgar scores, longer hospital stays, and higher rates of CNS and neuromuscular complications were observed in infants with higher lithium concentrations (>0.64 meq/liter) at delivery. Withholding lithium therapy for 24-48 hours before delivery resulted in a 0.28 meq/liter reduction in maternal lithium concentration. Conclusions: Lithium completely equilibrates across the placenta. Higher lithium concentrations at delivery are associated with more perinatal complications, and lithium concentrations can be reduced by brief suspension of therapy proximate to delivery. Treatment guidelines are proposed to improve neonatal well-being when lithium use is indicated in late pregnancy.

A study on cortisol responses among alcoholic Asians with varied ALDH2 genotypes revealed that the subjects had higher cortisol levels after consuming alcohols than subjects with other patterns of genotypes. Asians who possess ALDH2*2 alleles and flush after consuming alcohol experience serious reactions to alcohol when compared to the non-flushing Asians with ALDH2*1/2*1 genotype. Subjects who are homozygous for ALDH2*2 possess exceptionally high cortisol levels within 90, 120 and 150 minutes after consuming alcohol.

Objective: The purpose of this study was to determine the extent of infant medication exposure through breast-feeding during maternal treatment with paroxetine. Method: Breast milk and paired maternal and infant sera were collected after 10 days of maternal treatment with paroxetine at a stable daily dose (10-50 mg/day). All samples were analyzed by means of high-performance liquid chromatography with ultraviolet detection and a limit of detection of 2 ng/ml. Results: Breast milk paroxetine concentrations were highly variable (2-101 ng/ml) and were present in all breast milk samples (N=108). A significant gradient effect was observed, with greater paroxetine concentrations found in later portions of breast milk (hind milk) than in early portions (fore milk). No clear time course of paroxetine excretion into breast milk was demonstrated, although maternal paroxetine daily dose reliably predicted both trough and peak breast milk concentrations over a 24-hour period. In 16 mother and infant serum pairs, no detectable concentrations of paroxetine were found in the serum of the nursing infants. Conclusions: This study extends previous data by demonstrating the presence of paroxetine in the breast milk of nursing women treated with this medication. The low concentrations of paroxetine in infant serum and lack of any observable adverse effects after maternal use of this medication while breast-feeding parallels the available data on other selective serotonin reuptake inhibitors.

Thrombosis, the formation of a blood clot in a blood vessel, can be diagnosed by angioscopy, a microscopic method for examining the blood vessel, and by angiography, a blood vessel imaging technique using X-rays. Thrombosis can be treated by thrombolytic drugs such as streptokinase, or by thrombectomy, surgical removal of the clot. The effectiveness of these diagnostic methods and of thrombolytic therapy was examined in an experimental animal model. The femoral arteries in the legs of 14 dogs were crushed with forceps. Angiography revealed that the femoral arteries were normal in six dogs, had minimal damage in three, and showed narrowing or stenosis in five. Angioscopy revealed a layer of blood clots along the blood vessel wall and abnormalities of the inner layer of the artery in all cases, and showed that six of the 14 dogs had partial obstruction or occlusion of the femoral artery. Thrombosis was then induced in the femoral arteries, and both methods of angiography and angioscopy confirmed that the femoral artery was occluded. After thrombectomy, most arteries appeared normal by angiography, but none were considered normal by angioscopy. Streptokinase given after the thrombectomy improved femoral artery narrowing in one of seven cases. The results show that in the treatment and diagnosis of blood vessel thrombosis, angioscopy is a more sensitive in detecting blood clots. In addition, streptokinase did not appear to provide additional improvement in thrombosis after thrombectomy. (Consumer Summary produced by Reliance Medical Information, Inc.)

Cardiomyopathy -- Causes of ,Alcoholics -- Health aspects ,Alcoholism -- Complications ,Health - Abstract
Preclinical alcoholic cardiomyopathy, myocardial damage in the absence of overt congestive heart failure in chronic alcoholics, is well characterized at necropsy, but attempts to identify such a clinical entity before death have produced conflicting results. dying subjects only at rest, the inclusion of older alcoholics and limitations of noninvasive techniques may explain some of the disagreement. To determine if preclinical alcoholic cardiomyopathy could be identified independent of the aforementioned limitations, 2S asymptomatic chronic alcoholics aged S days per week for >S years, underwent radionuclide ventriculography for measurements of systolic and diastolic function at rest, peak supine exercise and during recovery, and echocardiography for assessment of chamber size, wall thickness and left ventricular mass. Red blood cell levels of selenium and thiamine were measured to determine whether abnormalities were present in these 2 potential mediators of alcoholic cardiomyopathy. For comparison, an age-matched group of healthy control subjects was also studied. For alcoholics and control subjects at rest, mean ejection fraction (67 +/- 7% vs 71 +/- 6%) and diastolic peak filling rate (3.4 +/- 0.6 vs 3.3 +/- 0.6 end-diastolc volumes per second [EDV/s]) were similar. At peak exercise, the mean ejection fraction 83 +/- 6 vs 82 4- 10), change in ejection fraction (14 /- 10 vs 14 7) and peak fining rate (8.9 +/- 2.0 vs 9.S +/- 1.9 EDV/s) were also similar, but election fraction failed to increase appropriately in 3 alcoholics (120/o), suggesting possible stress-induced myocardial dysfunction. Left ventricular chamber size, fractional shortening, wall thickness and ventricular mass by echocardiography were similar in the alcoholic and control groups, as were red blood cell levels of selenium and thiamine. Repeat studies aftor 4 weeks of abstinence from alcohol showed persistence of the exemise-induced abnormal response in 2 of the 3 alcoholics. These data suggest that the occurrence of preclinical cardiomyopathy in young, asymptomatic chronic alcoholics is rare and may require exercise stress testing to be detected. (Am J Cardiol 1991;67:183-187), Chronic alcoholism can result in heart disease and the appearance of clinical symptoms of congestive heart failure (weakness, breathlessness, abdominal discomfort, and pooling of blood in the extremities). This has been attributed to both a direct toxic effect of alcohol on the heart and the detrimental effect that chronic alcohol abuse has on nutritional status. The effects of alcoholism on the heart have been well documented at autopsy, but attempts to characterize the effects of excessive alcohol consumption on the heart before death have yielded conflicting results. To determine the effects of alcoholism on cardiovascular function in younger, relatively healthy alcoholics, 25 men under the age of 40 (average age 34 years) who had consumed one pint of whiskey or one six-pack of beer daily for at least five years were assessed. An age-matched group of nonalcoholic subjects served as a control group. On virtually all cardiovascular parameters measured (resting and exercise mean ejection fraction, diastolic peak filling rate, end-diastolic volumes per second, left ventricular size, wall thickness and mass, and red blood cell selenium and thiamine levels), there were no differences between alcoholics and control subjects. In three alcoholic subjects, exercise failed to induce an appropriate increase in ejection fraction (the percentage of blood ejected from the ventricle during maximal contraction of the heart), suggesting a possible dysfunction in these subjects. After four weeks of abstinence from alcohol, this deficit was still present in two of the three subjects. Hence, the occurrence of alcohol-induced cardiomyopathy in young alcoholics is quite rare, and may require exercise testing to be detected.

This study comprised a registry and an emergency department treatment trial using recombinant tissue plasminogen activator. During 1 year, 1,028 patients with documented acute myocardial infarction (AMI) were evaluated for eligibility for thrombolytic therapy. Of these, 221 patients (22%) were eligible for thrombolytic therapy under currently accepted criteria, 175 (79%) of them were correctly identified by emergency department physicians for thrombolytic therapy, and 160 were enrolled in the trial. Only 3 patients (2%) enrolled by emergency department physicians did not subsequently evolve documented AMI. In all, 807 patients (78%) were ineligible for thrombolytic therapy: 335 (33%) because of [is greater than or equal to]1 contraindications, 364 (36%) because of nondiagnostic electrocardiograms on presentation, and 105 (10%) because of age [is greater than]75 years, or [is greater than]6 hours of chest pain at presentation, or both. Mortality in treated patients at 14 days was 5.6%, and survival at 1 year was 92%. The mean time from hospital arrival to thrombolytic treatment was 55 [+ or -] 27 minutes. Initial management of AMI with recombinant tissue plasminogen activator in the emergency department provided rapid and safe treatment comparable to that reported in trials that started treatment in the coronary care unit. The proportions of eligible patients could be increased from 1 in 5 to 1 in 3, if patients currently excluded only because of age [is greater than]75 years or because of [is greater than]6 hours of chest pain were offered treatment. (Am J Cardiol 1990;66:1298-1303), In acute myocardial infarction (AMI, or heart attack), the blood supply to the heart is impaired by the occlusion of one or more of the coronary arteries, usually by a blood clot. Myocardial infarction results in damage to the heart muscle and may cause death. A recognized treatment for AMI is the administration of thrombolytic agents, such as tissue plasminogen activator (TPA), which dissolve the thrombi, or clots, occluding the coronary arteries. To evaluate the practicality, benefits, and safety of emergency room physicians administering TPA to patients diagnosed as having AMI, 1,028 cases were reviewed. The patients had been admitted to hospitals in the Seattle-Tacoma metropolitan area with diagnoses of presumptive AMI. A total of 807 patients were ineligible for TPA treatment for various reasons, including having had more than one AMI incident, symptoms for more than six hours, age over 75 years, high blood pressure, and recent injury. Of the 221 eligible patients, 7 refused TPA treatment, 46 were not treated because they were incorrectly evaluated in the emergency room as being ineligible, and 168 were treated. The average time to initiate TPA treatment was 55 minutes after hospital admission. At 14 days following AMI, 5.6 percent of the TPA-treated patients had died; at one-year follow-up, the survival rate was 92 percent. If the age and time-from-onset criteria for eligibility were relaxed so that patients over 75 years of age and those with AMI symptoms of more than six hours duration could be treated, the percentage of eligible patients would rise from 20 percent to over 30 percent. Emergency room administration of TPA appears to be as safe and efficacious as administration begun in the coronary care unit. (Consumer Summary produced by Reliance Medical Information, Inc.)

Hemoglobin (Hb) [A.sub.1c] (Hb [A.sub.1c]) is currently the most widely used index of average glycemia and is directly proportional to the mean concentration of glucose in the blood and the [...], Context.--It is recommended that hemoglobin (Hb) [A.sub.1c] (Hb [A.sub.1c]) not be used to assess average glycemia in patients who have altered red blood cell life span. Objective.--To investigate the frequency of reporting an Hb [A.sub.1c] value for Hb variant samples that do not include Hb A. Design.--Hb [A.sub.1c] samples (n = 500) were procured and screened for Hb variants that may affect Hb [A.sub.1c] interpretation (Hb SS, Hb SC, and Hb S-[beta]-thalassemia). Five of each of these samples were tested by ion-exchange high-performance liquid chromatography, immunoturbidimetric assay, second-generation immunoturbidimetric assay, and affinity chromatography. Results.--Eleven (2.2%) homozygous Hb SS, 6 (1.2%) Hb SC, and 5 (1.0%) Hb S-[beta]-thalassemia samples were identified out of the 500 samples tested. Three of 4 instruments investigated in this study are known to not be plagued by analytic interference from these Hb variants but disturbingly reported Hb [A.sub.1c] values in the absence of Hb A. Conclusions.--The improved analytic specificity of Hb [A.sub.1c] platforms has by and large eliminated interferences from the most common heterozygous Hb variants. A consequence, however, is the potential for unintended reporting of Hb [A.sub.1c] results in the presence of homozygous and compound heterozygous Hb variants that lack Hb A and the inability to distinguish those samples not recommended to be used for patient care. The ability to identify samples harboring Hb variants that preclude the utility of Hb [A.sub.1c] may be beneficial in high prevalence populations.

Objective: The authors' goal was to determine the concentration of antidepressants in amniotic fluid during maternal treatment of depression. Method: Women treated with antidepressants undergoing amniocentesis for obstetrical reasons were enrolled. Antidepressant concentrations in amniotic fluid and maternal serum were determined with high-performance liquid chromatography. Results: Amniotic fluid was obtained from 27 women, and the amniotic fluid's antidepressant concentrations were highly variable. For the parent compounds, the amniotic fluid concentrations of selective serotonin uptake inhibitors averaged 11.6% (SD = 9.9%) of maternal serum concentrations (N = 22). Amniotic fluid to maternal serum ratios were higher for venlafaxine: 172% (SD = 91%) (N = 3). Of interest, the amniotic fluid to maternal serum ratios for the metabolites (N = 19) did not demonstrate a consistent pattern compared to the parent compound ratios. In 10 subjects, the amniotic fluid to maternal serum ratio for the metabolites was higher than the parent compound and lower in the remaining nine subjects. Conclusions: The pattern of antidepressant concentrations in amniotic fluid is similar to recent data for placental passage. Although the significance of amniotic fluid exposure remains to be determined, these results demonstrate that maternally administered antidepressants are accessible to the fetus in a manner not previously appreciated.

Laboratory results provide objective data about patient health across the continuum of patient care. (1) In addition, laboratory results enable health care providers to assess early disease risk, opt for [...], Context.--Laboratory medicine is an integral component of patient care. Approximately 60% to 70% of medical decisions are based on laboratory results. Physicians in specialties that order the tests are teaching medical students laboratory medicine and test use with minimal input from laboratory scientists who implement and maintain the quality control for those tests. Objective.--To develop, implement, and evaluate a 1.5-day medical student clinical laboratory experience for fourth-year medical students in their last month of training. Design.--The experience was devised and directed by laboratory scientists and included a panel discussion, laboratory tours, case studies that focused on the goals and objectives recently published by the Academy of Clinical Laboratory Physicians and Scientists, and medical-student presentations highlighting salient points of the experience. The same knowledge quiz was administered at the beginning and end of the experience and 84 students took both quizzes. Results.--A score of 7 or more was obtained by 16 students (19%) on the initial quiz, whereas 34 (40%) obtained the same score on the final quiz; the improvement was found to be statistically significant (P = .002; t = 3.215), particularly in 3 out of the 10 questions administered. Conclusions.--Although the assessment can only measure a small amount of knowledge recently acquired, the improvement observed by fourth-year medical students devoting a short period to learning laboratory medicine principles was encouraging. This medical student clinical laboratory experience format allowed teaching of a select group of laboratory medicine principles in 1.5 days to an entire medical school class.

Effect of hypothyroidism on pathways for iodothyronine and tryptophan uptake into rat adipocytes. Am J Physiol Endocrinol Metab 280: E254-E259, 2001.--Adipocytes are an important target tissue for thyroid hormone action, but little is known of the mechanisms of thyroid hormone entry into the cells. The present results show a strong interaction between transport of iodothyronines [L-thyroxine ([T.sub.4]), L-triiodothyronine ([T.sub.3]), reverse [T.sub.3] (r[T.sub.3])], aromatic amino acids, and the System L amino acid transport inhibitor 2-amino[2,2,1]heptane-2-carboxylic acid (BCH) in white adipocytes. System L appears to be a major pathway of iodothyronine and large neutral amino acid entry into these cells in the euthyroid state. We also demonstrate expression of the CD98hc peptide subunit of the System L transporter in adipocyte cell membranes. Experimental hypothyroidism (28-day propylthiouracil treatment) has no significant effect on System L-like transport of the amino acid tryptophan in adipocytes. In contrast, uptake of [T.sub.3] and especially [T.sub.4] is substantially reduced in adipocytes from hypothyroid rats, partly due to reduction of the BCH-sensitive transport component. Transport of iodothyronines and amino acids in adipocytes therefore becomes decoupled in the hypothyroid state, as occurs similarly in liver cells. This may be due to downregulation or dissociation of iodothyronine receptors from the System L transporter complex. Regulation of iodothyronine turnover in fat cells by this type of mechanism could contribute significantly to modulation of [T.sub.4]-[T.sub.3]/r[T.sub.3] metabolism in the hypothyroid state. adipose tissue; amino acid; thyroid hormone; membrane transport
