ABSTRACT

Background Acute changes in cerebral function after elective coronary bypass surgery are a difficult clinical problem. We carried out a multicenter study to determine the incidence and predictors of — and the use of resources associated with — perioperative adverse neurologic events, including cerebral injury.

Methods In a prospective study, we evaluated 2108 patients from 24 U.S. institutions for two general categories of neurologic outcome: type I (focal injury, or stupor or coma at discharge) and type II (deterioration in intellectual function, memory deficit, or seizures).

Results Adverse cerebral outcomes occurred in 129 patients (6.1 percent). A total of …

Decreases In Ovarian Cytochrome P450c17 Alpha Activity And Serum Free Testosterone After Reduction Of Insulin Secretion In Polycystic Ovary Syndrome, John E. Nestler , M.D., Daniela J. Jakubowicz , M.D.

Obstetrics and Gynecology Publications

BACKGROUND

Insulin resistance and increased ovarian cytochrome P450c17α activity are both features of the polycystic ovary syndrome. P450c17α, which is involved in androgen biosynthesis, has both 17α-hydroxylase and 17,20-lyase activities. Increased activity of this enzyme results in exaggerated conversion of progesterone to 17α-hydroxyprogesterone in response to stimulation by gonadotropin. We hypothesized that hyperinsulinemia stimulates ovarian P450c17α activity.

METHODS

We measured serum steroid concentrations during fasting and the response of serum 17α-hydroxyprogesterone to leuprolide, a gonadotropin-releasing hormone agonist, and performed oral glucose-tolerance tests before and after oral administration of either metformin (500 mg three times daily) or placebo for four to …

Time Course Of Recruitment, Pit Formation And Apoptosis Of Osteoclast Populations On Dentin In Vitro, Jihyun Kang, Rigoberto Cornejo, Kevin J. Hirokawa, Susan M. Digiorgio, Darlene F. Howard, Susan F. Silverton

Cells and Materials

The resorptive capacity of osteoclasts in vitro has been used as an indicator of bone resorption. However, the kinetics of osteoclast development and senescence is not well understood. It has been noted that mononuclear precursors migrate to calcified substrate and after multi-nucleation become competent bone resorbing cells. Osteoclasts, once finished a wave of resorption, become senescent. In order to determine the survival characteristics of osteoclast populations involved in calcified tissue destruction, we have investigated the time course of the recruitment to dentin and apoptosis of osteoclasts. We have established the linkage between these measurements and the time course of the …

Biofilm Mediated Calculus Formation In The Urinary Tract, Robert J. C. Mclean, David J. Stickler, J. Curtis Nickel

Cells and Materials

Mineralization and subsequent calculus formation is a common complication of biofilm infections. In the urinary tract, these infected calculi often arise from infections by urease-producing bacteria. Ammonia, liberated by bacterial urease activity, increases urine pH, resulting in the precipitation of Ca and Mg as carbonateapatite {Ca₁₀(PO₄,CO₃)₆(OH,CO₃)₂} and struvite (NH₄MgP0₄·6H₂O). These minerals become entrapped in the organic matrix which surrounds the infecting organisms and ultimately grow into mature calculi. When the causative organisms grow on urinary catheters and stents, the resulting mineralization can …

Perturbations Of Periosteel Bone During Healing: Effect Of Non-Weight Bearing, Helen E. Gruber, Mary E. Kirchen, John R. Sweeney, William E. Anderson, G. June Marshall

Cells and Materials

Weight bearing (WB) is an important factor influencing bone remodelling. The present study evaluates the effects of weight bearing and non-weight bearing (S) (achieved by tail suspension and hindlimb elevation) on the healing of a fibular osteotomy in adult male rats. After 9, 18 or 36 days under WB or S conditions, periosteum near the callus formed at the osteotomy site was compared to periosteum of the contralateral fibula (which did not receive an osteotomy) or to periosteum of fibula of control animals which did not receive an osteotomy. Data show that periosteal bone healing is sensitive to alterations in …

Validation Of Energy Dispersive X-Ray Spectrometry As A Method To Standardize Backscattered Electron Images Of Bone, E. G. Vajda, R. D. Bloebaum, J. G. Skedros

Cells and Materials

The use of backscattered electron (BSE) imaging as a tool for the qualitative measurement of mineral content in bone has been well documented. The challenge still remains to develop BSE imaging as a tool for quantitative mineral content analysis in bone. The limiting factor has been the ability to standardize the BSE signal within and between laboratories. Energy dispersive x-ray spectrometry (EDX) has been proposed as a method to standardize the BSE operating environment. The goal of this study is to investigate the relationship between EDX-determined wt.% Ca measurements and BSE graylevels. A comparison with traditional ash content measurements will …

Preventing Perinatal Transmission Of Hiv Costs And Effectiveness Of A Recommended Intervention, Robin D. Gorsky, P G. Farnham, Walter L. Straus, Blake Caldwell, D R. Holtgrave, R. J. Simonds, M F. Rogers, Mary Guinan

School of Public Health Faculty Research

In the United States, nearly all new human immunodeficiency virus (HIV) infections in children are acquired through perinatal (mother-to-infant) transmission. Each year, approximately 7000 infants are born to HIV-infected women in the United States.¹ Without intervention, an estimated 15-30% of these infants would become infected.² In 1994, results of the AIDS Clinical Trial Group (ACTG) Protocol 076 showed that treatment of infected pregnant women and their infants with zidovudine (ZDV) reduced the rate of perinatal HIV transmission from 25% to 8%.^3,4 Following these findings, the Public Health Service (PHS) issued recommendations for ZDV therapy to prevent perinatal …

Analysis Of The Effects Of Overexpression Of Metallothionein-I In Transgenic Mice On The Reproductive Toxicology Of Cadmium., T Dalton, Kai Fu, G C Enders, R D Palmiter, G K Andrews

Journal Articles: Pathology and Microbiology

Exposure to low levels of cadmium reduces fertility. In male mice spermatogenesis is highly sensitive to cadmium, whereas in females the peri-implantation period of pregnancy is sensitive. To examine the potential roles of the cadmium-binding protein, metallothionein (MT), in the reproductive toxicology of cadmium, we examined a transgenic mouse strain that overexpresses metallothionein-I (MT-I). These mice had dramatically increased steady-state levels of MT-I mRNA and MT in the testes and in the female reproductive tract during the peri-implantation period of pregnancy, and this overexpression occurred in a cell-specific and temporally regulated manner similar to that of the endogenous MT-I gene. …

Knowledge, Sources Used And Factors Considered In The Surgical Treatment Decisions Of Women With Breast Cancer, Debra J. Bisel

Masters Theses

The purpose of this replication study was to examine how women with breast cancer reached their decision for surgical treatment (Ward, Heidrich and Wolberg 1989). Twenty-one women who met the surgical criteria, i.e. option for Breast Conserving surgery or Modified Radical Mastectomy, completed four surveys 1 to 7 days post operatively. The women were divided into two groups, 13 who had Breast Conserving surgery and 8 who had Modified Radical Mastectomy. The surveys assessed demographic characteristics of the groups, the level of knowledge regarding breast cancer, factors considered important in reaching the decision for surgery and the sources of information …

American Longevity: Past, Present, And Future, Samuel H. Preston

Center for Policy Research

How long we live, and how long members of our families and social groups live, is extraordinarily important to us. It's not a subject of daily discussion, but it would be if we were threatened with a return to earlier conditions. Unfortunately, the subject of longevity falls between the cracks of academe and has received far less attention than it warrants. We are all aware, at least dimly, that people are living longer than they used to. The numbers are impressive: at the turn of the century, life expectancy at birth in the United States was 48 years; it's now …

Nutritional Problems And Information Needs Of Patients Receiving Chemotherapy And Radiation Therapy, Margaret Joan Robinson

Theses : Honours

Nutritional status is a major factor in determining the successful outcome of treatment for cancer. The combined effect of cancer, and the treatment for cancer, has the potential to severely impair nutritional status. The purpose of this study was to investigate the incidence and severity of treatment-related side-effects which affect nutritional status in cancer patients and to determine the sources and helpfulness of information about nutrition which had been utilised by patients. A descriptive study was used to investigate two groups of patients, one group who was receiving chemotherapy, and the other, radiation therapy. A questionnaire developed by the researcher …

Treatment Practices For Degedege, A Locally Recognized Febrile Illness, And Implications For Strategies To Decrease Mortality From Severe Malaria In Bagamoyo District, Tanzania, A.M. Makemba, P.J. Winch, V.M. Makame, G.L. Mehl, Zul Premji, J.N. Minjas, C.J. Shiff

Pathology, East Africa

Malaria remains one of the chief causes of mortality among young children in sub-Saharan Africa. Verbal autopsies for cases of childhood mortality in Bagamoyo District, Tanzania demonstrated that degedege, a locally defined illness of children characterized by fever and convulsions, is frequently treated by traditional healers. To investigate this further, an ethnographic study was carried out in one village that included in-depth interviews with 14 traditional healers and 3 focus groups with parents. Parents and traditional healers were unanimous in their conviction that degedege requires traditional treatments, at least initially, and that these treatments are effective. While traditional healers do …

Our Hearts Were Once Young And Gay: Health Care Rationing And The Elderly, George P. Smith Ii

Scholarly Articles

Although there exists no rigid guideline delineating society's obligation to provide health care, at a minimum Americans are entitled to an adequate level of care without excessive burdens being placed upon them. Fulfilling this ostensibly simple mandate, however, presents an enormous challenge. The need to allocate limited financial and human resources increasingly clashes with the moral desire to provide health care resources to elder Americans beyond their years of economic productivity. As a result, health care professionals face the difficult task of weighing against society's other priorities the efficiency of distributing limited health care resources to the elderly. This demand …

Perceived Barriers And Perceived Motivators To Receiving Prenatal Care, Christine M. Davis

Masters Theses

The Health Belief Model served as the conceptual framework for this retrospective descriptive study that identified women's perceived barriers and perceived motivators to obtaining prenatal care. A 50 item questionnaire, including both forced-choice and open-ended questions, was administered to 29 women who had delivered a healthy infant within the previous 6 to 8 weeks. The sample was predominantly white (82.2%), {dollar}>{dollar}19 years of age (62.1%), single (62.1%), unemployed (51.7%), and receiving Medicaid insurance (69%). Univariate statistics were calculated for each item. Each item was then compared to the timing of the start of prenatal care. The most important motivators …

The Role Of Social Support Networks In The Independent Functioning Of Elderly Persons, Maree Gabbedy

Theses : Honours

There is conclusive evidence which highlights the importance of physical and mental health in the ability of elderly persons to function within society, and elderly persons who require services to maintain their independence, are assumed to have lower levels of functioning than persons who do not apply for, or require assistance. Individuals, however, are rarely totally independent, as most people are involved in social networks, where the reciprocal exchange of money, emotional support, goods and services are exchanged with friends family and neighbours. This study, examined the role of social support networks in the independent functioning of the elderly, in …

Mandibular Asymmetry In Unilateral Class Ii Malocclusion : A Cephalometric Study, Raed Z. Moussa

Loma Linda University Electronic Theses, Dissertations & Projects

The purpose of this study is to evaluate skeletal and dental asymmetry in unilateral class II malocclusion. A study group of 25 unilateral subdivision patients was compared to 25 class I malocclusion patients serving as the control group. Submento-vertical and frontal radiographs were used for the evaluation. Symmetry was evaluated by comparing measurements between right and left sides for both groups and matching the middle points with the midsagittal axis. Statistical paired and simple t-test were used to evaluate the difference between the two sides for both groups. The measurements showed no significant skeletal and dental asymmetries except for three …

Stimulation Of Alpha 1(I) Procollagen Gene Expression In Nih-3t3 Cells By The Human T Cell Leukemia Virus Type 1 (Htlv-1) Tax Gene., E. Munoz, D. Suri, S. Amini, K. Khalili, Sergio A. Jimenez

Selected Works of Sergio Jiménez, MD, MACR

The mechanisms that regulate the expression of genes encoding extracellular matrix proteins in fibroblasts and other mesenchymal cells have remained elusive. Studies from several laboratories have indicated that Tax, a trans-regulatory protein from the human T cell leukemia virus type I not only augments viral gene expression but also triggers the expression of various cellular genes. Here, we examined the hypothesis that the expression of collagen genes may also be modulated by Tax. NIH-3T3 cells were simultaneously transfected with a Tax expressor plasmid and a chimeric construct containing regulatory sequences (-804 to +42 bp) of the alpha 1(I) procollagen gene …
