Data Correlations Between Gender, Cytomegalovirus Infection And T Cells, Nk Cells, And Soluble Immune Mediators In Elderly Humans, Ahmad Al-Attar, Steven R. Presnell, Charlotte A. Peterson, D. Travis Thomas, Charles T. Lutz

Pathology and Laboratory Medicine Faculty Publications

We describe a cohort of 50 elderly subjects, age at least 70 years. We present gender-specific findings in T lymphocyte markers and soluble immune mediators. We show the correlation between cytomegalovirus infection status with CD56dim NK cell responses to a variety of stimuli and with CD56bright/CD56dim NK cell ratio. We also present the correlation of retinol binding protein (RBP)−4 plasma levels with NK cell responses and we explore the relationship between gender and adiponectin, 25(OH)D (vitamin D), and RBP4 in affecting CD56dim NK cell responses. These data are discussed in Al-Attar et al. (2016)

Lack Of An Association Or An Inverse Association Between Low-Density-Lipoprotein Cholesterol And Mortality In The Elderly: A Systematic Review, Uffe Ravnskov, Rokura Hama, Tomohito Hamazaki, Paul J. Rosch, Tore Schersten, Ralf Sundberg

NYMC Faculty Publications

OBJECTIVE: It is well known that total cholesterol becomes less of a risk factor or not at all for all-cause and cardiovascular (CV) mortality with increasing age, but as little is known as to whether low-density lipoprotein cholesterol (LDL-C), one component of total cholesterol, is associated with mortality in the elderly, we decided to investigate this issue.

SETTING, PARTICIPANTS AND OUTCOME MEASURES: We sought PubMed for cohort studies, where LDL-C had been investigated as a risk factor for all-cause and/or CV mortality in individuals ≥60 years from the general population.

RESULTS: We identified 19 cohort studies including 30 cohorts with …

Journal Articles: Infectious Diseases

BACKGROUND: Health care associated transmission of Mycobacterium tuberculosis (TB) is well described. A previous survey of infection control (IC) practices at clinical research sites in low and middle income countries (LMIC) funded by the National Institute of Allergy and Infectious Diseases (NIAID) conducting HIV research identified issues with respiratory IC practices. A guideline for TB IC based on international recommendations was developed and promulgated. This paper reports on adherence to the guideline at sites conducting or planning to conduct TB studies with the intention of supporting improvement.

METHODS: A survey was developed that assessed IC activities in three domains: facility …

Department of Paediatrics and Child Health

Background: Globally, pre-eclampsia and eclampsia are major contributors to maternal and perinatal mortality; of which the vast majority of deaths occur in less developed countries. In addition, a disproportionate number of morbidities and mortalities occur due to delayed access to health services. The Community Level Interventions for Pre-eclampsia (CLIP) Trial aims to task-shift to community health workers the identification and emergency management of pre-eclampsia and eclampsia to improve access and timely care. Literature revealed paucity of published feasibility assessments prior to initiating large-scale community-based interventions. Arguably, well-conducted feasibility studies can provide valuable information about the potential success of clinical trials …

NYMC Faculty Publications

A surveillance study in 1996 identified the USA100 clone (ST5/SCCmecII)-also known as the "New York/Japan" clone-as the most prevalent MRSA causing infections in 12 New York City hospitals. Here we update the epidemiology of MRSA in seven of the same hospitals eighteen years later in 2013/14. Most of the current MRSA isolates (78 of 121) belonged to the MRSA clone USA300 (CC8/SCCmecIV) but the USA100 clone-dominant in the 1996 survey-still remained the second most frequent MRSA (25 of the 121 isolates) causing 32% of blood stream infections. The USA300 clone was most common in skin and soft tissue infections (SSTIs) …

Kimmel Cancer Center Papers, Presentations, and Grand Rounds

Atovaquone is an FDA-approved anti-malarial drug, which first became clinically available in the year 2000. Currently, its main usage is for the treatment of pneumocystis pneumonia (PCP) and/or toxoplasmosis in immune-compromised patients. Atovaquone is a hydroxy-1,4-naphthoquinone analogue of ubiquinone, also known as Co-enzyme Q10 (CoQ10). It is a well-tolerated drug that does not cause myelo-suppression. Mechanistically, it is thought to act as a potent and selective OXPHOS inhibitor, by targeting the CoQ10-dependence of mitochondrial complex III. Here, we show for the first time that atovaquone also has anti-cancer activity, directed against Cancer Stem-like Cells (CSCs). More specifically, we demonstrate that …

The Pseudomonas Aeruginosa Efflux Pump Mexghi-Opmd Transports A Natural Phenazine That Controls Gene Expression And Biofilm Development, Hassan Sakhtah, Leslie Koyama, Yihan Zhang, Diana K. Morales, Blanche Fields, Alexa Price-Whelan, Deborah Hogan

Dartmouth Scholarship

Redox-cycling compounds, including endogenously produced phenazine antibiotics, induce expression of the efflux pump MexGHI-OpmD in the opportunistic pathogen Pseudomonas aeruginosa Previous studies of P. aeruginosa virulence, physiology, and biofilm development have focused on the blue phenazine pyocyanin and the yellow phenazine-1-carboxylic acid (PCA). In P. aeruginosa phenazine biosynthesis, conversion of PCA to pyocyanin is presumed to proceed through the intermediate 5-methylphenazine-1-carboxylate (5-Me-PCA), a reactive compound that has eluded detection in most laboratory samples. Here, we apply electrochemical methods to directly detect 5-Me-PCA and find that it is transported by MexGHI-OpmD in P. aeruginosa strain PA14 planktonic and biofilm cells. We …

Anesthesiology and Critical Care Medicine Faculty Publications

Background

The diagnosis of acute appendicitis can be surprisingly difficult without computed tomography, which carries significant radiation exposure. Circulating blood cells may carry informative changes in their RNA expression profile that would signal internal infection or inflammation of the appendix.

Methods

Genome-wide expression profiling was applied to whole blood RNA of acute appendicitis patients versus patients with other abdominal disorders, in order to identify biomarkers of appendicitis. From a large cohort of emergency patients, a discovery set of patients with surgically confirmed appendicitis, or abdominal pain from other causes, was identified. RNA from whole blood was profiled by microarrays, and …

Factors That Influence Advance Directives Completion Amongst Terminally Ill Patients At Akuhn, Stephen Omondi Otieno May 2016

Factors That Influence Advance Directives Completion Amongst Terminally Ill Patients At Akuhn, Stephen Omondi Otieno

Master of Medicine in Internal Medicine

Background: An advance directive is a written or verbal document that legally stipulates a person’s health care preference while they are competent to make decisions for themselves, and which is then used to guide decisions on life-sustaining treatment in the event that they become incapacitated. Advance directives can take one of four forms: a living will, a limitation of care document, a do-not-resuscitate order, and an appointment of a surrogate by durable power of attorney. The completion rate of advance directives varies from region to region, and it is influenced by different patient, caregiver, legal, institutional, cultural, and religious factors. …

Background: As the prevalence of cardiovascular diseases in Sub-Saharan Africa rises, coronary artery disease, with its acute presentations, is being increasingly recognized in Kenyans and treated at tertiary level hospitals. It is just over a decade since the introduction and wide availability of modern cardiology services, including interventional cardiology in Kenya. Following an acute coronary syndrome (ACS), patients remain at high risk of death and other adverse events such as heart failure, recurrent myocardial infarction, stroke, and bleeding. Local and regional data on long-term outcomes following ACS are lacking. These data are important to clinicians for prognostication and to health …


The Association Between Asymptomatic And Mild Neurocognitive Impairment And Adherence To Antiretroviral Therapy Amongst People Living With Hiv, Violet Maloba Awori May 2016

The Association Between Asymptomatic And Mild Neurocognitive Impairment And Adherence To Antiretroviral Therapy Amongst People Living With Hiv, Violet Maloba Awori

Master of Medicine in Internal Medicine

Background: HIV disease is associated with neurocognitive impairment which is one of the neurological complications of the viral infection. The spectrum of HIV Associated neurocognitive impairment has significantly changed since the advent of ART. The inclusion of the asymptomatic but cognitively impaired population of patients has changed the dynamics of this population, and requires further research to identify the impact it has on the progression of the disease as well as on any other aspects. Poor adherence to ART is one of the main causes of treatment failure and studies done previously point towards the milder forms of Neurocognitive Impairment …

Kimmel Cancer Center Papers, Presentations, and Grand Rounds

Cancer is now viewed as a stem cell disease. There is still no consensus on the metabolic characteristics of cancer stem cells, with several studies indicating that they are mainly glycolytic and others pointing instead to mitochondrial metabolism as their principal source of energy. Cancer stem cells also seem to adapt their metabolism to microenvironmental changes by conveniently shifting energy production from one pathway to another, or by acquiring intermediate metabolic phenotypes. Determining the role of cancer stem cell metabolism in carcinogenesis has become a major focus in cancer research, and substantial efforts are conducted towards discovering clinical targets.

There is little information in the literature about its treatment or susceptibilities. We describe the case of a 67-year-old male with paraplegia who developed urosepsis due to S. fonticola. Blood and urine cultures obtained prior to the initiation of antimicrobials both grew S. fonticola. The patient completed a 15-day course of antimicrobials and had an uneventful recovery.We reviewed 17 other patients with clinical cultures positive for S. fonticola. Of these, 11 isolates were from the genitourinary system, most often as part …


Hiv Vaccines: Progress, Limitations And A Crispr/Cas9 Vaccine, Omar A. Garcia Martinez May 2016

Hiv Vaccines: Progress, Limitations And A Crispr/Cas9 Vaccine, Omar A. Garcia Martinez

Biology: Student Scholarship & Creative Works

ABSTRACT: The HIV-1 pandemic continues to thrive due to ineffective HIV-1 vaccines. Historically, the world’s most infectious diseases, such as polio and smallpox, have been eradicated or have come close to eradication due to the advent of effective vaccines. Highly active antiretroviral therapy is able to delay the onset of AIDS but can neither rid the body of HIV-1 proviral DNA nor prevent further transmission. A prophylactic vaccine that prevents the various mechanisms HIV-1 has to evade and attack our immune system is needed to end the HIV-1 pandemic. Recent advances in engineered nuclease systems, like the CRISPR/Cas9 system, have …

Sonographic Estimation Of The Prevalence Of Hepatic Steatosis In Hiv Monoinfected Patients At Aga Khan University Nairobi., Bernadette Wambui Muthee

Master of Medicine in Imaging and Diagnostic Radiology

Introduction: Human immunodeficiency virus disease (HIV) is a worldwide health problem. It is estimated that 38.6 million people are infected with HIV globally. It has remained endemic in the African continent for close to 20 years and is a long term developmental challenge in Africa which bears 69 % of the HIV/AIDS global burden. The introduction of highly active antiretroviral therapy (HAART) has caused dramatic improvement in prognosis of HIV disease. Consequently, this has resulted in substantial reduction in Acquired Immune Deficiency Syndrome (AIDS) related morbidity and mortality. In contrast, this has been accompanied by an upsurge in liver- related …

The Mysteries Of Your Blood, Alexandra J. Mauer May 2016

The Mysteries Of Your Blood, Alexandra J. Mauer

BU Well

Did you know that your blood type can be useful for determining disease susceptibility and even creating a diet that works best for your personal metabolism? The Mysteries of your Blood is an article that delves into the science behind the ABO blood types and explains why your body can handle certain foods, stress, and illness differently than someone with a different blood type. It proposes a new, perplexing way to determine how to avoid certain health problems while at the same time offering suggestions of what to eat or, rather, what to avoid eating.
