Trends In Mortality From Septicaemia And Pneumonia With Economic Development: An Age-Period-Cohort Analysis, Irene O.L. Wong, Benjamin J. Cowling, Gabriel M. Leung, Mary Schooling

Publications and Research

Background
Hong Kong population has experienced drastic changes in its economic development in the 1940s. Taking advantage of Hong Kong’s unique demographic and socioeconomic history, characterized by massive, punctuated migration waves from Southern China, and recent, rapid transition from a pre-industrialized society to the first ethnic Chinese community reaching ‘‘first world’’ status over the last 60 years (i.e., in two or three generations), we examined the longitudinal trends in infection related mortality including septicemia compared to trends in non-bacterial pneumonia to generate hypotheses for further testing in other recently transitioned economies and to provide generalized aetiological insights on how economic …

Lung Cancer Screening For The Poor And Underserved: Should Routine Screening Be Performed?, Vaibhav Verma, Vladimir K. Gotlieb, Joshua Fogel, Alan S. Multz, Geeti Sharma

Publications and Research

Background: Lung cancer is a leading cause of death in United States. A recent study using low dose CT scans for screening long term smokers for lung cancer has, for the first time, demonstrated reduction in mortality, although it is not a standard of care in the community yet.

In April 2012, PHR's Richard Sollom, Deputy Director, and Holly Atkinson, MD, FACP, past President of PHR's Board and volunteer expert, authored a report showing the devastation on Bahrain's health system that have resulted from the Government of Bahrain’s continued assault on doctors, patients, and the healthcare system.

Posttraumatic Stress And Myocardial Infarction Risk Perceptions In Hospitalized Acute Coronary Syndrome Patients, Donald Edmondson, Jonathan A. Shaffer, Ellen-Ge Denton, Daichi Shimbo, Lynn Clemow

Publications and Research

Posttraumatic stress disorder (PTSD) is related to acute coronary syndrome (ACS; i.e., myocardial infarction or unstable angina) recurrence and poor post-ACS adherence to medical advice. Since risk perceptions are a primary motivator of adherence behaviors, we assessed the relationship of probable PTSD to ACS risk perceptions in hospitalized ACS patients (n = 420). Participants completed a brief PTSD screen 3-7 days post-ACS, and rated their 1-year ACS recurrence risk relative to other men or women their age. Most participants exhibited optimistic bias (mean recurrence risk estimate between "average" and "below average"). Further, participants who screened positive for current PTSD (n …

The Association Between Marital Transitions, Body Mass Index, And Weight: A Review Of The Literature, Lauren Dinour, May May Leung, Gina Tripicchio, Sahar Khan, Ming-Chin Yeh

Objective: To examine the association between different marital transitions and changes in body mass index (BMI) and body weight.

Methods: A systematic literature search was conducted for peer-reviewed articles published between January 1990 and December 2011. Longitudinal studies were included if they compared dependent variables, such as BMI or weight, before and after a change in marital status.

Results: Twenty articles were included: 4 articles described only transitions into marriage and/or cohabitation, 2 articles described only transitions out of marriage and/or cohabitation, and 14 articles described both. Overall, transitions into marriage were associated with weight gain, whereas transitions out of …

Cost Effective Malaria Risk Control Using Remote Sensing And Environmental Data, Md Zahidur Rahman, Leonid Roytman, Abdel Hamid Kadik

Publications and Research

Malaria transmission in many part of the world specifically in Bangladesh and southern African countries is unstable and epidemic. An estimate of over a million cases is reported annually. Malaria is heterogeneous, potentially due to variations in ecological settings, socio-economic status, land cover, and agricultural practices. Malaria control only relies on treatment and supply of bed networks. Drug resistance to these diseases is widespread. Vector control is minimal. Malaria control in those countries faces many formidable challenges such as inadequate accessibility to effective treatment, lack of trained manpower, inaccessibility of endemic areas, poverty, lack of education, poor health infrastructure and …

The Manufacture Of Lifestyle: The Role Of Corporations In Unhealthy Living, Nicholas Freudenberg

Publications and Research

Recently, researchers have debated two views on the connection between lifestyle and health. In the first, health-related lifestyles including tobacco and alcohol use, diet, and physical activity are seen as primary influences on health. In the second, social stratification is the dominant influence with lifestyles simply markers of social status. Neither approach leads to interventions that can reverse the world's most serious health problems. This article proposes that corporate practices are a dominant influence on the lifestyles that shape patterns of health and disease. Modifying business practices that promote unhealthy lifestyles is a promising strategy for improving population health. Corporations …

Persistent Disparities In Cholesterol Screening Among Immigrants To The United States, Jim P. Stimpson, Fernando A. Wilson, Rosenda Murillo, Jose A. Pagan

Publications and Research

Background: This study compared differences in cholesterol screening among immigrant populations and US born race/ethnic groups and whether improving access to health care reduced differences in screening.

Methods: Self-reported cholesterol screening for adults was calculated from multivariate logistic regression analysis of the 1988–2008 National Health and Nutrition Examination Surveys (N = 17,118). Immigrant populations were classified by place of birth and length of residency.

Results: After adjusting for individual characteristics and access to health care, the multivariate adjusted probability of cholesterol screening is significantly lower for persons originating from Mexico (70.9%) compared to persons born in the US (80.1%) or …

Polyglutamine Toxicity Is Controlled By Prion Composition And Gene Dosage In Yeast, He Gong, Nina V. Romanova, Kim D. Allen, Pavithra Chandramowlishwaran, Kavita Gokhale, Gary P. Newnam, Piotr Miceczkowski, Michael Y. Sherman, Yury O. Chernoff

Publications and Research

Polyglutamine expansion causes diseases in humans and other mammals. One example is Huntington’s disease. Fragments of human huntingtin protein having an expanded polyglutamine stretch form aggregates and cause cytotoxicity in yeast cells bearing endogenous QN-rich proteins in the aggregated (prion) form. Attachment of the proline(P)-rich region targets polyglutamines to the large perinuclear deposit (aggresome). Aggresome formation ameliorates polyglutamine cytotoxicity in cells containing only the prion form of Rnq1 protein. Here we show that expanded polyglutamines both with (poly-QP) or without (poly-Q) a P-rich stretch remain toxic in the presence of the prion form of translation termination (release) factor Sup35 (eRF3). …

Life-Course Origins Of Social Inequalities In Adult Immune Cell Markers Of Inflammation In Developing Southern Chinese Population: The Guangzhou Biobank Cohort Study, Douglas A. West, Gabriel M. Leung, Chao Q. Jiang, Timothy M. Elwell-Sutton, Wei S. Zhang, Tai H. Lam, Kar K. Cheng, Mary Schooling

Publications and Research

Background
Socioeconomic position (SEP) throughout life is associated with cardiovascular disease, though the mechanisms linking these two are unclear. It is also unclear whether there are critical periods in the life course when exposure to better socioeconomic conditions confers advantages or whether SEP exposures accumulate across the whole life course. Inflammation may be a mechanism linking socioeconomic position (SEP) with cardiovascular disease. In a large sample of older residents of Guangzhou, in southern China, we examined the association of life course SEP with inflammation.

Methods
In baseline data on 9,981 adults (≥ 50 years old) from the Guangzhou Biobank Cohort …

Advances In Ultrafast Time Resolved Fluorescence Physics For Cancer Detection In Optical Biopsy, R. R. Alfano

Publications and Research

We discuss the use of time resolved fluorescence spectroscopy to extract fundamental kinetic information on molecular species in tissues. The temporal profiles reveal the lifetime and amplitudes associated with key active molecules distinguishing the local spectral environment of tissues. The femtosecond laser pulses at 310 nm excite the tissue. The emission profile at 340 nm from tryptophan is non-exponential due to the micro-environment. The slow and fast amplitudes and lifetimes of emission profiles reveal that cancer and normal states can be distinguished. Time resolved optical methods offer a new cancer diagnostic modality for the medical community.

Plasticity Of Corticospinal Neural Control After Locomotor Training In Human Spinal Cord Injury, Maria Knikou

Publications and Research

Spinal lesions substantially impair ambulation, occur generally in young and otherwise healthy individuals, and result in devastating effects on quality of life. Restoration of locomotion after damage to the spinal cord is challenging because axons of the damaged neurons do not regenerate spontaneously. Body-weight-supported treadmill training (BWSTT) is a therapeutic approach in which a person with a spinal cord injury (SCI) steps on a motorized treadmill while some body weight is removed through an upper body harness. BWSTT improves temporal gait parameters, muscle activation patterns, and clinical outcome measures in persons with SCI. These changes are likely the result of …

Culture Ontogeny: Lifespan Development Of Religion And The Ethics Of Spiritual Counselling, Glen Milstein, Amy Manierre

Publications and Research

The counsellor has an ethical obligation to treat the whole person. Humans are cultural beings and the foundation of most cultures is religion. Religion and culture are received from our early relation~ ships and modified through later relationships across the lifespan. The paper introduces the term "culture ontogeny" to emphasize that this is a biological process wherein abstract ideas of culture and religion become material in the developing neurophysiology of each brain. A framework and methods are offered to examine the changing roles of religion in clients' emotional self~ structure, inclusive of those who describe themselves as spiritual, not religious. …

Vitamin D: Implications Of The Institute Of Medicine Report For Clinical Practice, Dorothy Grasso, Margaret A. Rafferty

Publications and Research

In November 2010, the Institute of Medicine (IOM) released Dietary Reference Intakes for Calcium and Vitamin D, a radical departure from previous advice given regarding these two nutrients that have been reported in respected health journals. The 14-member expert committee found clear and convincing evidence to support the association between adequate levels of vitamin D and bone health. The IOM committee did not find enough evidence to support claims that inadequate levels of vitamin D are linked to increased risks for cancer, cardiovascular disease, or diabetes. In this article, the authors discuss the controversy surrounding vitamin D and provide guidance …

The Murine Caecal Microrna Signature Depends On The Presence Of The Endogenous Microbiota, Natasha Singh, Elize A. Shirdel, Levi Waldron, Regan-Heng Zhang, Igor Jurisica, Elena M. Comelli

Publications and Research

The intestinal messenger RNA expression signature is affected by the presence and compo-sition of the endogenous microbiota, with effects on host physiology. The intestine is also characterized by a distinctive micronome. However, it is not known if microbes also impact intestinal gene expression epigenetically. We investigated if the murine caecal microRNA expression signature depends on the presence of the microbiota, and the potential implica-tions of this interaction on intestinal barrier function. Three hundred and thirty four mi-croRNAs were detectable in the caecum of germ-free and conventional male mice and 16 were differentially expressed, with samples from the two groups clustering …

Multiple Sclerosis Is Not A Disease Of The Immune System, Angelique Corthals

Publications and Research

Multiple sclerosis is a complex neurodegenerative disease, thought to arise through autoimmunity against antigens of the central nervous system. The autoimmunity hypothesis fails to explain why genetic and environmental risk factors linked to the disease in one population tend to be unimportant in other populations. Despite great advances in documenting the cell and molecular mechanisms underlying MS pathophysiology, the autoimmunity framework has also been unable to develop a comprehensive explanation of the etiology of the disease. I propose a new framework for understanding MS as a dysfunction of the metabolism of lipids. Specifically, the homeostasis of lipid metabolism collapses during …

Methods: Data are from a randomized controlled trial conducted in 6 prenatal clinics. Women in their 1^st or 2^nd trimester were screened for behavioral risks (smoking, environmental tobacco smoke exposure, depression, and intimate partner violence) and demographic eligibility. 1,044 were eligible, interviewed and followed through their pregnancies. Classification and Regression Trees (CART) methodology was …

Phylogenomics Of Reichenowia Parasitica, An Alphaproteobacterial Endosymbiont Of The Freshwater Leech Placobdella Parasitica, Sebastian Kvist, Apurva Narechania, Alejandro Oceguera-Figueroa, Bella Fuks, Mark E. Siddall

Publications and Research

Although several commensal alphaproteobacteria form close relationships with plant hosts where they aid in (e.g.,) nitrogen fixation and nodulation, only a few inhabit animal hosts. Among these, Reichenowia picta, R. ornata and R. parasitica, are currently the only known mutualistic, alphaproteobacterial endosymbionts to inhabit leeches. These bacteria are harbored in the epithelial cells of the mycetomal structures of their freshwater leech hosts, Placobdella spp., and these structures have no other obvious function than housing bacterial symbionts. However, the function of the bacterial symbionts has remained unclear. Here, we focused both on exploring the genomic makeup of R. parasitica and on …

Solution Structure And Dna-Binding Properties Of The Phosphoesterase Domain Of Dna Ligase D, Aswin Natarajan, Kaushik Dutta, Deniz B. Temel, Pravin A. Nair, Stewart Shuman, Ranajeet Ghose

Publications and Research

The phosphoesterase (PE) domain of the bacterial DNA repair enzyme LigD possesses distinctive manganese-dependent 3'-phosphomonoesterase and 3'-phosphodiesterase activities. PE exemplifies a new family of DNA end-healing enzymes found in all phylogenetic domains. Here, we determined the structure of the PE domain of Pseudomonas aeruginosa LigD (PaePE) using solution NMR methodology. PaePE has a disordered N-terminus and a well-folded core that differs in instructive ways from the crystal structure of a PaePE•Mn(2+)• sulfate complex, especially at the active site that is found to be conformationally dynamic. Chemical shift perturbations in the presence of primertemplate duplexes with 30-deoxynucleotide, …

Prenatal Cocaine Exposure Increases Synaptic Localization Of A Neuronal Rasgef, Grasp-1 Via Hyperphosphorylation Of Ampar Anchoring Protein, Grip, Kalindi Bakshi, Mary Kosciuk, Robert G. Nagele, Eitan Friedman, Hoau-Yan Wang

Publications and Research

Prenatal cocaine exposure causes sustained phosphorylation of the synaptic anchoring protein, glutamate receptor interacting protein (GRIP1/2), preventing synaptic targeting of the GluR2/3-containing alpha-amino-3-hydroxy-5-methyl-4- isoxazolepropionic acid-type glutamate receptors (AMPARs; J. Neurosci. 29: 6308–6319, 2009). Because overexpression of GRIP-associated neuronal rasGEF protein (GRASP-1) specifically reduces the synaptic targeting of AMPARs, we hypothesized that prenatal cocaine exposure enhances GRASP-1 synaptic membrane localization leading to hyper-activation of ras family proteins and heightened actin polymerization. Our results show a markedly increased GRIP1-associated GRASP-1 content with approximately 40% reduction in its rasGEF activity in frontal cortices (FCX) of 21-day-old (P21) prenatal cocaineexposed rats. This cocaine effect …

Thirty-five percent of FSW and 25% of VCT clients had never been HIV tested. Per national guidelines, 33% of newly HIV-diagnosed FSW and 36% of VCT clients were already eligible …

Relationships Between Self-Reported Smoking, Household Environmental Tobacco Smoke Exposure And Depressive Symptoms In A Pregnant Minority Population, Sylvia Tan, Lauren P. Courtney, Ayman El-Mohandes, Susan M. Blake, Marie G. Gantz, Jutta Thornberry, M. Nabil El-Khorazaty, David Perry, Michele Kiely

Publications and Research

This study sought to examine relationships between depressive symptoms and prenatal smoking and/or household environmental tobacco smoke exposure (HHETSE) among urban minority women. We analyzed private, audio computer-assisted self interview data from a clinic-based sample of 929 minority pregnant women in Washington, DC. Depressive symptoms were assessed via the Beck Depression Inventory Fast Screen. HH-ETSE, current smoking, and former smoking were assessed via self-report. Depression levels and demographic characteristics were compared: (1) among nonsmokers, for those reporting HH-ETSE versus no HH-ETSE; and (2) among smokers, for those reporting current smoking (in last 7 days) versus former smokers. Measures associated with …

How Does Socioeconomic Development Affect Copd Mortality? An Age-Period-Cohort Analysis From A Recently Transitioned Population In China, Jing Chen, Mary Schooling, Janice Mary Johnston, Anthony Johnson Hedley, Sarah Morag Mcghee

Publications and Research

Background
Chronic obstructive pulmonary disease (COPD) is a leading cause of death, particularly in developing countries. Little is known about the effects of economic development on COPD mortality, although economic development may potentially have positive and negative influences over the life course on COPD. We took advantage of a unique population whose rapid and recent economic development is marked by changes at clearly delineated and identifiable time points, and where few women smoke, to examine the effect of macro-level events on COPD mortality.

Methods
We used Poisson regression to decompose sex-specific COPD mortality rates in Hong Kong from 1981 to …

Differences Between Trypanosoma Brucei Gambiense Groups 1 And 2 In Their Resistance To Killing By Trypanolytic Factor 1, Paul Capewell, Nicola J. Veitch, C. Michael R. Turner, Jayne Raper, Matthew Berriman, Stephen L. Hajduk, Annette Macleod

Publications and Research

Background: The three sub-species of Trypanosoma brucei are important pathogens of sub-Saharan Africa. T. b. brucei is unable to infect humans due to sensitivity to trypanosome lytic factors (TLF) 1 and 2 found in human serum. T. b. rhodesiense and T. b. gambiense are able to resist lysis by TLF. There are two distinct sub-groups of T. b. gambiense that differ genetically and by human serum resistance phenotypes. Group 1 T. b. gambiense have an invariant phenotype whereas group 2 show variable resistance. Previous data indicated that group 1 T. b. gambiense are resistant to TLF-1 due in-part to reduced …

Effectiveness Of A Combined Home Visiting And Group Intervention For Low Income African American Mothers: The Pride In Parenting Program, Kathy S. Katz, Marian H. Jarrett, Ayman El-Mohandes, Susan Schneider, Doris Mcneely-Johnson, Michele Kiely

Publications and Research

Intervention strategies are needed to improve maternal and infant outcomes in minority populations living in poverty. Home visiting by nurses has improved outcomes for mothers and young children, but use of professional staff makes these programs expensive. Pride in Parenting was a randomized controlled trial of paraprofessional home visitation to provide health and developmental intervention for high-risk African American mothers in Washington, DC. This study proposed to test whether paraprofessional visitors drawn from the community could effectively influence health and mothers; parenting behaviors and attitudes. African American mothers with inadequate prenatal care were recruited at delivery and randomized to intervention …
