In-Vivo Delivery Of Dna Vaccines Using Metallo-Lipid Nanoparticles, Clarissa Sara Gomez

Open Access Theses & Dissertations

There has been a rapidly growing area of research in the design and synthesis of molecules that self-organize in water to form functional nanosystems and due to the high interest in the area metal ligand complexes were tested as drug delivery systems with a Leishmania vaccine. Herein, we present the design, synthesis and functional activity of Cu(II) and Zn(II) complexes that self-assemble in water to form spherical nanoscale structures that exhibit an affinity to bind DNA and deliver it into eukaryotic cells with a high percent efficiency in-vitro. In order to assess the effectiveness of these nanoparticles to deliver DNA …

The departments within the Faculty of Medicine at UBC play a central role in achieving the goals of the expanded medical school, and the goals of the broader health care system. Four strategies are needed for success: make professionalism the tie that binds the Faculty of Medicine and the health authorities; engage clinical and academic de­partments as key drivers of professionalism; ensure knowledge development and continuous learning are recognized as central to professionalism; challenge government to focus on supporting professionalism.

Obesity, Hypertension, And Mental Health Evaluation In Adolescents: A Comprehensive Approach, Stefan G. Kiessling, Kimberly K. Mcclanahan, Hatim A. Omar

Pediatrics Faculty Publications

The global epidemic of childhood and adolescent obesity in developing and developed countries has become a major public health concern. Given the relation between obesity and hypertension as documented in several landmark studies, it is no surprise that as the prevalence of obesity has increased in the pediatric population, the rates of hypertension have also increased substantially. Hypertension is one of the most important risk factors for cardiovascular diseases and stroke; therefore, evaluation and initiation of appropriate treatment are extremely important in the pediatric population. Evaluation for secondary causes of hypertension, including renovascular, renoparenchymal, and endocrine disease is the approach …

Longitudinal Association Of Sleep-Disordered Breathing And Nondipping Of Nocturnal Blood Pressure In The Wisconsin Sleep Cohort Study, Khin Mae Hla, Terry Young, Laurel Finn, Paul E. Peppard, Mariana Szklo-Coxe, Maryan Stubbs

Community & Environmental Health Faculty Publications

Study objectives: The association of sleep-disordered breathing (SDB) and blunting of normal nocturnal lowering of blood pressure (BP) (nondipping) has only been examined cross-sectionally. The purpose of this study is to investigate whether SDB is prospectively associated with nondipping.

Methods: The longitudinal association between SDB and incident nondipping was examined in a subsample of 328 adults enrolled in the Wisconsin Sleep Cohort Study who completed 2 or more 24-hour ambulatory BP studies over an average of 7.2 years of follow-up. SDB identified by baseline in-laboratory polysomnography was defined by apnea-hypopnea index (AHI) categories. Systolic and diastolic nondipping was defined by …

Continence Care: The Need For Creativity And Innovation, Karen A. Karlowicz

Ellmer School of Nursing Faculty Publications

(First paragraph) In April 2007, I attended a conference quite different from anything I had previously experienced. The conference, Innovating for Continence: The Engineering Challenge, was hosted by the Simon Foundation for Continence. As the title implies, this was not your usual conference about the diagnosis, treatment, and management of urinary incontinence. Rather, it was a conference dedicated to exploring technological advances in continence care. The central question throughout this two-and-a-half day event was, "What can be done to simulate continence technology to ensure the most effective management for persons who suffer with this problem?"

Micrornas (Mirnas) In Neurodegenerative Diseases, Peter T. Nelson, Wang-Xia Wang, Bernard W. Rajeev

Sanders-Brown Center on Aging Faculty Publications

Aging-related neurodegenerative diseases (NDs) are the culmination of many different genetic and environmental influences. Prior studies have shown that RNAs are pathologically altered during the inexorable course of some NDs. Recent evidence suggests that microRNAs (miRNAs) may be a contributing factor in neurodegeneration. miRNAs are brain-enriched, small (~22 nucleotides) non-coding RNAs that participate in mRNA translational regulation. Although discovered in the framework of worm development, miRNAs are now appreciated to play a dynamic role in many mammalian brain-related biochemical pathways, including neuroplasticity and stress responses. Research about miRNAs in the context of neurodegeneration is accumulating rapidly, and the goal of …

Reducing Hiv/Aids In Young People In Sub-Sahara Africa: Gaps In Research And The Role Of Theory, Kristien Michielsen, Marleen Bosmans, Marleen Temmerman

Obstetrics and Gynaecology, East Africa

This paper discusses the role of education in preventing HIV in children and young people in sub-Sahara Africa and presents the results of policy advisory research conducted on behalf of the Belgian Development Cooperation. The research consisted of a literature review and a field study in Rwanda. Relative to the high number of HIV prevention activities in sub-Sahara Africa, there is a limited number of scientific data on HIV risk reduction interventions for young people in this region. Longitudinal studies are especially scarce. Preliminary results show that many interventions have only a marginal impact on reducing sexual risk behaviour. Factors …

Successful Pregnancy Outcome Following Laparoscopic Myomectomy: Case Report, R. B. Parkar, Sikolia Wanyonyi, W. J. Kamau, D. Otieno

Obstetrics and Gynaecology, East Africa

Laparoscopic myomectomy is now widely used as an alternative to laparotomy in the management of symptomatic uterine fibroids. The advantages of this minimal access approach outweigh those of the open techniques. The pregnancy outcomes between the two methods have been studied and are comparable, but there still exists a lot of scepticism locally concerning this. It is against this background that we present a 31 year old nulliparous lady who had a two year history of primary infertility secondary to multiple uterine fibroids, the largest being fundal and measuring 6.6cm. She underwent a successful laparoscopic myomectomy in November, 2006 and …

Prevalence, Risk Factors And Outcome Of Acute Kidney Injury At The Aga Khan University Hospital Nairobi, Peter W. Munyu

Master of Medicine in Internal Medicine

Introduction: Acute kidney failure (acute kidney injury, AKI) is a group of syndromes that result in a decline in the glomerular filtration rate. In 2002, the Acute Dialysis Quality Initiative (ADQI) group proposed the RIFLE criteria to standardize the definitions of AKI severity and outcome. This criterion has been validated in several studies. AKI is frequently encountered in hospitalized patients; it has a negative impact on mortality and morbidity. A lot of work has been done to describe the epidemiology of AKI in developed countries. The same does not apply for developing countries. This study was designed to evaluate AKI …

Comparison Of Doppler Studies In Obstetrics With Fetal Outcome, Sheila Waa

Master of Medicine in Imaging and Diagnostic Radiology

Purpose: to compare umbilical artery and middle cerebral Doppler ultrasound values in normal and high risk pregnancies with fetal outcome. Method: 121 consecutive pregnancies (at or over 28 weeks gestation), stratified into low and high risk pregnancies based on clinician information were prospectively examined with doppler ultrasound of UA and MCA. Results: outcome was available for 100 of the 121 patients. 26% of pregnancies had poor outcome. Of these 73% (19) and 27% (7) were classified as high risk and low risk respectively. UA alone or in combination with MCA was shown to have 100% specificity for predicting fetal outcome. …

Sr-Bi Protects Against Endotoxemia In Mice Through Its Roles In Glucocorticoid Production And Hepatic Clearance, Lei Cai, Ailing Ji, Frederick C. De Beer, Lisa R. Tannock, Deneys R. Van Der Westhuyzen

Internal Medicine Faculty Publications

Septic shock results from an uncontrolled inflammatory response, mediated primarily by LPS. Cholesterol transport plays an important role in the host response to LPS, as LPS is neutralized by lipoproteins and adrenal cholesterol uptake is required for antiinflammatory glucocorticoid synthesis. In this study, we show that scavenger receptor B-I (SR-BI), an HDL receptor that mediates HDL cholesterol ester uptake into cells, is required for the normal antiinflammatory response to LPS-induced endotoxic shock. Despite elevated plasma HDL levels, SR-BI–null mice displayed an uncontrollable inflammatory cytokine response and a markedly higher lethality rate than control mice in response to LPS. In addition, …

Management Of The Neck In Differentiated Thyroid Cancer, David M. Cognetti, Edmund A. Pribitkin, William M. Keane

Department of Otolaryngology - Head and Neck Surgery Faculty Papers

Differentiated thyroid cancer is characterized by an excellent long-term prognosis, which unlike other head and neck carcinomas, is not influenced definitively by regional lymph node metastasis. The relative rarity of the disease, together with its tendency for delayed metastasis and its low mortality, makes a prospective randomized trial comparing treatment outcomes difficult. As a result, the effect of cervical lymph node metastases on survival is unclear, making meaningful recommendations for their management somewhat subjective. This article discusses guidelines for the management of the neck in differentiated.

Technical Assistance For Implementing Best Practices In The Asia And Near East Region, M.E. Khan, Sohini Roychowdhury, Mary Philip Sebastian, Sitanshu Sekhar Kar, Anurag Mishra, Vivek Sharma, G. Narayana, Bhawana Sharma, Nahla G. Abdel-Tawab, Ahmed Afifi

Reproductive Health

The Population Council's Frontiers in Reproductive Health (FRONTIERS) program offered technical assistance to any Asia Near East (ANE) country mission interested in funding adaptation of USAID‟s “best practices” in family planning or reproductive health. The ANE Bureau provided funding for the costs of FRONTIERS technical assistance. The overall objective of this study was to replicate and scale up "best practices" based on findings from FRONTIERS. The specific objectives were to institutionalize the Systematic Screening Instrument in the entire state of Uttarakhand, India; to strenghten emergency contraceptive pills service provision in Uttarakhand, India; and to enhance the use of Lactational Amenorrhea …

Sexual And Reproductive Health Needs Of Adolescents Perinatally Infected With Hiv In Uganda, Harriet Birungi, John Frank Mugisha, Juliana K. Nyombi, Francis Obare, Humphres Evelia, Hannington Nyinkavu

Reproductive Health

In Uganda, HIV/AIDS treatment, care and support programs are still organized around either adult or pediatric care and fail to adequately address the needs of adolescents, specifically perinatally-infected adolescents. This study, implemented jointly by the Population Council's Frontiers in Reproductive Health (FRONTIERS) program and the AIDS Support Organization (TASO), aimed to better understand the reproductive health and sexuality of this population group, and to identify anxieties or fears they have around entering social stages of adulthood. This study confirms that wide programmatic gaps exist in addressing the sexual and reproductive health needs of young people perinatally infected with HIV who …

Situation Analysis Of The Integration Of Family Planning Services In Postpartum, Postabortion And Prevention Of Mother To Child Transmission Programs In Nicaragua, Freddy Solis, Ana Del Carmen Rojas, Gadea Adilia, M. Estela Rivero-Fuentes, Ricardo Vernon

Reproductive Health

Between September 2005 and April 2007, FRONTIERS and Alva, a Nicaraguan consulting firm, conducted a situation analysis of the provision and use of contraceptive services in postpartum, postabortion and prevention of mother-to-child transmission of HIV (PMTCT) programs. The project‘s objective was to assess the degree to which contraceptive services were linked to postpartum, postabortion and PMTCT services and if this allowed the programs to meet the contraceptive needs of their clients. The project proposes recommendations for improving the quality of these programs.

Using Operations Research To Enhance Delivery Of Postpartum/Postabortion Family Planning Services In The Arab Region, Frontiers In Reproductive Health

Reproductive Health

The FRONTIERS program in Cairo organized a two-and-half day workshop to share programmatic experiences and lessons learned in integrating family planning with service providers from Egypt, Jordan, Sudan, and Yemen representing mid-level program managers and researchers. It was held in 2008 in tandem with a national end-of-project seminar for stakeholders in Egypt. Participants emphasized the need to capture missed opportunities in antenatal, delivery, postpartum or postabortion care by providing family planning services in all encounters between women and the health care system. They also agreed on an overarching need for operations research in assisting policy makers and program managers in …

Assessment Of Progress Of The Postabortion Care Initiative In Francophone Africa, Thierno Dieng, Mohamed Diadhiou, Nafissatou J. Diop, Youmane Niang Faye

Reproductive Health

The goals of this study were to assess the national situation concerning postabortion care (PAC) in six countries (Burkina Faso, Guinea, Mali, Niger, Senegal and Togo), including the process of introduction, integration and decentralization of PAC; the successes and obstacles in the process of introducing PAC; and recommended key steps to strengthen the introductory process. The study used two approaches: a comprehensive review of the introduction and institutionalization of PAC in the six countries, and a situation analysis of PAC services within each country.

Three Dimensional Echocardiography In Congenital Heart Defects., Girish S. Shirali

Manuscripts, Articles, Book Chapters and Other Papers

Three dimensional echocardiography (3DE) is a new, rapidly evolving modality for cardiac imaging. Important technological advances have heralded an era where practical 3DE scanning is becoming a mainstream modality. We review the modes of 3DE that can be used. The literature has been reviewed for articles that examine the applicability of 3DE to congenital heart defects to visualize anatomy in a spectrum of defects ranging from atrioventricular septal defects to mitral valve abnormalities and Ebstein's anomaly. The use of 3DE color flow to obtain echocardiographic angiograms is illustrated. The state of the science in quantitating right and left ventricular volumetrics …

Constructing 'Health', Defining 'Choice': Legal And Policy Perspetives On The Post-Pgd Embryo In Four Jurisdictions, Estair Van Wagner, Roxanne Mykitiuk, Jeff Nisker

Articles & Book Chapters

Through Preimplantation Genetic Diagnosis, embryos created by IVF are selected for transfer to a woman based on particular characterisations, including the presence of genetic markers or a tissue match for a sibling. In this paper we examine the precise language used in the recent policy and regulatory documents of four jurisdictions (the United Kingdom, Australia, Canada and New Zealand) that in any way characterises the post-PGD embryo. We then explore the mutually constructed relationship between how that embryo is characterised and the purposes for which PGD is applied, as well as the types of uses to which the post-PGD embryo …

Determining Standard Criteria For Endotracheal Suctioning In The Paediatric Intensive Care Patient: An Exploratory Study [Thesis], Kylie Davies

Theses: Doctorates and Masters

Endotracheal tube (ETT) suction is a common nursing procedure within the paediatric intensive care (PIC) setting. Significant side effects associated with this procedure can dramatically affect the stability of the critically ill ventilated paediatric patient. A comprehensive literature review failed to establish clear standards for determining when the procedure is warranted, especially in the paediatric population. This can present difficulty for the inexperienced paediatric intensive care nurse when assessing a patient's need for ETT suction. The aim of the research was to design an evidence based endotracheal suction assessment tool (ESAT) for use by nurses caring for paediatric patients. The …

The Effect Of Nurse Initiated Paracetamol On Emergency Department Patients With Pain From Low Acuity Injury, Joanne G. Wilson

Theses: Doctorates and Masters

Early identification and management of pain was identified at the commencement of this study as a key area requiring research in emergency departments. Prolonged waiting times for analgesia especially, was highlighted in the National Institute of Clinical Studies emergency department collaborative in 2003. Many barriers exist for a patient to receive analgesia. In Western Australia this is compounded by the legislation which restricts prescribing rights for nurses. Three considerations guided the development of the research project. Firstly, the patient has initial contact with the emergency department from the nurse at triage. Secondly, paracetamol was recognised as a potentially effective analgesic …

The Evaluation Of Midazolam On Head Injured Patients In The Prehospital Setting, Dragana Klinac

Theses: Doctorates and Masters

Midazolam (Hypnovel ®) is the only sedating agent used by paramedics at St John Ambulance Service W.A. in the management of many conditions including seizure activities, antisocial or uncontrollable behaviours, back pain incidents and head injuries. Midazolam, with a rapid absorption, fast onset of action and short duration on neurological activity, has been accepted as a safe and effective agent in prehospital treatment since the late-1990s. Often, if a patient is not complying with treatment or is uncontrollable or aggressive, paramedics are required to sedate the individual. This study primarily examines the use of midazolam for the sedation of unmanageable …

Antibiotic Susceptibility Of Pathogens Isolated From Patients With Community-Acquired Respiratory Tract Infections In Pakistan--The Active Study, Afia Zafar, Zahid Hussain, Eale Lomama, Sophie Sibille, Seema Irfan, Erum Khan

Department of Pathology and Laboratory Medicine

BACKGROUND: Respiratory tract infections (RTIs) are amongst the most wide spread and serious infections, accounting for over 50 million deaths globally each year. In developing countries, infants under 4 years of age are at greatest risk of lower RTIs, whereas in developed countries the severity of infection and rate of mortality are greater in elderly. The objective of the survey was to determine the in vitro susceptibility of antibiotics commonly prescribed RTIs against Streptococcus pneumoniae (SP), Haemophilus influenzae (HI) and Streptococcus pyogenes, isolated from patients with community-acquired RTIs globally. This survey involved 9 countries. In this study we present the …

Hepatic Angiosarcoma With Metastasis To Small Intestine, Zubair Ahmad, Azizun Nisa, Romana Idrees, Khurram Minhas, Shahid Pervez, Khalid Mumtaz

Department of Pathology and Laboratory Medicine

Hepatic angiosarcomas are rare tumours with poor prognosis, with patients usually dying within 6 months. Metastases mainly occur in lymph nodes, spleen, lungs, bones and adrenals. Metastasis to small intestine is even rarer. Similarly, primary or metastatic angiosarcomas in small intestine are extremely rare, often present with recurrent gastrointestinal bleeding and anemia, and have an extremely poor prognosis. Both primary or metastatic intestinal angiosarcomas may exhibit epithelioid morphology. It may be very difficult to differentiate between primary and secondary cases in intestine and especially when the tumour exhibits epithelioid morphology.
