In The Postoperative Cardiothoracic Surgical Patient Being Mechanically Ventilated, Is There A Difference In Outcomes When Comparing Sedation With Dexmedetomidine Versus Propofol?, Benjamin Heinrich Riebesel 2016 University of Southern Mississippi

In The Postoperative Cardiothoracic Surgical Patient Being Mechanically Ventilated, Is There A Difference In Outcomes When Comparing Sedation With Dexmedetomidine Versus Propofol?, Benjamin Heinrich Riebesel

Doctoral Nursing Capstone Projects

Patients undergoing a cardiothoracic operation typically require mechanical ventilation in the postoperative phase. Each year approximately 395,000 of these operations are performed in the United States alone. As many as 10% of these patients require reoperation within the first few hours of recovery due to complications (Barash & Cullen, 2013). This comprehensive review of the literature was performed to determine whether postoperative sedation with dexmedetomidine leads to better patient outcomes than sedation with propofol. Inclusion criteria included publications written in the English language, articles available in full text, articles written within the last 10 years, and publications with a focus ...


Environmental Signaling Through The Target Of Rapamycin Complex 1 (Torc1) And The Regulation Of Epigenetic Mechanisms, Jason J. Workman 2016 University of Tennessee Health Science Center

Environmental Signaling Through The Target Of Rapamycin Complex 1 (Torc1) And The Regulation Of Epigenetic Mechanisms, Jason J. Workman

Theses and Dissertations (ETD)

The gene expression profile of a eukaryotic cell is responsive to a variety of extracellular stimuli, including nutrient availability, which allows cells to toggle between anabolism and catabolism based on the favorability of their environment. Much of this information is relayed through signaling complexes, such as the target of rapamycin complex 1 (TORC1), to downstream chromatin modifying enzymes. These enzymes impact the gene regulatory process through altered histone post-translation modifications, changes in chromatin structure, and docking of chromatin regulatory complexes. Yet, despite preliminary studies suggesting that TORC1 affects epigenetic mechanisms, including histone H3 lysine 56 acetylation (H3K56ac), almost nothing is ...

Vulvodynia; An Under-Recognized Disease, Simona Roxana Georgescu, Cristina I. Mitran, Mădălina I. Mitran, Maria I. Sârbu, Mircea Tampa 2016 Carol Davila University, Department of Dermatology and Venereology

Vulvodynia; An Under-Recognized Disease, Simona Roxana Georgescu, Cristina I. Mitran, Mădălina I. Mitran, Maria I. Sârbu, Mircea Tampa

Journal of Mind and Medical Sciences

Vulvodynia is a chronic condition which affects an increasing number of women; it presents currently an incidence that is higher than had previously been estimated. Regarding pathogenesis, several (hormonal, infectious, inflammatory and psychological) factors have been proposed, but vulvodynia etiology remains still unclear. This disorder is a multifactorial condition with a significant impact on the patient’s quality of life, yet is difficult to diagnose (an under-estimated/ under-recognized affection). Certain medical investigations are required in order to exclude other diseases (the diagnosis of vulvodynia being one of exclusion), but anamnesis and physical examination are essential steps in the diagnosis.

Although ...


Structural Dichotomy Of The Mind; The Role Of Sexual Neuromodulators, Ion G. Motofei, David L. Rowland 2016 Carol Davila University, Department of Surgery and Psychiatry

Structural Dichotomy Of The Mind; The Role Of Sexual Neuromodulators, Ion G. Motofei, David L. Rowland

Journal of Mind and Medical Sciences

The mind (mental function) and sexuality represent two distinct environmental functions, but which are supported within the brain by a common (somatic-autonomic) neurobiological substrate. As a consequence, mental function takes on autonomic characteristics from the sexual-autonomic system (like autonomy, duality), while sexual function takes on features from mental functioning (such as lateralization). In this paper we discuss the lateralized action of two classes of sexual neuromodulators: hormones and pheromones. This process of lateralization is assimilated with the structural dichotomy of the mind.

A relatively similar process but related to informational dichotomy of the mind will be presented in a forthcoming ...

The Current Treatment Of Erectile Dysfunction, Maria Isabela Sarbu, Mircea Tampa, Mădălina I. Mitran, Cristina I. Mitran, Vasile Benea, Simona R. Georgescu

Journal of Mind and Medical Sciences

Erectile dysfunction (ED) is the inability to achieve and maintain an erection sufficient for satisfactory sexual intercourse. It is the most frequent sexual dysfunction in elderly men and its prevalence increases with age.

Ever since ED was recognized as a real health problem, several treatment options became available and some of them proved to be very efficient. PDE5 inhibitors are the mainstay treatment of ED.

However, other treatment options such as intracorporal injections, surgery, vacuum devices and prosthesis are also available for patients who are unresponsive to PDE5 inhibitors. Since none of the treatment options available so far has proven ...

The Substrate Of The Biopsychosocial Influences In The Carcinogenesis Of The Digestive Tract, Georgică C. Târtea, Cristina Florescu, Daniel Pirici, Daniel Caragea, Elena A. Târtea, Cristin C. Vere

Journal of Mind and Medical Sciences

Digestive cancer represents a severe public health problem, being one of the main causes of death. It is considered a multifactorial disease, with hereditary predisposition, environmental factors, and other factors involved in carcinogenesis. Both the evolution and the pathogenesis of digestive neoplasms remain incompletely elucidated. As a multifactorial disease, it can be approached by taking into account the biopsychosocial influences via enteric nervous system. Many peptides and non-peptides having a neurotransmitter role can be found in the enteric nervous system, which can influence the neoplastic process directly or indirectly by affecting some angiogenic, growth, and metastasis factors. However, neurotransmitters can ...

As a 5-α reductase inhibitor, Finasteride has proven effective in ameliorating two conditions documented to be androgen dependent, namely male androgenic alopecia and benign prostatic hyperplasia. Therapeutic results are maintained as long as the drug is administered, with treatment cessation generally leading to the return of symptomatology for each condition. In addition, during the therapeutic phase, several adverse effects have been reported, some of which persist long or indefinitely after treatment cessation, known as “post-finasteride syndrome.”

Herein we present and discuss the most common finasteride side effects, along with a psycho-neuroendocrine rationale that could explain the persistence of many adverse ...

Cardiomems™ In Lvad Patients: A Case Series, Maya Guglin, Bennet George, Sarah Branam, Amanda Hart

The VAD Journal

Patients with a left ventricular assist device (LVAD) commonly encounter issues with volume status post-implant. Volume overload can result from incomplete compensation of left ventricular failure or from right ventricular failure. The CardioMEMS™ intracardiac hemodynamic monitoring device is an area of growing interest regarding the management of chronic congestive heart failure, however, its utility has not been serially investigated in patients with an LVAD. We present a case series of patients with ventricular assist devices care for at our institution in which the CardioMEMS™ device aided in the management of volume status and pump performance.

Inappropriate prescribing for ARI and diarrhoea is a serious health problem in many developing countries including Bangladesh. A baseline retrospective prescribing survey for ARI and diarrhoea have been conducted in randomly selected 60 thana health complexes (THCs) of Dhaka division of Bangladesh. In the 38 of 60 THCs, the prescribers did not comply with the standard treatment guidelines (STG) for ARI. They are marked as 'unsatisfactory performers'. In these THCs unnecessary antibiotics were prescribed in more than 50% of the encounters. The study further revealed that in 26 THCs, comprising 41.6% of the 38 THCs, the situation was even ...

Microbiology, Immunology, and Tropical Medicine Faculty Publications

BACKGROUND: Even though human hookworm infection is highly endemic in many countries throughout the world, its global economic and health impact is not well known. Without a better understanding of hookworm's economic burden worldwide, it is difficult for decision makers such as funders, policy makers, disease control officials, and intervention manufacturers to determine how much time, energy, and resources to invest in hookworm control.

METHODOLOGY/PRINCIPLE FINDINGS: We developed a computational simulation model to estimate the economic and health burden of hookworm infection in every country, WHO region, and globally, in 2016 from the societal perspective. Globally, hookworm infection ...

Characterizing respiratory rate variability (RRV) in humans during sleep is challenging, since it requires the analysis of respiratory signals over a period of several hours. These signals are easily distorted by movement and volitional inputs. We applied the method of spectral analysis to the nasal pressure transducer signal in 38 adults with no obstructive sleep apnea, defined by an apnea‐hypopnea index <5, who underwent all‐night polysomnography (PSG). Our aim was to detect and quantitate RRV during the various sleep stages, including wakefulness. The nasal pressure transducer signal was acquired at 100 Hz and consecutive frequency spectra were generated for the length of the PSG with the Fast Fourier Transform. For each spectrum, we computed the amplitude ratio of the first harmonic peak to the zero frequency peak (H1/DC), and defined as RRV as (100 − H1/DC) %. RRV was greater during wakefulness compared to any sleep stage, including rapid‐eye‐movement. Furthermore, RRV correlated with the depth of sleep, being lowest during N3. Patients spent most their sleep time supine, but we found no correlation between RRV and body position. There was a correlation between respiratory rate and sleep stage, being greater in wakefulness than in any sleep stage. We conclude that RRV varies according to sleep stage. Moreover, spectral analysis of nasal pressure signal appears to provide a valid measure of RRV during sleep. It remains to be seen if the method can differentiate normal from pathological sleep patterns.

BACKGROUND

ACT is commonly used for heparin anticoagulation monitoring during procedures including cardiopulmonary bypass surgery, coronary angioplasty, and interventional radiology. To prevent thrombosis, moderate to high levels of heparin anticoagulation are required. The Hemochron Signature Elite (HSE, Accriva Diagnostics, formerly ITC, San Diego, CA) was implemented at TJUH as a replacement for the older model Hemochron Response (Accriva/ITC Model HRS.110, San Diego, CA). Operating room (OR) perfusionists reported irreproducible high results using HSE that could not be explained clinically. In consideration of use of i-STAT analyzers (Abbott Point of Care, Princeton, NJ) as an alternative to HSE, we ...

BACKGROUND

The epoc Blood Analysis System (Alere, Orlando, FL) performs blood gases, electrolytes, and metabolites using a Blood Gas Electrolyte and Metabolite (BGEM) Test Card panel on 92 uL of whole blood. The BGEM test card uses potentiometric sensors to measure sodium, potassium, ionized calcium, pH, pCO2; amperometric sensors to measure pO2, glucose, and lactate; and a conductometric sensor to measure hematocrit. Results are available in 3-10 minutes, depending upon the time between calibration and patient testing. TJUH implemented the epoc in its ICUs in 2012 to provide Point of Care (POC) results. Alere recently added creatinine and chloride sensors ...


Sample Size Formulas For Estimating Intraclass Correlation Coefficients In Reliability Studies With Binary Outcomes, Mengxiao Xu 2016 The University of Western Ontario

Sample Size Formulas For Estimating Intraclass Correlation Coefficients In Reliability Studies With Binary Outcomes, Mengxiao Xu

Electronic Thesis and Dissertation Repository

Introduction: Measurement errors can seriously affect quality of clinical practice and medical research. It is therefore important to assess such errors by conduct- ing studies to estimate a coefficients reliability and assessing its precision. The intraclass correlation coefficient (ICC), defined on a model that an observation is a sum of information and random error, has been widely used to quantify reliability for continuous measurements. Sample formulas have been derived for explicitly incorporation of a prespecified probability of achieving the prespecified precision, i.e., the width or lower limit of a confidence interval for ICC. Although the concept of ICC is ...
