Food Insecurity: Child Care Programs' Perspectives.

Background: Households experiencing "food insecurity" have limited access to food due to a lack of money or resources. Poor nutrition, from food insecurity, can impact physical and cognitive development of children. Study objectives were to document the prevalence of Tennessee child care programs screening for food insecurity, explore differences between programs receiving child and adult care food program (CACFP) funding and those screening for food insecurity, and understand possible burdens food insecurity places on child care families as perceived by child care program directors.

Modeling Bacterial Attachment Mechanisms on Superhydrophobic and Superhydrophilic Substrates.

Superhydrophilic and superhydrophobic substrates are widely known to inhibit the attachment of a variety of motile and/or nonmotile bacteria. However, the thermodynamics of attachment are complex. Surface energy measurements alone do not address the complexities of colloidal (i.

Exploration of the Role of the C-Terminal Domain of Human DNA Topoisomerase IIα in Catalytic Activity.

Human topoisomerase IIα (TOP2A) is a vital nuclear enzyme involved in resolving knots and tangles in DNA during replication and cell division. TOP2A is a homodimer with a symmetrical, multidomain structure. While the N-terminal and core regions of the protein are well-studied, the C-terminal domain is poorly understood but is involved in enzyme regulation and is predicted to be intrinsically disordered.

Quantifying interfacial substrate interactions via surface energy analyses.

Determination of a substrate's surface energy profile is a facile and inexpensive method to indicate the substrate's interfacial thermodynamics with another substance (e.g., microorganisms, biomacromolecules, medical devices, etc).

Cannabidiol and related cannabinoids are under exploration for the treatment of a number of disease states. The cannabinoid-quinone HU-331 has been studied as a potential anticancer therapeutic. Previous studies provide evidence that HU-331 displays anticancer activity without some of the known adverse events associated with traditional anticancer agents.

Thermodynamic Surface Analyses to Inform Biofilm Resistance.

Biofilms are the habitat of 95% of bacteria successfully protecting bacteria from many antibiotics. However, inhibiting biofilm formation is difficult in that it is a complex system involving the physical and chemical interaction of both substrate and bacteria. Focusing on the substrate surface and potential interactions with bacteria, we examined both physical and chemical properties of substrates coated with a series of phenyl acrylate monomer derivatives.

Predicting School Suspension Risk from Eighth through Tenth Grade Using the Strengths and Difficulties Questionnaire.

The current study examined (1) if the Strengths and Difficulties Questionnaire (SDQ) would yield alternative factor structures related to either symptoms or strengths with early adolescent students when an exploratory factor analysis (EFA) is used; (2) which scales best predicted suspensions of typically developing early adolescents; and (3) what cut-off scores were useful for identifying youth at risk for suspensions. The current study included 321 parent-student dyads, who were followed from the middle of eighth grade until the end of tenth grade. A symptoms-based EFA yielded three factors: Misbehavior, Isolation, and Agitation.

Effect of mobile text messages on antiretroviral medication adherence and patient retention in early HIV care: an open-label, randomized, single center study in south Florida.

Background: People with HIV (PHIV) with limited access to health services often experience suboptimal antiretroviral therapy (ART) adherence. We investigated whether a daily text messaging intervention improves ART adherence and retention in early HIV care in PHIV in a south Florida hospital-based clinic.

Methods: ART-naïve PHIV receiving care through the clinic's Ryan White HIV/AIDS Program were enrolled and randomly assigned to the intervention or control groups with a 1:1 ratio.

Loop diuretic resistance complicating acute heart failure.

Acute heart failure hospitalizations complicated by diuretic resistance are associated with worse outcomes. Yet, quantification of the frequency and accompanying risk from loop diuretic resistance is limited by the absence of a comprehensive definition with universal clinical application. Herein, we outline limitations of the current metrics used to identify and define diuretic resistance.

Examining the Impact of Antimicrobial Fluoroquinolones on Human DNA Topoisomerase IIα and IIβ.

Fluoroquinolones are a class of widely prescribed antibiotics with a broad range of activity against Gram-positive, Gram-negative, and some atypical microbes. Unfortunately, these drugs are associated with significant adverse events including neuropathy, tendinopathy, cardiac rhythm abnormalities, and mental health side effects. The mechanism by which fluoroquinolones cause many of these toxicities is unknown.

Educational Activity And Setting: Third-year pharmacy students enrolled in the two credit hour elective. Teaching methodology included didactic lecture, journal club, simulated addiction assignment with reflection, debates, external speakers, site visit to a residential drug court program and research paper with presentation.

Community Partners Join Forces: Battling Obesity and Diabetes Together.

Our objectives was to create an initiative to change the culture of a small community to improve quality of life as it relates to health for the residents through the use of health-related educational sessions, a coordinated fitness and nutrition program, and the construction of community fitness trails. We compared the use of a health-focused community driven program to the status quo in seeking opportunities to improve perception and understanding of one's health and overall quality of life for participants. Among the various techniques identified to improve a community's health outcomes, dissemination of information through the use of educational sessions empowered citizens to take control of their health status, and ultimately, their quality of life.

Two-Mechanism Model for the Interaction of Etoposide Quinone with Topoisomerase IIα.

Topoisomerase II is an essential nuclear enzyme involved in regulating DNA topology to facilitate replication and cell division. Disruption of topoisomerase II function by chemotherapeutic agents is in use as an effective strategy to fight cancer. Etoposide is an anticancer therapeutic that disrupts the catalytic cycle of topoisomerase II and stabilizes enzyme-bound DNA strand breaks.

Development and implementation of a multitiered health informatics curriculum in a college of pharmacy.

Standards requiring education in informatics in pharmacy curricula were introduced in the last 10 years by the Accreditation Council for Pharmacy Education. Mirroring difficulties faced by other health professions educators, implementation of these requirements remains fragmented and somewhat limited across colleges of pharmacy in the US. Clinical practice and workforce metrics underline a pronounced need for clinicians with varying competencies in health informatics.

Pain and Agitation Management in Critically Ill Patients.

Pain and agitation may be difficult to assess in a critically ill patient. Pain is best assessed by self-reporting pain scales; but in patients who are unable to communicate, behavioral pain scales seem to have benefit. Patients' sedation level should be assessed each shift and preferably by a validated ICU tool, such as the RASS or SAS scale.

Is irritable bowel syndrome an infectious disease?

Irritable bowel syndrome (IBS) is the most common of all gastroenterological diseases. While many mechanisms have been postulated to explain its etiology, no single mechanism entirely explains the heterogeneity of symptoms seen with the various phenotypes of the disease. Recent data from both basic and clinical sciences suggest that underlying infectious disease may provide a unifying hypothesis that better explains the overall symptomatology.

Cognitive and Performance Enhancing Medication Use to Improve Performance in Poker.

Use of neuroenhancers has been studied in groups ranging from students to surgeons; however, use of cognitive and performance enhancing medications (CPEMs) to improve performance in poker has remained largely overlooked. To assess the use of CPEMs to improve poker performance, a survey of poker players was conducted. Participants were recruited via Internet poker forums; 198 completed the online survey.

Emerging therapeutic options for the management of hepatitis C infection.

Until recently the traditional treatment for hepatitis C infection included pegylated interferon and ribavirin combination therapy. The sustained virological response (SVR) seen with this combination is poor and requires lengthy treatment to achieve. Additionally, significant side effects and numerous contraindications prevented many patients from being successfully treated with this therapy.

Opioids and efflux transporters. Part 4: influence of N-substitution on P-glycoprotein substrate activity of noroxymorphone analogues.

The efflux transporter protein P-glycoprotein (P-gp) is capable of affecting the central distribution of diverse neurotherapeutics, including opioid analgesics, through their active removal from the brain. P-gp located at the blood brain barrier has been implicated in the development of tolerance to opioids and demonstrated to be up-regulated in rats tolerant to morphine and oxycodone. We have previously examined the influence of hydrogen-bonding oxo-substitutents on the P-gp-mediated efflux of 4,5-epoxymorphinan analgesics, as well as that of N-substituted analogues of meperidine.
