Exploring social determinants of health on chemotherapy-induced peripheral neuropathy severity in ovarian cancer: An integrative review.

Ovarian cancer remains a significant public health concern for women despite advancements in cancer management. Despite comprising only 2.5 % of cancers in women, ovarian cancer ranks as the fifth leading cause of cancer-related deaths among women, with patients frequently receiving late diagnoses.

Conversation for change: engaging older adults as partners in research on gerotechnology.

There is increasing research and public policy investment in the development of technologies to support healthy aging and age-friendly services in Canada. Yet adoption and use of technologies by older adults is limited and rates of abandonment remain high. In response to this, there is growing interest within the field of gerotechnology in fostering greater participation of older adults in research and design.

Moving Toward the Promise of Participatory Engagement of Older Adults in Gerotechnology.

Limited uptake and use of developed technologies by older adults have prompted interest in participatory design and related approaches in the gerotechnology field. Despite this, recent systematic reviews suggest that researchers continue to passively engage older adults in research projects, often only providing advice or feedback in the early or later phases of research. A key barrier to more meaningful and active engagement of older adults is a lack of understanding as to how participatory design differs from other participatory approaches, and in particular, participatory action research.

Notes on the development of health psychology and behavioral medicine in the United States.

A "standard" historiographical overview of the development of health psychology in the United States, alongside behavioral medicine, first summarizes previous disciplinary and professional histories. A "historicist" approach follows, focussing on a collective biographical summary of accumulated contributions of one cohort (1967-1971) at State University of New York at Stony Brook. Foundational developments of the two areas are highlighted, contextualized within their socio-political context, as are innovative cross-boundary collaboration on "precursor" studies from the 1960s and 1970s, before the official disciplines emerged.

"A magical little pill that will relieve you of your womanly issues": What young women say about menstrual suppression.

Perceptions of menstruation by media discourses portray this bodily function to be messy, inconvenient, and as an unnecessary phenomenon to be controlled or possibly eliminated. Commercials shown on YouTube targeted toward young women suggest that having a monthly period is not healthy and a lifestyle that is menses free is both pharmacologically available and recommended in order to live a fuller life. We explored the meanings attached to online menstrual suppression commercials with 10 women aged between 18 and 25.

Drug testing in children with excessive daytime sleepiness during multiple sleep latency testing.

Study Objective: To determine the incidence of positive drug screens in children undergoing a multiple sleep latency test (MSLT) for evaluation of excessive daytime sleepiness (EDS).

Methods: A retrospective analysis was performed in children evaluated at the Boston Children's Hospital Sleep Center between 1998 and 2013 who underwent MSLT for EDS with a concurrent urine and/or serum drug screen.

Results: A total of 210 MSLTs were accompanied by drug testing.

Protein binding of lopinavir and ritonavir during 4 phases of pregnancy: implications for treatment guidelines.

Objective: To investigate the intraindividual pharmacokinetics (PKs) of total (protein bound plus unbound) and unbound lopinavir/ritonavir (LPV/RTV) and to assess whether the pediatric formulation (100 mg/25 mg) can overcome any pregnancy-associated changes.

Design: Prospective longitudinal PK study.

Methods: HIV-infected pregnant antiretroviral therapy-naive and experienced women receiving LPV/RTV 400 mg/100 mg tablets twice daily.

Pharmacokinetics of treprostinil diolamine in subjects with end-stage renal disease on or off dialysis.

Treprostinil diolamine sustained release (UT-15C SR) is being evaluated as an oral therapy for pulmonary arterial hypertension. This study evaluated the pharmacokinetics (PKs) of treprostinil following administration of UT-15C SR in subjects with end-stage renal disease (ESRD) compared with healthy subjects with normal renal function (NRF) and the effect of hemodialysis on the PK parameters of treprostinil. Eight ESRD subjects (requiring dialysis, mean creatinine clearance = 11.

Molecularly imprinted polymer sensors for detection in the gas, liquid, and vapor phase.

Fast, reliable, and inexpensive analytical techniques for detection of airborne chemical warfare agents are desperately needed. Recent advances in the field of molecularly imprinted polymers have created synthetic nanomaterials that can sensitively and selectively detect these materials in aqueous environments, but thus far, they have not been demonstrated to work for detection of vapors. The imprinted polymers function by mimicking the function of biological receptors.

Formation of benzoylecgonine isopropyl ester following solid-phase extraction.

In forensic toxicology general alkaline drug screens typically utilize liquid liquid [LLE] or solid phase extraction [SPE] sample preparation techniques. It is expected that different drugs will be detected when a laboratory changes techniques. In this study, when the authors switched from LLE to SPE they were able to detect benzoylecgonine [BE].

Penetration of tenofovir and emtricitabine in mucosal tissues: implications for prevention of HIV-1 transmission.

A mainstay of strategies to prevent HIV-1 transmission is to use antiretroviral therapy (ART) for pre-exposure prophylaxis (PrEP). Critical to the design and interpretation of PrEP prevention trials is the ability to make accurate pharmacological measurements of ART drugs in human genital and colorectal mucosal tissues, the principal route of HIV transmission. Here, we evaluated two drugs that are preferentially used for PrEP: tenofovir (TFV) disoproxil fumarate (TDF) and emtricitabine (FTC).

Comparison of tissue homogenate analytical results with and without standard addition.

Standard addition (SA) has occasionally been utilized as an analytical tool in forensic toxicology. It is recommended for difficult matrices such as tissue or decomposed specimens in which the accurate quantitation of drug may be problematic. However, the additional preparation time and increased use of specimen may limit its general applicability.

Comparison of liquid/liquid and solid-phase extraction for alkaline drugs.

The extraction of drugs from biological matrices is an essential specimen preparation step in current forensic postmortem laboratories. Traditionally, liquid/liquid extractions (LLE) were developed and employed to screen for the general unknown. However, solid-phase extractions (SPE) are becoming more popular as the availability of columns with suitable stationary phases increased.

Detection of drugs of forensic importance in postmortem bone.

There is a paucity of literature detailing the disposition of drugs in bone and bone marrow. Infrequently, in deaths involving skeletonized remains, fragmentation, decomposition, and exsanguination, traditional specimens may be unavailable for toxicological testing. This study examined the utility of bone for the detection of benzodiazepines, opiates, cocaine and metabolites, and basic drugs in 39 cases.

Prevalence of dihydrocodeine in hydrocodone positive postmortem specimens.

Hydrocodone (HC) has received renewed interest in the US due to reported increases in opiate related deaths involving psychotherapeutic drugs. The relative contribution of dihydrocodeine (DHC) in these deaths is unknown since little testing of this compound is performed. The objective of the study was to determine the prevalence of DHC in HC positive decedents and report the range of concentrations detected in these cases in order to evaluate the potential role of DHC in the deaths and determine the usefulness of including this analyte in opioid testing protocols.

Screening for cocaine metabolite fails to detect an intoxication.

Testing for the presence of cocaine (COC) is common in postmortem and clinical laboratories. COC use may be detected by screening urine specimens for COC metabolite. In the forensic arena, screening positive results are confirmed by a more specific and sensitive technique, such as gas chromatography-mass spectrometry.

A comparison of methadone, oxycodone, and hydrocodone related deaths in Northeast Ohio.

Increases in methadone and oxycodone related deaths have been recently documented in the United States. In response to these reports, the authors investigated cases over a six-year period in which postmortem toxicological analyses revealed the presence of methadone, hydrocodone, and oxycodone. The study was designed to determine whether regional methadone-associated mortality in Cuyahoga County reflected national trends and more specifically, to distinguish methadone mortality from other commonly used opioid analgesics.

Phencyclidine and cannabinoids in vitreous humor.

Vitreous humor (VH) is routinely collected at autopsy for the testing of electrolytes and ethanol. In recent years drugs of abuse have been detected in this specimen. In this study the authors assayed 30 VH samples for phencyclidine (PCP) and 50 specimens for cannabinoids.

A study of drug detection in a postmortem pediatric population.

At The Office of the Cuyahoga County Coroner (CCCO), Cleveland, Ohio, it is customary to perform an autopsy and conduct toxicological testing on decedents less than 19 years of age. This study provides a retrospective evaluation of drugs detected in a pediatric postmortem population between the years 1998 and 2002 (n = 730). Demographic information, cause and manner of death, and toxicological results were examined.

Comparison of drug concentrations in postmortem cerebrospinal fluid and blood specimens.

The concentration of drugs and metabolites in cerebrospinal fluid (CSF) and blood were determined in 282 autopsied cases using liquid-liquid extraction techniques and gas chromatographic analyses. All drugs were confirmed in one matrix by gas chromatography-mass spectrometry. CSF/blood ratios were used to compare the two biological fluids.

Cocaine and metabolites urinary excretion after controlled smoked administration.

Understanding cocaine and metabolites urinary excretion following smoking is important for interpretation of urine test results in judicial, workplace and treatment settings. In National Institute on Drug Abuse approved studies on a secure research unit, six subjects smoked placebo, 10, 20, and 40 mg cocaine with a precise dose delivery device and six different subjects smoked 42 mg cocaine in a glass pipe. Urine specimens (n = 700) were collected for up to seven days and analyzed for cocaine (COC), benzoylecgonine (BE), ecgonine methylester (EME), m-hydroxybenzoylecgonine (mOHBE), p-hydroxybenzoylecgonine (pOHBE), norbenzoylecgonine (NBE), and ecgonine (EC) by gas chromatography-mass spectrometry.
