A retrospective study of adverse drug events in anticoagulant administration with relevance to COVID-19.

Initial studies in COVID-19 patients reported lower mortality rates associated with the use of the drug heparin, a widely used anticoagulant. The objective of this analysis was to determine whether there are adverse events associated with the administration of anticoagulants, and specifically how this might apply in patients known to have COVID-19. Data for this study were obtained from the Food and Drug Administration's Adverse Event Reporting System (FAERS) public database and from the NIH's clinical trials website.

Antipsychotic factors related to time to competency for forensic inpatients in a state psychiatric facility.

Introduction: A defendant who is deemed incompetent to stand trial may go through competency restoration consisting of mental health treatment and legal education. Antipsychotics are often used in treatment; however, there is little data examining their role.

Methods: This retrospective study included subjects opined competent to stand trial from July 2016 to February 2020 and prescribed an antipsychotic.

Context dependent effects of ascorbic acid treatment in TET2 mutant myeloid neoplasia.

Loss-of-function TET2 mutations (TET2) are common in myeloid neoplasia. TET2, a DNA dioxygenase, requires 2-oxoglutarate and Fe(II) to oxidize 5-methylcytosine. TET2 thus result in hypermethylation and transcriptional repression.

Identifying Predictors of Primary Adherence to Second Generation Long-Acting Injectable Antipsychotics Following Discharge from an Acute Inpatient Psychiatry Unit.

Objectives: Describe primary adherence and medication persistence to second generation long-acting injectable (LAI) antipsychotics following an inpatient psychiatry hospitalization, compare rates of psychiatric-related hospital readmissions and emergency visits within 6 months of discharge between patients who were adherent versus nonadherent, and explore predictors of primary adherence to second generation LAI antipsychotics following hospitalization.

Experimental Design: This retrospective chart review included patients who received at least 1 dose of a second-generation LAI antipsychotic while hospitalized in an acute care psychiatry unit between April 1, 2016 and July 31, 2017, had active Missouri Medicaid, and continued on the second-generation LAI antipsychotic upon discharge. Patients were excluded if they were discharged to a care setting where medication was administered.

Accuracy of Medical Marijuana Claims Made by Popular Websites.

Background: With increasing popularity of marijuana, consumers are likely turning to the internet for information regarding medical marijuana. Accuracy of medical marijuana claims is a significant concern because consumers change their medication management based on information from a single website.

Objective: The purpose of this study was to evaluate the accuracy and quality of medical marijuana claims on popular websites.

Inpatient Proton Pump Inhibitor Administration and Hospital-Acquired Clostridium difficile Infection: Evidence and Possible Mechanism.

The incidence of Clostridium difficile infection continues to increase globally. Particularly concerning are hospital-acquired cases that attribute significant morbidity, mortality, and expenditures to the health care system. Proton pump inhibitors, which are widely prescribed and generally considered to have minimal adverse effects, have recently come under scrutiny for positive associations with C.

Pharmacogenomics of triazole antifungal agents: implications for safety, tolerability and efficacy.

Triazole antifungal agents are prescribed to treat invasive fungal infections in neutropenic and non-neutropenic patients. These antifungal agents are substrates and inhibitors of cytochrome P450 (CYP). Genetic polymorphisms in CYP2C9, CYP2C19 and CYP3A5 can lead to large population-specific variations in drug efficacy and safety, optimal dosing, or contribute to drug interactions associated with this class.

Maternal urinary phthalates and sex-specific placental mRNA levels in an urban birth cohort.

Background: Prenatal urinary concentrations of phthalates in women participants in an urban birth cohort were associated with outcomes in their children related to neurodevelopment, autoimmune disease risk, and fat mass at 3,5,7, and 8 years of life. Placental biomarkers and outcomes at birth may offer biologic insight into these associations. This is the first study to address these associations with candidate genes from the phthalate and placenta literature, accounting for sex differences, and using absolute quantitation methods for mRNA levels.

Transporter effects on cell permeability in drug delivery.

The role of drug transporters as one of the determinants of cellular drug permeability has become increasingly evident. Despite the lipophilicity of a drug molecule as rate-limiting factor for passive diffusion across biological membranes, carrier-mediated and active transport have gained attention over the years. A better understanding of the effects and roles of these influx transporters towards transmembrane permeability of a drug molecule need to be delineated for drug development and delivery.

Cost-avoidance and qualitative analysis of clinical pharmacy interventions by psychiatric pharmacy residents at state psychiatric facilities.

Purpose: The cost avoidance and quality of clinical interventions made by postgraduate year 2 (PGY2) psychiatric pharmacy residents are analyzed.

Methods: A retrospective database review of clinical interventions made by PGY2 psychiatric pharmacy residents in two state psychiatric facilities from July 1, 2007 through June 30, 2014, was conducted using a clinical intervention documentation software system. Cost avoidance was calculated by multiplying the mean cost of an adverse drug reaction (ADR) by the probability of an ADR occurring had the intervention not occurred.

Family Commitment and Work Characteristics among Pharmacists.

Factors associated with family commitment among pharmacists in the south central U.S. are explored.

The Influence of Influenza and Pneumococcal Vaccines on Community-Acquired Pneumonia (CAP) Outcomes Among Elderly Patients.

Elderly are at high risk for hospitalization for community-acquired pneumonia (CAP), especially due to Streptococcus pneumoniae, and seasonal influenza viruses. Data suggest PPV23's influence on various CAP-related outcomes among the elderly may depend upon how many years have elapsed since they received this vaccine. PPV23's protection against invasive pneumococcal disease and CAP hospitalizations are often limited to moderately ill elderly, who are less than 75 years old, or female.

Molecular mechanisms involved in HIV-1 Tat-mediated induction of IL-6 and IL-8 in astrocytes.

Background: HIV-associated neurocognitive disorders (HAND) exist in approximately 50% of infected individuals even after the introduction of highly active antiretroviral therapy. HIV-1 Tat has been implicated in HIV-associated neurotoxicity mediated through production of pro-inflammatory cytokines like IL-6 and IL-8 by astrocytes among others as well as oxidative stress. However, the underlying mechanism(s) in the up-regulation of IL-6 and IL-8 are not clearly understood.

HIV-1 Tat-mediated induction of CCL5 in astrocytes involves NF-κB, AP-1, C/EBPα and C/EBPγ transcription factors and JAK, PI3K/Akt and p38 MAPK signaling pathways.

The incidence of HIV-associated neurological disorders (HAND) has increased during recent years even though the highly active antiretroviral therapy (HAART) has significantly curtailed the virus replication and increased the life expectancy among HIV-1 infected individuals. These neurological deficits have been attributed to HIV proteins including HIV-1 Tat. HIV-1 Tat is known to up-regulate CCL5 expression in mouse astrocytes, but the mechanism of up-regulation is not known.

Bioanalytical method validation of rapamycin in ocular matrix by QTRAP LC-MS/MS: application to rabbit anterior tissue distribution by topical administration of rapamycin nanomicellar formulation.

A novel, fast and sensitive 3200 QTRAP LC-MS/MS method was validated for rapamycin analysis in the rabbit eye following 0.2% administration of nanomicellar eye drop formulation. The LC-MS/MS technique was developed with electrospray ionization (ESI) in positive mode.

Involvement of metabotropic glutamate receptor 5, AKT/PI3K signaling and NF-κB pathway in methamphetamine-mediated increase in IL-6 and IL-8 expression in astrocytes.

Methamphetamine (MA) is one of the commonly used illicit drugs and the central nervous system toxicity of MA is well documented. The mechanisms contributing to this toxicity have not been fully elucidated. In this study, we investigated the effect of MA on the expression levels of the proinflammatory cytokines/chemokines, IL-6 and IL-8 in an astrocytic cell line.

The conference was held in Gangzhou, China on 24-26 July 2011 and shared a venue with the Society of Chinese Bioscientists in America Thirteenth International Symposium. Over 150 participants from the Americas, Europe, Asia and Australia attended the meeting.

HIV-1 envelope protein gp120 up regulates CCL5 production in astrocytes which can be circumvented by inhibitors of NF-κB pathway.

HIV associated neurological disorders (HAND) is a common neurological complication in patients infected with HIV. The proinflammatory cytokines and chemokines produced by astrocytes play a pivotal role in neuroinflammatory processes in the brain and viral envelope gp120 has been implicated in this process. In view of increased levels of CCL5 observed in the CSF of HIV-1 infected patients, we studied the effects of gp120 on CCL5 expression in astrocytes and the possible mechanisms responsible for those effects.

HIV-1 gp120-mediated increases in IL-8 production in astrocytes are mediated through the NF-κB pathway and can be silenced by gp120-specific siRNA.

Background: The exact mechanism underlying HIV-associated neurocognitive disorders still remains largely unresolved. However, viral genes (for example gp120 and tat) and their effect on cytokine/chemokine expressions have been linked with neuroinflammation. Conversely, interlekin-8 (IL-8) is a known proinflammatory chemokine and is known to be over-expressed in human brain microvascular endothelial cells in response to gp120.

Modulation of peripheral inflammation in sensory ganglia by nuclear factor (kappa)B decoy oligodeoxynucleotide: involvement of SRC kinase pathway.

Nuclear factor kappa B (NF(kappa)B) transcription factor plays a key role in the expression of many genes involved in the inflammatory process. We used the Freund's Complete Adjuvant (FCA)-induced model of peripheral inflammation to investigate the anti-inflammatory effects of double stranded oligodeoxynucleotides (ODN) with consensus NF(kappa)B sequence as transcription factor decoys to inhibit NF(kappa)kappaB activation in the dorsal root ganglia (DRG). Local administration of the wild-type-, but not mutant-ODN decoy, dose-dependently inhibited edema formation and paw withdrawal latency as a measure of hyperalgesic response induced by FCA in rat paw.
