Cognitive Problems and Their Clinical Assessment in Systemic Lupus Erythematosus: Contrasting Patient and Provider Views.

Objective: Systemic lupus erythematosus (SLE) is a complex chronic disease associated with reduced cognitive functioning. Patients with SLE report cognitive symptoms, but cognitive assessment is not routine in SLE and little is known about day-to-day cognitive problems and their effect on disease management. As part of a pilot exploring the use of a cognitive functioning report prototype for shared decision-making in clinical encounters (the Approaches to Positive Patient-Centered Experiences of Aging in Lupus [APPEAL] Study), we investigated the relevance of cognitive assessments performed using the National Institutes of Health (NIH) Toolbox among patients with SLE.

Self-management of Epilepsy: A Systematic Review.

Background: Although self-management is recommended for persons with epilepsy, its optimal strategies and effects are uncertain.

Purpose: To evaluate the components and efficacy of self-management interventions in the treatment of epilepsy in community-dwelling persons.

Data Sources: English-language searches of MEDLINE, Cochrane Central Register of Controlled Trials, PsycINFO, and CINAHL in April 2018; the MEDLINE search was updated in March 2019.

Clinical Outcomes of Metformin Use in Populations With Chronic Kidney Disease, Congestive Heart Failure, or Chronic Liver Disease: A Systematic Review.

Background: Recent changes to the U.S. Food and Drug Administration boxed warning for metformin will increase its use in persons with historical contraindications or precautions.

Low Molecular Weight Opioid Peptide Esters Could be Developed as a New Class of Analgesics.

Low molecular weight opioid peptide esters (OPE) could become a class of analgesics with different side effect profiles than current opiates. OPE may have sufficient plasma stability to cross the blood brain barrier (BBB), undergo ester hydrolysis and produce analgesia. OPE of dipeptides, tyr-pro and tyr-gly conjugated to ethanol have a structure similar to the anesthestic agent, etomidate.

Stereocomplexes Formed From Select Oligomers of Polymer d-lactic Acid (PDLA) and l-lactate May Inhibit Growth of Cancer Cells and Help Diagnose Aggressive Cancers-Applications of the Warburg Effect.

It is proposed that select oligomers of polymer d-lactic acid (PDLA) will form a stereocomplex with l-lactate in vivo, producing lactate deficiency in tumor cells. Those cancer cells that utilize transport of lactate to maintain electrical neutrality may cease to multiply or die because of lactate trapping, and those cancer cells that benefit from utilization of extracellular lactate may be impaired. Intracellular trapping of lactate produces a different physiology than inhibition of LDH because the cell loses the option of shuttling pyruvate to an alternative pathway to produce an anion.

Selected Gamma Aminobutyric Acid (GABA) Esters may Provide Analgesia for Some Central Pain Conditions.

Central pain is an enigmatic, intractable condition, related to destruction of thalamic areas, resulting in likely loss of inhibitory synaptic transmission mediated by GABA. It is proposed that treatment of central pain, a localized process, may be treated by GABA supplementation, like Parkinson's disease and depression. At physiologic pH, GABA exists as a zwitterion that is poorly permeable to the blood brain barrier (BBB).

Stereochemical basis for a unified structure activity theory of aromatic and heterocyclic rings in selected opioids and opioid peptides.

This paper presents a novel unified theory of the structure activity relationship of opioids and opioid peptides. It is hypothesized that a virtual or known heterocyclic ring exists in all opioids which have activity in humans, and this ring occupies relative to the aromatic ring of the drug, approximately the same plane in space as the piperidine ring of morphine. Since the rings of morphine are rigid, and the aromatic and piperidine rings are critical structural components for morphine's analgesic properties, the rigid morphine molecule allows for approximations of the aromatic and heterocyclic relationships in subsequent drug models where bond rotations are common.

Transfusion of sickle cells may be a therapeutic option for patients suffering metastatic disease.

Red blood cells from patients with sickle cell disease will sickle under conditions of hypoxemia and acidosis which is a similar milieu found in malignant tumors. While control of tumor angiogenesis has long been a goal of cancer therapy, selective occlusion of tumor blood supply may be achieved by transfusion of sickle cells into patients who suffer metastatic cancer. Although this potential therapy has not been previously reported in the medical literature, the concept may have been elusive to medical mainstream thinking because it requires transfusion of diseased cells.
