Pharmacokinetics and pharmacodynamics of drugs in elderly individuals differ from those in younger adults; thus, adverse drug events (ADEs) are common in older patients with polypharmacy because co-existing comorbidities elevate the risk of ADEs occurring. However, ADEs have not yet been characterised based on the elderly patients of Japanese origin and polypharmacy.

The 100 most commonly reported ADEs were grouped into four classes (Class 1-Class 4) based on elderly patients with polypharmacy.

In this study, logistic regression analysis was performed using cases recorded in the Japanese Adverse Drug Event Report (JADER) database.

ADEs in elderly patients treated with polypharmacy-in whom the risk of electrolyte abnormalities, renal and respiratory disorders, and coagulopathy was high-were categorised as 'Class 1 [E(+), P(+)]', while ADEs in elderly patients not treated with polypharmacy-in whom the risk of delirium and fall was high-were categorised as 'Class 2 [E(+), P(-)]'. When there was no association with being elderly, ADEs associated with polypharmacy that carried a high risk of myelosuppression and infection were categorised as 'Class 3 [E(-), P(+)]', and allergic ADEs that were not affected by being elderly or polypharmacy, were categorised as 'Class 4 [E(-), P(-)]'. Class 1 events as well as Class 3 ADEs occurred more frequently in females than in males, whereas Class 3 ADEs (deep vein thrombosis and pulmonary embolism) occurred more frequently in males.

Class 1 and Class 2 ADEs should be investigated in analyses that focus on individual drugs.

Darunavir is a human immunodeficiency virus type 1 (HIV-1) protease inhibitor boosted with ritonavir (DRV/r) or cobicistat.

This study provided continued access to DRV/r and assessed long-term safety in patients aged 3 to <18 years.

Patients who had completed treatment in the DELPHI (TMC114-C212), DIONE (TMC114-TiDP29-C230), or ARIEL (TMC114-TiDP29-C228) studies were eligible to participate if they derived benefit from using DRV/r in countries where it was not available to them. TAK-715 datasheet DRV/r dosing was continued based on original study protocols. Only safety data were collected. Reportable adverse events (AEs) included AEs considered at least possibly related to treatment with DRV/r, AEs leading to discontinuation or treatment interruption, and serious AEs (SAEs).

Forty-six patients rolled over to this study and received at least one dose of DRV/r. Median duration of DRV/r intake was 4.2 years. Overall, 15/46 patients experienced one or more reportable AEs, 10/46 patients experienced one or more grade 3 or 4 AEs, and 12/46 patients experienced one or more SAEs. The most common grade 3 or 4 and SAEs were pneumonia (3/46) and asthma (2/46). Only one AE (grade 1 lipoatrophy) was considered probably related to DRV/r (DIONE, n = 1). Overall, 3/46 patients experienced an HIV-related AE (grade 3 pneumonia SAE; grade 2 tuberculosis SAE, and grade 2 lipoatrophy AE), none of which were considered related to DRV/r or led to study discontinuation. Two AEs leading to discontinuation were pregnancies.

These long-term safety results continue to support DRV/r as a valuable therapeutic option for the treatment of HIV-1 infection in pediatric patients aged ≥3years.

Isthmin1 (ism1) is a secreted protein whose gene expression pattern coincides with that of early dorsal determinants, nodal ligand genes like sqt and cyc, and with fgf8 during various phases of zebrafish development. Ism1 functions in early embryonic patterning and development are poorly understood; however, it has recently been shown to interact with nodal pathway genes to control organ asymmetry in chicken. Here, we show that misexpression of ism1 deletion constructs disrupts embryonic patterning in zebrafish and exhibits genetic interactions with both Fgf and nodal signaling. Unlike Fgf and nodal pathway mutants, CRISPR/Cas9-engineered ism1 mutants did not show obvious developmental defects. Further, in vivo single molecule fluorescence correlation spectroscopy (FCCS) showed that Ism1 diffuses freely in the extra-cellular space, with a diffusion coefficient similar to that of Fgf8a; however, our measurements do not support direct molecular interactions between Ism1 and either nodal ligands or Fgf8a in the developing zebrafish embryo. Together, data from gain- and loss-of-function experiments suggest that zebrafish Ism1 plays a complex role in regulating extracellular signals during early embryonic development.

Although automated pupillometry is increasingly used in critical care settings, predictive value of automatically assessed pupillary parameters during different intracranial pressure (ICP) levels and possible clinical implications are unestablished.

This retrospective cohort study at the neurocritical care unit of the University of Erlangen-Nuremberg (2016-2018) included 23 nontraumatic supratentorial (intracerebral hemorrhage) ICH patients without signs of abnormal pupillary function by manual assessment, i.e., absent light reflex. We assessed ICP levels by an external ventricular drain simultaneously with parameters of pupillary reactivity [i.e., maximum and minimum apertures, light reflex latency (Lat), constriction and redilation velocities (CV, DV), and percentage change of apertures (per-change)] using a portable pupillometer (NeurOptics®). Computed tomography (CT) scans were analyzed to determine lesion location, size, intraventricular hemorrhage, hydrocephalus, midline shift, and compression or absence of the basal cisterns.
