Background And Objective: Statin-induced myopathy (SIM) has been partially attributed to deficiency of dolichol and coenzyme Q10 (CoQ10). We aimed to test the safety and efficacy of plant polyprenols in combination with CoQ10 for alleviation of SIM.
Materials And Methods: In an open-label, one-center prospective pilot study patients with SIM received conifer-tree needle polyprenols (4mg/day) and CoQ10 (100mg/day) for 8 weeks. Symptoms and safety were evaluated according to symptom severity score (0-10), creatine kinase (CK) levels, exercise test, dynamometry, complete blood count, clinical biochemistry and electrocardiography.
Results: Of the 14 patients, 11 completed the study per protocol. Two patients withdrew consent due to travels abroad, and it was discontinued for one patient with stage 3 chronic kidney disease due to asymptomatic elevations of liver enzymes at week 4. No safety parameters changed significantly in per protocol group. Non-significant increase of CK levels was observed (P=0.231). Muscle pain (n=10) and weakness (n=7) scores improved significantly (P<0.001 and P=0.018, respectively). Muscle pain completely disappeared in 2 patients, weakness resolved in 3 patients and cramps disappeared in two patients. Four patients assessed improvement strong enough to consider increase of statin dose. No changes were observed in exercise test or dynamometry.
Conclusions: Conifer-tree polyprenols in combination with CoQ10 may be generally safe in patients with SIM, but caution should be exercised in patients with glomerular filtration rate <60mL/min and routine monitoring of the liver enzymes and CK is advocated in all patients. The observed efficacy provides the rationale for a larger, double-blind controlled study with polyprenols.

Positive inotropic responses upon administration of milrinone, an inhibitor of the phosphodiesterase enzyme (PDE), involve a well-pronounced positive chronotropic effect. Here we tested whether milrinone evokes this chronotropic response solely by PDE inhibition or by a concerted action that involve additional pharmacological targets. Milrinone stimulated increases in heart rate were studied in right atrial preparations of guinea pig in the presence or absence of inhibitors of putative ancillary molecular pathways or ion channels: i.

Background: Peripheral nerve sheath tumors (PNSTs) encompass entities with different cellular differentiation and degrees of malignancy. Spatial heterogeneity complicates diagnosis and grading of PNSTs in some cases. In malignant PNST (MPNST) for example, single cell sequencing data has shown dissimilar differentiation states of tumor cells.

Background: The minimal clinically important difference (MCID) is an important threshold to consider when evaluating the meaningfulness of improvement following an intervention. The JoyPop app is an evidence-based smartphone app designed to improve resilience and emotion regulation. Information is needed regarding the JoyPop app's MCID among culturally diverse youth.

Objectives: Based on previous empirical research on financial stressors and resources and using a prevention science framework, this pilot study examined the effect and acceptability of a three-session older adult financial exploitation prevention intervention.
Methods: Forty-five older adults participated in the study. Each participant completed three 30- to 45-minute sessions.

Purpose: The aim of the study was to evaluate operative time and postoperative complications of 4 post-training specialized surgeons.
Methods: This was a pilot retrospective chart review to determine the learning curve of a Shouldice primary inguinal hernia repair (Shouldice Repair) of 4 post-training specialized surgeons, at the Shouldice Hospital. The first 300 Shouldice Repairs (early learning block) were compared to their 900-1,000 repairs as the primary operating surgeon (late learning block).
