Prospective study.

Palpitations are common and have a negative impact on women's quality of life. While evidence suggests that inflammatory mechanisms may play a role in the development of palpitations, no studies have evaluated for this association in patients with breast cancer who report palpitations prior to surgery. The purpose of this pilot study was to evaluate for associations between the occurrence of palpitations and single nucleotide polymorphisms (SNPs) in genes for pro- and anti-inflammatory cytokines, their receptors, and transcriptional regulators.

Approximately one in four total knee replacement patients develop persistent pain. Identification of those at higher risk could help inform optimal management.

Age is known to be the major risk factor for both pain sensation and sporadic Alzheimer's disease (sAD). Pain management in AD is a critical health condition. However, assessing pain in sAD patients is challenging. The intracerebroventricularly injected streptozotocin (icv-STZ) rat model of sAD has been brought to the fore as a hopefully suitable model that could mimic some features of sAD. However, the exact mechanism by which this agent may induce AD-like pathology is largely unknown. In some studies, analgesic drugs have been suggested as possible prevention of AD and icv-STZ-induced AD-like pathology. Therefore, this study used formalin and tail-flick tests to investigate whether different doses of icv-STZ injections could affect acute and inflammatory pain sensation and edema volume over time. Behavioral responses were observed at four testing time points (1, 2.5, 3.5, and 6 months postinjection). The results indicate that icv-STZ was able to significantly decrease the animals' formalin pain threshold in both a time- and dose-dependent manner. Formalin-induced acute and chronic pain scores of animals treated with streptozotocin 3 mg/kg (STZ3) increased dramatically 2.5 months after injection and persisted thereafter. The augmentation in pain score induced by streptozotocin 1 mg/kg (STZ1) was observed from 3.5 months after STZ injection. However, the effect of streptozotocin 0.5 mg/kg (STZ0.5) was NS until 6 months after injection. However, formalin-induced paw edema occurred with a longer delay and was not detectable in STZ0.5-treated animals. In addition, only STZ3-treated animals significantly reduced the thermal pain threshold of animals 6 months after injection. These observations indicate that icv-STZ can sensitize central and/or peripheral receptors to pain. The effect of STZ is dose- and time-dependent. AD-like pathology induced by icv-STZ could be partially activated via pain processing pathways. Therefore, anti-inflammatory agents could alleviate AD-like symptoms via pain treatments.

To compare the clinical effectiveness of sodium polynucleotide, classic hyaluronic acid, and crosslinked hyaluronic acid for the management of painful knee osteoarthritis.

In virtual reality, avatar embodiment can spur perceptions and behaviours related the avatars' characteristics. We tested whether embodying superhero-like avatars can change self-perceptions in people with chronic low back pain (CLBP).

To compare patient-reported experience between a Penn expander activated every other day vs twice daily.

To systematically review the effectiveness and safety of telemedicine combined with usual care (in-person visits) compared to usual care for the therapeutic management and follow-up assessment of neurologic diseases.

CC-90001 selectively inhibits c-Jun N-terminal kinase (JNK), a stress-activated protein implicated in fibrosis. In 3 phase 1 trials evaluating CC-90001 pharmacokinetics, pharmacodynamics, and safety, healthy adults (N = 184) received oral CC-90001 in a single dose (10-720 mg) or multiple doses (30-480 mg once daily for 7-18 days) or placebo. CC-90001 was rapidly absorbed (median time to maximum concentration, 1-4 hours) and eliminated with a mean terminal elimination half-life of 12-28 hours. Steady state was reached on day 5, with a mean accumulation ratio of 1.5- to 2-fold following daily dosing. Exposure was similar in fed versus fasted participants and in Japanese versus non-Japanese participants. CC-90001 demonstrated dose- and exposure-dependent inhibition of JNK as determined by histopathological analysis of c-Jun phosphorylation in ultraviolet-irradiated skin. The most common treatment-emergent adverse events were nausea and headache; all were mild or moderate in intensity. Based on exposure-response analysis using high-quality electrocardiogram data, no clinically relevant QT prolongation liability for CC-90001 was observed. Overall, single- and multiple-dose CC-90001 were generally safe and well tolerated at the tested doses and demonstrated JNK pathway engagement. These results support further clinical evaluation of CC-90001.

Esophageal motility disorder is one of the pathogenesis of gastroesophageal reflux disease (GERD). The clinical and functional relationship between the ineffective esophageal motility (IEM) and GERD have been found. PPI is a widely used drug of this diaease, but some patients have poor efficacy. The purpose of this study was to investigate the efficacy and possible mechanism of Transcutaneous Neuromodulation in these patients.
