Practice Advisory for Preoperative and Intraoperative Pain Management of Cardiac Surgical Patients: Part 2.
Pain after cardiac surgery is of moderate to severe intensity, which increases postoperative distress and health care costs, and affects functional recovery. Opioids have been central agents in treating pain after cardiac surgery for decades. The use of multimodal analgesic strategies can promote effective postoperative pain control and help mitigate opioid exposure. ⋯ This Practice Advisory provides recommendations for providers caring for patients undergoing cardiac surgery. This entails developing customized pain management strategies for patients, including preoperative patient evaluation, pain management, and opioid use-focused education as well as perioperative use of multimodal analgesics and regional techniques for various cardiac surgical procedures. The literature related to this field is emerging, and future studies will provide additional guidance on ways to improve clinically meaningful patient outcomes.

Treatment of cervical dystonia with Botox (onabotulinumtoxinA): Development, insights, and impact.
Cervical dystonia (CD), the most common focal dystonia encountered in neurologic practice, is a chronic disorder in which the muscles of the neck involuntarily contract and cause abnormal postures and movements of the head, neck, and shoulders. Treatment of CD prior to botulinum toxin was unsatisfactory, as existing therapies often did not improve symptoms. The use of botulinum toxin for CD grew out of its success in treating blepharospasm, another type of focal dystonia. ⋯ In addition, onabotulinumtoxinA treatment also reduced the complications of CD, as patients no longer develop contractures (permanent muscle and tendon shortening from prolonged untreated dystonia), which markedly limited the range of neck motion. The onset of onabotulinumtoxinA treatment also accompanied advances in understanding the functional anatomy of neck muscles, basal ganglia physiology, and video and other recording technology. Following the success of onabotulinumtoxinA in the treatment of CD, its use has been expanded into numerous other therapeutic indications, and these advances stimulated educational and training programs by various neurologic and other medical societies.

Radiation is ubiquitous in nature, and radiation is also widely used in various fields of medicine, agriculture, and industry. Current biological doses below 100 mSv are called low-dose radiation (LDR). Scientists have no consensus of effects on humans below this dose, so a variety of dose-response curve theories have been derived. ⋯ Nuclear molecular imaging is LDR, using different radionuclides or combining with specific ligands (carries) to form "radiopharmaceuticals" for functional or pathological evaluations of diseases. As an integral part of patient care, nuclear medicine is used in the diagnosis, management, treatment, follow-up, and prevention of diseases. Therefore, this paper discusses literature review and provides appropriate scientific data and communication to help the peers and the public understand its advantage and disadvantage.

Both inflammation and oxidative stress contribute to the pathogenesis of sepsis and its associated organ damage. Angiotensin-(1-7), acting through the Mas receptor and angiotensin II-type 2 receptors (AT2R), could attenuate organ dysfunction and improve survival in rats with sepsis. However, the role of AT2R in inflammation and oxidative stress in rats with sepsis is unclear. Therefore, this study examined the modulatory effects and molecular mechanism of AT2R stimulation in rats with polymicrobial sepsis. ⋯ The protective effects of CGP42112 may be related to anti-inflammatory responses, suggesting that the stimulation of AT2R is a promising therapeutic candidate for the treatment of sepsis.

Psychological and neurological predictors of acupuncture effect in chronic pain patients: a randomized controlled neuroimaging trial.
Chronic pain has been one of the leading causes of disability. Acupuncture is globally used in chronic pain management. However, the efficacy of acupuncture treatment varies across patients. ⋯ Furthermore, support vector machine models applied to the questionnaire and brain features could jointly predict acupuncture improvement with an accuracy of 81.48%. Besides, the correlations and models were not significant in the sham-acupuncture group. These results demonstrate the specific psychological, brain functional, and structural predictors of acupuncture improvement and may offer opportunities to aid clinical practices.
