Multicenter Study Comparative Study Pragmatic Clinical Trial
Comparative effectiveness of Chuna manual therapy versus conventional usual care for non-acute low back pain: a pilot randomized controlled trial.
Low back pain (LBP) is common, with a lifetime prevalence of 80%, and as such it places substantial social and economic burden on individuals and society. Chuna manual therapy (CMT) combines aspects of physiology, biodynamics of spine and joint motion, and basic theory of movement dynamics. This study aimed to test the comparative effectiveness and safety of CMT for non-acute LBP. ⋯ Our results suggest that CMT has comparative efficacy for non-acute LBP and is generally safe. As this was a preliminary study, a well-powered (over 192 participants) two-arm (CMT versus UC) verification trial will be performed to assess the generalizability of these results.

Pain after major head and neck cancer surgery is underestimated and has both nociceptive and neuropathic characteristics. Extended resection, flap coverage, nerve lesions, inflammation, and high-dose opioid administration can also lead to hyperalgesia and chronic postoperative pain. Opioids are frequently associated with adverse events such as dizziness, drowsiness, nausea and vomiting, or constipation disturbing postoperative recovery and extending the length of hospital stay. Patients eligible for major head and neck cancer surgery cannot benefit from full multimodal pain management with locoregional anesthesia. Intravenous lidocaine, investigated in several studies, has been found to decrease acute pain and morphine consumption. Some data suggest also that it can prevent chronic postsurgical pain. Evidence supporting its use varies between surgical procedures, and there is no published study regarding systemic lidocaine administration in major head and neck cancer surgery. We hypothesized that intravenous lidocaine infused in the perioperative period would lead to opioid sparing and chronic postsurgical pain reduction. ⋯ Recent evidence suggests that intravenous lidocaine can lead to opioid sparing and chronic postsurgical pain reduction for certain types of surgery. This is the first trial to prospectively investigate the efficacy and safety of intravenous lidocaine in major head and neck cancer surgery.

Protective ventilation with high versus low positive end-expiratory pressure during one-lung ventilation for thoracic surgery (PROTHOR): study protocol for a randomized controlled trial.
Postoperative pulmonary complications (PPC) may result in longer duration of in-hospital stay and even mortality. Both thoracic surgery and intraoperative mechanical ventilation settings add considerably to the risk of PPC. It is unclear if one-lung ventilation (OLV) for thoracic surgery with a strategy of intraoperative high positive end-expiratory pressure (PEEP) and recruitment maneuvers (RM) reduces PPC, compared to low PEEP without RM. ⋯ PROTHOR is the first randomized controlled trial in patients undergoing thoracic surgery with OLV that is adequately powered to compare the effects of intraoperative high PEEP with RM versus low PEEP without RM on PPC. The results of the PROTHOR trial will support anesthesiologists in their decision to set intraoperative PEEP during protective ventilation for OLV in thoracic surgery.

Multicenter Study Comparative Study
Chemoradiation versus oesophagectomy for locally advanced oesophageal cancer in Chinese patients: study protocol for a randomised controlled trial.
Surgery is the gold standard treatment for local advanced disease, while definitive concurrent chemoradiotherapy (DCRT) is recommended for those who are medically unable to tolerate major surgery or medically fit patients who decline surgery. The primary aim of this trial is to compare the outcomes in Chinese patients with oesophageal squamous cell cancer with locally advanced resectable disease who have received either surgery or DCRT. ⋯ The preponderant oesophageal cancer pathology type is dramatically different in western Caucasian and Asian oesophageal cancer patients: Caucasian patients present with 80% adenocarcinomas, and Asians patients present with 95% squamous cell carcinomas. This phenomenon needs more in-depth studies to elucidate the differences in these populations. Based on the results of this study, we will show whether DCRT will benefit patients more than oesophagectomy. This study will contribute more evidence to the management of oesophageal squamous cell cancer.

Temporomandibular disorder (TMD) is the most common cause of orofacial and cervical skull pain and is considered to be a public health problem, affecting 5% to 12% of the world population. TMD is multifactorial and there are several types of treatment, with the conservative types being indicated more often as they are less aggressive and reversible. The main aim of these treatments is to relieve symptoms, reduce of pain, and restore orofacial and cervical skull functions. Photobiomodulation therapy (PBMT), a noninvasive therapy, is an option for the management of musculoskeletal disorders due to its analgesic, anti-inflammatory, and regenerative effects. ⋯ This study will verify whether PBMT is effective in reducing TMD and orofacial and cervical skull pain. PBMT may be an option for the management of musculoskeletal disorders due to its analgesic, anti-inflammatory, and regenerative effects, in addition to being a noninvasive technique.
