The mu-opioid receptor (MOR) is a major target for the treatment of pain. However, opioids are prone to side effects which limit their effectiveness as analgesics and can lead to opioid use disorders or, even, lethal overdose. The systemic administration of opioid agonists makes it both very difficult to decipher their underlying circuit mechanisms of action and to limit drug action to specific receptor subpopulations to isolate therapeutic effects from adverse side effects.

Therefore, we first studied the link between sleep disturbances and the activation of nociceptors in two acute pain models. Activation of nociceptors in both acute inflammatory (AIP) and opto-pain models led to sleep loss, decreased sleep spindle density, and increased sleep fragmentation that lasted 3 to 6 hours.

Objective: The present study aimed to compare time to effective pain relief between diclofenac 75 mg intramuscular (IM) and tramadol 50 mg intravenous (IV) for ED patients with acute renal colic.
Methods: A randomised, double-blinded, sham-controlled, superiority trial was conducted. Patients diagnosed with acute renal colic (hydronephrosis and/or stone visualisation on point-of-care ultrasound) in the ED were randomly assigned to receive an IM injection of 75 mg of diclofenac or IV tramadol 50 mg.

Aim: Natural orifice specimen extraction surgery (NOSES) has gained significant importance in treating cancers. The current study is a meta-analysis that aimed to assess the short-term efficacy and long-term prognostic impact of NOSES and conventional laparoscopic (CL) surgery in the treatment of colorectal cancer (CRC).
Method: Published reports in several medical databases up to February 2024 were searched and information pertinent to outcomes of NOSES and CL in retrospective and randomized studies to treat CRC was collected.
