To investigated the concept and clinical practice of patient-controlled analgesia (PCA) in the treatment of cancer pain. Doctors, nurses, pharmacists from the oncology department, pain department, or hospice department were investigated using an electronic questionnaire from December 1 to December 31, 2021. In addition to the basic information, there were 26 questions were collected, including the current situation of cancer pain treatment, the concept of medical staff on PCA treatment of cancer pain and the clinical practice of PCA. Questionnaires from 2 872 medical staff were collected from 993 hospitals in 30 provincial administrative units. Only 34.8% (955/2 748) of medical staff considered that the satisfaction rate of cancer pain control was over 75%, and 27.9% (548/1 968) of medical staff convinced that the satisfaction rate of breakthrough pain control was less than 50%. 97.1% (2 439/2 513) of medical staff considered that PCA could be effectively used for cancer pain treatment. The proportion of medical staff in secondary and tertiary hospitals who thought that PCA was applicable to cancer pain that could not be effectively alleviated by standardized non-invasive drug administration was 64.6% (319/494) and 69.1% (1 262/1 826) respectively, which was higher than that in primary hospitals [57.0% (110/193)] (=0.002). In different occupations, the proportion of nurses who convinced PCA treatment of cancer pain increased the risk of addiction and drug overdose was 62.8% (431/686) and 76.1% (522/686), respectively, which was higher than doctors [39.2% (670/1709) and 58.2% (995/1709), respectively] and pharmacists [49.2% (58/118) and 65.3% (77/118), respectively] (all <0.001). There was no significant difference in type of pump, route of administration, mode of infusion, protocol for PCA administration and selection of common medication in PCA treatment of cancer pain among different hospitals (all >0.05). The calculation of continuous infusion dose and rescue dose of PCA was not uniform among different hospitals. After initiation of PCA, 71.7% (1 226/1 709) of hospitals had insufficient analgesia and most of them needed to be adjusted for 1-3 times to achieve satisfactory analgesia. Medical staff have insufficient cognition of PCA treatment of cancer pain and there is a lack of unified guidance in clinical practice. Therefore, it is an urgent need to develop an expert consensus on PCA treatment of cancer pain.

Retinopathy of prematurity (ROP) remains among the leading causes of childhood blindness. It affects mainly premature infants who tend to be systematically and clinically unstable and are more prone to complications and anesthesia related adverse effects when undergoing examination or treatment. A better comprehension of different analgesic and anesthetic methods used during screening and treatment may help in choosing a suitable option for ROP screening and treatment. An electronic search was done using MEDLINE, PubMed, and Embase databases. Search terms used included ROP, ROP, ROP screening, ROP treatment, analgesia, and anesthesia. All randomized clinical trials, large case series, and surveys were included in the review. Topical proparacaine is the most commonly used anesthesia during ROP screening and may significantly ease pain during ROP screening. Different comfort measures during screening may help infants recover faster but do not abolish pain. Topical tetracaine seems an effective pain-relieving option during intravitreal injections for ROP treatment. Photocoagulation of the peripheral retina under general anesthesia is considered the most common practice in the treatment of ROP. Further work is necessary to better understand the options of anesthesia methods offered for the treatment of ROP patients. This is a comprehensive review highlighting the available anesthetic methods for ROP patients to aid ophthalmologists in determining the most common and current anesthetic and analgesic practices.

Reports of local and systemic side-effects of COVID-19 vaccination may play an important role in public confidence in the acceptance of the COVID-19 vaccine booster dose.

We examined the neurological symptoms of patients treated in intensive care for COVID-19 in this study.

Pituitary apoplexy often manifests with a severe headache and is often caused by bleeding in a pituitary adenoma, which is common and often undiagnosed. The pituitary gland is damaged when the tumour suddenly enlarges due to bleeding. Bleeding into the pituitary can block blood supply to the pituitary gland. The larger the tumour, the higher the risk of a future pituitary apoplexy. Since only few cases have been reported, the SARS-CoV-2 vaccine is unlikely to cause pituitary apoplexy. Patients with new-type headache require neurological evaluation and may require cerebral imaging to rule out bleeding, ischemia, venous sinus thrombosis, meningitis, encephalitis, pituitary apoplexy, reversible cerebral vasoconstriction syndrome, dissection, or migraine.

Phantom limb pain (PLP) is a common type of chronic pain that occurs after limb amputation. Many treatment approaches are available, however, the treatment of PLP is still a challenge. This study aimed to quantify and rank the efficacy of interventions for phantom limb pain.

Nicotinamide adenine dinucleotide (NAD) is an omnipresent metabolite that participates in redox reactions. Multiple NAD-consuming enzymes are implicated in numerous biological processes, including transcription, signaling, and cell survival. Multiple pieces of evidence have demonstrated that NAD-consuming enzymes, including poly(ADP-ribose) polymerases (PARPs), sirtuins (SIRTs), and sterile alpha and TIR motif-containing 1 (SARM1), play major roles in peripheral neuropathic pain of various etiologies. These NAD consumers primarily participate in peripheral neuropathic pain via mechanisms such as mitochondrial dysfunction, oxidative stress, and inflammation. Furthermore, NAD synthase and nicotinamide phosphoribosyltransferase (NAMPT) have recently been found to contribute to the regulation of pain. Here, we review the evidence indicating the involvement of NAD metabolism in the pathological mechanisms of peripheral neuropathic pain. Advanced understanding of the molecular and cellular mechanisms associated with NAD in peripheral neuropathic pain will facilitate the development of novel treatment options for diverse types of peripheral neuropathic pain.

Previously we developed a murine model in which postinjury stimulation of an injured area triggers a transition to a nociplastic pain state manifesting as persistent mechanical hypersensitivity outside of the previously injured area. This hypersensitivity was maintained by sex-specific mechanisms; specifically, activated spinal microglia maintained the hypersensitivity only in males. Here we investigated whether spinal microglia drive the transition from acute injury-induced pain to nociplastic pain in males, and if so, how they are activated by normally innocuous stimulation after peripheral injury. Using intraplantar capsaicin injection as an acute peripheral injury and vibration of the injured paw as postinjury stimulation, we found that inhibition of spinal microglia prevents the vibration-induced transition to a nociplastic pain state. The transition was mediated by the ATP-P2X4 pathway, but not BDNF-TrkB signaling. Intrathecally injected GABA receptor agonists after intraplantar capsaicin injection prevented the vibration-induced transition to a nociplastic pain state. Conversely, in the absence of intraplantar capsaicin injection, intrathecally injected GABA receptor antagonists allowed the vibration stimulation of a normal paw to trigger the transition to a spinal microglia-mediated nociplastic pain state only in males. At the spinal level, TNF-α, IL-1β, and IL-6, but not prostaglandins, contributed to the maintenance of the nociplastic pain state in males. These results demonstrate that in males, the transition from acute injury-induced pain to nociplastic pain is driven by spinal microglia causing neuroinflammation and that peripheral injury-induced spinal GABAergic disinhibition is pivotal for normally innocuous stimulation to activate spinal microglia.

Children account for a substantial proportion of cases and deaths during Ebola virus disease outbreaks. We aimed to evaluate the safety and immunogenicity of a booster dose of the Ad26.ZEBOV vaccine in children who had been vaccinated with a two-dose regimen comprising Ad26.ZEBOV as dose one and MVA-BN-Filo as dose two.

Several infants endure substantial pain after hip operations, which can have a negative impact on their health by causing restlessness, depression, and sleep disruption. According to recent research, 20% of infants experience prolonged postsurgical pain 6 to 12 months following major surgery, which is linked to functional impairment and a lower quality of life.
