Dexmedetomidine (Dex), widely used as a sedative in surgical procedures and intensive care units, induces sympatholytic, anxiolytic, analgesic, and sedative effects. Postoperative cognitive dysfunction (POCD) is routinely observed in postoperative care following surgery and general anesthesia. The NLRP3 inflammasome complex plays a critical role in innate immune response by detecting pathogenic microorganisms and activating pro-inflammatory cytokines. Although there are numerous protective effects of Dex among the neurological diseases, specific mechanisms including NLRP3 inflammasome-mediated neuroinflammation via oxidative stress response in a POCD model are not fully understood. Here, we investigated whether Dex exhibits neurocognitive effects through the NLRP3 inflammasome signaling in a POCD mouse model using a neurobehavioral test and ELISA analysis. We also confirmed the level of oxidative stress-related response in the in vitro system in the POCD model. Furthermore, we evaluated the NLRP3 inflammasome complex by immunoprecipitation analysis. In summary, the results of the present study indicated that Dex showed a neuroprotective effect in the POCD model by reducing oxidative stress response through NLRP3 inflammasome-mediated neuroinflammation.

Psittacosis is an uncommon disease which mainly presents as community-acquired pneumonia (CAP). We aim to apply metagenomic next-generation sequencing (mNGS) as a promising tool in the diagnosis of psittacosis pneumonia and to describe its clinical spectrum to provide physicians with a better understanding and recognition of this disease. Thirteen cases of psittacosis pneumonia were diagnosed by using mNGS. A retrospective analysis of the data on clinical manifestations, laboratory data, computed tomography (CT) images, new diagnosis tools, treatments, and outcomes was summarized. These patients had common symptoms of fever and weakness; some had poor appetite, cough, myalgia, and headache. Ten patients developed acute respiratory distress syndrome (ARDS), among which six patients were severe pneumonia cases and needed ventilator therapy. Most patients got psittacosis pneumonia during the cold season. Ten cases were sporadic, but three were family clustering. All of the 13 patients were traced to an exposure history to birds, cat, or poultry, among which 2 only touched the innards of killed poultry before cooking, which may be an atypical exposure history not been reported before, to our knowledge. Most patients had various degrees of liver dysfunction. Air-space consolidations, along with ground-glass opacities and reticular shadows, were detected on chest CT scan. mNGS takes 48 to 72 h to provide results and helps to diagnose psittacosis. After being diagnosed by mNGS, with effective medicines, all patients finally had complete recoveries. The use of mNGS can improve the diagnostic rate of psittacosis pneumonia and shorten the course of disease control. Psittacosis pneumonia is easily underdiagnosed and misdiagnosed. In this study, we use mNGS in the diagnosis of psittacosis pneumonia. We found this disease is prone in the cold season, and touching the innards of killed poultry during cooking may be an atypical exposure history which has not been reported before to our knowledge. There are sporadic cases and family outbreak cases as well. Except for typical symptoms of fever and weakness, headache may be the main and only symptom in some patients. The rate of severe pneumonia is high among inpatients with psittacosis pneumonia, and the incidence of hepatic involvements is also high. Psittacosis pneumonia can be cured if the diagnosis is accurate and in time, even if it is severe pneumonia on admission. Some problems worthy of our attention about psittacosis pneumonia were put forward, such as its sick season, special exposure history, the rate of severe disease, and the high cure rate. mNGS can quickly and objectively detect more rare pathogenic microorganisms in clinical specimens without the need for specific amplification and has an advantage in the diagnosis of rare pathogenic bacteria in difficult cases such as psittacosis pneumonia. The use of mNGS can improve the accuracy and reduce the delay in the diagnosis of psittacosis, which shortens the course of disease control.

Real-world data on transitioning to Immune Globulin Subcutaneous (Human) 20% solution (Ig20Gly) are limited. This study aimed to assess infusion parameters and experience of patients with primary (PID) or secondary immunodeficiencies (SID) transitioning to Ig20Gly in clinical practice in Canada.

To understand perioperative practices for transoral robotic surgery (TORS) among academic medical centers. An electronic cross-sectional survey was distributed to fellows and program directors participating in 49 American Head and Neck Society fellowships. Operative decisions, medical and swallowing management, and disposition planning were assessed. Thirty-eight responses were collected (77.6%). Twenty-three centers (60.5%) performed > 25 cases annually with the remainder performing fewer. The da Vinci Si was the most commonly used platform (n = 28, 73.7%). A majority of institutions advocated tailored resection to adequate margins (n = 27, 71.1%) over fixed subunit-based resection (n = 11, 28.9%). Most surgeons (n = 29, 76.3%) performed neck dissection concurrent with TORS, and 89.5% (n = 34) routinely ligated external carotid artery branches. A minority of institutions (n = 17, 45.9%) endorsed a standardized TORS care pathway. Antibiotic choices and duration varied, the most common choice being ampicillin/sulbactam (n = 21, 55.3%), and the most common duration being 24 h or less (n = 22, 57.9%). Multimodal analgesia was used at 36 centers (94.7%), steroids at 31 centers (81.6%), and pharmacologic venous thromboembolic prophylaxis at 29 centers (76.3%). Nasogastric feeding tubes were placed during surgery at 20 institutions (54.1%). Speech-language pathologists routinely performed postoperative swallow evaluations at 29 (78.4%) sites. Practice patterns are variable among institutions performing TORS. While certain surgical and postoperative practices were quite common, many institutions reported no standard TORS care pathway. Further understanding of the impact of individual practices on outcomes is necessary to develop evidence-based perioperative protocols for TORS.

BACKGROUND The blind-ending branch of a bifid ureter is a rare congenital anomaly which is usually asymptomatic but can occasionally give rise to various symptoms, such as chronic abdominal pain. Diagnosis is most often confirmed radiologically, and treatment is usually conservative. Surgical resection of the blind ending of a bifid ureter should be considered in cases of persistent symptoms. CASE REPORT A female patient of 49 years of age presented with intermittent right lumbar pain, repetitive urinary infections and microscopic hematuria. We present here the diagnostic work-up of the case, leading to the identification of the existence of ureteral bifidity located at the lower third of the ureter and of a blind ending of the bifid ureter. Several regimens of various antibiotics failed to resolve the symptoms. It was decided to carry out a laparoscopic resection of the blind ending of the bifid ureter. We describe the practical procedures of the surgical operation and discuss briefly the embryological etiology and the physiopathology of the condition as well as the principal diagnostic modalities. Since the surgery, the patient has been symptom-free. CONCLUSIONS Despite being usually asymptomatic, the rare congenital anomaly of a bifid ureter with a blind ending can occasionally give rise to symptoms such as recurrent infections and persistent abdominal pain. Laparoscopic-based resection of the blind ending should be considered in such cases.

Multiple clinical trials showed that 12 weeks of abrocitinib monotherapy was safe and effective for the treatment of moderate-to-severe atopic dermatitis (AD). The reversibility of pharmacologic activity after abrocitinib discontinuation was not described.

To summarize the experience of endoscopic endonasal approach in the treatment of anterior skull base with intra-extracranial extension meningioma, and to analyze the perioperative quality of life of patients, and to discuss the safety and efficacy of the treatment. A total of 83 cases of anterior skull base with intra-extracranial extension meningioma admitted to Xuanwu Hospital, Capital Medical University from October 2007 to October 2019, who underwent endoscopic endonasal approach tumor resection, were retrospectively analyzed. The quality of life of the patients were evaluated by Anterior Skull Base Questionnaire (ASBQ) before and after surgery. The surgical techniques, extent of tumor resection, postoperative complications and the changes of patients' quality of life were summarized and analyzed. SPSS 23.0 software was used for statistical analysis. A total of 57 anterior skull base with intra-extracranial extension meningioma patients were enrolled according to the inclusion and exclusion criteria, including 23 males and 34 females, aging (48.6±16.6) years. Fifty cases (87.7%) reached or exceeded Simpson gradeⅠ resection, and 7 cases underwent subtotal resection. Symptoms relief was as follows: headache relief in 45/50 (90%), vision improvement in 18/19 (94.7%), olfaction improvement in 6/45 (13.3%), mental symptoms improvement in 3/9 (33.3%), and seizure relief in 5/7 (71.4%). Postoperative complication included mental symptoms in 5 cases, cerebrospinal fluid leakage in 2 cases, epilepsy in 2 cases, frontal lobe hemorrhage in 1 case, and intracranial infection in 1 case. The follow-up period was 38 to 144 months. There were two cases recurring and no death. ASBQ assessment showed significant improvement in general condition, physical function, role function, mood disorder, pain, vision impairment, and sleep disturbance at 1 month postoperatively, with continued improvement thereafter, and reached stable at 6 months postoperatively. Endoscopic endonasal approach surgery is able to achieve safe and effective tumor resection for anterior skull base intra-extracranial extension meningioma, and the quality of life of patients can be improved steadily.

The COVID-19 pandemic could be a threat for the health status of children with a chronic condition. The present study aimed to explore parents' and children's psychological adjustment during the current pandemic, pursuing a triple objective: to compare the psychological adjustment of parents of children with pediatric rheumatic diseases (PRDs) and parents of healthy children; to analyze children's psychological symptoms (emotional problems and hyperactivity) before and during the COVID-19 pandemic, and with or without a PRDs diagnosis; to explore the associations of children's emotional problems and hyperactivity with parents' psychological adjustment, parent-child interactions and belonging or not to families with PRDs. This cross-sectional study involved 56 parents of children with PRDs and 53 parents of healthy children. Self-report questionnaires about parents' depression, anxiety, parenting stress, and children's emotional symptoms and hyperactivity-inattention were administered. No differences were detected on psychological adjustment between parents of children with PRDs and parents of healthy children. Parents of children with PRDs reported statistically significant higher levels of children's emotional problems and hyperactivity before the pandemic, compared to parents of healthy children; during COVID-19 pandemic, emotional symptoms increased for both groups, while hyperactivity-inattention symptoms increased only in the group of healthy children. Children's emotional difficulties were associated with higher levels of parental anxiety, worse parent-child interaction and having PRDs; children's hyperactivity symptoms were related to parent-child difficult interaction and higher levels of parental depression. Findings suggest the importance to target the children in relation to their parents, when approaching the psychological aspects of PRDs.

As an innovative exercise therapy, therapeutic climbing (TC) has attracted more attention than ever before in recent years. In this review of the related studies on TC, the authors explore its origin and development; summarize its therapeutic effect in treating depression, low back pain and other diseases; and further analyze its underlying mechanism. According to the literature, TC was primarily applied in the field of orthopedics and then was gradually used in neurology, psychiatry and psychology. It provides a new means for the treatment of depression, lower back pain, multiple sclerosis and other diseases. There are two potential mechanisms: physiological and psychological. In the future, exercise effects, adverse effects and exercise prescriptions of TC should be explored with large samples and high-quality randomized controlled trials.
