Background:
This study aimed to assess the severity of postoperative delirium (PD) in elderly patients who underwent reverse total shoulder arthroplasty (rTSA) for irreparable massive rotator cuff tears (mRCTs) under general anesthesia (GA) compared to those under interscalene block (IB).
Methods:
Forty elderly patients aged 65 years or older diagnosed with an irreparable mRCT who underwent rTSA were included in the prospective case-controlled study. Of these, 20 patients were operated under GA and the other 20 under IB. The average age was 77.1 years (range, 65–95 years). The severity of delirious symptoms was evaluated by the Delirium Rating Scale–revised–98 (DRS) score from the patients or guardians before the surgery and at 0, 3, and 7 days and 1, 3, and 6 months after the surgery and compared between the 2 groups.
Results:
Immediately after surgery, the visual analog scale score difference between the groups was statistically significant, with the GA group at 6.25 (standard deviation, ± 0.85) and the IB group at 3.80 (± 0.62) (p < 0.001). On the day of operation, the mean DRS score in the GA and IB groups were 9.10 (± 5.63) and 6.60 (± 5.33), respectively (p = 0.157). On day 3 of surgery, the mean DRS score in the GA group peaked to 9.95 (± 8.73), while in the IB group, it declined to 6.40 (±5.81) (p = 0.138). After 3 days, DRS scores showed a decreasing trend in both groups. When comparing the mean change (∆) from the preoperative baseline scores to the postoperative values, the ∆DRS score was significantly higher with 4.15 (± 4.53) points in the GA group as compared to 1.30 (± 1.92) in the IB group (p = 0.014).
Conclusions
IB can be an attractive and efficient anesthetic choice in preventing PD for elderly patients undergoing rTSA for irreparable mRCTs. The IB group showed lower DRS scores and a peak on day 0 compared to the higher DRS scores and peak on day 3 in the GA group. Additionally, IB showed less pain than GA.

To restore masticatory function, dental implants require adequate bone support. For extensive maxillary bone loss, sinus lift surgery with bone grafting is often employed, favoring the autogenous iliac crest bone for better implant integration. Guides aid in the precise placement of implants and can reduce surgery time. In this context, an approach that combines of sinus lifting, bone grafting, and implant placement can be beneficial. In April 2020, a 58-year-old male presented with severe left maxillary alveolar bone atrophy and peri-implantitis of the right maxilla. Implants #15i, # 16i, and # 17i were removed, followed by bilateral sinus lift, bone grafting, and implant placement. During the 2-year follow-up after prosthesis placement, both the graft material and implants remained stable without complications. Iliac bone grafts exhibit greater resorption than other graft materials. In this case, implant positioning based on virtual planning and modifications guided by experience was performed without complications.

Despite the various medications used in clinics, the efforts to develop more effective treatments for depression continue to increase in the past decades mainly because of the treatment-resistant population, and the testing of several hypotheses- and target-based treatments. Undesirable side effects and unresponsiveness to current medications fuel the drive to solve this top global health problem. In this study, we focused on neuroinflammatory response-mediated depression which represents a cluster of depression etiology both in animal models and humans. Several meta-analyses reported that proinflammatory cytokines such as interleukin 6 (IL-6) and tumor necrosis factor-α (TNF-α) were increased in major depressive disorder patients. Inflammatory mediators implicated in depression include type-I interferon and inflammasome pathways. To elucidate the molecular mechanisms of neuroinflammatory cascades underlying the pathophysiology of depression, we introduced hycanthone, an antischistosomal drug, to check whether it can counteract depressive-like behaviors in vivo and normalize the inflammation-induced changes in vitro. Lipopolysaccharide (LPS) treatment increased proinflammatory cytokine expression in the murine microglial cells as well as the stimulation of type I interferon-related pathways that are directly or indirectly regulated by Janus kinase-signal transducer and activator of transcription (JAK-STAT) activation. Hycanthone treatment attenuated those changes possibly by inhibiting the JAK-STAT pathway and inflammasome activation. Hycanthone also ameliorated depressive-like behaviors by LPS. Taken together, we suggest that the inhibitory action of hycanthone against the interferon pathway leading to attenuation of depressive-like behaviors can be a novel therapeutic mechanism for treating depression.

Background:
Information on the effectiveness of nirmatrelvir/ritonavir against the omicron is limited. The clinical response and viral kinetics to therapy in the real world need to be evaluated.
Methods:
Mild to moderate coronavirus disease 2019 (COVID-19) patients with risk factors for severe illness were prospectively enrolled as a treatment group with nirmatrelvir/ritonavir therapy versus a control group with supportive care. Serial viral load and culture from the upper respiratory tract were evaluated for seven days, and clinical responses and adverse reactions were evaluated for 28 days.
Results:
A total of 51 patients were analyzed including 40 in the treatment group and 11 in the control group. Faster symptom resolution during hospitalization (P= 0.048) was observed in the treatment group. Only minor adverse reactions were reported in 27.5% of patients. The viral load on Day 7 was lower in the treatment group (P = 0.002). The viral culture showed a positivity of 67.6% (25/37) vs. 100% (6/6) on Day 1, 0% (0/37) vs. 16.7 (1/6) on Day 5, and 0% (0/16) vs. 50.0% (2/4) on Day 7 in the treatment and control groups, respectively.
Conclusions
Nirmatrelvir/ritonavir against the omicron was safe and resulted in negative viral culture conversion after Day 5 of treatment with better symptomatic resolution.
