    Cranioplasty is a standard procedure used to restore skull defects after craniectomy. Many different materials are used in cranioplasty. The study aim was to compare the surgical outcomes of cranioplasty using different materials liquid polymethylmethacrylate (PMMA), customized PMMA, and titanium. The authors retrospectively reviewed the outcomes of cranioplasty performed from 2016 to 2021. Data collection included patient characteristics and complications, including postoperative infection, hematoma, implant exposure, and subgaleal cerebrospinal fluid collection. Eighty-five patients received cranioplasty with different materials titanium, 14; customized PMMA, 31; and liquid PMMA, 40. There were no significant differences in the basic patient characteristics among the 3 cranioplasty groups except for lower age in the customized PMMA group. There were no significant differences between superficial and deep infections, implant exposure, postoperative hematoma, or seizure. this website However, subgaleal cerebrospinal flug the 3 cranioplasty groups except for lower age in the customized PMMA group. There were no significant differences between superficial and deep infections, implant exposure, postoperative hematoma, or seizure. However, subgaleal cerebrospinal fluid collection was more common in the liquid PMMA group than in the customized PMMA group ( P = 0.02). This study showed that good outcomes were achieved by cranioplasty performed with different materials (titanium, customized PMMA, and liquid PMMA).

    Combined orbital medial wall and floor fractures and large isolated orbital floor fractures commonly require surgical treatment due to the high probability of diplopia and enophthal-mos. Primary reconstruction of these orbital fractures requires a high-level surgeon with a great amount of technical surgical skill. The use of novel technology can greatly improve the accuracy of reconstruction and achieve satisfactory clinical outcomes. Hence, the authors aimed to present our findings and overall experience with respect to extensive floor and medial wall orbital fracture reconstruction according to the Computerized Operation Neuronavigated Surgery Orbital Recent Trauma (CONSORT) protocol, a workflow designed for the primary reconstruction of orbital fractures with customized mesh and intraoperative navigation. A total of 25 consecutively presenting patients presenting with unilateral extensive orbital floor fractures and orbital floor and medial wall fractures were treated following the CONSORT workflow from jury. Preopera-tive and postoperative functional and aesthetic outcomes are described herein. All fractures were successfully reconstructed. Postoperatively, all 19 patients with preoperative diplopia reported the resolution of diplopia. Enophthalmos resolved in 18/20 cases. No patients had major complications during follow-up. Thus, the authors conclude that the CONSORT protocol introduced by the authors is an adaptable and reliable workflow for the early treatment of orbital fractures and can clearly optimize functional and aesthetic outcomes, reduce costs and intensive time commitments, and make customized and navigated surgery more available for institutions.

    Orthognathic occlusal repositioning wafers could be constructed virtually and 3D printed. This paper assessed the accuracy of a suggested virtual model to the conventionally established Glasgow model surgery.

    Prospective study of the orthognathic surgery models digitally.

    Seven patients who received bi-maxillary orthognathic surgeries for correction of dentofacial deformities.

    The patients were clinically assessed and their cone beam cmputerized tomography (CBCT) studied. link2 Model surgery of each patient was performed conventionally using face-bow and semi-adjustable articulator. Same plan was executed virtually using Mimics (Materialise, Leuven, Belgium) and 3Matic (Materialise, Leuven, Belgium). Conventionally fabricated acrylic wafers as well as 3D printed wafers were CBCT scanned with the casts reflecting the archived repositioning dictated by the wafers. Paired sample t test was performed to compare accuracy between intermediate and final occlusal repositioning wafers within conventional and virtual technique groups.

    The mean deviation in intermediate wafer group was 0.64 ± 0.33 mm; whereas the mean deviation in final wafer group was 0.53 ± 0.10 mm. Paired sample t test showed that there was no statistically significant difference in mean deviation between both groups ( P = 0.403).

    This virtual surgical wafer achieves a similar level of accuracy to the conventional Glasgow model surgery.

    Endoscopic resection bleeding (ERB) classification was proposed by the authors’ team to evaluate the severity of intraoperative bleeding (IB) during endoscopic submucosal dissection (ESD). This study aimed to evaluate the application of ERB classification and to analyze the risk factors of major IB (MIB) and postoperative bleeding (PB) associated with ESD for gastric neoplastic lesions.

    We retrospectively enrolled a total of 1334 patients who underwent ESD between November 2006 and September 2019 at The First Medical Center of Chinese People’s Liberation Army General Hospital. All patients were divided into the non-MIB group (including ERB-0, ERB-controlled 1 [ERB-c1], and ERB-c2) and the MIB group (including ERB-c3 and ERB-uncontrolled [ERB-unc]) according to the ERB classification. Risk factors of major MIB and risk factors of PB were analyzed using a logistic regression model.

    Among the 1334 patients, 773 (57.95%) had ERB-0, 477 (35.76%) had ERB-c1, 77 (5.77%) had ERB-c2, 7 (0.52%) had ERB-c3, and no patients had ERB-unc. The rate of PB in patients with IB classifications of ERB-0, ERB-c1, ERB-c2, and ERB-c3 were 2.20% (17/773), 3.35% (16/477), 9.09% (7/77), and 2/7, respectively. In multivariate analysis, proximal location (odds ratio [OR] 1.488; 95% confidence interval [CI] 1.045-3.645; P = 0.047) was the only significant risk factor of MIB. Chronic kidney disease (CKD) (OR 7.844; 95% CI 1.637-37.583; P = 0.010) and MIB (ERB-c3) (OR 13.932; 95% CI 2.585-74.794; P = 0.002) were independent risk factors of PB.

    Proximal location of lesions was a significant risk factor of MIB. Additionally, CKD and MIB (ERB-c3) were independent risk factors of PB. More attention should be paid to these high-risk patients for MIB and PB.

    The first-line treatment for lung cancer is surgical resection, and one-lung ventilation (OLV) is the most basic anesthetic management method in lung surgery. During OLV, inflammatory cytokines are released in response to the lung tissue damage and promote local and contralateral lung damage through the systemic circulation. We designed a randomized, prospective study to evaluate the effect of the urinary trypsin inhibitor (UTI) ulinastatin on the inflammatory response after video-assisted thoracic lobectomy in patients with lung cancer.

    Adult patients aged 19 to 70 years, who were scheduled for video-assisted thoracic lobectomy surgery to treat lung cancer between May 2020 and August 2020, were enrolled in this randomized, prospective study. UTI (300,000 units) mixed with 100 mL of normal saline in the ulinastatin group and 100 mL of normal saline in the control group was administered over 1 h after inducing anesthesia.

    The baseline (T0) interferon-γ (IFN-γ)/interleukin-4 (IL-4) ratio was not different between the groups (6941.3 ± 2778.7 vs. 6954.3 ± 2752.4 pg/mL, respectively; P  > 0.05). The IFN-γ/IL-4 ratio was significantly higher in ulinastatin group at 30 min after entering the recovery room than control group (20,148.2 ± 5054.3 vs. 6674.0 ± 2963.6, respectively; adjusted P < 0.017).

    Administering UTI attenuated the anti-inflammatory response, in terms of INF-γ expression and the IFN-γ/IL-4 ratio, after video-assisted thoracic surgery in lung cancer patients.

    To determine the longitudinal relationships between abnormal glucose metabolism and physical function in persons with HIV (PWH) and without HIV.

    Prospective cohort study of men with or at risk for HIV in four United States cities between 2006 and 2018.

    Men with or at risk for HIV from the Multicenter AIDS Cohort Study (MACS) had semi-annual assessments of glycemic status, grip strength, and gait speed. We used linear mixed models with random intercept to assess associations between glycemic status and physical function. Glycemic status was categorized as normal, impaired fasting glucose (IFG), controlled diabetes mellitus [hemoglobin A1C (HbA1C) <7.5%], or uncontrolled diabetes mellitus (HbA1C ≥ 7.5%).

    Of 2240 men, 52% were PWH. Diabetes mellitus was similar among PWH (7.7%) vs. persons without HIV (6.7%, P = 0.36) at baseline. PWH had slower gait speed (1.17 vs. link3 1.20 m/s, P < 0.01) but similar grip strength (40.1 vs. 39.8 kg, P = 0.76) compared with persons without HIV at baseline. In multivariate models, gait speed decline was greater with controlled diabetes mellitus [-0.018 m/s (-0.032 to -0.005), P = 0.01] and grip strength decline was greater with controlled [-0.560 kg (-1.096 to -0.024), P = 0.04] and uncontrolled diabetes mellitus [-0.937 kg (-1.684 to -0.190), P = 0.01), regardless of HIV serostatus compared with normoglycemic individuals.

    Abnormal glucose metabolism was associated with declines in gait speed and grip strength regardless of HIV serostatus. These data suggest that improvement in glucose control should be investigated as an intervenable target to prevent progression of physical function limitations among PWH.

    To evaluate the safety and the serological response after two doses of mRNA-based SARS-CoV-2 vaccination in people with HIV (PWH).

    Participants were evaluated 4 weeks after the second dose of mRNA-1273 or BNT162b2 vaccine. Tolerability was evaluated with a specific adverse event questionnaire. Patient’s sera were analysed using LIAISON SARS-CoV-2 TrimericS IgG (DiaSorin).

    One-hundred PWH were included, 75% of them men, with a mean age of 44 ± 11 years old, all receiving antiretroviral treatment and mostly with controlled viral loads (98% with HIV RNA <50 copies/ml) and 96% had >200 CD4+/μl. All patients seroconverted after vaccination (antibody concentration ≥33.8 binding antibody units [BAU]/ml). Only 3% of the patients had a low antibody concentration (<520 BAU/ml), whereas 67% of them had concentrations above the assay’s detection range (>2080 BAU/ml). Fifty-six patients had local or systemic symptoms, with mild arthromyalgia being the most common systemic symptom. No severe adverse events were reported.
