ABSTRACT
PURPOSE: The objective of this study was to assess the microleakage and flexural strength of glass ionomer cement (GIC) and modified GIC (Zirconomer) when coated with protective coating agents such as COAT-IT and G-COAT plus.
METHODS: Sixty tooth specimens were grouped into two groups based on the type of restorations (GIC (n = 30) and Zirconomer (n = 30)). The samples were further divided into three subgroups (n = 10) based on the protective coating agent (Petroleum jelly, G-COAT Plus, or COAT IT) applied. This study evaluated the microleakage at the occlusal and cervical margins of class V restoration after being subjected to dye penetration and sectioning. Each specimen was viewed under a 40 × microscope and was given scores based on the depth of dye penetration. They were statistically analyzed using the Kruskal-Wallis test and compared within the groups using the Mann- Whitney Test. In addition, flexural strength was assessed using standardized cuboid (25 × 2 × 2 mm) specimens of restorative materials with and without protective coating agents. The mean flexural strength data of all the subgroups were statistically evaluated using a one-way analysis of variance (ANOVA) and compared within the subgroups using the student t test.
RESULTS: A statistically significant difference was found when occlusal margin microleakage scores were evaluated with G-COAT Plus demonstrating the lowest occlusal margin microleakage when applied over GIC restoration. The increasing order of occlusal margin microleakage scores is as follows: GIC with G-COAT Plus, Zirconomer with COAT-IT, GIC with COAT-IT, GIC, Zirconomer with G-COAT Plus, and Zirconomer. However, the cervical margin microleakage scores revealed no significant difference. While flexural strength was found to be highest for the GIC group coated with G-COAT Plus, it was observed that there was a significant improvement in the flexural strength of both GIC and Zirconomer when coated with either of the protective coating agents.
CONCLUSION: Within the limitations of this in vitro study, it was observed that the application of protective coating agents can significantly reduce the potential microleakage and improve the flexural strength of the restorative material especially when zirconia-reinforced GIC is the restorative material.

ABSTRACT
PURPOSE: Ultrasound-guided percutaneous renal biopsy (PRB) has been considered as a golden standard for CKD diagnosis and is employed to identify potential therapeutic targets since 1950s. Post-biopsy hemorrhage is the most common complication, while severe bleeding complication might cause nephrectomy or death. Therefore, how to reduce the occurrence of complications while ensuring the success of PRB is always a clinical research topic.
METHODS: This study retrospectively collected and established a renal biopsy database of each patient who underwent ultrasound-guided PRB at a tertiary teaching hospital from September 2017 to December 2020 through the Health Information System. All the data were statistically processed by SPSS software.
RESULTS: A total of 1146 patients underwent PRB for various reasons. The overall rate of post-biopsy hemorrhage was 37.70% (432/1146). Of those bleedings, minor bleeding after PRB was found in 337 (29.41%), middle bleeding 84 (7.33%), major bleeding 11 (0.96%). Besides that, there were 96 patients (8.38%) reported their discomfort symptoms. There was no death. Females were at significantly increased risk of hemorrhagic complication than males (OR = 2.017, CI = 1.531-2.658). While the risk for hemorrhagic complication significantly decreased as BMI and platelet before renal biopsy increased (OR = 0.956, CI = 0.924-0.989; OR = 0.998, CI = 0.996-1.000). As the APTT time prolonged, the risk for hemorrhagic complication significantly increased (OR = 1.072, CI = 1.023-1.123). Those patients whose albumin were higher, also had higher risk for hemorrhagic complication than other patients (OR = 1.020, CI = 1.000-1.041). Specifically, postoperative urination within 4 h increased the risk for hemorrhagic complication (OR = 1.741, CI = 1.176-2.576).
CONCLUSION: Our analysis finds that the incidence of post-biopsy bleeding complication is 37.70%, and its risk is associated with female, lower BMI, lower platelet before renal biopsy, prolonged APTT, higher albumin, and postoperative urination within 4 h. The findings highlighted the importance of perioperative management for renal biopsy, including adequate risk assessment, tailored careful observation after PRB. And medical staff should pay more attention to fluid management after ultrasound-guided PRB.

ABSTRACT
PURPOSE: The aim of this study was to evaluate the long-term functional and MRI results of 35 patients who underwent bicruciate ligament reconstruction combining an ACL autograft using the gracilis and semitendinosus tendons and double-bundle PCL reconstruction using the LARS artificial ligament.
METHODS: The outcomes were measured using the Lysholm score, the Tegner activity level scale and the International Knee Documentation Committee form (IKDC 2000). KT-1000 was used to assess the clinical anterior knee laxity. Radiographs and Magnetic Resonance Imaging (MRI) was used to evaluate osteoarthritis, the continuity and integrity of ACL autograft and LARS.
RESULTS: This retrospective study examined 35 patients who underwent single-stage bicruciate ligament reconstruction between May 2005 and January 2017 with a follow-up period ranging from 3 to 15 years (a mean of 7.5 years). The mean Lysholm score was 74, mean IKDC 2000 was 71. There was a statistically significant difference with a higher Lysholm score (78.9) in early versus delayed surgical intervention (p = 0.023). Using the Kellgren Lawrence osteoarthritis classification system, radiographic findings showed stage II or III in 83% of the sample population. The MRI results revealed a rupture rate of 22% of the anterior autografted ligament and 28% of the posterior LARS artificial ligament. However, there were no long-term artificial ligament-induced complications. There was no correlation between artificial ligament rupture and poor functional results (Lysholm < 65).
CONCLUSION: The results of this study with a mean follow-up of 7.5 years show satisfactory functional scores considering the initial trauma. It seems reasonable to propose early surgical treatment with double reconstruction of the cruciate ligaments within the first 21 days of the trauma. Post-traumatic osteoarthritis is inevitable in multi-ligament knee injuries despite anatomical reconstruction. The use of a LARS artificial ligament appears to be a valid alternative for PCL reconstruction in the context of multi-ligament injury and in the absence of sufficient autologous transplants.

ABSTRACT
OBJECTIVE: Current studies on the association between fecal incontinence (FI) and depression are very limited, and most of them are restricted to women or elderly patients. This study aims to evaluate in detail the association between FI and depression among US adults.
METHODS: 13,480 adults aged 20 years and older were selected from the National Health and Nutrition Examination Survey 2005-2010. Monthly loss of solid, liquid, or mucous stool was defined as FI. Clinical depression and depression severity were assessed by the validated Patient Health Questionnaide-9 (PHQ-9). Models of multivariate logistic regression were used to calculate adjusted odds ratios (ORs). A subgroup analysis was carried out to ensure that the results were stable.
RESULTS: After adjusting for covariates such as demographics, risk behaviors and associated comorbidities, the PHQ-9 score and clinical depression were both significantly associated with FI, with ORs and 95%CIs of 1.11 (1.10-1.13) and 3.01 (2.53-3.57). Depression of all severities was also significantly associated with FI. The ORs and 95%CIs of FI with mild depression, moderate depression, and moderately severe to severe depression were 2.29 (1.96-2.68), 3.44 (2.77-4.27) and 4.65 (3.61-6.00), respectively. Subgroup analyses showed no statistically significant interactions (P > 0.05).
CONCLUSIONS: In conclusion, FI significantly associated with depression of any severity. Like the elderly or female patients with FI, young and middle-aged or men with FI are also at high risk of depression and should also be the focus of depression screening and early intervention.

ABSTRACT
INTRODUCTION AND HYPOTHESIS: The optimal number of onabotulinumtoxinA injections for the treatment of refractory overactive bladder syndrome is unknown. Our primary objective was to determine whether 10-injections sites with 100 units of onabotulinumtoxinA each were associated with less pain than 20-injections sites.
METHODS: In a single-blinded randomized trial, 100 units of onabotulinumtoxinA was administered, either as 10 × 1 ml or as 20 × 0.5 ml injections following the instillation of 30 ml of bupivacaine and 5 ml of NaHCO3 solution for 15 min. The primary outcome was procedural pain, as measured on an 11-point Numerical Pain Rating Scale (NPRS) immediately following the procedure. A power calculation estimated that 16 subjects in each arm were needed to detect a mean difference of 1 with a standard deviation of 1, on the NPRS score between the two treatment groups, with α 0.05 and power 80%. To adjust for an estimated 20% dropout rate, the final sample size was planned for 20 patients per group.
RESULTS: From October 2020 to November 2022, a total of 56 patients were approached and 40 were enrolled and randomized to two groups (21 in the 10-injections group and 19 in 20-injections group). The difference in the median pain score between the group was not statistically significant (4 [1.5-5] for 10 injections vs 3 [1-4] for 20 injections, p=0.823).
CONCLUSION: Patients’ perception of pain, efficacy, and adverse events did not significantly differ between patients receiving 10 and those receiving 20 injections of 100 units of onabotulinumtoxinA.

ABSTRACT
OBJECTIVES: To compare the outcomes of bipolar Transurethral Enucleation Resection of the Prostate (TUERP) and simple retropubic prostatectomy in patients with prostate volumes larger than 80 cc.
PATIENTS AND METHODS: A prospective randomized study included all patients amenable to surgeries for benign prostate hyperplasia (BPH) with prostate size over 80 cc at a tertiary care hospital between January 2020 to February 2022. Bipolar TUERP and Retropubic open prostatectomy techniques were compared regarding patients’ demographics, intraoperative parameters, outcomes, and peri-operative complications.
RESULTS: Ninety patients were included in our study and randomly assigned to bipolar TUERP (Group 1 = 45 patients) and retropubic open prostatectomy (Group 2 = 45 patients). The TUERP group demonstrated significantly lower operative time (77 ± 11 minutes vs. 99 ± 14 minutes, p < 0.001), hemoglobin drop (median = 1.1 vs. 2.5, p < 0.001), and resected tissue weight (71 ± 6.6 cc vs. 84.5 ± 10.6 cc, p < 0.001). Postoperatively, the TUERP group demonstrated significantly lower catheter time (median = 2 vs. 7 days, p < 0.001) and less hospital stay. IPSS, Qmax, and patient satisfaction were better in the TUERP group within six months of surgery. We reported 90-day complications after TUERP in 13.3% of patients compared to 17.8% after retropubic prostatectomy, with a statistically insignificant difference. Urethral stricture predominated after TUERP, while blood transfusion dominated in retropubic prostatectomy.
CONCLUSIONS: The present study found that TUERP had equivalent efficacy and safety to open retropubic prostatectomy for patients with BPH and prostate volumes > 80 ml.

ABSTRACT
BACKGROUND: The opinions on the efficacy and safety of no anticoagulation versus regional citrate anticoagulation for continuous KRT (CKRT) were controversial in patients with severe liver failure with a higher bleeding risk. We performed a randomized controlled trial to assess no anticoagulation versus regional citrate anticoagulation for CKRT in these patients.
METHODS: Adult patients with liver failure with a higher bleeding risk who required CKRT were considered candidates. The included participants were randomized to receive regional citrate anticoagulation or no-anticoagulation CKRT. The primary end point was filter failure.
RESULTS: Of the included participants, 44 and 45 were randomized to receive regional citrate anticoagulation and no-anticoagulation CKRT, respectively. The no-anticoagulation group had a significantly higher filter failure rate (25 [56%] versus 12 [27%], P = 0.003), which was confirmed by cumulative incidence function analysis and sensitive analysis including only the first CKRT sessions. In the cumulative incidence function analysis, the cumulative filter failure rates at 24, 48, and 72 hours of the no-anticoagulation and regional citrate anticoagulation groups were 31%, 58%, and 76% and 11%, 23%, and 35%, respectively. Participants in the regional citrate anticoagulation group had significantly higher incidences of Ca2+tot/Ca2+ion >2.5 (7% versus 57%, P < 0.001), hypocalcemia (51% versus 82%, P = 0.002), and severe hypocalcemia (13% versus 77%, P < 0.001). However, most (73%) of the increased Ca2+tot/Ca2+ion ratios were normalized after the upregulation of the calcium substitution rate. In the regional citrate anticoagulation group, there was no significant additional increase in the systemic citrate concentration after 6 hours.
CONCLUSIONS: For patients with liver failure with a higher bleeding risk who required CKRT, regional citrate anticoagulation resulted in significantly longer filter lifespan than no anticoagulation. However, regional citrate anticoagulation in patients with liver failure was associated with a significantly higher risk of hypocalcemia, severe hypocalcemia, and Ca2+tot/Ca2+ion >2.5.

ABSTRACT
Identifying the interactions between T-cell receptor (TCRs) and human antigens is a crucial step in developing new vaccines, diagnostics, and immunotherapy. Current methods primarily focus on learning binding patterns from known TCR binding repertoires by using sequence information alone without considering the binding specificity of new antigens or exogenous peptides that have not appeared in the training set. Furthermore, the spatial structure of antigens plays a critical role in immune studies and immunotherapy, which should be addressed properly in the identification of interacting TCR-antigen pairs. In this study, we introduced a novel deep learning framework based on generative graph structures, GGNpTCR, for predicting interactions between TCR and peptides from sequence information. Results of real data analysis indicate that our model achieved excellent prediction for new antigens unseen in the training data set, making significant improvements compared to existing methods. We also applied the model to a large COVID-19 data set with no antigens in the training data set, and the improvement was also significant. Furthermore, through incorporation of additional supervised mechanisms, GGNpTCR demonstrated the ability to precisely forecast the locations of peptide-TCR interactions within 3D configurations. This enhancement substantially improved the model’s interpretability. In summary, based on the performance on multiple data sets, GGNpTCR has made significant progress in terms of performance, universality, and interpretability.

ABSTRACT
OBJECTIVE: Quantify the frequency and drivers of unreported coronavirus disease 2019 (COVID-19) symptoms among nursing home (NH) staff.
DESIGN: Confidential telephone survey.
SETTING: The study was conducted in 70 NHs in Orange County, California, December 2020-February 2022.
PARTICIPANTS: The study included 120 NH staff with COVID-19.
METHODS: We designed a 40-item telephone survey of NH staff to assess COVID-19 symptom reporting behavior and types of barriers [monetary, logistic, and emotional (fear or stigma)] and facilitators of symptom reporting using 5-point Likert scales. Summary statistics, reliability of survey constructs, and construct and discriminant validity were assessed.
RESULTS: Overall, 49% of surveys were completed during the 2020-2021 COVID-19 winter wave and 51% were completed during severe acute respiratory coronavirus virus 2 (SARS-CoV-2) δ (delta)/ (omicron) waves, with a relatively even distribution of certified nursing assistants, licensed vocational or registered nurses, and nonfrontline staff. Most COVID-19 cases (71%) were detected during mandated weekly NH surveillance testing and most staff (67%) had ≥1 symptom prior to their test. Only 34% of those with symptoms disclosed their symptom to a supervisor. Responses were consistent across 8 discrete survey constructs with Cronbach α > 0.70. In the first wave of the pandemic, fear and lack of knowledge were drivers of symptom reporting. In later waves, adequate staffing and sick days were drivers of symptom reporting. COVID-19 help lines and encouragement from supervisors facilitated symptom reporting and testing.
CONCLUSIONS: Mandatory COVID-19 testing for NH staff is key to identifying staff COVID-19 cases due to reluctance to speak up about existing symptoms. Active encouragement from supervisors to report symptoms and stay home when ill was a major driver of symptom reporting and resultant infection prevention and worker safety measures.
