Abstract
OBJECTIVES This study sought to identify the factors associated with the life satisfaction and peace of mind (PoM) of dentists not in full-time clinical training. MATERIALS AND METHODS Cross-sectional questionnaires were distributed to dentists in Taiwan to collect their life satisfaction, PoM, sociodemographic data, and dental career-related characteristics. Life satisfaction was measured using a 5-item Satisfaction with Life Scale. PoM was measured using a 7-item Peace of Mind Scale. Descriptive statistics and multiple linear regression models were estimated to explore potential associations between the two scales and the examined factors. RESULTS A total of 1196 dentists (45.6% female; mean age = 44.12) completed the questionnaires. The response rate of completed questionnaires from email invitations was 32.9%. On multivariable analysis, life satisfaction and PoM were associated with age (b = 0.008 in both), better perceived health (b = 0.262 and 0.308, respectively), family interaction (b = 0.264 and 0.207, respectively), and friend relationships (b = 0.076 and 0.091, respectively). Being married (b = 0.191), being specialized (b = 0.127), working in private practice, and spending 10 to 39 h per week with patients (b = 0.101 to 0.162) were associated with a higher level of life satisfaction but not PoM. CONCLUSIONS Specialists working in private practice without working overtime were associated with better life satisfaction. However, the dentists' health and relationships with family were more related to their subjective well-being than their professional achievements. CLINICAL RELEVANCE Our findings can help policymakers increase awareness of the well-being of general dentists and those in academia or hospitals to promote their mental health.

Abstract
OBJECTIVE This study aimed to investigate (1) the temporal pattern of ferroptosis, an iron-dependent cell death, in ligation-induced rat periodontitis and (2) the effect of ferrostatin-1, a ferroptosis inhibitor, on the model. BACKGROUND Ferroptosis may contribute to various diseases. However, the role of ferroptosis in periodontitis is still fully understood. METHODS In the first experiment, 25 rats with ligation-induced periodontitis were sacrificed on days 0, 1, 2, 7, and 10. Gingivae were obtained to determine tumor necrosis factor (TNF)-α, interleukin (IL)-1β, and ferroptotic biomarkers, including solute carrier family 3 member 2 (SLC3A2) and solute carrier family 7 member 11 (SLC7A11) and glutathione peroxidase 4 (Gpx4), via immunoblotting. Using microcomputed tomography (μCT) and histology, the periodontal soft and hard tissue lesions, including dental alveolar bone crest level, bony characteristics of the surrounding alveolus, periodontal tissue inflammation, and periodontal tissue losses, were evaluated. In study two, 16 rats with induced periodontitis were grouped according to ferrostatin-1 treatment. The rats were intraperitoneally injected with solvent or ferrostatin-1 (1.5 mg/kg/day) 1 day before ligation and sacrificed on days 7 and 10. Gingival protein changes and periodontal tissue damage were also examined. RESULTS In study one, SLC3A2/SLC7A11 and Gpx4 decreased since day 1; however, TNF-α/IL-1β increased on days 7 and 10. Moreover, the μCT/histology revealed resorptive bony characteristics, inflamed gingival tissue, and periodontal attachment loss. In study two, ferrostatin-1-injected rats exhibited significantly increased SLC3A2/SLC7A11 and Gpx4 but decreased TNF-α/IL-1β than vehicle rats. They also revealed lessened bone resorption, tissue inflammation, and attachment loss. CONCLUSION This study highlights the role of ferroptosis, via the system Xc/Gpx4 pathway, in experimental periodontitis and may serve as a regulatory strategy.

Abstract
Objective: This retrospective, single-center study aimed to evaluate the efficacy and safety of programmed death-1 (PD-1) inhibitors, either as monotherapy or in combination with chemotherapy, in the management of relapse/refractory classical Hodgkin's lymphoma (R/R cHL) . Methods: A total of 35 patients with R/R cHL who received treatment at the Institute of Hematology and Blood Diseases Hospital, Chinese Academy of Medical Sciences & Peking Union Medical College from September 2016 to December 2020 were enrolled in this study. Among them, 17 patients received PD-1 inhibitor monotherapy (PD-1 inhibitor group), while 18 patients received a combination of PD-1 inhibitor and chemotherapy (PD-1 inhibitor + chemotherapy group). Clinical data and follow-up information were retrospectively analyzed, and survival analysis was conducted using the Kaplan-Meier method and Cox proportional hazards model. Results: The median age of the 35 patients with R/R cHL was 29 years (range: 11-61 years), with 54.3% being male. According to the Ann Arbor staging system, 62.9% of patients presented with advanced (stage Ⅲ/Ⅳ) disease, and 48.6% had extranodal involvement. Before PD-1 inhibitor therapy, the median number of prior lines of therapy was 2 (range: 1-3). Objective responses were observed in 28 patients, including 22 complete response (CR) cases, resulting in an overall response rate (ORR) of 80.0% and a CR rate of 62.9%. Specifically, the ORR and CR rates were 64.7% and 58.8%, respectively, in the PD-1 inhibitor group and 94.4% and 66.7%, respectively, in the PD-1 inhibitor + chemotherapy group. Among the 18 patients who underwent sequential autologous hematopoietic stem cell transplantation (auto-HSCT) [13 CR and five partial response (PR) cases], eight patients received PD-1 inhibitor therapy after auto-HSCT as consolidation therapy. All patients maintained a CR status after transplantation, and they exhibited significantly improved progression-free survival (PFS) rates compared with those who did not undergo sequential auto-HSCT (4-year PFS rates: 100% vs 53.5% ; P=0.041). The incidence of immune-related adverse events was 29%, with only one patient experiencing grade≥3 adverse reactions, which indicated a favorable safety profile for the treatment approach. Conclusions: PD-1 inhibitor monotherapy demonstrates notable efficacy and sustained response in patients with R/R cHL. PD-1 inhibitors combined with chemotherapy significantly improve response rates. Additionally, for salvage therapy-sensitive patients, consolidation treatment with PD-1 inhibitors after auto-HSCT exhibits the potential for prolonging PFS.

Abstract
Objective: To investigate the clinical and pathological features, treatment, and prognosis of gray zone lymphoma (GZL) . Methods: From July 2, 2013, to February 10, 2021, the clinical and pathological features, treatment, and outcomes of five patients with GZL at the Blood Diseases Hospital, Chinese Academy of Medical Sciences were studied retrospectively. Results: There were one male and 4 females, with a median age of 28 (16-51) years at diagnosis. Four patients had mediastinal (thymic) involvement, two of which had superior vena cava obstruction syndrome, and 3 patients had extra-nodal involvement. There was one case with a limited Ann Arbor stage and 4 cases with a progressive stage. Three patients had cHL-like pathomorphology with scattered Hodgkin-like cells, strongly positive for CD20, positive for CD30, and CD15 was negative; the other two patients had both cHL and DLBCL morphology, with some areas resembling Hodgkin cells and some areas resembling immunoblasts, strongly positive for CD30, and CD15 but negative CD20. Two patients were treated with cHL-like regimens for induction and achieved only partial remission; after salvage therapy with enhanced DLBCL-like regimens, all achieved complete remission (CR) . Three patients were treated with enhanced DLBCL-like immunochemotherapy regimens for induction, and two patients were effective, one of whom achieved CR. Four patients who did not achieve CR were given second or third-line salvage therapy, and all of them recovered. One patient lost parity, one died of disease progression at 35.9 months after diagnosis, and the remaining three maintained sustained remission. Conclusions: GZL is uncommon, usually affects younger patients, is mediastinal and is diagnosed using path morphology and immunophenotype. Patients with newly diagnosed GZL appear to be more sensitive to DLBCL-like immunochemotherapy regimens; relapsed or refractory patients were tended with non-cross-resistant combination chemotherapy or with new drugs.

Abstract
PURPOSE/OBJECTIVES The goal of the present study was to examine perceived barriers to achieving clinical competence in endodontics and explain how YouTube is used to supplement formal education in this discipline. METHODS Postgraduate endodontic students conducted focus groups with fourth-year dental students at NYU College of Dentistry. The discussion was facilitated by a semistructured interview guide. Open-ended questions about participants' perceived barriers to clinical competency in endodontics, experiences using YouTube to learn about clinical endodontics, and preferences for video format learning were asked. Demographic information was gathered. Thematic analysis of data was conducted and data collection was terminated once saturation was achieved. RESULTS Thirty fourth-year dental students were enrolled in the study. The majority, 96.7%, reported using YouTube as a learning tool for dental procedures and 83.3% to learn about endodontics, specifically. The following domains were explored during data analysis: barriers to clinical competency, YouTube uses/experiences, and content preferences. The following themes within barriers to clinical competency were identified: psychological, educational, and clinical. Within the YouTube domain, the following themes were examined: goals of use, timing and frequency of use, search strategies, benefit/ shortcomings of YouTube, and validity of content. Students primarily used YouTube to enhance confidence and understand procedural flow. CONCLUSION YouTube videos were primarily used to help students overcome perceived educational and psychological barriers that resulted in gaps in confidence and knowledge of performing endodontic procedures. Dental students placed high value on easily accessible video content of limited duration, where clinical procedures were performed on live patients.

Abstract
目的 探讨硼替佐米中枢神经系统(CNS)毒性的临床特点、诊断和治疗。 方法 报道5例由硼替佐米引起的CNS毒性患者并结合现有文献探讨其临床特点。 结果 5例患者中有4例在应用硼替佐米后出现了中枢性发热,主要表现为持续性高热、周身无汗、未能找到感染病灶、对退热药不敏感,停用硼替佐米后症状好转。4例患者中有3例伴随顽固性低钠血症,1例明确诊断为抗利尿不当综合征(SIAD),可能是硼替佐米同时影响了下丘脑体温调节中枢和抗利尿激素神经分泌细胞所致。1例患者诊断为可逆性后部脑病综合征(PRES),表现为应用硼替佐米后出现意识障碍,头CT示双侧半卵圆中心白质密度减低,停用硼替佐米后患者症状消失且未再复发。此外,我们还发现血小板计数可能与硼替佐米CNS毒性的严重程度相关。 结论 硼替佐米的CNS毒性非常罕见,表现为3种形式:SIAD、PRES和中枢性发热,及时识别和治疗对于预防不可逆的神经并发症非常重要。

Abstract
Background/purpose Immediate implant placement has been considered to be a successful treatment procedure. The bone plate perforation (BPP) may be one of severe complication and potentially life-threatening situation. The aim of this virtual study is to evaluate the influences of angled implant insertion on BPP during immediate implant installation in the posterior mandible. Materials and methods Cone beam computed tomography images of 488 posterior teeth from 61 patients were selected. Virtual immediate implant placement (VIIP) was performed at each posterior tooth following the appropriate axis with the prosthetic-driven planning and different deviation angles of 3-, 6-, or 9-degree. BPP was then examined from cross-sectional images obtained. Furthermore, the relation of lingual bony morphology and BPP were also determined. Results The incidence of buccal and lingual BPP increased as the deviation angle increased in posterior mandible area. Incidence of lingual BPP was significantly influenced by angular deviation and type of lingual bony morphology after adjusting for age, gender, tooth type, and right/left side. An increase in incidence odds of over 6-fold (OR = 6.583) was noted for placements angled by 9° compared with placements made without angulation, and an increase in incidence odds of over 3-fold (OR = 3.622) was noted for teeth with the undercut-type lingual morphology compared with the other types. Conclusion The present Results indicate that accurate selection of the implant insertion angle and full awareness of the bony anatomy at the implant recipient site are essential to prevent BPP in the posterior mandible.

Abstract
目的 探讨成人急性淋巴细胞白血病(ALL)患者首疗程诱导治疗结束时微小残留病(MRD1)检测对自体造血干细胞移植(auto-HSCT)预后的意义。 方法 回顾性分析2006年2月1日至2017年4月30日行auto-HSCT的87例有流式细胞术MRD1检测结果的ALL患者临床资料,分析MRD1与ALL患者auto-HSCT后复发、生存的关系。 结果 26例(29.9%)ALL患者MRD1阳性。高危免疫表型比例在MRD1阳性组显著高于MRD1阴性组(34.6%对14.5%,P=0.038),初诊时年龄、性别、谱系(T/B)、免疫表型(标危/高危)、高白细胞计数(B-ALL>30×109/L或T-ALL>100×109/L)比例、伴高危染色体/基因比例、第1次完全缓解到移植的时间、预处理方案在MRD1阴性组和阳性组中差异均无统计学意义(P值均>0.05)。MRD1阴性患者、MRD1阳性患者的5年无白血病生存(LFS)率分别为75.7%、29.6%(P<0.001),总生存(OS)率分别为72.7%、47.3%(P=0.004)。多因素分析结果显示MRD1阳性是影响患者OS的独立危险因素(HR=3.007,95% CI 1.256~7.200,P=0.013),MRD1阳性和高危免疫表型是影响患者LFS的危险因素(HR=3.986,95% CI 1.813~8.764,P=0.001;HR=2.981,95% CI 1.373~6.473,P=0.006)。 结论 auto-HSCT不能逆转MRD1阳性患者的不良预后。MRD1阴性且在强化治疗中持续保持阴性患者可选择auto-HSCT治疗。

Abstract
Objective: To investigate the clinical status of lymphoid tissue neoplasms patients with bacteria bloodstream infections, bacteriology and drug susceptibility results, and provide the basis for rational clinical anti-infection option. Methods: A retrospectively analysis of clinical data and bacterial susceptibility test results of patients with bacteria bloodstream infections from September 2010 to December 2014 was conducted. Results: A total of 134 cases including 107 patients with bloodstream infections were enrolled. 84 cases were male, 50 cases were female, the median age was 31 (12-71) years old. 112 cases were agranulocytosis, and 106 cases were severe agranulocytosis (ANC<0.1×10(9)/L) . 27 cases underwent hematopoietic stem cell transplantation, 100 cases received chemotherapy[33 cases with VD (I) CP±L (vincristine+daunorubicin/idarubicin + cyclophosphamide + prednison±asparaginasum) induction chemotherapy, 41 cases with intensive chemotherapy of Hyper-CVAD/MA or MA (mitoxantrone+cytarabine) , 26 cases with other chemotherapy regimens], and 7 cases were infected without chemotherapy. 10 patients discharged from hospital owing to treatment abandoning, 120 cases were cured through anti-infective therapy, 2 patients died of bacteria bloodstream infections, 1 patient died of sudden cardiac, and 1 patient died of GVHD after allogenic hematopoietic stem cell transplantation. A total of 144 strains were isolated, including 108 strains (75.0%) of Gram-negative bacteria and 36 strains (25.0%) of Gram-positive cocci. The susceptibility of Gram-negative bacteria to the carbapenems was 98.00%, and the adjustment treatment rate of carbapenems was 3.0%. The susceptibility of Gram-negative bacteria to the other antibiotics was 60.30%, and the adjustment treatment rate was 90.5%. The susceptibility of Grampositive cocci to the carbapenems was 49.3%, and to glycopeptides and linezolid was 100.0%. Comparing all patients'empirical use of antimicrobial agents with the drugs susceptibility results of blood cultures, 80.1% of the patients'initial drug selection was sensitive. Conclusion: The lymphoid neoplasms patients experienced bacteria bloodstream infections most often after receiving the chemotherapy regimens of treating acute lymphoblastic leukemia. The majority type of bacteria was Gram-negative bacteria. Drug susceptibility test showed that susceptibility of Gram-negative bacteria to the carbapenems was the highest, and the treatment adjustment rate was obviously lower. The susceptibility of Gram-positive cocci to glycopeptides and linezolid was high, and which could be applied to the patients with Gram-positive cocci sepsis on basis of susceptibility results in general.

Abstract
BACKGROUND The aim of the study is to determine if bone quality evaluation of surgically obtained bone core specimens using a stereomicroscope is reliable for determining bone quality at implant recipient sites. METHODS Bone quality was presurgically assessed in 122 edentulous ridges obtained from 62 patients using periapical radiographs and categorized according to the Lekholm and Zarb classification. During surgery, bone specimens were trephined, and bone types were immediately classified using a stereomicroscope. Microarchitectural characteristics of bone cores were evaluated after being scanned using microcomputed tomography (micro-CT). RESULTS Bone types of implant sites categorized from radiography and stereomicroscope had statistically similar distribution but poor interrater agreement. Using micro-CT, maxillae and mandibles showed significant differences in microarchitectural characteristics of bone cores. Bone volume (BV), total volume (TV), and trabecular thickness (Tb.Th) increased, whereas bone surface density (BS/BV) and open porosity (Po.[Op]) decreased in mandibular bone cores compared with those in maxillary bone cores. Moreover, micro-CT values of BV/TV and Po.(Op) statistically correlated with bone types assessed by stereomicroscopy, particularly in mandibles (adjusted means of BV/TV of Type 2 to 4 versus Type 1 decreasing from -9.88%, -15.09%, -29.31%; those of Po.(Op) ranged from 9.77%, 15.06%, 29.52% in an upward trend). However, such correlations were not found in maxillae or when bone types were classified using periapical radiographs. CONCLUSIONS Caution is needed when using presurgical periapical radiographs to predict bone quality at implant recipient sites. Surgically preserved bone core specimens, whenever obtainable, might offer additional information to accurately assess bone quality, particularly at mandibular implant sites.

Abstract
Background/purpose Periodontal diseases have been considered as a source of oral malodor or halitosis. Improvement of oral malodor in chronic periodontitis patients has recently been observed after nonsurgical periodontal therapy in combination with tongue cleaning and/or chlorhexidine mouth rinsing. The present study, however, evaluated the impact of nonsurgical periodontal therapy alone on the oral malodor in chronic periodontitis patients by comparing the intraoral concentrations of volatile sulfur compounds (VSCs) before and after nonsurgical therapy. Materials and methods Using a sulfide monitor, the total VSCs in exhaled breath were measured in 80 patients with chronic periodontitis prior to and 1 month after nonsurgical periodontal therapy (re-evaluation phase). Malodor was defined as a VSC score > 75 parts per billion (ppb) and > 110 ppb, respectively. Results Significantly lower level of VSCs was recorded at periodontal re-evaluation (55 ± 9.7 ppb) than before treatment (89 ± 16.3 ppb). Before treatment, 27 (34%) patients were considered to have malodor, defined as VSCs > 75 ppb. After treatment, 16 patients (20%) had VSC scores > 75 ppb, including 10 of 27 patients with baseline VSC scores > 75 ppb and six of 53 patients with baseline scores ≤ 75 ppb. The risk of malodor differed significantly before and after treatment (P = 0.035, McNemar's test). However, when malodor was defined as VSCs > 110 ppb, the difference in risk showed only borderline significance (P = 0.077). Conclusion On the basis of our findings, we suggest that nonsurgical periodontal therapy has a mild impact on oral malodor.

Abstract
Background/purpose High prevalence of bifid mandibular canals has been visualized with various types of computerized tomography (CT). Along the canals, a various ranged corticalization was recently reported. The depiction of the fine anatomic structures on multislice and cone-beam CT images was compared. Material and methods The presence or absence of the bifid canal was assessed on 327 images obtained by multislice CT (MSCT; n = 173) or by cone-beam CT (CBCT; n = 154), according to the configuration. The cortex thickness and distribution were also assessed. Results The prevalence of bifid canal detected by CBCT was significantly greater than that detected by MSCT (42.2% vs. 18.7% for hemi-mandibles and 58.4% vs. 30.6% for patients). Cortical thickness recorded by CBCT was significantly thinner than that recorded by MSCT (0.48 mm vs. 0.65 mm, P < 0.001); however, the distributions of corticalization detected by the two tomography methods were similar. There was a significant association of cortex thickness with CT type and corticalization degree (R2 = 0.530, P < 0.001). Conclusion Thinner cortices, but greater prevalence of bifid canals recorded by CBCT, compared to MSCT, suggests that clinicians should be cautious when using CT to interpret this fine anatomic structure.
