Expert consensus on difficulty assessment of endodontic therapy

Endodontic diseases are a kind of chronic infectious oral disease. Common endodontic treatment concepts are based on the removal of inflamed or necrotic pulp tissue and the replacement by gutta-percha. However, it is very essential for endodontic treatment to debride the root canal system and prevent the root canal system from bacterial reinfection after root canal therapy(RCT). Recent research, encompassing bacterial etiology and advanced imaging techniques, contributes to our understanding of the root canal system’s anatomy intricacies and the technique sensitivity of RCT. Success in RCT hinges on factors like patients, infection severity, root canal anatomy, and treatment techniques. Therefore, improving disease management is a key issue to combat endodontic diseases and cure periapical lesions. The clinical difficulty assessment system of RCT is established based on patient conditions, tooth conditions, root canal configuration, and root canal needing retreatment, and emphasizes pre-treatment risk assessment for optimal outcomes. The findings suggest that the presence of risk factors may correlate with the challenge of achieving the high standard required for RCT. These insights contribute not only to improve education but also aid practitioners in treatment planning and referral decision-making within the field of endodontics.

Construction of a nomogram model to predict technical difficulty in performing laparoscopic sphincter-preserving radical resection for rectal cancer

BACKGROUND Colorectal surgeons are well aware that performing surgery for rectal cancer becomes more challenging in obese patients with narrow and deep pelvic cavities.Therefore,it is essential for colorectal surgeons to have a comprehensive understanding of pelvic structure prior to surgery and anticipate potential surgical difficulties.AIM To evaluate predictive parameters for technical challenges encountered during laparoscopic radical sphincter-preserving surgery for rectal cancer.METHODS We retrospectively gathered data from 162 consecutive patients who underwent laparoscopic radical sphincterpreserving surgery for rectal cancer.Three-dimensional reconstruction of pelvic bone and soft tissue parameters was conducted using computed tomography(CT)scans.Operative difficulty was categorized as either high or low,and multivariate logistic regression analysis was employed to identify predictors of operative difficulty,ultimately creating a nomogram.RESULTS Out of 162 patients,21(13.0%)were classified in the high surgical difficulty group,while 141(87.0%)were in the low surgical difficulty group.Multivariate logistic regression analysis showed that the surgical approach using laparoscopic intersphincteric dissection,intraoperative preventive ostomy,and the sacrococcygeal distance were independent risk factors for highly difficult laparoscopic radical sphincter-sparing surgery for rectal cancer(P<0.05).Conversely,the anterior-posterior diameter of pelvic inlet/sacrococcygeal distance was identified as a protective factor(P<0.05).A nomogram was subsequently constructed,demonstrating good predictive accuracy(C-index=0.834).CONCLUSION The surgical approach,intraoperative preventive ostomy,the sacrococcygeal distance,and the anterior-posterior diameter of pelvic inlet/sacrococcygeal distance could help to predict the difficulty of laparoscopic radical sphincter-preserving surgery.

Effect of Mouth Opening Training Stick Combined with Oral Massage on Mouth Opening Difficulty in Head and Neck Cancer Patients after Treatment

Objective: To study the application effect of mouth-opening training sticks combined with oral massage on patients with mouth-opening difficulty after treatment for head and neck cancer. Methods: Using convenient sampling, 60 patients with mouth-opening difficulty after treatment for head and neck cancer admitted to the Oncology Department from February 2022 to October 2023 were selected for a 2-week exercise and nursing program. The patients were divided into a control group (February 1, 2022 to November 30, 2022) and an observation group (December 1, 2022 to October 31, 2023), with 30 patients in each group. The control group underwent routine mouth-opening functional exercises combined with cork for oral support training, while the observation group underwent routine mouth-opening functional exercises combined with oral massage and mouth-opening training sticks for oral support training. The mouth-opening degree, mouth-opening difficulty level, comfort level, compliance, and quality of life were observed in both groups. Results: Before the intervention, there were no statistically significant differences in mouth-opening degree and mouth-opening difficulty level between the two groups (P > 0.05). After the intervention, the mouth-opening degree, mouth-opening difficulty level, oral comfort level, compliance, and QLICP-HN scores in the observation group were all better than those in the control group, with statistically significant differences (P < 0.05). Conclusion: The combination of mouth-opening training sticks and oral massage with mouth-opening functional exercises can effectively improve the degree of mouth-opening difficulty, enhance oral comfort, increase compliance with mouth-opening exercises, and improve quality of life.

Ableism and (Neo)Racism in School Placement Processes in Quebec: School Personnel Interpretations of Immigrant Student Difficulties - A Secondary Publication

The school placement processes of students from immigrant backgrounds considered to be in“difficulty”is an international concern at the intersection of works relating to special education and those concerning the school experiences of students from immigrant backgrounds or racialized groups.The research problem of this article concerns the identification of these students as disabled or as having adjustment or learning difficulties.From a perspective anchored in Disability Critical Race Studies,this ethnographic study documents different interpretations of perceived difficulties made by school actors with regard to seven primary school students from immigrant backgrounds.Five interpretation types are presented:(1)medicalization by dismissal of cultural markers,(2)medicalization by professional constraint,(3)medicalization by cultural deficit,(4)precautionary wait,and(5)cultural differentialism.Our results help to shed light on the special education overrepresentation phenomenon regarding these students and to understand how ableism and(neo)racism contribute to it.

Proteomic analysis of overweight/obesity and related abnormal glucose and lipid metabolism caused by phlegm-dampness retention

Objective:To investigate the proteomic characteristics of overweight/obesity and related abnormal glucose and lipid metabolism caused by phlegm-dampness retention to identify related biomarkers.Methods:Seventy-one subjects were enrolled in the study.We assessed blood glucose,blood lipids,body mass index(BMI),and phlegm-dampness pattern,which was confirmed by a traditional Chinese medicine clinician.Of the participants,we included healthy participants with normal weight(NW,n=23),overweight/obese participants with normal metabolism(ONM,n=19),overweight/obese participants with pre-diabetes(OPD,n=12),and overweight/obese participants with marginally-elevated blood lipids(OML,n=17).Among them,the ONM,OPD,and OML groups were diagnosed with phlegmdampness pattern.The data-independent acquisition(DIA)method was first used to analyze the plasma protein expression of each group,and the relevant differential proteins of each group were screened.The co-expressed proteins were evaluated by Venn analysis.The pathway analyses of the differential proteins were analyzed using Ingenuity Pathway Analysis(IPA)software.Parallel reaction monitoring(PRM)was used to verify the differential and common proteins in each group.Results:After comparing ONM,OPD,and OML groups with NW group,we identified the differentially expressed proteins(DEPs).Next,we determined the DEPs among OPD,OML,and ONM groups.Using Venn analysis of the DEPs in each group,24 co-expressed proteins were screened.Two co-expressed proteins were verified by PRM.IPA analysis showed that pathways including LXR/RXR activation,acute phase response signaling,and FXR/RXR activation were common to all three groups of phlegmdamp overweight/obesity participants.However,the activation or inhibition of these pathways was different among the three groups.Conclusion:Participants with overweight/obesity have similar proteomic characteristics,though each type shows specific proteomic characteristics.Two co-expressed proteins,VTN and ORM1,are potential biomarkers for glucose and lipid metabolism diseases with overweight/obesity caused by phlegmdampness retention.

Clinical Efficacy of Modified Erchen Decoction on Cervical Spondylotic Vertebral Arteriopathy with Stagnation and Blockade of Phlegm-dampness Syndrome and Effects on Cerebral Blood Flow Parameters

OBJECTIVE: To observe the effect of Modified Erchen Decoction on cervical spondylotic vertebral arteriopathy with stagnation and blockade of phlegm-dampness syndrome and effects on cerebral blood flow parameters. METHODS: A total of 80 cervical spondylotic vertebral arteriopathy(CSA) patients with stagnation and blockade of phlegmdampness syndrome admitted to our hospital from October 2016 to April 2017 were selected and randomly divided into observation group and control group, with 40 cases in each group. The observation group was treated with Modified Erchen Decoction and the control group was given conventional treatment with Western medicine. After 4 weeks of treatment, the main clinical symptoms and signs(vertigo, neck and shoulder pain, headache, psychological and social adjustment, daily life and work) and cerebral blood flow parameters [the peak values of intracranial vertebral-basal artery diastolic blood flow velocity(Vd) and systolic blood flow velocity(Vp)] were compared between the 2 groups. The total clinical effective rate and adverse reactions during treatment were also compared. RESULTS: After treatment, the total effective rate of the observation group was 90.0%, which was significantly higher than that of the control group(77.5%). The difference between the two groups was statistically significant(P < 0.05). After treatment, The scores of vertigo, neck and shoulder pain, headache, psychology and society adaptation, daily life and work were significantly increased(P < 0.05), and the above scores of the observation group were increased more obviously. The difference between the groups was statistically significant(P < 0.05). After treatment, the levels of Vd and Vp were significantly increased(P < 0.05), and the increase of the above indexes was more obvious in the observation group. The difference between the 2 groups was statistically significant(P < 0.05). There were no significant abnormalities in blood routine, urine routine, liver function and renal function. There was no significant difference in the incidence of adverse reactions between the 2 groups.(P > 0.05). CONCLUSION: The treatment of vertebral artery type cervical spondylopathy with stagnation and blockade of phlegm-dampness syndrome by Modified Erchen Decoction can effectively relieve the main clinical symptoms and signs, improve cerebral blood flow parameters, and improve the peak values of vertebral-basal artery diastolic blood flow velocity(Vd) and systolic blood flow velocity(Vp), which is safe and effective, and helps to promote the recovery of cervical function.

Fecal-associated microbiome differences between phlegm-dampness constitution and balanced constitution

Objective: This study aimed to explore the structural and functional characteristics of the fecalassociated microbiome(FAM) between the phlegm-dampness constitution(PDC) and balanced constitution(BC), and to screen the related specific operational taxonomic unit(OTU) biomarkers.Methods: This was a cross-sectional study. After strictly identifying the constitution of subjects, their clinical index was recorded and counted. Fecal samples were collected for 16S rDNA sequencing. Alpha diversity, beta diversity, and the relative abundance of dominant bacterial taxa were used to describe the FAM structure, and the Wilcoxon rank-sum test, Metagenome Seq, and linear discriminant analysis effect size(LEf Se) were used to screen specific bacterial taxa. Specific OTUs were screened to construct receiver operating characteristic(ROC) curves.Results: Thirty-two subjects were enrolled, including 22 subjects with BC and 10 subjects with PDC.There were significant differences in cold preference, levels of aspartate transaminase, β2-microglobulin,and creatine kinase MB, and alpha diversity indices(Shannon and Shannoneven) between the two groups. In principal coordinate analysis by abund-jaccard distance measure and partial least squares discriminant analysis, bacterial communities clustered separately between the two groups. Furthermore,based on Metagenome Seq, LEf Se, and the Wilcoxon rank-sum test, a total of 43, 18, and 130 OTUs were differentially distributed between BC group and PDC group, respectively, and OTU200, OTU133, and OTU353 were screened when P≤.01. The area under the ROC curve constructed from the 3 selected OTUs was 0.93.Conclusion: The FAM structure and related functional characteristics of the PDC group differed from those of the BC group. In particular, OTU200, OTU133, and OTU353 can be used as unique markers of PDC to assist clinical diagnosis.

Morbi-Mortality Linked to Unsafe Abortions—Difficulties in Accessing Safe Abortions in Cameroon: Meta-Analysis and Systematic Review

Background: Unsafe abortions are one of the leading causes of maternal mortality, especially in developing countries. In Cameroon, the maternal mortality rate remains high, and the scarcity of data on abortions leads to a lack of solid evidence to advocate on the extent of the abortions related complications. Our objective was to evaluate the unsafe abortions related complications, and to assess the difficulties of accessing safe abortions in our setting. Methods: We carried out a meta-analytic and systematic review in the biomedical databases MEDLINE (Pubmed), Google Scholar and African Journal Online concerning unsafe abortions and/or difficulties in accessing safe abortions in Cameroon. The keywords used for the search are seen in table I. Selection of studies was simultaneously done by two authors. Data were extracted through a form designed on Google Form. We used a random-effect model for proportion estimation, and The I2 and Q statistics to assess the extent of heterogeneity. Results: A total of 430 studies were identified, from which 28 were included and analysed. About 5% (95% CI: 3 - 7) of unsafe abortions leads to death. The contribution of unsafe abortions in maternal deaths was 23% (95% CI: 20 - 27). The rate of severe bleeding and/or anemia were 40% (95% CI: 18 - 63) and the rate of infection was 17% (95% CI: 7 - 28), dominated by pelvic infections, pelviperitonitis, severe sepsis, and septic shock. Case reports described uterine perforations, uterine rupture during the following pregnancy. Abortion was performed in the practitioner’s or patient’s home in 41.4% of cases, in a health center in 35.1% of cases, in a private clinic in 21.2% of cases, drugs selling places and in traditional healer clinics. The restriction of abortion laws, the stigma surrounding abortion and its consequences at any level of the society, lead to the underreporting of unsafe abortions and a deep reluctance to advocate for safe abortion services. Conclusion: The strengthening of awareness campaigns for provider behavior change communication, family planning, the de-stigmatization of abortions, the training of health personnel in post-abortion care, a multidisciplinary and multicentric action would contribute to the reduction in morbidity and mortality due to abortions.

Glucose-6-Phosphate Dehydrogenase Deficiency: Difficulties in Diagnosis at the Souro Sanou University Hospital, Burkina Faso

Glucose-6-phosphate dehydrogenase deficiency is the most common enzymopathy worldwide. The precise prevalence of G6PD is unknown in Burkina Faso. The objective of the study was to describe the difficulties to diagnose this disease at the Souro Sanou University hospital (CHUSS) in Bobo-Dioulasso. It involved five patients comprising one child with homozygous SS sickle cell disease, one adolescent screened following a family investigation, and three adults including a man and two women. Blood smear stained with May Grunwald Giemsa was performed to look for specific signs of G6PD-deficient red blood cell and brilliant cresyl Blue for Heinz Bodies. A microscope Olympus BX53 equipped with a Camera (XC10) and connected to a computer was used to read blood smears and capture images. Genes sequencing by Sanger method were performed in a specialized laboratory in molecular genetics. For each analysis, the protocol and instructions of the equipment and reagent manufacturer were applied. Of the five patients, three had anemia and only one had hyperreticulocytosis. Two patients had biological signs of hemolysis and one patient had an elevated CRP. Blood smear stained with MGG and cresyl blue showed specific signs of G6PD-deficient red blood cells and Heinz bodies in all patients. Biochemical analysis and molecular typing confirmed G6PD deficiency. The presence of G6PD-deficient red blood cells in the blood smear guides the diagnosis of G6PD deficiency. The diagnosis is biochemical and is based on the combined measurement of G6PD plus pyruvate kinase and/or hexokinase.

Transfer learning-based super-resolution in panoramic models for predicting mandibular third molar extraction difficulty: a multi-center study

Background:This study aims to predict the extraction difficulty of mandibular third molars based on panoramic images using transfer learning while employing super-resolution(SR)technology to enhance the feasibility and validity of the prediction.Methods:We reviewed a total of 608 preoperative mandibular third molar panoramic radiographs from two medical facilities:the First Affiliated Hospital of Zhengzhou University(n=509;456 in the training set and 53 in the test set)and the Henan Provincial Dental Hospital(n=99 in the validation set).We conducted a deep-transfer learning network on high-resolution(HR)panoramic radiographs to improve the longitudinal resolution of the images and obtained the SR images.Subsequently,we constructed models named Model-HR and Model-SR using high-dimensional quantitative features extracted through the Least Absolute Shrinkage and Selection Operator method.The models’performances were evaluated using the receiver operating characteristic curve(ROC).To assess the reliability of the model,we compared the results from the test set with those of three dentists.Results:Model-SR outperformed Model-HR(area under the curve(AUC):0.779,sensitivity:85.5%,specificity:60.9%,and accuracy:79.8%vs.AUC:0.753,sensitivity:73.7%,specificity:73.9%,and accuracy:73.7%)in predicting the difficulty of extracting mandibular third molars.Both Model-HR(AUC=0.821,95%CI 0.687–0.956)and Model-SR(AUC=0.963,95%CI 0.921–0.999)demonstrated superior performance compared to expert dentists(highest AUC=0.799,95%CI 0.671–0.927).Conclusions:Model-SR yielded superior predictive performance in determining the difficulty of extracting mandibular third molars when compared with Model-HR and expert dentists’visual assessments.

困难静脉评估量表在不同年龄血管通路管理中的应用进展

困难静脉通路(difficult intravenous access,DIVA)是指因为多种因素,如患者肢体肥胖、肢体局部肿胀、血管反复穿刺、静脉使用高渗液、刺激性药物等,使患者的血管无法直视或触摸不到充盈的静脉,而造成临床护士在建立静脉通路时出现穿刺困难的状态[1-2],且穿刺失败次数≥3次的情况[1,3-4]。2008年YEN等[5]研究发现,DIVA发生率为32.8%。DIVA带来的反复静脉穿刺会增加血管药物外渗、静脉炎、感染等并发症的风险,并增加患者痛苦及护士工作量,打击护士工作信心[6]。研究显示[7],12%的患者需要2次尝试才能成功建立静脉通路,而4%和3%的患者分别需要3次和4次及以上的穿刺来建立静脉通路。穿刺前有效识别DIVA对于降低反复静脉穿刺,提高穿刺成功率有重要意义。困难静脉量表是识别DIVA、降低反复穿刺率的有效工具[5],可协助临床护理人员对困难静脉进行评估和判断,并根据DIVA评分等级选择超声等可视化辅助工具,提高第一次穿刺成功率[4]。

按病种分类的疾病诊疗难度测度及应用研究

本研究首次界定了按病种分类的疾病诊疗难度的内涵,运用按病种的疾病发生概率、平均总费用与治愈好转率对病种诊疗难度系数进行测算。采用七县(市)区2017年新农合医保报销数据计算住院病种诊疗难度系数,并绘制“病例数—诊疗难度系数”分布图与拟合曲线,结果符合病种发生的实际状况。对其中两个样本县分别计算相同病种的诊疗难度系数,并进行配对资料秩和检验,计算结果不存在显著差异(P=0.73),提示该算法结果稳健,能够较好地描绘病种的发生与分布规律。测度结果能够用于明确医疗机构病种诊疗范围,刻画医疗服务供给与需求行为,但也存在较为依赖样本量、权重确定较为主观等问题。
