Curative effect evaluation by using Andrews' six elements for completed orthodontic treatment cases / 华西口腔医学杂志

OBJECTIVES@#To assess the treatment outcome of patients who completed their orthodontic treatment by using Andrews' six elements and the American Board of Orthodontic (ABO) objective grading system (OGS); to determine whether Andrews' six elements can be used as a new assessment system for patients who completed their orthodontic treatment.@*METHODS@#A total of 160 patients who completed their orthodontic treatment were included in the study. The participants were randomly selected from patients who completed their orthodontic procedures in Kunming Medical University Affiliated Stomatological Hospital during the period of 2015 to 2019. The retrospective completed cases were examined in accordance with the Andrews' six elements and ABO measuring scales. Scores were assigned to each tooth in each category. All the measurement items in both evaluation criteria, the composite category score, and the total score were calculated. The passing and potential passing rates of the completed cases were compared with two measuring scales via the Chi-square test.@*RESULTS@#The passing rate for the evaluation of cases by using the Andrews' six elements measuring scale was 83.8%, and that for the evaluation of cases by using the ABO measuring scale was 86.3%. The differences in achieving the standard between the cases of Andrews' six elements and ABO-OGS via the Chi-square test were statistically insignificant (@*CONCLUSIONS@#The performance of Andrews' six elements was comparable with that of ABO-OGS in assessing the treatment outcome of patients who completed their orthodontic treatment. Andrews' six elements can be used as a new system for assessing the treatment outcome of patients who completed their orthodontic treatment. It demonstrated particular advantage in controlling facial profile, and had just completed material of patients who completed their orthodontic treatment it can measure. The Andrews' six elements measuring scale is convenient to disseminate and use.

Impact of different admission ways on treatment efficiency in patients with acute ST-segment elevation myocardial infarction / 中华心血管病杂志

Objective: To analyze the impact of different admission ways on the timeliness of percutaneous coronary intervention and in-hospital mortality in patients with acute ST-segment elevation myocardial infarction (STEMI). Methods: A total of 1 044 patients with STEMI, who received primary percutaneous coronary intervention (PPCI) in 9 hospitals in Chengdu from January 2017 to June 2019, were retrospectively enrolled. According to the admission ways, patients were divided into ambulance group (n=100), self-transport group (n=584) and transferred group (n=360). Timeliness and in-hospital mortality were compared among the groups. Indicators of timeliness included the time from symptoms onset to arrive at the hospital, the time from arrive at the hospital to balloon and the total myocardial ischemia time (the time from symptoms to balloon). Multivariate logistic regression analysis was used to verify whether the admission ways was the determinant for in-hospital death in STEMI patients receiving PPCI. Results: The median total myocardial ischemic time in the ambulance group was significantly shorter than that in the self-transport group (180.0 (135.0, 282.0) minutes vs. 278.0 (177.8, 478.5) minutes, P<0.05) and the transferred group (180.0 (135.0, 282.0) minutes vs. 301.0 (204.3, 520.8) minutes, P<0.05). The median time from symptoms to door was as follows: ambulance group<self-transport group<transferred group (100.0 (56.3, 198.0) minutes vs. 149.0 (72.0, 313.5) minutes vs. 238.0 (135.0, 545.0) minutes, all P<0.05). The median door-to-balloon time was significantly shorter in the ambulance group and transferred group than in the self-transport group (75.0 (44.3, 101.8) minutes vs. 97.0 (71.0, 140.5) minutes, 67.0 (40.0, 91.8) minutes vs. 97.0 (71.0, 140.5) minutes, both P<0.05). There was no significant difference in all-cause mortality among the three groups (P>0.05). Multivariate logistic regression analysis showed that admission way was not significantly associated with in-hospital death (P>0.05). Conclusions: STEMI patients, who are admitted through the medical emergency system, are more likely to receive timely interventional therapy.Different admission ways have no impact on in-hospital mortality.

Acupuncture combined with other therapies for osteoporosis: A network meta-analysis / 中国组织工程研究

BACKGROUND: Comparative study results between the treatment efficiency of acupuncture plus other combination therapy and western medicine therapy in the treatment of knee osteoarthritis remain controversial. Currently, meta-analysis studies mainly focus on comparison of the efficacy between single acupuncture treatment, acupuncture plus western medicine combination therapy and western medicine, but there is a lack of investigation on acupuncture combined with other therapies. It is difficult to fully understand the efficacy of acupuncture. OBJECTIVE: To compare the effects of acupuncture therapy, conventional western medicine and Chinese medicine on osteoporosis treatment by network meta-analysis. METHODS: A search was performed on the CNKI, VIP, WanFang, SinoMed, PubMed, and Cochrane Library databases to include the randomized controlled trials of different acupuncture treatments for osteoporosis. Relevant data were extracted after screening the literature according to relevant inclusion and exclusion criteria, and the quality of the included literature was evaluated. Literature data analysis and mapping were performed using Stata 14.0 software. RESULTS AND CONCLUSION: Thirty-four randomized controlled trials were included, involving seven interventions, such as single acupuncture treatment, single western medicine treatment, single Chinese medicine treatment, acupuncture plus western medicine combination therapy, acupuncture plus Chinese medicine combination therapy, Chinese medicine + western medicine treatment, acupuncture + Chinese medicine + western medicine combined treatment. (1) In the treatment efficiency, acupuncture combined with traditional Chinese medicine is the best in the treatment of primary osteoporosis, and acupuncture combined with traditional Chinese medicine, acupuncture combined with western medicine and acupuncture combined with traditional Chinese medicine western medicine were significantly better than traditional Chinese medicine combined with western medicine (P 0.05). In the included studies, a very small number of patients developed acupuncture and blood stasis after acupuncture, but no fainting or unreported, and no other side effects were found. To conclude, acupuncture combined with other therapies can improve the efficiency, increase the bone mineral density and alleviate pain.

Factors influencing orthodontic treatment time for non-surgical Class III malocclusion

ABSTRACT To improve orthodontic treatment efficiency, orthodontists must know which variables could interfere with orthodontic treatment time. Objective: To identify variables and their effect size on orthodontic treatment time of Class III malocclusion. Material and Methods: Forty-five Class III malocclusion cases were selected from 2008 patients’ records. Clinical charts, cephalometric radiographs, and pre and posttreatment dental casts were evaluated. Age, sex, PAR index at T1 and T2, overjet, missing teeth, extractions, number of treatment phases, missed appointments, appliance breakages, and cephalometric variables SNA, SNB, ANB, Wits, SnGoGn, CoA, CoGn, IMPA, 1.PP were investigated by multiple linear regression analysis and stepwise method at p<0.05. The sample was also divided into two groups: Group 0-2 (patients who had missed two clinical appointments or less) and Group >2 (patients who missed more than 2 appointments), to detect the influence of this data on treatment time and the quality of the treatment (PAR T2). Results: Average treatment time was 30.27 months. Multiple regression analysis showed that missed appointment (R2=0.4345) and appliance breakages (R2=0.0596) are the only variables able to significantly predict treatment duration. Treatment time for patients who missed more than 2 appointments was nearly one year longer. However, no significant influence on PAR T2 was observed for those patients. Conclusion: Orthodontic treatment duration in Class III patients is mainly influenced by factors related to patient compliance. Patients who missed more appointments did not show worse orthodontic finishing, but longer treatment. No occlusal, cephalometric, or demographic variable obtained before treatment was able to give some significant prediction about treatment time in Class III patients.

Do customized orthodontic appliances and vibration devices provide more efficient treatment than conventional methods? / 대한치과교정학회지

The incorporation of technological advances in the field of clinical orthodontics to increase treatment efficiency has led to the development of customized appliances (Insignia®), archwires (Suresmile®), and the production of devices to enhance tooth movement (Acceledent®). This review presents a comprehensive study of the literature concerning these products, and analyzes the available evidence of their efficiency. To date, one pilot study has evaluated the efficiency of the Insignia® system, three retrospective studies have assessed the efficiency of the Suresmile® system, and a few Acceledent® reports have described its effect on treatment time. Critical appraisal of the reviewed papers revealed that the efficiency of the Insignia® system cannot be confirmed based on the available evidence, while the use of Suresmile® can reduce overall treatment time in simple cases. The acceleration of tooth movement by Acceledent® devices has not yet been confirmed.

Intraocular cytokines in retinal vein occlusion and its relation to the efficiency of anti‑vascular endothelial growth factor therapy.

Purpose: To analyze the change in the concentration of intraocular cytokines (ICs) in patients with retinal vein occlusion (RVO) before and after intravitreal ranibizumab therapy (IVR), and to find the correlations of IC with clinical activity of RVO and efficiency of treatment. Materials and Methods: Forty‑four patients aged 46–79 years old (mean age: 60.7 ± 7.5 years old) with RVO and macular edema (18 patients – with central RVO, 26 – with branch RVO) treated with IVR were included into the study. The concentrations of 27 cytokines were simultaneously measured in aqueous humor by flow fluorometry using Bio‑Plex Pro Human Cytokine Panel, 27‑Plex (Bio‑Rad Laboratories, USA) at baseline and after the first IVR. Control group consisted of 20 age‑matched patients. Results: The levels of 11 cytokines (vascular endothelial growth factor [VEGF], receptor antagonist interleukin‑1, interleukin‑6 [IL‑6], IL‑8, IL‑9, IL‑10, IL‑12r70, IL‑13, IL‑15, monocyte chemotactic protein‑1 [MCP‑1], regulated on activation, normal T expressed and secreted) were significantly (P < 0.05) different compared to control and significantly (P < 0.05) changed after IVR both in central and branch RVO. The patients were divided into two groups: the first ‑“effective” and the second ‑ “partially effective” therapy. The second group characterized by the higher concentrations of VEGF, IL‑8, IL‑10, IL‑17, and MCP‑1 at baseline compared to the first group. Conclusion: The patients with RVO were characterized by the increased levels of VEGF and other pro‑ and anti‑inflammatory cytokines and chemokines. Aqueous concentration of cytokines were different in patients with central and branch RVO and significantly changed after IVR. Insufficient response to IVR was associated with activation of immune‑inflammatory processes.

Prevalence and treatment follow-up of drug-resistant extra-pulmonary tuberculosis in rural communities in Narshingdi, Bangladesh.

Tuberculosis is a chronic communicable disease. Infections are initially asymptomatic and latent but eventually progresses to active disease, which, if left untreated, may have ≥50% mortality. In 2011, an anti-tuberculosis drug resistance survey in Narsingdi, Bangladesh enrolled both new and retreatment patients. In the study, a number of villages were randomly selected and 152 extra pulmonary tuberculosis (EPTB) patients were identified. All the patients received treatment with standardized first-line drug (FLD) regimens and were investigated to document treatment efficiency. Among the patients, 34 were reported in lower income, 112 in medium income and only 06 in higher income group. Farmers (16.4%) in low income group, and female housewives (41.4%) in medium income group were mostly infected. Silicosis and malnutrition were assumed responsible for high EPTB cases in farmers and housewives respectively. The working youth groups (25-34) were found most vulnerable. Extra pulmonary TB sites of infection was found pleural TB 29.6% patients, glands TB 24.3% patients, abdominal TB 21.0% patients, spinal TV 19.7% patients, tubercular meningitis 436% patients & tubercular pericarditis 0.65% patient. Multi-drug resistant (MDR) EPTB was detected in both new and retreatment patients. Patients with MDR-EPTB who had been declared cured with first-line anti-TB treatment had a high rate of TB recurrence and death. The rate of TB recurrence and death was high four years after MDR-TB patients were judged to have been cured. PTB patients in Bangladesh had high recurrence and death rates even after treatment with standardized FLD regimens, reinforcing the need for early survey, diagnosis and treatment, including assessment of treatment outcomes.
