Research progress on dental materials for preventing root caries / 口腔疾病防治

@#The high incidence and untreated rate of root caries, a common and frequently occurring oral disease with challenging treatment in elderly individuals, is the main cause of tooth loss among elderly people, as rapid development results in pulpitis and periapical periodontitis or residual crown and root, which has been regarded as one of the common chronic oral diseases seriously affecting the quality of life of elderly people. Thus, early intervention and prevention are important. Traditional dental materials for preventing root caries have been widely used in clinical practice; however, they have the disadvantages of tooth coloring, remineralization and low sterilization efficiency. A series of new dental materials for preventing root caries have gradually become a research hotspot recently, which have the advantages of promoting the mineralization of deep dental tissue, prolonging the action time and enhancing adhesion. Future caries prevention materials should be designed according to the characteristics of root surface caries and the application population and should be developed toward simplicity, high efficiency and low toxicity. This review describes current research regarding anti-caries prevention material application, serving as a theoretical underpinning for the research of root caries prevention materials, which is important for both promotion in the effective prevention of root caries and improvement in the status of oral health and the quality of life among old people.

Research on supervision strategy of high risk areas of hospital incorrupt government based on traditional chinese medical theory of preventing diseases / 中华医院管理杂志

In recent years, the frequency of corruption incidents in public hospitals in China has increased, and it is particularly important to strengthen the construction of hospital incorrupt politics. Based on the traditional chinese medical theory of preventing diseases, the author deeply discusse the prevention and control strategies in high-risk areas of public hospitals incorrupt from 3 aspects: prevention before disease onset, prevention of disease from exacerbating and prevention of recovery from relapse. Based on the common problems found in the political inspection of Beijing municipal health system and large-scale hospitals in the latest years, an incorrupt government risks list of high-risk areas in hospital had been sorted out; A tertiary hospital and its 4 entrusted hospitals were selected to conduct self-inspection on the key links of important power activities and authority behaviors in accordance with the incorrupt government risks list, and putting forward targeted supervision strategies for these problems. Since the implementation of supervision strategy for high-risk areas in the tertariy hospital and its 4 entrusted hospitals in May 2021, the number of letters and visits in the 5 aspects of medicine procurement, equipment procurement, consumables and reagents procurement, engineering construction and logistics service procurement were significantly reduced. Based on the traditional chinese medical theory of preventing diseases, the supervision strategy in high-risk areas could effectively improve the pertinence, operability and effectiveness of discipline inspection and supervision in hospital, and provide a reference for the construction of incorrupt government in public hospitals.

This paper reports on the experience of a group of students, associated with the Tutorial Education Program of the Ministry of Education in Brazil, with a project to promote emotional self-regulation skills and interpersonal problem--solving skills in a preschool. Pre school is known as a strategic period for prevention and promotion actions in mental health and schools are the most proper environment for proactive actions. About 80 students participated, with an average age of 5 years old, from four second period classes of a public city preschool in the city of Juiz de Fora, state of Minas Gerais. The intervention was subdivided into two axes: emotional self-regulation and interpersonal problem-solving. Each axis was developed through six weekly meetings, using playful and audiovisual resources. The intervention was assessed positively by the teachers, who reported that the children learned and used the concepts, applying them in the classroom. In conclusion, projects like this should be stimulated more often in schools, given their potential for preventing aggressive behaviors and promoting socio-emotional development in early childhood.

The controlled study of efficacy and safety of infusion of ilaprazole sodium versus esomeprazole sodium in prevention of peptic ulcer rebleeding / 中华消化杂志

Objective:To explore the efficacy and safety of intermittent infusion of ilaprazole sodium and high-dose continuous infusion of esomeprazole sodium in preventing rebleeding in patients with peptic ulcer bleeding after successful endoscopic hemostasis.Methods:This is a multi-center, interval randomized, double-blind, double-dummy, parallel controlled study. From March 3rd to June 15th, 2021, 151 patients with high risk of peptic ulcer bleeding and successfully underwent endoscopic hemostasis from 33 hospitals including the First Affiliated Hospital of Zhejiang University School of Medicine were enrolled. Patients were interval randomly divided into the trial group (74 cases) and the control group (77 cases). Patients in the trial group received intermittent intravenous infusion of ilaprazole sodium once daily (20 mg administered as a 60 min intravenous infusion on day 1, and 10 mg administered as a 30 min intravenous infusion on day 2 and 3); patients in the control group received continuous intravenous infusion of esomeprazole sodium for 72 h (esomeprazole sodium 80 mg at first dose in half an hour, and 8 mg per hour continuous intravenous infusion for 71.5 h). After intravenous infusion treatment, patients of both groups were given oral ilaprazole enteric-coated tablets, 10 mg each time, once a day for 4 d. The rebleeding rate after 72 h and within 7 d after treatment and the proportion of patients who received endoscopic retreatment or surgery due to rebleeding within 72 h after treatment were analysised based on the full analysis set (72 cases in the trial group and 75 cases in the control group); and the incidence rate of adverse reactions was observed in the two groups based on the safety analysis set (74 cases in the trial group and 76 cases in the control group). Chi-square test or Fisher exact probability test was used for statistical analysis.Results:There was no rebleeding case in the trial group within 72 h and 1 case of rebleeding within 7 d (1.39%, 1/72). In the control group, there was 1 case of rebleeding (1.33%, 1/75) within 72 h and 4 cases of rebleeding (5.33%, 4/75) within 7 d. There was no significant difference in rebleeding rate either after 72 h or within 7 d after treatment between the two groups (both P>0.05). Within 72 h of treatment, no patients in both groups needed endoscopic or surgical retreatment due to rebleeding. Adverse reactions occurred in 5 cases (6.8%, 5/74) and 6 cases (7.9%, 6/76) in the trial group and control group, respectively, which recovered spontaneously without treatment. No serious adverse reactions occurred in both groups. Conclusion:In patients with high-risk peptic ulcer bleeding with successful endoscopic hemostasis, intermittent intravenous infusion of ilaprazole sodium has similar efficacy and safety as continuous high-dose intravenous infusion of esomeprazole sodium, but the dosage of intermitten regimen is less, the administration is more convenient, and it is worthy of clinical promotion.

Educação permanente em saúde mental: o suicídio na agenda do cuidado dos agentes comunitários de saúde / Permanent education in mental health: the suicide on the health care agenda of community health agents / Educación permanente en salud mental: el suicidio en la agenda del cuidado de los agentes comunitarios de salud

O objetivo desse estudo foi avaliar as atitudes dos Agentes Comunitários de Saúde (ACS) frente ao comportamento suicida antes e depois da capacitação voltada para o manejo de casos com risco suicida. A pesquisa foi desenvolvida no município de Caicó (RN) por ser uma cidade com alto índice de suicídios. Responderam ao Questionário de Atitudes Frente ao Comportamento Suicida (QACS) e a Escala de Atitudes Frente ao Suicídio (EAS) pré/pós-capacitação 38 ACS, com idades entre 27 e 61 anos (M = 38,7, DP = 8,9). Os resultados indicaram que depois da capacitação os ACS apresentaram atitudes mais positivas sobre a capacidade para lidar com os pacientes. As atitudes desfavoráveis em relação ao suicídio anômico foram mais presentes depois da capacitação. Ressalta-se a importância da capacitação dos profissionais com foco no desenvolvimento de atitudes menos moralistas e compassivas.

The objective of this study was to evaluate the attitudes of the Community Health Agents (CHA) in relation to suicidal behavior before and after training aimed at handling cases with suicidal risk. The research was developed in the municipality of Caicó (RN) because it is a city with a high rate of suicides. 38 CHA, aged 27-61 years (M = 38.7, SD = 8.9), answered the Suicide Behavior Attitude Questionnaire (SBAQ) and the Scale of Attitudes Toward Suicide (EAS) Pre/Post training. The results indicated that after the training, the CHA showed more positive attitudes about the ability to deal with patients. The unfavorable attitudes towards anomic suicide were more present after the training.

Effect of Chemotherapy and Predictive Factors for Nausea or Vomiting in Patients with Cancer Receiving Opioid Analgesics for the First Time

Current evidence for the usefulness of prophylactic antiemetic drugs in opioid-induced nausea and vomiting (OINV) in cancer patients receiving opioid analgesics is limited. Further, antiemetic prophylaxis is not considered necessary in the Guideline for Cancer Pain Management by the Japanese Society of Palliative Medicine. However, prevention of side effects such as OINV is important when opioid analgesics are administered for adequate pain management and to maintain adherence. Cancer patients expect us to study factors affecting OINV and effective prophylactic measures for the condition. We retrospectively analyzed electronic records in our hospital. We found that female sex and the use of prophylactic antiemetics, chemotherapeutic agents, and steroids were statistically significant factors associated with opioid-induced nausea, and that female sex and radiation therapy were significant factors associated with opioid-induced vomiting. Especially in females, the frequency of nausea was significantly reduced in the group that received chemotherapy with antiemetics on the same day of receiving opioid analgesics, compared to the groups that did not receive chemotherapy, or that did not receive antiemetics but received chemotherapy. These results suggest that, especially in females, administering chemotherapy along with antiemetics on the same day may be one possible prophylactic measure for OINV.

Usage of ethnomedicine on COVID-19 in China / 中国中药杂志

In December 2019, an outbreak of viral pneumonia began in Wuhan, Hubei Province, which caused the spread of infectious pneumonia to a certain extent in China and neighboring countries and regions, and triggered the epidemic crisis. The coronavirus disease 2019(COVID-19) is an acute respiratory infectious disease listed as a B infectious disease, which is managed according to standards for A infectious disease. Traditional Chinese medicine and integrated traditional Chinese and Western medicine have played an active role in the prevention and control of this epidemic. China's ethnomedicine has recognized infectious diseases since ancient times, and formed a medical system including theory, therapies, formula and herbal medicines for such diseases. Since the outbreak of the COVID-19 epidemic, Tibet Autonomous Region, Qinghai Province, Inner Mongolia Autonomous Region, Xinjiang Uygur Autonomous Region and Chuxiong Autonomous Prefecture of Yunnan, Qiandongnan Autonomous Prefecture of Guizhou have issued the prevention and control programs for COVID-19 using Tibetan, Mongolian, Uygur, Yi and Miao medicines. These programs reflect the wisdom of ethnomedicine in preventing and treating diseases, which have successfully extracted prescriptions and preventive measures for the outbreak of the epidemic from their own medical theories and traditional experiences. In this paper, we summarized and explained the prescriptions and medicinal materials of ethnomedicine in these programs, and the origin of Tibetan medicine prescriptions and Mongolian medicine prescriptions in ancient books were studied. These become the common characteristics of medical prevention and treatment programs for ethnomedicine to formulate therapeutic programs under the guidance of traditional medicine theories, recommend prescriptions and prevention and treatment methods with characteristics of ethnomedicine, and focus on the conve-nience and standardization. However, strengthening the support of science and technology and the popularization to the public, and improving the participation of ethnomedicine in national public health services and the capacity-building to deal with sudden and critical diseases are key contents in the development of ethnomedicine in the future.

Chinese expert consensus on early prevention and intervention of sepsis

Sepsis is currently a major problem and challenge facing the medical community. With rapid development and progress of modern medicine, researchers have put more and more attention on sepsis; meanwhile, the morbidity and mortality of sepsis remains high despite great efforts from experts in various fields. According to updated guidelines, sepsis is defined as life-threatening organ dysfunction caused by a dysregulated host response to infection. Infection is the initial step of sepsis progression, and development from infection to sepsis is a complex pathophysiological process, including pathogen invasion, cytokine release, capillary leakage, microcirculation dysfunction, etc. which finally leads to organ metabolic disorders and functional failure. According to the latest recommended international guidelines of Sepsis 3.0, the presence of infection and SOFA score ≥ 2 are considered as the diagnostic criteria for sepsis, and the 'rescue' measures mainly focus on reversal of organ dysfunction. However, despite nearly two decades of efforts, the 'Save Sepsis Campaign' has not achieved satisfactory results. Emergency medicine is the frontier subject of acute and severe illness which treats patients with acute infections at the earliest. If at this stage, physicians can predict the possibility of sepsis progression from demographic characteristics, localize the pathogen and infection, detect the inflammatory storms by tests of cytokines and evaluate the severity of the infection with more effective clinical scoring system, and then take effective measures to prevent infection from developing into sepsis in high-risk patients, the morbidity and mortality of sepsis in patients with acute infection will be greatly reduced. Based on this situation, Chinese emergency medicine experts proposed the concept of 'preventing and blocking' sepsis, and launched the nationwide 'Preventing Sepsis Campaign in China (PSCC)' nationwide. The main concept is summarized as 'three early and two reduces' which includes early detection, early diagnosis and early intervention during the 'pre-symptomatic' and 'peri-septic' stage in order to reduce the incidence of sepsis and it proposed a new approach for diagnosis and treatment of acute severe infection. This consensus is jointly advocated, discussed and written by four academic associations in the field of emergency medicine and five scholarly publishing organizations. More than 40 experts from fields of emergency medicine, critical care medicine, infectious diseases, pharmacy and laboratory medicine have participated in several rounds of deliberation and finally reached consensus on the criteria of identifying patients with acute infection, taking anti-infective treatments, screening of high-risk patients with sepsis, detection and treatment of inflammatory storm, protection of vascular endothelial cells and the regulation of coagulation function, as well as strategies of liquid support and organ function protection etc. The consensus summarizes the commonly used clinical diagnosis criteria and treatment measures of sepsis both in Western medicine and traditional Chinese medicine for clinicians in order to provide evidence for the diagnosis and treatment of the disease.

Combined Administration of Shinbuto and Boiogito Prevents the Progression of Chronic Kidney Disease with Minimal Proteinuria in the Long-term (Part 2) / 日本東洋医学雑誌

We previously reported that combined administration of shinbuto and boiogito extracts prevented the pro­gression of chronic kidney disease (CKD) over an observation period of 6 months. In the current study, we ex­tended the observation period to 60 months to investigate the long­-term effect of combined drug treatment. The subjects were 24 outpatients with CKD (14 men and 10 women ; mean age, 75.9 years) at the Department of Nephrology of Kagawaken Saiseikai Hospital. Shinbuto extract granules 5 g and boiogito extract granules 5 g were prescribed in two divided doses daily (before breakfast and dinner). Laboratory tests were performed before and 12, 24, 36, 48, and 60 months after drug administration. Although the treatment was discontinued in 14 patients because of reasons including patients' own volition, transfer to other hospitals, and emergence of proteinuria, 10 patients completed 60 months of treatment. Both the mean serum creatinine level (1.78 mg/dL before treatment ; 1.75 mg/dL after 60 months of treatment) and estimated glomerular filtration rate level (30.20 mL/min before treatment ; 34.39 mL/min after 60 months of treatment) did not deteriorate during the study period. Kidney test results persistently and significantly improved compared to the pre-­treatment results in 7 patients in whom the activities of daily living was stabilized. Taken together, we believe that long­-term treatment with shinbuto and boiogito extracts is effective for preventing the progression of CKD, which may be associated with nephrosclerosis, to advanced kidney failure.

Meta-analysis of the Effectiveness of Trolamine for Preventing and Treating Radiation Dermatitis and Quality Evaluation of GRADE Evidence / 中国药房

OBJECTIVE： To evaluate the effectiveness of trolamine for preventing and treating radiation dermatitis （RD） and evidence quality， and to provide reference for clinical use. METHODS： Retrieved from PubMed， Cochrane library， Embase， CNKI， Wanfang and VIP database， randomized controlled trials （RCTs） about trolamine （trial group） versus usual care （control group） for preventing and treating RD were collected. After data extraction， Cochrane bias risk assessment tool 5.0.2 was used to assess the bias risk， and Rev Man 5.3 statistical software was used to perform the Meta-analysis. GRADE evidence quality grading system was used to evaluate the evidence quality of outcome indexes. RESULTS： Seven RCTs were included， involving 782 patients. Results of Meta-analysis showed that there was no statistical significance in total incidence of RD [OR＝0.50， 95％CI （0.23， 1.11）， P＝0.09]， and the incidence of grade Ⅰ RD [OR＝1.32， 95％CI（0.96，1.81）， P＝0.09]， grade Ⅱ RD [OR＝1.07， 95％CI（0.80，1.42）， P＝0.66]， grade Ⅲ RD [OR＝0.69， 95％CI（0.45，1.04）， P＝0.07] or grade Ⅳ RD [OR＝0.43， 95％CI（0.17，1.05）， P＝0.07] between 2 groups. Results of Grade evidence quality evaluation showed that total incidence of RD， and the incidence of grade Ⅱ RD and grade Ⅳ RD were recommended by moderate-level evidence in 2 groups， while the incidence of grade Ⅰ and grade Ⅲ RD were recommended by low-level evidence. CONCLUSIONS： Trolamine is not effective in preventing and treating RD， and can not reduce the incidence of RD.

Análise de custo por evento evitado (COPE) da associação de cobimetinibe e vemurafenibe e outras opções terapêuticas para o tratamento de melanoma metastático com mutação BRAF V600 / Cost of preventing an event (COPE) comparison between the association of cobimetinib and vemurafenib among other treatment options for metastatic melanoma with BRAF V600 Mutation

Objetivo: O melanoma maligno é o tipo de neoplasia de pele com pior prognóstico devido ao seu elevado potencial de gerar metástases e a sua letalidade. Algumas diretrizes internacionais recomendam a combinação de inibidores da via das proteínas quinases BRAF e MEK para o tratamento de melanoma metastático ou irressecável com mutação positiva BRAF V600 em primeira linha. Um estudo demonstrou que, em termos de sobrevida livre de progressão (SLP), a associação de cobimetinibe + vemurafenibe foi a opção terapêutica que proporcionou menor valor de número necessário para tratar (NNT) para o tratamento de melanoma metastático com mutação BRAF V600 em primeira linha. O objetivo desta análise foi de avaliar o custo por evento evitado (COPE) de cobimetinibe em associação com vemurafenibe no tratamento do melanoma irressecável ou metastático, positivos para mutações BRAF V600. Métodos: A análise econômica adotou a perspectiva do Sistema de Saúde Suplementar brasileiro. Os comparadores avaliados foram vemurafenibe monoterapia, dabrafenibe + trametinibe, nivolumabe e ipilimumabe. O COPE foi obtido pelo produto do NNT, baseado na SLP em 12 meses, reportado por Ho et al. e do custo de tratamento considerando custos de aquisição dos medicamentos e manejo de eventos adversos. Resultados: A maior eficiência da associação de cobimetinibe e vemurafenibe foi capaz de proporcionar o menor COPE (R$ 1.204.229) entre todos os comparadores da análise, demonstrando que, com um menor número de pacientes tratados, se observa um caso de sucesso com a terapia combinada, mesmo que esta apresente um custo anual de tratamento superior (R$ 626.477). Conclusão: A associação de cobimetinibe e vemurafenibe foi a mais eficiente em termos de NNT e COPE no melanoma metastático não tratado previamente.

Objective: Melanoma is a type of skin cancer with poor prognosis due to its high potential for metastasis and lethality. Some international guidelines recommend the combination of BRAF and MEK protein kinase pathway inhibitors for the first line treatment of metastatic or unresectable melanoma with BRAF V600 positive mutation. One study demonstrated that in terms of PFS, the combination of cobimetinib + vemurafenib was the first line therapeutic option that provided the lowest number needed to treat (NNT) for BRAF V600 mutated metastatic melanoma. The objective of this analysis was to evaluate the cost of preventing and event (COPE) of cobimetinib in combination with vemurafenib in the treatment of unresectable or metastatic melanoma, positive for BRAF V600 mutations. Methods: The economic analysis adopted the perspective of the Brazilian Supplementary Health System. The comparators evaluated were vemurafenib monotherapy, dabrafenib + trametinib, nivolumabe and ipilimumab. COPE was obtained from the NNT product, based on 12-month progression-free survival (PFS), reported by Ho et al., and the cost of treatment considering medication acquisition costs and adverse event management. Results: The greater efficiency of the combination of cobimetinib and vemurafenib was able to provide the lowest COPE (R$ 1,204,229) among all comparators of the analysis, demonstrating that with a lower number of treated patients a case of success was observed with the combination therapy, even if it presents a higher annual cost of treatment (R$ 626,477). Conclusion: The combination of cobimetinib and vemurafenib was the most efficient in terms of NNT and COPE for previously untreated metastatic melanoma.

“Preventing transform when sickness”——Regulating pre-metastasis niche to prevent tumor metastasis / 中草药

Metastasis is the leading cause of cancer-related death. Pre-metastatic niche formation is the contributing factor of tumor metastasis. Traditional Chinese medicine (TCM) has a curative effect on metastasis and cancer recurrence in clinic. Modern pharmacological studies have shown that China meteria medica (CMM) can inhibit tumor metastasis by affecting tumor secretion, preventing recruitment of immune suppressive cells, and influencing anti-inflammatory polarization of matrix components in certain tissues. The regulation of CMM has the characteristics of multi-target, minor effect, and bidirection, It may play a integrate role with multi-factor and minor effect in regulating tumor-related gene expression or gene-gene combination by influencing regulating tumor-related functional gene networks. This is consistent with the research strategy of taking signal transduction dynamic network as drug target. Therefore, the prevention and treatment of pre-metastatic niche formation via TCM is an effective research strategy. This review summarizes the current research progress on regulating pre-metastasis niche by CMM, and provides a theoretical basis for the future research of TCM to prevent tumor metastasis.

3．Revision of Procedures for Appropriate Management of Revlimid® and Pomalyst® （RevMate®）and Issues for the Future / 薬剤疫学

RevMate®is one of risk minimization activities in Japanese RMPs of Revlimd®and Pomalyst®, of which indications are hematological malignancy including multiple myeloma. This is a proper management procedure approved by Japanese health authorities in order to prevent exposure to pregnant women because these agents are derivatives of thalidomide. RevMate® was revised in 2015 after the discussion in MHLW's Taskforce and its operation started from April 2016. Due to this revision of version 5.0, the manufacture no longer receives the patient name, and this and other information must be managed by the hospital. In addition, with regard to the same objective in the format used in the management procedure（TERMS®）of thalidomide drug products, unification was attempted concerning the name of the format andthe notation of confirmation items. Physician becomes to make judgment to omit explanation of some RevMate® requirements based on the patient's level of their understandings to RevMate®. Periodical survey sheet regarding compliance with RevMate® requirement filled by a patient is to be submitted directly to a physician on his/her visit instead of sending it to the manufacturer by mail under previous procedures. A representative person of the manufacture is required to visit the hospital periodically and confirm filing condition of the survey sheets and compliance check lists of RevMate® for every prescription as well appropriately at the hospital. Furthermore, RevMate® was revised to add clear role description of relevant pharmacists and nurses for in-patients and its strict drug-handling procedures at bedside as version 5.1, as we received four reports from hospitals of medication error of our drug to the another patient in the hospital within 2016. After getting approval of additional indications for Revlimid® from March 2017, RevMate® of version 5.2 started. In the view of implement RevMate® as strict “risk minimization activities” to prevent pregnant women from exposure, we will continue to solve each problem recognized from the actual operation, constantly keep basics in mind by providing necessary training to our employees about thalidomide drug problem etc. In addition, we appreciate the understanding and support from the patient, patient family, Healthcare Professional, etc. involved in this procedure without incompleteness as well as non-compliance with procedures caused by habituation. Including all these, we consider it is important to endeavor as a manufacture continuously in the future.
