The association between halitosis and periodontitis: a systematic review and meta-analysis.

OBJECTIVES: The purpose of this systemic review and meta-analysis was to explore the association between halitosis and periodontitis in observational studies. MATERIALS AND METHODS: A systematic search covered PubMed, Web of Science, Embase, Scopus, and Cochrane Library until August 18, 2023. Nine observational studies (585 cases, 1591 controls) were analyzed using Stata 17, with odds ratios (ORs) and 95% confidence intervals (CIs). Subgroup analyses considered halitosis assessment methods. RESULTS: The review found a positive association between halitosis and periodontitis. Significant differences were observed with organoleptic test (OR = 4.05, 95% CI: 1.76, 9.30, p < 0.01) and volatile sulfur compound readings (OR = 4.52, 95% CI: 1.89, 10.83, p < 0.01). CONCLUSIONS: A positive association was observed between halitosis and periodontitis, supported by significant differences in both organoleptic and volatile sulfur compound readings. However, conclusive findings are limited by statistical heterogeneity, emphasizing the need for additional research. CLINICAL RELEVANCE: Understanding the halitosis and periodontitis association is clinically significant, informing potential interventions for improved oral health. Further research is vital to refine understanding and guide effective clinical strategies, acknowledging the limitations in current findings.

Implications of sleep disorders for periodontitis.

PURPOSE: Periodontitis is a chronic inflammatory disease caused by multi-factors. Sleep is a natural physiologic process, and the sleep duration, quality, and patterns might be associated with periodontitis. Meanwhile, periodontitis might in turn induce systemic inflammation and thus impact sleep in different ways as well. METHODS: To investigate the bidirectional relationship between sleep disorder and periodontitis, a literature search was conducted to reveal the interaction and possible mechanism between these two diseases. RESULTS: The results show that sleep disorders can affect the progression of periodontitis via some pathomechanisms, and periodontitis also has a reverse impact on sleep. CONCLUSION: Although the epidemiologic and clinical trials found the possible associations between sleep disorder and periodontitis, their relationship is still not that explicit. Further studies are warranted to shed light on them, to improve preventive health care.

Framework of family doctors′contract-based service system and its practice in Zhejiang province / 中华医院管理杂志

The control handles( including financing, provider payment, organization, regulation and behavior) proposed by World Bank in health policy research as the basic framework,and the nature and positioning of family doctors′ contract-based service as the precondition, we recommended the system framework of such a mechanism, comprising one contract, three regulations, five control handles and seven supporting policies. Such a framework can serve as the cornerstone for family doctors′ contract-based service experiment in Zhejiang province for the sake of hierarchical medical system.

Study of occupational stability of general practitioners tailor-made for rural communities in Zhejiang ;province / 中华医院管理杂志

Objective To examine the occupational stability,training needs and capacity building requirements of the general practitioners purposely trained to work in rural communities,for improvement of policies regarding their training and issues related. Methods There counties were selected by stratified random sampling, where general practitioners graduated from such training completed an anonymous questionnaire. Focus group interviews were made to officials of the local Health and Family Planning Commission,those of primary healthcare institutions,and general practitioners themselves. Results The of the 190 valid questionnaires recovered, male accounted for 34. 2% and female 65. 8%. These general practitioners were mostly satisfied with their working environment, social status, work stress and job achievement,yet with lower satisfaction with their salary and availability of medical devices. Consideration of resignation was reported by only 5. 3% of them,with more males than females. As high as 63. 2% of them prefer to work in hospitals of county level. 91. 1% of them held it as necessary to participate in standard resident training,and 98. 4% held it as necessary to have on-job training. 94. 7% of them have participated in further education to gain a bachelor degree in medicine. Conclusions These doctors were found with high stability to work in rural communities and low turnover intention. Further studies are required to encourage these general practitioners to serve rural communities in a long term, and to improve the standard resident training mechanism,and their career development.

Analysis of the economic performance in the performance-based reform at primary medical institutions in Zhejiang province / 中华医院管理杂志

Objective To explore the economic performance after the performance‐based reform at primary medical institutions in Zhejiang Province and put forward measures for improving primary medical services .Methods Questionnaire investigation was conducted among 84 primary medical institutions with staff over 20 .The financial statements of these institutions during 2009‐2014 were collected and studied as well .Results The average outpatients and emergency patients in 2014 increased 113.3% than that in 2009 .The total usage times of laboratory tests and other auxiliary examinations also increased(55.7% and 103.1% ,respectively ) ,yet with a decrease of inpatients.Moreover ,the proportion of income from traditional Chinese medicine (TCM )in gross income increased from 9.39% in 2009 to 17.14% in 2014 .The cost‐profit ratio of TCM drugs at half of such institutions exceeded 120% . Conclusions The performance‐based reform has motivated medical staffs of primary medical institutions and effectively vitalized such institutions.Rules and regulations of these institutions require further improvement .

Discovery of Overcoating Metal Oxides on Photoelectrode for Water Splitting by Automated Screening.

We applied an automated semiconductor synthesis and screen system to discover overcoating film materials and optimize coating conditions on the BiVO4/WO3 composite photoelectrode to enhance stability and photocurrent. Thirteen metallic elements for overcoating oxides were examined with various coating amounts. The stability of the BiVO4/WO3 photoelectrode in a highly concentrated carbonate electrolyte aqueous solution was significantly improved by overcoating with Ta2O5 film, which was amorphous and porous when calcined at 550 °C. The photocurrent for the water oxidation reaction was only minimally inhibited by the presence of the Ta2O5 film on the BiVO4/WO3 photoelectrode.

Functional orientation of township hospitals in developed areas in China / 中华医院管理杂志

Objective To explore the functional orientation of township hospitals in developed areas to achieve goals of the ongoing health reform.Methods Two rounds of Delphi consultation was made among 18 experts from around the country to learn the degree of importance of every function.Results The experts' average seniority of service in their fields was 23.28±10.41 years.The positivity coefficients of the two-round consultation were 100％.Kendall' S coefficients of the two-round consultation were 0.226 and 0.265 (p＜0.01).These data are of statistical importance,suggesting consensus among these experts and the consultation meeting the needs of forecast.In these consultation,seven class-1 functions and and 27 class-2 functions were determined.Medical services and public health services account for similar proportion of work of township hospitals.Conclusion The functional orientation was feasible and forward looking,for reference of township hospitals in developed areas.
