Introduction: The diabetes mellitus-periodontitis relationship has advocated several strategic management approaches on effective glycaemic control and oral health improvement for diabetic patients and periodontitis patients with diabetes. We aimed to identify the challenges of providing health education to patients with diabetes and/or periodontitis among healthcare professionals and needs for an integrated nutritionoral health education module. Methods: This study involved semi-structure in-depth interview with fifteen healthcare professionals from a training hospital focused on: (i) the existing issues and challenges encountered while managing patients for their nutrition and care and (ii) issues related to the current practice among healthcare professionals. Details pertaining to the participants’ verbal and non-verbal responses were recorded, transcribed ad verbatim and analysed using themes codes. Results: Patients’ attitude and behaviour, language barriers and prioritising time were found as the common problems with patients, while limited knowledge on the relationship between diabetes-periodontitis, limited availability of appropriate and cultural-based health educational tools, lack of inter-professional multidisciplinary collaboration in managing patients, and constrains in time as well as costly therapy were common issues in the current practice. Conclusions: Cost-effective efforts must be focused on overcoming these issues besides emphasizing the needs on developing an integrated module to achieve better management outcomes.

Objective The objective of this study was to test the effectiveness of an audit programme for dyslipidaemia management in a primary care setting in Macau.Design A quality improvement study based on an evaluation of a before-after intervention trial was conducted in 2017–2018. Interventions comprising feedback from an audit, general practitioner (GP) training via interactive workshops and one-on-one case discussions were implemented. The primary outcome measure was the proportion of patients with reasonable management of dyslipidaemia, and the secondary outcome measure was the proportion of patients with low-density lipoprotein cholesterol (LDL-C) meeting the target recommended by the Adult Treatment Panel III guidelines.Setting This study was conducted at the Sao Lourenco Health Center, one of the health centres in the Macau primary care system; this centre provides primary care services to one-tenth of the residents of Macau.Participants All GPs who worked in the Sao Lourenco Health Center participated in the study. We systematically reviewed 100 patient records from each participating physician’s patient list. In total, 1200 and 1100 patient records were reviewed before and after the intervention, respectively.Results At baseline, 390 (43.5%) patients were eligible for statin therapy, while 411 (47.7%) patients were eligible for statin therapy in the reaudit group (p=0.08). After intervention, the proportion of patients with reasonable management of dyslipidaemia increased from 83.9% to 88.5% (p=0.005), and the proportion of eligible patients with LDL-C levels meeting the target increased from 55.1% to 65% (p=0.004).Conclusions The audits and feedback significantly improved dyslipidaemia management in the Macau primary care setting.

Abstract Background Human Disabled-2 (DAB2), is a multi-function signalling molecule that it is frequently down-regulated in human cancers. We aimed to investigate the possible tumour suppressor effect of DAB2 in nasopharyngeal carcinoma (NPC). Methods We studied the expression of DAB2 in NPC cell lines, xenografts and primary tumour samples. The status of promoter methylation was assessed by methylation specific PCR and bisulfite sequencing. The functional role of DAB2 in NPC was investigated by re-introducing DAB2 expression into NPC cell line C666-1. Results Decrease or absent of DAB2 transcript was observed in NPC cell lines and xenografts. Loss of DAB2 protein expression was seen in 72% (33/46) of primary NPC as demonstrated by immunohistochemistry. Aberrant DAB2 promoter methylation was detected in 65.2% (30/46) of primary NPC samples by methylation specific PCR. Treatment of the DAB2 negative NPC cell line C666-1 with 5-aza-2'-deoxycytidine resulted in restoration of DAB2 expression in a dose-dependent manner. Overexpression of DAB2 in NPC cell line C666-1 resulted in reduced growth rate and 35% reduction in anchorage-dependent colony formation, and inhibition of serum-induced c-Fos expression compared to vector-transfected controls. Over expression of DAB2 resulted in alterations of multiple pathways as demonstrated by expression profiling and functional network analysis, which confirmed the role of DAB2 as an adaptor molecule involved in multiple receptor-mediated signalling pathways. Conclusions We report the frequent down regulation of DAB2 in NPC and the promoter hypermethylation contributes to the loss of expression of DAB2. This is the first study demonstrating frequent DAB2 promoter hypermethylation in human cancer. Our functional studies support the putative tumour suppressor effect of DAB2 in NPC cells.

Background: A good understanding of the bi-directional relationship between diabetes and periodontitis is essential to ensure the successful management of both diseases. This study aimed to develop and evaluate an integrated diabetes-periodontitis nutrition and health education module., Methods: The module was developed as an iterative and review process by five experts in nutrition and dietetics, periodontics, and dental public health. It consisted of three phases: (i) needs assessment on module contents and characteristics, (ii) module development and (iii) module evaluation by experts. Twelve healthcare professionals aged between 30 and 53 years (average 13.5 years of working experience) validated the module contents and its comprehensibility using the Patient Education Materials Assessment Tool for printable materials (PEMAT-P) and audio-visual materials (PEMAT-A/V). Scores of 0 (disagree) or 1 (agree) were given for sets of understandability and actionability statements and presented as a total percentage., Results: Seventeen infographic-flip charts and 13 short-videos were developed in the Malay language and grouped into four topics: (i) Introduction to Diabetes and Periodontitis, (ii) Diabetes and Periodontitis Care, (iii) Lifestyle Modification, and (iv) Myths and Facts. Flip charts were rated between 76-100% for understandability and 80-100% for actionability, while videos rated between 90-100% for understandability and 100% for actionability, respectively., Conclusion: Overall, the newly developed module ranked high median scores for understandability and actionability. This finding reflects positive acceptance of the integrated module among the various healthcare professionals involved in managing patients with diabetes and periodontitis.

Background: In accordance with current guidelines, proton pump inhibitors (PPIs) are now generally prescribed as a protective co-medication in patients taking non-steroidal anti-inflammatory drugs (NSAIDs) or low-dose acetylsalicylic acid (LDASA). However, less attention is paid to the corresponding discontinuation of a PPI after cessation of NSAID or LDASA treatment., Objective: The aim of this study was to assess the extent of inappropriate PPI use, as the proportion of patients who started a PPI as a protective co-medication but continued using these drugs after cessation of NSAID and LDASA treatment. We also sought to estimate the potential cost savings and effect gains of discontinuing inappropriate PPI use and the resulting decrease in adverse effects and their detrimental consequences., Methods: Pharmacy dispensing data were used to map inappropriate PPI use in 2014 for community-dwelling patients. Strategies with or without PPI continuation were compared in the cost-utility analysis for a time horizon of 5 years from a healthcare perspective. Subsequently, incremental costs and effects (quality-adjusted life-years) were estimated with a Markov model., Results: Related to NSAID and LDASA treatment, 11.0% and 5%, respectively, of the PPI users were found to inappropriately continue PPI co-treatment. Discontinuation in 71- to 80-year-old patients suggested cost savings of €170.46 (95% confidence interval 75-282) at a 0.003 (95% confidence interval 0.001-0.005) quality-adjusted life-year increase. The total budget impact of stopping inappropriate PPI use related to NSAID/LDASA treatment in the Netherlands would amount to almost €1,050,000 after 1 year. Correspondingly, successful interventions to stop a patient's inappropriate use would cost up to €29 and probably would pay for themselves in the following years., Conclusions: A substantial number of patients inappropriately continue to use a PPI after cessation of NSAID or LDASA treatment. Because adverse effects and their detrimental consequences are avoided, interventions to stop inappropriate PPI use, particularly in older patients, are likely to pay for themselves.

Background: Inappropriate drug use is a frequent problem in older patients and associated with adverse clinical outcomes and an important determinant of geriatric problems. Clinical medication reviews (CMR) may reduce inappropriate drug use., Objective: The aim of this study is to investigate the effectiveness of CMR on quality of life (QoL) and geriatric problems in comparison with usual care in older patients with geriatric problems in the general practice., Methods: We performed a cluster randomised controlled trial in 22 Dutch general practices. Patients of ≥65 years were eligible if they newly presented with pre-specified geriatric symptoms in general practice and the chronic use of ≥1 prescribed drug. The intervention consisted of CMRs which were prepared by an independent expert team and discussed with the patient by the general practitioner. Primary outcomes: QoL and the presence of self-reported geriatric problems after a follow-up period of 6 months., Results: 518 patients were included. No significant differences between the intervention and control group and over time were found for QoL, geriatric problems, satisfaction with medication and self-reported medication adherence. After 6 months the percentage of solved Drug Related Problems (DRPs) was significantly higher in the intervention group compared to the control group [B 22.6 (95%CI 14.1-31.1), P < 0.001]., Conclusion: The study intervention did not influence QoL and geriatric problems. The higher percentage of solved DRPs in the intervention group did not result in effects on the patient's health. CMRs on a large scale seem not meaningful and should be reconsidered., (© The Author 2017. Published by Oxford University Press. All rights reserved.

Purpose: The present study aimed to assess the cost effectiveness of concomitant proton pump inhibitor (PPI) treatment in low-dose acetylsalicylic acid (LDASA) users at risk of upper gastrointestinal (UGI) adverse effects as compared with no PPI co-medication with attention to the age-dependent influence of PPI-induced adverse effects., Methods: We used a Markov model to compare the strategy of PPI co-medication with no PPI co-medication in older LDASA users at risk of UGI adverse effects. As PPIs reduce the risk of UGI bleeding and dyspepsia, these risk factors were modelled together with PPI adverse effects for LDASA users 60-69, 70-79 (base case) and 80 years and older. Incremental cost-utility ratios (ICURs) were calculated as cost per quality-adjusted life-year (QALY) gained per age category. Furthermore, a budget impact analysis assessed the expected changes in expenditure of the Dutch healthcare system following the adoption of PPI co-treatment in all LDASA users potentially at risk of UGI adverse effects., Results: PPI co-treatment of 70- to 79-year-old LDASA users, as compared with no PPI, resulted in incremental costs of €100.51 at incremental effects of 0.007 QALYs with an ICUR of €14,671/QALY. ICURs for 60- to 69-year-old LDASA users were €13,264/QALY and €64,121/QALY for patients 80 years and older. Initiation of PPI co-treatment for all Dutch LDASA users of 60 years and older at risk of UGI adverse effects but not prescribed a PPI (19%) would have cost €1,280,478 in the first year (year 2013 values)., Conclusions: PPI co-medication in LDASA users at risk of UGI adverse effects is generally cost effective. However, this strategy becomes less cost effective with higher age, particularly in patients aged 80 years and older, mainly due to the increased risks of PPI-induced adverse effects.

Background: Knowledge of drug-related problems (DRPs) identified in the medication of home-dwelling elderly patients with polypharmacy has been based predominantly on medication reviews conducted in research settings rather than in daily practice., Objective: To evaluate the prevalence of DRPs identified by means of a clinical medication review (CMR) and the implementation rate of proposed interventions in a large group of older patients with polypharmacy in the daily practice of community pharmacies., Setting: 318 Dutch community pharmacies., Method: A cross-sectional study based on CMR-data of 3807 older patients (≥65 years) with polypharmacy (≥5 drugs) completed between January and August 2012. Data were extracted from community pharmacists' databases and entailed: year of birth, gender, dispensing data, number and nature of identified DRPs, consultations performed, proposed and implemented interventions. Main outcome measure Prevalence of DRPs, drug classes involved in overtreatment and undertreatment, and proposed and implemented interventions., Results: A median of two DRPs (interquartile range 1-4; mean 3.0) was identified per patient. The DRP-categories overtreatment (25.5 %) and undertreatment (15.9 %) were found most frequently. 46.2 % of the proposed interventions to solve DRPs were implemented as proposed, in 22.4 % of cases, the intervention differed from the proposal. In 31.3 % of cases no intervention was implemented., Conclusion: By conducting a CMR community pharmacists identified a median of two DRPs in older patients with polypharmacy. Overtreatment and undertreatment accounted for 41.4 % of the DRPs identified. In dealing with DRPs, pharmacists proposed a variety of interventions of which the majority (69.9 %) was either implemented or led to alternative interventions. A set of explicit criteria should be applied during a CMR to solve and prevent DRPs.

Objective: To investigate the nature and prevalence of drug related problems (DRPs) in older patients with polypharmacy identified by community pharmacists in daily practice through means of a clinical medication review (CMR) and assess the implementation rate of proposed interventions to solve DRPs., Design: A cross-sectional study METHOD: We analysed the CMR data of 3,807 older patients (≥ 65 years) with polypharmacy (≥ 5 drugs) completed in January-August 2012. Using the "Service Apotheek Medicatie Review Tool" (SAMRT, Service Pharmacy Medication Review Tool), pharmacists in 258 community pharmacies registered the patients' year of birth, gender, dispensing data, DRPs, and proposed and implemented interventions., Results: Pharmacists identified a median of two DRPs (interquartile range 1-4; mean 3.0) per patient. The DRP categories overtreatment (25.5 %) and undertreatment (15.9 %) were found to occur most frequently. On average, 46.2 % of the proposed interventions to address DRPs were implemented as proposed. In 22.4 % of cases the intervention differed from the proposal, whereas in 31.3 % of cases no intervention was implemented., Conclusion: In daily practice, community pharmacists identified a mean of three DRPs in older patients with polypharmacy, a number comparable to that found in controlled studies. Over- or undertreatment caused nearly half of the identified DRPs. The majority (69.9%) of the proposed interventions led to an intervention for the patient.

Gas-liquid chromatographic analyses of three complete series of synthetic positional isomers of methyl thia, selena, and tellura laurate analogs were carried on a nonpolar (SE-30) and a polar (SP-2330) stationary phase. The average ECL (equivalent chain length) values of the thia, selena, and tellura laurate on SE-30 stationary phase were 13.8, 14.8, and 15.7, respectively, while on SP-2330 the average values for the same series were 17.1, 19.0, and 19.1, respectively. Positional isomers with the heteroatom at the 2-position exhibited the lowest ECL values, while those with the heteroatom at the omega-1 position gave the highest ECL values and were readily separated from the other positional isomers of the same series of analogs by this technique.
