Attitudes towards deprescribing and patient-related factors associated with willingness to stop medication among older patients with type 2 diabetes (T2D) in Indonesia: a cross-sectional survey study.

BACKGROUND: Deprescribing of preventive medication is recommended in older patients with polypharmacy, including people with type 2 diabetes (T2D). It seems that many patients in low-middle-income countries are not willing to have their medicines deprescribed. This study aims to assess attitudes of Indonesian patients with T2D towards deprescribing in general and regarding specific cardiometabolic medicines, and factors influencing their willingness to stop medicines. METHODS: Primary care patients with T2D of ≥60 years in Indonesia completed the revised Patients' Attitudes Towards Deprescribing (rPATD) questionnaire. Attitudes in general and for cardiometabolic medicines were reported descriptively. Proportions of patients willing to stop one or more medicines when recommended by different healthcare professionals were compared with Chi-square test. Multiple regression analysis was used to analyse the influence between patient-related factors and the willingness to stop medicines. RESULTS: The survey was completed by 196 participants (median age 69 years, 73% female). The percentages willing to stop medicines were 69, 67, and 41%, when the general practitioner (GP), the specialist, or the pharmacist initiates the process (p-value < 0.001). Higher perceived burden of medicines (p-value = 0.03) and less concerns about stopping (p-value < 0.001) were associated with a higher willingness to stop medicines if proposed by the GP. Patients using multiple glucose-regulating medicines were less willing to stop (p-value = 0.02). Using complementary or alternative medicines was not associated with the willingness to stop. If proposed by their pharmacist, patients without substantial education were more willing to stop than educated patients. CONCLUSIONS: Only two-thirds of older people with T2D in Indonesia were willing to stop one or more of their medicines if the GP or specialist recommended this, and even less when the pharmacist proposed this. Attention should be given to concerns about stopping specific medicines, especially among patients using multiple glucose-lowering medicines, who may be more eligible but were less willing to accept deprescribing.

Investigation of Bone Growth in Additive-Manufactured Pedicle Screw Implant by Using Ti-6Al-4V and Bioactive Glass Powder Composite.

In this study, we optimized the geometry and composition of additive-manufactured pedicle screws. Metal powders of titanium-aluminum-vanadium (Ti-6Al-4V) were mixed with reactive glass-ceramic biomaterials of bioactive glass (BG) powders. To optimize the geometry of pedicle screws, we applied a novel numerical approach to proposing the optimal shape of the healing chamber to promote biological healing. We examined the geometry and composition effects of pedicle screw implants on the interfacial autologous bone attachment and bone graft incorporation through in vivo studies. The addition of an optimal amount of BG to Ti-6Al-4V leads to a lower elastic modulus of the ceramic-metal composite material, effectively reducing the stress-shielding effects. Pedicle screw implants with optimal shape design and made of the composite material of Ti-6Al-4V doped with BG fabricated through additive manufacturing exhibit greater osseointegration and a more rapid bone volume fraction during the fracture healing process 120 days after implantation, per in vivo studies.

Psychometric Measurements of the Adherence to Refills and Medication Scales Among Patients With HIV/AIDS in Indonesia.

OBJECTIVE: This study aimed to conduct a psychometric evaluation of the Adherence to Refills and Medications Scale (ARMS) among patients with HIV/AIDS in Indonesia. METHODS: Psychometric analysis was conducted at 2 hospitals and 7 public health centers at the voluntary counseling and testing clinic. Content validity was measured by assessing the relevance and clarity of each ARMS item. Construct validity was also assessed. Reliability was evaluated using internal consistency and test-retest reliability. RESULTS: This study involved 11 experts in the assessment of the content validity and 240 participants in the estimation of the construct validity. All ARMS items were generally considered easy to understand and relevant, with scale-level content validity index based on the average method (S-CVI/Ave) of 0.9 (>0.78) and item-level content validity index (I-CVI) in the range from 0.5 to 1 for the relevance level and S-CVI/Ave of 0.95 (>0.78) and I-CVI in the range from 0.8 to 1 for the clarity level. Two items (numbers 2 and 3) were revised based on experts' suggestions to enhance comprehension. Confirmatory factor analysis supported 2 subscales: adherence to taking medications and adherence to refilling prescriptions. Good reliability was supported by internal consistency (Cronbach's α 0.793) and test-retest reliability (intraclass correlation coefficient 0.722) for the overall adherence score. CONCLUSIONS: The Indonesian version of ARMS is a valid and reliable medication adherence scale when used in Indonesian patients with HIV/AIDS.

The interventions to improve medication adherence in coronary heart disease patient: A systematic review.

Objective: The clinical outcome and quality of life of CHD patients are greatly influenced by medication adherence. Non-adherence of CHD patients to treatment results in sub-optimal clinical outcomes and increasing costs. This study aims to describe effectiveness of the intervention to improve the medication adherence in CHD patients. Methods: Systematic review methodology was used in this study. Scopus and PubMed were used to search the relevant article systematically. The outcome measured was medication adherence in coronary heart disease patients. Results: Final screening was 31 articles that met the inclusion criteria in this study of 788 articles. Selection processes the article used the PRISMA guideline. Most of the articles (15 articles) use interventions that utilize information technology (IT) as known with m-health in the form of text messages, website, and smartphone-based applications in increasing medication adherence in CHD patients. The non m-health interventions developed are in the form of self-efficacy programs, monitoring and education by health workers or care workers, pharmacy care by clinical pharmacists, and the use of drugs in the form of multi-capsules. The results of most intervention with m-health can improve the medication adherence in CHD patient effectively. Education and motivation program by professional health care and multi-capsules also increasing the medication adherence in the intervention control. There was a decrease of medication adherence in some articles with long time follow-up that can be attention for the professional health care to manage the patient adherent. Conclusion: The medication adherence in CHD patient can be improve by various program. Modification of m-health and non m-health intervention can be resolved to increase the communication, motivation, and knowledge about medication adherence in CHD patients.

Ameliorating Effects of Virgin Coconut Oil (VCO) on Nicotine Dependence and Quality of Life in Smokers.

BACKGROUND: Safer and effective alternatives to manage nicotine dependence are still required. Preliminary studies have shown the potential of virgin coconut oil (VCO) to be used in dependence treatment. OBJECTIVE: to assess the VCO effect administered for 14 days on nicotine dependence and quality of life. METHODS: Forty smoking subjects participated in an open-label, single-center, pre/post-intervention study, and were required to take 15 ml VCO twice daily for 14 days. They were evaluated with the Fagerstrom Test for Nicotine Dependence (FTND) for nicotine dependence intensity and EuroQol-visual analogue scales (EQ VAS) for quality of life. RESULTS: The VCO regimen improved FTND (0.53 points decrease, p<0.05) and EQ-VAS (5.85 points increase p<0.01) scores. Adverse events were all mild. CONCLUSION: Results of the present study suggest that VCO has the potential to be a safe and effective adjunct therapy for the management of nicotine dependence.

Volatile compounds, texture, and color characterization of meatballs made from beef, rat, wild boar, and their mixtures.

The purpose of this research was to characterize the volatile compounds, texture, and color profile of meatballs made from beef, rat, wild boar, and their combinations. Volatile compounds were analyzed using SPME/GC-MS and multivariate data analysis (PCA, PLS-DA). Additionally, several textural features such as hardness, gumminess, chewiness, cohesiveness, and colour (L, a∗, b∗, C, and h) were also analyzed. The findings revealed that texture and color characteristics can only be used to differentiate meatballs based on their raw meat materials when meat adulterants are used in high concentrations (≥50%). PLS-DA analysis of volatile data revealed distinct groupings among various types of meatballs, including meatballs adulterated with rat or wild boar meat at the lowest percentage used in this study (20%). By using VIP and correlation coefficient, the strongest markers in beef, rat, and wild boar meatballs were identified as (Z)-2-amino-5-methyl-benzoic acid, 2-heptenal, and cyclobutanol, respectively. Nonanal was consistently found as a significant marker in the meatballs made from a mixture of beef-rat and beef-wild boar at different ratios. This study demonstrated that the volatile profile of meat is more reliable than physicochemical profiles for developing an analytical tool for quickly identifying undesired meat in meat-derived products.

Tailoring grain sizes of the biodegradable iron-based alloys by pre-additive manufacturing microalloying.

We demonstrated the design of pre-additive manufacturing microalloying elements in tuning the microstructure of iron (Fe)-based alloys for their tunable mechanical properties. We tailored the microalloying stoichiometry of the feedstock to control the grain sizes of the metallic alloy systems. Two specific microalloying stoichiometries were reported, namely biodegradable iron powder with 99.5% purity (BDFe) and that with 98.5% (BDFe-Mo). Compared with the BDFe, the BDFe-Mo powder was found to have lower coefficient of thermal expansion (CTE) value and better oxidation resistance during consecutive heating and cooling cycles. The selective laser melting (SLM)-built BDFe-Mo exhibited high ultimate tensile strength (UTS) of 1200 MPa and fair elongation of 13.5%, while the SLM-built BDFe alloy revealed a much lower UTS of 495 MPa and a relatively better elongation of 17.5%, indicating the strength enhancement compared with the other biodegradable systems. Such an enhanced mechanical behavior in the BDFe-Mo was assigned to the dominant mechanism of ferrite grain refinement coupled with precipitate strengthening. Our findings suggest the tunability of outstanding strength-ductility combination by tailoring the pre-additive manufacturing microalloying elements with their proper concentrations.

Ameliorating Effects of Four-Week Fiber-Multivitamin Combination Treatment on Low-Density Lipoprotein Cholesterol, Total Cholesterol, and Apolipoprotein B Profiles in Hypercholesterolemic Participants.

Hyperlipidemia is one of the leading causes of death and requires lipid-lowering treatment to reduce morbidity and mortality. Effective and safe alternative and adjunctive therapies could be beneficial for patients with hyperlipidemia. To assess the effect of a fiber-multivitamin combination product on the lipid parameters low-density lipoprotein cholesterol (LDL-c), high-density lipoprotein cholesterol (HDL-c), total cholesterol (TC), triglyceride (TG), and apolipoprotein B (Apo B) in patients with hypercholesterolemia, we conducted a double-blind, randomized, parallel-group study. Forty-one out of 50 randomized hypercholesterolemic participants recruited between August 2016 and March 2018 completed the trial. The participants were assigned to receive either test product (treatment group, n = 20) or placebo (placebo group, n = 21) for 4 weeks following a 6-week dietary intervention (based on education from a dietitian) run-in period. The primary outcome was LDL-c levels and the secondary outcomes were HDL-c, TC, TG, and Apo B levels. All of the outcomes were measured at baseline and week 4 after the completion of run-in period. Participants in both groups had similar LDL-c levels (142 ± 15.7 vs. 143 ± 19.3 mg/dL). After 4 weeks of exposure to test product, participants in the treatment group demonstrated a 17.25 ± 22.26 reduction in LDL-c (p < .05 vs. placebo). This improvement in LDL-c was accompanied by amelioration in TC and Apo B levels, without any detrimental effects on HDL and TG concentration. Results of the present study suggest that fiber-vitamin combination has potential to be used as an adjunct therapy for the management of hypercholesterolemia.

Deformations of Ti-6Al-4V additive-manufacturing-induced isotropic and anisotropic columnar structures: Insitu measurements and underlying mechanisms.

The deformations of isotropic and anisotropic Ti-6Al-4V columnar structures fabricated by additive manufacturing were extensively examined. The distinct texture and microstructure distributions were characterised. In situ X-ray diffraction measurements show different lattice activities resulting from the different microstructure distributions. Spatially resolved mapping revealed manufacturing-induced crystallite-orientation distributions that determine the deformation mechanisms. We propose a self-consistent model to correlate the multi-scale characteristics, from the anisotropic-texture-distribution microstructure to the bulk mechanical properties. We determined that basal and pyramidal slip activities were activated by tension deformation. The underlying additive-manufacturing-induced crystal plasticity plays a major role. We find that the texture development of the columnar structures and the distribution of crystallite orientation achieved by different processing conditions during additive manufacturing have important effects on the mechanical properties. The dominant deformation mode for the anisotropic Ti-6Al-4V columnar structure is basal slip, and that for the isotropic Ti-6Al-4V columnar structure is pyramidal slip. The difference may be important for determining the fatigue behaviour.

Prevalence of Adverse Drug Reactions in CAD STEMI Patients Treated in the Cardiac Intensive Care Unit at the Public Hospital in Bandung, Indonesia.

Adverse drug reactions (ADRs) are associated with morbidity, mortality, and can contribute to increased healthcare costs. This study was conducted to identify the occurence, types, and management of ADRs, as well as analyze the causal relationship, severity, and preventability of ADRs. The study was observational analysis with concurrent data collection from patients with Coronary Artery Disease-ST segment Elevation Myocardial Infarction (CAD-STEMI) treated in the Cardiac Intensive Care Unit (CICU) at a hospital in Bandung Indonesia, during the period of December 2013 to March 2014. The occurence of identified ADRs was assessed using the probability scale of Naranjo, while the severity by the scale of Hartwig and their preventability was evaluated using the scale of Schumock-Thornton. 49 ADRs were identified in 29 patients. Organ systems most affected by the ADRs were the cardiovascular and body electrolyte, each accounting for 20.41%. The hematology and gastrointestinal systems each contributed 18.37% to ADR occurrences. The causal relationship was mostly classified as "probable," accounting for 69.39%. With regard to severity, most ADRs were classified as "moderate" at level 3, contributing to 53.06% of the occurence. In terms of preventability, most of the ADRs fell into the "non-preventable" category (79.59%). The most widely applied ADRs management was administration of an antidote or other treatments (40.82%). Further analysis revealed that the average number of drug types and duration of hospitalization significantly affected the presence of ADRs. Taken together, most patients with CAD STEMI treated in the CICU of the studied hospital experienced non-preventable ADRs and were treated with antidote or other treatments.
