Is the combined auriculotherapy approach superior to magneto-auriculotherapy alone in aging males with lower urinary tract symptoms? A randomized controlled trial.

OBJECTIVES: The negative impact of lower urinary tract symptoms (LUTS) on affected males is substantial. This study aims to assess whether a combined auriculotherapy (AT) using laser AT (LAT) and magneto-AT (MAT) is more effective than using MAT alone or placebo for managing LUTS of aging males.Methods: A randomized controlled, double-blinded trial was conducted. Sixty-two aging males with moderate or severe LUTS symptoms were randomly allocated into groups: Group 1, placebo LAT plus placebo MAT (n = 20); Group 2, combined AT approach using LAT plus MAT (n = 20); and Group 3, placebo LAT followed by MAT (n = 22). Six ear acupoints assumed to be suitable for alleviating LUTS were used. The total treatment period was 4 weeks, with follow-up visits till 3 months. Generalized estimating equations model was used for the examination of the interactions among the groups over time.Results: A combined AT approach exhibited a stronger treatment effect in relieving voiding problems, improving the peak urinary flow rate, and reducing the post-void residual urine than the placebo group or MAT alone.Conclusions: This study demonstrates that the AT protocol used in this study for aging males with LUTS is feasible and can be adopted in future study of increased scale.

Epidemiological investigation on hand hygiene knowledge and behaviour: a cross-sectional study on gender disparity.

BACKGROUND: The hand hygiene (HH) behaviour of the general public and its effect on illnesses are issues of growing importance. Gender is associated with HH behaviour. HH efficiency is a combination of washing efficiency and hand drying, but information about the knowledge level and HH behaviour of the general public is relatively limited. The findings of this cross-sectional study can substantially contribute to the understanding on the knowledge gap and public behaviour towards HH, thereby providing information on gender-specific health promotion activities and campaigns to improve HH compliance. METHODS: An epidemiological investigation by using a cross-sectional study design on the general public was conducted either via an online platform (SurveyMonkey) or paper-and-pen methods. The hand-washing and -drying questionnaire was used for data collection. RESULTS: A total of 815 valid questionnaires were collected. Majority of the respondents can differentiate the diseases that can or cannot be transmitted with poor HH, but the HH knowledge of the respondents was relatively inadequate. The female respondents had a significantly better HH knowledge than male respondents. The multiple regression analysis results also indicated that females had a significantly higher knowledge score by 0.288 towards HH than males after adjusting for age and education level. Although the majority of the respondents indicated that they performed hand cleaning under different specific situations, they admitted only using water instead of washing their hands with soap. More males than females dried their hands on their own clothing, whereas more females dried their hands through air evaporation. The average time of using warm hand dryers was generally inadequate amongst the respondents. CONCLUSIONS: Being a female, middle-aged and having tertiary education level are protective factors to improve HH knowledge. Misconceptions related to the concepts associated with HH were noted amongst the public. Self-reported practice on hand drying methods indicated that additional education was needed. The findings of this study can provide information on gender-specific health promotion activities and creative campaigns to achieve sustained improvement in HH practices.

The public washroom - friend or foe? An observational study of washroom cleanliness combined with microbiological investigation of hand hygiene facilities.

Background: Many people use handwashing and hand-drying facilities in public washrooms under the impression that these amenities are hygienic. However, such facilities may be potential sites for the transmission of pathogenic bacteria. This study aimed to examine the hygiene facilities provided including handwashing and hand-drying facilities in public washrooms. Total bacterial counts and species identification were determined for hand-drying facilities. Antimicrobial susceptibilities were performed. Methods: The bacterial contamination levels of 55 public washrooms ranging in category from low class communities to high end establishments, were examined. The hygienic environment and facilities of the washrooms were analysed using an electronic checklist to facilitate immediate data entry. Pre-moistened sterile swabs were used to collect samples from areas around the outlet of paper towel dispensers, air outlet of air dryers, exit door handles and paper towels in the washrooms. Total bacterial counts were performed and isolates identified using matrix-assisted laser desorption ionisation time-of-flight mass spectrometry. Antimicrobial susceptibility was determined by disk diffusion. Results: The high and middle-income categories washrooms generally had cleaner facilities and environment followed by those in low categories. Fifty-two bacterial species were identified from the 55 investigated washrooms. Over 97% of the pathogenic Staphylococcus spp. tested were resistant to at least one first-line antimicrobial therapeutic agent, including penicillin, cefoxitin, erythromycin, co-trimoxazole, clindamycin and gentamicin, and 22.6% demonstrated co-resistance to at least three antimicrobial agents, with co-resistance to penicillin, erythromycin and clindamycin being the most common. Conclusion: Our findings suggest that hand-drying facilities in public washrooms can act as reservoirs of drug-resistant bacteria. The importance of frequent cleaning and maintenance of public washrooms to promote safe hand hygiene practices for the public are emphasised.

Using auriculotherapy for osteoarthritic knee among elders: a double-blinded randomised feasibility study.

BACKGROUND: Osteoarthritic knee (OA knee) is a common condition in the elderly. Exploration of non-invasive complementary therapies for OA knee is warranted given the limitations of pharmacologic therapies. Auriculotherapy (AT) is a therapeutic method in which specific points on the auricle are stimulated to treat various disorders of the body, and the therapeutic value and synergistic effect of laser auriculotherapy (LAT) when combined with magneto-auriculotherapy (MAT) merits further investigation. METHODS: This study adopted a double-blinded four-arm randomized placebo design. The aims of study are (1) to assess the feasibility of AT among elders with OA knee in a future large-scale study, including the use of blinding in subjects and evaluators, acceptance of treatment protocol, and estimating the effect size and attrition rate; and (2) to evaluate the preliminary effect of AT in elders with OA knee. Subjects were randomly divided into four groups with different modes of AT with/without placebo objects. A total of 43 subjects completed the 6-week intervention and post-assessment. Assessments included a numerical rating scale of pain (NRS), the timed-up-and-go test (TUGT), and standard goniometer measurements during knee flexion and extension, Kruskal-Wallis test was used to evaluate differences among groups, and Wilcoxon sign-ranked test for examining within-group comparison. RESULTS: Preliminary results indicated the absence of differences in the NRS, TUGT, and active/passive knee flexion and extension at baseline, as well as post-therapy, between the four groups. Even though the differences of these parameters between groups were not significant, the relative differences of NRS and TUGT in subjects who received combined MAT plus LAT were higher than those treated with MAT or LAT alone, or the placebo group. Four of the six parameters demonstrated significant within group differences in subjects who received MAT and/or LAT, whereas no significant differences were found in the placebo group. CONCLUSION: This study demonstrates that the AT protocol adopted in this study for elders with OA knee is feasible and could be applied in future larger-scale study. Larger sample size should be considered in a future trial to determine the causal relationship between treatment and effect. TRIAL REGISTRATION: ClinicalTrials.gov: NCT02352636 .

The role of turmerones on curcumin transportation and P-glycoprotein activities in intestinal Caco-2 cells.

The rhizome of Curcuma longa (turmeric) is often used in Asia as a spice and as a medicine. Its most well-studied component, curcumin, has been shown to exhibit poor bioavailability in animal studies and clinical trials. We hypothesized that the presence of lipophilic components (e.g., turmerones) in turmeric extract would affect the absorption of curcumin. The effects of turmerones on curcumin transport were evaluated in human intestinal epithelial Caco-2 cells. The roles of turmerones on P-glycoprotein (P-gp) activities and mRNA expression were also evaluated. Results showed that in the presence of α- and aromatic turmerones, the amount of curcumin transported into the Caco-2 cells in 2 hours was significantly increased. α-Turmerone and verapamil (a P-gp inhibitor) significantly inhibited the efflux of rhodamine-123 and digoxin (i.e., inhibited the activity of P-gp). It is interesting that aromatic turmerone significantly increased the rhodamine-123 efflux and P-gp (MDR1 gene) mRNA expression levels. The effects of α- and aromatic turmerones on curcumin transport as well as P-gp activities were shown here for the first time. The presence of turmerones did affect the absorption of curcumin in vitro. These findings suggest the potential use of turmeric extract (including curcumin and turmerones), rather than curcumin alone, for treating diseases.

Immunostimulatory activities of polysaccharide extract isolated from Curcuma longa.

Several curcuminoids and sesquiterpenoids isolated from Curcuma longa (CL) have been shown to have many pharmacological activities. In the present study, the immunomodulatory activities of the polar fractions of CL hot water extracts were investigated using human peripheral blood mononuclear cells (PBMC). Our results showed that the high polarity fraction of the hot water extract exhibited stimulatory effects on PBMC proliferation as shown in [methyl-(3)H]-thymidine incorporation assay. In an attempt to isolate the active components responsible for the activities, further partition with ethyl acetate, n-butanol and ethanol, progressively were performed. The cytokine productions (TGF-beta, TNF-alpha, GM-CSF, IL-1alpha, IL-5, IL-6, IL-8, IL-10, IL-13, etc.) have been modulated by a polysaccharide-enriched fraction as shown in ELISA and cytokine protein array. The proportion of CD14 positive stained PBMC was increased by such fraction. The composition of monosaccharide of the active fraction has been determined by GC-MS and gel permeation chromatography. The immunostimulatory effects of C. longa polysaccharides on PBMC were shown for the first time. The findings revealed the potential use of C. longa crude extract (containing curcuminoids and polysaccharides) as an adjuvant supplement for cancer patients, whose immune activities were suppressed during chemotherapies.
