AIM: To explore pain relief interventions used by older people with chronic pain in Hong Kong. The frequency and perceived effectiveness of non-prescription measures were also explored. BACKGROUND: With increasing life expectancy, the incidence of chronic illness and chronic pain also increases. Chronic pain robs older people of their quality of life. DESIGN: This was a descriptive qualitative study. RESULTS: Forty-four older people (37 female and seven male) who were residents of a nursing home in Hong Kong took part in this study. Their ages ranged from 65 to 82 years, median age was 75 years. Almost 80% had experienced moderate to severe pain during the previous three months. The most common sites of pain were muscles and joints; 35% of subjects reported continuous pain, 27% reported pain associated with activities of daily living, and 38% reported pain during exercise but not at rest. Only a few of the study group had taken prescribed medication to relieve pain, and only two of the 44 subjects studied had used a combination of drug and non-prescription intervention for pain relief. The majority of participants used non-prescription intervention only and the most commonly used were topical analgesics with massage. The majority (58%) of the subjects perceived the used of non-prescription intervention to be very effective in pain relief. CONCLUSIONS: The prevalence of pain was found to be high among older people in this study. Yet, they were taking a pro-active and responsible role in treating their chronic pain by using non-pharmacological patient-initiated intervention; also older people perceive themselves to have control over their pain status. RELEVANCE TO CLINICAL PRACTICE: This active role of older people in their pain relief is likely to enhance the effect of education seminars and workshops aimed at novel, non-pharmacological pain relief strategies for older people with chronic pain.

Electrochemical alkalization of (Cu-S) n metal-organic framework (MOF) and graphene oxide ((Cu-S) n MOF/GO) composite yields a new CuO/(Cu-S) n MOF/RGO (reduced GO) composite with porous morphology on screen printed carbon electrode (SPCE) which facilitated the electron transfer properties in electrochemical quercetin (QUE) detection. A selective QUE detection ability has been demonstrated by the constructed electrochemical sensor (CuO/(Cu-S) n MOF/RGO/SPCE), which also has a broad dynamic range of 0.5 to 115 µM in pH 3 by differential pulse voltammetry. The detection limit is 0.083 µM (S/N = 3). In this study, it was  observed that the real samples contained 0.34 mg mL -1 and 27.7 µg g -1 QUE in wine and onion, respectively., (© 2024.

Background: The Timed Stair Test (TST) was originally designed to measure advanced functional mobility in patients who have undergone a total hip replacement. Its psychometric properties have not been examined systematically in people with stroke., Aim: The aims of this study were to: 1) determine the intra-rater reliability of TST under loaded and unloaded condition; 2) identify the minimal detectable changes (MDCs) in TST completion times; 3) investigate the concurrent validity between TST completion times and stroke-specific outcome measures; and 4) determine the cut-off TST completion time to differentiate the performance between people with stroke and healthy older adults., Design: Cross-sectional study., Setting: A university-based rehabilitation center., Population: Ninety-four people with stroke and 34 healthy older adults., Methods: TSTs were conducted under loaded and unloaded conditions. Two trials of the TST for each of the two conditions were performed on the same day. The Fugl-Meyer Assessment of Lower Extremity (FMA-LE), lower-limb muscle strength test assessed by a hand held dynamometer, Berg Balance Scale (BBS), Limit of Stability (LOS) Test, Timed Up and Go (TUG) Test, and the Cantonese version of the Community Integration Measure (CIM) were also used to assess the subjects., Results: Excellent intra-rater reliability was demonstrated for TST completion times under loaded (intraclass correlation coefficient [ICC2,1]=0.991) and unloaded (ICC2,1=0.985) conditions. The MDCs in TST completion times were 6.55 seconds and 7.25 seconds under loaded and unloaded conditions, respectively. FMA-LE scores, mean strength of the affected-side dorsiflexors and plantar flexors, BBS scores, and LOS movement velocity and maximum excursion scores demonstrated fair to excellent negative correlations with TST completion times under both loaded (r=-0.314 to -0.786) and unloaded (r=-0.296 to -0.794) conditions. TUG results demonstrated good to excellent positive correlations with TST completion times under both loaded (r=0.875, P<0.001) and unloaded (r=0.872, P<0.001) conditions. The TST completion times of 26.3 seconds and 23.4 seconds under loaded and unloaded conditions, respectively, differentiated between people with stroke and healthy older adults., Conclusions: The TST is a reliable clinical tool for evaluating advanced functional mobility in people with stroke., Clinical Rehabilitation Impact: TST is a fast and simple test that does not require sophisticated equipment, making it suitable for busy hospital and rehabilitation settings.

Background: The Six-Spot Step Test (SSST) was originally developed to assess walking ability while challenging balance during walking in patients with multiple sclerosis. It provides more comprehensive information on ambulatory abilities than several existing measures such as the Timed Up and Go test (TUG test), the Functional Gait Assessment, and the Dynamic Gait Index. To assess the advanced balance control ability of stroke survivors, we modified the SSST to serve this purpose., Aim: The aim of this study was to expand the current understanding of the psychometric properties of the SSST using healthy older adults and stroke survivors., Design: This study adopted an experimental design., Setting: University-affiliated neurorehabilitation laboratory., Population: A total of 50 study participants, including 25 chronic stroke survivors and 25 healthy older adults, were recruited from the community., Methods: The SSST was administered to the stroke survivors twice (day 1 and 2) with a 1-week interval. The Fugl-Meyer assessment for the lower extremities (FMA-LE), the Berg Balance scale (BBS), the limit of stability (LOS) test, the Timed Up and Go test (TUG test), and the Chinese version of the Community Integration Measures (CIM-C) were assessed on day 1 by random order. The healthy control group was assessed with the Six-Spot Step Test only on day 1., Results: The SSST showed excellent inter-rater, intra-rater, and test-retest reliability (intraclass correlation coefficient >0.95, P<0.001). Significant correlations were found between SSST performance and the FMA-LE results (r=0.517, P<0.05), BBS scores (r=-0.531, P<0.05), and TUG test scores (r=0.828, P<0.001). The MDC in the mean SSST time for the affected leg and the unaffected leg in stroke survivors was 6.05s. The cutoff time was 10.11s (sensitivity, 80%; specificity, 92%) when kicking obstacles with the affected leg and 10.18s (sensitivity, 80%; specificity, 92%) when kicking obstacles with the unaffected leg., Conclusions: The SSST was a reliable test and showed a significant correlation with FMA-LE scores, BBS scores, and TUG test times in stroke survivors., Clinical Rehabilitation Impact: The SSST can be used to assess the advanced balance control of stroke survivors.

Purpose This study aims to investigate the effects of dysphonic voice on speech intelligibility in Cantonese-speaking adults. Method Speech recordings from three speakers with dysphonia secondary to phonotrauma and three speakers with healthy voices were presented to 30 healthy listeners (15 men and 15 women; M age = 22.7 years) under six noise conditions (signal-to-noise ratio [SNR] -10, SNR -5, SNR 0, SNR +5, SNR +10) and quiet conditions. The speech recordings were composed of sentences with five different lengths: five syllables, eight syllables, 10 syllables, 12 syllables, and 15 syllables. The effects of speaker's voice quality, background noise condition, and sentence length on speech intelligibility were examined. Speech intelligibility scores were calculated based on the listener's correct judgment of the number of syllables heard as a percentage of the total syllables in each stimulus. Results Dysphonic voices, as compared to healthy voices, were significantly more affected by background noise. Speech presented with dysphonic voices was significantly less intelligible than speech presented with healthy voices under unfavorable SNR conditions (SNR -10, SNR -5, and SNR 0 conditions). However, there was no sufficient evidence to suggest effects of sentence length on intelligibility, regardless of the speaker's voice quality or the level of background noise. Conclusions This study provides empirical data on the impacts of dysphonic voice on speech intelligibility in Cantonese speakers. The findings highlight the importance of educating the public about the impacts of voice quality and background noise on speech intelligibility and the potential of compensatory strategies that specifically address these barriers.

Acute ischaemic stroke due to large vessel occlusion leads to grave neurological morbidity and mortality. Conventional intravenous thrombolysis is ineffective in achieving timely reperfusion in this group of patients. The publication of five positive randomised controlled trials of emergency thrombectomy for acute ischaemic stroke in 2015 provided strong evidence to support endovascular reperfusion therapy and represented a paradigm shift in acute stroke management. In this article, we review the current evidence and international guidelines, and report on the findings of a survey study of the clinical practice and opinions of local neurologists, neurosurgeons, and interventional radiologists in emergency thrombectomy. We also discuss the controversies around thrombectomy treatment, local experience, and suggestions to incorporate thrombectomy in acute stroke treatment.

Introduction: The increasing longevity of people with intellectual disability is testimony to the positive developments occurring in medical intervention. Nonetheless, early-onset age-related issues and concerns cause deterioration of their overall wellbeing. This paper aimed to explore the issues and concerns about individuals with intellectual disability as they age., Methods: Articles that discussed people older than 30 years with an intellectual disability and those that identified ageing health issues and concerns were included. Only studies reported in English from 1996 to 2016 were included. We searched PubMed, Google Scholar, and Science Direct using the terms 'intellectual disability', 'ageing', 'cognitive impairment', 'health', and 'screening'., Results: Apart from the early onset of age-related health problems, dementia is more likely to develop by the age of 40 years in individuals with intellectual disability. Geriatric services to people with intellectual disability, however, are only available for those aged 60 years and older. Cognitive instruments used for the general population are not suitable for people with intellectual disability because of floor effects. In Hong Kong, the Chinese version of the Dementia Screening Questionnaire for Individuals with Intellectual Disabilities is the only validated instrument for people with intellectual disability. The use of appropriate measurement tools to monitor the progression of age-related conditions in individuals with intellectual disability is of great value., Conclusions: Longitudinal assessment of cognition and function in people with intellectual disability is vital to enable early detection of significant deterioration. This allows for therapeutic intervention before substantial damage to the brain occurs such as dementia that hastens cognitive and functional decline.

Objectives: To examine (1) the intra-rater, interrater, and test-retest reliabilities of the timed Up and Go test with a motor task (TUG motor ) in terms of the number of steps taken in the test and completion time in a population with chronic stroke; (2) the relation between stroke-specific impairments and the number of steps taken in the test and the completion time; (3) the minimum detectable change in TUG motor times; and (4) the cutoff time that best discriminates the performance of people with stroke from that of older adults without stroke., Design: Cross-sectional study., Setting: University-based rehabilitation center., Participants: A sample (N=65) of chronic stroke survivors (n=33) and healthy older adults (n=32)., Interventions: Not applicable., Main Outcome Measures: TUG motor times and number of steps taken; Fugl-Meyer Assessment for the Lower Extremities score; handheld dynamometer measurements of hip abductor, knee flexor and extensor, and ankle dorsiflexor and plantar flexor muscle strength; 5-times sit-to-stand test time, Berg Balance Scale score; conventional timed Up and Go test time, and Activities-specific Balance Confidence scale and Community Integration Measure questionnaire scores., Results: The TUG motor completion times and number of steps demonstrated excellent intra-rater, interrater, and test-retest reliabilities. The TUG motor times correlated significantly with the Fugl-Meyer Assessment for the Lower Extremities and Berg Balance Scale scores, with hip abductor, knee flexor, ankle dorsiflexor and plantar flexor strength on the paretic side, with 5-times sit-to-stand test times, and with times on the conventional timed Up and Go test. The minimum detectable change in TUG motor time was 3.53 seconds in stroke survivors. A TUG motor cutoff time of 13.49 seconds was found to best discriminate the performance of stroke survivors from that of older adults without stroke., Conclusions: The TUG motor is a reliable, valid, and easy-to-administer clinical tool for assessing advanced functional mobility after a stroke., (Copyright © 2017 American Congress of Rehabilitation Medicine.

Objective: To evaluate the feasibility and preliminary effects of an individualized exercise programme with and without behavioural change enhancement strategies for frail older people with fatigue., Design: A three-arm, single-blinded, quasi-experimental pilot study., Setting: Community health centres., Participants: A total of 79 frail older people with fatigue, mean age 79.32 years (±7.72)., Interventions: The combined group received a 16-week combined intervention consisting of exercise training and a behavioural change enhancement programme. The exercise group received exercise training and health talks, whereas the control group received only health talks., Main Outcome Measure(s): Feasibility was assessed through the participants' recruitment, retention, attendance and adherence, feedback, and reports of adverse events. The preliminary effects were assessed by the participants' level of fatigue, physical endurance, self-efficacy, and self-perceived compliance with exercise., Results: Feasibility was achievable with high recruitment (87.2%) and low overall attrition (7.1%) rates. A similar reduction in fatigue was identified in all groups, but a trend of greater improvement in physical endurance was observed in the combined group than in the other two groups. The combined group also had a significantly better attendance rate [F(2,76) = 5.64, p < 0.01)] and higher self-perceived exercise compliance than the exercise group., Conclusion: The combined intervention has the potential to enhance the participants' adherence to exercise regimens by improving their attendance in training sessions and their self-perceived exercise compliance. They are important to maintaining an appropriate level of engagement in daily exercises, especially at the beginning stages of behavioural change, when the participants are establishing the habit of exercising daily.

Objectives: To investigate (i) the intra-rater, inter-rater and test-retest reliability of sideways walk test times and counts in individuals with stroke; (ii) their correlations with stroke-specific measures of impairment; (iii) the cut-off sideways walk test times and counts between stroke survivors and healthy controls; and (iv) the minimum detectable changes in the sideways walk test times and counts., Design: Cross-sectional study., Setting: University-based rehabilitation centre., Subjects: Twenty-nine older adults with stroke and 32 healthy controls., Methods: The sideways walk test was conducted together with Fugl-Meyer motor assessments of the lower extremities, lower limb muscle strength tests, the Five-Times-Sit-To-Stand test, Berg Balance Scale, Timed Up-and-Go test, and Activity-based Confidence and Community Integration Measure questionnaires., Results: The sideways walk test times and counts demonstrated good to excellent intra-rater, inter-rater, and test-retest reliabilities. The sideways walk test times and counts were significantly correlated with motor control and ankle dorsiflexor and plantarflexor strength of the affected leg, balance performance and functional mobility. The cut-off sideways walk test time and count that best discriminated between individuals with stroke and controls were 10.74 s and 8.83 steps, respectively. The minimal detectable change in the sideways walk test time in that situation was 1.85 s, and the count minimum detectable change was 1.12 steps., Conclusion: The sideways walk test is a reliable and easy-to-administer clinical test for assessing sideways walking ability of individuals with chronic stroke.

OBJECTIVES : To examine the feasibility of a peer-led pain management program among nursing home residents. DESIGN : A quasi-experimental design. SETTING : Two nursing homes. SUBJECTS : Fifty nursing home residents. METHODS : The experimental group (n = 32) was given a 12-week group-based peer-led pain management program. There were two 1-hour sessions per week. Education in pain and demonstrations of nonpharmacological pain management strategies were provided. The research team and 12 trained peers led the sessions. The control group (n = 18) received one 1-hour session of pain management program each week over 12 weeks from the research team only. Outcome measures for the participants were collected at baseline (P1) and at week 12 (P2). Data from peer volunteers were collected prior to training (V1) and at week 12 (V2). T-tests were used to compare the differences in outcome measures collected at two time points. RESULTS : There was a significant reduction in pain intensity from 5.8 ± 2.6 (P1) to 3.4 ± 2.5 (P2) for the experimental group (p = 0.003) and from 6.3 ± 3.0 (P1) to 3.1 ± 2.4 (P2) for the control group (p = 0.001). Activities of daily living significantly improved for both the experimental group (p = 0.008) and the control group (p = 0.014). There was an enhancement in happiness level for the experimental group (p < 0.001), while the loneliness level dropped significantly for the experimental group (p < 0.001) and the control group (p = 0.031). The peer volunteers showed a significant increase in self-rated pain management knowledge (2.9 ± 2.6 to 8.1 ± 1.2, p < 0.001) and self-efficacy in volunteering (5.8 ± 2.9 to 8.3 ± 1.5, p = 0.032). CONCLUSION : The peer-led pain management program was feasible and has potential in relieving chronic pain and enhancing the physical and psychological health of nursing home residents., (© 2016 American Academy of Pain Medicine.

WHAT IS KNOWN ON THE SUBJECT?: Frailty and multimorbidity are common in later life. A higher level of frailty is associated with a higher risk of adverse physical and psychological health situations. Older adults with pain have been reported to be lonelier and more depressed, as well as less happy and less satisfied with their life as compared to those without pain. In view of the high prevalence of pain among older adults and the reversibility of frailty, it is important to explore the relationship between pain, frailty and psychological parameters in order to devise patient-centred interventions. WHAT THIS PAPER ADDS TO EXISTING KNOWLEDGE?: Frailty index is positively correlated with the presence of pain, and associated with gender, functional mobility and loneliness. Among these significant variables, loneliness was the factor that contributed the most to the frailty index. WHAT ARE THE IMPLICATIONS FOR PRACTICE?: It is essential to put the focus of healthcare on both the physical and psychological aspects of well-being. All nurses are advised to improve the management of pain in older people in order to lower the levels of pain, frailty and psychological distress among this population. Nursing care should address the loneliness level especially the problem of social loneliness among older adults particularly those living in nursing homes., Abstract: Introduction In view of the high prevalence of pain among older adults and the reversibility of frailty, it is important to explore the relationship between pain, frailty and psychological parameters in order to devise patient-centred interventions. Aim To examine the levels of frailty, pain and psychological parameters among older adults living in Hong Kong nursing homes, and the cross-sectional relationships among these items. Methods A cross-sectional study was conducted among 178 residents from six nursing homes. Frailty, pain, mobility, happiness, loneliness and life satisfaction of participants were assessed using validated questionnaires. Results A multiple linear regression (R(2)  = 0.338, P < 0.05) showed that the frailty index was associated with loneliness, functional mobility and gender. Among these significant variables, loneliness was the factor that contributed the most to the frailty index. Discussion It is essential to put the focus of healthcare on both the physical and psychological aspects of well-being. Findings suggest that apart from improving mobility and reducing pain, loneliness could be a target of psychosocial interventions to reduce frailty and improve quality of life. Implications for practice It is advised that nursing care should address loneliness, especially the problem of social loneliness among older adults particularly those living in nursing homes., (© 2016 John Wiley & Sons Ltd.)

[Purpose] To investigate the inter-rater and test-retest reliability of the sitting-rising test (SRT), the correlations of sitting-rising test scores with measures of strength, balance, community integration and quality of life, as well as the cut-off score which best discriminates people with chronic stroke from healthy older adults were investigated. [Subjects and Methods] Subjects with chronic stroke (n=30) and healthy older adults (n=30) were recruited. The study had a cross-sectional design, and was carried out in a university rehabilitation laboratory. Sitting-rising test performance was scored on two occasions. Other measurements included ankle dorsiflexor and plantarflexor strength, the Fugl-Meyer assessment, the Berg Balance Scale, the timed up and go test, the five times sit-to-stand test, the limits of stability test, and measures of quality of health and community integration. [Results] Sitting-rising test scores demonstrated good to excellent inter-rater and test-retest reliabilities (ICC=0.679 to 0.967). Sitting-rising test scores correlated significantly with ankle strength, but not with other test results. The sitting-rising test showed good sensitivity and specificity. A cut-off score of 7.8 best distinguished healthy older adults from stroke subjects. [Conclusions] The sitting-rising test is a reliable and sensitive test for assessing the quality of sitting and rising movements. Further studies with a larger sample are required to investigate the test's validity.

Objectives: This study aimed to measure cardiac output, systemic vascular resistance, cardiac index, and systemic vascular resistance index in emergency department patients with poorly controlled hypertension; and to determine the frequency in which antihypertensive drugs prescribed do not address the predominant haemodynamic abnormality., Methods: This cross-sectional observational study was conducted in an emergency department of a 1400-bed tertiary hospital in Hong Kong. Patients aged 18 years or above, with systolic blood pressure of ≥160 mm Hg or diastolic blood pressure of ≥100 mm Hg based on two or more measurements and on two separate occasions within 2 to 14 days, were included. Haemodynamic measurements were obtained using a non-invasive Doppler ultrasound monitor. Doctors were blinded to the haemodynamic data. Any antihypertensive medication adjustment was evaluated for correlation with haemodynamic changes., Results: Overall, 164 patients were included. Their mean age was 69.0 years and 97 (59.1%) were females. Systemic vascular resistance and cardiac output were elevated in 65.8% (95% confidence interval, 57.9-72.9%) and 15.8% (10.8-22.5%) of patients, respectively. Systemic vascular resistance index and cardiac index were elevated in 43.9% (95% confidence interval, 36.2-51.8%) and 19.5% (13.9-26.5%) of patients, respectively. Of 71 patients in whom antihypertensive medications were adjusted, 25 (35.2%; 95% confidence interval, 24.5-47.5%) were prescribed agents that did not correlate with the primary haemodynamic abnormality., Conclusions: The profile of haemodynamic changes in emergency department patients with poorly controlled hypertension is characterised. The antihypertensive drugs prescribed did not correspond to the patient's primary haemodynamic derangement in 35% of cases.

Aim: To provide an overview of the administration of opioid analgesics by nurses when prescription is on an "as-needed" basis for postoperative pain, and to identify the important factors that determine the decisions of nurses, by using the framework of predisposing, reinforcing, and enabling causes in educational diagnosis and evaluation., Methods: Multiple databases were searched for the period from 2000-2012. Out of a total of 1755 citations and 148 abstracts retrieved, 39 studies met the criteria for inclusion. Studies were considered eligible for review if they focused on situations or factors influencing a nurse's performance in pain assessment and the administration of opioid analgesics in postoperative pain management., Results: The topics of the descriptive and qualitative studies presented four themes: (i) nurses' knowledge and attitudes about pain management; (ii) the situation of nurses' work practices in administrating range orders for opioid analgesics; (iii) factors that influenced nurses' work practices; and (iv) perceived barriers to effective pain management from the nurse's perspective. The experimental studies investigated the effects of different approaches in nurses' pain management practices in postoperative settings and their outcomes for patients., Conclusion: A knowledge deficit was observed to be the reason in most cases for a nurse's failure to administrate adequate analgesics for postoperative pain relief. Pain-related education for nurses is the cornerstone to improve pain management. The integration of enabling and reinforcing factors will help nurses to develop the ability to make the decision to engage in a comprehensive intervention to improve pain management and patient outcomes., (© 2015 The Authors.

[Purpose] This study investigated the intra-rater, inter-rater and test-retest reliability of the sideways step test (SST), its correlation with other indicators of stroke-specific impairment, and the cut-off count best discriminating subjects with stroke from their healthy counterparts. [Subjects and Methods] Forty-three subjects with chronic stroke and 41 healthy subjects older than 50 years participated in this study. The SST was administered along with the Fugl-Meyer motor assessment for the lower extremities (FMA-LE), the five-times sit to stand (5TSTS) test, the Berg Balance Scale (BBS), the movement velocity (MVL) by the limits of stability (LOS) test, the ten-metre walk (10mW) test, the timed "Up and Go" (TUG) test and the Activities-specific Balance Confidence (ABC) scale. [Results] The SST showed good to excellent intra-rater, inter-rater and test-retest reliability. The SST counts correlated with 5TSTS times, 10mW times, TUG times, and the FMA-LE and BBS scores. SST counts of 11 for the paretic leg and 14 for the non-paretic leg were found to distinguish the healthy adults from subjects with stroke. [Conclusion] The sideways step test is a reliable clinical test, which correlates with the functional strength, gait speed, and functional balance of people with chronic stroke.

Objective: To investigate: (i) intra-rater, inter-rater and test-retest reliability of the Timed Floor Transfer Test (FTT); (ii) validity of FTT times with stroke-specific impairments and functional mobility; and (iii) cut-off time that best discriminates people with stroke from healthy older adults., Design: Cross-sectional study., Setting: University-based rehabilitation laboratory., Subjects: Forty-seven people with stroke and 35 healthy older adults., Methods: FTT completion times were measured along with a Fugl-Meyer assessment of the lower extremities (FMA-LE); Five Times Sit-To-Stand Test (FTSTST) completion times, Berg Balance Scale (BBS) scores; Timed "Up & Go" (TUG) test; and assessment using the Activities-specific Balance Confidence Scale (ABC)., Results: FTT completion times showed good to excellent intra-rater, inter-rater and test-retest reliability. The minimal detectable change of FTT completion times was 7.7 s. A cut-off time of 8.8 s was found to discriminate well between people with stroke and healthy older adults. The FTT times showed significant negative correlation with FMA-LE scores and BBS scores, and significant positive correlation with FTSTS completion times and TUG times., Conclusion: The FTT is a reliable clinical test for assessing the floor-transfer ability of people with chronic stroke.

Objectives: To investigate (1) the intrarater, interrater, and test-retest reliability of the times and scores generated in the parallel walk test (PWT); (2) their correlations with impairments and activity limitations of individuals with stroke; and (3) the cutoff times that best discriminate individuals with stroke from healthy elderly subjects., Design: Cross sectional study., Setting: University-based rehabilitation center., Participants: Participants (N=72) comprised individuals with stroke (n=37) and healthy individuals (n=35)., Interventions: Not applicable., Main Outcome Measures: The PWT was administered along with the Fugl-Meyer Motor Assessment of the Lower Extremities (FMA-LE), handheld dynamometer measurements of ankle dorsiflexor and plantarflexor muscle strength, the 5-Times-Sit-to-Stand Test, the Berg Balance Scale (BBS), a limits of stability (LOS) test, the 10-m walk test (10-MWT), and the timed Up and Go (TUG) test., Results: PWT times and scores showed good to excellent intrarater, interrater, and test-retest reliability in individuals with stroke. PWT times using paths of 3 different widths significantly correlated with FMA-LE scores, 5-Times-Sit-to-Stand Test times, BBS scores, some LOS test results, 10-MWT gait speed, and TUG test times. PWT times of 6.30 to 7.48 seconds, depending on the path width, were shown reliably to discriminate individuals with stroke from healthy individuals., Conclusion: The PWT is a reliable, easy-to-administer clinical tool for assessing dynamic walking balance in individuals with chronic stroke., (Copyright © 2015 American Congress of Rehabilitation Medicine.

Objective: This study aimed to establish learning profiles for noninvasive transcutaneous Doppler ultrasound., Materials and Methods: Four trainees attended a 2-h lecture, followed by a 15-min demonstration on a volunteer and a 30-min hands-on workshop in a small group setting. Then, they underwent hands-on practice on 50 participants without supervision. The skill acquisitions in terms of signal magnitude, signal quality, and measurement time of the trainees were evaluated through 50 assessments, and were compared with that of a trainer with extensive experience on the use of an ultrasonic cardiac output monitor acting as a 'gold standard'. The learning profile for each individual trainee was analyzed using the cumulative sum graphical method., Results: Four trainees performed ultrasonic cardiac output monitor on 50 participants. All trainees attained proficiency after 18-36 assessments to achieve aortic signal magnitude and quality comparable with the trainer. It requires a minimum of nine assessments to obtain three aortic scans within 5 min with 95% success rates. Only half of the trainees achieved competence in pulmonary scans and the minimum number of assessments required was 36. A minimum of 22 assessments were required for three pulmonary scans within 10 min with 95% success rates., Conclusion: A substantial period of learning needs to be undertaken to achieve proficiency on the use of noninvasive transcutaneous Doppler ultrasound. Cumulative sum analysis is a useful tool for ongoing quality assessment during medical education and training in practical procedures on an individual basis.

Pain is common in the aging population, particularly among older residents of nursing homes. It has been found that 50% of older people living in the community have been experiencing chronic pain, and the number increased to 80% for older residents of nursing homes. Exercise is an effective non-pharmacological intervention that can reduce pain and improve physical and psychological functions. A quasi-experimental study with a pretest-posttest control group designed was conducted to evaluate the effects of a physical exercise program (PEP) on older residents of nursing homes who have chronic pain. Three-hundred-ninety-six older residents with chronic pain were recruited from 10 nursing homes run by non-governmental organizations in Hong Kong. The average age of the older residents was 85.44 ± 6.29. Five nursing homes were randomized to the experimental group with PEP (n = 225, age = 85.45 ± 6.25); the other five nursing homes were randomized to the control group without the PEP (n = 171, age = 85.44 ± 6.35). PEP was an eight-week training program given by a physiotherapist and nurses once a week. It consisted of warm-up exercises, muscle strengthening, stretching, balancing, and self-administered massage to acupressure points. At the end of each PEP session, pamphlets with pictures illustrating the "exercise of the day" were given to the older residents of nursing homes as a tool to enhance their self-management skills. The control group received no training during the eight weeks. Upon completion of the PEP, the experimental group experienced a significantly greater reduction in pain intensity from 4.19 ± 2.25 (on an 11 point scale) to 2.67 ± 2.08, as compared to the control group (p < .05). In addition, the psychological well-being (happiness, loneliness, life satisfaction, and depression) of the experimental group was significantly improved (p < .05)., (Copyright © 2014 American Society for Pain Management Nursing.

Background: Chronic pain is common among the older population. A literature review on pain management program showed that exercise, yoga, massage therapy, Tai Chi, and music therapy could significantly reduce pain. In spite of the proven benefits of pain management programs, these intervention programs were effective only in the short term, and older adults would resume their old habits. It has been suggested that interventions comprising some type of social support have great potential to increase the participation of older adults. Therefore, we propose the inclusion of peer volunteers in an integrated pain management program to relieve pain among frail older adults. This study aims to explore the effectiveness of an integrated pain management program supplemented with peer volunteers in improving pain intensity, functional mobility, physical activity, loneliness levels, happiness levels, and the use of non-pharmacological pain-relieving methods among frail older adults with chronic pain., Methods/design: We intend to recruit 30 nursing home residents and 30 peer volunteers from the Institute of Active Ageing in Hong Kong in a group trial for an 8-week group-based integrated pain management program. There will be 16 sessions, with two 1-hour sessions each week.The primary outcome will be pain levels, while secondary outcomes will be assessed according to functional mobility, physical activity, loneliness levels, happiness levels, the use of non-pharmacological pain-relieving methods, and through a questionnaire for volunteers., Discussion: In view of the high prevalence of chronic pain among older adults and its adverse impacts, it is important to provide older adults with tools to control their pain. We propose the use of peer volunteers to enhance the effects of an integrated pain management program. It is expected that pain can be reduced and improvements can be achieved among older adults in the areas of physical activity, functional mobility, loneliness levels, happiness levels, and the use of non-pharmacological pain relieving methods. Using these results, we will assess the need to conduct a larger study with a randomized controlled design., Trial Registration: This trial was registered on 24 February 2014 at the Australian New Zealand Clinical Trials Registry (ANZCTR) with the trial number: ACTRN12614000195651.

The aim of the study was to examine the effectiveness of a pain management program (PMP) in enhancing the knowledge and attitudes of health care workers in pain management. Many nursing home residents suffer from pain, and treatment of pain is often inadequate. Failure of health care workers to assess pain and their insufficient knowledge of pain management are barriers to adequate treatment. It was a quasiexperimental pretest and posttest study. Four nursing homes were approached, and 88 staff joined the 8-week PMP. Demographics and the knowledge and attitudes regarding pain were collected with the use of the Nurse's Knowledge and Attitudes Survey Regarding Pain-Chinese version (NKASRP-C) before and after the PMP. A deficit in knowledge and attitudes related to pain management was prominent before the PMP, and there was a significant increase in pain knowledge and attitudes from 7.9 ± SD 3.52 to 19.2 ± SD4.4 (p < .05) after the 8-week PMP. A PMP can improve the knowledge and attitudes of nursing staff and enable them to provide adequate and appropriate care to older persons in pain. PMPs for nurses and all health care professionals are important in enhancing care for older adults and to inform policy on the provision of pain management., (Copyright © 2014 American Society for Pain Management Nursing.

Objective: Pipeline embolization device (PED) implantation is a novel endovascular treatment option for the treatment of intracranial aneurysms. It is emerging as a useful alternative to coiling and to open surgery, and its use is increasing worldwide. We performed a literature review to examine its efficacy, technical challenges, and safety., Methods: PubMed database was used to identify all articles relating to PED., Results: The review outlines the indications for PED, its technical aspects, complications, and clinical outcomes., Conclusions: PED offers an alternative to endovascular coiling for aneurysms with complex morphology. The indication for its use has evolved from the limited scope of treatment of giant aneurysms with wide necks to the inclusion of smaller aneurysms. The procedural safety profile of PED is comparable with or possibly superior to balloon-remodeling or stent-assisted coil embolization in specific circumstances. However, questions remain regarding the incidence of post-procedural subarachnoid hemorrhage. Ongoing monitoring and meticulous documentation of PED postimplantation safety is strongly recommended., (Copyright © 2013. Published by Elsevier Inc.)

Aims and Objectives: To examine the effectiveness of an integrated motivational interviewing and physical exercise programme on pain, physical and psychological function, quality of life, self-efficacy, and compliance with exercise for community-dwelling older persons with chronic pain., Background: Chronic pain is common among older persons. Indeed, motivation for managing pain is poor, and may cause negative consequences. Motivational interviewing maybe effective in treating chronic pain., Design: Single-blinded randomised control study., Methods: Older persons with chronic pain (n = 56) were recruited from two elderly community centres. They were blinded from the group allocation. The programme was conducted by an motivational interviewing-trained physiotherapist and registered nurses. Participants in the experimental group received an 8-week integrated motivational interviewing and physical exercise programme, while the control group received regular activities in the centre. Motivational interviewing used open-ended questions to encourage participants to express and recognise their pain and behaviours and professional feedback was given accordingly. Pain intensity, pain self-efficacy, anxiety, happiness, depression, mobility and quality of life were measured before and after the motivational interviewing and physical exercise programme. Attendance and compliance rate of the programme was calculated in the experimental group., Results: Significant improvements in pain intensity, pain self-efficacy, anxiety, happiness and mobility after the motivational interviewing and physical exercise programme (all p < 0.05) for experimental group, while no significant improvement in control group except on the happiness scale. Regarding group differences in the outcome measures, the change scores on pain intensity, state anxiety and depression were significantly better in the experimental group., Conclusion: Motivational interviewing and physical exercise programme is effective in improving pain, physical mobility, psychological well-being and self-efficacy for community-dwelling older persons with chronic pain., Relevance to Clinical Practice: Motivational interviewing is a feasible counselling technique whose content can be modified based on target group to change maladaptive behaviours, elicit ambivalences and enhance self-efficacy for making changes. Thus, promoting motivational interviewing and physical exercise programme to older persons with pain is effective and important., (© 2013 Blackwell Publishing Ltd.)

Because the prevalence of chronic pain among the elderly in nursing homes is high and decreases their quality of life, effective nonpharmacologic pain management should be promoted. The purpose of this quasiexperimental pretest and posttest control design was to enhance pain management in nursing homes via an integrated pain management program (IPMP) for staff and residents. Nursing staff and residents from the experimental nursing home were invited to join the 8-week IPMP, whereas staff and residents from the control nursing home did not receive the IPMP. Baseline data were collected from nursing staff and residents in both groups before and after the IPMP. The IPMP consisted of eight lectures on pain assessment, drug knowledge,and nondrug strategies for the nursing staff, and 8 weeks of activities, including gardening therapy and physiotherapy exercise, for the residents. There were 48 and 42 older people in the experimental and control groups, respectively. No significant differences were found in their educational level, sleep quality, bowel habits, past and present health conditions, pain conditions and psychologic well-being parameters (p > .05) at baseline. After the IPMP, the experimental nursing staff showed a significant improvement in their knowledge of and attitudes to pain management (p < .05), and the experimental residents reported significantly lower pain scores and used more nondrug strategies for pain relief compared with the control group (p < .05). Moreover, the psychologic well-being parameters, including happiness, loneliness, life satisfaction, and geriatric depression, had significantly improved among the experimental residents (p < .05). The IPMP was effective in enhancing the knowledge and attitudes of nursing staff, as well as reducing pain conditions and enhancing psychologic well-being for older persons in nursing homes., (Copyright © 2013 American Society for Pain Management Nursing.

We have previously shown that isoproterenol-induced cardiac hypertrophy causes significant changes to cytochromes P450 (CYPs) and soluble epoxide hydrolase (sEH) gene expression. Therefore, in this study, we examined the effect of isoproterenol in H9c2 cells, and the protective effects of 14,15-EET against isoproterenol-induced cellular hypertrophy. Isoproterenol was incubated with H9c2 cells for 24 and 48 h. To determine the protective effects of 14,15-EET, H9c2 cells were incubated with isoproterenol in the absence and presence of 14,15-EET. Thereafter, the expression of hypertrophic markers and different CYP genes were determined by real time-PCR. Our results demonstrated that isoproterenol significantly increased the expression of hypertrophic marker, atrial natriuretic peptide (ANP) and brain natriuretic peptide (BNP), parallel to a significant increase in cell surface area. Also, isoproterenol increased the mRNA expression of CYP1A1, CYP1B1, CYP2J3, CYP4F4 and CYP4F5, as well as the gene encoding sEH, EPHX2. On other hand, 14,15-EET significantly attenuated the isoproterenol-mediated induction of ANP, BNP, CYP1A1, CYP2J3, CYP4F4, CYP4F5 and EPHX2. Moreover 14,15-EET prevented the isoproterenol-mediated increase in cell surface area. Interestingly, 20-hydroxyeicosatetraenoic acid (20-HETE) treatment caused similar effects to that of isoproterenol treatment and induced cellular hypertrophy in H9c2 cells. In conclusion, isoproterenol induces cellular hypertrophy and modulates the expression of CYPs and EPHX2 in H9c2 cells. Furthermore, 14,15-EET exerts a protective effect against isoproterenol-induced cellular hypertrophy whereas, 20-HETE induced cellular hypertrophy in H9c2 cells., (Copyright © 2013 Elsevier Inc.

A plethora of studies have demonstrated the expression of cytochrome P450 (CYP) and soluble epoxide hydrolase (sEH) enzymes in the heart and other cardiovascular tissues. In addition, the expression of these enzymes is altered during several cardiovascular diseases (CVDs), including cardiac hypertrophy (CH). The alteration in CYP and sEH expression results in derailed CYP-mediated arachidonic acid (AA) metabolism. In animal models of CH, it has been reported that there is an increase in 20-hydroxyeicosatetraenoic acid (20-HETE) and a decrease in epoxyeicosatrienoic acids (EETs). Further, inhibiting 20-HETE production by CYP ω-hydroxylase inhibitors and increasing EET stability by sEH inhibitors have been proven to protect against CH as well as other CVDs. Therefore, CYP-mediated AA metabolites 20-HETE and EETs are potential key players in the pathogenesis of CH. Some studies have investigated the molecular mechanisms by which these metabolites mediate their effects on cardiomyocytes and vasculature leading to pathological CH. Activation of several intracellular signaling cascades, such as nuclear factor of activated T cells, nuclear factor kappa B, mitogen-activated protein kinases, Rho-kinases, Gp130/signal transducer and activator of transcription, extracellular matrix degradation, apoptotic cascades, inflammatory cytokines, and oxidative stress, has been linked to the pathogenesis of CH. In this review, we discuss how 20-HETE and EETs can affect these signaling pathways to result in, or protect from, CH, respectively. However, further understanding of these metabolites and their effects on intracellular cascades will be required to assess their potential translation to therapeutic approaches for the prevention and/or treatment of CH and heart failure.

Background and Purpose: We have previously shown that isoprenaline-induced cardiac hypertrophy causes significant changes in the expression of cytochromes P450 (CYP) and soluble epoxide hydrolase (sEH) genes. Therefore, it is important to examine whether the inhibition of sEH by 1-(1-methanesulfonyl-piperidin-4-yl)-3-(4-trifluoromethoxy-phenyl)-urea (TUPS) will protect against isoprenaline-induced cardiac hypertrophy., Experimental Approach: Male Sprague-Dawley rats were treated with TUPS (0.65 mg kg(-1) day(-1), p.o.), isoprenaline (5 mg kg(-1) day(-1), i.p.) or the combination of both. In vitro H9c2 cells were treated with isoprenaline (100 μM) in the presence and absence of either TUPS (1 μM) or 11,12 EET (1 μM). The expression of hypertrophic, fibrotic markers and different CYP genes were determined by real-time PCR., Key Results: Isoprenaline significantly induced the hypertrophic, fibrotic markers as well as the heart to body weight ratio, which was significantly reversed by TUPS. Isoprenaline also caused an induction of CYP1A1, CYP1B1, CYP2B1, CYP2B2, CYP4A3 and CYP4F4 gene expression and TUPS significantly inhibited this isoprenaline-mediated effect. Moreover, isoprenaline significantly reduced 5,6-, 8,9-, 11,12- and 14,15-EET and increased their corresponding 8,9-, 11,12- and 14,15-dihydroxyeicosatrienoic acid (DHET) and the 20-HETE metabolites. TUPS abolished these isoprenaline-mediated changes in arachidonic acid (AA) metabolites. In H9c2 cells, isoprenaline caused a significant induction of ANP, BNP and EPHX2 mRNA levels. Both TUPS and 11,12-EET significantly decreased this isoprenaline-mediated induction of ANP, BNP and EPHX2., Conclusions and Implications: TUPS partially protects against isoprenaline-induced cardiac hypertrophy, which confirms the role of sEH and CYP enzymes in the development of cardiac hypertrophy., (© 2012 The Authors.

Frontotemporal dementia (FTD) has rarely been reported in Chinese populations. There are many potential reasons for this, including possible hesitancy on the part of patients or families to bring FTD-related symptoms to medical attention. Here, we present data on eight Chinese individuals, all of whom met criteria for the behavioral variant of FTD or the semantic variant of primary progressive aphasia. These patients presented for neurological evaluation at a relatively advanced stage. The mean MMSE score at initial presentation was 15. Behavioral symptoms were common and usually elicited during the medical history only after direct questioning. Delay in presentation was attributed to a variety of issues, including family disagreements about whether the symptoms represented a disease and lack of medical insurance. These cases illustrate that the symptoms of FTD in Chinese-Americans are similar to those in Caucasians but various factors, some potentially culturally relevant, may influence the likelihood and timing of clinical presentation for FTD, as well as other dementias. Additional study of FTD in diverse ethnic groups needs to address barriers to clinical presentation, including factors that may be culturally specific.

Background: Pain is 1 of the most common symptoms that a cancer patient would experience. A significant barrier to positive pain management is patients' misconceptions regarding analgesics and inadequate use of nonpharmacological strategies as pain relief., Objective: The purpose of this study was to investigate the effectiveness of a pain management program (PMP) on pain intensity, use of PRN drugs and nonpharmacological strategies as pain relief, and barriers to managing pain in cancer patients., Methods: The study was conducted in the palliative care and hospice ward of a public hospital in Hong Kong. Patients were randomized to either an experimental group (receiving the PMP) or a control group (routine care). There were 38 hospitalized patients, with 20 (13 males and 7 females) in the experimental group and 18 (11 males and 7 females) in the control group; mean age was 61.95 years (experimental group) to 63.94 years (control group)., Results: Upon the completion of PMP, pain scores were significantly reduced in both groups, yet patients in the experimental group showed a significant increase in the use of PRN analgesics and nonpharmacological strategies to relieve pain (P < .05) and significantly reduce barriers to managing their cancer pain (P < .05) compared with the control group., Conclusion: Cancer patients should be empowered with pain management education to gain knowledge and correct misconceptions in managing their cancer pain., Implications for Practice: Integration of the PMP into routine clinical work may help to improve the standard of care for cancer patients. It is recommended to provide pain management education to all cancer patients.

Background: Inadequate infection control knowledge about enteral feeding (EF) practices among nursing home staff may lead to contamination of EF systems., Aim: To investigate the effectiveness of an infection control programme (ICP) on knowledge and practice of EF of nursing home staff, and to explore the correlation between the ICP and bacterial contamination of the hands of staff and feeding equipment., Methods: Using a quasi-experimental pre-post-test control design, each intervention and control group consisted of 15 residents and 10 staff. EF knowledge and practice were assessed by questionnaire and observation. The intervention group received an ICP. Samples were collected from the hands of staff, enteral feed, flow regulators, feeding tube hubs, and the nasopharynx and gastric fluid of residents, and analysed for total bacterial counts and presence of meticillin-resistant Staphylococcus aureus (MRSA) before and after the ICP., Findings: The intervention group showed a significant improvement in knowledge and practice after the ICP (P < 0.05). Pretest samples from the hands of staff, tube hubs, and the nasopharynx and gastric fluid of residents were contaminated with >10(4) colony-forming units/mL. Contamination was significantly lower in the post-test samples of the intervention group (P < 0.05), and remained unchanged in the control group. The mean (± standard deviation) number of MRSA-positive samples decreased from 2.1 ± 1.6 to 0.4 ± 0.7 (P < 0.05) in the intervention group. MRSA hand contamination was highly correlated with contamination of regulators, gastric fluid, tube hubs and enteral feed (P < 0.05), illustrating the close relationship between contaminated feed and poor hand hygiene., Conclusion: An effective ICP can significantly reduce the contamination of enteral feed. The provision of ICPs is strongly recommended in nursing homes., (Copyright © 2012 The Healthcare Infection Society. Published by Elsevier Ltd. All rights reserved.)

Aims: The purpose of this study was (1) to explore postoperative pain experience among Chinese thoracotomy patients during hospitalisation; (2) to identify patient-related barriers to pain management; and (3) to explore how these barriers were related to patients' pain experience., Background: Major thoracotomy causes severe pain and extreme stress for patients. Unrelieved postoperative pain leads to high risks of postoperative complications and chronic post-thoracotomy pain syndrome, compromising the quality of life for those patients., Design: Cross-sectional design., Methods: A tertiary general hospital in mainland China was selected for this study. A total of 94 patients undergoing scheduled major thoracotomy operations participated in the study. All patients completed Brief Pain Inventory-Chinese version, the Barrier Questionnaire-Taiwan Form Surgical version and a demographic questionnaire., Results: Patients suffered moderate to severe pain and experienced extremely high interferences with daily activities after major thoracotomy operation. Patients reported the four highest barrier scores in the subscale of Barrier Questionnaire-Taiwan Form Surgical version were fear of tolerance, inhibition of wound healing, time intervals and distracting the physician from treating the disease. Patient's demographic data had no significant impact on their concerns about communicating pain and using of analgesics with exception of the subscale 'fatalism' of the Barrier Questionnaire-Taiwan Form Surgical version in patients with higher education levels or patients with 'non-farmer' occupation. However, there were no significant correlations indicated either between Barrier Questionnaire-Taiwan Form Surgical version score and pain severity or pain interference., Conclusions: Patients were underexposure of pain treatment after thoracotomy operation in the study, while patients' concerns about reporting pain and using analgesics had minimal impacts on their pain experience., Relevance to Clinical Practice: Education approach for patients is inadequate to improve the status of unrelieved postoperative pain. Appropriate pain management regime together with attentive nursing care should be provided to achieve better pain relief for Chinese patients., (© 2011 Blackwell Publishing Ltd.)

This study examined the effects of an 8-week integrated pain management program (IPMP) on enhancing the knowledge and attitude toward pain management among staff; and improving the pain, quality of life, physical and psychosocial functions, and use of non-drug therapies for the elderly in nursing homes. Nursing home staff (N=147) and residents (N=535) were recruited from ten nursing homes. Nursing homes were randomly assigned into an experimental group (N=296) with IPMP or control group (N=239) without IPMP. The IPMP consisted of pain education for staff and physical exercise and multisensory stimulation art and craft therapy for residents. Data were collected before and after the IPMP. The staff demonstrated a significant improvement in knowledge and attitude to pain management, with the survey score increasing from 8.46±3.74 to 19.43±4.07 (p<0.001). Among the residents, 74% had experienced pain within the previous 6 months, with pain intensity of 4.10±2.20. Those in the experimental group showed a significantly better reduction in pain scores than the control group, from 4.19±2.25 to 2.67±2.08 (p<0.001). Group differences were also found in psychological well-being, including happiness, loneliness, life satisfaction and depression (p<0.05), and the use of non-drug methods (p<0.05). These results suggested that IPMP is beneficial for staff, and is effective in reducing geriatric pain and negative impacts. Management support and staff involvement in the program are important for its long-term continuation., (Copyright © 2011 Elsevier Ireland Ltd. All rights reserved.)

Purpose: To describe the results of efforts to recruit Asian Americans into longitudinal research on cognitive decline in aging., Design and Methods: Recruitment strategies include clinics for assessment of cognitive impairment at the University of California, San Francisco campus and San Francisco's Chinatown, lectures to local health care providers and community members, participation in community events, and publications in mass media., Results: Over 200 Chinese patients were evaluated in our outreach clinic. Many were primarily Chinese speaking with low levels of education. One hundred and twenty-five participants enrolled, and annual follow-up has been 88%. Among enrollees, 36% were recruited from our clinical service; 30% via word of mouth; and the rest from community lectures and events, flyers, and mass media. Participants who enrolled were relatively highly educated, tended to be interested in learning about their cognitive abilities, and were supportive of the goals of research., Implications: Despite the significant cultural and linguistic barriers, Chinese Americans can be successfully recruited into longitudinal studies of aging and cognitive impairment. Clinical services are a critical component of such an effort, and low education and other factors that may be associated with it are clear barriers to research participation.

Aim: To provide a physical exercise programme for older adults living in nursing homes., Background: Pain is common among older persons and for those already in long-term care and having difficulty in coping with pain will be at risk of further reducing their optimal independent function., Design: A quasi-experimental single group pretest-posttest design., Method: Older persons from a nursing home were invited to join an eight-week physical exercise programme. Each session lasted an hour and sessions were conducted once a week by physiotherapist and nurses. Physical exercise programme consisted of stretching, strengthening, balancing, towel dancing and self-administered massage to various acupressure points. On completion of each session, older persons were given a pamphlet with pictures to illustrate the exercise of the day and they were encouraged to practise these exercises by themselves. Outcome measures including pain intensity, range of movement, activities of daily living and mobility were collected before and after the physical exercise programme., Results: There were 75 older adult participants (57 female and 18 male, mean age 85.14 SD 5.30). Seventy-three percent (n = 55) of them had pain in the previous three months and were referred as pain group, while 25% (n = 20) were no pain group. Pain scores of 4.89 (on a 10-point scale) indicated medium pain intensity before the intervention for the pain group; the location of pain was mainly in the knee, back and shoulder. On completion of the physical exercise programme, there was a significant decrease in pain intensity to 2.89 (SD 2.14) (p < 0.01). There was a significant increase in range of movement in the neck, shoulder, back, hip and knee rotation, flex and abduction (p < 0.01). Mobility level was significantly increased post intervention, yet activities of daily living remained unchanged., Conclusions: The present study demonstrated the effectiveness of a physical exercise programme in relieving pain and enhancing functional mobility for older persons. Relevance to clinical practice.  It is important to educate older persons, especially those living in nursing homes, on the importance of engaging in regular physical exercise and maintaining mobility., (© 2011 Blackwell Publishing Ltd.)

The present study examined the effectiveness of a humor therapy program in relieving chronic pain, enhancing happiness and life satisfaction, and reducing loneliness among older persons with chronic pain. It was a quasiexperimental pretest-posttest controlled design. Older persons in a nursing home were invited to join an 8-week humor therapy program (experimental group), while those in another nursing home were treated as a control group and were not offered the program. There were 36 older people in the experimental group and 34 in the control group. Upon completion of the humor therapy program, there were significant decreases in pain and perception of loneliness, and significant increases in happiness and life satisfaction for the experimental group, but not for the control group. The use of humor therapy appears to be an effective nonpharmacological intervention. Nurses and other healthcare professionals could incorporate humor in caring for their patients.

Aims: To explore the activities of daily living and psychological well-being of older people living in nursing homes and also to examine the effectiveness of a gardening programme in enhancing socilaisation and life satisfaction, reducing loneliness and promoting activities of daily living for older people living in nursing homes., Background: Life in nursing homes can mean very limited physical and social activity, leading to further decline in function for many older people., Design: This was a quasi-experimental pre and posttest control group design., Methods: Older people from nursing homes were invited to join the eight week indoor gardening programme (experimental group), while older people in other nursing homes were treated as the control group; they received regular care without the eight week indoor gardening programme. There were 26 older people (25 female and one male; mean age 85 years) in the experimental group and 27 (20 female and seven male; mean age 82 years) in the control group. Demographic data including age, gender, educational level and financial situation were collected, in addition to information regarding life satisfaction, loneliness, physical activity and social network situation, before and after the eight week indoor gardening programme for both the experimental and control groups. Also, details of experimental group subjects' experience of the indoor gardening programme were elicited using open-ended questions., Results: There were significant improvements in life satisfaction and social network and a significant decrease in perception of loneliness for older people in the experimental group after the eight week indoor gardening programme, while the activities of daily living were unchanged for both groups after the programme., Relevance to Clinical Practice: Given the positive effects of gardening activities, it is suggested that they be promoted more widely among nursing home residents.

This study enhanced nutritional knowledge in an education program and encouraged healthy dietary habits and regular physical activity among teenagers. A total of 203 adolescents from a secondary school in Hong Kong took part in the study. Their Body Mass Index, dietary habits, and physical exercise pattern were recorded and examined before and after the health education program. The prevalence of overweight and obesity, together with the fat composition, were high among the participants before the nutrition education program. There was a marked gain in knowledge upon its completion. A follow-up action conducted 3 months later revealed positive outcomes in relation to the diet and physical activity level. The teenagers were able to take control of their health and requested the tuck shop to sell more healthy food and reduce the supply of unhealthy items. The educational initiatives in dietary habits and physical activities proved to be effective in encouraging the teenagers to eat more healthily and to adopt an active lifestyle.

The Internet is becoming the preferred place to find information. Millions of people go online in search of health and medical information. Likewise, the demand for Web-based courses is growing. This paper presents the development, utilization, and evaluation of a Web-based e-learning course for nursing students, entitled Integration of Pathophysiology into Pharmacology. The pathophysiology component included cardiovascular, respiratory, central nervous and immune system diseases, while the pharmacology component was developed based on 150 commonly used drugs. One hundred and nineteen Year 1 nursing students took part in the course. The Web-based e-learning course materials were uploaded to a WebCT for students' self-directed learning and attempts to pass two scheduled online quizzes. At the end of the semester, students were given a questionnaire to measure the e-learning experience. Their experience in the e-learning course was a positive one. Students stated that they were able to understand rather than memorize the subject content, and develop their problem solving and critical thinking abilities. Online quizzes yielded satisfactory results. In the focus group interview, students indicated that they appreciated the time flexibility and convenience associated with Web-based learning, and also made good suggestions for enhancing Web-based learning. The Web-based approach is promising for teaching and learning pathophysiology and pharmacology for nurses and other healthcare professionals.

To meet the needs of frail older people and to promote functional longevity, providing health education and disease prevention to the elderly is important. The present study describes the development, implementation, and evaluation of an e-health program for older persons. The objective of the 4-week e-health program was to improve elders' autonomous access to and use of health-related information in the form of physical exercise videography from a government-sponsored Web site. The content of the program included participants' mastery of basic computing skills and accessing and enhancing participants' interest in seeking health-related knowledge and information via the Internet. Data were collected in weeks 1 (pretest) and 4 (posttest) using questionnaires and open-ended questions. Thirty older people participated in the study (9 males, 21 females, aged 65-80 years, with the mean age of 72). Participants' mastery of basic computer operating skills increased significantly (p < 0.05); they were able to access health information via the Internet and had gained health-related knowledge by week 4 posttest (p < 0.05). The overall learning experience was positive. In conclusion, the collaboration of community partners in sponsoring a technology-based e-health program would be an effective way to provide health education to older people.

Background: Nutrition plays an important role throughout the life span. It is the interaction of nutrition and health that form part of the aging process. Nutrition affects the maintenance of physiological and biological process of aging, also, the risk of development of acute and chronic diseases., Objective: To examine dietary related behaviors and lifestyle factors among non-institutionalized older persons in a local Chinese community., Design, Setting and Participants: It was a cross-sectional qualitative descriptive design. A convenience sample of 36 older persons (mean +/- SD age, 75 +/- 7.8 years) in a community center were approached and invited to complete a questionnaire regarding their dietary-related profile and the self-perceived nutritional and health status., Results: Results showed that 40% (n=14) of the older persons lived alone and ate alone on a regular basis, taking few fruit and vegetables per day, inadequate fluid and no dairy or bean curd products, and 48% (n=17) were overweight or obese. The self-perceived nutritional status correlated directly with perceived health status, which was high., Clinical Relevance: The clinical relevance of this study is highlighted by the far from optimal dietary behaviors among this group of older persons. Nurses and health care providers working in the community should provide education on healthy diet and nutrition-related health problems, especially to older persons, for health maintenance and disease prevention.

The Internet is becoming the preferred place for finding information. Millions of people go online in search of health and medical information. Likewise, health care professionals must be able to retrieve and manage information in an efficient, effective manner. The development of health technology and informatics (HTI) has been rapid, yet little is known about the knowledge and attitudes of nursing students with regard to using HTI. Therefore, the objective of the present study was to explore nursing students' knowledge of and attitudes toward using HTI and to use an e-learning workshop to enhance the effective use of HTI. In Phase I, 115 first-year full-time nursing students were invited to complete a 13-item questionnaire regarding knowledge of and attitudes toward computer and Internet use, knowledge of HTI, and attitudes toward the future development of HTI. Participants perceived themselves to be knowledgeable in computer and Internet use, while knowledge of HTI was perceived to be low and attitudes toward the future development of HTI were generally positive. Phase II was an e-learning HTI workshop; topics included an introduction to HTI, examples of HTI in use, and the application and implementation of various HTI projects. There were 30 participants in the E-learning workshop, and their feedback was positive. Nurses and all health care professionals must be prepared to participate in the development of health technology and informatics. Teaching and learning activities should be geared toward mastery of HTI in the nursing education curriculum in order to enhance health care quality and safety.

Objectives: ABCB1 encodes the efflux transporter P-glycoprotein (P-gp), which regulates the intracellular concentration of many xenobiotics, including several HIV protease inhibitors (PIs). Exposure to some xenobiotics, such as the antibiotic rifampicin, increases P-gp expression. In the present study, we investigated the effect of the HIV PIs saquinavir and atazanavir on the expression and function of ABCB1 and P-gp in primary and cultured lymphocytes, as well as the molecular interactions between these drugs and P-gp. ABCB1 and P-gp expression and function were examined in lymphocyte samples from healthy subjects before and after atazanavir-boosted saquinavir treatment. Expression and function were also studied in CEM cells following exposure to atazanavir and saquinavir. The inhibitory effects of these drugs were investigated in ABCB1-transfected HEK293T cells., Methods: P-gp expression and function were measured by flow cytometry. ABCB1 mRNA expression was evaluated using quantitative RT-PCR., Results: There were no overall changes in ABCB1 or P-gp expression or function after saquinavir-atazanavir treatment in primary lymphocyte samples. However, there was considerable interindividual variability in baseline lymphocyte ABCB1 expression, as well as in the degree of change in ABCB1 expression after saquinavir-atazanavir administration. In cell culture, 5 microM saquinavir increased ABCB1 levels, although it did not affect P-gp expression. Atazanavir inhibited P-gp function at concentrations above therapeutic levels., Conclusions: Differences in lymphocyte ABCB1 expression, which may be caused by genetic polymorphisms in ABCB1 or its regulatory partners, are a likely cause of interindividual variation in the disposition and efficacy of clinically relevant P-gp substrates, including HIV PIs.

Objectives: To explore nursing home-related beliefs among older Hong Kong Chinese and identify strategies that make nursing homes a better place to live., Background: Increased life expectancy has markedly increased the prevalence of age-related disease and disability, which limits the self-caring ability of older persons. Nursing home placement offers one possible alternative. However, the perspectives of older persons on nursing home admission have been seriously neglected and under-reported., Methods: The research was a qualitative descriptive study. Clients of a community centre for older people were approached and invited for an interview., Results: Participants included 118 older persons (61 female and 57 male) age from 60-89 years. Ninety per cent had chronic diseases and needed regular follow-up. Half of participants had never visited a nursing home. Of them, 85% would not want to live in a nursing home upon getting old and their nursing home-related beliefs were found to be negative. Participants expressed the feeling of being abandoned by their family members, insecure and lonely regarding the nursing home placement. Living in a nursing home was considered as 'living in jail' and that their privacy would be lost. Nevertheless, positive aspects of nursing home placement were mentioned, and strategies were explored that would make nursing homes a better place for older people to live., Relevance to Clinical Practice: Positive aspects of nursing home placement need to be promoted. Nurses should be advocates for the health of the elderly, and help make nursing homes a better place to live.

The Internet is becoming a preferred place to find information. Millions of people go online in the search of health and medical information. Likewise, the demand for Web-based courses grows. This article presents the development, utilization and evaluation of a web-based pharmacology course for nursing students. The course was developed based on 150 commonly used drugs. There were 110 year 1 nursing students took part in the course. After attending six hours face to face lecture of pharmacology over three weeks, students were invited to complete a questionnaire (pre-test) about learning pharmacology. The course materials were then uploaded to a WebCT for student's self-directed learning and attempts to pass two scheduled online quizzes. At the end of the semester, students were given the same questionnaire (post-test). There were a significant increase in the understanding compared with memorizing the subject content, the development of problem solving ability in learning pharmacology and becoming an independent learner (p ,0.05). Online quizzes yielded satisfactory results. In the focused group interview, students appreciated the time flexibility and convenience associated with web-based learning, also, they had made good suggestions in enhancing web-based learning. Web-based approach is promising for teaching and learning pharmacology for nurses and other health-care professionals.

ASPIRE I and II were prospective, 3-way sequential crossover studies in healthy volunteers to compare the safety and pharmacokinetics of saquinavir/ritonavir (SQV/RTV) with saquinavir/atazanavir (SQV/ATV) administered either once daily (QD, ASPIRE I) or twice daily (BID, ASPIRE II). Treatments were separated by 10 days, and pharmacokinetic analyses were performed on days 11, 32, and 53. SQV pharmacokinetics were significantly higher when dosed with RTV compared to ATV (P < .05 for all comparisons). ATV pharmacokinetics were similar within treatment arms. ATV Cmin increased approximately 60%, and Cmax decreased approximately 35% with BID dosing compared with QD dosing. Women had higher exposure for all 3 protease inhibitors (PIs) compared with men after adjusting for weight. Adverse effects were primarily gastrointestinal-related with SQV/RTV and hyperbilirubinemia with SQV/ATV. Although SQV plasma concentrations were higher when coadministered with RTV, a combination of SQV/ATV administered BID may be a viable alternative in HIV-infected, PI-naive subjects intolerant to RTV.

With increasing life expectancy, the incidence of chronic illness and chronic pain also increase. Chronic pain robs older people of their quality of life, and limits functional mobility and ambulation, which leads to muscle atrophy. Older people are often reluctant to request pain relief, attempting to endure pain as a "normal" part of ageing. Innovative non-pharmacological interventions in pain management are appealing. In this study, affective images and pictures were used in 15 elderly patients (12 female and three male) in chronic pain who needed to perform stretching and standing exercises in their physiotherapy sessions. Pain scores were measured by the Visual Analogue Scale (VAS), and health-related quality of life was measured by the Medical Outcomes Study Short Form 36 (SF-36). VAS and SF-36 were administered in weeks 1 and in 6. Pain scores were measured during physiotherapy session in the following weeks. There was a significant decreased in VAS from week 1 to week 6 (t = 3.607; df = 14; p < 0.05). Also, a significant decrease in VAS occurred when the patients were watching affective pictures while performing the physiotherapy exercise in weeks 2 and 3, but not in weeks 4 and 5. SF-36 increased in week 6, which indicated an increase in health-related quality of life, though not statistically significant. Affective images and pictures appear to be an effective non-pharmacological intervention in pain management for the older person.
