Vitamin D deficiency is common and may contribute to osteopenia, osteoporosis and falls risk in the elderly. Screening for vitamin D deficiency is important in high-risk patients, especially for patients who suffered minimal trauma fractures. Vitamin D deficiency should be treated according to the severity of the deficiency. In high-risk adults, follow-up serum 25-hydroxyvitamin D concentration should be measured 3–4 months after initiating maintenance therapy to confirm that the target level has been achieved. All patients should maintain a calcium intake of at least 1,000 mg for women aged ≤ 50 years and men ≤ 70 years, and 1,300 mg for women > 50 years and men > 70 years.  相似文献

BackgroundThere is a lack of evidence regarding the impact of changes in waist circumference on disability among older populations in low- and middle-income countries (LMICs). This research examines the association between changes in waist circumference with disability in the older populations of Indonesia, and whether the associations are dependent on wealth or baseline abdominal obesity levels.MethodsIn 2007 the INDEPTH-WHO Study on global AGEing and adult health (SAGE) was conducted among 11,753 individuals aged 50 years and older in Purworejo District, Central Java Province, Indonesia. Of these, a total of 8,089 were followed up in 2010. On both occasions, individuals’ waist circumferences were measured and the 12-item version of the WHO Disability Assessment Schedule version 2 (WHODAS-II) was implemented to measure disability.ResultsA significant positive association was observed between waist circumference and disability at the baseline (β = 0.066; p < 0.001), and between the increase in waist circumference and the level of disability during the three-year follow-up period (β = 0.094; p < 0.001) after adjusting for baseline variables. This association was also significant among the poor, non-obese men, as well as poor and rich obese women. Among the non-obese women, a decrease in waist circumference was associated with more disabilities.ConclusionsAn increase in waist circumference is associated with increased disability among older people in Purworejo, Indonesia. Health promotion programmes aiming to prevent obesity could have positive effects in preventing and reducing disability among older adults.  相似文献

ObjectiveTo describe a systematic process of transforming paper registers into a digital system optimized to enhance service provision and fulfil reporting requirements.MethodsWe designed a formative study around primary health workers providing reproductive, maternal, newborn and child health services in three countries in Bangladesh, Indonesia and Pakistan. The study ran from November 2014 to June 2018. We developed a prototype digital application after conducting a needs assessment of health workers’ responsibilities, workflows, routine data requirements and service delivery needs. Methods included desk reviews, focus group discussions, in-depth interviews; data mapping of paper registers; observations of health workers; co-design workshops with health workers; and usability testing. Finally, we conducted an observational feasibility assessment to monitor uptake of the application.FindingsResearchers reviewed a total of 17 paper registers across the sites, which we transformed into seven modules within a digital application running on mobile devices. Modules corresponded to the services provided, including household enumeration, antenatal care, family planning, immunization, nutrition and child health. A total of 65 health workers used the modules during the feasibility assessment, and average weekly form submissions ranged from 8 to 234, depending on the health worker and their responsibilities. We also observed variability in the use of modules, requiring consistent monitoring support for health workers.ConclusionLessons learnt from this study shaped key global initiatives and resulted in a software global good. The deployment of digital systems requires well-designed applications, change management and strengthening human resources to realize and sustain health system gains.  相似文献

This systematic review and meta‐analysis aimed to study the efficacy and safety of chamomile for the treatment of state anxiety, generalized anxiety disorders (GADs), sleep quality, and insomnia in human. Eleven databases including PubMed, Science Direct, Cochrane Central, and Scopus were searched to retrieve relevant randomized control trials (RCTs), and 12 RCTs were included. Random effect meta‐analysis was performed by meta package of R statistical software version 3.4.3 and RevMan version 5.3. Our meta‐analysis of three RCTs did not show any difference in case of anxiety (standardized mean difference = ?0.15, 95% CI [?0.46, 0.16], P = 0.4214). Moreover, there is only one RCT that evaluated the effect of chamomile on insomnia and it found no significant change in insomnia severity index (P > 0.05). By using HAM‐A scale, there was a significant improvement in GAD after 2 and 4 weeks of treatment (mean difference = ?1.43, 95% CI [?2.47, ?0.39], P = 0.007), (MD = ?1.79, 95% CI [?3.14, ?0.43], P = 0.0097), respectively. Noteworthy, our meta‐analysis showed a significant improvement in sleep quality after chamomile administration (standardized mean difference = ?0.73, 95% CI [?1.23, ?0.23], P < 0.005). Mild adverse events were only reported by three RCTs. Chamomile appears to be efficacious and safe for sleep quality and GAD. Little evidence is there to show its effect on anxiety and insomnia. Larger RCTs are needed to ascertain these findings.  相似文献

Background

The high cost and low level of cancer survival urge the finding of new drugs having better mechanisms. There is a high trend of patients to be “back to nature” and use natural products as an alternative way to cure cancer. The fact is that some of available anticancer drugs are originated from plants, such as taxane, vincristine, vinblastine, pacitaxel. Curcumin (diferuloylmethane), a dietary pigment present in Curcuma longa rizhome is reported to induce cell cycle arrest in some cell lines. Other study reported that genistein isolated from Glycine max seed inhibited phosphorylation of cdk1, gene involved during G2/M transition and thus could function as G2 checkpoint abrogator. The inhibition of cdk1 phosphorylation is one of alternative strategy which could selectively kill cancer cells and potentially be combined with DNA damaging agent such as curcumin.

Methods

T47D cell line was treated with different concentrations of curcumin and genistein, alone or in combination; added together or with interval time. Flow Cytometry and MTT assay were used to evaluate cell cycle distribution and viability, respectively. The presence of apoptotic cells was determined using acridine orange-ethidium bromide staining.

Results

In this study curcumin induced G2 arrest on p53 deficient T47D cells at the concentration of 10 μM. Increasing concentration up to 30 μM increased the number of cell death. Whilst genistein alone at low concentration (≤10 μM) induced cell proliferation, addition of genistein (20 μM) 16 h after curcumin resulted in more cell death (89%), 34% higher than that administered at the same time (56%). The combination treatment resulted in apoptotic cell death. Combining curcumin with high dose of genistein (50 μM) induced necrotic cells.

Conclusions

Genistein increased the death of curcumin treated T47D cells. Appropriate timing of administration and concentration of genistein determine the outcome of treatment and this method could potentially be developed as an alternative strategy for treatment of p53 defective cancer cells.  相似文献

BackgroundConventional Web-based search engines may be unusable by individuals with low health literacy for finding health-related information, thus precluding their use by this population.ObjectiveWe describe a conversational search engine interface designed to allow individuals with low health and computer literacy identify and learn about clinical trials on the Internet.MethodsA randomized trial involving 89 participants compared the conversational search engine interface (n=43) to the existing conventional keyword- and facet-based search engine interface (n=46) for the National Cancer Institute Clinical Trials database. Each participant performed 2 tasks: finding a clinical trial for themselves and finding a trial that met prespecified criteria.ResultsResults indicated that all participants were more satisfied with the conversational interface based on 7-point self-reported satisfaction ratings (task 1: mean 4.9, SD 1.8 vs mean 3.2, SD 1.8, P<.001; task 2: mean 4.8, SD 1.9 vs mean 3.2, SD 1.7, P<.001) compared to the conventional Web form-based interface. All participants also rated the trials they found as better meeting their search criteria, based on 7-point self-reported scales (task 1: mean 3.7, SD 1.6 vs mean 2.7, SD 1.8, P=.01; task 2: mean 4.8, SD 1.7 vs mean 3.4, SD 1.9, P<.01). Participants with low health literacy failed to find any trials that satisfied the prespecified criteria for task 2 using the conventional search engine interface, whereas 36% (5/14) were successful at this task using the conversational interface (P=.05).ConclusionsConversational agents can be used to improve accessibility to Web-based searches in general and clinical trials in particular, and can help decrease recruitment bias against disadvantaged populations.  相似文献

Aims Opioid substitution treatment has been studied extensively in industrialized countries, but there are relatively few studies in developing/transitional countries. The aim of this study was to examine the effectiveness of opioid substitution treatment (OST) in less resourced countries. Design Longitudinal cohort study. Setting Purposively selected OST sites in Asia (China, Indonesia, Thailand), Eastern Europe (Lithuania, Poland, Ukraine), the Middle East (Iran) and Australia. Participants Seven hundred and twenty-six OST entrants. Measurements Participants were interviewed at treatment entry, 3 and 6 months. Standardized instruments assessed drug use, treatment history, physical and psychological health, quality of life, criminal involvement, blood-borne virus (BBV) risk behaviours and prevalence of human immunodeficiency virus (HIV) and hepatitis C. Findings Participants were predominantly male, aged in their early 30s and had attained similar levels of education. Seroprevalence rates for HIV were highest in Thailand (52%), followed by Indonesia (28%) and Iran (26%), and lowest in Australia (2.6%). Treatment retention at 6 months was uniformly high, averaging approximately 70%. All countries demonstrated significant and marked reductions in reported heroin and other illicit opioid use; HIV (and other BBV) exposure risk behaviours associated with injection drug users (IDU) and criminal activity, and demonstrated substantial improvement in their physical and mental health and general wellbeing over the course of the study. Conclusions OST can achieve similar outcomes consistently in a culturally diverse range of settings in low- and middle-income countries to those reported widely in high-income countries. It is associated with a substantial reduction in HIV exposure risk associated with IDU across nearly all the countries. Results support the expansion of opioid substitution treatment.  相似文献

PURPOSE: To study whether topical ibopamine effectively increases the intraocular pressure in patients with ocular hypotony after vitreoretinal surgery, uveitis, or penetrating trauma. DESIGN: A prospective randomized, double-blind, placebo controlled, crossover study. METHODS: In ten patients with ocular hypotony, an ibopamine 2% solution or placebo eyedrop was administered at 8 am and frequent applanation tonometry was performed during 10 hours on 2 days, 2 weeks apart. RESULTS: The mean IOP integral after administration of ibopamine was 2.4 mm Hg higher (95% CI for median difference in AUC over 480 minutes [P = .010]) compared with placebo. CONCLUSIONS: The results of the study show that an ibopamine 2% eyedrop twice a day may increase the IOP for a period of over 8 hours in patients with hypotony.  相似文献
