Fracture liaison services for osteoporosis in the Asia-Pacific region: current unmet needs and systematic literature review.

The analysis aimed to identify the treatment gaps in current fracture liaison services (FLS) and to provide recommendations for best practice establishment of future FLS across the Asia-Pacific region. The findings emphasize the unmet need for the implementation of new programs and provide recommendations for the refinement of existing ones. The study's objectives were to evaluate fracture liaison service (FLS) programs in the Asia-Pacific region and provide recommendations for establishment of future FLS programs. A systematic literature review (SLR) of Medline, PubMed, EMBASE, and Cochrane Library (2000-2017 inclusive) was performed using the following keywords: osteoporosis, fractures, liaison, and service. Inclusion criteria included the following: patients ≥ 50 years with osteoporosis-related fractures; randomized controlled trials or observational studies with control groups (prospective or retrospective), pre-post, cross-sectional and economic evaluation studies. Success of direct or indirect interventions was assessed based on patients' understanding of risk, bone mineral density assessment, calcium intake, osteoporosis treatment, re-fracture rates, adherence, and mortality, in addition to cost-effectiveness. Overall, 5663 unique citations were identified and the SLR identified 159 publications, reporting 37 studies in Asia-Pacific. These studies revealed the unmet need for public health education, adequate funding, and staff resourcing, along with greater cooperation between departments and physicians. These actions can help to overcome therapeutic inertia with sufficient follow-up to ensure adherence to recommendations and compliance with treatment. The findings also emphasize the importance of primary care physicians continuing to prescribe treatment and ensure service remains convenient. These findings highlight the limited evidence supporting FLS across the Asia-Pacific region, emphasizing the unmet need for new programs and/or refinement of existing ones to improve outcomes. With the continued increase in burden of fractures in Asia-Pacific, establishment of new FLS and assessment of existing services are warranted to determine the impact of FLS for healthcare professionals, patients, family/caregivers, and society.

Effect of soil fortified by polyurethane foam on septic tank effluent treatment.

Fortified soil was made up of a mixture at a mass ratio 4/1000-6/1000 of sponge and natural soil according to the results of column experiment. The fortified soil had bigger porosity and higher hydraulic conductivity than the natural soil. The columns packed with 900 mm of the fortified soil endured a flow rate equivalent to 100 L/m(2)/d of septic tank effluent and the average chemical oxygen demand, nitrogen, and phosphorus removal rates were around 92%, 75% and 96%, respectively. After 100 weeks of operation, the saturated hydraulic conductivity of the fortified soil kept higher than 0.2 m/d. The bigger porosity of sponge improved the effective porosity, and the bigger specific surface area of sponge acted as an ideal support for biomat growth and ensured the sewage treatment performance of the fortified soil. The comparable performance was due to a similar and sufficient degree of soil clogging genesis coupled with bioprocesses that effectively purified the septic tank effluent given the adequate retention times.

Effects of luteolin on arylamine N-acetyltransferase activity in rat blood and liver.

In this study we investigated inhibition of Arylamine N-acetyltransferase (NAT) activity in rat blood and liver tissue cytosols by luteolin. Using high-performance liquid chromatography, NAT activity for acetylation of 2-aminofluorene and remaining unacetylated 2-aminofluorene were examined. The NAT activity in rat blood and liver tissue was inhibited by luteolin in a dose-dependent manner: higher concentrations of luteolin in the reaction resulted in greater inhibition of NAT activities in both examined tissues. The data also indicated that luteolin decreased apparent Km and Vmax of NAT enzymes from rat blood and liver tissue cytosols. This report is the first demonstration that luteolin can affect rat blood and liver tissue NAT activity.

Influence of arginine dietary supplementation on healing colonic anastomosis in the rat.

INTRODUCTION: This study sought to determine whether dietary arginine influences colonic anastomotic healing in the rat model. METHODS: Three groups of 42 Sprague-Dawley rats were fed 0, 1, and 3 percent arginine diets for three preoperative and three postoperative days. Animals underwent transection of the transverse colon with hand-sewn anastomosis. Subgroups of 14 animals in each dietary group were killed on postoperative Days 6, 10, or 14, and bursting pressures, histologic inflammation, and collagen content were compared. RESULTS: Mean anastomotic bursting pressures on postoperative Day 6 were lower for the 0 percent arginine group than the 1 and 3 percent arginine groups (mean +/- standard error of the mean = 134+/-6 mm Hg, 164+/-7 mm Hg, and 166+/-7 mm Hg, respectively; P<0.0005). On Days 10 and 14, no significant differences in bursting pressures were noted between arginine diets. Mean bursting pressures on postoperative Day 6 (155+/-4 mm Hg) were significantly lower than on Days 10 (204+/-5 mm Hg) and 14 (217+/-6 mm Hg; P<0.001) for all arginine diets. Microscopic evaluation of the anastomoses did not show significant differences in inflammation or collagen content between arginine diets. Collagen content in all dietary groups peaked at Day 10. CONCLUSIONS: Perioperative arginine deficiency in the rat model is associated with impaired anastomotic healing during the first week, as reflected by lower bursting pressures. Arginine supplementation to 3 percent does not improve bursting pressures above those found in the usual 1 percent arginine diet at 6, 10, or 14 days. Bursting pressures plateau by Day 10 regardless of perioperative dietary arginine, whereas collagen content peaks at Day 10 after six-day perioperative arginine diet manipulation.

Mental health issues for Asian Americans.

One of fastest-growing population groups in recent decades, Asian Americans represent a vastly diversified and rich mixture of cultures, languages, beliefs, and practices, many of which differ widely from those of European Americans. As immigrants, Asian Americans have experienced and continue to experience various emotional and behavioral problems. However, they tend to underuse existing services except those that are culturally appropriate and linguistically compatible. Misdiagnosis frequently occurs, and the existence of culture-bound syndromes points to a lack of precise correspondence between indigenous labels and established diagnostic categories. Due to Asian traditions of viewing the body and mind as unitary rather than dualistic, patients tend to focus more on physical discomforts than emotional symptoms, leading to an overrepresentation of somatic complaints. Traditional practices and healing methods are frequently used to alleviate distress both before and after patients and their family members approach the conventional mental health care system. Help seeking typically is a family venture. Asian patients respond well to highly structured therapeutic interventions such as those used in behavioral, cognitive, and interpersonal models. When applying pharmacotherapy, clinicians should pay attention to Asians' unique responses to psychotropics, especially in regard to dosage requirements and side effects. Research in this area as well as on other important issues is in the early stage of development.

Hwa-byung. A community study of Korean Americans.

One hundred nine Korean American community subjects were interviewed regarding their experiences with hwa-byung (HB), a Korean folk illness label commonly used by Koreans with a myriad of physiological and psychological complaints. During these interviews, standard instruments were also used to assess their depressive and somatic symptoms. The results indicated that a relatively high proportion (12%) of the subjects labeled themselves as having suffered from HB. While no apparent sociodemographic differences were found between HB and non-HB subjects, significantly more HB subjects fulfilled the diagnosis of DSM-III major depression and also had previous diagnoses of depression. The HB subjects also had significantly higher scores for the total, depressive, and somatic subscales and 16 of the 20 individual items of the Center for Epidemiologic Studies-Depression Scale. These data confirm previous observations of substantial overlap between HB and DSM-III major depression among Koreans and Korean Americans, and suggest that HB may be a culturally patterned way of expression for Koreans experiencing major depression and related conditions. The clinical and theoretical implications of these findings are also discussed.

Pharmacotherapy for southeast Asian psychiatric patients.

Refugees have been demonstrated to be at high risk for developing major depressive and posttraumatic stress disorders, but are often not able to benefit from modern advances in psychopharmacology. Besides difficulties in cross-cultural psychiatric diagnosis, problems also arise from cultural differences in the expectation of drug effects and in compliance. Recent evidence has suggested that pharmacokinetic and pharmacodynamic profiles of various psychotropic medications may be different in Asians than in non-Asian patients, leading to differences in dosage requirements and side effect profiles. These issues and their relevance to the care of refugee patients are reviewed.

Hwa-Byung: a Korean culture-bound syndrome?

The author reports three cases of Hwa-Byung, a Korean folk illness ordinarily understood by patients and families to be a physical affliction despite the fact that its manifestations include both physiological and psychological symptoms. In addition, the patient often recognizes interpersonal conflicts and anger as precipitating factors. In the three cases reported, the patients also identified an epigastric mass that was not present on physical examination. Symptoms were accompanied by a fear of impending death that was not easily dispelled by medical reassurance. The author discusses the role of depression in the symptom formation of Hwa-Byung as well as the treatment implications.
