Background: Guidelines recommend multifactorial intervention programmes to prevent falls in older adults but there are few randomised controlled trials in a real life health care setting. We describe the rationale, intervention, study design, recruitment strategies and baseline characteristics of participants in a randomised controlled trial of a multifactorial falls prevention programme in primary health care.

Geological carbon dioxide storage (CCS) has the potential to make a significant contribution to the decarbonisation of the UK. Amid concerns over maintaining security, and hence diversity, of supply, CCS could allow the continued use of coal, oil and gas whilst avoiding the CO 2 emissions currently associated with fossil fuel use. This project has explored some of the geological, environmental, technical, economic and social implications of this technology. The UK is well placed to exploit CCS with a large offshore storage capacity, both in disused oil and gas fields and saline aquifers. This capacity should be sufficient to store CO 2 from the power sector (at current levels) for a least one century, using well understood and therefore likely to be lower-risk, depleted hydrocarbon fields and contained parts of aquifers. It is very difficult to produce reliable estimates of the (potentially much larger) storage capacity of the less well understood geological reservoirs such as non-confined parts of aquifers. With the majority of its large coal fired power stations due to be retired during the next 15 to 20 years, the UK is at a natural decision point with respect to the future of power generation from coal; the existence of both national reserves and the infrastructure for receiving imported coal makes clean coal technology a realistic option. The notion of CCS as a 'bridging' or 'stop-gap' technology (i.e. whilst we develop 'genuinely' sustainable renewable energy technologies) needs to be examined somewhat critically, especially given the scale of global coal reserves. If CCS plant is built, then it is likely that technological innovation will bring down the costs of CO 2 capture, such that it could become increasingly attractive. As with any capitalintensive option, there is a danger of becoming 'locked-in' to a CCS system. The costs of CCS in our model for UK power stations in the East Midlands and Yorkshire to reservoirs in the North Sea are between £25 and £60 per tonne of CO 2 captured, transported and stored. This is between about 2 and 4 times the current traded price of a tonne of CO 2 in the EU Emissions Trading Scheme. In addition to the technical and economic requirements of the CCS technology, it should also be socially and environmentally acceptable. Our research has shown that, given an acceptance of the severity and urgency of addressing climate change, CCS is viewed favourably by members of the public, provided it is adopted within a portfolio of other measures. The most commonly voiced concern from the public is that of leakage and this remains perhaps the greatest uncertainty with CCS. It is not possible to make general statements concerning storage security; assessments must be site specific. The impacts of any potential leakage are also somewhat uncertain but should be balanced against the deleterious effects of increased acidification in the oceans due to uptake of elevated atmospheric CO 2 that have already been observed. Provided adequate long term monitoring can be ensured, any leakage of CO 2 from a storage site is likely to have minimal localised impacts as long as leaks are rapidly repaired. A regulatory framework for CCS will need to include risk assessment of potential environmental and health and safety impacts, accounting and 1 monitoring and liability for the long term. In summary, although there remain uncertainties to be resolved through research and demonstration projects, our assessment demonstrates that CCS holds great potential for significant cuts in CO 2 emissions as we develop long term alternatives to fossil fuel use. CCS can contribute to reducing emissions of CO 2 into the atmosphere in the near term (i.e. peak-shaving the future atmospheric concentration of CO 2 ), with the potential to continue to deliver significant CO 2 reductions over the long term.

Seventy-six percent of 65 psychotherapy cases seen in a child guidance clinic either did not change or improved following a mandated report of suspected child abuse. In a significant minority of cases, the therapy relationship deteriorated when the report was made about a client in treatment, and improved when the report was made about a third party not in treatment.

The purpose of this paper is to present a method of identifying key risks during IT audit of an organization, regardless of the organization activity, and presenting the impact of the risks identified on the audit methodology. Our main focus is reducing the risk identification during phase during an audit mission. Due to the fast changing economy, the need for

, the number of elderly Hispanics and Asians living in US nursing homes grew by 54.9 percent and 54.1 percent, respectively, while the number of elderly black residents increased 10.8 percent. During the same period, the number of white nursing home residents declined 10.2 percent. These shifts have been driven in part by changing demographics, especially the fast growth of older minority populations. However, the numbers of minority residents in nursing homes increased more rapidly than the minority population overall, even in areas with high concentrations of minority populations. Thus, these results may indicate unequal minority access to home and communitybased alternatives, which are generally preferred for long-term care. When designing initiatives to balance institutional and noninstitutional long-term care, policy makers should take steps to reduce racial and ethnic disparities.

Displaced four-part fractures comprise 2-10 % of all proximal humeral fractures. The optimal treatment is unclear and randomised trials are needed. The conduct and interpretation of such trials is facilitated by a reproducible fracture classification. We aimed at quantifying observer agreement on the classification of displaced four-part fractures according to the Neer system. Published and unpublished data from five observer studies were reviewed. Observers agreed less on displaced four-part fractures than on the overall Neer classification. Mean kappa values for interobserver agreement ranged from 0.16 to 0.48. Specialists agreed slightly more than fellows and residents. Advanced imaging modalities (CT and 3D CT) seemed to contribute more to classification of displaced four-part patterns than in less complex fracture patterns. Low observer agreement may challenge the clinical approach to displaced four-part fractures and poses a problem for the interpretation and generalisation of results from future randomised trials.

Conventional methods to detect and assess the viability of plant pathogenic bacteria are usually based on plating assays or serological techniques. Plating assays provide information about the number of viable cells, expressed as colony-forming units, but are time-consuming and laborious. Serological methods, such as the enzyme-linked immunosorbent assay (ELISA) and immunofluorescence microscopy (IF), can be performed in a shorter timespan than most plating assays, but they do not discriminate between live and dead cells. Flow cytometry (FCM) in combination with fluorescent probe technology is a rapid, sensitive, and quantitative technique to detect microorganisms and assess their viability. Quantitative information on the presence and viability of plant pathogenic microorganisms is valuable for risk assessment regarding disease transmission and disease development. FCM has been applied successfully in the fields of food microbiology, veterinary science, and medical research to dete...

International standards highlight the steps required by risk assessment and involving first hazard identification, then risk evaluation and finally, if necessary, risk assessment. To check approach appropriateness to "risk evaluation" from manual patient handling through MAPO, a cross study was carried out in view of checking relationship between this new risk assessment model and occurrence of acute low back pain. After proper training the MAPO screening method was assessed in 31 wards, 411 exposed subjects of geriatric hospitals. At the same time health data were collected on occurrence of low back pain episodes during the last year both in the exposed subjects' group and the external reference group (n�237). Risk and clinical assessment data were tutored and checked by EPM research unit. The logistic analysis was used as a method to evaluate the relationship between risk index and acute low back pain. Investigating relationship between acute low back pain episodes a...

This review summarizes the current state-of-the-art regarding the endovascular management of acute ischemic stroke. Beginning with intravenous tissue plasminogen activator, this paper traces the gradual shift of systemic thrombolysis from a competing to complementary treatment modality. Intra-arterial thrombolysis, mechanical thrombectomy with the Merci (Concentric Medical, Mountain View, California) and Penumbra (Penumbra, Inc., Alameda, California) systems, angioplasty, primary intracranial stenting, and emerging stentriever devices are sequentially reviewed. Ultimately, this paper lays the foundation for current endovascular stroke management and considers future areas of progress and research.

Background Rickets affects young infants and toddlers. However, there is a paucity of literature regarding the types of fractures that occur in rachitic patients. Objective To evaluate the age of patients at which radiographically evident rickets occurs, and to characterize the age incidence and fractures that are observed in infants and toddlers with radiographically evident rickets. Materials and methods A retrospective study of children younger than 24 months was performed. Clinical data and radiographs were reviewed. Radiographs obtained within 1 month of the diagnosis were evaluated for the presence or absence of osteopenia, presence or absence of fraying–cupping, and presence and characterization of fractures. Results After exclusion criteria were applied, 45 children were included in the study. Children with rickets evident by radiograph were in the age range of 2–24 months. Fractures were present in 17.5% of the study group, exclusively in mobile infants and toddlers. Fracture types included transverse long bone fractures, anterior and anterior-lateral rib fractures, and metaphyseal fractures. All fractures occurred exclusively in patients with severe, overtly evident rickets. Conclusion Fractures occur in older infants and toddlers with overt rickets and can be seen by radiograph. Fractures do not resemble high-risk non-accidental trauma fractures.

The application of chemical-specific toxicokinetic or toxicodynamic data to address interspecies differences and human variability in the quantification of hazard has potential to reduce uncertainty and better characterize variability compared with the use of traditional default or categorically-based uncertainty factors. The present review summarizes the state-of-the-science since the introduction of the World Health Organization/International Programme on Chemical Safety (WHO/IPCS) guidance on chemical-specific adjustment factors (CSAF) in 2005 and the availability of recent applicable guidance including the WHO/IPCS guidance on physiologically-based pharmacokinetic (PBPK) modeling in 2010 as well as the U.S. EPA guidance on data-derived extrapolation factors in 2014. A summary of lessons learned from an analysis of more than 100 case studies from global regulators or published literature illustrates the utility and evolution of CSAF in regulatory decisions. Challenges in CSAF dev...

Background: The incidence of residual ventricular septal defects (VSDs) after surgery is 5-25%. Redo surgery is associated with higher risks. Methods: Between January 2000 to December 2008, 170 patients underwent percutaneous VSD closure in our centre: 22(16M) of these had 23 closures for residual VSDs. Median age was 32.5 yrs (1.4-79). All patients had echocardiographic signs of left ventricle volume overload (Q p /Q s ! 1.5). Nine patients had previous VSD closure, 6 tetralogy of Fallot repair, and 7, other procedures. There were 15 muscular, 6 perimembranous and 2 apical VSDs. Results: Amplatzer VSD devices were used in all. Median VSD size was 8 mm (4.3-16). Median fluoroscopy time was 33 minutes (15-130). There were three adverse events: 1 ventricular fibrillation requiring DC cardioversion; 1 transient complete atrio-ventricular block reverting to sinus rhythm at 24-hours; one patient had transient atrial flutter during the procedure. All procedures were successful; no additional procedures were required. Trivial residual shunts were seen in 3 patients at follow-up. There were no late events. One patient experienced arrhythmic death 5-yrs after procedure. One patient was reoperated due to dehiscence of VSD patch 2-yrs after the second successful percutaneous closure. Conclusions: Transcatheter closure of postsurgical residual VSD is safe and efficacious management option and obviates the need for further surgery and by-pass. V C 2009 Wiley-Liss, Inc.

Attention-deficit/hyperactivity disorder (ADHD) is the most common neurobehavioral disorder of childhood and can profoundly affect the academic achievement, well-being, and social interactions of children; the American Academy of Pediatrics first published clinical recommendations for the diagnosis and evaluation of ADHD in children in 2000; recommendations for treatment followed in 2001.

A construction superintendent's ability to recognize hazards and to perceive and assess risk is an essential skill for maintaining safe conditions on their construction sites. In a study that aimed to explore the degree to which construction superintendents are aware of hazards and how well they perceive the associated risks, 61 subjects were asked to identify the hazards in a typical construction project, to assess their risk level, and to estimate the probability and the severity of possible accidents. Some subjects were presented with photographs and construction documents, while others toured a virtual construction site using a 3-sided virtual reality CAVE. The method allowed both for analysis of differences in perception and assessment between distinct populations and for evaluation of the effectiveness of the virtual environment in demonstrating hazardous situations. Results show that construction superintendents with many years of experience are unable to identify all of the hazards in their work environment, and that there are important discrepancies between the way they assess risk levels and the way most formal safety risk assessment methods rate risk levels. Most subjects in the virtual environment assessed higher risk levels to hazards caused by moving equipment. They also identified more hazards correctly than the subjects who studied photographs and documents. Of primary concern is the apparent lack of correlation between hours of safety training and work experience on the one hand, and hazard identification and perception skills on the other hand.

BACKGROUND CONTEXT: Optimal treatment of nonmalignant chronic spinal disorders (CSDs) may require the use of one or more nonopioid psychotropic medications. Vast research literature has documented high rates of psychiatric disorders in patients with CSDs. Psychotropic medications are one type of effective treatment for these disorders. Many medications of this type are also used as adjuvants to primary analgesic medications. PURPOSE: Physicians treating CSDs may have little training and experience in prescribing psychotropic medications. Further, they may possess limited information about the efficacy of these types of medications in treating psychiatric disorders comorbid with CSDs or as adjunctive analgesics. Because of the wide variety (antidepressants, anxiolytics, sleep-promoting agents, anticonvulsants, neuroleptics, muscle relaxants) and numerous indications for psychiatric medications, a concise review of the use of psychotropic medications with CSD patients is offered for the spine specialist. STUDY DESIGN: A systematic review of the contemporary English literature on psychotropic medications in the CSD population. METHODS: A computerized search of MEDLINE was performed on all English literature published from 1982 to August 2002. RESULTS: Psychotropic medications have been found to be very efficacious in the large subgroup of patients with CSDs with psychiatric comorbidity, particularly patients with the common constellation of depression, anxiety, excessive somatic complaints, insomnia and irritability. Although the type of medication indicated depends on the particular psychiatric syndrome(s), antidepressants have been found to be extremely useful with the constellation described above. There is less evidence to support the use of nonopioid psychotropic medications in the treatment of nociceptive pain, although clinical experience indicates that some individuals demonstrate a marked analgesic response. Research support for the efficacy of particular psychotropic medications in treating neuropathic pain is stronger, although more controlled research is clearly needed. CONCLUSIONS: Psychotropic medications are extremely useful in the treatment of psychiatric disorders comorbid with CSDs and modestly useful as analgesic adjuvants, particularly with pain of neuropathic etiology. Familiarity with these medications will aid the primary treating physician in optimizing outcomes in this difficult group of patients. Ć

Cardiovascular risk is poorly managed in women, especially during the menopausal transition when susceptibility to cardiovascular events increases. Clear gender differences exist in the epidemiology, symptoms, diagnosis, progression, prognosis, and management of cardiovascular risk. Key risk factors that need to be controlled in the peri-menopausal woman are hypertension, dyslipidaemia, obesity, and other components of the metabolic syndrome, with the avoidance and careful control of diabetes. Hypertension is a particularly powerful risk factor and lowering of blood pressure is pivotal. Hormone replacement therapy is acknowledged as the gold standard for the alleviation of the distressing vasomotor symptoms of the menopause, but the findings of the Women's Health Initiative (WHI) study generated concern for the detrimental effect on cardiovascular events. Thus, hormone replacement therapy cannot be recommended for the prevention of cardiovascular disease. Whether the findings of WHI in older post-menopausal women can be applied to younger peri-menopausal women is unknown. It is increasingly recognized that hormone therapy is inappropriate for older post-menopausal women no longer displaying menopausal symptoms. Both gynaecologists and cardiovascular physicians have an important role to play in identifying peri-menopausal women at risk of cardiovascular morbidity and mortality and should work as a team to identify and manage risk factors such as hypertension.

Purpose: A number of studies have underlined a 10-20% prevalence of complicated grief (CG) among caregivers of cancer patients. The study aimed at examining the relationship between pre-loss criteria for CG and post-loss diagnosis of CG and at evaluating the validity and factor structure of a predictive tool, the Inventory of Complicated Grief (ICG), in order to identify the risk of developing CG in a sample of Italian caregivers. Methods: Sixty family members of terminally ill patients admitted to hospice and receiving a Palliative Prognostic Score (PaP) predictive 30 day survival time o30% completed the Pre-Death ICG (ICG-PL) (T0). Family members were met again 6 months after the death of their loved one (T1) and submitted to the interview for Complicated Grief (Post-loss interview-PLI). Results: Caseness for CG was shown in 18.3% of caregivers at T1. ICG-PL score (T0) were higher among those who developed CG at T1 than non-cases. A cut off score Z49 on the ICG-PL (AUC ¼ 0.98) maximized sensitivity (92%) and specificity (98%) on caseness at T1. Pre-loss criteria related to traumatic distress, separation distress and emotional symptoms in general were significantly related to a post-loss diagnosis of CG, while no effect was shown on duration of pre-loss distress. Conclusions: The use of short screening tools, like the ICG-PL, may help health care professionals to identify subjects at risk for CG.

In mainstream offender samples, several risk assessments have been evaluated for predictive validity. This study extends this work to male offenders with intellectual disabilities. Participants from high-, medium-, and low-security settings, as well as community settings, were compared on a range of risk assessments. The Violence Risk Appraisal Guide, HCR-20-Historical Scale, the Risk Matrix 2000-C (combined risk), and the Emotional Problems Scales-Internalising discriminated between groups, with participants from high security having higher scores than those in medium security, who had higher scores than those in the community. The Violence Risk Appraisal Guide, all HCR-20 scales, the Short Dynamic Risk Scale, and the Emotional Problems Scales (Internalising and Externalising) showed significant areas under the curve for the prediction of violence. The Static-99 showed a significant area under the curve for the prediction of sexual incidents. The discussion reviews the value of these various scales to intellectual disability services. Lindsay et al. / Risk Assessment in Offenders With Intellectual Disability 91 F rom its early beginnings, when the variables relating to risk assessment were first outlined , the field of risk assessment has developed considerably in the last 15 years. A number of assessments have been produced for the prediction of violent and sexual incidents, and studies have compared the relative effectiveness of a range of instruments. The Violence Risk Appraisal Guide (VRAG; and the Sex Offender Risk Appraisal Guide (SORAG; are perhaps the most widely researched actuarial assessments in existence. Of the several studies comparing the predictive accuracy of risk assessment instruments on a range of databases, most employ either the VRAG or the SORAG as a comparator.

We consider the problem of combining opinions from different experts in an explicitly model-based way to construct a valid subjective prior in a Bayesian statistical approach. We propose a generic approach by considering a hierarchical model accounting for various sources of variation as well as accounting for potential dependence between experts. We apply this approach to two problems. The first problem deals with a food risk assessment problem involving modelling dose-response for Listeria monocytogenes contamination of mice. Two hierarchical levels of variation are considered (between and within experts) with a complex mathematical situation due to the use of an indirect probit regression. The second concerns the time taken by PhD students to submit their thesis in a particular school. It illustrates a complex situation where three hierarchical levels of variation are modelled but with a simpler underlying probability distribution (log-Normal).

This paper presents the results of ground vibration measurements carried out in Hisarcik Boron open pit mine located on the west side of central Anatolia near Kütahya province in Turkey. Within the scope of this study to predict peak particle velocity (PPV) level for this site, ground vibration components were measured for 304 shots during bench blasting. In blasting operations, ANFO (blasting agent), gelatin dynamite (priming), and delay electric detonators (firing) were used as explosives. Parameters of scaled distance (charge quantity per delay and the distance between the source and the station) were recorded carefully and the ground vibration components were measured for all blast events using two different types of vibration monitors (one White Mini-Seis and one Instantel Minimate Plus Model). The absolute distances between shot points and monitor stations were determined using GPS. The equation of square root scaled distance extensively used in the literature was taken into consideration for the prediction of PPV. Then, the data pairs of scaled distance and particle velocity obtained from the 565 event records were analyzed statistically. At the end of statistical evaluation of the data pairs, an empirical relation which gives 50% prediction line with a reasonable correlation coefficient was established between PPV and scaled distance.

Background: Kisumu has shown a rising HIV prevalence over the past sentinel surveillance surveys, and most new infections are occurring among youth. We conducted a qualitative study to explore risk situations that can explain the high HIV prevalence among youth in Kisumu town, Kenya Methods: We conducted in-depth interviews with 150 adolescents aged 15 to 20, held 4 focus group discussions, and made 48 observations at places where youth spend their free time. Results: Porn video shows and local brew dens were identified as popular events where unprotected multipartner, concurrent, coerced and transactional sex occurs between adolescents. Video halls -rooms with a TV and VCRoften show pornography at night for a very small fee, and minors are allowed. Forced sex, gang rape and multiple concurrent relationships characterised the sexual encounters of youth, frequently facilitated by the abuse of alcohol, which is available for minors at low cost in local brew dens. For many sexually active girls, their vulnerability to STI/HIV infection is enhanced due to financial inequality, gender-related power difference and cultural norms. The desire for love and sexual pleasure also contributed to their multiple concurrent partnerships. A substantial number of girls and young women engaged in transactional sex, often with much older working partners. These partners had a stronger socio-economic position than young women, enabling them to use money/gifts as leverage for sex. Condom use was irregular during all types of sexual encounters. Conclusions: In Kisumu, local brew dens and porn video halls facilitate risky sexual encounters between youth. These places should be regulated and monitored by the government. Our study strongly points to female vulnerabilities and the role of men in perpetuating the local epidemic. Young men should be targeted in prevention activities, to change their attitudes related to power and control in relationships. Girls should be empowered how to negotiate safe sex, and their poverty should be addressed through income-generating activities.

The purposes of this study were to examine the percentage of female elite athletes and controls with disordered eating (DE) behavior and clinical eating disorders (EDs), to investigate what characterize the athletes with EDs, and to evaluate whether a proposed method of screening for EDs in elite athletes does not falsely classify sport-specific behaviors as indicators of EDs. All athletes representing the national teams at the junior or senior level, aged 13-39 years (n 5 938), and age-group matched, randomly selected population-based controls (n 5 900) were invited to participate. From the screening data, a random sample of athletes (n 5 186) and controls (n 5 145) were subjects for a clinical interview. More athletes in leanness sports (46.7%) had clinical EDs than athletes in non-leanness sports (19.8%) and controls (21.4%) (Po0.001). Variables predicting clinical EDs, and thus candidates for valid screening procedures, were menstrual dysfunction in leanness athletes, selfreported EDs in non-leanness athletes, and self-reported use of pathogenic weight control methods in controls. Hence, statistically based risk factors are not universally valid, but specifically related to athletes and non-athletes, respectively. EDs. Indeed, a recent controlled study identified a range of DE behaviors that predicted future EDs, like eating in secret, laxative abuse and a fear of losing control over eating.

Nowadays, access to reliable information has become an essential factor leading to success in business. In this regard, adequate security of information and systems that process it is critical to the operation of all organizations. Therefore organizations must understand and improve the current status of their information security in order to ensure business continuity and increase rate of return on investments. Since, information security has a very important role in supporting the activities of the organization and for this reason; it is needed to have a standard or benchmark which controls governance over information security. Hence, this paper discusses some of Information Security Management System (ISMS) standards in order to determine their strengths and challenges. Then, based on most appropriate standards in the field, a method is proposed to allow information technology-related or based enterprises to implement their ISMS. This method helps identifying critical assets and related threats and vulnerabilities, assessing assets risks and providing necessary risk treatment plans. The proposed method makes it possible and structured to establish information security management system in IT related large-scale enterprises.

Objective: The objectives of the study were to examine the prevalence of anorexia nervosa (AN), bulimia nervosa (BN), anorexia athletica (AA), and eating disorders not otherwise specified (ED-NOS) in both male and female Norwegian elite athletes and a representative sample from the general Norwegian population.

In the risk assessment process, financial auditors often rely on internal auditors when establishing the control risk level. Therefore, adequate internal audit function, as part of a solid corporate governance is a factor of lowering control risk, when assessing audit risks for Financial Investment Companies. The paper intends to approach issues related to internal audit as a relevant source of added value for listed companies and the main objectives related to internal audit engagements for Financial Investment Companies. The authors are trying to answer how internal audit contributes in an effective manner in the process of supervising corporate governance principles that Financial Investment Companies as listed companies, must comply with.

Clinical data are urgently needed to specify the risk and safety of drug use during pregnancy. For several reasons pregnant women are usually excluded from clinical studies. Therefore, observational data are the main source of knowledge, cohort studies as well as case-control studies. Disadvantages of cohort studies based on observational data have been repeatedly discussed. However, being involved in individual risk characterisation of pregnant women it is the experience of clinical teratologists that even reports on small cohorts should not be disregarded if no other data are available. The recently published "Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) Statement" underlines the value of observational data and provides a checklist regarding the most important inherent methodological problems. Our article describes how Teratology Information Services (TIS) document and evaluate their observations on pregnant women exposed to various drugs and discusses methodological problems and -considering the STROBE statement -how these could be addressed.

Objectives: The VOICE Asia study aimed to establish the mode of thromboprophylaxis in medical patients admitted to intensive care units (ICU), and to describe the epidemiology of patients at high-risk of venous thromboembolism (VTE) and of patients who were prescribed low molecular weight heparin (LMWH). Methods: This multinational, observational, cross-sectional study recruited medical patients admitted to ICU in whom a decision to give VTE prophylaxis had been taken. The treating physicians decided patient management. We recorded demographics, VTE risk factors, VTE risk assessment, thromboprophylaxis, and compliance to the American College of Chest Physicians (ACCP) guidelines. Results: The study enrolled 2969 patients from 113 centers in 5 Asian countries. The most common VTE risk factors were age >60 years (57.1%), prolonged immobility (50.6%), respiratory diseases (41.3%), and acute infectious disease (36.2%). There was a wide gap between physicians' assessment of 'very high' risk for VTE (8.4%) and Caprini 'very high' risk stratification (54.9%). 2919 (98.3%) patients received prophylaxis (22.9%-only mechanical, 31.2%-only pharmacological, 44.2%-both, mechanical and pharmacological and 1.7%-no prophylaxis). Early mobilization (44.3%) and LMWH (66.2%, mean duration of prophylaxis-8.6 days) were the most common mechanical and pharmacological prophylaxis, respectively. 80.6% of patients were given thromboprophylaxis as per the ACCP guidelines (and 4.7% per Japanese guidelines). Conclusions: There is substantial underestimation of VTE risk and non-adherence to guidelines for thromboprophylaxis in medical ICU patients in participating Asian countries. This emphasizes the need for increasing awareness about optimum VTE risk assessment and improved implementation of appropriate thromboprophylaxis in at-risk medical ICU patients.

Rosacea is a chronic disease with a profound impact on quality of life. Although there are a range of treatments for its many manifestations, some cases are difficult to treat. Sbidian et al. show in this double-blind, randomized, placebo-controlled trial that low-dose isotretinoin can be effective in treating difficult-to-treat and frequently relapsing papulopustular rosacea.

Background. Conventional pulmonary artery banding (CPAB) is associated with high morbidity and mortality. We studied the changes in outcome with the use of an adjustable pulmonary artery band (APAB). Methods. Between June 2001 and June 2006, 147 patients underwent PAB: 91 underwent CPAB and 56 underwent APAB. Results. The clinical profile of patients was similar in both groups. Inotropic drugs were used in 91 (100%) patients in the CPAB group and in 12 (21%) in the APAB group (p < 0.001). Early band related reoperation was required in 17 patients in the CPAB group compared with 2 patients in the APAB group (p ‫؍‬ 0.014). There were 21 (23%) early deaths in CPAB group compared with 1 (1.8%) in the APAB group (p < 0.001). There was no difference in the intensive care unit stay, hospital stay, and final band gradients in the two groups. On a mean follow-up of 22.8 ؎ 18.6 months (range, 4 to 72 months), there was PA distortion in 6 patients and band-migration in 4 patients in the CPAB group. These were not observed in the APAB group. Conclusions. Similar band gradients were achieved with the use of conventional or adjustable PAB. However, the use of this simple and inexpensive technique of APAB was associated with a significant reduction in the early band-related deaths, need for early multiple reoperations, and early adverse acute events, thus making it a safer alternative to CPAB, more so in unstable patients.

Using a broad suicide risk assessment (suicidal ideation, hopelessness, hostility) with 100 youth ages 17 to 19, this study examined the relationship between sexual orientation and youth suicide risk. Participants were compared across sexual orientation, as well as level of perceived external support, which may be a mitigating variable in suicide risk. The suicide risk demonstrated by sexual minorities in this study was no greater than that of their heterosexual peers. Youth who reported more external support demonstrated lower overall suicide risk and, specifically, lower levels of hostility, hopelessness, and suicidal ideation. The results indicated that suicide risk is not determined by demographic criteria alone, and may be influenced by psychosocial variables, such as support.

Patients with severe coronary artery disease with a clinical indication for revascularization but who are at high procedural risk because of patient comorbidities, complexity of coronary anatomy, and/or poor hemodynamics represent an understudied and potentially underserved patient population. Through advances in percutaneous interventional techniques and technologies and improvements in patient selection, current percutaneous coronary intervention may allow appropriate patients to benefit safely from revascularization procedures that might not have been offered in the past. The burgeoning interest in these procedures in some respects reflects an evolutionary step within the field of percutaneous coronary intervention. However, because of the clinical complexity of many of these patients and procedures, it is critical to develop dedicated specialists within interventional cardiology who are trained with the cognitive and technical skills to select these patients appropriately and to...
