Efficacy of a smoking cessation program for hospital patients.

BACKGROUND Hospitalization may be an opportune time to change smoking behavior because it requires smokers to abstain from tobacco at the same time that illness can motivate them to quit. A hospital-based intervention may promote smoking cessation after discharge. METHODS We tested the efficacy of a brief bedside smoking counseling program in a randomized controlled trial at Massachusetts General Hospital, Boston. The 650 adult smokers admitted to the medical and surgical services were randomly assigned to receive usual care or a hospital-based smoking intervention consisting of (1) a 15-minute bedside counseling session, (2) written self-help material, (3) a chart prompt reminding physicians to advise smoking cessation, and (4) up to 3 weekly counseling telephone calls after discharge. Smoking status was assessed 1 and 6 months after hospital discharge by self-report and validated at 6 months by measurement of saliva cotinine levels. RESULTS One month after discharge, more intervention than control patients were not smoking (28.9% vs 18.9%; P=.003). The effect persisted after multiple logistic regression analyses adjusted for baseline group differences, length of stay, postdischarge smoking treatment, and hospital readmission (adjusted odds ratio, 2.19; 95% confidence interval, 1.34-3.57). At 6 months, the intervention and control groups did not differ in smoking cessation rate by self-report (17.3% vs 14.0%; P=.26) or biochemical validation (8.1% vs 8.7%; P=.72), although the program appeared to be effective among the 167 patients who had not previously tried to quit smoking (15.3% vs 3.7%; P=.01). CONCLUSIONS A low-intensity, hospital-based smoking cessation program increased smoking cessation rates for 1 month after discharge but did not lead to long-term tobacco abstinence. A longer period of telephone contact after discharge might build on this initial success to produce permanent smoking cessation among hospitalized smokers.
Adaptability to Perturbation as a Predictor of Future Falls: A Preliminary Prospective Study

BackgroundFalls often result from failed responses to unexpected, externally applied perturbations. Whether performance-based, reaction-based, and/or adaptation-based assessment tools can predict future falls among community-dwelling older adults is unknown. PurposeThis preliminary prospective study examined the relationship between older adults' future fall risk and their reactive responses and adaptations to repeated slips, and their functional status. MethodsThirteen community-dwelling adults (>64 years) were exposed initially to a session of repeated slips. About 30 months later, self-reported falls experience data were collected for the preceding year from these participants. Slip outcome (fall, loss of balance, or recovery), slip score (weighted sum of slip outcomes), Timed Up and Go scores, and future fall incidence were recorded. ResultsFour participants who reported at least 1 fall had significantly higher slip scores than the rest. In contrast, neither failed recovery on the first slip nor a higher TUG score predicted greater odds of future falls. ConclusionCommunity-dwelling older adults' adaptability to externally imposed perturbations may reveal their future fall risk.
Social consequences of long term impairments and disabilities: conceptual approach and assessment of handicap

OBJECTIVES To present a conceptual model of disablement adapted from the WHO model and to conduct a pilot study with a measurement tool (LIFE-H) of the concepts of life habits and handicap situations. DESIGN Content validity and test-retest reliability study. SETTING General community. PARTICIPANTS A panel of 12 experts of rehabilitation for the process of content validity and 49 individuals with spinal cord disorders (adults and children) for the reliability study. OUTCOMES MEASURES a person's life habits (activities of daily living and social roles). RESULTS The LIFE-H questionnaire was designed to assess the handicap situations observed in daily life of individuals with disability. The experts concluded that the LIFE-H items covered most of a person's life habits (ADL and social roles) and that it could be used to determine the appearance of handicap situations. The LIFE-H total score showed a good level of reliability for the children and the adult samples (ICC = 0.73 and 0.74, respectively). Taken individually, a majority of life habit categories have shown a moderate to high reliability level (ICC > or = 0.50) while a few life habit categories such as the interpersonal relationship or nutrition showed a lower reliability level. CONCLUSION The development of LIFE-H allows fulfillment of the need to determine the disruptions in life habits of persons with disabilities.
Altering risky decision-making: Influence of impulsivity on the neuromodulation of prefrontal cortex

The prefrontal cortex (PFC) subserves complex cognitive abilities, including risky decision-making; the modulation of this brain area is shown to alter the way people take risks. Yet, neuromodulation of the PFC in relation to risk-taking behavior remains relatively less well-studied. Moreover, the psychological variables that influence such neuromodulation remain poorly understood. To address these issues, 16 participants took part in 3 experimental sessions on separate days. They received: (i) left anodal–right cathodal transcranial direct current stimulation (tDCS); (ii) left cathodal–right anodal stimulation; or (iii) sham stimulation while they completed two risk-taking tasks. They also measured on several cognitive–affective abilities and personality traits. It was revealed that left cathodal–right anodal stimulation led to significantly reduced risk-taking under a context of haste. The reduction of risk-taking (relative to sham) correlated with state and trait impulsivity, such that the effect was larger in more impulsive individuals. For these individuals, the tDCS effect size was considered to be large (generalized partial η2 > .17). The effect of prefrontal-neuromodulation in reducing risk-taking was influenced by baseline impulsivity, reflecting a state-dependent effect of neuromodulation on the PFC. The results of this study carry important insights into the use of neuromodulation to alter higher cognition.
Glucocorticoid‐induced fetal brain growth restriction is associated with p73 gene activation

Fetal exposure to excessive amounts of glucocorticoids (GCs) hampers proper brain development. The molecular mechanism(s) underlying these GCs effects are not well understood. We explored the impact of fetal exposure to maternal GCs on fetal brain expression of p63 and p73 transactivation (TA) and dominant negative (ΔN) gene variants that promote neural cell death (TA) and cell survival programs (ΔN). The fetoplacental enzyme 11β‐hydroxysteroid dehydrogenase 2, which shields fetuses from maternal glucocorticoids, was inhibited throughout pregnancy by daily injection of carbenoxolone to pregnant dams. The expression of p63 and p73 gene variants and proteins was monitored by real‐time rtPCR and Western blot in the brains of male and female fetuses. Carbenoxolone administration led to an overall enhanced level of corticosterone in the amniotic fluid of both male and female fetuses at late pregnancy. These enhanced corticosterone levels were associated with a significant reduction in fetal brain weights and a significant increase in TAp73 mRNA and p73 protein levels. However, the expression levels of TAp63 mRNA and p63 proteins were either suppressed or unaffected. The pro‐neural survival gene variant ΔNp73 was significantly reduced in female and enhanced in male fetal brains, whereas ΔNp63 was significantly reduced in the brains of both genders. These data suggest that the GCs‐induced negative impact on fetal brain development likely is due, at least in part, to their action of the pro‐neural cell death gene variant TAp73 and to the modulation of the pro‐survival ΔNp63 and ΔNp73 gene variants in a gender‐dependent fashion. © 2012 Wiley Periodicals, Inc.
The Current Management of Idiopathic Clubfoot Revisited: Results of a Survey of the POSNA Membership

Background: In 2001, the members of the Pediatric Orthopaedic Society of North America (POSNA) were surveyed regarding their approach to treating idiopathic clubfoot deformity. Since that time, several studies have advocated a change in the approach to treating this deformity, moving away from surgical release and toward less invasive methods. The purpose of this study was to assess the recent approach to treating clubfoot among the POSNA membership. Methods: A survey was emailed to all POSNA members to define their current treatment of idiopathic clubfoot deformity. Results: We received 323 responses. Ninety-three percent of participants were fellowship trained and were in practice for an average of 17.2 years. On an average, physicians reported each treating 23.5 new clubfoot patients during the year of survey. Nearly all (96.7%) of those surveyed stated that they use the Ponseti treatment method. The average time to initial correction was estimated at 7.1 weeks. Eighty-one percent of patients were estimated to require a tenotomy; 52.7% were performed under general anesthesia or conscious sedation, whereas 39.4% were done under local. Those surveyed estimated that 22% of clubfeet relapsed and 7% required a comprehensive release. Seventy-five percent of the respondents stated that their current treatment approach differed from how they were trained, and 82.7% were trained in the Ponseti method in the last few years. Conclusions: Our study provides convincing evidence that a large majority of pediatric orthopaedic surgeons now prefer the Ponseti method to treat idiopathic clubfoot and indicates that the move away from extensive release surgery occurred during the past decade. Level of Evidence: Not applicable.
Mental health problems among adults in tsunami-affected areas in southern Thailand.

CONTEXT On December 26, 2004, an undersea earthquake occurred off the northwestern coast of Sumatra, Indonesia. The tsunami that followed severely affected all 6 southwestern provinces of Thailand, where 5395 individuals died, 2991 were unaccounted for, and 8457 were injured. OBJECTIVE To assess the prevalence of symptoms of posttraumatic stress disorder (PTSD), anxiety, and depression among individuals residing in areas affected by the tsunami in southern Thailand as part of a public health emergency response and rapid assessment. DESIGN, SETTING, AND PARTICIPANTS A multistage, cluster, population-based mental health survey was conducted from February 15 to 22, 2005, of random samples of displaced (n = 371) and nondisplaced persons in Phang Nga province (n = 322) and nondisplaced persons in the provinces of Krabi and Phuket (n = 368). Data were collected using an interviewer-administered questionnaire on handheld computers. A surveillance follow-up survey of the displaced persons (n = 371) and nondisplaced persons (n = 322) in Phang Na was conducted in September 2005. MAIN OUTCOMES MEASURES Medical Outcomes Study-36 Short-Form Health Survey SF-36 to assess self-perceived general health, bodily pain, and social and emotional functioning; the Harvard Trauma Questionnaire to assess tsunami-specific traumatic events; and the Hopkins Checklist-25 to detect symptoms of anxiety and depression. RESULTS Participation rates for displaced and nondisplaced persons in the rapid assessment survey were 69% and 58%, respectively. Symptoms of PTSD were reported by 12% of displaced and 7% of nondisplaced persons in Phang Nga and 3% of nondisplaced persons in Krabi and Phuket. Anxiety symptoms were reported by 37% of displaced and 30% of nondisplaced persons in Phang Nga and 22% of nondisplaced persons in Krabi and Phuket. Symptoms of depression were reported by 30% of displaced and 21% of nondisplaced persons in Phang Nga and 10% of nondisplaced persons in Krabi and Phuket. In multivariate analysis, loss of livelihood was independently and significantly associated with symptoms of all 3 mental health outcomes (PTSD, anxiety, and depression). In the 9-month follow-up surveillance survey of 270 (73%) displaced and 250 (80%) nondisplaced participants in Phang Nga, prevalence rates of symptoms of PTSD, anxiety, and depression among displaced persons decreased to 7%, 24.8%, and 16.7%, respectively, and among nondisplaced persons, prevalence rates decreased to 2.3%, 25.9%, and 14.3%, respectively. CONCLUSIONS Among survivors of the tsunami in southern Thailand, elevated rates of symptoms of PTSD, anxiety, and depression were reported 8 weeks after the disaster, with higher rates for anxiety and depression than PTSD symptoms. Nine months after the disaster, the rates of those reporting these symptoms decreased but were still elevated. This information is important for directing, strengthening, and evaluating posttsunami mental health needs and interventions.
Susceptibility of Larval Aedes aegypti and Aedes albopictus (Diptera: Culicidae) to Dengue Virus

ABSTRACT Mosquitoes vertically transmit many arthropod borne viruses, and as a consequence arboviruses are often present within the larval environment. We tested the hypothesis that Aedes aegypti (L.) and Aedes albopictus (Skuse) larvae were susceptible to dengue virus through two infection methods: exposure to dengue in the larval growth environment via viral supernatant, and exposure to infected tissue culture along with viral supernatant. In addition to investigating for the first time the susceptibility of larval Ae. albopictus to dengue virus, we analyzed the infection rate and viral titer of infected pools of Ae. aegypti when exposed to multiple serotypes of dengue. We found that both Ae. aegypti and Ae. albopictus larvae were susceptible to the three dengue virus serotypes to which they were exposed regardless of the exposure method and that there were significant differences between the serotypes in infection titer and infection rate. The finding that larval Ae. aegypti and Ae. albopictus are susceptible to dengue indicates that dengue might be able to spread among larvae within the larval habitat potentially contributing to the persistence of dengue in the environment.
A critical assessment of edaravone acute ischemic stroke efficacy trials: is edaravone an effective neuroprotective therapy?

Importance of the field: Edaravone (Radicut®) is a free radical scavenger marketed in Japan by Mitsubishi Tanabe Pharma Corp. to treat acute ischemic stroke (AIS) patients presenting within 24 h of the attack. Injectable edaravone ampoules (30 mg b.i.d., i.v., 14 days) were first approved on 23 May 2001. On 19 January 2010, as a new innovation, the Radicut BAG (Intravenous BAG) was approved by the Japanese Ministry of Health and Welfare. Efficacy of edaravone ranges from large significant clinical improvements to only modest improvements in clinical function measured using standard stroke scales when administered 6 – 72 h following an ischemic stroke. With almost 17 years of edaravone clinical experience, a few adverse events – including acute renal failure – have been noted. What the reader will gain: This is the only article to date to critically review available clinical efficacy and toxicology data published in the literature to ascertain whether edaravone should be further pursued as a candidate for development worldwide. Areas covered in this review: This review covers clinical studies carried out over the period 1993 – 2008. Take home message: Edaravone may be a useful neuroprotective agent to treat the > 15 million victims worldwide who are devastated by stroke annually. Additional clinical studies are necessary to verify the efficacy of edaravone.
Information Technology and Quantitative Management ( ITQM 2013 ) Analysis on Overlapped and Non-overlapped Data

Similarity measure design on non-overlapped data was carried out, and compared with the case of overlapped data. By the application result, it was proved that the conventional similarity measure was not proper to calculate the similarity measure of the non-overlapped case. To solve the similarity measure design problem, neighbor data distance was considered to design the similarity measure of non-overlapped data. Hence different approach to design similarity measure was proposed and proved with consideration of neighbor information. With the example of artificial data, similarity measure calculation was carried out. Similarity measure extension to intuitionistic fuzzy sets(IFSs) containing uncertainty named hesitance was also followed
What leads to different mediators of alkalosis-induced vasodilation in isolated and in situ pulmonary vessels?

We previously found that nitric oxide synthase (NOS) inhibition fully blocked alkalosis-induced relaxation of piglet pulmonary artery and vein rings. In contrast, NOS inhibition alone had no effect on alkalosis-induced pulmonary vasodilation in isolated piglet lungs. This study sought to identify factors contributing to the discordance between isolated and in situ pulmonary vessels. The roles of pressor stimulus (hypoxia vs. the thromboxane mimetic U-46619), perfusate composition (blood vs. physiological salt solution), and flow were assessed. Effects of NOS inhibition on alkalosis-induced dilation were also directly compared in 150-350-microm-diameter cannulated arteries and 150-900-microm-diameter, angiographically visualized, in situ arteries. Finally, effects of NOS inhibition on alkalosis-induced vasodilation were measured in intact piglets. NOS inhibition with N(omega)-nitro-L-arginine fully abolished alkalosis-induced vasodilation in all cannulated arteries but failed to alter alkalosis-induced vasodilation in intact lungs. The results indicate that investigation of other factors, such as perivascular tissue (e.g., adventitia and parenchyma) and remote signaling pathways, will need to be carried out to reconcile this discordance between isolated and in situ arteries.
Comparison of the responses to moving texture patterns of simple and complex cells in the cat's area 17.

1. Whether complex (C) cells are the only truly texture-sensitive units in the cat's primary visual cortex remains controversial. In view of the strong physiological significance of having putatively only one class of cells sensitive to visual noise in the striate cortex, we reinvestigated this issue. Sensitivities of simple (S) and C cells to noise were quantitatively studied and compared in order to clearly document the response properties of cells in the striate cortex to visual noise and to establish whether one can unequivocally segregate S from C cells on the basis of those specific properties. 2. Receptive fields were stimulated with all relevant stimuli, i.e., drifting sine-wave gratings, electronically generated noise pattern of 256 x 256 elements (ratio 1:1 of dark and light elements), and flashing and moving bars (both bright and dark). 3. A total of 60 S cells out of 85 (70.6%) and 90 C cells out of 101 (81.8%) responded to the motion of visual noise. Responses of most C cells were sustained, i.e., their discharge rate was maintained at a constant level throughout presentation of the stimulus. On the other hand, responses of the majority of S cells were characterized by several bursts of discharges. On average, optimal firing rates were greater for gratings than for noise. 4. For practically all cells, responses to noise varied as a function of direction of motion. The mean direction bandwidths were, respectively, 43 +/- 24 degrees and 48 +/- 23 degrees (mean +/- SD) for S and C cells. In both groups, neurons were more broadly tuned for the direction of noise than that of gratings (t-test, P < 0.001). We rarely observed bimodal tuning curves for noise, with each peak lying on either side of the orientation curve. These results could be expected if one considers texture stimuli not in the space domain (as dot patterns) but in the frequency domain, i.e., patterns containing all spatial frequencies and orientations. 5. In general, the direction indexes of S and C cells were similar whether they were stimulated by drifting noise or gratings. S cells had a slight tendency to be more direction selective for noise than for gratings. 6. For all S and C cells tested, responses to noise varied as a function of drift velocity. The mean optimal velocity was 12.9 and 10.2 degrees/s for S and C cells, respectively (t-test, P > 0.05). Most cells were band-pass with mean bandwidths of 2.2 and 2.7 octaves for S and C cells, respectively. (ABSTRACT TRUNCATED AT 400 WORDS)
Migraine in Metabolic Syndrome

Objectives:Recent studies suggest that insulin resistance is more common in patients with migraine. Insulin resistance underlies the pathogenesis of obesity, diabetes, and hypertension that are components of metabolic syndrome. As migraine is associated with an increased risk of vascular disorders, such as stroke, and migraine patients have higher diastolic blood pressure than healthy individuals, we aimed to investigate the 1-year prevalence of migraine in metabolic syndrome. Methods:Two hundred ten patients with metabolic syndrome were enrolled in the study. Migraine was diagnosed according to International Classification of Headache Disorders-II criteria. Results:Migraine prevalence was estimated as 11.9% in men and 22.5% in women with metabolic syndrome. Of the metabolic syndrome components, diabetes, increased waist circumference, and body mass index were significantly more frequent in patients with migraine in contrast to those without migraine (P <0.05). Hypertension and dyslipidemia frequencies showed no difference between 2 groups. Conclusions:Our results demonstrate that migraine prevalence in metabolic syndrome was higher than in the general population.
Rate-adaptive admission control for bandwidth assurance in multirate wireless mesh networks

Admission control (AC) is an effective mechanism for providing bandwidth assurance in wireless mesh networks. Early AC schemes over multirate WMNs typically use a pre-chosen rate or a MAC-layer adapted rate for each link, denying data sessions that could have been admitted should a better multirate AC be available. Taking full advantage of multirate WMNs, we present a rate-adaptive admission control protocol (RaAC) for IEEE 802.11-based WMNs. RaAC consists of three major components: (1) a rate adaption algorithm to meet the bandwidth requirement of the data session and satisfy the channel condition of the PHY layer; (2) a new path-selection metric to balance between hop counts, bandwidth, rates, and other network parameters; and (3) a routing-coupled, distributed, rate-adaptive admission control algorithm to admit data sessions with bandwidth assurance. Through simulations, we show that RaAC is efficient and effective in meeting bandwidth requirements.
The hereditary palmoplantar keratoses: an updated review and classification

The palmoplantar keratoses (PPKs) comprise a heterogeneous group of disorders of keratinization, which can be subdivided into hereditary and acquired forms. Many authors have attempted to classify the hereditary forms,1–5 and most classifications have been based on the morphology, distribution, associated symptoms and mode of inheritance. Subsequently, many new forms have been recognized, and what were previously considered to be distinct types have been shown to be variants of a single type, both of which limit the usefulness of previous classifications. Hence, we propose a new, updated classification, which enables accurate diagnosis of these disorders.
