    Full Text Available Abstract Background Chlorine dioxide (CD gas has a potent antimicrobial activity at extremely low concentration and may serve as a new tool for infection control occupationally as well as publicly. However, it remains unknown whether the chronic exposure of CD gas concentration effective against microbes is safe. Therefore, long-term, low concentration CD gas inhalation toxicity was studied in rats as a six-month continuous whole-body exposure followed by a two-week recovery period, so as to prove that the CD gas exposed up to 0.1 ppm (volume ratio is judged as safe on the basis of a battery of toxicological examinations. Methods CD gas at 0.05 ppm or 0.1 ppm for 24 hours/day and 7 days/week was exposed to rats for 6 months under an unrestrained condition with free access to chow and water in a chamber so as to simulate the ordinary lifestyle in human. The control animals were exposed to air only. During the study period, the body weight as well as the food and water consumptions were recorded. After the 6-month exposure and the 2-week recovery period, animals were sacrificed and a battery of toxicological examinations, including biochemistry, hematology, necropsy, organ weights and histopathology, were performed. Results Well regulated levels of CD gas were exposed throughout the chamber over the entire study period. No CD gas-related toxicity sign was observed during the whole study period. No significant difference was observed in body weight gain, food and water consumptions, and relative organ weight. In biochemistry and hematology examinations, changes did not appear to be related to CD gas toxicity. In necropsy and histopathology, no CD gas-related toxicity was observed even in expected target respiratory organs. Conclusions CD gas up to 0.1 ppm, exceeding the level effective against microbes, exposed to whole body in rats continuously for six months was not toxic, under a condition simulating the conventional lifestyle in human.

    Aflatoxins (AFTs) are a group of closely related toxins that are produced by different fungus species. Food and feed contamination with AFT is a worldwide health-related problem. As a result of fungal attack, the food and feed resulted in a principal socioeconomic loss and toxins produced in feed and food items harm the humans and animals in different ways. The anti-aflatoxigenic effect Psidium guajava, Ficus benghalensis, Gardenia radicans, Punica granatum and Ziziphus jujuba leaves were evaluated against aflatoxins (AFTs), produced by Aspergillus flavus in layer feed during storage. Among the investigated medicinal plant leaves, P. granatum showed highly promising anti-aflatoxigenic activity and completely inhibited the AFTs (B1 and B2) production over storage period without compromising the nutritive quality of feed (ash, protein, fat, fiber, Fe, Ca, P and K contents). Leaves of F. benghalensis and Z. jujuba were also effective however, higher concentration (15%) inhibited the AFTs production up to 99% and also maintained nutritive quality of feed. G. radicans was found least effective in controlling the AFTs production. Results revealed that all plant leaves were effective in controlling AFTs production in layer feed over the storage period of six months and these plants are potential candidate to replace the fungicides used to protect feed and other agricultural commodities from AFTs production during storage.

    Full Text Available Background: Performance monitoring might have an adverse influence on call center agents’ well-being. We investigate how performance, over a six-month period, is related to agents’ perceptions of their learning climate, character strengths, well-being (subjective and psychological, and physical activity.Method: Agents (N = 135 self-reported perception of the learning climate (Learning Climate Questionnaire, character strengths (Values In Action Inventory Short Version, well-being (Positive Affect, Negative Affect Schedule, Satisfaction With Life Scale, Psychological Well-Being Scales Short Version, and how often/intensively they engaged in physical activity. Performance, time on the phone, was monitored for six consecutive months by the same system handling the calls. Results: Performance was positively related to having opportunities to develop, the character strengths clusters of Wisdom and Knowledge (e.g., curiosity for learning, perspective and Temperance (e.g., having self-control, being prudent, humble, and modest, and exercise frequency. Performance was negatively related to the sense of autonomy and responsibility, contentedness, the character strengths clusters of Humanity and Love (e.g., helping others, cooperation and Justice (e.g., affiliation, fairness, leadership, positive affect, life satisfaction and exercise Intensity.Conclusion: Call centers may need to create opportunities to develop to increase agents’ performance and focus on individual differences in the recruitment and selection of agents to prevent future shortcomings or worker dissatisfaction. Nevertheless, performance measurement in call centers may need to include other aspects that are more attuned with different character strengths. After all, allowing individuals to put their strengths at work should empower the individual and at the end the organization itself. Finally, physical activity enhancement programs might offer considerable positive work outcomes.

  4. Is a home based video teleconcltation setup cost effective for lowering HBA1C for patients with type-2 diabetes over a six-month period?

    1981-11-01

    The statistics set forth for the period covered in this report are based on data gathered from records available to the public. The county records of mining claim locations, reports of state and federal land offices, and commercial reporting services furnish the data for this report. Accordingly, if any fee land has been acquired in a private transaction not entered into a public record or report, that land transaction will not be accounted for in this report. Manpower is not available to survey, acquire, and evaluate data from each available source in each reporting period. Therefore, in any given report, the figures quoted for one or more land categories in a given state may be identical to the figures shown in earlier reports even though some changes probably have occurred. Such changes will be shown on subsequent reports. The figures used for acreage controlled at the beginning of the calender year are those published for that date in Statistical Data of the Uranium Industry GJO-100(81) published and distributed by the Grand Junction Area Office of the Department of Energy

    2016-06-01

    The purpose of this study was to investigate the prevalence of antiseptic-resistance (QAC) genes in staphylococci colonizing periorbital tissues and accessories of orthokeratology (ortho-k) lens wearers over a 6-month period and determine the effect of their presence on minimum inhibitory (MIC) and bactericidal concentrations (MBC) of disinfectants and log reduction of multipurpose contact lens solutions (MPS). Staphylococci were isolated from periorbital tissues and accessories of patients before commencing ortho-k therapy and at two subsequent visits. Presence of QAC genes in 116 S. aureus and 67 CNS isolates was determined by PCR and association with period of ortho-k use determined. MICs and MBCs of staphylococci gene-positive were compared with gene-negative strains and the effectiveness of four MPS for rigid contact lenses investigated. S. aureus carriage rates in the conjunctiva decreased significantly from 41.2 % (baseline) to 11.8 % (3-months), and 13.3 % (6-months) (p trend 0.03), while CNS increased from 58.8 %(baseline) to 94.1 % (3-months), and 93.3 % (6-months) (p trend 0.02). Prevalence of qacA/B increased considerably over time (S. aureus: 4.4 % to 15.4 %, CNS: 6.7 % to 25 %), but frequency of smr was relatively stable. Only five CNS isolates harboured qacH. MICs and MBCs of gene-positive isolates were significantly increased and three MPS did not achieve a 3-log reduction of many QAC-positive strains. Ortho-k lens wear contributed to changes of staphylococcal carriage rates in the conjunctival sac. Use of MPS containing quaternary ammonium compounds may select for the carriage of organisms harbouring QAC genes, as the low concentration of disinfecting agents is not adequate for killing gene-positive strains.

    1988-01-01

    This report outlines the activities of Northern Territory Government authorities (Department of Mines and Energy (DME), Conservation Commission and Department of Health and Community Services (DHCS) in meeting their responsibilities for surveillance of environmental monitoring in the Alligator Rivers Region for the period 1 April to 30 September 1988. The responsibility for DME activities derives principally from the Mining Act, the Mines Safety Control Act, the Control of Waters Act and the Uranium Mining (Environment Control) Act, referred to in this report as the UMEC Act. The Land Conservation Unit (LCU) of the Conservation Commission and the Occupational and Environmental Health Branch of DHCS, furnish technical advice to the Alligator Rivers Region Unit of DME, which then collates the data for Authorizations, approvals and compliance reports. The responsibilities of the Conservation Commission derive from the Soil Conservation and Land Utilization Act. DHCS activities derive from, in addition to the relevant Mines Acts, the Silicosis and Tuberculosis (Mine Workers and Prospectors) Act, Radiation (Safety Control) Act and the Public Health Act

    Full Text Available Objective. To assess the efficacy and tolerability of the association sibutramine (10–20 mg/day and orlistat (120 mg 2-3 times a day in the treatment of obesity in a six-month open trial. Methods. 446 overweight and obese patients who sought treatment for obesity in a private clinic were assessed every 2 weeks during a period of 3 and 6 months. Results. After 3 months, the mean weight loss was 10.5 kg (−9.8% of the initial weight, =263, and after 6 months, the mean weight loss was 13.9 kg (−12.8% of the initial weight, =97. The tolerability of such association was quite acceptable and coherent with the action mechanism of each component. Conclusions. The association of orlistat and sibutramine is quite efficient and it seems to promote a higher rate of weight loss than that reported in clinical studies performed with each drug separately.

    In this study, the authors examined changes in the soil nutrient levels in marsh systems after fire. These studies were conducted in conjunction with studies of particulates and gases generated from biomass combustion and flux measures of methane and nitric oxide before and after the fire. Here data are presented through six months postfire, past the time during which flux measurements were made. These data indicate that changes in soil properties occur at different times after the fire and persist for different intervals, indicating the need for long-term postfire observations

  14. Six month suspension of Tsuruga nuclear power plant ordered

    International Nuclear Information System (INIS)

    1981-01-01

    This report first describes on brief review of the troubles at Tsuruga Nuclear Power Station. All these accidents or troubles were settled within the Tsuruga Nuclear Power Station, and none was reported either to the Agency of Natural Resources and Energy (ANRE) of Ministry of International Trade and Industry, which is responsible for the supervision of nuclear power plants, or even to the head of Japan Atomic Power Co. (JAPCO). JAPCO criticized itself for the failure to recognize the importance of proper communication. It has been decided that Mr. Suzuki, President of JAPCO, will be succeeded by Mr. Okabe, Managing Director of Tokyo Electric Power Co. It was ordered that the operation of the Tsuruga Nuclear Power Station should be suspended for six months, in accordance with the Reactor Regulation Law, because of the violation of the safety regulations. The final report of ANRE said that ANRE has determined to make maximum efforts to ensure the safety of nuclear power plants, in order to prevent the recurrence of such an accident, and to restore public confidence in nuclear power plants. Nuclear Safety Commission declared that there would be no present or future effect of the radiation leakage on the local people. Local people's organization is lodging complaint against JAPCO. It is expected that the talks between the Ministries of Home Affairs and International Trade and Industry will center on the strengthening of contacts between nuclear power plants and local self-government bodies.

    Experience using low-dose radioiodine given six-monthly instead of yearly in hyperthyroid patients with Graves' disease is reported. One hundred and thirty-five patients have been treated over a three-year period with 74 MBq (2 mCi) doses of 131 I. |Thirty-eight|percent| were controlled with a single dose. Those patients requiring more than one dose were treated with a further 74 MBq (2 mCi) 131 I at six-monthly intervals until euthyroid. Using this approach, 46% were euthyroid one year after starting treatment, and 75% were euthyroid at two years. The incidence of hypothyroidism following treatment was 2.2% at one year, with a yearly incidence thereafter of 4-6%. Six-monthly scheduling of low-dose radioiodine in Graves' disease can reduce the time taken to become euthyroid, compared with conventional yearly low-dose treatments. Further follow up is required to confirm the present low incidence of hypothyroidism following treatment. (author)

    2011-02-01

    Full Text Available Abstract Background Breastfeeding is accepted as the natural form of infant feeding. For mothers to be able to breastfeed exclusively to the recommended six months, it is important to understand the factors that influence exclusive breastfeeding. The aim of the study was to identify factors associated with exclusive breastfeeding in Peninsular Malaysia. Methods This was a cross-sectional study involving 682 mother-infant pairs with infants up to six months attending maternal and child health section of the government health clinics in Klang, Malaysia. Data were collected by face-to-face interviews using a pre-tested structured questionnaire over 4 months in 2006. Data on breastfeeding were based on practice in the previous one month period. Logistic regression was used to assess the independent association between the independent variables and exclusive breastfeeding adjusting for infant age. Results The prevalence of exclusive breastfeeding among mothers with infants aged between one and six months was 43.1% (95% CI: 39.4, 46.8. In the multivariate model exclusive breastfeeding was positively associated with rural residence, Malay mothers, non-working and non-smoking mothers, multiparous mothers, term infants, mothers with husbands who support breastfeeding and mothers who practice bed-sharing. Conclusions Interventions that seek to increase exclusive breastfeeding should focus on women who are at risk of early discontinuation of breastfeeding.

    Aims of the study were to describe behavioral health treatment utilization patterns of community-dwelling older adults with depressive symptoms over a six-month period and to identify factors associated with treatment use, guided by a theoretical model emphasizing the dynamic nature of treatment use patterns over time and social context. A total of 144 participants ≥65 years old with depressive symptoms completed an in-person baseline interview and six monthly telephone follow-up interviews. Outcomes at each follow-up included the use of antidepressants or counseling. Covariates included personal and social context variables. Approximately half of the participants (N=70, 48%) received no formal treatment (antidepressant prescription or counseling). Treatment use or nonuse did not change for most participants. More participants with severe symptoms received antidepressants (25%-37%) than did those with milder symptoms (10%-14%), although more participants in the latter group started (milder, 62%,versus severe, 49%) and stopped (milder, 77%, versus severe, 26%) antidepressant treatment at least once. Fewer individuals received counseling overall, with no clear patterns by symptom severity. In multivariate longitudinal analyses, treatment use at follow-up was independently associated with younger age, current major depressive episode, baseline use of antidepressant, intention to begin a new treatment at baseline, and receipt of advice to seek treatment. Over a six-month period, most older adults with depressive symptoms in this study continued their use or nonuse of mental health treatment. Demographic, need, attitudinal, and social variables were related to treatment use over time. Addressing intentions and providing advice may facilitate treatment seeking.

    Full Text Available Abstract Background Effective communication between clinicians is essential for safe, efficient healthcare. We undertook a study to determine the longer-term effectiveness of an education session employing a structured method to teach referral-making skills to medical students. Methods All final year medical students received a forty-five minute education intervention consisting: discussion of effective telephone referrals; video viewing and critique; explanation, demonstration and practice using ISBAR; provision of a memory aid for use in their clinical work. Audio recordings were taken during a subsequent standardised simulation scenario and blindly assessed using a validated scoring system. Recordings were taken immediately before (control, several hours after (intervention, and at approximately six months after the education. Retention of the acronym and self-reports of transfer to the clinical environment were measured with a questionnaire at eight months. Results Referral clarity at six months was significantly improved from pre-intervention, and referral content showed a trend towards improvement. Both measures were lower than the immediate post-education test. The ISBAR acronym was remembered by 59.4% (n = 95/160 and used by the vast majority of the respondents who had made a clinical telephone referral (n = 135/143; 94.4%. Conclusions A brief education session improved telephone communication in a simulated environment above baseline for over six months, achieved functional retention of the acronym over a seven to eight month period and resulted in self reports of transfer of the learning into practice.

    Full Text Available Abstract Background The rise in disability due to back pain has been exponential with escalating medical and societal costs. The relative contribution of individual prognostic indicators to the pattern of recovery remains unclear. The objective of this study was to determine the prognostic value of demographic, psychosocial, employment and clinical factors on outcome in patients with low back pain Methods A prospective cohort study with six-month follow-up was undertaken at a multidisciplinary back pain clinic in central London employing physiotherapists, osteopaths, clinical psychologists and physicians, receiving referrals from 123 general practitioners. Over a twelve-month period, 593 consecutive patients referred from general practice with simple low back pain were recruited. A baseline questionnaire was developed to elicit information on potential prognostic variables. The primary outcome measures were change in 24-item Roland Morris disability questionnaire score at six months as a measure of low back related functional disability and the physical functioning scale of the SF-36, adjusted for baseline scores. Results Roland Morris scores improved by 3.8 index points (95% confidence interval 3.23 to 4.32 at six months and SF-36 physical functioning score by 10.7 points (95% confidence interval 8.36 to 12.95. Ten factors were linked to outcome yet in a multiple regression model only two remained predictive. Those with episodic rather than continuous pain were more likely to have recovered at six months (odds ratio 2.64 confidence interval 1.25 to 5.60, while those that classified themselves as non-white were less likely to have recovered (0.41 confidence interval 0.18 to 0.96. Conclusions Analysis controlling for confounding variables, demonstrated that participants showed greater improvement if their episodes of pain during the previous year were short-lived while those with Middle Eastern, North African and Chinese ethnicity demonstrated

  1. Canadian petroleum industry: 1991 monitoring report. First six months

    International Nuclear Information System (INIS)

    1991-01-01

    This report describes the financial performance of the oil and gas industry in Canada during the first 6 months of 1991. The report is based on data from 145 companies accounting for ca 90% of total revenues of the petroleum industry. The report lists noteworthy happenings in the industry, gives highlights of the 6-month period, then details financial performance, sources and uses of funds, comparative performance with other industries, international flows of funds compared to the previous year, capital structures compared to the previous year, and gives income tax-related data for the current and previous years. New chapters on employment levels within the upstream part of the industry for the period 1985 to 1990 and on selected financial results of the petroleum industry for the third quarter and the first nine months of 1991 have been included. Compared to the first 6 months of 1990, industry cash flow dropped 15% to $3.4 billion and net income fell $1.1 billion from a profit of $815 million to a loss of $260 million. Both upstream and downstream segments of the industry recorded lower net income and cash flow. Higher operating costs in the upstream segment and significantly lower downstream margins were major causes of the poor financial performance of the petroleum industry. As a result, the rate of return on average shareholder's equity was an annualized negative 1.2%. The industry increased overall capital expenditures by 19% to $4.6 billion, largely on the strength of commitments to major projects such as the Caroline gas field development, Hibernia, Cohasset/Panuke and the Bi-Provincial Upgrader. This increase, together with the drop in cash flow, resulted in a reinvestment rate of 134%. 24 figs., 66 tabs

  4. Reasons for Stopping Exclusive Breastfeeding Between Three and Six Months: A Qualitative Study.

    Science.gov (United States)

    Alianmoghaddam, Narges; Phibbs, Suzanne; Benn, Cheryl

    Scant published qualitative literature exists focusing on why exclusive breastfeeding rates decline between three and six months. This study aims to develop an understanding of why exclusive breastfeeding tails off so dramatically between three and six months after birth in New Zealand. A generic qualitative methodology was employed in this study and social constructionism selected as the main epistemological framework underpinning the research. This study was carried out between September 2013 and July 2014, involving face-to-face interviews with 30 women who were characterised as highly motivated to complete six months exclusive breastfeeding prior to the birth of their child. In order to gain an in-depth understanding of the research material, thematic analysis of the interview transcripts was completed using manual coding techniques. After thematic analysis of the data four key themes were identified: 1) The good employee/good mother dilemma. 2) Breastfeeding is lovely, but six months exclusively is demanding. 3) Exclusive breastfeeding recommendations should be individualised. 4) Introducing solids early as a cultural practice. Most studies have linked barriers to six months exclusive breastfeeding to difficulties within the mother-infant dyad, as well as negative maternal socioeconomic and socio-demographic characteristics. However, this study has shown that the maintenance of six months exclusive breastfeeding is also challenging for this group of mothers who were socially advantaged, well-educated and highly motivated to breastfeed their babies exclusively for six months.

    This publication provides a large number of indicators and graphs related to electricity produced in metropolitan France from renewable sources, as well as the main indicators for some European countries (for which network managers are members of the ENTSO-E). It addresses the status of the wind energy production stock (connected stock in June 2014, regional distribution, and production technologies), the growth perspectives, and the role of wind energy production in the supply-demand balance (production and load factor, regional distribution of production and load factor, share in consumption coverage, regional discrepancies, wind energy flow management in the electric system), and the main figures of the wind energy sector in Europe. Using the same kind of presentation and the same issues, the second part presents and comments data related to energy production in France: photovoltaic stock (connected stock in June 2014, regional distribution, installation distribution in terms of power range, production technologies), growth perspectives, and role of photovoltaic energy production in the supply-demand balance (production and load factor, production and load factor regional distribution, role in consumption coverage, production characteristics, photovoltaic production flow management), and main figures for the photovoltaic sector in Europe. The third part addresses hydraulic energy: key data and institutional context, hydraulic production stock (station types, regional distribution, distribution in terms of power range), hydraulic production share in the supply-demand balance, consumption coverage rate by production, key figures for the hydraulic sector in Europe. The fourth part comments the elaboration and implementation of Regional Schemes of Connection to the renewable energy network (S3REnR) which ensure conditions of connection to the electric grid of all renewable energies

    Gastro-oesophageal reflux (GOR) is common in infants, and feed thickeners are often used to manage it in infants as they are simple to use and perceived to be harmless. However, conflicting evidence exists to support the use of feed thickeners. To evaluate the use of feed thickeners in infants up to six months of age with GOR in terms of reduction in a) signs and symptoms of GOR, b) reflux episodes on pH probe monitoring or intraluminal impedance or a combination of both, or c) histological evidence of oesophagitis. We used the standard search strategy of the Cochrane Neonatal Review Group to search the Cochrane Central Register of Controlled Trials (CENTRAL 2016, Issue 2), MEDLINE via PubMed (1966 to 22 November 2016), Embase (1980 to 22 November 2016), and CINAHL (1982 to 22 November 2016). We also searched clinical trials databases, conference proceedings, and the reference lists of retrieved articles for randomised controlled trials. We included randomised controlled trials if they examined the effects of feed thickeners as compared to unthickened feeds (no treatment or placebo) in treating GOR in term infants up to six months of age or six months of corrected gestational age for those born preterm. Two review authors independently identified eligible studies from the literature search. Two review authors independently performed data extraction and quality assessments of the eligible studies. Differences in opinion were resolved by discussion with a third review author, and consensus was reached among all three review authors. We used the GRADE approach to assess the quality of the evidence. Eight trials recruiting a total of 637 infants met the inclusion criteria for the systematic review. The infants included in the review were mainly formula-fed term infants. The trials were of variable methodological quality. Formula-fed term infants with GOR on feed thickeners had nearly two fewer episodes of regurgitation per day (mean difference -1.97 episodes per day

    Specific anti-human leukocyte antigen antibodies (HLA) in the post-transplant period may be present with acute rejection episodes (ARE), and high soluble CD30 (sCD30) serum levels may be a risk factor for ARE and graft loss. HLA cross-matching, panel reactive antibodies (PRA), and sCD30 levels were determined prior to transplantation in 72 patients. Soluble CD30 levels and PRA were re-assessed at day 7, 14, 21, and 28, and monthly up to the sixth.   Twenty-four subjects had a positive PRA and 17 experienced ARE. Nine of 17 ARE subjects demonstrated positive PRA and 16 had HLA mismatches. Positive PRA was more frequent in ARE subjects (p = 0.03). Eight subjects with ARE had donor-specific antibodies (DSA) in serum samples pre-transplantation, two subjects developed DSA. Three subjects without ARE had positive PRA only in post-transplantation samples. Soluble CD30 levels were higher in pre-transplant samples and ARE subjects than non-ARE subjects (p = 0.03). Post-transplant sCD30 levels were elevated in subjects who experienced rejection and were significantly higher at seven d (p = 0.0004) and six months (p = 0.03). Higher sCD30 levels following transplant were associated with ARE. Elevated sCD30 levels may represent a risk factor for acute rejection. © 2009 John Wiley & Sons A/S.

    Previous research has found an inverse cross-sectional relationship between an individual's access to social capital (defined as resources embedded within social networks) and depression, but this relationship has not been rigorously tested in prospective research. This is the first longitudinal study to evaluate the effect of social capital on the course of depression and subjective quality of life in a clinical population. This was a six-month prospective cohort study of people with depression in primary care achieving a follow-up rate of 91.3% (n=158). Depression was measured with the HAD-D and social capital using the Resource Generator-UK. Potential confounding variables including socio-demographics, socio-economic status, depression history, social support, life events and attachment style were also measured. Social capital had no independent effect on the course of depression, though an interaction of access to social capital and attachment style was significantly related to change in quality of life alongside multiple covariates. The study used a small sample; a short follow-up period; no measure of ecological social capital; no genetic components; and only two time points. Emotional support is important for the alleviation of depression. Additionally, people with depression may require a secure attachment style to derive the full benefit of their social capital.

    Diet influences the health of the foetus and the woman during pregnancy and later in life. It is therefore important to investigate pregnant women's food habits. The aim of this study was to describe women's food habits during pregnancy and up to six months post-partum. A Food Frequency Questionnaire (VIP-FFQ) was distributed to 163 pregnant women on five occasions during and after pregnancy. Data were analysed using Friedman's ANOVA and a Bonferroni post-hoc test. Food habits in relation to the National Food Agency's (NFA) food index. The pregnant women's diets were inadequate according to the NFA food index. A tendency towards an even poorer diet after delivery was identified, something which was related to an increased intake of discretionary food, e.g. sweets, cakes, cookies, crisps, ice cream, and decreased intake of fruit and vegetable. The alcohol consumption was low throughout. The food habits during pregnancy were inadequate compared to recommendations and these habits became unhealthier after delivery. These suggest that dietary counselling needs to be more effective and continued into the lactating period. An increased focus should be given to healthy eating from the life course perspective, not just focus on effects on the foetus and pregnancy outcomes. Copyright © 2016 Elsevier B.V.

  10. Six-Month Market Exclusivity Extensions To Promote Research Offer Substantial Returns For Many Drug Makers.

    To incentivize pharmaceutical manufacturers to invest in areas of unmet medical need, policy makers frequently propose extending the market exclusivity period of desired drugs. Some such proposals are modeled after the pediatric exclusivity patent extension program, which since 1997 has provided six additional months of market exclusivity for drugs studied in children. The most recent proposal would encourage rare disease research by providing six months of extended exclusivity for any existing drug that is granted subsequent FDA approval for a new rare disease indication. Yet the economic impact of such proposals is rarely addressed. We found that for the thirteen FDA-approved drugs that gained supplemental approval for a rare disease indication from 2005 through 2010, the median projected cost of clinical trials leading to approval was $29.8 million. If the exclusivity extension had been in place, the median discounted financial gain to manufacturers would have been $94.6 million. Median net returns would have been $82.4 million, with higher returns for drugs with higher annual sales. Extending market exclusivity would provide substantial compensation to many manufacturers, particularly for top-selling products, far in excess of the cost of conducting these trials. Alternative strategies to incentivize the study of approved drugs for rare diseases may offer similar benefits at a lower cost. Project HOPE—The People-to-People Health Foundation, Inc.

  11. Petroleum products price regulation in Nov Scotia : a six-month review

    International Nuclear Information System (INIS)

    2007-03-01

    Gasoline pricing regulation was introduced in July 2006 in order to achieve the following 3 main objectives: (1) stabilize prices by reducing the frequency of price changes and creating more uniform pricing across the province, (2) maintain industry infrastructure by slowing or halting the decline in the dealer network, particularly in rural areas, by improving viability through regulated margins, and (3) minimize the cost to consumers since higher prices are expected to result from the actions needed to maintain price stability and the higher margins needed to maintain industry infrastructure. This report examined the extent to which these objectives were achieved and contained the findings and recommendations of a review of the first six months of gasoline price regulation in Nova Scotia. The report discussed the rationale for regulation, study objectives, approach, and warning signs. It also discussed gasoline regulation in Nova Scotia including how regulation works and implementing regulation. The Nova Scotia gasoline market was presented with reference to industry structure; pre-regulation competition and pricing; and how regulation may affect structure and competition. Last, the report discussed whether regulation was meeting the objectives and perspectives on regulation. Several recommendations were presented, such as reducing the benchmark price adjustment period from two weeks to one week; removing the price cap on full-serve gasoline; adopting a fixed and transparent formula for forward averaging and applying it at each adjustment; and considering a framework for regulatory review. 12 refs., 15 figs

    Full Text Available Background and objective: Stroke is an increasing problem in developing countries and is the principal cause of disability and dependency in the western world. This study aimed to find out the one- and six-month case fatality, dependency and recurrence rates of stroke in Erbil teaching hospitals. Methods: This hospital-based prospective study included 293 stroke patients hospitalized in Erbil teaching hospitals from January 1st, 2015 through December 31st, 2015. Stroke was diagnosed by a consultant internist or neurologist and confirmed by brain CT-scan and/or MRI. Patients were followed-up for six months, then one- and six-month outcomes were measured including case-fatality, dependency and recurrences rates. Results: The one and six month case fatality rates were 28.3% and 37.5%, respectively. The rates in females (33.3%, 42.6%, respectively were higher than that in males (23.7%, 32.9%, respectively, but there was no significant association between case-fatality rate and gender. A total of 74.3% and 45.4% of patients at one- and six-month were functionally dependent. The majority (88.9% of diabetic patients were functionally dependent. Also, the one and six month recurrence rates of stroke patients were 15.7% and 23.2%, respectively. For both one and six month post stroke more recurrence occurred from ischemic (16.2%, 14.3%, respectively than from hemorrhagic (24.5%, 19.5%, respectively strokes, but there was no significant association between the recurrence and stroke subtype (P = 0.691, P = 0.367, respectively. Conclusion: The reported outcomes are relatively comparable to that reported in other developing countries, although it is still more than the rates of developed countries. Outcome measures can help to give information and develop guidelines for clinical practice and research. Keywords: Stroke; Case fatality; Recurrence; Functional outcome.

    Objective This study aimed to determine the feasibility and preliminary efficacy of a post-operative telephone-based cognitive behavioral therapy intervention (Tele-CBT) in improving eating pathology and psychosocial functioning. Methods Six-month post-operative bariatric surgery patients (n = 19) received six sessions of Tele-CBT. Study outcome variables included binge eating (BES), emotional eating (EES), depressive symptoms (PHQ-9), and anxiety symptoms (GAD-7). Results Retention was 73.7 % post-intervention. Tele-CBT resulted in significant reductions in mean difference scores on BES, EES-Total, EES-Anxiety, EES-Anger, PHQ9, and GAD7. Tele-CBT patients experienced a mean weight loss of 8.62 ± 15.02 kg between 6-months post-surgery (pre-Tele-CBT) and 12-months post-surgery. Conclusions These preliminary results suggest that post-surgery Tele-CBT is feasible and can improve post-surgery symptoms of psychopathology in this uncontrolled study, supporting the need for a randomized controlled trial.

    Contradictory results have been reported regarding most delivery parameters as risk factors for urinary incontinence. We investigated the association between the incidence of urinary incontinence six months postpartum and single obstetric risk factors as well as combinations of risk factors. This study was based on the Norwegian Mother and Child Cohort Study, conducted by the Norwegian Institute of Public Health during 1998-2008. This substudy was based on 7561 primiparous women who were continent before and during pregnancy. Data were obtained from questionnaires answered at weeks 15 and 30 of pregnancy and six months postpartum. Data were linked to the Medical Birth Registry of Norway. Single and combined delivery- and neonatal parameters were analyzed by logistic regression analyses. Birthweight was associated with significantly higher risk of urinary incontinence six months postpartum [3541-4180 g: odds ratio (OR) 1.4, 95% confidence interval (CI) 1.2-1.6; >4180 g: OR 1.6, 95% CI 1.2-2.0]. Fetal presentation, obstetric anal sphincter injuries, episiotomy and epidural analgesia were not significantly associated with increased risk of urinary incontinence. The following combinations of risk factors among women delivering by spontaneous vaginal delivery increased the risk of urinary incontinence six months postpartum; birthweight ≥3540 g and ≥36 cm head circumference; birthweight ≥3540 g and forceps, birthweight ≥3540 g and episiotomy; and ≥36 cm head circumference and episiotomy. Some combinations of delivery parameters and neonatal parameters seem to act together and may increase the risk of incidence of urinary incontinence six months postpartum in a synergetic way. © 2017 Nordic Federation of Societies of Obstetrics and Gynecology.

    Background Gingival inflammation and periodontal disease are the common complications of fixed dental prosthesis. They can be overcome by good oral hygiene maintenance. Objective The objective of this study was to assess the oral hygiene and gingival condition in patients after placement of fixed dental prosthesis for a period of six months. It was also analyzed how factors like type of fixed dental prosthesis (Single crown, fixed partial denture) and material (Metal, Porcelain fused to metal) are statistically associated with oral hygiene and gingival health. Method The sample consisted of 50 patients visiting the Dental Outpatient Department of Dhulikhel Hospital. The oral examinations were conducted using basic diagnostic tools (Mouth mirror, periodontal probe and explorer). Teeth and gingiva were examined using the Plaque and Gingiva Index by Silness and Löe. The examinations were conducted after 14 days and six months after placement of fixed dental prosthesis along with the oral hygiene instructions. Paired sample t-test were done to find statistical association using SPSS 16.0. Result Our results revealed no significant difference in plaque index among patients with single crown whereas fixed partial denture showed statistical significance. No significant differences were found for type of material. The statistical analysis showed similar results for gingival index. Conclusion Our research showed that single crown had no significant difference on Plaque index and Gingival index of the patient after 14 days and six months, whereas, Fixed partial denture showed significant difference. Both metal and porcelain fused to metal crown revealed no statistically significant difference on Plaque index and Gingival index.

    fatigue and depressive symptoms are common among women in the postpartum period, and it has been proposed that fatigue is a risk factor for later depression. To progress this research, there is a need to clarify the conceptual and measurement issue of whether these two sets of symptoms are distinct constructs. There is also a need to determine whether they are distinct constructs beyond the postnatal period. The aim of the study was to assess the construct and discriminant validity of fatigue and depressive symptoms as measured by the SF-36 Vitality subscale (SF-36) and the Edinburgh Postnatal Depression Scale (EPDS) at six months and at four years post partum. data from over 1000 women participating in the Maternal Health Study, a longitudinal study of women׳s physical and psychological health and recovery after childbirth were used. confirmatory factor analysis revealed a two-factor model of fatigue and depressive symptoms represented as distinct but related constructs was a better fit to the data than a one-factor model of fatigue and depression sharing the same underlying construct at both six months and four years post partum. this study provides empirical evidence that maternal fatigue and depression in the first year after having a baby and at four years post partum are best understood as separate psychological constructs or experiences. The findings have important implications for clinical practice, in particular underlining the importance of differentiating tiredness from depression. Copyright © 2014 Elsevier Ltd.

    Full Text Available ABSTRACT OBJECTIVE To analyze if maternal mental health is associated with infant nutritional status at six month of age. METHODS A cross-sectional study with 228 six-month-old infants who used primary health care units of the city of Rio de Janeiro, Southeastern Brazil. Mean weight-for-length and mean weight-for-age were expressed in z-scores considering the 2006 World Health Organization reference curves. Maternal mental health was measured by the 12-item General Health Questionnaire. The following cutoff points were used: ≥ 3 for common mental disorders, ≥ 5 for more severe mental disorders, and ≥ 9 for depression. The statistical analysis employed adjusted linear regression models. RESULTS The prevalence of common mental disorders, more severe mental disorders and depression was 39.9%, 23.7%, and 8.3%, respectively. Children of women with more severe mental disorders had, on average, a weight-for-length 0.37 z-scores lower than children of women without this health harm (p = 0.026. We also observed that the weight-for-length indicator of children of depressed mothers was, on average, 0.67 z-scores lower than that of children of nondepressed women (p = 0.010. Maternal depression was associated with lower mean values of weight-for-age z-scores (p = 0.041. CONCLUSIONS Maternal mental health is positively related to the inadequacy of the nutritional status of infants at six months.

    Cleft palate is one of the most common congenital craniofacial deformities. Otitis media with effusion (OME) is a middle ear disease having a prevalence of almost 90% in patients with cleft palates. Tympanometry is a fast, safe, non-invasive, and easy tool for diagnosing middle ear disease qualitatively and quantitatively. Studies have been conducted using tympanometry to detect middle ear conditions in patients with cleft palates, but no research has studied tympanogram findings in patients with cleft palates in Indonesia. The aim of this study is to determine the tympanogram findings in Indonesian children aged six months to seven years with cleft palates. This is a cross-sectional study of 30 patients (17 males and 13 females) with Veau classification of palatal clefts aged six months to seven years (median 26.5 months) who underwent tympanometry examinations using a 226 Hztympanometer. Tympanograms were classified using the Jerger/Liden classification. Examinations of 58 ears found that type B tympanograms occurred most frequently (70.7%). The quantitative values of tympanometry analyzed included SAA (0.1-0.2 cm3), TPP value (-197.2-(-146.8 daPa)), Vec value (0.5-0.6 cm3), and gradient value (0.03-0.07 cm3). Using the Fisher test, a significant relationship was found between age and type of tympanogram (p = 0.0039) with the risk of type B and C tympanograms in infants (6-60 months) as high as 4.8 times that of children without cleft palates. The type B tympanogram was most frequently seen in patients with cleft palates aged six months to seven years old with the quantitative values of tympanometry lower than the normal values. Therefore, there was a significant difference in the type of tympanogram seen with age.

    Premature loss of primary maxillary first molars has been associated with a number of consequences (such as tipping of the first permanent molar). The aim of the authors' study was to investigate dental-arch space problems arising as a result of premature loss of a primary maxillary first molar. This study was composed of 19 children who experienced unilateral premature loss of a primary maxillary first molar. The authors used each patient's intact contralateral arch segment as a control. The authors obtained maxillary dental study casts two or three days after the tooth was extracted, as well as six months later. The D + E space from the extraction side six months after removal of the tooth (mean +/- standard deviation, 15.62 +/- 1.13 millimeters) was significantly smaller than the space on the control side (16.88 +/- 1.12 mm) and the initial D + E space (16.70 +/- 0.69 mm). The authors found a significantly shorter arch length (25.47 +/- 1.58 mm) and larger intercanine width (31.29 +/- 2.49 mm) six months after the tooth was extracted compared with the initial arch length (25.66 +/- 1.64 mm) and intercanine width (30.42 +/- 2.64 mm). The early space changes to the maxillary arch subsequent to premature loss of a primary maxillary first molar are primarily distal drift of the primary canines toward the extraction space and palatal migration of the maxillary incisors. Although 1 mm of space was lost, which is statistically significant, this is not likely to be of sufficient clinical significance to warrant use of a space maintainer. If palatal movement appears to be needed, the dentist should consider use of a palatal arch rather than a band-and-loop maintainer. The effects of space maintainers need to be re-evaluated in cases of unilateral premature loss of a primary maxillary first molar.

    Increased activation of the sympathetic nervous system plays a central role in the pathophysiology of hypertension (HTN). Catheter-based renal denervation (RDN) was recently developed for the treatment of resistant HTN. To assess the safety and efficacy of RDN for blood pressure (BP) reduction at six months in patients with resistant HTN. In this prospective registry of patients with essential resistant HTN who underwent RDN between July 2011 and May 2013, the efficacy of RDN was defined as ≥ 10 mm Hg reduction in office systolic blood pressure (SBP) six months after the intervention. In a resistant HTN outpatient clinic, 177 consecutive patients were evaluated, of whom 34 underwent RDN (age 62.7 ± 7.6 years; 50.0% male). There were no vascular complications, either at the access site or in the renal arteries. Of the 22 patients with complete six-month follow-up, the response rate was 81.8% (n=18). The mean office SBP reduction was 22 mm Hg (174 ± 23 vs. 152 ± 22 mm Hg; p<0.001) and 9 mm Hg in diastolic BP (89 ± 16 vs. 80 ± 11 mm Hg; p=0.006). The number of antihypertensive drugs (5.5 ± 1.0 vs. 4.6 ± 1.1; p=0.010) and pharmacological classes (5.4 ± 0.7 vs. 4.6 ± 1.1; p=0.009) also decreased significantly. Of the 24-hour ambulatory BP monitoring and echocardiographic parameters analyzed, there were significant reductions in diastolic load (45 ± 29 vs. 27 ± 26%; p=0.049) and in left ventricular mass index (174 ± 56 vs. 158 ± 60 g/m(2); p=0.014). In this cohort of patients with resistant HTN, RDN was safe and effective, with a significant BP reduction at six-month follow-up. Copyright © 2013 Sociedade Portuguesa de Cardiologia.

    Full Text Available Abstract Introduction The purpose of this long-term clinical study was to examine the additional efficacy of photodynamic therapy (PDT to scaling and root planing (SRP in patients with chronic periodontal disease. Methods A total of 22 patients (mean age: 59.3 ± 11.7 years with chronic periodontal disease and four teeth with probing depth ≥ 5 mm were enrolled in the study. Inclusion criteria were: no systemic disease, no smoking, no pregnancy and no long-term medication. Beside the anamnesis, the following clinical parameters were assessed at baseline (one week before therapy, and one, three and six months after the therapy: bleeding on probing (BOP, plaque index (PI probing depth (PD, and clinical attachment loss. All measurements were done by the same examiner with a fixed periodontal probe (PCP 12, Hu-Friedy at six measurements/tooth. In each patient, two teeth were treated with SRP alone and two teeth with SRP and PDT (Periowave, Ondine Biopharma, Vancouver, Canada. The nonparametric Wilcoxon test for paired samples was used for comparison of the effect of the two treatments (p ≤ 0.05. Results After both types of treatment, the number of teeth positive for BOP declined. At baseline, the CAL measured 7.2 ± 1.2 mm (SRP or 8.1 ± 1.3 mm (SRP/PDT; one, three and six months after both types of treatment an improvement was observed. At baseline, the probing depth was 5.9 ± 0.8 mm (SRP or 6.4 ± 0.8 mm (SRP/PDT; after six months, an improvement of 2.4 ± 0.6 mm (SRP or 2.9 ± 0.8 mm (SRP/PDT was found. The greater reduction of the PD, achieved by a combination of SRP/PDT, was statistically significant after six months (p = 0.007. Conclusion This clinical study demonstrates that SRP in combination with PDT seems to be effective and is therefore suitable as an adjuvant therapy to the mechanical conditioning of the periodontal pockets in patients with chronic periodontal diseases.

    Cutaneous larva migrans is a distinctive serpiginous eruption caused by a reaction to burrowing hookworms. The infection is usually self-limited, normally lasting 2-8 weeks, but may persist for more than a year if misdiagnosed. Biopsies of the creeping eruption rarely reveal an organism. Thus, it is important for the infection to be recognized clinically, so that effective treatment may begin. We found topical thiabendazole to be fast and effective in treating this case of cutaneous larva migrans of six months' duration.

    Full Text Available Aim: The aim of this study was to find out how the health literacy of primiparae in the first six months of motherhood is examined. The following research questions were raised: What methods are used to examine maternal health literacy? What aspects of maternal health literacy are investigated? Do the results prove any link between maternal health literacy and child health? Design: Review. Methods: The search for primary research studies was based on a combination of the following keywords: health literacy, mother*, maternity*, information, and knowledge in the Scopus and Web of Science databases. Exclusion criteria: not a primary study, does not concern research on primiparae of children under six months, unrelated to health literacy research or obtaining of information and acquiring of knowledge, not available in full-text, or clear research methodology description not available. The data were processed using thematic analysis based on the sorting method. Results: 31 studies were found, 17 of which were analysed. The majority of studies used quantitative methods of research with standardized tools. The key categories of health literacy related to obtaining, understanding and use of health information. No direct correlation was clearly demonstrated between level of maternal health literacy and child health. Conclusion: The trend in terms of the focus and goals of professional studies, regardless of cultural or national context, is a shift away from examining the way information is acquired to how it is understood by mothers.

    Stress hormones have been associated with temporal discounting. Although time-discount rate is shown to be stable over a long term, no study to date examines whether individual differences in stress hormones could predict individuals' time-discount rates in the relatively distant future (e.g., six month later), which is of interest in neuroeconomics of stress-addiction association. We assessed 87 participants' salivary stress hormone (cortisol, cortisone, and alpha-amylase) levels and hyperbolic discounting of delayed rewards consisting of three magnitudes, at the time-interval of six months. For salivary steroid assays, we employed a liquid chromatography/ mass spectroscopy (LC/MS) method. The correlations between the stress hormone levels and time-discount rates were examined. We observed that salivary alpha-amylase (sAA) levels were negatively associated with time-discount rates in never-smokers. Notably, salivary levels of stress steroids (i.e., cortisol and cortisone) negatively and positively related to time-discount rates in men and women, respectively, in never-smokers. Ever-smokers' discount rates were not predicted from these stress hormone levels. Individual differences in stress hormone levels predict impulsivity in temporal discounting in the future. There are sex differences in the effect of stress steroids on temporal discounting; while there was no sex defference in the relationship between sAA and temporal discounting.

    To examine the efficacy of a smoking prevention program which aimed to address smoking related cognitions and smoking behavior among Saudi adolescents age 13 to 15. A randomized controlled trial was used. Respondents in the experimental group (N=698) received five in-school sessions, while those in the control group (N=683) received no smoking prevention information (usual curriculum). Post-intervention data was collected six months after baseline. Logistic regression analysis was applied to assess effects on smoking initiation, and linear regression analysis was applied to assess changes in beliefs and analysis of covariance (ANCOVA) was used to assess intervention effects. All analyses were adjusted for the nested structure of students within schools. At post-intervention respondents from the experimental group reported in comparison with those from the control group a significantly more negative attitude towards smoking, stronger social norms against smoking, higher self-efficacy towards non-smoking, more action planning to remain a non-smoker, and lower intentions to smoke in the future. Smoking initiation was 3.2% in the experimental group and 8.8% in the control group (pnon-smoking cognitions and non-smoking behavior. Therefore it is recommended to implement the program at a national level in Saudi-Arabia. Future studies are recommended to assess long term program effects and the conditions favoring national implementation of the program. Copyright © 2016 Elsevier Inc. All rights reserved.

    Interpretation & conclusions: Most HEI lacked measles antibodies at six months age and were, therefore, more vulnerable to measles than HUnI. Seroconversion in response to a single dose of measles vaccine administered at six months age was low in these infants, signifying the need of additional dose(s of measles/measles-containing vaccine.

  18. Malignant Transformation Six Months after Removal of Intracranial Epidermoid Cyst: A Case Report

    2011-01-01

    Full Text Available Intracranial epidermoid cysts are uncommon benign tumors of developmental origin; malignant transformation of benign epidermoid cysts is rare, and their prognosis remains poor. We report a case of squamous cell carcinoma arising in the cerebellopontine angle. A 52-year-old man presented with left facial paralysis and cerebellar ataxia. He had undergone total removal of a benign epidermoid cyst six months previously. Postoperative magnetic resonance imaging of the brain revealed a heterogeneous and cystic lesion in the left cerebellopontine angle with hydrocephalus. The cyst wall was enhanced by gadolinium. He underwent ventricle-peritoneal shunt and removal again; the histopathological examination revealed a squamous cell carcinoma possibly arising from an underlying epidermoid cyst. This entity is being reported for its rarity. The presence of contrast enhancement at the site of an epidermoid cyst combined with an acute, progressive neurological deficit should alert the neurosurgeon to the possibility of a malignant transformation.

    Research findings have developed a troubling narrative of youth leaving foster care. Congress attempted to address the post-discharge difficulties of foster youth by passing the Independent Living Initiative in 1986, which mandated that the states develop services that would prepare youth for life after foster care. However, it is unclear what effect these programs have on post-foster care trajectories. This largely qualitative study examined the perceptions of a sample of discharged foster six months after leaving care. Most youth felt prepared for life and foster care. They were also for the most part were satisfied with their independent living program, but had significant dissatisfactions with elements of the program. These satisfactions and dissatisfactions are reported along with suggestions for improvement. The policy and practice implications of these suggestions are considered.

    Purpose To evaluate postoperative clinical outcomes, and corneal High Order Aberrations, among eyes with hyperopia up to +5 D of spherical equivalent, that have undergone LASIK treatments using the SCHWIND AMARIS laser system. Methods At six-month follow-up, 100 eyes with preoperative hyperopia or hyperopic astigmatism up to +5 D of spherical equivalent were retrospectively analysed. Standard examinations, pre- and postoperative wavefront analysis with a corneal-wavefront-analyzer (OPTIKON Scout) were performed. Aberration-Free aspheric treatments were planned with Custom Ablation Manager software and ablations performed using the SCHWIND AMARIS flying-spot excimer laser system (both SCHWIND eye-tech-solutions). LASIK flaps were created using a LDV femtosecond laser (Ziemer Group) in all cases. Clinical outcomes were evaluated in terms of predictability, refractive outcome, safety, and wavefront aberration. Results At six month, 90 % of eyes achieved ≥ 20/25 UCVA and 44 % achieved ≥ 20/16 UCVA. Seventy-four percent of eyes were within ± 0.25D of spherical equivalent and 89 % within ± 0.50D, with 94 % within 0.50D of astigmatism. Mean spherical equivalent was −0.12 ± 0.51D and 0.50 ± 0.51D for the astigmatism. Fifty-two percent of eyes improved BSCVA vs. only 19 % losing lines of BSCVA. Predictability slope for refraction was 1.03 and intercept +0.01 D. On average, negative corneal spherical aberrations were significantly increased by the treatments, no other aberration terms changed from pre- to postoperative values. Conclusions LASIK for hyperopia and hyperopic astigmatism with SCHWIND AMARIS yields very satisfactory visual outcomes. Preoperative refractions were postoperatively reduced to subclinical values with no clinically relevant induction of corneal HOA.

    The authors assessed 23 subjects immediately before and six months (27.5 weeks) after their first ayahuasca experience in an urban Brazilian religious setting, either Santo Daime (N = 15) or União do Vegetal (N = 8). Measures included scores on instruments assessing psychiatric symptoms, personality variables and quality of life. Independent variables were the frequency of ayahuasca use throughout the period and the length of ayahuasca wash-out after six months. Santo Daime subjects had a significant reduction of minor psychiatric symptoms, improvement of mental health, and a change in attitude towards more confidence and optimism. The União do Vegetal group had a significant decrease in physical pain, and attitude change towards more independence. Independence was positively correlated with the frequency of ayahuasca use and negatively correlated with the wash-out period. We discuss possible mechanisms by which these changes may occur and suggest areas for future research.

    Full Text Available Abstract Background A considerable gap exists in regard to longitudinal research on quality of life (QoL in community populations of children and adolescents. Changes and stability of QoL have been poorly examined, despite the fact that children and adolescents undergo profound developmental changes. The aims of the study were to investigate short-term changes in student QoL with regard to sex and age in a school-based sample. Methods A representative Norwegian sample of 1,821 school children, aged 8–16 years and their parents were tested at baseline and 6 months later, using the Inventory of Life Quality for Children and Adolescents (ILC and the Kinder Lebensqualität Fragebogen (KINDL. Student response rate at baseline was 71.2% and attrition over the follow-up period was 4.6%, and 1,336 parents (70% completed the follow-up. Change scores between baseline and follow-up evaluations were analysed by means of ANCOVA in regard to sex and age effects. Results Students in the 8th grade reported a decrease in QoL over the six-month follow-up period as compared to those in the 6th grade with regard to Family and School domains and total QoL on the KINDL. For emotional well-being a significant linear decrease in QoL across grades 6th to 10th was observed. However, student ratings on the Friends and Self-esteem domains did not change significantly by age. Girls reported a higher decrease in their QoL across all grades over the follow-up period than did boys in respect of Self-esteem on the KINDL, and an age-related decrease in total QoL between 6th and 8th grade on the ILC. Parent reports of changes in child QoL were nonsignificant on most of the domains. Conclusion The observed age and sex-related changes in school children's QoL across the six-month follow-up period should be considered in epidemiological as well as clinical research.

    Full Text Available INTRODUCTION: Cardiovascular diseases are the leading cause of death in Europe and they account for 40% of all fatal cases among patients under 75 years. The incidence of out-of-hospital cardiac arrests (OHCA that were managed by EMS in Europe, including all rhythmes, varies between 38 and 86 per 100 000 people. Epidemiological data on sudden cardiac arrest in Republic of Serbia were not known before Eureca ONE study. AIM: The aim of this paper is to point out the importance of researching cardiac arrest, and the first results of EURECA SERBIA programme 2014. will enable comparison of resuscitation procedures quality and survival rate, both within our country, and relative to European participants. MATERIALS AND METHODS: Prospective study. Data were gathered through specific questionnaire during the period of six months, from October 1, 2014 to April 1, 2015. This qustionnaire covered all patients that have had OHCA on the territory of Subotica, and were treated by the EMS. In cases with achieved ROSC, survival was monitored after a month. RESULTS: Emergency medical service of Subotica covers the territory with 141 554 citizens. Cardiac arrest was recorded in 46 patients that EMS treated. The incidence of OHCA during six month period was 32,5/100 000. Number of initiated resuscitations is 44, i.e. 31,08/100 000. The most often place of OHCA event was patient's home (27 61%, or 19, 07/100 000. Heart condition was the cause of OHCA in 100% of all cases (44, that is 31, 08/100 000. 15 patients (34,09% or 10,6/100 000 achieved ROSC, and 12 (27%, that is 8,47/100 000 had pulse and measurable blood pressure at hospital door. 6 patients of all hospitalized were discharged (4,23/100 000, and the incidence of survival after 30 days was 4,23/100 0. ' CONCLUSION: EuReCa One 2014 programme enables inclusion into European register of out-of-hospital cardiac arrest. There are differences in observed variables that cannot be explained by precise definition of

    The aim of this study was to study the cross-sectional and longitudinal associations between mindfulness facets and problematic Internet use in adolescents. The sample consisted of 609 adolescents (313 girls, 296 boys; Mean age=14.21years, SD=1.71; age range 11-18). Participants completed a measure of five facets of mindfulness (describing, observing, acting with awareness, non-judging and non-reacting) at the beginning of the year, and measures of several components of problematic Internet use (preference for online social interactions, the use of the Internet to regulate mood, deficient self-regulation and negative outcomes) at beginning of the year and six months later. Findings indicated that non-judging is the only dimension of mindfulness that predicts a decrease in preference for online social interactions over face-to-face relationships. Moreover, non-judging indirectly predicted reductions in the rest of the problematic Internet use components. The observing and acting with awareness dimensions of mindfulness directly predicted less deficient self-regulation of Internet use and indirectly predicted less negative outcomes through their impact on deficient self-regulation. Thus, these dimensions seem to act when the maladaptive use of the Internet is consolidated. These findings suggest that interventions should include approaches to develop those mindfulness facets that protect against the development of problematic Internet use.

    Twenty-six children with primary brain tumors were studied prospectively with regard to their sensorimotor, intellectual, academic, and emotional status. Serial evaluations were conducted after surgery (pre-irradiation) and six months after the completion of radiation therapy. The timing of the second evaluation was chosen so as to antedate the late effects of irradiation. Children over 6 years old displayed significant improvement of intellectual function over time, with only 11% exhibiting deterioration on one or more cognitive parameters. In contrast, 68% of younger children clinically deteriorated in one or more areas of intellectual functioning, with prominent difficulties in memory and selective attention for age. Children under 6 years old with supratentorial tumors were less likely than those with posterior fossa tumors to improve their cognitive performance. At the second evaluation, 23% of the patients were functioning below normal (IQ less than 80) intellectually, with 50% of the younger children and 11% of the older children receiving special educational assistance. Approximately 40-50% of the patients manifested emotional adjustment problems at each evaluation. The results are discussed in terms of the clinical need to follow similar patient populations with formal psychological assessments over time, and in terms of the difficulties involved in defining factors that determine the functional status of children surviving brain tumors

    Background Post-stroke fatigue is common and disabling. Objectives The aim of NotFAST was to examine factors associated with fatigue in stroke survivors without depression, six months after stroke. Methods Participants were recruited from four UK stroke units. Those with high levels of depressive symptoms (score ≥7 on Brief Assessment Schedule Depression Cards) or aphasia were excluded. Follow-up assessment was conducted at six months after stroke. They were assessed on the Fatigue Severity Scale, Rivermead Mobility Index, Nottingham Extended Activities of Daily Living scale, Barthel Index, Beck Anxiety Index, Brief Assessment Schedule Depression Cards, Impact of Event Scale-Revised, and Sleep Hygiene Index. Results Of the 371 participants recruited, 263 (71%) were contacted at six months after stroke and 213 (57%) returned questionnaires. Approximately half (n = 109, 51%) reported fatigue at six months. Of those reporting fatigue initially (n = 88), 61 (69%) continued to report fatigue. 'De novo' (new) fatigue was reported by 48 (38%) of those not fatigued initially. Lower Nottingham Extended Activities of Daily Living scores and higher Beck Anxiety Index scores were independently associated with fatigue at six months. Conclusions Half the stroke survivors reported fatigue at six months post-stroke. Reduced independence in activities of daily living and higher anxiety levels were associated with the level of fatigue. Persistent and delayed onset fatigue may affect independence and participation in rehabilitation, and these findings should be used to inform the development of appropriate interventions.

    Full Text Available OBJECTIVE: Evaluation of the clinical signs and symptoms predicting bacterial and viral pneumonia, in accordance with the Brazilian National Control Program for Acute Respiratory (ARI. METHODS: Observational prospective study. Seventy-six children from birth to six months of age who had pneumonia were studied in the emergency room. The patients were subdivided into two groups, based on radiological findings (gold-standard: 47 had bacterial pneumonia, and 29 had viral pneumonia. The frequencies, sensitivities, and specificities of the signs and symptoms were evaluated. RESULTS: The sensibilities and sensitivities of general findings in bacterial pneumonia were, respectively: fever 53.2%/40.0%; hypoactivity 68.4%/55.6% and prostration detected by the doctor 72.7%/55.0%. The same findings in viral pneumonias showed, respectively: 37.9%/40.0%, 66.7%/55.6% and 66.7%/55.6%. The sensibilities and sensitivities of respiratory findings in bacterial pneumonia were, respectively: coughing 66.0/38.1%, Respiratory rate = 50 ripm 76.6%/38.1%, altered respiratory auscultation 91.3%/10.5%, and chest indrawing 46.7%/80.0%. The same findings in viral pneumonias were, respectively: 69.0%/38.1%, 86.2%/38.1%, 85.7%/10.5% and 44.8%/80.0%. CONCLUSION: Analysis of signs and symptoms in each group did not distinguish bacterial from viral pneumonia. Our findings reinforce the adequacy of the ARI program in Brazil, which gives an early diagnosis of pneumonia, independent of its etiology.

The objective was to evaluate the effects of long-term royal jelly ingestion on humans. Methods We conducted a randomized placebo-controlled, double-blind trial. A total of 61 healthy volunteers aged 42-83 years were enrolled and were randomly divided into a royal jelly group (n = 31 and a control group (n = 30. Three thousand mg of royal jelly (RJ or a placebo in 100 ml liquid/day were ingested for 6 months. The primary outcomes were changes in anthropometric measurements and biochemical indexes from baseline to 6 months after intervention. Results Thirty subjects in the RJ group and 26 in the control group were included in the analysis of endpoints. In an adjusted mean change of the variables from the baseline, significant differences between the two groups could be found in red blood cell counts (+0.16x106 /μL for the RJ group vs. -0.01x106 /μL for the control group, P = 0.0134, hematocrit (+0.9% vs. -0.8%, P = 0.0251, log (fasting plasma glucose (+0.01 ± 0.01 log mg/dL vs. +0.05 ± 0.01 log mg/dL, P = 0.0297, log (insulinogenic index (+0.25 vs. -0.13, P = 0.0319, log dehydroepiandrosterone sulfate (DHEA-S (+0.08 log μg/dL vs. +0.20 log μg/dL, P = 0.0483, log testosterone (T (+0.12 ± 0.04 log ng/mL vs. -0.02 ± 0.05 log ng/mL, P = 0.0416, log T/DHEA-S ratio (+0.05 ± 0.05 vs. -0.23 ± 0.59, P = 0.0015, and in one of the SF-36 subscale scores, mental health (MH (+4 vs. -7, P = 0.0276. Conclusions Six-month ingestion of RJ in humans improved erythropoiesis, glucose tolerance and mental health. Acceleration of conversion from DHEA-S to T by RJ may have been observed among these favorable effects.

    The goal of this study was to evaluate the 1-week, 3-month, and 6-month performance of eight commercially available one-bottle adhesive systems to dentin. Lingual and buccal surfaces from human third molars were ground wet on 600-grit SiC paper to obtain a flat dentinal surface. The specimens were randomly divided into 24 groups (n = 10), which were established to measure the shear bond strengths of Bond-1 (B1), ONE-STEP (OS), OptiBond SOLO (OP), Prime & Bond 2.1 (PB), Single Bond (SB), STAE (ST), Syntac Sprint (SS), and Tenure Quick (TQ) after 1-week, 3-month, and 6-month water storage at 37 degrees C. One-bottle adhesives were applied according to manufacturers' instructions and Z100 composite cylinders were applied on the bonded dentinal surfaces. The 3-month water-storage groups were thermocycled for 1500 cycles at 5 degrees C and 55 degrees C and 6-month groups for 3000 cycles. After storage periods, specimens were tested in shear in a universal testing machine (0.5 mm/min). were statistically analyzed by analysis of variance and Tukey test. Results: The changes in shear bond strengths were not uniform over time. Over the test period, OS, PB, SB, and SS exhibited bond strength stability, however, SS presented low bond strengths on all tested periods. A significant decrease in bond strength was observed for B1, OP, ST, and TQ after the 6-month storage period.

    No research currently exists predicating a link between the injury-affiliated sensorimotor deficits of acute ankle sprain and those of chronic ankle instability during gait. This analysis evaluates participants with a 6-month history of ankle sprain injury to affirm this link. 69 participants with a 6-month history of acute first-time lateral ankle sprain were divided into subgroups ('chronic ankle instability' and 'coper') based on their self-reported disability and compared to 20 non-injured participants during a gait task. Lower extremity kinematic and kinetic data were collected from 200 ms pre- to 200 ms post-heel strike (period 1) and from 200 ms pre- to 200 ms post-toe off (period 2). The 'chronic ankle instability' subgroup (who reported greater disability) displayed increased knee flexion during period 1. During period 2, this subgroup exhibited greater total displacement at their ankle joint and greater extensor dominance at their knee. That many of these features are present, both in individuals with acute ankle sprain and those with chronic ankle instability may advocate a link between acute deficits and long-term outcome. Clinicians must be aware that the sensorimotor deficits of ankle sprain may persevere beyond the acute stage of injury and be cognizant of the capacity for impairments to pervade proximally. © Georg Thieme Verlag KG Stuttgart · New York.

  5. Cost-utility of a six-month programmed sports therapy (PST) in patients with haemophilia.

    Recurrent musculoskeletal haemorrhages in people with haemophilia (PwH) lead to restrictions in the locomotor system and, as a result, in physical performance, too. Due to its physical and psychological benefits, sport is increasingly re-commended for haemophilic patients. Evidence on the cost-effectiveness of sports therapy is still lacking. The aim of this study was to determine the cost-effectiveness of a 6-month programmed sports therapy (PST). The cost-effectiveness of the 6-month PST was assessed from a societal perspective alongside a RCT using cost-utility analysis. The analysis included 50 PwH with moderate-to-severe haemophilia A and B and a training period over 6 months. The health-related quality of life was measured with the EuroQoL-domain questionnaire. Resource utilization was assessed by questionnaire before and after the intervention. A cost-effectiveness acceptability curve was constructed, and sensitivity analyses were performed. During the 6-month study period, mean adjusted total healthcare costs were lower (mean difference: -22 805 EUR; 95%-CI: -73 944-48 463; P = .59) and the number of QALYs was higher in the intervention group (mean difference: 0.3733; 95%-CI: 0.0014-0.0573; P = .04). The probability of an incremental cost-effectiveness ratio <50 000 EUR per QALY was 71%. The performed sensitivity analysis confirmed these results. Results showed that the PST is effective in terms of a significant gain of QALYs. Furthermore, results weakly indicate the potential of the PST to reduce healthcare costs. Future studies should expand the observation period to have a closer look at the influence of PST on lifetime costs. © 2018 John Wiley & Sons Ltd.

    Full Text Available Abstract Background The validity of Health-Related Quality of Life (HRQOL recalled by ICU admitted patients have not been published. The aim of this study was to compare the baseline HRQOL measured before surgery and ICU admission with that recalled at 3 and 6 months in a population of patients with planned ICU admission after surgery. Methods This prospective study was performed in three Italian centres on patients who had undergone General, Orthopaedic or Urologic surgery. All adult patients with planned ICU admission between October 2007 and July 2008 were considered for enrolment. At hospital admission, the Mini Mental Status Examination and EuroQoL (EQ questionnaire (referring to the last two weeks were administered to the patients who consented. Three and six months after ICU admission, the researchers administered by phone the EQ questionnaire and Post-Traumatic Stress Syndrome 14 questions Inventory, asking the patients to rate their HRQOL before surgery and ICU admission. Past medical history demographic and clinical ICU-related variables were collected. Statistical analysis Chi-square test and non parametric statistics were used to compare groups of patients. The EQ-5D was transformed in the time trade-off (TTO to obtain a continuous variable, subsequently analysed using the Intraclass Correlation Coefficient (ICC. Results Of the 104 patients assessed at baseline and discharged from the hospital, 93 had the EQ administered at 3 months, and 89 at 6 months. The ICC for TTO recalled at 3 months vs pre-ICU TTO was 0.851, and that for TTO recalled at 6 months vs pre-ICU TTO was 0.833. The ICC for the EQ-VAS recalled at 3 months vs pre-ICU EQ-VAS was 0.648, and that for the EQ-VAS recalled at 6 months vs pre-ICU EQ-VAS was 0.580. Forty-two (45% patients assessed at 3 months gave the same score in all EQ-5D items as at baseline. They underwent mainly orthopaedic surgery (p 0.011, and perceived the severity of their illness as lower (p 0

    To examine the effect of parents' occupational and life exposure during six months before pregnancy on executive function of preschool children. Pregnant women involved in the study came from the Ma'anshan Birth Cohort Study,a part of the China-Anhui Birth Cohort Study. Between October 2008 and October 2010, pregnant women who accepted pregnancy care in four municipal medical and health institutions in Ma'anshan city were recruited as study objects. A total of 5,084 pregnant women and 4,669 singleton live births entered in this cohort. Between April 2014 and April 2015, a total of 3,803 pre-school children were followed up. Finally, except 32 preschool children did not have EF evaluation result, there were 3,771 children included in this study. By using self-designed " Maternal health handbook", we researched parents' general demographic characteristics, and life and occupational exposure during six months before pregnancy. To research preschool children's executive function, we used the Behavior Rating Inventory of Executive Function-Preschool Version (BRIEF-P). Univariate and multivariate statistical method was used to analyze the association of parents' life and occupational exposure during six months before pregnancy and preschool children's EF. 3,771 preschool children's detected rate of inhibitory self-control index (ISCI), flexibility index (FI), emergent metacognition index (EMI) and global executive composite (GEC) dysplasia were 4.8% (182), 2.3% (88), 16.5% (623) and 8.6% (324) respectively. During six months before pregnancy, children whose parents were lived in a noise environment (OR=1.86, 95% CI: 1.36-2.54), whose maternal were exposed to pesticides were the risk of ISCI dysplasia(OR=3.60, 95% CI: 1.45-8.95). During six months before pregnancy, children whose maternal were exposed to pesticides (OR=6.72, 95% CI: 2.50-18.07) and whose father were exposed to occupational lead (OR=2.10, 95% CI: 1.25-3.54) were the risk of FI dysplasia.

  9. A Different View of Solar Spectral Irradiance Variations: Modeling Total Energy over Six-Month Intervals.

    Woods, Thomas N; Snow, Martin; Harder, Jerald; Chapman, Gary; Cookson, Angela

    A different approach to studying solar spectral irradiance (SSI) variations, without the need for long-term (multi-year) instrument degradation corrections, is examining the total energy of the irradiance variation during 6-month periods. This duration is selected because a solar active region typically appears suddenly and then takes 5 to 7 months to decay and disperse back into the quiet-Sun network. The solar outburst energy, which is defined as the irradiance integrated over the 6-month period and thus includes the energy from all phases of active region evolution, could be considered the primary cause for the irradiance variations. Because solar cycle variation is the consequence of multiple active region outbursts, understanding the energy spectral variation may provide a reasonable estimate of the variations for the 11-year solar activity cycle. The moderate-term (6-month) variations from the Solar Radiation and Climate Experiment (SORCE) instruments can be decomposed into positive (in-phase with solar cycle) and negative (out-of-phase) contributions by modeling the variations using the San Fernando Observatory (SFO) facular excess and sunspot deficit proxies, respectively. These excess and deficit variations are fit over 6-month intervals every 2 months over the mission, and these fitted variations are then integrated over time for the 6-month energy. The dominant component indicates which wavelengths are in-phase and which are out-of-phase with solar activity. The results from this study indicate out-of-phase variations for the 1400 - 1600 nm range, with all other wavelengths having in-phase variations.

    Paroxetine titration may be difficult in older individuals as they are more sensitive to side effects. The current study extends to 6 months our previously published report in which paroxetine was started at 2.5 mg/day and slowly increased by 2.5 mg on alternate days (slow titration) or rapidly titrated to target dose from 10 mg/day (standard titration) in a naturalistic setting. Here, the follow-up period was extended to 26 weeks. We performed an intent-to-treat analysis of 47 subjects from the original sample (major depressive disorder and/or generalized anxiety disorder (GAD); >60 years of age). Missing evaluations were replaced by last observations carried forward. GAD was included as a stratification factor. Patients in whom paroxetine was slowly up-titrated were more likely to remit (84.0% vs 54.5%; p = 0.028) and had lower core depression (p = 0.0015) and psychic anxiety levels (p = 0.006) after 26 weeks. Dropout rate was 20% in the slow titration group compared with 77.3% in the standard titration arm (p titration groups in the subsample without GAD. Despite some limitations, these findings suggest that paroxetine treatment should be started at lower doses in older depressed patients and slowly up-titrated. This strategy would allow to increase antidepressant response and the likelihood of completing treatment cycle in patients with high anxiety levels and GAD comorbidity.

    Full Text Available BACKGROUND To compare and analyse the metabolic side effects of Risperidone and Haloperidol in newly diagnosed drug-naive schizophrenic disorder patients attending Govt. Stanley Medical College Hospital during initial 6 months of therapy. MATERIALS AND METHODS Newly diagnosed drug-naïve Schizophrenic Patients (n = 60 aged between 18 - 45 years are recruited and randomly allocated into Group A (Risperidone 4 - 6 mg daily and Group B (Haloperidol 5 - 10 mg daily after getting informed consent from the patient’s family members. Patients are followed up monthly for the occurrence of metabolic abnormalities like weight gain, rise in blood pressure, elevated fasting, post-prandial blood sugar level, dyslipidaemia for a period of 6 months. RESULTS Risperidone group showed the mean body weight increase from 64.40 to 69.27, SBP/DBP increase from 123.80/79 to 129.90/83.13; FBS/PPBS increase from 100.20/129.30 to 135.40/185.00; TC increase from 177.23 to 206.23; LDL from 124.30 to 158.30; HDL 48.83 to 50.07; TG 133.47 to 197.83: Haloperidol group showed the mean body weight increase from 64.07 to 68.48, SBP/DBP increase from 123.80/79.00 to 124.27/81.67; FBS/PPBS increase from 100.20/129.30 to 119.87/167.10; TC increase from 177.23 to 197.40; LDL from 119.77 to 139.00; HDL remained 48.83; TG 133.47 to 171.40. CONCLUSION This study showed that patients in both the groups had weight gain, rise in blood sugar, LDL cholesterol and Triglycerides level, but the rise was significant in patients on Risperidone when compared to those on Haloperidol during the 6-month followup.

    Al-Anon Family Groups, a 12-step mutual-help program for people concerned about another person's drinking, is the most widely used form of help by Concerned Others. This longitudinal study examined newcomers' outcomes of attending Al-Anon. Aims were to better understand early gains from Al-Anon to inform efforts in the professional community to facilitate concerned others' attendance of and engagement in Al-Anon. We compared two groups of Al-Anon newcomers who completed surveys at baseline and 6 months later: those who discontinued attendance by the 6-month follow-up (N = 133), and those who were still attending Al-Anon meetings (N = 97); baseline characteristics were controlled in these comparisons. Newcomers who sustained participation in Al-Anon over the first 6 months of attendance were more likely than those who discontinued participation during the same period to report gains in a variety of domains, such as learning how to handle problems due to the drinker, and increased well-being and functioning, including reduced verbal or physical abuse victimization. Newcomers to Al-Anon reported more personal gains than drinker-related gains. The most frequent drinker gain was a better relationship with the Concerned Other; attendees were more likely to report this, as well as daily, in-person contact with the drinker. Al-Anon participation may facilitate ongoing interaction between Concerned Others and drinkers, and help Concerned Others function and feel better. Thus, short-term participation may be beneficial. Health-care professionals should consider providing referrals to Al-Anon and monitoring early attendance.

    Method: An observational, longitudinal study was used to collect data from a conveniently selected sample of first-ever stroke patients. The Rivermead Motor Assessment Scale and the Barthel Index were used to determine functional outcome and the EQ-5D was used to collect information relating to quality of life at two months and six months poststroke. Descriptive and inferential statistics were used to analyse the data. Results: The total sample of 100 participants consisted of 50% men and 50% women with a mean age of 61 and a standard deviation of 10.55 years. Six-month quality of life datawas analysed for 73 of the 100 participants. Of the 27 who were lost to follow-up, nine participants died, four withdrew from the study after baseline data was collected and eleven could not be followed up as they had either moved or no follow-up telephone numbers were available. A further three participants were excluded from the analysis of the EQ-5D as they were aphasic. Of these, approximately 35% had problems with mobility and self-care, whilst 42% had severe problems with everyday activities and 37.8% expressed having anxiety and depression. Quality of life at two months (p = 0.010 and urinary incontinence (p = 0.002 were significant predictors of quality of life at six months. Conclusion: Health-related quality of life was decreased in the South African stroke sample. Functional ability and urinary incontinence were the factors affecting quality of life in the sample. These factors should be considered in the rehabilitation of stroke patients in these settings.

    Full Text Available Background. Injection with N-butyl-2-cyanoacrylate is a proven and successful therapeutic modality for treatment of patients with bleeding gastric varices. However, a variety of complications have also been associated with its use. Here, we report a rare case of retrogastric abscess which occurred almost six months after this therapy. This abscess was attributed to the hampered microbial clearance caused by the venous obliterations from N-butyl-2-cyanoacrylate. The abscess was successfully treated with 3 months of antibiotics.

    A six-month prospective study was conducted on the usefulness and usability of a representative electronic knowledge management tool, the WAX Active Library, for 19 general practitioners (GPs) evaluated using questionnaires and audit trail data. The number of pages accessed was highest in the final two months, when over half of the access trails were completed within 40 seconds. Most GPs rated the system as easy to learn, fast to use, and preferable to paper for providing information during consultations. Such tools could provide a medium for the activities of knowledge officers, help demand management, and promote sharing of information within primary care groups and across NHSnet or the Internet.

    Full Text Available BackgroundInfants and young children are at an increased risk ofmalnutrition from six months of age onwards, when breastmilk alone is no longer sufficient to meet all their nutritionalrequirements and complementary feeding should bestarted. Hence this study was undertaken to assess thepractices of complementary feeding.MethodThis hospital-based cross-sectional study was conducted attwo private hospitals – Dr TMA Pai Hospital Udupi and DrTMA Pai Hospital Karkala and a public hospital, RegionalAdvanced Paediatric Care Centre, Mangalore, of coastalsouth India for a two-month period from August 2010 toOctober 2010. Two-hundred mothers of children betweensix months and two years attending the paediatricoutpatient departments of the above-mentioned hospitalsfor growth monitoring, immunisation and minor illnessessuch as upper respiratory tract infections were selected forthe study. The subjects were selected for the study by theorder of their arrival to the outpatient department duringthe study period.ResultsIn the present study 77.5% mothers had startedcomplementary feeding at the recommended time of sixmonths. Only 32% of mothers were giving an adequatequantity of complementary feeds. The association ofinitiation of complementary feeding with socio-economicstatus, birth order, place of delivery and maternal educationwas found to be statistically significant. However thepractice of giving an adequate quantity of complementaryfeeds was significantly associated only with the place ofdelivery.ConclusionIn the present study, initiation of complementary feeding atthe recommended time of six months was seen in themajority of children. However the quantity ofcomplementary feeding was insufficient. Advice aboutbreast feeding and complementary feeding during antenatalcheck-ups and postnatal visits might improve feedingpractices.

Adult patients suffering mTBI without intracranial pathology on computed tomography (CT) from the prospective Transforming Research and Clinical Knowledge in Traumatic Brain Injury Pilot study with emergency department (ED) Glasgow Coma Scale (GCS) 13-15 and recorded blood alcohol level (BAL) were extracted. BAL≥80-mg/dl was set as proxy for excessive use. Multivariable regression was performed for patients with six-month Glasgow Outcome Scale-Extended (GOSE; functional recovery) and Wechsler Adult Intelligence Scale Processing Speed Index Composite Score (WAIS-PSI; nonverbal processing speed), using BAL≥80-mg/dl and GOSE≤7; 38.1% vs. 11.5%; p=0.025) and lower WAIS-PSI (92.4±12.7, 30th-percentile vs. 105.1±11.7, 63rd-percentile; pGOSE≤7 and an adjusted mean decrease of 8.88-points (95% CI [0.67-17.09]; p=0.035) on WAIS-PSI. Day-of-injury BAL>80-mg/dl after uncomplicated mTBI was associated with decreased GCS score and prolongation of reported LOC. BAL may be a biomarker for impaired return to baseline function and decreased nonverbal processing speed at six-months postinjury. Future confirmatory studies are needed. Published by Elsevier Ltd.

    Gait biomechanics, sex, and obesity can contribute to suboptimal outcomes from primary total knee arthroplasty. The aims of this study were to i) determine if sex and/or obesity influence the amount of change in gait biomechanics from pre-surgery to six months post-surgery and; ii) assess if gait returns to normal in men and women. Three-dimensional gait analysis was performed on 43 patients undergoing primary total knee arthroplasty for knee osteoarthritis (pre- and six months post-operative) and 40 asymptomatic controls. Mixed linear regression models were fit to assess which factors influenced change in gait biomechanics within the arthroplasty cohort, and interaction terms were included to assess if biomechanics returned to normal following surgery.

    Iodine is important for normal growth and psychomotor development. While infants below 6 months of age receive iodine from breast milk or fortified infant formula, the introduction of complementary foods poses a serious risk for deteriorating iodine status. This cross-sectional analysis assessed the iodine status of six-month-old South African infants and explored its associations with feeding practices and psychomotor milestone development. Iodine concentrations were measured in infant (n = 386) and maternal (n = 371) urine (urinary iodine concentration [UIC]), and in breast milk (n = 257 [breast milk iodine concentrations]). Feeding practices and psychomotor milestone development were assessed in all infants. The median (25th-75th percentile) UIC in infants was 345 (213-596) μg/L and was significantly lower in stunted (302 [195-504] μg/L) than non-stunted (366 [225-641] μg/L) infants. Only 6.7% of infants were deficient. Maternal UIC (128 [81-216] μg/L; r s  = 0.218, p psychomotor developmental scores were observed. Our results suggest that iodine intake in the studied six-month-old infants was adequate. Iodine in breast milk and commercial infant cereals potentially contributed to this adequate intake. © 2016 John Wiley & Sons Ltd.

    This study aimed to examine the predictors of better self-care behavior in patients with heart failure (HF) in a home visiting program. This is a longitudinal study nested in a randomized controlled trial (ISRCTN01213862) in which the home-based educational intervention consisted of a six-month followup that included four home visits by a nurse, interspersed with four telephone calls. The self-care score was measured at baseline and at six months using the Brazilian version of the European Heart Failure Self-Care Behaviour Scale. The associations included eight variables: age, sex, schooling, having received the intervention, social support, income, comorbidities, and symptom severity. A simple linear regression model was developed using significant variables (P ≤ 0.20), followed by a multivariate model to determine the predictors of better self-care. One hundred eighty-eight patients completed the study. A better self-care behavior was associated with patients who received intervention (P < 0.001), had more years of schooling (P = 0.016), and had more comorbidities (P = 0.008). Having received the intervention (P < 0.001) and having a greater number of comorbidities (P = 0.038) were predictors of better self-care. In the multivariate regression model, being in the intervention group and having more comorbidities were a predictor of better self-care. PMID:24083023

    To evaluate the incidence of unprovoked seizures in children and the prevalence of related neurodevelopmental comorbidities at the time of the presumed first seizure and six months thereafter. The medical records of all children (0-18 years of age) seeking medical attention as the result of a first unprovoked seizure between September 1, 2001 and December 31, 2006, and registered in the population-based Stockholm Incidence Registry of Epilepsy (SIRE) were reviewed. Neurodevelopmental comorbidities were evaluated on the basis of the medical records from this first visit and from other healthcare during the following six months. The incidence of unprovoked seizures was between 30 and 204/100,000 person years (n=766) in the different age groups. It was highest among the youngest children and lowest among the 18-year-olds with small gender differences. The most common neurodevelopment comorbidities were developmental delay (22%, CI: 19-25%), speech/language and learning difficulties (23%, CI: 20-26%) and intellectual disability (16%, CI: 13-18%). The types of neurodevelopmental comorbidity varied by age at the time of seizure onset, with cerebral palsy being more common among the 0-5-year-olds, attention deficits among the 6-16-year-olds, and autism and psychiatric diagnosis among the older children. An associated neurodevelopmental comorbidity was more common among those experiencing recurrent than single seizures during follow-up six months from the index seizure (42% versus 66%). In 68% (CI: 64-71%) of the children there was no known or suspected neurodevelopmental comorbidity. The incidence of unprovoked, non-febrile seizures among 0-18-year-olds included in the SIRE was 67/100,000 person-years. Neurodevelopmental comorbidities were common already at the time of onset of the seizure disorder, indicating that neither seizure treatment nor seizures were the underlying cause of other neurodevelopmental symptoms in these patients during the period studied.

    The majority of individuals report a decline in health-related quality of life following a stroke. Quality of life and factors predicting quality of life could differ in individuals from lower income countries. The aim of this study was therefore to determine the quality of life and factors influencing quality of life of community-dwelling stroke patients living in low-income, peri-urban areas in the Western Cape, South Africa. An observational, longitudinal study was used to collect data from a conveniently selected sample of first-ever stroke patients. The Rivermead Motor Assessment Scale and the Barthel Index were used to determine functional outcome and the EQ-5D was used to collect information relating to quality of life at two months and six months poststroke. Descriptive and inferential statistics were used to analyse the data. The total sample of 100 participants consisted of 50% men and 50% women with a mean age of 61 and a standard deviation of 10.55 years. Six-month quality of life data was analysed for 73 of the 100 participants. Of the 27 who were lost to follow-up, nine participants died, four withdrew from the study after baseline data was collected and eleven could not be followed up as they had either moved or no follow-up telephone numbers were available. A further three participants were excluded from the analysis of the EQ-5D as they were aphasic. Of these, approximately 35% had problems with mobility and self-care, whilst 42% had severe problems with everyday activities and 37.8% expressed having anxiety and depression. Quality of life at two months ( p = 0.010) and urinary incontinence ( p = 0.002) were significant predictors of quality of life at six months. Health-related quality of life was decreased in the South African stroke sample. Functional ability and urinary incontinence were the factors affecting quality of life in the sample. These factors should be considered in the rehabilitation of stroke patients in these settings.

    Background Exercise training may have the potential to improve post-thrombotic syndrome, a frequent, chronic complication of deep venous thrombosis. We conducted a randomized controlled two-centre pilot trial to assess the feasibility of a multicentre-based evaluation of a six-month exercise training program to treat post-thrombotic syndrome and to obtain preliminary data on the effectiveness of such a program. Methods Patients were randomized to receive exercise training (a six-month trainer-supervised program) or control treatment (an education session with monthly phone follow-ups). Levels of eligibility, consent, adherence and retention were used as indicators of study feasibility. Primary outcomes were change from baseline to six months in venous disease-specific quality of life (as measured using the Venous Insufficiency Epidemiological and Economic Study Quality of Life [VEINES-QOL] questionnaire) and severity of post-thrombotic syndrome (as measured by scores on the Villalta scale) in the exercise training group versus the control group, assessed by t tests. Secondary outcomes were change in generic quality of life (as measured using the Short-Form Health Survey-36 [SF-36] questionnaire), category of severity of post-thrombotic syndrome, leg strength, leg flexibility and time on treadmill. Results Of 95 patients with post-thrombotic syndrome, 69 were eligible, 43 consented and were randomized, and 39 completed the study. Exercise training was associated with improvement in VEINES-QOL scores (exercise training mean change 6.0, standard deviation [SD] 5.1 v. control mean change 1.4, SD 7.2; difference 4.6, 95% CI 0.54 to 8.7; p = 0.027) and improvement in scores on the Villalta scale (exercise training mean change −3.6, SD 3.7 v. control mean change −1.6, SD 4.3; difference −2.0, 95% CI −4.6 to 0.6; p = 0.14). Most secondary outcomes also showed greater improvement in the exercise training group. Interpretation Exercise training may improve post

    Atypical motor behaviors are common among children with Autism Spectrum Disorders (ASD). However, little is known about onset and functional implications of differences in early motor development among infants later diagnosed with ASD. Two prospective experiments were conducted to investigate motor skills among six-month-olds at increased risk (high-risk) for ASD (N1 = 129; N2 = 46). Infants were assessed using the Mullen Scales of Early Learning (MSEL) and during toy play. Across both experiments, high-risk infants exhibited less mature object manipulation in a highly structured (MSEL) context and reduced grasping activity in an unstructured (free play) context than infants with no family history of ASD. Longitudinal assessments suggest that between six and ten months, grasping activity increases in high-risk infants. PMID:24978128

    Full Text Available We describe a new arachnophobia therapy that is specially suited for those individuals with severe arachnophobia who are reluctant to undergo direct or even virtual exposure treatments. In this therapy, patients attend a computer presentation of images that, while not being spiders, have a subset of the characteristics of spiders. The Atomium of Brussels is an example of such an image. The treatment group (n=13 exhibited a significant improvement (time × group interaction: P=.0026 when compared to the placebo group (n=12 in a repeated measures multivariate ANOVA. A k-means clustering algorithm revealed that, after 4 weeks of treatment, 42% of the patients moved from the arachnophobic to the nonarachnophobic cluster. Six months after concluding the treatment, a follow-up study showed a substantial consolidation of the recovery process where 92% of the arachnophobic patients moved to the nonarachnophobic cluster.

    Full Text Available The present study explored the conversion rate in individuals with Attenuated Psychosis Syndrome (APS and potential predictor for transition in China. Sixty-three participants were identified as APS were followed up six months later. The results showed that 17% of individuals with APS converted to psychosis. The converters exhibited poorer emotional experience and expression than the non-converters at baseline. A further binary logistic regression analysis showed that emotional experience could predict the transition (Wald = 4.18, p = 0.041, 95% CI = 1.04~6.82. The current study suggested an important role of emotional processing in the prediction of the development of full-blown psychosis.

    Full Text Available Abstract Objective: To evaluate the correlation between hemoglobin levels of mothers and their children on exclusive breastfeeding in the first six months of life. Methods: Cross-sectional study with 221 binomials (mother-child enrolled in a breastfeeding support program, who were stratified into six groups according to the children's age group. The sample consisted of children born at term with normal weight, with no neonatal complications and whose mothers did not have anemia or infectious disease at the time of data collection. Interviews were carried out with the mothers, blood was collected by peripheral venipuncture from mothers and children, and children's anthropometric data were assessed. Pearson's correlation coefficients between the hemoglobin levels of mothers and children were calculated. Six multiple linear regression models were adjusted with regression coefficient estimates, considering as statistically significant associations with p ≤ 0.05. Results: The correlation coefficients of hemoglobin levels of mothers and children ranged from 0.253, at three months, to 0.601, at five months. The hemoglobin level of mothers was correlated with the hemoglobin level of their children at four months (r = 0.578 and at five months (r = 0.601. In the adjusted multiple linear regression, the regression coefficients were higher at four months (β = 1.134; p = 0.002 and at five months (β = 0.845; p < 0.001. Conclusion: These findings allow for the conclusion that there is a correlation between the hemoglobin of mothers and the hemoglobin of their children on exclusive breastfeeding in the first six months of life.

    Treatments offered at the Maharishi Ayurveda Health Centre in Norway are based on Maharishi Vedic medicine, which is also known as Maharishi Ayurveda. It is a consciousness based revival of the ancient Ayurvedic medicine tradition in India and is established by Maharishi Mahesh Yogi, the founder of the Transcendental Meditation (TM) technique. To conduct a pilot study of the effect of the treatment program at the Health Centre on fibromyalgia patients. Thirty-one women with diagnosed fibromyalgia received an individually designed Maharishi Vedic physiological purification therapy. All subjects received personal advice on diet based on Ayurvedic principles, including a novel approach to food into-lerance, and daily routines. In addition they were offered instruction in TM (for stress and pain management and personal development) (four subjects started), and recommended Ayurvedic herbal food products for home treatment. A modified Fibromyalgia Impact Questionnaire included a visual analogue scale for each of the seven outcomes: working ability, generalised pain, tiredness, stiffness, tiredness on arising, anxiety and depression. Pre-treatment scores were compared with scores at six-month follow-up for levels of statistical significance. Twenty-eight subjects (90%) completed the follow-up. The outcome measures were reduced by 25 to 46% by the study's endpoint: working ability (pmeditating control group the TM-subgroup showed statistically significant improvements for all outcome measures except depression. In this pilot study fibromyalgia patients undergoing treatment at Maharishi Ayurveda Health Centre in Norway showed significant improvements six months post treatment. Because fibromyalgia is considered a treatment-resistant condition, these encouraging results warrant further research.

    Toxic organochlorine compounds (OC) are transmitted from mother to infant during lactation. OC are ingested by and stored in their offspring. Different harmful effects later in life have been attributed to the body pollution with these OC, although these findings are still discussed in an argumentative manner, since first other investigators could demonstrate beneficial effects of breast-feeding despite elevated OC concentrations, and second the benefits of breast-feeding are an unchallenged fact, especially in those countries, where infant formulas are not available. It was the aim of the present study to determine the lactational uptake of different OC (polychlorinated biphenyls (PCB), hexachlorobenzene (HCB), and DDE) in breast-fed vs. bottle-fed infants up to six months of age. With the written informed consent of the parents, blood samples were taken from each ten breast-fed and bottle-fed infants, respectively. The specimens were immediately centrifuged, and serum was stored in glass tubes without an anticoagulant up to analysis. Three higher-chlorinated PCB congeners (IUPAC Nos. 138, 153, and 180), HCB, and DDE, the main metabolite of DDT in mammals, were determined with capillary gas chromatography with electron capture detection. In addition, reliability was tested with gas chromatography-mass spectrometry. Possible correlations of OC with personal data were tested with a standard multivariate regression model. Differences between study groups were tested on mean differences with Wilcoxons test for independent samples. We could demonstrate that breast-fed infants have significantly (p<0.0001) elevated serum concentrations of all OC as early as at the age of six weeks (90%), which over and above nearly doubled further until the age of six months. (Median (μg/L); A=six weeks; B=six months): PCB 138, A: 0.40 vs. 0.09; B: 0.72 vs. 0.07; PCB 153, A: 0.57 vs. 0.11; B: 0.99 vs. 0.09; PCB 180, A: 0.33 vs. 0.04; B: 0.58 vs. 0.02; PCB (sum of the three PCB

    Low participation in health promotion programs (HPPs) might hamper their effectiveness. A potential reason for low participation is disagreement between needs and preferences of potential participants and the actual HPPs offered. This study aimed to investigate employees' need and preferences for HPPs, whether these are matched by what their employers provide, and whether a higher agreement enhanced participation. Employees of two organizations participated in a six-month follow-up study (n = 738). At baseline, information was collected on employees' needs and preferences for the topic of the HPP (i.e. physical activity, healthy nutrition, smoking cessation, stress management, general health), whether they favored a HPP via their employer or at their own discretion, and their preferred HPP regarding three components with each two alternatives: mode of delivery (individual vs. group), intensity (single vs. multiple meetings), and content (assignments vs. information). Participation in HPPs was assessed at six-month follow-up. In consultation with occupational health managers (n = 2), information was gathered on the HPPs the employers provided. The level of agreement between preferred and provided HPPs was calculated (range: 0-1) and its influence on participation was studied using logistic regression analyses. Most employees reported needing a HPP addressing physical activity (55%) and most employees preferred HPPs organized via their employer. The mean level of agreement between the preferred and offered HPPs ranged from 0.71 for mode of delivery to 0.84 for intensity, and was 0.47 for all three HPP components within a topic combined. Employees with a higher agreement on mode of delivery (OR: 1.72, 95% CI: 0.87-3.39) and all HPP components combined (OR: 2.36, 95% CI: 0.68-8.17) seemed to be more likely to participate in HPPs, but due to low participation these associations were not statistically significant. HPPs aimed at physical activity were most needed by

    To elucidate the association between vitamin D status, C-reactive protein (CRP) and fibrinogen. Secondary analysis of a randomised double-blind placebo controlled trial. Four longterm care hospitals (1215 beds) in Helsinki, Finland. 218 long-term inpatients aged over 65 years. Eligible patients (n = 218) were randomized to receive 0 IU/d, 400 IU/d, or 1200 IU/d cholecalciferol for six months. Plasma 25-hydroxyvitamin D (25-OHD), parathyroid hormone (PTH), high sensitive CRP, fibrinogen, amino-terminal propeptide of type I procollagen (PINP), and carboxy-terminal telopeptide of type I collagen (ICTP) were measured. The patients were aged (84.5 +/- 7.5 years), vitamin D deficient (25-OHD = 23 +/- 10 nmol/l), chronically bedridden and in stable general condition. The mean baseline CRP and fibrinogen were 10.86 mg/l (0.12 mg/l - 125.00 mg/l) and 4,7 g/l (2.3 g/l - 8.6 g/l), respectively. CRP correlated with ICTP (r = 0.217, p = 0.001), but not with vitamin D status. Supplementation significantly increased 25-OHD concentrations, but the changes in CRP and fibrinogen were insignificant and inconsistent. The post-trial CRP concentrations (0.23 mg/l -138.00 mg/l) correlated with ICTP (r = 0.156, p bedridden older patients.

The aim of the present study is to investigate the association between them, to evaluate the PD frequency among chemical dependents inpatients, this comorbidity association with social and demographic characteristics, used drug of choice, its impact on clinical evolution until the moment of their committal, the frequency of relapse, self-help group – and psychotherapic adherence among SRD patients six months following committal. Methods A 101 inpatients sample of chemical dependents was enrolled in 2 hospitals. The following instruments were applied: a questionnaire for social and demographic characteristics identification and drug use pattern, some questions from the sixth version of the Addiction Severity Index (ASI-6, the SCID-II questionnaire and specific questions concerning psychotherapic and self-help groups participation, and medication use. Results From these 101 patients, 55.4% were diagnosed with PD, being avoidant (14.9%, borderline (11.9% and antisocial (8.9% the more frequent ones found. PD patients had an earlier crack use in life (p = 0.038 and had also more previous treatments than the ones without PD (p = 0.005. Borderline PD patients were less worried to substance use problem (p = 0.003. After 6-months follow-up, no statistical significance was found between patients with and without PD regarding drug use or treatment adherence. Conclusion A high PD diagnosis was found in drug use inpatients. Patients diagnosed with SRD and PD need the identification of this comorbidity and of their personality characteristics in order to plan a more comprehensive and effective treatment.

    Determine outcomes of cooled radiofrequency ablation (C-RFA) of the genicular nerves for treatment of chronic knee pain due to osteoarthritis (OA). Cross-sectional survey. Academic pain medicine center. Consecutive patients with knee OA and 50% or greater pain relief following genicular nerve blocks who underwent genicular nerve C-RFA. Survey administration six or more months after C-RFA. Pain numeric rating scale (NRS), Medication Quantification Scale III (MQSIII), Patient Global Impression of Change (PGIC), and total knee arthroplasty (TKA) data were collected. Logistic regression was used to identify factors that predicted treatment success. Thirty-three patients (52 discrete knees) met inclusion criteria. Thirty-five percent (95% confidence interval [CI] = 22-48) of procedures resulted in the combined outcome of 50% or greater reduction in NRS score, reduction of 3.4 or more points in MQSIII score, and PGIC score consistent with "very much improved/improved." Nineteen percent (95% CI = 10-33) of procedures resulted in complete pain relief. Greater duration of pain and greater than 80% pain relief from diagnostic blocks were identified as predictors of treatment success. The accuracy of the model was 0.88 (95% CI = 0.78-0.97, P  <   0.001). Genicular C-RFA demonstrated a success rate of 35% based on a robust combination of outcome measures, and 19% of procedures resulted in complete relief of pain at a minimum of six months of follow-up. Report of 80% or greater relief from diagnostic blocks and duration of pain of less than five years are associated with high accuracy in predicting treatment success. Further prospective study is needed to optimize the patient selection protocol and success rate of this procedure. © 2017 American Academy of Pain Medicine. All rights reserved.

    Depressive disorder was associated with dysfunctional self-regulation. The current study attempted to design and test a comprehensive self-control training (CSCT) program with an overall emphasis on behaviral activation in depressed Chinese college students. Participants included 74 students who had diagnosed with major depression, they were randomly assigned to one of the two groups: intervention group (n=37), and control group (n=37). The intervention participants received an eight-week CSCT and four-month follow-up consolidation program, as compared to the control group who received only pre-post-and-follow-up measurements. All participants measured Beck Depression Inventory (BDI-Ⅱ) and Self-control Scale (SCS) at three time points: baseline, post-training, and four-month follow-up. The dropout rates were 6 (8.1%) in the intervention group and 3 (4.1%) in the control group at the end of six-month intervention. The general linear model repeated measures analysis of variance revealed that comparing with the control group, the intervention group participants had more increase in their trait self-control score, at the meantime, their depressive symptoms had significantly improved. Univariate and logistic regression analyses revealed that participants with milder baseline depressive symptoms were more likely to benefit from CSCT interventions; depression improvement was also associated with the number of sessions attended. The main limitation was related to the small sample size which consisted of college students who were relatively young and well educated. The current study demonstrates that CSCT program could temporarily enhance self-control capacity as well as improve depressive symptoms; participants who are mildly to moderately depressed, and who could adhere to the training protocol are more likely to benefit from the intervention.

    The purpose of the project was to provide a reference for radiographic anatomy of the developing equine foredigit and metacarpophalangeal region. Using xeroradiographic techniques, both foredigits and meta-carpophalangeal regions of six Quarter Horse foals were radiographed at one day of age and at two-week intervals until the foals were six weeks old. The foals were then radiographed at four-week intervals until they were 12 months old. This report deals specifically with the first six months of postnatal development. Lateromedial and dorsopalmar xeroradiographs of each foredigit and metacarpophalangeal region and a dorsal 65° proximal-palmarodistal oblique view of the distal part of the digit were made for each examination. The foals were weighed and measured at the withers immediately prior to each examination. Representative xeroradiographs were selected and appropriately labeled to demonstrate normal radio-graphic anatomy of these regions. First radiographic appearance of distal epiphyseal ossification in metacarpal 2 and metacarpal 4 was extremely variable and ranged from four to 38 weeks. Radiographic closure of the proximal physis of the middle phalanx ranged from 18 to 30 weeks (mean = 26 weeks). Radiographic closure of the proximal physis of the proximal phalanx ranged from 22 to 38 weeks (mean = 30 weeks). Radiographic closure of the distal physis of metacarpal 3 ranged from 18 to 38 weeks (mean = 29 weeks). When xeroradiographic physeal closure times were compared with scintigraphic closure times from a companion study, results correlated very well. A crena marginis solearis was observed in ten of 12 forelimbs (83.3%); its first radiographic appearance ranged from four to 22 weeks (mean = 11–12 weeks). A consistent groove in the hoof wall, which formed near the time of birth and moved distally at about 3 mm per week, was noted. The groove's distance from the proximal hoof border may be useful in age estimation of foals less than 18–20 weeks old

    Objectives To evaluate the durability of effects of a computer assisted version of cognitive behavioral therapy (CBT) as treatment for substance dependence through a 6 month follow-up. Methods Following a randomized clinical trial in which 73 individuals seeking outpatient treatment for substance dependence in an outpatient community setting were randomized to either standard treatment-as-usual (TAU) or TAU with 8 weeks of biweekly access to computer-based training for CBT (CBT4CBT), participants were interviewed one, three, and six months after the termination of study treatments. Results Sixty of the 73 participants were reached for follow-up (82%); follow up rates and availability of data were comparable across treatment conditions. Random regression analyses of use across time indicated significant differences between groups, such that those assigned to TAU increased their drug use across time while those assigned to CBT4CBT tended to improve slightly. The durability of the CBT4CBT effect remained even after controlling for treatment retention, treatment substance use outcomes, and exposure to other treatment during the follow-up period. Conclusions Computerized CBT4CBT appears to have both short-term and enduring effects on drug use. PMID:19041197

    Full Text Available Newborns are rapidly colonized by microbes and their intestinal tracts contain highly dynamic and rapidly developing microbial communities in the first months of life. In this study, we describe the feasibility of isolating mRNA from rapidly processed faecal samples and applying deep RNA-Seq analysis to provide insight into the active contributors of the microbial community in early life. Specific attention is given to the impact of removing rRNA from the mRNA on the phylogenetic and transcriptional profiling and its analysis depth. A breastfed baby was followed in the first six months of life during adaptation to solid food, dairy products, and formula. It was found that, in the weaning period, the total transcriptional activity of Actinobacteria, mainly represented by Bifidobacterium, decreased while that of Firmicutes increased over time. Moreover, Firmicutes and Actinobacteria, including the canonical Bifidobacteria as well as Collinsella, were found to be important contributors to carbohydrate fermentation and vitamin biosynthesis in the infant intestine. Finally, the expression of Lactobacillus rhamnosus-like genes was detected, likely following transfer from the mother who consumed L. rhamnosus GG. The study indicates that metatranscriptome analysis of the infant gut microbiota is feasible on infant stool samples and can be used to provide insight into the core activities of the developing community.

    A pseudo-normalization of infarcted brain parenchyma, similar to the ''fogging effect'' which usually occurs after 2-3 weeks, can be observed on CT performed immediately after endovascular stroke treatment (EST). Goal of this study was to analyze the incidence of this phenomenon and its evolution on follow-up imaging. One hundred fifty-two patients in our database of 949 patients, who were treated for acute stroke between January 2010 and January 2015, fulfilled the inclusion criteria of (a) EST for an acute stroke in the anterior circulation, (b) an ASPECT-score < 10 on pre-interventional CT, and (c) postinterventional CT imaging within 4.5 h after the procedure. Two independent reviewers analyzed imaging data of these patients. Transformation of brain areas from hypoattenuated on pre-interventional CT to isodense on postinterventional CT was seen in 37 patients in a total of 49 ASPECTS areas (Cohen's kappa 0.819; p < 0.001). In 17 patients, the previously hypoattenuated brain areas became isodense, but appeared swollen. In 20 patients (13%), the previously hypodense brain area could not be distinguished from normal brain parenchyma. On follow-up imaging, all isodense brain areas showed signs of infarction. Pseudo-normalization of infarct hypoattenuation on postinterventional CT is not infrequent. It is most likely caused by contrast leakage in infarcted parenchyma and does not represent salvage of ischemic brain parenchyma. (orig.)

    Full Text Available Abstract Background A fever is an increase in the body's temperature above normal. This study examined how US pediatricians perceive and manage fever generally versus fever occurring after vaccination in infants up to six months of age. Methods A web-based survey of 400 US pediatricians subscribing to the Physician Desk Reference was conducted in December 2008. Data were collected on the respondents' socio-demographics, number of years in practice, type of practice, their definition of fever severity in infants, and their recommendations for managing fever. Generalized Estimating Equations were used to estimate the odds of a pediatrician recommending an emergency room visit (ER or a hospital admission, office visits, or other treatment option, as a function of infant's age, temperature, whether the infant has recently received a vaccine, and whether the fever was reported during or after office hours, adjusting for practice type and socio-demographic variables. Results On average, the 400 responding pediatricians' (64% were female, average age of 49 years, years in practice = 20 years threshold for extremely serious fever was ≥39.5°C and ≥ 40.0°C for infants 0-2 month and >2-6 month of age respectively. Infants were more likely to be referred to an ER or hospital admission if they were ≤ 2 months of age (Odds Ratio [OR], 29.13; 95% Confidence interval [95% CI], 23.69-35.82 or >2-4 months old (OR 3.37; 95% CI 2.99-3.81 versus > 4 to 6 months old or if they had a temperature ≥ 40.0°C (OR 21.06; 95% CI 17.20-25.79 versus a temperature of 38.0-38.5°C. Fever after vaccination (OR 0.29; 95% CI 0.25-0.33 or reported during office hours (OR 0.17; 95% CI 0.15-0.20 were less likely to result in referral to ER or hospital admission. Conclusion Within this sample of US pediatricians, perception of the severity of fever in infants, as well as the response to infant fever are likely to depend on the infant's age. Recommendations for the management

    To explore somatic conditions in a sample of 2299 child and adolescent survivors of an earthquake and their relationship to posttraumatic stress disorder (PTSD) symptoms. The Children's Revised Impact of Event Scale, the Patient Health Questionnaire (PHQ)-13 scale, a short version of PHQ-15 scale that omits two items involving sexual pain/problems and menstrual problems, and a project-developed questionnaire were administered to participants three and six months after the earthquake. Among child and adolescent survivors, the prevalence rates of probable PTSD were 37.4 and 24.2% three and six months, respectively, after the earthquake. The most common somatic symptoms were trouble sleeping (58.4 and 48.4%), feeling tired or having low energy (52.0 and 46.1%), and stomach pain (45.8 and 45.4%) after three and six months, respectively. Several specific somatic symptoms evaluated three months after the earthquake including trouble sleeping, headache, and shortness of breath were predictors of the overall PTSD symptoms evaluated six months after the earthquake. Additionally, the symptom of hyperarousal evaluated after three months could predict the overall somatic symptoms evaluated after six months. PTSD and somatic symptoms were common after the earthquake, and a longitudinal association between PTSD and somatic symptoms was detected among child and adolescent survivors. These findings have implications in China and possibly elsewhere. Copyright © 2015 Elsevier Inc. All rights reserved.

  6. Independent development of the Reach and the Grasp in spontaneous self-touching by human infants in the first six months

    Directory of Open Access Journals (Sweden)

    Full Text Available The Dual Visuomotor Channel Theory proposes that visually guided reaching is a composite of two movements, a Reach that advances the hand to contact the target and a Grasp that shapes the digits for target purchase. The theory is supported by biometric analyses of adult reaching, evolutionary contrasts, and differential developmental patterns for the Reach and the Grasp in visually guided reaching in human infants. The present ethological study asked whether there is evidence for a dissociated development for the Reach and the Grasp in nonvisual hand use in very early infancy. The study documents a rich array of spontaneous self-touching behavior in infants during the first six months of life and subjects the movements to analyses of body target, contact type, and Grasp. Video recordings were made of resting alert infants biweekly from birth to 6 months. In younger infants, self-touching targets included the head and trunk. As infants aged, targets became more caudal including the hips, legs, and feet. In younger infants hand contact was mainly made with the dorsum of the hand, but as infants aged contacts included palmar and eventually grasp and manipulatory contacts with the body and clothes. The relative incidence of caudal contacts and palmar contacts increased concurrently and were significantly correlated throughout the period of study. In contrast, developmental increases in self grasping emerged a few weeks after the increases observed in caudal and palmar contacts. The behavioral and temporal pattern of these spontaneous self-touching movements suggest that the Reach, in which the hand extends to make a palmar self-contact, and the Grasp, in which the digits close and make manipulatory movements, have partially independent developmental profiles. The results additionally suggest that self-touching behavior is an important developmental phase that allows for the coordination of the Reach and the Grasp prior to their use under visual

    Short-term use of sodium bicarbonate (NaHCO3)-containing toothpaste reduces plaque and improves clinical measures of gingivitis. To examine this over a longer period, we compared efficacy and tolerability of twice-daily brushing for 24 weeks with 67% or 0% NaHCO3-containing toothpastes in USA-based participants with moderate gingivitis (Clinicaltrials.gov:NCT02207400). This was a six-month, randomized, examiner-blind, parallel-group, clinical trial. Investigators randomized adults with blood in expectorate after brushing and ≥ 20 gingival bleeding sites to 67% NaHCO3 (n = 123; n = 107 completed study) or 0% NaHCO3 (n = 123; n = 109 completed study) toothpastes. Primary efficacy variables included between-treatment differences in number of bleeding sites and Modified Gingival Index (MGI) score at 24 weeks. Secondary efficacy variables included Bleeding Index and Turesky modification of the Quigley-Hein Plaque Index (overall and interproximal sites) at six, 12, and 24 weeks. A subset of 50 participants underwent sampling to assess plaque microbiology over the course of treatment. Compared with the 0% NaHCO3 toothpaste, the 67% NaHCO3 toothpaste produced statistically significant improvements at Week 24 in number of bleeding sites (46.7% difference) and MGI (33.9% difference), and for all other endpoints (all p < 0.0001). There was no significant between-treatment difference in the proportion of participants harboring opportunistic pathogens. Products were generally well tolerated, with two and five treatment-related adverse events reported in the 67% and 0% NaHCO3 toothpaste groups, respectively. Gingival bleeding, gingivitis, and plaque indices were significantly improved at six, 12, and 24 weeks with twice-daily brushing with 67% NaHCO3-containing toothpaste in participants with moderate gingivitis.

    The aim of this study was to compare the performance of polytetrafluoroethylene (PTFE) grafts with luminal coating of immobilized heparin to that of standard PTFE grafts at six months. Twenty-eight common carotid arteries in fourteen sheep were bypassed with heparin-coated PTFE grafts (6 mm diameter, 6 cm length) on one side and standard PTFE grafts on the other. The grafts were explanted after six months. The thickness of intimal hyperplasia (IH) in open grafts was measured with histomorphometrical methods. Two of 14 heparinized PTFE grafts and nine of 14 grafts in the control PTFE-group were occluded at explantation (P=0.006). Six-month patency rates for heparinized PTFE grafts and for standard PTFE grafts were 86% and 36%, respectively. Mean graft anastomotic IH thickness in open grafts were 0.074 mm for heparinized PTFE grafts and 0.259 mm for PTFE-grafts (P=0.006). PTFE grafts with luminal coating containing immobilized heparin had significantly better patency and recruited less intimal hyperplasia than standard PTFE grafts at six months.

    The aim was to investigate dentin bond strength of two resin-ceramic materials and five cements after 24 h and six months storage. Cylinders (n=15/group) of Lava Ultimate (3M ESPE) and VITA ENAMIC (VITA Zahnfabrik) were cemented to mid-coronal dentin of 300 extracted human molars with RelyX Ultimate (3M ESPE), PANAVIA F2.0 (Kuraray), Variolink II (Ivoclar Vivadent), els cem (Saremco Dental), or Ketac Cem Plus (3M ESPE). Shear bond strength (SBS) was measured after 24 h or six months storage (37°C, 100% humidity) and statistically analyzed (significance level: α=0.05). SBS varied markedly between Lava Ultimate and VITA ENAMIC, between the five cements, and between storage of either 24 h or six months. After six months, SBS was highest when Lava Ultimate was cemented with RelyX Ultimate and when VITA ENAMIC was cemented with RelyX Ultimate or with Variolink II. Lava Ultimate was somewhat more sensitive to storage than was VITA ENAMIC.

    What is the incidence of contractures six months after stroke? Can factors measured within four weeks of stroke predict the development of elbow, wrist, and ankle contractures six months later? Prospective cohort study. Consecutive sample of 200 adults with stroke admitted to a Sydney hospital. Loss of range of motion in major joints of the body was measured using a 4-point ordinal contracture scale. In addition, elbow extension, wrist extension, and ankle dorsiflexion range of motion were measured using torque-controlled procedures. Potential predictors of contracture were age, pre-morbid function, severity of stroke, muscle strength, spasticity, motor function, and pain. Measurements were obtained within four weeks of stroke and at six months after stroke. 52% of participants developed at least one contracture. Incidence of contracture varied across joints from 12% to 28%; shoulders and hips were most commonly affected. Muscle strength was a significant predictor of elbow, wrist, and ankle joint range. Prediction models explained only 6% to 20% of variance in elbow, wrist, and ankle joint range. About half of all patients with stroke develop at least one contracture within six months of stroke. Incidence of contractures across all joints ranged from 12% to 28%. Muscle strength is a significant predictor of elbow, wrist, and ankle contractures but cannot be used to accurately predict contractures in these joints.

    To evaluate the caries risk based on the salivary levels of streptococcus mutans in children of 6-12 years of age group before and after consuming probiotic ice-cream containing Bifidobacterium lactis Bb-12 and Lactobacillus acidophilus La-5. A double blind, placebo controlled trial was carried out in 60 children aged between 6 to 12 years with zero decayed, missing, and filled teeth (DMFT). They were randomly divided into two equal groups. Saliva sample were collected before the consumption of ice-cream and Streptococcus mutans count was calculated and recorded as baseline data. For the next seven days both the groups were given ice creams marked as A and B. Saliva samples were collected after ice-cream consumption at the end of study period and also after a washout period of 30 days and again after six months. Samples were inoculated and colonies were counted. On statistical evaluation by students paired t-test, probiotic ice-cream brought significant reduction in the Streptococcus mutans count after seven days of ice-cream ingestion (pice-cream consumption. After six months of the study period in both the groups the salivary levels of Streptococcus mutans was similar to the baseline. Probiotic ice-cream containing Bifidobacterium lactis Bb-12 and Lactobacillus acidophilus La-5 can cause reduction in caries causative organism. The dosage of the probiotic organisms for the long term or synergetic effect on the oral health are still needed to be explored.

    Full Text Available A comparison study of the Web interaction evolution of a group of people with intellectual disabilities, when performing search tasks using the YouTube platform, is presented. For the effect, we compare results in two assessment moments (the second assessment moment was performed, within the 6 months after the first one. We aimed at evaluating the evolution of their digital skills by comparing two assessment moments through the following usability variables: effectiveness, we register the rate of successful complete conclusion of Web search activities using the YouTube; efficiency, where it was register: time of task conclusion, number and type of difficulties found and errors made; satisfaction, the rate of acceptance and comfort when performing the tasks; and, autonomy indicators. The results revealed that participants depicted more learning skills when performing the second assessment moment, which is indicated by the number of participants who were able to conclude the activities and it's also confirmed by the prominent results of the second assessment moment. When it comes to errors, they made more errors in the first assessment moment in general. While handling the input devices the participants had a better performance with the mouse than the keyboard however in the second assessment moment they improved their skills with the mouse and keyboard input device. However, we believed that the keyboard will never be a device that they can be autonomous with due to their reading/ writing difficulties, which itself represents a didactic challenge when it comes to the very presentation of appropriate methodologies and techniques that may help them overcome such problem. Overall, users with intellectual disabilities had a good experience with the YouTube interface because they were motivated and satisfied during the execution of the tasks, however they were not autonomy with the search option.

    to examine the effect of pregnancy planning status in the concordance between intention to use and current use of contraceptives among postpartum women. a prospective study was conducted in 12 primary health care facilities in São Paulo, Brazil, from November 2013 to September 2014. A total of 264 woman aged 15-44 years old completed a face-to-face interview when they were pregnant (baseline), and were interviewed by phone at 6 months postpartum. At baseline, participants were questioned about the contraceptive method they would prefer to be using at 6 months postpartum. At 6 months postpartum, they answered about the contraceptive method they were currently using. Pregnancy planning status was measured using the Brazilian Portuguese London Measure of Unplanned Pregnancy. We conducted logistic regression, considering contraceptive preference-use concordance as the dependent variable and the main covariate as pregnancy planning status. Only 28.9% of postpartum women were using the method they preferred to use when they were pregnant. The agreement between preference and contraceptive use was higher for injectables (60.9%) and lowest for IUD, as nobody who preferred it was actually using it. Women who were not sure about what method they intended to use after childbirth more frequently reported no use at six months postpartum. Multivariate logistic regression showed that postpartum women whose pregnancy was unplanned were less likely to use the contraceptive methods that they intended to use when they were pregnant [aOR=0.36; 95%CI=0.14-0.97]. Brazilian women were able to access contraceptives in the postpartum period. However, there is a considerable discordance between their contraceptive intention to use and use at the sixth postpartum month. A higher unmet demand for IUD and sterilization should be highlighted. The pregnancy planning status is associated to postpartum contraceptive preference-use concordance, so interventions before pregnancy may affect

    The changes in cooking quality and phenolic composition of whole black and red rice grains stored during six months at different temperatures were evaluated. Brown rice with known cooking quality properties and low phenolic levels was used for purposes comparison. All rice genotypes were stored at 13% moisture content at temperatures of 16, 24, 32, and 40°C. Cooking time, hardness, free and bound phenolics, anthocyanins, proanthocyanidins, and free radical scavenging capacity were analysed. The traditional rice with brown pericarp exhibited an increase in cooking time and free phenolics content, while rice with black pericarp exhibited a reduction in cooking time after six months of storage at the highest studied temperature of 40°C. There as increases in ferulic acid levels occurred as a function of storage temperature. Red pericarp rice grains showed decreased antioxidant capacity against ABTS radical for the soluble phenolic fraction with increased time and storage temperature. Copyright © 2017 Elsevier Ltd.

    In the setting of a six-month, open-label clinical trial, 141 consecutively enrolled, hypertensive, overweight patients were randomized to the oral ingestion of psyllium powder or guar gum 3.5 gr t.i.d., to be taken 20 min before the main two meals, or to standard diet. Both fibers improved significantly BMI, FPG, FPI, HOMA Index, HbA1c, LDL-C, and ApoB. Psyllium supplementation only exerted a significant improvement in plasma TG concentration, in SBP and DBP. In our study, six-month supplementation with psyllium fiber, but not with guar fiber nor standard diet, appears to significantly reduce both SBP and DBP in hypertensive overweight subjects.

    Objectives To evaluate the impact of implementing a simple, user-friendly eLearning module on hand hygiene (HH) compliance and infection rates. Design Preintervention and postintervention observational study. Participants All neonates admitted to the neonatal intensive care unit (NICU) over the study period were eligible for participation and were included in the analyses. A total of 3422 patients were admitted over a 36-month span (July 2009 to June 2012). Interventions In the preintervention and postintervention periods (phases I and II), all healthcare providers were trained on HH practices using an eLearning module. The principles of the ‘4 moments of HH’ and definition of ‘baby space’ were incorporated using interactive tools. The intervention then extended into a long-term sustainability programme (phase III), including the requirement of an annual recertification of the module and introduction of posters and screensavers throughout the NICU. Primary and secondary outcome measures The primary outcome was HH compliance rates among healthcare providers in the three phases. The secondary outcome was healthcare-associated infection rates in the NICU. Results HH compliance rates declined initially in phase II then improved in phase III with the addition of a long-term sustainability programme (76%, 67% and 76% in phases I, II and III, respectively (pchallenging to implement and sustain with the need for ongoing reinforcement and education.

    Evaluation of impairment and disability in stroke patients with a severe cortical infarction at admission as well as six months after the stroke. Prospective and descriptive study. Rehabilitation Centre Heliomare, Wijk aan Zee, the Netherlands. Between 1 January 1987 en 31 May 1992 stroke patients were admitted to the rehabilitation centre with a severe, first ever, cortical infarction without any comorbidity. The patients were dependent in activities of daily living and wheel-chair-bound. Motor and neuropsychological impairment and disability were evaluated at admission to the rehabilitation centre as well as six months after the stroke. Return to home and length of stay were evaluated. 43 patients were included. Recovery of arm and hand function was very poor (there was complete paresis at admission in 33 patients (77%) and six months after the CVA in 25 patients (58%)); recovery of the affected leg was reasonable (complete paresis in 10 (23%) and 0 patients, respectively). Cognitive deficits diminished in severity, but remained noticeable in three-quarters of the patients. Independent walking was achieved by 30 patients (70%), independence in personal activities of daily living by 32 patients (74%) and returning home by 36 patients (84%). The mean hospital stay was 26 weeks (SD: 9.26; range: 11-30). Prognosis of personal independence and returning home after a severe cortical infarction was rather good despite poor recovery of motor and cognitive impairment.

    Full Text Available OBJECTIVE: To analyze adherence to the recommended iron, zinc and multivitamin supplementation guidelines for preemies, the factors associated with this adherence, and the influence of adherence on the occurrence of anemia and iron, zinc and vitamin A deficiencies. METHODS: This prospective cohort study followed 58 preemies born in 2014 until they reached six months corrected age. The preemies were followed at a referral secondary health service and represented 63.7% of the preterm infants born that year. Outcomes of interest included high or low adherence to iron, zinc and multivitamin supplementation guidelines; prevalence of anemia; and prevalences of iron, zinc, and vitamin A deficiencies. The prevalence ratios were calculated by Poisson regression. RESULTS: Thirty-eight (65.5% preemies presented high adherence to micronutrient supplementation guidelines. At six months of corrected age, no preemie had vitamin A deficiency. The prevalences of anemia, iron deficiency and zinc deficiency were higher in the low-adherence group but also concerning in the high-adherence group. Preemies with low adherence to micronutrient supplementation guidelines were 2.5 times more likely to develop anemia and 3.1 times more likely to develop zinc deficiency. Low maternal education level increased the likelihood of nonadherence to all three supplements by 2.2 times. CONCLUSIONS: Low maternal education level was independently associated with low adherence to iron, zinc and vitamin A supplementation guidelines in preemies, which impacted the prevalences of anemia and iron and zinc deficiencies at six months of corrected age.

    Full Text Available All football teams that compete within the F. A. Premier League possess an academy, whose objective is to produce more and better home-grown players that are capable of playing professionally. These young players spend a large amount of time with their coach, but little is known about player’s perception of the coach–athlete relationship within F. A. Premier League Academies. The objectives of this study were to examine whether perceptions of the coach–athlete relationship changed over six months and if the coach–athlete relationship predicted self-reported goal achievement among F. A. Premier League academy players. This study included cross-sectional (n = 104 and longitudinal (n = 52 assessments, in which academy soccer players completed a measure of the coach–athlete relationship and goal achievement across either one or two time periods. The cross-sectional data were subjected to bivariate correlations, whereas the longitudinal data were analyzed using multiple regressions. Perceptions of the coach–athlete relationship remained stable over time. The coach–athlete relationship predicted the achievement of mastery goals six months later. Enhancing the quality of the coach–athlete relationship among elite adolescent athletes appears to be a suitable way of maximizing mastery achievement goals, particularly among developmental athletes who participate in team sports.

    Treating binge eating disorders is not easy: the disordered eating is usually combined with a patient who is overweight and often obese. As underlined by the current literature, treatment outcome must focus, at a minimum, on the binge eating characterizing this disorder, on weight changes, and preferably also changes in co-morbid psychopathology. To address these issues, cognitive behavioral therapy (CBT) is still considered the best approach. However, if we check the results of follow-up studies, different authors reported some relapse in the frequency of binge eating and small weight gains over the follow-up period. This paper describes the 6-month follow-up outcome of the Experiential Cognitive Therapy (ECT), a multi factorial treatment for binge eating disorders, including virtual reality therapy. These results are compared in a randomized controlled trial (n = 36) with the ones obtained by CBT and nutritional groups only. The results showed that 77% of the ECT group quit binging after 6 months versus 56% for the CBT sample and 22% for the nutritional group sample. Moreover, the ECT sample reported better scores in most psychometric tests including EDI-2 and body image scores.

    In 2015, a program was initiated to carefully track and monitor the growth of the solar industry in SC. Prior to then, little information was available on the costs associated with distributed photovoltaic (PV) installations in the Southeastern US. For this report, data were collected from businesses on the number of hires they had at the end of 2014 and compared with data for 2015 and June 2016. It was found that the percentage of installers within the state who serve the residential sector increased to 82% from 67%. During the same time period, the average size of initiated installations for residential, commercial, and utility scale installations all trended upwards. Where residential installations were typically 5 kW-DC in 2014, they were typically 10 kW-DC by late 2015 and in mid-2016. For commercial installations, the average size grew from 84 kW-DC in 2014 to between 136-236 kW-DC in 2015 and then 188-248 kWDC in mid-2016. An exception was seen in utility scale installations where a 2.3 MW-DC system was common in 2014, the size grew to be 5-15 MW-DC in late 2015. The average size dropped 3.1-4.4 MWDC in mid-June 2016, though individual averages up to 20 MW-DC were reported.

    Full Text Available ABSTRACT INTRODUCTION: The use of flowable composites as an orthodontic bonding adhesive merits great attention because of their adequate bond strength, ease of clinical handling and reduced number of steps in bonding. OBJECTIVE: The aim of this Randomized Controlled Trial was to comparatively evaluate over a 6-month period the bond failure rate of a flowable composite (Heliosit Orthodontic, Ivoclar Vivadent AG, Schaan and a conventional orthodontic bonding adhesive (Transbond XT, 3M Unitek. METHODS: 53 consecutive patients (23 males and 30 females who fulfilled the inclusion and exclusion criteria were included in the study. A total of 891 brackets were analyzed, where 444 brackets were bonded using Heliosit Orthodontic and 447 brackets were bonded using Transbond XT. The survival rates of brackets were estimated with the Kaplan-Meier analysis. Bracket survival distributions for bonding adhesives, tooth location and dental arch were compared with the log-rank test. RESULTS: The failure rates of the Transbond XT and the Heliosit Orthodontic groups were 8.1% and 6% respectively. No significant differences in the survival rates were observed between them (p= 0.242. There was no statistically significant difference in the bond failure rates when the clinical performance of the maxillary versus the mandibular arches and the anterior versus the posterior segments were compared. CONCLUSIONS: Both systems had clinically acceptable bond failure rates and are adequate for orthodontic bonding needs.

    Sacroiliac (SI) joint pain is a prevalent, underdiagnosed cause of lower back pain. SI joint fusion can relieve pain and improve quality of life in patients who have failed nonoperative care. To date, no study has concurrently compared surgical and non-surgical treatments for chronic SI joint dysfunction. We conducted a prospective randomized controlled trial of 148 subjects with SI joint dysfunction due to degenerative sacroiliitis or sacroiliac joint disruptions who were assigned to either minimally invasive SI joint fusion with triangular titanium implants (N=102) or non-surgical management (NSM, n=46). SI joint pain scores, Oswestry Disability Index (ODI), Short-Form 36 (SF-36) and EuroQol-5D (EQ-5D) were collected at baseline and at 1, 3 and 6 months after treatment commencement. Six-month success rates, defined as the proportion of treated subjects with a 20-mm improvement in SI joint pain in the absence of severe device-related or neurologic SI joint-related adverse events or surgical revision, were compared using Bayesian methods. Subjects (mean age 51, 70% women) were highly debilitated at baseline (mean SI joint VAS pain score 82, mean ODI score 62). Six-month follow-up was obtained in 97.3%. By 6 months, success rates were 81.4% in the surgical group vs. 23.9% in the NSM group (difference of 56.6%, 95% posterior credible interval 41.4-70.0%, posterior probability of superiority >0.999). Clinically important (≥15 point) ODI improvement at 6 months occurred in 75% of surgery subjects vs. 27.3% of NSM subjects. At six months, quality of life improved more in the surgery group and satisfaction rates were high. The mean number of adverse events in the first six months was slightly higher in the surgical group compared to the non-surgical group (1.3 vs. 1.0 events per subject, p=0.1857). Six-month follow-up from this level 1 study showed that minimally invasive SI joint fusion using triangular titanium implants was more effective than non-surgical management

    Job anxiety is a severe problem in many patients with chronic mental disorders, as it usually results in specific participation problems in the workplace and long-term sick leave. The aim of this study was to explore the development of sick leave in dependence on general psychosomatic complaints and job anxiety from admission to a psychosomatic inpatient treatment until 6 months after discharge. A convenience sample of 91 patients, suffering from multiple mental disorders, filled in self-rating questionnaires on job anxiety (Job Anxiety Scale) and on general psychosomatic symptom load (Symptom Checklist-90-Revised) at the beginning, the end, and 6 months after discharge from an inpatient psychosomatic treatment. Additionally, sick leave status and employment status were assessed before and 6 months after the treatment. 15.4% of 91 patients were on sick leave before inpatient treatment and at follow-up (SS group), 20.9% were fit for work at intake and follow-up (FF group), 6.6% were fit for work initially and on sick leave later (FS group), and 57.1% on sick leave first and working at follow-up (SF group). In regard to general psychosomatic complaints, there were initially high scores on the SCL, a marked reduction during inpatient treatment, and a bouncing back to initial levels at follow-up for all 4 patient groups. SS and FS patients showed the highest scores at intake and follow-up. Concerning job anxiety, SS patients had the highest scores at all three assessments, while FF patients had significantly lower scores, with only low variation between assessments. SF patients started with comparatively high scores of job anxiety, which even increased before reentering work, but decreased in the follow-up period when they were confronted with work again. FS patients started low (like the FF patients) at intake, reduced their job anxiety further till discharge, but increased to higher scores at follow-up. General psychosomatic symptom load and job anxiety show a

    Recent studies suggest that risperidone long-acting injection (RLAI) may be considered for controlling mood episodes in bipolar disorder patients who have relapsed due to medication nonadherence or failure to respond to standard therapies. Currently, no study has reported the usefulness of RLAI in youths with bipolar disorder. The aim of this study was to evaluate short-term effects of RLAI in the naturalistic treatment of early-onset bipolar disorder and its role in symptomatic remission and adherence to treatment. Nineteen early-onset bipolar disorder outpatients receiving RLAI were observed in a 6-month naturalistic study at the outpatient clinic of the Child and Adolescent Affective Disorders Program at the Institute of Psychiatry of the University of São Paulo, São Paulo, Brazil. All patients met DSM-IV criteria for bipolar disorder. Clinical response to RLAI was evaluated using the Children's Global Assessment Scale (CGAS) and Clinical Global Impressions scale (CGI) across 3 time periods: index time (T0), 8 weeks after (T1), and 24 weeks after (T2). These subjects were recruited from May 2008 to December 2009. Patients receiving RLAI presented considerable improvement in global functioning (CGAS: T0 = 20.6; T1 = 42.9; and T2 = 49.2) and clinical severity (CGI: T0 = 5.9; T1 = 3.9; and T2 = 3.4). Global CGI mean scores of clinical improvement were 2.2 at T1 and 2.4 at T2. There were no significant changes in laboratory measurements and weight throughout follow-up. RLAI was shown to be an alternative treatment for youths with bipolar disorder failing to respond to prior medication trials or with adherence problems. Further blind, randomized controlled studies are necessary to confirm these initial findings.

    2017-01-01

    Full Text Available Objective. To evaluate the factor structure of Functional Independence Measure (FIM® scale amongst people with spinal cord injury (SCI. Methods. This was a retrospective, register-based cohort study on 155 rehabilitants with SCI. FIM was assessed at the beginning and at the end of multidisciplinary inpatient rehabilitation. The internal consistency of the FIM was assessed with Cronbach’s alpha and exploratory factor analysis was employed to approximate the construct structure of FIM. Results. The internal consistency demonstrated high Cronbach’s alpha of 0.95 to 0.96. For both pre- and postintervention assessments, the exploratory factor analysis resulted in 3-factor structures. Except for two items (“walking or using a wheelchair” and “expression”, the structures of the identified three factors remained the same from the beginning to the end of rehabilitation. The loadings of all items were sufficient, exceeding 0.3. Both pre- and postintervention chi-square tests showed significant p values < 0.0001. The “motor” domain was divided into two factors with this 2-factor structure enduring through the intervention period. Conclusions. Amongst rehabilitants with SCI, FIM failed to demonstrate unidimensionality. Instead, it showed a 3-factor structure that fluctuated only little depending on the timing of measurement. Additionally, when measured separately, also motor score was 2-dimensional, not 1-dimensional. Using a total or subscale FIM, scores seem to be unjustified in the studied population.

  7. The Post-Intervention Persistence of Energy Conservation Behaviors: An Evaluation of the ‘Start Green’ Program

    2018-03-01

    Full Text Available For more than four decades, behavioral intervention programs informed by psychology have been employed to increase pro-environmental behaviors. However, there has been little evidence for the post-intervention durability of target behaviors. The few studies that have conducted such evaluations have found that improvements often return to baseline levels post-intervention. This study evaluated the durability of home energy conservation behaviors before, during, and after a community based multi-technique intervention program, and examined the relationship between behavioral durability and the perceived importance, convenience and family norms of each behavior, as well as generalized pro-conservation decision making. The results show increased frequency in target behaviors that remain elevated seven months post-intervention. While the reported generalization of pro-conservation decision-making consistently increased during the study, perceived importance, convenience, and family norms of target conservation behaviors were largely unaffected. In addition, the few significant alterations in these perceptions were found to be due to increases during the post-intervention period only, indicating that they are not necessary pre-requisites for durable behavior change. These results show that a well designed community based intervention can have direct impacts on target behaviors that persist beyond its termination.

    Refractory angina pectoris (AP) is a persistent, painful condition characterized by angina caused by coronary insufficiency in the presence of coronary artery disease. It has been emphasized that there are possible underlying neuropathophysiological mechanisms for refractory AP but chronic ischemia is still considered to be the main problem. These patients suffer from severe AP and cannot be controlled by a combination of pharmacological therapies, angioplasty or coronary bypass surgery. AP has a negative impact on quality of life and daily life. Enhanced external counterpulsation (EECP) is a therapeutic option for these patients. The aim of this study was to evaluate EECP after six months regarding physical capacity and health-related quality of life (HRQoL) in patients with refractory AP. This was a study with single case research experimental design involving 34 patients treated with EECP. Six minute walk test (6MWT), functional class with Canadian Cardiological Society (CCS) classification and self-reported HRQoL questionnaires as Short Form 36 (SF-36) were collected at baseline and after treatment. CCS class and SF-36 were repeated at six months follow-up. Patients enhanced walk distance on average by 29 m after EECP (p<0.01). CCS class also improved (p<0.001) and persisted at six months follow-up (p<0.001). HRQoL improved significantly and the effects were maintained at follow-up after the treatment. Patients with refractory AP receive beneficial effects from EECP both in physical capacity and HRQoL. As other treatment options for this patient group are scarce, EECP should be offered to improve physical health and HRQoL in these patients.

    Full Text Available Growing evidence suggests that diet alteration affects sleep, but this has not yet been studied in adults with insomnia symptoms. We aimed to determine the effect of a six-month diet intervention on sleep among overweight and obese (Body mass index, BMI ≥ 25 kg/m2 men with chronic insomnia symptoms. Forty-nine men aged 30–65 years with chronic insomnia symptoms were randomized into diet (n = 28 or control (n = 21 groups. The diet group underwent a six-month individualized diet intervention with three face-to-face counseling sessions and online supervision 1–3 times per week; 300–500 kcal/day less energy intake and optimized nutrient composition were recommended. Controls were instructed to maintain their habitual lifestyle. Sleep parameters were determined by piezoelectric bed sensors, a sleep diary, and a Basic Nordic sleep questionnaire. Compared to the controls, the diet group had shorter objective sleep onset latency after intervention. Within the diet group, prolonged objective total sleep time, improved objective sleep efficiency, lower depression score, less subjective nocturnal awakenings, and nocturia were found after intervention. In conclusion, modest energy restriction and optimized nutrient composition shorten sleep onset latency in overweight and obese men with insomnia symptoms.

    Full Text Available Non-exclusive breast feeding in the early years of life is one of the most important factors in growth and development of infants. Therefore, exclusive breast feeding is recommended during the first six months of life. For determining the effective factors of non-exclusive breast feeding during the first six months of life, we used focus group discussion by participation of 60 mothers who had an infant under 6 months age and enjoyed non-exclusive breast feeding. Mothers divided into eight groups considering their occupation and number of child. All groups reported scanty of mother’s milk, mother’s occupation, mother’s illness, mother’s comfort, wrong beliefs, infant’s illness, doctors and health care providers recommendations, infant’s dependency to feeding bottle and pacifiers as the most frequent factors in using nonexclusive breast feeding. All mothers believed that health care centers, relatives and older members of family, books and pamphlets, mass media, physicians were their effective sources of awareness and promotion of exclusive breast feeding. Considering the presented ideas in all groups, it is realized that mothers during their pregnancy have sparse information about exclusive breast feeding and because of lack of enough essential training, some socio – cultural beliefs affects non-exclusive breast feeding. Mass media and especial training programs should be implemented to promote exclusive breast feeding in Bushehr Port.

    Full Text Available Objective: Postnatal tissue accretion in preterm infants differs from those in utero, affecting body composition (BC and lifelong morbidity. Length normalized BC data allows infants with different body lengths to be compared and followed longitudinally. This study aims to analyze BC of preterm and term infants during the first six months of life. Methods: The BC data, measured using dual energy X-ray absorptiometry, of 389 preterm and 132 term infants from four longitudinal studies were combined. Fat-mass/length2 (FMI and fat-free mass/length2 (FFMI for postmenstrual age were calculated after reaching full enteral feeding, at term and two further time points up to six months corrected age. Results: Median FMI (preterm increased from 0.4 kg/m2 at 30 weeks to 2.5, 4.3, and 4.8 kg/m2 compared to 1.7, 4.7, and 6 kg/m2 in term infants at 40, 52, and 64 weeks, respectively. Median FFMI (preterm increased from 8.5 kg/m2 (30 weeks to 11.4 kg/m2 (45 weeks and remained constant thereafter, whereas term FFMI remained constant at 11 kg/m2 throughout the tested time points. Conclusion: The study provides a large dataset of length normalized BC indices. Followed longitudinally, term and preterm infants differ considerably during early infancy in the pattern of change in FMI and FFMI for age.

    Although previous studies have extensively documented the cross-sectional relationship between cognitive impairment and psychological distress, findings relating to their longitudinal associations remains mixed. The present study examines the longitudinal associations and mutual influence between cognitive functioning and psychological distress across six months among community-dwelling elderly in Hong Kong. A total of 162 older adults (40 males; M age  = 69.8 years, SD = 6.4) were administered objective and subjective measures of cognitive functioning, as well as self-reported ratings of distress, at two time points six months apart. Using structural equation modeling, we tested the cross-lagged relationships between cognitive functioning and distress. Our cross-lagged model indicated that cognitive functioning at baseline significantly predicted subsequent psychological distress. However, distress was not significantly associated with subsequent cognitive functioning. Additionally, the objective and subjective measures of cognitive functioning were not significantly correlated. These findings suggested that distress may occur as a consequence of poorer cognitive functioning in elderly, but not vice versa. The lack of correlation between objective and subjective cognitive measures suggested that the participants may not have adequate insight into their cognitive abilities. The implications of these findings are discussed. Copyright © 2018. Published by Elsevier B.V.

    Full Text Available Abstract Background Breastfeeding initiation rates in some developed countries are high (98 % in Sweden and 96 % in Australia whereas in others, they are not as favourable (46 % to 55 % in Ireland. Although the World Health Organization recommends exclusively breastfeeding for six months, 15 % of Australian women, 11 % of Swedish women and less than 7 % of Irish women achieve this goal. Awareness of what women in different countries perceive as essential breastfeeding support is a gap in our knowledge. Methods Our aim was to explore Australian, Irish and Swedish women’s perceptions of what assisted them to continue breastfeeding for six months. An exploratory design using critical incident techniques was used. Recruitment occurred through advertisements in local newspapers and on social networking platforms. Initial sampling was purposive, followed by snowball sampling. Telephone interviews were conducted with 64 Irish, 139 Swedish and 153 Australian women who responded to one question “what has assisted you to continue breastfeeding for at least six months?” Content analysis was conducted and common categories determined to allow comparison of frequencies and priority ranking. Results Categories reflected the individual mother, her inner social network, her outer social network (informal support either face to face or online, and societal support (health professionals, work environment and breastfeeding being regarded as the cultural norm. Categories ranked in the top five across the three countries were ‘informal face to face support’ and ‘maternal determination’. Swedish and Australian women ranked “health professional support” higher (first and third respectively than Irish women who ranked ‘informal online support’ as second compared to ninth and tenth for Swedish and Australian women. Conclusions The support required to assist breastfeeding women is complex and multi-faceted. Although common international

    Full Text Available Abstract Background In the year after birth one in six women has a depressive illness, 94% experience at least one major health problem (e.g. back pain, perineal pain, mastitis, urinary or faecal incontinence, 26% experience sexual problems and almost 20% have relationship problems with partners. Women with depression report less practical and emotional support from partners, less social support, more negative life events, and poorer physical health and see factors contributing to depression as lack of support, isolation, exhaustion and physical health problems. Fewer than one in three seek help in primary care despite frequent health care contacts. Methods Primary care and community-based strategies embedded in existing services were implemented in a cluster-randomised trial involving 16 rural and metropolitan communities, pair-matched, within the State of Victoria, Australia. Intervention areas were also provided with a community development officer for two years. The primary aim was to reduce the relative risk of depression by 20% in mothers six months after birth and to improve their physical health. Primary outcomes were obtained by postal questionnaires. The analysis was by intention-to-treat, unmatched, adjusting for the correlated nature of the data. Results 6,248 of 10,144 women (61.6% in the intervention arm and 5057/ 8,411 (60.1% in the comparison arm responded at six months, and there was no imbalance in major covariates between the two arms.

    Full Text Available Abstract Background Agricultural workers experience high rates of occupational injury. There is a lack of analytic studies which provide detailed occupational exposure information to inform intervention development. Methods A feasibility study simulating a six month prospective cohort study was designed and undertaken. The levels of farm and worker participation and retention were analysed to determine the feasibility of the methods for wider deployment. Results Recruitment levels were comparable with other studies, with 24% of farms and 36% of non-owner workers participating. Once recruited, retention was high at 85% and 86% respectively. Conclusions The main challenges identified were in the recruitment process. Once recruited, farms and workers tended to complete the study, indicating that prospective studies in this the agricultural workforce may be feasible. Issues encountered and potential solutions for future studies are discussed.

    The purpose of this study was to assess the value of intra-articular fluid injection under pressure, as a technique suggested for temporo-mandibular joint (TMJ) closed-lock treatment, and to determine if there is a persisting lock resolution in time. Twelve patients were studied at our centre, with a diagnosis of TMJ closed-lock, not amenable with conventional therapies. All patients underwent a MRI scan, confirming the presence of anteriorly displaced disk. This technique is based on intra-articular injection of anaesthetic (mepivacaine cloridrate) under pressure, using the so called pumping technique, that allows an inferior distraction of the condyle. The study has a six months follow-up. After closed-lock resolution all patients underwent physiotherapy with guided mouth opening, for one month. Mandibular function (maximal mouth opening) increased on average of 20.2 mm after treatment, and of 21.1 mm six months later (p=0.00000; with p<0.005). Pain decreased on average from VAS=6.75 to VAS=0.3 (p=0.00001; with p<0.005). The masticatory efficiency improved from VAS=5.25 to VAS=8.75 (p=0.002; p<0.005). Functional TMJ limitation level is significantly increased (p=0.002; p<0.005). Also, patient's efficacy judgement (mean value 3.58= good) and tolerability judgement (mean value 2.92=good) indicate that this therapy is well accepted. This technique is easy to perform, well tolerated and does not need specific instruments: it permits the resolution of TMJ closed-lock, decreases the pain and improves masticatory efficiency. All these effects persist in time. Subjects with recent closed-lock have an immediate and complete functional recovery while patients with chronic closed-lock do not.

    2007-12-01

    Full Text Available Abstract Background While fathers were neglected for a long time in research investigating families of pediatric patients, there are now a few studies available on fathers' posttraumatic stress symptoms (PTSS and posttraumatic stress disorder (PTSD. However, little is known about the course of PTSS and PTSD in fathers of pediatric patients. The present study aimed to compare the prevalence and course of PTSS and PTSD in fathers of children with different chronic and acute conditions and to identify factors that contribute to fathers' PTSS. Methods Sixty-nine fathers of children newly diagnosed with either cancer, type I diabetes mellitus, or epilepsy and 70 fathers of children suffering from an unintentional injury completed questionnaires at 4–6 weeks (Time 1 and six months (Time 2 after diagnosis or injury. Results Noticeable PTSD rates were found in fathers of children with a chronic disease (26% at Time 1 and 21% at Time 2, respectively. These rates were significantly higher than rates found in fathers of children with unintentional injuries (12% at Time 1 and 6% at Time 2, respectively. Within six months after the child's diagnosis or accident a decrease in severity of PTSS was observed in both groups. Significant predictors of PTSS at Time 2 were the father's initial level of PTSS, the child's medical condition (injuries vs. chronic diseases and functional status, the father's use of dysfunctional coping strategies, and father's level of neuroticism. Conclusion Our findings suggest that fathers with initially high PTSS levels are at greater risk to experience PTSS at follow-up, particularly fathers of children with a chronic disease. Sensitizing health care professionals to the identification of PTSS symptoms but also to indicators of neuroticism and the use of specific coping strategies early in the treatment course is essential for the planning and implementation of adequate intervention strategies.

    Full Text Available The optimal duration of preventive therapy for tuberculosis (TB among HIV-infected persons in TB-endemic countries is unknown.An open-label randomized clinical trial was performed and analyzed for equivalence. Seven hundred and twelve HIV-infected, ART-naïve patients without active TB were randomized to receive either ethambutol 800 mg and isoniazid 300 mg daily for six-months (6EH or isoniazid 300 mg daily for 36-months (36H. Drugs were dispensed fortnightly and adherence checked by home visits. Patients had chest radiograph, sputum smear and culture performed every six months, in addition to investigations if they developed symptoms. The primary endpoint was incident TB while secondary endpoints were all-cause mortality and adverse events. Survival analysis was performed on the modified intent to treat population (m-ITT and rates compared.Tuberculosis developed in 22 (6.4% of 344 subjects in the 6EH arm and 13 (3.8% of 339 subjects in the 36H arm with incidence rates of 2.4/100 py (95%CI- 1.4-3.5 and 1.6/100 py (95% CI-0.8-3.0 with an adjusted rate ratio (aIRR of 1.6 (0.8-3.2. Among TST-positive subjects, the aIRR of 6EH was 1.7 (0.6-4.3 compared to 36H, p = 0.8. All-cause mortality and toxicity were similar in the two arms. Among 15 patients with confirmed TB, 4 isolates were resistant to isoniazid and 2 were multidrug-resistant.Both regimens were similarly effective in preventing TB, when compared to historical incidence rates. However, there was a trend to lower TB incidence with 36H. There was no increase in isoniazid resistance compared to the expected rate in HIV-infected patients. The trial is registered at ClinicalTrials.gov, NCT00351702.

    The treatment of hyperthyroidism is aimed at improving health-related quality of life (HRQoL) and reducing morbidity and mortality. However, few studies have used validated questionnaires to assess HRQoL prospectively in such patients. The purpose of this study was to assess the impact of hyperthyroidism and its treatment on HRQoL using validated disease-specific and generic questionnaires. This prospective cohort study enrolled 88 patients with Graves' hyperthyroidism and 68 with toxic nodular goiter from endocrine outpatient clinics at two Danish university hospitals. The patients were treated with antithyroid drugs, radioactive iodine, or surgery. Disease-specific and generic HRQoL were assessed using the thyroid-related patient-reported outcome (ThyPRO) and the Medical Outcomes Study 36-item Short Form (SF-36), respectively, evaluated at baseline and six-month follow-up. The scores were compared with those from two general population samples who completed ThyPRO (n = 739) and SF-36 (n = 6638). Baseline scores for patients with Graves' hyperthyroidism and toxic nodular goiter were significantly worse than those for the general population scores on all comparable ThyPRO scales and all SF-36 scales and component summaries. ThyPRO scores improved significantly with treatment on all scales in Graves' hyperthyroidism and four scales in toxic nodular goiter, while SF-36 scores improved on five scales and both component summaries in Graves' hyperthyroidism and only one scale in toxic nodular goiter. In Graves' hyperthyroidism, large treatment effects were observed on three ThyPRO scales (Hyperthyroid Symptoms, Tiredness, Overall HRQoL) and moderate effects on three scales (Anxiety, Emotional Susceptibility, Impaired Daily Life), while moderate effects were seen in two ThyPRO scales in toxic nodular goiter (Anxiety, Overall HRQoL). However, significant disease-specific and generic HRQoL deficits persisted on multiple domains across both patient groups. Graves

    2010-04-01

    Full Text Available The effect of polycyclic aromatic hydrocarbons (PAHs on Galician sandy beach ecosystems, six months after the Prestige oil spill, was evaluated using the meiobenthos at a higher taxon level as an indicator. Meiobenthos community structure, environmental variables and sediment PAH content from six affected exposed beaches were studied and compared with three reference sites. They were also compared with data from polluted beaches obtained during the first days of the spill. Significant amounts of PAHs were found in affected beach sediments and both univariate and multivariate analyses showed differences between affected and reference beaches. Correlation analyses between PAH content and the meiobenthos community structure showed that 1,2-dimethylnaphthalene (C2-NAPH and 1-methylphenanthrene (C-PHEN affected both the community structure and the abundance of the main taxa. These two PAHs seem to be responsible for the low meiofauna density values, which suggests that there is a relationship between the oil spill and the differences between affected and reference localities.

Methods. 270 eligible women were randomized to either one of the three treatments: 40 g soy flour (whole soy group, 40 g low-fat milk powder + 63 mg daidzein (daidzein group, or 40 g low-fat milk powder (placebo group daily each for 6 months. Anthropometric indicators and body composition were measured before and after intervention. Results. 253 subjects completed the study with good compliance. Urinary isoflavones levels suggested good compliance of subjects with supplementation. Whole soy and purified daidzein had no significant effect on body weight, body mass index (BMI, waist and hip circumferences, waist to hip ratio (WHR, body fat percentage, fat mass, and free fat mass. Conclusion. Six-month consumption of whole soy and purified daidzein at provided dosage had no improvement on body weight and composition compared with isocaloric milk placebo among prehypertensive equol-producing postmenopausal women.

    The characterization of oligosaccharides in the feces of breast-fed babies is a valuable tool for monitoring the gastrointestinal fate of human milk oligosaccharides (HMOs). In the present study we monitored fecal oligosaccharide profiles together with the HMO-profiles of the respective breast milks up to six months postpartum, by means of capillary electrophoresis-laser induced fluorescence detection and mass spectrometry. Eleven mother/child pairs were included. Mother's secretor- and Lewis-type included all combinations [Le(a-b+), Le(a+b-), Le(a-b-)]. The fecal HMO-profiles in the first few months of life are either predominantly composed of neutral or acidic HMOs and are possibly effected by the HMO-fingerprint in the respective breast milk. Independent of the initial presence of acidic or neutral fecal HMOs, a gradual change to blood-group specific oligosaccharides was observed. Their presence pointed to a gastrointestinal degradation of the feeding-related HMOs, followed by conjugation with blood group specific antigenic determinants present in the gastrointestinal mucus layer. Eleven of these 'hybrid'-oligosaccharides were annotated in this study. When solid food was introduced, no HMOs and their degradation- and metabolization products were recovered in the fecal samples.

    The control of viral replication is essential in the highly active antiretroviral therapy (HAART), and adherence to therapy is instrumental for such control. Individual and external factors influence adhesion to the use of antiretroviral (ARV) drugs. This is a cross-sectional study to investigate factors associated with non-adherence to HAART in AIDS patients in Salvador, Bahia State, Brazil, with age ≥ 13 years and first prescription in 2009. Data was collected from patient charts and pharmacy records. From a total of 216 patients, 65.3% were males; mean age 37.8 ± 9.5 years; single, 67.9%; heterosexual, 64%; more than 8 years of school education, 65.3%; alcohol users, 61.5%; non-smokers, 75,1% or non-illicit drug users, 93.7%. A proportion of 94% started ARV therapy with TCD4+ drug reaction. The prevalence of non-adherence was 25%. The variables associated were: longer time between HIV infection and AIDS (aOR = 3.9), adverse drug reaction (aOR = 2.4), under 34 years of age (aOR = 2.2), less than 8 years of school education (aOR = 2.2) and illicit drugs use (aOR = 2.6). A high-non-adherence rate is an important problem within the first six months of HAART.

    The aim was to evaluate the clinical effect of a dentifrice containing 0.3% Magnolia extract on dental plaque and gingivitis. The trial was a 6-month double-blind, stratified, randomized and 2-armed parallel group study. Forty-six subjects in the test group brushed their teeth with a dentifrice containing 0.3% Magnolia extract and 48 subjects in the control group brushed with a placebo dentifrice. Plaque and gingivitis were assessed at baseline, 3 and 6 months. There was a significantly larger gingivitis reduction in the Magnolia group than in the control group (0.26 ± 0.11 versus 0.11 ± 0.12) (P gingival units Gingival Index (GI score 0) in the Magnolia group than in the control group (149% versus 31%) and a larger reduction in inflamed gingival units (GI score 2/3) (60% versus 30%). Furthermore, at sites with similar amounts of plaque, less clinical signs of gingival inflammation were observed in the Magnolia group than in the control group. Six months' unsupervised use of a dentifrice containing 0.3% Magnolia extract resulted in significantly greater gingivitis reduction than a corresponding control dentifrice. © 2013 John Wiley & Sons A/S.

    Nuclear medicine procedures have carried out in the Clinical Center of Montenegro - Podgorica since 2006 by the dual-headed SPECT and Digital gamma camera NUCLINE Spirit DH-V. In the first six months of the gamma camera use (from September 2006 to March 2007) examinations of skeleton, kidneys, thyroid and lung were performed. For diagnostic skeletal imaging (102 patients) the radiopharmaceutical 99m Tc-MDP is used, and administered activities were in the range from 555 to 740 MBq. For thyroid imaging (203 patients) 99m Tc-pertechnetate is used, and administered activities were in the range (37-111) MBq. Lung imaging is performed for 3 patients, using 99m Tc-MAA and administered activities in the range (111-185) MBq. Renal imaging is carried out for 72 patients: 42 dynamic studies of kidneys were performed with 99m Tc-DTPA and administered activities from 207 to 282 MBq, and 30 static kidneys scintigraphies were performed using the radiopharmaceutical 99m Tc-DMSA. 6 patients in the last mentioned group were children with year of birth between 2000 and 2006, and administered activities were from 16.6 to 55.5 MBq. In the same group, activities 28.5 MBq, 74.4 MBq and 120 MBq were administered to three patients with age between 6 and 18 years, and in the other cases, administered activities to the patients (adults) were in the range (59.2 to 196) MBq. The administered activities presented here are basis for further estimations of cumulated activity and absorbed dose to the various organs, which is useful for comparison of the average dose to patient organs in various nuclear medicine procedures and calculation of effective dose equivalent and total effective dose, significant for an estimation of potential risk due to the radioactivity administered to a patient during nuclear medicine procedures. It is very important for procedures optimization and improvement of the radiation protection. (author)

    The outbreak of the Ebola virus disease (EVD) in 2014 led to massive dropouts in HIV care in Guinea. Meanwhile, Médecins Sans Frontières (MSF) was implementing a six-monthly appointment spacing approach adapted locally as Rendez-vous de Six Mois (R6M) with an objective to improve retention in care. We sought to evaluate this innovative model of ART delivery in circumstances where access to healthcare is restricted. A retrospective cohort study in 2014 of the outcome of a group of stable patients (viral load ≤1000 copies/μl) enrolled voluntarily in R6M compared with a group of stable patients continuing standard one to three monthly visits in Conakry. Log-rank test and Cox proportional hazards model were used to compare rates of attrition (deaths and defaulters) from care between the two groups. A linear regression analysis was used to describe the trend or pattern in the number of clinical visits over time. Included were 1957 adults of 15 years old and above of whom 1166 (59.6%) were enrolled in the R6M group and 791 (40.4%) in the standard care group. The proportion remaining in care at 18 months and beyond was 90% in the R6M group; significantly higher than the 75% observed in the control group (p Conakry despite restricted access to healthcare caused by the devastating EVD on the health system in Guinea. R6M could be rolled out as the model of care for stable patients where and when feasible as a strategy likely to improve retention in HIV care.

    This collaboration, dubbed the MACHO Project (an acronym for MAssive Compact Halo Objects), has refurbished the 1.27-m, Great Melbourne Telescope at Mt. Stromlo and equipped it with a corrected {1°} FOV. The prime focus corrector yields a red and blue beam for simultaneous imaging in two passbands, 4500{ Angstroms}--6100{ Angstroms} and 6100{ Angstroms}--7900{ Angstroms}. Each beam is imaged by a 2x2 array of 2048x2048 pixel CCDs which are simultaneously read out from two amplifiers on each CCD. A 32 Megapixel dual-color image of 0.5 square degree is clocked directly into computer memory in less than 70 seconds. We are using this system to monitor more than 10(7) stars in the Magellanic Clouds for gravitational microlensing events and will soon monitor an additional 10(7) stars in the bulge of our galaxy. Image data goes directly into a reduction pipeline where photometry for stars in an image is determined and stored in a database. An early version of this pipeline has used a simple aperture photometry code and results from this will be presented. A more sophisticated PSF fitting photometry code is currently being installed in the pipeline and results should also be available at the meeting. The PSF fitting code has also been used to produce ~ 10(7) photometric measurements outside of the pipeline. This poster will present details of the instrumentation, data pipeline, observing conditions (weather and seeing), reductions and analyses for the first six months of dual-color observing. Eventually, we expect to be able to determine whether MACHOs are a significant component of the galactic halo in the mass range of \\(10^{-6} M_{\\sun} < M \\ {lower .5exhbox {\\: \\buildrel < \\over \\sim ;}} \\ 100 M_{\\sun}\\).

    Full Text Available The primary aim of this study was to assess knee range of motion (ROM as well as patients’ reported pain, stiffness and function up to six months after total knee arthroplasty (TKA. The secondary aim was to analyze the extent to which knee ROM correlates with patient-rated outcome. A prospective study included 60 patients with primary TKA for osteorthritis, admitted at Physical Medicine and Rehabilitation Clinic from April 2009 to October 2014. The patients were evaluated at 4 time points: at admission and at discharge, as well as at follow-up at 3 and at 6 months after surgery. The outcome parameters included: active knee ROM, as well as pain, stiffness and function according to self reported Western Ontario and McMaster Universities Osteoarthritis (WOMAC questionnaire. Statistically highly significant improvement in flexion and extension was observed from admission to all other assessment time points (p<0.001. Also, statistically significant improvement of all three WOMAC subscales (pain, stiffness and function was found between all assessments points (p<0.001. According to values of Spearman correlation coefficient, there was significant negative correlation of flexion with all WOMAC subscales at all assessment points, whereas correlation of extension with any assessed outcome parameter was without significance. It can be concluded that in TKA patients all outcome measures improved significantly from admission to 6 months follow-up. Knee flexion ROM negatively and moderately to strongly correlated with pain, stiffness and function, whereas correlation of extension with any assessed outcome measure was without significance.

    Full Text Available Background: Despite the large number of studies conducted on breastfeeding, no studies have yet examined the direct and indirect effects of socio-personal factors and mental health on breastfeeding. Aim: This study aimed to analyze of the effects of mental health and socio-personal factors on breastfeeding in infants aged less than six months. Method: This analytical cross-sectional study was conducted on 465 eligible mothers visiting general health centers in a northern city of Iran, in 2015. Data were collected using the researcher-made scale of socio-personal factors of breastfeeding, Spielberger’s State-Trait Anxiety Inventory, Beck’s Depression Inventory, Cohen’s Perceived Stress Scale, the Breastfeeding Difficulties Questionnaire, the Access to Healthcare Questionnaire, and the Poor Health Behaviors Questionnaire. Results: The path analysis of the mental health variables showed that breastfeeding problems are associated through a direct path with depression, through an indirect path with stress, and through both paths with anxiety; a positive correlation was thus observed between these variables and breastfeeding problems. Poor health behaviors also contributed to mothers’ breastfeeding problems through a direct path and indirectly by affecting their level of depression. Income had the highest positive effect (B=0.66, while the number of children had the highest negative effect (B=-3.16 on breastfeeding problems through a direct path. Poor health behaviors had the highest positive effect (B=0.75 and family support had the highest negative effect (B=-0.11 on breastfeeding. Implications for Practice: The early diagnosis of poor postpartum mental health in mothers can help reduce breastfeeding problems.

    Intracoronary β-irradiation after rotational atherectomy may be a reasonable approach to prevent recurrent in-stent restenosis (ISR). This study was done to evaluate the feasibility and efficacy of β-radiation therapy with a 188 Re-MAG3-filled balloon following rotational atherectomy for ISR. Fifty consecutive patients with diffuse ISR (length >10 mm) in native coronary arteries underwent rotational atherectomy and adjunctive balloon angioplasty followed by β-irradiation using 188 Re-MAG3-filled balloon catheter. The radiation doses was 15 Gy at 1.0 mm deep into vessel wall. Mean length of the lesion and irradiated segment was 25.6±12.7 mm and 37.6±11.2 mm, respectively. The radiation was delivered successfully to all patients, with a mean irradiation time of 20.1±61 7 sec. No adverse event including myocardial infarction, death, or stent thrombosis occurred during the follow-up period (mean 10.3±3.7 mon) and non-target vessel revascularization was needed in one patient. Six-month binary angiographic restenosis rate was 10.4% (2 focal ISR and 3 edge restenosis) and loss index was 0.17±0.31. Irradiation using 188 Re-MAG3-filled balloon following rotational atherectomy for patients with diffuse ISR may improve the clinical and angiographic outcomes. Further prospective randomized trials are warranted to evaluate the synergistic effect of debulking and irradiation in patients with diffuse ISR

    Full Text Available Abstract Background Studies have shown that sub-optimal breastfeeding is major contributor to infant and young child mortality in Ethiopia. To address this problem, infant and young child feeding guideline was developed in 2004 and interventions have been going on based on the guidelines. There is no study that assessed whether the infant and child feeding practices are according the guideline or not. This study was carried out to assess sub-optimal breastfeeding practices and associated factors among infants from birth to six months in rural communities of Jimma Arjo Woreda in the Southwest Ethiopia. Methods A cross-sectional study was carried out from December to January 2009. Quantitative data were collected from a sample of 382 respondents supplemented by qualitative data generated using in-depth interviews of 15 index mothers. Multivariable logistic regression model was used to identify predictors of timely initiation of breast feeding and non-exclusive breast feeding among mother-infant pairs. Results More than three fourth of mothers breastfeed their infants sub-optimally. Thirty-seven percent of mothers initiated breastfeeding later than one hour after delivery, which was significantly associated with not attending formal education (AOR = 1.05[95%CI: 1.03, 1.94] and painful breastfeeding experiences (AOR = 5.02[95%CI: 1.01, 10.08]. The majority (67.02% of mothers had no knowledge about exclusive breastfeeding. Non-exclusive breastfeeding was negatively associated with child’s age of 0-2 months (AOR: 0.27[95%CI: 0.16, 0.47 and 3-4 months (AOR = 0.43 [95%CI: 0.25, 0.73 and ownership of radio (AOR = 0.56[95%CI: 0.37, 0.88], but positively associated with the practice of discarding colostrums (AOR = 1.78[95%CI: 1.09, 4.94]. Conclusion The findings showed that the majority of mothers sub-optimally breastfeed their children in the study area. As most of the mothers do not have knowledge on the exclusive breast feeding.

    Evidence suggests that family meals influence food intakes and behaviours, which in turn impact children's eating habits, diets and health. Mealtimes therefore offer potential as settings for health promotion. Given diet, health behaviours and health are often socioeconomically patterned, it is important to consider whether family meals differ by socioeconomic position (SEP). The Family Meals with Young Kids study was an online survey completed by parents in 2014. Mealtime characteristics measured included; frequency of shared meals across the day, duration and location of mealtimes, parental modelling, and parental perceived importance of the evening meal. Maternal education was used to assess SEP. The aims of this study were to describe family meal characteristics among Australian families with children aged six months to six years and to describe the socioeconomic patterning of these. Participants (n = 992) were mostly mothers (97%) with a university degree (71%). The evening meal was the most frequently reported meal eaten together with the responding parent and child (77% ≥ five nights/week). Snacks were least commonly eaten together (39% ≥ five days/week). The frequency of having everyone present for the evening meal was inversely associated with SEP (OR 0.70, CI 0.54-0.92). Parent rated importance of family meals was generally high and positively associated with higher SEP (OR 1.32, CI 1.00-1.76). Most children consumed breakfast (73%), lunch (58%) and dinner (82%) sitting at a table or bench and this was positively associated with higher SEP for all meal types (OR 1.61-2.37, p meals was inversely associated with SEP (OR 0.63, CI 0.54-0.72). Less than half of children (36%) watched TV during meals more than once a day. Australian families engage in many healthy mealtime behaviours. Evidence that parents share meals with children and place high value on mealtimes with children provides important opportunities for promoting healthy behaviours

    Full Text Available In sub-Saharan Africa, early mortality is high following initiation of antiretroviral therapy (ART. We investigated 6-month outcomes and factors associated with mortality in HIV-infected adults being assessed for ART initiation and presenting with weight loss, chronic fever or diarrhea, and with negative TB sputum microscopy.A prospective cohort study was conducted in Malawi, investigating mortality in relation to ART uptake, microbiological findings and treatment of opportunistic infection (OIs, 6 months after meeting ART eligibility criteria.Of 469 consecutive adults eligible for ART, 74(16% died within 6 months of enrolment, at a median of 41 days (IQR 20-81. 370(79% started ART at a median time of 18 days (IQR 7-40 after enrolment. Six-month case-fatality rates were higher in patients with OIs; 25/121(21% in confirmed/clinical TB and 10/50(20% with blood stream infection (BSI compared to 41/308(13% in patients with no infection identified. Median TB treatment start was 27 days (IQR 17-65 after enrolment and mortality [8 deaths (44%] was significantly higher among 18 culture-positive patients with delayed TB diagnosis compared to patients diagnosed clinically and treated promptly with subsequent culture confirmation [6/34 (18%;p = 0.04]. Adjusted multivariable analysis, excluding deaths in the first 21 days, showed weight loss >10%, low CD4 count, severe anemia, laboratory-only TB diagnosis, and not initiating ART to be independently associated with increased risk of death.Mortality remains high among chronically ill patients eligible for ART. Prompt initiation of ART is vital: more than half of deaths were among patients who never started ART. Diagnostic and treatment delay for TB was strongly associated with risk of death. More than half of deaths occurred without identification of a specific infection. ART programmes need access to rapid point-of-care-diagnostic tools for OIs.

    PurposeThe aim of this study is twofold: to determine the complication rate in computed tomography (CT)-guided biopsies and drainages, and to evaluate the value of postinterventional CT control scans.MethodsRetrospective analysis of 1,067 CT-guided diagnostic biopsies (n = 476) and therapeutic drainages (n = 591) in thoracic (n = 37), abdominal (n = 866), and musculoskeletal (ms) (n = 164) locations. Severity of any complication was categorized as minor or major. To assess the need for postinterventional CT control scans, it was determined whether complications were detected clinically, on peri-procedural scans or on postinterventional scans only.ResultsThe complication rate was 2.5 % in all procedures (n = 27), 4.4 % in diagnostic punctures, and 1.0 % in drainages; 13.5 % in thoracic, 2.0 % in abdominal, and 3.0 % in musculoskeletal procedures. There was only 1 major complication (0.1 %). Pneumothorax (n = 14) was most frequent, followed by bleeding (n = 9), paresthesia (n = 2), material damage (n = 1), and bone fissure (n = 1). Postinterventional control acquisitions were performed in 65.7 % (701 of 1,067). Six complications were solely detectable in postinterventional control acquisitions (3 retroperitoneal bleeds, 3 pneumothoraces); all other complications were clinically detectable (n = 4) and/or visible in peri-interventional controls (n = 21).ConclusionComplications in CT-guided interventions are rare. Of these, thoracic interventions had the highest rate, while pneumothoraces and bleeding were most frequent. Most complications can be detected clinically or peri-interventionally. To reduce the radiation dose, postinterventional CT controls should not be performed routinely and should be restricted to complicated or retroperitoneal interventions only.

    Full Text Available Background: Smoking reduction remains a pivotal issue in public health policy, but quit rates obtained with traditional quit-smoking therapies remain disappointingly low. Tobacco Harm Reduction (THR, aiming at less harmful ways of consuming nicotine, may provide a more effective alternative. One promising candidate for THR are electronic cigarettes (e-cigs. The aim of this study was to investigate the efficacy of second-generation e-cigs both in terms of acute craving-reduction in the lab and in terms of smoking reduction and experienced benefits/complaints in an eight-month Randomized Controlled Trial (RCT. Design: RCT with three arms. Methods: Participants (N = 48 unwilling to quit smoking were randomized into two e-cig groups and one control group. During three lab sessions (over two months participants, who had been abstinent for four hours, vaped/smoked for five minutes, after which we monitored the effect on craving and withdrawal symptoms. eCO and saliva cotinine levels were also measured. In between lab sessions, participants in the e-cig groups could use e-cigs or smoke ad libitum, whereas the control group could only smoke. After the lab sessions, the control group also received an e-cig. The RCT included several questionnaires, which repeatedly monitored the effect of ad libitum e-cig use on the use of tobacco cigarettes and the experienced benefits/complaints up to six months after the last lab session. Results: From the first lab session on, e-cig use after four hours of abstinence resulted in a reduction in cigarette craving which was of the same magnitude as when a cigarette was smoked, while eCO was unaffected. After two months, we observed that 34% of the e-cig groups had stopped smoking tobacco cigarettes, versus 0% of the control group (difference p < 0.01. After five months, the e-cig groups demonstrated a total quit-rate of 37%, whereas the control group showed a quit rate of 38% three months after initiating e-cig use. At

    ´s weight and skin folds, as well as with the child´s own previous weight and size. This was also true for maternal consumption of animal foods and fruits during pregnancy. A negative correlation was observed with the consumption of corn tortillas and beans. The correlation of several tests applied to the child at six months was positive with its complementary consumption, total energy and several foods, specially egg, milk and fruit around three months of age. Conclusions. Small variations in nutrition of the mother-child pairs from the poor rural community studied had consequences on the psychomotor development of the infant. These findings point to the need for more applied nutrition programs.

    Disuse typically uncouples bone formation from resorption, leading to bone loss which compromises bone mechanical properties and increases the risk of bone fracture. Previous studies suggest that bears can prevent bone loss during long periods of disuse (hibernation), but small sample sizes have limited the conclusions that can be drawn regarding the effects of hibernation on bone structure and strength in bears. Here we quantified the effects of hibernation on structural, mineral, and mechan...

    A randomized clinical trial was undertaken to investigate the relative efficacy of rational-emotive behavior therapy (REBT), cognitive therapy (CT), and pharmacotherapy in the treatment of 170 outpatients with nonpsychotic major depressive disorder. The patients were randomly assigned to one of the following: 14 weeks of REBT, 14 weeks of CT, or 14 weeks of pharmacotherapy (fluoxetine). The outcome measures used were the Hamilton Rating Scale for Depression and the Beck Depression Inventory. No differences among treatment conditions at posttest were observed. A larger effect of REBT (significant) and CT (nonsignificant) over pharmacotherapy at 6 months follow-up was noted on the Hamilton Rating Scale for Depression only. (c) 2008 Wiley Periodicals, Inc.

    Disuse typically uncouples bone formation from resorption, leading to bone loss which compromises bone mechanical properties and increases the risk of bone fracture. Previous studies suggest that bears can prevent bone loss during long periods of disuse (hibernation), but small sample sizes have limited the conclusions that can be drawn regarding the effects of hibernation on bone structure and strength in bears. Here we quantified the effects of hibernation on structural, mineral, and mechanical properties of black bear (Ursus americanus) cortical bone by studying femurs from large groups of male and female bears (with wide age ranges) killed during pre-hibernation (fall) and post-hibernation (spring) periods. Bone properties that are affected by body mass (e.g. bone geometrical properties) tended to be larger in male compared to female bears. There were no differences (p>0.226) in bone structure, mineral content, or mechanical properties between fall and spring bears. Bone geometrical properties differed by less than 5% and bone mechanical properties differed by less than 10% between fall and spring bears. Porosity (fall: 5.5+/-2.2%; spring: 4.8+/-1.6%) and ash fraction (fall: 0.694+/-0.011; spring: 0.696+/-0.010) also showed no change (p>0.304) between seasons. Statistical power was high (>72%) for these analyses. Furthermore, bone geometrical properties and ash fraction (a measure of mineral content) increased with age and porosity decreased with age. These results support the idea that bears possess a biological mechanism to prevent disuse and age-related osteoporoses.

    Full Text Available A considerable amount of research suggests that breakfast omission and the frequent use of caffeinated energy drinks may be associated with undesirable effects, and particularly so in children and adolescents. The current paper presents cross-sectional and longitudinal data from the Cornish Academies Project to investigate the effects of consuming energy drinks and missing breakfast on stress, anxiety, and depression in a cohort of secondary school children from the South West of England. Questionnaires were administered at two time-points (spaced six months apart to collect information relating to diet and lifestyle over the previous six months, demographic and school data were acquired through the School Information Management System, and single-item measures of stress, anxiety, and depression were administered at the second time-point only. Associations between breakfast and energy drink consumption and stress, anxiety, and depression were investigated, and a multivariate approach was taken so that additional variance from diet, demography, and lifestyle could be controlled for statistically. Cross-sectional analyses showed that breakfast omission was consistently associated with negative outcomes, and that this was largely observed for both those who frequently consumed energy drinks and those who did not. However, cross-lag analyses showed that neither breakfast omission or energy drink consumption, alone or in combination, was predictive of stress, anxiety, or depression at six-month follow-up. This suggests that associations between breakfast and mental health may be bi-directional rather than breakfast being the causal factor.

  7. Six Month In Situ High-Resolution Carbonate Chemistry and Temperature Study on a Coral Reef Flat Reveals Asynchronous pH and Temperature Anomalies.

    Full Text Available Understanding the temporal dynamics of present thermal and pH exposure on coral reefs is crucial for elucidating reef response to future global change. Diel ranges in temperature and carbonate chemistry parameters coupled with seasonal changes in the mean conditions define periods during the year when a reef habitat is exposed to anomalous thermal and/or pH exposure. Anomalous conditions are defined as values that exceed an empirically estimated threshold for each variable. We present a 200-day time series from June through December 2010 of carbonate chemistry and environmental parameters measured on the Heron Island reef flat. These data reveal that aragonite saturation state, pH, and pCO2 were primarily modulated by biologically-driven changes in dissolved organic carbon (DIC and total alkalinity (TA, rather than salinity and temperature. The largest diel temperature ranges occurred in austral spring, in October (1.5 - 6.6°C and lowest diel ranges (0.9 - 3.2°C were observed in July, at the peak of winter. We observed large diel total pH variability, with a maximum range of 7.7 - 8.5 total pH units, with minimum diel average pH values occurring during spring and maximum during fall. As with many other reefs, the nighttime pH minima on the reef flat were far lower than pH values predicted for the open ocean by 2100. DIC and TA both increased from June (end of Fall to December (end of Spring. Using this high-resolution dataset, we developed exposure metrics of pH and temperature individually for intensity, duration, and severity of low pH and high temperature events, as well as a combined metric. Periods of anomalous temperature and pH exposure were asynchronous on the Heron Island reef flat, which underlines the importance of understanding the dynamics of co-occurrence of multiple stressors on coastal ecosystems.

    To determine the association of changes on nailfold capillaroscopy with clinical findings and genotype in children with juvenile dermatomyositis (DM), in order to identify potential differences in disease course over 36 months. At diagnosis of juvenile DM in 61 children prior to the initiation of treatment, tumor necrosis factor alpha (TNFalpha) -308 allele and DQA1*0501 status was determined, juvenile DM Disease Activity Scores (DAS) were obtained, and nailfold capillaroscopy was performed. The disease course was monitored for 36 months. Variations within and between patients were assessed by regression analysis. At diagnosis, shorter duration of untreated disease (P = 0.05) and a lower juvenile DM skin DAS (P = 0.035) were associated with a unicyclic disease course. Over 36 months, end-row loop (ERL) regeneration was associated with lower skin DAS (P nailfold capillaroscopy changes. The correlation of nailfold capillaroscopy results with cutaneous but not with musculoskeletal signs of juvenile DM over a 36-month period suggests that the cutaneous and muscle vasculopathies have different pathophysiologic mechanisms. These findings indicate that efforts to identify the optimal treatment of cutaneous features in juvenile DM require greater attention.

    This study aimed to determine whether or not the improvement of glycaemic control with 6-month exenatide therapy in type 2 diabetic patients with secondary failure to combined oral therapy is related to amelioration of β-cell function and/or insulin sensitivity and their combined product. Thirty-three patients with type 2 diabetes were investigated. Their β-cell function and insulin sensitivity were measured using Homoeostasis Model Assessment [HOMA-B, HOMA-S and HOMA hyperbolic product (BxS)]. Additional endpoints included changes in weight, HbA(1c) and plasma adiponectin, as well as baseline clinical and biological characteristics, as potential predictors of HbA(1c) response. After 6 months, unadjusted HOMA-B increased from 33 ± 24% to 43 ± 23% (P=0.0210), whereas there was no significant change in HOMA-S (from 58 ± 35% to 61 ± 40%). The hyperbolic product increased by a relative 70% (from 15 ± 7% to 22 ± 15%; P=0.0055). Body mass index decreased from 32.2 ± 5.1 kg/m(2) to 31.0 ± 4.8 kg/m(2) (PHOMA-B and hyperbolic product over a 6-month treatment period with no overall change in insulin sensitivity, despite weight loss. Thus, improved β-cell function rather than increased insulin sensitivity accounts for the bulk of HbA(1c) reduction following 6 months of exenatide treatment. Copyright © 2010 Elsevier Masson SAS.

    To inform the design of a pivotal randomized controlled trial of prophylactic intra-aortic balloon counterpulsation (IABC) in patients undergoing coronary artery bypass graft (CABG) at high risk of postoperative low cardiac output syndrome (LCOS). Inception cohort study. A total of 13 established cardiac centers in Australia, Canada, New Zealand, and the United Kingdom. Adult patients were eligible for inclusion if they were listed for CABG surgery and had 2 or more LCOS risk factors (low ejection fraction, severe left main coronary artery disease, redo sternotomy, unstable angina). Outcomes of interest were a composite outcome of in-hospital mortality, postoperative acute myocardial infarction (AMI), acute kidney injury (AKI), or stroke as well as 6-month vital status and quality of life using the EuroQol 5-dimensional questionnaire (EQ5D). The study included 136 participants over a 29-month period. Overall, in-hospital and 6-month mortality occurred in 7 (5%) and 11 (8%) participants, respectively. The composite outcome occurred in 60 (44%). The mean increase in EQ5D summary index at 6 months was 0.10 (standard deviation 0.24, p = 0.01). Perioperative AMI, AKI, or stroke significantly decreased the odds of a clinically meaningful improvement in quality of life (odds ratio 0.32; 95% confidence interval 0.13-0.79; p = 0.014). Preoperative IABC was used in 39 participants and did not predict postoperative outcomes. The study identified a group of patients at risk of LCOS in whom CABG surgery was associated with a substantial burden of perioperative morbidity. Preoperative IABC use was variable, supporting the need for further research. Copyright © 2018 Elsevier Ltd. All rights reserved.

    Two passive methods in the assessment of intradomiciliary infestation by Rhodnius ecuadoriensis were tested: (i) the Gomes Nu ez sensor box (GN), (ii) sheets of white typing paper and (iii) one active timed manual method. The study was carried out in the Alto Chicama River Valley, Province of Gran Chim , Department of La Libertad. The study design consisted of an initial searching of triatomines inside of the domestic environment by the manual capture active procedure (man/hour) covering all the studied houses. Then, matched pairs of GN boxes and paper sheets were simultaneously installed in the bedrooms of 207 households distributed in 19 localities. A comparative prospective trial of these passive detection devices were monitored at 2, 4 and, finally 6 months follow-up. Parasitological Trypanosoma rangeli and/or T. cruzi infections were investigated in two houses with high level of infestation by R. ecuadoriensis. 16.9% of the 207 households investigated by an initial active manual method were infested with R. ecuadoriensis. The proportion of infested houses fluctuated from 6.2 to 55.5% amongst the 19 localities investigated. T. rangeli natural infection was detected in R. ecuadoriensis specimens collected in two households. Parasite rates in the bugs ranged from 16.6 to 21.7% respectively. The most striking fact was an average rate of salivary gland infection ranging from 7.4 to 8.3%. At the end of the sixth month period, a cumulative incidence of 31.4% of positive GN boxes against 15.9% for paper sheets was recorded. All three methods combined detected domestic infestation in 129 (62.3%) of the 207 houses studied in the 19 localities. The range of houses infested varies from 6.7% to 92.9%. In areas with low bug density infestation rates, the methodology experienced in our studies, seems to be the best choice for investigations on domestic R. ecuadoriensis populations.

    Few exercise trials in cancer patients have reported longer-term follow-up. Here, we report a 6-month follow-up of exercise behavior and patient-rated outcomes from an exercise trial in breast cancer patients. Breast cancer patients initiating adjuvant chemotherapy (n = 242) were randomly assigned to usual care (n = 82), resistance exercise training (RET; n = 82), or aerobic exercise training (AET; n = 78) for the duration of their chemotherapy. At 6-month follow-up, participants were mailed a questionnaire that assessed quality of life, self-esteem, fatigue, anxiety, depression, and exercise behavior. Two hundred one (83.1%) participants provided 6-month follow-up data. Adjusted linear mixed-model analyses showed that, at 6-month follow-up, the RET group reported higher self-esteem [adjusted mean difference, 1.6; 95% confidence interval (95% CI), 0.1-3.2; P = 0.032] and the AET group reported lower anxiety (adjusted mean difference, -4.7; 95% CI, -0.0 to -9.3; P = 0.049) compared with the usual care group. Moreover, compared with participants reporting no regular exercise during the follow-up period, those reporting regular aerobic and resistance exercise also reported better patient-rated outcomes, including quality of life (adjusted mean difference, 9.5; 95% CI, 1.2-17.8; P = 0.025). Improvements in self-esteem observed with RET during breast cancer chemotherapy were maintained at 6-month follow-up whereas reductions in anxiety not observed with AET during breast cancer chemotherapy emerged at 6-month follow-up. Moreover, adopting a combined aerobic and resistance exercise program after breast cancer chemotherapy was associated with further improvements in patient-rated outcomes. Exercise training during breast cancer chemotherapy may result in some longer-term and late effects for selected patient-rated outcomes.

    Suicide risk evaluation is one of the most challenging assessments of patients with major depressive disorder (MDD). Initial risk evaluation might be insufficient in predicting emergence of suicidal ideation during the maintenance period. We aimed to elucidate factors associated with emergence or persistence of suicidal ideation 6 months after initiation of outpatient treatment in patients with MDD. A total of 300 participants with MDD defined by DSM-IV-TR criteria underwent face-to-face interview at baseline and follow-up phone interview at 6 months later. Severity of depression, suicidal ideation, and anxiety were evaluated. Among participants who did not report any suicidal idea at baseline, 10.9% reported suicidal ideation during the 6-month phone interview, while 28.4% of participants who reported suicidal ideation at baseline reported suicidal ideation during the phone interview. No significant difference in remission rate of depression was observed between the groups, but subjects without suicidal ideation at baseline had a higher rate of symptom improvement at the 6-month phone interview. After controlling for age, sex, baseline severity of suicide risk and depression and lifetime history of suicide attempts, emergence of suicidal ideation was significantly associated with anxiety level at baseline (t=2.127, p=0.039) and severity of depression symptoms at 6 month (t=-3.028, p=0.004); persistence of suicidal ideation was associated with severity of depression symptoms at 6 month (t=-4.962, psuicide risk of patients with MDD.

    To evaluate the efficacy of simplified dehydration protocols, in the absence of tubular occlusion, on bond strength and interfacial nanoleakage of a hydrophobic experimental adhesive blend to acid-etched, ethanol-dehydrated dentine immediately and after 6 months. Molars were randomly assigned to 6 treatment groups (n=5). Under pulpal pressure simulation, dentine crowns were acid-etched with 35% H(3)PO(4) and rinsed with water. Adper Scotchbond Multi-Purpose was used for the control group. The remaining groups had their dentine surface dehydrated with ethanol solutions: group 1=50%, 70%, 80%, 95% and 3x100%, 30s for each application; group 2 the same ethanol sequence with 15s for each solution; groups 3, 4 and 5 used 100% ethanol only, applied in seven, three or one 30s step, respectively. After dehydration, a primer (50% BisGMA+TEGDMA, 50% ethanol) was used, followed by the neat comonomer adhesive application. Resin composite build-ups were then prepared using an incremental technique. Specimens were stored for 24h, sectioned into beams and stressed to failure after 24h or after 6 months of artificial ageing. Interfacial silver leakage evaluation was performed for both storage periods (n=5 per subgroup). Group 1 showed higher bond strengths at 24h or after 6 months of ageing (45.6+/-5.9(a)/43.1+/-3.2(a)MPa) and lower silver impregnation. Bond strength results were statistically similar to control group (41.2+/-3.3(ab)/38.3+/-4.0(ab)MPa), group 2 (40.0+/-3.1(ab)/38.6+/-3.2(ab)MPa), and group 3 at 24h (35.5+/-4.3(ab)MPa). Groups 4 (34.6+/-5.7(bc)/25.9+/-4.1(c)MPa) and 5 (24.7+/-4.9(c)/18.2+/-4.2(c)MPa) resulted in lower bond strengths, extensive interfacial nanoleakage and more prominent reductions (up to 25%) in bond strengths after 6 months of ageing. Simplified dehydration protocols using one or three 100% ethanol applications should be avoided for the ethanol-wet bonding technique in the absence of tubular occlusion, as they showed decreased bond strength, more

    The present project investigated whether cardiac magnetic resonance (CMR) of aortic arch anomalies can be performed successfully in infants <6 months of age without the use of cardiac anesthesia or deep sedation. We performed a retrospective review of infants ≤6 months old from 2005 to 2009 who underwent either CMR or computed tomography angiography to investigate aortic arch abnormalities. The CMR procedure used a "feed and swaddle" protocol without deep sedation or cardiac anesthesia. Of the 52 infants referred for CMR, 24 underwent the feed and swaddle protocol (aged 2.6 ± 1.4 months). One patient awoke during the study, and examination of the remaining 23 yielded a definitive diagnosis (success rate 96%). The scanning time was 6.2 ± 3.1 minutes, with the large airways evaluation accounting for 1/2 the time. Single-shot axial steady-state free precession, in which the definitive diagnosis was made, accounted for 0.59 ± 0.3 minutes. Fifteen infants were diagnosed with a vascular ring. Of the 8 infants who underwent surgery, the diagnostic accuracy was 100%. During the same period, 19 patients, who had undergone computed tomography angiography (aged 1.67 ± 1.20 months), were referred for aortic arch evaluation. Of these 19 patients, 6 (32%) underwent sedation or anesthesia. The imaging time was 0.08 ± 0.06 minutes, significantly different from the CMR times (p <0.01). However, the overall room times (31.3 ± 22.3 and 35.8 ± 3.86 minutes, respectively) were not different between the CMR and angiographic groups. The radiation dose was 1.41 ± 1.03 mSv. In conclusion, CMR evaluation of aortic arch anomalies in children <6 months old can be successfully completed quickly using a feed and swaddle approach with high diagnostic accuracy. This protocol avoids the risks of sedation, as well as the radiation associated with computed tomography angiography. Copyright © 2011 Elsevier Inc. All rights reserved.

    The preschool years offer an opportunity to interrupt the trajectory toward obesity in black children. The Hip-Hop to Health Jr. Obesity Prevention Effectiveness Trial was a group-randomized controlled trial assessing the feasibility and effectiveness of a teacher-delivered weight control intervention for black preschool children. The 618 participating children were enrolled in 18 schools administered by the Chicago Public Schools. Children enrolled in the 9 schools randomized to the intervention group received a 14-week weight control intervention delivered by their classroom teachers. Children in the 9 control schools received a general health intervention. Height and weight, physical activity, screen time, and diet data were collected at baseline and post-intervention. At post-intervention, children in the intervention schools engaged in more moderate-to vigorous physical activity than children in the control schools (difference between adjusted group means=7.46 min/day, p=.02). Also, children in the intervention group had less total screen time (−27.8 min/day, p=.05). There were no significant differences in BMI, BMI Z score, or dietary intake. It is feasible to adapt an obesity prevention program to be taught by classroom teachers. The intervention showed positive influences on physical activity and screen time, but not diet. Measuring diet and physical activity in preschool children remains a challenge, and interventions delivered by classroom teachers require both intensive initial training and ongoing individualized supervision.

    Given the increasing focus on early mortality and readmission rates among patients with acute coronary syndrome (ACS), this study was designed to evaluate the accuracy of the GRACE risk score for identifying patients at high risk of 30-day post-discharge mortality and cardiovascular readmission. This was a retrospective study carried out in a single center with 4229 ACS patients discharged between 2004 and 2010. The study endpoint was the combination of 30-day post-discharge mortality and readmission due to reinfarction, heart failure or stroke. One hundred and fourteen patients had 30-day events: 0.7% mortality, 1% reinfarction, 1.3% heart failure, and 0.2% stroke. After multivariate analysis, the six-month GRACE risk score was associated with an increased risk of 30-day events (HR 1.03, 95% CI 1.02-1.04; p<0.001), demonstrating good discrimination (C-statistic: 0.79 ± 0.02) and optimal fit (Hosmer-Lemeshow p=0.83). The sensitivity and specificity were adequate (78.1% and 63.3%, respectively), and negative predictive value was excellent (99.1%). In separate analyses for each event of interest (all-cause mortality, reinfarction, heart failure and stroke), assessment of the six-month GRACE risk score also demonstrated good discrimination and fit, as well as adequate predictive values. The six-month GRACE risk score is a useful tool to predict 30-day post-discharge death and early cardiovascular readmission. Clinicians may find it simple to use with the online and mobile app score calculator and applicable to clinical daily practice. Copyright © 2014 Sociedade Portuguesa de Cardiologia.

    Full Text Available Abstract Objectives We investigated whether an intervention mainly consisting of a signed agreement between patient and physician on the objectives to be reached, improves reaching these secondary prevention objectives in modifiable cardiovascular risk factors six-months after discharge following an acute coronary syndrome. Background There is room to improve mid-term adherence to clinical guidelines' recommendations in coronary heart disease secondary prevention, specially non-pharmacological ones, often neglected. Methods In CAM-2, patients discharged after an acute coronary syndrome were randomly assigned to the intervention or the usual care group. The primary outcome was reaching therapeutic objectives in various secondary prevention variables: smoking, obesity, blood lipids, blood pressure control, exercise and taking of medication. Results 1757 patients were recruited in 64 hospitals and 1510 (762 in the intervention and 748 in the control group attended the six-months follow-up visit. After adjustment for potentially important variables, there were, between the intervention and control group, differences in the mean reduction of body mass index (0.5 vs. 0.2; p Conclusions At least in the short term, lifestyle changes among coronary heart disease patients are achievable by intensifying the responsibility of the patient himself by means of a simple and feasible intervention.

    To present a conceptual and measurement strategy that allows to objectively, sensitively evaluate intervention progress based on data of participants' perceptions of presenting problems. We used as an example an organization development intervention at a United States Veterans Affairs medical center. Within a year, the intervention addressed the hospital's initially serious problems and multiple stakeholders (employees, management, union representatives) reported satisfaction with progress made. Traditional quantitative outcome measures, however, failed to capture the strong positive impact consistently reported by several types of stakeholders in qualitative interviews. To address the paradox, full interview data describing the medical center pre- and post- intervention were examined applying a validated theoretical framework from another discipline: Psychotherapy research. The Assimilation model is a clinical-developmental theory that describes empirically grounded change levels in problematic experiences, e.g., problems reported by participants. The model, measure Assimilation of Problematic Experiences Scale (APES), and rating procedure have been previously applied across various populations and problem types, mainly in clinical but also in non-clinical settings. We applied the APES to the transcribed qualitative data of intervention participants' interviews, using the method closely replicating prior assimilation research (the process whereby trained clinicians familiar with the Assimilation model work with full, transcribed interview data to assign the APES ratings). The APES ratings summarized levels of progress which was defined as participants' assimilation level of problematic experiences, and compared from pre- to post-intervention. The results were consistent with participants' own reported perceptions of the intervention impact. Increase in APES levels from pre- to post-intervention suggested improvement, missed in the previous quantitative measures

    In accordance with Knowles's theory, self-directed learning (SDL) may be improved with tutorial strategies focused on guided reflection and critical analysis of the learning process. No evidence on effects on SDL abilities of different tutorial strategies offered to nursing students during the 1st clinical experience is available. To evaluate the effect of different tutorial strategies offered to nursing students on their SDL abilities. A pre-post intervention non-equivalent control group design was adopted in 2013. For the treatment group, structured and intensive tutorial interventions including different strategies such as briefing, debriefing, peer support, Socratic questioning, performed by university tutors were offered during the 1st clinical experience; for the control group, unstructured and non-intensive tutorial strategies were instead offered. Two Bachelor of Nursing Degree. Students awaiting their clinical experience (n=238) were the target sample. Those students who have completed the pre- and the post-intervention evaluation (201; 84.4%) were included in the analysis. SDL abilities were measured with the SRSSDL_ITA (Self Rating Scale of Self Directed Learning-Italian Version). A multiple linear regression analysis was developed to explore the predictive effect of individual, contextual and intervention variables. Three main factors explained the 36.8% of the adjusted variance in SDL scores have emerged: a) having received a lower clinical nurse-to-student supervision (B 9.086, β 2.874), b) having received higher level and structured tutorial intervention by university tutors (B 8.011, β 2.741), and c) having reported higher SDL scores at the baseline (B .550, β .556). A lower clinical nurse-to-student ratio (1:4), accompanied by unstructured and non-intensive tutorial intervention adopted by university tutors, seemed to be equivalent to an intensive clinical supervision (1:1) accompanied by higher level and structured tutorial strategies activated

    Tuberculosis (TB) patients who quit smoking have much better disease outcomes than those who continue to smoke. Behavioural support combined with pharmacotherapy is the most effective strategy in helping people to quit, in general populations. However, there is no evidence for the effectiveness of this strategy in TB patients who smoke. We will assess the safety, effectiveness and cost-effectiveness of cytisine - a low-cost plant-derived nicotine substitute - for smoking cessation in TB patients compared with placebo, over and above brief behavioural support. Two-arm, parallel, double-blind, placebo-controlled, multi-centre (30 sites in Bangladesh and Pakistan), individually randomised trial. TB treatment centres integrated into public health care systems in Bangladesh and Pakistan. Newly diagnosed (in the last four weeks) adult pulmonary TB patients who are daily smokers (with or without dual smokeless tobacco use) and are interested in quitting (n= 2,388). The primary outcome measure is biochemically verified continuous abstinence from smoking at six months post-randomization, assessed using Russell Standard criteria. The secondary outcome measures include continuous abstinence at 12 months, lapses and relapses; clinical TB outcomes; nicotine dependency and withdrawal; and adverse events. This is the first smoking cessation trial of cytisine in low- and middle-income countries evaluating both cessation and tuberculosis (TB) outcomes. If found effective, cytisine could become the most affordable cessation intervention to help TB patients who smoke. This article is protected by copyright. All rights reserved.

    The primary objective of this study was to evaluate the safety and the effect of D-tagatose on the glycemic control of subjects with type 2 diabetes as determined by HbA 1c levels at the end of 6 months of therapy using the subject's own baseline HbA 1c level as a comparator. The determination of the minimal dose required to cause a statistically significant reduction in HbA 1c was of particular interest. Eight weeks after screening, the qualifying subjects were randomized to receive one of three doses of D-tagatose: 2.5 g TID, 5.0 g TID or 7.5 g TID. Blood levels of HbA 1c , fasting blood glucose concentrations, plasma lipids, changes in body weight, changes in body mass index, and change in insulin levels were checked at each study visit and at the end of the study. Treatment success, as measured by the reduction of HbA 1c , was greatest for the 7.5 g D-tagatose dose group, although the difference between the treatments was not statistically significant. For fasting glucose, only the 7.5 g dosage group exhibited reductions from baseline at the 3- and 6-month time points. Mean body weights reduced in a dose-response fashion, with the 5.0 g and the 7.5 g D-tagatose doses providing the greatest reductions. D-tagatose at dosages of 2.5 g, 5.0 g, and 7.5 g TID for six months were well tolerated by this subject population. D-tagatose at 5.0 g TID was the minimal dose required to reduce HbA 1c . D-tagatose at 7.5 g TID provided the greatest effect in most measured efficacy parameters.

    Terminally ill cancer patients do not engage in end-of-life (EOL) care discussions or do so only when death is imminent, despite guidelines for EOL care discussions early in their disease trajectory. Most studies on patient-reported EOL care discussions are cross sectional without exploring the evolution of EOL care discussions as death approaches. Cross-sectional studies cannot determine the direction of association between EOL care discussions and patients' prognostic awareness, psychological well-being, and quality of life (QOL). We examined the evolution and associations of accurate prognostic awareness, functional dependence, physical and psychological symptom distress, and QOL with patient-physician EOL care discussions among 256 terminally ill cancer patients in their last six months by hierarchical generalized linear modeling with logistic regression and by arranging time-varying modifiable variables and EOL care discussions in a distinct time sequence. The prevalence of physician-patient EOL care discussions increased as death approached (9.2%, 11.8%, and 18.3% for 91-180, 31-90, and 1-30 days before death, respectively) but only reached significance in the last month. Accurate prognostic awareness facilitated subsequent physician-patient EOL care discussions, whereas better patient-reported QOL and more anxiety symptoms hindered such discussions. The likelihood of EOL care discussions was not associated with levels of physical symptom distress, functional dependence, or depressive symptoms. Physician-patient EOL care discussions for terminally ill Taiwanese cancer patients remain uncommon even when death approaches. Physicians should facilitate EOL care discussions by cultivating patients' accurate prognostic awareness early in their cancer trajectory when they are physically and psychologically competent, with better QOL, thus promoting informed and value-based EOL care decision making.

    The cases of childhood leukaemia found among children of the Sellafield workforce and those observed in the offspring of the Japanese bomb survivors are analysed using both exponential and linear forms of a relative risk model and employing dose estimates for the period 6 months pre-conception. The leukaemia relative risk coefficients for paternal (whole-body) exposure in this pre-conception period for children of Sellafield workers are found to be statistically incompatible with the (gonadal dose) coefficients applying to the offspring of the bomb survivors born in the period May 1946 to December 1946, i.e. born 9 to 16 months after the bombings. The incompatibility does not depend on whether the risks in the Japanese children are assumed to be a function simply of paternal gonadal dose or of combined paternal and maternal gonadal dose.

    Aims Due to the chronicity of cocaine dependence, practical and effective maintenance interventions are needed to sustain long-term abstinence. We sought to assess the effects of long-term employment-based reinforcement of cocaine abstinence after discontinuation of the intervention. Design Participants who initiated sustained opiate and cocaine abstinence during a 6-month abstinence reinforcement and training program worked as data entry operators and were randomly assigned to a group that could work independent of drug use (Control, n = 24), or an abstinence-contingent employment (n = 27) group that was required to provide cocaine- and opiate-negative urine samples to work and maintain maximum rate of pay. Setting A nonprofit data entry business. Participants Unemployed welfare recipients who persistently used cocaine while in methadone treatment. Measurements Urine samples and self-reports were collected every six months for 30 months. Findings During the employment year, abstinence-contingent employment participants provided significantly more cocaine-negative samples than controls (82.7% and 54.2%; P = .01, OR = 4.61). During the follow-up year, the groups had similar rates of cocaine-negative samples (44.2% and 50.0%; P = .93), and HIV-risk behaviors. Participants’ social, employment, economic, and legal conditions were similar in the two groups across all phases of the study. Conclusions Employment-based reinforcement effectively maintains long-term cocaine abstinence, but many patients relapse to use when the abstinence contingency is discontinued, even after a year of abstinence-contingent employment. Relapse could be prevented in many patients by leaving employment-based abstinence reinforcement in place indefinitely, which could be facilitated by integrating it into typical workplaces.

    Full Text Available Integrated community case management (iCCM involves delivery of simple medicines to children with pneumonia, diarrhea and/or malaria by community health workers (CHWs. Between 2010 and 2012, an iCCM intervention trial was implemented by Healthy Child Uganda. This study used qualitative tools to assess whether project stakeholders perceived that iCCM improved access to care for children under five years of age.The intervention involved training and equipping 196 CHWs in 98 study villages in one sub-county in Uganda in iCCM. During the eight-month intervention, CHWs assessed sick children, provided antimalarials (coartem for fever, antibiotics (amoxicillin for cough and fast breathing, oral rehydration salts/zinc for diarrhea, and referred very sick children to health facilities. In order to examine community perceptions and acceptability of iCCM, post-intervention focus groups and key respondent interviews involving caregivers, health workers, CHWs and local leaders were carried out by experienced facilitators using semi-structured interview guides. Data were analyzed using thematic analysis techniques.Respondents reported increased access to health care for children as a result of iCCM. Access was reportedly closer to home, available more hours in a day, and the availability of CHWs was perceived as more reliable. CHW care was reported to be trustworthy and caring. Families reported saving money especially due to reduced transportation costs, and less time away from home. Respondents also perceived better health outcomes. Linkages between health facilities and communities were reportedly improved by the iCCM intervention due to the presence of trained CHWs in the community.iCCM delivered by CHWs may improve access to health care and is acceptable to families. Policymakers should continue to seek opportunities to implement and support iCCM, particularly in remote communities where there are health worker shortages.

    Impairments in attention and memory are common sequelae following paediatric acquired brain injury (ABI). While it has been established that such impairments are long-term and, therefore, affect quality-of-life, there is a scarcity of evidence-based interventions to treat these difficulties. The current study aimed to pilot the efficacy of the Amsterdam Memory and Attention Training for Children (Amat-c: English version) using both neuropsychological and ecologically sensitive measures. It was expected that children with attention and memory difficulties post-ABI would show improved performance post-intervention on cognitive and ecological measures, with maintenance at 6 months post-intervention. Ten children with an ABI, between the ages of 8-13 years at the time of recruitment were identified through audits of presentations to a metropolitan paediatric hospital. Each child underwent screening, the 18 week intervention programme, pre-intervention, immediate and 6 month post-intervention assessments. Findings supported the hypothesis that children would show post-intervention (immediate and 6 month) improvement in areas of attention and memory, with generalization to everyday life. Preliminary results provide support for the efficacy of the Amat-c post-childhood ABI. A larger study is needed to confirm these findings, as a reduction in attention and memory difficulties will enhance everyday functioning.

    Integration of family planning counselling and method provision into safe abortion services is a key component of quality abortion care. Numerous barriers to post-abortion family planning (PAFP) uptake exist. This study aimed to evaluate the effect of a quality management intervention for providers on PAFP uptake. We conducted a pre- and post-intervention study between November 2015 and July 2016 in nine private clinics in Western Kenya. We collected baseline and post-intervention data using in-person interviews on the day of procedure, and follow-up telephone interviews to measure contraceptive uptake in the 2 weeks following abortion. We also conducted semi-structured interviews with providers. The intervention comprised a 1-day orientation, a counselling job-aide, and enhanced supervision visits. The primary outcome was the proportion of clients receiving any method of PAFP (excluding condoms) within 14 days of obtaining an abortion. Secondary outcomes were the proportion of clients receiving PAFP counselling, and the proportion of clients receiving long-acting reversible contraception (LARC) within 14 days of the service. We used chi-squared tests and multivariate logistic regression to determine whether there were significant differences between baseline and post-intervention, adjusting for potential confounding factors and clustering at the clinic level. Interviews were completed with 769 women, and 54% (414 women) completed a follow-up telephone interview. Reported quality of counselling and satisfaction with services increased between baseline and post-intervention. Same-day uptake of PAFP was higher at post-intervention compared to baseline (aOR 1.94, p quality of their services.

    Full Text Available For Donald Trump ‘America First’ means ‘America First.’ Canada and likeminded nations will have to get used to it. Canada will have to actively engage with Congress, the states and the private and public interests that drive the American agenda. We will also have to put more effort and contribute more to the rules-based order of which we have been a beneficiary. Traditional statecraft is based on predictability and stability, both hallmarks of U.S. post-war foreign policy practised by both Democrats and Republicans. Predictable, Mr. Trump is not. The deliberation and careful planning that characterized the Obama administration have been replaced by Mr. Trump’s reliance on gut and instinct. Such unpredictability will continue to create heartburn inside foreign chancelleries, whether friend or foe. Where once the USA was prepared to cover the spread on trade and security, under Donald Trump there will be more take than give. Now, Canada and the allies will have to make their own investments in hard power to preserve collective security. But less dependence and reliance on US leadership and more collective responsibility would be a good thing. Middle powers, like Canada, will have to step up their diplomacy, both collective and individual. Focusing on their own niche capacities they will have to shore up the space left by Trump Administration decisions on climate, migration and at the international institutions that sustain the rules-based order. Ironically, one effect of the Trump presidency may be to make the western alliance stronger.

    Depression and anxiety disorders in young people are a global health concern. Parents have an important role in reducing the risk of these disorders, but cost-effective, evidence-based interventions for parents that can be widely disseminated are lacking. This study aimed to examine the postintervention effects of the Partners in Parenting (PiP) program on parenting risk and protective factors for adolescent depression and anxiety, and on adolescent depression and anxiety symptoms. A two-arm randomized controlled trial was conducted with 359 parent-adolescent dyads, recruited primarily through schools across Australia. Parents and adolescents were assessed at baseline and 3 months later (postintervention). Parents in the intervention condition received PiP, a tailored Web-based parenting intervention designed following Persuasive Systems Design (PSD) principles to target parenting factors associated with adolescents' risk for depression and anxiety problems. PiP comprises a tailored feedback report highlighting each parent's strengths and areas for improvement, followed by a set of interactive modules (up to nine) that is specifically recommended for the parent based on individually identified areas for improvement. Parents in the active-control condition received a standardized package of five Web-based factsheets about adolescent development and well-being. Parents in both conditions received a 5-min weekly call to encourage progress through their allocated program to completion. Both programs were delivered weekly via the trial website. The primary outcome measure at postintervention was parent-reported changes in parenting risk and protective factors, which were measured using the Parenting to Reduce Adolescent Depression and Anxiety Scale (PRADAS). Secondary outcome measures were the adolescent-report PRADAS, the parent- and child-report Short Mood and Feelings Questionnaire (depressive symptoms), and parent- and child-report Spence Children's Anxiety Scale

    The purpose of this methodological study was to to provide insight into the under-addressed issue of the longitudinal predictive ability of mapping models. Post-intervention predicted and reported utilities were compared, and the effect of disease severity on the observed differences was examined. A cohort of 120 rheumatoid arthritis (RA) patients (60.0% female, mean age 59.0) embarking on therapy with biological agents completed the Modified Health Assessment Questionnaire (MHAQ) and the EQ-5D at baseline, and at 3, 6 and 12 months post-intervention. OLS regression produced a mapping equation to estimate post-intervention EQ-5D utilities from baseline MHAQ data. Predicted and reported utilities were compared with t test, and the prediction error was modeled, using fixed effects, in terms of covariates such as age, gender, time, disease duration, treatment, RF, DAS28 score, predicted and reported EQ-5D. The OLS model (RMSE = 0.207, R(2) = 45.2%) consistently underestimated future utilities, with a mean prediction error of 6.5%. Mean absolute differences between reported and predicted EQ-5D utilities at 3, 6 and 12 months exceeded the typically reported MID of the EQ-5D (0.03). According to the fixed-effects model, time, lower predicted EQ-5D and higher DAS28 scores had a significant impact on prediction errors, which appeared increasingly negative for lower reported EQ-5D scores, i.e., predicted utilities tended to be lower than reported ones in more severe health states. This study builds upon existing research having demonstrated the potential usefulness of mapping disease-specific instruments onto utility measures. The specific issue of longitudinal validity is addressed, as mapping models derived from baseline patients need to be validated on post-therapy samples. The underestimation of post-treatment utilities in the present study, at least in more severe patients, warrants further research before it is prudent to conduct cost-utility analyses in the context

  7. TLR accessory molecule RP105 (CD180 is involved in post-interventional vascular remodeling and soluble RP105 modulates neointima formation.

    Full Text Available BACKGROUND: RP105 (CD180 is TLR4 homologue lacking the intracellular TLR4 signaling domain and acts a TLR accessory molecule and physiological inhibitor of TLR4-signaling. The role of RP105 in vascular remodeling, in particular post-interventional remodeling is unknown. METHODS AND RESULTS: TLR4 and RP105 are expressed on vascular smooth muscle cells (VSMC as well as in the media of murine femoral artery segments as detected by qPCR and immunohistochemistry. Furthermore, the response to the TLR4 ligand LPS was stronger in VSMC from RP105(-/- mice resulting in a higher proliferation rate. In RP105(-/- mice femoral artery cuff placement resulted in an increase in neointima formation as compared to WT mice (4982 ± 974 µm(2 vs.1947 ± 278 µm(2,p = 0.0014. Local LPS application augmented neointima formation in both groups, but in RP105(-/- mice this effect was more pronounced (10316±1243 µm(2 vs.4208 ± 555 µm(2,p = 0.0002, suggesting a functional role for RP105. For additional functional studies, the extracellular domain of murine RP105 was expressed with or without its adaptor protein MD1 and purified. SEC-MALSanalysis showed a functional 2∶2 homodimer formation of the RP105-MD1 complex. This protein complex was able to block the TLR4 response in whole blood ex-vivo. In vivo gene transfer of plasmid vectors encoding the extracellular part of RP105 and its adaptor protein MD1 were performed to initiate a stable endogenous soluble protein production. Expression of soluble RP105-MD1 resulted in a significant reduction in neointima formation in hypercholesterolemic mice (2500 ± 573 vs.6581 ± 1894 µm(2,p<0.05, whereas expression of the single factors RP105 or MD1 had no effect. CONCLUSION: RP105 is a potent inhibitor of post-interventional neointima formation.

    The use of Nasal Continuous Positive Airway Pressure Ventilation (NCPAP) has begun to increase and is progressively replacing conventional mechanical ventilation (MV), becoming the cornerstone treatment for newborn respiratory distress syndrome (RDS). However, NCPAP use in Lower-Middle Income Countries (LMICs) is poor. Moreover, bubble NCPAP (bNCPAP), for efficacy, cost effectiveness, and ease of use, should be the primary assistance technique employed in newborns with RDS. To measure the impact on in-hospital newborn mortality of using a bNCPAP device as the first intervention on newborns requiring ventilatory assistance. Prospective pre-intervention and post-intervention study. The largest Neonatal Intensive Care Unit (NICU) in Nicaragua. In all, 230 (2006) and 383 (2008) patients were included. In May 2006, a strategy was introduced to promote the systematic use of bNCPAP to avoid intubation and MV in newborns requiring ventilatory assistance. Data regarding gestation, delivery, postnatal course, mortality, length of hospitalisation, and duration of ventilatory assistance were collected for infants assisted between May and December 2006, before the project began, and between May and December 2008, two years afterwards. The pre- vs post-intervention proportion of newborns who died in-hospital was the primary end point. Secondary endpoints included rate of intubation and duration of NICU stay. Significant differences were found in the rate of intubation (72 vs 39%; p < 0.0001) and the proportion of patients treated exclusively with bNCPAP (27% vs 61%; p <0.0001). Mortality rate was significantly reduced (40 vs 23%; p < 0.0001); however, an increase in the mean duration of NICU stay was observed (14.6 days in 2006 and 17.5 days in 2008, p = 0.0481). The findings contribute to the evidence that NCPAP, particularly bNCPAP, is the first-line standard of care for efficacy, cost effectiveness, and ease of use in newborns with respiratory distress in LMICs.

    The ability to interpret an X-Ray is a vital skill for graduating medical students which guides clinicians towards accurate diagnosis and treatment of the patient. However, research has suggested that radiological interpretation skills are less than satisfactory in not only medical students, but also in residents and consultants. This study investigated the effectiveness of e-learning for the development of X-ray interpretation skills in pre-clinical medical students. Competencies in clinical X-Ray interpretation were assessed by comparison of pre- and post-intervention scores and one year follow up assessment, where the e-learning course was the 'intervention'. Our results demonstrate improved knowledge and skills in X-ray interpretation in students. Assessment of the post training students showed significantly higher scores than the scores of control group of students undertaking the same assessment at the same time. The development of the Internet and advances in multimedia technologies has paved the way for computer-assisted education. As more rural clinical schools are established the electronic delivery of radiology teaching through websites will become a necessity. The use of e-learning to deliver radiology tuition to medical students represents an exciting alternative and is an effective method of developing competency in radiological interpretation for medical students.

    Listening to Mozart K.448 has been demonstrated to improve spatial task scores, leading to what is known as the Mozart Effect. However, most of these reports only describe the phenomena but lack the scientific evidence needed to properly investigate the mechanism of Mozart Effect. In this study, we used electroencephalography (EEG) and heart rate variability (HRV) to evaluate the effects of Mozart K.448 on healthy volunteers to explore Mozart Effect. An EEG-based post-intervention analysis. Kaohsiung Medical University Hospital, Kaohsiung, Taiwan. Twenty-nine college students were enrolled. They received EEG and electrocardiogram examinations simultaneously before, during and after listening to the first movement of Mozart K.448. EEG alpha, theta and beta power and HRV were compared in each stage. The results showed a significant decrease in alpha, theta and beta power when they listened to Mozart K.448. In addition, the average root mean square successive difference, the proportion derived by dividing NN50 by the total number of NN intervals, standard deviations of NN intervals and standard deviations of differences between adjacent NN intervals showed a significant decrease, while the high frequency revealed a significant decrease with a significantly elevated low-frequency/high-frequency ratio. Listening to Mozart K.448 significantly decreased EEG alpha, theta and beta power and HRV. This study indicates that there is brain cortical function and sympathetic tone activation in healthy adults when listening to Mozart K.448, which may play an important role in the mechanism of Mozart Effect.

    Locomotion training in a home visit-type preventive-care program has been reported elsewhere. However, continuation of appropriate exercises in a home setting is difficult, and few reports are available on locomotion training in a home setting. The objective of this study was to evaluate the effectiveness of locomotion training over 3 months in a home visit-type preventive-care program for improvement of motor function among elderly people. Nine hundred and fifty-eight elderly people in Tendo City in Japan who were not currently attending any preventive-care program were invited to participate in the study, and 87 were enrolled. In the pre-intervention and post-intervention assessments, we administered an interview survey (the Kihon Checklist), the timed one-leg standing test with eyes open and the sit-to-stand test, at the participants' homes. The intervention involved one set of training exercises with the participants standing on each leg for 1 min and squatting five or six times. The participants were asked to repeat one set of the exercises three times a day at home. In addition, the participants were regularly asked over the telephone about their performance of the exercises. Physical strength, cognitive function, and total scores of the Kihon Checklist were significantly lower after the intervention than before. In addition, the one-leg standing test time was significantly longer after the intervention (mean ± SD, 23.9 ± 35.4) than before (15.7 ± 20.5), and the sit-to-stand test time was significantly shorter after the intervention (13.0 ± 6.2) than before (14.8 ± 8.3). Locomotion training in a home-visit preventive-care program with telephone support effectively improved the motor function of elderly people who were not currently attending any preventive-care program organized by the long-term care insurance system.

    Maternal and paternal depression has been associated with infants' behavioral sleep problems. Behavioral sleep interventions, which alter parental cognitions about infant sleep, have improved infant sleep problems. This study reports relationships between parental depression, fatigue, sleep quality, and cognitions about infant sleep pre and post-intervention for a behavioral sleep problem. This secondary analysis of data from Canadian parents (n = 455), with healthy infants aged 6-to-8-months exposed to a behavioral sleep intervention, examined baseline data and follow-up data from 18 or 24 weeks post intervention (group teaching or printed material) exposure. Parents reported on sleep quality, fatigue, depression, and cognitions about infant sleep. Data were analyzed using Pearson's r and stepwise regression analysis. Parents' fatigue, sleep quality, sleep cognitions, and depression scores were correlated at baseline and follow-up. At baseline, sleep quality (b = .52, 95% CI .19-.85), fatigue (b = .48, 95% CI .33-.63), doubt about managing infant sleep (b = .44, 95% CI .19-.69), and anger about infant sleep (b = .69, 95% CI .44-.94) were associated with mothers' depression. At baseline, fathers' depression related to sleep quality (b = .42, 95% CI .01-.83), fatigue (b = .47, 95% CI .32-.63), and doubt about managing infant sleep (b = .50, 95% CI .24-.76). At follow-up, mothers' depression was associated with sleep quality (b = .76, 95% CI .41-1.12), fatigue (b = .25, 95% CI .14-.37), doubt about managing infant sleep (b = .44, 95% CI .16-.73), sleep anger (b = .31, 95% CI .02-.59), and setting sleep limits (b = -.22, 95% CI -.41-[-.03]). At follow-up, fathers' depression related to sleep quality (b = .84, 95% CI .46-1.22), fatigue (b = .31, 95% CI .17-.45), sleep doubt (b = .34, 95% CI .05-.62), and setting sleep limits (b = .25, 95% CI .01-.49).

    In 2008-09, the National Health Systems Resource Center of India reported overall quality of nurse-midwifery education in Bihar as grossly sub-optimal. To address this, we implemented a competency-based training using virtual classrooms in two general nurse midwives (GNM) schools of Bihar. The students from remotely located nursing institutions were now able to see live demonstrations of maternal and newborn health (MNH) practices performed by a trained faculty on simulation models at instructor location. To evaluate the effectiveness of virtual classroom training in improving the MNH-related skills of the nursing-midwifery students in Bihar, India. This study used a pre- and post-intervention design without a control group. Students from two public GNM schools of Bihar. Final-year students from both the GNM schools who have completed their coursework in MNH. A total of 83 students from selected GNM schools were assessed for their competencies in six key MNH practices using objective structured clinical examination method prior to intervention. A 72hour standardized training package was then implemented in these schools through virtual classroom approach. Post-intervention, 92 students from the next batch who attended virtual training were assessed for the same competencies. The mean student score assessed before the intervention was 21.3 (95% CI, 19.9-22.6), which increased to 62.0 (95% CI, 60.3-63.7) post-intervention. This difference was statistically significant. When adjusted for clustering using linear regression analysis, the students in post-intervention scored 52.3 (95% CI, 49.4%-55.3%) percentage points higher than pre-intervention, and this was statistically significant. Virtual classroom training was found to be effective in improving knowledge and key MNH skills of GNM students in Bihar, India. Copyright © 2015. Published by Elsevier Ltd.

    Full Text Available OBJECTIVE: to study the changes in health-related quality of life from beginning of anticoagulation therapy to six-month follow-up, and to study associations of sociodemographic and clinical characteristics with measures of quality of life and general health status at six-month follow-up, in individuals using oral anticoagulation due to various medical indications for the therapy. METHOD: prospective study performed at a city in the state of Paraná, Brazil, composed of 78 patients. Measures included the Duke Anticoagulation Satisfaction Scale and the Medical Outcomes Survey Short Form SF-36. RESULTS: mean age was 57 years (S.D.= 16 and 54% were women. Compared to the beginning of therapy, there was a statistically significant improvement in health-related quality of life at six-month follow-up. Linear regression analyses explained 32% and 30%, respectively, of the variance of the Duke Anticoagulation Satisfaction Scale and of the general health status. There was improvement in all components of the SF-36, except Mental Health. CONCLUSION: The use of oral anticoagulation therapy was associated with improvement in health-related quality of life in the first six months of therapy. This study is longitudinal and therefore, has fewer limitations than cross-sectional studies published to date in the Nursing literature in Brazil.OBJETIVO: Estudiar los cambios en la calidad de vida relacionada con la salud desde el inicio de la anticoagulación oral y al final de seis meses de tratamiento, y estudiar las asociaciones de las características sociodemográficas y clínicas con las medidas de calidad de vida y salud general seis meses después de iniciar la terapia, en pacientes con diversas indicaciones clínicas de anticoagulación oral.

    There is limited knowledge as to whether obesity prevention interventions are able to produce change in the determinants hypothesized to precede change in energy balance-related behaviors in young people. The aim of this study was to evaluate the effect of a multi-component intervention on a wide range of theoretically informed determinants of physical activity (PA) and sedentary behavior (SB). Moderation effects of gender, weight status and parental education level and whether the perceived intervention dose received influenced the effects were also explored. The HEIA study was a 20-month school-based, randomized controlled trial to promote healthy weight development. In total, 1418 11-year-olds participated at baseline and post-intervention assessment. Enjoyment, self-efficacy, perceived social support from parents, teachers and friends related to PA, perceived parental regulation of TV-viewing and computer/game-use and perceived social inclusion at schools were examined by covariance analyses to assess overall effects and moderation by gender, weight status and parental education, mid-way and post-intervention. Covariance analyses were also used to examine the role of intervention dose received on change in the determinants. At mid-way enjoyment (p = .03), perceived social support from teachers (p = .003) and self-efficacy (p = .05) were higher in the intervention group. Weight status moderated the effect on self-efficacy, with a positive effect observed among the normal weight only. At post-intervention results were sustained for social support from teachers (p = .001), while a negative effect was found for self-efficacy (p = .02). Weight status moderated the effect on enjoyment, with reduced enjoyment observed among the overweight. Moderation effects for parental education level were detected for perceived social support from parents and teachers. Finally, positive effects on several determinants were observed among those receiving a high

    The two water electrolysis systems used in the NASA space station simulation 90-day manned test of a regenerative life support system were refurbished as required and subjected to 26-weeks of testing. The two electrolysis units are both promising systems for oxygen and hydrogen generation and both needed extensive long-term testing to evaluate the performance of the respective cell design and provide guidance for further development. Testing was conducted to evaluate performance in terms of current, pressure, variable oxygen demands, and orbital simulation. An automatic monitoring system was used to record, monitor and printout performance data at one minute, ten minute or one-hour intervals. Performance data is presented for each day of system operation for each module used during the day. Failures are analyzed, remedial action taken to eliminate problems is discussed and recommendations for redesign for future space applications are stated.

    While imprint training procedures have been promoted in popular magazines, they have received limited scientific investigation. To determine the effects of a neonatal imprint training procedure on 6-month-old foals and to determine if any one session had a greater effect than others. Foals (n = 131) were divided into the following treatments: no imprint training, imprint training at birth, 12, 24 and 48 h after birth or imprint training only at birth, 12, 24, 48, or 72 h after birth. Foals then received minimal human handling until they were tested at 6 months. During training, time to complete exposure to the stimulus was significant for only 2 of 6 stimuli. Percentage change in baseline heart rate was significant for only 2 of 10 stimuli. These 4 effects were randomly spread across treatments. Neither the number of imprint training sessions (0, 1, or 4) nor the timing of imprint training sessions (none, birth, 12, 24, 48, or 72 h after birth) influenced the foal's behaviour at 6 months of age. In this study, imprint training did not result in better behaved, less reactive foals.

    During the first half of 1991, national average gasoline and diesel No. 2 fuel prices declined in many countries in terms of US dollars, due to the stronger US currency and weaker crude oil prices. However, in countries' own currencies, consumer prices were unchanged or higher than they were at the end of 1990. This issue of Energy Detente features findings from their ongoing Fuel Price/Tax Series and closely compares fuel price and tax levels around the world. This issue also presents the following: (1) the ED Refining Netback Data Series for the US Gulf and West Coasts, Rotterdam, and Singapore as of August 23, 1991; and (2) the ED Fuel Price/Tax Series for countries of the Eastern Hemisphere, August 1991 Edition. 6 figs., 11 tabs

    This study investigated the prospective association between supervisor leadership styles and workplace bullying. Altogether 404 civil servants from a local government in Japan completed baseline and follow-up surveys. The leadership variables and exposure to bullying were measured by Multifactor Leadership Questionnaire and Negative Acts Questionnaire-Revised, respectively. The prevalence of workplace bullying was 14.8% at baseline and 15.1% at follow-up. Among respondents who did not experience bullying at baseline (n=216), those who worked under the supervisors as higher in passive laissez-faire leadership had a 4.3 times higher risk of new exposure to bullying. On the other hand, respondents whose supervisors with highly considerate of the individual had a 70% lower risk of new exposure to bullying. In the entire sample (n=317), passive laissez-faire leadership was significantly and positively associated, while charisma/inspiration, individual consideration, and contingent reward were negatively associated both after adjusting for demographic and occupational characteristics at baseline, life events during follow-up, and exposure to workplace bullying at baseline. Results indicated that passive laissez-faire and low individual consideration leadership style at baseline were strong predictors of new exposure to bullying and high individual consideration leadership of supervisors/managers could be a preventive factor against bullying.

    Fall in elderly subject is a main event by its medical and social consequences, but few studies were dedicated to the prognosis from hospitalization in geriatric acute care unit. Describe the outcome of elderly subjects hospitalized after a fall in geriatric acute care unit. Longitudinal study of 6 months follow-up, 100 patients of 75 and more years old hospitalized after a fall in acute care geriatric unit. On a total of 128 patients hospitalized for fall, 100 agreed to participate in the study, 3 died during the hospitalization, so 97 subjects were able to be followed. During 6 months after the hospitalization, 14 patients died (14.9%), 51 (58%) have fallen again (58%) and 11 (22%) of them suffer from severe injuries. Thirty seven (39.7%) were rehospitalized and 10 of them related to fall. Among the patients coming from their home, 25 had been institutionalized. The main risk factor which have been identified to be associated with a new fall during the follow-up was a known dementia at the entry. The medical and social prognosis of an elderly subject hospitalized in an acute care unit is severe. The main comorbidity which influences the medical and social outcome is a known dementia, in addition to a history of previous fall.

    This study analyzed the incidence and characteristics of injuries sustained by amateur youth football players in Portugal during season 2015 - 2016. This is an observational descriptive study. We analyzed Portuguese youth football players' injuries over six months of a season. A total of 529 players were divided according to their age in two groups (Under-17 and Under-19). Data on injuries were collected. Throughout all 62 062.0 hours of exposure recorded, 248 injuries were reported in 173 different players. The average incidence of injury was 3.87 (95% CI = 2.81; 4.94) per 1000 hours of football exposure. There was a significantly higher average incidence of injury during matches - 14.22 (95% CI = 10.35; 18.09) per 1000 hours of exposure - when compared to the average incidence of injury during training - 2.06 (95% CI = 1.22; 2.90) per 1000 hours of exposure. This significance was also observed when the comparison was made within each age group. A traumatic mechanism was involved in 76.6% of all the injuries, while overuse was reported in 12.9%. The most common type was the injury that affected muscles and tendons (52.8%). The body location most commonly affected by injuries was the thigh (24.6%). Even though is essential a better characterization of Portuguese athletes of younger age groups such as those discussed in this study, the results of the studied population are in agreement with the existing literature. However, this study provides more information that may be important to better target the Portuguese athletes' training for injury prevention. This study provides descriptive data on injuries developed in a subpopulation of Portuguese amateur youth football players that could represent a focus for future prevention.

    Recent clinical trials are reporting marked improvements in mental health outcomes with psychedelic drug-assisted psychotherapy. Here, we report on safety and efficacy outcomes for up to 6 months in an open-label trial of psilocybin for treatment-resistant depression. Twenty patients (six females) with (mostly) severe, unipolar, treatment-resistant major depression received two oral doses of psilocybin (10 and 25 mg, 7 days apart) in a supportive setting. Depressive symptoms were assessed from 1 week to 6 months post-treatment, with the self-rated QIDS-SR16 as the primary outcome measure. Treatment was generally well tolerated. Relative to baseline, marked reductions in depressive symptoms were observed for the first 5 weeks post-treatment (Cohen's d = 2.2 at week 1 and 2.3 at week 5, both p psilocybin. Reductions in depressive symptoms at 5 weeks were predicted by the quality of the acute psychedelic experience. Although limited conclusions can be drawn about treatment efficacy from open-label trials, tolerability was good, effect sizes large and symptom improvements appeared rapidly after just two psilocybin treatment sessions and remained significant 6 months post-treatment in a treatment-resistant cohort. Psilocybin represents a promising paradigm for unresponsive depression that warrants further research in double-blind randomised control trials.

    To investigate a Serratia marcescens (S. marcescens) outbreak in a Neonatal Unit in a tertiary university hospital. Descriptive study of children admitted to the Unit with S. marcescens infection from November 2012 to March 2013. Conventional microbiological methods for clinical and environmental samples were used. The clonal relationship between all available isolates was established by molecular methods. A multidisciplinary team was formed, and preventive measures were taken. S. marcescens was isolated from 18 children. The overall attack rate was 12%, and the case fatality rate in the Intensive Care Unit was 23.5%. The most prevalent types of infections were pneumonia (6), conjunctivitis (6), and bloodstream infection (5). Clinical isolates and environmental isolates obtained from an incubator belonged to a unique clone. The clonal relationship between all S. marcescens strains helped us to identify the possible source of the outbreak. Isolation of S. marcescens from stored water in a container, and from the surface of an incubator after cleaning, suggests a possible environmental source as the outbreak origin, which has been perpetuated due to a failure of cleaning methods in the Unit. The strict hygiene and cleaning measures were the main factors that contributed to the end of the outbreak.

    Although spiritual change is hypothesized to contribute to recovery from alcohol dependence, few studies have used prospective data to investigate this hypothesis. Prior studies have also been limited to treatment-seeking and Alcoholics Anonymous (AA) samples. This study included alcohol-dependent individuals, both in treatment and not, to investigate the effect of spiritual and religious (SR) change on subsequent drinking outcomes, independent of AA involvement. Alcoholics (N = 364) were recruited for a panel study from two abstinence-based treatment centers, a moderation drinking program, and untreated individuals from the local community. Quantitative measures of SR change between baseline and 6 months were used to predict 9-month drinking outcomes, controlling for baseline drinking and AA involvement. Significant 6-month changes in 8 of 12 SR measures were found, which included private SR practices, beliefs, daily spiritual experiences, three measures of forgiveness, negative religious coping, and purpose in life. Increases in private SR practices and forgiveness of self were the strongest predictors of improvements in drinking outcomes. Changes in daily spiritual experiences, purpose in life, a general measure of forgiveness, and negative religious coping also predicted favorable drinking outcomes. SR change predicted good drinking outcomes in alcoholics, even when controlling for AA involvement. SR variables, broadly defined, deserve attention in fostering change even among those who do not affiliate with AA or religious institutions. Last, future research should include SR variables, particularly various types of forgiveness, given the strong effects found for forgiveness of self.

Mas nenhuma diferença significante foi encontrada estre as medidas cefalométricas angulares e lineares ao longo dos períodos T0, T1, T2, e T3 e nem quando se comparou essas medidas as do grupo controle (p > 0.05. Conclui-se que A ERM precoce produz aumentos transversais estáveis no arco superior sem alterar significantemente as relações sagitais e verticais dentoesqueléticas e nem inclinar dentes.

    This case history report describes the clinical, radiographic, and histopathologic features of an osteosarcoma with an associated pathologic fracture in a 6-month-old dog. A 6-month-old intact male Bloodhound was presented with a primary complaint of a right forelimb lameness of one month's duration. In radiographs, a minimally displaced transverse fracture of the proximal humeral metaphysis was seen. There was extensive cortical bone destruction at the fracture site and minimal periosteal new bone suggestive of a primary bone tumor with a pathologic fracture. Biopsy specimens demonstrated neoplastic mesenchymal cells producing osteoid compatible with a diagnosis of osteosarcoma. This case history report constitutes the youngest reported canine osteosarcoma

    The disaster of the Sewol ferry that sank at sea off Korea's southern coast of the Yellow Sea on April 16, 2014 was a tragedy that brought grief and despair to the whole country. The aim of this study was to evaluate the mental health effects of this disaster on the community of Ansan, where most victims and survivors resided. The self-administered questionnaire survey was conducted 4 to 6 months after the accident using the Korean Community Health Survey system, an annual nationwide cross-sectional survey. Subjects were 7,076 adults (≥19 years) living in two victimized communities in Ansan, four control communities from Gyeonggi-do, Jindo and Haenam near the accident site. Depression, stress, somatic symptoms, anxiety, and suicidal ideation were measured using the Center for Epidemiologic Studies-Depression Scale, Brief Encounter Psychosocial Instrument, Patient Health Questionnaire-15, and Generalized Anxiety Disorder 7-Item Scale, respectively. The depression rate among the respondents from Ansan was 11.8%, and 18.4% reported suicidal ideation. Prevalence of other psychiatric disturbances was also higher compared with the other areas. A multiple logistic regression analysis revealed significantly higher odds ratios (ORs) in depression (1.66; 95% confidence interval [CI], 1.36 to 2.04), stress (1.37; 95% CI, 1.10 to 1.71), somatic symptoms (1.31; 95% CI, 1.08 to 1.58), anxiety (1.82; 95% CI, 1.39 to 2.39), and suicidal ideation (1.33; 95% CI, 1.13 to 1.56) compared with Gyeonggi-do. In contrast, the accident areas of Jindo and Haenam showed the lowest prevalence and ORs. Residents in the victimized area of Ansan had a significantly higher prevalence of psychiatric disturbances than in the control communities.

    This study investigated the prospective association between supervisor leadership styles and workplace bullying. Altogether 404 civil servants from a local government in Japan completed baseline and follow-up surveys. The leadership variables and exposure to bullying were measured by Multifactor Leadership Questionnaire and Negative Acts Questionnaire-Revised, respectively. The prevalence of workplace bullying was 14.8% at baseline and 15.1% at follow-up. Among respondents who did not experience bullying at baseline (n=216), those who worked under the supervisors as higher in passive laissez-faire leadership had a 4.3 times higher risk of new exposure to bullying. On the other hand, respondents whose supervisors with highly considerate of the individual had a 70% lower risk of new exposure to bullying. In the entire sample (n=317), passive laissez-faire leadership was significantly and positively associated, while charisma/inspiration, individual consideration, and contingent reward were negatively associated both after adjusting for demographic and occupational characteristics at baseline, life events during follow-up, and exposure to workplace bullying at baseline. Results indicated that passive laissez-faire and low individual consideration leadership style at baseline were strong predictors of new exposure to bullying and high individual consideration leadership of supervisors/managers could be a preventive factor against bullying.

    Background Calorie restriction increases longevity in many organisms, and calorie restriction or its mimetic might increase longevity in humans. It is unclear if calorie restriction/dieting contributes to cognitive impairment. During this randomized controlled trial, the effect of 6 months of calorie restriction on cognitive functioning was tested. Methods Participants (n = 48) were randomized to one of four groups: (1) control (weight maintenance), (2) calorie restriction (CR; 25% restriction), (3) CR plus structured exercise (CR + EX, 12.5% restriction plus 12.5% increased energy expenditure via exercise), or (4) low-calorie diet (LCD; 890 kcal/d diet until 15% weight loss, followed by weight maintenance). Cognitive tests (verbal memory, visual memory, attention/concentration) were conducted at baseline and months 3 and 6. Mixed linear models tested if cognitive function changed significantly from baseline to months 3 and 6, and if this change differed by group. Correlation analysis was used to determine if average daily energy deficit (quantified from change in body energy stores) was associated with change in cognitive test performance for the three dieting groups combined. Results No consistent pattern of verbal memory, visual retention/memory, or attention/concentration deficits emerged during the trial. Daily energy deficit was not significantly associated with change in cognitive test performance. Conclusions This randomized controlled trial suggests that calorie restriction/dieting was not associated with a consistent pattern of cognitive impairment. These conclusions must be interpreted in the context of study limitations, namely small sample size and limited statistical power. Previous reports of cognitive impairment might reflect sampling biases or information processing biases. PMID:17518698

    Intentional and unintentional poisoning are among the most common reasons for referrals to emergency department (ED). Therefore, the present study was designed to evaluate epidemiologic features and effective risk factors of intentional and unintentional poisoning in children. This prospective cross-sectional study was carried out in ED of Loghman Hakim Hospital, greatest referral poison center of Iran, Tehran during March to August 2014. Demographic data, medical history, history of psychiatric disease in child, the cause of poisoning, parents' educational level, household monthly income, location of residence, history of addiction or divorce in family, and the poisoning intentionality were gathered. Data were analyzed using SPSS 18 and appropriate statistical tests based on the purpose of study. 414 participants with the mean age of 4.2 ± 3.43 years were included (57.5% male). Children in the 0-4 year(s) age range had the most frequency with 281 (67.9%) cases. 29 (7%) cases were intentional (62% female, 76% in the 10-14 years old group). Methadone with 123 (29.7%) cases was the most frequent toxic agent in general and in unintentional cases. 10-14 years of age (p = 0.001), and the history of psychiatric disease in children (p <0.001), had a direct correlation with probability of intentional poisoning. While, history of addiction in the family showed an indirect correlation with this probability (p = 0.045). Based on the results of this study, most cases of poisoning in the children were unintentional methadone intoxication in boys in the 0-4 age range with a history of a psychiatric disease, and those who had a history of addiction in the family. In addition, the most powerful risk factor for the children's intentional poisoning was their history of psychiatric disease. The history of addiction in the child's family had indirect correlation with intentional intoxications.

    Full Text Available Abstract Addiction should be a matter, primarily, for the Chief of Medicine rather than the Chief of Police. While internationally renowned for its social kindness, Canada has not been without its share of disgraceful political mistakes in the not too distant past. Regrettably, there are many shameful events in Canada that have unfolded in the name of public policy including the banishment without medical treatment of Chinese Canadians living with leprosy to die on D'Arcy and Bentinck Islands in British Columbia while European Canadians stricken similarly enjoyed healthcare on the mainland as well as the eternally haunting treatment of people of aboriginal ancestry who were without full voting privileges in some parts of Canada until 1965 and abandoned to encampments, reserves, that paralleled South African apartheid. In due course, these public policies have come to be understood as horrific in retrospect. Many have all met with a remorseful fate where a future Prime Minister is held to public account for the sad excesses of an earlier generation. With respect to North America's only supervised injection facility (SIF, a medical program aimed at reducing fatal overdoses and infections (HIV, HCV in injection drug users, Canada's Prime Minister Stephen Harper holds the ability to forestall a similarly heartrending fate in his political hands. The SIF currently has a temporary exemption from Canada's "Controlled Drugs and Substances Act" in order to operate until June of 2008. As such, the fate of the SIF is politically determined each time behind closed doors by the Prime Minister and his ministers. Sadly, the Prime Minister appears lost at present, content to ignore the scientific and medical evidence on the matter of population health. In light of the vast medical evidence accumulated on Vancouver's SIF, the fate of injection facilities needs to be taken out of the political realm entirely. I am hoping that the Prime Minister will be found, see the light of the scientific evidence, and lead the way towards to provision of a permanent medical exemption for injection facilities from Canada's Controlled Drugs and Substances Act (CDSA. In so doing, the Prime Minister would be on the brink of grace and would rescue a life saving health program from perpetual political interference.

    Cardiovascular complications in the postoperative period are associated with high mortality and morbidity. Few studies have assessed the degree of dependence in these patients and their perception of health. The objective of this study was to assess the mortality and the quality of life in patients who developed major cardiac events (MCE) in the postoperative period. Retrospective study carried out in a Surgical Intensive Care Unit (SICU), between March 2006 and March 2008. The patients were assessed regarding the occurrence of CE. Six months after the hospital discharge, the Short-Form-36 (SF-36) questionnaire was filled out and dependence was assessed in relation to activities of daily living (ADL). The comparisons between independent groups of patients were carried out using Student's t test. The comparison between each variable and the occurrence of CE was carried out by logistic regression and included all patients. Of the 1,280 patients that met the inclusion criteria, 26 (2%) developed MCE. The univariate analysis identified as independent determinants for the development of major cardiac events: ASA physical status, hypertension, ischemic heart disease, congestive heart disease and score of the Revised Cardiac Risk Index (RCRI). The six-month mortality after the SICU discharge was 35%. Of the 17 surviving patients, 13 completed the questionnaires. Thirty-one percent of them reported that their general health was better on the day they answered the questionnaire, when compared to 12 months before. Sixty-nine percent of the patients were dependent in instrumental ADL e 15% in personal ADL. The development of MCE has a significant impact on the duration of hospital stay and mortality rates. Six months after the discharge from the SICU, more than 50% of the patients were dependent in at least one instrumental ADL. Copyright 2010 Elsevier Editora Ltda. All rights reserved.

    The effect of the gamma radiation on the preservation of potato tubers stored during a period of six months is described by evaluating the loss by sprouting, transpiration and infections. The dose of 9 Krad inhibits sprouting with independence of the epoch in wich the treatment is made, on the other hand a dose of 6 Krad inhibits sprouting only if the tubers are irradiated during the resting period. The treatment with IPC gave similar results to those obtained with a dose of 9 Krad. (author) [es

    Periodical cicadas (Magicicada spp.) in the USA are famous for their unique prime-numbered life cycles of 13 and 17 years and their nearly perfectly synchronized mass emergences. Because almost all known species of cicada are non-periodical, periodicity is assumed to be a derived state. A leading hypothesis for the evolution of periodicity in Magicicada implicates the decline in average temperature during glacial periods. During the evolution of periodicity, the determinant of maturation in ancestral cicadas is hypothesized to have switched from size dependence to time (period) dependence. The selection for the prime-numbered cycles should have taken place only after the fixation of periodicity. Here, we build an individual-based model of cicadas under conditions of climatic cooling to explore the fixation of periodicity. In our model, under cold environments, extremely long juvenile stages lead to extremely low adult densities, limiting mating opportunities and favouring the evolution of synchronized emergence. Our results indicate that these changes, which were triggered by glacial cooling, could have led to the fixation of periodicity in the non-periodical ancestors.

    The chemical elements present in the modern periodic table are arranged in terms of atomic numbers and chemical periodicity. Periodicity arises from quantum mechanical limitations on how many electrons can occupy various shells and subshells of an atom. The shell model of the atom predicts that a maximum of 2, 8, 18, and 32 electrons can occupy…

  12. Periods and Nori motives

    CERN Document Server

    Huber, Annette

    2017-01-01

    This book casts the theory of periods of algebraic varieties in the natural setting of Madhav Nori’s abelian category of mixed motives. It develops Nori’s approach to mixed motives from scratch, thereby filling an important gap in the literature, and then explains the connection of mixed motives to periods, including a detailed account of the theory of period numbers in the sense of Kontsevich-Zagier and their structural properties. Period numbers are central to number theory and algebraic geometry, and also play an important role in other fields such as mathematical physics. There are long-standing conjectures about their transcendence properties, best understood in the language of cohomology of algebraic varieties or, more generally, motives. Readers of this book will discover that Nori’s unconditional construction of an abelian category of motives (over fields embeddable into the complex numbers) is particularly well suited for this purpose. Notably, Kontsevich's formal period algebra represents a to...

This extends to n-variables the work of L. Schwartz on mean-periodicity and also extends L. Ehrenpreis' work on partial differential equations with constant coefficients to arbitrary convolutors. We also answer a number of open questions about mean-periodic functions of one variable. The basic ingredient is our work on interpolation by entire functions in one and several complex variables.

  16. Super periodic potential

    Hasan, Mohammd; Mandal, Bhabani Prasad

    2018-04-01

    In this paper we introduce the concept of super periodic potential (SPP) of arbitrary order n, n ∈I+, in one dimension. General theory of wave propagation through SPP of order n is presented and the reflection and transmission coefficients are derived in their closed analytical form by transfer matrix formulation. We present scattering features of super periodic rectangular potential and super periodic delta potential as special cases of SPP. It is found that the symmetric self-similarity is the special case of super periodicity. Thus by identifying a symmetric fractal potential as special cases of SPP, one can obtain the tunnelling amplitude for a particle from such fractal potential. By using the formalism of SPP we obtain the close form expression of tunnelling amplitude of a particle for general Cantor and Smith-Volterra-Cantor potentials.

    The higher order supersymmetric partners of a stationary periodic potential are studied. The transformation functions associated to the band edges do not change the spectral structure. However, when the transformation is implemented for factorization energies inside of the forbidden bands, the final potential will have again the initial band structure but it can have bound states encrusted into the gaps, giving place to localized periodicity defects.

    Maria ARREGUI

    Full Text Available Abstract Color match and water sorption are two factors that affect restorative materials. Discoloration is essential in the lifespan of restorations. The aim of this study was to evaluate color change and water sorption of nine flowable composites at multiple time points over 6 months. 60 samples of each composite were divided into two groups (Color Change and Water Sorption/Solubility. Each Color Change group was divided into six subgroups, which were immersed in distilled water (DW, coffee (CF, Coca-Cola (CC, red wine (RW, tea (TE and orange juice (OJ. The color was measured at the baseline, 1, 2, 3 and 4 weeks, and 3 and 6 months and color change values (ΔE were calculated. Each Water Sorption [WS]/Solubility [WL] group was tested according to ISO 4049:2009. The data were evaluated using two-way ANOVA, Fisher’s post-hoc test and Pearson’s correlation test. The composite with the lowest ΔE differed for each solution: Filtek™ Bulk Fill in DW (∆E = 0.73 (0.17–1.759; Vertise Flow in CF (∆E = 14.75 (7.91–27.41, in TE (∆E = 7.27 (2.81–24.81 and OJ (∆E = 3.17 (0.87–9.92; Tetric EvoFlow® in CC (∆E = 1.27 (0.45–4.02; and Filtek™ Supreme XTE in RW (∆E = 8.88 (5.23–19.59. RW caused the most discoloration (∆E = 23.62 (4.93–51.36. Vertise Flow showed the highest water sorption (WS = 69.10 ± 7.19. The Pearson test showed statistically significant positive correlations between water sorption and solubility and between water sorption and ∆E; the positive solubility-∆E correlation was not statistically significant. The findings suggest that water sorption is one factor associated with the ability of composites to discolor; however, discoloration is a multifactorial problem.

    Marijuana addiction is one of the most common forms of addiction worldwide. A variety of reasons for use exist, however, there are only a few tested treatments with frequent relapses. In this study, we examined the efficacy of four pharmacotherapy agents for the treatment of marijuana addiction: naltrexone, bupropion, escitalopram and bromazepam. A total of 59 patients were randomly assigned into four groups. Each group received one of the pharmacological agents for 120 days. Four types of questionnaires were employed: The Hamilton Rating Scale for Depression--21 items, the Hamilton Rating Scale for Anxiety, the Global Assessment of Functioning and a Visual Analogue Scale for perceived need of the drug. In addition, random urine tests were performed to detect tetrahydrocannabinol [THC). Naltrexone proved to be the most efficacious of the four agents, with only four dropouts. Other agents proved less efficacious with six, seven and eights dropouts for bupropion, bromazepam and escitalopram, respectively. In addition, naltrexone was most efficacious in reducing anxiety and depression rates, and increasing functioning and perceived need for drug use. Out of four pharmacological agents, naltrexone proved to be most efficacious in treating marijuana addiction and related disorders. Further studies are needed to confirm our results.

    Objective To evaluate prospectively the impact of fluorodeoxyglucose-fluorine-18 positron emission tomography (FDG-PET) in the detection of recurrence, second primary cancers, and distant metastases in head and neck squamous cell carcinoma (HNSCC) 6 months after treatment. Methods A total of 41 patients without any clinical element for recurrence, second primary cancer, or distant metastases received a whole-body FDG-PET as a routine surveillance tool 6 months after initial combined curative therapy for HNSCC. Results There were 35 negative PET results and 6 positive. One patient with abnormal FDG-PET did not have recurrent HNSCC (false positive). Five had true positive results: proven recurrence in 2 patients, second primary cancer in 2, and distant metastasis in 1. The sensitivity and specificity of FDG-PET for the diagnosis of HNSCC recurrence, second tumor, and distant metastases were 100% (5/5) and 97.2% (35/36), respectively. The positive predictive value was 83.3% (5/6). The negative predictive value was 100% (35/35). The overall accuracy was 97.6% (40/41). FDG-PET had a therapeutic impact in 5 of 41 patients (12.2%). There was no impact of FDG-PET on management in other 36 patients. Conclusion FDG-PET is useful as primary method for detecting nodal recurrence and distant metastases in HNSCC as well as second cancer in subclinical patients as it had a high effectiveness. But systematic FDG-PET performed at 6 months in patients without any clinical suspicion of local recurrence was scarcely useful.

    Severe tricuspid regurgitation (TR) is common in patients with right-sided heart failure (HF) and causes substantial morbidity and mortality. Treatment options beyond medical therapy are limited for high-risk patients. Transcatheter edge-to-edge tricuspid valve (TV) repair showed procedural safety and short-term efficacy. Impact on mid-term outcome is unclear. This dual-centre observational study evaluates the mid-term safety, efficacy and clinical outcome after edge-to-edge TV repair for severe TR in patients with HF. Overall, 50 patients with right-sided HF and severe TR were treated with the transcatheter edge-to-edge repair technique; 14 patients were treated for isolated TR and 36 patients for combined mitral regurgitation (MR) and TR. At 6-month follow-up (available for 98% of patients), a persistent reduction of at least one echocardiographic TR grade was achieved in 90% of patients and New York Heart Association class improved in 79% of patients. The 6-minute walk distance increased by 44% (+84 m, P edge-to-edge TV repair for severe TR is safe and effective in reducing TR. It appears to be associated with improved clinical outcome in the majority of patients. © 2018 The Authors. European Journal of Heart Failure © 2018 European Society of Cardiology.

    Objective To measure stigma associated with four types of postpartum depression therapies and to estimate the association between stigma and the acceptance of these therapies for black and white postpartum mothers. Methods Using data from two postpartum depression randomized trials, this study included 481 black and white women who gave birth in a large urban hospital and answered a series of questions at 6-months postpartum. Survey items included socio demographic and clinical factors, attitudes about postpartum depression therapies and stigma. The associations between race, stigma, and treatment acceptability were examined using bivariate and multivariate analyses. Results Black postpartum mothers were less likely than whites to accept prescription medication (64 vs. 81%, p = 0.0001) and mental health counseling (87 vs. 93%, p = 0.001) and more likely to accept spiritual counseling (70 vs. 52%, p = 0.0002). Women who endorsed stigma about receipt of postpartum depression therapies versus those who did not were less likely to accept prescription medication, mental health and spiritual counseling for postpartum depression. Overall black mothers were less likely to report stigma associated with postpartum depression therapies. In adjusted models, black women versus white women remained less likely to accept prescription medication for postpartum depression (OR = 0.42, 95% CI 0.24-0.72) and stigma did not explain this difference. Conclusions Although treatment stigma is associated with lower postpartum depression treatment acceptance, stigma does not explain the lower levels of postpartum depression treatment acceptance among black women. More research is needed to understand treatment barriers for postpartum depression, especially among black women.

    Full Text Available Ipek Suzer Gamli,1 Aysegul Yolga Tahiroglu2 1Sanliurfa Education and Research Hospital, Eyyubiye, Sanliurfa, Turkey; 2Child and Adolescent Psychiatry Department, Cukurova University School of Medicine, Saricam, Adana, Turkey Purpose: Individuals with attention deficit/hyperactivity disorder (ADHD may suffer from emotional dysregulation (ED, although this symptom is not listed among the diagnostic criteria. Methylphenidate (MPH is useful in reducing emotional symptoms in ADHD. The aim of the present study was to determine both psychosocial risk factors and presence of ED in adolescents with ADHD before and after MPH treatment. Participants and methods: Eighty-two patients aged 12–18 years with ADHD were included as participants. The Kiddie Schedule for Affective Disorders and Schizophrenia for School-Age Children – Present and Lifetime, the Difficulties in Emotion Regulation Scale (DERS, sociodemographic form, and the Inventory of Statements About Self-Injury were administered. Results were compared before and after 6 months MPH treatment. Results: A significant improvement was detected on DERS for impulsivity (15.9±6.8 initial vs 14.2±6.5 final test, p<0.01 and total score (88.4±23.3 initial vs 82.4±2.7 final test, p<0.05 across all patients taking MPH regardless of subtype and sex. Despite treatment, a significant difference remained for impulsivity, strategies, and total score in patients with comorbid oppositional defiant disorder (ODD compared with those without ODD, but no difference was detected for conduct disorder comorbidity. In patients who self-harm, scores for goals, impulsivity, strategies, clarity, and total score were higher before treatment: furthermore, impulsivity and total score remained high after treatment. In maltreated patients, goals, impulsivity, strategies, and total scores were significantly higher before treatment; however, their symptoms were ameliorated after treatment with MPH. Conclusion: Individuals with severe ED may “self-medicate” by smoking and/or self-harming. MPH led to significant improvements in ED possibly owing, in part, to a decrease in impulsivity, so that individuals felt more able to supervise their emotions and engage in goal-directed behaviors. ED should be considered particularly in patients with additional psychosocial factors and ODD comorbidity, and included in the treatment plan.

    To evaluate the efficacy of oral chicken type II collagen (CII) in the treatment of rheumatoid arthritis (RA). Sixty patients with clinically active RA of long duration (mean 7.2 +/- 5.5 years) were treated for 6 months with oral chicken CII at 0.25 mg/day (n = 31) or with placebo (n = 29) in a double-blind randomized study. The response rate to treatment of the collagen-treated group, based on the ACR 20% criteria, was higher than that of the control group but this difference was not statistically significant at any time. Intention-to-treat (ITT) analysis did not show statistically significant improvement in any of the several secondary outcome measures over the 6 months of the study in the collagen-treated patients in comparison with the placebo-treated group. However, in 2 collagen-treated patients we observed a clinical remission according to the criteria of the American Rheumatism Association. Our study seems to show that the oral treatment of RA patients with chicken CII is ineffective and results in only small and inconsistent benefits. Furthermore, our results raise the possibility that in a sub-group of patients oral collagen administration, usually considered devoid of harmful effects, may actually induce disease flares.

    2014-01-01

    Corrow, Granrud, Mathison, and Yonas (2011, Perception, 40, 1376-1383) found evidence that 6-month-old infants perceive the hollow face illusion. In the present study we asked whether 6-month-old infants perceive illusory depth reversal for a nonface object and whether infants' perception of the hollow face illusion is affected by mask orientation inversion. In experiment 1 infants viewed a concave bowl, and their reaches were recorded under monocular and binocular viewing conditions. Infants reached to the bowl as if it were convex significantly more often in the monocular than in the binocular viewing condition. These results suggest that infants perceive illusory depth reversal with a nonface stimulus and that the infant visual system has a bias to perceive objects as convex. Infants in experiment 2 viewed a concave face-like mask in upright and inverted orientations. Infants reached to the display as if it were convex more in the monocular than in the binocular condition; however, mask orientation had no effect on reaching. Previous findings that adults' perception of the hollow face illusion is affected by mask orientation inversion have been interpreted as evidence of stored-knowledge influences on perception. However, we found no evidence of such influences in infants, suggesting that their perception of this illusion may not be affected by stored knowledge, and that perceived depth reversal is not face-specific in infants.

  16. Preschool Children’s Memory for Word Forms Remains Stable Over Several Days, but Gradually Decreases after Six Months

    Directory of Open Access Journals (Sweden)

    Katherine Ruth Gordon

    2016-09-01

    Full Text Available Research on word learning has focused on children’s ability to identify a target object when given the word form after a minimal number of exposures to novel word-object pairings. However, relatively little research has focused on children’s ability to retrieve the word form when given the target object. The exceptions involve asking children to recall and produce forms, and children typically perform near floor on these measures. In the current study, 3- to 5-year-old children were administered a novel test of word form that allowed for recognition memory and manual responses. Specifically, when asked to label a previously trained object, children were given three forms to choose from: the target, a minimally different form, and a maximally different form. Children demonstrated memory for word forms at three post-training delays: 10 minutes (short-term, 2 to 3 days (long-term, and 6 months to 1 year (very long-term. However, children performed worse at the very long-term delay than the other time points, and the length of the very long-term delay was negatively related to performance. When in error, children were no more likely to select the minimally different form than the maximally different form at all time points. Overall, these results suggest that children remember word forms that are linked to objects over extended post-training intervals, but that their memory for the forms gradually decreases over time without further exposures. Furthermore, memory traces for word forms do not become less phonologically specific over time; rather children either identify the correct form, or they perform at chance.

    Some studies suggest a relationship between maternal smoking during pregnancy and not only intrauterine fetal growth restriction or low birth weight, but also with changes in the postnatal growth and development. The objective of the present study was to investigate the effects of smoking during pregnancy on infants growth in the first 6 months of life compared with a control group and a group with idiopathic intrauterine growth restriction. Longitudinal observational study using a convenience sample of newborns divided into three groups: infants of smoking mothers (tobacco), with idiopathic intrauterine growth restriction (IUGR) and a control group. The sample was selected from two hospitals in Porto Alegre, located in southern Brazil, between 2011 and 2015. Newborns were evaluated at birth, 7 and 15 days, and in the first, third, and sixth month. Anthropometric measures were weight, length and head circumference. The growth indicators used were expressed as z-scores. The analyses were performed using the generalized estimating equation method. The sample included 273 mother/newborn pairs: 86 tobacco group, 34 IUGR group, and 153 control group. In terms of weight at birth, all groups differed significantly (p < 0.001). The birth length of tobacco and control groups were similar, but the IUGR group was lower than both (p < 0.001). We found no differences in growth trajectory between tobacco and control group, but there were differences in the growth of the IUGR group when compared with the other groups. At 6 months of age, all groups had similar anthropometric measurements. Intrauterine growth restriction had major impact on the growth trajectory of the infants studied, regardless of other factors, such as smoking and diet.

  18. Comparison of peritoneal transport characteristics at the second week and at six months of peritoneal dialysis commencement

    Full Text Available Peritoneal equilibration test (PET is an important tool for managing peritoneal dialysis (PD prescription. The Kidney Disease Outcomes Quality Initiative (KDOQI guidelines suggest that the first PET be performed 4-8 weeks after PD commencement. The main reason for this delay is because of the peritoneal membrane might change its character once it is exposed to the glucose based dialysate. In this study, we compared PET 2 weeks after PD commencement to PET after 6 months to evaluate the changes in the peritoneal membrane character with time. This study included 126 patients who underwent PD initiation between March 2007 and December 2011. The PET was performed as per the standard protocol at 2 nd week and 6 th month after PD initiation. Transport status was categorized as low, low average, high average, and high as per the standard definition. There was no change in transport character in 115 patients (91.2% between the two PET measurements. When the Early PET at 2 nd week and 6 th month PET data were analyzed, no significant changes were observed in measured D/P creatinine (0.59 ± 0.14 vs. 0.62 ± 0.14 respectively P = 0.26 and D/D0 Glucose (0.46 ± 0.12 vs. 0.46 ± 0.11, P = 0.65. Using the Bland-Altman analysis the repeatability coefficients were 0.27 and 0.25 for creatinine and glucose values respectively. In our study, the PET performed at the 2 nd week are similar to that of the 6 th month PET in 91.2% of our patients and the test did not significantly change with time. In conclusion, we could do PET early at 2 nd week to assess the peritoneal membrane character and this would help in proper dialysis prescription to the patients.

    Peritoneal equilibration test (PET) is an important tool for managing peritoneal dialysis (PD) prescription. The Kidney Disease Outcomes Quality Initiative (KDOQI) guidelines suggest that the first PET be performed 4-8 weeks after PD commencement. The main reason for this delay is because of the peritoneal membrane might change its character once it is exposed to the glucose based dialysate. In this study, we compared PET 2 weeks after PD commencement to PET after 6 months to evaluate the changes in the peritoneal membrane character with time. This study included 126 patients who underwent PD initiation between March 2007 and December 2011. The PET was performed as per the standard protocol at 2(nd) week and 6(th) month after PD initiation. Transport status was categorized as low, low average, high average, and high as per the standard definition. There was no change in transport character in 115 patients (91.2%) between the two PET measurements. When the Early PET at 2(nd) week and 6(th) month PET data were analyzed, no significant changes were observed in measured D/P creatinine (0.59 ± 0.14 vs. 0.62 ± 0.14 respectively P = 0.26) and D/D0 Glucose (0.46 ± 0.12 vs. 0.46 ± 0.11, P = 0.65). Using the Bland-Altman analysis the repeatability coefficients were 0.27 and 0.25 for creatinine and glucose values respectively. In our study, the PET performed at the 2(nd) week are similar to that of the 6(th) month PET in 91.2% of our patients and the test did not significantly change with time. In conclusion, we could do PET early at 2(nd) week to assess the peritoneal membrane character and this would help in proper dialysis prescription to the patients.

    During aging, sensorimotor, cognitive and physical performance decline, but can improve by training and exercise indicating that age-related changes are treatable. Dancing is increasingly used as an intervention because it combines many diverse features making it a promising neuroplasticity-inducing tool. We here investigated the effects of a 6-month dance class (1 h/week) on a group of healthy elderly individuals compared to a matched control group (CG). We performed a broad assessment covering cognition, intelligence, attention, reaction time, motor, tactile, and postural performance, as well as subjective well-being and cardio-respiratory performance. After 6 months, in the CG no changes, or further degradation of performance was found. In the dance group, beneficial effects were found for dance-related parameters such as posture and reaction times, but also for cognitive, tactile, motor performance, and subjective well-being. These effects developed without alterations in the cardio-respiratory performance. Correlation of baseline performance with the improvement following intervention revealed that those individuals, who benefitted most from the intervention, were those who showed the lowest performance prior to the intervention. Our findings corroborate previous observations that dancing evokes widespread positive effects. The pre-post design used in the present study implies that the efficacy of dance is most likely not based on a selection bias of particularly gifted individuals. The lack of changes of cardio-respiratory fitness indicates that even moderate levels of physical activity can in combination with rich sensorimotor, cognitive, social, and emotional challenges act to ameliorate a wide spectrum of age-related decline.

    In the United Kingdom patient-reported outcome measures (PROMS) have been adopted as a key measure of foot surgery outcomes. The intention of this study was to evaluate the responsiveness of a regional outcome measure; the Manchester Oxford Foot Questionnaire (MOXFQ) and a generic measure; the EuroQol EQ-5D, in the context of day care Podiatric Surgery. A prospective audit of 375 consecutive day care surgical admissions was undertaken. All patients attending for surgery, who agreed to participate, were included. Pre operation patients completed the MOXFQ and the EQ-5D. Both questionnaires were completed again at 6 months post operation. Additional data was collected on patient demographics, surgical procedures and complications. Few complications were encountered and most patients (84%) returned for a final review 6 months post operation. Mean MOXFQ scores improved for each domain: pain; 51.7 pre-operation, reduced to 16.5 post-operation, walking; 50.2 reduced to 14.1 and social interaction; 45.7 reduced to 10.6. The minimal clinically important differences (MCID) estimates for the pain domain were exceeded by 82.6% of patients, while 74.8% exceeded the MCID for walking and 68.5% exceeded the MCID for social interaction. A small number of patients (2.9%) deteriorated across all three MOXFQ domains.The EQ-5D Index, summary of health related quality of life, improved from 0.66 pre-operation to 0.86 post operation. The EQ-5D index MCID was exceeded by 79.2% of patients. Index scores deteriorated for 1.8% of patients following surgery. Effect sizes measured following surgery were largest for the MOXFQ domains: Walking; 1.39, Pain; 1.52 and Social Interaction: 1.39. The EQ-5D index effect size was 0.83. The EQ-5D visual analogue scale (VAS) was not influenced by surgery. Both the MOXFQ and EQ-5D index (but not the VAS) appear sensitive to changes in health status at 6 months following elective foot surgery. Both instruments were particularly responsive to changes in pain, mobility and activity or social interaction following treatment. The MOXFQ was developed specifically for foot surgery and as such appears to be the more sensitive instrument. However the generic EQ-5D may allow comparison of general health states in the wider health community. Both instruments when used together appear well suited to the measurement of change in perceived health status following foot surgery.

    This study evaluated a novel drug abuse treatment, the Therapeutic Workplace. In this treatment, patients are paid to perform jobs or to participate in job training. Salary is linked to abstinence by requiring patients to provide drug-free urine samples to gain access to the workplace. Pregnant and postpartum drug abuse patients (N = 40) were randomly assigned to a Therapeutic Workplace or usual care control group. Therapeutic Workplace participants were invited to work 3 hr every weekday for 6 months and could earn up to $4,030 in vouchers for abstinence, workplace attendance, and performance. On average, 45% of participants attended the workplace per day. Relative to controls, the Therapeutic Workplace nearly doubled patients' abstinence from opiates and cocaine (33% vs. 59% of thrice-weekly urine samples drug negative, respectively, p Workplace can effectively treat heroin and cocaine abuse in pregnant and postpartum women.

    No effective pharmacotherapies exist for cocaine dependence, although contingency management (CM) has demonstrated efficacy. To compare the efficacy of bupropion hydrochloride and CM for reducing cocaine use in methadone hydrochloride-maintained individuals. This 25-week, placebo-controlled, double-blind trial randomly assigned participants to 1 of 4 treatment conditions: CM and placebo (CMP), CM and 300 mg/d of bupropion hydrochloride (CMB), voucher control and placebo (VCP), or voucher control and bupropion (VCB). Outpatient clinic at the Veterans Affairs Connecticut Healthcare System. A total of 106 opiate-dependent, cocaine-abusing individuals. All study participants received methadone hydrochloride (range, 60-120 mg). Participants receiving bupropion hydrochloride were given 300 mg/d beginning at week 3. In the CM conditions, each urine sample negative for both opioids and cocaine resulted in a monetary-based voucher that increased for consecutively drug-free urine samples during weeks 1 to 13. Completion of abstinence-related activities also resulted in a voucher. During weeks 14 to 25, only completion of activities was reinforced in the CM group, regardless of sample results. The voucher control groups received vouchers for submitting urine samples, regardless of results, throughout the study. Thrice-weekly urine toxicologic test results for cocaine and heroin. Groups did not differ in baseline characteristics or retention rates. Opiate use decreased significantly, with all treatment groups attaining equivalent amounts of opiate use at the end of the study. In the CMB group, the proportion of cocaine-positive samples significantly decreased during weeks 3 to 13 (P<.001) relative to week 3 and remained low during weeks 14 to 25. In the CMP group, cocaine use significantly increased during weeks 3 to 13 (P<.001) relative to week 3, but then cocaine use significantly decreased relative to the initial slope during weeks 14 to 25 (P<.001). In contrast, by treatment end, the VCB and VCP groups showed no significant improvement in cocaine use. These findings suggest that combining CM with bupropion for the treatment of cocaine addiction may significantly improve outcomes relative to bupropion alone.

    Full Text Available Abstract Background Functional Bowel Disorders (FBD are chronic disorders that are difficult to treat and manage. Many patients and doctors are dissatisfied with the level of improvement in symptoms that can be achieved with standard medical care which may lead them to seek alternatives for care. There are currently no data on the types of Complementary and Alternative Medicine (CAM used for FBDs other than Irritable Bowel Syndrome (IBS, or on the economic costs of CAM treatments. The aim of this study is to determine prevalence, types and costs of CAM in IBS, functional diarrhea, functional constipation, and functional abdominal pain. Methods 1012 Patients with FBD were recruited through a health care maintenance organization and followed for 6 months. Questionnaires were used to ascertain: Utilization and expenditures on CAM, symptom severity (IBS-SS, quality of life (IBS-QoL, psychological distress (BSI and perceived treatment effectiveness. Costs for conventional medical care were extracted from administrative claims. Results CAM was used by 35% of patients, at a median yearly cost of $200. The most common CAM types were ginger, massage therapy and yoga. CAM use was associated with female gender, higher education, and anxiety. Satisfaction with physician care and perceived effectiveness of prescription medication were not associated with CAM use. Physician referral to a CAM provider was uncommon but the majority of patients receiving this recommendation followed their physician's advice. Conclusion CAM is used by one-third of FBD patients. CAM use does not seem to be driven by dissatisfaction with conventional care. Physicians should discuss CAM use and effectiveness with their patients and refer patients if appropriate.

    To identify what pharmacy students learn during the 6-month advanced pharmacy practice experience (APPE) in Sweden. Semi-structured interviews were conducted with 18 pharmacy APPE students and 17 pharmacist preceptors and analyzed in a qualitative directed content analysis using a defined workplace learning typology for categories. The Swedish APPE provides students with task performance skills for work at pharmacies and social and professional knowledge, such as teamwork, how to learn while in a work setting, self-evaluation, understanding of the pharmacist role, and decision making and problem solving skills. Many of these skills and knowledge are not accounted for in the curricula in Sweden. Using a workplace learning typology to identify learning outcomes, as in this study, could be useful for curricula development. Exploring the learning that takes place during the APPE in a pharmacy revealed a broad range of skills and knowledge that students acquire.

    Resveratrol (RVTL) is a flavonoid found in red wine and has been publicized heavily as an anti-aging compound. Indeed, basic research confirms that although there is much hype in the promotion of RVTL, flavonoids such as RVTL have a wide range of biological effects. We here investigated the effects of RVTL treatment on hippocampal plasticity and memory performance in female Balb/C mice, a strain with low baseline levels of adult neurogenesis. Two weeks of treatment with RVTL (40 mg/kg) induced the production of new neurons in vivo by increasing cell survival and possibly precursor cell proliferation. In addition, RVTL decreased the number of apoptotic cells. The number of doublecortin (DCX)-expressing intermediate cells was increased. RVTL stimulated neuronal differentiation in vitro without effects on proliferation. In the dentate gyrus, RVTL promoted the formation and maturation of spines on granule cell dendrites. RVTL also improved performance in the step down passive avoidance test. The RVTL-treated mice showed increase in the levels of two key signaling proteins, phospho-Akt and phospho-PKC, suggesting the involvement of these signaling pathways. Our results support the vision that flavonoids such as resveratrol deserve further examination as plasticity-inducing compounds in the context of successful cognitive aging.

    This study assesses the initiation and duration of exclusive/almost exclusive breastfeeding (Ex/AEx-BF) versus partial breastfeeding (P-BF) and its relationship to infant growth and maternal body mass index (BMI) in Ethiopian infants up to 12 months of age (Tigray n = 471; Gonder n =596). Initiation of breastfeeding within 1 hr after birth was 1.7 times more common in Tigray. In Gonder 19% of the mothers started breastfeeding on the third day of delivery and consequently, a significant higher proportion of newborns were offered prelacteal feeds (Phigher in both regions compared to the Ex/AEx-BF group (in Gonder 25% vs 5.9%; in Tigray 42.9% vs 33.3%). Nutrition education to raise awareness of mothers regarding initiation of exclusive breastfeeding directly after birth, the value of colostrum and avoidance of pre-postlacteal feeds, needs to be implemented. A new health package to be implemented could be a proper vehicle to reach the rural population, which doesn't have access to health services. The relationship between infant growth, mode of feeding and mothers nutritional status should be further investigated, particularly in populations with a high prevalence of maternal and infant nutrition and where long term breastfeeding is practiced.

    The 6-month exclusive breastfeeding rate in the Northeast region of Thailand has recently significantly decreased in contrast to all other regions in Thailand. The factors that have influenced this decrease remain unknown. Hence, it is suggested that an investigation into factors that could improve or hinder EBF for 6 months in Northeast Thailand may be required to inform the development of relevant interventions to improve this situation. This study aimed to identify perceived facilitators and barriers to providing exclusive breastfeeding for 6 months in Northeast Thailand among breastfeeding mothers. Six focus group discussions were conducted with a total of 30 mothers aged 20 to 40 years who had children aged between 4 and 6 months and were currently breastfeeding or had breastfeeding experience. Participants were recruited through self-selection sampling from Khonkaen hospital (urban), Numphong hospital (peri-urban) and private hospitals (urban) in Khonkaen, Thailand. Thematic analysis was employed to analyse the data. Five main themes, with 10 sub-themes, were identified as either facilitators (+) or barriers (-), or in some cases, as both (+/-). Breastfeeding knowledge, perceptions, maternal circumstances, support, and traditional food were the main identified themes. Mother's breastfeeding knowledge, intention to breastfeed, and social media were perceived as facilitators. Perceptions, employment, and formula milk promotion were perceived as barriers. Family, healthcare, and traditional food were perceived as both facilitators and barriers. The perception that social media was a way to access breastfeeding knowledge and support mothers in Northeast Thailand emerged as a new facilitating factor that had not previously been identified in Thai literature relating to facilitators and barriers to exclusive breastfeeding. Intention to breastfeed, family support, healthcare support and traditional food were mentioned by all groups, whereas mothers from urban areas specifically mentioned mother's breastfeeding knowledge, social media and employment sub-themes. Only mothers from the peri-urban area mentioned formula milk promotion and only mothers who had delivered in public hospitals mentioned the perceptions sub-theme. Knowledge about these facilitators and barriers may inform the design and development of specific and relevant interventions to improve the 6-month exclusive breastfeeding rate in the Northeast region of Thailand and be useful in other contexts. Social media emerged as a newly perceived facilitator in the Thai context and may be a useful inclusion in a 6-month exclusive breastfeeding intervention model.

    We report the case in order to examine the effect of a mobile application program ("Diabetes & Nutrition") developed in 2011-2012 for self-management in patients with type 2 diabetes and to recommend important considerations when the mobile application program is developed. A 46-year-old man was newly diagnosed with type 2 diabetes in 2013 and had no complications. The height of the patient was 168 cm and the body weight was 75.6 kg. Nutrition education was conducted according to a medical prescription, and follow-up nutrition education was conducted after 3 and 6 months. After nutrition education, the patient was engaged in self-management using "Diabetes & Nutrition" program during 3 months. At 3 months, the body weight had decreased by 4.4 kg (from 75.6 to 71.2 kg), waist circumference by 5 cm (from 88 to 83 cm) and HbA1c level from 7.9% to 6.1%. Also at 3 months, the medication was reduced from from the dose of 850 mg to the dose of 500 mg metformin per twice a day. Since then, the patient did not continue to use the "Diabetes & Nutrition" because the level of blood glucose had stabilized, and the patient felt inconvenient and annoying to use the program. At 6 months, no significant change in the body weight and body composition was observed in comparison with those at 3 months. The present case demonstrates that the early use of "Diabetes & Nutrition" could be helpful for self-management of glycemic control in patients with type 2 diabetes. Developing self-management mobile application programs in the future will require strategies of how to promote continuous use of application program and self-management of type 2 diabetes.

    Ca45 incorporation into the bones of the limbs, particularly in the area of the muscle attachment increased in dogs as a result of 6 month hypokinesia. There were no phenomena of osteoporosis in the cortical layer of the diaphyses; however, changes in the form of osteons, an increase in the number of anastomoses between the channels and the thinning of the subperiosteal layer pointed to disturbances of the bone tissue reconstruction. Mineral saturation of the bone microstructures of the experimental dogs had a tendency to rise. No changes in the mechanical properties of the long bones occurred as a result of hypokinesia in dogs.

    Full Text Available E David Crawford, Jason M PhillipsUniversity of Colorado Health Sciences Center, Aurora, CO, USAAbstract: Two different 6-month GnRH agonist depot formulations approved for palliative treatment of advanced and metastatic prostate cancer in the United States – leuprolide acetate 45 mg and triptorelinpalmoate 22.5 mg – provide patients with efficacy and safety comparable to those of existing 1-, 3-, and 4-month GnRH agonist depots. However, the 6-month formulations can increase patient convenience, comfort, and compliance by reducing the number of physician visits and injections required. At the conclusion of their pivotal trials, the 6-month formulations demonstrated efficacy rates in achieving chemical castration (serum testosterone #50 ng/dL that ranged between 93% and 99%. As with existing GnRH agonist depot formulations, hot flashes represented the most common adverse event reported in trials of 6-month leuprolide acetate or triptorelin. As such, these products may prove useful not only for their labeled indication, but also as adjuncts to other treatments such as radical prostatectomy, radiotherapy, and chemotherapy. We recommend further research, including head-to-head trials between the 6-month GnRH depots, to refine our understanding of these products.Keywords: prostate cancer, leuprorelin, leuprolide, triptorelin, 6-month depot, testosterone

Newly admitted and long-term residents recruited consecutively from lists of residents aged 65 and older admitted for LTC, with stratification into groups with and without severe cognitive impairment. The study sample comprised 274 residents with complete data at baseline on delirium, dementia, and depression. Outcomes were 6-month mortality, functional decline (10-point decline from baseline on 100-point Barthel scale), and cognitive decline (3-point decline on 30-point Mini-Mental State Examination). Predictors included delirium (full syndrome or subsyndromal symptoms, using the Confusion Assessment Method), depression (Cornell Scale for Depression in Dementia), and dementia (chart diagnosis). The baseline prevalences of delirium, subsyndromal symptoms of delirium (SSD), depression, and dementia were 11%, 44%, 19%, and 66%, respectively. By 6 months, 10% of 274 had died, 19% of 233 had experienced functional decline, and 17% of 246 had experienced cognitive decline. An analysis using multivariable generalized linear models found the following significant interaction effects (P delirium and depression for functional decline, and between SSD and dementia for cognitive decline. Co-occurrence of delirium, SSD, depression, and dementia in LTC residents appears to affect some 6-month outcomes. Because of limited statistical power, it was not possible to draw conclusions about the effects of the co-occurrence of some syndromes on poorer outcomes. © 2014, Copyright the Authors Journal compilation © 2014, The American Geriatrics Society.

    Infants with Prader-Willi syndrome (PWS) show abnormalities of body composition. Children with PWS treated with growth hormone (GH) demonstrate improved body composition and motor skills. To assess body composition and motor changes in infants with PWS following 6 months GH therapy. Twenty-five infants with PWS (mean age 15.5 mo) underwent dual energy X-ray absorptiometry (DEXA) assessment of body composition, and motor assessment with the Toddler Infant Motor Evaluation (TIME). Patients were then randomized to treatment (Genotropin, 1 mg/m2/day) or control, with reassessment at 6 months. GH treatment significantly increased lean body mass (6.4 +/- 2.4 kg to 8.9 +/- 2.7 kg) and decreased body fat (27.6 +/- 9.9% to 22.4 +/- 10.3%). Age equivalent motor scores improved 4 months in the treated group vs 2 months in controls (p development improvement following 6 months GH therapy. We are investigating whether this improvement leads to long-term reductions in obesity.

  7. Soldiers at risk for individual readiness or morale problems during a six-month peacekeeping deployment to the Sinai.

    2000-10-01

    Longitudinal data were examined to predict soldiers' morale, satisfaction with Army life, and the effects of family issues on performance of duties during an overseas deployment (Sinai peacekeeping force during the spring of 1995). Few variables were significant predictors of the outcome measures; however, rank, leaders' support for families, prior satisfaction with Army life and with information released about the deployment appeared to predict better outcomes during the deployment. Rank and leaders' support for families appeared to be more important for married soldiers while satisfaction with predeployment information seemed to be more important for single soldiers. Those who were worried about the effects of the deployment on their families also tended to report interference with their duty performance because of family concerns, but that effect was offset by perceived leaders' concern for families. In conclusion, it appears to the authors that the pre-existing factors studied had much less to do with deployment outcomes than did leadership success before and during the deployment. That's good news for Army leaders about their power to have a positive effect on soldiers' morale during overseas deployments but may be bad news for anyone hoping to find a "magic bullet" for pre-identification of soldiers most likely to retain high morale, regardless of their leadership's competence during an overseas deployment.

    2016-11-28

    Color match and water sorption are two factors that affect restorative materials. Discoloration is essential in the lifespan of restorations. The aim of this study was to evaluate color change and water sorption of nine flowable composites at multiple time points over 6 months. 60 samples of each composite were divided into two groups (Color Change and Water Sorption/Solubility). Each Color Change group was divided into six subgroups, which were immersed in distilled water (DW), coffee (CF), Coca-Cola (CC), red wine (RW), tea (TE) and orange juice (OJ). The color was measured at the baseline, 1, 2, 3 and 4 weeks, and 3 and 6 months and color change values (ΔE) were calculated. Each Water Sorption [WS]/Solubility [WL] group was tested according to ISO 4049:2009. The data were evaluated using two-way ANOVA, Fisher's post-hoc test and Pearson's correlation test. The composite with the lowest ΔE differed for each solution: Filtek™ Bulk Fill in DW (∆E = 0.73 (0.17-1.759)); Vertise Flow in CF (∆E = 14.75 (7.91-27.41)), in TE (∆E = 7.27 (2.81-24.81)) and OJ (∆E = 3.17 (0.87-9.92)); Tetric EvoFlow® in CC (∆E = 1.27 (0.45-4.02)); and Filtek™ Supreme XTE in RW (∆E = 8.88 (5.23-19.59)). RW caused the most discoloration (∆E = 23.62 (4.93-51.36)). Vertise Flow showed the highest water sorption (WS = 69.10 ± 7.19). The Pearson test showed statistically significant positive correlations between water sorption and solubility and between water sorption and ∆E; the positive solubility-∆E correlation was not statistically significant. The findings suggest that water sorption is one factor associated with the ability of composites to discolor; however, discoloration is a multifactorial problem.

    FTY720 is a novel immunomodulator that was developed to produce optimal graft protection with improved safety and tolerability. Phase II studies have demonstrated the efficacy of FTY720 up to the doses of 2.5 mg with full-dose cyclosporine (FDC). This multicenter, double-blind, Phase IIb, randomized study evaluated the safety and efficacy of 5 mg FTY720 (n=87; Group 1) vs. 2.5 mg FTY720 (n=90; Group 2) vs. mycophenolate mofetil (MMF; n=94; Group 3) in de novo renal transplant patients receiving FDC and prednisone. The primary efficacy endpoint was the occurrence of treated biopsy-proven acute rejection, graft loss, death, or premature study discontinuation (composite endpoint) within 6 months. The primary endpoint was superior in Group 1 (24%) and statistically noninferior in Group 2 compared to Group 3 (24.1% vs. 29.2% vs. 39.4%; P=0.025 and 0.0039, respectively). FTY720 plus FDC was generally well tolerated, with a similar incidence of adverse events across all groups. FTY720 was associated with higher incidence of bradycardia (Group 1: 26.4%, P=0.0002 and Group 2: 15.6%, P=0.046, vs. Group 3: 6.4%), respiratory disorders (Group 1: 40.2%, not significant [P=NS] and Group 2: 34.4%, P=NS vs. Group 3: 28.7%). One macular edema occurred in Group 2. Lower creatinine clearances were observed with FTY720 versus MMF (Group 1: 52.4 ml/min, P=NS and Group 2: 51.7 ml/min, P=0.039 vs. Group 3: 62.5 ml/min). Although FTY720 with FDC provided adequate protection from acute rejection the safety profile was less favorable for adverse events than current standard immunosuppression in de novo renal transplant patients.

    1985-01-01

    Following a recommendation by the International Union for Pure and Applied Chemistry (IUPAC), the groups of the periodic table shall be numbered from 1 to 18, instead of I to VIII as before. The recommendations has been approved of by the Committee on Nomenclature of the American Chemical Society. The new system abandons the distinction between main groups (a) and auxiliary groups (b), which in the past frequently has been the reason for misunderstandings between European and American chemists, due to different handling. The publishing house VCH Verlagsgesellschaft recently produced a new periodic table that shows the old and the new numbering system together at a glance, so that chemists will have time to get familiar with the new system. In addition the new periodic table represents an extensive data compilation arranged by elements. The front page lists the chemical properties of elements, the back page their physical properties.

  15. Thyrotoxic periodic paralysis

    Directory of Open Access Journals (Sweden)

    Rojith Karandode Balakrishnan

    2011-01-01

    Full Text Available This article aims at highlighting the importance of suspecting thyrotoxicosis in cases of recurrent periodic flaccid paralysis; especially in Asian men to facilitate early diagnosis of the former condition. A case report of a 28 year old male patient with recurrent periodic flaccid paralysis has been presented. Hypokalemia secondary to thyrotoxicosis was diagnosed as the cause of the paralysis. The patient was given oral potassium intervention over 24 hours. The patient showed complete recovery after the medical intervention and was discharged after 24 hours with no residual paralysis. Thyrotoxic periodic paralysis (TPP is a complication of thyrotoxicosis, more common amongst males in Asia. It presents as acute flaccid paralysis in a case of hyperthyroidism with associated hypokalemia. The features of thyrotoxicosis may be subtle or absent. Thus, in cases of recurrent or acute flaccid muscle paralysis, it is important to consider thyrotoxicosis as one of the possible causes, and take measures accordingly.

  16. Periodically poled silicon

    2010-02-01

    Bulk centrosymmetric silicon lacks second-order optical nonlinearity χ(2) - a foundational component of nonlinear optics. Here, we propose a new class of photonic device which enables χ(2) as well as quasi-phase matching based on periodic stress fields in silicon - periodically-poled silicon (PePSi). This concept adds the periodic poling capability to silicon photonics, and allows the excellent crystal quality and advanced manufacturing capabilities of silicon to be harnessed for devices based on χ(2)) effects. The concept can also be simply achieved by having periodic arrangement of stressed thin films along a silicon waveguide. As an example of the utility, we present simulations showing that mid-wave infrared radiation can be efficiently generated through difference frequency generation from near-infrared with a conversion efficiency of 50% based on χ(2) values measurements for strained silicon reported in the literature [Jacobson et al. Nature 441, 199 (2006)]. The use of PePSi for frequency conversion can also be extended to terahertz generation. With integrated piezoelectric material, dynamically control of χ(2)nonlinearity in PePSi waveguide may also be achieved. The successful realization of PePSi based devices depends on the strength of the stress induced χ(2) in silicon. Presently, there exists a significant discrepancy in the literature between the theoretical and experimentally measured values. We present a simple theoretical model that produces result consistent with prior theoretical works and use this model to identify possible reasons for this discrepancy.

    International Nuclear Information System (INIS)

    Muller, R.A.

    1988-01-01

    Two remarkable discoveries of the last decade have profound implications for astrophysics and for geophysics. These are the discovery by Alvarez et al., that certain mass extinctions are caused by the impact on the earth of a large asteroid or comet, and the discovery by Raup and Sepkoski that such extinctions are periodic, with a cycle time of 26 to 30 million years. The validity of both of these discoveries is assumed and the implications are examined. Most of the phenomena described depend not on periodicity, but just on the weaker assumption that the impacts on the earth take place primarily in showers. Proposed explanations for the periodicity include galactic oscillations, the Planet X model, and the possibility of Nemesis, a solar companion star. These hypotheses are critically examined. Results of the search for the solar companion are reported. The Deccan flood basalts of India have been proposed as the impact site for the Cretaceous impact, but this hypotheisis is in contradiction with the conclusion of Courtillot et al., that the magma flow began during a period of normal magnetic field. A possible resolution of this contradiction is proposed

    1986-01-01

    A case of thyrotoxic periodic paralysis is reported in a Hispanic man with an unusual recurrence six weeks after radioactive iodine treatment. Thyrotoxic periodic paralysis has now been well characterized in the literature: it occurs primarily in Orientals with an overwhelming male preponderance and a higher association of specific HLA antigens. Clinical manifestations include onset after high carbohydrate ingestion or heavy exertion, with progressive symmetric weakness leading to flaccid paralysis of the extremities and other muscle groups, lasting several hours. If hypokalemia is present, potassium administration may help abort the attack. Although propranolol can be efficacious in preventing further episodes, the only definitive treatment is establishing a euthyroid state. The pathophysiology is still controversial, but reflects altered potassium and calcium dynamics as well as certain morphologic characteristics within the muscle unit itself

    Impressive progress has been made in recent years on massive star formation, yet the involved high optical depths even at submm/mm wavelengths make it difficult to reveal its details. Recently, accretion bursts of massive YSOs have been identified to cause flares of Class II methanol masers (methanol masers for short) due to enhanced mid-IR pumping. This opens a new window to protostellar accretion variability, and implies that periodic methanol masers hint at cyclic accretion. Pinning down the cause of the periodicity requires joint IR and radio monitoring. We derived the first IR light curve of a periodic maser host from NEOWISE data. The source, G107.298+5.639, is an intermediate-mass YSO hosting methanol and water masers which flare every 34.5 days. Our recent joint K-band and radio observations yielded first but marginal evidence for a phase lag between the rise of IR and maser emission, respectively, and revealed that both NEOWISE and K-band light curves are strongly affected by the light echo from the ambient dust. Both the superior resolution of IRAC over NEOWISE and the longer wavelengths compared to our ground-based imaging are required to inhibit the distractive contamination by the light echo. Thus, we ask for IRAC monitoring of G107 to cover one flare cycle, in tandem with 100-m Effelsberg and 2-m Wendelstein radio and NIR observations to obtain the first high-quality synoptic measurements of this kind of sources. The IR-maser phase lag, the intrinsic shape of the IR light curves and their possible color variation during the cycle allow us to constrain models for the periodic maser excitation. Since methanol masers are signposts of intermediate-mass and massive YSOs, deciphering their variability offers a clue to the dynamics of the accretion-mediated growth of massive stars and their feedback onto the immediate natal environment. The Spitzer light curve of such a maser-hosting YSO would be a legacy science product of the mission.

    The importance of effective communication, a key component of teamwork, is well recognised in the healthcare setting. Establishing a culture that encourages and empowers team members to speak openly in the cardiothoracic (CT) operating room (OR) is necessary to improve patient safety in this high-risk environment. This study will take place at Barnes-Jewish Hospital, an academic hospital in affiliation with Washington University School of Medicine located in the USA. All team members participating in cardiac and thoracic OR cases during this 17-month study period will be identified by the primary surgical staff attending on the OR schedule.TeamSTEPPS (Team Strategies and Tools to Enhance Performance and Patient Safety) training course will be taught to all CT OR staff. Before TeamSTEPPS training, staff will respond to a 39-item questionnaire that includes constructs from the Agency for Healthcare Research and Quality Hospital Survey on Patient Safety Culture, Edmondson's 'Measure of psychological safety' questionnaire, and questionnaires on turnover intentions, job satisfaction and 'burnout'. The questionnaires will be readministered at 6 and 12 months.The primary outcomes to be assessed include the perceived psychological safety of CT OR team members, the overall effect of TeamSTEPPS on burnout and job satisfaction, and observed turnover rate among the OR nurses. As secondary outcomes, we will be assessing self-reported rates of medical error and near misses in the ORs with a questionnaire at the end of each case. Ethics approval is not indicated as this project does not meet the federal definitions of research requiring the oversight of the Institutional Review Board (IRB). Patient health information (PHI) will not be generated during the implementation of this project. Results of the trial will be made accessible to the public when published in a peer-reviewed journal following the completion of the study. © Article author(s) (or their employer(s) unless

    Regulations require that electric power generation facilities monitor their liquid effluents. Acute lethality tests are simple, rapid standard methods for measuring potential impacts on aquatic ecosystems. These toxicity tests will detect harmful concentrations of chemicals and mixtures of compounds in effluents, but compliance with end of pipe limits for acute toxicity will not necessarily control all adverse environmental effects. In these tests, aquatic organisms were exposed to undiluted effluent, as well as a series of effluent dilutions for a fixed period of time. This report is a compilation of six months of test results. Typically the most toxic samples were taken from the waste treatment plant (WTP) neutral sumps. This was true for fossil fueled as well as for nuclear generating stations. tabs., figs

    Trees grown from seed gamma-irradiated at exposures of 150, 300, 600, 1200, 1800, 2400, 3600, 4800, 7200, 9600, 14,400 and 19,200 R, and a control were evaluated for survival, growth, flowering, and cone and seed production over a 10-yr period following seed irradiation. The LD 50 for seed germination was approximately 16,000 R, but that for tree survival was 12,600 R at six months, and 11,300 R after 10-yr. Shoot growth in surviving trees was significantly reduced at seed exposures as low as 7200 R during the first 2 yr and differences in tree height among exposure levels were still significant after 10 yr. Earliness of flowering and number of cones per tree were not significantly related to seed exposure. However, total seeds per cone and percent of filled seed differed significantly among exposures through at least the first 6 yr, indicating persistent radiation induced genetic changes. (author)

    Phenomena of electromagnetically induced transparency (PEIT) may be interpreted by the Autler-Townes Splitting (ATS), where the coupled states are split by the coupling laser field, or by the quantum destructive interference (QDI), where the atomic phases caused by the coupling laser and the probe laser field cancel. We propose modulated experiments to explore the PEIT in an alternative way by periodically modulating the coupling and the probe fields in a Λ-type three-level system initially in a dark state. Our analytical and numerical results rule out the ATS interpretation and show that the QDI interpretation is more appropriate for the modulated experiments. Interestingly, dark state persists in the double-modulation situation where control and probe fields never occur simultaneously, which is significant difference from the traditional dark state condition. The proposed experiments are readily implemented in atomic gases, artificial atoms in superconducting quantum devices, or three-level meta-atoms in meta-materials.

  9. [Childhood periodic syndromes].

    2010-01-01

    This review focuses on the so-called "periodic syndromes of childhood that are precursors to migraine", as included in the Second Edition of the International Classification of Headache Disorders. Three periodic syndromes of childhood are included in the Second Edition of the International Classification of Headache Disorders: abdominal migraine, cyclic vomiting syndrome and benign paroxysmal vertigo, and a fourth, benign paroxysmal torticollis is presented in the Appendix. The key clinical features of this group of disorders are the episodic pattern and intervals of complete health. Episodes of benign paroxysmal torticollis begin between 2 and 8 months of age. Attacks are characterized by an abnormal inclination and/or rotation of the head to one side, due to cervical dystonia. They usually resolve by 5 years. Benign paroxysmal vertigo presents as sudden attacks of vertigo, accompanied by inability to stand without support, and lasting seconds to minutes. Age at onset is between 2 and 4 years, and the symptoms disappear by the age of 5. Cyclic vomiting syndrome is characterized in young infants and children by repeated stereotyped episodes of pernicious vomiting, at times to the point of dehydration, and impacting quality of life. Mean age of onset is 5 years. Abdominal migraine remains a controversial issue and presents in childhood with repeated stereotyped episodes of unexplained abdominal pain, nausea and vomiting occurring in the absence of headache. Mean age of onset is 7 years. Both cyclic vomiting syndrome and abdominal migraine are noted for the absence of pathognomonic clinical features but also for the large number of other conditions to be considered in their differential diagnoses. Diagnostic criteria, such as those of the Second Edition of the International Classification of Headache Disorders and the North American Society for Pediatric Gastroenterology, Hepatology and Nutrition, have made diagnostic approach and management easier.

    Full Text Available Folic acid is an essential vitamin which has been known in recent 50 years. It plays an important role in period of neurogenesis. The substitution of folic acid is one of the important parts in the complex treatment of anaemia in premature newborns. It is also a component of artificial milk formulae or breast milk following mother’s intake. Fortification of foods with folic acid for population in the world is still discussed. To determine optimal dose of folic acid in premature newborns is difficult. Daily recommended doses of folic acid in infants under the six months were identified. The needs of folic acid in newborns vary. It depends upon the gestational age, body reserves at birth or maternal status of folates during gravidity. On the other hand there is a risk of accumulation of unmetabolised folic acid in circulation of newborns after mandatory folic acid fortification in some countries, which were reported in some studies. The safe upper limits of folic acid intake in premature newborns are not known. In this review article authors inform about the clear positive effect of folic acid in prenatal and neonatal period, but excessive doses of folic acid could present risk of accumulation and possible adverse effects. To follow up these notions further studies are required.

    Milk progesterone profiles in Chengdu Mah (CM), Saanen (S) and crossbred (CM x S, F1) goats were determined using radioimmunoassay throughout the period from kidding to the beginning of the next breeding season. Different patterns of progesterone profiles were recorded in these does. When milk progesterone concentrations were elevated above 6 ng/mL for at least 6 days they were regarded as signs of ovarian activity. The frequencies of such rises during anoestrus were 4.0, 1.8 and 2.5 per animal in CM, S and F1 goats respectively. The frequencies of progesterone rise were higher than that of behavioural oestrus in the does. After exposing the does to the buck three times during the anoestrus period, no significant 'male effect' was observed on the milk progesterone level or behavioural oestrus during the first six months after kidding. The male effect on behavioural oestrus became apparent only in the seventh month after kidding, while milk progesterone levels did not change markedly compared with those of the control does.

    Full Text Available ABSTRACT OBJECTIVE: The aim of this systematic review was to evaluate the duration of the retention period in growing patients undergoing maxillary expansion and its relation with posterior crossbite stability. METHODS: Search strategies were executed for electronic databases Cochrane Library, Web of Science, PubMed and Scopus, which were completed on January 15, 2016. The inclusion criteria included randomized, prospective or retrospective controlled trials in growing subjects with posterior crossbite; treated with maxillary expanders; retention phase after expansion; post-retention phase of at least 6 months. The exclusion criteria were anterior crossbite, craniofacial anomalies, surgery or another orthodontic intervention; case reports; author’s opinions articles, thesis, literature reviews and systematic reviews. The risk of bias of selected articles was assessed with Cochrane risk of bias tool for RCTs and Downs and Black checklist for non-RCTs. RESULTS: A total of 156 titles/abstracts was retrieved, 44 full-texts were examined, and 6 articles were selected and assessed for their methodological quality. The retention period after maxillary expansion ranged between 4 weeks and 16 months. Fixed (acrylic plate, Haas, Hyrax and quad-helix or removable (Hawley and Hawley expander appliances were used for retention. CONCLUSIONS: Six months of retention with either fixed or removable appliances seem to be enough to avoid relapse or to guarantee minimal changes in a short-term follow-up.

  18. Nonparametric Inference for Periodic Sequences

    KAUST Repository

    Sun, Ying

    2012-02-01

    This article proposes a nonparametric method for estimating the period and values of a periodic sequence when the data are evenly spaced in time. The period is estimated by a "leave-out-one-cycle" version of cross-validation (CV) and complements the periodogram, a widely used tool for period estimation. The CV method is computationally simple and implicitly penalizes multiples of the smallest period, leading to a "virtually" consistent estimator of integer periods. This estimator is investigated both theoretically and by simulation.We also propose a nonparametric test of the null hypothesis that the data have constantmean against the alternative that the sequence of means is periodic. Finally, our methodology is demonstrated on three well-known time series: the sunspots and lynx trapping data, and the El Niño series of sea surface temperatures. © 2012 American Statistical Association and the American Society for Quality.

    In this Letter, for a general class of delayed periodic Lotka-Volterra systems, we prove some new results on the existence of positive periodic solutions by Schauder's fixed point theorem. The global asymptotical stability of positive periodic solutions is discussed further, and conditions for exponential convergence are given. The conditions we obtained are weaker than the previously known ones and can be easily reduced to several special cases

    International Nuclear Information System (INIS)

    Khlebnikov, S.Yu.; Rubakov, V.A.; Tinyakov, P.G.

    1991-04-01

    We discuss the role of periodic euclidean solutions with two turning points and zero winding number (periodic instantons) in instanton induced processes below the sphaleron energy E sph . We find that the periodic instantons describe certain multiparticle scattering events leading to the transitions between topologically distinct vacua. Both the semiclassical amplitudes and inital and final states of these transitions are determined by the periodic instantons. Furthermore, the corresponding probabilities are maximal among all states of given energy. We show that at E ≤ E sph , the periodic instantons can be approximated by infinite chains of ordinary instantons and anti-instantons, and they naturally emerge as deformations of the zero energy instanton. In the framework of 2d abelian Higgs model and 4d electroweak theory we show, however, that there is not obvious relation between periodic instantons and two-particle scattering amplitudes. (orig.)

    The associations between relationship adjustment and symptoms of depression and anxiety were evaluated in a sample of pregnant married or cohabiting women (N = 113) who were at risk for perinatal depression because of a prior history of major depression. Women completed self-report measures of relationship adjustment, depressive symptoms, and anxiety symptoms monthly during pregnancy and for the first six months following the birth of their child. Multilevel modeling was used to examine concurrent and time-lagged within-subjects effects for relationship adjustment and depressive and anxiety symptoms. Results revealed that (a) relationship adjustment was associated with both depressive symptoms and anxiety symptoms in concurrent analyses; (b) relationship adjustment was predictive of subsequent anxiety symptoms but not subsequent depressive symptoms in lagged analyses; and (c) depressive symptoms were predictive of subsequent relationship adjustment in lagged analyses with symptoms of depression and anxiety examined simultaneously. These results support the continued investigation into the cross-sectional and longitudinal associations between relationship functioning and depressive and anxiety symptoms in women during pregnancy and the postpartum period. 2011 APA, all rights reserved

    Period mappings were introduced in the sixties [4] to study variation of complex structures of families of algebraic varieties. The theory of tautological systems was introduced recently [7,8] to understand period integrals of algebraic manifolds. In this paper, we give an explicit construction of a tautological system for each component of a period mapping. We also show that the D-module associated with the tautological system gives rise to many interesting vanishing conditions for period integrals at certain special points of the parameter space.

    1980-01-01

    A microprocessor controlled digital period meter has been developed and tested operationally on a reactor at Argonne National Laboratory. The principle of operation is the mathematical relationship between asymptotic periods and pulse counting circuitry. This relationship is used to calculate and display the reactor periods over a range of /plus or minus/1 second to /plus or minus/999 seconds. The time interval required to update each measurement automatically varies from 8 seconds at the lowest counting rates to 2 seconds at higher counting rates. The paper will describe hardware and software design details and show the advantages of this type of Period Meter over the conventional circuits. 1 ref

    Four different Aspergilli (Aspergillus oryzae, A. parasiticus, A. terreus and A. versicolor) were grown on wheat grains underdifferent degrees of relative humidity 14, 50, 74, 80 and 90%. Samples of wheat grains were taken monthly for a period of six months and examined for mycotoxin production. A. oryzae was found to produce aflatoxins B1, B2, zearalenone, DON and T-2 toxins under elevated degrees of humidity and prolonged periods of storage. A. parasiticus produced aflatoxins B1, G1, NIV, DON and T-2 toxins in high concentrations during a period of not more than three months storage at 14% relative humidity; at an increased level of relative humidity of 74% ochratoxin A, zearalenone and sterigmatocystin were also produced at high levels. The isolate was drastic in toxin production. A. terrus produced toxins at 14% relative humidity (aflatoxin G2 and DON) at levels much higher than any other prevalent degrees of humidity. A. versicolor is highly sensitive to relative humidity and grain moisture content It produced aflatoxins B1, G1, NIV and DON at a relative humidity of 50% and another toxins (aflatoxin G2, ochratoxins A, B and zearalenone) at 74%. The microorganism can be considered a trichothecene producer under suitable relative humidity.

  7. Forward Period Analysis Method of the Periodic Hamiltonian System.

    Pengfei Wang

    Full Text Available Using the forward period analysis (FPA, we obtain the period of a Morse oscillator and mathematical pendulum system, with the accuracy of 100 significant digits. From these results, the long-term [0, 1060] (time unit solutions, ranging from the Planck time to the age of the universe, are computed reliably and quickly with a parallel multiple-precision Taylor series (PMT scheme. The application of FPA to periodic systems can greatly reduce the computation time of long-term reliable simulations. This scheme provides an efficient way to generate reference solutions, against which long-term simulations using other schemes can be tested.

  8. Detecting periodicities with Gaussian processes

    Directory of Open Access Journals (Sweden)

    Nicolas Durrande

    2016-04-01

    Full Text Available We consider the problem of detecting and quantifying the periodic component of a function given noise-corrupted observations of a limited number of input/output tuples. Our approach is based on Gaussian process regression, which provides a flexible non-parametric framework for modelling periodic data. We introduce a novel decomposition of the covariance function as the sum of periodic and aperiodic kernels. This decomposition allows for the creation of sub-models which capture the periodic nature of the signal and its complement. To quantify the periodicity of the signal, we derive a periodicity ratio which reflects the uncertainty in the fitted sub-models. Although the method can be applied to many kernels, we give a special emphasis to the Matérn family, from the expression of the reproducing kernel Hilbert space inner product to the implementation of the associated periodic kernels in a Gaussian process toolkit. The proposed method is illustrated by considering the detection of periodically expressed genes in the arabidopsis genome.

    1990-01-01

    The sense of long axis orientation of Comet Halley during the Vega 1 encounter must be reversed from that deduced by Sagdeev et al. (1986) in order to harmonize the comet nucleus' Vega/Giotto-observed orientations with periodicities extracted from time-series brightness data. It is also demonstrated that Vega/Giotto observations can be satisfied by either a 2.2- or 3.7-day long-axis free precession period. A novel Fourier algorithm is used to reanalyze five independent data sets; strong evidence is adduced for periods harmonically related to a 7.4-day period. The preferred candidate models for Halley's nuclear rotation are characterized by a long-axis precession period of 3.7 days.

    1990-01-01

    The class of recurrent novae (RN) with thermonuclear runaways contains only three systems (T Pyx, U Sco, and V394 CrA), for which no orbital periods are known. This paper presents a series of photometric observations where the orbital periods for all three systems are discovered. T Pyx is found to have sinusoidal modulation with an amplitude of 0.08 mag and a period of 2.3783 h (with a possible alias of 2.6403 h). U Sco is found to be an eclipsing system with an eclipse amplitude of roughly 1.5 mag and an orbital period of 1.2344 days. V394 CrA is found to have sinusoidal modulation with an amplitude of 0.5 mag and a period of 0.7577 days. Thus two out of three RN with thermonuclear runaways (or five out of six for all RN) have evolved companions. 16 refs

    A three-variable model of the Belousov-Zhabotinsky reaction system subject to external sinusoidal perturbations is investigated by means of frequency spectrum analysis. In the period-1 window of the model, the transitions from periodicity to chaos are observed; in the chaotic window, the transitions from chaos to periodicity are found. The former might be understood by the circle map of two coupled oscillators, and the latter is partly explained by the resonance between the main frequency of the chaos and the frequency of the external periodic perturbations

    Full Text Available The Croatian (Yugoslav Academy of Sciences and Arts was the first academy to elect D. I. Mendeleev as its honorary member (1882, whereas the periodic table of the elements has been taught regularly at the Zagreb University since 1888. The early interest of Croatian chemists in the periodic table should be attributed primarily to their pan-Slavic attitude, particularly as proof that Slavic people were able to produce "their own Newtons" (M. V. Lomonosov and D. I. Mendeleev. Such enthusiastic views, however, did not help in analyzing the contribution of Mendeleev and other scientists to the discovery and development of the periodic table of the elements.

    The more self-crossing points an orbit has the more complex it is. We introduce the topological imprint to characterize crossing points and focus on the period-doubling cascade. The period-doubling cascade topological imprint determines the topological imprint for orbits in chaotic bands. In addition, there is a closer link between this concept and the braids studied by Lettelier et al (2000 J. Phys. A: Math. Gen. 33 1809–25). (paper)

  16. Minimum period and the gap in periods of Cataclysmic binaries

    International Nuclear Information System (INIS)

    Paczynski, B.; Sienkiewicz, R.

    1983-01-01

    The 81 minute cutoff to the orbital periods of hydrogen-rich cataclysmic binaries is consistent with evolution of those systems being dominated by angular momentum losses due to gravitational radiation. Unfortunately, many uncertainties, mainly poorly known atmospheric opacities below 2000 K, make is physically impossible to verify the quadrupole formula for gravitational radiation by using the observed cutoff at 81 minutes. The upper boundary of the gap in orbital periods observed at about 3 hours is almost certainly due to enhanced angular momentum losses from cataclysmic binaries which have longer periods. The physical mechanism of those losses is not identified, but a possible importance of stellar winds is pointed out. The lower boundary of the gap may be explained with the oldest cataclysmic binaries, whose periods evolved past the minimum at 81 minutes and reached the value of 2 hours within about 12 x 10 9 years after the binary had formed. Those binaries should have secondary components of only 0.02 solar masses, and their periods could be used to estimate ages of the oldest cataclysmic stars, and presumably the age of Galaxy. An alternative explanation for the gap requires that binaries should be detached while crossing the gap. A possible mechanism for this phenomenon is discussed. It requires the secondary components to be about 0.2 solar masses in the binaries just below the gap

  17. Commuting periodic operators and the periodic Wigner function

    International Nuclear Information System (INIS)

    Zak, J

    2004-01-01

    Commuting periodic operators (CPO) depending on the coordinate x-hat and the momentum p-hat operators are defined. The CPO are functions of the two basic commuting operators exp(i x-hat 2π/a) and exp(i/h p-hat a), with a being an arbitrary constant. A periodic Wigner function (PWF) w(x, p) is defined and it is shown that it is applicable in a normal expectation value calculation to the CPO, as done in the original Wigner paper. Moreover, this PWF is non-negative everywhere, and it can therefore be interpreted as an actual probability distribution. The PWF w(x, p) is shown to be given as an expectation value of the periodic Dirac delta function in the phase plane. (letter to the editor)

    Full Text Available The information expressed in humanities datasets is inextricably tied to a wider discursive environment that is irreducible to complete formal representation. Humanities scholars must wrestle with this fact when they attempt to publish or consume structured data. The practice of “nanopublication,” which originated in the e-science domain, offers a way to maintain the connection between formal representations of humanities data and its discursive basis. In this paper we describe nanopublication, its potential applicability to the humanities, and our experience curating humanities nanopublications in the PeriodO period gazetteer.

    Periodic testing forms a remarkable part of the regular work tasks of the shift crew. Testing is generally carried out beside the daily monitoring and control work. Even remarkable plant related differences may occur in the procedures and routines used in periodic testing. The goal is still always the same, to regularly ensure that the systems and equipment are in working order according to their design. This presentation studies with examples the execution and scope of periodic testing as well as the routines and procedures used in the testing in Loviisa power plant. The presentation is based on the testing procedures of Loviisa power plant and the aim is not to compare them to the procedures of other plants. The scope of periodic testing has increased and the routines and procedures have been developed as the operation experience has increased. The assessment of the need of periodic testing and the consideration of the practical execution possibilities should be a part of the plant's planning phase as a part of the planning process.

    2006-04-24

    Our aim was to examine suicidal behaviours among asylum seekers in Denmark. A retrospective quantitative analysis of data from reports to the Danish Red Cross Asylum Department on suicidal behaviours among persons over 15 years of age in the period 2001-2003 and from 54 medical records of suicidal asylum seekers in Denmark in 2001 was carried out. The number of suicide attempts by asylum seekers in 2001 was 3.4 times higher than by Danish residents. Furthermore, the rate of suicide attempts by asylum seekers grew in the following two years. Suicidal behaviours are most frequent among asylum seekers between 30 and 39 years of age. There are national differences. The preferred method of suicide attempt is intake of medicine. Stress-related diagnoses constitute three fourths of all diagnoses. One analysis suggests that the long waiting time (average 20.8 months) faced by asylum seekers combined with rejection of asylum cases may trigger a rapid suicidal reaction. Other factors may also be active, as 44% of suicide attempts occur within six months after arrival in the country. The results are discussed in relation to other research on the vulnerability of refugees, immigrants and asylum seekers and also in relation to length of waiting time, growing mental morbidity and the increasing number of rejections of asylum applications during recent years, a period characterized by a reduction of staff at the asylum centers. It is recommended that prevention of suicidal behaviour shall be given higher legal and administrative priority.

    We discuss a realization of a small field inflation based on string inspired supergravities. In theories accompanying extra dimensions, compactification of them with small radii is required for realistic situations. Since the extra dimension can have a periodicity, there will appear (quasi-)periodic functions under transformations of moduli of the extra dimensions in low energy scales. Such a periodic property can lead to a UV completion of so-called multi-natural inflation model where inflaton potential consists of a sum of multiple sinusoidal functions with a decay constant smaller than the Planck scale. As an illustration, we construct a SUSY breaking model, and then show that such an inflaton potential can be generated by a sum of world sheet instantons in intersecting brane models on extra dimensions containing orbifold.

    Full Text Available The topic according to this title is admittedly a broad one, embracing two very general concepts of time and of the cultural valuation of artistic products. Both phenomena are, in the present view, largely constructed by their contemporary cultures, and given authority to a great extent from the prestige of the past. The antiquity of tradition brings with it a certain cachet. Even though there may be peripheral debates in any given society which question the specifics of periodization or canonicity, individuals generally accept the consensus designation of a sequence of historical periods and they accept a list of highly valued artistic works as canonical or authoritative. We will first examine some of the processes of periodization and of canon-formation, after which we will discuss some specific examples of how these processes have worked in the sport of two ancient cultures, namely Greece and Mesoamerica.

  3. Periodicity and repeatability in data

    Science.gov (United States)

    Southwood, D.

    Using magnetic data from the first two years in Saturn orbit, the basic periodicity of apparent is examined with the aim of elucidating the `cam' shaft model of Espinosa et al. (2003) identifying the nature of the `cam' and giving a definitive period for its rotation. An initial hypothesis, supported by the spectral analysis of analysis of the first 8 months in orbit Gianpieri et al. (2006), is made that the source of the period is linked to something inside the planet and therefore that the source inertia means that the period effectively does not change over the 2 years. Moreover one expects that the source phase is fixed. Using this approach, not only can the period identified by spectral analysis (647.1 + 0.6 min.) be verified but also by phase analysis between successive passes over the 2 years the period can be refined to 647.6 + 0.1 min. The signal itself is remarkably reproducible from pass to pass. It appears in all three components of the field and its polarisation is unambiguously not attributable to direct detection of an internal field. Not only does the signal not decay rapidly with distance from the planet, but although it has the m=1 symmetry of a tilted dipole, the field lines diverge from the planet indicating an exterior source. This feature led to the `cam' model. The polarisation and comparisons of passes with different latitude profiles show a surprising north-south symmetry in the azimuthal field. The absence of asymmetry with respect to the magnetic equator rules out a direct magnetospheric-ionospheric interaction source. Accordingly, it is proposed that the basic `cam' effect is generated by a single hemisphere anomaly which creates hemisphere to hemisphere field aligned currents. The existence of Saturn phase related anomaly appears to produce a basic asymmetry in the inner magnetosphere that sets the phase of both an inflowing and outflowing sector in a rotating circulation system.

  4. An improved test for periodicity

    Davies, S.R.

    I discuss two widely used methods of testing for periodicity, phase dispersion minimization and epoch-folding. Using an analysis of variance approach, I demonstrate the close relationship between these two methods. I also show that the significance test sometimes used in phase dispersion minimization is statistically inaccurate, and that the test used in epoch-folding is an approximation valid only for large sample sizes. I propose a new test statistic, applicable to either epoch-folding or PDM, which is statistically sound for all sample sizes, and which is also more sensitive to periodicity than the test statistics previously used with these two methods.

    Full Text Available Background. Sigmoid volvulus is a rare complication of pregnancy and the puerperium. Case. A 19-year-old patient, gravida 1 para 0 at 41 0/7 weeks of gestation, admitted for late-term induction of labor underwent an uncomplicated primary low transverse cesarean delivery for arrest of descent. Her postoperative period was complicated by sudden onset of abdominal pain and the ultimate diagnosis of sigmoid volvulus. Conclusion. Prompt surgical evaluation of an acute abdomen in the postpartum period is essential; delayed diagnosis and treatment can lead to significant maternal morbidity and mortality.

    The periodic adsorption processes have been widely used for industrial applications, mainly because it spends less energy than the usual gas separation processes, like the cryogenic distillation. The largest commercial application of periodic adsorption processes is the pressure swing adsorption (PSA) applied to hydrogen purification. Although its wide use in the chemical and petrochemical industry, there are no reports in the open literature about complete modeling studies of a complex commercial unit, with multiple adsorbents and multiple beds and several feed components. This study has as objective the modeling, optimization and dynamical analysis of an industrial PSA unit for hydrogen purification. (author)

    1979-01-01

    There is at the present time a need in accurate models to asess the availability of periodically tested stand-by systems. This paper shows how to improve the well known 'saw-tooth curve' model in order to take into account various reliability parameters. A model is developed to assess the pointwise and the mean availabilities of periodically tested stand-by systems. Exact and approxination formulae are given. In addition, the model developed herein leads to optimize the test interval in order to minimize the mean unavailability. A safety diesel in a nuclear power plant is given as an example

  8. Periodic and quasiperiodic revivals in periodically driven interacting quantum systems

    2018-01-01

    Recently it has been shown that interparticle interactions generically destroy dynamical localization in periodically driven systems, resulting in diffusive transport and heating. In this Rapid Communication we rigorously construct a family of interacting driven systems which are dynamically localized and effectively decoupled from the external driving potential. We show that these systems exhibit tunable periodic or quasiperiodic revivals of the many-body wave function and thus of all physical observables. By numerically examining spinless fermions on a one-dimensional lattice we show that the analytically obtained revivals of such systems remain stable for finite systems with open boundary conditions while having a finite lifetime in the presence of static spatial disorder. We find this lifetime to be inversely proportional to the disorder strength.

    One purpose of this review was to raise awareness for the new autoinflammatory syndromes. These diseases are increasingly recognized and are in the differential diagnosis of many disease states. We also aimed to review the latest recommendations for the diagnosis, management, and treatment of these patients. Familial Mediterranean fever (FMF), cryopyrin-associated periodic syndrome (CAPS), tumor necrosis factor receptor-associated periodic fever syndrome (TRAPS), and hyperimmunoglobulinemia D and periodic fever syndrome/mevalonate kinase deficiency (HIDS/MVKD) are the more common autoinflammatory diseases that are characterized by periodic fevers and attacks of inflammation. Recently much collaborative work has been done to understand the characteristics of these patients and to develop recommendations to guide the physicians in the care of these patients. These recent recommendations will be summarized for all four diseases. FMF is the most common periodic fever disease. We need to further understand the pathogenesis and the role of single mutations in the disease. Recently, the management and treatment of the disease have been nicely reviewed. CAPS is another interesting disease associated with severe complications. Anti-interleukin-1 (anti-IL-1) treatment provides cure for these patients. TRAPS is characterized by the longest delay in diagnosis; thus, both pediatricians and internists should be aware of the characteristic features and the follow-up of these patients. HIDS/MVKD is another autoinflammatory diseases characterized with fever attacks. The spectrum of disease manifestation is rather large in this disease, and we need further research on biomarkers for the optimal management of these patients.

    The incubation period for typhoid, polio, measles, leukemia and many other diseases follows a right-skewed, approximately lognormal distribution. Although this pattern was discovered more than sixty years ago, it remains an open question to explain its ubiquity. Here, we propose an explanation based on evolutionary dynamics on graphs. For simple models of a mutant or pathogen invading a network-structured population of healthy cells, we show that skewed distributions of incubation periods emerge for a wide range of assumptions about invader fitness, competition dynamics, and network structure. The skewness stems from stochastic mechanisms associated with two classic problems in probability theory: the coupon collector and the random walk. Unlike previous explanations that rely crucially on heterogeneity, our results hold even for homogeneous populations. Thus, we predict that two equally healthy individuals subjected to equal doses of equally pathogenic agents may, by chance alone, show remarkably different time courses of disease.

  18. Period of an Interrupted Pendulum

    2002-11-01

    While demonstrating a classic conservation-of-energy problem to my AP Physics students, I became curious about the periodic motion that ensued for certain initial conditions. The original problem consists of releasing a mass at the end of a string from an initial position horizontal to the plane of a table. The string comes in contact with a peg some distance below the point where the string is attached at the top. One is asked to find what minimum fraction of the string's length should the peg be placed to have the mass complete a circle about the peg. However, when the mass is released from much lower heights, the system undergoes periodic motion that can be thought of as an interrupted pendulum.

  19. Periodicity of the stable isotopes

    CERN Document Server

    Boeyens, J C A

    2003-01-01

    It is demonstrated that all stable (non-radioactive) isotopes are formally interrelated as the products of systematically adding alpha particles to four elementary units. The region of stability against radioactive decay is shown to obey a general trend based on number theory and contains the periodic law of the elements as a special case. This general law restricts the number of what may be considered as natural elements to 100 and is based on a proton:neutron ratio that matches the golden ratio, characteristic of biological and crystal growth structures. Different forms of the periodic table inferred at other proton:neutron ratios indicate that the electronic configuration of atoms is variable and may be a function of environmental pressure. Cosmic consequences of this postulate are examined. (author)

    Nonlinear periodic drift waves are investigated on the basis of a simple perturbation scheme for both the amplitude and inverse frequency. The coefficients for the generation of the forced harmonics are derived, a nonlinear dispersion relation is suggested and a criterion for the onset of the modulational instability is obtained. The results are compared with the ones obtained with the help of a standard KBM-treatment. Moreover cnoidal drift waves are suggested and compared to an experimental observation. (orig.)

    It has been discussed whether the relationship between a patient on sick leave and his/her general practitioner (GP) is too close, as this may hinder the GP's objective evaluation of need for sick leave. Independent medical evaluation involves an independent physician consulting the patient. This could lead to new perspectives on sick leave and how to follow-up the patient. The current study is a randomized controlled trial in a Norwegian primary care context, involving an effect evaluation, a cost/benefit analysis, and a qualitative evaluation. Independent medical evaluation will be compared to treatment as usual, i.e., the physicians' and social insurance agencies' current management of long-term sick-listed patients. Individuals aged 18-65 years, sick listed by their GP and on full or partial sick leave for the past 6 months in Hordaland county will be included. Exclusion criteria are pregnancy, cancer, dementia or an ICD-10 diagnosis. A total sample of 3800 will be randomly assigned to either independent medical evaluation or treatment as usual. Official register data will be used to measure the primary outcome; change in sickness benefits at 7, 9 and 12 months. Sick listed in other counties will serve as a second control group, if appropriate under the "common trend" assumption. The Norwegian effect evaluation of independent medical evaluation after 6 months sick leave is a large randomized controlled trial, and the first of its kind, to evaluate this type of intervention as a means of getting people back to work after long-term sickness absence.

    Stroke incidence in high-income countries is reported to decrease, and new data on stroke incidence and outcome are needed to design stroke services and to ameliorate stroke management. This study is part of a two-year prospective community-based registry of all cerebrovascular events in the district of Udine (153,312 inhabitants), Friuli-Venezia Giulia region, northeast of Italy, between 1 April 2007 and 31 March 2009. Overlapping sources for case finding were used, combining hot and cold pursuit. We identified 784 stroke cases, 640 (81.6%) incident. The crude overall annual incidence rate per 100,000 residents was 256 (95% confidence interval 241-271) for all strokes and 209 (95% confidence interval 195-223) for first-ever strokes. Incidence rate for first-ever strokes was 181 (95% confidence interval 155-211) after adjustment to the 2007 Italian population and 104 (95% confidence interval 88-122) compared with the European standard population. Incidence rates for first-ever strokes was 215 (196-235) for women, 202 (183-223) for men. Crude annual incidence rates per 100,000 population were 167 (153-178) for ischemic stroke, 31 (26-37) for intracerebral hemorrhage, 8.1 (5.7-11.4) for sub-arachnoid hemorrhage, and 4.6 (2.8-7.1) for undetermined stroke. Overall case fatality rates for first-ever stroke were 20.6% at 28 days and 30.2% at 180 days. Our study shows incidence rates higher than previously reported in our region but not supporting the view of higher incidence rates in Northern than in Southern Italy. Results contribute to time-trends analysis on epidemiology, useful for dimensioning services in Italy and show the persistence of a gap between the outcome of stroke in Italy and that of the best performing European countries, urging to adopt better stroke management plans. © 2013 The Authors.

    The increasing rate of health care expenditures in the United States has placed a significant burden on the nation's economy. Predicting future health care utilization of patients can provide useful information to better understand and manage overall health care deliveries and clinical resource allocation. This study developed an electronic medical record (EMR)-based online risk model predictive of resource utilization for patients in Maine in the next 6 months across all payers, all diseases, and all demographic groups. In the HealthInfoNet, Maine's health information exchange (HIE), a retrospective cohort of 1,273,114 patients was constructed with the preceding 12-month EMR. Each patient's next 6-month (between January 1, 2013 and June 30, 2013) health care resource utilization was retrospectively scored ranging from 0 to 100 and a decision tree-based predictive model was developed. Our model was later integrated in the Maine HIE population exploration system to allow a prospective validation analysis of 1,358,153 patients by forecasting their next 6-month risk of resource utilization between July 1, 2013 and December 31, 2013. Prospectively predicted risks, on either an individual level or a population (per 1000 patients) level, were consistent with the next 6-month resource utilization distributions and the clinical patterns at the population level. Results demonstrated the strong correlation between its care resource utilization and our risk scores, supporting the effectiveness of our model. With the online population risk monitoring enterprise dashboards, the effectiveness of the predictive algorithm has been validated by clinicians and caregivers in the State of Maine. The model and associated online applications were designed for tracking the evolving nature of total population risk, in a longitudinal manner, for health care resource utilization. It will enable more effective care management strategies driving improved patient outcomes.

    Recent studies have strengthened the claim that repetitive transcranial magnetic stimulation (rTMS) is an effective treatment for major depression. The longitudinal outcome of TMS-treated patients, however, has not been described. We report on the 3- and 6-month outcomes of a group of patients treated with either electroconvulsive therapy (ECT) (n = 20) or (rTMS) (n = 21). Patients diagnosed with major depressive disorder with or without psychotic features referred for ECT were randomly assigned to receive either ECT or rTMS. Forty-one patients who responded to either treatment constituted the sample. Patients were followed on a monthly basis and outcomes were determined with the Hamilton Rating Scale for Depression-17 items (HRSD) and the Global Assessment of Functioning (GAF) scales. Medications were routinely prescribed. There were no differences in the 6-month relapse rate between the groups. Overall, 20% of the patients relapsed (four from the ECT group and four from the rTMS group). Patients reported equally low and not significantly different scores in the HRSD (ECT group 8.4 +/- 5.6 and TMS group 7.9 +/- 7.1) and the GAF (ECT group 72.8 +/- 12 and TMS group 77.8 +/- 17.1) at the 6-month follow up. Patients treated with rTMS do as well as those treated with ECT at the 3- and 6-month follow-up points. These data suggest that the clinical gains obtained with rTMS last at least as long as those obtained with ECT.

    2016-06-15

    Purpose: To investigate the correlation between different dosimetric indices of salivary glands (as separate or combined structures) to patient-reported dry mouth 6 months post radiotherapy using the novel patient reported outcome version of the CTCAE (PRO-CTCAE). Methods: Forty-three patients with oropharyngeal squamous cell carcinoma were treated on a prospective multi-institutional study. All patients received de-intensified 60 Gy intensity modulated radiotherapy. Dosimetric constraints were used for the salivary glands (e.g. mean dose to the contralateral-parotid < 26 Gy). We investigated correlations of individual patient dosimetric data of the parotid and submandibular glands (as separate or combined structures) to their self-reported 6 month post-treatment dry mouth responses. Moderate dry mouth responses were most prevalent and were used as the clinical endpoint indicating response. The correlation of Dmean, Dmax and a range of dosevolume (VD) points were assessed through the area under the Receiver Operating Characteristic curve (ROC) and Odds Ratios (OR). Results: Patients reporting non/mild dry mouth response (N=22) had average Dmean = 19.6 ± 6.2Gy to the contralateral-parotid compared to an average Dmean = 28.0 ± 8.3Gy and an AUC = 0.758 for the patients reporting moderate/severe/very severe dry mouth (N=21). Analysis of the range of VD’s for patients who had reported dry mouth showed that for the contralateral-parotid the indices V18 through V22 had the highest area under the curves (AUC) (0.762 – 0.772) compared to a more traditional dosimetric index V30, which had an AUC = 0.732. The highest AUC was observed for the combination of contralateral parotid and contralateral submandibular glands, for which V16 through V28 had AUC = 0.801 – 0.834. Conclusion: Patients who report moderate/severe/very severe dry mouth 6 months post radiotherapy had on average higher Dmean. The V16-V28 of the combination of the contralateral glands showed the highest correlation with the clinical endpoint.

    Purpose: To estimate the radiobiological parameters of four popular NTCP models that describe the dose-response relations of salivary glands to the severity of patient reported dry mouth 6 months post chemo-radiotherapy. To identify the glands, which best correlate with the manifestation of those clinical endpoints. Finally, to evaluate the goodness-of-fit of the NTCP models. Methods: Forty-three patients were treated on a prospective multiinstitutional phase II study for oropharyngeal squamous cell carcinoma. All the patients received 60 Gy IMRT and they reported symptoms using the novel patient reported outcome version of the CTCAE. We derived the individual patient dosimetric data of the parotid and submandibular glands (SMG) as separate structures as well as combinations. The Lyman-Kutcher-Burman (LKB), Relative Seriality (RS), Logit and Relative Logit (RL) NTCP models were used to fit the patients data. The fitting of the different models was assessed through the area under the receiver operating characteristic curve (AUC) and the Odds Ratio methods. Results: The AUC values were highest for the contralateral parotid for Grade ≥ 2 (0.762 for the LKB, RS, Logit and 0.753 for the RL). For the salivary glands the AUC values were: 0.725 for the LKB, RS, Logit and 0.721 for the RL. For the contralateral SMG the AUC values were: 0.721 for LKB, 0.714 for Logit and 0.712 for RS and RL. The Odds Ratio for the contralateral parotid was 5.8 (1.3–25.5) for all the four NTCP models for the radiobiological dose threshold of 21Gy. Conclusion: It was shown that all the examined NTCP models could fit the clinical data well with very similar accuracy. The contralateral parotid gland appears to correlated best with the clinical endpoints of severe/very severe dry mouth. An EQD2Gy dose of 21Gy appears to be a safe threshold to be used as a constraint in treatment planning.

    Several studies have shown that alpha-ketoglutaric acid (AKG) increases serum levels of proline and has beneficial effects on skeletal development. We studied the effect of alpha-ketoglutaric (AKG) acid calcium salt (6 g AKG and 1.68 Ca/day) or calcium alone (1.68 Ca/day) on serum C-terminal cross-linked telopeptide of type I collagen (CTX) and osteocalcin (OC), as well as on lumbar spine bone mineral density (BMD) in a randomized, parallel group, double-blind, 6-month study conducted on 76 postmenopausal women with osteopenia. The maximum decrease of the mean CTX level in the AKG-Ca group was observed after 24 weeks (37.0%, p = 0.006). The differences in CTX between study groups were statistically significant after 12 and 24 weeks. The OC serum level was not affected by treatments. The BMD of the AKG-Ca group increased by 1.6% from baseline; however, the difference between treatment groups was estimated as 0.9% (non-significant). This study suggests the potential usefulness of AKG-Ca in osteopenic postmenopausal women. AKG-Ca induced beneficial changes in serum CTX, which was consistent with preserving the bone mass in the lumbar spine; however, the long-term effect needs to be further investigated.

    Protein energy malnutrition predisposes individuals to disease, delays recovery from illness and reduces quality of life. Care home residents are especially vulnerable, with an estimated 30%-42% at risk. There is no internationally agreed protocol for the nutritional treatment of malnutrition in the care home setting. Widely used techniques include food-based intervention and/or the use of prescribed oral nutritional supplements, but a trial comparing the efficacy of interventions is necessary. In order to define outcomes and optimise the design for an adequately powered, low risk of bias cluster randomised controlled trial, a feasibility trial with 6-month intervention is being run, to assess protocol procedures, recruitment and retention rates, consent processes and resident and staff acceptability. Trial recruitment began in September 2013 and concluded in December 2013. Six privately run care homes in Solihull, England, were selected to establish feasibility within different care home types. Residents with or at risk of malnutrition with no existing dietetic intervention in place were considered for receipt of the allocated intervention. Randomisation took place at the care home level, using a computer-generated random number list to allocate each home to either a dietetic intervention arm (food-based or prescribed supplements) or the standard care arm, continued for 6 months. Dietetic intervention aimed to increase daily calorie intake by 600 kcal and protein by 20-25 g. The primary outcomes will be trial feasibility and acceptability of trial design and allocated interventions. A range of outcome assessments and data collection tools will be evaluated for feasibility, including change in nutrient intake, anthropometric parameters and patient-centric measures, such as quality of life and self-perceived appetite. The complexities inherent in care home research has resulted in the under representation of this population in research trials. The results of this feasibility trial will be used to inform the development and design of a future cluster randomised controlled trial to compare food-based intervention with prescribed oral nutritional supplements (ONS) in the treatment of malnutrition within the care home population.

    The major objective of this study was to relate the results of a series of functional tests to the compositional and structural alterations in the rat lung induced by subchronic exposure to silica dust. Fischer-344 rats were exposed for 6 hours/day, 5 days/week for 6 months to either 0, 2, 10, or 20 mg SiO{sub 2}/m{sup 3}. The general appearance of the exposed rats was not different from that of the controls. Interestingly, female rats exposed to silica dust, at all tested concentrations, gained more weight than the controls. The lung weight and the lung-to-body weight ratio was greater in the male rats exposed to the highest concentration of silica dust.

    Electronic cigarettes (e-cigarettes) are being used as cessation aids by many smokers despite a lack of empirical evidence regarding their safety and efficacy. We analyzed the association of e-cigarette use and smoking abstinence in a population of smokers accessing standard smoking cessation treatment (nicotine replacement therapy [NRT] plus behavioral counseling) through primary care clinics in Ontario, Canada. Participants were recruited through 187 primary care clinics across Ontario, Canada and were eligible for up to 26 weeks of brief behavioral counseling and individualized dosing of NRT at no cost. Adjusted logistic regression models were used to examine the association between concurrent e-cigarette use and smoking abstinence at 3- and 6-month follow-ups. Of the 6526 participants who completed a 3-month follow-up, 18.1% reported using an e-cigarette while in treatment. The majority of e-cigarette users (78.2%) reported using an e-cigarette for smoking cessation. At 3-month follow-up, e-cigarette use was negatively associated with abstinence after controlling for confounders (adjusted odds ratio [AOR] = 0.706, p E-cigarette use was also negatively associated with abstinence at 6-month follow-up (AOR = 0.502, p E-cigarette use was negatively associated with successful quitting in this large community sample of smokers accessing standard evidence-based smoking cessation treatment through primary care clinics, even after adjusting for covariates such as severity of tobacco dependence, gender, and age. The findings suggest that concurrent use of e-cigarettes with NRT may harm cessation attempts. This study confirms previous findings from observational studies regarding the negative association between e-cigarette use and smoking cessation, but in a large cohort of smokers enrolled in an evidence-based treatment program. The implications of these findings are that concurrent use of e-cigarettes during a quit attempt utilizing cost-free evidence-based treatment (NRT plus behavioral counseling) does not confer any added benefit and may hamper successful quitting. © The Author 2016.

    Being a close relative brings with it a large number of consequences, with the life situation changing over time. The aim of this study was to illuminate the experiences of being a middle-aged close relative of a person who has suffered a stroke 6 months after being discharged from a medical rehabilitation clinic. Narrative interviews were conducted with nine middle-aged close relatives and analysed using a content analysis with a latent approach. The analysis revealed that being close to someone who had suffered a stroke 6 months after discharge meant; a struggling for control and a renewal of family life in the shadow of suffering and hope. The middle-aged close relatives began to perceive the changed reality. They were struggling to take on something new, become reconciled and find a balance in their family life. Their ability to work, relief from caring concerns and having support and togetherness with others seemed to be essential for the close relatives in their efforts to manage their life situation and maintain their well-being. Having reached the 'halfway point' in their lives and still with half of their life in front of them created worries. They felt dejected about their changed relationships and roles, experience a sense of loss of shared child responsibilities, a negative impact on their marital relationships and sexual satisfaction. They felt trapped in a caring role and they worried about how to endure in the future. The middle-aged close relatives' experiences were of being alone and neglected, in an arduous and complex life situation filled with loss and grief. The findings highlights that health professionals need to see and listen to the close relatives' experiences of transition in order to provide appropriate support adjusted to their varying needs during a time of renewal.

    This prospective, randomized, open-label multicenter trial evaluated the efficacy of catheter-based renal denervation (Symplicity, Medtronic) versus intensified pharmacological treatment including spironolactone (if tolerated) in patients with true-resistant hypertension. This was confirmed by 24-hour ambulatory blood pressure monitoring after excluding secondary hypertension and confirmation of adherence to therapy by measurement of plasma antihypertensive drug levels before enrollment. One-hundred six patients were randomized to renal denervation (n=52), or intensified pharmacological treatment (n=54) with baseline systolic blood pressure of 159±17 and 155±17 mm Hg and average number of drugs 5.1 and 5.4, respectively. A significant reduction in 24-hour average systolic blood pressure after 6 months (-8.6 [95% cofidence interval: -11.8, -5.3] mm Hg; Pblood pressure (-12.4 [95% cofidence interval: -17.0, -7.8] mm Hg; Pblood pressure comparable with intensified pharmacotherapy. © 2014 American Heart Association, Inc.

    Pioglitazone has been reported to improve common cardiovascular risk factors in addition to glycemic control in patients with type 2 diabetes mellitus (T2DM). The changes in cardiovascular risk profile were evaluated comparatively in large cohorts either treated or not with pioglitazone-containing combinations in the current clinical setting within Spain. A nationwide prospective, controlled, observational cohort clinical study was performed in 2294 patients with T2DM who started, at the criterion of the treating physician, oral antihyperglycemic treatment with either pioglitazone plus a sulfonylurea (Pio+SU; n=851), pioglitazone plus metformin (Pio+Met; n=723) or a sulfonylurea plus metformin (SU+Met; n=720) due to inadequate control with previous therapy. Serum cholesterol, blood glucose, hemoglobin A1C, blood pressure and certain anthropometric parameters were measured at baseline and after 6 months of treatment. Serum high density lipoprotein-cholesterol increased in average (mg/dl) 2.08 with Pio+SU, 2.06 with Pio+Met and 0.67 with SU+Met; while triglycerides decreased (mg/dl) 26.6, 30.6 and 17.6 in the same cohorts. Inter-group differences were significant (p<0.001 in both parameters). Total cholesterol decreased significantly more with SU+Met than in the pioglitazone cohorts. Mean fasting plasma glucose and hemoglobin A1C reductions were significantly greater in the pioglitazone cohorts than in the SU+Met cohort: 27.74, 28.94 and 23.46 mg/dl (p=0.012); and 0.80, 0.87 and 0.71% (p=0.016) with Pio+SU, Pio+Met and SU+Met, respectively. Slight, but significant variations of body weight were also registered in the Pio+SU (+1.4 kg) and SU+Met (-0.7 kg) groups. Treatment with pioglitazone was associated with significant improvements of lipid and glycemic parameters that are linked to insulin resistance and cardiovascular risk in patients with T2DM in their routine clinical care. The non-randomised allocation of patients to treatments, inherent to its observational design, is an important limitation of the present study.

    Full Text Available Toxic epidermal necrolysis is the life-threatening dermatological emergency, most often an adverse cutaneous drug reaction with high mortality. A 6-month prospective study was conducted in our institution to find out the offending drugs, to assess the prognosis on admission using SCORTEN: Severity of illness score and to find out the treatment outcome. Anticonvulsants, NSAIDs and sulphonamides are the common offending agents; but in our study, 2 were due to homeopathic medicines. Out of 20 patients, on the date of admission SCORTEN prognostic score was 2 in 11 patients, 3 in 8 patients and 4 in 1 patient. Eighteen patients were treated with dexamethasone intramuscular injection and 2 patients got intravenous immunoglobulin (IVIG. All patients survived without any mortality. Though improvement was slightly faster with IVIG, early administration of corticosteroids was also of encouraging efficacy and should be considered in developing countries due to low cost. No mortality in our study suggests need to validate the SCORTEN index in our country in a large number of patients.

    In many resource-limited settings, emergency medicine (EM) is underdeveloped and formal EM training limited. Residencies and fellowships are an ideal long-term solution but cannot meet immediate needs for emergency providers, while short-term programs are often too limited in content. We describe a third method successfully implemented in Haiti: a medium-duration certificate program to meet the immediate need for emergency specialists. In conjunction with the Haitian Ministry of Health and National Medical School, we developed and implemented a novel, 6-month EM certificate program to build human resources for health and emergency care capacity. The program consisted of didactic and supervised clinical components, covering core content in EM. Didactics included lectures, simulations, hands-on skill-sessions, and journal clubs. Supervised clinical time reinforced concepts and taught an EM approach to patient care. Fourteen physicians from around Haiti successfully completed the program; all improved from their pre-test to post-test. At the end of the program and 9-month post-program evaluations, participants rated the program highly, and most felt they used their new knowledge daily. Participants found clinical supervision and simulation particularly useful. Key components to our program's success included collaboration with the Ministry of Health and National Medical School, supervised clinical time, and the continual presence of a course director. The program could be improved by a more flexible curriculum and by grouping participants by baseline knowledge levels. Medium-duration certificate programs offer a viable option for addressing immediate human resource gaps in emergency care, and our program offers a model for implementation in resource-limited settings. Similar options should be considered for other emerging specialties in resource-limited settings.

    EMPOWER-H (Engaging and Motivating Patients Online With Enhanced Resources-Hypertension) is a personalized-care model facilitating engagement in hypertension self-management utilizing an interactive Web-based disease management system integrated with the electronic health record. The model is designed to support timely patient-provider interaction by incorporating decision support technology to individualize care and provide personalized feedback for patients with chronic disease. Central to this process were patient-generated health data, including blood pressure (BP), weight, and lifestyle behaviors, which were uploaded using a smartphone. The aim of this study was to evaluate the program among patients within primary care already under management for hypertension and with uncontrolled BP. Using a 6-month pre-post design, outcome measures included office-measured and home-monitored BP, office-measured weight, intervention contacts, diet, physical activity, smoking, knowledge, and health-related quality of life. At 6 months, 55.9% of participants (N=149) achieved office BP goals (total intervention, behavioral, pharmaceutical contacts had significantly lower odds of achieving home BP goals but higher improvements in office BP (all Pmanagement. The experience gained in this study provides support for the feasibility and value of using carefully managed patient-generated health data in the day-to-day clinical management of patients with chronic conditions. A large-scale, real-world study to evaluate sustained effectiveness, cost-effectiveness, and scalability is warranted. ©Nan Lv, Lan Xiao, Martha L Simmons, Lisa G Rosas, Albert Chan, Martin Entwistle.

    According to a recent report from the European Brain Council and the European Colleague of Neuropsychopharmacology the one year prevalence of some kind of mental disorder is around 27% among the adult population in Europe. Research has shown a lack of mental health literacy in the population in general and it is thus important to find ways to improve the public's knowledge and skills to provide first hand support to people with mental disorders. Mental Health First Aid (MHFA) is a training program that has shown positive changes in knowledge and helping behavior. This study investigates if MHFA training in a Swedish context provides a sustained improvement in knowledge about mental disorders, a better ability to be helpful in contacts with people who are ill and if it changes attitudes in a positive direction. The introduction of the training program was made in accordance with the constructor's instructions. Participants were mainly public sector employees from a county in the west of Sweden. The study was a randomized controlled trial with an experiment group (n = 199) and a control group (n = 207) placed on a waiting list during a 6-month follow-up. A two-year follow-up was conducted for participants (n = 155) from both the intervention and waiting list group who had completed the training and during the follow-up been in contact with persons with mental disorders. The intervention group improved in knowledge as well as in confidence in providing help for someone in need. The two-year follow-up showed that the improvements were to a great extent maintained. Mental Health First Aid might raise the level of awareness of mental disorders and have an influence on the number of people who can receive professional treatment for their problems.

    To assess weight and metabolic effects of 6 months of treatment with second-generation antipsychotics in naïve/quasi-naïve youths. This study looked at a nonrandomized, naturalistic, multicenter, inception cohort study of 279 patients aged 4 to 17 years (mean = 14.6 ± 2.9 years). Of those, 248 (88.8%) received a single antipsychotic (risperidone, olanzapine, or quetiapine) and completed 2 visits, and 178 (63.8%) completed the 6-month follow-up. Patients had schizophrenia-spectrum disorders (44.5%), mood-spectrum disorders (23.2%), disruptive behavioral disorders (17.3%), or other disorders (15.1%). Fifteen age- and gender-matched, healthy, nonmedicated individuals served as a comparison group. From baseline to 1 month, 3 months, and 6 months, all anthropometric measures increased significantly with each antipsychotic, that is, 6-month changes with risperidone (n = 157; 7.1 kg and 0.66 body mass index [BMI] z score), olanzapine (n = 44; 11.5 kg and 1.08 BMI z score), and quetiapine (n = 47; 6.3 kg and 0.54 BMI z score), but not in healthy control participants (-0.11 kg and 0.006 BMI z score). Fasting metabolic parameters increased significantly with risperidone (glucose [3.8] mg/dL, insulin [4.9] mU/L, homeostasis model assessment of insulin resistance [HOMA-IR: 1.2], triglycerides [15.6] mg/dL), and olanzapine (glucose [5.0] mg/dL, total cholesterol [21.2] mg/dL, and low-density lipoprotein cholesterol [44.6] mg/dL), but not with quetiapine or in healthy control participants. The percentage of research participants considered to be "at risk of adverse health outcome" increased during the 6 months from 8.9% to 29.2% for risperidone (p < .0001), 6.8% to 38.1% for olanzapine (p < .0001), and 6.3% to 4.0% for quetiapine (p = .91). Olanzapine, quetiapine, and risperidone increase body weight but have different cardiometabolic side effect profiles and different temporal side effect patterns.

    The authors compared the safety and efficacy of a newly developed fast-track concept at their center, including implementation of a direct admission postanesthetic care unit, to standard perioperative management. All fast-track patients treated within the first 6 months of implementation of our direct admission postanesthetic care unit were matched via propensity scores and compared with a historical control group of patients who underwent cardiac surgery prior to fast-track implementation. A total of 421 fast-track patients were matched successfully to 421 control patients. The two groups of patients had a similar age (64 +/- 13 vs. 64 +/- 12 yr for fast-track vs. control, P = 0.45) and European System for Cardiac Operative Risk Evaluation-predicted risk of mortality (4.8 +/- 6.1% vs. 4.6 +/- 5.1%, P = 0.97). Fast-track patients had significantly shorter times to extubation (75 min [45-110] vs. 900 min [600-1140]), as well as shorter lengths of stay in the postanesthetic or intensive care unit (4 h [3.0-5] vs. 20 h [16-25]), intermediate care unit (21 h [17-39] vs. 26 h [19-49]), and hospital (10 days [8-12] vs. 11 days [9-14]) (expressed as median and interquartile range, all P operations.

    Full Text Available According to a recent report from the European Brain Council and the European Colleague of Neuropsychopharmacology the one year prevalence of some kind of mental disorder is around 27% among the adult population in Europe. Research has shown a lack of mental health literacy in the population in general and it is thus important to find ways to improve the public's knowledge and skills to provide first hand support to people with mental disorders. Mental Health First Aid (MHFA is a training program that has shown positive changes in knowledge and helping behavior. This study investigates if MHFA training in a Swedish context provides a sustained improvement in knowledge about mental disorders, a better ability to be helpful in contacts with people who are ill and if it changes attitudes in a positive direction.The introduction of the training program was made in accordance with the constructor's instructions. Participants were mainly public sector employees from a county in the west of Sweden. The study was a randomized controlled trial with an experiment group (n = 199 and a control group (n = 207 placed on a waiting list during a 6-month follow-up. A two-year follow-up was conducted for participants (n = 155 from both the intervention and waiting list group who had completed the training and during the follow-up been in contact with persons with mental disorders. The intervention group improved in knowledge as well as in confidence in providing help for someone in need. The two-year follow-up showed that the improvements were to a great extent maintained.Mental Health First Aid might raise the level of awareness of mental disorders and have an influence on the number of people who can receive professional treatment for their problems.

    Full Text Available Type D personality and medication nonadherence have been shown to be associated with poor health outcomes. Type D personality is associated with poor medication adherence in patients with coronary artery disease, myocardial infarction, and heart failure. However, the relationship between type D personality and medication adherence in patients with Type 2 Diabetes Mellitus (T2DM remains unknown. This study aims to examine whether type D personality was associated with medication adherence in patients with T2DM.A follow-up study was conducted in general hospital of the People's Liberation Army in Beijing.412 T2DM patients (205 females, who were recruited by circular systematic random sampling, provided demographic and baseline data about medical information and completed measures of Type D personality. Then, 330 patients went on to complete a self-report measure of medication adherence at the sixth month after baseline data collection. Chi-square test, t tests, and hierarchical multiple regression analyses were conducted, as needed.Patients with type D personality were significantly more likely to have poor medication adherence (p<0.001. Type D personality predicts poor medication adherence before and after controlling for covariates when it was analyzed as a categorical variable. However, the dimensional construct of type D personality was not associated with medication adherence when analyzed as a continuous variable.Although, as a dimensional construct, type D personality may not reflect the components of the personality associated with poor medication adherence in patients with T2DM, screening for type D personality may help to identify those who are at higher risk of poor medication adherence. Interventions, aiming to improve medication adherence, should be launched for these high-risk patients.

    The effect of aerobic exercise on physical function and mental health in various adult age groups (young-old, 65-74; old-old, 75-84; oldest-old, ≥ 85 years) is unclear. The aim of this study was to investigate the effects of the Kohzuki Exercise Program (KEP) on physical function and mental health in these age groups. The KEP consisted of 40-min supervised sessions 3 times per week for 6 months as follows: 5 min of warm-up, 30 min of lower limb aerobic exercise, and 5 min of cool-down. A total of 50 participants (22 young-old, 20 old-old, and 8 oldest-old) who participated in the KEP completed at least 88% of the sessions. In statistical analysis, 3 (group: oldest-old, old-old, young-old) × 2 (time: baseline and after 6 months) analyses of variance were used to determine if there were significant main and interaction effects. Significant interactions were probed using the post-hoc paired t test. The Short Physical Performance Battery (SPPB) score showed significant group × time interactions after 6 months (p = 0.031). In the post-hoc test, oldest-old (p health measures showed group × time interactions at 6-month. Our results suggest that a 6-month KEP led to improved physical function in oldest-old, old-old, and young-old adults. The KEP was effective for oldest-old adults in particular. The KEP exhibits good adherence, making it suitable for a wide age range in society.

    2012-01-01

    Background Chemoprevention crossover trials of tea can be more efficient than parallel designs but the attrition and compliance rates with such trials are unknown. Methods Attrition (dropouts) and compliance with treatment were assessed in a 25-week randomized, placebo controlled, crossover, feasibility clinical trial of four tea treatments to investigate the effect of tea on oral cancer biomarkers. Each treatment lasted 4 weeks with 2 weeks of washout in between. Participants were 32 smokers and 33 non-smokers without any evidence of premalignant oral lesions. The interventions consisted of packets of green tea, black tea, caffeinated water, or placebo. Participants were assigned to each treatment for four weeks, and were instructed to drink five packets per day while on the treatment. Dropout from the trial and compliance (consumption of ≥ 85% of the prescribed treatment packets) are the main outcome measures reported. Results There was a high rate of dropout (51%) from the study, and the rates were significantly higher among smokers (64%) than non-smokers (36%). Among participants who completed the study the rate of compliance was 72%. The highest rates of dropouts occurred between the first and second treatment visits in both smokers (38% dropout) and non-smokers (18% dropout). Throughout the study smokers were more likely to dropout than non-smokers. Black tea treatment was associated with the highest rates of dropout among smokers (37%), but was associated with the lowest rate of dropout among non-smokers (4%). Conclusions In a study conducted to test the feasibility of a four-treatment crossover tea trial, a high rate of dropout among smokers and non-smokers was observed. Multi-arm crossover tea trials might pose a higher burden on participants and research is needed to improve adherence and treatment compliance in such trials.

    Spontaneous coronary artery dissections (SCAD) are often difficult to diagnose and manage. Intravascular imaging such as optical coherence tomography (OCT) improves diagnosis and may assist in management. Recent data suggest that percutaneous coronary interventions (PCI) in in SCAD are associated with poor outcomes. This report provides striking OCT images of potential complications associated with PCI in SCAD, as well as demonstrates medium term OCT data in residual hematoma healing and stent coverage in SCAD.

    Breastfeeding is one of the top maternal priorities for many organizations, including the World Health Organization (WHO), The American Academy of Pediatrics (AAP), and the Center for Disease Control (CDC). Focusing on the goals of Healthy People 2020, as well as the recommendations of other organizations, this paper investigates the impacts on women's intentions to breastfeed newborns for 3 months, 6 months, and 1 year. This research used the theory of planned behavior (TPB) as a model to predict intentions for each duration of time. Body satisfaction was included as a moderating variable given research demonstrating a possible connection of body satisfaction to breastfeeding. A survey of 156 pregnant women was conducted. Results demonstrated the importance of the three TPB measures in predicting intentions. Further, significant interactions between body satisfaction and attitudes, as well as body satisfaction and subjective norms were present in predicting intentions to exclusively breastfeed one's baby from infant to 6 months of age. Theoretical implications are discussed, as well as practical implications for breastfeeding interventions and campaigns.

    Australian and New Zealand health authorities identified seasonal trivalent inactivated influenza vaccines manufactured by CSL Biotherapies as the probable cause of increased febrile convulsions in children under five within 24 hours of vaccination and recommended against their use in this age group. We quantified the benefit-risk profile of the CSL vaccines using the number needed to vaccinate and suggest they might have caused two to three hospital admissions due to febrile convulsions for every hospital admission due to influenza prevented.

    Full Text Available OBJECTIVES: To longitudinally assess bone mineral content (BMC, bone mineral density (BMD, and whole-body lean mass obtained through bone densitometry by dual-energy X-ray absorptiometry (DXA in preterm newborns (PTNs and compare them with full-term newborns (FTNs from birth to 6 months of corrected postnatal age. METHODS: A total of 28 adequate for gestational age (AGA newborns were studied: 14 preterm and 14 full-term newborns. DXA was used to determine BMC, BMD, and lean mass in three moments: 40 weeks corrected post-conceptual age, as well as 3 and 6 months of corrected postnatal age. PTNs had gestational age ≤ 32 weeks at birth and were fed their mother's own milk or milk from the human milk bank. RESULTS: All infants had an increase in BMC, BMD, and lean body mass values during the study. PTNs had lower BMC, BMD, and lean mass at 40 weeks of corrected post-conceptual age in relation to FTNs (p < 0.001, p < 0.001, p = 0.047, respectively. However, there was an acceleration in the mineralization process of PTNs, which was sufficient to achieve the normal values of FTNs at 6 months of corrected age. CONCLUSIONS: This study suggests that bone densitometry by dual-energy X-ray absorptiometry is a good method for the assessment of body composition parameters at baseline, and at the follow-up of these PTNs.

    to compare the clinical conditions of obese patients in the pre and postoperative period of bariatric surgery. we carried out a descriptive, retrospective, quantitative study by consulting the charts of 134 patients who underwent bariatric surgery in the period from 2009 to 2014. We collected the data between September and November 2015. We performed a descriptive statistical analysis and comparative analysis of anthropometric, metabolic, biochemical and clinical variables, considering six months before and after surgery. the majority of the patients were female (91.8%), with a higher prevalence (35%) in the age group 18-29 years old, complete high-school education (65.6%) and grade III obesity (60.4%). Six months after surgery, weight and lipid profile reduction were significant in both genders, but the impact on biochemical, anthropometric, metabolic and clinical parameters was significant only in female subjects, with a reduction in morbidities associated with obesity, such as arterial hypertension, diabetes mellitus, dyslipidemia and metabolic syndrome and in the use of drugs to control them. bariatric surgery was effective in weight loss, with improvements in anthropometric, metabolic and biochemical parameters and in the reduction of morbidities associated with obesity. comparar as condições clínicas de pacientes obesos em período pré e pós-operatório de cirurgia bariátrica. estudo descritivo, retrospectivo, de abordagem quantitativa, por meio de consulta ao prontuário de 134 pacientes submetidos à cirurgia bariátrica no período de 2009 a 2014.

  2. Long-Period Solar Variability

    GAUTHIER,JOHN H.

    2000-07-20

    Terrestrial climate records and historical observations of the Sun suggest that the Sun undergoes aperiodic oscillations in radiative output and size over time periods of centuries and millenia. Such behavior can be explained by the solar convective zone acting as a nonlinear oscillator, forced at the sunspot-cycle frequency by variations in heliomagnetic field strength. A forced variant of the Lorenz equations can generate a time series with the same characteristics as the solar and climate records. The timescales and magnitudes of oscillations that could be caused by this mechanism are consistent with what is known about the Sun and terrestrial climate.

    The time–frequency analysis of a signal is often performed via a series expansion arising from well-localized building blocks. Typically, the building blocks are based on frames having either Gabor or wavelet structure. In order to calculate the coefficients in the series expansion, a dual frame...... is needed. The purpose of the present paper is to provide constructions of dual pairs of frames in the setting of the Hilbert space of periodic functions L2(0,2π). The frames constructed are given explicitly as trigonometric polynomials, which allows for an efficient calculation of the coefficients...

    This paper deals with state-dependent open Markovian (or exponential) queuing networks, for which arrival and service rates, as well as routing probabilities, may depend on the queue lengths. For a network of this kind, following Mandelbaum and Pats, we provide a formal definition of its associated fluid model, and we focus on the relationships which may occur between the network stochastic dynamics and the deterministic dynamics of its corresponding fluid model, particularly focusing on queuing networks whose fluid models have global periodic attractors.

    Bone disease contributes to relevant morbidity after solid organ transplantation. Vitamin D has a crucial role for bone metabolism. Activation of vitamin D depends on the endocrine function of both, liver and kidney. Our study assessed key markers of bone metabolism at time of transplantation and 6 months after transplantation among 70 kidney and 70 liver recipients. In 70 kidney recipients 25-OH vitamin D levels did not differ significantly between peri-transplant (median 32.5nmol/l) and 6 months post-transplant (median 41.9nmol/l; P = 0.272). Six months post-transplant median 1, 25-(OH)2 vitamin D levels increased by >300% (from 9.1 to 36.5ng/l; Ptransplantation and of intact parathyroid hormone 6 months post-transplant. Among 70 liver recipients, 25-OH vitamin D, 1, 25-(OH)2 vitamin D and intact parathyroid hormone levels were not significantly altered between peri-transplant and 6 months post-transplant. Contrary to kidney recipients, median CTx increased by 60.0% (from 0.45 to 0.72 ng/ml; P = 0.002) and P1NP by 49.3% (from 84.0 to 125.4ng/ml; P = 0.001) in the longitudinal course. Assessed biomarkers didn't differ between liver recipients with and without fractures. To conclude, the assessed panel of biomarkers proved highly dynamic after liver as well as kidney transplantation in the early post-transplant period. After kidney transplantation a significant gain in 1, 25-(OH)2 vitamin D combined with a decline in iPTH, CTx and P1NP, whereas after liver transplantation an increase in CTx and P1NP were characteristic.

    To examine the influence of exercise on depressive symptoms and the prevalence of depression in the postpartum period. A structured search of MEDLINE, EMBASE, CINAHL, Sport Discus, Ovid's All EBM Reviews, and ClinicalTrials.gov databases was performed with dates from the beginning of the databases until June 16, 2016. The search combined keywords and MeSH-like terms including, but not limited to, "exercise," "postpartum," "depression," and "randomized controlled trial." Randomized controlled trials comparing postpartum exercise (structured, planned, repetitive physical activity) with the standard care for which outcomes assessing depressive symptoms or depressive episodes (as defined by trial authors) were assessed. Trials were identified as prevention trials (women from the general postpartum population) or treatment trials (women were classified as having depression by the trial authors). Effect sizes with 95% confidence intervals (CIs) were calculated using Hedges' g method and standardized mean differences in postintervention depression outcomes were pooled using a random-effects model. Across all 16 trials (1,327 women), the pooled standardized mean difference was -0.34 (95% CI -0.50 to -0.19, I=37%), suggesting a small effect of exercise among all postpartum women on depressive symptoms. Among the 10 treatment trials, a moderate effect size of exercise on depressive symptoms was found (standardized mean difference-0.48, 95% CI -0.73 to -0.22, I=42%). In six prevention trials, a small effect (standardized mean difference-0.22, 95% CI -0.36 to -0.08, I=2%) was found. In women with depression preintervention, exercise increased the odds of resolving depression postintervention by 54% (odds ratio 0.46, Mantel-Haenszel method, 95% CI 0.25-0.84, I=0%). The trials included in this meta-analysis were small and some had methodologic limitations. Light-to-moderate intensity aerobic exercise improves mild-to-moderate depressive symptoms and increases the likelihood that

    Variations in meteorological parameters are largely due to periodic processes and can be forecast for several years. Many such processes are related to astronomical factors such as the gravitational influences of the Moon and the Sun, and the modulation of solar irradiance by lunar and planetary motion. The Moon, Jupiter, and Venus have the strongest effect. These influences produce lines in the spectra of meteorological variations, which are combinations of the harmonics of the frequencies of revolution of the planets, the Earth, and the Moon around the Sun with the harmonics of the lunar revolution around the Earth. Due to frequency differences between the orbital and radial motions, fine spectral features of three types appear: line splitting, line-profile complications due to radial oscillations, and additional lines due to the combination of radial-oscillation frequencies with perturbation harmonics.

    The D-dimensional Coulomb system serves as a starting point for generating generalized atomic shells. These shells are ordered according to a generalized Madelung rule in D dimensions. This rule together with an Aufbau Prinzip is applied to produce a D-dimensional periodic table. A model is developed to rationalize the ordering of the shells predicted by the generalized Madelung rule. This model is based on the introduction of an Hamiltonian, invariant under the q-deformed algebra U q (so(D)), that breaks down the SO (D + 1) dynamical symmetry of the hydrogen atom in D dimensions. The D = 2 case (Flatland) is investigated with some details. It is shown that the neutral atoms and the (moderately) positive ions correspond to the values q = 0.8 and q = 1, respectively, of the deformation parameter q. (authors). 55 refs

  11. Periodic folding of viscous sheets

    Ribe, Neil M.

    2003-09-01

    The periodic folding of a sheet of viscous fluid falling upon a rigid surface is a common fluid mechanical instability that occurs in contexts ranging from food processing to geophysics. Asymptotic thin-layer equations for the combined stretching-bending deformation of a two-dimensional sheet are solved numerically to determine the folding frequency as a function of the sheet’s initial thickness, the pouring speed, the height of fall, and the fluid properties. As the buoyancy increases, the system bifurcates from “forced” folding driven kinematically by fluid extrusion to “free” folding in which viscous resistance to bending is balanced by buoyancy. The systematics of the numerically predicted folding frequency are in good agreement with laboratory experiments.

    2015-01-01

    Cancers exhibit differences in metastatic behavior and drug sensitivity that correlate with certain tumor-specific variables such as differentiation grade, growth rate/extent and molecular regulatory aberrations. In practice, patient management is based on the past results of clinical trials adjusted for these biomarkers. Here, it is proposed that treatment strategies could be fine-tuned upfront simply by quantifying tumorigenic spatial (cell growth) and temporal (genetic stability) control losses, as predicted by genetic defects of cell-cycle-regulatory gatekeeper and genome-stabilizing caretaker tumor suppressor genes, respectively. These differential quantifications of tumor dysfunction may in turn be used to create a tumor-specific 'periodic table' that guides rational formulation of survival-enhancing anticancer treatment strategies.

  13. Dynamical diffraction in periodic multilayers

    Sears, V F

    1997-01-01

    Exact reflectivity curves are calculated numerically for various periodic multilayers using the optical matrix method in order to test the dynamical theory of diffraction. The theory is generally valid for values of the bilayer thickness d up to about 100 A. For somewhat larger values of d, where the theory begins to break down, the initial discrepancy is in the phase of the oscillations in the wings of the peaks. For very large values of d, where the first-order Bragg peak approaches the edge of the mirror reflection, two general types of multilayers can be distinguished. In the first (typified in the present work by Ni/Ti), there is a large (30% or more) reduction in the actual value of the critical wave vector for total reflection while, in the second (typified here by Fe/Ge), there is very little reduction (3 % or so). The origin of these two very different types of behavior is explained. It is also shown that, within the dynamical theory of diffraction, the change in the position of the center of the Dar...

    outcome six months after discharge was significantly worse in patients with early epileptiform discharges (p=0.01). Epileptiform discharges within the first 30 min of EEG recording are predictive for the occurrence of ictal EEG patterns and for RPPIIU on subsequent cEEG, for acute convulsive seizures during the ICU stay, and for a worse functional outcome after 6 months of follow-up.

    SWAN, the Solar Wind ANisotropies all-sky hydrogen Lyα camera on the Solar and Heliospheric Observatory spacecraft that makes all-sky images of interplanetary neutral hydrogen, has an ongoing campaign to make special observations of comets, both short- and long-period ones, in addition to the serendipitous observations of comets as part of the all-sky monitoring program. We report here on a study of several short-period comets that were detected by SWAN: 21P/Giacobini-Zinner (1998 and 2005 apparitions), 19P/Borrelly (2001 apparition), 81P/Wild 2 (1997 apparition), and 103P/Hartley 2 (1997 apparition). SWAN observes comets over long continuous stretches of their visible apparitions and therefore provides excellent temporal coverage of the water production. For some of the observations we are also able to analyze an entire sequence of images over many days to several weeks/months using our time-resolved model and extract daily average water production rates over continuous periods of several days to months. The short-term (outburst) and long-term behavior can be correlated with other observations. The overall long-term variation is examined in light of seasonal effects seen in the pre- to post-perihelion differences. For 21P/Giacobini-Zinner and 81P/Wild 2 the activity variations over each apparition were more continuously monitored but nonetheless consistent with previous observations. For 19P/Borrelly we found a very steep variation of water production rates, again consistent with some previous observations, and a variation over six months around perihelion that was reasonably consistent with the spin-axis model of Schleicher et al. and the illumination of the main active areas. During the 1997-1998 apparition of 103P/Hartley 2, the target comet of the EPOXI mission (the Deep Impact extended mission), we found a variation with heliocentric distance (∼r -3.6 ) that was almost as steep as 19P/Borrelly and, given the small measured radius near aphelion, this places

    Full text: The discovery of the quasi-crystals [D. Schechtman et. Al., Phys.] Rev. Lett. [53, 1951-1953 (1984)] made very narrow definition of the crystalline state based on the periodicity of a local arrangement of atoms. Since the definition of this State has been a matter of much controversy [G.R. Desiraju, Nature 423, 485 (2003); S. van Smaalen, IUCR Aperiodic Commission Reports. August 7, 2002; International Union of Crystallography. Report of the Executive Committee for 1991; ACTA Cryst. A48, 922-946 (1992)]. We will make a presentation of the current time of the crystallography in this regard from the conceptual point of view. We show the use of the formalism of algorithmic complexity or Kolmogorov [M. Li and P. Vitanyi, An Introduction to Kolmogorov Complexity and Its Applications (Springer Verlag, Heidelberg, 1993), W.H. Zurek, Phys.] Rev. 40, 4731 (1989); Nature 341, 119-124 (1989)] provides a different perspective on the nature of the Crystallographic order. Infinite crystals can be considered solid with zero algorithmic complexities by atom. Show statistical analysis of inorganic compounds [J.L.C. Daams et al., Atlas of Crystal Structure Types for Intermetallic Phases (ASM International, Ohio, 1991), Fachinformationszentrum/NIST Inorganic Crystal Structure Database, Karlsruhe (2003) icsd.fkf.mpg.de] demonstrating that the minimization of complexity is a trend in the crystalline arrangement. We will then compare the degree of disorder of some typical solids according to their algorithmic complexity. Finally, space diffraction will be studied from this same perspective and will be discussed that zero algorithmic complexities by point in space of diffraction does not necessarily imply the same thing for the Atomic arrangement. The discrete portion of the diffraction pattern is a fingerprint of the underlying order but not the actual existence of long-range order. Experimental results will be showcased [E. Estévez-Rams et al., Physical Review B, 63 (2001

    We study the resonant response of a nonlinear system to external periodic perturbations. We show by numerical simulation that the periodic resonance curve may anticipate the dynamical instability of the unperturbed nonlinear periodic system, at parameter values far away from the bifurcation points. In the presence of noise, the buried intrinsic periodic dynamics can be picked out by analyzing the system's response to periodic modulation of appropriate intensity

    A method is described to solve the Poisson problem for a three dimensional source distribution that is periodic into one direction. Perpendicular to the direction of periodicity a free space (or open) boundary is realized. In beam physics, this approach allows to calculate the space charge field of a continualized charged particle distribution with periodic pattern. The method is based on a particle mesh approach with equidistant grid and fast convolution with a Green's function. The periodic approach uses only one period of the source distribution, but a periodic extension of the Green's function. The approach is numerically efficient and allows the investigation of periodic- and pseudo-periodic structures with period lengths that are small compared to the source dimensions, for instance of laser modulated beams or of the evolution of micro bunch structures. Applications for laser modulated beams are given.

    We numerically find many unstable periodic solutions embedded in a chaotic attractor in a macroeconomic growth cycle model of two countries with different fiscal policies, and we focus on a special type of the unstable periodic solutions. It is confirmed that chaotic behavior represented by the model is qualitatively and quantitatively related to the unstable periodic solutions. We point out that the structure of a chaotic solution is dissolved into a class of finite unstable periodic solutions picked out among a large number of periodic solutions. In this context it is essential for the unstable periodic solutions to be embedded in the chaotic attractor
