Photochemical heat-shock response in common bean leaves as affected by previous water deficit

The heat sensitivity of photochemical processes was evaluated in the common bean (Phaseolus vulgaris) cultivars A222, A320, and Carioca grown under well-watered conditions during the entire plant cycle (control treatment) or subjected to a temporal moderate water deficit at the preflowering stage (PWD). The responses of chlorophyll fluorescence to temperature were evaluated in leaf discs excised from control and PWD plants seven days after the complete recovery of plant shoot hydration. Heat treatment was done in the dark (5 min) at the ambient CO2 concentration. Chlorophyll fluorescence was assessed under both dark and light conditions at 25, 35, and 45 degrees C. In the dark, a decline of the potential quantum efficiency of photosystem II (PSII) and an increase in minimum chlorophyll fluorescence were observed in all genotypes at 45 degrees C, but these responses were affected by PWD. In the light, the apparent electron transport rate and the effective quantum efficiency of PSII were reduced by heat stress (45 degrees C), but no change due to PWD was demonstrated. Interestingly, only the A222 cultivar subjected to PWD showed a significant increase in nonphotochemical fluorescence quenching at 45 degrees C. The common bean cultivars had different photochemical sensitivities to heat stress altered by a previous water deficit period. Increased thermal tolerance due to PWD was genotype-dependent and associated with an increase in potential quantum efficiency of PSII at high temperature. Under such conditions, the genotype responsive to PWD treatment enhanced its protective capacity against excessive light energy via increased nonphotochemical quenching.

O impacto do diagnóstico de demência no casal

RESUMO: A experiência de viver com demência ocorre, frequentemente, num contexto de uma relação conjugal duradoura. A qualidade da relação e o sentido de coerência (conjunto de características pessoais que permite compreender, gerir e integrar os factores de stress de forma construtiva) apresentam-se como factores promotores e protectores da saúde, no contexto de experiências adversas, nomeadamente de doença. Provavelmente, o mesmo poderá acontecer nos quadros demenciais. O presente estudo teve como objectivo principal analisar o impacto do diagnóstico, no contexto das fases iniciais de demência, em casais de pessoas idosas, explorando o papel da qualidade da relação conjugal e do sentido de coerência na confrontação com o diagnóstico e na experiência de viver com a doença. Realizámos um estudo observacional de seis casais de pessoas idosas (pessoas com demência e respectivos cônjuges prestadores de cuidados), com recurso a entrevistas individuais e conjuntas como suplemento metodológico central, suportado pela utilização dos instrumentos: Orientation to Life Questionnaire - SOC (Antonovsky, 1987) e Quality of Carer-Patient Relationships – QCPR (Spruytte et al. 2000). Os resultados sugerem que a qualidade da relação e um sentido de coerência mais elevado podem facilitar uma adaptação bem-sucedida aos desafios, promover a adopção de estratégias para reforçar os aspectos positivos da experiência de cuidar e atenuar os negativos (sobrecarga e sofrimento psíquico do cuidador), encorajar padrões positivos no acesso e na utilização dos cuidados formais e adiar a institucionalização precoce da pessoa com demência.----------------------- ABSTRACT: In couples, caregiving experiences in dementia usually occur within long-standing relationships preceding the onset of the illness and evolving as it progresses. The quality of relationship (QR) and Antonovsky’s salutogenic construct of sense of coherence (SOC) are assumed to promote and protect health in stressful situations, such as dementia. SOC refers to the extent to which a person considers his/her life as comprehensible, manageable and meaningful. We aim to uncover the role of QR and SOC as moderator or mediator in the ability of patients and their partners to cope with the impact of dementia We studied six couples in which one spouse had been diagnosed with dementia. We used a qualitative research approach (combining in-depth individual and joint interviews), triangulated with the measures Orientation to Life Questionnaire - SOC scale (Antonovsky, 1987) and the Quality of Carer-Patient Relationships – QCPR (Spruytte et al. 2000). The method was informed by a literature review on the role of RQ and SOC within dementia. Results highlight the importance of listening to both spouses, in a dyadic perspective, while acknowledging the voice of PwD themselves despite methodological challenges. Aspects of prior relationship impact on caregiving dynamics and on how the care-giver and care-recipient roles are experienced. At the same time, the experience of living with dementia impacts on the relationship, often causing change or loss which is difficult to accept or adjust to. Diagnosis played an important role on the SOC’s comprehensibility component (life makes sense). Good pre-caregiving and current relationship was associated with carers’ ability to cope, namely on SOC’s manageability (problems will be bearable) and meaningfulness (life is viewed as a challenge). Our findings suggest that an understanding of QR and SOC prior to diagnosis may encourage positive patterns of care, foster successful adaptation to changing needs, and support in-home arrangements as long as possible.

Persistence of ultrasound synovitis in patients with rheumatoid arthritis fulfilling the DAS28 and/or the new ACR/EULAR RA remission definitions: results of an observational cohort study.

OBJECTIVE: The primary aim of the study was to evaluate whether rheumatoid arthritis (RA) patients considered to be in remission according to clinical criteria sets still had persisting ultrasound (US) synovitis. We further intended to evaluate the capacity of our US score to discriminate between the patients with a clinically active disease versus those in remission. METHODS: This is an observational study nested within the Swiss Clinical Quality Management in Rheumatic Diseases (SCQM) rheumatoid arthritis cohort. A validated US score (SONAR score) based on a semi-quantitative B-mode and Doppler (PwD) score as part of the regular clinical workup by rheumatologists in different clinical settings was used. To define clinically relevant synovitis, the same score was applied to 38 healthy controls and the 90st percentile was used as cut-off for 'relevant' synovitis. RESULTS: Three hundred and seven patients had at least one US examination and concomitant clinical information on disease activity. More than a third of patients in both DAS28 and ACR/EULAR remission showed significant gray scale synovitis (P=0.01 and 0.0002, respectively) and PwD activity (P=0.005 and 0.0005, respectively) when compared to controls. The capacity of US to discriminate between the two clinical remission groups and patients with active disease was only moderate. CONCLUSION: This observational study confirms that many patients considered to be in clinical remission according the DAS and the ACR/EULAR definitions still have residual synovitis on US. The prognostic significance of US synovitis and the exact place of US in patients reaching clinical remission need to be further evaluated.

Disability in Iowa: Public Health Needs Assessment

According to the Centers for Disease Control and Prevention (CDC), the number of adults reporting a disability is expected to increase, along with the need for appropriate medical and public health services. People with disabilities (PWD) face many barriers to good heath, including having overall poorer health, less access toadequate health care, limited access to health insurance, skipping mediacl care because of cost, and engaging in risky health behaviors including smoking and physical inactivity. The goals of the Iowa public health needs assessment were to assess the burden of disability in Iowa counties including health risk factors such as chronic conditions, determine access to preventive health care, and determine the effect of socioeconomic conditions. The state level assessment was based on th 2009-2012 American Community Survey (ACS) and publiccally available Behavioral Risk FactorSurveillance System (BRFSS) 2011 survey. The 2001-2010 combined BRFSS data was used for county level assessment. The needs assessment led us to conclude that adult Iowans with idsabilities face several challenges compared to non-disabled adults. They are more likely to suffer from debilitating chronic conditions and social disparities. Counties with the higher levels of poverty were more likely to have PWD with higher levels of disability related disparities.

Ultrasound evaluation of synovitis in RA: Correlation with clinical disease activity and sensitivity to change in an observational cohort study.

OBJECTIVE: To evaluate the correlation between clinical measures of disease activity and a ultrasound (US) scoring system for synovitis applied by many different ultrasonographers in a daily routine care setting within the Swiss registry for RA (SCQM) and further to determine the sensitivity to change of this US Score. METHODS: One hundred and eight Swiss rheumatologists were trained in performing the Swiss Sonography in Arthritis and Rheumatism (SONAR) score. US B-mode and Power Doppler (PwD) scores were correlated with DAS28 and compared between the clinical categories in a cross-sectional cohort of patients. In patients with a second US (longitudinal cohort), we investigated if change in US score correlated with change in DAS and evaluated the responsiveness of both methods. RESULTS: In the cross-sectional cohort with 536 patients, correlation between the B-mode score and DAS28 was significant but modest (Pearson coefficient r=0.41, P<0.0001). The same was true for the PwD score (r=0.41, P<0.0001). In the longitudinal cohort with 183 patients we also found a significant correlation between change in B-mode and in PwD score with change in DAS28 (r=0.54, P<0.0001 and r=0.46, P<0.0001, respectively). Both methods of evaluation (DAS and US) showed similar responsiveness according to standardized response mean (SRM). CONCLUSIONS: The SONAR Score is practicable and was applied by many rheumatologists in daily routine care after initial training. It demonstrates significant correlations with the degree of as well as change in disease activity as measured by DAS. On the level of the individual, the US score shows many discrepancies and overlapping results exist.

Moderators of the Relationship between Family Caregiver Proxy-Ratings and Person with Dementia Self-Ratings of Quality of Life

As the dementia spectrum lacks any viable cure, quality of life is typically regarded as an essential measure of assessing the clinical course and evaluating interventions. With caregivers typically providing this rating to health professionals, the literature has noted inconsistencies between caregiver and person with dementia (PwD) ratings of quality of life and suggested several factors may moderate the rating relationship. To investigate this, an intraclass correlation coefficient was calculated to observe rating agreement and moderator regression analysis was conducted to explore potential moderators. Potential moderators of caregiver burden, caregiver age, caregiver income, PwD IADLs/ADLs, PwD education, PwD cognitive impairment, PwD depressive symptom severity, PwD behavioural symptom severity, as well as relationship between caregiver and PwD. Utilizing secondary data from 107 recruited dyads, analyses conducted found fair agreement between caregivers and those with dementia while none of the hypothesized factors were found to moderate the rating relationship.

Détermination des effets de l'administration des probiotiques sur l'attachement d'Escherichia Coli Entérotoxinogène F4 et l'expression de cytokines chez le porcelet sevré

Les diarrhées post-sevrages causées par des infections à Escherichia coli entérotoxinogène positif pour le fimbriae F4 (ETEC F4), entraînent des pertes économiques importantes chez les producteurs de porc. Depuis quelques années, l’utilisation de probiotiques, comme additif alimentaire pour prévenir ce type d’infection entérique et réduire les traitements aux antimicrobiens, suscite un intérêt grandissant en production porcine. Le but du présent travail est de déterminer l’influence de l’administration des probiotiques Pediococcus acidilactici (PA) et Saccharomyces cerevisiae boulardii (SCB) sur la colonisation et l’attachement des ETEC F4, l’accumulation de fluide intestinal et l’expression de cytokines dans l’iléon de porcelets sevrés. Dès la naissance, différentes portées de porcelets ont été affectées aux traitements suivants : PA, SCB, PA + SCB, témoin et témoin avec antibiotiques (ATB). Une dose quotidienne de probiotiques (1 × 109 UFC) a été administrée aux porcelets des groupes probiotiques durant la lactation et après le sevrage. Sept jours après le sevrage, à 28 jours d’âge, des porcelets positifs pour le récepteur intestinal spécifique pour F4 ont été infectés oralement avec une souche ETEC F4. Les porcelets ont été euthanasiés 24 heures après l’infection (jour 29) et différents échantillons intestinaux ont été prélevés. Chez les porcelets recevant des probiotiques, l’attachement des ETEC F4 à la muqueuse iléale était significativement diminué chez les groupes PA ou SCB en comparaison avec le groupe ATB. Finalement, l’expression de cytokines intestinales était plus élevée chez les porcs du groupe PA + SCB en comparaison avec les porcelets témoins. En conclusion, les résultats de cette étude suggèrent que l’administration de probiotiques pourrait être une alternative pour limiter les infections à ETEC F4 chez le porc.

Gastric stability and oral bioavailability of colistin sulfate in pigs challenged or not with Escherichia coli O149: F4 (K88)

The aim of the present study was to investigate the in vitro gastric stability of colistin sulfate (CS) and its antimicrobial activity against Escherichia coli and to study the impact of ETEC O149: F4 (K88) infection in pigs on CS intestinal absorption. The stability profile of CS was evaluated in a simulated gastric fluid (SGF). Antimicrobial activity of CS and its degradation products were examined in a 96-well polystyrene microplate model. The effect of experimental infection with ETEC O149: F4 on CS intestinal absorption was determined by quantification of CS systemic concentration using a validated LC–MS/MS method. A rapid degradation of CS accompanied by an increase in CS antimicrobial activity by comparison with non-degraded CS (P < 0.0001) was observed in SGF. Additionally, CS levels were not quantifiable in systemic circulation using a highly sensitive method and concurrent oral challenge did not affect CS absorption in an induction model of subclinical post-weaning diarrhea (PWD).

A critical study of major construction projects in kerala vis-a-vis effectiveness in project implementation

Chapter 1 presents a brief note on the state at which the construction industry stands at present, bringing into focus the significance of the critical study. Relevance of the study, area of investigation and objectives of the study are outlined in this chapter. The 2nd chapter presents a review of the literature on the relevant areas. In the third chapter an analysis on time and cost overrun in construction highlighting the major factors responsible for it has been done. A couple of case studies to estimate loss to the nation on account of delay in construction have been presented in the chapter. The need for an appropriate estimate and a competent contractor has been emphasised for improving effectiveness in the project implementation. Certain useful equations and thoughts have been formulated on this area in this chapter that can be followed in State PWD and other Govt. organisations. Case studies on project implementation of major projects undertaken by Government sponsored/supported organizations in Kerala have been dealt with in Chapter 4. A detailed description of the project of Kerala Legislature Complex with a critical analysis has been given in this chapter. A detailed account of the investigations carried out on the construction of International Stadium, a sports project of Greater Cochin Development Authority is included here. The project details of Cochin International Airport at Nedumbassery, its promoters and contractors are also discussed in Chapter 4. Various aspects of implementation which led the above projects successful have been discussed in chapter 5. The data collected were analysed through discussion and perceptions to arrive at certain conclusions. The emergence of front-loaded contract and its impact on economics of the project execution are dealt with in this chapter. Analysis of delays in respect of the various project narrated in chapter 3 has been done here. The root causes of the project time and overrun and its remedial measures are also enlisted in this chapter. Study of cost and time overrun of any construction project IS a part of construction management. Under the present environment of heavy investment on construction activities in India, the consequences of mismanagement many a time lead to excessive expenditure which are not be avoidable. Cost consciousness, therefore has to be keener than ever before. Optimization in investment can be achieved by improved dynamism in construction management. The successful completion of coristruction projects within the specified programme, optimizing three major attributes of the process - quality, schedule and costs - has become the most valuable and challenging task for the engineer - managers to perform. So, the various aspects of construction management such as cost control, schedule control, quality assurance, management techniques etc. have also been discussed in this fifth chapter. Chapter 6 summarises the conclusions drawn from the above criticalr1 of rhajor construction projects in Kerala.

Evaluation of communication behavior in persons with dementia during caregivers’ singing

The number of persons with dementia (PWD) is increasing rapidly worldwide. Cognitive impairments and communication difficulties are common among PWD. Therefore, gaining mutual togetherness in caring relation between PWD and their caregivers is important. This study was to investigate the effects of music therapeutic care (MTC) during morning care situations on improving verbal and nonverbal communication behaviors in people with dementia. An observation study with 10 PWD participating. Videotaped interactions (VIO) between PWD and their caregivers were conducted during eight weekly sessions, four recordings consisted of usual morning care and four recordings were of morning care with MTC intervention. The Verbal and Nonverbal Interaction Scale was used to analyze the recorded interactions at a later time. The unsociable verbal variable Cursing decreased significantly (P=.037) during MTC when compared with the baseline measurement. A significant (P=.000) reduction was observed for the unsociable nonverbal variable Does not respond to question. MTC significantly (P=.01) increased the mean score for the sociable nonverbal variable – Calm – relaxed. For sociable verbal communication, significant differences were observed for the variables Use coherent communication (P=.012), Use relevant communication (P=.009), Responds to questions (P=.000), Humming (P=.004), Singing (P=.000). MTC during morning care situations can be an effective non-pharmacological treatment, as well as nursing intervention in order to improve sociable communication behaviors, as well as reduce unsociable communication behaviors of PWDs

Gestão do trabalho das pessoas com deficiência no campo da saúde pública

Em virtude da reserva de vagas prevista em legislação, a presença de pessoas com deficiência - PcDs é cada vez mais frequente nas organizações públicas. Percebe-se que nem sempre essas organizações estão preparadas, quer seja arquitetonicamente quer seja por uma cultura de inclusão, para receber e gerir essa força de trabalho. Diante desse contexto, o presente estudo procurou discutir as práticas de gestão das pessoas com deficiência na área pública, a partir do enfoque da inclusão, utilizando o caso do Instituto Nacional de Câncer José Alencar Gomes da Silva - INCA. Para a construção do estudo foi realizada uma pesquisa qualitativa com análise documental e com entrevistas semiestruturadas. No intuito de abarcar a visão dos diferentes grupos de pessoas que estão diretamente envolvidos com a temática no INCA foram entrevistados três tipos de profissionais, a saber: servidores com deficiência, chefias diretamente ligadas a essas PcDs e chefia da área de gestão de pessoas. Constata-se uma preocupação do instituto em cumprir a determinação legal de ocupação das cotas reservadas no quadro de pessoal para as PcDs, porém ainda não foram desenvolvidos ou adaptados instrumentos institucionais de gestão que permitam a inclusão efetiva desses profissionais. Verificou-se também que a adaptação do INCA às dimensões de acessibilidade - arquitetônica, comunicacional, metodológica, instrumental, programática e atitudinal – ainda é incipiente. Formalmente não há nenhum elemento que impeça a participação das PcDs nos subsistemas de gestão de pessoas do INCA, contudo nem sempre são criadas e institucionalizadas as ferramentas necessárias à autonomia e à plena participação desses profissionais.

An intelligent system to detect drilling problems through drilled cuttings return analysis

Cuttings return analysis is an important tool to detect and prevent problems during the petroleum well drilling process. Several measurements and tools have been developed for drilling problems detection, including mud logging, PWD and downhole torque information. Cuttings flow meters were developed in the past to provide information regarding cuttings return at the shale shakers. Their use, however, significantly impact the operation including rig space issues, interferences in geological analysis besides, additional personel required. This article proposes a non intrusive system to analyze the cuttings concentration at the shale shakers, which can indicate problems during drilling process, such as landslide, the collapse of the well borehole walls. Cuttings images are acquired by a high definition camera installed above the shakers and sent to a computer coupled with a data analysis system which aims the quantification and closure of a cuttings material balance in the well surface system domain. No additional people at the rigsite are required to operate the system. Modern Artificial intelligence techniques are used for pattern recognition and data analysis. Techniques include the Optimum-Path Forest (OPF), Artificial Neural Network using Multilayer Perceptrons (ANN-MLP), Support Vector Machines (SVM) and a Bayesian Classifier (BC). Field test results conducted on offshore floating vessels are presented. Results show the robustness of the proposed system, which can be also integrated with other data to improve the efficiency of drilling problems detection.
