    Perceived air quality, Sick Building Syndrome (SBS) symptoms and productivity were studied in a normally furnished office space (108 m3) ventilated with an outdoor airflow of 3, 10 or 30 L/s per person, corresponding to an air change rate of 0.6, 2 or 6 h-1. The temperature of 22 degrees C, the relative humidity of 40% and all other environmental parameters remained unchanged. Five groups of six female subjects were each exposed to the three ventilation rates, one group and one ventilation rate at a time. Each exposure lasted 4.6 h and took place in the afternoon. Subjects were unaware of the intervention and remained thermally neutral by adjusting their clothing. They assessed perceived air quality and SBS symptoms at intervals, and performed simulated normal office work. Increasing ventilation decreased the percentage of subjects dissatisfied with the air quality (P < 0.002) and the intensity of odour (P < 0.02), and increased the perceived freshness of air (P < 0.05). It also decreased the sensation of dryness of mouth and throat (P < 0.0006), eased difficulty in thinking clearly (P < 0.001) and made subjects feel generally better (P < 0.0001). The performance of four simulated office tasks improved monotonically with increasing ventilation rates, and the effect reached formal significance in the case of text-typing (P < 0.03). For each two-fold increase in ventilation rate, performance improved on average by 1.7%. This study shows the benefits for health, comfort and productivity of ventilation at rates well above the minimum levels prescribed in existing standards and guidelines. It confirms the results of a previous study in the same office when the indoor air quality was improved by decreasing the pollution load while the ventilation remained unchanged. PMID:11089327

    This paper provides a review and synthesis of current knowledge about the associations of ventilation system types in office buildings with sick building syndrome symptoms and discusses potential explanations for the associations. Relative to natural ventilation, air conditioning, with or without humidification, was consistently associated with a statistically significant increase in the prevalence of one or more SBS symptoms. Prevalences were typically higher by approximately 30% to 200% in the air conditioned buildings. In two of three assessments from a single study, symptom prevalences were also significantly higher in air conditioned buildings than in buildings with simple mechanical ventilation and no humidification. In approximately half of assessments, SBS symptom prevalences were significantly higher in buildings with simple mechanical ventilation than in buildings with natural ventilation. Insufficient information was available for conclusions about the potential increased risk of SBS symptoms with humidification. The statistically significant associations of mechanical ventilation and air conditioning with SBS symptoms are much more frequent than expected from chance and also not likely to be a consequence of confounding by several potential personal, job, or building related confounders. The reasons for the increases in symptom prevalences with mechanical ventilation and particularly with air conditioning remain unclear. Multiple deficiencies in HVAC system design, construction, operation, or maintenance, including some which cause pollutant emissions from HVAC systems, may contribute to the increases in symptom prevalences.

    OBJECTIVES--Sick building syndrome (SBS) involves symptoms such as irritation to the eyes, skin, and upper airways, headache, and fatigue. The relations between such symptoms and both personal and environmental factors were studied in 225 female hospital workers, working in eight hospital units in the south of Sweden. METHODS--Symptoms of SBS and personal factors were measured by means of a standardised self administered questionnaire. The technical investigation comprised a building survey and measurements of room temperature, supply air temperature, air humidity, and exhaust air flow. RESULTS--The prevalence of symptoms differed from one unit to another. The mean value of weekly complaints of fatigue was 30%, of eye irritation 23%, and of dry facial skin 34%. Eye irritation was related to work stress, self reported exposure to static electricity, and was also more common in buildings with a high ventilation flow and a high noise level (55 dB(A)) from the ventilation system. Nasal symptoms were related to asthma and hay fever only. Throat symptoms were more common in smokers, subjects with asthma or hay fever, new buildings, and in buildings with a high ventilation flow. Facial skin irritation was related to a lack of control of the work conditions, and was more common in new buildings, and buildings with a high ventilation flow and ventilation noise. General symptoms, such as headache and fatigue, were related to current smoking, asthma or hay fever, work dissatisfaction, and static electricity. CONCLUSION--As the prevalence of symptoms was high, there is a need to improve the indoor environment as well as the psychosocial environment in hospitals. These improvements could include a reduction of ventilation noise, minimised smoking, and improvements in the psychosocial climate. Further research is needed to identify indoor climatic factors that cause the increased prevalence of symptoms of SBS in new buildings. PMID:7735389

    The results of the numerical simulation of the laser beam quality changes after propagation through the passive and active optical systems with the linear and nonlinear aberrations are presented. The new algorithm for the calculation of the phase conjugation by steady-state SBS is developed. It is found that the parameter M2 of the Stokes beam in the saturation regime is often nearly the same as that of the pump beam. The generation of short (approximately 1.5 nsec) pulses with energies exceeding 4 mJ has been obtained using passive Q-switching of the short (approximately 10 cm) resonator of Nd:YAG laser by GSGG:Cr,Nd crystals. After SBS-compression the pulses with approximately 120 psec duration and with energies of approximately 1 mJ have been obtained. Four-pass Nd:YAG amplifier amplifies the pulses to the energies approximately 500 mJ with the duration of pulses of approximately 170 psec. Experimentally obtained results are in good agreement with the mathematical modelling of short pulse generation and amplification.

    AN INCREASINGLY COMMON ENVIRONMENTAL HEALTH PROBLEM: Complaints related to indoor environment represent one of the most frequent problems that environmental health practitioners are confronted with. Hence the incidence of the Sick Building Syndrome (SBS) has been increasing since the Seventies. DIFFERING DEFINITIONS AND CLINICAL PRESENTATIONS: The WHO defines SBS as an excess of complaints and symptoms occurring in certain occupants of non-industrial buildings. The syndrome can only be evoked after elimination in the person concerned of a disease related to the building, the aetiological agent of which is identifiable. The symptoms described during SBS (headaches, concentration problems, asthenia, irritation of the skin or nasal mucosa, of the eyes and upper respiratory tract.) are non specific and frequently observed in the general population. AN UNKNOWN CASE, BUT NUMEROUS AETIOLOGICAL FACTORS SUSPECTED: There is no unanimously accepted definition nor physio-pathological theory to explain the occurrence of SBS in a particular building. Many favouring factors, including the type and rate of ventilation, volatile organic compounds, particles and humidity have been suspected. TECHNICAL, SOCIAL, AND MEDICAL MANAGEMENT IS REQUIRED: Although the symptoms are benign, they can be uncomfortable or even handicapping and prevent the functioning of workplaces. The SBS, the social and economical costs of which are high, requires multidisciplinary management. PMID:14576597

    Phase conjugation of laser radiation is studied by SBS in a capillary filled with TiCl{sub 4}. A combination of a relatively low SBS threshold for spatially inhomogeneous radiation, a high quality of phase conjugation, and a wide dynamic range of the phase conjugated radiation energy was obtained. PBr{sub 3} is proposed and investigated as a nonlinear optical medium for further decreasing the SBS threshold. (nonlinear optical phenomena)

    A survey and critical review were undertaken of existing published literature and reports on indoor air quality (IAQ), ventilation, and IAQ- and building-related health problems in schools, including California schools. Over 450 relevant publications were obtained and reviewed, including papers published in the archival peer-reviewed scientific literature, proceedings of scientific meetings, government reports, 77 NIOSH Health Hazard Evaluation Reports (HHER) and 70 reports on investigations of problem schools in California. Most of the reviewed literature was for complaint or problem schools. The types of health symptoms reported in schools were very similar to those defined as sick building syndrome (SBS) symptoms, although this may be due, at least in part, to the type of health symptom questionnaires used. Some of the symptoms, e.g., wheezing, are indicative of asthma. In the studies in which complaint and noncomplaint buildings or areas were compared, complaint buildings generally had higher rates of health symptoms.

  8. Quantitative relationship of sick building syndrome symptoms with ventilation rates

    Data from published studies were combined and analyzed to develop best-fit equations and curves quantifying the change in sick building syndrome (SBS) symptom prevalence in office workers with ventilation rate. For each study, slopes were calculated, representing the fractional change in SBS symptom prevalence per unit change in ventilation rate per person. Values of ventilation rate, associated with each value of slope, were also calculated. Linear regression equations were fitted to the resulting data points, after weighting by study size. Integration of the slope-ventilation rate equations yielded curves of relative SBS symptom prevalence versus ventilation rate. Based on these analyses, as the ventilation rate drops from 10 to 5 L/s-person, relative SBS symptom prevalence increases approximately 23percent (12percent to 32percent), and as ventilation rate increases from 10 to 25 L/s-person, relative prevalence decreases approximately 29percent (15percent to 42percent). Variations in SBS symptom types, building features, and outdoor air quality may cause the relationship ofSBS symptom prevalence with ventilation rate in specific situations to differ from the average relationship predicted in this paper.

    Thirty spectroscopic binary stars were found in the Second Byurakan Survey (SBS). They show composite spectra - WD(DA)+dM or dC (for example Liebert et al. 1994). They may have red color, if the radiation of the red star dominates, and blue one, if the blue star is brighter and have peculiar spectrum in our survey plate. We obtained slit spectra for most of such objects. But we often see the spectrum of one component, because our slit spectra did not cover all optical range. We examine by eye the slit spectra of all SBS stellar objects (˜700) in SDSS DR7, DR8 or DR9 independent on our observations. We confirmed or discovered the duplicity of 30 stars. Usually they are spectroscopic binaries, where one component is WD (DA) and the second one is a red star with or without emission. There also are other components combinations. Sometimes there are emission lines, probably, indicating variable ones.

    Background: Menopausal symptoms and sleep difficulty were physiological processes that were affected by genetic and other factors. This study was to investigate the prevalence of menopausal symptoms and sleep quality in menopausal transition (MT) and postmenopause (PM) women in Taiyuan, Shanxi. Methods: A community-based survey of women's menopausal symptoms and sleep quality was conducted between July 2012 and May 2013 at six municipal districts of Taiyuan, Shanxi. A sample of 2429 women aged 40–59 years was divided into four groups: early MT, late MT, early PM, and late PM. Sleep quality in the past 2 weeks before the interview was recorded. The data were analyzed using SPSS 16.0. Results: The prevalence of menopausal symptoms was 49.8%. Mild, moderate, and severe symptoms were observed in 28.9%, 18.5%, and 2.5% of participants, respectively. The highest prevalence of menopausal symptoms occurred in the early postmenopausal stage; the subsequences were the late postmenopausal stage and the early MT stage. Interestingly, among the 13 items of modified Kupperman index, the five most common symptoms were fatigue, arthralgia and myalgia, decreased libido, insomnia, and nervousness. Meanwhile, 55% perimenopausal women had poor sleep. Conclusions: Menopausal symptoms are common but mild among women in Taiyuan, Shanxi during MT and PM. In these stages, the prevalence of poor sleep is high. PMID:26996470

    SBS characteristics of the KD{sup *}P crystals were determined by the method of SBS generation excitation in the transverse resonator. Fused silica was utilized as the test medium. Experimental oscillograms of Stokes pulses were processed by the method of pulse form approximation using the four-parametric function of time. The obtained SBS characteristics for these materials are in good agreement with the published literary data and the available theoretical presentation data.

    We report the three-dimensional simulation results of phase conjugation upon nonstationary stimulated Brillouin scattering of a focused laser beam. It is shown that in the case of deep focusing of laser radiation in the SBS cell, the phase conjugation quality decreases with increasing laser power and reflection coefficient, in agreement with experimental results. In calculations, the process of Stokes radiation generation is studied in detail, the reasons for a decrease in the phase conjugation quality are explained, and a means of its improvement is proposed.

    Using a daily diary method, this study examined concurrent and time-lagged relations between marital and parent-child relationship qualities, providing a test of the spillover and compensatory hypotheses. Additionally, this study tested both mothers’ and fathers’ depressive symptoms as moderators of these daily linkages. Participants were 203 families, in which mothers and fathers completed daily diaries for 15 days. At the end of each reporting day, parents independently rated the emotional quality of their relationship with their spouse and with their child that day. Controlling for global levels of marital satisfaction, marital conflict, and parenting, a positive association was found between mothers’ and fathers’ daily ratings of marital quality and their ratings of parent-child relationship quality, supporting the spillover hypothesis. When considering time-lagged relations, support was found for the compensatory hypothesis for mothers: lower levels of marital quality were related to increases in mother-child relationship quality from one day to the next. Further, both maternal and paternal depressive symptoms moderated the link between marital quality and the other parent’s relationship quality with their child. Whereas maternal depressive symptoms strengthened spillover relations for fathers on the next day, paternal depression was related to less spillover for mothers on the same day. Alternative models did not find evidence for parent-child relationship quality as a predictor of changes in marital quality on the next day. The findings underscore the importance of the quality of the marital relationship for predicting the quality of other family relationships. PMID:24821519

    Monitoring asthma in children in clinical practice is primarily performed by reviewing disease activity (daytime and night-time symptoms, use of reliever medication, exacerbations requiring frequent use of reliever medication and urgent visits to the healthcare professional) and the impact of the disease on children's daily activities, including sports and play, in a clinical interview. In such an interview, most task force members also discuss adherence to maintenance therapy and the patients' (and parents') views and beliefs on the goals of treatment and the amount of treatment required to achieve those goals. Composite asthma control and quality of life measures, although potentially useful in research, have limited value in clinical practice because they have a short recall window and do not cover the entire spectrum of asthma control. Telemonitoring of children with asthma cannot replace face-to-face follow-up and monitoring because there is no evidence that it is associated with improved health outcomes. PMID:26028631

    Various schemes for amplification of Stokes signals are investigated. Some new systems, such as an SBS amplifier in the transient amplification regime and a combined laser amplifier-SBS amplifier, are proposed and realised. Conditions are found under which amplification is accompanied by small distortions of the spatial structure of a signal. A two-pass system for small-signal amplification with phase conjugation is developed by using a PC mirror in the combined amplification system. The gains up to 10{sup 16} were obtained for the phase conjugation quality {approx}80%, the output energy {approx}1 J, and pulse duration {approx}30 ns. (nonlinear optical phenomena)

    The phase conjugation (PC) of a focused Gaussian laser beam with a partial spatial coherence of the wave front is studied numerically and theoretically upon SBS within the framework of a three-dimensional nonstationary SBS model, which takes into account transient processes and SBS saturation. The dependences of the PC coefficient h on the laser radiation power are obtained for different excesses of the angular divergence over the diffraction limit {xi}. It is found that for the given reflectance of laser radiation from the SBS mirror, the PC coefficient monotonically decreases with increasing the divergence. For example, under the near threshold SBS conditions, h decreases from 70% to 30%, when {xi} increases from 1 to 10. For the given divergence, the PC coefficient increases with increasing the reflectance and approaches the ideal one (h > 90%) upon deep SBS saturation, when the reflectance exceeds 90%-95%.

    We demonstrate a technique for SBS reduction in a nanosecond Yb-fiber amplifier by imposing 1.19 GHz/ns frequency chirp on the seed pulses with a pulse-driven phase modulator. A nearly 9-fold increase in the SBS threshold was observed for 8.4 ns pulses. SBS threshold data and transient SBS gain for various degrees of chirp are reported and compared with theoretical calculations. We further demonstrate the recovery of the input narrowband spectrum by applying an opposite chirp with a second phase modulator after the amplification. PMID:27410540

    This study investigated associations among third grade teachers’ (n = 27) symptoms of depression, quality of the classroom-learning environment (CLE), and students’ (n = 523, mean age 8.6 years) math and literacy performance. Teachers’ depressive symptoms in the winter negatively predicted students’ spring mathematics achievement. This depended on students’ fall mathematics scores; students who began the year with weaker math skills and were in classrooms where teachers reported more depressive symptoms achieved smaller gains than did peers whose teachers reported fewer symptoms. Teachers’ depressive symptoms were negatively associated with quality of CLE, and quality of CLE mediated the association between depressive symptoms and student achievement. Findings point to the importance of teachers’ mental health, with implications for policy and practice. PMID:25676719

    Few studies have examined the relationship between marital quality and adjustment to the impending loss of a terminally ill spouse. Most studies of marital quality and grief have been based on retrospective reports of the marriage rather than pre-loss assessments. Here, we tested the pre-loss cross-sectional effects of having a security-enhancing marriage on traumatic grief and depressive symptoms among 59 caregivers aged 50 and over of terminally ill spouses. We also examined whether insecure attachment styles were associated with traumatic grief and depressive symptoms. Findings suggest that security-increasing marriages and insecure attachment styles put spouses at risk for elevated traumatic grief symptoms. Results also indicate that marital quality and attachment style did not interact and that neither was significantly associated with depressive symptoms. The differences in the relationship of marital quality and attachment styles to the two outcomes suggest that the etiology of traumatic grief and depressive symptoms may be distinct. PMID:9741563

    Examining longitudinal data from the Toledo Adolescent Relationships Study (TARS) (n = 927), we assessed associations between physical victimization by an intimate partner, indicators of poor relationship quality, and depressive symptoms among young adult men and women in casually dating, exclusively dating, cohabiting, and marital relationships. In zero-order models, we found that physical victimization increased depressive symptoms. In multivariate models, victimization was a risk factor for depressive symptoms with the inclusion of prior depressive symptoms, family factors reflecting the intergenerational transmission of violence, sociodemographic background, and relationship characteristics including union status. Yet with the additional inclusion of indicators of poor relational quality, victimization was not a significant predictor of depressive symptoms. Arguing and poor communication influenced victimization and depressive symptoms. The associations between victimization and depressive symptoms did not differ by gender, nor were the effects of poor relationship quality on depressive symptoms conditional on gender. Thus, depressive symptoms are similarly responsive to intimate partner victimization, and for both women and men these associations were not significant with the inclusion of indicators of poor relationship quality. Findings underscored that victimization often occurs within relationship contexts characterized by a range of negative dynamics; thus multifaceted relationship-centered prevention and intervention efforts are likely to be more useful than those focusing only on negative messages about the use of aggression with an intimate partner.

    Our objective is to report on the prevalence of phonatory symptoms and impact on quality of life in a group of female patients with goiter who had not been selected for surgery or who had not presented to the emergency room with respiratory distress. A total of 40 patients with goiter and 14 controls were enrolled in this study. Demographic data included age, sex, laryngopharyngeal reflux disease, allergy, smoking, duration of disease, presence or absence of compressive symptoms, presence or absence of thyroid gland nodules, vascular status, presence or absence of calcifications, and thyroid-stimulating hormone levels. Phonatory symptoms included hoarseness, vocal fatigue, vocal straining, lump sensation, and aphonia. The Voice Handicap Index 10 was used to assess the impact of phonatory symptoms on quality of life. The most common phonatory symptom in the patients with goiter was vocal fatigue followed by lump sensation. The only phonatory symptom that was significantly more present in patients with goiter was vocal straining. As for the impact of phonatory symptoms on quality of life, 15.8% of goiter patients had a Voice Handicap Index score >7 compared with 7.7% of controls. Phonatory symptoms are common in patients with goiter, with vocal straining occurring significantly more frequently than in controls. In 1 of 6 patients, the presence of phonatory symptoms had an impact on quality of life. PMID:27434485

    Indoor environment is associated with the sick building syndrome (SBS), but little is known about the contribution of outdoor air pollution and meteorological conditions to SBS. We studied associations between outdoor air pollution, meteorological parameters and selected indoor exposure and building characteristics at home and weekly SBS symptoms in a standardized questionnaire study among 3485 randomly selected adults in China. Outdoor factors included particulate matters with diameter <10μm (PM10), sulfur dioxide (SO2), nitrogen dioxide (NO2), outdoor temperature (T), relative air humidity (RH), and wind speed (WS) during last three months. Multiple logistic regression was applied calculating odds ratios (OR) with 95% confidence interval (95% CI). Asthma or allergic rhinitis (atopy) was associated with all types of SBS symptoms except fatigue. Indoor factors played a major role in SBS symptoms. Mold/dampness on the floor/ceiling was associated with fatigue OR=1.60 (1.11-2.30) and headache OR=1.80 (1.07-3.04). Moldy odor was associated with fatigue OR=1.59 (1.07-2.37) and dermal symptoms OR=1.91 (1.21-3.02). Window pane condensation in winter was associated with fatigue OR=1.73 (1.30-2.31) and throat symptoms OR=1.53 (1.01-2.31). Damp bed clothing was related with throat symptom OR=1.62 (1.09-2.40). Home redecoration was associated with fatigue OR=1.49 (1.07-2.06). Frequent window opening was associated with less nose symptoms OR=0.54 (0.36-0.82) and mechanical ventilation in the bathroom reduced dermal symptoms OR=0.66 (0.44-0.99). Females were more susceptible to redecoration and window pane condensation than men. No associations with SBS were observed for outdoor air pollutants or meteorological parameters in the final models combining indoor and outdoor factors, although SO2, T, and RH were associated with some SBS symptoms (fatigue, eyes and nose symptoms) in the separate outdoor models. In conclusion, indoor mold/dampness, air pollution from redecoration

    Co-rumination, the tendency to dwell on negative events and feelings with a relationship partner, is an aspect of relationships that has been associated with socioemotional adjustment tradeoffs and is found to be associated with depressive symptoms. However, depending on the context in which it occurs, co-rumination is not necessarily associated with detriments to mental well-being. Differences in relationship quality within certain relationships may explain why co-rumination is not always associated with depressive symptoms. In the current study, we utilized self-report measures in an ethnically diverse sample (53.5 % non-White) of 307 first term college students (65 % female) in order to elucidate how co-rumination between roommates may be associated with depressive symptoms. We found that the association between co-rumination and depressive symptoms was moderated by relationship quality such that co-rumination in a high quality relationship was not associated with depressive symptoms whereas the opposite was true in low quality relationships. Moreover, we found moderated mediation, such that the variance in the association between co-rumination and depressive symptoms was explained via self-esteem, but only for those co-ruminating within a low quality relationship. These results suggest that relationship quality may impact the extent to which co-rumination is associated with depressive symptoms among first year college students. PMID:26649743

    The 6-m telescope was used in conjunction with a scanner (IPCS) and the SP-124 spectrograph to make an investigation with resolution approx. 3.5 A of three new quasars: SBS 0953 + 549 (z/sub e/ = 2.580), SBS 1116 + 603 (z/sub e/ = 2.628), and SBS 1138 + 584 (z/sub e/ = 1.699). The spectra of these quasars are analyzed. The emission line L/sub approx./ in the quasar SBS 1116 + 603 may have a two-component structure: a narrow peak (FWHM a 3000 km/sec) and a broad pedestal (FWHM a 19,400 km/sec). In the quasar SBS 0953 + 549, the profile of the emission line L/sub approx./ recalls the profiles of P Cyg type lines, which are observed in the spectra of stars with expanding shells; two strong (tau approx. 1) and broad (FWHM approx. 1700 and 1000 km/sec) absorption lines with z/sub a/ = 2.451 and 2.503 have been found and identified as L/sub approx./ lines. The symmetric profiles of these lines correspond to N(HI) approx. 10/sup 20/ cm/sup -2/ for the cloud with z/sub a/ = 2.541 and 5 x 10/sup 19/ cm/sup -2/ for the cloud with z/sub a/ = 2.503. The authors have also estimated the line-of-sight densities of heavy elements found at z/sub a/ = 0.3800 (SBS 0953 + 549) and z/sub a/ = 1.4082 (SBS 1138 + 584). The densities of the absorption details in these and other known quasars are compared.

    While the importance of assessing the occupational consequences of insomnia is emphasized in clinical nosologies and research guidelines, there is little consensus on which aspects of occupational performance should be assessed, the most methodologically justifiable measures of insomnia and work performance, and how outcomes should be reported. The present review was designed to summarize and methodologically critique the assessment of those aspects of occupational performance most impacted by (or most frequently associated with) insomnia symptoms. The 30 studies which met the review inclusion criteria broadly addressed six domains of occupational functioning: absenteeism; workplace accidents; productivity; punctuality; job satisfaction and career progression. Collectively, study outcomes support the conclusions that insomnia symptoms: are consistently associated with excess absenteeism; elevate accident risk in the workplace; reduce subjectively experienced workplace productivity (at least in the shorter term); inhibit career progression; and can degrade job satisfaction. Study outcomes do not support the conclusion that people with insomnia are significantly less punctual than other workers. The overall value of the occupational sleep-health literature, however, is limited by a lack of comparability among studies. In particular, there is a clear need to standardize definitions of sleep and occupational outcomes, and to recognize the confounding influence of health variables on occupational performance and sleep.

    Background Children with chronic conditions often experience numerous symptoms, but few research studies examine patterns of symptoms and quality of life (QoL) indicators. Objective To examine if reliable latent classes of children with chronic medical conditions can be identified based on the clustering of symptoms and QoL indicators. Methods Structured interviews were conducted with children ages 9 to 21 living with chronic medical conditions (N = 90). Multiple symptoms (e.g., pain, sleep, fatigue, and depression) and QoL indicators (e.g., life satisfaction and social support) were measured. Physical health and emotional, social, and school functioning were measured using the Pediatric Quality of Life Inventory (PedsQL). Latent class analysis was used to classify each child into a latent class whose members report similar patterns of responses. Results A three-class solution had the best model fit. Class 1 (high-symptom group; n = 15, 16.7%) reported the most problems with symptoms and the lowest scores on the QoL indicators. Class 2 (moderate-symptom group; n = 39, 43.3%) reported moderate levels of both symptoms and QoL indicators. Class 3 (low-symptom group; n = 36, 40.0%) reported the lowest levels of symptoms and the highest scores on the QoL indicators. Conclusions The three latent classes identified in this study were distributed along the severity continuum. All symptoms and QoL indicators appeared to move in the same direction (e.g. worse symptoms with lower QoL). The PedsQL psychosocial health summary score (combining emotional, social, and school functioning scores) discriminated well between children with different levels of disease burden. PMID:24411513

    The purpose of this cross-sectional study was to examine the relative contributions of negative symptomatology, insight, and coping to quality of life (QOL) in a sample of 92 consecutive outpatients with stable schizophrenia referring to the Department of Neuroscience, Psychiatric Section, University of Turin, Struttura Semplice di Coordinamento a Valenza Dipartimentale (SSCVD), Department of Mental Health ASL TO1, Molinette, Italy, in the period between July 2009 and July 2011. In order to assess the specific effect of negative symptoms on QOL and the possible mediating role of insight and coping, two mediation hypotheses were tested, using multiple regression analyses specified by Baron and Kenny (1986). Our findings suggest that (a) higher negative symptoms predict a worse Quality of Life Scale (QLS) intrapsychic foundations (IF) subscale score; (b) attribution of symptoms and coping-social diversion have a direct and positive association with QLS-IF; (c) patients high in negative symptoms are less likely to use attribution of symptoms and coping-social diversion; and (d) attribution of symptoms and coping-social diversion act as partial mediators in the negative symptoms-QOL relationship. The prediction model accounts for 45.3% of the variance of the QLS-IF subscale score in our sample. In conclusion, our results suggest that insight and coping-social diversion substantially contribute to QOL in patients with higher negative symptoms. These factors are potentially modifiable from specific therapeutic interventions, which can produce considerable improvements in the QOL of this population. PMID:25128248

    Purpose: To examine prospectively patient self-rated symptoms and quality of life (QOL) indicators in patients with brain metastases following whole brain radiotherapy (WBRT). Methods and Materials: Consecutive patients with brain metastases referred for WBRT were approached for this study. Patients were asked to rate their symptoms and QOL using the Spitzer Quality of Life Index questionnaire. Follow-up was at 1, 2, and 3 months following WBRT. Linear regression analysis was used to determine the change in symptom severity over time. Results: Between August 2005 to October 2007, 129 patients with brain metastases were enrolled. The majority of patients (88%) received 20 Gy in five fractions. Median age was 64 years, and median Karnofsky Performance Status at baseline was 70. The most commonly experienced symptoms at baseline were headaches, weakness, balance problems, and fatigue. Thirty-five percent of patients rated neurological functional (NF) status as 1, indicating moderate neurological symptoms and need for assistance. Forty-three percent of patients had stable or decreased fatigue, and 47% had a stable or improved NF status over time (p = 0.0040). Although certain QOL domains improved over time, all other QOL domains and symptom items did not change significantly following WBRT. Conclusion: WBRT may have contributed to symptom stabilization in our study. An alternative goal of WBRT may be the prevention of symptom progression and QOL deterioration. Further research is required to select the most appropriate group of patients with brain metastases who would benefit most from WBRT.

    A new technique for mitigating stimulated Brillouin scattering (SBS) effects in narrow-linewidth Yb-doped fiber amplifiers is demonstrated with a model that reduces to solving an 8×8 system of coupled nonlinear equations with the gain, SBS, and four-wave mixing (FMW) incorporated into the model. This technique uses two seed signals, or 'two-tones', with each tone reaching its SBS threshold almost independently and thus increasing the overall threshold for SBS in the fiber amplifier. The wavelength separation of these signals is also selected to avoid FWM, which in this case possesses the next lowest nonlinear effects threshold. This model predicts an output power increase of 86% (at SBS threshold with no signs of FWM) for a 'two-tone' amplifier with seed signals at 1064nm and 1068nm, compared to a conventional fiber amplifier with a single 1064nm seed. The model is also used to simulate an SBS-suppressing fiber amplifier to test the regime where FWM is the limiting factor. In this case, an optimum wavelength separation of 3nm to 10nm prevents FWM from reaching threshold. The optimum ratio of the input power for the two seed signals in 'two-tone' amplification is also tested. Future experimental verification of this 'two-tone' technique is discussed.

    Background Psychiatric outpatients with a refugee background have often been exposed to a variety of potentially traumatizing events, with numerous negative consequences for their mental health and quality of life. However, some patients also report positive personal changes, posttraumatic growth, related to these potentially traumatic events. This study describes posttraumatic growth, posttraumatic stress symptoms, depressive symptoms, post-migration stressors, and their association with quality of life in an outpatient psychiatric population with a refugee background in Norway. Methods Fifty five psychiatric outpatients with a refugee background participated in a cross-sectional study using clinical interviews to measure psychopathology (SCID-PTSD, MINI), and four self-report instruments measuring posttraumatic growth, posttraumatic stress symptoms, depressive symptoms, and quality of life (PTGI-SF, IES-R, HSCL-25-depression scale, and WHOQOL-Bref) as well as measures of social integration, social network and employment status. Results All patients reported some degree of posttraumatic growth, while only 31% reported greater amounts of growth. Eighty percent of the patients had posttraumatic stress symptoms above the cut-off point, and 93% reported clinical levels of depressive symptoms. Quality of life in the four domains of the WHOQOL-Bref levels were low, well below the threshold for the’life satisfaction’ standard proposed by Cummins. A hierarchic regression model including depressive symptoms, posttraumatic stress symptoms, posttraumatic growth, and unemployment explained 56% of the total variance found in the psychological health domain of the WHOQOL-Bref scale. Posttraumatic growth made the strongest contribution to the model, greater than posttraumatic stress symptoms or depressive symptoms. Post-migration stressors like unemployment, weak social network and poor social integration were moderately negatively correlated with posttraumatic growth and

    The grafting of dimethyl amino ethyl methacrylate (DMAEMA) onto styrene-butadiene-styrene triblock copolymer (SBS) membrane was subsequently conducted by UV-radiation induced graft copolymerization without degassing to obtain the SBS-g-DMAEMA copolymer membrane. The substituted amino groups on the SBS-g-DMAEMA graft copolymer membrane were quaternized with iodomethane, and then the membrane was treated with heparin to prepare the heparin-containing SBS-g-DMAEMA copolymer membrane (SBS-g-DMAEMA-HEP). The graft copolymer membrane (SBS-g-DMAEMA) and the heparin-containing SBS-g-DMAEMA copolymer membrane (SBS-g-DMAEMA-HEP) were characterized by FTIR spectroscopy. The heparin content was determined by toluidine blue heparin assay. Contact angle, water content, and protein adsorption of fibrinogen and albumin experiments were also performed to evaluate the effect of graft amount and heparin content on the biocompatibility of SBS-g-DMAEMA and SBS-g-DMAEMA-HEP graft copolymer membranes. By using Kaelble's equation, the surface tension of SBS-g-DMAEMA and SBS-g-DMAEMA-HEP were determined. It was found that with increasing grafting amount and the heparin content, the surface tension and water content of SBS-g-DMAEMA membrane increased, whereas the contact angle decreased. The amount of the adsorption of albumin and fibrinogen decreased with increasing graft amount and heparin content. However, there was a minimum for adsorption of proteins in the SBS-g-DMAEMA and SBS-g-DMAEMA-HEP membranes. PMID:9429100

    The institutionalization of elders can decrease the health status and quality of life in this population. The aim of this study was to analyze the socio-demographic, quality of life, family support, and comorbidities variables in institutionalized elders with and without symptoms of depression. This was a cross-sectional study in institutions for long permanence for the elderly in the State of Rio Grande do Norte, Brazil. Two institutionalized elderly groups were compared (138 elders: 69 with and 69 without depressive symptoms). The instruments used were: mini-mental state examination, geriatric depression scale in the reduced version, socio-demographic questionnaire, quality of life (World Health Organization Quality of Life abbreviated-WHOQOL-bref), and inventory of perception of family support. Elders with depressive symptoms had inferior quality of life than those without depressive symptoms. Other factors that negatively influenced the quality of life in this population include: low economic conditions, occurrence of comorbidities, and deficient family assistance. These results have important implications in the decision making process with regard to strategies for improving the health status of institutionalized elders. PMID:26195233

    Objectives To identify symptom clusters among patients with advanced heart failure (HF) and the independent relationships with their quality of life (QoL). Methods This is the secondary data analysis of a cross-sectional study which interviewed 119 patients with advanced HF in the geriatric unit of a regional hospital in Hong Kong. The symptom profile and QoL were assessed by using the Edmonton Symptom Assessment Scale (ESAS) and the McGill QoL Questionnaire. Exploratory factor analysis was used to identify the symptom clusters. Hierarchical regression analysis was used to examine the independent relationships with their QoL, after adjusting the effects of age, gender, and comorbidities. Results The patients were at an advanced age (82.9 ± 6.5 years). Three distinct symptom clusters were identified: they were the distress cluster (including shortness of breath, anxiety, and depression), the decondition cluster (fatigue, drowsiness, nausea, and reduced appetite), and the discomfort cluster (pain, and sense of generalized discomfort). These three symptom clusters accounted for 63.25% of variance of the patients' symptom experience. The small to moderate correlations between these symptom clusters indicated that they were rather independent of one another. After adjusting the age, gender and comorbidities, the distress (β = −0.635, P < 0.001), the decondition (β = −0.148, P = 0.01), and the discomfort (β = −0.258, P < 0.001) symptom clusters independently predicted their QoL. Conclusions This study identified the distinctive symptom clusters among patients with advanced HF. The results shed light on the need to develop palliative care interventions for optimizing the symptom control for this life-limiting disease. PMID:27403150

    Parkinson's disease (PD) is a multisystem disorder, and besides the classical motor symptoms it is now known that patients also suffer from a variety of non-motor symptoms that adversely affect quality of life (QOL). Since data on Hispanic populations on this issue are scarce, our aim was to study the association of non-motor symptoms and QOL in patients with PD. This study is a cross-sectional observational study involving patients with PD using the following instruments: Quality of Life Questionnaire (PDQ-8), Unified Parkinson's Disease Rating Scale part III (UPDRS part III), and Non-Motor Symptom Scale (NMSS). We included 52 patients, with a median age of 64 years. Sleep/fatigue and mood/cognitive domains were the most common non-motor symptoms. Only sleep/fatigue, mood/cognition and gastrointestinal domains were associated with worse PDQ-8 scores. After adjusting for confounding variables, NMSS scores were significantly associated with a high PDQ-8 score. Higher NMSS scores were associated with and predicted higher PDQ-8 scores. The focus of management in PD should shift to a comprehensive strategy that incorporates care of non-motor symptoms and improves QOL. PMID:26424539

    To assess longitudinally the effect of living in the vicinity of coal-fired power stations on children with asthma, 99 schoolchildren with a history of wheezing in the previous 12 months were studied for 1 year, using daily diaries and measurements of air quality. The children had been identified in a cross-sectional survey of two coastal areas: Lake Munmorah (LM), within 5 km of two power stations, and Nelson Bay (NB), free from major industry. Daily air quality (sulphur dioxide (SO2) and nitrogen oxides (NOx)), respiratory symptoms, and treatment for asthma were recorded throughout the year. Measurements of SO2 and NOx at LM were well within recommended guidelines although they were several times higher than at NB: maximum daily levels in SO2 (micrograms/m3) were 26 at LM, 11 at NB (standard, 365); yearly average SO2 was 2 at LM, 0.3 at NB (standard, 60); yearly average NOx (micrograms/m3) was 2 at LM, 0.4 at NB (standard, 94). Marked weekly fluctuations occurred in the prevalence of cough, wheezing, and breathlessness, without any substantial differences between LM and NB. Overall, the prevalence of symptoms was low (10% for wheezing, 20% for any symptom). Whether the daily SO2 and NOx levels affected the occurrence of respiratory symptoms was investigated in children at LM using a logistic regression (Korn and Whittemore technique). For these children as a group, air quality measurements were not associated with the occurrence of symptoms.

    The present study examined the symptom cluster of fatigue, pain, and depression as a correlate of reduced quality of life (QOL) in individuals with multiple sclerosis (MS). The sample included 291 individuals with a definite diagnosis of MS who were enrolled in a 6-month longitudinal study of physical activity and QOL. The participants completed baseline measures of fatigue, depression, and pain and follow-up measures of QOL. Cluster analysis initially identified three sub-groups differing in experiences of fatigue, depression, and pain, and analysis of variance then indicated that the three sub-groups differed in QOL. The sub-group with lowest scores on all three symptoms had the highest QOL, whereas the sub-group with the highest scores on the symptoms had the worst QOL. Such findings provide preliminary support for fatigue, pain, and depression as a symptom cluster that correlates with reduced QOL in persons with MS. PMID:20804116

    There are fewer longitudinal studies from China on symptoms as described for the sick building syndrome (SBS). Here, we performed a two-year prospective study and investigated associations between environmental parameters such as room temperature, relative air humidity (RH), carbon dioxide (CO2), nitrogen dioxide (NO2), sulphur dioxide (SO2), ozone (O3), particulate matter (PM10), and health outcomes including prevalence, incidence and remission of SBS symptoms in junior high schools in Taiyuan, China. Totally 2134 pupils participated at baseline, and 1325 stayed in the same classrooms during the study period (2010–2012). The prevalence of mucosal symptoms, general symptoms and symptoms improved when away from school (school-related symptoms) was 22.7%, 20.4% and 39.2%, respectively, at baseline, and the prevalence increased during follow-up (P<0.001). At baseline, both indoor and outdoor SO2 were found positively associated with prevalence of school-related symptoms. Indoor O3 was shown to be positively associated with prevalence of skin symptoms. At follow-up, indoor PM10 was found to be positively associated with new onset of skin, mucosal and general symptoms. CO2 and RH were positively associated with new onset of mucosal, general and school-related symptoms. Outdoor SO2 was positively associated with new onset of skin symptoms, while outdoor NO2 was positively associated with new onset of skin, general and mucosal symptoms. Outdoor PM10 was found to be positively associated with new onset of skin, general and mucosal symptoms as well as school-related symptoms. In conclusion, symptoms as described for SBS were commonly found in school children in Taiyuan City, China, and increased during the two-year follow-up period. Environmental pollution, including PM10, SO2 and NO2, could increase the prevalence and incidence of SBS and decrease the remission rate. Moreover, parental asthma and allergy (heredity) and pollen or pet allergy (atopy) can be risk factors

    Dry eye disease (DED) is one of the most common reasons for patients (particularly those over the age of 50) to seek ophthalmic care. There is a wide array of causes for DED that can induce an alteration of the ocular surface system and determine the chronicity of the disease, including low blink rates (eg, computer use), systemic and topical drugs, autoimmune diseases, contact lens wear, and cataract and refractive surgery. Patients with dry eye experience numerous symptoms that can reduce their productivity and overall quality of life. This article presents the results of a roundtable focused on patients' symptoms. The goal was to better understand the symptoms reported by patients, the possible effects on visual function, the consequences on the quality of life, and the methodologies that can be used to measure and monitor symptoms in clinical practice and in clinical studies. The discrepancies between clinical signs and symptoms reported in some cases are considered in the context of the ocular surface system. PMID:27224876

    The process of assisted reproductive technology (ART), surrogacy and adoption pose different physical and psychological burdens on sub-fertile populations. Sub-fertile women (n = 176) were assessed retrospectively by questionnaire to determine if process (undergoing ART, surrogacy or adoption) or outcome (having a successful versus unsuccessful outcome) affected quality of life, coping style and psychological symptoms. The ART group was significantly younger, had a shorter period of sub-fertility, and was least likely to have a child than the adoptive and surrogate groups. Quality of life and psychological symptoms were not significantly different between groups, although significantly higher Mental Disengagement and Denial coping strategy scores were obtained for the ART group. Social, psychological, health and functioning quality of life, and Denial coping strategies were good predictors of outcome group. Treatment specific counselling of individuals use of coping strategies early on in their in/subfertility career to cope with the reality of prolonged childlessness is indicated. PMID:15911191

    Background Several reports on patients with chronic schizophrenia suggest that atypical versus typical antipsychotics are expected to lead to better quality of life (QOL) and cognitive function. Our aim was to examine the association of chronic treatment with typical or atypical antipsychotics with cognitive function, psychiatric symptoms, QOL, and drug-induced extrapyramidal symptoms in long-hospitalized patients with schizophrenia. Methodology and Principal Findings The Hasegawa Dementia Scale-Revised (HDS-R), Brief Psychiatric Rating Scale (BPRS), the Schizophrenia Quality of Life Scale, translated into Japanese (JSQLS), and the Drug-Induced Extrapyramidal Symptoms Scale (DIEPSS) were used to evaluate cognitive function, psychiatric symptoms, QOL, and drug-induced extrapyramidal symptoms. We examined the correlation between the dose of antipsychotics and each measure derived from these psychometric tests. The student t-test was used to compare scores obtained from psychometric tests between patients receiving typical and atypical antipsychotics. Results showed significant correlations between chlorpromazine (CPZ)-equivalent doses of typical antipsychotics and atypical antipsychotics, and the total BPRS score and BPRS subscale scores for positive symptoms. CPZ-equivalent doses of typical antipsychotics were correlated with the JSQLS subscale score for dysfunction of psycho-social activity and DIEPSS score. Furthermore, the total BPRS scores, BPRS subscale score for positive symptoms, the JSQLS subscale score for dysfunction of psycho-social activity, and the DIEPSS score were significantly higher in patients receiving typical antipsychotics than atypical antipsychotics. Conclusion and Significance These findings suggest that long-term administration of typical antipsychotics has an unfavorable association with feelings of difficulties mixing in social situations in patients with chronic schizophrenia.

    A substantial portion of men treated for prostate cancer report clinically significant sleep problems and disturbance in sleep quality constitutes significant risk for the development of depressive symptoms in survivors. Dysregulation in biological stress processes underlies the impact of poor sleep on the onset and/or progression of depressive symptoms, yet few studies have sought to identify potential neurobiological mechanisms (e.g., HPA axis activation) underlying this association in PC survivors. The present study examines the relationships between sleep disturbance, depressive symptoms, and indices of diurnal cortisol patterns among men treated for prostate cancer. In total, 66 men (84.8% White; mean age = 65.8 years, SD = 9.04) treated in the prior 2 years for localized prostate cancer were recruited. They completed questionnaires to measure sleep quality and depressive symptoms at study entry (T1) and 4 months later (T2). They also provided 4 saliva samples per day, over 3 days, at T1. Three cortisol indices were computed: diurnal slope, area under the curve (AUCg), and cortisol awakening response (CAR). Analyses indicate that, controlling for body mass index and age, worse sleep quality at T1 was significantly associated with higher levels of depressive symptoms at T2. Significant indirect effects were observed for cortisol slope (indirect effect = -.17, 95% CI [-.61, -.01]) and AUCg (indirect effect = -.14, 95% CI [-.43, -.01]), but not CAR. Results suggest that dysregulation in HPA activity acts as a neurobiological mechanism of the impact of sleep disruption on depressive symptoms in men with prostate cancer.

    Background. Management of individual triggers is suboptimal in practice. In this project, we investigated the impact of symptom perception interventions on asthma trigger identification and self-reported asthma quality of life. Methods. Children with asthma (n = 227) participated in three asthma education sessions and then were randomized first to one of three home monitoring conditions (symptom monitoring and peak flow training with feedback, peak flow training without feedback, or no peak flow training) and then subsequently to one of three resistive load discrimination training conditions (signal detection training with feedback, signal detection training without feedback, or no training). Triggers were reported at enrollment, following home monitoring, and following discrimination training; quality of life was measured after home monitoring and after resistive load testing. Results. Symptom perception interventions resulted in increases in reported triggers, which increased reliably as a function of home monitoring, and increased further in participants who completed discrimination training with feedback. Increases in the number of reported asthma triggers were associated with decreases in quality of life. Discussion. Patients may benefit from strategies that make trigger-symptom contingencies clear. Complementary strategies are needed to address changes in the perceived burden of asthma which comes from awareness of new asthma triggers. PMID:26605084

    This study (a) assessed whether child neglect is associated with posttraumatic stress disorder (PTSD) and dissociative symptoms in the preschool period and (b) examined the role of quality of mother-child affective communication in the development of trauma-related symptoms among neglected children. Participants were 33 neglected and 72 non-neglected preschoolers (mean age = 60 months). Neglected children were recruited from the Child Protection Agencies. Neglected and non-neglected children victims of other form of abuse were excluded from the study. Trauma symptoms were evaluated through mother and preschool teacher reports. Quality of mother-child affective communication was assessed in a lab visit during an unstructured task. According to teachers, neglected children displayed more PTSD and dissociative symptoms than non-neglected children. Quality of mother-child communication was lower in neglected dyads. Mother-child affective communication predicted teacher-reported child trauma symptomatology, over and above child neglect. Discussion focuses on the traumatic nature of child neglect and the underlying parent-child relational processes. PMID:20930179

    BACKGROUND AND OBJECTIVES: Data from a randomized, controlled study of adenotonsillectomy for obstructive sleep apnea syndrome (OSAS) were used to test the hypothesis that children undergoing surgery had greater quality of life (QoL) and symptom improvement than control subjects. The objectives were to compare changes in validated QoL and symptom measurements among children randomized to undergo adenotonsillectomy or watchful waiting; to determine whether race, weight, or baseline OSAS severity influenced changes in QoL and symptoms; and to evaluate associations between changes in QoL or symptoms and OSAS severity. METHODS: Children aged 5 to 9.9 years with OSAS (N = 453) were randomly assigned to undergo adenotonsillectomy or watchful waiting with supportive care. Polysomnography, the Pediatric Quality of Life inventory, the Sleep-Related Breathing Scale of the Pediatric Sleep Questionnaire, the 18-item Obstructive Sleep Apnea QoL instrument, and the modified Epworth Sleepiness Scale were completed at baseline and 7 months. Changes in the QoL and symptom surveys were compared between arms. Effect modification according to race and obesity and associations between changes in polysomnographic measures and QoL or symptoms were examined. RESULTS: Greater improvements in most QoL and symptom severity measurements were observed in children randomized to undergo adenotonsillectomy, including the parent-completed Pediatric Quality of Life inventory (effect size [ES]: 0.37), the 18-item Obstructive Sleep Apnea QoL instrument (ES: –0.93), the modified Epworth Sleepiness Scale score (ES: –0.42), and the Sleep-Related Breathing Scale of the Pediatric Sleep Questionnaire (ES: –1.35). Effect modification was not observed by obesity or baseline severity but was noted for race in some symptom measures. Improvements in OSAS severity explained only a small portion of the observed changes. CONCLUSIONS: Adenotonsillectomy compared with watchful waiting resulted in significantly

    The features of liquid purification from molecular and dispersive admixtures are studied. The analysis has revealed the processes (thermal effects, microparticles heating with a subsequent optical breakdown, Stimulated Raman Scattering) limiting pumping pulse energy. These effects complicate also a realization of a high quality phase conjugation at SBS. The data concerning physical properties of liquid tetrachlorides and freons are presented. The picture of a behavior of liquid under conditions of an optical breakdown is described. Some recommendations regarding a choice of nonlinear media are formulated. The two-cell scheme providing a phase conjugation of powerful short laser pulses is proposed. This is important in the field of inertial confinement fusion.

    Extending research based on different-sex (i.e., heterosexual) couples, the authors explored associations between romantic relationship quality and depressive symptoms in a geographically diverse sample (N = 571) of U.S. adults in same-sex relationships. The authors also examined whether this association was moderated by individual characteristics (gender, age, and internalized heterosexism) or relationship factors (relationship length, commitment, and interdependence). Results indicated a moderate negative association between relationship quality and depressive symptoms, echoing findings from different-sex couples. This association was not moderated by gender, age, internalized heterosexism, or relationship length. In contrast, commitment and interdependence did demonstrate moderating effects. Although the negative association between relationship quality and depressive symptoms was present at all levels of commitment and interdependence, it was amplified at higher commitment and interdependence levels. In general, findings contribute to a growing literature suggesting many commonalities between same-sex and opposite sex couples. Specifically, they suggest the importance of relationship quality to the emotional well-being of LGBT adults, supporting clinical interventions and social policies that promote healthy and stable same-sex relationships.

    Objectives: To determine sleep habits and sleep quality in medical students during their clinical years using validated measures; and to investigate associations with academic performance and psychological stress. Methods: In this cross-sectional study, medical students (n=320) were randomly selected from a list of all enrolled clinical-year students in a Saudi medical school from 2011-2012. Students filled a questionnaire including demographic and lifestyle factors, Pittsburgh Sleep Quality Index, Epworth Sleepiness Scale, and Perceived Stress Scale. Results: Students acquired on average, 5.8 hours of sleep each night, with an average bedtime at 01:53. Approximately 8% reported acquiring sleep during the day, and not during nighttime. Poor sleep quality was present in 30%, excessive daytime sleepiness (EDS) in 40%, and insomnia symptoms in 33% of students. Multivariable regression models revealed significant associations between stress, poor sleep quality, and EDS. Poorer academic performance and stress were associated with symptoms of insomnia. Conclusion: Sleep deprivation, poor sleep quality, and EDS are common among clinical years medical students. High levels of stress and the pressure of maintaining grade point averages may be influencing their quality of sleep. PMID:26837401

    Although lymphedema of the arm is a well-known complication of breast and axillary surgery, breast lymphedema has received scant attention. We sought to prospectively characterize breast lymphedema's incidence, associated symptoms, clinical course, and impact on quality of life. Subjects were enrolled prospectively from a consecutive sample of patients undergoing non-mastectomy breast procedures (excisional biopsy or wide local excision ± lymph node removal) and followed for signs and symptoms of lymphedema in the operated breast. Symptoms and distress were serially assessed with 11-point linear analog scales. Breast lymphedema was diagnosed independent of symptoms, based on the distribution and degree of edema and erythema. One hundred twenty-four women were followed for a median of 11 months, and breast lymphedema was diagnosed in 38 (31%) women. Breast lymphedema was more frequent after breast surgery with axillary node removal (49%) compared to breast surgery alone (0%), p < 0.0001. Breast lymphedema involved multiple quadrants in most women and was characterized by edema in 100% and erythema in 79%. Patients with breast lymphedema were significantly more likely than women without breast lymphedema to report symptoms of breast heaviness (65% vs 22%, p < 0.0001), redness (62% vs 29%, p = 0.0006), and swelling (59% vs 22%, p < 0.0001), but symptom-associated distress was low overall. Three of 32 breast lymphedema patients with clinical follow-up developed chronic edema. Breast lymphedema occurs in approximately one-half of women who undergo breast surgery with axillary node removal. The condition is characterized by diffuse skin edema and erythema as well as self-reported symptoms with a low level of distress. PMID:22415476

    Evaluation of postnatal quality of life (QOL) has remained a poorly researched area in India. The present cross-sectional study assessed postnatal QOL, using the Mother Generated Index (MGI) and its associated risk factors, and was conducted during January-March 2013 among 274 mothers, 6-8 weeks postnatally. A semi-structured questionnaire was used to evaluate sociodemographic and obstetric characteristics and social support. Depressive symptoms were assessed by the Patient Health Questionnaire (PHQ-9) and QOL using the MGI. The vast majority (90.1 percent) of respondents in our study had a primary MGI score <5, those with significantly higher prevalence of physical problems and psychological distress. A total of 39.8 percent of respondents were screened as having other (not major) depressive symptoms and 4.7 percent as having major depressive symptoms. Multiple regression analysis revealed that age (β = 0.033, p = .018) and socioeconomic status (β = 0.156, p < .001) were significantly positively associated with QOL, while increased depressive symptom scores (β = -0.075, p < .001) were significantly negatively associated with QOL. A wide spectrum of QOL aspects were reported, including physical, emotional, social, and economic concerns by the mothers. Prevention, evaluation, and treatment of postnatal depressive symptoms and impaired QOL are warranted, taking into account the role of various biopsychosocial risk factors and specific concerns raised by the mothers.

    Patients with chronic myeloid leukemia (CML) in chronic phase are living longer on BCR-ABL1 tyrosine kinase inhibitor (TKI) therapy, placing emphasis on issues related to symptom burden and quality of life (QoL). Furthermore, the potential for adverse events with longer-term therapy may result in dose adjustments, treatment discontinuation, or nonadherence, all of which may negatively affect treatment efficacy and QoL. However, instruments to specifically measure the impact of symptom burden and treatment on health-related QoL in patients with CML have not been widely available until recently. The FACT-Leu is a validated tool that measures leukemia-specific and more general QoL concerns. Other tools specific to CML, including the MDASI-CML and the EORTC QLQ-CML24, are undergoing validation. Here, we describe TKI therapy-related symptom burden and its effect on adherence and treatment response, outline instruments to measure symptom burden and QoL in CML, and summarize the available clinical data on QoL of patients on TKI therapy. QoL is an aspect of CML disease management that will continue to gain prominence in the coming years. We believe that the instruments developed now will have a role in informing treatment decisions in routine practice and allowing clinicians to proactively address issues related to symptom burden and QoL.

    A body of literature now exists, which demonstrates that idiopathic Parkinson's disease (PD) has a major negative impact on quality of life (QoL), and that depression and cognitive impairment are among the main predictors of poor QoL in this disorder. Relatively little work has been done to assess the differential contribution of the specific symptoms of PD to QoL, which was the aim of this study. One hundred thirty patients with PD completed a booklet of questionnaires, which included the PDQ39 as a disease-specific measure of QoL, a symptom checklist, a mobility checklist, as well as patient ratings of disease stage and disability. The results indicated that the contribution of physical, medication-related, and cognitive/psychiatric symptoms to QoL can be significant. Sudden unpredictable on/off states, difficulty in dressing, difficulty in walking, falls, depression, and confusion were PD symptoms, which significantly influenced QoL scores. Among the mobility problems associated with PD, start hesitation, shuffling gait, freezing, festination, propulsion, and difficulty in turning had a significant effect on QoL scores. In addition to depression and anxiety, the major predictors of QoL were shuffling, difficulty turning, falls, difficulty in dressing, fatigue, confusion, autonomic disturbance particularly urinary incontinence, unpredictable on/off fluctuations, and sensory symptoms such as pain. The implications of these results for the medical management of PD are discussed. PMID:18543333

    Two studies examined associations between social networking and depressive symptoms among youth. In Study 1, 384 participants (68% female; mean age = 20.22 years, SD = 2.90) were surveyed. In Study 2, 334 participants (62% female; M age = 19.44 years, SD = 2.05) were surveyed initially and 3 weeks later. Results indicated that depressive symptoms were associated with quality of social networking interactions, not quantity. There was some evidence that depressive rumination moderated associations, and both depressive rumination and corumination were associated with aspects of social networking usage and quality. Implications for understanding circumstances that increase social networking, as well as resulting negative interactions and negative affect are discussed. PMID:24490122

    Browning disorder, which usually occurs post-harvest in pears subjected to long-term storage, can cause browning of the pear flesh and/or core. In 2011, investigators in China found a novel type of brown spot (designated as surface brown spot, SBS) in pre-harvest ‘Dangshansuli’ pears (Pyrus bretschneideri Rehd.). SBS has a large impact on the exterior quality of the pears. Interestingly, the brown coloration was only found on the peel and not the flesh or the core. In this paper, de novo transcriptome analysis of the exocarp of pears with SBS using Illumina sequencing showed that SBS up-regulated the expression of genes related to oxidative phosphorylation, phenolic compound synthesis and polyphenoloxidase (PPO), and SBS was associated with inhibition of primary and secondary metabolism genes. Ca2+-sensor proteins might be involved in the signal transduction that occurs during the process of SBS formation, and this signaling is likely to be regulated by H2O2, abscisic acid (ABA) and gibberellic acid (GA3). Phytohormone and mineral element analyses confirmed that GA3, ABA, H2O2 and Ca2+ contribute to SBS formation. In addition to the seasonal characteristics, low levels of O2 and Ca2+ in the fruit are potential causes of the browning response due to exposure to oxidative stress, oxidative-reductive imbalance and the accumulation of reactive oxygen species (ROS), which affected the membrane integrity. Disruption of the membranes allows for PPO and phenolic compounds to come into contact, and the phenolic compounds are oxidized to form the browning pigments. PMID:24058529

    This study examined the relationship between peritraumatic reactions, posttraumatic stress disorder (PTSD) symptoms, somatic complaints, and quality of life in Tunisians exposed to the events of the Arab Spring. Participants (n = 60) completed an online survey 1 year after the events, assessing peritraumatic distress, peritraumatic dissociation, PTSD symptoms, somatic complaints, and physical and mental quality of life. Results showed that peritraumatic dissociation was independently associated with increased PTSD symptoms and somatic complaints 12 months after the events. Multiple mediator mediation analyses revealed that somatic complaints (not PTSD symptoms) were the only independent mediators of the relationships between peritraumatic dissociation and both physical and mental quality of life. Assessing peritraumatic dissociation soon after trauma exposure among the North African population might help identify individuals at risk for PTSD. Furthermore, the impact of trauma on quality of life may be better explained by somatic complaints than PTSD symptoms among North Africans. PMID:26825265

    Background Concerns are present on the limited value of renal function alone in defining the optimal moment to start dialysis. Disease-related symptoms and health-related quality of life (HRQOL) may have additional clinical value in defining this moment, but little is known about how these parameters change during pre-dialysis care. The aims of our study were to describe the course of symptoms and HRQOL during pre-dialysis care and to investigate their association with poor health outcomes. Methods In the prospective PREPARE-2 cohort, incident patients starting specialized pre-dialysis care were included when referred to one of the 25 participating Dutch outpatient clinics (2004–2011). In the present analysis, 436 patients with data available on symptoms and HRQOL were included. Clinical data, symptoms (revised illness perception questionnaire), and HRQOL (short form-36 questionnaire; physical and mental summary score) were collected every 6-month interval. A time-dependent Cox proportional hazard model was used to associate symptoms and HRQOL with the combined poor health outcome (i.e. starting dialysis, receiving a kidney transplant, and death). Results All symptoms increased, especially fatigue and loss of strength, and both the physical and mental summary score decreased over time, with the most pronounced change during the last 6–12 months of follow-up. Furthermore, each additional symptom (adjusted HR 1.04 (95% CI, 1.00–1.09)) and each 3-point lower physical and mental summary score (adjusted HR 1.04 (1.02–1.06) and 1.04 (1.02–1.06) respectively) were associated with a higher risk of reaching the combined poor health outcome within the subsequent 6 months. Conclusions The number of symptoms increased and both the physical and mental HRQOL score decreased during pre-dialysis care and these changes were associated with starting dialysis, receiving a kidney transplant, and death. These results may indicate that symptoms and HRQOL are good markers for

    The nationwide prevalence of major depressive disorder in Korea is lower than most countries, despite the high suicide rate. To explain this unexpectedly low prevalence, we examined the functional disability and quality of life in community-dwelling subjects with significant depressive symptoms not diagnosable as depressive disorder. A total of 1,029 subjects, randomly chosen from catchment areas, were interviewed with the Center for Epidemiologic Studies Depression scale, Mini International Neuropsychiatric Interview, WHO Quality of Life scale, and the WHO Disability Assessment Schedule. Those with scores over 21 on the depression scale were interviewed by a psychiatrist for diagnostic confirmation. Among community-dwelling subjects, the 1-month prevalence of major depressive disorder was 2.2%, but the 1-month prevalence of depressive symptoms not diagnosable as depressive disorder was 14.1%. Depressive disorders were the cause of 24.7% of work loss days, while depressive symptoms not diagnosable as depressive disorder were the cause of 17.2% of work loss days. These findings support the dimensional or spectrum approach to depressive disorder in the community and might be the missing link between the apparent low prevalence of depressive disorder and high suicide rate in Korea.

    The effect of an oral sustained release beta 2 agonist on symptoms, sleep quality, and peak flow rates has been studied in nine patients with nocturnal asthma. Patients received oral terbutaline 7.5 mg twice daily or placebo for seven days in a double blind crossover study and spent the last two nights of each limb in a sleep laboratory. Oral terbutaline improved morning peak flow (259 v 213 l min-1) and decreased nocturnal inhaler usage (1.3 v 1.9) with no alteration in sleep quality as assessed electroencephalographically. The study shows that oral sustained release terbutaline can be useful in the treatment of nocturnal asthma without impairment of sleep quality. PMID:3321540

    A stimulated Brillouin scattering (SBS) phase conjugate laser mirror uses a solid-state nonlinear gain medium instead of the conventional liquid or high pressure gas medium. The concept has been effectively demonstrated using common optical-grade fused silica. An energy threshold of 2.5 mJ and a slope efficiency of over 90% were achieved, resulting in an overall energy reflectivity of >80% for 15 ns, 1 um laser pulses. The use of solid-state materials is enabled by a multi-pass resonant architecture which suppresses transient fluctuations that would otherwise result in damage to the SBS medium. This all solid state phase conjugator is safer, more reliable, and more easily manufactured than prior art designs. It allows nonlinear wavefront correction to be implemented in industrial and defense laser systems whose operating environments would preclude the introduction of potentially hazardous liquids or high pressure gases. 8 figs.

    PURPOSE: To examine the relationship between clinical measures of visual function and patient-reported measures of symptoms and health status in a large cohort of glaucoma patients at the time of diagnosis. SUBJECTS AND METHODS: The 607 patients in the Collaborative Initial Glaucoma Treatment Study (CIGTS) received standardized examinations of visual acuity and visual field at enrollment. In addition, they completed a health-related quality-of-life instrument, which included the Visual Activities Questionnaire (VAQ), Sickness Impact Profile (SIP), a symptom and a comorbidity chart, a question about their degree of worry about becoming blind, and many other items. RESULTS: The SIP total and dimension scores correlated only weakly, and not significantly, with visual acuity and visual field measures. The VAQ total and subscale scores, particularly the peripheral vision subscale, correlated weakly and significantly with visual acuity and visual field scores, especially those from the better eye. Worry about blindness and symptoms attributed to glaucoma correlated weakly but significantly to visual field scores from the worse eye. Attempts to improve correlations by scoring the visual fields differently, including only paracentral and pericentral test locations in the scores, and simulating binocular visual field scores were largely unsuccessful. CONCLUSIONS: At diagnosis, most patients were relatively free of glaucoma-induced impairments, so clinical measures were poor predictors of a patient's perception of health-related quality of life. The vision-specific VAQ and glaucoma-related symptom score correlated better than the generic SIP with clinical measures at the time of enrollment into CIGTS. PMID:10360308

    Introduction: Wilson’s disease is an inherited disorder caused by a gene located on chromosome 13, which involved copper transportation across cell membranes. The disease can cause a reduced incorporation of copper into ceruloplasmin resulting in accumulation of this metal in the liver, central nervous system, kidneys and other organs. The objective is to define the frequencies of psychiatric disorders in WD, the amount of impairment of Quality of Life [QoL] in patients with WD and the relevance of the psychiatric disorders in the QoL of people suffering by WD. Methods: This is a systematic review. The search of the significant articles was carried out in PubMed using specific key words. Results: Such other neurological diseases, WD is characterized by chronic course and need of treatments, impairment of functional outcomes and high frequency of psychiatric symptoms, although a specific association between Bipolar Disorders and WD was recently found. Despite this, since today few studies are carried on WD patients’ quality of life related to psychiatric symptoms. Some new reports showed a link between presence of Bipolar Disorders diagnosis, cerebral damage and low Qol. Conclusion: Prospective studies on large cohorts are required to establish the effective impact of psychiatric disorders comorbidity, particularly Bipolar Disorders, on quality of life in WD and to clarify the causal link between brain damage, psychiatric disorders and worsening of QoL.

    Background. Only some studies provide sufficient data regarding the effects of nonpostbariatric (aesthetic) abdominoplasty on various aspects of quality of life. Nevertheless, when considering the effects on eating habits, publications are lacking. Therefore we decided to assess the effects of nonpostbariatric abdominoplasty on eating disorder symptoms, psychological distress, and quality of life. Materials and Methods. 64 consecutive women underwent nonpostbariatric abdominoplasty. Three outcome measures were completed: the Eating Disorder Inventory (EDI), Raitasalo's modification of the Beck Depression Inventory (RBDI), and the 15D general quality of life questionnaire. Results. The mean age at baseline was 42 years and the mean body mass index (BMI) 26.4. Fifty-three (83%) women completed all the outcome measures with a mean follow-up time of 5 months. A significant improvement from baseline to follow-up was noted in women's overall quality of life, body satisfaction, effectiveness, sexual functioning, and self-esteem. The women were significantly less depressive and had significantly less drive for thinness as well as bulimia, and their overall risk of developing an eating disorder also decreased significantly. Conclusions. Abdominoplasty results in significantly improved quality of life, body satisfaction, effectiveness, sexual functioning, self-esteem, and mental health. The risk of developing an eating disorder is decreased significantly. This trial is registered with Clinicaltrials.gov NCT02151799. PMID:25506426

    The grafting of 4-vinyl pyridine (VP) to styrene-butadienestyrene triblock copolymer (SBS) by radiation-induced graft copolymerization was studied. The cohesive properties such as cohesive energy (Ecoh), molar volume (V), solubility parameter (delta), molar molecular weight (WM), specific volume (Vg), and density (1/Vg) of SBS-g-VP graft copolymer were calculated according to the group contribution of Fedors. The morphology of SBS-g-VP was studied by optical polarizing microscopy. We also measured the glass transition temperature and the mechanical properties of SBS-g-VP graft copolymer. Contact angle and blood-clotting time experiments were also performed to evaluate the biocompatibility of SBS-g-VP. A second domain was found in the SBS-g-VP graft copolymer, which resulted in different properties between SBS-g-VP and SBS. The blood compatibility of SBS-g-VP as measured by the Lee-White clotting test was better than that of SBS and polystyrene. PMID:8731218

    A styrene-butadiene-styrene triblock copolymer (SBS) membrane was prepared by solvent casting. Grafting of dimethyl amino ethyl methacrylate (DMAEMA) to this SBS membrane was subsequently conducted by ultraviolet radiation-induced graft copolymerization without degassing to obtain a SBS-g-DMAEMA copolymer membrane. The graft copolymer was characterized by infrared spectroscopy and scanning electron microscopy. The degree of grafting and the mechanical properties of SBS and SBS-g-DMAEMA were measured. Contact angle, water content, and protein absorption of fibrinogen and albumin experiments were also performed to evaluate the biocompatibility of SBS-g-DMAEMA graft copolymer membranes. It was found that the degree of grafting was related to the irradiation time, DMAEMA concentration, and temperature. The tensile strength of the SBS-g-DMAEMA membrane increased with an increase in the degree of grafting. By using Kaelble's equation and the contact angle data, the surface tension of SBS-g-DMAEMA was determined. It was found that with an increase in the degree of grafting, the surface tension and water content of SBS-g-DMAEMA membrane increased, whereas the contact angle decreased. The amount of absorption of albumin and fibrinogen decreased with an increase in amount of grafting. However, there was a minimum for the adsorption of proteins in the SBS-g-DMAEMA membrane.

    A high prevalence of abuse has been reported in patients with fibromyalgia. We aimed to examine the association between self-reported abuse history and symptom severity and quality of life (QOL) in 962 patients with fibromyalgia. All patients completed the Fibromyalgia Impact Questionnaire (FIQ) and the Short Form 36 health survey (SF-36). Multivariate regression analyses were performed. In total, 289 patients (30%) reported a history of abuse. Of those who specified abuse types, 161 patients (59%) reported more than 1 type of abuse (36% emotional, 32% physical, 25% sexual, and 7% verbal). Patients in the abuse group were younger and more likely to be female, unemployed, unmarried, and current smokers compared with patients who reported no abuse. After adjusting for these differences, abuse history was associated with worse symptoms, as indicated by a higher FIQ total score (P < .001) and higher FIQ subscale scores in physical function (P = .001), work missed (P < .001), job ability (P < .001), pain (P = .02), depression (P < .001), and anxiety (P < .001). Similarly, abuse history was associated with worse QOL, with lower SF-36 scores in all domains except the physical component summary. In conclusion, abuse history in patients with fibromyalgia was associated with worse symptoms and QOL compared with those patients without abuse history. Future studies are needed to assess whether additional tailored interventions as part of fibromyalgia treatment are helpful for patients with a history of abuse. PMID:25129032

    Vitamin D plays an important role in the immune system; decreased serum vitamin D concentrations have been linked to dysregulated immune function. Low vitamin D status is probably associated with chronic spontaneous urticaria (CSU). We evaluated the prevalence of low vitamin D status, and the clinical response and quality of life following vitamin D supplementation, in a prospective case-control study with 60 CSU patients and 40 healthy individuals. Serum 25-hydroxy vitamin D (25(OH)D) concentrations were measured at baseline and after 6 weeks. For patients with 25(OH)D concentrations < 30 ng/ml, treatment included 20,000 IU/day of ergocalciferol (vitamin D2) and non-sedative antihistamine drugs for 6 weeks. Urticaria symptom severity and quality of life were assessed based on the Urticaria Activity Score over 7 days (UAS7) and the Dermatology Life Quality Index (DLQI). Of the 100 participants, 73% were female; the mean age was 39 ± 16 years. Vitamin D deficiency (measured as 25(OH)D < 20 ng/ml) was significantly higher in the CSU group than the control group. The median 25(OH)D concentration for the CSU group, 15 (7 - 52) ng/ml was significantly lower than for control group, 30 (25 - 46) ng/ml. Overall, 83% (50/60) of CSU patients (25(OH)D < 30 ng/ml) were treated with ergocalciferol (vitamin D2) supplementation; after 6 weeks, these patients showed significant improvements in UAS7 and DLQI scores compared with the non-vitamin D supplement group. This study revealed a significant association of lower serum 25(OH)D concentrations with CSU. Vitamin D supplements might improve symptoms and quality of life in CSU patients. PMID:25346784

    A cross-sectional survey was conducted to characterize the indoor air quality (IAQ) in schools and its relationship with children's respiratory symptoms. Concentrations of volatile organic compounds (VOC), aldehydes, PM2.5, PM10, carbon dioxide, bacteria and fungi were assessed in 73 classrooms from 20 public primary schools located in Porto, Portugal. Children who attended the selected classrooms (n = 1134) were evaluated by a standardised health questionnaire completed by the legal guardians; spirometry and exhaled nitric oxide tests. The results indicated that no classrooms presented individual VOC pollutant concentrations higher than the WHO IAQ guidelines or by INDEX recommendations; while PM2.5, PM10 and bacteria levels exceeded the WHO air quality guidelines or national limit values. High levels of total VOC, acetaldehyde, PM2.5 and PM10 were associated with higher odds of wheezing in children. Thus, indoor air pollutants, some even at low exposure levels, were related with the development of respiratory symptoms. The results pointed out that it is crucial to take into account the unique characteristics of the public primary schools, to develop appropriate control strategies in order to reduce the exposure to indoor air pollutants and, therefore, to minimize the adverse health effects.

    Underemployed workers-those receiving less pay, working fewer hours, or using fewer skills than they would prefer-appear to experience negative mental health outcomes similar to the unemployed. Prior cross-sectional research provides mixed empirical evidence for this conclusion, however. The current study sought to clarify the impact of underemployment longitudinally, assessing mental health 5 times over 8 months after job loss. In addition to the commonly used indicators of underemployment, we designed a measure of cognitive complexity using the Occupational Information Network (O*NET), an extensive government database used to organize and categorize occupational information. Replicating past research, we found concurrent associations between all indexes of reemployment job quality and internalizing symptoms in the period immediately after reemployment. However, when controlling for quality of prior employment, all indicators except our measure for cognitive complexity became nonsignificant. As participants transitioned from unemployment to reemployment, only reductions in cognitive complexity were associated with sustained general internalizing symptoms. We also found that although changes in cognitive complexity had an immediate impact on the well-being of the recently reemployed, only the number of available weekly hours (full-time vs. part-time status) was relevant 6 to 12 weeks later. Our longitudinal model thus provides significant nuance to the current understanding of underemployment and mental health. PMID:25151465

    Objectives Menopause is associated with somatic, vasomotor, psychological, and sexual complaints that may affect quality of life. We determined the prevalence and severity of menopausal symptoms and their impact on the quality of life among Saudi women visiting primary care centers in Riyadh, Saudi Arabia. Methods A cross-sectional study was conducted from October to November 2010. In total, 119 women aged 45–60 years were randomly interviewed using a questionnaire. Participants were divided into three categories: premenopausal (n=31), perimenopausal (n=49), and postmenopausal (n=39). The Menopause Rating Scale (MRS) assessed the prevalence and severity of eleven menopausal symptoms. Mean scores of menopausal categories were compared for different symptoms. Results The mean age at menopause was 48.3±3 years (median, 49 years). The symptoms reported to be most prevalent were joint and muscle pain (80.7%), physical and mental exhaustion (64.7%), and hot flushes and sweating (47.1%). Somatic and psychological symptoms were highly prevalent in perimenopausal women compared to other groups. The mean overall quality-of-life score was higher in perimenopausal women, while the total MRS score indicated that the symptoms were mild in severity (MRS <9). Conclusion The prevalence of menopausal symptoms was comparable to previous studies in Asian women; however, the prevalence of classic symptoms of hot flushes and night sweats was lower than reported in Western studies. Saudi women reported an MRS score indicating milder severity of symptoms, reflecting better quality of life and ability to cope with climacteric symptoms. PMID:26170720

    Study Objectives: Determine effects of low-dose estradiol and low-dose venlafaxine on self-reported sleep measures in menopausal women with hot flashes. Design: 3-arm double-blind randomized trial. Participants assigned in a 2:2:3 ratio to 17β estradiol 0.5 mg/day (n = 97), venlafaxine XR 75 mg/day (n = 96), or placebo (n = 146) for 8 weeks. Setting: Academic research centers. Participants: 339 community-dwelling perimenopausal and postmenopausal women with ≥ 2 bothersome hot flashes per day. Measurements and Results: Insomnia symptoms (Insomnia Severity Index [ISI]) and sleep quality (Pittsburgh Sleep Quality Index [PSQI]) at baseline, week 4 and 8; 325 women (96%) provided ISI data and 312 women (92%) provided PSQI data at baseline and follow-up. At baseline, mean (SD) hot flash frequency was 8.1/day (5.3), mean ISI was 11.1 (6.0), and mean PSQI was 7.5 (3.4). Mean (95% CI) change from baseline in ISI at week 8 was −4.1 points (−5.3 to −3.0) with estradiol, −5.0 points (−6.1 to −3.9) with venlafaxine, and −3.0 points (−3.8 to −2.3) with placebo (P overall treatment effect vs. placebo 0.09 for estradiol and 0.007 for venlafaxine). Mean (95% CI) change from baseline in PSQI at week 8 was −2.2 points (−2.8 to −1.6) with estradiol, −2.3 points (−2.9 to −1.6) with venlafaxine, and −1.2 points (−1.7 to −0.8) with placebo (P overall treatment effect vs. placebo 0.04 for estradiol and 0.06 for venlafaxine). Conclusions: Among perimenopausal and postmenopausal women with hot flashes, both low dose oral estradiol and low-dose venlafaxine compared with placebo modestly reduced insomnia symptoms and improved subjective sleep quality.

    This study was designed to examine interactions between psychosocial risk (i.e., maternal depressive symptoms) and protective (i.e., child coping skills and mother-child relationship quality) correlates of depressive symptoms among inner-city African American children of mothers with and without HIV/AIDS. Two primary hypotheses were tested: (a) whether these correlates interact differently in HIV-infected and noninfected samples and (b) whether child coping skills and a positive mother-child relationship interact to protect children from developing depressive symptoms in the context of maternal HIV infection. Results indicated that (a) a positive mother-child relationship, but not child coping skills, was protective in the HIV-infected sample when maternal depressive symptoms were high and (b) the combination of a positive mother-child relationship and child coping skills was associated with the lowest level of child depressive symptoms in the HIV-infected sample. These findings highlight the differential importance of various risk and protective mechanisms for HIV-infected and noninfected African American samples and, as such, have preventative implications for children of HIV-infected women.

    An approach that introducing a standing wave into focal area to stabilize the output energy and duration of stimulated Brillouin scattering (SBS) compression is presented. An interferometric scheme filled with FC-770 is used to improve the stability of both output energy and duration two times compared with an equivalent conventional SBS compressor. Moreover, the interferometric scheme shows a promotion for the performance of SBS compression.

    The present work has the objective of analyzing blends of PP with 30 wt% SBS vulcanized with gamma irradiation. In order to do so, SBS was irradiated at 10, 25 and 50 kGy with gamma rays. Results indicate that the gel fraction increases with irradiation dose, varying from 0.3% to 13.0% for the doses employed. Concerning tensile properties, it can be seen that the incorporation of SBS non-irradiated or irradiated decreases Young's modulus, while increasing elongation at break. Respect to thermal studies, it was detected that SBS decreases melting enthalpy of blends, fact that implies a decrease on crystallinity degree, being this effect more noticeable when SBS is irradiated at doses higher than 10 kGy. On the other hand, melting temperature diminishes slightly when adding SBS to PP, but does not show significant variations when SBS is irradiated. PPs MFI decreased with the addition of SBS, being the effect more notorious with irradiation dose. Finally, it can be concluded that SBS can be vulcanized by gamma irradiation, and that the crosslinking degree increases with irradiation dose.

    Data from published studies were combined and analyzed to develop best-fit equations and curves quantifying the change in sick building syndrome (SBS) symptom prevalence with ventilation rate. For each study, slopes were calculated, representing the fractional change in SBS symptom prevalence per unit change in ventilation rate per person. Values of ventilation rate, associated with each value of slope, were also calculated. Linear regression equations were fit to the resulting data points, after weighting by study size. Integration of the slope-ventilation rate equations yielded curves of relative SBS symptom prevalence versus ventilation rate. Based on these analyses, relative SBS symptom prevalence increases approximately 23percent (12percent to 32percent) as the ventilation rate drops from 10 to 5 L/s-person and relative prevalence decreases approximately 29percent (15percent to 42percent) as ventilation rate increases from 10 to 25 L/s-person.

    BACKGROUND: COPD includes the chronic bronchitis (CB) and emphysema phenotypes. Although it is generally assumed that emphysema or chronic airflow obstruction (CAO) is associated with worse quality of life (QOL) than is CB, this assumption has not been tested. METHODS: The current study’s analyses from the Lovelace Smokers’ Cohort (LSC) were validated in the COPD Gene Cohort (COPDGene). CB without CAO (CB only) was defined as self-reported cough productive of phlegm for ≥ 3 mo/y for 2 consecutive years and postbronchodilator FEV1/FVC ≥ 70%. CAO without CB (CAO only) was defined as a postbronchodilator FEV1/FVC < 70% with no evidence of CB. QOL outcomes were obtained from the St. George’s Respiratory Questionnaire (SGRQ) and the 36-Item Short Form Health Survey (SF-36) questionnaires. A priori covariates included age, sex, pack-years of smoking, current smoking, and FEV1. RESULTS: Smokers with CB without CAO (LSC = 341; COPDGene = 523) were younger and had a greater BMI and less smoking exposure than did those with CAO only (LSC = 302; COPDGene = 2,208). Compared with the latter group, QOL scores were worse for those with CB only. Despite similar SGRQ Activity and SF-36 Role Physical and Physical Functioning, SGRQ Symptoms and Impact scores and SF-36 emotional and social measures were worse in the CB-only group, in both cohorts. After adjustment for covariates, the CB-only group remained a significant predictor for “worse” symptoms and emotional and social measures. CONCLUSIONS: To our knowledge, this analysis is the first to suggest that among subjects with COPD, those with CB only present worse QOL symptoms and mental well-being than do those with CAO only.

    This study used qualitative data collection and analysis methods to describe provider perceptions of addressing patient-initiated communication about common or sensitive symptom and quality of life issues (SQIs) in oncology. Eligible participants were healthcare providers who had participated in a larger trial testing a patient-centered technology to assess cancer SQIs and support self care. Audio-recorded vignettes were simulated based on recorded clinic visits from the larger trial and presented during semi-structured cognitive interviews with each participant. Transcripts of the interviews were content analyzed. Twelve providers participated. Participants’ responses included four themes: the institutional and clinical context, the complexity of addressing SQIs, strategies used to understand SQIs, and creating a plan to address SQIs. Participants felt that approaching SQIs inside and outside of the clinic required ongoing communication within a multidisciplinary team both to gather information and manage the SQI. Forming a relationship with the patient was one strategy to facilitate assessing SQIs. Most participants expressed a need for guidance about effective SQI communication. Providers perceived approaching SQIs as a routine part of interdisciplinary clinical care. The specific symptom and the complexity of its management influenced the process of assessing and managing SQIs. Findings have implications for institutional processes, training, evaluation, and program development. PMID:24748096

    Objective Characterize pelvic floor symptom distress and impact, sexual function and quality of life in women who underwent rectal prolapse surgery. Methods Subjects undergoing rectal prolapse surgery from 2004–2009 completed questionnaires including the Pelvic Floor Distress Inventory, Pelvic Floor Impact Questionnaire, and the Prolapse/Urinary Incontinence Sexual Questionnaire. Baseline demographic, medical, and surgical characteristics were extracted by chart review. Demographic and clinic outcomes of women undergoing transperineal and abdominal approaches were compared. Wilcoxon rank-sum test was used for continuous variables and Fisher’s exact test for categorical measures. Results 45 were identified; two deceased at follow-up. 28/43 subjects (65.1%) responded to the questionnaires. Mean time from original procedure was 3.9 ± 3.1 years. No differences in median total Pelvic Floor Distress Inventory, Pelvic Floor Impact Questionnaire, and subscale scores, and Prolapse/Urinary Incontinence Sexual Questionnaire scores in women undergoing open rectopexy versus transperineal proctectomy were seen (all p>0.05). 26 (60%) participants answered the Prolapse/Urinary Incontinence Sexual Questionnaire, nine reported sexual activity within the last month. All underwent abdominal procedures. Conclusion There are few colorectal or other pelvic floor symptoms after rectal prolapse repair. Robust prospective studies are needed to more fully characterize and understand issues associated with rectal prolapse surgery in women. PMID:25379122

  16. Association between alcohol consumption and symptom severity and quality of life in patients with fibromyalgia

    Introduction Although alcohol consumption is a common lifestyle behavior with previous studies reporting positive effects of alcohol on chronic pain and rheumatoid arthritis, no studies to this date have examined alcohol consumption in patients with fibromyalgia. We examined the association between alcohol consumption and symptom severity and quality of life (QOL) in patients with fibromyalgia. Methods Data on self-reported alcohol consumption from 946 patients were analyzed. Subjects were grouped by level of alcohol consumption (number of drinks/week): none, low (≤3), moderate (>3 to 7), and heavy (>7). Univariate analyses were used to find potential confounders, and analysis of covariance was used to adjust for these confounders. Tukey HSD pairwise comparisons were used to determine differences between alcohol groups. Results Five hundred and forty-six subjects (58%) did not consume alcohol. Low, moderate, and heavy levels of alcohol consumption were reported for 338 (36%), 31 (3%), and 31 patients (3%), respectively. Employment status (P <0.001), education level (P = 0.009), body mass index (P = 0.002) and opioid use (P = 0.002) differed significantly among groups with drinkers having higher education, a lower BMI, and a lower frequency of unemployment and opioid use than nondrinkers. After adjusting for these differences, the measures including the number of tender points (P = 0.01), FIQ total score (P = 0.01), physical function (P <0.001), work missed (P = 0.005), job ability (P = 0.03), and pain (P = 0.001) differed across groups, as did the SF-36 subscales of physical functioning (P <0.001), pain index (P = 0.002), general health perception (P = 0.02), social functioning (P = 0.02), and the physical component summary (P <0.001). Pairwise comparison among the 4 groups showed that the moderate and low alcohol drinkers had lower severity of fibromyalgia symptoms and better physical QOL than nondrinkers. Conclusions Our study demonstrates that low and moderate

    There are limited data on quality of life (QOL) 1 in untreated HIV-infected children who do not have severe HIV symptoms. Moreover, such data do not exist for Asian children. Poor QOL could be a factor in deciding if antiretroviral therapy (ART) should be initiated. Thai and Cambodian children (n=294), aged 1-11 years, naïve to ART, with mild to moderate HIV symptoms and CD4 15-24% were enrolled. Their caregivers completed the Pediatric AIDS Clinical Trials Group QOL questionnaire prior to ART commencement. Six QOL domains were assessed using transformed scores that ranged from 0 to 100. Higher QOL scores indicated better health. Mean age was 6.1 (SD 2.8) years, mean CD4 was 723 (SD 369) cells/mm(3), 57% was female, and%CDC N:A:B was 2:63:35%. One-third knew their HIV diagnosis. Mean (SD) scores were 69.9 (17.6) for health perception, 64.5 (16.2) for physical resilience, 84.2 (15.6) for physical functioning, 77.9 (16.3) for psychosocial well-being, 74.7 (28.7) for social and role functioning, 90.0 (12.1) for health care utilization, and 87.4 (11.3) for symptoms domains. Children with CD4 counts above the 2008 World Health Organization (WHO) ART-initiation criteria (n=53) had higher scores in health perception and health care utilization than those with lower CD4 values. Younger children had poorer QOL than older children despite having similar mean CD4%. In conclusion, untreated Asian children without severe HIV symptoms had relatively low QOL scores compared to published reports in Western countries. Therapy initiation criteria by the WHO identified children with lower QOL scores to start ART; however, children who did not fit ART-initiation criteria and those who were younger also displayed poor QOL. QOL assessment should be considered in untreated children to inform decisions about when to initiate ART. PMID:21777076

    An integration of family systems perspectives with developmental psychopathology provides a framework for examining the complex interplay between family processes and developmental trajectories of child psychopathology over time. In a community sample of 98 families, we investigated the evolution of family relationships, across multiple subsystems of the family (i.e., interparental, mother-child, father-child), and the impact of these changing family dynamics on developmental trajectories of child internalizing symptoms over 6 years, from preschool age to pre-adolescence. Parent–child relationship quality was observed during lengthy sessions, consisting of multiple naturalistic, carefully scripted contexts. Each parent completed reports about interparental relationship satisfaction and child internalizing symptoms. To the extent that mothers experienced a steeper decline in interparental relationship satisfaction over time, children developed internalizing symptoms at a faster rate. Further, symptoms escalated at a faster rate to the extent that negative mother-child relationship quality increased (more negative affect expressed by both mother and child, greater maternal power assertion) and positive mother-child relationship quality decreased (less positive affect expressed by both mother and child, less warmth and positive reciprocity). Time-lagged growth curve analyses established temporal precedence such that decline in family relationships preceded escalation in child internalizing symptoms. Results suggest that family dysfunction, across multiple subsystems, represents a driving force in the progression of child internalizing symptoms. PMID:25790794

    Block copolymers are of both theoretical and practical importance because of their ability to self-assemble in nano-ordered structures. The self-assembly processes in these materials, are a consequence of the intermolecular micro phase separation between the dissimilar chains covalently linked together. Another important property of block copolymers is that, in solution with a selective solvent, they aggregate to form physical gels. Their technological importance is due to their ability to form elastic solids via self-assembly, with midblocks bridging aggregated end-block micelles. In our study poly(styrene-b-butadiene-b-styrene) (SBS), form, by its dissolution in a mid-block-selective solvent (THF) physical gels. So the morphology and the rheological behavior of the thermoreversible gels have been studied and characterized. Moreover, the gel behavior was also studied when Ag nanoparticles were added to the SBS matrix. The results of this study show that the gel stability is not affected by the presence of Ag nanoparticles.

    There is increasing evidence for the role of nutrition in the prevention of depression. This study aims to describe changes in diet quality over 12 years among participants in the Australian Longitudinal Study on Women's Health in relation to changes in depressive symptoms. Women born between 1946 and 1951 were followed-up for 12 years (2001-2013). Dietary intake was assessed using the Dietary Questionnaire for Epidemiological Studies (version 2) in 2001, 2007 and every 2-3 years after that until 2013. Diet quality was summarised using the Australian Recommended Food Score (ARFS). Depressive symptoms were measured using the ten-item Centre for Epidemiologic Depression Scale at every 2-3-year intervals during 2001-2013. Linear mixed models were used to examine trends in diet quality and its sub-components. The same model including time-varying covariates was used to examine associations between diet quality and depressive symptoms adjusting for confounders. Sensitivity analyses were carried out using the Mediterranean dietary pattern (MDP) index to assess diet quality. Minimal changes in overall diet quality and its sub-components over 12 years were observed. There was a significant association between baseline diet quality and depression (β=-0·24, P=0·001), but this was lost when time-varying covariates were added (β=-0·04, P=0·10). Sensitivity analyses showed similar performance for both ARFS and MDP in predicting depressive symptoms. In conclusion, initial associations seen when using baseline measures of diet quality and depressive symptoms disappear when using methods that handle time-varying covariates, suggesting that previous studies indicating a relationship between diet and depression may have been affected by residual confounding.

    Background Children with oppositional defiant symptoms (ODS) are highly related to parental stress, especially in mothers. This study is the first to investigate the quality of life (QOL) of mothers of children with ODS in a community sample. Methods Randomly selected mothers of children attending an elementary school were contacted, and 387 who completed the questionnaire participated in this study. The children's ODS status was determined by the maternal rating of the Chinese Swanson, Nolan, and Pelham rating scale, version IV. The mothers' QOL was estimated by maternal reports from the World Health Organization Quality of Life – BREF (WHOQOL‐BREF) instrument. The relationship between the children's ODS status and maternal QOL was examined by analysis of covariance (ANCOVA) with the participants' sociodemographic factors as covariables. Results Sixty‐three children, mostly boys, met the screening criteria for ODS. The positive screening rate for ODS was 16.49%. The children's ODS status was a significant predictor for the maternal physical capacity, psychological wellbeing and environment domains of QOL. Mothers of children with ODS who rented a house were younger and had lower education levels and worse QOL in all domains. Conclusion A high positive screening rate for ODS children in the elementary school and a relationship between poor maternal QOL and children's ODS were found in this study. Routine screening for ODS in children and mental health services for these children and their mothers are warranted. PMID:22477927

    Living in a lower-quality neighborhood is associated with higher levels of depressive symptoms in the general population as well as among pregnant and postpartum women. However, little is known of the important pathways by which this association occurs. We proposed a model in which perceived stress and social support mediated the effects of neighborhood quality on depressive symptoms during pregnancy (measured by the 20-item Center for Epidemiologic Studies-Depression, CES-D, scale) in a sample of 1383 African American women from the Detroit metropolitan area interviewed during their delivery hospitalization. Using structural equation modeling (SEM), we built a latent variable of neighborhood quality using 4 measures (neighborhood disorder, neighborhood safety/danger, walking environment, overall rating). We then tested two SEM mediation models. We found that lower neighborhood quality was associated with higher prevalence of depressive symptoms during pregnancy (standardized total effect = .16, p = .011). We found that perceived stress partially mediated the neighborhood quality association with depressive symptoms. Although the association of social support with depressive symptoms was negligible, social support mediated associations of neighborhood quality with perceived stress [standardized path coefficient = .38 (.02), p = .009]. Our results point to the need for public health, health care, as well as non-health related interventions (e.g. crime prevention programs) to decrease overall exposure to stressors, as well as stress levels of women living in poor quality neighborhoods. Interventions that increase the levels of social support of women during pregnancy are also needed for their potential to decrease stress and ultimately improve mental health at this important time in the life course.

    The aim of this study is to compare the psychopathology and the quality of life of chronic daily headache patients between those with migraine headache and those with tension-type headache. We enrolled 106 adults with chronic daily headache (CDH) who consulted for the first time in specialised centres. The patients were classified according to the IHS 2004 criteria and the propositions of the Headache Classification Committee (2006) with a computed algorithm: 8 had chronic migraine (without medication overuse), 18 had chronic tension-type headache (without medication overuse), 80 had medication overuse headache and among them, 43 fulfilled the criteria for the sub-group of migraine (m) MOH, and 37 the subgroup for tension-type (tt) MOH. We tested five variables: MADRS global score, HAMA psychic and somatic sub-scales, SF-36 psychic, and somatic summary components. We compared patients with migraine symptoms (CM and mMOH) to those with tension-type symptoms (CTTH and ttMOH) and neutralised pain intensity with an ANCOVA which is a priori higher in the migraine group. We failed to find any difference between migraine and tension-type groups in the MADRS global score, the HAMA psychological sub-score and the SF36 physical component summary. The HAMA somatic anxiety subscale was higher in the migraine group than in the tension-type group (F(1,103) = 10.10, p = 0.001). The SF36 mental component summary was significantly worse in the migraine as compared with the tension-type subgroup (F(1,103) = 5.758, p = 0.018). In the four CDH subgroups, all the SF36 dimension scores except one (Physical Functioning) showed a more than 20 point difference from those seen in the adjusted historical controls. Furthermore, two sub-scores were significantly more affected in the migraine group as compared to the tension-type group, the physical health bodily pain (F(1,103) = 4.51, p = 0.036) and the mental health (F(1,103) = 8.17, p = 0.005).

    We extended Wilson and Cleary's (1995) health-related quality of life model to examine the relationships among symptoms status (Symptoms), functional health (Disability), and quality of life (QOL). Using a community sample (N = 956) of male HIV positive patients, we tested a mediation model in which the relationship between Symptoms and QOL is partially mediated by Disability. Common and unique ideas from three approaches to examining moderation of effects in mediational models (Edwards & Lambert, 2007; Preacher, Rucker, & Hayes, 2007; MacKinnon, 2008) were used to test whether (a) the direct relationship of Symptoms to QOL and (b) the relationship of Disability to QOL are moderated by age. In the mediation model, both the direct and the indirect (mediated) effects were significant. The direct relationship of Symptoms to QOL was significantly moderated by age, but the relationship of Disability to QOL was not. High Symptoms were associated with lower QOL at all ages, but that this relationship became stronger at older ages. We compare the three approaches and consider their advantages over traditional approaches to combining mediation and moderation. PMID:20706561

    It is unknown whether children with functional gastrointestinal disorders (FGIDs) identify specific foods that exacerbate their gastrointestinal (GI) symptoms. The objectives of this study were to determine the perceived role of food on GI symptoms and to determine the impact of food-induced symptoms on quality of life (QOL) in children with FGIDs. Between August and November 2010, 25 children ages 11–17 years old with FGIDs and a parent completed a food symptom association questionnaire and validated questionnaires assessing FGID symptoms and QOL. In addition, children completed a 24-hour food recall, participated in focus groups to identify problematic foods and any coping strategies, and discussed how their QOL was affected. Statistical analyses were conducted using chi-squared, t-testing, Mann-Whitney U, Wilcoxon signed-rank, and Spearman’s rho. Children identified a median of 11 (range 2–25) foods as exacerbating a GI symptom, with the most commonly identified foods being spicy foods, cow’s milk, and pizza. Several coping strategies were identified including consuming smaller portions, modifying foods, and avoiding a median of 8 (range 1–20) foods. Children reported that food-induced symptoms interfered with school performance, sports, and social activities. Although the parent’s assessment of their child’s QOL negatively correlated with the number of perceived symptom-inducing foods in their child, this relationship was not found in the children. Findings suggest that specific foods are perceived to exacerbate GI symptoms in children with FGIDs. Moreover, despite use of several coping strategies, food-induced symptoms may adversely impact children’s QOL in several important areas. PMID:24360501

    The study identified relations among traumatic stressors, HIV-related trauma symptoms, comorbid medical conditions, and health related quality of life (HRQL) in individuals with HIV. Participants (N = 118) completed a structured clinical interview on HIV as a traumatic stressor and other severe traumatic stressors and completed the Impact of Event Scale to assess HIV-related trauma symptoms and the Medical Outcomes Study 36-item Short Form (SF-36) to assess HRQL. Medical chart reviews determined comorbid conditions. Path analysis findings indicated participants with prior severe traumatic stressors experienced their HIV diagnosis as traumatic and in turn were more likely to have current HIV-related trauma symptoms which were negatively related to HRQL. HIV as a traumatic stressor was related to coronary artery diseases and HRQL. Traumatic stressors and HIV-related trauma symptoms impact health in individuals with HIV and highlight the need for psychological interventions prior to diagnosis and throughout treatment.

    Abstract Health-related quality of life (HRQOL) is an important clinical outcome for dialysis patients. However, relative superiority in HRQOL between automated peritoneal dialysis (APD) and continuous ambulatory peritoneal dialysis (CAPD) are not clearly known. We compared HRQOL over time between APD and CAPD patients and evaluated factors associated with HRQOL. All 260 incident patients initiating APD or CAPD at multiple centers throughout Korea were prospectively enrolled in this study between October 2010 and February 2013. HRQOL, depressive symptoms, and renal treatment satisfaction were assessed 1 and 12 months after the start of dialysis by the Kidney Disease Quality of Life Short Form 36 (KDQOL-36), the Beck Depression Inventory (BDI), and the Renal Treatment Satisfaction Questionnaire (RTSQ), respectively. Of 196 patients who completed all questionnaires and did not change the peritoneal dialysis (PD) modality during the 1-year follow-up period, 160 were matched. APD patients showed better baseline HRQOL than CAPD patients for the symptoms, patient satisfaction, pain, and social function domains. There were no differences in HRQOL between the 2 groups at 12 months, and CAPD patients had significantly greater improvements in symptoms (P = 0.02), the mental composite summary (P = 0.03), and health status domains (P = 0.03) than APD patients. There were similar improvements in depressive symptoms (P = 0.01) and patient satisfaction with treatment (P = 0.01) in CAPD and APD patients. Interestingly, depressive symptoms, not PD modality, was the most influential and consistent factor for HRQOL. Despite the spontaneous improvement of depressive symptoms, considerable PD patients still had depressive symptoms at the 1-year appointment. APD has no advantage over CAPD for HRQOL. Considering the substantial negative effect of depressive symptoms on HRQOL, it is important to evaluate PD patients for depression and to treat those with depression to

    Using the method of four-wave probing of the waist of the laser beam focused into the bulk of a short active medium (L ll τc, where L is the length of the active medium, τ is the pulse duration, and c is the speed of light), we have studied the dynamics of the behaviour of a dark soliton, appearing upon a jump of the input Stokes signal phase by about π under SBS. The computer simulation has shown that when spontaneous noises with the gain increment Γ, exceeding the self-reflection threshold by 2 - 3 times, are generated, the dark soliton propagates along the interaction region for the time t ≈ T2Γth/2, where T2 is the the lifetime of acoustic phonons, and Γth = 25 - 30 is the stationary threshold gain increment.

    There are few studies on sick building syndrome (SBS) including clinical measurements for atopy and fractional exhaled nitric oxide (FeNO). Our aim was to study associations between SBS symptoms, selected personal factors, office characteristics and indoor office exposures among office workers from a university in Malaysia. Health data were collected by a questionnaire (n=695), skin prick test (SPT) (n=463) and FeNO test (n=460). Office settled dust was vacuumed and analyzed for endotoxin, (1,3)-β-glucan and house dust mites (HDM) allergens group 1 namely Dermatophagoides pteronyssinus (Der p 1) and Dermatophagoides farinae (Der f 1). Office indoor temperature, relative air humidity (RH), carbon monoxide (CO) and carbon dioxide (CO2) were measured by a direct reading instrument. Associations were studied by two-levels multiple logistic regression with mutual adjustment and stratified analysis. The prevalence of weekly dermal, mucosal and general symptoms was 11.9%, 16.0% and 23.0% respectively. A combination of SPT positivity (allergy to HDM or cat) and high FeNO level (≥25 ppb) was associated with dermal (p=0.002), mucosal (p<0.001) and general symptoms (p=0.05). Der f1 level in dust was associated with dermal (p<0.001), mucosal (p<0.001) and general (p=0.02) symptoms. Among those with allergy to D. farinae, associations were found between Der f 1 levels in dust and dermal (p=0.003), mucosal (p=0.001) and general symptoms (p=0.007). Office-related symptoms were associated with Der f 1 levels in dust (p=0.02), low relative air humidity (p=0.04) and high office temperature (p=0.05). In conclusion, a combination of allergy to cat or HDM and high FeNO is a risk factor for SBS symptoms. Der f 1 allergen in dust can be a risk factor for SBS in the office environment, particularly among those sensitized to Der f 1 allergen. PMID:26225741

    Introduction In today’s world of economic crisis it is not feasible for an orthodontist to replace each and every debonded bracket with a new bracket- quest for an alternative thrives Orthodontist. The concept of recycling bracket for its reuse has evolved over a period of time. Orthodontist can send the brackets to various commercial recycling companies for recycling, but it’s impractical as these are complex procedures and require time and usage of a new bracket would seem more feasible. Thereby, in-house methods have been developed. The aim of the study was to determine the SBS (Shear Bond Strength) and to compare, evaluate the efficiency of in house recycling methods with that of the SBS of new brackets. Materials and Methods Five in–house-recycling procedures-Adhesive Grinding Method, Sandblasting Method, Thermal Flaming Method, Buchman method and Acid Bath Method were used in the present study. Initial part of the study included the use of UV/Vis spectrophotometer where in the absorption level of base of new stainless steel bracket is compared with the base of a recycled bracket. The difference seen in the UV absorbance can be attributed to the presence of adhesive remnant. For each recycling procedure the difference in UV absorption is calculated. New stainless steel brackets and recycled brackets were tested for its shear bond strength with Instron testing machine. Comparisons were made between shear bond strength of new brackets with that of recycled brackets. The last part of the study involved correlating the findings of UV/Vis spectrophotometer with the shear bond strength for each recycling procedure. Results Among the recycled brackets the Sandblasting technique showed the highest shear bond strength (19.789MPa) and the least was shown by the Adhesive Grinding method (13.809MPa). Conclusion The study concludes that sand blasting can be an effective choice among the 5 in house methods of recycling methods. PMID:26501002

    Transthyretin familial amyloid polyneuropathy (TTR-FAP) is an inherited amyloidosis, leading to death in about ten years in most cases due to cardiac failure or wasting syndrome. Previous studies showed that modified body mass index was related to time before death, duration of gastrointestinal disturbances, malabsorption and functional capacity. We report two patients in whom nutritional status worsened despite diet modification, hypercaloric supplement and two relevant therapeutic approaches such as liver transplant and tafamidis meglumine, respectively. The first patient, a 52-year-old lady carrying Thr49Ala mutation, had a disease duration of twelve years and had lost weight up to 35 kg because of daily diarrhea. The second patient, a 63-year-old man with Glu89Gln mutation and a disease duration of fifteen years, was in the New York Heart Association (NYHA) Functional Classification class III and his weight was 39 kg. In both cases, a peripherally inserted central catheter was placed for parenteral nutrition. It allowed to improve their nutritional status and clinical conditions, with body weight gains of 11 and 8 kg in a one year follow-up, respectively. Moreover, reduction of autonomic symptoms including postural hypotension, nausea and diarrhoea was recorded with ameliorated quality of life. Our experience suggests that parenteral nutrition may be useful in reducing complications and disabilities in TTR-FAP patients, even when all dietary adjustments have been ineffective. Reasonably, the improvement in nutritional status may prolong survival in TTR-FAP patients. PMID:27132122

    Depression, common in chronic medical conditions, and hepatic encephalopathy (HE), a reversible neuropsychiatric syndrome due to liver dysfunction, are associated with impaired health-related quality of life (HRQOL) in cirrhosis and hepatitis C (HCV). This study investigated the impact of depression and HE on HRQOL in cirrhotic patients with HCV. A convenience sample of 43 ambulatory patients, with varying degrees of cirrhosis secondary to HCV, was prospectively enrolled in this study. Participants were assessed for any current depressive, fatigue, and daytime sleepiness symptoms and underwent a psychometric evaluation to determine the presence of HE symptoms. Participants reported current HRQOL on general health and liver disease-specific questionnaires. Diagnosis and current health status were confirmed via medical records. The associations between disease severity, depressive symptoms, HE, fatigue, and daytime sleepiness were measured. Predictors of HRQOL in this sample were determined. Depressive symptoms (70 %) and HE (77 %) were highly prevalent in this sample, with 58 % actively experiencing both conditions at the time of study participation. A significant positive association was found between depressive symptoms and HE severity (P = .05). Depressive symptoms were significantly associated with fatigue (P < .001), daytime sleepiness (P < .001), general HRQOL (P < .001), and disease-specific HRQOL (P < .001). HE was significantly associated with fatigue (P = .02), general HRQOL (P < .001), and disease-specific HRQOL (P < .001). Depressive symptoms and HE were significant predictors of reduced HRQOL (P < .001), with depressive symptoms alone accounting for 58.8 % of the variance. Depressive symptoms and HE accounted for 68.0 % of the variance. Findings suggest a possible pathophysiological link between depression and HE in cirrhosis, and potentially a wider-reaching benefit of treating minimal and overt HE than previously appreciated

    Background Dyspepsia and headache frequently co-exist, but the clinical implication of this association is uncertain. We planned to examine the prevalence and impact of dyspepsia in adults with headache. Methods A cross-sectional study was conducted in a secondary care setting. Clinical, psychological and health-related quality of life (HRQOL) data were compared between subjects with headache and controls (non-headache subjects). The impact of dyspepsia was analysed further in subjects with headache alone. Results 280 subjects (93 cases with headache and 187 matched controls) were recruited. The following baseline characteristics of subjects were as follows: mean age 45.0±17.3 years, 57.0% females and ethnic distribution—Malaysian = 45 (48.4%), Chinese n = 24 (25.8%) and Indians n = 24 (25.8%). Headache sub-types among cases with headache were as follows: tension-type headache (TTH) n = 53 (57.0%) and migraine n = 40 (43.0%). Dyspepsia was more prevalent in cases with headache compared to controls (25.8% vs 12.8%, p = 0.011), and headache was independently associated with dyspepsia (OR 2.75, 95% CI 1.39–5.43). Among cases with headache, there was a trend towards a higher prevalence of dyspepsia in those with migraine (27.5%) compared to TTH (24.5%). Subjects with headache and dyspepsia, compared to those with headache alone, had a greater severity of headache symptoms (63.67±22.85 mm vs 51.20 ±24.0 mm VAS, p = 0.029). Overall HRQOL scores were lower in headache subjects with dyspepsia (EQ-5D summary score 0.82±0.18 vs 0.90 ±0.16, p = 0.037 and EQ-5D VAS 62.08±17.50 mm vs 72.62 ±18.85 mm, p = 0.018), compared to those without dyspepsia. Conclusion Dyspepsia is associated with more severe headache symptoms and results in a lower HRQOL in patients with headache. PMID:25629323

    Background. Anxiety and panic are known to be associated with bronchial asthma with variety of impact on clinical presentation, treatment outcome, comorbidities, quality of life, and functional disability in patients with asthma. This study aims to explore the pattern of panic symptoms, prevalence and severity of panic disorder (PD), quality of life, and disability in them. Methods. Sixty consecutive patients of bronchial asthma were interviewed using semistructured proforma, Panic and Agoraphobia scale, WHO Quality of life (QOL) BREF scale, and WHO disability schedule II (WHODAS II). Results. Though 60% of the participants had panic symptoms, only 46.7% had diagnosable panic attacks according to DSM IV TR diagnostic criteria and 33.3% had PD. Most common symptoms were "sensations of shortness of breath or smothering," "feeling of choking," and "fear of dying" found in 83.3% of the participants. 73.3% of the participants had poor quality of life which was most impaired in physical and environmental domains. 55% of the participants had disability score more than a mean (18.1). Conclusion. One-third of the participants had panic disorder with significant effect on physical and environmental domains of quality of life. Patients with more severe PD and bronchial asthma had more disability. PMID:26425540

    This pilot study examined the effects of Reiki therapy and companionship on improvements in quality of life, mood, and symptom distress during chemotherapy. Thirty-six breast cancer patients received usual care, Reiki, or a companion during chemotherapy. First, data were collected from patients receiving usual care. Second, patients were randomized to either receive Reiki or a companion during chemotherapy. Questionnaires assessing quality of life, mood, symptom distress, and Reiki acceptability were completed at baseline and chemotherapy sessions 1, 2, and 4. Reiki was rated relaxing with no side effects. Reiki and companion groups reported improvements in quality of life and mood that were greater than those seen in the usual care group. Interventions during chemotherapy, such as Reiki or companionship, are feasible, acceptable, and may reduce side effects. PMID:25381189

    Solvent-cast films of styrene-butadiene-styrene triblock copolymer (SBS) were synthesized and a poly(2-hydroxyethyl methacrylate) (PHEMA) layer was grafted onto these films using Co 60 gamma-ray irradiation. The IR absorption spectrum of the graft copolymer was taken and its surface morphology studied by a scanning electron microscope. The degree of grafting and the mechanical properties of SBS, SBS-g-HEMA, and PHEMA were measured. In order to study its biocompatibility, contact angle and blood clotting time experiments were performed. The degree of grafting was related to the soaking time, film thickness and total irradiation dosage. However, it levelled off at 7% when the total dosage reached 1 Mrad. It was found that the mechanical properties of SBS-g-HEMA were the same as those of SBS and were superior to those of PHEMA. The blood compatibility of SBS-g-HEMA as measured by the Lee-White clotting test was better than that of SBS and polystyrene and was quite similar to that of PHEMA. PMID:3397379

    Background & Aims Little is known about long-term health outcomes of children with dyspeptic symptoms. We studied the natural history of pediatric patients with dyspeptic symptoms, with and without histologic reflux, compared to healthy controls. Methods We performed a prospective study of consecutive new patients, ages 8–16 years, who underwent evaluation for dyspepsia, including upper endoscopy. Patients were assigned to groups with histologic evidence of reflux esophagitis (n=50), or normal histology results (n=53). Healthy children were followed as controls (n=143). Patients and controls were evaluated 5–15 years later. They provided self reports on severity of dyspeptic symptoms, use of acid suppression, quality of life, anxiety, and depression. Results When the study began, the groups with histologic evidence for esophagitis and normal histologies did not differ in severity of dyspeptic symptoms, functional disability, or depression. After a mean 7.6-year follow-up period, each group had significantly lower quality of life scores and more severe dyspeptic symptoms and functional disability than controls, but did not differ significantly from each other; both groups were significantly more likely than controls to meet criteria for an anxiety disorder. At time of follow-up, use of acid suppression medication was significantly greater in the group with histologic evidence for esophagitis, compared with patients that had normal histology findings when the study began. Conclusion Among pediatric patients with dyspepsia evaluated by endoscopy and biopsy, those with histologic evidence for esophagitis or normal histology findings are at increased risk for chronic dyspeptic symptoms, anxiety disorder, and reduced quality of life in adolescence and young adulthood.

    Evidence indicates exercise is beneficial for motor and non-motor function in older adults and people with chronic diseases including Parkinson disease (PD). Dance may be a relevant form of exercise in PD and older adults due to social factors and accessibility. People with PD experience motor and non-motor symptoms, but treatments, interventions, and assessments often focus more on motor symptoms. Similar non-motor symptoms also occur in older adults. While it is well-known that dance may improve motor outcomes, it is less clear how dance affects non-motor symptoms. This review aims to describe the effects of dance interventions on non-motor symptoms in older adults and PD, highlights limitations of the literature, and identifies opportunities for future research. Overall, intervention parameters, study designs, and outcome measures differ widely, limiting comparisons across studies. Results are mixed in both populations, but evidence supports the potential for dance to improve mood, cognition, and quality of life in PD and healthy older adults. Participation and non-motor symptoms like sleep disturbances, pain, and fatigue have not been measured in older adults. Additional well-designed studies comparing dance and exercise interventions are needed to clarify the effects of dance on non-motor function and establish recommendations for these populations.

    Background Non-motor symptoms, quality of life, service needs, and barriers to care of individuals with movement disorders are not well explored. This study assessed these domains within a sample of individuals with essential tremor (ET) and Parkinson's disease (PD). Methods A survey exploring symptoms, needs, and barriers to care was disseminated to a convenience sample (N = 96) of individuals with a primary diagnosis of ET (N = 19) or PD (N = 77). Results Similarities in overall quality of life and impact on daily functioning were found across individuals with ET and PD. Noteworthy differences included endorsement of different types of service needs and utilization patterns and fewer non-motor symptoms reported among those with ET (M = 6.1, SD = 2.4) than those with PD (M = 10.4, SD = 3.4). Non-motor symptoms significantly impacted movement disorder-related quality of life for both diagnostic groups, but this relationship was stronger for individuals with ET, t(12) = 3.69, p = 0.003, β = 0.73 than with PD, t(56) = 4.00, p<0.001, β = 0.47. Individuals with ET also reported higher rates of stigma (31.6% vs. 7.8%) and greater impact of non-motor symptoms on emotional well-being, R2 = 0.37, F(1, 13) = 7.17, p = 0.020. Discussion This is the first study to describe and compare the needs, barriers to care, and impact on quality of life of two distinct movement disorder groups. Our results support the recent efforts of the field to identify interventions to address the non-motor symptoms of movement disorders and indicate need for greater appreciation of the specific differences in symptoms and quality of life experienced across movement disorder diagnoses.

    We present high-quality spectroscopic observations of the two most metal-deficient blue compact galaxies known, I Zw 18 and SBS 0335-052. We use the data to determine the heavy-element and helium abundances. The oxygen abundances in the northwest and the southeast components of I Zw 18 are found to be the same within the errors, 7.17+/-0.03 and 7.18+/-0.03, respectively, although marginally statistically significant spatial variations of oxygen abundance might be present. In contrast, we find a statistically significant gradient of oxygen abundance in SBS 0335-052. The largest oxygen abundance, 12+logO/H=7.338+/-0.012, is found in the region 0.6" to the northeast of the brightest part of the galaxy, and it decreases toward the southwest to values of ~7.2, comparable to that in I Zw 18. The underlying stellar absorption strongly influences the observed intensities of He I emission lines in the brightest northwest component of I Zw 18, and hence this component should not be used for primordial He abundance determination. The effect of underlying stellar absorption, though present, is much smaller in the southeast component. Assuming all systematic uncertainties are negligible, the He mass fraction Y=0.243+/-0.007 derived in this component is in excellent agreement with recent measurements by Izotov & Thuan, suggesting the robustness of the technique applied in measurements of the helium abundance in low-metallicity blue compact galaxies. The high signal-to-noise ratio spectrum (>=100 in the continuum) of SBS 0335-052 allows us to measure the helium mass fraction with a precision better than 2%-5% in nine different regions along the slit. We show that, while underlying stellar absorption in SBS 0335-052 is important only for the He I 4471 Å emission line, other mechanisms such as collisional and fluorescent enhancements are influencing the intensities of all He I emission lines and should be properly taken into account.

    This study investigated whether sick building syndrome (SBS) complaints among office workers were associated with the indoor air quality. With informed consent, 417 employees in 87 office rooms of eight high-rise buildings completed a self-reported questionnaire for symptoms experienced at work during the past month. Carbon dioxide (CO2), temperature, humidity and total volatile organic compounds (TVOCs) in each office were simultaneously measured for eight office hours using portable monitors. Time-averaged workday difference between the indoor and the outdoor CO2 concentrations (dCO2) was calculated as a surrogate measure of ventilation efficiency for each office unit. The prevalence rates of SBS were 22.5% for eye syndrome, 15.3% for upper respiratory and 25.4% for non-specific syndromes. Tiredness (20.9%), difficulty in concentrating (14.6%), eye dryness (18.7%) were also common complaints. The generalized estimating equations multivariate logistic regression analyses showed that adjusted odds ratios (aORs) and 95% confidence interval (CI) per 100 ppm increase in dCO2 were significantly associated with dry throat (1.10, 95% CI=(1.00-1.22)), tiredness (1.16, 95% CI=(1.04-1.29)) and dizziness (1.22, 95% CI=(1.08-1.37)). The ORs for per 100 ppb increases in TVOCs were also associated with upper respiratory symptoms (1.06, 95% CI=(1.04-1.07)), dry throat (1.06, 95% CI=(1.03-1.09)) and irritability (1.02, 95% CI=(1.01-1.04)). In conclusion, the association between some SBS symptoms and the exposure to CO2 and total VOCs are moderate but may be independently significant. PMID:26024357

    Studies concerning persons living with HIV (PLWH) report that stressful life events (SLE) contribute to an exacerbation of symptoms and reduced antiretroviral (ARV) adherence and quality of life (QOL). Little is known about whether these findings are site-specific. Our study's aims were to characterize the type and frequency of SLE for PLWH in Puerto Rico, South Africa, and the United States and to assess the impact of SLE by national site, symptoms, and ARV adherence concerns on QOL. The sample consisted of 704 participants. The total number of SLE correlated significantly with the total number of symptoms, adherence concerns, and QOL (p ≤ .001). Overall, 27.2% of the variance in QOL was explained by the aforementioned variables. Although SLE were of concern to PLWH, worries about ARV adherence were of even greater concern. Routine assessment of ARV concerns and SLE can promote ongoing ARV adherence and improved QOL. PMID:23473660

    It is known that the main criterion for the selection of active objects in the First Byurakan, otherwise Markarian survey was the presence of signs of UV-excess in their low-dispersion spectra. Using the presence of emission lines as the second criteria became real during the Second Byurakan survey because of its improved technique. Extended (not stellated) objects, selected with the use of this criterion, made the main part of the separate sample of SBS galaxies. Originally, this sample included 1286 objects, selected in 65 fields of the survey (16 square degree each), to which, with the help of other sources than the survey, there were later added some objects. We studied a subsample of SBS galaxies in seven selected fields (the deepest according to the V/Vmax criterion), including about the third of the whole sample. The first, already completed phase of this program was started with carrying out a follow-up slit spectroscopy of all, about 500 objects, based on observations with long-slit spectrographs with 6m telescope of SAO Russia and 2.6.m telescope of Byurakan. As a result redshifts were determined, as well as spectral classification was made for all of objects, using the scheme adapted to the spectral material. Besides other, obtained data allowed us to estimate the efficiency of used criteria for the selection of galaxies of different classes of starformation and nuclear activity along the full scale of the apparent magnitudes, including close to the limit values (18.5 < m pg < 19.5), etc. The fact that the total area of seven fields as the total number of objects in them comparable with these values for the survey as a whole, allows us to extrapolate the results to the whole sample of galaxies as an upper estimate. The second stage is to conduct detailed studies of individual galaxies in the first place, the most interesting in terms of morphology. They are based on panoramic spectroscopy obtained from observations at 6 m telescope of Russia and 2.6m

    Definition Menopause begins one year after the last menstrual period. Symptoms often begin in the perimenopausal years. Incidence/prevalence In the United Kingdom the mean age for the menopause is 50 years 9 months. The median onset of the perimenopause is between 45.5 and 47.5 years. One Scottish survey (of 6096 women aged 45 to 54 years) found that 84% had experienced at least one of the classic menopausal symptoms, with 45% finding one or more symptoms a problem.1 InterventionsBeneficial:OestrogensTiboloneLikely to be beneficial:ProgestogensClonidineUnknown effectiveness:Phyto-oestrogensTestosteroneAntidepressants Aetiology/risk factors Urogenital symptoms of menopause are caused by decreased oestrogen concentrations, but the cause of vasomotor symptoms and psychological effects is complex and remains unclear. Prognosis Menopause is a physiological event. Its timing may be genetically determined. Although endocrine changes are permanent, menopausal symptoms such as hot flushes, which are experienced by about 70% of women, usually resolve with time.2 However, some symptoms, such as genital atrophy, may remain the same or worsen.

    As the key of these all optical techniques which would be widely used in the future optical fiber communication, the stimulated Brillouin scattering (SBS) slow light draws a great of attention and shows several advantages over other slow light methods. With recent growth of nano-technology, researchers are hoping to improve the nonlinearity of the optical fiber by using the nano-technology. According to this current situation, a numerical model of the SBS slow light and three typical experiments are discussed. A novel optical fiber doped with nano material as InP is manufactured and introduced into the SBS slow light, serving as the nonlinear medium of SBS process. And the numerical simulations are performed to validate our method. The results show a considerable time delay of the optical light can be achieved through this novel optical fiber.

  15. A Theoretical and Experimental Analysis of SBS Suppression Through Modification of Amplifier Seed

    2011-12-01

    Theoretical and experimental investigations of stimulated Brillouin scattering (SBS) are conducted in Yb-doped fiber amplifiers when the amplifier is simultaneously seeded with multiple distinct frequencies or with a phase modulated signal. To this end, detailed models of the SBS process are developed consisting of both a steady-state approach described mathematically by a coupled set of ordinary differential equations and also transient effects described by a coupled set of partial differential equations. For the multi-frequency seeded case, the equations are solved in the steady-state limit and include the effects of four-wave mixing (FWM), intrinsic and external thermal gradients, and laser gain. In one configuration of the multi-seeded case, the signals are separated at twice the acoustic frequency of the fiber medium in order to create nonlinear Brillouin gain coupling between the seeds and Stokes signals, which suppresses the SBS process in the highest frequency seed. The concept is theoretically investigated for the two and three seeded cases. It is shown that for this scheme, FWM becomes quite significant making this concept unlikely in a practical application requiring single-frequency output. Alternatively, a novel concept is developed to suppress SBS in fiber amplifiers that relies on laser gain competition among multiple seeds to create both a favorable thermal gradient and a reduced effective length for the SBS process. In one configuration, the amplifier is simultaneously seeded with a broadband (Deltalambda˜ 0.1nm) and single-frequency Delta v ˜100kHz seed. In this case, several experiments are performed to validate the theoretical predictions with experiments leading to a 203 W polarization maintaining (PM), co-pumped monolithic fiber amplifier demonstration. To the best of our knowledge, this output power is the highest reported in the literature to date for such an amplifier. A time-dependent model of the SBS process initiated from random

    Aim and Objective: To analyze the menopause-related symptoms and its impact on quality of life in post-menopausal women from urban and rural area. Materials and Methods: A cross-sectional 1-year study was carried among women of urban (n = 490) and rural (n = 380) areas, attending the outpatient department in the urban area and a house-to-house survey in rural areas, by interviews with the help of a pretested semi-structured standard questionnaire. For assessment of the menopausal symptoms menopause rating scale (MRS) and for quality of life, World Health Organization Quality of Life Scale (WHO QOL-BREF) questionnaire was used. Results: There was a significant difference between the MRS total scores of the urban (14.67 ± 6.64) and rural (16.08 ± 7.65) group. The somatic, psychological, and urogenital symptoms were high in rural women than in urban women. The results were not significant for urogenital subscale. The mean raw scores of physical health, psychological, social relationships, and environmental domains was more in urban than in rural women. The mean transformed scores (4-20) of physical health, psychological, social relationships, and environmental domains was more in urban than in rural women. The mean transformed scores (0-100) including the physical health, psychological, social relationships, and environmental domains was more in urban than in rural women. The result was not significant for physical health. Conclusion: The high proportions and the scores of MRS were observed in both rural and the urban women. The severity of symptoms was found more distressing for rural women. The quality of life in urban society was average and better than in rural women. PMID:25861203

    This randomized, placebo-controlled, double-blind study compared the effects of daily supplementation for 4 week with 250 mg Wellmune WGP® β-1,3/1,6-Glucan (WGP) with placebo 250 mg/day (rice flour) on physical and psychological health attributes of self-described “moderate” ragweed allergy sufferers. Study participants (mean age = 36 ± 9 year; range 18–53 year) were recruited before the beginning of ragweed season (September) in Northeastern Ohio. Serum IgE concentration, allergy symptoms [via self-report, Visual Analog Scale (VAS), and Rhinoconjunctivitis Quality of Life Questionnaire (RQLQ)], psychological well-being [Profile of Mood States (POMS)], and physical function (RAND SF-36 Medical Outcomes Study) were measured immediately prior to and after supplementation with WGP (n = 24) or placebo (n = 24) for 4 weeks. Data were analyzed using repeated measures analyses of variance (ANOVA). Compared with placebo, WGP reduced total allergy symptoms (28%), symptom severity (52%), and symptom rating on the VAS (37%) (P < 0.05), but had no effect on serum IgE levels. As measured by the POMS, WGP increased participants' rating of vigor (10%), but reduced tension (34%), depression (45%), anger (41%), fatigue (38%), and confusion (34%) (P < 0.05). Study participants given WGP reported increased physical health (11%), energy (19%), and emotional well-being (7%) compared with study participants given the placebo (RAND SF-36 Medical Outcomes Study). The WGP group also reported decreased sleep problems (53%), reduced nasal symptoms (59%), eye symptoms (57%), non-nasal symptoms (50%), activities (53%), emotions (57%), and improved quality of life (QOL) (56%), as well as improved global mood state (13%). Supplementation with WGP for 4 weeks improved allergy symptoms, overall physical health, and emotional well-being compared with placebo in self-described “moderate” ragweed allergy sufferers during ragweed allergy season.

    Background Children in urban public housing are at high risk for asthma, given elevated environmental and social exposures and suboptimal medical care. For a multifactorial disease like asthma, design of intervention studies can be influenced by the relative prevalence of key risk factors. To better understand risk factors for asthma morbidity in the context of an environmental intervention study, we conducted a detailed baseline evaluation of 78 children (aged 4–17 years) from three public housing developments in Boston. Methods Asthmatic children and their caregivers were recruited between April 2002 and January 2003. We conducted intake interviews that captured a detailed family and medical history, including questions regarding asthma symptom severity, access to health care, medication usage, and psychological stress. Quality of life was evaluated for both the child and caregiver with an asthma-specific scale. Pulmonary function was measured with a portable spirometer, and allergy testing for common indoor and outdoor allergens was conducted with skin testing using the prick puncture method. Exploratory linear and logistic regression models evaluating predictors of respiratory symptoms, quality of life, and pulmonary function were conducted using SAS. Results We found high rates of obesity (56%) and allergies to indoor contaminants such as cockroaches (59%) and dust mites (59%). Only 36% of children with persistent asthma reported being prescribed any daily controller medication, and most did not have an asthma action plan or a peak flow meter. One-time lung function measures were poorly correlated with respiratory symptoms or quality of life, which were significantly correlated with each other. In multivariate regression models, household size, body mass index, and environmental tobacco smoke exposure were positively associated with respiratory symptom severity (p < 0.10). Symptom severity was negatively associated with asthma-related quality of life for the

    Objective This study investigated the mediating effects of the internal psychological factors of self-esteem and optimism on the relationship between breast cancer patients' quality of life in terms of symptoms and functioning and depressive symptoms. Methods The study centered on 384 breast cancer patients who had within a 24-month period received diagnosis of 0-4 stage cancer and had medical treatment. To achieve the study's purpose, the study made use of EORTC QLQ BR23, CES-D, and the Self-Esteem and Optimism Scales. Results Findings revealed that breast cancer patients' quality of life was negatively impacted by self-esteem and optimism, and that self-esteem and optimism impacted negatively on depressive symptoms. Analyses showed that when breast cancer patients' quality of life affects depressive symptoms, the full mediation effect of self-esteem was statistically significant. Also, findings revealed there to be a significant partial mediation effect due to optimism. Conclusion Study findings demonstrated that enhancing self-esteem is crucial in the psychological intervention of depressive symptoms because self-esteem functioned as the main causal factor accounting for all variation when breast cancer patients' quality of life affected depressive symptoms. In addition, results suggested that optimism is also vital to psychological intervention because it functioned as partial cause of heightened depressive symptoms when breast cancer patients' quality of life affected depressive symptoms.

    Loud speaking due to noisy working conditions is a common cause for teachers' voice disorders. One way to diminish the vocal load of teaching is to make use of technical equipment. This Icelandic study explores: (1) if the use of amplification in classrooms would diminish the teachers' experienced symptoms of vocal fatigue; and (2) whether there is a possible change in perceptual voice quality during a teachers' working day. Thirty-three teachers, from grade school to university level, voluntarily served as subjects. They used amplifiers while teaching for one week at least. After that, they filled out a questionnaire concerning their symptoms and experiences. The results showed that the majority of teachers found amplification beneficial. They found it easier to talk and experienced less fatigue. The few disadvantages were technical. For a perceptual analysis, three females and two males (mean age 51 years) with long teaching experience and three or more dysphonic symptoms during the term, had their speech recorded while teaching, with and without amplification. In the clinical examination, no pathological changes were found in the vocal folds. In both studies, the quality of the voices was esteemed better when amplification was used.

    Diet is important in triggering the symptoms of irritable bowel syndrome (IBS). This study investigated the impact of dietary guidance on the symptoms, quality of life and habitual diet of patients with IBS. Forty-six patients who fulfilled the Rome III criteria for the diagnosis of IBS were included. Of these patients, 17 completed the entire study. Each patient attended three sessions (~45 min in duration) and received individual guidance on their dietary management. The patients were asked to complete the following questionnaires prior to receiving the dietary guidance, and at least 3 months subsequently: The Birmingham IBS symptom score questionnaire, the IBS Quality of Life (IBS-QOL) questionnaire, the Short-Form Nepean and Dyspepsia Index (SF‑NDI) and the MoBa Food Frequency Questionnaire (MoBa FFQ). The time at which patients completed the questionnaires following dietary guidance ranged from 3-9 months (median, 4 months). The total IBS symptom scores were reduced once the patients had received dietary guidance (P=0.001). The total score for the quality of life, as assessed by the IBS‑QOL and the SF-NDI, increased significantly following the dietary guidance sessions (P=0.003 and P=0.002, respectively). There were no statistical differences in the intake of calories, carbohydrate, fiber, protein, fat or alcohol in the patients with IBS following dietary guidance. There were increases in the consumption of dairy products, β-carotene, retinol equivalents, riboflavin, vitamin B12 and calcium, although only the increase in vitamin B12 consumption was statistically significant. There was a significant reduction in the consumption of certain fruits and vegetables that were rich in highly fermentable short-chain carbohydrates, disaccharides, monosaccharides and polyols, as well as insoluble fibers. In conclusion, three 45-min dietary guidance sessions, administered by a nurse, reduced the symptoms and improved the quality of life of patients with IBS, and

    Building Health Sciences, Inc. (BHS), investigated environmental conditions by many modalities in 71 discreet areas of 12 buildings in a government building complex that had experienced persistent occupant complaints despite correction of deficiencies following a prior survey. An online health survey was completed by 7,637 building occupants (49% response rate), a subset of whom voluntarily wore personal sampling apparatus and underwent medical evaluation. Building environmental measures were within current standards and guidelines, with few outliers. Four environmental factors were consistently associated with group-level building-related health complaints: physical comfort/discomfort, odor, job stress, and glare. Several other factors were frequently commented on by participants, including cleanliness, renovation and construction activities, and noise. Low relative humidity was significantly associated with lower respiratory and "sick building syndrome"-type symptoms. No other environmental conditions (including formaldehyde, PM10 [particulate matter with an aerodynamic diameter <10 μm], or mold levels, which were tested by 7 parameters) correlated directly with individual health symptoms. Indicators of atopy or allergy (sinusitis, allergies, and asthma), when present singly, in combinations of 2 conditions, or together, were hierarchically associated with the following: increased absence, increased presenteeism (presence at work but at reduced capacity), and increase in reported symptom-days, including symptoms not related to respiratory disease. We found that in buildings without unusual hazards and with environmental and air quality indicators within the range of acceptable indoor air quality standards, there is an identifiable population of occupants with a high prevalence of asthma and allergic disease who disproportionately report discomfort and lost productivity due to symptoms and that in "normal" buildings these outcome indicators are more closely

    The objective of this study is to assess how the non-motor symptoms of Parkinson's disease (PD), such as depression, cognitive deterioration, neuropsychiatric and sleep disorders, affect the quality of life, and to compare them with the motor symptoms in order to determine their real impact. A cross-sectional study was designed including 99 patients (mean age 68.5 ± 9.9 years, duration of disease 8.7 ± 6.2 years). Demographic data, onset of PD, years on treatment with levodopa (LD), class of dopaminergic drug prescribed, and dosages were obtained. The following scales were used: quality of life (PDQ-39), Unified Parkinson's Disease Rating Scale (UPDRS I-IV), Parkinson Disease Sleep Scale (PDSS) and daytime sleepiness (Epworth), Mini-Mental State Examination, depression (HAM-D), and the neuropsychiatric inventory (NPI-10). The PDQ-39 summary index (PDQ-39 SI) was 24.7 ± 13.2. A linear regression model including all variables showed that four independent variables accounted for 67.2% of the variance in the PDQ-39 SI (F = 33,277; p < 0.001): NPI, PDSS, UPDRS IV, and UPDRS I. When sub-items of the NPI, PDSS and UPDRS IV scales are analyzed, significant correlations (p < 0.001) are found between the PDQ-39 SI and depression, agitation, apathy, anxiety, hallucinations, delusions, incontinence of urine, morning painful posturing, restlessness in bed, morning fatigue, duration of off periods, unpredictable and predictable off periods, early morning dystonia, and sudden off periods. Neuropsychiatric symptoms, especially depression, nighttime sleep disorders such as urinary incontinence, nighttime restlessness, morning fatigue and somnolence, off-period dystonia and motor fluctuations are the variables that most affect the quality of life of patients with PD.

    Copper thioantimonates have received enormous attention due to their potential for applications in photovoltaic devices. In this work, a new layered compound KCu2SbS3 was synthesized via a reactive flux method using thiourea as a reactive flux. The compound crystallizes in the triclinic space group P1[combining macron]. The structure features two-dimensional [Cu2SbS3](-) layers stacking along the c axis with K(+) ions intercalated between the layers. Each [Cu2SbS3](-) layer is composed of two single graphene-like layers connected via interlayer Cu-S bonds and CuSb contacts. The optical measurements indicate that the compound has a band gap of 1.7 eV. The Hall effect measurement shows that KCu2SbS3 is a p-type semiconductor with a carrier concentration of 7 × 10(16) cm(-3). First-principles calculations reveal that the direct transition occurs between Cu-3d-S-3p orbitals (VBM) to Sb-5p-S-3p orbitals (CBM). The photoelectric response properties of KCu2SbS3 under visible light irradiation were analyzed. The photocurrent is 3.7 μA cm(-2) at 10 V bias, demonstrating its potential for applications in photoelectric devices. PMID:26794832

    Interaction of GHz and MHz radiation with CO2 laser propagation in a silver halide fiber using sBs based phonon coupling is furthet investigated. The external signal serves to both probe and enhance laser generated sBs phonons in the fiber. Efficient coupling of microwave radiation into the fiber is accomplished by placing the fiber in a hollow metallic waveguide, designed and constructed to transmit the dominant mode in the 0.9-2.0 GHz band. MHz radiation is conveniently coupled into the fiber using the guided microwave radiation as carrier. Phonon emissions from the fiber under CO2 laser pumping are first established on a spectrum analyzer; low frequency generators ale then tuned to match these frequencies and their maximum interaction recorded. Such interactions are systematically studied by monitoring the amplitude and waveform of the reflected and transmitted laser pulse at various power levels and frequencies of the externally coupled radiation. A plot of reflected laser power versus incident laser power reveals a distinct sBs generated phonon threshold. Variouslaunch directions of the GHz and MHz radiation with respect to the direction of laser propagation are realized to verify theory governing sBs interactions. The MHz radiation and its associated phonons in the fiber are convenient tools for probing sBs related phenomenon in infrared fibers.

    Background. Treating functional gastrointestinal disorders is extremely difficult. We herein report the effect of the oral administration of Ninjinto (NJT, ginseng decoction), a traditional Japanese Kampo medicine, on chronic intestinal failure. Patients and Methods. Seven patients with chronic intestinal failure treated with NJT were evaluated in this study. The primary diseases included chronic intestinal pseudoobstruction (CIPO: n = 4), short bowel syndrome (SBS: n = 2), and intestinal atresia (n = 1). All patients orally received NJT extract granules at a dose of 0.3 g/kg BW per day. The treatment outcomes were then assessed according to the patients' symptoms and consecutive abdominal X-ray findings. Results. The targeted symptoms were abdominal distension in four patients, diarrhea in three patients, and frequent hospitalization due to infections in two patients. An improvement in the symptoms was observed in six of the seven patients, whereas one patient with SBS did not show any improvement. An improvement in an abdominal roentgenogram was observed in the four patients with remarkably dilated bowel loops due to CIPO. Conclusions. NJT may be effective in controlling functional gastrointestinal disorders associated with chronic intestinal failure. The use of Kampo medicine in the field of pediatric surgery may help to improve the quality of life in children suffering from such conditions. PMID:26495014

    Pulmonary arterial hypertension (PAH) is a chronic, life threatening illness that affects primarily women. The purpose of this study was to describe the prevalence of PAH symptoms and to determine whether there are differences in symptom severity and HRQOL in PAH symptoms among young, middle, and older adults with PAH. A cross sectional design was utilized. For all the age groups, shortness of breath (SOB) on exertion and fatigue were the two most prevalent symptoms. SOB on exertion had the highest symptom severity scores followed by fatigue for all groups. Symptom severity was significantly different among the groups for palpitations, abdominal swelling and nausea. For components of HRQOL, physical functioning worsened with age. All groups had diminished general health, role physical and vitality levels. There are some differences in symptom prevalence, symptom severity and HRQOL among young, middle and older adults. Awareness of these differences is important for healthcare providers to know and assess overtime. Palliative care should be an integral part of caring for patients with PAH. PMID:25294227

    Background Infertility is a major life crisis which can lead to the development of psychiatric symptoms and negative effects on the quality of life of affected couples, but the magnitude of the effects may vary depending on cultural expectations. Aim We compare the level of psychiatric symptoms, disability, and quality of life in fertile and infertile women in urban Turkey. Methods This cross-sectional study enrolled 100 married women being treated for infertility at the outpatient department of the Obstetrics and Gynecology Department of the Rize Education and Research Hospital and a control group of 100 fertile married women. All study participants were evaluated with a socio-demographic data screening form, the Hospital Anxiety and Depression Scale (HADS), the Brief Disability Questionnaire (BDQ), and the Short Form Health Survey (SF-36). Results The mean anxiety subscale score and depression subscale score of HADS were slightly higher in the infertile group than in controls, but the differences were not statistically significant. The proportion of subjects with clinically significant anxiety (i.e., anxiety subscale score of HADS ≥11) was significantly higher in infertile women than in fertile women (31% v. 17%, χ2=5.37, p=0.020), but the proportion with clinically significant depressive symptoms (i.e., depression subscale score of HADS >8) was not significantly different (43% v. 33%, χ2=2.12, p=0.145). Self-reported disability over the prior month was significantly worse in the infertile group than in the controls, and 4 of the 8 subscales of the SF-36 - general health, vitality, social functioning, and mental health - were significantly worse in the infertile group. Compared to infertile women who were currently working, infertile women who were not currently working reported less severe depression and anxiety and better general health, vitality, and mental health. Conclusions Married women from urban Turkey seeking treatment for infertility do not have

    This is the first reported attempt at investigation of the sBs phenomena in mid IR fibers using externally fed or laser self generated low frequency and microwave frequency phonon waves as diagnostic probes of such processes. The observation of laser excited phonon emissions in the mid IR fiber and direct modulation of CO2 laser pulse transmission by externally imposed low frequency radiation is the first indication of the predicted low sBs threshold in these fibers in the phonon rich mid IR spectral region. The prospect of wide applications of the sBs process in optical switching, phase conjugation and ultimately optical computing and possible deleterious effects in mid IR laser heterodyne spectroscopy, sideband modulation and transmitted power limitation is discussed.

    We present experimental results of SBS suppression in high power, monolithic, Yb-doped fiber amplifiers via phase modulated laser gain competition. To narrow the linewidth, two-tone laser gain competition between broad (1036 nm) and narrow linewidth (1064 nm) laser signals is investigated in conjunction with phase modulation and yields pump limited output powers of 600 W. Here integration of both two-tone and pseudo random bit sequence (PRBS) phase modulation concepts, generated SBS enhancement factors of greater than 17x at a modulation frequency of 500 MHz, without reaching the SBS threshold. Significantly, the results represent a near order of magnitude reduction in linewidth over current high-power, monolithic, Yb-doped fiber amplifiers.

    Purpose The nonmotor symptoms (NMS) of Parkinson’s disease (PD) are important factors for quality of life (QoL). Few studies on NMS have been conducted in Asian PD patients. Additionally, effects of anti-PD drugs on risk of NMS are still controversial. We therefore conducted this hospital-based cross-sectional study to examine the clinical factors, including concomitant anti-PD medication use, on the occurrence of NMS and QoL in Taiwanese PD patients. Patients and methods PD patients who received long-term follow-up in the movement disorders clinics were enrolled and received NMS questionnaire (NMSQuest) and the 39-item Parkinson’s Disease Questionnaire (PDQ-39). Spearman’s rank correlation coefficient was checked for the correlation between clinical factors and NMSQT/PDQSI. Multiple linear regressions were applied to assess the influence of clinical factors on NMSQT/PDQSI. Results A total of 210 PD patients (mean age 66.1±9.86 years, Hoehn and Yahr stage 2.2±0.9) were included in this study. Up to 98% of patients reported at least one symptom of NMS. The most prevalent symptom was urinary complaints (56%), followed by memory/apathy (30%) and depression/anxiety (28%). The correlation between NMSQT and PDQSI was strong (rs=0.667), especially the item of depression/anxiety (rs=0.607). The regression model for NMSQT indicated that disease duration and severity, but not pharmacological therapy, were major predictors of NMS. Conclusion Our data indicated a high prevalence rate of NMS in PD patients. Among symptoms of NMS, depression and anxiety had the greatest impact on QoL. Concomitant anti-PD medication use did not affect the occurrence of NMS and QoL. PMID:26635475

    We present Giant Metrewave Radio Telescope HI observations of an extremely metal-deficient galaxy SBS 1129+576. SBS 1129+576 has a weighted mean oxygen abundance of 12 + log (O/H) = 7.41 +/- 0.07, or 1/18 of the solar value. Our HI observations show that the galaxy is strongly interacting with a companion (projected separation ~27 kpc) galaxy, SBS 1129+577. HI emission from a third, smaller galaxy, SDSS J113227.68+572142.3, is also present in the data cube. We study the HI morphology and kinematics of this small group at angular resolutions ranging from ~40 to 8arcsec. The low-resolution map shows a bridge of emission connecting the two larger galaxies and a large one-armed spiral distortion of the disc of SBS 1129+577. We measure HI masses of ~4.2 × 108, ~2.7 × 109 and ~2.1 × 108Msolar for SBS 1129+576, SBS 1129+577 and the gas in the bridge, respectively. Assuming that most of the bridge gas originally came from SBS 1129+576, approximately one-third of its original gas mass has been stripped off. The third smaller galaxy has an HI mass of (MHI ~ 1.1 × 107Msolar) and does not show any sign of interaction with the other two galaxies. The higher-resolution maps show that SBS 1129+577 has a central bar and a ring surrounding the bar; there is also a hint of an integral-shaped warp in SBS 1129+576. All these features are very likely to have been induced by the tidal interaction. In both SBS 1129+576 and SBS 1129+577, there is, in general, a good correspondence between regions with high HI column density and those with ongoing star formation. The two brightest HII regions in SBS 1129+576 have (inclination-corrected) gas column densities of ~1.6 × 1021 and ~1.8 × 1021 atoms cm-2, respectively. The inclination-corrected HI column density near the HII regions in SBS 1129+577 is generally above ~2.0 × 1021 atoms cm-2. These values are close to the threshold density for star formation observed in other blue compact galaxies. In contrast to SBS 1129+576 and SBS 1129

    Introduction Polycystic ovary syndrome is a common endocrine disorder affecting women both physically and psychologically and can lead to a poor quality of life compared to their normal counterparts. The aim of the present study was to assess the impact of various clinical features of polycystic ovary syndrome on the health-related quality of life of Iranian women diagnosed with this syndrome. Materials and Methods A total of 796 women diagnosed with polycystic ovary syndrome, aged 15–49 years, completed the questionnaires, interviews, and medical assessments required for this study. A reliable and validated Persian version of the health-related quality of life questionnaire for polycystic ovary syndrome patients was used. Linear regression models were used to assess the association between the symptoms of polycystic ovary syndrome and health-related quality of life. Results The mean age of participants was 28.02 years. 35.4% of the subjects were classified as overweight or obese. Hirsutism, was reported to have the strongest impact on the patients’ health-related quality of life, followed in descending order by body mass index, irregular menses and infertility. The relative level of hirsutism was directly proportional to decrease in health-related quality of life score (p<0.001). Conclusions The results of the study found that hirsutism had the strongest impact on the health-related quality of life measures in Iranian women diagnosed with polycystic ovary syndrome. Health care officials need to evaluate in depth the effect of each clinical feature of polycystic ovary syndrome separately and design management strategies, keeping in mind the psychological and physical manifestations.

    The primary objective of this study was to assess the effect of aromatherapy and classic massage administered in various ways to breast cancer patients on their symptoms and quality of life. The sampling consisted of 280 patients. Quality of life and symptoms of the patients were evaluated once at baseline and then at week 6 and week 10 following the intervention. After intervention, the control group was observed to have lower total quality of life score and subdomain scores, whereas fragrance, massage and aromatherapy massage groups had higher scores, and the increase was more obvious particularly in the patients in the aromatherapy massage group. Similarly, whereas psychological and physical symptoms were experienced more intensely in the control group, the severity of all the symptoms experienced by the other patients decreased at week 6 and week 10 as compared with baseline especially in the group that was administered massage with aromatherapy.

    Aim. The aim of this study was to identify the impact of bedtime, wake time, sleep duration, sleep-onset latency, and sleep quality on depressive symptoms and suicidal ideation amongst Japanese freshmen. Methods. This cross-sectional data was derived from the baseline survey of the Enhancement of Q-University Students Intelligence (EQUSITE) study conducted from May to June, 2010. A total of 2,631 participants were recruited and completed the following self-reported questionnaires: the Pittsburgh Sleep Quality Index (PSQI), the Center for Epidemiologic Studies Depression Scale (CES-D), and the original Health Support Questionnaires developed by the EQUSITE study research team. Results. Of 1,992 participants eligible for analysis, 25.5% (n = 507) reported depressive symptoms (CES-D total score ≥ 16), and 5.8% (n = 115) reported suicidal ideation. The present study showed that late bedtime (later than 01:30), sleep-onset latency (≥30 minutes), and poor sleep quality showed a marginally significant association with depressive symptoms. Poor sleep quality was seen to predict suicidal ideation even after adjusting for depressive symptoms. Conclusion. The current study has important implications for the role of bedtime in the prevention of depressive symptoms. Improving sleep quality may prevent the development of depressive symptoms and reduce the likelihood of suicidal ideation. PMID:27042358

    Using longitudinal data from the Toledo Adolescent Relationships Study (n = 927), we examined physical victimization, poor quality, and depression among young adults in casually dating, exclusively dating, cohabiting, and marital relationships. In multivariate models, victimization was a risk factor for depression with the inclusion of prior depression, family factors reflecting the intergenerational transmission of violence, sociodemographic background, and relationship characteristics including union status. With the inclusion of indicators of poor relational quality, victimization was not a significant predictor of depression. Arguing and poor communication influenced victimization and depression. Associations between victimization and depression did not differ by gender, nor were the effects of poor quality on depression conditional on gender. Thus, victimization occurs within relationships characterized by a range of negative dynamics. Multifaceted relationship-centered prevention efforts are more useful than focusing only on the use of aggression with a partner. PMID:25131276

    Background Although family influences in heart failure (HF) care are considered important, little evidence is available regarding relationships between the family context and specific outcomes for patients with HF. Objective To examine the relationships of patient perceptions of family functioning, autonomy support, and perceived criticism, as well as their family member’s (FM) HF knowledge with patient outcomes of depressive symptoms and HF quality of life (QOL). Methods Participants (n = 117) with HF were enrolled in a family partnership intervention study. Self-report questionnaires measuring the HF patient’s perceptions of family context and the FM’s knowledge were analyzed relative to the HF patient’s outcomes using correlations and sequential multivariate regression analyses. Only pre-intervention, baseline data are reported here. Results Age, ethnicity, Charlson comorbidity index, global family functioning and FM’s HF knowledge accounted for 37.8 % (p < .001) of the variance in patient’s depressive symptoms. An additional moderating effect of ethnicity on the association between global family functioning and patient’s depressive symptoms was significant (change R2 = .06, p = .001) resulting in a final model that accounted 43.3% of depressive symptom variance. Age, ethnicity, global family functioning and autonomy support accounted for 24.9% (p < .001) of the variance in emotional HF QOL. An additional moderating effect of ethnicity on the association between global family functioning and patient’s emotional HF QOL was significant (change R2 = .05, p = .009) resulting in a final model that accounted for 28.9% of emotional QOL variance. Conclusions This study underscores the importance of the patient’s perspective on family functioning and autonomy support, along with FM’s HF knowledge, on HF patient outcomes moderated by ethnicity. Future interventions could target the modifiable patient-family context relationships for improving

    Objectives Every physical abnormal criterion has an impact on the health. Late menopause causes different physiological problems which alike early menopause. The research interest is associated with both early and late menopausal women of Bangladesh as only few menopausal studies available in South East Asia especially in Bangladesh. The aims of this study are not only to assess the symptoms of menopausal abnormality but also to determine the impact of these symptoms on the quality of life (QOL) of the female society in Bangladesh. Methods Data mining techniques are used to rank the 22 factors (conducted with questionnaire) commonly associated with menopause. Among the participants menstruation that stops before 45 years was considered as early menopausal status and after 50 years as late menopausal. The mean of age and mean length of time in years, since menopause for all participants were 61.55±10.7 and 14.13±11.17, respectively. Recorded data indicated 67% were early menopausal women and 33% were late menopausal women. Results Results indicated that feeling tired or lacking in energy and dizziness (83%) and depression (82%) have worst impact on QOL among all factors, respectively. The next prevalent symptoms included hot flashes (64%), osteoporosis (72%), sweating at night (63%), concentration problem (75%), irritability (63%), feeling tense (77%), headache (66%). However, less frequent factors included breathing problems (33%), loss of feeling (31%), coherent heart disease (13%) and type2 diabetics (9%). Conclusion Our study indicates that early menopausal women are facing more physiological problems than the late menopausal women on their QOL. PMID:27152312

    Purpose We aimed primarily to investigate the level of health-related quality of life (HRQoL), lower urinary tract symptoms (LUTS), and depression in older adults and secondly to identify the impact of LUTS and depression on HRQoL. Methods A community-based cross-sectional study was conducted from April to November 2010. Participants were recruited from five community senior centers serving community dwelling older adults in Jeju city. Data analysis was based on 171 respondents. A structured questionnaire was used to guide interviews; the data were collected including demographic characteristics, body mass index, adherence to regular exercise, comorbidities (hypertension, diabetes mellitus, and osteoarthritis), depression, urinary incontinence, LUTS (measured via the International Prostate Symptom Score [IPSS]), and HRQoL as assessed by use of the EQ-5D Index. Stepwise multiple regression analysis was used to test predictors of HRQoL. Results Eighteen percent (18.6%) of the respondents reported depressive symptoms. The mean LUTS score was 8.9 (IPSS range, 0 to 35). The severity of LUTS, was reported to be mild (score, 0 to 7) by 53% of the respondents, moderate (score, 8 to 19) by 34.5%, and severe (score, 20 to 35) by 12.5%. HRQoL was significantly predicted by depression (Partial R2=0.193, P<0.01) and LUTS (Partial R2=0.048, P=0.0047), and 24% of the variance in HRQoL was explained. Conclusions LUTS and depression were the principal predictors of HRQoL in older adults. PMID:23094219

    Introduction Transurethral resection of the prostate (TURP) still remains the most popular surgical treatment for patients with lower urinary tract symptoms. However, in some patients, the improvement of symptoms after TURP is insufficient. The aim of our study was to evaluate the impact of the resected prostate tissue weight (RPTW) on the improvement of symptoms (IPSS), quality of life (QoL), and voiding function after TURP. Material and methods The study included 89 men who had undergone TURP in our institution. IPSS, QoL, post–voiding residual urine volume (PVR) and Qmax were recorded before the operation and six months after TURP. The total prostate volume (TPV) and transition zone volume (TZV) were measured before the operation by transrectal ultrasound. The impact of RPTW, RPTW/TZV ratio, and RPTW/TPV ratio were analyzed according to the efficacy of TURP. Results The mean Qmax after TURP increased by 10.15 mL/s, IPSS decreased by 16.7 points, QoL increased by 3.57 points, and PVR decreased by 95.3 mL. According to Qmax, the treatment was effective in 74.2%, according to IPSS, in 91%, and according to QoL, in 74.2% of patients. The ROC analysis demonstrated that RPTW/TZV and RPTW/TPV ratios were the most significant predictors of obtaining favorable results. Survival analysis (life table) shows that in order to achieve 50% improvement on Qmax, QoL, and IPSS, more than 30–35% of TPV and more than 60% of the TZV should be removed. Conclusions The efficacy of the TURP at short term follow-up depends on the completeness of the resection. PMID:26251736

    PURPOSE Sleep duration among breast cancer survivors correlates with fatigue, depression, and health-related quality of life (HRQOL); however, this has not been studied longitudinally. This study investigated patterns of sleep duration change across the early breast cancer survivorship period, their demographic and clinical predictors, and their relationships with subsequent cancer-related symptoms and HRQOL. METHODS Breast cancer survivors (n=572), were assessed 6 months post-diagnosis (current sleep & retrospective reports of pre-diagnosis sleep), 30 months post-diagnosis (sleep), and 39 months post-diagnosis (symptoms, HRQOL). Sleep duration change was determined by examining sleep at each time point in relation to published norms. Analysis of variance and logistic regression models tested demographic and clinical differences between the sleep change groups; linear regression models tested differences in symptoms and HRQOL. RESULTS Half of the survivors reported no sleep duration change over time; however, 25% reported sleep changes indicating a temporary (5.6%), late-occurring (14%), or sustained (5.9%) change. Survivors reporting sustained or temporary sleep changes were more likely to have been treated with chemotherapy (OR=2.62, p<.001) or gained weight after diagnosis (OR=1.82, p=.04) than those with no sleep change. Sustained sleep changes were related to greater subsequent severity, affective, and sensory aspects of fatigue (βs=2.0, 2.3, 1.8; all p <.0001) and lower vitality (β=−10.8, p=.005). CONCLUSIONS Survivors treated with chemotherapy and those who gain weight after diagnosis may have increased risk for sustained sleep duration changes, which may increase their fatigue. These results point to the need for routine assessment of sleep as part of survivorship care. PMID:21567239

    There is increasing interest in the use of patient-reported outcomes (PROs) in routine practice in cancer care to measure symptoms and health related quality of life (HRQOL). PROs are designed to capture the patient's perspective of their care and treatment, and complement the traditional clinical outcomes of survival and toxicity assessment. Integrating routine collection and feedback of PROs has been found to improve care for patients on both an individual level, through improved communication and management of symptoms, and at an organizational level, by enabling aggregation of data to compare performance. This article reviews the benefits and challenges of introducing patient-reported assessments into routine clinical practice. Methods for choosing a questionnaire; collection and presentation of results; timing and frequency of administration as well as clinician training methods to aid the ability of clinicians to integrate the use of PROs into their own practice are described. Electronic PRO capture and integration with electronic health records seems to provide the most effective method for seamless integration into existing patient care pathways. Case studies from our own practice illustrate the issues raised. Electronic methods enabling immediate collection, scoring and interpretation of the data, as well as real-time data capture, email alert systems and individualized, online self-management advice may enable severe symptoms to be managed in a more timely manner. Evaluation methods are described to establish the effectiveness of the PRO intervention. Engaging stakeholders throughout the process of initial consultation and development, during delivery and evaluation is key to success. Future work needs to focus on the effectiveness of PROs in longer-term follow-up of patients in routine care and the relationship between the PRO severity grading and clinician severity grading using the Common Terminology Criteria of Adverse Events (CTCAE).

    Objective The diagnosis and treatment of cancer is a potentially traumatic experience that may evoke posttraumatic stress symptoms (PTSS) among survivors. This paper describes the rates of endorsement of cancer-related PTSS along with the relationship of demographic, cancer, and combat variables on PTSS and quality of life. Methods Veterans (N = 166) with head and neck, esophageal, gastric, or colorectal cancers were recruited through tumor registries at two regional Veterans Administration Medical Centers. Standardized scales were used to assess self-report of PTSS, combat, and quality of life. Results Most participants (86%) reported experiencing at least some cancer-related PTSS; 10% scored above a clinical cutoff for probable PTSD. In linear regressions, younger age and current combat PTSS were associated with cancer-related PTSS, whereas disease and treatment characteristics were not; in turn, cancer-related PTSS were negatively associated with physical and social quality of life. Conclusions Individual characteristics and psychosocial factors may play a larger role than disease-related variables in determining how an individual responds to the stress of cancer diagnosis and treatment. Given the rates of reported cancer-related PTSS in this sample, and other non-veteran samples, clinicians should consider screening these following diagnosis and treatment, particularly in younger adults and those with previous trauma histories.

    Two organophilic bentonites, based on nitrogen-containing compounds, have been synthesised via ion exchange starting from pristine bentonite with octadecyltrimethylammonium bromide (OTAB) and with synthetic melamine-derived N2,N4-dihexadecyl-1,3,5-triazine-2,4,6-triamine (DEDMEL). The chemical and morphological characterization of the organoclays was based on XRD, TEM, Laser Granulometry, X-Ray Fluorescence and CEC capacity. Copoly(styrene-butadiene-styrene)-nanocomposites (SBS-nanocomposites) were obtained by intercalation of the SBS-copolymer into these new organoclays by melt intercalation method. XRD and TEM analysis of the organoclays and of the micro/nano-composites obtained are presented. The effect of the organoclays on the SBS-nanocomposite's flammability properties was investigated using cone calorimeter. An encouraging decrease of 20% in the peak heat released rate (PHRR) has been obtained confirming the important role of melamine's based skeleton and its derived organoclays to act as effective fire retardants and for the improvement of this important functional property in SBS copolymers.

    Objectives To identify clinical, functional and health-related quality of life (HRQoL) correlates of clinically significant symptoms of anxiety and depression in patients with systemic sclerosis (SSc). Methods Three-hundred-and-eighty-one patients fulfilling the American College of Rheumatology and/or the Leroy and Medsger criteria for SSc were assessed for visceral involvement, disability and HRQoL (assessed by SF-36). Clinically significant symptoms of anxiety and depression were evaluated with the Hospital Anxiety Depression Scale (HAD) (defined cut-off≥8). Results 9.2% the patients had limited SSc, 50.5% limited cutaneous SSc (lcSSc), and 40.3% diffuse cutaneous SSc (dcSSc). Overall, 40.4% and 58.8% of the patients had clinically significant symptoms of depression and anxiety, respectively. Compared to patients without clinically significant symptoms of depression, patients with clinically significant symptoms of depression had poorer health status, HRQoL mental and physical component, and greater global disability, hand disability and aesthetic impairment. Compared to patients without clinically significant symptoms of anxiety, patients with clinically significant symptoms of anxiety had poorer SF-36 mental and physical component scores. On multivariable analysis, excluding mental component score of SF-36, variables independently associated with clinically significant symptoms of depression and anxiety were global disability and physical component of SF-36, plus female gender for clinically significant symptoms of anxiety only. Remarkably, patients with and without clinically significant psychiatric symptoms were comparable for all disease-related clinical features assessed. Conclusion High levels of clinically significant symptoms of anxiety and depression are observed among SSc patients. Clinically significant psychiatric symptoms are rather associated with increased disability and altered HRQoL, than with disease-specific organ manifestations. PMID

    Objectives Real-world patient outcomes data is scarce concerning the high disease burden of IBS-C. The aim of this study was to compare patient-reported symptom control, health-related quality of life (HRQoL), resource utilization, and treatment satisfaction of lubiprostone vs non-lubiprostone treatment for irritable bowel syndrome-constipation (IBS-C). Research design and methods An observational, retrospective US chart review and computer-assisted telephone patient survey was conducted March to August 2013 recruiting women over 18 years old with physician-confirmed IBS-C who had initiated new treatment from inadequate relief of previous treatments and who had been on the new treatment ≥3 months. Multiple IBS-C treatments were permitted. IBS-C severity, time since diagnosis, age, and race were controlled using inverse probability of treatment weighting. Weighted outcomes were compared using t-tests (continuous outcomes) and chi-squared tests (categorical outcomes). Main outcomes measures Instruments included Patient Assessment of Constipation Symptoms (PAC-SYM) and IBS quality of life (IBS-QoL). A single item assessed current treatment satisfaction. Results Of 162 patients (mean age 45.9 [SD 15.3] years old, 71% white, 61.1% with moderate IBS-C), 76 switched to lubiprostone and 86 to non-lubiprostone. Groups were similar in clinical and demographic characteristics and previous 30 day IBS-C treatment. After weighting, all PAC-SYM scores were lower for lubiprostone (P < 0.05). All IBS-QoL subscales were higher for lubiprostone including overall, dysphoria, social reaction, sexual, and relationship scores (P < 0.05.) More lubiprostone patients reported positive treatment satisfaction (92.3% vs 71.0%, P < 0.001). Conclusions In IBS-C patients with inadequate response to previous therapies, lubiprostone improved patient-reported symptom control, treatment satisfaction, and HRQoL. Key limitations include lack of measurement of patient-reported outcomes

    About 400,000 people worldwide are diagnosed with oral squamous cell carcinoma (SCC) annually, and the incidence is increasing. Many advanced carcinomas of the oral cavity require radical surgical treatment that can impair patient's quality of life (QoL) and severity of symptoms. We therefore aimed to identify coping strategies and disease-specific medical factors that affect QoL and severity of symptoms. Patients with oral SCC were asked to complete the Freiburg Questionnaire on Coping with Illness (FQCI), the University of Washington Quality of life Questionnaire (UW-QOL version 4), and the Brief Symptom Inventory (BSI) to measure psychological stress. We also assessed the impact of various factors on QoL and severity of symptoms, including stage and site of tumour, method of reconstruction, time of diagnosis, and social structure (age, sex, marital status, living arrangements, level of education, and employment). We enrolled a consecutive sample of 104 patients over a period of one year. Stepwise linear regression analyses indicated that both depressive coping and size of tumour had an adverse effect on QoL and severity of symptoms. Patients with high educational attainment and those who lived alone reported impaired QoL, and women experienced increased severity of symptoms. Impaired QoL and increased severity of symptoms were associated with a depressive style of coping, size of tumour, educational attainment, and living arrangements. It is important to identify these patients during treatment as they could benefit from psycho-oncological counselling. PMID:25698550

    Pain, a debilitating condition, is frequently reported by U.S. veterans returning from Afghanistan and Iraq. This study investigated how commonly reported clinical factors were associated with pain and whether these associations differed for individuals with a history of chronic pain. From the Boston metropolitan area, 171 veterans enrolled in the Veterans Affairs Center of Excellence were assessed for current posttraumatic stress disorder (PTSD) symptom severity, current mood and anxiety diagnoses, lifetime traumatic brain injury, combat experiences, sleep quality, and alcohol use. Hierarchical regression models were used to determine the association of these conditions with current pain. Average pain for the previous 30 days, assessed with the McGill Pain Questionnaire, was 30.07 out of 100 (SD = 25.43). Sleep quality, PTSD symptom severity, and alcohol use were significantly associated with pain (R(2) = .24), as were reexperiencing symptoms of PTSD (R(2) = .25). For participants with a history of chronic pain (n = 65), only PTSD symptoms were associated with pain (R(2) = .19). Current pain severity was associated with increased PTSD severity (notably, reexperiencing symptoms), poor sleep quality, and increased alcohol use. These data support the hypothesis that PTSD symptoms influence pain, but suggest that problems with sleep and alcohol use may exacerbate the relationship. PMID:26194844

    Physiotherapy is concerned with identifying and maximizing movement potential, within the spheres of promotion, prevention, treatment and rehabilitation. Physical therapists practice in a broad range of inpatient, outpatient, and community-based settings such as hospice and palliative care centers where as part of a multidisciplinary team of care, they address the physical and functional dimensions of the patients’ suffering. Physiotherapy treatment methods like therapeutic exercise, electrical modalities, thermal modalities, actinotherapy, mechanical modalities, manual physical therapy and assistive devices are useful for a range of life-threatening and life-limiting conditions like cancer and cancer-associated conditions; HIV; neurodegenerative disorders like amyotrophic lateral sclerosis, multiple sclerosis; respiratory disorders like idiopathic pulmonary fibrosis; and altered mental states. The professional armamentarium is still expanding with inclusion of other miscellaneous techniques which were also proven to be effective in improving quality of life in these patients. Considering the scope of physiotherapy in India, and in palliative care, professionals in a multidisciplinary palliative care team need to understand and mutually involve toward policy changes to successfully implement physical therapeutic palliative care delivery.

    Purpose Thanks to advancements in surgical techniques and instruments, many surgical modalities have been developed to replace transurethral resection of the prostate (TURP). However, TURP remains the gold standard for the surgical treatment of benign prostatic hyperplasia (BPH). We conducted a meta-analysis on the efficacy and safety of minimally invasive surgical therapies for BPH compared with TURP. Methods This meta-analysis used a Medline search assessing the period from 1997 to 2011. A total of 784 randomized controlled trials were identified in an electronic search. Among the 784 articles, 36 randomized controlled trials that provided the highest level of evidence (level 1b) were included in the meta-analysis. We also conducted a quality analysis of selected articles. Results Only 2 articles (5.56%) were assessed as having a low risk of bias by use of the Cochrane collaboration risk of bias tool. On the other hand, by use of the Jadad scale, there were 26 high-quality articles (72.22%). Furthermore, 28 articles (77.78%) were assessed as high-quality articles by use of the van Tulder scale. Holmium laser enucleation of the prostate (HoLEP) showed the highest reduction of the International Prostate Symptom Score compared with TURP (P<0.0001). Bipolar TURP, bipolar transurethral vaporization of the prostate, HoLEP, and open prostatectomy showed superior outcome in postvoid residual urine volume and maximum flow rate. The intraoperative complications of the minimally invasive surgeries had no statistically significant inferior outcomes compared with TURP. Also, there were no statistically significant differences in any of the modalities compared with TURP. Conclusions The selection of an appropriate surgical modality for BPH should be assessed by fully understanding each patient's clinical conditions. PMID:23869269

    Study Objectives: We examined the effects of a cognitive behavioral self-help program (Refresh) to improve sleep, on sleep quality and symptoms of depression among first-year college students. Methods: Students in one residence hall (n = 48) participated in Refresh and students in another residence hall (n = 53) participated in a program of equal length (Breathe) designed to improve mood and increase resilience to stress. Both programs were delivered by e-mail in 8 weekly PDF files. Of these, 19 Refresh program participants and 15 Breathe program participants reported poor sleep quality at baseline (scores ≥ 5 on the Pittsburgh Sleep Quality Index [PSQI]). Participants completed the PSQI and the Center for Epidemiological Studies-Depression Scale (CES-D) at baseline and post-intervention. Results: Among students with poor sleep (PSQI > 5) at baseline, participation in Refresh was associated with greater improvements in sleep quality and greater reduction in depressive symptoms than participation in Breathe. Among students with high sleep quality at baseline there was no difference in baseline to post-intervention changes in sleep (PSQI) or depressive symptom severity (CES-D). Conclusions: A cognitive behavioral sleep improvement program delivered by e-mail may be a cost effective way for students with poor sleep quality to improve their sleep and reduce depressive symptoms. An important remaining question is whether improving sleep will also reduce risk for future depression. Citation: Trockel M; Manber R; Chang V; Thurston A; Tailor CB.

    Abstract The impact of psychosocial status at onset of antiretroviral therapy on changes in quality of life (QOL) and subjectively rated health (SRH) among adults on highly active antiretroviral therapy (HAART) in resource-limited settings is poorly understood. Therefore, we evaluate the association between stigma, anxiety, depression, and social support and change in QOL and SRH in HIV-infected Ugandan adults during an 18-month period. Psychosocial indicators were assessed at enrollment using structured questionnaires. QOL and SRH measures were assessed at months 0, 6, 12, and 18 using the Medical Outcomes Survey-HIV. Linear mixed models determined risk estimated differences in QOL and SRH in relation to quartiles of each psychosocial status indicator. Repeated measures generalized estimating equations modeling was implemented to assess differences in likelihood of improved versus nonimproved SRH during follow-up. QOL scores and SRH improved significantly for all participants over 18 months (P < 0.0001). The gain in QOL increased dose-dependently as baseline depressive symptoms (time∗depression P < 0.001) and anxiety levels (time∗anxiety P < 0.001) declined. Lower social support was associated with worse QOL at baseline (P = 0.0005) but QOL improvement during follow-up was not dependent on baseline level of social support (time∗social support P = 0.8943) or number of stigmatizing experiences (time∗stigma P = 0.8662). Psychosocial determinants did not predict changes in SRH in this study. High levels of depression and anxiety symptoms at HAART initiation predicts lower gains in QOL for HIV-positive patients for as long as 18 months. Long-term QOL improvements in HIV-infected adults may be enhanced by implementation of psychosocial interventions to reduce depression and anxiety in HIV-infected adults. PMID:26945347

    The purposes of this study, in oncology outpatients receiving chemotherapy (n = 926), were to: describe the occurrence of different types of pain (ie, no pain, only noncancer pain [NCP], only cancer pain [CP], or both CP and NCP) and evaluate for differences in demographic, clinical, and symptom characteristics, and quality of life (QOL) among the 4 groups. Patients completed self-report questionnaires on demographic and symptom characteristics and QOL. Patients who had pain were asked to indicate if it was or was not related to their cancer or its treatment. Medical records were reviewed for information on cancer and its treatments. In this study, 72.5% of the patients reported pain. Of the 671 who reported pain, 21.5% reported only NCP, 37.0% only CP, and 41.5% both CP and NCP. Across the 3 pain groups, worst pain scores were in the moderate to severe range. Compared with the no pain group, patients with both CP and NCP were significantly younger, more likely to be female, have a higher level of comorbidity, and a poorer functional status. In addition, these patients reported: higher levels of depression, anxiety, fatigue, and sleep disturbance; lower levels of energy and attentional function; and poorer QOL. Patients with only NCP were significantly older than the other 3 groups. The most common comorbidities in the NCP group were back pain, hypertension, osteoarthritis, and depression. Unrelieved CP and NCP continue to be significant problems. Oncology outpatients need to be assessed for both CP and NCP conditions. PMID:26683234

    In recent years, employees at the three headquarters buildings of the U.S. Environmental Protection Agency (EPA) in the Washington, D.C. area have expressed concerns about air quality and work environment discomforts. As part of a large-scale study of health and comfort concerns, environmental monitoring was carried out in March 1989 at approximately 100 sites (rooms) within these buildings. Employees in the vicinity of the monitors were administered a brief questionnaire to elicit information regarding their work environment, comfort levels, odors noticed, health symptoms, mood states, and perceptions of overall air quality. Statistical analyses were carried out for the 191 males and the 192 females for whom both questionnaire and monitoring data were available. The analyses entailed estimation of linear regression and logistic regression models aimed at testing for associations between the employees' responses and the environmental measurements, which included temperature, humidity, carbon dioxide, and particlate concentrations (100 sites), and various microbiologic and volatile organic compound concentrations (subset of 56 sites). Principal component analyses were used to develop some of the outcome and explanatory variables used in the models. In the paper, the authors describe the study design, the study limitations, the statistical models and methods, and the results and implications of the data analysis.

    To our knowledge there are no studies evaluating the prevalence and characteristics of itch, pain, and burning sensation among patients with mild to moderate chronic venous insufficiency or assessing the impact of these symptoms on quality of life. In this report 100 patients met the inclusion criteria. Patients who suffered from itch were also assessed with the use of a validated questionnaire and a modified Skindex-16 questionnaire. We found that the prevalence of itch was 66%. Concomitant itch and burning sensation as well as itch and pain were noted in 47% and 44% of the patients, respectively. No correlation was noted between the severity of these symptoms and the degree of venous insufficiency. Itch had a negative impact on quality of life. A limitation of this study is that the participants, who were primarily hospital employees, are more likely to develop these symptoms. Therefore this study does not reflect the true prevalence of these symptoms in the general population. This study found that itch, pain, and burning sensation are common symptoms of mild to moderate chronic venous insufficiency with a significant impact on quality of life. PMID:16112363

    We demonstrate a new and simple solution to suppress stimulated Brillouin scattering in fiber optical parametric amplifiers. Cumbersome PRBS or sinusoidal generators used to broaden the pump spectrum are replaced by a filtered microwave noise source. Stimulated Brillouin scattering threshold can be increased up to large values still keeping an excellent quality of amplification of nonreturn to zero signals. The simplicity and the performances of this setup open the way for a wide variety of applications for FOPAs.

    The physical mechanisms that make STUD pulses (spike trains of uneven duration and delay) optimal rely, among other physical effects, on damping of the driven waves in between spikes. By varying the damping of ion acoustic waves in inhomogeneously flowing plasma regions ranging from -8 to -2 of the Mach number, we can establish to what extent STUD pulses can be effective to control SBS growth in various damping levels. By changing the duty cycle of the chain of spikes, by changing their modulation period, by adding random inter spike phase kicks and by changing the spatial hot spot profile scrambling rate, we establish bounds on how much Brillouin backscattering Rosenbluth gain can be tolerated at the average intensity and still have STUD pulses control SBS as compared to RPP or SSD or ISI. The situation is complicated by the implication of the strong coupling regime in hot spots, by pump depletion and by initial noise level dependencies which we also examine.

    High molecular weight, high functionality diamino telechelic polybutadienes (TPBs) were synthesized by ring-opening metathesis polymerization (ROMP) of 1,5-cyclooctadiene (COD) in the presence of a chain transfer agent, 1,8-dicyano-4-octene, followed by lithium aluminum hydride reduction. Melt coupling of diamino TPB with anhydride-terminated polystyrene (PS-anh) resulted in the formation of styrene-butadiene-styrene (SBS) triblock copolymers; ca. 80% maximum conversion of PS-anh was achieved within 30 seconds. The results from SAXS, TEM, and rheological measurements of the coupling products confirmed the formation of SBS triblock copolymers having lamellar morphology. A fluororesent-labeled PS-anh was used to study the coupling kinetics by diluting the reactants by the addition of non-functional PS. PMID:19907636

    White noise phase modulation (WNS) and pseudo-random binary sequence phase modulation (PRBS) are effective techniques for mitigation of nonlinear effects such as stimulated Brillouin scattering (SBS); thereby paving the way for higher power narrow linewidth fiber amplifiers. However, detailed studies comparing both coherent beam combination and the SBS suppression of these phase modulation schemes have not been reported. In this study an active fiber cutback experiment is performed comparing the enhancement factor of a PRBS and WNS broadened seed as a function of linewidth and fiber length. Furthermore, two WNS and PRBS modulated fiber lasers are coherently combined to measure and compare the fringe visibility and coherence length as a function of optical path length difference. Notably, the discrete frequency comb of PRBS modulation provides a beam combining re-coherence effect where the lasers periodically come back into phase. Significantly, this may reduce path length matching complexity in coherently combined fiber laser systems.

    The radii and radii of curvature of Stokes stimulated Brillouin scattering (SBS) beams are measured by the method of moments for smooth nearly Gaussian focused pump beams with the propagation ratio M{sup 2}{sub {sigma}p{<=}}1.2. It is shown that in the case of sufficiently deeply focused pump radiation, the propagation ratio M{sup 2}{sub {sigma}S} of Stokes beams near the threshold of the transient SBS is smaller than M{sup 2}{sub {sigma}p} and approaches it with increasing the pump pulse energy. It is also found that the radii of Stokes beams at the output from a nonlinear medium are smaller than the radii of pump beams, while the radii of wave-front curvature are close (in modulus) to the radii of wave-front curvature for pump beams.

    A preliminary analysis is given of 2D spectroscopic data on the galaxy SBS 1533+574(AB) obtained using the multipupil spectrographs on the 2.6-m telescope at the BAO (VAGR) and the 6-m telescope at the SAO (MPFS). The two components of the galaxy are star formation regions in different stages. The component SBS 1533+574B is known to be a BCDG. The plots of the intensity distribution of the radiation in the recombination lines of hydrogen and the forbidden lines of gases with a low degree of ionization obtained here make it possible to compare the basic characteristics of the HII-zones and the surrounding shell. The velocity distribution over the field of the galaxy is indicative of a common rotation of the system and of an intrinsic rotation of the components which is more distinct for component B.

    Objective. There are limited data on the effects of financial distress (FD) on overall suffering and quality of life (QOL) of patients with advanced cancer (AdCa). In this cross-sectional study, we examined the frequency of FD and its correlates in AdCa. Patients and Methods. We interviewed 149 patients, 77 at a comprehensive cancer center (CCC) and 72 at a general public hospital (GPH). AdCa completed a self-rated FD (subjective experience of distress attributed to financial problems) numeric rating scale (0 = best, 10 = worst) and validated questionnaires assessing symptoms (Edmonton Symptom Assessment System [ESAS]), psychosocial distress (Hospital Anxiety and Depression Scale [HADS]), and QOL (Functional Assessment of Cancer Therapy-General [FACT-G]). Results. The patients’ median age was 60 years (95% confidence interval [CI]: 58.6–61.5 years); 74 (50%) were female; 48 of 77 at CCC (62%) versus 13 of 72 at GPH (18%) were white; 21 of 77 (27%) versus 32 of 72 (38%) at CCC and GPH, respectively, were black; and 7 of 77 (9%) versus 27 of 72 (38%) at CCC and GPH, respectively, were Hispanic (p < .0001). FD was present in 65 of 75 at CCC (86%; 95% CI: 76%–93%) versus 65 of 72 at GPH (90%; 95% CI: 81%–96%; p = .45). The median intensity of FD at CCC and GPH was 4 (interquartile range [IQR]: 1–7) versus 8 (IQR: 3–10), respectively (p = .0003). FD was reported as more severe than physical distress, distress about physical functioning, social/family distress, and emotional distress by 45 (30%), 46 (31%), 64 (43%), and 55 (37%) AdCa, respectively (all significantly worse for patients at GPH) (p < .05). AdCa reported that FD was affecting their general well-being (0 = not at all, 10 = very much) with a median score of 5 (IQR: 1–8). FD correlated (Spearman correlation) with FACT-G (r = −0.23, p = .0057); HADS-anxiety (r = .27, p = .0014), ESAS-anxiety (r = .2, p = .0151), and ESAS-depression (r = .18, p = .0336). Conclusion.

    Background We conducted in two parts a systematic review of randomized controlled trials (RCTs) on electronic symptom reporting between patients and providers to improve health care service quality. Part 1 reviewed the typology of patient groups, health service innovations, and research targets. Four innovation categories were identified: consultation support, monitoring with clinician support, self-management with clinician support, and therapy. Objective To assess the methodological quality of the RCTs, and summarize effects and benefits from the methodologically best studies. Methods We searched Medline, EMBASE, PsycINFO, Cochrane Central Register of Controlled Trials, and IEEE Xplore for original studies presented in English-language articles between 1990 and November 2011. Risk of bias and feasibility were judged according to the Cochrane recommendation, and theoretical evidence and preclinical testing were evaluated according to the Framework for Design and Evaluation of Complex Interventions to Improve Health. Three authors assessed the risk of bias and two authors extracted the effect data independently. Disagreement regarding bias assessment, extraction, and interpretation of results were resolved by consensus discussions. Results Of 642 records identified, we included 32 articles representing 29 studies. No articles fulfilled all quality requirements. All interventions were feasible to implement in a real-life setting, and theoretical evidence was provided for almost all studies. However, preclinical testing was reported in only a third of the articles. We judged three-quarters of the articles to have low risk for random sequence allocation and approximately half of the articles to have low risk for the following biases: allocation concealment, incomplete outcome data, and selective reporting. Slightly more than one fifth of the articles were judged as low risk for blinding of outcome assessment. Only 1 article had low risk of bias for blinding of

    Styrene-butadiene-styrene (SBS) triblock copolymer has been conventionally used as synthetic rubber. However, the potential of SBS for biomedical applications has only been considered in limited earlier reports. Here, we demonstrate an effective approach to designing a photocrosslinked SBS network. Rheological analysis has been conducted for the investigation of the storage modulus of the resultant network. Crosslinked SBS networks were synthesized and characterized through optical and electron microscope imaging. The crosslink density of the network, calculated from swelling experiments, was 643 mol m(-3), where higher swelling in a hydrophobic medium was observed compared to the swelling measured in water. Cell survival analysis with HeLa cells and NIH/3T3 fibroblasts revealed that these networks are non-toxic, and that they could be considered for a variety of biomedical applications. PMID:26526076

    Background Several publications have focused on accompanying non-motor symptoms (NMS) in essential tremor (ET) patients; however, it remains unclear if NMS are an intrinsic part of the disease or secondary phenomena. We present the results of several neuropsychiatric tests and their impact on quality of life (QoL) in community-dwelling patients with ET. Methods Participants were recruited via a newspaper article about ET published in the local media and on the internet. All participants completed several standard neuropsychiatric tests, including those that assess QoL. To compare differences between cases and controls, Student’s t-tests with Bonferroni-Holm post hoc tests were performed. Spearman’s correlation coefficients were also calculated. Results We enrolled 110 patients with definite or probable ET. Highly significant changes were observed for apathy, anxiety, and cognition and negatively impacted QoL. Most aberrations were independent of tremor severity and duration. Discussion The significant neuropsychiatric deficits and reduced QoL demonstrate a degree of illness that appears to be a non-motor phenotype rather than a secondary effect of ET. In the future, NMS should carefully be explored in ET patients as they may have an impact on QoL and treatment. PMID:26989573

    Disordered speech and language deficits are well-documented in schizophrenia-spectrum disorders. Researchers often assess speech samples using manualized rating systems, though recently computerized language assessment methods have been used more frequently in the study of speech from people with schizophrenia. Most typically, these computerized assessments measure aspects of expressivity (i.e., pause durations, prosody) or use word-count technology; less attention has focused on similar methods that can capture more sophisticated aspects of linguistic complexity (e.g., idea density). The primary objective of the present study was to assess idea density - via a computerized measure - in the life-story narratives of people with schizophrenia (n=32) compared to a group of community control participants (n=15). In the schizophrenia group, we also examined associations between idea density, narrative qualities rated via a manualized measure, and psychiatric symptoms. Our findings indicate that idea density is diminished in individuals with schizophrenia compared to controls. Further, our results suggest that though people with schizophrenia with richer idea density tended to have more developed insight into illness, they also had higher levels of depression, anxiety, and avolition. Implications of these results and suggestions for future research are discussed. PMID:26925799

    Objectives. To compare the severity of LUTS among middle aged and elderly Nigerian men and determine the influence of LUTS severity on QoL. Methods. This cross-sectional study was conducted among new patients presenting with LUTS attending Urology clinic between 2011 and 2015. Assessment of symptoms was based on IPSS and bother score completed by the eligible subjects on the same day of their clinic visits. Results. Four hundred patients were studied comprising 229 middle aged and 171 elderly men. Interquartile range (IQR) of IPSS scores for men <65 years and those ≥65 years was 14.0 (16.0) and 19 (15.0), respectively (p < 0.001). Mild LUTS was significantly associated with best, good, and poor quality of life while moderate LUTS was associated with poor QoL. Severe LUTS was significantly associated with all the categories of QoL (Best-Worst). Among the cohort of subjects with poor QoL, elderly patients had a significantly higher median IPSS score (p < 0.05). Conclusions. There is no level of severity of LUTS in which patients' QoL is not impaired although mild symptomatology may be associated with better QoL and severe symptomatology with poor QoL. Careful attention to QoL may help identify patients who require early and prompt treatment irrespective of the IPSS. PMID:27413368

    Objective: To investigate the relationship between the characteristics of somatic symptoms and depression severity, quality of life (QOL), and health resources utilization in patients with major depressive disorder (MDD) in primary care setting. Method: This cross-sectional, nationwide epidemiologic study, carried out in 1150 primary care patients with DSM-IV–defined MDD, evaluated the characteristics of somatic symptoms by means of the Standardized Polyvalent Psychiatric Interview. Depression severity and QOL were evaluated by means of the Zung Self-Rating Depression Scale (SDS) and the Physical and Mental Component Summaries of the Medical Outcomes Study 12-item Short-Form Health Survey. Health resources utilization was measured in terms of doctor consultations and hospitalizations. The associations were assessed by means of adjusted analyses. The study was carried out from April 2004 to July 2004. Results: Disability associated with somatic symptoms and number of somatic symptoms were strongly associated with increased depression severity (2.45 and 0.29 increase in SDS score, respectively) and health resources utilization (odds ratios of 1.42 and 1.04, respectively). Associated disability, frequency, and persistence during leisure time of somatic symptoms were strongly associated with poorer QOL. In contrast, we found a weaker relationship between duration and intensity of somatic symptoms and depression severity, QOL, and health resources utilization. Conclusions: Of the studied somatic symptom characteristics, somatic symptom–associated disability and number of somatic symptoms are strongly associated with increased depression severity and health resources utilization, as well as with decreased QOL. Our results may help physicians identify relevant characteristics of somatic symptoms to more effectively diagnose and treat depression in primary care patients. PMID:19158973

    This article is a continuation of our study of the galaxy SBS 1202+583 (VV270ab) by using panoramic spectroscopy data obtained in our observations with multipupil spectrographs - the MPFS at the 6-m telescope of the SAO of the Russian Academy of Sciences and the `'VAGR" at the 2.6-m telescope of the BAO in Armenia. An analysis of the radial velocity field in the Hα emission line of this object, previously characterized as a complex consisting of more than nine HII regions [1], indicates the two main substructures of them. The closest substructure associated with the HII region SBS1202+583C1 (from the component VV270b) is disintegrating under the influence of a distant substructure associated with SBS1202+583NE4 (from the component VV270a) which is the most massive and most powerful Hα emission source. The perturbation field, owing to its gravitational effect, stimulates a directed motion of most of the HII regions as they rotate simultaneously.

    A technique that employs two seed signals for the purpose of mitigating stimulated Brillouin scattering (SBS) effects in narrow-linewidth Yb-doped fiber amplifiers is investigated theoretically by constructing a self-consistent model that incorporates the laser gain, SBS, and four-wave mixing (FWM). The model reduces to solving a two-point boundary problem consisting of an 8x8 system of coupled nonlinear differential equations. Optimal operating conditions are determined by examining the interplay between the wavelength separation and power ratio of the two seeds. Two variants of this 'two-tone' amplification are considered. In one case the wavelength separation is precisely twice the Brillouin shift, while the other case considers a greater wavelength separation. For the former case, a two-fold increase in total output power over a broad range of seed power ratios centered about a ratio of approximately 2 is obtained, but with fairly large FWM. For the latter case, this model predicts an approximately 100% increase in output power (at SBS threshold with no signs of FWM) for a 'two-tone' amplifier with seed signals at 1064nm and 1068nm, compared to a conventional fiber amplifier with a single 1068nm seed. More significantly for this case, it is found that at a wavelength separation greater than 10nm, it is possible to appreciably enhance the power output of one of the laser frequencies. PMID:18773034

    Introduction The neighbourhood environment can assist the adoption and maintenance of an active lifestyle and affect the physical and mental well-being of older adults. The psychosocial and behavioural mechanisms through which the environment may affect physical and mental well-being are currently poorly understood. Aim This observational study aims to examine associations between the physical and social neighbourhood environments, physical activity, quality of life and depressive symptoms in Chinese Hong Kong older adults. Methods and analyses An observational study of the associations of measures of the physical and social neighbourhood environment, and psychosocial factors, with physical activity, quality of life and depressive symptoms in 900 Hong Kong older adults aged 65+ years is being conducted in 2012–2016. The study involves two assessments taken 6 months apart. Neighbourhood walkability and access to destinations are objectively measured using Geographic Information Systems and environmental audits. Demographics, socioeconomic status, walking for different purposes, perceived neighbourhood and home environments, psychosocial factors, health status, social networks, depressive symptoms and quality of life are being assessed using validated interviewer-administered self-report measures and medical records. Physical functionality is being assessed using the Short Physical Performance Battery. Physical activity and sedentary behaviours are also being objectively measured in approximately 45% of participants using accelerometers over a week. Physical activity, sedentary behaviours, quality of life and depressive symptoms are being assessed twice (6 months apart) to examine seasonality effects on behaviours and their associations with quality of life and depressive symptoms. Ethics and dissemination The study received ethical approval from the University of Hong Kong Human Research Ethics Committee for Non-Clinical Faculties (EA270211) and the Department

    This study examined the impact of inattention and hyperactivity symptoms in children and mothers, opposition problems in children, maternal depression, and perceived family support on the quality of life (QOL) of mothers. Mothers of children in one elementary school were contacted. The relationship between sociodemographic variables, the levels of inattention and hyperactivity symptoms in children and mothers, oppositional symptoms in children, maternal depression, perceived family support, and maternal QOL were examined. Three hundred and eighty-two participants were included in this study. Consistent factors related to the mother's QOL in the four domains were maternal depression, perceived family support, and housing status after controlling for several family, maternal, and child variables. Maternal QOL was more related to her own and family factors including maternal inattention, hyperactivity and depression symptoms, perceived family support, and housing status, instead of parent-rated inattention and hyperactivity symptoms of the child. Screening for maternal inattention, hyperactivity and depression symptoms, and mental health services for these mothers are warranted based on these findings. PMID:25476102

    The purpose of this study was to determine the factors explaining changes in the generic quality of life among patients with Menière's disorder (MD) and to evaluate the EuroQol 5D (EQ-5D) quality-of-life measures. A questionnaire focusing on symptoms and disabilities caused by MD was collected from 726 individuals. General health-related quality of life (EQ-5D) was evaluated using the time trade-off (TTO) and visual-analogue scale (VAS). Personal traits were measured with the sense of coherence. The TTO-VAS score difference was modeled with activity limitations, participation restrictions, attitudes, and symptoms. For TTO as the outcome measure, one symptom-based, three attitude-based, one activity limitation, and one participation restriction item explained 43% of the variability. For VAS, six attitude-based, one symptom-based, three activity limitations, and one participation restriction item explained 43% of the variability of the data. The correlation between TTO and VAS (r=0.515, P<0.001) explained only 27% of the variance. The difference between TTO and VAS was reflected in attitudes towards the illness. The model explained 10% of the variability in the VAS and TTO difference. There was a disease duration effect in the TTO-VAS difference. In conclusion, a symptom-based model combined with disabilities provided a good description of general quality of life in MD. The TTO-based and VAS-based evaluation explained somewhat different aspects of MD. The difference between TTO and VAS could be described as an attitude toward the ailment. Evaluation of disabilities and the difference in TTO and VAS can be used to guide the rehabilitation to promote attitude change. PMID:22872300

    Purpose: To evaluate whether the daily intake of synbiotics interferes in radiation-induced acute proctitis symptoms and in quality of life in patients with prostate cancer. Methods and Materials: Twenty patients who underwent 3-dimensional conformal radiation therapy for prostate cancer were randomized to intake either a synbiotic powder containing Lactobacillus reuteri 10{sup 8} colony-forming units and 4.3 g of soluble fiber (Nestlé) or placebo. The questionnaire EORTC QLQ-PRT23 was applied before the beginning of radiation therapy and in every week for the first 4 weeks of treatment. The sum of both the complete (proctitis symptoms plus quality of life) and partial (proctitis symptoms) scores of the EORTC QLQ-PRT23 (European Organization for Research and Treatment of Cancer Quality of Life Module for Proctitis–23 items) questionnaire were the main endpoints. Results: This pilot study showed that the complete questionnaire score (median [range]) was higher in the second (23 [21-30] vs 26.5 [22-34], P<.05) and third (23 [21-32] vs 27.5 [24-33], P<.01) weeks in the placebo group. Proctitis symptoms were highest scored in the placebo group in both the second (19.5 [16-25]) and third (19 [17-24]) weeks than in the synbiotic group (week 2: 16.5 [15-20], P<.05; week 3: 17 [15-23], P<.01). In both scores the placebo group had a significantly higher result (P<.01) than the synbiotic group (repeated-measures analysis of variance). Conclusions: Synbiotics reduce proctitis symptoms and improve quality of life in radiation-induced acute proctitis during radiation therapy for prostate cancer.

    Objective Studies that have investigated quality of life (QoL) in eating disorders (EDs) have been focussed on the impact of the ED on QoL and little is known regarding the possible reciprocal impact of QoL on EDs. The aim of this study was to provide a first-time investigation of possible bidirectional relationships between EDs and both health-related QoL (HRQoL) and psychological distress (PD). Method Structural equation modeling was applied to longitudinal data collected from a community sample of Australian women (N = 828) surveyed at baseline, five annual follow-ups, and again after nine years. Participants reported height and weight (from which body mass index, BMI, was calculated) and completed measures of ED symptoms (Eating Disorder Examination Questionnaire), HRQoL (12-item Medical Outcomes Study Short Form), and PD (Kessler Psychological Distress Scale). Results Overall, evidence was found for a bidirectional relationship, whereby ED symptoms predicted reduced HRQoL and greater PD over time, while lower levels of HRQoL and greater PD in turn predicted increased levels of ED symptoms. These relationships were stable, observable within 12 months, and remained observable over a time period of at least four years. However, also observed were some inconsistent findings where ED symptoms predicted a short term (one year) improvement in mental HRQoL. This short term boost was not sustained at longer follow-ups. Conclusions Not only do ED symptoms impact on HRQoL and PD, but perceived poor HRQoL and PD also contribute to ED symptom development or exacerbation. This supports a movement away from symptom-centric approaches whereby HRQoL is conceptualized as a passive outcome expected to be rectified by addressing ED symptoms. Improvement in QoL and PD might rather be viewed as targets to be pursued in their own right under broader approaches in the treatment of EDs. PMID:25812047

    Chemotherapy for platinum-resistant/refractory ovarian cancer is motivated by the hope of benefit. We sought to determine the relationships between: (a) trait hope, expectation of symptom benefit from chemotherapy, and anxiety and depression; (b) hope and perceived efficacy of chemotherapy; and (c) unfulfilled hope (where expectations for benefit are not fulfilled) and depression. Methods. Adult patients enrolled within stage 1 of the Gynecologic Cancer Intergroup Symptom Benefit Study were included. Patient. Reported outcomes were collected from 126 women with predominantly platinum-resistant ovarian cancer at baseline, prior to the first four treatment cycles (12-16 weeks), and four weeks after completing chemotherapy or at disease progression, whichever came first. Associations were assessed with Spearman rank correlation coefficient (r) and odds ratio. Results. Trait hope and expectation of symptom benefit from chemotherapy were weakly correlated with each other (r = 0.25). Trait hope, but not expectation of symptom benefit, was negatively correlated with anxiety (r = -0.43) and depression (r = -0.50). The smaller the discrepancy between perceived and expected symptom benefit, the less likely the patient was to have scores indicative of depression (odds ratio: 0.68; 95% confidence interval: 0.49-0.96; p = .026). Conclusion. Trait hope and expectation of symptom benefit from chemotherapy appear to be distinct and independent of the aspects of quality of life and scores for depression. Hope did not appear to affect perceived efficacy of chemotherapy in alleviating symptoms, but women whose expectation of symptom benefit from chemotherapy was not fulfilled were more likely to have scores indicative of depression. It may be preferable to encourage hope toward achievable goals rather than toward benefits from chemotherapy. PMID:24107972

    Background Nocturia has been proven to have a negative impact on the quality of life and sleep quality in general elderly population. However, there are limited studies on the quantitative effect of nocturia on sleep quality and daytime dysfunction, specifically in patients with lower urinary tract symptoms. Patients and methods During March 1, 2015 to December 31, 2015, a total of 728 patients who visited our urology department due to voiding dysfunction and experienced nocturia at least once per night were enrolled. Three questionnaires were administered to them after obtaining their written consents. Pittsburgh Sleep Quality Index (PSQI) questionnaire, Epworth Sleepiness Scale (ESS) questionnaire, and International Prostate Symptom Score (IPSS) questionnaire were applied to evaluate their sleep quality, daytime dysfunction, and voiding problems, respectively. Statistical analysis of the impact of nocturia on sleep quality and daytime dysfunction was performed. Results The mean age of patients was 61 years, with a male-to-female ratio of 2.7. The mean nocturia number was 3.03. The IPSS, PSQI, and ESS scores were 17.56, 8.35, and 8.22, respectively. The nocturia number increased with age and was significantly correlated to ESS score (daytime dysfunction) and PSQI total score (sleep quality) in overall group. Among subgroups divided by age and sex, there was a significant correlation between nocturia number and daytime dysfunction in male patients or patients younger than 65 years. Conclusion In patients with lower urinary tract symptoms, nocturia number increased with age and was significantly correlated with poor sleep quality. Nocturia plays an important role in patients younger than 65 years in daytime dysfunction. PMID:27418814

    The feasibility and acceptability of computerized screening and patient-reported outcome measures have been demonstrated in the literature. However, patient-centered management of health information entails two challenges: gathering and presenting data using “patient-tailored” methods and supporting “patient-control” of health information. The design and development of many symptom and quality-of-life information systems have not included opportunities for systematically collecting and analyzing user input. As part of a larger clinical trial, the Electronic Self-Report Assessment for Cancer–II project, participatory design approaches were used to build and test new features and interfaces for patient/caregiver users. The research questions centered on patient/caregiver preferences with regard to the following: (a) content, (b) user interface needs, (c) patient-oriented summary, and (d) patient-controlled sharing of information with family, caregivers, and clinicians. Mixed methods were used with an emphasis on qualitative approaches; focus groups and individual usability tests were the primary research methods. Focus group data were content analyzed, while individual usability sessions were assessed with both qualitative and quantitative methods. We identified 12 key patient/caregiver preferences through focus groups with 6 participants. We implemented seven of these preferences during the iterative design process. We deferred development for some of the preferences due to resource constraints. During individual usability testing (n = 8), we were able to identify 65 usability issues ranging from minor user confusion to critical errors that blocked task completion. The participatory development model that we used led to features and design revisions that were patient centered. We are currently evaluating new approaches for the application interface and for future research pathways. We encourage other researchers to adopt user-centered design approaches

    To determine the prospective association between health-related control beliefs, quality of life (QOL), depression symptoms, and health behaviours in coronary artery bypass graft (CABG) patients 6-8 weeks following surgery. 149 patients who were undergoing planned CABG surgery were recruited. Patients completed questionnaires measuring health related personal control, treatment control, depression symptoms, QOL, and health behaviours prior to and 6-8 weeks after surgery. Higher levels of health-related personal control predicted better QOL, and lower levels of depression symptoms, but not adherence to medication, cardiac rehabilitation attendance, or physical activity. These results were independent of demographic, behavioural, and clinical covariates. Treatment control was not associated with any outcome. These results suggest that perceived health-related personal control is associated with key aspects of short-term recovery from CABG surgery. Targeted interventions aimed at improving perceptions of health-related personal control may improve health outcomes in this cardiac population. PMID:26341356

  12. Symptoms induced by environmental irritants and health-related quality of life in patients with chronic cough - A cross-sectional study

    PubMed Central

    2011-01-01

    Background Chronic cough is a common condition, but some patients have no evident medical explanation for their symptoms. A group of patients has been identified, characterized by upper and lower airway symptoms triggered by chemicals and scents, and heightened cough sensitivity to inhaled capsaicin. Chronic cough is usually a prominent symptom in these patients, and it has been suggested that they suffer from sensory hyperreactivity. Our main aim was to analyse, in a group of patients with chronic cough, the presence of symptoms induced by environmental factors such as chemicals, scents, and cold air, and to measure the social and emotional influences of these symptoms in relation to quality of life. A second aim was to pilot-test a Swedish translation of a cough-specific questionnaire. Methods A total of 119 patients with chronic cough were asked to answer three different questionnaires: a local symptom questionnaire, the Chemical Sensitivity Scale for Sensory Hyperreactivity (CSS-SHR), and the Nottingham Health Profile (NHP). In addition, a Swedish version of the Hull Airway Reflux Questionnaire (HARQ) was developed and answered by a subgroup of patients and healthy controls. Results Sixty-two patients (52%) with mean cough duration of 10.6 years answered the local symptom questionnaire, the CSS-SHR, and the NHP. Of these, 39 (63%) claimed to have cough and other symptoms induced by chemicals and scents. Compared to population-based findings, the patients scored higher on the CSS-SHR, and the CSS-SHR score was significantly higher among chemical-sensitive individuals (p < 0.001). The NHP showed that the patients had a significantly reduced quality of life, which was most pronounced among chemical-sensitive individuals. The 31 patients who answered the HARQ had significantly higher scores (p < 0.0001) than 59 healthy controls. Conclusions Among patients with chronic cough, a majority claimed that environmental factors induced coughing. Both the CSS-SHR and the

    Introduction Sick building syndrome (SBS) includes general, mucosal and skin symptoms. It is typically associated with an individual's place of work or residence. The aim of this study was to explore the effect of traffic exposure on SBS symptoms in Beijing, China. Methods From January to May, 2011, recruitment occurred at kindergartens in 11 districts in Beijing. Self-administered questionnaires were distributed by teachers to legal guardians of children and then returned to teachers. The questionnaire asked them to recall the presence of 12 SBS symptoms from the previous three months. Living near a highway or main road (within 200 meters) was used as a proxy for traffic exposure. Multivariable logistic regression was used to test the association between traffic exposure and a higher number of SBS symptoms, controlling for key covariates. Results There were 5487 valid questionnaires (65.0% response rate). Univariate analysis showed that living near a main road or highway (OR = 1.40), female gender (OR = 1.44), and environmental tobacco smoking (ETS) (OR = 1.13) were significant risk factors for general symptoms. Grandparent’s generation (OR = 0.32) and home ownership (owner vs. renter) (OR = 0.89) were significant protective factors. The adjusted odds ratio (aOR) for the association between living close to a highway and general symptoms remained significant in the multivariable model (aOR = 1.39; 95% CI = 1.21: 1.59). ORs and aORs were similar for mucosal and skin symptoms. Conclusions This study found traffic exposure to be significantly associated with SBS symptoms. This finding is consistent with current literature that indicates an association between adverse health effects and living near highway or main road. PMID:26086248

    Abstract Background: People with chronic heart failure (HF) suffer from numerous symptoms that worsen quality of life. The CASA (Collaborative Care to Alleviate Symptoms and Adjust to Illness) intervention was designed to improve symptoms and quality of life by integrating palliative and psychosocial care into chronic care. Objective: Our aim was to determine the feasibility and acceptability of CASA and identify necessary improvements. Methods: We conducted a prospective mixed-methods pilot trial. The CASA intervention included (1) nurse phone visits involving structured symptom assessments and guidelines to alleviate breathlessness, fatigue, pain, or depression; (2) structured phone counseling targeting adjustment to illness and depression if present; and (3) weekly team meetings with a palliative care specialist, cardiologist, and primary care physician focused on medical recommendations to primary care providers (PCPs, physician or nurse practioners) to improve symptoms. Study subjects were outpatients with chronic HF from a Veteran's Affairs hospital (n=15) and a university hospital (n=2). Measurements included feasibility (cohort retention rate, medical recommendation implementation rate, missing data, quality of care) and acceptability (an end-of-study semi-structured participant interview). Results: Participants were male with a median age of 63 years. One withdrew early and there were <5% missing data. Overall, 85% of 87 collaborative care team medical recommendations were implemented. All participants who screened positive for depression were either treated for depression or thought to not have a depressive disorder. In the qualitative interviews, patients reported a positive experience and provided several constructive critiques. Conclusions: The CASA intervention was feasible based on participant enrollment, cohort retention, implementation of medical recommendations, minimal missing data, and acceptability. Several intervention changes were made based

    Quality of life (QoL) in patients with myelofibrosis (MF) is severely compromised by severe constitutional symptoms (i.e. fatigue, night sweats, fever, weight loss), pruritus, and symptoms from frequently massive hepatosplenomegaly. Given that no current instrument of patient reported outcomes (PRO) exists that covers the unique spectrum of symptomatology seen in MF patients, we sought to develop a new PRO instrument for MF patients for use in therapeutic clinical trials. Utilizing data from an international Internet-based survey of 458 patients with MF we created a 20-item instrument (MFSAF: Myelofibrosis Symptom Assessment Form) which measures the symptoms reported by >10% of MF patients and includes a measure of QoL. We subsequently validated the MFSAF in a prospective trial of MF patients involving patient and provider feedback, as well as comparison to other validated instruments used in cancer patients. The MFSAF results were highly correlated with other instruments, judged comprehensive and understandable by patients, and should be considered for evaluation of MF symptoms in therapeutic trials.

    Preterm birth may represent a traumatic situation for both parents and a stressful situation for the infant, potentially leading to difficulties in mother-infant relationships. This study aimed to investigate the impact of an early intervention on maternal posttraumatic stress symptoms, and on the quality of mother-infant interactions, in a sample of very preterm infants and their mothers. Half of the very preterm infants involved in the study (n=26) were randomly assigned to a 3-step early intervention program (at 33 and 42 weeks after conception and at 4 months' corrected age). Both groups of preterm infants (with and without intervention) were compared to a group of full-term infants. The impact of the intervention on maternal posttraumatic stress symptoms was assessed 42 weeks after conception and when the infants were 4 and 12 months of age. The impact of the intervention on the quality of mother-infant interactions was assessed when the infants were 4 months old. Results showed a lowering of mothers' posttraumatic stress symptoms between 42 weeks and 12 months in the group of preterm infants who received the intervention. Moreover, an enhancement in maternal sensitivity and infant cooperation during interactions was found at 4 months in the group with intervention. In the case of a preterm birth, an early intervention aimed at enhancing the quality of the mother-infant relationship can help to alleviate maternal post-traumatic stress symptoms and may have a positive impact on the quality of mother-infant interactions.

    Rationale: Inflammation is associated with symptoms in many chronic illnesses; however, this link has not been established in pulmonary arterial hypertension. Objectives: The objective of this study was to investigate the association between inflammatory markers and quality of life–related symptoms in patients with pulmonary arterial hypertension. We hypothesized that higher circulating IL-6 and tumor necrosis factor-α levels would be associated with worse quality of life–related symptoms. Methods: We performed a secondary analysis using baseline and 3-month assessments of 62 subjects in a clinical trial of aspirin and simvastatin to determine the association between plasma IL-6 and tumor necrosis factor-α levels and the Medical Outcomes Study Short Form-36 subscales (pain, vitality, mental health). Measurements and Main Results: The mean age was 49.7 ± 13.4 years; 87% were female. Higher IL-6 levels were significantly associated with lower Medical Outcomes Study Short Form-36 subscale scores, indicating worse bodily pain, vitality, and mental health (all P < 0.01). Higher tumor necrosis factor-α levels were significantly associated with increased bodily pain, but better mental health scores. Conclusions: IL-6 and tumor necrosis factor-α levels are associated with certain quality of life domains in patients with pulmonary arterial hypertension.

    Background In a randomized phase III study, trametinib prolonged progression-free survival and improved overall survival versus chemotherapy in patients with BRAF V600 mutation-positive melanoma. Patients and methods Patients' quality of life (QOL) was assessed at baseline and follow-up visits using the European Organisation for Research and Treatment of Cancer Core QOL questionnaire. Results In the primary efficacy population (BRAF V600E+, no brain metastases) from baseline to weeks 6 and 12, patients' global health status scores worsened by 4–5 points with chemotherapy but improved by 2–3 points with trametinib. Rapid and substantive reductions in QOL functionality (e.g. role functioning, 8–11 points at weeks 6 and 12) and symptom exacerbation (e.g. fatigue, 4–8 points; nausea and vomiting, 5 points, both at weeks 6 and 12) were observed in chemotherapy-treated patients. In contrast, trametinib-treated patients reported small improvements or slight worsening from baseline at week 12, depending on the functional dimension and symptom. The mean symptom-scale scores for chemotherapy-treated patients increased from baseline (symptoms worsened) for seven of eight symptoms at week 6 (except insomnia) and six of eight symptoms at week 12 (except dyspnea and insomnia). In contrast, at weeks 6 and 12, the mean symptom-scale scores for trametinib decreased from baseline (symptoms improved) for pain (11–12 points), insomnia (10–12 points), and appetite loss (1–5 points), whereas those for diarrhea worsened (15–16 points). Mixed-model repeated-measures analyses showed significant (P < 0.05) and/or clinically meaningful improvements (small to moderate) from baseline in favor of trametinib for global health; physical, role, and social functioning; fatigue; pain; insomnia; nausea and vomiting; constipation; dyspnea; and appetite at weeks 6 and/or 12. QOL results for the intent-to-treat population were consistent. Conclusions This first QOL assessment for a MEK

    We report on the R&D effort in the design and construction of a large size Gas Electron Multiplier (GEM) for the Proton Polarimeter Back Tracker (BT) of the Super Bigbite Spectrometer (SBS) in Hall A at Thomas Jefferson National Laboratory (JLab). The SBS BT GEM trackers consist of two sets of five large GEM chambers of size 60×200 cm2. The GEM chamber is a vertical stack of four GEM modules, each with an active area of 60×50 cm2. We have built and tested several prototypes and the construction of GEM modules for SBS BT is ongoing. We describe in this paper the design and construction of the GEM module prototype as well as the preliminary results on performance from tests carried out in our detector lab and during test beam at Fermi National Laboratory (Fermilab).

    We report Fermi-LAT observations of the radio-loud AGN SBS 0846+513 (z=0.5835), optically classified as a Narrow-Line Seyfert 1 galaxy, together with new and archival radio-to-X-ray data. The source was not active at ?-ray energies during the first two years of Fermi operation. A significant increase in activity was observed during 2010 October-2011 August. In particular a strong gamma-ray flare was observed in 2011 June reaching an isotropic ?-ray luminosity (0.1-300 GeV) of 1.0×10(sup 48) erg s(sup -1), comparable to that of the brightest flat spectrum radio quasars, and showing spectral evolution in gamma rays. An apparent superluminal velocity of (8.2+/-1.5)c in the jet was inferred from 2011-2012 VLBA images, suggesting the presence of a highly relativistic jet. Both the power released by this object during the flaring activity and the apparent superluminal velocity are strong indications of the presence of a relativistic jet as powerful as those of blazars. In addition, variability and spectral properties in radio and gamma-ray bands indicate blazar-like behaviour, suggesting that, except for some distinct optical characteristics, SBS 0846+513 could be considered as a young blazar at the low end of the blazar's black hole mass distribution.

    Presented are orbit and attitude determination results from the launch of Satellite Business Systems (SBS)-5 satellite on September 8, 1988 by Arianespace. SBS-5 is a (HS-376) spin stabilized spacecraft. The launch vehicle injected the spacecraft into a low inclination transfer orbit. Apogee motor firing (AMF) attitude was achieved with trim maneuvers. An apogee kick motor placed the spacecraft into drift orbit. Postburn, reorientation and spindown maneuvers were performed during the next 25 hours. The spacecraft was on-station 19 days later. The orbit and attitude were determined by both an extended Kalman filter and a weighted least squares batch processor. Although the orbit inclination was low and the launch was near equinox, post-AMF analysis indicated an attitude declination error of 0.034 deg., resulting in a saving of 8.5 pounds of fuel. The AMF velocity error was 0.4 percent below nominal. The post-AMF drift rate was determined with the filter only 2.5 hours after motor firing. The filter was used to monitor and retarget the reorientation to orbit normal in real time.

    The methods of panoramic (3D) spectroscopy are used by us in a detailed study of galaxies with ongoing star formation chosen from among objects in seven selected fields of the Second Byurakan Survey (SBS). This article deals with the irregular galaxy SBS 1202 + 583, which our classification scheme identifies as being in a continuous phase of star formation. Observations were made with the panoramic spectrographs MPFS at the 6-m telescope of the Special Astrophysical Observatory (SAO) of the Russian Academy of Sciences and VAGR at the 2.6-m telescope of the Byurakan Astrophysical Observatory (BAO) in Armenia. The data are used to construct maps of the radiative fluxes in the continuum and various emission lines. Special attention is devoted to analyzing the emission in the H α hydrogen recombination line and in the forbidden low-ionization doublets of nitrogen [NII] λλ6548, 6583 and sulfur [SII] λλ6716, 6731, and the ratios of the intensities of the forbidden lines to H α. The observable characteristics (size, H α fluxes, etc.) of nine HII regions are studied. The estimated current rates of star formation in the individual HII regions based on the H α fluxes lie within the range of 0.3-1.2⨀ M /year. The dependence of the ratio of the intensities of the emission in these above mentioned forbidden doublets on the rate of star formation in the HII regions is found.

    Background Symptoms of heartburn has an impact on health-related quality of life (HRQL). When a questionnaire is translated into a new language, a linguistic validation is necessary but not sufficient unless the psychometric characteristics have been verified. The aim is to document the psychometric characteristics of the German translation of the Gastrointestinal Symptom Rating Scale (GSRS) and Quality of Life in Reflux and Dyspepsia (QOLRAD) questionnaire. Methods 142 patients with symptoms of heartburn (Age: M = 47.5, ± 14.6; Males = 44.4%) completed the German translation of GSRS, the QOLRAD, the Short-Form-36 (SF-36) and the Hospital Anxiety and Depression (HAD) scale. Results The internal consistency reliability of GSRS ranged from 0.53–0.91 and of QOLRAD from 0.90–0.94, respectively. The test-retest reliability of GSRS ranged from 0.49–0.73 and of QOLRAD from 0.70–0.84. The relevant domains of the GSRS and QOLRAD domain scores significantly correlated. GSRS domains of Abdominal Pain and Constipation correlated (negatively) with most of the domains of the SF-36. The relevant QOLRAD domains significantly correlated with all SF-36 domains. Conclusions The psychometric characteristics of the German translation of GSRS and QOLRAD were found to be good, with satisfactory reliability and validity. The reliability of the GSRS Abdominal Pain domain was moderate. PMID:14613560

    Ethnic/racial discrimination has persistent negative implications for both physical and mental health. The current study employs a risk and resilience framework to explore the joint effects of ethnic/racial discrimination and sleep disturbance on psychosocial outcomes among adolescents. In a sample of 146 minority and White adolescents (70% female), changes in depressive symptoms, anxiety, and self-esteem over 3 years are explored using growth curve models. Regardless of ethnic background, adolescents reporting high levels of ethnic/racial discrimination and poor sleep also reported a corresponding increase in depressive symptoms and lower levels of self-esteem over time. Adolescents reporting all other combinations of sleep quality and ethnic/racial discrimination reported more positive adjustment over time. The joint effects of sleep and ethnic/racial discrimination on adolescent psychosocial development are discussed. PMID:24682960

    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. PMID:19999673

    Purpose: To examine the impact of lower urinary tract symptoms (LUTS) on health-related quality of life (HRQoL) in Korean men aged ≥40 years. Methods: A population-based, cross-sectional door-to-door survey was conducted among men aged ≥40 years. Individuals with LUTS were defined as men reporting at least one LUTS using 2002 International Continence Society definitions. Structuredquestionnaires were used to assess several dimensions of HRQoL, including generic health status (EuroQoL-five-dimensions questionnaire), work productivity (work productivity and activity impairment questionnaire), depressive symptoms (center for epidemiologic studies depression scale), and sexual health (sexual satisfaction and erectile dysfunction). The impact of LUTS was assessed by comparing several dimensions of HRQoL among men with and without LUTS. Results: Of the 1,842 participants, 1,536 (83.4%) reported having at least one LUTS. The prevalence of LUTS increased with age (78.3% among those aged 40–49 years to 89.6% among those aged 60 years or older). Those with LUTS reported a significantlylower level of generic health status and worse work productivity compared with those without LUTS. Significantly more individuals with LUTS reported having a higher level of major depressive symptoms compared with those without LUTS.Those with LUTS reported worse sexual activity and enjoyment, and were significantly more likely to have erectile dysfunction than those without LUTS. Conclusions: LUTS seem to have a substantial impact on several dimensions of HRQoL in Korean men aged ≥40 years. PMID:26126442

    Aim Undergoing diagnostic evaluation for possible cancer can affect health-related quality of life (HRQoL). The aims of this study were to examine the HRQoL in patients undergoing a diagnostic evaluation for possible cancer due to non-specific symptoms and further to investigate the impact of socio-demographic and medical factors associated with HRQoL at the time of diagnosis. Methods This was a prospective, multicenter survey study that included patients who were referred for a diagnostic evaluation due to non-specific cancer symptoms. Participants completed the EORTC-QLQ-C30 quality of life scale before and after completing the diagnostic evaluation. The baseline and follow-up EORTC-QLQ-C30 scores were compared with reference populations. The impact of socio-demographic and medical factors on HRQoL at follow-up was explored by bootstrapped multivariate linear regression. Results A total of 838 patients participated in the study; 680 (81%) also completed follow-up. Twenty-two percent of the patients received a cancer diagnosis at the end of follow-up. Patients presented initially with a high burden of symptoms, less role and emotional functioning and a lower global health/QoL. Most domains improved after diagnosis and no clinically important difference between baseline and follow-up scores was found. Patients reported effects on HRQoL both at baseline and at follow-up compared with the Danish reference population and had similar scores as a cancer reference population. Co-morbidity, being unemployed and receiving a cancer diagnosis had the greatest effect on HRQoL around the time of diagnosis. Conclusions Patients with non-specific symptoms reported an affected HRQoL while undergoing a diagnostic evaluation for possible cancer. Morbidity, being unemployed and receiving a cancer diagnosis had the greatest effect on HRQoL around the time of diagnosis. PMID:26840866

    Breast cancer is the most common form of cancer amongst women. Women with breast cancer frequently consult dietitians for advice, and increasingly advice on complementary alternative medicines (CAM). The aim of this systematic review was to evaluate evidence of CAM administered orally on cancer-related outcomes. Databases were searched for studies recruiting women with a history of breast cancer reporting on the use of CAM administered orally as tablets, capsules, powders, and liquids for any 1 or more of the following: alleviation of cancer-related symptoms and treatment side effects, improvement to quality of life, physical and emotional wellbeing, survival, and mortality. Twenty-two studies were identified as meeting the inclusion criteria. Ten CAM categories were established with no more than 4 articles published in each category. Although the evidence is of varying quality there is some data to support that guarana and Ganoderma lucidum may improve fatigue, whereas glutamine may also be effective in improving oral mucositis symptoms. Overall, the current available evidence is inconclusive to make definitive recommendations regarding the effectiveness for individuals' use of CAM in women with breast cancer. Further high-quality randomized controlled trials exploring safety, toxicity, and other potential adverse effects of CAM are required. PMID:25811312

    Objectives. To evaluate the effectiveness of Baduanjin Qigong exercise on sleep, fatigue, anxiety, and depressive symptoms in chronic fatigue syndrome- (CFS-) like illness and to determine the dose-response relationship. Methods. One hundred fifty participants with CFS-like illness (mean age = 39.0, SD = 7.9) were randomly assigned to Qigong and waitlist. Sixteen 1.5-hour Qigong lessons were arranged over 9 consecutive weeks. Pittsburgh Sleep Quality Index (PSQI), Chalder Fatigue Scale (ChFS), and Hospital Anxiety and Depression Scale (HADS) were assessed at baseline, immediate posttreatment, and 3-month posttreatment. The amount of Qigong self-practice was assessed by self-report. Results. Repeated measures analyses of covariance showed a marginally nonsignificant (P = 0.064) group by time interaction in the PSQI total score, but it was significant for the "subjective sleep quality" and "sleep latency" items, favoring Qigong exercise. Improvement in "subjective sleep quality" was maintained at 3-month posttreatment. Significant group by time interaction was also detected for the ChFS and HADS anxiety and depression scores. The number of Qigong lessons attended and the amount of Qigong self-practice were significantly associated with sleep, fatigue, anxiety, and depressive symptom improvement. Conclusion. Baduanjin Qigong was an efficacious and acceptable treatment for sleep disturbance in CFS-like illness. This trial is registered with Hong Kong Clinical Trial Register: HKCTR-1380. PMID:25610473

    Recent experiments on OMEGA have studied stimulated Brillouin backscatter in preformed long-scale-length plasmas for both single and multiple interaction beams. Scattered light intensities and spectra were obtained for a variety of irradiation conditions. Ion Landau damping is estimated to be sufficiently strong in these plasmas that the locally driven approximation for the ion-sound wave response can be applied. The linear SBS gain coefficient can then obtained by integrating the coupled wave equations for the incident and scattered light throughout the underdense plasma corona. Using density, velocity, and temperature profiles obtained from the two-dimensional Eulerian hydrocode SAGE, we have calculated as a function of wavelength the SBS gain coefficients to be expected in these experiments. Comparison with the observed scattering levels and spectra allows several conclusions to be drawn regarding the SBS process in these plasmas. Most saliently, the scattering appears to be dominated by SBS occurring in hot spots, and plasma velocity profiles have a strong influence on the location and level of scattering. Generally good agreement is found between the observations and the calculations, though some discrepancies remain, particularly in the absorption levels and spectral shifts.

    Using the 100 office-building Building Assessment Survey and Evaluation (BASE) Study dataset, we performed multivariate logistic regression analyses to quantify the associations between indoor minus outdoor CO{sub 2} (dCO{sub 2}) concentrations and mucous membrane (MM) and lower respiratory system (Lresp) Sick Building Syndrome (SBS) symptoms, adjusting for age, sex, smoking status, presence of carpet in workspace, thermal exposure, relative humidity, and a marker for entrained automobile exhaust. Using principal components analysis we identified a number of possible sources of 73 measured volatile organic compounds in the office buildings, and assessed the impact of these VOCs on the probability of presenting the SBS symptoms. Additionally we included analysis adjusting for the risks for predisposition of having SBS symptoms associated with the allergic, asthmatic, and environmentally sensitive subpopulations within the office buildings. Adjusted odds ratios (ORs) for statistically significant, dose-dependant associations (p<0.05) for dry eyes, sore throat, nose/sinus congestion, and wheeze symptoms with 100-ppm increases in dCO{sub 2} ranged from 1.1 to 1.2. These results suggest that increases in the ventilation rates per person among typical office buildings will, on average significantly reduce the prevalence of several SBS symptoms, up to 80%, even when these buildings meet the existing ASHRAE ventilation standards for office buildings. VOC sources were observed to play an role in direct association with mucous membrane and lower respiratory irritation, and possibly to be indirectly involved in indoor chemical reactions with ozone that produce irritating compounds associated with SBS symptoms. O-xylene, possibly emitted from furniture coatings was associated with shortness of breath (OR at the maximum concentration = 8, p < 0.05). The environmental sensitivities of a large subset of the office building population add to the overall risk of SBS symptoms (ORs

    2014-08-25

    We present a comprehensive analysis of the technique of Longitudinal-Mode-Filling (LMF) to reduce Stimulated Brillouin Scattering (SBS) limitations in Ytterbium Doped Fibre Amplifiers (YDFA), for the generation of nanosecond, temporally shaped pulses. A basic Master-Oscillator-Power-Amplifier (MOPA) system, comprising an output YDFA with 10 µm-core active fibre, is experienced for benchmarking purposes. Input pulse-shaping is operated thanks to direct current modulation in highly multimode laser-diode seeds, either based on the use of Distributed Feed-Back (DFB) or of a Fibre Bragg Grating (FBG). These seeds enable wavelength control. We verify the effectiveness of the combination of LMF, with appropriate mode spacing, in combination with natural chirp effects from the seed to control the SBS threshold in a broad range of output energies, from a few to some tens of µJ. These variations are discussed versus all the parameters of the laser system. In accordance with the proposal of a couple of basic principles and with the addition of gain saturation effects along the active fibre, we develop a full-vectorial numerical model. Fine fits between experimental results and theoretical expectations are demonstrated. The only limitation of the technique arises from broadband beating noise, which is analysed thanks to a simplified, but fully representative description to discuss the signal-to-noise ratio of the amplified pulses. This provides efficient tools for application to the design of robust and cost-effective MOPAs, aiming to the generation of finely shaped and energetic nanosecond pulses without the need for any additional electro-optics.

    This study explored the mediating role of sleep in the relationship between personality traits and depressive symptoms in a group of community-dwelling men and women (Mage = 57.92, SD = 4.00). Participants completed the short form NEO Five Factor Inventory (NEO-FFI), Pittsburgh Sleep Quality Index (PSQI), and the Center for Epidemiologic Studies Depression Scale (CES-D). High neuroticism and low conscientiousness was associated with poor sleep, as well as greater depressive symptom severity. Partial indirect mediation effects were found between personality traits (i.e., neuroticism and conscientiousness) and depressive symptoms through self-report sleep measures. An alternative model was also explored, entering depression as the mediator; however a smaller portion of the variance was explained by this model, compared with the hypothesized model. The current study provides preliminary information regarding the mechanisms that influence the relationship between personality traits, sleep, and depression among a group of community-dwelling middle-aged adults. Implications and future directions are discussed. PMID:27285159

Partial indirect mediation effects were found between personality traits (i.e., neuroticism and conscientiousness) and depressive symptoms through self-report sleep measures. An alternative model was also explored, entering depression as the mediator; however a smaller portion of the variance was explained by this model, compared with the hypothesized model. The current study provides preliminary information regarding the mechanisms that influence the relationship between personality traits, sleep, and depression among a group of community-dwelling middle-aged adults. Implications and future directions are discussed. PMID:27285159

    The prevalence of non-motor symptoms (NMS) in Parkinson's Disease (PD) has varied between studies. Their interrelation isn't totally understood. Also, the relative importance of each symptom, regarding its impact on activities of daily living (ADL) and health related quality of life (HRQL), remains debatable. We assessed all PD patients attending a Portuguese tertiary movement disorders center during one year (n = 134), with ADL, HRQL and other clinical scales approved for identifying the most relevant NMS in PD. All patients had at least one NMS. Sleep/fatigue, affect/cognition, attention/memory were the most frequent complaints, and their prevalence, above 80%, was higher than in most studies. There were significantly correlations between: sleepiness, psychosis and cognition; gastrointestinal, cardiovascular symptoms and pain; depression and apathy; anxiety and insomnia; olfaction, weight and hyperhidrosis. Depression/apathy exerted the strongest influence on HRQL and non-tremor motor dysfunction on ADL. Compared to studies in other countries, we found a higher prevalence of NMS, which could be specific of this population. The interrelation between NMS could be related to degeneration of different brain structures. NMS exert a stronger influence than MS in HRQL, which should be taken in account regarding treatment options. PMID:27573215

    Background. Female Parkinson's disease (PD) patients seem to experience not only more severe motor complications and postural instability but also more pronounced depression, anxiety, pain, and sleep disturbances. Objective. The aim of the present study was to evaluate the role of sex as a possible independent predictor of HRQoL in PD. Methods. In this cross-sectional study, 621 consecutive patients treated at the University of Pécs were enrolled. Severity of PD symptoms was assessed by MDS-UPDRS, UDysRS, Non-Motor Symptoms Scale, PDSS-2, Hamilton Anxiety Scale, Montgomery-Asberg Depression Rating Scale, Lille Apathy Rating Scale, and Addenbrooke Cognitive Examination. HRQoL was assessed by PDQ-39 and EQ-5D. Multiple regression analysis was performed to estimate the PDQ-39 and EQ-5D index values based on various clinical factors. Results. Although females received significantly lower dosage of levodopa, they had significantly more disabling dyskinesia and worse postural instability. Anxiety, pain, sleep disturbances, and orthostatic symptoms were more frequent among females while sexual dysfunction, apathy, and daytime sleepiness were more severe among males. Women had worse HRQoL than men (EQ-5D index value: 0.620 ± 0.240 versus 0.663 ± 0.229, p = 0.025, and PDQ-39 SI: 27.1 ± 17.0 versus 23.5 ± 15.9, p = 0.010). Based on multiple regression analysis, sex was an independent predictor for HRQoL in PD. Conclusions. Based on our results, female sex is an independent predictor for having worse HRQoL in PD.

    Green mountain (GM), Norchip (NC) and Norland (NL) potato (Solanum tuberosum) cultivars were grown in the field under standard commercial practices to determine their relative susceptibility to oxidants and to evaluate the effectiveness of two antioxidants, EDU and benomyl, applied as soil drenches. The order of foliar susceptibility to oxidants was NL > NC > GM. Symptom severity directly correlated with cumulative oxidant dose, and the time of maximum plant sensitivity was cultivar-dependent. EDU significantly reduced foliar symptoms but benomyl did not. Untreated plants sustained up to a 31% reduction in tuber yield when compared to EDU treated plants. Reductions in specific gravity, tuber size and tuber number were year x cultivar dependent. The uptake and distribution of cadmium (Cd), another phytotoxic pollutant, in tobacco (Nicotiana tabacum L.) and tomato plants (Lycopersicon esculentum Mill.) grown in sand culture amended with 0 or 2.0 ..mu..g Cd/ml as CdCl/sub 2/ in a nutrient solution was compared. Tobacco accumulated twice as much Cd in the foliage as in the roots, whereas tomato plants contained only one-seventh as much Cd in the leaves. Although Cd-treated plants exhibited no visual toxicity symptoms, nor changes in percent dry weight, Mn and Fe concentrations were significantly reduced in the roots. Zinc concentrations of root and shoot tissue did not significantly change. When quaking aspen (Populus tremuloides) were grown in a sand substrate receiving nutrient solution amended with Cd (0-10 ..mu..g Cd/ml) and exposed to ozone (O/sub 3/) in a controlled and ambient environment, cadmium treated plants were more susceptible.

  6. Influence of oral mucosal lesions and oral symptoms on oral health related quality of life in dermatological patients: a cross sectional study in Sudan

    2012-01-01

    Background There are only few studies considering the impact of oral mucosal lesions (OML) on the oral quality of life of patients with different dermatological conditions. This study aimed to assess the relationship between oral health-related quality of life (OHRQoL) and OML and reported oral symptoms, perceived general and oral health condition and caries experience in adult skin diseased patients attending an outpatient dermatologic clinic in Sudan. Methods A cross-sectional survey was carried out with 544 diagnosed skin diseased patients (mean age 37.1 years, 50 % females), during the period October 2008 to January 2009. The patients were orally examined and OML and caries experience was recorded. The patients were interviewed using the Sudanese Arabic version of the OIDP. OHRQoL was evaluated by socio-demographic and clinical correlates according to number of types of OML diagnosed (no OML, one type of OML, > one type of OML) and number and types of oral symptoms. Results An oral impact (OIDP > 0) was reported by 190 patients (35.6 %) (mean OIDP total score 11.6, sd = 6.7). The prevalence of any oral impact was 30.5 %, 36.7 % and 44.1 %, in patients with no OML, one type of OML and more than one type of OML, respectively. Number of types of OML and number and types of oral symptoms were consistently associated with the OIDP scores. Patients who reported bad oral health, patients with ≥ 1 dental attendance, patients with > 1 type of OML, and patients with ≥ 1 type of oral symptoms were more likely than their counterparts in the opposite groups to report any OIDP. The odds ratios (OR) were respectively; 2.9 (95 % CI 1.9-4.5), 2.3 (95 % CI 1.5-3.5), 1.8 (95 % CI 1.1-3.2) and 6.7 (95 % CI 2.6-17.5). Vesiculobullous and ulcerative lesions of OML disease groups associated statistically significantly with OIDP. Conclusion OIDP was more frequently affected among skin diseased patients with than without OML. The frequency of

    We have demonstrated error-free operations of slow-light via stimulated Brillouin scattering (SBS) in optical fiber for 10-Gb/s signals with different modulation formats, including non-return-to-zero (NRZ), phase-shaped binary transmission (PSBT) and differential phase-shiftkeying (DPSK). The SBS gain bandwidth is broadened by using current noise modulation of the pump laser diode. The gain shape is simply controlled by the noise density function. Super-Gaussian noise modulation of the Brillouin pump allows a flat-top and sharp-edge SBS gain spectrum, which can reduce slow-light induced distortion in case of 10-Gb/s NRZ signal. The corresponding maximal delay-time with error-free operation is 35 ps. Then we propose the PSBT format to minimize distortions resulting from SBS filtering effect and dispersion accompanied with slow light because of its high spectral efficiency and strong dispersion tolerance. The sensitivity of the 10-Gb/s PSBT signal is 5.2 dB better than the NRZ case with a same 35-ps delay. The maximal delay of 51 ps with error-free operation has been achieved. Futhermore, the DPSK format is directly demodulated through a Gaussian-shaped SBS gain, which is achieved using Gaussian-noise modulation of the Brillouin pump. The maximal error-free time delay after demodulation of a 10-Gb/s DPSK signal is as high as 81.5 ps, which is the best demonstrated result for 10-Gb/s slow-light. PMID:19550988

    This study aimed to investigate the effects of Qigong intervention on quality of life (QOL), health-related functioning, and cancer-related symptoms in survivors of nasopharyngeal cancer (NPC). Twenty-five survivors of NPC were included in the experimental group (mean age ± SD: 55.4 ± 7.5 years) and 27 in the control group (mean age ± SD: 58.7 ± 9.5 years). The experimental group underwent a weekly 1.5-hour Qigong training program and an identical home program (three times/week) for six months. The control group received no training. Global health status/QOL, functioning, and cancer-related symptoms were assessed by the European Organization for Research and Treatment of Cancer QLQ-C30 and QLQ-H&N35 questionnaires before training began, after three months of Qigong training, at the end of the six-month Qigong intervention (i.e., posttest), and six months posttest. Intention-to-treat analysis revealed no statistically (P > 0.05) or clinically significant improvement in global health status/QOL, functioning, or symptoms in either group. The experimental group had 45.8% fewer sense-related (smell and taste) problems (P < 0.05) but 98.6% more speech-related problems (P < 0.05) than the control group after the Qigong intervention. Qigong training resulted in no apparent improvement in health-related QOL, functionality, or cancer-related symptoms in cancer-free survivors of NPC, except for a possible reduction in smell- and taste-related problems.

    In this study, we investigated the experience of children who died of cancer, as perceived by their parents. All the pediatric oncology departments in one German federal state were contacted and asked to invite parents who had lost a child to cancer in the period 2005-2006 to participate. Those parents who accepted were interviewed by means of a semi-structured questionnaire. In the participating 16 departments, 158 children died in 2005-2006. Parents of 48 children (38.3 percent) agreed to participate and were interviewed. Nearly all of the children had suffered from at least one distressing symptom. Pain and fatigue occurred most frequently. Symptoms were successfully treated over 65 percent of the time. In all, 64 percent of the children received home care services; 50 percent died at home, and only 10 percent in the ICU. Results suggest that some progress has been made in pediatric palliative care. To further improve end-of-life care for children with cancer, it is also necessary to evaluate parents' perspectives on structures for pediatric palliative care delivery. PMID:23413763

    ABSTRACT Response to mental health treatment varies highly among refugee patients. Research has not established which factors relate to differences in outcome. This study is a follow-up of Opaas and Hartmann's (2013) Rorschach Inkblot Method (RIM; Exner, 2003) pretreatment study of traumatized refugees, where 2 RIM principal components, Trauma Response and Reality Testing, were found descriptive of participants’ trauma-related personality functioning. This study's aims were to examine relationships of the RIM components with measures of anxiety, depression, posttraumatic stress, quality of life (QOL), employment, and exile language skills throughout 3 years. We found that impaired Reality Testing was related to more mental health symptoms and poorer QOL; furthermore, individuals with adequate Reality Testing improved in posttraumatic stress symptoms the first year and retained their improvement. Individuals with impaired Reality Testing deteriorated the first year and improved only slightly the next 2 years. The results of this study imply that traumatized refugee patients with impaired Reality Testing might need specific treatment approaches. Research follow-up periods should be long enough to detect changes. The reality testing impairment revealed by the RIM, mainly perceptual in quality, might not be easily detected by diagnostic interviews and self-report. PMID:26528822

    2011-01-01

    Background It remains unclear whether estrogenic botanical supplement (EBS) use influences breast cancer survivors' health-related outcomes. Methods We examined the associations of EBS use with health-related quality of life (HRQOL), with fatigue, and with 15 hormone-related symptoms such as hot flashes and night sweats among 767 breast cancer survivors participating in the Health, Eating, Activity, and Lifestyle (HEAL) Study. HRQOL was measured by the Medical Outcomes Study short form-36 physical and mental component scale summary score. Fatigue was measured by the Revised-Piper Fatigue Scale score. Results Neither overall EBS use nor the number of EBS types used was associated with HRQOL, fatigue, or hormone-related symptoms. However, comparisons of those using each specific type of EBS with non-EBS users revealed the following associations. Soy supplements users were more likely to have a better physical health summary score (odds ratio [OR] = 1.66, 95% confidence interval [CI] = 1.02-2.70). Flaxseed oil users were more likely to have a better mental health summary score (OR = 1.76, 95% CI = 1.05-2.94). Ginseng users were more likely to report severe fatigue and several hormone-related symptoms (all ORs ≥ 1.7 and all 95% CIs exclude 1). Red clover users were less likely to report weight gain, night sweats, and difficulty concentrating (all OR approximately 0.4 and all 95% CIs exclude 1). Alfalfa users were less likely to experience sleep interruption (OR = 0.28, 95% CI = 0.12-0.68). Dehydroepiandrosterone users were less likely to have hot flashes (OR = 0.33, 95% CI = 0.14-0.82). Conclusions Our findings indicate that several specific types of EBS might have important influences on a woman's various aspects of quality of life, but further verification is necessary.

    This study aims to evaluate the effects of voice rehabilitation with indwelling voice prosthesis on quality of life, depression, anxiety, self-esteem, and sexual functions in laryngectomy patients. Provox-1 was applied to 30 patients who underwent total laryngectomy by opening a tracheoesophageal fistula. WHO Quality of Life-BREF, Beck Depression Inventory, Beck Anxiety Inventory, Rosenberg Self-Esteem Scale, Arizona Sexual Experience Scale forms were asked to be filled out by the patients before voice prosthesis application. These tests were asked to be filled out again 3 months later after the voice prosthesis application. Paired samples and Wilcoxon tests were used to compare before and after operation values. Indwelling voice prosthesis was found to improve quality of life, self-esteem, and sexual function (p < 0.05). Additionally, symptoms of depression and anxiety were regressed (p < 0.05). Indwelling voice prosthesis was found to especially increase the quality of life and decrease depression (p < 0.05).

  14. Indoor air quality and health

    NASA Astrophysics Data System (ADS)

    Jones, A. P.

    During the last two decades there has been increasing concern within the scientific community over the effects of indoor air quality on health. Changes in building design devised to improve energy efficiency have meant that modern homes and offices are frequently more airtight than older structures. Furthermore, advances in construction technology have caused a much greater use of synthetic building materials. Whilst these improvements have led to more comfortable buildings with lower running costs, they also provide indoor environments in which contaminants are readily produced and may build up to much higher concentrations than are found outside. This article reviews our current understanding of the relationship between indoor air pollution and health. Indoor pollutants can emanate from a range of sources. The health impacts from indoor exposure to combustion products from heating, cooking, and the smoking of tobacco are examined. Also discussed are the symptoms associated with pollutants emitted from building materials. Of particular importance might be substances known as volatile organic compounds (VOCs), which arise from sources including paints, varnishes, solvents, and preservatives. Furthermore, if the structure of a building begins to deteriorate, exposure to asbestos may be an important risk factor for the chronic respiratory disease mesothelioma. The health effects of inhaled biological particles can be significant, as a large variety of biological materials are present in indoor environments. Their role in inducing illness through immune mechanisms, infectious processes, and direct toxicity is considered. Outdoor sources can be the main contributors to indoor concentrations of some contaminants. Of particular significance is Radon, the radioactive gas that arises from outside, yet only presents a serious health risk when found inside buildings. Radon and its decay products are now recognised as important indoor pollutants, and their effects are

    Abstract Background The World Health Organization recognizes depression as one of the most burdensome diseases in the world. Among cancer patients, depression is significantly associated with shorter survival, independent of the influence of biomedical prognostic factors. Although cancer is the third leading cause of morbidity and mortality among Filipinos, little is known about depressive symptoms and their influence on health-related quality of life in this population. We assessed the prevalence of, and factors associated with, depressive symptoms and their influence on health-related quality of life in Filipino patients with cancer. Methods The Patient Health Questionnaire (PHQ)-8 and the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 were administered to all inpatients and outpatients, age >=18 years presenting for cancer treatment. Results Twenty-two percent (n=53/247) were categorized as depressed, using a PHQ-8 cutoff of ≥10. Depressed patients scored lower on cognitive, emotional, role, physical, and social functioning than those who scored PHQ<10 (all P<0.001). Depression varied by disease status, performance status and marital status (all P<0.001). However, only performance status (OR [odds ratio]=2.20; 95% CI=1.60, 3.00) and disease status (OR=2.4; 95% CI=1.13, 5.22) were significantly associated with depression in the multivariable model. Conclusions Depression is prevalent in Filipino cancer patients. The findings provide empirical support for the development of mental health services in this understudied population. This study, the first to assess the prevalence of and factors associated with depression in Filipino cancer patients, needs further validation. PMID:24047452

    Introduction Chronic obstructive pulmonary disease (COPD) is a progressive disease with symptoms that can have a major impact on patients’ physical health. The aim of this study was to evaluate quality of life (QoL), symptom severity and dyspnoea in COPD patients treated with aclidinium up to 24 weeks. Methods In this prospective non-interventional multicentre study (198 centres in Sweden, Denmark, and Norway), COPD patients (age ≥40 years) who started treatment with aclidinium (initial therapy, change of treatment, or add-on therapy) could be included. Health-related QoL was obtained by COPD assessment test (CAT). Symptoms were evaluated on a 6-point Likert scale. The modified Medical Research Council (mMRC) Dyspnoea Scale was used as a simple grading system to assess the level of dyspnoea/shortness of breath from0 to 4. Patients on treatment with aclidinium who completed baseline and at least one follow-up visit (week 12 or 24) were included in the study population. Results Overall, 1,093 patients were enrolled (mean 69 years, 54% females), one-third had ≥1 exacerbation the year prior to baseline. At enrolment, 48% were LAMA naïve. Mean (standard deviation, SD) CAT score decreased from 16.9 (7.7) at baseline to 14.3 (7.3) at week 24 (p<0.01) with a decrease in all individual CAT items (p<0.05). Mean difference in morning and night-time symptoms from baseline to week 24 was −0.60 (SD 2.51) and −0.44 (SD 2.48), respectively (both p<0.001). Mean (SD) mMRC Dyspnoea Scale changed from 1.6 (1.0) at baseline to 1.5 (1.0) at week 24 (p<0.001). Conclusion In this observational study of a Nordic real-life COPD population, treatment with aclidinium was associated with a clinically important improvement in QoL and morning and night-time symptoms, most pronounced in the LAMA naïve group. However, there is still room for improvement in the management of symptomatic COPD patients. PMID:27387608

    Internet-based interventions are increasingly recognized as effective for the treatment and prevention of depression; however, there is a paucity of research investigating potential secondary benefits. From a consumer perspective, improvements in indicators of wellbeing such as perceived quality of life may represent the most important outcomes for evaluating the effectiveness of an intervention. This study investigated the 'secondary' benefits for self-esteem, empowerment, quality of life and perceived social support of two 12-week online depression interventions when delivered alone and in combination. Participants comprised 298 adults displaying elevated psychological distress. Participants were randomised to receive: an Internet Support Group (ISG); an automated Internet psycho-educational training program for depression; a combination of these conditions; or a control website. Analyses were performed on an intent-to-treat basis. Following the automated training program immediate improvements were shown in participants׳ self-esteem and empowerment relative to control participants. Improvements in perceived quality of life were reported 6-months following the completion of the intervention when combined with an ISG. These findings provide initial evidence for the effectiveness of this online intervention for improving individual wellbeing beyond the primary aim of the treatment. However, further research is required to investigate the mechanisms underlying improvement in these secondary outcomes. PMID:24534125

    Background. HCV infection is associated with musculoskeletal manifestations such as chronic widespread pain, sicca syndrome, polyarthritis, and a reduced HRQOL. Little data is available on the effect of treatment on these manifestations. This study measured changes in extrahepatic symptoms and HRQOL before and after antiviral treatment in a large UK patient cohort. Methods. 118 patients completed HQLQ and rheumatological questionnaires before and after treatment with pegylated interferon-α and ribavirin, with specific regard to chronic widespread pain, sicca syndrome, and sustained virological response. Results. There was significant improvement in HQLQ domains of physical functioning, physical disability, social functioning, limitations and health distress due to hepatitis, and general health. There was significant deterioration in domains of positive well-being, health distress, and mental health. There was a significant decline prevalence of CWP (26.3% versus 15.3%, P = 0.015). Sicca syndrome prevalence fell insignificantly (12.7% versus 11%). SVR was associated positively with all HRQOL changes and significantly with CWP remission. Conclusions. HCV antivirals significantly improve poor HRQOL scores and CWP. Before treatment, both were common, coassociated, and unaccounted for through mixed cryoglobulinemia alone. Although a role of the hepatitis C virus in CWP cannot be deduced by these results, symptomatic improvement via antiviral treatment exists for this subset of patients. PMID:24223303

    Few studies comprehensively assessed psychological and behavioral functioning in adolescent kidney transplant patients. The purpose of this cross-sectional study was to evaluate depression, QOL, treatment adherence and presence of side effects from the perspective of the patient and his parents, and to compare scores with norm data. All patients (age 10-18 yr) and their parents completed the following instruments: KIDSCREEN-27 (QOL), a treatment adherence interview, the MTSOSD-59R (side effects) and the Beck Depression Inventory (depression). Twenty-three of 26 patients and 22 parents agreed to participate (70% male; median age 15 yr). Adolescents rated their QOL as satisfactory, but parents reported significant problems on several QOL dimensions. Depressive symptoms occurred in 17.4%, and 75% were non-adherent with their immunosuppressive drugs (confirmed by their parents) and show other problematic health behavior, including smoking, illicit drug use, dietary non-adherence, and suboptimal exercise levels. The most frequently occurring side effects were increased appetite, fatigue and headache; the most distressing ones were hair loss or thinning of hair, warts on hands or feet, and sores in the mouth or on the lips. Our results underscore the need for regular screening and adequate treatment of the above-mentioned aspects. PMID:19497017

    Purpose: To evaluate the clinical outcome for uterine adenomyosis with or without uterine leiomyomata 40 months after uterine artery embolization (UAE). Methods: Forty women aged 39-56 years (median 46 years) with symptomatic uterine adenomyosis and magnetic resonance imaging findings of uterine adenomyosis with or without combined uterine leiomyomata underwent UAE. Self-perceived changes in clinical symptoms were assessed, and residual symptom severity and health-related quality of life (HRQOL) after UAE were evaluated. Clinical failure was defined as no symptomatic improvement or second invasive therapy after UAE. Results were stratified by the extent of uterine adenomyosis at baseline magnetic resonance imaging. Results: Patients were followed for a median of 40 months (range 5-102 months). UAE led to symptomatic control after UAE in 29 (72.5%) of 40 patients while 11 women underwent hysterectomy (n = 10) or dilatation and curettage (n = 1) for therapy failure. No significant difference between women with pure uterine adenoymosis and women with uterine adenomyosis combined with uterine leiomyomata was observed. Best results were shown for UAE in uterine adenomyosis with uterine leiomyomata predominance as opposed to predominant uterine adenomyosis with minor fibroid disease (clinical failure 0% vs. 31.5%, P = 0.058). Throughout the study group, HRQOL score values increased and symptom severity scores decreased after UAE. Least improvement was noted for women with pure adenomyosis. Conclusions: UAE is clinically effective in the long term in most women with uterine adenomyosis. Symptomatic control and HRQOL were highest in patients with combined disease of uterine adenomyosis but leiomyomata predominance.

    BACKGROUND: In addition to symptoms, such as dyspnea and fatigue, patients with chronic obstructive pulmonary disease (COPD) also experience mood disturbances. OBJECTIVE: To explore the relationships between health-related quality of life measures collected from patients with stable COPD and a commonly used measure of depression and anxiety. METHODS: The present analysis was a retrospective study of patients with COPD enrolled in a pulmonary rehabilitation program. Hospital Anxiety and Depression Scale (HADS), Chronic Respiratory Disease Questionnaire (CRQ), Medical Research Council dyspnea scale and 6 min walk test data were collected. Statistical analyses were performed using Spearman’s correlations, and categorical regression and categorical principal component analysis were interpreted using the biplot methodology. RESULTS: HADS anxiety scores retrieved from 80 patients were grouped as ‘no anxiety’ (n=43 [54%]), ‘probable anxiety’ (n=21 [26%]) and ‘presence of anxiety’ (n=16 [20%]). HADS depression scores were similarly grouped. There was a moderate relationship between the anxiety subscale of the HADS and both the emotional function (r=−0.519; P<0.01) and mastery (r=−0.553; P<0.01) domains of the CRQ. Categorical regression showed that the CRQ-mastery domain explained 40% of the total variation in anxiety. A principal component analysis biplot showed that the highest distance between the groups was along the mastery domain, which separated patients without feelings of anxiety from those with anxiety. However, none of the CRQ domains were able to discriminate the three depression groups. CONCLUSIONS: The CRQ-mastery domain may identify symptoms of anxiety in patients with COPD; however, the relationship is not strong enough to use the CRQ-mastery domain as a surrogate measure. None of the CRQ domains were able to discriminate the three depression groups (no depression, probable and presence); therefore, specific, validated tools to identify

    Objectives. To evaluate the effectiveness of Baduanjin Qigong exercise on sleep, fatigue, anxiety, and depressive symptoms in chronic fatigue syndrome- (CFS-) like illness and to determine the dose-response relationship. Methods. One hundred fifty participants with CFS-like illness (mean age = 39.0, SD = 7.9) were randomly assigned to Qigong and waitlist. Sixteen 1.5-hour Qigong lessons were arranged over 9 consecutive weeks. Pittsburgh Sleep Quality Index (PSQI), Chalder Fatigue Scale (ChFS), and Hospital Anxiety and Depression Scale (HADS) were assessed at baseline, immediate posttreatment, and 3-month posttreatment. The amount of Qigong self-practice was assessed by self-report. Results. Repeated measures analyses of covariance showed a marginally nonsignificant (P = 0.064) group by time interaction in the PSQI total score, but it was significant for the “subjective sleep quality” and “sleep latency” items, favoring Qigong exercise. Improvement in “subjective sleep quality” was maintained at 3-month posttreatment. Significant group by time interaction was also detected for the ChFS and HADS anxiety and depression scores. The number of Qigong lessons attended and the amount of Qigong self-practice were significantly associated with sleep, fatigue, anxiety, and depressive symptom improvement. Conclusion. Baduanjin Qigong was an efficacious and acceptable treatment for sleep disturbance in CFS-like illness. This trial is registered with Hong Kong Clinical Trial Register: HKCTR-1380. PMID:25610473

    The present study examined the effects of illness representation, perceived quality of information provided by the health-care professional, and perceived social support on the depressive symptoms of the caregivers of children with leukemia. The sample was composed of 71 caregivers of children with leukemia living in Turkey. The obtained data were analyzed by path analysis. The results show that caregivers of children with leukemia experience higher levels of depressive symptoms when they have negative illness representation and lower levels of depressive symptoms when they perceive higher levels of social support. Moreover, they perceive higher social support when they perceive high quality of information provided by health-care professionals. It can be suggested that intervention programs which aim to increase caregivers' social support and change their illness representation in a positive way would be helpful for the caregivers showing depressive symptoms.

    Objective To examine associations of symptoms with physical and mental health-related quality of life (HRQOL) in colorectal cancer (CRC) and lung cancer patients Methods Newly diagnosed CRC (n=3,040) and lung cancer (n=2,297) participants of the Cancer Care Outcomes Research and Surveillance Consortium completing surveys on general HRQOL and symptoms. HRQOL was measured by the SF-12 physical and mental component summary scores (PCS and MCS, respectively). Non-specific cancer symptoms were measured using EORTC-QLQ-C30 items. Cancer type-specific modules developed by the EORTC were used to assess CRC and lung cancer-specific symptoms. For each cancer, linear regression models examined the relationship of non-specific and cancer-specific symptoms with PCS and MCS, controlling for demographic and clinical information. Results CRC and lung cancer patients’ PCS scores were below the general population norm of 50 (43 and 37, respectively) and MCS scores were at population norm. For CRC, in the model with both symptom indices, an increase in non-specific symptoms was more strongly associated with lower PCS and MCS scores than an increase in CRC-specific symptoms (standardized coefficients; β=−0.41 vs. −0.09 for PCS and β=−0.38 vs. −0.08 for MCS). In the similar model for lung cancer, increases in lung cancer-specific symptoms were more strongly associated with lower PCS scores (β=−0.34 vs. −0.20) while non-specific symptoms were more strongly associated with lower MCS (β=−0.34 vs. −0.14). Conclusion Symptoms were associated with HRQOL impairments in recently diagnosed patients. Additional supportive care implemented early in cancer care, regardless of cancer stage, may provide symptom relief and improve HRQOL. PMID:25891437

    Background Over the last two decades, the number of studies on electronic symptom reporting has increased greatly. However, the field is very heterogeneous: the choices of patient groups, health service innovations, and research targets seem to involve a broad range of foci. To move the field forward, it is necessary to build on work that has been done and direct further research to the areas holding most promise. Therefore, we conducted a comprehensive review of randomized controlled trials (RCTs) focusing on electronic communication between patient and provider to improve health care service quality, presented in two parts. Part 2 investigates the methodological quality and effects of the RCTs, and demonstrates some promising benefits of electronic symptom reporting. Objective To give a comprehensive overview of the most mature part of this emerging field regarding (1) patient groups, (2) health service innovations, and (3) research targets relevant to electronic symptom reporting. Methods We searched Medline, EMBASE, PsycINFO, Cochrane Central Register of Controlled Trials, and IEEE Xplore for original studies presented in English-language articles published from 1990 to November 2011. Inclusion criteria were RCTs of interventions where patients or parents reported health information electronically to the health care system for health care purposes and were given feedback. Results Of 642 records identified, we included 32 articles representing 29 studies. The included articles were published from 2002, with 24 published during the last 5 years. The following five patient groups were represented: respiratory and lung diseases (12 studies), cancer (6), psychiatry (6), cardiovascular (3), and diabetes (1). In addition to these, 1 study had a mix of three groups. All included studies, except 1, focused on long-term conditions. We identified four categories of health service innovations: consultation support (7 studies), monitoring with clinician support (12), self

    Disaster work has shown to cause PTSD symptoms and subjective health complaints in professional emergency personnel. However, very little is known about how disaster work affects community volunteers. This first time longitudinal study examined factors contributing to post-traumatic stress disorder symptoms (PTSD) and subjective health complaints in volunteers working in an earthquake setting. At six and eighteen months post disaster, a sample of 506 Indonesian Red Cross volunteers were assessed using the Impact of Event Scale-Revised and the Subjective Health Complaints Inventory. Factors analyzed in relation to the outcomes included: peri-traumatic distress, level of personal affectedness by the disaster, sleep quality and loss of resources as a consequence of the disaster. At 18 months post-disaster the findings showed high levels of PTSD symptoms and subjective health complaints. Quality of sleep was related to both outcomes but resource loss only to PTSD symptoms. Neither peri-traumatic distress nor level of affectedness by the disaster (external versus directly affected volunteers), were predictive of symptoms. This study indicates that characteristics of disaster work e.g. low quality of sleep, may be an important contributor to PTSD symptoms and subjective health complaints in volunteers. PMID:25445088

    Background: A key component to monitoring and investigating patient QOL is through patient reported health related quality of life (HRQOL) outcome measures. Many instruments have been used to assess HRQOL in bladder cancer and each instrument varies in its development, validation, the context of its usage in the literature and its applicability to certain disease states. Objective: In this review, we sought to summarize how clinicians and researchers should most appropriately utilize the available HRQOL instruments for bladder cancer. Methods: We performed a comprehensive literature search of each instrument used in bladder cancer, paying particular attention to the outcomes assessed. We used these outcomes to group the available instruments into categories best reflecting their optimal usage by stage of disease. Results: We found 5 instruments specific to bladder cancer, of which 3 are validated. Only one of the instruments (the EORTC-QLQ-NMIBC24) was involved in a randomized, prospective validation study. The most heavily used instruments are the EORTC-QLQ-BLM30 for muscle-invasive disease and the FACT-Bl which is used across all disease states. Of the 5 available instruments, 4 are automatically administered with general instruments, while the BCI lacks modularity, and requires co-administration with a generalized instrument. Conclusion: There are multiple strong instruments for use in gauging HRQOL in bladder cancer patients. We have divided these instruments into three categories which optimize their usage: instruments for use following NMIBC treatments (EORTC-QLQ-NMIBC24), instruments for use following radical cystectomy (FACT-Bl-Cys and EORTC-QLQ-BLM30) and more inclusive instruments not limited by treatment modality (BCI and FACT-Bl).

    BACKGROUND In a phase 3, randomized, open-label trial (COMPARZ; NCT00720941), pazopanib was found to be non-inferior to sunitinib in terms of progression-free survival in patients with metastatic renal cell carcinoma with no prior therapy. Overall treatment differences were evaluated in a post hoc analysis using a quality-adjusted time without symptoms of disease or toxicity of treatment (Q-TWiST) methodology. METHODS Each patient’s overall survival was partitioned into 3 mutually exclusive health states: grade 3 or 4 toxicity (TOX), time without symptoms of disease or grade 3/4 toxicity (TWiST), and time after progression or relapse (REL). Time spent in each state was weighted by a health-state utility associated with that state and summed to calculate the Q-TWiST. A threshold utility analysis was used, applying utilities across the range of 0 (similar to death) to 1 (perfect health). RESULTS A total of 1,110 patients were enrolled (557 pazopanib, 553 sunitinib). The mean time spent with TOX was 31 days (95% confidence interval, 13–49) higher for sunitinib compared with pazopanib. In the threshold utility analysis, the difference in Q-TWiST ranged from -11 days (utility TOX=1, REL=0) to 43 days (TOX=0, REL=1), in favor of pazopanib across most utility combinations. Differences were significant in less than half of the utility combinations examined, typically when the utility for TOX was lower than the utility for REL. CONCLUSIONS Patients randomized to pazopanib had slightly longer Q-TWiST compared with sunitinib patients, primarily due to a reduced length of time spent with grade 3/4 toxicities. PMID:27000445

    2013-01-01

    Background Women with polycystic ovary syndrome (PCOS) have symptoms of depression and anxiety and impaired health related quality of life (HRQoL). Here we test the post-hoc hypothesis that acupuncture and exercise improve depression and anxiety symptoms and HRQoL in PCOS women. Methods Seventy-two PCOS women were randomly assigned to 16 weeks of 1) acupuncture (n = 28); 2) exercise (n = 29); or 3) no intervention (control) (n = 15). Outcome measures included: change in Montgomery Åsberg Depression Rating Scale (MADRS-S), Brief Scale for Anxiety (BSA-S), Swedish Short-Form 36 (SF-36), and PCOS Questionnaire (PCOSQ) scores from baseline to after 16-week intervention, and to 16-week post-intervention follow-up. Results A reduction in MADRS-S and BSA-S from baseline to 16-weeks post-intervention follow-up was observed for the acupuncture group. The SF-36 domains role physical, energy/vitality, general health perception and the mental component of summary scores improved in the acupuncture group after intervention and at follow-up. Within the exercise group the role physical decreased after treatment, while physical functioning and general health perception scores increased at follow-up. The emotion domain in the PCOSQ improved after 16-weeks of intervention within all three groups, and at follow-up in acupuncture and exercise groups. At follow-up, improvement in the infertility domain was observed within the exercise group. Conclusion There was a modest improvement in depression and anxiety scores in women treated with acupuncture, and improved HRQoL scores were noted in both intervention groups. While not a primary focus of the trial, these data suggest continued investigation of mental health outcomes in women treated for PCOS.

    Objective To estimate the magnitude in which Parkinson’s disease (PD) symptoms and health- related quality of life (HRQoL) determined PD costs over a 4-year period. Materials and Methods Data collected during 3-month, each year, for 4 years, from the ELEP study, included sociodemographic, clinical and use of resources information. Costs were calculated yearly, as mean 3-month costs/patient and updated to Spanish €, 2012. Mixed linear models were performed to analyze total, direct and indirect costs based on symptoms and HRQoL. Results One-hundred and seventy four patients were included. Mean (SD) age: 63 (11) years, mean (SD) disease duration: 8 (6) years. Ninety-three percent were HY I, II or III (mild or moderate disease). Forty-nine percent remained in the same stage during the study period. Clinical evaluation and HRQoL scales showed relatively slight changes over time, demonstrating a stable group overall. Mean (SD) PD total costs augmented 92.5%, from €2,082.17 (€2,889.86) in year 1 to €4,008.6 (€7,757.35) in year 4. Total, direct and indirect cost incremented 45.96%, 35.63%, and 69.69% for mild disease, respectively, whereas increased 166.52% for total, 55.68% for direct and 347.85% for indirect cost in patients with moderate PD. For severe patients, cost remained almost the same throughout the study. For each additional point in the SCOPA-Motor scale total costs increased €75.72 (p = 0.0174); for each additional point on SCOPA-Motor and the SCOPA-COG, direct costs incremented €49.21 (p = 0.0094) and €44.81 (p = 0.0404), respectively; and for each extra point on the pain scale, indirect costs increased €16.31 (p = 0.0228). Conclusions PD is an expensive disease in Spain. Disease progression and severity as well as motor and cognitive dysfunctions are major drivers of costs increments. Therapeutic measures aimed at controlling progression and symptoms could help contain disease expenses. PMID:26698860

    We derive the size and temperature profile of the accretion disk of the lensed quasar SBS 0909+532 by measuring the wavelength dependence (chromaticity) of the microlensing magnification produced by the stars in the lens galaxy. After correcting for extinction using the flux ratios of 14 emission lines, we observe a marked change in the B-A flux ratio with wavelength, varying from -0.67 ± 0.05 mag at (rest frame) ~1460 Å to -0.24 ± 0.07 mag at ~6560 Å. For λ >~ 7000 Å both effects, extinction and microlensing, look minimal. Simulations indicate that image B rather than A is strongly microlensed. If we model the change in disk size from 1460 Å to 6560 Å using a Gaussian source (I vprop exp(-R 2/2r 2 s )) with a disk size scaling with wavelength as rs vprop λ p , we find rs = 7+5 -3 light-days at 1460 Å and p = 0.9+0.6 -0.3 for uniform priors on rs and p, and rs = 4+3 -3 light-days and p = 1.0+0.6 -0.4 for a logarithmic prior on rs . The disk temperature profile T vprop R -1/p is consistent with thin disk theory (T vprop R -3/4), given the uncertainties. The estimates of rs are also in agreement with the size inferred from thin disk theory using the estimated black hole mass (M BH ~= 2 × 109 M sun) but not with the smaller size estimated from thin disk theory and the optical flux. We also use the flux ratios of the unmicrolensed emission lines to determine the extinction curve of the dust in the lens galaxy, finding that it is similar to that of the LMC2 Supershell.

    This paper studied associations between ocular symptoms, rhinitis, throat and dermal symptoms, headache and fatigue in students by ethnicity and in relation to exposure to chemical microbial markers and fungal DNA in vacuumed dust in schools in Malaysia. A total of 462 students from 8 randomly selected secondary schools in Johor Bahru, Malaysia, participated (96% response rate). Dust was vacuumed from 32 classrooms and analysed for levels of five types of endotoxin as 3-hydroxy fatty acids (C10, C12, C14, C16 and C18 3-OH), muramic acid, ergosterol and five sequences of fungal DNA. Multiple logistic regression was applied. Totally 11.9% reported weekly ocular symptoms, 18.8% rhinitis, 15.6% throat and 11.1% dermal symptoms, 20.6% headache and 22.1% tiredness. Totally 21.1% reported pollen or furry pet allergy (atopy) and 22.0% parental asthma or allergy. Chinese students had less headache than Malay and Indian had less rhinitis and less tiredness than Malay. Parental asthma/allergy was a risk factor for ocular (odds ratio=3.79) and rhinitis symptoms (OR=3.48). Atopy was a risk factor for throat symptoms (OR=2.66), headache (OR=2.13) and tiredness (OR=2.02). There were positive associations between amount of fine dust in the dust samples and ocular symptoms (p<0.001) and rhinitis (p=0.006). There were positive associations between C14 3-OH and rhinitis (p<0.001) and between C18 3-OH and dermal symptoms (p=0.007). There were negative (protective) associations between levels of total endotoxin (LPS) (p=0.004) and levels of ergosterol (p=0.03) and rhinitis and between C12 3-OH and throat symptoms (p=0.004). In conclusion, the amount of fine dust in the classroom was associated with rhinitis and other SBS symptoms and improved cleaning of the schools is important. Endotoxin in the school dust seems to be mainly protective for rhinitis and throat symptoms but different types of endotoxin could have different effects. The ethnic differences in symptoms among the students

  19. HIV-related stigma and physical symptoms have a persistent influence on health-related quality of life in Australians with HIV infection

    2013-01-01

    Background The health-related quality of life (HRQL) of people living with HIV infection is an important consideration in HIV management. The PROQOL-HIV psychometric instrument was recently developed internationally as a contemporary, discriminating HIV-HRQL measure incorporating influential emotional dimensions such as stigma. Here we present the first within-country results of PROQOL-HIV using qualitative and quantitative data collected from a West Australian cohort who participated in the development and validation of PROQOL-HIV, and provide a comprehensive picture of HRQL in our setting. Methods We carried out a secondary analysis of data from Australian patients who participated in the international study: 15 in-depth interviews were conducted and 102 HRQL surveys using the PROQOL-HIV instrument and a symptom questionnaire were administered. We employed qualitative methods to extract description from the interview data and linear regression for exploration of the composite and sub-scale scores derived from the survey. Results Interviews revealed the long-standing difficulties of living with HIV, particularly in the domains of intimate relationships, perceived stigma, and chronic ill health. The novel PROQOL-HIV instrument discriminated impact of treatment via symptomatology, pill burden and treatment duration. Patients demonstrated lower HRQL if they were: newly diagnosed (p=0.001); naive to anti-retroviral treatment (p=0.009); reporting depression, unemployment or a high frequency of adverse symptoms, (all p<0.001). Total HRQL was notably reduced by perceived stigma with a third of surveyed patients reporting persistent fears of both disclosing their HIV status and infecting others. Conclusions The analysis showed that psychological distress was a major influence on HRQL in our cohort. This was compounded in people with poor physical health which in turn was associated with unemployment and depression. People with HIV infection are living longer and residual

    Objective The purpose of this study was to examine the prevalence of posttraumatic stress symptoms (PTSS) in patients with renal cell carcinoma (RCC), the relationships and co-occurrence between PTSS, depressive, and other cancer-related symptoms, and the ability of a single-item distress question to identify patients with PTSS. Methods Patients with Stage I-IV RCC completed assessments of depressive symptoms (CES-D), PTSS (IES), cancer-related symptoms (MDASI), fatigue (BFI), and sleep disturbance (PSQI). We used the distress item on the MDASI as a distress screener and general linear model analyses to test study hypotheses. Results Of 287 patients (29% stage IV; 42% female; mean age=58 years), 46% (n=131) reported psychiatric symptoms with 15% (n=44) reporting comorbid clinical levels of depressive symptoms and PTSS; 24% (n=70) PTSS alone; and 6% (n=17) depressive symptoms alone. Controlling for age, gender, and stage, patients with comorbid depressive symptoms and PTSS reported more cancer-related symptoms (P<.0001), fatigue (P<.0001), and sleep disturbance (P=.0003) than those with PTSS alone and more cancer-related symptoms (P=.002) and fatigue (P=.09) than those with depressive symptoms alone. Sensitivity analyses revealed that 26.9% of negative cases on the distress item fell within the clinical range of the IES and 9.3% of negative cases met caseness on the CES-D. Conclusions PTSS occurred both independently as well as comorbid with depressive symptoms in patients with RCC. PTSS were correlated with overall cancer symptom burden. Single-item distress screening was less sensitive in detecting PTSS than depressive symptoms. Therefore, additional screening strategies are required in the clinical setting. PMID:25690556

    Colorectal cancer (CRC) is common worldwide. The high prevalence of the disease raises concerns about how CRC influences the health-related quality of life (QoL). To explore the impact of physiological symptoms and complications of CRC on patients' QoL, we conducted a cross-sectional survey using the FACT-C self-report instrument. The chi-square test was used to compare qualitative data. We found that pain was reported by most of the patients (n = 31; 77.5 %). Furthermore, male patients were more likely to complain of pain "mostly" as compared with females (P = .032). We found no significant differences between genders regarding general health-related questions. A greater proportion of male patients often complained of abdominal cramps (P = .542), weight loss (P = .086), and diarrhea (P = .408). More than half of the patients (n = 26; 65 %) reported having a good appetite; a greater proportion of males reported having a good appetite "mostly" (P = .014). Social and psychological qualities of life were not significantly different between male and female patients. Male and female patients did not differ in their report of disease acceptance (P = .420) and ability to enjoy life (P = .744). No difference was also found between genders regarding contentment with QoL (P = .793) or ability to sleep well (P = .695). Furthermore, there were no differences between genders regarding job fulfillment (P = .272). Our results add to the growing body of knowledge about the effect of CRC on QoL. Importantly, the differences in self-reported pain and appetite between male and female patients in our study suggest the importance of gender-based treatments in improving patients' QoL.

    2013-01-01

    Background Solid-organ transplantations (SOT) are usually life-saving high-tech medical procedures. The transplantation itself and the intensive care unit stay could be traumatic stressors triggering posttraumatic stress symptoms (PTSS). Our retrospective follow-up study aimed to explore preoperative risk factors of PTSS in a cohort of SOT recipients, and we investigated how PTSS are associated with health-related quality of life (HRQOL) and life satisfaction. Methods 126 SOT recipients were enrolled in this investigation. Psychiatric examination of all SOT candidates based on the Transplant Evaluation Rating Scale was carried out before SOT, and after SOT, recipients completed the PTSS-10, the SF-36 and the FLZ. Results After the surgical intervention 19 (15.1%) SOT recipients had clinical significant PTSS. Preoperative risk factors for developing postoperative PTSS were: 1.) preexisting psychiatric morbidity, 2.) history of retransplantation, 3.) chronic benzodiazepine consumption, 4.) age, and 5.) type of transplantation. SOT-related PTSS were associated with maximal decrements in HRQOL and life satisfaction. The following HRQOL and life satisfaction domains were affected: Physical Functioning, Role Physical, Pain, General Health, Vitality, Social Functioning, Role Emotional, Mental Health, Occupation/Work and Character/Own Skills. Conclusion SOT recipients may face a major risk of transplantation- and treatment-related PTSS and the development of impairments to HRQOL and life satisfaction. PMID:23822659

    There is no consensus as to what symptoms or quality-of-life (QOL) domains should be measured as patient-reported outcomes (PROs) in ovarian cancer clinical trials. A panel of experts convened by the National Cancer Institute reviewed studies published between January 2000 and August 2011. The results were included in and combined with an expert consensus-building process to identify the most salient PROs for ovarian cancer clinical trials. We identified a set of PROs specific to ovarian cancer: abdominal pain, bloating, cramping, fear of recurrence/disease progression, indigestion, sexual dysfunction, vomiting, weight gain, and weight loss. Additional PROs identified in parallel with a group charged with identifying the most important PROs across cancer types were anorexia, cognitive problems, constipation, diarrhea, dyspnea, fatigue, nausea, neuropathy, pain, and insomnia. Physical and emotional domains were considered to be the most salient domains of QOL. Findings of the review and consensus process provide good support for use of these ovarian cancer-specific PROs in ovarian cancer clinical trials. PMID:25006190

    We report the synthesis of several unique, boron-rich pincer complexes derived from m-carborane. The SeBSe and SBS pincer ligands can be synthesized via two independent synthetic routes, and are metallated with Pd(II). These structures represent unique coordinating motifs, each with a Pd-B(2) bond chelated by two thio- or selenoether ligands. This class of structures serves as the first example of boron-metal pincer complexes, and possesses several interesting electronic properties imposed by the m-carborane cage. PMID:19583431

  6. Causes of Indoor Air Quality Problems in Schools: Summary of Scientific Research

    In the modern urban setting, most individuals spend about 80% of their time indoors and are therefore exposed to the indoor environment to a much greater extent than to the outdoors (Lebowitz 1992). Concomitant with this increased habitation in urban buildings, there have been numerous reports of adverse health effects related to indoor air quality (IAQ) (sick buildings). Most of these buildings were built in the last two decades and were constructed to be energy-efficient. The quality of air in the indoor environment can be altered by a number of factors: release of volatile compounds from furnishings, floor and wall coverings, and other finishing materials or machinery; inadequate ventilation; poor temperature and humidity control; re-entrainment of outdoor volatile organic compounds (VOCs); and the contamination of the indoor environment by microbes (particularly fungi). Armstrong Laboratory (1992) found that the three most frequent causes of IAQ are (1) inadequate design and/or maintenance of the heating, ventilation, and air-conditioning (HVAC) system, (2) a shortage of fresh air, and (3) lack of humidity control. A similar study by the National Institute for Occupational Safety and Health (NIOSH 1989) recognized inadequate ventilation as the most frequent source of IAQ problems in the work environment (52% of the time). Poor IAQ due to microbial contamination can be the result of the complex interactions of physical, chemical, and biological factors. Harmful fungal populations, once established in the HVAC system or occupied space of a modern building, may episodically produce or intensify what is known as sick building syndrome (SBS) (Cummings and Withers 1998). Indeed, SBS caused by fungi may be more enduring and recalcitrant to treatment than SBS from multiple chemical exposures (Andrae 1988). An understanding of the microbial ecology of the indoor environment is crucial to ultimately resolving many IAQ problems. The incidence of SBS related to multiple

    Both painful and nonpainful somatic symptoms essentially characterize clinical states of depressive mood. So far, this well-established psychopathological knowledge has been appreciated only insufficiently by the official diagnostic sys-terms of the Diagnostic and Statistical Manual of Mental Disorders, 4th edition, Text Revision (DSM-IVTR) and the ICD-10 Classification of Mental and Behavioral Disorders. Clinical Descriptions and Diagnostic Guidelines (ICD-10). From a perspective of primary care services, this unmet diagnostic need is deplorable, as the main mode of presenting a depression is by reporting somatic symptoms. This somatic form of presentation, however, significantly contributes to low rates of recognition in primary care. A diagnostic challenge may be seen in the differentiation of a depression with prevailing somatic symptoms from anxiety, somatoform disorders, and medical conditions. When somatic symptoms, particularly painful physical conditions, accompany the already debilitating psychiatric and behavioral symptoms of depression, the course of the illness may be more severe, implying a higher risk of early relapse, chronicity suicide, or mortality due to other natural causes, the economic burden increases considerably, the functional status may be hampered heavily, and health-related quality of life may be lowered dramatically. The neurobiological underpinnings of somatic symptoms in depression may guide more promising treatment approaches. PMID:16889108

    Background Refractory gastroesophageal reflux disease (GERD) may deteriorate patient quality of life (QOL) despite proton pump inhibitor (PPI) therapy. Material/Methods Nineteen Japanese institutions were surveyed to determine the clinical characteristics and QOL of patients with refractory GERD. Those patients treated with a conventional PPI were switched to 20 mg esomeprazole for 4 weeks. Symptoms and QOL were assessed using Global Overall Symptom and Gastrointestinal Symptom Rating Scale (GSRS) questionnaires at baseline and at 2 and/or 4 weeks of esomeprazole treatment. Results Of 120 patients who completed the survey, 58 (48.3%) had refractory GERD. Of these, 69.0% were aged ≥65 years, 79.3% were prescribed a PPI at a standard or high dose, and 22.4% were prescribed a PPI together with another drug. After switching to esomeprazole, patients reported significant improvements in heartburn, acid regurgitation, and excessive belching at 2 weeks using a symptom diary, as well as the total score, reflux, abdominal pain, and indigestion, which were assessed using the GSRS at 4 weeks. Conclusions About half of Japanese patients with GERD may be refractory to conventional PPIs. Their reflux-related symptoms are often severe and may impair QOL. Switching to esomeprazole could be used to improve their symptoms and QOL. PMID:26719012

    Background Panic disorder (PD) is highly comorbid with major depressive disorder (MDD) with potential impact on patient-reported outcomes of quality of life (QOL), functioning, and depressive symptom severity Methods Using data from the sequenced treatment alternatives to relieve depression (STAR*D) trial, we compared entry and post-SSRI-treatment QOL, functioning, and depressive symptom severity scores in MDD patients with comorbid PD (MDD+PD) to MDD patients without PD (MDDnoPD). We also compared pre- and posttreatment proportions of patients with severe impairments in quality of life and functioning. Results MDD+PD patients experienced significantly lower QOL and functioning and more severe depressive symptoms than MDDnoPD patients at entry. Following treatment with citalopram, both groups showed significant improvements, however, nearly 30–60% of patients still suffered from severe quality of life and functioning impairments. MDD+PD patients exited with lower QOL and functioning than MDDnoPD patients, a difference that became statistically insignificant after adjusting for baseline measures of depressive symptom severity, functioning, and QOL, comorbid anxiety disorders (PTSD, GAD, social, and specific phobias), age, and college education. Conclusions Functional outcomes using QOL and functioning measures should be utilized in treating and researching MDD so that shortfalls in traditional treatment can be identified and additional interventions can be designed to address severe baseline QOL and functioning deficits in MDD comorbid with PD.

    Objective To determine whether a one-off, baseline measure of depression and anxiety in a primary care, coronary heart disease (CHD) population predicts ongoing symptoms, costs, and quality of life across a 3-year follow-up. Design Longitudinal cohort study. Setting 16 General Practice surgeries across South-East London Participants 803 adults (70% male, mean age 71 years) contributing up to 7 follow-up points. Main outcome measures Ongoing reporting of symptoms, health care costs, and quality of life. Results At baseline, 27% of the sample screened positive for symptoms of depression and anxiety, as measured by the Hospital Anxiety and Depression Scale (HADS). The probability of scoring above the cut-off throughout the follow-up was 71.5% (p<0.001) for those screening positive at baseline, and for those screening negative, the probability of scoring below the cut-off throughout the follow-up was 97.6% (p<0.001). Total health care costs were 39% higher during follow-up for those screening positive (p<0.05). Quality of life as measured by the SF-12 was lower on the mental component during follow-up for those screening positive (-0.75, CI -1.53 to 0.03, p = 0.059), and significantly lower on the physical component (-4.99, CI -6.23 to -.376, p<0.001). Conclusions A one-off measure for depression and anxiety symptoms in CHD predicts future symptoms, costs, and quality of life over the subsequent three-years. These findings suggest symptoms of depression and anxiety in CHD persist throughout long periods and are detrimental to a patient’s quality of life, whilst incurring higher health care costs for primary and secondary care services. Screening for these symptoms at the primary care level is important to identify and manage patients at risk of the negative effects of this comorbidity. Implementation of screening, and possible collaborative care strategies and interventions that help mitigate this risk should be the ongoing focus of researchers and policy

    We report an all-fiberized SBS-based high repetition rate sub-nanosecond Yb fiber laser for supercontinuum generation. The high repetition rate ns laser pulses were produced from a fiber Bragg grating (FBG)-constructed fiber laser cavity consisting of a piece of double cladding Yb fiber as the gain medium and a short piece of Bi/Cr-doped fiber as a saturable absorber (SA). By optimizing the fiber length of the Bi/Cr-doped fiber and the reflectivity of the FBG, the Q-switching state of the fiber laser can be adjusted so that the energy storing condition within the fiber cavity can assure the start of stimulated Brillouin scattering (SBS) and as a result, compress the laser pulse duration. The fiber laser had an average laser power output of 1.2 W at 1064 nm with pulse repetition rate of about 80 kHz, almost four times the reported results. The pulse duration was about 1 ns with peak power of about 15 kW. After one stage of amplification, the laser power was raised to about 3 W and was used to pump a 20 m long photonic crystal fiber (PCF). Supercontiuum (SC) laser output was obtained with average power up to 1.24 W and spectrum spanning from 550 to 2200 nm.

  15. Patients with unexplained physical symptoms have poorer quality of life and higher costs than other patient groups: a cross-sectional study on burden

    PubMed Central

    2013-01-01

    Background To determine whether healthcare resources are allocated fairly, it is helpful to have information on the quality of life (QoL) of patients with Unexplained Physical Symptoms (UPS) and on the costs associated with them, and on how these relate to corresponding data in other patient groups. As studies to date have been limited to specific patient populations with UPS, the objective of this study was to assess QoL and costs in a general sample of patients with UPS using generic measures. Methods In a cross-sectional study, 162 patients with UPS reported on their QoL, use of healthcare resources and lost productivity in paid and unpaid work. To assess QoL, the generic SF-36 questionnaire was used, from which multidimensional quality-of-life scores and a one-dimensional score (utility) using the SF-6D scorings algorithm were derived. To assess costs, the TiC-P questionnaire was used. Results Patients with UPS reported a poor QoL. Their QoL was mostly decreased by limitations in functioning due to physical health, and the least by limitations in functioning due to emotional problems. The median of utilities was 0.57, and the mean was 0.58 (SD = .09). The cost for the use of healthcare services was estimated to be €3,123 (SD = €2,952) per patient per year. This cost was enlarged by work-related costs: absence from work (absenteeism), lower on-the-job productivity (presenteeism), and paid substitution of domestic tasks. The resulting mean total cost was estimated to be €6,815 per patient per year. Conclusions These findings suggest that patients with UPS have a high burden of disease and use a considerable amount of healthcare resources. In comparison with other patient groups, the QoL values of patients with UPS were among the poorest and their costs were among the highest of all patient groups. The burden for both patients and society helps to justify the allocation of sufficient resources to effective treatment for patients with UPS. Trial

    We present X-ray observations of the close binary nucleus of the planetary nebula SBS 1150+599A obtained with the XMM-Newton satellite. Only one component of the binary can be observed in optical-UV. New X-ray observations show that the previously invisible component is a very hot compact star. This finding allows us to deduce rough values for the basic parameters of the binary. With a high probability the total mass of the system exceeds Chandrasekhar limit and makes the SBS1150+599A one of the best candidate for a supernova type Ia progenitor.

    1999-05-15

    Composite membranes of a block copolymer of styrene and butadiene (S-B-S) were cast on highly porous, hydrophobic thin films of PTFE and used for the separation and recovery of volatile organic compounds (VOCs) from aqueous solutions by pervaporation. Trichloroethane, trichloroethylene, and toluene were the VOCs selected for testing the efficacy of these membranes. An analysis of the pervaporation data showed that the liquid film boundary layer offered the main mass transfer resistance to permeation. The separation factor for the VOCs was as high as 5000 at near-ambient temperatures but decreased substantially at higher temperatures. The water flux was practically independent of the solute concentration. But it increased more rapidly with an increase in temperature as compared to the organic flux, thereby reducing the separation factor. Also, the separation of a multicomponent mixture from the aqueous feed could be predicted well from single-component data.

    All-solid-state sodium batteries, using solid electrolyte and abundant sodium resources, show great promise for safe, low-cost, and large-scale energy storage applications. The exploration of novel solid electrolytes is critical for the room temperature operation of all-solid-state Na batteries. An ideal solid electrolyte must have high ionic conductivity, hold outstanding chemical and electrochemical stability, and employ low-cost synthetic methods. Achieving the combination of these properties is a grand challenge for the synthesis of sulfide-based solid electrolytes. Design of the solid electrolyte Na3 SbS4 is described, realizing excellent air stability and an economic synthesis based on hard and soft acid and base (HSAB) theory. This new solid electrolyte also exhibits a remarkably high ionic conductivity of 1 mS cm(-1) at 25 °C and ideal compatibility with a metallic sodium anode. PMID:27246874

    We present the results of our broadband study of the γ-ray emitting narrow line Seyfert 1 (NLSy1) galaxy SBS 0846+513 (z = 0.585). This includes multiband flux variations, γ-ray spectral analysis, broadband spectral energy distribution (SED) modeling, and intranight optical variability (INOV) observations carried out over six nights between 2012 November and 2013 March using the 2 m Himalayan Chandra Telescope and the 1.3 m telescope at Devasthal, India. Multiple episodes of flaring activity are seen in the γ-ray light curve of the source which are also reflected in the observations at lower frequencies. A statistically significant curvature is noticed in the seven years averaged γ-ray spectrum, thus indicating its similarity with powerful flat spectrum radio quasars (FSRQs). Modeling the SEDs with a one-zone leptonic emission model hints that the optical UV spectrum is dominated by synchrotron radiation, whereas inverse Compton scattering of broad line region photons reproduces the γ-ray part of the SEDs. The source was found to be variable on all the six nights of optical observations with a variation of ∼0.3 mag within a single night, coinciding with a high γ-ray activity state. The observed large amplitude INOV clearly indicates the presence of a closely aligned beamed relativistic jet in SBS 0846+513. Our broadband study supports the recent claims in literature that γ-ray emitting NLSy1 galaxies are similar to blazars and constitute the low black hole mass counterparts to FSRQs.

    The perception of the indoor environmental quality (IEQ) through questionnaires in conjunction with in-field measurements related to the indoor air quality (IAQ), the thermal comfort and the lighting environment were studied in nine naturally ventilated schools of Athens, Greece. Cluster analysis was carried out in order to determine the ranges of indoor air pollutants, temperature (T), relative humidity (RH), and ventilation rates at which the students were satisfied with the indoor environment. It was found that increased levels of particulate matter did not have a negative effect on students' perception while students seemed to link the degradation of IAQ with temperature variations. Statistically significant correlations were further found between measurement results and students' perception of the IEQ. Students' sick building syndrome (SBS) symptoms and performance of schoolwork were also investigated as a function of the levels of indoor air pollutants and ventilation, and there were found significant positive correlations between particulate matter (PM) and certain health symptoms. Students' learning performance seemed to be affected by the ventilation rates and carbon dioxide (CO₂) concentrations while certain health effects positively correlated to the levels of PM and CO₂. The energy consumption of schools was rather low compared to other national findings, and both the electricity and oil consumption for heating positively correlated to the levels of indoor air pollutants.

    Depressive symptoms are very common in chronic conditions. This is true so for neurodegenerative diseases. A number of patients with cognitive decline and dementia due to Alzheimer’s disease and related conditions like Parkinson’s disease, Lewy body disease, vascular dementia, frontotemporal degeneration amongst other entities, experience depressive symptoms in greater or lesser grade at some point during the course of the illness. Depressive symptoms have a particular significance in neurological disorders, specially in neurodegenerative diseases, because brain, mind, behavior and mood relationship. A number of patients may develop depressive symptoms in early stages of the neurologic disease, occurring without clear presence of cognitive decline with only mild cognitive deterioration. Classically, depression constitutes a reliable diagnostic challenge in this setting. However, actually we can recognize and evaluate depressive, cognitive or motor symptoms of neurodegenerative disease in order to establish their clinical significance and to plan some therapeutic strategies. Depressive symptoms can appear also lately, when the neurodegenerative disease is fully developed. The presence of depression and other neuropsychiatric symptoms have a negative impact on the quality-of-life of patients and caregivers. Besides, patients with depressive symptoms also tend to further decrease function and reduce cognitive abilities and also uses to present more affected clinical status, compared with patients without depression. Depressive symptoms are treatable. Early detection of depressive symptoms is very important in patients with neurodegenerative disorders, in order to initiate the most adequate treatment. We review in this paper the main neurodegenerative diseases, focusing in depressive symptoms of each other entities and current recommendations of management and treatment. PMID:26301229

Classically, depression constitutes a reliable diagnostic challenge in this setting. However, actually we can recognize and evaluate depressive, cognitive or motor symptoms of neurodegenerative disease in order to establish their clinical significance and to plan some therapeutic strategies. Depressive symptoms can appear also lately, when the neurodegenerative disease is fully developed. The presence of depression and other neuropsychiatric symptoms have a negative impact on the quality-of-life of patients and caregivers. Besides, patients with depressive symptoms also tend to further decrease function and reduce cognitive abilities and also uses to present more affected clinical status, compared with patients without depression. Depressive symptoms are treatable. Early detection of depressive symptoms is very important in patients with neurodegenerative disorders, in order to initiate the most adequate treatment. We review in this paper the main neurodegenerative diseases, focusing in depressive symptoms of each other entities and current recommendations of management and treatment. PMID:26301229

    Home health care agencies are increasingly taking care of sicker, older patients with greater comorbidities. However, they are unequipped to appropriately manage these older adults, particular persons living with dementia (PLWD). We therefore developed the Dementia Symptom Management at Home (DSM-H) Program, a bundled interprofessional intervention, to improve the care confidence of providers, and quality of care delivered to PLWD and their caregivers. We implemented the DSM-H with 83 registered nurses, physical therapists, and occupational therapists. Overall, there was significant improvement in pain knowledge (5.9%) and confidence (26.5%), depression knowledge (14.8%) and confidence (36.1%), and neuropsychiatric symptom general knowledge (16.8%), intervention knowledge (20.9%), attitudes (3.4%) and confidence (27.1%) at a statistical significance of (P < .0001). We also found significant differences between disciplines. Overall, this disseminable program proved to be implementable and improve clinician's knowledge and confidence in caring for PLWD, with the potential to improve quality of care and quality of life, and decrease costs.

    By comparing the impact of established laser smoothing techniques like Random Phase Plates (RPP) and Smoothing by Spectral Dispersion (SSD) to the concept of "Spike Trains of Uneven Duration and Delay" (STUD pulses) on the amplification of parametric instabilities in laser-produced plasmas, we show with the help of numerical simulations, that STUD pulses can drastically reduce instability growth by orders of magnitude. The simulation results, obtained with the code Harmony in a nonuniformly flowing mm-size plasma for the Stimulated Brillouin Scattering (SBS) instability, show that the efficiency of the STUD pulse technique is due to the fact that successive re-amplification in space and time of parametrically excited plasma waves inside laser hot spots is minimized. An overall mean fluctuation level of ion acoustic waves at low amplitude is established because of the frequent change of the speckle pattern in successive spikes. This level stays orders of magnitude below the levels of ion acoustic waves excited in hot spots of RPP and SSD laser beams.

    Current status of SBS PCM based IFE approach proposed recently as an alternative to the IFE classical approach is presented. This technology is of particular importance to the direct drive scheme taking care of automatic self-navigation of every individual laser beam on the injected pellets with no need for any final optics adjustment. Conceptual design of one typical laser driver is shown and its features discussed. In comparison with the earlier design an upgraded scheme was developed with the low energy illumination laser beam (glint) entering the reactor chamber through the same entrance window as used by the corresponding high energy irradiation laser beam. Results of experimental verification of this improved design are reported. In these experiments for the fist time a complete setup including the pellet (realized by the static steel ball) was employed. The pellet survival conditions in the period between its low energy illumination and subsequent high energy irradiation were studied and the upper limits on the allowed energies absorbed were found for both DD and DT fuels.

    All-solid-state sodium batteries, using abundant sodium resources and solid electrolyte, hold much promise for safe, low cost, large-scale energy storage. To realize the practical applications of all solid Na-ion batteries at ambient temperature, the solid electrolytes are required to have high ionic conductivity, chemical stability, and ideally, easy preparation. Ceramic electrolytes show higher ionic conductivity than polymers, but they often require extremely stringent synthesis conditions, either high sintering temperature above 1000 C or long-time, low-energy ball milling. Herein, we report a new synthesis route for Na3SbS4, a novel Na superionic conductor that needs much lower processing temperature below 200 Cmore » and easy operation. This new solid electrolyte exhibits a remarkable ionic conductivity of 1.05 mS cm-1 at 25 °C and is chemically stable under ambient atmosphere. In conclusion, this synthesis process provides unique insight into the current state-of-the-art solid electrolyte preparation and opens new possibilities for the design of similar materials.« less

    Background Ingestion of AndoSanTM, based on the mushroom Agaricus blazei Murill, has previously shown an anti-inflammatory effect through reduction of pro-inflammatory cytokines in healthy individuals and patients with Crohn’s disease (CD). In this randomized single-blinded placebo-controlled study we examined whether intake of AndoSanTM also resulted in clinical effects. Methods and Findings 50 patients with symptomatic CD were randomized for oral daily consumption of AndoSanTM or placebo for a 21-day experimental period, in this per-protocol study. Patients reported validated scores for symptoms, fatigue and health related quality of life (HRQoL) at days 0, 14 and 21. Fecal calprotectin and general blood parameters were also analyzed. In the AndoSanTM group (n = 25) symptoms improved from baseline (day 0) to days 14 and 21, with respective mean scores (95% CI) of 5.52 (4.64–6.40), 4.48 (3.69–5.27) and 4.08 (3.22–4.94) (p<0,001). We found significant improvements in symptom score for both genders in the AndoSanTM group, and no significant changes in the placebo (n = 25) group. There were however no significant differences between the groups (p = 0.106), although a marginal effect in symptom score for men (p = 0.054). There were comparable improvements in physical, mental and total fatigue for both groups. HRQoL versus baseline were at day 21 improved for bodily pain and vitality in the AndoSanTM group and for vitality and social functioning in the placebo group. No crucial changes in general blood samples and fecal calprotectin were detected. Conclusions The results from this single-blinded randomized clinical trial shows significant improvement on symptoms, for both genders, in the AndoSanTM group, but no significant differences between the study groups. The results on fatigue, HRQoL, fecal calprotectin and blood samples were quite similar compared with placebo. The patients did not report any harms or unintended effects of AndoSanTM.

    Oxidative stress plays a key role in the development of chronic pulmonary complications of sulfur mustard (SM). Curcuminoids are polyphenols with documented safety and antioxidant activity. The present study aimed to investigate the efficacy of short-term supplementation with curcuminoids (co-administered with piperine to enhance the bioavailability of curcuminoids) in alleviating systemic oxidative stress and clinical symptoms, and improvement of health-related quality of life (HRQoL) in subjects suffering from chronic pulmonary complications due to SM exposure who are receiving standard respiratory treatments. Eighty-nine subjects were recruited to this randomized double-blind placebo-controlled trial, being randomly allocated to either curcuminoids (1500 mg/day) + piperine (15 mg/day) combination (n = 45) or placebo (n = 44) for a period of 4 weeks. High-resolution computed tomography suggested the diagnosis of bronchiolitis obliterans in all subjects. Efficacy measures were changes in serum levels of reduced glutathione (GSH) and malonedialdehyde (MDA). The severity and frequency of respiratory symptoms and HRQoL were also assessed using St. George respiratory Questionnaire (SGRQ) and COPD Assessment Test (CAT) indices. Serum levels of GSH were increased whilst those of MDA decreased by the end of trial in both groups. Likewise, there were significant improvements in the total as well as subscale (symptoms, activity and impact) SGRQ and CAT scores in both groups. However, comparison of magnitude of changes revealed a greater effect of curcuminoids-piperine combination compared to placebo in elevating GSH, reducing MDA and improving CAT and SGRQ (total and subscale) scores (p < 0.001). Regarding the promising effects of curcuminoids on the measures of systemic oxidative stress, clinical symptoms and HRQoL, these phytochemicals may be used as safe adjuvants in patients suffering from chronic SM-induced pulmonary complications who are receiving standard treatments

    Linearized self-consistent Boltzmann transport equation (BTE), utilizing interatomic force constants (IFCs) obtained via compressive sensing lattice dynamics (CSLD), is used to study the lattice thermal conductivity (κl) of Cu3SbS4, Cu3SbSe4 and their solid solutions. With these IFCs we obtain bulk lattice thermal conductivity in good agreement with experimental measurements. We also compare Cu3SbS4andCu3SbSe4 with respect to Grüneisen parameter, group velocity, phonon lifetime, mean free path and cumulative κl. All the analysis indicates that (1) slightly larger group velocity and lifetime of acoustic modes found in Cu3SbS4 lead to larger κl compared with Cu3SbSe4 over the whole temperature range. Contributions from optical modes to κl for both compounds are about 25% at temperature higher than 300K. This large portion of κl can not be neglected if one aims to predict accurate κl; (2) Nanostructures with length less than 10nm can effectively reduce κl by about 80% for both of the compounds; (3) solid solution of two compounds can effectively reduce κl as much as 40% at room temperature.

    All-solid-state sodium-ion batteries that operate at room temperature are attractive candidates for use in large-scale energy storage systems. However, materials innovation in solid electrolytes is imperative to fulfill multiple requirements, including high conductivity, functional synthesis protocols for achieving intimate ionic contact with active materials, and air stability. A new, highly conductive (1.1 mS cm(-1) at 25 °C, Ea =0.20 eV) and dry air stable sodium superionic conductor, tetragonal Na3 SbS4 , is described. Importantly, Na3 SbS4 can be prepared by scalable solution processes using methanol or water, and it exhibits high conductivities of 0.1-0.3 mS cm(-1) . The solution-processed, highly conductive solidified Na3 SbS4 electrolyte coated on an active material (NaCrO2 ) demonstrates dramatically improved electrochemical performance in all-solid-state batteries.

    We present a comprehensive experimental study of the technique of Longitudinal Mode Filling (LMF) applied to the reduction of Stimulated Brillouin Scattering (SBS), in Ytterbium Doped Fibre Amplifiers (YDFA) at the wavelength of 1064 nm. Pulse durations and Mode Field Diameters (MFD) lie in the ranges of 10 - 100 ns and 10 - 35 μm, respectively. Input pulse-shaping is implemented by means of direct current modulation in multimode Laser-Diode seeds. This evidences a number of interests in the development of robust and low cost Master Oscillator Power Amplifiers (MOPA). Highly energetic, but properly shaped, nanosecond pulses may be produced this way without any need of additional electro-optical means for in-line phase and amplitude modulation. Seeds consist of Distributed Feed- Back (DFB) and Fibre Bragg Gratings (FBG) with different fibre lengths. We demonstrate the benefit of LMF with properly controlled mode spacing, in combination with chirp effects due to fast current transients in the semiconductors, in order to deal with SBS thresholds in the range of a few to some hundred μJ. The variations of the SBS threshold are discussed versus the number of longitudinal modes, the operating conditions of the selected seed and pulse-shaping conditions.

    The influence of the strictive self-interaction on the threshold and quality of phase conjugation in the course of stimulated Brillouin scattering (SBS) was investigated numerically in the linear approximation for steady-state linearly polarised pumping. The calculations were carried out for the three-dimensional case of a Gaussian pump beam and a beam representing a superposition of 10 x 10 Hermitian - Gaussian modes with random phases. It was found that in the case of a Gaussian beam the growth of the strictive aberrations leads to a significant reduction of the SBS threshold but has little influence on the conjugation quality. In the case of a pump beam with a divergence exceeding the diffraction limit such growth of the strictive aberrations results (on the average) in lowering the SBS threshold and in deterioration of the conjugation quality. The calculated results depend strongly on the specific phase combination of the superposed modes. (nonlinear optical phenomena)

    There are few studies on rhinitis and sick building syndrome (SBS) among students in tropical countries. We studied associations between levels of five fungal DNA sequences, two mycotoxins (sterigmatocystin and verrucarol) and cat allergen (Fel d 1) levels in schools and rhinitis and other weekly SBS symptoms in the students. Fungal DNA was measured by quantitative PCR and cat allergen by ELISA. Pupils (N = 462) from eight randomly selected schools in Johor Bahru, Malaysia participated (96%). Dust samples were collected by cotton swabs and Petri dishes exposed for one week. None of the schools had a mechanical ventilation system, but all classrooms had openable windows that were kept open during lectures and indoor CO2 levels were low (mean 492 ppm; range 380-690 ppm). Weekly nasal symptoms (rhinitis) (18.8%), ocular (11.6%), throat (11.1%), dermal symptoms, headache (20.6%) and tiredness (22.1%) were common. Total fungal DNA in swab samples was associated with rhinitis (p = 0.02), ocular symptoms (p = 0.009) and tiredness (p = 0.001). There were positive associations between Aspergillus versicolor DNA in Petri dish samples, ocular symptoms (p = 0.02) and tiredness (p = 0.001). The level of the mycotoxin verrucarol (produced by Stachybotrys chartarum) in swab samples was positively associated with tiredness (p = 0.04). Streptomyces DNA in swab samples (p = 0.03) and Petri dish samples (p = 0.03) were negatively associated with tiredness. In conclusion, total fungal contamination, measured as total fungal DNA) in the classrooms, Aspergillus versicolor and verrucarol can be risk factors for rhinitis and SBS symptoms among students in the tropical country Malaysia.

    Chronic idiopathic urticaria (CIU) is a frequently disabling disease with a negative influence on the quality of life, and can cause psychopathological symptoms, such as anxiety. Our aim is to study further anxiety symptoms on CIU patients. Both CIU patients and the control group were studied by means of validated scales for psychopathology symptoms, psychological variables and quality of life. In this study, we reported high levels of anxiety symptoms. We found statistically significant correlations between anxiety symptoms, some personality dimensions, insecure attachment styles, alexithymia and with some quality of life dimensions. CIU patients exhibit high levels of psychological distress that could potentiate difficulties at several domains, namely social, emotional, general health perception and interpersonal relationships.

    Introduction Atrial fibrillation (AF) is the most common cardiac arrhythmia, with an estimated prevalence of 1.5–2%. It is an independent risk factor for ischaemic stroke and is estimated to cause about 20–25% of all stroke cases. AF has a great impact on health-related quality of life (HRQoL); however, one unresolved issue related to AF is the wide variation in its symptoms. Methods and analysis The symptom burden, metabolic profile, ultrasound findings, rhythm, neurohormonal activation, haemodynamics and HRQoL in patients with AF (Symptom burden, Metabolic profile, Ultrasound findings, Rhythm, neurohormonal activation, haemodynamics and health-related quality of life in patients with atrial Fibrillation, SMURF) study is a prospective observational, cohort study, with a randomised interventional part. The aim of the study is to investigate, in patients with AF, the relationship between symptom burden and metabolic aspects, atrial function and different neurohormones, and the effect of radiofrequency ablation (RFA). The interventional part of the study will give an insight into the neurohormonal and intracardiac pressure changes directly after initiation of AF. Consecutive patients with symptomatic AF accepted for treatment with RFA for the first time at Linköping University Hospital are eligible for participation. The enrolment started in January 2012, and a total of 200 patients are to be included into the study, with 45 of them being enrolled into the interventional study with initiation of AF. The sample size of the interventional study is based on a small pilot study with 5 patients induced to AF while 2 served as controls. The results indicated that, in order to find a statistically significant difference, there was a need to include 28 patients; for safety reasons, 45 patients will be included. Ethics and dissemination The SMURF study is approved by the Regional Ethical Review Board at the Faculty of Health Sciences, Linköping, Sweden. The results will

    We present three complete seasons and two half-seasons of Sloan Digital Sky Survey (SDSS) r-band photometry of the gravitationally lensed quasar SBS 0909+532 from the U.S. Naval Observatory, as well as two seasons each of SDSS g-band and r-band monitoring from the Liverpool Robotic Telescope. Using Monte Carlo simulations to simultaneously measure the system's time delay and model the r-band microlensing variability, we confirm and significantly refine the precision of the system's time delay to {Delta}t{sub AB} = 50{sub -4}{sup +2} days, where the stated uncertainties represent the bounds of the formal 1{sigma} confidence interval. There may be a conflict between the time delay measurement and a lens consisting of a single galaxy. While models based on the Hubble Space Telescope astrometry and a relatively compact stellar distribution can reproduce the observed delay, the models have somewhat less dark matter than we would typically expect. We also carry out a joint analysis of the microlensing variability in the r and g bands to constrain the size of the quasar's continuum source at these wavelengths, obtaining log {l_brace}(r{sub s,r}/cm)[cos i/0.5]{sup 1/2}{r_brace} = 15.3 {+-} 0.3 and log {l_brace}(r{sub s,g}/cm)[cos i/0.5]{sup 1/2}{r_brace} = 14.8 {+-} 0.9, respectively. Our current results do not formally constrain the temperature profile of the accretion disk but are consistent with the expectations of standard thin disk theory.

    The Optimizing Patient Transfers, Impacting Medical Quality, and Improving Symptoms: Transforming Institutional Care (OPTIMISTIC) project aims to reduce avoidable hospitalizations of long-stay residents enrolled in 19 central Indiana nursing facilities. This clinical demonstration project, funded by the Centers for Medicare and Medicaid Services Innovations Center, places a registered nurse in each nursing facility to implement an evidence-based quality improvement program with clinical support from nurse practitioners. A description of the model is presented, and early implementation experiences during the first year of the project are reported. Important elements include better medical care through implementation of Interventions to Reduce Acute Care Transfers tools and chronic care management, enhanced transitional care, and better palliative care with a focus on systematic advance care planning. There were 4,035 long-stay residents in 19 facilities enrolled in OPTIMISTIC between February 2013 and January 2014. Root-cause analyses were performed for all 910 acute transfers of these long stay residents. Of these transfers, the project RN evaluated 29% as avoidable (57% were not avoidable and 15% were missing), and opportunities for quality improvement were identified in 54% of transfers. Lessons learned in early implementation included defining new clinical roles, integrating into nursing facility culture, managing competing facility priorities, communicating with multiple stakeholders, and developing a system for collecting and managing data. The success of the overall initiative will be measured primarily according to reduction in avoidable hospitalizations of long-stay nursing facility residents. PMID:25537789

    In an environmental intervention study in public housing, we examined monthly Juniper Paediatric Asthma Quality of Life (QOL) Questionnaires for 51 children. Longitudinal analysis and spline models were used to identify time periods with significant improvements in QOL to inform judgments about causality. We found significant improvements in QOL, with moderate improvements before environmental interventions, increased rates of improvement immediately after, and reduced rates more than 5 months post-intervention. Effect modification analyses identified high-risk subpopulations and emphasized the importance of environmental, social, and economic conditions. Our results demonstrate the value of longitudinal techniques in evaluating the benefits of environmental interventions for asthma. PMID:16801137

In this randomized single-blinded placebo controlled study we examined whether intake of AndoSan™ also resulted in clinical effects. Methods and Findings 50 patients with symptomatic ulcerative colitis were block-randomized and blinded for oral daily intake of AndoSan™ or placebo for the 21 days’ experimental period. The patients reported scores for symptoms, fatigue and health related quality of life (HRQoL) at days 0, 14 and 21. Fecal calprotectin and general blood parameters were also analyzed. In the AndoSan™ group (n = 24) symptoms improved from baseline (day 0) to days 14 and 21, with respective mean scores (95% CI) of 5.88 (4.92–6.83), 4.71 (3.90–5.52) (p = 0.002) and 4.50 (3.70–5.30) (p = 0.001).

When comparing the two study groups using mixed model statistics, we found significant better scores for the AndoSan™-patients. HRQoL for dimensions bodily pain, vitality, social functioning and mental health improved in the AndoSan™ group. There were no alterations in general blood samples and fecal calprotectin. Conclusions Beneficiary effects on symptoms, fatigue and HRQoL from AndoSan™ consumption were demonstrated in this per-protocol study, supporting its use as a supplement to conventional medication for patients with mild to moderate symptoms from ulcerative colitis. The patients did not report any harms or unintended effects of AndoSan™ in this study. Trial Registration ClinicalTrials.gov NCT01496053 PMID:26933886

  8. [Depressive symptoms and negative symptoms during schizophrenia].

    Taking into account the wellknown frequency of depressive and extrapyramidal symptoms in schizophrenia and the rare studies about their evolution, several questions can be raised: How do these different symptoms move? Are there specific characters of each of them? First, stability of negative symptoms evaluated by the Scale for the Assessment of Negative Symptoms (SANS) was studied among 57 schizophrenic patients at admission and at discharge. The course of negative symptoms was compared to that of depressive MADRS (Montgomery et Asberg Depression Rating Scale) and akinetic symptoms (Extrapyramidal Symptom Rating Scale). All the subscores of the SANS decreased significantly but 4 items belonging to the affective flattening subscale and one item belonging to the alogia subscale did not vary significantly, showing the necessity of taking into account the individual items of the SANS rather than the subscale scores to evaluate the course of negative symptoms. Changes in all the SANS subscores except the alogia and anhedonia subscores were associated with variations in scores of other scales. Correlations between the changes of negative symptoms and the changes of depressive symptoms showed the necessity to do more specific scales, for example, scales for depression in schizophrenia. Langlois-Théry et al. (1994) evaluated among 53 schizophrenic patients stabilized with neuroleptic treatment, depressive symptomatology with Echelle de Ralentissement Dépressif (ERD, Widlöcher, 1983) and MADRS, negative symptomatology (Positive and Negative Syndrome Scale) and akinesia (ESRS), to determinate whether ERD composed of 3 subscores (motor, ideic and subjective) could be able to evaluate the depressive symptomatology, independently of the measures of negative and akinetic symptomatology.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:7628337

    Treating negative symptoms of schizophrenia is a major issue and a challenge for the functional and social prognosis of the disease, to which they are closely linked. First- and second-generation antipsychotics allow a reduction of all negative symptoms. The hope of acting directly on primary negative symptoms with any antipsychotic is not supported by the literature. However, the effectiveness of first- and second-generation antipsychotics is demonstrated on secondary negative symptoms. PMID:26776390

    History of childhood trauma (CT) is highly prevalent and may lead to long-term consequences on physical and mental health. This study investigated the independent association of CT with symptoms of adult depression and posttraumatic stress disorder (PTSD), mental and physical health-related quality of life (HRQoL), as well as current tobacco consumption and alcohol abuse in a large homogenous cohort of 1254 never-deployed, young male Marines enrolled in the Marine Resiliency Study. Independent effects of CT history, number and type of CT on outcomes were analyzed using hierarchical multivariate logistic regression models. Our results suggested dose-dependent negative effect of an increasing number of trauma types of CT on depression, PTSD and HRQoL. Experience of single CT type demonstrated overall weak effects, while history of multiple CT types distinctively increased the likelihood of adult PTSD symptomology (OR: 3.1, 95% CI: 1.5-6.2), poor mental (OR: 2.3, 95% CI: 1.7-3.1) and physical HRQoL (OR: 1.4, 95% CI: 1.1-1.9). Risk for depression symptoms was similar for both single and multiple CT (OR: 2.2, 95% CI: 1.3-3.8 and OR: 2.1, 95% CI: 1.2-3.5 respectively). CT history had no effects on current tobacco use and alcohol abuse. Our study thus provides evidence for substantial additive effect of different CT types on adult mental and physical health with increasing levels of exposure. PMID:25139009

    2012-12-01

    The presence of a relativistic jet in some radio-loud Narrow-Line Seyfert 1s (NLSy1) galaxies, first suggested by their variable radio emission and the flat radio spectra, is now confirmed by the Fermi-LAT detection of five NLSy1s in γ rays. In particular, a strong γ-ray flare from SBS 0846+513 was observed in 2011 June by Fermi-LAT reaching a γ-ray luminosity (0.1-300 GeV) of ~1048 erg s-1, comparable to that of bright flat spectrum radio quasars. Apparent superluminal velocity in the jet was inferred from 2011-2012 VLBA images, suggesting the presence of a highly relativistic jet. Both the power released by this object during the flaring activity and the apparent superluminal velocity are strong indicators of the presence of a relativistic jet as powerful as those in blazars. In addition, variability and spectral properties in radio and γ-ray bands indicate a blazar-like behaviour, suggesting that, except for some distinct optical characteristics, SBS 0846+513 could be considered as a young blazar at the low end of the blazar's black hole mass distribution.

    The aim of the present experiment was to test the effects of a wet preservation of triticale contaminated mainly with deoxynivalenol (DON) with sodium metabisulphite (Na2S2O5, SBS) on growth performance, liver function, clinical-chemical plasma parameters and organ histopathology of piglets. For this purpose both the uncontaminated control triticale and the DON contaminated triticale were included in the piglet diet either untreated (CON, FUS) or SBS-treated (CON-SBS, FUS-SBS) and fed for 28 d starting from weaning. The dietary concentrations of DON and DON sulfonate (DONS), the DON derivative resulting from the SBS treatment, amounted to 0.156, 0.084, 2.312 and 0.275 mg DON per kg CON, CON-SBS, FUS and FUS-SBS diet, and to <0.05, <0.05, <0.05 and 1.841 mg/kg diet, respectively. Feeding the FUS diet significantly reduced the feed intake compared to the other three groups as indicated by the significant interactions between triticale source and SBS treatment when the whole experimental period of 28 d was considered (p = 0.014) while live weight gain and feed to gain ratio remained unaffected. The total plasma protein concentration was significantly depressed due to feeding the contaminated diets whereas SBS treatment exerted an increasing effect at the same time (45.4, 49.5, 40.7 and 46.5 g/l for piglets fed the CON, CON-SBS, FUS and FUS-SBS diet, respectively). The liver function was tested by the 13C-methacetin breath test (MBT) allowing evaluation of the cytochrome P4501A2 activity. MBT results, expressed as cumulative percentage dose recovery after 360 min (cPDR360) revealed a slight stimulation of liver function due to SBS treatment (p = 0.052) (37.5, 39.4, 37.4 and 55.1% for piglets fed the CON, CON-SBS, FUS and FUS-SBS diet, respectively). Liver weight and histopathological scoring were only weakly related to the MBT results. Further histopathological examinations of kidneys, pancreas and heart revealed no treatment effects. It was concluded that the SBS

  1. Indoor carbon dioxide concentrations and sick building syndrome symptoms in the BASE study revisited: Analyses of the 100 building dataset

    2002-02-01

    In previously published analyses of the 41-building 1994-1996 USEPA Building Assessment Survey and Evaluation (BASE) dataset, higher workday time-averaged indoor minus outdoor CO{sub 2} concentrations (dCO{sub 2}) were associated with increased prevalence of certain mucous membrane and lower respiratory sick building syndrome (SBS) symptoms, even at peak dCO{sub 2} concentrations below 1,000 ppm. For this paper, similar analyses were performed using the larger 100-building 1994-1998 BASE dataset. Multivariate logistic regression analyses quantified the associations between dCO{sub 2} and the SBS symptoms, adjusting for age, sex, smoking status, presence of carpet in workspace, thermal exposure, relative humidity, and a marker for entrained automobile exhaust. Adjusted dCO{sub 2} prevalence odds ratios for sore throat and wheeze were 1.17 and 1.20 per 100-ppm increase in dCO{sub 2} (p <0.05), respectively. These new analyses generally support our prior findings. Regional differences in climate, building design, and operation may account for some of the differences observed in analyses of the two datasets.

    With the growing awareness of the presence of non-motor symptoms in Parkinson's disease (PD) has come the realization that these non-motor features play a tremendously important, and sometimes dominant, role in the management and even the diagnosis of the disorder. Despite this, a reluctance to formally address and treat the non-motor symptoms of PD remains and quality of life for PD patients suffers. This review provides an overview of the impact non-motor symptoms have on persons with PD, along with a brief description of some of the more common non-motor features of PD. PMID:26372623

    We present Keck/Echellette Spectrograph and Imager long-slit spectroscopy of SBS 1421+511, a system consisting of a quasar at z = 0.276 and an extended source 3″ north of the quasar. The quasar shows a blue-skewed profile of Balmer broad emission lines, which can be well modeled as emissions from a circular disk with a blueshift velocity of ˜1400 km s-1. The blueshift is better interpreted as resulting from a recoiling active black hole than from a super-massive black hole binary, since the line profile almost kept steady for over one decade in the quasar rest frame. Alternative interpretations are possible as well, such as emissions from a bipolar outflow or a circular disk with spiral emissivity perturbations. The extended source shows Seyfert-like narrow-line ratios and a [O iii] luminosity of \\gt 1.4× {10}8{L}⊙ , with almost the same redshift as the quasar and a projected distance of 12.5 kpc at the redshift. SBS 1421+511 is thus likely to be an interacting galaxy pair with a dual active galactic nucleus. Alternatively, the quasar companion only appears to be active but not necessarily so: the gas before/in/behind the companion galaxy is illuminated by the quasar as an extended emission-line region is detected at a similar distance in the opposite direction southern to the quasar, which may be generated either by tidal interactions between the galaxy pair or large-scale outflows from the quasar.

    2002-01-01

    Patients with physical symptoms for which no medical explanation can be found are relatively common in general practice. Patients with medically unexplained symptoms are frequently frustrating to physicians both in primary and secondary care and utilize health sources disproportionately. They frequently attend both primary care units and hospitals and are usually not satisfied with the care they receive. Medically unexplained symptoms in patient populations are strongly associated with psychiatric pathology and with anxiety and depression in particular. They are also linked to personality pathology, childhood adversity, adult trauma or medically unexplained symptoms in childhood. The predictive value of alexithymia in determining these symptoms is controversial. Patients who have high negative affectivity or neuroticism tend to score high on measures of physical symptoms. These symptoms have a high degree of co-occurrence. The same person may meet the diagnostic criteria for several functional somatic syndromes simultaneously. The clinician should be aware of the cultural and social shaping of the bodily experience of these patients and hence acknowledge the somatic nature and reality of the symptoms. The clinician should make the person feel understood and establish a positive collaborative relationship. This would enable him/her to correct misconceptions about the disease and give a positive explanation of symptoms. Antidepressant therapy and cognitive-behavioural psychotherapy have been proved to be moderately effective in this group of patients. Because of the high disability that might be caused by these symptoms, psychiatrists and primary and secondary care physicians should pay careful attention to this clinical condition. These symptoms may also aid us in challenging the long-held idea of mind-body dualism which is inherent in Western biomedicine. PMID:12794657

    Background. The nonmotor symptoms are important determinants of health and quality of life in Parkinson's disease but are not well recognized and addressed in clinical practice. This study was conducted to determine the prevalence of nonmotor symptoms and their impact on quality of life in patients with Parkinson's disease. Methods. This was a cross-sectional study among patients with idiopathic Parkinson's disease. Exclusion criteria were a Mini Mental State Examination score of <21/30. Prevalence of nonmotor symptoms was determined using the NMSQuest. The severity of nonmotor symptoms and the quality of life were assessed using validated disease-specific questionnaires (PDQ-39 and NMSS). Results. A total of 113 patients consisting of 60 males and 53 females were recruited. The median duration of illness was 5.0 (2.0–8.0) years. The prevalence rate of nonmotor symptoms in our cohort was 97.3%. The most common reported nonmotor symptom in our cohort was gastrointestinal (76.1%). We found that the severity of the nonmotor symptoms was associated with poorer quality of life scores (rs: 0.727, P < 0.001). Conclusions. Nonmotor symptoms were highly prevalent in our patients with Parkinson's disease and adversely affected the quality of life of our patients. In contrast to western studies, the most common nonmotor symptom is gastrointestinal. The possibility of an Asian diet playing a role in this observation requires further study. PMID:24800102

    We wanted to find out, whether the number of depressive symptoms is higher amongst asthmatic children's caregivers, compared to international data, to the Hungarian population average, and to parents of children with chronic renal disease. Are these depressive symptoms connected to the children's psychological status, asthma severity or current asthma symptoms? One-hundred and eight, 7- to 17-yr-old asthmatic children were enrolled, who have been treated at the Semmelweis University, First Department of Pediatrics. Children were suffering from asthma for at least 1 yr, with a median of 8 yr (1-16 yr), they started to develop asthmatic symptoms between the age of 0.5-14 yr (median: 3 yr). We also identified 27 children with chronic renal diseases and their caregivers, who functioned as a control group. Children were asked to complete the Hungarian-validated versions of the Child Depression Inventory, the Spielberger State Anxiety Inventory for Children and the Juniper Pediatric Asthma Quality of Life Questionnaire. Asthma severity and current symptoms were also documented, 56% had no symptoms on the preceding week. Caregivers were asked to complete the Hungarian versions of the Beck Depression Inventory (BDI) short form, the Spielberger Anxiety Inventory and the Juniper Pediatric Asthma Caregivers' Quality of Life Questionnaire. Caregivers of asthmatic children had significantly more depressive symptoms (7.73 +/- 6.69 s.d.) than the age-specific normal population (p < 0.01). Caregivers of renal patients also experience more depressive symptoms (9.61 +/- 7.43 s.d.) than their healthy peers, but difference between the two chronic diseases' group did not prove to be significant. Asthmatic children's caregivers who scored more points on the BDI than the population average suffer from more anxiety symptoms, but their quality of life is not worse than the caregivers' with less depressive points. Depressive symptoms were neither connected to the children's psychological

    Parkinson's disease (PD) is one of the most common forms of neurodegenerative disease in the elderly population and is typically manifested by motor symptoms and nonmotor symptoms and signs. Nonmotor symptoms, such as sensory symptoms, have been regarded as the significant features of this disease. These symptoms often occur in early stages of PD and influence quality of life. However, researchers suggest that the sensory symptoms of PD are frequently unrecognized by clinicians and remain untreated. The disorders include pain, olfactory disturbance, and visual dysfunction input on the underlying sensory abnormality. This Review focuses on the clinical features, pathophysiological mechanisms, and treatment strategies for sensory symptoms of PD from both clinical studies and basic research, providing a comprehensive overview of the sensory symptoms in PD. © 2016 Wiley Periodicals, Inc.

    Summary Patients with advanced life-limiting disease often suffer from symptoms that considerably impair their quality of life and that of their families. Palliative care aims to alleviate these symptoms by a multidimensional approach. Pharmacotherapy is an essential component. The objective of this review is to give an overview of symptom-oriented drug therapy for the most important symptoms in palliative care. Leading symptoms that affect quality of life include pain, dyspnea, nausea and emesis, weakness and disorientation. Careful examination and history taking help to understand the individual mechanisms underlying these symptoms. Specific pharmacotherapy provides an efficient way to achieve symptom control in the context of palliative care. PMID:21547023

    In the last few years, there has been an explosion of new drugs acting on the clinical course of multiple sclerosis (MS) but less attention has been paid to better knowledge of the symptoms of this disease and their pathogenesis and treatment, which is essential to improve patients' quality of life. Because many patients have numerous concurrent symptoms during their clinical course, their management is complex and consequently it is important to know which symptoms are a direct result of the degenerative lesions of MS. The present article describes all the therapeutic options available for spasticity and its associated pain, paroxystic symptoms, fatigue, genitourinary disorders and sexual dysfunction, tremor, ataxia, gait disorder and cognitive impairment, with special emphasis on novel treatments. The article also defines exacerbations, how to recognize them and the available treatments, mainly oral administration of high-dose methylprednisolone and plasmapheresis. PMID:25732949

    PubMed

    Peralta, Cecilia

    2012-01-01

    In the last decade we have witnessed substantial progress towards the understanding of Parkinson's disease. According to pathological and neuroimaging studies, the traditional view of Parkinson's disease that begins with the development of motor symptoms such as bradykinesia, rigidity and tremor, has begun to change. It is now understood that there would be a "premotor" or "preclinical" period in which the alphasynuclein pathology begins outside of the substantia nigra in the lower brainstem and autonomic nervous system. Although the pathophysiology of this phase is still unclear, it is currently thought that its symptoms would correspond to the so-called "non-motor symptoms". Hyposmia, depression, constipation and REM sleep disorders are one of the most relevant non-motor symptoms at this "premotor" stage. The spectrum of non-motor symptoms is very broad and covers the domains of neuropsychiatric, dysautonomic, gastrointestinal and sensory symptoms as well as sleep disorders. Neuropsychiatric symptoms such as depression, impulse control disorder, psychosis and dementia, are a major cause of disability as they are directly related to quality of life. PMID:23979552

  3. Development of new VOC exposure metrics and their relationship to ''Sick Building Syndrome'' symptoms

    SciTech Connect

    Ten Brinke, JoAnn

    1995-08-01

    Volatile organic compounds (VOCs) are suspected to contribute significantly to ''Sick Building Syndrome'' (SBS), a complex of subchronic symptoms that occurs during and in general decreases away from occupancy of the building in question. A new approach takes into account individual VOC potencies, as well as the highly correlated nature of the complex VOC mixtures found indoors. The new VOC metrics are statistically significant predictors of symptom outcomes from the California Healthy Buildings Study data. Multivariate logistic regression analyses were used to test the hypothesis that a summary measure of the VOC mixture, other risk factors, and covariates for each worker will lead to better prediction of symptom outcome. VOC metrics based on animal irritancy measures and principal component analysis had the most influence in the prediction of eye, dermal, and nasal symptoms. After adjustment, a water-based paints and solvents source was found to be associated with dermal and eye irritation. The more typical VOC exposure metrics used in prior analyses were not useful in symptom prediction in the adjusted model (total VOC (TVOC), or sum of individually identified VOCs ({Sigma}VOC{sub i})). Also not useful were three other VOC metrics that took into account potency, but did not adjust for the highly correlated nature of the data set, or the presence of VOCs that were not measured. High TVOC values (2--7 mg m{sup {minus}3}) due to the presence of liquid-process photocopiers observed in several study spaces significantly influenced symptoms. Analyses without the high TVOC values reduced, but did not eliminate the ability of the VOC exposure metric based on irritancy and principal component analysis to explain symptom outcome.

  5. High power, high beam quality regenerative amplifier

    DOEpatents

    Hackel, Lloyd A.; Dane, Clifford B.

    1993-01-01

    A regenerative laser amplifier system generates high peak power and high energy per pulse output beams enabling generation of X-rays used in X-ray lithography for manufacturing integrated circuits. The laser amplifier includes a ring shaped optical path with a limited number of components including a polarizer, a passive 90 degree phase rotator, a plurality of mirrors, a relay telescope, and a gain medium, the components being placed close to the image plane of the relay telescope to reduce diffraction or phase perturbations in order to limit high peak intensity spiking. In the ring, the beam makes two passes through the gain medium for each transit of the optical path to increase the amplifier gain to loss ratio. A beam input into the ring makes two passes around the ring, is diverted into an SBS phase conjugator and proceeds out of the SBS phase conjugator back through the ring in an equal but opposite direction for two passes, further reducing phase perturbations. A master oscillator inputs the beam through an isolation cell (Faraday or Pockels) which transmits the beam into the ring without polarization rotation. The isolation cell rotates polarization only in beams proceeding out of the ring to direct the beams out of the amplifier. The diffraction limited quality of the input beam is preserved in the amplifier so that a high power output beam having nearly the same diffraction limited quality is produced.

    A regenerative laser amplifier system generates high peak power and high energy per pulse output beams enabling generation of X-rays used in X-ray lithography for manufacturing integrated circuits. The laser amplifier includes a ring shaped optical path with a limited number of components including a polarizer, a passive 90 degree phase rotator, a plurality of mirrors, a relay telescope, and a gain medium, the components being placed close to the image plane of the relay telescope to reduce diffraction or phase perturbations in order to limit high peak intensity spiking. In the ring, the beam makes two passes through the gain medium for each transit of the optical path to increase the amplifier gain to loss ratio. A beam input into the ring makes two passes around the ring, is diverted into an SBS phase conjugator and proceeds out of the SBS phase conjugator back through the ring in an equal but opposite direction for two passes, further reducing phase perturbations. A master oscillator inputs the beam through an isolation cell (Faraday or Pockels) which transmits the beam into the ring without polarization rotation. The isolation cell rotates polarization only in beams proceeding out of the ring to direct the beams out of the amplifier. The diffraction limited quality of the input beam is preserved in the amplifier so that a high power output beam having nearly the same diffraction limited quality is produced.

    PTSD symptoms related to school bullying have rarely been investigated, and never in national samples. We used data from a national survey to investigate this among students from grades 8 and 9 (n = 963). The prevalence estimates of exposure to bullying were within the range of earlier research findings. Multinomial logistic regression showed that boys were 2.27 times more likely to be exposed to frequent bullying than girls. A latent variable second-order model demonstrated an association between frequency of bullying exposure and PTSD symptoms (beta = 0.49). This relationship was not moderated by gender. However, the average levels of PTSD symptoms as well as clinical range symptoms were higher for girls. For all bullied students, 27.6% of the boys and 40.5% of the girls had scores within the clinical range. A mimic model showed that youth who identify as being both a bully and a victim of bullying were more troubled than those who were victims only. Our findings support the idea that exposure to bullying is a potential risk factor for PTSD symptoms among students. Future research could investigate whether the same holds for PTSD through diagnostic procedures, but this will depend on whether or not bullying is decided to comply with the DSM-IV classification of trauma required for diagnosis. Results are discussed with regard to their implications for school interventions. PMID:22391775

    Ophthalmologic symptoms are often not sufficiently accounted for by organic pathology. The complaints of these patients have been labeled hysterical, psychogenic, non-organic, or functional. The psychiatric nosology in this area may be the most confusing in the whole field of clinical medicine. The Diagnostic and Statistical Manual of Mental Disorders (DSM-III-R) offers a classification designed to reduce non-empirical concepts and ideology to a minimum. On this background, we discuss the hysterical symptoms encountered in clinical ophthalmology with special emphasis on psychogenic amblyopia and blepharospasm. Motor symptoms are commonly not of psychogenic origin. It is suggested that ophthalmologists are most likely to treat patients with psychogenic symptoms, using suggestion, patience, and reassurance. Few patients require psychiatric consultation and a specific psychiatric therapy. The association of hysteria with organic brain disease and the issue of symptom lateralization are briefly discussed. Eventually, we reject the psychoanalytic approach and suggest that the concept of abnormal illness behavior and the neurobiological models involving corticofugal inhibition, primitive reflex mechanisms, and an attention disturbance, serve best to understand the nature of the phenomenon hysteria.

    We examined the effects of maternal history of depressive disorder and the effects of depressive symptoms during pregnancy and the early postpartum period on attachment insecurity and disorganization. A total of 627 mother-infant dyads from the Generation R Study participated in a population-based cohort from fetal life onwards. Maternal history of depression was assessed by diagnostic interviews during pregnancy; maternal peri- and postnatal depressive symptoms were assessed with questionnaires in 506 of these women at 20 weeks pregnancy and two months postpartum; and infant-mother attachment security was observed when infants were aged 14 months. A history of maternal depressive disorder, regardless of severity or psychiatric comorbidity, was not associated with an increased risk of infant attachment insecurity or disorganization. Likewise, maternal peri- and postnatal depressive symptoms were not related to attachment insecurity or disorganization at 14 months. These results are important because mothers from otherwise low risk backgrounds often have previously been depressed or are struggling with non-clinical depressive symptoms during pregnancy and after giving birth. Our findings are discussed in terms of protective factors that may limit the potentially negative effects of maternal depressive symptoms on the infant-mother attachment relationship in the general population. The role of selective attrition and lack of information about the mothers' attachment status for the current null-findings are also discussed. PMID:22191607

  10. Symptoms of depression in ICU physicians

    2012-01-01

    Background Work and family are the two domains from which most adults develop satisfaction in life. They also are responsible for stressful experiences. There is a perception in the community that work is increasingly the source of much of our stress and distress. Depressive symptoms may be related to repeated stressful experiences. Intensive care unit (ICU) physicians are exposed to major stressors. However, the existence of depressive symptoms in these doctors has been poorly studied. This study was designed to evaluate the prevalence and associated risk factors of depressive symptoms in junior and senior ICU physicians. Method A one-day national survey was conducted in adult intensive care units (ICU) in French public hospitals. Symptoms of depression were assessed using the Centers of Epidemiologic Studies Depression Scale (CES-D). Results A total of 189 ICUs participated, and 901 surveys were returned (75.8% response rate). Symptoms of depression were found in 23.8% of the respondents using the CES-D scale. Fifty-eight percent of these intensivists presenting symptoms of depression wished to leave their job compared with only 33% of those who did not exhibit signs of depression as assessed by the CES-D scale (p < 0.0001). Multiple logistic regression showed that organizational factors were associated with the presence of depressive symptoms. Workload (long interval since the last nonworking weekend, absence of relief of service until the next working day after a night shift) and impaired relationships with other intensivists were independently associated with the presence of depressive symptoms. A high level of burnout also was related to the presence of depressive symptoms. In contrast, no demographic factors regarding ICU physicians and no factor related to the severity of illness of patients were retained by the model. The quality of relationships with other physicians (from other departments) was associated with the absence of depressive symptoms

    Background Major depression is common in coronary heart disease (CHD) but challenging to diagnose. Instead of focusing on the overall diagnosis of depression, base rates of depressive symptoms could facilitate screening and management of psychopathology in CHD. The present study investigates the frequency of individual depressive symptoms in CHD and their impact on cardiac and subjective health. Methods In total, 1337 in- and outpatients with CHD were screened for depressive symptoms with the Patient Health Questionnaire-9 (PHQ-9) at three different cardiac treatment sites. Tables stratified by age and gender were designed to illustrate base rates of depressive symptoms. Multiple regression analyses adjusted for sociodemographic and clinical data were conducted to test associations between individual depressive symptoms and quality of life as well impairment caused angina pectoris and dyspnea. Results During the last 14 days, more than half of patients reported a loss of energy (74.9%, 95% Confidence Interval (CI): 70.6–79.2), sleeping problems (69.4%, 95% CI: 64.9–74.0), loss of interest (55.7%, 95% CI: 50.8–60.7). In contrast, psychomotor change (25.6%, 95%CI: 21.3–30.0), feelings of failure (21.9%, 95%CI: 17.7–26.0), suicidal ideations (14.1%, 95%CI: 10.7–17.6) were less frequently reported. Depending on the outcome, only particular depressive symptoms were highly associated with low quality of life and impairment caused by angina pectoris and dyspnea. Loss of energy was the only depressive symptom that reliably predicted all three outcomes. Conclusions Depressive symptoms in CHD are frequent but vary widely in terms of frequency. Findings underline the differential effects of individual depressive symptoms on cardiac health. Presented base rates of depressive symptoms offer clinicians a new way to judge the severity of individual depressive symptoms and to communicate individual PHQ-9 profiles with patients with respect to gender, age, cardiac

    Background Respiratory symptoms are commonly used to assess the impact of patient-centered interventions. Objective At the request of National Institutes of Health (NIH) institutes and other federal agencies, an expert group was convened to propose which measurements of asthma symptoms should be used as a standardized measure in future clinical research studies. Methods Asthma symptom instruments were classified as daily diaries (prospectively recording symptoms between research visits) or retrospective questionnaires (completed at research visits). We conducted a systematic search in PubMed and a search for articles that cited key studies describing development of instruments. We classified outcome instruments as either core (required in future studies), supplemental (used according to study aims and standardized), or emerging (requiring validation and standardization). This work was discussed at an NIH-organized workshop in March 2010 and finalized in September 2011. Results Four instruments (3 daily diaries, 1 for adults and 2 for children; and 1 retrospective questionnaire for adults) were identified. Minimal clinically important differences have not been established for these instruments, and validation studies were only conducted in a limited number of patient populations. Validity of existing instruments may not be generalizable across racial-ethnic or other subgroups. Conclusions An evaluation of symptoms should be a core asthma outcome measure in clinical research. However, available instruments have limitations that preclude selection of a core instrument. The working group participants propose validation studies in diverse populations, comparisons of diaries versus retrospective questionnaires, and evaluations of symptom assessment alone versus composite scores of asthma control.

    Surface layer (S-layer) proteins self-assemble into two-dimensional crystalline lattices that cover the cell wall of all archaea and many bacteria. We have generated assembly-negative protein variants of high solubility that will facilitate high-resolution structure determination. Assembly-negative versions of the S-layer protein SbsB from Geobacillus stearothermophilus PV72/p2 were obtained using an insertion mutagenesis screen. The haemagglutinin epitope tag was inserted at 23 amino acid positions known to be located on the monomer protein surface from a previous cysteine accessibility screen. Limited proteolysis, circular dichroism, and fluorescence were used to probe whether the epitope insertion affected the secondary and tertiary structures of the monomer, while electron microscopy and size-exclusion chromatography were employed to examine proteins' ability to self-assemble. The screen not only identified assembly-compromised mutants with native fold but also yielded correctly folded, self-assembling mutants suitable for displaying epitopes for biomedical and biophysical applications, as well as cryo-electron microscopy imaging. Our study marks an important step in the analysis of the S-layer structure. In addition, the approach of concerted insertion and cysteine mutagenesis can likely be applied for other supramolecular assemblies. PMID:19836402

    A numerical investigation is reported of the influence of the thermal self-interaction of a Gaussian pump beam on the quality of phase conjugation by stimulated Brillouin scattering (SBS). A laser pulse is assumed to be sufficiently long to apply the equalised pressure approximation in calculating the acoustic field. All the calculations are carried out in a three-dimensional formulation for focused beams making use of an approximation linear in respect of the pump intensity. It is confirmed that the growth of thermal perturbations increases the SBS threshold and lowers the phase conjugation quality. A comparison of the calculated and published experimental results shows that they are in satisfactory quantitative agreement. (nonlinear optical phenomena and devices)

    Patients with CHD are vulnerable to psychiatric disorders. The present study compared baseline depressive symptoms between adolescents with CHD and community adolescents, and also assessed the development and persistence of depressive symptoms in patients. We examined the implications of persistent depressive symptoms towards quality of life and patient-reported health. In total, 296 adolescents with CHD participated in a four-wave longitudinal study, with 9-month intervals, and completed measures of depressive symptoms - Center for Epidemiologic Studies Depression Scale (CES-D) - at time points one to four and of quality of life - linear analogue scale (LAS) - and patient-reported health - LAS and Pediatric Quality of Life Inventory - at T (time) 4. Information about diagnosis, disease complexity, and previous heart surgery was collected from medical records. At T1, 278 patients were matched 1:1 with community adolescents, based on sex and age. The findings of this study indicate that patients scored significantly lower on depressive symptoms compared with community adolescents. Depressive symptoms in the total patient sample were stable over time and were unrelated to disease complexity. Based on conventional cut-off scores of the CES-D, substantial individual differences existed in the extent to which depressive symptoms persisted over time: 12.2% of the patients reported elevated depressive symptoms at minimally three out of the four time points. Especially physical functioning, cardiac symptoms, and patient-reported health at T4 were predicted by persistent depressive symptoms, even when controlling for the level of depressive symptoms at T4. Our findings indicate that those involved in the care of adolescents with CHD should remain vigilant to persistent depressive symptoms and arrange timely referral to mental healthcare services.

    OBJECTIVE: To develop a new specific instrument called the Autonomic Symptom Profile to measure autonomic symptoms and test its validity. BACKGROUND: Measuring symptoms is important in the evaluation of quality of life outcomes. There is no validated, self-completed questionnaire on the symptoms of patients with autonomic disorders. METHODS: The questionnaire is 169 items concerning different aspects of autonomic symptoms. The Composite Autonomic Symptom Scale (COMPASS) with item-weighting was established; higher scores indicate more or worse symptoms. Autonomic function tests were performed to generate the Composite Autonomic Scoring Scale (CASS) and to quantify autonomic deficits. We compared the results of the COMPASS with the CASS derived from the Autonomic Reflex Screen to evaluate validity. RESULTS: The instrument was tested in 41 healthy controls (mean age 46.6 years), 33 patients with nonautonomic peripheral neuropathies (mean age 59.5 years), and 39 patients with autonomic failure (mean age 61.1 years). COMPASS scores correlated well with the CASS, demonstrating an acceptable level of content and criterion validity. The mean (+/-SD) overall COMPASS score was 9.8 (+/-9) in controls, 25.9 (+/-17.9) in the patients with nonautonomic peripheral neuropathies, and 52.3 (+/-24.2) in the autonomic failure group. Scores of symptoms of orthostatic intolerance and secretomotor dysfunction best predicted the CASS on multiple stepwise regression analysis. CONCLUSIONS: We describe a questionnaire that measures autonomic symptoms and present evidence for its validity. The instrument shows promise in assessing autonomic symptoms in clinical trials and epidemiologic studies.

    Background In addition to their respiratory symptoms, patients with COPD experience multiple, co-occurring symptoms. Objectives The aims of this study were to identify subgroups of COPD patients based on their distinct experiences with 14 symptoms and to determine how these subgroups differed in demographic and clinical characteristics and disease-specific quality of life. Patients and methods Patients with moderate, severe, and very severe COPD (n=267) completed a number of self-report questionnaires. Latent class analysis was used to identify subgroups of patients with distinct symptom experiences based on the occurrence of self-reported symptoms using the Memorial Symptom Assessment Scale. Results Based on the probability of occurrence of a number of physical and psychological symptoms, three subgroups of patients (ie, latent classes) were identified and named “high”, “intermediate”, and “low”. Across the three latent classes, the pairwise comparisons for the classification of airflow limitation in COPD were not significantly different, which suggests that measurements of respiratory function are not associated with COPD patients’ symptom burden and their specific needs for symptom management. While patients in both the “high” and “intermediate” classes had high occurrence rates for respiratory symptoms, patients in the “high” class had the highest occurrence rates for psychological symptoms. Compared with the “intermediate” class, patients in the “high” class were younger, more likely to be women, had significantly more acute exacerbations in the past year, and reported significantly worse disease-specific quality of life scores. Conclusion These findings suggest that subgroups of COPD patients with distinct symptom experiences can be identified. Patients with a higher symptom burden warrant more detailed assessments and may have therapeutic needs that would not be identified using current classifications based only on

    Approximately 40,000 women die as a result of breast cancer each year and many more live with advanced disease. When breast cancer recurs, the goals of treatment often shift from one of cure to controlling the disease for as long as possible while palliating symptoms interfering with the patient's functional status and quality of life. This requires ongoing discussions with the patient and family about the goals of care. Many symptoms depend on the site of metastasis, with bone being the most frequent, and commonly occur with fatigue, depression, insomnia, and pain. The purpose of this paper is to identify and provide an overview of the management of the most common symptoms in patients with breast cancer metastases. PMID:21880861

    Summary Introduction: Practical and portable the personal stereos if had become almost indispensable accessories in the day the day. Studies disclose that the portable players of music can cause auditory damages in the long run for who hear music in high volume for a drawn out time. Objective: to verify the prevalence of auditory symptoms in users of amplified players and to know its habits of use Method: Observational prospective study of transversal cut carried through in three institutions of education of the city of Salvador BA, being two of public net and one of the private net. 400 students had answered to the questionnaire, of both the sex, between 14 and 30 years that had related the habit to use personal stereos. Results: The symptoms most prevalent had been hyperacusis (43.5%), auricular fullness (30.5%) and humming (27.5), being that the humming is the symptom most present in the population youngest. How much to the daily habits: 62.3% frequent use, 57% in raised intensities, 34% in drawn out periods. An inverse relation between exposition time was verified and the band of age (p = 0,000) and direct with the prevalence of the humming. Conclusion: Although to admit to have knowledge on the damages that the exposition the sound of high intensity can cause the hearing, the daily habits of the young evidence the inadequate use of the portable stereos characterized by long periods of exposition, raised intensities, frequent use and preference for the insertion phones. The high prevalence of symptoms after the use suggests a bigger risk for the hearing of these young. PMID:25991931

    The neuropsychiatric symptoms of dementia can lead to a decreased quality of life, rapid cognitive decline, early patient institutionalization, tremendous caregiver burden, and increased cost of care. A thorough assessment to evaluate and treat any underlying causes of symptoms is essential. With the lack of an approved drug to treat the neuropsychiatric symptoms of dementia, nonpharmacologic interventions take on added importance. Behavioral management, cognitive stimulation therapy, and caregiver and health care staff education have shown the most promise to reduce symptom burden over the long term. The antipsychotic drugs have been the traditional choice of medications to treat the neuropsychiatric symptoms of dementia, but safety problems emerged with their use, leading to the issuance of label changes ("black box" warnings) by the Food and Drug Administration. Aside from antipsychotic drugs, multiple classes of medications have been tried to treat such symptoms but long-term data showing efficacy and safety are often lacking. PMID:19400596

    We present near-infrared (NIR) spectroscopic observations of five blue compact dwarf (BCD) galaxies, II Zw 40, Mrk 71, Mrk 930, Mrk 996, and SBS 0335-052E. The NIR spectra which cover the 0.90-2.40 {mu}m wavelength range show hydrogen, molecular hydrogen, helium, sulfur, and iron emission lines. The NIR data for all BCDs have been supplemented by optical spectra. We found the extinction coefficient in all BCDs to be very similar in both the optical and NIR ranges. The NIR hydrogen emission lines do not reveal more star formation than seen in the optical. The same conclusion is reached from Spitzer data concerning the mid-infrared (MIR) emission lines. This implies that emission line spectra of low-metallicity BCDs in the {approx}0.36-25 {mu}m wavelength range are emitted by relatively transparent ionized gas. The large extinction derived from the MIR continuum emission in some BCDs implies that the latter arises not from the visible H II regions themselves, but from locations outside these H II regions. The H{sub 2} emission line fluxes can be accounted for by fluorescence. CLOUDY stellar photoinization models of all BCDs reproduce well the fluxes of most of the observed optical and NIR emission lines, except in Mrk 930 where shock ionization is needed to account for the [Fe II] emission lines. However, some contribution of shock ionization at the level of {approx}<10% that of stellar ionization is required to reproduce the observed fluxes of high ionization species, such as He II {lambda}0.469 {mu}m in the optical range and [O IV] {lambda}25.89 {mu}m in the MIR range.

    Chronic obstructive pulmonary disease (COPD) has traditionally been considered an inexorably progressive disease, associated with a constant increase of symptoms that occur as the forced expiratory volume in 1 second (FEV1) worsens, only intermittently interrupted by exacerbations. However, this paradigm has been challenged in recent decades by the available evidence. Recent studies have pointed out that COPD-related symptoms are not consistently perceived by patients in the same way, showing not only seasonal variation, but also changes in symptom perception during a week or even within a single day. According to the available data, patients experience the biggest increase in respiratory symptoms during the first hours of the early morning, followed by the nighttime. This variation over time is of considerable importance, since it impacts on daily life activities and health-related quality of life, as measured by a recently developed ad hoc questionnaire. Additionally, recent clinical trials have suggested that the use of rapid-onset long-acting bronchodilators may have an impact on morning symptoms, despite their current use as maintenance treatment for a determined period. Although this hypothesis is to be validated in future long-term clinical trials comparing fast-onset versus slow-onset inhaled drugs in COPD, it may bring forward a new concept of long-term bronchodilator therapy. At the present time, the two available long-acting, fast-onset bronchodilators used in the treatment of COPD are formoterol and the recently marketed indacaterol. Newer drugs have also been shown to have a rapid onset of action in preclinical studies. Health care professionals caring for COPD patients should consider this variation in the perception of symptoms during their clinical interview as a potential new target in the long-term treatment plan.

    Adverse reactions to foods can be due to many causes, but only those involving an immunological mechanism can be defined as food allergic disease. An increasing number of gastrointestinal and other diseases are being shown to involve food intolerances. Immediate reactions with symptoms within hours of eating a particular food are most readily shown to be due to food allergy and are often associated with the presence of food-specific IgE as shown by skin prick tests and RASTs. When reactions are delayed for 24 to 48 hours or more, underlying food intolerance is harder to recognize and much less often shown to be due to allergy. At present, diagnosis and management depends on dietary manipulation, showing that symptoms improve on food avoidance and are reproduced by food challenge (preferably double-blind). Further understanding of the mechanisms involved in food allergy, in Crohn's disease and irritable bowel syndrome may allow the development of simple tests to identify the foods concerned and perhaps, in the case of allergic disease, cure by the induction of tolerance.

    Hypophosphatasia (HPP) is a bone metabolic disorder caused by mutations in the liver/bone/kidney alkaline phosphatase gene (ALPL), which encodes tissue-nonspecific alkaline phosphatase (TNAP). This disease is characterized by disrupted bone and tooth mineralization, and reduced serum AP activity. Along with bone and tooth symptoms, many neurological symptoms, seizure, encephalopathy, intracranial hypertension, mental retardation, deafness, and growth hormone deficiency (GHD), are frequently found in HPP patients. Seizure occurs in severe HPP types soon after birth, and responds to pyridoxine, but is an indicator of lethal prognosis. Encephalopathy rarely presents in severe HPP types, but has severe sequelae. Intracranial hypertension complicated in mild HPP types develops after the age of 1 year and sometimes need neurosurgical intervention. Mental retardation, deafness and GHD are more frequently found in Japanese HPP patients. Mental retardation occurs in all HPP types. Deafness in perinatal lethal type is both conductive and sensorineural. GHD develops in all but perinatal lethal type and the diagnosis tends to delay. The pathogenesis of these neural features of HPP might be due to impairment of both vitamin B6 metabolism and central nervous system development by ALPL mutations. PMID:26219717

    In summary, caring for patients with MUS is challenging for health care providers. Even defining somatization syndromes is complex and controversial, reflecting the medical community’s limited understanding of the pathophysiology for this group of disorders. Although risk factors for MUS have been described and are well understood, little is known about how MUS can be prevented. Uncertainty in medicine, as in any human enterprise, is a given, but the difficulties in identification and treatment of patients with MUS highlight the limitations in understanding the intersection between physical and mental health. Patients come to their physician looking for clarity, understanding, and relief of debilitating symptoms. The understanding of MUS will evolve, and perhaps an organic cause not yet understood or described may emerge to lend clarity and therapeutic opportunities to some patients with somatic disorders. In the meantime, the most powerful tools available are the ability to communicate the limits of current understanding, acknowledge the difficulties faced by patients with this disorder, and reinforce the willingness and desire of clinicians to partner with patients as the focus shifts from diagnosis to symptom management. Thus, the physician-patient relationship, still in its rightful place at the heart of the practice of medicine, lies at the center of effective treatment of patients with MUS. PMID:24758967

    Background A number of instruments have been developed to measure health-related quality-of-life (HRQoL), differing in the health domains covered and their scoring. While few such measures have been consistently included in U.S. national health surveys over time, the surveys have included data on a broad range of symptoms and impairments, which enables the tracking of population health trends. Objectives To compare trends in HRQoL as measured using existing instruments vs. using a broader range of symptoms and impairments collected in multiple years of nationally representative data. Data and Measures Data were from the 2000 to 2010 Medical Expenditure Panel Survey (MEPS), which is nationally representative of the non-institutionalized U.S. population. Level of and trends in HRQoL derived from a broad range of survey symptoms and impairments (SSI) was compared to HRQoL from the SF-6D, the HALex, and, between 2000 and 2003, the EuroQol-5D (EQ-5D) and EQ-5D Visual Analog Scale. Results Trends in HRQoL were similar using different measures. The SSI scores correlated 0.66 to 0.80 with scores from other measures and mean SSI scores were between those of other measures. Scores from all HRQoL measures declined similarly with increasing age and with the presence of comorbid conditions. Conclusion Measuring HRQoL using a broader range of symptoms and impairments than those in a single instrument yields population health trends similar to those from other measures while making maximum use of existing data and providing rich detail on the factors underlying change.

  16. Symptoms of transient ischemic attack.

    PubMed

    Kim, Jong S

    2014-01-01

    Transient ischemic attack (TIA) is a cerebrovascular disease with temporary (<24 h) neurological symptoms. The symptoms of TIA patients are largely similar to those of ischemic stroke patients and include unilateral limb weakness, speech disturbances, sensory symptoms, visual disturbances, and gait difficulties. As these symptoms are transient, they are frequently evaluated based on patients' subjective reports, which are less precise than those of patients with stroke whose longer-lasting symptoms and signs can be reliably assessed by physicians. Some symptoms, such as monocular blindness, are much more common in TIA than in stroke, and limb shaking occurs almost exclusively in TIA patients. On the other hand, symptoms like hemivisual field defects or limb ataxia are underappreciated in TIA patients. These transient neurological symptoms are not necessarily caused by cerebrovascular diseases, but can be produced by a variety of non-vascular diseases. Careful history taking, examination, and appropriate imaging tests are needed to differentiate these TIA mimics from TIA. Each TIA symptom has a different specificity and sensitivity, and there has been an effort to assess the outcome of the patients through the use of specific clinical features. On top of this, recent developments in imaging techniques have greatly enhanced our ability to predict the outcomes of TIA patients. Perception or recognition of TIA symptoms may differ according to the race, sex, education, and specialty of physicians. Appropriate education of both the general population and physicians with regard to TIA symptoms is important as TIAs need emergent evaluation and treatment. PMID:24157558

    Two new quaternary sulfides La2Ga0.33SbS5 and Ce4GaSbS9 have been prepared from stoichiometric elements at 1223 K in an evacuated silica tube. Interestingly, La2Ga0.33SbS5 crystallizes in the centrosymmetric structure, while Ce4GaSbS9 crystallizes in the noncentrosymmetric structure, which show obvious size effects of lanthanides on the crystal structures of these two compounds. Ce4GaSbS9 belongs to RE4GaSbS9 (RE=Pr, Nd, Sm, Gd-Ho) structure type with a=13.8834(9) Å, b=14.3004(11) Å, c=14.4102(13) Å, V=2861.0(4) Å3. The structure features infinite chains of [Ga2Sb2S1110-]∞ propagating along a direction separated by Ce3+ cations and S2- anions. La2Ga0.33SbS5 adopts the family of La4FeSb2S10-related structure with a=7.5193(6) Å, c=13.4126(17) Å, V=758.35(13) Å3. Its structure is built up from the alternate stacking of La/Sb/S and La/Ga/S 2D building blocks. The La/Sb/S slabs consist of teeter-totter chains of Sb1S4 seesaws, which are connected via sharing the apexes of μ4-S1. Moreover, La1 is positionally disordered with Sb1 and stabilized in a bicapped trigonal prismatic coordination sphere. Between these La/Sb/S slabs, La2S8 square antiprisms are connected via edge-sharing into 2D building blocks, creating tetrahedral sites partially occupied by the Ga1 atoms. UV/Vis diffuse reflectance spectroscopy study shows that the optical gap of La2Ga0.33SbS5 is about 1.76 eV.

    Testes descend to the scrotum normally before birth. When they fail to do so, the boy is cryptorchid and has an increased risk for testicular germ cell cancer and subfertility later in life. Early correction of maldescent by orchiopexy operation improves the spermatogenetic capacity of the testis but does not return the testicular cancer risk to the control level. Testicular descent is regulated by testis-derived hormones testosterone and insulin-like peptide 3. Cryptorchidism can therefore be considered a symptom of impaired testicular function that may also be linked to other testicular diseases, such as germ cell cancer and subfertility. Early orchiopexy can alleviate the effects of cryptorchidism on spermatogenesis, but alertness for testicular cancer should be maintained. In searching the genetic and environmental reasons for these diseases, it is useful to consider their connection with each other. PMID:24786701

  20. Improving Symptom Control in Early Parkinson's Disease

    PubMed Central

    Hauser, Robert A.

    2009-01-01

    Motor symptoms in Parkinson's disease (PD) are caused by a severe loss of pigmented dopamine-producing nigro-striatal neurons. Symptomatic therapies provide benefit for motor features by restoring dopamine receptor stimulation. Studies have demonstrated that delaying the introduction of dopaminergic medical therapy is associated with a rapid decline in quality of life. Nonmotor symptoms, such as depression, are common in early PD and also affect quality of life. Therefore, dopaminergic therapy should typically be initiated at, or shortly following, diagnosis. Monamine oxidase-B inhibitors provide mild symptomatic benefit, have excellent side effect profiles, and may improve long-term outcomes, making them an important first-line treatment option. Dopamine agonists (DAs) provide moderate symptomatic benefit but are associated with more side effects than levodopa. However, they delay the development of motor complications by delaying the need for levodopa. Levodopa (LD) is the most efficacious medication, but its chronic use is associated with the development of motor complications that can be difficult to resolve. Younger patients are more likely to develop levodopa-induced motor complications and they are therefore often treated with a DA before levodopa is added. For older patients, levodopa provides good motor benefit with a relatively low-risk of motor complications. Using levodopa with a dopa-decarboxylase inhibitor lessens adverse effects, and further adding a catechol-O-methyl transferase inhibitor can improve symptom control. PMID:21180628

    2011-02-01

    In this paper, we present results on a master-oscillator Yb-doped fiber amplifier with 1 kW cw output power (at 1064nm), and near-diffraction limited beam quality (M2<1.4), with internal quantum efficiency >83%. The final amplifier stage uses a very high Yb-doped 35-um core LMA fiber, using a new process recipe that virtually eliminates photo-darkening. As a result, high efficiency, SBS-free operation to 1 kW cw power level is obtained, with a phase modulation bandwidth of only 450MHz, well below other reported results. To enable single-frequency cw power scaling to kW levels, we investigate LMA fiber waveguide designs exploiting gain-discrimination, using partially Yb-doped LMA fiber cores, with various diameters up to 80-um. SBS-free, singlefrequency (few kHz) operation is demonstrated up to 0.9kW cw power. At the lower cw powers (<200W) neardiffraction limited beam-quality is obtained, but is observed to deteriorate at higher cw powers. We discuss potential causes, and present a detailed simulation model of kW large-core fiber-amplifiers, that includes all guided modes, fiber bend, transverse spatial hole burning, gain-tailoring, mode-scattering, SBS nonlinearity, and various thermal effects. This model shows good agreement with the observed single-frequency power scaling and beam-quality characteristics.

    Neurological symptoms are very common in children with life-limiting conditions and are challenging in terms of burden of illness. Moreover, neurological symptoms can significantly impact the child’s quality of life and contribute to distress among parents, families, caregivers and health care providers. Knowing how to manage and alleviated these symptoms is essential for providing good palliative care. In the present article, the more common neurological symptoms of agitation/irritability, spasticity and dystonia will be reviewed. The aim of the present brief review is to provide a basic approach to both the identification and treatment of these neurological symptoms. A medication table is provided for quick reference. A brief commentary and guidance for the management of pain are also incorporated, with reference to further literature sources. PMID:25914579

    The physical and affective symptoms of a broad range of conditions are improved following mindfulness-based practices. One set of symptoms that has yet to be explored through the lens of mindfulness, however, is that associated with the premenstruum. Also, given the relationships among negative attitudes towards menstruation and amplified symptom reporting, it is reasonable to expect that mindfulness qualities cultivated through practices aimed at dispelling negative anticipatory and judgmental thinking will moderate these relationships. Thus, in this study we examined interrelationships among premenstrual symptom severity reports (PMSR), menstrual attitudes, and mindfulness qualities in a sample of 127 women (age range 18–26 years). Results revealed several statistically significant positive relationships between menstrual attitudes and PMSR. Also, higher scores on measures of mindfulness were significantly associated with lower PMSR. Moderating effects revealed that mindfulness significantly buffered the relationships between menstrual attitudes and PMSR, specifically between: anticipation of menses onset and PMSR as well as anticipation of menses onset and premenstrual water retention. These results may offer the first empirical evidence of relationships among menstrual attitudes, PMSR, and mindfulness qualities. Results from this study align with the body of research showing that mindfulness is predictive of improved symptomatology and well-being across varied conditions. We conclude with discussion supporting the development of a mindfulness-based intervention aimed at reducing symptom severity in premenstrual symptom sufferers. PMID:27162560

    This study was undertaken to determine which symptoms are perceived to be most problematic for patients with ALS and how their severity changes over time. A retrospective study was performed of data from a randomized, double-blind, placebo-controlled trial of ceftriaxone in ALS. Participants completed the ALS Specific Quality of Life Instrument (ALSSQoL) at baseline and at intervals up to 96 weeks. Ten ALSSQoL items ask participants to rate how problematic symptoms are (the subjective feeling of burden of these symptoms), ranging from 0 (no problem) to 10 (tremendous problem). Six are non-bulbar (pain, fatigue, breathing, strength and ability to move, sleep, and bowel and bladder) and four are bulbar (eating, speaking, excessive saliva, and mucus). Results revealed that there were 82 subjects (56% males, mean age 53 ± 10.3 years) with ALSSQoL data for weeks 0 and 96. All 10 symptoms became more problematic over time. For non-bulbar symptoms, strength/ability to move and fatigue were the most problematic. Speaking was the most problematic bulbar symptom. In conclusion, although all the symptoms in the ALSSQoL were acknowledged as problematic, some had greater impact than others. All became more problematic over time. This should help prioritize research into symptom management, and assist individual clinicians in their approach to patient care. PMID:26824413

    Background Depression is a well-recognised problem in the elderly. The aim of this study was to determine the factors associated with predictors of change in depressive symptoms, both in subjects with and without baseline significant depressive symptoms. Methods Longitudinal study of community-dwelling elderly people (>60 years or older), baseline evaluations, and two additional evaluations were reported. Depressive symptoms were measured using a 30-item Geriatric Depression Scale, and a score of 11 was used as cutoff point for significant depressive symptoms in order to stratify the analyses in two groups: with significant depressive symptoms and without significant depressive symptoms. Sociodemographic data, social support, anxiety, cognition, positive affect, control locus, activities of daily living, recent traumatic life events, physical activity, comorbidities, and quality of life were evaluated. Multi-level generalised estimating equation model was used to assess the impact on the trajectory of depressive symptoms. Results 7,882 subjects were assessed, with 29.42% attrition. At baseline assessment, mean age was 70.96 years, 61.15% were women. Trajectories of depressive symptoms had a decreasing trend. Stronger associations in those with significant depressive symptoms, were social support (OR .971, p<.001), chronic pain (OR 2.277, p<.001) and higher locus of control (OR .581, p<.001). In contrast for those without baseline significant depressive symptoms anxiety and a higher locus of control were the strongest associations. Conclusions New insights into late-life depression are provided, with special emphasis in differentiated factors influencing the trajectory when stratifying regarding basal status of significant depressive symptoms. Limitations The study has not included clinical evaluations and nutritional assessments PMID:23731940

    Aim: The study was conducted at Artificial Breeding Research Centre, NDRI, Karnal, to determine the sexual behavior and its relationship with semen quality parameters in Sahiwal breeding bulls. Materials and Methods: A total of 63 ejaculates were collected from six adult Sahiwal bulls (age ~47 mo and bwt ~466 kg), to study the relationship of sexual behavior and semen quality. The degree of association between different variables was estimated by Pearson’s correlation coefficient method. Results: The results depicted that, sexual aggressiveness showed significantly high positive correlation with libido score (LS) and sexual behavior score (SBS). Reaction time (RT) and total time taken in mounts (TTTM) had a significant negative correlation with LS and SBS. Penile erection score and penile protrusion score (PPS) both had a significant positive correlation with ejaculatory thrust score, mating ability score, and SBS. Results of correlation among seminal attributes and with sexual behavior depicted that ejaculate volume had positive significant correlation with initial progressive motility (IPM), sperm concentration (SCON), head abnormality, total abnormality, hypo-osmotic swelling test (HOST), acrosomal integrity (AI) whereas, mass activity had positive significant correlation with IPM, SCON, non-eosinophilic spermatozoa count (NESC), HOST, AI, RT and TTTM and IPM had positive significant correlation with SCON, NESC, HOST, AI, and TTTM, whereas and HOST had positive significant correlation with AI. Among seminal attributes, SCON had a positive significant correlation with PPS where as head abnormalities had a positive significant correlation with RT and TTTM. Conclusion: It can be concluded that the relationship of sexual behavior and semen quality parameters are reflecting that the sexual behavior of individual bulls is important to harvest good quality and quantity of semen as desired type of sexual preparation can be provided.

    Although atrial fibrillation (AF) symptom severity is used to guide clinical care, a simple, standardized assessment tool is not available for routine clinical use. We sought to develop and validate a patient-generated score and classification scheme for AF-related symptom severity and burden. Atrial Fibrillation Symptom and Burden, a simple 2-part questionnaire, was designed to assess (1) AF symptom severity using 8 questions to determine how symptoms affect daily life and (2) AF burden using 6 questions to measure AF frequency, duration, and health-care utilization. The resulting score was used to classify patients into 4 classes of symptom and burden severity. Patients were asked to complete the questionnaire, a survey evaluating the questionnaire, and an Short Form-12v2 generic health-related quality-of-life form. Validation of the questionnaire included assessments of its reliability and construct and known groups validity. The strength of interrater agreement between patient-generated and blinded provider-generated classifications of AF symptom severity was also assessed. The survey had good internal consistency (Cronbach α>0.82) and reproducibility (intraclass correlation coefficient=0.93). There was a good linear correlation with health-related quality-of-life aggregates measured by Pearson correlation coefficient (r=0.62 and 0.42 vs physical component summary and mental component summary, respectively). Compared with physical and mental component summary scores, the patient-generated symptom severity classification scheme showed robust discrimination between mild and moderate severity (p<0.0001 and p=0.0009) and between moderate and severe groups (p=0.0001 and p=0.012). In conclusion, this simple patient-generated AF classification scheme is robust, internally consistent, reproducible, and highly correlated with standardized quality-of-life measures. PMID:24878121

    Studies investigating neurobiological bases of negative symptoms of schizophrenia failed to provide consistent findings, possibly due to the heterogeneity of this psychopathological construct. We tried to review the findings published to date investigating neurobiological abnormalities after reducing the heterogeneity of the negative symptoms construct. The literature in electronic databases as well as citations and major articles are reviewed with respect to the phenomenology, pathology, genetics and neurobiology of schizophrenia. We searched PubMed with the keywords "negative symptoms," "deficit schizophrenia," "persistent negative symptoms," "neurotransmissions," "neuroimaging" and "genetic." Additional articles were identified by manually checking the reference lists of the relevant publications. Publications in English were considered, and unpublished studies, conference abstracts and poster presentations were not included. Structural and functional imaging studies addressed the issue of neurobiological background of negative symptoms from several perspectives (considering them as a unitary construct, focusing on primary and/or persistent negative symptoms and, more recently, clustering them into factors), but produced discrepant findings. The examined studies provided evidence suggesting that even primary and persistent negative symptoms include different psychopathological constructs, probably reflecting the dysfunction of different neurobiological substrates. Furthermore, they suggest that complex alterations in multiple neurotransmitter systems and genetic variants might influence the expression of negative symptoms in schizophrenia. On the whole, the reviewed findings, representing the distillation of a large body of disparate data, suggest that further deconstruction of negative symptomatology into more elementary components is needed to gain insight into underlying neurobiological mechanisms.

    Despite the official exclusion criteria for autism spectrum disorder (ASD) and attention deficit/hyperactivity disorder (ADHD) in the DSM-IV and ICD-10, patients with ASD often show ADHD symptoms. We aimed to examine the potential influence of ADHD symptoms on autistic psychopathology in a large sample of patients with ASD. We tested the hypothesis that patients with ASD and an additional ADHD (ASD+) would show a higher severity of autistic symptoms than those with ASD only (ASD-). We measured autistic symptoms using the autism diagnostic observation schedule (ADOS-G), the autism diagnostic interview (ADI-R), and the social responsiveness scale (SRS). To measure overall psychopathology and ADHD symptoms, we used the child behavior checklist (CBCL) and the ADHD rating scale (FBB-ADHS), respectively. Group differences between the ASD+ and the ASD- group (group division was conducted according to the results of the FBB-ADHS) were calculated using a univariate analysis of variance (ANOVA). The ASD+ group showed a greater severity of autistic symptoms than the ASD- group, measured by the SRS and the ADI-R. Especially in the social interaction subscale (ADI-R), a significantly higher symptom severity was found in the ASD+ group. No significant group differences were found regarding autistic symptoms measured by the ADOS-G. Patients with ASD and an additional ADHD expressed a stronger severity of autistic symptoms than patients with ASD only. According to our results, the possibility of a co-diagnosis of ADS and ADHD, as is being planned in the DSM-5, is in line with earlier studies, is highly reasonable, will simplify research, and have therapeutic implications.

Method Secondary analysis of baseline data for a coping skills intervention for school-age children (ages 8-12) with type 1 diabetes (T1D) and their mothers. Children and mothers completed measures of depressive symptoms, coping, quality of life, and family functioning. Results There was a strong relationship between maternal and child depressive symptoms (r = .44, p < .001). Maternal depressive symptoms were negatively related to child quality of life, perceptions of coping, and family functioning. Impact of diabetes on quality of life, upset related to coping, and family warmth mediated the relationship between maternal and child depressive symptoms. Conclusions Maternal depression may negatively affect child adjustment through its influence on quality of life, coping, and family functioning. Implications for interventions to improve psychosocial adjustment in children with T1D are discussed. PMID:17991690

Comparison of post voiding residual volume, lower urinary tract symptoms and quality of life before and after craniosacral therapy revealed a significant improvement (0.001>p>0.0001). CST was found to be an effective means for treating lower urinary tract symptoms and improving quality of life in MS patients. PMID:19341983

    This multicenter study was intended to validate the French version of the M. D. Anderson Symptom Inventory (MDASI-Fr) in French cancer patients (n=162) with solid tumors or hematological malignancies. The European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-C30) was used as a part of the validation. Factor analysis showed three underlying constructs for symptom items: general symptoms (pain, fatigue, disturbed sleep, shortness of breath, drowsiness, dry mouth, and numbness or tingling items); emotional and cognitive components (distress, sadness, and remembering items); and a gastrointestinal component (nausea, vomiting, and lack of appetite items), with Cronbach's alphas of 0.79, 0.73, and 0.71, respectively. Convergent validity was established by comparing MDASI-Fr items with the EORTC QLQ-C30 scale and the Brief Pain Inventory (BPI). Overall, the 19-item MDASI-Fr score correlated well with the QLQ-C30 global health status, and the pain item of the MDASI-Fr was highly correlated with the short form of the BPI. The most prevalent symptoms were fatigue, distress, dry mouth, and pain. Twenty-five percent of patients reported moderate or severe pain (numeric rating scale >4 on 0-10 severity ratings). Physician ratings of global change on a second visit were significantly associated with changes in patient ratings on the MDASI-Fr, supporting the sensitivity of the measure. Symptoms interfered most with work and general activity. The MDASI-Fr is a valid and reliable tool for measuring symptom severity and interference in French cancer patients. PMID:20413059

    Background: Several reports have shown an increased prevalence of gastrointestinal (GI) symptoms in obese subjects in community-based studies. To better understand the role of the GI tract in obesity, and because there are limited clinic-based studies, we documented the prevalence of upper and lower GI symptoms in morbidly obese individuals in a clinic setting. Objective: The aim of our study was to compare the prevalence of GI symptoms in morbidly obese individuals in a weight management clinic with non-obese individuals with similar comorbidities as morbidly obese individuals in an Internal Medicine clinic. Methods: Class II and III obese patients BMI >35 kg/m2 (N = 114) and 182 non-obese patients (BMI <25 kg/m2) completed the GI symptoms survey between August 2011 and April 2012 were included in this study. The survey included 24 items pertaining to upper and lower GI symptoms. The participants rated the frequency of symptoms as absent (never, rarely) or present (occasionally, frequently). The symptoms were clustered into five categories: oral symptoms, dysphagia, gastroesophageal reflux, abdominal pain, and bowel habits. Responses to each symptom cluster were compared between obese group and normal weight groups using logistic regression. Results: Of the 24 items, 18 had a higher frequency in the obese group (p < 0.005 for each). After adjusting for age and gender, the obese patients were more likely to have upper GI symptoms: any oral symptom (OR = 2.3, p = 0.0013), dysphagia (OR 2.9, p = 0.0006), and any gastroesophageal reflux (OR 3.8, p < 0.0001). Similarly, the obese patients were more likely to have lower GI symptoms: any abdominal pain (OR = 1.7, p = 0.042) and altered bowel habits (OR = 2.8, p < 0.0001). Conclusion: These observations suggest a statistically significant increase in frequency of both upper and lower GI symptoms in morbidly obese patients when compared to non-obese subjects.

    2014-01-01

    Benign prostatic hyperplasia (BPH) is a highly prevalent and costly condition that affects older men worldwide. Many affected men develop lower urinary tract symptoms, which can have a negative impact on their quality of life. In the past, transurethral resection of the prostate (TURP) was the mainstay of treatment. However, several efficacious drug treatments have been developed, which have transformed BPH from an acute surgical entity to a chronic medical condition. Specifically, multiple clinical trials have shown that α adrenoceptor antagonists can significantly ameliorate lower urinary tract symptoms. Moreover, 5α reductase inhibitors, alone or combined with an α adrenoceptor antagonist, can reverse the natural course of BPH, reducing the risk of urinary retention and the need for surgical intervention. Newer medical regimens including the use of antimuscarinic agents or phosphodiesterase type 5 inhibitors, have shown promise in men with predominantly storage symptoms and concomitant erectile dysfunction, respectively. For men who do not adequately respond to conservative measures or pharmacotherapy, minimally invasive surgical techniques (such as transurethral needle ablation, microwave thermotherapy, and prostatic urethral lift) may be of benefit, although they lack the durability of TURP. A variety of laser procedures have also been introduced, whose improved hemostatic properties abrogate many of the complications associated with traditional surgery. PMID:25125424

    Psychological and psychiatric problems are well documented across the lifespan of individuals with early-treated phenylketonuria (PKU). Early-treated children and adolescents tend to display attentional problems, school problems, lower achievement motivation, decreased social competence, decreased autonomy, and low-self-esteem. As they enter adulthood, early-treated individuals may carry forward low self-esteem and lack of autonomy but also tend to develop depressed mood, generalized anxiety, phobias, decreased positive emotions, social maturity deficits, and social isolation. The correlation between level of metabolic control and severity of symptoms suggests a biological basis of psychiatric dysfunction. Additionally, psychosocial factors such as the burden of living with a chronic illness may contribute to psychological and psychiatric outcomes in PKU. The lack of a PKU-specific psychiatric phenotype combined with the observation that not everyone with PKU is affected highlights the complexity of the problem. More research on psychiatric and psychological outcomes in PKU is required. Of particular importance is the routine monitoring of emotional, behavioral, and psychosocial symptoms in individuals with this metabolic disorder. Longitudinal studies are required to evaluate the impact of new and emerging therapies on psychiatric and psychosocial functioning in PKU. Unidentified or untreated emotional and behavioral symptoms may have a significant, lifelong impact on the quality of life and social status of patients. PMID:20123472

    Male lower urinary tract symptoms (LUTS) are common, causing significant bother and impair quality of life. LUTS are a spectrum of symptoms that may or may not be due to benign prostatic obstruction (BPO). LUTS are divided into storage, voiding or post micturition symptoms, which each need to be considered in terms of impact, mechanism and treatment options. In most patients, a mixture of symptoms is present. In order to have a better insight about which symptoms are affecting quality of life, a thorough evaluation should include medical history, examination, validated symptom questionnaires, bladder diary, and flow rate (with post void residual measurement). Other tests, particularly urodynamic tests may be needed to guide treatment selection, particularly for surgery. Management of male LUTS is tailored according to the underlying mechanisms. Different treatment modalities are available according to individual patient preference. These range from watchful waiting, behavioral and dietary modifications, and/or medications - either as monotherapy or in combination. Surgery to relieve BPO may be needed where patients have significant bothersome voiding LUTS, and are willing to accept risks associated with irreversible treatment. Interventions for storage LUTS are available, but must be selected judiciously, using particular caution if nocturia is prominent. In order to achieve better outcomes, a rational stepwise approach to decision making is needed. PMID:26654899

    Although the diagnosis of Parkinson disease is based on motor symptoms, it is now well known that non-motor symptoms are an integral part of this pathology, involving in fact multiple systems. These non-motor symptoms affect large population of patients and can appear sometimes before the motor disorders. The non-motor symptoms include mainly neuropsychological difficulties, neuropsychiatric symptoms, and autonomic disorders, but involve also pain and sleep disturbances for example. Depression may occur at any stage of the disease, and consists in major depressive disorder, minor depressive disorder, and dysthymia. During the course of the disease, 50% of patients experience anxiety. Apathy is present in up to 30-40% of patients, due to loss of motivation, appearing in emotional, intellectual and behavioral domains. Dopamine dysregulation syndrome and impulse control disorders are not rare, and in relation with dopaminergic therapies. Impulse control disorders include pathological gambling, hyper sexuality, compulsive shopping, and eating disorder. Visual hallucinations can occur in 30% of patients, mostly induced by dopaminergic therapies. Often, they have deeper impact on the quality of life than the motor symptoms themselves, which stay the focus of attention during consulting. Identifying those can help in providing better care with a positive impact on the quality of life of the patients. PMID:24026132

    2004-12-01

    Three models of the linkage between stressors and depressive symptoms were tested in 252 couples after job loss. Data were analyzed to test whether depressive symptoms in both members of the couple were due to common stressors, the transmission of stress from 1 member to the other, or changes in relationship quality. Evidence was found for all 3 processes. Common stressors influenced depressive symptoms in both partners. Anger and depressive symptoms of each partner partially mediated these effects on the other partner, as did reductions in relationship quality. Findings suggest that interventions to help couples cope with the aftermath of job loss may hold promise for preventing depressive reactions to stress. PMID:15598169

    Our purpose in this study was to identify differences in menopausal symptom management among four major ethnic groups in the U.S. This was a secondary analysis of the qualitative data from a larger Internet-based study. We analyzed data from 90 middle-aged women in the U.S using thematic analysis. We extracted four themes during the data analysis process: (a) “seeking formal or informal advice,” (b) “medication as the first or final choice,” (c) “symptom-specific or holistic,” and (d) “avoiding or pursuing specific foods.” Health care providers need to develop menopausal symptom management programs while considering ethnic differences in menopausal symptom management.

    2013-01-01

    Background Underwater divers are more likely to complain of musculoskeletal symptoms than a control population. Accordingly, we conducted a study to determine whether musculoskeletal symptoms reflected observable physical disorder, to ascertain the relationship between symptoms and measures of mood, memory and executive function and to assess any need for future screening. Methods A 10% random sample of responders to a prior postal health questionnaire was examined (151 divers, 120 non-diving offshore workers). Participants underwent physical examination and a neuropsychological test battery for memory and executive function. Participants also completed the Hospital Anxiety and Depression Scale for anxiety (HADSa) and depression (HADSd), and questionnaires for physical health-related quality of life (SF36 PCS), mental health-related quality of life (SF36 MCS), memory (Cognitive Failures Questionnaire (CFQ), Prospective and Retrospective Memory Questionnaire (PRMQ)), executive function (dysexecutive syndrome questionnaire (DEX)), musculoskeletal symptoms (MSS) and general unrelated symptom reporting. Results Of participants with moderate/severe musculoskeletal symptoms, 52% had physical signs, and of participants with no symptoms, 73% had no physical signs. There was no difference in the prevalence of signs or symptoms between groups. Musculoskeletal symptoms were associated with lower SF36 PCS for both groups. In divers, musculoskeletal symptoms were associated with higher general unrelated symptom reporting and poorer scoring for HADSa, PRMQ, CFQ and DEX with scores remaining within the normative range. A positive physical examination was associated with general unrelated symptom reporting in divers. There were no differences in neuropsychological test scores attributable to either group or musculoskeletal symptoms. Conclusions Musculoskeletal symptoms were associated with physical signs, but this was not a strong effect. Reporting of musculoskeletal symptoms by

    The purpose of the present study was to examine the relationship of several cognitive and emotional variables including perfectionism, rumination, and attachment quality with depressive symptoms in a sample of Iranian undergraduate students. Two hundred and ninety nine undergraduate students (144 males, 156 females) from Urmia University of Technology, Urmia University, and Urmia University of Medical Sciences participated in this study. Participants were asked to complete Tehran Multidimensional Perfectionism Scale (TMPS), Ruminative Responses Scale (RRS), Revised Adult Attachment Scale (RAAS), and Center for Epidemiologic Studies Depression Scale (CES-D). The results demonstrated that insecurity of attachment, socially prescribed perfectionism, and rumination could significantly predict the depressive symptoms in undergraduate students. Confirming predictive risk factors of depressive symptoms, results of the present study can produce an empirical basis for designing educational and health programs for people at risk. Accordingly, proper assessment of the risk factors of depressive symptoms in health care settings may provide invaluable information for prevention and management programs. PMID:25042947

    2013-01-01

    Patients with chronic obstructive pulmonary disease (COPD) present with a variety of symptoms that significantly impair health-related quality of life. Despite this, COPD treatment and its management are mainly based on lung function assessments. There is increasing evidence that conventional lung function measures alone do not correlate well with COPD symptoms and their associated impact on patients’ everyday lives. Instead, symptoms should be assessed routinely, preferably by using patient-centered questionnaires that provide a more accurate guide to the actual burden of COPD. Numerous questionnaires have been developed in an attempt to find a simple and reliable tool to use in everyday clinical practice. In this paper, we review three such patient-reported questionnaires recommended by the latest Global Initiative for Chronic Obstructive Lung Disease guidelines, ie, the modified Medical Research Council questionnaire, the clinical COPD questionnaire, and the COPD Assessment Test, as well as other symptom-specific questionnaires that are currently being developed.

    Although a number of studies have looked at what factors might mediate the relationship between symptoms and quality of life (QoL) in a number of psychiatric disorders, little research has addressed this issue in eating disorders. In the current study, female undergraduates (N = 339) completed questionnaires assessing eating disorder symptoms, social support, coping, QoL, and psychosocial impairment. Perceived family support and levels of substance misuse as a way of coping were identified as mediators of the symptom-impairment relationship and, in addition, maladaptive coping also mediated the relationship with QoL. These results highlight the role of coping and social support in impairment resulting from eating disorder symptoms. PMID:25974054

    Fatigue continues to be one of the main symptoms that afflict ovarian cancer patients and negatively affects their functional status and quality of life. To manage fatigue effectively, the symptom must be understood from the perspective of patients. We utilized text mining to understand the symptom experiences and strategies that were associated with fatigue among ovarian cancer patients. Through text analysis, we determined that descriptors such as energetic, challenging, frustrating, struggling, unmanageable, and agony were associated with fatigue. Descriptors such as decadron, encourager, grocery, massage, relaxing, shower, sleep, zoloft, and church were associated with strategies to ameliorate fatigue. This study demonstrates the potential of applying text mining in cancer research to understand patients' perspective on symptom management. Future study will consider various factors to refine the results. PMID:27332415

    The purpose of this study was to evaluate risk factors for antepartum depressive symptoms that can be assessed in routine obstetric care. We evaluated articles in the Englishlanguage literature from 1980 through 2008. Studies were selected if they evaluated the association between antepartum depressive symptoms and ≥1 risk factors. For each risk factor, 2 blinded, independent reviewers evaluated the overall trend of evidence. In total, 57 studies met eligibility criteria. Maternal anxiety, life stress, history of depression, lack of social support, unintended pregnancy, Medicaid insurance, domestic violence, lower income, lower education, smoking, single status, and poor relationship quality were associated with a greater likelihood of antepartum depressive symptoms in bivariate analyses. Life stress, lack of social support, and domestic violence continued to demonstrate a significant association in multivariate analyses. Our results demonstrate several correlates that are consistently related to an increased risk of depressive symptoms during pregnancy. PMID:20096252

  13. COPD symptoms in the morning: impact, evaluation and management

    PubMed Central

    2013-01-01

    Chronic obstructive pulmonary disease (COPD) symptoms in the morning, including dyspnea and sputum production, affect patients’ quality of life and limit their ability to carry out even simple morning activities. It is now emerging that these symptoms are associated with increased risk of exacerbations and work absenteeism, suggesting that they have a more profound impact on patients than previously thought. The development of validated patient-reported outcome (PRO) questionnaires to capture patients’ experience of COPD symptoms in the morning is, therefore, vital for establishing effective and comprehensive management strategies. Although it is well established that long-acting bronchodilators are effective in improving COPD symptoms, the limited available data on their impact on morning symptoms and activities have been obtained with non-validated PRO questionnaires. In this review, we discuss the impact of COPD symptoms in the morning and available tools used to evaluate them, and highlight specific gaps that need to be addressed to develop standardized instruments able to meet regulatory requirement. We also present available evidence on the effect of pharmacological therapies on morning symptoms. PMID:24143997

    The "Japanese Clinical Guideline for Female Lower Urinary Tract Symptoms," published in Japan in November 2013, contains two algorithms (a primary and a specialized treatment algorithm) that are novel worldwide as they cover female lower urinary tract symptoms other than urinary incontinence. For primary treatment, necessary types of evaluation include querying the patient regarding symptoms and medical history, examining physical findings, and performing urinalysis. The types of evaluations that should be performed for select cases include evaluation with symptom/quality of life (QOL) questionnaires, urination records, residual urine measurement, urine cytology, urine culture, serum creatinine measurement, and ultrasonography. If the main symptoms are voiding/post-voiding, specialized treatment should be considered because multiple conditions may be involved. When storage difficulties are the main symptoms, the patient should be assessed using the primary algorithm. When conditions such as overactive bladder or stress incontinence are diagnosed and treatment is administered, but sufficient improvement is not achieved, the specialized algorithm should be considered. In case of specialized treatment, physiological re-evaluation, urinary tract/pelvic imaging evaluation, and urodynamic testing are conducted for conditions such as refractory overactive bladder and stress incontinence. There are two causes of voiding/post-voiding symptoms: lower urinary tract obstruction and detrusor underactivity. Lower urinary tract obstruction caused by pelvic organ prolapse may be improved by surgery. PMID:26789539

Twenty patients (7 female, 13 male) admitted between January 2012 and February 2014 were enrolled in this study. The mean age of the patients was 34 years (range 28–40). Results The identified symptoms of a discoid lateral meniscus were “pain, stiffness, popping of the knee, feeling that the knee is “giving way”, inability to fully extend (straighten) the knee”. Thirteen patients (65%) had pain, 11 (55%) had popping of the knee, 4 (20%) had stiffness, 2 (10%) had “giving way” feeling, and 1 (5%) had inability to fully extend the knee. These symptoms did not prevent any patient's daily activities. No patients required surgical treatment. Conclusions Pain and popping of the knee were the most common symptoms in patients with a discoid lateral meniscus. The other symptoms were stiffness, feeling that the knee is “giving way”, and inability to fully extend the knee, respectively. No symptoms had been required surgical treatment. PMID:25561753

    2016-01-01

    Skin conditions often have a severe impact on the physical and psychosocial domains of patients' quality of life, but the relationship between these domains has been studied little. This study estimated the fraction of psychosocial burden that may be attributable to symptoms, using the Skindex-17 quality of life questionnaire (symptoms and psychosocial scales) in 2,487 outpatients. The excess proportion of psychosocial burden for each skin condition was computed. Overall, 79.8% of the psychosocial burden of patients with severe symptoms may be attributable to the symptoms. For patients with mild symptoms this figure is 49.7%. A great heterogeneity was observed, from -0.9% for patients with scars, up to more than 90% for conditions such as lichen planus and psoriasis. While these results will have to be confirmed in longitudinal studies, they seem to indicate that, by targeting specific symptoms, a substantial portion of the psychosocial burden of skin diseases could be spared.

    The existing literature on alopecia areata (AA) clearly demonstrates patients' concerns related to physical symptoms, emotional well-being, mental health, social functioning, and other dimensions of daily functioning. Although questionnaires such as the Skindex-16 and the Dermatology Life Quality Index have been used, these questionnaires were validated for skin conditions other than AA as a chronic condition. The goals of this study are to develop a measure of quality of life, symptoms, and their impact for patients with AA called the Alopecia Areata Symptom Impact Scale (AASIS) and to provide psychometric evidence for its use. We used data from 1,400 patients from the National Alopecia Areata Registry together with clinical experts' reviews and quantitative approaches. The preliminary version of the AASIS with 13 items was administered to about 210 patients with AA. Results indicated that the AASIS measures three underlying constructs related to AA. These dimensions were impact of AA, hair loss, and physical skin symptoms. The internal consistency reliabilities of these subscales are 0.93, 0.86, and 0.81, respectively. Cognitive debriefing results showed that patients find the AASIS items easy to understand, clear, and concise. Preliminary evidence suggests that the AASIS is a reliable and valid measure of the symptoms and their impact in patients with AA. PMID:24326557

    Neurovestibular symptoms experienced by astronauts in the post-flight period were examined using data from medical debriefs contained in the NASA Longitudinal Study of Astronaut Health database. Ten symptoms were identified (clumsiness, difficulty concentrating, persisting sensation aftereffects, nausea, vomiting, vertigo while walking, vertigo while standing, difficulty walking a straight line, blurred vision, and dry heaves), of which eight were crossed with twelve demographic parameters (mission duration, astronaut gender, age, one-g piloting experience, previous space flight experience, g-suit inflation, g-suit deflation, in-flight space motion sickness, in-flight exercise, post-flight exercise, mission role, fluid loading). Three symptoms were experienced by a majority of subjects, and another two by more than a quarter of the subjects. Intensity of the symptoms was mild, suggesting that they are unlikely to pose a risk to the crew during landing and the post-flight period. Seven of the symptoms and eight of the parameters under study were found to be significantly associated with each other. PMID:14757912

    A number of neuroanatomical and neurofonctional abnormalities have been evidenced by cerebral imaging studies in patients suffering from schizophrenia. Nevertheless, those specifically associated with the negative symptoms of this disease are still insufficiently known. This work is a review of selected studies that have assessed the brain correlates of negative symptoms in schizophrenia. Approaches using structural imaging have highlighted reduction of gray matter density or cortical thickness associated with negative symptoms, which is rather sparsely distributed within the frontal and temporal regions, localized nevertheless more particularly in the frontal medial and orbitofrontal areas, as well as the amygdalo-hippocampic complex. These deficits are concurrent with a loss of integrity of the principal paths of white matter tracts between frontal and limbic regions. On the other hand, neurofonctional abnormalities associated with negative symptoms involve especially the frontal areas and limbic striatum. A disturbed functioning within the fronto-striatal loops, related to a striatal dopaminergic deficit, may represent a potential explanatory hypothesis of the negative symptoms of schizophrenia, as suggested by studies using Positron Emission Tomography on this topic or neuroimaging studies on the effects of antipsychotics. A better identification of the cerebral abnormalities associated with the negative dimension of schizophrenia, with regard to the lateralization of these abnormalities or to their changes during the course of the disease, could offer new therapeutic modalities for the treatment of this dimension which, until now, remains few responsive to conventional pharmacological treatments.

    Due to elevated ozone concentrations at high altitudes, the adverse effect of ozone on air quality, human perception and health may be more pronounced in aircraft cabins. The association between ozone and passenger-reported symptoms has not been investigated under real conditions since smoking was banned on aircraft and ozone converters became more common. Indoor environmental parameters were measured at cruising altitude on 83 US domestic and international flights. Passengers completed a questionnaire about symptoms and satisfaction with the indoor air quality. Average ozone concentrations were relatively low (median: 9.5 ppb). On thirteen flights (16%) ozone levels exceeded 60 ppb, while the highest peak level reached 256 ppb for a single flight. The most commonly reported symptoms were dry mouth or lips (26%), dry eyes (22.1%) and nasal stuffiness (18.9%). 46% of passengers reported at least one symptom related to the eyes or mouth. A third of the passengers reported at least one upper respiratory symptom. Using multivariate logistic (individual symptoms) and linear (aggregated continuous symptom variables) regression, ozone was consistently associated with symptoms related to the eyes and certain upper respiratory endpoints. A concentration-response relationship was observed for nasal stuffiness and eye and upper respiratory symptom indicators. Average ozone levels, as opposed to peak concentrations, exhibited slightly weaker associations. Medium and long duration flights were significantly associated with more symptoms compared to short flights. The relationship between ultrafine particles and ozone on flights without meal service was indicative of ozone-initiated chemistry. PMID:26011001

    This is the first study to investigate the influence of depression, anxiety and somatization on the treatment response for lower urinary tract symptoms/benign prostatic hyperplasia (LUTS/BPH). The LUTS/BPH patients were evaluated with the Korean versions of the International Prostate Symptom Score (IPSS), the Patient Health Questionnaire-9 (PHQ-9), the 7-item Generalized Anxiety Disorder Scale (GAD-7) and the PHQ-15. The primary endpoint was a responder rate defined by the total score of IPSS (≤ 7) at the end of treatment. The LUTS/BPH severity was significantly higher in patients with depression (whole symptoms P = 0.024; storage sub-symptom P = 0.021) or somatization (P = 0.024) than in those without, while the quality of life (QOL) was significantly higher in patients with anxiety (P = 0.038) than in those without. Anxious patients showed significantly higher proportion of non-response (odds ratio [OR], 3.294, P = 0.022) than those without, while somatic patients had a trend toward having more non-responders (OR, 2.552, P = 0.067). Our exploratory results suggest that depression, anxiety and somatization may have some influences on the clinical manifestation of LUTS/BPH. Further, anxious patients had a lower response to treatment in patients with LUTS/BPH. Despite of limitations, the present study demonstrates that clinicians may need careful evaluation of psychiatric symptoms for proper management of patients with LUTS/BPH.

    Nonmotor symptoms (NMSs) of Parkinson's disease (PD) are common, but they are often underrecognized in clinical practice, because of the lack of spontaneous complaints by the patients, and partly because of the absence of systematic questioning by the consulting physician. However, valid specific instruments for identification and assessment of these symptoms are available in 2012. The administration of the self-completed screening tool, NMSQuest, associated with questioning during the consultation, improves the diagnosis of NMSs. NMSs play a large role in degradation of quality of life. More relevant NMSs are described in this review, mood disorders, impulse control disorders, cognitive deficits, hallucinations, pain, sleep disorders, and dysautonomia. PMID:22888466

    Several studies have reported that depression and anxiety are very common in atrial fibrillation due to impaired quality of life. Dabigatran is an anti-aggregation agent used for the treatment of atrial fibrillation. In terms of drug interactions during treatment with dabigatran, patients suffering from minor depression are reported to be a population at risk. This report is about a 68-year-old man whose depressive symptoms were aggravated after taking dabigatran for atrial fibrillation. The case is discussed in terms of his aggravated depressive symptoms and the interaction between his prescription medications. PMID:25515766

    Metamorphopsia is a common symptom in different macular disorders. Micropsia and macropsia are special types of metamorphopsia. Recent theories suggest that both retinal and cortical mechanisms are involved in the development and changes of metamorphopsia. Different functional tests have been proposed for the evaluation of metamorphopsia: from the Amsler grid to the hand-held mobile devices for home monitoring. This review addresses some new insights into the pathophysiology of metamorphopsia and different available tests for the evaluation of this symptom in most common macular disorders. The importance of quantification of metamorphopsia in macular diseases is confirmed by the most recent therapeutic approaches. PMID:26554918

    Alzheimer's disease (AD) is a neurodegenerative disorder mainly characterized by progressive memory disturbance. Language symptoms are considered to be less disease specific and therefore did not attract many researchers, interest until recently. Typical patients with AD present amnesic aphasia in the early disease stage followed by transcortical sensory aphasia; however, their language symptoms are varied. Recently, the concept of logopenic variant of primary progressive aphasia (PPA) has been developed, which is reported to have Alzheimer's neuropathology. Clinicians should verify patients' language abilities, as language can be the key to reveal their true cognitive functions. PMID:27156508

    Background and Purpose Musculoskeletal problems including shoulder pain are common in the general population and are often cited as reasons for physician visits. Although many risk factors for shoulder pain are postulated, the effects of shoulder pain on functional level and perceived quality of life are poorly characterized in older adults. In this study, we set out to determine the prevalence and impact of shoulder symptoms and dysfunction in an older adult veteran population. Methods A chart review, cross-sectional survey, and examination were performed. A sample of 93 individuals, age >60, were recruited from a primary clinic outpatient waiting room at the Clement J. Zablocki VA Medical Center in Milwaukee, WI. Patients were asked about shoulder symptoms and self-assessed health (SAH), and completed the Stanford Modified Health Assessment Questionnaire (MHAQ). A series of 3 shoulder maneuvers were used to assess shoulder mobility and pain. The presence of diabetes and statin use was documented. A more thorough chart review was performed on individuals who reported shoulder pain and disability. Results Severe shoulder pain was common in the study group, reported by 31% of all participants. Functional limitation measured by the MHAQ and answering “yes” to greater difficulty performing daily tasks was associated with reduced internal rotation, which was present in almost 36% of all participants. Symptoms were often bilateral. No statistically significant risk factors emerged in this small sample, but suggestive trends were apparent. Interestingly, few patients reported discussing these problems with their providers, and shoulder-related problems were documented in only 10% of corresponding problem lists of symptomatic patients. Conclusions With an aging population, the high prevalence of shoulder pain may have considerable impact on public health. It will become increasingly important to define risk factors, delineate etiologies, and devise new management

    The purpose of this study was to examine the relationships among subclinical PTSD symptoms, blood pressure, and several variables linked to both frank PTSD and the basic psychobiological adaptation to stress. The authors recruited a sample of 91 healthy, young men and women between 18 and 35 years. We examined links among subclinical posttraumatic stress disorder symptoms, blood pressure, sleep quality, and hostility. Posttraumatic stress disorder symptoms were associated with poorer sleep quality and higher hostility scores in both women and men. In men, PTSD symptoms were also associated with elevated resting diastolic blood pressure, and sex was an important moderator of that relationship. Moreover, sleep quality and hostility are substantive mediators of the relationship between diastolic blood pressure and PTSD. Behavioral interventions designed to increase sleep quality and restructure hostile attitudes could potentially serve as preventive interventions for PTSD and the underlying cardiovascular comorbidities in young adults.

    Adolescents and young adults (AYAs) with cancer experience multiple distressing symptoms during treatment. Because the typical approach to symptom assessment does not easily reflect the symptom experience of individuals, alternative approaches to enhancing communication between the patient and provider are needed. We developed an iPad-based application that uses a heuristic approach to explore AYAs' cancer symptom experiences. In this mixed-methods descriptive study, 72 AYAs (13-29 years old) with cancer receiving myelosuppressive chemotherapy used the Computerized Symptom Capture Tool (C-SCAT) to create images of the symptoms and symptom clusters they experienced from a list of 30 symptoms. They answered open-ended questions within the C-SCAT about the causes of their symptoms and symptom clusters. The images generated through the C-SCAT and accompanying free-text data were analyzed using descriptive, content, and visual analyses. Most participants (n = 70) reported multiple symptoms (M = 8.14). The most frequently reported symptoms were nausea (65.3%), feeling drowsy (55.6%), lack of appetite (55.6%), and lack of energy (55.6%). Forty-six grouped their symptoms into one or more clusters. The most common symptom cluster was nausea/eating problems/appetite problems. Nausea was most frequently named as the priority symptom in a cluster and as a cause of other symptoms. Although common threads were present in the symptoms experienced by AYAs, the graphic images revealed unique perspectives and a range of complexity of symptom relationships, clusters, and causes. Results highlight the need for a tailored approach to symptom management based on how the AYA with cancer perceives his or her symptom experience. PMID:26455729

  3. Daytime intrusive thoughts and subjective insomnia symptoms.

    2015-10-30

    Insomnia is increasingly recognised as a 24h complaint that is associated with an increased risk of mood and anxiety disorders. However, the effects of insomnia symptoms on maladaptive daytime patterns of thinking are poorly understood. We examined the relationship between subjective insomnia symptoms, attentional control and negative thought intrusions during daytime in a large sample of undergraduates experiencing poor sleep. A total of 109 participants completed self-report measures of sleep quality, current sleepiness, anxiety and attentional control. A behavioural measure of intrusive thought required participants to control their attention during two focus periods separated by a 5min period of self-referential worry. Thought intrusions were sampled throughout the pre- and post-worry periods. Perceived insomnia severity was associated with the reduced ability to focus attention and uniquely associated with increased negative thought intrusions in the pre-worry period. These results support suggestions that acute episodes of poor sleep can dysregulate key networks involved in attentional control and emotion regulation, and that promote negative cognitive activity.

    Stress incontinence is a common problem among women, yet there is no adequately validated instrument for measuring women's views of its severity (disease-specific health status). The only instrument for measuring the impact or bothersomeness of symptoms (disease-specific quality of life) has poor internal consistency. This paper describes the development and psychometric assessment of two new indexes, a Symptom Severity Index and a Symptom Impact Index. Following several qualitative enquiries, a questionnaire was developed and administered to 442 women undergoing stress incontinence surgery. The face and content validity of the items comprising the indexes was good. The Severity Index (0-20) showed good variability (median 14, interquartile range 6) and adequate internal consistency (alpha 0.76). The Impact Index (0-12) also had good variability (median 5, interquartile range 3.5) and internal consistency (alpha 0.80). Convergent and discriminant validity were demonstrated for both indexes. Test-retest reliability was high. While responsiveness is still to be tested, the two indexes are psychometrically strong and can be used to measure the severity and impact of stress incontinence in women. PMID:8916115

    2012-01-01

    Purpose Myeloproliferative neoplasm (MPN) symptoms are troublesome to patients, and alleviation of this burden represents a paramount treatment objective in the development of MPN-directed therapies. We aimed to assess the utility of an abbreviated symptom score for the most pertinent and representative MPN symptoms for subsequent serial use in assessing response to therapy. Patients and Methods The Myeloproliferative Neoplasm Symptom Assessment Form total symptom score (MPN-SAF TSS) was calculated as the mean score for 10 items from two previously validated scoring systems. Questions focus on fatigue, concentration, early satiety, inactivity, night sweats, itching, bone pain, abdominal discomfort, weight loss, and fevers. Results MPN-SAF TSS was calculable for 1,408 of 1,433 patients with MPNs who had a mean score of 21.2 (standard deviation [SD], 16.3). MPN-SAF TSS results significantly differed among MPN disease subtypes (P < .001), with a mean of 18.7 (SD, 15.3), 21.8 (SD, 16.3), and 25.3 (SD, 17.2) for patients with essential thrombocythemia, polycythemia vera, and myelofibrosis, respectively. The MPN-SAF TSS strongly correlated with overall quality of life (QOL; r = 0.59; P < .001) and European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire C30 (EORTC QLQ-C30) functional scales (all P < .001 and absolute r ≥ 0.50 except social functioning r = 0.48). No significant trends were present when comparing therapy subgroups. The MPN-SAF TSS had excellent internal consistency (Cronbach's α = .83). Factor analysis identified a single underlying construct, indicating that the MPN-SAF TSS is an appropriate, unified scoring method. Conclusion The MPN-SAF TSS is a concise, valid, and accurate assessment of MPN symptom burden with demonstrated clinical utility in the largest prospective MPN symptom study to date. This new prospective scoring method may be used to assess MPN symptom burden in both clinical practice and trial settings. PMID

  10. Psychosocial treatments for negative symptoms in schizophrenia: Current practices and future directions

    2014-01-01

    Schizophrenia can be a chronic and debilitating psychiatric disorder. Though advancements have been made in the psychosocial treatment of some symptoms of schizophrenia, people with schizophrenia often continue to experience some level of symptoms, particularly negative symptoms, throughout their lives. Because negative symptoms are associated with poor functioning and quality of life, the treatment of negative symptoms is a high priority for intervention development. However, current psychosocial treatments primarily focus on the reduction of positive symptoms with comparatively few studies investigating the efficacy of psychosocial treatments for negative symptoms. In this article, we review and evaluate the existing literature on three categories of psychosocial treatments – cognitive behavioral therapy (CBT), social skills training (SST), and combined treatment interventions – and their impact on the negative symptoms of schizophrenia. Of the interventions reviewed, CBT and SST appear to have the most empirical support, with some evidence suggesting that CBT is associated with maintenance of negative symptom improvement beyond six months after treatment. It remains unclear if a combined treatment approach provides improvements above and beyond those associated with each individual treatment modality. Although psychosocial treatments show promise for the treatment of negative symptoms, there are many unanswered questions about how best to intervene. We conclude with a general discussion of these unanswered questions, future directions and methodological considerations, and suggestions for the further development of negative symptom interventions.

  11. Addressing the unmet needs of patients with persistent negative symptoms of schizophrenia: emerging pharmacological treatment options

    PubMed Central

    2014-01-01

    The negative symptoms of schizophrenia represent an impairment of normal emotional responses, thought processes and behaviors, and include blunting or flattening of affect, alogia/aprosody, avolition/apathy, anhedonia, and asociality. Negative symptoms contribute to a reduced quality of life, increased functional disability, increased burden of illness, and poorer long-term outcomes, to a greater degree than positive symptoms. Primary negative symptoms are prominent and persistent in up to 26% of patients with schizophrenia, and they are estimated to occur in up to 58% of outpatients at any given time. Negative symptoms respond less well to medications than positive symptoms, and to date treatment options for negative symptoms have been limited, with no accepted standard treatment. Modest benefits have been reported with a variety of different agents, including second-generation antipsychotics and add-on therapy with antidepressants and other pharmacological classes. Recent clinical research focusing on negative symptoms target novel biological systems, such as glutamatergic neurotransmission. Different approaches include: enhancing N-methyl-D-aspartate receptor function with agents that bind directly to the glycine ligand site or with glycine reuptake inhibitors; influencing the metabotropic glutamate receptor (mGluR2/3) with positive allosteric modulators; and stimulating nicotinic acetylcholine receptors. In conclusion, the lack of clearly efficacious pharmacological treatments for the management of negative symptoms represents a significant unmet need, especially considering the importance of these symptoms on patient outcomes. Hence, further research to identify and characterize novel pharmacological treatments for negative symptoms is greatly needed. PMID:24855363

    2015-08-01

    The skin is one of the organs most frequently involved in vasculitides. Cutaneous vasculitis may present (1) part of a systemic vasculitis (e.g., IgA vasculitis), (2) a skin-restricted or skin-dominant variant of the corresponding systemic vasculitis without clinically apparent visceral involvement (e.g., cutaneous IgA vasculitis), or (3) a vasculitis occurring exclusively in the skin (e.g., erythema elevatun diutinum). The clinical symptoms of vasculitides are markedly determined by the size of the predominantly affected blood vessels. Systemic polyarteritis nodosa is regarded as a medium vessel vasculitis and is associated with multiple skin symptoms: (1) vasculitis of digital arteries with ensuing digital infarction, (2) livedo racemosa and subcutaneous nodules, and (3) in some patients even purpura and hemorrhagic macules due to additional small vessel vasculitis. In contrast, in its skin-restricted entity (i.e., cutaneous polyarteritis nodosa), the predominant symptoms are subcutaneous nodules surrounded by livedo racemosa, often on the lower legs. Among small-vessel vasculitides palpable purpura with predilection for the legs is a nearly pathognomonic feature of immune complex vasculitis. Variations in clinical symptoms indicate additional pathophysiological mechanisms or different vascultides: (1) ANCA-associated vasculitides often also entail nodules or sometimes livedo, (2) cryoglobulinemic vasculitis additionally may present with necrosis at cold exposed areas and involvement of vessels of various size, (3) small vessel vasculitis associated with systemic lupus erythematosus or rheumatoid arthritis shows predilection for additional sites (e.g., nailfolds) and also involvement of vessels beyond postcapillary venules, (4) recurrent macular vasculitis in hypergammaglobulinemia also occurs on dependent parts, but shows numerous small hemorrhagic macules instead of palpable purpura, (5) erythema elevatum diutinum begins with brightly red to violaceous plaques

    2014-01-01

    Aims and objectives To examine how subgroups of patients with chronic obstructive pulmonary disease, identified by ratings of symptoms (dyspnoea, anxiety, depression and fatigue), affect healthcare use and mortality. Background People with chronic obstructive pulmonary disease often experience multiple symptoms. The importance of multiple symptoms and symptom clusters has received increased attention. However, little is known about symptom clusters and their effect on healthcare use and mortality in this population. Design Descriptive cross-sectional study. Methods This secondary data analysis used data from the National Emphysema Treatment Trial. Participants (n = 597) had severe chronic obstructive pulmonary disease. Descriptive and inferential statistics were used to analyse the data that were drawn from structured interviews, questionnaires and clinical measures. Results Three subgroup clusters emerged based on four symptom ratings. Mean age, proportion with higher education, proportion using oxygen, disease severity, exercise capacity and quality of life differed significantly between subgroups. Participants with high levels of symptoms used healthcare services more and were more likely to have died at the five-year follow-up than those with low levels of symptoms. Symptom cluster subgroups had more significant relationship with mortality than single symptoms. Conclusion Patients with high levels of symptoms require greater clinical attention. Relevance to clinical practice Understanding subgroups of patients, based on symptom ratings and their adverse effect on outcomes, may enable healthcare providers to assess multiple symptoms and identify subgroups of patients at risk of increased healthcare use and mortality. Targeting modifiable symptoms within the cluster may be more beneficial than focusing on a single symptom for certain health-related outcome. PMID:24460846

    Context: Depression is common after concussion and is associated with functional outcome and quality of life after injury. However, few baseline predictors of postconcussion depressive symptoms (PCDS) have been found. Objective: To describe the prevalence of depressive symptoms in a collegiate athlete sample at baseline and postconcussion, compare these levels of symptoms and change in symptoms with those of a control group with no reported concussions in the past year, and examine the baseline predictors for PCDS. Design: Case-control study. Setting: Undergraduate institution. Patients or Other Participants: Participants were 84 collegiate athletes (65 men, 19 women) with concussion and 42 individuals (23 men, 21 women) with no history of recent concussion who served as controls. Main Outcome Measure(s): The Beck Depression Inventory–Fast Screen was administered to the concussion group at baseline and postconcussion and to the control group at 2 time points. Results: Seventeen athletes (20%) showed a reliable increase in depression, and more athletes reported clinically important depression postconcussion than at baseline. Only 2 participants (5%) in the control group showed a reliable increase in depression. Concussed athletes were more likely to show a reliable increase in depression symptoms than control participants (χ21 = 5.2, P = .02). We also found several predictors of PCDS in the athletes, including baseline depression symptoms (r = 0.37, P < .001), baseline postconcussion symptoms (r = 0.25, P = .03), estimated premorbid intelligence (full-scale IQ; r = −0.29, P = .009), and age of first participation in organized sport (r = 0.34, P = .002). For the control group, predictors of depression symptoms at time 2 were number of previous head injuries (r = 0.31, P = .05) and baseline depression symptoms (r = 0.80, P < .001). Conclusions: A large proportion of athletes showed a reliable increase in depression after concussion, and we identified several

    The BCR-ABL-negative myeloproliferative neoplasms (MPNs) are clonal stem cell derived malignancies, which include polycythemia vera (PV), essential thrombocythemia (ET), and myelofibrosis (MF). The MPNs are characterized by dysregulated JAK-STAT signaling pathways. PV and ET are associated with an increased risk of thrombo-hemorrhagic complications, risk of progression to MF and leukemia. Presentation of patients with PV and ET is variable and usually as a result of abnormal full blood count indices (raised hemoglobin and hematocrit, leukocytosis, and thrombocytosis). Presentation with thrombosis or splenomegaly occurs in ~30% of patients. Historically thought of as indolent compared with MF, patients with PV and ET have significant disease symptom burden which does not directly correlate to the current clinical prognostic classifications. The mainstay of therapy is reserved for patients with high-risk disease and thus excludes a population of patients with significant symptom related morbidity impacting their quality-of-life and survival. Recent treatment strategies have aimed to incorporate disease burden assessment into the selection of therapeutic interventions such as JAK2 inhibitors and HDAC inhibitors. We will review the advances in the field of MPN symptom assessment and symptom burden experienced by ET and PV patients. We will also discuss the risk-stratified management of ET and PV patients alongside symptom assessment and the impact of potential novel therapies, for patients who fail to respond to conventional treatment.

    Purpose: To analyze the cause of GI symptoms after pelvic radiotherapy (RT) in a consecutive series of patients with symptoms beginning after RT. A striking lack of evidence is available concerning the optimal treatment for the 50% of patients who develop permanent changes in bowel habits affecting their quality of life after pelvic RT. As a result, in the UK, most such patients are never referred to a gastroenterologist. Methods and Materials: All diagnoses were prospectively recorded from a consecutive series of patients with symptoms that started after RT and who were referred during a 32-month period to a gastroenterology clinic. Patients either underwent direct access flexible sigmoidoscopy or were investigated in a standard manner by one gastroenterologist after first being seen in the clinic. Results: A total of 265 patients referred from 15 institutions were investigated. They included 90 women (median age, 61.5 years; range, 22-84 years) and 175 men (median age, 70 years; range, 31-85 years). RT had been completed a median of 3 years (range, 0.1-34 years) before the study in the women and 2 years (range, 0-21 years) before in the men. Of the 265 patients, 171 had primary urologic, 78 gynecologic, and 16 GI tumors. The GI symptoms included rectal bleeding in 171, urgency in 82, frequency in 80, tenesmus, discomfort, or pain in 79, fecal incontinence in 79, change in bowel habit in 42, weight loss in 19, vomiting without other obstructive symptoms in 18, steatorrhea in 7, nocturnal defecation in 8, obstructive symptoms in 4, and other in 24. After investigation, significant neoplasia was found in 12%. One-third of all diagnoses were unrelated to the previous RT. More than one-half of the patients had at least two diagnoses. Many of the abnormalities diagnosed were readily treatable. The symptoms were generally unhelpful in predicting the diagnosis, with the exception of pain, which was associated with neoplasia (p < 0.001). Conclusion: The results of our

    Introduction: Menopausal symptoms experienced by women are known to affect their quality-of-life. The symptoms experienced at menopause are quite variable and their etiology is found to be multifactorial. This study was hence done to assess the pattern and severity of menopausal symptoms and to find out the factors associated with these symptoms. Materials and Methods: This cross-sectional study was conducted in various outreach clinics of Kasturba Medical College, Mangalore. Women in the age group of 40-65 years were included in the study by convenient sampling method. Data regarding menopausal symptom was obtained by interviewing each participant using the menopause rating scale questionnaire. Results: Mean age of the participants were 54.2 ± 7.2 years and mean age of attainment of menopause was 48.4 ± 4.5 years. Mean duration of menopause was found to be 7.5 ± 5.3 years. Commonest symptom reported was joint and muscular discomfort and physical and mental exhaustion seen in 94 (85.4%) participants. The mean number of symptoms reported by participants was 7.6 ± 2.8. Educated women reported significantly more symptoms (F = 2.218, P = 0.047). Somatic and urogenital symptoms were more among perimenopausal women and somatic symptoms were more among postmenopausal women. Fifty-eight (52.7%) participants had one or more severe symptoms. Severe symptoms were most among premenopausal women. Conclusion: The high proportion and severity of menopausal symptoms observed in this study group proves that menopausal symptoms are common and cannot be ignored. More of menopausal clinics are needed for awareness generation, early recognition and treatment of related morbidities. PMID:24970987

    Objective: To examine the prevalence of nightmares in people with psychosis and to describe the link between nightmares and sleep quality, psychotic, affective, and cognitive symptoms. Methods: Forty participants with psychotic symptoms completed an assessment of nightmares, sleep quality, positive symptoms of psychosis, affect, posttraumatic stress, social functioning, and working memory. Results: Among the patients, 55% reported weekly distressing nightmares. Experience of more frequent nightmares was related to poorer sleep quality and sleep efficiency. More distressing nightmares were positively associated with greater delusional severity, depression, anxiety, stress, and difficulties with working memory. Conclusions: Nightmares might be common in those with psychosis and are associated with increased day- and nighttime impairment. Future research should investigate treatments for nightmares, for people presenting with psychotic symptoms. PMID:26454557

    Gastrointestinal (GI) hypomotility and symptoms are common in Scleroderma (SSc) patients yet so far uncorrelated. Eight SSc patients and matched controls were queried about their GI dysmotility symptoms and quality of life (QoL) and underwent anorectal motility and sensory tests. Specific scoring systems were developed for anorectal symptoms and anorectal dysmotility. We found that (1) the SSc patients showed low QoL and marked overall GI symptoms. The most common anorectal symptom was incomplete bowel movement (50%). (2) Compared to normal controls, SSc patients showed impaired anorectal pressures, sensations, and rectal compliance (P ≤ .01 for each). (3) The anorectal motility/sensation abnormality score was robustly correlated with the total anorectal symptom score (rs = .78, P = .02). In conclusion, scleroderma patients have impaired anorectal motor and sensory functions, and the abnormality score of these anorectal functions is correlated with the total anorectal symptoms score. These scoring systems may assist clinicians in predicting dysmotility based on patient symptoms. PMID:21991506

    Purpose: To investigate the relationship between linear energy transfer (LET) and relative biological effectiveness (RBE) for protons and light ions, and the corresponding role of LET as a descriptor of radiation quality of hadron therapy. Methods: Monte Carlo (MC) proton and light ion (He, Li, C) tracks with LET < 30 eV nm{sup -1} were generated in an event-by-event mode. They were overlaid on a cell nucleus model containing 6×10{sup 9} nucleotide base pairs using an isotropic irradiation procedure that provides electronic equilibrium. Strand breaks (sbs) were scored in the DNA sugar-phosphate groups and further sub-classified into single or double sbs (ssbs or dsbs). Distributions of ssbs and dsbs for 2 Gy fractions were calculated to estimate RBE for the induction of initial dsbs with reference to {sup 60}Co. Additionally, sbs were classified based on their complexity (i.e. the number of sbs in each cluster). Results: An increase in LET for light ions of the same atomic number or a decrease in atomic number for ions of the same LET resulted in a lower kinetic energy of emitted secondary electrons. The clustering of DNA damage was more pronounced as reflected by the increase in proton RBE from ∼ 1.75 to 4 for LET values of 7 to 28 eV nm{sup -1}. A significant RBE decrease between protons, He, Li and C ions of the same LET was also noticed as function of the atomic number. Significant differences in ssbs and dsbs complexities were also seen for particles with the same LET, potentially supporting a clustering-based radiation quality descriptor. Conclusion: The LET-RBE relationships were simulated for proton and light ions and exhibited expected trends, including different RBEs for particles with the same LET but different atomic numbers. A complexity based radiation quality descriptor may allow better differentiation of RBE between radiation fields of similar LET.

    2013-06-01

    Although effective treatments for negative symptoms are currently limited, clinicians still need to assess and monitor them because of their impact on patient functioning. Further, documenting patients' negative symptoms provides a complete clinical record that the clinician can use to make systematic and careful treatment decisions. Several tools for assessing negative symptoms in schizophrenia are available, including the Clinical Global Impression scale (CGI), the Brief Psychiatric Rating Scale (BPRS), the Positive and Negative Syndrome Scale (PANSS), the Scale for the Assessment of Negative Symptoms (SANS), the 16-item Negative Symptoms Assessment (NSA-16), and the Schedule for Deficit Syndrome (SDS). Additionally, newer instruments are in development-the Clinical Assessment Interview for Negative Symptoms (CAINS) and the Brief Negative Symptoms Scale (BNSS)-and are yielding promising results. This overview outlines these assessment tools so that clinicians can measure negative symptom severity and track treatment response for their patients with schizophrenia. PMID:23842020

    Cancer survivors often experience symptoms related to hormone deprivation, including vasomotor symptoms, genitourinary symptoms, and sexual health concerns. These symptoms can occur due to natural menopause in midlife women, or they can be brought on by oncologic therapies in younger women or men. We searched PubMed for English-language studies from January 1990 through January 2016 to identify relevant articles on the management of hormone deprivation symptoms, including vasomotor, genitourinary, and sexual symptoms in patients with cancer. The search terms used included hormone deprivation, vasomotor symptoms, hot flash, vaginal dryness, sexual dysfunction, and breast cancer. This manuscript provides a comprehensive description of data supporting the treatment of symptoms associated with hormone deprivation. PMID:27492917

    Background: One of the main criteria to verify the effectiveness of a health training program is to measure quality of life in menopausal women. Objectives: Hence the aim of this review was to evaluate the effects of self-directed learning (SDL) on MENQOl. Patients and Methods: The present single blind field study was conducted in Saadatmandi Health Center of Robat Karim (Iran, Southwest of Tehran Province) from August to December 2010. One handred and ten menopausal women were selected using convenience sampling method and then divided into two experimental (Self-directed Learning) and control groups of 55 each. Four manuals were developed to guide the women in the experimental group containing practical ways to treat menopausal symptoms. They were distributed among the participants for four weeks on a specific day. Menopausal Specific Quality of Life Questionnaire (MENQOL) was used to determine and compare quality of life scores of these women (before and three months after intervention sessions). The control group did not receive any intervention. Statistical analysis was performed by SPSS/16 software using Kolmogorov-Sminov, ANOVA, independent paired t test and Chi-square test. Results: There were significant statistical differences between two groups regarding the age of subjects; age of menopause; economic, educational and employment status; number of dead and living children; BMI and vasomotor, physical, sexual and psycho-social postmenopausal symptoms. The implementation of Self-directed Learning (SDL) model leads to a significant statistical difference in scores of vasomotor symptoms (16.32 ± 5.92 to 13.26 ± 5.31), psychosocial symptoms (34.8 ± 11 to 27.18 ± 10.83), physical symptoms (75.02 ± 18.07 to 61.42 ± 15.49), sexual symptoms (15.36 ± 6.10 to 12.00 ± 4.97) and the overall score for quality of life (141.5 ± 41.09 to 113.86 ± 36.6) (P < 0.001). No significant changes were found in the QOL scores of the control group. Conclusions

    Outpatient adolescent asthmatics were studied using the Asthma Symptom Checklist (ASC) of Kinsman et al. The study showed that outpatient asthmatic adolescents are similar in many respects to older institutionalized asthmatics, except that in the former, psychological symptoms are more diffuse and recognition of respiratory symptoms is less severe. Further studies are needed to determine which psychological symptoms are most important in predicting prognosis in affected asthmatics or the development of "psychosomatic" asthma. PMID:7338897
