Poorer Quality (poorer + quality)
Selected AbstractsInvestigation of quality of the parental relationship as a risk factor for subclinical bulimia nervosaINTERNATIONAL JOURNAL OF EATING DISORDERS, Issue 4 2001Tracey D. Wade Abstract Objective Previous literature suggests a link between the quality of the parental relationship and disordered eating in offspring. We investigated the relationship between offspring pyschopathology and the parental relationship using a population-based twin registry that contained 766 complete twin pairs. Method We used reports of twin lifetime psychopathology from the twins and quality of parental relationship and parental lifetime psychopathology from both parents. Results Poorer quality of the marital relationship predicted the presence of subclinical bulimia nervosa (SBN) using both mother's (odds ratio [OR] = 0.83, 95% confidence interval [CI]: 0.71,0.97) and father's (OR = 0.78, 95% CI: 0.62,0.97) reports. It also predicted the presence of generalized anxiety disorder (GAD) and alcohol dependence. SBN was still strongly predicted by the marital relationship when parental psychopathology was included as a covariate. Discussion These results are supportive of the notion that a conflictual and distant marital relationship can, at least partially, act as an environmental risk factor for SBN. © 2001 by John Wiley & Sons, Inc.

[source] Longitudinal validity and responsiveness of the Food Allergy Quality of Life Questionnaire , Parent Form in children 0,12 years following positive and negative food challengesCLINICAL & EXPERIMENTAL ALLERGY, Issue 3 2010A. DunnGalvin Summary Background There are no published studies of longitudinal health-related quality of life (HRQL) assessments of food-allergic children using a disease-specific measure. Objective This study assessed the longitudinal measurement properties of the Food Allergy Quality of Life Questionnaire , Parent Form (FAQLQ-PF) in a sample of children undergoing food challenge. Methods Parents of children 0,12 years completed the FAQLQ-PF and the Food Allergy Independent Measure (FAIM) pre-challenge and at 2 and 6 months post food challenge. In order to evaluate longitudinal validity, differences between Group A (positive challenge) and Group B (negative challenge) were expected over time. We computed correlation coefficients between change scores in the FAQLQ-PF and change scores in the FAIM. To determine the minimally important difference (MID), we used distributional criterion and effect size approaches. A logistic regression model profiled those children falling below this point. Results Eighty-two children underwent a challenge (42 positive; 40 negative). Domains and total score improved significantly at pos-challenge time-points for both groups (all P<0.05). Sensitivity was demonstrated by significant differences between positive and negative groups at 6 months [F(2, 59)=6.221, P<0.003] and by differing improvement on relevant subscales (P<0.05). MID was 0.45 on a seven-point response scale. Poorer quality of life at baseline increased the odds by over 2.0 of no improvement in HRQL scores 6-month time-point. General maternal health (OR 1.252), number of foods avoided (OR 1.369) and children >9 years (OR 1.173) were also predictors. The model correctly identified 84% of cases below MID. Conclusion The FAQLQ-PF is sensitive to change, and has excellent longitudinal reliability and validity in a food-allergic patient population. The standard error of measurement value of 0.5 points as a threshold for meaningful change in HRQL questionnaires was confirmed. The FAQLQ-PF may be used to identify problems in children, to assess the effectiveness of clinical trials or interventions, and to guide the development of regulatory policies. Cite this as: A.

[source] Sexual dysfunction and physicians' perception in medicated patients with major depression in TaiwanDEPRESSION AND ANXIETY, Issue 9 2008Kao Ching Chen M.D. Abstract Although prevalent during antidepressant treatment, sexual dysfunction (SD) is frequently ignored by both physicians and patients in Asia. In spite of impact of SD on medicated patients with major depression, sexual issues and illness remain a forbidden topic for most Asian people. The aims of this study were to: (1) estimate the prevalence of SD among stable outpatients taking different antidepressants in Taiwan; (2) investigate the factors related to SD; (3) compare physician-perceived with patient-reported prevalence rates of antidepressant-associated SD; and (4) study the differences of SD among antidepressant subgroups. In this cross-sectional observational study, 125 medicated patients with major depression were recruited. Patients were assessed using the Changes in Sexual Functioning Questionnaire (CSFQ), Taiwanese Depression Questionnaire (TDQ), Quality of Life Index (QOL), and neuroticism scores in the Maudsley Personality Inventory (MPI). Sixty-two physicians completed the Physician Antidepressant Experience Questionnaire. The estimated prevalence rate of SD was 53.6% (95% CI = 44.9,62.3%) in medicated patients with major depression. There were no significant differences in prevalence rate of SD among different antidepressants. The SD subgroup had poorer quality of life and lower moods than the non-dysfunction subgroup. An underestimation of the prevalence of SD by physicians was noted. Because antidepressant-associated SD is highly prevalent and seriously underestimated by physicians, greater physicians' recognition and better patients' education are imperative when prescribing antidepressants. Depression and Anxiety. © 2007 Wiley-Liss, Inc. [source] Irritability is associated with anxiety and greater severity, but not bipolar spectrum features, in major depressive disorderACTA PSYCHIATRICA SCANDINAVICA, Issue 4 2009R. H. Perlis Objective:, Irritability is common during major depressive episodes, but its clinical significance and overlap with symptoms of anxiety or bipolar disorder remains unclear. We examined clinical correlates of irritability in a confirmatory cohort of Sequenced Treatment Alternatives to Relieve Depression (STAR*D) study participants with major depressive disorder (MDD). Method:, Logistic regression was used to identify features associated with presence of irritability on the clinician-rated Inventory of Depressive Symptomatology. Results:, Of 2307 study participants, 1067(46%) reported irritability at least half the time during the preceding week; they were more likely to be female, to be younger, to experience greater depression severity and anxiety, and to report poorer quality of life, prior suicide attempts and suicidal ideation. Bipolar spectrum features were not more common among those with irritability. Conclusion:, Irritable depression is not a distinct subtype of MDD, but irritability is associated with greater overall severity, anxiety comorbidity and suicidality. [source] Parental psychopathology and self-rated quality of life in adolescents with epilepsy in NigeriaDEVELOPMENTAL MEDICINE & CHILD NEUROLOGY, Issue 7 2006Abiodun O Adewuya MBChB This study sought to investigate the relationship between parental psychopathology and health-related quality of life in a group of Nigerian adolescents with epilepsy. The participants were 86 adolescents with epilepsy (50 males, 36 females; mean age 14y 5mo [SD 2y 1mo]; age range 12,18y). There were 54 (62.8%) adolescents with complex partial seizures, six (7.0%) with simple partial seizures, 14 (16.3%) with generalized tonic-clonic seizures, four (4.7%) with absence seizures, and eight (9.2%) with other types of seizure. They completed the Quality of Life in Epilepsy Inventory for Adolescents (QOLIE-AD-48). Parents also completed the General Health Questionnaire, Zung's Self-Rating Anxiety Scale, and Zung's Self-Rating Depressive Scale as measures of their psychopathology. Factors correlating with poor overall quality of life in the adolescents include longer duration of illness, large number of antiepileptic drugs, more severe medication toxicity, and psychopathology in the parents. General psychopathology in parents is significantly associated with QOLIE-AD-48 subscales of Epilepsy Impact (r= 0.527, p < 0.001), Attitude (r= 0.214, p= 0.047), Physical Function (r= 0.417, p < 0.001), Stigma (r= 0.305, p= 0.004), Social Support (r= 0.365, p= 0.001), and School Behaviour (r= 0.220, p= 0.042). There is a possibility of a cross-cultural difference on the effect of epilepsy on the quality of life of adolescents. Psychopathology in parents is significantly associated with poorer quality of life of these adolescents. Physicians should consider this, therefore, when planning intervention strategies in improving the quality of life in adolescents with epilepsy. [source] Psychopathological changes and quality of life in hepatitis C virus-infected, opioid-dependent patients during maintenance therapyADDICTION, Issue 4 2009Arne Schäfer ABSTRACT Aims To examine among maintenance patients (methadone or buprenorphine) with and without hepatitis C virus (HCV) infection (i) the frequency of psychopathological symptoms at baseline and 1-year follow-up; (ii) the association between antiviral interferon (IFN) treatment and psychopathological symptoms; and (iii) to explore whether IFN therapy has an effect on 1-year outcome of maintenance treatment. Design Naturalistic prospective longitudinal cohort design. Setting A total of 223 substitution centres in Germany. Participants A nationally representative sample of 2414 maintenance patients, namely 800 without and 1614 with HCV infection, of whom 122 received IFN therapy. Measures HCV infection (HCV+/HCV - ), IFN (IFN+/IFN - ) treatment status and clinical measures. Diagnostic status and severity (rated by clinician), psychopathology (BSI,Brief Symptom Inventory) and quality of life (EQ-5D,EuroQol Group questionnaire). Findings HCV+ patients revealed indications for a moderately increased psychopathological burden and poorer quality of life at baseline and follow-up compared to HCV - patients. HCV+ patients showed a marked deterioration over time only in the BSI subscale somatization (P = 0.002), and the frequency of sleep disorders almost doubled over time (12.8% at baseline; 24.1% at follow-up; P < 0.01). IFN treatment, received by 10% of HCV+ patients, did not impair efficacy or tolerability of maintenance therapy and was associated overall with neither increased psychopathological burden nor reduced quality of life. Conclusions Findings suggest no increased risk among HCV+ patients on maintenance therapy for depressive or other psychopathological syndromes. In our patient sample, IFN treatment was not associated with increased psychopathological burden, reduced quality of life or poorer tolerability and efficacy of maintenance treatment. [source] Stricture associated with primary tracheoesophageal puncture after pharyngolaryngectomy and free jejunal interpositionHEAD & NECK: JOURNAL FOR THE SCIENCES & SPECIALTIES OF THE HEAD AND NECK, Issue 3 2006Gurston G. Nyquist MD Abstract Background. Free jejunal interposition has been one of the standard reconstructive options for patients undergoing total laryngopharyngoesophagectomy. Tracheoesophageal puncture (TEP) done primarily is a well-accepted means of voice restoration. The rapid recovery of swallowing and communication in patients who have advanced cancer of the upper aerodigestive tract is a valid goal. The objective of this study was to evaluate the functionality and complications of primary TEP in patients with a free jejunal interposition graft. Methods. Twenty-four consecutive patients who had free jejunal interposition were studied. Thirteen of these patients had a primary TEP. Stricture was assessed through barium swallow, laryngoscopy, and CT scan. Results. A statistically significant greater number of patients had stricture develop after primary TEP (p < .0325). All these patients had stricture develop at the distal anastomosis. These patients also tended to have a poorer quality of diet. Moreover, speech with a TEP prosthesis in patients with a free jejunal interposition was less intelligible and functional than speech with a TEP prosthesis after simple laryngectomy. Conclusions. This article recognizes an increased incidence of stricture formation after primary TEP as compared with non-TEP in patients undergoing pharyngolaryngectomy with free jejunal interposition. The morbidity and possible etiology of this complication are discussed. This clinical data have been translated into a change in clinical practice. © 2005 Wiley Periodicals, Inc. Head Neck27: XXX,XXX, 2005 [source] Comparison of DNA Complex Formation Behaviour for Two Closely Related Lexitropsin AnaloguesHELVETICA CHIMICA ACTA, Issue 5 2009Abstract Two closely related lexitropsin analogues that differ only in the form of the ,headgroup' functionality (CHO (for 1) vs. Ac (for 2)) have been studied in their DNA-binding capacity for the sequence d(GCATATATGC) using 1H-NMR spectroscopy. DNA-Complex formation for the CHO derivative was apparent from the observation of new NMR signals on titration of DNA with ligand. Detailed investigation and assignment of the data for a ligand/DNA-duplex ratio of 2,:,1 clearly delineated the structure as one associated with the ,minor groove' class of DNA complexes. The structure of the complex was determined on the basis of the acquired NMR data. Features characteristic of typical 2,:,1 minor-groove complexes were apparent. In a similar experimental approach, the Ac analogue ligand,DNA binding response was investigated. Despite the close similarity in chemical structure to the CHO case, the Ac analogue was found to produce NMR data of a much poorer quality. This was attributed to more rapid on/off chemical exchange equilibrium between ligand and DNA. From close analysis and comparison of the NMR data for the ,Ac' and ,CHO' headgroup ligand,DNA complexes, it was possible to ascertain that the same type of complex formed in each case but with different relative binding constants. Consideration of the nature and form of these complexes has been made with reference to a previously determined structure from our laboratory for the related lexitropsin analogue thiazotropsin A. [source] Food consumption patterns, dietary quality and health status of expectant mothers: case studies in suburban and rural communities in GhanaINTERNATIONAL JOURNAL OF CONSUMER STUDIES, Issue 1 2002Christina A. Nti Abstract The study was conducted to determine the food consumption patterns, dietary quality and health status of expectant women and also to assess their level of awareness of nutritional requirements during pregnancy. Food beliefs, taboos and superstitions held by the women were also investigated. Using the purposive sampling technique, 30 pregnant women attending the Maternal and Child Health Clinic at Dodowa (rural) and University Hospital, Legon (suburban), were selected for the study. A structured questionnaire was used to collect information on the respondents' nutritional knowledge, beliefs, taboos and superstitions and health status. A food frequency questionnaire and the 24-h dietary recall method were used to obtain information on food consumption patterns and dietary quality. The study revealed that, although the majority of the respondents (83.3%) had some knowledge of nutrition, not all were applying it in their feeding practices because of financial constraints. With regard to consumption patterns, most of the women (83.3%) were having three meals a day, while the rest either ate twice a day or anytime they were hungry. Seventy-three per cent of the respondents also increased their food intake during pregnancy. Foods eaten were based mainly on starchy roots and tubers, cereals and vegetables. Legumes, oilseeds and fruits were often lacking in the main meals of respondents. Although animal products were consumed daily, the quantities taken were very small to provide for adequate protein, especially in the rural area. Various types of food were avoided by some of the expectant mothers for reasons such as nausea, loss of appetite, taboos and superstition. With regard to dietary quality, respondents from the rural area had diets of poorer quality in terms of nutrient intake compared with those from the suburban area. In both communities, iron contents of diets were quite low. Forty-seven per cent of the women interviewed were anaemic, with a higher prevalence of anaemia being observed in the rural community. Common ailments reported by the women were dizziness, headache, waist pains and malaria. Based on the results of the study, it was recommended that nutrition education for pregnant women should be stepped up at antenatal clinics especially in rural areas. [source] Quantification of dynamic mixing performance of single screws of different configurations by visualization and image analysisADVANCES IN POLYMER TECHNOLOGY, Issue 1 2009A. C.-Y. Abstract The visualization and image analysis techniques developed by the authors for the study of quantifying the dynamic quality of mixing of a single-screw extruder were employed to investigate the mixing performance of screws of different configurations. The mixing quality was quantified by calculating the variances of the light intensity of the bitmap files cropped from the films taken at the screw length of 15D and 17D of a 45-mm screw diameter single-screw extruder. Temperature and screw speed were the two variables studied. While temperature and back pressure were found to have little effect on the mixing quality, screw speed was demonstrated to be a major factor responsible for the mixing fluctuation observed during extrusion. In fact, screw speed and mixing fluctuation appeared to have a relationship that the higher the screw speed, the bigger the fluctuation (i.e., poorer quality of mixing). The experimental results also revealed that the secondary flight of a barrier screw might be essential to improve the quality of mixing. © 2009 Wiley Periodicals, Inc.

Irritable bowel syndrome has been classified to subgroups by predominant bowel symptom: constipation, diarrhoea or alternating between the two. Little is presently known about the specific impact of irritable bowel syndrome on health-related quality of life within disease sub-groups across time. Aims., To examine the health-related quality of life in a cohort of individuals with irritable bowel syndrome to explore the association between quality of life and disease subtype classification. Setting., The general population of the UK. Design., Longitudinal cohort survey was conducted. Methods., Individuals with symptoms of irritable bowel syndrome were recruited via a UK-wide newspaper advertisement. The health-related quality of life was measured using a battery of validated questionnaires. Results., Data on 494 participants with a Rome II confirmed diagnosis of irritable bowel syndrome were examined. Measurement of generic health-related quality of life revealed lower median scores (poorer quality of life) in anxiety/depression and pain/discomfort domains of health. Conclusion., Health-related quality of life is impaired in community based individuals with IBS. Patients appear to fluctuate between sub-groups when irritable bowel syndrome is classified across time. This study suggests that the impact of irritable bowel syndrome may be greatly underestimated. Relevance for clinical practice., The use of sub-group classification and understanding of predictive factors may allow for a more flexible and efficient approach to healthcare assessment and patient care for people with irritable bowel syndrome. [source] Evaluation of plastic packages for guava refrigerated preservationPACKAGING TECHNOLOGY AND SCIENCE, Issue 1 2001Angelo Pedro Jacomino Abstract Guavas cv. ,Kumagai' were packed in several plastic materials and stored at 10°C and 85,90% relative humidity (RH) for 7, 14, 21 and 28 days (+3 days at 25°C). The plastic materials studied were: multilayer co-extruded polyolephine film with selective permeability (PSP), low-density polyethylene film (LDPE), LDPE film with mineral incorporation (LDPEm) and heat-shrinkable polyolephine film (SHR). Guavas not packed were taken as control samples. The physicochemical characteristics of the fruits, O2 and CO2 transmission rates of the packaging materials and gas composition at the package headspace were evaluated. The LDPE film, 69,µm in thickness, with the lowest permeability to both O2 and CO2, led to anaerobiosis and high CO2 concentration inside the packages and promoted physiological disturbances and changes in fruit flavour. The SHR film, 15,µm in thickness, was the most permeable to CO2 and had quite high O2 transmission, which modified the inner atmosphere of the packages slightly. The fruits packed in this film showed a poorer quality than the controls, possibly due to the heat produced during the shrinking of the film. The LDPEm film, 24,µm in thickness, was almost as permeable to CO2 but had reduced O2 transmission, promoting an atmosphere of equilibrium of 3% O2 and 4.5% CO2. Fruits packed in this film kept their skin colour and pulp firmness, suitable for consumption up to 14 days. The PSP film, 35,µm in thickness, had the greatest O2 transmission but just over half of the CO2 transmission of LDPEm, promoting an atmosphere of equilibrium of 0.5% O2 and 4.5% CO2 inside the packages. Fruits packed in such packages kept their physicochemical characteristics up to 21 days. Copyright © 2001 John Wiley & Sons, Ltd. [source] Relationship of age to symptom severity, psychiatric comorbidity and health care utilization in persons with borderline personality disorderPERSONALITY AND MENTAL HEALTH, Issue 1 2008Nancee Blum Background,The objective of the study was to test the association of age with symptom severity, frequency and pattern of psychiatric comorbidity, health care utilization and quality of life in subjects with borderline personality disorder (BPD). Methods,The analysis is based on a sample of subjects with Diagnostic and Statistical Manual of Mental Disroders, Fourth Edition (DSM-IV) BPD (n = 163) recruited for participation in a clinical trial at an academic medical center. The subjects were assessed using structured and semi-structured instruments of known reliability. Results,Tests of trend with age showed relationships with important variables assessing symptom severity, comorbidity, quality of life and health care utilization. As expected, younger subjects were less likely to be married, to be employed or to receive disability payments. The frequency of most lifetime comorbid Axis I disorders was not related to age, although posttraumatic stress disorder was more frequent in the 35- to 44-year age group, and younger patients were more likely to have comorbid histrionic and narcissistic personality disorders. Baseline severity variables were mostly unrelated to age, with the exception of impulsivity, which was more common in younger patients, as were acts of deliberate self-harm. As expected, older patients reported poorer quality of life in categories indicating worse health perception and greater pain levels, and tended to use more health care resources than younger patients. Conclusion,Most characteristics of patients with BPD are unrelated to age, yet impulsivity and acts of deliberate self-harm were less frequent in older patients. Expected age-related changes, such as reports of worse physical health, greater pain levels and greater health care utilization, were observed in older subjects.

[source] Quality of life of patients with ovarian cancer in Taiwan: validation and application of the Taiwan Chinese version of the EORTC QLQ-OV28PSYCHO-ONCOLOGY, Issue 7 2010Wei-Chu Chie Abstract Objective: The aim of this study was to examine the reliability and validity of the Taiwan Chinese Version of the EORTC QLQ-OV28. Methods: The authors translated the questionnaire according to the guideline of the EORTC. A total of 96 patients with ovarian cancer in National Taiwan University Hospital were interviewed with the questionnaire and the EORTC QLQ-C30 between September 2004 and September 2007. Answer distribution and psychometric properties of the EORTC QLQ-OV28 were examined. Results: The mean age of the patients was 54 (standard deviation 12 years). Most of the patients were in FIGO stages III or IV. Two thirds were on-treatment (chemotherapy). Items for gastrointestinal (GI) symptoms, menopausal symptoms, and sexuality showed more flooring effects than others. Missing values were frequent in further questions about sexual activity. After excluding conditional questions, the Cronbach's alpha coefficients of most scales were satisfactory (0.74,0.89), except other chemotherapy side effects (0.63) and menopausal symptoms (0.39). The item-to-own and item-to-other scales correlation showed satisfactory results. Patients who were on-treatment had significantly poorer quality of life (QoL) scores in most symptom scales. Conclusions: The EORTC QLQ-OV28 is a valid instrument to assess QoL issues of patients with ovarian cancer in Taiwan, a country of a different culture. Copyright © 2009 John Wiley & Sons, Ltd. [source] Airway hyperresponsiveness: the usefulness of airway hyperresponsiveness testing in epidemiology, in diagnosing asthma and in the assessment of asthma severityTHE CLINICAL RESPIRATORY JOURNAL, Issue 1 2007Celeste Porsbjerg MD Abstract The present PhD thesis was conducted at the Respiratory Research Unit at the Pulmonary Department L in Bispebjerg Hospital, Copenhagen, Denmark and describes airway hyperresponsiveness in asthma patients in four studies. The first study concerned risk factors for the development of asthma in young adults in a 12-year prospective follow-up study of a random population sample of 291 children and adolescents from Copenhagen, who were followed up from the age of 7,17 years (1986) until the age of 19,29 years (1998). During follow-up, 16.1% developed asthma, and in these subjects, the most important predictor of asthma development was airway hyperresponsiveness to histamine at baseline. Airway hyperresponsiveness is associated with more severe asthma and a poorer prognosis in terms of more exacerbations and less chance of remission of the disease. The second study described the relation between airway hyper-responsiveness to methacholine and the quality of life in 691 asthma patients: In asthma patients with airway hyperresponsiveness to methacholine, the quality of life measured with a validated questionnaire (Junipers Asthma Quality of Life Questionnaire) was significantly reduced compared to asthma patients who did not respond to bronchial provocation with methacholine. Airway hyperresponsiveness is not uncommonly observed in non-asthmatics, and the response to bronchial provocation with methacholine is therefore relatively non-specific. The mannitol test is a relatively new bronchial provocation test that acts indirectly on the smooth airway muscle cells through the release of mediators from inflammatory cells in the airways; the mannitol could consequently be a more specific test compared with methacholine. The third study showed that out of 16 non-asthmatics with airway hyperresponsiveness to methacholine, 15 did not respond to bronchial provocation with mannitol Because of the mechanism of action of mannitol, it seems plausible that the response to mannitol is more closely correlated to airway inflammation in asthma compared with the response to methacholine. The fourth study showed that in 53 adult asthma patients, who did not receive treatment with inhaled steroids, there was a positive correlation between the degree of airway inflammation and the degree of airway responsiveness to mannitol as well as to methacholine. The mannitol does, however, have the advantage of being a faster and simpler test to perform, requiring no additional equipment apart from a spirometer. Conclusions:, Airway hyperresponsiveness in children and in adolescents without asthma predicts asthma development in adulthood. Asthma patients with airway hyperresponsiveness to methacholine have a poorer quality of life as well as more severe disease and a poorer prognosis compared with asthma patients without airway hyperresponsiveness. Bronchial provocation with mannitol as well as with methacholine were useful for evaluating the severity of asthma and the degree of airway inflammation, and accordingly for determining the need for steroid statement. The mannitol test does, however, have practical advantages over the methacholine test that make it preferable for clinical use. [source] Artificial spawning of European catfish Silurus glanis L.: differences between propagation results after stimulation of ovulation with carp pituitary and OvopelAQUACULTURE RESEARCH, Issue 1 2001E Brzuska Abstract The effect of spawning on European catfish females with an average body weight of 5.6 kg and 11.2 kg was investigated, with carp pituitary and Ovopel being used as ovulation stimulators. Ovopel induced ovulation in a higher percentage of females of both smaller and larger body weight. The applied ovulation stimulators did not significantly affect the weight of the obtained eggs. On the other hand, the effect of the stimulators was highly significant (P,,0.01) with respect to the percentage of live embryos after 24-, 48- and 56-h incubation. The fish of greater body weight yielded eggs of a significantly (P,,0.05) greater weight, although of poorer quality. The interaction between the ovulation stimulator and female body weight was statistically significant (P,,0.05) for the weight of the obtained eggs and highly significant (P,,0.01) for the percentage of live embryos after 48-h incubation. For the percentage of live embryos after 24- and 56-h incubation, the statistical significance (P,,0.05) of this interaction was determined. In the case of females of smaller body weight, a statistically significant (P,,0.05) phenotypic correlation was found between the percentage of live embryos after 24-h incubation and that after 48-h incubation, and also between the percentage of live embryos after 24- and 56-h incubation. [source] Association between painful physical symptoms and clinical outcomes in Taiwanese patients with major depressive disorder: A three-month observational studyASIA-PACIFIC PSYCHIATRY, Issue 3 2010Kuang-Peng Chen MD Abstract Introduction: Reports from non-Asian populations indicate that painful physical symptoms are associated with poorer clinical and functional outcomes in patients with Major Depressive Disorder (MDD). This paper shows the changes in disease characteristics and quality of life in Taiwanese MDD patients, with or without painful physical symptoms, over 3 months' observation. Methods: Taiwanese patients from an observational study of six East Asian countries/regions were classified as painful physical symptom positive (PPS+) or negative (PPS,) based on a mean score of ,2 or <2, respectively, on the modified Somatic Symptom Inventory. Changes from baseline in outcomes were compared between the groups. Results: Of 194 patients with MDD, 69% were PPS+ at baseline. These PPS+ patients were more depressed (17-item Hamilton Depression Rating Scale total; mean [SD] 27.1 [6.26] versus 21.8 [5.94] PPS,, P<0.001), in more pain (Visual Analog Scale overall; median [range] 73.5 [9,100] versus 40 [0 to 80] PPS,, P<0.001) and had poorer quality of life at baseline (EuroQoL; mean [SD] 42.9 [18.26] versus 59.8 [18.21] PPS,,P<0.001). At endpoint (n=118), PPS, patients showed greater improvement on depression outcomes (Clinical Global Impression of Severity; P=0.011) and had a higher remission rate (52.8 % versus 14.6% PPS+, P=0.007). Discussion: Painful physical symptoms were frequently observed in Taiwanese patients with MDD. As PPS are associated with more severe depression, poorer quality of life, and poorer remission outcomes, clinical management should address both the mental and physical symptoms associated with this disorder. [source] Prevalence of depression and anxiety in hospitalized chronic obstructive pulmonary disease patients and their quality of life: a pilot studyASIA-PACIFIC PSYCHIATRY, Issue 3 2009Herng Nieng Chan MBBS MMed (Psychiatry) Abstract Introduction: There is a high prevalence of psychiatric comorbidities in patients with Chronic Obstructive Pulmonary Disease (COPD). It has been reported that if left untreated, the psychiatric comobidities can lead to poorer quality of life. The present study was initiated to investigate the prevalence of major depressive disorder, generalized anxiety disorder and panic disorder in hospitalized COPD patients and their quality of life. Methods: The Patient Health Questionnaire (PHQ) of the Primary Care Evaluation of Mental Disorders (PRIME-MD) was administered to screen an opportunistic sample of COPD patients admitted to a general hospital for the abovementioned psychiatric disorders. The Medical Outcomes Study (MOS) 36-Item Short Form Health Survey (SF-36) was utilized to assess quality of life. Results: Fifty-one patients were analyzed. The prevalence of major depressive disorder in this sample on screening was 7.8% (95% CI 2.2,18.9) and that of anxiety disorders (generalized anxiety disorder and panic disorder) was 5.9% (95% CI 1.2,16.2). The quality of life of COPD patients with psychiatric comorbidities in the present study was severely impaired in seven of the eight domains measured by the SF-36. Discussion: Despite the small sample size of COPD patients, the prevalence of psychiatric comorbidities was not insignificant. The present study showed that the quality of life of hospitalized COPD patients with psychiatric illnesses was significantly lowered. Treatment of COPD should include addressing psychosocial issues.

Results are presented on 112 persons with an ICD-10 diagnosis of bipolar disorder. Results:, Overall, 69.6% of the 112 persons who met the ICD-10 criteria for bipolar disorder reported a recurrent episodic illness, 25.0% had a chronic course without clear remissions, and 5.4% had a single episode of mania. Assessed on a lifetime basis, suicidal ideation was common (78.6%) and levels of drug and alcohol abuse/dependence were high (32.1%). The majority (84.8%) had had at least one contact with inpatient, outpatient or emergency services in the previous year. Those with serious impairment had levels of service utilization similar to the rest of the sample, but were more likely to report a poorer quality of life and unmet service needs. While the percentage experiencing social and occupational dysfunction was substantial and similar for both sexes, women appeared to be better integrated socially than men. Comparisons with schizophrenia patients within the same survey sample highlighted less chronic impairment but equal or greater utilization of services by bipolar patients. Conclusions:, Despite low levels of chronicity, the burden of social disablement associated with bipolar disorder is high. The data suggest a number of important gaps in the provision of services for this predominantly treated population.

Nguyen Study Objective,,, Nested case-control study aimed to assess the quality of life of community dwelling participants aged 65 years or over with newly diagnosed Essential Tremor (ET). Methods and Results,,, Thirty-two participants with newly diagnosed ET and 32 age and gender matched controls were administered the Rand-SF36 quality of life questionnaire. Medical co-morbidities were also assessed in the two groups. Results,,, Participants with ET had significantly lower scores in the physical function, role limitation because of physical function, role limitation as a result of emotional problem, pain, and energy/vitality subscales of the Rand-SF36 when compared with controls. Conclusions,,, Older patients with newly diagnosed ET have poorer quality of life than their community dwelling counterparts without ET. [source] The impact of age at onset of bipolar I disorder on functioning and clinical presentationACTA NEUROPSYCHIATRICA, Issue 4 2009Frances Biffin Objectives: Recent studies have proposed the existence of three distinct subgroups of bipolar 1 disorder based on age at onset (AAO). The present study aims to investigate potential clinical and functional differences between these subgroups in an Australian sample. Methods: Participants (n = 239) were enrolled in the Bipolar Comprehensive Outcomes Study (BCOS), a 2-year longitudinal, observational, cross-sectional study. Assessment measures included the Young Mania Rating Scale (YMRS), Hamilton Depression Rating Scale (HAMD21), Clinical Global Impressions Scale (CGI-BP), SF-36, SLICE/Life Scale, and the EuroQol (EQ-5D). Participants were also asked about their age at the first major affective episode. Results: Three AAO groups were compared: early (AAO < 20, mean = 15.5 ± 2.72; 44.4% of the participants); intermediate (AAO 20,39, mean = 26.1 ± 4.8; 48.14% of the participants) and late (AAO > 40, mean = 50.6 ± 9.04; 7.4% of the participants). Higher rates of depression, suicidal ideation and binge drinking were reported by the early AAO group. This group also reported poorer quality of life in a number of areas. The early AAO group had a predominant depressive initial polarity and the intermediate group had a manic predominance. Conclusion: Early AAO is associated with an adverse outcome. [source] Language, Social Behavior, and the Quality of Friendships in Adolescents With and Without a History of Specific Language ImpairmentCHILD DEVELOPMENT, Issue 5 2007Kevin Durkin Language is drawn on extensively in friendships but has received scant attention in the developmental literature. This study compared friendship quality in 16-year-old adolescents with and without specific language impairment (SLI), testing the extent it is predicted by individual differences in social behaviors and language ability. Participants were 120 adolescents with SLI and 118 typically developing (TD) adolescents. After considering the effects of nonverbal IQ and prosocial and difficult behavior, language measures were found to be associated with friendship quality. The TD participants enjoyed normal friendships, whereas the participants with SLI were more likely to exhibit poorer quality (although 60% experienced good quality of friendships). Longitudinal analyses identified early language difficulties as predictive of poorer friendship quality in adolescence. [source] Cultural perspectives of interventions for managing diabetes and asthma in children and adolescents from ethnic minority groupsCHILD: CARE, HEALTH AND DEVELOPMENT, Issue 5 2010V. Mc Manus Abstract Both diabetes and asthma are increasingly being recognized as health problems for ethnic groups. Because of cultural differences, ethnicity is reported to be a risk factor for poorer quality in health care, disease management and disease control. Ethnic groups are at risk for poorer quality of life and increased disease complications when compared with non-ethnic counterparts living in the same country. There is little known about how culture is addressed in interventions developed for ethnic groups. The aim of this paper is to systematically review the cultural perspectives of interventions for managing diabetes and asthma in children, adolescents and/or their families from ethnic minority groups. A total of 92 records were identified that were potentially relevant to this review following which, 61 papers were excluded. The full texts of remaining papers (n= 31) were then read independently by both authors, and agreement was reached to exclude a further 27 papers that did not meet inclusion criteria. A total of four papers were eligible for inclusion in this review. Findings indicate that despite growing concerns about health disparities between ethnic and non-ethnic groups in relation to both asthma and diabetes in childhood, there has been little effort to develop cultural specific interventions for ethnic groups. By systematically reviewing asthma and diabetes interventions we have highlighted that few interventions have been developed from a cultural perspective. There are a limited number of interventions published that add knowledge on the specific elements of intervention that is needed to effectively and sensitively educate other cultures. More work is required into identifying which strategies or components of cultural interventions are most effective in achieving positive health outcomes for children, adolescents and/or their families from ethnic groups. [source] Symptom experience associated with immunosuppressive drugs after liver transplantation in adults: possible relationship with medication non-compliance?CLINICAL TRANSPLANTATION, Issue 6 2008G. Drent Abstract:, Symptom experience (occurrence and perceived distress) associated with side effects of immunosuppressive medications in organ transplant patients may well be associated with poorer quality of life and medication non-compliance. The aims of this study were: first, to assess symptom experience in clinically stable adult patients during long-term follow-up after liver transplantation; and second, to study the relationship between symptom experience and medication non-compliance. This cross-sectional study included 123 liver transplant patients. Symptom experience was assessed using the "Modified Transplant Symptom Occurrence and Symptom Distress Scale" (29-item version) at the annual evaluation. According to the duration of follow-up, patients were divided into a short-term (1,4 yr) and a long-term (5,18 yr) cohort. Medication non-compliance was measured using electronic monitoring. Results showed that increased hair growth was the most frequent symptom in both sexes. Symptom distress was more serious in women than in men. The most distressing symptom in women was excessive and/or painful periods, while in men this was impotence. Clear differences were revealed at item level between symptom occurrence and symptom distress in relationship with the two time cohorts and between sexes. No relationship was found between symptom experience and prednisolone non-compliance. [source] | |||||||||||||||||||||||||||||||
