Abstract
OBJECTIVE The objective of this paper is to assess overactive bladder (OAB) symptom bother (SB) and health-related quality of life (HRQL) among patients with systemic lupus erythematosus (SLE) and primary Sjögren syndrome (pSS). METHODS We recruited adult SLE and pSS patients and two groups of age- and sex-matched controls. We applied the OAB questionnaire-short form (OABq-SF) to all participants to assess SB and HRQL and collected clinical information relevant for OAB. We compared the OABq-SF scores for SB and HRQL between patients and controls using univariate and multivariate linear regression analysis. RESULTS We recruited 95 rheumatic patients (68 SLE, 27 pSS) and 231 controls. Compared to controls SLE patients showed higher OABq-SF SB scores (22.6 ± 20.4 vs 14.7 ± 17.0, p = 0.004) and lower HRQL scores (89.8 ± 15.8 vs 93.8 ± 11.4, p = 0.044). On multivariate analysis SLE was significantly associated with a higher SB score (ß-coefficient 7.13, p = 0.008) and tended to be associated with worse HRQL values (ß-coefficient -3.53, p = 0.055). Patients with pSS had numerically higher mean SB scores (22.8 ± 22.5 vs 16.2 ± 18.0, respectively, p = 0.107) and lower HRQL scores (91.0 ± 10.7 vs 93.2 ± 11.6, respectively, p = 0.369), although these differences were not statistically significant. Diagnosis of pSS was not significantly associated with SB or HRQL scores on univariate or multivariate analysis. CONCLUSIONS Patients with SLE have significantly worse OAB-SB and poorer HRQL compared to controls. A similar trend was seen for pSS patients, especially for SB. These findings suggest that clinically subtle OAB symptoms may be present in rheumatic patients for whom, later on, bladder pain syndrome may occur.

Attitudes of health care professionals toward people with intellectual disability: a comparison with the general population. JOURNAL OF INTELLECTUAL DISABILITY RESEARCH : JIDR 2018; 62:746-758. [PMID: 29968307 DOI: 10.1111/jir.12510] [Citation(s) in RCA: 20] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/18/2017] [Revised: 04/03/2018] [Accepted: 06/07/2018] [Indexed: 06/08/2023]
Abstract
BACKGROUND Few studies have examined attitudes that may promote the social inclusion of persons with an intellectual disability (ID) among health care providers (HCPs). Yet these attitudes could impact the accessibility and quality of services provided to this population, as well as the general attitudes of HCPs. The objectives of this study were to (1) examine HCPs' pro-inclusion attitudes toward people with ID, (2) compare these to the general population's attitudes and (3) examine how HCPs' attitudes vary as a function of their socio-demographic characteristics. METHOD The Attitudes Toward Intellectual Disability Questionnaire was administered to 367 HCPs and a representative sample of the Québec population (N = 1605). RESULTS Results indicated that at least half of HCPs displayed positive attitudes, that is, attitudes that are compatible with notions of social inclusion and equal rights, toward individuals with ID. Positive attitudes were less frequently observed for the Interaction and the Sensitivity or tenderness factors measured by the Attitudes Toward Intellectual Disability Questionnaire. In comparison with the general population, HCPs exhibited more positive attitudes on the Knowledge of causes and Sensitivity or tenderness factors and less positive attitudes on the Interaction factor. HCPs who regarded themselves as more knowledgeable about ID and those who reported higher quality contacts or interactions with persons with ID expressed attitudes that were more favourable toward social inclusion. CONCLUSIONS In addition to providing general knowledge about ID and the specific health care needs of individuals with ID, training programmes should also promote interactions with this population. Further studies are needed to document HCPs' pro-inclusion attitudes toward people with ID and to assess the impact of interventions on these attitudes.

Abstract
BACKGROUND The international standard of care for women with suspected advanced ovarian cancer is surgical debulking followed by platinum-based chemotherapy. We aimed to establish whether use of platinum-based primary chemotherapy followed by delayed surgery was an effective and safe alternative treatment regimen. METHODS In this phase 3, non-inferiority, randomised, controlled trial (CHORUS) undertaken in 87 hospitals in the UK and New Zealand, we enrolled women with suspected stage III or IV ovarian cancer. We randomly assigned women (1:1) either to undergo primary surgery followed by six cycles of chemotherapy, or to three cycles of primary chemotherapy, then surgery, followed by three more cycles of completion chemotherapy. Each 3-week cycle consisted of carboplatin AUC5 or AUC6 plus paclitaxel 175 mg/m(2), or an alternative carboplatin combination regimen, or carboplatin monotherapy. We did the random assignment by use of a minimisation method with a random element, and stratified participants according to the randomising centre, largest radiological tumour size, clinical stage, and prespecified chemotherapy regimen. Patients and investigators were not masked to group assignment. The primary outcome measure was overall survival. Primary analyses were done in the intention-to-treat population. To establish non-inferiority, the upper bound of a one-sided 90% CI for the hazard ratio (HR) had to be less than 1.18. This trial is registered, number ISRCTN74802813, and is closed to new participants. FINDINGS Between March 1, 2004, and Aug 30, 2010, we randomly assigned 552 women to treatment. Of the 550 women who were eligible, 276 were assigned to primary surgery and 274 to primary chemotherapy. All were included in the intention-to-treat analysis; 251 assigned to primary surgery and 253 to primary chemotherapy were included in the per-protocol analysis. As of May 31, 2014, 451 deaths had occurred: 231 in the primary-surgery group versus 220 in the primary-chemotherapy group. Median overall survival was 22.6 months in the primary-surgery group versus 24.1 months in primary chemotherapy. The HR for death was 0.87 in favour of primary chemotherapy, with the upper bound of the one-sided 90% CI 0.98 (95% CI 0.72-1.05). Grade 3 or 4 postoperative adverse events and deaths within 28 days after surgery were more common in the primary-surgery group than in the primary-chemotherapy group (60 [24%] of 252 women vs 30 [14%] of 209, p=0.0007, and 14 women [6%] vs 1 woman [<1%], p=0.001). The most common grade 3 or 4 postoperative adverse event was haemorrhage in both groups (8 women [3%] in the primary-surgery group vs 14 [6%] in the primary-chemotherapy group). 110 (49%) of 225 women receiving primary surgery and 102 (40%) of 253 receiving primary chemotherapy had a grade 3 or 4 chemotherapy related toxic effect (p=0.0654), mostly uncomplicated neutropenia (20% and 16%, respectively). One fatal toxic effect, neutropenic sepsis, occurred in the primary-chemotherapy group. INTERPRETATION In women with stage III or IV ovarian cancer, survival with primary chemotherapy is non-inferior to primary surgery. In this study population, giving primary chemotherapy before surgery is an acceptable standard of care for women with advanced ovarian cancer.

Associations of wheat with pea can reduce aphid infestations. NEOTROPICAL ENTOMOLOGY 2015; 44:286-93.

Abstract
Increasing plant diversity within crops can be beneficial for pest control. In this field study, the effects of two wheat and pea associations (mixed cropping and strip cropping) on aphid populations were compared with pure stands of both crops by observations on tillers and plants. Pea was more susceptible to infestations than wheat. As expected, the density of aphid colonies was significantly higher in pure stands during the main occurrence periods, compared with associations. Additionally, flying beneficials, such as not only aphidophagous adult ladybirds but also parasitoid, hoverfly and lacewing species that feed on aphids at the larval stage, were monitored using yellow pan traps. At specific times of the sampling season, ladybirds and hoverflies were significantly more abundant in the pure stand of pea and wheat, respectively, compared with associations. Few parasitoids and lacewings were trapped. This study showed that increasing plant diversity within crops by associating cultivated species can reduce aphid infestations, since host plants are more difficult to locate. However, additional methods are needed to attract more efficiently adult beneficials into wheat and pea associations.

Abstract
5500 Background: First line treatment of advanced ovarian cancer (OC) is accepted to be primary surgery (PS) followed by adjuvant platinum-based chemotherapy (P-CT). However, the EORTC55971 trial suggested neoadjuvant chemotherapy (NACT) is an alternative, showing increased optimal debulking rates and reduced surgical complications without detriment to survival. CHORUS (CRUK 07/009) is the 2nd phase III randomized controlled trial to investigate timing of initial surgery in OC. Methods: Patients (pts) with clinical FIGO stage III-IV OC (pelvic mass, extrapelvic metastases and CA125/CEA ratio >25) were randomized to standard treatment (PS followed by 6 cycles P-CT) or NACT (3 cycles P-CT either side of surgery). CHORUS was designed to demonstrate non-inferiority of NACT, excluding a 6% absolute detriment in 3yr survival from 50% expected with PS (1-sided alpha 10%). Primary outcome was overall survival (OS) and secondary outcomes were progression free survival (PFS), toxicity and quality of life. Results: 550 women (276 PS, 274 NACT) were randomized from 74 centres (72 UK, 2 NZ) between Mar 2004 and Aug 2010. Baseline characteristics were well balanced: median age 65yrs, median tumor size 80mm, 25% FIGO stage IV, 19% WHO PS 2. Median follow-up was 3yrs, 410 pts have died. Treatment data are summarized in the Table. 3yr survival in the control arm was 32%. Intention to treat analysis showed a median OS of 22.8 months for PS vs 24.5 months for NACT (hazard ratio (HR) 0.87 in favor of NACT, 80% CI 0.76 – 0.98) and median PFS of 10.2 vs 11.7 months (HR 0.91, 0.81 – 1.02). OS results represent a 5% absolute benefit in 3yr survival for NACT to 37% and the upper 80% CI allows us to exclude a survival benefit for PS. Conclusions: NACT was associated with increased optimal debulking, less early mortality and similar survival in this poor prognosis group. CHORUS results are consistent with EORTC55971 and strengthen evidence that NACT is a viable alternative to PS. Clinical trial information: ISRCTN74802813. [Table: see text]

Abstract
INTRODUCTION The Pulmonology Service of a Central Hospital in Lisbon created a Unit dedicated to the treatment of tuberculosis (TB). OBJECTIVES Casuistic analysis and assessment of the predictive factors for in-hospital mortality, over a 10-years period. MATERIAL/METHODS Retrospective study, from April 1999 to September 2009, through the Statistical Package for the Social Sciences application for binary logistic regression. RESULTS In a total of 1917 patients, most were male (n=1450; 76%), Caucasian (76.6%), with an average age of 43±15.2 years, and 19.8% were immigrants. The retreatments were responsible for 26% of the hospitalizations. The presence of comorbidities was detected in 85.7%, particularly HIV infection (34.7%). The multidrug-resistant (MDR) and the extensively drug resistant (XDR) TB occurred in 6.6% and 6.8%, respectively. The average delay was 28.5±54.8 days, with the mortality rate at 8.6%. The mortality risk was more significant amongst men (OR 1.8; 95%CI 1.16-2.90; p<0.01), in patients with HIV infection (OR 3.7; 95%CI 2.47-5.49; p<0.001), and amongst those who presented MDR TB (OR 2.5; 95%CI 1.24-5.15; p<0.01) and XDR TB (OR 5.5; 95%CI 3.14-9.58; p<0.001). CONCLUSIONS A high percentage of patients presented comorbidities, namely HIV infection. The main factors associated with mortality were HIV infection, XDR TB and MDR TB.

Abstract
Metastasis to the uterine corpus is uncommon and secondary colorectal tumours of the endometrium are rare. We describe a uterine tumour with components of both primary endometrial and metastatic colorectal carcinomata. In this case, a 72-year-old obese woman presented with a 2-week history of postmenopausal bleeding per vaginum and weight loss. She had an abdominoperineal resection 3 years previously for a Dukes stage B rectal carcinoma. A transvaginal ultrasonography showed a thickened endometrium. Histology immunophenotyping showed a CK7+, CK20+, CA125- and CEA+ colorectal metastasis (a profile consistent with her previous cancer) associated with a primary CK7+, CK20-, CA125+ and CEA- endometroid endometrial adenocarcinoma. We conclude this represents endometrial metastasis of colorectal carcinoma with coincident primary endometrial adenocarcinoma. We speculate as to whether the endometrial carcinoma arose de novo or was induced by the colorectal metastasis, or whether the primary endometrial tumour provided a fertile site for the colorectal metastasis.

Abstract
Cadmium (Cd) is a cytotoxic, mutagenic and carcinogenic metal. Mutagenesis is indicative of genetic instability and can be assayed by use of microsatellite markers (simple sequence repeats, SSRs). These are tandem-repeated tracts of DNA composed of units that are 1-6 base pairs (bp) long, spread throughout the genome and highly polymorphic. SSRs can be used in the detection of genomic DNA damage and/or mutational events (e.g. deletions, insertions, point mutations). In order to study chronic exposure to cadmium, Lactuca sativa L. seeds were germinated in distilled water and grown on modified Hoagland's medium, both supplemented with 0, 10 and 100microM Cd(NO(3))(2). After 28 days of exposure, the plants were harvested to assess shoot and root length and accumulation of cadmium. DNA was extracted from young and expanded leaves and roots in order to analyse microsatellite instability (MSI). Mutagenic effects of cadmium were evaluated on nine microsatellite loci. No MSI was found in leaves, but a 2-bp deletion in one lettuce root SSR was detected among the SSRs that were analysed. Thus, SSR analyses may provide a complementary tool in the assessment of different genotoxic effects of compounds on plants.

Abstract
Flow cytometry analyses were used to verify the ploidy stability of Quercus suber L. somatic embryogenesis process. Leaf explants of two adult cork oak trees (QsG0 and QsG5) of the North of Portugal were inoculated on MS medium with 2,4-D and zeatin. After 3 months, calluses with embryogenic structures were isolated and transferred to fresh MS medium without growth regulators and somatic embryo evolution was followed. Morphologically normal somatic embryos (with two cotyledons) and abnormal somatic embryos (with one or three cotyledons) were used in this assay. Flow cytometry combined with propidium iodide staining was employed to estimate DNA ploidy levels and nuclear DNA content of somatic embryos and leaves from mother plants. No significant differences (P< or =0.05) were detected among embryos, and between the embryos and the mother plants. Also, after conversion of these embryos, no significant morphological differences were observed among the somatic embryo-derived plants. These results and further studies using converted plantlet leaves and embryogenic callus tissue indicate that embryo cultures and converted plantlets were stable with regard to ploidy level. As no major somaclonal variation was detected our primary goal of "true-to-type" propagation of cork oak using somatic embryogenesis was assured at this level. The estimation of the 2C nuclear DNA content for this species is similar to the previously obtained value.

Abstract
Flow cytometry was used to measure the nuclear DNA content of Eucalyptus globulus Labill. somatic and zygotic embryos and leaves in order to determine if somatic embryogenesis induces DNA content and ploidy changes in this species. Mature zygotic embryos derived from open-pollination orchard families were collected from a location in the centre of Portugal. One group was kept for nuclear DNA content and ploidy analysis, and the other group was used for establishing embryogenic cultures. Mature zygotic embryos were grown on Murashige and Skoog (MS) medium supplemented with 3% (w/v) sucrose and 3 mg l(-1) alpha-naphthaleneacetic acid (NAA) for 3 weeks and then transferred to MS medium without growth regulators. Globular somatic embryos from approximately 8-month-old embryogenic cultures were used in the assay. DNA ploidy levels and the nuclear DNA content of mature zygotic embryos, somatic embryos and leaves from the mother field tree were determined using flow cytometry combined with propidium iodide staining. Zygotic embryos had a nuclear DNA content of 1.32 pg/2C, somatic embryos had a nuclear DNA content of 1.39 pg/2C and leaves from the field tree had a nuclear DNA content of 1.40 pg/2C. The values estimated for the somatic embryos and mother plant did not differ statistically from each other (P < or = 0.05), but both differed from those of the zygotic embryos (P < or = 0.05). These results clearly indicate that no changes were induced during the embryogenic process. However, the differences found between the field plants and zygotic embryos did suggest that some aspects must be evaluated carefully, as propidium iodide fluorescence may potentially be influenced by the presence of secondary compounds (e.g. anthocyanins, tannins) in E. globulus somatic embryos and mature leaves. Therefore we believe that the somatic embryogenesis methodology used did not induce major genetic changes in the somatic embryos and that our primary goal of "true-to-type" propagation was assured.

Abstract
An observational descriptive transversal study was carried out to analyse the clinical log-books of the patients with dyspeptic complaints in the General Practice consultation of Fernão de Magalhães Heath Center, during 1994. The aim of the study was to assess: the distribution of dyspeptic categories; the association of dyspepsia groups and the selected variables; the identified risk factors; the clinical investigation and its relationship with the age groups, as well as prescription in the General Practice consultations. The results of the study show that: functional dyspepsia is more frequent than organic; females have functional dyspepsia more frequently, with a statistically significant difference; there are more consultations with dyspeptic complaints among the elderly; about 50% of the patients with dyspeptic symptoms were investigated and two thirds were above forty-five years of age; the prescribed medication was similar to that recommended.

Abstract
OBJECTIVES To assess the efficacy of desmopressin nasal spray compared with diclofenac given intramuscularly in patients with acute renal colic caused by urolithiasis. PATIENTS AND METHODS The study included 61 patients randomized into three different groups; group A received desmopressin (40 microg, nasal spray), group B diclofenac (75 mg) intramuscularly and group C, both desmopressin and diclofenac. Pain was assessed using a visual analogue scale (a 10-cm horizontal scale ranging from 'no pain' to 'unbearable pain') at baseline, 10, 20 and 30 min after administering the treatments. RESULTS On admission, the pain level was the same in all three groups. At 10 min the pain decreased in all groups to a level that was not significantly different. At 20 min groups B and C had similar mean pain levels (3.7), whereas in group A it was 5.0. At 30 min, groups B and C scored 2-3, and group A 5.6. All three treatments were equally effective at 10 and 20 min but at 30 min there was a stabilization/slight increase in pain level in group A. CONCLUSIONS Desmopressin has several advantages, e.g. ease of administration, simplicity of delivery and apparent lack of side-effects, which makes it suitable for ambulatory use. Desmopressin acts rapidly and seems to be effective in both single and combined therapy with diclofenac; it decreases the need for a second treatment and increases the analgesic effect of diclofenac. Some patients responded well to desmopressin, with rapid and complete pain relief. These results indicate that desmopressin may be used to treat renal colic either alone or combined, increasing the analgesic effect of other drugs. More studies are needed to validate and confirm the results; it would also be useful to determine factors that may identify the subgroup of patients who respond quickly and with almost complete pain relief.

Abstract
OBJECTIVE To assess the place of laparoscopically assisted vaginal hysterectomy in the treatment of endometrial cancer. DESIGN A retrospective uncontrolled case series. SETTING Gynaecological Oncology Department, Queen Elizabeth Hospital, Gateshead. POPULATION Women with endometrial cancer referred to this centre from August 1992 to August 1997. MAIN OUTCOME MEASURES Success of laparoscopically assisted vaginal hysterectomy, operative morbidity, and the length of hospital stay. RESULTS Laparoscopically assisted vaginal hysterectomy was successful in 35 of 40 women (88%). Five women required laparotomy. Two women sustained injury to the inferior epigastric vessels. One sustained injury to the small intestine requiring later laparotomy and three women required a blood transfusion. The mean hospital stay was 3 x 3 days (SD 1 x 5). Three women died of the disease within one year of their operation. CONCLUSION Laparoscopically assisted vaginal hysterectomy is a feasible treatment for endometrial cancer. It can be performed successfully in high risk population who are medically unfit and overweight. However, a larger randomised study is required to assess the morbidity compared with the traditional open approach.

Abstract
PURPOSE The reconstruction of severe acetabular defects, caused by failed hip prostheses, is difficult and complex. Current radiographic descriptions of the defects are inadequate. We sought to more accurately describe remaining bone and improve surgical planning using 3D physical models based on CT data. METHOD Nineteen patients (20 hips) with failed total hip replacements and severe acetabular defects were selected. Plain radiography and CT were performed. Solid 3D physical models of each pelvis were constructed using the CT data. Bone loss in structurally important regions was measured from radiographs, models, and intraoperative observation. Comparisons were made of the radiograph-based and model-based bone loss measurements, surgical plans, and interobserver variability. RESULTS There was no statistical difference between the model-based measurements and the intraoperative measurements. Radiographs statistically underestimated bone loss by at least 20% (p < 0.01). Interobserver bone loss grading was poor for the radiograph-based measurements (kappa = 0.06) but was substantial for the model-based measurements (kappa = 0.73). In only half the cases was prosthesis type correctly selected based on radiographs. Model-based planning selected the correct prosthesis type in all cases. CONCLUSION The physical models were substantially more accurate than radiographs for measuring acetabular defects and for surgical planning.

Abstract
The Porsolt swim test (PST) was used to assess behavioral effects following acute or chronic treatment with two N-methyl-D-aspartate (NMDA) glycine partial agonists, 1-aminocyclopropanecarboxylic acid (ACPC), and D-cycloserine (DCS). Consistent with previous findings in mice, single intravenous doses of ACPC in rats produced a significant, dose-dependent reduction in immobility in the PST compared to saline. Single dose DCS also elicited significant dose-dependent reductions in PST immobility times. Single-dose ACPC or DCS (200 mg/kg) reduced immobility (p < 0.05) by 26 or 30%, respectively, compared to saline. However, multiple dosing with either ACPC or DCS (6 daily doses, 200 mg/kg) produced an apparent behavioral adaptation, as the immobility data were indistinguishable from chronic saline administration. Moreover, pretreatment with a 5-day course of ACPC or DCS promoted the development of a behavioral cross-tolerance following a sixth dose of DCS or ACPC, respectively. The development of a behavioral tolerance in the PST following chronic therapy of these drugs appears to be a general feature of glycine partial agonists. In toto, these findings support the hypothesis that chronic administration of NMDA glycine partial agonists produces a behavioral tolerance putatively through an adaptation of the NMDA receptor complex.

Abstract
Immunochemical reactivities of type A botulinum neurotoxin to polyclonal antibodies raised against the neurotoxin complex toxoid have been investigated using enzyme-linked immunosorbent assay (ELISA) and with a fiberoptic immunosensor. The complex contains a group of complexing proteins in addition to the neurotoxin itself. Neurotoxin specific immunoglobulin G (IgG), purified from the IgG raised against the complex using an affinity column, showed a two-fold increase in reactivity with purified neurotoxin compared to the neurotoxin in the complex. Antibodies against the whole complex reacted approximately five times better with the complex than with the neurotoxin, suggesting that the detection of the neurotoxin complex may be more sensitive. Considering the fact that the amount of the complexing proteins and neurotoxin appears to be in a 4:1 ratio, a five-fold higher reactivity could suggest a 25-fold higher detectability of the neurotoxin in the complex. ELISA binding curves of complexing proteins and purified neurotoxin with antibodies raised against the whole complex indicated the complexing proteins to have significantly higher antigenicity. Furthermore, IgG fraction with or without the neurotoxin specific antibodies reacted almost equally to the neurotoxin complex, again suggesting higher immunogenicity of the complexing proteins. Increased binding of the complexing proteins versus the purified neurotoxin to antibodies against the complex and thus immunogenicity was also observed in the binding curves generated using a fiberoptic immunosensor.

Abstract
The separations of peptide and protein mixtures in capillary zone electrophoresis (CZE) at various solution conditions were studied with the direct control of electroosmosis. The zeta potential at the aqueous/capillary interface and the resulted electroosmosis in the presence of an electric field were directly controlled by using an additional electric field applied from outside of the capillary. The controlled electroosmotic flow affected the migration time and zone resolution of peptide and protein mixtures. The changes in the magnitude and polarity of the zeta potential caused the various degrees of peptide and protein adsorption onto the capillary through the electrostatic interactions. The separation efficiencies of peptide and protein mixtures were enhanced due to the reduction in peptide and protein adsorption at the capillary wall. The direct manipulations of the separation efficiency and resolution of peptide and protein mixtures in CZE were demonstrated by simply controlling the zeta potential and the electroosmotic flow with the application of an external electric field.
