Bothersome symptoms at midlife in relation to body fat percentage.

OBJECTIVES: Increasing obesity has been associated with a higher frequency of symptoms at midlife. Bothersomeness represents an important measure of perceived symptom severity, but has received relatively little consideration, and relationships between symptom bothersomeness and obesity are not known. We evaluated the association between body fat percentage (%BF) and the bothersomeness of symptoms at midlife. METHODS: This cross-sectional study included women aged 40-60 in Qatar (n = 841). Participants reported frequency and bothersomeness of midlife symptoms hypothesized to be related to body composition. Initially, we characterized the relationship between continuous %BF and presence (yes/no) and bothersomeness (yes/no) for each symptom using restricted cubic spline (RCS) models to test nonlinearity. Subsequently, we used multinomial logistic regressions to evaluate associations between %BF and multilevel symptom outcomes, where categories were: (a) no symptoms or bother, (b) symptoms without bothersomeness, and (c) symptoms with bothersomeness. RESULTS: The highest frequency of bothersomeness was reported for aches/stiffness in joints (51%), followed by trouble sleeping (34%), night sweats (21%), urinary incontinence (18%), hot flashes (16%), and shortness of breath (15%). In unadjusted multinomial logistic regressions, aches/stiffness in joints with and without bothersomeness had the same significant relationship with %BF. Bothersome night sweats, urinary incontinence, and hot flashes were significantly associated with %BF (p < .05), but those same symptoms without bothersomeness were not significantly associated with %BF. CONCLUSIONS: Our findings suggest that bothersomeness is an important variable that tracks with body fat and gives different information than report of the presence/absence of a symptom alone.

Impact of Changing Distance-Learning Formats in Physical Therapy Professional Education.

AIMS: In early 2020, the COVID-19 pandemic caused a majority of higher education to shift content delivery formats to allow for social distancing to decrease spread of the virus. The purpose of this investigation was to discover physical therapy students' perceived impact from changing from a synchronous videoconferencing format to a more hybrid program format. METHODS: A qualitative case study design bounded by the time of switching formats due to the pandemic was chosen (March 2020 through September 2020). Physical therapy students participated in an agreement survey (n=38) and semi-structured interviews (n=12). Survey and interview data were coded and analyzed to form categories and themes of discovered perspectives. RESULTS: Students' perceived proficiency of hands-on skill was negatively affected. Cross-campus student and faculty interactions improved. Students felt changing formats would not result in detrimental effects on their overall learning nor on their career potential as physical therapists. DISCUSSION: Educators in entry-level professional physical therapy programs utilizing distance-education models should consider and adjust timing of hands-on skill instruction to match didactic content to encourage better connection and clinical application. Distance-learning educators should foster more interaction with students who may feel isolated. Interaction between distance-separated cohorts can reduce feelings of competition and inequality between campus locations and create improved learning communities.

Exploring the Intensity, Frequency, and Duration of Pediatric Constraint Induced Movement Therapy Published Research: A Content Analysis.

Constraint Induced Movement Therapy (CIMT) utilizes a behavioral approach to neurorehabilitation involving constraint of an unaffected upper extremity which forces the use of the affected extremity. There is substantial evidence supporting the effectiveness of CIMT among both children and adults. The purpose of this study was to explore the frequency, intensity, and duration parameters across the published clinical outcomes related to pediatric CIMT (pCIMT) among children and youth populations. A content analysis approach was used to search the following databases Google Scholar, OT seeker, American Occupational Therapy Association special interest section, Medline, EbscoHost, and Cinhal. A total of 141 studies were identified via the initial search, with 51 studies meeting inclusion criteria. The findings revealed that 100% of the studies included restraint of the non-affected upper extremity, 73% incorporated repetitive task-oriented training, but less than half prescribed home practice strategies. Further, only 34% of the studies reviewed included all three components of CIMT. Outpatient hospital clinics and home-based settings were the most utilized settings for research studies. The mean minutes per session was M = 205.53, SD = 164.99. As part of the plan of care, the duration and frequency of therapy both had similar means (~M = 3.60) and standard deviations (~SD = 1.65). There was a significant variance of hours during (SD = 139.54) and outside of therapy (SD = 130.06). The results of this study, together with other emerging evidence, can assist practitioners in prescribing dosages dependent on the setting, the pediatric client, and their current functional status.

Student Perspectives of Integrated Clinical Practicum Experiences in Physical Therapy Education: A Pilot Study.

PURPOSE: The goal of this pilot study was to discover students' perspective of clinical practicum experiences utilized for accreditation-required Integrated Clinical Experiences in doctor of physical therapy education. This study aimed to learn how students perceived the value of participating in institution-based clinical practicum experiences and the perceived utility and value of these clinical practicum experiences to their future careers in physical therapy. PROCEDURES: A case study design using an agreement survey followed by randomized semi-structured interviews with a cohort of physical therapy students provided the data to inform investigators of student perspectives regarding clinical practicum experiences. FINDINGS: Students overwhelmingly agreed that practicum adds value to their education and was worth the time spent. Students reflected that practicum was a strength of their education, provided and built upon skills above the didactic curriculum, and improved their ability to perform during full-time clinical education experiences. Students perceived that full-time clinical education experiences would have greater effect on their future career direction than clinical practicum experiences. CONCLUSION: Students perceived that clinical practicum experiences are valuable in their physical therapy education, in preparation for full-time clinical education experiences, and for beginning careers as physical therapists, but do not influence their future career direction.

Evaluation of large volume yeast interfering RNA lure-and-kill ovitraps for attraction and control of Aedes mosquitoes.

Aedes mosquitoes (Diptera: Culicidae), principle vectors of several arboviruses, typically lay eggs in man-made water-filled containers located near human dwellings. Given the widespread emergence of insecticide resistance, stable and biofriendly alternatives for mosquito larviciding are needed. Laboratory studies have demonstrated that inactivated yeast interfering RNA tablets targeting key larval developmental genes can be used to facilitate effective larvicidal activity while also promoting selective gravid female oviposition behaviour. Here we examined the efficacy of transferring this technology toward development of lure-and-kill ovitraps targeting Aedes aegypti (L.) and Aedes albopictus (Skuse) female mosquitoes. Insectary, simulated field and semi-field experiments demonstrated that two mosquito-specific yeast interfering RNA pesticides induce high levels of mortality among larvae of both species in treated large volume containers. Small-scale field trials conducted in Trinidad, West Indies demonstrated that large volume ovitrap containers baited with inactivated yeast tablets lure significantly more gravid females than traps containing only water and were highly attractive to both A. aegypti and A. albopictus females. These studies indicate that development of biorational yeast interfering RNA-baited ovitraps may represent a new tool for control of Aedes mosquitoes, including deployment in existing lure-and-kill ovitrap technologies or traditional container larviciding programs.

Compliance with hygiene practices among healthcare workers in the intensive care unit.

BACKGROUND: Intensive care unit (ICU)-related healthcare-associated infections (HCAIs) are two to three times higher in lower-income countries than in higher-income ones. Hand cleansing and other hygiene measures have been documented as one of the most effective measures in combating the transmission of HCAIs. There is a paucity of data pertaining to hygiene practices in the ICU in developing countries. OBJECTIVES: To determine compliance with hygiene practices among healthcare workers in a tertiary hospital ICU. METHODS: Hygiene practices of healthcare workers in a tertiary academic hospital ICU in Johannesburg, South Africa, were discreetly observed over an 8-week period. Compliance with hand cleansing and other hygiene practices was documented and analysed. Retrospective consent was obtained, and subject confidentiality was maintained. RESULTS: A total of 745 hygiene opportunities were observed. Of the 156 opportunities where handwashing with soap and water was indicated (20.9%), compliance was noted in 89 cases (57.1%), while an alcohol-based hand rub was inappropriately used in 34 cases (21.8%) and no hand hygiene was performed in the remaining 33 cases (21.1%). Of the 589 opportunities where an alcohol-based hand-rub was indicated, it was used in 312 cases (53.0%). Compliance with the donning of disposable surgical gloves, disposable plastic aprons and being 'bare below the elbows' was noted in 114 (90.6%), 108 (71.1%) and 355 (47.7%) opportunities, respectively, where these were indicated. CONCLUSIONS: Overall compliance with hygiene measures among healthcare workers in the ICU was suboptimal in this study, but in keeping with general international trends. Regular retraining of staff, frequent reminders, peer oversight and regular audits may improve compliance.

Tool use and social homophily among male bottlenose dolphins.

Homophilous behaviour plays a central role in the formation of human friendships. Individuals form social ties with others that show similar phenotypic traits, independently of relatedness. Evidence of such homophily can be found in bottlenose dolphins ( Tursiops aduncus) in Shark Bay, Western Australia, where females that use marine sponges as foraging tools often associate with other females that use sponges. 'Sponging' is a socially learned, time-consuming behaviour, transmitted from mother to calf. Previous research illustrated a strong female bias in adopting this technique. The lower propensity for males to engage in sponging may be due to its incompatibility with adult male-specific behaviours, particularly the formation of multi-level alliances. However, the link between sponging and male behaviour has never been formally tested. Here, we show that male spongers associated significantly more often with other male spongers irrespective of their level of relatedness. Male spongers spent significantly more time foraging, and less time resting and travelling, than did male non-spongers. Interestingly, we found no difference in time spent socializing. Our study provides novel insights into the relationship between tool use and activity budgets of male dolphins, and indicates social homophily in the second-order alliance composition of tool-using bottlenose dolphins.

Exploring the parameters of intensity, frequency, and duration within the constraint induced movement therapy published research: A content analysis.

BACKGROUND: Neurological rehabilitation specialists must determine appropriate dosage, consisting of frequency, intensity, and duration of specified treatments. OBJECTIVE: The objective of this study was to perform a content analysis of the current literature related to dosage (duration, frequency and intensity) for constraint-induced movement therapy (CIMT) in the adult population. METHODS: A content analysis was conducted which yielded 62 scholarly articles. RESULTS: The frequency of CIMT ranged from 1 to 7 days per week with the average frequency being 4.98 days. The duration of CIMT, ranged from 2 to 10 weeks with the average duration 3.14 weeks. All three components of dosage were reported collectively in outcomes studies conducted in inpatient settings and rehabilitation clinics. CONCLUSIONS: The findings provide a groundwork for evidence based practice for clinician in the application of CIMT dosage with consideration of settings and CIMT components.

The macrophage activation marker CD163 is associated with IL28B genotype and hepatic inflammation in chronic hepatitis C virus infected patients.

Recent data highlighted the association of the macrophage activation marker CD163 with histological inflammation and fibrosis in chronic hepatitis C virus (HCV) infection. The aim of this study was to investigate the influence of successful antiviral treatment and IL28B genotypes on macrophage activation reflected by CD163 levels in HCV infected patients. In a retrospective cohort study, serum sCD163 levels were correlated with results of liver histopathology, IL28B genotyping and clinical parameters in 329 patients with HCV infection, 15 healthy controls and in 161 patients who achieved a sustained virologic response after antiviral treatment. sCD163 levels were significantly higher in patients with chronic HCV infection in comparison to healthy controls (5202 vs 896 ng/mL, P < 0.001). In the multivariate logistic regression analyses, sCD163 was independently associated with histologically determined inflammation (P = 0.043) but not with fibrosis (P = 0.091). sCD163 dropped significantly after successful antiviral treatment in comparison to baseline values (5202 vs 3093 ng/mL, P < 0.001). In the univariate analyses, sCD163 was significantly associated with IL28B genotype (C/C vs C/T+T/T) with higher values in the C/C group (6098 vs 4812 ng/mL, P = 0.003). In the multivariate logistic regression model, sCD163 levels were significantly associated with IL28B genotype (P = 0.003) and sustained virologic response (SVR) (P < 0.001). Our data support the association of activated liver macrophages with hepatic necroinflammation in chronic HCV infection as sCD163 levels drop rapidly after SVR. The irresponsiveness of IL28B minor genotypes to interferon might be related to a lower level of macrophage activation in these patients.

Ledipasvir/sofosbuvir treatment of hepatitis C virus is associated with reduction in serum apolipoprotein levels.

The interaction of lipoproteins with hepatitis C virus (HCV) has pathogenic and therapeutic implications. Our aim was to evaluate changes in the apolipoprotein profile of patients with chronic hepatitis C during and after successful cure with ledipasvir and sofosbuvir (LDV/SOF) with and without ribavirin (RBV). One hundred HCV genotype 1 patients who had achieved SVR-12 after treatment with 12 weeks of LDV/SOF ± RBV were selected from the ION-1 clinical trial. Frozen serum samples from baseline, end of treatment and week 4 of follow-up were used to assay apolipoproteins (apoAI, apoAII, apoB, apoCII, apoCIII, apoE) using the Multiplex platform to assess for changes in the apolipoprotein levels. At the end of treatment compared to baseline, a significant reduction in apoAII levels (-14.97 ± 63.44 µg/mL, P = 0.0067) and apoE levels (-4.38 ± 12.19 µg/mL, P < 0.001) was noted. These declines from baseline in apoAII (-16.59 ±66.15 µg/mL, P = 0.0075) and apoE (-2.66 ± 12.64 µg/mL, P = 0.015) persisted at 4 weeks of post-treatment follow-up. In multivariate analysis, treatment with LDV/SOF + RBV was independently associated with reduction in apoE (beta = 5.31 µg/mL, P = 0.002) (compared to RBV-free LDV/SOF) (P < 0.05). In contrast, apoCII levels overall increased from baseline to end of treatment (+2.74 ±11.76 µg/mL, P = 0.03) and persisted at 4 weeks of follow-up (+4.46 ± 12.81 µg/mL from baseline, P = 0.0005). Subgroup analysis revealed an increase in apoCII during treatment only in patients receiving LDV/SOF without RBV (+5.52 ± 11.92 µg/mL, P = 0.0007) but not in patients receiving LDV/SOF + RBV (P = 0.638). Treatment with LDV/SOF ± RBV is associated with a persistent reduction in the apolipoprotein AII and E after achieving cure. These data suggest that treatment with LDV/SOF ± RBV may be associated with alterations in serum apolipoproteins which could potentially impact viral eradication.

Bone mineral density in midlife women: the Study of Women's Health in Qatar.

OBJECTIVES: The aim of this study is to investigate bone mineral density (BMD) for a large cross-section of midlife Arab women living in Qatar and to evaluate the association of body mass index (BMI), menopause status, and nationality, on BMD of the spine and femur. STUDY DESIGN: A cross-sectional study was conducted among women aged 40-60 years recruited from nine primary-care health centers in Qatar. BMD (g/m(2)) was assessed at the lumbar spine and the femur. RESULTS: The combined prevalence of osteopenia and osteoporosis was 4% at the femur and 16.2% at the spine. BMI and menstrual status were both independently associated with BMD at the spine and at the femur (all p values < 0.001). As BMI increased, BMD increased at both the spine and femur. Women who menstruated in the past 12 months had 0.82 g/cm(2) and 0.61 g/cm(2) greater BMD at the spine and femur, respectively, compared with women who had not menstruated in 12 months. Nationality was not associated with mean BMD of the spine or the femur. CONCLUSIONS: No significant differences were observed between Qatari and non-Qatari women in terms of mean BMD values at the spine and the femur except for the femur in the age group 55-60, where values were lower among non-Qataris (p = 0.04). Multivariable analyses showed that BMI and menstrual status were found to be strongly associated with BMD levels at the spine and femur. The high prevalence of obesity observed in this sample may explain the low levels of osteopenia and osteoporosis observed.

Soluble CD163 is an indicator of liver inflammation and fibrosis in patients chronically infected with the hepatitis B virus.

Soluble CD163 (sCD163), a marker for macrophage activation, was found to be associated with the severity of liver cirrhosis. The aim of the current study was to investigate whether serum sCD163 levels correlate with liver inflammation and fibrosis in patients with chronic hepatitis B virus (HBV) infection. In a retrospective cohort study, serum sCD163 levels were assessed by ELISA together with clinical and laboratory data in 186 patients with chronic HBV infection and 15 healthy controls. The relation between parameters for liver fibrosis and necroinflammation and sCD163 levels was analysed. Additionally, sCD163 was quantified in a subset of follow-up serum samples after initiation of antiviral treatment. sCD163 levels differed among phases of chronic HBV infection (P < 0.0001), and sCD163 concentrations were associated with inflammatory activity and fibrosis in the liver. sCD163 levels ≥ 1961 ng/l had a high specificity in the identification of subjects with substantial fibrosis (F ≥ 2). sCD163 concentrations decreased significantly after initiation of antiviral treatment. The correlation of sCD163 levels with necroinflammation and fibrosis and the sCD163 decline under treatment indicates that macrophage activation plays a role in HBV-related liver pathogenesis.

Use of complementary and alternative medicine among midlife Arab women living in Qatar.

The prevalence of use of complementary and alternative medicine (CAM) is widespread and is growing worldwide. This cross-sectional study in Qatar examined the use of CAM and its correlates among Arab women in their midlife years. Women aged 40-60 years (n = 814) were recruited at primary care centres in Qatar and completed a specially designed, pre-tested questionnaire. Overall, 38.2% of midlife women in Qatar had used CAM in the previous 12 months. Nutritional remedies and herbal remedies were the most commonly used CAM therapies, followed by physical methods. Qatari nationality and higher level of education were independently associated with CAM use. Menopause transition status was not independently associated with use of CAM. The prevalence of CAM use by women in Qatar was high, consistent with other reports worldwide. It is essential to educate and inform patients and health-care providers about the benefits and limitations associated with CAM.

Endoscopic assessment of the duodenum in dogs with inflammatory bowel disease.

BACKGROUND: Endoscopy is performed for direct inspection of the mucosa and acquisition of biopsies in dogs with inflammatory bowel disease (IBD). AIM: To evaluate the interobserver agreement in the endoscopic assessment of duodenal mucosa in dogs with IBD. METHODS: Thirty-five archived endoscopic images of grossly normal (n = 6) and inflamed (n = 29) duodenal mucosa were displayed to 3 expert and 5 trainee endoscopists. Each image was assessed independently by endoscopists for mucosal abnormalities using established indices (of hyperemia, granularity, friability, lymphatic dilatation, and erosions) or interpreted as normal mucosa (trial 1). A repeated trial (trial 2) was performed with the same images presented in random order 1 month later, and accompanied by a visual template. RESULTS: There was slight interobserver agreement in initial mucosal assessment for expert and trainee endoscopists in trial 1 (kappa ≤ 0.02, P > .05). Interobserver agreement improved in trial 2 for both expert and trainee endoscopists (kappa = 0.2, P > .05) for experts and (P < .05) for trainees. There was a significant (P < .01) improvement in trainee endoscopy scores of lesions from trial 1 to trial 2. Regression analysis showed a significant (P < .01) difference between expert versus trainee endoscopy scores in trial 1. Repeat lesion assessment aided by use of a visual template (trial 2) improved the overall scores of trainee endoscopists to near that of expert endoscopists (P = .06). CONCLUSIONS AND CLINICAL IMPORTANCE: Interobserver agreement of IBD mucosal appearance from endoscopic findings benefitted from operator experience.

L'utilisation des médecines complémentaires et parallèles est largement prévalent et en augmentation dans le monde. La présente étude transversale au Qatar à examiné le recours aux médecines complémentaires et parallèles et ses corrélats chez des femmes arabes en milieu de vie. Des femmes âgées de 40 à 60 ans [n = 814] ont été recrutées dans des centres de soins de santé primaires au Qatar et ont rempli un questionnaire spécialement conçu ayant été testé au préalable. Au total 38,2% des femmes en milieu de vie interrogées vivant au Qatar avaient eu recours aux médecines complémentaires et parallèles durant les 12 mois précédents. Des remèdes nutritionnels et à base de plantes étaient les traitements complémentaires et parallèles les plus fréquemment utilisés, suivis par des méthodes physiques. La nationalité qatarie et un niveau d'études plus élevé étaient indépendamment associés à l'utilisation de médecines complémentaires et parallèles. Le statut de transition ménopausique n'était pas indépendamment associé à l'utilisation de ces médecines. La prévalence de leur utilisation chez les femmes au Qatar était élevée et concordait avec les études menées sur le sujet dans d'autre pays du monde. Il est essentiel d'éduquer et d'informer les patientes et les prestataires de soins de santé sur les bénéfices et les limites associés aux médecines complémentaires et parallèles

Severe and moderate haemophilia A and B in US females.

Haemophilia A and B are rare X-lined hemorrhagic disorders that typically affect men. Women are usually asymptomatic carriers, but may be symptomatic and, rarely, also express severe (factor VIII (FVIII) or factor IX (FIX) <0.01 U mL(-1)) or moderately severe (FVIII/FIX 0.01-0.05 U mL(-1)) phenotypes. However, data on clinical manifestations, genotype and the psychosocial ramifications of illness in severely affected females remain anecdotal. A national multi-centre retrospective study was conducted to collect a comprehensive data set on affected US girls and women, and to compare clinical observations to previously published information on haemophilic males of comparable severity and mildly affected haemophilic females. Twenty-two severe/moderate haemophilia A/B subjects were characterized with respect to clinical manifestations and disease complications; genetic determinants of phenotypic severity; and health-related quality of life (HR-QoL). Clinical data were compared as previously indicated. Female patients were older than male patients at diagnosis, but similarly experienced joint haemorrhage, disease- and treatment-related complications and access to treatment. Gynaecological and obstetrical bleeding was unexpectedly infrequent. F8 or F9 mutations, accompanied by extremely skewed X-chromosome inactivation pattern (XIP), were primary determinants of severity. HR-QoL was diminished by arthropathy and viral infection. Using systematic case verification of participants in a national surveillance registry, this study elucidated the genetics, clinical phenotype and quality of life issues in female patients with severe/moderate haemophilia. An ongoing international case-controlled study will further evaluate these observations. Novel mechanistic questions are raised about the relationship between XIP and both age and tissue-specific FVIII and FIX expression.

Metformin does not affect risk of biochemical recurrence following radical prostatectomy: results from the SEARCH database.

BACKGROUND: While epidemiologic studies suggest that metformin use among diabetics may decrease prostate cancer (PC) incidence, the effect of metformin use on PC outcome is unclear. We investigated the association between pre-operative metformin use, dose and duration of use and biochemical recurrence (BCR) in PC patients with diabetes who underwent radical prostatectomy (RP). METHODS: We conducted a retrospective cohort analysis within the Shared Equal Access Regional Cancer Hospital (SEARCH) database of 371 PC patients with diabetes who underwent RP. Time to BCR between metformin users and non-users, and by metformin dose and duration of use was assessed using multivariable Cox proportional analysis adjusted for demographic, clinical and/or pathologic features. Time to castrate-resistant PC (CRPC), metastases and PC-specific mortality were explored as secondary outcomes using unadjusted analyses. RESULTS: Of 371 diabetic men, 156 (42%) were using metformin before RP. Metformin use was associated with more recent year of surgery (P<0.0001) but no clinical or pathologic characteristics. After adjustment for year of surgery, clinical and pathologic features, there were no associations between metformin use (hazard ratio (HR) 0.93; 95% confidence interval (CI) 0.61-1.41), high metformin dose (HR 0.96; 95% CI 0.57-1.61) or duration of use (HR 1.00; 95% CI 0.99-1.02) and time to BCR. A total of 14 patients (3.8%) developed CRPC, 10 (2.7%) distant metastases and 8 (2.2%) died from PC. Unadjusted analysis suggested that high metformin dose vs non-use was associated with increased risk of CRPC (HR 5.1; 95% CI 1.6-16.5), metastases (HR 4.8; 95% CI 1.2-18.5) and PC-specific mortality (HR 5.0; 95% CI 1.1-22.5). CONCLUSIONS: Metformin use, dose or duration of use was not associated with BCR in this cohort of diabetic PC patients treated with RP. The suggestion that higher metformin dose was associated with increased risk of CRPC, metastases and PC-specific mortality merits testing in large prospective studies with longer follow-up.

Statin use and risk of prostate cancer and high-grade prostate cancer: results from the REDUCE study.

BACKGROUND: Statins are associated with lower PSA levels. As PSA is the primary method for prostate cancer (PC) screening, this confounds any associations between statins and risk of being diagnosed with PC. Thus, we examined the association between statins and cancer and high-grade cancer in REDUCE, where biopsies were largely PSA-independent. METHODS: Post-hoc secondary analysis of REDUCE, which was a prospective multinational randomized controlled trial of dutasteride vs placebo for 4 years among men aged 50-75 years with PSA of 2.5-10.0 ng ml(-1) and a negative biopsy at baseline, and included PSA-independent biopsies mandated at 2- and 4-years. Analyses were limited to men who underwent at least one biopsy while under study (n=6729). The association between baseline statin use and risk of overall, high-grade (Gleason ≥ 7) or low-grade (Gleason ≤ 6) PC vs no cancer was examined using multinomial logistic regression adjusting for age, race, baseline PSA, prostate volume, rectal examination findings, body mass index (BMI), comorbidities, smoking, alcohol intake and treatment arm. RESULTS: Of 6729 men who had at least one biopsy while on study, 1174 (17.5%) were taking a statin at baseline. Men taking statins were older, had lower PSA levels, higher BMI values and lower serum testosterone and dihydrotestosterone levels, though differences, were slight. Statin use was not associated with overall PC diagnosis (multivariable OR 1.05, 95% CI 0.89-1.24, P=0.54). When stratified by grade, statin use was not associated with low-grade (multivariable OR 1.03, 95% CI 0.85-1.25, P=0.75) or high-grade cancer (multivariable OR 1.11, 95% CI 0.85-1.45, P=0.46). The major limitation is the inclusion of only men with a negative baseline biopsy. CONCLUSIONS: Among men with a negative baseline biopsy and follow-up biopsies largely independent of PSA, statins were not associated with cancer or high-grade cancer.

Sexual bother and function after radical prostatectomy: predictors of sexual bother recovery in men despite persistent post-operative sexual dysfunction.

Changes in sexual bother (SB) following radical prostatectomy (RP) negatively affect health-related quality of life (HRQoL) of prostate cancer survivors. However, post-operative SB tends to be neglected whereas sexual function (SF) is thoroughly assessed in clinical practice and few studies have focused on and evaluated patients' SB. We retrospectively reviewed 2 345 consecutive patients who underwent RP between 2001 and 2009 at a single institution. SF and SB were assessed using Expanded Prostate Cancer Index Composite (EPIC) questionnaires. We stratified our cohort by SB recovery and post-operative SF status, including a subset of men who recovered SB despite persistent post-RP sexual dysfunction. Multivariable logistic regression analyses were conducted to identify factors for men who have SB recovery. Of 319 eligible patients, 133 (41.7%) recovered their SB at a mean of 20 months after RP. Among the 133 men who demonstrated SB recovery, 109 had post-operative sexual dysfunction. Patients with SB recovery despite post-RP sexual dysfunction were more likely to be old (p = 0.004), to have higher clinical T stage (p < 0.001), to have more non-nerve-sparing RP (p < 0.001), to have lower pre-operative EPIC-SF/SB scores (p < 0.001), to have more extracapsular extension (p = 0.031) and to be PDE5i non-users after surgery (p < 0.001). In multivariable analysis, predictors for this subset were lower comorbidity (OR 0.62, p = 0.043), higher clinical cancer stage (OR 2.35, p = 0.026), worse pre-operative SF (OR 0.98, p = 0.010), SB (OR 0.98, p < 0.010) and no PDE5i use (OR 0.37, p = 0.002); age was not related (OR 0.99, p = 0.555). As SB can influence patients' overall HRQoL, expectations of SB recovery should be provided to patients in the same way that SF recovery is presented. This study may help clinicians to discuss SB with patients and assess their potential for SB recovery following RP.

The hopeless age? A qualitative exploration of the experience of menopause in Arab women in Qatar.

OBJECTIVE: The aim of this study was qualitatively to describe and examine the expectations and experiences of the midlife transition in Arab women living in Qatar. METHOD: Six focus groups were conducted with Arab women living in Qatar: three groups of local Qatari women, and three groups of non-Qatari Arab women originating from neighboring countries. A purposive sample of 41 pre-, peri-, and postmenopausal women aged 40-60 years participated. The semi-structured group format encouraged discussion around knowledge about menopause; physical, emotional and social experiences related to menopause; and cultural differences that may exist related to menopause. RESULTS: The majority of women considered menopause as a maturing experience, although the term 'menopause' was considered to have negative connotations. Postmenopausal women described menopausal symptoms consistent with general knowledge, but many premenopausal women were unaware of symptoms, even if they knew someone who had experienced menopause. Postmenopausal women were more socially active than before and were able to participate in religious activities that they previously could not attend during menses. How a woman experienced menopause depended on the husband's level of support, and some women believed that Western women did not have the appropriate support from husbands and families that Arab women have; they felt this lack of support could lead to negative outcomes such as being at an increased risk for suicide caused by depression during menopause. CONCLUSION: Qatari and non-Qatari women had many similarities in how they perceived and experienced menopause, although they collectively believed that the experiences of Western women are different.
