Greene Climacteric Scale: norms in an Australian population in relation to age and menopausal status

Objectives The aim of this study was two-fold: to assess climacteric symptoms and provide normative data for the Greene Climacteric Scale during the menopause transition, and to investigate the prevalence of climacteric symptoms in a representative sample of postmenopausal Australian women. Method A cohort of 500 premenopausal, perimenopausal and postmenopausal women aged 40-80 years participated in the Longitudinal Study of Ageing in Women (LAW study) at the Royal Brisbane and Women's Hospital, Brisbane, Australia. In year 1 of the study (2001), all participants completed the Greene Climacteric Scale and information regarding their menopausal status and the use of hormone therapy (HT) was obtained through a clinical interview with a qualified medical practitioner. Results The 50-59-year age group achieved the highest scores on the vasomotor and the depression scales in comparison to other age groups. Significant differences were also evident on the vasomotor and the depression scales on the basis of menopausal status, especially in perimenopausal women. Approximately 10% of women in the 60-79-year age group continued to experience vasomotor symptoms. Conclusion Vasomotor symptoms, as assessed by the Greene Climacteric Scale, are common during the menopause transition and remain elevated for some years in a minority of older postmenopausal women. The norms presented in this study are appropriate for use in an Australian population.

The impact of rehabilitation support services on health-related quality of life for women with breast cancer

As the number of women surviving breast cancer increases, with implications for the health system, research into the physical and psychosocial sequelae of the cancer and its treatment is a priority. This research estimated self-reported health-related quality of life (HRQoL) associated with two rehabilitation interventions for breast cancer survivors, compared to a non-intervention group. Women were selected if they received an early home-based physiotherapy intervention (DAART, n = 36) or a group-based exercise and psychosocial intervention (STRETCH, n = 31). Questionnaires on HRQoL, using the Functional Assessment of Cancer Therapy - Breast Cancer plus Arm Morbidity module, were administered at pre-, post-intervention, 6- and 12-months post-diagnosis. Data on a non-intervention group (n = 208) were available 6- and 12-months post-diagnosis. Comparing pre/post-intervention measures, benefits were evident for functional well-being, including reductions in arm morbidity and upper-body disability for participants completing the DAART service at one-to-two months following diagnosis. In contrast, minimal changes were observed between pre/post-intervention measures for the STRETCH group at approximately 4-months post-diagnosis. Overall, mean HRQoL scores (adjusted for age, chemotherapy, hormone therapy, high blood pressure and occupation type) improved gradually across all groups from 6- to 12-months post-diagnosis, and no prominent differences were found. However, this obscured declining HRQoL scores for 20-40% of women at 12 months post-diagnosis, despite receiving supportive care services. Greater awareness and screening for adjustment problems among breast cancer survivors is required throughout the disease trajectory. Early physiotherapy after surgery has the potential for short-term functional, physical and overall HRQoL benefits.

EGFR amplification and lack of activating mutations in metaplastic breast carcinomas

Metaplastic breast carcinomas are reported to harbour epidermal growth factor receptor (EGFR) overexpression in up to 80% of the cases, but EGFR gene amplification is the underlying genetic mechanism in around one-third of these. In this study, EGFR gene amplification as defined by chromogenic in situ hybridization and protein overexpression was examined in a cohort of 47 metaplastic breast carcinomas. Furthermore, the presence of activating EGFR mutations in exons 18, 19, 20, and 21 was investigated. Thirty-two cases showed EGFR overexpression and of these, 11 (34%) harboured EGFR gene amplification. In addition, EGFR amplification showed a statistically significant association with EGFR overexpression (p < 0.0094) and was restricted to carcinomas with homologous metaplasia. Ten cases, five with and five without EGFR amplification, were subjected to microarray-based CGH, which demonstrated that EGFR copy number gain may occur by amplification of a discrete genomic region or by gains of the short arm of chromosome 7 with a breakpoint near the EGFR gene locus, the minimal region of amplification mapping to EGFR, LANCL2, and SECOG. No activating EGFR mutations were identified, suggesting that this is unlikely to be a common alternative underlying genetic mechanism for EGFR expression in metaplastic breast carcinomas. Given that metaplastic breast carcinomas are resistant to conventional chemotherapy or hormone therapy regimens and that tumours with EGFR amplification are reported to be sensitive to EGFR tyrosine kinase inhibitors, these findings indicate that further studies are warranted to explore EGFR tyrosine kinase inhibitors as potential therapeutic agents for metaplastic breast carcinomas harbouring amplification of 7p11.2.

A prosztatarák gazdasági terhe nagy betegregiszterek alapján (The economic burden of prostate cancer. A systematic literature overview of registry-based studies)

INTRODUCTION: Prostate cancer, the most frequent malignant disease in males in Europe, accounts for a great proportion of health expenditures. AIM: A systematic review of registry-based studies about the cost-of-illness and related factors of prostate cancer, published in the last 10 years. METHOD: A MEDLINE-based literature review was carried out between January 1, 2003 and October 1, 2013. RESULTS: Fifteen peer-reviewed articles met the criteria of interest. In developed countries radiotherapy, surgical treatment and hormone therapy account for the greatest per capita costs. In Europe early stage tumours (4-7000 €, 2006), while in the USA metastatic prostate cancer (19 900-25 500 $, 2004) was associated with highest per capita expenses. In Europe the greatest costs incurred within the initial treatment (6400 €/6 months, 2008), while in the USA within the end-of-life care (depending on age: 62 200-93 400 $, 2010). CONCLUSIONS: Despite public health importance of prostate cancer, the cost-of-illness literature from Europe is relatively small.

Estrogen and lithium: Facilitating factors involved in brain cell signaling pathways

Learning and memory in adult females decline during menopause and estrogen replacement therapy is commonly prescribed during menopause. Post-menopausal women tend to suffer from depression and are prescribed antidepressants – in addition to hormone therapy. Estrogen replacement therapy is a topic that engenders debate since several studies contradict its efficacy as a palliative therapy for cognitive decline and neurodegenerative diseases. Signaling transduction pathways can alter brain cell activity, survival, and morphology by facilitating transcription factor DNA binding and protein production. The steroidal hormone estrogen and the anti-depressant drug lithium interact through these signaling transduction pathways facilitating transcription factor activation. The paucity of data on how combined hormones and antidepressants interact in regulating gene expression led me to hypothesize that in primary mixed brain cell cultures, combined 17β-estradiol (E2) and lithium chloride (LiCl) (E2/LiCl) will alter genetic expression of markers involved in synaptic plasticity and neuroprotection. Results from these studies indicated that a 48 h treatment of E2/LiCl reduced glutamate receptor subunit genetic expression, but increased neurotrophic factor and estrogen receptor genetic expression. Combined treatment also failed to protect brain cell cultures from glutamate excitotoxicity. If lithium facilitates protein signaling pathways mediated by estrogen, can lithium alone serve as a palliative treatment for post-menopause? This question led me to hypothesize that in estrogen-deficient mice, lithium alone will increase episodic memory (tested via object recognition), and enhance expression in the brain of factors involved in anti-apoptosis, learning and memory. I used bilaterally ovariectomized (bOVX) C57BL/6J mice treated with LiCl for one month. Results indicated that LiCl-treated bOVX mice increased performance in object recognition compared with non-treated bOVX. Increased performance in LiCl-treated bOVX mice coincided with augmented genetic and protein expression in the brain. Understanding the molecular pathways of estrogen will assist in identifying a palliative therapy for menopause-related dementia, and lithium may serve this purpose by acting as a selective estrogen-mediated signaling modulator.

The effect of different instructional groupings on student achievement and attitudes from a computer-based interactive videodisk biology unit

The purpose of this research study was to determine the effect of two different instructional groupings (cooperative and traditional whole-class) on student achievement and attitudes using a computer-based interactive videodisc biology unit. The subjects were 64 high school biology students assigned to two heterogeneous experimental groups, randomly selected from two preassigned summer school biology classes, one honors, the other regular. A two-group, posttest-only, control group experimental research design was utilized. Achievement at three cognitive levels and attitudes towards science laserdisc instruction were measured at the conclusion of the study. The cooperative group consistently outperformed the traditional group in achievement posttest scores. Factorial ANOVA on total (overall) achievement scores indicated that subjects in cooperative groups significantly outperformed those in the traditional group, and also that the instructional group, class level, and gender interacted in an ordinal fashion to make a significant difference in how female and male subjects were affected by the treatments depending on their class (aptitude) level. Regular level females and honors level males performed much better when in cooperative groups, whereas group membership did not appear to make a difference for either honors level females or regular level males. A t-test comparing honors level males revealed that cooperative groups were close to being significantly better in total achievement posttest scores than their traditional group counterparts. Factorial MANOVA comparing the instructional groups at three cognitive levels found no significant difference. Analysis on the attitudes posttest data also revealed that subjects in cooperative groups demonstrated more positive attitudes towards science laserdisc instruction; however these differences were not found to be significant. Significant interactions in attitudes of females and males from different class levels had the opposite effect as achievement: honors level females and regular level males demonstrated more positive attitudes towards science laserdisc instruction when in cooperative groups, whereas group membership did not appear to make a difference for honors level males, and regular level females demonstrated the lowest attitudes ratings of any group when involved in cooperative groups. This contrast between achievement and attitudinal results suggests cross-gender interaction in traditionally defined gender roles.

Travestis na atenção primária: o cuidado em saúde na cidade de Natal

Among the deviant a heteronormative ideal, transvestites are the ones that suffer abuse and discrimination. Have been found that health services often present themselves as places that maintains and reproduce such discrimination, which makes transvestites only sought medical care in the latter case. Based on the guidelines of the SUS and the National Humanization Policy as well as the inclusion and leadership of the users, we conducted a qualitative study seeking to understand the experience of transvestites in seeking health care within primary care in Natal-RN. We use as techno-methodological instruments in depth interview and workshop with use of "scenes". For interpretative analysis of the narratives we use to Hermeneutics-Dialectic. From the dialogue with the narrative we come to the following themes: 1) Understanding the meaning of being a transvestite; 2) The experience transvestite in search of health; 3) Transvestites and humanized health care. In the first point they reveal the daily struggle of transvestites between prejudice and the search for respect, as well as the meanings of being a transvestite, who appeared as: Being gay, being feminine, not transsexual and accept themselves as they are. In the second axis, expressed difficulties in access to and use of health services: the embarrassment by not using the social name; fear of going out during the day; the association of transvestites to HIV; and pain caused by discrimination from health professionals. It was also possible to identify simple demands such as illnesses from day to day, the demand for hormone therapy, which involves treatment needs as well as the vital need to have their rights XVII respected. The third axis, for the range of a humanized care identified that the respectful gaze guarantee their dignity and their right to health in a humane way, but it identified some necessary changes: Training of professionals, dialogue with the social movement, publicity campaigns and rapprochement with the transvestite. Finally, it is expected that the research will contribute to the field of knowledge know-how in health care transvestites, inside and outside of the university

Novel surface-tethered estrogen polymeric platforms in cardiovascular regenerative medicine

L’estradiol (E2) est une hormone femelle qui joue un rôle essentiel, à la fois dans la régulation et dans la détermination de certaines conditions physiologiques in vivo, telle que la différenciation et la prolifération cellulaire. Lorsque l’E2 est donné en supplément, par exemple dans le cas de thérapie hormonale, deux effets sont observés, un effet génomique et un effet non-génomique, de par son interaction avec les récepteurs à œstrogène du noyau ou de la membrane cellulaire, respectivement. L’effet non-génomique est plus difficile à étudier biologiquement parce que l’effet se produit sur une échelle de temps extrêmement courte et à cause de la nature hydrophobe de l’E2 qui réduit sa biodisponibilité et donc son accessibilité aux cellules cibles. C’est pourquoi il est nécessaire de développer des systèmes d’administration de l’E2 qui permettent de n’étudier que l’effet non-génomique de l’œstrogène. Une des stratégies employée consiste à greffer l’E2 à des macromolécules hydrophiles, comme de l’albumine de sérum bovin (BSA) ou des dendrimères de type poly(amido)amine, permettant de maintenir l’interaction de l’E2 avec les récepteurs d’œstrogène de la membrane cellulaire et d’éviter la pénétration de l’E2 dans le noyau des cellules. Toutefois, ces systèmes macromolécules-E2 sont critiquables car ils sont peu stables et l’E2 peut se retrouver sous forme libre, ce qui affecte sa localisation cellulaire. L’objectif de cette thèse est donc de développer de nouvelles plateformes fonctionnalisées avec de l’E2 en utilisant les approches de synthèses ascendantes et descendantes. Le but de ces plateformes est de permettre d’étudier le mécanisme de l’effet non-génomique de l’E2, ainsi que d’explorer des applications potentielles dans le domaine biomédical. L’approche ascendante est basée sur un ligand d’E2 activé, l’acide 17,α-éthinylestradiol-benzoïque, attaché de façon covalente à un polymère de chitosan avec des substitutions de phosphorylcholine (CH-PC-E2). L’estradiol est sous forme de pro-drogue attachée au polymère qui s’auto-assembler pour former un film. L’effet biologique de la composition chimique du film de chitosan-phosphorylcholine a été étudié sur des cellules endothéliales. Les films de compositions chimiques différentes ont préalablement été caractérisés de façon physicochimique. La topographie de la surface, la charge de surface, ainsi que la rhéologie des différents films contenant 15, 25, ou 40% molaires de phosphorylcholine, ont été étudiés par microscopie à force atomique (AFM), potentiel zêta, résonance plasmonique de surface et par microbalance à cristal de quartz avec dissipation (QCM-D). Les résultats de QCM-D ont montré que plus la part molaire en phosphorylcholine est grande moins il y a de fibrinogène qui s’adsorbe sur le film de CH-PC. Des cellules humaines de veine ombilicale (HUVECs) cultivées sur des films de CH-PC25 et de CH-PC40 forment des amas cellulaire appelés sphéroïdes au bout de 4 jours, alors que ce n’est pas le cas lorsque ces cellules sont cultivées sur des films de CH-PC15. L’attachement de l’estradiol au polymère a été caractérisé par plusieurs techniques, telles que la résonance magnétique nucléaire de proton (1H NMR), la spectroscopie infrarouge avec transformée de Fourier à réfraction totale atténuée (FTIR-ATR) et la spectroscopie UV-visible. La nature hydrogel des films (sa capacité à retenir l’eau) ainsi que l’interaction des films avec des récepteurs à E2, ont été étudiés par la QCM-D. Des études d’imagerie cellulaires utilisant du diacétate de diaminofluoresceine-FM ont révélé que les films hydrogels de CH-PC-E2 stimulent la production d’oxyde nitrique par les cellules endothéliales, qui joue un rôle protecteur pour le système cardiovasculaire. L’ensemble de ces études met en valeur les rôles différents et les applications potentielles qu’ont les films de type CH-PC-E2 et CH-PC dans le cadre de la médecine cardiovasculaire régénérative. L’approche descendante est basée sur l’attachement de façon covalente d’E2 sur des ilots d’or de 2 μm disposés en rangées et espacés par 12 μm sur un substrat en verre. Les ilots ont été préparés par photolithographie. La surface du verre a quant à elle été modifiée à l’aide d’un tripeptide cyclique, le cRGD, favorisant l’adhésion cellulaire. L’attachement d’E2 sur les surfaces d’or a été suivi et confirmé par les techniques de SPR et de QCM-D. Des études d’ELISA ont montré une augmentation significative du niveau de phosphorylation de la kinase ERK (marqueur important de l’effet non-génomique) après 1 heure d’exposition des cellules endothéliales aux motifs alternant l’E2 et le cRGD. Par contre lorsque des cellules cancéreuses sont déposées sur les surfaces présentant des motifs d’E2, ces cellules ne croissent pas, ce qui suggère que l’E2 n’exerce pas d’effet génomique. Les résultats de l’approche descendante montrent le potentiel des surfaces présentant des motifs d’E2 pour l’étude des effets non-génomiques de l’E2 dans un modèle in vitro.

Overweight duration in older adults and cancer risk: a study of cohorts in Europe and the United States

Recent studies have shown that cancer risk related to overweight and obesity is mediated by time and might be better approximated by using life years lived with excess weight. In this study we aimed to assess the impact of overweight duration and intensity in older adults on the risk of developing different forms of cancer. Study participants from seven European and one US cohort study with two or more weight assessments during follow-up were included (n = 329,576). Trajectories of body mass index (BMI) across ages were estimated using a quadratic growth model; overweight duration (BMI ≥ 25) and cumulative weighted overweight years were calculated. In multivariate Cox models and random effects analyses, a longer duration of overweight was significantly associated with the incidence of obesity-related cancer [overall hazard ratio (HR) per 10-year increment: 1.36; 95 % CI 1.12-1.60], but also increased the risk of postmenopausal breast and colorectal cancer. Additionally accounting for the degree of overweight further increased the risk of obesity-related cancer. Risks associated with a longer overweight duration were higher in men than in women and were attenuated by smoking. For postmenopausal breast cancer, increased risks were confined to women who never used hormone therapy. Overall, 8.4 % of all obesity-related cancers could be attributed to overweight at any age. These findings provide further insights into the role of overweight duration in the etiology of cancer and indicate that weight control is relevant at all ages. This knowledge is vital for the development of effective and targeted cancer prevention strategies.

Comorbidity in severe asthma requiring systemic corticosteroid therapy: cross-sectional data from the Optimum Patient Care Research Database and the British Thoracic Difficult Asthma Registry

Objective: To determine the prevalence of systemic corticosteroid-induced morbidity in severe asthma.
Design: Cross-sectional observational study.Setting The primary care Optimum Patient Care Research Database and the British Thoracic Society Difficult Asthma Registry.
Participants: Optimum Patient Care Research Database (7195 subjects in three age- and gender-matched groups)—severe asthma (Global Initiative for Asthma (GINA) treatment step 5 with four or more prescriptions/year of oral corticosteroids, n=808), mild/moderate asthma (GINA treatment step 2/3, n=3975) and non-asthma controls (n=2412). 770 subjects with severe asthma from the British Thoracic Society Difficult Asthma Registry (442 receiving daily oral corticosteroids to maintain disease control).
Main outcome measures: Prevalence rates of morbidities associated with systemic steroid exposure were evaluated and reported separately for each group.
Results: 748/808 (93%) subjects with severe asthma had one or more condition linked to systemic corticosteroid exposure (mild/moderate asthma 3109/3975 (78%), non-asthma controls 1548/2412 (64%); p<0.001 for severe asthma versus non-asthma controls). Compared with mild/moderate asthma, morbidity rates for severe asthma were significantly higher for conditions associated with systemic steroid exposure (type II diabetes 10% vs 7%, OR=1.46 (95% CI 1.11 to 1.91), p<0.01; osteoporosis 16% vs 4%, OR=5.23, (95% CI 3.97 to 6.89), p<0.001; dyspeptic disorders (including gastric/duodenal ulceration) 65% vs 34%, OR=3.99, (95% CI 3.37 to 4.72), p<0.001; cataracts 9% vs 5%, OR=1.89, (95% CI 1.39 to 2.56), p<0.001). In the British Thoracic Society Difficult Asthma Registry similar prevalence rates were found, although, additionally, high rates of osteopenia (35%) and obstructive sleep apnoea (11%) were identified.

Conclusions: Oral corticosteroid-related adverse events are common in severe asthma. New treatments which reduce exposure to oral corticosteroids may reduce the prevalence of these conditions and this should be considered in cost-effectiveness analyses of these new treatments.

Gender inequity in the provision of care for hip disease: population-based cross-sectional study

Objectives To examine gender differences along the care pathway to total hip replacement. Methods We conducted a population-based cross-sectional study of 26,046 individuals aged 35 years and over in Avon and Somerset. Participants completed a questionnaire asking about care provision at five milestones on the pathway to total hip replacement. Those reporting hip disease were invited to a clinical examination. We estimated odds ratios (ORs) [95% confidence intervals (CI)] for provision of care to women compared with men. Results 3169 people reported hip pain, 2018 were invited for clinical examination, and 1405 attended (69.6%). After adjustment for age and disease severity, women were less likely than men to have consulted their general practitioner (OR 0.78, 95%-CI 0.61–1.00), as likely as men to have received drug therapy for hip pain in the previous year (OR 0.96, 95%-CI 0.74–1.24), but less likely to have been referred to specialist care (OR 0.53, 95%-CI 0.40–0.70), to have consulted an orthopaedic surgeon (OR 0.50, 95%-CI 0.32–0.78), or to be on a waiting list for total hip replacement (OR 0.41, 95%-CI 0.20–0.87). Differences remained in the 746 people who had sought care from their general practitioner, and after adjustment for willingness and fitness for surgery. Conclusions There are gender inequalities in provision of care for hip disease in England, which are not fully accounted for by gender differences in care seeking and treatment preferences. Differences in referral to specialist care by general practitioners might unwittingly contribute to this inequity. Accurate information about availability, benefits and risks of hip replacement for providers and patients, and continuing education to ensure that clinicians interpret and correct patients' assumptions could help reduce inequalities.
