RESUMO

BACKGROUND: A prognostic model was developed and validated using cancer registry data. This underpins an online decision support tool, informing primary treatment choice for women aged 70 years or older with hormone receptor-positive early breast cancer. METHODS: Data from women diagnosed between 2002 and 2010 in the English Northern and Yorkshire and West Midlands regions were used to develop the model. Primary treatment options of surgery with adjuvant endocrine therapy or primary endocrine therapy were compared. Models predicting the hazard of breast cancer-specific mortality and hazard of other-cause mortality were combined to derive survival probabilities. The model was validated externally using data from the Eastern Cancer Registration and Information Centre. RESULTS: The model was developed using data from 23 842 women, and validated externally on a data set from 14 526 patients. The overall model calibration was good. At 2 and 5 years, predicted mortality from breast cancer and other causes differed from the observed rate by less than 1 per cent. At 5 years, there were slight overpredictions in breast cancer mortality (2629 predicted versus 2556 observed deaths; P = 0·142) and mortality from all causes (6399 versus 6320 respectively; P = 0·583). The discrepancy varied between subgroups. Model discrimination was 0·75 or above for all mortality measures. CONCLUSION: A prognostic model for older women with oestrogen receptor-positive early breast cancer was developed and validated in the present study. This forms a basis for an online decision support tool (https://agegap.shef.ac.uk/).


ANTECEDENTES: Se ha desarrollado y validado un modelo pronóstico utilizando datos del registro de cáncer. Ello ha permitido ofrecer una herramienta online para facilitar la toma de decisiones respecto a la elección del tratamiento inicial en mujeres mayores de 70 años con cáncer de mama precoz y receptores de hormonas positivos. MÉTODOS: Se incluyeron un total de 23.842 mujeres, diagnosticadas entre 2002 y 2010 en las regiones del Norte, Yorkshire y West Midlands inglesas que cumplieron con los criterios de inclusión. Se compararon dos opciones de tratamiento: cirugía primaria asociada a tratamiento endocrino adyuvante o tratamiento primario endocrino. Para estimar la probabilidad de supervivencia se combinaron modelos predictivos para el riesgo de mortalidad específica por cáncer de mama y para el riesgo de mortalidad por otras causas. Se realizó una validación externa con datos del Eastern Cancer Registration and Information Center (n = 14.526). RESULTADOS: La calibración global del modelo fue buena. A los 2 y 5 años, la mortalidad anticipada por cáncer de mama y por otras causas difería de la observada en menos del 1%. A los 5 años, hubo una ligera sobrevaloración de la predicción de mortalidad por cáncer de mama (prevista versus real: 2.629 versus 2.556, P = 0,78) y de la mortalidad por todas las causas (6.399 versus 6.320, P = 0,14). Esta discrepancia varió entre subgrupos. La capacidad discriminativa del modelo fue del 0,75 o superior para todas las medidas de mortalidad. CONCLUSIÓN: En este estudio, se desarrolló y validó un modelo pronóstico para mujeres mayores con cáncer de mama precoz positivo para receptores de estrógenos. Esta herramienta que facilita la toma de decisiones está disponible online (https://agegap.shef.ac.uk/).

RESUMO

BACKGROUND: Primary endocrine therapy is used as an alternative to surgery in up to 40 per cent of women with early breast cancer aged over 70 years in the UK. This study investigated the impact of surgery versus primary endocrine therapy on breast cancer-specific survival (BCSS) in older women. METHODS: Cancer registration data for 2002-2010 were obtained from two English regions. A retrospective analysis was performed for women with oestrogen receptor (ER)-positive disease, using statistical modelling to show the effect of treatment (surgery or primary endocrine therapy) and age and health status on BCSS. Missing data were handled using multiple imputation. RESULTS: Cancer registration data on 23 961 women were retrieved. After data preprocessing, 18 730 of 23 849 women (78·5 per cent) were identified as having ER-positive disease; of these, 10 087 (53·9 per cent) had surgery and 8643 (46·1 per cent) had primary endocrine therapy. BCSS was worse in the primary endocrine therapy group than in the surgical group (5-year BCSS rate 69·4 and 89·9 per cent respectively). This was true for all strata considered, although the difference was less in the cohort with the greatest degree of co-morbidity. For older, frailer patients the hazard of breast cancer death had less relative impact on overall survival. CONCLUSION: BCSS in older women with ER-positive disease is worse if surgery is omitted. This treatment choice may contribute to inferior cancer outcomes. Selection for surgery on the basis of predicted life expectancy may permit choice of women for whom surgery confers little benefit.

RESUMO

AIMS: Adjuvant chemotherapy is recommended as a treatment for women with high recurrence risk early breast cancer. Older women are less likely to receive chemotherapy than younger women. This study investigated the impact of chemotherapy on breast cancer-specific survival in women aged 70 + years using English registry data. MATERIALS AND METHODS: Cancer registration data were obtained from two English regions from 2002 to 2012 (n = 29 728). The impact of patient-level characteristics on the probability of receiving adjuvant chemotherapy was explored using logistic regression. Survival modelling was undertaken to show the effect of chemotherapy and age/health status on breast cancer-specific survival. Missing data were handled using multiple imputation. RESULTS: In total, 11 735 surgically treated early breast cancer patients were identified. Use of adjuvant chemotherapy has increased over time. Younger age at diagnosis, increased nodal involvement, tumour size and grade, oestrogen receptor-negative or human epidermal growth factor receptor 2-positive disease were all associated with increased probability of receiving chemotherapy. Chemotherapy was associated with a significant reduction in the hazard of breast cancer-specific mortality in women with high risk cancer, after adjusting for patient-level characteristics (hazard ratio 0.74, 95% confidence interval 0.67-0.81). DISCUSSION: Chemotherapy is associated with an improved breast cancer-specific survival in older women with early breast cancer at high risk of recurrence . Lower rates of chemotherapy use in older women may, therefore, contribute to inferior cancer outcomes. Decisions on potential benefits for individual patients should be made on the basis of life expectancy, treatment tolerance and patient preference.

RESUMO

5 min of tryptic digestion of purified rabbit skeletal alpha-actinin decreases by approximately 75% the ability of alpha-actinin to cross-link F-actin filaments as measured viscometrically at 27 degrees C, but has little effect on the sedimentation coefficient of alpha actinin at 20 degrees C or an alpha-actinin's ability to increase the Mg2+-modified ATPase activity and rate of turbidity increase of reconstituted actomyosin suspensions. Twenty to sixty min of trypsin treatment reduces the sedimentation coefficient of alpha-actinin and destroys much of alpha-actinin's ability to increase the MG2+-modified ATPase and rate of turbidity increase of reconstituted actomyosin suspensions. Therefore, the ability of alpha-actinin to increase the rate of in vitro measures of muscle contraction may not result directly from alpha-actinin's ability to cross-link F-actin filaments. Trypsin does not split alpha-actinin into large fragments as it does myosin. Previous studies have shown that 35 to 65% of total tryptic-susceptible peptide bonds in alpha-actinin are split after 60 min of incubation with trypsin and that 30% of these bonds split in 60 min are cleaved during the first 5 min in a rapid reaction. That splitting of this group of peptide bonds has little effect on the sedimentation coefficient of alpha-actinin indicates that these bonds are located in a region of the alpha-actinin molecule where noncovalent forces are strong enough to maintain conformation of the native alpha-actinin molecule even after these bonds have been split. This ostensible segregation of alpha-actinin's ability to cross-link F-actin filaments from its ability to increase rate of in vitro assays of contraction by tryptic digestion may suggest that alpha-actinin could have at least two different physiological roles: (1) to bind actin filaments to each other or to basal structures, and (2) to enhance the effectiveness of actin in supporting movement.

RESUMO

This literature review explores the reasons why comparatively few adult males with a history of childhood sexual abuse are seen by professionals for help with difficulties relating to that abuse. Two potential explanations are discounted as myths-that relatively few males are sexually abused, and that abuse has little effect on males. However, it is suggested that society (including professionals and the victims themselves) has given credence to these myths. Male victims are relatively unlikely to disclose their experience of childhood abuse, and (as a coping strategy) they deny the impact of sexual abuse on their lives. Professionals fail to hypothesise that their male clients may have been abused, and do not create the conditions that would enable males to talk about the abuse. Blumer's (1971) model of the social construction of problems is applied to account for these beliefs and behaviours on the part of victims and clinicians. It is argued that the childhood sexual abuse of males has not yet acquired legitimacy as a problem recognised by society, thus lagging behind the abuse of females. In short, the "evil' of childhood sexual abuse in the male population is not being seen or heard by clinicians, and is not being recognised or talked about by victims. Clinical implications are considered.

RESUMO

This paper details the results of a study of an undergraduate psychopharmacy rotation in an inpatient hospital setting and assesses its influence on pharmacy graduates careers in pharmacy. Significant features of the rotation include the students' participation in patient care activities and patient education about medications, as well as presentation of case histories. The students also took medication histories and revised patients' charts with the preceptor. Graduates of this program were sent questionnaires to assess their impressions of the rotation for quality of experience and for applicability to their pharmacy position. Ninety-four percent of the students responding worked as pharmacists and all reported dispensing psychoactive agents. Three-fourths of the respondents gave the program a positive rating for its influence on training in customer/patient relations and communications.

RESUMO

Behavior problems in 20 preschool children (13 boys, 7 girls) referred to a diagnostic nursery were assessed using parents' ratings. The patterns of behavior problems reported in 4- and 5-yr.-olds parallel those noted for older clinic-referred children (i.e., internalizing difficulties in girls, externalizing difficulties in boys). The most salient behavior problems for 3-yr.-olds involved aggression. Correlations between children's behavior problems and an index of parents' experienced stress were moderate (.44 to .64).

RESUMO

Factor-analyzed correlations among items of the Japanese Adolescent Reinforcement Survey Schedule by Japanese high school students (N = 939) and college students (N = 500) were compared to investigate the changes in reinforcers between mid- and late adolescence, gender differences, and the specific groupings of reinforcers which suggest certain interventions for either or both groups of adolescents. The factor analysis yielded ten interpretable factors in both groups. These factors were similar and did not suggest a dramatic shift in reinforcers between mid- and late adolescence. Items related to heterosexual activities and antisocial behaviors were rated as more pleasurable by males and items related to interpersonal relationships and academic activities were rated as more pleasurable by females. Since both groups of students attach high reinforcement value to interpersonal interaction with peers and family members, interventions focusing on social skills development might be popular and well attended.
