Patterns of recurrence of early breast cancer according to estrogen receptor status: a therapeutic target for a quarter of a century

The current therapeutic strategy in breast cancer is to identify a target, such as estrogen receptor (ER) status, for tailoring treatments. We investigated the patterns of recurrence with respect to ER status for patients treated in two randomized trials with 25 years' median follow-up. In the ER-negative subpopulations most breast cancer events occurred within the first 5-7 years after randomization, while in the ER-positive subpopulations breast cancer events were spread through 10 years. In the ER-positive subpopulation, 1 year endocrine treatment alone significantly prolonged disease-free survival (DFS) with no additional benefit observed by adding 1 year of chemotherapy. In the small ER-negative subpopulation chemo-endocrine therapy had a significantly better DFS than endocrine alone or no treatment. Despite small numbers of patients, "old-fashioned" treatments, and competing causes of treatment failure, the value of ER status as a target for response to adjuvant treatment is evident through prolonged follow-up.

Aerological observations in the Tropics in the Early Twentieth Century

In the first decades of the 20th century, aerological observations were for the first time performed in tropical regions. One of the most prominent endeavours in this respect was ARTHUR BERSON’s aerological expedition to East Africa. Although the main target was the East African monsoon circulation, the expedition provided also other insights that profoundly changed meteorology and climatology. BERSON observed that the tropical tropopause was much higher and colder than that over midlatitudes. Moreover, westerly winds were observed in the lower stratosphere, apparently contradicting the high-altitude equatorial easterly winds that were known since the Krakatoa eruption (‘‘Krakatoa easterlies’’). The puzzle was only resolved five decades later with the discovery of the Quasi-Biennial Oscillation (QBO). In this paper we briefly summarize the expedition of BERSON and review the results in a historical context and in the light of the current research. In the second part of the paper we re-visit BERSON’s early aerological observations, which we have digitized. We compare the observed wind profiles with corresponding profiles extracted from the ‘‘Twentieth Century Reanalysis’’, which provides global three-dimensional weather information back to 1871 based on an assimilation of sea-level and surface pressure data. The comparison shows a good agreement at the coast but less good agreement further inland, at the shore of Lake Victoria, where the circulation is more complex. These results demonstrate that BERSON’s observations are still valuable today as input to current reanalysis systems or for their validation.

Critical Analysis of Bladder Sparing with Trimodal Therapy in Muscle-invasive Bladder Cancer: A Systematic Review.

CONTEXT Aims of bladder preservation in muscle-invasive bladder cancer (MIBC) are to offer a quality-of-life advantage and avoid potential morbidity or mortality of radical cystectomy (RC) without compromising oncologic outcomes. Because of the lack of a completed randomised controlled trial, oncologic equivalence of bladder preservation modality treatments compared with RC remains unknown. OBJECTIVE This systematic review sought to assess the modern bladder-preservation treatment modalities, focusing on trimodal therapy (TMT) in MIBC. EVIDENCE ACQUISITION A systematic literature search in the PubMed and Cochrane databases was performed from 1980 to July 2013. EVIDENCE SYNTHESIS Optimal bladder-preservation treatment includes a safe transurethral resection of the bladder tumour as complete as possible followed by radiation therapy (RT) with concurrent radiosensitising chemotherapy. A standard radiation schedule includes external-beam RT to the bladder and limited pelvic lymph nodes to an initial dose of 40Gy, with a boost to the whole bladder to 54Gy and a further tumour boost to a total dose of 64-65Gy. Radiosensitising chemotherapy with phase 3 trial evidence in support exists for cisplatin and mitomycin C plus 5-fluorouracil. A cystoscopic assessment with systematic rebiopsy should be performed at TMT completion or early after TMT induction. Thus, nonresponders are identified early to promptly offer salvage RC. The 5-yr cancer-specific survival and overall survival rates range from 50% to 82% and from 36% to 74%, respectively, with salvage cystectomy rates of 25-30%. There are no definitive data to support the benefit of using of neoadjuvant or adjuvant chemotherapy. Critical to good outcomes is proper patient selection. The best cancers eligible for bladder preservation are those with low-volume T2 disease without hydronephrosis or extensive carcinoma in situ. CONCLUSIONS A growing body of accumulated data suggests that bladder preservation with TMT leads to acceptable outcomes and therefore may be considered a reasonable treatment option in well-selected patients. PATIENT SUMMARY Treatment based on a combination of resection, chemotherapy, and radiotherapy as bladder-sparing strategies may be considered as a reasonable treatment option in properly selected patients.

Family Stability and Childhood Behavioral Outcomes: A Critical Review of the Literature

As the definition of what is considered a family changes in our society, the family unit itself continues to undergo changes. These changes can sometimes lead to decreased stability within the family unit. One of the greatest challenges facing those researching this phenomenon is the lack of consistency within the existing body of research surrounding what familial instability actually is (the definition). This critical review of the literature examines the current body of literature in order to identify what is known about family stability and its impact on adolescent behavior, as well as what gaps currently exist. This review focuses on definitions of family stability, current factors surrounding the stability of the family unit, and addresses the implications that the current body of literature presents.

Religion and the Senses in Early Modern Europe

Sensation is the subject of a burgeoning field in the humanities. This volume examines its role in the religious changes and transformations of early modern Europe. Sensation was not only central to the doctrinal disputes of the Reformation, but also critical in shaping new or reformed devotional practices. From this vantage point the book explores the intersections between the world of religion and the spheres of art, music, and literature; food and smell; sacred things and spaces; ritual and community; science and medicine. Deployed in varying, often contested ways, the senses were essential pathways to the sacred. They permitted knowledge of the divine and the universe, triggered affective responses, shaped holy environments, and served to heal, guide, or discipline body and soul.
