Whole breast and regional nodal irradiation in prone versus supine position in left sided breast cancer

Background: Prone whole breast irradiation (WBI) leads to reduced heart and lung doses in breast cancer patients receiving adjuvant radiotherapy. In this feasibility trial, we investigated the prone position for whole breast + lymph node irradiation (WB + LNI). Methods: A new support device was developed for optimal target coverage, on which patients are positioned in a position resembling a phase from the crawl swimming technique (prone crawl position). Five left sided breast cancer patients were included and simulated in supine and prone position. For each patient, a treatment plan was made in prone and supine position for WB + LNI to the whole axilla and the unoperated part of the axilla. Patients served as their own controls for comparing dosimetry of target volumes and organs at risk (OAR) in prone versus in supine position. Results: Target volume coverage differed only slightly between prone and supine position. Doses were significantly reduced (P < 0.05) in prone position for ipsilateral lung (Dmean, D2, V5, V10, V20, V30), contralateral lung (Dmean, D2), contralateral breast (Dmean, D2 and for total axillary WB + LNI also V5), thyroid (Dmean, D2, V5, V10, V20, V30), oesophagus (Dmean and for partial axillary WB + LNI also D2 and V5), skin (D2 and for partial axillary WB + LNI V105 and V107). There were no significant differences for heart and humeral head doses. Conclusions: Prone crawl position in WB + LNI allows for good breast and nodal target coverage with better sparing of ipsilateral lung, thyroid, contralateral breast, contralateral lung and oesophagus when compared to supine position. There is no difference in heart and humeral head doses

EMAS recommendations for conditions in the workplace for menopausal women

Women form a large part of many workforces throughout Europe. Many will be working throughout their menopausal years. Whilst the menopause may cause no significant problems for some, for others it is known to present considerable difficulties in both their personal and working lives. During the menopausal transition women report that fatigue and difficulties with memory and concentration can have a negative impact on their working lives. Furthermore, hot flushes can be a source of embarrassment and distress. Some consider that these symptoms can impact on their performance. Greater awareness among employers, together with sensitive and flexible management can be helpful for women at this time. Particular strategies might include: fostering a culture whereby employees feel comfortable disclosing health problems, allowing flexible working, reducing sources of work-related stress, providing easy access to cold drinking water and toilets, and reviewing workplace temperature and ventilation

Haptoglobin polymorphism in patients with preeclampsia

Background: Haptoglobin (Hp) polymorphism has been associated with blood pressure regulation and essential hypertension. We investigated Hp polymorphism in patients with preeclampsia. Methods: A total of 60 Caucasian women with preeclampsia were prospectively followed from hospital admission until delivery. Serum Hp phenotypes 1-1, 2-1, and 2-2 were determined by starch gel electrophoresis and compared with those in 200 normotensive controls of the same geographic and ethnic origin. Blood pressure and laboratory markers (serum uric acid, alanine aminotransferase, aspartate aminotransferase, platelet count, and 24-h proteinuria) were compared according to Hp phenotypes of preeclamptic women. Results: We found a higher Hp1allele frequency in the preeclamptic group than in normotensive controls (0.517 vs. 0.400, p Conclusions: The Hp1 allele frequency was higher among preeclamptic patients and the Hp 1-1 phenotype was associated with more severe hypertension and proteinuria

Comparing raloxifene with continuous combined estrogen-progestin therapy in postmenopausal women: Review of Euralox I

OBJECTIVES: To review the main findings of the Euralox 1 study - a multicentre, randomised, double-blind study conducted in 1008 healthy postmenopausal women allocated to raloxifene (n = 495) or continuous combined estrogen-progestin therapy (ccEPT; n = 513) for 6 months -- and provide an overview of the risks and benefits of raloxifene and ccEPT. METHODS: A review is provided of previously published findings on uterine safety (bleeding rates and changes in endometrial thickness and uterine volume), gynaecological adjudication, cardiovascular risk (lipids, fibrinogen), adverse events, compliance, treatment satisfaction and quality of life. New data on biochemical markers of bone turnover (serum N-telopeptides and C-terminal telopeptides of type I collagen; NTX and CTX) assessed before and after 6 months' treatment are presented. RESULTS: Raloxifene caused less uterine bleeding than ccEPT and, unlike ccEPT, did not alter endometrial thickness or uterine volume. Serum CTX and NTX levels were reduced in both treatment groups, but the reduction was significantly greater with ccEPT. The two treatments had differential effects on lipids and fibrinogen levels; raloxifene had more favourable effects on serum HDL, the LDL/HDL ratio, and plasma fibrinogen. Raloxifene was associated with fewer adverse events or discontinuations, and this was associated with higher treatment satisfaction and better self-reported compliance. CONCLUSIONS: The clinical risk-benefit profile of raloxifene derived from the intermediate endpoints of this study suggests that it may be a better alternative to ccEPT for preventing long-term postmenopausal health risks in healthy postmenopausal women who are not suffering from vasomotor symptoms
