The development and application of high-speed digital switching trees for regular arithmetic arrays.

This work represents the author\u27s contributions to a joint effort into the development of switching tree architectures. The work concentrates on concepts of CMOS design and lay-out stressing the optimization of parasitic and interconnect capacitance to increase circuit performance. Practical design techniques are discussed with regards to constructing pad frames and power distribution networks. These concepts are then applied to a set of three cells which trace the development of the switching tree cell. The clocking schemes, ROM architectures and general structure of each cell are discussed in detail. Finally, a set of standard cells is constructed using the switching tree structure, in 3$\mu$ CMOS technology. SPICE simulations indicate that cells performing 3-bit binary addition in one clock cycle are capable of functioning at clock speeds of up to 50 Mhz. Test results confirm the functionality of the cells up to the maximum speed of the Input/Output (I/O)pads, which is approximately 40 Mhz. Due to current I/O pad speed limitations, a set of ECL Compatible I/O pads is developed for use as part of the standard cell library. Simulation results indicate that the pads are capable of operating at speeds above 100 Mhz. Test results confirm the pads operation up to 65 Mhz, which is the maximum speed available from the test equipment. Based on the test results, it is estimated that the maximum speed of the 3$\mu$ ECL Compatible I/O pads is approximately 80 Mhz.Dept. of Electrical and Computer Engineering.

Risk of cancer after assisted reproduction: a review of the available evidences and guidance to fertility counselors

Infertile women requiring ovarian stimulation and assisted reproduction techniques (ART) are faced with difficult issues. The fear that using hormones could increase their risk of cancer is the most significant. One of the main challenges for assessing cancer risk after ART is the difficulty to separate it from the underlying condition of infertility per se. The delay or the inability to achieve a pregnancy is an important risk factor for breast, endometrial and ovarian cancer. We analyzed the current literature on the topic

Vulvovaginal atrophy (VVA) in breast cancer survivors (BCS) is still an unmet medical need: results of an Italian Delphi Panel

Abstract: Purpose: VVA is a common disease, with approximately 50% of all postmenopausal women having related symptoms. VVA has a significant impact on the personal and sexual lives and on many aspects of women\u2019s self-esteem and emotional well-being. It is particularly frequent and severe in patients treated for BC, where it originates significant economic and social costs. Given the lack of published evidence on this subject, a Delphi Panel was carried out to evaluate:The epidemiology of VVA and of its risk-factors/comorbidities in ItalyThe present standard of care and unmet medical needsThe comparison between recent US epidemiological data and the Italian situationThe health resources used in VVA BC The burden of illnessDespite the considerable negative impact on quality of life, a disparity between the high prevalence of this condition and the infrequent clinical diagnosis is documented in medical practice and in surveys. This inaccuracy is thought to be primarily a consequence of patients\u2019 unwillingness and/or reluctance to report symptoms in the clinical setting and of health-care professional\u2019s difficulty in approaching this sensitive topic during routine consultations. Methods: A Delphi Panel methodology was used: a first round of written questionnaires, followed by a plenary meeting with a facilitator and by two additional rounds of telephone interviews. Results: The prevalence of the condition in Italy can be estimated in 115,000 cases out of 380,000 BC survivors. The Panel confirmed that the epidemiological findings of a recent pharmacoeconomic analysis of a US claims database can be applied to Italian patient population. The Panel confirmed also an estimate of 4.25 additional cases/100/yr of UTI (urinary tract infection) in VVA BC patients (vs. a non-VVA-matched population), of 3.68 additional cases of vulvovaginitis, of 6.97 cases of climacteric symptoms, and of 3.64 cases of bone and joint disorders. As far as the resource use is concerned, in the VVA BC populations, 33.4 additional gynecological visits/100/year can be expected, along with 22.8 additional cancer screenings, 7.07 additional outpatient visits and 5.04 screenings for HPV. Conclusions: Even in Italy, a diagnosis of VVA, especially in a BC population, is associated with a relevant increase in the burden of illness and social costs, compared to a control population matched for age without VVA. This is due essentially to an increase in comorbidities and resource utilization with the consequence that an adequate treatment could reduce the impact of the condition

Biology, staging, and treatment of breast cancer during pregnancy: reassessing the evidences

Breast cancer is one of the most frequently diagnosed malignancies during pregnancy. Here, we review the management of women with breast cancer during pregnancy (BCP), focusing on biology, diagnosis and staging, local and systemic treatments, obstetric care and long-term follow-up of children with prenatal exposure to anticancer treatments

Antiblastic Treatment, for Solid Tumors, during Pregnancy: A Crucial Decision:

Cancer is the second leading cause of death during the reproductive years complicating between 0.02% and 0.1% of pregnancies. The incidence is expected to rise with the increase in age of childbearing. The most common types of pregnancy-associated cancers are: cervical cancer, breast cancer, malignant melanoma, Hodgkin's lymphoma, non-Hodgkin's lymphoma and ovarian cancer. The relatively rare occurrence of pregnancy-associated cancer precludes conducting large, prospective studies to examine diagnostic, management and outcome issues. The treatment of pregnancy-associated cancer is complex since it may be associated with adverse fatal effects. In pregnant patients diagnosed with cancer during the first trimester, treatment with multidrug anti-cancer chemotherapy is associated with an increased risk of congenital malformations, spontaneous abortions or fetal death, and therefore, should follow a strong recommendation for pregnancy termination. Second and third trimester exposure is not associated with teratogenic effect but increases the risk of intrauterine growth retardation and low birth weight. There are no sufficient data regarding the teratogenicity of most cytotoxic drugs. Almost all chemotherapeutic agents were found to be teratogenic in animals and for some drugs only experimental data exist. Moreover, no pharmacokinetic studies have been conducted in pregnant women receiving chemotherapy in order to understand whether pregnant women should be treated with different doses of chemotherapy. This article reviews the available data regarding the different aspects of the treatment of cancer during pregnancy

Use of complementary and alternative medicine (CAM) in cancer patients. An italian multicenter survey

INTRODUCTION: Complementary and Alternative Medicine (CAM) include a wide range of products (herbs, vitamins, minerals, and probiotics) and medical practices, developed outside of the mainstream Western medicine. Patients with cancer are more likely to resort to CAM first or then in their disease history; the potential side effects as well as the costs of such practices are largely underestimated. PATIENTS AND METHOD: We conducted a descriptive survey in five Italian hospitals involving 468 patients with different malignancies. The survey consisted of a forty-two question questionnaire, patients were eligible if they were Italian-speaking and receiving an anticancer treatment at the time of the survey or had received an anticancer treatment no more than three years before participating in the survey. RESULTS: Of our patients, 48.9% said they use or have recently used CAM. The univariate analysis showed that female gender, high education, receiving treatment in a highly specialized institute and receiving chemotherapy are associated with CAM use; at the multivariate analysis high education (Odds Ratio, (OR): 1.96 95% Confidence Interval, CI, 1.27-3.05) and receiving treatment in a specialized cancer center (OR: 2.75 95% CI, 1.53-4.94) were confirmed as risk factors for CAM use. CONCLUSION: Roughly half of our patients receiving treatment for cancer use CAM. It is necessary that health professional explore the use of CAM with their cancer patients, educate them about potentially beneficial therapies in light of the limited available evidence of effectiveness, and work towards an integrated model of health-care provision

SRM・CRMの観点から考察する商社営業のコンピテンシー

Stem cells have captured the imagination of the general public by their potential as new therapeutic tools in the fight against degenerative diseases. This potential is based on their capability for self-renewal and at the same time for producing progenitor cells that will eventually provide the building blocks for tissue and organ regeneration. These processes are carefully orchestrated in the organism by means of a series of molecular cues. An emerging molecule which is responsible for some of these physiological responses is adrenomedullin, a 52-amino acid regulatory peptide which increases proliferation and regulates cell fate of stem cells of different origins. Adrenomedullin binds to specific membrane receptors in stem cells and induces several intracellular pathways such as those involving cAMP, Akt, or MAPK. Regulation of adrenomedullin levels may help in directing the growth and differentiation of stem cells for applications (e.g., cell therapy) both in vitro and in vivo. © 2012 Elsevier Inc.Peer Reviewe
