[THE EFFECTS OF HORMONAL REPLACEMENT THERAPY (HRT) ON MAMMOGRAPHIC BREAST DENSITY AND ABNORMAL MAMMOGRAMS PROMPTING FURTHER INVESTIGATION].

Aims: The purpose of this study was to portray and analyze the inter-relationship between the use of HRT, mammographic breast density and the finding of any mammographic abnormality that prompted further investigation such as core needle biopsy or additional imaging testing, while controlling for obstetric and relevant demographic data.

Background: Mammographic breast density has been associated with higher risk of breast cancer and decrease in its sensitivity, while hormonal replacement therapy (HRT) in turn, has been implicated in increasing mammographic density and is considered a risk factor for breast cancer by itself. The inter-relationship between HRT, breast density and any mammographic or sonographic finding requiring further investigation has not been fully investigated.

Diverticulitis: does age matter?

Objective: Acute diverticulitis has been traditionally associated with worse outcome in young patients, indicating a more aggressive surgical approach is required for them. The aim of this study was to assess whether acute diverticulitis was more virulent in young patients.

Methods: A retrospective, cross-sectional study included all patients who were admitted for a first episode of acute diverticulitis between January 2004 and December 2013.

Mammographic Breast Density as a Predictor of Radiological Findings Requiring Further Investigation.

Background: High density breast mammography has been associated with a greater risk for breast cancer and an increased likelihood of false negative results.

Objectives: To assess whether the degree of mammographic breast density correlates with increased risk for the presence of radiographic findings requiring further histological investigation.

Methods: Included in the study were 2760 consecutive screening mammograms performed in a large volume, early detection mammography unit.

Correlation between visual acuity and cognitive functions.

A possible association between visual acuity (VA) and dementia was investigated in 2716 subjects who were aged between 53 and 102 at first visit and had varying degrees of dementia. Better VA was found to be significantly correlated with a lower dementia level (person coefficient range 0.146-0.

Erythropoietin treatment is associated with an augmented immune response to the influenza vaccine in hematologic patients.

The objective of this study was to examine whether treatment with recombinant human erythropoietin (rHuEPO), previously found to be associated with a positive effect on cell-mediated immunity and humoral immunity (hepatitis B vaccine), is associated with an improved response to the seasonal influenza (flu) vaccine. Three groups received flu vaccine: healthy controls, hematologic patients not treated with rHuEPO ("No EPO" group), and hematologic patients receiving rHuEPO for their anemia ("EPO" group). Anti-flu Ab titer was measured (complement fixation test) from blood samples drawn before and approximately 3-4 weeks, 7-8 weeks and 4 months after vaccination.

Identification of children's gender and age by listeners.

Objectives: Voice carries abundant information about the speaker. This acoustic information changes throughout life. Although the ability of identifying audible cues on a speaker's gender and age is considered an intuitive task, little is known about the ability to identify and decipher this perceptual information.

The effects of group 1 versus group 2 carbapenems on imipenem-resistant Pseudomonas aeruginosa: an ecological study.

Use of the group 2 carbapenems, imipenem and meropenem, may lead to emergence of Pseudomonas aeruginosa resistance. The group 1 carbapenem ertapenem has limited activity against P. aeruginosa and is not associated with imipenem-resistant P.

Inflammatory mediators in breast cancer: coordinated expression of TNFα & IL-1β with CCL2 & CCL5 and effects on epithelial-to-mesenchymal transition.

Background: The inflammatory chemokines CCL2 (MCP-1) & CCL5 (RANTES) and the inflammatory cytokines TNFα & IL-1β were shown to contribute to breast cancer development and metastasis. In this study, we wished to determine whether there are associations between these factors along stages of breast cancer progression, and to identify the possible implications of these factors to disease course.

Methods: The expression of CCL2, CCL5, TNFα and IL-1β was determined by immunohistochemistry in patients diagnosed with: (1) Benign breast disorders (=healthy individuals); (2) Ductal Carcinoma In Situ (DCIS); (3) Invasive Ducal Carcinoma without relapse (IDC-no-relapse); (4) IDC-with-relapse.

Purpose: We sought to determine the level of involvement of oncologists in bereavement rituals after a patient dies.

Subjects And Methods: Members of the Israeli Society for Clinical Oncology and Radiation Therapy (ISCORT) were surveyed. The survey instrument consisted of questions regarding participation in bereavement rituals for patients in general and those with whom the oncologist had a special bond.

Long-term cryostorage of sperm in a human sperm bank does not damage progressive motility concentration.

Background: The use of quarantined cryopreserved semen is mandatory in donor insemination programs. Whether sperm cells can survive and retain their ability to fertilize after long-term storage remains a controversial issue. The objective of this study was to determine the effect of the duration of cryostorage in liquid nitrogen on the sperm cells' progressive motility concentration (PMC) in a large study group.

[Laparoscopic colon and rectal surgery--after ten years and 350 operations].

Background: Within a decade since laparoscopy was used in cholecystectomy it has become the preferred approach in many abdominal procedures. Laparoscopic colon and rectal surgery has not yet been adopted by the majority of surgeons, due to technical complexity and reservation regarding its oncological safety. As data and experience accumulate, this attitude is gradually changing.

Birth control pills and nonprofessional voice: acoustic analyses.

Development of a cancer-specific anterior skull base quality-of-life questionnaire.

Object: The goal of this study was to develop a disease-specific, multidimensional quality of life (QOL) assessment instrument for patients undergoing surgical extirpation of anterior skull base tumors.

Methods: This investigation included 35 patients who had been surgically treated for more than 3 months before the study was begun. Relevant QOL questions were generated from a review of the literature and interviews with health professionals, patients, and their caregivers.

Reduced medial olivocochlear bundle system function in children with auditory processing disorders.

A common complaint of children with auditory processing disorders (APD) is difficulty in understanding speech in the presence of background noise. Evidence from animal and human studies has suggested that the medial olivocochlear bundle (MOCB) may play a role in hearing in noise. The MOCB function can be evaluated by the suppression effect of the transient evoked otoacoustic emissions (TEOAE) in response to contralateral acoustic stimulation (CAS).
