The effects of dietary changes on bone markers in postmenopausal vertebral osteopenia.

Background & Aims: Nutrition is one of the most important environmental factors affecting the formation of osteopenia. The purpose of this study was to investigate the effects of dietary changes on bone formation and bone resorption markers of postmenopausal women with vertebral osteopenia.

Supplementation of docosahexaenoic acid (DHA) / Eicosapentaenoic acid (EPA) in a ratio of 1/1.3 during the last trimester of pregnancy results in EPA accumulation in cord blood.

Omega-3 fatty acids (n-3 FA), specifically DHA, are associated with fetal growth and development. We aimed to determine the levels of DHA and EPA in cord serum after n-3 FA supplementation during the last trimester of pregnancy. Among 55 women, 23 were administered daily one capsule of n-3 FA supplement, involving DHA/EPA in a ratio of 1/1.

A Cross-Sectional Study: Nutritional Polyamines in Frequently Consumed Foods of the Turkish Population.

Putrescine, spermidine and spermine are the most abundant polycationic natural amines found in nearly all organisms. They are involved in regulation of gene expression, translation, cell proliferation and differentiation. They can be supplied by the endogenous synthesis inside the cell or by the intake from exogenous sources.

Clothing preference affects vitamin D status of young women.

Vitamin D deficiency is associated with several chronic diseases, which include cardiovascular, autoimmune diseases, and cancer. Several factors such as exposure to sunlight, skin color, dietary habits, and cultural factors affect serum vitamin D levels. We hypothesized that serum vitamin D levels in young women are associated with clothing styles and investigated this via a cross-sectional study that included 100 female students at Istanbul Medipol University.

The great mimicker: zona zoster at the mastectomy site causing contralateral intramammary lymph node enlargement.

Zona zoster is rarely observed in patients with malignancy; when present, it follows a dermatomal fashion. Involvement of widely separated regions is very rare. Hereby, zona zoster causing enlarged intramammary lymph nodes (IMLN) in the opposite breast is reported for the first time in literature.

Lycopene in the prevention of gastrointestinal toxicity of radiotherapy.

We conducted a study to investigate if lycopene could reduce gastrointestinal toxicity of abdominal and pelvic radiation in Wistar albino rats. Animals received either a control diet (Group 1), lycopene-supplemented diet (Group 2), control diet and radiation (Group 3), and lycopene-supplemented diet plus radiation (Group 4). In Groups 2 and 4, the rats received 5 mg/kg/day lycopene for 10 days.

Optimisation techniques in vaginal cuff brachytherapy.

The aim of this study was to explore whether an in-house dosimetry protocol and optimisation method are able to produce a homogeneous dose distribution in the target volume, and how often optimisation is required in vaginal cuff brachytherapy. Treatment planning was carried out for 109 fractions in 33 patients who underwent high dose rate iridium-192 (Ir(192)) brachytherapy using Fletcher ovoids. Dose prescription and normalisation were performed to catheter-oriented lateral dose points (dps) within a range of 90-110% of the prescribed dose.

Changes in applicator positions and dose distribution between high dose rate brachytherapy fractions in cervix carcinoma patients receiving definitive radiotherapy.

This study examines the change of applicator geometry and its effect on rectal/rectum (R) and bladder (B) doses, and obtained radiobiological equivalent doses (RED), between each high dose rate (HDR) brachytherapy (BT) fraction in cervical carcinoma patients. BT using a tandem (T) and two ovoids (O) is included, and any discrepancies in applicator positions among the fractions were calculated. Whether the change of applicator position had an effect on the calculated R and B doses was analysed.

The tolerability and efficacy of the continuous infusion of cisplatin during radiotherapy was studied by tumour response, survival and pelvic control, in carcinoma of the cervix. 44 patients with stage IIB-IIIB cervical carcinoma were prospectively randomized into two groups: radiation alone (control group) versus radiation plus cisplatin (study group). While there was no significant difference in diarrhoea and urinary complication scores, emesis and appetite changes were significantly greater in the study group.

The aim of this study was to determine the role of technetium-99m methoxyisobutyl isonitrile (99mTc-MIBI) scintigraphy in the evaluation of recurrence and metastases in breast cancer patients with mastectomy and/or radiotherapy. A prospective study was designed to assess the accuracy of 99mTc-MIBI scintigraphy in 36 patients (mean age 49 years) with suspected recurrent breast cancer. The scintigraphic studies were correlated with radiological findings and/or with histopathology.

The role of lung perfusion imaging in predicting the direction of radiation-induced changes in pulmonary function tests.

Background: The aim of this study was to determine whether preradiation (pre-RT) single photon emission computed tomography (SPECT) lung perfusion scans can be used to predict RT-induced changes in pulmonary function tests (PFTs).

Methods: Ninety-four patients irradiated for thoracic tumors had pre-RT SPECT lung perfusion scans. The presence of SPECT hypoperfusion distal to a central mediastinal tumor was qualitatively assessed visually without knowledge of PFT changes.
