1441. Factors influencing rehabilitation in patients with head and neck cancerIrena Hočevar-Boltežar, Alojz Šmid, Miha Žargi, Avgust Župevc, Igor Fajdiga, Janez Fischinger, Ana Jarc, 2000, izvirni znanstveni članek Povzetek: Purpose. The purpose of the prospective study was to identify the factors adversely influencing the post-treatment rehabilitation in patients with head and neck cancer. Patients and methods. One hundred and ten patients with oral cavity, pharyngeal and laryngeal cancer were examined before surgical treatment in order to find unfavorable factors: hearing loss, defective teeth,impaired pulmonary function, and speech disorders. The patients evaluated the success of their rehabilitation 12 months after the treatment. The influence of possible unfavorable factors, tumor site, and type of surgeryon speech, swallowing and reintegration competence was determinated. Results. The site of the tumor and the type of surgery did not influence the quality of rehabilitation in general. Defective teeth influenced the ability of swallowing but not the speech. Hearing loss impaired the patient's reintegration in their home environment. Impaired pulmonary function did not affect patient's speech. Speech was the poorest in laryngectomized patients. However, about two thirds of the patients were satisfied with their capabilityof speech, swallowing and their rehabilitation in general. Conclusions. Early identification of unfavorable factors, and individually planned rehabilitation can ensure a suitable quality of life for patients thathave undergone surgery for head and neck cancer.

1442. Do we need axillary dissection in early breast cancer?Tanja Čufer, 2000, objavljeni znanstveni prispevek na konferenci Povzetek: Background. In the existing paradigm of the invasive breast cancer, the treatment with the axillary lymphnode dissection (ALND) and histologic stagingof the axilla, which is associated with a substantial morbidity, is considered necessary for the treatment decision and local control of disease. However paradigms are changing and, since primary tumor characteristics are increasingly used for treatment decision and since there is a trend towards the broad application of preoperative chemotherapy, ALND is less and less important for the treatment planning. In a small subgroup of patients in whom the information on nodal status is still important it can be obtained accurately by the sentinel lymph node biopsy. For good local control of the disease, ALND can be replaced with irradiation of the axilla with substantially lesser morbidity. Conclusions. Abandoning ALND together with breast conserving surgery is one of the major steps towards less mutilating surgery leading to a better quality of life of breast cancer patients at the end of this millennium.

1447. Alternative alkali activators based on waste bottle glass and waste cathode-ray tube glassKatja Koenig, Katja Traven, Vilma Ducman, 2021, objavljeni znanstveni prispevek na konferenci Povzetek: Alkali-activated binders are an environmentally friendly alternative to Portland cement, particularly when locally-available raw materials are used. It is well known that alkali activation with a sodium silicate activator generates a hardened binder with higher compressive strength than a binder hardened with sodium hydroxide. As the alkali-silicate activators are produced through energy extensive processes, and their use can significantly increase the carbon footprint of the final products, it is of great significance to develop alternative alkaline activators based on locally-available waste materials. This article assesses the potential to apply waste bottle glass and waste cathode-ray tube (CRT) glass to synthesise alternative alkali activators by the hydrothermal method. Inductively coupled plasma-optical emission spectrometry (ICP-OES) was used to determine silicon and aluminium content in the alternative activators. The influence of dissolution process parameters (time, temperature, particle size) on the concentrations of silicon and aluminium in the alternative activators was investigated. The alternative activators with silicon concentration up to 19 g/L and aluminium concentration up to 0.9 g/L were prepared at T = 120 °C and boiling time 24 h. The alternative alkali activators and, for comparison, also commercial sodium silicate were used in the alkali activation of fly ash powder. The formed pastes were cured at 70 °C for 72 h. Mechanical strength measurements indicated that alkali activation of fly ash with the optimal alternative activator yielded hardened paste with compressive strength of 33 MPa. However, the compressive strength of hardened paste prepared from fly ash and commercial sodium silicate reached 70 MPa. Part of this difference can be ascribed to the lower density of hardened pastes prepared with alternative activators.
