Contributing Determinants to Hearing Loss in Elderly Men and Women: Results from the Population-Based Rotterdam Study

To contribute to a better understanding of the etiology in age-related hearing loss, we carried out a cross-sectional study of 3,315 participants (aged 52-99 years) in the Rotterdam Study, to analyze both low- and high-frequency hearing loss in men and women. Hearing thresholds with pure-tone audiometry were obtained, and other detailed information on a large number of possible determinants was collected. Hearing loss was associated with age, education, systolic blood pressure, diabetes mellitus, body mass index, smoking and alcohol consumption (inverse correlation). Remarkably, different associations were found for low- and high-frequency loss, as well as between men and women, suggesting that different mechanisms are involved in the etiology of age-related hearing loss

Androgen deprivation therapy for androgen receptor-positive advanced salivary duct carcinoma:A nationwide case series of 35 patients in The Netherlands

Background: Salivary duct carcinoma, an aggressive subtype of salivary gland cancer, is mostly androgen receptor-positive. Only limited data are available on androgen deprivation therapy (ADT). Methods: Patients with advanced androgen receptor-positive salivary duct carcinoma treated with first-line ADT were retrospectively evaluated for clinical benefit (ie, partial response [PR] and stable disease, progression-free survival [PFS] and overall survival [OS]). The OS was compared with patients with advanced salivary duct carcinoma who received best supportive care. Results: Thirty-four of 35 patients who were ADT-treated were evaluable: 6 patients had a PR (18%) and 11 had stable disease (32%) leading to a clinical benefit ratio of 50%. The median PFS for the ADT-treated patients was 4 months and the median duration of clinical benefit was 11 months. The median OS was 17 months versus 5 months in 43 patients receiving best supportive care (P=.02). Conclusion: We recommend ADT in advanced androgen receptor-positive salivary duct carcinoma given its response and clinical benefit

Advancing interdisciplinary research in head and neck cancer through a multicenter longitudinal prospective cohort study: The NETherlands QUality of life and BIomedical Cohort (NET-QUBIC) data warehouse and biobank

Background: Worldwide, over 500,000 people are diagnosed with head and neck cancer each year, a disease with major impact on life expectancy and quality of life. The purpose of the Netherlands Quality of life and Biomedical Cohort study (NET-QUBIC) is to advance interdisciplinary research that aims to optimize diagnosis, treatment, and supportive care for head and neck cancer patients and their informal caregivers. Methods: Using an extensive assessment protocol (electronic clinical record form, patient reported outcome measures and fieldwork (interviews and physical tests)), clinical data and data on quality of life, demographic and personal factors, psychosocial (depression, anxiety, fatigue, pain, sleep, mental adjustment to cancer, posttraumatic stress), physical (speech, swallowing, oral function, malnutrition, physical fitness, neurocognitive function, sexual function), lifestyle (physical activity, nutrition, smoking, alcohol, drugs), and social factors (social function, social support, work, health care use, and costs) are collected and stored in the data warehouse. A longitudinal biobank is built with tumor tissue, blood and blood components, saliva samples, and oral rinses. An infrastructure for fieldwork and laboratory protocols is esta

Apoptin Enhances Radiation-Induced Cell Death in Poorly Responding Head and Neck Squamous Cell Carcinoma Cells

Treatment of head and neck cancers is still rather poor and worldwide new treatment options are sought. Sensitizing radioresistant tumours by combining irradiation with other therapeutics to induce apoptosis are widely investigated. We examined whether chicken anaemia virus-derived apoptin protein would have a beneficial effect on irradiation of radiosensitive SCC61 and radioresistant SQD9 human head and neck squamous carcinoma cell lines. In both cell lines, concurrent exposure to irradiation and apoptin resulted in analysed mitochondrial cytochrome c release and in cleavage of caspase-3, whereas irradiation alone of SQD9 cells under identical conditions did not. Moreover, in comparison with the irradiation, only the synchronized treatment of apoptin and irradiation resulted in increased cell death in especially the radioresistant SQD9 cells, as measured by means of a colony survival assay. Our data reveal that apoptin treatment represents an effective way for enhancing radiotherapy of tumours responding poorly to radiotherapy.Experimental cancer immunology and therap

Cardiovascular risk factors in high-need psoriasis patients and its implications for biological therapies.

Item does not contain fulltextBACKGROUND: The associations between psoriasis and cardiovascular risk factors are reported to be stronger as psoriasis severity increases. This makes studying cardiovascular risk factors in high-need psoriasis patients, eligible for biological therapy, interesting. OBJECTIVE: To survey the prevalence of cardiovascular risk factors in high-need psoriasis patients and to compare these data to patients with other dermatological diseases. Furthermore, the implications of these findings for treatment with biologics were outlined. METHODS: The prevalence of cardiovascular risk factors was investigated in a high-need psoriatic patient cohort and compared to patients with other skin diseases who filled out a questionnaire about the presence of cardiovascular risk factors. RESULTS: A significantly higher prevalence of obesity, smoking, and hypertension was found for the high-need psoriatic patients' cohort compared with non-psoriatic controls. Striking differences were found with respect to body mass index and obesity, as 35.5% of all high-need psoriatic patients were obese. CONCLUSIONS: High-need psoriatic patients show a high prevalence of cardiovascular risk factors, and may consequently be predisposed to cardiovascular diseases. As this is relevant for therapy management in daily clinical practice, especially biologics, cardiovascular risk should be evaluated for each high-need psoriasis patient before and during systemic treatment

Treatment Preferences in Patients With Early Glottic Cancer

Objective: For early glottic carcinoma, the 2 main treatment modalities are radiotherapy (RT) and transoral CO2 laser microsurgery (TLM). The aim of this study was to investigate treatment preferences and considerations in patients with early glottic carcinoma (T1-T2) who were given a choice between TLM and RT.Subjects and Methods: Patients with early glottic cancer (suspected or confirmed extended T1 or limited T2) were counseled by an ENT-surgeon. A subset of 32 patients was also counseled by a radiotherapist. Treatment choice and considerations were recorded and analyzed.Results: Of 175 patients, 168 patients (96%) chose TLM, and 7 patients (4%) chose RT. The most common reason for choosing TLM was shorter treatment and more treatment options in case of recurrence. Subanalysis showed that additional counseling by the radiotherapist did not seem to affect our patients' preferences for TLM in this group.Conclusions: The majority of patients in our study prefer TLM to RT when given a choice. Reasons given indicate that optimizing future treatment options and practical considerations seemed more important to our patients than primary functional outcome. Further research is needed to study patient-related and physician-related factors to gain more insight into this complicated process of shared decision making.Otorhinolaryngolog

Occurence and trend analysis of organochlorine in animal feed

In this report historical data are used to give insight into the trends in levels of organochlorine compounds in compound feeds and feeding materials for animals in the Netherlands. The main focus is on pesticides, but non-dioxin-like PCBs have been studied as well. The latter will be included in the trend analysis reports about dioxins and dioxin-like PCBs in the future. This analysis was performed on request of the NVWA (Netherlands Food and Consumer Product Safety Authority). The results of these analyses will enable the NVWA to develop a risk-directed sampling strategy for the National Feed Monitoring program. More than 5000 feed samples were analysed for organochlorine compounds in the period 2001-2011. The materials in these samples originate from all over the world, but were sampled in the Netherlands. Samples were taken by the NVWA for the Netherlands National Feed Monitoring program and by the feed industry
