Identifying classes of the pain, fatigue, and depression symptom cluster in long-term prostate cancer survivors-results from the multi-regional Prostate Cancer Survivorship Study in Switzerland (PROCAS).

PURPOSE: Aside from urological and sexual problems, long-term (≥5 years after initial diagnosis) prostate cancer (PC) survivors might suffer from pain, fatigue, and depression. These concurrent symptoms can form a cluster. In this study, we aimed to investigate classes of this symptom cluster in long-term PC survivors, to classify PC survivors accordingly, and to explore associations between classes of this cluster and health-related quality of life (HRQoL). METHODS: Six hundred fifty-three stage T1-T3N0M0 survivors were identified from the Prostate Cancer Survivorship in Switzerland (PROCAS) study. Fatigue was assessed with the EORTC QLQ-FA12, depressive symptoms with the MHI-5, and pain with the EORTC QLQ-C30 questionnaire. Latent class analysis was used to derive cluster classes. Factors associated with the derived classes were determined using multinomial logistic regression analysis. RESULTS: Three classes were identified: class 1 (61.4%) - "low pain, low physical and emotional fatigue, moderate depressive symptoms"; class 2 (15.1%) - "low physical fatigue and pain, moderate emotional fatigue, high depressive symptoms"; class 3 (23.5%) - high scores for all symptoms. Survivors in classes 2 and 3 were more likely to be physically inactive, report a history of depression or some other specific comorbidity, be treated with radiation therapy, and have worse HRQoL outcomes compared to class 1. CONCLUSION: Three distinct classes of the pain, fatigue, and depression cluster were identified, which are associated with treatment, comorbidities, lifestyle factors, and HRQoL outcomes. Improving classification of PC survivors according to severity of multiple symptoms could assist in developing interventions tailored to survivors' needs.

The relative risk of second primary cancers in Switzerland: a population-based retrospective cohort study.

BACKGROUND: More people than ever before are currently living with a diagnosis of cancer and the number of people concerned is likely to continue to rise. Cancer survivors are at risk of developing a second primary cancer (SPC). This study aims to investigate the risk of SPC in Switzerland. METHODS: The study cohort included all patients with a first primary cancer recorded in 9 Swiss population-based cancer registries 1981-2009 who had a minimum survival of 6 months, and a potential follow-up until the end of 2014. We calculated standardized incidence ratios (SIR) to estimate relative risks (RR) of SPC in cancer survivors compared with the cancer risk of the general population. SIR were stratified by type of first cancer, sex, age and period of first diagnosis, survival period and site of SPC. RESULTS: A total of 33,793 SPC were observed in 310,113 cancer patients. Both male (SIR 1.18, 95%CI 1.16-1.19) and female (SIR 1.20, 95%CI 1.18-1.22) cancer survivors had an elevated risk of developing a SPC. Risk estimates varied substantially according to type of first cancer and were highest in patients initially diagnosed with cancer of the oral cavity and pharynx, Hodgkin lymphoma, laryngeal, oesophageal, or lung cancer. Age-stratified analyses revealed a tendency towards higher RR in patients first diagnosed at younger ages. Stratified by survival period, risk estimates showed a rising trend with increasing time from the initial diagnosis. We observed strong associations between particular types of first and SPC, i.e. cancer types sharing common risk factors such as smoking or alcohol consumption (e.g. repeated cancer of the oral cavity and pharynx (SIRmales 20.12, 95%CI 17.91-22.33; SIRfemales 37.87, 95%CI 30.27-45.48). CONCLUSION: Swiss cancer survivors have an increased risk of developing a SPC compared to the general population, particularly patients first diagnosed before age 50 and those surviving more than 10 years. Cancer patients should remain under continued surveillance not only for recurrent cancers but also for new cancers. Some first and SPCs share lifestyle associated risk factors making it important to promote healthier lifestyles in both the general population and cancer survivors.

Management and Outcome of Young Women (≤40 Years) with Breast Cancer in Switzerland.

Background: An increase in breast cancer (BC) incidence in young women (YW) as well as disparities in BC outcomes have been reported in Switzerland. We sought to evaluate treatment and outcome differences among YW with BC (YWBC). Methods: YW diagnosed with stage I-III BC between 2000−2014 were identified through nine cancer registries. Concordance with international guidelines was assessed for 12 items covering clinical/surgical management, combined in a quality-of-care score. We compared score and survival outcome between the two linguistic-geographic regions of Switzerland (Swiss-Latin and Swiss-German) and evaluated the impact of quality-of-care on survival. Results: A total of 2477 women were included. The median age was 37.3 years (IQR 34.0−39.4 years), with 50.3% having stage II BC and 70.3% having estrogen receptor positive tumors. The mean quality-of-care score was higher in the Latin region compared to the German region (86.0% vs. 83.2%, p < 0.0005). Similarly, 5- and 10-year overall survival rates were higher in the Latin compared to the German region (92.3% vs. 90.2%, p = 0.0593, and 84.3% vs. 81.5%, p = 0.0025, respectively). There was no difference in survival according to the score. In the univariate analysis, women in the Latin region had a 28% lower mortality risk compared to women in the German region (hazard ratio 0.72; 95% CI 0.59−0.89). In the multivariable analysis, only stage, differentiation, tumor subtype and treatment period remained independently associated with survival. Conclusions: We identified geographic disparities in the treatment and outcome of YWBC in Switzerland. National guidelines for YWBC should be implemented to standardize treatment. Awareness should be raised among YW and clinicians that BC does not discriminate by age.

Gender and hearing aids: patterns of use and determinants of nonregular use.

OBJECTIVE: Research addressing gender and hearing has focused mainly on differences in the auditory systems of men and women, communication, and psychological issues. Differences between men and women in the use of hearing aids are less clear. To date, no study has examined the effects of gender on hearing aid use as a primary aim. However, use patterns and underlying reasons for not using hearing aids may differ between men and women, or there might be a gender difference in the impact of some determinants on hearing aid use. A consideration of such factors could increase hearing aid use. Therefore, the aim of the present investigation was to provide information about gender-related influences on hearing aid use by examining differences in usage patterns and determinants of nonregular use. DESIGN: This study used cross-sectional survey data from 4979 adult male and 3410 adult female hearing aid owners in Switzerland in 2005. The survey data, including self-reported hearing aid use, were matched to the hearing loss data and the hearing aid technical information. Descriptive analyses were performed for the use patterns, age at first fitting, and audiogram slope. The determinants of nonregular use were examined using logistic regression models that were stratified by gender. RESULTS: Compared with men, women reported a higher prevalence of daily and regular use and a longer daily duration of use of hearing aids. Men more commonly indicated a limited benefit as a reason for nonregular use. The multivariate analyses showed that nonregular use was significantly less likely in women. The audiogram slope strongly contributed to this difference. Stratified analyses showed that for both men and women, poor handling and low satisfaction were associated with a higher likelihood for nonregular hearing aid use. Associations were discrepant for asymmetric hearing loss, which was a risk factor in women but a protective factor in men. Higher risks of nonregular use were found in men with steeper audiogram slopes and longer durations of ownership of their current aids, in women fitted with their first aid in the previous 2 to 5 yr, and in women older than 65 yr. CONCLUSIONS: Overall, the present study provides evidence of gender-specific factors that influence hearing aid use patterns in men and women and of groups at higher risk for nonregular hearing aid use. Men with steeper audiogram slopes and the other subgroups of men and women with an increased risk for nonregular use should given particular attention when fitting their aids. As common risk factors for nonregular use, poor handling and low satisfaction should be addressed during the fitting process for all users. Further research is needed to clarify the differential influence of asymmetric hearing loss on hearing aid use in men and women. This information could improve hearing aid use and should be incorporated into daily clinical practice.

Health-related quality of life in long-term prostate cancer survivors after nerve-sparing and non-nerve-sparing radical prostatectomy-Results from the multiregional PROCAS study.

BACKGROUND: Nerve-sparing (NS) surgery was developed to improve postoperative sexual and potentially urological outcomes after radical prostatectomy (RP). However, it is largely unknown how NSRP affects health-related quality of life (HRQoL) including urinary and sexual outcomes in prostate cancer (PC) survivors 5-10 years after diagnosis in comparison with Non-NSRP. METHODS: The study population included 382 stage pT2-T3N0M0 PC survivors 5-10 years post diagnosis, who were identified from the multiregional Prostate Cancer Survivorship in Switzerland (PROCAS) study. Briefly, in 2017/2018, PC survivors were identified via six population-based cancer registries based in both German- and French-speaking Switzerland. HRQoL and PC-specific symptom burden was assessed using the EORTC QLQ-C30 and EORTC QLQ-PR25 questionnaires. Differences in HRQoL outcomes between survivors treated with NSRP (uni- & bilateral) and Non-NSRP were analyzed with multivariable linear regression adjusted for age, years since diagnosis, cancer stage, comorbidities at diagnosis, and further therapies, if appropriate. Multiple imputation was performed to minimize the bias due to missing data. RESULTS: Five to ten years after diagnosis, PC survivors treated with NSRP and Non-NSRP reported similar symptom burden and comparable HRQoL function scores. The only significant differences were reported for sexual activity, whereas PC survivors who underwent NSRP reported statistically significant (P = .031) higher sexual activity than those on Non-NSRP. NSRP and Non-NSRP reported similar scores for urinary symptoms and all other HRQoL outcomes. CONCLUSIONS: Our results support nerve-sparing techniques as an option to improve postoperative sexual, but not urinary outcomes after RP in long-term PC survivors.

Survey on hearing aid use and satisfaction in Switzerland and their determinants.

The purpose of this study was to investigate the efficiency of the Swiss hearing aid dispensing system, and to determine factors contributing to successful hearing aid provision. A national cross sectional survey was performed using a postal questionnaire with 8707 adult hearing aid owners (response rate 62%). To correct results for a potential non-response bias, 193 randomly selected non-respondents were contacted by telephone. Data on hearing loss and type of hearing aid were provided by the hearing aid dispensing practice. Logistic regression analyses were performed to identify determinants of non-regular use and dissatisfaction. Eighty-five percent used their device(s) regularly, 12% only occasionally and 3% never. Eighty percent were satisfied with their aids. Non-regular use of hearing aids was significantly associated with age, gender, regional language, total duration of use, type of amplification, hearing aid category, hearing loss, and dissatisfaction with and difficulties in managing the aid. Dissatisfaction was associated with regional language, total duration of use, difficulties in managing the aid, and non-regular use. It was concluded that rates of regular hearing aid use and satisfaction are high in Switzerland.

Changes in oral health over a 10-yr period in Switzerland.

The Swiss Health Surveys are conducted every 5 yr, and alternate surveys contain information on oral health. Worldwide the population is ageing and oral health is improving. The aim of this study was to identify if these trends are continuing in a relatively affluent society with low levels of edentulousness. Participants in the 1992 and 2002 surveys completed a written questionnaire including items on oral health (response rates 75% and 86% respectively). Data were weighted and bivariate analyses were performed to calculate the average number of missing teeth and the prevalence of different prosthetic dental restorations for each cohort. Over the 10-yr period the proportion of subjects retaining all natural teeth increased, and the mean number of teeth increased, on average, by 1.3. Among those who required prosthetic dental restorations, fixed restorations increased and complete denture use was reduced. Strikingly, 4.4% of this sample reported having oral implants in 2002. Greater numbers of missing teeth and a higher prevalence of use of removable prostheses were still seen in women, in those who had only completed compulsory education, in subjects from families with low income, in those who smoke, and in those who were overweight, in 2002.

Predictors of early postpartum mental distress in mothers with midwifery home care--results from a nested case-control study.

PRINCIPLES: The prevalence of early postpartum mental health conditions is high. Midwives and other health professionals visiting women at home may identify mothers at risk. This seems crucial given decreasing trends of length of hospital stay after childbirth. This study aimed to identify predictors of maternal mental distress in a midwifery home care setting. METHODS: Using the statistical database of independent midwives' services in Switzerland in 2007, we conducted a matched nested case-control study. Out of a source population of 34,295 mothers with midwifery home care in the first ten days after childbirth, 935 mothers with maternal distress and 3,645 controls, matched by midwife, were included. We analysed whether socio-demographic, maternal and neonatal factors predict maternal mental distress by multivariable conditional logistic regression analysis. RESULTS: Infant crying problems and not living with a partner were the strongest predictors for maternal distress, whereas higher parity was the most protective factor. Significantly elevated risks were also found for older age, lower educational levels, breast/breastfeeding problems, infant weight gain concerns, neonatal pathologies and use of midwifery care during pregnancy. A lower likelihood for maternal distress was seen for non-Swiss nationality, full-time employment before birth, intention to return to work after birth and midwife-led birth. CONCLUSION: The study informs on predictors of maternal mental distress identified in a home care setting in the early postpartum period. Midwives and other health care professionals should pay particular attention to mothers of excessively crying infants, single mothers and primipara, and assess the need for support of these mothers.

Marital status, living arrangement and mortality: does the association vary by gender?

BACKGROUND: Men appear to benefit more from being married than women with respect to mortality in middle age. However, there is some uncertainty about gender differences in mortality risks in older individuals, widowed, divorced and single individuals and about the impact of living arrangements. METHODS: Longitudinal data with 1990 census records being linked to mortality data up to 2005 were used (Swiss National Cohort). The sample comprised all residents over age 44 years in Switzerland (n=2,440,242). All-cause mortality HRs for marital status and living arrangements were estimated by Cox regression for men and women and different age groups with adjustment for education and socio-professional category. RESULTS: The benefit of being married was stronger for men than for women; however, mortality patterns were similar, with higher mortality in divorced and single individuals compared with widowed individuals (<80 years). After adjustment for living arrangements, the gender difference by marital status disappeared. Stratification by living arrangement revealed that mortality risks were highest for 45-64-year-old divorced (HR 1.72 (95% CI 1.67 to 1.76)) and single men (HR 1.67 (95% CI 1.63 to 1.71)) who lived alone. In women of the same age, the highest mortality risk was observed for those who were single and living with a partner (HR 1.70 (95% CI 1.58 to 1.82)). In older age groups, the impact of marital status decreased. CONCLUSIONS: Evaluation of living arrangements is crucial for identifying and explaining gender differences in mortality risks by marital status. The impact of living alone and living with a partner seems to be different in men and women.

Predictors of crying problems in the early postpartum period.

OBJECTIVE: To investigate maternal and infant factors associated with midwife-reported crying problems in the early postpartum period. DESIGN: Case control study. SETTING: Postnatal home care in Switzerland. PARTICIPANTS: Seven thousand seven hundred and sixty-five mother/child dyads who received postnatal homecare by midwives (n=1,636 cases of midwife-reported crying problems, n=6,129 controls). METHODS: We investigated factors associated with infant crying problems during the postpartum period as documented in the Statistical Database of Independent Midwives' Services in Switzerland (2007). Using case control methodology, we matched all identified cases of crying problems with controls who had been cared for by the same midwife. A conditional logistic regression model was used to analyze the associations of reported crying problems with maternal and infant factors. RESULTS: Maternal health and mood problems in the immediate postpartum period were significantly associated with reported crying problems. Maternal health and mood problems included physical complications after birth, psychological decompensation, and depression. Further risk factors for infant crying problems were planned resumption of paid work directly after paid maternity leave (at 15-16 weeks postpartum) and immigrant status. A protective effect was observed for higher parity. CONCLUSIONS: Crying problems in the early postpartum period are associated with mothers' physical, psychological, and social conditions. Care practices that promote new mothers' physical and psychological recovery after birth could be a promising strategy to prevent early crying problems. Specific support is important for mothers with early signs of depression or decompensation, intention to return early to paid work, immigrant background, and for first-time mothers.

Length of maternity leave and health of mother and child--a review.

OBJECTIVES: Assessment of the literature on the length of maternity leaves and health of mothers and children; evaluation of the Swiss situation in view of the maternity leave policy implemented in 2005. METHODS: Review of thirteen original studies identified by PubMed using topic-related terms. RESULTS: A positive association was shown between the length of maternity leave and mother's mental health and duration of breastfeeding. Extended maternity leaves were also associated with lower perinatal, neonatal and post-neonatal mortality rates as well as lower child mortality; however, results are obtained in ecological studies. There is less evidence regarding other health outcomes. The new policy in Switzerland extends maternity leave for a considerable number of women to 14 weeks. With this prolongation, fewer depressive symptoms and longer breastfeeding duration can be expected, while benefits regarding other health outcomes would warrant longer leaves. CONCLUSIONS: Longer maternity leaves are likely to produce health benefits. The new policy in Switzerland will probably improve the situation of those women, who previously were granted only minimal leave and/or mothers with additional social risk factors.
