Work changes and employee age, maladaptive coping expectations, and well-being: a Swedish cohort study
Work changes and employee age, maladaptive coping expectations, and well-being: a Swedish cohort study
PURPOSE: Older workers are expected to suffer more from work changes than younger ones, but empirical evidence is lacking. Negative responses to work changes may result rather from maladaptive coping expectations. This study examined possible age differences in job and life satisfaction, and sleep disturbances, after work changes (voluntary and involuntary job changes, reorganizations) and the moderating role of maladaptive coping expectations. METHODS: Four biennial waves from the Swedish Longitudinal Occupational Survey of Health (SLOSH) including respondents who participated in all four waves (n = 3084). We used multilevel path analyses to estimate direct and moderated relationships between work changes and outcomes. RESULTS: Involuntary job changes were associated with lower job and life satisfaction and more sleep disturbances. Reorganizations were only associated with lower job satisfaction. Older employees were more satisfied with their jobs and lives than younger employees and experienced more sleep disturbances. After involuntary job changes, older employees had similar (lower) levels of well-being as younger ones, but they reported more sleep disturbances when having experienced reorganizations. Maladaptive coping expectations were related to lower job and life satisfaction and more sleep disturbances. Employees with maladaptive coping expectations reported more sleep disturbances after involuntary job changes and reorganizations. CONCLUSION: Our results suggest that there are few age differences in well-being after work changes. Employee well-being seems to mostly depend on maladaptive coping expectations. Organizations aiming to prepare employees for job changes and reorganizations could focus their efforts on employees with maladaptive expectations rather than on older ones
Perseverative cognition as an explanatory mechanism in the relation between job demands and sleep quality
Combination, Modulation and Interplay of Modern Radiotherapy with the Tumor Microenvironment and Targeted Therapies in Pancreatic Cancer: Which Candidates to Boost Radiotherapy?
Pancreatic ductal adenocarcinoma cancer (PDAC) is a highly diverse disease with low tumor immunogenicity. PDAC is also one of the deadliest solid tumor and will remain a common cause of cancer death in the future. Treatment options are limited, and tumors frequently develop resistance to current treatment modalities. Since PDAC patients do not respond well to immune checkpoint inhibitors (ICIs), novel methods for overcoming resistance are being explored. Compared to other solid tumors, the PDAC's tumor microenvironment (TME) is unique and complex and prevents systemic agents from effectively penetrating and killing tumor cells. Radiotherapy (RT) has the potential to modulate the TME (e.g., by exposing tumor-specific antigens, recruiting, and infiltrating immune cells) and, therefore, enhance the effectiveness of targeted systemic therapies. Interestingly, combining ICI with RT and/or chemotherapy has yielded promising preclinical results which were not successful when translated into clinical trials. In this context, current standards of care need to be challenged and transformed with modern treatment techniques and novel therapeutic combinations. One way to reconcile these findings is to abandon the concept that the TME is a well-compartmented population with spatial, temporal, physical, and chemical elements acting independently. This review will focus on the most interesting advancements of RT and describe the main components of the TME and their known modulation after RT in PDAC. Furthermore, we will provide a summary of current clinical data for combinations of RT/targeted therapy (tRT) and give an overview of the most promising future directions
Molecular epidemiology of antiretroviral resistance in therapy-experienced HIV-1 patients in Cuba (2009)
Different evolution of genotypic resistance profiles to emtricitabine versus lamivudine in tenofovir-containing regimens.
BACKGROUND: To investigate genotypic resistance profiles to emtricitabine +
tenofovir (FTC + TDF) in-vivo and in-vitro, and compare them with lamivudine +
tenofovir (3TC + TDF).
METHODS: Three hundred fifty-two HIV-1 B-subtype pol sequences from 42 FTC +
TDF-treated patients, 40 3TC + TDF-treated patients, and 270 patients treated
with 3TC plus another nucleoside reverse transcriptase inhibitor (but not TDF).
All patients never received FTC, 3TC, and TDF in their previous therapeutic
regimen. 3TC/FTC ± TDF resistance was investigated using in vitro selection
experiments and docking simulations.
RESULTS: The M184V mutation is less prevalent in FTC + TDF-treated patients than
in 3TC + TDF-treated, and 3TC-treated/TDF-naive patients (14.3% versus 40.0%, P =
0.01 and 55.6%, P < 0.001). Multivariable analysis shows that factors correlated
with a lower probability of M184V emergence at failure were the use of FTC
compared with 3TC [odds ratio (OR): 0.32 (95% confidence interval (CI): 0.10 to
0.99), P = 0.04], the use of boosted protease inhibitor, and the use of TDF [OR:
0.20 (95% CI: 0.11 to 0.37), P < 0.001, and OR: 0.47 (95%CI: 0.22 to 1.01), P =
0.05, respectively]. In vitro selection experiments and docking analysis show
that other reverse transcriptase (RT) mutations, even localized in RT connection
domain, can be selected by 3TC + TDF or FTC + TDF in M184V absence and can affect
RT affinity for 3TC/FTC and/or TDF.
CONCLUSIONS: Our study shows lower rates of M184V development in FTC + TDF
regimens versus 3TC + TDF and suggests a potential role of boosted protease
inhibitors and TDF in delaying the M184V emergence. Novel RT mutational patterns,
more complex than currently known, can contribute to 3TC, FTC, and TDF
resistance
Association of Prognostic Value of Primary Tumor Location in Stage III Colon Cancer With RAS and BRAF Mutational Status.
The management of pancreatic cancer. Current expert opinion and recommendations derived from the 8th World Congress on Gastrointestinal Cancer, Barcelona, 2006
This article summarizes the expert discussion on the management of pancreatic cancer, which took place during the 8th World Congress on Gastrointestinal Cancer in June 2006 in Barcelona. A multidisciplinary approach to a patient with pancreatic cancer is essential, in order to guarantee an optimal staging, surgery, selection of the appropriate (neo-)adjuvant strategy and chemotherapeutic choice management. Moreover, optimal symptomatic management requires a dedicated team of health care professionals. Quality control of surgery and pathology is especially important in this disease with a high locoregional failure rate. There is now solid evidence in favour of chemotherapy in both the adjuvant and palliative setting, and gemcitabine combined with erlotinib, capecitabine or platinum compounds seems to be slightly more active than gemcitabine alone in advanced pancreatic cancer. There is a place for chemoradiotherapy in selected patients with locally advanced disease, while the role in the adjuvant setting remains controversial. Those involved in the care for patients with pancreatic cancer should be encouraged to participate in well-designed clinical trials, in order to increase the evidence-based knowledge and to make further progres
