Atypical working hours are associated with tobacco, cannabis and alcohol use: longitudinal analyses from the CONSTANCES cohort.

BACKGROUND: This study examined prospective associations between atypical working hours with subsequent tobacco, cannabis and alcohol use as well as sugar and fat consumption. METHODS: In the French population-based CONSTANCES cohort, 47,288 men and 53,324 women currently employed included between 2012 and 2017 were annually followed for tobacco and cannabis use. Among them, 35,647 men and 39,767 women included between 2012 and 2016 were also followed for alcohol and sugar and fat consumption. Three indicators of atypical working hours were self-reported at baseline: working at night, weekend work and non-fixed working hours. Generalized linear models computed odds of substance use and sugar and fat consumption at follow-up according to atypical working hours at baseline while adjusting for sociodemographic factors, depression and baseline substance use when appropriate. RESULTS: Working at night was associated with decreased smoking cessation and increased relapse in women [odds ratios (ORs) of 0.81 and 1.25], increased cannabis use in men [ORs from 1.46 to 1.54] and increased alcohol use [ORs from 1.12 to 1.14] in both men and women. Weekend work was associated with decreased smoking cessation in women [ORs from 0.89 to 0.90] and increased alcohol use in both men and women [ORs from 1.09 to 1.14]. Non-fixed hours were associated with decreased smoking cessation in women and increased relapse in men [ORs of 0.89 and 1.13] and increased alcohol use in both men and women [ORs from 1.12 to 1.19]. Overall, atypical working hours were associated with decreased sugar and fat consumption. CONCLUSIONS: The potential role of atypical working hours on substance use should be considered by public health policy makers and clinicians in information and prevention strategies.

Public Knowledge of, Perceptions About and Attitudes Towards Dementia: A Cross-Sectional Survey Among Lebanese Primary Health Care Attenders.

Dementia is a leading cause of dependency and disability among older adults. Minimal knowledge, poor attitudes and negative perceptions are barriers of dementia early screening, diagnosis and treatment. This is the first study that assesses knowledge, attitudes and perceptions of dementia among a Middle Eastern population. Two hundred and fifty-four Lebanese adults not having dementia attending primary healthcare centers in the capital of Lebanon were interviewed using an Arabic version of the 2010 Northern Ireland Life and Times survey. The highest proportion of the participants (61%) had low knowledge score. Low knowledge was associated with older age and lower education. The majority had a negative perception towards people living with dementia and these perceptions were significantly different by gender, education and exposure. Participants perceived people with dementia as helpless and dependent. Public interventions should address stigma and increase knowledge while understanding the socio-cultural beliefs associated with dementia. The study calls for policy developments and conducting a qualitative study.

An augmented patient-specific approach to administration of contrast agent for CT renal angiography.

PURPOSE: This hybrid retrospective and prospective study performed on 200 consecutive patients undergoing renal CTA, investigates the opacification of renal vasculature, radiation dose, and reader confidence. MATERIALS AND METHODS: 100 patients were assigned retrospectively to protocol A and the other 100 were allocated prospectively to protocol B. Both protocols implemented a contrast material and saline flow rate of 4.5 mL/sec. Protocol A utilized a 100 mL of low-osmolar nonionic IV contrast material (Ioversol 350 mg I/mL) while protocol B employed a patient-tailored contrast media formula using iso-osmolar non-ionic (Iodixanol 320 mg I/mL). RESULTS: Arterial opacification in the abdominal aorta and in the bilateral main proximal renal arteries demonstrated no statistical significance (p>0.05). Only the main distal renal artery of the left kidney in protocol B was statistically significant (p<0.046). In the venous circulation, the IVC demonstrated a significant reduction in opacification in protocol B (59.39 HU ± 19.39) compared to A (87.74 HU ± 34.06) (p<0.001). Mean CNR for protocol A (22.68 HU ± 13.72) was significantly higher than that of protocol B (14.75 HU ± 5.76 p<0.0001). Effective dose was significantly reduced in protocol B (2.46 ± 0.74 mSv) compared to A (3.07 ± 0.68 mSv) (p<0.001). Mean contrast media volume was reduced in protocol B (44.56 ± 14.32 mL) with lower iodine concentration. ROC analysis demonstrated significantly higher area under the ROC curve for protocol B (p<0.0001), with inter-reader agreement increasing from moderate to excellent in renal arterial visualization. CONCLUSION: Employing a patient-tailored contrast media injection protocol shows a significant refinement in the visualization of renal vasculature and reader confidence during renal CTA.

Augmented Quadruple-Phase Contrast Media Administration and Triphasic Scan Protocol Increases Image Quality at Reduced Radiation Dose During Computed Tomography Urography.

PURPOSE: The aim of this article was to investigate the opacification of the renal vasculature and the urogenital system during computed tomography urography by using a quadruple-phase contrast media in a triphasic scan protocol. MATERIALS AND METHODS: A total of 200 patients with possible urinary tract abnormalities were equally divided between 2 protocols. Protocol A used the conventional single bolus and quadruple-phase scan protocol (pre, arterial, venous, and delayed), retrospectively. Protocol B included a quadruple-phase contrast media injection with a triphasic scan protocol (pre, arterial and combined venous, and delayed), prospectively. Each protocol used 100 mL contrast and saline at a flow rate of 4.5 mL. Attenuation profiles and contrast-to-noise ratio of the renal arteries, veins, and urogenital tract were measured. Effective radiation dose calculation, data analysis by independent sample t test, receiver operating characteristic, and visual grading characteristic analyses were performed. RESULTS: In arterial circulation, only the inferior interlobular arteries in both protocols showed a statistical significance (P < 0.05). Venously, the inferior vena cava, proximal and distal renal veins demonstrated a significant opacification reduction in protocol B than in protocol A (P < 0.001). Protocol B showed a significantly higher mean contrast-to-noise ratio than protocol A (protocol B: 22.68 ± 13.72; protocol A: 14.75 ± 5.76; P < 0.001). Radiation dose was significantly reduced in protocol B (7.38 ± 2.22 mSv) than in protocol A (12.28 ± 2.72 mSv) (P < 0.001). Visual grading characteristic (P < 0.027) and receiver operating characteristic (P < 0.0001) analyses demonstrated a significant preference for protocol B. CONCLUSIONS: In computed tomography urography, augmented quadruple-phase contrast media and triphasic scan protocol usage increases the image quality at a reduced radiation dose.

Qualitative and quantitative radiological analysis of non-contrast CT is a strong indicator in patients with acute pyelonephritis.

OBJECTIVE: To evaluate the performance of non-contrast computed tomography (CT) by reporting the difference in attenuation between normal and inflamed renal parenchyma in patients clinically diagnosed with acute pyelonephritis (APN). MATERIAL AND METHODS: This is a retrospective study concerned with non-contrast CT evaluation of 74 patients, admitted with a clinical diagnosis of APN and failed to respond to 48h antibiotics treatment. Mean attenuation values in Hounsfield units (HU) were measured in the upper, middle and lower segments of the inflamed and the normal kidney of the same patient. Independent t-test was performed for statistical analysis. Image evaluation included receiver operating characteristic (ROC), visual grading characteristic (VGC) and kappa analyses. RESULTS: The mean attenuation in the upper, middle and lower segments of the inflamed renal cortex was 32%, 25%, and 29% lower than the mean attenuation of the corresponding cortical segments of the contralateral normal kidney, respectively (p<0.01). The mean attenuation in the upper, middle, and lower segments of the inflamed renal medulla was 48%, 21%, and 30%, lower than the mean attenuation of the corresponding medullary segments of the contralateral normal kidney (p<0.02). The mean attenuation between the inflamed and non-inflamed renal cortex and medulla was 29% and 30% lower respectively (p<0.001). The AUCROC (p<0.001) analysis demonstrated significantly higher scores for pathology detection, irrespective of image quality, compared to clinical and laboratory results with an increased inter-reader agreement from poor to substantial. CONCLUSION: Non-contrast CT showed a significant decrease in the parenchymal density of the kidney affected with APN in comparison to the contralateral normal kidney of the same patient. This can be incorporated in the diagnostic criteria of APN in NCCT in the emergency setting.

Physical exertion at work and addictive behaviors: tobacco, cannabis, alcohol, sugar and fat consumption: longitudinal analyses in the CONSTANCES cohort.

We examined the prospective association of physical exertion at work with subsequent tobacco, cannabis, alcohol use, and sugar and fat consumption. Volunteers of the French population-based CONSTANCES cohort currently employed were included from 2012 to 2017 for tobacco and cannabis outcomes (n = 100,612), and from 2012 to 2016 for alcohol and sugar and fat outcomes (n = 75,414). High level of physical exertion at work was defined as a score ≥ 12 at the Rating Perceived Exertion Borg scale. Substance use was self-reported and diet rich in sugar and fat was obtained from principal component analysis and analyzed as quartiles. Generalized linear models computed odds of substance use and sugar and fat consumption at follow-up according to baseline physical exertion at work, while adjusting for sociodemographic factors, depressive symptoms and baseline level of consumption. High physical exertion was associated with tobacco use with dose-dependent relationships. It was also associated with increased odds of cannabis use at least once per month compared to no use in the past and with increased odds of diet rich in sugar and fat. Hence, the role of physical exertion at work on tobacco and cannabis use and diet rich in sugar and fat should be tackled for information and prevention strategies.

Racial Disparities in Prostate Cancer: Evaluation of Diet, Lifestyle, Family History, and Screening Patterns.

BACKGROUND: Racial disparities in prostate cancer incidence and mortality rates are considerable. We previously found in the Health Professionals Follow-up Study (HPFS) that African-American men had an 80% higher prostate cancer risk than White men. With 21 additional years of follow-up and four-fold increase in cases, we undertook a contemporary analysis of racial differences in prostate cancer incidence and mortality in HPFS. METHODS: For 47,679 men, we estimated HRs and 95% confidence intervals (CI) for the association between race and risk of prostate cancer through 2016 using Cox proportional hazards regression. Multivariable models (mHR) were adjusted for lifestyle, diet, family history, and PSA screening collected on biennial questionnaires. RESULTS: 6,909 prostate cancer cases were diagnosed in White, 89 in African-American, and 90 in Asian-American men. African-Americans had higher prostate cancer incidence (mHR = 1.31; 95% CI, 1.06-1.62) and mortality (mHR = 1.67; 95% CI, 1.00-2.78), and lower PSA screening prevalence than White men. The excess risk was greater in the pre-PSA screening era (HR = 1.68; 95% CI, 1.14-2.48) than the PSA screening era (HR = 1.20; 95% CI, 0.93-1.56). Asian-Americans had lower prostate cancer risk (mHR = 0.74; 95% CI, 0.60-0.92), but similar risk of fatal disease compared with white men. CONCLUSIONS: Racial differences in prostate cancer incidence and mortality in HPFS are not fully explained by differences in lifestyle, diet, family history, or PSA screening. IMPACT: Additional research is necessary to address the disproportionately higher rates of prostate cancer in African-American men.

Depressive symptoms and non-adherence to treatable cardiovascular risk factors' medications in the CONSTANCES cohort.

AIMS: Depression is associated with increased risk of cardiovascular disease (CVD) and the role of poor medical adherence is mostly unknown. We studied the association between depressive symptoms and non-adherence to medications targeting treatable cardiovascular risk factors in the CONSTANCES population-based French cohort. METHODS AND RESULTS: We used CONSTANCES data linked to the French national healthcare database to study the prospective association between depressive symptoms (assessed at inclusion with the Center for Epidemiological Studies Depression scale) and non-adherence to medications (less than 80% of trimesters with at least one drug dispensed) treating type 2 diabetes, hypertension, and dyslipidaemia over 36 months of follow-up. Binary logistic regression models were adjusted for socio-demographics, body mass index, and personal history of CVD at inclusion. Among 4998 individuals with hypertension, 793 with diabetes, and 3692 with dyslipidaemia at baseline, respectively 13.1% vs. 11.5%, 10.5% vs. 5.8%, and 29.0% vs. 27.1% of those depressed vs. those non-depressed were non-adherent over the first 18 months of follow-up (15.9% vs. 13.6%, 11.1% vs. 7.4%, and 34.8% vs. 36.6% between 19 and 36 months). Adjusting for all covariates, depressive symptoms were neither associated with non-adherence to medications for hypertension, diabetes, and dyslipidaemia over the first 18 months of follow-up, nor afterwards. Depressive symptoms were only associated with non-adherence to anti-diabetic medications between the first 3-6 months of follow-up. CONCLUSION: Non-adherence to medications targeting treatable cardiovascular risk factors is unlikely to explain much of the association between depressive symptoms and CVD at a population level. Clinicians are urged to search for and treat depression in individuals with diabetes to foster medications adherence.

Lung density in the trajectory path is a strong indicator of patients sustaining a pneumothorax during CT-guided lung biopsy.

INTRODUCTION: The purpose is to evaluate the prognostic significance of lung parenchymal density during percutaneous coaxial cutting needle lung biopsy (PNLB). MATERIALS AND METHODS: Retrospective analysis of 179 consecutive patients (106 males, 73 females; mean age 59.16 ± 16.34 years) undergoing PNLB was included. Mean lobar parenchymal lung density, mean densities anterior to the lesion and posterior to the chest wall in the needle trajectory path were measured in HU. Lesion location and needle trajectory were also measured. Fisher's exact test and Chi-square test were conducted to analyze the categorical variables. ANOVA test was done to examine continuous and normally distributed variables. Statistical significance was considered when p < 0.05. RESULTS: Mean lobar parenchymal lung density (p < 0.05) and mean parenchymal lung density relative to the needle trajectory path were below -800 HU in patients who sustained a pneumothorax. Increase in the number of pleural passes was significantly associated with the risk of patients having pneumothorax (p < 0.05). The mean distance from the skin to the lesion and needle trajectory angle were not statistically different among patients with and without pneumothorax (p > 0.05). CONCLUSION: Lobar parenchymal density and lung parenchymal density anterior to the lesion and posterior to the chest wall in the needle trajectory path could be used as predicting parameters in patients undergoing PNLB who sustained a pneumothorax. These findings can help interventional radiologist further assess risk of pneumothorax when preforming such procedure.

Hostility, depression and incident cardiac events in the GAZEL cohort.

BACKGROUND: Psychological factors such as hostility and depression have been associated with cardiovascular disease. However, their role in predicting incident cardiac events independently one of another is not clear. METHODS: Among 10,304 GAZEL middle-aged workers free of cardiovascular diseases in 1993, 581 incident cardiac events were validated from 1994-2014. Hostile traits (cognitive hostility, behavioral hostility, irritability and negativism) were assessed with the Buss and Durkee Hostility Inventory at baseline. Depressive symptoms were assessed at baseline and every three years with the Center for Epidemiological Studies Depression scale. We used Cox proportional hazards models to calculate hazard ratios (HR) of hostile traits for incident cardiac events adjusting for baseline self-reported socio-demographics and family history of coronary heart diseases (model 1), then additionally for time-dependent depressive symptoms (either as a binary or continuous variable) (model 2) and for yearly self-reported modifiable cardiovascular risk factors (physical activity, smoking, body mass index, diabetes, dyslipidemia and hypertension) (model 3). RESULTS: In Model 1, the only hostile trait associated with incident cardiac events was irritability (HR for one interquartile range: 1.16, 95% confidence interval: 1.02-1.32). This association was no longer statistically significant when further adjusting for depressive symptoms. Depressive symptoms, in turn, remained significant predictors of cardiac events with HRs ranging from 1.40-1.49 (binary). LIMITATIONS: Hostility traits were measured only once. CONCLUSIONS: Depressive symptoms might explain the association between irritability and cardiac events and should therefore be prioritized in interventions aiming to prevent cardiovascular disease. Further research is needed to identify the mechanisms underlying this association.

Depression, treatable cardiovascular risk factors and incident cardiac events in the Gazel cohort.

BACKGROUND: Depression is an important risk factor of cardiovascular disease (CVD), a leading cause of death worldwide. One of the reasons underlying this association may be that depression modifies the association between treatable cardiovascular risk factors and cardiac events (angina pectoris or myocardial infarction). We tested this hypothesis in a cohort study of middle-aged men and women in France followed for 20 years. METHODS: 10,541 Gazel working men and women free of cardiovascular disease at baseline (1993) were followed-up over 20 years for validated incident cardiac events. Depression was measured at baseline and every three years with the Center for Epidemiological Studies-Depression (CES-D). We used time-dependent Cox regression models to calculate hazard ratios (HR) of cardiac events associated with depression, main treatable cardiovascular risk factors (hypertension, diabetes, and dyslipidemia), and their interactions, adjusting for demographic, lifestyle and clinical characteristics. RESULTS: Over 20 years of follow-up, 592 incident cases of cardiac events were identified. Depression was significantly associated with incident cardiac events (HR 1.55, P = 0.002), as was hypertension (HR 1.49, P = 0.02), diabetes (HR 2.54, P = 0.001), and dyslipidemia (HR 1.55, P = 0.003). No statistically significant interactions were observed between depression and hypertension, diabetes or dyslipidemia in relation to incident cardiac events (all P ≥ 0.16). CONCLUSIONS: The association between depression and cardiac events is unlikely to be explained by a heightened impact of hypertension, diabetes or dyslipidemia.

Cancer-Related Pain: Prevalence, Severity and Management in a Tertiary Care Center in the Middle East

Background: Despite pain awareness and the development of treatment guidelines, cancer-related pain assessment and management remain suboptimal. Our objectives were to estimate the prevalence and severity of pain and its interference with daily activities, and evaluate adequacy of treatment in cancer patients in Lebanon. Methods: A total of 400 cancer patients aged 18 and above were interviewed at the American University of Beirut Medical Center surgical and medical oncology floors, outpatient clinics and chemotherapy units from March 2016-February 2017. The subjects covered were socio-demographics, clinical data, and presence of pain in the past month with use of the Brief Pain Inventory questionnaire. Descriptive statistics were conducted using t-test, chi-square and Fischer's exact tests. Pearson's correlation coefficients were used to examine relationships between pain severity and pain interference. Logistic regression was employed to determine risk factors for pain. Results: The majority of participants were Lebanese (76.0%), females (62.7%), married (80.2%), of Muslim faith (64.2%), of urban residence (85.8%), and with insurance plans (81.3%). Most had breast cancer (38.8%), were stage 4 (52.7%) and underwent a combination of surgery and systemic therapy (55.1%). The prevalence of pain in the past month was 29.8%. Among patients with pain, the highest proportion had moderate pain (37.8%) and around 46% received inadequate treatment. Conclusion: More awareness about cancer-related pain is needed to improve pain management and encourage referral to palliative care and pain specialists early-on in diagnosis of disease.

Second primary malignancy after radical prostatectomy in a cohort from the Middle East.

BACKGROUND: Data from the Middle East regarding second primary malignancy (SPM) after radical prostatectomy are limited. Our objective was to estimate the overall risk of developing second primary malignancy (SPM) among Middle Eastern men with prostate cancer who underwent surgical extirpation of their prostate. MATERIALS AND METHODS: We conducted a retrospective study of 406 patients who underwent radical prostatectomy in a tertiary centre and who had no evidence of previous malignancy from 1998 to 2012. Standardized incidence ratios (SIRs) and 95% confidence interval (CI) were calculated to analyze the risk of SPM in our population compared with the general population. Cox-regression models were also conducted to correlate the clinicopathological factors with the development of SPM. RESULTS: After 14 years of follow-up, the incidence rate of SPM was 100.9 per 1,000 person-years. The most frequent SPMs were bladder cancer (n = 11, 27%) followed by hematological malignancies (n = 9, 22%) and lung cancer (n = 7, 17%). The overall risk for men with prostate cancer to develop SPM is lower than the men in the general population (standardized incidence ratios = 0.19; 95% CI: 0.14-0.25). A multivariate analysis failed to correlate any of the clinicopathological factors with the development of SPM. CONCLUSION: Patients with prostate cancer who underwent surgical expiration of their prostate are at lower risk of developing SPM compared with the general population.

An augmented patient-specific approach to administration of contrast agent for CT renal angiography

ABSTRACT Purpose This hybrid retrospective and prospective study performed on 200 consecutive patients undergoing renal CTA, investigates the opacification of renal vasculature, radiation dose, and reader confidence. Materials and Methods 100 patients were assigned retrospectively to protocol A and the other 100 were allocated prospectively to protocol B. Both protocols implemented a contrast material and saline flow rate of 4.5 mL/sec. Protocol A utilized a 100 mL of low-osmolar nonionic IV contrast material (Ioversol 350 mg I/mL) while protocol B employed a patient-tailored contrast media formula using iso-osmolar non-ionic (Iodixanol 320 mg I/mL). Results Arterial opacification in the abdominal aorta and in the bilateral main proximal renal arteries demonstrated no statistical significance (p>0.05). Only the main distal renal artery of the left kidney in protocol B was statistically significant (p<0.046). In the venous circulation, the IVC demonstrated a significant reduction in opacification in protocol B (59.39 HU ± 19.39) compared to A (87.74 HU ± 34.06) (p<0.001). Mean CNR for protocol A (22.68 HU ± 13.72) was significantly higher than that of protocol B (14.75 HU ± 5.76 p< 0.0001). Effective dose was significantly reduced in protocol B (2.46 ± 0.74 mSv) compared to A (3.07 ± 0.68 mSv) (p<0.001). Mean contrast media volume was reduced in protocol B (44.56 ± 14.32 mL) with lower iodine concentration. ROC analysis demonstrated significantly higher area under the ROC curve for protocol B (p< 0.0001), with inter-reader agreement increasing from moderate to excellent in renal arterial visualization. Conclusion Employing a patient-tailored contrast media injection protocol shows a significant refinement in the visualization of renal vasculature and reader confidence during renal CTA.
