Symptom burden and work-related impairment among patients with PTSD and complex PTSD

Background: The 11th revision of the International Classification of Diseases includes a newchapter of stress-related disorders and presents two distinct sibling conditions:Posttraumatic stress disorder (PTSD) and complex PTSD (CPTSD). Studies show that PTSDand CPTSD are associated with different levels of symptom burden, comorbidity andfunctional impairment, but have not yet addressed the qualitative and quantitative differences in work-related impairment between the two diagnoses.Objective: The aim of this study was to replicate differences in symptom severity, globaldistress, and the number of comorbid diagnoses between three groups that suffer from noPTSD, PTSD, or CPTSD. More importantly, we evaluated whether the three groups differ inindicators of functional impairment such as qualitative and quantitative working capacity.Finally, this study supplies information on prevalence rates of PTSD and CPTSD in a clinicalsample suffering from psychosomatic complaints.Methods: Participants were 662 patients of a Psychosomatic Rehabilitation Clinic (ageM= 50.99,SD8.99 years; 70.1% female). Self-report screening instruments were adminis-tered to participants at the beginning of their inpatient psychotherapy. Multivariate analysisof variance and Chi Square tests were utilized to assess group differences in symptomseverity, comorbidity and work-related impairment.Results: A prevalence of 13.3% CPTSD and 9.5% PTSD was found among the current sample.CPTSD was associated with heightened symptom burden and more comorbid diagnoses.More importantly, CPTSD was associated with a significantly lowered qualitative and quan-titative working capacity compared to PTSD and no-PTSD.Conclusions: The high prevalence, greater psychopathological burden and work-relatedimpairments in CPTSD compared to PTSD highlight the need for developing and evaluatingnew interventions in rehabilitation that address the complexity of the new disorder

Smoking and γ-Glutamyltransferase: Opposite Interactions with Alcohol Consumption and Body Mass Index

BACKGROUND: Smoking has recently been suggested to synergistically interact with alcohol intake as a determinant of serum gamma-glutamyltransferase (γ-GT), an emergent powerful predictor of disease and mortality. This study investigated whether this also applies to higher smoking and alcohol exposure ranges and to body mass index (BMI), which likewise is strongly associated with γ-GT. METHODOLOGY/PRINCIPAL FINDINGS: Analyses were based on occupational health examinations of more than 15,000 German male workers aged 16-64 years, predominantly from the construction industry. Sociodemographics and other health-related information were collected during the exam. Joint associations of smoking and alcohol consumption or BMI with elevated or log-transformed γ-GT were examined by tabulation and multiple adjusted regression models. Cigarette smoking exerted no effect on γ-GT in teetotalers, but there was a statistically significant effect of smoking among participants with higher alcohol consumption intensity, odds of elevated γ-GT being increased by 24% and 27% per additional 10 cigarettes smoked per day in subjects drinking 61-90 and >90 gram alcohol per day, respectively (P for interaction = 0.039). The interaction was opposite for BMI, where no association was seen in obese subjects, whereas odds of elevated γ-GT were increased by 24% per 10 cigarettes below 25 kg/m(2) (P for interaction = 0.040). This novel interaction was replicable in an independent cohort. CONCLUSION: The evidence for opposite interactions of smoking with alcohol and BMI as determinants of serum γ-GT suggests that different physiological pathways are responsible for the associations between these factors

Quality of life and physical activity in long-term (≥5 years post-diagnosis) colorectal cancer survivors - systematic review

Background: Due to the increasing number of long-term (≥5 years post diagnosis) colorectal cancer survivors, long-term quality of life of these patients is highly relevant. Several studies have reported a positive association between physical activity and quality of life in colorectal cancer survivors, however, so far no systematic review has been published which focuses on long-term colorectal cancer survivors. Material and methods: A systematic review was conducted using the databases PubMed, Web of Science, PsychINFO, and CINAHL. Studies which investigated associations between physical activity and quality of life in long-term colorectal cancer survivors were included. Results and conclusion: Ten articles based on seven studies were identified. Long-term colorectal cancer survivors who were physically active reported better quality of life than long-term survivors who were not physically active. Both, moderate to vigorous physical activity and lower levels like light physical activity were associated with higher quality of life. Most studies assessed the association between physical activity and quality of life cross-sectionally but one prospective study which measured physical activity and quality of life at three different points in time also found associations between physical activity and quality of life. The association between physical activity and quality of life seemed to be stronger among women than among men. The findings of this systematic review support an association between physical activity and quality of life in long-term colorectal cancer survivors. However, the evidence is limited as most studies were based on cross-sectional and observational design

Die Effekte einer Ärzte-Kurzschulung zur Raucherentwöhnung in einer pneumologischen Akutklinik eines Universitätsklinikums

Objective: The objective was to evaluate the effect of a short physician training in smoking cessation on the physicians’ performance of smoking cessation interventions. The effects on patients’ cessation rates were analyzed as well. A further aim was to identify barriers for providing cessation interventions. The study was conducted in an acute care pulmonology department of a German university hospital. Methods: 24 physicians of the pulmonology department of a German university hospital received a two-hour training in smoking cessation. 109 pre- and 89 post-training group patients were compared with regard to the frequencies of received smoking cessation interventions (Ask, Advise, Assist) and three- and six-month abstinence rates. Physicians estimated their intervention frequencies and gave reasons for not providing cessation interventions. Results: In a multivariable analysis (p<0.05), the physicians’ application of “Ask” (OR 3.28, 95% CI 1.13–9.53) and the six-month abstinence rates (OR 2.70, 95% CI 1.24–5.84) were significantly higher in the post-training group. The univariate analysis also showed a significant effect on “Assist” (OR 2.05, 95% CI 1.09–3.87). No significant effect was seen on “Advise to quit”. Physicians overestimated their intervention frequencies and reported the patients’ low motivation to stop, an oncological disease and palliative care situation as barriers to performing smoking cessation. Conclusion: A short physician training in a hospital department of pulmonology increases the use of guideline-based cessation strategies and may improve cessation rates. The findings show that hospital-based strategies such as physician trainings could be useful in the improvement of smoking cessation. Strategies for overcoming barriers for providing smoking cessation interventions are needed.Ziel: Das Ziel war die Evaluation der Effekte einer Ärzte-Kurzschulung zur Raucherentwöhnung auf die Anwendungshäufigkeit der Entwöhnungsstrategien durch die Ärzte. Ebenso wurden die Effekte auf die Abstinenzraten der Patienten untersucht. Außerdem sollten die Barrieren für die Durchführung von Raucherentwöhnungsmaßnahmen ermittelt werden. Die Studie wurde in einer pneumologischen Akutklinik eines deutschen Universitätsklinikums durchgeführt. Methoden: 24 Ärzte erhielten eine zweistündige Schulung zur Raucherentwöhnung. 109 Kontrollgruppenpatienten, die vor der Schulung in der Klinik behandelt wurden, wurden mit 89 nach der Schulung behandelten Studiengruppenpatienten hinsichtlich der Häufigkeit der ärztlichen Raucherentwöhnungsinterventionen (Ask, Advise, Assist) und ihrer Abstinenzraten drei und sechs Monate nach Klinikaufenthalt verglichen. Die Ärzte schätzten ihre Interventionshäufigkeiten und gaben Gründe an, warum sie in manchen Fällen keine Entwöhnungsinterventionen durchführten. Ergebnisse: Die Anwendung von „Ask“ (OR 3.28, 95% KI 1.13–9.53) durch die Ärzte und die Sechsmonats-Abstinenzraten (OR 2.70, 95% KI 1.24–5.84) waren in der Studiengruppe im multivariablen Modell signifikant höher (p<0.05). Bei „Assist“ zeigte nur das univariable Modell einen signifikanten Einfluss der Schulung (OR 2.05, 95% KI 1.09–3.87). Es wurde kein signifikanter Effekt der Schulung auf die Anwendung von „Advise“ festgestellt. Die Ärzte überschätzten ihre Interventionshäufigkeiten und nannten als Gründe für die Nicht-Durchführung einer Raucherentwöhnung eine wahrgenommene geringe Aufhörmotivation der Patienten und das Vorliegen einer onkologischen oder palliativen Krankheitssituation. Fazit: Eine Ärztekurzschulung zur Raucherentwöhnung in einer pneumologischen Akutklinik erhöht den Einsatz von leitlinienbasierten Raucherentwöhnungsstrategien und könnte einen positiven Effekt auf die Abstinenzraten haben. Implikationen: Die Ergebnisse zeigen, dass Krankenhaus-basierte Strategien wie Ärzteschulungen zur Verbesserung der Raucherentwöhnung nützlich sein können. Strategien zur Überwindung von Hindernissen für die Bereitstellung von Maßnahmen zur Raucherentwöhnung sind erforderlich

Patterns of healthcare seeking among people reporting chronic conditions in rural sub-Saharan Africa: findings from a population-based study in Burkina Faso.

OBJECTIVE: Non-communicable diseases are rapidly becoming one of the leading causes of morbidity and mortality in sub-Saharan Africa. Yet, little is known about patterns of healthcare seeking among people with chronic conditions in these settings. We aimed to explore determinants of healthcare seeking among people who reported at least one chronic condition in rural Burkina Faso. METHODS: Data were drawn from a cross-sectional population-based survey conducted across 24 districts on 52 562 individuals from March to June 2017. We used multinomial logistic regression to assess factors associated with seeking care at a formal provider (facility-based care) or at an informal provider (home and traditional treatment) compared to no care. RESULTS: 1124 individuals (2% of all respondents) reported at least one chronic condition. Among those, 22.8% reported formal care use, 10.6% informal care use, and 66.6% no care. The presence of other household members reporting a chronic condition (RRR = 0.57, 95%-CI [0.39, 0.82]) was negatively associated with seeking formal care. Wealthier households (RRR = 2.14, 95%-CI [1.26, 3.64]), perceived illness severity (RRR = 3.23, 95%-CI [2.22, 4.70]) and suffering from major chronic conditions (RRR = 1.54, 95%-CI [1.13, 2.11]) were positively associated with seeking formal care. CONCLUSION: Only a minority of individuals with chronic conditions sought formal care, with important differences due to socio-economic status. Policies and interventions aimed at increasing the availability and affordability of services for early detection and management in peripheral settings should be prioritised

Grasping trapezoidal objects

When grasping rectangular or circular objects with a precision grip the digits close in on the object in opposite directions. In doing so the digits move perpendicular to the local surface orientation as they approach opposite sides of the object. This perpendicular approach is advantageous for accurately placing the digits. Trapezoidal objects have non-parallel surfaces so that moving the digits in opposite directions would make the digits approach the contact surfaces at an angle that is not 90°. In this study we examined whether this happens, or whether subjects tend to approach trapezoidal objects’ surfaces perpendicularly. We used objects of different sizes and with different surface slants. Subjects tended to approach the object’s surfaces orthogonally, suggesting that they aim for an optimal precision of digit placement rather than simply closing their hand as it reaches the object

Liver Enzymes: Interaction Analysis of Smoking with Alcohol Consumption or BMI, Comparing AST and ALT to γ-GT

A detrimental interaction between smoking and alcohol consumption with respect serum γ-glutamyltransferase (γ-GT) has recently been described. The underlying mechanisms remain unknown. The present work aimed to provide further insights by examining similar interactions pertaining to aspartate and alanine transaminase (AST, ALT), routine liver markers less prone to enzyme induction.<0.0001). The interactions all were in the same directions as for γ-GT, i.e. synergistic with alcohol and opposite with BMI.The patterns of interaction between smoking and alcohol consumption or BMI with respect to AST and ALT resembled those observed for γ-GT. This renders enzyme induction a less probable mechanism for these associations, whereas it might implicate exacerbated hepatocellular vulnerability and injury
