Neurotoxic effects of alcohol consumption are well-known. There is plenty of literature on frontal lobe impairment on the behavioral and structural brain imaging level. However, only few functional imaging studies investigated altered neural patterns and even less abstinence-related neural recovery. Here, we investigated if frontal lobe activity tends to normalize in patients that remain successfully abstinent.
In a cross-sectional design three patient groups (acute withdrawal, detoxified, abstinent) and healthy controls (each n = 20) performed a phonological and semantical verbal fluency task (VFT) while brain activity was measured with near-infrared spectroscopy (NIRS).
First, for the phonological condition patients in the acute withdrawal phase and also detoxified patients showed less fluency-related frontal lobe activation compared to controls despite equal performance. Second, significant linear trend effects from withdrawal patients over detoxified and abstinent patients up to healthy controls indicated more normal activation patterns in the abstinent group that did not differ from the controls. In the detoxified group brain activation increased with time since detoxification.
Our results support the assumption of an increase in frontal brain activity from alcohol dependency over abstinence up to normal functioning. Longitudinal studies are needed to further elucidate recovery processes in alcohol dependency.
Increasing research interest is focussing also on Quality of Life (QoL) in substance dependent individuals. QoL-assessments have been acknowledged as promising measurements in order to evaluate drug treatment programs.
A prospective, randomized, double-blind, double-dummy, cross-over study design was used in order to compare methadone and slow-release morphine maintenance on patients´ QoL. Sixty-four participants were randomized between two treatment groups receiving either slow-release morphine capsules for 7 weeks followed by methadone oral solution for another 7 weeks (group A), or vice versa (group B). At baseline, week 7 and week 14 QoL status was evaluated using the German version of the Lancashire Quality of Life Profile.
A significant time effect with respect to the domains: general state of health (0.018), mental health (p=0.001), general well-being (p<0.001), leisure time at home (p=0.032) and leisure time out of home (p=0.008). Our findings did not show any statistically significant differences between between the two treatment groups in any Quality of Life scores at week 7 and 14. At the end of study phase (week 14) group A showed significant increases in the domains general well-being (0.010), leisure time at home (p=0.014). Significant improvements for group B were assessed with regard to general well-being (p=0.003), mental health (p=0.003) and general state of health (p=0.017).
The development of treatment programs should focus also on the patients´ subjective perspective. According to our findings agonistic opioid maintenance treatment yields not only to treatment response but also to improvements in patients quality of life.
The effect of treatment (28 days) with zopiclone, triazolam, flunitrazepam and placebo on sleep quality and daytime well-being was proven in a randomised, double-blind, parallel group, multicentre study in private practice. Results of an exploratory statistic of treatment efficacy in a subgroup of 1,291 patients suffering from insomnia are presented. Patients met the following criteria: insomnia lasting at least four weeks and the presence of at least two of the following: 1) sleep latency ≥ 45 minutes, 2) total sleep time ≤ 6 hours, and 3) nocturnal awakening ≥3 times. Treatment efficacy was assessed according to the following factors: either a shortening of sleep latency by at least 15 minutes, or prolongation of total sleep time by at least 20%, or reduction of the number of nocturnal awakenings to three or less and a refreshed feeling in the morning as well as no impairment in daytime well-being due to tiredness or anxiety. The total response rate was markedly higher with zopiclone (42.3%; p = 0.0003) than with placebo (29.0%). Triazolam (36.6%; p = 0.0905) and flunitrazepam (33.1%; p = 0.3401) were also more effective than the placebo, but they both tended to have a lower response rate than with zopiclone (p = 0.1199 and 0.0151, respectively). Total response was found to be essentially a reflection of the response of the socially important parameter of daytime well-being. These results suggest that zopiclone is more effective in the treatment of insomnia than either triazolam or flunitrazepam. Since the response of daytime well-being to therapy was generally poor, this parameter embodies the next main therapeutic challenge in the treatment of patients with insomnia.
The article examines infection with viral hepatitis A, B, and C and socio-ethnic factors in a population of injection drug users seeking treatment. The study was conducted between 2001 and 2003 in a rural German hospital; selected sociodemographic and drug-related data as well as a serology for hepatitis A, B and C were obtained from 1499 patients. Statistical analyses were performed by univariate analysis of variance and post-hoc Scheffé tests or with the c2-test and Bonferroni-adjustment. Ethnic minority patients manifested a more severe course of addiction and showed a higher frequency of infection with hepatitis A, B, and C. Low-threshold culture sensitive drug user treatment programs should be implemented and evaluated.
A proinflammatory state in a subgroup of depressed patients has been reported repeatedly (e.g. increased interleukin-6 and tumour necrosis factor-alpha). COX-2 inhibitors down-regulate increased inflammatory markers and are therefore investigated as an add-on therapy in depression. Proinflammatory cytokines and/or kynurenine metabolites may predict the outcome of treatment with COX-2 inhibitors.
To prove or disapprove the hypothesis of a better therapy response in the group of add-on celecoxib to sertraline, particularly in patients with a more pronounced proinflammatory state at baseline. The aim is to find a biological predictor (cytokines and/or kynurenine metabolites) for treatment outcome.
This is a dual-center, randomized, double-blind, placebo-controlled, parallel group phase IIa study. It investigates the mean change in clinical outcome and in serum cytokine and kynurenine levels from baseline to endpoint (week 6) in patients with major depression (HAMD-17 ≥ 22) treated with sertraline plus celecoxib versus sertraline plus placebo for six weeks. 51 depressed patients of both gender, aged between 18 and 60 years without any recent inflammatory disease were enrolled. The study comprises six study visits (6x ratings, 3x blood collections) during six weeks of treatment and a follow-up visit 10 weeks after baseline. Cytokines were measured by Enzyme-linked Immunosorbent Assay (ELISA), kynurenine and its metabolites by High Performance Liquid Chromatography (HPLC).
Results and Conclusion
The study was completed quite recently and the results are in progress.
Previous research revealed substantial relations between the experience of childhood adversities and the development of borderline personality disorders (BPD) in adulthood. However, research about antecedents of adolescent BPD is still in its beginnings. Moreover, there is an ongoing controversy regarding transgenerational effects of childhood adversities and potential mediators.
We aim to investigate transgenerational effects of parental childhood experiences on the development of adolescent BPD within the next generation. Hereby, we are focusing on the investigation of differential effects of maternal and paternal experiences of childhood adversities on adolescent BPD and on underlying mechanisms.
We consecutively recruited 91 female inpatients (Mage = 15.6 years) from the Department of Child and Adolescent Psychiatry, University Hospital Heidelberg, as well as 87 mothers and 59 fathers. Childhood adversities were assessed for parents and adolescents with the German Childhood Experiences of Care and Abuse Questionnaire, adolescent BPD by means of structured clinical interviews (SKID II).
Our results are in favor of a transgenerational effect of parental childhood adversities on the development of adolescent BPD. This effect turned out to be stronger for paternal than for maternal childhood adversities. Moreover, paternal childhood adversities revealed to be related to experiences of childhood adversities within the next generation.
Our results underline the importance of taking the family environment into consideration when developing prevention and treatment programs for adolescent BPD.
The aim of this analysis is to describe medication adherence, and treatment persistence, in adults with attention deficit/hyperactivity disorder (ADHD) treated for 24 weeks with extended release methylphenidate (MPH-ER). Additionally, patient-, disorder- and treatment-related factors associated with adherence and persistence will be identified.
Post-hoc analysis of the active treatment group of a placebo-controlled, randomised, 24 week trial with MPH-ER with univariate description and multiple logistic regression models and Hosmer and Lemeshow tests.
In the sample of 241 adults with ADHD (mean age of 35.2 ± 10.1 years), 9.4% of the patients were non-adherent, taking less than 80% of the dispensed medication. Factors associated with non-adherence included age < 25 years, education level lower than secondary education, lacking family history of ADHD, lower ADHD baseline severity and lower self- and observer-rated medication efficacy. Lacking family history of ADHD, lower education level and lower self-rated medication efficacy, predicted non-adherence with a prediction accuracy of 16%. Seventeen percent of the patients discontinued early with most discontinuing within the first five weeks of the MPH-ER titration phase. Mean persistence in the discontinuing group was 63.4 ± 49.4 days. Factors associated with discontinuation included male gender, lower education level, lacking family history of ADHD and lower self- and observer-rated medication efficacy. Treatment non-response, male gender and lower education level predicted treatment discontinuation with a prediction accuracy of 22.7%.
Male adults without relatives with ADHD, with lower educational level and lower self- and observer-rated medication efficacy, who are newly treated with MPH-ER, are at increased risk of non-adherence and treatment discontinuation. Patients are at increased risk of treatment discontinuation during the medication titration phase.
A proinflammatory state in a subgroup of depressed patients has been reported repeatedly, for example an increase in interleukin-6 and tumour necrosis factor-a is well documented. Treatment with COX-2 inhibitors down-regulate increased inflammatory markers. Therefore an adjunctive treatment of depression with COX-2 in combination with an antidepressant might lead to a better clinical outcome.
To prove or disapprove the hypothesis of a better clinical outcome in the group with add-on celecoxib to sertraline in terms of improvement of HamD-17 and MADRS scores from baseline to endpoint.
This is a dual-center, randomized, double-blind, placebo-controlled, parallel group phase IIa study to investigate the mean change in clinical outcome and in serum expression of inflammation markers from baseline to endpoint (week 6) in patients with major depression (HAMD-17 ≥ 22) treated with celecoxib in combination with sertraline compared to sertraline combined with placebo. 51 depressed patients of both gender, aged between 18 and 60 without any recent inflammatory related disease were enrolled. The study comprises six study visits (6x ratings including HAMD-17 and MADRS, 3x blood collections) during six weeks of treatment and a follow-up visit 10 weeks after baseline.
Results and Conclusion
The study was completed quite recently and the results are in progress.
The deviation from thermodynamic equilibrium of the ion velocity distribution functions (VDFs), as measured by the Magnetospheric Multiscale (MMS) mission in the Earth’s turbulent magnetosheath, is quantitatively investigated. Making use of the unprecedented high-resolution MMS ion data, and together with Vlasov–Maxwell simulations, this analysis aims at investigating the relationship between deviation from Maxwellian equilibrium and typical plasma parameters. Correlations of the non-Maxwellian features with plasma quantities such as electric fields, ion temperature, current density and ion vorticity are found to be similar in magnetosheath data and numerical experiments, with a poor correlation between distortions of ion VDFs and current density, evidence that questions the occurrence of VDF departure from Maxwellian at the current density peaks. Moreover, strong correlation has been observed with the magnitude of the electric field in the turbulent magnetosheath, while a certain degree of correlation has been found in the numerical simulations and during a magnetopause crossing by MMS. This work could help shed light on the influence of electrostatic waves on the distortion of the ion VDFs in space turbulent plasmas.
Item 9 of the Patient Health Questionnaire-9 (PHQ-9) queries about thoughts of death and self-harm, but not suicidality. Although it is sometimes used to assess suicide risk, most positive responses are not associated with suicidality. The PHQ-8, which omits Item 9, is thus increasingly used in research. We assessed equivalency of total score correlations and the diagnostic accuracy to detect major depression of the PHQ-8 and PHQ-9.
We conducted an individual patient data meta-analysis. We fit bivariate random-effects models to assess diagnostic accuracy.
16 742 participants (2097 major depression cases) from 54 studies were included. The correlation between PHQ-8 and PHQ-9 scores was 0.996 (95% confidence interval 0.996 to 0.996). The standard cutoff score of 10 for the PHQ-9 maximized sensitivity + specificity for the PHQ-8 among studies that used a semi-structured diagnostic interview reference standard (N = 27). At cutoff 10, the PHQ-8 was less sensitive by 0.02 (−0.06 to 0.00) and more specific by 0.01 (0.00 to 0.01) among those studies (N = 27), with similar results for studies that used other types of interviews (N = 27). For all 54 primary studies combined, across all cutoffs, the PHQ-8 was less sensitive than the PHQ-9 by 0.00 to 0.05 (0.03 at cutoff 10), and specificity was within 0.01 for all cutoffs (0.00 to 0.01).
PHQ-8 and PHQ-9 total scores were similar. Sensitivity may be minimally reduced with the PHQ-8, but specificity is similar.
In 2013, the national surveillance case definition for West Nile virus (WNV) disease was revised to remove fever as a criterion for neuroinvasive disease and require at most subjective fever for non-neuroinvasive disease. The aims of this project were to determine how often afebrile WNV disease occurs and assess differences among patients with and without fever. We included cases with laboratory evidence of WNV disease reported from four states in 2014. We compared demographics, clinical symptoms and laboratory evidence for patients with and without fever and stratified the analysis by neuroinvasive and non-neuroinvasive presentations. Among 956 included patients, 39 (4%) had no fever; this proportion was similar among patients with and without neuroinvasive disease symptoms. For neuroinvasive and non-neuroinvasive patients, there were no differences in age, sex, or laboratory evidence between febrile and afebrile patients, but hospitalisations were more common among patients with fever (P < 0.01). The only significant difference in symptoms was for ataxia, which was more common in neuroinvasive patients without fever (P = 0.04). Only 5% of non-neuroinvasive patients did not meet the WNV case definition due to lack of fever. The evidence presented here supports the changes made to the national case definition in 2013.
Different diagnostic interviews are used as reference standards for major depression classification in research. Semi-structured interviews involve clinical judgement, whereas fully structured interviews are completely scripted. The Mini International Neuropsychiatric Interview (MINI), a brief fully structured interview, is also sometimes used. It is not known whether interview method is associated with probability of major depression classification.
To evaluate the association between interview method and odds of major depression classification, controlling for depressive symptom scores and participant characteristics.
Data collected for an individual participant data meta-analysis of Patient Health Questionnaire-9 (PHQ-9) diagnostic accuracy were analysed and binomial generalised linear mixed models were fit.
A total of 17 158 participants (2287 with major depression) from 57 primary studies were analysed. Among fully structured interviews, odds of major depression were higher for the MINI compared with the Composite International Diagnostic Interview (CIDI) (odds ratio (OR) = 2.10; 95% CI = 1.15–3.87). Compared with semi-structured interviews, fully structured interviews (MINI excluded) were non-significantly more likely to classify participants with low-level depressive symptoms (PHQ-9 scores ≤6) as having major depression (OR = 3.13; 95% CI = 0.98–10.00), similarly likely for moderate-level symptoms (PHQ-9 scores 7–15) (OR = 0.96; 95% CI = 0.56–1.66) and significantly less likely for high-level symptoms (PHQ-9 scores ≥16) (OR = 0.50; 95% CI = 0.26–0.97).
The MINI may identify more people as depressed than the CIDI, and semi-structured and fully structured interviews may not be interchangeable methods, but these results should be replicated.

Mild behavioral impairment (MBI) describes later life acquired, sustained neuropsychiatric symptoms (NPS) in cognitively normal individuals or those with mild cognitive impairment (MCI), as an at-risk state for incident cognitive decline and dementia. We developed an operational definition of MBI and tested whether the presence of MBI was related to caregiver burden in patients with subjective cognitive decline (SCD) or MCI assessed at a memory clinic.
MBI was assessed in 282 consecutive memory clinic patients with SCD (n = 119) or MCI (n = 163) in accordance with the International Society to Advance Alzheimer's Research and Treatment – Alzheimer's Association (ISTAART–AA) research diagnostic criteria. We operationalized a definition of MBI using the Neuropsychiatric Inventory Questionnaire (NPI-Q). Caregiver burden was assessed using the Zarit caregiver burden scale. Generalized linear regression was used to model the effect of MBI domains on caregiver burden.
While MBI was more prevalent in MCI (85.3%) than in SCD (76.5%), this difference was not statistically significant (p = 0.06). Prevalence estimates across MBI domains were affective dysregulation (77.8%); impulse control (64.4%); decreased motivation (51.7%); social inappropriateness (27.8%); and abnormal perception or thought content (8.7%). Affective dysregulation (p = 0.03) and decreased motivation (p=0.01) were more prevalent in MCI than SCD patients. Caregiver burden was 3.35 times higher when MBI was present after controlling for age, education, sex, and MCI (p < 0.0001).
MBI was common in memory clinic patients without dementia and was associated with greater caregiver burden. These data show that MBI is a common and clinically relevant syndrome.
Although many pests constrain rice production, weeds are considered to be the major barrier to achieving optimal yields. A predictive model based on naturally occurring mixed-species infestations in the field would enable growers to target the specific weed group that is the greatest contributor to yield loss, but as of now no such models are available. In 2013 and 2014, two empirical hyperbolic models were tested using the relative cover at canopy closure of groups of weed species as independent variables: grasses, sedges, broadleaves, grasses and sedges combined, grasses and broadleaves combined, and all weed species combined. Models were calibrated using data from experiments conducted at the California Rice Experiment Station, in Biggs, CA, and validated across four sites over 2 years, for a total of 7 site-year combinations. Of the three major weed groups, grasses, sedges, and broadleaves, the only groups positively related to yield loss in the multispecies infestation were grasses. At the model calibration site, grasses and sedges combined best predicted yield loss (corrected Akaike information criterion [AICc]=−21.5) in 2013, and grasses alone best predicted yield loss (AICc=−19.0) in 2014. Across the validation sites, the model using grasses and sedges combined was the best predictor in 5 out of 7 site-years. Accuracy of the predicted values at the model validation sites ranged from 6% mean average error to 17% mean average error. No single model and set of parameters accurately predicted losses across all years and locations, but relative cover of grasses and sedges combined at canopy closure was the best estimate over the most sites and years.
Over the last 10 yr, California has experienced a series of ever-worsening droughts. Rice, traditionally a flooded crop, has come under increasing scrutiny with respect to its water use, leading to proposals to evaluate alternative irrigation systems. For growers, weed competition is one of the most limiting factors to maintaining high yields, so understanding the shifts among species in weed communities under the proposed alternative irrigation systems is vital. A field study was conducted from 2012 to 2014 to compare weed population and growth dynamics with three irrigation systems: (1) a conventional water-seeded control system (WS-Control), with a permanent flood of 10 to 15 cm from planting until 1 mo prior to harvest; (2) a water-seeded alternate wet and dry system (WS-AWD), with the field flooded from planting until canopy closure, after which floodwater was allowed to subside and the field was reflooded when the soil volumetric water content reached 35%; and (3) a drill-seeded alternate wet and dry system (DS-AWD), with rice drill seeded and then flush irrigated to establish the crop, after which the field was flooded until canopy closure and then underwent an alternate wet and dry (AWD) treatment similar to WS-AWD. In the AWD treatments, there were two drying periods, neither of which occurred after the heading stage. The dynamics of major weed species were evaluated using plant density counts (2012) and relative cover and biomass (2013 and 2014). Grasses (sprangletop and watergrass species) dominated the DS-AWD system; sedges, broadleaves, and grasses dominated both WS systems. The WS-AWD system increased smallflower umbrella sedge relative cover at canopy closure, relative dry weight at harvest, and percent frequency when compared with the WS-Control system. Yields did not differ across treatments when weeds were controlled (P>0.05); in the absence of herbicides, yields in the WS-AWD were equivalent to the WS-Control (ranging from 40 to 65% of the herbicide-treated yields) and zero in the DS-AWD due to weed pressure.
Introduction: Point of care ultrasound has become an established tool in the initial management of patients with undifferentiated hypotension. Current established protocols (RUSH, ACES, etc) were developed by expert user opinion, rather than objective, prospective data. We wished to use reported disease incidence to develop an informed approach to PoCUS in hypotension using a “4 F’s” approach: Fluid; Form; Function; Filling. Methods: We summarized the incidence of PoCUS findings from an international multicentre RCT, and using a modified Delphi approach incorporating this data we obtained the input of 24 international experts associated with five professional organizations led by the International Federation of Emergency Medicine. The modified Delphi tool was developed to reach an international consensus on how to integrate PoCUS for hypotensive emergency department patients. Results: Rates of abnormal PoCUS findings from 151 patients with undifferentiated hypotension included left ventricular dynamic changes (43%), IVC abnormalities (27%), pericardial effusion (16%), and pleural fluid (8%). Abdominal pathology was rare (fluid 5%, AAA 2%). After two rounds of the survey, using majority consensus, agreement was reached on a SHoC-hypotension protocol comprising: A. Core: 1. Cardiac views (Sub-xiphoid and parasternal windows for pericardial fluid, cardiac form and ventricular function); 2. Lung views for pleural fluid and B-lines for filling status; and 3. IVC views for filling status; B. Supplementary: Additional cardiac views; and C. Additional views (when indicated) including peritoneal fluid, aorta, pelvic for IUP, and proximal leg veins for DVT. Conclusion: An international consensus process based on prospectively collected disease incidence has led to a proposed SHoC-hypotension PoCUS protocol comprising a stepwise clinical-indication based approach of Core, Supplementary and Additional PoCUS views.
Introduction: Point of care ultrasound (PoCUS) provides invaluable information during resuscitation efforts in cardiac arrest by determining presence/absence of cardiac activity and identifying reversible causes such as pericardial tamponade. There is no agreed guideline on how to safely and effectively incorporate PoCUS into the advanced cardiac life support (ACLS) algorithm. We consider that a consensus-based priority checklist using a “4 F’s” approach (Fluid; Form; Function; Filling), would provide a better algorithm during ACLS. Methods: The ultrasound subcommittee of the Australasian College for Emergency Medicine (ACEM) drafted a checklist incorporating PoCUS into the ACLS algorithm. This was further developed using the input of 24 international experts associated with five professional organizations led by the International Federation of Emergency Medicine. A modified Delphi tool was developed to reach an international consensus on how to integrate ultrasound into cardiac arrest algorithms for emergency department patients. Results: Consensus was reached following 3 rounds. The agreed protocol focuses on the timing of PoCUS as well as the specific clinical questions. Core cardiac windows performed during the rhythm check pause in chest compressions are the sub-xiphoid and parasternal cardiac views. Either view should be used to detect pericardial fluid, as well as examining ventricular form (e.g. right heart strain) and function, (e.g. asystole versus organized cardiac activity). Supplementary views include lung views (for absent lung sliding in pneumothorax and for pleural fluid), and IVC views for filling. Additional ultrasound applications are for endotracheal tube confirmation, proximal leg veins for DVT, or for sources of blood loss (AAA, peritoneal/pelvic fluid). Conclusion: The authors hope that this process will lead to a consensus-based SHoC-cardiac arrest guideline on incorporating PoCUS into the ACLS algorithm.
Glacier response to climate forcing can be heterogeneous and complex, depending on glacier system characteristics. This article presents the decadal evolution of the Tsarmine Glacier (Swiss Alps), a very small and heavily debris-covered cirque glacier located in the Alpine periglacial belt. Archival aerial photogrammetry and autocorrelation of orthophotos were used to compute surface elevation, volume and geodetic mass changes, as well as horizontal displacement rates for several periods between 1967 and 2012. A GPR survey allowed us to investigate glacier thickness (15 m mean) and volume (4 × 106 m3) in 2015 and to anticipate its future evolution. Different dynamics occurred in recent decades because of the heterogeneous surface characteristics. The climate-sensitive upper debris-free zone contrasts with the progressively stagnant heavily debris-covered glacier tongue. Between 1967 and 2012, the glacier lost 1/3 of its initial volume (2 × 106 m3). The average mass balance stabilised at ~−0.3 m w.e. a−1 since 1999. Compared with other local glaciers, the Tsarmine Glacier shows a particular decadal behaviour both in time (divergence of mass balance since the 2000s) and space (inverted ablation pattern). This might be explained by the combined influence of debris cover, shadow, snow redistribution and permafrost conditions on this very small glacier.
