The aim of this study was to assess change in temperature, audiometric outcomes and post-operative complications following exposure to different light sources during endoscopic ear surgery.

A total of 64 patients diagnosed with chronic otitis media with central perforation and pure conductive hearing loss underwent endoscopic type 1 tympanoplasty. The patients were randomised into two groups based on the light source used: xenon or light-emitting diode. Temperature was measured using a K type thermocouple at the promontory and round window niche. Mean temperature change with respect to operating time, mean audiometric change, incidence of vomiting in the first 24 hours, vertigo and tinnitus at the end of the first week were observed.

Mean temperature change showed a statistically significant difference with increasing length of operating time with the xenon light source and when the two light sources were compared for a particular time interval. Mean audiometric change showed statistically significant deterioration at higher frequencies (4, 6 and 8 kHz) with the xenon light source but only at 8 kHz for the light emitting diode source. When the mean audiometric change was compared between light sources for a particular frequency, statistical significance was found at 4, 6 and 8 kHz. Post-operative complications were vomiting, vertigo and tinnitus (p-values of 0.042, 0.099 and 0.147, respectively, between two groups).

Light emitting diodes are associated with less significant middle-ear temperature rises and audiometric changes at higher frequencies when compared to xenon light sources. Hence, xenon should be replaced with cooler light sources.

Dysfunctional impulsivity reflects ‘recklessness without deliberation and evaluation of consequences’ and has negative consequences whereas functional impulsivity reflects ‘rapid responding to situational demands in order to maximise one's circumstances’ and often has positive consequences (1).

To examine the functional brain basis of dysfunctional impulsivity in healthy people and in people with schizophrenia.

Thirteen healthy controls and 21 schizophrenia patients (10/21 with serious repetitive violence) underwent fMRI during a Go/ NoGo task. Dysfunctional impulsivity was indexed using the Impulsiveness subscale and functional impulsivity using the Venturesomeness subscale of the Impulsiveness-Venturesomeness-Empathy questionnaire (2).

Violent patients had elevated Impulsiveness scores relative to non-violent patients and controls. Impulsiveness did not correlate significantly with task performance in healthy controls or patients. Impulsiveness, but not Venturesomeness, scores correlated during the NoGO condition with lower activity in the anterior cingulate (AC) in controls, and lower inferior temporal and hippocampal activity in patients.

These findings accord with previously reported associations between reduced hippocampal volume and dysfunctional impulsivity in schizophrenia (3) and, combined with our earlier observations of reduced AC activation during a working memory task in violent antisocial individuals (4), suggest that the influence of dysfunctional impulsivity in antisocial and criminal behaviour is mediated via deficient (inhibitory) functions of the AC and hippocampus.

Migration of mental health professionals is an important phenomenon influencing mental health services of host and donor countries. Data on medical migration in Europe is very limited, particularly in the field of young doctors and psychiatry. To research this hot topic, the European Federation of Psychiatric Trainees (EFPT) conducted the EFPT Brain Drain Survey.

To identify the impact of previous short-term mobility on international migration and to understand characteristics, patterns and reasons of migration.

In this cross-sectional European multicentre study, data were collected from 2281 psychiatric trainees across 33 countries. All participants answered to the EFPT Brain Drain Survey reporting their attitudes and experiences on migration.

Two-thirds of the trainees had not had a short-mobility experience in their lifetime, but those that went abroad were satisfied with their experiences, reporting that these influenced their attitude towards migration positively. However, the majority of the trainees had not had a migratory experience of more than 1 year. Flows showed that Switzerland and United Kingdom have the greatest number of immigrant trainees, whereas Germany and Greece have the greatest number of trainees leaving. ‘'Pull factors'’ were mostly academic and personal reasons, whereas ‘'push factors'’ were mainly: academic and financial reasons. Trainees that wanted to leave the country were significantly more dissatisfied with their income.

The majority of the trainees has considered leaving the country they currently lived in, but a lower percentage has taken steps towards migration.

Although psychoactive substance use disorders (PSUD) belong to the domain of mental health, their management varies greatly among European countries. Furthermore, both the role of psychiatrists and trainees in the treatment of PSUD is not the same for each European country.

Among the context of the European Federation of Psychiatric Trainees (EFPT), the PSUD Working Group has developed a survey that has been spread out between the 15th of august 2015 and 15th of October 2016, at the aim of gathering information about the training in PSUD in Europe, both from Child and Adolescent, and General Adult Psychiatric (CAP and GAP) trainees.

The survey investigated, at European level, the organisation of the PSUD training, trainees satisfaction, attitudes towards people who use psychoactive substances, management of pharmacologic and involvement in common clinical situations.

A 70-items questionnaire regarding the aforementioned objectives was developed, and shared trough an online data-collecting system among European CAP and GAP trainees, with 40 trainees per country filling the survey in at least 25 countries. One national coordinator per country facilitated the delivering of the survey.

A total of 1250 surveys were filled from more than 25 European countries.

Data from the survey will be promptly analysed.

The survey will be the first to explore European psychiatric trainees attitudes and practices about PSUD. Findings from this independent survey may serve in understanding the needs of trainees in the field of substance misuse psychiatry.

To determine trends and impact on outcomes of atrial fibrillation (AF) in patients with pre-existing major depressive disorder(MDD).

While post-AF MDD has been extensively studied, contemporary studies including temporal trends on impact of pre-AF MDD on AF and post-AF outcomes are lacking.

We used Nationwide Inpatient Sample (NIS) from Healthcare Cost and Utilization Project (HCUP) from 2002 to 2012. We identified AF and MDD as primary and secondary diagnosis respectively using validated International Classification of Diseases, 9th Revision, and Clinical Modification (ICD9CM) codes, and used Cochrane-Armitage trend test and multivariate regression to generate adjusted odds ratios (aOR).

We analyzed total of 3,887,827 AF hospital admissions from 2002 to 2012 of which 6.78% had MDD. Proportion of hospitalizations with MDD increased from 4.93% to 14.19% (P-trend < 0.001). Utilization of atrial cardioversion was lower in patients with MDD (34.37% vs. 40.52%, P < 0.001). In-hospital mortality was significantly lower in patients with MDD (aOR0.749; 95% CI 0.664–0.846; P < 0.001) but discharge to specialty care was higher (aOR 1.695; 95%CI 1.650–1.741; P < 0.001). In addition, median length of hospitalization (2.5 vs. 2.13 days; P < 0.001) and median cost of hospitalization (28,246 vs. 22,663; P < 0.001) was higher in hospitalizations with MDD.

Our study displayed an increasing proportion of patients with MDD admitted due to AF in the last decade with lower mortality but higher morbidity post-AF. In addition, there was significantly less utilization of atrial cardioversion in this population along with higher median length and cost of hospitalization. There is a need to explore the reasons behind this disparity in outcomes and atrial cardioversion utilization in order to improve post-AF outcomes in this vulnerable population.

Association between leptin and ghrelin plasma levels and alcohol craving have been found in few studies but they have failed to differentiate this correlation with alcohol withdrawal state.

To research this correlation in a different population and to study this correlation with respect to hyper-excitable state of alcohol withdrawal.

To study levels of leptin and ghrelin in relation with alcohol withdrawal and craving.

Twenty-five indoor patients fulfilling the alcohol dependence criteria were assessed for alcohol withdrawal symptoms and craving. Leptin and ghrelin levels were measured on 1st day, @ the end of 1st week, @ the end of 3rd week of stopping alcohol. Withdrawal was assessed using CIWA-A at day 1 and day 7, craving was assessed using PENN's scale of craving at the end of week 1 and week 3. Control group consisted of 15 first-degree relatives not taking alcohol.

It was found that leptin [t (38) = 2.95, P = 0.005] and ghrelin [t (38) = 2.56, P = 0.015] were significantly higher in alcohol-dependent patients. Levels of hormones had no significant correlation with alcohol withdrawal scores but had positive correlation with craving scores after abstinence.

Leptin and ghrelin, known for balancing the energy homeostasis of body, also seem to play a role in pathways of drug dependence and craving. This relation is independent of stress hormone axis as leptin and ghrelin levels are not correlated with withdrawal scores, which is an indicator of stress hormone axis activation during alcohol withdrawal.

Bipolar disorder (BD) is a psychiatric disorder associated with increased rates of obesity and inflammation. Leptin is an adipokine that is mainly produced by the white adipose tissue in response to insulin. It stimulates the immune system, increasing the production of pro-inflammatory cytokines. There is currently uncertainty regarding possible alterations in peripheral leptin levels across the mood states in BD.

This study comprises a between-group meta-analysis comparing serum and plasma leptin levels in people with BD in mania, depression or euthymia and healthy controls. We conducted a systematic search for all possibly eligible-English and non-English peer-reviewed articles. We calculated the effect size (ES) utilizing Hedges’ adjusted g using random effects.

Eleven studies were included in the meta-analyses, providing data on 1118 participants. Serum and plasma leptin levels were not altered in subjects with BD when compared to healthy controls in mania (g = −0.99, 95% CI −2.43 to 0.43, P = 0.171), in depression (g = 0.17, 95% CI −0.45 to 0.79, P = 0.584), or in euthymia (g = 0.03, 95% CI −0.39 to 0.46, P = 0.882). However, we did observe a stronger association between leptin levels and both age and BMI in patients with BD in euthymia compared to healthy controls, such that the greater the age of the individuals, the greater the difference in leptin levels between BD and controls; and the higher the BMI, the greater the difference in leptin levels between BD and controls.

Our meta-analysis provides evidence that leptin levels are not altered in BD across the mood spectrum compared to healthy controls. The disproportionate increase of leptin levels with increase in BMI in BD speaks in favour of a potential inflammatory role of white adipose tissue in BD and a disproportionate increase of leptin levels with increase in age.

To determine temporal trends, invasive treatment utilization and impact on outcomes of pre-infarction drug abuse (DA) on acute myocardial infarction (AMI) in adults.

DA is important risk factor for AMI. However, temporal trends in drug abuse on AMI hospitalization outcomes in adults are lacking.

We used Nationwide Inpatient Sample (NIS) from Healthcare Cost and Utilization Project (HCUP) from 2002 to 2012. We identified AMI and DA as primary and secondary diagnosis respectively using validated International Classification of Diseases, 9th Revision, and Clinical Modification (ICD9CM) codes, and used the CochraneArmitage trend test and multivariate regression to generate adjusted odds ratios (aOR).

We analyzed total of 7,174,274 AMI hospital admissions from 2002 to 2012 of which 1.67% had DA. Proportion of hospitalizations with DA increased from 5.63% to 12.08% (P trend < 0.001). Utilization of coronary artery bypass grafting (CABG) was lower in patients with DA (7.83% vs. 9.18%, P < 0.001). In-hospital mortality was significantly lower in patients with DA (aOR 0.811; 95% CI 0.693–0.735; P < 0.001) but discharge to specialty care was higher (aOR 1.076; 95% CI 1.025–1.128; P < 0.001). The median cost of hospitalization (40,834 vs. 37,253; P < 0.001) was higher in hospitalizations with DA.

We demonstrate an increasing proportion of adults admitted with AMI have DA over the decade. However, DA has paradoxical association with mortality in adults. DA is associated with lower CABG utilization and higher discharge to specialty care, with a higher mean cost of hospitalization. The reasons for the paradoxical association of DA with mortality and worse morbidity outcomes need to be explored in greater detail.

To determine trends and impact on outcomes of atrial fibrillation (AF) in patients with pre-existing psychosis.

While post-AF psychosis has been extensively studied, contemporary studies including temporal trends on the impact of pre-AF psychosis on AF and post-AF outcomes are largely lacking.

We used Nationwide Inpatient Sample (NIS) from the healthcare cost and utilization project (HCUP) from year's 2002–2012. We identified AF and psychosis as primary and secondary diagnosis respectively using validated international classification of diseases, 9th revision, and Clinical Modification (ICD-9-CM) codes, and used Cochrane–Armitage trend test and multivariate regression to generate adjusted odds ratios (aOR).

We analyzed total of 3.887.827AF hospital admissions from 2002–2012 of which 1.76% had psychosis. Proportion of hospitalizations with psychosis increased from 5.23% to 14.28% (P trend < 0.001). Utilization of atrial-cardioversion was lower in patients with psychosis (0.76%v vs. 5.79%, P < 0.001). In-hospital mortality was higher in patients with Psychosis (aOR 1.206; 95%CI 1.003–1.449; P < 0.001) and discharge to specialty care was significantly higher (aOR 4.173; 95%CI 3.934–4.427; P < 0.001). The median length of hospitalization (3.13 vs. 2.14 days; P < 0.001) and median cost of hospitalization (16.457 vs. 13.172; P < 0.001) was also higher in hospitalizations with psychosis.

Our study displayed an increasing proportion of patients with Psychosis admitted due to AF with higher mortality and extremely higher morbidity post-AF, and significantly less utilization of atrial-cardioversion. There is a need to explore reasons behind this disparity to improve post-AF outcomes in this vulnerable population.

The European Federation of Psychiatric Trainees (EFPT) is an independent Federation of Psychiatric Trainees and represents the consensus of psychiatric trainee's organizations across European countries and advocates for what training should look like, regardless of the country. Spain was one of the last countries to be part of the Association. Finally, and after months of hard work and networking, on September 2015 the Spanish Society of Psychiatry Trainees(SERP), was founded and Spain became a observer member of the EFPT.

One of the main goals of the SERP, is creating a program of clerkships, in both directions, from other trainees to come to Spain, and for Spanish Trainees to go abroad.

Our idea in this poster is to explain a first look of which Hospitals/Units would be appropriate to make a rotation, and to explain the first steps in order to create a database with information about the nightshifts, possible accommodation and other aspects related to the organization. We want to use this poster to present to Europe our new Association.

On September 25 at the National Congress of Psychiatry in Santiago de Compostela, a Group of Spanish trainees founded the SERP, organized the first Board and signed the Founding Amendments.

After two previous failed attempts, finally on 25th September 201; the Spanish Society of Psychiatry Residents (SERP) was founded, an important part of the activity of this company is promoting exchanges between residents of member countries in Spain.

To determine trends and impact on outcomes of acute myocardial infarction (AMI) in patients with pre-existing psychosis.

While post-AMI psychosis has been extensively studied, contemporary studies including temporal trends on impact of pre-AMI Psychosis on AMI and post-AMI outcomes are lacking.

We used Nationwide Inpatient Sample (NIS) from Healthcare Cost and Utilization Project(HCUP) from 2002 to 2012. We identified AMI and psychosis as primary and secondary diagnosis respectively using validated International Classification of Diseases, 9th Revision, and Clinical Modification (ICD9CM) codes, and Cochrane-Armitage trend test and multivariate regression to generate adjusted odds ratios (aOR).

We analyzed total of 7,174,274 AMI hospital admissions from 2002 to 2012 of which 1.77% had psychosis. Proportion of hospitalizations with psychosis increased from 6.94% to 11.85% (P-trend < 0.001). Utilization of percutaneous coronary intervention (PCI) was lower in patients with psychosis (29.98% vs. 40.36%, P < 0.001). Utilization of coronary artery bypass grafting (CABG) was lower in patients with psychosis (8.01% vs. 9.18%, P < 0.001). In-hospital mortality was significantly lower in patients with psychosis (aOR 0.677; 95% CI 0.630–0.727; P < 0.001) but discharge to specialty care higher (aOR 1.870; 95%CI 1.786–1.958; P < 0.001). In addition, median length of hospitalization (3.77 vs. 2.90 days; P < 0.001) was higher in hospitalizations with psychosis.

Our study displayed increasing proportion of patients with psychosis admitted due to AMI in last decade with lower mortality but higher morbidity post-infarction, and significantly less utilization of PCI and CABG. There was also increased length of stay patients with MDD. There is need to explore reasons behind this disparity in outcomes and PCI and CABG utilization to improve post-AMI outcomes in this vulnerable population.

Neuroimaging studies of attention-deficit/hyperactivity disorder (ADHD) have revealed structural deviations of the corpus callosum in children and adolescents. However, little is known about the link between callosal morphology and symptoms of inattention or hyperactivity in adulthood, especially later in life.

We aimed to further expand this understudied field by analyzing a large population-based sample of 280 adults (150 males, 130 females) in their late sixties and early seventies.

We applied a well-validated approach capturing the thickness of the corpus callosum with a high regional specificity at 100 equidistant points. In addition to correlating point-wise callosal thickness with ADHD symptom measures within the whole sample, we tested for sex interactions.

There were significant sex interactions with respect to measures of inattention and hyperactivity, with follow-up analyses revealing significant negative correlations in males (see Fig. 1 – Top). In contrast, there were positive correlations with respect to hyperactivity only in females (see Fig. 1 – Bottom).

A thinner corpus callosum may be associated with fewer fibers or less myelination. Thus, the negative correlations, as observed in males, suggest an impaired inter-hemispheric communication necessary to sustain motor control and attention, which may contribute to symptoms of hyperactivity, impulsivity and/or inattention. The functional relevance and underlying mechanisms of the positive correlations, as detected in females, remain to be resolved.
