Introduction
Bipolar disorder (BD) is a chronic mental disorder characterized by mood instability1. BD is further related to neurocognitive and functional disruptions that remain remarkably stable even when patients are euthymic, leading to poor well-being and quality of life. Mindfulness means paying attention on purpose, in the present moment, and involves different facets such as observing, describing, acting with awareness, non-judging and non-reacting of inner experience. It remains unclear whether mindfulness and its specific facets are differentially associated with different aspects of attention and trait impulsivity in individuals with BD.
ObjectivesTo examine associations between different mindfulness facets, and different aspects of attention and trait impulsivity in BD.
MethodsThis study was approved by the Hospital Clínic Ethics and Research Board (HCB/2017/0432). After informed consent, 94 outpatients, M age = 45.57, SD = 9.8, range 19-61 years, 41.5% Male, 63.8% BD-I according to DSM-5 criteria, in partial or total remission based on Young Mania Rating Scale (YMRS; M = 1.81, SD = 2.11) and Hamilton Depression Rating Scale (HDRS; M = 5.46, SD = 3.71) were enrolled in this study. Participants were evaluated using the Five Facet Mindfulness Questionnaire (FFMQ) to assess Mindfulness, the Trail Making Test (TMT-A) and the Conner’s Continuous Performance test (CPT-II) to assess Attention, and the Barratt Impulsiveness Scale (BIS-11) to assess Impulsivity. Pearson correlations were performed, and statistical significance was evaluated two-sided at the 5% threshold.
ResultsMindfulness-Describing was negatively associated with Cognitive and Non-Planning Impulsivity (r = -.43 and -.28, p < .001), Mindfulness-Acting with Awareness was negatively associated with Cognitive, Motor and Non-Planning Impulsivity (r = -.27 to -.45, p < .001), Mindfulness Non-Judging (r = -.33 and -.34, p < .001) and Non-Reacting (r = -.30 and -.46, p < .001) of inner experience were negatively associated with Cognitive and Motor Impulsivity. No associations were found between neither Mindfulness nor Impulsivity with any aspects of Attention.
ConclusionsPreliminary findings suggest that better performance in specific facets of mindfulness (describing, acting with awareness, non-judging or reacting of inner experience) may be related to a decrease in different aspects of trait impulsivity. Further longitudinal and interventional research is needed on underlying mechanisms. Nonetheless, our study suggests the need for including mindfulness-based approaches to improve behavioral and functional outcomes for those with BD.

Introduction
Bipolar disorder (BD) is a chronic and recurrent mental condition characterized by mood fluctuations between hypomania or mania and depression, with high level of burden and mortality rates (Hayes et al., 2015). Subsyndromal mood symptoms, including residual depression, mania and/or anxiety, are major risk factors for episodic relapses after mood stabilisation (Samalin et al., 2016). A psychological protective mechanism against the occurrence of these maladaptative mood symptoms is dispositional mindfulness (DM). DM refers to paying purposeful attention to present moment experiences with a curious, non-judgmental and accepting attitude (Radford et al., 2014). DM has been barely assessed in BD and there is very little evidence on the relationship between DM, residual mood symptoms and quality of life
ObjectivesTo explore associations between DM, residual mood symptoms and quality of life in individuals with BD
MethodsAfter informed consent, a total of 94 adults (Mean age= 45.57 years, 41.50% Male) with diagnosis of BD according to DSM-5 criteria, in full or partial remission,were recruited from the Bipolar and Depressive Disorders Unit at the Hospital Clinic of Barcelona. The ethical committee approved this study. Dispositional mindfulness was assessed using the Mindfulness Attention Awareness Scale (MAAS).The presence of residual depressive symptoms was assessed with the Hamilton Depression Rating Scale (HDRS), residual mania symptoms were assessed with the Young Mania Rating Scale(YMRS), and anxiety symptoms were assessed with the Hamilton Anxiety Rating Scale (HAM-A). The subjective quality of life was assessed with the Quality of Life in Bipolar Disorder Questionnaire (QoL-BD). Pearson correlations were carried out and the level of significance was set at p<0.05
ResultsDM was negatively related to residual depressive symptoms (r= -0.283; p=0.009) and to anxiety symptoms (r=-0.345; p<0.001), and positively related to quality of life (r=0.433; p<0.001), but not related to residual manic symptoms in BD
ConclusionsOur preliminary data suggest that BD patients with higher levels of DM may experience less depressive and anxiety subsyndromal symptoms and perceived higher quality of life. No associations were detected regarding mania symptoms. These findings support the use of mindfulness training as an adjunct therapy to pharmacotherapy to reduce residual mood symptoms and improve quality of life in patients with BD

Recent research has shown that religious individuals are much more resistant to utilitarian modes of thinking than their less religious counterparts, but the reason for this is not clear. We propose that a meta-ethical belief that morality is rooted in inviolable divine commands (i.e., endorsement of Divine Command Theory) may help explain this finding. We present a novel 20-item scale measuring a belief that morality is founded on divine authority. The scale shows good internal reliability and convergent and discriminant validity. Study 1 found that this scale fully mediated the relationship that various religiosity measures had with a deontological thinking style in our sample of American adults. It also accounted for the link between religiosity and social conservative values. Furthermore, the relationship between the scale and these outcome variables held after statistically controlling for variables related to actively open-minded thinking and the Big Five. Study 2 replicated the results using naturalistic moral dilemmas that placed deontological and utilitarian concerns in conflict, and showed that the results of Study 1 cannot be explained by differences in moral foundations (e.g., concern for authority more generally) or differences in the perceived function of rules. Quite the contrary, endorsement of the divine origins of morality fully mediated the relationship religiosity had with the so-called “binding” foundations (i.e., Loyalty, Authority, and Sanctity). Our findings highlight the importance of meta-ethical beliefs for understanding individual differences in moral judgment.

Introduction
Bipolar disorder is a serious mental disorder. Although bipolar disorder I (BDI) might seem to have a more complex evolution and severe prognosis than bipolar disorder II (BDII) because of cross-sectional symptom severity, BDII has a high episode frequency, high rates of psychiatric comorbidities and recurrent suicidal behaviours that impair functioning and quality of life.
ObjectivesTo explore whether there are differences between patients with BDI and BDII concerning sociodemographic and clinical variables of interest.
MethodsA sample of 407 euthymic patients with bipolar disorder (307 BDI and 100 BDII) being age 18 or older was recruited from the Bipolar and Depressive Disorders Unit of the Hospital Clinic of Barcelona. Sociodemographic and clinical variables were collected through the administration of semi-structured interview and clinical scales. Differences between groups in these variables were analysed using the Mann-Whitney U and Chi-square tests, as appropriate. The level of significance was set at p <0.05.
ResultsWe found statistically significant differences between both groups. Patients with BD II were older (p<0.001), presented a longer illness duration (p=0,001) and a greater subsyndromal depressive symptomatology (p=0,010). Patients with BDI had a higher number of previous hospitalizations (p<0,001) and higher rates of psychotic symptoms (p<0,001) even during the first episode (p<0,001).
ConclusionsOur data suggests that clinical differences exist between both bipolar subtypes. The episodes may be more serious, with a greater presence of a history of psychosis, and require more hospitalizations in BDI patients. In the BDII group, persistent subsyndromal symptoms may predominate, especially of the depressive pole.

Introduction
Bipolar Disorder (BD) is a severe mental disorder with a high genetic load, in which is relevant to identify potential differences in affective temperaments between both diagnostic subtypes.
ObjectivesTo find differences between BDI and BDII patients in affective temperaments evaluated by Temperament Evaluation of the Memphis, Pisa, Paris, and San Diego TEMPS-A.
MethodsA sample of 407 euthymic patients with diagnosis of bipolar disorder type I (BDI= 307) or type II (BDII= 100) according to DSM-IV-TR criteria being age 18 or older was recruited from the Bipolar and Depressive Disorders Unit of the Hospital Clinic of Barcelona. Five affective temperaments were evaluated using the TEMPS-A. It was initially verified that the scores of these temperaments do not fulfil the assumption of normality by means of tests. Differences in means were estimated using Mann-Whitney U and Chi square tests (p <0.05) as appropriate, and ANCOVA controlling the effect of confounding variables.
ResultsData revealed that patients with BD II had significantly higher scores in four affective temperaments: dysthymic, cyclothymic, irritable and anxious compared to BDI. After controlling the most relevant moderating variables, BDII patients continued to show higher scores in irritable temperament .
ConclusionsBDII patients present a more irritable temperament than BDI (p=0,037), which can affect the course and management of the disease. It could be suggested that presenting higher scores of these temperaments could be associated with BDII and further studies are needed to replicate this finding since it might help the clinicians in early phases to guide in the diagnostic process.

Objectives
To report an extremely rare case of malleoincudal osteoma that led to conductive hearing loss despite an unusually normal otomicroscopic appearance, and to highlight the usefulness of costal cartilage for ossicular chain reconstruction after tumour removal.
Case reportA 37-year-old woman presented with a 2-year history of progressive, right-sided hearing loss. Physical examination revealed a normal tympanic membrane. Pure tone audiometry showed a right-sided conductive hearing loss. High-resolution computed tomography revealed a right-sided epitympanic mass arising from the malleus head and contiguous with the incus. The patient underwent a closed mastoido-epitympanectomy. The malleus head and the incus with associated malleoincudal osteoma were removed. Ossicular chain reconstruction using costal cartilage was performed at the time of tumour removal.
ConclusionThe possibility of a middle-ear osteoma must be considered in cases of unilateral and progressive conductive hearing loss with a normal otomicroscopic appearance in patients with no history of ear infection, trauma or prior surgery, and with no family history of hearing loss. Surgical treatment is indicated in cases of significant conductive hearing loss. To our knowledge, this is the first case report of malleoincudal osteoma in which the ossicular chain was reconstructed using costal cartilage.

Background
Research on post-traumatic stress disorder (PTSD) course finds a substantial proportion of cases remit within 6 months, a majority within 2 years, and a substantial minority persists for many years. Results are inconsistent about pre-trauma predictors.
MethodsThe WHO World Mental Health surveys assessed lifetime DSM-IV PTSD presence-course after one randomly-selected trauma, allowing retrospective estimates of PTSD duration. Prior traumas, childhood adversities (CAs), and other lifetime DSM-IV mental disorders were examined as predictors using discrete-time person-month survival analysis among the 1575 respondents with lifetime PTSD.
Results20%, 27%, and 50% of cases recovered within 3, 6, and 24 months and 77% within 10 years (the longest duration allowing stable estimates). Time-related recall bias was found largely for recoveries after 24 months. Recovery was weakly related to most trauma types other than very low [odds-ratio (OR) 0.2–0.3] early-recovery (within 24 months) associated with purposefully injuring/torturing/killing and witnessing atrocities and very low later-recovery (25+ months) associated with being kidnapped. The significant ORs for prior traumas, CAs, and mental disorders were generally inconsistent between early- and later-recovery models. Cross-validated versions of final models nonetheless discriminated significantly between the 50% of respondents with highest and lowest predicted probabilities of both early-recovery (66–55% v. 43%) and later-recovery (75–68% v. 39%).
ConclusionsWe found PTSD recovery trajectories similar to those in previous studies. The weak associations of pre-trauma factors with recovery, also consistent with previous studies, presumably are due to stronger influences of post-trauma factors.

Shiga toxin-producing Escherichia coli (STEC) is a known food pathogen, which main reservoir is the intestine of ruminants. The abundance of different STEC lineages in nature reflect a heterogeneity that is characterised by the differential expression of certain genotypic characteristics, which in turn are influenced by the environmental conditions to which the microorganism is exposed. Bacterial homeostasis and stress response are under the control of the alarmone guanosine tetraphosphate (ppGpp), which intrinsic levels varies across the E. coli species. In the present study, 50 STEC isolates from healthy sheep were evaluated regarding their ppGpp content, cytotoxicity and other relevant genetic and phenotypic characteristics. We found that the level of ppGpp and cytotoxicity varied considerably among the examined strains. Isolates that harboured the stx2 gene were the least cytotoxic and presented the highest levels of ppGpp. All stx2 isolates belonged to phylogroup A, while strains that carried stx1 or both stx1 and stx2 genes pertained to phylogroup B1. All but two stx2 isolates belonged to the stx2b subtype. Strains that belonged to phylogroup B1 displayed on average low levels of ppGpp and high cytotoxicity. Overall, there was a negative correlation between cytotoxicity and ppGpp.

Background
Traumatic events are common globally; however, comprehensive population-based cross-national data on the epidemiology of posttraumatic stress disorder (PTSD), the paradigmatic trauma-related mental disorder, are lacking.
MethodsData were analyzed from 26 population surveys in the World Health Organization World Mental Health Surveys. A total of 71 083 respondents ages 18+ participated. The Composite International Diagnostic Interview assessed exposure to traumatic events as well as 30-day, 12-month, and lifetime PTSD. Respondents were also assessed for treatment in the 12 months preceding the survey. Age of onset distributions were examined by country income level. Associations of PTSD were examined with country income, world region, and respondent demographics.
ResultsThe cross-national lifetime prevalence of PTSD was 3.9% in the total sample and 5.6% among the trauma exposed. Half of respondents with PTSD reported persistent symptoms. Treatment seeking in high-income countries (53.5%) was roughly double that in low-lower middle income (22.8%) and upper-middle income (28.7%) countries. Social disadvantage, including younger age, female sex, being unmarried, being less educated, having lower household income, and being unemployed, was associated with increased risk of lifetime PTSD among the trauma exposed.
ConclusionsPTSD is prevalent cross-nationally, with half of all global cases being persistent. Only half of those with severe PTSD report receiving any treatment and only a minority receive specialty mental health care. Striking disparities in PTSD treatment exist by country income level. Increasing access to effective treatment, especially in low- and middle-income countries, remains critical for reducing the population burden of PTSD.

Background
Although specific phobia is highly prevalent, associated with impairment, and an important risk factor for the development of other mental disorders, cross-national epidemiological data are scarce, especially from low- and middle-income countries. This paper presents epidemiological data from 22 low-, lower-middle-, upper-middle- and high-income countries.
MethodData came from 25 representative population-based surveys conducted in 22 countries (2001–2011) as part of the World Health Organization World Mental Health Surveys initiative (n = 124 902). The presence of specific phobia as defined by the Diagnostic and Statistical Manual of Mental Disorders, fourth edition was evaluated using the World Health Organization Composite International Diagnostic Interview.
ResultsThe cross-national lifetime and 12-month prevalence rates of specific phobia were, respectively, 7.4% and 5.5%, being higher in females (9.8 and 7.7%) than in males (4.9% and 3.3%) and higher in high- and higher-middle-income countries than in low-/lower-middle-income countries. The median age of onset was young (8 years). Of the 12-month patients, 18.7% reported severe role impairment (13.3–21.9% across income groups) and 23.1% reported any treatment (9.6–30.1% across income groups). Lifetime co-morbidity was observed in 60.5% of those with lifetime specific phobia, with the onset of specific phobia preceding the other disorder in most cases (72.6%). Interestingly, rates of impairment, treatment use and co-morbidity increased with the number of fear subtypes.
ConclusionsSpecific phobia is common and associated with impairment in a considerable percentage of cases. Importantly, specific phobia often precedes the onset of other mental disorders, making it a possible early-life indicator of psychopathology vulnerability.

Background
Considerable research has documented that exposure to traumatic events has negative effects on physical and mental health. Much less research has examined the predictors of traumatic event exposure. Increased understanding of risk factors for exposure to traumatic events could be of considerable value in targeting preventive interventions and anticipating service needs.
MethodGeneral population surveys in 24 countries with a combined sample of 68 894 adult respondents across six continents assessed exposure to 29 traumatic event types. Differences in prevalence were examined with cross-tabulations. Exploratory factor analysis was conducted to determine whether traumatic event types clustered into interpretable factors. Survival analysis was carried out to examine associations of sociodemographic characteristics and prior traumatic events with subsequent exposure.
ResultsOver 70% of respondents reported a traumatic event; 30.5% were exposed to four or more. Five types – witnessing death or serious injury, the unexpected death of a loved one, being mugged, being in a life-threatening automobile accident, and experiencing a life-threatening illness or injury – accounted for over half of all exposures. Exposure varied by country, sociodemographics and history of prior traumatic events. Being married was the most consistent protective factor. Exposure to interpersonal violence had the strongest associations with subsequent traumatic events.
ConclusionsGiven the near ubiquity of exposure, limited resources may best be dedicated to those that are more likely to be further exposed such as victims of interpersonal violence. Identifying mechanisms that account for the associations of prior interpersonal violence with subsequent trauma is critical to develop interventions to prevent revictimization.

Background.
To examine cross-national patterns and correlates of lifetime and 12-month comorbid DSM-IV anxiety disorders among people with lifetime and 12-month DSM-IV major depressive disorder (MDD).
Method.Nationally or regionally representative epidemiological interviews were administered to 74 045 adults in 27 surveys across 24 countries in the WHO World Mental Health (WMH) Surveys. DSM-IV MDD, a wide range of comorbid DSM-IV anxiety disorders, and a number of correlates were assessed with the WHO Composite International Diagnostic Interview (CIDI).
Results.45.7% of respondents with lifetime MDD (32.0–46.5% inter-quartile range (IQR) across surveys) had one of more lifetime anxiety disorders. A slightly higher proportion of respondents with 12-month MDD had lifetime anxiety disorders (51.7%, 37.8–54.0% IQR) and only slightly lower proportions of respondents with 12-month MDD had 12-month anxiety disorders (41.6%, 29.9–47.2% IQR). Two-thirds (68%) of respondents with lifetime comorbid anxiety disorders and MDD reported an earlier age-of-onset (AOO) of their first anxiety disorder than their MDD, while 13.5% reported an earlier AOO of MDD and the remaining 18.5% reported the same AOO of both disorders. Women and previously married people had consistently elevated rates of lifetime and 12-month MDD as well as comorbid anxiety disorders. Consistently higher proportions of respondents with 12-month anxious than non-anxious MDD reported severe role impairment (64.4 v. 46.0%; χ21 = 187.0, p < 0.001) and suicide ideation (19.5 v. 8.9%; χ21 = 71.6, p < 0.001). Significantly more respondents with 12-month anxious than non-anxious MDD received treatment for their depression in the 12 months before interview, but this difference was more pronounced in high-income countries (68.8 v. 45.4%; χ21 = 108.8, p < 0.001) than low/middle-income countries (30.3 v. 20.6%; χ21 = 11.7, p < 0.001).
Conclusions.Patterns and correlates of comorbid DSM-IV anxiety disorders among people with DSM-IV MDD are similar across WMH countries. The narrow IQR of the proportion of respondents with temporally prior AOO of anxiety disorders than comorbid MDD (69.6–74.7%) is especially noteworthy. However, the fact that these proportions are not higher among respondents with 12-month than lifetime comorbidity means that temporal priority between lifetime anxiety disorders and MDD is not related to MDD persistence among people with anxious MDD. This, in turn, raises complex questions about the relative importance of temporally primary anxiety disorders as risk markers v. causal risk factors for subsequent MDD onset and persistence, including the possibility that anxiety disorders might primarily be risk markers for MDD onset and causal risk factors for MDD persistence.

Background:
Septoplasty is one of the most common otolaryngological operations. It is often dismissed as a simple procedure, despite the wide range of potential complications. We describe the first reported case of unilateral hemiplegia as a complication of septoplasty.
Methods and results:A 51-year-old man presented with right hemiplegia following a septoplasty and turbinoplasty procedure carried out elsewhere. Cranial imaging showed a breakthrough fracture of the left sphenoid sinus anterior wall and clivus, with a haemorrhagic area in the left paramedian pons, which was responsible for the patient's right hemiplegia. Despite neurological and physiotherapeutic rehabilitation, the patient gained only partial recovery from his right hemiplegia.
Conclusion:Good intra-operative visualisation and appropriate surgical technique are essential to prevent complications and achieve a functional nasal airway. The importance of the presented case to the pre-operative informed consent process is underlined.

Boron carbonitride nanotubes (BCNNTs) were grown with high yield by arc discharge without catalyst particles or pre-grown template nanostructures. Two types of nanotubes (NTs) were formed: thin NTs with diameters of 10–15 nm and thick NTs with diameters of 25–50 nm, all multiwall. Transmission electron microscopy, electron energy loss spectroscopy, and Raman spectroscopy analyses indicate that the thin NTs are carbon NTs (CNTs) while the thick NTs are BCNNTs wrapped around CNTs. The growth kinetic appears to be faster for CNTs than for BCNNTs. Through the concerted substitution of B and N for C in the in situ grown CNTs, template growth of BCNNTs follows the CNTs growth without causing topological changes.

Earlier analysis of the Italian population showed patterns of genetic differentiation that were interpreted as being the result of population settlements going back to pre-Roman times. DNA disease mutations may be a powerful tool in further testing this hypothesis since the analysis of diseased individuals can detect variants too rare to be resolved in normal individuals. We present data on the relative frequencies of 60 cystic fibrosis (CF) mutations in Italy and the geographical distribution of the 12 most frequent CF mutations screened in 3492 CF chromosomes originating in 13 Italian regions. The 12 most frequent mutations characterize about 73% of the Italian CF chromosomes. The most common mutation, ΔF508, has an average frequency of 51%, followed by N1303K and G542X, both with average frequencies around 5%. Multivariate analyses show that the relative frequencies of CF mutations are heterogeneous among Italian regions, and that this heterogeneity is weakly correlated with the geographical pattern of non-DNA ‘classical’ genetic markers. The northern regions are well differentiated from the central-southern regions and within the former group the western and eastern regions are remarkably distinct. Moreover, Sardinia shows the presence of mutation T338I, which seems absent in any other European CF chromosome. The north-western regions of Italy, characterized by the mutation 1717-1G→A, were under Celtic influence, while the north-east regions, characterized by the mutations R1162X, 2183AA→G and 7115G→A, were under the influence of the Venetic culture.
