Background
Tobacco is a highly prevalent substance of abuse in patients with psychosis. Previous studies have reported an association between tobacco use and schizophrenia. The aim of this study was to analyze the relationship between tobacco use and first-episode psychosis (FEP), age at onset of psychosis, and specific diagnosis of psychosis.
MethodsThe sample consisted of 1105 FEP patients and 1355 controls from the European Network of National Schizophrenia Networks Studying Gene–Environment Interactions (EU-GEI) study. We assessed substance use with the Tobacco and Alcohol Questionnaire and performed a series of regression analyses using case-control status, age of onset of psychosis, and diagnosis as outcomes and tobacco use and frequency of tobacco use as predictors. Analyses were adjusted for sociodemographic characteristics, alcohol, and cannabis use.
ResultsAfter controlling for cannabis use, FEP patients were 2.6 times more likely to use tobacco [p ⩽ 0.001; adjusted odds ratio (AOR) 2.6; 95% confidence interval (CI) [2.1–3.2]] and 1.7 times more likely to smoke 20 or more cigarettes a day (p = 0.003; AOR 1.7; 95% CI [1.2–2.4]) than controls. Tobacco use was associated with an earlier age at psychosis onset (β = −2.3; p ⩽ 0.001; 95% CI [−3.7 to −0.9]) and was 1.3 times more frequent in FEP patients with a diagnosis of schizophrenia than in other diagnoses of psychosis (AOR 1.3; 95% CI [1.0–1.8]); however, these results were no longer significant after controlling for cannabis use.
ConclusionsTobacco and heavy-tobacco use are associated with increased odds of FEP. These findings further support the relevance of tobacco prevention in young populations.

Introduction
INTRODUCTION Facebook is the world’s leading social network with 2,449 million users. Around 22 million of those users are registered in Spain, and 30% of them are aged between 16 and 31. Pro-Ana and Pro-Mia pages have found a space to promote Eating Disorders (ED) as a ‘lifestyle’ using their own code.
ObjectivesOBJECTIVE To study the characteristics of Pro-Ana and Pro-Mia Facebook profiles in Spanish.
MethodsMETHODS A non-computerized research of Facebook pages related to ED advocacy was conducted. The opened time, publications, photos, type of profiles (public/private) and link to a WhatsApp group of 58 Facebook pages were analyzed. A qualitative and descriptive analysis was carried out.
ResultsRESULTS From Facebook profiles: 62.07% contained ‘Ana’ in their profile name; 18.97% had been opened for more than 3 years; 79.31% had been shared; 48.28% mentioned Whatsapp groups; 91.38% were public profiles; 50% named other social networks; 75.86% added text to their publications; 25.86% had shared more than 20 photos on their profiles.
ConclusionsCONCLUSIONS On platforms like Facebook, people with ED can: advocate for their disease, set up networks, share tips/tricks and encourage other users to become part of their community. Technological developments have made it easier to access to this type of resources. Despite the platform’s policy, there are still these kind of profiles that make a case for ED.

Introduction
Eating Disorders are a frequent pathology, particularly among teenagers, a group characterized by its vulnerability and body dissatisfaction. Social networks (SN) can be a gateway to ED, mainly with Pro-Ana and Pro-Mia resources. Despite the aforementioned, SN can also be helpful for professionals, either as a tool of approach to vulnerable groups or as a way of interaction in patients already diagnosed.
ObjectivesTo study the relationship between ED and SN, using the open access evidence available in Pubmed over the last 5 years.
MethodsA single-phase computerised search was carried out in Pubmed. The search terms were: (“Anorexia Nervosa”[Mesh] OR “Bulimia Nervosa”[Mesh] OR “Feeding and Eating Disorders”[Mesh] OR “Eating Disorders”[Tiab] OR “Eating Disorder”[Tiab] OR “Disorder, Eating”[Tiab] OR “Disorders, Eating”[Tiab] OR “Anorexia”[Tiab] OR “Bulimia”[Tiab]) AND (“blogging”[Mesh] OR “social media”[Mesh]). The filters applied were: “free Full Text” and publications for the last 5 years.
Results36.84% studied SN as a positive tool for ED. 47.37% revealed negative influence, only 44.44% focused on Pro-Ana and Pro-Mia. 15.79% provided both positive and negative arguments. The most studied SN were Twitter and Facebook.
ConclusionsDespite the known negative effect that SN can have on ED, they can also be used as a supportive recovery framework. They can be used to identify dangerous behaviours and intervene or as a prevention tool.

Introduction
Eating Disorders (ED) have increased both in number of cases and diagnoses in recent years, partly due to the ease of searching on the Internet. This “community” as they call themselves has a proper language, which makes them easier to connect.
ObjectivesTo know the search frequency of Pro-Ana and Pro-Mia terms in Spanish in the Google search engine.
MethodsA manual screening was carried out based on the word analysis of Pro-Ana and Pro-Mia blogs to obtain their search frequency in Spanish. Using the Google Trends tool, a total of 19 word combinations related to ED and their advocacy were reviewed in the time period from 01/01/2019 to 01/12/20. Some of them such as: “carrera de kilos” (kilos race), “princesa de cristal” (glass princess), “princesa de porcelana” (porcelain princess) and “dieta ABC” (ABC diet) among other terms.
ResultsFrom 2019 to 2020 there has been an increase in the searches related to Eating Disorders (41.63%), ABC diet (9.72%), porcelain princess (25.52%) and kilos race (38.53%). There has also been a decrease in the search for thinspo ana (30.9%), tips ana (4.15%), blog mia (13.09%) or blog ana (0.79%).
ConclusionsSearch trends change over time as they meet the evolving needs. In several media we can find a clear increase in ED during this 2020 due to the confinement related to COVID-19. This is something that we can also relate to this increase in searches for some terms.

Introduction
Nowadays Social Networks (SN) are used not only in a playful way but also as a ‘health’ means of communication. The Pro-Ana and Pro-Mia accounts or profiles -whereby Eating Disorders are advocated as a ‘lifestyle’- increased by 300% over the last decade.
ObjectivesTo analyze Instagram Pro-Ana and Pro-Mia accounts and compare them with Pro-Ana and Pro-Mia Blogs.
MethodsA non-computerized research of Pro-Ana and Pro-Mia Blogs and Instagram profiles was performed. Accepting a risk of Alpha=0.05 and Beta=0.15 in a two-tailed test, 29 subjects were required in each group to detect a difference equal to or greater than 0.2 units. The common standard deviation is assumed to be 0.25. Publication averages, photos, opening years, WhatsApp links and number of followers were analysed and compared. Transversal descriptive study.
ResultsBlogs: 100% had no groups in other SN, 33.33% had been opened for more than 3 years, 30% included personal pictures, 16.67% contained Ana in their title, 53.3% named other Blogs. Instagram: 56.67% included personal pictures, 13.33% mentioned WhatsApp groups, 73.33% had a public profile, 43.33% contained ‘Ana’ in their user name and 53.33% had more than one hundred followers.
ConclusionsThese tools are constantly adapting to the times in which they coexist. There has also been a current increase in Instagram profiles. This study shows a greater linkage to WhatsApp groups on Instagram than on Blogs, together with a higher number of followers, ease of ownership and difficulty of control.

Introduction
INTRODUCTION TikTok is a social network (SN) that allows users to share short videos about different issues. Since the COVID-19 lockdown, there has been an increase in Pro-Ana and Pro-Mia videos in this specific SN.
ObjectivesOBJECTIVES To know the main characteristics about Pro-Ana and Pro-Mia contents among TikTok users.
MethodsMETHODS A search was carried out using uncontrolled language with the term “TCA” (ED in English). The study included only Pro-Ana and Pro-Mia resources in Spanish. Resources under the category “recovery” were excluded. A random sample of 16 TikTok was used, since it is enough to estimate, with a confidence of 95% and an accuracy of +/- 20 percentage units, a population percentage that is expected to be around 20%. The studied variables were images, type of resources, “challenges” and misspelled words.
ResultsRESULTS In the sample, 68.75% of the profiles were created upon confinement, 56.25% had more than 500 followers and 68.75% had more than 3000 “likes”. 43.75% included more than 30% of ED advocacy content, 18.75% promoted challenges and 37.5% used misspelled words to avoid SN censorship.
ConclusionsCONCLUSIONS There has been a remarkable increase in ED-related content as a result of lockdown. In turn, the increasing number of users who are part of TikTok reveals that this is a SN that can be associated with ED advocacy.

Introduction
Schizophrenia is a chronic disease. Several etiopathogenic aetiologies have been posed, among them the existence of cerebral inflammation. S100B is a calcium-binding protein, mainly produced and secreted by astrocytes, that mediates the interaction among glial cells and between glial cells and neurons. Serum S100B levels have been proposed as a peripheral marker of brain inflammation.
ObjectivesThe aim of this research is to study if the serum level of the protein S100B has relationship with positive psychopathology.
Methods31 paranoid schizophrenic inpatients (22 male and 9 female, 36.7±10.3 years) meeting DSM-IV criteria participated in the study. Blood was sampled by venipuncture at 12:00 and 24:00 hours. Blood extractions were carried out during the first 48 hours after hospital admission. Psychopathology was assessed by the Positive and Negative Syndrome Scale (PANSS). Serum S100B levels were measured by sandwich ELISA techniques.
ResultsCorrelations between serum levels of S100B protein and PANSS positive scores are shown in the following table. The first figure corresponds to the Pearson's correlation coefficient, while the figure in brackets corresponds to its statistical significance.
S100B Total Positive Score Delusions Conceptual disorganization Hallucinations Hyperactivity Grandiosity Suspiciousness/ persecution Hostility 12:00 0.354 (0.051) 0.210 (0.249) 0.291 (0.106) 0.412 (0.019) -0.128 (0.486) 0.274 (0.135) 0.010 (0.957) 0.026 (0.887) 24:00 0.462 (0.009) 0.266 (0.141) 0.446 (0.011) 0.345 (0.053) -0.148 (0.419) 0.486 (0.006) 0.064 (0.728) 0.013 (0.942) [panss]
ConclusionsSerum levels of S100B protein may be used as a biological marker of positive psychopathology in paranoid schizophrenia.Acknowledgement

Data from elderly suicides was obtained from two previous studies of community suicides in two localities of Northern Spain, namely, Oviedo between 1983 and 1990, and Gijón between 1975 and 1986. Data from the two localities were obtained by the revision of court register cases. A retrospective study on elderly suicide (over 60 years of age) was carried out. Mean annual specific rates for the elderly in Oviedo for 1982–1991 were 37.7 (58.1 for men and 23.3 for women) and for those in Gijón for the period 1975–1986, 23.4 (40 for men and 11.5 for women). A marked increase was seen in the rates for Gijón from the first (1975–1978) to the last period (1983–1986). This was particularly marked in men. The greatest increase in the rate was seen in men over 75 from Gijón and in those between 1970–1974 from Oviedo. In contrast a decrease was seen in the 65–69 age group rates for both men and women. A tendency for the rates to increase was seen but no important increase for elderly suicides was evident.

Background and aims:
Musical hallucinations are a rare phenomenon in clinical practice. The purpose of this study was to analyze the clinical spectrum of musical hallucinations.
Method:We analysed demographic and clinical features of cases published in English, Italian, French or Spanish between 1991 and 2006 registered in MEDLINE, including three of our own cases. The cases were separated into four groups according to their main diagnoses (hearing impairment; psychiatric disorder; neurological disorder; toxic or metabolic disorder).
Results:115 patients with musical hallucinations were included, of which 63.5% were female. The mean age was 57,25 years. Main diagnoses were: psychiatric disorder (46.1%; schizophrenia 30.4%), neurological disorder (21,7%), hearing impairment (17,4%), toxic or metabolic disorder (12.2%) and 2.6% other diagnoses.
61.7% patients presented simple diagnoses while 36.5% presented two or more diagnoses. 2.1% of patients didn't receive any diagnoses. 35.7% of patients and 60.9% of non psychiatric patients presented hearing impairment.
Both instrumental and vocal were the more frequent musical hallucinations and most of the patients had insight about the abnormality of their perceptions. Another kind of hallucinations was present in 40.9% of patients, auditory hallucinations being the most common. Also, 38,3% of the global sample had abnormalities in brain structural image (MRI, CT).
Conclusions:Musical hallucinations are a heterogeneous phenomenon in clinical practice. published cases describe them as more common in women and in psychiatric and neurological patients. Hearing impairment seem to be an important risk factor in the development of musical hallucinations.

Background
Natural polyamines (putrescine, spermidine and spermine) are low molecular weight highly protonated aliphatic molecules that physiologically modulate NMDA, AMPA/kainate glutamatergic receptors and limbic dopaminergic neurotransmission. Previous studies had demonstrated that polyamine metabolism might be disrupted in schizophrenia, what could potentially be linked to glutamatergic dysfunction. In particular, polyamine levels in blood and fibroblast cultures from patients with schizophrenia had previously been found to be higher than in healthy controls. Indeed, a significant positive correlation between blood polyamine levels and severity of illness may exist.
MethodsIn order to test potential differences in blood polyamine levels between drug-free schizophrenia in-patients (n = 12), and healthy controls (n = 26, blood donors), spermidine (spd), spermine (spm), and spermidine/spermine index (spd/spm) were determined using HPLC after dansylation.
ResultsNo significant differences were found between groups (t = 0,974; df = 36; P = 0,337 for spd, t = l0, 52; df = 36; P = 0,959 for Spm, and, t = 0, 662; df = 36; P = 0,512 for spd/spm).
ConclusionsThough we couldn’t replicate previous findings suggesting disturbances in blood polyamine levels in schizophrenia, this issue may be a promising target. Future research should take into account possible factors such as sex, nutritional state, and stress.

Background and aims:
Auditory and musical hallucinations have been reported in patients as an adverse effect of the use of opioids. Hearing loss, old age, and female gender are considered risk factors in the development of musical hallucinations. The aim of this report is to describe a case of a patient with auditory and musical hallucinations and to discuss the role of an opioid –tramadol- in the origin of those.
Methods:An 80 years old woman experiencing auditory hallucinations was referred to our hospital from an emergency room. The patient had bilateral mild hearing loss and was receiving tramadol 112.5 mg/daily during the last year for cervical pain. In the last ten months, she had been gradually noticing the voice of her dead husband coming from under her pillow, as well as intermittently hearing popular songs being played inside her head. The patient had good insight on both types of abnormal perceptions, which were reported as increasingly unpleasant through time.
Results:Tramadol was discontinued and pimocide (range 1-4 mg/day) and loracepam (2.5 mg/day) were introduced, achieving the improvement of the hallucinations and the anxiety associated with them.
Conclusions:The outcome of this case supports the hypotheses that Opioids could induce musical hallucinations. Hearing impairment, old age, and gender could be underlying risk factors on the development of musical hallucinations.

Objective:
Malondialdehyde (MDA) is a common biologic marker of oxidative stress used in psychiatric research. Data regarding MDA levels in healthy subjects are controversial. One factor affecting MDA levels may stem from the existence of a circadian rhythm of MDA formation. The objective of this study consists of investigating whether MDA formation has a circadian rhythm of formation in healthy human subjects.
Methods:The sample was comprised by 9 healthy male subjects. None of them had a history of medical or neurological disease and routine laboratory parameters were normal. The study was carried out in accordance with the Helsinki Declaration and all subjects gave written informed consent before their inclusion. Blood samples were extracted at 12:00 and 2:00 in December 2004. The same routine was followed during the two experimental sessions. Serum MDA was determined by the thiobarbituric acid reactive substance (TBARS) according to the method of Ohkaba et al (1979).
Results:The sample was comprised by 9 male healthy subjects (age 33.0±11.7). There were significant differences in MDA levels between 12:00 and 2:00 (2.33±1.01 vs. 1.58±0.48, p<0.015).
Conclusions:MDA has a circadian rhythm of formation with higher levels at 12:00 than 2:00. This variation in circadian MDA levels of formation should be accounted when researching in this field.

Introduction
The self-medication hypothesis suggests that patients diagnosed with schizophrenia might smoke as an attempt to self-medicate theirsymptoms. As a consequence, smoking cessation could worsen their clinical status.
ObjectivesTo assess the clinical changes associated with tobacco cessation in a sample of smoking outpatients with schizophrenia.
MethodsSample: 63 smoking outpatients with DSM-IV Schizophrenia from three Mental Health Centers located in Northern Spain [77.0% males; mean age (SD) = 43.90 (8.72); average daily cigarette use (SD) = 27.99 (12.55)]. Instruments: (1) Clinical symptoms: Positive and Negative Symptoms Scale (PANSS), Hamilton Depression Rating Scale (HDRS), Clinical Global Impression (CGI). (2) Pattern of tobacco use: n° cigarettes/day; Expired carbon monoxide (CO ppm). Design: A quasi-experimental design with two groups was implemented: control group (GC − 18 patients not willing to stop smoking), and treatment group [TG − 45 patients in smoking cessation supported by nicotine patches or vareniclina (12 weeks)]. Patients were evaluated at baseline and at week 11 (end of program). Paired sample t-test was used to detect changes in clinical symptoms from baseline to follow-up.
Results23.1% stopped smoking (from TG). No significant differences were found between baseline and follow-up scores (p>.05) among smokers and abstinent in PANSS subscales, HDRS and CGI.
ConclusionsTobacco cessation did not have a significant effect on the clinical symptoms of this group of patients. Further studies should analyze the stability of these outcomes at longer follow-ups to confirm our results.

Introduction:
Relationships between total antioxidant capacity (TAC) and psychopathology in schizophrenia is controversial. Different methodological approaches may be a bias factor.
Objective:The aim of this research is to analyze the relationship between psychopathology as individual items and psychopathology as syndromes with the serum TAC concentration in schizophrenic patients.
Methods:20 DSM-IV paranoid schizophrenic outpatients were recruited from the psychiatric outpatient's clinic of the University Hospital of the Canary Islands. the severity of schizophrenia symptoms was measured with the Positive and Negative Syndrome Scale (PANSS). Blood samples were collected at 12:00 and 00:00 hours. Relationships between quantitative variables were assessed with the Pearson's correlation coefficient.
Results:There was a significant correlation between the PANSS positive subscale and the nocturnal TAC levels (r=0.527, p< 0.02). the PANSS negative subscale was not correlated with TAC concentrations. Item by item scores of the positive and negative PANSS correlations with nocturnal and diurnal TAC levels revealed that only item 6 (suspicion) of the positive PANSS subscale was significantly correlated with the nocturnal TAC concentrations (r=0,491, p< 0.03). Only item 3 (poor contact) of the negative PANSS subscale was also significantly correlated with the nocturnal TAC concentrations (r=0,516, p< 0.02).
Conclusions:We strongly recommend analyzing not only global scores of psychopathology but individual items scores when researching on biological markers in schizophrenia.

Introduction
Few studies focus on peripheral biological markers of personality. Melatonin (MLT), the main hormonal product of the pineal gland, has been used both as a diagnostic and therapeutic element and has been related with chronotype, depression and schizophrenia, among other psychiatric conditions. However, there is a paucity of studies on its use as a personality marker. The present work aims to determine whether serum MLT levels are related with the Eysenck's personality extraversion/introversion (E/I) dimension.
MethodsA sample of 100 healthy volunteers participated in the study. The E/I personality dimension was evaluated using the EPQ-BV (Eysenck Personality Questionnaire – Brief Version). Three blood samples were taken (at 09:00, 12:00 and 00:00 h) to measure MLT. MLT was analysed in serum by an ELISA. Serum MLT concentrations are expressed in pg/ml.
ResultsMLT levels displayed a clearly circadian pattern, with night levels being significantly higher than day-time levels (00:00: 35.78 ± 23.53 vs. 09:00: 7.78 ± 5.56, 12.00: 3.35 ± 1.94, p < 0.05). Serum MLT levels at 09:00 h were significantly higher than MLT levels at 12:00 h (7.78 ± 5.56 vs. 3.35 ± 1.94, p < 0.05). No significant correlations were found between E/I scores and serum MLT levels at 09:00 (r = – 0.06, p = 0.55) 12:00 (r = – 0.12, p = 0.25) and 00:00 h (r = – 0.01, p = 0.99).
ConclusionsThere is no relationship between MLT levels and the E/I personality dimension. Future studies should examine the neuroticism dimension of personality.

The objective of this study was to assess the effectiveness of a catheter-related bloodstream infection (CR BSI) reduction programme and healthcare workers' compliance with recommendations. A 3-year surveillance programme of CR BSIs in all hospital settings was implemented. As part of the programme, there was a direct observation of insertion and maintenance of central venous catheters (CVCs) to determine performance. A total of 38 education courses were held over the study period and feedback reports with the results of surveillance and recommendations were delivered to healthcare workers every 6 months. A total of 6722 short-term CVCs were inserted in 4982 patients for 58 763 catheter-days. Improvements of compliance with hand hygiene was verified at the insertion (87·1–100%, P < 0·001) and maintenance (51·1–72·1%, P = 0·029) of CVCs; and the use of chlorhexidine for skin disinfection was implemented at insertion (35·7–65·4%, P < 0·001) and maintenance (33·3–45·9%, P < 0·197) of CVCs. There were 266 CR BSI incidents recorded with an annual incidence density of 5·75/1000 catheter-days in the first year, 4·38 in the second year [rate ratio (RR) 0·76, 95% confidence interval (CI) 0·57–1·01] and 3·46 in the third year (RR 0·60, 95% CI 0·44–0·81). The education programme clearly improved compliance with recommendations for CVC handling, and was effective in reducing the burden of CR BSIs.

We establish Whitehead and Ganea characterizations for proper LS-category. We use the embedding of the proper category into the exterior category, and construct in the latter a suitable closed model structure of Strøm type. Then, from the axiomatic LS-category arising from the exterior homotopy category we can recover the corresponding proper LS invariants. Some applications are given.

Organic chromophores have been exploited for a wide range of discrete optical and electronic functions as well as a growing number of combined opto-electronic functions. We are pursuing development of organic and polymer materials for a range of applications that require properties including liquid crystallinity, second order optical nonlinearity, photorefractivity and, more recently, special nonlinear optical behavior involving molecular chirality.
