Cardiovascular diseases, anxiety, and depression are among the most frequent clinical conditions in the Western world, often in comorbidity. Evidence regarding a shared pathophysiology suggests a mediating role by chronic systemic inflammation. The aims of this study were to measure the association between anxiety and depressive symptoms, cardiovascular risk factors, and inflammatory markers. Outpatients aged 40 years or more undergoing colonoscopy after positive fecal occult blood test were enrolled; the following data were collected: body mass index, blood pressure, blood glucose, lipid profile, C-reactive protein (CRP) level, carotid thickness, Hospital Anxiety and Depression Scale, Temperament and Character Inventory, INTERdisciplinary MEDicine Self-Assessment, and 36-Item Short-Form Health Survey scores. Fifty-four patients were enrolled; 30.2% had anxiety symptoms, 18.9% depressive symptoms, and 9.4% concomitant anxiety-depressive symptoms. Anxiety symptoms were associated with low high-density lipoprotein levels. Depressive symptoms were associated with CRP levels, providing supporting evidence for the role of inflammation in the pathophysiology of depression.

Patients and methods: After having modified two items, we administered the Italian version of PDI to all patients hospitalized in a public psychiatric ward (Service of Psychiatric Diagnosis and Treatment of a northern Italian town), who provided their consent and completed it at discharge, from October 21, 2015 to May 31, 2016. We excluded minors and patients with moderate/severe dementia, with poor knowledge of Italian language, who completed PDI in previous hospitalizations and/or were hospitalized for 1 (Kaiser’s criterion), which explained>80% of total variance with good internal consistency: 1) “Loss of self-identity and social role”, 2)“Anxiety and uncertainty for future” and 3) “Loss of personal autonomy”. The PDI and the three-factor scores were statistically significantly positively correlated with the Hamilton Scales for Depression and Anxiety but not with other scale scores. Conclusion: Our preliminary research suggests that PDI can be a reliable tool to assess patients’ dignity perception in a psychiatric setting, until now little investigated, helping professionals to improve quality of care and patients to accept treatments.

Psychiatric Intensive Treatment Facilities (PITF) are health inpatient settings for patients affected by sub-acute psychiatric disorders with impaired personal and social functioning. The aim of this study is to analyse the demographic and clinical variables related to long-stays in an Italian PITF in order to highlight the risk factors for stay lengthening. We retrospectively collected the selected variables from all patients and their stays in a PITF from 1 to 11-2016 to 31-10-2017. We divided the stays according to the median of duration, ≤29 and > 29 days, to compare selected variables in the two groups of stay length. Patients hospitalized for >29 days more frequently presented “Self-neglect”, nursing diagnosis NANDA-I, and needed economic social service support. Multiple linear regression revealed that the presence of some variables as “many medical consultations”, “economic social service support”, “clinical interviews extended to institutional figures” were statistically significantly associated with an increased stay duration, suggesting that both clinical severity and difficult economic conditions were associated with the lengthening of stay. The knowledge of these factors can contribute to improve psychiatric treatments, reducing potential risk conditions for patient institutional dependence.

N-acetylcysteine (NAC) is widely known for its role as a mucolytic and as an antidote to paracetamol overdose. There is increasing interest in the use of NAC in the treatment of several psychiatric disorders. The rationale for the administration of NAC in psychiatric conditions is based on its role as a precursor to the antioxidant glutathione, and its action as a modulating agent of glutamatergic, dopaminergic, neurotropic and inflammatory pathways. Areas covered: This study reviews the available data regarding the use of NAC in different psychiatric disorders including substance use disorders, autism, obsessive-compulsive spectrum disorders, schizophrenia, depression, bipolar disorder. Promising results were found in trials testing the use of NAC, mainly as an add-on treatment, in cannabis use disorder in young people, depression in bipolar disorder, negative symptoms in schizophrenia, and excoriation (skin-picking) disorder. Despite initial optimism, recent findings regarding NAC efficacy in autism have been disappointing. Expert opinion: These preliminary positive results require further confirmation in larger samples and with longer follow-ups. Given its high tolerability and wide availability, NAC represents an important target to investigate in the field of new adjunctive treatments for psychiatric conditions.

IntroductionGrowing evidence has been collected over the complex, intertwined pathophysiological connection among subclinical cardiovascular (CV) disease, i.e. atherosclerosis, systemic low pro-inflammatory states and psychiatric disorders/symptomatology (anxiety, depression), with controversial results.AimAim of this study was to investigate the possible link between subclinical CV risk factors (atherosclerosis), depressive symptoms, and inflammation.MethodsCross-sectional study. Inclusion criteria: outpatients aged ≥40 years, attending colonoscopy after positive faecal occult blood test, negative medical history for cancer. Collected data: blood pressure, glycaemia, lipid profile, waist circumference, BMI, PCR (C reactive protein), LPS (bacterial lipopolysaccharide), ultrasound carotid intima-media thickness (c-IMT). Psychometric tests: HADS, TCI, IMSA, SF36. Statistical analysis performed with STATA13.ResultsThe 54 patients enrolled were equally distributed by gender. CV risk factors were common in the study population, with 33 patients (61.11%) with hypertension, 14 (25.93%) with hyperglycaemia, 20 (37.4%) with hypertriglyceridemia, 19 (35.19%) with low HDL and 64.81% with overweight. High levels of PCR were found in 24 subjects (44.44%). Right c-IMT was increased in 26.41% of the sample, and 11.32% had an atheromatous plaque. Left c-IMT was increased in 24.53% of patients, with a plaque in 7.55% of them. Clinically relevant depressive symptoms were found in the 18.87% of the sample and were statistically significantly associated with PCR (OR = 28.63; P = 0.01).ConclusionsEvidence contributing to the so-called “inflammation theory” of depression and supporting the association between mood and CV disorders was here collected, supporting the need for a multidisciplinary approach to the diagnosis and treatment of such conditions, assuming a clinically-translated PNEI (psycho-neuro-endocrino-immunological) perspective.Disclosure of interestThe authors have not supplied their declaration of competing interest.

IntroductionInflammatory state of the large bowel is a key factor for the development of colorectal cancer (CRC). It has multifactorial aetiology, including psychological determinants. Physical activity may have a protective function against CRC via anti-inflammatory properties; on the contrary, personality traits correlate with an unhealthy and dangerous lifestyle.ObjectiveTo measure the association between personality traits, lifestyle and colonoscopy outcome.MethodsCross sectional study. Patients undergoing colonoscopy aged 40 or more, with a negative history for cancer or inflammatory bowel disease, were enrolled. Data collected: colonoscopy outcome, smoke, alcohol, physical activity, presence/absence of Metabolic Syndrome, personality traits assessed by the Temperament & Character Inventory (TCI).ResultsIn a sample of 53 subjects (females = 24, 45.3%), the mean age was 60.66 ± 9.08. At least one adenoma was found to 23 patients (43.3%). Twenty patients were smokers (37.74%), 36 (67.92%) drank alcohol at least weekly; approximately 60% reported regular physical activity. At the multivariate regression, the outcome was associated to: TCI Self Transcendence domain (ST) (OR = 1.36, P = 0.04) and physical activity (OR = 0.14, P = 0.03).ConclusionPeople with ST's characteristic personality traits and sedentary life style are more likely to have precancerous colorectal lesions. This confirms the protective role of physical activity, and suggests to further explore the role of personality in cancerogenesis.Disclosure of interestThe authors have not supplied their declaration of competing interest.

IntroductionMetabolic syndrome (MetS) is defined by metabolic and cardio-vascular impairments and is frequently associated with anxiety and depressive disorders. Both MetS and anxiety-depressive syndromes feature similar systemic inflammatory alterations. Inflammation of the large bowel is also a key factor for the development of colorectal cancer (CRC).ObjectiveTo measure the prevalence of MetS and symptoms of anxiety and depression among patients undergoing colonoscopy.MethodsCross-sectional study. Patients undergoing colonoscopy aged 40 or more, with negative history for neoplasia or inflammatory bowel disease, were enrolled. Data collected: colonoscopy outcome, presence/absence of MetS (IDF and ATP III criteria), presence/absence of depressive and anxiety symptoms assessed with HADS.ResultsThe sample was made up of 53 patients (female 24, 45.3%). Mean age was 60.66 ± 9.08. At least one adenoma was found to 23 patients (43.3%). Prevalence of MetS ranged from 34% to 36% (ATP III and IDF criteria, respectively). Prevalence of depressive and anxiety symptoms was 20% and 33%, respectively.ConclusionPrevalence of MetS, anxiety and depressive symptoms among patients undergoing colonoscopy was higher than in the general population.Disclosure of interestThe authors have not supplied their declaration of competing interest.

IntroductionAnxiety disorders and Cardiovascular (CV) diseases, among the most common disorders in Western World, are often comorbid. A chronic systemic inflammatory state might be a shared underlining pathophysiological mechanism.AimsTo investigate the association between anxiety symptoms, CV risks factors and inflammatory markers in an outpatient sample.MethodsCross-sectional study. Inclusion criteria: outpatients aged ≥40 years, attending colonoscopy after positive faecal occult blood test, negative medical history for cancer. Collected data: blood pressure, glycaemia, lipid profile, waist circumference, BMI, PCR (C Reactive Protein), LPS (bacterial Lipopolysaccharide). Psychometric tests: HADS, TCI, IMSA, SF36. Statistical analysis performed with STATA13.ResultsFifty four patients enrolled (27 males, 27 females). Sixteen patients (30.19%) were positive for anxiety symptoms. Thirty-three patients (61.11%) had hypertension, 14 (25.93%) hyperglycaemia and 64.81% were overweight, with frank obesity (BMI≥ 30) in 11 subjects (20.37%). Anxiety symptoms were associated with low hematic HDL values (OR = 0.01; P = 0.01) and high concentration of triglycerides (OR = 0.023; P = 0.02) at the multiple regression model. At the univariate logistic analysis, anxiety was associated with LPS (OR = 1.06; P = 0.04).ConclusionsFurther evidence over the epidemiological link between common mental disorders and CV diseases was collected, with possible hints on pathophysiology and causative mechanisms related to inflammation. The importance of screening for anxiety and depression in medical populations is confirmed. Suggestions on future availability of screening tools based on inflammatory-related indicators should be the focus of future research.Disclosure of interestThe authors have not supplied their declaration of competing interest.

IntroductionSeveral studies have shown an association between the Short-Form 36 (SF36) scores and anxiety-depressive symptoms, suggesting that depression in particular could reduce Quality of Life (QoL) to the same, and even greater, extent than chronic non-communicable diseases, such as diabetes and hypertension.AimsTo explore the relationship among QoL and anxiety, depressive and anxiety-depressive symptoms in an outpatient sample.MethodsCross-sectional study. Inclusion criteria: outpatients aged ≥40 years, without history for cancer, attending colonoscopy after positive faecal occult blood test. Collected data: blood pressure, blood glucose, lipid profile. Psychometric test: Hospital Anxiety and Depression Scale (HADS). QoL was assessed with SF36. Statistics performed with STATA13.Results54 patients enrolled (27 females). Sixteen patients (30.2%) were positive for anxiety symptoms, ten (18.9%) for depressive symptoms and five (9.4%) for anxiety-depressive symptoms. The perceived QoL was precarious in twelve subjects (22.2%): eight (15.9%) had low score (≤ 42) at “Mental Component Summary” (MCS) subscale, three (5.7%) at the “Mental Health” item and one patient (1.9%) at the “Vitality” one. At the multiple regression analysis, depressive (OR = 28.63; P = 0.01) and anxiety-depressive symptoms (OR = 11.16; P = 0.02) were associated with MCS.ConclusionsThe association emerging from the present study between depressive/anxiety symptoms and the MCS component of SF36 is consistent with available literature. Study design and small sample size do not allow to generalize results, that need further studies to be confirmed.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Introduction Eating Disorders (ED), including obesity, with and without Metabolic Syndrome (MetS), are associated with anxiety and depression. Increased levels of cytokines and their consequences on the pathway of kynurenine (KYN), the main metabolite of tryptophan, have been proposed to account for these associations. Aim To review the evidences suggesting biochemical connections between the Depression and Anxiety Spectrum (DAS), MetS and ED, respectively, focusing on the role of the KYN pathway. Methods Three PubMed searches of the literature conducted in October 2013 (key words:‘kynurenine’ ‘eating disorders’; ‘kynurenine’ ‘waist circumference’; ‘kynurenine’‘obesity’‘metabolic syndrome’) provided 2, 3 and 7 references, respectively. Results The metabolism of L-tryptophan through the KYN pathway depends on the following three factors: 1) NUTRITION; in underweight ED LKYN metabolites (quinolinic acid, kynurenic acid, 5-hydroxyindoleacetic acid) are significantly reduced until the restoration of normal body weight. In overweight and obesity with and without MetS, increased KYN levels and KYN/tryptophan ratio are found, with abdominal fat content as strongest factor for an increase of the KYN/TRP ratio. 2) AGE; KYN/TRP ratios are markedly increased vs. decreased in overweight and obese adults vs. juveniles, respectively. 3) INFLAMMATION; IFN-gamma induces the indoleamine 2,3- dioxygenase (IDO)-catalyzed synthesis of KYN, whose derivatives increase in diabetes (xanturenic acid), psychosis (kynurenic acid), and depression (quinolinic acid). Conclusions The KYN pathway may link DAS, MetS and ED explaining the frequent association of DAS to so many different disorders. Further studies are needed in order to understand these complex connections.
