The influence of weather on the course of bipolar disorder: A systematic review

Background and objectives: Several studies have addressed the relationship between bipolar disorder and meteorological variables, but no previous review focusing on the influence of a wide range of meteorological variables on bipolar disorder has been published. The aim of this study is to conduct a systematic review about the influence of weather on the clinical course of bipolar disorder patients.MethodsFollowing PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines, the main electronic medical databases were searched in February 2020, and studies were screened based on the eligibility criteria. 24 studies were selected for qualitative synthesis. Most of them were observational retrospective studies based in medical records.ResultsThe most studied meteorological variables were temperature and sunlight, and the most studied clinical outcomes were hospital admissions. Significant correlations were found between temperature and sunlight and clinical outcomes, although the findings were heterogeneous. Higher temperatures may trigger bipolar disorder relapses that require hospital admission, and higher expositions to sunlight may increase the risk of manic episodes.ConclusionMeteorological variables seem to have an influence in the course of bipolar disorder, especially temperature and sunlight, although further studies are needed to clarify this possible relationship.

General care in the management of severe traumatic brain injury: Latin American consensus. / Cuidados generales en el manejo del traumatismo craneoencefálico grave: consenso latinoamericano.

Severe traumatic brain injury (sTBI) remains prevalent in the young adult population. Indeed, far from descending, the incidence of sTBI remains high. One of the key bases of treatment is to avoid, detect and correct secondary injuries of systemic origin, which aggravate the primary lesion. Much of this can be achieved by maintaining an adequate physiological microenvironment allowing recovery of the damaged brain tissue. General care measures are nonspecific actions designed to meet that objective. The available guidelines on the management of sTBI have not included the topics contemplated in this consensus. In this regard, a group of members of the Latin American Brain Injury Consortium (LABIC), involved in the different aspects of the acute management of sTBI (neurosurgeons, intensivists, anesthesiologists, neurologists, nurses and physiotherapists) were gathered. An exhaustive literature search was made of selected topics in the LILACS, PubMed, Embase, Scopus, Cochrane Controlled Register of Trials and Web of Science databases. To establish recommendations or suggestions with their respective strength or weakness, the GRADE methodology (Grading of Recommendations, Assessment, Development and Evaluation) was applied. Additionally, certain recommendations (included in complementary material) were not assessed by GRADE, because they constitute a set of therapeutic actions of effective compliance, in which it was not possible to apply the said methodology. Thirty-two recommendations were established, 16 strong and 16 weak, with their respective levels of evidence. This consensus attempts to standardize and establish basic general care measures in this particular patient population.

In Situ Synthesis of Al-Based MMCs Reinforced with AlN by Mechanical Alloying under NH3 Gas.

Aluminum matrix composites (AMCs) reinforced by aluminum nitride were prepared by mechanical alloying followed by a simple press and sintering method. Milling began under vacuum and after a period of between 1 and 4 h, NH3 gas flow (1 cm³/s) was incorporated until the total milling time of 5 h was reached. Results show that in addition to the strain hardening taking place during mechanical alloying, NH3 plays an additional role in powder hardening. Thereby, the properties of the sintered compacts are strongly influenced by the amount of N incorporated into the powders during milling and the subsequent formation of AlN during the consolidation process. The obtained AMC reaches tensile strengths as high as 459 MPa and hardness much higher than that of the as-received aluminum compact.

Uncovered secret of a Vasseur-Tramond wax model.

The technique of anatomical wax modelling reached its heyday in Italy during the 18th century, through a fruitful collaboration between sculptors and anatomists. It soon spread to other countries, and prestigious schools were created in England, France, Spain and Austria. Paris subsequently replaced Italy as the major centre of manufacture, and anatomical waxes were created there from the mid-19th century in workshops such as that of Vasseur-Tramond. This workshop began to sell waxes to European Faculties of Medicine and Schools of Surgery around 1880. Little is known of the technique employed in the creation of such artefacts as this was deemed a professional secret. To gain some insight into the methods of construction, we have studied a Vasseur-Tramond wax model in the Valladolid University Anatomy Museum, Spain, by means of multi-slice computerised tomography and X-ray analysis by means of environmental scanning electron microscopy. Scanning electron microscopy was used to examine the hair. These results have revealed some of the methods used to make these anatomical models and the materials employed.

An Exploration of the Reliability and Validity of the Spanish Version of the 'Voice and You' (VAY): A Scale for Measuring the Relationship with Voices.

UNLABELLED: The purpose of this study was to adapt the 'Voice and You' Scale (VAY) (Hayward, Denney, Vaughan, & Fowler, 2008) to Spanish and explore its psychometric properties for measuring the perceived relationship with voices. A sample of 50 psychiatric patients with verbal auditory hallucinations (48 had a psychotic disorder and two a borderline personality disorder) was used. Its reliability was calculated using the Cronbach's α and test-retest, and concurrent validity by the Pearson correlation coefficient of the VAY with the Beliefs About Voices Questionnaire and the Psychotic Symptom Rating Scales. The results showed that internal consistency of the Spanish version of the VAY ranged from 0.74 to 0.84 on the various subscales, and test-retest reliability varied from 0.74 to 0.83 on three subscales (voice 'dominance', 'intrusiveness' and hearer 'dependence'), and was lower (0.68) on the hearer 'distance' subscale. Concurrent validity was acceptable as significant associations were found with the Beliefs About Voices Questionnaire and the Psychotic Symptom Rating Scales subscales. It is concluded that the Spanish version of the VAY is a reliable and valid instrument that can assist the exploration of voices within relational frameworks across research and clinical domains. KEY PRACTITIONER MESSAGE: The Spanish version of the VAY is a reliable, valid instrument for evaluating the perception a person can have about his or her relationship with the voices and how the person relates to them. Voices that are perceived as relating dominantly and intrusively, and from whom distance is sought, seem to be distressing and cause disturbance. Voices that are related to dependently are perceived as having benevolent intent and are engaged with. Benevolent or neutral voices may be considered as intrusive because of the intensity and frequency with which they are experienced.

Risk factors for suicide in schizophrenia: systematic review and clinical recommendations.

OBJECTIVE: To identify risk factors associated with suicide of patients with schizophrenia and provide clinical recommendations, which integrate research findings into a consensus based on clinical experience and evidence. METHOD: A task force formed of experts and clinicians iteratively developed consensus through serial revisions using the Delphi method. Initial survey items were based on systematic literature review published up to June 2013. RESULTS: Various risk factors were reported to be implicated in suicide in schizophrenia. Our findings indicate that suicide risk in schizophrenia is mainly related to affective symptoms, history of a suicide attempt and number of psychiatric admissions. Other risk factors identified are given by younger age, closeness to illness onset, older age at illness onset, male sex, substance abuse and period during or following psychiatric discharge. Integrating the evidence and the experience of the task force members, a consensus was reached on 14 clinical recommendations. CONCLUSION: Identification of risk factors for suicide in individuals diagnosed with schizophrenia is imperative to improve clinical management and develop strategies to reduce the incidence of suicide in this population. This study provides the critical overview of available data and clinical recommendations on recognition and management of the above-mentioned risk factors.

Diagnóstico de infertilidad masculina: necesidad de valoraciones funcionales y cromatínicas / Diagnosis of Male Infertility: A Need of Functional and Chromatin Evaluation

Objetivos: Estudiar la incidencia de alteraciones funcionales y cromatínicas en espermatozoides de pacientes, agrupados según normalidad de los parámetros seminales estándar en función de la quinta edición del manual de la Organización Mundial de la Salud (OMS). Identificar y correlacionar las características alteradas con mayor frecuencia en la subpoblación normal para los parámetros estándar. Materiales y métodos: Estudio prospectivo en el que se evaluaron en muestras de semen de 110 pacientes y 6 donantes fértiles (control), los parámetros seminales estándar (volumen, concentración, motilidad, morfología, células redondas, células peroxidasa-positivas) según las directrices de la OMS, así como test complementarios funcionales (sobrevida 24 horas, test hipo-osmótico, test de estrés modificado) y adicionales (azul de anilina, nitroblue-tetrazolium, TUNEL). Según el resultado de los análisis estándar los pacientes se dividieron en dos grupos (A: todos los parámetros estándar normales; B: al menos uno de los parámetros estándar alterado). Resultados: El 96,61% de las muestras presentó alterada al menos una de las variables analizadas. Los grupos A y B mostraron diferencia estadísticamente significativa en todos los test complementarios. En el grupo A el 93,68% de las muestras presentó al menos un test complementario alterado, y la variable afectada con mayor frecuencia fue la fragmentación del ADN espermático (16,95%). Conclusiones: La profundización en el estudio seminal, introduciendo en la rutina ensayos funcionales y cromatínicos, redunda en un diagnóstico más afinado de la infertilidad del varón. Los parámetros de la OMS deben considerarse como un abordaje primario (AU)

Objectives: To evaluate the incidence of functional and chromatin alterations on spermatozoids in patients grouped according to normality of standard semen parameters based on the 5th edition of the World Health Organization (WHO) guidelines. To identify and correlate the most frequently altered characteristics in the normal standard semen parameters sub-population. Materials and Methods: A prospective study was performed. It evaluated standard semen parameters (volume, sperm concentration, motility and morphology, round cells, peroxidase-positive cells) according to WHO guidelines, as well as functional tests (24hours survival, hypoosmotic swelling test, modified stress test), and additional assays (aniline blue, nitroblue-tetrazolium, TUNEL) in 110 semen samples from patients and 6 from fertile donors (control). Based on standard semen parameters values, patients were divided into two groups (A: all standard parameters normal; B: one altered standard parameter at least). Results: At least one of the variables analyzed was altered in 96.61% of the samples. Groups A and B showed statistically significant differences in all the complementary tests. At least one of the complementary tests were altered in 93.68% of the samples in group A, and the most frequently affected variable was sperm DNA fragmentation (16.95%). Conclusions: Performing a more in-depth seminal study within the routine functional and chromatin assays provides a more precise diagnosis of male infertility. The WHO standards should be considered as a primary approach (AU)

Social cognition and interaction training (SCIT) for outpatients with bipolar disorder.

INTRODUCTION: Patients with bipolar disorder show social cognition deficits during both symptomatic and euthymic phases of the illness, partially independent of other cognitive dysfunctions and current mood. Previous studies in schizophrenia have revealed that social cognition is a modifiable domain. Social cognition and interaction training (SCIT) is an 18-week, manual-based, group treatment designed to improve social functioning by way of social cognition. METHOD: 37 outpatients with DSM-IV-TR bipolar and schizoaffective disorders were randomly assigned to treatment as usual (TAU)+SCIT (n=21) or TAU (n=16). Independent, blind evaluators assessed subjects before and after the intervention on Face Emotion Identification Task (FEIT), Face Emotion Discrimination (FEDT), Emotion Recognition (ER40), Theory of Mind (Hinting Task) and Hostility Bias (AIHQ). RESULTS: Analysis of covariance revealed significant group effects for emotion perception, theory of mind, and depressive symptoms. The SCIT group showed a small within-group decrease on the AIHQ Blame subscale, a moderate decrease in AIHQ Hostility Bias, a small increase in scores on the Hinting Task, a moderate increase on the ER40, and large increases on the FEDT and FEIT. There was no evidence of effects on aggressive attributional biases or on global functioning. LIMITATION: No follow up assessment was conducted, so it is unknown whether the effects of SCIT persist over time. CONCLUSION: This trial provides preliminary evidence that SCIT is feasible and may improve social cognition for bipolar and schizoaffective outpatients.

Occupational disability in bipolar disorder: analysis of predictors of being on severe disablement benefit (PREBIS study data).

OBJECTIVE: Patients diagnosed with bipolar disorder (BD) are reported to have significant work impairment during interepisode intervals. This study was carried out to assess potential predictors of occupational disability in a longitudinal follow-up of euthymic patients. METHOD: We included 327 euthymic patients diagnosed with BD type I or type II, 226 of whom were employed and 101 were receiving a severe disablement benefit (SDB). Sociodemographic data were studied and episode recurrence was assessed along a 1-year follow-up. Logistic regression analysis was applied to determine predictors of receiving SDB. Cox regression was built to study recurrences. RESULTS: Predictors of receiving SDB were: axis II comorbidity [Odds Ratio (OR) = 2.94, CI: 1.26-6.86, P = 0.013], number of manic episodes (OR = 1.21, CI: 1.10-1.34, P < 0.001), being without stable partner (OR = 2.44, CI: 1.34-4.44, P = 0.004) and older age (OR = 1.08, CI: 1.05-1.12, P < 0.001). Bipolar patients receiving SDB presented more episodic recurrences regardless of polarity than employed bipolar patients (P = 0.002). The time until recurrence in 25% of the bipolar patients receiving SDB was 6.08 months (CI: 4.44-11.77) being 13.08 months (CI: 9.60 to -) in the employed group. CONCLUSION: Occupational disability in bipolar patients is associated with axis II comorbidity, more previous manic episodes, not having a stable relationship, older age, and more recurrences at 1-year follow-up.

Síndrome del ligamento arcuato medio: a propósito de tres casos y revisión de la literatura / Median arcuate ligament syndrome: a presentation of three cases and a review of the literature

El síndrome del ligamento arcuato medio (SLAM), o síndrome de compresión del tronco celiaco, es causado por la compresión extrínseca del ligamento arcuato medio, bandas fibrosas prominentes y tejido ganglionar periaórtico. En muchas ocasiones es asintomático, pero puede presentar síntomas como dolor abdominal posprandial o durante el ejercicio náuseas, vómitos y pérdida de peso. Presentamos tres pacientes, uno de ellos asintomático. Los otros dos casos precisaron tratamiento quirúrgico, en uno de ellos mediante liberación laparoscópica y en el otro mediante cirugía abierta. En ambos casos se obtuvo mejoría clínica y seguimiento mediante ecografía doppler-color satisfactorio. El SLAM representa una entidad poco frecuente de dolor abdominal. Las técnicas diagnósticas menos invasivas, como la ecografía doppler-color para el screening y la angio TC preoperatoria, obtienen buenos resultados en comparación con la arteriografía. El tratamiento quirúrgico mediante abordaje laparoscópico, con o sin asociación de tratamiento revascularizador endovascular, constituye una técnica terapéutica segura y eficaz(AU)

Median arcuate ligament syndrome (MALS) or celiac artery compression syndrome is caused by extrinsic compression of the median arcuate ligament, prominent fibrous bands and ganglionic periaortic tissue. It is asymptomatic on many occasions, but can present with symptoms such as, abdominal pain after eating or during exercise, nausea, vomiting, and loss of weight. We present three patients, one of whom was asymptomatic. The other two required surgical treatment, using laparoscopic release in one, and open surgery on the other. A clinical improvement was achieved in both cases and the follow-up by colour Doppler ultrasound was satisfactory. MALS is a rare abdominal pain condition. The less invasive diagnostic techniques, such as colour Doppler ultrasound and pre-operative angio CT, obtain good results compared to angioplasty. Surgical treatment using a laparoscopic approach, whether or not it is associated with endovascular revascularisation treatment, is a safe and effective therapeutic technique(AU)

Introducción:Conocer las opiniones, creencias y preocupaciones de la población general sobre dos enfermedades mentales graves: esquizofrenia y trastorno bipolar. Material y métodos:Se construyó un cuestionario ad-hoc para encuesta. Un panel de siete expertos extrajo los contenidos. También participaron: ASAENES, ABBA, FEAFES-ANDALUCIA, AMAFE, FEMASAM y AFAEM-5. El cuestionario contenía 12 preguntas sobre: conocimiento de las patologías, dificultades diagnósticas, síntomas, desencadenantes, interferencia, tratamientos y efectividad, creencias y preocupaciones. Administrado: IV Campaña de Concienciación Social sobre la Enfermedad Mental Grave (Madrid y Sevilla, septiembre - octubre 2009). Resultados:Se recogieron 5.473 encuestas, 55,8% en Sevilla. El 66,2% de la muestra eran mujeres y la edad media 35 años (DE=14,5). El 82% conocía ambas enfermedades, pero el 51% no conocía ningún síntoma de la esquizofrenia. Otras opiniones destacables: son difíciles de diagnosticar (59%), no se diagnostican por rechazo social (27%), interfieren bastante en la vida cotidiana (49%) o impiden la vida normal (42%), los tratamientos eficaces son psicológicos (82%) y farmacológicos (72%). Las creencias refieren: rechazo social, sobrecarga familiar y sufrimiento del paciente. Las preocupaciones refieren: peligrosidad, rechazo social, falta de información y escasez de recursos. Conclusiones:Existe desconocimiento sobre la sintomatología. La mayoría desconoce síntomas específicos y resalta los negativos. Se atribuye mayor eficacia al tratamiento conjunto psicológico-farmacológico. Preocupan la estigmatización y la sobrecarga familiar y personal(AU)

Introduction:To find out the opinions, beliefs and concerns of the Spanish population on serious mental diseases: schizophrenia and bipolar disorder. Material and methods:An ad-hoc questionnaire was constructed for the survey. A panel of seven experts extracted the contents. The Societies that involved were: ASAENES, ABBA, FEAFES-ANDALUCÍA, AMAFE, and AFAEM-5 advocacy societies were also involved. The questionnaire contained 12 questions about: knowledge of the diseases, diagnostic difficulties, symptoms, triggering factors, interference, treatments and effectiveness, beliefs and concerns. The questionnaire was administered during the IV Campaign of Social Awareness about Serious Mental Illness (Madrid and Seville, September-October 2009). Results:A total of 5,473 questionnaires were collected, 55.8% in Seville. The majority (66.2%) of the sample were women, and the mean age was 35 years (SD=14.5). Both illnesses were known by 82% of the population, but 51% did not known any symptom of schizophrenia. Other notable opinions were; they are difficult to diagnose (59%), they were not diagnosed due to social rejection (27%), interfered quite a lot with daily life (49%) or prevented a normal life (42%), the effective treatments are psychological (72%). Beliefs were: social rejection, family burden, and patient suffering. Concerns included: dangerousness, social rejection, lack of information, and scarcity of resources. Conclusions:There is a lack of knowledge of the symptoms. The majority do not know about specific symptoms and highlight the negative ones. Combined pharmacological-psychological treatment is believed to be most effective. Social stigma and family and personal burden are concerns(AU)

DNA sperm damage correlates with nuclear ultrastructural sperm defects in teratozoospermic men.

Sperm morphology has consistently been the best indicator of male fertility. Transmission electron microscopy currently provides the most information on the subcellular details of sperm structure. Recently, assessment of sperm DNA damage has been employed to assess fertility potential. The purpose of this work was to link sperm DNA damage, evaluated by an intercalated fluorescent dye, with the structural characteristics of sperm. Conventional semen analysis was performed on samples from men undergoing fertility evaluation. Thirty men were evaluated and assigned to three subgroups based on strict criteria for sperm morphology: normal morphology (>14% normal forms), intermediate morphology (5-14% normal forms), and poor morphology (<5% normal forms). By quantifying acridine orange-positive cells and ultrastructural sperm defects, we found that the poor morphology pattern group showed a positive association between sperm carrying damaged DNA and the percentage of sperm nucleus with vacuoles (P = 0.01). No statistically significant correlations were established in other ultrastructural characteristics of sperm, including immature chromatin, lytic changes, or abnormal sperm tails. These results suggest that zones without chromatin in the sperm nucleus reflect underlying chromosomal or DNA defects in severe teratozoospermic men. This association should be considered in the evaluation of male fertility.

PillCamColon Capsule for the study of colonic pathology in clinical practice. Study of agreement with colonoscopy.

INTRODUCTION: several studies have pointed out the effectiveness of the PillCam colon capsule endoscopy (CCE) compared with the colonoscopy in the study of the colonic pathology. AIMS AND METHODS: the objective of our study was to assess the agreement in the diagnosis of CCE with conventional colonoscopy as well as its sensitivity and specificity, and to describe the findings of the CCE in our clinical practice. Consecutive patients with abdominal symptoms were included in the study. The CCE was performed as previously reported (with PEG and sodium phosphate as laxative agents). The nature and location of the findings, colonic transit time, complications, cleanliness degree and consistency with diagnostic colonoscopy, when performed, were analyzed. RESULTS: a total of 144 subjects (67 women and 77 men); (52.17 ± 16.71 years) with the following indications were included: screening of Colorectal cancer (88 patients), control after polipectomy (24), incomplete colonoscopy (7), rectal bleeding (10), anemia (8), diarrhea (7). The CCE exploration was complete in 134/144 cases (93%), with no case of retention. The preparation was good-very good in 88/134 (65,6%), fair in 26/134 (19,4%) and poor in 20/134 (15%) of the cases. The average colonic transit was of 140.76 min (9-603). Any adverse effect was notified.In 44 cases a colonoscopy was carried out after CCE (results were hidden from another endoscopist). Compared to colonoscopy, the rate of agreement was 75,6%, the sensitivity was 84% and the specificity 62,5%, PPV was 77,7% and NPV was 71,4%.The colonic findings in 134 CCE were: in 34 cases CCE it did not show lesions, diverticulosis in 63 explorations, polyps in 43, angiodysplasias in 15, Crohn's Disease in 9 and ulcerative colitis in other 8 cases. CONCLUSIONS: the CCE is an effective and reliable technique for the detection of lesions in colon, and because of its high agreement with the colonoscopy, it could be useful in clinical practice. Further studies with large seria and cost-effectiveness analysis are needed to confirm these data.

Individualizing antipsychotic treatment selection in schizophrenia: characteristics of empirically derived patient subgroups.

Treatment of schizophrenia with antipsychotic drugs is frequently sub-optimal. One reason for this may be heterogeneity between patients with schizophrenia. The objectives of this study were to identify patient, disease and treatment attributes that are important for physicians in choosing an antipsychotic drug, and to identify empirically subgroups of patients who may respond differentially to antipsychotic drugs. The survey was conducted by structured interview of 744 randomly-selected psychiatrists in four European countries who recruited 3996 patients with schizophrenia. Information on 39 variables was collected. Multiple component analysis was used to identify dimensions that explained the variance between patients. Three axes, accounting for 99% of the variance, were associated with disease severity (64%), socioeconomic status (27%) and patient autonomy (8%). These dimensions discriminated between six discrete patient subgroups, identified using ascending hierarchical classification analysis. The six subgroups differed regarding educational level, illness severity, autonomy, symptom presentation, addictive behaviors, comorbidities and cardiometabolic risk factors. Subgroup 1 patients had moderately severe physician-rated disease and addictive behaviours (23.2%); Subgroup 2 patients were well-integrated and autonomous with mild to moderate disease (6.7%); Subgroup 3 patients were less well-integrated with mild to moderate disease, living alone (11.2%); Subgroup 4 patients were women with low education levels (5.4%), Subgroup 5 patients were young men with severe disease (36.8%); and Subgroup 6 patients were poorly-integrated with moderately severe disease, needing caregiver support (16.7%). The presence of these subgroups, which require confirmation and extension regarding potentially identifiable biological markers, may help individualizing treatment in patients with schizophrenia.

Use of ziprasidone in patients with schizophrenia in four European countries.

PURPOSE: To characterise patients with schizophrenia from four European countries treated with ziprasidone, and to compare these with patients treated with other second generation antipsychotics (SGAs) included in this survey. METHOD: A randomly selected, representative sample of psychiatrists (N = 744), from Germany, Greece, Italy and Spain, collected data on the five last patients with schizophrenia they had seen in consultation (N = 3996), including up to two patients treated with ziprasidone (N = 1096). RESULTS: Ziprasidone was most frequently prescribed to patients requiring a switch from another antipsychotic. Compared to other surveyed SGAs, ziprasisone was more likely to be prescribed to women than to men (OR: 1.52), to patients with mild disease than to those with severe disease (OR: 1.94) and to outpatients than to inpatients (1.30). The most frequently cited reasons for prescribing ziprasidone were good tolerability and efficacy against positive and negative symptoms. Compared to other SGAs included in this survey, it was more likely to be prescribed due to the low risk of weight gain, metabolic syndrome and extrapyramidal symptoms. CONCLUSION: Patients treated by ziprasidone more frequently belong to subgroups composed of more autonomous patients and those with mild to moderate disease severity.

Macroscopic small bowel mucosal injury caused by chronic nonsteroidal anti-inflammatory drugs (NSAID) use as assessed by capsule endoscopy.

OBJECTIVE: To evaluate the type, frequency, and severity of macroscopic small bowel mucosal injury after chronic NSAID intake as assessed by capsule endoscopy (CE), as well as to correlate the severity of gastroduodenal and intestinal damage in these patients. MATERIAL AND METHODS: A prospective, endoscopist-blind, controlled trial. Sixteen patients (14F/2M; age: 57.06 +/- 10.16 yrs) with osteoarthritis (OA) on chronic therapy with NSAIDs underwent CE and upper gastrointestinal endoscopy (UGE). Seventeen patients with OA (9F/2M; age: 57.47 +/- 9.82 yrs) who did not take NSAIDs were included as a control group. A scale ranging from 0 to 2 (0 = no lesions, 1-minor = red spots or petechiae, denuded areas and/or 1-5 mucosal breaks; 2-major = > 5 mucosal breaks and/or strictures, or hemorrhage) was designed to assess the severity of small bowel mucosal injuries. RESULTS: CE found intestinal lesions in 75% (12/16) of patients in the study group and in 11.76% (2/17) of controls (p < 0.01). Seven out of 16 NSAID consumers (43.75%) and none in the control group (0%) had a major small bowel mucosal injury (p < 0.01). The percentages of patients with grade 1 and 2 gastroduodenopathy in the study group, as assessed by UGE, were 37.14 and 23.81%, respectively. There was no significant difference in the rate of major enteropathy between patients with none or minor gastroduodenal injury, and those with major gastroduodenopathy (43.75 vs. 40%; p = N.S.). CONCLUSIONS: Chronic NSAID intake is associated with a high rate of small bowel mucosal injuries. Our data have failed to demonstrate a relationship between the severity of gastroduodenal and intestinal injury.

P300 event-related potential in euthymic patients with bipolar disorder.

Auditory P300 event-related potential (ERP) and performance on Sustained Attention were evaluated in 24 euthymic bipolar patients and 38 healthy volunteers. There were no significant differences between groups, and performance in sustained attention had no significant influence in the P300 responses. P300 response might be driven by the presence of mood symptoms.

[Splanchnic hemodynamic effects of somatostatin and octreotide in cirrhotic patients. A Doppler ultrasonographic study]. / Efecto hemodinámico esplácnico de somatostatina y octreótido en cirróticos. Estudio con ultrasonografía Doppler.

AIM: Doppler-ultrasound assessment of the splanchnic hemodynamic effects of intravenous somatostatin and octreotide administration. MATERIAL AND METHOD: Forty-five cirrhotic patients with esophageal varices were randomized to receive 1-hour intravenous somatostatin (SOM, 250 mg), octreotide (OCT, 50 mg), or placebo (PLA). In baseline and at 15, 30, 45 and 60 minutes of infusion, mean velocity, congestion index, flow volume and diameter of the portal vein, as well as the superior mesenteric artery resistivity index, were measured. Plasma bradykinine and vasoactive intestinal peptide (VIP) concentrations were also measured at baseline and at 30 and 60 minutes. RESULTS: While placebo caused no changes in any of the venous and arterial parameters, SOM and OCT caused a sustained decrease in portal vein velocity (-19.41 vs. -11.19%) and flow (-22.79 vs. -12.33%), and an increase in the congestion index (+17.5 vs. +7.5%) and resistivity index of the superior mesenteric artery (+7.18 vs. +6.16%) with respect to baseline (p < 0.05). These changes were already evident at 15 minutes and remained unchanged during the time of the study period. With respect to OCT, SOM caused a higher reduction in mean velocity and flow of the portal vein, with no significant differences for congestion index and mesenteric artery resistivity index, both increased by SOM and OCT. Plasma bradykinine and VIP concentrations remained unchanged in the three groups. CONCLUSIONS: At therapeutic doses, intravenous somatostatin and octreotide reduce portal vein velocity and flow, and increase portal vein congestion index and superior mesenteric artery resistivity index. Somatostatin causes a higher portal flow reduction than octreotide in spite of a similar splanchnic arterial effect.

Perfil de los pacientes ambulatorios con trastorno bipolar: un estudio transversal en la Comunidad de Madrid / Profile of bipolar disorder outpatients: a cross-sectional study in the Madrid Community

Introducción. El propósito de este estudio transversal es obtener un perfil de las características sociodemográficas, clínicas, de funcionamiento psicosocial y pautas terapéuticas de los pacientes con trastorno bipolar atendidos de forma ambulatoria en la Comunidad de Madrid. Metodología. Un total de 115 pacientes fueron incluidos en el estudio de forma consecutiva por 10 psiquiatras. Resultados. Desde el inicio de los síntomas hasta recibir un diagnóstico correcto de trastorno bipolar habían transcurrido una media de 7,6 años. La depresión fue la forma de inicio de la enfermedad en la mayoría de los pacientes, independientemente del subtipo. El 47% de los pacientes presentaba alguna sintomatología clínica sindrómica o subsindrómica, siendo depresiva la más predominante (33,1%). Una percepción subjetiva reducida de la calidad de vida se asoció a la presencia de síntomas depresivos y a una peor evolución el año previo. Más de la mitad del total de los pacientes (58,2%) se encontraban en una situación de sobrepeso u obesidad. El litio fue el estabilizador del humor más utilizado (71,3%), aunque el 41% de los pacientes recibía al menos tres psicofármacos. Conclusiones. Los resultados obtenidos en este estudio confirman en gran medida buena parte de los datos conocidos en la actualidad sobre el trastorno bipolar. Destaca la disminución en la calidad de vida de los pacientes bipolares relacionada con la presencia de síntomas depresivos. Se hace necesario optimizar los tratamientos en el trastorno bipolar para mejorar así su pronóstico (AU)

Introduction. The purpose of this cross-sectional study is to obtain a sociodemographic, clinical, psycho-social functioning and therapeutic profile of bipolar outpatients in the Madrid Community. Methods. A total of 115 outpatients were consecutively recruited by 10 psychiatrists. Results. Mean time between initial symptoms and an accurate bipolar diagnosis was of 7.6 years. A depressive episode was the onset of the illness in most patients independently of clinical subtype. Syndromal or subsyndromal symptoms were present in 47% of the patient population, dominating the depressive polarity (33.1 %). A subjectively reduced perception of quality of life was associated to the presence of depressive symptoms and a worse clinical outcome last year. More than half of the patients (58.2%) were overweight or obese. Lithium was the most frequently used mood stabilizer (71.3%), whereas41 % of the patients were taking at least three psychotropic drugs. Conclusions. Results of this study widely confirm previous data on bipolar disorder. Reduction in quality of life of bipolar patients associated to depressive symptoms must be highlighted. It is necessary to optimize treatments in bipolar disorder in order to improve prognosis (AU)
