RESUMO

The DDR1 locus is associated with the diagnosis of schizophrenia and with processing speed in patients with schizophrenia and first-episode psychosis. Here, we investigated whether DDR1 variants are associated with bipolar disorder (BD) features. First, we performed a case‒control association study comparing DDR1 variants between patients with BD and healthy controls. Second, we performed linear regression analyses to assess the associations of DDR1 variants with neurocognitive domains and psychosocial functioning. Third, we conducted a mediation analysis to explore whether neurocognitive impairment mediated the association between DDR1 variants and psychosocial functioning in patients with BD. Finally, we studied the association between DDR1 variants and white matter microstructure. We did not find any statistically significant associations in the case‒control association study; however, we found that the combined genotypes rs1264323AA-rs2267641AC/CC were associated with worse neurocognitive performance in patients with BD with psychotic symptoms. In addition, the combined genotypes rs1264323AA-rs2267641AC/CC were associated with worse psychosocial functioning through processing speed. We did not find correlations between white matter microstructure abnormalities and the neurocognitive domains associated with the combined genotypes rs1264323AA-rs2267641AC/CC. Overall, the results suggest that DDR1 may be a marker of worse neurocognitive performance and psychosocial functioning in patients with BD, specifically those with psychotic symptoms.

RESUMO

BACKGROUND: Recent research suggests that children born after suspected preterm labor may observe a potential cluster with different attention deficit hyperactivity disorder features, depending on the time of birth. However, the evolution of symptoms and their predictors remain unknown in this population. OBJECTIVE: This study aimed to examine the trajectories of attention deficit hyperactivity disorder symptoms of children born after suspected preterm labor, between ages 2 and 6 years, considering prematurity condition and comparing with controls. In addition, this study aimed to find potential modifiable predictors of evolution to enhance prognosis. STUDY DESIGN: In this prospective cohort study, 119 mother-child pairs who experienced suspected preterm labor and 60 controls were included. Patients were divided according to prematurity condition in full term (n=27), late preterm (n=55), and very preterm (n=37). Attention deficit hyperactivity disorder symptoms were assessed at ages 2 and 6 years. The association between potential modifying factors (group, time of assessment, sex, birthweight percentile, maternal history of trauma, maternal anxiety at diagnosis, and maternal anxiety during the children's assessments) and disorder trajectories was assessed by adjusting the Bayesian mixed linear models. All analyses were performed in R (version 4.3.0; R Foundation for Statistical Computing, Vienna, Austria). RESULTS: An interaction emerged between time and group, with late-preterm neonates born after suspected preterm labor being the only group to improve from ages 2 to 6 years (-2.26 points in Conners scale per percentile decrease and 0.98 probability of effect). Another interaction between time and maternal anxiety at postnatal time assessments intensified over time (0.07 and 0.84). Predictors of symptom severity included lower weight percentile at birth (-0.2 and 0.96), male sex (-2.99 and <0.99), higher maternal anxiety at diagnosis (+0.08 and 0.99), and maternal history of trauma (+0.23 and 0.98). CONCLUSION: Unlike very-preterm and full-term children, those born late preterm showed an improvement over time, probably because late-preterm children do not carry the sequelae derived from severe prematurity but benefit from close monitoring. As maternal psychopathology emerged as a determinant modifier of course and severity, it is crucial to develop targeted psychological interventions for pregnant individuals and reevaluate monitoring programs for their offspring, regardless of prematurity.

RESUMO

INTRODUCTION: Bipolar disorder (BD) has been reconceptualised as a progressive disorder that develops from mild to severe presentations. An empirical staging model - the Empirically Developed Clinical Staging Model for BD (EmDe-5) - was developed in a previous study. This study aims to further validate that model using a larger and more representative Spanish sample. MATERIAL AND METHODS: 183 BD outpatients were recruited at 11 sites in Spain. Assessment included clinical characteristics of the BD (number of hospitalisations, number of suicide attempts, comorbid personality disorders), physical health (BMI, metabolic syndrome, number of physical illnesses), cognition (SCIP), functioning (permanently disabled due to BD, FAST), and quality of life (SF-36). The CGI-S, VAS-S, and psychopharmacological treatment pattern were used as external validators. RESULTS: Ten patients (51.5%) were classified as stage 1, 33 (18%) as stage 2, 93 (508%) as stage 3, 37 (202%) as stage 4, and 10 (55%) as stage 5. All profilers, other than number of suicide attempts (p=0.311) and comorbid personality disorder (p=0.061), exhibited worse scores from stage 1 to 5. As expected, VAS-S and CGI-S scores were worse in the later stages. Regarding treatment, early stages (1-2) were associated with the use of one to three drugs while late stages (4-5) were associated with four or more drugs (p=0.002). CONCLUSIONS: We confirm the EmDe-5 staging model's construct validity. The ease of obtaining the profilers, together with the operational criteria provided to quantify them, will facilitate the use of the EmDe-5 staging model in daily clinical practice.

RESUMO

Fundamentos: Con la edad aumenta el consumo de fármacos, entre ellos los anticolinérgicos. La carga anticolinérgica es predictora decaídas, deterioro cognitivo y mortalidad, y su cálculo resulta de utilidad. El objetivo de este trabajo fue conocer la prevalencia del consumode anticolinérgicos y la carga anticolinérgica según diferentes escalas, así como las variables que influyen en la prevalencia y en la carga.Métodos: Se llevó a cabo un estudio analítico y transversal. La muestra fue obtenida por muestreo por conglomerados (nivel de confianza del95%, precisión del 3%) de pacientes de sesenta y cinco-ochenta años consultantes de un servicio de Urgencias. Las variables dependientes fueronlos fármacos anticolinérgicos consumidos y la carga anticolinérgica calculada mediante diez escalas:Anticholinergic Activity Scale (AAS);Anticholinergic Burden Classification (ABC);Anticholinergic Cognitive Burden Scale (ACB);Anticholinergic Drug Scale (ADS);Anticholinergic Load Scale (ALS);Anticholinergic Risk Scale (ARS);Clinician-Rated Anticholinergic Scale (CrAS);Chew’s scale (Chew);Drug Burden Index (DBI); yDuran’s scale (Duran).Las variables independientes fueron demográficas, patologías crónicas y fármacos consumidos. Como análisis estadístico se realizó la descripciónde variables y el estudio analítico a través de un análisis multivariante (análisis de regresión) para evitar factores de confusión.Resultados: Participaron 456 pacientes, y el consumo medio fue de siete fármacos (IC 95% 6,81-7,59). El 75,2% (IC 95%; 71%-79%) tomaban al-gún anticolinérgico; la media de anticolinérgicos fue de 1,91 (IC 95%; 1,75%-2,08%). Utilizando las escalas simultáneamente, el 58,1%, (IC 95%; 53,4%-62,5%) tenían alta carga anticolinérgica. Las escalas que más riesgo anticolinérgico detectaron fueron DBI (50,7%) y ALS (45,8%) y las que másalta carga, ABC (19,1%) y DBI (17,3%)...


Background: With age increases the consumption of drugs, including anticholinergics. The anticholinergic load is a predictor of falls, cognitiveimpairment and mortality, and its calculation is useful. The objectives of this paper was to know the prevalence of anticholinergic consumption andanticholinergic load according to different scales, and the variables that influence the prevalence and load.Methods: An analytical and cross-sectional study was carried out. The sample was obtained by cluster sampling (95% confidence level, 3%precision) of patients aged sixty-five/eighty consulting an emergency department. Dependent variables were Anticholinergic drugs consumed andanticholinergic load calculated using 10 scales:Anticholinergic Activity Scale (AAS);Anticholinergic Burden Classification (ABC);AnticholinergicCognitive Burden Scale (ACB);Anticholinergic Drug Scale (ADS);Anticholinergic Load Scale (ALS);Anticholinergic Risk Scale (ARS);Clinician-RatedAnticholinergic Scale (CrAS);Chew’s scale (Chew);Drug Burden Index (DBI); andDuran’s scale (Duran). Independent variables were demographics,chronic pathologies and drugs consumed. Statistical analysis: description of variables and analytical study through a multivariate analysis (regres-sion analysis) to avoid confounding factors.Results: 456 patients participated, mean consumption was seven drugs (95% CI 6.81-7.59). 75.2% (95% CI 71%-79%) were taking someanticholinergic; mean of anticholinergics of 1.91 (95% CI 1.75%-2.08%). Using the scales simultaneously, 58.1% (95% CI 53.4%-62.5%) had a highanticholinergic load. The scales that detected the highest anticholinergic risk were DBI (50.7%) and ALS (45.8%), and those with the highest, ABCload (19.1%) and DBI (17.3%)...(AU)

RESUMO

Canalization of vascular accesses is one of the most used techniques in hospitalization units. When talking about peripherally inserted catheters, we can differentiate between peripheral intravenous catheters (PIVC), midline catheters, and long peripheral catheters (LPC). Midline catheters are rarely used despite being recommended for intravenous therapies lasting more than six days. This research is a pilot study of a longitudinal clinical trial. It aims to compare the complications associated with intravenous therapy between the control group (CG) with a PIVC and the experimental group (EG) with a midline in an Internal Medicine Unit of a Spanish hospital for three months. In this study, 44 subjects participated, 25 in the CG and 19 in the EG. The duration of cannulation was longer in the experimental group (8.13 days vs. 3.22, p < 0.001), and the appearance of phlebitis was more significant in the control group (19 patients in CG and 25 patients in EG). Midlines have presented a longer duration of cannulation and fewer complications than the PIVC. This protocol was registered with ClinicalTrials.gov (NCT05512117).

RESUMO

The similarity between retinal cells and neurons of the central nervous system allows non-invasive methods to study retinal function, such as the Electroretinogram-Pattern (PERG) to be postulated as possible biomarkers, useful and safe in the study of psychiatric pathologies such as Bipolar Disorder (BD). The objective of the present study is to characterize the differences in the results in the PERG of patients with BD and healthy subjects, as well as to evaluate a possible correlation between these results and the affective decompensations of the manic pole in the group of bipolar patients.

RESUMO

Sexual functioning in bipolar disorder (BD) is dependent on multiple clinical and demographic determinants that can eventually lead to sexual dysfunction. However, the contribution of affective temperaments remains unstudied in this population. In this cross-sectional multicentric work, we studied the impact of temperament traits on sexual functioning in 100 euthymic BD outpatients treated only with mood stabilizers with or without benzodiazepines. Temperament was evaluated using the Temperament Evaluation of Memphis, Pisa, Paris, and San Diego - Autoquestionnaire (TEMPS-A) and sexual functioning with the Changes on Sexual Functioning Questionnaire (CSFQ-14). The effect of temperament on sexual functioning was analyzed using Bayesian ordinal regression models, which included age, gender, BD type, dominant polarity, metabolic syndrome, marital status, and affective symptomatology. Our results showed that hyperthymic traits predicted a significantly higher CSFQ-14 score for global sexual functioning (OR = 1.222; 95% CI [1.073, 1.431]), desire (OR = 1.164; 95% CI [1.025, 1.357]), arousal (OR = 1.278; 95% CI: [1.083, 1.551]), and orgasm (OR = 1.182; 95% CI [1.037, 1.365]). We did not find a significant contribution for other types of temperaments. Better sexual functioning was also associated with a better quality of life. Our findings highlight the importance of temperament traits in sexual functioning in euthymic BD, which may have implications in sexual dysfunction prevention.

RESUMO

Introducción. La similitud entre las células retinianas y las neuronas del sistema nervioso central permite que métodos no invasivos de estudio de la función retiniana, como el Electrorretinograma-Patrón (PERG) se postulen como posibles biomarcadores, útiles y seguros en el estudio de patologías psiquiátricas como el Trastorno Bipolar (TB). El objetivo del presente estudio es caracterizar las diferencias en los resultados en el PERG de pacientes con TB y sujetos sanos, así como evaluar una posible correlación entre estos resultados y las descompensaciones afectivas del polo maniaco en el grupo de pacientes bipolares. Material y métodos. Se realizó un estudio transversal en una muestra de 34 pacientes bipolares en diferentes estados clínicos y 36 controles sanos. Se recogieron las variables independientes: sexo, edad, fármacos y estado clínico, medidas mediante escalas validadas y posteriormente se realizó el PERG obteniendo la variable dependiente de interés, la amplitud media de la onda P50. Resultados. Existe una diferencia estadísticamente significativa en los resultados del PERG entre pacientes con TB y controles, y también entre los diversos estados clínicos de los pacientes con TB. Asimismo, encontramos una correlación negativa entre la gravedad de la manía, y la amplitud media de la onda P50. Conclusiones. Las diferencias encontradas, tanto entre sujetos sanos y pacientes bipolares, como entre los estados afectivos dentro del TB, sugieren que las alteraciones en la función retiniana, medidas mediante PERG, pueden ser un prometedor biomarcador de rasgo y de estado en TB.(AU)

Material and methods. A cross-sectional study was carried out in a sample of 34 bipolar patients in different clinical states and 36 healthy controls. The independent variables were collected: sex, age, drugs and clinical status, measured using validated scales and later the PERG was performed, obtaining the dependent variable of interest, the mean amplitude of the P50 wave. Results. There is a statistically significant difference in the PERG results between BD patients and controls, and also between the various clinical states of BD patients. Likewise, we found a negative correlation between the severity of the mania and the mean amplitude of the P50 wave. Conclusions. The differences found, both between healthy subjects and bipolar patients, and between affective states within BD, suggest that alterations in retinal function, measured by PERG, may be a promising biomarker of trait and status in BD.(AU)

RESUMO

Despite schizophrenia (SZ) is characterized by a high psychopathological heterogeneity, the underlying psychological mechanisms that result in different clinical profiles are unclear. This study examined the cognitive processing of emotional faces (angry, happy, neutral, and sad) by means of assessing inhibitory control (antisaccade task) and attentional engagement (prosaccade task) with the eye-tracking paradigm. Firstly, two clinical SZ subgroups classified according to the predominance of positive (PSZ; n = 20) or negative symptoms (NSZ; n = 34) and a control group of 32 individuals were compared. Secondly, the association between prosaccade and antisaccade measurements and the severity of positive and negative symptoms were analyzed. The PSZ group showed slower antisaccades when angry faces were displayed, and higher positive symptoms were associated with slower prosaccade latencies to ones. Conversely, the NSZ group made overall slower prosaccades with an emotional advantage for angry faces, and higher negative symptoms were associated with faster antisaccade latencies to ones. Hence, whereas positive SZ profile is related to a lack of attentional engagement and an impaired inhibitory control to threatening information; negative SZ profile is linked to a lack of attentional engagement to faces, mainly with non-threat ones, and with an advantage to ignore distracting threatening stimuli. These findings support affective information-processing theories suggesting a hypersensitivity to threat for positive SZ profiles, and a desensitization to socio-emotional information for negative ones. Consequently, characterizing psychological mechanisms of SZ may allow improving current treatments to threat management when positive symptoms are predominant, or emotion sensitization when negative symptoms prevail.

RESUMO

BACKGROUND: Bipolar disorder (BD) is characterized by mood changes that implies alterations in reward sensitivity and frustration tolerance. This study examined the effects of monetary reward and frustration on attentional performance and on affective experience across mood states in BD. METHODS: An Affective Posner Task in which the nature of contingencies are divided in the three successive blocks (baseline condition, monetary reward and non-contingent feedback) was applied to BD individuals in their different episodes: mania (n = 30), depression (n = 30), and euthymia (n =  30) as well as to a group of healthy controls (n = 30). RESULTS: Monetary reward improved performance (in terms of faster response times) in the euthymic group and the control group, whereas it impaired performance in the manic group and has not significant effect in the depressed group. In addition, an increased interference of frustration on response accuracy was exhibited in the three groups of BD patients (including euthymia) compared with healthy controls. LIMITATIONS: Participants' affective experience was self-informed by a Likert scale, so the reliability of this measure can be undermined in symptomatic patients in terms of stability and objectivity. Although it was statistically controlled, at the time of testing, all BD patients were medicated. CONCLUSIONS: A dissociated effect of reward and frustration was found between symptomatic and euthymic states in BD: whereas the benefit from monetary reward is affected only during symptomatic episodes (i.e., a state), the notably increased interference of frustration is exhibited also during euthymia (i.e., a trait).

RESUMO

OBJECTIVES: Neutrophil-lymphocyte ratio (NLR), platelet-lymphocyte ratio (PLR), and C-Reactive Protein (CRP) are markers of inflammation that are elevated in bipolar disorder (BD) and are also related to a higher risk of metabolic syndrome (MetS). This study aimed at investigating for the first time the association between NLR, PLR, and CRP and the metabolic status in BD. METHODS: We assessed the association between biomarkers and the metabolic status: number of metabolic risk factors, presence of MetS, insulin sensitivity (Quantitative Insulin Sensitivity Check Index, QUICKI) and insulin resistance (Homeostatic Model Assessment for Insulin Resistance, HOMA-IR index), in a sample of 219 outpatients with BD. RESULTS: 25.9% of the sample met the criteria for MetS. High levels of CRP were found in 12% of the sample. Older age, low PLR, high NLR, and high CRP levels significantly predicted a higher number of MetS risk factors (p < 0.001). Older age and low PLR were associated with a greater likelihood of developing MetS (p = 0.007). CONCLUSIONS: Although further studies are needed to replicate and validate these findings, inflammatory biomarkers as CRP, PLR and NLR could be useful tools to identify patients with a BD at risk for a metabolic adverse outcome.

RESUMO

(1) Background: Nurses can find people with advanced diseases or in their last days of life during their professional careers and in many different care settings. For this reason, they need to have at least a basic level of palliative care education since they are the professional cohort treating these patients in a very close way. This research aims to determine the level of knowledge in palliative care of Spanish nurses and establish any possible difference based on their experience and training in palliative care. (2) Methods: A cross-sectional design using survey methods (distributed an online questionnaire) aimed at Spanish registered nurses. A validated questionnaire (PCQN-SV) was used to determine the level of knowledge in palliative care; information on some variables to characterize the population was also collected (experience and education in palliative care, years of professional experience, academic level, and others). Uni and bivariate descriptive analyses were performed. A binary logistic regression model was also developed to identify those variables that influenced obtaining results higher than the population's average. (3) Results: Spanish nurses have a medium-low level of knowledge in palliative care, higher in those who have previous experience or education in this area. Statistically significant differences were also found according to the area in which their caring activity was developed. (4) Conclusions: It is necessary to implement strategies for the basic training of nursing professionals in palliative care to offer quality care to people in advanced stages of illnesses or at the end of their lives.

RESUMO

Attentional biases to threatening stimuli have been suggested to play a key role in the onset and course of schizophrenia. However, current research has not completely demonstrated this assumption. The aim of this eye-tracking study was to shed light on the underlying psychological mechanisms of schizophrenia by examining the attentional processing of socio-emotional information. Forty-four individuals with schizophrenia and 47 healthy controls were assessed in a 3-s free-viewing task with a social scene (i.e., happy, threatening, or neutral) in competition with a non-social one to determine the effects of emotional information on the different stages of the attentional processing. The location and latency of initial fixations (i.e., initial orienting), the firs-pass fixations and gaze duration (i.e., attentional engagement), and the percentage of total duration and total fixations (i.e., attentional maintenance) were analyzed. It was found that the schizophrenia group showed longer first-pass gaze duration, as well as higher percentage of total fixations and total duration toward threatening scenes in relation to the non-social ones, compared to controls. Therefore, an attentional bias toward threatening scenes in schizophrenia was found in the attentional maintenance and engagement, but not in the initial orienting of attention. Of note, the threat-related attentional bias was not associated with positive symptoms of schizophrenia. These findings offer empirical support to affective-information processing models stating that threatening information may confer psychological vulnerability to develop schizophrenia. Moreover, the results can improve psychological treatments, such as attentional bias modification paradigms or cognitive-behavior interventions managing maladaptive schemas related to threat.

RESUMO

Diclofenac (DCF), 17-ß-estradiol (E2), and 17-α-ethinylestradiol (EE2) are emerging pollutants included in the first watch list agreed by European countries and set in the EU Water Directive. The objective of the present study was the analytical monitoring of DCF, E2, and EE2 in surface water and sediment of the Manzanares River in a stretch that crosses the city of Madrid, Spain, and to assess whether such environmental levels could affect the development of aquatic vertebrates through a zebrafish embryo-larval assay. Samples taken during two campaigns in the spring of 2015 were analyzed for DCF, E2, and EE2 by LC-MS or GC-MS. The levels of E2 and EE2 measured in surface water and sediments of the Manzanares were within the ranges reported in other Spanish and European studies; however, DCF levels were higher in the present study. The zebrafish embryos exposed to the Manzanares River water (0-144h) showed lethal effects and sublethal effects (developmental delay, bradycardia, and reduced locomotion). Nevertheless, these effects were not primarily associated with the levels of DCF, E2, and EE2 present in the Manzanares River, because representative mixtures of the field study prepared in the laboratory did not exhibit such toxicity to the zebrafish embryos.

RESUMO

Attentional biases to emotional information may play a key role in the onset and course of schizophrenia. The aim of this experiment was to examine the attentional processing of four emotional scenes in competition (happy, neutral, sad, threatening) in 53 patients with schizophrenia and 51 controls. The eye movements were recorded in a 20-seconds free-viewing task. The results were: (i) patients showed increased attention on threatening scenes, compared to controls, in terms of attentional engagement and maintenance; (ii) patients payed less attention to happy scenes than controls, in terms of attentional maintenance; (iii) whereas positive symptoms were associated with a late avoidance of sad scenes, negative symptoms were associated with heightened attention to threat. The findings suggest that a threat-related bias and a lack of sensitivity to positive information may represent an underlying psychological mechanism of schizophrenia. Importantly, schizophrenia symptoms modulated the attentional biases, which has aetiological and therapeutic implications.

RESUMO

OBJECTIVE: Neurocognitive dysfunction is a common feature of bipolar disorder even in euthymia, and psychopharmacological treatment could have an effect on cognition. Long-term prescription of benzodiazepines in bipolar disorder is a common practice, and their effect on neurocognition has not been well studied in this population. The aim of this study was to evaluate the impact of concomitant benzodiazepine long-term use on neurocognitive function in stable euthymic bipolar disorder patients. METHODS: Seventy-three euthymic bipolar disorder outpatients and 40 healthy individuals were assessed using a neurocognitive battery. Patients were classified in two groups according to the presence of benzodiazepines in their treatment: the benzodiazepine group (n = 34) and the non- benzodiazepine group (n = 39). Neurocognitive performance was compared between the groups using a multivariate analysis of covariance, considering age, number of depressive episodes, adjuvant antipsychotic drugs, Young Mania Rating Scale score and Hamilton Depression Rating Scale score as covariates. RESULTS: Both bipolar disorder groups (benzodiazepine and non-benzodiazepine) showed an impairment in memory domains (Immediate Visual Memory [p = 0.013], Working Memory [p < 0.001], and Letter-Number Sequence [p < 0.001] from the Wechsler Memory Scale-Revised-III) and slower processing speed functions (Stroop Colour [p < 0.001]) relative to the control group. Nevertheless, the benzodiazepine group showed a greater impairment in executive functions (Conceptual Level Responses [p = 0.024] from the Wisconsin Card Sorting Test and Frontal Assessment Battery [p = 0.042]). CONCLUSION: Although memory and processing speed impairments were found in bipolar disorder, regardless of their benzodiazepine treatment, benzodiazepine users presented additional neurocognitive impairments in terms of executive functioning. These findings support restricted prescription of benzodiazepines in individuals with bipolar disorder.

RESUMO

Introduction There is scarce real-world experience regarding direct oral anticoagulants (DOACs) perioperative management. No study before has linked bridging therapy or DOAC-free time (pre-plus postoperative time without DOAC) with outcome. The aim of this study was to investigate real-world management and outcomes. Methods RA-ACOD is a prospective, observational, multicenter registry of adult patients on DOAC treatment requiring surgery. Primary outcomes were thrombotic and hemorrhagic complications. Follow-up was immediate postoperative (24-48 hours) and 30 days. Statistics were performed using a univariate and multivariate analysis. Data are presented as odds ratios (ORs [95% confidence interval]). Results From 26 Spanish hospitals, 901 patients were analyzed (53.5% major surgeries): 322 on apixaban, 304 on rivaroxaban, 267 on dabigatran, 8 on edoxaban. Fourteen (1.6%) patients suffered a thrombotic event, related to preoperative DOAC withdrawal (OR: 1.57 [1.03-2.4]) and DOAC-free time longer than 6 days (OR: 5.42 [1.18-26]). Minor bleeding events were described in 76 (8.4%) patients, with higher incidence for dabigatran (12.7%) versus other DOACs (6.6%). Major bleeding events occurred in 17 (1.9%) patients. Bridging therapy was used in 315 (35%) patients. It was associated with minor (OR: 2.57 [1.3-5.07]) and major (OR: 4.2 [1.4-12.3]) bleeding events, without decreasing thrombotic events. Conclusion This study offers real-world data on perioperative DOAC management and outcomes in a large prospective sample size to date with a high percentage of major surgery. Short-term preprocedural DOAC interruption depending on the drug, hemorrhagic risk, and renal function, without bridging therapy and a reduced DOAC-free time, seems the safest practice.

RESUMO

BACKGROUND: In addition to factors intrinsic to bipolar disorder (BD), sexual functioning (SF) can be affected by extrinsic causes, such as psychotropic drugs. However, the effect of mood stabilizers on SF and quality of life (QoL) is an underexplored research area. AIM: To analyze SF in BD outpatients in euthymia for at least 6 months treated only with mood stabilizers and the association between SF and QoL. METHODS: A multicenter cross-sectional study was conducted in 114 BD outpatients treated with (i) lithium alone (L group); (ii) anticonvulsants alone (valproate or lamotrigine; A group); (iii) lithium plus anticonvulsants (L+A group); or (iv) lithium plus benzodiazepines (L+B group). The Changes in Sexual Functioning Questionnaire Short Form (CSFQ-14) was used. Statistical analyses were performed to compare CSFQ-14 scores among the pharmacological groups. An adaptive lasso was used to identify potential confounding variables, and linear regression models were used to study the association of the CSFQ-14 with QoL. MAIN OUTCOME MEASURES: Self-reports on phases of the sexual response cycle (ie, desire, arousal, and orgasm) and QoL were assessed. RESULTS: The A group had better total SF scores than the L group and the L+B group. Relative to the A group, the L and L+B groups had worse sexual desire; the L group had worse sexual arousal; and the L+A group and the L+B group had worse sexual orgasm. Regarding sociodemographic factors, being female and older age were associated with worse total SF and all subscale scores. Among all subscales scores, higher sexual arousal scores were associated with better QoL. CLINICAL IMPLICATIONS: Potential modified extrinsic factors such as psychotropic medication that can affect SF can be addressed and adjusted to lessen side effects on SF. STRENGTHS & LIMITATIONS: Sample of patients with euthymic BD in treatment with mood stabilizers and no antipsychotics or antidepressants, substance use as an exclusion criterion, and use of a validated, gender-specific scale to evaluate SF. Major limitations were cross-sectional design, sample size, and lack of information about stability of relationship with partner. CONCLUSIONS: Lithium in monotherapy or in combination with benzodiazepines is related to worse total SF and worse sexual desire than anticonvulsants in monotherapy. While the addition of benzodiazepines or anticonvulsants to lithium negatively affects sexual orgasm, sexual arousal (which plays a significant role in QoL) improves when benzodiazepines are added to lithium. Anticonvulsants in monotherapy have the least negative effects on SF in patients with BD. García-Blanco A, García-Portilla MP, Fuente-Tomás L de la, et al.
