RESUMO

Background and Hypothesis: People with serious mental illness (SMI; psychotic and affective disorders with psychosis) are at an increased risk of suicide, yet there is limited research on the correlates of suicide in SMI. Social cognitive impairments are common among people with SMI and several studies have examined social cognition and suicidal ideation (SI) and behavior. This systematic review aims to evaluate the links between various domains of social cognition, SI, and suicidal behavior in SMI. Study Design: Electronic databases (PubMed and PsycInfo) were searched through June 2023. Records obtained through this search (N = 618) were screened by 2 independent reviewers according to inclusion criteria. Relevant data were extracted, and study quality was assessed. Study Results: Studies (N = 16) from 12 independent samples were included in the systematic review (N = 2631, sample sizes ranged from N = 20 to N = 593). Assessments of social cognition and SI and behavior varied widely between studies. Broadly, effects were mixed. Better emotion recognition of negative affect was linked to SI and a history of suicide attempts, though there is little consistent evidence for the relationship of emotion recognition and SI or behavior. On the other hand, better theory of mind ability was linked to SI and a history of suicide attempts. Furthermore, negative attributional bias was linked to current SI, but not a history of SI or attempt. Conclusions: This review suggests mixed associations between social cognition, SI, and behavior in SMI. Future research should evaluate additional mediators and moderators of social cognition and suicide, employing prospective designs.

RESUMO

Background: Antipsychotics and mood stabilisers are gathering attention for the disturbance of metabolism. This network meta-analysis aims to evaluate and rank the metabolic effects of the commonly used antipsychotics and mood stabilisers in treating bipolar disorder (BD). Methods: Registries including PubMed, Embase, Cochrane Library, Web of Science, Ovid, and Google Scholar were searched before February 15th, 2024, for randomised controlled trials (RCTs) applying antipsychotics or mood stabilisers for BD treatment. The observed outcomes were twelve metabolic indicators. The data were extracted by two reviewers independently, and confirmed by another four reviewers and a corresponding author. The above six reviewers all participated in data analyses. Data extraction was based on PRISMA guidelines, and quality assessment was conducted according to the Cochrane Handbook. Use a random effects model for data pooling. The PROSPERO registration number is CRD42023466669. Findings: Together, 5421 records were identified, and 41 publications with 11,678 complete-trial participants were confirmed eligible. After eliminating possible sensitivity, risperidone ranked 1st in elevating fasting serum glucose (SUCRA = 90.7%) and serum insulin (SUCRA = 96.6%). Lurasidone was most likely to elevate HbA1c (SUCRA = 82.1%). Olanzapine ranked 1st in elevating serum TC (SUCRA = 93.3%), TG (SUCRA = 89.6%), and LDL (SUCRA = 94.7%). Lamotrigine ranked 1st in reducing HDL (SUCRA = 82.6%). Amisulpride ranked 1st in elevating body weight (SUCRA = 100.0%). For subgroup analyses, quetiapine is more likely to affect indicators of glucose metabolism among male adult patients with bipolar mania, while long-term lurasidone tended to affect glucose metabolism among female patients with bipolar depression. Among patients under 18, divalproex tended to affect glucose metabolism, with lithium affecting lipid metabolism. In addition, most observed antipsychotics performed higher response and remission rates than placebo, and displayed a similar dropout rate with placebo, while no between-group significance of rate was observed among mood stabilisers. Interpretation: Our findings suggest that overall, antipsychotics are effective in treating BD, while they are also more likely to disturb metabolism than mood stabilisers. Attention should be paid to individual applicability in clinical practice. The results put forward evidence-based information and clinical inspiration for drug compatibility and further research of the BD mechanism. Funding: The National Key Research and Development Program of China (2023YFC2506200), and the Research Project of Jinan Microecological Biomedicine Shandong Laboratory (No. JNL-2023001B).

RESUMO

INTRODUCTION: The paradigm in mental health care is progressively moving towards a recovery-focused perspective. Thus, there is a need for validated instruments to measure recovery in bipolar disorder (BD). The Bipolar Recovery Questionnaire (BRQ) is the most used instrument to assess it. The aim of this study was to translate and perform a cross-cultural adaptation of the BRQ to European Portuguese (PT-PT) and to explore further associations of recovery with sociodemographic and emotional regulation, as well as recovery predictors to inform future research and clinical practice. METHODS: The BRQ was forward-translated and back-translated until a consensus version was found, and a test-retest design was used to assess temporal stability. Participants were recruited in public hospitals and organizations supporting people with BD, either referred by their psychiatrists or psychologists or through self-referral. Eighty-eight individuals diagnosed with BD were recruited to complete a battery of Portuguese-validated self-report questionnaires to assess recovery (BRQ), clinical mood symptoms (Hospital Anxiety and Depression Scale), affect (Positive and Negative Affect Scale), well-being (brief Quality of Life for Bipolar Disorder; Satisfaction with Life Scale) and emotion regulation (Difficulties in Emotion Regulation Scale). RESULTS: The BRQ showed excellent internal consistency with a Cronbach alpha of 0.92, and test-retest exhibited good reliability (r = 0.88). Construct validity was confirmed through/by positive and moderate correlations with quality of life (QoL; r = 0.58) and positive affect (r = 0.52), and negative moderate correlations with depression (r = -0.64), and negative affect (r = -0.55). Both satisfaction with life (ß = 0.38, p = 0.010) and recovery (ß = 0.34, p = 0.022) impacted quality of life, supporting the BRQ's incremental validity. Depressive symptoms and emotion dysregulation accounted for 51% of its variance. CONCLUSION: The BRQ is a valid and reliable instrument to measure recovery in people with BD in the Portuguese population and is suitable for both clinical and research contexts.

RESUMO

OBJECTIVE: Divergent thinking is a critical creative cognitive process. Its neural mechanisms have been well-studied through structural and functional imaging in healthy individuals but are less explored in patients with bipolar disorder (BD). Because of the traditional link between creativity and BD, this study investigated the structural correlates of divergent thinking in patients with BD through surface-based morphometry. METHODS: Fifty-nine patients diagnosed with BD I or BD II (35.3 ± 8.5 years) and 56 age- and sex-matched controls (33.9 ± 7.4 years) were recruited. The participants underwent structural magnetic resonance imaging and an evaluation of divergent thinking by using the Chinese version of the Abbreviated Torrance Test for Adults (ATTA). FreeSurfer 7.0 was used to generate thickness and surface area maps for each participant. Brainwise regression of the association between cortical thickness or surface area and ATTA performance was conducted using general linear models. RESULTS: Divergent thinking performance did not differ significantly between the patients with BD and the healthy controls. In these patients, total ATTA score was negatively correlated with cortical thickness in the right middle frontal gyrus, right occipital, and left precuneus but positively correlated with the surface area of the right superior frontal gyrus. By contrast, total ATTA scores and cortical thickness or surface area were not significantly correlated among the controls. CONCLUSION: The findings indicate that divergent thinking involves cerebral structures for executive control, mental imagery, and visual processing in patients with BD, and the right prefrontal cortex might be the most crucial of these structures.

RESUMO

Electrochemistry-based light-emitting devices have gained considerable attention in different applications such as sensing and optical imaging. In particular, such systems are an interesting alternative for the development of multimodal light-emitting platforms. Herein we designed a multicolor light-emitting array, based on the electrochemical switch-on of light-emitting diodes (LEDs) with a different intrinsic threshold voltage. Thermodynamically and kinetically favored coupled redox reactions, i.e. the oxidation of Mg and the reduction of protons on Pt, act as driving force to power the diodes. Moreover, this system enables to trigger an additional light emission based on the interfacial reductive-oxidative electrochemiluminescence (ECL) mechanism of the Ru(bpy)32+/S2O82- system. The synergy between these light-emission pathways offers a multimodal platform for the straightforward optical readout of physico-chemical information based on composition changes of the solution.

RESUMO

Background: Obesity is a risk factor for atrial fibrillation (AF). Data regarding left atrial (LA) remodeling in obese patients are scarce. Whether obesity favors AF recurrence after catheter ablation (CA) is still controversial. We assessed the distribution of epicardial atrial fat on computed tomography (CT), LA bipolar voltage, low-voltage zone (LVZ) extent, and the outcome of voltage-guided ablation of persistent AF in obese and non-obese patients. Methods: A total of 139 patients with persistent AF undergoing a first voltage-guided ablation were enrolled and divided into two groups: 74 were non-obese and 65 were obese. Epicardial adipose tissue (EAT) was assessed on a CT scanner. LA endocardial voltage maps were obtained using a 3D mapping system in sinus rhythm. LVZ was defined as a bipolar peak-to-peak voltage amplitude <0.5 mV. Results: LA volume, voltage, and EAT amount were similar in the two groups. LVZ was less frequent in obese patients [12 (18.8%) vs. 26 (35.1%), p = 0.05], particularly on the anterior wall. The posterior and lateral EATs were correlated with posterior and lateral LVZ extent, respectively, in obese patients. After 36 months of follow-up, the AF-free survival rate was similar. Lateral EAT [odds ratio (OR) 1.21, 95% confidence interval (CI) 1-1.4, p = 0.04] and P-wave duration (OR 1.03, 95% CI 1-1.05, p = 0.03), but not body mass index (BMI), were predictors of AF recurrence after CA. Conclusion: In obese patients, LVZ was less marked than in non-obese patients with similar LA volumes, voltage, and EAT amounts. In obese patients, posterior and lateral EATs were correlated with posterior and lateral LVZ extents. Obese patients had a similar and favorable 36-month outcome after AF ablation. BMI was not predictive of AF recurrence.

RESUMO

Background: Surgery is effective for extracranial internal carotid artery (EICA) aneurysms. However, the risk of cranial nerve injury associated with surgical repair, such as graft-assisted resection and extracranial-intracranial bypass techniques, is relatively high. Here, we report two cases of surgical treatment for EICA aneurysms and describe the surgical techniques and strategies to avoid cranial nerve injury. Methods: Two patients presented to our facility with an increasing cervical pulsatile mass and no neurological symptoms. Angiography showed a large aneurysm in the cervical internal carotid artery. Surgical treatment was performed to prevent rupture of the aneurysm. In both patients, the aneurysm was strongly attached to the vagus nerve. The aneurysm and vagus nerve were carefully dissected using a low-power bipolar (20 Malis; 3 watts), leaving connective tissue on the vagus nerve side. Results: The aneurysm was detached from the vagus nerve without injury. Based on intraoperative findings, one patient underwent clipping, and the other underwent aneurysmectomy and primary closure for aneurysm obliteration and angioplasty. Both patients were discharged without any cranial nerve dysfunction. Conclusion: The selection of a strategy based on intraoperative findings and low-power bipolar cutting is important for the treatment of extracranial carotid artery aneurysms to preserve cranial nerves.

RESUMO

The aim of this systematic literature review was to investigate the role of the cerebellum in the affective symptoms observed in patients with bipolar disorder. The present systematic literature review included clinical studies conducted from 2013-2023 among adult populations with bipolar I and II disorders, along with their specifiers. With regard to cerebellar pathology, it was found that those with bipolar disorder performed worse than their healthy counterparts in their ability to comprehend the mental states of others and in identifying negative mental states. Additionally, individuals with bipolar disorder had reduced gray matter loss in regions such as lobules I-IX, crus I, and crus II, different functional activation patterns of the thalamus, striatum, and hippocampus on functional magnetic resonance imaging (fMRI), and increased cortical thickness. Cerebro-cerebellar functional connectivities were altered in patients with bipolar disorder. The effects of lamotrigine and lithium on cerebellar volume and abnormalities are also discussed in this paper. The present systematic literature review illustrates the emerging involvement of the cerebellum in bipolar disorder and its affective symptoms and paves the way for future research and a better understanding of bipolar disorder.

RESUMO

Studies have revealed that individuals with bipolar I and bipolar II have a past of substance abuse. The co-occurrence of bipolar disorder and alcoholism is frequent. Although various arguments have been put forward to explain the relationship between these disorders, it is still not fully understood. Since substance abuse is prevalent among bipolar patients, it would be beneficial to investigate the impact of substance abuse on clinical characteristics, as well as the progression of the illness. Thus, this study was carried out to investigate a case of alcohol dependence with bipolar disorder. A 49-year-old male visited the psychiatry outpatient department and then was admitted. The patient's chief complaints were alcohol consumption, cigarette smoking, daily drinking for 35 years, irritability/aggressiveness, boastful talk, overspending, and decreased need for sleep from the last 20 days. According to the literature, self-medicating with alcohol is not an effective treatment for alcoholism, unless it is being used to alleviate the psychological and neurochemical effects caused by alcohol. However, there has been limited research on how to treat individuals who have both alcoholism and another medical condition. A few studies have looked at the impact of medications like valproate, lithium, and naltrexone, as well as psychosocial interventions, in treating patients with bipolar disorder and alcoholism. However, more research is necessary to fully understand the best approach.

RESUMO

Motivational deficits and reduced goal-directed behavior for external rewards have long been considered an important features of negative symptoms in patients with schizophrenia (SCZ). Negative symptoms have also a high prevalence in bipolar disorder (BP). We used a transdiagnostic approach in order to examine association between negative symptoms and effort allocation for monetary rewards. 41 patients with SCZ and 34 patients with BP were enrolled in the study along with 41 healthy controls (HC). Effort-Expenditure for Rewards Task (EEfRT) was used to measure subjects' effort allocation for monetary rewards. Generalized estimating equation models were used to analyze EEfRT choice behavior. Negative symptoms were assessed using the Brief Negative Symptom Scale (BNSS). SCZ and BP groups expended lower effort to obtain a monetary rewards compared to HC. Severity of negative symptoms was negatively correlated with EEfRT performance in both diagnostic groups. Each diagnostic group showed lower effort allocation for monetary rewards compared to HC suggesting reduced motivation for monetary rewards. In addition, our results suggest that abnormal effort-based decision-making might be a transdiagnostic factor underlying negative symptoms.

RESUMO

INTRODUCTION: Cariprazine treats acute manic and depressive episodes in bipolar I disorder (BP-I), but its efficacy in preventing relapse of mood episode remains unknown. METHODS: In this phase 3b, double-blind, placebo-controlled study, patients with BP-I with acute manic or depressive episodes (each with/without mixed features), were treated with cariprazine 3.0 mg/day during a 16-week open-label treatment period; those who achieved stable remission within 8 weeks and remained stable for at least another 8 weeks were randomized to receive cariprazine 1.5 or 3.0 mg per day or placebo in the double-blind treatment period for up to 39 weeks. The primary efficacy endpoint was time to relapse of any mood episode. Adverse events (AEs) were assessed. RESULTS: Patients (440/896) enrolled in the open-label treatment period achieved stability criteria and were randomized to receive cariprazine 3.0 mg/day (n = 148), cariprazine 1.5 mg/day (n = 147), or placebo (n = 145) in the double-blind treatment period. Relapse rates were 17.9%, 16.8%, and 19.7% in the cariprazine 3.0 mg/day, cariprazine 1.5 mg/day, and placebo groups, respectively. Neither dose of cariprazine was more effective than placebo on the primary outcome (3.0 mg/day: HR = 0.89, [95% CI: 0.5, 1.5]; 1.5 mg/day: HR = 0.83, 95% CI [0.5, 1.4]). The most frequently reported AEs (≥5%) were akathisia, headache, insomnia, and nausea in the open-label treatment period and increased weight and insomnia in the double-blind treatment period. In the open-label and double-blind treatment periods, 7.5% and 1.6% of patients experienced an AE leading to discontinuation. CONCLUSION: Cariprazine was not superior to placebo in the prevention of relapses in this study. Relapse rates were unusually low in the placebo group. Cariprazine was well-tolerated.

RESUMO

There is a dearth of studies on neuroimaging correlates of Bipolar Disorder (BD) in Multiple Sclerosis (MS). We describe the clinical profile and neuroimaging findings of four cases of MS with BD. Among them, two patients had multiple mood episodes preceding the neurological symptoms, one had concurrent manic and neurological symptoms, and one had multiple depressive episodes and an isolated steroid-induced manic episode. Frontal and temporal lobes, and Periventricular White Matter were involved in all four cases, and hence may be considered biological substrates of BD in MS. Larger studies are needed to validate the utility of these findings.

RESUMO

BACKGROUND AND HYPOTHESIS: The current study investigated the extent to which changes in attentional control contribute to performance on a visual perceptual discrimination task, on a trial-by-trial basis in a transdiagnostic clinical sample. STUDY DESIGN: Participants with schizophrenia (SZ; N = 58), bipolar disorder (N = 42), major depression disorder (N = 51), and psychiatrically healthy controls (N = 92) completed a visual perception task in which stimuli appeared briefly. The design allowed us to estimate the lapse rate and the precision of perceptual representations of the stimuli. Electroencephalograms (EEG) were recorded to examine pre-stimulus activity in the alpha band (8-13 Hz), overall and in relation to behavior performance on the task. STUDY RESULTS: We found that the attention lapse rate was elevated in the SZ group compared with all other groups. We also observed group differences in pre-stimulus alpha activity, with control participants showing the highest levels of pre-stimulus alpha when averaging across trials. However, trial-by-trial analyses showed within-participant fluctuations in pre-stimulus alpha activity significantly predicted the likelihood of making an error, in all groups. Interestingly, our analysis demonstrated that aperiodic contributions to the EEG signal (which affect power estimates across frequency bands) serve as a significant predictor of behavior as well. CONCLUSIONS: These results confirm the elevated attention lapse rate that has been observed in SZ, validate pre-stimulus EEG markers of attentional control and their use as a predictor of behavior on a trial-by-trial basis, and suggest that aperiodic contributions to the EEG signal are an important target for further research in this area, in addition to alpha-band activity.

RESUMO

INTRODUCTION: Varicocele is the abnormal dilatation of the pampiniform plexus. It occurs in 15-20% of pre-adolescent/adult males. Varicocele diagnosis is important since it can induce testicular hypertrophy and fertility issues in adulthood. The objective of this study was to assess whether complications, including varicocele recurrence, depend on the vascular occlusion technique used -clipping + division vs. vascular sealer- in the laparoscopic Palomo technique used in our institution. MATERIALS AND METHODS: A longitudinal, prospective study was carried out from 2017 to 2021. Two therapeutic groups were created according to the vascular occlusion method used during laparoscopic varicocelectomy -clipping + division vs. vascular sealer. Patients were randomly allocated to the groups in a systematic alternating consecutive manner. Variables -age, varicocele grade according to the Dubin-Amelar classification, postoperative complications, follow-up, and varicocele recurrence- were analyzed according to the method employed. RESULTS: A total of 37 boys, with a mean age of 12 years (10-15 years) and a mean follow-up of 12 months, were studied. In 20 patients (54.1%), clipping + division was used, and in the remaining 17 (45.9%), the vascular sealer was employed. 24.3% had symptomatic Grade II varicocele and 75.7% had Grade III varicocele. 32.4% of the children had postoperative complications during follow-up. 29.7% of the patients had hydrocele following surgery -8 boys from the sealing group and 3 boys from the clipping group-, with 13.5% requiring re-intervention as a result of this. None of the patients had varicocele recurrence. CONCLUSIONS: The laparoscopic Palomo technique is safe and effective, with good results in pediatric patients and few postoperative complications, regardless of the vascular occlusion device used. In our study, no statistically significant differences regarding the use of clipping or vascular sealer in this laparoscopic technique were found. However, further studies with a larger sample size are required to find potential differences.


INTRODUCCION: El varicocele es la dilatación anormal del plexo pampiniforme. Puede afectar al 15-20% de los varones preadolescentes-adultos. La importancia de su diagnóstico radica en que puede inducir hipotrofia testicular y problemas de fertilidad en la etapa adulta. El objetivo de este estudio es evaluar si existe mayor índice de complicaciones, incluyendo la recurrencia del varicocele, dependiendo de la técnica de oclusión vascular utilizada: clip y sección o sellador vascular, en la técnica de Palomo laparoscópico en nuestro centro. MATERIAL Y METODOS: Estudio longitudinal prospectivo que se realiza de 2017 a 2021. Se crean dos grupos terapéuticos según el método de oclusión vascular utilizada durante la varicocelectomía laparoscópica: clip y sección o sellador vascular. Los pacientes son incluidos en un grupo mediante asignación sistemática consecutiva alternante. Se realiza el análisis de las variables: edad, grado de varicocele según la clasificación de Dubin-Amelar, complicaciones postquirúrgicas, seguimiento y recurrencia del varicocele, según el método empleado. RESULTADOS: Se intervinieron un total de 37 niños, con edad media de 12 años (10-15 años) y una media de seguimiento de 12 meses. En 20 pacientes (54,1%), se utilizó clip y sección, y en los 17 restantes (45,9%), sellador vascular. El 24,3% presentaba varicocele Grado II sintomático y el 75,7%, Grado III. El 32,4% de los niños presentó alguna complicación postquirúrgica durante el seguimiento. El 29,7% de los pacientes presentó hidrocele tras la intervención, perteneciendo 8 niños al grupo de sellado y 3 niños al de clipaje. El 13,5% de estos precisó reintervención por este motivo. Ningún paciente presentó recurrencia del varicocele. CONCLUSIONES: La técnica de Palomo laparoscópica es una técnica segura y efectiva que presenta buenos resultados en pacientes pediátricos, ya que presenta pocas complicaciones postquirúrgicas, independientemente del dispositivo de oclusión vascular que se utilice. En nuestro estudio, no se ha demostrado que existan diferencias estadísticamente significativas en cuanto al uso de clip o sellador vascular en esta técnica laparoscópica. No obstante, es preciso realizar más estudios con mayor tamaño muestral para hallar posibles diferencias.

RESUMO

BACKGROUND: Bipolar disorder is a broad diagnostic construct associated with significant phenotypic and genetic heterogeneity challenging progress in clinical practice and discovery research. Prospective studies of well-characterized patients and their family members have identified lithium responsive (LiR) and lithium non-responsive (LiNR) subtypes that hold promise for advancement. METHOD: In this narrative review, relevant observations from published longitudinal studies of well-characterized bipolar patients and their families spanning six decades are highlighted. DSM diagnoses based on SADS-L interviews were decided in blind consensus reviews by expert clinicians. Genetic, neurobiological, and psychosocial factors were investigated in subsets of well-characterized probands and adult relatives. Systematic maintenance trials of lithium, antipsychotics, and lamotrigine were carried out. Clinical profiles that included detailed histories of the clinical course, symptom sets and disorders segregating in families were documented. Offspring of LiR and LiNR families were repeatedly assessed up to 20 years using KSADS-PL format interviews and DSM diagnoses and sub-threshold symptoms were decided by expert clinicians in blind consensus reviews using all available clinical and research data. RESULTS: A characteristic clinical profile differentiated bipolar patients who responded to lithium stabilization from those who did not. The LiR subtype was characterized by a recurrent fully remitting course predominated by depressive episodes and a positive family history of episodic remitting mood disorders, and not schizophrenia. Response to lithium clustered in families and the characteristic clinical profile predicted lithium response, with the episodic remitting course being a strong correlate. There is accumulating evidence that genetic and neurobiological markers differ between LiR and LiNR subtypes. Further, offspring of bipolar parents subdivided by lithium response differed in developmental history, clinical antecedents and early course of mood disorders. Moreover, the nature of the emergent course bred true from parent to offspring, independent of the nature of emergent psychopathology. CONCLUSIONS: Bipolar disorders are heterogeneous and response to long-term lithium is associated with a familial subtype with characteristic course, treatment response, family history and likely pathogenesis. Incorporating distinctive clinical profiles that index valid bipolar subtypes into routine practice and research will improve patient outcomes and advance the development and translation of novel treatment targets to improve prevention and early intervention.

RESUMO

Bipolar disorder (BD) is a serious mental health condition that is clinically complex to monitor and manage. While best practice guidelines exist, they vary internationally lacking consensus. Indigenous peoples, including Maori in New Zealand, experience higher community rates of BD. While New Zealand practice guidelines recommend providing culturally responsive care to Maori, studies show that Maori do not receive best practice. This qualitative study aimed to share the evidence about patterns of health service use and Maori patient experiences with focus group participants involved in the design and delivery of BD services, to discuss and develop guidelines for best practice for Maori with BD and address areas of unmet need. Three focus groups were conducted with 22 participants involved in the delivery of services to Maori with BD across three sites. Willing participants were sent background information and three focus group questions framed to elicit priority solutions to improve clinical, structural and organisational features of mental health service delivery for Maori patients with BD and their whanau (family). The nominal group technique was used to synthesise responses, and then develop a prioritised list of proposed solutions. Results identified system-level changes required at the clinical, structural and organisational levels of healthcare. Findings further evidence the need for healthcare reform in New Zealand, to be responsive to Maori with BD.

RESUMO

(1) Background Cerebral revascularization is necessary to treat intracranial arterial stenosis caused by moyamoya disease, atherosclerosis, or large complex aneurysms. Although various donor vascular harvesting methods have been reported safe, there are no reports on the histological evaluation of donor vessels for each disease, despite the variety of diseases wherein vascular anastomosis is required. (2) Methods Pathological findings of the superficial temporal artery (STA), radial artery (RA), occipital artery (OA), and saphenous vein (SV) harvested at the institution were analyzed. Patients classified according to aneurysm, atherosclerosis, and moyamoya disease were assessed for pathological abnormalities, medical history, age, sex, smoking, and postoperative anastomosis patency. (3) Results There were 38 cases of atherosclerosis, 15 cases of moyamoya disease, and 30 cases of aneurysm in 98 donor vessels (mean age 57.2) taken after 2006. Of the 84 STA, 11 RA, 2 OA, and 1 SV arteries that were harvested, 71.4% had atherosclerosis, 11.2% had dissection, and 10.2% had inflammation. There was no significant difference in the proportion of pathological findings according to the disease. A history of hypertension is associated with atherosclerosis in donor vessels. (4) Conclusions This is the first study to histologically evaluate the pathological findings of donor vessels according to disease. The proportion of dissection findings indicative of vascular damage due to surgical manipulation was not statistically different between the different conditions.

RESUMO

BACKGROUND: Inflammation impairs cognitive function in healthy individuals and people with psychiatric disorders, such as bipolar disorder (BD). This effect may also impact emotion recognition, a fundamental element of social cognition. Our study aimed to investigate the relationships between pro-inflammatory cytokines and emotion recognition in euthymic BD patients and healthy controls (HCs). METHODS: We recruited forty-four euthymic BD patients and forty healthy controls (HCs) and measured their inflammatory markers, including high-sensitivity C-reactive protein (hs-CRP), interleukin-6 (IL-6), and TNF-α. We applied validated cognitive tasks, the Wisconsin Card-Sorting Test (WCST) and Continuous Performance Test (CPT), and a social cognitive task for emotion recognition, Diagnostic Analyses of Nonverbal Accuracy, Taiwanese Version (DANVA-2-TW). We analyzed the relationships between cytokines and cognition and then explored possible predictive factors of sadness recognition accuracy. RESULTS: Regarding pro-inflammatory cytokines, TNF-α was elevated in euthymic BD patients relative to HCs. In euthymic BD patients only, higher TNF-α levels were associated with lower accuracy of sadness recognition. Regression analysis revealed that TNF-α was an independent predictive factor of sadness recognition in patients with euthymic BD when neurocognition was controlled for. CONCLUSIONS: We demonstrated that enhanced inflammation, indicated by increased TNF-α, was an independent predictive factor of impaired sadness recognition in BD patients but not in HCs. Our findings suggested a direct influence of TNF-α on sadness recognition and indicated vulnerability to depression in euthymic BD patients with chronic inflammation.

RESUMO

The effectiveness of universal preventive approaches in reducing the incidence of affective/psychotic disorders is unclear. We therefore aimed to synthesise the available evidence from randomised controlled trials. For studies reporting change in prevalence, we simulated all possible scenarios for the proportion of individuals with the disorder at baseline and at follow-up to exclude them. We then combined these data with studies directly measuring incidence and conducted random effects meta-analysis with relative risk (RR) to estimate the incidence in the intervention group compared to the control group. Eighteen studies (k=21 samples) were included investigating the universal prevention of depression in 66,625 individuals. No studies were available investigating universal prevention on the incidence of bipolar/psychotic disorders. 63 % of simulated scenarios showed a significant preventive effect on reducing the incidence of depression (k=9 - 19, RR=0.75-0.94, 95 %CIs=0.55-0.87,0.93-1.15, p=0.007-0.246) but did not survive sensitivity analyses. There is some limited evidence for the effectiveness of universal interventions for reducing the incidence of depression but not for bipolar/psychotic disorders.

RESUMO

Bipolar affective disorder refers to a category of mood disorders characterized clinically by the presence of both manic or hypomanic episodes and depressive episodes. Lithium stands out as the primary pharmacological intervention for managing bipolar affective disorder. However, its therapeutic dosage closely approaches toxic levels. Toxic symptoms appear when the blood lithium concentration surpasses 1.4 mmol/L, typically giving rise to gastrointestinal and central nervous system reactions. Cardiac toxicity is rare but serious in cases of lithium poisoning. The study reports a case of a patient with bipolar affective disorder who reached a blood lithium concentration of 6.08 mmol/L after the patient took lithium carbonate sustained-release tablets beyond the prescribed dosage daily and concurrently using other mood stabilizers. This resulted in symptoms such as arrhythmia, shock, impaired consciousness, and coarse tremors. Following symptomatic supportive treatment, including blood dialysis, the patient's physical symptoms gradually improved. It is necessary for clinicians to strengthen the prevention and recognition of lithium poisoning.
