Sexual dysfunction is a common side effect of antidepressants, significantly impacting patients' quality of life and treatment adherence. This study investigates the relationship between sexual dysfunction and antidepressants by analyzing data from VigiBase™, the World Health Organization's global database of individual case safety reports. In this study, we examined, for the first time, reports related to sexual response—desire, arousal, and orgasm—by grouping appropriate side effect terms and calculated the reporting odds ratios (RORs) for various antidepressants. The findings of this study highlight a high disproportional reporting of sexual dysfunction, particularly with selective serotonin reuptake inhibitors and serotonin–norepinephrine reuptake inhibitors. In contrast, agents such as agomelatine, bupropion, and mirtazapine showed a lower association. Furthermore, we investigated the correlation between reporting odds ratios and the binding affinities of antidepressants to specific neurotransmitter receptors and transporters, unveiling significant relationships that provide insights into the pharmacodynamic pathways underlying these adverse effects. For instance, a positive correlation was observed between the serotonin transporter and side effects in the category desire: r (19) = 0.67, p = 0.001 These insights underscore the necessity for clinicians to consider sexual side effects when prescribing antidepressants and to monitor and address these issues to improve patient outcomes.

LEVONORGESTREL intrauterine contraceptives ,INTRAUTERINE contraceptives ,MENTAL illness ,MENTAL depression ,SUICIDE risk factors ,SYMPTOMS - Abstract
Levonorgestrel (LNG)-intrauterine devices (IUDs) are an effective method of contraception; however, there is growing evidence regarding potential psychiatric side effects such as depressive symptoms, anxiety, and suicidal thoughts. Therefore, we conducted this systematic review to summarise the psychiatric effects of using LNG-IUDs. We searched six databases (MEDLINE, Web of Science, Scopus, Science Direct, Cochrane Library, and PsycInfo), and we included all study designs. The included studies were extracted, quality assessed, and qualitatively summarised. Out of the screened studies, only 22 were finally included. While ten studies showed increased depressive symptoms, two studies showed reduced symptoms. Moreover, one study showed increased anxiety, another one reported an increased risk of suicide, four studies concluded no association with depressive symptoms, and four other studies showed uncertainty about a potential association but mentioned other psychiatric symptoms. Despite unreliable data, many studies report psychiatric symptoms associated with LNG-IUDs, predominantly depression. Gynaecologists, general practitioners, and psychiatrists should therefore be aware of these potential risks, especially depressive symptoms and suicidality. Counselling patients about these risks should be mandatory. Further studies should investigate the absolute risk of mental disorders associated with LNG-IUDs and other hormonal contraceptives. Many researchers are reporting adverse psychiatric events associated with levonorgestrel intrauterine devices (LNG-IUDs). Despite their effectiveness, a proper psychiatric assessment should be done before inserting LNG-IUDs. Proper counselling regarding the depressive symptoms and suicidality should be done by the treating obstetrician. Further studies should investigate the absolute risk of mental disorders associated with LNG-IUDs and other hormonal contraceptives. [ABSTRACT FROM AUTHOR]

DEPRESSION in adolescence ,SELF-injurious behavior ,FUNCTIONAL magnetic resonance imaging ,RESPONSE inhibition ,PREFRONTAL cortex - Abstract
Non-suicidal self-injury (NSSI), as a highly prevalent psychiatric symptom in adolescents and young adults, is defined as the deliberate destruction of body tissue without suicidal intent. Impulsivity and dysfunctional response inhibition have been suggested to play a central role in adolescents' vulnerability to self-harm. To investigate the potentially distinct neurobiology of NSSI, we used a well-established Go/No Go task in which activation of the inferior frontal gyrus (IFG) and dorsal anterior cingulate cortex (dACC) is interpreted as a neural correlate of processing failed response inhibition. Task-based functional magnetic resonance imaging data were obtained from 14 adolescents with a diagnosis of major depression and a history of NSSI (MD-NSSI), 13 depressed adolescents without NSSI (MD-only), and 14 healthy controls (HC). In line with hypotheses of dysfunctional response inhibition, we observed increased rates of commission errors in MD-NSSI along with significantly reduced error-related activations of the dACC and IFG. Intact response inhibition, as reflected by low commission error rates not different from HC, was observed in MD-only, along with increased activation of the error-processing network. Our findings support the hypothesis of a distinct neurobiological signature of NSSI. Further research on biomarkers of NSSI could focus on behavioral and neural correlates of failed response inhibition. [ABSTRACT FROM AUTHOR]

The levonorgestrel-releasing intrauterine system (LNG-IUS) is used as hormonal contraception by millions of women worldwide. It is considered as a safe device with low rates of systemic adverse drug reactions (ADRs). However, an emerging evidence suggest mood changes as ADRs. Whereas most of these studies report psychiatric ADRs after the first implantation of the LNG-IUS, it has to be considered that these may also occur after replacement, even when psychiatric symptoms were not evident at the time of the initial insertion. A potential explanation for the development of psychiatric ADRs in subsequent LNG-IUS may rely on fluctuations of sex hormones throughout the female life cycle with changing windows of vulnerabilities for developing mood disorders. Thus, the reliable contraception for women remains a continual challenge. We present the case of a 41-year-old woman that used the LNG-IUS (Mirena®) for contraception over 5 years without any complaints. Within the first weeks after insertion of the second LNG-IUS, she developed a depressive syndrome and anxieties. An extensive somatic, including gynecological examination revealed no pathological findings and a mental disorder was suggested. Due to the patient´s request and the recommendation of her psychiatrist, the device was removed and led to a remission of her mental complaints up to a 6- and 12-months follow-up. Beyond the mood changes considerably affecting her quality of life, the patient raised the concerns that she has never been informed about potential ADRs on mental health and her remarks regarding the potential association between psychiatric symptoms and the LNG-IUS were considered as groundless. With this case, we strengthen previous observations regarding mood changes under LNG-IUS. Moreover, we illustrate that psychiatric symptoms may also occur as ADRs during the subsequent insertion. Thus, we emphasize that psychiatric symptoms have to be clearly communicated as ADRs to patients with LNG-IUS within a written informed consent and should be routinely examined by gynecologists.

BACKGROUND: A set of enduring conditions have been reported in the literature involving persistent sexual dysfunction after discontinuation of serotonin reuptake inhibiting antidepressants, 5 alpha-reductase inhibitors and isotretinoin. OBJECTIVE: To develop diagnostic criteria for post-SSRI sexual dysfunction (PSSD), persistent genital arousal disorder (PGAD) following serotonin reuptake inhibitors, post-finasteride syndrome (PFS) and post-retinoid sexual dysfunction (PRSD). METHODS: The original draft was designed using data from two published case series (Hogan et al., 2014 and Healy et al., 2018), which represent the largest public collections of data on these enduring conditions. It was further developed with the involvement of a multidisciplinary panel of experts. RESULTS: A set of criteria were agreed upon for each of the above conditions. Features of PSSD, PFS and PRSD commonly include decreased genital and orgasmic sensation, decreased sexual desire and erectile dysfunction. Ancillary non-sexual symptoms vary depending on the specific condition but can include emotional blunting and cognitive impairment. PGAD presents with an almost mirror image of unwanted sensations of genital arousal or irritability in the absence of sexual desire. A new term, post-SSRI asexuality, is introduced to describe a dampening of sexual interest and pleasure resulting from a pre-natal or pre-teen exposure to a serotonin reuptake inhibitor. CONCLUSIONS: These criteria will help in both clinical and research settings. As with all criteria, they will likely need modification in the light of developments. [ABSTRACT FROM AUTHOR]

Background: Spinal Muscular Atrophy (SMA) is a severe neurodegenerative disease, characterized by progressive muscle weakness and atrophy. The approval of the antisense oligonucleotide (ASO) nusinersen now provides an effective pharmacological approach with the potential to slow down or stop disease progression with a potentially major impact on patients' well-being. Objective: This study evaluates quality of life (QoL) in pediatric and adult patients over the course of therapy with nusinersen. Methods: Twenty-six SMA patients treated with nusinersen were evaluated regarding global QoL (gQoL), health-related QoL (HRQoL) and depressiveness. Assessments were conducted three times over the first 6 months of treatment. Applied were different questionnaires: the Anamnestic Comparative Self-Assessment (ACSA) for gQoL, the Short Form-36 Health Survey (SF-36) for HRQoL in adult patients and the ALS Depression Inventory 12 Items (ADI-12) for depressiveness. The sample was matched with 22 healthy controls. Results: Despite severe physical restrictions, patients reported high levels of QoL and low levels of depressiveness at study entry. Early disease onset and low levels of physical functioning were associated with better gQoL and lower levels of depressiveness. A significant decrease of gQoL in patients was evident over the course of the study. Still, adult patients reported a significant increase in perceived health. Conclusions: Our study provides first insight that SMA patients experience a gQoL superior to healthy controls at start of therapy. This might indicate patients' high hopes and expectations toward treatment. gQoL returns to a level similar to that of healthy controls over the course of therapy. [ABSTRACT FROM AUTHOR]

One of the most common adverse events (AEs) occurring during treatment with aromatase inhibitors (AIs) is musculoskeletal pain. The aim of our study was to analyze the influence of preexisting muscle/limb pain and joint pain on the development of AI‐induced musculoskeletal AEs. Women eligible for upfront adjuvant endocrine therapy with letrozole were included in the PreFace study, a multicenter phase IV trial. During the first treatment year, they were asked to record musculoskeletal AEs monthly by answering questions regarding pain symptoms and rating the pain intensity on a numeric rating scale from 0 (no pain) to 10 (very strong pain). Pain values were compared using nonparametric statistical tests. Overall, 1,416 patients were evaluable. The average pain value over all time points in women with preexisting muscle/limb pain was 4.3 (median 4.3); in those without preexisting pain, it was 2.0 (median 1.7). In patients without preexisting muscle/limb pain, pain levels increased relatively strongly within the first 6 months (mean increase +0.9, p < 0.00001) in comparison with those with preexisting pain (mean increase +0.3, p < 0.001), resulting in a statistically significant difference (p < 0.00001) between the two groups. The development of joint pain was similar in the two groups. Women without preexisting muscle/limb pain or joint pain have the greatest increase in pain after the start of adjuvant AI therapy. Women with preexisting pain have significantly higher pain values. The main increase in pain values takes place during the first 6 months of treatment. What's new? A standard treatment for breast cancer is aromatase inhibitors (AIs), but common adverse events including musculoskeletal pain can cause early discontinuation. This study analyzed the influence of preexisting muscle/limb pain and joint pain on the development of AI‐induced musculoskeletal adverse events. Women without preexisting muscle/limb or joint pain have the greatest increase in pain after starting adjuvant AI therapy. Women with preexisting pain have higher pain scores, but a smaller increase in pain in comparison. The main increase in pain scores takes place in the first 6 months of endocrine treatment, calling for greater physician attention during this time window. [ABSTRACT FROM AUTHOR]

Borderline Personality Disorder (BPD) is clinically characterized by emotional instability, interpersonal disturbances and dysfunctional behavior such as non-suicidal self-injury (NSSI). During NSSI, patients with BPD typically report analgesic or hypoalgesic phenomena, and pain perception and pain processing in BPD have been repeatedly investigated. Most of the studies so far focused on affective-motivational and cognitive-evaluative neural components of pain within categorial study designs. By contrast, rather basic somatosensory aspects such as neural intensity-encoding of somatosensory stimuli were not examined in further details. Thus, we investigated patients with BPD and healthy controls (HC) by functional magnetic resonance imaging (fMRI) during an unpleasant sensory stimulation task with parametrically increasing stimulus intensities. 15 females diagnosed with BPD and 15 HCs were investigated with fMRI during four individually adjusted levels of electrical stimulus intensities. Ratings of stimulus intensity were assessed by button presses during fMRI. fMRI-data were analyzed by analyses of variances (ANOVA) at a statistical threshold of p < 0.05 FWE-corrected on cluster level. Subjective ratings of stimulus intensities were alike between BPD and HC, and intensity levels identified with equal accuracy. Significant intensity-encoding neural activations were observed within the primary and secondary somtasensory cortex, the posterior insula, the posterior midcingulate cortex (pMCC) and the supplementary motor area (SMA) in both, HC and BPD. Notably, there were no significant between-groups differences in intensity-encoding neural activations, even at lowered significance thresholds. Present results suggest a similar neural somatosensory stimulus intensity encoding in BPD as previously observed on a behavioral level. The alterations in neural affective-motivational or cognitive-evaluative components reported so far may be restricted to pain rather than unpleasant stimulus processing and were absent in our study.

ANTIDEPRESSANTS ,PLACEBOS ,FUNCTIONAL magnetic resonance imaging - Abstract
We recently investigated the effects of the noradrenergic antidepressant reboxetine and the antipsychotic amisulpride compared to placebo on neural correlates of primary reinforcers by visual erotic stimulation in healthy subjects. Whereas, amisulpride left subjective sexual functions and corresponding neural activations unimpaired, attenuated neural activations were observed under reboxetine within the nucleus accumbens (Nacc) along with diminished behavioral sexual functioning. However, a global dampening of the reward system under reboxetine seemed not intuitive considering the complementary role of the noradrenergic to the dopamine system in reward-related learning mediated by prediction error processing. We therefore investigated the sample of 17 healthy males in a mean age of 23.8 years again by functional magnetic resonance imaging (fMRI), to explore the noradrenergic effects on neural reward prediction error signaling. Participants took reboxetine (4 mg/d), amisulpride (200 mg/d), and placebo each for 7 days within a randomized, double-blind, within-subject cross-over design. During fMRI, we used an established monetary incentive task to assess neural reward expectation and prediction error signals within the bilateral Nacc using an independent anatomical mask for a region of interest (ROI) analysis. Activations within the same ROI were also assessed for the erotic picture paradigm. We confirmed our previous results from the whole brain analysis for the selected ROI by significant (p < 0.05 FWE-corrected) attenuated activations within the Nacc during visual sexual stimulation under reboxetine compared to placebo. However, activations in the Nacc concerning prediction error processing and monetary reward expectation were unimpaired under reboxetine compared to placebo, along with unimpaired reaction times in the reward task. For both tasks, neural activations and behavioral processing were not altered by amisulpride compared to placebo. The observed attenuated neural activations within the Nacc during visual erotic stimulation along with unimpaired neural prediction error and monetary reward expectation processing provide evidence for a differential modulation of the neural reward system by the noradrenergic agent reboxetine depending on the presence of primary reinforcers such as erotic stimuli in contrast to secondary such as monetary rewards.

Background: Various psychiatric populations are currently investigated with resting state fMRI, with the aim of individualizing diagnostics and treatment options and improving treatment outcomes. Many of these studies are conducted in large naturalistic samples, providing rich insights regarding disease-related neural alterations, but with the common psychopharmacological medication limiting interpretations of the results. We therefore investigated the effects of common noradrenergic and anti-dopaminergic medications on local and global resting state activity (rs-activity) in healthy volunteers to further the understanding of the respective effects independent from disease-related alterations. Methods: Within a randomized, double-blind, placebo-controlled crossover design, we investigated 19 healthy male subjects by resting state fMRI after the intake of reboxetine (4 mg/d), amisulpride (200 mg/d), and placebo for 7 days each. Treatmentrelated differences in local and global rs-activity were measured by the fractional amplitude of low frequency fluctuations (fALFF) and resting state functional connectivity (rs-FC). Results: fALFF revealed alterations of local rs-activity within regions of the core noradrenergic pathway, including the locus coeruleus under reboxetine, correlated with its plasma levels. Moreover, reboxetine led to increased rs-FC between regions within this pathway, i.e. the locus coeruleus, tectum, thalamus, and amygdala. Amisulpride modulated local rs-activity of regions within the dopaminergic pathway, with the altered signal in the putamen correlating with amisulpride plasma levels. Correspondingly, amisulpride increased rs-FC between regions of the dopaminergic pathway comprising the substantia nigra and putamen. Conclusion: Our data provide evidence of how psychopharmacological agents alter local and global rs-activity within the respective neuroanatomical pathways in healthy subjects, which may help with interpreting data in psychiatric populations.

While antidepressants are supposed to exert similar effects on mood and drive via various mechanisms of action, diverging effects are observed regarding side-effects and accordingly on neural correlates of motivation, emotion, reward and salient stimuli processing as a function of the drugs impact on neurotransmission. In the context of erotic stimulation, a unidirectional modulation of attentional functioning despite opposite effects on sexual arousal has been suggested for the selective serotonin reuptake-inhibitor (SSRI) paroxetine and the selective dopamine and noradrenaline reuptake-inhibitor (SDNRI) bupropion. To further elucidate the effects of antidepressant-related alterations of neural attention networks, we investigated 18 healthy males under subchronic administration (7 d) of paroxetine (20 mg), bupropion (150 mg) and placebo within a randomized placebo-controlled cross-over double-blind functional magnetic resonance imaging (fMRI) design during an established preceding attention task. Neuropsychological effects beyond the fMRI-paradigm were assessed by measuring alertness and divided attention. Comparing preceding attention periods of salient vs. neutral pictures, we revealed congruent effects of both drugs vs. placebo within the anterior midcingulate cortex, dorsolateral prefrontal cortex, anterior prefrontal cortex, superior temporal gyrus, anterior insula and the thalamus. Relatively decreased activation in this network was paralleled by slower reaction times in the divided attention task in both verum conditions compared to placebo. Our results suggest similar effects of antidepressant treatments on behavioural and neural attentional functioning by diverging neurochemical pathways. Concurrent alterations of brain regions within a fronto-parietal and cingulo-opercular attention network for top-down control could point to basic neural mechanisms of antidepressant action irrespective of receptor profiles.

Intoxications with alcohol may lead to death depending on (maximum) blood alcohol concentration (BAC) and accompanying factors such as liver function, tolerance, and comedication. Death may occur due to ethanol-induced respiratory depression and/or aspiration of gastric content (due to an impaired gag reflex); thus, securing of the airway and ventilation is occasionally necessary. A case of a 58-year-old female patient with depression who demonstrated a very high BAC of 8.68 gm/L (0.868%) following ingestion of large amounts of alcohol with suicidal intent is presented. Intubation and ventilation were life-saving, and the patient did not develop any physical or consequential damage. As the patient had not regularly used alcohol or any other psychotropic agent, tolerance could be ruled out. This case emphasizes the necessity of rapid securing of the airway in patients with alcohol intoxication and respiratory depression and, furthermore, illustrates the large interindividual differences regarding ethanol susceptibility.

PSILOCYBIN ,MENTAL depression ,PSYCHIATRIC treatment ,HALLUCINOGENIC drugs - Abstract
There has recently been a renewal of interest in psychedelic research on the use of psilocybin in psychiatric treatment and, in particular, for the treatment of major depressive disorder (MDD). Several state-of-the-art studies have provided new insight into the mechanisms of action of psilocybin and its therapeutic potential. Nevertheless, many questions remain unanswered. With this review, we provide an overview of the current state of research on the potential mechanisms of psilocybin, its antidepressant potential, and the associated risks and adverse effects, to provide an update on a controversial topic discussed in psychopharmacology. A database search was conducted in Medline including articles on psilocybin over the period of the last 20 years. Despite the promising progress in understanding the mechanisms of psilocybin, the exact antidepressive mechanism and the role of the psychedelic experience remain elusive. The studies included in this review found high treatment effect sizes for psilocybin as an antidepressant. However, the results must be regarded as preliminary due to several limitations. Although the current studies observed no severe adverse events, several questions regarding safety and utility remain and must be subject of future research. [ABSTRACT FROM AUTHOR]

Various studies suggested alterations in pain perception in psychiatric disorders, such as borderline personality disorder (BPD) and major depression (MD). We previously investigated affective components of pain perception in BPD compared to healthy controls (HC) by increasing aversive stimulus intensities using repetitive peripheral magnetic stimulation (rPMS) and observed alterations in emotional rather than somatosensory components in BPD. However, conclusions on disorder specific alterations in these components of pain perception are often limited due to comorbid depression and medication in BPD. Here, we compared 10 patients with BPD and comorbid MD, 12 patients with MD without BPD, and 12 HC. We applied unpleasant somatosensory stimuli with increasing intensities by rPMS and assessed pain threshold (PT), cutaneous sensation, emotional valence, and arousal by a Self-Assessments Manikins scale. PTs in BPD were significantly higher compared to HC. The somatosensory discrimination of stimulus intensities did not differ between groups. Though elevated rPMS intensities led to increased subjective aversion and arousal in MD and HC, these emotional responses among intensity levels remained unchanged in BPD. Our data give further evidence for disorder-specific alterations in emotional components of pain perception in BPD with an absent emotional modulation among varying aversive intensity levels.

FUNCTIONAL magnetic resonance imaging , *HUMAN behavior , *MEN , *HUMAN anatomy , *SEXUAL dysfunction , *HUMAN sexuality - Abstract
Human sexual behavior is mediated by a complex interplay of cerebral and spinal centers, as well as hormonal, peripheral, and autonomic functions. Neuroimaging studies identified central neural signatures of human sexual responses comprising neural emotional, motivational, autonomic, and cognitive components. However, empirical evidence regarding the neuromodulation of these neural signatures of human sexual responses was scarce for decades. Pharmacological functional magnetic resonance imaging (fMRI) provides a valuable tool to examine the interaction between neuromodulator systems and functional network anatomy relevant for human sexual behavior. In addition, this approach enables the examination of potential neural mechanisms regarding treatment-related sexual dysfunction under psychopharmacological agents. In this article, we introduce common neurobiological concepts regarding cerebral sexual responses based on neuroimaging findings and we discuss challenges and findings regarding investigating the neuromodulation of neural sexual stimulus processing. In particular, we summarize findings from our research program investigating how neural correlates of sexual stimulus processing are modulated by serotonergic, dopaminergic, and noradrenergic antidepressant medication in healthy males.

Background: Impaired sexual function is increasingly recognized as a side effect of psychopharmacological treatment. However, underlying mechanisms of action of the different drugs on sexual processing are still to be explored. Using functional magnetic resonance imaging, we previously investigated effects of serotonergic (paroxetine) and dopaminergic (bupropion) antidepressants on sexual functioning (Abler et al., 2011). Here, we studied the impact of noradrenergic and antidopaminergic medication on neural correlates of visual sexual stimulation in a new sample of subjects. Methods: Nineteen healthy heterosexual males (mean age 24 years, SD 3.1) under subchronic intake (7 days) of the noradrenergic agent reboxetine (4mg/d), the antidopaminergic agent amisulpride (200mg/d), and placebo were included and studied with functional magnetic resonance imaging within a randomized, double-blind, placebo-controlled, within-subjects design during an established erotic video-clip task. Subjective sexual functioning was assessed using the Massachusetts General Hospital-Sexual Functioning Questionnaire. Results: Relative to placebo, subjective sexual functioning was attenuated under reboxetine along with diminished neural activations within the caudate nucleus. Altered neural activations correlated with decreased sexual interest. Under amisulpride, neural activations and subjective sexual functioning remained unchanged. Conclusions: In line with previous interpretations of the role of the caudate nucleus in the context of primary reward processing, attenuated caudate activation may reflect detrimental effects on motivational aspects of erotic stimulus processing under noradrenergic agents.

Neuroinflammation has been connected to the pathophysiology of major depressive disorder (MDD) and neurochemical biomarkers of glial pathology could aid the diagnosis and might support patient stratification and monitoring in clinical trials. Our study aimed to determine the utility of glial fibrillary acidic protein (GFAP), a marker of astrocyte activation, for the differential diagnosis and monitoring of MDD. Employing Simoa technology we measured levels of GFAP in prospectively collected serum samples from 81 age-matched patients with MDD, schizophrenia (SZ), bipolar disorder (BP), and healthy controls (HC). Highest GFAP levels were determined for MDD. At a cut-off of 130 pg/ml, MDD could be discriminated with 87% sensitivity from SZ and BP (specificity 70%) and from HC (specificity 56%). GFAP levels increased with age (r = 0.5236, p = 0.0002) and with MDD severity quantified based on the Montgomery-Åsberg Depression Rating Scale (r = 0.4308, p = 0.0221). Neurofilament light chain serum levels were not different in the diagnostic groups and not associated with GFAP levels (r = 0.0911, p = 0.576) pointing to an independence of astrocyte activation on neurodegeneration. Our study provides first evidence that serum GFAP levels could improve the differential diagnosis of MDD and that depression severity could be objectively quantified using serum GFAP levels. Furthermore, serum GFAP might represent a marker to monitor astroglial pathology in the course of MDD. [ABSTRACT FROM AUTHOR]
