Effects of transcranial magnetic stimulation on cocaine addiction: A systematic review of randomized controlled trials.

OBJECTIVE: While pharmacological strategies appear to be ineffective in treating long-term addiction, repetitive transcranial magnetic stimulation (rTMS) is emerging as a promising new tool for the attenuation of craving among multiple substance dependent populations. METHOD: A systematic review of randomized controlled trials (RCTs) was conducted on the efficacy and tolerability of rTMS in treating cocaine use disorder (CUD). Relevant papers published in English through November 30th 2022 were identified, searching the electronic databases MEDLINE, Embase, PsycINFO and the Cochrane Library. RESULTS: Eight studies matched inclusion criteria. The best findings were reported by the RCTs conducted at high-frequency (≥5 Hz) multiple sessions of rTMS delivered over the left dorsolateral prefrontal cortex (DLPFC): a significant decrease in self-reported cue-induced cocaine craving and lower cocaine craving scores and a considerable amelioration in the tendency to act rashly under extreme negative emotions (impulsivity) were found in the active group compared to controls. CONCLUSION: Although still scant and heterogeneous, the strongest evidence so far on the use of rTMS on individuals with CUD support the high frequency stimulation over the left DLPFC as a well tolerated treatment of cocaine craving and impulsivity.

Transition to retirement impact on risk of depression and suicidality: results from a longitudinal analysis of the Survey of Health, Ageing and Retirement in Europe (SHARE).

AIMS: Depression is among the main contributors to older adults' mental health burden. Retirement, one of the major life transitions, has been claimed to influence mental health substantially. Following up on a previous meta-analysis, the study aims to assess from a longitudinal perspective short- and long-term impacts of transitioning to retirement on depression risk and suicidality in older adults across Europe. METHODS: We conducted a longitudinal study using data from the Survey of Health, Ageing and Retirement in Europe (SHARE), collected between 2004 and 2020 in 27 European countries plus Israel. To estimate relative risks (RR) and 95% confidence intervals (95% CIs) for depression and suicidality at seven time intervals before and after retirement, we fitted adjusted generalized estimating equation models for repeated measures. RESULTS: We included 8,998 individuals employed at baseline and retired at follow-up (median follow-up time: 9 years; maximum: 16 years). Compared to the year of retirement, the risk of depression was 11% lower in the following year (RR 0.89; 95% CI 0.81-0.99), 9% lower after 2 years (RR 0.91; 95% CI 0.82-1.00) and after 3 years (RR 0.91; 95% CI 0.81-1.01). Significant estimates remained among females, married individuals, those with an intermediate or higher level of education, former manual workers and those who retired at or before their country's median retirement age. A significant increase in depressive symptoms emerged from the tenth year after retirement among former non-manual workers (RR 1.21; 95% CI 1.05-1.40) and late retirees (RR 1.37; 95% CI 1.16-1.63). No heterogeneity emerged among strata. As for suicidality, we reported an increase in risk only 5 years or more after retirement, namely +30% 5-9 years after retirement (RR 1.30; 95% CI 1.04-1.64) and +47% 10 or more years after retirement (RR 1.47; 95% CI 1.09-1.98). Sensitivity analyses excluding subjects who reported a diagnosis of depression over the study period and those retirees who declared to receive a disability pension confirmed the results obtained in the overall analysis. CONCLUSIONS: Longitudinal adjusted data suggest an independent effect of retiring associated with a reduction in depression and suicidality risk in the short run, with its effect decreasing in the long run. Such trends are particularly evident among selected subgroups of elderly populations. If greater flexibility in pensionable age may help prevent depression late in life, the transition to retirement is to be accompanied by targeted health promotion interventions. In an ageing society, welfare policies should be evaluated, considering their long-term impact on mental health.

Hyper/neuroinflammation in COVID-19 and suicide etiopathogenesis: Hypothesis for a nefarious collision?

Accumulating scientific and clinical evidence highlighted pathological hyperinflammation as a cardinal feature of SARS-CoV-2 infection and acute COVID-19 disease. With the emergence of long COVID-19 syndrome, several chronic health consequences, including neuropsychiatric sequelae, have gained attention from the public and medical communities. Since inflammatory mediators have also been accredited as putative biomarkers of suicidal ideations and behaviors, hyper- and neuroinflammation might share some colliding points, overlapping and being interconnected in the context of COVID-19. This review aims to provide a summary of current knowledge on the molecular and cellular mechanisms of COVID-19-associated hyper/neuroinflammation with focus on their relevance to the inflammatory hypothesis of suicide development. Subsequently, strategies to alleviate COVID-19 hyper/neuroinflammation by immunomodulatory agents (many of which at experimental stages) as well as psychopharmacologic/psychotherapeutic approaches are also mentioned. While suicide risk in COVID-19 survivors - until now little known - needs further analysis through longitudinal studies, current observations and mechanistic postulates warrant additional attention to this possibly emerging mental health concern.

Does retirement trigger depressive symptoms? A systematic review and meta-analysis.

AIMS: Retirement is a major life transition that may improve or worsen mental health, including depression. Existing studies provide contradictory results. We conducted a systematic review with meta-analysis to quantitatively pool available evidence on the association of retirement and depressive symptoms. METHODS: We applied PRISMA guidelines to conduct a systematic review and meta-analysis to retrieve, quantitatively pool and critically evaluate the association between retirement and both incident and prevalent depression and to understand better the potential role of individual and contextual-level determinants. Relevant original studies were identified by searching PubMed, Embase, PsycINFO and the Cochrane Library, through 4 March 2021. Subgroup and sensitivity meta-analyses were conducted by gender, study design (longitudinal v. cross-sectional studies), study quality score (QS) and considering studies using validated scales to diagnose depression. Heterogeneity between studies was evaluated with I2 statistics. RESULTS: Forty-one original studies met our a priori defined inclusion criteria. Meta-analysis on more than half a million subjects (n = 557 111) from 60 datasets suggested a protective effect of retirement on the risk of depression [effect size (ES) = 0.83, 95% confidence interval (CI) = 0.74-0.93], although with high statistical heterogeneity between risk estimates (χ2 = 895.19, df = 59, I2 = 93.41%, p-value < 0.0001). Funnel plot asymmetry and trim and fill method suggested a minor potential publication bias. Results were consistent, confirm their robustness and suggest stronger protective effects when progressively restricting the included studies based on quality criteria: (i) studies with the highest QS [55 datasets, 407 086 subjects, ES = 0.81, 95% CI = 0.71-0.91], (ii) studies with a high QS and using validated assessment tools to diagnose depression (44 datasets, 239 453 subjects, ES = 0.76, 95% CI = 0.65-0.88) and (iii) studies of high quality, using a validated tool and with a longitudinal design (24 datasets, 162 004 subjects, ES = 0.76, 95% CI = 0.64-0.90). We observed a progressive reduction in funnel plot asymmetry. About gender, no statistically significant difference was found (females ES = 0.79, 95% CI = 0.61-1.02 v. men ES = 0.87, 95% CI = 0.68-1.11). CONCLUSIONS: Pooled data suggested that retirement reduces by nearly 20% the risk of depression; such estimates got stronger when limiting the analysis to longitudinal and high-quality studies, even if results are affected by high heterogeneity.As retirement seems to have an independent and protective effect on mental health and depressive symptoms, greater flexibility in retirement timing should be granted to older workers to reduce their mental burden and avoid the development of severe depression. Retirement may also be identified as a target moment for preventive interventions, particularly primary and secondary prevention, to promote health and wellbeing in older ages, boosting the observed impact.

Updates in treating comorbid bipolar disorder and obsessive-compulsive disorder: A systematic review.

BACKGROUND: In the last five years, the debate around the comorbidity between bipolar disorder (BD) and obsessive-compulsive disorder (OCD) has flourished within the international psychiatric community and several studies have been published on therapeutic strategies. METHODS: An update of our previous systematic review was conducted on clinical management of comorbid BD-OCD patients. Relevant papers published from July 1st 2013 to September 30th 2018 were identified searching the electronic databases MEDLINE, Embase, PsycINFO and the Cochrane Library. RESULTS: Fifteen studies were included. In all selected studies BD-OCD patients received mood stabilizers, alone or with second-generation antipsychotics (SGAs). Aripiprazole augmentation demonstrated to be effective as maintenance therapy and for treating obsessive-compulsive symptoms during manic episodes (40% of the studies, 6/15). Addition of antidepressants to mood stabilizers led to clinical remission of both conditions in only one case report. LIMITATIONS: Almost 50% of the selected studies are case reports. Enrolment of subjects mainly from outpatient specialty units might have introduced selection bias and limited community-wide generalizability. CONCLUSIONS: Mood stabilization should be the primary goal in treating BD-OCD patients. Aripiprazole augmentation to lithium carbonate seemed to be the best option in treatment-resistance comorbid patients. Addition of SRIs may be needed only in a minority of BD patients with refractory OCD.

Aripiprazole augmentation in treating comorbid bipolar disorder and obsessive-compulsive disorder: A systematic review.

BACKGROUND: Apparent comorbidity between bipolar disorder (BD) and obsessive-compulsive disorder (OCD) is a common condition in psychiatry, but treatment of BD-OCD remains a clinical challenge. Although serotonin reuptake inhibitors (SRIs) are the first line treatment for OCD, they can induce mood instability in BD. An optimal treatment approach remains to be defined. METHODS: A systematic review was conducted on aripiprazole augmentation in treating comorbid BD-OCD patients. Relevant papers published through August 31st 2018 were identified searching the electronic databases MEDLINE, Embase, PsycINFO and the Cochrane Library. RESULTS: Aripiprazole augmentation to mood stabilizers (lithium carbonate, valproate), even at low doses (10-15 mg/day), helped to achieve significant remission in affective and obsessive-compulsive symptoms. Aripiprazole was generally safe and well tolerated. LIMITATIONS: Most studies are case reports. Enrolment of subjects mainly from outpatient specialty units might have introduced selection bias and limited community-wide generalizability. CONCLUSIONS: Keeping in mind scantiness and heterogeneity of the available literature, the best interpretation of the available evidence appears to be that aripiprazole augmentation to mood stabilizers, even at low doses, is effective in BD-OCD patients.

Safety and efficacy of lithium in children and adolescents: A systematic review in bipolar illness.

INTRODUCTION: Many clinicians are reluctant to use traditional mood-stabilizing agents, especially lithium, in children and adolescents. This review examined the evidence for lithium's safety and efficacy in this population. METHODS: A systematic review was conducted on the use of lithium in children and adolescents with bipolar disorder (BD). Relevant papers published through June 30th 2018 were identified searching the electronic databases MEDLINE, Embase, PsycINFO and the Cochrane Library. RESULTS: 30 articles met inclusion criteria, including 12 randomized controlled trials (RCTs). Findings from RCTs demonstrate efficacy for acute mania in up to 50% of patients, and evidence of long-term maintenance efficacy. Lithium was generally safe, at least in the short term, with most common side effects being gastrointestinal, polyuria, or headache. Only a minority of patients experienced hypothyroidism. No cases of acute kidney injury or chronic kidney disease were reported. CONCLUSIONS: Though the available literature is mostly short-term, there is evidence that lithium monotherapy is reasonably safe and effective in children and adolescents, specifically for acute mania and for prevention of mood episodes.

Course of illness in comorbid bipolar disorder and obsessive-compulsive disorder patients.

Psychiatric comorbidity is extremely common. One of the most common and difficult to manage comorbid conditions is the co-occurrence of bipolar disorder (BD) and obsessive compulsive disorder (OCD). We updated our recent systematic review searching the electronic databases MEDLINE, Embase, and PsycINFO to investigate course of illness in BD-OCD patients. We identified a total of 13 relevant papers which found that the majority of comorbid OCD cases appeared to be related to mood episodes. OC symptoms in comorbid patients appeared more often during depressive episodes, and comorbid BD and OCD cycled together, with OC symptoms often remitting during manic/hypomanic episodes.

Clinical management of perinatal anxiety disorders: A systematic review.

BACKGROUND: In the last few decades, there has been a growing interest in anxiety disorders (AnxD) in the perinatal period. Although AnxD are diagnosed in 4-39% of pregnant women and in up to 16% of women after delivery, evidence on their clinical management is limited. METHODS: A systematic review was conducted on pharmacological and non-pharmacological treatment of AnxD in the perinatal period. Relevant papers published from January 1st 2015 were identified searching the electronic databases MEDLINE, Embase, PsycINFO and the Cochrane Library. RESULTS: 18 articles met inclusion criteria. Selected studies supported the use of cognitive-behavioural therapy (CBT) for obsessive-compulsive disorder (OCD), panic disorder (PD) and specific phobia both in pregnancy and postpartum. Selective serotonin reuptake inhibitors (SSRIs) led to significant OCD and PD improvement both in pregnancy and postpartum with no side effects for the babies. In the largest clinical sample to date, 65% of postpartum patients who entered the open-label trial of fluvoxamine (up to 300mg/day) experienced a 30% or greater decrease in the total score of the Yale-Brown Obsessive-Compulsive Scale (Y-BOCS). During pregnancy, SSRIs and tricyclic antidepressants (TCAs) led to remission of panic symptoms and healthy outcomes for the babies. LIMITATIONS: Study design, mostly case reports, and enrolment of subjects mainly from outpatient specialty units might have limited community-wide generalisability. CONCLUSIONS: Keeping in mind the scantiness and heterogeneity of the available literature, the best interpretation of the available evidence appears to be that CBT should be the first treatment offered to pregnant and breastfeeding women with AnxD. However SSRIs can represent a first line treatment strategy, and not exclusively in cases where AnxD is refractory to CBT.

The prevalence and predictors of comorbid bipolar disorder and obsessive-compulsive disorder: A systematic review and meta-analysis.

BACKGROUND: Although some authors have recently investigated the co-occurrence of anxiety and bipolar disorders, the topic remains insufficiently studied. Defining the prevalence and predictors of BD-OCD comorbidity has important nosological, clinical and therapeutic implications. METHODS: A systematic review and meta-analysis was conducted on the prevalence and predictors of comorbid BD-OCD. Relevant papers published through March 30th, 2015 were identified searching the electronic databases MEDLINE, Embase, PsycINFO and the Cochrane Library. RESULTS: 46 articles met inclusion criteria. The pooled prevalence of OCD in BD was 17.0% (95% CI 12.7-22.4%), which was comparable to the results reported by the pooled prevalence of BD in OCD (18.35%, 95% CI 13.2-24.8%). With regard to OCD-BD predictors, a higher mean age predicted a lower prevalence of OCD in BD patients. Sub group meta-analyses reported higher OCD prevalence rates in BD children and adolescents (24.2%, compared to 13.5% in adults), in BD-I patients (24.6%, compared to 13.6% in mixed BD patients), and among population-based studies (22.2%, compared to 13.2% in hospital-based studies). LIMITATIONS: Most studies use retrospective assessment scales with low sensitivity in discriminating true ego-dystonic obsessions from depressive ruminations that may bias results towards an overestimation of obsessive symptom prevalence. CONCLUSIONS: This first systematic review and meta-analysis of the prevalence and predictors of comorbid BD-OCD confirms that BD-OCD comorbidity is a common condition in psychiatry with children and adolescents and BD-I patients as the most affected subgroups.

Treatment of comorbid bipolar disorder and obsessive-compulsive disorder: a systematic review.

BACKGROUND: More than 20% of patients with bipolar disorder (BD) show lifetime comorbidity for obsessive-compulsive disorder (OCD), but treatment of BD-OCD is a clinical challenge. Although serotonin reuptake inhibitors (SRIs) are the first line treatment for OCD, they can induce mood instability in BD. An optimal treatment approach remains to be defined. METHODS: We systematically reviewed MEDLINE, Embase, PsychINFO and the Cochrane Library and retrieved data on clinical management of comorbid BD-OCD patients. Pharmacologic, psychotherapeutic and others alternative approaches were included. RESULTS: Fourteen studies were selected. In all selected studies BD-OCD patients received mood stabilizers. In the largest study, 42.1% of comorbid patients required a combination of multiple mood stabilizers and 10.5% a combination of mood stabilizers with atypical antipsychotics. Addition of antidepressants to mood stabilizers led to clinical remission of both conditions in only one study. Some BD-OCD patients on mood stabilizer therapy benefitted from adjunctive psychotherapy. LIMITATIONS: Most studies are case reports or cross-sectional studies based on retrospective assessments. Enrollment of subjects mainly from outpatient specialty units might have introduced selection bias and limited community-wide generalizability. CONCLUSIONS: Keeping in mind scantiness and heterogeneity of the available literature, the best interpretation of the available evidence appears to be that mood stabilization should be the primary goal in treating BD-OCD patients. Addition of SRI agents seems unnecessary in most cases, although it may be needed in a minority of BD patients with refractory OCD.

Diagnostic validity of comorbid bipolar disorder and obsessive-compulsive disorder: a systematic review.

OBJECTIVE: At least 50% of bipolar disorder (BD) patients have an additional diagnosis, one of the most difficult to manage being obsessive-compulsive disorder (OCD). Defining the nosology of BD-OCD comorbidity has important clinical implications, given that treatments for OCD can worsen BD outcomes. METHOD: A systematic review was conducted on: i) BD-OCD comorbidity lifetime prevalence and ii) on standard diagnostic validators: phenomenology, course of illness, heredity, biological markers, and treatment response. Relevant papers published through March 30th 2013 were identified searching the electronic databases MEDLINE, Embase, PsycINFO, and the Cochrane Library. RESULTS: Sixty-four articles met inclusion criteria. Lifetime comorbidity prevalence was 11-21% in BD patients and 6-10% in OCD patients. Compared to non-comorbid subjects, BD-OCD has a more episodic course of OC symptoms (up to 75% vs. 3%), typically with worsening during depression (78%) and improvement during mania/hypomania (64%), as well as a higher total mean number of depressive episodes (8.9±4.2 vs. 4.1±2.7) and perhaps more antidepressant-induced mania/hypomania (39% vs. 9%). CONCLUSION: In this first systematic review of BD-OCD comorbidity, it appears that OC symptoms are usually secondary to BD, rather than representing a separate disease.

[Vestibulo-oculomotor reflex recording using the scleral search coil technique. Review of peripheral vestibular disorders]. / Registro del reflejo vestibulooculomotor con la técnica de la bobina corneal en campo magnético (scleral search coil). Revisión de afecciones vestibulares periféricas.

Our goal is to review vestibulo-oculomotor reflex (VOR) studies on several peripheral vestibular disorders (Ménière's disease, vestibular neuritis, benign paroxysmal positional vertigo, superior canal dehiscence syndrome, and vestibular neuroma), using the scleral search coil (SSC) technique. Head movements are detected by vestibular receptors and the elicited VOR is responsible for compensatory 3 dimensional eye movements. Therefore, to study the VOR it is necessary to assess the direction and velocity of 3 dimensional head and eye movements. This can be achieved using the SCC technique. Interaction between a scleral search coil and an alternating magnetic field generates an electrical signal that is proportional to eye position. Ideally, eye rotation axis is aligned with head rotation axis and VOR gain (eye velocity/head velocity) for horizontal and vertical head rotations is almost 1. The VOR gain, however, for torsional head rotations is smaller and about 0.7.

[Inguinal hernioplasty after Shouldice]. / Ernioplastica inguinale secondo Shouldice.

The authors review their two-year experience of hernioplasty using a modified version of Shouldice's technique which includes the employment of a polyglyconate monofilament. Although the series of patients is chronologically limited, the findings appear to confirm that this is a valid alternative to other techniques proposed to date for treating inguinal hernia.
