Diagnostic criteria for major depressive disorder allow for heterogeneous symptom profiles but genetic analysis of major depressive symptoms has the potential to identify clinical and etiological subtypes. There are several challenges to integrating symptom data from genetically informative cohorts, such as sample size differences between clinical and community cohorts and various patterns of missing data.

We conducted genome-wide association studies of major depressive symptoms in three cohorts that were enriched for participants with a diagnosis of depression (Psychiatric Genomics Consortium, Australian Genetics of Depression Study, Generation Scotland) and three community cohorts who were not recruited on the basis of diagnosis (Avon Longitudinal Study of Parents and Children, Estonian Biobank, and UK Biobank). We fit a series of confirmatory factor models with factors that accounted for how symptom data was sampled and then compared alternative models with different symptom factors.

The best fitting model had a distinct factor for Appetite/Weight symptoms and an additional measurement factor that accounted for the skip-structure in community cohorts (use of Depression and Anhedonia as gating symptoms).

The results show the importance of assessing the directionality of symptoms (such as hypersomnia versus insomnia) and of accounting for study and measurement design when meta-analyzing genetic association data.

Schizotypal personality is a condition suffered by 4% of the population. It is defined by presenting interpersonal, behavioral and perceptual features similar to the clinical features of psychotic disorders, such as schizophrenia, in less intensity and dysfunctionality, but at risk of reaching psychosis.

Presentation of a clinical case about a patient with premorbid schizotypal personality traits presenting with an acute psychotic episode.

Literature review on association between schizotypal personality and psychosis.

A 57-year-old woman with a history of adaptive disorder due to work problems 13 years ago, currently without psychopharmacological treatment, goes to the emergency room brought by the emergency services due to behavioral alteration. She reports that “her husband and son wanted to sexually abuse her”, so she had to run away from home and has been running through the streets of the town without clothes and barefoot.

Her husband relates attitude alterations and extravagant behaviors of years of evolution, such as going on diets of eating only bread for 40 days or talking about exoteric and religious subjects, as believing that the devil got inside her husband through a dental implant. He reports that these behaviors have been accentuated during the last month. She has also created a tarot website, and has even had discussions with several users. She is increasingly suspicious of him, has stopped talking to him and stays in his room all day long, with unmotivated laughter and soliloquies.

It was decided to admit him to Psychiatry and risperidone 4 mg was started. At the beginning, she was suspicious and reticent in the interview. As the days went by, communication improved, she showed a relaxed gesture and distanced herself from the delirious ideation, criticizing the episode.

In recent years, there has been increasing interest in understanding the association between schizotypy and serious mental disorder. Several theories understand schizotypy as a natural continuum of personality that reveals genetic vulnerability and that can lead to psychotic disorder when added to precipitating factors. Other theories define schizotypy as a “latent schizophrenia” where symptoms are contained and expressed in less intensity.

Around 20% evolves to paranoid schizophrenia or other serious mental disorders. It is complex to distinguish between those individuals in whom schizotypy is a prodrome and those in whom it is a stable personality trait. To date, studies applying early psychotherapeutic or pharmacological interventions have had insufficient and contradictory results, and the follow-up and treatment of these individuals could be a stress factor and a stigma. Some studies are looking for reliable markers of evolution to schizophrenia in order to establish adequate protocols for detention, follow-up and treatment.

Delusional parasitosis, also known as delusional infestation or Ekbom’s syndrome, is a rare psychotic disorder characterized by the false belief that a parasitic skin infestation exists, despite the absence of any medical evidence to support this claim. These patients often see many physicians, so a multidisciplinary approach among clinicians is important. Many patients refuse any treatment due to their firm belief that they suffer from an infestation, not a psychiatric condition, so it is crucial to gain the trust of these patients.

The comprehensive review of this clinical case aims to investigate Ekbom syndrome, from a historical, clinical and therapeutic perspective.

Literature review based on delusional parasitosis.

A 65-year-old woman comes to the psychiatry consultation referred by her primary care physician concerned about being infested by insects that she perceives through scales on her skin for the last three months. She recognizes important impact on her functionality. She is also convinced that her family is being infected too. As psychiatric history she recognizes alcohol abuse in the past (no current consumption) and an episode of persecutory characteristics with a neighbor, more than ten years ago. On psychopathological examination, she shows delusional ideation of parasitosis, with high behavioral repercussions, cenesthetic and cotariform hallucinations, as well as feelings of helplessness and anger. Treatment with Pimozide was started and the patient was referred to dermatology for evaluation, a plan she accepted. Her primary care physician and dermatology specialist were informed about the case and the treatment plan. In the recent reviews, the patient is calmer, however, despite the corroboration of dermatology and in the absence of organic lesions in cranial CT, she is still unsatisfied with the results, remaining firm in her conviction of infestation. It was decided to start treatment with atypical neuroleptics (Aripiprazole), with progressive recovery of her previous functionality.

Despite the increase in the number of studies in recent years, there are still few studies on this type of delirium. The female:male ratio varies in the bibiliography (between 2:1 and 3:1). The onset is usually insidious, generally appearing as a patient who comes to his primary care physician convinced of having parasites in different skin locations. It is usual to observe scratching lesions or even wounds in search of the parasite. In the past, the most used and studied treatment was Pimozide. Currently the treatment of choice is atypical neuroleptics due to their lower side effects. The latest reviews on the prognosis of this disorder show data with percentages of complete recovery between 51% and 70%, and partial responses between 16.5% and 20%. Finally, for a good diagnosis and therapeutic management, it is important to achieve a multidisciplinary approach.

We identify a set of essential recent advances in climate change research with high policy relevance, across natural and social sciences: (1) looming inevitability and implications of overshooting the 1.5°C warming limit, (2) urgent need for a rapid and managed fossil fuel phase-out, (3) challenges for scaling carbon dioxide removal, (4) uncertainties regarding the future contribution of natural carbon sinks, (5) intertwinedness of the crises of biodiversity loss and climate change, (6) compound events, (7) mountain glacier loss, (8) human immobility in the face of climate risks, (9) adaptation justice, and (10) just transitions in food systems.

The Intergovernmental Panel on Climate Change Assessment Reports provides the scientific foundation for international climate negotiations and constitutes an unmatched resource for researchers. However, the assessment cycles take multiple years. As a contribution to cross- and interdisciplinary understanding of climate change across diverse research communities, we have streamlined an annual process to identify and synthesize significant research advances. We collected input from experts on various fields using an online questionnaire and prioritized a set of 10 key research insights with high policy relevance. This year, we focus on: (1) the looming overshoot of the 1.5°C warming limit, (2) the urgency of fossil fuel phase-out, (3) challenges to scale-up carbon dioxide removal, (4) uncertainties regarding future natural carbon sinks, (5) the need for joint governance of biodiversity loss and climate change, (6) advances in understanding compound events, (7) accelerated mountain glacier loss, (8) human immobility amidst climate risks, (9) adaptation justice, and (10) just transitions in food systems. We present a succinct account of these insights, reflect on their policy implications, and offer an integrated set of policy-relevant messages. This science synthesis and science communication effort is also the basis for a policy report contributing to elevate climate science every year in time for the United Nations Climate Change Conference.

We highlight recent and policy-relevant advances in climate change research – with input from more than 200 experts.

Maintenance electroconvulsive therapy (mECT) is an option in the treatment of affective disorders which progress is not satisfactory. It is certainly neglected and underused during the clinical practice.

To evaluate the efficacy of mECT in reducing recurrence and relapse in recurrent depression within a sample of three patients.

We followed up these patients among two years since they received the first set of electroconvulsive sessions. We applied the Beck Depression Inventory (BDI) in the succesives consultations for evaluating the progress.

The three patients were diagnosed with Recurrent Depressive Disorder (RDD). One of them is a 60 year old man that received initially a cycle of 12 sessions; since then he received 10 maintenance sessions. Other one is a 70 year old woman that received initially a cycle of 10 sessions; since then she received 6 maintenance sessions. The last one is a 55 year old woman that received initially a cycle of 14 sessions; since then she received 20 maintenance sessions.

All of them showed a significant reduction in depressive symptoms evaluated through BDI and clinical examination. In the first case, we found a reduction in the BDI from the first consultation to the last that goes from 60 to 12 points; in the second case, from 58 to 8 points; and in the last case, from 55 to 10 points. The main sections that improved were emotional, physical and delusional.

As side-effects of the treatment, we found anterograde amnesia, lack of concentration and loss of focus at all of them.

We find mECT as a very useful treatment for resistant cases of affective disorders like RDD.

It should be considered as a real therapeutic option when the first option drugs have been proved without success.

Medical-related professions are at high suicide risk. Suicide is a major cause of premature death among physicians, but the prevalence of suicide-related behaviors is inconsistent across studies.

Presenting a review of the prevalence and risk factors of suicide among physicians.

Search on Pubmed® and Medscape® databases with the following keywords: “physicians” and “suicide”. We focused on data from systematic reviews and meta-analyzes. The articles were selected by the authors according to their relevance.

Female and US physicians were at higher risk of suicidal behavior. Suicide decreased over time, especially in Europe. Some specialties might be at higher risk such as anesthesiologists, psychiatrists, general practitioners and general surgeons. It is well established that anesthesiologists tend to have much higher rates of substance abuse than other physicians. Psychiatrists are also known to have more mental distress, mental illness and burnout compared with other physician groups and have concerning rates of depression and psychotropic. Physicians are less likely to seek mental health services out of career concerns, culture and/ or a predisposition toward self-reliance. Additionally, retrospective toxicology screening of suicide data finds that physicians are more likely than nonphysicians to have positive results for antipsychotics, benzodiazepines, and barbiturates but not antidepressants.

Physicians are an at-risk profession of suicide, with women particularly at risk. The rate of suicide in physicians decreased over time, especially in Europe. The high prevalence of physicians who committed suicide attempt as well as those with suicidal ideation should benefits for preventive strategies at the workplace. Physician suicides are multifactorial, and further research into these factors is critical. Appropriate preventive and treatment measures should be implemented to reduce the risk of suicide-related behaviors in this population.

Subjective memory complaints remain a relevant aspect to be considered in patients with mild cognitive impairment. Likewise, their association with depressive symptoms, quality of life and cognitive performance is also an objective to be studied in such patients.

Our clinical case represents just one opportunity to study how memory complaints are related to depressive states and how they affect the quality of life of patients with mild cognitive impairment.

We conducted a bibliographical review by searching for articles in Pubmed.

PERSONAL HISTORY: Male, 73 years old, separated, residing alone in Valladolid. He has home help, a person comes to help him with the household chores. Little social and family circle.

He has a history of an admission in 2013 to this Short Hospitalization Unit for ethanol detoxification. Since then, he has been followed up in the Mental Health Unit. According to the reports, he has been diagnosed with depressive disorder and cluster B personality disorder.

Current psychopharmacological treatment: diazepam, olanzapine, duloxetine 60 mg, quetiapine.

Toxic habits: history of chronic ethanol consumption. Smoker. He denies other toxic habits.

The patient presents a worsening of his mood of 15 days of evolution, coinciding with a voluntary decrease of his psychopharmacological treatment that the patient has carried out on his own. He walks with the aid of a crutch. Hypomimic facies. Slowed language, circumstantial, with speech focused on current discomfort.

On assessment, he reports initial improvement after reducing his medication, but in recent days he has experienced a decrease in initiative accompanied by feelings of emptiness, sadness and loneliness. He refers to memory complaints for which he is awaiting evaluation by Neurology. The patient explains that at other times in his life he has presented self-harming ideas that he has been controlling. At this time he expresses desire for improvement and adequate future plans, and accepts plans to attend a memory workshop. He also reports visual hallucinations with no affective repercussions and preserved judgment of reality.

Treatment adjustment: Duloxetine 60 mg, 2cp/day. The patient is recommended to lead an active lifestyle and attend a day center or memory workshop.

In numerous patients with mild cognitive impairment, we have observed that memory complaints are closely related to depressive symptoms and to the patient’s functioning in daily life.

In one study memory complaints were a negative predictor of quality of life in these patients.

Therefore, in addition to considering the importance of treating depressive symptoms, it is also important to address quality of life in patients with mild cognitive impairment.

Patients with an alcohol use disorder frequently relapse after various efforts to quit. Admission to hospital units is a possible start to stop drinking alcohol and reach abstinence. Among the pharmacological strategies to quit this addiction are specific drugs, such as disulfiram or namelfen, which are widely studied. Hospitalized patients frequently initiate these medications to control addiction, but little is known about their efficacy after discharge in this group.

The aim is to determine whether the initiation of treatment with specific drugs for alcohol use disorder could help to maintain alcohol abstinence after admission to a General Hospital Psychiatric Ward. In addition, we want to check those factors associated with a higher rate of relapse in consumption.

We conducted a retrospective cross-sectional study of a group of patients admitted in 2018 to a psychiatric hospitalization ward due to alcohol use disorder and who expressed their desire to stop drinking. At the time of admission, we recorded sociodemographic data, consumption of other substances and alcohol family history. Patients initialized specific treatments to reduce and control alcohol consumption if they wanted. Twenty-four months after discharge, we acquired the number of relapses through new admissions, emergency room visits or outpatient follow-up data.

A sample of 36 patients (28 men) admitted to a psychiatric hospitalization ward was analyzed. At discharge, 17 accepted specific pharmacological treatments to reduce alcohol consumption. After a follow-up period of 24 months, 70.8% relapsed compared to 94.7% who did not accept treatment (χ2=4.001, DF=1, p=0.045, OR=0.13). There were no differences between the two groups in age, gender, amount of alcohol consumed, follow-up modality at discharge or if it was their first detoxification attempt. However, those who did not accept the specific pharmacological treatment consumed other drugs (41.1% vs 5.8%, χ2= 5.888, DF=1, p=0.015), had other history of mental disorder (64.7% vs 23.5%, χ2= 5.845, FD=1, p=0.015) and a higher proportion of relatives with alcohol consumption (81.8% vs 42.8%, χ2= 3.896, FD=1, p=0.048) more frequently. The time (in days) to relapse was faster in this group of patients (200.8 vs 402.7 , Z=-2.5413, p=0.005).

Accepting drug-specific treatment for alcohol use can be helpful for many patients who want to achieve alcohol abstinence. Among the factors that prevent the acceptance of this treatment is the consumption of other substances, comorbidity with another mental pathology and family history, which may involve genetic factors that favour addiction. This group of patients could benefit from a specific pharmacological treatment, although other psychosocial factors may also help.

Current psychiatric diagnoses, although heritable, have not been clearly mapped onto distinct underlying pathogenic processes. The same symptoms often occur in multiple disorders, and a substantial proportion of both genetic and environmental risk factors are shared across disorders. However, the relationship between shared symptoms and shared genetic liability is still poorly understood.

Well-characterised, cross-disorder samples are needed to investigate this matter, but few currently exist. Our aim is to develop procedures to purposely curate and aggregate genotypic and phenotypic data in psychiatric research.

As part of the Cardiff MRC Mental Health Data Pathfinder initiative, we have curated and harmonised phenotypic and genetic information from 15 studies to create a new data repository, DRAGON-Data. To date, DRAGON-Data includes over 45 000 individuals: adults and children with neurodevelopmental or psychiatric diagnoses, affected probands within collected families and individuals who carry a known neurodevelopmental risk copy number variant.

We have processed the available phenotype information to derive core variables that can be reliably analysed across groups. In addition, all data-sets with genotype information have undergone rigorous quality control, imputation, copy number variant calling and polygenic score generation.

DRAGON-Data combines genetic and non-genetic information, and is available as a resource for research across traditional psychiatric diagnostic categories. Algorithms and pipelines used for data harmonisation are currently publicly available for the scientific community, and an appropriate data-sharing protocol will be developed as part of ongoing projects (DATAMIND) in partnership with Health Data Research UK.

We summarize what we assess as the past year's most important findings within climate change research: limits to adaptation, vulnerability hotspots, new threats coming from the climate–health nexus, climate (im)mobility and security, sustainable practices for land use and finance, losses and damages, inclusive societal climate decisions and ways to overcome structural barriers to accelerate mitigation and limit global warming to below 2°C.

We synthesize 10 topics within climate research where there have been significant advances or emerging scientific consensus since January 2021. The selection of these insights was based on input from an international open call with broad disciplinary scope. Findings concern: (1) new aspects of soft and hard limits to adaptation; (2) the emergence of regional vulnerability hotspots from climate impacts and human vulnerability; (3) new threats on the climate–health horizon – some involving plants and animals; (4) climate (im)mobility and the need for anticipatory action; (5) security and climate; (6) sustainable land management as a prerequisite to land-based solutions; (7) sustainable finance practices in the private sector and the need for political guidance; (8) the urgent planetary imperative for addressing losses and damages; (9) inclusive societal choices for climate-resilient development and (10) how to overcome barriers to accelerate mitigation and limit global warming to below 2°C.

Science has evidence on barriers to mitigation and how to overcome them to avoid limits to adaptation across multiple fields.
