Procedure duration is an important predictor of patient outcomes in surgery. However, the relationship between procedure duration and adverse events in congenital cardiac catheterization is largely unexplored.

All cases entered into the Congenital Cardiac Catheterization Project on Outcomes from 2014 to 2017 were included. Cases were ordered from shortest to longest case length, minus time spent managing adverse events, for each case type. The outcomes, Level 3bc/4/5 and 4/5 adverse event rates, were calculated for cases above and below the 75th percentile for case length. To identify an independent relationship between case length and outcomes, the case length percentile was added to the CHARM II risk model.

Among 14,704 catheterizations, longer cases (>75th percentile for case length) had Level 4/5 rates that were 2.2% and 2.7% compared to cases ≤75th percentile with adverse event rates of 0.9% and 1.4% for diagnostic and interventional cases, respectively. Level 3bc/4/5 rates were 5.0% and 8.4% in longer cases compared to 2.4% and 5.4% for diagnostic and interventional cases, respectively. After adding case length to the CHARM II risk model, case length 50th–75th percentile had an odds ratio (OR) of 1.4, 75th–90th percentile an OR of 1.56, and >90th percentile an OR of 2.24 as compared to cases with case length <50th percentile (p ≤ 0.001 for all).

Longer case lengths are associated with clinically important and life-threatening adverse events in congenital cardiac catheterization, even after accounting for known risk factors. Case length may be an important target for future quality improvement work.

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.

tardive dysphoria is a relatively new term used to describe the phenomenon of clinical worsening of depression after long-term antidepressant use. Most of the theories proposed to explain this talk about antidepressants tachyphylaxis that implies the loss of efficacy with its prolonged use, or even a pro-depressant effect of antidepressants when used for long periods of time.

to explore the concept of tardive dysphoria, potential causes and clinical implications, by making a literature review on the topic. Moreover we pretend to understand the challenges in its diagnosis and treatment.

bibliographical search in PubMed database, using the key-words “long-term antidepressant”, “tardive dysphoria” and “antidepressant tachyphylaxis”, limited to works published in the last twenty years.

from our search resulted 53 articles, 26 were chosen for further analysis.

the concept of tardive dysphoria is controversial, namely doubt persists if it constitutes a clinical entity by itself caused by long-term antidepressant use or if it simply relates to cases of treatment-resistant depression. We conclude that it is necessary further investigation in this area given the significant implications on clinical practice specifically in the psychopharmacological treatment with antidepressants, which is very common in psychiatric and general practices, with antidepressants being used to treat many mental health conditions.

fibromyalgia is a modern disease, with growing investigation concerning its etiology and treatment. It has become a very prevalent diagnosis and total remission of symptoms is the exception which is dramatic considering the socio-occupational impact of this highly debilitating disease.

to review the updates in the pathophysiology and treatment of fibromyalgia, especially when it is refractory to treatment. The authors also intend to better understand where fibromyalgia belongs, is it in psychiatry as a functional disorder or in rheumatology as an auto-immune disease?

bibliographical search in PubMed database, using the key-words “fibromyalgia” and “psychiatry”, limited to works published in the last 10 years.

from our search resulted 158 articles, from reading of abstracts 30 were chosen for further reading.

concerning the etiology of this disease, on the one hand psychological factors cannot be neglected since there are several studies finding a positive correlation between stressors like history of physical abuse and fibromyalgia in adulthood, on the other hand investigation and meta-analysis have found that the immune-inflammatory response system might be altered with dysregulation of pro and anti-inflammatory cytokines and cell-mediated immunity. Regarding treatment, symptom relief is often unsatisfactory with classical treatment and so adjunct treatment such as electrical neuromodulation and aerobic exercise might, respectively, be effective in reducing pain and depressive symptoms, thereby improving quality of life, and in improving fatigue and in a lesser degree sleep.

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.

The population ageing is a reality associated with an increase in prevalence of Dementia. The use of benzodiazepines is often postulated as a risk factor in these syndromes.

Contrary to recommendations for its short-time use, long-term and chronic use are common, with an estimated 8,7% of elderly people in the US taking benzodiazepines.

To clarify the most recent evidence on the use of benzodiazepines and the risk of developing dementia.

Non-systematic review of literature, using PubMed as database and filtering the results for meta-analysis.

Four articles were included in this review.

Zhong G et al. concluded that risk of dementia increased in consumers of benzodiazepines and it was associated with higher doses.

In turn, AlDawasari A et al., when trying to clarify the use of different sedative-hypnotic drugs, found and increased risk with the consumption of benzodiazepines. After exclusion of articles with confounders and adjustment for protopathic bias, the risk was not maintained.

Lucchetta RC et al. concluded that the risk exists but without inferring differences between doses or duration of action.

Finally, Penninkilampi R e Eslick GD investigated this association, after controlling for the protopathic bias, concluding, contrary to AlDawasari et al., that the association benzodiazepines consumption and dementia do not result from this bias.

We cannot draw robust and concrete conclusions between benzodiazepines consumption and the pathogenesis of dementia because not only is the literature limited, but results are also heterogeneous.

However, these prescriptions must be carried out cautiously, especially in the elderly, due to the known adverse effects associated with them.

Although the link between alcohol involvement and behavioral phenotypes (e.g. impulsivity, negative affect, executive function [EF]) is well-established, the directionality of these associations, specificity to stages of alcohol involvement, and extent of shared genetic liability remain unclear. We estimate longitudinal associations between transitions among alcohol milestones, behavioral phenotypes, and indices of genetic risk.

Data came from the Collaborative Study on the Genetics of Alcoholism (n = 3681; ages 11–36). Alcohol transitions (first: drink, intoxication, alcohol use disorder [AUD] symptom, AUD diagnosis), internalizing, and externalizing phenotypes came from the Semi-Structured Assessment for the Genetics of Alcoholism. EF was measured with the Tower of London and Visual Span Tasks. Polygenic scores (PGS) were computed for alcohol-related and behavioral phenotypes. Cox models estimated associations among PGS, behavior, and alcohol milestones.

Externalizing phenotypes (e.g. conduct disorder symptoms) were associated with future initiation and drinking problems (hazard ratio (HR)⩾1.16). Internalizing (e.g. social anxiety) was associated with hazards for progression from first drink to severe AUD (HR⩾1.55). Initiation and AUD were associated with increased hazards for later depressive symptoms and suicidal ideation (HR⩾1.38), and initiation was associated with increased hazards for future conduct symptoms (HR = 1.60). EF was not associated with alcohol transitions. Drinks per week PGS was linked with increased hazards for alcohol transitions (HR⩾1.06). Problematic alcohol use PGS increased hazards for suicidal ideation (HR = 1.20).

Behavioral markers of addiction vulnerability precede and follow alcohol transitions, highlighting dynamic, bidirectional relationships between behavior and emerging addiction.

The UK Soft Drinks Industry Levy (SDIL) (announced in March 2016; implemented in April 2018) aims to incentivise reformulation of soft drinks to reduce added sugar levels. The SDIL has been applauded as a policy success, and it has survived calls from parliamentarians for it to be repealed. We aimed to explore parliamentary reaction to the SDIL following its announcement until two years post-implementation in order to understand how health policy can become established and resilient to opposition.

Searches of Hansard for parliamentary debate transcripts that discussed the SDIL retrieved 186 transcripts, with 160 included after screening. Five stages of Applied Thematic Analysis were conducted: familiarisation and creation of initial codebooks; independent second coding; codebook finalisation through team consensus; final coding of the dataset to the complete codebook; and theme finalisation through team consensus.

Between the announcement (16/03/2016) – royal assent (26/04/2017), two themes were identified 1: SDIL welcomed cross-party 2: SDIL a good start but not enough. Between royal assent – implementation (5/04/2018), one theme was identified 3: The SDIL worked – what next? The final theme identified from implementation until 16/03/2020 was 4: Moving on from the SDIL.

After the announcement, the SDIL had cross-party support and was recognised to have encouraged reformulation prior to implementation. Lessons for governments indicate that the combination of cross-party support and a policy’s documented success in achieving its aim can help cement the resilience of it to opposition and threats of repeal.

White matter hyperintensity (WMH) burden is greater, has a frontal-temporal distribution, and is associated with proxies of exposure to repetitive head impacts (RHI) in former American football players. These findings suggest that in the context of RHI, WMH might have unique etiologies that extend beyond those of vascular risk factors and normal aging processes. The objective of this study was to evaluate the correlates of WMH in former elite American football players. We examined markers of amyloid, tau, neurodegeneration, inflammation, axonal injury, and vascular health and their relationships to WMH. A group of age-matched asymptomatic men without a history of RHI was included to determine the specificity of the relationships observed in the former football players.

240 male participants aged 45-74 (60 unexposed asymptomatic men, 60 male former college football players, 120 male former professional football players) underwent semi-structured clinical interviews, magnetic resonance imaging (structural T1, T2 FLAIR, and diffusion tensor imaging), and lumbar puncture to collect cerebrospinal fluid (CSF) biomarkers as part of the DIAGNOSE CTE Research Project. Total WMH lesion volumes (TLV) were estimated using the Lesion Prediction Algorithm from the Lesion Segmentation Toolbox. Structural equation modeling, using Full-Information Maximum Likelihood (FIML) to account for missing values, examined the associations between log-TLV and the following variables: total cortical thickness, whole-brain average fractional anisotropy (FA), CSF amyloid ß42, CSF p-tau181, CSF sTREM2 (a marker of microglial activation), CSF neurofilament light (NfL), and the modified Framingham stroke risk profile (rFSRP). Covariates included age, race, education, APOE z4 carrier status, and evaluation site. Bootstrapped 95% confidence intervals assessed statistical significance. Models were performed separately for football players (college and professional players pooled; n=180) and the unexposed men (n=60). Due to differences in sample size, estimates were compared and were considered different if the percent change in the estimates exceeded 10%.

In the former football players (mean age=57.2, 34% Black, 29% APOE e4 carrier), reduced cortical thickness (B=-0.25, 95% CI [0.45, -0.08]), lower average FA (B=-0.27, 95% CI [-0.41, -.12]), higher p-tau181 (B=0.17, 95% CI [0.02, 0.43]), and higher rFSRP score (B=0.27, 95% CI [0.08, 0.42]) were associated with greater log-TLV. Compared to the unexposed men, substantial differences in estimates were observed for rFSRP (Bcontrol=0.02, Bfootball=0.27, 994% difference), average FA (Bcontrol=-0.03, Bfootball=-0.27, 802% difference), and p-tau181 (Bcontrol=-0.31, Bfootball=0.17, -155% difference). In the former football players, rFSRP showed a stronger positive association and average FA showed a stronger negative association with WMH compared to unexposed men. The effect of WMH on cortical thickness was similar between the two groups (Bcontrol=-0.27, Bfootball=-0.25, 7% difference).

These results suggest that the risk factor and biological correlates of WMH differ between former American football players and asymptomatic individuals unexposed to RHI. In addition to vascular risk factors, white matter integrity on DTI showed a stronger relationship with WMH burden in the former football players. FLAIR WMH serves as a promising measure to further investigate the late multifactorial pathologies of RHI.

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.
