Research suggests that the gender gap in alcohol (Alc.) consumption may be narrowing, with increasing consumption by the female population. For women, the equivalent of 20-25 grams/day is considered harmful consumption. Many of the harmful effects of alcohol consumption occur more rapidly and more severely in women, yet the majority do not seek treatment
Objectives
To describe the prevalence of harmful use of alcohol in women admitted to hospital for other mental illness.
Methods
Retrospective observational study of six months duration. Data was collected from all patients admitted to the hospital during the period of study, with no specific exclusion criteria. Descriptive statistics were performed.
Results
During the study period, 312 patients were admitted to the hospital, 52.8% of whom were women, 21.8% of whom had a harmful use of Alc. The prevalence of harmful Alc. use in the different mental illnesses was: 22.2% in schizophrenia or other psychoses, 13.9% in bipolar affective disorder, 11.1% in depressive disorder, 13.9% in personality disorder, 19.4% in substance use disorder, 13.9% for other diagnoses and a prevalence of 5.56% for those of unknown diagnosis
Conclusions
In recent years, it has been shown that the overall prevalence of harmful alcohol use and alcohol use disorder has increased in women. They tend to seek care in settings where their alcohol problems may not be recognised. They have lower social support for treatment participation and greater barriers to accessing treatment, resulting in even higher rates of co-occurring medical and mental health problems. Prevention strategies and intervention programmes should be adapted to the specific needs of women, taking into account both individual risk factors and socio-cultural contexts
We analyse the small-scale characteristics, such as enstrophy, total strain and normality/non-normality, in the three-dimensional, separated flow around a NACA 0018 wing using direct numerical simulations. The angle of attack is $10^\circ$ and the Reynolds number (based on the chord length) is $Re_c=5000$. The role of non-normality is investigated by performing Schur decomposition of the velocity gradient tensor. We also apply the Schur decomposition to derive new expressions for the production of enstrophy and total strain arising from the mean flow inhomogeneity. We focus on two sections of the flow, across the recirculating zone and along the transitioning shear layer, and compare our results with homogeneous isotropic turbulence (HIT). Within the recirculating region, the non-normality index is approximately 0 (and close to the HIT value), indicating almost equal normal and non-normal contributions. However, in the separating layer non-normal effects strongly dominate, especially in the region of kinetic energy growth. Only in the decay region do the values of the non-normality index gradually approximate HIT values. The production of enstrophy due to vortex stretching is dominated by the mixed (interaction) term, where normal strain stretches non-normal vorticity. The same component also dominates the strain self-amplification term. The contributions of different QR regions to the production terms are also examined. Production due to mean strain rate is triggered upstream compared with production due to fluctuating strain fields.
In spite of the upturn in the economy and in employment that has been observed in the EU since 2013 to 2019 (and after COVID-19 crisis), the gap between the figures for indicators of economic growth and those for the trends in domestic living conditions continues to be very wide; growth and newly created jobs are not resulting in a generalised improvement in the welfare of the population. This paper seeks to demonstrate that the recovery period after the Great Recession has not been one of truly inclusive recovery and to provide tentative explanations for this. We focus on the five main EU countries before Brexit. We conclude that the incidence of poverty associated with part-time work is now somewhat greater (‘in-work poverty’) and also that there has been strong containment of wages in the leading countries of the EU over the period under study, and even falls in real wages. At least, redistribution policies have shown themselves to be effective in reducing poverty.
This work presents a reflection on the meaning and significance of knowledge coproduction in the field of glaciology. We start by invoking the paradigm of Structure–Form–Environment Interplay (SFEI) to formulate a generalised definition of glaciology, which highlights the relevance of knowledge coproduction. The adoption of a relational view of glaciological knowledge leads us to identify five core dimensions of knowledge coproduction: purpose, ethics, ambiguity, inclusion/exclusion, and relationships. Based on those dimensions, we delve into the decisive methodological aspects of the coproduction process, namely the definition of its purpose, the identification of participants, the organisation of the process, the recognition of ambiguity in Ways of Knowing (WoKs), and the consideration of ethical implications. In addition to the already known three stages of knowledge coproduction process (codesign, codevelopment, and codelivery), we propose the inclusion of an additional preparation stage, which entails the acknowledgment of the identity and involvement of all human and nonhuman participants, their positionality, and means to ensure their cultural and ontological safety. We reason that knowledge coproduction does not replace the scientific method, but rather complements it, eliciting the possibility to unveil deeper insights that might be difficult to attain through unilateral means.
Medical assistance in dying for mental illness as a sole underlying medical condition (MAiD MI-SUMC) is a controversial and complex policy in terms of psychosocial and ethical medical practice implications. We discuss the status of MAiD MI-SUMC in Canada and argue for the use of the UK Medical Research Council's framework on complex interventions in programme evaluations of MAiD MI-SUMC. It is imperative to carefully and rigorously evaluate the implementation of MAiD MI-SUMC to ensure an understanding of the multiple facets of implementation in contexts permeated by unique social, economic, cultural and historical influences, with a correspondingly diverse array of outcomes. This requires a complexity-informed programme evaluation focused on context-dependent mechanisms and stakeholder experiences, including patients, service providers and other people affected by the policy. It is also important to consider the economic impact on health and social welfare systems. Such evaluations can provide the data needed to guide evidence-informed decision-making that can contribute to safer implementation and refinement of MAiD MI-SUMC.
The aim of the present study was to analyse the effects of the transcranial random noise stimulation (tRNS) technique when placed on the left dorsolateral prefrontal cortex (L-DPFC) and left inferior frontal gyrus (L-IFG), for the improvement of verbal fluency performance and creativity skills in a group of multilingual healthy adults.
Participants and Methods:
Fifty healthy adults, aged 18-47 years, participated in the study. All of them were native Spanish speakers of which three were bilingual (Spanish and English) and 47 were multilingual (Spanish, Basque and English). The study had a randomized, counterbalanced, double-blind, sham-controlled design. The participants were randomly allocated to either a tRNS active group or a placebo-control group. All participants were tested individually in one session divided into three parts: (1) baseline, (2) online, and (3) offline assessment. In the active condition, a 1.5mA current (100-500 Hz) was delivered for 20 minutes (online phase). Participants’ verbal fluency was assessed through semantic and phonemic verbal fluency tasks in three different languages (Spanish, Basque and English), while creativity was assessed in their native language with the Remote Associations Test (RAT, pre and post forms) for convergent thinking, and with the Unusual Uses subtest (UU, pre and post forms) for divergent thinking. In addition, the linguistic profile of the participants was evaluated with the Language Experience and Proficiency Questionnaire (LEAP-Q), and their processing speed and cognitive flexibility were assessed with the Stroop Color and Word Test (SCWT).
Results:
The results showed significant differences in phonemic fluency between the groups during the online assessment in Spanish (F= 5.31, p = 0.026), and in the offline assessments in Spanish (F=6.44, p = 0.015) and English (F=10.80, p = 0.002), with participants in the active condition performing better. While no differences were observed in the performance of the groups in verbal fluency in Basque, neither in the online (F=1.06, p = 0.31), nor in the offline assessment (F=2.62, p = 0.11). Furthermore, no significant differences were observed between groups in semantic verbal fluency tasks in any of the languages, neither during stimulation nor offline. However, there were no differences between conditions in the online (Spanish, F=0.86, p = 0.35; English, F=2.95, p = 0.09; and Basque, F=0.01 p = 0.94) and offline (Spanish, F=2.53, p = 0.11; English, F=0.74, p = 0.39; and Basque, F=1.39, p = 0.24) semantic tasks. In creativity, significant differences were observed between groups on the RAT (F=9.58, p = 0.003), while no differences were observed in the performance of any of the three dimensions of the UU (Originality, F=0.44, p = 0.51; Flexibility, F=0.42, p = 0.51; Fluency, F=0.69, p = 0.41). In the SCWT, statistically significant differences were only observed in the colour-word part (F=7.60, p = 0.008) during the online assessment, showing a better performance of the participants under the tRNS condition compare to the sham condition.
Conclusions:
The results obtained in this study suggest that the excitatory effects of tRNS over the L-DLPFC L-IFG could contribute to the improvement of phonemic verbal fluency and verbal convergent thinking, in healthy individuals.
In the last decade, the prevalence of THC use is increasing among adolescents and adults. There is also strong evidence to suggest that cannabis use is associated with psychiatric comorbidities. The strongest evidence is found between cannabis use and psychotic disorder. However, the literature shows that those who have used cannabis in the past or for a large part of their lives are at higher risk of mood disorders, anxiety, personality disorder or other drug use than those who do not use cannabis in a harmful way.
Objectives
To provide an overview of the association between cannabis use and the different mental pathologies presented by the patients admitted during the study period. To describe the prevalence of THC use in the study according to the mental pathology presented by the patient.
Methods
A retrospective observational descriptive study was developed for 3 months, of all patients admitted to the acute unit of the psychiatric hospital. No exclusion criteria were included.
Results
During the period of study 172 patients were admitted to the hospital, classified according to the main diagnosis we have: 49 patients suffer from schizophrenia, 26 bipolar affective disorder, 20 with depressive disorder, 20 with personality disorder, 19 with substance use disorder, 18 with other unspecified disorders and 20 patients with no known previous diagnosis. The prevalence of THC use in the study sample according to diagnosis, would be schizophrenia 16%, Bipolar affective disorder 19%, Depressive disorder 5%, Personality disorder 45%, Substance use disorder 21%, Unspecified disorders 11% and patients with no known previous diagnosis 10%.
Conclusions
The results obtained in the study in terms of THC use are in agreement with those obtained in the literature. In our study, we observed that cannabis use is associated with psychotic disorders as well as with mood, personality and substance abuse disorders. Given that the frequency of use has increased and there is a strong association with different comorbid psychiatric diagnoses, guidance on modifications in medication strategies might be necessary.
Patients with mental disorders frequently become non-adherent during their long term prescribed treatment. This situation frequently triggers clinical worsening and hospital admission. Therefore, non-adherence may result in poorer long term clinical outcomes and has economic implications for health-care providers (Carlos De las Cuevas et al. Neuropsychopharmacol Hung 2021; 23(4):347-362).
Objectives
- To describe the adherence to oral and long acting injectable treatment in the sample of patients that were admitted to the short stay hospital unit during the period of study.
- To describe the adherence to treatment amongst psychiatric diagnosis in the sample of study.
Methods
It was a retrospective observational study with a duration of three months. Data was collected from all patients admitted to the short stay hospital unit during the period of study and there were no specific exclusion criteria. Descriptive statistics were performed. To assess the adherence to pharmachological treatment the patient report, the family report and the pharmacy dispensation according to the existent informatic prescription platform was considered. Regarding the long acting injectable treatment the formulary of administration in the clinical history was checked.
Results
During the period of study 172 patients were admitted to the short stay hospital unit. Of those, 146 patients had a previous pharmacologic prescription. Data of treatment was not possible to obtain in 7 patients. In the sample of study, 83.5% were on oral and 16.5% on long acting injectable treatment. The general adherence to treatment in the sample was 61.87%. In the oral treatment group the adherence was 58.4% and in the long acting injectable treatment group was 65.2%.
Amongst the different psychiatric diagnoses the outcomes of adherence to treatment were: 60.4% in schizophrenia and related psychosis, 62.5% in bipolar disorder, 78.6% in depression, 58.3% in personality disorders and 62% in addictive disorders.
Conclusions
In our descriptive study adherence to treatment was higher in the long acting injectable treatment group, agreeing with the existent scientific literature.
The results of adherence for schizophrenia and bipolar disorder are similar to the ones found in scientific literature but differ from the ones for depression, being higher in our sample (Judit Lazary et al. Neuropsychopharmacol Hung 2021;23(4): 347-362). Moreover, in scientific literature it is found a similar prevalence of adherence across diagnosis (for schizophrenia, bipolar disorder and depression) whereas in our sample patients with depression showed a different and higher adherence to treatment (Judit Lazary et al. Neuropsychopharmacol Hung 2021;23(4): 347-362). In our sample, patients with personality disorders had the lowest adherence to treatment.
Patients with mental disorders have a decreased life expectancy, being the main reason the cardiovascular disease. An important proportion of patients present a comorbid drug consumption. Amongst drugs, alcohol is the most frequent, and it is associated with a higher cardiovascular risk. The metabolic syndrome is one of the most employed tools to assess cardiovascular risk.
Objectives
- To describe the demographic characteristics of the patients with an active alcohol consumption that were admitted to the hospital during the period of study.
- To describe the prevalence of metabolic syndrome in the sample, according to the Adult Treatment Panel III (ATP-III) criteria.
Methods
Retrospective observational study of three months duration. Data was collected from all patients admitted to the hospital during the period of study, with no specific exclusion criteria. Descriptive statistics were performed.
Results
During the period of study 172 patients were admitted to the hospital (56.4% women and 43.6% men). A 44.8% presented alcohol consumption (25% sporadically, 6.4% weekly and 13.4% daily). Amongst women, 1% presented daily and 1% weekly consumption. Amongst men, 21.3% presented daily and 5.3% weekly consumption.
The prevalence of metabolic syndrome in the study sample was 29.11%. In the alcohol consumption group, the prevalence was 24.7% and differed according to the pattern of consumption: 43.5% in the daily consumption group, 27.3% in the weekly and 14% in the sporadically consumption group.
Conclusions
On the one hand, in the sample of study a higher percentage of men present an active alcohol consumption, compared to women. It is remarkable the high percentage of daily alcohol consumption amongst men in our sample.
On the other hand, the prevalence of metabolic syndrome in our sample is similar to the one found in scientific literature regarding patients with mental disorders. It is noteworthy in our sample the increased prevalence of metabolic syndrome found in patients with a daily alcohol consumption, and a decreased prevalence in those with a sporadic pattern.
Patients affected by mental disorders are known to have a decreased life expectancy.
One of the main reasons are cardiovascular diseases. It is known that tobacco and hypertension are risk factors to develop them. WHO estimates that hypertension is diagnosed and treated in less than half of adults with hypertension, and even less in patients with severe mental illness.
Objectives
To describe the demographic characteristics of patients with tobacco comsumption and hypertension admitted to a short-term hospitalization unit.
Methods
A three-month retrospective observational study. Data were collected by interviewing incoming patients and performing a blood pressure measurement, with no exclusion criteria.
Results
Of 172 patients admitted, 100 were smokers of whom 49 were men and 51 were women. Among the smokers, a total of 18 patients were diagnosed with hypertension and 79 were not diagnosed. Within the group of patients not diagnosed with hypertension, elevated blood pressure was recorded in 5 of them. A total of 67 patients were non-smokers, 23 of whom were male and 44 female. Among the non-smokers, 19 were diagnosed with hypertension and 48 were not, despite which elevated blood pressure levels were recorded in 4 of them. No data were collected from 5 patients.
Conclusions
The prevalence of smokers in our sample was 58%. The prevalence of patients diagnosed with hypertension was 21,51% which is coherent with the existent literature. We did not find a higher percentage of hypertensive patients among the smokers admitted. There were patients who suffered from hypertension and were not diagnosed or treated previously.
Thyroid disorders can present with psychiatric symptons similar to depression, and, at the same time, certain treatments, like litio, can cause changes in thyroid function. Given, therefore, the importance for the treatment and care of patients, the study of thyroid function is one of the parametres that should be requested in patients with psychiatric pathology.
Objectives
To study the frequency of thyroid disorders in patients who where admitted to a psychiatric short stay unit.
Methods
Retrospective descriptive observational study is carried out in the acute stay unit of a psychiatric hospital. As a sample, all patients admitted to the unit over a period of three months. During admission, their sociodemographic data, the treatment they receive and their diagnosis are recorded. Secondly, blood test are performed whith differents parameters, including TSH values.
Results
In the total sample of 172 patients, 8 of them have TSH abnormalities. 7 of them, all women, present hypothyroidism values.
A single male patient presented values of hyperthryroidism.
Conclusions
According to the present study, 4,6% of the patients present alterations at the TSH at admission, although except in one case, the values were not markedly altered.
The thyroid study at admission allows detecting cases of altered TSH that are amenable to treatment and monitoring.
Incidence of alcohol abuse in our country is high, although it is still under-diagnosed and under-treated. The WHO estimates that a total of 3.3 million deaths worldwide per year are related to alcohol consumption.
Objectives
The main objective is to describe the pattern of alcohol consumption in a sample of patients who are admitted to our psychiatric hospital for different reasons, relating with previous diagnoses.
Methods
A retrospective observational descriptive study was carried out in the acute care unit of the psychiatric hospital, after approval of the corresponding protocol by the ethics committee. All patients admitted to this unit during a three-month period were taken as a sample. During admission, sociodemographic data, drug use, treatment type and time and previous diagnoses were collected.
Results
Out of 172 patients, 81 reported being abstemious, 45 declared occasional consumption, 11 weekly and 22 daily consumption. There is no data about 13 patients. Among those who reported daily alcohol consumption, 59% had a previous diagnosis of Substance Use Disorder (SUD), 23% a previous diagnosis of Schizophrenia, 13.5% of Bipolar Disorder and finally 4.5% of Depressive Disorder. All the patients with a previous diagnosis of SUD reported consumption of more than 10 SDUs/day, the group with Schizophrenia stated less than 5 SDUs/day, of the group with T. Bipolar between 7-10 SDUs/day and with T. Depressive 5 SDUs/day.
Conclusions
The results obtained are consistent with the literature in relation to the under-diagnosis of alcohol use disorder, taking into account that 40% of patients in the sample with daily alcohol consumption previously had not such a diagnosis and it was not recorded in their medical history. For this reason, and for the sake of being able to treat them, it is essential to question all patients about alcohol consumption, whatever the reason for their admission.
In this paper we propose a methodology for the efficient implementation of machine learning (ML)-based methods in particle-in-cell (PIC) codes, with a focus on Monte Carlo or statistical extensions to the PIC algorithm. The presented approach allows for neural networks to be developed in a Python environment, where advanced ML tools are readily available to proficiently train and test them. Those models are then efficiently deployed within highly scalable and fully parallelized PIC simulations during runtime. We demonstrate this methodology with a proof-of-concept implementation within the PIC code OSIRIS, where a fully connected neural network is used to replace a section of a Compton scattering module. We demonstrate that the ML-based method reproduces the results obtained with the conventional method and achieves better computational performance. These results offer a promising avenue for future applications of ML-based methods in PIC, particularly for physics extensions where a ML-based approach can provide a higher performance increase.
Wind turbine towers are subjected to highly varying internal loads, characterized by large uncertainty. The uncertainty stems from many factors, including what the actual wind fields experienced over time will be, modeling uncertainties given the various operational states of the turbine with and without controller interaction, the influence of aerodynamic damping, and so forth. To monitor the true experienced loading and assess the fatigue, strain sensors can be installed at fatigue-critical locations on the turbine structure. A more cost-effective and practical solution is to predict the strain response of the structure based only on a number of acceleration measurements. In this contribution, an approach is followed where the dynamic strains in an existing onshore wind turbine tower are predicted using a Gaussian process latent force model. By employing this model, both the applied dynamic loading and strain response are estimated based on the acceleration data. The predicted dynamic strains are validated using strain gauges installed near the bottom of the tower. Fatigue is subsequently assessed by comparing the damage equivalent loads calculated with the predicted as opposed to the measured strains. The results confirm the usefulness of the method for continuous tracking of fatigue life consumption in onshore wind turbine towers.
We consider a robust class of random non-uniformly expanding local homeomorphisms and Hölder continuous potentials with small variation. For each element of this class we develop the thermodynamical formalism and prove the existence and uniqueness of equilibrium states among non-uniformly expanding measures. Moreover, we show that these equilibrium states and the random topological pressure vary continuously in this setting.
The coronavirus disease 2019 (COVID-19) pandemic has been a global challenge. High mortality rates have been reported in some risk groups, including patients with pre-existing mental disorders.
Methods
We used electronic health records to retrospectively identify people infected due to COVID-19 (between March 2020 and March 2021) in the three territories of the Basque Country. COVID-19 cases were defined as individuals who had tested positive on a reverse transcription-polymerase chain reaction (PCR) test. Univariate and multivariate logistic regression models and multilevel analyses with generalized estimated equations were used to determine factors associated with COVID-19-related mortality and hospital admission.
Results
The COVID-19 mortality rate was increased for patients with psychotic disorders [odds ratio (OR) adjusted: 1.45, 95% confidence interval (CI) (1.09–1.94), p = 0.0114] and patients with substance abuse [OR adjusted: 1.88, 95% CI (1.13–3.14, p < 0.0152)]. The mortality rate was lower for patients with affective disorders [OR adjusted: 0.80, 95% CI (0.61–0.99), p = 0.0407]. Hospital admission rates due to COVID-19 were higher in psychosis [OR adjusted: 2.90, 95% CI (2.36–3.56), p < 0.0001] and anxiety disorder groups [OR adjusted: 1.54, 95% CI (1.37–1.72), p < 0.0001]. Among admitted patients, COVID-19 mortality rate was decreased for those with affective disorders rate [OR adjusted: 0.72, 95% CI (0.55–0.95), p = 0.0194].
Conclusions
COVID-19-related mortality and hospitalizations rates were higher for patients with a pre-existing psychotic disorder.
It means quality of life according to WHO (1993) “The perception of an individual of his situation in life, within the cultural context and values in which they live and in relation to their objectives, expectations, values and interests”.The aim of the present study is to know the subjective perception of the schizophrenics on their health.
Method
A sample of 67 patients receiving care in community mental health services (day hospital) has been evaluated using the SF-36 scale.
The results were compared with the population national values of reference to the same scale.
Results
We found statistically significant differences between groups for the following items: General Health (t =-2,81; p=0,004), Vitality (t =-3,37; P=0,000; Social Functioning t =-4.11; p = 0,000); Emotional Role (t =-2,269; p=0,023) and Mental Health (T =-2,67; p = 0,007).
Conclusions
The studied patients have a worse perception it brings over of his general health that the rest of the Spanish population; likewise they perceive a major detriment as for his social functioning that is a rest of the Spanish population. This way, the physical health of the patients with schizophrenia needs a control and a specific follow-up to guarantee that his life expectancy, his quality of life and his social functioning are similar to those of the general population.

Previous work suggests that reaction time variability (RTV) in attentional tasks, as a measure of cognitive stability, is associated with degree of Val loading in COMT Val158Met genotype, and that this association may be relevant for the aetiology of schizophrenia. This study examined (i) to what degree RTV pertaining to tasks of varying cognitive complexity would be associated with increased risk for schizophrenia and (ii) to what degree this would be mediated by Val loading.
Methods:
COMT genotyping was investigated in a sample of 23 patients with schizophrenia, 33 first-degree relatives, and 21 controls. All participants performed the Flanker continuous performance test.
Results:
Schizophrenia liability was associated with number of correct trials of the Flanker test, but not with RTV, and this association was not mediated by COMT Val158Met genotype. Similarly, Met loading was associated with number of correct trials and with RTV, but this was not mediated by schizophrenia liability.
Conclusions:
Associations between COMT Val158Met genotype and RTV do not appear to reflect transmission of schizophrenia liability in families. Differential associations with Val and Met alleles across studies suggest indirect effects through gene–gene interactions or the influence of a functional polymorphism near COMT Val158Met.
Anti-NMDA-receptor encephalitis is subacute disorder that has been recently described in young women and girls who often present neuropsychiatric symptoms as first clinical features; thus, it is common that they receive an initial assessment, diagnose or even treatment by a specialist in Psychiatry.
Objectives
Presenting a case of Anti-NMDA-receptor encephalitis that was observed at our hospital and the steps taken from its initial assessment by Psychiatry to the final diagnose and treatment by Neurology, our objective is to describe this disorder in order to make it known to the specialists in Psychiatry.
Methods
The case is that of a 14 year old girl who presents altered behavior, bizarre delusions and auditory hallucinations with subacute onset. In psychiatric assessment it is noted that the patient presents fever, slight and language impairment: Medical and Neurological assessment are requested. The steps followed to rule out other disorders are presented. SPECT and the detection of specific anti-NMDA-receptor antibodies in serum were necessary for an accurate diagnose.
Results
The detection of specific antibodies is necessary for the diagnose of Anti-NMDA-receptor encephalitis. NMDA receptors are ligand-gated cation channels with crucial roles in synaptic transmission and plasticity. Their alteration could be a pathogenic mechanism in disorders such as epilepsy, dementia and schizophrenia.
Conclusions
Anti-NMDA-receptor encephalitis is a recently described clinical entity that should be taken in consideration to rule out other causes of subacute onset psychiatric symptoms in young women and girls. Its well-defined set of clinical characteristics should become familiar to the specialists in Psychiatry.
