There is a growing interest in understanding the impact of duty hours and resting times on training outcomes and the well-being of resident physicians. Psychiatry resident’s duty hours in Spain comprise a regular working schedule of 37.5h per week and a minimum of 4 mandatory on-call shifts. The most recent duty hours regulations in Spain were transposed from the European Working Time Directive (EWTD). According to Spanish Law, doctors cannot work for more than 48h per week and need to have resting times per day (at least 12h), per week (at least 36h) as well as annual leave (at least a month). However, there is practically no data on this situation in psychiatry resident physicians.
Objectives
Our aim is firstly, to describe the number of shifts performed by psychiatry resident physicians in Spain. Secondly, to describe compliance with the daily and weekly rests compared to those set in national and European law. Finally, to analyse the difference by demographic variables (gender and year of residency), in both the number of on-call duty shifts and compliance with rests.
Methods
A descriptive cross-sectional study was designed through an online survey adapted from the existing literature. The target population were Spanish psychiatry resident physicians undergoing PGT who started their specialist training during the years 2018–2021. The survey was disseminated through the Spanish regional medical councils to all active psychiatry resident physicians by mail as well as through informal communication channels. The study was authorised by the Spanish Medical Organization’s General Assembly which is the highest ethical and deontological body of physicians in Spain.
Results
55 responses were obtained, of which 61.82% identified as females. The mean number of on-call shifts in the last 3 months was 14.05. This mean was highest in women 14,32 and in the cohort of 2020 15.46 (first year of residency). Among the resident physicians surveyed, 66.07% exceeded the 48h per week limit set by the EWTD and 7% of them did not rest after a 24-h on-call shift. Furthermore, 22% of respondents did not have a day-off after a Saturday on-call shift. The mean working hours when not resting after an on-call-shift were 7 hours. The comparison by gender and year of residency of the main variables can be seen in figures 1 and 2 respectively.

Conclusions
Psychiatry resident physicians in Spain greatly exceed the established 48 h/week EWTD limit. Likewise, non-compliance with labour regulations regarding mandatory rest after on-call duty and minimum weekly rest periods are observed. Differences can be seen by gender and year of residency. The situation described could potentially create a high-risk situation for the health and psychosocial well-being of resident physicians, hinder learning outcomes and could lead to suboptimal patient care.
Depersonalization/derealization encompasses a series of symptoms that are difficult to describe by the patient, as well as complex to diagnose by the professional, and can go through multiple diagnoses prior to the diagnosis of certainty.
Objectives
It is proposed, through a clinical case, to know the characteristics of this disorder, evolution, differential diagnosis and therapeutic possibilities
Methods
62-year-old male, history of harmful alcohol consumption and a previous admission to a psychiatric short hospitalization unit for self-injury (superficial cuts in the context of severe mental illness of his wife) post-transplantation who is required by ideas of death, anhedonia and lack of collaboration in patient, The day before the evaluation, refusal to take oral treatment, selective mutism. Pre-transplant evaluation where no psychopathological alteration was observed.
Results
What is initially assessed and treated as a confusional episode of inactive type, through a correct psychopathological examination and with subsequent continuous interviews, with mood fluctuations throughout the admission, is subsequently oriented as an acute stress disorder, adaptive reaction with an anxious-depressive component and finally concluding that we are facing a dissociative disorder, highlighting the depersonalization/derealization on a dysfunctional personality base.
Conclusions
Characteristic of depersonalization is the great difficulty in describing symptoms, the feeling of being disconnected from one’s own body, emotions and reality. The latest studies on etiopathogenesis with MRI show an inhibitory response on the limbic system by hyperactivation of the ventrolateral prefrontal cortex as well as a decrease in the autonomic response, the initial result being the attenuation of the processing of emotions. Among the differential diagnoses: post-anxiety illness disorder, major depressive episode, other dissociative disorders, panic disorder, psychotic disorder, substance-induced disorder There are several partially effective treatments, although the results so far are poor. SSRIs, quetiapine and naltrexone have been tried. Partial efficacy with lamotrigine together with SSRIs and, if high levels of anxiety coexist, SSRIs together with clonazepam. There are studies where psychodynamic psychotherapy, behavioral therapy and hypnosis have obtained partially effective results.
In recent years, there has been an increase in the prevalence of illicit use of fentanyl and other opioids in the United States population. This has led to an increase in medical, psychopathological and abuse-associated comorbidity, an increase in deaths and a decrease in the age of consumption, and has become a serious emerging problem in young people.
We present the case of an 18-year-old woman from the United States who recently settled in Spain and started a follow-up in Mental Health due to opioid and other substance abuse problems.
Objectives
To address the growing problem surrounding the illicit use of fentanyl and opioids as drugs of abuse based on the presentation of the clinical case mentioned above.
Methods
Bibliographic search and description of a clinical case of a patient under follow-up by Mental Health at the “Hospital Clínico Universitario de Valladolid”.
Results
An 18-year-old woman from the United States who has been living with her father in Spain since the summer of 2023, having moved to Spain due to problems related to substance abuse.
With no previous medical or surgical history and with a history of follow-up in Mental Health in her country of origin for depressive symptomatology, dysfunctional personality traits and abuse of different toxic substances since adolescence.
After a brief and erratic follow-up in Psychiatry for anxious-depressive symptoms reactive to a complex and conflictive relationship with his mother and marked academic difficulties during the first years of adolescence, at the age of 15 he started using cannabis and alcohol, thus beginning a period marked by relationships with marginalized sectors of the population, substance abuse and school failure.
As his cannabis consumption intensified, he began to consume fentanyl prescribed to his mother, as well as other opioids to which he had access illegally, for which reason he had to be admitted twice to detoxification centers without results, which is why his family finally decided to move him to Spain.
Conclusions
In recent years, fentanyl abuse has become a serious public health problem that is mainly centered in the young population.
High levels of impulsivity and lack of frustration tolerance predispose to the use of illicit substances for elusive purposes.
Substance abuse carries with it not only an important organic comorbidity, but also a marked socio-familial and economic repercussion.
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.
CADASIL (Cerebral Autosomal Dominant Arteriopathy with Subcortical Infarcts and Leukoencephalopathy) is a cerebrovascular disease, tht appears in 1.98/100,000. It´s caused by a mutation of the Notch3 gene and is characterized by accumulation of granular osmiophilic material in the middle layer of the small and median sized cerebral arteries.
Sypmtoms are migraine, recurrent cerebral ischemic episodes, dementia, neuropsychiatric disorders (anosognosia, character disorders, apathy and cognitive impairment). It usually appears between 30-60 years, although there is an important variability. There is no curative treatment, only palliative.
Objectives
Clinical review of anosognosia and its presence in CADASIL disease.
Methods
Clinical case and literatura review.
Results
We presented the clinical case of a 68-year-old man, who was diagnosed with CADASIL after a stroke 3 years earlier. In his family, his brother was diagnosed also with CADASIL. The patient had previously presented disturbances in impulse control (hyperorality) and important executive failures. He currently presented anosognosia, deficits in verbal memory, spatial perception and executive functions, in addition to behavioral alterations and apathy. Due to these deficits he was prohibited from certain activities (driving, hunting).
The patient was not aware of these deficits and becouse of his “no knowledge of his illness”, he disagreed with these prohibitions, so he showed rage and anger at the impotence of not understanding why certain actions are prohibited.
In the consultation, mnesic errors and in naming objects were also objectified, for which it was recommended to carry out cognitive stimulation on a daily basis. In addition, he presented failures of sphincter incontinence, especially of urine and occasionally also of the anal sphincter. He had previously had episodes of myoclonus or fasciculations.
A genetic study by massive sequencing confirmed the heterozygous presence of the pathogenic variant c.1819C>T p.(Arg607Cys) in the NOTCH3 gene, a CADASIL disease.
Conclusions
The anosognosia that many patients with CADASIL disease present constitutes a problem because it contributes to the delay in consultation and, therefore, the delay in the adequate diagnostic approach, therapeutic possibilities and family genetic counseling. Due in part to anosognosia, CADASIL is considered an underdiagnosed entity. Due to the lack of awareness and the consequent lack of recognition of the deficit, these people are often seen as stubborn and difficult to deal with by people in their immediate environment.
In addition, there is general difficulty in the rehabilitation process, since patients do not think the neccesity to be treated. This can generate frustration and despair both in their relatives and in the health personnel.
For all these reasons, both in anosognosia and in CADASIL disease, adequate psychological support is needed for both those affected and their families.
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.
Knowledge of frontal ablation from marine-terminating glaciers (i.e., mass lost at the calving face) is critical for constraining glacier mass balance, improving projections of mass change, and identifying the processes that govern frontal mass loss. Here, we discuss the challenges involved in computing frontal ablation and the unique issues pertaining to both glaciers and ice sheets. Frontal ablation estimates require numerous datasets, including glacier terminus area change, thickness, surface velocity, density, and climatic mass balance. Observations and models of these variables have improved over the past decade, but significant gaps and regional discrepancies remain, and better quantification of temporal variability in frontal ablation is needed. Despite major advances in satellite-derived large-scale datasets, large uncertainties remain with respect to ice thickness, depth-averaged velocities, and the bulk density of glacier ice close to calving termini or grounding lines. We suggest ways in which we can move toward globally complete frontal ablation estimates, highlighting areas where we need improved datasets and increased collaboration.
OBJECTIVES/GOALS: The Title V Coop developed CRESCO, a physical and virtual space in the libraries of the two cooperating institutions. Adopting a flexible and transformational approach, it offers services to support the development of research and information skills of undergraduate students and faculty who receive clinical-translational research (CTR) training. METHODS/STUDY POPULATION: Since 2016, CRESCO has been staffed by a multidisciplinary team composed of three librarians, a statistician, an instructional designer, and an IT specialist. The physical facilities of the two libraries were remodeled and equipped, and a central portal was created to provide services and access to resources on a 7/24 basis. Online tutorials, workshops, and mentoring services have been offered that address topics in statistics, literature search, plagiarism, and the use of several research software. Services statistics are collected, and a questionnaire is administered to evaluate the workshops. RESULTS/ANTICIPATED RESULTS: The main results include 12 online tutorials created in CTR areas and available in the CRESCO hub portal; 14,660 mentoring/consultations offered in statistics, the use of research-related software, and the search for scientific literature search; and 6 online workshops created in CTR areas, with 463 attendees. When evaluating online workshops, participants considered that their acquired learning was high or extremely high on the following topics: use of Intellectus Statistics (88%, n = 96); selection of statistical tests (81%, n = 92); use of Turnitin (85%, n = 76); literature search (91%, n = 58); and citations and references in Mendeley (90%, n = 67). DISCUSSION/SIGNIFICANCE: These results suggest that the flexible, multidisciplinary, and transformational approach of CRESCO has been successful in helping undergraduate students and faculty develop the skills necessary to conduct CTR projects.
The British Society for Parasitology (BSP) holds a biannual symposium devoted to the kinetoplastids, and seeks to cover the full gamut of research into these important organisms, and alternates with the Woods Hole Kinetoplastid Molecular Cell Biology meeting that serves a similar community. While normally embedded within the main BSP Spring meeting, on several occasions the symposium has enjoyed the opportunity of being hosted on mainland Europe. In 2020, the BSP was fortunate to spend some time in Granada in Spain, where a superb meeting with excellent science in a spectacular setting was overshadowed by news of an emerging novel coronavirus. In this editorial, we hope to have captured some of that excellent science and to highlight aspects of the many great papers and reviews in this special issue, as well as provide a few images from the meeting, which we hope for this who attended will bring back some fond memories.
To examine associations between household food insecurity and children’s physical activity and sedentary behaviours.
Design:
Secondary analysis was conducted on the Healthy Communities Study, an observational study from 2013 to 2015. Household food insecurity was assessed by two items from the US Department of Agriculture’s 18-item US Household Food Security Survey Module. Physical activity was measured using the 7-d Physical Activity Behaviour Recall instrument. Data were analysed using multilevel statistical modelling.
Setting:
A total of 130 communities in the USA.
Participants:
In sum, 5138 US children aged 4–15 years.
Results:
No associations were found for the relationship between household food insecurity and child physical activity. A significant interaction between household food insecurity and child sex for sedentary behaviours was observed (P = 0·03).
Conclusions:
Additional research capturing a more detailed assessment of children’s experiences of food insecurity in relation to physical activity is warranted. Future studies may consider adopting qualitative study designs or utilising food insecurity measures that specifically target child-level food insecurity. Subsequent research may also seek to further explore sub-group analyses by sex.
In strong electromagnetic regimes, gyrokinetic simulations have linked a substantial ion-scale turbulence stabilization to the presence of supra-thermal particles, capturing qualitatively well the experimental observations in different devices worldwide. An explanation for the underlying physical mechanism responsible for the fast-ion-induced turbulent transport reduction observed in the numerical simulations has been proposed only recently by Di Siena et al. (Nucl. Fusion, vol. 59, 2019, p. 124001; Nucl. Fusion, vol. 60, 2020, p. 089501). It involves a nonlinear cross-scale coupling (nonlinear interaction involving different modes at different wavenumbers) between ion-temperature-gradient and marginally stable Alfvén eigenmodes, which in turn increases zonal flow activity. In view of an optimization of this turbulence-stabilizing effect, the key parameters controlling the nonlinear cross-scale coupling are here identified. At the same time, these findings provide useful insights for reduced-turbulence models and integrative approaches, which might be trained on the results presented in this paper to grasp the underlying physics and the parameter scaling of the beneficial effects of fast particles on plasma turbulence.
Conflicting results have been obtained through meta-analyses for the role of obesity as a risk factor for adverse outcomes in patients with coronavirus disease-2019 (COVID-19), possibly due to the inclusion of predominantly multimorbid patients with severe COVID-19. Here, we aimed to study obesity alone or in combination with other comorbidities as a risk factor for short-term all-cause mortality and other adverse outcomes in Mexican patients evaluated for suspected COVID-19 in ambulatory units and hospitals in Mexico. We performed a retrospective observational analysis in a national cohort of 71 103 patients from all 32 states of Mexico from the National COVID-19 Epidemiological Surveillance Study. Two statistical models were applied through Cox regression to create survival models and logistic regression models to determine risk of death, hospitalisation, invasive mechanical ventilation, pneumonia and admission to an intensive care unit, conferred by obesity and other comorbidities (diabetes mellitus (DM), chronic obstructive pulmonary disease, asthma, immunosuppression, hypertension, cardiovascular disease and chronic kidney disease). Models were adjusted for other risk factors. From 24 February to 26 April 2020, 71 103 patients were evaluated for suspected COVID-19; 15 529 (21.8%) had a positive test for SARS-CoV-2; 46 960 (66.1%), negative and 8614 (12.1%), pending results. Obesity alone increased adjusted mortality risk in positive patients (hazard ratio (HR) = 2.7, 95% confidence interval (CI) 2.04–2.98), but not in negative and pending-result patients. Obesity combined with other comorbidities further increased risk of death (DM: HR = 2.79, 95% CI 2.04–3.80; immunosuppression: HR = 5.06, 95% CI 2.26–11.41; hypertension: HR = 2.30, 95% CI 1.77–3.01) and other adverse outcomes. In conclusion, obesity is a strong risk factor for short-term mortality and critical illness in Mexican patients with COVID-19; risk increases when obesity is present with other comorbidities.
The aim of this study is to test the psychometric properties of the Spanish validation of the Fear of COVID-19 Scale (FCV-19S) in a Paraguayan population.
Methods:
Participants were recruited through an Internet-based survey. All participants whose scores in the Hospital Anxiety and Depression Scale (HADS) and The Fear Questionnaire (FQ) were greater than zero were included. 1245 subjects responded voluntarily: 1077 subjects, scoring >0, were considered.
Results:
To establish construct validity of the FCV-19S, an exploratory factor analysis was performed using the KMO test, which was adequate, and the Bartlett sphericity test, which was significant (p <.0001). The CFI, NFI, GFI, TLI and RMSEA indices were used to evaluate the model and showed good adjustment. Cronbach’s α showed valid internal consistency (α = 0.86). This validation was supported by significant correlation (p <.001) with the HADS scale for anxiety and depression and with the FQ scale for specific phobia.
Conclusions:
The Spanish version of the FCV-19S is a 7-item scale with two dimensions, psychological symptoms and physiological symptoms, which demonstrated robust psychometric properties in a Paraguayan population.
Most of the existing prediction models for COVID-19 lack validation, are inadequately reported or are at high risk of bias, a reason which has led to discourage their use. Few existing models have the potential to be extensively used by healthcare providers in low-resource settings since many require laboratory and imaging predictors. Therefore, we sought to develop and validate a multivariable prediction model of death in Mexican patients with COVID-19, by using demographic and patient history predictors. We conducted a national retrospective cohort study in two different sets of patients from the Mexican COVID-19 Epidemiologic Surveillance Study. Patients with a positive reverse transcription-polymerase chain reaction for SARS-CoV-2 and complete unduplicated data were eligible. In total, 83 779 patients were included to develop the scoring system through a multivariable Cox regression model; 100 000, to validate the model. Eight predictors (age, sex, diabetes, chronic obstructive pulmonary disease, immunosuppression, hypertension, obesity and chronic kidney disease) were included in the scoring system called PH-Covid19 (range of values: −2 to 25 points). The predictive model has a discrimination of death of 0.8 (95% confidence interval (CI) 0.796–0.804). The PH-Covid19 scoring system was developed and validated in Mexican patients to aid clinicians to stratify patients with COVID-19 at risk of fatal outcomes, allowing for better and efficient use of resources.
Epidemiological studies indicate that individuals with one type of mental disorder have an increased risk of subsequently developing other types of mental disorders. This study aimed to undertake a comprehensive analysis of pair-wise lifetime comorbidity across a range of common mental disorders based on a diverse range of population-based surveys.
Methods
The WHO World Mental Health (WMH) surveys assessed 145 990 adult respondents from 27 countries. Based on retrospectively-reported age-of-onset for 24 DSM-IV mental disorders, associations were examined between all 548 logically possible temporally-ordered disorder pairs. Overall and time-dependent hazard ratios (HRs) and 95% confidence intervals (CIs) were calculated using Cox proportional hazards models. Absolute risks were estimated using the product-limit method. Estimates were generated separately for men and women.
Results
Each prior lifetime mental disorder was associated with an increased risk of subsequent first onset of each other disorder. The median HR was 12.1 (mean = 14.4; range 5.2–110.8, interquartile range = 6.0–19.4). The HRs were most prominent between closely-related mental disorder types and in the first 1–2 years after the onset of the prior disorder. Although HRs declined with time since prior disorder, significantly elevated risk of subsequent comorbidity persisted for at least 15 years. Appreciable absolute risks of secondary disorders were found over time for many pairs.
Conclusions
Survey data from a range of sites confirms that comorbidity between mental disorders is common. Understanding the risks of temporally secondary disorders may help design practical programs for primary prevention of secondary disorders.
