Objectives/Goals: We assessed the feasibility of using a large language model (LLM) to create lay language descriptions of study protocols for recruitment, which has the potential to improve accessibility and transparency of clinical studies and enable participants to make informed decisions. Methods/Study Population: All studies from a clinical research recruitment platform were included, which features human-written lay descriptions and titles for study recruitment. Corresponding protocol summaries in the IRB system were extracted and translated into lay language using a LLM (gpt-35-turbo-0613). A subset was used to develop prompt variations through an iterative process. Prompt strategies evaluated include chain-of-thought and few-shot prompting techniques. LLM-generated and human-written descriptions were compared for readability using Flesch–Kincaid and Simple Measure of Gobbledygook (SMOG) reading grade levels and information completeness using Word Movers’ Distance (WMD). Results/Anticipated Results: A total of 55 study descriptions were included – 10 were used to develop prompts and 45 were used for evaluation. The final LLM instructions included multistep prompts. The LLM was first instructed to produce a two- to three-sentence long description without using scientific jargon and included two pairs of examples. The LLM was then asked to shorten the description and finally to provide an engaging title. LLM-generated and human-written summaries were similar in length (median (IQR) 328 (278.5–360.5) vs. 342 (203–532.5) characters, respectively). LLM-generated summaries had lower Flesch-Kincaid grade level (5.15 vs. 8.28, p Discussion/Significance of Impact: An LLM can be used to generate lay language summaries that are readable at a lower grade level while maintaining semantic similarity. This approach can be used to improve the drafting of summaries for recruitment, thereby improving accessibility to potential participants. Future work includes human evaluation and implementation into practice.
Elder abuse (EA) often remains hidden, and many victims do not interact with formal systems. Concerned persons (CPs) are family, friends, and neighbours who play an essential role in supporting EA victims.
Objective
The aim of this study was to understand CPs’ role and help-seeking experiences.
Methods
Nineteen self-identified CPs shared their experience of being involved in an EA case via an interview and/or survey, with responses analysed qualitatively.
Findings
CPs were primarily the victims’ female relatives, often related to the perpetrator, and had sought help from a wide range of formal and informal sources, facing many barriers in protecting victims from harm. Challenges commonly related to formal services and EA perpetrators. Through knowing about the abuse and/or seeking help, participants experienced negative impacts, particularly psychological ones.
Discussion
Findings suggest that CPs can play a key role in supporting EA victims but require further support and recognition from services to fulfil this role.
Previous studies have shown that helminth infection protects against the development of diabetes mellitus (DM), possibly related to the hygiene hypothesis. However, studies involving Stronglyoides stercoralis and its possible association with DM are scarce and have shown contradicting results, prompting us to perform this meta-analysis to obtain more precise estimates. Related studies were searched from PubMed, Google Scholar, Science Direct, and Cochrane Library until 1 August 2024. Data on the occurrence of DM in patients positive and negative for S. stercoralis were obtained. All analyses were done using Review Manager 5.4. The initial search yielded a total of 1725 studies, and after thorough screening and exclusion, only five articles involving 2106 participants (536 cases and 1570 controls) were included in the meta-analysis. Heterogeneity was assessed, and outlier studies were excluded using a funnel plot. Results showed a significant association of S. stercoralis infection with DM, suggesting that those with the infection are less likely to develop DM. Overall, the results suggest that S. stercoralis infection may decrease the likelihood of developing DM, potentially supporting the hygiene hypothesis.
The New Jersey Kids Study (NJKS) is a transdisciplinary statewide initiative to understand influences on child health, development, and disease. We conducted a mixed-methods study of project planning teams to investigate team effectiveness and relationships between team dynamics and quality of deliverables.
Methods:
Ten theme-based working groups (WGs) (e.g., Neurodevelopment, Nutrition) informed protocol development and submitted final reports. WG members (n = 79, 75%) completed questionnaires including de-identified demographic and professional information and a modified TeamSTEPPS Team Assessment Questionnaire (TAQ). Reviewers independently evaluated final reports using a standardized tool. We analyzed questionnaire results and final report assessments using linear regression and performed constant comparative qualitative analysis to identify central themes.
Results:
WG-level factors associated with greater team effectiveness included proportion of full professors (β = 31.24, 95% CI 27.65–34.82), team size (β = 0.81, 95% CI 0.70–0.92), and percent dedicated research effort (β = 0.11, 95% CI 0.09–0.13); age distribution (β = −2.67, 95% CI –3.00 to –2.38) and diversity of school affiliations (β = –33.32, 95% CI –36.84 to –29.80) were inversely associated with team effectiveness. No factors were associated with final report assessments. Perceptions of overall initiative leadership were associated with expressed enthusiasm for future NJKS participation. Qualitative analyses of final reports yielded four themes related to team science practices: organization and process, collaboration, task delegation, and decision-making patterns.
Conclusions:
We identified several correlates of team effectiveness in a team science initiative's early planning phase. Extra effort may be needed to bridge differences in team members' backgrounds to enhance the effectiveness of diverse teams. This work also highlights leadership as an important component in future investigator engagement.
TwinsMX registry is a national research initiative in Mexico that aims to understand the complex interplay between genetics and environment in shaping physical and mental health traits among the country’s population. With a multidisciplinary approach, TwinsMX aims to advance our knowledge of the genetic and environmental mechanisms underlying ethnic variations in complex traits and diseases, including behavioral, psychometric, anthropometric, metabolic, cardiovascular and mental disorders. With information gathered from over 2800 twins, this article updates the prevalence of several complex traits; and describes the advances and novel ideas we have implemented such as magnetic resonance imaging. The future expansion of the TwinsMX registry will enhance our comprehension of the intricate interplay between genetics and environment in shaping health and disease in the Mexican population. Overall, this report describes the progress in the building of a solid database that will allow the study of complex traits in the Mexican population, valuable not only for our consortium, but also for the worldwide scientific community, by providing new insights of understudied genetically admixed populations.
One of the biggest challenges for primary care professionals is to know when it is appropriate to request a consultation with a psychiatrist. A complete medical history should be performed to detect anxious-depressive symptoms, as well as to determine the intensity, the trigger, time of evolution, and the functional repercussion (1). It is also important that the patient is able to express his or her symptoms and ask for help. The concept of “Alexitimia” refers to the difficulty of expressing feelings verbally, and is a frequent symptom in depressive patients (2).
In mild cases and with little repercussion, the physician himself can initiate treatment and follow up (3). However, on other occasions, it will be advisable to request a consultation with psychiatry.
Objectives
The main objective is to observe the time that elapses from the onset of symptoms until consultation with the Mental Health team is finally requested. Some preliminary results can already be obtained from this data collection.
Methods
We have decided to carry out a descriptive study, collecting different variables from patients attending a first Psychiatry consultation.
Results
In a total sample of 208 patients, the majority (67%) were between 31 and 60 years old. Following the DSM-V criteria (4), patients were classified into groups according to their disorder: Adaptive, depressive, or other. These data were cross-referenced (Figure 1).
Subsequently, the time elapsed from the onset of symptoms (referred by the patients) was collected, until the referral to Psychiatry was processed. In order to make a comparison, average time (in days) was calculated for the different groups according to their age and diagnosis.
Those patients under 30 years were referred to psychiatry later. A downward trend was seen as the age range increased. In the “younger than 30” and “between 31 and 60” groups, patients who met criteria for Depressive Disorder took longer to be referred, which was striking considering that they are usually considered as more severe patients (Figure 2). This can be attributed to a greater difficulty in expressing their emotions (alexithymia), as another depressive symptom. Disaggregating these data by gender, the patients who clearly took the longest to be referred were men under 30 years old with a final diagnosis of Depressive Disorder (Figure 3). This gender difference is consistent with the social impact of alexithymia according to some articles (5).

Conclusions
It is important that primary care physicians know how to take a complete history in those patients with symptoms of anxiety and depression.
In many cases, patients themselves have difficulties expressing their emotions and feelings (alexithymia), which may be another symptom of their discomfort.
This may lead to a delay in the time until referral to a psychiatry is requested, and therefore a worsening of symptoms.
The use of antipsychotics (APS) is essential. Despite their great efficacy, some of them are associated with an increase in prolactin levels that can lead to hormonal changes needing to be identified and managed [1,2,3]. Hormonal changes use to have clinical implications including hypogonadism, infertility and sexual dysfunction
Objectives
To evaluate possible hormonal alterations and some clinical implications produced by hyperprolactinemia (HPRL) derived from the use of some antipsychotic compounds.
Methods
A complete fasting blood test was performed on a sample of 113 subjects (69 men and 44 women). 54% (n = 61) showed a normal prolactin level and 46% (n = 52) showed hyperprolactinaemia ( >50ng / ml). On the global sample, 39.8% (n = 45) was treated with some hyperprolactinemic drug , mostly risperidone and paliperidone.
Results
Some differences were found depending on the gender of the subjects. A highly significant inverse relationship between the values of prolactin and testosterone was found in males (p=0.020, r=-0.285). In females, increased prolactin level was significantly related to decreased cortisol values.
Conclusions
Antipsychotic-related Hyperprolactinaemia ( mainly risperidone and paliperidone) is related with a decrease in testosterone levels in males and with an increase in cortisol levels in females.
Psychiatric illnesses are related with a reduced life expectancy and an increase of mortality rates (around 60%) mainly associated with cardiovascular diseases [1]. The high prevalence of obesity, metabolic syndrome, diabetes mellitus and tobacco use among these patients undoubtelly predispose to the impairment in physical health and mortaility increase. Regular physical activity in the general population is associated with a decrease in cardiovascular risk but litle is know about iss influence in some chronic and severe mental disorders like schizophrenia [2].
Objectives
To quantify the physical activity performed by a sample of subjects with psychosis, borth males and female, compared to a control group.
Methods
A sample composed of 141 patients with schizoprenia was compared to 103 healthy subjects as a control group. The International Physical Activity Questionnaire - Short Form (IPAQ) scale was applied to all participants. The time (minutes) of physical activity performed in a week (METs) was collected by each participant [3].
Results
The differences in the total physical activity Mets for the patients with schizophrenia were highly significant (p = 0.001), showing a lower degree of physical activity compared to the control group. A higher and significant percentage of sedentary lifestyle among the psychiatric group (64.5%), compared to 35.5% in the control group was found.
Conclusions
The group of pateints with Schizophrenia showed a significant higher sedentary lifestile including less physical activity. This finding could be highly related with a higher risk of cardiovascular disease and deterioration of the physical health.
One of the most important aspects of genetic evaluation (GE) is the definition of contemporary groups (CG), commonly defined as animals of the same sex born in the same herd, year and season. The objective of this study was to use an aridity index (AI) to classify season and evaluate the implications on the GE of Braunvieh cattle. A data set with 32 777 and 22 448 birth weight (BW) and weaning weight adjusted to 240 days (WW) records, respectively, was used to compare two methods of classification of climatic seasons to be used in the definition of CG for GE models. The first method considered rain season criterion (RC), and the second method is a proposed classification using an AI. Both methods were compared using two approaches. The first approach examined differences in mixed models using the RC and AI season to select the best model for BW and WW, evaluated by different goodness of fit measures. The second approach considered fitting a GE model including the season classifications into the CG structure. Lower probability values for season effect and better goodness of fit measures were obtained when the season was classified according to the AI. Results showed that although differences are small, the AI allows a better model fitting for live-weight traits than RC and revealed a re-ranking effect on expected progeny differences data. Further analysis with other traits would demonstrate the extended utility of AI indicators to be considered for fitting models under a climatic change environment.
This paper presents a methodology that permits to automate binary classification using the minimum possible number of attributes. In this methodology, the success of the binary prediction does not lie in the accuracy of an algorithm but in the evaluation metrics, which give information about the goodness of fit; which is an important factor when the data batch is unbalanced. The proposed methodology assesses the possible biases in identifying one algorithm as the best performer when considering the goodness of fit of an algorithm through evaluation metrics. The dimension of data has been reduced through the cumulative explained variance. Then, the performance of six machine learning classification models has been compared through Matthew correlation coefficient (MCC), area under curve – receiver operating characteristic (ROC-AUC), and area under curve – precision-recall (AUC-PR). The results show graphically and numerically how the evaluation metrics interfere with the most optimal outcome of an algorithm. The algorithms with the best performance in terms of evaluation metrics have been random forest and gradient boosting. In the imbalanced datasets, MCC has provided better prediction results than ROC-AUC or AUC-PR. The proposed methodology is adapted to the case of bankruptcy prediction.
We know the coexistence of traumatic factors (loss of affective relationships, experiences of abuse, extreme risk situations, etc.) is common in psychiatric pathologies in which level of stress experienced exceeds normal capacity of the person, favoring the appearance of dissociative or excision mechanisms. A common mistake is to pathologize them and try to eliminate them.
Objectives
The objective of this paper is to study trauma and defense mechanisms involved, in order to carry out a better approach.
Methods
A bibliographic search was performed from different database (Pubmed, TripDatabase) about trauma, mechanisms involved and the construction of identity.
Results
We know neural pathways mature asymmetrically in evolutionary development (functions related to attention, concentration and executive function having special importance) and thus, traumas occurred in moments of greatest vulnerability such as early childhood, can damage and interfere with the correct integration of neural processes, producing disproportionate and unnecessarily maintained alert responses (common basis for many pathologies such as borderline personality disorder or traumatic psychosis). In response to this, reactive mechanisms are produced (such as dissociation or cleavage) that are not necessarily pathological and therefore, we should not always intervene by eliminating them because they often function as a protective factor, allowing to preserve functioning and favoring recovery.
Conclusions
In conclusion, we need a better understanding of mechanisms involved in trauma, executive function and the alarm system beyond anxiety reactions, trying to understand the function of symptom without eliminating it, but evaluating whether there are healthier alternatives can be promoted for the complete recovery of the patient.
Thanks to advances in medicine, more diseases are being cured, but this benefit can become a problem when it causes a worsening of quality of life.
Objectives
The objective of this paper is to analyze, regarding the following case, the convenience of treating or to limit the therapeutic effort (LTE) in psychiatric patients who are in situations at the end of life.
Methods
62-year-old woman begins with depressive symptoms from financial problems. In 4 months ago she makes four suicide attempts (drug overdose, cuts, self-stabbing, and precipitation), being hospitalized in ICU after latter because of multiple trauma and shock. During that time, she had a bad evolution with several complications that made LTE be evaluated. A bibliographic search was performed from different database (Pubmed, TripDatabase) about LTE and ethical implications.
Results
Trying to prolong life by disproportionate means in a patient with a poor prognosis or poor quality of life is bad practice. We must assess the severity, quality of life, capacity and preferences of the patient to decide to treat or not, thus guaranteeing the principle of beneficence. It is also important to respect the principle of autonomy, accepting patients can refuse treatment. All this is equally applicable to psychiatric patients, whom we should not stigmatize but rather evaluate their ability to decide, as in any person.
Conclusions
In conclusion, in situations of high suffering and near death, it is necessary a complete evaluation of the patient (psychiatric or not) is carried out in order to act in the most ethical way.
There are many authors that follow and develop Pinel-hypotheses about unitary psychosis, joining recent discoveries in neuropathology and neurochemistry, supporting the vision of mental illness as neurodevelop disorders. The classification they suggest, distinguishes early, late neurodevelop disorders, and those related to traumatic factors, what determine an evolutive vision of this pathology. In terms of anxiety symptoms/disorders, they have been usually associated with categorical pathology, and treated focus on symptoms,unfortunately relapses are very frequent.
Objectives
Proving that the evolutive vision may ease a change on the intervention of anxiety disorders, that would propound different therapeutic alternatives.
Methods
A bibliographic search was performed from different databases, showing throw aspects related to main etiopathogenic theories about anxiety disorders from an evolutive vision.
Results
Evolutive-Psychology raises that anxiety is a concomitant process to development, that grows progressively and is necessary to induce changes in it. However a high level of anxiety might block that process or causes alterations. In that sense, anxiety-disorders may be related to an excess of anxiety that provoke a fault in present handling mechanisms. According to classic dynamic-theories, these mechanisms are associated with defence concept, but now we can link them to neurobiological development. From this point, there exists an asymmetric neurological maturation through childhood-adolescence that translates different manifestations of anxiety along development, initially more related with external contemption and relationship with caregiver, but later with hormonal pulses, physical changes and separation from family.
Conclusions
The evolutive vision allows to understand development fluctuation of anxiety symptoms along the growth process, more accurately than categorical classic tendency.
Concomitant presence of obsessive-compulsive symptoms(OCS)is relatively frequent in psychotic patients and there are different hypotheses trying to explain the origin of them as pathology evolution,comorbid disorder,defence mechanism,or even a medication side-effect,but it is difficult to make a precise evaluation of these symptoms and the mechanisms involved.SometimesOCS are the first manifestation toappear without any other areas affected,and psychotic disorder comes later with initial symptoms in that domain.
Objectives
Evaluate the association between OCS and psychosis to document pathogenia of both entities.
Methods
A bibliographic search was performed about this topic.We present two cases of patients that have been referred to our unit: A34year old man, a usual consumer of cannabis,who shows checking and organizing compulsions that interfere significantly with their life.Consumptions grew progressively until they became daily,trying to decrease partly this behaviour. He comes to an addiction unit where he achieves abstinence,but immediately shows an important functional-impairment, adding to the previous compulsions new ones,and also thought blocking,social retraction and personality change. He starts taking antidepressant and benzodiazepines to reduceOCS, and weeks later begins a manic episode with delusions as a bipolar-disorder debut. A29year old man, with a history of familiar obsessive personality,that begins to worry about physical appearance and starts compulsive behaviour focused on exercise preventing him from daily activities.No response to antidepressants, he started antipsychotics and develop referential-symptoms.
Results
Both are atypical presentations of bipolar and schizophreniform disorders withOCS,where the beginning of treatment causes psychosis-symptoms not previously developed.
Conclusions
Frequent doubts are what factors determine the eclosion.The triggers are not clear and neither the related-pathology.
Most mental disorders tend to relapse (severe or mild pathologies such as anxiety or dystima disorders), which are potentially recoverable and yet, tend to evolve poorly, persisting residual symptoms without achieving a complete recovery.
Objectives
The objective of this paper is to analyze the factors that influence process of recurrence and chronification, among which are our own therapeutic interventions.
Methods
A bibliographic search was performed from different database (Pubmed, TripDatabase) about the iatrogenic potential of our intervention (psychopharmacological or psychotherapeutic), analyzing influence and mechanisms involved, and the way to prevent them.
Results
Anxiety is a necessary element for the development of people, both from a biological perspective (natural and adaptive psychological response that allows us to respond adequately to possible threats); as an evolutionary psychological (element involved in conflict resolution, in turn necessary for personal development). It would be a mistake to consider it as pathological and try to eliminate it through medication or psychotherapy, since we could interfere with the natural recovery processes, contributing to its chronification and preventing possibility of change. At times, anxiety can be pathological when it occurs disproportionately and exceeds ability to adapt, but we must not eliminate it but to study origin and factors involved, to achieve complete resolution.
Conclusions
In conclusion, we must consider possible iatrogenesis of our therapeutic interventions in process of chronification of mental disorders and try to avoid them by adequately studying individual factors and characteristics, before intervening.
In order to understand etiopathogeny of any mental illness, it is important to be aware of the sequential emergence of symptoms, having presentations, that appear before, after or simultaneously. We could understand mental pathology as the sumatory of different factors and vulnerable cerebral substrates. Adverse external factors influence over them, causing relapses, that would lead to the evolution of diagnosis through time. However,patients usually come when pathology is already developed. Interventions are delayed, what is insufficient to modify the course of the illness.
Objectives
Proving that replacing classic clinical evaluation by an open access/multiintervention model, would determine a better prevention and reduction of relapse tendency.
Methods
We have arranged a prospective descriptive study of 124 users along 2 years. The idea was to test a first sample which let us check the viability of our project. We adopted a qualitative approach, linking practice and research, which have implied to perform a structured clinical process based on a dynamic reevaluation performed for different professionals in various stages using Rodman’s model.
Results
MultiIntervention model reduces the prognosis factor of delayed treatment thanks to reaching a high risk group in the early stages. That model allows us to determine the way each factor relates to each other, what facilitates multiple-intervention that tries to eliminate the symptom and also the relapse.
Conclusions
Late adolescence and early adulthood are stages in which many mental disorders start, however treatment delays some years. Rothman’s model may be a useful tool, what means a multiintervention treatment that mixes biological and psychosocial interventions.
SARS-CoV-2 is having an important direct impact, and also due to treatments used such as corticosteroids. Among its effects, we have focused on psychosis.
Objectives
The objective of this paper is to study, from following case, incidence of steroid-induced psychosis in context of COVID-19.
Methods
A bibliographic search was performed from different database (Pubmed, TripDatabase) about psychiatric symptoms associated with use of corticosteroids during pandemic. 64-year-old woman with no psychiatric history, who is hospitalized for pneumonia secondary to SARS-Cov2 and treated with antibiotics, bronchodilators, and corticosteroids. At 4 days she began with injury and nihilistic delusions. The corticosteroids were progressively reduced, adding 2.5 mg Risperidone, resolving after ten days.
Results
Corticosteroids are currently being used to treat the systemic inflammatory response associated with COVID-19, but they can produce other effects such as psychiatric symptoms (3-6%): 75% affective (mainly hypomanic symptoms); and 25% psychotic. Steroid-induced psychosis are characterized by confusion, delusions, and hallucinations, and they usually begin 3-4 days after onset, and resolve within a week. They are associated especially with oral systemic steroids and high doses: 1.3% with 40mg of prednisone, and 18% with 80mg; increased this incidence due to the greater use that is being made to treat COVID-19 and the higher doses used in severe cases (up to 120 mg).
Conclusions
To conclude, we need to know characteristics of these episodes in order to be able to prevent and treat them properly (minimum effective dose and less time), since they will probably occur more frequently at this time.
Branched-chain amino acids (BCAA) are considered markers of insulin resistance (IR) in subjects with obesity. In this study, we evaluated whether the presence of the SNP of the branched-chain aminotransferase 2 (BCAT2) gene can modify the effect of a dietary intervention (DI) on the plasma concentration of BCAA in subjects with obesity and IR. A prospective cohort study of adult subjects with obesity, BMI ≥ 30 kg/m2, homeostatic model assessment-insulin resistance (HOMA-IR ≥ 2·5) no diagnosed chronic disease, underwent a DI with an energy restriction of 3140 kJ/d and nutritional education for 1 month. Anthropometric measurements, body composition, blood pressure, resting energy expenditure, oral glucose tolerance test results, serum biochemical parameters and the plasma amino acid profile were evaluated before and after the DI. SNP were assessed by the TaqMan SNP genotyping assay. A total of eighty-two subjects were included, and fifteen subjects with a BCAT2 SNP had a greater reduction in leucine, isoleucine, valine and the sum of BCAA. Those subjects also had a greater reduction in skeletal muscle mass, fat-free mass, total body water, blood pressure, muscle strength and biochemical parameters after 1 month of the DI and adjusting for age and sex. This study demonstrated that the presence of the BCAT2 SNP promotes a greater reduction in plasma BCAA concentration after adjusting for age and sex, in subjects with obesity and IR after a 1-month energy-restricted DI.
