This paper presents the design and experimental validation of a robust flight control strategy for quadrotor unmanned aerial vehicles (UAVs) based on the Interconnection and Damping Assignment Passivity-Based Control (IDA-PBC) methodology. The proposed approach is specifically tailored to the Parrot Bebop 2, a commercial UAV. The IDA-PBC control law is derived using the Hamiltonian model of the UAV dynamics obtained from experimental data to represent the dynamics of all six degrees of freedom, including translational and rotational motions. The control strategy was validated through numerical simulations and experimental tests conducted in an indoor flight setup using MATLAB, Robot Operating System, and an OptiTrack motion capture system. Numerical and experimental results demonstrate that the controller effectively tracks desired flight trajectories, ensuring stable and robust performance.
Physical activity is a known protective factor against depression but physical activity competes with other time-consuming behaviors that may increase depression risk. This study investigates the association between time spent in various movement-related activities and incident major depression, with a particular focus on the effects of replacing TV-watching time with other activities. Additionally, we explored whether the impact of substituting TV-watching differs across age groups.
Methods
A population-based cohort study (Lifelines) with four-year follow-up, including 65,454 non-depressed adults (18+). Participants self-reported time spent in active commuting, leisure, sports, household, work or school physical-related activities, TV-watching, and sleep. Major depressive disorder was assessed using the Mini International Neuropsychiatric Interview. Compositional isotemporal data analysis was performed to analyze the effect of reallocating time in TV-watching with other activities adjusting for potential confounders. Interactions with age groups were also examined.
Results
The incidence of major depressive disorder was 2.4%. Reallocating TV-watching time to any other physical activity or sleep reduced this risk in middle-aged adults. In older adults, only substituting TV-watching time with sports reduced the probability of becoming depressed. No significant reduction in probabilities for incident depression was found in younger adults.
Conclusion
Replacing TV-watching time with other activities, including sleep, may serve as a preventive strategy against depressive disorder in middle-aged adults, while only the substitution with sports seems beneficial for older adults. Future research should aim to identify other activities, particularly in younger adults, that may prevent depression.
Haemosporidians constitute a monophyletic group of vector-borne parasites that infect a wide range of vertebrate hosts, including Neotropical lizards. The remarkable diversity of these host-parasite associations and inadequate research on certain parasite groups have resulted in controversial haemosporidian taxonomy. Herein, we rediscover erythrocytic and non-erythrocytic haemosporidians infecting golden tegus (Tupinambis teguixin) from Brazil and Colombia. The erythrocyte-inhabiting parasite belongs to Plasmodium sp., and the non-erythrocytic form was identified as Saurocytozoon tupinambi, previously attributed to the Family Leucocytozoidae. These non-pigmented haemosporidian parasites do not multiply in the blood. The relationships between the Saurocytozoon and Leucocytozoidae species were discussed for many years, especially during the 1970s. However, cytochrome b (cytb) sequences and the mitochondrial genomes recovered for this species strongly support classifying this parasite as a Plasmodium taxon. Therefore, we proposed a new combination for this parasite, Plasmodium (Saurocytozoon) tupinambi comb. nov., where Saurocytozoon is retained as a subgenus due to its distinct morphology. These results reinforce that a broader definition of Plasmodiidae must include saurian parasites that develop non-pigmented leucocytozoid-like gametocytes.
Metal pollution is a major global issue in aquatic environments, affecting environmental quality and potentially altering host–parasite dynamics. This study evaluates the buffering role of a larval trematode Himasthla sp. under experimental conditions to test the effect of copper (Cu) exposure on the survival of the marine snail Echinolittorina peruviana. Snails were collected from intertidal rocky pools over a two-month period from Coloso (23°45’S, 70°28’W), northern Chile, and identified as parasitized or unparasitized. Both groups were then exposed to Cu concentrations (3 and 6 mg/L). Kaplan–Meier curves were used to determine the percentage of survival over time and the respective confidence intervals (CI). A nested ANOVA was conducted to assess whether rediae abundance per snail varied by experiment time, snail status, and Cu concentration. Snail survival was affected by both Cu-concentrations, but the effect was greater at 6 mg/L. At 3 mg/L, 57% (CI: 49.9–66.6%) of unparasitized snails were alive at 192 h, while 56% (CI: 46.6–67.4%) of parasitized snails survived at 216 h. At 6 mg/L, 42% (CI:35-51%) of unparasitized snails survived at 192 h, while 48% of parasitized snails survived at 216 h (CI:39-59%). Regardless of Cu concentration, after 240 h, all unparasitized snails had died, while 15% of parasitized snails remained alive. Dead snails harboured 125±53 rediae, while survivors had 194±73 rediae, with no significant differences between treatments. Our results show that parasitized snails survived longer than unparasitized snails, suggesting a trade-off between parasitism and host survival in polluted environments.
Antibiograms monitor antibiotic resistance trends and help guide empiric antibiotic treatment. A statewide pediatric antibiogram can help inform stewardship efforts.
Methods:
Annual pediatric antibiograms for the five children’s hospitals in Georgia from 2014–2023 were collected. All sites used the Clinical and Laboratory Standards Institute guidelines for antibiogram development. Antibiogram data were combined, and the most common bacteria were included: Staphylococcus aureus, Streptococcus pneumoniae, Enterococcus faecalis, Escherichia coli, Klebsiella pneumoniae, Enterobacter cloacae complex and Pseudomonas aeruginosa. Interhospital differences were compared for methicillin-susceptible S. aureus (MSSA), methicillin-resistant S. aureus (MRSA), E. coli and K. pneumoniae. The combined data from 2014 and 2023 were compared to demonstrate antibiotic susceptibility changes over time.
Results:
Data in 2023 for MSSA and MRSA showed clindamycin susceptibility was 78% and 82%, respectively. S. pneumoniae susceptibility to amoxicillin/clavulanate was 96%. E. faecalis resistance to ampicillin and vancomycin was rare. For all included gram-negative bacteria, susceptibility remained high to 3rd generation cephalosporins (90%–92%) and meropenem (95%–99%). From 2014 to 2023, the rate of MRSA decreased from 49% to 33.5%. S. pneumoniae susceptibility to amoxicillin/clavulanate and clindamycin significantly increased. For E. coli, there was a significant decrease in susceptibility for cefazolin (90% to 84%), ceftriaxone (95% to 92%), and meropenem (100% to 99%). There were nonsignificant decreases in susceptibility for K. pneumoniae.
Conclusion:
Over the past 10 years, MRSA rates decreased, S. pneumoniae antibiotic susceptibility increased, and gram-negative bacilli susceptibility was stable to slightly decreased. Georgia antibiogram data support the recommended antibiotic treatment for common pediatric infections.
To develop and evaluate the validity and reliability of the Street Food and Beverage Tool (SFBT).
Design:
This methodological study contains two phases: (a) tool development, which involves conducting a systematic review followed by expert evaluation of the items, the creation of a nutritional healthfulness index (NH), and pilot testing; and (b) evaluation of the Tool’s Validity and Reliability. Content validity was judged by an external technical group, which evaluated the adequacy and pertinence of each tool item. Construct validity was evaluated around schools by testing the hypothesis: In high-income areas, there will be greater availability of healthy food and beverages at street food outlets (SFO), as measured by the NH index. Inter-rater and test–retest reliabilities were assessed outside subway stations. Pearson’s correlation, Cohen’s kappa and Content validity Indexes were used for reliability and validation. A multinomial regression model was used to estimate construct validity.
Setting:
Mexico City, Mexico.
Participants:
80 SFO at subway station exits and 1066 around schools from diverse income areas.
Results:
The SFBT content validity index was satisfactory. The construct validity of the NH index indicated higher values in higher-Social Development Index areas. The NH index showed a positive linear correlation between raters and across the first and second evaluations. The majority of item availability (>60 %) showed moderate to strong kappa values for inter-rater and test–retest reliability.
Conclusions:
The SFBT is a reliable and valid tool for assessing the availability of foods and beverages. Compared to other tools, it can measure the nutritional quality of SFO expressed as an NH index.
Latinx populations are underrepresented in clinical research. Asking Latinx research participants about their research experiences, barriers, and facilitators could help to improve research participation for these populations.
Methods:
The Salud Estres y Resilencia (SER) Hispano cohort study is a longitudinal cohort study of young adult Latinx immigrants whose design and conduct were tailored for their study population. We administered the Research Participant Perception Survey (RPPS) to SER Hispano participants to assess their experiences in the study. We describe overall results from the RPPS and compare results of surveys administered to SER Hispano participants via email versus telephone.
Results:
Of 340 participants who were contacted with the RPPS, 142 (42%) responded. Among respondents, 53 (37%) responded by initial email contact; and 89 (63%) responded by subsequent phone contact. The majority of respondents were between 35 and 44 years of age (54%), female (76%), and of Cuban origin (50%). Overall, research participants expressed high satisfaction with their research experience; 84% stated that they would “definitely” recommend research participation to friends and family, with no significant difference by method of survey administration (P = 0.45). The most common factor that was chosen that would influence future research participation was having summary results of the research shared with them (72%).
Conclusion:
We found that culturally tailored studies can be good experiences for Latinx research participants; and we found that use of the RPPS can be administered successfully, particularly when administered by more than one method, including telephone, to evaluate and to improve research experiences for this population.
From early on, infants show a preference for infant-directed speech (IDS) over adult-directed speech (ADS), and exposure to IDS has been correlated with language outcome measures such as vocabulary. The present multi-laboratory study explores this issue by investigating whether there is a link between early preference for IDS and later vocabulary size. Infants’ preference for IDS was tested as part of the ManyBabies 1 project, and follow-up CDI data were collected from a subsample of this dataset at 18 and 24 months. A total of 341 (18 months) and 327 (24 months) infants were tested across 21 laboratories. In neither preregistered analyses with North American and UK English, nor exploratory analyses with a larger sample did we find evidence for a relation between IDS preference and later vocabulary. We discuss implications of this finding in light of recent work suggesting that IDS preference measured in the laboratory has low test-retest reliability.
Lack of sexual orientation and gender identity (SOGI) data creates barriers for lesbian, gay, bisexual, transgender, and queer (LGBTQ+) people in health care. Barriers to SOGI data collection include physician misperception that patients do not want to answer these questions and discomfort asking SOGI questions. This study aimed to assess patient comfort towards SOGI questions across five quaternary care adult congenital heart disease (ACHD) centres.
Methods:
A survey administered to ACHD patients (≥18 years) asked (1) two-step gender identity and birth sex, (2) acceptance of SOGI data, and (3) the importance for ACHD physicians to know SOGI data. Chi-square tests were used to analyse differences among demographic groups and logistic regression modelled agreement with statement of patient disclosure of SOGI improving patient–physician communication.
Results:
Among 322 ACHD patients, 82% identified as heterosexual and 16% identified as LGBTQ+, across the age ranges 18–29 years (39.4%), 30–49 years (47.8%), 50–64 years (8.7%), and > 65 years (4.0%). Respondents (90.4%) felt comfortable answering SOGI questions. Respondents with bachelor’s/higher education were more likely to “agree” that disclosure of SOGI improves patient–physician communication compared to those with less than bachelor’s education (OR = 2.45; 95% CI 1.41, 4.25; p = .0015).
Conclusion:
These findings suggest that in this largely heterosexual population, SOGI data collection is unlikely to cause patient discomfort. Respondents with higher education were twice as likely to agree that SOGI disclosure improves patient–physician communication. The inclusion of SOGI data in future studies will provide larger samples of underrepresented minorities (e.g. LGBTQ+ population), thereby reducing healthcare disparities within the field of cardiovascular research.
Long-term care facilities, such as nursing homes and other assisted living facilities, have been hit particularly hard by the COVID-19. The overall pandemic created an enormous pressure on long-term care workers (LTCWs), making them particularly vulnerable to mental disorders. However, most of the existing evidence regarding the well-being of care professionals has predominantly focused on frontline healthcare workers.
Objectives
This study aimed to identify long-term psychological needs of LTCWs derived from the COVID-19 pandemic, as part of a project that is developing an intervention to reduce psychological distress in this population group.
Methods
We performed a qualitative study with a rapid research approach. Participants were recruited from long-term care facilities located in Catalonia, Spain. Between April and September 2022, we conducted semi-structured interviews inquiring about the most psychologically challenging stages of the pandemic, perceived emotions during those stages, main determinants of those emotions, and their emotional state at the time of the interview. We used a qualitative content analysis method with an inductive-deductive approach.
Results
Thirty LTCWs participated in the study. Mean age was 44 (SD=11,4), 87% were females and one third were from foreign nationalities. The period of the pandemic with highest mental health burden was the outbreak, with almost every worker having experienced some form of emotional distress. Emotional distress persisted over time in more than half of participants, with fatigue and nervousness being the main emotions expressed at the time of the interview. High workload, feeling that pandemic times are not over and poor working conditions that have remained since then, have been the most frequently expressed determinants of such emotions.
Conclusions
Long after the pandemic outbreak, emotional distress is still relevant. The persistent burden of psychological distress points to a need for institutions to take action to improve working conditions and promote employees’ wellbeing.
Empathy is an essential skill in the doctor-patient relationship since it contributes to improve aspects of health care and patient satisfaction. Nevertheless, burnout research projects have been developed in recent years.
Objectives
To examine the predictive capacity that empathy has on burnout syndrome in health professionals.
Methods
A non-experimental, cross-sectional design was proposed. The type of study was correlational-descriptive since it was sought out to explore a functional relation through the prognosis of a criterion variable. Sample: 200 (100 female and 100 male).
Results
First, the variance of cognitive and Affective Empathy was dug out in the emotional exhaustation criterion scale. Results accounted for 15% of variability in emotional exhaustation. (Corrected R 2 = .15, F = 17,56, p = 0,00). The best predictor of emotional exhaustation refers to Cognitive Empathy. (B = -.27, p = 0.00). It does not seem that Affective Empathy acts as a predictor variable of Emotional Exhaustation. (Table 1).Table 1

The predictive capacity of Empathy in relation to Depersonalization was estimated (Corrected R 2 = .20, F = 25,4, p = 0.00). Cognitive and affective empathy were included as predictor variables and MBI as a criterion variable (Table 2). On one hand, the best predictor of Depersonalization is the Cognitive Empathy. On the other hand, regarding Affective Empathy, it does not act as a predictor of Depersonalization.Table 2

An increased risk of suicide has been reported by psychiatric patients, including schizophrenia1. Numerous evidence suggests alterations in the grade of pro-inflammatory impact on suicidal behavior2, and this relation has been shown in patients with mood or anxious disorders3,4. However, the grade of inflammation impact suicidal behavior in patients with schizophrenia has hardly been investigated.
Objectives
Identify peripheral blood biomarkers of suicidal behavior in patients with schizophrenia, including inflammatory and lipid profile parameters.
Methods
Secondary analysis of a cross-sectional study. Sample: 254 patients with schizophrenia, aged 18-72. Assessments: ad-hoc demographic and clinical questionnaire, PANSS, CDS, CAINS, PSP. Inflammatory and lipid parameters: C-reactive protein (PCR), interleukin 6 (IL-6); high-density lipoprotein cholesterol (HDL-C), low density lipoprotein cholesterol (LDL-C), total cholesterol (TC), triglyceridaemia (TG). Statistical analysis: Correlations, T Student, U Mann-Withney and lineal regression.
Results
Mean age: 40.49 (13.10). Men: 64.2%.
No statistically significant differences were found between patients with suicide attempts and those without in any of the inflammatory or lipid parameters (p>0.05). However, differences were found in terms of suicide attempts (yes/no) in the PANSS negative (T=-2.217; p=0.028) and PANSS general psychopathy (T=-4.224; p< 0.001), in depressive symptoms (T =-6.967; p< 0.001), and the MAP subscale of the CAINS (T= -3.741; p<0.001).
Among patients with suicide attempts (n=42; 16.52% of the sample) (mean=1.90; sd=1.73; Range:1-7), statistically significant correlations were found with PCR (r=0.309; p=0.046), but not with cytokines and lipid parameters. On the other hand, no correlations were found with age, sex, length of illness, and any of the clinical scales.
A multiple linear regression was performed considering the number of suicide attempts as the dependent variable and as independent variables, age, sex, and those that were significant in the bivariate analysis (PCR).
A predictive model was found that explains 9.60% of the variance of number of suicide attempts (F = 4.224; p < 0.001). The variable that entered the model was PCR (β= 0.309; p=0.046).
Conclusions
The increase in inflammation (manifested by the elevation of PCR) is related to an increase in the number of suicides. On the contrary, no correlations were found with lipid parameters or interleukins.
Children who have undergone an oncological process and have received treatment with chemotherapy or radiotherapy on the central nervous system may have significant neurocognitive sequelae. Some video games have shown neurocognitive benefits in people with impairments in different areas, such as attention or memory.
Objectives
This work aims to demonstrate the benefit of a video game-based training program to improve the neurocognitive profile in a child survivor of cancer.
Methods
The patient is a 9-year-old female who was diagnosed with acute lymphoblastic leukemia at the age of 4 years. She received routine treatment of this disease by chemotherapy, including high-dose chemotherapy (with blood-brain barrier crossing) and intrathecal chemotherapy. She is currently 3 years after the end of treatment.
The Continuous Performance Test 3 (CPT-3) (sustained attention/vigilance) was administered before and after a multifaceted training program consisting of playing 3 video games for 12 weeks, as follows: a brain-training game (4 days per week, 7-12 minutes per day), a skill-training game (2 days per week, 10 minutes per day) and an exergaming game (2 days per week, 10 minutes per day).
Results
Prior to intervention, the patient had 3 atypical z-scores on the CPT-3 (z scores: mean = 0, S.D. = 1), with a pattern compatible with ADHD (omissions z = 1.2; hit reaction time z = 3.4; hit reaction time block change z = 1.2). After intervention, she had only an atypical z-score (hit reaction time z = 3.6), with a pattern compatible with slowing, without ADHD.
Conclusions
The neuropsychological evaluation of this patient showed an improvement in his attentional pattern on the CPT-3 after the video game-based training.
Short-chain fatty acids (SCFA) are bacterial metabolites that, within microbiome-gut-brain axis, make a promising research line on etiopathology of mental diseases like schizophrenia (SZ) and major depression disorder. Besides, depressive symptoms are frequent clinical features of SZ.
Objectives
- Describe fecal SCFA concentrations in SZ patients.
Cross-sectional study of 67 outpatients [mean age=43.52±12.42, range=22-67; males=40 (59.7%)] with diagnosis (DSM-5) of SZ recruited from their mental health clinics in Oviedo (Spain).
- Chlorpromazine equivalent doses (CPZ-ED), use of antidepressants.
- MetS (ATP-III), body mass index (BMI; kg/cm2).
- Statistics: Spearman correlation, U Mann-Whitney, ANCOVA.
Results
14 patients showed clinical depression (CDS≥5). There were no differences in age or sex between groups. 36 patients (53.7%) showed systemic low-grade inflammation (CPR≥0.3mg/dL) and 32 (30.8%) MetS.Table 1 shows fecal SCFA levels by depressive state. Means (SD) are ahown.Table 1

It also showed a trend towards statistical relation for CPZ-ED with Propanoate (r=-0.253,p=0.039) and Total SCFA (r=-0.253,p=0.039). We found no correlation in SCFA with MetS, CGI, PANSS-N, BMI, IPAQ, MEDAS and other toxic habits.
ANCOVA was performed to Acetate and Total SCFA using depression state as independent variable and Age and CPZ-ED as covariates. There was a trend towards statistical significance for Acetate (F=3.937,p=0.052,η2=0.059) whereas Total SCFA showed no difference (F=1.350,p=2.250,η2=0.021).
Conclusions
There seems to be lower levels of fecal Acetate in SZ patients with depressive symptoms, considering age and antipsychotic intake. In our sample there was no relation between SFCA and clinical severity, lifestyle, comorbidities or antidepressant use.
Childhood cancer survivors have neurocognitive sequelae that in most survivor follow-up programs are underdiagnosed and for which there is usually no treatment plan.
Video games have demonstrated various psychological and neurocognitive benefits in different subpopulations, such as patients with organic neurological deficits or children with ADHD. However, few studies have been carried out using video games-based interventions in the paediatric oncology population.
Objectives
The aim of this work is to present the WINNERS study protocol, the objectives of which are to diagnose the neurological and cognitive sequelae in child cancer survivors, and to demonstrate the benefit in these areas of a training program based on video games.
Methods
A randomized controlled and unblinded trial is presented. Fifty-six patients aged 8 to 17 years stratified into two age groups (8-12 and 13-17) who had received any of the following treatments 1 to 6 years before the enrolment will be selected: high-dose chemotherapy with blood-brain barrier crossing, intrathecal or intraventricular chemotherapy, CNS radiotherapy or hematopoietic stem cell transplantation.
A neuropsychological evaluation will be performed consisting of a battery of neuropsychological tests to assess parameters such as attention, memory, visuospatial ability or speed of response, as well as a neuroimaging evaluation by structural and functional magnetic resonance imaging. The evaluation will be repeated 3 months and 6 months after the enrolment. Patients will be randomized to a treatment group or to a recycled waiting group. Intervention will consist on a 12-week training at home using 3 video games: a brain training game, an exergaming game and a skill training game.
Results
According to the hypotheses of this study, it is expected that the proposed program of videogame-based interventions will improve neurocognitive and other wellbeing parameters in the intervention group.
Conclusions
This study aims to improve the quality of care for patients who have survived a cancer disease by detecting sequelae that have so far been poorly attended, and by proposing a gamification-based intervention program that is effective and attractive for this population.
Cannabinoid hyperemesis syndrome (CHS) is an underrecognized condition characterized by acute episodes of intractable nausea and vomiting, colic abdominal pain and restlessness related to chronic cannabis use. Antiemetics commonly fail to alleviate the severe nausea and vomiting. A very particular finding is the symptomatic relief with hot water. Antipsychotics (such as haloperidol), benzodiazepines and/or capsaicin cream appear to be the most efficacious in the treatment of this unique disorder. Precisely, it has been studied that transient relief of symptoms with topic capsaicin or hot water share the same pathophysiology. Nevertheless, abstinence from cannabis remains the most effective way of mitigating morbidity associated with CHS.
Objectives
The objective is to study this phenomenom in our hospital and to alert of its existence in order to avoid a suspected misdiagnosis and overdiagnosis.
Methods
We report a case series of seven patients who attended the Emergency Room (ER) of a third level hospital located in Cantabria (Spain) where a psychiatric evaluation was demanded.
Results
The reasons for consultation were agitation and/or compulsive vomit provocation and showers. They were all women, with a median age of 29 years (range 21 to 38), who all smoked cannabis and in probable high doses (seven to up to twenty joints per day, information was missing in three of the patients) and probable long duration of consumption (more than nine years up to twenty-three, information was missing in three of the patients).
One of the most striking findings is the time to diagnosis, being the median of years of more than eight (range from two to twenty-one). In all of the cases there is a hyperfrequentation to the ER for this reason (not counting other emergency centres we have in Cantabria which we don´t have access to), being the average of almost twenty-two times (thirteen up to thirty times), not diagnosing it until last visits. Another interesting fact is that Psychiatric evaluation is done approximately in a third of the visits, being the department that makes all of the diagnosis except in one case. In all of the cases there are a lot of diagnostic orientation doubts from different medical departments, being the two most common psychiatric misdiagnosis: Other Specified Anxiety Disorder and Other Specified Feeding or Eating Disorder. Two of the patients were hospitalized in an acute psychiatric unit for this reason, one of them nine times and the other patient, twice.
Conclusions
CHS has a very particular presentation which makes its recognition very simple. From our experience, it is an unknown entity for most of the doctors, something that needs to change in order to make a correct therapeutic management. Larger studies need to be done to make this findings more solid and for further information.
Sodium oxybate, an effective treatment for narcolepsy-associated daytime sleepiness and cataplexy, has been extensively. Despite its therapeutic benefits, sodium oxybate is not without its risks, and adverse psychiatric effects have been documented. This case report highlights a rare manifestation of sodium oxybate-related secondary mania with psychotic symptoms in a patient with narcolepsy, emphasizing the importance of recognizing and managing such adverse events. Additionally, we provide a brief review of similar cases reported in the literature.
Objectives
This report aims to describe the presentation, evaluation, and management of sodium oxybate-induced secondary mania with psychotic symptoms in a patient with narcolepsy. We also discuss the potential mechanisms underlying this adverse reaction and its clinical implications. Furthermore, we summarize findings from previous studies that have reported cases of secondary mania associated with sodium oxybate use.
Methods
We present the case of Mr. X, a 48-year-old male diagnosed with “Narcolepsy with cataplexy,” who had been receiving sodium oxybate treatment for 11 years. He was admitted to the hospital following a mild head injury and the emergence of a manic episode with psychotic features. Comprehensive clinical evaluation, including medical history, toxicology screening, and neuroimaging, was conducted.
Results
Upon evaluation, Mr. X exhibited hyperactivity, restlessnes, grandiose delusions, paranoid delusions related to hospital staff, and decreased need for sleep. Notably, he had been consuming sodium oxybate excessively. Sodium oxybate was discontinued, and low-dose olanzapine was initiated. Within 24 hours, his manic and psychotic symptoms resolved. He admitted to overusing his medication, and his family reported a recent increase in his activity level. A review of the literature revealed similar cases of sodium oxybate-induced secondary mania with psychotic symptoms.
Conclusions
This case underscores the importance of vigilance for psychiatric side effects of sodium oxybate, particularly in patients with a history of substance abuse or potential overuse. Secondary mania associated with medications is a rare but significant clinical entity. Prompt recognition and intervention are crucial for patient safety and well-being. Further research is needed to elucidate the mechanisms underlying such reactions and to establish guidelines for their prevention and management.
Until 2020, only Belgium, Luxembourg, Switzerland, and the Netherlands legalized euthanasia and assisted suicide in Europe. Spain joined this list in March 2021 with the Euthanasia Regulation Law. However, the practice of euthanasia and assisted suicide in individuals with severe mental disorders is complex due to potential cognitive and decision-making challenges. Psychiatrists play a vital role in evaluating such requests.
Objectives
he case of a patient with recurrent depressive disorder requesting euthanasia is presented, followed by a theoretical review of the subject.
Methods
A case is presented with a bibliographic review.

An 89-year-old man with a history of one prior brief psychiatric hospitalization for depression three years ago was admitted after attempting suicide with an overdose of medication. He reports depressive symptoms of several years of evolution. Medical tests came back normal, but he had a urinary catheter due to voiding issues. He was initially on a medication regimen of amitriptyline, clomethiazole, and fluvoxamine. Despite his depressive state, he maintained his cognitive and decision-making abilities. Medication adjustments were made, including discontinuing amitriptyline and switching fluvoxamine to amitriptyline. His depressive symptoms worsened after three days, leading to the addition of trazodone to his treatment. He also developed urinary symptoms and was diagnosed with a urinary tract infection and metastatic prostate cancer during urological evaluation. Emotionally, he became more apathetic, anergic, and anhedonic, frequently expressing a desire for euthanasia, even with medication changes. Hyponatremia led to the discontinuation of duloxetine and the introduction of venlafaxine. To address anxiety and sleep problems, clomethiazole was replaced with mirtazapine. Upon learning of his cancer diagnosis, his mood deteriorated further, along with increased anxiety and continued mentions of euthanasia. Lorazepam was introduced, and he was informed of his right to request euthanasia after discussing therapeutic options with urology. Following this consultation, the patient became calmer, stopped expressing thoughts of death, and began making short-term plans, including the possibility of receiving palliative care at home upon discharge.
Conclusions
Euthanasia and assisted suicide in severe mental disorders are complex due to ethical and medical challenges. Patients must understand their condition, prognosis, and have decision-making capacity. Assessing their suffering is crucial. Coexisting mental and organic issues complicate the request’s origin. In SMD, determining irreversibility is tricky, as these are often chronic, non-terminal conditions. Exhausting treatment options is essential before considering euthanasia, despite patient treatment refusal. Limited research underscores the need for more studies.
Major depressive disorder (MDD) is defined as a mental disorder of multifactorial etiology, which presents with mood disturbance, mainly sadness associated with loss of interest or pleasure. Light therapy (LT) is a therapeutic intervention consisting of daily exposure to a light source. This study aims to evaluate the effects of LT on anxious-depressive symptomatology and sleep in a sample of patients diagnosed with depression.
Objectives
This study aims to evaluate the effects of LT on anxious-depressive symptomatology and sleep in a sample of patients diagnosed with depression.
Methods
Prospective case-control study, in which the cases are outpatients diagnosed with MDD and the controls are healthy individuals. Both groups underwent LT sessions and were assessed by means of validated scales, anxiety and depression symptoms before and after LT sessions, as well as changes in sleep patterns through a sleep measuring device.
Results
11 cases and 18 controls were included in the study. Of the participants, 62.1% were female and 37.9% were male. The mean age of the sample was 54.03 □ 11.55 years. There were significant case differences in the pre and post LT scores of the depression scale. There were no significant differences in the changes in superficial, deep and total sleep and in the anxiety scale scores.
Conclusions
In the sample analysed, LT has significant effects on the cases at the level of the depression scale.
The glucagon-like peptide-1 (GLP-1) receptor agonist Semaglutide has been widely used to manage type 2 diabetes due to its favourable effects on glycemic control and weight reduction. Proved to be safe in adults and elderly patients with renal or hepatic disorders demanding no dose modification. Affective symptoms are not listed as side effects in the product information. However, there is a recent investigation going on by the European Medicines Agency (EMA) after three flagged cases of suicidal thoughts in Iceland. In contrast, the Food and Drug Administration (FDA) recommend that patients with this treatment are monitored for suicidal thoughts or behaviour.
Objectives
This case study explores the possible relationship between Semaglutide treatment and the onset of a manic episode in a 57-year-old male with no history of psychiatric disorders.
Methods
We present a 57-year-old male with no psychiatric history of interests, with a previous good functioning. A one-week history of disruptive behaviours started, characterized by excessive cheerfulness, heightened euphoria, and reduced need for sleep. Family members describe a complex situation at home, with frequent outings by the patient, engaging in conversations with strangers, getting lost, and becoming more irritable with them. The patient and family relate this mood change after initiating Semaglutide for diabetes control, starting at 7mg doses. The temporal relationship between the initiation of Semaglutide therapy, precisely a dose escalation to 7mg, and the onset of manic symptoms prompted family members to notify the patient’s endocrinologist. Due to the inability to manage the patient at home and his unpredictability, they sought help at the emergency department, resulting in a psychiatric admission. Imaging and analytical tests show no significant abnormalities.
Results
During his stay in the psychiatry department, semaglutide dosage was reduced, and treatment with Aripiprazole was initiated at doses of 5mg, given the metabolic profile associated with medical comorbidities (obesity, chronic renal failure and diabetes). Subsequent clinical observations showed a gradual resolution of manic symptoms and an improvement in the patient’s overall mental state.
Conclusions
This case highlights the importance of monitoring and recognizing potential neuropsychiatric side effects associated with Semaglutide therapy, particularly in individuals without a prior psychiatric history. Further research is warranted to elucidate the underlying mechanisms linking Semaglutide with mood disturbances and to identify risk factors that may predispose certain patients to develop manic states in response to this GLP-1RA. Clinicians should remain vigilant and consider alternative treatment options if such side effects occur, ensuring comprehensive management of patients receiving Semaglutide for diabetes control.
