The digitalization of the humanitarian sector promises to enable swifter and more efficient aid delivery. However, as humanitarian organizations (HOs) increasingly rely on digital technologies, they become more vulnerable to cyber threats. This vulnerability was highlighted by the data breach suffered by the International Committee of the Red Cross in 2022, and the cyberattacks during the conflicts in Ukraine and the Gaza Strip. Unfortunately, despite HOs recognizing the importance of implementing strategies to mitigate the impact of potential cyber incidents, these often face both academic and practical limitations, as they are primarily designed for private companies.

This study aims to identify cyber threats, challenges and gaps in current strategies reported by the literature to provide recommendations for strengthening cybersecurity strategies tailored to the unique needs and characteristics of HOs.

This study presents the results of a comprehensive review that maps existing threats and challenges associated with the digitalization of humanitarian aid delivery, as well as the current cyber preparedness, response and communication strategies employed by HOs.

Our results reveal a range of cyber threats and challenges faced by HOs and show a notable lack of preparedness, response, and communication strategies to address these threats.

The absence of comprehensive strategies underscores the need for further research and the development of tailored solutions to strengthen cybersecurity within the humanitarian sector. HOs must draw lessons from other sectors and implement robust preparedness and response strategies to mitigate the impact of potential cyber incidents, ensuring the protection of victims and the organizations’ reputations.

Inadequate recruitment and retention impede clinical trial goals. Emerging decentralized clinical trials (DCTs) leveraging digital health technologies (DHTs) for remote recruitment and data collection aim to address barriers to participation in traditional trials. The ACTIV-6 trial is a DCT using DHTs, but participants’ experiences of such trials remain largely unknown. This study explored participants’ perspectives of the ACTIV-6 DCT that tested outpatient COVID-19 therapeutics.

Participants in the ACTIV-6 study were recruited via email to share their day-to-day trial experiences during 1-hour virtual focus groups. Two human factors researchers guided group discussions through a semi-structured script that probed expectations and perceptions of study activities. Qualitative data analysis was conducted using a grounded theory approach with open coding to identify key themes.

Twenty-eight ACTIV-6 study participants aged 30+ years completed a virtual focus group including 1–4 participants each. Analysis yielded three major themes: perceptions of the DCT experience, study activity engagement, and trust. Participants perceived the use of remote DCT procedures supported by DHTs as an acceptable and efficient method of organizing and tracking study activities, communicating with study personnel, and managing study medications at home. Use of social media was effective in supporting geographically dispersed participant recruitment but also raised issues with trust and study legitimacy.

While participants in this qualitative study viewed the DCT-with-DHT approach as reasonably efficient and engaging, they also identified challenges to address. Understanding facilitators and barriers to DCT participation and DHT interaction can help improve future research design.

This systematic review and meta-analysis evaluates the prevalence of disruptive mood dysregulation disorders (DMDD) in community-based and clinical populations.

PubMed and PsychINFO databases were searched, using terms specific to DMDD, for studies of prevalence and comorbidity rates conducted in youths below 18.

Fourteen studies reporting data from 2013 to 2023 were included. The prevalence of DMDD in the community-based samples was 3.3% (95% confidence interval [CI], 1.4–6.0) and 21.9% (95% CI, 15.5–29.0) in the clinical population. The differences in the identification strategy of DMDD were associated with significant heterogeneity between studies in the community-based samples, with a prevalence of 0.82% (95% CI, 0.11–2.13) when all diagnosis criteria were considered. Anxiety, depressive disorders, and ADHD were the most frequent comorbidity present with DMDD. The association with other neurodevelopmental disorders remained poorly investigated.

Caution is required when interpreting these findings, considering the quality of the reviewed data and the level of unexplained heterogeneity among studies. This review stresses the importance of considering a strict adhesion to DMDD criteria when exploring its clinical correlates.

This study aimed to assess the association between emotional attitudes towards diabetes, eating behaviour styles and glycaemic control in outpatients with type 2 diabetes.

Observational study.

Endocrinology Division of Hospital de Clínicas de Porto Alegre, Brazil.

Ninety-one outpatients diagnosed with type 2 diabetes. Baseline assessments included data on clinical parameters, lifestyle factors, laboratory results, eating behaviour styles and emotional attitudes. All patients received nutritional counseling following diabetes recommendations. A follow-up visit was scheduled approximately 90 days later to evaluate changes in weight, medication dosages and glycated Hb (HbA1c) values. Patients were categorised based on their emotional attitude scores towards diabetes (positive or negative), and their characteristics were compared using appropriate statistical tests.

At baseline, no differences were observed in the proportion of patients with good glycaemic control, eating behaviour styles and emotional attitudes. However, patients with a positive attitude towards the disease exhibited a significantly better response in glycaemic control compared with the reference group (OR = 3·47; 95 % CI = 1·12, 10·75), after adjusting for diabetes duration, sex and medication effect score. However, when BMI was included in the model, the association did not reach statistical significance. Therefore, these results should be interpreted with caution.

Patients with a positive attitude towards diabetes showed a greater reduction in HbA1c levels following nutritional counseling. However, baseline BMI could be a potential confounding factor.

Obssesive Compulsive Disorder (OCD) is characterized by impaired neuropsychological functions that are also influenced by clinical variables and aging.

According to the literature, several of these neuropsychological deficits could be potential endophenotype markers.

The present study aimed to study what kind of cognitive deficits OCD patients have and how aging and clinical course modify their cognitive profiles campared with general population.

This study examined a sample of 60 adult outpatients with OCD diagnosis, who were matched with 70 healthy controls (HC). Cognitive performance in both groups was assessed using a neuropsychological battery including Rey-Osterrieth complex Figure (ROCF) and Digit Span Test (DGS). Based on previous research on neuropsychology of OCD, it was specified that these neuropsychological measures could be divided in two composites. The first composite, Executive function, includes Total Digit Span and the domain of organization of ROCF. The second composite, Non-Verbal Memory, includes the copy of ROCF, immediate recall, delayed recall and recognition of ROCF.

Severity of OCD symptoms was assessed by YBOCS and HDRS was used for symptoms of depression.

Both cognitive performance and clinical data were documented before and after a follow-up of 11 years.

During analysis, group differences between patients with OCD and HC regarding demographic and clinical characteristics at baseline and follow-up were calculated with independent t-tests and Pearson tests.

The main analysis tested if the change in cognitive function over time differed between patients and controls. To this end, a linear mixed model was used, examining the interaction between age, gender and time in both groups.

Older age, in patients with OCD and HC, was associated with poorer performance on executive function and nonverbal memory. Executive function was influenced by severity of OCD, and non-verbal memory by depressive symptoms at baseline. While, after the follow-up, as obsessive and affective symptoms improve along de follow-up, there is no significant change in the neuropsychological pattern.

At baseline, patients with OCD showed a poorer performance than HC in areas of nonverbal memory and executive function. After de follow-up, there is a poorer performance in the cognitive function in both groups, as they get older. However, there is no significant difference in this change between patients and HC.

Results suggest that OCD is characterized by the existence of dysfunction in several neuropsychological areas that are influenced by time and clinical variables.

Nevertheless, this alteration is no solely attributable to these factors, as they remain stable through time compared to the general population. Therefore, certain neuropsychological functions might be endophenotype traits of the disorder.

The assessment of MBI involves two important issues: 1) to know the underlying structure of the Mild Behavioral Impairment Checklist (MBI-C) a questionnaire designed to evaluates Neuropsychiatric Symptoms (NPS) in pre-dementia states; and 2) to consider self and proxy (i.e., study partner) symptom ratings that may not capture comparable samples. Our objective is to give some answer to these questions: first, to analyze the underlying structure of the MBI-C at baseline and follow-up using Multidimensional Scaling (MDS) and two, to determine how self and proxy ratings and the choice of rating type impact in the results of the MBI-C.

To analyze MBI-C structure, 200 Subjective Cognitive Decline and Mild Cognitive Impairment patients from the CompAS longitudinal study completed baseline and follow-up assessments. Two-step bidimensional weighted dichotomous MDS were performed. All items were included in the first step. Items closely associated with each dimension (1 SD above or below the mean) were selected in a second step to obtain the final models solution.

We will also present a review of the literature on the importance of self and proxy MBI-C ratings. We will also present new empirical evidence based on data from over 10,000 cognitively normal.

Results from baseline and follow-up showed two dimensions: Dimension I (right-left) differentiate high and low emotional activation and Dimension II (top-down) high and low behavioral activation. The combination of both generates 4 quadrants: resistance, restlessness, flattening and desolation. The final models were built considering the most relevant items, with little differences between baseline and follow-up. The good fit of the models, type of two-dimensional solution and group weights were similar in baseline and follow-up.

Regarding our second objective, the results suggest that self and proxy ratings may not capture comparable samples and that the choice of rating type can indeed impact the conclusions drawn from analysis.

The 4 quadrants identified could be the most useful NPS to determine risk factors for predementia patients. Also, the findings suggest that the way of applying the MBI-C has relevant implications.

The purpose of the research project is to analyze the long-term evolution of obsessive-compulsive disorder (OCD) from of a study of a cohort of patients prospectively followed over a period ranging from 5 to 20 years, treated for according to therapeutic guidelines mediating serotonin reuptake inhibitors (IRS) and drug enhancers (antipsychotics) and cognitive behavioral therapy and evaluated in a standardized manner.

To assess the long-term course of Obsessive-Compulsive Disorder (OCD) in a cohort of patients treated according to current clinical guidelines; to analyse possible prognostic factors associated with the long-term course of the disorder including clinical and sociodemographic variables, as well as genetic and neuroimaging biomarkers, and their interaction, and finally to study neuroanatomical and functional cerebral connectivity changes after 15 years of treatment in a subsample of patients.

Prospective, descriptive, and observational study of a cohort of OCD patients, receiving treatment at the Department of Psychiatry of Hospital de Bellvitge since 1998, according to a standardized protocol. Follow-up period ranges from 5 (n=423), to 10 (n= 247) and 15 years (123). Baseline clinical and sociodemographic assessment, long-term evolution and information on treatments provided are available for the whole sample. Data on whole exome sequencing is available for 300 of the patients included in the cohort and baseline structural neuroimaging and cerebral functional connectivity has been analysed in 168 subjects. To expand the analysis of genetic biomarkers, we propose the study of de novo variants through exome analysis of 50 trios (patient and both parents) selected among those subjects that have reached 15 years of follow-up (25 trios with patients within the “long-term remission” group and 25 trios with patients with chronic OCD). De novo variants detected in the trio analysis will be replicated in the rest of the sample. A structural and resting state MRI will be obtained in a subsample of 100 patients recruited among those who have completed a minimum follow-up period of 15 years, to assess cerebral changes associated with the long-term course of the disorder.

in the current moment the recruitment period of the study has ended and all the data is being statistically analysed in order to provide solid results in a short period of time.

The identification of those factors associated with an increased risk of chronic disease is an element essential to offer personalized treatment to our patients and improve their prognosis, emphasizing the intensive use of those therapeutic strategies for which we can predict a better response and modifying to the extent of, if possible, environmental factors or factors of access to treatment that contribute to perpetuate obsessive symptoms.

Obsessive–Compulsive Disorder (OCD) is a disabling and chronic illness defined by the presence of obsessions and/or compulsions. Recently it has been proposed that the perinatal period may act as a trigger in this disorder, leading to its onset or exacerbation.

Variations in pregnancy-related hormones are believed to be one of the main etiological theories for the development of perinatal OCD (pOCD). Perhaps for that reason research has been almost exclusively focused on the development of this disorder in mothers. We aim to investigate pOCD in fathers.

A non-systematic review was conducted via electronic searches of PubMed. The keywords used were “Perinatal”, “Father”, “OCD”, “Obsessive-compulsive disorder”.

Unwanted intrusive thoughts are experienced with a similar prevalence in mothers and fathers. The same seems to be true regarding compulsions. However, it does appear that mothers are more distressed by these symptoms, which tend to be baby-related, usually concerning themes of suffocation, accidents or contamination. It is hypothesized that this seemingly different impact is related to the fact that mothers are more often the primary caregivers than fathers, thus feeling more distress because they are imbued with a greater responsibility. Accordingly, pOCD symptoms tend to be more severe in fathers who consider their baby-related obsessions meaningful, often confusing them as a desire to carry out such thoughts. These findings are consistent with the Cognitive-Behavioral Theory of OCD, highlighting that purely biological theories for the development of pOCD might not suffice.

Research indicates a similar presence of OCD symptoms in postnatal mothers and fathers, although it seems that mothers may experience more distress. Underlying dysfunctional beliefs seem to be responsible for the negative appraisal of these symptoms, predicting the development of the disorder in question. Further research of pOCD should seek to better characterize the onset or exacerbation of this disorder in fathers.

Cocaine is a highly addictive psychostimulant that affects synaptic activity with structural and functional adaptations of neurons. The transmembrane synaptic vesicle glycoprotein 2A (SV2A) of pre-synaptic vesicles is commonly used to measure synaptic density, as a novel approach to the detection of synaptic changes. We do not know if a single dose of cocaine suffices to affect pre-synaptic SV2A density, especially during adolescence when synapses undergo intense maturation. Here, we explored potential changes of pre-synaptic SV2A density in target brain areas associated with the cocaine-induced boost of dopaminergic neurotransmission, specifically testing if the effects would last after the return of dopamine levels to baseline.

We administered cocaine (20 mg/kg i.p.) or saline to rats in early adolescence, tested their activity levels and removed the brains 1 hour and 7 days after injection. To evaluate immediate and lasting effects, we did autoradiography with [3H]UCB-J, a specific tracer for SV2A, in medial prefrontal cortex, striatum, nucleus accumbens, amygdala, and dorsal and ventral areas of hippocampus. We also measured the striatal binding of [3H]GBR-12935 to test cocaine’s occupancy of the dopamine transporter at both times of study.

We found a significant increase of [3H]UCB-J binding in the dorsal and ventral sections of hippocampus 7 days after the cocaine administration compared to saline-injected rats, but no differences 1 hour after the injection. The [3H]GBR-12935 binding remained unchanged at both times.

Cocaine provoked lasting changes of hippocampal synaptic SV2A density after a single exposure during adolescence

The aim of this study was to investigate the psychometric properties of the Spanish version of the Stigma of Occupational Stress Scale for Doctors (SOSS-D) and the factors associated with Physician Burnout in Paraguay.

Participants included 747 Paraguayan healthcare workers, aged 24–77 years old, of both sexes. SOSS-D was translated into Spanish and validated through an exploratory and confirmatory factor analysis. Participants were also scored with the Oldenburg Burnout Inventory (OLBI), the CAGE questionnaire, and the stigma subscale of the Perceived Barriers to Psychological Treatment (PBPT) measure.

Three factors had a raw eigenvalue greater than 1, and explained 61.7% of total variance. The confirmatory analysis confirmed that the scale is three-dimensional. The model adjustment was good, according to all fit indices. OLBI results indicate clinically significant disengagement in 85.9% and clinically significant exhaustion in 91.6% of participants. Of the 747 participants, 57.6% reported alcoholic beverage consumption and among those, 19.3% had problematic alcohol consumption according to the CAGE questionnaire. The correlation between SOSS-D and the stigma subscale of the PBPT was statistically significant (r = 0.245, p < 0.001).

The Spanish version of the SOSS-D was found to have good psychometric properties and adequately reproduces the three-dimensional model of the original English version.
