Introduction

Epilepsy is a common neurological disorder characterised by recurrent seizures. Almost half of patients who have an unprovoked first seizure (UFS) have additional seizures and develop epilepsy. No current predictive models exist to determine who has a higher risk of recurrence to guide treatment. Emerging evidence suggests alterations in cognition, mood and brain connectivity exist in the population with UFS. Baseline evaluations of these factors following a UFS will enable the development of the first multimodal biomarker-based predictive model of seizure recurrence in adults with UFS.

Methods and analysis

200 patients and 75 matched healthy controls (aged 18–65) from the Kingston and Halifax First Seizure Clinics will undergo neuropsychological assessments, structural and functional MRI, and electroencephalography. Seizure recurrence will be assessed prospectively. Regular follow-ups will occur at 3, 6, 9 and 12 months to monitor recurrence. Comparisons will be made between patients with UFS and healthy control groups, as well as between patients with and without seizure recurrence at follow-up. A multimodal machine-learning model will be trained to predict seizure recurrence at 12 months.

Ethics and dissemination

This study was approved by the Health Sciences and Affiliated Teaching Hospitals Research Ethics Board at Queen’s University (DMED-2681-22) and the Nova Scotia Research Ethics Board (1028519). It is supported by the Canadian Institutes of Health Research (PJT-183906). Findings will be presented at national and international conferences, published in peer-reviewed journals and presented to the public via patient support organisation newsletters and talks.

Association between dementia risk and ulcerative colitis, with and without colectomy: a Swedish population-based register study

Por: Garcia-Argibay · M. · Hiyoshi · A. · Montgomery · S.
Objective

This study aims to investigate the association of ulcerative colitis (UC) with all-cause dementia and assess differences in those with and without a total colectomy.

Design, setting and participants

This Swedish prospective register-based study comprised 4.8 million individuals aged at least 59 years between 1964 and 2018 with the linkage of several Swedish national registers.

Primary and secondary outcome measures

Individuals with dementia were defined according to International Classification of Diseases diagnostic codes and Anatomical Therapeutic Classification codes for medication prescriptions. Fitting Cox hazards models, the risk of developing all-cause dementia in individuals with and without UC was estimated. Further, we compared the risk of all-cause dementia among those with and without a colectomy.

Results

Among 4 821 488 individuals (52.6% females) followed for 84.1 million person-years between 1964 and 2018, the incidence rate of all-cause dementia was 63.90 (63.73–64.07) events per 10 000 person-years in individuals without UC, 94.80 (92.04–97.64) among those with UC, 95.01 (92.25–97.86) in those with UC but without colectomy and 63.42 (40.92–98.31) in those with UC and a colectomy. Adjusted Cox models showed an increased all-cause dementia risk in individuals with UC (HR 1.07, 95% CI 1.04 to 1.10). We found no differences between unexposed individuals and those with UC and a colectomy (HR 0.89, 95% CI 0.57 to 1.38).

Conclusion

The findings are consistent with previous evidence suggesting a slightly increased dementia risk among individuals with UC. This study provided no evidence of further risk increase of dementia among those who had a colectomy.

Dimensions of suffering and the need for palliative care: experiences and expectations of patients living with cancer and diabetes and their caregivers in Mexico - a qualitative study

Por: Doubova · S. V. · Bhadelia · A. · Perez-Moran · D. · Martinez-Vega · I. P. · Garcia-Cervantes · N. · Knaul · F.
Objectives

Over 40 million people in low-income and middle-income countries (LMICs) experience serious health-related suffering (SHS) annually and require palliative care. Patient and caregiver experiences of SHS in LMICs are understudied despite their importance in guiding palliative care provision. Diabetes and cancer are the second-leading and third-leading causes of death in Mexico, causing a significant SHS burden on patients, families and health systems. This study examines SHS and palliative care from the point of view of patients with cancer and diabetes and their caregivers.

Design

A qualitative descriptive study based on in-depth telephone interviews was conducted between August 2021 and February 2022. Data were analysed through inductive thematic analysis.

Participants

Overall, 20 patients with end-stage cancer, 13 patients with diabetes and 35 family caregivers were interviewed individually.

Setting

Participants were recruited from two family medicine clinics and a pain clinic in Mexico City.

Results

Seven themes emerged: (1) suffering as a multifaceted phenomenon, (2) diversity in perceptions of suffering, (3) different coping strategies, (4) need and perceived importance of relief from suffering, (5) barriers to accessing services to relieve suffering, (6) demand for the health sector’s active and humane role in addressing suffering and (7) preferences and need for comprehensive care for relief from suffering. The primary coping strategies included family companionship, protective buffering and faith-based support. Participants lacked knowledge of palliative care. They expressed the importance of relief from suffering, viewing it as the health sector’s responsibility and requesting more humane, personalised care and access to medicines and pain clinics.

Conclusions

The multifaceted nature of SHS highlights the health system’s responsibility to provide high-quality palliative care. Policies to enhance access to palliative care should integrate it into primary care, redesigning services towards patient and caregiver biopsychosocial and spiritual needs and ensuring access to medicines and competent health personnel.

Effectiveness, safety and costs of the FreeStyle Libre glucose monitoring system for children and adolescents with type 1 diabetes in Spain: a prospective, uncontrolled, pre-post study

Objectives

This study aimed to evaluate the effectiveness, safety and costs of FreeStyle Libre (FSL) glucose monitoring system for children and adolescents with type 1 diabetes mellitus (T1DM) in Spain.

Design

Prospective, multicentre pre-post study.

Setting

Thirteen Spanish public hospitals recruited patients from January 2019 to March 2020, with a 12-month follow-up.

Participants

156 patients were included.

Primary and secondary outcome measures

Primary: glycated haemoglobin (HbA1c) change. Secondary: severe hypoglycaemic events (self-reported and clinical records), quality of life, diabetes treatment knowledge, treatment satisfaction, adverse events, adherence, sensor usage time and scans. Healthcare resource utilisation was assessed for cost analysis from the National Health System perspective, incorporating direct healthcare costs. Data analysis used mixed regression models with repeated measures. The intervention’s total cost was estimated by multiplying health resource usage with unit costs.

Results

In the whole sample, HbA1c increased significantly (0.32%; 95% CI 0.10% to 0.55%). In the subgroup with baseline HbA1c≥7.5% (n=88), there was a significant reduction at 3 months (–0.46%; 95% CI –0.69% to –0.23%), 6 months (–0.49%; 95% CI –0.73% to –0.25%) and 12 months (–0.43%; 95% CI –0.68% to –0.19%). Well-controlled patients had a significant 12-month worsening (0.32%; 95% CI 0.18% to 0.47%). Self-reported severe hypoglycaemia significantly decreased compared with the previous year for the whole sample (–0.37; 95% CI –0.62 to –0.11). Quality of life and diabetes treatment knowledge showed no significant differences, but satisfaction increased. Adolescents had lower sensor usage time and scans than children. Reduction in HbA1c was significantly associated with device adherence. No serious adverse effects were observed. Data suggest that use of FSL could reduce healthcare resource use (strips and lancets) and costs related to productivity loss.

Conclusions

The use of FSL in young patients with T1DM was associated with a significant reduction in severe hypoglycaemia, and improved HbA1c levels were seen in patients with poor baseline control. Findings suggest cost savings and productivity gains for caregivers. Causal evidence is limited due to the study design. Further research is needed to confirm results and assess risks, especially for patients with lower baseline HbA1c.

Influence of physical fitness components on personality factors and risk perception of children and adolescents: a cross-sectional study

Objectives

To examine the associations of cardiorespiratory fitness (VO2 max) and muscular strength with indicators related to the risk scale, such as perceived competence, sensation seeking, competitiveness, risk taking and risk perception in sports.

Design

Cross-sectional study.

Setting

High schools from the Region of Murcia (Spain).

Participants

Three-hundred-and-seventeen adolescents participated (mean age: 13.69±1.2 years old).

Primary and secondary outcome measures

Body mass, body height, Course-Navette test, upper limb strength and psychoeducational factors that determine the propensity towards sports accidents in school children, the Sports Accident Propensity Scale were evaluated. It was performance t-test for independent samples, stepwise multiple linear regression models and a multiple mediation analysis.

Results

The analysis showed significant differences with respect to sex in height, VO2 max, handgrip strength and in all factors of the questionnaire (p=0.02-2 max, strength in the handgrip test and age showed a higher score in factors 1 and 3. Higher scores in factor 2 were associated with better VO2 max and strength in handgrip test. Youngers and better values of strength in the handgrip showed higher score in factors 4 and 5. The mediation analysis with two mediating variables (handgrip strength and VO2 max) showed a significant indirect effect. When handgrip strength and VO2 max were included in the equations, the association between sex and each factor ceased to be significant.

Conclusion

This study highlights the potential benefits of muscular strength (handgrip) and VO2 max in the perceived risk scale, and the variable of age on this.

Assessment of psychological terror and its impact on mental health and quality of life in medical residents at a reference medical center in Mexico: A cross-sectional study

by Víctor Manuel Enriquez Estrada, Neftali Eduardo Antonio-Villa, Omar Yaxhemen Bello-Chavolla, Carlos Fredy Cuevas-García, Pedro Luis Vargas Gutiérrez, Irma Sau-Yen Corlay Noriega, Luis Rey García-Cortés

Background

Mobbing, particularly in medical residencies, can lead to psychological terror with lasting mental and physical health consequences. Its impact on Mexican residents, however, remains underexplored.

Aim

This study aimed to investigate the prevalence and associated factors of psychological terror among medical residents at a medical center in Mexico City.

Methods

In a cross-sectional study, medical residents from various specialties were assessed for mobbing domains, quality of life, and anxiety/depression using the Leymann Inventory of Psychological Terror (LIPT), 36-Item Short Form Health Survey, Beck Depression Inventory-II, and Beck Anxiety Inventory, respectively. Psychological terror was defined as a LIPT score ≥ p80. Linear and binomial logistic regression models were used to explore independent predictors of mobbing and psychological terror.

Results

Of the 349 participants included (median age: 28; IQR: 27–30 years), 19.5% (95% CI: 15.5%-24.0%) were identified with psychological terror. Furthermore, 39% reported higher-degree trainees as mobbing perpetrators. Women in surgical residencies in their second or fifth year were found to experience higher levels of mobbing. Manifested bullying, workplace stigma, and inappropriate tasks were the most impacted mobbing domains. Anxiety, diminished mental health quality of life, and higher degree of medical specialization were independent predictors of mobbing. Meanwhile, increased anxiety, affiliation to surgical specialties, and being in the second or fifth year of training were identified as predictors of psychological terror.

Conclusions

Mobbing and psychological terror are prevalent conditions among medical residents in Mexico. Identification of occupational conditions and adverse psychological stressors can help to improve quality of life and training of medical residents.

Assessment of oligomerization of bacterial micro-compartment shell components with the tripartite GFP reporter technology

by Lucie Barthe, Vanessa Soldan, Luis F. Garcia-Alles

Bacterial micro-compartments (BMC) are complex macromolecular assemblies that participate in varied metabolic processes in about 20% of bacterial species. Most of these organisms carry BMC genetic information organized in operons that often include several paralog genes coding for components of the compartment shell. BMC shell constituents can be classified depending on their oligomerization state as hexamers (BMC-H), pentamers (BMC-P) or trimers (BMC-T). Formation of hetero-oligomers combining different protein homologs is theoretically feasible, something that could ultimately modify BMC shell rigidity or permeability, for instance. Despite that, it remains largely unknown whether hetero-oligomerization is a widespread phenomenon. Here, we demonstrated that the tripartite GFP (tGFP) reporter technology is an appropriate tool that might be exploited for such purposes. Thus, after optimizing parameters such as the size of linkers connecting investigated proteins to GFP10 or GFP11 peptides, the type and strength of promoters, or the impact of placing coding cassettes in the same or different plasmids, homo-oligomerization processes could be successfully monitored for any of the three BMC shell classes. Moreover, the screen perfectly reproduced published data on hetero-association between couples of CcmK homologues from Syn. sp. PCC6803, which were obtained following a different approach. This study paves the way for mid/high throughput screens to characterize the extent of hetero-oligomerization occurrence in BMC-possessing bacteria, and most especially in organisms endowed with several BMC types and carrying numerous shell paralogs. On the other hand, our study also unveiled technology limitations deriving from the low solubility of one of the components of this modified split-GFP approach, the GFP1-9.

Leche materna versus sacarosa ante punción venosa y heel prick

Introducción: Las intervenciones que realizamos a los RN ingresados en nuestra unidad pueden causar dolor y estrés, traduciéndose en signos conductuales y fisiológicos. Método: Se realizó un ensayo clínico controlado aleatorizado en la UCI de neonatos durante un año, el objetivo fue conocer si existen diferencias significativas en cuanto al uso de leche materna vs sacarosa 25% como método analgésico no farmacológico en la realización de procedimientos dolorosos (punción venosa y punción del talón). Se usó para evaluar el dolor la escala de Susan Given Bells (antes y tras 2minutos de nuestra intervención). Material: Se incluyeron los recién nacidos entre 25-40 se-manas de gestación y que no cumpliesen criterios de exclusión. Resultados: Se usó para el análisis estadístico la t-student y el test de chi cuadrado, observando como principal resultado que en la extracción venosa (N=59) es más efectivo el uso de leche materna, sufriendo menor aumento del dolor tras la misma(p<0,029). También se observa relación significativa entre la edad gestacional corregida y el dolor tras la extracción venosa, obteniendo que los recién nacidos > 32 semanas tienen mayor aumento de dolor posterior (p<0,011). En la de punción de talón (N=76), no se hallaron diferencias entre la sacarosa y leche materna, tampoco al analizar otras variables (sexo, edad gestacional, crecimiento intrauterino retardado, llanto o canguro) Conclusiones: Se propone el uso de leche materna como método anal-gésico para el control del dolor en punción de talón y extracción venosa. Ya que demuestra su eficacia y carece de efectos secundarios.
