RESUMEN
Over the past decade, research using virtual reality and serious game-based instruments for assessing spatial navigation and spatial memory in at-risk and AD populations has risen. We systematically reviewed the literature since 2012 to identify and evaluate the methodological quality and risk of bias in the analyses of the psychometric properties of VRSG-based instruments. The search was conducted primarily in July-December 2022 and updated in November 2023 in eight major databases. The quality of instrument development and study design were analyzed in all studies. Measurement properties were defined and analyzed according to COSMIN guidelines. A total of 1078 unique records were screened, and following selection criteria, thirty-seven studies were analyzed. From these studies, 30 instruments were identified. Construct and criterion validity were the most reported measurement properties, while structural validity and internal consistency evidence were the least reported. Nineteen studies were deemed very good in construct validity, whereas 11 studies reporting diagnostic accuracy were deemed very good in quality. Limitations regarding theoretical framework and research design requirements were found in most of the studies. VRSG-based instruments are valuable additions to the current diagnostic toolkit for AD. Further research is required to establish the psychometric performance and clinical utility of VRSG-based instruments, particularly the instrument development, content validity, and diagnostic accuracy for preclinical AD screening scenarios. This review provides a straightforward synthesis of the state of the art of VRSG-based instruments and suggests future directions for research.
RESUMEN
OBJECTIVES: Investigate the factors influencing life space utilization in older Afro-descendant adults residing in Tumaco, Colombia - a marginalized region of the country. DESIGN: This cross-sectional study included 388 Afro-descendant older adults. The study assessed living space using the Life Space Assessment (LSA) scale and collected demographic data. Cognitive levels were measured with the Mini-Mental State Examination (MMSE), and depressive symptoms were assessed using the Yesavage scale. Socio-emotional indicators were determined with the Medical Outcomes Study (MOS). The research employed linear and logistic regression models for data analysis. RESULTS: On average, participants scored 27.0 on the LSA scale. A lack of perceived income resulted in a 10.44-point decrease on the LSA scale. For each unit increase in the MOS-Instrumental Dimension score, the LSA score increased by 0.52 points (95% CI 0.17-0.87). As for cognitive performance (MMSE scale), each one-point increase resulted in a 0.69 decrease in the LSA score (95% CI -1.25 to -0.12). CONCLUSION: Socioeconomic disadvantages limit living space utilization, particularly in the Afro-descendant population. Yet, social support can enhance living space use despite environmental and economic constraints.

BACKGROUND: Acute decompensated heart failure (ADHF) is one of the most frequent causes of emergency department (ED) visits. Point-of-Care Ultrasound (POCUS) is a reliable, easy-to-use, and available tool for an accurate diagnosis of ADHF. We aimed to analyze the impact of introducing POCUS as an additional tool to clinical standard diagnosis in clinical times of hospitalized heart failure patients. METHODS: Retrospective cohort study comparing patients consulting to ED for heart failure acute decompensation previous to the rutinary use of POCUS versus patients who received an ultrasound-guided diagnosis at entrance. Ultrasound evaluation was additional to standard diagnosis (which included natriuretic peptides, images, etc). Cumulative incidence functions were calculated for time to treatment, time to disposition decision, and time to discharge. We used a flexible parametric model for estimate the time ratio (TR) in order to reflect the effect of POCUS. RESULTS: A total of 149 patients were included. The most frequent comorbid condition was hypertension (71.8%) followed by type 2 diabetes (36.2%). B type natriuretic peptide (BNP) was over 500 ng/ml. Most patients had Stevenson B profile (83.9%) at admission. In the cumulative incidence model (Fig. A), the TR (time ratio) for the outcome time to treatment was 1.539 (CI 95% 0.88 to 2.69). The TR for the outcome time to disposition decision was 0.665 (CI 95% 0.48 to 0.99). The TR for the outcome time to discharge (hospital length of stay) was 0.663 (CI 95% 0.49 to 0.90). CONCLUSION: In our study, the introduction of POCUS to ADHF patients decreases time to disposition decision and total length of hospital stay. Conversely, time to treatment augments. There is need for the evaluation of ultrasound as an intervention in clinical trials to confirm these findings.

BACKGROUND: The issue of lower extremity amputation has been in the Colombian political agenda for its relationship with the armed conflict and antipersonnel mines. In 2015 the Colombian Ministry of Health published a national clinical practice guideline (CPG) for amputee patients. However, there is a need to design implementation strategies that target end-users and the context in which the CPG will be used. This study aims to identify users' perceptions about the barriers and facilitators for implementing the guideline for the care of amputee patients in a middle-income country such as Colombia. METHODS: Semi-structured interviews were conducted with 38 users, including patients, health workers, and administrative staff of institutions of the health system in Colombia. Individuals were purposively selected to ensure different perspectives, allowing a balance of individual positions. RESULTS: According to participants' perceptions, barriers to implementation are classified as individual barriers (characteristics of the amputee patient and professionals), health system barriers (resource availability, timely care, information systems, service costs, and regulatory changes), and barriers related to clinical practice guidelines (utility, methodological rigour, implementation flexibility, and characteristics of the group developing the guidelines). CONCLUSIONS: Our study advances knowledge on the perceived individual and health system barriers and facilitators for the implementation of the CPG for amputee patients in Colombia. Importantly, the governance, financial, and service delivery arrangements of the Colombian health system are determining factors in implementing CPGs. For example, the financial arrangements between the insurance companies and the health care provider institutions were identified as barriers for the implementation of recommendations related to the continuity and opportunity of care of patients with amputations. The design of implementation strategies that successfully address the individual behaviours and the contextual health systems arrangements may significantly impact the health care process for amputee patients in Colombia.

INTRODUCTION: Clinical practice guidelines (CPGs) are designed to improve the quality of care and reduce unjustified individual variation in clinical practice. Knowledge of the barriers and facilitators that influence the implementation of the CPG recommendations is the first step in creating strategies to improve health outcomes. The present systematic meta-review sought to explore the barriers and facilitators for the implementation of CPGs. METHODS: A search was conducted in the PubMed, Embase, Cochrane, Health System Evidence and International Guideline Library (G-I-N) databases. Systematic reviews of qualitative, quantitative or mixed-methods studies that identified barriers or facilitators for the implementation of CPGs were included. The selection of the title and abstract, the evaluation of the full text, extraction of the data and the quality assessment were carried out by two independent reviewers. To summarise the evidence, we grouped the barriers and facilitators according to the following contexts: political and social, health organisational system, guidelines, health professionals and patients. RESULTS: Overall, 25 systematic reviews were selected. The relevant barriers in the social-political context were the absence of a leader, difficulties with teamwork and a lack of agreement with colleagues. Relevant barriers in the health system were a lack of time, financial problems and a lack of specialised personnel. Barriers of the CPGs included a lack of clarity and a lack of credibility in the evidence. Regarding the health professional, a lack of knowledge about the CPG and confidence in oneself were relevant. Regarding patients, a negative attitude towards implementation, a lack of knowledge about the CPG and sociocultural beliefs played a role. Some of the most frequent facilitators were consistent leadership, commitment of the members of the team, administrative support of the institution, existence of multidisciplinary teams, application of technology to improve the practice and education regarding the guidelines. CONCLUSIONS: The barriers and facilitators described in this review are factors that influence the implementation of evidence in clinical practice. Knowledge of these factors should contribute to the development of a theoretical basis for the creation of CPG implementation strategies to improve professional practice and health outcomes for patients.

BACKGROUND: This study aimed to determine Consortium to Establish a Registry for Alzheimer's Disease (CERAD) Neuropsychological Assessment Battery total score diagnostic accuracy in the diagnosis of mild cognitive impairment (MCI) and dementia in familial Alzheimer's disease (FAD) with E280A mutation on presenilin-1 gene (PSEN1). METHODS: A cross-sectional study was conducted in a cohort of PSEN1 E280A carriers and non-carriers assessed between January 1995 and February 2013. During the first neuropsychological assessment, 76 were having dementia, 46 had MCI, and 1,576 were asymptomatic. CERAD cut-off points were established for MCI and dementia using a Receiver Operating Characteristics (ROC) analysis, and were further analyzed according to education level in two groups: low education level (eight years or less), and high education level (over eight years). RESULTS: The area under curve-ROC CERAD total score for dementia was 0.994 (95% CI = 0.989-0.999), and that for MCI was 0.862 (95% CI = 0.816-0.908). The dementia diagnosis cut-off point for the low education group was 54, (98.4% sensitivity, 92.6% specificity), and that for the high education group was 67 (100% sensitivity, 94.1% specificity). The MCI diagnosis cut-off point for the low education group was 66 (91.2% sensitivity, 56.4% specificity), and that for the high education group was 72 (91.7% sensitivity, 76.3% specificity). CONCLUSIONS: The CERAD total score is a useful screening tool for dementia and MCI in a population at risk of FAD.

INTRODUCTION: Studies that have compared the cognitive alterations of the children of parents with bipolar disorder (CPBD) versus the children of control parents (CCP), present heterogeneous results due to the studies' methodological differences, the age of the population studied, and the lack of standardisation of the measures used for the different neurocognitive domains. The objective was to compare the neurocognitive profile of CPBD versus CCP to observe if there are differences that could be proposed as possible endophenotypes of BD. RESULTS: A total of 107 individuals (51 CPBD, and 56 CCP) with ages between 6 and 16 (mean, 12.2±2.80) years of age were evaluated. Seventy-four point five percent of the CPBD group had some disorder compared to 67.9% of the CCP group. Tests such as letter-F phonemic verbal fluency, letter-S phonemic verbal fluency, overall F-A-S phonemic verbal fluency, story recall and retrieval, and Wisconsin perseverative errors showed a difference with a small effect size, but with a high degree of uncertainty. CONCLUSIONS: The CPBD did not have differences in their neurocognitive profile in comparison with CCP. Both groups have a high prevalence of psychopathology, which is a factor that could explain the lack of differences in neurocognitive performance.

OBJECTIVE: We aim to determine the prevalence of mental disorders in siblings of children with attention deficit hyperactivity disorder (ADHD), and to determine how psychosocial adversity factors relate to this psychopathology, in a low-middle income country (Colombia). METHODS: We evaluated subjects with ADHD diagnosed according to the DSM-5 criteria, one of their parents and one of their siblings (ages 8-19). We used the ADHD rating scale and a set of instruments to assess the presence of mental disorders as well as psychosocial adversity. RESULTS: We evaluated 74 trios formed by the index case with ADHD, one sibling and one of the parents. We found that 24.3% of the participating siblings also met the criteria for ADHD and another 24.3% for other psychiatric disorders. The risk of these siblings having ADHD increased further when one of the parents reported a history of ADHD. We also found that 28.3% of the families faced high levels of psychosocial adversity as per their scores in the Rutter Adversity Index. CONCLUSIONS: Siblings of subjects with ADHD showed a significant risk for ADHD and other mental disorders. That risk increased if a parent reported a history of ADHD and also when two or more psychosocial adversity factors were present. This study supports the importance of early detection in efforts to decrease the risk for other siblings.

INTRODUCTION: Mild Cognitive Impairment (MCI) is common in Parkinson's Disease (PD). Few studies have compared the Health-Related Quality of Life (HRQoL) in patients with and without MCI due to PD (PD-MCI), and its correlation to patients' subjective cognitive and communicative difficulties has not been explored. OBJECTIVE: We aimed to compare HRQoL in PD-MCI and PD without MCI (PD-nMCI), and explore its possible relationship to subjective cognitive and communicative complaints. METHODS: We included 29 PD-nMCI and 11 PD-MCI patients. The HRQoL was assessed with the Parkinson's Disease Questionnaire-39 (PDQ-39): its Cognition dimension was used as a measure of subjective cognitive complaints, its Communication dimension for subjective communicative complaints, and the summary index (PDQ-39 SI) as an indicator of HRQoL. Non-parametric partial correlations between the Cognition and Communication dimensions, and the adjusted PDQ-39 SI were conducted. RESULTS: PD-MCI patients had greater subjective cognitive and communicative complaints and worse HRQoL than PD-nMCI patients. In the PD-MCI group, both subjective cognitive and communicative complaints exhibited significant direct correlations with the adjusted HRQoL scores. CONCLUSIONS: HRQoL seems to be affected in PD-MCI, and it might be influenced by greater subjective cognitive and communicative complaints. Including patient-reported outcome measures of HRQoL, and providing cognitive and speech rehabilitation, as well as psychotherapeutic strategies to face these deficits can enhance the patient-centred approach in PD.

BACKGROUND: The SARS-CoV2 global pandemic impacted participants in the Alzheimer's Prevention Initiative (API) Autosomal Dominant Alzheimer's Disease (ADAD) clinical trial, who faced three stressors: 1) fear of developing dementia; 2) concerns about missing treatment; and 3) risk of SARS-CoV2 infection. OBJECTIVE: To describe the frequency of psychological disorders among the participants of the API ADAD Colombia clinical study, treated by a holistic mental health team during the COVID-19 pandemic. The extent of use of mental health team services was explored considering different risk factors, and users and non-users of these services were compared. METHODS: Participants had free and optional access to psychology and psychiatry services, outside of the study protocol. Descriptive statistics was used to analyze the frequency of the mental health difficulties. A multivariable logistic regression model has been used to assess associations with using this program. RESULTS: 66 participants were treated by the Mental Health Team from March 1, 2020, to December 31, 2020. Before and after the start of the pandemic, the most common psychological problems were anxiety (36.4% before, 63.6% after) and depression (34.8% before, 37.9% after). 70% of users assisted by psychology and 81.6% of those assisted by psychiatry felt that the services were useful for them. Female sex, depression, and anxiety before the pandemic were positively associated with being assisted by either psychology or psychiatry, while the association with hyperlipidemia was negative. CONCLUSIONS: A holistic mental health program, carried out in the context of a study, could mitigate psychopathology during pandemics such as COVID-19.

OBJECTIVE: To classify the staff of two reference institutions for COVID-19 care in Antioquia according to the intensity of anxiety and depression symptoms, and to determine the factors associated with these classes. METHODS: Cross-sectional study in which the GAD-7, PHQ-9, fear of COVID-19, and the Copenhagen Burnout scale were used. Latent class analysis was performed to identify the classes, and the factors associated with these were determined using multinomial logistic regression. RESULTS: 486 people participated. The three-class model had the best fit: class I with low scores on the scales; class II with mild degrees of anxiety and depression, and intermediate levels of fear of COVID-19 and perceived stress; and class III with moderate and severe degrees of anxiety, depression, and perceived stress. The factors associated with belonging to class III were age (ORâ¯=â¯0.94; 95%CI, 0.91-0.96), change of residence to avoid exposing relatives (ORâ¯=â¯4.01; 95%CI, 1.99-8.09), and a history of depressive disorder (ORâ¯=â¯3.10; 95%CI, 1.27-7.56), and anxiety (ORâ¯=â¯5.5; 95%CI, 2.36-12.90). Factors associated with class II were age (ORâ¯=â¯0.97; 95%CI, 0.95-0.99), history of depressive disorder (ORâ¯=â¯3.41; 95%CI, 1.60-7.25), living with someone at risk of death from COVID-19 (ORâ¯=â¯1.86; 95%CI, 1.19-2.91), family member being healthcare staff (ORâ¯=â¯1.58; 95%CI, 1.01-2.47), and change of residence to avoid exposing relatives (ORâ¯=â¯1.99; 95%CI, 1.11-3.59). CONCLUSIONS: Three classes of participants were obtained, two of them with anxiety and depression symptoms. Younger age and a history of mental disorder were factors associated with the two classes of symptomatic patients; other factors may be causes or consequences of the symptoms.

Handgrip strength is a robust indicator of the biological health of children and adolescents. Objecti ves: to identify the anthropometric characteristics and body composition related to handgrip stren gth, and to describe the main characteristics of the protocols used for its evaluation. METHODOLOGY: A scoping review was developed; the search was carried out in 1.) Medline; 2.) Web of Science; 3.) Science Direct; 4.) Scielo; and 5.) EBSCO's Sportdiscus. Original investigations were included if they have handgrip strength data, anthropometric characteristics, and body composition. RESULTS: 59 reports published between 2005 and 2020 were selected. Among them, nutritional classification was the most studied characteristic (n = 25; 42.3%), followed by body mass index (n = 23; 38.9%). In 47.5% (28 reports), the number of tests performed on each individual to estimate the handgrip strength value was not clear. The dynamometer brand Takei Scientific Instrument Co. Ltd. was the most used, with 49.2 %. The most widely used indicator was absolute handgrip (86.4%, 51 reports). CONCLUSIONS: There is a wide variety of protocols used for handgrip strength assessment with va riations in body position, arm and hand selection, number of repetitions, and intervals between measurements. A proportional pattern of values was found between absolute handgrip strength and body mass index, Σ skinfolds, however, when adjusted by mass (relative handgrip strength), the relationship is inverse.

OBJECTIVE: The objective of this study is twofold: i) to estimate the normative values for handgrip strength and relative handgrip strength, specific to sex and age, for Colombian children and adolescents from 6 to 17 years of age using quantile regression models and ii) to compare the normative values for handgrip strength and relative handgrip strength in Colombian children and adolescents with those in children and adolescents in different countries. METHOD: This was a cross-sectional analysis of a sample of 2647 youngsters. Handgrip strength was evaluated with a TKK 5101 digital dynamometer (Takei Scientific Instruments Co., Ltd., Tokyo, Japan). The relative handgrip strength was estimated according to weight in kilograms. The normative values were estimated to handgrip strength and relative handgrip strength through quantile regression models for the percentiles P5, P10, P25, P50, P75, P90, and P95 developed independently for each sex. All analyses were adjusted for the expansion factor. RESULTS: The values for handgrip strength were considerably higher in males than in females in all age ranges. Additionally, as age increased for both sexes, the values for handgrip strength increased. The percentiles by sex and age for relative handgrip strength show for males a proportional increase according to age; for females, this did not occur. CONCLUSIONS: When making comparisons with international studies, variability is observed in the methodologies used to evaluate handgrip strength and estimation methods, which could influence the discrepancies between the different reports.

BACKGROUND: Alzheimer's disease (AD) is a neurodegenerative disease that causes a gradual loss of cognitive functions and limits daily activities performance. Early diagnosis of AD is essential to start timely treatment. This study aimed to validate the Uniform Data Set neuropsychological battery version 3.0 (UDS 3.0) in a Colombian cohort. METHODS: This study is a cross-sectional type, consecutive, incidental, with 143 persons, divided into two groups: 48 diagnosed AD cases and 95 healthy controls, between the ages of 50 and 80+, and between 1 and 19+ years of education. RESULTS: The results indicate differences between the control group and the AD group in most battery tests. A significant correlation was found between the Montreal Cognitive Assessment (MoCA), Multilingual Naming Test (MINT), Craft Story, Benson Figure Test, P-word and F-word Phonemic Fluency Test, and their respective reference tests. Cutoff points were found based on the Youden index for each sub-test. The results indicate that all sub-tests are above the reference line of the ROC curve. CONCLUSION: The use of the UDS 3.0 in Colombia would help improving clinical diagnostic routes because of its high accuracy and high correlation with tests that measure general impairment; it has good sensitivity and specificity, and it can be a useful tool for AD.

Conclusión: La felicidad es un fenómeno multicausal que en los adultos mayores hace parte del resultado de la interacción de variables y decisiones históricas, a nivel político, económico y social.
RESUMEN
INTRODUCTION: The offspring of bipolar parents (BO) is a high-risk population for inheriting the bipolar disorder (BD) and other early clinical manifestations, such as sleep disturbances. OBJECTIVE: To compare the presence of psychiatric disorders and sleep disturbances of BO versus offspring of control parents (OCP). METHODS: A cross-sectional analytical study was conducted that compared BO versus OCP. The participants were assessed using valid tools to determine the presence of psychiatric symptoms or disorders. The "Sleep Evaluation Questionnaire" and "School Sleep Habits Survey" were used to determine sleep characteristics and associated factors. Sleep records (7-21 days) were also obtained by using an actigraphy watch. RESULTS: A sample of 42 participants (18 BO and 24 OCP) was recruited. Differences were found in the presentation of the psychiatric disorder. The BO group showed a higher frequency of major depression disorder (MDD; Pâ¯=â¯.04) and Disruptive Mood Dysregulation Disorder (DMDD; Pâ¯=â¯.04). The OCP group showed a higher frequency of Attention Deficit and Hyperactivity Disorder (ADHD; Pâ¯=â¯.65), and Separation Anxiety Disorder (SAD; Pâ¯=â¯.46). Differences were also found in sleep by using subjective measurements. Compared to the OCP group, BO had a worse perception of quality of sleep (Pâ¯=â¯.02), a higher frequency of nightmares (Pâ¯=â¯.01), a shorter total sleep time, and a higher sleep latency. Nevertheless, no differences were found between groups in the actigraphy measurements. CONCLUSIONS: The BO group had a higher frequency of Mood Disorders, and at the same time a higher number of sleep disturbances in the subjective measurements. It is possible that there is an association between mood symptoms, sleep disturbances, and coffee intake. No differences were found in the sleep profile by using actigraphy.

INTRODUCTION: Lithium treatment of bipolar disorder (BD) has been associated with less cognitive impairment and fewer changes in structural brain anatomy compared to other treatments. However, the studies are heterogeneous and few assess whether these effects are related. The objective of this study was to evaluate and relate cognitive performance and structural neuroanatomy in patients treated with and without lithium. METHODS: Cross-sectional study that included 48 subjects with BD-I, of which 22 were treated with lithium and 26 without lithium. Performance was assessed on Wechsler III (WAIS III), TMT A and B (Trial Making Test) neuropsychological tests, California verbal learning test (CVLT), Rey complex figure test and Wisconsin card sorting test. Brain structures obtained by magnetic resonance imaging (MRI) were evaluated. The standardised mean difference (SMD) between both groups was calculated, adjusted for confounding variables using a propensity score, and the Spearman correlation coefficient (ρ) was used to assess the relationship between cognitive performance and neuroanatomical regions. RESULTS: Compared to the group without lithium, the group with lithium had fewer perseverative errors in the Wisconsin test (SMDâ¯=â¯-0.69) and greater left and right cortical areas (SMDâ¯=â¯0.85; SMDâ¯=â¯0.92); greater surface area in the left anterior cingulate (SMDâ¯=â¯1.32), right medial orbitofrontal cortex (SMDâ¯=â¯1.17), right superior frontal gyrus (SMDâ¯=â¯0.82), and right and left precentral gyrus (SMDâ¯=â¯1.33; SMDâ¯=â¯0.98); greater volume of the right amygdala (SMDâ¯=â¯0.57), right hippocampus (SMDâ¯=â¯0.66), right putamen (SMDâ¯=â¯0.87) and right thalamus (SMDâ¯=â¯.67). In the lithium group, a correlation was found with these errors and the thickness of the left precentral gyrus (ρâ¯=â¯-0.78), the volume of the right thalamus (ρâ¯=â¯-0.44), and the right amygdala (ρâ¯=â¯0.6). CONCLUSIONS: The lithium group had better cognitive flexibility and greater dimension in some frontal and subcortical cortical regions. Furthermore, there was a moderate to high correlation between performance in this executive function and the thickness of the right precentral gyrus, and the volumes of the thalamus and the right amygdala. These findings could suggest a neuroprotective effect of lithium.

To determine the explanatory capacity of pain metacognitions and beliefs over the functionality, coping and pain intensity, following the Model of Self-Regulatory Executive Functions (S-REF) in a sample of women with ï¬bromyalgia from Medellín and its Metropolitan Area. Method: Metacognitions Scale on Symptom Control, Pain Self-eï¬cacy Questionnaire, Chronic Pain Catastrophizing Scale, Chronic Pain Coping Questionnaire, WHODAS 2.0 Scale, and Pain Intensity Numerical Scale. The sample was represented by 108 women between 24 and 60 years old with a diagnosis of ï¬bromyalgia. A modeling process was carried out through an analysis of structural equations. Results: The ï¬nal model fails to ï¬t. Despite this, the analysis suggests that negative metacognitions and pain self-eï¬cacy have an eï¬ect over the tendency to catastrophizing. The latter and the pain self-eï¬cacy are the main mediators in the eï¬ects of functionality. The intensity of pain is not determined by the metacognitions related to it.
Determinar la capacidad explicativa de las metacogniciones y las creencias del dolor sobre la funcionalidad, el afrontamiento y la intensidad del dolor, siguiendo el Modelo de Funciones Ejecutivas de Autorregulación (FEAR) en una muestra de mujeres con ï¬bromialgia de Medellín y su Área Metropolitana. Método: Se aplicaron: Escala de Metacogniciones acerca del Control de Síntomas, Cuestionario de Autoeï¬cacia al Dolor, Escala de Catastroï¬zación al Dolor Crónico, Cuestionario de Afrontamiento al Dolor Crónico, Escala WHODAS 2.0 y Escala numérica de la intensidad del dolor. La muestra estuvo representada por 108 mujeres entre 24 y 60 años con diagnóstico de ï¬bromialgia. Se realizó un proceso de modilización por medio de un análisis de ecuaciones estructurales. Resultados: El modelo ï¬nal no logra ajustarse. A pesar de ello, el análisis sugiere que las metacogniciones negativas y la autoeï¬cacia al dolor tienen un efecto sobre la tendencia a la catastroï¬zación. Esta última y la autoeï¬cacia al dolor son las principales mediadoras en los efectos de funcionalidad. La intensidad del dolor no está determinada por las metacogniciones relacionadas con este.
RESUMEN
INTRODUCTION: Studies that have compared the cognitive alterations of the children of parents with bipolar disorder (CPBD) versus the children of control parents (CCP), present heterogeneous results due to the studies' methodological differences, the age of the population studied, and the lack of standardisation of the measures used for the different neurocognitive domains. The objective was to compare the neurocognitive profile of CPBD versus CCP to observe if there are differences that could be proposed as possible endophenotypes of BD. RESULTS: A total of 107 individuals (51 CPBD, and 56 CCP) with ages between 6 and 16 (mean, 12.2±2.80) years of age were evaluated. Seventy-four point five percent of the CPBD group had some disorder compared to 67.9% of the CCP group. Tests such as letter-F phonemic verbal fluency, letter-S phonemic verbal fluency, overall F-A-S phonemic verbal fluency, story recall and retrieval, and Wisconsin perseverative errors showed a difference with a small effect size, but with a high degree of uncertainty. CONCLUSIONS: The CPBD did not have differences in their neurocognitive profile in comparison with CCP. Both groups have a high prevalence of psychopathology, which is a factor that could explain the lack of differences in neurocognitive performance.
RESUMEN
OBJECTIVE: We aim to determine the prevalence of mental disorders in siblings of children with attention deficit hyperactivity disorder (ADHD), and to determine how psychosocial adversity factors relate to this psychopathology, in a low-middle income country (Colombia). METHODS: We evaluated subjects with ADHD diagnosed according to the DSM-5 criteria, one of their parents and one of their siblings (ages 8-19). We used the ADHD rating scale and a set of instruments to assess the presence of mental disorders as well as psychosocial adversity. RESULTS: We evaluated 74 trios formed by the index case with ADHD, one sibling and one of the parents. We found that 24.3% of the participating siblings also met the criteria for ADHD and another 24.3% for other psychiatric disorders. The risk of these siblings having ADHD increased further when one of the parents reported a history of ADHD. We also found that 28.3% of the families faced high levels of psychosocial adversity as per their scores in the Rutter Adversity Index. CONCLUSIONS: Siblings of subjects with ADHD showed a significant risk for ADHD and other mental disorders. That risk increased if a parent reported a history of ADHD and also when two or more psychosocial adversity factors were present. This study supports the importance of early detection in efforts to decrease the risk for other siblings.
