Characteristics of anterior segment structure in first-degree relatives of patients with primary angle-closure glaucoma / 国际眼科杂志(Guoji Yanke Zazhi)

AIM: To investigate the characteristics of anterior segment structure in first-degree relatives of patients with primary angle-closure glaucoma(PACG).METHODS: A total of 48 first-degree relatives of PACG patients aged 40-60 who were treated in the Affiliated Eye Hospital of Nanchang University from September 2020 to October 2022 were selected as the observation group. Additionally, 40 cases(40 eyes)of healthy individuals without glaucoma and family history of glaucoma at the same age group were collected as the control group. They were divided into younger group(40-49 years old)and elder group(50-60 years old). All subjects were examined with ultrasound biomicroscopy(UBM)and were measured using camera measure software. The parameters mainly included anterior chamber depth(ACD), anterior chamber area(ACA), anterior chamber width(ACW), anterior segment depth(ASD), angle open distance(AOD500), trabecular iris angle(TIA), trabecular iris area(TISA500), lens vault(LV), iris curve(IC), iris thickness(IT500), scleral ciliary process angle(SCPA), and iris ciliary process distance(ICPD).RESULTS: ACD, ACA, AOD500, TISA500 and TIA in the observation group were lower than those of the control group, and LV and IC were higher than those of the control group(all P<0.05). ACD, ACA, AOD500, TISA500, and TIA of the elder group were lower than those in the age-matched control group, while LV and IC were larger than those of the age-matched control group(all P<0.05). ACD, AOD500, TISA500, and TIA of the younger observation group were smaller than those of the age-matched control group, but LV and IC were significantly larger than those of the age-matched control group(all P<0.05). ACD, ACA, AOD500, TISA500 and TIA of the elder observation group were significantly lower than those of the younger observation group, and LV and IC were significantly larger than those of the younger observation group(all P<0.05). There was a difference in the distribution of ACD between the observation group and the control group(P<0.05), and the proportion of moderate to severe shallow anterior chambers was 10 times that of the control group. Correlation analysis showed that TISA500 was positively correlated with ACD and ACA, and negatively correlated with LV and IC, and TISA500 was mainly influenced by LV. IC had a positive correlation with LV and a negative correlation with ACD and ACA.CONCLUSION: First-degree relatives of PACG with normal axial length have a high risk of angle closure. The anterior segment structures of first-degree relatives of PACG are more crowded than normal individuals, and the lens forward shift may be the initial influencing factor for narrow angle.

¿Es diferente la conectividad estructural en niños y adolescentes familiares de pacientes con trastorno bipolar? Una revisión narrativa según estudios con DTI

Introducción: El trastorno afectivo bipolar (TAB) se ha asociado con una disminución de la integridad de la sustancia blanca. Los estudios con imágenes con tensor de difusión (DTI) han permitido elucidar con una mayor calidad estos cambios. Debido a la gran heredabilidad del TAB, se han realizado estudios en familiares de pacientes con TAB acerca de la integridad de la sustancia blanca, y se ha encontrado que la conectividad estructural también puede estar afectada. Dicha alteración se ha propuesto como un potencial biomarcador de vulnerabilidad a este trastorno. Sin embargo, los estudios en niños y adolescentes son pocos. Objetivo: Revisar la literatura sobre los cambios en la integridad de la sustancia blanca determinados mediante DTI en niños y adolescentes con alto riesgo. Resultados: Se describe la conectividad estructural cerebral en la población pediátrica en estudios que utilizaron DTI. Se describen los cambios en el proceso de mielinización desde su evolución dentro del neurodesarrollo normal hasta los hallazgos en la anisotropía fraccional (AF) en pacientes con TAB y los familiares en alto riesgo. Conclusiones: Los estudios demuestran que tanto pacientes con TAB como sus familiares en riesgo presentan disminución de la AF en regiones cerebrales específicas. Los estudios en niños y adolescentes con riesgo familiar de TAB señalan una AF reducida en tractos axonales implicados en funciones emocionales y cognitivas. La disminución de la AF puede considerarse como un biomarcador de vulnerabilidad al TAB.

Introduction: Bipolar disorder (BD) has been associated with a decrease in white matter integrity. Diffusion tensor imaging (DTI) studies have enabled these changes to be elucidated with higher quality. Due to BD's high heritability, some studies have been conducted in relatives of BD patients looking at white matter integrity, and have found that structural connectivity may also be affected. This alteration has been proposed as a potential BD biomarker of vulnerability. However, there are few studies in children and adolescents. Objective: To conduct a review of the literature on changes in white matter integrity determined by DTI in high-risk children and adolescents. Results: Brain structural connectivity in the paediatric population is described in studies using DTI. Changes in the myelination process from its evolution within normal neurodevelopment to the findings in fractional anisotropy (FA) in BD patients and their high-risk relatives are also described. Conclusions: Studies show that both BD patients and their at-risk relatives present a decrease in FA in specific brain regions. Studies in children and adolescents with a high risk of BD, indicate a reduced FA in axonal tracts involved in emotional and cognitive functions. Decreased FA can be considered as a vulnerability biomarker for BD.

Structural network changes in first-degree relatives of depressed patients and their correlation with the onset of depression / 中华神经科杂志

Objective:To explore the structural brain network changes in healthy first-degree relatives of depressed patients and their relationship with depressive episodes.Methods:Prospectively, 200 healthy first-degree relatives of depressed patients admitted to Jiangsu University Hospital from May 2017 to June 2018 were collected. Meanwhile, 50 matched healthy controls without family history of depression (HC/FH-) were collected by questionnaire in the nearby community as study subjects. All study subjects underwent systemic magnetic resonance imaging scans and assessment of relevant scales after enrollment, followed by longitudinal follow-up (every 3 months) for up to 3 years. The diagnostic and statistical manual of mental disorders, 4th edition, structured interview was used to assess whether the subjects became depressed during the follow-up period. First-degree relatives who experienced depression during follow-up were included in the group of first-degree relatives who experienced depression (DD/FH+), whereas first-degree relatives who did not experience depression were included in the group of first-degree relatives who did not experience depression (HC/FH+). Subjects′ depression severity and whether they experienced major stressful life events were assessed by the 24-item Hamilton Depression Rating Scale (HDRS) and the Holmes and Rahe Social Readjustment Rating Scale, respectively. Correlations between subjects′ brain structural networks and HDRS scores were explored based on Pearson correlation analysis. Logistic regression models were constructed to investigate the predictive efficacy of brain structural network attributes on depression.Results:Significant group differences existed in the HC/FH- group (50 cases), HC/FH+ group (115 cases), and DD/FH+ group (21 cases) in feeder connectivity (17.62±1.34, 17.03±1.39, 15.82±1.12, F=13.63, P<0.001), global efficiency (0.24±0.03, 0.23±0.03, 0.22±0.03, F=4.73, P=0.010), right insula node efficiency (0.20±0.02, 0.21±0.01, 0.20±0.01, F=4.62, P=0.011), left hippocampal node efficiency (0.27±0.01, 0.27±0.01, 0.24±0.02, F=18.56, P<0.001), and left amygdala node efficiency (0.24±0.02, 0.24±0.02, 0.23±0.01, F=3.40, P=0.036). Logistic regression models showed feeder connectivity ( OR=0.55, 95% CI 0.38-0.78, P=0.001) and left hippocampal nodal efficiency ( OR=0.58, 95% CI 0.40-0.81, P<0.001) predicted the occurrence of final depression and had good predictive efficacy with an area under the curve of 0.75, 0.78, respectively. Correlation analysis showed that feeder connectivity ( r=-0.58, P=0.006) and left hippocampal node efficiency ( r=-0.60, P=0.004) at baseline in the DD/FH+ group correlated with their HDRS scores at the first follow-up. Conclusion:Among healthy first-degree relatives of depressed patients, those who exhibit decreased feeder connectivity and left hippocampal nodal efficiency are susceptible to developing this disease.

Characteristics of auditory steady-state response in first-degree relatives of schizophrenic patients under eye-open/closed state / 中华行为医学与脑科学杂志

Objective:To study the effect of eye-open/closed state on 40 Hz auditory steady state response (ASSR) in first-degree relatives of schizophrenia.Methods:Thirty-eight first-degree relatives of schizophrenic patients treated in Shanghai Mental Health Center from March 2010 to October 2011 were selected, and 31 healthy controls were recruited in the same period. All subjects were assessed with schizotypal personality questionnaire (SPQ). The 40 Hz EEG ASSR signals lasting for 3 min under open and closed eyes of all subjects were sequentially collected.Event-related spectrum perturbation (ERSP) and intertribal phase coherence (ITC) were used to evaluate ASSR. SPSS 22.0 software was used for statistical analysis. Two-way analysis of variance was used to compare ITC and ERSP between the two groups under open and closed eyes. Spearman correlation analysis was used to analyze the correlation between each measurement.Results:ITC in group main effect and group×the eye open/closed interaction effect were not significant (both P>0.05), but the main effect of eye-open and eye-closed was significant ( F(1, 67)=10.61, P=0.002). In the healthy control group, the ITC in eye-open state was significantly higher than that in eye-closed state ( P=0.014), and in the first-degree relatives group, the ITC in eye-open state was higher than that in eyes closed state ( P=0.039). ERSP in the main effect of eye-open and eye-closed ( F(1, 67)=0.195, P=0.660), group main effect ( F(1, 67) =0.627, P=0.431), group × the eye-open/closed interaction effect ( F(1, 67)= 1.034, P=0.313) was not significant. Spearman correlation analysis showed that there was no correlation between ERSP (eye open: r=-0.260, P=0.210; eye closed: r=-0.318, P=0.122), ITC (eye open: r=-0.248, P=0.232; eye closed: r=-0.260, P=0.209) and SPQ score in the healthy control group. There was also no correlation between ERSP (eye open: r=-0.387, P=0.226; eye closed: r=-0.363, P=0.238) or ITC (eye open: r=0.126, P=0.485; eye closed: r=0.096, P=0.595) and SPQ score in the first-degree relatives group of schizophrenia. Conclusion:The regulation pattern of 40 Hz ASSR in schizophrenic first-degree relatives is not significantly impaired in the eye-open/closed state, suggesting that the open/closed regulation pattern of 40 Hz ASSR may not be a potential marker for predicting the genetic high-risk prognosis of schizophrenia.

Research of first-degree relatives of keratoconus / 国际眼科杂志(Guoji Yanke Zazhi)

@#Keratoconus(KC)is a progressive disease characterized by gradual corneal thinning and ectasia, resulting in irregular astigmatism, myopia, and mild to severe visual impairment. Although the pathogenesis of KC is still unclear, twin studies and family-based studies have identified that the occurrence of KC is closely related to genetic factors. First-degree relatives of KC patients including their parents, siblings and offspring are very important for the family aggregation analysis and polygenic analysis of diseases. This review summarized the current situation of clinical and genetic research about first-degree relatives of KC patients, hoping to deepen the understanding of clinical manifestations and genetic characteristics of first-degree relatives of KC, and to provide new ideas for exploring the role of genetic and environmental factors in the pathogenesis of KC.

Enfermedad cardiovascular subclínica en familiares de mujeres con síndrome de ovario poliquístico y su asociación con la resistencia a la insulina / Subclinical Cardiovascular Disease in Relatives of Women with Polycystic Ovary Syndrome and its Association with Insulin Resistance

Introducción: Se ha demostrado que los familiares de mujeres con síndrome de ovario poliquístico tienen mayor frecuencia de factores de riesgo cardiovascular, tales como la resistencia a la insulina, la diabetes mellitus tipo 2, la dislipidemia y la hipertensión arterial. Por ende, estas personas presentan un mayor riesgo de desarrollar enfermedad cardiovascular. Objetivo: Determinar la frecuencia de enfermedad cardiovascular subclínica en familiares de primer grado de mujeres con y sin síndrome de ovario poliquístico y su relación con la resistencia a la insulina. Métodos: Se realizó un estudio descriptivo transversal en 36 familiares de primer grado de mujeres con el síndrome de ovario poliquístico e igual cantidad en familiares de mujeres sin la enfermedad. Ninguno de los miembros de ambos grupos tenía antecedentes de diabetes mellitus, prediabetes, dislipidemia e hipertensión arterial, ni obesidad. Para llevar a cabo la comparación de los resultados de las pruebas realizadas fueron pareados a razón de 1:1, por edad ± 5 años, parentesco, sexo e índice de masa corporal. Resultados: Con enfermedad cardiovascular subclínica hubo 21 familiares, 15 del grupo de estudio (71,4 por ciento) y del grupo control el 28,6 por ciento, (p < 0,05). De la totalidad de familiares del grupo de estudio, con resistencia a la insulina el 65,0 por ciento presentó enfermedad cardiovascular subclínica. En el grupo control, ninguno de los pacientes con insulinemia en ayunas normal tuvo enfermedad cardiovascular subclínica. Conclusiones: La enfermedad cardiovascular subclínica es más frecuente en los familiares de mujeres con síndrome de ovario poliquístico y la resistencia a la insulina se asocia de forma significativa a este padecimiento en ambos grupos(AU)

Introduction: Relatives of women with polycystic ovary syndrome have been show to present a higher frequency of cardiovascular risk factors, such as insulin resistance, type 2 diabetes mellitus, dyslipidemia and arterial hypertension. Therefore, these people have a higher risk for developing cardiovascular disease. Objective: To determine the frequency of subclinical cardiovascular disease in first-degree relatives of women with and without polycystic ovary syndrome and its relationship with insulin resistance. Methods: A cross-sectional and descriptive study was carried out with 36 first-degree relatives of women with polycystic ovary syndrome and with the same number of relatives of women without the disease. None of the members of both groups had a history of diabetes mellitus, prediabetes, dyslipidemia, high blood pressure, or obesity. To carry out the comparison of the results of the tests carried out, they were matched at a 1: 1 ratio, by age ± 5 years, relationship, sex and body mass index. Results: There were 21 relatives with subclinical cardiovascular disease, 71.4 percent of which belonged to the study group, why 28.6 percent belonged to the control group (P < 0.05). Of the total family members of the study group, with insulin resistance, 65.0 percent had subclinical cardiovascular disease. In the control group, with normal fasting insulinemia, none has subclinical cardiovascular disease. Conclusions: Subclinical cardiovascular disease is more frequent in the relatives of women with polycystic ovary syndrome, while insulin resistance is significantly associated with this condition in both groups(AU)

Screening and analysis of gastric cancer in large-scale natural population in Wuxi / 中华消化内镜杂志

Objective:To explore the screening scheme of gastric cancer in large-scale natural population in Wuxi.Methods:From December 2016 to December 2019, 105 865 residents of 19 communities (villages) in six streets of Xinwu District, Wuxi were randomly enrolled in this study by random number table. A household epidemiological questionnaire survey was conducted among 50 063 target population subjects (aged 40-69), and then, respondents were divided into four categories, category Ⅰ: HP (-), PG (-); category Ⅱ: HP (+ ), PG (-); category Ⅲ: HP (+ ), PG (+ ); category Ⅳ: HP (-), PG (+ )according to the serological Helicobacter pylori ( HP) antibodies and pepsinogen (PG) test results. People in category Ⅲ and Ⅳ were all selected into group C and group D respectively, then individuals 3 times of group D were randomly selected from category Ⅰ to assign to group A, and individuals 3 times of group C from category Ⅱwere assigned to group B in the same way. Remaining individuals in category Ⅰ and Ⅱ who had first-degree family history of gastric cancer were also included in group A and group B, respectively. Endoscopic and pathological examination were performed on the above enrolled subjects for high grade intraepithelialneoplasia (HGIN), early gastric cancer and gastric cancer. Results:Of the 50 063 target subjects, 31 508 questionnaires were finally collected, with a participation rate of 62.9%. A total of 19 745 people were tested for serology, and the participation rate was 39.4% (19 745/50 063). Serological results showed that there were 11 152 people (56.48%) in category Ⅰ, 8 170 (41.38%) in category Ⅱ, 124 (0.63%) in category Ⅲ, and 299 (1.51%) in category Ⅳ. According to the exclusion criteria and principle of voluntariness, 3 400 individuals were candidates to undergo gastroscopy. Finally, a total of 2 389 people came to the hospital for gastroscopy, 1 263 in group A, 814 in group B, 86 in group C and 226 in group D, with an overall response rate of 70.3% (2 389/3 400), target population participation rate of 4.8% (389/50 063), and the overall population participation rate of 2.3% (2 389/105 865). In the 2 389 cases, there were 32 cases (1.34%) of HGIN and gastric cancer by gastroscopy and biopsy pathology, among which 1 case (3.125%) aged 40-49, 9 (28.125%) aged 50-59, and 22 (68.750%) aged 60-69. Among the 32 cases, 25 cases (78.13%)were pathologically confirmed as having HGIN or early gastric cancer by endoscopic submucosal dissection or surgical operation. By eliminating 810 people (including 3 gastric cancer) without first-degree family history with gastric cancer in group Ⅰ and Ⅱ, and increasing the gastroscopy screening age to 50 years (exluding 214 people aged 40-49, including 1 gastric cancer), the number of people who should undergo gastroscopy could be reduced from 2 389 to 1 365, and 28 cases of HGIN or gastric cancer were still detected, including 22 HGIN or early gastric cancer.Conclusion:Gastroscopy after the screening with epidemiological, serological tests, age and first-degree relative with gastric cancer family history is suitable for gastric cancer screening in Wuxi. Based on Chinese national conditions, a new community gastric cancer screening program is recommended in Wuxi considering cost-effectiveness, which includes those over 50 years old, serological PG (+ ) and first-degree relatives with family history of gastric cancer.

Ultrasound evaluation of the carotid artery elasticity in the first-degree relatives of patients with type 2 diabetes mellitus by RF-data based quantitative analysis on vessel stiffness / 中华超声影像学杂志

Objective:To evaluate the carotid artery elasticity in the first-degree relatives of patients with type 2 diabetes mellitus.Methods:Ninety first-degree relatives of patients with type 2 diabetes who received treatment in the Department of Endocrinology of Henan Provincial People′s Hospital from October 2020 to June 2021 were randomly selected and designated as having a positive family history. Depending on the parental history of diabetes they were divided into three groups: 31 cases of family history positive in father (F), 31 cases of family history positive in mother (M) and 28 cases of family history positive in both father and mother (B). Thirty cases with matched age, height and weight without any history of diabetes, hypertension, hyperlipidemia and coronary atherosclerotic heart disease in their parents designated as control group were taken for comparison. Real-time intima-media thickness (RIMT) and R-VQS were employed to evaluate common carotid intima-media thickness (IMT), distance (Dist), diameter (Diam), hardness coefficient (HC) and pulse wave velocity (PWV). The differences among the groups were compared.Results:①There was no statistical significance in Diam among the four groups ( P>0.05). ②Compared with the control group, the IMT, PWV and HC in subjects with positive family history were increased, while Dist was decreased ( P<0.05). ③Paired comparison of the subjects with positive family history: the IMT, PWV and HC in B group were higher than in F and M group, and Dist was lower than in F and M group ( P<0.05). The PWV and HC in M group were higher than in F group, and Dist was lower than in F group ( P<0.05). There was no statistical significance in IMT between the F and M groups ( P>0.05). Conclusions:Carotid artery stiffness in the cases with positive family history is significantly higher than the control group. The decrease of carotid elasticity in B group is the most serious, M group takes the second place, while the F group is the least.

Epidemiological investigation and analysis of the family history of cancer in 418 patients with lung cancer / 公共卫生与预防医学

Objective To understand the prevalence of family cancer history among lung cancer patients. Methods The family cancer history of 418 patients with lung cancer was investigated by a face-to-face survey in Bazhong area according to the " Questionnaire on Family History and Medical History of Population Diseases". Results The positive rates of family history of cancer and lung cancer in the 418 patients with lung cancer were 36.12% (151/418) and 28.47% (119/418), respectively. There was no statistical difference in the positive rates between the two (P>0.05). Among the patients' family members, the number of cancer-positive people was mainly 3 or less. The higher the number, the lower the probability (P<0.05). The positive rates of family history of cancer and lung cancer in first-degree relatives were significantly higher than those of second-degree and third-degree relatives (P<0.05). Conclusion Targeted health education for cancer patients and their families, especially health education for first-degree relatives, may help improve the early diagnosis of lung cancer patients.

Assessment of plasma blood sugar level in first degree relatives of known type 2 diabetes patients: a descriptive study from Maharashtra, India

Background: There is steady increase in the prevalence of diabetes mellitus from 0.73% to current 2.4% in rural and 4.0% to 11.6% in urban areas. Familial clustering of diabetes may support a genetic predisposition to diabetes. With increase in the prevalence of diabetes there is increase in number of first degree relative as well, thus an increased risk of developing diabetes, will also increase. To study the plasma glucose levels in First-degree relatives of family member of type 2 diabetic patients was the objective of the present study.Methods: It is a descriptive observational study with 1020 individuals serially coming to our outpatient Department for Pre-employment Medical Health Check Up Annual Health Check Up were selected. These individuals have been enrolled for the study and their family history of diabetes was noted, their sugar levels and their lipid levels were estimated and their body mass index was calculated. The data thus collected and analyzed with excel.Results: 184 (18%) individuals were FDRs, were as 836 (82%) individuals were Non-FDRs. There were 754 (74%) males [131(17%) FDR and 623(83%) Non-FDR], were as 213 (26%) females [53(20%) FDR and 213(80%) Non-FDR], 61(6%) individuals were having Diabetic Mother, 91(9%) individuals had Diabetic Father and 32(3%) were those in whom both the Parents were Diabetic. It was found that maternal history has strong association for getting abnormal BSL levels as compared to a diabetic father as the RR of 9.82 (95% 4.84 to 19.95) in individuals with mother being diabetic, and RR of 1.54(95% 0.68 to 3.87) of father being diabetic.Conclusions: Family history of diabetes, maternal history of diabetes and history of both the parents having diabetes are risk factors for diabetes in FDRs

Riesgo de trastorno por déficit de atención e hiperactividad y otros trastornos psiquiátricos de los hermanos de pacientes con TDAH / Risk of Attention Deficit/Hyperactivity Disorder (ADHD) and Other Psychiatric Disorders in Siblings of ADHD Probands

RESUMEN Introducción: El trastorno por déficit de atención con hiperactividad (TDAH) ocurre con mayor frecuencia en familiares de primer grado. Se cree que el riesgo no solo es específico de este trastorno, sino también de otras psicopatologías. Estudiar a los hermanos de pacientes con TDAH es un campo interesante porque comparten factores ambientales comunes. Métodos: Revisión narrativa de la literatura. Se realizó una búsqueda bibliográfica en las bases de datos PubMed y PsychNet, y se seleccionaron los artículos relacionados con el tema sin límites de fecha de publicación o diseño. Resultados: Los hermanos de pacientes con TDAH tienen mayor posibilidad de sufrir el mismo trastorno en comparación con controles, con odds ratio que varían entre 11,4 y 13,5. En estos hermanos la prevalencia de TDAH oscila entre el 26 y el 45,2%. Los hermanos con TDAH y aquellos sin TDAH están en mayor riesgo de sufrir otros trastornos, de los que el más frecuente es el trastorno de oposición desafiante (TOD). Conclusiones: Los hermanos de personas con TDAH tienen mayor riesgo de padecer el mismo trastorno. El riesgo de otro trastorno psiquiátrico aumenta marcadamente cuando el hermano también tiene TDAH; esto es aplicable especialmente al TOD, el trastorno por uso de sustancias y el trastorno bipolar.

ABSTRACT Introduction: Attention deficit and hyperactivity disorder (ADHD) occurs more frequently in first-degree relatives. It is believed that this risk is not specific to this disorder but also occurs with other psychopathologies. The study of siblings of ADHD probands is an interesting field since they share common environmental factors. Methods: This is a narrative literature review. A bibliographic search was performed on PubMed and PsychNet databases and topic-related publications were included without date of publication or study design limits. Results: Siblings of patients with ADHD have a higher likelihood of having this disorder when compared to controls, with odds ratios (OR) ranging between 11.4 and 13.5. Among these siblings, ADHD prevalence ranges between 26 and 45.2%. Siblings with ADHD and those without ADHD have an increased risk of having other disorders, the most frequent being oppositional defiant disorder (ODD). Conclusions: Siblings of people with ADHD have an increased risk of having the same disorder. The risk of having another psychiatric disorder markedly increases when the sibling also presents ADHD; this is especially true for ODD, substance use disorder and bipolar disorder.

Characteristics of sustained attention in stable patients withbipolar disorder and their first degree relatives / 中国心理卫生杂志

Objective:To explore the feature of impaired sustaind attention in the stable patients with bipolar disorder and their first degree relatives.Methods:Totally 76 patients with bipolar disorder meeting with, 83 first degree relatives of patients and 81 healthy controls, were employed and evaluated with continuous performance test (CPT).Results:In reaction time task (a simple performance), all of CPT parameters were higher in patients group than in the first degree relatives group and controlled group (Ps＜0.01), while all of CPT parameters in the first degree relatives group were similar to those in healthy controls (Ps＞0.05).In X task (a complex performance), the results of CPT in the first degree relatives group were between the patients and the normal controls, and the differences were statistically significant (Ps＜0.05).Conclusion:The sustained attention function may have a certain hereditary apparent in stable patients with bipolar disorder.

Differences in coping strategies in adult patients with bipolar disorder and their first-degree relatives in comparison to healthy controls / Diferenças entre as estratégias de coping em pacientes adultos com transtorno bipolar e seus familiares em comparação com controles saudáveis

Abstract Introduction: The objective of this study was to compare patients with bipolar disorder (BD), their first-degree relatives and a group of healthy controls in terms of use of adaptive and maladaptive coping strategies, exploring differences between specific types of strategies and their correlations with clinical variables. Methods: This was a cross-sectional study enrolling 36 euthymic patients with BD, 39 of their first-degree relatives and 44 controls. Coping strategies were assessed using the Brief COPE scale. Results: Significant differences were detected in the use of adaptive and maladaptive strategies by patients, their first-degree relatives and controls. Patients used adaptive strategies less often than the patients' relatives (p<0.001) and controls (p = 0.003). There was no significant difference between first-degree relatives and controls (p=0.707). In contrast, patients (p<0.001) and their relatives (p=0.004) both exhibited higher scores for maladaptive coping than controls. There was no significant difference regarding the use of maladaptive strategies between patients and their relatives (p=0.517). Conclusions: First-degree relatives were at an intermediate level between patients with BD and controls regarding the use of coping skills. This finding supports the development of psychosocial interventions to encourage use of adaptive strategies rather than maladaptive strategies in this population.

Resumo Introdução: O objetivo deste estudo foi comparar os pacientes com transtorno bipolar (TB), seus familiares de primeiro grau e um grupo de controles saudáveis em termos de uso de estratégias adaptativas e não adaptativas, explorando diferenças entre tipos específicos de estratégias e suas correlações com variáveis clínicas. Métodos: Estudo transversal, envolvendo 36 pacientes com TB eutímicos, 39 familiares de primeiro grau e 44 controles. As estratégias de enfrentamento foram avaliadas usando a escala Brief COPE. Resultados: Foram detectadas diferenças significativas no uso de estratégias adaptativas e não adaptativas por pacientes, seus familiares e controles. Os pacientes usaram estratégias adaptativas com menos frequência do que os familiares (p<0,001) e controles (p=0,003). Não houve diferença significativa entre familiares dos pacientes e controles (p=0,707). Por outro lado, os pacientes (p<0,001) e seus familiares (p=0,004) exibiram pontuações mais elevadas para coping não adaptativo em relação aos controles. Não houve diferença significativa quando os pacientes foram comparados com seus familiares (p=0,517). Conclusões: Familiares de primeiro grau estavam em um nível intermediário entre pacientes com TB e controles no que diz respeito ao uso de habilidades de enfrentamento. Esta descoberta apoia o desenvolvimento de intervenções psicossociais para incentivar o uso de estratégias adaptativas em vez de estratégias inadequadas nessa população.

Comparison of Cognitive Controls in Patients with Bipolar I Disorder and Their Unaffected First-Degree Relatives

OBJECTIVES: This study intended to identify the deficits of cognitive control among patients with bipolar I disorder and their first-degree relatives, and identify the possibility of cognitive control as an endophenotype of bipolar disorder. METHODS: The study included three groups: euthymic states patients with bipolar I disorder (n = 55), unaffected first-degree relatives of probands with bipolar I disorder (n = 30), and a healthy control group (n = 51), that was matched on age, sex, and years of education. The AX version of the continuous performance test (CPT) was used to examine cognitive control. Error rate, correct response times of each subsets (AX, BX, AY, BY), and d' as an indication of accuracy sensitivity index were calculated. Psychopathology, intelligence, and psychomotor speed were also assessed. RESULTS: Patients with bipolar I disorder showed significantly worse error rates in the AX (p = 0.01) and BX (p = 0.02) subsets and d' (p = 0.05) than the others. They also showed more delayed correct response times than the healthy control group and first-degree relatives in all subsets (p < 0.01). But first-degree relatives showed neither high error rates nor delayed correct response times than healthy control group. CONCLUSIONS: These findings suggest that cognitive control is impaired in bipolar I disorder but less likely to be an endophynotype of bipolar I disorder.

The anxious traits of the first-degree relatives and its influence on anxiety emotion of children with Tic disorders / 中华行为医学与脑科学杂志

Objective To explore the effects of first-degree relatives' anxious traits on the anxious emotion in children with Tic disorders ( TD) . Methods A total of 31 children with TD and 32 normal chil-dren were assessed by The Screen for Child Anxiety Related Emotional Disorders ( SCARED) ,and their first-degree relatives were assessed by State-Trait Anxiety Inventory ( STAI) . The differences of first-degree rela-tives' personality traits between two groups were compared,and the effects of these personality traits on chil-dren's anxious emotion were further analyzed. Results Compared with the control group(36. 66±8. 24),the first-degree relatives of children with TD had higher scores in trait anxiety (40. 10±8. 24,P<0. 05),but there was no significant difference in state anxiety between TD group and control group((35. 00±9. 09) vs (40. 90 ±10. 21),P>0. 05). The school phobia in children with TD was positively correlated with the education lev-els of their mothers(r=0. 407,P<0. 05). Conclusion The first-degree relatives of children with TD are more anxious emotion than normal children. Children with TD are more likely to have school phobia if their mothers have better education.

Cognitive functions in the first degree relatives of patients with schizophrenia in China:a meta-analysis / 中华行为医学与脑科学杂志

Objective To investigate the cognitive functions in first-degree relatives of patients with schizophrenia by meta-analysis. Methods Collect case-control studies of cognitive function in first-degree relatives of patients with schizophrenia,then extract data and assess the risk of bias of included studies,and use RevMan 5.3 to perform meta-analysis. Results A total of 27 studies involving 1708 people were includ-ed. Trail Marking A test(MD=3.59,P<0.01) and B test (MD=12.71,P=0.02),Stroop Color test((MD=-7.22,P<0.01),Stroop Color-Word test(MD=-7.25,P<0.01),Digit Symbol Coding test(MD=-7.29,P<0.01),Digit Span test(MD=-1.17,P<0.01),Hopkins Verbal Leaning test-Revised(MD=-4.58,P<0.01), Verbal Fluency test(MD=-2.92,P<0.01),Hanoi Tower(MD=-5.38,P<0.01),the number of corrected of WCST(MD=-3.10,P<0.01),number of completed categories of WCST (MD=-0.74,P<0.01),Persevera-tive Errors of WCST (MD=4.82,P<0.01) and Nonperseverative Errors of WCST (MD=8.00,P<0.01) scores between the first-degree relatives groups(FDR)and health control groups (HC)showed significant differences. Conclusion Cognitive impairment appears in the first-degree relatives populations of patients with schizophrenia,including the attention,verbal learning,working memory,and executive function.

BOLD-fMRI study on the basic activity of the brain in major disorder depression and their first-degree relatives / 实用放射学杂志

Objective To study the characteristics and differences of the amplitude of low-frequency fluctuation (ALFF) and the fractional ALFF (fALFF) of the major disorder depression (MDD) and their first-degree relatives in the resting state by functional magnetic resonance imaging (fMRI),to understand the early brain function in patients with MDD.Methods 3.0T fMRI in the resting state was performed in 10 patients with MDD (the depression group),10 first-degree relatives of MDD (the first-degree relatives group) and 10 healthy volunteers (the control group).A statistics analysis of ALFF and fALFF were performed subsequently.Results The ALFF and fALFF values measured in left cerebellum, left precuneus and left medial prefrontal cortex of MDD group were significantly lower than those of the first-degree relatives group (P<0.05).The ALFF values measured in right posterior cingulate cortex and right superior parietal lobule of MDD group were significantly lower than those of the first-degree relatives group (P<0.05).The ALFF and fALFF values measured in left cerebellum, left precuneus and left superior parietal lobule of MDD group were significantly lower than those of the control group (P<0.05).The ALFF values measured in right cingulate cortex and medial prefrontal cortex of MDD group were significantly lower than those of the control group (P<0.05).There was no significance difference found in ALFF values between the first-degree relatives group and the control group,the fALFF values measured in left superior parietallobule of the first-degree relatives group were significantly lower than those of the control group (P<0.05).Conclusion As the widespread ALFF, fALFF abnormalities of brain in MDD and first-degree relatives of MDD,a hypothesis can be get that these abnormal brain region may be associated with cognitive network disorders and emotional distress in MDD.

Comparative study of neurological soft signs in remittent schizophrenia and non-psychotic first-degree relatives / 中国神经精神疾病杂志

Objective To examine the difference of neurological soft signs (NSS) among the remittent schizophrenia patients,first-degree non-psychotic relatives of schizophrenia patients and healthy controls.Methods The Cambridge Neurological Inventory (CNI) (the Chinese version) was administered to 86 remittent schizophrenia patients (patient group),86 first-degree non-psychotic relatives of schizophrenia patients (relative group) and 86 healthy controls (control group).Results Compared with relative group,NSS total-score,the subscore of motor coordination and sensory integration were significantly higher in patient group (P＜0.01).Compared with control group,NSS total-score,the subscore of motor coordination and sensory integration were significantly higher in patient group (P＜0.01).Compared with control group,NSS total-score and the subscore of motor coordination were significantly higher in relative group (P＜0.01).Conclusions The levels of NSS in remittent schizophrenia patients and their first-degree non-psychotic relatives are higher than normal control,and the patients have more NSS than their relatives.The motor coordination nay be a potential endophenotype for schizophrenia.

Comparison of Cognitive Control Deficits in Patients with Schizophrenia and Their Unaffected First-Degree Relatives / 신경정신의학

OBJECTIVES: This study aimed to identify the differences in the profiles of cognitive control deficits among schizophrenic patients and endophenotypes. METHODS: The study examined three groups: remitted patients with schizophrenia (n=54), unaffected first-degree relatives of the probands with schizophrenia (n=36), and a healthy control group (n=51), which were all matched for age, sex, and years of education. The AX version of the continuous performance test was used to examine cognitive control. The error rate, correct response times of each subset (AX, BX, AY, BY), and d′ as an indication of the accuracy sensitivity index were calculated. The psychopathology, intelligence, and psychomotor speed were also assessed. RESULTS: Patients with schizophrenia showed significantly poorer error rates and d′ in the AX and BX subsets than the others. They showed more delayed correct response times than the healthy control group in all subsets. The first-degree relatives also showed more delayed correct response times in the BX and AY subsets than the healthy control group, but were similar to the patients. CONCLUSION: These findings suggest that cognitive control is impaired in schizophrenia and endophynotypes possibly share this delayed information processing from the higher loading states of cognitive control.
