Psychiatric disorders in patients with hepatocellular carcinoma: A large US cohort of commercially insured individuals

BACKGROUND/AIMS

Patients with hepatocellular cancer (HCC) are vulnerable to psychological distress given a new cancer diagnosis superimposed on pre-existing chronic liver disease. We aimed to characterise the psychiatric burden in HCC, risk factors for incident diagnosis and treatment patterns over time.

METHODS

Using IQVIA PharMetrics® Plus for Academics-a nationally representative claims database of the commercially insured US population-we identified psychiatric diagnoses and treatment among patients with newly diagnosed HCC. Multivariable logistic regression modelling identified factors associated with psychiatric diagnosis and treatment.

RESULTS

Of 11,609 patients with HCC, 2166 (18.6%) had a psychiatric diagnosis after cancer diagnosis with depression (58.3%) and anxiety (53.0%) being most common. Women (aOR 1.33, 95% CI [1.19-1.49]), pre-existing psychiatric diagnoses (aOR 9.12 [8.08-10.3]) and HCC treatment type (transplant: aOR 2.15 [1.66-2.77]; locoregional therapies: aOR 1.74 [1.52-1.99]; hospice: aOR 2.43 [1.79-3.29]) were significantly associated with psychiatric diagnosis. Female sex, ascites, higher comorbidity and treatment type were associated with incident psychiatric diagnosis. Pharmacotherapy was used in 1392 (64.3%) patients with a psychiatric diagnosis, with antidepressants (46.2%) and anxiolytics (32.8%) being most common. Psychiatric diagnoses increased from 14.8% in 2006-2009 to 21.1% in 2018-2021 (p < 0.001). In almost 20% of patients with pre-existing psychiatric conditions, therapy was discontinued after HCC diagnosis.

CONCLUSIONS

Nearly 2 of 10 patients with HCC were diagnosed with a psychiatric condition after cancer diagnosis with unique sociodemographic and clinical risk factors identified. This highlights a risk for increased psychological burden in need of early evaluation and treatment among patients with newly diagnosed HCC.

Enhancing the quality of life for physical therapists: insights from a cross-sectional study

Background

Physical Therapy profession is known for its demanding physical requirements. This increases the risk of attrition and work-related accidents and disorders that affect physical therapists' quality of life and work performance. This study aimed to evaluate the effect of physical activity level and other contributing factors on quality of life of physical therapists.

Methods

A cross-sectional study was conducted among practicing physical therapists (n = 258). The International Physical Activity Questionnaires-Short Form was used to measure physical activity levels and the World Health Organization Quality of Life Questionnaire short form was used to measure the quality of life among physical therapists. Data was collected through a self-administered online survey using Microsoft Forms.

Results

The eligible participants were 258 out of 297. The highest percentage of physical therapists had a moderate physical activity level (45.35%) and the median for overall quality of life score was 63.27(52.73-73.59). There was a significant positive correlation between physical activity and age with overall quality of life score (rs = 0.41, p < 0.001; rs = 0.13, p < 0.036) respectively and a significant negative correlation between body mass index and overall quality of life score (rs = -0.13, p < 0.04).

Conclusion

The results obtained revealed that physical therapists mostly have moderate physical activity level and relatively good perceived quality of Life. Furthermore, our study identified significant correlations between physical activity, age, body mass index, and the overall quality of life among practicing physical therapists.

Prevalence of personality disorders in adults with binge eating disorder-A systematic review and Bayesian meta-analysis

Binge eating disorder (BED) is a complex mental health problem entailing high risk for obesity, overweight, and other psychiatric disorders. However, there is still unclear evidence of the prevalence of personality disorders (PDs) in BED patients. We conducted a systematic review and a Bayesian meta-analysis for studies examining the prevalence of any PD in adult BED patients. Data sources included PubMed, Cochrane library, EBSCO, PsycINFO, and Science Direct. A Bayesian meta-analysis was conducted to estimate effect sizes for the prevalence of any PD in BED patients. Twenty eligible articles were examined with a total of 2945 BED patients. Borderline personality disorder and "Cluster C" PD, particularly obsessive-compulsive and avoidant PD, were the most frequent PD found in BED patients. BED diagnosis was associated with 28% probability of a comorbid diagnosis of any PD (0.279, 95%CrI: [0.22, 0.34]), with high levels of between-study heterogeneity (τ = 0.61, 95% CrI [0.40, 0.90]). Sensitivity analysis suggested effect sizes ranging from 0.27 to 0.28. The high comorbidity of PDs in BED patients draws attention to the potential complexity of BED clinical presentations, including those that might also be comorbid with obesity. Clinical practice should address this complexity to improve care for BED and obesity patients.

Inflammatory markers in outpatients with schizophrenia diagnosis in regular use of clozapine: a cross-sectional study

It is known that inflammation worsen the course of schizophrenia and induce high clozapine serum levels. However, no study evaluated this change in function of clozapine daily dose in schizophrenia. We assessed the correlation between inflammation and severity symptoms in patients with schizophrenia that take and do not take clozapine. We also assessed the correlation between clozapine daily dose and inflammatory markers to patients who take this drug. Patients were recruited from Schizophrenia Ambulatory and Psychosocial Care Center of Clinical Hospital of Porto Alegre and from an association of relatives of patients with schizophrenia. Exam results, and other important clinical exam were assessed in patients record or patients were asked to show their exam in the case of outpatients. We included 104 patients, 90 clozapine users and 14 non-clozapine users. We calculate the systemic inflammatory markers [neutrophil-lymphocyte ratio (NLR), systemic immune inflammation index (SII), and the psychopathology severity by the Brief Psychiatric Rating Scaled anchored (BPRS-a)]. These variables were compared between clozapine users and non-clozapine users. It was used mean/median test according to data distributing, with study factor (SII, MLR, and PLR), the clinical outcome: severity of symptomatology (BPRS score), and clozapine daily dose as adjustment factor. Clozapine users exhibited a significantly higher neutrophil count (mean ± SD: 5.03 ± 2.07) compared to non-clozapine users (mean ± SD: 3.48 ± 1.27; p = 0.031). After controlling for comorbidity, other parameters also showed significant differences. These findings are consistent with previous studies that have demonstrated an inflammatory response following the administration of clozapine.

Towards an adiposity-related disease framework for the diagnosis and management of obesities

Obesity is a complex disease that relapses frequently and associates with multiple complications that comprise a worldwide health priority because of its rising prevalence and association with numerous complications, including metabolic disorders, mechanic pathologies, and cancer, among others. Noteworthy, excess adiposity is accompanied by chronic inflammation, oxidative stress, insulin resistance, and subsequent organ dysfunction. This dysfunctional adipose tissue is initially stored in the visceral depot, overflowing subsequently to produce lipotoxicity in ectopic depots like liver, heart, muscle, and pancreas, among others. People living with obesity need a diagnostic approach that considers an exhaustive pathophysiology and complications assessment. Thus, it is essential to warrant a holistic diagnosis and management that guarantees an adequate health status, and quality of life. The present review summarizes the different complications associated with obesity, at the same time, we aim to fostering a novel framework that enhances a patient-centered approach to obesity management in the precision medicine era.

Advances in Anti-obesity Pharmacotherapy: Current Treatments, Emerging Therapies, and Challenges

Obesity is a major public health concern linked to health risks such as hypertension, hyperlipidemia, type 2 diabetes mellitus (T2DM), stroke, metabolic syndrome, asthma, and cancer. It is among the leading causes of morbidity and mortality worldwide caused by an unhealthy diet and lack of physical activity, but genetic or hormonal factors may also contribute. Over a third of adults in the United States are obese. Pharmacological agents have been designed to reduce weight gain caused by excessive calorie intake and low physical activity. They work by inhibiting the absorption of dietary fat or stimulating the secretion of satiety hormones. These drugs include lipase inhibitors and glucagon-like peptide 1 (GLP-1) receptor agonists. However, the current weight-loss strategies do not effectively treat genetic-related diseases, such as generalized lipodystrophy, Bardet-Biedl syndrome, and proopiomelanocortin (POMC) deficiency. Emerging therapies for these gene mutations have been developed targeting leptin and melanocortin-4 receptors (MC4Rs), restoring the normal function of leptin or melanocortin-4 receptors regulating energy balance and appetite. Leptin analogs and MC4R agonists are novel therapies that target genetic or hormonal causes of obesity. This article provides a comprehensive review of anti-obesity medications (AOMs). In this review, we discuss the clinical trials, efficacy, United States FDA-approved indication, contraindications, and serious side effects of different classes of drugs, including lipase inhibitors, GLP-1 agonists, leptin analogs, and MC4R agonists.

Physical activity, sleep, and mental health during the COVID-19 pandemic: A one-year longitudinal study of Spanish university students

The objective of this longitudinal study was to analyze changes in physical activity, sedentary time, sleep, anxiety, mood, and perceived health as a result of COVID-19 pandemic in a cohort of Spanish university students, both during the home confinement and one year after. Additionally, we analyzed the associations between physical activity, sedentary time, and other measured parameters. Data were collected through two online questionnaires that included the International Physical Activity Questionnaire-Short Form, the Pittsburgh Sleep Quality Index, and self-reported anxiety, mood, and perceived health levels before, during and one year after home confinement. Participants reported decreased physical activity, increased sedentary time, and deterioration in sleep quality and perceived health during confinement. Most parameters had improved one year later; however, the participants still reported less physical activity, more sedentary time, and deterioration in sleep quality and perceived health compared to before confinement. Men reported greater reduction of physical activity during home confinement than women. In contrast, women reported reduced physical activity one year after confinement, whereas men reported increased activity. Participants reported higher anxiety and worse mood both during and one year post-confinement compared to pre-confinement, with women reporting higher levels of anxiety than men. Sports science students were closer to regaining pre-pandemic levels of physical activity one year post-confinement than students in other disciplines. Sleep, anxiety, and mood were worse among students with obesity compared to students in other BMI categories. Overall, increased physical activity and decreased sedentary time were associated with less anxiety and better sleep, mood, and perceived health during and one year post-confinement. In conclusion, our results demonstrate that physical activity, sedentary behavior, sleep, anxiety, mood, and perceived health were disrupted one year after home confinement. Higher levels of physical activity and lower sedentary time were associated with preserved sleep and mental health during the pandemic.

Executive Attentional Dyscontrol as a Core Cognitive and Behavioral Feature of Individuals with Obesity and Cardiovascular Disease: A Cross-Sectional Investigation

Executive attention as a frontal domain ability that is effective in potentially blocking distracting information, reconciling conflicts among simultaneous attentional demands, and regulating impulsive behavior may be impaired in individuals with obesity and cardiovascular disease (CVD). This study aimed (i) to explore the presence of selected cognitive (global cognitive impairment, sensitivity to interference, and attention) and psychological (quality of life, depression, anxiety, and impulsivity) dimensions and (ii) to examine the interactive relationship between attentional dyscontrol-both as a psychological and as a cognitive measure-and the above-mentioned variables in a sample of patients with CVD attending a cardiac rehabilitation program across different body mass index (BMI) levels. Clinical information of 104 patients with CVD was retrospectively collected. Participants were classified into three groups according to their BMI as follows: normal weight (NW = 30), overweight (OW = 19), and obese (OB = 55). Individuals with CVD and a higher BMI showed problems in controlling executive attention-through both neuropsychological and behavioral measures. Specifically, OB patients demonstrated reduced sensitivity to cognitive interference, lower capabilities in divided attention during visual-tracking tasks, and greater impulsivity compared to NW patients. This behavioral characteristic was also found to be correlated with higher levels of anxiety and depression and a lower quality of life. Implications for cognitive rehabilitation were discussed to offer directions for better management of patients with CVD and obesity.

[Physical growth and dietary characteristics of children with attention deficit hyperactivity disorder: a cross-sectional study]

OBJECTIVES

To investigate the physical growth and dietary characteristics of children with attention deficit hyperactivity disorder (ADHD), and to analyze their relationship with core symptoms of ADHD.

METHODS

A total of 268 children who were newly diagnosed with ADHD in Children's Hospital of Nanjing Medical University from June to December 2020 were included in the ADHD group, and 102 healthy children who underwent physical examination during the same period were selected as the control group. Physical evaluations and dietary surveys were conducted for both groups. ADHD diagnosis and scoring were performed according to the Diagnostic and Statistical Manual of Mental Disorders (5th edition). Factor analysis, Spearman correlation analysis, and mediation analysis were used to study the relationship between core symptoms of ADHD, dietary patterns, and physical growth.

RESULTS

The rate of overweight/obesity in the ADHD group was significantly higher than that in the control group (35.8% vs 21.6%, P<0.05). Three dietary patterns were extracted from the food frequency questionnaire: vegetarian dietary pattern, traditional dietary pattern, and snack/fast food pattern. The factor score for the snack/fast food pattern in the ADHD group was higher than that in the control group (P<0.05). There was a significant positive correlation between ADHD symptom scores, snack/fast food pattern factor scores, and body fat percentage (P<0.05). The mediation analysis showed that the snack/fast food pattern played a partial mediating role in the relationship between ADHD symptom scores and body fat percentage, with a mediation proportion of 26.66%.

CONCLUSIONS

The rate of overweight/obesity in children with ADHD is higher than that in non-ADHD children. Core symptoms of ADHD are related to dietary patterns and physical growth, with the snack/fast food pattern playing a partial mediating role in the relationship between core symptoms of ADHD and physical growth.

Abnormal blood lipid and electrocardiogram characteristics in common mental disorders

BACKGROUND

At present, there is not enough evidence to prove the relationship between blood lipid and electrocardiogram (ECG) abnormalities in common mental disorders (CMD). This study aimed to explore the relationship between them, to detect and prevent arrhythmia or sudden death.

METHODS

We collected 272 CMD patients (maintained a fixed drug dose pattern for 1 year or more), including 95 schizophrenias (SC), 90 bipolar disorders (BD) and 87 major depressive disorders (MDD), and 78 healthy controls (HC) from the Third People's Hospital of Foshan, China. We analyzed and compared their blood lipid and ECG indicators, to clarify the relationship between them.

RESULTS

350 participants were included. There were no significant differences in age, gender, total cholesterol (TC), low density lipoprotein (LDL) and QTc (p > 0.05) among subjects. And there were significant differences in body mass index (BMI), triglyceride (TG), high density lipoprotein (HDL), heart rate, PR interval and QRS width (p < 0.05). Person correlation analysis showed that QRS width was positively correlated with BMI and TG. And negatively correlated with HDL. Meanwhile, QTc was positively correlated with BMI. Multiple linear regional analysis further proved that TG (B = 3.849, p = 0.007) and LDL (B = 11.764, p = 0.018) were the risk factors, and HDL (B = -9.935, p = 0.025) was the protective factor for QRS width increase.

CONCLUSION

Long term medication of CMD patients should strengthen weight management, and conduct regular blood lipid and ECG examinations to achieve early detection and intervention in order to promote their health.

The Preventive Mechanisms of Bioactive Food Compounds against Obesity-Induced Inflammation

Dietary patterns are promising strategies for preventing and treating obesity and its coexisting inflammatory processes. Bioactive food compounds have received considerable attention due to their actions against obesity-induced inflammation, with limited harmful side effects. They are perceived as food ingredients or dietary supplements other than those necessary to meet basic human nutritional needs and are responsible for positive changes in the state of health. These include polyphenols, unsaturated fatty acids, and probiotics. Although the exact mechanisms of bioactive food compounds' action are still poorly understood, studies have indicated that they involve the modulation of the secretion of proinflammatory cytokines, adipokines, and hormones; regulate gene expression in adipose tissue; and modify the signaling pathways responsible for the inflammatory response. Targeting the consumption and/or supplementation of foods with anti-inflammatory potential may represent a new approach to obesity-induced inflammation treatment. Nevertheless, more studies are needed to evaluate strategies for bioactive food compound intake, especially times and doses. Moreover, worldwide education about the advantages of bioactive food compound consumption is warranted to limit the consequences of unhealthy dietary patterns. This work presents a review and synthesis of recent data on the preventive mechanisms of bioactive food compounds in the context of obesity-induced inflammation.

Executive function, behavioral problems, and insulin resistance in adolescents with obesity

OBJECTIVES

In this study, we examined executive function (EF) abilities, behavioral and emotional (BE) issues, and overall quality of life (QoL) of adolescents with obesity and compared them with a control group and also aimed to investigate whether the presence of insulin resistance (IR) is associated with these problems.

METHODS

This cross-sectional study included a sample of 50 adolescents aged 11-18 years with obesity and age- and gender-matched 50 normal weight adolescents who had attended and were treated at the pediatric outpatient clinic. Sociodemographic data were collected through personal interviews with the adolescents and their parents. Measurements of the height and weight, fasting blood glucose, and insulin levels of all adolescents were assessed. In addition, the participants and their parents completed the Kiddo-KINDL, the Strengths and Difficulties Questionnaire, and the Behavior Rating Inventory Scale from Executive Function.

RESULTS

Of the 50 adolescents with obesity, 27 (54.0 %) were girls, and 23 (46.0 %) were boys, with a mean age of 14.06 ± 1.83 years. Adolescents with obesity have more EF deficiencies, BE difficulties, more problems in peer relationships and lower QoL scores than those without obesity. The QoL was worse in girls, adolescents with obesity, and those with IR. Adolescents with obesity and those with and without IR did not differ about EF deficiencies and BE problems.

CONCLUSIONS

Addressing these EF deficits and BE problems in interventions for adolescents who have difficulty adapting to lifestyle changes, an essential part of obesity treatment in clinical practice, may contribute to treatment success.

Shared genetics between classes of obesity and psychiatric disorders: A large-scale genome-wide cross-trait analysis

AIMS

Epidemiological studies demonstrate an association between classes of obesity and psychiatric disorders, although little is known about shared genetics and causality of association. Thus, we aimed to investigate shared genetics and causal link between different classes of obesity and psychiatric disorders.

METHODS

We used genome-wide association study (GWAS) summary data range from 9725 to 500,199 sample sizes of European descent, conducted a large-scale genome-wide cross-trait association study to investigate genetic overlap between the classes of obesity and anorexia nervosa, attention-deficit/hyperactivity disorder, autism spectrum disorder, bipolar disorder, major depressive disorder, obsessive-compulsive disorder, schizophrenia, anxiety disorders and Tourette syndrome. We conducted transcriptome-wide association study analysis (TWAS) to identified variants regulated gene expression in those related disorders. Finally, pathway enrichment analysis to identified major pathways.

RESULTS

In the combined analysis, we replicated 211 previously reported loci and discovered 58 novel independent loci that were associated with all three classes of obesity and related psychiatric disorders. Functional analysis revealed that the identified variants regulated gene expression in major tissues belonging to exocrine/endocrine, digestive, circulatory, adipose, digestive, respiratory, and nervous systems, such as DCC, NEGR1, INO80E. Mendelian randomization analyses suggested that there may be a two-way or one-way causal relationship between obesity and psychiatric disorders.

CONCLUSION

This large-scale genome-wide cross-trait analysis identified shared genetics and potential causal links between classes of obesity and psychiatric disorders (attention deficit hyperactivity disorder, autism spectrum disorder, anorexia nervosa, major depressive disorder, schizophrenia, and obsessive-compulsive disorder). Such shared genetics suggests potential new biological functions in common among them.

Oxytocin and cardiometabolic interoception: Knowing oneself affects ingestive and social behaviors

Maintaining homeostasis while navigating one's environment involves accurately assessing and interacting with external stimuli while remaining consciously in tune with internal signals such as hunger and thirst. Both atypical social interactions and unhealthy eating patterns emerge as a result of dysregulation in factors that mediate the prioritization and attention to salient stimuli. Oxytocin is an evolutionarily conserved peptide that regulates attention to exteroceptive and interoceptive stimuli in a social environment by functioning in the brain as a modulatory neuropeptide to control social behavior, but also in the periphery as a hormone acting at oxytocin receptors (Oxtr) expressed in the heart, gut, and peripheral ganglia. Specialized sensory afferent nerve endings of Oxtr-expressing nodose ganglia cells transmit cardiometabolic signals via the Vagus nerve to integrative regions in the brain that also express Oxtr(s). These brain regions are influenced by vagal sensory pathways and coordinate with external events such as those demanding attention to social stimuli, thus the sensations related to cardiometabolic function and social interactions are influenced by oxytocin signaling. This review investigates the literature supporting the idea that oxytocin mediates the interoception of cardiovascular and gastrointestinal systems, and that the modulation of this awareness likewise influences social cognition. These concepts are then considered in relation to Autism Spectrum Disorder, exploring how atypical social behavior is comorbid with cardiometabolic dysfunction.

Prevalence and associated factors of obesity and overweight in Chinese patients with bipolar disorder

OBJECT

Despite abundant literature demonstrating a high prevalence of obesity and overweight in people with bipolar disorder (BD), little is known about this topic in China. Therefore, we assessed the prevalence and associated factors of obesity and overweight among inpatients with BD in our hospital, one of the largest public psychiatric hospitals in China.

METHODS

In this retrospective, cross-sectional study, 1,169 inpatients ≥18 years with BD during 2019 were included. Obesity was defined as having a BMI ≥25 kg/m², and overweight was defined as having a BMI from 23 kg/m² to <25 kg/m². Binary logistic regression analysis was performed to identify factors associated with obesity and overweight.

RESULTS

The prevalence of obesity and overweight was 21.0% and 32.2% in patients with BD, respectively. Compared to patients with overweight and normal weight, patients with obesity were older, had a longer duration of BD and a longer length of hospital stay, had a higher prevalence of diabetes and hypertension, and had a higher level of all metabolic indices, except for HDL cholesterol. Binary logistic regression analysis showed that duration of BD, uric acid, alanine aminotransferase (ALT), triglyceride, and LDL cholesterol were significantly associated with obesity, and male sex and uric acid level were significantly associated with overweight (p < 0.05).

CONCLUSIONS

Obesity and overweight were fairly prevalent in Chinese BD patients, and several factors were related to obesity and overweight. The results of the present study call for the need to implement early screening, prevention and interventions for obesity and overweight in patients with BD in China.
