Longitudinal Multi-omics Reveals Subset-Specific Mechanisms Underlying Irritable Bowel Syndrome.

The gut microbiome has been implicated in multiple human chronic gastrointestinal (GI) disorders. Determining its mechanistic role in disease has been difficult due to apparent disconnects between animal and human studies and lack of an integrated multi-omics view of disease-specific physiological changes. We integrated longitudinal multi-omics data from the gut microbiome, metabolome, host epigenome, and transcriptome in the context of irritable bowel syndrome (IBS) host physiology. We identified IBS subtype-specific and symptom-related variation in microbial composition and function. A subset of identified changes in microbial metabolites correspond to host physiological mechanisms that are relevant to IBS. By integrating multiple data layers, we identified purine metabolism as a novel host-microbial metabolic pathway in IBS with translational potential. Our study highlights the importance of longitudinal sampling and integrating complementary multi-omics data to identify functional mechanisms that can serve as therapeutic targets in a comprehensive treatment strategy for chronic GI diseases. VIDEO ABSTRACT.

Genome-wide transcriptomic and biochemical profiling of major depressive disorder: Unravelling association with susceptibility, severity, and antidepressant response.

Identifying biomarkers for diagnosing Major Depressive Disorder (MDD), assessing its severity, and guiding treatment is crucial. We conducted whole genome transcriptomic study in North Indian population, and analyzed biochemical parameters. Our longitudinal study investigated gene-expression profiles from 72 drug-free MDD patients and 50 healthy controls(HCs) at baseline and 24 patients after 12-weeks of treatment. Gene expression analyses identified differentially expressed genes(DEGs) associated with MDD susceptibility, symptom severity and treatment response, independently validated by qPCR. Hierarchical clustering revealed distinct expression patterns between MDD and HCs, also between mild and severe cases. Enrichment analyses of significant DEGs revealed inflammatory, apoptosis, and immune-related pathways in MDD susceptibility, severity, and treatment response. Simultaneously, we assessed thirty biochemical parameters in the same cohort, showed significant differences between MDD and HCs in 13 parameters with monocytes, eosinophils, creatinine, SGPT, and total protein remained independent predictors of MDD in a multivariate-regression model. Our study supports the role of altered immune/inflammatory signaling in MDD pathophysiology, offering clinically relevant biochemical parameters and insights into transcriptomic gene regulation in MDD pathogenesis and treatment response.

Ambient pollen exposure and pollen allergy symptom severity in the EPOCHAL study.

BACKGROUND: Ambient pollen exposure causes nasal, ocular, and pulmonary symptoms in allergic individuals, but the shape of the exposure-response association is not well characterized. We evaluated this association and determined (1) whether symptom severity differs between subpopulations; (2) how the association changes over the course of the pollen season; and (3) which pollen exposure time lags affect symptoms. METHODS: Adult study participants (n = 396) repeatedly scored severity of nasal, ocular, and pulmonary allergic symptoms, resulting in three composite symptom scores. We calculated hourly individually relevant pollen exposure to seven allergenic plants (alder, ash, birch, hazel, grasses, mugwort, and ragweed) considering personal sensitization and exposure time lags of up to 96 h. We fitted generalized additive mixed models, with a random personal intercept, adjusting for weather and air pollution as potential time-varying confounders. RESULTS: We identified a clear nonlinear positive association between pollen exposure and ocular and nasal symptom severity in the pollen allergy group: Symptom severity increased steeply with increasing exposure initially, but attenuated beyond approximately 80 pollen/m3. We found no evidence of an exposure threshold, below which no symptoms occur. While recent pollen exposure in the last approximately 5 h affected symptoms most, associations lingered for up to 60 h. Grass pollen exposure (compared to tree pollen) and younger age (18-30 years, as opposed to 30-65 years) were both associated with higher nasal and ocular symptom severity. CONCLUSIONS: The lack of a threshold and attenuated dose-response curve may have implications for pollen warning systems, which may be revised to include multiday pollen concentrations in the future.

Enlarged pituitary gland volume: a possible state rather than trait marker of psychotic disorders.

BACKGROUND: Enlarged pituitary gland volume could be a marker of psychotic disorders. However, previous studies report conflicting results. To better understand the role of the pituitary gland in psychosis, we examined a large transdiagnostic sample of individuals with psychotic disorders. METHODS: The study included 751 participants (174 with schizophrenia, 114 with schizoaffective disorder, 167 with psychotic bipolar disorder, and 296 healthy controls) across six sites in the Bipolar-Schizophrenia Network on Intermediate Phenotypes consortium. Structural magnetic resonance images were obtained, and pituitary gland volumes were measured using the MAGeT brain algorithm. Linear mixed models examined between-group differences with controls and among patient subgroups based on diagnosis, as well as how pituitary volumes were associated with symptom severity, cognitive function, antipsychotic dose, and illness duration. RESULTS: Mean pituitary gland volume did not significantly differ between patients and controls. No significant effect of diagnosis was observed. Larger pituitary gland volume was associated with greater symptom severity (F = 13.61, p = 0.0002), lower cognitive function (F = 4.76, p = 0.03), and higher antipsychotic dose (F = 5.20, p = 0.02). Illness duration was not significantly associated with pituitary gland volume. When all variables were considered, only symptom severity significantly predicted pituitary gland volume (F = 7.54, p = 0.006). CONCLUSIONS: Although pituitary volumes were not increased in psychotic disorders, larger size may be a marker associated with more severe symptoms in the progression of psychosis. This finding helps clarify previous inconsistent reports and highlights the need for further research into pituitary gland-related factors in individuals with psychosis.

Sleep disorders in a naturalistic cohort of Dutch psychiatric outpatients: prevalence rates and associations with psychopathology symptom severity and well-being.

Sleep problems are very common in individuals with a mental disorder. Given the abundant evidence indicating the negative impact of disturbed sleep on mental health outcome, insight into the prevalence of all types of sleep disorders in specific mental disorders and neurodevelopmental conditions is of practical importance. Therefore, we estimated the prevalence of six types of sleep disorders with the Holland Sleep Disorders Questionnaire in an overall mental health sample (n = 1082) and separately for different mental and neurodevelopmental conditions. Furthermore, associations between specific sleep disorders, psychopathology and well-being were studied. The impact of the total number of sleep disorders on these associations was examined. Overall, 46.2% of all participants scored above the cut-off for having a sleep disorder. Specifically, 26.8% scored on insomnia, 12.1% on sleep breathing disorders, 9.7% on hypersomnia, 13.7% on circadian rhythm sleep-wake disorders, 11.2% on parasomnia, and 17.9% on sleep-related movement disorders. Most sleep disorders were associated with greater severity of psychopathology and lower well-being. These associations got stronger with an increasing number of sleep disorders. Our study revealed higher suspected prevalence of most sleep disorders in a mental disorder sample compared to the general population. Moreover, the presence of sleep disorder(s) was strongly associated with symptom severity and reduced well-being. These findings extend the notion that early detection and treatment of sleep disorders in mental health populations is essential for psychiatric outcome.

Altered single-subject gray matter structural networks in social anxiety disorder.

Previous fMRI studies have reported more random brain functional graph configurations in social anxiety disorder (SAD). However, it is still unclear whether the same configurations would occur in gray matter (GM) graphs. Structural MRI was performed on 49 patients with SAD and on 51 age- and gender-matched healthy controls (HC). Single-subject GM networks were obtained based on the areal similarities of GM, and network topological properties were analyzed using graph theory. Group differences in each topological metric were compared, and the structure-function coupling was examined. These network measures were further correlated with the clinical characteristics in the SAD group. Compared with controls, the SAD patients demonstrated globally decreased clustering coefficient and characteristic path length. Altered topological properties were found in the fronto-limbic and sensory processing systems. Altered metrics were associated with the illness duration of SAD. Compared with the HC group, the SAD group exhibited significantly decreased structural-functional decoupling. Furthermore, structural-functional decoupling was negatively correlated with the symptom severity in SAD. These findings highlight less-optimized topological configuration of the brain structural networks in SAD, which may provide insights into the neural mechanisms underlying the excessive fear and avoidance of social interactions in SAD.

Associations between menopausal symptoms and cardiovascular disease in middle-aged Chinese women.

OBJECTIVE: This study aimed to examine the association between severity of menopausal symptoms and cardiovascular disease (CVD) risk among middle-aged Chinese women. METHODS: A cross-sectional study recruited 9679 women aged 40-70 years from three socioeconomic regions of China in 2018. Menopausal symptoms were assessed by the modified Kupperman Menopausal Index (KMI). The severity of individual symptoms was classified as none (0 points), mild (1 points) and moderate-to-severe symptoms (2-3 points), and overall menopausal symptoms were classified as none (<15 points), mild (15-24 points) or moderate-to-severe (≥25 points) according to the sum score of the KMI. Logistic regression models were used to examine associations of the severity of menopausal symptoms with CVD risk. RESULTS: A total of 5.6% of participants reported being diagnosed with CVD. Overall menopausal symptoms were more common in women aged 60-70 years than in women aged 40-59 years. After multiple adjustment, mild (odds ratio [OR] = 2.07, 95% confidence interval [CI]: 1.64-2.61) and moderate-to-severe (OR = 2.64, 95% CI: 1.92-3.63) overall menopausal symptoms were associated with increased risk of CVD compared with no symptoms. Significant positive associations between the severity of individual menopausal symptoms and CVD risk were observed for all 13 items. CONCLUSION: The severity of menopausal symptoms was positively associated with CVD risk in middle-aged Chinese women.

The effect of repeated concussions on clinical and neurocognitive symptom severity in different contact sports.

INTRODUCTION: The potential consequences of repeated concussions in sport are well documented. However, it remains unclear whether the cumulative impact of sports-related concussions differs between different contact sports. Therefore, the aim of the current study was to investigate the cumulative effects of sports-related concussions on clinical and neurocognitive health in different contact sports. MATERIALS AND METHODS: In a prospective multicenter study, we examined 507 (74 females) active professional athletes between 18 and 40 years of age from five different contact sports (soccer, handball, American football, basketball, and ice hockey). Data collection involved concussion history, clinical symptom evaluation, neurocognitive assessment, and the collection of other sports-related information. Composite scores were built for clinical symptoms (such as neck pain and balance disturbances) and for neurocognitive symptoms (such as memory and attention impairments). RESULTS: Athletes having suffered 3+ concussions in the past showed disproportionally higher clinical symptom severity than athletes with less than three concussions across all sports. The level of clinical symptom burden in athletes with 3+ concussions indicated mild impairment. The number of past concussions did not affect neurocognitive performance. DISCUSSION: Repeated sports-related concussions appear to have a cumulative impact on clinical-but not cognitive-symptom severity. Although clinical symptom burden in athletes with 3+ concussions in the past was not alarmingly high yet in our sample, increased caution should be advised at this point. Despite few exceptions, results are similar for different contact sports, suggesting a similar multidisciplinary concussion management across all types of sport.

Evaluation of the effects of the FODMAP diet and probiotics on irritable bowel syndrome (IBS) symptoms, quality of life and depression in women with IBS.

BACKGROUND: The present study aimed to evaluate the effects of fermented oligosaccharide, disaccharide, monosaccharide and polyols (FODMAP) diet therapy and probiotics on irritable bowel syndrome (IBS) symptoms, quality of life and depression in women diagnosed with IBS. METHODS: For the study, 52 female IBS patients between the ages of 20 and 55 were enrolled. Individuals were monitored for 6 weeks in two groups. A low-FODMAP diet was given to the first group and a low-FODMAP diet plus a probiotic supplement was given to the second group (Lactobacillus rhamnosus). Three-day food intake records were kept at the start of the study and continued up to its conclusion, with a weekly check-in in between. At the start and end of the trial, participants completed the Hospital Anxiety and Depression Scale, IBS Quality of Life Scale (IBS-QOL) and IBS Symptom Severity Score (IBS-SSS). The Bristol Stool Scale was also used by the subjects to record their daily stool densities. RESULTS: At the end of the study, it was determined that the daily intake of FODMAP (lactose [g] + oligosaccharides [g] + mannitol [g] + sorbitol [g]) decreased significantly in both groups (p < 0.05). At the end of the study, it was determined that the IBS-SSS, anxiety and depression scores of the individuals in both groups decreased significantly and their IBS-QOL scores increased significantly (p < 0.05). However, the difference between these values between the groups was not statistically significant (p > 0.05). CONCLUSIONS: A low-FODMAP diet has been demonstrated to benefit people by lessening the severity of their IBS symptoms and enhancing their quality of life. No evidence was found, however, to indicate that the FODMAP diet would be more beneficial on these metrics if additional probiotics were used. It should be emphasised that the reaction of probiotic strains may vary depending on the IBS subtype.

Are there any benefits for post-operative splinting after carpal tunnel release? A systematic review and meta-analysis.

BACKGROUND: There is a controversy on the effectiveness of post-operating splinting in patients with carpal tunnel release (CTR) surgery. This study aimed to systematically evaluate various outcomes regarding the effectiveness of post-operating splinting in CTR surgery. METHODS: Multiple databases, including PubMed, EMBASE, CINAHL, Web of Science, and Cochrane, were searched for terms related to carpal tunnel syndrome. A total of eight studies involving 596 patients were included in this meta-analysis. The quality of studies was evaluated, and their risk of bias was calculated using the methodological index for non-randomized studies (MINORS) and Cochrane's collaboration tool for assessing the risk of bias in randomized controlled trials. Data including the visual analogue scale (VAS), pinch strength, grip strength, two-point discrimination, symptom severity score (SSS), and functional status scale (FSS) were extracted. RESULTS: Our analysis showed no significant differences between the splinted and non-splinted groups based on the VAS, SSS, FSS, grip strength, pinch strength, and two-point discrimination. The calculated values of the standardized mean difference (SMD) or the weighted mean difference (WMD) and a 95% confidence interval (CI) for different variables were as follows: VAS [SMD = 0.004, 95% CI (-0.214, 0.222)], pinch strength [WMD = 1.061, 95% CI (-0.559, 2.681)], grip strength [SMD = 0.178, 95% CI (-0.014, 0.369)], SSS [WMD = 0.026, 95% CI (- 0.191, 0.242)], FSS [SMD = 0.089, 95% CI (-0.092, 0.269)], and the two-point discrimination [SMD = 0.557, 95% CI (-0.140, 1.253)]. CONCLUSIONS: Our findings revealed no statistically significant differences between the splinted and non-splinted groups in terms of the VAS, SSS, FSS, grip strength, pinch strength, and two-point discrimination. These results indicate that there is no substantial evidence supporting a significant advantage of post-operative splinting after CTR.

Relationship between severity of concussion's symptoms and functional performance in children.

INTRODUCTION: Concussion is a common brain injury that has significant effects on multiple functional domains in children. However, limited research exists on the relationship between concussion severity and functional performance in this population. This study aimed to examine the relationship between the severity of concussion symptoms and children's balance and functional performance. METHODS: This cross-sectional study recruited 23 children (9 males and 14 females; mean age 13.9 ± 2.2 years) with clinically diagnosed concussions from a tertiary balance center in 2016. Participants underwent clinical and functional evaluations by specialized physical therapists. Symptom severity was assessed using the Post-Concussion Symptom Scale (PCSS), while functional performance was measured using the Functional Gait Assessment (FGA). RESULTS: There was a trend suggesting a negative correlation between symptom severity (PCSS) and functional performance (FGA), indicating potentially better performance in individuals with milder symptoms. However, this trend was not significant (rs (21) = -.072, p = 0.744). Furthermore, no significant correlation was found between FGA scores and the severity of individual symptoms. CONCLUSION: The findings suggest that concussion symptom severity may not be directly related to functional performance in children. Therefore, it is crucial to incorporate functional performance measures alongside symptom assessment for comprehensive concussion management.

Children's emotional reactivity and negative affect predict future ADHD symptom severity beyond initial ADHD symptom severity.

Children with Attention-Deficit/Hyperactivity Disorder (ADHD) often experience significant emotion dysregulation. However, there is limited longitudinal data on associations between multiple aspects of emotion dysregulation and ADHD symptoms. Additionally, given substantial evidence that increased levels and variability of negative affect (NA) are identified in children with ADHD, it is important to examine the role of NA in this relationship. The present study used momentary and longitudinal data to examine the relation between two aspects of emotion dysregulation (emotional lability and emotional reactivity), the two ADHD symptom clusters separately (inattentive and hyperactive/impulsive), total ADHD symptom severity, and NA variability over a period of six months. Participants (N = 68) were parents of children aged 7-12 years old (M = 9.80, SD = 1.34) who completed baseline and 6-month follow-up reports of children's ADHD symptoms and emotion dysregulation as well as ecological momentary assessments (EMA) of their children's NA for one week. Results were threefold: (1) children's emotional reactivity predicted inattentive, hyperactive/impulsive, and total ADHD symptom severity above and beyond initial ADHD symptom severity, but emotional lability did not significantly predict severity of any ADHD symptom cluster; (2) NA variability predicted hyperactive/impulsive and total ADHD symptom severity, but not inattentive severity; and (3) initial ADHD symptom severity did not predict emotion dysregulation at follow-up. The current study provides novel insight regarding the longitudinal influence of specific aspects of emotion dysregulation and NA on ADHD symptom severity in children and suggests that targeting emotional reactivity could minimize ADHD symptom severity.

Does skin prick test response intensity predict symptom severity and efficacy of subcutaneous immunotherapy in allergic rhinitis?

OBJECTIVES: To investigate the effect of response intensity of allergen skin prick test (SPT) on symptom severity and long-term efficacy of dust mite subcutaneous immunotherapy (SCIT) in allergic rhinitis (AR). METHODS: AR Patients diagnosed with dust mite allergy and completed 3 years of SCIT were collected and classified into three groups: grade 2 (SPT of + +), grade 3 (SPT of + + +) and grade 4 (SPT of + + + +). Comparisons between groups were performed to examine the associations of SPT categories and symptom severity and the long-term efficacy of SCIT in AR. RESULTS: 181 AR patients were included. There was no significant difference in the baseline TNSS, SMS, RQLQ and VAS, and particularly to symptom severity grading among three SPT grade groups (P > 0.05). The moderate-severe AR was more likely to be smoking and accompany with asthma and had higher prevalence of sensitization to cockroach, mixed grass and tree pollen than mild AR (P < 0.05). Prevalence of sensitization to cockroach, mixed grass, ragweed and animal dander was increased in AR patients with asthma and allergic conjunctivitis (P < 0.05). Furthermore, after 3 years of SCIT, no statistical differences in TNSS, SMS, RQLQ, VAS and long-term efficacy were observed among the three SPT grade groups (P > 0.05). Similarly, long-term outcomes of patients with different SPT grades did not differ among different clinical characteristics and different efficacy determination criteria (P > 0.05). CONCLUSIONS: The SPT response intensity cannot be used as an objective evaluation index for symptom severity and the long-term efficacy of SCIT in AR patients.

Sino-nasal Outcome Test (SNOT22) score in adult population with no known sino-nasal disease.

PURPOSE: This cross-sectional study aimed to establish normative values for Sino-Nasal Outcome Test (SNOT-22) score in adult Indian population without known sino-nasal diseases. The purpose was to fill a critical knowledge gap, providing insights into how various host factors influence SNOT-22 scores which seek to serve as reference for clinical studies, facilitating comparisons of symptom severity and aid in patient counselling based on specific score patterns. METHODS: One thousand and twelve adults meeting inclusion criteria participated in the study. Participants provided demographic information, occupation details, addiction history, and medical background. They completed SNOT-22 questionnaire, grading their symptoms on Likert scale of 0-5 based on severity experienced in the past 2 weeks. The collected data were analysed to derive meaningful insights. RESULTS: Mean SNOT-22 score for the study population was 6.80, with 90% scoring below 15, and 40% within 0-3 range. Females exhibited significantly lower mean scores than males. Residents of rural areas reported higher scores than urban counterparts. Education levels had no significant influence on scores. Occupational exposure to aeroallergens, addiction (especially tobacco), and a history of allergies, bronchial asthma, or atopy were associated with significantly higher SNOT-22 scores. Principal component analysis identified four distinct domains, with the nasal symptom domain consistently emerging as the major contributor to differences in subgroups with significantly different total SNOT-22 scores. CONCLUSION: The normative data and subgroup analyses established in this study serve as a foundation for future research, aiding clinicians in predicting symptoms and providing tailored counselling for individuals with sino-nasal pathologies.

Hope and its relationship with treatment/ physical related factors in lung cancer patients receiving immunotherapy.

BACKGROUNDPURPOSE: Immunotherapy is a new treatment option for patients with Lung Cancer (LC). However, relatively limited research has explored about patients' perception of hope and its associated factors during the process. This study aimed to examine level of perceived hope and the factors related to hope, with a particular focus on treatment and physically related factors, in LC patients receiving immunotherapy. METHODS: A cross-sectional study was conducted and patients who had already received at least one immunotherapy cycle were recruited from two hospitals in northern Taiwan. The questionnaire included a background information form, the Herth's Hope Index, and the Symptom Severity Scale. Stepwise regression was applied to identify the most robust factors related to level of hope in the participants. RESULTS: A total of 130 patients were recruited. Overall, patients reported moderate to high levels of hope and mild symptoms. Fatigue, weakness, appearance changes, pruritus, and shortness of breath were identified as the most severe symptoms. Further regression analysis showed that patients with poor performance status, less immunotherapy cycles, higher level of fatigue, and more severe pruritus reported to have lower level of hope which explained 47% of the variances. CONCLUSIONS: This study revealed that lung cancer patients undergoing immunotherapy had moderate level of hope. Patients' performance status, selected symptoms and times of receiving immunotherapy were the robust factors related to hope. Systematic assessment of patients' symptoms and the development of appropriate interventions to reduce distress and enhance hope are strongly recommended for both clinical care and research.

Effectiveness of preoperative micronized purified flavonoid fraction treatment and sucralfate-based rectal ointment on hemorrhoidal disease: A case-matched analysis.

BACKGROUND: Hemorrhoidal disease (HD) significantly impacts patients' quality of life. This study aimed to evaluate the effectiveness of preoperative treatment with the micronized purified flavonoid fraction (MPFF) and a sucralfate-based rectal ointment in managing HD symptoms and reducing interventions. METHODS: A prospective quasi-experimental study including consecutive cases and controls matched on the basis of sex was performed in a tertiary referral center. Cases received systemic and local therapy for HD, consisting of a rectal ointment containing 3% sucralfate and herbal extracts plus MPFF, in addition to conservative therapy, while controls received conservative therapy alone. The hemorrhoidal disease symptom score (HDSS), the Short Health Scale for HD (SHS-HD) score, and the Vaizey Incontinence Score were used to evaluate symptoms severity and their impact on quality of life and continence. Intervention requirements were assessed at baseline (T0) and after 60 days of treatment (T1). RESULTS: Between January and December 2023, a total of 98 patients were assessed for eligibility. After exclusions, 56 patients were enrolled, with 28 in each group. Significant improvements were observed in HD symptom scores from T0 to T1: the intervention group showed a mean change in HDSS of -9 [95% confidence interval (CI) -10 to -8], and the control group showed no significant change (mean change of 0; 95% CI -1.5 to 0). At T1, a higher proportion of patients in the intervention group underwent less invasive interventions compared with controls (18% versus 11%). Age, treatment group, and baseline symptom severity significantly predicted post-treatment symptom scores. CONCLUSIONS: In our study the preoperative treatment with MPFF and a sucralfate-based rectal ointment demonstrated clinical benefits in managing HD symptoms and reducing interventions. Further prospective trials are warranted to confirm and explore additional therapeutic strategies.

Behavioral activation is associated with post-disaster mental health: Secondary longitudinal analysis from a population-based study.

OBJECTIVE: Interventions in post-disaster environments may be accelerated by identifying protective behavioral factors adding incremental value to models of psychopathology using longitudinal methods. One protective behavior applicable to post-disaster contexts is behavioral activation (BA). BA is defined here as a behavioral pattern involving presence of valued activity engagement. While relevant post-disaster, the incremental value of BA behaviors in predicting longitudinal post-disaster outcomes is not well understood. We hypothesized that higher baseline engagement in behaviors consistent with a BA framework would predict decreased posttraumatic stress disorder (PTSD) symptom severity, depression symptom severity, and sleep disturbance approximately 3, 6, and 12 months after hurricane survivors completed baseline measures. METHODS: The current study is a secondary analysis from a randomized controlled trial of a disaster mental health digital intervention. Participants completed surveys at baseline and approximately 3, 6, and 12 months post-enrollment. Correlations and hierarchical regression analyses were calculated following data screening to predict PTSD symptom severity, depression symptom severity, and sleep disturbances. RESULTS: Controlling for alcohol use, prior trauma, displacement, and intervention condition, higher baseline BA consistently predicted less PTSD symptom severity, depression symptom severity, and sleep disturbances. CONCLUSION: Results suggest that post-disaster interventions should consider addressing BA. The study provides evidence that BA is potentially an important protective factor longitudinally predicting sleep disturbances and psychopathology after natural disasters.

Association between cumulative trauma and severity of psychotic symptoms among patients experiencing psychosis.

Psychosis-related trauma is a prevalent condition that significantly impacts patients and often leads to an increased reliance on psychiatric nursing services. This study aimed to provide a deeper understanding of the complex relationship between cumulative trauma and the severity of psychosis symptoms among patients experiencing psychosis. Utilizing a cross-sectional research design, data were collected from 76 community-dwelling patients recruited. Patients' sociodemographic and clinical data, Cumulative Trauma Measure scores, and psychosis symptom severity scale scores were collected. A significant difference was observed between collective identity trauma and the presence of hallucinations and abnormal psychomotor behavior (Z = 4.1 and 2.69, respectively). Significant differences were also observed between role identity trauma and the presence of delusions and abnormal psychomotor behavior (Z = 3.86 and 2.06, respectively); attachment trauma and the presence of hallucinations, abnormal psychomotor behavior, and mania (Z = 2.16, 2.12, and 2.11, respectively); and survival trauma and the presence of disorganized speech (Z = 2.61). Moreover, there was a significant difference regarding secondary trauma and the presence of hallucinations, delusions, disorganized speech, abnormal psychomotor behavior, depression, and mania (Z = 4.29, 2.15, 2.11, 2.12, 4.42, and 3.39, respectively). In conclusion, total cumulative trauma explained 44.2 %, 25.8 %, 24.7 %, 16.2 %, 13.6 %, and 13.2 % of the severity of delusion, hallucination, depression, mania, abnormal psychomotor behavior, and disorganized speech, respectively, among patients experiencing psychosis. Implication for nursing practice, by recognizing the nuanced interplay between cumulative trauma and diverse manifestations of psychosis symptoms, nursing professionals can tailor their approaches to provide more holistic and patient-centered care that may significantly contribute to improved patient outcomes and the overall well-being of individuals navigating the complex landscape of psychosis-related trauma.

Prospective Associations Between Personality Traits and Major Depressive Disorder Symptom Severity: The Mediating Role of Illness Representations.

Major depressive disorder (MDD) patients' personality traits and illness representations are linked to MDD severity. However, the associations between personality and illness representations in MDD and the mediating role of illness representations between personality and MDD severity have not been investigated. This study aimed to prospectively investigate the aforementioned associations and the possible mediating role of illness representations between personality and MDD severity. One hundred twenty-five patients with a MDD diagnosis, aged 48.18 ± 13.92 (84% females), participated in the study. Personality traits were measured with the Traits Personality Questionnaire at baseline. Illness representations were measured with the Illness Perception Questionnaire-Mental Health about five months later (mean = 5.08 ± 1.14 months). MDD severity was measured about 10 months after the baseline assessment (mean = 9.53 ± 2.36 months) with the Beck Depression Inventory. SPSS 29 and AMOS 27 were used to conduct correlational and parallel mediation analyses. According to the results, Neuroticism was positively and Extraversion was negatively linked to MDD severity. Negative MDD impact representations fully mediated these associations. Neuroticism and Extraversion are linked to future MDD severity through patients' representations of MDD's impact. Restructuring maladaptive representations about MDD's impact can be a promising way to reduce symptom severity in patients with high Neuroticism and low Extraversion levels.

Optimizing geriatric palliative care in Egypt: Comprehensive patient and family perspectives.

OBJECTIVES: In Egypt, palliative care for geriatric patients is understudied, necessitating exploration for service optimization. Amidst rising chronic illnesses and aging, understanding perspectives of geriatric patients and families is crucial for targeted improvements. This study aims to explore geriatric patients' and their families' perspectives on palliative care in Egypt, seeking opportunities to optimize service delivery for the elderly. METHODS: Employing a cross-sectional design with 110 geriatric patients and an equal number of family caregivers from the Damietta Oncology Institute and the pain treatment clinics for cancer patients at Zagazig University Hospital, the study focuses on a specialized pain clinic. Validated tools (Palliative Care Outcome Scale, Family Satisfaction with End-of-Life Care [FAMCARE] Scale, Edmonton Symptom Assessment System [ESAS], Caregiver Strain Index [CSI]) assess quality of life, family satisfaction, symptom severity, and caregiver strain. RESULTS: Geriatric patients (mean age: 65.0 ± 8.1 years; 45.5% male, 55.5% female) have diverse diagnoses (e.g., breast cancer 22%). Palliative care outcomes reveal challenges: low emotional well-being (2.6 ± 0.0) and alarming overall quality of life (1.8 ± 0.0). Family dissatisfaction (FAMCARE) is pervasive (total mean score 2.6 ± 0.5). Symptom severity (ESAS) is high, and caregiver strain (CSI) is notable (8.5 ± 2.2). SIGNIFICANCE OF THE RESULTS: The findings underscore the significance of the challenges faced by geriatric patients and caregivers in palliative care. Patients confront considerable symptom burdens and emotional distress, while caregivers experience notable strain. Urgently needed are targeted interventions designed to enhance patient well-being, alleviate caregiver burden, and elevate satisfaction. The critical importance of implementing these interventions promptly is highlighted, as they are instrumental in improving the overall care experience for geriatric patients and their caregivers. Moreover, the results underscore the imperative of developing comprehensive support mechanisms to address the intricate dimensions of palliative care, ultimately contributing to a more compassionate and effective care continuum.
