The most frequently mutated gene was PIM1 (9/15, 60%), followed by MYD88L265P and CD79B (8/15, 53% each). In 6 cases, MYD88L265P and CD79B mutations were detected concomitantly. We also identified recurrent mutations in IRF4 , TMEM30A , BTG2 , and ETV6 loci (4/15, 27% each) and novel driver mutations in NOTCH2 , CCND3 , and GNA13 , and an IRF4 translocation in 1 case each. The mutational profile was similar in patients with and without evidence of hemophagocytic syndrome and in cases with or without dissemination of tumor cells outside the vessels. Our results confirm the relevance of mutations in B-cell receptor/nuclear factor-κB signaling and immune escape pathways in IVLBCL and identify novel driver alterations. The similar mutational profile in tumors with extravascular dissemination suggests that these cases may also be considered in the spectrum of IVLBCL.

We aimed to explore the heterogeneous treatment effects (HTEs) for spironolactone treatment in patients with Heart failure with preserved ejection fraction (HFpEF) and examine the efficacy and safety of spironolactone medication, ensuring a better individualized therapy.

We used the causal forest algorithm to discover the heterogeneous treatment effects (HTEs) from patients in the Treatment of Preserved Cardiac Function Heart Failure with an Aldosterone Antagonist (TOPCAT) trial. Cox regressions were performed to assess the hazard ratios (HRs) of spironolactone medication for cardiovascular death and drug discontinuation in each group. The causal forest model revealed three representative covariates and participants were partitioned into four subgroups which were Group 1 (baseline BMI≤31.71kg/m

and baseline ALP≤80U/L, n=759); Group 2 (BMI≤31.71kg/m

and ALP>80U/L, n=1088); Group 3 (BMI>31.71kg/m

, and WBC≤6.6 cells/μL, n=633); Group 4 (BMI>31.71kg/m

and WBC>6.6 cells/μL, n=832), respectchine learning model could be meaningful for improved categorization of patients with HFpEF, ensuring a better individualized therapy in the clinical setting.Haptophytes are one of the most ecologically successful phytoplankton groups in the modern ocean and tend to maintain balanced and stable communities across various environments. However, little is known about the mechanisms that enable community stability and ecological success. To reveal the community characteristics and interactions among haptophytes, we conducted comprehensive observations from the upstream to downstream regions of the Kuroshio Current. Haptophyte abundance and taxonomy were assessed using quantitative polymerase chain reaction and metabarcoding of 18S rRNA sequences, respectively. The haptophyte community structure changed abruptly at sites on the shelf-slope of the East China Sea, indicating the strong influence of shelf waters with high phytoplankton biomass on downstream communities. Correlation network analysis combined with the phylogeny suggested that haptophytes can coexist with their close relatives, possibly owing to their nutritional flexibility, thereby escaping from resource competition. Consistently, some noncalcifying haptophyte genera with high mixotrophic capacities such as Chrysochromulina constituted a major component of the co-occurrence network, whereas coccolithophores such as Emiliania/Gephyrocapsa were rarely observed. Our study findings suggest that noncalcifying haptophytes play crucial roles in community diversity and stability, and in sustaining the food web structure in the Kuroshio ecosystems.Breast cancer is a major cause of cancer-related morbidity and mortality in women. Estrogen receptor-positive breast cancer accounts for roughly 70-80% of breast tumors, and estrogen receptor alpha (ERα) has been considered as a key driver in promoting breast cancer progression. In the present study, we identified USP37 as a novel modulator in modulating ERα ubiquitination and stability. The expression of USP37 was upregulated in ERα-positive breast cancer and correlated with ERα protein level. High expression of USP37 was associated with unfavorable prognosis. USP37 depletion resulted in significantly decreased ERα protein level, ERα target genes expression as well as the estrogen response element activity in breast cancer cells. Further mechanistic study revealed the interaction between USP37 and ERα USP37 regulated ERα signaling through modulating protein stability instead of gene expression, in which it stabilized ERα protein via inhibiting the K48-specific poly-ubiquitination process. Additionally, USP37 depletion led to growth inhibition and cell cycle arrest of ERα-positive breast cancer cells, which could be further rescued by ERα overexpression. Overall, our study proposed a novel post-translational mechanism of ERα in promoting breast cancer progression. Targeting USP37 may be proved to be a promising strategy for patients with ERα-positive breast cancer.Objectives During their domestic quarantine, Covid-19 patients face major physical, psychological and social challenges. The description of support needs and specific topics brought to supportive conversations will be used to add to the body of knowledge about stressors and resources. Methods A total of 109 telephone conversations with 69 quarantined Corona patients were documented by psychotherapists and physicians at Heidelberg University Hospital from November 2020 to April 2021. Subsequently, clinical documentations were analyzed according to a qualitative content analysis. Results Most physical complaints related to cardio-respiratory symptoms (29 %), previous illnesses (24 %), and exhaustion or fatigue (16 %). selleck kinase inhibitor On the psychological level, patients reported mainly anxiety (31 %) and depressive symptoms (16 %). On a social level, patients described stress related to family (56 %), work (20 %), and time in quarantine (16 %). Social support, individual coping strategies, a positive prognosis on the course of the corona disease, psychotherapy, and satisfactory medical care were mentioned as relieving factors. Therapeutic interventions aimed at stabilization and consisted of psychoeducation, relaxation techniques, and general counseling. Conclusions The study shows that physical complaints, psychological symptoms, and social factors are brought into telephone support conversations. The support offer met a high demand and was well accepted.Objectives Considering direct and indirect evidence of associations between deficits in personality functioning and high somatic morbidity, our exploratory study determined whether and, if so, which physical illnesses may be associated with impairments in personality functioning. Method A large sample of diagnostically heterogeneous psychotherapy inpatients (N = 5401) was assessed with the short version of the Structural Questionnaire of the Operationalized Psychodynamic Diagnosis (OPD-SQS) and the Work Ability Index (WAI). In addition, discharge diagnoses were recorded. For a subsample (N = 2582), levels of personality functioning were assessed by their therapists according to the OPD system. Results While consistent associations were found between personality functioning and neurological, urogenital, dermatological, and musculoskeletal disorders, findings on possible associations with other disorders revealed inconsistencies. The number of diseases as surrogate marker for disease burden was significantly associated with several indicators of personality functioning. Conclusions Our results suggest associations between impairments in personality functioning and poor physical health. We discuss potential mechanisms as well as clinical implications.Objectives This qualitative study aimed to assess the need for information in eating disorders from the perspective of relatives. Further, it examined the question how publicly available information about eating disorders may contribute to psychoeducation. Methods Thirteen relatives of patients with anorexia nervosa and bulimia nervosa were interviewed based on a semistructured interview guide. The interview transcripts were interpreted by using a structuring qualitative content analysis. Results Relatives showed a high need for information throughout the entire course of illness. More information about the disorder itself and its potential treatment were requested. The needs were addressed to public services and to family doctors as well as paediatricians. Conclusions Relatives as well as family doctors and paediatricians play an important role in the detection and support of the treatment of eating disorders. In view of the high rate of cases diagnosed late or not at all, psychoeducational offers require further expansion.Vimentin expression in tumor tissues and the tumor-stroma ratio (TSR) have been demonstrated as strong prognostic factors for cancer patients, but whether they are predictive markers of neoadjuvant chemoradiotherapy (nCRT) outcome in locally advanced rectal cancer (LARC) patients is poorly understood. This study aimed to explore the predictive significance of vimentin and TSR combined for nCRT response in LARC patients. Imaging mass cytometry (IMC) was performed to determine the association of vimentin and TSR with nCRT response in six LARC patients [three achieved pathological complete response (pCR), three did not]. Immunohistochemistry (IHC) for vimentin and TSR on biopsy tissues before nCRT and logistic regression analysis were performed to further evaluate their predictive value for treatment responses in a larger patient cohort. A trend of decreased vimentin expression and increased TSR in the pCR group was revealed by IMC. In the validation group, vimentin [odds ratio (OR) 0.260, 95% confidence interval (CI) 0.102-0.602, p = 0.002] and TSR (OR 4.971, 95% CI 1.933-15.431, p = 0.002) were associated with pCR by univariate analysis. Patients in the vimentin-low/TSR-low or vimentin-high/TSR-high (OR 5.211, 95% CI 1.248-35.582, p = 0.042) and vimentin-low/TSR-high groups (OR 11.846, 95% CI 3.197-77.079, p = 0.001) had significantly higher odds of pCR. By multivariate analysis, only the combination of vimentin and TSR was an independent predictor for nCRT response (OR 9.324, 95% CI 2.290-63.623, p = 0.006). Our study suggested that the combined assessment of vimentin and TSR can provide additive significance and may be a promising indicator of nCRT response in LARC patients.

SHANK3 is an important excitatory postsynaptic scaffold protein, and its mutations lead to genetic cause of neurodevelopmental diseases including autism spectrum disorders (ASD), Philan McDermid syndrome (PMS), and intellectual disability (ID). Early prevention and treatment are important for Shank3 gene mutation disease. Swimming has been proven to have a positive effect on neurodegenerative diseases.

Shank3 gene exon 11-21 knockout rats were intervened by a 40 min/day, 5day/week for 8-week protocol. After the intervention, the rats were tested to behavioral measures such as learning and memory, and the volume and H-spectrum of the brain were measured using MRI; hippocampal dendritic spines were measured using Golgi staining and laser confocal.

The results showed that Shank3-deficient rats had significant deficits in social memory, object recognition, and water maze learning decreased hippocampal volume and number of neurons, and lower levels of related scaffold proteins and receptor proteins were found in Shank3-deficient rats.
