A Predictive Model of Risk Factors for Conversion From Major Depressive Disorder to Bipolar Disorder Based on Clinical Characteristics and Circadian Rhythm Gene Polymorphisms. Front Psychiatry 2022; 13:843400. [PMID: 35898634 PMCID: PMC9309512 DOI: 10.3389/fpsyt.2022.843400] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/25/2021] [Accepted: 06/08/2022] [Indexed: 11/13/2022] Open
Abstract
BACKGROUND Bipolar disorder (BD) is easy to be misdiagnosed as major depressive disorder (MDD), which may contribute to a delay in treatment and affect prognosis. Circadian rhythm dysfunction is significantly associated with conversion from MDD to BD. So far, there has been no study that has revealed a relationship between circadian rhythm gene polymorphism and MDD-to-BD conversion. Furthermore, the prediction of MDD-to-BD conversion has not been made by integrating multidimensional data. The study combined clinical and genetic factors to establish a predictive model through machine learning (ML) for MDD-to-BD conversion. METHOD By following up for 5 years, 70 patients with MDD and 68 patients with BD were included in this study at last. Single nucleotide polymorphisms (SNPs) of the circadian rhythm genes were selected for detection. The R software was used to operate feature screening and establish a predictive model. The predictive model was established by logistic regression, which was performed by four evaluation methods. RESULTS It was found that age of onset was a risk factor for MDD-to-BD conversion. The younger the age of onset, the higher the risk of BD. Furthermore, suicide attempts and the number of hospitalizations were associated with MDD-to-BD conversion. Eleven circadian rhythm gene polymorphisms were associated with MDD-to-BD conversion by feature screening. These factors were used to establish two models, and 4 evaluation methods proved that the model with clinical characteristics and SNPs had the better predictive ability. CONCLUSION The risk factors for MDD-to-BD conversion have been found, and a predictive model has been established, with a specific guiding significance for clinical diagnosis.

Abstract
Background: Breast cancer bone metastasis and osteoporosis are both severe diseases that seriously threaten human health. These diseases are closely associated with osteolytic lesions. And osteoclasts are the key targets of this pathological process. Given the lack of effective preventive or treatment options against these diseases, the exploitation of new pharmacological agents is critically required. Method: We assessed the efficacy of punicalin on receptor activator of nuclear factor-κB ligand (RANKL)-mediated osteoclast formation, F-actin ring formation, gene expression, bone resorption, nuclear factor-κB (NF-κB) as well as on mitogen-activated protein kinase (MAPK) signaling pathways and molecular docking in vitro. The impact of punicalin on breast cancer-induced osteoclastogenesis, breast cancer cell proliferation, and apoptosis were examined. Transwell assays were also performed. Moreover, we evaluated in vivo effects of punicalin in postmenopausal osteoporosis models and breast cancer bone metastasis model by micro-CT scanning and histomorphometry. Results: Punicalin inhibited osteoclast formation, F-actin ring formation, bone resorption, as well as osteoclast-related gene expression by suppressing the NF-κB signaling pathway. In vitro, punicalin also suppressed the breast cancer-induced osteoclastogenesis, and proliferation, migration as well as invasion of MDA-MB-231 cells and dose-dependently promoted their apoptosis. In vivo, punicalin significantly suppressed breast cancer-induced osteolysis, breast cancer-associated bone metastasis, and ovariectomized (OVX)-mediated osteoporosis by repressing osteoclast and breast cancer cell. Conclusion: Punicalin is expected to offer a novel treatment for the prevention of osteolysis diseases, including osteoporosis and breast cancer-associated osteolysis.

Abstract
Abstract
Background
The geriatric day hospital (GDH) provides outpatient geriatric medical, nursing and rehabilitation care to older adults. The aim of this study was to assess whether medication optimisation occurs in this setting. We believe the GDH would be an ideal location for mediation optimisation due to the stable community dwelling patients and close follow up by specialised physicians.
Methods
Electronic patient records of the new patients ≥65 years seen in the GDH over a 3-month period were reviewed. Potentially inappropriate prescriptions (PIPs) and potentially prescribing omissions (PPOs) were identified using the STOPP/START prescribing tool on admission to the GDH and again at discharge from the GDH.
Results
One-hundred and sixty-seven patient records were reviewed; mean age 80.8 (SD6.5) years, 62.9% female, median clinical frailty scale score 6 (IQR5–6), mean number of conditions 5.79 (SD3), mean number of medications 7.57 (SD3.7). Patients had a median of 4 (IQR2–7) consultations. The number of patients prescribed at least 1 STOPP-PIP reduced by 10% (42.4% vs 38%; p < 0.001). Vasodilator drugs in patients with orthostatic hypotension were deprescribed most frequently (6.5% vs 3%; p < 0.001). PPOs were reduced by 36% (47.5% vs 30.6%;p < 0.001). The largest improvement was identified in the prescription of vitamin D in patients experiencing falls (17.4% vs 13.8%;p < 0.001). Logistic regression was performed to ascertain the influence of age, gender, falls, dementia, co-morbidity number and medication number on the likelihood of a patient experiencing a PIP or PPO. For every medication prescribed, the odds of experiencing a PIP increased by 11.8% (OR1.187, 95%CI 1.052–1.339). Being female increased the odds of experiencing a PPO by 21.7% (OR2.17, 95%CI 10.53–4.468).
Conclusion
Medication optimisation is key in avoiding side effects from potentially inappropriate medications. The frequency of patient attendances coupled with geriatricians’ expertise makes the GDH an ideal setting for medication optimisation in multi-morbid frail community-dwelling older adults.

Abstract
We report a general palladium-catalyzed one-pot procedure for the synthesis of phosphonates, phosphinates and phosphine oxides from phenols mediated by sulfuryl fluoride. It features mild conditions, broad substrate scope, high functionality tolerance and water insensitivity. The utility of this procedure has been well demonstrated by gram-scale synthesis, sequential synthesis of click chemistry building blocks, late-stage decoration of drugs and natural products and on-DNA synthesis of phosphine oxide for a DNA-encoded library (DEL).

Abstract
DNA-encoded combinatorial chemical library (DEL) technology, an approach that combines the power of genetics and chemistry, has emerged as an invaluable tool in drug discovery. Skeletal diversity plays a fundamental importance in DEL applications, and relies heavily on novel DNA-compatible chemical reactions. We report herein a phylogenic chemical transformation strategy using DNA-conjugated benzoyl hydrazine as a common versatile precursor in azole chemical expansion of DELs. DNA-compatible reactions deriving from the common benzoyl hydrazine precursor showed excellent functional group tolerance with exceptional efficiency in the synthesis of various azoles, including oxadiazoles, thiadiazoles, and triazoles, under mild reaction conditions. The phylogenic chemical transformation strategy provides DELs a facile way to expand into various unique chemical spaces with privileged scaffolds and pharmacophores.

Abstract
OBJECTIVE To uncover the biological role of microRNA-200a-3p (miRNA-200a-3p) in the progression of non-small cell lung cancer (NSCLC) and the underlying mechanism. PATIENTS AND METHODS The expression levels of miRNA-200a-3p and IRS2 in NSCLC tissues and cell lines were examined through quantitative Real Time-Polymerase Chain Reaction (qRT-PCR). The correlation between the miRNA-200a-3p level and pathological characteristics of NSCLC patients was analyzed. The prognostic value of miRNA-200a-3p in NSCLC was assessed through the Kaplan-Meier method. The potential interaction between miRNA-200a-3p and IRS2 was explored through Dual-Luciferase Reporter Gene Assay and Spearman correlation test. The regulatory effects of miRNA-200a-3p/IRS2 on the proliferative, migratory, and invasive abilities of NSCLC were evaluated by Cell Counting Kit-8 (CCK-8) and the transwell assay. The protein levels of the epithelial-mesenchymal transition (EMT)-related genes in NSCLC cells influenced by miRNA-200a-3p were detected by Western blot. RESULTS MiRNA-200a-3p was downregulated in NSCLC tissues and cell lines. The expression level of miRNA-200a-3p was related to tumor size, TNM staging, and lymphatic metastasis of NSCLC. The low level of miRNA-200a-3p predicted worse prognosis in NSCLC patients. The overexpression of miRNA-200a-3p inhibited A549 cells from proliferating, migrating, and invading. The protein levels of E-cadherin were upregulated, while N-cadherin and Vimentin were downregulated in A549 cells overexpressing miRNA-200a-3p. The Dual-Luciferase Reporter Gene Assay verified the binding between miRNA-200a-3p and IRS2. The level of IRS2 was negatively regulated by miRNA-200a-3p. Moreover, the overexpression of IRS2 could reverse the regulatory role of miRNA-200a-3p in the cellular behaviors of A549 cells. CONCLUSIONS MiRNA-200a-3p suppresses the proliferative, migratory, and invasive abilities of NSCLC by targeting IRS2, thus alleviating the progression of NSCLC.
