Adsorption of typical NDMA precursors by superfine powdered activated carbon: Critical role of particle size reduction.

Control of N-nitrosodimethylamine (NDMA) in drinking water could be achieved by removing its precursors as one practical way. Herein, superfine powdered activated carbons with a diameter of about 1 µm (SPACs) were successfully prepared by grinding powdered activated carbon (PAC, D50=24.3 µm) and applied to remove model NDMA precursors, i.e. ranitidine (RAN) and nizatidine (NIZ). Results from grain diameter experiments demonstrated that the absorption velocity increased dramatically with decreasing particle size, and the maximum increase in k2 was 26.8-folds for RAN and 33.4-folds for NIZ. Moreover, kinetic experiments explained that rapid absorption could be attributed to the acceleration of intraparticle diffusion due to the shortening of the diffusion path. Furthermore, performance comparison experiments suggested that the removal of RAN and NIZ (C0=0.5 mg/L) could reach 61.3% and 60%, respectively, within 5 min, when the dosage of SAPC-1.1 (D50=1.1 µm) was merely 5 mg/L, while PAC-24.3 could only eliminate 17.5% and 18.6%. The adsorption isotherm was well defined by Langmuir isotherm model, indicating that the adsorption of RAN/NIZ was a monolayer coverage process. The adsorption of RAN or NIZ by SAPC-1.1 and PAC-24.3 was strongly pH dependent, and high adsorption capacity could be observed under the condition of pH > pka+1. The coexistence of humic acid (HA) had no significant effect on the adsorption performance because RAN/NIZ may be coupled with HA and removed simultaneously. The coexistence of anions had little effect on the adsorption also. This study is expected to provide an alternative strategy for drinking water safety triggered by NDMA.

Microglia lactylation in relation to central nervous system diseases.

The development of neurodegenerative diseases is closely related to the disruption of central nervous system homeostasis. Microglia, as innate immune cells, play important roles in the maintenance of central nervous system homeostasis, injury response, and neurodegenerative diseases. Lactate has been considered a metabolic waste product, but recent studies are revealing ever more of the physiological functions of lactate. Lactylation is an important pathway in lactate function and is involved in glycolysis-related functions, macrophage polarization, neuromodulation, and angiogenesis and has also been implicated in the development of various diseases. This review provides an overview of the lactate metabolic and homeostatic regulatory processes involved in microglia lactylation, histone versus non-histone lactylation, and therapeutic approaches targeting lactate. Finally, we summarize the current research on microglia lactylation in central nervous system diseases. A deeper understanding of the metabolic regulatory mechanisms of microglia lactylation will provide more options for the treatment of central nervous system diseases.

Chondroitinase ABC combined with Schwann cell transplantation enhances restoration of neural connection and functional recovery following acute and chronic spinal cord injury.

JOURNAL/nrgr/04.03/01300535-202505000-00029/figure1/v/2024-07-28T173839Z/r/image-tiff Schwann cell transplantation is considered one of the most promising cell-based therapy to repair injured spinal cord due to its unique growth-promoting and myelin-forming properties. A the Food and Drug Administration-approved Phase I clinical trial has been conducted to evaluate the safety of transplanted human autologous Schwann cells to treat patients with spinal cord injury. A major challenge for Schwann cell transplantation is that grafted Schwann cells are confined within the lesion cavity, and they do not migrate into the host environment due to the inhibitory barrier formed by injury-induced glial scar, thus limiting axonal reentry into the host spinal cord. Here we introduce a combinatorial strategy by suppressing the inhibitory extracellular environment with injection of lentivirus-mediated transfection of chondroitinase ABC gene at the rostral and caudal borders of the lesion site and simultaneously leveraging the repair capacity of transplanted Schwann cells in adult rats following a mid-thoracic contusive spinal cord injury. We report that when the glial scar was degraded by chondroitinase ABC at the rostral and caudal lesion borders, Schwann cells migrated for considerable distances in both rostral and caudal directions. Such Schwann cell migration led to enhanced axonal regrowth, including the serotonergic and dopaminergic axons originating from supraspinal regions, and promoted recovery of locomotor and urinary bladder functions. Importantly, the Schwann cell survival and axonal regrowth persisted up to 6 months after the injury, even when treatment was delayed for 3 months to mimic chronic spinal cord injury. These findings collectively show promising evidence for a combinatorial strategy with chondroitinase ABC and Schwann cells in promoting remodeling and recovery of function following spinal cord injury.

Pro-resolving lipid mediator reduces amyloid-ß42-induced gene expression in human monocyte-derived microglia.

JOURNAL/nrgr/04.03/01300535-202503000-00031/figure1/v/2024-06-17T092413Z/r/image-tiff Specialized pro-resolving lipid mediators including maresin 1 mediate resolution but the levels of these are reduced in Alzheimer's disease brain, suggesting that they constitute a novel target for the treatment of Alzheimer's disease to prevent/stop inflammation and combat disease pathology. Therefore, it is important to clarify whether they counteract the expression of genes and proteins induced by amyloid-ß. With this objective, we analyzed the relevance of human monocyte-derived microglia for in vitro modeling of neuroinflammation and its resolution in the context of Alzheimer's disease and investigated the pro-resolving bioactivity of maresin 1 on amyloid-ß42-induced Alzheimer's disease-like inflammation. Analysis of RNA-sequencing data and secreted proteins in supernatants from the monocyte-derived microglia showed that the monocyte-derived microglia resembled Alzheimer's disease-like neuroinflammation in human brain microglia after incubation with amyloid-ß42. Maresin 1 restored homeostasis by down-regulating inflammatory pathway related gene expression induced by amyloid-ß42 in monocyte-derived microglia, protection of maresin 1 against the effects of amyloid-ß42 is mediated by a re-balancing of inflammatory transcriptional networks in which modulation of gene transcription in the nuclear factor-kappa B pathway plays a major part. We pinpointed molecular targets that are associated with both neuroinflammation in Alzheimer's disease and therapeutic targets by maresin 1. In conclusion, monocyte-derived microglia represent a relevant in vitro microglial model for studies on Alzheimer's disease-like inflammation and drug response for individual patients. Maresin 1 ameliorates amyloid-ß42-induced changes in several genes of importance in Alzheimer's disease, highlighting its potential as a therapeutic target for Alzheimer's disease.

The chemically stable analogue of resolvin D1 ameliorates experimental autoimmune encephalomyelitis by mediating the resolution of inflammation.

While Resolvin D1 (RvD1) shows promise in resolving inflammation in experimental autoimmune encephalomyelitis (EAE), its pro-resolving roles on dendritic cells (DCs) remain unknown, and the chemical instability of RvD1 poses significant challenges to its drug development. This study aims to investigate whether 4-(2'-methoxyphenyl)-1-[2'-[N-(2″-pyridinyl)-p-fluorobenzamido]ethyl]piperazine (p-MPPF), a novel chemically stable analogue of RvD1, can play a pro-resolving role in EAE, particularly on DCs, and if p-MPPF could serve as a potential substitute for RvD1. We showed that both RvD1 and p-MPPF mediated the resolution of inflammation in EAE, as evidenced by ameliorated EAE progression, attenuated pathological changes in the spinal cord, altered cytokine expression profile in serum, and reduced proportion of pro-inflammatory immune cells in the spleen. Utilizing DCs derived from both the spleen and bone marrow of EAE, our investigation showed that RvD1 and p-MPPF prevented DC maturation, decreased pro-inflammatory cytokine secretion, shifted DCs away from a pro-inflammatory phenotype, increased the phagocytosis capacity of DCs, and suppressed their ability to induce differentiation of CD4+ T cells into Th1 and Th17 subsets. For underlying intracellular mechanisms, we found that RvD1 and p-MPPF down-regulated the lactate dehydrogenase A signaling pathways. Comparisons between RvD1 and p-MPPF showed that they exerted overlapped pro-resolving effects to a large extent. This study demonstrates that both RvD1 and p-MPPF exert therapeutic effects on EAE by mediating inflammation resolution, which is closely associated with modulating DC immune function towards a tolerogenic phenotype. SPM mimetics may serve as a more promising therapeutic drug.

Clinical value of complete blood count ratio in benign and malignant thyroid diseases.

OBJECTIVE: To investigate the clinical value of blood routine derivative biomarkers and thyroid function biomarkers in differentiating different thyroid diseases. METHODS: The differences of blood routine derived indexes neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), lymphocyte-to-monocyte ratio (LMR), platelet-large cell rate (P-LCR) and thyroid function indexes between benign and malignant thyroid diseases were compared, and the differences of each index between different benign thyroid diseases were further compared. Univariate regression analysis model was used to analyze the clinical value of various indexes. Receiver operating characteristic curve (ROC) was used to calculate the area under the curve (AUC). RESULTS: There were statistically significant differences in PLR, NLR and P-LCR between patients with benign and malignant thyroid diseases (P < 0.05 for each). The results of univariate logistic regression analysis showed that P < 0.05 for all indicators except LMR, when PLR and NLR value increased by 1, the risk of thyroid malignancy decreased by 1 % and 21 %, when P-LCR value increased by 1, the risk of thyroid malignancy increased by 4 %. CONCLUSIONS: PLR, NLR and P-LCR are helpful to distinguish different benign thyroid diseases and to diagnose benign and malignant thyroid diseases.

[Analysis of curative effect of orbital apex syndrome caused by sinus disease].

Objective:To compare the efficacy of endoscopic sinus surgery and conservative treatment for orbital apex syndrome caused by sinus lesions. Methods:The clinical data of 56 patients with orbital apex syndrome caused by sinus lesions who were admitted to the First Affiliated Hospital of Zhengzhou University from January 2018 to August 2023 were retrospectively analyzed and divided into a surgical group of 21 cases and a conservative group of 35 cases. The clinical features and prognosis of the two groups were compared. Results:Among the sinus lesions in the surgical group, 61.9% were fungal sinusitis, 28.6% were bacterial sinusitis, and 9.5% were sphenoid sinus tumors. In the conservative group, non-fungal sinusitis accounted for 65.7% and fungal sinusitis accounted for 34.3%. In addition to sinus lesions, patients had underlying diseases. In the surgical group, 71.4% had hypertension and 80.9% had diabetes; in the conservative group, 28.6% had hypertension and 42.9% had diabetes. After a follow-up of 1 month to 5 years, the symptom improvement rate in the surgical group was 85.7%, with 1 case of recurrence. No recurrence was found after reoperation, while the symptom improvement rate in the conservative group was 22.9%, and 6 cases recurred after symptom improvement, and were transferred to rhinology department. No recurrence was seen after surgery. Conclusion:Most of the sinus lesions in this study were fungal sinusitis. In addition, patients with underlying diseases such as diabetes, hypertension, nephrotic syndrome, etc. have reduced nasal immunity, which significantly increases the risk of disease. Since early nasal symptoms are not obvious, multidisciplinary cooperation in diagnosis and treatment is very necessary. Once imaging examination suggests orbital apex syndrome caused by sinus lesions, endoscopic sinus opening should be performed as soon as possible.

Surface Structure Reformulation from CuO to Cu/Cu(OH)2 for Highly Efficient Nitrate Reduction to Ammonia.

Electrochemical conversion of nitrate (NO3 -) to ammonia (NH3) is a potential way to produce green NH3 and remediate the nitrogen cycle. In this paper, an efficient catalyst of spherical CuO made by stacking small particles with oxygen-rich vacancies is reported. The NH3 yield and Faraday efficiency are 15.53 mg h-1 mgcat -1 and 90.69%, respectively, in a neutral electrolyte at a voltage of -0.80 V (vs. reversible hydrogen electrode). The high activity of the electrodes results from changes in the phase and structure during electrochemical reduction. Structurally, there is a shift from a spherical structure with dense accumulation of small particles to a layered network structure with uniform distribution of small particles stacked on top of each other, thus exposing more active sites. Furthermore, in terms of phase, the electrode transitions from CuO to Cu/Cu(OH)2. Density functional theory calculations showed that Cu(OH)2 formation enhances NO3- adsorption. Meanwhile, the Cu(OH)2 can inhibit the competing hydrogen evolution reaction, while the formation of Cu (111) crystal surfaces facilitates the hydrogenation reaction. The synergistic effect between the two promotes the NO3- to NH3. Therefore, this study provides a new idea and direction for Cu-based oxides in electrocatalytic NH3 production.

Predicting habitat suitability for the soybean pod borer Leguminivora glycinivorella (Matsumura) using optimized MaxEnt models with multiple variables.

The soybean pod borer Leguminivora glycinivorella (Matsumura) is one of the most important soybean pests and often causes serious damage to Glycine max (L.) Merr., a leading source of dietary protein and oil in animal feed. However, the potential distribution patterns of this economically important pest and its driving factors require further investigation. Here, we used the optimized MaxEnt model to predict the potential distribution of this pest with multiple variables associated with climate, land use, and host plant, at its recorded range and a globe scale. Based on 4 variable combinations, the results show that the current suitable habitats of L. glycinivorella are primarily distributed in most of China, the Korean Peninsula, and Japan. Whereas no suitable area is present in other continents. In future projections, the suitable region shows a slight northward expansion compared with the result predicted with current climatic conditions, and the suitable areas of almost all future projections were stable in size. Among the 9 bioclimatic factors, BIO03 (isothermality) consistently highly contributes to the predictions, indicating that temperature may be a key factor influencing the habitat distribution of L. glycinivorella. Comparative analyses of projections further show that non-climatic factors are informative in the modeling as routinely used bioclimate variables. The spatio-temporal distribution patterns of suitable habitats and the regulatory factors predicted in this study could provide important guidance for L. glycinivorella management.

Clinical effect of botulinum toxin type A combined with autologous fat grafting in patients with nasolabial fold depression.

BACKGROUND: Nasolabial fold (NLF) depression can affect the facial appearance of patients to some extent and increase their psychological burdens. In recent years, autologous fat grafting (AFG) combined with botulinum toxin A (BTX-A) injection (AFG + BTX-A injection) has been gradually applied in the treatment of patients with NLF depression. Although studies have been conducted on the efficacy and safety of AFG + BTX-A injection in treating NLF depression, the experimental design, observational indicators, and sample enrollment criteria vary remarkably, making it difficult to draw convincing and consistent conclusions. Thus, further relevant research is warranted. AIM: To assess the esthetic improvement, efficacy, and safety of AFG + BTX-A injections in patients with NLF depression. METHODS: This study included 60 patients with NLF depression who were treated in our hospital from February 2019 to April 2021. These patients were categorized into control (n = 30) and observation (n = 30) groups. The observation group received AFG + BTX-A injection, whereas the control group underwent AFG only. All patients were evaluated using the wrinkle severity rating scale (WSRS) and global aesthetic improvement scale. The compactness of facial contours, skin evaluation indexes, adverse reactions, and satisfaction of the two groups were evaluated 3 months postoperatively. RESULTS: The WSRS scores of the observation group at 1, 3, and 6 months postoperatively were lower than those of the control group (P < 0.05). Three months postoperatively, facial fine lines and pores showed obvious improvement and the skin index score was higher in the observation group than in the control group (P < 0.05). The compactness of facial contours was better in the observation group than in the control group (P < 0.05). In addition, no remarkable differences were noted in the incidence of postoperative adverse reactions such as facial stiffness, facial asymmetry, facial bruising, and facial concavity inequality (P > 0.05). CONCLUSION: AFG + BTX-A injection is a highly safe, cost-effective, effective, and long-lasting treatment for NLF depression with high esthetic value, which should be promoted in the future.

Lymphovenous anastomosis and complex decongestive therapy for severe deformed lymphedema with recurrent infection: A case report.

BACKGROUND: Lower extremity lymphedema is a common complication following treatment for gynecological malignancies. Its incidence rate can reach up to 70%, affecting ~20 million people worldwide. However, specialized treatment centers are scarce, and there is a lack of consensus on treatment approaches. Furthermore, there are even fewer reports on the systematic and effective treatment of severe lymphedema with malformations. Effective management of this condition remains a significant challenge for clinicians. CASE SUMMARY: A 40-year-old woman developed bilateral leg swelling 6 years after receiving treatment for endometrial cancer. Since August 2018, she experienced > 30 episodes of lymphangitis. Upon presentation, she exhibited bilateral leg swelling and deformation, with four large swellings in the posterior thigh that impeded movement, and pain in the limbs. Skin manifestations included lichenoid lesions and features of deep sclerosis. Radionuclide lymphoscintigraphy confirmed the diagnosis of lower limb lymphedema. After 6 mo of complex decongestive therapy (CDT) and three lymphaticovenous anastomosis (LVA) treatments, the patient lost 49 kg in weight. She also experienced a maximum circumference reduction of 35.2 cm in the left lower limb and 37.5 cm in the right lower limb. The leg pain disappeared, her swelling significantly decreased, and she regained the ability to walk, cycle, and run normally. CONCLUSION: The combined application of CDT and LVA therapy demonstrates significant positive effects in the treatment of severe, deformed stage III lymphedema.

Trends in HIV Prevalence, Sexual Behavior, and Pre-Exposure Prophylaxis Willingness Among Transgender Women: An Analysis of Three Cross-Sectional Studies Conducted Mainly in Shenyang, China, 2014-2019.

Purpose: Although transgender women (TGW) bear the highest HIV burden worldwide, routine surveillance of this group is rare. We aimed to evaluate the trends in health characteristics of Chinese TGW. Methods: Three cross-sectional studies using snowball sampling were conducted in 2014, 2017, and 2019, primarily in Shenyang, China. A questionnaire and voluntary HIV testing were used to obtain information on background characteristics, sexual behaviors, pre-exposure prophylaxis (PrEP) willingness, and HIV status. Results: There were 220 respondents in 2014, 198 in 2017, and 247 in 2019 (average age 31.1±7.6 to 33.5±9.6 years). HIV prevalence significantly decreased from 29.5% (95% confidence interval [CI]: 25.3-38.4%) in 2014 to 19.4% (95% CI: 14.7-24.9%) in 2019 (p<0.05). The proportion of participants reporting condomless anal intercourse (CAI) with any partner fluctuated from 30.8% (95% CI: 25.1-36.1%) to 53.0% (95% CI: 45.8-60.1%). The proportion of participants willing to use PrEP decreased from 86.4% (95% CI: 81.1-90.6%) in 2014 to 62.8% (95% CI: 56.4-68.8%) in 2019. Factors significantly associated with HIV infection were CAI with any partner (multivariate odds ratio [ORm]: 3.58, 95% CI: 1.55-8.29 in 2017; ORm: 3.18, 95% CI: 1.56-6.46 in 2019) and PrEP willingness (ORm: 0.26, 95% CI: 0.12-0.58 in 2017). Conclusion: HIV prevalence and associated risk factors remain substantial among Chinese TGW. There is an urgent need to strengthen HIV surveillance in this population, and develop trans-friendly and effective interventions to minimize HIV prevalence and transmission.

Composition and influencing factors of hospitalization expenses for epilepsy patients based on path analysis.

OBJECTIVE: This study aimed to understand the composition and influencing factors of epilepsy patients' hospitalization expenses, thus providing a reference for reducing the disease burden of epilepsy patients in low- and middle-income developing countries. METHODS: A total of 4206 hospitalized cases of epilepsy from 2018 to 2020 were collected. Descriptive statistics were used to understand the patient cost composition, path analysis was used to understand the direct and indirect factors of hospitalization expenses. RESULTS: From 2018 to 2020, the average hospitalization expenses for epilepsy patients was 4,299.93 RMB yuan, and the average length of stay was 2.47 days. The highest proportion of hospitalization expenses was diagnosis costs (> 50%), followed by comprehensive medical service costs and drug costs. In terms of the total effect coefficient, the major factors affecting the hospitalization expenses were length of stay (0.880), emergency admission(0.463), and the comorbidities and complications(> 0.250). Hospital length of stay, discharge mode(death) and number of hospitalizations(2 times) affect hospitalization expenses through direct effect. Long-term hospitalization (> 30 days), admission routes(emergency), the comorbidities and complications, presence of drug allergy, and age also affect hospitalization expenses through indirect effects. CONCLUSION: Diagnosis costs and length of stay are important factors affecting the medical expenses of epilepsy inpatients. In general, the quality control of the hospital is good, but it still needs to standardize the diagnosis and treatment behavior of medical staff through the clinical path.

Transcriptomic decoding of regional cortical vulnerability to major depressive disorder.

Previous studies in small samples have identified inconsistent cortical abnormalities in major depressive disorder (MDD). Despite genetic influences on MDD and the brain, it is unclear how genetic risk for MDD is translated into spatially patterned cortical vulnerability. Here, we initially examined voxel-wise differences in cortical function and structure using the largest multi-modal MRI data from 1660 MDD patients and 1341 controls. Combined with the Allen Human Brain Atlas, we then adopted transcription-neuroimaging spatial correlation and the newly developed ensemble-based gene category enrichment analysis to identify gene categories with expression related to cortical changes in MDD. Results showed that patients had relatively circumscribed impairments in local functional properties and broadly distributed disruptions in global functional connectivity, consistently characterized by hyper-function in associative areas and hypo-function in primary regions. Moreover, the local functional alterations were correlated with genes enriched for biological functions related to MDD in general (e.g., endoplasmic reticulum stress, mitogen-activated protein kinase, histone acetylation, and DNA methylation); and the global functional connectivity changes were associated with not only MDD-general, but also brain-relevant genes (e.g., neuron, synapse, axon, glial cell, and neurotransmitters). Our findings may provide important insights into the transcriptomic signatures of regional cortical vulnerability to MDD.

Genotypic and phenotypic characterisation of three local chicken ecotypes of Ghana based on principal component analysis and body measurements.

This study aimed to characterise three Ghanaian local chicken ecotypes, namely, Interior Savannah, Forest, and Coastal Savannah, based on morphological data and single nucleotide polymorphism (SNP) genotypes. Morphological data including body weight, shank length, body girth, back length, thigh length, beak length, comb length, and wattle length were collected from 250 local chickens. DNA isolated from blood of 1,440 local chickens was used for SNP genotyping with the Affymetrix chicken 600k SNP chip. Principal component analysis showed that Forest and Coastal Savannah birds were closely related. Generally, all three ecotypes exhibited high genetic diversity, especially birds from the Interior Savannah zone. Morphological characterisation showed that ecotype (p = 0.016) and sex (p = 0.000) had significant effects on body weight. Birds of the Interior Savannah ecotype were the heaviest (p = 0.004), with mean weights of 1.23 kg for females and 1.40 kg for males. Sex also had a strong significant effect on most of the morphological measurements, but the sex * ecotype interaction effect was not significant. Very few of the feather phenotypes previously reported to be associated with heat resistance-frizzle (2%) and naked neck (1.6%)-were found in the studied populations. It is concluded that the three local ecotypes are genetically diverse but with similar morphological features and the information provided would be useful for future selection decisions.

Growth inhibition of pancreatic cancer by targeted delivery of gemcitabine via fucoidan-coated pH-sensitive liposomes.

Fucoidan-coated pH sensitive liposomes were designed for targeted delivery of gemcitabine (FU-GEM PSL) to treat pancreatic cancer (PC). FU-GEM PSL had a particle size of 175.3 ± 4.9 nm, zeta potential of -19.0 ± 3.7 mV, encapsulation efficiency (EE) of 74.05 ± 0.17 %, and drug loading (DL) of 21.27 ± 0.05 %. Cell experiments in vitro showed that FU-GEM PSL could increase the release of GEM and drug concentration, and could inhibit tumor cell proliferation by affecting the cell cycle. FU-GEM PSL entered cells through macropinocytosis and caveolin-mediated endocytosis to exert effects. Meanwhile, the expression of P-selectin was detected in human tissues, demonstrating the feasibility of targeting FU. Moreover, combined with animal experiments in vivo, FU-GEM PSL could inhibit the development of PC. Furthermore, anti-tumor experiments in vivo carried on BALB/c mice indicated that FU-GEM PSL had tumor suppression abilities and safety. Therefore, FU-GEM PSL is a promising formulation for PC therapy.

Lipid homeostasis in diabetic kidney disease.

Lipid homeostasis is crucial for proper cellular and systemic functions. A growing number of studies confirm the importance of lipid homeostasis in diabetic kidney disease (DKD). Lipotoxicity caused by imbalance in renal lipid homeostasis can further exasperate renal injury. Large lipid deposits and lipid droplet accumulation are present in the kidneys of DKD patients. Autophagy plays a critical role in DKD lipid homeostasis and is involved in the regulation of lipid content. Inhibition or reduction of autophagy can lead to lipid accumulation, which in turn further affects autophagy. Lipophagy selectively recognizes and degrades lipids and helps to regulate cellular lipid metabolism and maintain intracellular lipid homeostasis. Therefore, we provide a systematic review of fatty acid, cholesterol, and sphingolipid metabolism, and discuss the responses of different renal intrinsic cells to imbalances in lipid homeostasis. Finally, we discuss the mechanism by which autophagy, especially lipophagy, maintains lipid homeostasis to support the development of new DKD drugs targeting lipid homeostasis.

Interdependent stigma of seeking mental health services: Examining a new scale across eight countries/regions.

Although the presence of mental health stigma associated with seeking help has been demonstrated in many parts of the world, this work has largely been from an independent perspective (i.e., "I will be perceived as crazy") rather than from an interdependent perspective (i.e., "My family will be viewed negatively"). Interdependent stigma of seeking help (i.e., the extent to which people believe their family would be devalued and shamed if they seek psychological help) may be an important type of stigma that has not been assessed. Based on self-construal theory, the present study sought to develop and evaluate the psychometric properties of an Interdependent Stigma of Seeking Help (ISSH) scale in eight different countries and regions (i.e., Australia, Brazil, Germany, Hong Kong, Taiwan, Türkiye, the UAE, the United States). Findings suggest that the psychometric properties of the eight-item ISSH are adequate for research purposes (a unidimensional scale with full invariance and internal consistency estimates from .84 to .94). The ISSH was moderately related to other measures of stigma and psychological distress. Some differences in the relationship with specific outcomes by country and region were found, and there were notable country differences in the latent mean levels of ISSH, with Hong Kong and Taiwan having the highest means, and Australia, the United States, and Brazil having the lowest levels. Results suggest that the ISSH could be used to help clarify the complex relationships between stigma and other variables of interest and might be useful in developing culturally relevant interventions.

Revisiting the effects of rTMS over the dorsolateral prefrontal cortex on pain: An updated systematic review and meta-analysis.

BACKGROUND: Our previous study synthesized the analgesic effects of repetitive Transcranial Magnetic Stimulation (rTMS) over the dorsolateral prefrontal cortex (DLPFC) trials up to 2019. There has been a significant increase in pain trials in the past few years, along with methodological variabilities such as sample size, stimulation intensity, and rTMS paradigms. OBJECTIVES/METHODS: This study therefore updated the effects of DLPFC-rTMS on chronic pain and quantified the impact of methodological differences across studies. RESULTS: A total of 36 studies were included. Among them, 26 studies were clinical trials (update = 9, 307/711 patients), and 10 (update = 1, 34/249 participants) were provoked pain studies. The updated meta-analysis does not support an effect on neuropathic pain after including the additional trials (pshort-term = 0.20, pmid-term = 0.50). However, there is medium-to-large analgesic effect in migraine trials extending up to six weeks follow-up (SMDmid-term = -0.80, SMDlong-term = -0.51), that was not previously reported. Methodological differences wthine the studies were considered. DLPFC-rTMS also induces potential improvement in the emotional aspects of pain (SMDshort-term = -0.28). CONCLUSIONS: The updated systematic meta-analysis continues to support analgesic effects for chronic pain overall. However, the updated results no longer support DLPFC-rTMS for pain relief in neuropathic pain, and do supports DLPFC-rTMS in the management of migraine. There is also evidence for DLPFC-rTMS to improve emotional aspects of pain.

Causal factors of cardiovascular disease in end-stage renal disease with maintenance hemodialysis: a longitudinal and Mendelian randomization study.

Background: The risk factors of cardiovascular disease (CVD) in end-stage renal disease (ESRD) with hemodialysis remain not fully understood. In this study, we developed and validated a clinical-longitudinal model for predicting CVD in patients with hemodialysis, and employed Mendelian randomization to evaluate the causal 6study included 468 hemodialysis patients, and biochemical parameters were evaluated every three months. A generalized linear mixed (GLM) predictive model was applied to longitudinal clinical data. Calibration curves and area under the receiver operating characteristic curves (AUCs) were used to evaluate the performance of the model. Kaplan-Meier curves were applied to verify the effect of selected risk factors on the probability of CVD. Genome-wide association study (GWAS) data for CVD (n = 218,792,101,866 cases), end-stage renal disease (ESRD, n = 16,405, 326 cases), diabetes (n = 202,046, 9,889 cases), creatinine (n = 7,810), and uric acid (UA, n = 109,029) were obtained from the large-open GWAS project. The inverse-variance weighted MR was used as the main analysis to estimate the causal associations, and several sensitivity analyses were performed to assess pleiotropy and exclude variants with potential pleiotropic effects. Results: The AUCs of the GLM model was 0.93 (with accuracy rates of 93.9% and 93.1% for the training set and validation set, sensitivity of 0.95 and 0.94, specificity of 0.87 and 0.86). The final clinical-longitudinal model consisted of 5 risk factors, including age, diabetes, ipth, creatinine, and UA. Furthermore, the predicted CVD response also allowed for significant (p < 0.05) discrimination between the Kaplan-Meier curves of each age, diabetes, ipth, and creatinine subclassification. MR analysis indicated that diabetes had a causal role in risk of CVD (ß = 0.088, p < 0.0001) and ESRD (ß = 0.26, p = 0.007). In turn, ESRD was found to have a causal role in risk of diabetes (ß = 0.027, p = 0.013). Additionally, creatinine exhibited a causal role in the risk of ESRD (ß = 4.42, p = 0.01). Conclusions: The results showed that old age, diabetes, and low level of ipth, creatinine, and UA were important risk factors for CVD in hemodialysis patients, and diabetes played an important bridging role in the link between ESRD and CVD.
