Background: Obesity and chronic pain are related in both directions, according to earlier observational research.This research aimed to analyze the causal association between obesity and chronic pain at the genetic level, as well as to assess whether common factors mediate this relationship. Methods: This study used bidirectional two sample Mendelian randomization (MR) technique to analyze the association between obesity and chronic pain. Obesity's summary genome-wide association data were obtained from European ancestry groups, as measured by body mass index (BMI), waist-to-hip ratio, waist circumference (WC), and hip circumference (HC), genome-wide association study data for chronic pain also came from the UK population, including chronic pain at three different sites (back, hip, and headache), chronic widespread pain (CWP), and multisite chronic pain (MCP). Secondly, a two-step MR and multivariate MR investigation was performed to evaluate the mediating effects of several proposed confounders. Results: The authors discovered a link between chronic pain and obesity. More specifically, a sensitivity analysis was done to confirm the associations between greater BMI, WC, and HC with an increased risk of CWP and MCP.Importantly, the intermediate MR results suggest that education levels and smoking initiation may mediate the causal relationship between BMI on CWP, with a mediation effect of 23.08% and 15.38%, respectively. Conclusions The authors’ findings demonstrate that the importance of education and smoking in understanding chronic pain’s pathogenesis, which is important for the primary prevention and prognosis of chronic pain.

Objective To investigate gender differences and age-related changes in body composition(BC)among Miao adults in Rongshui,Guangxi Province,and to provide the basis for assessing nutritional status and health.Methods With informed consent,630 Miao adults(218 males,412 females)were randomly selected for this study.Body composition was assessed using bioelectrical impedance analysis(BIA).Results Weight,fat-free mass,muscle mass,trunk muscle mass,limb muscle mass,waist-to-hip ratio(WHR),body water,presumtion of bone mass and protein were significantly higher in males than in females.And the fat mass,trunk fat mass,limb fat mass,visceral fat content,subcutaneous fat content and percentage of body fat were significantly higher in females than in males.According to the evaluation of body mass index(BMI)and WHR,the proportion of overweight and obesity of Miao adults was higher than the average level of Miao residents,and their obesity was characterized by central obesity.With age,weight,fat mass,muscle mass,fat-free mass,limb muscle mass,limb fat mass,subcutaneous fat content,percentage of body fat,body water,presumtion of bone mass,and protein of Rongshui Miao adults showed a gradual decreasing trend,while visceral fat content and WHR increased progressively.BMI in male Miao adults,along with BMI,fat mass,trunk fat mass,subcutaneous fat content,percentage of body fat,and body water in female Miao adults,showed a trend of increasing followed by decreasing,peaking at the age of 40-49 years.Conclusion The body composition of Miao adults in Rongshui,Guangxi,exhibits significant gender differences and age-related variation change patterns,which may increase the risk of sarcopenia and metabolic diseases with aging.

Objective To explore and analyze the expression and prognostic value of serum vitamin D(VitD),fer-ritin(FRT)and heparin-binding epidermal growth factor(HB-EGF)in sepsis patients.Methods 86 sepsis patients who were admitted to the intensive care unit(ICU)of a hospital from January 2021 to January 2022 were selected as the case group,and 60 non-sepsis patients in the ICU were selected as the control group.According to the prognosis of sepsis patients one month later,patients were divided into survival group and death group.Patient's serum upon admission was taken,levels of serum VitD,FRT and HB-EGF were detected,the correlation with the prognosis of sepsis patients was analyzed,and the prognostic value was evaluated by area under curve(AUC)of receiver opera-ting characteristic curve.Results Levels of white blood cell count(WBC),C-reactive protein(CRP),procalcitonin(PCT),tumor necrosis factor-α(TNF-α),interleukin(IL)-6,IL-1β and FRT of case group were all higher than those of non-sepsis patients in the control group,while the VitD and HB-EGF levels were lower than those of non-sepsis patients in the control group,differences were all statistically significant(all P＜0.05).One month follow-up on the prognosis of sepsis patients showed that 55 patients survived and 31 died.Acute physiology and chronic health evaluationⅡ(APACHE IⅡ)score,sequential organ failure assessment(SOFA)score,PCT,TNF-α,L-1βand FRT score in patients in the death group were all higher than those in patients in the survival group,while VitD and HB-EGF were lower than patients in the survival group,differences were all statistically significant(all P＜0.05).The Pearson correlation analysis results showed that VitD were negatively correlated with APACHE Ⅱ score,SOFA score,WBC,CRP,PCT and TNF-α(all P＜0.05),HB-EGF was negatively correlected with APACHE Ⅱ,score,CRP,PCT,TNF-α,IL-6 and IL-1β(all P＜0.05);while FRT was positively correlated with APACHE Ⅱscores,CRP,PCT,TNF-α,IL-6 and IL-1β(all P＜0.05).The AUC,sensitivity,and specificity of combined de-tection of serum VitD,FRT and HB-EGF in predicting the prognosis of sepsis patients were 0.82(95％CI:0.72-0.86),84.39％,and 69.35％,respectively.Conclusion Serum levels of VitD and HB-EGF are lower and FRT is higher in sepsis patients,their expression levels are closely related to patient prognosis,and have good predictive value for predicting the prognosis of sepsis patients.

Obstructive sleep apnea hypopnea syndrome (OSAHS) is a sleep breathing disorder caused by obstruction of the upper airway during sleep from various causes. At present, the diagnosis and treatment of OSAHS are insufficient. OSAHS causes cognitive decline due to excessive oxidative stress and inflammatory response caused by sleep breathing disorder, and its alteration of the brain gray matter area may be related to cognitive dysfunction. This review investigates the correlation between cognitive dysfunction and brain gray matter areas changes in OSAHS, and elucidates the underlying mechanisms, which provide a theoretical basis for early clinical diagnosis and treatment.

BACKGROUND: Reports on the prevalence of psoriatic arthritis (PsA) among Chinese patients with psoriasis are very limited. This study, conducted by rheumatologists, estimated the prevalence of PsA in a large number of Chinese patients with psoriasis. METHODS: Consecutive patients with a confirmed diagnosis of psoriasis attending nine dermatology clinics in five hospitals were recruited. All psoriasis patients were asked to complete a questionnaire comprising 16 questions to identify possible cases of PsA. All patients with one or more positive answers to the questionnaire were evaluated by two experienced rheumatologists. RESULTS: A total of 2434 psoriasis patients, including 1561 males and 873 females, were enrolled. Both the questionnaire and rheumatologists' examinations were completed in the dermatology clinics. The results identified 252 patients with PsA, comprising 168 males and 84 females. The overall prevalence of PsA among psoriasis patients was 10.4% (95% confidence interval [95% CI], 9.1%-11.7%). By sex, the prevalence was 10.8% (95% CI, 9.2%-12.5%) for males and 9.6% (95% CI, 7.7%-11.9%) for females and there was no significant sex difference in the prevalence of PsA (P = 0.38). Of the 252 PsA patients, 125 (49.6%, 95% CI, 41.3%-59.1%) were newly diagnosed by rheumatologists. Consequently, the prevalence of undiagnosed PsA among psoriasis patients was 5.2% (95% CI, 4.4%-6.2%). CONCLUSION The prevalence of PsA in the Chinese population with psoriasis is about 10.4%, which is almost double that of previous reports in the Chinese population, but lower than that in Caucasians.
