BACKGROUND: Spicy food consumption has been reported to be inversely associated with mortality from multiple diseases. However, the effect of spicy food intake on the incidence of vascular diseases in the Chinese population remains unclear. This study was conducted to explore this association. METHODS: This study was performed using the large-scale China Kadoorie Biobank (CKB) prospective cohort of 486,335 participants. The primary outcomes were vascular disease, ischemic heart disease (IHD), major coronary events (MCEs), cerebrovascular disease, stroke, and non-stroke cerebrovascular disease. A Cox proportional hazards regression model was used to assess the association between spicy food consumption and incident vascular diseases. Subgroup analysis was also performed to evaluate the heterogeneity of the association between spicy food consumption and the risk of vascular disease stratified by several basic characteristics. In addition, the joint effects of spicy food consumption and the healthy lifestyle score on the risk of vascular disease were also evaluated, and sensitivity analyses were performed to assess the reliability of the association results. RESULTS: During a median follow-up time of 12.1 years, a total of 136,125 patients with vascular disease, 46,689 patients with IHD, 10,097 patients with MCEs, 80,114 patients with cerebrovascular disease, 56,726 patients with stroke, and 40,098 patients with non-stroke cerebrovascular disease were identified. Participants who consumed spicy food 1-2 days/week (hazard ratio [HR] = 0.95, 95% confidence interval [95% CI] = [0.93, 0.97], P <0.001), 3-5 days/week (HR = 0.96, 95% CI = [0.94, 0.99], P = 0.003), and 6-7 days/week (HR = 0.97, 95% CI = [0.95, 0.99], P = 0.002) had a significantly lower risk of vascular disease than those who consumed spicy food less than once a week ( Ptrend <0.001), especially in those who were younger and living in rural areas. Notably, the disease-based subgroup analysis indicated that the inverse associations remained in IHD ( Ptrend = 0.011) and MCEs ( Ptrend = 0.002) risk. Intriguingly, there was an interaction effect between spicy food consumption and the healthy lifestyle score on the risk of IHD ( Pinteraction = 0.037). CONCLUSIONS Our findings support an inverse association between spicy food consumption and vascular disease in the Chinese population, which may provide additional dietary guidance for the prevention of vascular diseases.

Objective To investigate the auditory effects of cochlear implantation in quiet and noisy environ-ments in children with different bilateral intervention modes,as well as the factors influencing these effects.Methods A total of 185 children with bilateral severe to profound sensorineural hearing loss were divided into three groups:bimodal hearing mode group(BIM,n=55),simultaneous bilateral cochlear implantation group(SCI,n=70),and sequential bilateral cochlear implantation group(SBCI,n=60).The Parents' Evaluation of Aural/Oral Performance of Children(PEACH)was used to assess the PEACH scores of the three groups in quiet and noisy environments one year after binaural hearing aid intervention.Additionally,the effects of cochlear implantation age,preoperative residual hearing,hearing aid usage,rehabilitation training mode,family system,and other factors on auditory per-formance in quiet and noisy environments were analyzed.Results The PEACH scores in quiet environments were higher than those in noisy environments for all three groups(all P＜0.05).The SCI group had higher PEACH scores in both quiet and noisy environments compared to the BIM group(P＜0.05).Multifactorial analysis revealed differences in factors influencing auditory performance in quiet and noisy environments among the three groups.First cochlear implantation before 3 years of age,preoperative hearing aid usage,and home-based rehabilitation training mode were common favourable influencing factors for auditory performance in both environments.Preopera-tive residual hearing below 95 dB HL was an favourable influencing factor for auditory performance in quiet environ-ments in the BIM group.The higher the level of parental education,the better auditory performance in both quiet and noisy environments for the SCI and SBCI groups.Implantation interval of 24 months or less and hearing aid usage during the inter-implantation period were favourable influencing factors for auditory performance in both envi-ronments for the SBCI group.Conclusion Children with severe to profound prelingual deafness after simultaneous bilateral CI implantation had better hearing performance than bimodal listening in quiet and noise environments.Ear-ly implantation,preoperative or inter-implantation hearing aid usage are recommended to improve auditory perform-ance in noisy environments,regardless of the bilateral intervention mode.The interval between bilateral cochlear im-plantations should be less than 12 months.

Objective:To investigate the association between sleep status and the risk for coronary heart disease in adults in Suzhou.Methods:Using the baseline and follow up information of 53 269 local residents aged 30-79 years in China Kadoorie Biobank conducted in Wuzhong District, Suzhou, 51 929 subjects were included in this study after excluding those reporting coronary heart disease, stroke and cancer at the baseline survey. A Cox proportional hazards regression model was used to analyze the association of healthy sleep score (0-3 points) and sleep factors (snoring, insomnia, long sleep duration and nap) with the risk for coronary heart disease.Results:The median follow-up time was 11.12 years, and 1 304 individuals were diagnosed with coronary heart disease during the follow-up. After adjusting for potential confounders, occasional snoring ( HR=1.20, 95% CI: 1.04-1.38), usual snoring ( HR=1.17, 95% CI: 1.02-1.33), insomnia disorder ( HR=1.41, 95% CI: 1.12-1.78), daytime dysfunction ( HR=1.56, 95% CI: 1.20-2.03) and perennial nap ( HR=1.37, 95% CI: 1.19-1.59) were associated with increased risk of coronary heart disease. Compared with those with sleep score of 0 - 1 (low sleep quality), the people with sleep score of 3 had reduced risk of coronary heart disease by 26% ( HR=0.74, 95% CI: 0.63-0.87). Stratified analysis showed that the association of healthy sleep score 3 with risk of coronary heart disease was stronger in low physically active individuals (interaction P<0.05). Conclusions:Snoring, insomnia disorders, daytime dysfunction, and perennial napping were all associated with increased risk for coronary heart disease, and keep healthy sleep mode might reduce the risk for coronary heart disease in adults.

Objective:To study the clinical characteristics and prognosis of Brucella and other pathogens infections complicated with anti-myelin oligodendrocyte glycoprotein-IgG associated disorders (MOGAD). Methods:The clinical data of a patient with brucellosis complicated with MOGAD diagnosed in the Department of Neurology of the First Affiliated Hospital of Zhengzhou University in April 2022 were reported, and related case reports of infection coexisting with MOGAD were reviewed and summarized.Results:This case was a 44-year-old male, with recurrent fever and anorexia, followed by sudden weakness, numbness, pain in both lower limbs and dysuria, and then pain in the right neck. Magnetic resonance imaging showed lesions in the spine and spinal cord. Due to the positive myelin oligodendrocyte glycoprotein antibodies in cerebrospinal fluid and serum, and the growth of Brucella in blood culture, he was diagnosed as brucellosis complicated with MOGAD. After anti-brucellosis and glucocorticoid therapy, his symptoms improved. The literature on infection coexisting with MOGAD was reviewed and 22 cases were included. The infection sources included COVID-19, Borrelia burgdorferi, etc. No case of Brucella infection complicated with MOGAD had been reported. The main clinical manifestations of the 22 cases included myelitis (63.6%, 14/22), optic neuritis (40.9%, 9/22), acute disseminated encephalomyelitis (18.2%, 4/22), multiphasic disseminated encephalomyelitis (4.5%, 1/22) and meningoencephalitis (4.5%, 1/22). Magnetic resonance imaging was performed in 20 cases, showing spinal cord lesions in 12 cases (60.0%, 12/20), intracranial lesions in 10 cases (50.0%, 10/20) and optic nerve lesions in 6 cases (30.0%, 6/20). Cerebrospinal fluid examination was performed in 19 patients, of whom 13 (13/19) had increased cerebrospinal fluid cell count and 10 (10/18) had increased cerebrospinal fluid protein. Twenty-two patients received glucocorticoid therapy, of which 95.5% (21/22) responded well and 95.5% (21/22) had a good prognosis. Conclusions:Brucella and other pathogens infection may complicate with MOGAD, with similar clinical manifestations, and glucocorticoid therapy is effective.

Objective::Microchannels are associated with the progression of atherosclerotic vulnerable plaques. However, in patients with culprit optical coherence tomography (OCT)-defined plaque erosion, the knowledge of microchannels and culprit lesion vulnerability is limited. The aim of this study was to investigate culprit lesion characteristics in patients with ST-segment elevated myocardial infarction (STEMI) caused by plaque erosion with and without microchannels using OCT.Methods::In all, 348 STEMI patients with plaque erosion who underwent OCT of the culprit lesion at the 2 nd Affiliated Hospital of Harbin Medical University (Harbin, China) from August 2014 to December 2017 were included and divided into the microchannel group ( n= 116, 33.3%) and no-microchannel group ( n = 232, 66.7%). The clinical characteristics and OCT-derived plaque features were compared between both groups. Results::Among the 348 STEMI patients with plaque erosion, culprit lesions with microchannels had higher incidence of lipid plaque (59.5% vs. 45.3%, P= 0.012); calcification (41.4% vs. 24.6%, P= 0.002); spotty calcification (30.2% vs. 18.1%, P= 0.014); macrophages accumulation (72.4% vs. 45.7%, P < 0.001); and cholesterol crystals (32.8% vs. 14.2%, P < 0.001) than those without microchannels. In addition, minimal lumen area was smaller ((1.9 ± 0.9) mm 2vs. (2.8 ± 2.3) mm 2, P < 0.001) and lumen area stenosis was greater ((71.3% ± 13.4%) vs. (65.3% ± 19.3%), P= 0.001) in the microchannel group than in the no-microchannel group. Conclusion::In patients with STEMI caused by plaque erosion, one-third manifested typical microchannel characteristics, and those with microchannels were associated with more severe luminal stenosis and more vulnerable plaque features than those without microchannels.
