Effect of mean platelet volume and platelet count on the prognosis of branch atheromatous disease.

OBJECTIVE: The purpose of this study was to investigate the predictive value of mean platelet volume (MPV) and platelet count (PC) in branch atheromatous disease (BAD). METHODS: This retrospective study included 216 patients with BAD-stroke within 48 h of symptom onset. These patients were divided into good and poor prognosis groups according to their 3-month modified Rankin scale scores after discharge. Multiple logistic regression analysis was used to evaluate independent predictors of poor prognosis in BAD-stroke patients. Receiver-operating characteristic (ROC) analysis was used to estimate the predictive value of MPV and PC on BAD-stroke. RESULTS: Our research showed that a higher MPV (aOR, 2.926; 95% CI, 2.040-4.196; p < .001) and PC (aOR, 1.013; 95% CI, 1.005-1.020; p = .001) were independently associated with poor prognosis after adjustment for confounders. The ROC analysis of MPV for predicting poor prognosis showed that the sensitivity and specificity were 74% and 84.9%, respectively, and that the AUC was .843 (95% CI, .776-.909, p < .001). The optimal cut-off value was 12.35. The incidence of early neurological deterioration (END) was 24.5% (53 of 163), and 66% of patients in the poor prognosis group had END (33 of 50). Multiple logistic regression analyses showed that elevated MPV and PC were associated with the occurrence of END (p < .05). CONCLUSION: Our results suggested that an elevated MPV and PC may be important in predicting a worse outcome in BAD-stroke patients. Our study also demonstrated an independent association of MPV and PC with END, which is presumably the main reason for the poor prognosis.

A Systematic Review and Meta-Analysis of the Predictive Power of China-PAR Against Cardiovascular Disease.

Background and Purpose: To evaluate the predictive power of the China-PAR model for cardiovascular disease (CVD).Methods: Dominate databases, including PubMed, Web of Science, CNKI, Wanfang Data Knowledge Service Platform, Chinese Biomedical Literature Service System, and VIP self-built database, were searched from January 1, 2016 to February 22, 2022. The primary outcome included observed events and predicted events by China-PAR. Meta-analysis was performed using RevMan 5.3 software. Stroke, arteriosclerotic cardiovascular disease (ASCVD), male, and female were divided into subgroup analyses. Funnel plots were used to assess publication bias.Results: A total of nine studies, which included 221,918 participants, were analyzed. Meta-analysis showed the combined observed incidence of CVD was 3.97%, and the combined predicted incidence was 9.59% by China-PAR. There was no significant difference between the observed and the predicted events. Subgroup analysis showed there was no statistical significance between the observed and the predicted events for stroke or for ASCVD. The difference between the observed and the predicted events by China-PAR was not statistically significant in either males or females.Conclusions: China-PAR model has important public health significance to further improve the primary prevention strategy of CVD.

Transverse spinal cord infarction following immunoglobulin treatment in a patient with exfoliative dermatitis: A case report.

RATIONALE: Transverse spinal cord infarction (SCI) is rare but highly disabling. Aortic thrombosis was described as one of the most common etiologies. Thromboembolic complications associated with intravenous immunoglobulin (IVIG) have been reported. PATIENT CONCERNS: A previously well, 64-year-old man who was given the treatment of IVIG (0.4 g/kg/d for 5 days) for exfoliative dermatitis 2 weeks before, progressively developed flaccid paraplegia of lower extremities, loss of all sensations below T3 level and urinary incontinence within 50 minutes. DIAGNOSES: A diagnosis of SCI and pulmonary embolism was made. IVIG was considered the possible cause. INTERVENTIONS: Anticoagulation treatment and continuous rehabilitation were administered. OUTCOMES: The neurologic deficiency of the patient was partially improved at the 3-year follow-up. LESSONS: The rapid development of severe deficits within 4 hours mostly contributes to the diagnosis of SCI. Heightened awareness of possible thrombotic events is encouraged for a month-long period following IVIG therapy.

Predictive factors for early neurological deterioration after intravenous thrombolysis of single subcortical infarction in the territory of the middle cerebral artery.

INTRODUCTION: Patients with a single subcortical infarction (SSI) in the territory of the middle cerebral artery (MCA) often experience early neurological deterioration (END) despite receiving intravenous thrombolytic therapy (IVT). In this study, predictors of END were investigated in patients with SSI in the MCA after IVT. METHODS: Patients with SSI in the MCA territory who had received IVT between June 2020 and 2022 were included. END was defined as an increase in the total National Institutes of Health Stroke Scale (NIHSS) score by ≥2 or in the motor NIHSS score by ≥1 within the first 72 h of admission. Patients with proximal (pSSI) and distal SSI (dSSI) were analyzed to determine SSI type-specific predictors for END. RESULTS: We evaluated 174 patients with SSI in the MCA territory who underwent IVT. Multivariable logistic regression analysis showed that pSSI (odds ratio [OR] = 0.242; 95% confidence interval [CI], 0.104-0.564; p = .001), lower high-density lipoprotein cholesterol (HDL-C) (OR = 0.150; 95% CI, 0.033-0.682; p = .014), higher blood glucose (OR = 0.858; 95% CI, 0.752-0.979; p = .023), and higher red blood cells count (OR = 1.966; 95% CI, 1.154-3.349; p = .013) were risk factors for END. In patients with pSSI, HDL-C and blood glucose were associated with END. No variable related to END was found in the dSSI group. CONCLUSIONS: The proportion of END in patients with SSI in the MCA territory after IVT was not low; therefore, pSSI, HDL-C, blood glucose, and red blood cells should be monitored closely. The frequency and predictors of SSI in the MCA territory differed between pSSI and dSSI.

Depression status and functional outcome of patients with ischemic stroke and the impact on caregivers living in Chengdu: a cross-sectional study.

Objectives: To investigate the associations between risk factors and depression symptoms in ischemic stroke (IS) survivors and the effect of IS survivors' depression status and functional outcomes on caregiver burden in Chengdu, China. Methods: In this cross-sectional study, we recruited a convenience sample of patients with IS and paired caregivers living in Chengdu from February 2022 to May 2022. Depression symptoms were assessed using the 17-item Chinese Hamilton Depression Rating Scale, the social support of patients was assessed using the perceived social support scale (PSSS), caregiver burden was assessed using the Zarit burden interview (ZBI). Multivariable logistic regression analysis was used to analyze the data between risk factors and depression symptoms, and multiple linear regression models were constructed to examine the depression symptoms and functional outcomes of stroke survivors, and caregiver burden. Results: In total, 966 IS survivors and paired caregivers were included in this study. Among IS survivors, 35.51% (343/966) experienced depression. Age [adjusted odds ratio (aOR), 1.02; 95% confidence interval (CI), 1.00-1.04; p = 0.036], the National Institutes of Health Stroke Scale (NIHSS) score (aOR, 1.57; 95% CI, 1.47-1.68; p < 0.001), and PSSS score (aOR, 0.86; 95% CI, 0.84-0.89; p < 0.001) were associated with an increased risk of depression. The NIHSS score (b = 2.57, p < 0.001), patients' depression status (b = 2.54, p < 0.001), duration of care (b = 0.359, p = 0.006), and social support of caregivers (b = -0.894, p = 0.038) were significantly associated with the ZBI score. Conclusion: The PSSS score was a major risk factor for the development of depression in IS survivors, and patients' depression status and severe functional deficits had a negative impact on the ZBI score of the main caregivers. Social support can reduce the ZBI score.

The current state of artificial intelligence in endoscopic diagnosis of early esophageal squamous cell carcinoma.

Esophageal squamous cell carcinoma (ESCC) is a common malignant tumor of the digestive tract. The most effective method of reducing the disease burden in areas with a high incidence of esophageal cancer is to prevent the disease from developing into invasive cancer through screening. Endoscopic screening is key for the early diagnosis and treatment of ESCC. However, due to the uneven professional level of endoscopists, there are still many missed cases because of failure to recognize lesions. In recent years, along with remarkable progress in medical imaging and video evaluation technology based on deep machine learning, the development of artificial intelligence (AI) is expected to provide new auxiliary methods of endoscopic diagnosis and the treatment of early ESCC. The convolution neural network (CNN) in the deep learning model extracts the key features of the input image data using continuous convolution layers and then classifies images through full-layer connections. The CNN is widely used in medical image classification, and greatly improves the accuracy of endoscopic image classification. This review focuses on the AI-assisted diagnosis of early ESCC and prediction of early ESCC invasion depth under multiple imaging modalities. The excellent image recognition ability of AI is suitable for the detection and diagnosis of ESCC and can reduce missed diagnoses and help endoscopists better complete endoscopic examinations. However, the selective bias used in the training dataset of the AI system affects its general utility.

A descriptive study on clinical department managers' cognition of the Plan-Do-Check-Act cycle and factors influencing their cognition.

BACKGROUND: The mastery and application of the "Plan-Do-Check-Act" (PDCA) cycle by hospital clinical department managers are essential for hospitals to carry out total quality management and continuously improve medical quality. This study investigated the degree of cognition of the PDCA cycle by clinical department managers and the factors affecting their cognition. METHODS: A self-designed questionnaire was used to evaluate the cognition of clinical department managers regarding the PDCA cycle in 11 municipal public Class III Grade A hospitals in Western China. RESULTS: More than 25% of clinical department managers in the surveyed hospitals are unaware or partially aware of the PDCA cycle. Logistic regression analysis showed that sex (P = 0.049), education (P < 0.001), duty (P < 0.001), and tenure (P = 0.002) had a significant influence on managers' cognition of PDCA. Participants who were female (P < 0.001), undergraduate (P < 0.001), head nurses, or deputy head nurses (P < 0.001), with a tenure of 5-10 years (P = 0.024) had a better cognition of the PDCA cycle. In the daily management of the department, the vast majority of managers do not implement the Check and Action steps. Among the trained managers, only 65.44% applied the complete PDCA cycle in daily management. Nearly a third of managers thought PDCA was a response to hospital demands; 82.83% of the managers need to receive PDCA cycle training, and half of them indicated a preference for online training. CONCLUSIONS: The cognition level of hospital clinical department managers regarding the PDCA cycle is relatively low, especially among the clinical department heads, and most of them are willing to accept PDCA cycle training.

Serum uric acid to serum creatinine ratio predicts neurological deterioration in branch atheromatous disease.

Background and objective: Branch atheromatous disease (BAD) makes patients prone to early neurological deterioration (END), resulting in poor prognosis. The aim of this study was to investigate the association between SUA/SCr and END in BAD stroke patients. Methods: We conducted a retrospective study that included 241 patients with BAD-stroke within 48 h of symptom onset. We divided the patients into the END group and the no END group. END was defined as an NIHSS score increase of more than 2 points within 1 week. SUA/SCr was calculated by the concentration of serum uric acid and creatine (serum uric acid/serum creatine) on admission. Univariate and multivariate analyses were used to identify independent predictors of END in BAD-stroke patients. Results: END was observed in 24.1% (58/241) of the patients in our study. Multiple logistic regression analyses showed that SUA/SCr (aOR, 0.716; 95% CI, 0.538-0.952; P = 0.022) and female sex (aOR, 0.469; 95% CI, 0.245-0.898; P = 0.022) were associated with END after adjusting for confounding factors. The predicted value of SUA/Scr for END was a sensitivity of 79.3%, a specificity of 44.8%, and an AUC of 0.609 (95% CI, 0.527-0.691, P < 0.05). The optimal cut-off value was 4.76. Conclusion: SUA/SCr was negatively associated with the risk of END in BAD stroke patients.

Endothelial function and arterial stiffness indexes in subjects with carotid plaque and carotid plaque length: A subgroup analysis showing the relationship with hypertension and diabetes.

BACKGROUND: Stroke is a leading cause of death and disability globally. A large proportion of ischemic strokes are caused by carotid atherosclerotic plaques. However, the relationship between vascular health status (arterial stiffness and endothelial dysfunction) and carotid plaque remains unclear. OUR STRATEGY: Here, we recruited 991 subjects with carotid plaques and 1170 subjects without carotid plaques to measure arterial stiffness and endothelial dysfunction, using a logistic regression model and multiple linear regression models to predict the relationship between them and carotid plaques. MAIN RESULTS: The data revealed that patients with carotid plaques presented a significantly higher mean of cf-PWV and lower mean RHI values. Age, male gender, diabetes, hypertension, and smoking contributed to plaque formation. Carotid plaques and their lengths were negatively associated with RHI values and positively associated with cf-PWV values; diabetes combined with hypertension showed a cumulative effect on arteriosclerosis. CONCLUSION: RHI combined with cf-PWV could improve the efficacy of predicting the presence of carotid plaques and their lengths.

Carotid plaque components and other carotid artery features associated with risk of stroke: A systematic review and meta-analysis.

OBJECTIVE: To compare the difference in the risk of stroke for four kinds of carotid artery plaque and carotid artery stenosis. METHODS: Literature was collected by searching the PubMed, Embase, Cochrane library and Ovid databases up to June 2022, using the free search terms "carotid plaque" and "stroke". Meta-analysis was performed on the selected articles using Stata16 to analyse the relationship of stroke risk factors. RESULTS: A total of 11 studies including 6661 participants were included. Meta-analysis results showed that the incidence of stroke was statistically significantly different between IPH (intraplaque haemorrhage) plaques and LRNC (lipid-rich necrotic core) plaques (RR: 1.27, 95% CI: 1.04-1.55, P < 0.05) and IPH plaques and calcification plaques (RR: 2.99, 95% CI: 1.74-5.14, P < 0.0001). Furthermore, there was a statistically significant difference between TRFC (thinned or ruptured fibrous caps) plaques and carotid artery stenosis (RR: 10.84, 95% CI: 5.60-20.98, P < 0.0001) and calcification plaques and carotid artery stenosis (RR: 0.83, 95% CI: 0.75-0.92, P < 0.0001). However, there was no statistically significant difference between the IPH and carotid artery stenosis (RR: 1.55, 95% CI: 0.68-3.52, P > 0.05), LRNC and TRFC (RR: 0.80, 95% CI: 0.11-5.82, P > 0.05), LRNC and calcification (RR: 1.81, 95% CI: 0.90-3.66, P > 0.05) and LRNC and carotid artery stenosis (RR: 1.40, 95% CI: 0.69-2.81, P > 0.05). CONCLUSION: IPH was associated with a higher incidence of stroke compared to LRNC and calcification plaques and TRFC has a higher risk of stroke than calcification plaques and carotid stenosis. This evidence suggests that IPH and TRFC may play an important role in predicting stroke.

Depression symptoms and quality of life in empty-nest elderly among Chengdu: A cross-sectional study.

Objectives: To estimate the prevalence of depression symptoms and quality of life (QoL) and examined the influence of factors in the empty nest elderly. Methods: This was a cross-sectional study, which was conducted from February 2022 to May 2022. We recruited a convenience sample of no empty-nest elderly and empty-nest elderly (≥60 years) living in Chengdu. QoL was assessed using WHOQOL-BREF, Geriatric Depression Scale (GDS-15) was used to assess depression symptoms. Multivariable logistic regression was used to analyze data between independent variables with depression symptoms. Results: Two thousand twenty-six participants were included in this study, 39.0% (660/1,082) experienced depression symptoms among empty-nest elderly. Age (aOR, 1.02; 95% CI, 1.00-1.04; P = 0.046), chronic disease≥2 (aOR, 3.29; 95% CI, 2.50-4.33; P < 0.001) were associated with increased risk of depression symptoms, and physical activity (aOR, 0.59; 95% CI, 0.40-0.87; P = 0.008), physical health (aOR, 0.93; 95% CI, 0.88-0.99; P = 0.026), psychological health (aOR, 0.93; 95% CI, 0.87-0.98; P = 0.013), and total score (aOR, 0.97; 95% CI, 0.96-0.99; P < 0.001) were associated with decreased risk of depression symptoms among empty-nest elderly. Conclusions: Depression symptoms are common mental health problems among empty-nest elderly. We found that age, chronic disease ≥2 and physical activity were important factors that have an impact on depressive symptoms. Empty-nest elderly would have lowered QoL score.

Risk factors for early neurological deterioration in acute isolated pontine infarction without any causative artery stenosis.

BACKGROUND: This study aimed to investigate the risk predictors for early neurological deterioration (END) in isolated acute pontine infarction without any causative artery stenosis. METHODS: In this retrospective study, patients with isolated acute pontine infarction within 72 h of symptom onset were enrolled between October 2017 and December 2021. END was defined as an increase in the National Institutes of Health Stroke Scale (NIHSS) score ≥ 2 points within the first week postadmission. Patients were divided into the END and the non-END groups. Multiple logistic regression analysis was used to evaluate independent predictors of END in patients with isolated acute pontine infarction. RESULTS: A total of 153 patients were included in the final study (62 females; mean age, 67.27 ± 11.35 years), of whom 28.7% (47 of 153) experienced END. Multiple logistic regression analyses showed that infarct volume (adjusted odds ratio [aOR], 1.003; 95% CI, 1.001-1.005; P = 0.002) and basilar artery branch disease  (aOR, 3.388; 95% CI, 1.102-10.417; P = 0.033) were associated with END. The combined ROC analysis of the infarct volume and basilar artery branch disease for predicting END showed that the sensitivity and specificity were 80.9% and 72.6%, respectively. CONCLUSION: Basilar artery branch disease and infarct volume were associated with END in acute isolated pontine infarction and may be useful prognostic factors for neurological progression.

Effect Evaluation of Comfort Nursing Materials Assisted Nursing for Patients with Advanced Malignant Tumor.

In order to explore the effect of comfort care on patients with advanced malignant tumors assisted by bioceramics, 82 patients with advanced malignant tumors admitted to a cancer hospital were selected as the research object control group: 26 males and 15 females and the observation group: 25 males and 16 females. The control group was given routine care, and the observation group was given comfort care on the basis of the control group. The quality of life (QLQ-C30 functional scale) and nursing satisfaction before and after nursing were compared between the two groups. The results of the study indicate that after care, the physical, role, emotional, cognitive, social, general health, and symptom scores of the observation group were significantly higher than those of the control group, the nursing satisfaction degree of the observation group was 97.56%, which was significantly higher than that of the control group of 82.93%, and the difference was statistically significant (P < 0.05). Comfortable care has a definite effect on the care of patients with advanced malignant tumors; it can improve the overall comfort and satisfaction of patients, effectively reduce adverse events, and improve the quality of life of patients.

Effect of intensive education on stroke prevention and management ability of community doctors: a cross-sectional study.

BACKGROUND: Prevention and treatment of stroke are extremely important to reduce the incidence of stroke-related disability and the associated death. This study aimed to investigate the current ability of community doctors in stroke management in the Jinjiang district of Chengdu, China, and the effect of intensive education on stroke prevention and management ability of these doctors. METHODS: A self-designed questionnaire was used to investigate the current status of stroke management by community doctors in the Jinjiang district. Subsequently, a series of intensive stroke management education courses for community doctors was designed according to the relevant guidelines for cerebrovascular accident prevention and treatment in China. All community doctors were trained, and their ability to treat and prevent stroke was reassessed using the self-designed questionnaire. RESULTS: Of the 450 questionnaires issued, 370 (82.2%) and 389 (86.4%) community doctors were enrolled before and after intensive education, respectively. The results showed that only 37.8% of the community doctors in the Jinjiang district knew the guidelines for the prevention and treatment of cerebrovascular diseases, and only 45.9% thought they had stroke management ability. The stroke management ability of community doctors improved after intensive education (p < 0.05), including pre-hospital identification and management of stroke, and management of its risk factors. CONCLUSIONS: The capacity of community doctors in the Jinjiang district of Chengdu is far from meeting the requirements of stroke prevention and treatment. However, the stroke management ability of the community doctors was greatly improved by promoting intensive education.

Numb inhibits migration and promotes proliferation of colon cancer cells via RhoA/ROCK signaling pathway repression.

Numb regulates cell proliferation and differentiation through endocytosis and ubiquitination of signaling molecules. Besides, Numb controls the migration of epithelial cells by regulating intercellular junctions. Studies have shown that Numb promotes or inhibits tumor progression in different tumors. However, its role and mechanism in colorectal cancer remain unclear. We found that the expression level of Numb in colon tumor tissues has a great variety in different patients. Numb expression was negatively correlated with TNM stage and lymph node metastasis but positively correlated with tumor size. Elevated expression of Numb was associated with a good prognosis. Inhibiting Numb expression promoted the migration and invasion of colon cancer cells induced by TGF-ß, up-regulated the expression of EMT-related molecule Snail, and prevented the expression of E-cadherin. We also found that Numb promoted the proliferation and clones formation while inhibiting colon cancer cells' late apoptosis. In addition, Numb inhibited the RhoA activation and ROCK inhibitor Y-27632 or interfered with ROCK expression, partially inhibiting Numb-regulated cell proliferation and migration. In vivo tumorigenesis assay in nude mice also found that Numb promoted the proliferation of colon cancer cells, inhibited the expression of E-cadherin, and strengthened the expression of Snail. In conclusion, our study found that Numb plays multiple roles in the occurrence and progression of colon cancer by regulating the RhoA/ROCK signaling pathway, which provides a new theoretical molecular basis for the pathogenesis of colon cancer.

IL-6 Accelerates the Proliferation and Metastasis of Pancreatic Cancer Cells via the miR-455-5p/IGF-1R Axis.

Background: Pancreatic cancer (PaC) is a highly malignant gastrointestinal tumor with invasive and metastatic characteristics. Interleukin-6 (IL-6), a negative prognostic marker, contributes to PaC progression. However, the mechanism of IL-6 in PaC is not yet fully understood. Methods: miR-455-5p levels were first tested by reverse transcription-quantitative polymerase chain reaction (RT-qPCR) in PaC tissues or cells. Subsequently, PaC cell-related functions were identified through CCK-8, Transwell, and Western blotting. Changes in miR-455-5p and IGF-1R expression were confirmed using RT-qPCR and Western blotting. miR-455-5p methylation was assessed by bisulfite sequencing PCR. Results: The authors discovered that miR-455-5p was expressed at low levels in PaC tissues and cells, and miR-455-5p expression was observably reduced by IL-6 in PaC cells. In addition, IL-6 dramatically induces miR-455-5p methylation in PaC cells. Functionally, the data revealed that IL-6 could facilitate the malignant properties of PaC cells, including proliferation, epithelial-mesenchymal transition, and metastasis. The authors found that miR-455-5p could suppress the progression of PaC cells by downregulating IGF-1R in PaC cells. Mechanistically, IL-6 downregulated miR-455-5p and upregulated IGF-1R, and miR-455-5p reduced IGF-1R expression through targeted binding. Conclusions: The authors demonstrated that the miR-455-5p/IGF-1R axis is necessary for the induction of IL-6 in PaC progression. Therefore, this study might provide a theoretical basis for the application of the IL-6/miR-455-5p/IGF-1R axis in the clinical therapy of PaC.

The length of susceptibility vessel sign predicts early neurological deterioration in minor acute ischemic stroke with large vessel occlusion.

BACKGROUND: Patients with acute large vessel occlusion (LVO) presenting with minor stroke are at risk of early neurological deterioration (END). The present study aimed to evaluate the frequency and potential predictors of END in patients with medical management and LVO presenting with minor stroke. The relationship between SVS length and END was also investigated. METHODS: This was a prospective multicenter study. Consecutive patients were collected with anterior circulation. LVO presented with minor stroke [National Institutes of Health Stroke Scale (NIHSS) ≤ 4] within 24 h following onset. END was defined as a deterioration of NIHSS ≥4 within 24 h, without parenchymal hemorrhage. The length of the susceptibility vessel sign (SVS) was measured using the T2* gradient echo imaging. RESULTS: A total of 134 consecutive patients with anterior circulation LVO presenting with minor stroke were included. A total of 27 (20.15%) patients experienced END following admission. Patients with END exhibited longer SVS and higher baseline glucose levels compared with subjects lacking END (P < 0.05). ROC curve analysis indicated that the optimal cutoff point SVS length for END was SVS ≥ 9.45 mm. Multivariable analysis indicated that longer SVS [adjusted odds ratio (aOR), 2.03; 95% confidence interval (CI), 1.45-2.84; P < 0.001] and higher baseline glucose (aOR,1.02; 95% CI, 1.01-1.03; P = 0.009) levels were associated with increased risk of END. When SVS ≥ 9.45 mm was used in the multivariate logistic regression, SVS ≥ 9.45 mm (aOR, 5.41; 95%CI, 1.00-29.27; P = 0.001) and higher baseline glucose [aOR1.01; 95%CI, 1.00-1.03; P = 0.021] were associated with increased risk of END. CONCLUSIONS: END was frequent in the minor stroke patients with large vessel occlusion, whereas longer SVS and higher baseline glucose were associated with increased risk of END. SVS ≥ 9.45 mm was a powerful independent predictor of END.

Laryngeal myasthenia gravis following influenza vaccination: a case report and literature review.

BACKGROUND: Myasthenia gravis (MG) is an autoimmune disease of acquired neuromuscular junction transmission disorder mediated by auto-antibodies. Extranophthalmic muscles are the most susceptible to MG, while the larynx muscle may also be affected. MG can be aggravated by various types of drugs. In the present study, a patient with laryngeal MG who received an influenza vaccination 5 days before onset was treated, which has not been previously reported. CASE PRESENTATION: A 58-year-old Asian woman developed mild dysphagia and severe dysarthria five days after receiving a trivalent inactivated influenza vaccine. The patient's quantitative MG score was 4 (1 for swallowing and 3 for speech), and the patient's neurological symptoms varied. The serum acetylcholine receptor (AChR) antibody titer was 0.67 nmol/L (normal range below 0.2 nmol/L), and other immunological and thyroid function tests were negative. As revealed by chest computed tomography (CT), there was no thymus abnormality. Based on the patient's history, clinical features, and examination results, the patient was diagnosed with laryngeal MG. The patient received pyridostigmine oral administration (60 mg/d) and steroid therapy (Prednisone, oral, 60 mg/d). The patient's symptoms began to improve after 7 days of treatment, and were significantly relieved after 2 weeks. CONCLUSION: Influenza vaccination might cause an unexpected abnormal autoimmune response in MG as a very rare event. Further research is needed to assess the possible causal relationship between the influenza vaccine and neurological complications, also in addition to the safety of the vaccine.

Risk Factors for Anxiety and Depressive Symptoms in Doctors During the Coronavirus Disease 2019 Pandemic.

Background: The purpose of our study was to investigate the prevalence of anxiety and depressive symptoms and their risk factors among doctors during the coronavirus disease 2019 (COVID-19) pandemic. Methods: A hospital-based survey study was conducted. Anxiety symptoms were assessed using the Self-Rating Anxiety Scale (SAS), and depressive symptoms were assessed using the Self-Rating Depression Scale (SDS). Multivariable logistic regression was used to analyze anxiety and depressive symptoms across independent variables. Results: A total of 1,521 doctors were included; 11.11% (169/1,521) of the doctors had anxiety symptoms, and 16.90% (257/1,521) had depressive symptoms. Female sex [adjusted odds ratio (aOR), 1.69; 95% confidence interval (CI), 1.21-2.34; P = 0.002] and having a minor child (aOR, 2.31; 95% CI, 1.50-3.56; P < 0.001) were associated with an increased risk of anxiety symptoms. Female sex (aOR, 1.56; 95% CI, 1.18-2.06; P = 0.002) and having a minor child (aOR, 1.48; 95% CI, 1.06-2.01; P = 0.022) were associated with an increased risk of depressive symptoms. Older age (aOR, 0.97; 95% CI, 0.98-0.99; P = 0.008) was associated with a decreased risk of depressive symptoms. Conclusions: Anxiety and depressive symptoms have been common mental health problems in doctors during the COVID-19 pandemic. We found that female sex, having a minor child, and younger age were major risk factors for the development of anxiety and depressive symptoms among doctors during the COVID-19 pandemic.
