Anxiety and depression among medical staff facing SARS-CoV-2 vaccination in China.

BACKGROUND: SARS-COV-2 vaccination is being carried out worldwide. However, little is known about the effect of SARS-COV-2 vaccination on psychological problems faced by the medical staff. This study aimed to examine the prevalence and factors contributing to anxiety and depression among medical staff facing SARS-COV-2 vaccination. METHODS: The GAD-7 and the PHQ-9 scales were used to investigate the anxiety and depression among participants involved in SARS-CoV-2 vaccination. Multivariate logistics regression analysis method was used to assess the risk factors related to anxiety or depression. RESULTS: A total of 6984 people responded to all the surveyed questions in our study, including 2707 medical staff and 4277 nonmedical staff. Of the participants, 680 reported anxiety, while 1354 reported depression. Higher anxiety levels were observed among medical staff (13.1 % vs. 7.6 % among the non-medical staff). Participants suffered from depression with higher numbers among medical staff (24.7 % vs. 16.0 % among the non-medical staff). Multivariate logistic regression analysis showed that female medical staff was at higher risk of anxiety and depression compared to their male counterparts (OR = 1.497; OR = 1.417). Pregnancy intention increased the risk of anxiety and depression among medical staff (OR = 1.601; OR = 1.724). LIMITATIONS: Our findings may not be extrapolated to other countries. CONCLUSION: Medical staff facing SARS-CoV-2 vaccination were more likely to suffer from anxiety or depression, especially the females planning for pregnancy. These results should assist in updating intervention guidelines for the mental health of medical staff facing vaccination.

Prevalence and risk factors of depression and anxiety among Chinese adults who received SARS-CoV-2 vaccine - A cross-sectional survey.

BACKGROUND: Direct data reflecting the psychological problems during the nationwide SARS-CoV-2 vaccination campaign are scarce in China. The aim of this study was to assess the prevalence of depression and anxiety and investigate the associated risk factors after vaccination against SARS-CoV-2 among Chinese adults. METHODS: We conducted a web-based cross-sectional survey from June to July 2021. A structured questionnaire including the Patient Health Questionnaire-9(PHQ-9) and Generalized Anxiety Disorder-7(GAD-7) was used to investigated depression and anxiety symptoms. After excluding 223 ineligible records, a total of 6984 participants were included in our final analysis. Multivariable logistic regression analysis was used to examined the potential factors associated with depression or anxiety. RESULTS: Our data indicated that the overall prevalence of depression and anxiety was assessed at 19.39 % and 9.74 %, respectively. Participants who had vaccinated the second dose were more likely to have depressive symptoms (20.95 % vs.16.40 %) and anxiety symptoms (10.38 % vs. 8.51 %) than who had vaccinated the first dose. Multivariable logistic regression analysis indicated female gender, being healthcare worker, college or above and planning a pregnancy were all independently linked to depression or anxiety. LIMITATIONS: The present study was based on an online survey. CONCLUSION: The present study confirmed the presence of depression and anxiety among Chinese adults who received SARS-COV-2 vaccine, as well as the potential influencing factors. Additional attention and psychological support should be directed at these high-risk groups during SARS-CoV-2 vaccination campaign.

Clinical features of NOTCH2NLC-related neuronal intranuclear inclusion disease.

BACKGROUND: Abnormal expanded GGC repeats within the NOTCH2HLC gene has been confirmed as the genetic mechanism for most Asian patients with neuronal intranuclear inclusion disease (NIID). This cross-sectional observational study aimed to characterise the clinical features of NOTCH2NLC-related NIID in China. METHODS: Patients with NOTCH2NLC-related NIID underwent an evaluation of clinical symptoms, a neuropsychological assessment, electrophysiological examination, MRI and skin biopsy. RESULTS: In the 247 patients with NOTCH2NLC-related NIID, 149 cases were sporadic, while 98 had a positive family history. The most common manifestations were paroxysmal symptoms (66.8%), autonomic dysfunction (64.0%), movement disorders (50.2%), cognitive impairment (49.4%) and muscle weakness (30.8%). Based on the initial presentation and main symptomology, NIID was divided into four subgroups: dementia dominant (n=94), movement disorder dominant (n=63), paroxysmal symptom dominant (n=61) and muscle weakness dominant (n=29). Clinical (42.7%) and subclinical (49.1%) peripheral neuropathies were common in all types. Typical diffusion-weighted imaging subcortical lace signs were more frequent in patients with dementia (93.9%) and paroxysmal symptoms types (94.9%) than in those with muscle weakness (50.0%) and movement disorders types (86.4%). GGC repeat sizes were negatively correlated with age of onset (r=-0.196, p<0.05), and in the muscle weakness-dominant type (median 155.00), the number of repeats was much higher than in the other three groups (p<0.05). In NIID pedigrees, significant genetic anticipation was observed (p<0.05) without repeat instability (p=0.454) during transmission. CONCLUSIONS: NIID is not rare; however, it is usually misdiagnosed as other diseases. Our results help to extend the known clinical spectrum of NOTCH2NLC-related NIID.

Computer-generated full-color phase-only hologram using a multiplane iterative algorithm with dynamic compensation.

Depth-division multiplexing (DDM) is a common method for full-color hologram generation. However, this method will result in uneven image-quality levels at different color channels of the original color image. In this paper, the DDM method with dynamic compensation is proposed for a full-color holographic display. Three monochromatic images of red (R), green (G), and blue (B) channels from the original color image are placed orderly at different positions (object planes) of the same optical axis; then, the complex amplitudes of the three object planes are iteratively updated in a designed order when a laser wavefront propagates between object planes and the hologram plane. In the iterative process, a dynamic compensation factor is added to the complex amplitude of each object plane, which can effectively balance the quality level of the reconstructed image in each color channel. As a result, the image quality of a full-color object is improved. Numerical simulation and optical experiments are carried out to verify the method's feasibility.

Diagnosis of Enterococcus faecalis meningitis associated with long-term cerebrospinal fluid rhinorrhoea using metagenomics next-generation sequencing: a case report.

BACKGROUND: Enterococcus faecalis (E. faecalis) meningitis is a rare disease, and most of its occurrences are of post-operative origin. Its rapid diagnosis is critical for effective clinical management. Currently, the diagnosis is focused on cerebrospinal fluid (CSF) culture, but this is quite limited. By comparison, metagenomic next-generation sequencing (mNGS) can overcome the deficiencies of conventional diagnostic approaches. To our knowledge, mNGS analysis of the CSF in the diagnosis of E. faecalis meningitis has been not reported. CASE PRESENTATION: We report the case of E. faecalis meningitis in a 70-year-old female patient without a preceding history of head injury or surgery, but with an occult sphenoid sinus bone defect. Enterococcus faecalis meningitis was diagnosed using mNGS of CSF, and she recovered satisfactorily following treatment with appropriate antibiotics and surgical repair of the skull bone defect. CONCLUSIONS: Non-post-traumatic or post-surgical E. faecalis meningitis can occur in the presence of occult defects in the cranium, and mNGS technology could be helpful in diagnosis in the absence of a positive CSF culture.

Detection of meningoencephalitis caused by Listeria monocytogenes with ischemic stroke-like onset using metagenomics next-generation sequencing: A case report.

RATIONALE: Listeria monocytogenes (L. monocytogenes) is a compatible intracellular bacterial pathogen that can invade different mammalian cells and reach the central nervous system (CNS), leading to meningoencephalitis and brain abscesses. In the diagnosis of L. monocytogenes meningoencephalitis (LMM), conventional tests are often reported as negative due to antibiotic therapy or low bacterial content in cerebrospinal fluid. To date, prompt diagnosis and accurate treatment remain a challenge for patients with Listeria infections. PATIENT CONCERNS: Here, we report a case of a 64-year-old male diagnosed with LMM by using metagenomics next-generation sequencing (mNGS). DIAGNOSIS: LMM was confirmed by mNGS analysis of cerebrospinal fluid. INTERVENTIONS: The patient was treated with piperacillin and sensitive antibiotics. OUTCOMES: The patient could walk independently about 1 month after admission and was discharged from the hospital. LESSONS: This case highlights the value of mNGS in the diagnosis of LMM and emphasizes the inadequate sensitivity of conventional diagnostic methods for Listeria infection.

Idiopathic thrombocytopenic purpura with brain abscess caused by Nocardia farcinica diagnosed using metagenomics next-generation sequencing of the cerebrospinal fluid: a case report.

BACKGROUND: Brain abscesses caused by Nocardia farcinica are rare, and mostly occur in immunocompromised individuals. Rapid and accurate diagnosis of nocardiosis is challenging. Due to the inadequate performance of conventional diagnostic methods for Nocardia infection, metagenomics next-generation sequencing (mNGS) of cerebrospinal fluid (CSF) has the potential to improve the diagnosis intracranial nocardiosis. CASE PRESENTATION: We report a case of 50-year-old man with brain abscess caused by Nocardia farcinica. The patient had a idiopathic thrombocytopenic purpura complication that required long-term methylprednisolone administration. His chest image showed multiple lesions, which had been misdiagnosed as lung cancer, and his head image showed multiple intracranial metastases. No pathogen was detected in routine examinations including blood culture, sputum culture and traditional culture methods of cerebrospinal fluid. In order to accurately identify the pathogen, mNGS was used to detect Nocardia in CSF. Although the patient's condition improved after using sensitive antibiotics, he transferred to the local hospital for treatment because of many complicated diseases and family financial limitations. CONCLUSION: This case highlights the value of mNGS in the diagnosis of Nocardia brain abscess, and emphasizes the inadequate sensitivity of conventional diagnostic methods for Nocardia infection. Using mNGS can facilitate early and accurate detection of Norcadia-associated of meningitis in immunocompromised patients, thereby reducing unnecessary use of antibiotics and reducing mortality of the disease.

The role of genetics in Parkinson's disease: a large cohort study in Chinese mainland population.

This study aimed to determine the mutational spectrum of familial Parkinson's disease and sporadic early-onset Parkinson's disease (sEOPD) in a mainland Chinese population and the clinical features of mutation carriers. We performed multiplex ligation-dependent probe amplification assays and whole-exome sequencing for 1676 unrelated patients with Parkinson's disease in a mainland Chinese population, including 192 probands from families with autosomal-recessive Parkinson's disease, 242 probands from families with autosomal-dominant Parkinson's disease, and 1242 sEOPD patients (age at onset ≤ 50). According to standards and guidelines from the American College of Medical Genetics and Genomics, pathogenic/likely pathogenic variants in 23 known Parkinson's disease-associated genes occurred more frequently in the autosomal-recessive Parkinson's disease cohort (65 of 192, 33.85%) than in the autosomal-dominant Parkinson's disease cohort (10 of 242, 4.13%) and the sEOPD cohort (57 of 1242, 4.59%), which leads to an overall molecular diagnostic yield of 7.88% (132 of 1676). We found that PRKN was the most frequently mutated gene (n = 83, 4.95%) and present the first evidence of an SNCA duplication and LRRK2 p.N1437D variant in mainland China. In addition, several novel pathogenic/likely pathogenic variants including LRRK2 (p.V1447M and p.Y1645S), ATP13A2 (p.R735X and p.A819D), FBXO7 (p.G67E), LRP10 (c.322dupC/p.G109Rfs*51) and TMEM230 (c.429delT/p.P144Qfs*2) were identified in our cohort. Furthermore, the age at onset of the 132 probands with genetic diagnoses (median, 31.5 years) was about 14.5 years earlier than that of patients without molecular diagnoses (i.e. non-carriers, median 46.0 years). Specifically, the age at onset of Parkinson's disease patients with pathogenic/likely pathogenic variants in ATP13A2, PLA2G6, PRKN, or PINK1 was significantly lower than that of non-carriers, while the age at onset of carriers with other gene pathogenic/likely pathogenic variants was similar to that of non-carriers. The clinical spectrum of Parkinson's disease-associated gene carriers in this mainland Chinese population was similar to that of other populations. We also detected 61 probands with GBA possibly pathogenic variants (3.64%) and 59 probands with GBA p.L444P (3.52%). These results shed insight into the genetic spectrum and clinical manifestations of Parkinson's disease in mainland China and expand the existing repertoire of pathogenic or likely pathogenic variants involved in known Parkinson's disease-associated genes. Our data highlight the importance of genetic testing in Parkinson's disease patients with age at onset < 40 years, especially in those from families with a recessive inheritance pattern, who may benefit from early diagnosis and treatment.

A novel compound heterozygous EPM2A mutation in a Chinese boy with Lafora disease.

EPM2A has been certified as a causative gene in patients with Lafora disease (LD), which is a rare autosomal recessive and severe form of progressive myoclonus epilepsy. LD classically starts in adolescence, characterized by various types of seizure with myoclonic seizure as the main type. Typically within 10 years, intractable seizure attack, rapidly progressing dementia, and a vegetative state were present. LD is particularly frequently found in Mediterranean countries. Here, we report a Chinese family with a novel compound heterozygous mutation in the EPM2A gene, characterized by recurrent vomiting, intractable epilepsy, and progressive cognitive decline.

Expansion of Human-Specific GGC Repeat in Neuronal Intranuclear Inclusion Disease-Related Disorders.

Neuronal intranuclear inclusion disease (NIID) is a slowly progressing neurodegenerative disease characterized by eosinophilic intranuclear inclusions in the nervous system and multiple visceral organs. The clinical manifestation of NIID varies widely, and both familial and sporadic cases have been reported. Here we have performed genetic linkage analysis and mapped the disease locus to 1p13.3-q23.1; however, whole-exome sequencing revealed no potential disease-causing mutations. We then performed long-read genome sequencing and identified a large GGC repeat expansion within human-specific NOTCH2NLC. Expanded GGC repeats as the cause of NIID was further confirmed in an additional three NIID-affected families as well as five sporadic NIID-affected case subjects. Moreover, given the clinical heterogeneity of NIID, we examined the size of the GGC repeat among 456 families with a variety of neurological conditions with the known pathogenic genes excluded. Surprisingly, GGC repeat expansion was observed in two Alzheimer disease (AD)-affected families and three parkinsonism-affected families, implicating that the GGC repeat expansions in NOTCH2NLC could also contribute to the pathogenesis of both AD and PD. Therefore, we suggest defining a term NIID-related disorders (NIIDRD), which will include NIID and other related neurodegenerative diseases caused by the expanded GGC repeat within human-specific NOTCH2NLC.

A sample model established by S-index predicting overall survival after curative resection of primary hepatocellular carcinoma.

PURPOSE: Prognostic prediction after curative resection of primary hepatocellular carcinoma (PHCC) remains an arduous task. The S-index calculated from γ-glutamyl transpeptidase, albumin, and platelets is reported to predict the severity of liver fibrosis. We constructed a nomogram for predicting the survival probability of PHCC based on a new indicator, the S-index, combined with other routine clinical parameters. PATIENTS AND METHODS: We selected 490 patients with PHCC postradical surgery at the First Affiliated Hospital of Wenzhou Medical University between January 2007 and January 2014. The subjects were randomly allocated into the training cohort and the validation cohort in the ratio 7:3 by the digital method. Important variables screened by univariate analysis were included in multivariate analysis to obtain independent risk factors for predicting the prognosis of PHCC. The construction of the nomogram was based on Cox proportional hazard regression models. The concordance index (C-index) was used in the nomogram for evaluating the model performance for prognosis. We drew time-dependent receiver operating characteristic curves to compare our model with other staging systems. RESULTS: The nomogram based on six independent risk factors after multivariate analyses had good predictive power after radical surgery of PHCC. In the training and validation groups, the C-index of the nomogram was highly consistent for evaluating survival from PHCC. Compared with the traditional scoring system, the areas under time-dependent receiver operating characteristic curves were 0.7382, 0.7293, and 0.7520 for 1-, 3-, and 5-year overall survival, respectively. In summary, the nomogram showed excellent results in terms of prognosis of PHCC. CONCLUSION: Based on the S-index and the other clinical indicators, we developed a precise nomogram that predicts the survival probability of patients with PHCC after radical surgery. This tool can provide effective information for surgeons and patients.

Expression of microRNA 638 and sex-determining region Y-box 2 in hepatocellular carcinoma: Association between clinicopathological features and prognosis.

The aim of the present study was to determine the expression profile of microRNA 638 (miR-638) and sex-determining region Y-box 2 (SOX2) in hepatocellular carcinoma (HCC), and to investigate their association with clinicopathological features and survival. Reverse transcription-quantitative polymerase chain reaction analysis was used to investigate miR-638 and SOX2 expression in 78 patients with HCC. Western blot and immunohistochemical analyses were performed in order to determine SOX2 protein expression in HCC samples. Combined with the clinical postoperative follow-up data, the expression of miR-638 and SOX2 and the association between this and the prognostic values of patients with HCC were statistically analyzed. The results of the present study confirmed that miR-638 expression in tumor tissues was significantly downregulated (P<0.001), while SOX2 expression was significantly increased, compared with healthy control tissues (P<0.05). In addition, a significant inverse correlation between miR-638 and SOX2 expression was also observed in the HCC tissues (r=-0.675; P<0.05). Clinicopathological correlation analysis demonstrated that reduced miR-638 and elevated SOX2 expression was significantly associated with the Tumor-Node-Metastasis stage and portal vascular invasion (P<0.05). However, no significant differences were observed in other clinicopathological features, including age, sex, tumor size, tumor differentiation and hepatitis status (P>0.05). Notably, follow-up analysis revealed that patients with HCC with low miR-638 expression and high SOX2 expression tended to have a significantly shorter postoperative survival time (P<0.001). It was concluded that miR-638 may serve a vital role in the occurrence and progression of HCC by regulating SOX2 expression and thus, that miR-638 and SOX2 may be critical as novel diagnostic and prognostic biomarkers for HCC.
