The COVID-19 pandemic has had a great impact on the mental health of the medical staff in China, especially those on the first-line (frontline) of the pandemic. But the profile of the mental problem of nationwide Chinese medical staff is still unclear, especially about the sleep problems.
There are five databases (PubMed, Embase, CNKI, Wanfang Database and Web of Science) searched to identify the published studies on the mental health of the medical staff in China during the COVID-19 outbreak. The pooled prevalence of mental problems of Chinese medical staff during the pandemic were calculated, especially for the first-line medical staff. Subgroup analysis and meta-regression analysis were performed to identify the potential impact factors.
A total of 71 articles including 98,533 participants are included in this meta-analysis. The results showed that the pooled prevalence of the mental problems was as follows anxiety problem 27%, depression problem 29%, sleep problem 40%. Subgroup analysis showed that there were significant differences in the prevalence of anxiety and depression problems between first-line and non-first-line medical staff (p < 0.01). Sex had a significant impact on the sleep of first-line medical staff (p < 0.01).
There may be heterogeneity among the included studies. The analysis of potential influencing factors remains limited.
The prevalence of adverse mental problems among medical staff is high during the COVID-19 outbreak. We need to pay special attention to the mental health of first-line medical staff, especially the sleep problems of female first-line workers.

Only selected effects of amylin are discussed here because we recently published extensive reviews on the physiology and pathophysiology of amylin. Amylin was discovered as the main constituent of islet amyloid that is predominantly found in pancreatic islets in type 2 diabetics. These deposits, and in particular small oligomer aggregates of amylin seem to contribute to the progressive beta-cell damage seen in type 2 diabetics. Amylin is also a physiologically relevant circulating hormone with diverse metabolic functions, e.g. inhibition of eating, of pancreatic glucagon secretion and of gastric emptying. Knowledge of these types of functions and amylin's mechanisms of action lead to the development of amylin analogues that are now among the most promising anti-obesity targets in clinical testing. With this review, I want to give a short overview of 35 exciting years of amylin research.The 5xFAD mouse model of Alzheimer's disease (AD) develops age-related neuropathology and sensory, motor, and cognitive impairments. The purpose of this study was to examine whether age-related changes in motor function affected working memory performance in 5xFAD mice in the Hebb-Williams Maze (HWM). At 6 months of age, the 5xFAD mice performed better than the WT (B6SJL) mice on the accelerating rotarod, but much worse at 12 months of age. The 5xFAD and WT mice did not differ in days to acquisition in the HWM at 6 months of age, but the WT mice took longer at 12 months of age. The number of errors increased with maze difficulty and at 6 months of age, the 5xFAD mice made more errors than the WT mice only on difficult problems. At 12 months of age 5xFAD mice made more errors than WT mice at each level of problem difficulty. The latency to solve the problems was higher for the 5xFAD mice than the WT mice in the difficult problems at 6 months of age and in the intermediate problems at 12 months of age. ML323 Although body weight had some effect on rotarod performance, there were no systematic effects of motor deficits on either errors or latency measures in the test trials of the HWM. These results indicate that the 5xFAD mice had deficits in working memory in the HWM and that these deficits were not confounded by impaired motor performance.Disorders such as Trichotillomania (TTM) and skin-picking disorder (SPD) are associated with reduced flexibility and increased internally focused attention. While the basal ganglia have been hypothesized to play a key role, the mechanisms underlying learning and flexible accommodation of new information is unclear. Using a Bayesian Learning Model, we evaluated the neural basis of learning and accommodation in individuals with TTM and/or SPD. Participants were 127 individuals with TTM and/or SPD (TTM/SPD) recruited from three sites (age 18-57, 84% female) and 26 healthy controls (HC). During fMRI, participants completed a shape-button associative learning and reversal fMRI task. Above-threshold clusters were identified where the Initial Learning-Reversals BOLD activation contrast differed significantly (p less then .05 FDR-corrected) between the two groups. A priori, effects were anticipated in predefined ROIs in bilateral basal ganglia, with exploratory analyses in the hippocampus, dorsolateral prefrontal cortex (dlPFC), and dorsal anterior cingulate cortex (dACC). Relative to HC, individuals with TTM/SPD demonstrated reduced activation during initial learning compared to reversal learning in the right basal ganglia. Similarly, individuals with TTM/SPD demonstrated reduced activation during initial learning compared to reversal learning in several clusters in the dlPFC and dACC compared to HC. Individuals with TTM/SPD may form or reform visual stimulus-motor response associations through different brain mechanisms than healthy controls. The former exhibit altered activation within the basal ganglia, dlPFC, and dACC during an associative learning task compared to controls, reflecting reduced frontal-subcortical activation during initial learning. Future work should determine whether these neural deficits may be restored with targeted treatment.Glutamate is the major fast excitatory neurotransmitter in the nervous system, and researchers have for decades pursued tools for monitoring glutamate release in real time. Optical reporters, primarily genetically-encoded glutamate sensors, have developed into the predominant method, particularly following the advent of the intensity-based glutamate-sensing fluorescent reporter (iGluSnFR). Several variants have been developed to improve the performance of iGluSnFR in brightness, kinetics and spectral range. Following the targeting principle of other sensors for neurotransmission, iGluSnFR mutants tethered to pre- or postsynaptic targeting proteins should show enhanced properties for detecting glutamate release at central synapses.Periorbital necrotizing fasciitis carries serious risks of loss of vision, eye, and life, and thus represents a true emergency. As such, clinicians must have an appropriate index of suspicion for necrotizing fasciitis and, upon recognition, need to address the disease rapidly and thoroughly. I review the classic features, systemic implications, and management paradigms of necrotizing fasciitis in the hopes of improving outcomes.Nonrefractive accommodative esotropia (NRAET) is a form of pediatric acquired strabismus in which the accommodative convergence to accommodation (AC/A) ratio is high. Accordingly, the near angle of esotropia is notably greater than the distance angle, and after full-cycloplegic correction, the near angle is not fully resolved. Nonsurgical plans to deal with convergence-excess esotropia include observation only and single vision lenses with or without a ground-in plus addition power. Bifocals and progressive addition lenses (PALs) are two available designs when the preferred management approach is near plus addition. There are inconsistent data regarding the practical effectiveness of these two optical modalities in providing ocular alignment. Several studies advocated using bifocals and PALs as the primary management strategy in patients with NRAET; however, because of developmental concerns, others affirm that early surgical intervention can be a more conservative strategy than optical treatment. They noted that this method might be ineffective or even pernicious due to the need to defer the surgical intervention. In practice, the prescription of near plus addition lenses in the two forms of bifocals and PALs could be a double-edged sword in the treatment course of patients with NRAET. Therefore, an individualized approach according to the age, degree of refractive error, AC/A ratio, esotropia angle at distance and near, coexisting amblyopia, and parents' economic and cosmetic concerns would be important before choosing any treatment option.Imaging is an integral part of the evaluation and management of retinal disorders. Each imaging modality has its own unique capabilities and can show a different aspect or perspective of disease. Multimodal retinal imaging provides a wealth of substantive and insightful information; however, the integration of all this complex data can be overwhelming. We discuss the applications and the strengths and limitations of the many different retinal imaging tools that are approved for clinical use. These modalities include color fundus photography, widefield imaging, fundus autofluorescence, near infrared reflectance, optical coherence tomography angiography, and en face optical coherence tomography. We also cover the advantages and disadvantages of a multimodal approach.Contact dermatitis is a common disease that is caused by repeated skin contact with contact allergens or irritants, resulting in allergic contact dermatitis (ACD) and/or irritant contact dermatitis. Attempts have been made to identify biomarkers to distinguish irritant and allergic patch test reactions, which could aid diagnosis. Some promising candidates have recently been identified, but verification and validation in clinical cases still need to be done. New causes of ACD are constantly being recognized. In this review, 10 new contact allergens from recent years, several relating to anti-aging products, have been identified. Frequent allergens causing considerable morbidity in the population, such as the preservative methylisothiazolinone, have been regulated in the European Union. A significant drop in the number of cases has been seen, whereas high rates are still occurring in other areas such as North America. Other frequent causes are fragrance allergens, especially the widely used terpenes and acrylates found in medical devices for control of diabetes. These represent unsolved problems. Recent advances in immunology have opened the way for a better understanding of the complexity of contact dermatitis, especially ACD-a disease that may be more heterogenous that previous understood, with several subtypes. With the rapidly evolving molecular understanding of ACD, the potential for development of new drugs for personalized treatment of contact dermatitis is considerable.
