Introduction: Stroke is a life-threatening condition that increasingly damages cerebral tissue over time and can lead to serious post-effects, including depression, which can hinder a patient's recovery from stroke and reduce quality of life. This paper aims to analyze the global research landscape of post-stroke depression (PSD) between the years 1900 to 2024 using bibliometric analysis. Methods: The data used in this analysis was collected from the Web of Science Core Collection (WoSCC). An advanced search was performed using the keywords, "stroke" and "depression," on July 8th, 2024. From the Web of Science, bibliometric data was then extracted and analyzed in VOSviewer through four categories: countries, number of publications, keywords, and journals. Results: The bibliometric analysis resulted in 2,289 publications from the year 1900 to 2024. A gradual increase in the number of publications on post-stroke depression over the study period was observed. China was found to be the leading country for publications and funding on PSD, with the United States following in second. The top keywords included: "stroke," "depression," and "poststroke depression." The Journal of Stroke had the highest number of publications on depression in post-stroke patients. Conclusion: This study provides an overview of the current trends in articles published on PSD. Depression is an important topic to be considered in post-stroke patients due to its negative effects on post-stroke recovery and reduced quality of life, necessitating a call to attention and support for future research in this field. With continued research efforts led by the United States and China, improved treatments for patients with post-stroke depression can be implemented. [ABSTRACT FROM AUTHOR]

Prior research suggests that collectivism predicts international consumers' compliance with COVID-19 preventive behaviors. However, across two cross-sectional studies, we demonstrated that Chinese consumers were more likely to wear face masks and stay at home; while U.S. consumers were more likely to wash hands and keep a social distance. Indeed, when U.S. consumers perceived the pandemic to be more severe and were more health-conscious, they were more likely to comply with COVID-19 preventive behaviors than the Chinese. Adopting a multifactorial model, we offer a holistic view of consumer responses to COVID-19. We also provide insights for marketers and policymakers. [ABSTRACT FROM AUTHOR]

Introduction: The emergence of artificial intelligence (AI) chat programs has opened two distinct paths, one enhancing interaction and another potentially replacing personal understanding. Ethical and legal concerns arise due to the rapid development of these programs. This paper investigates academic discussions on AI in medicine, analyzing the context, frequency, and reasons behind these conversations. Methods: The study collected data from the Web of Science database on articles containing the keyword "ChatGPT" published from January to September 2023, resulting in 786 medically related journal articles. The inclusion criteria were peer-reviewed articles in English related to medicine. Results: The United States led in publications (38.1%), followed by India (15.5%) and China (7.0%). Keywords such as "patient" (16.7%), "research" (12%), and "performance" (10.6%) were prevalent. The Cureus Journal of Medical Science (11.8%) had the most publications, followed by the Annals of Biomedical Engineering (8.3%). August 2023 had the highest number of publications (29.3%), with significant growth between February to March and April to May. Medical General Internal (21.0%) was the most common category, followed by Surgery (15.4%) and Radiology (7.9%). Discussion: The prominence of India in ChatGPT research, despite lower research funding, indicates the platform's popularity and highlights the importance of monitoring its use for potential medical misinformation. China's interest in ChatGPT research suggests a focus on Natural Language Processing (NLP) AI applications, despite public bans on the platform. Cureus' success in publishing ChatGPT articles can be attributed to its open-access, rapid publication model. The study identifies research trends in plastic surgery, radiology, and obstetric gynecology, emphasizing the need for ethical considerations and reliability assessments in the application of ChatGPT in medical practice. Conclusion: ChatGPT's presence in medical literature is growing rapidly across various specialties, but concerns related to safety, privacy, and accuracy persist. More research is needed to assess its suitability for patient care and implications for non-medical use. Skepticism and thorough review of research are essential, as current studies may face retraction as more information emerges. [ABSTRACT FROM AUTHOR]

While access to school is one crucial aspect of education equality, there is a lack of research on factors that influence the distance that pupils travel to school. Previous studies have failed to reveal the relationship between pupils' socio-spatial characteristics and travel distance. This paper uncovers the multilevel structure, ignored hitherto, that underpins the determinants of pupils' travel distance. Using detailed travel survey data for Beijing and an appropriate multilevel modelling approach, this research reveals that contextual variation remains, having taken account of compositional (individual-level) variables; and that contextual factors, that is, school density and neighbourhood context, are more influential when compared with individual-level factors except for education stage and housing type. The policy implications include improved planning for schools in comparatively deprived areas, increased provision of affordable housing and enhanced education opportunities for migrant children.

An invasive population of spotted lanternfly (SLF), Lycorma delicatula White, was first noted in North America in Pennsylvania in 2014, and by September 2020 populations had spread to six additional states. To develop a biocontrol program to aid in the management of the pest, exploratory surveys for SLF natural enemies in its native range were carried out in 27 provinces and other administrative regions of China from 2015 to 2019. Naturally laid egg masses were collected and sentinel SLF egg masses were deployed to attract egg parasitoids, and yellow sticky traps were used to collect SLF nymphs to discover and determine the parasitism rates of nymphal parasitoids. Results show that SLF is widely distributed in China (22 provinces and regions) and that the population densities in northeast China are higher than in southern and western China. An egg parasitoid, Anastatus orientalis Yang (Hymenoptera: Eupelmidae), and a nymphal parasitoid, Dryinus sinicus Olmi (Hymenoptera: Dryinidae), were collected. Anastatus orientalis was reared from SLF eggs in seven provinces in China with parasitoid emergence rates ranging from 4.0 to 15.5% (or 17.6 to 37.3% if including only egg masses that had at least some parasitism). There were significant differences in parasitoid emergence rates between sites associated with factors including habitat and host plants. Dryinus sinicus was discovered in eight cities across six provinces. The percentage of SLF nymphs parasitized by D. sinicus were 31.1, 23.3, and 0% in Tai'an, Shandong Province, Beijing City, and Yan'an, Shaanxi Province, respectively. These two parasitoids are promising natural enemies that are being considered as potential biocontrol agents of invasive populations of SLF. [ABSTRACT FROM AUTHOR]

To support efforts to manage and contain spotted lanternfly (SLF), Lycorma delicatula White (Hemiptera: Fulgoridae), research is being conducted to develop classical biological control methods. To date, two potential biocontrol agents from China have been identified: an egg parasitoid, Anastatus orientalis, and a nymphal parasitoid, Dryinus sinicus Olmi (Hymenoptera: Dryinidae). The research detailed here focuses on investigating the biology and rearing of A. orientalis to assess its potential efficacy in a biocontrol program and optimize its rearing. Female wasps lived significantly longer than male wasps (68 and 23 d, respectively) and females produced an average of 94 total progeny that successfully emerged as adults, with most progeny produced between weeks one and four of the females' lives. The sex ratio of the progeny, with no re-mating, was initially highly female-biased but became progressively more male-biased, likely due to sperm depletion. There was no evidence of additional mortality to SLF eggs from wasp host feeding, but the data were highly variable and the sample size was small. There was high parasitoid emergence when oviposition conditions mimicked mid-September Beijing temperature and photoperiod; however, there was little emergence under 25°C and long-day conditions because most progeny entered a diapause. Storage of parasitized eggs in 5°C chill lowered parasitoid emergence rates. Lastly, there was no evidence that storing field-collected SLF egg masses in 5°C for 10 mo prior to parasitization affected parasitism rates. These findings inform our rearing protocol for A. orientalis and facilitate our testing of this species as a potential biological control agent for SLF. [ABSTRACT FROM AUTHOR]

Migratory insect pests pose a substantial challenge to global food security. These issues are particularly acute when pest incursions occur considerably beyond the expected range, through natural migration or human‐aided transport, because the lack of species‐specific control strategies and a potential absence of species‐specific natural enemies in the newly‐invaded area may lead to rapid establishment of a new pest.One such threat is posed by the Oriental migratory locust Locusta migratoria manilensis in China, which, historically, has been restricted to eastern China from the Bohai Gulf southwards, and now threatens to expand its range into the agriculturally important region of northeast China.We analyzed data from a recent outbreak of migratory locusts in Heilongjiang Province (extreme northeast China), > 700 km north of its current known range, and identified the source region, timing of arrival and probable migratory routes of this incursion.We further show that warming temperatures in this region will likely allow subsequent invasions to establish permanent populations in northeast China, and thus authorities in this important crop‐producing region of East Asia should be vigilant to the threat posed by this species.

BACKGROUND Transgenic cotton that expresses a gene derived from the bacterium Bacillus thuringiensis ( Bt) has been deployed for combating cotton bollworm in China since 1997. As a follow-up on research started in 2002, the quantitative shifts in larval Cry1Ac resistance of field Helicoverpa armigera populations were monitored from 2009-2013 using bioassays of isofemale lines. RESULTS A total of 2837 lines from Xiajin and 2055 lines from Anci were screened for growth rate on normal artificial diet and on a diet containing 1.0 µg mL−1 of Cry1A(c) toxin. In 2009-2013, the mean relative average development rates ( RADRs) of H. armigera larvae in the Xiajin population were 0.62, 0.59, 0.59, 0.58 and 0.62 respectively, and in the Anci population 0.54, 0.58, 0.60, 0.53 and 0.62 respectively. CONCLUSIONS Compared with previous results in 2002, there was an increase in the RADR of H. armigera during 2009-2013, with ratios of 1.53-1.63 and 1.77-2.07 in the respective Xiajin and Anci populations, suggesting that resistance to Cry1Ac has increased in H. armigera populations in northern China. © 2014 Society of Chemical Industry [ABSTRACT FROM AUTHOR]

Japanese encephalitis (JE) is arguably one of the most serious viral encephalitis diseases worldwide. China has a long history of high prevalence of Japanese encephalitis, with thousands of cases reported annually and incidence rates often exceeding 15/100,000. In global terms, the scale of outbreaks and high incidence of these pandemics has almost been unique, placing a heavy burden on the Chinese health authorities. However, the introduction of vaccines, developed in China, combined with an intensive vaccination program initiated during the 1970s, as well as other public health interventions, has dramatically decreased the incidence from 20.92/100,000 in 1971, to 0.12/100,000 in 2011. Moreover, in less readily accessible areas of China, changes to agricultural practices designed to reduce chances of mosquito bites as well as mosquito population densities have also been proven effective in reducing local JE incidence. This unprecedented public health achievement has saved many lives and provided valuable experience that could be directly applicable to the control of vector-borne diseases around the world. Here, we review and discuss strategies for promotion and expansion of vaccination programs to reduce the incidence of JE even further, for the benefit of health authorities throughout Asia and, potentially, worldwide.

Purpose – The Chinese capital markets are divided into two segments comprising of A-shares (traded by domestic investors) and B-shares (traded by foreign investors). Firms issuing A-shares are required to produce accounting reports under the Chinese Accounting Standards (CAS) and firms issuing B-shares are required to report under the International Accounting Standards (IAS). The purpose of this paper is to investigate the comparative value-relevance of accounting information in the Chinese capital markets, in particular whether the value-relevance associated IAS exceeds that of CAS. Design/methodology/approach – This study undertakes a capital market research approach. Two statistical models are employed to test the value-relevance of competing accounting information on share prices: the Price Model and the Return Model. This study takes advantage of the parallel reporting frameworks governing the A-share and B-share markets buy using the same firms which issue both A-shares and B-shares. Findings – The analysis supporting the study demonstrates that both CAS and IAS information is value relevant to investors in the Chinese capital markets but that IAS provide more useful information. Additionally it is observed that reconciliation variables (representing the discrepancy between IAS- and CAS-based accounting figures) are not significant in explaining market valuation or returns on stock. Research limitations/implications – This study provides evidence of value-relevance of accounting reports on the Chinese capital markets for the period of 1999-2005. The period under investigation captures the significant development in China's accounting regulations which took place in 1998 and 2001. The recent shift in accounting regulations in China from CAS to IAS is expected to improve the dissemination of financial information by publicly listed Chinese firms. Practical implications – This study investigates the reporting requirements on the Chinese capital markets during a period in which accounting reporting requirements underwent a significant change as part of the internationalization of accounting standards. Both A- and B-share markets were investigated simultaneously in order to provide an objective analysis and avoid sampling selection bias present in other studies. Social implications – The recent shift in accounting regulations in China from CAS to IAS is expected to improve the dissemination of financial information by publicly listed Chinese firms. Originality/value – This paper extends previous research on value-relevance of accounting reports in the Chinese capital markets by capturing the period in which the reporting requirements had experienced significant change. This paper also takes advantage of the dual reporting framework in order to mitigate potential sampling bias present in previous studies and employs a reconciliation variables not previously used.

Rainwater harvesting (RWH) has been widely practised in China for centuries. The modernization and rapid spread of RWH and accompanied low-cost greenhouse and low rate irrigation (LORI) techniques since the late 1980s has helped to address water shortages and lift millions of families out of poverty in semi-arid provinces such as Gansu. The construction of terraces, contour bunds and micro-catchments has also contributed significantly to soil and water conservation, revegetation and ecological restoration of previously degraded land. This article provides an update on developments relating to a major RWH programme in Gansu Province, China, and follows three previous contributions published by the authors in Waterlines in 1995, 2000, and 2006. It also provides an overview of the book Every Last Drop: Rainwater Harvesting and Sustainable Technologies in Rural China, published by Practical Action in 2012. [ABSTRACT FROM AUTHOR]

We undertake a range of tests for structural food preference change in urban China, using provincial-level panel data from 2002 to 2010. We introduce a time transition function into the Generalized Quadratic Almost Ideal Demand System (GQAIDS) to represent consumer preferences. We apply this system to evaluate the demand structure for seven food groups. The use of the GQAIDS specification relaxes many empirical demand system restrictions associated with previous analyses of structural preference change. Our findings suggest that Chinese food preferences are continuing to evolve. [ABSTRACT FROM AUTHOR]

This article examines food demand structure and its dynamics for 11 commodities in urban China. The analysis is based on household-level expenditure survey data for two cross-sectional surveys of Chinese households pertaining to food expenditure patterns during 1995 and 2003. Pre-committed components of commodity demands, that are insensitive to economic variables, are explored. We use the generalized quadratic almost ideal demand system (GQAIDS) for its empirical superiority to the generalized almost ideal demand system (GAIDS), and estimate the associated parameters via full information maximum likelihood procedure (FIML) accounting for endogeneity of total expenditures on food for home consumption (FAH). We also use quality-adjusted commodity unit values to control for quality differences resulting from commodity aggregation and food choice. Furthermore, we derive GQAIDS elasticity formulas, and estimate income elasticities without restrictions. The results partially support the hypothesis that an average Chinese household has incorporated elements of Western diet (fine grains) into traditional Chinese food diet over time. Moreover, the outcome of a simple test developed here points to possible preference changes for a majority of food staples under study. [ABSTRACT FROM AUTHOR]

Abstract: Helicoverpa armigera (Hübner) (Lepidoptera: Noctuidae) is a serious pest of cotton and many other crops in northern China. To evaluate the contribution of alternative hosts as an effective refuge for transgenic cotton expressing the Bacillus thuringiensis (Bt) Cry1Ac toxin, the susceptibility to this toxin was measured in progeny derived from field-collected H. armigera larvae and pupae from different hosts in the Xiajin’s region of the Shandong Province in northern China. During 2008–2010, progeny from a total of 258,56,184 and 160 single-pair crosses derived from wheat (first-generation), Bt cotton (second-generation), Bt cotton (third-generation), and corn (third-generation) were screened on Cry1Ac diets, respectively. Based on relative average development rates (RADR) of H. armigera larvae in these F1 tests, the second and third-generation moths emerging from Bt cotton fields were more tolerant to the Bt toxin than the first and third-generation moths emerging from wheat and corn each year. These results suggest that there is significant variation in susceptibility to Bt toxins among H. armigera populations derived from different host crops. Alternate crops, such as corn, that maintain Bt susceptible populations of H. armigera could be used as refugia to minimize the evolution of resistance to Bt cotton. [Copyright &y& Elsevier]

It further informs that A. planipennis is a pest of Fraximus velutina (F. velutina), velvet as plant in China, which has caused plantation damage after being accidentally introduced in North America. It also presents photographic images of the life stages and behavior of S. agrili.

Helicouerpa armigcra is an important lepidopteran pest of cotton in China. From 2002, the frequency of Bt resistance alleles and quantitative shifts in larval CrylAc tolerance of field H. arinigera population were monitored using bioassays of F1 and F2 offspring of isofemale lines from Xiajin County of Shandong Province (an intensive Bt cotton planting area) and Anci County of Hebei Province (a multiple-crop system including corn, soybean, peanut, and Bt cotton) in northern China. During 2006-2008, a total of 2,306 isofemale lines from the Xiajin population and a total of 1,270 isofemale lines from the Anci population were successfully screened on CrylAc diets. For each year, it was estimated that the major resistance gene frequency in Xiajin population in 2006,2007, and 2008 was 0,0.00022, and 0.00033, respectively. No major alleles conferring resistance to CrylAc were found in the Anci population; the frequency of resistance alleles for CrylAc was 0. Based on the relative average development rates (RADRs) of H. armigera larvae in F1 tests, no substantial increase in CrylAc tolerance was found in either location over the 3-yr period. There were also significantly positive correlations between RADR of lines in the F1 generation and the RADR of their F2 offspring, indicating genetic variation in response to toxin. The low frequency of resistance alleles found in this study and in our previous results from 2002 to 2005 suggest the frequency of resistance alleles has remained low and that natural refugia resistance management strategy maybe effective for delaying resistance evolution in H. armigera to Bt cotton in northern China.

Helicoverpa armigera (Hübner) (Lepidoptera: Noctuidae) is an important lepidopteran pest of cotton, Gossypium hirsutum L., in Asia. Transgenic cotton expressing the cry1Ac gene from Bacillus thuringiensis (Bt) has been widely planted for control of this pest. For managing the potential risk from resistance evolution in this pest, a new transgenic Bt cotton containing cry1Ac and cry2Ab genes (gene pyramided strategy) was designed as a successor of cry1Ac cotton. This article reports on levels of Cry2Ab tolerance in H. armigera populations from Cry1Ac cotton planting region in China based on bioassays of F1 and F2 offspring of isofemale lines. In total, 572 isofemale families of H. annigera from Xiajin County of Shandong Province (an intensive Bt cotton-planting area) and 124 families from Anci County of Hebei Province [a multiple-crop system, including corn (Zea mays L.), soybean (Gycine max (L.) Merr., peanut (Arachis spp.), and Bt cotton] were screened with both Cry1Ac- and Cry2Ab-containing diets in 2008. The bioassays results indicated that relative average development rates (BADR) of F1 full-sib families from field-collected female moths on Cry1Ac- and Cry2Ab-containing diet were positively correlated. The same correlation was found in the F2 generation, indicating cross-tolerance between Cry1Ac and Cry2Ab in field populations of H. armigera in Yellow River cotton-farming region of China. This cross-tolerance must be considered in evaluating the utility of pyramiding Bt genes in cotton for delaying evolution of resistance. [ABSTRACT FROM AUTHOR]

1. Changes in the frequency of Cry1Ac resistance genes and shifts in tolerance of cotton bollworm, Helicoverpa armigera, to the Cry1Ac toxin were assessed using bioassays of F1 and F2 offspring of isofemale lines from Anci County of Hebei Province (a multiple-crop system including corn, soybean, peanut, and Bt cotton) and Xiajin County of Shandong Province (an intensive Bt cotton planting area) in Northern China during 2002–2005. 2. A conservative analysis of the overall results indicated that there was a small increase in the frequency of major, non-recessive resistance genes over time. 3. The relative average development ratings [RADR – growth rate of a line on a Bt diet in proportion to the growth rate on a non-Bt (NBT) diet] of the bollworm larvae in F1 tests increased significantly from year to year, indicating a gradual trend towards higher tolerance to Cry1Ac in the field populations. 4. There were also significant positive correlations between RADR of the lines in the F1 generation and the RADR of their F2 offspring, indicating that the tolerance was genetically based. 5. Quantitative genetic simulation analysis showed that resistance of H. armigera to Bt cotton in Xiajin could evolve to a high level in 11–15 years if no effective resistance management measures are carried out.

We evaluate the current structure of food demand in urban China by using household expenditure survey data from five provinces. Two complementary analyses are undertaken. First, an aggregate analysis based on a fractional logit model is used to examine how households allocate food expenditures across the food-at-home (FAH) and food-away-from-home (FAFH) categories. This is followed by a disaggregated analysis of how households allocated their FAH expenditures across 12 commodity categories. A Quadratic Almost Ideal Demand System (QUAIDS) is used. We find evidence of significant food purchase substitution and complementarity. [ABSTRACT FROM AUTHOR]

This article presents the results of a demonstration project of priority setting by clinicians in Hong Kong's public hospitals. Thirty-five chiefs-of-service of public hospitals in Hong Kong participated in a three-round Delphi exercise on identifying interventions that should be charged in public hospitals on the basis of questionable effectiveness and other reasons. A total of 246 interventions were identified in the first round, 126 of which received a positive score (indicating a high degree of consensus amongst the participants) at the end of the final round. The interventions that received higher scores tend to be preventive services, treatment of an elective nature, and procedures for sex-related conditions. As the number of interventions with positive scores in the final round are relatively small, the amount of money to be recovered from charging these interventions is not likely to be substantial. Such results suggest that rationing by itself cannot be a solution to the problems of healthcare financing in Hong Kong. [ABSTRACT FROM AUTHOR]

The yellow spotted stink bug (YSSB), Erthesina fullo Thunberg, is one of the most widely distributed phytophagous insect pests in Asia. YSSB is highly polyphagous and in China it feeds on over 57 host plants in 29 families, including some economically important fruit crops such as kiwifruit, pear, peach, apple, and pomegranate. With a primarily r-selected life history strategy, reproductive diapause, aggregation behavior, wide host range, high dispersal capacity, and close association with human-modified ecosystems, YSSB is a potentially invasive species that poses significant biosecurity threats to other countries outside its native range. This review summarizes basic and applied knowledge on the biology, ecology, and management of YSSB in China, with specific emphasis on its life history, host range, damage and impacts on economically important horticulture crops, and integrated pest management (IPM) approaches. The insights from the Chinese literature on this pest will help the countries outside its native range to conduct appropriate biosecurity risk assessments, develop a sound surveillance program, and develop an emergency response plan before its invasion of new geographic areas.

Worldwide, massive amounts of food waste have been generated at increasingly accelerated rates, posing potentially great risks to the environment. Shifting traditional waste treatment to a sustainable bioeconomy thus challenges food chain management worldwide. In this study, food waste was copyrolyzed with rice husk to produce biochar with a pilot-scale industrialized system. The efficiency of the material conversion and the properties and functions of the produced biochars as well as the potential environmental impacts of pyrolysis were evaluated using in situ measurements, physico-chemical characterization and in vitro (pot) experiments with biochar. The results showed that the emissions of potential toxic compounds and metals from the pyrolysis system were within the guideline limits under the legislation of China or the EU commission. On average, biochar yielded approximately 20% of feedstock and contained a total organic carbon content of 433 g kg−1. In the pot experiment, Chinese cabbage yield and quality were significantly improved, and the plant uptake of heavy metals was significantly reduced in soil amended with food waste biochar compared to no biochar amendment. Furthermore, the food waste biochar was blended with mineral nutrients to create a biochar based compounded N-P-K fertilizer. Application of the biochar based compound fertilizer exerted a significant positive effect on cabbage growth and nutrient use efficiency relative to a conventional mineral compound fertilizer. For per tonne of dry mass of food waste, copyrolysis costed less than 60 USD but gained a gross profit of more than 30 USD. Therefore, the copyrolysis of food waste with crop residues could be applicable to the safe recycling of food waste into value added products to raise agricultural production. [Display omitted] • A pilot-scale copyrolysis system was used to convert food waste into biochar. • The concentrations of potential toxic elements in flue gas was negligible. • Food waste biochar (BC) and biochar compound fertilizer (BCF) was analyzed. • BC and BCF significantly improved the yield and quality of Chinese cabbage. • The average cost and gross profit were 54.5 and 32.9 USD per tonne.

Objectives: In December 2019, a pneumonia-like illness was first reported in Wuhan-China caused by a new coronavirus named corona virus disease-2019 (COVID-19) which then spread to cause a global pandemic. Most of the available data in the literature is derived from Chinese cohorts and we aim to contribute the clinical experience of a single British clinical centre with the characteristics of a British cohort., Design: A prospective case series., Setting: A single clinical centre in the UK., Methods: We have collected the demographics and medical characteristics of all COVID-19-positive cases admitted over 2-week period. All cases were diagnosed by PCR., Results: Total of 71 COVID-19 patients were included in this case series. Majority of patients (75%) were ≥75 years old and 58% were men. Pre-existing comorbidities was common (85% of patients). Most patients presented with respiratory symptoms such as fever (59%), shortness of breath (56%) and cough (55%). Gastrointestinal symptoms were second-most common presenting compliant such as diarrhoea (10%) and abdominal pain (7%). Opacification in chest X-rays was demonstrated in 45% of patients. All patients received supportive treatment and no specific antiviral therapy was administered in this cohort. So far, 18 (25%) patients have fully recovered, 9 patients (13%) escalated to a higher level of care and 10 (14%) have died. Patients who died were non-significantly older than those who have recovered (78.0 vs 69.2 years, P = .15) but they had a significantly higher clinical frailty scores (5.75 vs 3.36, P = .005)., Conclusion: This case series demonstrated that the characteristics of British COVID-19 patients were generally similar to what is published in literature, although we report more gastrointestinal symptoms at presentation. We have identified frailty as a risk factor for adverse outcome in COVID-19 patients and suggest that it should be included in the future vaccination recommendations., (© 2020 John Wiley & Sons Ltd.)
