Panic buying research: A systematic literature review and future research agenda
Authors: Billore Soniya , Anisimova Tatiana 
Published: March 2021

AbstractPanic buying has re‐emerged as a ‘new’ normal consumer behaviour and has become a coping mechanism for real and perceived dangers associated with COVID‐19. Despite the need for a better understanding of the panic buying phenomenon, there has been a lack of scholarly research on this topic. This study seeks to fill this gap. In this article, we systematically review extant studies in panic buying from the last two decades. We analyse and categorize them according to Callahan's 4W (2014) review structure and Paul and Rosado‐Serrano's (2019) TCCM framework. We found that the existing publications in panic buying are fragmented across multiple disciplines. Due to the nature of the panic‐induced behaviour, most of them have been written as a reaction to the pandemic crisis. We contribute to marketing research by providing theoretical, contextual and methodological insights into the field of panic buying. Furthermore, we develop a research agenda related to retailer and consumer perspectives. Additionally, we identify research issues related to policymaking and governance, as well as broader societal impacts that need to be addressed in the future.

AbstractIn contrast to humans or rabbits, in which maternal IgG is transmitted to offspring prenatally via the placenta or the yolk sac, large domestic animals such as pigs, cows and sheep transmit IgG exclusively through colostrum feeding after delivery. The extremely high IgG content in colostrum is absorbed by newborns via the small intestine. Although it is widely accepted that the neonatal Fc receptor, FcRn, is the receptor mediating IgG transfer across both the placenta and small intestine, it remains unclear whether FcRn also mediates serum IgG transfer across the mammary barrier to colostrum/milk, especially in large domestic animals. In this study, using a FcRn knockout pig model generated with a CRISPR‐Cas9‐based approach, we clearly demonstrate that FcRn is not responsible for the IgG transfer from serum to colostrum in pigs, although like in other mammals, it is involved in IgG homeostasis and mediates IgG absorption in the small intestine of newborns.
Extension of social insurance coverage to informal economy workers in China: An administrative and institutional perspective
Authors: Qian Jiwei , Wen Zhuoyi 
Published: March 2021

AbstractThis article reviews administrative issues in the context of decentralized social protection in China. In particular, what are the main obstacles to expanding social insurance coverage for workers in the informal economy? Over the last two decades, China has achieved remarkable progress toward universal social protection when this target was set as a national policy priority. However, the social insurance enrolment of informal economy workers still lags significantly behind. This article reviews the application of the International Labour Organization’s definition of informality in the Chinese context and overviews existing pension and health insurances in China. This article discusses the impact of China’s inter‐governmental fiscal relations and decentralized social protection in the multilevel government system. The article highlights that under a system of decentralized managed social insurance many informal economy workers choose to opt out of the system because of low benefits and high compliance costs. This result in deficits in social insurance coverage amongst informal economy workers.

Published: March 2021

AbstractThis article reports the results of our work to construct a system for the detection of fraudulent behavior in procurement transactions. To solve the problem, we model different types of fraud via separate statistical indicators. We propose a formalized framework to describe the severity of fraud in a unified way regardless of underlying fraud mechanics. Subsequently, we leverage this concept to build indicator ensembles that collect evidence from multiple indicators and deliver an interpretable per transaction score to the procurement audit officer. As a case study, we overview 48 such fraud indicators constructed for our client and describe two examples in detail showing how our formal definitions can be transformed into a practical implementation. The presented results include experiments with all indicators on data covering four years of procurement activity with approximately 216,000 transactions coming from a large government organization in Singapore. The final evaluation of our system shows 67.1% precision in detecting suspicious transactions. The article describes how outcome of our work helped to effectively cope with the problem of anomaly detection explainability and the lessons learned from integrating this solution to operational practices of a procurement department.

AbstractStriae distensae, also known as stretch marks, particularly associated with female sex, pregnancy, obesity, and/or hormonal change, are linear bands of benign dermal lesions. Although not posing any health risk, aesthetically unpleasing stretch marks can cause significant psychological distress among those affected. In abundance of therapeutic approaches, some literature sources proclaim platelet‐rich plasma to be a promising treatment modality for striae distensae. We aimed to shed some light on the current literature evidence of platelet‐rich plasma for treating stretch marks and performed an English literature analysis with two independent reviewers in accordance with PRISMA guidelines searching the PubMed and Web of Science databases in June 2019. Of the 12 found studies, 6 matched inclusion criteria. With no control groups in two, just two other reports used intraindividual comparisons, and all but one publication performed histopathological assessments. All studies observed clinical and subjective improvements without using validated scores or patient‐reported outcome measures (PROMs). The main findings were that multiple treatments with platelet‐rich plasma demonstrated increased epidermal thickness, rete ridges formation, and collagen/elastin formation, while decreasing the inflammatory cell infiltrate. The current literature evidence supporting the use of platelet‐rich plasma for striae distensae is poor. We propose in this review an outline for a study protocol with intraindividual control groups, standardised scores, validated PROMs, and participant incentives to enhance the scientific power in future clinical trials.
Modified compression therapy in mixed arterial–venous leg ulcers: An integrative review
Authors: Lim Sheryl Li Xin , Chung Rui En , Holloway Samantha , Harding Keith G. 
Published: March 2021

AbstractLeg ulcers remain an increased burden to healthcare cost and morbidity in modern society. While most leg ulcers are venous in origin, recognition and prompt identification of concomitant arterial occlusive disease is critical to determine underlying aetiology and subsequent management. This integrative review presents the current evidence to establish the role of modified compression therapy (MCT) in treatment of mixed arterial venous leg ulcers (MAVLU). A literature search was conducted using the electronic databases CINAHL, MEDLINE, PUBMED, and Embase. Ten studies met the eligibility criteria and were subsequently analysed. Our review concludes that MCT, with compression pressures between 20 and 30 mmHg, can promote healing in MAVLU with moderate arterial insufficiency (0.5 ≤ ABPI ≤0.8). If ABPI is <0.5, MCT can be considered once restoration of acceptable ABPI is achieved. Intolerance, lack of response or further deterioration of disease within 3 months should prompt further arterial imaging and intervention. MCT is generally well tolerated with no adverse outcomes reported. A holistic yet individualised approach is vital in order to account for all factors influencing this patient‐led decision‐making process, ultimately ensuring effective treatment, which improves patient's quality of life and reduces socioeconomic burden of the disease.

AbstractIntroductionHypothermia is common in trauma patients. It contributes to increasing mortality rate. Hypothermia is multifactorial, favoured by exposure to cold, severity of the patient's state and interventions such as infusion of fluids at room temperature.AimTo demonstrate that specific management of hypothermia (or of the risk of hypothermia) increases the number of trauma patients arriving at the hospital with a temperature >35°C.DesignThis is a prospective, multicentre, open‐label, pragmatic, cluster randomized clinical trial of an expected 1,200 trauma patients included by 12 out‐of‐hospital mobile intensive care units (MICU). Trauma patients are included in a prehospital setting if they present at least one of the following criteria known to be associated with an increased incidence of hypothermia: ambient temperature <18°C, Glasgow coma scale <15, systolic arterial blood pressure <100 mm Hg or body temperature <35°C. Patients are randomized, by cluster, to receive a conventional management or ‘interventional’ nursing management associating: continuous epitympanic temperature monitoring, early installation in the heated ambulance (temperature target >30°C controlled by infrared thermometer), protection by a survival blanket, and use of heated solutes (temperature objective >35°C controlled by infrared thermometer). The primary end point is the prevalence of hypothermia on arrival at the hospital. The hypothesis tested is a reduction from 20% to 13% in the prevalence of hypothermia. Secondary end points are to evaluate the interaction between the effectiveness of the measures taken and: (1) the severity of the patients assessed by the Revised Trauma Score; (2) the meteorological conditions when they are managed; (3) the time of care; and (4) therapeutic interventions.DiscussionThis trial will assess the effectiveness of an invasive, out‐of‐hospital, temperature management on the onset of hypothermia in moderate to severe trauma patients.ImpactSpecific management of hypothermia is expected to decrease hypothermia in trauma patients.
Inequality, autocracy, and sovereign funds as determinants of foreign portfolio equity flows
Authors: Kemme David M. , Parikh Bhavik , Steigner Tanja 
Published: March 2021

AbstractWe identify new country characteristics that influence cross‐border equity flows: income inequality, autocracy, and sovereign wealth funds. Using 149 source countries and 34 Organisation for Economic Co‐operation and Development (OECD) host countries for 2002–2013, we find that OECD host countries receive higher foreign portfolio investment (FPI) inflows from source countries with high income inequality and source countries with a sovereign wealth fund, but lower inflows from autocratic source countries. We argue that concentrated wealth in a society, overseas investments for the benefit of future generations, and political regimes influence FPI. These variables have been understudied though they provide valuable indicators for policy makers and investors. We supplement our core analysis with realistic interactions between these new variables and with the increasing importance of tax havens. Our results hold throughout a variety of robustness checks.
Alternative freezing: Effects on rehydration properties of freeze‐dried daikon (Raphanus sativusL.)

Published: March 2021

AbstractFreeze‐drying of daikon was performed using four different freezing conditions: two processes at constant temperature (−20 and −30°C—conventional); and two alternative approaches (dynamic and variable by levels). Freezing rates were evaluated and all methods achieved commercial freezing requirements (10–50°C hr−1). The two modified processes presented similar freezing rates to the conventional operation; moreover, evidence was found to consider these two processes statistically equivalent. Then, freeze‐dried samples were rehydrated by immersion in distilled water, and rehydration kinetic curves were adjusted to semi‐empirical models; the Weibull model presented the best fit. Finally, rehydration quality parameters of the samples were evaluated. The dynamic freezing process showed the best rehydration quality, while the variable by levels showed the closest results to the conventional one. In conclusion, these results indicate a technologically attractive improvement as an alternative for traditional industrial processes.Practical ApplicationsA new freezing methodology was proposed, which consists of changing the freezing operating conditions, considering the product temperature throughout the process. Such an operation provides high‐quality freeze‐dried products, regarding rehydration properties. The procedure can be used in the replacement of conventional freezing, resulting in better freeze‐dried products.
Too little, too late: Palliation and end‐stage liver disease

Published: March 2021

AbstractBackground and AimEnd‐stage liver disease is a leading cause of mortality. Fewer than 60% of patients with decompensated cirrhosis survive after 2 years, with patients often experiencing distressing symptoms impairing quality of life. Early advanced care planning and timely palliative care referral can improve quality of life and the end of life experience. We aimed to determine palliative care referral rates and patterns for patients admitted with decompensated cirrhosis, and to identify the factors associated with referral.MethodsThis was a retrospective, single‐center study undertaken at a metropolitan tertiary referral hospital. Patients admitted between the 1 June 2016 and 31 January 2019 with a Child–Pugh score of B or C, and a model for end‐stage liver disease score ≥ 15 were included. We assessed survival and compared those referred and not referred to palliative care, adjusting for lag‐time to referral (Kaplan–Meier analysis).ResultsOne‐hundred and sixteen admissions met eligibility criteria for referral. The median age at admission was 59 years, with 76% male participants. Only a fifth of eligible patients (25/116) were referred to palliative care. The median survival (from referral) for those referred to palliative care was 20 days, versus 148 days for those not referred.ConclusionsDespite benefits from timely referral, less than one quarter of palliative care eligible patients was referred. Referral appears reserved for those facing imminent death—surviving just under 3 weeks postreferral, yet mortality in nonreferred patients remained high (148‐day median). Low rates and late referral are a missed opportunity to improve the end of life care for patients with end‐stage liver disease.

AbstractBackground/ObjectivesDifferences in older adults' worry, attitudes, and mental health between high‐income countries with diverging pandemic responses are largely unknown. We compared COVID‐19 worry, attitudes towards governmental responses, and self‐reported mental health symptoms among adults aged ≥55 in the United States and Canada early in the COVID‐19 pandemic.DesignOnline cross‐sectional survey administered between April 2nd and May 31st in the United States and between May 1st and June 30th, 2020 in Canada.SettingNationally in the United States and Canada.ParticipantsConvenience sample of older adults aged ≥55.MeasurementsLikert‐type scales measured COVID‐19 worry and attitudes towards government support. Three standardized scales assessed mental health symptoms: the eight‐item Center for Epidemiological Studies Depression Scale, the five‐item Beck Anxiety Inventory, and the three‐item UCLA loneliness scale.ResultsThere were 4453 U.S. respondents (71.7% women; mean age 67.5) and 1549 Canadian (67.6% women; mean age 69.3). More U.S. respondents (71%) were moderately or extremely worried about the pandemic, compared to 52% in Canada. Just 20% of U.S. respondents agreed or strongly agreed that the federal government cared about older adults in their COVID‐19 pandemic response, compared to nearly two‐thirds of Canadians (63%). U.S. respondents were more likely to report elevated depressive and anxiety symptoms compared to Canadians; 34.2% (32.8–35.6) versus 25.6% (23.3–27.8) for depressive and 30.8% (29.5–32.2) versus 23.7% (21.6–25.9) for anxiety symptoms. The proportion of United States and Canadian respondents who reported loneliness was similar. A greater proportion of women compared to men reported symptoms of depression and anxiety across all age groups in both countries.ConclusionU.S. older adults felt less supported by their federal government and had elevated depressive and anxiety symptoms compared to older adults in Canada during early months of the COVID‐19 pandemic. Public health messaging from governments should be clear, consistent, and incorporate support for mental health.
“You helped me out of that darkness” Children as dialogical partners in the collaborative post‐family therapy research interview
Authors: Helimäki Mira , Laitila Aarno , Kumpulainen Kirsti 
Published: March 2021

AbstractApplying Dialogical Methods for Investigations of Happening of Change (DIHC), this study investigated how children who had been diagnosed with an oppositional defiant or conduct disorder participated in a collaborative post‐therapy research interview and talked about their experiences of family therapy. The results showed that the children participated as dialogical partners talking in genuine, emotional, and reflective ways. Encountered as full‐membership partners, the children also co‐constructed meanings for their sensitive experiences. However, their verbal initiatives and responses appeared in very brief moments and could easily have been missed. The collaborative post‐therapy interview offered a safe forum for co‐reflection by participants on what they had found useful or difficult in the family therapy process. In this interview setting, the family first listens to reflection by the therapists on the therapy process and their thoughts on some of the family's related sensitive issues. The results indicate that when therapists present themselves as not‐knowing, receptive and accountable, therapists may facilitate reflection for all family members, including children.
Perspectives on mental health recovery from Egyptian mental health professionals: A qualitative study
Authors: Ibrahim Nashwa , Ghallab Eman , Ng Fiona , Eweida Rasha , Slade Mike 
Published: March 2021

Accessible SummaryWhat is known on the subject?

Personal recovery concept is dominant in mental health systems when service user involvement is emphasized; however, service user involvement in mental health research and practice does not exist in Egypt.

Definitions of recovery from high‐income and English‐speaking countries should be carefully adapted to other settings.

Nurses providing mental health care in Egypt generally do not have specialized mental health nursing qualifications.

What the paper adds to existing knowledge?

Both cultural and contextual uniqueness of Egypt as a Middle Eastern, low‐middle‐income country were clear in the findings of this paper.

There are differences in the definition of family and service user engagement in the current study and in high‐income countries.

Seeking faith healers as a barrier to mental health recovery is culturally unique.

Functional recovery prevails as a model in Egypt as there is limited service user involvement.

Nursing values and code of ethics are consistent with enablers of mental health recovery.

What are the implications for practice?

Changing the pre‐registration nursing education to prepare specialized graduates in mental health nursing.

Training of mental health professionals on recovery approaches which involve service users is needed in Egypt. Mental health nurses in Egypt can use the current findings to implement national campaigns to raise public awareness of mental health problems.

AbstractIntroductionRecovery‐oriented mental health practice is an emerging approach that aims to empower individuals to define their goals and take responsibility for their own recovery. However, mental health practice in Egypt is still custodial.AimTo explore perspectives of Egyptian mental health professionals on recovery.MethodSemi‐structured interviews were conducted with 15 mental health professionals identified through snowball sampling.ResultsThe current study identified that functional recovery outweighed other definitions. Four facilitators of mental health recovery were identified: therapeutic relationship; family engagement; cultural sensitivity; and professionals’ self‐awareness. Six barriers to recovery were found, comprising mental health stigma and lack of awareness, seeking traditional healers, shortage of psychiatrists, cost of treatment, lack of training and effective rehabilitation programs.DiscussionThe concept of functional recovery predominates among nurses and other mental health professionals, which may be due to limited training and the historical lack of service user involvement in Egypt. Lack of support from family and society, inadequate training MHPs and perceived system inefficiencies are also major impeding factors for recovery.Implications for PracticeThere is a need for nurses to be involved in designing intervention programs targeting the general public and to support increased involvement of people with mental health issues.
