High-energy focused extracorporeal shock wave prevents the occurrence of glucocorticoid-induced osteonecrosis of the femoral head: A prospective randomized controlled trial. J Orthop Translat 2022; 36:145-151. [PMID: 36263382 PMCID: PMC9550842 DOI: 10.1016/j.jot.2022.08.002] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/02/2022] [Revised: 07/28/2022] [Accepted: 08/03/2022] [Indexed: 11/06/2022] Open
Abstract
Background Studies have shown that high-energy focused extracorporeal shock wave therapy (HF-ESWT) has a certain therapeutic effect on glucocorticoid-induced osteonecrosis of the femoral head (ONFH). This study aimed to observe the efficacy and safety of HF-ESWT as a precautionary measure to reduce the probability of glucocorticoid-induced ONFH. Methods A prospective randomized controlled trial was designed to evaluate whether HF-ESWT (Group A) can significantly prevent the incidence of glucocorticoid-induced ONFH relative to a control group without shockwave intervention (Group B). MRI was used to assess whether all participants experienced ONFH at 3, 6, and 12 months after the intervention. Continuous scoring was used to evaluate the intervention results: the 10-cm visual analog scale (VAS) was used to evaluate pain, and the hip Harris score (HHS) was used to evaluate the function of the hip joint. Any adverse events were recorded. Results 153 patients (89 females and 64 males) who had been allocated to group A (75 patients) or Group B (78 patients) were included in the final analysis. The patients were 45.0 ± 13.0 years old. There were significant differences between the two groups in MRI diagnosis of ONFH patients (2 cases in Group A, 9 cases in Group B; p = 0.034). Significant differences between groups were found in bilateral hip function measured using the HHS at 6 months (Left p = 0.026; Right p = 0.033) and 12 months (Left p = 0.018; Right p = 0.038). However, there was no difference in the functional results measured at 3 months and the VAS at any points. Conclusions This study confirms that HF-ESWT can be successfully used to reduce the probability of glucocorticoid-induced ONFH. Pain and hip dysfunction are common clinical manifestations when ONFH is unavoidable. Therefore, HF-ESWT can be recommended for the prevention and intervention of ONFH high-risk populations receiving high-dose glucocorticoid therapy. The Translational potential of this article The effective prevention of HF-ESWT on ONFH after high-dose glucocorticoid application demonstrated its transformation potential as a preventive method in the clinical prevention of glucocorticoid-induced ONFH.

Abstract
INTRODUCTION This study aims to determine whether ESWT (extracorporeal shock wave therapy) affects ONFH (osteonecrosis of femoral head) in clinical outcomes and radiography outcomes. METHOD Two authors independently search the papers on the treatment of femoral head necrosis with extracorporeal shock wave in CNKI (China National Knowledge Infrastructure), VIP (China Science and Technology Journal Database), CSPD (China Science Periodical Database), Pubmed, Embase, and Springer databases. Search period from the inception dates to 2 June 2020 and have no limitations in language; two authors independently conducted a quality evaluation and data extraction for included studies and performed a meta-analysis with data extracted and calculate by using RevMan5. Registration number: CRD42020213580. RESULT Nine articles with 409 patients are included in this meta-analysis. The pooled results of HHS (Harris hip score) in eight studies with 337 hips show that ESWT achieves higher Harris scores compared to before treatment (MD = -19.95; 95% CI: -26.27, -13.64) and the difference is statistically significant (p < 0.01). The pooled results of VAS (visual analogue score) in seven studies with 253 hips show that ESWT achieves lower VAS compared to baseline (MD = 2.77; 95% CI: 1.88, 3.65) and the difference is statistically significant (p < 0.01). The pooled results of lesion of MRI with 164 hips show that ESWT decreases the lesion area of MRI (SMD = 1.03; CI: 0.75,1.30) and the difference is statistically significant (p < 0.01). CONCLUSION ESWT has an effect on pain relief and has a limited effect on motion function. Its effect may be better than surgical groups (core decompression and core decompression with bone grafting). But it cannot decrease the lesion area of the femoral head on MRI and stop disease progression.

Abstract
AIMS This study aimed to describe the experiences of nurses and other health care workers who were infected with coronavirus disease 2019. METHODS An empirical phenomenological approach was used. Sixteen participants were recruited in Wuhan using purposive and snowball sampling. Semistructured, in-depth interviews were conducted by telephone in February 2020. Interviews were transcribed verbatim and analysed following Colaizzi's method. RESULTS Two themes emerged: (1) Intense emotional distress since becoming infected. Participants were fearful of spreading the virus to family and overwhelmed by a lack of information, experienced uncertainty and worried about treatment, felt lonely during isolation and reported moral distress about inadequate health care staffing. (2) Coping strategies were needed. They tried their best to address negative psychological reactions using their professional knowledge and gaining support from others and community resources. CONCLUSIONS Preparedness for catastrophic events and providing timely and accurate information are major considerations in government policy development, related to pandemics and adequacy of health care personnel. Mental health resources and support, both short- and long-term should be anticipated for health care providers to alleviate their fear and anxiety.

Abstract
Summary The recent outbreak of coronavirus disease 2019 (COVID-19) has become a global epidemic. Corticosteroids have been widely used in the treatment of severe acute respiratory syndrome (SARS), and the pathological findings seen in severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection are very similar to those observed in severe acute respiratory syndrome-related coronavirus (SARS-CoV) infection. However, the long-term use of corticosteroids (especially at high doses) is associated with potentially serious adverse events, particularly steroid-induced avascular necrosis of the femoral head (SANFH). In today’s global outbreak, whether corticosteroid therapy should be used, the dosage and duration of treatment, and ways for the prevention, early detection, and timely intervention of SANFH are some important issues that need to be addressed. This review aims to provide a reference for health care providers in COVID-19 endemic countries and regions. Article Focus Hormones are a double-edged sword. This review aims to provide a reference for health care providers in coronavirus disease 2019 (COVID-19) endemic countries and regions, especially with respect to the pros and cons of corticosteroid use in the treatment of patients with COVID-19. Key Messages In today’s global outbreak, whether corticosteroid therapy should be used, the dosage and duration of treatment, and ways for the prevention, early detection, and timely intervention of SANFH are some important issues that need to be addressed. Strengths and Limitations Since SARS was mainly prevalent in China at that time, many evidences in this paper came from the reports of Chinese scholars. There is a bias in the selection of data, which may ignore the differences in environment, race, living habits, medical level and so on. SANFH may be the result of multiple factors. Whether the virus itself is an independent risk factor for SANFH has not been confirmed. In this paper, through literature retrieval, some reference opinions on glucocorticoid usage, diagnosis and treatment of SANFH are given. However, due to the lack of large-scale research data support, it can not be used as the gold standard for the above problems.

Abstract
BACKGROUND Immune-mediated lung injury and systemic hyperinflammation are characteristic of severe and critical coronavirus disease 2019 (COVID-19) in adults. Although the majority of severe acute respiratory syndrome coronavirus 2 infections in pediatric populations result in minimal or mild COVID-19 in the acute phase of infection, a small subset of children develop severe and even critical disease in this phase with concomitant inflammation that may benefit from immunomodulation. Therefore, guidance is needed regarding immunomodulatory therapies in the setting of acute pediatric COVID-19. This document does not provide guidance regarding the recently emergent multisystem inflammatory syndrome in children (MIS-C). METHODS A multidisciplinary panel of pediatric subspecialty physicians and pharmacists with expertise in infectious diseases, rheumatology, hematology/oncology, and critical care medicine was convened. Guidance statements were developed based on best available evidence and expert opinion. RESULTS The panel devised a framework for considering the use of immunomodulatory therapy based on an assessment of clinical disease severity and degree of multiorgan involvement combined with evidence of hyperinflammation. Additionally, the known rationale for consideration of each immunomodulatory approach and the associated risks and benefits was summarized. CONCLUSIONS Immunomodulatory therapy is not recommended for the majority of pediatric patients, who typically develop mild or moderate COVID-19. For children with severe or critical illness, the use of immunomodulatory agents may be beneficial. The risks and benefits of such therapies are variable and should be evaluated on a case-by-case basis with input from appropriate specialty services. When available, the panel strongly favors immunomodulatory agent use within the context of clinical trials. The framework presented herein offers an approach to decision-making regarding immunomodulatory therapy for severe or critical pediatric COVID-19 and is informed by currently available data, while awaiting results of placebo-controlled randomized clinical trials.

Abstract
Corona pandemic has affected the whole world, and it is a highly researched area in biological sciences. As the current pandemic has affected countries socially and economically, the purpose of this bibliometric analysis is to provide a holistic review of the corona pandemic in the field of social sciences. This study aims to highlight significant, influential aspects, research streams, and themes. We have reviewed 395 journal articles related to coronavirus in the field of social sciences from 2003 to 2020. We have deployed 'biblioshiny' a web-interface of the 'bibliometrix 3.0' package of R-studio to conduct bibliometric analysis and visualization. In the field of social sciences, we have reported influential aspects of coronavirus literature. We have found that the 'Morbidity and Mortality Weekly Report' is the top journal. The core article of coronavirus literature is 'Guidelines for preventing health-care-associated pneumonia'. The most commonly used word, in titles, abstracts, author's keywords, and keywords plus, is 'SARS'. Top affiliation is 'The University of Hong Kong'. Hong Kong is a leading country based on citations, and the USA is on top based on total publications. We have used a conceptual framework to identify potential research streams and themes in coronavirus literature. Four research streams are found by deploying a co-occurrence network. These research streams are 'Social and economic effects of epidemic disease', 'Infectious disease calamities and control', 'Outbreak of COVID 19,' and 'Infectious diseases and the role of international organizations'. Finally, a thematic map is used to provide a holistic understanding by dividing significant themes into basic or transversal, emerging or declining, motor, highly developed, but isolated themes. These themes and subthemes have proposed future directions and critical areas of research.

Abstract
Objective To study the role of primary cilia formation disorder and osteoblasts autophagy in the pathogenesis of steroid‐induced avascular necrosis of the femoral head (SANFH). Methods Osteoblasts were isolated from rabbit bones and treated with 1 μM Methylprednisolone for 0, 12, 24, 48, and 72 h. The Beclin1, MAP1LC3, Atg‐5, Atg‐12, IFT20 and OFD1 mRNAs and proteins were detected by PCR and Western blotting, and their correlation was statistically analyzed. The lengths of osteoblast cilia were measured under a laser confocal microscope, and the autophagy flux was tracked by transfecting the osteoblasts with GFP‐RFP‐LC3 lentivirus. Results Methylprednisolone significantly upregulated Beclin1, MAP1LC3, Atg‐5, Atg‐12 and OFD1 mRNAs and proteins in a time‐dependent manner, and decreased that of IFT20 (P < 0.05). In addition, the autophagy flux in the osteoblasts also increased and the ciliary length decreased in a time‐dependent manner after Methylprednisolone treatment. The length of the cilia were 5.46 ± 0.11 um at 0 h, 4.08 ± 0.09 um at 12 h, 3.07 ± 0.07 um at 24 h, 2.31 ± 0.10 um at 48 h, and finally 1.15 ± 0.04 um at 72 h. Methylprednisolone treatment also affects primary cilium numbers in cultures, for 0 to 72 h. The autophagy regulatory genes, Beclin1, MAP1LC3, Atg‐5 and Atg‐12, were found to be negatively correlated with IFT20, with an average correlation coefficient of −0.81. A negative correlation was also found between OFD1 and IFT20, with an average correlation coefficient of −0.53. Conclusion Methylprednisolone inhibits primary cilia formation and promotes autophagy, which could be the pathological basis of SANFH. The exact regulatory mechanism needs to be further studied in vivo.
