Long COVID symptoms greatly affected to quality of life of patients. Massage is a unique treatment form of alternative medicine that can promote health in various dimensions. From the previous studies, massage has affected to Long COVID mechanism via anti-inflammatory process, immune system enhancing process, and hormone level balancing that related to Long COVID symptoms as well as being able to reduce the symptoms of the long COVID symptoms. The study about the efficacy and safety of massage against Long COVID symptoms is the essential approach to increase the value of massage and develop health services in the future.

Pearls of wisdom from the past 5 years of working in telehealth

Over the past several years the perception of telehealth – and its role in healthcare delivery – has changed dramatically. Previously limited to just a few use cases including low-acuity virtual urgent care and chronic outpatient disease management, telehealth now plays some role in virtually every medical specialty and has seen considerable growth in technologies beyond the simple video visit. In this chapter, we highlight the forces that have driven telehealth's rapid growth and adoption. First, we discuss the evolution of the telehealth landscape in the years leading up to the COVID‐19 pandemic, including increasing consumer demand for virtual services, the emergence of new payment models that promote telehealth use, advancements in technical capabilities, and new structures that enabled reimbursement of digital health activities. Then we cover advancements in telehealth directly related to the pandemic and important considerations for continued growth including provider workflow integration, accessibility and equity, and clarity around reimbursement. Finally, we discuss technological innovations and new modes of care delivery – such as digital therapeutics and virtual-first health plans – that are likely to enhance the sophistication and expand the role of telehealth services over the coming years. © 2023 Elsevier Inc.

SARS-CoV-2 infection (COVID-19) in children.

Since the outbreak in December 2019, the SARS-CoV-2 pandemic virus has been a major public health problem in all countries of the world. The virus is transmitted by inhalation of respiratory droplets from the patient or asymptomatic carrier and is highly contagious. The clinical disease in children is similar to any acute respiratory infection with predominant upper respiratory symptoms, but occasionally can progress to pneumonia with acute respiratory distress syndrome and multiorgan failure. The disease is milder in children than in adults, with low mortality, and it appears that infants and young children have a somewhat more severe clinical course. Diagnosis is made by detecting the virus from respiratory samples (mainly nasopharyngeal and oropharyngeal swabs) using polymerase chain reaction. Treatment is usually symptomatic, and in severe and critical forms, the use of one of the antiviral drugs (lopinavir-ritonavir, remdesivir, hydroxychloroquine) may be consideredCopyright © 2020 Croatian Paediatric Society.

Photodynamic therapy: a new treatment against COVID-19

In 2019, a new coronavirus (COVID-19) was discovered in Wuhan, China, which soon spread all over the world. The main hallmark of the disease includes fever, diarrhea, vomiting, and dry cough with dyspnea in half of the patients and acute respiratory distress syndrome (ARDS). Currently, no definitive treatment or prevention therapy exists for COVID-19 but scientists and researchers all over the world are relentlessly working to understand COVID-19 to discover novel therapeutic tools and vaccines. Today, photodynamic therapy (PDT) has been investigated as a noninvasive therapy for the treatment of this pandemic and was able to increase the healing process with the help of appropriate photosensitizers by targeting the pathogen inside the patient's body.

Use of platelet-rich plasma for COVID-19-related olfactory loss: a randomized controlled trial.

INTRODUCTION: The current study evaluated the use of platelet-rich plasma (PRP), an autologous blood product with supraphysiologic concentrations of growth factors, in the treatment of prolonged coronavirus disease 2019 (COVID-19)-related smell loss. METHODS: This multi-institutional, randomized controlled trial recruited patients with COVID-19 who had objectively measured smell loss (University of Pennsylvania Smell Identification Test [UPSIT] ≤ 33) between 6 and 12 months. Patients were randomized to three intranasal injections of either PRP or sterile saline into their olfactory clefts. The primary outcome measure was change in Sniffin' Sticks score (threshold, discrimination, and identification [TDI]) from baseline. The secondary end point measures included responder rate (achievement of a clinically significant improvement, ≥5.5 points TDI), change in individual TDI olfaction scores, and change in subjective olfaction via a visual analog scale. RESULTS: A total of 35 patients were recruited and 26 completed the study. PRP treatment resulted in a 3.67-point (95% CI: 0.05-7.29, p = 0.047) greater improvement in olfaction compared with the placebo group at 3 months and a higher response rate (57.1% vs 8.3%, odds ratio 12.5 [95% exact bootstrap confidence interval, 2.2-116.7]). There was a greater improvement in smell discrimination following PRP treatment compared with placebo but no difference in smell identification or threshold. There was no difference in subjective scores between PRP and placebo. No adverse effects were reported. CONCLUSION: Olfactory function following COVID-19 can improve spontaneously after 6 months and can improve to a greater extent with PRP injection. These data build on the promise of PRP to be a safe potential treatment option for patients with COVID-19-related smell loss, and larger-powered studies will help further assess its efficacy.

High-Precision Synthesis of RNA-Loaded Lipid Nanoparticles for Biomedical Applications.

The recent development of RNA-based therapeutics in delivering nucleic acids for gene editing and regulating protein translation has led to the effective treatment of various diseases including cancer, inflammatory and genetic disorder, as well as infectious diseases. Among these, lipid nanoparticles (LNP) have emerged as a promising platform for RNA delivery and have shed light by resolving the inherent instability issues of naked RNA and thereby enhancing the therapeutic potency. These LNP consisting of ionizable lipid, helper lipid, cholesterol, and poly(ethylene glycol)-anchored lipid can stably enclose RNA and help them release into the cells' cytosol. Herein, the significant progress made in LNP research starting from the LNP constituents, formulation, and their diverse applications is summarized first. Moreover, the microfluidic methodologies which allow precise assembly of these newly developed constituents to achieve LNP with controllable composition and size, high encapsulation efficiency as well as scalable production are highlighted. Furthermore, a short discussion on current challenges as well as an outlook will be given on emerging approaches to resolving these issues.

Natural therapeutics against SARS CoV2: the potentiality and challenges.

The incidence of the COVID-19 pandemic completely reoriented global socio-economic parameters and human civilization have experienced the worst situation in the recent past. The rapid mutation rates in viruses have continuously been creating emerging variants of concerns (VOCs) which devastated different parts of the world with subsequent waves of infection. Although, series of antiviral drugs and vaccines were formulated but cent percent effectiveness of these drugs is still awaited. Many of these drugs have different side effects which necessitate proper trial before release. Plants are the storehouse of antimicrobial metabolites which have also long been utilized as traditional medicines against different viral infections. Although, proper mechanism of action of these traditional medicines are unknown, they may be a potential source of effective anti-COVID drug for future implications. Advanced bioinformatic applications have opened up a new arena in predicting these repurposed drugs as a potential COVID mitigator. The present review summarizes brief accounts of the corona virus with their possible entry mechanism. This study also tries to classify different possible anti COVID-19 plant-derived metabolites based on their probable mode of action. This review will surely provide useful information on repurposed drugs to combat COVID-19 in this critical situation.

Supramolecular Nanofibers Block SARS-CoV-2 Entry into Human Host Cells.

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection relies on its spike protein binding to angiotensin-converting enzyme 2 (ACE2) on host cells to initiate cellular entry. Blocking the interactions between the spike protein and ACE2 offers promising therapeutic opportunities to prevent infection. We report here on peptide amphiphile supramolecular nanofibers that display a sequence from ACE2 in order to promote interactions with the SARS-CoV-2 spike receptor binding domain. We demonstrate that displaying this sequence on the surface of supramolecular assemblies preserves its α-helical conformation and blocks the entry of a pseudovirus and its two variants into human host cells. We also found that the chemical stability of the bioactive structures was enhanced in the supramolecular environment relative to the unassembled peptide molecules. These findings reveal unique advantages of supramolecular peptide therapies to prevent viral infections and more broadly for other targets as well.

COVID-19 Therapeutic Potential of Natural Products.

Despite the fact that coronavirus disease 2019 (COVID-19) treatment and management are now considerably regulated, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is still one of the leading causes of death in 2022. The availability of COVID-19 vaccines, FDA-approved antivirals, and monoclonal antibodies in low-income countries still poses an issue to be addressed. Natural products, particularly traditional Chinese medicines (TCMs) and medicinal plant extracts (or their active component), have challenged the dominance of drug repurposing and synthetic compound libraries in COVID-19 therapeutics. Their abundant resources and excellent antiviral performance make natural products a relatively cheap and readily available alternative for COVID-19 therapeutics. Here, we deliberately review the anti-SARS-CoV-2 mechanisms of the natural products, their potency (pharmacological profiles), and application strategies for COVID-19 intervention. In light of their advantages, this review is intended to acknowledge the potential of natural products as COVID-19 therapeutic candidates.

New progresses on cell surface protein HSPA5/BiP/GRP78 in cancers and COVID-19.

Heat-shock-protein family A (Hsp70) member 5 (HSPA5), aliases GRP78 or BiP, is a protein encoded with 654 amino acids by the HSPA5 gene located on human chromosome 9q33.3. When the endoplasmic reticulum (ER) was stressed, HSPA5 translocated to the cell surface, the mitochondria, and the nucleus complexed with other proteins to execute its functions. On the cell surface, HSPA5/BiP/GRP78 can play diverse functional roles in cell viability, proliferation, apoptosis, attachments, and innate and adaptive immunity regulations, which lead to various diseases, including cancers and coronavirus disease 2019 (COVID-19). COVID-19 is caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, which caused the pandemic since the first outbreak in late December 2019. HSPA5, highly expressed in the malignant tumors, likely plays a critical role in SARS-CoV-2 invasion/attack in cancer patients via tumor tissues. In the current study, we review the newest research progresses on cell surface protein HSPA5 expressions, functions, and mechanisms for cancers and SARS-CoV-2 invasion. The therapeutic and prognostic significances and prospects in cancers and COVID-19 disease by targeting HSPA5 are also discussed. Targeting HSPA5 expression by natural products may imply the significance in clinical for both anti-COVID-19 and anti-cancers in the future.

Evaluation of Clinical Symptoms Improvement by Cognitive Behavioral Therapy Using a Smartphone Application in Patients with Temporomandibular Disorder.

Since the start of the 2019 coronavirus pandemic, interest in digital therapeutics (DTx) has increased. Temporomandibular disorder (TMD) fundamentally requires cognitive behavioral therapy (CBT), including physical self-regulation. An application that records TMD pain and parafunctional activities for CBT has recently been developed. However, evidence of the reduction of clinical symptoms in patients via repetitive software-driven CBT is lacking. The purpose of the present study was to evaluate the impact of applications that support CBT regarding the performance of CBT and the improvement of clinical symptoms in temporomandibular joint patients. From 20 October 2020 to 7 January 2021, we randomly assigned 41 participants diagnosed with TMD to control (conventional treatment) and experimental (conventional treatment + application use) groups. We randomly assigned 41 participants diagnosed with TMD to control (conventional treatment) and experimental (conventional treatment + application use) groups. Improvements regarding the number of tender points, mouth opening, visual analog scale score, pain level upon palpation, joint sound, and stress were compared between the two groups. Compared with the control group, the experimental group showed significant improvements in the number of tender points and degree of mouth opening. They also showed improvements in pain level, joint sound, and locking, although not statistically significantly, as compared with the control group. Thus, further studies with a greater sample size need to be conducted to confirm the findings. Nevertheless, our results showed that repetitive cognitive behavioral therapy using a smartphone application can be used as digital therapeutics for temporomandibular disorder patients.

Comparison of the risk of hospitalisation among BA.1 and BA.2 COVID-19 cases treated with sotrovimab in the community in England.

There are concerns that sotrovimab has reduced efficacy at reducing hospitalisation risk against the BA.2 sub-lineage of the Omicron SARS-CoV-2 variant. We performed a retrospective cohort (n = 8850) study of individuals treated with sotrovimab in the community, with the objective of assessing whether there were any differences in risk of hospitalisation of BA.2 cases compared with BA.1. We estimated that the hazard ratio of hospital admission with a length of stay of 2 days or more was 1.17 for BA.2 compared with BA.1 (95%CI 0.74-1.86). These results suggest that the risk of hospital admission was similar between the two sub-lineages.

An efficient computational protocol for template-based design of peptides that inhibit interactions involving SARS-CoV-2 proteins.

The RNA-dependent RNA polymerase (RdRp) complex of SARS-CoV-2 lies at the core of its replication and transcription processes. The interfaces between holo-RdRp subunits are highly conserved, facilitating the design of inhibitors with high affinity for the interaction interface hotspots. We, therefore, take this as a model protein complex for the application of a structural bioinformatics protocol to design peptides that inhibit RdRp complexation by preferential binding at the interface of its core subunit nonstructural protein, nsp12, with accessory factor nsp7. Here, the interaction hotspots of the nsp7-nsp12 subunit of RdRp, determined from a long molecular dynamics trajectory, are used as a template. A large library of peptide sequences constructed from multiple hotspot motifs of nsp12 is screened in-silico to determine sequences with high geometric complementarity and interaction specificity for the binding interface of nsp7 (target) in the complex. Two lead designed peptides are extensively characterized using orthogonal bioanalytical methods to determine their suitability for inhibition of RdRp complexation. Binding affinity of these peptides to accessory factor nsp7, determined using a surface plasmon resonance (SPR) assay, is slightly better than that of nsp12: dissociation constant of 133nM and 167nM, respectively, compared to 473nM for nsp12. A competitive ELISA is used to quantify inhibition of nsp7-nsp12 complexation, with one of the lead peptides giving an IC50 of 25µM . Cell penetrability and cytotoxicity are characterized using a cargo delivery assay and MTT cytotoxicity assay, respectively. Overall, this work presents a proof-of-concept of an approach for rational discovery of peptide inhibitors of SARS-CoV-2 protein-protein interactions.

Applications of advances in mRNA-based platforms as therapeutics and diagnostics in reproductive technologies.

The recent COVID-19 pandemic led to many drastic changes in not only society, law, economics, but also in science and medicine, marking for the first time when drug regulatory authorities cleared for use mRNA-based vaccines in the fight against this outbreak. However, while indeed representing a novel application of such technology in the context of vaccination medicine, introducing RNA into cells to produce resultant molecules (proteins, antibodies, etc.) is not a novel principle. It has been common practice to introduce/inject mRNA into oocytes and embryos to inhibit, induce, and identify several factors in a research context, while such aspects have also been proposed as potential therapeutic and diagnostic applications to combat infertility in humans. Herein, we describe key areas where mRNA-based platforms have thus far represented potential areas of clinical applications, describing the advantages and limitations of such applications. Finally, we also discuss how recent advances in mRNA-based platforms, driven by the recent pandemic, may stand to benefit the treatment of infertility in humans. We also present brief future directions as to how we could utilise recent and current advancements to enhance RNA therapeutics within reproductive biology, specifically with relation to oocyte and embryo delivery.

Hemoglobin-Based Oxygen Carriers: Brief History, Pharmacology and Design Strategies, Review of the Major Products in Clinical Trials, On-Going Studies, and Coagulation Concerns

Transfusion of erythrocytes (RBC) to treat acute or chronic anemia has significant drawbacks, given the risks of transfusion, volunteer donor requirements, limited supply with increasing demand, especially during a pandemic such as COVID-19, and erythrocytes are often unavailable in emergency situations or where blood is not an option. Significant research has been undertaken for almost 100 years to attempt to replicate the functions of RBCs with oxygen carriers/oxygen therapeutics based on hemoglobin. Oxygen carriers that have been evaluated are hemoglobin-based oxygen carriers (HBOCs). HBOCs utilize hemoglobin (Hb) to transport oxygen around the body. Blood transfusion may be critical therapy in hemorrhagic trauma, various pathologies both acute and chronic, and surgical interventions. It has some important goals: the first and most important is to recover oxygen delivery to organs, additionally, when restoration of circulating blood volume is achieved, maintenance of adequate blood pressure to ensure enough blood flow to deliver the oxygen to the microcirculation and resolving oxygen debt. This chapter will review the history of HBOCs, discuss how HBOCs have been designed and how developed HBOCs differ from each other based on their pharmacology and physiology, highlight all major products to undergo human trials including one extensively studied product approved for human use in two countries (Hemopure), introduce newer products still under development, and finally present translational and clinical trials studying whether or not certain HBOCs may cause coagulation issues. © The Editor(s) (if applicable) and The Author(s), under exclusive license to Springer Nature Switzerland AG 2022.

Diagnostic and Neutralizing Aptamers Technology against Sars-Cov-2

Severe acute respiratory syndrome coronavirus 2 (Sars-Cov-2) variants in a perpetual state of evolution are persistently challenging the development of medical therapeutics. Continuing beyond the mutation escape of variants requires a specific, stable, point-of-care, modifiable, and low-cost therapeutic reagent for both prophylactic treatment and clinical treatment. The nucleic acid-based approach, aptamer, has become one of the most competitive candidates for this high-demand anti-covid treatment. As current substantial research has consolidated its optimistic biosensor role in the field of detection and diagnostics for Sars-Cov-2, it is undoubtedly worth exploring aptamers as neutralizing agents. The applicability of aptamers with refined advantages should not only allow more possibilities in screening and diagnosis but also confer promising capabilities in neutralization, chimeric therapy, delivery, and vaccines for COVID-19. Therefore, the paper, through the method of literature review, reveals the current state of coronavirus and aptamer, summarizes the recent developments in theranostic aptamers, anti-Sars-Cov-2 neutralizing aptamers, and combined aptamers, and the prospect of aptamer research, including its challenges and focus. The paper concludes that aptamer-based biosensors, rapid antigen tests, and treatments are promising priorities against COVID-19 as diagnostic-aimed and neutralizing-aimed aptamers have been developed during the past two years. Although RBD-targeted and multivalent aptamers partly dampen the burden of nonspecificity and low effectivity, pushing into the "in vivo” testing stage and tackling frequent mutation escape should be the future research focus. © 2023 SPIE.
