  Objective: This review aimed to provide an update on the characterization and impact of musculoskeletal pain in COVID-19 survivors. Methods: It is considered articles on subjects who had been recovered from COVID-19 infection after hospitalization (COVID-19 survivors) with secondary musculoskeletal pain. Results: Six articles (one editorial, one consensus statement, one letter to the editor, one case-control study, one cohort study and one review) showed the polyhedral effects of the SARS-CoV-2 on musculoskeletal pain. This short review was not able to clearly identify what the pathogenesis of musculoskeletal pain was in COVID-19 survivors. Conclusion: Preliminary data showed that widespread pain similar to the pattern compatible with pain of musculoskeletal origin could characterize symptoms after SARS-CoV-2 infection.  Resumen. Objetivo: Esta revisión tuvo como objetivo proporcionar una actualización sobre la caracterización y el impacto del dolor musculoesquelético en los supervivientes de COVID-19. Métodos: Se consideraron artículos sobre sujetos que se recuperaron de la infección por COVID-19 tras la hospitalización (supervivientes de COVID-19) con dolor musculoesquelético secundario. Resultados: Seis artículos (un editorial, una declaración de consenso, una carta al editor, un estudio de casos y controles, un estudio de cohortes y una revisión) mostraron los efectos poliédricos del SARS-CoV-2 sobre el dolor musculoesquelético.  Esta breve revisión no pudo identificar claramente cuál era la patogénesis del dolor musculoesquelético en los supervivientes del COVID-19. Conclusión: Los datos preliminares mostraron que el dolor generalizado similar al patrón compatible con el dolor de origen musculoesquelético podría caracterizar los síntomas después de la infección por SARS-CoV-2.

In the present short review for the Sherman Award, Dr Yamaguchi introduces studies at the National Cerebral and Cardiovascular Center, Osaka, which included development of intravenous thrombolysis using low-dose alteplase that was officially approved in Japan, long-term dual antiplatelet therapy using cilostazol together with aspirin or clopidogrel, and others. He also discusses efforts to ensure the passage of the “Stroke and Cardiovascular Disease Control Act,” the aims of which are better primary prevention, better acute treatment, rehabilitation, and secondary prevention of stroke for people living in Japan.

Bacteria possess an EF-Tu-based cytoskeleton.This article presents a short review. A number of questions which are not discussed in the former publications can be asked, such as: all bacteria possess a ribosomal protein synthesis system and, hence, also EF-Tu. EF-Tu is produced in an amount that is higher than the need for a function as translation elogation factor in ribsomal protein synthesis. This article tries to answer the question regarding the surplus of EF-Tu: formation of a "cell-wide web" by self-assembly as a feafure that stabilizes cell integrity. An additional question can be asked: what is the origin of this bacterial cytoskeleton? This article contains a speculation on this topic. A third question regards the'ntteructjon of ribosomes in the process of protemsynthesis: does the EF-Tu protein move to the ribosome, or does the ribosome move to the EF-Tu intergated in a fibril of the bacterial cytoskeleton? The former publication depicts electron micrographs which show colocalizatton of botth entities. EF-Tu is an example for aprotein with two independent functions: participation in the ribosomal protein synthesis as a kanslation elongation factor, and component of a bacterial cytoskeleton. This situation can open up a discussion ofthe sequence of events and states of early cells during evolution.

Contraction of striated muscle is triggered by a massive release of calcium from the sarcoplasmic reticulum (SR) into the cytoplasm. This intracellular calcium release is initiated by membrane depolarization, which is sensed by voltage-gated calcium channels CaV1.1 (in skeletal muscle) and CaV1.2 (in cardiac muscle) in the plasma membrane (PM), which in turn activate the calcium-releasing channel ryanodine receptor (RyR) embedded in the SR membrane. This cross-communication between channels in the PM and in the SR happens at specialized regions, the SR-PM junctions, where these two compartments come in close proximity. Junctophilin1 and Junctophilin2 are responsible for the formation and stabilization of SR-PM junctions in striated muscle and actively participate in the recruitment of the two essential players in intracellular calcium release, CaV and RyR. This short review focuses on the roles of junctophilins1 and 2 in the formation and organization of SR-PM junctions in skeletal and cardiac muscle and on the functional consequences of the absence or malfunction of these proteins in striated muscle in light of recently published data and recent advancements in protein structure prediction.

Introduction. Kaposi sarcoma (KS) is a low-grade mesenchymal tumor involving the blood and the lymphatic vessels that primarily effaces the skin and is mediated by human herpesvirus-8 (HHV-8) in more than 90% of patients. There are 4 distinct types of KS. Compared with the classic and AIDS-related variants, chronic lymphocytic leukemia (CLL) associated with KS is a relatively rare clinical condition; thus, only a few cases have been reported. Case Report. This report presents a case study of an 87-year-old patient with B-cell CLL and cutaneous KS managed with cryotherapy, along with a short review of the literature. Conclusions. Considering that the method is relatively simple and with few adverse effects, cryotherapy may represent a simple and safe treatment method for cutaneous KS. However, more studies should be conducted to further evaluate the effectiveness of cryotherapy as a promising treatment for cutaneous KS.

Antiresorptive agents such as bisphosphonates (BP) and denosumab are commonly prescribed for the management of primary bone malignancy, bone metastasis, osteoporosis, Paget disease, or other bone disorders. Medication-related osteonecrosis of the Jaws (MRONJ) is a rare but significant complication of antiresorptive medications. Duration, dose, and antiresorptive potency as well as concomitant diseases, additional medications, and local factors affect MRONJ incidence and severity. MRONJ pathophysiology is still poorly understood. Nevertheless, decreased bone resorption due to osteoclastic inhibition along with trauma, infection/inflammation, or blood supply inhibition are considered synergistic factors for disease development. In addition, previous data research examined the effects of antiresorptive medication on immune system components and introduced potential alterations on immune response as novel elements in MRONJ pathogenesis. Considering that macrophages are the first cells in the nonspecific immune response, it is not surprising that these multifaceted players attracted increased attention in MRONJ research recently. This current review attempted to elucidate the effects of antiresorptive medications on several aspects of macrophage activity in relation to the complex inflammatory microenvironment of MRONJ. Collectively, unravelling the mode of action and extent of macrophages’ potential contribution in MRONJ occurrence will provide novel insight in disease pathogenesis and potentially identify intrinsic therapeutic targets.

Though heterogeneity of cancers is recognized and has been much discussed in recent years, the concept often remains overlooked in different routine examinations. Indeed, in clinical or biological articles, reviews, and textbooks, cancers and cancer cells are generally presented as evolving distinct entities rather than as an independent heterogeneous cooperative cell population with its self-oriented biology. There are, therefore, conceptual gaps which can mislead the interpretations/diagnostic and therapeutic approaches. In this short review, we wish to summarize and discuss various aspects of this dynamic evolving heterogeneity and its biological, pathological, clinical, diagnostic, and therapeutic implications, using thyroid carcinoma as an illustrative example.

PurposeThis paper offers a review of national and local planning policies towards warehouse development within the UK.Design/methodology/approachThe first sections of the paper provide a description of the simple method of enquiry and sources of information used in the paper, outlines of the main factors driving the demand for warehousing space in the UK, and of the nature, scale and operation of modern warehouses, and a short review into the limited literature published to date, on town planning and on how it has influenced warehouse development. This is followed by an examination of some of the planning issues associated with warehouse development, two mini-case studies of how these issues are perceived and played out, a discussion of some of the issues raised in this examination and the mini-case studies.FindingsTown planning policies were traditionally seen as a restraint on the development of warehousing but while current national and local planning policies make little explicit reference to warehousing, they have often been cited in support of new warehouse development because such policies emphasise the importance of supporting economic growth and fostering the conditions in which businesses can invest and expand.Research limitations/implicationsThe paper has a number of limitations, not least that its source material is drawn from the Internet, and in that no primary data were collected from warehouse developers, warehouse operators, local planning officers or local authority councillors, and that the geographical coverage was limited.Originality/valueThe paper offers an accessible review of the current town planning issues associated with warehouse development in the UK.
