Cariogenic Biofilm

The initiation and development of cariogenic (that is, caries-related) biofilms are the result of the disruption of homeostasis in the oral microenvironment. There is a daily accumulation of dental biofilm on the surface of teeth and its matrix of extracellular polymers supports the host in its defense against invading microbes, thus helping to achieve oral microbial homeostasis. However, the homeostasis can be broken down under certain circumstances such as during long-term exposure to a low pH environment which results in the dominance of acidogenic and acid-tolerating species in the dental biofilm and, thus, triggers the shift of harmless biofilm to an acidic one. This work aims to explore microbial diversity and the quorum sensing of dental biofilm and their important contributions to oral health and disease. The complex and multispecies ecosystems of the cariogenic biofilm pose significant challenges for the modulation of the oral microenvironment. Promising treatment strategies are those that target cariogenic niches with high specificity without disrupting the balance of the surrounding oral microbiota. Here, we summarized the recent advances in modulating cariogenic biofilm and/or controlling its pathogenic traits.

In the context of the COVID-19 pandemic, healthcare is faced with several new problems, one of which is a post-covid syndrome. Symptoms in many COVID-19 survivors can persist for a long time, significantly affecting the quality of life and work performance. All of the above makes post-covid syndrome a socially significant disease, requires dynamic follow-up of such patients, and rehabilitation programs development. We are currently at the stage of accumulating knowledge about the SARS-CoV-2 pathophysiology and morphogenesis and its long-term consequences. This article discusses neuropsychiatric aspects of the post-covid syndrome: pathogenetic hypotheses, clinical features, and potentially promising treatment strategies.

Prevention Of Bone Loss

The gut microbiome appears to be a significant contributor to musculoskeletal health and disease. Recently, it has been found that oral microbiota are involved in arthritis pathogenesis. Microbiome composition and its functional implications have been associated with the prevention of bone loss and/or reducing fracture risk. The link between gut–oral microbiota and joint inflammation in animal models of arthritis has been established, and it is now receiving increasing attention in human studies. Recent papers have demonstrated substantial alterations in the gut and oral microbiota in patients with rheumatoid arthritis (RA) and osteoarthritis (OA). These alterations resemble those established in systemic inflammatory conditions (inflammatory bowel disease, spondyloarthritides, and psoriasis), which include decreased microbial diversity and a disturbance of immunoregulatory properties. An association between abundance of oral Porphyromonas gingivalis and intestinal Prevotella copri in RA patients compared to healthy controls has been clearly demonstrated. These new findings open important future horizons both for understanding disease pathophysiology and for developing novel biomarkers and treatment strategies. The changes and decreased diversity of oral and gut microbiota seem to play an important role in the etiopathogenesis of RA and OA. However, specific microbial clusters and biomarkers belonging to oral and gut microbiota need to be further investigated to highlight the mechanisms related to alterations in bones and joints inflammatory pathway.

Abstract Background：Pressure ulcer is a common complication of long-term bedridden patients, but current treatment strategies have limited efficacy for pressure ulcer. Case presentation：We present a 17-year-old man with unstageable pressure ulcer treated with three-dimensional conformal radiotherapy. We irradiate the posterior lumbosacral pressure ulcer with 3D-CRT using a 6 MV photon beam. The patient was placed in a prone position and a total dose of 50cGy was administered. Then, the healing was evaluated using PUSH scale score on days 8，12 and 3 months after radiotherapy. After radiotherapy, beefy red tissue with a shiny, moist, granular appearance tissue are present in the wound bed, exudate amount was decreased, the depth of the pressure ulcer became significantly shallower and the wound surface area was reduced. PUSH scale score descreased from15 to 7.Conclusion: Radiotherapy could be a promising treatment strategy of unstageable pressure ulcer.

Abstract The steady increase in linguistic and cultural diversity in the country, including the number of bilingual speakers, has been predicted to continue. Minorities are expected to be the majority by 2042. Strokes, the third leading cause of death and the leading cause of long-term disability in the U.S., are quite prevalent in racial and ethnic minorities, so population estimates underscore the imperative need to develop valid clinical procedures to serve the predicted increase in linguistically and culturally diverse bilingual adults with aphasia in post-stroke rehabilitation. Bilingualism is a complex phenomenon that interconnects culture, cognition, and language; thus, as aphasia is a social phenomenon, treatment of bilingual aphasic persons would benefit from conceptual frameworks that exploit the culture-cognition-language interaction in ways that maximize both linguistic and communicative improvement leading to social re-adaptation. This paper discusses a multidisciplinary evidence-based approach to develop ecologically-valid treatment strategies for bilingual aphasic individuals. Content aims to spark practitioners' interest to explore conceptually broad intervention strategies beyond strictly linguistic domains that would facilitate linguistic gains, communicative interactions, and social functioning. This paper largely emphasizes Spanish-English individuals in the United States. Practitioners, however, are advised to adapt the proposed principles to the unique backgrounds of other bilingual aphasic clients.

Peptide Fibrils

Alzheimer’s disease is the most common form of dementia. It is characterized by betaamyloid peptide fibrils which are extracellular deposition of a specific protein, accompanied by extensive neuroinflammation. Various studies show the presence of a number of inflammation markers in the AD brain: elevated inflammatory cytokines and chemokines, and an accumulation of activated microglia in the damaged regions. NF-κB is a family of redox sensitive transcriptional factors, and it is known that NF-κB has binding sites in the promoter region of the genes involved in amyloidogenesis and inflammation. Long-term use of non-steroidal anti-inflammatory drugs prevents progression of AD and delays its onset, suggesting that there is a close correlation between NF-κB and AD pathogenesis. This study aims to (1) assess the association between NF-κB activity and AD through discussion of a variety of experimental and clinical studies on AD and (2) review treatment strategies designed to treat or prevent AD with NF-κB inhibitors.

Immunological memory is classically attributed to adaptive immune responses, but recent studies have shown that challenged innate immune cells can display long-term functional changes that increase nonspecific responsiveness to subsequent infections. This phenomenon, coined <i>trained immunity</i> or <i>innate immune memory</i>, is based on the epigenetic reprogramming and the rewiring of intracellular metabolic pathways. Here, we review the different metabolic pathways that are modulated in trained immunity. Glycolysis, oxidative phosphorylation, the tricarboxylic acid cycle, amino acid, and lipid metabolism are interplaying pathways that are crucial for the establishment of innate immune memory. Unraveling this metabolic wiring allows for a better understanding of innate immune contribution to health and disease. These insights may open avenues for the development of future therapies that aim to harness or dampen the power of the innate immune response.

AbstractModern treatment strategies have improved prognosis and survival of patients with malignant diseases. The key components of tumor treatment are conventional chemotherapy, radiotherapy, targeted therapies, and immunotherapy. Cardiovascular side-effects may occur in the early phase of tumor therapy or even decades later. Therefore, knowledge and awareness of acute and long-lasting cardiac side effects of anti-cancer therapies are essential. Cardiotoxicity impairs quality of life and overall survival. The new cardiologic subspecialty ‘cardio-oncology’ deals with the different cardiovascular problems arising from tumor treatment and the relationship between cancer and heart diseases. Early detection and treatment of cardiotoxicity is of crucial importance. A detailed cardiac assessment of patients prior to administration of cardiotoxic agents, during and after treatment should be performed in all patients. The current review focusses on acute and long-term cardiotoxic side effects of classical cytotoxic and selected modern drug treatments such as immune checkpoint inhibitors and discusses strategies for the diagnosis of treatment-related adverse cardiovascular effects in cancer patients.

Pain Management Strategy

Abstract Opioids are often the first-line chronic pain management strategy for long-term care (LTC) residents who are also at increased risk for opioid-related adverse events. Therefore, there is a need to train LTC providers and staff about appropriate opioid use and alternative treatment strategies. Our interdisciplinary team worked with LTC partners to identify staff educational needs around opioid stewardship. Based on this need’s assessment, we developed eight modules about opioid use and risks for older adults, including those with dementia, recommendations for de-prescribing including other pharmacological and non-pharmacological alternatives, SBIRT, and motivational interviewing to determine “what matters”. Each 20-minute module contains didactic and video content that is appropriate for group staff training or individuals and provides rural LTC facilities access to needed training in their home communities. Within the first month of launching online, the program received over 1100 hits and LTC partners are incorporating modules into clinical staff training schedules.
