The patient is a 58-year-old male who presented with chief complaints of right-sided numbness, tingling, and loss of temperature sensation in the upper and lower extremities. The patient’s symptoms began around the face and right corner of the mouth [maxillary/mandibular (V2/V3) distribution] before descending to the arm, trunk, and followed by the lower leg and foot. His home medication regimen included lisinopril, atorvastatin, long and short-acting insulin, and amlodipine. During the interview, the patient admitted to abstinence from his medications. Upon examination, the patient was found to have a loss of hot and cold touch on the right side and expressed 2+ reflexes (brisk response; normal) on both upper and lower extremities. In the initial work-up of the patient, he received a computed tomography (CT) scan which demonstrated an area of potential ischemic infarct of one of the left sided pontine perforator arteries. Immediately at that time he was given a loading dose of 325 mg aspirin and started on 81 mg daily. Because of the patient’s symptoms and risk factors, he was hospitalized for further additional work-up and eventually discharged on dual antiplatelet therapy. This case is intriguing as both neuroradiological reading and neurological examination helped with localization of the lesion and changing the treatment strategy of the patient. With a pontine perforator ischemic event, the harms of treatment with thrombolytics would have outweighed the benefits. This interprofessional work between neuroradiology, internal medicine, and neurology ensured that the patient received the best care for his specific ailments.

Oral cancer is the most common carcinoma of head and neck cancers. The majority of oral cancers are oral squamous cell carcinoma (OSCC). Among the various etiological factors, oral microbes—bacteria are also associated with pathogenesis of OSCC. But only few studies have been done associating the presence of oral bacteriome with OSCC. The main aim of this review is to focus on association of microbes with OSCC, the pathogenesis, variation in bacteriome profiling in different geographic conditions, their role in pathogenesis of OSCC, and different samples and methods that are used to study their association with habits and tumour node metastasis (TNM) staging. To conclude, the imbalance in the oral bacteriome could be considered an etiological factor for OSCC. Since the bacteriome profiling varies greatly with geographic location and even in an individual in different locations of the oral cavity, it advocates more research. The study on identifying bacteria associated with OSCC will also enable their use as diagnostic markers and preventive management of OSCC.

Infection and suppuration of chronic wounds reduce the effectiveness of their treatment with a course of antibiotics and antiseptics combined with frequently renewed dressings. Therefore, daily short-term procedures of cleaning wounds from purulent-necrotic masses by mechanical methods, including the use of cleansing solutions and necrophage fly larvae, are also part of the general practice of chronic wound treatment. But even they do not always provide rapid healing of chronic wounds. In this connection, it is suggested to supplement the treatment of chronic wounds with preparations dissolving dense pus and wound dressings made in the form of warm moist compresses creating a local greenhouse effect in the wounds. Solutions of 3% hydrogen peroxide and 2–10% sodium bicarbonate heated to a temperature of 37°–45°С, possessing alkaline activity at рН 8.4–8.5 and enriched with dissolved carbon dioxide or oxygen gas (due to overpressure of 0.2 atm were suggested as pyolytic drugs. The first results of the use of pyolytics and warm moist dressings-compresses in the treatment of chronic wounds demonstrate a wound-healing effect. It is suggested to consider sanitizing therapy with pyolytics and warm moist wound dressings-compresses as an alternative to the use of modern cleansing solutions and artificial introduction of larvae of the necrophage fly into the purulent masses of chronic wounds to dissolve dense pus and accelerate the healing process.

Aim: Cannabis use for sleep-related problems is on the rise; however, little is known about the cannabis products people are using for sleep or the perceived effects of cannabis in comparison to more conventional sleep aids. Therefore, the aim of this study was to examine the products cannabis users prefer to use for sleep as well as their experiences with cannabis relative to more conventional sleep aids. Methods: De-identified archival data from a Strainprint® survey of 1,216 individuals who use cannabis for sleep were analyzed. Results: Participants predominantly reported smoking joints or vaping flower as their methods of administration, and seeking tetrahydrocannabinol (THC), cannabidiol (CBD), and the terpene myrcene in the cannabis they use for sleep. Only a small minority reported using cannabis in conjunction with conventional sleep aids. Comparisons of the self-reported effects of cannabis to conventional sleep aids revealed that participants reported feeling more refreshed, focused, better able to function, fewer headaches, and less nausea the morning after using cannabis for sleep than after using more conventional sleep aids or no sleep aids. However, they indicated they were more sleepy, anxious, and irritable in the mornings following the use of cannabis relative to other sleep aids. Participants were more likely to report red eyes and thirst and less likely to report nausea, anxiety, paranoia, and racing heart as side effects of cannabis relative to other sleep aids. Conclusions: Knowledge gained from this survey will provide health professionals with a better understanding of why people are using cannabis for sleep and may help guide future more controlled research.

Aim: Parkinson’s disease (PD) is a complex, chronic neurodegenerative disorder with predominately sporadic etiology. Intricate genetic-environmental interactions lead to the hallmarks of the disease: degeneration of dopaminergic neurons and the deposition of α-synuclein aggregates. The aim of this study was to establish a novel primary patient cell model as an in vitro screen to study α-synuclein processing for drug screening. Methods: Primary patient olfactory neuroepithelial-derived cells (ONS) were exposed to α-synuclein and examined for cytotoxicity, processing, and solubility over 48 h. Epigallocatechin gallate (EGCG), which is known to destabilise α-synuclein fibrils, was used to investigate the solubilisation of α-synuclein in the model system. Results: Exposure to 0.1 μmol/L α-synuclein preformed fibrils was not toxic to ONS over 48 h. ONS processing of α-synuclein was observed to be different in PD cells by their increased accumulation in the cytoplasm. Processing deficits in the PD ONS were confirmed by immunoblotting with an increase in sodium dodecyl sulfate (SDS)-insoluble α-synuclein after 48 h. Conclusions: The data has illustrated the utility of primary patient ONS as a model system to understand the processing of α-synuclein. Considerable differences in α-synuclein processing were identified in PD ONS. Furthermore, the data suggests that primary patient ONS are a viable in vitro drug screening platform for α-synuclein pathology in PD.

Bell’s palsy is a rapid unilateral peripheral paralysis of cranial nerve VII whose etiology is varied, most commonly associated with an acute infectious or inflammatory demyelinating process. Nerve injury can result in edema because of increased permeability of vascular structures, which can sometimes be seen as a locus of enhancement of magnetic resonance imaging (MRI). Bell’s palsy is typically considered a clinical diagnosis and the specificity and sensitivity of imaging have been poorly studied. Herein is describe a case of a 73-year-old male who presented to the emergency department with left-sided facial droop and no other focal neurological abnormalities. With a history of a Janus kinase 2 (JAK2) mutation and the new initial facial drooping, acute cerebrovascular insult was high on the differential. Initial labs and computerized tomography (CT) head were inconclusive, but MRI showed pronounced enhancement of the left distal internal carotid artery (ICA) with contiguous enhancement of the labyrinthine, geniculate, and tympanic segments of the left facial nerve. Diagnosing Bell’s palsy can be a challenge as there are numerous postulated etiologies stemming from trauma, infection, and neoplasm; with infection (particularly viral) postulated to be the most likely source. Though MRI is currently not validated as a tool in expediting Bell’s palsy diagnosis, findings such as the enhancement seen here provide some insight into the benefit of MRI as a diagnostic modality in some cases. This case is unique both for the diagnostic dilemma between stroke and Bell’s palsy and the potential for MRI imaging to help guide clinical decision-making into treatment.

Self-replicating RNA viruses such as alphaviruses, flaviviruses, paramyxoviruses, and rhabdoviruses have been engineered as expression vectors for vaccine development. The prominent feature of self-replicating RNA viruses is their RNA-dependent RNA polymerase activity, which generates massive self-amplification of RNA in the cytoplasm of infected host cells leading to extreme levels of transgene expression. Infectious diseases have been targeted by overexpression of surface proteins of pathogens as antigens for vaccine development. Moreover, overexpression of tumor-associated antigens and immunostimulatory genes has been the basis for cancer vaccines. Proof-of-concept of robust antigen-specific immune responses and protection against challenges with lethal doses of infectious agents have been demonstrated. Likewise, vaccine development against various cancers has elicited strong immune responses and resulted in tumor regression and eradication, cure, and prolonged survival in animal tumor models. Good safety and immune responses have been achieved in clinical trials. The ERVEBO® vaccine, based on the vesicular stomatitis virus, has been approved for immunization against the Ebola virus disease.

Diabetes mellitus has become increasingly more common and diagnosed within the global population. Coupled with the continued prevalence of substance use, there are some distinct considerations for users suffering (knowingly or unknowingly) from type 1 or type 2 diabetes. The various different types of drugs of abuse including central nervous system stimulants, depressants, and hallucinogens present varying direct and indirect complications for diabetes based on their physiological and psychological effects ranging from non-compliance with medication to an increased risk of hypoglycaemia, hyperglycaemia, and/or ketoacidosis. This perspective highlights these issues supported by the drug history and toxicological findings in patients undergoing drug rehabilitation in the United Arab Emirates (UAE) demonstrating the use of alcohol, amphetamines, benzodiazepines, cannabis, opiates/opioids (especially tramadol), pregabalin, and synthetic cannabinoids. Physicians and drug clinic professionals should be aware of the contraindications of substance use and diabetes with a view to educating patients and healthcare professionals within such clinical settings.

Complex enzyme interactions play a role in the spread of cancer, a process fueled by unregulated cell proliferation. DNA topoisomerases, which are important for fixing DNA topological problems, have drawn a lot of interest as potential targets for anti-cancer medications. Cancer treatment, which includes radiation, surgery, and chemotherapy, tries to control cell survival, demise, and mobility, which are mediated by ion transportation across cell membranes via channels and carriers. The malignant transition is characterised by altered channels and carriers. Chemoresistance, which commonly develops after chemotherapy, denotes decreased therapeutic effectiveness against cancer progression. Chemosensitizers are used in combination with anti-cancer medications to overcome this resistance, particularly against adenosine triphosphate (ATP)-binding cassette (ABC) transporters including P-glycoprotein, multidrug resistance-associated protein 1 (MRP1), breast cancer resistance protein (BCRP). Effective targets for treatment are transcription factors, which play a key role in the development of cancer. With the use of interactions with receptors, enzymes, ion channels, transporters, and TFs, nanotechnology improves the safety of tumour localization, treatment, and diagnostics. As a result of mutations or altered signalling, rat sarcoma (RAS) proteins regulate signalling, which is essential for both healthy growth and the development of cancer. Rational treatments that target RAS pathways have the potential to inhibit the growth and spread of tumours. New treatments are still being developed, and they are showing promise in clinical settings. The roles of receptors on tumour cells, their significance for cancer therapy, and recent advancements in preclinical and clinical research are all included in this overview.

New treatments are still being developed, and they are showing promise in clinical settings. The roles of receptors on tumour cells, their significance for cancer therapy, and recent advancements in preclinical and clinical research are all included in this overview.","PeriodicalId":72999,"journal":{"name":"Exploration of medicine","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135437436","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Aim: The purpose of this study was to examine the association among body mass, blood pressure (BP), and cognitive functioning for octogenarians and centenarians. Methods: A total of 300 participants (221 centenarians and 79 octogenarians) from the Georgia Centenarian Study were included in this study. Demographic variables included age, gender, and ethnicity. Body mass was measured with the body mass index (BMI), and systolic and diastolic BP, as well as mean arterial pressure (MAP) and the Mini-Mental Status Examination (MMSE) were assessed. Results: Results showed age differences indicating that centenarians had lower BMI and MMSE scores when compared to octogenarians. Women had lower cognitive functioning scores compared to men. Black Americans had higher BMI and BP as well as lower MMSE scores. Participants with low BMI values (< 18.5 kg/m2) and normal BP had a significantly lower MMSE score when compared to those with elevated BMI values (≥ 25 kg/m2 to < 30 kg/m2) and high BP. Multiple regression analyses determined that age, gender, ethnicity, and BMI were significantly associated with cognitive function in very late life. Conclusions: The results suggest that extreme values of body mass (low and high) in combination with normal BP (< 130 mmHg) are potential risk factors for compromised cognition.
