Since the early 1970s, the U.S. Food and Drug Administration (FDA) has received over 800 investigational new drug applications (INDs) for, and pre-INDs pertaining to, research of cannabis or cannabis-derived products. The current data show that applications for research of these products submitted by both academic researchers and commercial developers focus on four major clinical areas: addiction and pain medicine (53%), neurology (19%), immunology and inflammation (14%), and psychiatry (9%). The product types studied have expanded greatly in recent years and include a wide variety of topical, inhalable, injectable, and oral products. In this article, the authors present a breakdown of cannabis and cannabis-derived applications received by the FDA over the past 50 years. The authors also provide a summary of their experience and challenges in reviewing applications for research of cannabis and cannabis-derived products, as well as recommendations for those interested in studying cannabis and cannabis-derived products in human clinical trials. This perspective article includes a discussion on important IND criteria, the pre-IND consultation program, drug master files (DMFs), and various guidance documents and resources. Lastly, the authors provide their perspective for the future of cannabis drug development.

Aim: Coronavirus disease 2019 (COVID-19) is a respiratory infection caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The SARS-CoV-2 has undergone several mutations, and ultimately, Indonesia was designated the Asian epicenter of the pandemic in 2021 due to the emergence of Delta variant SARS-CoV-2. Therefore, this study aimed to determine the characteristics of the Delta variant SARS-CoV-2 gene mutations. Methods: This is a cross-sectional descriptive study to determine the mutation characteristics of the Delta variant SARS-CoV-2 with data collected from patients’ medical records and whole genome sequencing (WGS). Results: The forty-nine patients who contracted the Delta variant SARS-CoV-2 were mainly aged 31−45 years and female. Four sublineages were identified, namely AY.23 (69.39%), AY.24 (22.45%), B.1.617.2 (6.12%), and AY.62 (2.04%), with fever and malaise being the most common clinical manifestations (79.60%). Furthermore, the spike (S) protein was most frequently mutated (12 mutations), with mutations in the Delta variant SARS-CoV-2 membrane (M) protein, nucleocapsid (N) protein, open reading frame (ORF), and nonstructural protein (NSP) also identified. Conclusions: The most common Delta variant SARS-CoV-2 sublineage in the current study cohort was AY.23, with the S protein being most frequently mutated. Continuous genomic surveillance is required to contain future outbreaks or infection waves, especially during the COVID-19 pandemic.

The prevalence of skin cancer has increased hastily in the recent decade for both kinds of melanoma and non-melanoma skin cancer. Skin cancers mostly encompass keratinocyte cancers: cutaneous squamous cell carcinoma, basal cell carcinoma, and melanoma. This review discusses the recent advancements in the treatment of skin cancer. In addition to chemotherapy, immunotherapy, targeted therapy, and photodynamic therapy (PDT), there are several other therapies for skin cancer. Additionally, PDT use in combination with chemotherapy, radiation, immunotherapy, and surgery is being actively investigated. This review will specifically address the pathophysiology of skin cancer, diagnostic approaches, and current therapies used in the topical treatment of skin cancers and introduce emerging treatment using nanotechnology that may be beneficial for these indications.

The paper aims to review the possibilities of a complex transdisciplinary approach to forming health and longevity. Determinants of productive longevity (DPL) and health culture are reviewed; definitions of health, stress, and eustress, and their roles in active and productive longevity are given. DPL making a decisive contribution to the phenomenon of active longevity are stated and analyzed from the point of view of evidence-based medicine. They are as follows: 1) environmental factors including geographical location, “Blue zones”, and mountain areas, as well as level of the environmental pollution; 2) dietary regimen to support active longevity, including vegetarianism, calorie restriction, fasting, the role of vitamins, biological antioxidants, geroprotectors, and micronutrients; 3) importance of activity and eustress phenomenon, by other words, lifestyle: physical activity, sexual relationship, Qigong and Yoga practices, cognitive activity, sense of humor, and acceptance of age in activities of daily living and survival; 4) genetic and epigenetic particularities as a condition for long-living; 5) level of health care and early diagnostics to prevent age-associated diseases; 6) the role of the state of mind and meditation as well, how it is used for forming health due to Qigong and Yoga natural systems, in religion, and medical practice; 7) motivation for active longevity that significantly increases chances to productive longevity.

Radiation is a primary therapy in the treatment of thoracic malignancies with clear survival benefits. Consequently, patients with cancer are living longer but may be subject to a wide array of cardiotoxic effects from collateral radiation damage. Ensuing fibrosis can affect any portion of the cardiac parenchyma, increasing the risk for accelerated coronary artery disease, pericardial sequelae such as constrictive pericarditis, valvulopathy, restrictive cardiomyopathy, and a myriad of conduction system abnormalities. Unfortunately, the effects of cardiotoxicity can be subclinical or delayed and there remains an unmet need to standardize management strategies for these patients. Based on current data, it is prudent to consider percutaneous approaches first for coronary and valvular disease and traditional, supportive measures for the remaining sequelae. Every attempt should be made to undergo a complete operative haul due to the increased risks of re-operation if surgery is to be performed. Surrounding the patient with a multidisciplinary heart team is critical.

This case report demonstrates the successful induction of apexogenesis in an extensively carious lower right first molar with immature roots through the use of stepwise excavation and calcium-enriched mixture (CEM) cement as an indirect pulp capping material. The patient, an 8-year-old boy, presented with pain and carious pulp exposure. The initial treatment involved removing soft dentin and applying CEM cement as an indirect pulp cap. The patient experienced pain relief after 24 h, and subsequent follow-up appointments showed complete healing and maturation of the tooth. The case highlights the potential of indirect pulp treatment with CEM cement and emphasizes the importance of regenerative biomaterials in promoting healing and dentin bridge formation. Further clinical work and research are recommended to explore the efficacy of this treatment approach.

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.
{"title":"A large-scale survey of cannabis use for sleep: preferred products and perceived effects in comparison to over-the-counter and prescription sleep aids","authors":"Amanda Stueber, Carrie Cuttler","doi":"10.37349/emed.2023.00171","DOIUrl":"https://doi.org/10.37349/emed.2023.00171","url":null,"abstract":"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.","PeriodicalId":72999,"journal":{"name":"Exploration of medicine","volume":"7 6","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135113966","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}
