Exploring the Therapeutic Potential of Flavonoids in the Management of Cancer.

Flavonoids are a class of polyphenolic compounds that can be classified into six distinct categories, namely isoflavonoids, flavanones, flavanols, flavonols, flavones, and anthocyanidins. These compounds are naturally occurring and can be found in a diverse range of plant species. Flavonoids, a class of bioactive compounds, are mostly obtained through the consumption of vegetables, fruits and plant-derived beverages such as wine, cocoa-based products and green tea. Flavonoids have been demonstrated to exhibit a diverse range of anticancer properties. These include the modulation of activities of enzymes involved in scavenging reactive oxygen species, involvement in cell cycle arrest, induction of apoptosis and autophagy, as well as suppression of cancer cell proliferation and invasiveness. Flavonoids exhibit a dual role in maintaining reactive oxygen species balance. They function as antioxidants in regular physiological conditions, while also demonstrating significant pro-oxidant properties in cancer cells. This prooxidant activity induces apoptotic pathways and downregulates pro-inflammatory signalling pathways. The paper explores the biochemical characteristics, bioavailability, anticancer efficacy, and modes of action of flavonoids.

Plant Adaptation and Tolerance to Heat Stress: Advance Approaches and Future Aspects.

Heat stress impacts plant growth at all phases of development, although the particular threshold for heat tolerance varies significantly across different developmental stages. During seed germination, elevated temperatures can either impede or completely halt the process, contingent upon the plant type and the severity of the stress. During advanced stages, high temperatures can have a negative impact on photosynthesis, respiration, water balance, and membrane integrity. Additionally, they can also influence the levels of hormones and primary and secondary metabolites. In addition, during the growth and development of plants, there is an increased expression of various heat shock proteins, as well as other proteins related to stress, and the generation of reactive oxygen species (ROS). These are significant plant responses to heat stress. Plants employ several strategies to deal with heat stress, such as maintaining the stability of their cell membranes, removing harmful reactive oxygen species (ROS), producing antioxidants, accumulating and adjusting compatible solutes, activating mitogen-activated protein kinase (MAPK) and calcium-dependent protein kinase (CDPK) cascades, and, crucially, signaling through chaperones and activating transcription. These molecular-level systems boost the ability of plants to flourish in heat stress. Potential genetic methods to enhance plant heat stress resistance encompass old and modern molecular breeding techniques and transgenic approaches, all of which rely on a comprehensive comprehension of these systems. Although several plants exhibit enhanced heat tolerance through traditional breeding methods, the effectiveness of genetic transformation techniques has been somewhat restricted. The latter results from the current constraints in our understanding and access to genes that have known impacts on plant heat stress tolerance. However, these challenges may be overcome in the future. Besides genetic methods, crops' heat tolerance can be improved through the pre-treatment of plants with various environmental challenges or the external application of osmoprotectants such as glycine betaine and proline. Thermotolerance is achieved through an active process in which plants allocate significant energy to maintain their structure and function to avoid damage induced by heat stress. The practice of nanoparticles has been shown to upgrade both the standard and the quantity of produce when crops are under heat stress. This review provides information on the effects of heat stress on plants and explores the importance of nanoparticles, transgenics, and genomic techniques in reducing the negative consequences of heat stress. Furthermore, it explores how plants might adapt to heat stress by modifying their biochemical, physiological, and molecular reactions.

Understanding Primary Care Physician Perspectives on the Diagnosis and Management of Non-Alcoholic Fatty Liver Disease: A Qualitative Study.

Primary care physicians (PCPs) are well suited to manage patients with non-alcoholic fatty liver disease (NAFLD), but the limited, existing research suggests inadequate knowledge about the natural history, diagnostic methods, and management of NAFLD. The purpose of this qualitative study is to further understand the knowledge and practices for the diagnosis and management of NAFLD among PCPs. We conducted in-depth interviews with PCPs in the Greater Houston area, addressing current clinical practices used for diagnosing and managing NAFLD, as well as the perceptions of the PCPs regarding the burden of NAFLD on patients. We recorded interviews, transcribed them, coded transcripts, and identified patterns and themes. The interviewed PCPs (n = 16) were from internal or family medicine, with a range of experience (1.5-30 years). We found variations in NAFLD diagnosis and management across practices and by insurance status. Patients with abnormal liver imaging who had insurance or were within a safety-net healthcare system were referred by PCPs to specialists. Uninsured patients with persistently elevated liver enzymes received lifestyle recommendations from PCPs without confirmatory imaging or specialist referral. The role of PCPs in NAFLD management varied, with some helping patients set dietary and physical activity goals while others provided only general recommendations and/or referred patients to a dietitian. The diagnosis and management of NAFLD vary widely among PCPs and may be impacted by patients' insurance status and clinic-specific practices. The increasing burden of NAFLD in the U.S. medical system highlights the need for more PCPs involvement in managing NAFLD.

Meralgia Paresthetica as a Result of Surgery With an Emphasis on Harvesting Iliac Bone Grafts: A Review.

Meralgia paresthetica is a neurological disorder characterized by a symptom complex of numbness, burning, tingling, aching, or stabbing in the anterolateral portion of the upper thigh. Typically, this disorder is seen in patients with diabetes mellitus, obesity, and pregnancy. Also, it may result from a wide array of surgical interventions involving the region of the anterior superior iliac spine. Underlying pathophysiology concentrates on entrapment neuropathy of the lateral femoral cutaneous nerve (LFCN). Due to its location and wide anatomic variation, the LFCN is susceptible to compression, scarring, and injury during surgery. It is important to understand the regional anatomy. In addition, the plastic surgeon must have a working knowledge of the most common variations that can precipitate entrapment and increase susceptibility to injury during surgery. Surgeons lacking a substantial background on the numerous risk factors, origins, and anatomic variations of the LFCN may place patients at an even higher risk of damage to the nerve. An extensive knowledge of the anatomy and careful technique may be utilized by surgeons to prevent iatrogenic neuropathy of the LFCN.

Potential Impact of Bioactive Compounds as NLRP3 Inflammasome Inhibitors: An Update.

The inflammasome NLRP3 comprises a caspase recruitment domain, a pyrin domain containing receptor 3, an apoptosis-linked protein like a speck containing a procaspase-1, and an attached nucleotide domain leucine abundant repeat. There are a wide variety of stimuli that can activate the inflammasome NLRP3. When activated, the protein NLRP3 appoints the adapter protein ASC. Adapter ASC protein then recruits the procaspase-1 protein, which causes the procaspase- 1 protein to be cleaved and activated, which induces cytokines. At the same time, abnormal activation of inflammasome NLRP3 is associated with many diseases, such as diabetes, atherosclerosis, metabolic syndrome, cardiovascular and neurodegenerative diseases. As a result, a significant amount of effort has been put into comprehending the mechanisms behind its activation and looking for their specific inhibitors. In this review, we primarily focused on phytochemicals that inhibit the inflammasome NLRP3, as well as discuss the defects caused by NLRP3 signaling. We conducted an in-depth research review by searching for relevant articles in the Scopus, Google Scholar, and PubMed databases. By gathering information on phytochemical inhibitors that block NLRP3 inflammasome activation, a complicated balance between inflammasome activation or inhibition with NLRP3 as a key role was revealed in NLRP3-driven clinical situations.

Potential Role of Oxidative Stress in the Pathophysiology of Neurodegenerative Disorders.

Neurodegeneration causes premature death in the peripheral and central nervous system. Neurodegeneration leads to the accumulation of oxidative stress, inflammatory responses, and the generation of free radicals responsible for nervous disorders like amyotrophic lateral sclerosis, Alzheimer's disease, Parkinson's disease, and Huntington's disorders. Therefore, focus must be diverted towards treating and managing these disorders, as it is very challenging. Furthermore, effective therapies are also lacking, so the growing interest of the global market must be inclined towards developing newer therapeutic approaches that can intercept the progression of neurodegeneration. Emerging evidences of research findings suggest that antioxidant therapy has significant potential in modulating disease phenotypes. This makes them promising candidates for further investigation. This review focuses on the role of oxidative stress and reactive oxygen species in the pathological mechanisms of various neurodegenerative diseases, amyotrophic lateral sclerosis, Alzheimer's disease, Parkinson's disease, and Huntington's disorders and their neuroprotection. Additionally, it highlights the potential of antioxidant-based therapeutics in mitigating disease severity in humans and improving patient compliance. Ongoing extensive global research further sheds light on exploring new therapeutic targets for a deeper understanding of disease mechanisms in the field of medicine and biology targeting neurogenerative disorders.

Sepsis epidemiology in Australian and New Zealand children (SENTINEL): protocol for a multicountry prospective observational study.

INTRODUCTION: Sepsis affects 25.2 million children per year globally and causes 3.4 million deaths, with an annual cost of hospitalisation in the USA of US$7.3 billion. Despite being common, severe and expensive, therapies and outcomes from sepsis have not substantially changed in decades. Variable case definitions, lack of a reference standard for diagnosis and broad spectrum of disease hamper efforts to evaluate therapies that may improve sepsis outcomes. This landscape analysis of community-acquired childhood sepsis in Australia and New Zealand will characterise the burden of disease, including incidence, severity, outcomes and cost. Sepsis diagnostic criteria and risk stratification tools will be prospectively evaluated. Sepsis therapies, quality of care, parental awareness and understanding of sepsis and parent-reported outcome measures will be described. Understanding these aspects of sepsis care is fundamental for the design and conduct of interventional trials to improve childhood sepsis outcomes. METHODS AND ANALYSIS: This prospective observational study will include children up to 18 years of age presenting to 12 emergency departments with suspected sepsis within the Paediatric Research in Emergency Departments International Collaborative network in Australia and New Zealand. Presenting characteristics, management and outcomes will be collected. These will include vital signs, serum biomarkers, clinician assessment of severity of disease, intravenous fluid administration for the first 24 hours of hospitalisation, organ support therapies delivered, antimicrobial use, microbiological diagnoses, hospital and intensive care unit length-of-stay, mortality censored at hospital discharge or 30 days from enrolment (whichever comes first) and parent-reported outcomes 90 days from enrolment. We will use these data to determine sepsis epidemiology based on existing and novel diagnostic criteria. We will also validate existing and novel sepsis risk stratification criteria, characterise antimicrobial stewardship, guideline adherence, cost and report parental awareness and understanding of sepsis and parent-reported outcome measures. ETHICS AND DISSEMINATION: Ethics approval was received from the Royal Children's Hospital of Melbourne, Australia Human Research Ethics Committee (HREC/69948/RCHM-2021). This included incorporated informed consent for follow-up. The findings will be disseminated in a peer-reviewed journal and at academic conferences. TRIAL REGISTRATION NUMBER: ACTRN12621000920897; Pre-results.

FDA Approval Summary: Alpelisib for PIK3CA-Related Overgrowth Spectrum.

On April 5, 2022, FDA granted accelerated approval to alpelisib for the treatment of adult and pediatric patients 2 years of age and older with severe manifestations of PIK3CA-related overgrowth spectrum (PROS) who require systemic therapy. Efficacy was evaluated using real-world data (RWD) from EPIK-P1 (NCT04285723), a single-arm clinical study in patients 2 years of age and older with severe or life-threatening PROS who received alpelisib as part of an expanded access program (EAP) for compassionate use. The primary endpoint was confirmed radiologic response rate at week 24 as determined by blinded independent central review (BICR), using volumetric-based criteria given the atypical growth pattern and irregular shape of PROS lesions. Radiologic response was defined as a ≥20% reduction from baseline in the sum of measurable target lesion volume in up to three lesions. Of the 37 patients in the efficacy population, 27% [95% confidence interval (CI), 14-44] had a radiologic response at week 24. Duration of response (DOR) was an additional efficacy outcome measure, and among responders, 60% had a response lasting ≥12 months. Furthermore, supportive clinical documentation suggested early signals of clinical benefit (i.e., improvement in PROS-related signs and symptoms). The most common (≥10%) adverse reactions were diarrhea, stomatitis, and hyperglycemia.

Multifunctional Drug Delivery System: Nanosponges.

In recent years, nanotechnology has been the focus of study for the cure of different diseases, among which nanosponge delivery system is one of a kind. Nano sponges are tiny, highly porous, three-dimensional nanostructures with a size range of 250nm-1µm in an amorphous or crystalline structure. Nanosponges usually act as an excipient or carrier of a drug in the different delivery systems. The type of polymers and cross-linkers, along with their concentration ratio, causes variation in nanosponges's dimension and encapsulation efficiency. Nanosponges have gained prominence in recent times due to their distinct ability to encapsulate both hydrophilic and lipophilic drugs within their internal cavity, thereby improving the solubility of drugs that have low water solubility. Virus-like size helps the nanosponges to circulate within the body without getting eliminated by the immune system until they stick to the targeted part of the body, which makes it the perfect candidate for a targeted drug delivery system and controlled delivery system as well because of its slow drug release property for a more extended period. Cyclodextrin-based nanosponges are the best choice for anticancer drug delivery as their small virus-like diameter helps them in passive targeting by enhancing the enhanced permeability and retention effect, allowing the anticancer drug to stay inside the tumour cell to show more significant therapeutic action on cancer, while for active targeting to the cancerous cell, nanosponges are attached with a ligand on it for receptor binding purpose. It can be used for drug delivery in many major diseases like brain-related diseases, diabetes, cancer, fungal, hypertension, etc., in different dosage forms, like oral, topical, hydrogel, parenteral, etc.

HIV Care Outcomes Among Non-US-Born Persons with Diagnosed HIV Infection, 2019.

Despite the improvements in HIV care outcomes in the United States (US), non-US-born persons continue to be disproportionately affected by HIV. We analyzed National HIV Surveillance System (NHSS) data on HIV diagnoses, stage 3 (AIDS) at diagnosis, linkage to medical care, and viral suppression for non-US-born persons by region of birth (RoB) reported to the (NHSS) in 2020 to determine care outcomes among this population. Overall, a larger proportion of non-US-born persons received a late-stage diagnosis [stage 3 (AIDS)] classification. Among all non-US-born persons, African-born males, Asian-born females, and persons aged 55 + years had the highest proportions of late-stage diagnosis. Despite a late-stage of diagnosis, a higher proportion of non-US-born persons were linked to medical care and were virally suppressed compared to US-born persons. HIV care outcomes varied by RoB and selected characteristics. Knowing the RoB of non-US-born persons is necessary to identify culturally sensitive approaches for prevention planning and increasing testing activities to ultimately increase early diagnosis in this population.

Cyclodextrin Nanosponges: A Revolutionary Drug Delivery Strategy.

Nanosponges are porous solid cross-linked polymeric nanostructures. This study focuses on cyclodextrin-based nanosponges. Nanosponges based on cyclodextrin can form interactions with various lipophilic or hydrophilic compounds. The release of the entrapped molecules can be altered by altering the structure to obtain either a longer or faster release kinetics. The nanosponges might increase the aqueous solubility of weakly water-soluble compounds, develop long-lasting delivery systems, or construct novel drug carriers for nanomedicine. CD-NS (cyclodextrin-based nanosponges) are evolving as flexible and promising nanomaterials for medication administration, sensing, and environmental cleanup. CD-NS are three-dimensional porous structures of cyclodextrin molecules cross-linked by a suitable polymeric network, resulting in a large surface area. This overview covers CD-NS synthesis methods and applications.

Review on Nutritional Potential of Underutilized Millets as a Miracle Grain.

The current situation, which includes changes in eating habits, an increasing population, and the unrestricted use of natural resources, has resulted in a lack of resources that could be used to provide nourishing food to everyone. Natural plant resources are quickly being depleted, so it is necessary to consider new alternatives. In addition to the staple grains of rice and wheat, many other crops are being consumed that need to be utilized to their full potential and have the potential to replace the staple crops. Millets are one of the most important underutilized crops that have the potential to be used as a nutricereal. Millets have a high nutritional value, do not produce acids, do not contain gluten, and can contribute to a healthy diet. Due to a lack of awareness regarding the nutritional value of millets, their consumption is still restricted to the population that adheres to conventional diets and is economically disadvantaged even though millets contain a significant amount of nutrients. Millets are becoming increasingly unpopular due to a lack of processing technologies, food subsidies, and the inconvenience of preparing food with millets. Millets are a Nutricereal rich in carbohydrates, dietary fibers, energy, essential fatty acids, proteins, vitamin B, and minerals such as calcium, iron, magnesium, potassium, and zinc. These nutrients help to protect against post-translational diseases such as diabetes, cancer, cardiovascular disease, and celiac disease, among others. Millets are beneficial for controlling blood pressure, blood sugar level, and thyroid function; however, despite these functional properties, millets consumption has declined. Utilizing millets and other staple food crops to develop alternative food sources has become a new area of focus for businesses in the food industry. In addition, millet consumption can help foster immunity and health, which is essential in strengthening our fight against malnutrition in children and adolescents. In this article, the authors examine the potential of millets in terms of their nutricereal qualities.

Review on Natural Agents as Aromatase Inhibitors: Management of Breast Cancer.

Breast cancer is a prevalent type of cancer that is typically hormone-dependent, caused by estrogen. Aromatase inhibitors are frequently utilised in the treatment of hormonereceptor- positive breast cancer because they prevent the enzyme aromatase from converting androgens to estrogens. Natural medicines with aromatase inhibitory characteristics have attracted interest as potential alternatives or complementary therapy to manufactured medications. This review discusses the function of natural agents as aromatase inhibitors in treating breast cancer. A variety of natural compounds have been investigated for their capacity to inhibit aromatase activity and lower estrogen levels. These agents include resveratrol from red wine and grapes, curcumin from turmeric extract and green teahigh in catechins, and other flavonoids such as genistein, luteolin and quercetin. It has been demonstrated that by decreasing estrogen synthesis, they can slow the growth of breast cancer cells that are dependent on estrogen. However, the clinical evidence supporting their efficacy and safety in breast cancer treatment is inadequate. More research is required to investigate the therapeutic potential of natural medicines, such as aromatase inhibitors, in treating breast cancer. The clinical trials are required to assess their efficacy, appropriate doses, and potential interactions with other therapies. In conclusion, natural aromatase inhibitory drugs are promising adjuncts in the treatment of hormone receptor-positive breast cancer. Their clinical value and safety profile, however, require additional investigation.

Preventing the next fragility fracture: a cross-sectional survey of secondary fragility fracture prevention services worldwide.

BACKGROUND: There has been an increasing awareness of the public health impact of fragility fractures due to osteoporosis and the imperative of addressing this health burden with well-designed secondary fragility fracture prevention services (SFFPS). The objectives of this survey, conducted within the international membership of the Fragility Fracture Network (FFN), were to identify gaps in services and identify the needs for further training and mentorship to improve the quality of SFFPS provided to patients who sustain fragility fractures. METHODS: We conducted an electronic cross-sectional survey of FFN Secondary Fracture Prevention Special Interest Group (SIG) members from April 2021 to June 2021 using SurveyMonkey. The survey questions were developed by four SIG members from New Zealand, Australia, Canada and the Netherlands, who have experience in developing, implementing and evaluating SFFPS. The sampling framework was convenience sampling of all 1162 registered FFN Secondary Fracture Prevention SIG members. Descriptive analyses were performed for all variables and presented as frequencies and percentages. RESULTS: 69 individuals participated in the survey, from 34 different countries over six continents, with a response rate of 6% (69/1162). Almost one-third of respondents (22/69) were from 15 countries within the European continent. Key findings included: (1) 25% of SFFPS only included patients with hip fracture; (2) less than 5% of SFFPS had any mandatory core competencies for training; (3) 38.7% of SFFPS were required to collect key performance indicators; and (4) 9% were collecting patient-reported outcome measures. CONCLUSIONS: This survey identified key areas for improving SFFPS, including: expanding the reach of SFFPS to more patients with fragility fracture, developing international core competencies for health provider training, using key performance indicators to improve SFFPS and including the patient voice in SFFPS development. These findings will be used by the FFN to support SFFPS development internationally.

The mechanism of anti-cancer potential is to be added for searching for new anti-cancer natural products.

Generation of a homozygous CRYAB p.Arg120Gly mutant (UKEi001-A-1) from a human iPSC line.

Variants in CRYAB can lead to desmin-related (cardio-)myopathy (DRM), a genetic muscle disorder with no curative treatment available. We introduced a homozygous CRYAB c.358G > A (p.Arg120Gly) mutation, which is established for the study of DRM in mice, into a donor human induced pluripotent stem cell (hiPSC) line. Control and mutant hiPSCs were tested for karyotype integrity and pluripotency marker expression. HiPSCs could be differentiated into endoderm, ectoderm and cardiomyocytes as a mesodermal derivative in vitro. CRYABhom hiPSC-derived cardiomyocytes developed intracellular CRYAB aggregates, which is a hallmark of DRM. This newly created mutant can be utilized to study DRM and cardiac proteinopathy in a human context.
