Adipocentric origin of the common cardiometabolic complications of obesity in the young up to the very old: pathophysiology and new therapeutic opportunities

Obesity is a multifactorial chronic disease characterized by an excess of adipose tissue, affecting people of all ages. In the last 40 years, the incidence of overweight and obesity almost tripled worldwide. The accumulation of “visceral” adipose tissue increases with aging, leading to several cardio-metabolic consequences: from increased blood pressure to overt arterial hypertension, from insulin-resistance to overt type 2 diabetes mellitus (T2DM), dyslipidemia, chronic kidney disease (CKD), and obstructive sleep apnea. The increasing use of innovative drugs, namely glucagon-like peptide-1 receptor agonists (GLP1-RA) and sodium-glucose cotransporter-2 inhibitors (SGLT2-i), is changing the management of obesity and its related cardiovascular complications significantly. These drugs, first considered only for T2DM treatment, are now used in overweight patients with visceral adiposity or obese patients, as obesity is no longer just a risk factor but a critical condition at the basis of common metabolic, cardiovascular, and renal diseases. An adipocentric vision and approach should become the cornerstone of visceral overweight and obesity integrated management and treatment, reducing and avoiding the onset of obesity-related multiple risk factors and their clinical complications. According to recent progress in basic and clinical research on adiposity, this narrative review aims to contribute to a novel clinical approach focusing on pathophysiological and therapeutic insights.

Mobile Technology Use in Clinical Research Examining Challenges and Implications for Health Promotion in South Africa: Mixed Methods Study.

The use of mobile technologies in fostering health promotion and healthy behaviors is becoming an increasingly common phenomenon in global health programs. Although mobile technologies have been effective in health promotion initiatives and follow-up research in higher-income countries and concerns have been raised within clinical practice and research in low- and middle-income settings, there is a lack of literature that has qualitatively explored the challenges that participants experience in terms of being contactable through mobile technologies. This study aims to explore the challenges that participants experience in terms of being contactable through mobile technologies in a trial conducted in Soweto, South Africa. A convergent parallel mixed methods research design was used. In the quantitative phase, 363 young women in the age cohorts 18 to 28 years were contacted telephonically between August 2019 and January 2022 to have a session delivered to them or to be booked for a session. Call attempts initiated by the study team were restricted to only 1 call attempt, and participants who were reached at the first call attempt were classified as contactable (189/363, 52.1%), whereas those whom the study team failed to contact were classified as hard to reach (174/363, 47.9%). Two outcomes of interest in the quantitative phase were "contactability of the participants" and "participants' mobile number changes," and these outcomes were analyzed at a univariate and bivariate level using descriptive statistics and a 2-way contingency table. In the qualitative phase, a subsample of young women (20 who were part of the trial for ≥12 months) participated in in-depth interviews and were recruited using a convenience sampling method. A reflexive thematic analysis approach was used to analyze the data using MAXQDA software (version 20; VERBI GmbH). Of the 363 trial participants, 174 (47.9%) were hard to reach telephonically, whereas approximately 189 (52.1%) were easy to reach telephonically. Most participants (133/243, 54.7%) who were contactable did not change their mobile number. The highest percentage of mobile number changes was observed among participants who were hard to reach, with three-quarters of the participants (12/16, 75%) being reported to have changed their mobile number ≥2 times. Eight themes were generated following the analysis of the transcripts, which provided an in-depth account of the reasons why some participants were hard to reach. These included mobile technical issues, coverage issues, lack of ownership of personal cell phones, and unregistered number. Remote data collection remains an important tool in public health research. It could, thus, serve as a hugely beneficial mechanism in connecting with participants while actively leveraging the established relationships with participants or community-based organizations to deliver health promotion and practice.

Cisplatin-Based Combination Therapy for Enhanced Cancer Treatment.

Cisplatin, a primary chemotherapeutic drug, is of great value in the realm of tumor treatment. However, its clinical efficacy is strictly hindered by issues, such as drug resistance, relapse, poor prognosis, and toxicity to normal tissue. Cisplatin-based combination therapy has garnered increasing attention in both preclinical and clinical cancer research for its ability to overcome resistance, reduce toxicity, and enhance anticancer effects. This review examines three primary co-administration strategies of cisplatin-based drug combinations and their respective advantages and disadvantages. Additionally, seven types of combination therapies involving cisplatin are discussed, focusing on their main therapeutic effects, mechanisms in preclinical research, and clinical applications. This review also discusses future prospects and challenges, aiming to offer guidance for the development of optimal cisplatin-based combination therapy regimens for improved cancer treatment.

Anticaries and Antigingivitis Properties of Cannabinoid-Containing Oral Health Products: A Review.

To evaluate the anticaries and antigingivitis properties of cannabinoid-containing oral health products. A systematic research strategy was employed. Specific search terms were used, including "Cannabinoids AND dental caries," "Cannabinoids AND oral health," "Cannabinoids AND dental plaque," "Cannabinoids AND gingivitis AND periodontitis," "Cannabinoids AND S. mutans," "Cannabidiol AND oral health," and "Cannabidiol AND oral biofilm." The search was conducted in PubMed, Cochrane, and EBSCO Host databases. The search yielded a total of 73 articles, out of which 15 articles (20.5%) were relevant to the scope of this systematic review. Among the relevant articles, only eight (10.9%) directly addressed the research question. The findings from these articles suggest that cannabinoids have the potential to reduce the metabolism of cariogenic bacteria, specifically Streptococcus mutans, and decrease the number of bacterial colonies in dental plaque. In vitro studies also demonstrated a significant inhibitory effect of cannabinoids on oral biofilms and create a considerable inhibitory zone of growth when investigated on oral biofilms in vitro. Furthermore, CBD exhibited antibacterial properties against Porphyromonas gingivalis, a primary pathogen associated with periodontal disease. The current review shows insufficient data to conclude on the anticaries and antigingivitis effects of cannabinoids. Despite extensive research on their systemic therapeutic benefits, their oral health impact remains underexplored, lacking clinical trials and primary research.

Psychometric properties and factor structure of the traditional Chinese version of the Community Integration Questionnaire-Revised in traumatic brain injury survivors.

This study aimed to translate and validate the traditional Chinese version of the Community Integration Questionnaire-Revised (TC-CIQ-R) in patients with traumatic brain injury (TBI). We included participants aged ≥20 years and diagnosed as having TBI for ≥6 months from neurosurgical clinics. The 18-item TC-CIQ-R, Participation Measure - 3 Domains, 4 Dimensions (PM-3D4D), Extended Glasgow Outcome Scale (GOSE), and Taiwanese Quality of Life After Brain Injury (TQOLIBRI) were completed. The sample included 180 TBI survivors (54% male, mean age 47 years) of whom 87% sustained a mild TBI. Exploratory factor analysis extracted four factors - home integration, social integration, productivity, and electronic social networking - which explained 63.03% of the variation, after discarding the tenth item with a factor loading of 0.25. For criterion-related validity, the TC-CIQ-R was significantly correlated with the PM-3D4D; convergent validity was exhibited by demonstrating the associations between the TC-CIQ-R and TQOLIBRI. Known-group validity testing revealed significant differences in the subdomain and total scores of the TC-CIQ-R between participants with a mean GOSE score of ≤6 and >7 (all P < 0.001). The TC-CIQ-R exhibited acceptable Cronbach's α values (0.68-0.88). We suggest the 17-item TC-CIQ-R as a valid tool for rehabilitation professionals, useful for both clinical practice and research in assessing community integration levels following TBI.

Early Serial Assessment of Aggregate Vasoactive Support and Mortality in Cardiogenic Shock: Insights from the Critical Care Cardiology Trials Network Registry.

Background: Associations of early changes in vasoactive support with cardiogenic shock (CS) mortality remain incompletely defined. Methods: The Critical Care Cardiology Trials Network is a multicenter registry of cardiac intensive care units (CICUs). Patients admitted with CS (2018-2023) had vasoactive dosing assessed at 4 and 24 hours (h) from CICU admission and quantified by the vasoactive-inotropic score (VIS). Prognostic associations of VIS at both timepoints, as well as change in VIS from 4h to 24h, were examined. Interaction testing was performed by mechanical circulatory support (MCS) status. Results: Among 3,665 patients, 82% had a change in VIS <10, with 7% and 11% having a ≥10point increase and decrease from 4h to 24h, respectively. The 4h and 24h VIS were each associated with CICU mortality (13%- 45% and 11%-73% for VIS <10 to ≥40, respectively; ptrend <0.0001 for each). Stratifying by the 4h VIS, changes in VIS from 4h to 24h had a graded association with mortality, ranging from a 2-to->4-fold difference in mortality comparing those with a ≥10-point increase to a ≥10-point decrease in VIS (p-trend <0.0001). The change in VIS alone provided good discrimination of CICU mortality (C-statistic 0.72 [95% CI 0.70-0.75]), and improved discrimination of the 24h SOFA score (0.76 [95% CI 0.74-0.78] from 0.72 [95% CI 0.69-0.74]) and the clinician-assessed SCAI stage (0.77 [95% CI 0.75-0.79] from 0.72 [95% CI 0.70-0.74]). Although present in both groups, the mortality risk associated with VIS was attenuated in patients managed with vs. without MCS (OR per 10-point higher 24h VIS: 1.36 [1.23-1.49] vs. 1.84 [1.69-2.01]; p-interaction<0.0001). Conclusions: Early changes in the magnitude of vasoactive support in CS are associated with a gradient of risk for mortality. These data suggest that early VIS trajectory may improve CS prognostication, with potential to be leveraged for clinical decision-making and research applications in CS.

An Empirical Evaluation of Prompting Strategies for Large Language Models in Zero-Shot Clinical Natural Language Processing: Algorithm Development and Validation Study.

Large language models (LLMs) have shown remarkable capabilities in natural language processing (NLP), especially in domains where labeled data are scarce or expensive, such as the clinical domain. However, to unlock the clinical knowledge hidden in these LLMs, we need to design effective prompts that can guide them to perform specific clinical NLP tasks without any task-specific training data. This is known as in-context learning, which is an art and science that requires understanding the strengths and weaknesses of different LLMs and prompt engineering approaches. The objective of this study is to assess the effectiveness of various prompt engineering techniques, including 2 newly introduced types-heuristic and ensemble prompts, for zero-shot and few-shot clinical information extraction using pretrained language models. This comprehensive experimental study evaluated different prompt types (simple prefix, simple cloze, chain of thought, anticipatory, heuristic, and ensemble) across 5 clinical NLP tasks: clinical sense disambiguation, biomedical evidence extraction, coreference resolution, medication status extraction, and medication attribute extraction. The performance of these prompts was assessed using 3 state-of-the-art language models: GPT-3.5 (OpenAI), Gemini (Google), and LLaMA-2 (Meta). The study contrasted zero-shot with few-shot prompting and explored the effectiveness of ensemble approaches. The study revealed that task-specific prompt tailoring is vital for the high performance of LLMs for zero-shot clinical NLP. In clinical sense disambiguation, GPT-3.5 achieved an accuracy of 0.96 with heuristic prompts and 0.94 in biomedical evidence extraction. Heuristic prompts, alongside chain of thought prompts, were highly effective across tasks. Few-shot prompting improved performance in complex scenarios, and ensemble approaches capitalized on multiple prompt strengths. GPT-3.5 consistently outperformed Gemini and LLaMA-2 across tasks and prompt types. This study provides a rigorous evaluation of prompt engineering methodologies and introduces innovative techniques for clinical information extraction, demonstrating the potential of in-context learning in the clinical domain. These findings offer clear guidelines for future prompt-based clinical NLP research, facilitating engagement by non-NLP experts in clinical NLP advancements. To the best of our knowledge, this is one of the first works on the empirical evaluation of different prompt engineering approaches for clinical NLP in this era of generative artificial intelligence, and we hope that it will inspire and inform future research in this area.

Sishen Pill and its active phytochemicals in treating inflammatory bowel disease and colon cancer: an overview

The incidence of inflammatory bowel disease (IBD) and the associated risk of colon cancer are increasing globally. Traditional Chinese medicine (TCM) treatment has unique advantages. The Sishen Pill, a common Chinese patented drug used to treat abdominal pain and diarrhea, consists mainly of Psoraleae Fructus, Myristicae Semen, Euodiae Fructus, and Schisandra Chinensis. Modern research has confirmed that Sishen Pill and its active secondary metabolites, such as psoralen, myristicin, evodiamine, and schisandrin, can improve intestinal inflammation and exert antitumor pharmacological effects. Common mechanisms in treating IBD and colon cancer mainly include regulating inflammation-related signaling pathways such as nuclear factor-kappa B, mitogen-activated protein kinase, phosphatidylinositol 3-kinase, NOD-like receptor heat protein domain-related protein 3, and wingless-type MMTV integration site family; NF-E2-related factor 2 and hypoxia-inducible factor 1α to inhibit oxidative stress; mitochondrial autophagy and endoplasmic reticulum stress; intestinal immune cell differentiation and function through the Janus kinase/signal transducer and activator of transcription pathway; and improving the gut microbiota and intestinal barrier. Overall, existing evidence suggests the potential of the Sishen pill to improve IBD and suppress inflammation-to-cancer transformation. However, large-scale randomized controlled clinical studies and research on the safety of these clinical applications are urgently required.

Enrolment of the first paediatric cohort into the Australian lupus registry and biobank: A single-centre experience.

We aim to report on the feasibility of establishment of the first paediatric cohort as part of the longitudinal database of the Australian Lupus Registry and Biobank (ALRB) and to describe the enrolment data with a focus on clinical characteristics, serological data, treatment strategies and patient/parent-reported outcome measures. All patients under the age of 18years with a diagnosis of systemic lupus erythematosus (SLE) attending the paediatric rheumatology service of a single, tertiary hospital were identified. Patients were enrolled in the ALRB if they met ≥4/11 of the American College of Rheumatology (ACR) 1997 SLE classification criteria or the Systemic Lupus International Collaborating Clinics (SLICC) 2012 classification criteria. Enrolment data including demographics, clinical characteristics, serological profiles, disease activity and damage assessments were recorded. Peds-QL Rheumatology and General Modules were used to assess patient and parent-reported outcomes. Twenty-seven patients were eligible for inclusion, with 26 patients (96%) consenting for enrolment. Twenty-five patients (92%) consented for biobanking. Twenty patients (77%) were female. The median age at enrolment was 16years (interquartile range (IQR) 13.7, 17.4). The median disease duration from diagnosis was 3.2years (IQR 1.4, 5.3). Sixteen patients (62%) had synovitis, 16 (62%) had cutaneous involvement, 4 (15%) had serositis, 17 (65%) had haematological involvement and 7 (27%) had renal involvement at enrolment. Nineteen patients (73%) were prescribed at least two disease-modifying anti-rheumatic medications (DMARDs). Hydroxychloroquine (n = 22, 85%) and mycophenolate mofetil (n = 9, 35%) were the most commonly prescribed DMARDs. The median SLEDAI-2K score was 2 (IQR 2, 4). Six patients (23%) had active disease (SLEDAI-2K ≥6) at enrolment. Three patients (11.5%) had reported damage using the SLICC/ACR Damage Index. Twenty-three children (88%) and eighteen parents (69%) completed the Paediatric Quality of Life Inventory. Quality of life scores reported across domains of physical, emotional, social and school functioning at enrolment were comparable to previously studied paediatric cohorts with SLE and other chronic diseases. We have established our centre as the first paediatric participating site of the ALRB, providing contemporary data on the clinical characteristics, serological profile and health-related quality of life outcomes of Australian children with SLE. Paediatric involvement with this national registry will provide a unique perspective for future clinical and scientific research. Collection of Australian-specific paediatric longitudinal data will also enable a broader understanding of SLE within a multicultural Australian population.

Effect of silver nanoparticles formulated by Silybum marianum on menopausal urinary incontinence in ovariectomized rats

Abstract Urinary incontinence is the major sign of menopause genitourinary syndrome and is usually related to the sexual dysfunctions. Fifty percent of menopausal women have menopausal urinary tract. Menopause genitourinary syndrome is a hypoestrogenic condition with external sexual, urological, and genital implications. The production of estrogen decline after menopause is an important parameter for urinary incontinence. Recently, nanotechnology has been applied as a remedial option for the genitourinary disease treatment. Silver nanoparticles were mediated by the Silybum marianum aqueous extract for the menopausal urinary incontinence treatment in ovariectomized rats in the current experiment. The green-formulated AgNPs@Silybum marianum were characterized by FT-IR, TEM, SEM, and UV–Vis. The SEM findings prove the spherical morphology with size of 15–60 nm. The ovariectomized rats were treated by AgNPs@Silybum marianum (5 and 20 µg/kg/day) for 56 days. According to the results, AgNPs@Silybum marianum increased the urinary bladder weight and reduced the body weights in comparison with the untreated rats. AgNPs@Silybum marianum rats indicated a dose-dependent amelioration for the acetylcholine contraction index. AgNPs@Silybum marianum also ameliorated the levels of serum 17β-estradiol, urinary bladder hydroxyproline, triglyceride, cholesterol, LDL, HDL, ALP, AST, and ALT in the ovariectomized rats. Based on the experiment results, the recent formulation may be applied for the menopausal urinary incontinence treatment in humans after performing the clinical research.

The study of chamomile (Matricaria recutita)

In Western culture, chamomile is a well-known plant. Hippocrates, Galen, as well as Asclepius are just a few of the ancient figures who wrote upon their medical use. Paediatricians always want to know if a child's caretaker has used over-the-counter medications or herbal items, and this information should be included in any medication history. Children with GI issues including colic, dyspepsia, and diarrhoea, as well as skin ailments like dermatitis, are frequently treated with chamomile. According to clinical research, chamomile may be beneficial in the management of diarrhoea, colic, and atopic dermatitis. Children don't experience many negative effects. But use chamomile with caution if your child has allergies to ragweed, asters, or chrysanthemums.

Progress in research and treatment of immune checkpoints in breast cancer

Breast cancer is the most common malignant tumor among women often involving the toxicity of conventional chemotherapy alongside organ-specific side effects. As immunotherapeutic agents in anti-tumor, new immune checkpoints are constantly being dug and discovered. The role of immune checkpoint inhibitors in the process of tumor immune evasion has assumed increasing significance. Currently, clinical research outcomes on immunotherapy for breast cancer vary, reflecting diverse efficacy profile of immune checkpoints. This article provides an overview of immune checkpoint suppression therapy, and track the evolving research and therapeutic application of immune checkpoints related to breast cancer.

Clinical status and perspective on the application of immunotherapy combined with chemotherapy in advanced non-small cell lung cancer: a review.

The therapeutic landscape of advanced non-small cell lung cancer (NSCLC) has been significantly improved by developing immunotherapy represented by programmed cell death 1 (PD-1) and programmed cell death ligand 1 (PD-L1) immune checkpoint inhibitors (ICI). Furthermore, immunotherapy combined with chemotherapy is an essential treatment strategy for driver-negative advanced NSCLC, especially in a population with PD-L1 <50%, and leads to long-term survival in the entire population regardless of the PD-L1 expression status. However, specific challenges must be overcome, including how to use immunotherapy with chemotherapy in clinics. Furthermore, the application of immunotherapy with chemotherapy in populations such as elderly patients and patients with brain metastases, oligometastases, epidermal growth factor receptor (EGFR) gene mutation, anaplastic lymphoma kinase (ALK) gene rearrangements, and other driver gene-positive populations must be further explored. The biomarkers associated with immunotherapy and chemotherapy are still unclear, and the search for predictive biomarkers can contribute toward more precise and personalized immunotherapy. Furthermore, treatment strategies after immunotherapy and chemotherapy resistance are of significant focus clinically, and clinical studies with multiple combination therapy strategies are ongoing. Therefore, based on the reported status of immunotherapy combined with chemotherapy for advanced NSCLC, this study conducted a comprehensive literature review by searching keywords "PD-1 and PD-L1, immune checkpoint inhibitor (ICI), and NSCLC" in MEDLINE, major conferences, and major clinical research projects to elucidate the therapeutic efficacy of immunotherapy combined with chemotherapy as the current first-line treatment approach for various types of NSCLC patients. Additionally, it addresses several pressing challenges associated with immunotherapy combined with chemotherapy, including enhancing treatment response and survival rate in specific patient populations and identifying potential biomarkers.

Spinal Meningiomas: A Comprehensive Review and Update on Advancements in Molecular Characterization, Diagnostics, Surgical Approach and Technology, and Alternative Therapies.

Spinal meningiomas are the most common intradural, extramedullary tumor in adults, yet the least common entity when accounting for all meningiomas spanning the neuraxis. While traditionally considered a benign recapitulation of their intracranial counterpart, a paucity of knowledge exists regarding the differences between meningiomas arising from these two anatomic compartments in terms of histopathologic subtypes, molecular tumor biology, surgical principles, long-term functional outcomes, and recurrence rates. To date, advancements at the bench have largely been made for intracranial meningiomas, including the discovery of novel gene targets, DNA methylation profiles, integrated diagnoses, and alternative systemic therapies, with few exceptions reserved for spinal pathology. Likewise, evolving clinical research offers significant updates to our understanding of guiding surgical principles, intraoperative technology, and perioperative patient management for intracranial meningiomas. Nonetheless, spinal meningiomas are predominantly relegated to studies considering non-specific intradural extramedullary spinal tumors of all histopathologic types. The aim of this review is to comprehensively report updates in both basic science and clinical research regarding intraspinal meningiomas and to provide illustrative case examples thereof, thereby lending a better understanding of this heterogenous class of central nervous system tumors.

Fine Modeling and Mechanical Analysis of Human Lumbar Spine

This paper has created a skeletal model of the human lumbar spine and proved its effectiveness. Simulated scenarios when the human body is moving, including forward bending, backward extension, left bending, and left rotation. Compare range of motion, vertebral displacement, annulus fibrosus displacement, endplate displacement, nucleus pulposus displacement, annulus fibrosus stress, endplate stress, nucleus pulposus stress, and cortical bone stress. The model of this study was based on anatomical principles for detailed drawing of the human lumbar spine. ROMs under different physiological motions including flexion, extension, and lateral bending with 300N preload and 3.75N·m moment were measured under the normal finite element model. The degrees of flexion of L1-S1 were 17.204°. The degrees of extension of L1-S1 were 13.959°. The degrees of lateral bending of L1-S1 were 10.326°, axial rotation were 6. 466°. The maximum stress for intervertebral disc flexion is 1.4285MPa. The maximum stress of the extension intervertebral disc is 1.1296MPa. The maximum stress of the intervertebral disc with lateral bending is 1.7589MPa. The maximum stress of the axial rotating intervertebral disc is 1. 1698MPa. After comparing with classical literature, the model of this study meets clinical research standards and may be a good choice for clinical surgical analysis.

Efficacy of a virtual nursing simulation-based education to provide psychological support for patients affected by infectious disease disasters: a randomized controlled trial.

Virtual simulation-based education for healthcare professionals has emerged as a strategy for dealing with infectious disease disasters, particularly when training at clinical sites is restricted due to the risk of infection and a lack of personal protective equipment. This research evaluated a virtual simulation-based education program intended to increase nurses' perceived competence in providing psychological support to patients affected by infectious disease disasters. The efficacy of the program was evaluated via a randomized controlled trial. We recruited 104 nurses for participation in the study and allocated them randomly and evenly to an experimental group and a control group. The experimental group was given a web address through which they could access the program, whereas the control group was provided with a web address that directed them to text-based education materials. Data were then collected through an online survey of competence in addressing disaster mental health, after which the data were analyzed using the Statistical Package for the Social Sciences(version 23.0). The analysis showed that the experimental group's disaster mental health competence (F = 5.149, p =.026), problem solving process (t = 3.024, p =.003), self-leadership (t = 2.063, p =.042), learning self-efficacy (t = 3.450, p =.001), and transfer motivation (t = 2.095, p =.039) significantly statistically differed from those of the control group. A virtual nursing simulation-based education program for psychological support can overcome limitations of time and space. The program would also be an effective learning resource during infectious disease outbreaks. This Korean clinical trial was retrospectively registered (21/11/2023) in the Clinical Research Information Service ( https://cris.nih.go.kr ) with trial registration number KCT0008965.

Yoga-based lifestyle intervention for healthy ageing in older adults: a two-armed, waitlist randomized controlled trial with multiple primary outcomes.

Yoga-based clinical research has shown considerable promise in varied ageing-related health outcomes in older adults. However, robust frameworks have yet to be used in intervention research to endorse yoga as a healthy ageing intervention to test the multidimensional construct of healthy ageing. This was an assessor-masked, randomized controlled trial conducted among 258 sedentary, community-dwelling older adults aged 60-80years, randomly allocated to 26-week yoga-based intervention (YBI) (n = 132) or waitlist control (WLC) (n = 126). The effectiveness of YBI was assessed through two separate global statistical tests, generalized estimating equations and rank sum-based test, against a comprehensive healthy aging panel comprised of ten markers representing the domains of physiological and metabolic, cognitive, physical capability, psychological, and social well-being. The secondary outcomes were individual primary marker scores, Klotho, inflammatory markers, and auxiliary blood markers. We could establish the healthy aging effect of the 26-week YBI over WLC using two models of global statistical test (GEE, β = 0.29; 95% CI = 0.20 to 0.38, p < 0.001), and rank sum-based test (β = 0.28, 95% CI = 0.19 to 0.36, p < 0.001). There were also significant improvements in direction of benefit at individual levels of all the aging markers. Exploratory evaluation with adopted indices from contemporary clinical trials also validated the potential of YBI for healthy aging; HATICE adapted composite score (mean difference =  - 0.18; 95% CI =  - 0.26 to - 0.09, p < 0.001) and healthy ageing index (mean difference =  - 0.33; 95% CI =  - 0.63 to - 0.02, p = 0.03). The global effect of YBI across multiple ageing-related outcomes provides a proof of concept for further large-scale validation. The findings hold a great translational value given the accelerated pace of population aging across the globe. Trial registration: CTRI/2021/02/031373.

The Mechanism of Action and Clinical Research Progress of Gastrodin in the Treatment of Vertigo

Gastrodin is a phenolic glycoside with the chemical name of 4-hydroxybenzyl alcohol-β-D-glucopyranoside, which is the main bioactive component of Gastrodia in China. Gastrodin has low toxicity, good sedative and sleeping effects, can effectively dilate the body's blood vessels, increase myocardial blood flow, have a protective effect on the body's nerve cells, and play a role in regulating the excitation and inhibition of the cerebral cortex in the central nervous system, improving vestibular function, anti-inflammatory, antioxidant and other effects, thereby improving the clinical dizziness and other symptoms of patients. Gastrodin injection has good clinical effect in the treatment of vertigo, and no obvious adverse reactions have been observed. Compared with gastrodin alone in the treatment of vertigo, the combination with promethazine, diphenhydramine, betahistine and other drugs can effectively improve the treatment rate and reduce the incidence of related side effects.

Metformin: A Dual-Role Player in Cancer Treatment and Prevention.

Cancer continues to pose a significant global health challenge, as evidenced by the increasing incidence rates and high mortality rates, despite the advancements made in chemotherapy. The emergence of chemoresistance further complicates the effectiveness of treatment. However, there is growing interest in the potential of metformin, a commonly prescribed drug for type 2 diabetes mellitus (T2DM), as an adjuvant chemotherapy agent in cancer treatment. Although the precise mechanism of action of metformin in cancer therapy is not fully understood, it has been found to have pleiotropic effects, including the modulation of metabolic pathways, reduction in inflammation, and the regulation of cellular proliferation. This comprehensive review examines the anticancer properties of metformin, drawing insights from various studies conducted in vitro and in vivo, as well as from clinical trials and observational research. This review discusses the mechanisms of action involving both insulin-dependent and independent pathways, shedding light on the potential of metformin as a therapeutic agent for different types of cancer. Despite promising findings, there are challenges that need to be addressed, such as conflicting outcomes in clinical trials, considerations regarding dosing, and the development of resistance. These challenges highlight the importance of further research to fully harness the therapeutic potential of metformin in cancer treatment. The aims of this review are to provide a contemporary understanding of the role of metformin in cancer therapy and identify areas for future exploration in the pursuit of effective anticancer strategies.
