Traditional Medicinal Plants in Cancer Therapy and Chemoprevention: A Review of Preclinical and Clinical Studies

Abstract: Cancer has become a significant public health concern in the past few decades, and it is now the world's second cause of death. Although there are various types of cancer treatments, such as chemotherapy, immune therapy, radiation, hormone therapy, gene editing, etc., they all have adverse reactions and significant failings. Plant and dietary mixtures have been utilized to treat malignant growth over the entire course of time. These mixtures likewise might be helpful in anticipation of malignant growth. Chemoprevention is cancer prevention that makes use of plant phytochemicals and synthetic substances. Because of their reduced toxicity and inexpensive cost, phytoconstituents are gaining much interest in chemoprevention effectiveness. As a result, the chemopreventive power of naturally occurring phytochemicals is of great interest. Populace studies propose that a decreased gamble of malignant growth is related to the maximum usage of vegetables and natural products. This review summarised the latest research on plants and their chemicals targeting various malignancies and their mechanisms of cancer suppression by modulating multiple signaling pathways. It provides a small outline of green synthesized nanoparticles, an emerging area to combat cancer.

Comparative study of phenotypic-based detection assays for carbapenemases in Acinetobacter baumannii

BackgroundAcinetobacter baumannii is a serious health concern worldwide, causing high mortality rates and limited medical therapy options. Carbapenem resistance is a significant problem in Acinetobacter baumannii isolates. The synthesis of acquired carbapenemases, such as oxacillinases, IMP, NDM, VIM, and KPC enzymes, causes carbapenem resistance. MethodsA total of 106 non-repetitive, Acinetobacter baumannii isolates were collected from four major hospitals in Bahrain including 78 carbapenem-resistant Acinetobacter baumannii (CRAB), and 28 carbapenem-susceptible Acinetobacter baumannii (CSAB) isolates. Three phenotypic tests were investigated in this study: including CARBA NP, modified carbapenem inactivation method (mCIM)/EDTA-CIM (eCIM), and modified Hodge test (MHT). ResultsCARBA NP was positive in 50 tested CRAB isolates (100%), and the sensitivity was 100%. The MHT was positive in 73/106 isolates (68.8%), while the sensitivity and specificity of the MHT were 77.6% and 100%. Moreover, only 38/106 (35.8%) isolates were positive for mCIM/eCIM. The sensitivity and specificity of mCIM were 40.4% and 100%. ConclusionCARBA NP was ideal for phenotypic detection of carbapenemase production, followed by MHT. The m/eCIM demonstrated a lower detection rate in CRAB. Consequently, combining tests would be more accurate. The mCIM/eCIM can easily distinguish between MBLs and serine-carbapenemases due to the frequent co-production of these enzymes in A. baumannii. In hospital setups where molecular characterization tests are not available, CARBA NP seems to be an alternative test in combination with MHT or mCIM/eCIM.

Preventive effects of Bifidobacterium lactis Probio-M8 on ovalbumin-induced food allergy in mice

Food allergy is a significant public health concern globally. Certain probiotics have been found to enhance food allergy by regulating immune-microbe interactions in animal models and patients. However, the effects of Bifidobacterium lactis Probio-M8 (Probio-M8) on food allergy have not been thoroughly investigated. The present study examined the anti-allergic properties of Probio-M8, particularly in relation to immune response and gut microbiota composition. Results demonstrate that oral administration of Probio-M8 effectively mitigated the allergy symptoms triggered by ovalbumin (OVA) by ameliorating the morphological damage in the jejunum, reducing OVA-specific IgE and histamine levels in the serum, and suppressing Th2 cytokines (interleukin (IL) 4 and IL-13) while increasing Th1 cytokines (interferon (IFN) γ) and regulatory T (Treg) cytokines (IL-10 and transforming growth factor (TGF) β1) in the culture supernatants of splenic cells. Furthermore, Probio-M8 effectively altered the diversity and composition of gut microbiota, particularly the relative abundances of Akkermansia_muciniphila in OVA-induced mice. Compared to the OVA group, the Probio-M8 group showed a decrease in the relative abundance of Akkermansia_muciniphila. In conclusion, Probio-M8 demonstrates the potential to alleviate food allergy by regulating the Th1/Th2 response and modulating gut microbiota, thereby offering a novel therapeutic strategy for patients with food allergy.

Reviewing chronic ailments: predicting diseases with a multi-symptom approach

The integration of machine learning (ML) techniques is now indispensable in healthcare, especially in addressing the challenges posed by chronic illnesses, which present a significant global health concern due to their unpredictable nature. This study compares ML techniques employed in the diagnosis and treatment of chronic conditions such as diabetes, liver disease, thyroid disease, breast cancer, heart disease, Alzheimer’s disease, and others. Two primary criteria guided the selection of diseases under investigation. Firstly, those extensively studied with ML methods, and secondly, those leveraging ML models to resolve issues or yield promising results. The research concludes that in real-time clinical practice, there is no universally proven method for selecting the optimal course of action due to each method’s unique advantages and disadvantages. While a hybrid technique may exhibit slightly slower speed growth, it holds the potential to enhance the accuracy and performance of a model.

A rare manifestation of serum sickness after common krait envenomation in a patient treated with polyvalent anti-snake venom in India: Presentation and challenges

ABSTRACT Envenomation from snakebites is a significant public health concern in the Southeast Asian region resulting in considerable mortality and morbidity. Anti-snake venom (ASV) despite being the only rescue can bring forth several acute and delayed adverse effects. Among them, serum sickness is a late manifestation after treatment with ASV that presents after 5–14 days of treatment. However, there is no specific definition to diagnose serum sickness or proven treatment. Here, we present a case of serum sickness to provide an insight into this unventured zone, briefing the presentation, treatment and probable reason for serum sickness and its prevention after common krait envenomation and treatment with polyvalent ASV in India.

Exploring the potential of genetic analysis in historical blood spots for patients with iodine-deficient goiter and thyroid carcinomas in Switzerland and Germany (1929–1989)

Iodine deficiency-induced goiter continues to be a global public health concern, with varying manifestations based on geography, patient’s age, and sex. To gain insights into clinical occurrences, a retrospective study analyzed medical records from patients with iodine deficiency-induced goiter or thyroid cancer who underwent surgery at the Community Hospital in Riehen, Switzerland, between 1929 and 1989. Despite today’s adequate iodine supplementation, a significant risk for iodine-independent goiter remains in Switzerland, suggesting that genetic factors, among others, might be involved. Thus, a pilot study exploring the feasibility of genetic analysis of blood spots from these medical records was conducted to investigate and enhance the understanding of goiter development, potentially identify genetic variations, and explore the influence of dietary habits and other environmental stimuli on the disease.Blood prints from goiter patients’ enlarged organs were collected per decade from medical records. These prints had been made by pressing, drawing, or tracing (i.e., pressed and drawn) the removed organs onto paper sheets. DNA analysis revealed that its yields varied more between the prints than between years. A considerable proportion of the samples exhibited substantial DNA degradation unrelated to sample collection time and DNA mixtures of different contributors. Thus, each goiter imprint must be individually evaluated and cannot be used to predict the success rate of genetic analysis in general. Collecting a large sample or the entire blood ablation for genetic analysis is recommended to mitigate potential insufficient DNA quantities. Researchers should also consider degradation and external biological compounds’ impact on the genetic analysis of interest, with the dominant contributor anticipated to originate from the patient’s blood.

Air pollution aggravates renal ischaemia-reperfusion-induced acute kidney injury.

Chronic kidney disease (CKD) has emerged as a significant global public health concern. Recent epidemiological studies have highlighted the link between exposure to fine particulate matter (PM2.5) and a decline in renal function. PM2.5 exerts harmful effects on various organs through oxidative stress and inflammation. Acute kidney injury (AKI) resulting from ischaemia-reperfusion injury (IRI) involves biological processes similar to those involved in PM2.5 toxicity and is a known risk factor for CKD. The objective of this study was to investigate the impact of PM2.5 exposure on IRI-induced AKI. Through a unique environmentally controlled setup, mice were exposed to urban PM2.5 or filtered air for 12 weeks before IRI followed by euthanasia 48 h after surgery. Animals exposed to PM2.5 and IRI exhibited reduced glomerular filtration, impaired urine concentration ability, and significant tubular damage. Further, PM2.5 aggravated local innate immune responses and mitochondrial dysfunction, as well as enhancing cyclic GMP-AMP synthase-stimulator of interferon genes (cGAS-STING) pathway activation. This increased renal senescence and suppressed the anti-ageing protein klotho, leading to early fibrotic changes. In vitro studies using proximal tubular epithelial cells exposed to PM2.5 and hypoxia/reoxygenation revealed heightened activation of the STING pathway triggered by cytoplasmic mitochondrial DNA, resulting in increased tubular damage and a pro-inflammatory phenotype. In summary, our findings imply a role for PM2.5 in sensitising proximal tubular epithelial cells to IRI-induced damage, suggesting a plausible association between PM2.5 exposure and heightened susceptibility to CKD in individuals experiencing AKI. Strategies aimed at reducing PM2.5 concentrations and implementing preventive measures may improve outcomes for AKI patients and mitigate the progression from AKI to CKD. © 2024 The Authors.

Prevalence of Vitamin D Deficiency among Libyan Pregnant Women

Vitamin D deficiency is a common health concern worldwide. We aim to assess the prevalence of vitamin D deficiency among sample of Libyan pregnant patients. A cross-sectional retrospective study was conducted in May 2024 to examine vitamin D status level among Libyan pregnant women. Data on vitamin D status were analyzed from available sample for 97 women collected from different gynecological clinics in Tripoli city, Libya. Our results showed that the average vitamin D level in all women was 15.72±10.5 ng/mL. Pregnant women showed differences in BMI, parity, and daily sunlight exposure. The number of women was higher in the insufficient group, and their mean vitamin D level was lower (15.13±2.34) than sufficient groups (33.95±20.71 ng/mL). Supportive programme should be implemented and more widely promoted, and physicians should be better informed about the program's content during pregnancy.

Point-of-care STI testing in rural settings: A feasibility project.

Sexually transmitted infections (STIs) continue to be a health concern in the United States, particularly in rural settings. Point-of-care (POC) STI testing is useful in overcoming access barriers in these settings. The purpose of this project was to implement POC STI testing to increase access to care in rural settings and test the feasibility of this model. Six mobile health clinics were implemented by a nurse-led team in three rural communities in the Blackbelt region of Alabama utilizing the Binx IO® to test for chlamydia and gonorrhea. Mobile clinic volunteers participated in focus groups to determine provider satisfaction with clinic workflow. The mobile health clinics were a feasible way to increase access to STI testing in rural settings with reported provider and client satisfaction in work flow.

Enhancing hepatocellular carcinoma management: prognostic value of integrated CCL17, CCR4, CD73, and HHLA2 expression analysis

PurposeHepatocellular carcinoma (HCC) is a critical global health concern, with existing treatments benefiting only a minority of patients. Recent findings implicate the chemokine ligand 17 (CCL17) and its receptor CCR4 as pivotal players in the tumor microenvironment (TME) of various cancers. This investigation aims to delineate the roles of CCL17 and CCR4 in modulating the tumor’s immune landscape, assessing their potential as therapeutic interventions and prognostic markers in HCC.Methods873 HCC patients post-radical surgery from 2008 to 2012 at Zhongshan Hospital, Fudan University were retrospectively examined. These individuals were stratified into a training cohort (n = 354) and a validation cohort (n = 519). Through immunohistochemical analysis on HCC tissue arrays, the expressions of CCL17, CCR4, CD73, CD47, HHLA2, and PD-L1 were quantified. Survival metrics were analyzed using the Cox model, and a prognostic nomogram was devised via R software.ResultsThe investigation confirmed the presence of CCL17 and CCR4 within the cancerous and stromal compartments of HCC tissues, associating their heightened expression with adverse clinical markers and survival outcomes. Notably, the interplay between CD73 and CCR4 expression in tumor stroma highlighted a novel cellular entity, CCR4 + CD73 + stromal cells, impacting overall and relapse-free survival. A prognostic nomogram amalgamating these immunological markers and clinical variables was established, offering refined prognostic insights and aiding in the management of HCC. The findings suggest that reduced CCR4 and CCR4 + CD73 + cell prevalence may forecast improved outcomes post-TACE.ConclusionThis comprehensive evaluation of CCR4, CCL17, and associated markers introduces a nuanced understanding of the HCC immunological milieu, proposing CCR4 + CD73 + stromal cells as critical to HCC pathogenesis and patient stratification.

Bioguided Fractionation of Phyllanthus spp.: Unveiling Anticancer Potential through Metabolomic Correlation and ADMETox Insights.

Cancer remains a significant global health concern, with mortality rates steadily rising and prompting an urgent search for effective treatments. This study focuses on the medicinal properties of plants from the Phyllanthus genus, specifically Phyllanthus amarus and Phyllanthus niruri, which have shown promise in traditional medicine. Through bioguided fractionation using preparative high-performance liquid chromatography (HPLC), bioactive compounds were isolated and identified using ultra-performance liquid chromatography coupled to time-of-flight mass spectrometry (UHPLC-QTOF-MSE) and nuclear magnetic resonance (NMR) spectroscopy. Chemometric analyses such as principal component analysis (PCA) aided in understanding metabolite distribution. Biological assays demonstrated cytotoxic activities of specific fractions against cancer cell lines, notably the PhyN 4n fraction from P. niruri, which induced S-phase cell cycle arrest and apoptosis in HL60 cells. These findings underscore the anticancer potential of Phyllanthus species and lay the groundwork for future drug development efforts. The study's integration of advanced analytical techniques, chemometrics, and biological assays provides valuable insights for harnessing natural products in the fight against cancer.

Residential segregation and summertime air temperature across 13 northeastern U.S. states: Potential implications for energy burden

Abstract High ambient summertime temperatures are an increasing health concern with climate change. This is a particular concern for minoritized households in the United States, for which differential energy burden may compromise adaptive capacity to high temperatures. Our research question was: Do minoritized groups experience hotter summers than the area average, and do non-Hispanic white people experience cooler summers? Using a fine-scaled spatiotemporal air temperature model and U.S. census data, we examined local (within-county) differences in warm season cooling degree days (CDDs) by ethnoracial group as a proxy for local energy demand for space cooling across states of the northeast and mid-Atlantic U.S. in 2003–2019. Using state-specific regression models adjusted for year and county, we found that Black and Latino people consistently experienced more CDDs, non-Hispanic white people experienced fewer CDDs, and Asian populations showed mixed results. We also explored a concentration-based measure of residential segregation for each ethnoracial group as one possible pathway towards temperature disparities. We included the segregation measure as a smooth term in a regression model adjusted for county and year. The results were nonlinear, but higher concentrations of white people were associated with lower annual CDDs and higher concentrations of Latino people were associated with higher annual CDDs than the county average. Concentrations for Black and Asian people were nonmonotonic, sometimes with bowed associations. These findings suggest that present-day residential segregation, as modeled by spatially smoothed ethnoracial subgroup concentrations, may contribute to summertime air temperature disparities and influence adaptive capacity. We hope these findings can support place-based interventions, including targeting of energy insecurity relief programs.

MassARRAY: a high-throughput solution for rapid detection of foodborne pathogens in real-world settings

IntroductionBacterial foodborne pathogens pose a substantial global public health concern, prompting government agencies and public health organizations to establish food safety guidelines and regulations aimed at mitigating the risk of foodborne illness. The advent of DNA-based amplification coupled with mass spectrometry, known as MassARRAY analysis, has proven to be a highly precise, sensitive, high-throughput, and cost-effective method for bacterial detection. This study aimed to develop, validate, and evaluate a MassARRAY-based assay for the detection and identification of significant enteropathogenic bacteria.MethodsThe MassARRAY-based assay was developed for the detection of 10 crucial bacterial foodborne pathogens, including Campylobacter coli, Campylobacter jejuni, Clostridium perfringens, Escherichia coli, Enterococcus faecalis, Enterococcus faecium, Listeria monocytogenes, Salmonella spp., Shigella spp., and Staphylococcus aureus. The assay was optimized using the reference gDNA (n = 19), followed by validation using gDNA (n = 85) of reference and laboratory isolates. Additionally, the evaluation of the assay’s reaction using a mixture of gDNA from all nine targeted species was performed. The limit of detection of the developed MassARRAY-based assay was determined using bacterial cells. Moreover, the validation method for field samples was evaluated by comparing it with standard microbiological testing methods routinely analyzed.ResultsThe developed MassARRAY-based assay demonstrated 100% concordance with known bacterial pure cultures. The assay’s reaction using a mixture of gDNA from all nine targeted species revealed the MassARRAY’s capability to detect all targeted species in a single assay with the lowest concentration of 1 ng/μL of gDNA. The limits of detection of the assay range from 357 ± 101 to 282,000 ± 79,196 cells. Moreover, the validation of the assay in field samples revealed a 100% correlation between the data obtained from the standard microbiological method and the MassARRAY-based assay.DiscussionThese findings suggested that the developed MassARRAY-based assay exhibited the excellence in high-throughput detection of foodborne bacterial pathogens with high accuracy, reliability, and potential applicability within real-world field samples.
