RESUMO

BACKGROUND: While utilization of minimally invasive surgery and sentinel lymph node biopsy have increased considerably over time for surgical management of early-stage uterine cancer, practice varies significantly in the United States, with disparities among low-volume centers and patients of Black race. A significant number of counties in the US are without a gynecologic oncologist, and almost half of counties with the highest gynecologic cancer rates lack a local gynecologic oncologist. OBJECTIVE: To evaluate relationships of distance traveled and proximity to gynecologic oncologists with receipt of and racial disparities in the quality of surgical care in patients undergoing hysterectomy for nonmetastatic uterine cancer. STUDY DESIGN: Patients who underwent hysterectomy for nonmetastatic uterine cancer in Kentucky, Maryland, Florida, and North Carolina were identified in 2012-2018 State Inpatient Database and State Ambulatory Surgery Services Database files. County-to-county distances were used for distances traveled and to nearest gynecologic oncologist. Factors associated with receipt of minimally invasive surgery and lymph node dissection were analyzed using multivariable logistic regression models including assessment for interactions of travel for surgery with patient race. RESULTS: Among 21,837 cases, 45.5% lived in a county without a gynecologic oncologist; 55.5% overall traveled to another county for surgery, including 88% of those lacking a local gynecologic oncologist. Patients lacking local access to a gynecologic oncologist in their county who did not travel for surgery were more likely to receive open surgery and no lymph node dissection, and those in counties without access in any surrounding county were even more likely. Among patients in counties without a gynecologic oncologist, those who traveled for surgery had similar likelihood of minimally invasive surgery (71%) but greater likelihood of lymph node dissection (64.7% vs 57.2%) compared to non-travelers. Among counties without a gynecologic oncologist, longer distance traveled was associated with receipt of lymph node assessment. Compared to non-Black patients, Black patients were less likely to undergo minimally invasive surgery (57.0% vs 74.1%). In adjusted regression models controlling for a diagnosis of fibroids, Black race was an independent risk factor for receipt of open surgery. There was a significant interaction of Black race and travel for surgery, with Black patients who lived in counties without a gynecologic oncologist who did not travel facing incrementally lower likelihood of receiving minimally invasive surgery (OR=0.57 vs non-Black patients who traveled for surgery; OR=0.60 as interaction term; p<0.001 for both). Similar disparities in surgical quality by race were noted for Black patients who lived in counties with a gynecologic oncologist who traveled out of county for surgery. CONCLUSIONS: Patients, particularly those of Black race, who lack local access to gynecologic oncologist specialty care benefit from traveling to specialty centers to ensure access to high-quality surgery for nonmetastatic uterine cancer. Further work is needed to ensure equitable and universal access to high-quality care through patient travel or specialist outreach.

RESUMO

Printer source prediction is an important task when examining questioned documents. While some research has provided methods to predict the source printer of documents, with the advent of compatible consumables, printer prediction could become more complex and difficult. Predicting the source printer after replacing cartridges and identifying the source of printer cartridges are unresolved issues that are rarely addressed in current research. Herein, we introduce a novel technique to predict the manufacturer, model, and cartridges of laser printers (i.e., compatible, and original cartridges) used to produce a given document. Document samples produced using eight laser printers and 247 cartridges were collected to establish a dataset. Common manufacturers included HP, Canon, Lenovo, and Epson. After obtaining white-light images and three-dimensional profile images of printed characters, a morphological analysis was conducted by questioned document examiners (QDEs) using microscopy. Microscopic image features across a series of images were also extracted and analyzed using algorithms. Then, six high-dimensional reduction algorithms were used to obtain between- and within-printer variations as well as between- and within-cartridge variations. Finally, we conducted principal component analysis (PCA) and discriminant analysis. For 40 % of the samples, mixed discrimination analysis (MDA) and fixed discrimination analysis (FDA) were employed to predict the manufacturer, model and cartridge of laser printers used to produce the questioned printed document; the remaining 60 % samples comprised the training dataset. In the prediction of manufacturer, model and cartridge, our method achieved mean accuracies of 95.5 %, 97.5 %, and 90.2 %, respectively. Hence, this technique could reasonably aid in predicting the manufacturer, model, and cartridge of a laser printer, even if different cartridges are loaded into printers.

RESUMO

In patients with chronic kidney disease, the uremic toxin indoxyl sulfate (IS) accelerates kidney damage and the progression of cardiovascular disease. IS may contribute to vascular diseases by inducing inflammation in endothelial cells. Luteolin has documented antioxidant and anti-inflammatory properties. This study aimed to investigate the effect of luteolin on IS-mediated reactive oxygen species (ROS) production and intercellular adhesion molecule (ICAM-1) and monocyte chemoattractant protein (MCP-1) expression in EA.hy926 cells and the possible mechanisms involved. IS significantly induced ROS production (by 6.03-fold, p < 0.05), ICAM-1 (by 2.19-fold, p < 0.05) and MCP-1 protein expression (by 2.18-fold, p < 0.05), and HL-60 cell adhesion (by 31%, p < 0.05), whereas, luteolin significantly decreased IS-induced ROS production, ICAM-1 and MCP-1 protein expression, and HL-60 cell adhesion. Moreover, luteolin attenuated IS-induced nuclear accumulation of p65 and c-jun. Luteolin dose-dependently increased heme oxygenase-1 (HO-1) expression and the maximum fold induction of HO-1 by luteolin was 3.68-fold (p < 0.05), whereas, HO-1 knockdown abolished the suppression of ICAM-1 and MCP-1 expression by luteolin. Luteolin may protect against IS-induced vessel damage by inducing HO-1 expression in vascular endothelial cells, which suppresses nuclear factor kappa B (NF-κB) and activator protein 1 (AP-1) mediated ICAM-1 and MCP-1 expression.

RESUMO

The electrochemical NRR to synthesize ammonia is considered as a promising method due to its approvable advantages of zero-pollution emission, feasible reaction proceedings, good safety and easy management. The multiple efforts have been devoted to the exploration of earth-abundant-element-based nanomaterials as high-efficiency electrocatalysts for realizing their industrial applications. Among these, the Ni-based nanomaterials is prioritized as an attractive non-noble-metal electrocatalysts for catalyzing NRR because they are earth-abundance and exceedingly easy to synthesize as well as also delivers the potential of high electrocatalytic activity and durability. In this review, after briefly elucidating the underlying mechanisms of NRR during the electrochemical process, we systematically sum up the recent research progress in representative Ni-based electrocatalysts, including monometallic Ni-based nanomaterials, bimetallic Ni-based nanomaterials, polymetallic Ni-based nanomaterials, etc. In particular, we discuss the effects of physicochemical properties, such as phases, crystallinity, morphology, composition, defects, heteroatom doping, and strain engineering, on the comprehensive performance of the abovementioned electrocatalysts, with the aim of establishing the nanostructure-function relationships of the electrocatalysts. In addition, the promising directions of Ni-based electrocatalysts for NRR are also pointed out and highlighted. The generic approach in this review may expand the frontiers of NRR and provides the inspiration for developing high-efficiently Ni-based electrocatalysts.

RESUMO

BACKGROUND: Chiari malformation type I (CM-1) is a complex disorder in which tonsillar herniation through the foramen magnum manifests with a spectrum of clinical symptoms. This work analyzes morphometric and volumetric characteristics of CM-1 patients. METHODS: With Institutional Review Board (IRB) approval, we retrospectively reviewed a total of 72 adult CM-1 patients and 26 healthy adult volunteers who underwent volumetric magnetic resonance brain imaging. Clinical data was retrospectively extracted from the electronic medical record. We analyzed multi-dimensional morphometric and volumetric features within the posterior cranial fossa and correlated these features with syrinx formation and the decision to undergo surgical decompression. RESULTS: In our study, CM-1 patients had decreased cerebellar, brainstem and 4th ventricular volumes but larger tonsillar volume with increased total tonsillar length. CM-1 patients who underwent surgery had significantly more neural tissue within the cross-sectional area of cisterna magna. Logistic regression demonstrated that combining neural tissue at foramen magnum with cerebellar & 4th ventricular volumes led to great degree of correlation with syrinx formation (AUC 0.911). CONCLUSIONS: Our findings suggest that the amount of tissue at the foramen magnum correlates with CM-1 patients who underwent decompressive surgery, more so than tonsillar length. Additionally, the combination of neural tissue at foramen magnum, cerebellar & 4th ventricular volumes led to great degree of correlation with syrinx formation. Together, these findings suggest that a global compressive phenomenon within the posterior fossa leads to CM-1 symptomatology and syrinx formation.

RESUMO

Matrix metalloproteinase (MMP)-2 and -9, which degrade type IV collagen, are linked to cancer invasion and metastasis. Gene polymorphisms in MMP-2 and MMP-9 can influence their function, impacting cancer development and progression. This study analyzed the association between polymorphisms MMP-2 rs243865 (C-1306T), rs2285053 (C-735T), and MMP-9 rs3918242 (C-1562T) with serum concentrations of these enzymes in upper tract urothelial cancer (UTUC) patients. We conducted a case-control study with 218 UTUC patients and 580 healthy individuals in Taiwan. Genotyping was performed using PCR/RFLP on DNA from blood samples, and MMP-2 and MMP-9 serum levels and mRNA expressions in 30 UTUC patients were measured using ELISA and real-time PCR. Statistical analysis showed that MMP-2 rs2285053 and MMP-9 rs3918242 genotypes were differently distributed between UTUC patients and controls (p = 0.0199 and 0.0020). The MMP-2 rs2285053 TT genotype was associated with higher UTUC risk compared to the CC genotype (OR = 2.20, p = 0.0190). Similarly, MMP-9 rs3918242 CT and TT genotypes were linked to increased UTUC risk (OR = 1.51 and 2.92, p = 0.0272 and 0.0054). In UTUC patients, TT carriers of MMP-2 rs2285053 and MMP-9 rs3918242 showed higher mRNA and protein levels (p < 0.01). These findings suggest that MMP-2 rs2285053 and MMP-9 rs3918242 genotypes are significant markers for UTUC risk and metastasis in Taiwan.

RESUMO

The fermentation process has a significant impact on the aromatic profile of wines, particularly in relation to the difference in fermentation matrix caused by grape varieties. This study investigates the leaching and evolution patterns of aroma compounds in Vitis vinifera L. Marselan and Merlot during an industrial-scale vinification process, including the stages of cold soak, alcohol fermentation, malolactic fermentation, and one-year bottle storage. The emphasis is on the differences between the two varieties. The results indicated that most alcohols were rapidly leached during the cold soak stage. Certain C6 alcohols, terpenes, and norisoprenoids showed faster leaching rates in 'Marselan', compared to 'Merlot'. Some branched chain fatty-acid esters, such as ethyl 3-methylbutyrate, ethyl 2-methylbutyrate, and ethyl lactate, consistently increased during the fermentation and bottling stages, with faster accumulation observed in 'Marselan'. The study combines the Orthogonal Partial Least Squares-Discriminant Analysis (OPLS-DA) model based on odor activity values to elucidate the accumulation of these ethyl esters during bottle storage, compensating for the reduction in fruity aroma resulting from decreased levels of (E)-ß-damascenone. The 'Marselan' wine exhibited a more pronounced floral aroma due to its higher level of linalool, compared to the 'Merlot' wine. The study unveils the distinctive variation patterns of aroma compounds from grapes to wine across grape varieties. This provides a theoretical framework for the precise regulation of wine aroma and flavor, and holds significant production value.

RESUMO

OBJECTIVE: To compare the test-retest reliabilities and minimal detectable change (MDC) of the Short Portable Mental State Questionnaire (SPMSQ) and the Montreal Cognitive Assessment (MoCA) in patients with stroke. METHODS: 63 patients were recruited from 1 medical center. The SPMSQ and MoCA were administered twice, 2 weeks apart. RESULTS: Both measures showed high intraclass correlation coefficients (SPMSQ: 0.87; MoCA: 0.89) and acceptable MDC%s (SPMSQ: 14.8%; MoCA: 19.6%). A small correlation (r = 0.30) was found between the absolute difference and average in each pair of assessments in the SPMSQ, which was close to the criterion of heteroscedasticity. A small practice effect was observed in the MoCA (Cohen's d = 0.30). CONCLUSION: The SPMSQ demonstrated smaller random measurement error and an absence of practice effect. When comparing the psychometric properties of the SPMSQ and MoCA as outcome measures for assessing cognitive function in patients with stroke, the SPMSQ appears to be a more suitable choice than the MoCA.

RESUMO

BACKGROUND/AIM: Hallux valgus (HV) is the most prevalent deformity affecting the forefoot; however, its genetic etiology remains unclear. In the literature, vitamin D receptor (VDR) genotypes have been reported to be associated with the risk of skeletal malformations accompanied by inflammation. This study aimed to examine the hypothesis that VDR genotypes are associated with the risk of HV. MATERIALS AND METHODS: The VDR rs731236, rs1544410, rs2228570 and rs7975232 genotypes of 150 HV patients and 600 non-HV subjects were determined using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) methodology and examined regarding their associations with HV risk. RESULTS: The results showed that none of the genetic frequency distributions of VDR rs731236, rs1544410, rs2228570, or rs7975232 were significant between the HV cases and non-HV controls (p for trend=0.4055, 0.2170, 0.7220, 0.5509, respectively). Additionally, allelic frequency analysis showed that none of the allelic frequencies of VDR rs731236, rs1544410, rs2228570, or rs7975232 were significantly distributed (p=0.2285, 0.1572, 0.9278, and 0.5547, respectively). Furthermore, stratified analysis showed that no correlation was observed between VDR rs731236 and different age groups (either younger or older than 51) or sex (p=0.3953 and p=0.9576). Moreover, no correlation was found between VDR rs731236 genotype and the risk of HV in individuals within subgroups of height, weight, or body mass index (BMI) (p=0.8317, 0.5346, and p=0.8783, respectively). CONCLUSION: VDR rs731236, rs1544410, rs2228570, and rs7975232 may not serve as indicators for a higher risk of HV.

RESUMO

BACKGROUND/AIM: The activity and expression of matrix metalloproteinase-7 (MMP7) have been found to be upregulated in the late stages of endometriosis. However, the contribution of MMP7 genotype to endometriosis has seldom been examined. This study aimed to investigate the role of MMP7 promoter A-181G (rs11568818) and C-153T (rs11568819) genotypes in determining personal susceptibility to endometriosis in a Taiwanese cohort. PATIENTS AND METHODS: In this hospital-based case-control study, MMP7 genotypes were analyzed in 153 endometriosis and 636 individuals without endometriosis using typical polymerase chain reaction-restriction fragment length polymorphism methodology. RESULTS: The statistical analysis revealed that MMP7 rs11568818 genotypes were differentially distributed between the endometriosis and control groups (p for trend=0.0048). Specifically, the MMP7 rs11568818 homozygous variant GG was associated with endometriosis risk compared to the wild-type AA genotype (OR=4.59, 95% CI=1.46-14.48, p=0.0136). However, the MMP7 rs11568818 heterozygous variant AG was not associated with endometriosis risk (OR=1.57, 95% CI=0.97-2.53, p=0.0854). The frequency of than variant allele G of MMP7 rs11568818 was 12.7% in the endometriosis group, significantly higher than the 7.2% observed in the control group (OR=1.90, 95% CI=1.27-2.82, p=0.0021). CONCLUSION: MMP7 rs11568818 GG genotype was found to be a novel marker for endometriosis risk in Taiwanese.

RESUMO

BACKGROUND: Previous investigations have shown a positive relationship between baseball pitching velocity and the kinetic chain involved in pitching motion. However, no study has examined the influence of finger characteristics on pitching velocity and rate of spin via a sensor-embedded baseball. METHODS: Twenty-one pitchers volunteered and were recruited for this study. An experimental baseball embedded with a force sensor and an inertial measurement unit was designed for pitching performance measurement. Finger length and strength were measured as dependent variables. Spin rate and velocity were independent variables. Pearson product-moment correlations (r) and intraclass correlation coefficients (ICCs) determined the relationship between finger characteristics and pitching performance. RESULTS: Finger length discrepancy, two-point pinch strength, index finger RFD (rate of force development), middle finger impulse, and force discrepancy had significant correlations with spin rate (r = 0.500~0.576, p ≤ 0.05). Finger length discrepancy, two-point pinch, three-point pinch strength, index and middle finger RFD, middle finger impulse, and force combination had significant correlations with fastball pitching velocity (r = 0.491~0.584, p ≤ 0.05). CONCLUSIONS: Finger length discrepancy, finger pinch strength, and pitching finger force including maximal force and RFD may be factors that impact fastball spin rate and fastball pitching velocity.

RESUMO

Atezolizumab plus bevacizumab is a standard of care, first-line therapy for advanced hepatocellular carcinoma (HCC). Myeloid and T regulatory cells are key immunosuppressive cell types within the hepatic tumor microenvironment associated with clinical resistance to atezolizumab and bevacizumab therapy for HCC and overall poor prognosis. Therapeutic targeting of TIGIT, which is highly expressed in these cells, with tiragolumab may overcome the immunosuppressive environment and improve clinical benefit, a hypothesis supported by positive efficacy signals in the Phase Ib/II MORPHEUS-Liver study. This paper describes the rationale and design of IMbrave152/SKYSCRAPER-14, a randomized, double-blind, placebo-controlled Phase III study comparing atezolizumab and bevacizumab with tiragolumab or placebo in patients with HCC and no prior systemic treatment.Clinical Trial Registration: NCT05904886 (ClinicalTrials.gov).


This research study is designed to test a new treatment combination for liver cancer, specifically for patients whose cancer cannot be removed with surgery or has spread. The treatment involves three medications: atezolizumab, bevacizumab and tiragolumab.Atezolizumab and bevacizumab are already used together as a standard treatment for liver cancer. Tiragolumab is designed to block the TIGIT receptor, which is normally involved in holding back the immune cells that would attack the tumor. Because tiragolumab may restore the immune response against the tumor, adding tiragolumab might make the treatment more effective.The study is being done worldwide and includes patients who have not received any previous systemic treatment for their advanced liver cancer. Patients participating in the study will be randomly placed into two groups. One group will receive the new combination of three medications, while the other group will receive the standard treatment of two medications plus a placebo (a treatment with no active ingredient). The main goal is to see if the new combination helps patients live longer and slows the cancer's growth compared with the standard treatment. Safety and how patients feel during the treatment are also important parts of the study.

RESUMO

The Phenome-wide association studies (PheWAS) have become widely used for efficient, high-throughput evaluation of relationship between a genetic factor and a large number of disease phenotypes, typically extracted from a DNA biobank linked with electronic medical records (EMR). Phecodes, billing code-derived disease case-control status, are usually used as outcome variables in PheWAS and logistic regression has been the standard choice of analysis method. Since the clinical diagnoses in EMR are often inaccurate with errors which can lead to biases in the odds ratio estimates, much effort has been put to accurately define the cases and controls to ensure an accurate analysis. Specifically in order to correctly classify controls in the population, an exclusion criteria list for each Phecode was manually compiled to obtain unbiased odds ratios. However, the accuracy of the list cannot be guaranteed without extensive data curation process. The costly curation process limits the efficiency of large-scale analyses that take full advantage of all structured phenotypic information available in EMR. Here, we proposed to estimate relative risks (RR) instead. We first demonstrated the desired nature of RR that overcomes the inaccuracy in the controls via theoretical formula. With simulation and real data application, we further confirmed that RR is unbiased without compiling exclusion criteria lists. With RR as estimates, we are able to efficiently extend PheWAS to a larger-scale, phenome construction agnostic analysis of phenotypes, using ICD 9/10 codes, which preserve much more disease-related clinical information than Phecodes.

RESUMO

C-type lectins (CTLs) are a family of carbohydrate-binding proteins and an important component of mosquito saliva. Although CTLs play key roles in immune activation and viral pathogenesis, little is known about their role in regulating dengue virus (DENV) infection and transmission. In this study, we established a homozygous CTL16 knockout Aedes aegypti mutant line using CRISPR/Cas9 to study the interaction between CTL16 and viruses in mosquito vectors. Furthermore, mouse experiments were conducted to confirm the transmission of DENV by CTL16-/- A. aegypti mutants. We found that CTL16 was mainly expressed in the medial lobe of the salivary glands (SGs) in female A. aegypti. CTL16 knockout increased DENV replication and accumulation in the SGs of female A. aegypti, suggesting that CTL16 plays an important role in DENV transmission. We also found a reduced expression of immunodeficiency and Janus kinase/signal transducer and activator of transcription pathway components correlated with increased DENV viral titer, infection rate, and transmission efficiency in the CTL16 mutant strain. The findings of this study provide insights not only for guiding future investigations on the influence of CTLs on immune responses in mosquitoes but also for developing novel mutants that can be used as vector control tools.

RESUMO

Terpenoids are important contributors to the aroma of grapes and wines. Grapes contain terpenoids in both volatile free form and non-volatile glycosidic form, with the latter being more abundant. Glycosylated terpenoids are deemed as latent aromatic potentials for their essential role in adding to the flowery and fruity bouquet of wines. However, the transcriptional regulatory mechanism underlying glycosylated terpenoid biosynthesis remains poorly understood. Our prior study identified an AP2/ERF transcription factor, VviERF003, through DNA pull-down screening using the promoter of terpenoid glycosyltransferase VviGT14 gene. This study demonstrated that both genes were co-expressed and synchronized with the accumulation of glycosylated monoterpenoids during grape maturation. VviERF003 can bind to the VviGT14 promoter and promote its activity according to yeast one-hybrid and dual-luciferase assays. VviERF003 upregulated VviGT14 expression in vivo, leading to increased production of glycosylated monoterpenoids based on the evidence from overexpression or RNA interference in leaves, berry skins, and calli of grapes, as well as tomato fruits. Additionally, VviERF003 and VviGT14 expressions and glycosylated monoterpenoid levels were induced by ethylene in grapes. The findings suggest that VviERF003 is ethylene-responsive and stimulates glycosylated monoterpenoid biosynthesis through upregulating VviGT14 expression.

RESUMO

Data curation for a hospital-based cancer registry heavily relies on the labor-intensive manual abstraction process by cancer registrars to identify cancer-related information from free-text electronic health records. To streamline this process, a natural language processing system incorporating a hybrid of deep learning-based and rule-based approaches for identifying lung cancer registry-related concepts, along with a symbolic expert system that generates registry coding based on weighted rules, was developed. The system is integrated with the hospital information system at a medical center to provide cancer registrars with a patient journey visualization platform. The embedded system offers a comprehensive view of patient reports annotated with significant registry concepts to facilitate the manual coding process and elevate overall quality. Extensive evaluations, including comparisons with state-of-the-art methods, were conducted using a lung cancer dataset comprising 1428 patients from the medical center. The experimental results illustrate the effectiveness of the developed system, consistently achieving F1-scores of 0.85 and 1.00 across 30 coding items. Registrar feedback highlights the system's reliability as a tool for assisting and auditing the abstraction. By presenting key registry items along the timeline of a patient's reports with accurate code predictions, the system improves the quality of registrar outcomes and reduces the labor resources and time required for data abstraction. Our study highlights advancements in cancer registry coding practices, demonstrating that the proposed hybrid weighted neural-symbolic cancer registry system is reliable and efficient for assisting cancer registrars in the coding workflow and contributing to clinical outcomes.

RESUMO

BACKGROUND: Inappropriate medication utilization among older adults is a pressing concern in the United States, owing to its high prevalence and the consequential detrimental impact it engenders. The adverse effects stemming from the inappropriate use of medication may be unequally borne by racial/ethnic minority populations, calling for greater efforts towards promoting equity in healthcare. The study objective was to assess the cost-effectiveness of Medication Therapy Management (MTM) services among Medicare beneficiaries and across racial/ethnic groups. METHODS: Medicare administrative data from 2016 to 2017 linked to Area Health Resources Files were used to analyze Medicare fee-for-service patients aged 65 or above with continuous Parts A/B/D coverage. The intervention group included new MTM enrollees in 2017; the control group referred to patients who met the general MTM eligible criteria but did not enroll in 2016 or 2017. The 2 groups were matched using a propensity score method. Effectiveness was evaluated as the proportion of appropriate medication utilization based on performance measures developed by the Pharmacy Quality Alliance. Costs were computed as total healthcare costs from Medicare perspective. A multivariable net benefit regressions with a classic linear model and Bayesian analysis were utilized. Net benefit was calculated based on willingness-to-pay thresholds at various multiples of the gross domestic product in 2017. Three-way interaction terms among dummy variables for MTM enrollment, 2017, and racial/ethnic minority groups were incorporated in a difference-in-differences study design. RESULTS: After adjusting for patient characteristics, the findings indicate that MTM receipt was associated with incremental net benefit among each race and ethnicity. For instance, the net benefit of MTM among the non-Hispanic White patients was $2498 (95% confidence interval = $1609, $3386) at a willingness-to-pay value of $59,908. The study found no significant difference in net benefits for MTM services between minority and White patients. CONCLUSION: The study provides evidence that MTM is a cost-effective tool for managing medication utilization among the Medicare population. However, MTM may not be cost-effective in reducing racial/ethnic disparities in medication utilization in the short term. Further research is needed to understand the long-term cost-effectiveness of MTM on racial/ethnic disparities.

RESUMO

Previously, we documented the synthesis and assessed the biological effects of chalcones containing selenium against HT-29 human colorectal adenocarcinoma cells, demonstrating their significant potential. As research on selenium-containing flavonoids remains limited, this article outlines our design and synthesis of three selenium-based flavonols and three 2-styrylchromones. We conducted evaluations of these compounds to determine their impact on human lung cancer cells (A549, H1975, CL1-0, and CL1-5) and their influence on normal lung fibroblast MRC5 cells. Additionally, we included selenium-based chalcones in our testing for comparative purposes. Our findings highlight that the simplest compound, designated as compound 1, exhibited the most promising performance among the tested molecules.

RESUMO

BACKGROUND/AIM: Renal cell carcinoma (RCC) presents a formidable clinical challenge due to its aggressive behavior and limited therapeutic options. Matrix metalloproteinase-8 (MMP-8) has recently emerged as a potential biomarker and therapeutic target for various cancers. However, the genetic involvement of MMP-8 in RCC has remained largely obscure. This study aimed to elucidate the role of MMP-8 genotypes in RCC susceptibility. MATERIALS AND METHODS: The polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) technique was employed to scrutinize the genotypes of MMP-8 C-799T (rs11225395), Val436Ala (rs34009635), and Lys460Thr (rs35866072) among 118 RCC patients and 590 controls. Furthermore, potential associations between MMP-8 genotypes and age, sex, smoking, alcohol consumption, hypertension, diabetes, and family history status in relation to RCC risk were assessed. RESULTS: No significant disparities in the distribution of MMP-8 rs11225395, rs34009635, and rs35866072 genotypes were observed between the RCC case and control cohorts (p>0.05). Individuals with CT and TT genotypes at MMP-8 rs11225395 exhibited 0.86- and 0.80-fold RCC risks, respectively (OR=0.57-1.31 and 0.42-1.55, p=0.5585 and 0.6228, respectively). Intriguingly, hypertensive individuals carrying the MMP-8 rs11225395 CT or TT genotype demonstrated an elevated risk for RCC compared to those with wild-type CC genotype (p=0.0440). No interactions of MMP-8 genotypes with age, sex, smoking, alcohol consumption, or diabetes status were evident (all p>0.05). No significant association was discerned for MMP-8 rs34009635 or rs35866072 genotypes. CONCLUSION: MMP-8 genotypes appear to have a modest influence on individual susceptibility to RCC. Hypertensive patients with the CT or TT MMP-8 rs11225395 genotype may have an elevated risk of RCC.
