RESUMEN

BACKGROUND: The association between coffee and caffeine intake and the risk of COPD and lung function has not been thoroughly discussed in Americans, with subgroup and threshold effects remaining unclear. OBJECTIVES: This study investigated the association between coffee and caffeine consumption and the risk of chronic obstructive pulmonary disease (COPD) as well as lung function utilizing data from the NHANES 2007-2012. METHODS: We assessed the associations of coffee and caffeine consumption with the risk of COPD and lung function parameters, including FEV1 and FVC, adjusting for common demographic and disease characteristics in a cross-sectional analysis of NHANES data. RESULTS: A total of 9763 participants were included in the study, and 592 were diagnosed with COPD. Multivariate regression models revealed positive associations between coffee and caffeine consumption and the risk of COPD and lung function. Subgroup analyses stratified by sex, DM, hypertension status, and smoking habits identified potential effect modifiers as well as inflection points from threshold effect examinations. CONCLUSIONS: The results of this cross-sectional study indicated significant positive correlations between coffee and caffeine consumption and the risk of COPD. Additionally, positive correlations between exposure variables and FEV1 and FVC were detected. Among the stratification factors, smoking status exhibited the most potential for modifying effects. Future practices and research are needed to validate the results and explore the underlying mechanisms.

RESUMEN

BACKGROUND: Haemorrhoids are a common chronic anorectal disease, and haemorrhoidectomy is the standard treatment for advanced (grade III and IV) haemorrhoids. Warm water sitz has commonly been used to stimulate urination, cleanse wounds, and decrease pain. Although urinary retention and pain usually occur within the first 24 h after surgery, the warm water sitz bath is provided 24 h after haemorrhoidectomy, which might be a missed opportunity to optimize the quality and efficiency of the care provided. OBJECTIVE: To investigate the effect of early warm water sitz bath on the day of haemorrhoidectomy surgery on preventing urinary retention and reducing wound pain. DESIGN: This was a longitudinal double-blind study with a permuted block randomization design. SETTING(S): This study was conducted in a surgical ward of a medical center. An average of 18 patients receiving hemorrhoid surgery in that ward every month. PARTICIPANTS: A total of 64 participants (32 each in the experimental and control groups) were enrolled. (The first recruitment date is January 16, 2020.) METHODS: Patients who received haemorrhoidectomy for grade III or IV haemorrhoids from January to December 2020 were enrolled. The experimental and control groups received the same conventional treatment and care before the haemorrhoidectomy. The experimental group started warm-water sitz bath 6 h after the surgery, and the control group started warm water sitz bath on post-haemorrhoidectomy day 1 as usual. Urinary retention was defined as use of Foley catheter during the hospital stay or remaining urine volume ≧ 300 ml using the bladder scan. A numerical rating scale was used to rate the pain level. Each participant was evaluated 6 times in total until hospital discharge. The data were analysed by descriptive statistics, chi-square test, and independent samples t test. Generalized estimating equations and intention to treat were used to identify changes in urinary retention and pain over time and missing data, respectively. RESULTS: There was no significant difference in the degree of change in the number of people with urinary retention between groups. A change in the wound pain index was noted; the study group had a statistically significant lower pain score than the control group (B = -0.81, 95 % CI: -1.44 to -0.18). CONCLUSIONS: Early warm water sitz bath was a safe and effective strategy to decrease post-haemorrhoidectomy pain, but not urinary retention. Nurses could provide early warm water sitz bath for post-haemorrhoidectomy patients' comfort. REGISTRATION: ClinicalTrials.gov ID: NCT04535765.

RESUMEN

Turmeric is widely used worldwide, and there are many examples of its use in treating hepatobiliary diseases. The gut-liver axis is a bidirectional relationship between gut microorganisms and the liver that is closely related to the pathogenesis of hepatobiliary diseases. This review systematically summarizes the components of turmeric. It links the studies on turmeric affecting gut microorganisms to its effects on liver and biliary diseases to explain the potential mechanism of turmeric's regulation of the gut-liver axis. Besides, ethnopharmacology, phytochemicals, and clinical adverse events associated with turmeric have been researched. Furthermore, turmeric is a safe agent with good clinical efficacy and without apparent toxicity at a certain amount. By summarizing the influence of turmeric on the liver by regulating the gut-liver axis, especially the gut microbiota, it provides a preclinical basis for using turmeric as a safe and effective therapeutic agent for the prevention and treatment of hepatobiliary diseases based on the gut-liver axis. However, more efforts should be made to exploit its clinical application further.

RESUMEN

BACKGROUND: The association between dietary selenium(Se) intake and type 2 diabetes mellitus (T2DM) remains controversial. The present study aimed to investigate this association using data from the National Health and Nutrition Examination Survey (NHANES) database for the years 2007-2012. METHODS: Three thousand seventy three individuals aged 20 years and above were eligible for inclusion in this cross-sectional study. The average age of the participants was 50.74 years and the proportions of males and females were nearly equal (49.12% vs. 50.88%). The odds ratios (OR) of the association between dietary Se intake (log2-transformed) and T2DM were examined through the multivariate logistic regression model. Subgroup analyses were conducted based on age, sex, and thyroid autoimmunity to assess the potential impact of these variables on the relationship. Fitted smoothing curves and threshold effect analysis were conducted to describe the nonlinear relationship. RESULTS: In the fully adjusted model, a significant positive association between Se intake and T2DM was observed (OR = 1.49, 95% CI: 1.16, 1.90, p = 0.0017). After stratifying the data by age, sex, and thyroid autoimmunity, a significant positive association between Se intake and T2DM was observed in individuals under 65 years of age, males, and those with negative thyroid autoimmunity. A two-segment linear regression model was analyzed for sex stratification, revealing a threshold effect in males with an inflection point of 90.51 µg, and an inverted U-shaped relationship in females with an inflection point of 109.90 µg, respectively. CONCLUSIONS: The present study found a positive relationship between Se intake and the prevalence of T2DM. This association is particularly significant in younger individuals, males, and those with negative thyroid autoimmunity. Our results should be validated in future large prospective studies in different populations.

RESUMEN

PURPOSE: Multiple materials are found in the root canal after fiber-post cementation. The layer of a bioceramic-based (BC) sealer may affect the bond strength (σBS) of the fiber post in the root canal. The purpose of this study was to employ multilayer compos-ite-disk models in diametral compression to investigate whether the bond strength between a fiber post and root dentin can be in-creased by the application of a primer on the BC sealer. MATERIALS AND METHODS: The multilayers of materials in the root canal required 3D finite-element (FE) stress analyses (FEA) to pro-vide precise σBS values. First, BC sealer was characterized using x-ray powder diffraction (XRD) to determine when the sealer com-pletely set and the types of crystals formed to select which primer to apply to the sealer. We selected a 10-methacryloyloxydecyl dihydrogen phosphate (10-MDP)-based primer to treat the BC sealer before post cementation. Ultra-highspeed (UHS) imaging was utilized to analyze the crack initiation interface. The obtained failure force was used in FE analysis to calculate σBS. RESULTS: UHS imaging validated the fracture interface at the post-dentin junction as FEA simulations predicted. σBS values of the fiber posts placed with various material combinations in the root canal were 21.1 ± 3.4 (only cement/ post), 22.2 ± 3.4 (BC sealer/cement/post) and 28.6 ± 4.3 MPa (10-MDP primer treated BC sealer/cement/post). The 10-MDP-treated BC sealer exhibited the highest σBS (p < 0.05). CONCLUSION: The multilayer composite disk model proved reliable with diametral compression testing. The presence of BC sealer in the root canal does not reduce σBS of the fiber post. Conditioning the BC sealer layer with 10-MDP primer before fiber-post cemen-tation increases σBS.

RESUMEN

Turmeric, a traditional medicinal herb, is commonly used as a dietary and functional ingredient. This study aimed to investigate the effect of turmeric polysaccharides (TPs) on intestinal immunity and gut microbiota in cyclophosphamide (Cy)-induced immunosuppressed BALB/c mice. We verified that the oral administration of TPs-0 and TPs-3 (200 and 400 mg/kg, bw) improved thymus and spleen indexes, increased the whole blood immune cells (WBC) and lymph count index, and stimulated the secretion of serum immunoglobulin IgG. More importantly, TPs-0 and TPs-3 could repair intestinal immune damage and reduce intestinal inflammation. The specific mechanism is ameliorating the intestinal pathological damage, promoting CD4+ T cell secretion, regulating the expression of related cytokines, and reducing the level of critical proteins in the NF-κB/iNOS pathway. Interestingly, the intake of TPs-0 and TPs-3 significantly increased the content of short-chain fatty acids (SCFAs). Moreover, TPs-0 and TPs-3 relieved the intestinal microbiota disorder via the proliferation of the abundance of Lactobacillus and Bacteroides and the inhibition of Staphylococcus. Cumulatively, our study suggests that TPs-0 and TPs-3 can relieve intestinal immune damage by repairing the immune barrier and regulating intestinal flora disorders. TPs have potential applications for enhancing immunity as a functional food.

RESUMEN

Chronic obstructive pulmonary disease (COPD) is now considered among the top three contributors to mortality globally. There is limited understanding surrounding the contribution of magnesium to the progression of COPD. This survey aims to evaluate the connection between dietary magnesium intake and both lung function and COPD prevalence among the US population. The research comprised 4865 participants in the National Health and Nutrition Examination Survey (NHANES) program conducted from 2007 to 2012. To evaluate the association between dietary magnesium intake and lung function as well as COPD, the study conducted multiple regression analyses, stratified analyses, and smoothed curves. In this study, we explored the relationship between higher magnesium intake and higher FEV1 [ß = 0.21 (95% CI 0.12, 0.30)] and FVC [ß = 0.25 (95% CI 0.14, 0.36)] after accounting for all potential confounding factors. We demonstrated a relationship between increased magnesium intake and reduced odds of developing COPD [OR = 0.9993 (95% CI 0.9987, 1.0000)]. The results of stratified analyses further indicated that the relationship between magnesium intake and the risk of COPD is more pronounced in the 40-60 age group and males. The study demonstrated positive associations between the intake of dietary magnesium and both FEV1 and FVC. Additionally, an adverse relationship between magnesium intake and the prevalence of COPD was also observed, suggesting that supplementation with magnesium may be a practical approach to preventing and managing COPD.

RESUMEN

ETHNOPHARMACOLOGICAL RELEVANCE: An herbal pair is a classic form of clinical dispensing in Traditional Chinese Medicine (TCM), often used in prescriptions to enhance the effect or reduce potential side effects. It is the smallest component unit of Chinese medicine prescription and an essential bridge between Chinese medicine and prescription. Curcumae Rhizoma (called Ezhu in Chinese) is a representative TCM herb that promotes blood circulation and removes blood stasis. It has been used in Chinese medicine for thousands of years. Ezhu is generally used in clinical applications as a part of a "drug pair" to treat heartburn, stomach pain, tumour, amenorrhea and abdominal pain caused by blood stasis, qi stagnation and injury. AIMS OF THE REVIEW: This review aims to summarize the latest and comprehensive situation of the biological activity and clinical application of drug pairs containing Ezhu, find the law of Ezhu compatibility application, and discuss the rationalization of Ezhu drug compatibility. For Ezhu, herb pairs to provide a theoretical basis for clinical research in TCM and serve as a research foundation for developing new drugs. MATERIALS AND METHODS: Using a self-built prescription database and Apriori algorithm for association rule mining. A systematic search for studies on herb pairs containing Ezhu was carried out by using the internet databases of PubMed, CNKI, Baidu Scholar, Google Scholar and Web of Science, as well as other relevant textbooks, reviews and documents (e.g. Chinese Pharmacopoeia, 2020 edition, Chinese herbal classic books and PhD and MSc theses, etc.). Among them with keywords including "Curcumae Rhizoma", "Ezhu", "herb pairs", "clinical application", etc. and their combinations. Moreover, the t-copula function was used to analyse the dose-coupling effect of five drug pairs, including Ezhu. RESULTS: The preliminary statistical analysis retrieved Ezhu prescriptions from self-built prescription database and internet databases. The results showed that the compatibility frequency of Ezhu with the other five Chinese medicines was high. Most of these selected herbal combinations are used to treat internal diseases. In this paper, the progress of the ethnopharmacology of Ezhu was reviewed, emphasizing the changes in bioactive components and compatibility of Chinese traditional medicine combinations such as Ezhu and Astragalus Curcuma (Sparganium stoloniferum Buch. -Ham; called Sanleng in Chinese), Ezhu and Astragali Radix (Astragalus membranaceus (Fisch.) Bge. var. mongholicus (Bge.) Hsiao, Astragalus membranaceus (Fisch.) Bge.; called Huangqi in Chinese). Some other varieties, such as Ezhu and Rhizoma Chuanxiong (Ligusticum chuanxiong Hort.; called Chuanxiong in Chinese), Trionycis Carapax (Trionyx sinensis Wiegmann; called Biejia in Chinese), and Coptidis Rhizoma (Coptis chinensis Franch., Coptis deltoidea C. Y. Cheng et Hsiao, Coptis teeta Wall.; called Huanglian in Chinese), are also recorded in ancient books but rarely researched. The dose of Ezhu is strongly correlated with the amount of Sanleng, Huangqi, Biejia, Chuanxiong and Huanglian, respectively. Furthermore, there was a positive correlation between them. CONCLUSIONS: The bioactive components and compatibility effects of Ezhu herb pairs were studied in detail using data mining and t-copula function analysis. Ezhu and Astragalus Curcuma (Sanleng) mainly treat gynecological disorders by activating blood circulation and relieving congestion. Ezhu and Astragali Radix (Huangqi) drug pair and Ezhu and Trionycis Carapax (Biejia) drug pair are all commonly used in the clinical treatment of tumors, the former is mainly used clinically for the treatment of digestive tract-related inflammation and tumors, liver cancer and gynecological tumors, and the latter is commonly used for the treatment of malignant tumors, such as liver cancer and mammary cancer.

RESUMEN

BACKGROUND/AIM: Despite recent advances in EGFR-tyrosine kinase inhibitor (TKI) drugs for glioblastoma multiforme (GBM), intrinsic EGFR alterations in GBM have resulted in drug resistance and unsatisfactory clinical development of EGFR-TKIs. Determining the unknown mechanisms underlying EGFR-TKI drug resistance is an urgent, but unmet, medical need for GBM. Although several m6A RNA methylation regulators, such as reader YTHDF1/2, were recently predicted to be related to GBM recurrence, none was associated with resistance to the 3rd generation EGFR-TKI osimertinib. MATERIALS AND METHODS: Osimertinib-resistant GBM cells (U87OSR) were established to ascertain the correlation between m6A expression and osimertinib resistance, prior to systemic analyses on m6A writers, erasers, and readers. YTHDF3-silencing was employed to reveal changes in IC50, cellular migration, cancer stemness, and p21-guided senescence in U87OSR cells. Signaling pathways and an in vivo xenograft model of U87OSR cells were investigated to delineate the influence of osimertinib-resistance and elevated YTHDF3 expression. RESULTS: YTHDF3 played a crucial role in inducing cellular proliferation, migration, and stemness in U87OSR GBM cells. Importantly, silencing of YTHDF3 markedly reduced the activation of certain signaling pathways, including EGFR- or ITGA7- AKT, and ERK in U87OSR cells. Our study also revealed the oncogenic function of YTHDF3 in inducing senescence escape via p21 down-regulation. In contrast, silencing of YTHDF3 resulted in increased p21 expression, senescence, and suppressed tumor growth in our osimertinib-resistant preclinical model. CONCLUSION: Overall, our research underscores the novel potential of YTHDF3 as a new pharmacological target in GBM treatment, specifically for patients with osimertinib-resistant or refractory tumors.

RESUMEN

Fagus pashanica is an endangered and endemic tree species in China. To understand its genetic diversity and structure for effective conservation, we used next-generation sequencing data to develop a set of microsatellite markers. Twenty-three of the 68 designed loci were successfully amplified. Fifteen polymorphic loci with clear peaks were selected for further analyses in three F. pashanica populations sampled from Nanjiang, Wangcang and Pingwu counties in Sichuan Province, China. The number of alleles per locus ranged from two to 11. The levels of observed and expected heterozygosity ranged from 0.033-0.852 and 0.033-0.787, respectively. All 23 loci were also successfully amplified in F. longipetiolata and F. lucida, and 19 were successfully amplified in F. engleriana. These microsatellite markers will be useful for population genetic studies of F. pashanica and other Fagus species.

RESUMEN

Objective: Combined physical (PHY) and cognitive (COG) training in sequential (SEQ) and simultaneous (SIMUL) sessions may delay the progression of cognitive impairment. To date, no study has directly compared in older adults with cognitive impairment the effects of COG training, PHY training, SEQ motor-cognitive training and SIMUL motor-cognitve training on specific indices of cognitive performance and activities of daily living (ADL). The purpose of this study was to determine whether SEQ and SIMUL motor-cognitive training can improve treatment outcomes compared with PHY or COG training alone. We also aimed to compare the effects of SEQ versus SIMUL motor-cognitive training on cognitive functions and instrumental ADL (IADL) in older adults with cognitive impairment. Methods: A cluster randomized controlled trial was conducted. Eighty older adults with cognitive impairment were randomly assigned to COG, PHY, SEQ or SIMUL training groups. The intervention consisted of 90-min training sessions, totaling 36 sessions. Outcome measures were the Montreal Cognitive Assessment, three subtests of the Wechsler Memory Scale (WMS) and the Lawton IADL scale. Results: Significant interaction effects between group and time were found in WMS-spatial span (p = 0.04) and WMS-word lists (p = 0.041). For WMS-spatial span, the SIMUL group showed outperformed the COG (p = 0.039), PHY (p = 0.010) and SEQ groups (p = 0.017). For WMS-word lists, the SEQ group improve more than COG (p = 0.013), PHY (p = 0.030) and SIMUL (p = 0.019) groups. No significant differences were found in IADL performance among four groups (p = 0.645). Conclusions: Our study showed SEQ and SIMUL motor-cognitive training led to more pronounced improvements in visuospatial working memory or verbal memory compared with isolated COG or PHY training for community-based older adults with cognitive impairment. For enhancing effects on IADL, we suggest the use of sensitive measurement tools and context-enriched cognitive training involving real-life task demands.

RESUMEN

Sleeve gastrectomy achieves long-term weight control by reducing gastric volume. However, postoperative gastrointestinal symptoms and insufficient nutritional intake are likely to occur, which are not conducive to physical health. A retrospective study aimed to investigate changes in nutritional status and associated factors in patients after sleeve gastrectomy. Data were collected from the medical records of patients who underwent sleeve gastrectomy at a teaching hospital in Taiwan. Data from 120 patients who met the eligibility criteria were included in the analysis. The results show that sleeve gastrectomy has a strong weight loss effect. Within 12 months, the average body mass index of the patients decreased by 13.47 kg/m2. The number of morbidly obese patients decreased from 62 (51.7%) to 3 (2.5%). However, surgery is also associated with gastrointestinal symptoms and the threat of malnutrition. The number of patients with moderate to severe nutritional risk increased from 4 (3.3%) before surgery to 24 (20%) at 12-month follow-up. Likewise, the number of patients with anemia increased from 11 (9.2%) to 29 (24.17%). Gender, constipation, and diarrhea affected postoperative nutritional status. These findings suggest that patients after sleeve gastrectomy are at risk of malnutrition and require regular monitoring. Special attention should be given to women and patients with constipation or diarrhea, as they are at a particularly high risk of malnutrition.

RESUMEN

The receptor for advanced glycation end-products (RAGE) has been implicated in tumorigenesis, whereas epidermal growth factor receptor (EGFR) signaling plays a vital role in lung cancer progression. Both RAGE and EGFR are transmembrane receptors that transmit intracellular signals through ligand binding, and their downstream signaling cascades show substantial overlap. However, the interplay between these two molecules remains poorly understood. In the present study, we evaluated the correlation between RAGE and EGFR in the tumorigenesis of non-small cell lung cancer (NSCLC) and evaluated the impact of RAGE on the response of NSCLC cells to gefitinib, an EGFR-tyrosine kinase inhibitor (TKI). The expression and activation of EGFR and the phosphorylation of its downstream molecules, signal transducer and activator of transcription 3 (STAT3) and extracellular signal-regulated kinase (Erk), were increased in RAGE-overexpressed A549 (A549-RAGE) cells. Notably, ligand-triggered activation of EGFR signaling was significantly greater in A549-RAGE compared with A549-parental cells. In addition, gefitinib had less effect on the inhibition of EGFR signaling in A549-RAGE cells. These findings were validated in other NSCLC cell lines, H1299 and H1975. Furthermore, upon gefitinib administration, the antiapoptotic marker B-cell lymphoma 2 (Bcl-2) expression was upregulated in A549-RAGE cells, whereas the apoptotic markers Bcl-2 associated X protein (Bax) and Bcl-2 interacting mediator (Bim) remained at lower levels compared with A549-parental cells. Importantly, our findings provide evidence that RAGE interferes with the anticancer effect of gefitinib by modulating the activation of EGFR-STAT3 and EGFR-Erk pathways. Overall, these significant findings deepen our understanding of the intricate relationship between RAGE and EGFR signaling in NSCLC tumorigenesis and provide new considerations for the clinical treatment of NSCLC.NEW & NOTEWORTHY This study represents a pioneering endeavor in comprehending the intricate interplay between RAGE and EGFR signaling within NSCLC. The findings reveal that RAGE serves to enhance EGFR phosphorylation and activation, consequently modulating apoptosis regulators through the EGFR-STAT3 and EGFR-Erk1/2 signaling pathways. Through this mechanism, RAGE potentially imparts resistance to the toxicity induced by EGFR-TKIs in NSCLC cells.

RESUMEN

BACKGROUND: Diabetic skin ulcers, a significant global healthcare burden, are mainly caused by the inhibition of cell proliferation and impaired angiogenesis. XB130 is an adaptor protein that regulates cell proliferation and migration. However, the role of XB130 in the development of diabetic skin ulcers remains unclear. AIM: To investigate whether XB130 can regulate the inhibition of proliferation and vascular damage induced by high glucose. Additionally, we aim to determine whether XB130 is involved in the healing process of diabetic skin ulcers, along with its molecular mechanisms. METHODS: We conducted RNA-sequencing analysis to identify the key genes involved in diabetic skin ulcers. We investigated the effects of XB130 on wound healing using histological analyses. In addition, we used reverse transcription-quantitative polymerase chain reaction, Western blot, terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling staining, immunofluorescence, wound healing, and tubule formation experiments to investigate their effects on cellular processes in human umbilical vein endothelial cells (HUVECs) stimulated with high glucose. Finally, we performed functional analysis to elucidate the molecular mechanisms underlying diabetic skin ulcers. RESULTS: RNA-sequencing analysis showed that the expression of XB130 was up-regulated in the tissues of diabetic skin ulcers. Knockdown of XB130 promoted the healing of skin wounds in mice, leading to an accelerated wound healing process and shortened wound healing time. At the cellular level, knockdown of XB130 alleviated high glucose-induced inhibition of cell proliferation and angiogenic impairment in HUVECs. Inhibition of the PI3K/Akt pathway removed the proliferative effects and endothelial protection mediated by XB130. CONCLUSION: The findings of this study indicated that the expression of XB130 is up-regulated in high glucose-stimulated diabetic skin ulcers and HUVECs. Knockdown of XB130 promotes cell proliferation and angiogenesis via the PI3K/Akt signalling pathway, which accelerates the healing of diabetic skin ulcers.

RESUMEN

BACKGROUND: Coffee is one of the most consumed beverages in the world, coffee consumption has been growing in the United States over the past 20 years. Periodontitis is defined by the pathologic loss of the periodontal ligament and destruction of the connective tissue attachment and alveolar bone loss and is related to different systemic diseases and conditions. However, the causality has remained unclarified, thus we regarded discovering the causal relationship between coffee consumption and the liability to periodontitis as the objective of the study. METHODS: Coffee consumption was subdivided into binary coffee consumption and continuous coffee consumption to refine the study design. Genetic instruments were stretched from the MRC-IEU's (MRC Integrative Epidemiology Unit) output from the GWAS pipeline using phesant-derived variables based on the UK Biobank, the Gene-Lifestyle Interactions in Dental Endpoints (GLIDE) project, and the joint meta-analysis of a recent GWAS. The IVW (Inverse Variance Weighted) was regarded as the primary method to estimate the causality, a scatter plot revealed the intuitive result, and tests for stability were also carried out. RESULTS: An effect of continuous coffee consumption on the risk of periodontitis was found, with per SD of coffee consumed increases, the risk of periodontitis rises by 1.04% (Odds Ratio of IVW is 1.0104), while the effect of binary coffee consumption on periodontitis did not meet the requirement of indicating a strong causal association, neither were the reverse causality analyses. CONCLUSIONS: The study indicated the causality of continuous coffee consumption to the risk of periodontitis with a relatively small scale of effect estimate and no strong evidence for an effect of binary coffee-consuming behavior on periodontitis. There was also no intensive evidence suggesting reverse causality.

RESUMEN

Components of the renin-angiotensin-aldosterone system (RAAS) are present on bone cells. One measure of RAAS activity, the aldosterone-renin-ratio (ARR), is used to screen for primary aldosteronism. Associations between ARR and bone mineral density are conflicting. This study investigated associations between ARR and peripheral quantitative computed tomography (pQCT) and impact microindentation (IMI). Male participants (n = 431) were from the Geelong Osteoporosis Study. "Likely" primary aldosteronism was defined as ARR ≥ 70 pmol/mIU. Another group, "possible" primary aldosteronism, was defined as either ARR ≥ 70 pmol/mIU or taking a medication that affects the RAAS, but not a beta blocker, and renin < 15 mU/L. Using pQCT, images at 4% and 66% of radial (n = 365) and tibial (n = 356) length were obtained. Using IMI measurements, bone material strength index (BMSi; n = 332) was determined. Associations between ARR or likely/possible primary aldosteronism and IMI or pQCT-derived bone parameters were tested using median regression. ARR and aldosterone values were not associated with any of the pQCT-derived bone variables in either unadjusted or adjusted analyses. Men with likely primary aldosteronism (n = 16), had lower adjusted total bone area (radial 66% site, - 12.5%). No associations were observed for men with possible primary aldosteronism (unadjusted or adjusted). No associations with BMSi were observed (p > 0.05). There were no associations between ARR or aldosterone and pQCT-derived bone parameters. Men with likely primary aldosteronism had lower bone area, suggesting clinically high levels of ARR may have a negative impact on bone health.

RESUMEN

In recent years, the demand for detection and diagnostic methods has consistently risen due to the aging of the population and the increase in the number of patients with chronic diseases. Label-free biomedical detection techniques have emerged as indispensable instruments for diagnosing a variety of diseases. The development of label-free and highly sensitive near-infrared (NIR) biomedical detection technology has attracted considerable attention. As a label-free, swift, and cost-effective analytical technique, it has demonstrated immense potential for a wide range of applications. We successfully assembled FAPbI3 near-infrared perovskite quantum dots (NIPQDs) into SiO2 shells using a rapid room-temperature atmospheric synthesis method, obtaining monodisperse FAPbI3@SiO2 nanocomposites (NCs) with a high photoluminescence quantum yield (PLQY) of 72%. Additionally, the incorporation of hydrophobic multi-branched trioctylphosphine oxide effectively passivated the surface defects of FAPbI3 NIPQDs and suppressed the hydrolysis rate of tetraethoxysilane, enabling the formation of a highly stable and high PLQY nanoscale-particle level within the FAPbI3@SiO2 core-shell structure. Notably, we successfully incorporated FAPbI3@SiO2 core-shell NCs onto InGaN blue chip as NIR excitation light sources for surface plasmon resonance sensing platforms, providing a novel platform for bioanalytical detection. With a detection sensitivity of 6302.5 nm/RIU, the system demonstrated high sensitivity, stability, and dependability. This achievement expands the biomedical research field's capacity for diagnosis, monitoring, and treatment.

RESUMEN

The role played by serum folate in the progression of nonalcoholic fatty liver disease (NAFLD) remains controversial. The purpose of this study was to investigate the association of serum folate with NAFLD and advanced liver fibrosis (AHF). We conducted a cross-sectional study with 5417 participants using 2011-2018 NHANES data. Multiple logistic regression analysis and propensity score matching analysis were used to investigate the association of serum folate with NAFLD and AHF. In the completely adjusted model, participants in the high serum folate group had a 27% (OR 0.73, 95% CI 0.62, 0.87, p = 0.0003) and 53% (OR 0.47, 95% CI 0.35, 0.63, p < 0.0001) lower odds of suffering from NAFLD and AHF, respectively, compared to the low serum folate group. The similar results in propensity score matching further validated the above association. Stratified analysis showed that the negative correlation of serum folate with NAFLD and AHF demonstrated a broad consistency across populations. The results of this study indicate that higher serum folate level was associated with lower odds of NAFLD and AHF among US adults. Further prospective studies are necessary due to the limitations of cross-sectional studies.

RESUMEN

This study aimed to assess the effectiveness of various exercise interventions in enhancing the quality of life for breast cancer survivors. To achieve this, randomized controlled trials were identified from major electronic databases, focusing on the relationship between exercise and quality of life in breast cancer survivors. The primary outcome was the impact of exercise on quality of life 12 weeks after the intervention, with a secondary outcome comparing dropout rates between intervention groups and a regular care control group. The study protocol was registered with INPLASY (INPLASY202340007). A network meta-analysis of nine randomized controlled trials involving 725 participants was conducted, examining aerobic and strength training, aerobic activity, yoga, and strength exercise. Results showed that aerobic and strength training was the most effective intervention, significantly improving the quality of life of breast cancer survivors (1.31; 95% confidence interval: 0.49 to 2.12). Aerobic activity had a borderline effect (0.83; 0.03 to 1.63), while no exercise interventions were associated with an increased dropout risk compared to the control group (regular care). The study concluded that concurrent aerobic and strength training can improve breast cancer survivors' quality of life after 12 weeks of intervention without increasing dropout risk compared to regular care.
