RESUMEN

PURPOSE: Changes in the foveal avascular zone (FAZ) metrics over time are key outcome measures for clinical trials in diabetic macular ischemia (DMI). However, artifacts and automatically delineated FAZ measurements may influence the results. We aimed to compare the artifact frequency and FAZ metrics on 3 × 3 versus 6 × 6 mm optical coherence tomography angiography (OCTA) macular scans in patients with DMI. DESIGN: Prospective, comparative image quality analysis with one-year follow-up. METHODS: Patients with diabetic retinopathy (DR) were recruited if they presented with OCTA evidence of DMI, defined as an automated FAZ (aFAZ) ≥0.5 mm2 or parafoveal capillary nonperfusion (CNP) ≥1 quadrant if the aFAZ <0.5 mm2. Only those who had both size scans were included in the analysis. The types of artifacts and FAZ delineation errors were graded before manual correction. After excluding scans with poor quality, the aFAZ, corrected FAZ (cFAZ), whole image superficial vessel density (wiSVD), and whole image deep vessel density (wiDVD) were compared on both size scans. RESULTS: Fifty-seven patients (81 eyes) with paired OCTA 3 × 3 and 6 × 6 mm scans at baseline were included in the image quality analysis. The 6 × 6 mm scan presented with more severe motion artifact (P = .02). Conversely, the 3 × 3 mm scans were more susceptible to mild decentration (P = .009). After removing all the poor-quality images, 55 eyes with both size scans entered the longitudinal analysis. The 3 × 3 mm FAZ was significantly larger than the 6 × 6 mm FAZ using either aFAZ or cFAZ (both P < .05). In contrast, the 6 × 6 mm wiSVD and wiDVD were remarkably higher than those on the 3 × 3 mm scans (both P < .001). There was a steady increase in cFAZ over one year on both size scans (both P < .01). However, the 3 × 3 mm aFAZ decreased numerically at 52 weeks (P = .02). After reviewing all the scans, poor identification of parafoveal CNP was the most common reason for erroneous aFAZ delineation. CONCLUSIONS: In DMI, the FAZ metrics are best evaluated on the 3 × 3 scan due to better resolution. However, manual correction of the FAZ margin is needed. The frequency of artifacts and aFAZ delineation errors suggest that further technical refinement is required.

RESUMEN

BACKGROUND: Early detection of fatigue is crucial for cancer patients. Although single-item scales are convenient, their diagnostic accuracy remain unclear, and the variability across studies may affect generalizability. This systematic review and meta-analysis evaluates the diagnostic value of single-item fatigue detection scales. METHODS: We systematically searched CINAHL, Cochrane Library, Embase, and PubMed. Meta-analyses were conducted to calculate pooled sensitivity, specificity, likelihood ratios, predictive values, and diagnostic odds ratios (DOR). We also calculated the area under a hierarchical summary receiver operating characteristic curve. Subgroup analyses were performed to address heterogeneity. All analyses were done R (version 4.3.1). The study registered in PROSPERO (CRDXXX). RESULTS: Eleven studies involving 3509 participants were included. Pooled results revealed a sensitivity of 0.89 (95% CI: 0.82 to 0.93), specificity of 0.72 (95% CI: 0.63 to 0.80), DOR of 19.95 (95% CI: 10.47-38.04), and an AUC of 0.90 (95% CI: 0.89-0.91). Moderate to high heterogeneity was observed, influenced by variations in cancer types, study designs, and gold standard references. CONCLUSION: Single-item fatigue scales demonstrate commendable diagnostic accuracy, comparable to multidimensional scales. Despite study variability, they are effective for routine clinical use to detect and manage fatigue in cancer patients. Future research should focus on standardizing assessment criteria and optimizing the balance between simplicity and diagnostic precision.

RESUMEN

BACKGROUND: Despite guidelines for managing chemotherapy-induced nausea and vomiting (CINV), there remains a need to clarify the optimal use of neurokinin-1 (NK1) receptor antagonists. Comparing the effectiveness of NEPA (netupitant-palonosetron) plus dexamethasone with other NK1 antagonist-based regimens combined with a 5HT3 receptor antagonist and dexamethasone is crucial for informed decision-making and improving patient outcomes. METHODS: We conducted a systematic review of the literature to assess randomized controlled trials (RCTs) comparing the efficacy, safety, and cost-effectiveness of NEPA plus dexamethasone and other NK1 antagonist-based regimens combined with a 5HT3 receptor antagonist and dexamethasone. PubMed, Embase, and the Cochrane Library databases were systematically searched, with the latest update performed in December 2023. Data on patient demographics, chemotherapy regimen characteristics, and outcomes were extracted for meta-analysis using a random-effects model. RESULTS: Seven RCTs were analyzed. NEPA plus dexamethasone showed superior efficacy in achieving complete response in the overall (risk ratio [RR], 1.15; 95% CI, 1.02--1.30) and delayed phases (RR, 1.20; 95% CI, 1.03-1.41) of chemotherapy. It was more effective in controlling nausea (overall phase RR, 1.20; 95% CI, 1.05-1.36; delayed phase RR, 1.21; 95% CI, 1.05-1.40) and reducing rescue therapy use (overall phase RR, 1.45; 95% CI, 1.07-1.95; delayed phase RR, 1.75; 95% CI, 1.10-2.78). Adverse event rates were comparable (RR, 1.03; 95% CI, 0.96-1.10). Subgroup analysis indicated NEPA's particular efficacy in patients receiving moderately emetogenic chemotherapy (RR, 1.31; 95% CI, 1.07-1.60). CONCLUSION: NEPA plus dexamethasone regimens exhibit superior efficacy in preventing CINV, supporting their preferential inclusion in prophylactic treatment protocols. Its effective symptom control, safety profile, and cost-effectiveness endorse NEPA-based regimens as a beneficial option in CINV management.

RESUMEN

Background: Acute myocardial infarction (AMI) is a critical cardiovascular disease with high morbidity and mortality. Identifying practical parameters for predicting long-term mortality is crucial in this patient group. The percentage of mean arterial pressure (%MAP) is a useful parameter used to assess peripheral artery disease. It can be easily calculated from ankle pulse volume recording. Previous studies have shown that %MAP is a useful predictor of all-cause mortality in specific populations, but its relationship with mortality in AMI patients is unclear. Methods: In this observational cohort study, 191 AMI patients were enrolled between November 2003 and September 2004. Ankle-brachial index (ABI) and %MAP were measured using an ABI-form device. All-cause and cardiovascular mortality data were collected from a national registry until December 2018. Cox proportional hazards model and Kaplan-Meier survival plot were used to analyze the association between %MAP and long-term mortality in AMI patients. Results: The median follow-up to mortality was 65 months. There were 130 overall and 36 cardiovascular deaths. High %MAP was associated with increased overall mortality after multivariable analysis (HR = 1.062; 95% CI: 1.017-1.109; p =0.006). However, high % MAP was only associated with cardiovascular mortality in the univariable analysis but became insignificant after the multivariable analysis. Conclusions: In conclusion, this study is the first to evaluate the usefulness of %MAP in predicting long-term mortality in AMI patients. Our study shows that %MAP might be an independent predictor of long-term overall mortality in AMI patients and has better predictive power than ABI.

RESUMEN

BACKGROUND: Glioblastoma multiforme (GBM) is an aggressive type of brain tumor that is difficult to remove surgically. Research suggests that substances from saffron, namely crocetin and crocin, could be effective natural treatments, showing abilities to kill cancer cells. METHODS: Our study focused on evaluating the effects of crocetin on glioma using the U87 cell line. We specifically investigated how crocetin affects the survival, growth, and spread of glioma cells, exploring its impact at concentrations ranging from 75-150 µM. The study also included experiments combining crocetin with the chemotherapy drug Temozolomide (TMZ) to assess potential synergistic effects. RESULTS: Crocetin significantly reduced the viability, proliferation, and migration of glioma cells. It achieved these effects by decreasing the levels of Matrix Metallopeptidase 9 (MMP-9) and Ras homolog family member A (RhoA), proteins that are critical for cancer progression. Additionally, crocetin inhibited the formation of cellular structures necessary for tumor growth. It blocked multiple points of the Ak Strain Transforming (AKT) signaling pathway, which is vital for cancer cell survival. This treatment led to increased cell death and disrupted the cell cycle in the glioma cells. When used in combination with TMZ, crocetin not only enhanced the reduction of cancer cell growth but also promoted cell death and reduced cell replication. This combination therapy further decreased levels of high mobility group box 1 (HMGB1) and Receptor for Advanced Glycation End-products (RAGE), proteins linked to inflammation and tumor progression. It selectively inhibited certain pathways involved in the cellular stress response without affecting others. CONCLUSION: Our results underscore the potential of crocetin as a treatment for glioma. It targets various mechanisms involved in tumor growth and spread, offering multiple avenues for therapy. Further studies are essential to fully understand and utilize crocetin's benefits in treating glioma.

RESUMEN

In recent years, with the rapid development of blockchain technology, the issues of storage load and data security have attracted increasing attention. Due to the immutable nature of data on the blockchain, where data can only be added and not deleted, there is a significant increase in storage pressure on blockchain nodes. In order to alleviate this burden, this paper proposes a blockchain data storage strategy based on a hot and cold block mechanism. It employs a block heat evaluation algorithm to assess the historical and correlation-based heat indicators of blocks, enabling the identification of frequently accessed block data for storage within the blockchain nodes. Conversely, less frequently accessed or "cold" block data are offloaded to cloud storage systems. This approach effectively reduces the overall storage pressure on blockchain nodes. Furthermore, in applications such as healthcare and government services that utilize blockchain technology, it is essential to encrypt stored data to safeguard personal privacy and enforce access control measures. To address this need, we introduce a blockchain data encryption storage mechanism based on threshold secret sharing. Leveraging threshold secret sharing technology, the encryption key for blockchain data is fragmented into multiple segments and distributed across network nodes. These encrypted key segments are further secured through additional encryption using public keys before being stored. This method serves to significantly increase attackers' costs associated with accessing blockchain data. Additionally, our proposed encryption scheme ensures that each block has an associated encryption key that is stored alongside its corresponding block data. This design effectively mitigates vulnerabilities such as weak password attacks. Experimental results demonstrate that our approach achieves efficient encrypted storage of data while concurrently reducing the storage pressure experienced by blockchain nodes.

RESUMEN

Sodium-glucose cotransporter-2 inhibitors (SGLT2i) have a variety of cardiovascular and renoprotective effects and have been developed as novel agents for the treatment of heart failure. However, the beneficial mechanisms of SGLT2i on cardiac tissue need to be investigated further. In this study, we established a mouse model of acute myocardial infarction (AMI) using coronary artery constriction surgery and investigated the role of dapagliflozin (DAPA) in protecting cardiomyocytes from hypoxic injury induced by AMI. In vitro experiments were done using hypoxic cultured H9c2 ventricular cells to verify this potential mechanism. Expression of the SIRT family and related genes and proteins was verified by qPCR, Western blotting and immunofluorescence staining, and the intrinsic potential mechanism of cardiomyocyte death due to AMI and hypoxia was comprehensively investigated by RNA sequencing. The RNA sequencing results of cardiomyocytes from AMI mice showed that the SIRT family may be mainly involved in the mechanisms of hypoxia-induced cardiomyocyte death. In vitro hypoxia-induced ventricular cells showed the role of dapagliflozin in conferring resistance to hypoxic injury in cardiomyocytes. It showed that SIRT1/3/6 were downregulated in H9c2 cells in a hypoxic environment, and the addition of dapagliflozin significantly increased the gene and protein expression of SIRT1, 3 and 6. We then verified the underlying mechanisms induced by dapagliflozin in hypoxic cardiomyocytes using RNA-seq, and found that dapagliflozin upregulated the hypoxia-induced gene downregulation, which includes ESRRA, EPAS1, AGTRAP, etc., that associated with SIRTs-related and apoptosis-related signaling to prevent H9c2 cell death. This study provides laboratory data for SGLT2i dapagliflozin treatment of AMI and confirms that dapagliflozin can be used to treat hypoxia-induced cellular necrosis in cardiomyocytes, in which SIRT1 and SIRT3 may play an important role. This opens up further opportunities for SGLT2i in the treatment of heart disease.

RESUMEN

3D bioprinting, a significant advancement in biofabrication, is renowned for its precision in creating tissue constructs. Collagen, despite being a gold standard biomaterial, faces challenges in bioink formulations due to its unique physicochemical properties. This study introduces a novel, neutral-soluble, photocrosslinkable collagen maleate (ColME) that is ideal for 3D bioprinting. ColME was synthesized by chemically modifying bovine type I collagen with maleic anhydride, achieving a high substitution ratio that shifted the isoelectric point to enhance solubility in physiological pH environments. This modification was confirmed to preserve the collagen's triple-helix structure substantially. Bioprinting parameters for ColME were optimized, focusing on adjustments to the bioink concentration, extrusion pressure, nozzle speed, and temperature. Results demonstrated that lower temperatures and smaller nozzle sizes substantially improved the print quality of grid structures. Additionally, the application of intermittent photo-crosslinking facilitated the development of structurally robust 3D multilayered constructs, enabling the stable fabrication of complex tissues. Cell viability assays showed that encapsulated cells within the ColME matrix maintained high viability after printing. When compared to methacrylated gelatin, ColME exhibited superior mechanical strength, resistance to enzymatic digestion, and overall printability, positioning it as an outstanding bioink for the creation of durable, bioactive 3D tissues.

RESUMEN

BACKGROUND: Chronic hepatitis C (CHC) increases the risk of liver cirrhosis (LC) and hepatocellular carcinoma (HCC). This nationwide cohort study assessed the effectiveness of viral eradication of CHC. METHODS: The Taiwanese chronic hepatitis C cohort and Taiwan hepatitis C virus (HCV) registry are nationwide HCV registry cohorts incorporating data from 23 and 53 hospitals in Taiwan, respectively. This study included 27,577 individuals from these cohorts that were given a diagnosis of CHC and with data linked to the Taiwan National Health Insurance Research Database. Patients received either pegylated interferon and ribavirin or direct-acting antiviral agent therapy for > 4 weeks for new-onset LC and liver-related events. RESULTS: Among the 27,577 analyzed patients, 25,461 (92.3%) achieved sustained virologic response (SVR). The mean follow-up duration was 51.2 ± 48.4 months, totaling 118,567 person-years. In the multivariable Cox proportional hazard analysis, the hazard ratio (HR) for incident HCC was 1.39 (95% confidence interval [CI]: 1.00-1.95, p = 0.052) among noncirrhotic patients without SVR compared with those with SVR and 1.82 (95% CI 1.34-2.48) among cirrhotic patients without SVR. The HR for liver-related events, including HCC and decompensated LC, was 1.70 (95% CI 1.30-2.24) among cirrhotic patients without SVR. Patients with SVR had a lower 10-year cumulative incidence of new-onset HCC than those without SVR did (21.7 vs. 38.7% in patients with LC, p < 0.001; 6.0 vs. 18.4% in patients without LC, p < 0.001). CONCLUSION: HCV eradication reduced the incidence of HCC in patients with and without LC and reduced the incidence of liver-related events in patients with LC.

RESUMEN

BACKGROUND: Insufficient data available for older patients with breast cancer complicates decision-making regarding optimal treatment. A systematic review that uses real-world data is required for assessing the effectiveness and potential adverse effects of various therapies for this age group of patients. METHODS: Databases of PubMed, Embase, and Cochrane Library were searched. We included clinical studies that evaluated various treatments for geriatric breast cancer, including adjuvant radiation therapy, hypofractionated radiation therapy (hypo-RT) and accelerated and partial breast irradiation (APBI), endocrine therapy, chemotherapy, and targeted therapy. RESULTS: A total of 71 studies were retrieved. Adjuvant radiation therapy significantly improved overall survival (OS) compared with no radiation [hazard ratio (HR) = 0.60, 95% confidence interval (CI) 0.54-0.67]. The pooled estimates of OS for hypo-RT and APBI demonstrated no inferiority compared with conventional radiation. Both endocrine treatment (HR = 0.63, 95% CI 0.43-0.92) and chemotherapy (HR = 0.76, 95% CI 0.65-0.88) significantly increased OS compared with no treatment. Trastuzumab monotherapy significantly enhanced OS compared with no trastuzumab use (HR = 0.23, 95% CI 0.07-0.73). CONCLUSION: Despite concerns about potential complications during treatment in older patients, proactive therapies significantly increase their survival rates. For patients who are frailer, hypo-RT and APBI offer survival rates comparable to traditional modalities. Additionally, targeted therapy as a monotherapy holds promise as a viable option for patients with HER2-positive breast cancer who cannot undergo chemotherapy. Therefore, by conducting thorough general assessments and clinical evaluations, the side effects of postoperative treatments can be effectively managed.

RESUMEN

BACKGROUND: The efficacy of different nucleos(t)ide analogs in the treatment of chronic hepatitis B virus (CHB) with severe acute exacerbation (SAE) remained unclear. Thus, this study aimed to compare the short-term efficacy of tenofovir disoproxil fumarate (TDF) and entecavir (ETV) in patients having CHB with SAE. METHODS: We analyzed consecutive patients with treatment-naive CHB receiving TDF (n = 36) or ETV (n = 65) for SAE. The primary endpoint was overall mortality or receipt of liver transplantation (LT) by 24 weeks. The secondary endpoints are the comparison of ETV vs. TDF influences on renal function and virological and biochemical responses at 4, 12, 24, and 48 weeks. RESULTS: The baseline characteristics were comparable between the two groups. By 24 weeks, 8 (22%) patients in the TDF group and 10 (15%) patients in the ETV group had either died (n = 15) or received LT (n = 3) ( P  = 0.367). Cox-regression multivariate analysis revealed age ( P  = 0.003), baseline international normalized ratio of prothrombin time ( P  = 0.024), and early presence of hepatic encephalopathy ( P  = 0.003) as independent factors associated with mortality or LT. The two groups of patients achieved comparable biochemical and virological responses at 48 weeks. No significant difference was found in the estimated glomerular filtration rate (eGFR) between the TDF and the ETV groups. However, a significant reduction in the eGFR at 48 weeks, as compared with the baseline, was found in each group. CONCLUSION: TDF and ETV achieved similar short-term clinical outcomes and treatment responses in CHB patients with SAE.

RESUMEN

PURPOSE: The study investigates cryotherapy's efficacy in mitigating Chemotherapy-induced peripheral neuropathy (CIPN), an adverse effect of chemotherapy that often leads to dosage reduction or treatment discontinuation. METHOD: The study was registered with PROSPERO (CRD42023428936). A literature search was conducted using the PubMed, Embase, and Cochrane Library databases. Randomized and nonrandomized controlled trials that investigated the effects of cryotherapy on CIPN were included for systematic review and meta-analysis. The primary outcome for prevention was the incidence of CIPN. RESULTS: We identified 17 trials involving 2,851 patients. In total, 11 trials compared the incidence of CIPN between cryotherapy and control groups. Significant differences in the incidence of CIPN at the midpoint and end of chemotherapy were observed, with risk ratios (RRs) of 0.23 (95% confidence interval [CI] = 0.13 to 0.43) and 0.54 (95% CI = 0.33 to 0.88), respectively. Cryotherapy also significantly reduced the incidence of sensory CIPN, with an RR of 0.67 (95% CI = 0.49 to 0.92). Additionally, cryotherapy demonstrated a significant reduction in the incidence of CIPN in patients with gynecological cancers (RR = 0.24, 95% CI = 0.14 to 0.41). Significantly favorable global quality of life scores following chemotherapy (standardized mean difference = 1.43; 95% CI = 0.50 to 2.36) and relieved neuropathic symptoms were found with cryotherapy. CONCLUSIONS: Cryotherapy demonstrates a pronounced preventive effect against the development of CIPN, providing substantial symptomatic relief and quality of life improvements for patients undergoing chemotherapy. The administration of cryotherapy through the use of frozen gloves and socks, or continuous-flow cooling systems, optimally initiated 15 min prior to and concluded 15 min following chemotherapy, is recommended for achieving maximum therapeutic efficacy.

RESUMEN

Recent studies have identified a correlation between chronic viral hepatitis and cognitive impairment, yet the underlying mechanisms remain unclear. This study investigated the influence of TGFB1 genetic polymorphisms on cognitive function in individuals with and without hepatitis infections, hypothesizing that these polymorphisms and the viral hepatitis-induced inflammatory environment interact to affect cognitive abilities. Participants (173 with viral hepatitis and 258 healthy controls) were recruited. Genotyping of TGFB1 SNPs was performed using the C2-58 Axiom Genome-Wide TWB 2.0 Array Plate. Cognitive function was assessed using the MMSE and MoCA tests. Our results showed that healthy individuals carrying the C allele of rs2241715 displayed better performance in sentence writing (p = 0.020) and language tasks (p = 0.022). Notably, viral hepatitis was found to moderate the impact of the rs2241715 genotype on language function (p = 0.002). Similarly, those carrying the T allele of rs10417924 demonstrated superior orientation to time (p = 0.002), with viral hepatitis modifying the influence of the SNP on this particular cognitive function (p = 0.010). Our findings underscore the significant role of TGFß1 in cognitive function and the moderating impact of viral hepatitis on TGFB1 SNP effects. These findings illuminate the potential of TGFB1 as a therapeutic target for cognitive impairment induced by viral hepatitis, thus broadening our understanding of TGFß1 functionality in the pathogenesis of neurodegeneration.

RESUMEN

BACKGROUND: Hepatocellular carcinoma (HCC) remains a major cause of cancer-related mortality worldwide, with treatment options including radiofrequency ablation (RFA) and surgical resection. This study evaluates the evolving guidelines for these treatments to identify the current consensus and divergences. METHOD: We conducted a systematic review following PRISMA 2020 guidelines of documents from 2017-2024 by major liver societies. The AGREE-II framework assessed guideline quality. This study is registered with PROSPERO (CRDXXXX). RESULTS: We analyzed 23 guidelines and noted significant shifts in treatment recommendations over recent updates. This analysis reveals an increasing endorsement of RFA for certain patient groups and sustained strong support for surgical resection based on robust evidence levels. All demonstrated high quality, with the 2023 Japan Guidelines receiving the highest AGREE-II score. A significant finding was the low level of stakeholder involvement in the development of guidelines. CONCLUSION: The study highlights the dynamic nature of clinical guidelines for early-stage HCC, underscoring the need for ongoing updates and direct, high-quality comparative studies. The evolving recommendations for RFA, especially its role in managing small, localized tumors, reflect its emerging importance in the treatment paradigm.

RESUMEN

In this study, we investigated the prevalence of mental health problems among patients with cancer and whether oncology nurse navigation improved their mental health outcomes and medical experience. In this randomized controlled clinical trial, we recruited 128 outpatients with cancer via purposive sampling from a teaching hospital in northern Taiwan. Participants were randomly assigned to the navigation group (N = 61) or the usual care group (N = 67). Data were collected from January 2019 to July 2020 using questionnaires, including the self-reported Distress Thermometer, Hospital Anxiety and Depression Scale, Demoralization Scale, and Patient Assessment of Chronic Illness Care. Data were collected at baseline and after three and six months of the intervention. Descriptive and analytical statistical analyses were performed. The prevalence rates of anxiety, depression, distress, and demoralization were 17.9%, 15.7%, 29.7%, and 29.7%, respectively. After three months, the participants in the navigation group exhibited significantly reduced levels of anxiety, demoralization, and emotional distress (reduced by 92%, 75%, and 58%, respectively) and reported a better medical experience (odds ratio = 1.40) than those in the usual care group.

RESUMEN

Rheumatoid arthritis (RA) requires therapeutic approaches that alleviate symptoms and inhibit the progression of joint damage. Glucocorticoids (GCs) have been a cornerstone of RA treatment, yet their use is often limited by side effects. Recent advancements suggest that liposome-based delivery systems can improve GC biodistribution, minimizing toxicity. This study introduces an innovative tool for RA treatment using prednisone-encapsulated nonphospholipid liposomes (NPLs) in combination with a hyaluronic acid (HA) hydrogel. Our methodology involved incorporating prednisone (PR) with palmitic acid and cholesterol to formulate stable NPLs using a thin-film hydration technique. The synthesized PR-NPLs, characterized by a mean size of 150 nm, demonstrated uniform distribution and higher drug encapsulation in comparison with conventional phospholipid liposomes. In vitro assays revealed that PR-NPL markedly reduced inflammatory responses in macrophages. Additionally, we successfully incorporated PR-NPL into an HA hydrogel, employing a photoinitiated cross-linking process. This novel composite offered modulable PR release, governed by the degree of hydrogel cross-linking. The developed system presents a promising advancement in RA management, especially suited for intraarticular injections. It potentially enables targeted, controlled drug release with a reduced risk of side effects, signifying a significant improvement over existing RA therapies.

RESUMEN

BACKGROUND: Liver resection (LR) and radiofrequency ablation (RFA) are the most commonly used treatment modalities for early-stage hepatocellular carcinoma (ES-HCC). The comparative efficacy of LR and RFA in ES-HCC remains debated. We conducted a meta-analysis based on randomized trials to compare the outcomes of LR and RFA. METHODS: We searched PubMed, Embase, the Cochrane Library, and ClinicalTrials.gov for randomized controlled trials (RCTs) comparing RFA and LR interventions for the treatment of ES-HCC. The primary outcomes were overall survival (OS) and disease-free survival (DFS). We used meta-regression to determine the source of heterogeneity and conducted a trial sequential analysis to examine whether the outcome was statistically reliable. RESULTS: Our meta-analysis included nine RCTs with a total of 1,516 HCC patients. Compared with patients receiving RFA, those receiving LR did not have significantly different 2-year OS (HR=1.28, 95% CI: 0.73-2.23) and 5-year OS (HR=1.49, 95% CI: 0.99-2.24). However, patients receiving LR showed a favorable trend in 2-year DFS (HR=1.40, 95% CI: 1.16-1.69) and 5-year DFS (HR=1.37; 95% CI: 1.05-1.77), although these results are not conclusive due to underpowered significance. The heterogeneity was low, and the outcomes were statistically reliable. DISCUSSION: Meta-analysis suggests that while LR shows a favorable trend in DFS compared to RFA for ES-HCC, the present evidence does not thoroughly support recommending LR over RFA. The inconclusive nature of these findings highlights the need for further large-scale RCTs to establish definitive comparative efficacy.

RESUMEN

Multiple myeloma (MM) was one of the hardest cancers to diagnose because of numerous nonspecific symptoms, leading to diagnostic delay. Proactive consultation of laboratory medicine (PCLM) could help timely diagnosis of blood cancers, avoiding diagnostic delay. This study aimed to evaluate the effect of PCLM on diagnosis and outcomes in MM. This retrospective study was conducted in newly diagnosed MM patients from 2011 to 2022. Implementation of PCLM initiated in 2015 with a laboratory-oriented algorithm. The annual diagnostic rate, patient demographics, the time intervals from symptom onset to diagnosis and to treatment, and clinical outcomes were analyzed. A total of 134 patients were newly diagnosed during the study interval. The diagnostic rate increased from 4.65 ±â€…1.59 to 7.43 ±â€…1.52 per million patient-visits after implementation of PCLM. The median time interval from symptom onset to diagnosis was significantly shortened after implementation of PCLM (50 days with interquartile range [IQR]: 24-136 days vs 150 days with IQR: 41-385 days, P = .003). Besides, the 1-year survival was significantly higher in patients diagnosed as MM after implementation of PCLM (72.4% vs 51.7%, P = .035). Implementation of PCLM not only increased diagnostic rate of MM and improved outcomes, but also raise awareness for MM and promote multidisciplinary collaboration in healthcare.

RESUMEN

Background: Due to its prevalence, recurrence, and the emergence of drug-resistance, Candida vaginitis significantly impacts the well-being of women. Although cinnamon essential oil (CEO) possesses antifungal activity, its hydrophobic properties limit its clinical application. Purpose: To overcome this challenge, a nanoemulsification technology was employed to prepare cinnamon essential oil-nanoemulsion (CEO@NE), and its therapeutic efficacy and action mechanism for Candida vaginitis was investigated in vivo and in vitro. Materials and Methods: CEO@NE, composed of 4% CEO, 78% distilled water, and 18% Tween 80, was prepared by ultrasonic nanoemulsification. The physical properties, anti-Candida activity, cytotoxicity, immunomodulatory potential and storage stability of CEO@NE were explored. Subsequently, the effect of intravaginal CEO@NE treatment on Candida vaginitis was investigated in mice. To comprehend the possible mechanism of CEO@NE, an analysis was conducted to ascertain the production of intracellular reactive oxygen species (ROS) in C. albicans. Results: CEO@NE, with the droplet size less than 100 nm and robust storage stability for up to 8 weeks, exhibited comparable anti-Candida activity with CEO. CEO@NE at the concentration lower than 400 µg/mL had no cytotoxic and immunomodulatory effects on murine splenocytes. Intravaginal treatment of CEO@NE (400 µg/mL, 20 µL/day/mouse for 5 consecutive days) curbed Candida colonization, ameliorated histopathological changes, and suppressed inflammatory cytokine production in mice intravaginally challenged with C. albicans. Notably, this treatment preserved the density of vaginal lactic acid bacteria (LAB) crucial for vaginal health. Co-culturing C. albicans with CEO@NE revealed concentration-dependent augmentation of intracellular ROS generation and ensuing cell death. In addition, co-culturing LPS-stimulated murine splenocytes with CEO@NE yielded a decrease in the generation of cytokines. Conclusion: This discovery provides insight into the conceivable antifungal and anti-inflammatory mechanisms of CEO@NE to tackle Candida vaginitis. CEO@NE offers a promising avenue to address the limitations of current treatments, providing novel strategy for treating Candida vaginitis.

RESUMEN

COVID-19, a viral infection that emerged in late 2019, induces a severe acute respiratory syndrome marked by significant clinical symptoms, and the potential for progressive respiratory failure and death. People facing the threat of COVID-19 not only feared being infected, but were also worried about the side-effects of vaccination. This conflict affected their epidemic prevention behavior. To understand this issue, the present study explored whether infection anxiety affected the psychological avoidance or approach to getting vaccinated and the intention to take epidemic prevention measures. The study implemented a cross-sectional, web-based survey. We created questionnaires using Surveycake, an online e-form questionnaire platform. We used the snowball sampling method via a social media app to recruit participants. If individuals were willing to participate in the research, we emailed the e-form questionnaire link to them to collect data. After questionnaire collection, 288 questionnaires were returned, and 277 valid questionnaires were obtained for structural equation modeling analysis. According to the statistical results, it was found that infection anxiety was positively related to avoidance-avoidance conflict, and the power of infection anxiety on avoidance conflict was 23.0%. Infection anxiety was negatively related to approach-approach conflict regarding vaccination, and the power of infection anxiety on approach-approach conflict was 22.0%. Approach-approach conflict regarding vaccination was negatively related to prevention behavior, while avoidance-avoidance conflict regarding vaccination was positively related to prevention behavior. The two conflicts explained 12.5% of the total variance in prevention behavior. The study results highlight the long-term importance of achieving vaccine goals in order to prepare for future health emergencies similar to the recent COVID-19 pandemic.
