RESUMO
BACKGROUND: To investigate the prognostic value and potential therapeutic target of the baseline serum hormones in patients with metastatic castration-resistant prostate cancer (mCRPC) treated with abiraterone. METHODS: This retrospective study was performed in patients with mCRPC receiving abiraterone acetate (AA) from July 2016 to September 2020. Patients who had serum hormone tests within 2 weeks before AA treatment were included. Univariate analysis and Cox regression were performed to evaluate the correlation of sex hormones with progression-free survival (PFS) and overall survival (OS). Prolactin (PRL) expression in the clinical specimens was evaluated by immunohistochemistry. Bone metastases were quantified by automated Bone Scan Index (aBSI). RESULTS: The study included 61 patients with a median follow-up of 19.0 months. Patients with lower baseline PRL levels (median) responded better to AA than those with higher baseline PRL levels as indicated by prostate-specific antigen (PSA) reduction (PSA90, 66.7% vs. 25.8%, p = 0.001), PFS (19.6 vs. 7.9 months), and OS (52.8 vs. 19.2 months). Cox regression adjusted for clinical factors also confirmed that baseline PRL level was an independent predictive factor for PFS (hazard ratio = 1.096, p = 0.007). Prostatic PRL expression increased as the disease progressed. PRL expression was also detected in biopsy samples from bone metastasis but not in normal bone tissue, and the serum PRL levels were positively correlated with aBSIs (r = 0.28, p = 0.037). CONCLUSIONS: Serum PRL levels are predictive of response to AA in patients with mCRPC. Serum PRL levels are positively correlated with the volume of metastatic bone disease.

AIM: Transarterial chemoembolization (TACE) combined with a PD-1 inhibitor and TACE combined with a PD-1 inhibitor and lenvatinib have recently been reported as promising treatments to improve the prognosis of hepatocellular carcinoma (HCC) patients. This study aims to compare the efficacy of these two treatments. METHODS: A retrospective study was conducted, and patients were recruited from two centers in China. Progression-free survival (PFS) and overall survival (OS) were compared, and the objective response rate (ORR) and disease control rate (DCR) were evaluated according to the modified Response Evaluation Criteria in Solid Tumors (mRECIST). Treatment-related adverse events (AEs) were analyzed to assess safety. RESULTS: The median follow-up for the entire cohort was 11.4 months. Of the 103 patients included in this study, 56 received triple therapy, and 47 received doublet therapy. PFS was significantly higher in the triple therapy group than in the doublet therapy group (mPFS 22.5 vs. 14.0 months, P < 0.001). Similar results were obtained in terms of OS (P = 0.001). The ORR and DCR were also better in the triple therapy group (64.3% vs. 38.3%, P = 0.010; 85.7% vs. 57.4%, P = 0.002). The most common AEs in the triple therapy group were decreased albumin (55.3%), decreased platelet count (51.8%) and hypertension (44.6%). CONCLUSIONS: The combination of TACE with a PD-1 inhibitor and lenvatinib in patients with BCLC stage B HCC might result in significantly improved clinical outcomes with a manageable safety profile compared with TACE with a PD-1 inhibitor.
RESUMO
BACKGROUND: In the United States, sepsis accounts for 13% of the total hospital expenses and > 50% of hospital deaths. Moreover, people with sepsis are more likely to be readmitted. OBJECTIVE: The aim of this study was to assess the prevalence and outcomes of different hospital readmissions (DHRs) in patients with sepsis, and the factors associated with DHR. METHODS: We used data from the Nationwide Readmissions Database of the United States in 2017 to identify patients admitted for sepsis. Multivariable logistic regression analysis was used to evaluate the factors associated with DHR; five models were constructed to elucidate the relationship between DHR and in-hospital outcomes. RESULTS: In 2017, 85,120 (21.97%) of all patients with sepsis readmitted within 30 days in the United States were readmitted to a different hospital. The most common reason for readmission was infection irrespective of hospital status. Compared with the patients with sepsis who were readmitted to the same hospital, DHR was associated with higher hospitalization costs ($2264; 95% CI $1755-$2772; p < 0.001), longer length of stay (0.58 days; 95% CI 0.44-0.71 days; p < 0.001), and higher risk of in-hospital mortality (odds ratio 1.63; 95% CI 1.55-1.72; p < 0.001). CONCLUSIONS: DHR occurred in one-fifth of patients with sepsis in the United States. Our findings suggest that patients readmitted to a different hospital within 30 days may experience higher in-hospital mortality, longer length of stay, and higher hospitalization costs. Future studies need to examine whether continuity of care can improve the prognosis of patients with sepsis.

BACKGROUND: Patients with hepatocellular carcinoma (HCC) bile duct tumor thrombus (BDTT) have a high rate of postoperative recurrence. We aimed to describe the patterns and kinetics of recurrence in BDTT patients and provide management options accordingly. METHODS: This retrospective study included 311 HCC patients with BDTT who underwent surgery from 2009 to 2017 at five centers in China. The hazard rate of recurrence was calculated using the hazard function. RESULTS: The hazard rate of intrahepatic recurrence was higher than that of extrahepatic recurrence (0.0588 vs. 0.0301), and both showed a decreasing trend, and the intrahepatic recurrence and extrahepatic recurrence risk decreased to a lower level after 40 and 20 months, respectively. Patients who underwent anatomic resection had a consistently lower hazard rate of recurrence than patients who underwent nonanatomic resection, whereas patients who received postoperative adjuvant transarterial chemoembolization (TACE) mainly had a lower hazard rate of recurrence in the first year than patients who did not. CONCLUSION: The follow-up of BDTT patients should be at least 40 months because of its high rate of recurrence, in parallel with the need for vigilance for extrahepatic recurrence within 20 months. Anatomic hepatectomy and adjuvant TACE are recommended to improve BDTT patient outcomes.

BACKGROUND AND AIMS: The relationship between serum cholesterol level and development of hepatocellular carcinoma (HCC) remains unclear. We investigated the effects of serum cholesterol level on development of liver tumors in mice. METHODS: We performed studies with C57BL/6J mice, mice with disruption of the low-density lipoprotein receptor gene (Ldlr-/-mice), and mice with conditional deletion of nature killer (NK) cells (NKdele mice). Some C57BL/6J and NKdele mice were given injections of diethylinitrosamine to induce liver tumor formation. Mice were placed on a normal diet (ND) or high-cholesterol diet (HCD) to induce high serum levels of cholesterol. We also studied mice with homozygous disruption of ApoE (ApoE-/- mice), which spontaneously develop high serum cholesterol. C57BL/6J and NKdele mice on the ND or HCD were implanted with Hep1-6 (mouse hepatoma) cells and growth of xenograft tumors and lung metastases were monitored. Blood samples were collected from mice and analyzed by biochemistry and flow cytometry; liver and tumor tissues were collected and analyzed by histology, immunohistochemistry, and RNA-sequencing analysis. NK cells were isolated from mice and analyzed for cholesterol content, lipid raft formation, immune signaling, and changes in functions. We obtained matched tumor tissues and blood samples from 30 patients with HCC and blood samples from 40 healthy volunteers; levels of cholesterol and cytotoxicity of NK cells were measured. RESULTS: C57BL/6J mice on HCD and ApoE-/- mice with high serum levels of cholesterol developed fewer and smaller liver tumors and lung metastases after diethylinitrosamine injection or implantation of Hep1-6 cells than mice on ND. Liver tumors from HCD-fed mice and ApoE-/- mice had increased numbers of NK cells compared to tumors from ND-fed mice. NKdele mice or mice with antibody-based depletion for NK cells showed similar tumor number and size in ND and HCD groups after diethylinitrosamine injection or implantation of Hep1-6 cells. NK cells isolated from C57BL/6J mice fed with HCD had increased expression of NK cell-activating receptors (natural cytotoxicity triggering receptor 1 and natural killer group 2, member D), markers of effector function (granzyme B and perforin), and cytokines and chemokines compared with NK cells from mice on ND; these NK cells also had enhanced cytotoxic activity against mouse hepatoma cells, accumulated cholesterol, increased lipid raft formation, and immune signaling activation. NK cells isolated from HCD-fed Ldlr-/- mice did not have increased cholesterol content or cytotoxic activity against mouse hepatoma cells compared with ND-fed Ldlr-/- mice. Serum levels of cholesterol correlated with number and activity of NK cells isolated from human HCCs. CONCLUSIONS: Mice with increased serum levels of cholesterol due to an HCD or genetic disruption of ApoE develop fewer and smaller tumors after injection of hepatoma cells or a chemical carcinogen. We found cholesterol to accumulate in NK cells and activate their effector functions against hepatoma cells. Strategies to increase cholesterol uptake by NK cells can be developed for treatment of HCC.

Immune checkpoint inhibitors (ICIs) have shown remarkable clinical effects in many cancer types. However, ICIs could also induce severe organ system toxicities, including those of the hematological system. The present study aimed to extensively characterize the hematological toxicities of ICIs immunotherapy. Data were extracted from the US Food and Drug Administration Adverse Event Reporting System (FAERS) database from January 1, 2014, to March 31, 2019. Disproportionality analysis, including information component (IC) and reporting odds ratio (ROR), was used to detect potential disproportionality signal. The lower boundary of the 95% confidence interval of IC (IC025 ) exceeding zero or that of ROR (ROR025 ) exceeding one was considered statistically significant for detecting disproportionality signal. A total of 29 294 335 records were extracted from the database, with 132 573 related to ICIs. Overall, hematological adverse events (AEs) were more frequently reported in ICIs (IC025 : 0.81; ROR025 : 1.80). On further analysis, hematological AEs were overreported in female patients (female vs male, ROR025 : 1.04) and anti-CTLA-4 monotherapy groups (anti-CTLA-4 vs anti-PD-1, ROR025 : 1.33) and polytherapy groups (polytherapy vs monotherapy, ROR: 1.20, ROR025 : 1.11). Moreover, class-specific hematological AEs were also detected and differed in unique ICI regimens. Notably, disseminated intravascular coagulation had the highest proportion of death outcomes among the top 10 most frequently reported ICI-associated hematological AEs. Our study shows a high reporting frequency of hematological AEs induced by ICI monotherapy (especially by anti-CTLA-4 therapy) and reinforced by polytherapy. A spectrum of class-specific disproportionality signal was also detected; some were fatal and reported for the first time. The heterogeneous clinical spectrum of hematological toxicities, including the non-negligible proportion of death as reported outcome, are warranted to be reminded by clinicians. Early recognition and management of ICI-related hematological AEs are highly important and further studies are needed to confirm the results of our study.

BACKGROUND & AIMS: End-stage liver disease (ESLD) happens due to the development and progression of chronic liver disease. This study aims to investigate the temporal trend, patient characteristics and outcomes of atrial fibrillation (AF) in hospitalized ESLD patients across the United States. METHODS: Nationwide Inpatient Sample from 2003 to 2014 was utilized to retrospectively study the weighted prevalence of AF in hospitalized ESLD patients. Multivariable regression models were used to assess the association between AF with clinical factors, in-hospital mortality, length of stay (LOS) and cost. RESULTS: 639 345 hospitalizations associated with ESLD were identified, of which 47 710 (7.48%) were diagnosed with AF. The prevalence of AF increased from 5.73% in 2003 to 9.75% in 2014 in ESLD and varied by age, race, income, insurance type and hospital characteristics. Factors associated with AF included advancing age, male, white race, high income and urban teaching hospital. AF presence was associated with significant higher in-hospital mortality (odds ratio, 1.40; 95% confidence interval, 1.35-1.45), 21% longer LOS and 22% higher cost. In addition, a significant decreasing trend in in-hospital mortality was observed (from 16.70% to 10.63% in patients with AF and from 10.74% to 7.50% in patients without AF). CONCLUSIONS: The prevalence of AF in hospitalized ESLD patients has continued to increase from 2003 through 2014. AF is associated with poor prognosis and higher health resource utilization. Innovative anticoagulation strategies through improved collaboration between cardiologists and hepatologists are required for better management of hospitalized ESLD patients comorbid with AF.

OBJECTIVE: Aphasia is one of the most severe symptoms in stroke patients, affecting one-third of acute stroke patients. We aimed to investigate the prevalence and outcomes of aphasia in patients with acute ischemic stroke (AIS). METHODS: We computed the weighted prevalence of aphasia in AIS patients using the 2003 to 2014 National Inpatient Sample databases. Crude regression model, multivariable regression model, and propensity score matching were used to evaluate the impact of aphasia on the clinical outcomes in AIS patients. We performed the Subpopulation Treatment Effect Pattern Plot (STEPP) analyses in propensity score matching cohort to visually display the effect of interaction between aphasia and age on the clinical outcomes. RESULTS: A total of 16.93% of 4,339,156 AIS patients identified were with aphasia. The proportion of patients with comorbid aphasia increased from 13.34% in 2003 to 21.94% in 2014 (P < .0001). The results of both multivariable regression model and propensity score matching analyses indicated aphasia in AIS as a risk factor for in-hospital deaths. Aphasia was linked to prolonged length of stay (0.66 day, P < .0001) and high hospitalization cost ($971.35, P < .0001). In the STEPP analyses, in-hospital mortality rate increased with age, and the rate was higher in patients with aphasia, but the ratios decreased with an increase in age. CONCLUSIONS: Prevalence of comorbid aphasia with AIS is increasing, and it has a significant impact on clinical outcomes. Additionally, aphasia shows a greater impact on survival and medical burden among young patients with AIS.

PURPOSE: To make a further evaluation of perioperative outcomes between the robot-assisted radical prostatectomy (RARP) and open radical prostatectomy (ORP), we conducted a comparison and trend analysis by using the Nationwide Inpatient Sample (NIS) from 2009 to 2014. MATERIALS AND METHODS: Adult prostate cancer patients with radical prostatectomy were abstracted from the NIS. RARP and ORP were identified according to the International Classification of Diseases, 9th Revision, Clinical Modification procedure codes. The perioperative outcomes included blood transfusion, intraoperative and postoperative complications, prolonged length of stay (pLOS), and in-hospital mortality. Propensity score matching method and multivariable logistic regression model were performed to adjust for the pre-defined covariates. The annual percent change (APC) was used to detect the change trend of rates for outcomes. RESULTS: A total of 77.054 patients were included in our study. According to the results of propensity score matching analyses, RARP outperformed ORP in blood transfusion (1.96% vs. 9.40%), intraoperative complication (0.73% vs. 1.25%), overall postoperative complications (8.87% vs. 11.97%), and pLOS (13.39% vs. 36.70%). We also found that there was a significant decreasing tendency of incidence in blood transfusion (APC=-9.81), intraoperative complication (APC=-12.84), and miscellaneous surgical complications (APC=-14.09) for the RARP group. The results of multivariable analyses were almost consistent with those of propensity score matching analyses. CONCLUSIONS: The RARP approach has lower incidence rates of perioperative complications than the ORP approach, and there is a potential decreasing tendency of complication incidence rates for the RARP.

Background: inhibition of acetylcholinesterase (AChE) has been a effective treatment for Alzheimer's disease (AD). Octohydroaminoacridine, a new AChE inhibitor, is a potential treatment for AD. Method: we conducted a multicenter, randomised, double blind, placebo-controlled, parallel-group Phase II clinical trial to investigate the effects of octohydroaminoacridine in patients with mild-to-moderate AD. Patients were randomised to receive placebo thrice daily, octohydroaminoacridine 1 mg/thrice daily (TID) (low-dose group), 2 mg/TID (middle-dose group) or 4 mg/TID (high-dose group). Doses in the middle-dose and high-dose group were titrated over 2-4 weeks. Changes from baseline to Week 16 were assessed with the AD Assessment Scale-Cognitive Subscale (ADAS-cog), Clinician's Interview-Based Impression of Change Plus (CIBIC+), activities of daily living (ADL) and the neuropsychiatric inventory (NPI). ADAS-cog was the primary end point of the study. A two-way analysis of covariance and least squares mean t-test were used. Results: at Week 16, the changes from baseline in ADAS-cog were 1.4, -2.1, -2.2 and -4.2 for placebo, low-, middle- and high-dose groups, respectively. Patients in the high-dose group had better performance in CIBIC+ and ADL scores at the end of the study. There was no significant difference in the change in NPI score among the groups. The effects of octohydroaminoacridine were dose dependent, and were effective within 16 weeks of treatment. No evidence was found for more adverse events that occurred in different drug groups than placebo group. Conclusions: octohydroaminoacridine significantly improved cognitive function and behaviour in patients with mild-to-moderate AD and this effect was dose dependent.

BACKGROUND: Stroke causes death and disability throughout the world and recurrent stroke events are more likely to be disabling or fatal. We conducted a hospital-based study to investigate the frequency and influence factors of stroke recurrence in China. METHODS: Data from patients hospitalized with stroke between January 2007 and December 2010 of 109 tertiary hospitals in China were used. Stroke recurrence and associated factors were ascertained. The zero-inflated model was used to evaluate the factors of recurrence. RESULTS: Of 101,926 discharged patients, the cumulative 2-year stroke recurrence rate was 3.80% for subarachnoid hemorrhage (SAH), 5.31% for intracerebral hemorrhage (ICH), and 8.71% for ischemic stroke (IS), respectively. Among patients with stroke recurrence, 54.11% with SAH, 60.42% with ICH, and 92.92% with IS relapsed for the same type of the first-onset stroke. For discharged patients with SAH with middle cerebral artery aneurysm clipping or artery aneurysm embolization, it was less likely to stroke relapse, but the times of recurrence would increase if 1 recurrence appeared. Cerebral artery aneurysms and hypertension were risk factors for recurrence frequency. For ICH, protective factors for recurrence were trepanation and drainage of intracranial hematoma, cerebral angiography, puncture and drainage of intracranial hematoma, and length of stay (LOS). But rheumatic heart disease and atrial fibrillation would further the relapse frequency. For IS, age and LOS were protective factors, but recurrence frequency would increase if the first recurrence happened. Cervical spondylopathy, male gender, and diabetes were risk factors for frequency of relapse. CONCLUSIONS: Associated factors were different for recurrence frequency among different stroke types.

This study investigated the association between adult weight gain and risk of colorectal cancer (CRC). Using terms related to weight gain and CRC, we searched PubMed, Embase and Web of Science for relevant studies published before June 2014. Two evaluators independently selected studies according to the selection criteria, and eight studies were included (three case-control and five cohort studies). Summary estimates were obtained using fixed- or random-effects models. The relative risk (RR) of the association between adult weight gain and CRC was 1.25 (95% confidence interval [CI], 1.10-1.43); the RR was 1.30 (95% CI, 1.14-1.49) for colon cancer (CC) and 1.27 (95% CI, 1.02-1.58) for rectal cancer (RC) for the highest versus lowest category. For every 5-kg increase in adult weight, the risk increased by 5% (RR, 1.05; 95% CI, 1.02-1.09) for CRC, 6% (RR, 1.06; 95% CI, 1.02-1.11) for CC and 6% (RR, 1.06; 95% CI, 1.03-1.08) for RC. The subgroup analyses showed a positive association between adult weight gain and risk of CRC only in men, and the RR was 1.65 (95% CI, 1.42-1.92) for the highest versus lowest category of adult weight gain and 1.10 (95% CI, 1.06-1.15) for a 5-kg increase in adult weight. In conclusion, there is evidence that adult weight gain is associated with an increased risk of CRC. However, the positive association between adult weight gain and risk of CRC is stronger among men than among women.

Studies that investigated the association between tea consumption and the risk of major cardiovascular events have reported inconsistent results. We conducted a meta-analysis of prospective observational studies in order to summarize the evidence regarding the association between tea consumption and major cardiovascular outcomes or total mortality. In July 2014, we performed electronic searches in PubMed, EmBase, and the Cochrane Library, followed by manual searches of reference lists from the resulting articles to identify other relevant studies. Prospective observational studies that reported effect estimates, with 95% confidence intervals (CIs), for coronary heart disease (CHD), stroke, cardiac death, stroke death, or total mortality for more than two dosages of tea consumption were included. A random-effects meta-analysis was performed to determine the risk of major cardiovascular outcomes associated with an increase in tea consumption by 3 cups per day. Of the 736 citations identified from database searches, we included 22 prospective studies from 24 articles reporting data on 856,206 individuals, and including 8,459 cases of CHD, 10,572 of stroke, 5,798 cardiac deaths, 2,350 stroke deaths, and 13,722 total deaths. Overall, an increase in tea consumption by 3 cups per day was associated with a reduced risk of CHD (relative risk [RR], 0.73; 95% CI: 0.53-0.99; P = 0.045), cardiac death (RR, 0.74; 95% CI: 0.63-0.86; P < 0.001), stroke (RR, 0.82; 95% CI: 0.73-0.92; P = 0.001), total mortality (RR, 0.76; 95% CI: 0.63-0.91; P = 0.003), cerebral infarction (RR, 0.84; 95% CI: 0.72-0.98; P = 0.023), and intracerebral hemorrhage (RR, 0.79; 95% CI: 0.72-0.87; P < 0.001), but had little or no effect on stroke mortality (RR, 0.93; 95% CI: 0.83-1.05; P = 0.260). The findings from this meta-analysis indicate that increased tea consumption is associated with a reduced risk of CHD, cardiac death, stroke, cerebral infarction, and intracerebral hemorrhage, as well as total mortality.

Studies on the association of short or long sleep duration with breast cancer risk have reported inconsistent results. We quantitatively assessed this association by conducting a meta-analysis based on the evidence from observational studies. In April 2013, we performed electronic searches in PubMed, EmBase and the Cochrane Library to identify studies examining the effect of sleep duration on breast cancer incidence. The odds ratio (OR) was used to measure any such association in a random-effects model. The analysis was further stratified by confounding factors that could bias the results. A total of six studies (two case-control and four cohort studies) involving 159,837 individuals were included in our meta-analysis. Our study did not show an association between either short or long sleep duration and breast cancer risk (short sleep duration data: pooled OR = 1.01, 95% confidence interval (CI) = 0.90-1.14, p = 0.853; long sleep duration data: pooled OR = 0.95, 95% CI = 0.86-1.04, p = 0.251). Moreover, we did not identify any statistically significant association between sleep duration and breast cancer risk in all the subgroup analyses. In conclusion, our findings indicate that sleep duration has no effect on breast cancer risk.

BACKGROUND: Statins are commonly used to lower total cholesterol levels in the general population to prevent cardiovascular events. However, the effects of statins in patients with chronic kidney disease remain unclear. We therefore performed a meta-analysis to assess the effects of statin therapy on cardiovascular outcomes in patients with mild to moderate chronic kidney disease. METHODS: We systematically searched PubMed, EmBase, the Cochrane Central Register of Controlled Trials, proceedings of major meetings, and reference lists of articles for relevant literature. Only randomized clinical trials were included. Outcomes analysed included cardiovascular disease, total mortality, myocardial infarction, stroke, cardiovascular death, and possible drug-related adverse events. Subgroup analyses were also performed based on the population characteristics and clinical indexes. RESULTS: Twelve trials met our inclusion criteria. Overall, statin therapy resulted in a 24% reduction in the risk of cardiovascular disease (RR = 0.76,95% confidence interval [CI], 0.72- 0.80), a 21% reduction in the risk of total mortality (RR = 0.79,95% CI, 0.72-0.86), a 34% reduction in the risk of myocardial infarction (RR = 0.66,95% CI, 0.52-0.83), a 30% reduction in the risk of stroke (RR = 0.70,95% CI, 0.57-0.85), and a 17% reduction in the risk of cardiovascular mortality (RR = 0.83,95% CI, 0.73- 0.93). No statistically significant drug-related adverse events were noted. Subgroup analysis indicated that some important factors such as baseline creatinine level ≥1.5 mg/dL, baseline glomerular filtration rate (GFR), and cardiovascular disease history could affect cardiovascular outcomes. CONCLUSION: Statin therapy had a clear effect on cardiovascular disease, total mortality, stroke, and myocardial infarction in patients with mild to moderate renal disease. Subgroup analysis indicated that baseline GFR, baseline creatinine level, and a history of cardiovascular disease might play an important role in the cardiovascular outcomes.

BACKGROUND: The optimal proximal margin (PM) length for Siewert II/III adenocarcinoma of the esophagogastric junction (AEJ) remains unclear. This study aimed to determine the optimal PM length using an abdominal approach to guide surgical decision-making. METHODS: A prospective study analyzed 304 consecutive patients diagnosed with Siewert II/III AEJ between January 2019 and December 2021. Total gastrectomy was performed via the abdominal approach, and PM length was measured on fixed gross specimens. X-Tile software determined the optimal PM cut-point based on progression-free survival (PFS). Univariate analyses compared baseline characteristics across PM groups, while survival analyses utilized Kaplan-Meier estimation and Cox proportional hazards regression for assessing the impact of margin length on survival. Multivariable analyses were conducted to adjust for confounding variables. RESULTS: The study included 264 AEJ cases classified as Siewert II (71.97%) or III (28.03%). The median gross PM length was 1.0 cm (IQR: 0.5 cm-1.5 cm, range: 0 cm-6 cm). PM length ≥1.2 cm was associated with a lower risk of disease progression compared to PM length 0.4 cm on PFS (HR = 0.41, 95% CI 0.20-0.84, P = 0.015). Moreover, PM ≥ 1.2 cm improved prognosis in subgroups of T4 or N3, tumor size <4 cm, Siewert II, and Lauren classification. CONCLUSIONS: For Siewert type II/III AEJ, a proximal margin length ≥1.2 cm (1.65 cm in situ) is associated with improved outcomes. These findings offer valuable insights into the association between PM length and outcomes in Siewert II/III AEJ, providing guidance for surgical approaches and aiding clinical decision-making to enhance patient outcomes.

OBJECT: The association between magnesium depletion score (MDS) and kidney stone disease (KSD) remains unknown. This study was designed to investigate the association of MDS with KSD in adults. METHODS: A total of 19,654 participants were enrolled from the National Health and Nutrition Examination Surveys (NHANES). The MDS was calculated by assessing four aspects, including alcohol assumption, renal function, and use of diuretics and proton pump inhibitor. Multivariable logistic regressions were performed to explore the associations between MDS and the prevalence of KSD. Linear correlations were conducted explore the relationship of testosterone with MDS. RESULTS: In the multivariable logistic regressions with full adjustment for confounding variables, the odds ratio of MDS associating with KSD was 1.28 (95% CI: 1.04-1.58, P = 0.022) in total population, and 1.70 (95% CI: 1.16-2.50, P=0.007) in female participants. Besides, compared to the lowest MDS, the highest MDS was associated with a lower testosterone (ß = -16.39, P=0.009) after full adjustment in non-menopause women. CONCLUSION: This study highlighted a positive correlation of high MDS with KSD in female population, which may be associated low level of serum testosterone.

The composite dietary antioxidant index (CDAI) is commonly utilized to assess antioxidant intake across diseases, but its association with kidney stones is unclear. We hypothesized that higher CDAI is associated with reduced kidney stone risk. Using National Health and Nutrition Examination Survey 2007-2020 data, we calculated CDAI based on vitamins A, C, E, selenium, zinc, and carotenoids intake in 29,280 adults. Stone formers had lower CDAI, with significant gender differences. Restricted cubic spline showed an L-shaped curve, with the steepest decline before CDAI of 1.449. In multivariate logistic regression, moderate and high CDAI tertiles were associated with reduced kidney stone odds compared to the lowest tertile (odds ratio [95% CI]): 0.85 [0.73, 0.99], P = .035 and 0.80 [0.66, 0.95], P = .014, respectively). Vitamin C had the highest negative correlation weight with kidney stones. Significant interactions were found for age and diabetes subgroups. In conclusion, higher CDAI may reduce kidney stone risk, especially with adequate vitamin C intake. Further cohort studies are warranted to confirm the causal association.
