Diverse Intimate Partner Violence Survivors' Experiences Seeking Help from the Police: A Qualitative Research Synthesis.

Intimate partner violence (IPV), inclusive of all forms of abuse, is an ongoing public health and criminal-legal issue that transcends social boundaries. However, there is a lack of equitable representation of diverse populations who experience IPV in the literature. To garner a holistic knowledge of diverse IPV survivor populations' experiences with seeking help from the police, the current review utilized a qualitative research synthesis methodology to explore police interactions among six IPV survivor populations that are underrepresented in the current literature: women with substance use issues, immigrant women, women in rural localities, heterosexual men, racially/ethnically minoritized women, and sexual minority women. Seven electronic databases were searched to identify peer-reviewed articles on IPV survivors' narrative descriptions (qualitative or mixed-methods) of their encounters with law enforcement. The final analysis included 28 studies that were then coded with an iterative coding strategy. The analysis uncovered the following themes: (a) revictimization by the police, (b) police negligence, (c) discrimination, (d) cultural differences, and (e) positive experiences. These themes demonstrated that while some experiences with law enforcement were shared between under-researched survivor groups, some experiences were explicitly tied to some aspects of survivors' identities. Recognizing the potential law enforcement has to support survivors, the findings of the current review reiterate the need for ongoing efforts to improve law enforcement knowledge and overall response to IPV, especially for diverse populations of IPV survivors.

Effects of a Single Session of Mindfulness and Compassion on Skin Temperature in Breast Cancer Survivors.

Previous studies have suggested that mindfulness programs can be useful, in a significant sector of the population, to reduce stress when practiced for at least 8 weeks. The objective of the present investigation was to explore the effect of a single session of mindfulness practice in reducing stress in female cancer survivors. Two repeated measures studies were applied; in the first one, it was performed individually, while in the second one, it was performed in a group. Psychosocial measures were administered, and skin temperature was recorded as a marker of autonomic nervous activity. The results indicate that only when the mindfulness exercise was presented did the skin temperature increase (p < 0.05), with a large effect size (d > 0.8) during compassion, suggesting sympathetic decline. Furthermore, the psychosocial functioning of the group of female cancer survivors was like that of the non-clinical population. The data are discussed in the context of Polyvagal Theory, a theoretical model of biopsychosocial functioning, and evidence is provided on the effect of mindfulness and compassion on reducing stress and inducing positive affect in female cancer survivors.

Low thoracic skeletal muscle is a risk factor for 6-month mortality of severe community-acquired pneumonia in older men in intensive care unit

BackgroundPatients with severe community-acquired pneumonia (sCAP) admitted to the intensive care unit (ICU) often exhibit muscle catabolism, muscle weakness, and/or atrophy, all related to an increased morbidity and mortality. However, the relationship between thoracic skeletal muscle mass and sCAP-related mortality has not been well-studied. Early recognition of sarcopenia in ICU patients with sCAP would benefit their prognosis.MethodsA retrospective study was conducted in Taizhou Hospital of Zhejiang Province, involving 101 patients with sCAP admitted in the ICU between December 2022 and February 2023. We measured the cross-sectional aera of the pectoralis, intercostal, paraspinal, serratus, and latissimus muscles at the T4 vertebral level (T4CSA) using chest computed tomography. Discriminatory thresholds were established by performing receiver operating characteristic curve analysis, with a designated cutoff value of 96.75 cm2 for male patients. This cohort was classified into mortality and survival groups based on a 6-month post-admission outcome. Univariate and multifactorial logistic regression analyses were performed to validate the correlation between low thoracic skeletal muscle area and prognostic outcomes.ResultsThe mean age of the patients was 75.39 ± 12.09 years, with an overall 6-month mortality of 73.27%. T4CSA of the 6-month survival group was significantly larger than that in the mortality group for overall cohort. The T4CSA in the survival group was significantly larger than that in the mortality group (104.29 ± 23.98cm2 vs. 87.44 ± 23.0cm2, p = 0.008). T4CSA predicted the 6-month mortality from sCAP in males with an AUC of 0.722 (95% confidence interval (CI), 0.582–0.861). The specificity and sensitivity were 71.4% and 71.1%, respectively, (p < 0.05). No significant difference was observed between the two groups in terms of T4CSA.ConclusionsThis study revealed that low thoracic skeletal muscle mass increased the risk of all-cause 6-month mortality in ICU patients with sCAP, particularly among male patients.

Induction chemoimmunotherapy followed by radiotherapy in locally advanced head and neck squamous cell carcinoma: A real-world study.

131 Background: Patients with locally advanced head and neck squamous cell cancers (LAHNSCC) present poor prognosis despite multi-disciplinary comprehensive treatment, and novel treatment strategies are urgently needed. Recently, several phase II clinical trials reported encouraging pathological complete response rate of induction chemoimmunotherapy (IC+ICI) in LAHNSCC, suggesting potentially long-term survival benefits. Therefore, we conducted this real-world study to compare the efficacy of IC+ICI followed by radiotherapy (RT) versus induction chemotherapy (IC) followed by RT in LAHNSCC. Methods: We retrospectively included patients with LAHNSCC from Sun Yat-sen University Cancer center database treated with IC+ICI followed by RT or IC followed by RT between 1/2018-12/2021. Survival outcomes and adverse effects (AEs) were compared between the two groups. Results: A total of 262 patients were included: 128 (48.9%) in the IC+ICI group, and 134 (51.1%) in the IC group. Median age for the whole cohort was 60 (53–66) years, and the male-to-female ratio is 8.9:1. Most patients (84.4%) had stage IV disease. The median follow-up time was 26.7 (IQR 25.8-29.6) months. Marginally significant higher objective response rate (ORR) was observed in the IC+ICI group than that in the IC group (81.25% vs 72.39%, P=0.09). Patients in the IC+ICI group had significantly better results than those in the IC group in 2-year overall survival (OS; 88.9% vs. 71.5%, P&lt;0.001), disease-free survival (DFS; 77.5% vs. 58.3%, P=0.005), locoregional relapse-free survival (LRRFS; 78.4% vs. 59.7%, P=0.009) and distant metastasis-free survival (DMFS; 87.5% vs. 64.6%, P&lt;0.001). Multivariate analysis confirmed that combining immunotherapy in the induction stage was an independent prognostic factor for OS (HR 0.40, 95%CI 0.19-0.84), DFS (HR 0.45, 95%CI 0.28-0.72), LRRFS (HR 0.56, 95%CI 0.31-0.99), and DMFS (HR 0.37, 95%CI 0.19-0.73). The incidences of G3/4 AEs between the IC+ICI group and the IC group were comparable during the induction stage (6.25% vs 12.69%, P = 0.076) as well as the radiotherapy stage (14.06% vs 14.18%, P = 0.978). Conclusions: This study firstly reported that IC+ICI followed by RT was superior to IC followed by RT in long-term survival outcome in LAHNSCC.

Pretreatment CT-based machine learning radiomics model to predict response in unresectable hepatocellular carcinoma treated with lenvatinib plus PD-1 inhibitors and interventional therapy.

94 Background: Lenvatinib plus PD-1 inhibitors and interventional (LPI) therapy has demonstrated promising treatment effects in unresectable hepatocellular carcinoma (uHCC). However, biomarkers for predicting the response to LPI therapy remained to be further explored. The current study aimed to develop a radiomics model to noninvasively predict the efficacy of LPI therapy for uHCC. Methods: Clinical data of patients who were diagnosed with uHCC and accepted LPI therapy were collected in our institution. The clinical model was built by clinicopathological information. Nine machine learning classifiers were tested and the multilayer perceptron classifier with optimal performance was utilized as the radiomics model. The clinical-radiomics model was constructed by integrating clinical and radiomics scores. Results: 151 patients were enrolled in this study (2:1 randomization, 101 and 50 in the training and validation cohorts), of which three patients achieved complete response, 69 showed partial response, 46 showed stable disease and 33 showed progressive disease (evaluated by mRECIST criteria). The objective response rate (ORR), disease control rate (DCR), and conversion resection rate were 47.7, 78.1 and 23.2%, respectively. 14 features were selected from the initially extracted 1223 for radiomics model construction. The area under the curves of the radiomics model (0.900 for training and 0.893 for validation) were comparable to that of the clinical-radiomics model (0.912 for training and 0.892 for validation), and both were superior to the clinical model (0.669 for training and 0.585 for validation). Meanwhile, the radiomics model could categorize participants into high- and low-risk groups for progression-free survival and overall survival in the training and validation sets. Conclusions: The current study developed a novel and promising machine learning radiomics model, which could efficiently predict the efficacy of LPI therapy for uHCC, with comparable performance to clinical-radiomics model.

Predictive ability of the REMS and HOTEL scoring systems for mortality in geriatric patients with pulmonary embolism

BackgroundPulmonary embolism (PE) is an important cause of mortality and morbidity in the geriatric population. We aimed to compare the ability of the pulmonary embolism severity index (PESI), rapid emergency medicine score (REMS), and hypotension, oxygen saturation, low temperature, electrocardiogram change, and loss of independence (HOTEL) to predict prognosis and intensive care requirement in geriatric patient with PE.ResultsThe median age of 132 patients was 77 (71–82) years. PESI was higher in the non-survivor group [132 (113–172)] (P =0.001). The median REMS was 8 (7–10), and it was higher in the non-survivor group [10 (7.5–12.0)] (p = 0.005). The median HOTEL score was 1 (0–2) in the whole cohort and 2 (1–3) in the non-survivor group, indicating significant difference compared to the survivor group (P = 0.001). The area under the curve (AUC) values of HOTEL, REMS, and PESI were determined as 0.72, 0.65, and 0.71, respectively. For the prediction of intensive care requirement, the AUC values of HOTEL, REMS, and PESI were 0.76, 0.75, and 0.76, respectively, with no significant difference in pairwise comparisons (PESI vs. REMS: p = 0.520, HOTEL vs. PESI: P = 0.526, REMS vs. HOTEL: P = 0.669, overall test: P = 0.96, DeLong’s test). The risk ratios of HOTEL and PESI were parallel to each other [5.31 (95% confidence interval (CI): 2.53–11.13) and 5.34 (95% CI: 2.36–12.08), respectively].ConclusionHOTEL and REMS were as successful as PESI in predicting short-term mortality and intensive care requirement in geriatric patients with PE. These scores are also more practical since they have fewer parameters than PESI.

Tobacco-cannabis co-use among cancer patients and survivors: findings from 2 US cancer centers.

Cannabis use is prevalent among cancer patients and survivors and may provide some therapeutic benefits for this population. However, benefits may be attenuated when cannabis is co-used with tobacco, which is associated with more severe tobacco and cannabis use and adverse outcomes in noncancer populations. We compared cannabis use, primary mode of use, and therapeutic and/or nontherapeutic use among 3 groups of patients and survivors based on cigarette smoking status. Survey data was collected from patients and survivors with cancer (n = 1732) at 2 US National Cancer Institute-designated cancer centers in states with varying cannabis regulatory policy. Prevalence of cannabis use (prior to diagnosis, after diagnosis, before treatment, after treatment), primary mode of use, and therapeutic and/or nontherapeutic use were assessed by cigarette smoking status (current, former, never) within and across centers using weighted bivariate analyses and multivariable logistic regression, controlling for demographic and clinical variables. Current cigarette use was associated with greater rates of cannabis use prior to diagnosis, after diagnosis, during treatment, and after treatment within each center (all P < .001) and in pooled analyses across centers (all P < .001). Primary mode of use, knowledge of cannabis products, and therapeutic and/or nontherapeutic use also statistically differed by tobacco status and study site. Results illustrate the importance of conducting assessments for both tobacco and cannabis use among cancer patients during and after cancer treatment, regardless of the cannabis regulatory environment. Given previous data indicating harms from co-use and continued tobacco use during cancer treatment, this issue introduces new priorities for cancer care delivery and research.

Glucocorticoid Sensitivity Among Young Survivors of Childhood Acute Lymphoblastic Leukemia: What Does It Matter?

The aim of the study was to assess glucocorticoid sensitivity in survivors of childhood acute lymphoblastic leukemia using in vivo and in vitro tests. Thirty leukemia survivors of both sexes aged ≥18 years participated in the study and at least two years after therapy withdrawal. In vivo tests comprised: a) a very low dose intravenous dexamethasone suppression test for measurement of serum cortisol before, after, and % suppression, compared with 32 age-matched controls; and b) 0.25 mg overnight oral dexamethasone suppression test for assessment of salivary cortisol before, after, and % suppression. In vitro methods comprised: c) glucocorticoid receptor polymorphisms: BcI1-NR3C1 and A3669G; and d) splicing variant of glucocorticoid receptor GR-α mRNA by real-time quantitative polymerase chain reaction, compared with 32 controls. There was a reduction in salivary cortisol, and 73.3% of leukemia survivors showed high sensitivity according to % suppression after oral dexamethasone (p<0.05). Serum cortisol at baseline, after the test, % suppression after intravenous dexamethasone, and the percentage of high sensitivity were reduced in the leukemia group (%F=36.7; p<0.05). The BcI1-NR3C1 and A3669G polymorphisms were present in 11/30 (36.7%) and 5/30 (16.7%) patients, respectively. GR-α mRNA levels were lower in the leukemia group than in the controls (p<0.05). Survivors of acute lymphoblastic leukemia presented with reduced glucocorticoid sensitivity. Glucocorticoid sensitivity allows individualized treatment to avoid adverse effects and may be involved in cardiovascular disease risk among this particular group of cancer survivors.

6 Durable response to immunotherapy-based regimens for IMDC favorable risk patients with metastatic clear cell renal cell carcinoma: a pooled analysis of four published randomized control phase 3 trials

Abstract Background An immune checkpoint inhibitor (ICI) backbone of either ICI doublet (ipilimumab-nivolumab [ipi-nivo]) or tyrosine kinase inhibitor (TKI) with ICI (such as axitinib-pembrolizumab [axi-pembro], cabozantinib-nivolumab [cabo-nivo], or lenvatinib-pembrolizumab [len-pembro]) is the current standard of care for previously untreated, metastatic clear cell renal cell carcinoma (mccRCC). The phase 3 trials that evaluated these four regimens were compared to sunitinib, with no direct head-to-head clinical trial data available. With at least 4-year follow up data available, we compared the long-term responders of the IMDC favorable risk patients enrolled in the four phase 3 trials (CheckMate 214, KEYNOTE-426, CheckMate 9ER, and CLEAR). Methods Pseudo individual patient data (IPD) was obtained from the Kaplan-Meier (K-M) curves using the graph digitizer software IPDfromKM R package to extract coordinates of points on the curves and applied the numerical algorithm to reconstruct survival results. The hazard ratios (HRs) of the favorable risk group for both progression-free survival (PFS) and overall survival (OS) comparing the experimental arms to sunitinib were extracted. Responses were measured at 24 (durable response [DR]) and 36 months (extreme durable response [EDR]) and long-term OS as OS ≥48 months. K-M method using the extracted IPD was used to estimate the survival rates at 24-month PFS, 36-month PFS, and 48-month OS. Then, we compared the survival rates at each time point using the generalized linear model for the survival rates at fixed time points obtained from the K-M method. Results Len-pembro was associated with the highest DR (57.2%) and EDR (44.5%), while ipi-nivo had the lowest DR (36.0%), and cabo-nivo had the lowest EDR (18.8%). There was no difference in 48 month-OS among regimens (p=0.11), ranging between 58.3% (cabo-nivo) and 70.6% (len-pembro). Comparing the sunitinib control arms among the four studies, a numerically higher PFS at 24 months (59%) and 36 months (40%) was observed in the CheckMate 214 trial compared to the ICI-TKI trials (25-35% and 15-20%, respectively). The 48-month OS for the sunitinib arms ranged from 55-70%, and no differences were observed among trials (p=0.55). Comparisons of survival rates for the immunotherapy arm on fixed time-points for IMDC favorable risk subset of patients Conclusions ICI-based regimens provided durable responses to a significant number of patients with favorable risk mccRCC. While TKI-ICI were associated with higher DR and EDR, no differences in OS at 48 months were observed compared to ipi-nivo or sunitinib for favorable risk disease. Longer follow-up is necessary to evaluate long-term outcomes given the favorable prognosis of these patients. We acknowledge the limitations and caveats of cross-trial comparisons.

Laparoscopic Versus Open Nephroureterectomy for Upper Tract Urothelial Carcinoma: A Systematic Review and Meta-Analysis of Propensity-Score Matched Studies.

The effectiveness of laparoscopic nephroureterectomy (LNU) vs open nephroureterectomy (ONU) for upper tract urothelial carcinoma (UTUC) is unclear. We conducted a meta-analysis of studies based on propensity score-matched cohorts to compare the surgical and oncological outcomes of LNU and ONU in UTUC patients. A literature search was conducted on PubMed, Embase, and Cochrane Library until July 12, 2023. The Newcastle-Ottawa Scale was utilized to assess the quality of eligible studies. Measurements of surgical and oncological outcomes were extracted and pooled including mean difference (MD), risk ratio (RR), hazard ratios (HR), and 95% confidence intervals (CI). Five high-quality retrospective studies were included, totaling 6422 patients; 2080 (32.4%) underwent LNU, and 4342 (67.6%) underwent ONU. With respect to surgical outcomes, patients in the LNU group experienced less estimated blood loss and had shorter hospital stay than those in the ONU group, but there was no significant difference in complication rates and operation time. In regard to oncological outcomes, there were no significant differences between the LNU and ONU groups in 3-year overall survival (OS) and cancer-specific survival (CSS). However, 3-year intravesical recurrence free survival (IVRFS) was worse in the LNU group compared to the ONU group. LNU was associated with less estimated blood loss and shorter hospital stays than ONU, but there were no differences in OS and CSS between the surgical modalities. Nonetheless, LNU might result in poorer IVRFS than ONU.

Impact of the quantity and quality of erector spinae muscles on the short-term prognosis of elderly patients with aspiration pneumonia in Japan

BackgroundWhether muscle mass and muscle quality affect the prognosis of elderly patients with aspiration pneumonia is unclear. This study aimed to evaluate the relationship between erector spinae muscle mass and muscle quality on the 30-day prognosis of elderly patients with aspiration pneumonia. MethodsTwo hundred fifty-eight patients who were diagnosed with aspiration pneumonia and admitted to Sanuki Municipal Hospital for pulmonary rehabilitation intervention were included. The cross-sectional area (ESMCSA/BSA) and CT values (ESMCT) of the erector spinae muscles at the 12th thoracic vertebra were measured on chest CT images to represent muscle mass and quality, respectively. The primary outcome was defined as 30-day survival. ResultsTwenty-six patients died within 30 days after hospitalization. The ESMCSA/BSA ratio was significantly greater in the survival group than in the nonsurvival group (p = 0.001). The cutoff values for 30-day survival were calculated as follows: the ESMCSA/BSA was 11.046 cm2/m2 in male patients and 9.600 cm2/m2 in female patients; the ESMCT was 26.85 HU in male patients and 8.00 HU in female patients. A higher ESMCSA/BSA significantly improved 30-day survival, while ESMCT did not show a significant difference. Cox proportional hazards regression analysis revealed that the ESMCSA/BSA was independently associated with 30-day short-term prognosis (hazard ratio 0.34, p = 0.034). ConclusionThe short-term prognosis of elderly patients with aspiration pneumonia may be more strongly influenced by muscle mass than by the muscle quality of the erector spinae muscles.

Application of the Unbalanced Ensemble Algorithm for Prognostic Prediction Outcomes of All-Cause Mortality in Coronary Heart Disease Patients Comorbid with Hypertension.

This study sought to develop an unbalanced-ensemble model that could accurately predict death outcomes of patients with comorbid coronary heart disease (CHD) and hypertension and evaluate the factors contributing to death. Medical records of 1058 patients with coronary heart disease combined with hypertension and excluding those acute coronary syndrome were collected. Patients were followed-up at the first, third, sixth, and twelfth months after discharge to record death events. Follow-up ended two years after discharge. Patients were divided into survival and nonsurvival groups. According to medical records, gender, smoking, drinking, COPD, cerebral stroke, diabetes, hyperhomocysteinemia, heart failure and renal insufficiency of the two groups were sorted and compared and other influencing factors of the two groups, feature selection was carried out to construct models. Owing to data unbalance, we developed four unbalanced-ensemble prediction models based on Balanced Random Forest (BRF), EasyEnsemble, RUSBoost, SMOTEBoost and the two base classification algorithms based on AdaBoost and Logistic. Each model was optimised using hyperparameters based on GridSearchCV and evaluated using area under the curve (AUC), sensitivity, recall, Brier score, and geometric mean (G-mean). Additionally, to understand the influence of variables on model performance, we constructed a SHapley Additive explanation (SHAP) model based on the optimal model. There were significant differences in age, heart rate, COPD, cerebral stroke, heart failure and renal insufficiency in the nonsurvival group compared with the survival group. Among all models, BRF yielded the highest AUC (0.810; 95% CI, 0.778-0.839), sensitivity (0.990; 95% CI, 0.981-1.000), recall (0.990; 95% CI, 0.981-1.000), and G-mean (0.806; 95% CI, 0.778-0.827), and the lowest Brier score (0.181; 95% CI, 0.178-0.185). Therefore, we identified BRF as the optimal model. Furthermore, red blood cell count (RBC), body mass index (BMI), and lactate dehydrogenase were found to be important mortality-associated risk factors. BRF combined with advanced machine learning methods and SHAP is highly effective and accurately predicts mortality in patients with CHD comorbid with hypertension. This model has the potential to assist clinicians in modifying treatment strategies to improve patient outcomes.

Patients With Dysplasia Achieve Similar Outcomes and Survivorship to Nondysplastic Patients 10 Years After Hip Arthroscopy for Femoroacetabular Impingement

To determine the long-term outcomes of hip arthroscopy (HA) for femoroacetabular impingement (FAI) in the presence of concomitant lateral rim dysplasia compared with a matched control group. Patients undergoing HA between January 2009 and October 2013 with minimum 10-year follow-up were reviewed. The inclusion criteria consisted of patients undergoing HA for FAI with evidence of lateral rim dysplasia (lateral-center edge angle [LCEA] < 25°). Patients with lateral rim dysplasia were matched to patients with an LCEA greater than 30° based on sex, Tönnis grade, and age. Outcomes included survival (avoidance of total hip replacement [THR]), repeated HA, and patient-reported outcomes (PROs). Survivorship was assessed using a Kaplan-Meier curve and log rank test, whereas revision rates between groups were assessed using χ2 analysis. Between- and within-group analyses of PROs were conducted using the Mann-Whitney U test and Wilcoxon signed rank test, respectively. The proportion of cases achieving the patient acceptable symptom state was compared between groups using χ2 analysis. This study comprised 46 dysplasia cases and 90 control cases. There was no statistically significant difference between groups in baseline metrics apart from the LCEA (P < .001), Sharp angle (P < .001), and Tönnis angle (P < .001). By 10 years postoperatively, 9% of dysplasia cases and 4% of control cases underwent conversion to THR. There was no statistically significant difference between groups in survival or revision rates. Both groups reported improvements in PROs, and there was no difference between PRO scores at either time point. Excluding cases that underwent THR, 84% and 83% of dysplasia and control cases, respectively, achieved the patient acceptable symptom state. HA for symptomatic FAI is a successful treatment in cases in which dysplasia is present. Low complication rates, comparable outcomes to cases without lateral rim dysplasia, and a high survivorship rate of 91% at minimum 10-year follow-up are observed. Increasing Tönnis angle preoperatively may increase the risk of THR conversion. Level IV, retrospective cohort study.

Analysis of pathogen distribution and sTREM-1 and miR-126 levels in patients with pulmonary infection after craniocerebral injury.

sTREM-1H and miR-126 play crucial roles in inflammation and immune responses, yet their involvement in patients with pulmonary infection following cranial injury remains understudied. The distribution of pathogens causing infection in patients with pulmonary infection after craniocerebral injury was explored, and the changes in the levels of soluble triggering receptor expressed on myeloid cells-1 (sTREM-1) and miR-126 in peripheral blood were analyzed. In this study, 60 patients (study group) with postoperative lung infection in craniocerebral injury treated from January 2019 to December 2, 2021, and 60 patients without lung infection were selected as the control group. The study group received anti-infection treatment. The infection pathogen of the study group was tested, and the changes of sTREM-1 and miR-126 levels in the peripheral blood of the study and control groups were recorded to explore the diagnosis and predictive Value of prognostic death. 66 pathogens were detected, including 18 gram-positive bacteria, 42 gram-negative bacteria, and 6 fungi. The sTREM-1 level was higher than the control group, and the miR-126 level was lower than the control group. By ROC curve analysis, the diagnostic AUC values of both patients were 0.907 and 0.848, respectively (P< 0.05). Compared to those in the study group, patients had decreased sTREM-1 levels and increased miR-126 levels after treatment (P< 0.05). Compared with the survival group, patients in the death group had increased sTREM-1 levels and decreased miR-126 levels, and ROC curve analysis, the predicted AUC death values were 0.854 and 0.862, respectively. Gram-negative bacteria, with increased peripheral sTREM-1 levels and decreased miR-126 levels. The levels of sTREM-1 and miR-126 have specific diagnostic and prognostic Values for pulmonary infection after craniocerebral injury. However, the study's conclusions are drawn from a limited sample and short-term data, which might limit their broader applicability. Future studies with larger populations and longitudinal designs are required to confirm these findings and determine these biomarkers' robustness across different settings. Further research should also explore how these biomarkers influence patient outcomes in craniocerebral injuries.

Prognostic significance of serum secreted frizzled-related protein 5 in patients with acute aortic dissection

BackgroundSecreted frizzled-related protein 5 (SFRP5) is a novel adipokine that has been found to be closely associated with metabolic and cardiovascular diseases. We investigated serum SFRP5 levels during the acute phase and their predictive value for the prognosis of acute aortic dissection (AAD). MethodsIn total, 152 AAD patients and 164 controls were enrolled in this study. Serum SFRP5 levels were measured using an enzyme-linked immunosorbent assay (ELISA). AAD patients were divided into high-SFRP5 and low-SFRP5 groups based on the optimal cutoff value and followed up for prognosis. The primary endpoint was all-cause mortality, and the secondary endpoint focused on AAD-related events (including AAD-related mortality and unplanned reoperations). ResultsSerum SFRP5 levels were significantly higher in AAD patients than in non-AAD controls, regardless of whether they had Stanford type A or B AD. Multivariate logistic regression analysis revealed an independent association between SFRP5 and the presence of AAD (adjusted OR 1.267, 95 % CI 1.152–1.394; p < 0.001). The receiver operating characteristic curve demonstrated that the optimal cutoff value for SFRP5 to predict the presence of AAD was 10.26 ng/mL (AUC 0.7241, sensitivity 49.34 %, specificity 87.20 %). Notably, serum SFRP5 levels of patients in the death group were significantly higher than those in the survival group. Compared with patients in the low-SFRP5 group, those in the high-SFRP5 group exhibited a significantly increased risk of all-cause mortality (HR 9.540, 95 % CI 2.803–32.473; p < 0.001) and AAD-related events (HR 6.915, 95 % CI 2.361–20.254; p < 0.001) during the follow-up period. ConclusionSerum SFRP5 levels were significantly elevated in the acute phase of AAD, and high serum SFRP5 levels were independently associated with poor AAD prognosis. These results suggest that serum SFRP5 level during the acute phase may be an effective biomarker and therapeutic target for the prognosis of AAD.

Predictive performance of Metagenomic Next Generation Sequencing in early detection of post-liver transplantation infections

ObjectiveTo evaluate the predictive performance of metagenomic next-generation sequencing (mNGS) in identifying and predicting pulmonary infections following liver transplantation and to investigate its association with patient outcomes within the initial four-week post-transplantation period. MethodsWe retrospectively analyzed 41 liver transplant patients with suspected pulmonary infections from August 2022 to May 2023. Bronchoalveolar lavage fluid (BALF) samples were collected on the first postoperative day for metagenomic next generation sequencing (mNGS) and culture. The predictive capability of mNGS for subsequent infections was assessed by monitoring inflammatory biomarkers and comparing the detection rates with culture methods. Real-time Polymerase Chain Reaction (Rt-PCR) was used to monitor Human betaherpesvirus 5 (CMV) and Human parvovirus B19 (B19) weekly during a four-week postoperative period. Inflammatory biomarkers and blood coagulation function were evaluated on specific days throughout the first, third, fifth, and during four weeks following surgery. The study was conducted until August 2023 to evaluate the patients' prognostic survival outcome, classifying them into groups based on the mortality and survival. ResultsThe analysis included a total of 41 patients, comprising 32 males and 9 females, with an average age of 52 (47, 63) years. Within one week after liver transplantation, there were 7 cases of bacterial infections, 5 cases of fungal infections, 19 cases of mixed infections, 8 cases without any infection, and 2 cases with unidentified pathogen-associated infections. mNGS successfully predicted 39 (72 %) strains of pathogens, while culture-based methods only detected 28 (52 %) strains. Among the 8 patients diagnosed as non-infected, culture methods identified positive results in 4 cases (50 %), whereas mNGS yielded positive results in 7 cases (87.5 %). The detection rates of CMV and B19 by Rt-PCR within 4 weeks after liver transplantation were 61 % and 17 %, respectively (25/41, 7/41) among the patients. During the study period, a total of 9 patients succumbed while 32 patients survived. The death group and the survival group exhibited significant differences in CRP, HGB, and INR levels at specific monitoring time points. The proportion of CMV detection in blood was significantly higher in the death group compared to the surviving group. Elevated CRP level was identified as a prognostic risk factor. ConclusionsDespite the presence of false positives, mNGS still presents a potential advantage in predicting pulmonary infection pathogens following liver transplantation. Furthermore, the levels of CRP and CMV carrier status within four weeks post-surgery exhibit significant associations with patient survival and prognosis.

Cardiac Catheterization Post Congenital Cardiac Surgery: Analysis of Risk Factors for Mortality and Literature Review.

Background Diagnostic and interventional cardiac catheterization plays a significant role in the management of congenital heart defects with acceptable risks. Its role has also evolved in sick children but is associated with higher risks due to technical difficulties and co-morbidity factors. Some of the post-cardiac surgery children who show resistance to conventional management during the early postoperative period usually have residual defects or obstructions. Trans-catheter intervention (TCI) in such high-risk circumstances and relatively sick children is challenging, demands much expertise, and should be backed up by a competent multidisciplinary team. Some cases improve clinically, while others may require surgical or transcatheter re-intervention for a positive outcome. There is minimal data so far regarding the major complications after interventional cardiac catheterization during the immediate postoperative period after cardiac surgery.We analyzed multiple factors, including age, sex, weight, the initial diagnosis, and the time interval between surgery and TCI, to stratify the possible risks for mortality after TCI during the immediate postoperative period after cardiac surgery. Results Thirty-five patients fulfilled the inclusion criteria and underwent 43 interventional procedures. Five patients could not survive.Four had stent angioplasties on natural vasculature and one patient had in synthetic conduit. None of the mortality was related to the procedure.Multivariable risk factor analysis confirmed a moderate positive correlation coefficient (r) of 0.8017 between the variables. Still, it was not statistically significant if compared among subgroups or among the mortality and survival groups. Conclusion Interventional cardiac catheterization in sick children during the immediate postoperative period can be carried out without much-added risks in expert hands and under the supervision of a multi-disciplinary team.Though no conclusions could be drawn, our study adds to the limited existing data that could inspire others to perform such procedures on sick children. Moreover, the trend in our results indicated a large sample size could have identified a possible risk factor for mortality.

Analysis of early warning indicators of death in patients with severe fever with thrombocytopenia syndrome

BackgroundSince its discovery, severe fever with thrombocytopenia syndrome (SFTS) has been characterized by rapid progression and poor prognosis, and no specific treatment is available. The aim of this study was to investigate the early warning indicators of mortality in SFTS patients.MethodsThis is a retrospective cross-sectional study. The study subjects were patients who were admitted to the hospital with a confirmed diagnosis of SFTS from January 2023 to October 2023, and their clinical symptoms and signs at the time of admission, as well as the laboratory indexes of the first blood collection after admission were collected, grouped according to the prognosis, and statistically analyzed.ResultsA total of 141 patients were collected, of which 27 patients died and 114 patients were in the survival group. Through statistical analysis, patients with combined hemorrhagic manifestations, disturbance of consciousness, lymphopenia, elevated lipase, and prolonged thrombin time on admission were independent risk factors for patients’ death. By plotting the working characteristic curve of the subjects, as well as calculating the area under the curve, the results showed that the AUC of lymphopenia count was 0.670, 95% CI (0.563–0.776), P = 0.006; the AUC of elevated serum lipase index was 0.789, 95% CI (0.699–0.878), p < 0.001; the AUC of prolonged thrombin time was 0.749, 95% CI (0.645–0.854), p < 0.001.ConclusionPatients with hemorrhagic manifestations, disturbance of consciousness, lymphocyte reduction, elevated serum lipase, and prolonged thrombin time on admission are more worthy of the clinician’s attention, and require early and effective interventions to avoid further disease progression.

Clinical diagnostic value of metagenomic next-generation sequencing in patients with acute infection in emergency department

ObjectiveTo explore the value of metagenomic next-generation sequencing (mNGS) and culture in microbial diagnosis of patients with acute infection. MethodsWe retrospectively analyzed 206 specimens from 163 patients who were admitted to the emergency department of The First Affiliated Hospital of Sun Yat-sen University between July 2020, and July 2021. We evaluated the diagnostic efficacy of mNGS and in-hospital traditional culture. ResultsThe total positive rate of mNGS was significantly higher than that culture methods (71.4 % vs 40.8 %, p < 0.001), while the sensitivity and accuracy of mNGS were found to be 92.9 % and 88.2 % respectively. However, culture exhibited superior specificity with a value of 92.6 % compared to 75.9 % for mNGS. The detection efficiency of mNGS and culture for fungi was comparable, but mNGS showed superior performance for bacterial detection. In the analysis of sepsis samples, mNGS outperformed traditional culture methods in diagnosing various types of samples, especially for sputum and bronchoalveolar lavage fluid. Among the identified infections, bacterial infections were the most common single infection (37.5 %). Additionally, bacterial-fungal infections represented the most prevalent form of mixed infection (77.3 %). Candida albicans and Staphylococcus aureus were identified as the predominant pathogens in the survival and death groups, respectively. No significant differences in microbial diversity were observed. ConclusionCompared to culture methods, mNGS demonstrates superior positive rates, sensitivity, and accuracy in the rapid detection of acute infections, particularly in critically ill patients such as those with sepsis. This capability establishes a foundation for the swift and precise identification of pathogens, allowing for the analysis of clinical indicators and patient prognosis based on the extensive data generated from mNGS.

Elevated preoperative plasma D-dimer level is an independent prognostic factor for pediatric patients with Wilms tumor.

Elevated plasma D-dimer levels are an unfavorable prognostic indicator for various tumors. However, its predictive value for prognosis in pediatric patients with Wilms tumor (WT) remains unknown. We aimed to investigate the clinical and prognostic value of preoperative plasma D-dimer levels and other clinicopathological characteristics in patients with favorable histology WT (FHWT). The clinical data of 74 children with FHWT from January 2010 to January 2022 were retrospectively analyzed. The clinicopathologic characteristics, preoperative laboratory parameter results, including D-dimer level, and follow-up data were collected. Based on the postoperative recovery status, the patients were divided into tumor-free survival and disease progression groups. The risk factors affecting disease progression in pediatric patients with WT and the impact of plasma D-dimer levels on overall survival (OS) were evaluated. Over a median follow-up of 33 months (range: 2-145 months), 56 patients survived without progression. Relapses and metastases occurred in 18 patients, of which four survived and 14 died. Higher preoperative plasma D-dimer levels (>0.865) (Odds ratio [OR] = 7.240, 95% confidence interval (CI) = 1.276-33.272, P = 0.011) and tumor rupture (OR = 19.984, 95% CI = 1.182-338.013, P = 0.038) were independent prognostic factors for disease progression. Additionally, patients with elevated D-dimer levels demonstrated a worse 5-year OS than those with low D-dimer levels (Hazard ratio (HR) =4.278, 95% CI = 1.074-17.035, P = 0.039). Elevated D-dimer levels are a prognostic factor for a poorer outcome in pediatric patients with WT and are expected to become a clinical biomarker for predicting the prognosis of WT.
