Significant Difference In Survival Rate Research Articles

Comparative analysis of the expression of р16, PD-L1 in squamous cell carcinoma of the oropharynx and CUP syndrome

Introduction. metastases in the absence of a primary tumor (cancer of unknown primary (Cup) syndrome) are diagnosed in 2–4 % of malignant tumor cases. This pathology is characterized by early metastatic dissemination, weak response to conventional chemotherapy, and aggressive progression. The use of checkpoint inhibitors targeting programmed cell death protein 1 (pD-1) and its ligand (pD-L1) has shown good results in treatment of various cancers including oropharyngeal squamous cell carcinoma (OpSCC). In Cup syndrome, the effectiveness of checkpoint inhibitors is rarely investigated, and pD-L1 expression is often not measured.Aim. To compare the frequency of p16 and pD-L1 hyperexpression in OpSCC and Cup syndrome, and to analyze dependency of survival rates on the level of expression of p16, the most important prognostic marker.Materials and methods. The study included 121 patients (59 with OpSCC and 62 with Cup syndrome) who received medical treatment in the multidisciplinary medical Center “medical City” (Tyumen) and Chelyabinsk Oncological Center of Oncology and Nuclear medicine between 2019 and 2023. Immunohistochemical examination was performed using the vENTANA Benchmark gX with primary antibodies against pD-L1 (clone Sp263, uSA) and р16 (uS Biological, uSA). Statistical analysis of the data was performed using SpSS 26 software. Long-term treatment outcomes were evaluated using 1-, 3-, 5-year survival rates and median survival. Overall survival was analyzed using the kaplan-meier method. Statistical significance of the differences was evaluated using the Cox model.Results. The studied groups did not differ by sex (p = 0.472), age (р = 0.640), and N stage (р = 0.262). patient age in the whole population varied between 42 and 81 years (median age 61.89 ± 11.9 years; mean age 60.81 ± 9.8 years). pD-L1 expression rate was higher in Cup syndrome at 92 % compared to 73 % in OpSCC (statistically significant difference; р = 0.01). Analysis of the association of ORSCC and Cup syndrome with human papilloma virus showed statistically significant difference in p16 hyperexpression: patients with OpSCC had p16-positive status more frequently (53 % of cases) while patients with Cup syndrome mostly had p16-negative status (73 % of cases). mean life expectancy of patients with OpSCC and p16-positive status was 62.65 months (95 % confidence interval 54.98–70.31), minimal observation period was 12 months, maximal was 70 months. mean life expectancy of patients with Cup syndrome and positive p16 status was 66.22 months (95 % confidence interval 56.35–76.10), minimal observation period was 12 months, maximal was 70 months. No statistically significant differences in survival rates of patients with OpSCC and Cup syndrome were found (р = 0.999).Conclusion. The study showed higher pD-L1 expression in patients with Cup syndrome compared to patients with OpSCC: 92 and 73 %, respectively (р = 0.01). The obtained results highlight the importance of routine pD-L1 expression evaluation in patients with Cup syndrome. The frequency of p16 hyperexpression was higher in OpSCC compared to Cup syndrome: 53 % versus 27 % (р = 0.02) which agrees with the worldwide epidemiological data: among all malignant neoplasms of the head and neck, Hpv infection is most common in OpSCC. Therefore, it serves as an important sign of hidden oropharyngeal cancer in Cup syndrome.

Metal-Free Custom-Made Zirconia Implants-A Prospective 5-Year Follow-Up Single-Arm Clinical Trial.

Dental implants made of zirconia (ZrO2) are a potential alternative for titanium implants in dentistry because of their good biocompatibility, mechanical properties and excellent aesthetic results. However, solid long-term scientific data to prove clinical success of ZrO2 implants are scarce. The aim of this study was to describe and to examine the clinical performance of custom-made two-piece ZrO2 implants, to identify possible influencing factors: a) manipulation of the implant after placement and b) the occlusal scheme on the survival rate, and to evaluate the performance of the implant-supported crown. This follow-up study collected and examined the 5-year data to answer the main question: What are the survival and the success rates of custom-made ZrO2 implants in the maxillary premolar region after 5 years? Of the 31 included patients in this prospective 5-year follow-up single-arm clinical trial, 30 received a custom-made ZrO2 implant to replace a missing single maxillary premolar, which was subsequently restored with a lithium disilicate crown. Parameters regarding clinical performance, marginal bone-level (MBL) changes, and patient-related outcome measures (PROMs) were assessed preoperatively, at the baseline, as well as 1 and 5 years after crown placement. Chances of survival and success of the implant were calculated and displayed using Kaplan-Meier statistics. Kaplan-Meier survival analysis was also performed with stratification based on the variables "manipulation of the implant prior to impression taking" and "occlusal scheme" and compared using log-rank tests. Bone-level moderation in time was compared using a paired samples t-test. Patient's expectations and satisfaction after 5 years were compared as a measure of fulfilled expectations, using a Wilcoxon signed-rank test. Performance of the implant-supported crowns was evaluated using validated criteria. Survival and success probabilities after 5 years were, respectively, 75.8% (95% CI [60.0%; 91.0%]) and 71.0% (95% CI [54.0%; 88.0%]) for the custom-made ZV3 implants. No significant differences in survival rate were found after stratification on "manipulation of the implant" and on "occlusal scheme." Mean bone-level alteration between baseline and the first follow-up was +0.06 mm (95% CI [-0.23 mm; 0.12 mm]; SD = 0.42 mm) and between baseline and the second follow-up was +0.04 mm (95% CI [-0.35 mm; 0.26 mm]; SD = 0.54 mm). Patients' satisfaction for patients with implants still in function after 5 years was 91.7% (IQR = [90.5%-97.3%]), indicating satisfaction with the treatment. Pooled satisfaction in patients with successful implants after 5 years was significantly higher than patients' expressed expectations before treatment. None of the crowns failed, and no interventions were required. Survival rate of these particular ZV3 implants in our study was lower than expected and clinically not acceptable. Hence, ZV3 implant placement as applied in this study cannot be recommended for clinical practice. Further research on the different appearances of mechanical failure in ZrO2 implants would be highly recommended before a larger prospective randomized clinical trial is conducted to evaluate treatment with custom-made ZrO2 dental implants.

Positive effects of a mixture of fish oil and soybean oil as a dietary lipid source on the ovarian development and health of female giant river prawn, Macrobrachium rosenbergii broodstock

Lipids are key nutrients that affect the development of the ovary in aquatic animals. This study aimed to investigate the effects of different lipid sources on the ovarian development and health of Macrobrachium rosenbergii broodstock. The M. rosenbergii broodstock, with an initial body weight of 8.07±0.74 g, were fed diets containing 5 % fish oil (FO), soya bean oil (SO), rapeseed oil (RO), coconut oil (CO), and a 1:1 mixture of fish oil and soybean oil (MO) as lipid sources for a period of 56 days. The results indicated that there were no significant differences in survival rate (SR) and hepatopancreatic index (HSI) among the different groups (P > 0.05). However, the specific growth rate (SGR) and gonadosomatic index (GSI) in the MO group were significantly higher than other groups (P < 0.05). Additionally, fatty acid levels in diets directly influenced the fatty acid composition of prawn hepatopancreas, showing a similar trend to that observed in the diet itself. Furthermore, compared to the other trial groups, haemolymph levels of 17-β estradiol (E2) and progesterone (PROG) were significantly increased in the MO group (P < 0.05). The ovarian section also exhibited better histomorphology and larger oocyte diameter in this group. Moreover, total antioxidant capacity was significantly increased in the MO group (P < 0.05). Saturated fatty acids in RO and CO groups could promote the expression of lipid synthesis-related genes fatty acid synthase (fas) and acetyl-CoA carboxylase (acc), concurrently suppressing the expression of lipid catabolism-related genes acyl-CoA oxidase-1 (acox-1) and AMP-activated protein kinase alpha (ampkα) (P < 0.05). Conversely, polyunsaturated fatty acids in the MO group significantly up-regulated the expression levels of fatty acid binding protein-3 (fabp-3) and peroxisome proliferator-activated receptor gamma (pparγ) (P < 0.05). Based on the findings of hepatopancreatic tissue structure, it was determined that the use of a single vegetable oil resulted in some damage to the hepatopancreatic tissue structure of M. rosenbergii broodstock, leading to increased oxidative stress. In conclusion, it is recommended that a 1:1 mixture of fish oil and soybean oil be used as a dietary lipid source to effectively meet the nutritional requirements during the ovarian development period of M. rosenbergii broodstock. This combination also enhances antioxidant properties, promotes the synthesis of haemolymph steroid hormones and lipid metabolism in female prawns, thereby facilitating ovarian development and overall health of M. rosenbergii broodstock.

Exploring the Dual Benefits of Fermented and Non-Fermented Garlic Powder on Growth, Antioxidative Capacity, Immune Responses, and Histology in Gray Mullet (Liza ramada)

This study investigated the effects of dietary garlic powder and fermented garlic powder supplementation at 1% and 2% levels on growth performance, digestive tract efficacy, blood biochemistry, immunity, and antioxidant status of Liza ramada (n = 225 fish; 86.00 ± 0.42 g) over a 60-day period. Fish fed diets supplemented with both forms of garlic at both levels exhibited significantly improved final body weight, weight gain, specific growth rate, and feed conversion ratio compared to the control group. Digestive enzyme activities (amylase, lipase, and protease) were significantly enhanced in all supplemented groups. Blood biochemical analysis revealed reduced glucose levels and increased total protein in garlic-supplemented groups, with no adverse effects on liver or kidney function markers. Immune parameters, including lysozyme activity, bactericidal activity against Streptococcus agalactiae, alternative complement pathway (ACP), and respiratory burst (NBT), were significantly enhanced in garlic-supplemented groups, with fermented garlic showing more pronounced effects. Antioxidant enzyme activities (SOD, CAT, and GPx) were also significantly increased in all supplemented groups, particularly in those fed fermented garlic. No significant differences in survival rates were observed among treatments. The results suggest that both garlic powder and fermented garlic powder supplementation, especially at the 2% level, can effectively improve growth, feed utilization, immune function, and antioxidant status in L. ramada. Fermented garlic generally demonstrated superior effects, indicating its potential as a beneficial feed additive in aquaculture. Based on these findings, it is recommended to incorporate fermented garlic powder at a 2% level in L. ramada diets to optimize growth performance and health status. Further research is warranted to investigate the long-term effects and cost-effectiveness of this supplementation strategy in commercial aquaculture settings.

Effects of high α-linolenic acid transgenic rapeseed oil diet on growth performance, fat deposition, flesh quality, antioxidant capacity, and immunity of juvenile largemouth bass (Micropterus salmoides).

Omega-3 long-chain polyunsaturated fatty acid (n-3 LC-PUFA) increases in aquatic products contributes to improving meat quality, thereby positively impacting human health. Different from marine fish which primarily obtain n-3 LC-PUFAs directly from zooplankton and algae, freshwater fish mainly utilize dietary linolenic acid (ALA) as a substrate to synthesize n-3 LC-PUFAs. Our team has successfully created a transgenic rapeseed oil (TRO) with high ALA content. Therefore, we here assessed the impacts of four different diets (LR, low-fat rapeseed oil (RO) diet; HR, high-fat RO diet; LTR, low-fat TRO diet; HTR, high-fat TRO diet) on growth performance, lipid accumulation, fatty acid composition, antioxidant capacity, immunity and serum biochemical indexes of juvenile largemouth bass (Micropterus salmoides), an economically valuable freshwater fish. The results showed no significant difference in survival rate among the four dietary groups. No significant differences in body weight gain and final weight were found between the LR and LTR groups, as well as between HR and HTR groups. No matter if it was a high-fat or low-fat diet, compared with the RO diet, TRO diets significantly increased the content of n-3 LC-PUFA, improved meat quality, effectively alleviated lipid accumulation in livers and muscles of juvenile largemouth bass. In addition, using high-fat diets, TRO diet improved the antioxidant capacity and immune ability of juvenile largemouth bass, thereby promoting the overall health of fish. This study provides novel insights for fish feed formulation optimization from the perspective of genetically modified feed ingredients, and high-quality aquatic products for human consumption.

Comparison of Postoperative Outcomes and Long-Term Survival Rates between Patients Who Underwent Robotic and Laparoscopic Complete Mesocolic Excision for Right-Sided Colon Cancer.

Introduction: Right colon cancer often requires surgical intervention, and complete mesocolic excision (CME) has emerged as a standard procedure. The study aims to evaluate and compare the safety and efficacy of robotic and laparoscopic CME for patients with right colon cancer and 5-year survival rates examined to determine the outcomes. Materials and Methods: Patients who underwent CME for right-sided colon cancer between 2014 and 2021 were included in this study. Group differences of age, body mass index, operation time, bleeding amount, total harvested lymph nodes, and postoperative stay were analyzed by the Mann-Whitney U test. Group differences of sex, American Society of Anesthesiology, and tumor, node, and metastasis stage were analyzed by the Chi-squared test. Disease-free and overall survival were assessed using Kaplan-Meier curves with the log-rank Mantel-Cox test. Results: From 109 patients, 74 of them were 1:1 propensity score matched and used for analysis. Total harvested lymph node (P ≤ .001) and estimated blood loss (P = .031) were found to be statistically significant between the groups. We found no statistically significant difference between the groups in terms of disease-free and overall survival (P = .27, .86, respectively), and the mortality rate was 9.17%, with no deaths directly attributed to the surgery. Conclusions: Study shows that minimally invasive surgery is a feasible option for CME in right colon cancers, with acceptable overall survival rates. Although the robotic approach has a higher lymph node yield, there was no significant difference in survival rates. Further randomized trials are needed to determine the clinical significance of both approaches.

Establishment and evaluation of rat models of parastomal hernia.

Parastomal hernia poses a challenging problem in the field of hernia surgery. The high incidence and recurrence rates of parastomal hernia necessitate surgeons to enhance surgical techniques and repair materials. This study aimed to develop a rat model of parastomal hernia by inducing various types of defects on the abdominal wall with colostomy. This established method has potential for future studies on parastomal hernia. In this study, 32 male rats were included and randomly divided into four groups: the oblique abdominis excision (OE), oblique abdominis dissection (OD), rectus abdominis excision (RE), and rectus abdominis dissection (RD) groups. In each group, colostomy was performed and an abdominal wall defect was induced. The rats were observed for 28days following surgery. The survival rate, body weight, parastomal hernia model scores, abdominal wall adhesion and inflammation, and collagen level in the hernial sac were compared. No significant differences in survival rate and weight were observed among the four groups. The parastomal hernia model scores in the RE and RD groups were significantly higher than those in the OE and OD groups. The ratio of collagen I/III in the RE and RD groups was significantly lower than that in the OE and OD groups. Adhesion and inflammation levels were lower in the RE group than in the RD group. Based on a comprehensive comparison of the findings, RE with colostomy emerged as the optimal approach for establishing parastomal hernia models in rats.

Impacts of participation in surgical clinical trial on safety and survival outcomes in patients with right-sided colon cancer

Objective: To explore the impact on safety and prognosis in patients with right-sided colon cancer participating in surgical clinical research. Methods: This retrospective cohort study utilized data from a randomized controlled trial (RELARC study) conducted by the colorectal surgery group at Peking Union Medical College Hospital in which laparoscopic complete mesocolic excision (CME) was compared with D2 radical resection for the management of right-sided colon cancer. The eligibility criteria were age 18-75 years, biopsy-proven colon adenocarcinoma, tumor located between the cecum and right 1/3 of the transverse colon, enhanced chest, abdomen, and pelvic CT scans suggesting tumor stage T2-T4N0M0 or TanyN+ M0, and having undergone radical surgical treatment from January 2016 to December 2019. Exclusion factors included multiple primary colorectal cancers, preoperative stage T1N0 or enlarged central lymph nodes, tumor involving surrounding organs requiring their resection, definite distant metastasis or otherwise unable to undergo R0 resection, history of any other malignant tumors within previous 5 years, intestinal obstruction, perforation, or gastrointestinal bleeding requiring emergency surgery, and assessed as unsuitable for laparoscopic surgery. Patients who had participated in the RELARC study were included in the RELARC group, whereas those who met the inclusion criteria but refused to participate in the RELAEC study were included in the control group. The main indicators studied were the patient's baseline data, surgery and perioperative conditions, pathological characteristics, adjuvant treatment, and postoperative follow-up (including average frequency of follow-up within the first 3 years) and survival (including 3-year disease-free survival rate (DFS) and 3-year overall survival rate (OS). Differences in these indicators between the RELARC and control groups were compared. Results: The study cohort comprised 290 patients, 173 in the RELARC group (RELARC-CME group, 82; RELARC-D2 group, 91) and 117 in the control group (CME control group, 72; D2 control group, 45). There was a significantly higher proportion of overweight patients (BMI ≥24 kg/m2) in the RELARC-CME than in the CME control group (67.1% [55/82] vs. 33.3% [24/72], χ2=17.469, P<0.001). There were no other statistically significant differences in baseline characteristics (all P>0.05). No significant disparities were found between the CME and D2 groups in terms of operation duration, intraoperative blood loss, rate of conversion to open surgery, combined organ resection, intraoperative blood transfusion, or intraoperative complications (all P>0.05). There was a trend toward Clavien-Dindo grade II or higher postoperative complications in the RELARC-CME group (24.4% [20/82]) than in the CME control group (18.1% [13/72]); however, this difference was not statistically significant (χ2=0.914, P=0.339). Similarly, the difference in this rate did not differ significantly between the RELARC-D2 group (25.3% [23/91]) and D2 control group (24.4% [11/45], χ2=0.011, P=0.916). The median duration of postoperative follow-up was significantly shorter in the RELARC groups than in the corresponding control groups. Specifically, the median duration of follow-up was 4.5 (4.5, 4.5) months in the RELARC-CME and 7.2 (6.0, 9.0) months in the CME control group (Z=-10.608, P<0.001). Similarly, the median duration of follow-up was 4.5 (4.5, 4.5) months in the RELARC-D2 group as opposed to 8.3 (6.6, 9.0) months in the D2 control group (Z=-10.595, P<0.001). The 3-year DFS rate (91.5%) and OS rate (96.3%) tended to be higher in the RELARC-CME group than in the CME control group (84.7% and 90.3%, respectively). The 3-year DFS rate (87.9%) and OS rate (96.7%) tended to be higher in the RELARC-D2 group than in the D2 control group (81.8% and 88.6%, respectively); however, these differences were not statistically significant (all P>0.05). Subgroup analysis according to pathological stage revealed that patients in the RELARC-D2 group with pN0 stage achieved a significantly superior 3-year OS rate than did those in the D2 control group (100% vs. 88.9%, P=0.008). We identified no statistically significant differences in survival rates between the remaining subgroups (all P>0.05). Conclusions: A high-quality surgical clinical trial with close follow-up can achieve perioperative safety and a trend toward improved survival outcomes.

Mechanistic Regulation of Epidermal Growth Factor and Hormonal Receptors by Kinase Inhibitors and Organofluorines in Breast Cancer Therapy.

Differential expression patterns of growth factor (EGFR, HER-2) and hormonal (ER, PR) receptors in breast cancer (BC) remain crucial for evaluating and tailoring therapeutic interventions. This study investigates differential expression profiles of hormonal and growth factor receptors in BC patients and across age groups, major subclasses, disease stages and tumor histology and survival rates, the efficacy of emerging clinical trial drugs (Dabrafenib and Palbociclib) and elucidating their molecular interaction mechanisms for efficient therapeutic strategies. Gene and protein expression analysis in the normal vs BC and across age groups and major subclasses reveals divergent patterns as EGFR and HER-2 levels are reduced in tumors versus normal tissue, while ER and PR levels are higher, particularly in luminal subtypes. However, there was no significant difference in survival rates among high and low/medium expression levels of EGFR and PR receptors. Conversely, patients with high HER-2 and ER expression exhibited poorer survival rates compared to low or medium expression levels. The in vitro findings indicate that Dabrafenib exhibits greater effectiveness than Palbociclib in suppressing various BC cells such as MCF-7 (Luminal), MDA-MB-231 (Triple-Negative), SKBR-3 (HER-2 + ) proliferation, promoting cell death, (IC50 of Dab < Pal) at 24 and 48 h, ROS production, and reduced ER and PR, elevated HER-2 with no change in EGFR expression. Molecular simulation studies revealed Dabrafenib's thermodynamically stable interactions (ΔG), tighter binding, and less structural deviation in the order EGFR > HER-2 > ER > PR as compared to Palbociclib (HER-2 > ER > PR = EGFR). These results indicate that Dabrafenib, compared to Palbociclib, more effectively regulates breast cancer cell proliferation through specific interactions with hormonal and growth factor receptors towards a repurposing approach.

Effect of Amorphous Halomonas-PHB on Growth, Body Composition, Immune-Related Gene Expression and Vibrio anguillarum Resistance of Hybrid Grouper (Epinephelus fuscoguttatus ♀ × E. lanceolatu ♂) Juveniles.

Poly-β-hydroxybutyrate (PHB) is a bacterial metabolite produced by bacteria such as Halomonas sp. that serves as a carbon and energy storage compound for bacteria under nutrient-limited conditions. Two experiments were conducted to investigate the effects of dietary supplementation with Halomonas-PHB on hybrid grouper (Epinephelus fuscoguttatus ♀ × E. lanceolatu ♂). In experiment I, juvenile groupers were fed basal diets supplemented with 3% Halomonas-PHB (3% HM-PHB) containing 1.4% PHB and 3% Halomonas (3% HM) without PHB, as well as a control diet, for seven weeks. The results showed no significant difference in survival rate, weight gain, and crude fat content between the 3% HM-PHB group and the control group; however, the crude protein of the 3% HM-PHB group was significantly lower than that of the control group. Furthermore, supplementation with 3% HM-PHB increased the fatty acids content in fish muscles, including long-chain unsaturated fatty acids C18:1n9, EPA, and DHA. In experiment II, groupers were fed a basal diet supplemented with 6.5% Halomonas-PHB (6.5% HM-PHB) containing 3% PHB and 6.5% Halomonas (6.5% HM) containing no PHB, as well as a basal diet (Control). After seven weeks of rearing, the fish were challenged with Vibrio anguillarum for 48 h. Although no significant difference in survival rate and growth was observed among different groups, the dietary supplement of 6.5% Halomonas-PHB improved the survival rate of V. anguillarum challenged grouper and significantly increased the gene expressions of catalase (CAT) and superoxide dismutase (SOD) in blood, interleukin 1 (IL1) and interleukin 10 (IL10) in the liver, spleen, head kidney, and blood (p < 0.05). In conclusion, dietary supplementation of Halomonas-PHB had no significantly positive effect on fish growth performance but increased the content of fatty acids, including long-chain unsaturated fatty acids C18:1n9, EPA, and DHA in fish muscle; it also improved the V. anguillarum resistance, possibly through increasing immune-related gene expression in different tissues and organs. Our findings offer compelling evidence that Halomonas-PHB can be utilized as a feed additive in intensive grouper farming to enhance the groupers' resistance to Vibrio.

Comparison of Prognostic Performance of 8th and 7th Edition of AJCC Staging System for Patients With Gallbladder Cancer Undergoing Curative Intent Surgery.

We compared the predictive performance of the 7th and 8th editions of the AJCC staging systems in stratifying disease-related survival outcomes in patients with GBC undergoing curative intent surgery. Patients that underwent curative intent surgery for GBC at our institution (2014 and 2021) were included in the study. Various clinico-pathological data were extracted to perform Kaplan-Meier survival analysis. A total of 240 patients were included in the study. Both, TNM-7, and TNM-8 staging systems can stratify patients into stages with statistically significant differences in disease-free and overall survival. Survival rates drop with stage progression. Using TNM-8, 8/240 (3.33%) patients were upstaged from Stage IIIB (TNM-7) to IVB (TNM-8) and 12/240 (5%) were down-staged from Stage IVB(TNM-7) to IIIB(TNM-8). Survival curves of the re-classified patients matched those of the corresponding TNM-8 stage. Additionally, there was statistically significant difference in their survival (p < 0.001) compared to their corresponding TNM-7 stage. There was no statistically significant difference in survival rates between stages IIA, IIB (TNM-8), and stage II (TNM-7). However, stage IIA had a slightly better survival than stage IIB. Though both TNM-7 and TNM-8 are useful for stratifying patients with GBC, TNM-8 has a better prognostic performance than TNM-7.

Inflammatory indexes and anemia in chronic kidney disease: correlation and survival analysis of the National Health and Nutrition Examination Survey 2005–2018

Background There is currently no research on the correlation between novel inflammatory indexes systemic immune-inflammation index (SII), neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), and the risk of anemia in chronic kidney disease (CKD) population, as well as survival analysis in CKD with anemia. Methods This investigation encompassed 4444 adult subjects out of the National Health and Nutrition Examination Survey (NHANES) between 2005 and 2018. The study utilized multi-variable logistic regression to assess the relationship between SII, NLR, PLR, and anemia risk occurrence in CKD population. Survival differences in CKD patients with anemia, based on varying levels of SII, NLR, and PLR were evaluated employing Kaplan–Meier and Cox proportional hazards models. Results The adjusted logistic regression model demonstrates that SII, NLR, and PLR are associated with the risk of anemia occurrence in CKD population. Kaplan–Meier’s analysis reveals significant differences in survival rates among CKD patients with anemia stratified by NLR levels. The adjusted Cox proportional hazards model shows that the higher NLR group has a 30% elevated risk of all-cause mortality contrasted with lower group (hazard ratio, HR: 1.30, confidence interval (CI) [1.01, 1.66], p value <.04). Restricted cubic spline (RCS) demonstrates no nonlinear relationship between NLR and all-cause mortality. Lastly, sub-cohort analysis indicates that in populations with diabetes, hypertension, and hyperuricemia, NLR levels have a greater impact on all-cause mortality. Conclusions Controlling inflammation may reduce the occurrence of anemia in CKD populations, with NLR serving to be a potential prognostic indicator for survival results within CKD patients suffering from co-morbid anemia.

The influence of genetic similarity, peroxidase activity and ascorbic acid content in the components of pumpkin crop grafts on their survival rate

Grafting of vegetable crops is widely used in industrial vegetable growing in Asia and Western Europe. However, the influence of the genetic relationship of the scion and rootstock, the activity of peroxidase and the content of ascorbic acid in the components of the graft during inosculation period on graft survival has been poorly studied. The objects of the research are nine species of the pumpkin family (Cucurbitaceae). The polymorphism of 11 taxa was studied based on ISSR-PCR of genomic DNA. The record of survival rate of scion-rootstock combinations was conducted on the 10-th day. The activity of peroxidase was determined by the spectrophotometric method, the content of ascorbic acid was determined by Murri. Significant differences in survival rate were noted when grafting momordica into pumpkin rootstock variants: large-fruited (94.6 %) and nutmeg (67.1 %). In experiments with watermelon, melon and trichosanthes, the influence of the type of rootstock on the viability of the graft was not revealed. According to the ISSR spectra, the taxa were divided into two clusters; interspecific groupings of each clade were supported by average bootstrap values (from 26 to 100 %). A medium effect (r = 0.36) of the degree of genetic similarity of the scion with the rootstock on the survival rate of watermelon and a weak effect on the survival rate of melon, momordica and trichosanthes were revealed. The activity of peroxidase and the content of ascorbic acid in the grafting components in different scionrootstock combinations had a weak and moderate effect on plant survival, respectively. The survival rate of trichosanthes on various types of rootstocks strongly depended on the content of ascorbic acid (r = 0.7). Genetic relatedness, peroxidase activity, and ascorbic acid content had a weak or moderate effect on the survival rate of plants in scion-rootstock combinations.

Survival characteristics of Wilms Tumor, a reference developed from a longitudinal cohort study

BackgroundWilms tumor (WT) survival has been affected by the evolution in clinical and biological prognostic factors. Significant differences in survival rates indicate the need for further efforts to reduce these disparities. This study aims to evaluate the clinicopathological data impact on survival among patients after Wilm's diagnosis.MethodsThe study utilized the SEERStat Database to identify Wilms tumor patients, applying SEERStat software version 8.3.9.2 for data extraction. Selection criteria involved specific codes based on the International Classification of Diseases for Oncology (ICDO-3), excluding cases with unknown SEER stage, incomplete survival data, unknown size, or lymph node status. Statistical analyses, including Kaplan–Meier estimates and Cox regression models, were conducted using R software version 3.5. Standardized mortality ratios (SMR) were computed with SEER*Stat software, and relative and conditional survival analyses were performed to evaluate long-term survival outcomes.ResultsOf 2273 patients diagnosed with Wilms tumor, (1219 patients, 53.6% were females with an average age group of 3–8 years (50.2%). The overall mean survival after five years of diagnosis was 93.6% (2.6–94.7), and the overall mean survival rate was 92.5% (91.3–93.8) after ten years of diagnosis. Renal cancers were identified as the leading cause of death (77.3%), followed by nonrenal cancers (11%) and noncancer causes (11%). Additionally, robust relative survival rates of 98.10%, 92.80%, and 91.3% at one, five, and ten years, respectively, were observed, with corresponding five-year conditional survival rates indicating an increasing likelihood of survival with each additional year post-diagnosis. Univariate Cox regression identified significant prognostic factors: superior CSS for patients below 3 years (cHR 0.48) and poorer CSS for those older than 15 years (cHR 2.72), distant spread (cHR 10.24), regional spread (cHR 3.09), and unknown stage (cHR 4.97). In the multivariate model, age was not a significant predictor, but distant spread (aHR 9.22), regional spread (aHR 2.84), and unknown stage (aHR 4.98) were associated with worse CSS compared to localized tumors.ConclusionThis study delving into WT survival dynamics reveals a multifaceted landscape influenced by clinicopathological variables. This comprehensive understanding emphasizes the imperative for ongoing research and personalized interventions to refine survival rates and address nuanced challenges across age, stage, and tumor spread in WT patients.

Responses of oscar (Astronotus ocellatus) to different temperatures and its interaction with early mild stress

Non-optimum temperature results in stress in fish through different biological and physiological processes. This study investigated how early mild stress (EMS) and temperature can influence growth, hematology, blood biochemistry, immunological response, antioxidant system, liver enzymes, and stress response of juvenile oscar (Astronotus ocellatus; 8.02 ± 0.81 g) before and after acute confinement stress (AC stress). Eight experimental treatments were 17D (farmed at 17 °C), 22D (farmed at 22 °C), 27D (farmed at 27 °C), 32D (farmed at 32 °C), 17DES (farmed at 17 °C and EMS), 22DES (farmed at 22 °C and EMS), 27DES (farmed at 27 °C and EMS), and 32DES (farmed at 32 °C and EMS). At the end of the experiment (nine weeks), there was no significant difference in survival rate, feed conversion ratio, body composition, and survival rate after the AC stress (ten weeks). The growth rates in the 17 and 32 °C groups were lower than others, showing the negative effect of temperature being too high or too low. After nine weeks, fish farmed at 32 °C had the highest hematological parameters (hematocrit, hemoglobin, red blood cells, and blood performance) and liver enzymes (lactate dehydrogenase, alanine transaminase, and aspartate transaminase). This group also has the lowest lysozyme, alternative complement pathway (ACH50), immunoglobulin, complement C3, complement C4, superoxide dismutase, and glutathione peroxidase. The EMS did not positively or negatively affect fish physiology in this study. In conclusion, the optimum temperature for oscar to achieve the best growth performance, immune response, and health status is 22–27 °C.

Significance of Systemic Scleroderma-Specific Autoantibodies in Idiopathic Interstitial Pneumonia.

Objective Patients with idiopathic interstitial pneumonia (IIP) often test positive for systemic scleroderma-specific autoantibodies (SSc-Ab), even if they do not meet the diagnostic criteria for systemic scleroderma (SSc). However, the significance of SSc-Ab in IIP is unknown. Methods We retrospectively studied the medical records of all patients suspected of interstitial lung disease (ILD) who visited our center between January 2016 and December 2021. We evaluated the association between SSc-Ab subtypes and clinical characteristics, prognosis, and incidence of acute exacerbation (AE) of IIP. Among 571 patients suspected of having IIP and SSc-Ab measured, we excluded cases with clear causes of ILD or those diagnosed with other diseases and analyzed 386 cases diagnosed as IIP. Results Among 386 IIP patients, 48 were SSc-Ab positive (platelet-derived growth factor receptor (PDGFR) in 0, Th/To in 10, anti-nucleolar organizer region 90 antibodies (NOR90) in 12, fibrillarin in five, RP155 in 14, RP11 in three, CENP A in seven, CENP B in 10, and Scl-70 in six). There was no significant difference in survival rate or incidence of AE between patients with or without SSc-Ab. Multivariate logistic regression analysis showed that age and malignancy were significant risk factors for death, whereas age, male sex, and anti-fibrillarin antibodies were significant risk factors for AE of IIP. Conclusion None of the SSc-Abs were associated with the risk of mortality, and anti-fibrillarin antibodies, along with age and male sex may contribute to the risk of AE of IIP, predicting severe lung involvement and warranting multidisciplinary treatment and careful follow-up.

Genomic Selection of Large Yellow Croaker (Larimichthys crocea) with a High Plant Protein Diet Enhances the Growth Performance of Offspring.

Fishmeal is over-represented in the diets of large yellow croaker (Larimichthys crocea), and this farming mode, which relies heavily on fishmeal, is highly susceptible to the price of fishmeal and is unsustainable. Therefore, more and more studies on the large yellow croaker tend to replace fishmeal with land-based animal or plant proteins, but few studies have considered it from the genomic selection. In this study, we evaluated the survival rate (SR), final body weight (FBW), body weight gain (BWG), weight gain rate (WGR), and specific growth rate (SGR) of the large yellow croaker GS7 strain, which was obtained through genomic selection for tolerance to plant proteins and analyzed the differences in plant protein utilization between the GS7 strain and unselected commercial large yellow croaker (control group). The results of separate feeding for 60days showed that although there was no significant difference in SR between the control and GS7 strains (P > 0.05), the BWG, WGR, and SGR of the control were significantly lower (P < 0.05) than those of the GS7 group. Results of mixed feeding after PIT marking showed that compared to the control fish, the GS7 strain had significantly higher BWG, WGR, and SGR (P < 0.0001). To make the experimental results more precise, we compared fishes with equivalent initial body weight (IBW) in the GS7 strain and the control group. The final fish body weight (FBW) of Ctrl-2 (IBW 300-399g) and Ctrl-4 (IBW 500-599g) was significantly lower than those of the corresponding GS7-2 and GS7-4 (P < 0.05), while the FBW of Ctrl-1 (IBW 200-299g) and Ctrl-3 (IBW 400-499g) was much significantly lower than the corresponding GS7-1 and GS7-3 (P < 0.01). The BWG, WGR, and SGR of Ctrl-1 and Ctrl-4 were more significantly lower than those of the corresponding GS7-1 and GS7-4 (P < 0.01), while the BWG, WGR, and SGR of Ctrl-2 and Ctrl-3 were more significantly different from the corresponding GS7-2 and GS7-3 (P < 0.0001). Our results seem to point toward the same conclusion that the GS7 strain is better adapted to high plant protein diets than the unselected commercial large yellow croaker. These results will provide a reference for the low-fishmeal culture industry of large yellow croakers and the selection and breeding of strains tolerant to a high percentage of plant proteins in other marine fishes.

The role of radiotherapy in the treatment of sinonasal undifferentiated carcinoma: A population-based analysis.

Sinonasal undifferentiated carcinoma (SNUC) is a rare, aggressive disease with ambiguous management and poor prognosis. This study aimed to evaluate the role of radiation therapy (RT) and explore the optimal treatment sequence. Retrospective analysis of survival trends of 410 SNUC patients between 1973 and 2015. The 5-year cancer-specific survival (CSS) rate (45.1%) and overall survival (OS) rates (38.1%) were reported in the 84-month median follow-up. Radiotherapy was a prognosticator for improving CSS (hazard ratio [HR] = 0.425, 95% confidence interval [CI]: 0.299-0.603, p = 0.000) and OS (HR = 0.415, 95% CI: 0.303-0.570, p = 0.000), either with surgery (p = 0.000) or without surgery (p = 0.000). However, in a combined therapy of surgery and RT, preoperative and postoperative RT (5-year OS rates were 47.1% and 45.6%, respectively, p = 0.486) were not significantly different. Radiotherapy plays a key role in improving SNUC survival rates. No significant difference in survival rates was observed in preoperative and postoperative RT treatment.

Gene signatures of copper metabolism related genes may predict prognosis and immunity status in Ewing's sarcoma.

Cuproptosis is copper-induced cell death. Copper metabolism related genes (CMRGs) were demonstrated that used to assess the prognosis out of tumors. In the study, CMRGs were tested for their effect on TME cell infiltration in Ewing's sarcoma (ES). The GEO and ICGC databases provided the mRNA expression profiles and clinical features for downloading. In the GSE17674 dataset, 22prognostic-related copper metabolism related genes (PR-CMRGs) was identified by using univariate regression analysis. Subsequently, in order to compare the survival rates of groups with high and low expression of these PR-CMRGs,Kaplan-Meier analysis was implemented. Additionally, correlations among them were examined. The study employed functional enrichment analysis to investigate probable underlying pathways, while GSVA was applied to evaluate enriched pathways in the ES (Expression Set). Through an unsupervised clustering algorithm, samples were classified into two clusters, revealing significant differences in survival rates and levels of immune infiltration. Using Lasso and step regression methods, five genes (TFRC, SORD, SLC11A2, FKBP4, and AANAT) were selected as risk signatures. According to the Kaplan-Meier survival analysis, the high-risk group had considerably lower survival rates than the low-risk group(p=6.013e-09). The area under the curve (AUC) values for the receiver operating characteristic (ROC) curve were 0.876, 0.883, and 0.979 for 1, 3, and 5 years, respectively. The risk model was further validated in additional datasets, namely GSE63155, GSE63156, and the ICGC datasets. To aid in outcome prediction, a nomogram was developed that incorporated risk levels and clinical features. This nomogram's performance was effectively validated through calibration curves.Additionally, the study evaluated the variations in immune infiltration across different risk groups, as well as high-expression and low-expression groups. Importantly, several drugs were identified that displayed sensitivity, offering potential therapeutic options for ES. The findings above strongly indicate that CMRGs play crucial roles in predicting prognosis and immune status in ES.
