Diagnostic value of contrast-enhanced ultrasound in judging the survival of graft after heteroautoplasty for secondary hyperparathyroidism.

Secondary hyperparathyroidism (SHPT) is one of the common complications of end-stage renal disease-uremia, and is mainly manifested as parathyroid hyperplasia and abnormal secretion of parathyroid hormone (PTH). To investigate the value and advantages of contrast-enhanced ultrasound (CEUS) in evaluating the survival of autografts after parathyroidectomy + parathyroid autotransplantation. In this study, 125 patients with renal failure due to polycystic kidney disease, chronic nephritis, diabetic nephropathy, lupus nephritis, and atherosclerotic nephropathy were enrolled as the participants and each of them had 4 secondary hyperactive parathyroid glands and underwent parathyroid autotransplantation. One parathyroid gland was taken from each patient and equally divided into 4 parts and placed in the subcutaneous fat of one forearm for transplantation. CEUS was performed 14 days after the transplantation to observe the micro blood supply of the graft and assess the survival and secretory function of the transplanted parathyroid. The grafts were divided into the partial survival group and the total survival group based on the enhancement characteristics. The survival of the grafts was determined by comparing the parathyroid hormone level in bilateral elbow cephalic veins 1 month after surgery. Among the 125 patients, 112 had linear or punctate enhancement of 2-4 parathyroid glands 14 days after surgery, and 13 patients had linear or punctate enhancement of 0-1 parathyroid gland. There were statistically significant differences in the perfusion pattern, enhancement uniformity, and parathyroid hormone levels in the cephalic veins at the elbow on both the graft and non-graft sides among all groups (P< 0.05). Compared to the detection of the difference in the parathyroid hormone level in the cephalic vein of bilateral elbows 1 month after surgery, CEUS can reflect the parathyroid survival after transplantation more quickly and accurately 2weeks later, and provide a more rapid and agile non-invasive clinical diagnosis method.

Evaluation of the probiotic, technological, safety attributes, and GABA-producing capacity of microorganisms isolated from Iranian milk kefir beverages.

Kefir beverage has beneficial microorganisms that have health-giving properties; therefore, they have a good potential to be probiotic. This study evaluated the probiotic potential, technological, and safety characteristics of Enterococcus faecalis, Lactococcus lactis, and Pichia fermentans isolated from traditional kefir beverages. First, isolates were evaluated in terms of resistance to acid, alkali, bile salts, trypsin, and pepsin of the gastrointestinal tract. The auto-aggregation and co-aggregation ability of isolates were measured using spectrophotometry. Antimicrobial activities were assayed against important food-borne pathogens using the agar well diffusion method. Moreover, gamma-aminobutyric acid (GABA) production was investigated by thin-layer chromatography (TLC). Among the isolates, P. fermentans had an 85% total survival rate, but its amount reached below 6 log CFU/ml which is considered non-resistant, and it showed the highest auto-aggregation (74.67%). Moreover, only L. lactis showed antimicrobial activity and had the highest co-aggregation with E. coli PTCC 1338 (54.33%) and L. monocytogenes ATCC 7644 (78%). Finally, an evaluation of the technological and safety characteristics of the strains showed that the strains produced GABA and were safe. Although the isolates were not resistant to the gastrointestinal tract, their supernatant contained valuable natural compounds, including antioxidants, GABA, and antimicrobials, which can be used to produce functional foods and medicines. In addition, other approaches, such as increasing the initial number of strains, using foods as carriers of isolates, and encapsulating the isolates, can effectively increase the survivability of isolates in the gastrointestinal tract.

Identifying disulfidptosis subtypes in hepatocellular carcinoma through machine learning and preliminary exploration of its connection with immunotherapy

BackgroundHepatocellular carcinoma (HCC) is a highly prevalent and deadly cancer, with limited treatment options for advanced-stage patients. Disulfidptosis is a recently identified mechanism of programmed cell death that occurs in SLC7A11 high-expressing cells due to glucose starvation-induced disintegration of the cellular disulfide skeleton. We aimed to explore the potential of disulfidptosis, as a prognostic and therapeutic marker in HCC.MethodsWe classified HCC patients into two disulfidptosis subtypes (C1 and C2) based on the transcriptional profiles of 31 disulfrgs using a non-negative matrix factorization (NMF) algorithm. Further, five genes (NEIL3, MMP1, STC2, ADH4 and CFHR3) were screened by Cox regression analysis and machine learning algorithm to construct a disulfidptosis scoring system (disulfS). Cell proliferation assay, F-actin staining and PBMC co-culture model were used to validate that disulfidptosis occurs in HCC and correlates with immunotherapy response.ResultsOur results suggests that the low disulfidptosis subtype (C2) demonstrated better overall survival (OS) and progression-free survival (PFS) prognosis, along with lower levels of immunosuppressive cell infiltration and activation of the glycine/serine/threonine metabolic pathway. Additionally, the low disulfidptosis group showed better responses to immunotherapy and potential antagonism with sorafenib treatment. As a total survival risk factor, disulfS demonstrated high predictive efficacy in multiple validation cohorts. We demonstrated the presence of disulfidptosis in HCC cells and its possible relevance to immunotherapeutic sensitization.ConclusionThe present study indicates that novel biomarkers related to disulfidptosis may serve as useful clinical diagnostic indicators for liver cancer, enabling the prediction of prognosis and identification of potential treatment targets.Graphical

#2917 Desensitization techniques in ABO-incompatible renal transplantation: efficacy and analysis of complications

Abstract Background and Aims Living donor transplantation is the best optimal choice for the vast majority of patients with terminal renal insufficiency. However, it is limited by the AB0/ HLA incompatibility between donor and receptor. The resolution of this inconvenient relies on desensitization of isoagglutinins (anti-AB0 immunoglobulins depletion); thus transplantation could be performed safely. For desensitization there are two techniques: specific adsorption (S) and non-specific (NS) techniques, including centrifugal therapeutic plasma exchange (cTPE) and membrane-based therapeutic plasma exchange (mTPE). The aims are to evaluate the efficacy of apheresis techniques: specific versus non-specific, and identify their complications. Secondary objectives include analyzing the acute rejection rate (RR), graft survival, and complications of each technique. Method A retrospective cohort study was conducted on AB0-incompatible living donor transplantation patients at our center (Bellvitge's Hospital) from 2014 to 2022. All patients (except 1) received rituximab and induction treatment by Thymoglobulin or Basiliximab, followed by maintenance treatment (Steroids, Mycophenolate, and calcineurin inhibitors). During follow-up, protocol renal biopsies (RB) were taken at one month and between 3-6 months post-transplantation. Complications were defined as significant haematological alterations, bleeding, or major infections requiring hospitalization. According to the technique used, two cohorts were identified: specific (Glycosorb®/Vitrosorb® columns) and non-specific: mTPE (prismaflex TPE2000) and cTPE (Spectra/Optia®). Both were anticoagulated with heparin or citrate randomly. An expert nurse supervised the technique. To calculate the efficacy we considered the percentual reduction of isoagglutinins in the first session. T-student test was used to calculate the percentage of complication and compare the results. Results A total of 50 patients were selected with a mean age (MA) of 49.5 ± 11.8. Four of these did not require apheresis due to lower title isoagglutinins (&amp;lt;1/8). Each cohort included 23 patients: specific with MA 49.5 vs non-specific 48.4, with a mean isoagglutinin titles in specific of 61.65 vs non-specific 11.8 (p = 0.05). Isoagglutinin clearance were higher in specific techniques with 73% vs 59% non-specific (p &amp;lt; 0.03). Due to the dispersion in the number of sessions, results are expressed with the median (4 sessions in specific vs 3 non-specific). Total renal graft survival rate is 93.4%. At one month, it was diagnosed by biopsy an acute renal rejection rate of 16.7% in non-specific vs 18.2% specific (p &amp;gt; 0.05). Considering complications, they are higher with non-specific 41.7% vs specific 18% (p &amp;lt; 0.05). Regarding infectious issues, there are no differences in cytomegalovirus or polyomavirus infections, but there are differences in urinary infections observing in non-specific 79.2% vs specific 63% (p &amp;lt; 0.05). Conclusion Specific techniques are more effective in reducing isoagglutinins, show a lower rate of complications and post-transplant infections, providing greater benefit to the patient.

Histopathologic response in patients with curative resection with D2 dissection following neoadjuvant treatment for locally advanced gastric and esophagogastric junction adenocarcinoma

AimThis study evaluated pathologic response rate, overall survival (OS), and postoperative complications in locally advanced gastric cancer (GC) and esophagogastric junction (EGJ) adenocarcinoma patients who underwent curative gastric resection D2 lymph node dissection with neoadjuvant treatment. MethodsWe reviewed the medical records of 122 patients with locally advanced GC and EGJ adenocarcinoma who had neoadjuvant treatment and curative resection with D2 dissection between January 2014 and December 2022. Patients were divided into responders and nonresponders. Grades 1a-1b were responders, while 2–3 were non-responders. Patients' clinicopathological features, pathologic response rate, survival, and postoperative complications were evaluated. We assessed complications using the Clavien-Dindo (CD) classification. Total survival was assessed using the Kaplan-Meier model. Overall survival was assessed using univariate and multivariate Cox regression analysis. ResultsThe mean age of the study participants was 61 (N = 89 males; N = 33 females). There were 79 GC and 43 EGJ adenocarcinomas. Overall postoperative complications (CD ≥ II) were 27 %. Postoperative complications were similar in responders and non-responders (p = 0.316). YpT0N0 had a 2.5 % pathological complete response rate. Responders had better overall survival, but there was no statistical difference. ConclusionsBoth responder and non-responder groups have similar postoperative complications. A complete pathologic response is discouraging for assessing neoadjuvant chemotherapy for locally advanced gastric cancer, but a positive treatment response is acceptable. Pathologic response rate helps stage and predict gastric cancer prognosis. Responder groups survive slightly better.

Total knee arthroplasty survival rates are lower in younger men,as well as rheumatoid patients and after previous high-tibial osteotomy: A registry study.

The purpose of this study was to investigate if patient's gender significantly affected the long-term outcome of patients undergoing total knee arthroplasty (TKA) and to provide a cross-gender comparison of a large patient sample from a single regional register. The Registry of Prosthetic Orthopedic Implant of Emilia Romagna (RIPO) investigated all primary TKAs performed from July 2000 to December 2020 by collecting data of menand womenseparately. Primary bicompartmental and tricompartmental TKAs were included. The survival rates and the reasons for revision were assessed to check if any other factor could have influenced implantfailure. In total,66,032 TKAs were included and analysed, comprising 46,774 women and 19,258 men. The 15-year Kaplan-Meier survival percentage was 93.6% for womenand 92.5% formen (p = 0.001). Men exhibited a higher revision risk following primary TKA(p = 0.012), particularly when the primary diagnosis was arthritis resulting from rheumatic disorders (p = 0.018) and arthritis following high-tibial osteotomy (p = 0.024). Failure risk was also higher for men below the age of 60 years(p = 0.038). The long-term outcome in TKA showed significant differences between men and women, with a significantly lower survival rate in men at 15 years, especially when they areunder 60 years old or with a diagnosis of rheumatic disorders or arthritis following high-tibial osteotomy. It is necessary to design specific studies to have relevant data concerning gender differences in prosthetic surgery and to customise treatments to improve outcome and patient satisfaction.

Association between BMI and oncologic outcomes in epithelial ovarian cancer: a predictors-matched case-control study.

We aimed to study the association between obesity and survival in ovarian cancer (OC) patients, accounting for confounders as disease stage, histology, and comorbidities. Retrospective matched case-control study of consecutive patients, with epithelial OC. Obese (body mass index [BMI] ≥ 35 kg m-2) patients were matched in a 1:4 ratio with patients having lower BMIs (BMI < 35 kg m-2) based on disease stage, cytoreduction state, tumor histology and ASA score. We compared the 3-year and total recurrence-free survival and overall survival through Kaplan-Meier survival curves and Cox proportional hazards. Overall, 153 consecutive patients were included, of whom 32 (20.9%) had a BMI ≥ 35. and 121 a BMI < 35. The median follow-up time was 39 months (interquartile range 18-67). Both study groups were similar in multiple prognostic factors, including American Society of Anesthesiologists physical status, completion of cytoreduction, histology and stage of disease (p = 0.981, p = 0.992, p = 0.740 and p = 0.984, respectively). Ninety-five (62.1%) patients underwent robotic surgery and conversion rate from robotic to laparotomy was similar in both groups 2 (6.3%) in obese group vs. 6 (5.0%) in lower BMI patients, p = 0.673. During the follow-up time, the rate of recurrence was similar in both groups; 21 (65.6%) in obese group vs. 68 (57.1%), p = 0.387 and the rate of death events was similar; 16 (50.0%) in obese group vs. 49 (40.5%), p = 0.333). The 3-year OS was higher in the obese group (log rank p = 0.042) but the 3-year RFS was similar in both groups (log rank p = 0.556). Median total OS was similar in both groups 62 months (95% confidence interval 25-98 months) in obese vs. 67 months (95% confidence interval 15-118) in the lower BMI group, log rank p = 0.822. Median RFS was similar in both groups; 61 months (95% confidence interval 47-74) in obese, vs. 54 (95% confidence interval 43-64), log rank p = 0.842. In Cox regression analysis for OS, including obesity, age, laparotomy and neoadjuvant treatment - only neoadjuvant treatment was independently associated with longer OS: odds ratio 1.82 (95% confidence interval 1.09-3.05) and longer RFS: odds ratio 2.16 (95% confidence interval 1.37-3.41). In the present study on consecutive cases of ovarian cancer, obesity did not seem to be associated with outcome, except for an apparent improved 3-year survival that faded away thereafter.

A combination of lymphocyte count and albumin concentration as a new prognostic index for Hepatocellular Carcinoma

Aim The present study explores the prognostic significance of the lymphocytes (/L) × albumin (g/L) (LA) score and its relationship with the hepatocellular carcinoma. Material and Methods The study included patients who underwent curative surgery for hepatocellular carcinoma between January 2004 and November 2020. The LA score was calculated using the formula lymphocytes (/L)×albumin (g/L). The patients were subsequently divided into two as Group 1 (Low LA) and Group 2 (High LA). The two groups were compared for clinical characteristics as well as oncological follow-up outcomes. Results The study included 55 patients, who, based on an LA cut-off point of 4620, were divided into Group 1 (n=28) and Group 2 (n=27). The MELD score was higher in Group 1 (12 vs.9, p=0.022). The number of tumors, maximum tumor size and total tumor size were similar in both groups. At the last clinical follow-up, the mortality rate was 42.9% in Group 1 and 22.2% in Group 2. Recurrence rates were similar in both groups (42.9%vs.33.3% p=0.467), and total survival (126vs.164 months p=0.1) and disease-free survival (26 vs. 29 months p=0.926) were also similar. Conclusion The use of the composite LA index – an indicator of immunonutritional status as a prognostic marker may not be significant in HCC patients undergoing curative resection.

Effects of supplementation with different zinc-based products on the growth and health of Nile tilapia

Zinc is one of the essential microelements for the metabolism of animals. Zinc nanoparticles may have higher bioavailability due to their low specific surface area, facilitating absorption by fish. The present study aimed to evaluate the effects of supplementation with different zinc-based products on the growth and health of Nile tilapia Oreochromis niloticus. Zinc, in different sizes (nanoparticles or bulk) and forms (inorganic or organic), were used as a supplement in the tilapia diet at a dose of 15 mg kg feed−1 for 60 days. At the end of the feeding trial, production performance, hemato-immunological parameters, activity of antioxidant system enzymes, exposure to Streptococcus agalactiae and zinc concentration in the muscle were examined. After the bacterial challenge, the mean corpuscular hemoglobin concentration (MCHC) significantly increased in the fish treated with organic zinc, inorganic nano zinc, and organic nano zinc, while in the control group (inorganic zinc), MCHC remained unchanged. Regarding defense cells, dietary inorganic nano zinc increased the number of basophils (1.50 ± 1.10) compared to organic zinc (0.80 ± 0.90). Lymphocyte count increased after the challenge only in the organic zinc treatments (bulk and nanoparticles). Neutrophils decreased in the control (inorganic zinc) (2.20 ± 1.70) and inorganic nano zinc (2.60 ± 2.70) treatments after the challenge. When compared before and after the bacterial challenge, the plasma antimicrobial titer significantly increased after the bacterial challenge in all treatments. No significant differences were observed for total proteins, enzymes (SOD and CAT), cumulative survival and zinc deposition on fillet. In conclusion, organic zinc in nanoparticles or bulk size increased Nile tilapia innate defense during bacterial infection. However, the other parameters evaluated were not affected by zinc particle size or form (organic or inorganic), indicating that further evaluations should be conducted with organic zinc in nanoparticles or bulk size in the tilapia diet.

The Association of Body Composition Parameters Measured by Computed Tomography with Cancer Stage, Prognosis, and Survival in Patients with Renal Cell Carcinoma.

This study aims to investigate the association of preoperative body composition parameters, measured by computed tomography in patients undergoing surgery for renal cell carcinoma, with its stage and to survey the relationship with postoperative hospitalization duration and survival. Demographic data, pathology results, cancer stages, and hospitalization duration of 104 patients undergoing surgery at the urology clinic due to renal cell carcinoma between 2019 and 2023 were analyzed retrospectively. On computed tomography scans acquired during diagnosis, visceral adipose tissue, subcutaneous adipose tissue, total adipose tissue, and skeletal muscle area were measured. The ratios of body composition parameters were computed. When the correlation between survival time and body composition in deceased patients was analysed, a moderate but significant correlation was observed between skeletal muscle area value and total adipose tissue / skeletal muscle area ratio (r=0.630, p=0.001; r=0.598, p=0.002). A significant and strong correlation was observed between total adipose tissue value and survival (r=0.704, p<0.001). Subcutaneous adipose tissue / skeletal muscle area was found to be an independent risk factor associated with mortality, and a ratio of 0.98 or less increased the mortality risk approximately 16-fold. The relationship between body composition parameters measured by computed tomography, which can be easily evaluated pre-treatment, and mortality, postoperative recovery and length of hospital stay can be evaluated, giving clinicians an idea about the potential difficulties that patients may encounter during the treatment process. For this purpose, the subcutaneous adipose tissue / skeletal muscle area ratio is the most helpful parameter that can be used.</P>.

Pikeperch (Sander lucioperca) larval rearing optimization: utilization of lactic acid bacteria for improving microbiome diversity and digestive enzyme activity

Lactic acid bacteria (LAB) probiotics were evaluated for their impact on the microbiota and development of pikeperch (Sander lucioperca) larvae during their initial feeding stage (first 21 days). Pikeperch larvae were exposed to LAB probiotics in two ways: (1) via the live-feed only (Treatment 1, live-feed) or (2) via the live-feed and the larval culture water (Treatment 2, probiotic) in comparison to a control group without LAB supplementation. Total length (TL), myomere height (MH), and survival rate were significantly increased in the probiotic compared the Control group. The administration of probiotics significantly positively influenced the microbiome’s diversity. Specifically, the relative abundance of Cytophagales decreased and that of several other taxa increased in both probiotic treatments although differences between treatments became statistically insignificant by day 21. Furthermore, the different treatments had distinct and significant impacts on digestive enzyme development such as protease and lipase, with the most prominent differences occurring at seven days post-hatching (dph). Taken together, these results indicate that the use of LAB in both the live-feed and rearing water has a positive impact on the larvae microbiota and digestive enzyme development in turn positively impacting their development and viability under intensive rearing conditions.

Abstract 6495: Lenvatinib as a potential treatment option for invasive mucinous lung adenocarcinoma

Abstract Introduction: Invasive mucinous adenocarcinoma (IMA) accounts for approximately 4-20% of non-small-cell lung carcinoma (NSCLC). Genetic alterations and RNA sequencing analysis of IMAs reveal a unique mucinous signature similar to gastrointestinal mucinous tumors. Due to its rarity, focused clinical trials for IMA patients are often not feasible. These patients respond poorly to platinum-based conventional chemotherapy, or immunotherapy. Lenvatinib is a multitargeted-TKI with demonstrated activity in patients with RET fusion-positive lung adenocarcinoma, thyroid, hepatocellular and gastric carcinoma. Methods: Here, we present two RET fusion-negative mucinous lung adenocarcinoma cases that received a multitargeted TKI lenvatinib with a clinical and survival benefit. Results: Case #1: An 81-year-old female initially diagnosed with cT4N0M0 IMA (TTF1 and CDX2 focally positive) was started on neoadjuvant treatment for a 12cm tumor. She underwent right thoracotomy/right lower lobectomy/mediastinal lymph node dissection, and pathology confirmed ypT4N1M0 mucinous adenocarcinoma. Three months post-operatively, the patient had disease progression in the lungs. She had no targetable mutations. She had four subsequent lines of treatment including nivolumab/nab-paclitaxel as the fourth-line treatment. After six months of nivolumab/nab-paclitaxel, lenvatinib was added to the combination due to clear disease progression evident on imaging. After twelve cycles of nivolumab/nab-paclitaxel/lenvatinib combination treatment, patient achieved a partial response per RECIST 1.1 (-35.7% change from baseline to current). The patient reported less dyspnea and increased activity tolerance. Approximately nine months after the start of the treatment, patient showed progressive lung disease. The patient died after one more line treatment with 41 months of total overall survival. Case#2: A 56-year-old male initially diagnosed with stage IVA IMA (TTF1 negative). After four lines of treatments, patient was started on lenvatinib alone. The patient reported marked improvement in dyspnea and pain and increased activity tolerance with lenvatinib. Imaging confirmed treatment response after three months of treatment. The patient was subsequently enrolled in the double lung transplant (DLT) registry aimed for lung-limited malignancies (D.R.E.A.M.) registry study (NCT05671887), and he is alive with 25 months follow-up since DLT. Conclusion: We report two cases of metastatic RET fusion-negative mucinous lung adenocarcinoma, in which treatment with the multitargeted TKI Lenvatinib led to significant clinical improvement. Biological rationale to explain the effect of lenvatinib in invasive mucinous lung adenocarcinoma needs to be explored.

Effect of an Airbag-selective Portal Vein Blood Arrester on the Liver after Hepatectomy: A New Technique for Selective Clamping of the Portal Vein.

A novel technique was explored using an airbag-selective portal vein blood arrester that circumvents the need for an intraoperative assessment of anatomical variations in patients with complex intrahepatic space-occupying lesions. Rabbits undergoing hepatectomy were randomly assigned to 4 groups: intermittent portal triad clamping (PTC), intermittent portal vein clamping (PVC), intermittent portal vein blocker with an airbag-selective portal vein blood arrester (APC), and without portal blood occlusion (control). Hepatic ischemia and reperfusion injury were assessed by measuring the 7-day survival rate, blood loss, liver function, hepatic pathology, hepatic inflammatory cytokine infiltration, hepatic malondialdehyde levels, and proliferating cell nuclear antigen levels. Liver damage was substantially reduced in the APC and PVC groups. The APC animals exhibited transaminase levels similar to or less oxidative stress damage and inflammatory hepatocellular injury compared to those exhibited by the PVC animals. Bleeding was significantly higher in the control group than in the other groups. The APC group had less bleeding than the PVC group because of the avoidance of portal vein skeletonization during hepatectomy. Thus, more operative time was saved in the APC group than in the PVC group. Moreover, the total 7-day survival rate in the APC group was higher than that in the PTC group. Airbag-selective portal vein blood arresters may help protect against hepatic ischemia and reperfusion injury in rabbits undergoing partial hepatectomy. This technique may also help prevent liver damage in patients requiring hepatectomy.

Climate change-induced shifts in survival and size of the worlds' northernmost oviparous snake: A 68-year study.

Because of their dependence on ambient temperature ectothermic animals can serve as sentinels of conservation problems related to global warming. Reptiles in temperate areas are especially well suited to study such effects, as their annual and daily activity patterns directly depend on ambient temperature. This study is based on annual data spanning 68 years from a fringe population of Grass Snakes (Natrix natrix), which is the world's northernmost oviparous (egg-laying) reptile, and known to be constrained by temperature for reproduction, morphology, and behavior. Mark-recapture analyses showed that survival probability was generally higher in males than in females, and that it increased with body length. Body condition (scaled mass index) and body length increased over time, indicative of a longer annual activity period. Monthly survival was generally higher during winter (i.e., hibernation) than over the summer season. Summer survival increased over time, whilst winter survival decreased, especially during recent decades. Winter survival was lower when annual maximum snow depth was less than 15 cm, implying a negative effect of milder winters with less insulating snow cover. Our study demonstrates long-term shifts in body length, body condition and seasonal survival associated with a warming climate. Although the seasonal changes in survival ran in opposite directions and though changes were small in absolute terms, the trends did not cancel out, but total annual survival decreased. We conclude that effects of a warming climate can be diverse and pose a threat for thermophilic species in temperate regions, and that future studies should consider survival change by season, preferably in a long-term approach.

Evaluating different rates of activated carbon in commercially produced seed coatings in laboratory and field trials

Pre‐emergent herbicides, commonly employed for managing invasive annual plants, often fail to meet restoration targets due to the absence of remnant perennial plants, which leaves sites vulnerable to re‐invasion and hinders effective control of annual grasses. Combining an herbicide treatment with seeding is therefore desirable, but seeded plants can also be negatively impacted by pre‐emergent herbicides. Herbicide protection (HP) seed technologies use activated carbon to adsorb herbicide near seeds and have shown promise for allowing simultaneous deployment of herbicide and seed, but recent research recommends numerous additional refinements be tested. We addressed some of these recommendations through one laboratory and a field trial replicated at multiple sites to explore whether commercially produced, single‐seed HP coatings with two different rates of activated carbon can prevent herbicide‐related damage to two perennial bunchgrasses native to the western United States. We also investigated how these coated prototypes compare in performance to the multi‐seed extruded herbicide protection pellets (HPPs) tested in prior research. In the laboratory, neither coating treatment reduced total emergence, emergence rate, survival, or biomass in the absence of herbicide. In the presence of herbicide, both provided several‐fold higher survival and aboveground biomass compared to untreated bare seed, but this represented incomplete protection from herbicide. In field trials where conditions were harsher than the laboratory, we found no evidence of HP from any treatment, and HPPs reduced seedling count for one species. We conclude that the tested HP coating prototype is an improvement over HPPs but requires additional refinements and testing.

Modelling the Effectiveness of Tepotinib in Comparison to Standard-of-Care Treatments in Patients with Advanced Non-small Cell Lung Cancer (NSCLC) Harbouring METex14 Skipping in the UK.

Patients with non-small cell lung cancer harbouring mesenchymal-epithelial transition exon 14 (METex14) skipping typically demonstrate poorer prognosis than overall non-small cell lung cancer. Until recently, no targeted treatments were available for patients with non-small cell lung cancer harbouring METex14 skipping in the UK, with limited treatments available. This study estimates the long-term survival and quality-adjusted life-year benefit of MET inhibitor tepotinib versus current standard of care from a UK perspective. A partitioned-survival model assessed the survival and quality-adjusted life-year benefits of tepotinib versus immunotherapy ± chemotherapy and chemotherapy for untreated and previously treated patients, respectively, using evidence from the single-arm VISION trial (NCT02864992). Two approaches were used to inform an indirect treatment comparison: (1) published clinical trials in overall non-small cell lung cancer and (2) real-world evidence in the METex14 skipping population. Results are presented as median and total quality-adjusted life-year gain and survival for progression-free survival and overall survival. Survival curves were validated against the external literature and uncertainty assessed using a probabilistic sensitivity analysis. Using the indirect treatment comparison against the published literature, tepotinib is estimated to have a median progression-free survival gain versus pembrolizumab ± chemotherapy (11.0 and 9.2 months) in untreated patients, and docetaxel ± nintedanib (5.1 and 6.4 months) in previously treated patients. Across the populations, tepotinib is estimated to have a median survival gain of 15.4 and 9.2 months versus pembrolizumab ± chemotherapy in untreated patients and 12.8 and 5.1 months versus docetaxel ± nintedanib in previously treated patients. The total quality-adjusted life-year gain ranges between 0.56 and 1.17 across the untreated and previously treated populations. Results from the real-world evidence of indirect treatment comparisons are consistent with these findings. Despite the limitations of the evidence base, the numerous analyses conducted have consistently indicated positive outcomes for tepotinib versus the current standard of care.

Effects of Tribulus terrestris and Basella alba Extract on Sex Reversal on Poecilia reticulata

This study examined the effects of Tribulus terrestris and Basella alba on sex reversal in the guppy, Poecilia reticulata. This study aimed to introduce a new environmentally friendly method for masculinization in P. reticulata. Since male guppy has higher commercial value than females. T. Terrestris (ET) and Basella alba (EB) are a natural, non-toxic herb that helps enhance testosterone levels in humans and animals. Different concentrations (0.0, 5.0, 10.0, and 15.0 g L-1) of ET and EB were investigated for sex reversal in P. reticulata. The plant extracts were administered by immersion of newly hatched offspring once a week for two months. The dosage of 15.0, g L-1 ET was the most effective dosage that ensured a maximum male ratio (82.0, p&lt;0.01). Although, sex ratios of fish in treatment 5.0 and 10.0 g L-1 ET were not significantly different from the expected 1:1 ratio, in these two groups treatment with ET and EB also resulted in a higher number of males (71.9 and 61.1; 82.0 and 78.5, respectively), than control (p&gt;0.05). Total survival rates in all treatments and control were uniformly high ranging from 92% and 97% (p&gt;0.05). It is concluded that ET has no negative effect on the survival rate of P. reticulata. All groups of ET-treated fish exhibited growth acceleration compared to the control group, but only ET treatment at the concentration of 15 and 10 g L-1 ET significantly improved growth rate of P. reticulata (p&lt;0.01). Histological examinations revealed that the testes of fish treated with ET and EB extract contained all stages of spermatogenesis. Sex reversal in P. reticulata demonstrated that ET and EB-treated progenies showed successful sex reversal, spermatogenesis, and better growth rate than untreated progenies.

Therapeutic efficacy of high-dose chemotherapy with autologous stem-cell transplantation in 44 relapsed or refractory germ-cell tumor patients: A retrospective cohort study.

Despite having a higher mortality risk than conventional chemotherapeutics, high-dose chemotherapy (HDCT) has the potential to be curative in relapsed/refractory germ-cell tumors. Therefore, selecting the best patient group for this treatment is critical. This study aimed to determine the factors that affect survival in our relapsed/refractory GCT cohort who received HDCT and autologous stem-cell transplantation. Between September 2010 and 2020, we included in the study 44 relapsed/refractory male patients with GCT treated with HDCT plus autologous stem-cell transplantation. The patients' demographic features, clinical characteristics, and treatment outcomes were evaluated. Statistical analyses were performed to identify risk factors associated with survival. The median age of all cohorts was 28 years. Thirty-six patients had nonseminomatous tumors, and 8 patients had seminomatous tumors. The most common primary tumor sites were the gonads (75%), followed by the mediastinum (15.9%) and the retroperitoneum (9.1%). After HDCT, 11 patients had a complete response, 12 patients had a partial response, and 17 patients had a progressive disease, respectively. About 23 patients (52.3%) experienced at least 1 treatment-related grade 3 to 4 nonhematological toxicity. About 4 patients (10%) died due to HDCT-related toxicity. The total group's median progression-free survival (PFS) was 7 months, and the median overall survival (OS) was 14.9 months. Primary tumor site (hazard ratio [HR]: 1.84; P = .028), type of HDCT regimen (HR: 0.35; P = .010), and best response to HDCT (HR: 11.0; P < .0001) were independent prognostic risk factors for PFS. The only independent prognostic risk factor associated with OS was the best response to HDCT (HR: 6.62; P = .001). The results of the study promise the best response to HDCT as a primary measure for predicting survival in relapsed/refractory GCT. In contrast, primary mediastinal GCT is not a good candidate for HDCT. Furthermore, a carboplatin-etoposide regimen in combination with cyclophosphamide and paclitaxel may improve PFS.

Correlation between prognostic nutritional index and pleural thickness with survival time of epithelial malignant pleural mesothelioma patients

Objective: To explore the role of prognostic nutritional index (PNI) and pleural thickness in the prognostic evaluation of patients with epithelial malignant pleural mesothelioma (MPM) . Methods: In April 2022, a retrospective analysis was conducted on the data and laboratory data of 41 patients with epithelial MPM admitted to the cardiothoracic surgery department of Chuxiong Yi Autonomous Prefecture People's Hospital from January 2018 to May 2021. Univariate and multivariate analysis were used to evaluate the relationships between total survival time, clinical characteristics, PNI and pleural thickness in patients. Results: The 41 patients were mostly male (26 cases, 63.4%) , with a median age of 55 years old. The main clinical manifestations were chest pain (53.7%) , bloody pleural effusion (75.6%) , and chest pain combined with bloody pleural effusion (36.6%) . The median survival time of patients with different TNM stage, efficacy after 4 cycles of chemotherapy, PNI, maximum pleural thickness after chemotherapy (post max) , sum of post max in 3 zones after chemotherapy (post sum) were statistically different (χ(2)=3.89, 14.51, 15.33, 4.33, 12.05, P<0.05) . Compared with patients with high PNI and post sum<32.26 mm, MPM patients with low PNI and post sum≥32.26 mm have higher risk of death, and the differences were statistically significant (HR=1.52, 95%CI: 1.75-11.93, P=0.002; HR=1.70, 95%CI: 1.84-16.23, P=0.002) . Conclusion: PNI and post sum can be used to predict the prognosis of patients with epithelial MPM.

Growth, Hematological Evaluation and Heavy Metal Bioaccumulation in Nile Tilapia (Oreochromis niloticus) from A Municipal Waste Landfill Reservoir

The aim of this study was to evaluate the growth performance, mortality rate, and blood profile of Cd-, Pb-and Cr-contaminated Nile tilapia from the Khon Kaen municipal waste landfill reservoir and compare the parameters with those of fish from unpolluted sites. Human bioaccumulation factor (BAF) determination was also performed. Thirty samples of Nile tilapia were taken from the Khon Kaen municipal waste landfill reservoir (CN) and from unpolluted (TN) ponds. Water and soil were collected from these sites, and tilapia muscle, gill, and liver were obtained for heavy metal evaluation. The Cd concentrations in the muscle, gill and liver were 0.003 ± 0.001, 0.006 ± 0.008, and 0.004 ± 0.003 mg/kg; the Pb concentrations were 0.078 ± 0.173, 0.880 ± 1.360 and 1.110 ± 1.862 mg/kg; and the Cr concentrations were 0.067 ± 0.135, 0.572 ± 1.098 and 0.636 ± 1.272 mg/kg, respectively. The total fish length, body weight and survival rate were significantly lower in the TN group (P &lt;0.05), and alanine aminotransferase and creatinine were significantly (P &lt;0.05) higher in the TN group. The hematocrit count of the TN group was also lower than that of the CN group but without a significant difference. The BAF ranged from 0.1-4.3, especially in the gills and liver, which are major heavy metal accumulation organs. Heavy metal contamination in landfill leachate negatively affects fish health and its production. Keywords: Aquaculture, Nile tilapia, Heavy metal, Pathology, Toxicity
