Introduction Previous studies suggested that type O blood may be associated with increased mortality and/or thrombotic complications among trauma patients. The purpose of this analysis was to evaluate the relationship between endogenous blood type, mortality, and complications among patients receiving massive transfusions, using data from the Pragmatic Randomized Optimal Platelet and Plasma Ratios trial. Materials and Methods This was a secondary analysis of the Pragmatic Randomized Optimal Platelet and Plasma Ratios trial that included patients with the reported blood type (A, AB, B, or O) data. Outcomes were early and late mortality and clinical complications. Endogenous von Willebrand Factor (vWF) antigen levels, vWF activity, and factor VIII levels were measured with admission labs and compared. Logistical regression was used to assess associations between mortality and blood type. Results Among 680 patients, 655 who had admission blood type data were included. 322 (49.2%) were type O, 186 (28.4%) were type A, 27 (4.1%) were type AB, and 120 (18.3%) were type B. The mean age, gender distribution, mechanism of injury, injury severity, and injury patterns were similar between blood types. There were significant racial and ethnic differences (P < 0.001 and P < 0.0018, respectively), and patients with endogenous type O blood had decreased levels of vWF activity and vWF antigen (P = 0.022 and P = 0.016, respectively). Logistical analyses showed no significant associations between blood type and complications, and type O blood was not associated with increased mortality. Conclusions We found that endogenous blood type was not associated with increased mortality or clinical complications in severely injured patients requiring massive transfusion based on the data from a large multicenter trial.

Bioscience encompasses studies on living organisms, their components, and their interactions, with the main aim of translating research into useful applications for medical, clinical, industrial, and environmental uses. The broad field of bioscience has witnessed tremendous growth in research output. This study was designed to evaluate the current trends in bioscience research using bibliometric approaches and develop future policy pointers following the innovative systems framework. Research articles focusing on bioscience published between 1883 and 2024 were sourced from the Scopus database. From the retrieved dataset, relevant articles were systematically screened and included for the analysis. Bibliometrix package, VOSviewer, and Microsoft Excel were used to analyze and visualize the parameters. 8,678 documents involving 30,380 authors from diverse institutions across the globe were published in 3,549 sources, with an annual rise of 4.41%. Exponential growth in bioscience research output was observed after 2007 and remained steady till 2024. The United States and China were leading nations for bioscience research. The most relevant affiliation was the University of California, United States, while the most relevant source was the Brazilian Journal of Medical and Biological Research , in terms of the number of publications. Among the authors, Wang Y had the highest number of documents, while the most impactful author was Zhang J. The most frequent keywords in bioscience research included biological research , genetics , procedures , metabolism , biology , DNA , gene expression , proteins , genomics , and fluorescence . Furthermore, themes such as bioinformatics , microRNA , synthetic biology, CRISPR/Cas9 , deep learning , multi-omics , and big data represented the recent research interests. The bioscience research landscape is defined by the dominance of high-income countries and a shift toward omics-driven and data-intensive approaches. Yet global participation remains uneven, with limited representation from low- and middle-income regions. This study highlights the need for inclusive, globally coordinated strategies that foster equitable access, capacity building, and cross-regional collaboration. ### Competing Interest Statement The authors have declared no competing interest.

BACKGROUND:Hyperparathyroidism (HPT) and malignancy are the most common causes of hypercalcemia. Among kidney transplant (KT) recipients, hypercalcemia is mostly caused by tertiary HPT. Persistent tertiary HPT after KT is associated with allograft failure. Previous studies on managing tHPT were subjected to survivor treatment selection bias; as such, the impact of tertiary HPT treatment on allograft function remained unclear. We aim to assess the association between hypercalcemic tertiary HPT treatment and kidney allograft survival. MATERIALS AND METHODS:We identified 280 KT recipients (2015-2019) with elevated post-KT adjusted serum calcium and parathyroid hormone (PTH). KT recipients were characterized by treatment: cinacalcet, parathyroidectomy, or no treatment. Time-varying Cox regression with delayed entry at the time of first elevated post-KT calcium was conducted, and death-censored and all-cause allograft failure were compared by treatment groups. RESULTS:Of the 280 recipients with tHPT, 49 underwent PTx, and 98 received cinacalcet. The median time from KT to first elevated calcium was 1 month (IQR: 0-4). The median time from first elevated calcium to receiving cinacalcet and parathyroidectomy was 0(IQR: 0-3) and 13(IQR: 8-23) months, respectively. KT recipients with no treatment had shorter dialysis vintage (P = .017) and lower PTH at KT (P = .002), later onset of hypercalcemia post-KT (P < .001). Treatment with PTx (adjusted hazard ratio (aHR) = 0.18, 95%CI 0.04-0.76, P = .02) or cinacalcet (aHR = 0.14, 95%CI 0.004-0.47, P = .002) was associated with lower risk of death-censored allograft failure. Moreover, receipt of PTx (aHR = 0.28, 95%CI 0.12-0.66, P < .001) or cinacalcet (aHR = 0.38, 95%CI 0.22-0.66, P < .001) was associated with lower risk of all-cause allograft failure. CONCLUSIONS:This study demonstrates that treatment of hypercalcemic tertiary HPT post-KT is associated with improved allograft survival. Although these findings are not specific to hypercalcemia of malignancy, they do demonstrate the negative impact of hypercalcemic tertiary HPT on kidney function. Hypercalcemic HPT should be screened and aggressively treated post-KT.

IntroductionTotal thyroidectomy is the traditional primary approach for papillary thyroid cancer. However, recent evidence supports conservative management for low-risk tumors like papillary thyroid microcarcinomas (PTMCs). This study explores the adoption of these practices in our community, using a cancer database to analyze treatment strategies.MethodsA retrospective review of a 1433-patient institutional database identified 258 PTMC cases. Outcomes, including 30-day mortality, reoperation rate, postoperative hypocalcemia, and recurrent laryngeal nerve (RLN) injury, were assessed.ResultsOf PTMC patients, 63.4% underwent total thyroidectomy, with higher rates of RLN injury (8.8% vs. 2.3%) and hypocalcemia (12.4% vs. 0.0%) compared to lobectomy. Non-endocrine surgeons had higher postoperative radioactive iodine administration rates (28.6% vs. 6.1%). Subgroup analysis revealed a shift in total thyroidectomy rates based on tumor size and surgery period.ConclusionOur community favors total thyroidectomy for PTMC, despite associated complications. Enhanced awareness and adherence to PTMC best practice guidelines are warranted.

Thyroid nodules are widely prevalent, and often discovered incidentally. Malignancy rates are low for incidental thyroid nodules, and overall outcomes are favorable regardless of diagnosis. Patients with thyroid nodules should be evaluated with TSH levels followed by ultrasound of the thyroid and cervical lymph nodes. It is important to recognize sonographic features suspicious for thyroid malignancy and obtain biopsies when indicated according to major society guidelines. The Bethesda System for Reporting Thyroid Cytopathology along with molecular testing can help guide management decisions regarding thyroid nodules. Surgical resection and other emerging technologies are safe and effective for the treatment of thyroid nodules needing intervention.

Background:Data remains limited as to whether the order of pulmonary vessel division during performance of a lobectomy for non-small cell lung cancer (NSCLC) affects survival outcomes. Some authors have suggested that ligation of the pulmonary veins should be conducted first in order to minimize the spread of tumor cells secondary to manipulation of the lung. This study examines whether there is a difference in outcomes between patients who undergo robotic lobectomies for NSCLC using a vein-first (V-first) vs. artery-first (A-first) technique.Methods:A retrospective review of electronic medical record data was performed for patients who underwent robotic lobectomies from January 2013 to May 2019. Patients were separated into two groups based on the sequence in which the pulmonary vessels were divided: V-first or A-first. Baseline characteristics and postoperative events were recorded and compared between groups using Chi-squared and Student's t-tests. Kaplan-Meier survival curves for overall and recurrence-free survival were constructed and compared with log-rank tests.Results:A total of 374 patients were identified: 94 V-first and 280 A-first patients. There was no significant difference between the V-first and A-first groups with regards to postoperative complications, length of stay, recurrence-free survival, or overall survival.Conclusions:Our study suggests that choosing a V-first vs. A-first technique for a robotic lobectomy does not significantly impact overall survival or cancer recurrence for patients with NSCLC. Further studies are needed to evaluate whether the order of pulmonary vessel resection affects outcomes for patients with NSCLC.

Introduction: The Assessment of Blood Consumption (ABC) score is used to predict massive transfusions (MT). However, its diagnostic performance has not been widely examined, especially when used as an objective tool to enroll patients in multi-center clinical trials. The purpose of this study was to evaluate the performance of the ABC score in enrolling patients in the Pragmatic Randomized Optimal Platelet and Plasma Ratios (PROPPR) trial. We hypothesized the ABC score would have a similar diagnostic performance to predict the need for massive transfusion as previous studies. Methods: This is a retrospective analysis of the PROPPR trial. Patients were enrolled either on the basis of an ABC score >= 2, or by Physician Gestalt, when the ABC score was <2. We calculated the sensitivity, specificity, positive (PPV) and negative (NPV) predictive values and likelihood ratios of the ABC score (>= 2) for predicting MT (>10 units of red blood cells/24 h or transfusion of >3 units of red blood cells within the first hour). Results: Of the 680 patients, 438 patients (64 %) had an ABC score of >= 2 and 242 (36 %) had an ABC score of <2. An ABC score of >= 2 had 66.8 % sensitivity and 37.0 % specificity for predicting the need for MT, with a PPV of 88.2 % and NPV of 13.1 %. Similarly, an ABC >= 2 had 65.6 % sensitivity and 44.6 % specificity for predicting the need for >3 units RBCs in 1 hour, with a PPV of 89.5 % and NPV of 15.3 %. Conclusion: The ABC score had lower performance than previously reported for predicting MT, when applied to PROPPR trial patients. The performance for predicting the need for a 3-unit red blood cell transfusion (or more) in the first hour was slightly higher.

ABSTRACT Introduction The Pragmatic Randomized Optimal Platelet and Plasma Ratios (PROPPR) trial rapidly enrolled patients based on an ABC ≥ 2 score, or Physician Gestalt (PG) when ABC score was <2. The objective of this study was to describe what patients were enrolled by the two methods and whether patient outcomes differed based these enrollments. We hypothesized that there would be no differences in outcomes based on whether patients were enrolled via ABC score or PG. Methods Patients were enrolled with an ABC ≥ 2 or by PG when ABC was <2 by the attending trauma surgeon. We compared 1-, 3-, 6-, 12-, 18- and 24-hour mortality, 30-day mortality, time to hemostasis, emergent surgical or interventional radiology procedure and the proportion of patients who required either >10 units of blood in 24 hours or > 3 units in one hour. Results Of 680 patients, 438 (64%) were enrolled on the basis of an ABC score ≥ 2 and 242 (36% by PG when the ABC score was <2. Patients enrolled by PG were older (median 44, IQR 28-59, p < 0.001), more likely to be white (70.3% vs 60.3%, p = 0.014), and more likely to have been injured by blunt mechanisms (77.3% vs 37.2%, p < 0.001). They were also less hypotensive and less tachycardic than patients enrolled by ABC score (both p < 0.001). The groups had similar Injury Severity Scores in the ABC ≥ 2 and PG groups (26 and 27 respectively) and were equally represented (49.1% and 50.8% respectively) in the 1:1:1 treatment arm. There were no significant differences between the ABC score and PG groups for mortality at any point. Time to hemostasis (108 for patients enrolled on basis of Gestalt, vs. 100 mins for patients enrolled on basis of ABC score), and the proportion of patients requiring a massive transfusion (>10 units/24 h) (44.2% vs. 47.3%), or meeting the critical administration threshold (>3 unit/1 hr) (84.7% vs. 89.5%) were similar (p = 0.071) Conclusion Early identification of trauma patients likely to require a massive transfusion is important for clinical care, resource use, and selection of patients for clinical trials. Patients enrolled in the PROPPR trial based on PG when the ABC score was <2 represented 36% of the patients and had identical outcomes to those enrolled on the basis of an ABC score of ≥2.

Tumor necrosis factor alpha (TNF-α)/hypoxia-treated 3T3-L1 adipocytes have been used to model inflamed and insulin-resistant adipose tissue: this study examines gaps in the model. We tested whether modulating TNF-α/hypoxia treatment time could reduce cell death while still inducing inflammation and insulin resistance. Adipocytes were treated with TNF-α (12 h or 24 h) and incubated in a hypoxic chamber for 24 h. To examine maintenance of the phenotype over time, glucose and FBS were added at 24 h post initiation of treatment, and the cells were maintained for an additional 48 h. Untreated adipocytes were used as a control. Viability, insulin resistance, and inflammation were assessed using Live/Dead staining, RT-qPCR, ELISA, and glucose uptake assays. Treatment for 12 h with TNF-α in the presence of hypoxia resulted in an increase in the percentage of live cells compared to 24 h treated cells. Importantly, insulin resistance and inflammation were still induced in the 12 h treated adipocytes: the expression of the insulin sensitive and inflammatory genes was decreased and increased, respectively. In 72 h treated adipocytes, no significant differences were found in the viability, glucose uptake or insulin-sensitive and inflammatory gene expression. This study provides a modified approach to in vitro odeling adipocyte inflammation and insulin resistance.        .

The use of blood products for resuscitation has long been rooted in lessons learned from war. From preliminary attempts at blood transfusion during the Civil War to massive transfusion protocols in modern warfare, advances in the knowledge of blood products and their effective use in traumatic resuscitation has evolved through conflict. The last century in particular has seen multiple shifts in resuscitative strategies. World War I saw the first widespread introduction of blood as a resuscitation agent. By the end of the war, storage banks, crossmatching, and whole blood transfusions were employed throughout American and British field hospitals. Whole blood resuscitation inexplicably fell out of favor in the decades that followed until World War II. Experiences with high casualty rates due to hemorrhagic shock during World War II prompted a shift back toward whole blood and away from primary plasma resuscitation. The separation of whole blood into components for storage and transport first occurred on a large scale during the Vietnam War, and this popularized component therapy for many decades. Military experience in Iraq and Afghanistan led to many key trials in the early 2000s that supported the use of balanced blood product resuscitation. Current guidelines recommend a 1:1:1 ratio of blood products with minimal administration of crystalloid fluids. Nonrandomized studies show a survival benefit for whole blood resuscitation in civilian and military settings, and most authors agree that whole blood is logistically easier to transfuse at the bedside. Randomized clinical trials will need to be conducted to show whether whole blood has a clear survival advantage over balanced resuscitation with component therapy.

Introduction: Acute pain is common after injury. This study intended to evaluate the feasibility of quantifying pain experience over an entire admission using "area under the pain curve" and to identify factors associated with increased pain. Methods: This retrospective single-center study included all trauma patients admitted from 2013 to 2020. Maximum pain scores were extracted for each day. Pain was defined as area under the curve (AUC) of maximum pain scores/day plotted against time. Injury patterns were analyzed by dichotomizing Abbreviated Injury Scale (AIS) scores (AIS < 3 versus AIS > 3) for each body region. Urinary drug screen results were collected from admission data. A general linear model was used to determine which injury patterns, mechanisms, and age groups were predictive of increased AUC in all patients together and separate by operative and nonoperative groups. Results: We identified 21,640 patients, of which 70% were male and 83% had suffered blunt injury. Overall injury severity was associated with increased pain experience. Serious head injury, younger age, and older age (compared to 45-49 y) were associated with decreased pain. Spinal injuries, thoraco-abdominal injuries, and combined thoracic and lower extremity injuries were predictive of increased pain. Compared to patients with no positive test for illicit substances or documentation of prehospital narcotic medications, the pain experience was greater for both, those who had been administered a narcotic in the prehospital setting and those who tested positive for illicit substances. Conclusions: This study extends the concept of total pain experience using AUC methodology. Our results demonstrate associations between increased pain and certain patterns of injury, ages, and presence of drugs on admission. Measuring total pain experience could assist in comparing pain-management strategies. Future research should focus on validating pain experience against quality-of-life measurements. & COPY; 2023 Elsevier Inc. All rights reserved.

Introduction: With shrinking National Institute of Health support, increased clinical demands, and less time for research training during residency, the future of surgeon scientists is in jeopardy. We evaluate the role of a structured research curriculum and its association with resident academic productivity.Methods: Categorical general surgery residents who matched between 2005 and 2019 at our institution were analyzed (n = 104). An optional structured research curriculum, including a mentor program, grant application support, didactic seminars, and travel funding was implemented in 2016. Academic productivity, including the number of publications and citations, was compared between residents who started in or after 2016 (post-implementation, n = 33) and those before 2016 (preimplementation, n = 71). Descriptive statistics, Mann-Whitney U test, multivariable logistic regression, and inverse probability treatment weighting were performed.Results: The postimplementation group had more female (57.6% versus 31.0%, P = 0.010), and nonwhite (36.4% versus 5.6%, P < 0.001) residents and had more publications and citations at the start of residency (P < 0.001). Postimplementation residents were more likely to choose academic development time (ADT) (66.7% versus 23.9%, P < 0.001) and had higher median (IQR) number of publications (2.0 (1.0-12.5) versus 1.0 (0-5.0), P = 0.028) during residency. After adjusting the number of publications at the start of residency, multivari-able logistic regression analysis showed that the postimplementation group was five times more likely to choose ADT (95% CI 1.7-14.7, P = 0.04). Further, inverse probability treatment weighting revealed an increase of 0.34 publications per year after implementing the structured research curriculum among residents who chose ADT (95% CI 0.1-0.9, P = 0.023).Conclusions: A structured research curriculum was associated with increased academic productivity and surgical resident participation in dedicated ADT. A structured research curriculum is effective and should be integrated into residency training to support the next generation of academic surgeons.

Ornamental plants require their visual characteristics to be preserved to serve their decorative purposes as constituents of natural living beauty in the environment. In the various strategies developed over the years toward improving the shelf life of ornamental plants, evaporative coolant structures have emerged as a user-friendly approach. As a technique where the evaporation of water both directly and indirectly cools the stream of air, this technology offers great potential in maintaining the artistic relevance of ornamental plants. Evaporative coolant structures provide economic, eco-friendly, and health advantages compared to other methods. In addition, the technology is highly sustainable and has prospects for broad application in harvesting and postharvest care of ornamental plants, especially with the recent advancements in the humidification-dehumidification cycle, fresh air handling and conditioning system, and heat recovery system of the evaporative coolers. This chapter describes the role of evaporative coolers in ornamental plants, the basics of designing evaporative structures, and various practical and technical modifications required to obtain better efficiency for application in ornamental plants.
