C. elegans foraging as a model for understanding the neuronal basis of decision-making
Authors: Haley Jessica A. , Chalasani Sreekanth H. 
Published: June 2024

AbstractAnimals have evolved to seek, select, and exploit food sources in their environment. Collectively termed foraging, these ubiquitous behaviors are necessary for animal survival. As a foundation for understanding foraging, behavioral ecologists established early theoretical and mathematical frameworks which have been subsequently refined and supported by field and laboratory studies of foraging animals. These simple models sought to explain how animals decide which strategies to employ when locating food, what food items to consume, and when to explore the environment for new food sources. These foraging decisions involve integration of prior experience with multimodal sensory information about the animal’s current environment and internal state. We suggest that the nematode Caenorhabditis elegans is well-suited for a high-resolution analysis of complex goal-oriented behaviors such as foraging. We focus our discussion on behavioral studies highlighting C. elegans foraging on bacteria and summarize what is known about the underlying neuronal and molecular pathways. Broadly, we suggest that this simple model system can provide a mechanistic understanding of decision-making and present additional avenues for advancing our understanding of complex behavioral processes.
Stress-constrained optimization of multiscale structures with parameterized microarchitectures using machine learning
Authors: Black Nolan , Najafi Ahmad 
Published: June 2024

AbstractA multiscale topology optimization framework for stress-constrained design is presented. Spatially varying microstructures are distributed in the macroscale where their material properties are estimated using a neural network surrogate model for homogenized constitutive relations. Meanwhile, the local stress state of each microstructure is evaluated with another neural network trained to emulate second-order homogenization. This combination of two surrogate models — one for effective properties, one for local stress evaluation — is shown to accurately and efficiently predict relevant stress values in structures with spatially varying microstructures. An augmented lagrangian approach to stress-constrained optimization is then implemented to minimize the volume of multiscale structures subjected to stress constraints in each microstructure. Several examples show that the approach can produce designs with varied microarchitectures that respect local stress constraints. As expected, the distributed microstructures cannot surpass density-based topology optimization designs in canonical volume minimization problems. Despite this, the stress-constrained design of hierarchical structures remains an important component in the development of multiphysics and multifunctional design. This work presents an effective approach to multiscale optimization where a machine learning approach to local analysis has increased the information exchange between micro- and macroscales.
Arbitrariness of bibliometric parameters: a case study on leading scientists in the German Society for Experimental and Clinical Pharmacology and Toxicology (DGPT)
Authors: Fox Louisa Christin , Seifert Roland 
Published: June 2024

AbstractBibliometric rankings of researchers are increasingly important for academic hiring and for making grant application decisions in the biomedical sciences. As a case study, we performed a comprehensive bibliometric analysis of German pharmacology and toxicology. The 42 members of the German Society for Experimental and Clinical Pharmacology and Toxicology (DGPT) represented in the German ‘best scientist’ ranking in biology and biochemistry on www.research.com for the year 2022 were analyzed according to various aspects. The scientist ranking on Research.com is based on the Hirsch Index (h-Index). In the comparatively small field of pharmacology, which accounts for only 4.2% of the scientists in the ranking on Research.com, there are only two women. This shows that female pharmacologists are highly underrepresented in elite pharmacology. To achieve a high h-Index, a pharmacologist must publish more papers than a biochemist or biologist. Furthermore, German elite pharmacology was compared in the three sub-societies of the DGPT. There are no significant differences between elite pharmacologists and toxicologists in terms of productivity. Two large German pharmacology schools (Günter Schultz and Franz Hofmann) are similar in all bibliometric parameters except for number of total publications. Age-specific factors were also defined for the analysis: ‘academic age’ and the quotient of the h-Index by ‘academic age’. Any given bibliometric parameter (or combination of parameters) yielded different ranking results. This became even more evident when additionally considering the highly popular and widely used Laborjournal ranking of top pharmacology and toxicology researchers with only very few DGPT members listed. We unmasked 7 types of publication patterns of pharmacologists, an age-dependent publication peak at around 55 years and different trajectories for high- and low-volume publishing pharmacologists. In the future, less emphasis should be paid to bibliometric parameters in academic hiring and grant decisions than to the authentic societal and scientific impact of the research. Bibliometric parameters are very arbitrary within a very large segment of pharmacologists. Studies according to the paradigm of this account should be made for other countries, other learned societies, and other scientific fields. The different cultures among related scientific fields must be considered in bibliometric analyses as exemplified here for pharmacology versus biochemistry. Conversely, the bibliometric similarities between pharmacology and toxicology show that both fields belong together and have a very similar culture.
Connective tissue disease-associated lung disease in children

Published: June 2024

AbstractConnective tissue diseases are a heterogeneous group of autoimmune diseases that can affect a variety of organ systems. Lung parenchymal involvement is an important contributor to morbidity and mortality in children with connective tissue disease. Connective tissue disease-associated lung disease in children often manifests as one of several radiologic-pathologic patterns of disease, with certain patterns having a propensity to occur in association with certain connective tissue diseases. In this article, key clinical, histopathologic, and computed tomography (CT) features of typical patterns of connective tissue disease-associated lung disease in children are reviewed, with an emphasis on radiologic-pathologic correlation, to improve recognition of these patterns of lung disease at CT and to empower the pediatric radiologist to more fully contribute to the care of pediatric patients with these conditions.

AbstractTreatment duration with checkpoint inhibitors must be optimized to prevent unjustified toxicity, but evidence for the management of cutaneous squamous cell carcinoma is lacking. A retrospective study was performed to evaluate the survival of patients with cutaneous squamous cell carcinoma (CSCC) who discontinued cemiplimab due to different causes and without progression. Among 95 patients with CSCC who received cemiplimab, 22 (23%) patients discontinued immunotherapy due to causes other than progression, such as comorbidities, toxicity, complete response or lack of compliance (group that discontinued before censoring [DBC]), then 73 patients had standard treatment scheduled (STS). The overall survival was 25.2 months (95% CI: 8.9–29.4) in STS group and 28.3 months (95% CI: 12.7–28.3) in the DBC group; deaths for all causes were 11/22 (50%) in the DBC group and 34/73 (46.6%) in the STS group (p = 0.32). 10/22 (45.4%) subjects died due to CSCC in the DBC after discontinuation and 34/73 (46.6%) in the STS group, and the difference between groups was not significant (p = 0.230). Duration of treatment was significantly lower in subjects with stable disease versus those with complete or partial response (16.9, 30.6 and 34.9 months, respectively; p = 0.004). Among the 22 STS patients, 12 received cemiplimab for less than 12 months (10 [83%] died) and 10 for at least 12 months (1 [10%] died). Our observation, finding no outcome difference between DBC and STS groups, suggests that ICI treatment after one year might expose patients to further treatment related events without efficacy advantages.

Abstract
Background
Although, immune checkpoint inhibitors (ICIs) have been widely applied in the therapy of malignant tumors, the efficacy and safety of ICIs in patients with tumors and pre-existing CAD, especially chronic coronary syndromes (CCS) or their risk factors (CRF), is not well identified.

Methods
This was a nationwide multicenter observational study that enrolled participants who diagnosed with solid tumors and received ICIs therapy. The main efficacy indicators were progression-free survival (PFS) and overall survival (OS), followed by objective response rate (ORR) and disease control rate (DCR). Safety was assessed by describing treatment-related adverse events (TRAEs) during ICIs therapy evaluated by the Common Terminology Criteria for Adverse Events 5.0 (CTCAE 5.0).

Results
In the current research, we retrospectively analyzed the data of 551 patients diagnosed with solid tumors and received ICIs therapy, and these patients were divided into CCS/CRF group and non-CCS/CRF group. Patients with CCS/CRF had more favorable PFS and OS than patients without CCS/CRF (P < 0.001) and the pre-existing CCS/CRF was a protective factor for survival. The ORR (51.8% vs. 39.1%) and DCR (95.8% vs. 89.2%) were higher in CCS/CRF group than in non-CCS/CRF group (P = 0.003, P = 0.006). In this study, there was no significant difference in treatment-related adverse events (TRAEs), including immune-related adverse events (irAEs), between the two groups.

Conclusions
We concluded that ICIs appear to have better efficacy in malignant solid tumor patients with pre-existing CCS/CRF and are not accompanied by more serious irAEs.

AbstractIntralesional corticosteroid injections are a first-line treatment for keloids; yet clinical treatment results are highly variable and often suboptimal. Variation in triamcinolone acetonide (TAC) biodistribution may be an important reason for the variable effects of TAC treatment in keloids. In this exploratory study we investigated the biodistribution of TAC in keloids and normal skin using different drug delivery techniques. Fluorescent-labeled TAC suspension was administered into keloids and normal skin with a hypodermic needle and an electronic pneumatic jet injector. TAC biodistribution was represented by the fluorescent TAC volume and 3D biodistribution shape of TAC, using a 3D-Fluorescence-Imaging Cryomicrotome System. Twenty-one keloid and nine normal skin samples were analyzed. With needle injections, the mean fluorescent TAC volumes were 990 µl ± 479 in keloids and 872 µl ± 227 in normal skin. With the jet injector, the mean fluorescent TAC volumes were 401 µl ± 252 in keloids and 249 µl ± 67 in normal skin. 3D biodistribution shapes of TAC were highly variable in keloids and normal skin. In conclusion, TAC biodistribution in keloids is highly variable for both needle and jet injection. This may partly explain the variable treatment effects of intralesional TAC in keloids. Future research is needed to confirm this preliminary finding and to optimize drug delivery in keloids.

Published: June 2024

AbstractFollicular cell suspension (FCS) transplantation is a novel surgical method for treating resistant stable vitiligo, whereas mini punch grafting is an established effective method for treating stable vitiligo. The combination of FCS and mini punch grafting is a better strategy for the treatment of resistant stable vitiligo. The aim of the study was to evaluate the efficacy of follicular cell suspension, mini punch grafting, and a combination of both techniques in the treatment of stable vitiligo. This prospective comparative study was conducted on 48 patients with stable vitiligo. They were divided into three equal groups, including group A (treated with follicular cell suspension), group B (treated with mini punch grafting), and group C (treated with the combination of both techniques). All patients were followed-up for six months for the assessment of their therapeutic response regarding clinical outcomes. By comparing the data of the three studied groups, we found that the difference in the degree of re-pigmentation after one and three months of treatment was not significant. However, the progress of re-pigmentation was significantly different after six months of treatment among the three studied groups (P = 0.027). Specifically, re-pigmentation was significantly better in group C than in groups A and B (P = 0.037 and 0.017, respectively), but it was not significantly different between groups A and B.

Published: June 2024

AbstractMycosis fungoides (MF) is the most common primary cutaneous T-cell lymphoma (CTCL) with its etiology not yet fully understood. Interleukin (IL)-35 is an inhibitory cytokine that belongs to the IL-12 family. Elevated IL-35 in the plasma and the tumor microenvironment increases tumorigenesis and indicates poor prognosis in different types of malignancies. The objective of this study is to estimate the expression levels of IL-35 in tissue and serum of MF patients versus healthy controls. This case-control study included 35 patients with patch, plaque, and tumor MF as well as 30 healthy controls. Patients were fully assessed, and serum samples and lesional skin biopsies were taken prior to starting treatment. The IL-35 levels were measured in both serum and tissue biopsies by ELISA technique. Both tissue and serum IL-35 levels were significantly higher in MF patients than in controls (P < 0.001) and tissue IL-35 was significantly higher than serum IL-35 in MF patients (P < 0.001). Tissue IL-35 was significantly higher in female patients and patients with recurrent MF compared to male patients and those without recurrent disease (P < 0.001). Since both tissue and serum IL-35 levels are increased in MF, IL-35 is suggested to have a possible role in MF pathogenesis. IL-35 can be a useful diagnostic marker for MF. Tissue IL-35 can also be an indicator of disease recurrence.

AbstractPost-acne erythema (PAE) is a bothering skin condition that emerges from inflammatory acne and persists after its resolution. It is characterized by telangiectasia and erythematous macules. the role of 1064-nm Nd: YAG when combined with low-dose isotretinoin in the acne erythema treatment. forty-eight PAE patients were involved in the study. They were divided into two groups; group (A) patients administering a low dose of oral isotretinoin (10 mg/day) and underwent a total of six two-week interval sessions of 1064 ND-YAG laser treatment, group (B) patients administering a low dose of oral isotretinoin (10 mg/day) only. All adverse effects experienced during the course of therapy were documented, and photos were taken before the start of the treatment and following the end of the treatment duration. Following the completion of the therapeutic intervention, a significant improvement in clinical condition was observed in both groups, with more improvement in group (A) compared to group (B) as evidenced by a notable improvement in the score on the Clinician Erythema Assessment Scale (CEAS) and also a significant decrease in the mean value of optical density of the erythema. combined 1064-nm Nd: YAG with low-dose isotretinoin may be an efficient and secure line in the PAE treatment. Also, the combined therapy had superior results when compared to low-dose isotretinoin alone.

Published: June 2024

AbstractEthanol is metabolized by alcohol dehydrogenase to acetaldehyde and induces cytochrome P450 2E1 (CYP2E1), which generates reactive oxygen species that cause inflammatory liver damage. Clomethiazole, a drug approved for alcohol withdrawal treatment (AWT) in some European countries, inhibits CYP2E1. We hypothesized that clomethiazole would lead to a faster reduction in oxidative stress, inflammatory cytokines, and liver enzymes compared to diazepam treatment. We analysed respective biomarkers in 50 patients undergoing AWT and 25 healthy individuals but found no statistical difference between the two medication groups over 3–5 days. Hence, our hypothesis was not confirmed during this observation period.

Abstract
Purpose
Infections are common complications in patients following liver transplantation (LTX). The early diagnosis and prognosis of these infections is an unmet medical need even when using routine biomarkers such as C-reactive protein (CRP) and procalcitonin (PCT). Therefore, new approaches are necessary.

Methods
In a prospective, observational pilot study, we monitored 30 consecutive patients daily between days 0 and 13 following LTX using the 29-mRNA host classifier IMX-BVN-3b that determine the likelihood of bacterial infections and viral infections. True infection status was determined using clinical adjudication. Results were compared to the accuracy of CRP and PCT for patients with and without bacterial infection due to clinical adjudication.

Results
Clinical adjudication confirmed bacterial infections in 10 and fungal infections in 2 patients. 20 patients stayed non-infected until day 13 post-LTX. IMX-BVN-3b bacterial scores were increased directly following LTX and decreased until day four in all patients. Bacterial IMX-BVN-3b scores detected bacterial infections in 9 out of 10 patients. PCT concentrations did not differ between patients with or without bacterial, whereas CRP was elevated in all patients with significantly higher levels in patients with bacterial infections.

Conclusion
The 29-mRNA host classifier IMX-BVN-3b identified bacterial infections in post-LTX patients and did so earlier than routine biomarkers. While our pilot study holds promise future studies will determine whether these classifiers may help to identify post-LTX infections earlier and improve patient management.

Abstract
Purpose
Systemic sclerosis (SSc) is a rare autoimmune disease associated with high morbidity and mortality. SSc treatment is still challenging, and evidence is scarce. In the last decades high-dose chemotherapy and autologous stem cell transplantation (HD-ASCT) has proven to be effective. However, treatment related morbidity and mortality (TRM) are high. We conducted a retrospective, single-center analysis of SSc patients following HD-ASCT focusing on TRM and risk factors.

Methods
32 patients who underwent HD-ASCT at our hospital between June 2000 and September 2020 were included. Clinical characteristics were evaluated based on chart review before and after HD-ASCT. Analyses focused on overall survival (OS), TRM, and response to HD-ASCT.

Results
Median OS was 81 months (range 0–243). Within one year, 20 of 32 (76.9%) patients responded to HD-ASCT. Overall, 6 patients (18.8%) died in the context of HD-ASCT. Patients with subjective response to HD-ASCT (p = 0.024) and those with shorter time to platelet engraftment (p = 0.047) had significantly longer OS. Impaired renal function, age at HD-ASCT ≥ 55, disease duration < 12 months, high Hematopoietic cell transplantation-specific comorbidity index (HCT-CI) and Charlton Comorbidity Index (CCI) scores were associated with higher TRM. Patients receiving conditioning chemotherapy with thiotepa needed longer time for neutrophil (p = 0.035) and platelet engraftment (p = 0.021).

Conclusion
This study confirms the efficacy of HD-ASCT for patients with SSc in a single center real-world setting. High TRM is still a challenge. However, TRM could be reduced by exclusion of high-risk patients and attention to prognostic parameters and scores as suggested in this study.
