An integrated deep learning and Bayesian computational method-based quantification of angiogenesis in the chick embryo model.

Singh Gurmeet G, Paik Pradip P

Angiogenesis is the process of the formation of new blood vessels from existing vessels, and it sits directly at the intersection of normal physiology and multiple diseases. Normal physiological activities like embryonic development and tissue homoeostasis require precise regulation. Diseased conditions occur when angiogenesis is dysregulated, which drives tumour growth when excessive or leads to diabetic retinopathy-like conditions when insufficient. Researchers are working on therapeutic interventions, and mechanistic studies have made reliable angiogenesis screening essential. Cell-based assays suffer from limited direct physiological relevance, and animal-based models are complex but expensive and raise ethical questions. In this work, we have developed an integrated deep-learning method for the quantitative estimation of angiogenesis from chick embryo-based experimental data. The chick embryo-based yolk sac membrane model (YSM) provides a complex environment for animal models without the cost of other studies. The model developed here offers a direct optical window providing detailed time-based information. The lack of available image analysis tools capable of handling these specific optical characteristics has hindered this assay for a long time. Subsequently, we have designed a pipeline for angiogenesis image analysis tailored to the YSM assay. Here, we have integrated standard image processing (channel separation and CLAHE enhancement) with deep learning and a Bayesian hierarchical Gompertz Gaussian process model for probabilistic vessel length forecasting. This is validated pharmacologically against the VEGF, anti-VEGF antibody, and hydrocortisone treatment groups. Analysis tools tailored for this assay have not been well reported as the YSM assay has a low signal-to-background ratio (red vessels against a yellow background), which has challenged experienced researchers.

Hydrocortisone Use for Septic Shock in Patients With CKD.

Dhamelia Parth P, Abeyagunawardene Hashane H, Kore Rajshekhar A RA, Raghavan Deepa D et al.

Patients with chronic kidney disease (CKD) are at higher risk of septic shock and mortality than the general population. Although hydrocortisone is often used as an adjuvant therapy for septic shock in the general population to improve clinical outcomes, its effectiveness in patients with CKD remains understudied. We identified a retrospective cohort of patients within TriNetX US collaborative database diagnosed with nondialysis CKD between November 1, 2010 and October 31, 2025 who also developed septic shock. Outcomes of interest within 90 days included all-cause mortality, major adverse kidney events (MAKE) without persistent kidney dysfunction, major adverse cardiovascular or cerebrovascular events (MACCE), mechanical ventilation, hyperglycemia, reinfections, and delirium. Survival analyses and multivariable Cox proportional hazard models were performed. One to 1, we propensity-score matched 13,141 CKD patients with sepsis treated with hydrocortisone with 13,141 CKD patients with sepsis not treated with hydrocortisone. Our cohort had a mean age of 70 ± 12 years and was 46% female, 21% African American, and 5% Hispanic. Most patients had hypertension (95%), were diabetic (63%), and had ischemic heart disease (68%). Mean serum creatinine concentration was 2.3 ± 2.7 mg/dl, mean lactate concentration was 3 mmol/l, and 25% of patients required mechanical ventilation. In this propensity-score matched analysis, more patients died in the group given hydrocortisone than in the group not given hydrocortisone (4263 [32.4%] vs. 3654 [27.8%]) with adjusted hazard ratio (HR) 1.31 (95% confidence interval [CI]: 1.25-1.36). Hydrocortisone group had higher risk of MAKE HR 1.08 (95% CI: 1.05-1.12), MACCE HR 1.19 (95% CI: 1.15-1.24), and mechanical ventilation HR 1.34 (95% CI: 1.27-1.41) but lower reinfections HR 0.88 (95% CI: 0.85-0.91) and no differences in hyperglycemia HR 1.04 (95% CI: 1.00-1.07) and delirium HR 1.07 (95% CI: 1.00-1.14). In this large, national, multicenter retrospective cohort of patients with CKD and septic shock, use of hydrocortisone was associated with increased risk of mortality, cardiorenal, and pulmonary outcomes, but reduced risk of reinfections. These findings warrant more research to rigorously evaluate the effects of hydrocortisone use in septic shock for this high-risk population.

The cell-mediated adaptive immune response to herpes simplex virus type 1 encephalitis: mechanisms and clinical implications.

Osborne Louise L, Dunai Cordelia C, Huang Yun Y, Egbe Franklyn N FN et al.

Herpes simplex virus (HSV) encephalitis is the most frequent cause of sporadic encephalitis globally. Despite the emergence of the antiviral drug aciclovir curtailing mortality, this disease remains a clinical challenge due to its rapid progression and associated neurological sequelae; indicating the urgent requirement for adjunctive neuroprotective treatment options. Recent studies using both human samples and murine models have highlighted how cell mediated immune cells including CD8+, CD4+ and brain tissue-resident memory T cells have the capacity to act as a 'double-edged sword'; both serving to protect the host against HSV encephalitis, but also increasing neuroglial injury by inflammation. Factors which impair cell-mediated immunity may predispose individuals to herpes simplex encephalitis, including defects in viral immune evasion strategies (infected cell protein 47, UL13 kinase), host genetic pre-disposition (toll-like receptor 3 deficiency, lymphotoxin-α deficiency, Rel mutations) and external factors such as stress. Additionally, there is a particular need for clinical vigilance for patients on immunosuppressive treatments which impair cell-mediated immunity, including azathioprine, hydroxychloroquine and methotrexate. Conversely, understanding these molecular mechanisms may provide new insights into the use of immunomodulatory strategies including anakinra, tocilizumab, and the implementation of targeted vaccination. This review summarises the current state of knowledge of how an impaired cell-mediated immune response could promote herpes simplex virus encephalitis, followed by an exploration of the clinical applications and therapeutic interventions which could viably be implemented to ameliorate immune-mediated tissue injury.

Tryptanthrin Nanoliposomal Lotion as a Corticosteroid-Free Strategy for Safe and Effective Treatment of Atopic Dermatitis.

Song Yo Han YH, Na Young-Guk YG, Yoon Moon Sup MS, Kim Da-Eun DE et al.

Atopic dermatitis is a chronic inflammatory skin disease characterized by dry skin, itching, and recurrent eczematous lesions. Although current therapeutic strategies are effective, their use is often limited due to adverse effects. Therefore, the development of safer and more effective alternatives is required. Tryptanthrin is a yellow-gold alkaloid compound with anti-atopic and various pharmacological activities. However, its poor aqueous solubility results in low topical bioavailability. A tryptanthrin-loaded liposomal lotion was developed using a design of experiments approach to improve topical delivery. The optimized formulation showed enhanced physicochemical stability and moisturizing properties, as well as improved drug release compared to free tryptanthrin. In human keratinocyte cells, the liposomal lotion exhibited lower cytotoxicity than the free tryptanthrin and demonstrated higher skin residual. In the DNCB-induced atopic dermatitis mouse model, the tryptanthrin-loaded liposomal lotion produced therapeutic effects comparable to or greater than those of 1.0% hydrocortisone, without inducing adverse effects such as skin atrophy. Overall, the tryptanthrin-loaded liposomal lotion is presented as a promising and safe strategy for the topical treatment of atopic dermatitis.

Tofacitinib as Rescue Therapy in Steroid-Refractory Acute Severe Ulcerative Colitis: A Retrospective Cohort Study with Observations on Cytomegalovirus Coinfection.

Banerjee Subhadeep S, Yadav Dawesh D, Gupta Anand A, Kumar Ujjwal U et al.

Acute severe ulcerative colitis (ASUC) is a severe and potentially life-threatening condition in which one-third of patients are refractory to intravenous corticosteroids. Established rescue therapies--infliximab and cyclosporine--are limited by cost, administration constraints, and toxicity. Tofacitinib, an oral Janus kinase (JAK) inhibitor, possesses pharmacokinetic and mechanistic properties that may be advantageous in the inpatient setting. This study was conducted to assess the short-term efficacy and safety of tofacitinib as rescue therapy in steroid-refractory ASUC and to identify clinical predictors of treatment failure. We conducted a retrospective cohort analysis of all patients with ASUC admitted to our tertiary gastroenterology unit between March 2023 and August 2025. ASUC was defined per Truelove and Witts' criteria. Patients who failed to respond to intravenous hydrocortisone by Day 3 and who could not receive infliximab (due to cost or contraindication) were initiated on tofacitinib (10 mg thrice daily for 3 days, followed by 10 mg twice daily). The primary outcome was clinical response by Day 5-7, defined as a reduction in Mayo score of ≥3 points (≥30% from baseline) with an absolute rectal bleeding sub-score of 0-1. Secondary outcomes included non-response rate, adverse events, and the impact of colonic cytomegalovirus (CMV) DNA burden on treatment response. Ten consecutive patients with steroid-refractory ASUC received tofacitinib rescue therapy. The mean age was 29.6 ± 9.1 years; 60% were male. Seven patients (70%) achieved clinical response within 5-7 days. Three patients (30%) failed to respond and required alternative rescue therapy or surgical consultation. CMV DNA was detected in the colonic tissue of four patients; both patients with high viral loads (>50,000 copies/mL) failed to respond to tofacitinib despite concurrent antiviral therapy. Adverse events were minimal; one patient developed bicytopenia of uncertain attribution. Tofacitinib demonstrated a 70% short-term clinical response rate in steroid-refractory ASUC, with an acceptable safety profile. Higher colonic CMV DNA appeared to be associated with a lower likelihood of clinical response; however, this observation requires validation with further research. Tofacitinib represents a viable, cost-effective rescue option, particularly in resource-limited settings or when conventional biologics are contraindicated. Prospective comparative studies are needed to define its optimal positioning within ASUC treatment algorithms.

Impact of Peripheral Rabbit Anti-Thymocyte Globulin Without Heparin and Hydrocortisone Additives on Local Infusion Reactions.

Borges Leanna L, Conrath Meagan M, O'Sullivan David M DM, Marti Kristen K

Rabbit anti-thymocyte globulin (rATG) is indicated for induction immunosuppression therapy in renal transplant recipients. Heparin and hydrocortisone are standardly added to peripheral rATG preparations to reduce the incidence of local infusion reactions. In March 2023, this institution removed heparin and hydrocortisone additives in peripheral rATG preparations to avoid medication waste in the setting of drug shortages. The purpose of this study was to compare the incidence of local infusion reactions in renal transplant recipients receiving peripheral rATG with and without additives. This was a single-center, retrospective, pre- and post-implementation cohort study of adult renal transplant recipients. Patients were included if they were ≥18 years of age, received rATG through a peripheral line, and received a renal transplant between November 1, 2022 and July 12, 2023, inclusive. The primary outcome was the incidence of local infusion reactions. Descriptive statistics were used to report baseline demographics and a Fisher's exact test was used to compare rates of local infusion reactions in the additives and no additives groups. A total of 261 peripheral rATG doses were included in the analysis. The baseline characteristics were similar between the two groups. Of the 261 rATG infusions, 120 infusions included heparin and hydrocortisone in the preparation, while 141 of the infusions did not contain additives. The difference between groups in occurrence of local infusion reactions was not statistically significant. Local infusion reactions were reported during ten (8.3%) rATG infusions with additives compared to eight (5.7%) rATG infusions without additives (P = .398). Renal transplant recipients receiving rATG induction therapy without heparin and hydrocortisone additives via peripheral infusion had a similar incidence of local infusion reactions compared to those with additives. Additional studies are needed to substantiate these findings.
