    Abstract Objectives: Extracorporeal membrane oxygenation (ECMO) is recommended in adults with drowning-associated hypothermia and out-of-hospital cardiac arrest (OHCA). Our experience of managing a drowned 2-year-old girl with hypothermia (23°C) and cardiac arrest (58 min) prompted this summary using the CAse REport (CARE) guideline to address the question of optimal rewarming procedure in such patients.
    Design/patients: Following the CARE guideline, we identified 24 reports in the "PubMed database" describing children less than or equal to 6 years old with a temperature less than or equal to 28°C who had been rewarmed using conventional intensive care ± ECMO. Adding our patient, we were able to analyze a total of 57 cases.
    Main results: The two groups (ECMO vs non-ECMO) differed with respect to submersion time, pH and potassium but not age, temperature or duration of cardiac arrest. However, 44 of 44 in the ECMO group were pulseless on arrival versus eight of 13 in the non-ECMO group. Regarding survival, 12 of 13 children (92%) undergoing conventional rewarming survived compared with 18 of 44 children (41%) undergoing ECMO. Among survivors, 11 of 12 children (91%) in the conventional group and 14 of 18 (77%) in the ECMO group had favorable outcome. We failed to identify any correlation between "rewarming rate" and "outcome."
    Conclusions: In this summary analysis, we conclude that conventional therapy should be initiated for drowned children with OHCA. However, if this therapy does not result in return of spontaneous circulation, a discussion of withdrawal of intensive care might be prudent when core temperature has reached 34°C. We suggest further work is needed using an international registry.

    Abstract Reports on accidental intravenous epinephrine overdose in children are extremely rare, although medication errors in the management of pediatric anaphylaxis seem to be frequent. We report a case of a 12-year-old boy presenting with a long-lasting skin rash and dyspnea who was incorrectly diagnosed with early anaphylactic shock and was treated with 10-fold the recommended dose administered by the wrong route (intravenous instead of intramuscular). He reacted with acute loss of consciousness and acute cardiorespiratory failure due to arterial hypotension, ischemic heart failure, and severe pulmonary edema. He responded rapidly to mechanical ventilation, treatment with diuretics, and low-dose inotropes and recovered without sequelae. Despite this ultimately favorable outcome, we report this case to remind the scientific community that inadvertent and accidental epinephrine overdosing is probably an underrecognized event, which can result in potentially lethal complications. Heightening the awareness of the personnel, implementing safety precautions for the dosage and the route of administration, stocking of prefilled intramuscular dose syringes for emergency use in anaphylaxis and, ideally, introducing a standardized drug order form should reduce potential risks and facilitate proper and optimal treatment for all acutely ill children.

    Abstract Recruitment of Fc-receptor-bearing effector cells, such as natural killer (NK) cells, is a feature critical for the therapeutic success of antitumor antibodies and can be improved by the modifications of an antibody's Fc part. The various ligands of the activating immunoreceptor NKG2D, NKG2DL) are selectively expressed on malignant cells including leukemia. We here took advantage of the tumor-associated expression of NKG2DL for targeting leukemic cells by NKG2D-immunoglobulin G (IgG)1 fusion proteins containing modified Fc parts. Compared to NKG2D-Fc containing a wild-type Fc part (NKG2D-Fc-WT), our mutants (S239D/I332E and E233P/L234V/L235A/ΔG236/A327G/A330S) displayed highly enhanced (NKG2D-Fc-ADCC) and abrogated (NKG2D-Fc-KO) affinity to the NK cell Fc receptor, respectively. Functional analyses with allogenic as well as autologous NK cells and primary malignant cells of leukemia patients revealed that NKG2D-Fc-KO significantly reduced NK reactivity by blocking immunostimulatory NKG2D-NKG2DL interaction. NKG2D-Fc-WT already enhanced antileukemia reactivity by inducing antibody-dependent cellular cytotoxicity (ADCC) with NKG2D-Fc-ADCC mediating significantly stronger effects. Parallel application of NKG2D-Fc-ADCC with Rituximab caused additive effects in lymphoid leukemia. In line with the tumor-associated expression of NKG2DL, no NK cell ADCC against resting healthy blood cells was induced. Thus, NKG2D-Fc-ADCC potently enhances NK antileukemia reactivity despite the inevitable reduction of activating signals upon binding to NKG2DL and may constitute an attractive means for immunotherapy of leukemia.

    Abstract Cytotoxic T cells are important effectors for robust antitumor immune responses. However, tumor-infiltrating CD8 T cells are often functionally impaired. Insufficient antitumor activity of CD8 T cells can be due to a lack of costimulatory signals. NKG2D is such a costimulatory receptor on CD8 T cells that facilitates immunorecognition of stressed and malignant cells, promotes tumor rejection by NK and CD8 T cells and contributes to immunosurveillance of spontaneous malignancies. Previous reports suggested an involvement of NKG2D in establishing CD8 T cell-mediated antitumor memory. However, the significance of NKG2D for the generation and effector phase of memory CD8 T cell responses is largely unknown. To address these issues, we made use of a transgenic mouse model (H2-K(b)-MICA mice) where the human NKG2D ligand MICA is ubiquitously and constitutively expressed resulting in a severe dysfunction of NKG2D. Both, ovalbumin (OVA)-specific (H2-K(b)/OVA(257-264)) memory CD8 T cells arisen from the endogenous T cell pool and adoptively transferred OVA-specific OT-I memory cells were unable to control growth of an OVA-expressing lymphoma in H2-K(b)-MICA mice. While expansion of memory T cells in these mice on antigen challenge was not different from controls, CD8 memory T cells of H2-K(b)-MICA mice did not effectively eliminate tumor cells in vivo. Altogether, our data suggest that NKG2D has no major role in the generation and expansion of memory CD8 T cells, but rather substantially enhances the cytolytic effector responses of reactivated memory T cells and thereby contributes to an efficacious tumor rejection.

    Abstract Crambe meal (CM) is a potential dietary protein source for ruminant, but its effects in diets for lactating dairy cows remains unknown. We evaluated the effects of inclusion of the low-glucosinolates (GIs) CM (450 mg GIs/kg DM) in partial total mixed ration (pTMR) on performance, efficiency of nutrient utilization, and hepatic function of crossbred Holstein × Zebu and Jersey cows. Eight crossbred Holstein × Zebu cows and four Jersey cows were blocked by breed and days in milk, and randomly assigned in a replicated 4 × 4 Latin square design, and distributed in one of four isonitrogenous TMRs (130 g CP/kg DM): 0, 45, 90, and 135 g CM/kg DM pTMR. Crambe meal was included in pTMR replacing soybean meal (SBM) and ground corn grain (GCG). The pTMRs were offered ad libitum between 7:00 a.m. and 5:00 p.m. Cows were kept on pasture of Panicum maximum cv. Mombaça (90.4 g CP/kg DM) between 6:00 p.m. and 6:30 a.m. Pasture intake was measured from external and internal fecal excretion marker. Inclusion of CM did not affect (P ≤ 0.05) the DM intakes of pTMR and pasture, apparent total-tract digestibilities of organic matter, CP and NDF, ruminal outflow microbial protein, milk yield, milk composition, urinary N excretion, milk N efficiency, and level of plasm hepatic enzymes. The effects of CM inclusion in pTMR were independent of breed. Low-glucosinolates CM can be incorporated up to 135 g/kg DM in pTMR in replacement of SBM and GCG without affecting performance, efficiency of nutrient utilization, and hepatic function of crossbred Holstein × Zebu and Jersey cows.

    Abstract Chronic wounds, characterized by prolonged healing processes, pose a significant medical challenge with multifaceted aetiologies, including local and systemic factors. Here, it explores the complex pathogenesis of chronic wounds, emphasizing the disruption in the normal phases of wound healing, particularly the inflammatory phase, leading to an imbalance in extracellular matrix (ECM) dynamics and persistent inflammation. Senescent cell populations further contribute to impaired wound healing in chronic lesions. Traditional medical management focuses on addressing underlying causes, but many chronic wounds resist to conventional treatments, necessitating innovative approaches. Recent attention has turned to autologous orthobiologics, such as platelet-rich plasma (PRP), platelet-rich fibrin (PRF) and mesenchymal stem cells (MSCs), as potential regenerative interventions. These biologically derived materials, including bone marrow aspirate/concentrate (BMA/BMAC) and adipose tissue-derived stem cells (ADSCs), exhibit promising cytokine content and regenerative potential. MSCs, in particular, have emerged as key players in wound healing, influencing inflammation and promoting tissue regeneration. This paper reviews relevant scientific literature regarding basic science and brings real-world evidence regarding the use of orthobiologics in the treatment of chronic wounds, irrespective of aetiology. The discussion highlights the regenerative properties of PRP, PRF, BMA, BMAC and SVF, showcasing their potential to enhance wound healing. Despite advancements, further research is essential to elucidate the specific roles of each orthobiologic and determine optimal applications for different wound types. The conclusion underscores the evolving landscape in chronic wound management, with a call for more comprehensive studies to refine treatment strategies and maximize the benefits of regenerative medicine.
