Objective: This pilot case series investigated the feasibility and efficacy of an eight-week therapy program, combining nasally administered ketamine (0.5 mg/kg) with trauma-focused psychotherapy, for individuals with chronic, treatment-resistant post-traumatic stress disorder (PTSD)., Method: Three patients with chronic, treatment-resistant PTSD underwent the eight-week therapy program. Clinical assessments included the Clinician-Administered PTSD Scale for DSM-5 (CAPS-5) and the Hamilton Depression Rating Scale (HAMD) at baseline, post-assessment, and follow-up assessment, along with additional measures assessing other relevant symptoms and side effects., Results: The results demonstrated clinically relevant reductions in PTSD symptoms, indicated by a change in the CAPS-5 score at post-assessment ( M = -18.00; SE = 6.48) and follow-up assessment ( M = -25.33, SE = 5.58). Additionally, depressive symptoms showed notable improvement, with changes in HAMD scores at post-assessment ( M = -8.33, SE = 3.07) and follow-up assessment ( M = -9.00, SE = 3.77). Positive effects were also observed in anxiety reduction, decreased dissociations, and improvements in emotion regulation and disturbances of self-organization., Conclusions: Despite potential variations in clinical profiles among the patients, the therapy program demonstrated positive outcomes for all participants. Nasally administered ketamine was well tolerated and resulted in immediate symptom reduction in tension, anxiety, and common PTSD symptoms. However, to validate these findings and compare treatment efficacy, future randomized controlled trials are warranted, especially in comparison with trauma-focused therapy alone.

Background: Patients as active partners in their personal healthcare are key drivers to reducing costs, securing an effective usage of resources, and ensuring patient-provider satisfaction. Even though these benefits are acknowledged, a theoretical framework for the plethora of concepts used in this context, such as patient engagement, patient empowerment, or patient involvement is missing. Furthermore, the heterogeneous or synonymous usage of these terms leads to miscommunication, missing standard conceptual measures, and a deficiency in theory building and testing. Our objective is to show what the relationships and distinctions between concepts focussing on patients as active partners in their personal healthcare are., Methods: A systematic literature review was conducted to consolidate terms related to patients' having an active role in their healthcare. From 442 articles screened in PubMed, a final set of 17 papers was included. Any articles conceptualising or presenting relationships between the concepts were included. Information was synthesised, and contradictions were unravelled systematically. The concepts and their relationships are structured and represented by employing a concept map., Results: Patient-centredness is a concept dominantly influenced by health care providers and can enhance patients' competencies, attitudes, and behaviours towards their personal healthcare. Enabling patients to become more empowered can ultimately lead to their greater involvement and engagement. Fostering an active role of patients can also increase their adherence to the care pathway. In general, patient engagement seems to be the most conclusive and furthest developed concept in terms of turning patients into active partners in their personal healthcare., Conclusions: We plead for a stricter demarcation and therefore a terminological standardisation of the terms in the future to avoid further ambiguity and miscommunication. The concept map presents a basis for a uniform understanding and application of the concepts. Through a comprehensive understanding of the terms and their dimensions, relationships between the concepts can be utilised, measures can be derived, and theory building and testing can be enhanced, leading to better acceptance and utilisation of concepts in healthcare services. Furthermore, patient engagement is presented to be the most conclusive and furthest developed concept in the subject area., (© 2022. The Author(s).)

Mesenchymal stromal/stem cells (MSCs) are immature multipotent cells, which represent a rare population in the perivascular niche within nearly all tissues. The most abundant source to isolate MSCs is adipose tissue. Currently, perirenal adipose tissue is rarely described as the source of MSCs. MSCs were isolated from perirenal adipose tissue (prASCs) from patients undergoing tumor nephrectomies, cultured and characterized by flow cytometry and their differentiation potential into adipocytes, chondrocytes, osteoblasts and epithelial cells. Furthermore, prASCs were stimulated with lipopolysaccharide (LPS), lipoteichoic acid (LTA) or a mixture of cytokines (cytomix). In addition, prASC susceptibility to human cytomegalovirus (HCMV) was investigated. The expression of inflammatory readouts was estimated by qPCR and immunoassay. HCMV infection was analyzed by qPCR and immunostaining. Characterization of cultured prASCs shows the cells meet the criteria of MSCs and prASCs can undergo trilineage differentiation. Cultured prASCs can be induced to differentiate into epithelial cells, shown by cytokeratin 18 expression. Stimulation of prASCs with LPS or cytomix suggests the cells are capable of initiating an inflammation-like response upon stimulation with LPS or cytokines, whereas, LTA did not induce a significant effect on the readouts (ICAM-1, IL-6, TNFα, MCP-1 mRNA and IL-6 protein). HCMV broadly infects prASCs, showing a viral load dependent cytopathological effect (CPE). Our current study summarizes the isolation and culture of prASCs, clearly characterizes the cells, and demonstrates their immunomodulatory potential and high permissiveness for HCMV., Competing Interests: The authors declare no conflict of interest.

Background: Hybrid tumours of the salivary glands are rare neoplasms. They are composed of at least two different tumour entities located in the same topographic area and account for only 0.1% of all salivary gland tumours. The most common component is an adenoid cystic carcinoma. There are several possible forms of hybrid tumours, which are most commonly located in the parotid gland., Case Report: We report on a 59-year-old female, who presented with a lesion of the caruncula of the left sublingual gland. The biopsy showed an adenoid cystic carcinoma in combination with a salivary duct carcinoma. Treatment consisted of tumour resection, bilateral selective neck dissection and adjuvant radiotherapy. Histopathologically, at least 30% of the tumour mass was composed of a salivary duct carcinoma and 70% of an adenoid cystic carcinoma. At 58 months after treatment, the patient is alive without evidence of recurrent disease., Conclusion: To our knowledge, the presented case is the first description of a hybrid tumour of the sublingual gland. Furthermore, the post-therapeutic course is encouraging, as hybrid tumours of the salivary glands usually have a poor prognosis.
