Ornithine transcarbamylase deficiency (OTCD) is a metabolic and genetic disease caused by dysfunction of the hepatocytic urea cycle. To develop new drugs or therapies for OTCD, it is ideal to use models that are more closely related to human metabolism and pathology. Primary human hepatocytes (HHs) isolated from two patients (a 6-month-old boy and a 5-year-old girl) and a healthy donor were transplanted into host mice (hemi-, hetero-OTCD mice, and control mice, respectively). HHs were isolated from these mice and used for serial transplantation into the next host mouse or for in vitro experiments. Histological, biochemical, and enzyme activity analyses were performed. Cultured HHs were treated with ammonium chloride or therapeutic drugs. Replacement rates exceeded 80% after serial transplantation in both OTCD mice. These highly humanized OTCD mice showed characteristics similar to OTCD patients that included increased blood ammonia levels and urine orotic acid levels enhanced by allopurinol. Hemi-OTCD mice showed defects in OTC expression and significantly low enzymatic activities, while hetero-OTCD mice showed residual OTC expression and activities. A reduction in ammonium metabolism was observed in cultured HHs from OTCD mice, and treatment with the therapeutic drug reduced the ammonia levels in the culture medium. In conclusion, we established in vivo OTC mouse models with hemi- and hetero-patient HHs. HHs isolated from the mice were useful as an in vitro model of OTCD. These OTC models could be a source of valuable patient-derived hepatocytes that would enable large scale and reproducible experiments using the same donor.
When a newborn child requires neonatal intensive care, it is often the beginning of a journey of stress and worry for the parents. Such situations could cause difficulties in problem-solving and communication within the family and result in decreased family functioning. Studies have shown that nurse-led interventions in the form of Family Health Conversations promote family's well-being and functioning and strengthen their relationships. However, this model has not previous been used and evaluated with families who have a child in need of neonatal intensive care.

To describe parents' experiences of participating in Family Health Conversations after having a child in need of neonatal intensive care.

Family interviews were conducted with 12 families from three neonatal intensive care units in southern Sweden, six months after a Family Health Conversations intervention. Data were analysed using qualitative content analysis.

The parents experienced the Family Health Conversations as an opportunity to co-create a comprehensive picture of what had happened after their child was born. Parents shared their experiences of the Family Health Conversations in terms of feeling validated and strengthened as individuals, as a couple, and as a family. They found the conversations to be supportive to their well-being and to processing experiences and becoming equipped for the future. The parents reported that it was valuable to talk with conversational leaders who had knowledge in neonatal care and who thereby understood what the parents were talking about. This provided a different type of support compared with other conversational contacts.

These results highlight the importance of having an early onset of family conversations in order to help the parents to cope with their challenges and improve their well-being.

The aim of this study was to identify macrophage phenotypes in synovium and monocyte subsets in peripheral blood in C57BL/6 mice by destabilizing the medial meniscus (DMM), and the association of macrophage subsets with OA features. DMM, sham, and non-operated knees were histologically assessed between 1 and 56 days for macrophage polarization states by immunohistochemistry (IHC), cartilage damage, synovial thickening, and osteophytes (n = 9 per timepoint). read more Naive knees (n = 6) were used as controls. Monocyte and polarized synovial macrophage subsets were evaluated by flow cytometry. CD64 and CD206 levels on IHC were higher at early timepoints in DMM and sham knees compared to naive knees. iNOS labeling intensity was higher in DMM and sham knees than in naive knees from d3 onwards. CD163 expression was unaltered at all timepoints. Even though macrophage polarization profiles were similar in DMM and sham knees, only in DMM knees the presence of iNOS and CD206 associated with synovial thickness, and CD163 staining inversely correlated with osteophyte presence. At day 14, monocyte subset distribution was different in peripheral blood of DMM mice compared with sham mice. In conclusion, monocyte subsets in blood and synovial macrophage phenotypes vary after joint surgery. High levels of iNOS+ , CD163+ , and CD206+ cells are found in both destabilized and sham-operated knees, and coexistence with joint instability may be a requirement to initiate and exacerbate OA progression.Muscle atrophy and fatty infiltration have been directly correlated with higher rates of incomplete or failed healing following surgical repair of the rotator cuff. The purpose of this study was to evaluate clinically relevant functional and morphological changes in the supraspinatus muscle at various time points in this model of rotator cuff tendinopathy. Subacromial impingement was induced in 47, male C57BL/6 mice (total 94 limbs) by implantation of a metal clip in the subacromial space. Specimens were evaluated at 4, 6, and 12 weeks postoperatively. Gait analysis was used to measure various kinematic parameters. Supraspinatus muscle wet weight, histology, and quantitative reverse-transcription polymerase chain reaction analysis of genes related to muscle atrophy and adipogenesis were performed to characterize the structural, cellular, and molecular changes. Muscle atrophy and fatty infiltration was evident beginning at 6 weeks, with progression out to 12 weeks. Gait analysis identified significant functional changes in many aspects of gait and abnormal stance tracing as early as 4 weeks, verifying alterations in upper extremity function.
