To delineate the response of migrating chondrogenic progenitor cells (CPCs) that arose from the surface of mechanically injured articular cartilage to proinflammatory damage-associated-molecular-patterns (DAMPs).<br /><br /> Bovine CPCs and non-CPC chondrocytes isolated from either impacted or scratched articular cartilage were studied. Those 2 types of cells were treated with mitochondrial DAMPs (MTDs; 10 nM fMLF and 10 µg/mL CpG DNA), or 10 nM HMGB1, or 10 ng/mL IL-1b for 24 hours. At the end of experiments, conditioned media and cell lysates were collected for analysis of expression levels of matrix metalloproteinases (MMPs), chemokines, and cytokines that are associated with cartilage degeneration with Western blotting and quantitative polymerase chain reaction. The difference of expression levels was compared by Welch's <br /><br /> -test.<br /><br /> Our data indicated that HMGB1 and MTDs remarkably upregulated pro-MMP-13 expression in CPCs. Compared with non-CPCs, CPCs expressed significantly more baseline mRNAs of MMP-13, CXCL12, and IL-6. MTDs greatly increased the expression of MMP-13 and IL-6 in CPCs by over 100-fold (<br /><br /> &lt; 0.001). MTDs also significantly increased IL-8 expression in CPCs to a similar extent (<br /><br /> &lt; 0.001). However, when IL-1b was present, CPCs expressed less MMP-3 and active MMP-13 proteins as well as less CCL2 and IL-6 than did non-CPCs.<br /><br /> We concluded that CPCs were more sensitive than non-CPCs in response to DAMPs, especially MTDs. The proinflammatory nature of CPCs implied their critical role in the early phase of posttraumatic osteoarthritis development.<br /><br />We concluded that CPCs were more sensitive than non-CPCs in response to DAMPs, especially MTDs.

Patients &amp; methods Retrospective analysis of the US Flatiron database (ClinicalTrials.gov identifier NCT03896984). Results In the radium-223 cohort (n = 120) versus the alternative NHT cohort (n = 226), proportionally more patients had prior symptomatic skeletal events and bone-only metastases, and first-line NHT duration was shorter. Following second-line therapy, 49 versus 39% of patients received subsequent life-prolonging therapy; of these, 47 versus 76% received taxane. Median overall survival was 10.8 versus 11.2 months. Conclusion Real-world patients with mCRPC had similar median overall survival following second-line radium-223 or alternative NHT after first-line NHT. Many patients received subsequent therapy, with less taxane use after radium-223.<br /><br /> Various graft materials have been used to repair nasoseptal perforation, but there is no standardized treatment method. The anterior maxillary sinus wall is flattened in appearance and can be easily obtained in a sufficient amount for a large-sized nasoseptal perforation.<br /><br /> The aim of this study is to determine whether the anterior maxillary sinus wall is suitable as an interpositional graft in the surgical repair of septal or nasoseptal perforation.<br /><br /> This is a retrospective review of 21 patients who underwent repair of nasoseptal perforation using anterior maxillary sinus wall as an interpositional graft. The etiology<br /><br /> pre- and post-operative NOSE and GBI score, and perforation size were reviewed. The surgical outcome was considered successful if total closure was achieved after postoperative follow-up.<br /><br /> 19 of the 21 perforations were successfully repaired with anterior maxillary sinus wall. Failure of the repair was found in 2 patients. Causal etiology of perforation was previous septoplasty in 10 patients, and electrocautery in 1 case, but not identified in 10 cases. The largest size was 2.7 × 2.2 cm. The most common symptoms were epistaxis, crusting, and nasal obstruction. Closure of septal perforation resulted in improved subjective symptoms and quality of life which were evaluated with NOSE and GBI score.<br /><br /> Anterior maxillary sinus wall as interpositional graft between mucoperichondrial flaps can be used to reliably repair nasoseptal perforations.<br /><br />Anterior maxillary sinus wall as interpositional graft between mucoperichondrial flaps can be used to reliably repair nasoseptal perforations.<br /><br /> Furlow double-opposing Z-plasty (DOZ) lengthens the soft palate; however, this lengthening is achieved at the expense of increased mucosal flap tension. Thus, its use is limited in patients with severe tension applied on mucosal flap after DOZ. In this study, DOZ was combined with a buccal fat pad (BFP) flap to maximize palatal lengthening and muscle repositioning.<br /><br /> This study included patients who underwent surgical correction for velopharyngeal insufficiency between December 2016 and February 2019. Patients with more than moderate degree hypernasality following primary palatoplasty were included in the study. Patients younger than 4 years of age, those with a submucous cleft palate, or syndromic patients were excluded. Speech outcomes were investigated for those who underwent DOZ only (DOZ group, n = 17) and those in whom a BFP was used (BFP group, n = 15) pre- and postoperatively. The velopharyngeal gaps between the uvula and pharyngeal wall were measured before and immediately after surgery to estimate the palatal length.<br /><br /> Most patients who received a BFP showed improvement in hypernasality. However, the hypernasality of the DOZ group was more severe than that of the BFP group (p = 0.023). The extent of palatal lengthening was 4.4 ± 1.7 mm and 7.5 ± 2.1 mm in the DOZ and BFP groups, respectively (p = 0.001).<br /><br /> BFPs reduced the tension of the DOZ mucosal flap and maximized palatal lengthening and muscle repositioning. They promoted velopharyngeal closure in patients with moderate and moderate-to-severe velopharyngeal insufficiency. Hence, our method improves the surgical outcomes of patients with velopharyngeal insufficiency after primary palatoplasty.<br /><br />BFPs reduced the tension of the DOZ mucosal flap and maximized palatal lengthening and muscle repositioning.

Hospitalisation often prioritises clinical care activities at the expense of age-appropriate sleep. Nurses and the wider healthcare team contribute to this paradox. However, through conscious practice and partnering with mothers, nurses are able to enact change and promote sleep.<br /><br /> To adopt, adapt or contextualise existing guidelines to develop an evidence-based practice guideline to promote sleep-friendly ward environments and routines facilitated by nurses, and in partnership with mothers.<br /><br /> A six-step methodology for guideline adaptation was followed, as recommended by the South African Guidelines Excellence project (1) existing guidelines and protocols were identified and (2) appraised using the AGREE II instrument; (3) an evidence base was developed; (4) recommendations were modified, (5) assigned levels of evidence an, which is amplified by poor sleep in a hospital. Nurses have the opportunity to promote sleep during hospitalisation by implementing this African-centric guideline in partnership with mothers.<br /><br /> In paediatric wards, children are often reluctant to receive medication from nurses and eventually it is given by the parents. It is a common practice for nurses to hand the medication to mothers to give to their children, However, it is an 'informal' practice and lacks evidence-based guidelines.<br /><br /> To develop a contextualised and adapted evidence-based guideline to support nurses to partner with mothers/carers so that they can safely give oral medication to their hospitalised child under the supervision of a competent nurse.<br /><br /> Existing relevant guidelines were identified through searches of bibliographic databases and websites. The AGREE II Appraisal of Guidelines for Research and Evaluation II instrument was used to appraise the quality of the identified sources. The process of guideline adaptation recommended by the South African Guidelines Excellence project was followed, and a list of adapted recommendations was developed, aligned with the legislative and regulatory frameworks for nursing in South Africa. Accessible end user documentation was developed.<br /><br /> Six sources were screened and three sources were found to be eligible and were subjected to full appraisal. Two guidelines and one policy document were identified as suitable for adaptation. Expert consultation confirmed that the resulting adapted guideline was sound, easy to understand, and well presented for the target audience.<br /><br /> This process successfully led to the development of a modified evidence-based practice guideline to enable nurses to partner with mothers/caregivers in safely giving oral medication to their hospitalised child in lower-resourced African settings.<br /><br />This process successfully led to the development of a modified evidence-based practice guideline to enable nurses to partner with mothers/caregivers in safely giving oral medication to their hospitalised child in lower-resourced African settings.<br /><br /> Preeclampsia is one of the causes of maternal deaths and is also responsible for complications such as premature births worldwide. In South Africa, hypertensive disorders cause 14% of all maternal deaths. Evidence indicates that it may be beneficial to empower women to monitor their blood pressure (BP) in the comfort of their homes.<br /><br /> The purpose of this study was to explore and describe preeclampsia patients' knowledge and attitudes towards the self-monitoring of their BP.<br /><br /> An exploratory, descriptive and contextual qualitative research study was conducted. Fourteen preeclampsia patients were purposively sampled and participated in the study. In-depth semi-structured interviews were used to collect data. Data were analysed using the thematic analytic approach.<br /><br /> The knowledge and attitudes towards the self-monitoring of blood pressure (SMBP) were explored. Four themes emerged, namely understanding of hypertension disorders during pregnancy, openness on self-monitoring at home, its hindrances and benefits. The participants portrayed limited understanding and knowledge of preeclampsia, yet they had positive attitudes towards monitoring BP themselves and were open and willing to do self-monitoring at home.<br /><br /> The use of SMBP may relieve overcrowding in public healthcare institutions. Encouraging patients to participate in self-monitoring could promote active participation and a positive outlook on their pregnancies.
