The aim of this study was to develop a third-generation modular mandible endoprosthesis that would experience less stress concentration at its stems compared to earlier generations, thereby minimizing micromotion and achieving long-term stability. In this three-piece modular design, different degrees of movement were incorporated between the endoprosthesis module interfaces. It was hypothesized that this unique feature would minimize stress concentration at the stems and hence promote osseointegration during the early phase of implantation. The endoprosthesis system was made of commercially pure grade 4 titanium, machined and surface-treated, then sterilized and implanted in segmental mandible defects of nine Macaca fascicularis. Clinical, radiological, histological, and histomorphometric evaluations were performed 4 months post-implantation. The endoprosthesis systems with a degree of movement incorporated, exhibited superior performance compared to the rigid system 30.9-34.8 times higher percentage bone-implant contact (P less then 0.0001) and 3.4-4.1 times higher percentage bone area (P less then 0.0001), with osseointegration noted at the posterior stems. However, fibrous tissue encapsulation was noted around the majority of the anterior stems in all groups. Although the degree of movement was favourable for improving bone healing and stability of the endoprosthesis system, more work needs to be done to investigate other strategies to further reduce loading on the endoprosthesis to achieve predictable osseointegration at the stems.The purpose of this study was to assess the outcomes of patients with advanced recurrent nasopharyngeal carcinoma (rNPC) and radiation-induced sarcoma of the head and neck (RISHN) who underwent en bloc resection and reconstruction. Fifty-two patients with advanced rNPC (n=36) and RISHN (n=16) underwent en bloc resection and reconstruction with an extended lower vertical trapezius island myocutaneous flap (TIMF). En bloc resection of the tumour (including craniomaxillofacial resections and neck resections) and major defect restoration was successful in all patients. TIMF survival was 92.3%. Postoperative mild hemiplegia occurred in one patient with rNPC. In total, 20 patients (55.5%) in the rNPC group and seven (43.8%) in the RISHN group recovered with no signs of disease at follow-up. No statistically significant difference in recovery status was observed between the rNPC and RISHN groups. En bloc resection of the tumour, including dissection of the carotid artery, ensured microscopic clearance of the disease; this is a viable treatment option for patients with advanced rNPC or RISHN without distant metastasis. SC75741 datasheet The extended vertical lower TIMF is a large, straightforward, and reliable flap for repairing the resultant major defects in the craniomaxillofacial or neck region.

Readmission after percutaneous coronary intervention is common in the early postdischarge period, often linked to limited opportunity for education and preparation for self-care. Attending a nurse-led clinic within 30 dafter discharge has the potential to enhance health outcomes.

The aim of the study was to synthesise the available literature on the effectiveness of nurse-led clinics, during early discharge (up to 30 d), for patients who have undergone percutaneous coronary intervention.

A systematic review of randomised and quasi-randomised controlled trials was undertaken.

The databases included PubMed, OVID, CINAHL, EMBASE, the Cochrane Library, SCOPUS, and ProQuest.

Databases were searched up to November 2018. Two independent reviewers assessed studies using the Cochrane risk-of-bias tool.

Of 2970 articles screened, only four studies, representing 244 participants, met the review inclusion criteria. Three of these studies had low to moderate risk of bias, with the other study unclear. Interventer percutaneous coronary intervention on outcomes for patients and health services. More robust research with sufficiently powered sample sizes and clearly defined interventions, comparison groups, and outcomes is recommended to determine effectiveness of nurse-led clinics in the early discharge period.

Long duration of untreated psychosis (DUP) has been linked with more severe psychotic and negative symptoms. However, it is uncertain which specific psychotic and negative domains that are affected over time and if these are stable over the course of illness.

To examine whether DUP is associated with psychotic and negative symptoms measured longitudinally up to 10years after initial assessment.

Psychopathology of participants from the OPUS I trial, aged 18-45years with a baseline ICD-10 schizophrenia spectrum diagnosis, excluding schizotypal disorder (468 participants left), was assessed at baseline and 2, 5 and 10years after initial assessment. The associations between DUP and domains of positive and negative symptoms were calculated using linear regression analysis.

Longer DUP was significantly associated with the severity of hallucinations, delusions and anhedonia-asociality at baseline. Longer DUP remained significantly associated with hallucinations, delusions and anhedonia-asociality after 2years. DUP was significantly associated with hallucinations, delusions, avolition-apathy and anhedonia-asociality after 5years. Longer DUP was still significantly associated with hallucinations and delusions but not with any of the negative symptom subdomains after 10years. Results were not substantially changed after adjusting for treatment with antipsychotic medication at each point in time.

We demonstrated associations between DUP and the severity of hallucinations and delusions which persist after at least 10years of follow-up and an association between longer DUP and anhedonia-asociality which persist until 5years of follow-up. Further, DUP was associated with avolition-apathy after 5years.
