    Cicatricial eyebrow loss that occurs after trauma or burns considerably reduces a person’s self-confidence. Several methods, either surgical or nonsurgical, have been defined to reconstruct eyebrows. find more This study focused on eyebrow restoration using the atraumatic follicular unit extraction (FUE) technique in patients and emphasized certain details that should be considered during the treatment process. In this study, we discussed the management of 18 cases using this technique and their outcomes with respect to published literature.

    This study examined eyebrow restoration performed using a modified FUE technique in 18 patients who had cicatricial eyebrow loss due to trauma, excised congenital giant nevus, or burns. Moreover, special methods, including platelet-rich plasma, microneedling, steroid injections, and fat grafting, were used in each patient to increase the odds of graft survival.

    Aesthetically and functionally satisfactory outcomes were observed along with the appropriate orientation and symmetry of the eyebrows in all patients’ follow-ups. Moreover, patients exhibited increased self-confidence, and the quality of skin, particularly in the transplantation area, was improved. There was no complication either in the recipient or donor site.

    Eyebrow restoration using the atraumatic FUE technique should be considered as the first treatment option in cases with cicatricial eyebrow loss as long as an appropriate evaluation and treatment method is followed for each patient.

We previously developed a multiphasic 3D-bioplotted osteochondral scaffold design that can drive site-specific tissue formation when seeded with adipose-derived stem cells (ASC). The objective of this study was to evaluate this scaffold in a large animal model. Osteochondral defects were generated in the trochlear groove of Yucatan minipigs and repaired with scaffolds that either contained or lacked an electrospun tidemark and were either unseeded or seeded with ASC. Implants were monitored via computed tomography (CT) over the course of 4 months of in vivo implantation and compared to both open lesions and autologous explants. ICRS II evaluation indicated that defects with ASC-seeded scaffolds had healing that most closely resembled the aulogous explant. Scaffold-facilitated subchondral bone repair mimicked the structure of native bone tissue, but cartilage matrix staining was not apparent within the scaffold. The open lesions had the highest volumetric infill detected using CT analysis (p less then  0.05), but the repair tissue was largely disorganized. The acellular scaffold without a tidemark had significantly more volumetric filling than either the acellular or ASC seeded groups containing a tidemark (p less then  0.05), suggesting that the tidemark limited cell infiltration into the cartilage portion of the scaffold. Overall, scaffold groups repaired the defect more successfully than an open lesion but achieved limited repair in the cartilage region. With further optimization, this approach holds potential to treat focal cartilage lesions in a highly personalized manner using a human patient’s own ASC cells.

    To investigate different baseline characteristics, clinical indications, repeat retinopexy rate, and 6-month detachment rate of primary laser retinopexy across different ethnicities.

    Retrospective, single-centre, consecutive comparative study, looking at all patients who had primary laser retinopexy between January 2017 and 2020. Multivariate Cox survival and binary logistic regression (reporting odds ratio) analyses were performed to investigate differences between ethnicities with age, gender, operator level (vitreoretinal or general ophthalmologist) and high myopia status (≤-6.0Dioptres) as covariates.

    We report on 812 patients in three ethnicities Black , South Asian and White with overall 6-month detachment rate of 31 (3.8%). Rate for subsequent retinopexies was Black 12 (17.4%), SA 15 (9.6%) and White 131 (22.3%), p=0.002. Multivariate Cox survival regression analysis found no difference in detachment rate between ethnicities influence these variations and may help to allow for more targeted health care.

    We demonstrate a significant difference in baseline characteristics, retinal tear morphology and treatment course between the ethnic groups. Further studies are necessary to investigate the genetic and biological differences that may influence these variations and may help to allow for more targeted health care.MYSM1 is a chromatin-binding protein, widely investigated for its functions in haematopoiesis in human and mouse; however, its role in haematologic malignancies remains unexplored. Here, we investigate the cross-talk between MYSM1 and oncogenic cMYC in the transcriptional regulation of genes encoding ribosomal proteins, and the implications of these mechanisms for cMYC-driven carcinogenesis. We demonstrate that in cMYC-driven B cell lymphoma in mouse models, MYSM1-loss represses ribosomal protein gene expression and protein synthesis. Importantly, the loss of MYSM1 also strongly inhibits cMYC oncogenic activity and protects against B cell lymphoma onset and progression in the mouse models. This advances the understanding of the molecular and transcriptional mechanisms of lymphomagenesis, and suggests MYSM1 as a possible drug target for cMYC-driven malignancies.

    Direct oral anticoagulants (DOACs) may increase the risk of gastrointestinal (GI) bleeding in patients with atrial fibrillation (AF) and GI cancer compared with vitamin K antagonists (VKA).

    We conducted a Danish nationwide cohort study comparing the bleeding risk associated with DOAC versus VKA in patients with AF and GI cancer. We calculated crude bleeding rates per 100 person-years (PYs) for GI and major bleeding. We then compared rates of bleeding at 1year after initial oral anticoagulation filled prescription by treatment regimen using inverse probability of treatment weighting and Cox regression.

    The unweighted study population included 1476 AF patients with GI cancer (41.6% women, median age 78years) initiating a DOAC and 652 initiating a VKA. One-year risk of GI bleeding was 5.0% in the DOAC group and 4.7% in the VKA group with a corresponding weighted hazard ratio (HR) of 0.95 (95% confidence interval 0.63, 1.45). For patients with active cancer, weighted GI bleeding rates were slightly higher in both the VKA and DOAC group, and the weighted HR was 1.
