Online ahead of print. ABSTRACT BACKGROUND: The number of minimally invasive cosmetic procedures has steadily increased every year. In the last decade, the rates of filler injection reactions have also increased. This study presents our experience in the management and treatment of permanent filler complications to the lips. Undoubtedly, in these adverse reactions, the lips are the hallmark that most stigmatizes an unnatural look of the face. METHODS: One hundred and eighty-one patients (168 female and 13 male) with permanent filler complications to the lips were treated from September of 2009 to September of 2019 at the University Hospital of Modena. One hundred and thirty-five patients underwent intralesional laser treatment (ILT). Forty-six patients underwent a stab incision and drainage and 10 of these patients had solid and cal cified nodules and therefore underwent a combined technique. Thirty-three patients underwent further cosmetic procedures. RESULTS: In 95% of patients there was a clinical improvement of which complete resolution in 38.7% and partial improvement in 34.2% of cases. Nine patients stopped the treatment because they were not satisfied. No patient was considered to have worsened after the treatment. Thirty-three patients underwent further treatments. CONCLUSIONS: A systematic combined approach between antibiotic therapy and treatments (ILT and a stab incision) represents the best therapeutic approach in dealing with permanent fillers complications to the lips. This treatment modality allows both the removal of the foreign material and the inflammatory reaction with low morbidity and little cosmetic disfigurement. Further cosmetic procedures may be applied to improve aesthetic appearance once most of the non-resorbable substance has been removed.

Knockdown of circular RNA hsa_circ_0062270 suppresses the progression of melanoma via downregulation of CDC45

xlomafota13 shared this article with you from Inoreader Knockdown of circular RNA hsa_circ_0062270 suppresses the progression of melanoma via downregulation of CDC45 Via Cellular and Molecular Biology Histol Histopathol. 2021 Dec 21:18412. doi: 10.14670/HH-18-412. Online ahead of print. ABSTRACT BACKGROUND: Although systemic therapies for melanoma have been improved, the 5-year survival rate of this aggressive cancer remains poor. It has been shown that hsa_circ_0062270 was upregulated in patients with melanoma. However, the relevant mechanism of hsa_circ_0062270 in the progression of melanoma remains unclear. METHODS: The CCK-8, EdU staining, flow cytometry, and transwell assays were used to determine the viability, proliferation, apoptosis and invasion in melanoma cells. An in vivo animal study was performed finally. RESULTS: The level of hsa_circ_0062270 was significantly upregulated in melanoma cells. In addition, hsa_circ_0062270 knockdown markedly inhibited the viability, proliferation, invasion and promoted the apoptosis of melanoma cells. Cell division cycle protein 45 (CDC45) is the host gene of hsa_circ_0062270 , and downregulation of hsa_circ_0062270 notably decreased the expression of CDC45 in melanoma cells. Rescue assays confirmed that hsa_circ_0062270 regulated the growth of melanoma cells through CDC45. Moreover, RIP analysis showed that hsa_circ_0062270 interacted with RNA-binding protein (RBP) EIF4A3. Furthermore, in vivo study indicated that knockdown of hsa_circ_0062270 inhibited the melanoma tumor growth in vivo. CONCLUSIONS: Downregulation of hsa_circ_0062270 can inhibit the progression of melanoma through downregulation of CDC45. Our findings provide biological mechanisms for the use of hsa_circ_0062270 as a biomarker for melanoma and potential therapeutic target.

Cerebrospinal Fluid Leak Detection with a Carbon Nanotube-Based Field-Effect Transistor Biosensing Platform

xlomafota13 shared this article with you from Inoreader Cerebrospinal Fluid Leak Detection with a Carbon Nanotube-Based Field-Effect Transistor Biosensing Platform Via leak of cerebrospinal fluid ACS Appl Mater Interfaces. 2021 Dec 21. doi: 10.1021/acsami.1c19120. Online ahead of print. ABSTRACT Cerebrospinal fluid (CSF) leakage may lead to life-threatening complications if not detected promptly. However, gel electrophoresis, the gold-standard test for confirming CSF leakage by detecting beta2-transferrin (β2-Tf), requires 3-6 h and is labor-intensive. We developed a new β2-Tf detection platform for rapid identification of CSF leakage. The three-step design, which includes two steps of affinity chromatography and a rapid sensing step using a semiconductor-enriched single-walled carbon nanotube field-effect transistor (FET) sensor, circumvented the lack of selectivity that antitransferrin antibody exhibits for transferrin isoforms and markedly shortened the detection time. Furthermore, three different sensing configurations for the FET sensor were investigated for obtaining the optimal β2-Tf sensing results. Finally, body fluid (CSF and serum) tests employing our three-step strategy demonstrated high sensitivity, suggesting its potential to be used as a rapid diagnostic tool for CSF leakage.

Stereotactic radiotherapy as planned boost after definitive radiotherapy for head and neck cancers: Systematic review

xlomafota13 shared this article with you from Inoreader Stereotactic radiotherapy as planned boost after definitive radiotherapy for head and neck cancers: Systematic review Via Head & Neck Abstract Management of locoregionally advanced head and neck cancers (HNCs) remains a challenge. Some groups have attempted to use stereotactic radiotherapy (SBRT) to deliver "boost" treatment following conventional radiotherapy to improve local control (LC) and overall survival (OS), while aiming for acceptable toxicities. Medline, EMBASE, and Cochrane Library databases were queried for SBRT as curative-intent planned boost in HNC after conventional radiotherapy. Individual studies were reviewed from inception until January 2021, extracting patient, treatment, and outcome data. Nine studies met inclusion criteria, representing 454 unique patients treated with curative intent across multiple head and neck sites with conventional radiotherapy. At 3 years, median LC was 92% (90%–98%), and median OS was 80% (75%–91%). Seven treatment-related grade 5 toxicities (1.5%) were reported. Despite acceptable LC and OS rates, there were severe treatment-related late toxicities. As such, SBRT boost should only be used in investigational settings until more data is available.

Oligometastatic adenoid cystic carcinoma: Correlating tumor burden and time to treatment with outcomes

xlomafota13 shared this article with you from Inoreader Oligometastatic adenoid cystic carcinoma: Correlating tumor burden and time to treatment with outcomes Via Head & Neck Abstract Background There is limited information on the management and outcomes of oligometastases (OM) in adenoid cystic carcinoma (ACC). Methods Retrospective study of 42 patients with metastatic ACC of the head and neck. Imaging studies were analyzed to identify patients with OM (1–5 lesions) at any point during follow-up. Results There was radiographic evidence of OM in 33/42 (79%) patients. Eighteen patients had OM when treated for metastases, with median overall survival (OS) of 36.0 versus 9.2 years for patients with polymetastases (6+ lesions, HR 0.38, 95%CI 0.14–0.89). Earlier locally ablative treatment, but not systemic treatment, of patients with OM predicted improved survival 3 years after metastasis (HR 0.15, 95%CI 0.02–0.63) and postponed systemic treatment by 80 more months (HR 0.22, 95%CI 0.07–0.71). Conclusions There is a considerable population of ACC patients with detectable oligometastases, and early locally ablative treatment of oligometastases may be associated with improved outcomes.

A multi-centred sequential trial comparing PEGASUS, an intervention to promote shared decision making about breast reconstruction with usual care

xlomafota13 shared this article with you from Inoreader A multi-centred sequential trial comparing PEGASUS, an intervention to promote shared decision making about breast reconstruction with usual care Via Journal of plastic, reconstructive & aesthetic surgery : JPRAS J Plast Reconstr Aesthet Surg. 2021 Nov 15:S1748-6815(21)00577-5. doi: 10.1016/j.bjps.2021.11.033. Online ahead of print. ABSTRACT Decision making about breast reconstruction (BR) is complex. The Patients' Expectations and Goals: Assisting Shared Understanding of Surgery (PEGASUS) intervention aims to support shared decision making by helping women and clinicians clarify and discuss their expectations around reconstructive surgery. We conducted a multi-centred sequential trial comparing PEGASUS (n = 52) with usual care (UC) (n = 86) in women considering reconstruction, who completed outcome measures at baseline, and 3, 6 and 12 months post-surgery. The primary outcome was BR-specific quality of life (Breast-Q) 6 months post-intervention. Secondary outcomes were health-related quality of life (EQ-5D-5L), capabilities (ICECAP-A) and decisional regret, compared using t-tests and Cohen's d. Comparative analyses revealed no significant diff erences between groups in Breast-Q scores at any time point, except for a favourable effect for UC on psychological well-being at 3 months (t = -2.41, p = .019, d= -0.59). Intervention participants reported significantly higher, therefore improved, ICECAP-A (t = -2.13, p = .037, d = -0.45) and EQ VAS (t = -2.28, p = .026, d = -0.49) scores at 12 months compared to UC. Decisional regret was significantly lower in the PEGASUS group compared to the UC group at 6 months (t =2.06, p = .044, d= -0.51), but this was not sustained at 12 months. In conclusion, the PEGASUS intervention offers some benefits to women considering BR. At times, women experienced less decisional regret, improved health-related quality of life and capability well-being. Findings are discussed in the light of fidelity testing and embedding PEGASUS into practice. PMID:34924325 | DOI:10.1016/j.bjps.2021.11.033 View on the web Inoreader.

Assessment of deep inferior epigastric perforator flap perfusion with near-infrared fluorescence: A pilot study and description of a standardized working protocol

xlomafota13 shared this article with you from Inoreader Assessment of deep inferior epigastric perforator flap perfusion with near-infrared fluorescence: A pilot study and description of a standardized working protocol Via Journal of plastic, reconstructive & aesthetic surgery : JPRAS J Plast Reconstr Aesthet Surg. 2021 Nov 16:S1748-6815(21)00590-8. doi: 10.1016/j.bjps.2021.11.043. Online ahead of print. ABSTRACT Fat necrosis (FN) is a common complication after autologous breast reconstruction (ABR) using a free flap, which can influence reconstruction outcome and patient satisfaction. Intraoperative near-infrared fluorescence imaging using indocyanine green (ICG) permits the visualization of flap perfusion. The aim of this study was to assess the effect of near-infrared fluorescence on FN incidence in patients undergoing an ABR with a deep inferior epigastric perforator flap (DIEP) and to propose a standard working protocol for this technique. In this prospective study, patients undergoing one-sided ABR with a DIEP were included. The standard DIEP procedure was complemented with near-infrared fluorescence imaging using the fluorescent tracer ICG to evaluate flap perfusion. This cohort was compared to a retrospectiv e cohort of DIEP procedures without near-infrared fluorescence imaging. Patients and surgery characteristics, as well as postoperative complications, were registered and compared. In both cohorts, 24 patients were included. No significant differences were present between patients and surgery characteristics, including no difference in duration of surgery. In the prospective and retrospective group, the incidence of FN was 4.2% and 33%, respectively (p-value = 0.023). Moreover, microsurgeons were positive about using near-infrared fluorescence as it either provided additional information about perfusion or confirmed the clinical assessment. Our pilot study showed a significant decrease of FN in patients undergoing an ABR with a DIEP when near-infrared fluorescence imaging was used to assess flap perfusion. This study provides a standardized working protocol for near-infrared fluorescence imaging. In the future, large multicenter studies should focus on the quantification of near-infr ared fluorescence imaging. PMID:34924327 | DOI:10.1016/j.bjps.2021.11.043 View on the web Inoreader.
