Although complication rates after thyroidectomy are well described in the literature, the timing of these events is less understood. This study delineates the timeline and risk factors for early adverse events after thyroidectomy.

This study included a retrospective review of 161,534 patients who underwent thyroidectomy between 2005 and 2018 using the American College of Surgeons National Surgical Quality Improvement Program database. check details Time to specific complications was analyzed for all patients undergoing thyroidectomy, with further stratification of hemithyroidectomy and total thyroidectomy cohorts. Univariate analyses were conducted to analyze demographics, preoperative comorbidities, and complications. A multivariate logistic regression model was generated to identify significant risk factors for 7-day postoperative complications.

The overall complication rate was 3.28%. A majority of complications arose before discharge including the following blood transfusion (96%), hematoma formation (68%), pneumstablish better preoperative communication and education to improve postoperative expectations for the provider and patient.

Although early complications after thyroidectomy are rare, they have a distinct time course, many of which occur after discharge. However, in selected patients undergoing outpatient thyroidectomy, overall risk of complications is decreased. Understanding timing helps establish better preoperative communication and education to improve postoperative expectations for the provider and patient.

Female surgeons are highly underrepresented in Asian countries, where prescriptive gender norms are widespread and more deeply embedded in societies.

A nationwide structured questionnaire was completed by 1741 Singaporean third- and fifth-year medical students after the completion of an 8-week general surgery rotation, during 2015-2017. Results were analyzed using mixed-effects hierarchical models which took into account clustering of survey responses under the teaching hospitals which students were posted to and medical students' year of study.

Female medical students had a poorer perception of general surgery than male students (3.22±0.91 versus 3.41±0.89; P<0.0001) before the clerkship. However, the clerkship improved female students' opinion to a greater extent than male students (+0.84±1.06 versus +0.59±1.03; P<0.0001), resulting in female and male students having comparable attitudes toward surgery after the clerkship (4.06±0.79 versus 4.00±0.87; P=0.2435). A total of 40.4% of female studenttudents to surgery.

A surgical clerkship itself could be regarded as an effective intervention for improving female medical students' enthusiasm for surgery, which may help to address the "pipeline problem" of few female students applying for surgical training after medical school. A greater emphasis on "pull factors" and pedagogical qualities of mentors could be used to improve the clerkship experience, to attract more female students to surgery.Hydrogels based on photocrosslinkable Hyaluronic Acid Methacrylate (HAMA) and Chondroitin Sulfate Methacrylate (CSMA) are presently under investigation for tissue engineering applications. HAMA and CSMA gels offer tunable characteristics such as tailorable mechanical properties, swelling characteristics, and enzymatic degradability. This review gives an overview of the scientific literature published regarding the pre-clinical development of covalently crosslinked hydrogels that (partially) are based on HAMA and/or CSMA. Throughout the review, recommendations for the next steps in clinical translation of hydrogels based on HAMA or CSMA are made and potential pitfalls are defined. Specifically, a myriad of different synthetic routes to obtain polymerizable hyaluronic acid and chondroitin sulfate derivatives are described. The effects of important parameters such as degree of (meth)acrylation and molecular weight of the synthesized polymers on the formed hydrogels are discussed and useful analytical techniques for their characterization are summarized. Furthermore, the characteristics of the formed hydrogels including their enzymatic degradability are discussed. Finally, a summary of several recent applications of these hydrogels in applied fields such as cartilage and cardiac regeneration and advanced tissue modelling is presented.Microbes have remarkable capabilities to attach to the surface of implanted medical devices and form biofilms that adversely impact device function and increase the risk of multidrug-resistant infections. The physicochemical properties of biomaterials have long been known to play an important role in biofilm formation. More recently, a series of discoveries in the natural world have stimulated great interest in the use of 3D surface topography to engineer antifouling materials that resist bacterial colonization. There is also increasing evidence that some medical device surface topographies, such as those designed for tissue integration, may unintentionally promote microbial attachment. Despite a number of reviews on surface topography and biofilm control, there is a missing link between how bacteria sense and respond to 3D surface topographies and the rational design of antifouling materials. Motivated by this gap, we present a review of how bacteria interact with surface topographies, and what can be learned from current laboratory studies of microbial adhesion and biofilm formation on specific topographic features and medical devices. We also address specific biocompatibility considerations and discuss how to improve the assessment of the anti-biofilm performance of topographic surfaces. We conclude that 3D surface topography, whether intended or unintended, is an important consideration in the rational design of safe medical devices. Future research on next-generation smart antifouling materials could benefit from a greater focus on translation to real-world applications.Chemo-resistance is an important barrier to effective treatment of ovarian cancer. Poly (ADP-ribose) polymerase (PARP) inhibitors are currently promising targeted drugs used to treat BRCA-mutant ovarian cancer. Ovarian cancer patients with BRCA 1/2 mutations appear to benefit better from PARP inhibitors and chemotherapy. Understanding the mechanisms underlying PARP inhibitors and chemotherapy resistance is urgently needed. There is increasing evidence that microRNAs (miRNAs) are involved in drug resistance. MiR-506-3p is an effective inhibitor of the epithelial-to-mesenchymal transition (EMT), and can enhance chemotherapy and olaparib response in high-grade serous ovarian cancer (HGS-OvCa). Enhancer of Zeste Homolog 2 (EZH2) is considered as a direct target of miR-506-3p. The silencing of EZH2 mimics the inhibitory effects of miR-506-3p on chemo-resistance and olaparib response. Rescue of EZH2 prevented the functions of miR-506-3p. Moreover, EZH2 activates the β-catenin pathway. MiR-506-3p overexpression decreased the level of β-catenin, and the sensitivity to olaparib and cisplatin mediated by miR-506-3p was partially reversed by regulating β-catenin expression in ovarian cancer.
