A novel iodide-catalyzed intermolecular aminooxygenation strategy is described here. Amide is used as the O- and N- source to probe for regiocontrol strategies. Notably, simple additives can be selectively introduced to achieve regiodivergent oxyamination processes for electronically activated alkenes while being regio-complementary for unactivated alkenes. Our preliminary data demonstrates that this regiocontrol strategy based on nucleophile can also be applied in asymmetric processes using chiral hypervalent iodine catalysis.To compare the management and outcomes of colorectal cancer (CRC) patients during the first 2 months of the COVID-19 pandemic with the preceding 6 months. The pandemic has affected the diagnosis and treatment of CRC patients worldwide. Little is known about the safety of major resection and whether creating "cold" sites (COVID-free hospitals) is effective. A national study in England used administrative hospital data for 14,930 CRC patients undergoing surgery between October 1, 2019, and May 31, 2020. Mortality of CRC resection was compared before and after March 23, 2020 ("lockdown" start). The number of elective CRC procedures dropped sharply during the pandemic (from average 386 to 214 per week), whereas emergency procedures were hardly affected (from 88 to 84 per week). https://www.selleckchem.com/products/17-AAG(Geldanamycin).html There was little change in characteristics of surgical patients during the pandemic. Laparoscopic surgery decreased from 62.5% to 35.9% for elective and from 17.7% to 9.7% for emergency resections. Surgical mortality increased slightly (from 0.9% to 1.2%, = 0.06) after elective and markedly (from 5.6% to 8.9%, = 0.003) after emergency resections. The observed increase in mortality during the first phase of the pandemic was similar in "cold" and "hot" sites ( > 0.5 elective and emergency procedures). The pandemic resulted in a 50% reduction in elective CRC procedures during the initial surge and a substantial increase in mortality after emergency resection. There was no evidence that surgery in COVID-free "cold" sites led to better outcomes in the first 2 months.

A number of psychological assessment tools have been developed to describe various dimensions of gender. Some of these tools are restricted to a binary gender concept and are inflexible in reflecting how a young person's gender may change and develop over time. Most are text questionnaires which require a good level of literacy. This study aimed to evaluate a newly developed pictorial tool that facilitates a conversation about gender between a child or adolescent (aged 11-18) and their clinician, enabling a diverse understanding and expression of gender identity. The Perth Gender Picture (PGP) was co-created between clinicians and young clients between 2016 and 2018. In 2018, the measure was evaluated through a pilot study at the Gender Diversity Service at Perth Children's Hospital in Western Australia. After use of the PGP during a clinical consultation, clients were invited to fill in a feedback questionnaire about their experience of its use. Clinicians participated in unstructured interviews to givpotential for use in other age groups and non-clinical contexts.Background Testicular prostheses implantation may be used for neoscrotal augmentation in transgender men. In current literature, explantation rates range from 0.6% to 30% and most are a result of infection or extrusion. Information on the surgical path of individuals after prosthesis explantation is scarce. Aim To assess the frequency and success rate of testicular prosthesis implantation after previous explantation due to infection or extrusion. Methods All transgender men who underwent testicular prosthesis explantation between January 1991 and December 2018 were retrospectively identified from a departmental database. A retrospective chart study was conducted, recording demographics, surgical and prosthesis characteristics, reoperations, and outcomes. Results A total of 41 transgender men were included who underwent testicular prosthesis explantation in the study time period. Of these, 28 (68%) opted for new prosthesis implantation. Most explanted prosthesis had a volume ≥30cc and were replaced with an equally sized one. The postoperative course was uneventful in 19 out of 28 (68%) individuals. Explantation of one or both prostheses occurred in 7 out of 28 (25%) individuals, because of infection (n = 3, 11%) or extrusion (n = 4, 14%). Patients that experienced complications had more often a history of smoking (p = 0.049). The explantation rate was lower if a smaller or lighter prosthesis was reimplanted (p = 0.020). Discussion Most patients opt for testicular prosthesis implantation after previous explantation due to extrusion or infection. Explantation rates are higher than after the primary implantation procedure. Results of current study can be used to inform individuals on postoperative outcomes.Background Transgender and gender expansive (TGE) youth face a number of adversities that are associated with deleterious consequences, including mental health problems, substance misuse, suicide, and homelessness. However, there is evidence that TGE youth still demonstrate resilience under extraordinary conditions. Aims Therefore, this study examined how TGE youth who are homeless and engaging in survival sex describe and understand the protective factors present in their lives. Methods In-depth qualitative interviews were conducted with 57 TGE youth living in a large U.S. city. Participants were 17-26 years old (M = 19.88, SD = 1.55), and identified as transgender woman (53%), transgender man (16%), and other (32%; gender-queer, gender-fluid, androgynous, or non-binary). Youth identified as Black (40%), multiracial (35%), Latinx (16%), White (5%), and as another race (3%). Researchers conducted a secondary analysis of qualitative data using thematic analysis. Results We identified three themes to capture youth's understanding of their protective factors relying on oneself and others to avoid violence, accessing gender-affirming health and mental health care, and proactively maintaining sexual health.
