Prompt diagnosis of this leukoencephalopathy is essential, since preliminary data suggest that it could represent a potentially treatable disorder.In light of recent advances in HIV prevention and treatment, we reviewed the literature to understand how different types of stigma impact HIV risk; access to HIV prevention, care, and treatment services; and related health outcomes among men who have sex with men (MSM) in the US. We conducted a scoping literature review of observational and qualitative studies that examined stigma and HIV-related outcomes among MSM. Our search identified 5794 studies, of which 47 met the eligibility criteria and were included in the final analysis. The review suggests that stigma remains a formidable barrier to engaging in HIV prevention and treatment among both HIV-negative and HIV-positive MSM. Among the studies of HIV-positive MSM, internalized stigma was related to lower levels of treatment engagement. HIV-positive MSM in the Southern part of the US were also more likely to engage in risky sexual behavior. Perceived health care discrimination was negatively associated with PrEP awareness, particularly among HIV-negative Black MSM. Among young MSM of color, intersectional stigma compounded the social structural barriers to PrEP adherence. Findings indicate that stigma reduction interventions should be implemented in diverse MSM communities to address the disproportionate burden of HIV along with critical gap in the care continuum. Further research should examine how individual types of stigma, including intersectional stigma, affect viral suppression and PrEP uptake and adherence, especially among MSM of color.
  The goal of this study was to determine whether the benefits of multiphase CTA (mCTA) over single-phase CTA (sCTA) for the detection of proximal cerebrovascular occlusions similarly extend to the distal cerebral vasculature.
 
  Four attending radiologists, two neuroradiologists and two emergency radiologists, contributed as readers to this retrospective study. For each reader, two sessions were conducted, one using sCTA and one using mCTA. During each session, the reader interpreted the studies of 104 patients who underwent imaging for suspicion of acute ischemic stroke, resulting in a total of 832 interpretations. Changes in diagnostic accuracy, time to render final decision, and reported levels of reader confidence were quantitatively assessed. Further analysis comparing the effects for neuroradiologists versus emergency radiologists was additionally conducted.
 
  Using mCTA resulted in a significant 5.0% absolute increase in sensitivity (91.6% vs. 96.6%, p = .004) and an insignificant increase in specificity (99.5% vs. 99.7%, p = .39). A significant reduction in reading time (66.7s vs. 59.6s, p = .001) and an increase in diagnostic confidence (2.26 vs. 2.58, p < .001) were observed. Using sCTA, higher sensitivity was achieved by neuroradiologists than emergency radiologists (96.0% vs. 86.9%, p = .002); using mCTA resulted in an absolute increase in sensitivity of 0.9% (97.4%, p = .44) for neuroradiologists and 9.6% (96.5%, p < .001) for emergency radiologists, eliminating significant differences between the groups (p = 0.57).
 
  The use of mCTA results in increased sensitivity and negative predictive value, decreased reading time, increased diagnostic confidence, and the elimination of differences in accuracy between neuroradiologists and emergency radiologists.

  Prostate cancer is the second leading cause of cancer death in men, and cardiovascular disease is the number one cause of death in patients with prostate cancer. Androgen deprivation therapy, the cornerstone of prostate cancer treatment, has been associated with adverse cardiovascular events. Emerging data supports decreased cardiovascular risk of gonadotropin releasing hormone (GnRH) antagonists compared to agonists. Ongoing clinical trials are assessing the relative safety of different modalities of androgen deprivation therapy. Racial disparities in cardiovascular outcomes in prostate cancer patients are starting to be explored. An intriguing inquiry connects androgen deprivation therapy with reduced risk of COVID-19 infection susceptibility and severity. Recognition of the cardiotoxicity of androgen deprivation therapy and aggressive risk factor modification are crucial for optimal patient care.

  Importation of taxadiene synthase into chloroplasts is important for the efficient heterologous production of taxadiene. Taxadiene, the first committed precursor to taxol, is synthesized from geranylgeranyl pyrophosphate (GGPP) by action of taxadiene synthase (TS). Heterologous production of taxadiene could potentially rely on both cytosolic mevalonic acid (MVA) pathway and the plastidic methylerythritol phosphate (MEP) pathway. We suggest the compartmentalized engineering in chloroplast as an efficient approach for taxadiene production. In this study, we directly introduced the TS gene from Taxus brevifolia into the tobacco chloroplast genome and found that the transplastomic plants accumulated a low content of taxadiene, ~ 5.6μg/g dry weight (DW). Moreover, we tried a combination of MEP and MVA pathways for taxadiene synthesis by nuclear transformation with a truncated version of TS (without encoding a transit peptide) into the transplastomic plants. However, this did not further improve the taxadiene production.
