CXCR4-guided liposomes regulating hypoxic and immunosuppressive microenvironment for sorafenib-resistant tumor treatment
Authors: Yuehua Wang, Zhenjie Wang, Fei Jia, Qing Xu, Zhilin Shu, Junlin Deng, Aimin Li, Meng Yu, Zhiqiang Yu
Journal: Bioactive Materials (2022)

Clinical sorafenib treatment could activate C-X-C receptor type 4 (CXCR4)/stromal source factor-1α (SDF-1α) axis to aggravate intra-tumoral hypoxia of hepatocellular carcinoma (HCC), which further leads to progression, invasion, metastasis, and immunosuppression of tumors and in return causes resistance to sorafenib therapy. Therefore, a multi-functional oxygen delivery nanoplatform was rationally constructed based on an oxygen-saturated perfluorohexane (PFH)-cored liposome, with the CXCR4 antagonist LFC131 peptides modifying on the surface to simultaneously deliver sorafenib and the CSF1/CSF1R inhibitor PLX3397 (named PFH@LSLP) for sorafenib-resistant HCC treatment. The PFH@LSLP was developed to overcome sorafenib resistance by synergistic effects of the following 3 roles: 1) the O2-saturated PFH core could alleviate the tumor hypoxia by O2 supply; 2) the LFC131 peptide recognized the hypoxia-related overexpressed CXCR4 and then blocked SDF-1α/CXCR4 axis to re-sensitize the HCC cells to sorafenib; 3) PLX3397 activated the immune responses via inhibiting the CSF1/CSF1R pathway in TAMs, further enhanced CD8+ T cell infiltration to reverse immunosuppression in tumors. Antitumor performance on H22 tumor-bearing mice and HCC patient-derived tumor xenograft (PDX) model showed that PFH@LSLP could overcome sorafenib resistance by synergistic effect of hypoxia attenuation, resistance-related gene regulation, and immune-microenvironment modification.
Cults
Authors: John G. Clark
Journal: JAMA (1979)

THE PRACTICES of a rapidly expanding number of groups or cults, most calling themselves religions, are of great interest and concern to physicians, for frequently they must face either direct family involvement or a clinical problem of real urgency as a result of cult activities. To respond with professional competence is most difficult without some prior knowledge of the nature of these organizations and the problems generated by their activities. <h3>Members</h3> The new youth cults, though usually self-styled as religious for purposes of first amendment privileges, are increasingly dangerous to the health of their converts and menacing to their critics. Estimates of total US membership extend anywhere from 3 to 10 million people involved in more than 3,000 groups ranging in size from two or three members obeying a guru to many thousands. Their prominence is best demonstrated by the fact that almost everyone now knows some family who has

FTY720, a novel immunosuppressant, prolonged the survival of WKAH skin allografts transplanted into MHC-incompatible F344 rats. In this allograft model, the median survival time of the control group was 7 days, whereas those of the groups given FTY720 orally at 0.1 mg/kg and cyclosporin A (CsA) at 10 mg/kg were 10.5 and 11 days, respectively. In contrast, FTY720 (0.1 mg/kg) combined with CsA (10 mg/kg) synergistically prolonged allograft survival with a median survival time exceeding 70 days. To elucidate the mechanisms of this remarkable synergistic effect, mRNA expressions of IL-2 and IFN-γ and that of CD3 (δ-chain), which reflects T cell infiltration, in allografts were temporally analyzed using a semiquantitative PCR method. In WKAH skin allografts, mRNA levels of IL-2, IFN-γ, and CD3 were increased as compared with isograft controls, peaking on days 4 to 5. CsA (10 mg/kg) significantly inhibited elevations of IL-2 and IFN-γ mRNA, while slightly inhibiting that of CD3 mRNA in allografts. On the contrary, FTY720 (0.1 mg/kg) markedly inhibited the elevation of CD3 mRNA, while slightly inhibiting those of IL-2 and IFN-γ mRNA. FTY720 (0.1 mg/kg) combined with CsA (10 mg/kg) almost completely suppressed the intragraft expressions of mRNA for IL-2, IFN-γ, and CD3. Immunohistochemical staining and flow cytometric analysis also confirmed that FTY720 decreased T cell infiltration into allografts. From these results, the synergistic effect of FTY720 combined with CsA on prolongation of allograft survival is presumably based on the respective inhibitions of T cell infiltration and cytokine production in grafts.
A phase Ib/II, multicenter, open-label study of AK104, a PD-1/CTLA-4 bispecific antibody, combined with chemotherapy (chemo) as first-line therapy for advanced gastric (G) or gastroesophageal junction (GEJ) cancer.

308 Background: Anti-PD-1 agent plus chemo as first-line therapy for advanced G/GEJ cancer (Checkmate-649) yields OS and PFS benefits compared to chemo alone, indicating synergistic activity between immune checkpoint inhibitors and chemo. The combination of anti-PD-1 and anti-CTLA-4 has consistently demonstrated higher response rate compared to PD-1 monotherapy but higher toxicity. Here, we performed this phase Ib/II study to evaluate the efficacy and safety of AK104, a PD-1/CTLA-4 bispecific antibody, combined with XELOX (capecitabine combined with oxaliplatin) or modified XELOX (mXELOX) in the first-setting of G/GEJ cancer cohorts. This study is registered on ClinicalTrials.gov (NCT03852251). Methods: Pts with unresectable advanced G/GEJ adenocarcinoma and no prior systemic therapy, regardless of PD-L1 status were enrolled, excluding known HER2-positive pts. Enrolled patients received AK104 (4 mg/kg, 6 mg/kg, 10 mg/kg, Q2W or 10 mg/kg, 15mg/kg Q3W) + chemo (mXELOX Q2W or XELOX Q3W). The primary endpoint was objective response rate (ORR) based on Response Evaluation Criteria in Solid Tumors version 1.1 (RECIST v1.1). Results: As of 13 Aug 2021, 96 pts were enrolled with median age 62.7 years (range: 29–75), 70.8% male, 62.5% ECOG PS 1, 44.8% liver metastasis. The median follow-up was 9.95 months (range, 0.4-26.8). 88 patients (92%) had at least one post-baseline tumor evaluation. The ORR was 65.9% (58/88) with 2 (2.3%) complete responses and 56 (63.6%) partial responses. The disease control rate (DCR) was 92.0% (81/88). The median duration of response (DoR) was 6.93 months (95%CI, 4.60 to 11.20). The median PFS was 7.10 months (95%CI, 5.55 to 10.48). The median OS was 17.41 months (95%CI, 12.35 to NE). In pts with PD-L1 CPS≥1 vs CPS＜1, median OS was 17.41 months and 14.65 months, respectively. Treatment-related adverse events (TRAEs) occurred in 97.9% of pts, and the most frequent were platelet count decreased (60.4%), white blood cell count decreased (58.3%), neutrophil count decreased (56.3%), anaemia (47.9%), nausea (30.2%), vomiting (30.2%), aspartate aminotransferase increased (30.2%). Grade ≥3 TRAEs occurred in 62.5% pts. No new safety signals were identified. Conclusions: AK104 in combination with mXELOX/XELOX showed promising activity and manageable safety in previously untreated pts with advanced G/GEJ adenocarcinoma. AK104 + chemo represents a potential new first-line treatment option for these pts. A phase III study of AK104 combined with chemo as first-line therapy for G/GEJ cancer is underway. Clinical trial information: NCT03852251.

Journal: JAMA Network Open (2022)

<h3>Importance</h3> Misinformation about COVID-19 vaccination may contribute substantially to vaccine hesitancy and resistance. <h3>Objective</h3> To determine if depressive symptoms are associated with greater likelihood of believing vaccine-related misinformation. <h3>Design, Setting, and Participants</h3> This survey study analyzed responses from 2 waves of a 50-state nonprobability internet survey conducted between May and July 2021, in which depressive symptoms were measured using the Patient Health Questionnaire 9-item (PHQ-9). Survey respondents were aged 18 and older. Population-reweighted multiple logistic regression was used to examine the association between moderate or greater depressive symptoms and endorsement of at least 1 item of vaccine misinformation, adjusted for sociodemographic features. The association between depressive symptoms in May and June, and new support for misinformation in the following wave was also examined. <h3>Exposures</h3> Depressive symptoms. <h3>Main Outcomes and Measures</h3> The main outcome was endorsing any of 4 common vaccine-related statements of misinformation. <h3>Results</h3> Among 15 464 survey respondents (9834 [63.6%] women and 5630 [36.4%] men; 722 Asian respondents [4.7%], 1494 Black respondents [9.7%], 1015 Hispanic respondents [6.6%], and 11 863 White respondents [76.7%]; mean [SD] age, 47.9 [17.5] years), 4164 respondents (26.9%) identified moderate or greater depressive symptoms on the PHQ-9, and 2964 respondents (19.2%) endorsed at least 1 vaccine-related statement of misinformation. Presence of depression was associated with increased likelihood of endorsing misinformation (crude odds ratio [OR], 2.33; 95% CI, 2.09-2.61; adjusted OR, 2.15; 95% CI, 1.91-2.43). Respondents endorsing at least 1 misinformation item were significantly less likely to be vaccinated (crude OR, 0.40; 95% CI, 0.36-0.45; adjusted OR, 0.45; 95% CI, 0.40-0.51) and more likely to report vaccine resistance (crude OR, 2.54; 95% CI, 2.21-2.91; adjusted OR, 2.68; 95% CI, 2.89-3.13). Among 2809 respondents who answered a subsequent survey in July, presence of depression in the first survey was associated with greater likelihood of endorsing more misinformation compared with the prior survey (crude OR, 1.98; 95% CI, 1.42-2.75; adjusted OR, 1.63; 95% CI, 1.14-2.33). <h3>Conclusions and Relevance</h3> This survey study found that individuals with moderate or greater depressive symptoms were more likely to endorse vaccine-related misinformation, cross-sectionally and at a subsequent survey wave. While this study design cannot address causation, the association between depression and spread and impact of misinformation merits further investigation.

COVID-19 coagulopathy: an evolving story
Authors: None The Lancet Haematology
Journal: The Lancet Haematology (2020)

As the coronavirus disease 2019 (COVID-19) exceeds 4 million cases worldwide, spreading across all continents as of May 12, 2020, we can assert both the substantial mortality in at-risk groups and the multiple manifestations of this disease. It is now clear that among hospitalised patients with COVID-19, pneumonia, sepsis, and respiratory failure are frequent complications, with some patients developing severe systemic disease and multiorgan failure. Moreover, since the initial report from Wuhan in January 2020 suggested elevated D-dimers and prolonged prothrombin time were baseline characteristics of patients critically ill with COVID-19, the burden of thrombotic complications in these patients has been confirmed.

Diagnosis and Treatment of Sexually Transmitted Infections
Authors: Susan Tuddenham, Matthew M. Hamill, Khalil G. Ghanem
Journal: JAMA (2022)

<h3>Importance</h3> Approximately 1 in 5 adults in the US had a sexually transmitted infection (STI) in 2018. This review provides an update on the epidemiology, diagnosis, and treatment of gonorrhea, chlamydia, syphilis,<i>Mycoplasma genitalium</i>, trichomoniasis, and genital herpes. <h3>Observations</h3> From 2015 to 2019, the rates of gonorrhea, chlamydia, and syphilis increased in the US; from 1999 to 2016, while the rates of herpes simplex virus type 1 (HSV-1) and HSV-2 declined. Populations with higher rates of STIs include people younger than 25 years, sexual and gender minorities such as men and transgender women who have sex with men, and racial and ethnic minorities such as Black and Latinx people. Approximately 70% of infections with HSV and trichomoniasis and 53% to 100% of extragenital gonorrhea and chlamydia infections are asymptomatic or associated with few symptoms. STIs are associated with HIV acquisition and transmission and are the leading cause of tubal factor infertility in women. Nucleic acid amplification tests have high sensitivities (86.1%-100%) and specificities (97.1%-100%) for the diagnosis of gonorrhea, chlamydia,<i>M genitalium</i>, trichomoniasis, and symptomatic HSV-1 and HSV-2. Serology remains the recommended method to diagnose syphilis, typically using sequential testing to detect treponemal and nontreponemal (antiphospholipid) antibodies. Ceftriaxone, doxycycline, penicillin, moxifloxacin, and the nitroimidazoles, such as metronidazole, are effective treatments for gonorrhea, chlamydia, syphilis,<i>M genitalium,</i>and trichomoniasis, respectively, but antimicrobial resistance limits oral treatment options for gonorrhea and<i>M genitalium</i>. No cure is available for genital herpes. Effective STI prevention interventions include screening, contact tracing of sexual partners, and promoting effective barrier contraception. <h3>Conclusions and Relevance</h3> Approximately 1 in 5 adults in the US had an STI in 2018. Rates of gonorrhea, chlamydia, and syphilis in the US have increased, while rates of HSV-1 and HSV-2 have declined. Ceftriaxone, doxycycline, penicillin, moxifloxacin, and the nitroimidazoles are effective treatments for gonorrhea, chlamydia, syphilis,<i>Mycoplasma genitalium</i>, and trichomoniasis, respectively, but antimicrobial resistance limits oral therapies for gonorrhea and<i>Mycoplasma genitalium</i>, and no cure is available for genital herpes.

Journal: Pharmacological Reviews (2022)

The number of successful drug development projects has been stagnant for decades despite major breakthroughs in chemistry, molecular biology, and genetics. Unreliable target identification and poor translatability of preclinical models have been identified as major causes of failure. To improve predictions of clinical efficacy and safety, interest has shifted to three-dimensional culture methods in which human cells can retain many physiologically and functionally relevant phenotypes for extended periods of time. Here, we review the state of the art of available organotypic culture techniques and critically review emerging models of human tissues with key importance for pharmacokinetics, pharmacodynamics, and toxicity. In addition, developments in bioprinting and microfluidic multiorgan cultures to emulate systemic drug disposition are summarized. We close by highlighting important trends regarding the fabrication of organotypic culture platforms and the choice of platform material to limit drug absorption and polymer leaching while supporting the phenotypic maintenance of cultured cells and allowing for scalable device fabrication. We conclude that organotypic and microphysiological human tissue models constitute promising systems to promote drug discovery and development by facilitating drug target identification and improving the preclinical evaluation of drug toxicity and pharmacokinetics. There is, however, a critical need for further validation, benchmarking, and consolidation efforts ideally conducted in intersectoral multicenter settings to accelerate acceptance of these novel models as reliable tools for translational pharmacology and toxicology. <h3>Significance Statement</h3> Organotypic and microphysiological culture of human cells has emerged as a promising tool for preclinical drug discovery and development that might be able to narrow the translation gap. This review discusses recent technological and methodological advancements and the use of these systems for hit discovery and the evaluation of toxicity, clearance, and absorption of lead compounds.
