clinicaltrials.gov NCT04363411, Registered 27 April 2020-Retrospectively registered. https//clinicaltrials.gov/ct2/show/NCT04363411?term=NCT04363411&draw=2&rank=1.The outbreak of the novel coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has emerged as a serious public health concern. Patients with cancer have been disproportionately affected by this pandemic. Increasing evidence has documented that patients with malignancies are highly susceptible to severe infections and mortality from COVID-19. Recent studies have also elucidated the molecular relationship between the two diseases, which may not only help optimize cancer care during the pandemic but also expand the treatment for COVID-19. In this review, we highlight the clinical and molecular similarities between cancer and COVID-19 and summarize the four major signaling pathways at the intersection of COVID-19 and cancer, namely, cytokine, type I interferon (IFN-I), androgen receptor (AR), and immune checkpoint signaling. In addition, we discuss the advantages and disadvantages of repurposing anticancer treatment for the treatment of COVID-19.The clinical outcome of patients with a diagnosis of hormone receptor (HR)+ breast cancer has improved remarkably since the arrival of endocrine therapy. Yet, resistance to standard treatments is a major clinical challenge for breast cancer specialists and a life-threatening condition for the patients. In breast cancer, mismatch repair (MMR) status assessment has been demonstrated to be clinically relevant not only in terms of screening for inherited conditions such as Lynch syndrome, but also for prognostication, selection for immunotherapy, and early identification of therapy resistance. Peculiar traits characterize the MMR biology in HR+ breast cancers compared to other cancer types. In these tumors, MMR genetic alterations are relatively rare, occurring in ~3 % of cases. On the other hand, modifications at the protein level can be observed also in the absence of gene alterations and vice versa. In HR+ breast cancers, the prognostic role of MMR deficiency has been confirmed by several studies, but its predictive value remains a matter of controversy. The characterization of MMR status in these patients is troubled by the lack of tumor-specific guidelines and/or companion diagnostic tests. For this reason, precise identification of MMR-deficient breast cancers can be problematic. A deeper understanding of the MMR biology and clinical actionability in HR+ breast cancer may light the path to effective tumor-specific diagnostic tools. For a precise MMR status profiling, the specific strengths and limitations of the available technologies should be taken into consideration. This article aims at providing a comprehensive overview of the current state of knowledge of MMR alterations in HR+ breast cancer. The available armamentarium for MMR testing in these tumors is also examined along with possible strategies for a tailored pathological characterization.

While leading AIDS organizations expect faith and health collaborations to play a crucial role in organizing and scaling up community-based HIV services, it is unclear how this can be realized. Little primary research has been conducted into which strategies for collaboration and service provision are most effective, efficient, scalable and sustainable. Seeking to align research with urgent needs, enhance coordination and increase the likelihood that results are used, this study aimed to set an inclusive global research agenda that reflects priority research questions from key stakeholders at the intersection of HIV healthcare and faith.

In order to develop this global research agenda, we drew from document analyses, focus group discussions, interviews with purposively selected key informants from all continents (policy-makers, healthcare providers, faith leaders, academics and HIV activists), an online questionnaire, and expert meetings at several global conferences. We carried out focus group discussionhemes improving the engagement of faith communities in addressing sexuality and tackling stigma.

A wide range of respondents participated in developing the research agenda. To align research to the prioritized themes and ensure that results are used, it is essential to further engage key users, funders, researchers and other stakeholders, strengthen the capacity for locally embedded research and research uptake and contextualize priorities to diverse religious traditions, key populations and local circumstances.

In response to the "know-do" gap, several initiatives have been implemented to enhance evidence-informed decision-making (EIDM). These include individual training, organizational culture change management, and legislative changes. The importance of relationships and stakeholder engagement in EIDM has led to an evolution of models and approaches including integrated knowledge translation (IKT). IKT has emerged as a key strategy for ensuring that engagement is equitable, demand-driven, and responsive. EGFR inhibitors cancer As a result, the African-German Collaboration for Evidence-Based Healthcare and Public Health in Africa (CEBHA+) incorporated an IKT approach to influence noncommunicable diseases (NCD) policy and practice. We documented the phased process of developing, implementing, and monitoring the IKT approach in South Africa; and explored the appropriateness of using the exploration, preparation, implementation, and sustainment (EPIS) framework for this purpose.

We mapped the South Africa IKT approach onto the EPIS framuseful. Phase-agnostic constructs proved critical to ensure resilience and agility of NCD deliberations and policies in the face of highly dynamic and changing local contexts, particularly in view of the current coronavirus disease 2019 (COVID-19) pandemic. Bridging IKT with a framework from implementation science helps to reflect on this process and can guide the development and planning of similar interventions and strategies.

Using the EPIS framework to interrogate, reflect on, and document our IKT experiences proved extremely relevant and useful. Phase-agnostic constructs proved critical to ensure resilience and agility of NCD deliberations and policies in the face of highly dynamic and changing local contexts, particularly in view of the current coronavirus disease 2019 (COVID-19) pandemic. Bridging IKT with a framework from implementation science helps to reflect on this process and can guide the development and planning of similar interventions and strategies.

Pregnant women and developing fetuses comprise a particularly vulnerable population as multiple studies have shown associations between prenatal air pollution exposure and adverse pregnancy outcomes. However, the mechanisms underlying the observed developmental toxicity are mostly unknown, in particular, if pollution particles can cross the human placenta to reach the fetal circulation.

Here, we investigated the accumulation and translocation of diesel exhaust particles (DEPs), as a model particle for combustion-derived pollution, in human perfused placentae using label-free detection by femtosecond pulsed laser illumination. The results do not reveal a significant particle transfer across term placentae within 6 h of perfusion. However, DEPs accumulate in placental tissue, especially in the syncytiotrophoblast layer that mediates a wealth of essential functions to support and maintain a successful pregnancy. Furthermore, DEPs are found in placental macrophages and fetal endothelial cells, showing that some particles can overcome the syncytiotrophoblasts to reach the fetal capillaries. Few particles are also observed inside fetal microvessels.

Overall, we show that DEPs accumulate in key cell types of the placental tissue and can cross the human placenta, although in limited amounts. These findings are crucial for risk assessment and protection of pregnant women and highlight the urgent need for further research on the direct and indirect placenta-mediated developmental toxicity of ambient particulates.

Alcohol use is a common practice of almost all communities worldwide and it is more common among persons with HIV infection. Alcohol consumption among people with HIV/AIDS may result in poor treatment adherence, further immunity suppression and increase the risk of comorbid illness (diseases) which collectively diminish the anti-retroviral therapy responses. Although there are separate studies conducted regarding alcohol use among people with HIV/AIDS in Ethiopia, the finding results are highly variable and inconsistent. Therefore, conducting a systematic review and meta-analysis has a paramount importance to show the pooled prevalence of alcohol use and to identify its determinants among people with HIV/AIDS.

A systematic search of electronic databases of PubMed/Medline, Science Direct, Hinnari and Cochrane library was employed. Additionally, the grey literature was searched from Google and Google Scholar. Data were extracted using a standardized data extraction format prepared in Microsoft Excel . STATAcohol use. Comorbid substance use (khat and cigarette) increases the risk of alcohol consumption among HIV patients. This suggests a need for designing appropriate and culturally applicable intervention programs and policy responses. Trial registration PROSPERO 2019, "CRD42019132524."

The result of this review showed that alcohol drinking is highly practiced among people with HIV/AIDS in Ethiopia. The magnitude of alcohol use was highly variable based on the screening methods used to measure alcohol use. Comorbid substance use (khat and cigarette) increases the risk of alcohol consumption among HIV patients. This suggests a need for designing appropriate and culturally applicable intervention programs and policy responses. Trial registration PROSPERO 2019, "CRD42019132524."

Gastric cancer (GC) is general disease in human digestive system with malignancy. Emerging findings indicated that hsa_circ_0031452 (circHECTD1) was strictly associated with carcinogenesis. Nevertheless, the role of circHECTD1 in drug-resistance still needed to be explained.

Quantitative real-time polymerase chain reaction (qRT-PCR) was employed to examine the expression profiles of circHECTD1, microRNA (miR)-137, and pre-leukemia transcription factor 3 (PBX3). The function of circHECTD1 in tumorigenesis was evaluated via xenograft tumor model. The IC

of Diosbulbin-B (DB) was detected using Cell Counting Kit-8 (CCK8). Cell-cycle and apoptosis were reckoned by flow cytometry. Besides, western blot was administrated to reckon the levels of PBX3 and cell apoptotic indicators. Moreover, the interrelation between miR-137 and circHECTD1 or PBX3 was expounded by dual-luciferase reporter, RNA immunoprecipitation (RIP) and RNA pull down assays.

We uncovered that circHECTD1 was ectopically up-regulated in GC tissues and cells.
