Overall results demonstrate that 3 months of Tat exposure increased morphine tolerance and potentially innate immune tolerance evidenced by reductions in specific cytokines (e.g., IL-1α, IL-12p40) and microglial reactivity. In contrast, short-term, escalating morphine exposure acted as a secondary stressor revealing an allostatic shift in CNS baseline inflammatory responsiveness from sustained Tat exposure.

Clinical Ethics Committees (CECs) are well established at healthcare institutions in resource-rich countries. However, there is limited information on established CECs in resource poor countries, especially in Africa. This study aimed to establish baseline data regarding existing formal CECs in Africa to raise awareness of and to encourage the establishment of CECs or Clinical Ethics Consultation Services (CESs) on the continent.

A descriptive study was undertaken using an online questionnaire via SunSurveys to survey healthcare professionals and bioethicists in Africa. Data were subjected to descriptive analysis and Fischer's exact test was applied to determine associations. AGI-24512 Texts from the open-ended questions were thematically analysed.

In total 109 participants from 37 African countries completed the survey in December 2019. A significant association was found between participants' bioethics qualification or training and involvement in clinical ethics (p = 0.005). All participants were familiar with d their role in improving the quality of health care in Africa is sorely needed.

Recent increases in health professions education (HPE) research in sub-Saharan Africa (SSA), though substantial, have predominantly originated from single institutions and remained uncoordinated. A shared research agenda can guide the implementation of HPE practices to ultimately influence the recruitment and retention of the health workforce. Thus, the authors aimed to generate and prioritise a list of research topics for HPE research (HPER) in SSA.

A modified Delphi process was designed to prioritise a shared agenda. Members of the African Forum for Research and Education in Health (AFREhealth) technical working group (TWG) were asked to first list potential research topics. Then, members of the same TWG and attendees at the annual AFREhealth academic symposium held in Lagos, Nigeria in August 2019 rated the importance of including each topic on a 3-point Likert scale, through two rounds of consensus seeking. Consensus for inclusion was predefined as ≥70% of respondents rating the topic as "must be inclarch priorities for HPE is important to ensure efficient and appropriate allocation of resources. This study serves as a reminder of how the prevailing context within which HPE, and by implication research in the field, is undertaken will inevitably influence choices about research foci. It further points to a potential advocacy role for research that generates regionally relevant evidence.

A common challenge for free-access systems is that people may bypass primary care and seek secondary care through self-referral. Taiwan's government has undertaken various initiatives to mitigate bypass; however, little is known about whether the bypass trend has decreased over time. This study examined the extent to which patients bypass primary care for treatment of common diseases and factors associated with bypass under Taiwan's free-access system.

This repeated cross-sectional study analyzed data from Taiwan's National Health Insurance Research Database. A random sample of 1 million enrollees was drawn repeatedly from the insured population during 2000-2017. To capture visits beyond the community level, the bypass rate was defined as the proportion of self-referred visits to the top two levels of providers, namely academic medical centers and regional hospitals, among all visits to all providers. Subgroup analyses were conducted for visits with a single diagnosis. Logistic regressions were used to inkelihood of bypass. These results may help policymakers to develop strategies to mitigate bypass.

Systematic cancer screening has led to the increased detection of pre-malignant lesions (PMLs). The absence of reliable prognostic markers has led mostly to over treatment resulting in potentially unnecessary stress, or insufficient treatment and avoidable progression. Importantly, most mutational profiling studies have relied on PML synchronous to invasive cancer, or performed in patients without outcome information, hence limiting their utility for biomarker discovery. The limitations in comprehensive mutational profiling of PMLs are in large part due to the significant technical and methodological challenges most PML specimens are small, fixed in formalin and paraffin embedded (FFPE) and lack matching normal DNA.

Using test DNA from a highly degraded FFPE specimen, multiple targeted sequencing approaches were evaluated, varying DNA input amount (3-200ng), library preparation strategy (BE Blunt-End, SS Single-Strand, AT A-Tailing) and target size (whole exome vs. cancer gene panel). Variants in high-inpR1 gains, TP53 loss) and measure intra-lesion genetic heterogeneity.

Alternate experimental and analytical strategies increased the accuracy of DNA sequencing from archived micro-dissected PML regions, supporting the deeper molecular characterization of early cancer lesions and achieving a critical milestone in the development of biology-informed prognostic markers and precision chemo-prevention strategies.
