The strategies for the development of novel antibacterial agents include natural product isolation as well as synthetic and semi-synthetic methodologies. This review presents an overview of the periodontal diseases gingivitis and periodontitis along with current antibacterial treatment options (i.e., classes of antibacterial agents and the mechanism(s) of resistance that hinder their usage) used in periodontal diseases that specifically target oral pathogens such as P. gingivalis. In addition, to help medicinal chemists gain a better understanding of potentially promising scaffolds, this review provides an in-depth coverage of the various families of small molecules that have been investigated as potential anti-P. gingivalis agents, including novel families of compounds, repositioned drugs, as well as natural products.The reconnection of the scientific community with phenotypic drug discovery has created exciting new possibilities to develop therapies for diseases with highly complex biology. It promises to revolutionise fields such as neurodegenerative disease and regenerative medicine, where the development of new drugs has consistently proved elusive. Arguably, the greatest challenge in readopting the phenotypic drug discovery approach exists in establishing a crucial chain of translatability between phenotype and benefit to patients in the clinic. This remains a key stumbling block for the field which needs to be overcome in order to fully realise the potential of phenotypic drug discovery. Excellent quality chemical probes and chemistry-based target deconvolution techniques will be a crucial part of this process. In this review, we discuss the current capabilities of chemical probes and chemistry-based target deconvolution methods and evaluate the next advances necessary in order to fully support phenotypic screening approaches in drug discovery.Deprived communities in many cities are exposed to higher levels of outdoor air pollution, and there is increasing evidence of similar disparities for indoor air pollution exposure. There is a need to understand the drivers for this exposure disparity in order to develop effective interventions aimed at improving population health and reducing health inequities. With a focus on London, UK, this paper assembles evidence to examine why indoor exposure to PM2.5, NOx and CO may disproportionately impact low-income groups. In particular, five factors are explored, namely housing location and ambient outdoor levels of pollution; housing characteristics, including ventilation properties and internal sources of pollution; occupant behaviours; time spent indoors; and underlying health conditions. Evidence is drawn from various sources, including building physics models, modelled outdoor air pollution levels, time-activity surveys, housing stock surveys, geographical data, and peer-reviewed research. selleck chemicals A systems frameworA systems approach is used to show how these factors lead to systemic exposure inequalities, with low-income households having limited opportunities to improve their indoor air quality. This paper can inform actions and public policies to reduce environmental health inequalities, considering both indoor and outdoor air.

The COVID-19 pandemic has led to death and hardship around the world, and increased popular discourse about end-of-life circumstances and conditions. The extent to which this discourse and related pandemic experiences have precipitated advance care planning (ACP) activities was the focus of this study with a particular emphasis on sexual orientation.

A large, national online survey was conducted between 10 August and 10 October 2020 in Canada. The final sample of 3923 persons aged 55 and older was recruited using social media, direct email, and Facebook advertising and in conjunction with community groups. Women comprised almost 78% of the sample; just more than 7% of the sample identified as lesbian, gay, and bisexual (LGB). Measures included demographic variables and a series of questions on ACP, including documents and discussions undertaken prior to the pandemic and since its onset.

Descriptive analyses revealed few gender or sexual orientation differences on documents and discussions prior to the pandemic; since its onset, LGB persons have completed or initiated wills, powers of attorney, advance directives, representation agreements, and have engaged in ACP discussions in greater proportion than heterosexuals. Logistic regressions reveal the increased likelihood of pre-pandemic ACP engagement by age, gender (women), and education; since the pandemic onset, gender, education, and sexual orientation were predictive of greater ACP engagement. Care discussions were more likely undertaken by women and LGB persons since the pandemic most often with spouses, family, and friends, especially among LGB persons.

Gender roles and previous pandemic experiences (HIV/AIDS, in particular) are implicated in this pattern of results; opportunities for educational interventions are considered.

Approximately one-third of patients with colorectal cancer develop liver metastases during the natural course of disease. Complete surgical resection is associated with very low mortality in colorectal liver metastasis patients, but only a small fraction of colorectal liver metastasis patients fulfill the selection criteria for surgical treatment. We herein describe a high-risk stage-IV rectal carcinoma patient who was initially unresectable according to the National Comprehensive Cancer Network guidelines with a clinical risk score of 4 but received conversion surgery combined with systemic chemotherapy and achieved a favorable long-term clinical outcome (pathologic complete response) of approximately 28 months. Furthermore, serial circulating tumor DNA monitoring using next-generation sequencing provided a comprehensive view of the patient's clinical and pathologic status for better clinical decision support over the course of the disease.
