RESUMO
This paper reviews progress in tobacco litigation since Tobacco Control's founding 30 years ago, with a focus on cases which are ongoing or recently decided. Litigation in tobacco control falls into several classes: legal challenges brought by the tobacco industry to block implementation of tobacco control measures, public interest litigation brought by civil society to push for higher standards of implementation of tobacco control measures and liability litigation by governments and individuals to hold the tobacco industry accountable for the harm it causes. In each class of cases, there are a number of major case studies which show the importance of international frameworks, including most significantly the WHO Framework Convention on Tobacco Control, to tobacco litigation.

BACKGROUND: Since the WHO Framework Convention on Tobacco Control's (FCTC) entry into force, the tobacco industry has initiated litigation challenging tobacco control measures implemented by governments around the world, or supported others to initiate such litigation on its behalf. In defending their tobacco control measures against such litigation, governments have invoked their obligations and rights under the WHO FCTC. We assess the extent to which the WHO FCTC has provided legal weight to governments' defences against legal challenge. METHODS: We reviewed 96 court decisions concerning legal challenges to tobacco control measures, determining whether or not they cited the WHO FCTC and their outcomes. We then reviewed the cases where the WHO FCTC was cited, analysing how the WHO FCTC contributed to the resolution of the case. RESULTS: The WHO FCTC was cited in 45 decisions. Decisions both citing and not citing the WHO FCTC were largely decided in favour of governments, with 80% of WHO-FCTC-citing and 67% of non-WHO-FCTC-citing cases upholding the measure in its entirety and on every ground of challenge. In cases where it was cited, the WHO FCTC contributed to the resolution of the case in favour of governments by providing a legal basis for measures, demonstrating the measure's public health purpose, demonstrating the evidence in favour of a measure, demonstrating international consensus, demonstrating that a measure promotes or protects health-related human rights and demonstrating whether or not a measure is reasonable, proportionate or justifiable. CONCLUSIONS: The way the WHO FCTC has been cited in court decisions suggests that it has made a substantial contribution to courts' reasoning in tobacco control legal challenges and has strengthened governments' arguments in defending litigation.

BACKGROUND: Nerve interposition grafting is an important technique in nerve reconstructive surgery that is used when a primary repair is not feasible without significant tension. This study sought to evaluate the long-term morbidity of the medial antebrachial cutaneous (MABC) nerve as an alternative donor nerve in comparison with sural nerve harvest. METHODS: A single surgeon and institution retrospective chart review was performed to identify all patients who underwent nerve autografting using the sural and MABC as donor nerves between January 1, 2000 and December 31, 2019. Surveys assessed overall patient satisfaction with surgery, as well as donor and recipient site morbidity, satisfaction, pain, numbness, and cold sensitivity. RESULTS: Of the 73 patients contacted, 54 agreed to participate, and 43 of 73 (58.9%) ultimately completed the survey: 28 MABC (65.1%) and 15 sural (34.9%). There were no significant differences between the sural and MABC groups in overall satisfaction with surgery, donor and recipient site satisfaction, pain, cold sensitivity, and effect on quality of life. Even though 66.7% of sural donor sites and 75% of MABC donor sites had residual numbness, the effect this had on quality of life was very low (2 and 3, respectively). CONCLUSION: The MABC is a safe alternative to the traditional sural nerve autograft. A small subset of patients undergoing nerve autograft harvest will experience long-term morbidity in the form of pain. Conversely, the more common presence of numbness is not reported as bothersome.
RESUMO
Objective: To evaluate the role of disease-modifying antirheumatic drugs (DMARDs) on wound healing outcomes of patients with autoimmune disease at our tertiary wound care center. Approach: Retrospective review of patients presenting to our wound care center between 2014 and 2018 with both chronic wounds and a history of inflammatory disease. Patient demographics, comorbid conditions, and progression to complete wound healing were compared between those taking DMARDs or not at the time of wound onset. The study adheres to the STROBE statement. Results: Fifty-eight patients with a total of 296 wounds were retrospectively reviewed. Patients were taking at least one DMARD at wound onset in 217 (73.3%) of these wounds. The average number of DMARDs at wound onset was 1.5 (standard deviation 1.2). Two hundred ten wounds progressed to heal (70.9%), with a median time to healing of 229.5 days (interquartile range 71.0-490.0). Of the 210 wounds that healed, patients taking at least one DMARD had a significantly shorter time to healing relative to patients who were not on any DMARDs (median 190.5 days vs. 340.0 days, p = 0.0156). Innovation: Characterizing wound healing outcomes at a tertiary hospital with a dedicated wound care center and analyzing the role of DMARDs in wound healing progression. Conclusions: The median time to healing in the studied cohort was 229.5 days, which is much longer than the healing time for noninfected diabetic foot ulcers at our institution. These findings highlight the wound healing challenges posed by underlying autoimmune disease.10.

Computational chemical biology, applied to research on hepatitis B virus (HBV), has two major branches: bioinformatics (statistical models) and first-principle methods (molecular physics). While bioinformatics focuses on statistical tools and biological databases, molecular physics uses mathematics and chemical theory to study the interactions of biomolecules. Three computational techniques most commonly used in HBV research are homology modeling, molecular docking, and molecular dynamics. Homology modeling is a computational simulation to predict protein structure and has been used to construct conformers of the viral polymerase (reverse transcriptase domain and RNase H domain) and the HBV X protein. Molecular docking is used to predict the most likely orientation of a ligand when it is bound to a protein, as well as determining an energy score of the docked conformation. Molecular dynamics is a simulation that analyzes biomolecule motions and determines conformation and stability patterns. All of these modeling techniques have aided in the understanding of resistance mutations on HBV non-nucleos(t)ide reverse-transcriptase inhibitor binding. Finally, bioinformatics can be used to study the DNA and RNA protein sequences of viruses to both analyze drug resistance and to genotype the viral genomes. Overall, with these techniques, and others, computational chemical biology is becoming more and more necessary in hepatitis B research. This article forms part of a symposium in Antiviral Research on "An unfinished story: from the discovery of the Australia antigen to the development of new curative therapies for hepatitis B."
