A simple abiological host-guest system demonstrates racemase activity with catalytic rate enhancements of 104 without employing traditional functional groups. Cooperative weak interactions enhanced through shape-complementarity between the catalyst active site and the reaction transition state drive this activity, as proposed by Pauling for enzymes. In analogy to the Jencks' concept of catalytic antibodies, it is shown that a hapten resembling the planar transition state of the bowl inversion acts as a potent inhibitor of this catalytic process. In contrast, no substrate/product inhibition is detected, and a relatively weak binding of the substrate is observed (Ka ≈ 102 M-1 at 293 K). This simple box-and-bowl system demonstrates that shape selectivity arising from cooperative dispersive forces suffices for the emergence of a catalytic system with an enzyme-like thermodynamic profile.
This study aimed to investigate the prevalence of hospital readmission for chronic obstructive pulmonary disease (COPD) at 30, 90 and 365 days, and to determine demographic and socioeconomic risk factors for 30-day and 90-day readmission and time to COPD-related readmission within 365 days in Tasmania.
Patients ≥40 years admitted for COPD between 2011 and 2015 were identified using administrative data from all major public hospitals in Tasmania, Australia. Factors associated with readmission and time to readmission were identified using logistic and Cox regression, respectively.
The rates of COPD-related readmission were 6.7% within 30 days, 12.2% within 90 days and 23.7% within 365 days. Being male (odds ratio [OR] 1.49, CI 1.06-2.09), Indigenous (OR 2.47, CI 1.31-4.66) and living in the lower socioeconomic North-West region of Tasmania (OR 1.80, CI 1.20-2.69) were risk factors for 30-day readmission. Increased COPD-related (OR 1.48, CI 1.22-1.80; OR 1.52, CI 1.29-1.78) and non-COPD-related (OR 1.12, CI 1.03- 1.23; OR 1.11, CI 1.03-1.21) emergency department (ED) visits in the preceding six months were risk factors for both 30-day and 90-day readmissions. Being Indigenous (hazard ratio [HR] 1.61, CI 1.10-2.37) and previous COPD-related ED visits (HR 1.30, CI 1.21-1.39) decreased, while a higher Charlson Comorbidity Index (CCI) (OR 0.91, CI 0.83- 0.99) increased the time to readmission within 365 days.
Being male, Indigenous, living in the North-West region and previous ED visits were associated with increased risk of COPD readmission in Tasmania. Interventions to improve access to primary healthcare for these groups may reduce COPD-related readmissions.

Philanthropic activities play an important role in health systems. Donors contribute to financing, generating resources, and providing healthcare services in Iranian health system. However, they face many challenges. This study aimed to identify barriers to donors' participation in the Iranian health system and to provide solutions.
This qualitative study was performed using semi-structured interviews with 38 donors and 26 policy-makers and managers in the social affairs department of health ministry and medical universities in 2018. In addition, document analysis was performed and the relevant data were extracted. Thematic analysis was used for data analysis. All ethical considerations were followed in this research.
Insufficient structures, poor communications, low trust, ineffective working processes, bureaucracy, insufficient senior managers' support, weak legal support and poor monitoring were the most important challenges for donors' participation in the Iranian health system. Effective donor parters and managers should tackle these challenges and adopt strategies to reinforce donors' participation in the health system. Planning, organizing, leading, monitoring, evaluation, transparency, accountability, and a commitment to meet donors' needs are necessary for successful philanthropy initiatives in the health sector.Addressing conflicts of interest (COIs) when developing and implementing policies to address commercial determinants of health is pivotal to ensure that these policies are free from commercial and other vested interests of unhealthy commodities industry. As a concept, this is well accepted within the tobacco control community, and supported by the existence of an international treaty, the WHO Framework Convention on Tobacco Control (FCTC). But in nutrition policy the engagement of the food industry appears to remain controversial, as efforts to create partnerships are still underway. There is a need to undertake evaluation of existing COI policies to assess their implementation and outcomes, creating best practice models that can be replicated, and understanding how to change norms within governments. Additionally, a review of existing norms, codes of conduct, and ethics to determine their impact on preventing COI would guide future implementation of these measures. Finally, governments, academics, and advocates should consider how existing tools, guidelines or other instruments could help frame the COI discussion to ensure its political feasibility. There is a need for a discussion on whether the current approach of separate policies for distinct industries is preferable than a broader COI policy that would be applicable to a wide range of unhealthy commodities and across governmental sectors.
The effects of climate change, soil depletion, a growing world population putting pressure on food safety and security are major challenges for agriculture in the 21st century. selleck chemicals The breeding success of the green revolution has decelerated and current programs can only offset the yield affecting factors.
New approaches are urgently needed and "Genome Editing-accelerated Re-Domestication" (GEaReD) is proposed as a major new direction in plant breeding. By combining the upcoming technologies for phenotyping, omics, and artificial intelligence with the promising new CRISPR-toolkits, this approach is closer than ever.
Wild relatives of current crops are often adapted to harsh environments and have a high genetic diversity. Redomestication of wild barley or teosinte could generate new cultivars adapted to environmental changes. De novo domestication of perennial relatives such as Hordeum bulbosum could counter soil depletion and increase soil carbon. Recent research already proved the principle of redomestication in tomato and rice and therefore laid the foundation for GEaReD.

Recent research already proved the principle of redomestication in tomato and rice and therefore laid the foundation for GEaReD.Sensor-integrated wound dressings are emerging tools applicable to a wide variety of medical applications from emergency triage to at-home monitoring. Uncomfortable, unnecessary wound dressing changes may be avoided by providing quantitative insight into tissue characteristics related to wound healing such as tissue oxygenation, pH, and exudate/transudate volume. Here, a simple cost-effective methodology for quantifying oxygen and pH in a swellable hydrogel dressing using a single photograph is presented. The red and green luminescence of a novel dendritic polyamine Pt-porphyrin and fluorescein conjugate quantitatively responds to oxygen and pH, respectively, and enables robust sensing. The porphyrin conjugate, when combined with a four-arm star polyethylene glycol (PEG) amine polymer, rapidly crosslinks at room temperature with an N-hydroxysuccinimide (NHS)-PEG crosslinker to form a color-changing hydrogel dressing with tunable swelling capabilities applicable to a variety of wound environments. An inexpensive digital single-lens reflex (DSLR) camera modified with bandpass filters captures the hydrogel luminescence using simple macroscopic photography, and conversion to HSB colorspace allows for intensity-independent image analysis of the hydrogels' dual modality response. The hydrogel formulation exhibits a robust and validated visible red-orange-green "traffic light" spectrum in response to oxygen changes, regardless of swelling state, pH, or autofluorescence from skin, thereby enabling the clinician friendly naked-eye feedback.Obstructive sleep apnea (OSA) is associated with treatment-resistant hypertension and high cardiovascular risk. Continuous positive airway pressure (CPAP) fails to reduce cardiovascular risks consistently. Obesity and OSA show reciprocal association and they synergistically increase hypertension via different pathways. Our meta-analysis aimed to assess the cardiovascular benefits of combining weight loss (WL) with CPAP (vs. WL or CPAP alone) in OSA. Outcomes included systolic and diastolic blood pressure (BP) and blood lipid parameters. We explored Medline, Embase, Cochrane, and Scopus. Eight randomized controlled studies (2627 patients) were included. The combined therapy decreased systolic BP more than CPAP alone. Weighted mean difference (WMD) for CPAP + WL versus CPAP was -8.89 mmHg, 95% confidence interval (95% CI; -13.67 to -4.10, p less then 0.001) for systolic BP. For diastolic BP, this decrease was not significant. In case of blood lipids, the combined treatment decreased triglyceride levels more than CPAP alone (WMD = -0.31, 95% CI -0.58 to -0.04, p = 0.027). On the other hand, addition of CPAP to WL failed to suppress BP further. The certainty of evidence according to GRADE was very low to moderate. In conclusion, our results showed that the addition of WL to CPAP significantly improved BP and blood lipid values in OSA. On the other hand, the addition of CPAP to WL could not significantly improve BP or blood lipid values. Review protocol PROSPERO CRD42019138998.
Indocyanine green (ICG) lymphography can be performed to obtain realtime fluorescent images of the thoracic duct (TD). The injection of ICG into the inguinal nodes usually is ultrasound-guided. Our hypothesis was to simplify the ICG administration until making it executable by unqualified personnel without ultrasound guidance.
From October 2019 to October 2021 we enroled 18 patients. ICG was injected with a 25 Gauge needle in the subcutaneous tissue of the inguinal region bilaterally 14-16h before surgery.
The TD was visualised in every case considered. The easy switching between fluorescence and white light visualization facilitated the identification and dissection of the TD avoiding involuntary injuries.
The simplified ICG administration to identify TD during oesophagectomy is easy to perform, does not require specifically trained staff, is not time demanding and has comparable results to the procedure performed under ultrasound guide.
