Antimicrobial Use, Residues, Resistance and Governance in the Food and Agriculture Sectors, Tanzania.

Antibiotics (Basel) 2021 Apr 16;10(4). Epub 2021 Apr 16.

Emergency Centre for Transboundary Animal Diseases (ECTAD), Food and Agriculture Organization of the United Nations (FAO), Dar es Salaam 14111, Tanzania.

All infections are potentially curable as long as the etiological agents are susceptible to antimicrobials. The increased rate at which antimicrobials are becoming ineffective is a global health risk of increasing concern that threatens withdrawal of beneficial antimicrobials for disease control. The increased demand for food of animal origin, in particular eggs, meat and milk has led to intensification and commercial production systems where excessive use and misuse of antimicrobials may prevail.

Health Misinformation about Toxic-Site Harm: The Case for Independent-Party Testing to Confirm Safety.

Int J Environ Res Public Health 2021 Apr 7;18(8). Epub 2021 Apr 7.

Department of Economics, University of Notre Dame, 3060 Jenkins Nanovic Hall, Notre Dame, IN 46556, USA.

Health misinformation can cause harm if regulators or private remediators falsely claim that a hazardous facility is safe. This misinformation especially threatens the health of children, minorities, and poor people, disproportionate numbers of whom live near toxic facilities. Yet, perhaps because of financial incentives, private remediators may use safety misinformation to justify reduced cleanup. Read More

Improving Patient Flow and Decreasing Patient Length of Stay in the Pediatric Emergency Department Through Implementation of a Fast Track.

Adv Emerg Nurs J 2021 Apr-Jun 01;43(2):162-169

Department of Emergency Medic-ine (Dr Martin), Pediatric Emergency Nursing (Ms Noble), and Emergency Nursing (Ms Wilmarth), Univer-sity of Rochester Medical Center, Rochester, New York.

Increased utilization of the emergency department (ED) for low acuity concerns saturates EDs, leading to overcrowding. As the ED becomes crowded, the quality of care threatens patient safety and increases length of stay. To improve the efficiency of evaluation and discharge of low acuity patients in the pediatric ED, a performance improvement project was implemented to develop a Fast Track. Read More

Peroxiredoxin alleviates the fitness costs of imidacloprid resistance in an insect pest of rice.

PLoS Biol 2021 Apr 12;19(4):e3001190. Epub 2021 Apr 12.

State Key Laboratory of Biocontrol, School of Life Sciences, Sun Yat-sen University, Guangzhou, Guangdong, China.

Chemical insecticides have been heavily employed as the most effective measure for control of agricultural and medical pests, but evolution of resistance by pests threatens the sustainability of this approach. Resistance-conferring mutations sometimes impose fitness costs, which may drive subsequent evolution of compensatory modifier mutations alleviating the costs of resistance. However, how modifier mutations evolve and function to overcome the fitness cost of resistance still remains unknown. Read More

Drug repurposing for next-generation combination therapies against multidrug-resistant bacteria.

Theranostics 2021 4;11(10):4910-4928. Epub 2021 Mar 4.

College of Veterinary Medicine, Yangzhou University, Yangzhou, Jiangsu, China.

Antimicrobial resistance has been a global health challenge that threatens our ability to control and treat life-threatening bacterial infections. Despite ongoing efforts to identify new drugs or alternatives to antibiotics, no new classes of antibiotic or their alternatives have been clinically approved in the last three decades. A combination of antibiotics and non-antibiotic compounds that could inhibit bacterial resistance determinants or enhance antibiotic activity offers a sustainable and effective strategy to confront multidrug-resistant bacteria.

Procedural Competency Among Hospitalists: A Literature Review and Future Considerations.

J Hosp Med 2021 Apr;16(4):230-235

Department of Medicine, Beth Israel Deaconess Medical Center, Boston, Massachusetts; Harvard Medical School, Boston, Massachusetts.

Background: As general internists practicing in the inpatient setting, hospitalists at many institutions are expected to perform invasive bedside procedures, as defined by professional standards. In reality, hospitalists are doing fewer procedures and increasingly are referring to specialists, which threatens their ability to maintain procedural skills. The discrepancy between expectations and reality, especially when hospitalists may be fully credentialed to perform procedures, poses significant risks to patients because of morbidity and mortality associated with complications, some of which derive from practitioner inexperience.

Kern Center for the Science of Health Care Delivery, Mayo Clinic, Rochester, MN; Division of Health Care Policy and Research, Mayo Clinic, Rochester, MN; Department of Medicine, and Division of Community Pediatric and Adolescent Medicine and Division of Pediatric Infectious Diseases, Department of Pediatric and Adolescent Medicine, Mayo Clinic, Rochester, MN. Electronic address:

The success of vaccination programs is contingent upon irrefutable scientific safety data combined with high rates of public acceptance and population coverage. Vaccine hesitancy, characterized by lack of confidence in vaccination and/or complacency about vaccination that may lead to delay or refusal of vaccination despite the availability of services, threatens to undermine the success of coronavirus disease 2019 (COVID-19) vaccination programs. The rapid pace of vaccine development, misinformation in popular and social media, the polarized sociopolitical environment, and the inherent complexities of large-scale vaccination efforts may undermine vaccination confidence and increase complacency about COVID-19 vaccination.

Sulfamoylbenzamide-based Capsid Assembly Modulators for Selective Inhibition of Hepatitis B Viral Replication.

ACS Med Chem Lett 2021 Feb 2;12(2):242-248. Epub 2021 Feb 2.

Therapeutics & Biotechnology Division, Korea Research Institute of Chemical Technology, Daejeon 34114, Republic of Korea.

As the spread of infections caused by hepatitis B virus (HBV) threatens public health worldwide, investigations from multiple perspectives and of various mechanisms of action are urgently required to increase the HBV cure rate. Targeting the encapsidation of the nuclear capsid protein (core protein, HBc) has emerged as an attractive strategy for inhibiting the viral assembly process; however, a drug targeting this mechanism has not yet been approved. We synthesized novel sulfamoylbenzamides (SBAs) as capsid assembly modulators of HBV and found that the effects and safety profiles of compounds and have potential therapeutic applicability against HBV.
