Kick-Fukui: A new Fukui Function-Guided Way for Molecular Composition Prediction.
To evaluate the effect of perioperative meloxicam IV 30 mg on opioid consumption in primary total knee arthroplasty (TKA).

Multicenter, randomized, double-blind, placebo-controlled trial.

181 adults undergoing elective primary TKA.

Subjects received meloxicam 30 mg or placebo via an IV bolus every 24 hours, the first dose administered prior to surgery as part of a multimodal pain management protocol. The primary efficacy parameter was total opioid use from end of surgery through 24 hours.

Meloxicam IV was associated with less opioid use versus placebo during the 24 hours after surgery (18.9 ± 1.32 vs 27.7 ± 1.37 mg IV morphine equivalent dose; P < 0.001) and was superior to placebo on secondary endpoints, including summed pain intensity (first dose to 24 hrs postdosing, first dose to first assisted ambulation, and first dose to discharge) and opioid use (48-72 hrs., 0-48 hrs., 0-72 hrs., hour 0 to end of treatment, and the first 24 hours after discharge). Adverse events (AEs) were reported for 69.9% and 92.0% of the meloxicam IV and placebo groups, respectively; the most common AEs were nausea (40% vs. 59%), vomiting (16% vs. 22%), hypotension (14% vs. 15%), pruritus (15% vs. 11%), and constipation (11% vs. 13%).

Perioperative meloxicam IV 30 mg as part of a multimodal analgesic regimen for elective primary TKA reduced opioid consumption in the 24-hour period after surgery versus placebo and was associated with a lower incidence of AEs typically associated with opioid use.

Participants were tested with four different RDT types. PCR testing was performed as the reference standard. Sensitivity and specificity were broadly similar across RDT types and sampling method. Agreement between sample type was high, ranging from 0.95 to 0.99. When following the manufacturer's recommended interpretation, only five tests would have resulted in a different clinical diagnosis. These results demonstrate that malaria RDTs perform similarly when using capillary or venous blood in febrile children with P. falciparum malaria.
To date, published data regarding long-lasting immunological rabies memory after a pre-exposure prophylaxis (PrEP)-schedule are scarce. We tested the hypothesis that rabies booster immunization elicits rapid anamnestic responses.

For this observational study, we included participants who had received PrEP 10-24 years before inclusion. We measured rabies antibody titers before, and on days 3, 7 and 14 after one single intramuscular booster.

All 28 participants responded adequately regardless route of administration or (2-dose vs. 3-dose) PrEP-regimen.

Rabies immunological memory is reactivated within 7 days after a single intramuscular booster immunization, even when administered 10-24 years after PrEP.

Since January 2002, pre-deployment training of forward resuscitative and surgical units has taken place at the U.S. Army Trauma Training Center (ATTC) in Miami, FL. In June 2019, the 240th Forward Resuscitative Surgical Team (FRST) conducted the first pre-deployment Surgical Readiness Training Exercise (SURGRETE) in San Pedro Sula, Honduras, to allow the team to rehearse in a resource-constrained environment more similar to that expected on deployment. The purpose of this study is to describe and compare the pre-deployment training experiences of the 240th FRST during their SURGRETE in Honduras and ATTC rotation in Miami, FL.

A descriptive analysis of prospectively collected data was performed for surgical cases, trauma resuscitations, and nonsurgical procedures by the 240th FRST over a 2-week SURGRETE in Honduras and 2-week ATTC rotation in Miami, FL. Items accomplished within the Individual Critical Task Lists (ICTLs) of key clinical providers on the team (general surgeon, orthopedic surgeon, emergency cross-training. The SURGRETE experience could be improved by locating a facility with a trauma-dominant patient population that allows increased autonomy of U.S. physicians.
Appropriately planned SURGRETEs can provide a concentrated case volume in a resource-constrained setting and challenge the team to consider definitive management algorithms. The cases performed may not necessarily reflect the type and acuity of operations performed in a deployed environment; however, they facilitate repetition of basic skills, team cohesion, and cross-training.

We examined adaptation and evolution of pneumococcus, within nasopharynx and lungs, in an experimental system where the selective pressures associated with transmission were removed. This was achieved by serial passage of pneumococci, separately, in mouse models of nasopharyngeal carriage or pneumonia. Passaged pneumococci became more effective colonizers of the respiratory tract and we observed several examples of potential parallel evolution. The cell wall-modifying glycosyltransferase LafA was under strong selection during lung passage, whereas the surface expressed pneumococcal vaccine antigen gene pvaA and the glycerol-3-phosphate dehydrogenase gene gpsA were frequent targets of mutation in nasopharynx-passaged pneumococci. Camptothecin These mutations were not identified in pneumococci that were separately evolved by serial passage on laboratory agar. We focused on gpsA, in which the same single nucleotide polymorphism arose in two independently evolved nasopharynx-passaged lineages. We describe a new role for this gene in nasopharyngeal carriage and show that the identified single nucleotide change confers resistance to oxidative stress and enhanced nasopharyngeal colonization potential. We demonstrate that polymorphisms in gpsA arise and are retained during human colonization. These findings highlight how within-host environmental conditions can determine trajectories of bacterial evolution. Relative invasiveness or attack rate of pneumococcal lineages may be defined by genes that make niche-specific contributions to bacterial fitness. Experimental evolution in animal infection models is a powerful tool to investigate the relative roles played by pathogen virulence and colonization factors within different host niches.
