Abstract
Aging is characterized by declining health that results in decreased cellular resilience and neuromuscular function. The relationship between lifespan and health, and the influence of genetic background on that relationship, has important implications in the development of pharmacological anti-aging interventions. Here we assessed swimming performance as well as survival under thermal and oxidative stress across a nematode genetic diversity test panel to evaluate health effects for three compounds previously studied in the Caenorhabditis Intervention Testing Program and thought to promote longevity in different ways - NP1 (nitrophenyl piperazine-containing compound 1), propyl gallate, and resveratrol. Overall, we find the relationships among median lifespan, oxidative stress resistance, thermotolerance, and mobility vigor to be complex. We show that oxidative stress resistance and thermotolerance vary with compound intervention, genetic background, and age. The effects of tested compounds on swimming locomotion, in contrast, are largely species-specific. In this study, thermotolerance, but not oxidative stress or swimming ability, correlates with lifespan. Notably, some compounds exert strong impact on some health measures without an equally strong impact on lifespan. Our results demonstrate the importance of assessing health and lifespan across genetic backgrounds in the effort to identify reproducible anti-aging interventions, with data underscoring how personalized treatments might be required to optimize health benefits.

Abstract
The Caenorhabditis Intervention Testing Program (CITP) is an NIH-funded research consortium of investigators who conduct analyses at three independent sites to identify chemical interventions that reproducibly promote health and lifespan in a robust manner. The founding principle of the CITP is that compounds with positive effects across a genetically diverse panel of Caenorhabditis species and strains are likely engaging conserved biochemical pathways to exert their effects. As such, interventions that are broadly efficacious might be considered prominent compounds for translation for pre-clinical research and human clinical applications. Here, we report results generated using a recently streamlined pipeline approach for the evaluation of the effects of chemical compounds on lifespan and health. We studied five compounds previously shown to extend C. elegans lifespan or thought to promote mammalian health: 17α-estradiol, acarbose, green tea extract, nordihydroguaiaretic acid, and rapamycin. We found that green tea extract and nordihydroguaiaretic acid extend Caenorhabditis lifespan in a species-specific manner. Additionally, these two antioxidants conferred assay-specific effects in some studies-for example, decreasing survival for certain genetic backgrounds in manual survival assays in contrast with extended lifespan as assayed using automated C. elegans Lifespan Machines. We also observed that GTE and NDGA impact on older adult mobility capacity is dependent on genetic background, and that GTE reduces oxidative stress resistance in some Caenorhabditis strains. Overall, our analysis of the five compounds supports the general idea that genetic background and assay type can influence lifespan and health effects of compounds, and underscores that lifespan and health can be uncoupled by chemical interventions.

Abstract
Purpose Opioid consumption after total knee arthroplasty (TKA) remains a challenge with single injection nerve blocks even with common local anesthetic adjuvants dexamethasone (DEX). This study aimed to investigate the effects of adding methylprednisolone acetate (MPA) to adductor canal blocks (ACB) and interspace between the popliteal artery and capsule of the posterior knee (iPACK) blocks on postoperative opioid consumption. Methods A retrospective analysis was conducted on 100 consecutive TKA patients equally assigned into two groups, with one group receiving DEX through ACB and iPACK block and the other group receiving DEX and methylprednisolone acetate (DEX/MPA) through the same nerve blocks. The primary outcome was cumulative opioid consumption (oral milligram morphine equivalent, OME) during hospitalization for up to three days. Secondary outcomes included daily opioid consumption, highest rest and active pain scores, prosthetic knee joint active range of motion (AROM), laboratory studies including fasting serum glucose (FSG) and white blood cell count (WBC) on each postoperative day (POD), and length of hospital stay. Results Cumulative opioid consumption was significantly lower in the DEX/MPA group vs DEX group (median difference (95% CI) = -45.3 (-80.5 to -10), P = 0.011). The highest rest and active pain scores were both significantly lower in the DEX/MPA group than in DEX group on POD 2 (least square mean difference (95% CI) = -1.3 (-2.3 to -0.4), P = 0.005 and -0.9 (-1.8 to -0.1), P = 0.031, respectively). Except on POD 1, FSG values were significantly lower in the DEX/MPA group (median difference (95% CI) = -22.5 (-36 to -8.9), P = 0.001). AROM, WBC, and length of stay were comparable between both groups. Conclusion Compared to perineural DEX alone, the addition of MPA further decreases postoperative opioid consumption without clinically significant changes on FSG and WBC. Level of Evidence III.

Abstract
Metformin, the most commonly prescribed anti‐diabetes medication, has multiple reported health benefits, including lowering the risks of cardiovascular disease and cancer, improving cognitive function with age, extending survival in diabetic patients, and, in several animal models, promoting youthful physiology and lifespan. Due to its longevity and health effects, metformin is now the focus of the first proposed clinical trial of an anti‐aging drug—the Targeting Aging with Metformin (TAME) program. Genetic variation will likely influence outcomes when studying metformin health effects in human populations. To test for metformin impact in diverse genetic backgrounds, we measured lifespan and healthspan effects of metformin treatment in three Caenorhabditis species representing genetic variability greater than that between mice and humans. We show that metformin increases median survival in three C. elegans strains, but not in C. briggsae and C. tropicalis strains. In C. briggsae, metformin either has no impact on survival or decreases lifespan. In C. tropicalis, metformin decreases median survival in a dose‐dependent manner. We show that metformin prolongs the period of youthful vigor in all C. elegans strains and in two C. briggsae strains, but that metformin has a negative impact on the locomotion of C. tropicalis strains. Our data demonstrate that metformin can be a robust promoter of healthy aging across different genetic backgrounds, but that genetic variation can determine whether metformin has positive, neutral, or negative lifespan/healthspan impact. These results underscore the importance of tailoring treatment to individuals when testing for metformin health benefits in diverse human populations.

Abstract
Abstract
Background
Cardiovascular disease (CVD) remains the leading cause of death globally, taking an estimated 18 million lives each year. Digital health interventions (DHI), such as wearables and smartphone applications, have shown promise in CVD detection, prevention, and management. However, there are scarce data regarding clinician perspectives on the utility of DHI and identification of key elements to support adoption in clinical practice.
Method
In this cross-sectional study, a web-based survey was administered to 107 clinicians directly involved in the care of cardiac inpatients across multiple academic health care systems in the United States, between January 2020 and March 2021. Participants (1) reported their perceptions of DHI impact on their ability to care for patients with CVD, (2) rated the importance of factors related to DHI adoption, and (3) shared perspectives on using DHI for secondary CVD prevention to support guideline-directed medical therapy in patients after acute myocardial infarction. Descriptive statistics were analyzed and summarized as frequencies with percentages.
Results
Among survey respondents, 41% were women; 22% specialized in cardiovascular medicine; and 31% were practicing attendings (Table). Overall, 92% (86/94) of respondents believed that DHI would be important in offering advantages in cardiovascular patient care (Figure). Increasing patient adherence was reported as the most important benefit of DHI adoption by 39% of clinicians, followed by improvement in the patient-clinician relationship (29%), enabling remote care (18%), and improving patient experience (14%). Clinicians under age 40 years old, cardiologists, and internists were the groups more likely to consider DHI important in remote patient care, disease monitoring, and tele-visits, as compared to clinicians over age 40 years old or in other clinical specialties.
Conclusion
Our results highlight clinician perspectives on the advantages of DHI and the potential for its adoption for secondary prevention of CVD.

Abstract
Recent research has shown an association between monthly law enforcement drug seizure events and accidental drug overdose deaths using cross-sectional data in a single state, whereby increased seizures correlated with more deaths. In this study, we conduct statistical analysis of street-level data on law enforcement drug seizures, along with street-level data on fatal and non-fatal overdose events, to determine possible micro-level causal associations between opioid-related drug seizures and overdoses. For this purpose, we introduce a novel, modified two-process Knox test that controls for self-excitation to measure clustering of overdoses nearby in space and time following law enforcement seizures. We observe a small, but statistically significant (
p
< 0.001), effect of 17.7 excess non-fatal overdoses per 1000 law enforcement seizures within three weeks and 250 m of a seizure. We discuss the potential causal mechanism for this association along with policy implications.

Abstract
The defensive mucus produced by the slug Arion subfuscus is tough and remarkably sticky. It spreads rapidly and adheres strongly to a wide range of surfaces. The adhesion is equally strong on wettable (glass) and non-wettable (plastic) surfaces. The adhesion appears to depend on a group of proteins that adsorb equally well to a wide range of different natural and artificial surfaces. Prominent among these proteins were those that distinguish the adhesive secretion from the non-adhesive mucus. The adhesive proteins were not washed off by non-ionic detergent, nor was the adhesion of the glue as a whole affected by this treatment. In contrast, high salt concentrations washed the most abundant adhesive proteins off the surfaces, and correspondingly weakened the glue's attachment. The most abundant of the adhesive proteins were C-lectins, which appear to form heterotrimers. These and other lectin-like proteins in slug glue have a high proportion of aromatic amino acids at conserved locations, and are relatively small and often basic. The aromatic and cationic side chains may provide a powerful combination promoting and maintaining surface adhesion.

Abstract
As medication experts, clinical pharmacists play an active and dynamic role in a medication shortage response. Supplementing existing guidelines with an actionable framework of discrete activities to support effective medication shortage responses can expand the scope of pharmacy practice and improve patient care. Dissemination of best practices and illustrative, networked examples from health systems can support the adoption of innovative solutions. In this descriptive report, we document the translation of published shortage mitigation guidelines into system success through broad pharmacist engagement and the adaption and implementation of targeted strategies. The profound, wide‐reaching medication shortages that accompanied the coronavirus disease 2019 (COVID‐19) pandemic are used to highlight coordinated but distinct practices and how they have been combined to expand the influence of the pharmacy enterprise.

Abstract
BACKGROUND There are currently few effective drugs to treat the leg symptoms of peripheral arterial disease (PAD). Previous studies have suggested that the nutraceutical, quercetin, can improve exercise performance and reduce pain sensitivity in healthy mice and improve blood supply in a rodent model of acute hind-limb ischaemia. These models may not be relevant to people with PAD. The aim of this study was to examine the effect of quercetin on exercise performance, physical activity and blood supply in a novel mouse model of sustained hind-limb ischaemia. METHODS Hind-limb ischaemia was induced in 6-month-old male apolipoprotein E-deficient mice using a novel two-stage surgical procedure. Five days after induction of ischaemia, mice were allocated to commence dietary quercetin or a control diet for 4 weeks. The primary outcome was exercise performance evaluated using a treadmill test. Other outcomes included physical activity, estimated by an open field test, and hind-limb blood supply, assessed by laser Doppler monitoring. RESULTS A sustained reduction in relative limb blood supply (P < 0.001) was achieved consistently in all 48 mice before allocation to a control (n = 24) or quercetin (n = 24) diet. Quercetin did not improve exercise performance (P = 0.785), physical activity (P = 0.151) or relative limb blood supply (P = 0.954) over the 4-week assessment period. CONCLUSION These data suggest that quercetin does not improve exercise performance, physical activity or limb blood supply in mice with sustained hind-limb ischaemia, and therefore is unlikely be an effective treatment for PAD.

Abstract
The goal of the Caenorhabditis Intervention Testing Program is to identify robust and reproducible pro-longevity interventions that are efficacious across genetically diverse cohorts in the Caenorhabditis genus. The project design features multiple experimental replicates collected by three different laboratories. Our initial effort employed fully manual survival assays. With an interest in increasing throughput, we explored automation with flatbed scanner-based Automated Lifespan Machines (ALMs). We used ALMs to measure survivorship of 22 Caenorhabditis strains spanning three species. Additionally, we tested five chemicals that we previously found extended lifespan in manual assays. Overall, we found similar sources of variation among trials for the ALM and our previous manual assays, verifying reproducibility of outcome. Survival assessment was generally consistent between the manual and the ALM assays, although we did observe radically contrasting results for certain compound interventions. We found that particular lifespan outcome differences could be attributed to protocol elements such as enhanced light exposure of specific compounds in the ALM, underscoring that differences in technical details can influence outcomes and therefore interpretation. Overall, we demonstrate that the ALMs effectively reproduce a large, conventionally scored dataset from a diverse test set, independently validating ALMs as a robust and reproducible approach toward aging-intervention screening.

Abstract
NAD(P)H: quinone oxidoreductase (NQO1) is essential for cell defense against reactive oxidative species, cancer, and metabolic stress. Recently, NQO1 was found in ribonucleoprotein (RNP) complexes, but NQO1-interacting mRNAs and the functional impact of such interactions are not known. Here, we used ribonucleoprotein immunoprecipitation (RIP) and microarray analysis to identify comprehensively the subset of NQO1 target mRNAs in human hepatoma HepG2 cells. One of its main targets, SERPINA1 mRNA, encodes the serine protease inhibitor α-1-antitrypsin, A1AT, which is associated with disorders including obesity-related metabolic inflammation, chronic obstructive pulmonary disease (COPD), liver cirrhosis and hepatocellular carcinoma. Biotin pulldown analysis indicated that NQO1 can bind the 3' untranslated region (UTR) and the coding region (CR) of SERPINA1 mRNA. NQO1 did not affect SERPINA1 mRNA levels; instead, it enhanced the translation of SERPINA1 mRNA, as NQO1 silencing decreased the size of polysomes forming on SERPINA1 mRNA and lowered the abundance of A1AT. Luciferase reporter analysis further indicated that NQO1 regulates SERPINA1 mRNA translation through the SERPINA1 3'UTR. Accordingly, NQO1-KO mice had reduced hepatic and serum levels of A1AT and increased activity of neutrophil elastase (NE), one of the main targets of A1AT. We propose that this novel mechanism of action of NQO1 as an RNA-binding protein may help to explain its pleiotropic biological effects.

Abstract
INTRODUCTION Currently available stem cell mobilizing regimens (G-CSF +/- chemotherapy) show high failure rates, especially in heavily pretreated patients. Plerixafor, a new stem cell mobilizing agent blocking the CXCR4-SDF-1 interaction, offers a new strategy for stem cell mobilization, especially in poor mobilizers.This study reports on the outcome of the Belgian compassionate use program (CUP). MATERIALS AND METHODS Between July 2008 and July 2009, 14 Belgian transplant centres participated in plerixafor CUP. In total, 22 poor stem cell mobilizers were included. Patients who previously failed stem cell mobilization received a combination of G-CSF (morning of Day 1-5) and plerixafor (evening of Day 4). Apheresis was performed on Day 5. G-CSF, plerixafor and apheresis were continued until at least 2 x 10(6)/kg CD34+ cells were obtained in a maximum of 3 collections. RESULTS A mean of 2 plerixafor administrations was needed to reach > or = 2 x 10(6)/kg CD34+ cells. The overall cumulative success rate (defined as the proportion of patients achieving a successful collection after a maximum of 3 apheresis days) was 64%. Half of the heavily pretreated patients ( 3 prior chemotherapy regimens) could be mobilized successfully. Patients who received < or = 2 prior chemotherapy regimens mobilized successfully in 75% of the cases. Thirteen patients (59.1%) underwent autologous stem cell transplantation with normal neutrophil and platelet recovery times. CONCLUSION For patients failing previous mobilization attempts, the combination of plerixafor and G-CSF is a successful mobilizing strategy, even in poor mobilizers who received > or = 3 prior chemotherapy regimens.

Abstract
BACKGROUND Amprenavir, a human immunodeficiency virus type 1 (HIV-1) protease inhibitor, is approved for the treatment of HIV infection in combination with other antiretroviral agents in treatment-naive and experienced patients. Amprenavir is generally well tolerated. However, cutaneous hypersensitivity reactions to amprenavir occur in up to 28% of patients, with treatment discontinuation required in 3% of cases. OBJECTIVE To report successful desensitization to amprenavir after the occurrence of a maculopapular exanthem in an HIV-infected patient with late-stage disease and limited antiretroviral treatment options. METHODS Incremental doses of 0.025, 0.1, 0.25, 1, 2.5, 7.5, 25, 50, 100, 300, 600, and 1,200 mg of amprenavir oral solution were administered via percutaneous endoscopic gastrostomy tube at 20- to 30-minute intervals. RESULTS The patient successfully tolerated amprenavir desensitization and has continued therapy without recurrence of rash at 19 months of follow-up. CONCLUSION Desensitization may permit the continued use of amprenavir in HIV-positive patients with a history of amprenavir-induced maculopapular eruptions who have limited alternate treatment options.

Abstract
A cDNA clone encoding the polypeptide for Plasmodium falciparum adenine nucleotide translocator (ANT) was isolated by screening a cDNA library with a 150 base pair fragment of genomic DNA which had been enzymatically amplified using two oligonucleotide primers designed from conserved regions of ANT's from other sources. The deduced amino acid sequence of the P. falciparum cloned insert was highly homologous to ANT of other organisms. Features of the sequence are discussed with reference to the targeting and membrane insertion of ANT. The protein has a molecular mass of 35 kDa as predicted from the 303 amino acids encoded in the open reading frame.

Abstract
The microtubule associated protein called tau, found primarily in neurons, was detected in a human neuroblastoma cell line, LAN-5. Cells treated with retinoic acid (2.0 x 10(-5) M) differentiate and acquire processes similar to neurons. Differentiated and logarithmically growing undifferentiated cells were exposed to varying doses of doxorubicin (an anthracycline chemotherapeutic antibiotic). While doxorubicin was lethal to many undifferentiated dividing cells, it was not as damaging to differentiated cells. After 2 to 4 days of doxorubicin treatment, the cells were harvested, the protein concentration determined and SDS-PAGE performed. Proteins were blotted onto nitrocellulose paper and immunostained with either a rabbit antiserum or mouse monoclonal antibody to tau. Undifferentiated LAN-5 cells treated with 4.0 x 10(-8) M doxorubicin for 4 days and cells treated with 8.0 x 10(-8) M doxorubicin for 2 days displayed a distinct lower band (just below the 50 kd marker) that was either absent or very faint in untreated controls.
