Objectives: To assess 24-month outcome differences based on sex in symptomatic femoro-popliteal arterial disease of patients treated with drug-coated balloon (DCB). Background: Peripheral artery disease affects over 12 million people in the United States. Drug-coated balloons have shown to be effective in treating patients with symptomatic femoropopliteal arterial occlusive disease. Debate remains regarding its safety and efficacy in female gender. We investigated the differential treatment effect between genders. Methods: Patients (93 females and 102 males) with symptomatic femoropopliteal arterial disease treated with DCB from November 2014 to November 2015 were included in this retrospective study. We compared the resting ankle-brachial indices (ABIs) and peak systolic velocities (PSVs) by arterial duplex between the male and female patients at 6, 12, and 24 months postintervention. Results: Females had significantly smaller vessels (4.70 ± 0.9, P = .02) and higher body mass index (BMI; 30.0 ± 3.7, P = .002) than males. Females had significantly decreased ABI and PSV at the 6-month (ABI: 0.90 ± 0.15, P = .05 and PSV: 188.30 ± 103.1, P = .02), 12-month (ABI: 0.86 ± 0.15, P < .0001 and PSV: 219.10 ± 100.10, P = .001), and at 24-month (ABI: 0.84 ± 0.2, P = .0001 and PSV: 251.0 ± 135.9, P < .0001) intervals when compared to males. Females had increased clinically driven target lesion revascularization (TLR) at 6 months (females = 8 vs males = 4, P = .22), 12 months (females = 12 vs males = 4, P = .02), and 24 months (females = 14 vs males = 6, P = .03). In simple logistic regression analysis, BMI, age, reference vessel diameter (RVD), and gender were strongly associated with target lesion restenosis. The final model included the above and it produced the following odds ratios (ORs): BMI (OR = 1.07, 95% confidence interval [CI]: 0.98-1.2), age (OR: 1.0, CI: 0.96-1.03), RVD (OR: 1.6, CI: 1.02-2.4), and gender (OR: 3.5, CI: 1.6-7.8). Conclusion: Females treated with DCBs have significantly decreased ABI, PSVs, and an increased rate of TLR than their male counterparts.

Background. Ankle fractures are common and may require open reduction and internal fixation (ORIF). Literature is scarce evaluating the associations of opioid use disorder (OUD) with ORIF postoperative outcomes. This study investigates whether OUD patients have increased (1) costs of care, (2) emergency room visits, and (3) readmission rates. Methods. ORIF patients with a 90-day history of OUD were identified using an administrative claims database. OUD patients were matched (1:4) to controls by age, sex, and medical comorbidities. The Welch t-test determined the significance of cost of care. Logistic regression yielded odds ratios (ORs) for emergency room visits and 90-day readmission rates. Results. A total of 2183 patients underwent ORIF (n = 485 with OUD vs n = 1698 without OUD). OUD patients incurred significantly higher costs of care compared with controls ($5921.59 vs $5128.22, P < .0001). OUD patients had a higher incidence and odds of emergency room visits compared with controls (3.50% vs 0.64%; OR = 5.57, 95% CI = 2.59-11.97, P < .0001). The 90-day readmission rates were not significantly different between patients with and without OUD (8.65% vs 7.30%; OR = 1.20, 95% CI = 0.83-1.73, P = .320). Conclusion. OUD patients have greater costs of care and odds of emergency room visits within 90 days following ORIF. Levels of Evidence: Level III: Retrospective cohort study

Published: April 2020

Background: Sickle cell trait (SCT) has been associated with an increased risk of sudden death in athletes during strenuous exercise. In August 2010, the National Collegiate Athletic Association (NCAA) began requiring athletes to be screened for SCT, provide proof of SCT status, or sign a waiver and launched an educational campaign for athletes, coaches, and medical staff. The impact of this program is unknown. The purpose of this study was to determine the incidence of death associated with sickle cell trait (daSCT) in NCAA athletes before and after legislation. Hypothesis: NCAA SCT legislation will decrease the incidence of daSCT. Study Design: Observational study. Level of Evidence: Level 2. Methods: A database of NCAA athlete deaths from 2000 to 2019 was reviewed for daSCT. A total of 8,309,050 athlete-years (AY) were included. Incidence of death was calculated before and after legislation. Results: The incidence of daSCT in Division I (DI) football athletes before legislation (n = 9) was 1:28,145 AY and after legislation (n = 1) was 1:250,468 AY (relative risk [RR], 0.112; 95% CI, 0.003-0.811; P = 0.022), an 89% reduction in risk after legislation was enacted. The incidence of daSCT in African American DI football athletes before legislation (n = 9) was 1:12,519 AY and after legislation (n = 1) was 1:118,464 AY (RR, 0.106; 95% CI, 0.002-0.763; P = 0.017), also an 89% risk reduction after legislation was enacted. For all NCAA athletes, the incidence of daSCT was 1:489,749 AY before legislation (n = 10) and 1:1,705,780 AY after legislation (n = 2) (RR, 0.288; 95% CI, 0.031-1.347; P = 0.146). Conclusion: The incidence of daSCT in DI football athletes has decreased significantly since legislation was enacted. Cases of daSCT outside of football are rare. It is unclear whether the decrease is related to screening for SCT, education, or both. Clinical Relevance: This is the first evidence that NCAA SCT legislation may save lives.

Background: Sleep and mood are critical factors that contribute to health and wellness and are of particular interest to collegiate athletes who are juggling high physical, academic, and social demands. The aim of this study was to examine how psychological measures, player status, and sex-related factors were associated with perceived sleep quality. Hypothesis: Higher levels of global sleep dysfunction will be related to poor mood and increased anxiety, and there will be differences in sleep dysfunction in male compared with female athletes as well as regarding playing status. Study Design: Prospective cohort study. Level of Evidence: Level 4. Methods: During the 2016 through 2018 National Collegiate Athletic Association (NCAA) seasons, the Pittsburgh Sleep Quality Index (PSQI), Profile of Mood States, and Sports Anxiety Scale–2 questionnaires were administered to 230 soccer athletes at 6 separate time points throughout each season. Results: PSQI results yielded scores ≥5 in 54% of observations. Increased sleep dysfunction was significantly related to decreased vigor and increased tension, depression, anger, fatigue, somatic anxiety, worry, and concentration disruption, although effect sizes (ES) were trivial (ES, –0.03 to 0.15). The odds ratio (OR) of reporting global sleep dysfunction increased by 8%, 9%, and 25% for every 1-unit increase in tension (OR, 1.08; 95% CI, 1.02-1.16; P = 0.015), fatigue (OR, 1.09; 95% CI, 1.03-1.16; P = 0.002), and concentration disruption (OR, 1.25; 95% CI, 1.09-1.45; P = 0.002), respectively. The odds of reporting global sleep dysfunction were 55% lower for males than females (OR, 0.45; 95% CI, 0.25-0.79; P = 0.006). Conclusion: Global sleep dysfunction was prevalent in NCAA soccer players and was related to negative mental health outcomes. Female participants experienced increased odds of reporting global sleep dysfunction. Clinical Relevance: Regular monitoring allows for a greater understanding of the interrelatedness between sleep and mental health in athletes.

AbstractChimeric antigen receptor-T (CAR-T) cell therapy achieves durable responses in patients with relapsed/refractory diffuse large B-cell lymphoma (r/r DLBCL), but may be associated with neurological toxicity (NT). We retrospectively assessed differences and concordance among 3 available grading scales (the National Cancer Institute Common Terminology Criteria for Adverse Events v4.03 [CTCAE], modified CAR-T Related Encephalopathy Syndrome [mCRES], and American Society for Transplantation and Cellular Therapy [ASTCT] scales) applied to the same set of NT data from the JULIET (A Phase 2, Single Arm, Multicenter Trial to Determine the Efficacy and Safety of CTL019 in Adult Patients With Relapsed or Refractory DLBCL) trial. Individual patient-level NT data from the phase 2, single-group, global, pivotal JULIET trial (NCT02445248) were retrospectively and independently graded, using CTCAE, ASTCT, and mCRES, by 4 medical experts with experience managing patients with 3 different CD19-targeted CAR constructs. According to the US Food and Drug Administration definition of NT using CTCAE, 62 of 106 patients infused with tisagenlecleucel had NT as of September 2017. Among 111 patients infused with tisagenlecleucel (as of December 2017), the 4 experts identified 50 patients (45%) who had any-grade NT per CTCAE, 19 (17%) per mCRES, and 19 (17%) per ASTCT. Reevaluation according to the mCRES/ASTCT criteria downgraded 31 events deemed NT by CTCAE to grade 0. This is the first study to retrospectively apply CTCAE, mCRES, and ASTCT criteria to the same patient data set. We conclude that CTCAE v4.03 was not designed for, and is suboptimal for, grading CAR-T cell therapy-associated NT. The CRES and ASTCT scales, which measure immune effector cell-associated neurotoxicity syndrome, offer more accurate assessments of NT after CAR-T cell therapy.

Abstract
Background
Oxidative stress results in cell apoptosis/death and plays a detrimental role in disease development and progression. Stressors alter the miRNA expression profile and miRNAs play a role in the cell response to stress. We previously showed that miR-711 is significantly over-expressed in extended cold ischemia reperfusion injured hearts in heart transplant. In this study, we aimed to investigate the role of miR-711 in cardiac cell damage in response to oxidative stress and how miR-711 is regulated.

Methods
Rat cardiac cell line H9c2 cells were cultured and exposed to oxidative conditions (Antimycin A (AA), H2O2, CoCl2, or cold hypoxia/reoxygenation (H/R)) in vitro. H9c2 cells were transfected with miR-711 mimics, miR-711 inhibitors, or small interference RNA, using transfection reagents. The expression of miR-711 was measured by quantitative reverse transcriptase-polymerase chain reaction (qRT-PCR). Cell apoptosis/death was detected by flow cytometry and an IncuCyte system. Mitochondrial damage was detected by measuring the mitochondria membrane potential by flow cytometry. Gene expression was detected by qRT-PCR at the mRNA level and Western blotting and immunocytochemistry staining at the protein level.

Results
We found that miR-711 was significantly up-regulated in cells treated with H2O2, AA, CoCl2, and cold H/R. Over-expression of miR-711 increased cell apoptosis/death induced by AA and H/R whereas cell death was reduced by miR-711 inhibitors. MiR-711 induced cell death through negative regulation of angiopoietin 1 (Ang-1), fibroblast growth factor 14 (FGF14) and calcium voltage-gated channel subunit alpha1C (Cacna1c) genes. Both knockdown of hypoxia inducible factor 1α (HIF-1α) and inactivation of the nuclear factor kappa-light-chain-enhancer of activated B cells (NFКB) pathway inhibited over-expression of miR-711.

Conclusion
Oxidative stress increases the expression of miR-711. Over-expression of miR-711 induces cell apoptosis/death. HIF-1α and NFКB regulate miR-711 in H9c2 cells during oxidative stress. miR-711 is a new target for preventing oxidative stress.

Abstract
Background
Jatropha curcas, a tropical shrub, is a promising biofuel crop, which produces seeds with high content of oil and protein. To better understand the maturation process of J. curcas seeds and to improve its agronomic performance, a two-step approach was performed in six different maturation stages of seeds: 1) generation of the entire transcriptome of J. curcas seeds using 454-Roche sequencing of a cDNA library, 2) comparison of transcriptional expression levels using a custom Agilent 8x60K oligonucleotide microarray.

Results
A total of 793,875 high-quality reads were assembled into 19,382 unique full-length contigs, of which 13,507 could be annotated with Gene Ontology (GO) terms. Microarray data analysis identified 9111 probes (out of 57,842 probes), which were differentially expressed between the six maturation stages. The expression results were validated for 75 selected transcripts based on expression levels, predicted function, pathway, and length.
Result from cluster analyses showed that transcripts associated with fatty acid, flavonoid, and phenylpropanoid biosynthesis were over-represented in the early stages, while those of lipid storage were over-represented in the late stages. Expression analyses of different maturation stages of J. curcas seed showed that most changes in transcript abundance occurred between the two last stages, suggesting that the timing of metabolic pathways during seed maturation in J. curcas occurs in late stages. The co-expression results showed that the hubs (CB5-D, CDR1, TT8, DFR, HVA22) with the highest number of edges, associated with fatty acid and flavonoid biosynthesis, are showing a decrease in their expression during seed maturation. Furthermore, seed development and hormone pathways are significantly well connected.

Conclusion
The obtained results revealed differentially expressed sequences (DESs) regulating important pathways related to seed maturation, which could contribute to the understanding of the complex regulatory network during seed maturation with the focus on lipid, flavonoid and phenylpropanoid biosynthesis. This study provides detailed information on transcriptional changes during J. curcas seed maturation and provides a starting point for a genomic survey of seed quality traits. The results highlighted specific genes and processes relevant to the molecular mechanisms involved in Jatropha seed maturation. These data can also be utilized regarding other Euphorbiaceae species.

Abstract
Background
Copy number variation is an important class of genomic variation that has been reported in 75% of the human genome. However, it is underreported in African populations. Copy number variants (CNVs) could have important impacts on disease susceptibility and environmental adaptation. To describe CNVs and their possible impacts in Africans, we sequenced genomes of 232 individuals from three major African ethno-linguistic groups: (1) Niger Congo A from Guinea and Côte d’Ivoire, (2) Niger Congo B from Uganda and the Democratic Republic of Congo and (3) Nilo-Saharans from Uganda. We used GenomeSTRiP and cn.MOPS to identify copy number variant regions (CNVRs).

Results
We detected 7608 CNVRs, of which 2172 were only deletions, 2384 were only insertions and 3052 had both. We detected 224 previously un-described CNVRs. The majority of novel CNVRs were present at low frequency and were not shared between populations. We tested for evidence of selection associated with CNVs and also for population structure. Signatures of selection identified previously, using SNPs from the same populations, were overrepresented in CNVRs. When CNVs were tagged with SNP haplotypes to identify SNPs that could predict the presence of CNVs, we identified haplotypes tagging 3096 CNVRs, 372 CNVRs had SNPs with evidence of selection (iHS > 3) and 222 CNVRs had both. This was more than expected (p < 0.0001) and included loci where CNVs have previously been associated with HIV, Rhesus D and preeclampsia. When integrated with 1000 Genomes CNV data, we replicated their observation of population stratification by continent but no clustering by populations within Africa, despite inclusion of Nilo-Saharans and Niger-Congo populations within our dataset.

Conclusions
Novel CNVRs in the current study increase representation of African diversity in the database of genomic variants. Over-representation of CNVRs in SNP signatures of selection and an excess of SNPs that both tag CNVs and are subject to selection show that CNVs may be the actual targets of selection at some loci. However, unlike SNPs, CNVs alone do not resolve African ethno-linguistic groups. Tag haplotypes for CNVs identified may be useful in predicting African CNVs in future studies where only SNP data is available.

Published: April 2020

Abstract
Background
The aim was to evaluate the changes of 16S rDNA sequencing and LC-MS metabolomics in breast cancer and explore the growth inhibition of breast cancer cells by Faecalibacterium prausnitzii.

Results
Total 49 significantly different flora and 26 different metabolites were screened between two groups, and the correlation was calculated. Relative abudance of Firmicutes and Bacteroidetes were decreased, while relative abundance of verrucomicrobla, proteobacteria and actinobacteria was increased in breast cancer group. Differentially expressed metabolites were mainly enriched in pathways such as linoleic acid metabolism, retrograde endocannabinoid signaling, biosynthesis of unsaturated fatty acids, choline metabolism in cancer and arachidonic acid metabolism. Lipid upregulation was found in breast cancer patients, especially phosphorocholine. The abundance of Faecalibacterium was reduced in breast cancer patients, which was negatively correlated with various phosphorylcholines. Moreover, Faecalibacterium prausnitzii, the most well-known species in Faecalibacterium genus, could inhibit the secretion of interleukin-6 (IL-6) and the phosphorylation of Janus kinases 2 (JAK2)/signal transducers and activators of transcription 3 (STAT3) in breast cancer cells. Faecalibacterium prausnitzii also suppressed the proliferation and invasion and promoted the apoptosis of breast cancer cells, while these effects disappeared after adding recombinant human IL-6.

Conclusions
Flora-metabolites combined with the flora-bacteria (such as Faecalibacterium combined with phosphorocholine) might a new detection method for breast cancer. Faecalibacterium may be helpful for prevention of breast cancer. Faecalibacterium prausnitzii suppresses the growth of breast cancer cells through inhibition of IL-6/STAT3 pathway.

Abstract
Background
Long term β-blocker therapy after myocardial infarction (MI) reduces mortality and recurrent MI but evidence for this treatment predates contemporary acute coronary care. β-blocker treatment is a key quality of care indicator in the Swedish national quality register for acute coronary care, Riks-HIA. Between 2011 and 2015 a declining number of MI-patients discharged with a β-blocker from the coronary care unit (CCU) at Helsingborg and other hospitals was reported. This retrospective observational study aimed to investigate the causes for discharge without a β-blocker and relate it to outcome, compared to patients discharged with a β-blocker.

Methods
MI-patients registered in Riks-HIA discharged without β-blocker during 2011–2015 (no-β-group) and a control group (β-group) comprised of patients discharged with β-blocker treatment between January 1 to December 31, 2013, were matched by RIKS-HIA criteria for β-blocker use. Clinical characteristics, date of death, readmission for MI, other cardiovascular events were collected from Riks-HIA and medical records.

Results
The no-β-group included 141 patients, where 65.2% had a justified reason for non-β-blocker use. The β-group included 206 patients. There was no difference in cardiovascular risk factor profile. There were a trend towards a higher number of readmissions for MI in the no-β-group was (n = 8 (5.7%) vs n = 2 (1.0%), p = 0.02), but not mortality (6 (4.3%) vs 2 (1.0%), p = 0.07) and combined readmission for angina pectoris, heart failure, arrhythmias or stroke/TIA (n = 23 (16.3%) vs n = 25 (12.1%), p = 0.27).

Conclusion
A majority of the patients in the no-β-group had a justified absence of a β-blocker. β-blocker treatment post-MI showed a trend towards fewer readmissions for MI. But important quality information is lacking to make a firm conclusion of the effect on outcome.
