Abstract
Most commercial peach [Prunus persica (L.) Batsch] cultivars have leaves with extrafloral nectaries (EFNs). Breeders have selected this character over time, as they observed that the eglandular phenotype resulted in high susceptibility to peach powdery mildew, a major disease of peach trees. EFNs are controlled by a Mendelian locus (E), mapped on chromosome 7. However, the genetic factor underlying E was unknown. In order to address this point, we developed a mapping population of 833 individuals derived from the selfing of “Malo Konare”, a Bulgarian peach cultivar, heterozygous for the trait. This progeny was used to investigate the E-locus region, along with additional resources including peach genomic resequencing data, and 271 individuals from various origins used for validation. High-resolution mapping delimited a 40.6 kbp interval including the E-locus and four genes. Moreover, three double-recombinants allowed identifying Prupe.7G121100, a LMI1-like homeodomain leucine zipper (HD-Zip) transcription factor, as a likely candidate for the trait. By comparing peach genomic resequencing data from individuals with contrasted phenotypes, a MITE-like transposable element of the hAT superfamily (mMoshan) was identified in the third exon of Prupe.7G121100. It was associated with the absence or globose phenotype of EFNs. The insertion of the transposon was positively correlated with enhanced expression of Prupe.7G121100. Furthermore, a PCR marker designed from the sequence-variants, allowed to properly assign the phenotypes of all the individuals studied. These findings provide valuable information on the genetic control of a trait poorly known so far although selected for a long time in peach.

Abstract
Acidity is an important factor influencing the organoleptic quality of apple fruits. In this study, an apple pyrophosphate-energized proton pump (PEPP) gene was isolated and designated MdMa12. On the basis of a phylogenetic analysis in Rosaceae species, PEPP genes were divided into three groups, with apple PEPP genes most closely related to pear PEPP genes. Gene expression analysis revealed that high malic acid content was generally accompanied by high MdMa12 expression levels. Moreover, MdMa12 was mainly expressed in the fruit. A subcellular localization analysis suggested that MdMa12 is a mitochondrial protein. The ectopic expression and overexpression of MdMa12 in “Micro-Tom” tomato and apple calli, respectively, increased the malic acid content. One (MDH12) of four malate dehydrogenase genes highly expressed in transgenic apple calli was confirmed to encode a protein localized in mitochondria. The overexpression of MDH12 increased the malate content in apple calli. Furthermore, MdMa12 overexpression increased MdDTC1, MdMa1, and MdMa10 expression levels, which were identified to transport malate. These findings imply that MdMa12 has important functions related to apple fruit acidity. Our study explored the regulatory effects of mitochondria on the complex mechanism underlying apple fruit acidity.
Assessing non-protein nitrogen sources in commercial dry dog foods
Authors: Geiger Andrea K , Weber Lynn P 
Published: January 2022

AbstractProtein is a macronutrient required by dogs for growth and maintenance metabolism. However, a portion of the crude protein listed on pet foods may actually arise from non-digestible organic nitrogen or potentially toxic inorganic non-protein nitrogen sources. Neither non-protein source is retained or used by the animal. However, these compounds may result in adverse effects such as methemoglobin formation and increased oxidative stress or potentially beneficial effects such as improved vascular distensibility and decreased inflammation. To analyze nitrogen retention and screen for non-protein nitrogen, four commercial, dry kibble dog foods and one laboratory-made diet were evaluated and then fed to beagles during two separate feeding trials. During the first trial, dogs were randomly assigned each diet (n = 4 dogs/diet) and fed chromium oxide-coated diets for 48 h, followed by total urine and marked fecal collection, as well as plasma collection for total nitrogen, nitrate, ammonia, and urea determination. The amount of nitrogen retained (93%–96%) did not differ among commercial diets. Protein total tract apparent digestibility (TTAD) ranged from 69% to 84%, with the high protein diets significantly higher than the laboratory-made and mid-ranged diets (1-way ANOVA: P &lt; 0.05). The high protein diet also contained the highest concentration of nitrate with subsequent elevations in plasma nitrotyrosine levels (indicator of oxidative stress). During the second trial, eight dogs (n = 8) were fed the same diets for 6 d, after which echocardiography was completed with blood, urine, and feces collected. For health end-points, methemoblobin, plasma nitrotyrosine, and C-reactive protein (CRP; indicator of inflammation) levels were measured. Methemoglobin levels were significantly lower in the high protein diet (P &gt; 0.05), possible due to the stimulation of methemoglobin reductase while nitrotyrosine was unchanged and CRP was undetectable. Furthermore, there was a positive relationship between crude protein, crude fat (simple linear regression: P = 0.02, r2 &gt; 0.6), price (P = 0.08, r2 &gt; 0.6), and caloric density (P = 0.11, r2 &gt; 0.6). There were no significant cardiovascular differences among any of the diets (P &gt; 0.05). Ultimately, this study shows that in commercial diets, price does reflect protein content but that feeding dogs high protein diets for a long period of time may provide an excess in calories without a change in cardiovascular function or detectable increases in inflammation.

Published: January 2022

Background
The interscalene nerve block provides analgesia for shoulder surgery. To extend block duration, provide adequate analgesia, and minimize opioid consumption, the use of adjuvants such as dexamethasone as well as the application of perineural liposomal bupivacaine have been proposed. This randomized, double-blinded, noninferiority trial hypothesized that perineural liposomal bupivacaine is noninferior to standard bupivacaine with perineural dexamethasone in respect to average pain scores in the first 72 h after surgery.

Methods
A total of 112 patients undergoing ambulatory shoulder surgery were randomized into two groups. The liposomal bupivacaine group received a 15-ml premixed admixture of 10 ml of 133 mg liposomal bupivacaine and 5 ml of 0.5% bupivacaine (n = 55), while the bupivacaine with dexamethasone group received an admixture of 15 ml of 0.5% standard bupivacaine with 4 mg dexamethasone (n = 56), respectively. The primary outcome was the average numerical rating scale pain scores at rest over 72 h. The mean difference between the two groups was compared against a noninferiority margin of 1.3. Secondary outcomes were analgesic block duration, motor and sensory resolution, opioid consumption, numerical rating scale pain scores at rest and movement on postoperative days 1 to 4 and again on postoperative day 7, patient satisfaction, readiness for postanesthesia care unit discharge, and adverse events.

Results
A liposomal bupivacaine group average numerical rating scale pain score over 72 h was not inferior to the bupivacaine with dexamethasone group (mean [SD], 2.4 [1.9] vs. 3.4 [1.9]; mean difference [95% CI], –1.1 [–1.8, –0.4]; P < 0.001 for noninferiority). There was no significant difference in duration of analgesia between the groups (26 [20, 42] h vs. 27 [20, 39] h; P = 0.851). Motor and sensory resolutions were similar in both groups: 27 (21, 48) h versus 27 (19, 40) h (P = 0.436) and 27 [21, 44] h versus 31 (20, 42) h (P = 0.862), respectively. There was no difference in opioid consumption, readiness for postanesthesia care unit discharge, or adverse events.

Conclusions
Interscalene nerve blocks with perineural liposomal bupivacaine provided effective analgesia similar to the perineural standard bupivacaine with dexamethasone. The results show that bupivacaine with dexamethasone can be used interchangeably with liposomal bupivacaine for analgesia after shoulder surgery.

Published: January 2022

Abstract
Acute pancreatitis (AP) is a common clinical gastrointestinal disorder with a high mortality rate for severe AP and lacks effective clinical treatment, which leads to considerable comorbidity and financial burden. Traditional Chinese medicine (TCM) has had the unique advantage of treating AP for a long time in China. Clinically, TCM formulas such as Da-cheng-qi decoction, Chai-qin-cheng-qi decoction, Qing-yi decoction, Da-chai-hu decoction, and Da-huang-fu-zi decoction are widely administrated to AP patients. All of these TCM formulas can improve gastrointestinal function, regulate the inflammatory response, and enhance immunity, thus preventing complications, reducing the mortality rate and financial burden. This review will summarize the pharmacological activities and mechanisms of TCM formulas in alleviating AP.

Published: January 2022

Objective
Resection of the primary (RP) in metastatic neuroendocrine tumor (NET) is controversial. The aim was to evaluate survival outcomes for RP in metastatic NET patients.

Methods
Data were obtained from US hospitals at the National Cancer Database between 2004 and 2014. χ2, analysis of variance tests, univariate, and multivariate cox proportional hazards models were evaluated. Kaplan-Meier curves and log-rank tests conducted to compare the survival difference of patient characteristics.

Results
A total of 2361 patients were identified. The mean age was 62.1 years (standard deviation, 13 years), male-to-female ratio 1:1; 33% were small intestine, 26.3% pancreas, and 24.4% lung; 69.6% were well-differentiated; and 42.5% underwent RP. The 5-year overall survival (OS) was significantly improved for patients who underwent RP in small intestine (5-year OS, 63.9% vs 44.2%), lung (5-year OS, 65.4% vs 20.2%), and pancreas tumors (5-year OS, 75.6% vs 30.6%). On multivariate analysis, RP (hazard ratio, 0.46; 95% confidence interval, 0.29–0.73; P < 0.001), female, year of diagnosis 2010–2014, margin, Charlson-Deyo score less than 2, and age less than 51 years, were associated with better OS.

Conclusions
Resection of the primary in metastatic well-differentiated NET is associated with improved OS compared with no RP.
Elevated Intracranial Pressure in Patients with Craniosynostosis by Optical Coherence Tomography

Published: January 2022

Background:
Craniosynostosis may lead to elevated intracranial pressure, which may be implicated with impaired neurocognitive development. However, accurately measuring intracranial pressure is challenging, and patterns in craniosynostosis patients are poorly characterized. Spectral-domain optical coherence tomography may enable noninvasive assessment of intracranial pressure in pediatric patients with craniosynostosis.

Methods:
Pediatric patients with craniosynostosis undergoing surgical intervention between 2014 and 2019 prospectively underwent optical coherence tomographic evaluation. Intracranial pressure was directly measured intraoperatively in a subset of cases. Optical coherence tomographic parameters were compared to directly measured intracranial pressure and used for pattern assessment.

Results:
Optical coherence tomography was performed in 158 subjects, among which 42 underwent direct intracranial pressure measurement during an initial cranial procedure. Maximal retinal nerve fiber layer thickness, maximal retinal thickness, and maximal anterior projection optical coherence tomographic parameters were positively correlated with intracranial pressure (p ≤ 0.001), with all parameters showing significantly higher values in patients with intracranial pressure thresholds of 15 mmHg (p < 0.001) and 20 mmHg (p ≤ 0.007). Patients with maximal retinal nerve fiber layer thickness and maximal anterior projection exceeding set thresholds in optical coherence tomography of either eye demonstrated 77.3 percent sensitivity and 95.0 percent specificity for detecting intracranial pressure above 15 mmHg, and 90.0 percent sensitivity and 81.3 percent specificity for detecting intracranial pressure above 20 mmHg. Patients with associated syndromes or multiple suture involvement and patients aged 9 months or older were significantly more likely to have elevated intracranial pressure above 15 mmHg (p ≤ 0.030) and above 20 mmHg (p ≤ 0.035).

Conclusions:
Spectral-domain optical coherence tomography can noninvasively detect elevated intracranial pressure in patients with craniosynostosis with reliable sensitivity and specificity. This technology may help guide decisions about the appropriate type and timing of surgical treatment.

The Influence of Topical Vasodilator-Induced Pharmacologic Delay on Cutaneous Flap Viability and Vascular Remodeling
Authors: Wu Zi Jun , Ibrahim Mohamed M. , Sergesketter Amanda R. , Schweller Ryan M. , Phillips Brett T. , Klitzman Bruce 
Published: January 2022

Background:
Surgical delay is a well-described technique to improve survival of random and pedicled cutaneous flaps. The aim of this study was to test the topical agents minoxidil and iloprost as agents of pharmacologic delay to induce vascular remodeling and decrease overall flap necrosis as an alternative to surgical delay.

Methods:
Seven groups were studied (n = 8 in each group), including the following: vehicle, iloprost, or minoxidil before treatment only; vehicle, iloprost, or minoxidil before and after treatment; and a standard surgical delay group as a positive control. Surgical flaps (caudally based modified McFarlane myocutaneous skin flaps) were elevated after 14 days of pretreatment, reinset isotopically, and observed at various time points until postoperative day 7. Gross viability, histology, Doppler blood flow, perfusion imaging, tissue oxygenation measurement, and vascular casting were performed for analysis.

Results:
Pharmacologic delay with preoperative application of topical minoxidil or iloprost was found to have comparable flap viability when compared to surgical delay. Significantly increased viability in all treatment groups was observed when compared with vehicle. Continued postoperative treatment with topical agents had no effect on flap viability. The mechanism of improved flap viability was inducible increases in flap blood volume and perfusion rather than the acute vasodilatory effects of the topical agents or decreased flap hypoxia.

Conclusions:
Preoperative topical application of the vasodilators minoxidil or iloprost improved flap viability comparably to surgical delay. Noninvasive pharmacologic delay may reduce postoperative complications without the need for an additional operation.

Clinical Relevance Statement:
Preoperative use of topical vasodilators may lead to improved flap viability without the need for a surgical delay procedure. This study may inform future clinical trials examining utility of preoperative topical vasodilators in flap surgery.
Pressure Injuries in Critical Care Patients in US Hospitals
Authors: Cox Jill , Edsberg Laura E. , Koloms Kimberly , VanGilder Catherine A. 
Published: January 2022

PURPOSE:
The purpose of this secondary analysis was to examine pressure injury (PI) prevalence, PI risk factors, and prevention practices among adult critically ill patients in critical care units in the United States using the International Pressure Ulcer Prevalence™ (IPUP) Survey database from 2018 to 2019.

DESIGN:
Observational, cohort study with cross-sectional data collection and retrospective data analysis.

SUBJECTS AND SETTING:
The sample comprised 41,866 critical care patients drawn from a sample of 296,014 patients in US acute care facilities who participated in the 2018 and/or 2019 IPUP surveys. The mean age among critical care patients was 63.5 years (16.3) and 55% were male. All geographic regions of the United States were represented in this sample, with the greatest percentages from the Southeast (47.5%) and Midwest (17.5%) regions.

METHODS:
Overall critical care PI prevalence and hospital-acquired PI (HAPI) rates were obtained and analyzed using the 2018/2019 IPUP survey database. Critical care PI risk factors included in the database were analyzed using frequency distributions. Prevention practices among critically ill patients were analyzed to evaluate differences in practices between patients with no PIs, superficial PIs (stage 1, stage 2), and severe PIs (stage 3, stage 4, unstageable, deep tissue pressure injury).

RESULTS:
The overall PI prevalence for critical care patients was 14.3% (n = 5995) and the overall HAPI prevalence was 5.85% (n = 2451). In patients with severe HAPIs, the most common risk factors were diabetes mellitus (29.5%), mechanical ventilation (27.6%), and vasopressor agents (18.9%). Significant differences between patients with no PIs as compared to those with superficial or severe HAPIs (P = .000) for all prevention practices were found.

CONCLUSIONS:
Study findings support the gaps elucidated in previous critical care studies on PI development in this population. The 2 most persistent gaps currently challenging critical care practitioners are (1) accurate risk quantification in this population and (2) the potential for unavoidability in PI development among critically ill patients.

ABSTRACTWild birds have great prominence on transmission of diseases to humans, mainly due to their ease of access to human population, raising concerns about the potential impact of that proximity in context of the One Health. Studies referring to circulation of avian reovirus (ARV) and picobirnavirus (PBV) in wild birds are limited, in addition to reinforcing the development of researches that describe the prevalence, characterize the variants and evaluate the potential impact of these infections on the wild ecosystem and public health. The present study reports the occurrence of ARV and PBV in wild birds collected from an environmental protection area in the Amazon biome. RT-PCR analysis showed ARV infection prevalence in 0.6% (1/155) and PBV infection in 1.29% (2/155) on the samples. ARV strain isolated in this study demonstrated more phylogenetically related to other ARVs previously circulating in poultry in the same region. The two PBV strains obtained belong to genogroup I, and showed phylogenetically related to other PBV isolated from different animal species in different geographic regions. This study is a pioneer in the detection of ARV in wild birds in Brazil and presents a report of the first occurrence of PBV in wild birds of Guira guira specie. Additional studies in wild birds are required to increase the epidemiology, origin, evolution and emergence of new viruses that may provoke problems in the context of One Health.
Immunokinetic Model for COVID-19 Patients

Published: January 2022

AbstractIn this paper, we develop a fractional-order differential model for the dynamics of immune responses to SARS-CoV-2 viral load in one host. In the model, a fractional-order derivative is incorporated to represent the effects of temporal long-run memory on immune cells and tissues for any age group of patients. The population of cytotoxic T-cells (CD8+), natural killer (NK) cells and infected viruses are unknown in this model. Some interesting sufficient conditions that ensure the asymptotic stability of the steady states are obtained.This model indicates some complex phenomena in COVID-19 such as “immune exhaustion” and “Long COVID”. Sensitivity analysis is also investigated for model parameters to determine the parameters that are effective in determining of the long COVID duration, disease control and future treatment as well as vaccine design. The model is verified with clinical and experimental data of 5 patients with COVID-19.
