A Systematic Review of Donor Serum Sodium Level and Its Impact on Transplant Recipients

Background: An important aspect of donor management is the optimization of serum sodium levels. Objective: To perform a systematic review to determine the effects of donor sodium levels on heart, lung, kidney, and pancreas graft function, recipient mortality, and to identify the optimal donor serum sodium target. Methods: We searched MEDLINE, Cochrane, Guideline databases, and trial registries from 1946 to May 2019 for studies investigating the effects of donor serum sodium levels on transplant outcomes in all non-hepatic organs. A two-step independent review process was used to identify relevant articles based on inclusion/exclusion criteria. We describe the results narratively, assess the risk of bias, and apply GRADE methodology to evaluate the certainty in the evidence. Results: We included 18 cohort studies in our final analysis (n=28,007). 3 of 4 studies demonstrated an association between donor serum sodium and successful organ transplantation. 5 studies reported no association with graft function, while 6 studies did. 5 studies reported on recipient survival, 3 of which suggested donor sodium is unlikely to be associated with recipient survival. The included studies had serious risk of bias, and the certainty in evidence was deemed to be very low. Conclusion: In low risk of bias studies, donor sodium dysregulation is unlikely to affect kidney graft function or mortality of heart and kidney recipients, but the certainty in the evidence is very low due to inconsistency and imprecision. Further research is required to refine the serum sodium target range, quantify the dose-response curve, and identify organs most vulnerable to sodium dysregulation.
Investigating the GWAS-Implicated Loci for Rheumatoid Arthritis in the Pakistani Population

Rheumatoid arthritis (RA) is a complex and multifactorial autoimmune disorder with the involvement of multiple genetic and environmental factors. Genome-wide association studies (GWAS) have identified more than 50 RA genetic loci in European populations. Given the anticipated overlap of RA-relevant genes and pathways across different ethnic groups, we sought to replicate 58 GWAS-implicated SNPs reported in Europeans in Pakistani subjects. 1,959 unrelated subjects comprising 1,222 RA cases and 737 controls were collected from three rheumatology facilities in Pakistan. Genotyping was performed using iPLEX or TaqMan® methods. A total of 50 SNPs were included in the final association analysis after excluding those that failed assay design/run or postrun QC analysis. Fourteen SNPs (LINC00824/rs1516971, PADI4/rs2240336, CEP57/rs4409785, CTLA4/rs3087243, STAT4/rs13426947, HLA-B/MICA/rs2596565, C5orf30/rs26232, CCL21/rs951005, GATA3/rs2275806, VPS37C/rs595158, HLA-DRB1/rs660895, EOMES/rs3806624, SPRED2/rs934734, and RUNX1/rs9979383) were replicated in our Pakistani sample at false discovery rate (FDR) of <0.20 with nominal p values ranging from 4.73E-06 to 3.48E-02. Our results indicate that several RA susceptibility loci are shared between Pakistani and European populations, supporting the role of common genes/pathways.
Protection of Fecal Microbiota Transplantation in a Mouse Model of Multiple Sclerosis

Given the growing evidence of a link between gut microbiota (GM) dysbiosis and multiple sclerosis (MS), fecal microbiota transplantation (FMT), aimed at rebuilding GM, has been proposed as a new therapeutic approach to MS treatment. To evaluate the viability of FMT for MS treatment and its impact on MS pathology, we tested FMT in mice with experimental autoimmune encephalomyelitis (EAE), a mouse model of MS. We provide evidence that FMT can rectify altered GM to some extent with a therapeutic effect on EAE. We also found that FMT led to reduced activation of microglia and astrocytes and conferred protection on the blood-brain barrier (BBB), myelin, and axons in EAE. Taken together, our data suggest that FMT, as a GM-based therapy, has the potential to be an effective treatment for MS.
Effect of Foot Reflexology on Pain, Fatigue, and Quality of Sleep after Kidney Transplantation Surgery: A Parallel Randomized Controlled Trial

Materials and Methods The study was a parallel randomized controlled trial. Patients admitted to the transplantation ward participated in the study. Fifty-three eligible patients were allocated into the foot reflexology group (n = 26) and the control group (n = 27) by using the stratified randomization method. Finally, 25 participants in each group finished the study. The intervention group received foot reflexology for 30 minutes once a day for three consecutive days, and no reflexology was applied in the control group. The intervention started on the second day after surgery. Pain, fatigue, and quality of sleep were measured on the first, second (before intervention), third, fourth, and eleventh days after surgery. Data were collected using visual analogue scale for measuring pain and fatigue and Verran and Snyder-Halpern sleep scale for measuring quality of sleep. Results In each group, 25 patients finished the study. The mean pain score in the foot reflexology and control groups decreased from 9.44 ± 0.96 and 9.36 ± 0.91 on the day of surgery to 1.32 ± 0.94 and 4.32 ± 1.68 on the eleventh day after surgery, respectively. The mean fatigue score in the reflexology and control groups decreased from 8.76 ± 1.27 and 8.6 ± 1.26 on the day of surgery to 1.24 ± 1.2 and 3.92 ± 1.63 on the eleventh day after surgery, respectively. The mean sleep score in the foot reflexology and control groups increased from 33.38 ± 11.22 and 39.59 ± 12.8 on the day of surgery to 69.43 ± 12.8 and 56.27 ± 8.03 on the eleventh day after surgery, respectively. While pain, fatigue, and sleep quality scores improved in both groups, those in the intervention group showed significantly greater improvement compared with the control group (P < 0.001). No significant difference was found between the two groups in the use of acetaminophen on the first, second, third, fourth, and eleventh days after surgery (P > 0.05). Conclusion Foot reflexology may reduce pain and fatigue and improve sleep quality of patients after kidney transplantation.
Traditional rural values and posttraumatic stress among rural and urban undergraduates

Although rurality is often treated as an aspect of diversity, researchers disagree regarding whether the traditional rural values of self-reliance, distrust of outsiders, religiosity, centrality of family, and fatalism continue to differentiate rural versus urban undergraduates. The present study examined 1) whether differences in these values exist between rural and urban college students in the United States and 2) whether these rural values might mediate the association between geographic remoteness and posttraumatic stress symptom (PTSS) severity. College undergraduates in the United States who reported experiencing traumatic and/or stressful events (N = 213) completed measures of these constructs through an online survey. T-test results indicated that rural respondents had significantly higher levels of PTSS severity and distrust of outsiders and significantly lower levels of religiosity when compared with urban participants. After controlling for gender, distrust of outsiders and religiosity also emerged as significant mediators of the relationship between geographic remoteness and PTSS severity. Thus, despite research that highlights differences based on geographic location, similarities and differences exist for rural and urban undergraduates in the United States with regard to traditionally rural values. For rural undergraduate clients presenting with trauma symptoms, our results suggest that building trust and religious and/or spiritual self-care may be particularly critical.
The Variation of Peripheral Inflammatory Markers in Vocal Leukoplakia before and after Recurrence and Canceration

Background This retrospective study aims at comparing the variation of peripheral inflammatory markers in recurrent and cancerous vocal fold leukoplakia (VFL) and at exploring the potential connection with pathological outcomes. Methods The patients undergoing carbon dioxide laser surgery with postoperative pathological diagnosis of recurrent vocal fold leukoplakia in the last 5 years were included. The clinical data were collected, and neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), and monocytes-to-lymphocyte ratio (MLR) before and after recurrence and canceration were calculated. Related comparison with two-grade pathological classification was made to evaluate their potential connection with postsurgical histopathology and clinical events. Results The data of 193 patients were engaged into research, as 111 in the recurrence group (Group A) and 82 in canceration group (Group B). The NLR, PLR, and MLR were significantly increased in canceration event compared to the first (P = 0.009, 0.004, 0.007, respectively) and penultimate (P = 0.013, 0.041, 0.006, respectively) time when the previous pathologies were leukoplakia. When redividing the Group A according to the two-grade pathological classification, the high-risk groups showed statistically higher NLR and PLR values than low-risk groups in the subgroups with grade changing (P = 0.016, 0.005, 0.007, 0.005, respectively) and subgroups without grade changing (P = 0.020, 0.027, 0.030, 0.029, respectively). Conclusions NLR, PLR, and MLR are reliable biomarkers in the circulation system which show significantly interrelation with the pathological progression of vocal fold leukoplakia. Presurgical evaluation of NLR, PLR, and MLR may have potential values to indicate the following treatment in clinical practice.
Sex-biased dispersal and kin aggregation on leks in the black grouse (Tetrao tetrix)

Dispersal is an important factor shaping the genetic structure of populations and frequently in the animals, dispersal is biased by sex. The philopatric sex, for instance, might have a lot to gain from staying close to its birth place. One reason for this could be cooperative behaviour (inclusive fitness), which is only possible in aggregations of kin. In some lekking bird species, possibility of kin selection having an effect on the evolution of leks, has been proposed. It would explain why low ranking males participate lekking aggregations, when their prospects of having any matings are low. Displaying together with a dominant related males, low ranking males would lure more females to the lek by increasing the size of the lek. This may benefit low ranking males indirectly as females prefer larger leks. This has proved out to be a controversial hypothesis, some species having supporting evidence for it and some not. In this thesis we used 13 microsatellite loci to find out whether black grouse females disperse more than males and whether black grouse males aggregate according to kin more than expected as an effect of males' philopatric behaviour. In an analysis of molecular variance (AMOVA) males had a stronger pattern of structuring than females did. This indicates that males are more philopatric in the black grouse. For males being philopatric might be beneficial in acquiring a territory from a lek. Females might benefit from dispersing by getting a possibility to compare males in different areas and by avoiding inbreeding. In a test using pairwise relatedness estimates calculated for each lek, five out of twelve leks differed significantly from the null expectation of zero. However, when testing these relatedness values against the relatedness calculated between lekking and non-lekking individuals, there were no differences. Thus, even though some degree of relatedness is apparent between males on a same lek, it is still uncertain whether black grouse males actively choose leks occupied by their relatives. The observed level of relatedness between males on leks could be explained by their philopatric behaviour. Moreover, to test the importance of kin selection having an effect on black grouse lek formation, the costs and benefits of aggregation need to be assessed. For males to successfully find leks with relatives they should have a mechanism to recognize kin. A mechanism to recognize related individuals that have not been raised in the same nest has not been found in birds. Since no consensus on the importance of kin selection on the evolution of lek aggregation has been reached, other explanations have to be considered. Also, the importance of kin selection may vary between the species.
A Case Report of Coronavirus Disease 2019 Presenting with Tremors and Gait Disturbance

Introduction Neurologic symptoms present as significant complications of coronavirus disease 2019 (COVID-19) infection. This report describes a novel manifestation of tremors triggered by severe acute respiratory syndrome coronavirus 2 infection. Case Presentation We describe a case of a 46-year-old man with COVID-19 infection complicated by a bilateral intention tremor and wide-based gait. Although neurological manifestations have been reported related to COVID-19, tremulousness has not yet been described. Conclusion Considering the evolving diversity of neurologic manifestations in this infection, emergency physicians should be vigilant of possible COVID-19 infection in patients presenting with unexplained neurologic symptoms.
Direct Targeting of CREB1 with Imperatorin Inhibits TGFβ2‐ERK Signaling to Suppress Esophageal Cancer Metastasis

Metastasis accounts for 90% of cancer death worldwide, and effective therapeutic strategies are lacking. The aim of this work is to identify the key drivers in tumor metastasis and screen therapeutics for treatment of esophageal squamous cell carcinoma (ESCC). Gene Ontology analysis of The Cancer Genome Atlas (TCGA) gene expression datasets of ESCC patients with or without lympy metastasis identifies that TGFβ2 is highly enriched in the pathways essential for tumor metastasis and upregulates in the metastatic ESCC tumors. High TGFβ2 expression in ESCC correlates with metastasis and patient survival, and functionally contributes to tumor metastasis via activating extracellular signal‐regulated kinases (ERK) signaling. By screening of a library consisting of 429 bioactive compounds, imperatorin is verified as a novel TGFβ2 inhibitor, with robustly suppressive effect on tumor metastasis in multiple mice models. Mechanistically, direct binding of imperatorin and CREB1 inhibits phosphorylation, nuclear translocation of CREB1, and its interaction with TGFβ2 promoter, represses TGFβ2 expression and fibroblasts‐secreted CCL2, and then inactivates ERK signaling to block cancer invasion and abrogates the paracrine effects of fibroblasts on tumor angiogenesis and metastasis. Overall, the findings suggest the use of TGFβ2 as a diagnostic and prognostic biomarker and therapeutic target in ESCC, and supports the potential of imperatorin as a novel therapeutic strategy for cancer metastasis.
Diurnal and dietary impacts on estimating microbial protein flow from urinary purine derivative excretion in beef cattle1

Abstract Two experiments were conducted to determine the effects of diet composition and time of urine spot sampling on estimates of urinary purine derivative (PD) excretion. In Exp. 1, 116 individually fed crossbred heifers (407 ± 32 kg) were arranged in a randomized block design (82 d). Treatments were arranged in a 2 × 3 factorial design, with two urine spot sample collection times (0700 and 1700 hours; AM and PM) and three diets: 85% steam-flaked corn (SFC); 85% SFC + 1.5% urea (UREA); or 25% SFC, 30% wet corn gluten feed, and 30% corn bran (BYPROD). In Exp. 2, six ruminally and duodenally fistulated steers (474 ± 37 kg) were arranged in a replicated 3 × 3 Latin square design, with dietary treatments identical to Exp. 1 (63 d). Treatment diets were selected to result in varied amounts of microbial crude protein (MCP) in order to evaluate the accuracy of using estimates of urinary PD excretion to predict MCP. Urine spot samples were collected at 0700, 1200, 1700, and 2200 hours. No urine collection time × diet interactions occurred (P > 0.20) for any variable in either experiment. In Exp. 1, dry matter intake (DMI) was greatest with BYRPOD (10.40 kg/d) and lowest with SFC (7.90 kg/d; P < 0.05). Feed efficiencies were greatest for UREA (0.182) and least for SFC (0.141; P < 0.05). Urinary PD:creatinine (PD:C) ratio was greatest for BYPROD (1.25) and least for SFC (0.94; P < 0.05). Urine spot sampling time had a significant (P < 0.05) impact on PD:C, 1.03 for AM and 1.22 for PM samples. In Exp. 2, DMI was greater (P < 0.05) with BYPROD than with SFC and tended (P = 0.07) to be greater with BYPROD than with UREA. Ruminal pH was greatest for BYPROD (5.94; P < 0.05). Flow of MCP was 636, 829, and 1,056 g/d for SFC, UREA, and BYPROD, with BYPROD being greater (P < 0.05) than SFC and tending (P = 0.06) to be greater than UREA. Urinary PD:C was greater (P < 0.05) for BYPROD than SFC and tended (P = 0.09) to be greater for UREA than SFC. Urinary PD:C increased linearly (P < 0.05) with sampling time. Diets formulated to affect DMI and MCP flow resulted in differences in urinary PD excretion, and these results related well with MCP flow estimated from duodenal purines. Collecting spot samples of urine later in the day resulted in greater estimates of urinary PD excretion; purine and PD flows appear to increase with time after one morning feeding per day. This method is well suited to evaluating relative differences between treatments but should not be extrapolated to assume absolute values.
Mycotoxins Detection and Fungal Contamination in Black and Green Tea by HPLC-Based Method

The fungal contamination and total aflatoxins (AF) and ochratoxin A (OTA) of tea samples were examined. A total of 60 tea samples were extracted and treated with immunoaffinity columns. The amount of AF and OTA were determined by using high-performance liquid chromatography (HPLC) with a fluorescence detector (FD). Tea samples were cultured and the fungi were identified. The results showed that 24 (40%) samples were contaminated with AFs and none of the tea samples were above the acceptable limit of AFs (≥10 μg/kg). All of the samples were contaminated with OTA where only 3 black tea samples (6.6%) and 1 green tea sample (6.7%) were detected to have more than the standard limits of toxin (10 μg·kg−1). The mean concentration of OTA in the black tea was higher than green tea. Aspergillus niger was the predominant fungi isolated from black and green tea samples. Considering the high contamination of mycotoxins in tea samples, regular monitoring in the tea process for improving quality is recommended.
Peripheral Spexin Inhibited Food Intake in Mice

Spexin (SPX, NPQ), a novel endogenous neuropeptide, was firstly identified by bioinformatics. Spexin gene and protein widely distributed in the central nervous system and peripheral tissues, such as the hypothalamus and digestive tract. The role of spexin in appetite regulation in mammalian is still unclear. The present study was designed to investigate the mechanism and effect of peripheral spexin on food intake in mice. During the light period, an intraperitoneal (i.p.) injection of spexin (10 nmol/mouse) significantly inhibited cumulative food intake at 2, 4, and 6 h after treatment in fasted mice. During the dark period, spexin (1 and 10 nmol/mouse, i.p.) significantly suppressed cumulative food intake at 4 and 6 h after treatment in freely feeding mice. The GALR3 antagonist SNAP37889, not GALR2 antagonist, significantly antagonized the inhibitory effect on cumulative food intake (0–6 h) induced by spexin. Spexin significantly reduced the mRNA level of Npy mRNA, not Agrp, Pomc, Cart, Crh, Orexin, or Mch, in the hypothalamus. Spexin (10 nmol/mouse, i.p.) increased the number of c-Fos positive neurons in hypothalamic AHA and SCN, but not in ARC, DMN, LHA, PVN, SON, or VMH. The hypothalamic p-CaMK2 protein expression was upregulated by spexin. This study indicated that acute peripheral injection of spexin inhibited mouse food intake. The anorectic effect may be mediated by GALR3, and inhibiting neuropeptide Y (NPY) via p-CaMK2 and c-Fos in the hypothalamus.
Higher Serum Neuropeptide Y Levels Are Associated with Metabolically Unhealthy Obesity in Obese Chinese Adults: A Cross-Sectional Study

Objective Neuropeptide Y (NPY), an orexigenic peptide known to cause hyperphagia, has been involved in the occurrence and development of obesity. However, differences in the distribution of serum NPY levels in obese phenotypes (including metabolically unhealthy obesity (MUO) phenotype and metabolically healthy obesity (MHO) phenotype) and the association of NPY with MUO phenotype have not been unequivocally established. We therefore determined associations of serum NPY levels with MUO phenotype in obese Chinese adults. Methods A cross-sectional study was conducted from 400 obese adults in Hunan province, who underwent a health examination in the Second Xiangya Hospital, and 164 participants were finally enrolled in the study and divided into MHO and MUO groups. Serum NPY levels were examined; univariate and multivariate analyses as well as smooth curve fitting analyses were conducted to measure the association of NPY serum levels with the MUO phenotype. Results Serum NPY levels were significantly elevated in the MUO group compared with the MHO group ((667.69 ± 292.90) pg/mL vs. (478.89 ± 145.53) pg/mL, p < 0.001). A threshold and nonlinear association between serum NPY levels and MUO was found (p = 0.001). When serum NPY levels exceeded the turning point (471.5 pg/mL), each 10 pg/mL increment in the NPY serum level was significantly associated with an 18% increased odds ratio of MUO phenotype (OR: 1.18, 95% CI: 1.07–1.29, p = 0.0007) after adjusted for confounders. Conclusions Higher NPY serum levels were positively correlated with MUO phenotype in obese Chinese adults.
Does Luteal Phase Support Effect Pregnancy Rates in Intrauterine Insemination Cycles? A Prospective Randomised Controlled Study in a Tertiary Center

Intrauterine insemination (IUI) is a common treatment for couples with subfertility. Clomiphene citrate, gonadotropins, and letrozole are used for ovulation induction in IUI cycles. It has been well documented that luteal support with exogenous progesterone after in vitro fertilization is associated with higher pregnancy and live birth rates. Yet, luteal phase support in IUI cycles has become a debatable issue. The aim of this prospective controlled study was to assess the effect of luteal phase vaginal progesterone supplementation on β-hCG positivity and clinical pregnancy rates in women undergoing IUI. This prospective controlled randomised study was conducted at a tertiary infertility center. 87 patients with unexplained infertility or male subfertility who were treated with IUI using gonadotropins were enrolled. Patients in the study group (n = 44) received luteal phase vaginal progesterone supplementation. Patients in the control group (n = 43) did not receive any luteal phase support. There was no statistical difference between two groups in terms of β-hCG positivity and clinical pregnancy rates. Our findings do not show any beneficial effect of luteal phase support in IUI cycles stimulated with gonadotropins. Although luteal phase support in IUI cycles stimulated with gonadotropins is widely adopted, there is a lack of robust evidence.
