of the other overweight/obese categories, in fact some had reduced odds of various adverse outcomes. CONCLUSIONS Underweight and super morbidly obese patients have the greatest odds of adverse outcomes after anterior cervical spine surgery. The current study identifies underweight patients as an at-risk population that has previously not received significant focus. Physicians and healthcare systems should give additional consideration to this population, as they often already do for those at the other end of the BMI spectrum. BACKGROUND CONTEXT Postoperative pyogenic spondylodiscitis is associated with prolonged antimicrobial therapy and high relapse rates. Cefuroxime is a time-dependent antimicrobial widely used for intravenous perioperative prophylaxis in spine surgery. A previous study has indicated that a single dose of cefuroxime (1.5 g) provides insufficient spine tissue concentrations for spine procedures lasting more than 2-3 hours. PURPOSE To evaluate the time with concentrations above relevant minimal inhibitory concentrations (T>MIC) in plasma, subcutaneous adipose tissue, vertebral cancellous bone, and intervertebral disc after a twofold increase of the standard dosage of 1.5 g cefuroxime given as one double dose (1 × 3 g) or two single doses (2 × 1.5 g) with a four-hour interval. METHOD Sixteen pigs were randomized into two groups Group 1 received one double dose of cefuroxime (1 × 3 g) as an intravenous bolus and Group 2 received two single doses of cefuroxime (2 × 1.5 g) as an intravenous bolus with a four-hour intedoses at a maximum interval of four hours for extended spine procedures. Clinical studies verifying these results are warranted. CLINICAL SIGNIFICANCE Administering cefuroxime as two single doses (2 × 1.5 g) with a four-hour interval compared with one double dose (1 × 3 g) resulted in higher T>MIC. Furthermore, we found delayed and incomplete cefuroxime tissue penetration. Sodium nitroprusside (SNP) is a nitric oxide (NO) donor which actually is under assessment as a potential candidate for the treatment of schizophrenia. It is well documented that anxiety symptoms are a prominent future in various psychiatric diseases comprising schizophrenia. Prior research has shown that acute challenge with SNP (1-3 mg/kg) induced anti-anxiety effects in rats but these effects at high doses were confounded by sedation and were disappeared after repeated application of it. It is still unknown if administration of a lower SNP dose range, either acutely or sub-chronically, could induce anxiolytic-like behaviour. The present study was designed to investigate this issue in rats. For this aim, the light/dark and the open field tests were used. Acute challenge with SNP (0.1 and 0.3 mg/kg, 30 min before testing) did not affect rodents' performance in the above mentioned behavioural paradigms. Conversely, rats treated sub-chronically with SNP (0.1 and 0.3 mg/kg, once per day, for 5 consecutive days), displayed longer time spent in the light chamber of the light/dark box and in the central area of the open field with respect to their vehicle-treated counterparts. Interestingly, SNP did not influence the first latency to enter the dark chamber and the number of transitions between the light and dark compartments of the apparatus in the light/dark test and did not modify the number of squares crossed, grooming episodes and rearings in the open field test. Finally, acute administration of SNP (0.1, 0.3 and 1 mg/kg, 10 min before testing) also did not influence rats' performance in the light/dark test. The present results indicate that short-term repeated but not acute application of a range of low doses of the NO donor SNP in a dose-independent manner induced an anti-anxiety behaviour in the rat which was not accompanied by undesired effects. Plants utilize nucleotide-binding (NB), leucine-rich repeat (LRR) receptors (NLRs) to detect pathogen effectors, leading to effector-triggered immunity. N6022 molecular weight The NLR ZAR1 indirectly recognizes the Xanthomonas campestris pv. campestris effector AvrAC and Pseudomonas syingae effector HopZ1a, by associating with closely related receptor-like cytoplasmic kinase subfamily XII-2 (RLCK XII-2) members RKS1 and ZED1, respectively. Recently, we showed that ZAR1, RKS1, and the AvrAC-modified decoy PBL2UMP form a pentameric resistosome in vitro, and the ability of resistosome formation is required for AvrAC-triggered cell death and disease resistance. However, it remains unknown whether the effectors induce ZAR1 oligomerization in the plant cell. Here, we show that both AvrAC and HopZ1a can induce oligomerization of ZAR1 in Arabidopsis protoplasts. Residues mediating ZAR1-ZED1 interaction are indispensable for HopZ1a-induced ZAR1 oligomerization in vivo and disease resistance. In addition, ZAR1 residues required for the assembly of ZAR1 resistosome in vitro are also essential for HopZ1a-induced ZAR1 oligomerization in vivo and disease resistance. Our study provides evidence that pathogen effectors induce ZAR1 resistosome formation in the plant cell and that the resistosome formation triggers disease resistance. Vitamin D plays a pivotal role in intestinal homeostasis. Vitamin D can impact the function of virtually every cell in the gut by binding to its intracellular receptor (VDR) and subsequently transcribing relevant genes. In the lumen, the mucus layer and the underlying epithelium serve to keep resident microbiota at bay. Vitamin D ensures an appropriate level of antimicrobial peptides in the mucus and maintains epithelial integrity by reinforcing intercellular junctions. Should bacteria penetrate the epithelial layer and enter the interstitium, immune sentinel cells (e.g. macrophages, dendritic cells, and innate lymphoid cells) elicit inflammation and trigger the adaptive immune response by activating Th1/Th17 cells. Vitamin D/VDR signaling in these cells ensures clearance of the bacteria. Subsequently, vitamin D also quiets the adaptive immune system by suppressing the Th1/Th17 cells and favoring Treg cells. The importance of vitamin D/VDR signaling in intestinal homeostasis is evidenced by the development of a chronic inflammatory state (e.g. IBD) when this signaling system is disrupted. OBJECTIVES Effective methods for diagnosing urogenital tuberculosis (UGTB) are important for its clinical management. Therefore, we undertook a systematic review to assess the performance of urine-based Xpert MTB/RIF assay for UGTB. METHODS PubMed, Embase, Web of Science, the Cochrane library, and Scopus were systematically searched up to July 30, 2019. A hierarchical summary receiver operating characteristic (HSROC) was applied to calculate the pooled sensitivity, specificity, positive likelihood ratio (PLR), negative likelihood ratio (NLR), and odds ratio (OR) for the diagnostic accuracy of the Xpert test. RESULTS Our search identified 858 unique articles from which 69 studies were selected for full-text revision, and 12 studies met inclusion criteria. Eleven studies comprising 1202 samples compared Xpert with mycobacterial culture while 924 samples from eight studies compared it with composite reference standard (CRS). The pooled sensitivity, specificity, PLR, NLR, and OR was 0.89, 0.95, 20.1, 0.18, and 159.53 compared to the mycobacterial culture, respectively. Likewise, when compared to CRS, the respective pooled sensitivity, specificity, PLR, NLR, and OR was 0.55, 0.99, 40.67, 0.43, and 166.17, thereby suggesting a high accuracy for diagnosing UGTB. A meta-regression and sub-group analysis of TB-burden countries, study design, decontamination, concentration, and reference standard could not explain the heterogeneity (p > 0.05) in the diagnostic efficiency. CONCLUSIONS Our results suggested that Xpert is a promising diagnostic tool for the diagnosis of UGTB via urine specimen. We report a familial cluster of 2019 novel coronavirus disease (COVID-19) to evidence that a potential transmission of the COVID-19 during the incubation period. The first patient in this familial cluster was identified in presymptomatic period, as a close contact of a confirmed patient. Five family members had close contact with the first patient during his incubation period, four of them were confirmed to the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection in the subsequent sampling test. INTRODUCTION Acute gastroenteritis caused by virus is a major public health concern especially among children younger than 5 years. This study seeks to determine the occurrence of human astrovirus infection in children infected with acute gastroenteritis. METHODS Stool specimens were collected from 506 children under five years hospitalized with acute diarrhoea (289 males and 208 females) and human astrovirus was investigated by RT-PCR. Associations of social, demographic, clinical and behavioural conditions with infection were analysed. RESULTS The overall prevalence of 10.3% of human astrovirus was detected. The mean age of positive cases was (12.41 ± 6.21) months and was associated with infection (p = 0.013). Children of age 18 months and above were 3 times at risk of infection (OR = 3.19; CI = 1.15-8.88 p = 0.026).Children living in houses with more than one room and mothers using treated water were associated with reduced infection (OR = 0.60CI = 0.28-0.96p = 0.036 and OR = 0.47 CI = 0.25-0.86p = 0.015) respectfully. CONCLUSION In this study, infection with astrovirus was common in acute gastroenteritis cases among children younger than 5 years. Drinking treated water and living in non-crowded environments protect from infection. Biallelic variants in BLNK cause primary B-cell immunodeficiency that usually results in absence of B cells and immunoglobulin. Here, we identified disease-causing variant(s) in two unrelated Chinese patients with agammaglobulinemia. Patient 1 showed a moderate reduction in total B-cell count but demonstrated both extremely low levels of memory B-cells and lower levels of memory T cells relative to those in healthy controls. Whole-exome sequencing (WES) revealed a novel heterozygous splice variant (c.676+1G>A), and suggested exon 9 deletion from BLNK, which was subsequently validated by quantitative polymerase chain reaction. For Patient 2, WES revealed novel compound heterozygous of a frameshift variant (p.T152Pfs*6) and a synonymous variant (c.525G>A) that resulted in exon 6 skipping, according to cDNA sequencing. These findings represent the first report of a BLNK-deficient patient presenting with impaired memory B-cell and memory T-cell development. Furthermore, this study is the first reporting a pathogenic synonymous splice variant in BLNK. Increased pro-inflammatory cytokines and an overactive hypothalamic-pituitary-adrenal (HPA) axis have both been implicated in the pathogenesis of depression. However, these explanations appear contradictory because glucocorticoids are well recognised for their anti-inflammatory effects. Two hypotheses exist to resolve this paradox the mediating presence of glucocorticoid receptor resistance, or the possibility that glucocorticoids can potentiate inflammatory processes in some circumstances. We sought to investigate these hypotheses in a cell model with significant relevance to depression human hippocampal progenitor cells. We demonstrated that dexamethasone in vitro given for 24 hours and followed by a 24 hours rest interval before an immune challenge potentiates inflammatory effects in these neural cells, that is, increases the IL-6 protein secretion induced by stimulation with IL-1β (10 ng/mL for 24 hours) by + 49% (P less then 0.05) at a concentration of 100 nM and by + 70% (P less then 0.01) for 1 μM.
