Acute lung injury induced by intestinal ischemia/reperfusion (I/R) is a relevant clinical condition. Acetylcholine (ACh) and the α7 nicotinic ACh receptor (nAChRα-7) are involved in the control of inflammation. Mice with reduced levels of the vesicular ACh transporter (VAChT), a protein responsible for controlling ACh release, were used to test the involvement of cholinergic signaling in lung inflammation due to intestinal I/R. Female mice with reduced levels of VAChT (VAChT-KDHOM) or wild-type littermate controls (WT) were submitted to intestinal I/R followed by 2 h of reperfusion. Mortality, vascular permeability, and recruitment of inflammatory cells into the lung were investigated. Parts of mice were submitted to ovariectomy (OVx) to study the effect of sex hormones or treated with PNU-282,987 (nAChRα-7 agonist). A total of 43.4% of VAChT-KDHOM-I/R mice died in the reperfusion period compared to 5.2% of WT I/R mice. The I/R increased lung inflammation in both genotypes. In VAChT-KDHOM mice, I/R increased vascular permeability and decreased the release of cytokines in the lung compared to WT I/R mice. Ovariectomy reduced lung inflammation and permeability compared to non-OVx, but it did not avoid mortality in VAChT-KDHOM-I/R mice. PNU treatment reduced lung permeability, increased the release of proinflammatory cytokines and the myeloperoxidase activity in the lungs, and prevented the increased mortality observed in VAChT-KDHOM mice. Cholinergic signaling is an important component of the lung protector response against intestinal I/R injury. Decreased cholinergic signaling seems to increase pulmonary edema and dysfunctional cytokine release that increased mortality, which can be prevented by increasing activation of nAChRα-7.There is conflicting evidence regarding the significance of iatrogenic atrial septal defects (iASDs) after transseptal puncture during percutaneous cardiac interventions. To study the clinical outcome of iASD after percutaneous left atrial appendage occlusion (LAAo). Single-center, retrospective study of 70 consecutive patients who underwent percutaneous LAAo between May 2010 and August 2017, and subsequent transesophageal echocardiography (TEE) at 1 month. The sample population was divided into two groups A (with iASD, 22 (37%) patients) and B (no iASD, 44 (63%) patients). Procedures were guided either by TEE (36 patients (54%)) or intracardiac echocardiography (ICE) from the left atrium (30 patients (46%)). The primary end point was presence of iASD at 1 month, and secondary end points included mortality, hospital admission due to heart failure (HF), and right atrium (RA) size during follow-up. 70 patients were included in this study and the prevalence of iASD at 1 month was 37%. The use of ICE was associated with iASD (adjusted odds ratio, 3.79; 95% CI 1.27-11.34). The presence of iASD was not associated with adverse events (mortality, 15.4% vs 20.5%; P = 0.60; HF hospitalizations, 7.7% vs 13.6%, P = 0.45; and RA area, 24.8 ± 7.0 cm2 vs 22.2 ± 6.8 cm2, P = 0.192). At 1-month follow-up after LAAo, iASD was present in one third of patients, but was not associated with clinical outcomes. The use of ICE was associated with a higher risk of short-term iASD.Left ventricular remodeling (LVR) after ST-elevation myocardial infarction (STEMI) is generally thought to be an adaptive but compromising phenomenon particularly in patients with diabetes mellitus (DM). However, whether the extent of LVR is associated with poor prognostic outcome with or without DM after STEMI in the modern era of reperfusion therapy has not been elucidated. This was a single-center retrospective observational study. Altogether, 243 patients who were diagnosed as having STEMI between January 2016 and March 2019, and examined with echocardiography at baseline (at the time of index admission) and mid-term (from 6 to 11 months after index admission) follow-up were included and divided into the DM (n = 98) and non-DM groups (n = 145). The primary outcome was major adverse cardiovascular events (MACEs) defined as the composite of all-cause death, heart failure (HF) hospitalization, and non-fatal myocardial infarction. The median follow-up duration was 621 days (interquartile range 304-963 days). The DM group was significantly increased the rate of MACEs (P = 0.020) and HF hospitalization (P = 0.037) compared with the non-DM group, despite of less LVR. Multivariate Cox regression analyses revealed that the patients with DM after STEMI were significantly associated with MACEs (Hazard ratio [HR] 2.79, 95% confidence interval [CI] 1.20-6.47, P = 0.017) and HF hospitalization (HR 3.62, 95% CI 1.19-11.02, P = 0.023) after controlling known clinical risk factors. LVR were also significantly associated with MACEs (HR 2.44, 95% CI 1.03-5.78, P = 0.044) and HF hospitalization (HR 3.76, 95% CI 1.15-12.32, P = 0.029). The patients with both DM and LVR had worse clinical outcomes including MACEs and HF hospitalization, suggesting that it is particularly critical to minimize LVR after STEMI in patients with DM.There are regular reports of extrapulmonary infections and manifestations related to the ongoing COVID-19 pandemic. Coronaviruses are potentially neurotropic, which renders neuronal tissue vulnerable to infection, especially in elderly individuals or in those with neuro-comorbid conditions. Complaints of ageusia, anosmia, myalgia, and headache; reports of diseases such as stroke, encephalopathy, seizure, and encephalitis; and loss of consciousness in patients with COVID-19 confirm the neuropathophysiological aspect of this disease. The brain is linked to pulmonary organs, physiologically through blood circulation, and functionally through the nervous system. The interdependence of these vital organs may further aggravate the pathophysiological aspects of COVID-19. The induction of a cytokine storm in systemic circulation can trigger a neuroinflammatory cascade, which can subsequently compromise the blood-brain barrier and activate microglia- and astrocyte-borne Toll-like receptors, thereby leading to neuronal tissue damage. Hence, a holistic approach should be adopted by healthcare professionals while treating COVID-19 patients with a history of neurodegenerative disorders, neuropsychological complications, or any other neuro-compromised conditions. Imperatively, vaccines are being developed at top priority to contain the spread of the severe acute respiratory syndrome coronavirus 2, and different vaccines are at different stages of development globally. This review discusses the concerns regarding the neuronal complications of COVID-19 and the possible mechanisms of amelioration.Hypophosphatemia is a rare side effect of intravenous iron replacement. Urinary phosphate wasting due to increased FGF23 is the most likely mechanism. Here, we present a case of intractable hypophosphatemia in a 32-year-old female patient with history of ulcerative colitis (UC), who was primarily hospitalized due to UC flare-up. Her urinary fractional excretion of phosphate was inappropriately elevated at 70%. A careful history revealed that she had been treated with ferric carboxymaltose 2 weeks prior to hospitalization, leading to a diagnosis of iron-induced hypophosphatemia. She was treated with 5 weeks of intravenous sodium phosphate since she did not tolerate oral supplementation. In conclusion, clinicians should be aware of iron-induced hypophosphatemia and be cautious when prescribing intravenous iron.Two Gram-stain positive, endospore forming, non-motile, rod shaped bacterial strains SN6T and SN6b were isolated from scats of a mildly venomous vine snake (Ahaetulla nasuta). Strains were phenotypically resistant to multiple antibiotics of four different classes i.e. aminoglycosides, β-lactams, fluoroquinolones and sulphonamides. [https://www.selleckchem.com/products/Teniposide(Vumon).html Teniposide mouse] Cells of both the strains were catalase positive and oxidase negative. Phylogenetic analysis based on 16S rRNA gene sequence analysis of these two strains showed closest similarity (99.2% and 99.3%) with Savagea faecisuis Con12T, the only species of the genus Savagea and ≤ 94.9% with the species of other closest genera of the family Planococcaceae. The 16S rRNA gene sequence similarity (99%), DNA-DNA relatedness (95%) and similar phenotypic characteristics between the strains SN6T and SN6b revealed their phylogenetic affiliation to the same species. Hence, strain SN6b is an additional strain of the type strain SN6T. DNA-DNA relatedness of strain SN6T with S. faecisuis Con12T was 32.8%. Predominant fatty acids were iso-C150 (32.0%), iso-C161 ω11c (19.2%) and iso-C171 ω10c (12.1%). MK-6 (100%) was the only respiratory quinone of strain SN6T. Diphosphatidylglycerol, phosphatidylglycerol and phosphatidylethanolamine were the major polar lipids. Cell wall peptidoglycan was A4α; L-Lys-Gly-D-Glu type. The DNA G + C content (mol%) of SN6T was 40.8. Whole genome sequence of SN6T consisted of 26,37,389 base pairs in length with 2667 annotated genes, out of which 1021 corresponds to hypothetical proteins and 1646 with functional assignments including antibiotic resistance, multidrug resistance efflux pumps, invasion and virulence factors. Comparative polyphasic study of the strains SN6T, SN6b and S. faecisuis Con12T elucidated the differentiating characteristics which led to describing strain SN6T and SN6b as a novel species of the genus Savagea for which the name Savagea serpentis sp. nov is proposed. The type strain of Savagea serpentis is SN6T (= KCTC 33546T = CCUG 6786T).Strains belonging to the Pseudomonas genus have been isolated worldwide from various biotic (humans, animals and plant tissues) and abiotic (food, soil, water and air) environments. Raw milk provides a favorable environment for the growth of a broad spectrum of microorganisms, including Pseudomonas. Here we present the description of Pseudomonas sp. UCMA 17988 isolated from raw milk, which was previously reported to produce new antimicrobial lipopeptides. MultiLocus Sequence Analysis of four housekeeping genes (16S rRNA, gyrB, rpoD and rpoB), whole genome sequence comparison (orthoANI value, original ANI value and dDDH value), microscopy, FAME analysis, and biochemical tests were performed. Digital DNA-DNA hybridization and average nucleotide identity values between strain UCMA 17988 and its closest relatives, P. helmanticensis CECT 8548T (46.9%, 92.07%) and P. baetica CECT 7720T (26.8%, 88.50%), rate well below the designed threshold for assigning prokaryotic strains to the same species. In conclusion, strain UCMA 17988 belongs to a novel species, for which the name Pseudomonas crudilactis sp. nov (type strain UCMA 17988T = DSM 109949T = LMG 31804T) is proposed.<br /><br /> Vitamin D-dependent rickets type 1b (VDDR1b) is a very rare autosomal recessive disorder caused by mutations in CYP2R1 that produces 25-hydroxylase. To date only five mutations in CYP2R1 have been identified. This study has reported the genetic results and the clinical characteristics of a family with VDDR1b and compared this family to the other families with VDDR1b in literature.<br /><br /> After two probands were diagnosed with VDDR1b, all other family members were evaluated. Serum calcium, phosphorus, alkaline phosphatase, parathyroid hormone, 25-hydroxy vitamin D, and 1.25-dihydroxy vitamin D levels were measured in all family members. All individuals were evaluated radiographically, and a genetic analysis was done in all family members. The other families with VDDR1b in literature were reviewed.<br /><br /> Two novel mutations [c.367 + 1G &gt; C and p.E339Q (c.1015G &gt; C)] were identified. The clinic and laboratory findings were strikingly different among the members of this family regardless of the mutation and the number of alleles affected.
