Arteriosclerosis, coronary artery disease, arteriolosclerosis, along with Monckeberg medial calcific sclerosis: is there a big difference?
Partial correlation coefficients showed that salt intake was a factor of the correlation between NUV and change in extracellular volume in the legs between 500 pm and 600 am. A multivariate logistic model showed that sleep duration and sodium clearance were independent predictive factors for nocturnal polyuria. Conclusions Sodium intake correlates with diurnal leg edema and NUV in elderly men. These results provide evidence supporting sodium restriction as an effective treatment for nocturnal polyuria.In this study, a simplified, sensitive and reliable LC-tandem mass spectrometry method was established and validated for the quantification of ulipristal acetate (UPA) in human plasma and for the investigation of pharmacokinetic profile of UPA following a single oral administration of ella (UPA 30-mg tablet) in healthy Chinese volunteers. Plasma samples were analyzed after being processed by protein precipitation with methanol. Chromatographic separation was performed on a Kinetex EVO C18 column (2.1 × 50 mm, 2.6 μm) using gradient elution with a mobile phase composed of methanol and water containing 2 mm ammonium acetate and 0.3% formic acid at a flow rate of 0.3 mL/min. The chromatographic running time was 4.0 min per sample. The MS detection was performed via an LC system with the positive ion electrospray ionization interface in multiple reaction monitoring mode using the transition of m/z 476.2 → 134.1 for UPA and m/z 479.3 → 416.2 for UPA-d3 [internal standard (IS)], respectively. UPA and IS were monitored without severe interference from the biological matrices. The method was linear over the wide concentration range of 0.300-300 ng/mL. The intra- and inter-day precision and accuracy were well within the limits required for bioanalytical assays. The method was first used to describe the pharmacokinetic characteristic of UPA after a single oral administration of ella in healthy Chinese volunteers. Based on a between-study comparison, there were statistically significant differences (p less then .05) between Chinese and Caucasian volunteers for the systemic exposure of UPA, suggesting that race seems to significantly impact the systemic exposure of UPA.Background Photobiomodulation (PBM) has proven to be effective in different painful conditions. Objectives To assess the effect of photobiomodulation for pain management in burning mouth syndrome (BMS) patients, besides analysing the impact on different aspects of quality of life. Methods A randomized, single-blind, clinical trial was performed among 20 patients with BMS. Photobiomodulation was applied in the study group (n = 10) with a dose of 12 J/cm2 during 10 sessions, comparing with a placebo group (n = 10) with the laser turned off. Pain was assessed using the visual analogue scale (VAS) before starting each treatment session, and at the 1-month and 4-month follow-up appointments. Some validated questionnaires for general health were also complete SF-36, OHIP-14, Epworth, SCL 90-R and McGill. Results All patients (n = 10) in the study group improved their pain ending treatment and remaining among 90% (n = 9) in the 4-month follow-up. Significant improvement was found in the study group in some sections of McGill questionnaire, Epworth scale, and SCL 90-R at the end of the treatment and in the 1-month and 4-month follow-ups. Conclusions Photobiomodulation seems to be effective in reducing pain in patients with BMS, as well as, having a positive impact on the psychological state of these patients.Coronavirus disease 2019 (COVID‐19) has rapidly spread to more than 200 countries and areas. As of May 11, 2020, more than 4 million cases have been confirmed globally and more than 280000 deaths have been recorded. In China, Italy and America, the mortality was 5.5% (4644/84451), 14.0% (30739/219814) and 6.1% (78652/1298287), respectively.1Transient phosphenium and arsenium ions, generated by fluoride abstraction of bis( m -terphenyl)fluoropnictogens, underwent intramolecular electrophilic attack prior to methyl group migration and gave rise to isolable 9-phospha- and 9-arsena-fluorenium ions.Avulsion of permanent teeth is one of the most serious dental injuries. Prompt and correct emergency management is essential for attaining the best outcome after this injury. The International Association of Dental Traumatology (IADT) has developed these Guidelines as a consensus statement after a comprehensive review of the dental literature and working group discussions. It represents the current best evidence and practice based on that literature search and expert opinions. Experienced researchers and clinicians from various specialties and the general dentistry community were included in the working group. In cases where the published data did not appear conclusive, recommendations were based on consensus opinions or majority decisions of the working group. They were then reviewed and approved by the members of the IADT Board of Directors. TGF-beta activation The purpose of these Guidelines is to provide clinicians with the most widely accepted and scientifically plausible approaches for the immediate or urgent care of avulsed permanent teeth. The IADT does not, and cannot, guarantee favorable outcomes from adherence to the Guidelines. However, the IADT believes that their application can maximize the probability of favorable outcomes.High mortality events due to Streptococcus equi subspecies zooepidemicus (Streptococcus zooepidemicus) in swine have not previously been reported in the United States. In September and October 2019, outbreaks with swine mortality up to 50% due to S. zooepidemicus septicaemia were reported in Ohio and Tennessee. Genomic epidemiological analysis revealed that the eight outbreak isolates were clustered together with ATCC 35246, a Chinese strain caused outbreaks with high mortality, also closely related to three isolates from human cases from Virginia, but significantly different from an outbreak-unrelated swine isolate from Arizona and most isolates from other animal species. Comparative genomic analysis on two outbreak isolates and another outbreak-unrelated isolate identified several genomic islands and virulence genes specifically in the outbreak isolates only, which are likely associated with the high mortality observed in the swine population. These findings have implications for understanding, tracking and possibly preventing diseases caused by S. zooepidemicus in swine.Background Severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2; COVID-19), which causes coronavirus disease 2019, is highly contagious and a particularly popular problem in all around the world and also in all departments of every hospital. Aims Protecting the well-being of the aesthetic dermatologists while providing a sufficient workforce is vital for pandemic planning. Results and conclusions In this article, we will discuss this problem from an aesthetic dermatology aspect and we will review whether these procedures are safe or not.Solid organ transplant (SOT) recipients may be at risk for severe COVID-19. Data on the clinical course of COVID-19 in immunosuppressed patients are limited, and the effective treatment strategy for these patients is unknown. We describe our institutional experience with COVID-19 in SOT. Demographic, clinical, and treatment data were extracted from the electronic patient files. A total of 23 SOT transplant recipients suffering from COVID-19 were identified (n = 3 heart; n = 15 kidney; n = 1 kidney-after-heart; n = 3 lung, and n = 1 liver transplant recipient). The presenting symptoms were similar to nonimmunocompromised patients. Eighty-three percent (19/23) of the patients required hospitalization, but only two of these were transferred to the intensive care unit. Five patients died from COVID-19; all had high Clinical Frailty Scores. In four of these patients, mechanical ventilation was deemed futile. In 57% of patients, the immunosuppressive therapy was not changed and only three patients were treated with chloroquine. Most patients recovered without experimental antiviral therapy. Modification of the immunosuppressive regimen alone could be a therapeutic option for SOT recipients suffering from moderate to severe COVID-19. Pre-existent frailty is associated with death from COVID-19.Aims To investigate the longitudinal association of microalbuminuria with overactive bladder (OAB). Methods This longitudinal study investigated 561 participants of the Iwaki Health Promotion Project in both 2015 and 2019 in Japan. Microalbuminuria and OAB symptoms were assessed using the urine albuminuria creatinine ratio (ACR) and the overactive bladder symptom score (OABSS), respectively. Urine ACR was defined as high if ≥9.3 mg/gCr. Differences in OABSS between 2015 and 2019 were evaluated as ∆OABSS. Participants were divided into two groups according to ΔOABSS high (ΔOABSS > 1) and control (≤1). We used baseline data acquired in 2015, such as urine ACR, the Pittsburgh Sleep Quality Index (PSQI), and arterial stiffness expressed by brachial-ankle pulse wave velocity (baPWV). Predictive factors of a ΔOABSS > 1 were assessed by multivariable logistic regression analysis. Results This study included 332 women and 229 men. Of those, 86 (34 males and 52 females) were classified into the ΔOABSS > 1 group. There were significant group differences in age, renal function, and hemoglobin A1c. Participants in the ΔOABSS > 1 had a higher prevalence of PSQI > 5, baPWV ≥ 1400 seconds/cm, and urine ACR ≥ 9.3 mg/gCr (49% vs 20%, P = .001) than those in the control group. Multivariable analysis revealed that PSQI > 5 (odds ratio [OR], 2.57; 95% confidence interval [CI], 1.15-4.60; P = .002) and urine ACR ≥ 9.3 mg/gCr (OR, 1.93; 95% CI, 1.15-3.23; P = .013) were independent risk factors for ΔOABSS > 1. Conclusions Microalbuminuria may be an independent risk indicator for OAB symptom exacerbation.Despite the best treatment, approximately 10% of fractures still face undesirable repair. Recently, many studies have focused on the importance of macrophages in bone repair; however, the cellular mechanisms by which they work are not yet fully understood. In this study, we explored the functions of macrophage G-protein-coupled receptor interacting protein 1 (GIT1) in healing a tibial monocortical defect model. Using GIT1flox/flox Lyz2-Cre (GIT1 CKO) mice, we observed that a GIT1-deficiency in the macrophages led to an exacerbation of interleukin 1β (IL1β) production, more M1-like macrophage infiltration, and impaired intramembranous ossification in vivo. The results of in vitro assays further indicated that the macrophage GIT1 plays a critical role in several cellular processes in response to lipopolysaccharide (LPS), such as anti-oxidation, IL1β production alleviation, and glycolysis control. While GIT1 has been recognized as a scaffold protein, our data clarified that GIT1-mediated extracellular-signal-regulated kinase (ERK) phosphorylation could activate nuclear factor (erythroid-derived 2)-like 2 (NRF2) in macrophages after LPS treatment. Moreover, we demonstrated that macrophage GIT1-activated ERK/NRF2 negatively regulates the 6-phosphofructo-2-kinase/fructose-2, 6-biphosphatase 3 (PFKFB3), facilitating the decrease of glycolysis. Our findings uncovered a previously unrecognized role of GIT1 in regulating ERK/NRF2 in macrophages to control the inflammatory response, suggesting that GIT1 could be a potential target to improve bone regeneration.
