29 mmol/L [-41.23 mg/dL], P less then 0.0001). Incidence of documented symptomatic hypoglycemia (≤3.9 mmol/L [70 mg/dL]) was higher with iGlarLixi (13.0% vs. 2.5%) through week 26, with no severe hypoglycemic events in either group. Incidence of gastrointestinal events through week 52 was lower with iGlarLixi (36.0% vs. 50.0%), and rates of treatment-emergent adverse events were similar. CONCLUSIONS This phase 3 study demonstrated superior glycemic control and fewer gastrointestinal adverse events with iGlarLixi than with Lixi, which may support it as a new treatment option for Japanese patients with T2DM that is inadequately controlled with OADs. © 2020 by the American Diabetes Association.OBJECTIVE To examine the association between manganese intake and the risk of type 2 diabetes in postmenopausal women and determine whether this association is mediated by circulating markers of inflammation. RESEARCH DESIGN AND METHODS We included 84,285 postmenopausal women without a history of diabetes from the national Women's Health Initiative Observational Study (WHI-OS). Replication analysis was then conducted among 62,338 women who participated in the WHI-Clinical Trial (WHI-CT). Additionally, data from a case-control study of 3,749 women nested in the WHI-OS with information on biomarkers of inflammation and endothelial dysfunction were examined using mediation analysis to determine the relative contributions of these known biomarkers by which manganese affects type 2 diabetes risk. RESULTS Compared with the lowest quintile of energy-adjusted dietary manganese, WHI-OS participants in the highest quintile had a 30% lower risk of type 2 diabetes (hazard ratio [HR] 0.70 [95% CI 0.65, 0.76]). A consistent association was also confirmed in the WHI-CT (HR 0.79 [95% CI 0.73, 0.85]). In the nested case-control study, higher energy-adjusted dietary manganese was associated with lower circulating levels of inflammatory biomarkers that significantly mediated the association between dietary manganese and type 2 diabetes risk. Specifically, 19% and 12% of type 2 diabetes risk due to manganese were mediated through interleukin 6 and hs-CRP, respectively. CONCLUSIONS Higher intake of manganese was directly associated with a lower type 2 diabetes risk independent of known risk factors. This association may be partially mediated by inflammatory biomarkers. © 2020 by the American Diabetes Association.OBJECTIVE Recent studies have highlighted the significance of the microbiome in human health and disease. Changes in the metabolites produced by microbiota have been implicated in several diseases. Our objective was to identify microbiome metabolites that are associated with type 2 diabetes. RESEARCH DESIGN AND METHODS 5,181 participants from the cross-sectional Metabolic Syndrome in Men (METSIM) study that included Finnish men (age 57 ± 7 years, BMI 26.5 ± 3.5 kg/m2) having metabolomics data available were included in our study. Metabolomics analysis was performed based on fasting plasma samples. On the basis of an oral glucose tolerance test, Matsuda ISI and Disposition Index values were calculated as markers of insulin sensitivity and insulin secretion. A total of 4,851 participants had a 7.4-year follow-up visit, and 522 participants developed type 2 diabetes. RESULTS Creatine, 1-palmitoleoylglycerol (161), urate, 2-hydroxybutyrate/2-hydroxyisobutyrate, xanthine, xanthurenate, kynurenate, 3-(4-hydroxyphenyl)lactate, 1-oleoylglycerol (181), 1-myristoylglycerol (140), dimethylglycine, and 2-hydroxyhippurate (salicylurate) were significantly associated with an increased risk of type 2 diabetes. These metabolites were associated with decreased insulin secretion or insulin sensitivity or both. Among the metabolites that were associated with a decreased risk of type 2 diabetes, 1-linoleoylglycerophosphocholine (182) significantly reduced the risk of type 2 diabetes. CONCLUSIONS Several novel and previously reported microbial metabolites related to the gut microbiota were associated with an increased risk of incident type 2 diabetes, and they were also associated with decreased insulin secretion and insulin sensitivity. Microbial metabolites are important biomarkers for the risk of type 2 diabetes. © 2020 by the American Diabetes Association.The brain mechanisms underlying the association of hyperglycemia with depressive symptoms are unknown. We hypothesized that disrupted glutamate metabolism in pregenual anterior cingulate cortex (ACC) in type 1 diabetes (T1D) without depression affects emotional processing. Using proton magnetic resonance spectroscopy (MRS), we measured glutamate concentrations in ACC and occipital cortex (OCC) in 13 T1D without major depression (HbA1c=7.1±0.7% [54±7mmol/mol]) and 11 healthy non-diabetic controls (HbA1c=5.5±0.2% [37±3mmol/mol]) during fasting euglycemia (EU) followed by a 60-minute +5.5mmol/l hyperglycemic clamp (HG). Intrinsic neuronal activity was assessed using resting-state blood oxygen level dependent functional MRI to measure the fractional amplitude of low frequency fluctuations in slow-band 4 (fALFF4). Emotional processing and depressive symptoms were assessed using emotional tasks (Emotional-Stroop, Self-Referent-Encoding-Task SRET) and clinical ratings (HAM-D, SCL-90-R), respectively.

Although emerging evidence has suggested a strong link between the pentose phosphate pathway (PPP) and obesity, the role of transketolase (TKT), an enzyme in the non-oxidative branch of the PPP which connects PPP and glycolysis, remains obscure in adipose tissues. In this study, we specifically delete TKT in mouse adipocytes and find no obvious phenotype upon normal diet feeding. However, adipocyte TKT abrogation attenuates high fat diet (HFD)-induced obesity, reduces hepatic steatosis, improves glucose tolerance, alleviates insulin resistance and increases energy expenditure. Mechanistically, TKT deficiency accumulates non-oxidative PPP metabolites, decreases glycolysis and pyruvate input into the mitochondria, leading to increased lipolytic enzyme gene expression and enhanced lipolysis, fatty acid oxidation and mitochondrial respiration. Therefore, our data not only identify a novel role of TKT in regulating lipolysis and obesity, but also suggest limiting glucose-derived carbon into the mitochondria induces lipid catabolism and energy expenditure. © 2020 by the American Diabetes Association.A huge number of commensal bacteria inhabit the intestine, which is equipped with the largest immune system in the body. Recently, the regulation of various physiological functions of the host by these bacteria has attracted attention. In this study, the effects of commensal bacteria on gene expression in colonic epithelial cells (CoECs) were investigated with focus on regulation of DNA methylation. RNA sequencing analyses of CoECs from conventional, germ-free, and MyD88-/- mice indicated that, out of the genes affected by commensal bacteria, those downregulated in a MyD88-independent manner were most frequently observed. Furthermore, when the 5' regions of genes downregulated by commensal bacteria in CoECs were captured using a customized array and immunoprecipitated with the anti-methyl cytosine Ab, a certain population of these genes was found to be highly methylated. Comprehensive analysis of DNA methylation in the 5' regions of genes in CoECs from conventional and germ-free mice upon pull-down assay with methyl-CpG-binding domain protein 2 directly demonstrated that DNA methylation in these regions was influenced by commensal bacteria. Actually, commensal bacteria were shown to control expression of Aldh1a1, which encodes a retinoic acid-producing enzyme and plays an important role in the maintenance of intestinal homeostasis via DNA methylation in the overlapping 5' region of Tmem267 and 3110070M22Rik genes in CoECs. Collectively, it can be concluded that regulation of DNA methylation in the 5' regions of a specific population of genes in CoECs acts as a mechanism by which commensal bacteria have physiological effects on the host.

Nasal endoscopy revealed a sizeable rounded mass covered by a normal-looking mucosa. Imaging studies showed a mass arising from the left middle turbinate that extended throughout the expanse of the anterior skull base. The tumour was resected via an endoscopic endonasal approach. Histopathological examination revealed a psammomatoid juvenile ossifying fibroma. The patient remains free of recurrence after almost 3 years of follow-up. Only four cases of ossifying fibroma with middle turbinate localisation have been reported in the literature so far, with our case representing the fifth and most extensive case. Clinical, radiological and histological findings should all be considered for establishing the correct diagnosis. An endoscopic approach represents an excellent therapeutic option. Long-term clinical and radiological surveillance is required due to the risk of recurrence. © BMJ Publishing Group Limited 2020. No commercial re-use. See rights and permissions.

Commonly referred to as a 'jersey finger' because of its association with tackling sports, the distal aspect of FDP is avulsed from its insertion on the distal phalanx in zone I, with or without a fragment of bone. Because of this classic injury mechanism and pattern, providers may not seek advanced imaging beyond plain radiographs. Although rare, injury to FDP more proximally may occur. More often this injury is associated with a weak underlying tendon because of repetitive microtrauma or anomalous anatomy, for example. We present a case of a closed rupture of the FDP in zone III, and stress the importance of maintaining a high clinical suspicion and the potential use of adjunct ultrasound imaging to localise the site of injury. © BMJ Publishing Group Limited 2020.

We report a case of a 34-year-old man with KS of the skin, oropharynx, lung and rectum. Within the same lung nodule, we discovered significant burden of colesional Cryptococcus neoformans, in the context of a positive asymptomatic cryptococcal antigenemia, which was a previously unreported occurrence. The gold standard of treatment for KS continues to be HAART. The role of chemotherapy is still controversial. In addition, a cryptococcal antigen screen-and-treat approach with fluconazole is still not routinely recommended in the USA to prevent serious meningeal disease despite recent studies showing efficacy and applicability. We discuss both issues here and the outcome of our patient. We also present the patient's own unique perspective in dealing with the ramifications of these diagnoses. © BMJ Publishing Group Limited 2020. No commercial re-use. See rights and permissions.
