Circulating Inhibitor against Factor X: A Rare Cause of Hemorrhagic Diathesis

Acquired coagulopathies resulting from factor X deficiency are rare and typically associated with amyloidosis or plasma cell dyscrasia. Factor X plays a pivotal role in the coagulation cascade, converting prothrombin into thrombin and facilitating the formation of fibrinogen and thrombus. While its occurrence following common infections is extremely rare, isolated cases have been documented. We present a rare case of bleeding diathesis in a patient with community-acquired pneumonia, where prolonged activated partial thromboplastin time (aPTT) and prothrombin time (PT) led to the diagnosis of an infectious-triggered acquired circulating inhibitor targeting factor X. Prompt treatment with methylprednisolone effectively controlled the inhibitor without recurrence. This case report provides insights into the diagnostic strategies, differential algorithm, and therapeutic approaches for managing this rare coagulopathy

HOMO Energy-Level Lifting in p-Type O-Doped Graphenoids: Synthesis of Electrochromic Alkoxy-Decorated Xanthenoxanthenes

Abstract A series of novel O-doped polycyclic aromatic hydrocarbons, bearing a different number of electron-donating alkoxy substituents, has been prepared using a novel copper-promoted anaerobic protocol for the cyclisation of highly electron rich peri-xanthenoxanthene molecular modules. The effect of the number and position of the alkoxy substituents on the optoelectronic properties has thus been investigated, unveiling p-type semiconducting properties. All molecules displayed a significant colour change upon oxidation, suggesting that these compounds can be used to devise chromogenic materials to engineer electrochromic devices

SUN-PO316: Impact of Protein Intake and High-Fat Diet on Muscle Protein Synthesis and Lipid Infiltration in Relation to Aging in Rats

Part of special issue: Abstracts of the 41st ESPEN Congress, Krakow, Poland, 31 August–3 September, 2019International audienceRationale: Ectopic lipid deposition impairs muscle anabolic responseespecially during aging. We hypothesized that the anabolic efficiencyof dietary protein in skeletal muscle might be affected by high-fat diet.The objective of the study was to investigate muscle protein synthesisin response totwolevels of protein intake combined totwo levels of fatintake. Methods: Two groups of sixty adult and forty-nine old male Wistarrats were randomly divided into four groups: isocaloric standard diet (12% protein, 14% lipid, as STD12); isocaloric standard (high-protein)diet (25% protein, 14% lipid, STD25); hypercaloric high-fat (normal-protein) diet (12% protein, 45% lipid, HFD12); and hypercaloric high-fat (high-protein) diet (25% protein, 45% lipid, HFD25). The nutritionalintervention lasted 10 weeks. The fractional synthesis (FSR) andabsolute synthesis rates (ASR) of mixed muscle proteins werecalculated using isotopically labelled13C-Valine incorporation intibialis anterior (TA). Muscle lipid content was assessed usingchromatography method. Results: Rats in the high-fat diet groups self-limited their food intake,so that energy intake was not different among the groups. Regardlessof dietary intervention, TAweight was lower in old groups compared totheir adult counterparts (all p values Conclusions: Aging is characterized by reduced muscleweight despiteincreased FSR, suggesting specific alterations in the nutritionalregulation of muscle protein turnover. In isocaloric conditions, higherprotein intake modulates muscle lipid infiltration, without improvingage-related anabolic resistance in old rats fed a high-fat diet
