Human are increasingly exposed to various types of engineered nanomaterials (ENMs) via dietary ingestion of nano-enabled food products, but these ENMs' impact on the gut bacteria health is still poorly understood. Current efforts in understanding the impact of these ENMs are hampered by their optical interferences in conventional quantification and viability assays, such as optical density and whole cell fluorescence staining assays. Therefore, there is a need to develop a more reliable bacteria quantification method in the presence of ENMs to effectively screen the potential adverse effects arising from the exposure of increasing ENMs on human gut microbiome. In this study, we developed a DNA-based quantification (DBQ) method in a 96-well plate format. Post-spiking method was used to correct the interference from ENMs on the reading. We showed the applicability of this method for several types of ENMs, i.e., cellulose nanofiber (CNF), graphene oxide (GO), silicon dioxide (SiO2), and chitosan, both in pure bacterial culture and in vitro human gut microbiome community. The detection limit for the highest dosing of CNF, GO, SiO2, and chitosan ENMs was approximately 0.18, 0.19, 0.05, and 0.24 as OD600, respectively. The method was also validated by a dose response experiment of E. coli with chitosan in the course of 8 hr. We believe that this method has great potential to be used in screening the effect of ENMs on the growth of gut bacteria or any other in vitro models and normalization for metabolites or proteins analysis.

Patients with borderline personality disorder (BPD) experience difficulties in emotional awareness (alexithymia), and often develop dissociative symptoms, which may reflect broader deficits in interoceptive awareness. Whether this is associated with alterations in cortical processing of interoception is currently unknown.

We utilized an electrophysiological marker of interoception, i.e. heartbeat-evoked potentials (HEP), and examined its relationship with electrocardiographic correlates of autonomic nervous system (ANS) functioning (heart rate variability), and with self-report measures of alexithymia, dissociation and borderline symptom severity in patients with BPD.

Individuals with BPD had higher HEP amplitudes over frontal electrodes compared to healthy controls. Sympathetic ANS activity was greater in BPD patients than in controls. Across groups, HEP amplitudes were associated with parasympathetic activity over central electrodes and correlated with alexithymia over frontal electrodes.

These findings support the idea that difficulties in emotional awareness in BPD are reflected in altered frontal electrophysiological markers of interception. Therefore, emotional awareness can be understood as failures of modulation between interoceptive and exteroceptive attention. mTOR inhibitor cancer Future research may aim to investigate whether altered interoception and its electrophysiological correlates are malleable by therapeutic intervention.

This usually occurs in osteoarthritis, but is relatively rare in rheumatoid arthritis. This is a report of recurrent hemarthrosis after total knee arthroplasty in a rheumatoid arthritis patient. An 85-year-old woman with rheumatoid arthritis had received total knee arthroplasty without acute complications. At 6 months after surgery, the first hemarthrosis occurred and an initial conservative treatment failed. Contrast computed tomography showed prominent synovial enhancement in the superior lateral suprapatellar pouch. Selective catheterization revealed an abnormal hyperemic blush supplied from the branches of the superior lateral genicular artery. After embolization with N-butyl-2-cyanoacrylate, abnormal staining of the synovium diminished and knee swelling and pain disappeared without complications. Selective embolization is favorable for successful treatment of recurrent hemarthrosis after total knee arthroplasty in patients with rheumatoid arthritis.Nasal spindle cell rhabdomyosarcoma is very rare. The tumor is sometimes confused with other spindle cell tumors. We herein report a case of nasal spindle cell tumor in a 62-year-old woman. The patient first presented herself to a medical doctor's office after an episode of left epistaxis. An intranasal tumor was found and resected. The tumor was composed of spindle cells, and she was diagnosed with desmoid-type fibromatosis. Five years after the initial episode, an intranasal tumor was found again. The tumor showed a fascicular growth pattern with high cellularity and was predominantly composed of spindle cells. Scattered eosinophilic rhabdomyoblasts were also observed. She was diagnosed with spindle cell rhabdomyosarcoma. This is a unique case report not only because nasal spindle cell rhabdomyosarcoma is very rare but also because the tumor was initially diagnosed as desmoid-type fibromatosis. It is important to consider spindle cell rhabdomyosarcoma as a differential diagnosis of nasal spindle cell tumors.We present a case series of three patients with COVID-19 who were admitted to our intensive care unit due to acute respiratory distress syndrome, brain infarction, pulmonary embolism, and antiphospholipid antibodies. We applied therapeutic plasma exchange on all cases. On intensive care unit admission, all patients had low ( less then 10) Glasgow Coma Scale, and central nervous imaging showed multiple brain infarctions. COVID-19 was confirmed by reverse transcriptase polymerase chain reaction assays. Patients underwent rescue therapeutic plasma exchange using the Spectra OptiaTM Apheresis System (Terumo BCT Inc., USA), which operates with acid-citrate dextrose anticoagulant as per Kidney Disease Improving Global Outcomes 2019 guidelines. A dose of 1.5 plasma volume was used for the first dose and then 1 plasma volume daily for a total of five doses. Plasma was replaced with Octaplas LG® (Octapharma AG, USA), which is an artificial fresh frozen plasma product that has undergone viral inactivation by prion reduction technology. We administered ARDS-net/prone positioning ventilation, empiric antiviral treatment, therapeutic anticoagulation, and intensive care unit supportive care. Laboratory tests showed lymphocytopenia; elevated levels of D-dimer, fibrinogen, total bilirubin, C-reactive protein, lactate dehydrogenase, and ferritin; as well as low levels of ADAMTS-13 activity and antibody. Serology tests depicted positive IgM and IgG antiphospholipid antibodies (anti-cardiolipin and anti-β2-glycoprotein I antibodies). No side effects of therapeutic plasma exchange were recorded. After the completion of therapeutic plasma exchange, patients improved clinically and gradually recovered neurologically (after 27-32 days). To conclude, in life-threatening COVID-19, especially when immune dysregulation features such as antiphospholipid antibodies exist, therapeutic plasma exchange could be an effective rescue therapy.Dermatomyositis is an inflammatory myopathy presenting with characteristic cutaneous eruption and may be accompanied by proximal muscle weakness. Dermatomyositis may represent a paraneoplastic syndrome in 15%-25% of cases and has rarely been associated with endometrial cancer. Herein, we report a case of dermatomyositis with anti-TIF1γ antibodies as the first clinical manifestation revealing isolated para-aortic lymphadenopathy metastatic recurrence of endometrial cancer after 4 years of remission. Interestingly, dermatomyositis rash completely resolved after lymphadenectomy. This case highlights the importance of early dermatomyositis diagnosis, thorough cancer screening, and that cancer treatment may, in some patients, foster dermatomyositis remission.Knowledge of lung ultrasound characteristics of coronavirus disease 2019 pneumonia might be useful for early diagnosis and clinical monitoring of patients, and lung ultrasound can help to control the spread of infection in healthcare settings. In this case report, a 36-year-old man with severe acute respiratory syndrome coronavirus 2 infection was diagnosed by reverse transcription-polymerase chain reaction testing of a nasopharyngeal swab. The lung ultrasound findings for this patient were the interstitial-alveolar damage showing bilateral, diffuse pleural line abnormalities, subpleural consolidations, white lung areas and thick, irregular vertical artifacts. When the patient recovered from the severe acute respiratory syndrome coronavirus 2 infection, lung ultrasound images showed a normal pleural line with A-lines regularly reverberating. Performing lung ultrasound at the bedside minimizes the need to move the patient, thus reducing the risk of spreading infection among healthcare staff. Lung ultrasound is useful for early diagnosis and evaluation of the severity of coronavirus disease 2019 pneumonia and for monitoring its progress over the course of the disease.In this case report, we discuss the presentation of retinopathy of prematurity in triplets born at 25 + 3 weeks gestational age of whom each had a different birth weight, weight gain and treatment requirements. Triplet A weighed 800 g and his retinopathy of prematurity had resolved with no intervention. Triplet B weighed 630 g at birth and he required bilateral intravitreal ranibizumab injection at 32 + 6 weeks. Triplet C weighed 520 g and required bilateral intravitreal ranibizumab injection at 36 weeks, but after 5 weeks he had recurrence which was treated with bilateral diode laser. Triplet C had the poorest weight gain. The main differences between the triplets are the birth weight and the weight gain. Furthermore, refraction was performed at 10 months; triplet A had a hyperopia of +1.25 spherical equivalent in both eyes, triplet B had mild myopia of -0.25 spherical equivalent and triplet C had a myopia of -3.00 spherical equivalent in the right eye and -2.75 spherical equivalent in the left eye.Myoepitheliomas account for approximately 1.5% of all salivary gland tumors and arise most frequently from the parotid gland. Recently, a new myoepithelioma variant, called mucinous myoepithelioma, has attracted widespread attention. These tumors are recognized as a unique subtype of myoepithelioma, characterized by the presence of abundant mucin. We herein report the findings of an 86-year-old Japanese woman who presented with a hard mass of the right parotid gland behind her right ear which was gradually increasing in size. The patient had undergone a fine-needle aspiration biopsy 4 years earlier, and a cytological evaluation of a biopsy specimen had shown features of pleomorphic adenoma. A resection was thus performed and the tissue was found to be an encapsulated, soft and solid mass, and the cut surface was observed to be a capsulated and well-defined tumor lesion with myxoid-looking foci of gray-white coloration. Microscopic examination revealed that this lesion was composed of a proliferation of bland-looking epithelial and myoepithelial cells, arranged in a solid or reticular growth fashion in an abundant myxomatous or hyalinized stroma.
