A Case of Stanford Type A Acute Aortic Dissection With Preoperative Extensive Cerebral Infarction Successfully Treated Surgically.

Patients with organ malperfusion from acute aortic dissection (AAD) have poor outcomes, and the surgical indications for patients with AAD complicated by extensive cerebral infarction have not been established. Here, we report a successfully treated surgical case of a patient with cerebral infarction and Stanford type A, AAD. A 77-year-old man was admitted to the hospital with a chief complaint of left paresis.

Thoracoscopic Right Lower Lobectomy in a Patient With a Common Trunk of the Right Pulmonary Veins.

Varied branching patterns of the pulmonary veins are widely known; however, the common trunk of the right pulmonary veins is sparsely described. We report the details of a right lower lobectomy in a patient with a common trunk of the right pulmonary veins. Besides an attentive interpretation of computed tomography images, 3-dimensional reconstruction aids in the preoperative recognition of this anomaly.

Early Life Polychlorinated Biphenyl 126 Exposure Disrupts Gut Microbiota and Metabolic Homeostasis in Mice Fed with High-Fat Diet in Adulthood.

Evidence supports the potential influence of persistent organic pollutants (POPs) on the pathogenesis and progression of obesity and diabetes. Diet-toxicant interactions appear to be important in diet-induced obesity/diabetes; however, the factors influencing this interaction, especially the early life environmental exposure, are unclear. Herein, we investigated the metabolic effects following early life five-day exposure (24 μg/kg body weight per day) to 3,3',4,4',5-pentacholorobiphenyl (PCB 126) at four months after exposure in mice fed with control (CTRL) or high-fat diet (HFD).

Adverse event profiles of microscopic colitis in the Japanese Adverse Drug Event Report (JADER) database.

Microscopic colitis (MC) is a chronic inflammatory bowel disease that is characterized by nonbloody watery diarrhea. The epidemiology in Japan differs from that in Europe and the United States, but little information is available from epidemiological surveys of MC in Japan. This study aimed to provide a new hypothesis regarding the factors associated with MC by using the Japanese Adverse Drug Event Report (JADER) database.

Syphilitic osteomyelitis in a patient with HIV and cognitive biases in clinical reasoning: A case report.

Rationale: Diagnosing multifactorial, multidimensional symptoms unexplained by presumptive diagnosis is often challenging for infectious disease specialists.

Patient Concerns: We report a rare case of a 30-year-old Japanese bisexual man with a history of virally suppressed human immunodeficiency virus and syphilis infections who developed chest pain and an erosive lesion under the lower midline jaw.

Diagnosis: Imaging examinations revealed erosive lesions on the sternum and left the ninth rib.

The neuroanatomy of social trust predicts depression vulnerability.

Trust attitude is a social personality trait linked with the estimation of others' trustworthiness. Trusting others, however, can have substantial negative effects on mental health, such as the development of depression. Despite significant progress in understanding the neurobiology of trust, whether the neuroanatomy of trust is linked with depression vulnerability remains unknown.

Adverse event profiles of hypomagnesemia caused by proton pump inhibitors using the Japanese Adverse Drug Event Report (JADER) Database.

Proton pump inhibitors (PPIs) are commonly used for the prevention or treatment of gastric ulcers, but they can induce hypomagnesemia. Little is known about the onset duration and risk factors related to patient characteristics of this adverse event in Japanese patients. Therefore, we analyzed the time-to-onset of PPI-induced hypomagnesemia and evaluated the association between hypomagnesemia and PPIs using the Japanese Adverse Drug Event Report (JADER) database.

Non-canonical Regulation of EGFR by the Air Pollutant 9,10-Phenanthrenequinone.

9,10-Phenanthrenequinone (9,10-PQ), a polycyclic aromatic hydrocarbon that is present in air pollutants, such as diesel exhaust gas and PM2.5, causes the production of excess reactive oxygen species. 9,10-PQ was recently shown to induce the activation of epidermal growth factor receptor (EGFR) by inhibiting protein tyrosine phosphatase 1B.

Dopamine activates astrocytes in prefrontal cortex via α1-adrenergic receptors.

The prefrontal cortex (PFC) is a hub for cognitive control, and dopamine profoundly influences its functions. In other brain regions, astrocytes sense diverse neurotransmitters and neuromodulators and, in turn, orchestrate regulation of neuroactive substances. However, basic physiology of PFC astrocytes, including which neuromodulatory signals they respond to and how they contribute to PFC function, is unclear.

Association of Statin Adherence With the Development of Nonalcoholic Fatty Liver Disease: A Nested Case-Control Study Using a Japanese Claims Database.

Background: Statins are expected to have beneficial effects on nonalcoholic fatty liver disease (NAFLD); however, evidence remains insufficient.

Objective: In this study, we aim to investigate the association between statin adherence and NAFLD development.

Methods: We conducted a nested case-control study of statin users using the Japan Medical Data Center administrative claims database (January 2005 to January 2020).

Juvenile Membranous Nephropathy Developed after Human Papillomavirus (HPV) Vaccination.

A 16-year-old girl with no history of renal disease had a fever of 38 °C after her second HPV vaccination and was identified as positive for proteinuria. As she maintained urinary protein of 3.10 g/gCr and 5-9 urinary red blood cells/HPF, a renal biopsy was performed and small spikes on PAM staining with the granular deposition of IgG1++ and IgG3+ on the glomerular capillary wall were discovered by immunofluorescence, although PLA2R immunostaining was negative.

Infant Stimulation Induced a Rapid Increase in Maternal Salivary Oxytocin.

Oxytocin (OT) is a neuropeptide involved in human social behaviors and reproduction. Non-invasive OT levels in saliva have recently roused interest as it does not require a specialized medical setting. Here, we observed one woman's basal serum and saliva OT from pregnancy to 1 year postpartum to track OT concentration changes over this period.

Long-Term Survival after Linac-Based Stereotactic Radiosurgery and Radiotherapy with a Micro-Multileaf Collimator for Brain Metastasis.

Background: this study aimed to evaluate the prognostic factors associated with long-term survival after linear accelerator (linac)-based stereotactic radiosurgery (SRS) and fractionated stereotactic radiotherapy (fSRT) with a micro-multileaf collimator for brain metastasis (BM).

Methods: This single-center retrospective study included 226 consecutive patients with BM who were treated with linac-based SRS or fSRT with a micro-multileaf collimator between January 2011 and December 2018. Long-term survival (LTS) was defined as survival for more than 2 years after SRS/fSRT.

Endovascular vertebral artery orifice angioplasty for the prevention of acute ischemic stroke following vertebral artery stump syndrome.

Background: Vertebral artery stump syndrome (VASS) involves repeated acute ischemic stroke (AIS) in the posterior circulation following vertebral artery (VA) orifice occlusion. The presence of VA orifice occlusion makes endovascular thrombectomy (EVT) difficult to achieve and leads to posterior circulation stroke with unfavorable functional outcomes. Here, we report a case of endovascular VA orifice angioplasty for the right VA pseudo-occlusion to prevent AIS following VASS pathology.

Expression of ATP-binding cassette transporter A1 is induced by nerve injury and its deficiency affects neurite tip morphology and elongation in cultured neurons.

Axonal regeneration requires changes in the lipid dynamics of the axon membrane for growth and extension. Here, we examined the expression of genes associated with lipid transport after nerve injury. The expression of ATP-binding cassette transporter-A1 (ABCA1), which participates in the transport of cholesterol from the plasma membrane, was markedly upregulated in motor and sensory neurons after nerve injury.
