One-Stage Nerve Repair for Post-Ganglionic Brachial Plexus Injury by Using Ipsilateral Ruptured Ulnar Nerve as a Donor for Axillary Artery Rupture with Open Wound.

Open axillary arterial injury is life-threatening, and upper-extremity reperfusion must be performed within approximately 6 h. We present the case of a patient who underwent reperfusion of the upper limb and nerve reconstruction of the post-ganglionic brachial plexus injury in one stage while maintaining stable vital signs. The injury was an avulsion with no fracture.

Platypnea-orthodeoxia syndrome developed with the progression of pulmonary parenchymal involvement: A case report.

Unlabelled: Platypnea-orthodeoxia syndrome (POS) attributed to patent foramen ovale (PFO) can be caused by a variety of clinical conditions. A 70-year-old woman was admitted to our hospital for further evaluation of POS. Her symptoms developed along with the spread of infiltrative shadows in both lower lung fields during the preceding 2 years.

Divergent and chemoselective deuteration of -unsubstituted imidazoles enabled by precise acid/base control.

Herein, we report acid/base-controlled and divergent deuteration of -unsubstituted imidazoles in an imidazole-selective manner. This protocol enabled the deuteration of not only the 4-arylimidazoles but also the 2-arylimidazoles without labelling the aromatic rings. We demonstrated the advantages of this protocol by the synthesis of deuterated pharmaceuticals, which is difficult to achieve by means of transition metals.

Balloon aortic valvuloplasty bridge to transcatheter aortic valve replacement is associated with worse in-hospital mortality.

Background: Balloon aortic valvuloplasty (BAV) has gained renewed interest as a bridge to transcatheter aortic valve replacement (TAVR) for patients with aortic stenosis (AS). However, it is unclear whether they patients should undergo TAVR directly or receive a staged bridge to BAV before TAVR is unclear. We used a national database to examine the association between BAV and TAVR in patients with TAVR and its effect on in-hospital mortality.

Dynamic Pulmonary Vein Stenosis After Left Pneumonectomy.

Pulmonary vein stenosis might be caused by mediastinal migration into the vacated pleural space after pneumonectomy. In a patient complaining of worsening dyspnea in the left lateral decubitus position after left pneumonectomy, transthoracic echocardiography during different postures revealed pulmonary vein stenosis that worsened in the left lateral position.

Fructooligosaccharides Intake during Pregnancy Improves Metabolic Phenotype of Offspring in High Fat Diet-Induced Obese Mice.

Scope: Obesity and metabolic diseases are closely associated, and individuals who become obese are also prone to type 2 diabetes and cardiovascular disorders. Gut microbiota is mediated by diet and can influence host metabolism and the incidence of metabolic disorders. Recent studies have suggested that improving gut microbiota through a fructooligosaccharide (FOS)-supplemented diet may ameliorate obesity and other metabolic disorders.

Photoreaction products of extract from the fruiting bodies of Polyozellus multiplex.

Photochemical reactions are powerful tools for synthesizing organic molecules. The input of energy provided by light offers a means to produce strained and unique molecules that cannot be assembled using thermal protocols, allowing for the production of immense molecular complexity in a single chemical step. Furthermore, unlike thermal reactions, photochemical reactions do not require active reagents such as acids, bases, metals, or enzymes.

A Case of Sinus Venosus Atrial Septal Defect: Physical Examination as a Diagnostic Clue.

An atrial septal defect (ASD) may be detected later in life due to its asymptomatic status. We report a case of superior sinus venosus ASD, a rare type of ASD, in which bedside physical examination was useful for the diagnosis. A 72-year-old male was referred to cardiology during the treatment of a cerebral infarction.

Right ventricular dilatation: echocardiographic differential diagnosis.

The initial means of detecting right ventricular (RV) dilatation is often transthoracic echocardiography (TTE), and once the presence of RV dilatation is suspected, there is the possibility of RV volume overload, RV pressure overload, RV myocardial disease, and even nonpathological RV dilatation. With respect to congenital heart disease with RV volume overload, defects or valvular abnormalities can be easily detected with TTE, with the exception of some diseases. Volumetric assessment using three-dimensional echocardiography may be useful in determining the intervention timing in these diseases.

Status of epilepsy care delivery and referral in clinics, hospitals, and epilepsy centers in Japan: A nationwide survey.

Objective: Collaboration among medical facilities is crucial to deliver comprehensive epilepsy care to a diverse and large population of people with epilepsy. We conducted a survey among medical facilities of various sizes throughout Japan to investigate the status of epilepsy care delivery, functioning, and referral.

Methods: With the cooperation of the Japan Neurological Society (1428 facilities), Japanese Neurosurgical Society (3489 specialists), and Epilepsy Care Network (948 facilities), a questionnaire was mailed to 5865 locations that provide epilepsy care in Japan.

Mitral valve leaflet stiffness predicts residual mitral regurgitation after transcatheter edge-to-edge mitral valve repair.

Background: Residual regurgitation after transcatheter edge-to-edge mitral valve repair (TMVR) is a predictor of poor prognosis in patients with functional mitral regurgitation (FMR). This study sought to identify the mitral valve (MV) parameters measured by three-dimensional transesophageal echocardiography (3D-TEE) and MV leaflet features that predict residual mitral regurgitation (MR) after TMVR in patients with FMR.

Methods: Consecutive patients with FMR who underwent TMVR were classified into two groups based on the degree of residual MR just after TMVR: < 2+ in the optimal MR reduction group and ≥ 2+ in the suboptimal MR reduction group.

A Case of Docetaxel-Induced Left Ventricular Outflow Tract Obstruction.

Docetaxel, a taxoid chemotherapy agent, may induce fluid retention. We present a case of metastatic breast cancer in which high output caused by docetaxel-induced fluid retention resulted in heart failure due to left ventricular outflow tract (LVOT) obstruction. A 58-year-old woman presented with exertional dyspnea and anasarca.

Physical Examination as a Clue to Transthyretin Cardiac Amyloidosis: A Case Report.

Transthyretin (ATTR) cardiac amyloidosis has recently received increased attention; however, the diagnosis is often delayed. We present a case of ATTR cardiac amyloidosis in which a comprehensive history-taking and focused physical examination played an important role in establishing the diagnosis. A 75-year-old man was referred to the cardiology department for left ventricular hypertrophy on electrocardiography.

Infective Endocarditis Caused by Staphylococcus lugdunensis.

Staphylococcus lugdunensis, a minor species of coagulase-negative staphylococci, has attracted attention because of its formidable pathogenicity. We present a case of infective endocarditis (IE) caused by S. lugdunensis in a 72-year-old woman with a history of breast cancer and metastases who presented with fever.

A gold-complex initiated functionalization of biologically active polyphenols applied to a F-labeled chemical probe.

(-)-Epigallocatechin gallate (EGCG), a key component of green tea, exerts therapeutic anticancer and antiallergic properties through its binding to the 67 kDa laminin receptor. The functionalization of EGCG is a promising strategy for creating new drug candidates and chemical probes. In our study, we developed a method for effectively modifying the A ring of EGCG through an electrophilic aromatic substitution with amidomethyl 2-alkynylbenzoates initiated with a gold complex.

Systolic Ejection Murmurs Due to Unruptured Aneurysm of the Sinus of Valsalva.

Aneurysm of the sinus of Valsalva is a rare condition with variable clinical presentation. We present a case of an unruptured aneurysm of the right sinus of Valsalva, in which a systolic ejection murmur was instrumental in the diagnosis. An asymptomatic 72-year-old man was referred to the cardiology department because of a heart murmur.

Doppler Underestimates Transvalvular Gradient Measured by Catheterization in Patients With Severe Aortic Stenosis.

We sought to clarify characteristics of patients with severe aortic stenosis (AS) in whom transvalvular mean pressure gradient (MPG) was underestimated with Doppler compared with catheterization. Study subjects included 127 patients with severe AS who underwent transcatheter aortic valve implantation. Between subjects with Doppler MPG underestimation ≥10 mm Hg (group U) and those without (group C), we retrospectively compared echocardiographic parameters and aortic valve calcification score using the Agatston method.

Impact of Arterial Calcification of the Lower Limbs on Long-Term Clinical Outcomes in Patients on Hemodialysis.

Lower limbs' arterial calcification is significantly associated with the clinical severity of lower extremity artery disease (LEAD) in patients undergoing hemodialysis (HD). However, the association between arterial calcification of the lower limbs and long-term clinical outcomes in patients on HD has not been elucidated. Calcification scores of the superficial femoral artery (SFACS) and below-knee arteries (BKACS) were quantitatively evaluated in 97 HD patients who were followed for 10 years.

[Distal Gastrectomy under Management of Intra-Aortic Balloon Pumping Therapy for an Elderly Patient with Carcinomatous Pyloric Stenosis Complicated by Severe Coronary Stenosis].

This case involved an 82-year-old man with a history of diabetes mellitus and myocardial infarction. He was undergoing treatment with 2 oral antiplatelet agents. The patient presented to our hospital for carcinomatous pyloric stenosis caused by type 4 advanced gastric cancer.

Left ventricular hypertrophy as a predictor of cardiovascular outcomes after transcatheter aortic valve replacement.

Aims: This study aimed to clarify the relationship between cardiovascular prognosis and left ventricular hypertrophy (LVH) in patients with severe aortic stenosis who underwent transcatheter aortic valve replacement (TAVR) and to investigate the relationship between cardiac sympathetic nerve (CSN) function and these factors using I-metaiodobenzylguanidine scintigraphy.

Methods And Results: In this single-centre, retrospective observational study, 349 patients who underwent TAVR at our institution between July 2017 and May 2020 were divided into two groups: those with severe LVH pre-operatively [severe LVH (+) group] and those without LVH pre-operatively [severe LVH (-) group]. The rates of freedom from cardiovascular events (cardiovascular death and heart failure hospitalization) were compared.
