Poor survival of dialysis patients with unhealed wounds because of critical limb ischemia: Limb salvage and survival requires wound healing.

Maintenance of blood flow in the wound area is required to heal wounds of critical limb ischemia (CLI) in dialysis patients. However, many dialysis patients have both a stenotic lesion in below-knee blood vessels and a cardiovascular event as complications, and thus, it may be difficult to ensure sufficient blood flow. Therefore, many deaths occur because of problems with wound healing.

Possible pathogenicity of commensal revealed by molecular screening of healthy school children in Indonesia.

Background: Although parasites are still endemic in developing areas, residents in those regions seem not to be affected by the presence of intestinal protozoans. This study aimed to investigate whether pathogenic and commensal protozoans are the causal agents of diarrhea via a school-based cross-sectional survey conducted in Indonesia, in September 2016.

Results: Molecular screening for intestinal protozoans in collected 144 stool samples from healthy students (age range 7-15 years) was carried out.

Molecular phylogeny of Blastocystis isolates from wild rodents captured in Indonesia and Japan.

Blastocystis sp. is a common intestinal protist found worldwide in a variety of animals, including humans. Currently, 17 subtypes (STs) of Blastocystis isolates from mammalian and avian host species have been reported based on the small subunit ribosomal RNA gene (SSU rDNA).

Blastocystis phylogeny among various isolates from humans to insects.

Blastocystis is a common unicellular eukaryotic parasite found not only in humans, but also in various kinds of animal species worldwide. Since Blastocystis isolates are morphologically indistinguishable, many molecular biological approaches have been applied to classify these isolates. The complete or partial sequences of the small subunit rRNA gene (SSU rDNA) are mainly used for comparisons and phylogenetic analyses among Blastocystis isolates.

Molecular survey of Blastocystis sp. from humans and associated animals in an Indonesian community with poor hygiene.

Blastocystis sp. is a common parasite found in human and animal fecal samples. Currently, human Blastocystis isolates are classified into nine subtypes (STs) based on the phylogeny of their small subunit ribosomal RNA genes (SSU rDNAs).

Human Blastocystis subtyping with subtype-specific primers developed from unique sequences of the SSU rRNA gene.

The genus Blastocystis is one of the most genetically diverse parasites. Blastocystis isolates from humans and animals have been classified into subtypes (STs) based on the phylogeny of the small subunit rRNA gene (SSU rDNA). Although human Blastocystis isolates are limited to STs 1-9, the identification of all 9 STs remains challenging due to the lack of specific primers for several STs.

Prediction of Development of Critical Limb Ischemia in Hemodialysis Patients.

Hemodialysis (HD) patients with critical limb ischemia (CLI) suffer chronic inflammation and repeated infection, require intervention, and may have a protracted hospital stay. Therefore, early prediction is particularly important for management of CLI in patients with suspected peripheral artery disease. The purpose of this study is to develop a simple score for predicting the incidence of CLI in HD patients with suspected peripheral artery disease.

The subjects were 40 patients with aortic stenosis and 40 controls.

Genetic diversity of blastocystis in livestock and zoo animals.

Blastocystis is a common unicellular anaerobic eukaryote that inhabits the large intestine of many animals worldwide, including humans. The finding of Blastocystis in faeces in mammals and birds has led to proposals of zoonotic potential and that these hosts may be the source of many human infections. Blastocystis is, however, a genetically diverse complex of many distinct organisms (termed subtypes; STs), and sampling to date has been limited, both geographically and in the range of hosts studied.

Subvalvular aortic stenosis diagnosed by 3D transesophageal echocardiography.

The patient was a 13-year-old male with chief complaints of exertional chest pain and dyspnea.

Midwall ejection fraction for assessing systolic performance of the hypertrophic left ventricle.

Background: In patients with left ventricular hypertrophy (LVH), LV midwall fractional shortening (FS) is used as a measure of LV systolic performance that is more physiologically appropriate than conventional FS. For evaluation of LV volume and ejection fraction (EF), 2-dimensional (2D) echocardiography is more accurate than M-mode echocardiography. The purpose of this study was to assess systolic performance by midwall EF using 2D speckle tracking echocardiography (STE).

A case of paradoxical embolic ST-segment elevation myocardial infarction triggered by sleep apnea.

This report describes an obese 39-year-old man who experienced ST-segment elevation myocardial infarction with total thrombotic occlusion of the right coronary artery. Culprit vessel flow was improved by aspiration. Data suggested that myocardial infarction had resulted from paradoxical embolus via a patent foramen ovale triggered by the Mueller maneuver, which had induced negative intrathoracic pressure following an acute increase of right-heart volume in the context of obesity and sleep-disordered breathing (SDB).

Transcatheter atrial septal defect closure in a patient with paradoxical brain emboli: who should treat it and who should be treated?

This report presents the case of a 51-year-old female who was admitted to a local hospital because of a persistent headache. A diagnosis of multiple cerebral infarctions was thereafter made, but there was no evidence of either atherosclerosis or atrial fibrillation. The case was thought to be a cryptogenic stroke, however, Doppler ultrasonography of the lower extremities showed venous insufficiency.

Impact of cilostazol on left ventricular geometry and function: assessment by tissue Doppler imaging and two-dimensional speckle-tracking echocardiography.

Objectives: Cilostazol, a type III phosphodiesterase inhibitor, is an antiplatelet agent with vasodilating properties.
