Article Synopsis
  • An 18-year-old man with refractory cardiogenic shock from dilated cardiomyopathy was treated at the hospital through a paracorporeal left ventricular assist device (LVAD) implantation.
  • Post-surgery, he experienced loss of consciousness and was diagnosed with propionic acidemia after further evaluations revealed metabolic issues and brain imaging findings.
  • Following treatment for both his heart failure and propionic acidemia, his neurological and cardiac functions improved, leading to the successful removal of the LVAD; this case highlights the rare association between propionic acidemia and dilated cardiomyopathy in adults.

Isolated cardiac sarcoidosis (iCS) is increasingly recognized; however, its prognosis and the efficacy of immunosuppressive therapy remain undetermined. We aimed to compare the prognosis of iCS and systemic sarcoidosis including cardiac involvement (sCS) under immunosuppressive therapy.We retrospectively reviewed the clinical data of 42 patients with sCS and 30 patients with iCS diagnosed at Kyushu University Hospital from 2004 through 2022.

Article Synopsis
  • Anemia is common in patients with heart failure, but its effects on those awaiting heart transplants are not well understood; this study evaluates the influence of hemoglobin levels on patient outcomes.
  • The study analyzed 38 heart failure patients listed for transplantation from 2011 to 2022, noting that 66.7% had iron deficiency, with a median hemoglobin of 12.9 g/dL; none died within a year.
  • Results showed that patients with lower hemoglobin had a significantly higher rate of hospitalization for heart failure (40.9% vs 81.9% free of hospitalization), indicating that hemoglobin levels can predict hospitalization risk in these patients.

Purpose: Vitreous humor (VH) is used for postmortem biochemical studies because it is well protected in an uncontaminated state even after death. The goal of this research was to investigate electrolyte concentrations in the VH from human eyes with and without a history of vitrectomy surgery.

Methods: We analyzed the sodium (Na), potassium (K), chloride (Cl) and magnesium (Mg) concentrations from 34 VH samples from 34 patients.

Objective: A Mediterranean dietary pattern, sleeping habits, physical activity, and lifestyle appear to affect reproductive health. There are few reports about whether fertility-specific quality of life (QOL) is linked to infertility treatment outcomes. The aim of this study is to investigate when lifestyle factors and fertility-specific QOL are comprehensively considered, which factors influence assisted reproductive technology (ART) outcomes.

A 69-year-old man was hospitalized for heart failure 7 days after coronavirus disease 2019 (COVID-19) mRNA vaccination. Electrocardiography showed ST-segment elevation and echocardiography demonstrated severe left ventricular dysfunction. Venoarterial extracorporeal membrane oxygenation and Impella 5.

Aims: Cardiac rehabilitation (CR) is an evidence-based, secondary preventive strategy that improves mortality and morbidity rates in patients with heart failure (HF). However, the implementation and continuation of CR remains unsatisfactory, particularly for outpatients with physical frailty. This study investigated the efficacy and safety of a comprehensive home-based cardiac rehabilitation (HBCR) programme that combines patient education, exercise guidance, and nutritional guidance using information and communication technology (ICT).

The duration of fever and symptoms after laninamivir octanoate hydrate (laninamivir) inhalation were investigated in the Japanese 2016/17 influenza season and the results were compared with those of the 2011/12 to 2015/16 seasons. A total of 1278 patients were evaluated for the duration of fever and symptoms in the six studied seasons. In the 2016/17 season, the influenza types/subtypes of the patients were 6 A (H1N1)pdm09 (2.

To assess the extent of susceptibility to the four most commonly used neuraminidase inhibitors (NAIs) in the viruses epidemic in the 2016-17 Japanese influenza season, we measured the 50% inhibitory concentration (IC) of these NAIs for influenza virus isolates from patients and compared them with the results from the 2010-11 to 2015-16 seasons. Viral isolation was done with specimens obtained prior to treatment, and the type and subtype was determined by RT-PCR using type- and subtype-specific primers. The IC was determined by a neuraminidase inhibition assay using a fluorescent substrate.

Objective: We investigated the prognostic significance of morning home SBP (MHSBP) and clinic SBP (CSBP) at baseline and during follow-up in on-treatment hypertensive patients.

Methods: In the Home blood pressure measurement with Olmesartan Naive patients to Establish Standard Target blood pressure study, more than 20 000 Japanese hypertensive patients who started treatment with olmesartan were followed for cardiovascular events for 2 years. MHSBP and CSBP measured at baseline and during follow-up were compared in terms of the prognostic significance in predicting cardiovascular events.

When interpreting home blood pressure (BP) measurements in hypertensive patients, differences between clinic and home BP should be noted. To investigate the differences between clinic and morning home BP in hypertensive patients, we analyzed clinic systolic BP (CSBP) and morning home systolic BP (MHSBP) data from the large-scale observational HONEST (Home BP measurement with Olmesartan Naive patients to Establish Standard Target blood pressure) study (n=21 340), using BP measurements obtained before starting olmesartan administration. We generated Bland-Altman plots, with the horizontal axis representing mean CSBP and MHSBP ([CSBP+MHSBP]/2) and the vertical axis representing the difference between CSBP and MHSBP (CSBP-MHSBP).

Intervention of executive function during early childhood is an important research topic. This study examined the effect of a child-friendly intervention program, where children interacted with a doll or a puppet. Children were presented with cognitive shifting tasks before and after an intervention.

Unlabelled: This study aimed to investigate the relationship between on-treatment morning home blood pressure (HBP) and incidence of cardiovascular events using data from the Home Blood Pressure Measurement With Olmesartan Naive Patients to Establish Standard Target Blood Pressure (HONEST) study, a prospective observational study of 21 591 outpatients with essential hypertension (mean age, 64.9 years; women, 50.6%) enrolled between 2009 and 2010 at clinics and hospitals in Japan.

The authors examined the effects of olmesartan-based treatment on clinic systolic blood pressure (CSBP) and morning home systolic blood pressure (HSBP) in 21,340 patients with masked hypertension (MH), white-coat hypertension (WCH), poorly controlled hypertension (PCH), and well-controlled hypertension (CH) using data from the Home Blood Pressure Measurement With Olmesartan Naive Patients to Establish Standard Target Blood Pressure (HONEST) study. MH, WCH, PCH, and CH were defined using CSBP 140 mm Hg and MHSBP 135 mm Hg as cutoff values at baseline. At 16 weeks, the MH, WCH, PCH, and CH groups had changes in CSBP by -1.

Background: Previously, high-performance liquid chromatography (HPLC) equipped with ultraviolet or fluorescence detectors has been used for separation of human mercaptalbumin (HMA) and human non-mercaptalbumin (HNA). However, it is difficult to perform reliable chromatographic analysis due to peak interference of such serum compounds as uric acid and bilirubin. The aim of this study is to explore a selective and simple analytical method for the determination of HMA and HNA.

In previous studies, statistical method using distribution of detergent power and that of resistance of soil against washing was applied to analyze detergency of oily soil and solid particle soil. In this paper, this method was applied to an analysis of detergency of mixed soil. Artificially soiled cloth prepared by aqueous dispersion method was used as a mixed soil sample.

We have studied the effectiveness of surface tension on surfactants risk assessment. gamma(tox) was defined as surface tension at a point where acute aquatic toxicity of a surfactant emerges. Oryzias latipes, Daphnia magna, and Podocopida were used for acute aquatic toxicity test of 7 surfactants and 3 detergents.
