This systematic review and meta-analysis included randomized controlled trials or observational studies that compare digital health interventions (DHIs) for telemedicine/telehealth versus usual care for managing blood pressure (BP) in adults. We searched PubMed, Cochrane CENTRAL, and IchuShi-Web, and used a random-effects meta-analysis of the weighted mean difference (MD) between the comparison groups to pool data from the included studies. The outcome included the pooled MD of office BP from baseline to each follow-up period.

The combination effects of smoking (SMK) and hyperuricemia (HU) on renal arteriolosclerosis in patients with IgA nephropathy remain unknown. We examined the cross-sectional association between smoking (current or former) and renal arteriolar hyalinosis and wall thickening with or without HU [uric acid (UA) level ≥ 7 and ≥5 mg/dL in men and women] in 87 patients with IgA nephropathy who underwent renal biopsy. Arteriolar hyalinosis and wall thickening were assessed by the semiquantitative grading of arterioles.

Hypertension remains a major global healthcare issue. Considering that most Japanese patients with hypertension are managed by general practitioners, hypertension specialists should be involved in actual clinical practice. We investigated the blood pressure (BP), guidelines recommended for achievement rate of the target BP, and clinical variables of patients with hypertension treated by hypertension specialists and those treated by non-specialists in a real-world setting.

Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) was approved for medical use in 2011 and is currently used as a rapid, accurate and lowcost technique for bacterial identification. External quality control for medical analysis is monitored using tests of the Japanese Association of Medical Technologists and Prefectural Association of Clinical Laboratory Technologists and through user surveys of reagent and equipment manufacturers. However, external quality control of bacterial typing using MS is not performed.

Article Synopsis
  • Autoimmune factor V deficiency (AiFVD) is a rare bleeding disorder caused by inhibitors that target factor V, affecting blood clotting ability.
  • In this case, an 89-year-old man experienced excessive bleeding during a surgical procedure for hemodialysis, which was linked to prolonged clotting times and the presence of factor V inhibitors and autoantibodies.
  • Treatment with oral prednisolone led to improvement in his bleeding symptoms and normalization of his coagulation tests after 34 days, highlighting the importance of diagnosing AiFVD in similar patients undergoing hemodialysis.

Article Synopsis
  • The study investigates the relationship between the renal renin-angiotensin system (RAS) and renal arteriolar remodeling in patients with chronic kidney disease (CKD).
  • It analyzes data from patients who underwent renal biopsy, measuring urinary angiotensinogen levels and the wall/lumen ratio of arterioles to assess the effects of RAS on kidney function.
  • Findings indicate that a higher level of urinary angiotensinogen is significantly linked to increased arteriolar remodeling and a decline in kidney function over time, especially in patients with IgA nephropathy.

Patterns of recurrence after low-dose postoperative radiotherapy for head and neck squamous cell carcinoma.

J Egypt Natl Canc Inst

December 2021

Department of Radiology, Graduate School of Medical Science, University of the Ryukyus, 207 Uehara, Nishihara, Okinawa, 903-0215, Japan.

Background: Postoperative chemoradiotherapy is recommended for patients with head and neck squamous cell carcinoma with positive margins or extracapsular extension at high risk of recurrence. However, high-dose radiotherapy in the head and neck region often causes severe acute and late radiation-related adversities. In our institution, the radiation dose has been relatively lower than that used in Western countries to reduce radiation-related toxicities.

Reducing salt and increasing potassium intake are recommended lifestyle modifications for patients with hypertension. The estimated 24-h urinary salt excretion value from spot urine using Tanaka's formula and the salt check-sheet scores, questionnaire-based scores of salt intake, are practical indices of daily salt intake. However, few studies have evaluated salt intake with these methods in hypertensive outpatients.

Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) was approved for medical use in 2011, and is currently used as a rapid, accurate and low-cost technique for bacterial identification. Microbiological testing and internal accuracy control in Japan are mainly implemented in accordance with the standards of the Clinical and Laboratory Standards Institute (CLSI). However, few facilities perform internal accuracy control of bacterial identification by MALDI-TOF MS.

Effect of Mineralocorticoid Receptor Blockade on Arterial Stiffness and Endothelial Function: A Meta-Analysis of Randomized Trials.

Hypertension

March 2021

Department of Cardiovascular Medicine, Nephrology, and Neurology, Graduate School of Medicine (A.S., T.M., A.I., Y.O.), University of the Ryukyus, Okinawa, Japan.

Although numerous studies have confirmed the beneficial effects of pharmacological therapy for arterial stiffness and endothelial dysfunction, which are predictors/therapeutic targets for cardiovascular diseases, only a few overall quantitative evaluations of MRAs (mineralocorticoid receptor antagonists) exist. We searched PubMed and Cochrane CENTRAL (Cochrane Central Register of Controlled Trials) for randomized trials evaluating MRA effects on arterial stiffness measured by pulse wave velocity (PWV) or augmentation index and endothelial function measured by flow-mediated dilation. Data from the included trials were pooled by using random-effects meta-analysis of the weighted mean difference (MD) between the comparator groups.

Aortic valve stenosis [or aortic stenosis, (AS)] is a risk factor in non-cardiac surgery. Guidelines from the European Heart Association recommended that AS treatment should be applied prior to non-cardiac surgery. Transcatheter aortic valve implantation (TAVI) is a method of minimally invasive AS treatment.

The occurrence of second primary tumor (SPT)following malignancy treatment is common. In patients with head and neck (H&N) cancer, SPTs principally occur in the H&N region, lungs or esophagus. Therefore, patient follow-up after cancer treatment is important in order to detect recurrence, metastasis and new primary tumors.

A novel Gram-negative, aerobic, rod-shaped, non-spore-forming bacterial strain, RYU5, was isolated from a stool sample of an inpatient at a hospital in Okinawa, Japan. The optimal growth temperature of RYU5 was 30 °C. Phylogenetic analysis based on the sequences of housekeeping genes, including the 16S rRNA, rpoB, rpoD and gyrB genes, showed that RYU5 was a member of the Pseudomonas putida group and was located close to Pseudomonas monteilii and P.

Clin Oral Investig

June 2019

Department of Oral and Maxillofacial Functional Rehabilitation, Graduate School of Medicine, University of the Ryukyus, 207 Uehara, Nishihara, Okinawa, 903-0215, Japan.

Background: Our aim was to investigate the disease-free survival in patients with tongue squamous cell carcinoma receiving metronomic neoadjuvant chemotherapy with 5-fluorouracil prodrugs (UFT or S-1) plus bleomycin compared with those who had up-front surgery retrospectively.

Methods: In this retrospective study, 108 patients with stages I to II tongue squamous cell carcinoma who had undergone surgery were divided into the "surgery group" or "neoadjuvant chemotherapy group."

Results: A total of 41 patients received up-front surgery; 67 received metronomic neoadjuvant chemotherapy with UFT plus bleomycin (39) or S-1 plus bleomycin (28).

Second primary cancer (SPC) is an important prognostic factor for patients with head and neck cancer (HNC); therefore, the association between the prognosis and development of SPC has been well-reported. The use of 2-[F]-fluoro-2-deoxy-D-glucose-positron emission tomography (FDG-PET) is valuable to examine cancer stage, evaluate treatment responses and investigate suspected relapses or metastases. In the present study, the case of a male patient who was diagnosed with three primary cancer types, including well to moderately differentiated squamous cell carcinoma (SCC) of the mandible, axillary cutaneous poorly differentiated SCC and prostate adenocarcinoma, was described.
