A prospective comparison of implant quality between suture-coated seeds and uncoated seeds in prostate cancer brachytherapy.

Purpose: Displacement minimization of seeds is crucial during surgery in brachytherapy; however, only a few reports have compared the operability of different seeds. TheraStrand-SL is a seed, in which TheraAGX100 is wrapped in polyglactin 910 thread, and intra-prostatic displacement is expected to be reduced compared with that of Thera-AGX100, owing to the complex shape of TheraStrand-SL. We conducted a prospective study on the operability and treatment outcomes of TheraAGX100 and TheraStrand-SL placement by a single operator.

Excessive whole-body exposure to 28 GHz quasi-millimeter wave induces thermoregulation accompanied by a change in skin blood flow proportion in rats.

Introduction: Limited information is available on the biological effects of whole-body exposure to quasi-millimeter waves (qMMW). The aim of the present study was to determine the intensity of exposure to increase body temperature and investigate whether thermoregulation, including changes in skin blood flow, is induced in rats under whole-body exposure to qMMW.

Methods: The backs of conscious rats were extensively exposed to 28 GHz qMMW at absorbed power densities of 0, 122, and 237 W/m for 40 minutes.

Intensity-dependent Temperature Rise Induced by Local Exposure to 26.5 GHz Quasi-Millimeter-Wave in Rat.

Background/aim: The widespread use of fifth-generation 5G millimeter-waves (MMW) generates concern about potential adverse health effects. The latest international guidelines for MMW exposure adopt an absorbed power density (APD) of 200 W/m to avoid a local temperature rise of 5°C in human tissues as an operational adverse health effect threshold. However, because APD is estimated by simulations using human tissue models, it is unknown whether a similar value can be confirmed for living tissues.

Effects of treatment contents on changes in resilience among workers with mood or anxiety disorders: A 3-month longitudinal study.

Aim: The aim of this study was to identify factors that influence changes in resilience among workers with mental health disorders, leading to effective treatment and support.

Methods: Among the new patients at an institution, 81 who were working and had the ICD-10 diagnoses F3 and F4 were included. Resilience was measured at the initial visit and 3 months later using the S-H resilience test.

Sarcopenia and excess visceral fat accumulation negatively affect early urinary function after I-125 low-dose-rate brachytherapy for localized prostate cancer.

Objectives: To evaluate the effects of sarcopenia and excess visceral fat accumulation on early urinary function after I-125 low-dose-rate brachytherapy for prostate cancer.

Methods: We retrospectively reviewed consecutive patients who underwent brachytherapy for prostate cancer. Pre-treatment computed tomography was used to measure skeletal muscle index at the L3 level to assess sarcopenia and visceral fat area at the umbilical level.

Clinical outcomes of iodine-125 low-dose-rate brachytherapy for localized prostate cancer: a single-institution review in Japan.

Purpose: To evaluate the oncological outcomes and genitourinary and gastrointestinal adverse events in acute and late-phases of iodine-125 low-dose-rate brachytherapy for localized prostate cancer.

Material And Methods: We retrospectively evaluated 334 patients treated for localized prostate cancer with low-dose-rate brachytherapy. Bio-chemical relapse-free survival, cause-specific survival, and overall survival were evaluated using Kaplan-Meier method and log-rank test.

Novel 60 GHz Band Spatial Synthetic Exposure Setup to Investigate Biological Effects of 5G and Beyond Wireless Systems on Human Body.

The global spread of 5th generation (5G) wireless systems causes some concern about health effects of millimeter waves (MMW). To investigate biological effects of local exposure to 5G-MMW on human body, a novel 60 GHz band exposure setup was developed, and its performance was validated. A spatial synthetic beam-type exposure setup using two dielectric lens antennas was proposed to achieve high intensity 60 GHz irradiation to the target area of human skin.

The relationship between marital status and multifactorial sleep in Japanese day workers.

Unlabelled: Unmarried people often have disorderly lifestyles, and sleep problems (e.g., insomnia, short sleep duration, social jetlag) are becoming more complex due to the modern 24-h society.

Severe immersion pulmonary edema in a novice elderly scuba diver after heavy alcohol intake.

Background: There are no reports of immersion pulmonary edema induced by excessive alcohol intake. We describe the case of a novice scuba diver who developed apnea due to immersion pulmonary edema during scuba diving after heavy alcohol intake.

Case Presentation: A 71-year-old hypertensive man, without regular antihypertensive therapy, performed diving after excessive alcohol intake (total amount, approximately 253 g) until the night before.

Decompression Illness in Repetitive Breath-Hold Diving: Why Ischemic Lesions Involve the Brain?

Nitrogen (N) accumulation in the blood and tissues can occur due to breath-hold (BH) diving. Post-dive venous gas emboli have been documented in commercial BH divers (Ama) after repetitive dives with short surface intervals. Hence, BH diving can theoretically cause decompression illness (DCI).

Diving-related disorders in commercial breath-hold divers (Ama) of Japan.

Decompression illness (DCI) is well known in compressed-air diving but has been considered anecdotal in breath-hold divers. Nonetheless, reported cases and field studies of the Japanese Ama, commercial or professional breath-hold divers, support DCI as a clinical entity. Clinical characteristics of DCI in Ama divers mainly suggest neurological involvement, especially stroke-like cerebral events with sparing of the spinal cord.

[What is the Best Therapeutic Strategy for Decompression Illness? First Aid Oxygen Inhalation and Hyperbaric Oxygen Therapy].

Decompression illness (DCI), a syndrome following inadequate reduction in environmental pressure, has two forms: decompression sickness and arterial gas embolism after pulmonary barotrauma. Recompression therapy using oxygen, a kind of hyperbaric oxygen therapy, has been considered the gold standard treatment for DCI, although there is no randomized controlled trial evidence for its use. We evaluated the effectiveness of recompression therapy in treating DCI by reviewing the reported therapeutic results of serious DCI, especially neurological disorders.

[New Therapeutic Strategies and Future Issues in Hyperbaric Medicine].

Hyperbaric medicine includes two different medical fields: hyperbaric oxygenation (HBO) as emergency and intensive care, and diving medicine. Recent topics in hyperbaric therapy include radiation oncology and regenerative medicine. Of special interest are clinical studies of radiotherapy after HBO that were conducted at some institutes to evaluate its therapeutic effects for cancer patients.

Longitudinal Changes in Health-related Quality of Life After I Low-dose-rate Brachytherapy for Localized Prostate Cancer.

Background/aim: The factors associated with longitudinal changes in health-related quality of life (HRQOL) are unclear. In this study we aimed to evaluate the longitudinal changes and predictors of HRQOL after I low-dose-rate brachytherapy (LDB) for localised prostate cancer (PCA).

Patients And Methods: We evaluated 180 patients with localised PCA treated with LDB.

Hyperacute brain magnetic resonance imaging of decompression illness in a commercial breath-hold diver.

Decompression illness in breath-hold diving is a rare dysbaric disease mainly characterized by stroke-like neurological disorders. The early use of DWI-MRI combined with ADC map in suspected cases can help in the early diagnosis and treatment.

[Central Nervous System Involvement in Breath-Hold Diving].

Diving accident in breath-hold (BH) divers (Ama) is a stroke-like neurological condition involving the brain. Ama divers are at a risk of ischemic brain injuries which are situated in watershed or terminal zones of cerebral arteries, and/or corticomedullary junctional area of cerebral arteries. The underlying mechanisms of brain damage in BH diving remains to be elucidated.

Remarkable Improvement in Clinical Course and Serum KL-6 Levels after Initiation of High-Dose Inhaled Budesonide in Pulmonary Sarcoidosis.

We present a pulmonary sarcoidosis patient with specific elevation of serum Krebs von den lungen-6 (KL-6) levels, who was successfully treated with inhaled corticosteroids. Pulmonary sarcoidosis was initially identified as a chest radiograph abnormality during a routine medical examination, and subsequently confirmed by a high serum level of soluble interleukin 2 receptor. The patient was started on high-dose inhaled budesonide because of high serum levels of angiotensin-converting enzyme (ACE) and KL-6.
