Retrograde blood flow in the internal jugular veins of humans with hypertension may have implications for cerebral arterial blood flow.

Objectives: To use multi-parametric magnetic resonance imaging (MRI) to test the hypothesis that hypertensives would have higher retrograde venous blood flow (RVBF) in the internal jugular veins (IJV) vs. normotensives, and that this would inversely correlate with arterial inflow and gray matter, white matter, and cerebrospinal fluid volumes.

Methods: Following local institutional review board approval and written consent, a prospective observational 3-T MRI study of 42 hypertensive patients (53 ± 2 years, BMI 28.

The confirmation of treatment effects in Japanese acupuncture.

Background: Japanese acupuncture is gaining international recognition. However, previous research has failed to comprehensively describe the characteristics of Japanese acupuncture by not investigating it within the Japanese clinical environment. This qualitative ethnographic study aimed to identify unique and routine elements of Japanese acupuncture, describe these in detail and examine how they related to treatment principles.

Antihypertensive Treatment Fails to Control Blood Pressure During Exercise.

An exaggerated blood pressure (BP) response to maximal exercise is an independent risk factor for cardiovascular events and mortality. It is unclear whether treating BP to guideline recommended levels could normalize the rise in BP during exercise, which is mediated by the metaboreflex. We aimed to assess the BP response to incremental exercise testing and metaboreflex activation in treated-controlled hypertension (n=16), treated-uncontrolled hypertension (n=16), and untreated hypertension (n=11) and 16 control participants with normal BP (n=16).

Contact Tools in Japanese Acupuncture: An Ethnography of Acupuncture Practitioners in Japan.

This study aimed to identify procedural elements of Japanese acupuncture, describe these elements in detail, and explain them in terms of the key thematic category of treatment principles. Between August 2012 and December 2016, ethnographic fieldwork was conducted in Japan. In total, 38 participants were recruited by chain referral and emergent sampling.

Beliefs and values in Japanese acupuncture: an ethnography of Japanese trained acupuncture practitioners in Japan.

Background: Japanese acupuncture is gaining international recognition. However, previous research has failed to comprehensively describe the characteristics of Japanese acupuncture by not investigating it within the Japanese clinical environment. This study aimed to identify unique and routine elements of Japanese acupuncture, describe these elements in detail, and examine how the current beliefs and attitudes of Japanese acupuncture practitioners related to philosophical concepts in their practice.
