AT1 Receptor Mediated Hypertensive Response to Ang II in the Nucleus Tractus Solitarii of Normotensive Rats Involves NO Dependent Local GABA Release

Conclusion: Our results suggest that the AT1R mediated hypertensive response to angiotensin II within the NTS in normotensive rats is GABA and NO dependent. Nitric oxide produced within the NTS tonically potentiates local GABA and glutamate release. Introduction The central nervous system network that regulates the level of sympathetic tone and, hence, blood pressure, is located in the brainstem and consists mainly of the rostral ventrolateral medulla (RVLM), the paraventricular nucleus (PVN) of the hypothalamus and the nucleus tractus solitarii (NTS) (Guyenet, 2006). It is well-established that the RVLM, the so-called brainstem ‘pressor area,’ is a key site for the regulation of sympathetic tone and blood pressure (Dupont and Brouwers, 2010). The major source of excitatory sympathetic drive from the RVLM are spinally projecting glutamatergic neurons which receive tonic excitatory signals from other brain areas, including the PVN, and inhibitory signals from the caudal ventrolateral medulla (CVLM) and indirectly from the NTS (Guyenet, 2006). The NTS plays an important role in central cardiovascular regulation and is the principal site for the termination of baroreceptor afferent fibers mediating the inhibitory actions of baroreceptors in the arterial wall on sympathetic outflow (Paton and Kasparov, 1999; Guyenet, 2006). Stimulation of mechanosensitive baroreceptors by distension of the arterial wall following blood pressure elevation results in activation ...

This article reviews implications of cannabis use for defendants' eligibility and participation in problem-solving courts, with a focus on adult drug courts and mental health courts. This article also examines a range of policies, such as abstinence-based, tolerance-based, and adaptive approaches, that problem-solving courts may consider implementing. Further research is needed to characterize existing problem-solving court policies toward cannabis use and to develop evidence-based practices that courts may follow.

Conclusion: Emergency SBE under general anesthesia achieves higher diagnosis and detection rates, and fewer adverse events under conscious sedation, when compared to nonemergency SBE, regardless of the route. For patients with overt bleeding, it is easier to find lesions by emergency SBE within 24 hours. PMID: 31534450 [PubMed]

Int J Endocrinol. 2019;2019:5893028 Authors: Zhou L, Kang L, Xiao X, Jia L, Zhang Q, Deng M Abstract The prevalence of diabetes mellitus (DM) has been increasing dramatically worldwide, but the pathogenesis is still unknown. A growing amount of evidence suggests that an abnormal developmental environment in early life increases the risk of developing metabolic diseases in adult life, which is referred to as the "metabolic memory" and the Deve...

Authors: Nakamura H, Utsunomiya A, Ishida Y, Horita T Abstract A 48-year-old man was brought to our emergency room with acute abdominal pain and systemic edema, indicating acute circulatory failure with lactic acidosis. Furosemide treatment paradoxically worsened the systemic edema and induced confusion. He had no drinking history but hardly ate legumes or meats containing thiamine. Administration of fursultiamine dramatically improved the symptoms and subsequently caused pulmonary edema. Thiamine deficiency may occur in nondrinkers with an unbalanced diet. In this condition, diuretic therapy can worsen the symptom...

We describe the case of a patient with myelofibrosis (MF)-associated PH who developed left ventricular dysfunction after five years of treatment with the JAK 1/2 inhibitor, ruxolitinib. This is the first report with histopathological findings that demonstrate possible contradictory effects of a JAK 1/2 inhibitor: improvement of MF-associated PH and cardiotoxicity.

Authors: Hosoda T, Uehara Y, Naito T Abstract Patients with HIV infection represent a high-risk group for medication overdose because of the high frequency of complicating psychiatric disorders. Raltegravir is well-known for its low frequency of adverse effects. We herein report a 42-year-old Japanese man with HIV infection who was hospitalized 6 hours after overdosing with 24,000 mg of raltegravir in a suicide attempt. No serious adverse events occurred, although the plasma concentration of raltegravir at 18 hours after the overdose was 79,871.1 ng/mL. Raltegravir may be well-indicated for HIV patients at risk of ...

We describe the case of a 52-year-old female outpatient who developed OIC while receiving oxycodone for pain due to cancer with multiple bone metastases. Although she did not have brain metastasis, opioid withdrawal syndrome (OWS) developed after taking naldemedine orally. Her Clinical Opiate-Withdrawal Score (COWS) was 19 (moderate symptoms). However, she recovered from OWS on intravenous fentanyl and a continuous infusion of oxycodone. She did not develop OWS thereafter and was discharged two days after recovery.
