Background: Psychiatric disorders are associated with altered function of inhibitory neurotransmission within the limbic system, which may be due to the vulnerability of selective neuronal subtypes to challenging environmental conditions, such as stress. In this context, parvalbumin (PVB) positive GABAergic interneurons, which are critically involved in processing complex cognitive tasks, are particularly vulnerable to stress exposure, an effect that may be the consequence of dysregulated redox mechanisms...

BACKGROUND: Paravertebral block (PVB) has been proven to be an efficient way to control postoperative pain in patients who have undergone a thoracotomy. This study aimed to explore whether the utilization of a patient-controlled PVB can provide benefits over intravenous patient-controlled analgesia (PCA) for three-port single-intercostal video-assisted thoracic surgery. METHODS: From May 2015 to December 2016, patients who had solitary pulmonary nodules or spontaneous pneumothorax and underwent single-intercostal video-assisted thoracic surgery were randomly allocated to receive patient-controlled PVB or intravenous PCA...

OBJECTIVE: Clinical evidence comparing paravertebral (PVB) and continuous intercostal nerve (ICB) blocks for pain management post video-assisted thoracic surgery (VATS) is limited. This study confirms the analgesic effect of ICB using two catheters is not inferior to that of PVB under direct vision. METHODS: Fifty patients who underwent VATS lobectomy from July 2015 to March 2016 were prospectively recruited and randomly assigned to PVB and ICB groups. Postoperative pain was assessed using the visual analog scale (VAS)...

Calcium homeostasis plays an important role in development of early afterdepolarizations (EADs) and torsade de pointes (TdP). The role of sodium-calcium exchanger (NCX) inhibition in genesis secondary Ca rise and EADs-TdP is still debated. Dual voltage and intracellular Ca optical mapping were conducted in 6 control and 9 failing rabbit hearts. After baseline electrophysiological and optical mapping studies, E4031 was given to simulate long QT syndrome. ORM-10103 was then administrated to examine the electrophysiological effects on EAD-TdP development...

REVIEW
Seamus Crumley, Stefan Schraag
The use of enhanced recovery after surgery (ERAS), as in other surgical specialties, is an emerging concept in cardio-thoracic surgery but there is still a lack of effective protocols to reduce the burden of surgery on the patient, shorten the period of postoperative recovery, and reduce the likelihood of chronic pain developing. The use of local anaesthetic (LA) techniques, such as thoracic epidural analgesia (TEA) and paravertebral blocks (PVB), as an adjunct to anaesthesia are considered key components, though there is little data for direct comparison of the techniques...

In thoracic surgery, the introduction of video-assisted thoracoscopic techniques has allowed the development of fast-track protocols, with shorter hospital lengths of stay and improved outcomes. The perioperative management needs to be optimized accordingly, with the goal of reducing postoperative complications and speeding recovery times. Premedication performed in the operative room should be wisely administered because often linked to late discharge from the post-anesthesia care unit (PACU). Inhalatory anesthesia, when possible, should be preferred based on protective effects on postoperative lung inflammation...

Background: Premature ventricular beats (PVBs) are early depolarization of the myocardium originating in the ventricle. In case of very frequent PVBs, patients are severely symptomatic with impaired quality of life and are at risk of pre-syncope, syncope, heart failure, and sudden cardiac death particularly in the presence of structural heart disease. Ventricular outflow tracts are the most common sites of origin of idiopathic PVBs especially in patients without structural heart disease...

Here we present two cases of gastrostomy insertion via laparotomy in patients with malignant esophageal disease. Patients were ASA (American Society of Anesthesiologists) physical status III and IV. The patients presented as very high risk for general anesthesia, so we decided to use unilateral left sided paravertebral block (PVB) on four thoracic levels along with contralateral local infiltration at the gastrostomy insertion site. We present two cases, one of them a 57-year-old male ASA III patient scheduled for a gastrostomy procedure due to esophageal cancer with infiltration of the trachea...

Premature ventricular beats (PVBs) in competitive athletes are incidentally found during pre-participation ECG screening. Their clinical significance remains debatable with several studies suggesting they are a benign reflection of athlete's heart, and others proposing they may indicate underlying structural heart disease and heightened risk for sudden cardiac death (SCD). Areas covered: Effective management of athletes with PVBs may best be accomplished using an algorithmic approach for risk stratification with a goal of differentiating benign PVBs from those reflective of underlying cardiomyopathies...

Silica/polypyrrole nanocomposites without dopant (SiO2/PPy) and with oxalate dopant (SiO2/PPyOx) were synthesized using polymerization of pyrrole in the presence of nano SiO2. Synthesized SiO2/PPy and SiO2/PPyOx were characterized by FTIR, SEM, TEM and EDX and their electrical conductivities were determined by CV method through the two-point-electrode without electrolyte. The corrosion protection performance of polyvinylbutyral (PVB) coatings containing SiO2/PPyOx was evaluated and compared with that of pure PVB coatings and of PVB coatings containing SiO2/PPy by electrochemical impedance spectroscopy and adhesion measurement...

Dielectric Spectroscopy (DS) and1 H Fast Field-Cycling (FFC) NMR relaxometry were applied for understanding the dynamic behavior of the amorphous ter-polymer poly(vinyl butyral) (PVB) across the glass transition temperature (Tg = 70 °C by Differential Scanning Calorimetry). Above Tg , main chain segmental motions (α relaxation) were detected and characterized using both DS and FFC NMR relaxometry. The correlation times extracted by the analysis of DS and FFC NMR relaxometry data agreed within a factor of three and showed a Vogel-Fulcher-Tammann temperature dependence, with an associated Tg of 69 °C and a fragility of 155 for PVB glass...

Local anesthetic injected into a wedge-shaped space lateral to the spinal nerves as they emerge from the intervertebral foramina produces somatosensory and sympathetic nerve blockade effective for anesthesia and for managing pain of unilateral origin from the chest and abdomen. Paravertebral blockade (PVB) is versatile and may be applied unilaterally or bilaterally. Unlike thoracic epidural, the PVB technique may be used to avoid contralateral sympathectomy, thereby minimizing hypotension and leading to better preservation of blood pressure...

White matter hyperintensities (WMHs) include periventricular WMH (pvWMH) and deep WMH. When hyperintensities in the basal ganglia or brainstem are included, the collective term is subcortical hyperintensities. Both WMH and medial temporal lobe atrophy (MTA) are risk factors for cognitive decline. This prospective study enrolled participants aged 50-85 years and followed their neuropsychological assessments annually for 2 years to explore the interactive effects of WMH and MTA on longitudinal clinical decline...
