ystem called COM-AF was created to predict AFCS, presenting a greater predictive ability than the original ones. Being necessary future prospective validations.

The aim of this study was to examine the action of inhaled nitric oxide in the patients with pulmonary hypertension administered with a face mask before anesthesia induction.

Ten adult patients scheduled for heart surgery with sternotomy were included in this prospective, interventional, single centre study. The inclusion criteria were patients scheduled for heart surgery with sternotomy with cardiopulmonary bypass (CPB), aged >18 years which presents a pulmonary hypertension (PH) (class 2 or 3 according to the Dana Point classification) with systolic pulmonary arterial pressure (PAPS) >40 mmHg diagnosed by preoperative right cardiac catheterization or by transthoracic echocardiography. The exclusion criteria were heart transplant, PH of type 1, 4, 5, according to the Dana Point classification, methemoglobin reductase deficit, incapacity to understand the protocol and sign the consent.

The administration of iNO decrease pulmonary hypertension (P < 0,001 compared to room air; P = 0,01 compared to pure oxygen administration). The iNO administration did not improve arterial blood oxygenation. The hyperoxia, decrease the cardiac index even with right ventricular post charge decrease. The increased blood oxygenation content cause systemic vascular vasoconstriction and decrease the peripheral oxygen extraction showed with VO

linear increase (P < 0,001).

The administration of inhaled nitric oxide with a face mask before anaesthesia induction is safe and effective method to reduce pulmonary hypertension. The oxygen and hyperoxia influences the systemic vascular resistance and peripheral oxygen consumption.

Cardiac implantable electronic devices (CIED) are becoming more common for the management of underlying of cardiac dysrhythmias, and more patients with these devices are presenting for cardiac and noncardiac procedures.

We performed a retrospective, cohort, single-center study at a tertiary teaching medical center, gathering 151 patients with CIED undergoing elective and emergent surgeries for the time period between November 2013 and December 2016. We aimed to determine whether patients with CIED had the device interrogated before surgery as recommended by the Heart Rhythm Society (HRS)/American Society of Anesthesiologists (ASA) consensus, whether this lack of compliance led to delay in the holding area before surgery and determine the presence of intra- or postoperative cardiac events in these patients.

A total of 76% of patients had interrogation of the device before surgery. Emergent cases were not interrogated as much as elective cases preoperatively (43% vs. 18%, respectively; P < 0.05). In tocommendations will lead to enhanced outcomes.

To describe current fluid and vasopressor practices after cardiac surgery in Australia and New Zealand cardiothoracic intensive care units (ICU).

This web-based survey was conducted in cardiothoracic ICUs in Australia and New Zealand.

Intensivists, cardiac surgeons, and anesthetists were contacted to complete the online survey that asked questions regarding first and second choice fluids and vasopressors and the tools and factors that influenced these choices.

There were 96 respondents including 51 intensivists, 27 anesthetists, and 18 cardiac surgeons. Balanced crystalloids were the most preferred fluids (70%) followed by 4% albumin (18%) overall and among intensivists and anesthetists; however, cardiac surgeons (41%) preferred 4% albumin as their first choice. The most preferred second choice was 4% albumin (74%). Among vasopressors, noradrenaline was the preferred first choice (93%) and vasopressin the preferred second choice (80%). 53% initiated blood transfusion at a hemoglobin threshold of 70 g/L. Clinical acumen and mean arterial pressure were the most commonly used modalities in determining the need for fluids.

There is practice variation in preference for fluids used in cardiac surgical patients in Australia and New Zealand; however, balanced crystalloids and 4% albumin were the most popular choices. In contrast, there is broad agreement with the use of noradrenaline and vasopressin as first and second-line vasopressors. These data will inform the design of future studies that aim to investigate hemodynamic management post cardiac surgery.

Cardiopulmonary bypass (CPB) may lead to tissue hypoxia, inflammatory response, and risk for acute kidney injury (AKI). We evaluated the prevalence of AKI and inflammatory response in neonates undergoing heart surgery requiring CPB with or without antegrade cerebral perfusion (ACP).

Forty neonates were enrolled. The patients were divided into two groups depending on the use of ACP. AKI was classified based on the Kidney Disease Improving Global Outcomes (KDIGO) criteria. Inflammatory response was measured using plasma concentrations of interleukins 6 (IL-6) and 10 (IL-10), white blood cell count (WBC), and C-reactive protein (CRP).

Eight patients (20%) experienced AKI five (29%) in the ACP group and three (13%) in the non-ACP group (P = 0.25). Postoperative peak plasma creatinine and urine neutrophil gelatinase-associated lipocalin were significantly higher in the ACP group than in the non-ACP group [46.0 (35.0-60.5) vs 37.5 (33.0-42.5), P = 0.044 and 118.0 (55.4-223.7) vs 29.8 (8.1-109.2), P = 0.02, respectively]. Four patients in the ACP group and one in the non-ACP group required peritoneal dialysis (P = 0.003). Postoperative plasma IL-6, IL-10, and CRP increased significantly in both groups. There were no significant differences between the ACP and non-ACP groups in any of the inflammatory parameters measured.

No significant difference in the AKI occurrence or inflammatory response related to CPB modality could be found. In our study population, inflammation was not the key factor leading to AKI. Due to the limited number of patients, these findings should be interpreted with caution.

Although conventional cardiopulmonary bypass (cCPB) is still the most widely used method in open heart surgery, methods such as retrograde autologous priming (RAP) are increasingly popular in terms of limiting hemodilution. Our hypothesis is that the use of the RAP method in aortic surgery may result in a limitation of hemodilution and a decrease in fHb levels. For this purpose, plasma free hemoglobin (fHb) levels were investigated in adult open aortic arch repair with axillary artery cannulation patients using cCPB and rRAP methods.

In this study, a total of 36 patients undergoing aortic surgery using rRAP and standard cCPB were investigated. Measurements were performed at five time points After induction of anesthesia, 5

minute of CPB, 10

minute of antegrade cerebral perfusion, 30

minute after declamping of aorta, and at sternum closure. Besides hemodynamic variables, arterial blood gas analysis and postoperative variables, patients were assessed for fHb levels.

The rRAP group had a significantly lower increase in fHb levels in T3, T4, and T5 time points, when compared to the cCPB group (p = 0.002, 0.047, 0.009, respectively). There was no significant difference between the rRAP and cCPB groups in other intraoperative, and postoperative variables. Also, it was observed that rRAP did not make a difference in terms of blood and blood product transfusion.

In this study, in patients undergoing aortic surgery, a reduction in the increase of fHb was observed with the rRAP method which is a simple procedure that does not require high cost or advanced technology.

This report presents a rare clinical case which presented with lower limb deep vein thrombosis and found to have colon polyp incidentally detected while evaluating for occult blood positive in stool. Histopathology of the polyp was suggestive of lung primary and on further evaluation PET scan was suggestive of left lung mass with widespread distant metastasis.Paraneoplastic and autoimmune encephalitis (AIE) syndromes describe a range of inflammatory disorders of the brain. "Classic" paraneoplastic encephalitis syndromes occur due to a remote neoplasm and are associated with antibodies that target intracellular neuronal proteins while the more recently described AIE syndromes are not always paraneoplastic and occur in association with antibodies that target cell-surface neuronal receptors (e.g., anti-NMDA receptor, anti-LGI1, anti-GABAB receptor).[1] Diagnosis can be difficult and delayed due to nonspecific clinical, imaging, and laboratory findings, and in those syndromes associated with a neoplasm, the neurologic syndromes often precede the cancer diagnosis. We present a case of a 64-year-old patient diagnosed with anti-GABAB receptor encephalitis that subsequently revealed an underlying small cell lung cancer without a primary lung tumor. This case highlights the clinical challenge in diagnosing immune-mediated encephalitis, its methodical work up, and subsequent management.Based on the pathophysiological characterization of COVID-19, initial studies suggested the use of tocilizumab (TCZ), a recombinant humanized monoclonal antibody of the immunoglobulin G1 class, for management of the cytokine storm witnessed in severe cases. Thus, we decided to present a case series of 18 patients with severe COVID-19 treated with TCZ at our hospital. Our results coincide with the fact that the routine use of TCZ in severe COVID-19 is not robustly supported. We believe that the efficacy and safety of this drug and other related molecules should be validated in large randomized clinical trials.Severe pulmonary hypertension (PH) in obese patients pose a challenge to treat despite advances in medical therapeutics. Current treatment options are limited for patients who are not responding to maximal medical therapy. Vemurafenib order Here, we present a case of multifactorial PH, not responsive to ambrisentan, tadalafil, and treprostinil, even after optimization of cardiac and pulmonary function and had a poor prognosis. She demonstrated weight loss after bariatric surgery, improving her restrictive lung disease, obstructive sleep apnea and PH, and overall functionality. Bariatric surgery may offer a potential therapeutic option, in patients with morbid obesity and PH resistant to maximal medical therapy.
