Isquemia

BACKGROUND: Ischemia with the non-obstructive coronary artery (INOCA) is an ischemic heart disease that mostly includes coronary microvascular dysfunction and/or epicardial coronary vasospasm due to underlying coronary vascular dysfunction and can be seen more commonly in female patients. The systemic immune-inflammation index (SII, platelet × neutrophil/lymphocyte ratio) is a new marker that predicts adverse clinical outcomes in coronary artery disease (CAD). OBJECTIVE: This study aims to investigate the relationship between INOCA and SII, a new marker associated with inflammation...

Temperature management has been used in patients with acute brain injury resulting from different conditions, such as post-cardiac arrest hypoxic-ischaemic insult, acute ischaemic stroke, and severe traumatic brain injury. However, current evidence offers inconsistent and often contradictory results regarding the clinical benefit of this therapeutic strategy on mortality and functional outcomes. Current guidelines have focused mainly on active prevention and treatment of fever, while therapeutic hypothermia (TH) has fallen into disuse, although doubts persist as to its effectiveness according to the method of application and appropriate patient selection...

Spinal cord ischaemia leading to paraplegia or paraparesis is one of the most devastating complications of aortic surgery. The risk of ischaemia is particularly high in repairs involving both the thoracic and abdominal segments, because in these cases blood flow to the spinal arteries can be interrupted. Multimodal protocols have now been developed to reduce the incidence of this complication, and include measures such as cerebrospinal fluid (CSF) drainage, avoidance of hypotension and anaemia, systemic hypothermia, neuromonitoring, maintaining distal perfusion during proximal clamping of the aorta, and reimplantation of intercostal or lumbar arteries, whenever feasible...

Glomus tumors are a rare benign neoplasm arising from the neuroarterial structure called the glomus body, a specialized arteriovenous shunt involved in temperature regulation. They represent less than 2% of soft tissue tumors and between 1 to 4.5% of hand´s tumors. Even though its first descriptions appeared almost 100 years ago, late and missed diagnoses are common, which leads to terrible suffering. The classic diagnostic triad consists of spontaneous pain, pressure sensation and tenderness, and cold hypersensitivity...

Sneddon's syndrome (SS) manifests through multiple strokes and livedo reticularis. Livedoid vasculopathy (VL) is characterized by a long history of foot and leg ulceration and histopathology indicating a thrombotic process. Arterial retinal branch occlusion is described in a 52-year-old male with VL. He did not present noticeable laboratory abnormalities, such as antiphospholipid antibodies, or a history of strokes. Retinal artery occlusion accompanied by VL could be a variant of Sneddon's syndrome. Optical coherence tomography angiography revealed a reduction in the macula's vascular layers in the asymptomatic eye, indicating localized microvascular changes as an evolving marker in the pathogenesis of SS...

OBJECTIVE:  The serum ischemia modified albumin (IMA), biglycan, and decorin levels of pregnant women who were hospitalized for threatened preterm labor were measured. METHODS:  Fifty-one consecutive pregnant women with a single pregnancy between the 24th and 36th weeks with a diagnosis of threatened preterm labor were included in the present prospective cohort study. RESULTS:  As a result of multivariate logistic regression analysis for predicting preterm delivery within 24 hours, 48 hours, 7 days, 14 days, ≤ 35 gestational weeks, and ≤ 37 gestational weeks after admission, area under the curve (AUC) (95% confidence interval [CI[) values were 0...

BACKGROUND: Central Illustration : Exaggerated Systolic Blood Pressure Increase with Exercise and Myocardial Ischemia on Exercise Stress Echocardiography ESBPRE: exaggerated systolic blood pressure response to exercise; HR: heart rate; SBP: systolic blood pressure. BACKGROUND: The association between exaggerated systolic blood pressure response to exercise (ESBPRE) and myocardial ischemia is controversial and little studied in patients with established or suspected chronic coronary syndrome...

BACKGROUND: Ischaemic stroke may be a major complication of SARS-CoV-2 infection. Studying and characterising the different aetiological subtypes, clinical characteristics, and functional outcomes may be valuable in guiding patient selection for optimal management and treatment. METHODS: Data were collected retrospectively on consecutive patients with COVID-19 who developed acute focal brain ischaemia (between 1 March and 19 April 2020) at a tertiary university hospital in Madrid (Spain)...

BACKGROUND: Several indexes have been developed to define the risk attributable to lipid metabolism with a single value. The total cholesterol/high-density lipoprotein (TC/HDL-C) and low-density lipoprotein/high-density lipoprotein (LDL-C/HDL-C) ratios are the most used. The higher the value of these ratios, the greater the probability of cardiovascular events. OBJECTIVE: To identify whether the TC/HDL-C and LDL-C/HDL-C ratios are early prognostic markers of mortality and major cardiovascular events in patients with ST-elevation acute coronary syndrome...

BACKGROUND: Dexmedetomidine (DEX), a specific α2-adrenergic receptor agonist, is protective against myocardial ischemia/reperfusion injury (MIRI). However, the association between DEX preconditioning-induced cardioprotection and mitophagy suppression remains unclear. OBJECTIVE: Hence, we aimed to investigate whether DEX preconditioning alleviates MIRI by suppressing mitophagy via α2-adrenergic receptor activation. METHOD: Sixty isolated rat hearts were treated with or without DEX before inducing ischemia and reperfusion; an α2-adrenergic receptor antagonist, yohimbine (YOH), was also administered before ischemia, alone or with DEX...

PURPOSE: This study was performed to evaluate the effect of ethanolic extract of Turkish propolis (EEP) on testicular ischemia/reperfusion (I/R) damage in rats in terms of biochemistry and histopathology, for the first time. METHODS: A total of 18 male Sprague-Dawley rats were divided into three groups with six rats in each group: control, torsion/detorsion (T/D), and T/D+EEP (100mg/kg). Testicular torsion was performed by 720° rotating the left testicle in a clockwise direction...

Acute arterial occlusion of the lower limbs is a medical and surgical emergency due to its morbi-mortality. We present the case of a 59-year-old man admitted to the emergency department for acute and diffuse pain in the left lower limb caused by extensive obstructive clots in the arteries of this limb. Since atheromatous cause was unlikely after angioscopy of the lower limbs, a cardiac origin was suspected. Echocardiogram was normal, however, thoracic angiotomography revealed a floating thrombus in the aortic arch...

Bowel obstruction is common in emergency departments. Obstruction is more common in the small bowel than in the large bowel. The most common cause is postsurgical adhesions. Nowadays, bowel obstruction is diagnosed with multidetector computed tomography (MDCT). MDCT studies for suspected bowel obstruction should focus on four points that need to be mentioned in the report: confirming the obstruction, determining whether there is a single transition point or whether the obstruction is found in a closed loop, establishing the cause of the obstruction, and seeking signs of complications...

Mesenteric vein thrombosis (MVT) is a rare condition that can present acutely, subacutely, or chronically. MVT can be isolated or within a splanchnic thrombosis (spleno-porto-mesenteric). Symptomatic cases usually present as nonspecific abdominal pain, with or without signs of intestinal ischemia, and the diagnosis is usually made by imaging test (abdominal CT or MRI) in patients with high clinical suspicion. An early clinical-surgical approach is recommended to screen those patients with warning signs and who benefit from an exploratory laparotomy in addition to anticoagulant treatment, which is the cornerstone of medical treatment...

INTRODUCTION AND OBJECTIVES: Prognosis in ST-elevation myocardial infarction (STEMI) is determined by delay in primary percutaneous coronary intervention (PPCI). The impact of first medical contact (FMC) facility type on reperfusion delays and mortality remains controversial. METHODS: We performed a prospective registry of primary coronary intervention (PCI)-treated STEMI patients (2010-2020) in the Codi Infart STEMI network. We analyzed 1-year all-cause mortality depending on the FMC facility type: emergency medical service (EMS), community hospital (CH), PCI hospital (PCI-H), or primary care center (PCC)...
