Difficult tracheal intubation remains a critical issue in airway management. While videolaryngoscopy (VL), particularly using hyperangulated blades such as the C-MAC D-Blade, has become the gold standard due to superior glottic visualization compared to direct laryngoscopy (DL), intubation challenges persist. The ProVu™ Video Stylet (PVS) is a novel device that integrates real-time visualization with a guided endotracheal tube system. This is an open-label, randomized, three-arm parallel-group, we evaluated whether the use of PVS in combination with either DL or VL could improve tracheal intubation outcomes in anesthetized patients with anticipated difficult airways, defined by an Arné score ≥ 11. The primary outcome was first-pass intubation success. Secondary outcomes included laryngoscopy and intubation times, number of attempts, need for external airway manipulation, and complications related to difficult intubation. One hundred fourteen patients undergoing elective surgery were randomized into three groups: VL using C-MAC D-Blade alone, PVS with DL, and PVS with VL. First-pass intubation success was significantly higher in both PVS-assisted groups compared to the VL-only group (100

Although the brain itself lacks nociceptors and cannot directly perceive pain, it can generate chronic pain following injuries such as traumatic brain injury (TBI) or ischemic stroke. This phenomenon arises from disruptions in neural connectivity that distort the interpretation of sensory input. According to Bayes' Rule, the brain combines current sensory input with prior experiences to formulate response predictions. When this process is disrupted by TBI, chronic pain may emerge. This review identified 60 relevant studies through systematic keyword searches, with inclusion based on content relevance following abstract screening. The literature underscores the brain's adaptive processes in interpreting sensory stimuli. Disruptions to this adaptability-such as those caused by neuroinflammation, cytokine activation, or cellular injury-may contribute to persistent pain states. TBI-associated chronic pain is often classified as neuropathic and may arise from peripheral or central nerve damage, inflammation-induced injury, or impaired central processing. Pain resulting from central misinterpretation, as described by Bayesian models, frequently falls outside traditional inflammatory or neuropathic patterns and may not correspond with known dermatomal distributions, complicating diagnosis and treatment.

Elderly patients, when they present to the emergency department (ED) or are admitted to the hospital, are at higher risk of adverse outcomes such as higher mortality and longer hospital stays. This is mainly due to their age and their increased fragility. In order to minimize this already increased risk, adequate triage is of foremost importance for fragile geriatric (>75 years old) patients who present to the ED. The admissions of elderly patients from 1 January 2014 to 31 December 2020 were examined, taking into consideration the presence of two different triage systems, a 4-level (4LT) and a 5-level (5LT) triage system. This study analyzes the difference in wait times and under- (UT) and over-triage (OT) in geriatric and general populations with two different triage models. Another outcome of this study was the analysis of the impact of crowding and its variables on the triage system during the COVID-19 pandemic. A total of 423,257 ED presentations were included. An increase in admissions of geriatric, more fragile, and seriously ill individuals was observed, and a progressive increase in crowding was simultaneously detected. Geriatric patients, when presenting to the emergency department, are subject to the problems of UT and OT in both a 4LT system and a 5LT system. Several indicators and variables of crowding increased, with a net increase in throughput and output factors, notably the length of stay (LOS), exit block, boarding, and processing times. This in turn led to an increase in wait times and an increase in UT in the geriatric population. It has indeed been shown that an increase in crowding results in an increased risk of UT, and this is especially true for 4LT compared to 5LT systems. When observing the pandemic period, an increase in admissions of older and more serious patients was observed. However, in the pandemic period, a general reduction in waiting times was observed, as well as an increase in crowding indices and intrahospital mortality. This study demonstrates how introducing a 5LT system enables better flow and patient care in an ED. Avoiding UT of geriatric patients, however, remains a challenge in EDs.

Pregnancy is closely associated with an elevated risk of arrhythmias, constituting the predominant cardiovascular complication during this period. Pregnancy may induce the exacerbation of previously controlled arrhythmias and, in some instances, arrhythmias may present for the first time in pregnancy. The most important proarrhythmic mechanisms during pregnancy are the atrial and ventricular stretching, coupled with increased sympathetic activity. Notably, arrhythmias, particularly those originating in the ventricles, heighten the likelihood of syncope, increasing the potential for sudden cardiac death. The effective management of arrhythmias during the peripartum period requires a comprehensive, multidisciplinary approach from the prepartum to the postpartum period. The administration of antiarrhythmic drugs during pregnancy necessitates meticulous attention to potential alterations in pharmacokinetics attributable to maternal physiological changes, as well as the potential for fetal adverse effects. Electric cardioversion is a safe and effective intervention during pregnancy and should be performed immediately in patients with hemodynamic instability. This review discusses the pathophysiology of arrythmias in pregnancy and their management.

Introduction: Atrial fibrillation (AF) and diabetes mellitus type 2 (DM2) often coexist; however, a small number of patients with DM2 undergoing catheter ablation (CA) of AF have been included in previous studies. The aim of this study was to evaluate safety and efficacy of ablation therapy in DM2 patients with drug refractory AF. Methods and Results: From January 2005 to September 2006, 70 patients with a diagnosis of DM2 and paroxysmal (n = 29) or persistent (n = 41) AF were randomized to receive either pulmonary vein isolation or a new antiarrhythmic drug treatment (ADT) with a 1‐year follow‐up. The primary endpoint was the time to first AF recurrence. By Kaplan‐Meier analysis, at the end of follow‐up, 42.9% of patients in the ADT group and 80% of patients who received a single ablation procedure and were without medications were free of AF (P = 0.001). In the ablation group, a significant improvement in quality‐of‐life (QoL) scores as compared with ADT group was observed. Six patients in the ADT group (17.1%) developed significant adverse drug effects. Hospitalization rate during follow‐up was higher in the ADT group (P = 0.01). The only complication attributable to ablation was one significant access‐site hematoma. Conclusion: In patients with DM2, CA of AF provides significant clinical benefits over the ADT and appears to be a reasonable approach regarding feasibility, effectiveness, and low procedural risk.

Numerous studies have shown a marked increase in the incidence of diabetes mellitus worldwide. Diabetes mellitus is currently considered equivalent to coronary artery disease in terms of prognostic risk stratification, and its high prevalence makes this clinical condition the first cause of end-stage renal disease requiring chronic hemodialysis or kidney transplant. Even if chronic kidney disease remains the ''Cinderella of the cardiovascular profile'', the presence of microalbuminuria is closely related to a high risk of development of coronary artery disease. The same risk factors that impair heart function are also harmful to the kidney, and the common pathophysiological features of the two systems are at the origin of a new subspecialty, cardionephrology. A crucial task of cardiologists and nephrologists is the early identification of high risk patients with concurrent cardiovascular and kidney disease. The utilization of simple screening methods such as assessment of microalbuminuria and glomerular filtration rate by family doctors may help in establishing prevention strategies directed towards cardiovascular risk and progression of kidney disease. In conclusion, early stratification of cardiovascular risk, coupled with primary prevention strategies aimed at the general population, is warranted to obtain a significant reduction of kidney and cardiovascular disease and of the need for chronic hemodialysis treatment. This strategy is safe and cost-effective in comparison with the costs of chronic dialysis of patients affected by chronic kidney disease.

Endothelial damage, with loss of the vascular protective effects of nitric oxide (NO), is an important early step in the development of microvascular and macrovascular complications of diabetes. Endothelial dysfunction is closely associated with diabetic nephropathy in type 1 and 2 diabetes. In this review we will discuss the mechanisms by which hyperglycemia may cause kidney damage and endothelial dysfunction. Hyperglycemia causes microvascular dysfunction, which contributes to the development of end stage renal dise- ase. Determining the role of endothelial abnormalities in the development of diabetic nephropathy is critical to understanding the etiology and patho- genesis of the microvascular complications of diabetes. Endothelial function can be assessed by invasive and noninvasive techniques both in the coronary and peripheral circulation. Endothelial dysfunction is considered a reversible phenomenon; pharmacological intervention with hypolipidemic agents, in- sulin sensitizers, ACE inhibitors and angiotensin II receptor blockers (ARB) as well as dietary and lifestyle modifications have been shown to reverse it.

During the last 50 years, many studies have analysed the correlations between personality factors, behavioural pattern, personality type, psychiatric disorders and coronary artery disease (CAD). Although consistent evidence of causal association between CAD and major depressive disorders does exist, the role and importance of personality factors and character traits in CAD development and manifestations are still debatable. We reported the most important studies from the literature on type A behaviour pattern (TABP), the first correlated to CAD. After the initial enthusiasms, large clinical trials raised doubts about the role of TABP as CAD risk factor. We reported subsequent researches aimed at extracting from TABP components predisposing to atherosclerosis, such as hostility and anger. Finally, we analysed a recent personality type (type D) introduced in 1995 and identified as a negative prognostic factor in CAD patients.
