Predictors of overall mortality after endovascular abdominal aortic repair - A single centre study.

OBJECTIVES: A current and ongoing challenge is to reduce patient mortality after endovascular abdominal aortic repair (EVAR). This study aimed to assess the predictors of all-cause mortality after EVAR. METHODS: Data regarding the demographic characteristics, comorbidities, laboratory values, selected anatomical factors, post-EVAR treatment, surveillance and complications of patients who underwent elective EVAR for non-ruptured abdominal aortic aneurysm (AAA) between January 2010 and January 2021 were evaluated. Mortality was assessed until 10 October 2023. Multivariate analyses were performed after adjusting for age, hypertension, diabetes mellitus, dyslipidaemia, sex, smoking, number of lumbar arteries, patency of inferior mesenteric artery (IMA), IMA diameter and reinterventions. RESULTS: This study included 196 patients (183 men and 13 women) with a mean age of 72.4 ± 7.67 years. The overall mortality rate during a mean follow-up period of 5.75 ± 3.1 years was 50.0% (N = 98). The 2-, 5- and 10-year mortality rates were 9.7%, 32.0% and 66.6%, respectively. The mortality rates decreased by 59% in patients with reinterventions (hazard ratio [HR]: 0.41; 95% confidence interval [CI]: 0.23-0.73; p = .002) and by 59% in patients treated with angiotensin-converting enzyme (ACE) inhibitors or angiotensin II receptor blockers (ARBs) (HR: 0.41; 95% CI: 0.26-0.66; p < .001). Chronic anticoagulation was associated with 2.09-fold higher mortality (HR: 2.09; 95% CI: 1.19-3.67; p = .010), and coronary artery disease (CAD) was associated with 1.74-fold higher mortality (HR: 1.74; 95% CI: 1.09-2.78; p = .021). Pre-EVAR AAA diameter and 1-year post-EVAR sac diameter were positively associated with mortality (HR: 1.05; 95% CI: 1.03-1.08; p < .001, and HR: 1.05; 95% CI: 1.03-1.07; p < .001, respectively), that is, an increase of pre-EVAR and/or 1-year post-EVAR AAA diameter by 1 mm was associated with a 5% higher risk of all-cause mortality. CONCLUSIONS: Reinterventions and treatment with ACE inhibitors or ARBs may be associated with decreased post-EVAR mortality. A greater pre-EVAR, a post-EVAR AAA diameter, CAD and chronic anticoagulation were associated with higher all-cause mortality post-EVAR.

Deciphering the enigmatic symptoms of Pancoast tumors: Navigating the complex landscape of pain management-A case report.

Pancoast tumors, also known as superior sulcus tumors, encompass a diverse spectrum of neoplasms that infiltrate the apex of the chest wall, yielding distinctive clinical presentations. One of the earliest signs of tumor growth is pain radiating to the upper limb, stemming from peripheral nerve involvement, which can mimic joint pain or spinal radicular irritation. In this case report, we present the clinical history of a 64-year-old female smoker who had previously been recommended for orthopedic elbow surgery due to epicondylitis. Subsequent to the development of additional symptoms and rigorous investigation, a Pancoast tumor was diagnosed. Furthermore, we discuss the characteristic treatment modalities available for Pancoast tumors, including pharmacological pain management and interventional strategies such as spinal cordotomy and spinal alcoholysis. This case underscores the significance of recognizing atypical presentations and emphasizes the importance of comprehensive evaluation in the diagnosis and management of Pancoast tumors.

Endoscopic discectomy of the herniated intervertebral disc and changes in quality-of-life EQ-5D-5L analysis.

Herniated lumbar discs are a common cause of low back pain, which can negatively impact the quality of life of working-age individuals. This study aimed to evaluate changes in the quality of life in patients with sciatica who underwent endoscopic discectomy, a minimally invasive surgical procedure. The study (ClinicalTrials.gov NCT02742311) included 470 patients who underwent transforaminal, interlaminar, or translaminar endoscopic discectomy. Quality of life and pain perception were evaluated by comparing statistically weighted values of EQ-5D-5L, EQ-VAS, Oswestry disability index, and numerical pain scales for lower limb and back pain before and 12 months after the endoscopic procedure. After the procedure, there was a significant improvement in the reduction of back and lower limb pain, as well as in all monitored questionnaires (P < .001), which persisted 12 months after the endoscopy. All evaluated dimensions of the EQ-5D-5L questionnaire indicated a significant improvement in the assessed quality of life (P < .001). The study showed that percutaneous endoscopic lumbar discectomy is an effective pain-treating intervention that can improve the quality of life. There was no observed difference in the percentage of complications or re-herniations when comparing the transforaminal and interlaminar, approaches.

Glutathione-Related Enzymes and Proteins: A Review.

The tripeptide glutathione is found in all eukaryotic cells, and due to the compartmentalization of biochemical processes, its synthesis takes place exclusively in the cytosol. At the same time, its functions depend on its transport to/from organelles and interorgan transport, in which the liver plays a central role. Glutathione is determined as a marker of the redox state in many diseases, aging processes, and cell death resulting from its properties and reactivity. It also uses other enzymes and proteins, which enables it to engage and regulate various cell functions. This paper approximates the role of these systems in redox and detoxification reactions such as conjugation reactions of glutathione-S-transferases, glyoxylases, reduction of peroxides through thiol peroxidases (glutathione peroxidases, peroxiredoxins) and thiol-disulfide exchange reactions catalyzed by glutaredoxins.

Full recovery of lung tissue after severe viral pneumonia H1N1: A case report with 10 years follow-up.

RATIONALE: World healthcare frequently faced severe viral pneumonia cases in the last decades, due to pandemic situations such as H1N1, MERS-CoV, and SARS-COVID-19. PATIENT CONCERNS: The impact of viral infection on lung structure, lung function, and overall mortality was significant. The quality of life and assumed life expectancy was decreased with the supposed development of lung fibrosis in involved survived patients. DIAGNOSES: We described the course and treatment of severe pneumonia H1N1 in a 30-year-old patient. INTERVENTIONS: Patient was included in a study regarding the therapeutic efficacy of selenium ClinicalTrials.gov ID: NCT02026856 with 10 years follow-up with concurrently documented X-ray lung examinations and final histology of lung tissue after sudden death. OUTCOMES: All sequential examinations and histological findings show a healing trend with the final full recovery of lung tissue.

Radiofrequency denervation and cryoablation of the lumbar zygapophysial joints in the treatment of positive lumbar facet joint syndrome - a report of three cases.

Radiofrequency denervation of the zygapophysial (facet) joints is a frequently performed procedure for chronic low back pain. However, cryoablation represents a novel therapeutic approach for this condition. We observed and analyzed 3 cases with confirmed positive lumbar facet joint syndrome. Our results show a significant improvement in the clinical state of the patients in the first and third months after the procedure. The 6-month follow-up examination demonstrates a recurrence of pain and a gradual deterioration in the quality of life with a lasting partial pain-relief effect. Thermal radiofrequency denervation and cryoablation of the lumbar zygapophysial joints represent an effective, albeit temporary treatment option for lumbar facet joint syndrome patients, resulting from the pathophysiology of sensory nerve regeneration after destructive procedures. This type of treatment can be used repeatedly in the case of a positive response.

Positive association between calcium channel blocker treatment and persistent type II endoleak.

BACKGROUND: Type II endoleaks are the most common complication occurring after endovascular abdominal aortic aneurysm repair (EVAR). The aims of our study were to evaluate the impact of persistent type II endoleak on sac dynamics post-EVAR, and to study the association between non-anatomical factors including polymorphisms associated with abdominal aortic aneurysm (AAA) and persistent type II endoleak. METHODS: The cohort comprises 210 patients undergoing EVAR between January 2010 and December 2018. A persistent type II endoleak was defined as any type II endoleak lasting longer than six months and included also a type II endoleak diagnosed after six months or more post-EVAR during the 36-month follow-up period confirmed with CT-angiography. Anteroposterior AAA maximum diameter and AAA volume were measured pre-EVAR and 36 months post-EVAR using CT-angiographic pictures. Sac progression was defined as at least 5 mm increase, sac regression as at least 5 mm decrease in the sac diameter in relation to the preprocedural diameter. Sociodemographic information, comorbidities, treatment, laboratory parameters, selected anatomical and genetic factors were all analyzed to determine their impact on persistent type II endoleak. The adjustments included age, hypertension, diabetes mellitus, dyslipidemia, sex, smoking in multivariate analyses. When postprocedural diameter and volume were evaluated, adjustments included also preprocedural diameter/volume. RESULTS: After exclusion, 178 patients with mean age 72.4±7.60 years remained for analysis. Persistent type II endoleak was found in 27.5% of patients (N.=49) and 2.94-times increased risk of sac progression in multivariate analysis (P=0.033). In multivariate analysis, AAA diameter in patients with persistent type II endoleak was 4.31 mm greater than in patients without (B=4.31; P=0.014); and its presence was also associated with 22.0 cm3 greater sac volume (B=22.0; P=0.034) compared to patients without persistent type II endoleak. Treatment with calcium channel blockers increased risk of persistent type II endoleak 2.11-times in multivariate analysis (OR=2.11; 95% CI: 1.05-4.25; P=0.037). No association between persistent type II endoleak and selected polymorphisms associated with AAA and other observed factors were found. CONCLUSIONS: Risk of persistent type II endoleak was more than doubled in patients taking calcium channel blockers. Patients with persistent type II endoleak had greater anteroposterior sac diameter and sac volume compared to patients without persistent type II endoleak.

EQ-5D-5L questionnaire as suitable assessment of quality of life after epiduroscopy : Multicenter randomized double-blind pilot study.

BACKGROUND: Epiduroscopy is a well-established diagnostic and to certain level therapeutic tool in complex situations, where conventional methods such as magnetic resonance imaging (MRI) lack power or resolution to detect pathological changes. Such a situation is primarily failed back surgery syndrome (FBSS) but also radicular pain without surgery. The aim of this study was to determine the effectiveness of epiduroscopic treatment in patients with FBSS. METHODS: A total of 79 patients with FBSS were randomized into 2 groups. The first group underwent epiduroscopy and received mechanical lysis of adhesions only, the second group received also medication into the epidural space (methylprednisolone and hyaluronidase). Patients were subsequently followed for 12 months, with evaluation also after 6 months post-epiduroscopy. Patients were checked in terms of mobility, self-care, usual activities, pain/discomfort and anxiety/depression as defined in the 5­dimensional EQ-5D-5L questionnaire and to asses suitability of this questionnaire in chronic pain states. Data were collected using EQ-5D-5L questionnaire and also quality of life (QoL) questionnaire. RESULTS: In the terms of ability to walk (dimension mobility) and also ability to do housework, study or leisure activities (dimension usual activity) patients improved in both groups after 6 and 12 months after epiduroscopy. In pain dimension there was improvement mainly after 6 months which correlated also with self-care dimension and quality of life self-assessment. Results in anxiety/depression dimension were mixed. CONCLUSION: Epiduroscopy appears to be a beneficial procedure for both patient groups, especially after 6 months, with some benefit remaining after 12 months. The EQ-5D-5L questionnaire seems to be a suitable and comprehensive way to assess patient health in chronic pain states.

A Randomized, Multicenter, Double-Blind, Parallel Pilot Study Assessing the Effect of Mechanical Adhesiolysis vs Adhesiolysis with Corticosteroid and Hyaluronidase Administration into the Epidural Space During Epiduroscopy.

OBJECTIVE: Epiduroscopy is a proven method of diagnosis and treatment for chronic radicular pain after spinal surgery, which is known as failed back surgery syndrome (FBSS). The aim of the study was to compare the efficacy of drugs (the enzyme hyaluronidase and corticosteroid DEPO-Medrol) administrated into the epidural space during epiduroscopy, performed within the ventral and ventro-lateral epidural space with a focus on releasing foraminal adhesions. METHODS: Forty-eight patients with diagnosed FBBS were randomized into two groups before epiduroscopy. Group A received the standard treatment-mechanical lysis of fibrotic tissue in the epidural space. Group B received hyaluronidase and corticosteroid methylprednisolone acetate during the procedure. Subjects were followed for six and 12 months via scheduled double-blinded examinations by pain physicians. Leg and back pain intensity was assessed by an 11-point numerical rating scale, and patients' functional disability was assessed by the Oswestry Disability Index (ODI). RESULTS: Study subjects showed a significant decrease in ODI score in both groups (P < 0.05). Significantly lower pain scores for leg pain (P < 0.05) and back pain (P < 0.05) were also recorded after the six-month follow-up. However, the one-year follow-up showed a return to the baseline ODI values of most monitored pain scores in both groups (P > 0.05). Improvement was only noted on the NRS for back pain at one-year follow-up (P < 0.05). CONCLUSIONS: A significant improvement of leg and back pain was found in both groups after six months. ODI was significantly improved only in group B in both the six- and 12-month intervals. Back pain at one-year follow-up was only improved in group B.

Selenium adjuvant therapy in septic patients selected according to Carrico index.

OBJECTIVES: The objective of this paper is to highlight the selected group of patients in which adjuvant therapy seems to have a more pronounced positive effect. DESIGN AND METHODS: 65 septic patients from the prospective observational study Se-AOX (2008-2012) (ClinicalTrials.gov Identifier: NCT02026856) were divided into a Se group, receiving sodium selenite in a continual infusion of 750µg/24h for 6 days, and a placebo group. They were subsequently divided into subgroups according to the initial Carrico index (CI) on the day of admission: CI>200 and CI<200. Dynamical changes in glutathione peroxidase (GPx), glutathione reductase (GR) and superoxide dismutase activities were recorded at two day intervals. Clinical parameters and mortality were compared. RESULTS: The CI increased in subgroup Se-CI<200 with negative correlation against subgroup Placebo-CI<200 during the last measuring period (p<0.02). GPx activity increased in selenium subgroups with negative correlation against placebo subgroups (p<0.01). SOD activity was elevated in all subgroups in comparison with values of healthy subjects. CONCLUSIONS: Adjuvant selenium therapy seems to be beneficial for a selected group of patients with acute lung injury. However, as is clear from the results discussed, this is not the case with persistent renal failure, as this leads to an inability to maintain synthetic renal function and ensure GPx synthesis.

[Acute multiple organ failure after endoscopic polypectomy]. / Akútne multiorgánové zlyhanie po kolonoskopii s polypektómiou.

BACKGROUND: Serious intraabdominal infections belong among life treating diseases. They are based on spreading infections from focal sources of inflammation in abdomen or damaged intestinal wall. METHODS AND RESULTS: Treatment strategies are surgical intervention, antimicrobial therapy, distributional shock treatment and accurate nutritional support (1). Glutamine and selenium supplementation may improve intestinal functions and restore antioxidant defence (2). Septic shock with multiple organ failure accompanied by serious catabolism and decrease of albumin had developed in a patient after endoscopic polypectomy. Infection source was not discovered by medical imaging examinations non surgical laparotomy. After distributive shock treatment, wide spectral antibiotics and enteral and parenteral nutrition the patients health improved. As adjuvant therapy intravenous supplementation was administered: glutamine in daily dose 2g and sodium selenite in continual infusion in daily dose 750 µg over 6 days. During intensive therapy, inflammatory markers decreased: C-reactive protein, procalcitonin, leukocyte count and neutrophils. Albumin levels increased. CONCLUSIONS: The paper describes therapeutic options during septic shock treatment and reversion possibilities in the catabolic phase of disease.Key words: colonoscopy, septic shock, multiorgan failure, enteral nutrition, parenteral nutrition.
