Association of Age and Surgical Technique with the Quality of Life of Male Patients Treated for Abdominal Aorta Aneurysms: A Cross-Sectional Study

OBJECTIVES. The achievement of a good health-related quality of life (HRQoL) has become one of the primary objectives of medical–surgical interventions. The objective of this study is to determine the HRQoL of patients who underwent abdominal aortic aneurysm (AAA) surgery and to analyse the influence of age on HRQoL. MATERIALS AND METHODS. This is an observational cross-sectional study with 151 male patients who underwent an operation for AAAs between January 2013 and December 2020 in two hospital centres. HRQoL was assessed with the Spanish version of the 36-Item Short Form Survey (SF-36), starting in the month following the surgical intervention. Statistical analyses were performed using hypothesis tests and multivariate linear regression. RESULTS: The mean age of the patients was 73 years (SD: 7), and the mean interval between surgery and the interview was 37 months (SD: 27). The scores of the Physical Function (p = 0.001), Vitality (p = 0.016), Social Function (p = 0.014), and Mental Health (p = 0.007) dimensions of the SF-36 were significantly lower in the older age groups. In addition, the scores on the Physical Summary Component (p = 0.003) and the Mental Summary Component (p = 0.026) were significantly lower among individuals older than 70 years of age. The HRQoL in patients who underwent operations for AAAs was similar to that reported in the general population of Spain. Patients with an aorto-aortic shunt had better scores on the Physical Function (Beta: 10; p = 0.014) and Mental Health (Beta: 8.12; p = 0.040) dimensions than those who had an aorto-bi-iliac or bifemoral shunt, regardless of the age of the patients at operation. CONCLUSION: Among patients who underwent an operation for an AAA, there was a negative association between the age at operation and scores on the Physical Function, Vitality, Social Function, and Mental Health dimensions of the SF-36. The type of surgical technique influences the evolution of Physical Function and Mental Health scores, regardless of age.

Chronic venous disease patients show increased IRS-4 expression in the great saphenous vein wall

OBJECTIVES

Chronic venous disease (CVeD) is a multifactorial and debilitating condition that has a high prevalence in Western countries and an important associated socioeconomic burden. Varicose veins (VVs) are the most common manifestations of CVeD. Pathologically, many morphological and functional changes have been described in VVs, which most notably affect venous wall integrity. Previous studies have found several molecular alterations that negatively affect normal cell signaling pathways. Insulin receptor substrate (IRS)-4 is a central adaptor protein that is closely related to insulin/insulin-like growth factor-1 signaling upstream, phosphatidylinositol 3-kinase/Akt or mitogen-activated protein kinases downstream, and other proteins. These molecular pathways have been implicated in CVeD pathogenesis. Thus, the aim of our study was to identify the role of IRS-4 in VV tissue.

METHODS

We conducted a histopathological study to analyze IRS-4 protein expression in CVeD patients compared with healthy controls.

RESULTS

Our results demonstrate a significant increase in IRS-4 expression in VV tissue.

CONCLUSIONS

IRS-4 may be implicated in CVeD development and progression. Therefore, IRS-4 could be a potential diagnostic or therapeutic target for patients with this condition.

Understanding Chronic Venous Disease: A Critical Overview of Its Pathophysiology and Medical Management

Chronic venous disease (CVD) is a multifactorial condition affecting an important percentage of the global population. It ranges from mild clinical signs, such as telangiectasias or reticular veins, to severe manifestations, such as venous ulcerations. However, varicose veins (VVs) are the most common manifestation of CVD. The explicit mechanisms of the disease are not well-understood. It seems that genetics and a plethora of environmental agents play an important role in the development and progression of CVD. The exposure to these factors leads to altered hemodynamics of the venous system, described as ambulatory venous hypertension, therefore promoting microcirculatory changes, inflammatory responses, hypoxia, venous wall remodeling, and epigenetic variations, even with important systemic implications. Thus, a proper clinical management of patients with CVD is essential to prevent potential harms of the disease, which also entails a significant loss of the quality of life in these individuals. Hence, the aim of the present review is to collect the current knowledge of CVD, including its epidemiology, etiology, and risk factors, but emphasizing the pathophysiology and medical care of these patients, including clinical manifestations, diagnosis, and treatments. Furthermore, future directions will also be covered in this work in order to provide potential fields to explore in the context of CVD.

Presentation of a large jejunal artery aneurysm: Management and review of the literature

INTRODUCTION

Jejunal artery aneurysms (JAAs) constitute less than 1% of all visceral artery aneurysms. They affect mostly men in their fifth decade. In the last years, the widespread of fine cut fine image techniques has increased the number of JAAs diagnosed incidentally. The first case was reported by Levine in 1944. Since then, only a half of hundred cases have been reported. There is a lack of consensus of management of intact JAAs because of the low number of cases published. We present the largest JAA reported in the English literature up to our knowledge.

PRESENTATION

We report a 49 year-old woman with a 4 × 5 cm. intact jejunal artery aneurysm found incidentally in a CT. It rose from the first jejunal branch of superior mesenteric artery without signs of rupture. She underwent elective surgery and the aneurysm was completely excised.

DISCUSSION

Causes of JAAs include congenital, atherosclerosis or degenerative process. Their rate of rupture depends on location, size and underlying disease and it reaches 10-20% for all visceral artery aneurysms. Risk factors of rupture include pregnancy, hyper-flow situations and connective diseases. Most of cases in the literature presented rupture at the time of diagnosis. JAAs are usually treated following the recommendations for visceral artery aneurysms, so intact JAAs greater than 2 cm. and those causing symptoms should be treated. Treatment includes surgery, embolisation or stent. Surgery is the preferred management for emergency settings.

CONCLUSION

JAAs are extremely rare and constitute only 1% of all visceral aneurysms. They are a life-threatening condition.

Trends in the incidence of lower limb amputation after implementation of a Multidisciplinary Diabetic Foot Unit

BACKGROUNDS AND OBJECTIVE

Incidence of lower extremity amputations (LEA) in the population with and without diabetes mellitus (DM) was assessed after implementation of a Multidisciplinary Diabetic Foot Unit (MDFU) during 2008.

MATERIAL AND METHODS

Non-traumatic LEA were analyzed, and those performed before (2001-2007) and after (2008-2014) introduction of the MDFU were compared. LEA were grouped by age and sex. Their incidence was expressed as a rate per 100,000 population per year, adjusted to the standard European population.

RESULTS

A total of 664 LEA were performed during the 2001-2014 period, 486 (73%) of them in patients with DM. Total LEA incidence was 11.2/10⁵ population in DM versus 3.9/10⁵ in the population without DM. Incidence of major LEA in patients with DM significantly decreased from 6.1/10⁵ population in the 2001-2007 period to 4.5/10⁵ in the 2008-2014 period (p=.03). Joinpoint regression analysis also showed a reduction in the trend of incidence of major LEA in patients with DM, with an annual percentage change of -3.3% [95% CI, -6.2-0.3] (p=.025). No significant differences were found for all other incidences and trends in the diabetic and non-diabetic populations.

CONCLUSIONS

Implementation of a MDFU has been shown to be associated with a significant reduction in major amputation rate in the diabetic population, although the results are not optimal yet. Both results and work at the MDFU should be improved.

Reducing major lower extremity amputations after the introduction of a multidisciplinary team for the diabetic foot

We analyzed the incidence of lower extremity amputations (LEAs) in the 3rd Health Care Area of Madrid before and after the March 2008 introduction of a multidisciplinary team for managing diabetic foot disease. We compared the amputation rates in people with and without diabetes during 2 periods: before (2001-2007) and after (2008-2011) the introduction of a Multidisciplinary Diabetic Foot Unit (MDFU). We also analyzed the trend of the amputation rates by joinpoint regression analysis and measured the annual percentage change (APC). During the study period, 514 nontraumatic LEAs were performed, 374 (73%) in people with diabetes and 140 (27%) in people without the disease. The incidence of LEAs showed a significant reduction in major amputations in people with diabetes, from 6.1 per 100 000 per year (95% confidence interval [CI] = 4.9 to 7.2), in the 2001 to 2007 period, to 4.0 per 100 000 per year (95% CI = 2.6 to 5.5) in the 2008 to 2011 period (P = .020). There were no changes in incidence of minor or total amputations in the diabetic population or in amputations in the nondiabetic population during the study period. Joinpoint regression analysis showed a significant reduction in the incidence of major LEAs in diabetic population with an APC of -6.6% (95% CI = -10.2 to -2.8; P = .003), but there were no other significant changes. This study demonstrates that the introduction of a multidisciplinary team, coordinated by an endocrinologist and a podiatrist, for managing diabetic foot disease is associated with a reduction in the incidence of major amputations in patients with diabetes.

[Reconstruction of thoracolumbar spine instability: clinical and neuroradiological results of a surgical challenge]

INTRODUCTION

Surgical treatment for thoracolumbar union instability represents a challenge, due to the difficult access to this area of the spine, and to the extreme variability of morphological and biomechanical lesions observed.

AIM

To describe the indications and clinical and neuroradiological results obtained with procedures of anterior or combined spinal fusion-instrumentation used for the treatment of instable thoracolumbar lesions.

PATIENTS AND METHODS

17 patients with thoracolumbar instability were treated surgically, being followed-up at least for one year. Causes of instability were classified in three groups: (i) fractures or fracture-luxations (n = 7), (ii) pathologic fractures following tumoral invasion (n = 6) and (iii) infectious or degenerative spondylodiscitis (n = 5). In order to carry out the substitution of the injured vertebral body an anterior approach to the thoracolumbar union was performed in all cases, using a modified technique of thoracophrenolaparotomy in which the diaphragmatic dome was not incised. Depending on the number of columns of Denis damaged, the vertebral corpectomy was followed by either an anterolateral or a combined spinal fusion-instrumentation.

RESULTS

Pain in standing position was eliminated postoperatively in 83%. Neurological deficits were improved in 50% of cases. Surgical mortality was null and transient postoperative complications occurred in 11.7% of patients, but no lung atelectasis or respiratory infections were observed.

CONCLUSIONS

Chronic pain associated to thoracolumbar instability can be treated successfully by substitution of the damaged vertebral body followed by anterior or combined spinal fusion-instrumentation. Thoracophrenolaparotomy without division of the diaphragm is feasible and it reduces the morbidity associated to postoperative respiratory complications.
