RESUMO
BACKGROUND AND AIMS: Sleep disturbances may promote glucose abnormalities and inflammatory burden among shift workers. Therefore, precocious subclinical atherosclerotic process might develop in healthy shift workers even without known metabolic and cardiovascular risk factors. METHODS AND RESULTS: We measured anthropometric parameters, glucose, lipids, inflammation and common carotid Intimal Medial Thickness (cIMT) in rotating-night shift workers (r-NSW, n = 88, age = 40.3 ± 7.8 y) in comparison with former-night shift workers (f-NSW, n = 35, age = 44.2 ± 6.4 y) and with day-only workers (DW, n = 64, age = 44.1 ± 8.9 y). R-NSW and f-NSW showed significantly higher cIMT and high sensitivity C-Reactive Protein (hs-CRP) respect to DW (p = 0.043 and p = 0.025, respectively). IL-1ß levels were higher in r-NSW than in DW and f-NSW (p = 0.043) and significantly correlated with IL6 (r = 0.365, p < 0.001). In addition, r-NSW and f-NSW had higher HbA1c levels in comparison with DW (p = 0.047). Carotid-IMT was significantly related to night shift work (p = 0.023), with age (p < 0.001), with HOMA IR (p = 0.009), with insulin (p = 0.006) with HbA1c (p = 0.002), with LDL cholesterol (p < 0.001), with diastolic BP (p < 0.001), with WBC (p = 0.002) and with IL6 (p = 0.004). After performing a multivariate analysis night shift work remained statistically related to cIMT (B = 2.633, 95%CI = 0.489-4.776, p = 0.016). CONCLUSIONS: Our result described a possible link bridging night shift work, inflammation and carotid Intimal Medial Thickness. Future studies are warranted to understand if carotid atherosclerosis process should be mainly driven by the IL1ß/IL6 citokine axis connected to sleep disturbances.

Ozone therapy is a complementary treatment that has gained popularity due to its safety and wide range of applications. Systemic ozone therapy involves withdrawing 100 to 200 ml of blood, treating it with an oxygen-ozone mixture, and then reinfusing it. This process requires large-caliber venous access, which can be a limitation. To overcome this, alternative administration methods have been explored, including the use of ozonized solutions. The aim of this study is to evaluate the clinical effects of systemic ozone therapy on the perception of quality of life and to analyze the outcomes of different administration methods. Three groups of patients were treated: one group received classical systemic ozone therapy, another received ozone therapy via intravenous infusion of a 5% glucose solution, and the third group alternated between the two methods. The results showed an improvement in perceived quality of life in all groups, regardless of the method used. Thus, systemic ozone therapy showed efficacy in improving the perception of quality of life in our group. Moreover, intravenous infusion of a 5% glucose solution has made it possible to treat patients who could not be treated with the classical method, achieving similar results.
RESUMO
The most commonly studied method of administering ozone therapy is systemic ozone therapy. However, there may be situations where this method is not feasible due to technical issues, such as poor vein condition or anemia. As an alternative method, pre-ozonized solutions, such as 0.9% saline solution, have been investigated for their ease of preparation and administration. However, concerns have been raised regarding the formation of chlorine compounds. Currently, there is no available literature on the treatment potential of pre-ozonized glucose solution. The objective of this study is to compare and evaluate the chemical changes induced by ozonization of a 5% glucose solution and determine if any toxic compounds are produced. Our findings indicate that the chemical alterations following ozone infusion are quantitatively minimal and pose a negligible risk in terms of safety.
RESUMO
Retroperitoneal fibrosis (RPF) is a rare condition characterized by the presence of fibro-inflammatory tissue surrounding the abdominal aorta and iliac arteries, often leading to the involvement of adjacent organs such as the ureters and inferior vena cava. We present a case report of a 56-year-old Caucasian woman with a complex medical history, including Hodgkin's lymphoma treated with chemotherapy and radiotherapy (31 years before), a significant smoking history, and a current presentation of acute kidney injury with oliguria, edema, and hypertension. Initial diagnostic considerations included rapidly progressive glomerulonephritis, supported by clinical and imaging findings. However, the absence of specific autoantibodies and the presence of bilateral calyx-pelvic dilation raised questions regarding alternative diagnoses. Imaging studies, including CT, contrast-enhanced CT, and subsequent MRI, revealed periaortic and paracaval adipose tissue thickening suggestive of periaortitis, leading to a diagnosis of retroperitoneal fibrosis. The multifactorial etiology, including previous radiation therapy, lymphoma history, and significant smoking, posed challenges in establishing a definitive causal link. Despite extensive investigations, including laboratory tests and imaging modalities, no single etiological factor could be conclusively identified. This case underscores the diagnostic complexity of RPF, especially in the presence of multiple potential risk factors, and highlights the importance of considering this condition in the differential diagnosis of patients presenting with renal dysfunction and obstructive uropathy.
RESUMO
A patient with mitochondrial encephalomyopathy, lactic acidosis, and stroke-like episodes (MELAS) syndrome, a rare mitochondrial disease characterized by myopathy, epilepsy, encephalopathy, acidosis, and recurrent cerebral ischemic episodes, underwent systemic hematogenous ozone therapy for 17 years. Despite advancements in the study of mitochondrial diseases, there are currently no available treatments for MELAS. The patient in this case has received over 280 sessions of systemic hematic ozone therapy since 2003 (from the age of 10 years) till the time of publication, without reporting any adverse effects, achieving a normal level of development considering the comorbidities. Possible mechanisms of action of systemic hematogenous ozone therapy include improved efficiency of the mitochondrial oxidative chain through the induction of antioxidant enzymes (catalase, superoxide dismutases {SOD}, peroxidase). More studies are needed to evaluate the actual safety of long-term systemic hematogenous ozone therapy in patients with mitochondrial diseases.
RESUMO
In this article, we present an unusual case of granulomatosis with polyangiitis (GPA) in a 41-year-old man. The initial presentation of the disease was atypical, with persistent fever, cough, and fatigue, accompanied by elevated inflammatory markers in association with a large, solitary lung lesion observed at the chest X-ray. Despite the presence of an initial radiological picture suggesting pneumonia, the lack of response to antibiotics necessitated a more in-depth evaluation. The diagnosis was confirmed through a lung biopsy and serological tests positive for anti-neutrophil cytoplasmic antibodies (c-ANCA). GPA is an anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis, a systemic autoimmune disease characterized by necrotizing granulomatous inflammation and pauci-immune small vessel vasculitis. This case posed diagnostic challenges due to the atypical presentation, initially mistaken for a respiratory tract infection versus cancer. However, the lack of improvement with antibiotics and persistent inflammation raised suspicions of an underlying complex condition. The diagnosis was confirmed through a lung biopsy and positive c-ANCA serological tests. The patient had reported a prior SARS-CoV-2 infection, raising questions about the possible connection between COVID-19 and GPA, as suggested by previous studies. The diagnostic workup ruled out common and rare pulmonary infections, autoimmune diseases, and neoplasms. However, the presence of positive c-ANCA antibodies was pivotal for the GPA diagnosis. Treatment involved the use of high-dose corticosteroids and rituximab to suppress the autoimmune response. Early diagnosis and timely treatment are essential for improving outcomes in patients with GPA.
RESUMO
Despite its beneficial role on insulin resistance and atherosclerosis, adiponectin has been frequently reported as an independent positive predictor of cardiovascular mortality. Very few information is available regarding adiponectin isoforms and mortality, in particular in advanced aging. Baseline serum levels of Total Adiponectin and its circulating isoforms (HMW-, MMW-, LMW-Adiponectin) were measured in 97 old patients (mean age: 79 years). Patients were followed up for all-cause mortality (study end-point) for an average of 76.4 ± 37.3 months. A positive association was observed for LMW-Ad and all-cause mortality (HR: 1.13, 95% CI: 1.05-1,22, p: 0.002). After multivariate adjustment for age, sex and a previous history of myocardial infarction, higher levels of LMW-Ad were significantly associated with all-cause mortality (HR: 1.11, 95% CI: 1.02-1.21; p: 0.017). Interestingly neither total adiponectin neither the other two circulating isoforms (MMW- and HMW-Ad) showed any significant association with the study end-point. Our data suggest that the association between high serum adiponectin levels and increased mortality rate in elderly is contingent to an unbalanced circulating levels of adiponectin isoforms. The present results support the hypothesis that high levels of Low Molecular Weight adiponectin are a biomarker for mortality risk in very old patients.
RESUMO
AIMS: Patients with type 2 diabetes mellitus (T2DM) have an increased risk of fractures, despite having greater bone mineral density (BMD) than non-diabetic subjects. This has led to the hypothesis that the presence of impaired bone quality among diabetics reduces bone strength. The Fracture Risk Assessment Score (FRAX) algorithm, introduced to facilitate the evaluation of fracture risk, underestimates the risk of fracture in diabetic patients. The purpose of this study is to confirm the relationship between the degree of metabolic compensation and the 10-year probability of a major fracture or a hip osteoporotic fracture observed in our previous study and to ascertain whether glycosylated hemoglobin (HbA1c) can improve the predictive value of FRAX in patients with T2DM. METHODS: Our data derive from a retrospective clinical study conducted at the "Tor Vergata" Polyclinic in Rome on 6355 subjects over 50 years of age evaluated for osteoporosis. All available clinical records were examined. HbA1c was available for 242 of these subjects and all had had a Dual-energy X-ray Absorption (DXA) scan of the lumbar spine and femoral neck. The risk of fracture was estimated using the Italian version of the FRAX algorithm. RESULT: Patients with T2DM had BMD and T-scores higher than those of non-diabetic subjects, while FRAX average values were higher in the non-diabetic group. HbA1c and FRAX are inversely correlated with each other: for each incremental percentage point of HbA1c growth, the FRAX major osteoporotic fracture probability is reduced by 0.915 points and the FRAX hip osteoporotic fracture probability by 1.438 points. The introduction of a correction factor derived from HbA1c, resulted in mean FRAX values of diabetic patients equivalent to those of non-diabetic subjects. CONCLUSIONS: We propose a correction factor derived from HbA1c that could enhance the predictive ability of fracture risk estimated by the FRAX algorithm in subjects with T2DM.
