Homcology: home chemotherapy delivery in a simultaneous care project for frail advanced cancer patients.

Homcology is a project that represents both an opportunity for patients who may benefit from chemotherapy so far, but present physical and social problems that prevent day-hospital access, and a model of "no-profit" contribution to the Public Health System. Our medical oncology department conducted the project from May 2014 to January 2019. We included frail patients (G-8 < 14), with advanced disease, treated with oral, subcutaneous, or parenteral biological agents, with limitations to day-hospital access, comorbidities, and at least 6-month life expectancy. A multidisciplinary team included three oncologists, four nurses, an anesthetist, a psychologist, and a physiotherapist. Satisfaction was evaluated with FAMCARE scale. A total of 188 patients (median age of 73 years, 38-87) were enrolled. Ninety percent of patients presented with metastatic disease and a median G-8 score of 8.8 (3-13.5). All of them received anticancer treatment and concomitant supportive care; 24 patients received two or more lines of treatment. The median duration of taking care was 175 days (7-1200). A median number of 254 (195-325) nursing and 164 (139-190) medical visits were performed a year, with an average of 1.9 and 1.2 visits a month per patient respectively. The median number of in-line patients was 20 (17-25). Hospitalization occurred in 18% of cases. One-third of them died at home. The others were referred to hospice. Our experience shows that the integration of home cancer treatment and supportive care is effective. Hospitalization rate is lower than data reported in the literature. Results need to be confirmed in prospective pharmacoeconomics studies.

Splenic artery transposition for hepatic arterial reconstruction in a locally advanced pancreatic cancer: a case report and literature review.

OBJECTIVE: During pancreatic surgery for malignancies, hepatic revascularization is needed in case of en bloc resection with hepatic artery involvement. In these cases, the use of the splenic artery is described in the literature, including transposition and interposition techniques. PATIENTS AND METHODS: We report the case of pancreatic cancer resection with involvement of the right hepatic artery, anomalous arising from the superior mesenteric artery, and hepatic revascularization with splenic artery reconstruction. A literature review to analyze the use of splenic artery in hepatic revascularization during pancreatic cancer surgery was performed. RESULTS: A 61-year-old man with a 55-mm hypovascular tumor in the pancreatic head, in wide contact with the right hepatic artery, underwent total pancreatectomy and splenectomy. Right hepatic artery was resected, and the distal part of the splenic artery was transposed to the right hepatic artery with a termino-terminal anastomosis. Histopathological examination revealed R0 resection. CONCLUSIONS: Hepatic revascularization with splenic artery should be considered in patients suitable to extend resectability in pancreatic cancer surgery. A multidisciplinary approach and careful pre-operative planning are essential.

Management of mycotic aorto-iliac aneurysms: a 30-year monocentric experience.

OBJECTIVE: This study aims to analyze the early and late outcomes of our 30-year experience with mycotic aneurysms of the abdominal aorta and iliac arteries. PATIENTS AND METHODS: This retrospective cohort study compared the outcomes of all the patients with mycotic aneurysm, by analyzing prospectively collected data between September 1989 and October 2019 from the Unit of Vascular Surgery of Fondazione Policlinico Universitario Gemelli - IRCCS in Rome, Italy. RESULTS: Twenty-three patients with mycotic aneurysm were included. Twenty-two patients underwent surgery; one patient arrived at the emergency room with unstable clinical conditions and died before being treated. Fourteen cases (60.9%) were located at the infrarenal aorta, while three cases (13.0%) were pararenal aortic aneurysms. Six cases (26.1%) had an iliac arteries localization. Seventeen patients (77.3%) underwent open surgical repair aneurysmectomy with in situ reconstruction, while three cases (13.6%) underwent extra-anatomic revascularization. Three patients (13.6%) underwent the placement of an endoprosthesis, of whom two underwent hybrid procedures, and one EVAR. The latter underwent an early conversion to open repair due to a type I endoleak. The mean length of hospital stay was 35 ± 18.7 days. Five patients (22.7%) died in the immediate postoperative period. In the follow-up of 45.5 ± 41.3 months (range 2-156), we documented six deaths (35.3%), of whom two (11.8%) were aortic-related for a 34.8% overall aortic-related mortality. Eleven patients were alive, with an overall survival of 47.8%. CONCLUSIONS: Mycotic aneurysm is an extremely rare and varied pathology. Open surgical repair showed to be a safe approach because of a complete and aggressive debridement of local infected tissues, with an acceptable long-term mortality rate.

Ticagrelor and preconditioning in patients with stable coronary artery disease (TAPER-S): a randomized pilot clinical trial.

BACKGROUND: Ticagrelor is a reversibly binding, direct-acting, oral, P2Y12 antagonist used for the prevention of atherothrombotic events in patients with coronary artery disease (CAD). Ticagrelor blocks adenosine reuptake through the inhibition of equilibrative nucleoside transporter 1 (ENT-1) on erythrocytes and platelets, thereby facilitating adenosine-induced physiological responses such as an increase in coronary blood flow velocity. Meanwhile, adenosine plays an important role in triggering ischemic preconditioning through the activation of the A1 receptor. Therefore, an increase in ticagrelor-enhanced adenosine bioavailability may confer beneficial effects through mechanisms related to preconditioning activation and improvement of coronary microvascular dysfunction. METHODS: To determine whether ticagrelor can trigger ischemic preconditioning and influence microvascular function, we designed this prospective, open-label, pilot study that enrolled patients with stable multivessel CAD requiring staged, fractional flow reserve (FFR)-guided percutaneous coronary intervention (PCI). Participants will be randomized in 1:1 ratios either to ticagrelor (loading dose (LD) 180 mg, maintenance dose (MD) 90 mg bid) or to clopidogrel (LD 600 mg, MD 75 mg) from 3 to 1 days before the scheduled PCI. The PCI operators will be blinded to the randomization arm. The primary endpoint is the delta (difference) between ST segment elevations (in millimeters, mm) as assessed by intracoronary electrocardiogram (ECG) during the two-step sequential coronary balloon inflation in the culprit vessel. Secondary endpoints are 1) changes in coronary flow reserve (CFR), index of microvascular resistance (IMR), and FFR measured in the culprit vessel and reference vessel at the end of PCI, and 2) angina score during inflations. This study started in 2018 with the aim of enrolling 100 patients. Based on the rate of negative FFR up to 30% and a drop-out rate up to 10%, we expect to detect an absolute difference of 4 mm among the study arms in the mean change of ST elevation following repeated balloon inflations. All study procedures were reviewed and approved by the Ethical Committee of the Catholic University of Sacred Heart. DISCUSSION: Ticagrelor might improve ischemia tolerance and microvascular function compared to clopidogrel, and these effects might translate to better long-term clinical outcomes.

Diabetic foot infections: a comprehensive overview.

Diabetic foot ulcers (DFUs), a micro-vascular complication, are associated with a substantial increase in morbidity and mortality. DFUs are a complicated mixture of neuropathy, peripheral arterial diseases, foot deformities, and infections. Foot infections are frequent and potentially devastating complications. Infection prospers in more than half of all foot ulcers and is the factor that most often leads to lower extremity amputation. The complications of microbial flora span the spectrum from superficial cellulitis to chronic osteomyelitis and gangrenous extremity lower limb amputations. Wounds without confirmed soft tissue or bone infections do not require antibiotic therapy. Mild and moderate infections need empiric therapy covering Gram-positive cocci, while severe infections caused by drug-resistant organisms require broad-spectrum anti-microbials targeting aggressive Gram-negative aerobes and obligate anaerobes.

The potential role of quantitative digital subtraction angiography in evaluating type B chronic aortic dissection during TEVAR: preliminary results.

OBJECTIVE: To evaluate the role of quantitative digital subtraction angiography (Q-DSA) with parametric color coding (PCC) in assessing patients with type B chronic thoracic aortic dissection (TBCAD) during thoracic endovascular aortic repair (TEVAR) procedures. PATIENTS AND METHODS: A total of 11 patients electively treated in our Department for a TBCAD were retrospectively enrolled. All cases were treated with TEVAR for false lumen aneurysm of the thoracic descending aorta. For digital subtraction angiography (DSA) series post-processing, a newly implemented PCC algorithm was used to turn consecutive two-dimensional images into a single color-coded picture (syngo iFLOW, Siemens AG, Forchheim, Germany). In consensus reading, two clinicians experienced in vascular imaging evaluated the DSA series in blinded assessment and compared them to the color-coded images. PCC was assessed for its accuracy in identifying the true and false lumen as well as whether it could provide improved visualization in pre-deployment stent grafting and the final evaluation of treatment. RESULTS: PCC facilitated the visualization of the aortic dissection angioarchitecture in terms of contemporary true and false lumen vision in 81.8% of the cases. In 72.7% of the procedures, Q-DSA was estimated to improve aorta information assessment in terms of false lumen viewing, and it was possible to identify the proximal entry tear position in 45.4% of the cases. After stent graft deployment, in 72.7% of the cases (all 8 patients in which the aortic arch false lumen was visible in pre-treatment), Q-DSA confirmed the absence of early false lumen reperfusion. CONCLUSIONS: Our results indicate that Q-DSA could be useful in the intraprocedural evaluation of patients with aortic dissection during TEVAR procedures without additional x-ray costs and contrast exposure.

Measuring the health status of patients with vascular leg ulcers and the burden for their caregivers.

OBJECTIVES: To assess the health status of patients with leg ulcers and the impact and consequences of such chronic disease on the life of their caregivers. DESIGN: Observational study in a "day care" setting. MATERIAL: Administration of the Short Form-12 questionnaire and of Visual Analogue Scales for pain to patients; of the Family Strain Questionnaire to caregivers. METHODS: Eighty consecutive patients with leg ulcers and their principal caregivers were observed in the period January-August 2006. RESULTS: The emotional burden and problem in social involvement were statistically significantly higher in caregivers for patients with worse SF-12 scores on the physical scale. Values of emotional burden were lower than those observed for cancer patients and for patients in a persistent vegetative state; however, they were higher than those observed for patients with neurological, respiratory, or renal conditions. The score for social involvement was significantly higher for caregivers of patient with vascular leg ulcers compared to other diseases, with the single exception of the persistent vegetative state. CONCLUSIONS: Leg ulcers alter the relationship between family members, and the physical impairment causes significant strain on the caregiver. The improvement of physical health status in patients with leg ulcers may induce a reduction in the emotional burden and an improvement in the social involvement for caregivers.

Pain and quality of life in patients with vascular leg ulcers: an Italian multicentre study.

OBJECTIVE: To assess pain and quality of life in patients with chronic vascular leg ulcers. METHOD: A multicentre cross-sectional study was conducted. A questionnaire to assess quality of life and report the experience of pain was developed. It incorporated the SF-12 questionnaire and a visual analogue scale (VAS) for the assessment of pain during the day, night and at dressing change. RESULTS: A total of 381 patients (233 females, 148 males) were observed from September to November 2006. The patients had venous (52%), ischaemic (11%), mixed aetiology (10%), hypertensive (2%), microangiopatic (2%), diabetic (9%) and other (14%) types of ulcers. Women experienced more pain and had a worse quality of life than men. Venous ulcers had high mean VAS values during the day (44.4) and night (44.9). However, a higher mean value was recorded at dressing change, when it was similar to the mean for vascular ulcers (57.5 versus 56.3). There was a direct correlation between pain and quality of life, which was worse for ulcers with a longer duration and larger area. Ulcers of less than three months' duration had mean VAS values of 38.7, 36.9, 46.8 compared with 53.8, 53.9, 62.9 for ulcers of over 12 months' duration. Mean SF-12 values for the physical component of the questionnaire also showed that patients whose ulcers had a longer duration had a poorer quality of life (35.9) than patients whose ulcers were more recent (40.9). CONCLUSION: Vascular leg ulcers are very painful and result in a poor quality of life, with a direct correlation with both ulcer duration and ulcer area. Pain relief is required, particularly at dressing changes, as is the selection of advanced wound dressings.

Out-of-the-box pelvic surgery including iliopsoas resection for recurrent gynecological malignancies: Does that make sense? A single-institution case-series.

OBJECTIVE: To report morbidity and oncological outcomes in a consecutive series of lateral isolated recurrent gynecological cancer involving the pelvic side wall (PSW) including the iliopsoas muscle. MATERIAL AND METHODS: We retrospectively evaluated a consecutive series between 6/2013 and 12/2015 of lateral isolated recurrent gynecological malignancies treated with a lateral endopelvic resection (LEPR). LEPR was defined as an en-bloc lateral resection of a pelvic tumor with sidewall muscle, and/or bone, and/or major nerve, and/or major vascular structure. Post-surgical complications, quality of life (QoL) and survivals were computed. RESULTS: Seventy-four women with pelvic isolated relapse were admitted for surgery during the study period. Among them, 8 cases (10.8%) showed lateral isolated relapse involving the iliopsoas muscle and were treated with LEPR. R0 resection was achieved in 6/8 patients (75.0%), while the pathologic margins were microscopically and macroscopically positive in 1 patient (12.5%), respectively. There were no perioperative mortalities. Major postoperative complications occurred in 3 patients (37.5%) through peripheral neuropathies, thrombosis of the vascular graft and compartment syndrome of the leg. Median follow-up time was 21 months (range, 12-28). The 2-year overall survival (OS) was 88% improving up to 100% if R0 resection was achieved. In patients with positive pathologic margins (n = 2), the 2-year OS was 50%. All women showed an improved QoL after surgery. CONCLUSION: LEPR with iliopsoas resection can be safely performed in selected cases with lateral isolated gynecological relapse involving the PSW and was associated with improved QoL and prolonged survival when an R0 resection was achieved.

Evaluation of a new imaging software for aortic endograft planning.

OBJECTIVE: The aim of this study was to evaluate a new 3D Workstation workflow (EVAR Assist, Advantage Windows, GE Healthcare, Chalfont, UK) (EA-AW) designed to simplify complex EVAR planning. PATIENTS AND METHODS: All pre-operative computed tomography (CT) scans of patients who underwent repair at our institution of a complex aortic aneurysm using fenestrated endovascular repair (f-EVAR) between January and September 2014, were reviewed. For each patient, imaging analysis (12 measures: aortic diameters and length and "clock position" of visceral artery) was performed on two different workstations: Aquarius (TeraRecon, San Mateo, CA, USA) and EA-AW. According to a standardized protocol, three endovascular surgeons experienced in aortic endograft planning, performed image analyses and data collection independently. We analyzed an internal assessment between observers (on the Aquarius 3DWS) and an external assessment comparing these results with the planning center (PC) data used to custom the fenestrated endograft of the patients enrolled in this study. Finally, we compared both 3DWS data to determine the accuracy and the reproducibility. A p-value < .05 was considered as statistically significant. Complete agreement between operators was defined as 1.0. RESULTS: Intra- and inter-observer variability (interclass correlation coefficients - ICC: 0.81-.091) was very low and confirmed the reliability of our planners. The ICC comparison between EA-AW and Aquarius was excellent (> 0.8 for both), thus confirming the reproducibility and reliability of the new EA-AW application. Aortic and iliac necks diameters and lengths were similarly reported with both workstations. In our study, the mean difference in distance and orientation evaluation of target vessels evaluated by the two workstations was marginal and has no impact on clinical practice in term of device manufacturing. CONCLUSIONS: We showed that complex EVAR planning can be performed with this new dedicated 3D workstation workflow with a good reproducibility.

Fibroblast growth factor 23 serum level in type 2 diabetic italian subjects with peripheral arterial disease and critical limb ischemia.

OBJECTIVE: Fibroblast growth factor 23 (FGF23) was demonstrated to be involved in the occurrence and development of cardiovascular disease (CVD). The aim of this study was to investigate the potential role of FGF23 on presence and severity of peripheral arterial disease (PAD) in type 2 diabetic patients. PATIENTS AND METHODS: In this study, we analyzed FGF23 serum levels in 413 type 2 diabetic patients with PAD and in 598 diabetic controls without lower limbs atherosclerosis. RESULTS: We found that FGF23 median serum levels were significantly higher in patients than in diabetic controls (69.3 (58.8-75.1) pg/mL in PAD and 42.98 (37.1-49.8) pg/mL in subjects without PAD (p < 0.001) and were significantly and independently associated with critical limb ischemia (CLI) [OR, 7.69 (2.64-16.31); p = 0.001]. CONCLUSIONS: We have found, for the first time, that FGF23 could be associated with presence and severity of PAD in Italian patients with type 2 diabetes.

New modalities of ultrasound-based intima-media thickness, arterial stiffness and non-coronary vascular calcifications detection to assess cardiovascular risk.

BACKGROUND: Carotid intima-media thickness (c-IMT), arterial stiffness (AS) and vascular calcification (VC) are now considered important new markers of atherosclerosis and have been associated with increased prevalence of cardiovascular events. An accurate, reproducible and easy detection of these parameters could increase the prognostic value of the traditional cardiovascular risk factors in many subjects at low and intermediate risk. Today, c-IMT and AS can be measured by ultrasound, while cardiac computed tomography is the gold standard to quantify coronary VC, although concern about the reproducibility of the former and the safety of the latter have been raised. Nevertheless, a safe and reliable method to quantify non-coronary (i.e., peripheral) VC has not been detected yet. AIM: To review the most innovative and accurate ultrasound-based modalities of c-IMT and AS detection and to describe a novel UltraSound-Based Carotid, Aortic and Lower limbs Calcification Score (USB-CALCs, simply named CALC), allowing to quantify peripheral calcifications. Finally, to propose a system for cardiovascular risk reclassification derived from the global evaluation of "Quality Intima-Media Thickness", "Quality Arterial Stiffness", and "CALC score" in addition to the Framingham score.

[Evaluation of stress and human potential in the organization of nursing work]. / Valutazione dello stress e del potenziale umano per l'organizzazione del lavoro infermieristico.

Recent specialized literature about nursing highlighted the causal link among stress, burnout and coping processes. The aim of this study was to evaluate the validity of specific instruments designed to select and manage professional nurses. The instruments studied were: Nurse Stress Index (NSI, Harris, 1989), Maslach Burnout Inventory (MBI, Maslach & Jackson, 1986); Coping Inventory for Stressful Situations (CISS, Endler & Parker, 1990); Job Content Questionnaire (JCQ, Karasek, 1986); and Frequency of Self Reinforcement Questionnaire (FSRQ, Heiby, 1982). 100 professional nurses working in an Institute of Care and Research completed the test battery. Data analysis showed a positive correlation among stress, burnout, emotion-oriented coping, psychophysiological overload and self-undervalue. Classification criteria such as age, sex and professional division moreover highlighted significant differences among nurses. The battery resulted reliable and sensitive in discriminating the different problems linked to nursing and in identifying subjects' personal resources.

Post-EVAR aortic neck elongation: is a real phenomenon or a conformational change during the cardiac cycle?

BACKGROUND: Stent-graft migration is a late-term complication of endovascular abdominal aortic aneurysm repair (EVAR). A recent published study suggests that stent graft migration could be explained only by aortic neck elongation, mimicking the appearance of distal stent graft migration. Several studies about the use of dynamic CT Angiography (CTA) in the evaluation of aortic conformation changes during the cardiac cycle demonstrate that axial aortic pulsatility exists. No studies have been carried out to evaluate if a longitudinal aortic pulsatility also exists, that could justify the aortic neck elongation previously reported. AIM: To assess variations in length of proximal neck and infrarenal abdominal aorta in patients selected to undergo EVAR; to assess if longitudinal aortic pulsatility could modify EVAR planning. PATIENTS AND METHODS: 40 patients with Abdominal Aortic Aneurysm (AAA) underwent both static and dynamic ECG-gated 64-CTA (0.625 mm-slice-collimation; 1.25 mm-reconstruction increment). Manual measurements of aortic neck length and infrarenal abdominal aorta were performed on modified coronal images to determine dynamic conformational changes. RESULTS: Significant longitudinal pulsatility was demonstrated within aneurysm neck (19.1 ± 8.6%) and infrarenal abdominal aorta (6.6 ± 1.6%). When compared to dynamic measurements, the endograft previously selected according to static images in terms of fixation, would be potentially changed in 6/40 patients (15%) whereas 4/40 (10%) patients were not eligible for EVAR. CONCLUSIONS: Dynamic ECG-gated CTA may provide information regarding longitudinal pulsatile motion that could change the EVAR planning based on static imaging. Reported post-EVAR elongation of infrarenal aortic neck could be an unreal phenomenon only due to a conformational change during cardiac cycle.

Foot CT perfusion in patients with peripheral arterial occlusive disease (PAOD): a feasibility study.

PURPOSE: To prospectively assess the technical feasibility and reproducibility of quantitative foot perfusion multidetector-row computed tomography (MDCT) in patients with peripheral occlusive artery disease (PAOD) and to evaluate perfusion parameters changes after endovascular treatment. MATERIALS AND METHODS: Institutional review board approval and informed patient consent were obtained. 10 patients older than 65 years (mean 74.1 years, range 66-95 years) with PAOD and who were referred to our department for single-limb endovascular treatment were enrolled prospectively. All patients underwent foot CT perfusion examinations before and within 72 h after endovascular treatment. A 64-row CT lightspeed VCT scanner (GE Medical Systems) was used with acquisition of eight contiguous 5-mm reconstructed sections (60-s acquisition time; 40 mL Iomeprol 400 mgI/mL, @4 mL/s). Data were analyzed by two blinded readers using commercially available software to calculate perfusion parameters. Inter-observer and intra-observer agreement of perfusion CT analysis was assessed using Bland-Altman analyses and intra-class correlation coefficient (ICC). Changes in perfusion parameters after endovascular treatment were assessed using Wilcoxon's test. RESULTS: Good inter-observer and intra-observer agreement was obtained in all patients. Good agreement was obtained for perfusion parameters for the untreated foot and in repeated studies. By comparing perfusion parameters in the treated foot, a significantly shorter mean transit time (MTT) was obtained. CONCLUSIONS: Foot CT perfusion is a feasible and reproducible technique. A significant decrease of MTT between pre- and post-revascularization suggests improved flow in the below-the-knee arteries.
