Results of infrainguinal revascularization with bypass surgery using a heparin-bonded graft for disabling intermittent claudication due to femoropopliteal occlusive disease.

BACKGROUND: The purpose of this study was to analyze the results of infrainguinal revascularization for disabling intermittent claudication (IC) due to femoropopliteal occlusive disease using bypass graft (BPG) surgery with a heparin-bonded expanded polytetrafluoroethylene (HB-ePTFE) graft. METHODS: Between 2002 and 2016, we performed 1400 BPGs with HB-ePTFE interventions in patients with femoropopliteal occlusive disease, of which IC was an indication in 485 (34.6%) patients. Early major end points were in-hospital mortality and major complications; late major end points were primary patency, freedom from redo bypass, freedom from progression to critical limb ischemia, and freedom from above-knee amputation or prosthetic graft infection. RESULTS: We performed 200 (41.2%) above-knee BPGs and 231 (47.6%) below-knee BPGs; 54 (11.1%) BPGs targeted a tibial artery. In-hospital death occurred in two (0.4%) patients. Overall, the major complication rate was 4.3%. The median duration of follow-up was 33 months (range, 1-150 months; interquartile range [IQR], 14-62.8 months); the cumulative follow-up index for survival was 0.75 ± 0.25. During the follow-up, 56 (11.6%) patients died. Estimated primary patency of the BPG was 86.1% ± 1.6% (95% confidence interval [CI], 82.7-88.9) at 12 months, 68.4% ± 2.4% (95% CI, 63.5-72.9) at 36 months, and 57.7% ± 2.9% (95% CI, 52.0-63.2) at 60 months. On multivariate analysis, runoff status (no or one vessel), site of the distal anastomosis (below the knee), and postoperative medical treatment (oral anticoagulants) impaired primary patency. Estimated freedom from redo bypass was 96.1% ± 0.9% (95% CI, 93.9-97.5) at 12 months, 84.8% ± 1.9% (95% CI, 80.7-88.2) at 36 months, and 76.4% ± 2.6% (95% CI, 71.0-81.1) at 60 months. Both the runoff status (no or one vessel) and the diameter of the graft (6 mm) were significantly associated with the need for redo bypass. Freedom from progression to critical limb ischemia was 86.1% ± 2.2% (95% CI, 81.2-89.9) at 60 months. During the follow-up, there were 20 (4.1%) above-knee amputations, which occurred at a median of 33 months (range, 2-107 months; IQR, 14-63 months) after the indexed BPG intervention. Prosthetic graft infection occurred in seven (1.4%) patients, with a median delay from index procedure to presentation with graft infection of 33 months (range, 1-72 months; IQR, 14-62.5 months), resulting in a freedom from prosthetic graft infection rate of 98.2% ± 2% (95% CI, 95.8-99.2) at 60 months. CONCLUSIONS: In patients suffering from lifestyle-disabling IC with long or complex occlusive lesions of the femoropopliteal segment, open BPG surgery with Hb-ePTFE graft had an acceptably low mortality rate. A poor runoff status was a significant predictor of loss of graft patency, especially after a below-knee anastomosis, as was the need for redo bypass. Dual antiplatelet therapy had significantly better results against follow-up thrombosis, and 8-mm grafts showed better freedom from redo bypass compared with 6-mm grafts.

Prevalence and risk factors for heparin-bonded expanded polytetrafluoroethylene vascular graft infection after infrainguinal femoropopliteal bypasses.

BACKGROUND: To analyze the prevalence and predictors of prosthetic vascular graft infection (PVGI) in a multicenter registry. METHODS: This registry-based, multicenter study retrospectively evaluated PVGI that developed after infrainguinal revascularization performed with a heparin-bonded expanded polytetrafluoroethylene graft that was used in 1400 interventions between 2002 and 2016. A prosthetic graft with infection was defined as direct involvement of the graft with positive bacterial cultures of graft or perigraft material, intraoperative gross purulence or failure of graft incorporation, or exposed graft in an infected wound. RESULTS: Critical limb ischemia (CLI) was the main indication for bypass (n = 915 [65%]). The median duration of follow-up was 29 months (range, 1-168 months; interquartile range, 12-60 months). A total of 33 heparin-bonded expanded polytetrafluoroethylene grafts (2.3%) became infected; the median time to occurrence was 5 months (range, 1-54 months; interquartile range; 2.00-13.25 months). Freedom from PVGI at 1 year was 98% (standard error, 0.4; 95% confidence interval [CI], 97.2-98.9), and 97% (standard error, 0.6; 95% CI, 95.6-98.0) at 5 years. The multivariate model identified CLI (P = .042; hazard ratio, 0.39; 95% CI, 0.164-0.969) to be independently associated with PVGI. In-hospital mortality of PVGI treatment was 12% (n = 4/33). Freedom from major amputation was significantly different between patients with PVGI and those who did not experience this complication (at 1 year, 67.0% vs 88.5%; Log-rank χ2 = 22.5; P = .001). CONCLUSIONS: In our "real-world" multicenter experience the prevalence of PVGI after infrainguinal femoropopliteal bypasses was relatively low at 2.3%, but still associated with significant mortality and limb loss. CLI was the only significant predictor of PVGI. This conclusion is reasonable; however, more comprehensive data are required to confirm these findings, because the presence of ischemic ulcers or gangrene was not predictive of PVGI.

Metacognitive Interpersonal Mindfulness-Based Training for Worry About Interpersonal Events: A Pilot Feasibility and Acceptability Study.

Individuals with personality disorders experience worry and repetitive thoughts regarding interpersonal scenarios. Mainstream mindfulness-based approaches may be insufficient to soothe these individual's distress due to difficulties in letting thoughts go and refocusing attention to the present moment. For this reason, we devised an adapted form of mindfulness-based program called Metacognitive Interpersonal Mindfulness-Based Training (MIMBT) for personality disorders. In this pilot study, 28 individuals attended nine weekly sessions to evaluate the feasibility and acceptability, and to establish preliminary outcomes. All individuals completed the program. Attendance was very high (96%). Significant changes were observed on the primary outcome of reduction in repetitive thinking, measured using the Metacognition Questionnaire-30. We also observed a decrease in depression severity. Despite important limitations, this pilot study suggests that MIMBT has the potential to be a viable and well-accepted option for increasing positive outcomes in the treatment of personality disorders. Clinical considerations and directions for future research are discussed.

Metacognitive Interpersonal Therapy for Treating Persecutory Delusions in Schizophrenia.

MIT aims at progressively fostering metacognition until patients are able to understand what kind of interpersonal events or ideas about self and interpersonal interactions trigger their persecutory delusions and to question the delusional meaning they attribute to events.

Metacognition-oriented social skills training for individuals with long-term schizophrenia: methodology and clinical illustration.

PURPOSE: There is much evidence indicating the presence of social deficits in schizophrenia and the detrimental effect of these deficits on global functioning in this population. As a result, social skills training (SST) has emerged as a legitimate psychosocial treatment, although effectiveness research has revealed small effect sizes and limited generalizability regarding the benefits of this treatment. METHODS: In light of the strong evidence of metacognitive deficits in schizophrenia and the importance of metacognition to successful social functioning, we propose a novel therapeutic intervention wherein metacognitive remediation is integrated into SST: metacognition-oriented social skills training (MOSST). In the current paper, we present MOSST, an adapted SST programme wherein clients are also encouraged to have mindful contact with their own thoughts and to better consider and understand the mental states of others as well as the connection between mental states and behaviour. RESULTS: We present a case wherein an individual with schizophrenia successfully completed the MOSST programme. CONCLUSION: We outline directions for future research, starting with the logical next step of empirically testing the efficacy of MOSST. KEY PRACTITIONER MESSAGE: Currently social skills training is considered to be the elected psychosocial treatment for people affected by schizophrenia, although evidence indicates limited benefits. People with schizophrenia have metacognitive deficits, which interfere with proper social functioning. A metacognitive-oriented social skills training (MOSST) intervention has been developed by the authors.A treatment such as MOSST, which integrates social skills training and metacognitive training, promises to improve social skills through improving the metacognition.

The Effects of Metacognition-Oriented Social Skills Training on Psychosocial Outcome in Schizophrenia-Spectrum Disorders: A Randomized Controlled Trial.

A pilot study of the effects of metacognition-oriented social skills training (MOSST) on social functioning in patients with schizophrenia spectrum disorders (SSDs) reported promising results. The main purpose of the current trial was to compare the effectiveness and potential benefits of MOSST vs conventional social skills training (SST). Single-blind randomized controlled trial with 2 groups of patients aged 18-65 with SSDs on partial hospitalization. Participants were randomly assigned (1:1) to receive 16 group sessions with MOSST or conventional SST, both in addition to standard care, over 4 months, with a 6-month follow-up. Psychosocial functioning, metacognition, and symptom outcomes were measured by blind assessors. Statistical analyses used mixed models to estimate treatment effects in each postrandomization time point. Thirty-six patients were randomly assigned to the MOSST group and 33 patients to the conventional SST group. Between-group differences were significant in favor of MOSST on Social and Occupational Functioning Assessment Scale (SOFAS) and Personal and Social Performance Scale (PSP) total scores at post-treatment and follow-up. Concerning PSP subscales, there were significant between-group differences in favor of MOSST at follow-up on socially useful activities, personal and social relationships, and disturbing and aggressive behaviors. Metacognition only improved following MOSST group. For people with SDDs, MOSST appears to have short- and long-term beneficial effects on social functioning and symptoms. Further studies are required to replicate the current results in other samples.

Laparoscopic omental flap for the treatment of major sternal wound infection after cardiac surgery.

BACKGROUND: The ideal reconstructive procedure after sternal debridement is still a matter of debate. The omentum might be theoretically preferable for its favorable properties, but it is seldom used because it entails the added trauma of a laparotomy. METHODS: Three female patients with severe osteomyelitis after myocardial revascularization underwent sternal debridement and filling of the defect with a laparoscopically prepared omental flap. Sternal wound closure was achieved as a single-stage procedure in 2 patients. The third patient had a poststernotomy septicemia and required a 2-stage procedure. The abdominal procedures were conducted through 3 operating 5-mm ports. Omental flaps were developed by complete separation from the transverse colon and lengthening by division of some anastomosing arteries between gastroepiploic vessels and Barkow's arcade. Thoracic transposition of the omentum was achieved through a 5-cm diaphragmatic incision. The flaps were able to reach the base of the neck and fill the sternal defect in all patients. RESULTS: A smooth postoperative course was observed. Oral intake was started from day 2; sole oral nutrition was maintained from day 3 or 4. Optimal wound healing was observed with minimal or absent local discomfort. Minor transient paradoxical movements of the anterior chest wall disappeared within 1 month. Postoperative hospital stay was 9, 14, and 14 days, respectively. CONCLUSIONS: Laparoscopic omentoplasty, compared with the open procedure, entails several advantages for the treatment of sternal osteomyelitis. The introduction of minimally invasive techniques may widen the indications for the use of the omentum in the treatment of major sternal wound infections.
