Oncolytic virotherapy (OVT) is a promising anti-tumor modality that utilizes oncolytic viruses (OVs) to preferentially attack cancers rather than normal tissues. With the understanding particularly in the characteristics of viruses and tumor cells, numerous innovative OVs have been engineered to conquer cancers, such as Talimogene Laherparepvec (T-VEC) and tasadenoturev (DNX-2401). However, the therapeutic safety and efficacy must be further optimized and balanced to ensure the superior safe and efficient OVT in clinics, and reasonable combination therapy strategies are also important challenges worthy to be explored.
Here we provided a critical review of the development history and status of OVT, emphasizing the mechanisms of enhancing both safety and efficacy. We propose that oncolytic virotherapy has evolved into the fourth generation as tumor immunotherapy. Particularly, to arouse T cells by designing OVs expressing bi-specific T cell activator (BiTA) is a promising strategy of killing two birds with one stone. Amazing combination of therapeutic strategies of OVs and immune cells confers immense potential for managing cancers. Moreover, the attractive preclinical OVT addressed recently, and the OVT in clinical trials were systematically reviewed.
OVs, which are advancing into clinical trials, are being envisioned as the frontier clinical anti-tumor agents coming soon.

A 75 years old man with previous aortic abdominal aneurysm surgery through a transverse laparotomy underwent bilateral internal thoracic artery to coronary artery bypass grafting. He immediately thereafter developed a severe chest and upper abdominal walls ischemia with metabolic acidosis, and finally deep sternum wound infection and upper abdominal wall necrosis. He benefitted from sternal reconstruction and vaccum assisted treatment, with delayed pectus major flap reconstruction. Chest and abdominal wall infarction following bilateral internal thoracic artery (BITA) harvesting is a very rare but life-threatening complication. Caution use of BIMA should be in order in patients with inferior epigastric artery flow impairment.

Numerous coronary revascularization studies have documented superior results associated with bilateral internal thoracic artery grafting compared with single internal thoracic artery grafting. However, concerns about perioperative complications and the technical challenges inherent in bilateral grafting limit its broad utilization. In this video tutorial we show our routine technique for off-pump bilateral internal thoracic artery grafting, and also discuss the experience of our department and the evolving process of how we have performed myocardial revascularization over the past two decades.

OBJECTIVE: The purpose of the present study was to compare survival outcomes in propensity score-matched patients aged 70 years or greater receiving a bilateral internal thoracic artery graft with patients receiving a single internal thoracic artery graft.
METHODS: Among 4083 consecutive patients with isolated coronary artery bypass grafting who underwent operation between January 2001 and December 2018, we identified 1300 patients aged 70 years or greater; of these, 968 received a bilateral internal thoracic artery (bilateral internal thoracic artery group) and 332 received a single internal thoracic artery (single internal thoracic artery group). Propensity score matching was used to reduce the preoperative patient differences. The 10-year survival and postoperative complications were compared between the 2 groups.
RESULTS: A Kaplan-Meier curve at 10 years of follow-up showed that crude survival was significantly superior in patients with bilateral internal thoracic artery grafts than in patients with single internal thoracic artery grafts (67.0% ± 2.5% vs 56.0% ± 3.4%, respectively; P < .016). In the actuarial survival, estimates for propensity score-matched patients with a bilateral internal thoracic artery showed a significantly higher rates of survival than patients with a single internal thoracic artery by the end of follow-up (66.0% ± 5.3% vs 53.0% ± 3.9%, respectively; hazard ratio, 0.64; 95% confidence interval, 0.44-0.94; P = .022, univariable Cox Model and multivariable analysis hazard ratio, 0.66; 95% confidence interval, 0.45-0.97; P = .036 Cox model). Postoperative complications were all similar between the single internal thoracic artery and bilateral internal thoracic artery groups.
CONCLUSIONS: The use of bilateral internal thoracic artery grafting in older patients improves 10-year survival, with similar postoperative morbidity. This surgical technique might have beneficial effects in survival in patients aged more than 70 years. Its use could be considered more frequently.

The 10-year outcome of the Arterial Revascularization Trial (ART) has recently been published. The study is the largest randomized study comparing bilateral internal thoracic artery (BITA) with single internal thoracic artery (SITA) as a grafting strategy for coronary artery bypass. In this review, a critical appraisal of the study has been performed where the result of the trial has been discussed along with the risk of sternal wound infections, the presence of a learning curve, and the influence of volume on outcomes. The influence of BITA grafting on other aspects like influence on hospital stay and quality of life outcomes has also been discussed.

UNASSIGNED: Over the past three decades, there have been a plethora of retrospective observational data and meta-analyses which support the hypothesis of improved clinical outcomes using bilateral internal thoracic arteries (BITA) when compared to saphenous vein grafts (SVGs). However, recently published results have brought this thinking into doubt. We discuss the existing literature on the subject and attempt to clarify the appropriate use of BITA in coronary artery bypass surgery (CABG).
UNASSIGNED: A review of all existing meta-analyses on BITA was conducted to better understand the utility of BITA in CABG. A review of the largest randomized controlled trials on the subject was then compared to the observational data.
UNASSIGNED: In all existing meta-analyses, BITA shows a significant advantage over the use of a single internal thoracic artery (SITA) with SVGs. The two largest randomized controlled trials evaluating BITA failed to show a survival advantage and brought into question the complications associated with BITA.
UNASSIGNED: At present, the use of multiple arterial grafts remains a reasonable choice, particularly in young patients, provided that their use does not increase the operative risk. Further evidence currently being collected may lend a definitive answer in the near future.

Several advances have been made in recent years to improve outcome for patients with coronary artery disease. One of the most debated topics regarding surgical treatment with coronary artery bypass grafting (CABG) is graft selection. This review aims to present the current status and scientific evidence for bilateral internal thoracic artery (BITA) grafting.
Observational studies and pooled analyses suggest that BITA grafting is associated with improved survival. Early results from a large randomized controlled trial report safety and efficacy of the method. The improved survival might be amplified in select groups, but with an increase in sternal wound-related complications. The benefit of BITA grafts seems to remain to an approximate age of 69 years at surgery. CABG with BITA grafts is likely associated with improved long-term survival at a cost of an increase in sternal wound infections. Ten-year results from the Arterial Revascularization Trial are expected in 2018, providing the best evidence regarding the method yet. Early results show it is a safe method in most patient categories considerable for CABG.

BACKGROUND: French Guiana is a French overseas territory with a rich history of migration that has led to a highly intercultural society. Today, its population is one of the youngest in the French territory and is rapidly increasing. Despite a context of cultural revival seeking \"tradition\", a distanced baseline of local practices is still lacking. This work addresses some aspects of the cultural hybridizations in progress in urban areas.
METHODS: Semi directed interviews were conducted with willing participants aged between 18 and 40. Interviews took place in French Guiana\'s two main urban centres: Cayenne and Saint Laurent du Maroni. People were interviewed about the last medicinal plant they used in the preceding year. Due to the high use of plant baths in French Guiana, a focus was made on baths.
CONCLUSIONS: Eighty-three people answered: 43 women and 40 men (mean age of 28.7 years old). In total, 226 remedies were counted in our study, 155 single plant remedies and 71 compound remedies leading to 316 use reports of plants from 16 cultural groups. A surprising number of 108 botanical species were recorded. Eighty-one recipes for baths were also collected. Despite this high citation rate, a rather low proportion of people declare a systematic and regular recourse upon local pharmacopoeia (46%; 38/83). Although many interviewees used plants, far from the majority used them on a regular basis. In practice, 50% of the species (54/108 spp.; 99/316 URs) are non-native but domesticated exotic species, imported from Asia, Europe, Africa or remote parts of America, either during colonization, the slave trade era, or more recently with the latest migrations.
CONCLUSIONS: Although phytotherapy use is often thought to be related to countryside dwellers and older people, medicinal plants seem to play an important role in the lives of urban French Guianese youth. Research shows a large diversity of medicinal species used linked with the great cultural diversity of the Guianese cities. One characteristic of this population is the hybridization process leading to a perpetual renewal of practices, both in terms of species and practice.

OBJECTIVE: Bilateral internal mammary artery (BIMA) grafting is associated with improved survival. However, many surgeons are reluctant to use this technique, owing to the potentially increased risk of sternal infection. The composite T-graft with radial artery (RA) attached end-to-side to the left internal mammary artery (IMA) provides complete arterial revascularization without increased risk of sternal infection. The purpose of this study is to compare outcomes of these 2 strategies.
METHODS: Patients who underwent BIMA grafting using the composite T-graft technique, between 1996 and 2010 (n = 1329), were compared with 389 patients who underwent composite grafting with a single IMA + RA during the same time period.
RESULTS: Patients undergoing single IMA grafting were older, more often women, and more likely to have diabetes, peripheral vascular disease, and COPD, and to need an emergency operation. Congestive heart failure, left main disease, and recent myocardial infarction were more prevalent with bilateral grafting. Propensity-score matching was used to account for differences between groups in preoperative patient characteristics. The 268 matched pairs had similar characteristics. The median follow-up time was 14.19 (95% confidence interval 13.43-14.95) years. Operative mortality and Kaplan-Meier 10-year survival of the 2 matched groups were similar (3.4% vs 3.7%, and 61.6% vs 64%, for the groups treated with BIMA and single IMA, respectively). Cox-adjusted survival was similar (P = .514). Age, chronic renal failure, and performance of <3 bypass grafts were independent predictors of decreased survival.
CONCLUSIONS: This study suggests that long-term outcomes of arterial revascularization with a composite T-graft constructed using left IMA and RA are not inferior to outcomes after BIMA grafting.

OBJECTIVE: Bilateral internal thoracic artery grafting in elderly patients is controversial. We compared the outcome of bilateral internal thoracic artery grafting with that of single internal thoracic artery and saphenous vein and radial artery conduits in these patients.
METHODS: Patients aged 70 years or more who underwent bilateral internal thoracic artery grafting between 1996 and 2008 (n = 1045) were compared with patients who underwent coronary artery bypass grafting with a single internal thoracic artery + saphenous vein graft (n = 582) or a single internal thoracic artery + radial artery (n = 249).
RESULTS: Prevalence of female gender, diabetes, emergency operation, and chronic obstructive pulmonary disease was lower in the bilateral internal thoracic artery grafting group compared with the internal thoracic artery + radial artery and internal thoracic artery + saphenous vein graft groups, whereas congestive heart failure and recent myocardial infarction were more prevalent in the bilateral internal thoracic artery grafting group. Operative mortality and sternal wound infections were not significantly different between groups. The mean follow-up was 8.17 ± 4.45 years. Ten-year survival (Kaplan-Meier) in the internal thoracic artery + saphenous vein graft group was significantly lower than in the bilateral internal thoracic artery grafting and internal thoracic artery + radial artery groups (P < .001). Assignment to the saphenous vein graft group was also associated with decreased adjusted survival (P < .001) compared with the bilateral internal thoracic artery and internal thoracic artery + radial artery groups.
CONCLUSIONS: This study supports the use of arterial grafts in elderly patients undergoing coronary artery bypass grafting.
