RESUMO
OBJECTIVES: Subclavian (SC) and transapical (TA) approaches are the main alternatives to the default femoral delivery for transcatheter aortic valve implantation (TAVI). The aim of this study was to compare complications and morbidity/mortality associated with SC and TA in a long-term time frame. METHODS: From January 2007 to July 2015, 1506 patients underwent TAVI surgery in 36 United Kingdom TAVI centers. Primary outcomes were complications according to VARC-2 criteria. The secondary outcome was long-term survival. RESULTS: The enrolled patients were distributed as follows: 1216 in the TA group and 290 in the SC group. There were no differences in the rates of acute myocardial infarction, emergency valve-in-valve, paravalvular leak, balloon post dilatation, cardiac tamponade, stroke, renal replacement therapy, vascular injuries, and 30-day mortality among the groups. Conversely, the rate of permanent pacemaker implantation (p = .02), the procedural time duration (p = .04), and the 12-month mortality (p = .03) was higher in SC than in TA, while in-hospital length of stay was reduced in SC than in TA (p = .01). Up to 8 years, the long-term mortality was not different among groups (p = .77), and no difference in long-term survival between self- versus balloon-expandable devices was found (p = .26). CONCLUSIONS: According to our results, TA provided the best 12-month survival compared to SC, while the long-term survival up to 2900 days is not significantly different between groups, so SC and TA may both represent a safe non-femoral access if femoral is precluded.

BACKGROUND: Heat-and-pepsin-sensitive plant food allergens (PR-10 and profilin) sometimes cause systemic reaction. OBJECTIVE: To detect the risk factors for systemic reactions induced by labile food allergens. METHODS: A retrospective multicenter study was performed on patients with a documented history of systemic allergic reaction to labile plant food allergens and on age-matched controls with a history of oral allergy syndrome (OAS) induced by the same foods. Offending foods, their amount, and state (solid or liquid), and potential cofactors (nonsteroidal anti-inflammatory drugs, protonic pump inhibitors, exercise, alcohol, and fasting) were considered. RESULTS: We studied 89 patients and 81 controls. Sensitization to PR-10 or profilin, IgE to Bet v 1 and/or Bet v 2, and foods causing OAS were similar in the two groups. Twenty patients experienced >1 systemic allergic reaction. Tree nuts, Rosaceae, Apiaceae, and soymilk were the main offending foods. Seventeen (19%) patients were taking a PPI when the systemic reaction occurred (vs 5% in controls; P < .025). The ingestion of the offending food in liquid form (soymilk) was frequent among patients (15%) but unusual among controls (2%; P < .025). Soy milk-induced systemic reactions were independent of PPI treatment. Fasting and excess of allergen, but not NSAID and exercise, were other relevant cofactors for systemic reactions. Systemic reactions occurred without any identifiable cofactor in 39 (44%) cases. CONCLUSION: PR-10- and profilin-induced systemic reactions are facilitated by PPI, ingestion of large amounts of unprocessed foods, and fasting. Soybean beverages represent a risk for PR-10 hypersensitive patients and should be avoided.

OBJECTIVES: To determine whether a permanent pacemaker (PPM) in situ can enhance survival after transcatheter aortic valve implantation (TAVI), in a predominantly inoperable or high risk cohort. BACKGROUND: New conduction disturbances are the most frequent complication of TAVI, often necessitating PPM implantation before hospital discharge. METHODS: We performed an observational cohort analysis of the UK TAVI registry (2007-2015). Primary and secondary endpoints were 30-day post-discharge all-cause mortality and long-term survival, respectively. RESULTS: Of 8,651 procedures, 6,815 complete datasets were analyzed. A PPM at hospital discharge, irrespective of when implantation occurred (PPM 1.68% [22/1309] vs. no PPM 1.47% [81/5506], odds ratio [OR] 1.14, 95% confidence interval [CI] 0.71-1.84; p = .58), or a PPM implanted peri- or post-TAVI only (PPM 1.44% [11/763] vs. no PPM 1.47% [81/5506], OR 0.98 [0.51-1.85]; p = .95) did not significantly reduce the primary endpoint. Patients with a PPM at discharge were older, male, had right bundle branch block at baseline, were more likely to have received a first-generation self-expandable prosthesis and had experienced more peri- and post-procedural complications including bailout valve-in-valve rescue, bleeding and acute kidney injury. A Cox proportional hazards model demonstrated significantly reduced long-term survival in all those with a PPM, irrespective of implantation timing (hazard ratio [HR] 1.14 [1.02-1.26]; p = .019) and those receiving a PPM only at the time of TAVI (HR 1.15 [1.02-1.31]; p = .032). The reasons underlying this observation warrant further investigation. CONCLUSIONS: A PPM did not confer a survival advantage in the first 30 days after hospital discharge following TAVI.

AIMS: Transaortic (TAo) and transapical (TA) implantation can be used in transcatheter aortic valve implantation (TAVI) when the transfemoral (TF) approach is precluded. We compare the safety and efficacy of these alternative techniques. METHODS: From October 2007 to February 2016, TAo and TA patients' data were collected. Propensity score inverse probability of treatment weight (IPTW) method was employed to minimize the impact of no-randomization bias. RESULTS: From our single-center non-TF-TAVI registry, 282 patients were included: 235 (83.3%) underwent TAo and 47 (16.7%) TA. Differences in baseline characteristics were statistically significant in age, sex, risk profile according to logistic-EuroSCORE, and previous cardiac surgery. No difference in hospital morbidity and mortality, but lower stroke-rate in TAo (1.27% vs. 8.5% p < .01) was observed. This was confirmed at logistic regression after IPTW adjustment (odds ratio [OR]: 0.16, 95% CI 0.03-0.71, p = .01), together with reduced risk of the paravalvular leak (PVL) (OR: 0.14, 95% confidence interval [CI]: 0.02-0.81, p = .02). Kaplan-Meier estimates did not demonstrate differences in long-term mortality among access routes (logrank test p = .13). At the IPTW-Cox regression model, long-term mortality was related to New York Heart Association III-IV (hazard ratio [HR]: 2.92, 95% CI: 1.15-7.40, p = .026), chronic renal failure (HR: 3.25; 95% CI: 1.02-10.32 p = .046), previous transient ischemic attack/stroke (HR: 2.29, 95% CI: 1.25-4.20 p = .007). Sapien-3 device resulted to be a protective factor, reducing long-term mortality (HR: 0.18, 95% CI 0.04- 0.90 p = .03). CONCLUSIONS: TAo is safe and feasible in case of contraindication to femoral approach demonstrating comparable midterm outcomes to TA, thus representing a central access alternative, to increase the overall safety of high-risk TAVI procedures.

BACKGROUND: Chronic pain still occurs in 10-12% of patients who undergo surgical groin hernia repair. Considering the high prevalence of this pathology, we performed a single-center prospective study comparing the laparoscopic trans-abdominal pre-peritoneal (TAPP) approach to the standard surgical open technique for primary uncomplicated hernia repair. METHODS: A prospective cohort of 278 patients was extracted from our dataset: 121 received a laparoscopic TAPP approach, and 157 were treated by the Lichtenstein technique in case of inguinal hernia or by the deployment of a polypropylene plug in case of femoral hernia. Both groups were followed-up for 3 years. RESULTS: A significant difference in haematoma/seroma collection was found (P=0.001) among the groups. Wound infection (P=0.001) and pain perception in the perioperative and early post-operative period were significantly reduced in the TAPP group (P=0.0023 and P<0.0021, respectively). Chronic discomfort at 3-year follow-up was higher in the open approach (P=0.0044), while operative time was marginally shorter compared to TAPP (P =0.002). CONCLUSION: The incidence of chronic pain and the overall complication rate were significantly lower with the TAPP approach. Based on our findings, the TAPP approach deserves to be considered as the treatment of choice for uncomplicated single-site primary hernia surgery. Further studies with a larger sample will be needed to confirm these preliminary data.

AIM: Dilatation of the aortic root (AR) after aortic valve surgery associated with ascending aorta replacement (AVS+AAR) is an important concern in long-term follow-up (FU). This study aimed to identify factors that may be associated with this late complication. MATERIAL AND METHODS: Two-hundred-sixteen consecutive patients (150 males and 66 females) who underwent AVS+AAR from June 2009 to April 2018 at a single center were retrospectively analyzed. The mean trans-thoracic echocardiographic (TTE) FU was 44.9 ± 22.2 months. An increase of 10% in AR size compared to the pre-operative baseline was the outcome variable. The Student t-test or chi-square test was used as appropriate. For a survival analysis, a Kaplan-Meier curve was computed and a log-rank p-value was calculated. Cox's regression model was used to assess the predictive value of variables over time. A p-value < 0.05 was significant. RESULTS: No significant differences were observed among patients who underwent aortic valve repair and those who underwent aortic valve replacement (log-rank = 0.917). In patients who underwent valve replacement, AR enlargement was associated with the difference between the diameter of the prosthetic valve and the diameter of the straight vascular prosthesis (OR 0.87, P = 0.024). Based on the difference in diameter between vascular and valve prosthesis, we arbitrarily classified the patients into two groups: a small group (S) (n = 52), in which the difference was ≤ 5 mm, and a large group (L) (n = 34), in which the difference was > 5 mm. Significant AR enlargement was observed in 30.8 % of the S group and 14.7 % of the L group (log-rank = 0.026). A difference of more than 5 mm between the aortic valve prosthesis and the vascular prosthesis protected against AR enlargement in the long-term FU (OR 12.31, P = 0.033), even after adjusting for age and sex (OR 00.32, P = 0.043). CONCLUSION: According to our findings, a difference between the size of the aortic valve prosthesis and the vascular prosthesis of less than or equal to 5 mm was the only factor that increased the risk of AR enlargement after AVS+AAR in long-term FU.

OBJECTIVES: The use of transcatheter aortic valve implantation (TAVI) has expanded as an alternative to aortic valve replacement, and more than 500,000 patients have been treated worldwide since April, 2002. The aim of this study was to compare complications and morbidity/mortality associated with different TAVI approaches as alternatives to a surgical-femoral approach. METHODS: From January 2007 to January 2015, 2,863 patients underwent TAVI surgery in 36 United Kingdom TAVI centers. Primary outcomes were complications according to VARC-2 criteria. The secondary outcome was long-term survival. RESULTS: The enrolled patients were distributed as follows: 1,150 in the surgical-femoral (SF) group, 1,216 in the trans-apical (TA) group, 207 in the direct-aortic (DA) group, and 290 in the subclavian (SC) group. There were no differences in the rates of acute myocardial infarction, emergency valve-in-valve, cardiac tamponade, or TIA among the groups. The rates of stroke and renal replacement therapy, as well as in-hospital stay, in-hospital death, and 30-day and 12-month mortality in DA and TA were higher than those in SC and SF. The rates of paravalvular leak and balloon post-dilatation in SC and DA were higher than those in TA and SF. The rates of vascular injuries and permanent pacemaker implantation in SC and SF were higher than those in DA and TA. SF provided the best long term-survival (p = 0.008). CONCLUSIONS: This was a large study that compared outcomes and long-term survival among different TAVI surgical approaches in a national real-world setting. According to our results, SF provided the best survival. While SC provided worse survival than SF, it was still better than TA and DA, and thus may represent the safest non-femoral access if use of the femoral approach is precluded.

BACKGROUND: The laparoscopic appendectomy approach (LAA) for acute appendicitis has fewer intra- and post-operative complications, less pain, and smaller scars compared to the traditional open appendectomy approach (OAA), but a higher frequency of intra-abdominal abscess (IAA). The relationship between this higher frequency of IAA and the omission of appendicular stump invagination is difficult to explain, even though such invagination of the appendicular stump is the only difference between standard LAA and OAA.

BACKGROUND: Anal fissure is a common proctological condition that is usually defined as an anodermal ulcerative process starting from the posterior commissure to the dentate line. The objective of this study was to evaluate the resolution rate of anal fissure through the use of conservative management in patients grouped according to our newly proposed classification. A secondary purpose was to quantify the recurrence rates at 2-years follow-up in each group. METHODS: A retrospective analysis was carried out on patients in our general database. Diagnosis was based on symptoms, clinical observation, anal manometry and transanal ultrasounds. After application of inclusion and exclusion criteria, patients were assigned to different groups. Follow-up was carried out at 3, 6, 12 and 24 months. RESULTS: A total of 136 patients (54 female and 82 male) were included in the statistical analysis. At the end of the treatment period, all patients in groups 1 and 2 had a complete resolution of illness and a normal basal sphincterial tone, while those in groups 3 and 4 had a higher rate of recurrence at the 2-year follow-up. CONCLUSION: Based on our series, we propose a definitive non-surgical management for all group 1 and 2 anal fissures according to our protocol. For groups 3 and 4, we recommend a primary non-surgical approach with follow-up. This was a retrospective study and further randomized controlled studies will be necessary to confirm our results.

BACKGROUND: Left atrial ablation is a surgical standard technique for the treatment of persistent or chronic atrial fibrillation (p-AF and c-AF, respectively).Objective The aim of the study is to evaluate midterm results of left atrial ablation according to modified Maze procedure in patients affected by p-AF or c-AF and concomitant mitral or aortic valve disease requiring surgical treatment. METHODS: A total of 108 patients (age, mean ± standard deviation [SD]: 66 ± 8.5 years) underwent left atrial ablation by means of unipolar (n = 62) or bipolar (n = 66) radiofrequency for p-AF (n = 28) or c-AF (n = 100) in association with mitral (n = 93) or mitral and aortic valve (n = 35) surgery. RESULTS: In-hospital mortality was 0.8%. Patients with preoperative c-AF had preoperative greater value of left atrial diameter (56.7 ± 7.4 vs. 52 ± 9 mm, p = 0.05) than those with p-AF. At 9 years after Maze procedure, 86% (n = 24/28) of patients with preoperative p-AF were in sinus rhythm versus 28% (n = 27/95) with c-AF (p < 0.0001). Preoperative c-AF and left atrial diameter of 75 mm or more predicted atrial fibrillation recurrence. In patients in sinus rhythm compared with those in residual atrial fibrillation, survival was 100 versus 86% ± 6.4%, New York Heart Association class was 1.3 ± 0.5 versus 1.7 ± 0.6, and need of lifelong anticoagulation therapy was 43 versus 91% (p < 0.05, for all comparisons). CONCLUSIONS: Left atrial Maze procedure for p-AF offers better chances to conversion in sinus rhythm as compared with long-standing c-AF. Survival, functional status, and quality of life are superior in patients who benefit from sinus rhythm.

OBJECTIVES: The European Society of Thoracic Surgeons and the European Association for Cardio-Thoracic Surgery designed a questionnaire to assess the impact of gender bias on a cardiothoracic surgery career. METHODS: A 46-item survey investigating gender bias was designed using online survey software from December 2020 to January 2021. All European Society of Thoracic Surgeons and European Association for Cardio-Thoracic Surgery members and non-members included in the mailing lists were invited to complete an electronic survey. Descriptive statistics and a comparison between gender groups were performed. RESULTS: Our overall response rate was 11.5% (1118/9764), of which 36.14% were women and 63.69% were men. Women were more likely to be younger than men (P < 0.0001). A total of 66% of the women reported having no children compared to only 19% of the men (P < 0.0001). Only 6% of women vs 22% of men were professors. More women (72%) also reported never having been a formal mentor themselves compared to men (38%, P < 0.0001). A total of 35% of female respondents considered leaving surgery because of episodes of discrimination compared to 13% of men; 67% of women said that they experienced being unfairly treated due to gender discrimination. Of the male surgeons, 31% reported that they were very satisfied with their career compared to only 17% of women (P < 0.0001). CONCLUSIONS: Women in cardiothoracic surgery reported significantly high rates of experiences with bias that may prevent qualified women from advancing to positions of leadership. Efforts to mitigate bias and support the professional development of women are at the centre of newly formed European committees.

PURPOSE: Despite the minimally invasive nature of transanal hemorrhoidal dearterialization (THD) with Doppler arterial identification procedures, hemorrhoidectomy is still considered the gold standard procedure for hemorrhoidal disease. However, the classical techniques of hemorrhoidectomy have a high rate of postoperative complications. The main purpose of this study is to demonstrate the efficacy and complications of these techniques used for grades II and III hemorrhoids. METHODS: A retrospective (case-control) study was carried out from January 2009 to May 2014, and all patients undergoing surgical procedures for hemorrhoidal disease in two French clinics were considered. Application of inclusion and exclusion criteria identified 270 eligible patients (163 undergoing Doppler THD and 107 treated with Milligan Morgan hemorrhoidectomy). Statistical analysis was calculated considering immediate postoperative complications, functional results, chronic complications, and recurrences. RESULTS: Analysis of primary outcomes showed a significant difference between the 2 groups concerning postoperative pain, which had a lower rate in THD (P = 0.0001) and in postoperative bleeding (P = 0.02) than hemorrhoidectomy. However, long-term follow-up at three years showed a superior rate of recurrence in the THD group (P = 0.009). CONCLUSION: The THD technique is a safe and effective procedure for grades II and III hemorrhoids, has lower rates of post-operative pain and bleeding, and allows faster hospital discharge; however, it also shows a higher rate of recurrence at three years of follow-up.
RESUMO
INTRODUCTION: Ingestion of foreign bodies including dentures, fishbone, screw, and/or surgical devices can be a cause of morbidity, and it rarely could be fatal. PRESENTATION OF CASE: We present the first hitherto reported case of mussel shell ingestion, which caused acute abdominal pain in a 55-year-old woman. The shell pierced ileal loops, and it was found in the abdominal cavity. DISCUSSION: The accidental or voluntary ingestion of a foreign body is an uncommon event compared to the other causes of bowel perforation. It is fundamental to immediately remove the intestinal fluid, repair the tear, and prevent sepsis, because each delay in diagnosis can lead to a worst outcome. CONCLUSION: In case of bowel perforation, it important for surgeons, who are dealing with these acute care patients, to be aware of different designs and constructions of possible foreign bodies, in order to be prepared to deal with different possible scenarios and be able to manage them properly.
RESUMO
Cyclic AMP response element binding (CREB) protein is a member of the CREB/activating transcription factor (ATF) family of transcription factors that play an important role in the cell response to different environmental stimuli leading to proliferation, differentiation, apoptosis, and survival. A number of studies highlight the involvement of CREB in the resistance to ionizing radiation (IR) therapy, demonstrating a relationship between IR-induced CREB family members' activation and cell survival. Consistent with these observations, we have recently demonstrated that CREB and ATF-1 are expressed in leukemia cell lines and that low-dose radiation treatment can trigger CREB activation, leading to survival of erythro-leukemia cells (K562). On the other hand, a number of evidences highlight a proapoptotic role of CREB following IR treatment of cancer cells. Since the development of multiple mechanisms of resistance is one key problem of most malignancies, including those of hematological origin, it is highly desirable to identify biological markers of responsiveness/unresponsiveness useful to follow-up the individual response and to adjust anticancer treatments. Taking into account all these considerations, this mini-review will be focused on the involvement of CREB/ATF family members in response to IR therapy, to deepen our knowledge of this topic, and to pave the way to translation into a therapeutic context.
RESUMO
Fungal endocarditis is rare in comparison with bacterial endocarditis and is associated with a poor prognosis. Despite the proven reliability of echocardiography, false negatives are not uncommon and may influence the therapeutic strategy, as some reports have supported the efficacy of antifungal treatment alone. We report on a case of bioprosthetic aortic valve Candida parapsilosis endocarditis without typical echocardiograhy findings, which we treated with both antifungal and surgical therapy.

BACKGROUND: It is important to establish an early diagnosis of the Marfan Syndrome (MFS) for providing an adequate pharmacological or surgical therapy. Nevertheless, this diagnosis may be complex, given the multi-organic involvement of this disease. AIMS: In this work, we evaluated the oral phenotype in a group of paediatric patients with a clinical diagnosis of MFS, to quantify the association of the oro-facial defects with other systemic alterations. SETTINGS AND DESIGN: Paediatric subjects who were aged, with a clinical diagnosis of MFS, were selected from our regional Marfan monitoring unit. METHODS AND MATERIAL: All the patients were subjected to Paediatric Dentistry examinations and a radiological screening with Panoramic and Cephalometric X-Rays. The aortic dilation (Aortic Z-score value), the hyperlaxity of the ligaments and scoliosis were evaluated by cardio-surgical and orthopaedics specialists. STATISTICAL ANALYSIS: The correlations between the oral and systemic alterations were analyzed by using the chi square test for the nominal variables. RESULTS AND CONCLUSIONS: We found a significant correlation of the Aortic Z - score with multiple oral defects which included retrognathia, malar hypoplasia, cross bite, oral respiration and an ogival palate. An association of the oral defects with hyperlaxity of the ligaments and scoliosis was also found. Thus, the data suggested that dentists should be more involved in a multidisciplinary approach, to provide an early MFS diagnosis in paediatric patients.
RESUMO
BACKGROUND: Subcommissural aortic annuloplasty (SCA) has been recommended for treatment of functional aortic regurgitation (AR), but its association with sinotubular junction adjustment is still controversial. METHODS: Sixty patients with moderate or severe functional AR secondary to proximal ascending aorta aneurysm operated on between May 2004 and December 2010 were reviewed. Forty patients underwent SCA and ascending aorta repair (SCA group; mean age, 65 ± 9 years) and 20 underwent ascending aorta repair alone (non-SCA group; mean age, 69 ± 8 years). Preoperative AR grades were comparable between groups (p = 0.9). Echocardiographic data at discharge and during follow-up (SCA group, 41 ± 13 months; non-SCA group, 46 ± 13 months) were analyzed. RESULTS: Improvement of mean AR grade was better in the SCA group than in the non-SCA group at discharge (0.78 ± 0.9 vs 1.8 ± 0.1/4+, p = 0.0001) and at follow-up (0.44 ± 0.8 vs 2.4 ± 0.7/4+, p = 0.0001). Cox-regression analysis (odds ratio [95% confidence interval]) identified a higher residual AR at discharge (0.14 [0.012-0.37], p = 0.02) and the surgical technique, SCA or not (0.5 [0.03-0.899], p = 0.04), as predictors of more than grade 2/4+ AR at follow-up. Five-year freedom from more than grade 2/4+ AR was 94.4% ± 5.4% vs 58% ± 16% in SCA vs non-SCA (p = 0.02), respectively, and the survival rate was 95% ± 5% vs 89% ± 7.5% (p = 0.7). No valve stenosis was observed in the SCA group. CONCLUSIONS: SCA is effective for treatment of functional AR, providing stable results even for significant AR. Our results suggest that it should be possibly associated to sinotubular junction adjustment. SCA seems to not impair normal aortic valve opening.
