RESUMO

There is increasing knowledge in the recognition of individuals at risk for progression to rheumatoid arthritis (RA) before the clinical manifestation of the disease. This prodromal phase preceding the manifestation of RA may represent a "window of opportunity" for preventive interventions that may transform the clinical approach to this disease. However, limited evidence exists in support of effective interventions to delay the onset or even halt the manifestation of RA. Given the multifactorial nature of RA development and disease progression, the latest guidelines for established RA stress the use of integrative interventions and multidisciplinary care strategies, combining pharmacologic treatment with non-pharmacological approaches. Accordingly, individuals at risk of RA could be offered an integrative, multifactorial intervention approach. Current data point toward pharmacological intervention reverting the subclinical inflammation and delay in the disease onset. In addition, targeting life style modifiable factors (smoking cessation, dental health, physical activity, and diet) may presumably improve RA prognosis in individuals at risk, mainly by changes in epigenetics, autoantibodies, cytokines profiles, and microbiome. Nonetheless, the benefits of multidisciplinary interventions to halt the manifestation of RA in at-risk individuals remain unknown. As there is a growing knowledge of possible pharmacological intervention in the preclinical phase, this narrative review aims to provide a comprehensive overview of non-pharmacological treatments in individuals at risk of RA. Considering the mechanisms preceding the clinical manifestation of RA we explored all aspects that would be worth modifying and that would represent an integrative non-pharmacological care for individuals at risk of RA.

RESUMO

OBJECTIVES: To establish proof of concept of a prehabilitation intervention, a combination of education and behavioural change, preceding a physical activity programme in people with fibromyalgia (FM). SETTINGS: Open-label, feasibility clinical trial. PARTICIPANTS: Eleven people with FM (10 women). INTERVENTIONS: The prehabilitation intervention consisted of 4 weeks, 1 weekly session (~1 to 1.5 hours), aimed to increase self-efficacy and understand why and how to engage in a gentle and self-paced physical activity programme (6 weeks of walking with telephone support). PRIMARY AND SECONDARY OUTCOME MEASURES: Primary outcome was the acceptability and credibility of the intervention by means of the Credibility/Expectancy Questionnaire. Secondary outcomes comprised scales to measure FM severity, specific symptoms and sedentary behaviour. An exit interview was conducted to identify the strengths and weaknesses and barriers to the intervention. RESULTS: One participant dropped out due to finding the walking programme excessively stressful. Participants expected the intervention would improve their symptoms by 22%-38% but resulted in 5%-26% improvements. Participants would be confident in recommending this intervention to a friend who experiences similar problems. The interviews suggested that the fluctuation of symptoms should be considered as an outcome and that the prehabilitation intervention should accomodate these fluctuation. Additional suggestions were to incorporate initial interviews (patient-centred approach), to tailor the programmes to individuals' priorities and to offer a variety of physical activity programmes to improve motivation. CONCLUSIONS: This feasibility study demonstrated that our novel approach is acceptable to people with FM. Future interventions should pay attention to flexibility, symptoms fluctuation and patients support. TRIAL REGISTRATION NUMBER: NCT03764397.

RESUMO

BACKGROUND: Simultaneous pancreas-kidney transplantation (SPK) is still characterized by high rates of postoperative complications. This study aims to offer an in-depth characterization of early, medium-term, and late complications following SPK to derive insights for postoperative management and follow-up. METHODS: Consecutive SPK transplantations were analysed. Pancreatic graft (P-graft)- and kidney graft (K-graft)-related complications were analysed separately. The global postoperative course was assessed in three timeframes (early, medium-term, and late) using the comprehensive complication index (CCI). Predictors of complications and early graft loss were explored. RESULTS: Complications occurred in 61.2% of patients, and the 90-day mortality was 3.9%. The overall burden of complications was significantly high during admission (CCI 22.4 ± 21.1) and decreased gradually afterwards. P-graft-related complications burdened the most in the early postoperative course (CCI 11.6 ± 13.8); postoperative ileus and perigraft fluid collection were the most frequent complications, and pseudoaneurysms, haemorrhages, and bowel leaks were the major concerns. K-related complications were milder but represented the largest proportion of the CCI in the late postoperative timeframe (CCI 7.6 ± 13.6). No predictors of P-graft- or K-graft-related complications were found. CONCLUSION: Pancreas graft-related complications represent the largest part of the clinical burden in the early postoperative timeframe but are negligible after 3 months. Kidney grafts have a relevant impact in the long term. The multidisciplinary approach to SPK recipients should be driven based on all graft-specific complications and tailored on a time-dependent basis.

RESUMO

BACKGROUND: Although numerous comparisons between conventional Two Stage Hepatectomy (TSH) and Associating Liver Partition and Portal Vein Ligation for staged hepatectomy (ALPPS) have been reported, the heterogeneity of malignancies previously compared represents an important source of selection bias. This systematic review and meta-analysis aimed to compare perioperative and oncological outcomes between TSH and ALPPS to treat patients with initially unresectable colorectal liver metastases (CRLM). METHODS: Main electronic databases were searched using medical subject headings for CRLM surgically treated with TSH or ALPPS. Patients treated for primary or secondary liver malignancies other than CRLM were excluded. RESULTS: A total of 335 patients from 5 studies were included. Postoperative major complications were higher in the ALPPS group (relative risk [RR] 1.46, 95% confidence interval [CI] 1.04-2.06, I2 = 0%), while no differences were observed in terms of perioperative mortality (RR 1.53, 95% CI 0.64-3.62, I2 = 0%). ALPPS was associated with higher completion of hepatectomy rates (RR 1.32, 95% CI 1.09-1.61, I2 = 85%), as well as R0 resection rates (RR 1.61, 95% CI 1.13-2.30, I2 = 40%). Nevertheless, no significant differences were achieved between groups in terms of overall survival (OS) (RR 0.93, 95% CI 0.68-1.27, I2 = 52%) and disease-free survival (DFS) (RR 1.08, 95% CI 0.47-2.49, I2 = 54%), respectively. CONCLUSION: ALPPS and TSH to treat CRLM seem to have comparable operative risks in terms of mortality rates. No definitive conclusions regarding OS and DFS can be drawn from the results.

RESUMO

BACKGROUND: Multiple treatment options at glioblastoma progression exist, including reintervention, reirradiation, additional systemic therapy, and novel strategies. No alternative has been proven to be superior in terms of postprogression survival (PPS). A second surgery has shown conflicting evidence in the literature regarding its prognostic impact, possibly affected by selection bias, and might benefit a sparse subset of patients with recurrent glioblastoma. The present study aims to determine the prognostic influence of salvage procedures in a cohort of patients treated in the same institution over 15 years. METHODS: Three hundred and fifty patients with confirmed primary glioblastoma diagnosed and treated between 2005 and 2019 were selected. To examine the role of reoperation, we intended to create comparable groups, previously excluding all diagnostic biopsies and patients who were not actively treated after the first surgery or at disease progression. Uni- and multivariate Cox proportional hazards regression models were employed, considering reintervention as a time-fixed or time-dependent covariate. The endpoints of the study were overall survival (OS) and PPS. RESULTS: At progression, 33 patients received a second surgery and 84 were treated with chemotherapy only. Clinical variables were similar among groups. OS, but not PPS, was superior in the reintervention group. Treatment modality had no impact in our multivariate Cox regression models considering OS or PPS as the endpoint. CONCLUSIONS: The association of reoperation with improved prognosis in recurrent glioblastoma is unclear and may be influenced by selection bias. Regardless of our selective indications and high gross total resection rates in second procedures, we could not observe a survival advantage.

RESUMO

BACKGROUND: A definition of pancreatic fistula specifically addressing pancreas transplantation (PT) is lacking. This study sought to characterize pancreatic fistula in this setting and to define its clinical relevance on the postoperative course and long-term graft survival (GS). METHODS: Consecutive simultaneous pancreas and kidney transplantations were analysed. The global postoperative course was assessed through the comprehensive complication index (CCI). PF was defined according to the original International Study Group for Pancreatic Surgery (ISGPS) definition. Predictors of poor postoperative course and GS were explored. RESULTS: Seventy-eight patients were analysed. Surgical morbidity was 48.7%, with severe complications occurring in 39.7%. Ninety-day mortality was 2.6%. PF occurred in 56.6% of patients, although its average clinical burden was low and did not correlate with either early or long-term outcomes. Peri-graft fluid collections, postoperative day (POD) 1 drain fluid amylase (DFA) ≥ 2200 U/L, and POD 5 DFA/serum amylase ratio ≥7.0 independently correlated with poor postoperative course. Perigraft fluid collections were associated with reduced GS. CONCLUSION: Conventionally defined pancreatic fistula is frequent following PT, although its clinical impact is negligible. To define clinically relevant PF, novel cut-offs for DFA might be pondered in a future series, while perigraft fluid collections should be strongly considered.

RESUMO

Lipomas are the commonest benign tumour, made up exclusively of adipose tissue, and can arise anywhere in the body. However, giant lipomas of the hand, defined as >5 cm in diameter, are rare. They have the potential to invade into surrounding areas and cause a multitude of symptoms due to the compression and proximity of underlying structures. We describe a case of a 64-year-old woman who presents with a swelling of the left thenar eminence, associated with numbness and tingling in all fingers. Magnetic resonance imaging and nerve conduction studies confirmed the diagnosis of a lipoma causing median nerve compression. The patient underwent elective surgical excision with good postoperative recovery. The excised lesion, measuring 12 × 7 × 2.4 cm, is one of the largest giant lipomas of the hand reported in literature, and the first to demonstrate invasion from the mid palmar space into both the dorsal sub-aponeurotic space and carpal tunnel.

RESUMO

BACKGROUND: Surgery for hand trauma accounts for a significant proportion of the plastic surgery trainee activity. The aim of this article is to create a standardised simulation training module for flexor tendon repair techniques for residents prior to their first encounter in the clinical setting. METHODS: A step-ladder approach flexor tendon repair training with four levels of difficulty was conducted using a three-dimensional (3D) printed anatomical simulation model and a silicone tendon rod on a cohort of 28 plastic surgery Senior House Officers (SHOs) of various stages in their training (n=28). Assessment of knowledge (online questionnaire) and practical skills using validated score systems (global rating scale and task specific score) was performed at the beginning and end of the module by hand experts of our unit. RESULTS: The overall average knowledge-based scores of the cohort pre- and post-assessment were 1.48/5 (29.6%) and 3.56/5 (71.5%), respectively. The overall average skills-based scores of the cohort pre- and post-assessments were 3.05/5 (61%) and 4.12/5 (82.5%), respectively. Significant (p<0.01) difference of improvement of knowledge and skills was noted on all trainees. All trainees confirmed that the training module improved their confidence with flexor tendon repair. CONCLUSION: We demonstrate a standardised simulation training framework that employs a 3D printed flexor tendon simulation model proven to improve the skills of residents especially during their early learning curve and which paves the way to a more universal, standardised and validated training across hand surgery.

RESUMO

BACKGROUND: Hepatectomy in patients with large tumor load may result in postoperative liver failure and associated complications due to excessive liver parenchyma removal. Conventional two-stage hepatectomy (TSH) and associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) technique are possible solutions to this problem. Colorectal liver metastases (CRLM) is the most frequent indication, and there is a need to assess outcomes for both techniques to improve surgical and long-term oncological outcomes in these patients. METHODS: A single-center retrospective study was designed to compare TSH with ALPPS in patients with initially unresectable bilateral liver tumors between January 2005 and January 2020. ALPPS was performed from January 2012 onwards as the technique of choice. Long-term overall survival (OS) and disease-free survival (DFS) were evaluated as primary outcome in CRLM patients. Postoperative morbidity, mortality and liver growth in all patients were also evaluated. RESULTS: A total of 38 staged hepatectomies were performed: 17 TSH and 21 ALPPS. Complete resection rate was 76.5% (n = 13) in the TSH group and 85.7% (n = 18) in the ALPPS group (P = 0.426). Overall major morbidity (Clavien-Dindo ≥ 3a) (stage 1 + stage 2) was 41.2% (n = 7) in TSH and 33.3% (n = 7) in ALPPS patients (P = 0.389), and perioperative 90-day mortalities were 11.8% (n = 2) vs. 19.0% (n = 4) in each group, respectively (P = 0.654). Intention-to-treat OS rates at 1 and 5 years in CRLM patients for TSH (n = 15) were 80% and 33%, and for ALPPS (n = 17) 76% and 35%, respectively. DFS rates at 1 and 5 years were 36% and 27% in the TSH group vs. 33% and 27% in the ALPPS group, respectively. CONCLUSIONS: ALPPS is an effective alternative to TSH in bilateral affecting liver tumors, allowing higher resection rate, but patients must be carefully selected. In CRLM patients similar long-term OS and DFS can be achieved with both techniques.

RESUMO

BACKGROUND AND OBJECTIVE: Cerebral edema is a frequent and serious complication of traumatic brain injury (TBI). Diffusion tensor imaging (DTI) is considered a useful technique to assess white matter integrity after TBI. The objective of this prospective, observational study was to assess the characteristics of the vasogenic edema in the traumatic pericontusional tissue and compare it to the vasogenic edema found in brain tumors. We also included a control group. METHODS: Using DTI, the Apparent diffusion coefficient (ADC) and Fractional anisotropy (FA) were measured in the area of vasogenic edema in both TBI and tumor patients. The measurements in the control group were done in the gray and white matter. We included 15 TBI patients, 18 tumor patients and 15 controls. RESULTS: ADC and FA showed no differences between TBI and tumor patients (p=0.27 for AF; p=0.79 for ADC). Compared to healthy controls, TBI and tumor patients presented higher ADC values and lower FA values. The differences between TBI and controls were statistically significant (p<0.05). CONCLUSIONS: In this prospective observational study using DTI-MRI in a selected group of mild and moderate TBI patients with vasogenic pericontusional edema we have shown that there were no significant differences of the ADC and FA values compared to brain tumor patients. Furthermore, healthy controls showed significant lower ADC values and higher FA values compared to TBI and tumor patients. Future studies, using DTI-MRI, should address whether any therapy has a favorable impact on the vasogenic edema of TBI patients with brain contusions.

RESUMO

Immunization with Plasmodium falciparum (Pf) sporozoites under chemoprophylaxis (PfSPZ-CVac) is the most efficacious approach to malaria vaccination. Implementation is hampered by a complex chemoprophylaxis regimen and missing evidence for efficacy against heterologous infection. We report the results of a double-blinded, randomized, placebo-controlled trial of a simplified, condensed immunization regimen in malaria-naive volunteers (EudraCT-Nr: 2018-004523-36). Participants are immunized by direct venous inoculation of 1.1 × 105 aseptic, purified, cryopreserved PfSPZ (PfSPZ Challenge) of the PfNF54 strain or normal saline (placebo) on days 1, 6 and 29, with simultaneous oral administration of 10 mg/kg chloroquine base. Primary endpoints are vaccine efficacy tested by controlled human malaria infection (CHMI) using the highly divergent, heterologous strain Pf7G8 and safety. Twelve weeks following immunization, 10/13 participants in the vaccine group are sterilely protected against heterologous CHMI, while (5/5) participants receiving placebo develop parasitemia (risk difference: 77%, p = 0.004, Boschloo's test). Immunization is well tolerated with self-limiting grade 1-2 headaches, pyrexia and fatigue that diminish with each vaccination. Immunization induces 18-fold higher anti-Pf circumsporozoite protein (PfCSP) antibody levels in protected than in unprotected vaccinees (p = 0.028). In addition anti-PfMSP2 antibodies are strongly protection-associated by protein microarray assessment. This PfSPZ-CVac regimen is highly efficacious, simple, safe, well tolerated and highly immunogenic.

RESUMO

The aim of this study was to determine the effect of changes in cardiopulmonary fitness on the mental health of patients with severe obesity who underwent gastric bypass surgery (prior to and 1, 3, and 6 months after surgery). Study participants were recruited from among patients of a regional hospital in Czechia who underwent gastric bypass surgery between April 2018 and October 2019. They were eligible if they (a) were between 18 and 65 years old, (b) provided written informed consent, and (c) were able to walk independently. Twenty-six patients (age 45.4 ± 9.0 years, body mass index 45.1 ± 7.4 kg·m-2, body fat 43.8 ± 4.8%) were included in the analysis. The key finding revealed that the greater the increase in cardiopulmonary fitness (i.e., longer distance walked in the six-minute walk test, 6MWT), the better the improvement in depression score among patients who underwent bariatric surgery. In particular, increments of 10 m in the 6MWT lead to the improvement of 0.5 points on the depression subscale of the Hospital Anxiety and Depression Scale (HADS) questionnaire. As the main implication, these results suggest that patients should participate in exercise training programs to increase their fitness status for optimal physical and mental outcomes of bariatric surgery.

RESUMO

Indications and outcomes of extended pancreatectomies have been recently appraised by the International Study Group for Pancreatic Surgery. However, no definitive conclusions have been drawn, particularly in the setting of neoadjuvant treatments. We present here a case of 53-year-old man diagnosed with a bulky adenocarcinoma of the tail of the pancreas and infiltrating the adjacent organs and the thoracic wall. The patient was sent to neoadjuvant chemotherapy and he underwent 12 cycles of FOLFIRINOX. Since a significant radiological response was observed after chemotherapy, the patient was scheduled for extended distal pancreatectomy with en bloc resection of the thoracic wall, in order to achieve a radical resection. The surgery is herein described with all technical details. The patient was discharged after an uneventful early post-operative course and subsequently readmitted for a late grade B post-operative pancreatic fistula, which was ultimately treated successfully. Pathology showed complete response. When performed in centers with ample experience in pancreatic surgery, extended pancreatic resections represent a viable curative option with acceptable surgical outcomes. In this setting, challenging tailored resections should be considered to achieve negative margins, particularly following maximized effective downstaging strategies.

RESUMO

To summarize the long-term complications after pancreas transplantation that affect graft function, a literature search was carried out on the long-term complications of pancreatic transplantation, namely, complications from postoperative 3rd mo onwards, in terms of loss of graft function, late infection and vascular complications as pseudoaneurysms. The most relevant reviews and studies were selected to obtain the current evidence on these topics. The definition of graft failure varies among different studies, so it is difficult to evaluate, a standardized definition is of utmost importance to know the magnitude of the problem in all worldwide series. Chronic rejection is the main cause of long-term graft failure, occurring in 10% of patients. From the 3rd mo of transplantation onwards, the main risk factor for late infections is immunosuppression, and patients have opportunistic infections like: Cytomegalovirus, hepatitis B and C viruses, Epstein-Barr virus and varicella-zoster virus; opportunistic bacteria, reactivation of latent infections as tuberculosis or fungal infections. Complete preoperative studies and serological tests should be made in all recipients to avoid these infections, adding perioperative prophylactic treatments when indicated. Pseudoaneurysm are uncommon, but one of the main causes of late bleeding, which can be fatal. The treatment should be performed with radiological endovascular approaches or open surgery in case of failure. Despite all therapeutic options for the complications mentioned above, transplantectomy is a necessary option in approximately 50% of relaparotomies, especially in life-threatening complications. Late complications in pancreatic transplantation threatens long-term graft function. An exhaustive follow-up as well as a correct immunosuppression protocol are necessary for prevention.

RESUMO

OBJECTIVES: Since the introduction of endovascular treatment for cerebral aneurysms, hospitals in which subarachnoid hemorrhage is treated show different availability and/or preferences towards both treatment modalities. The main aim is to evaluate the clinical and angiographic results according to the hospital's treatment preferences applied. METHODS: This study was conducted based on use of the subarachnoid hemorrhage database of the Vascular Pathology Group of the Spanish Neurosurgery Society. Centers were classified into 3 subtypes according to an index in the relationship between endovascular and surgical treatment as: endovascular preference, high endovascular preference, and elevated surgical preference. The clinical results and angiographic results were evaluated among the 3 treatment strategies. RESULTS: From November 2004 to December 2017, 4282 subarachnoid hemorrhage patients were selected for the study: 630 (14.7%) patients from centers with surgical preference, 2766 (64.6%) from centers with endovascular preference, and 886 (20.7%) from centers with high endovascular preference. The surgical preference group obtained the best angiographic results associated with a greater complete exclusion (odds ratio: 1.359; 95% confidence interval: 1.025-1.801; P = 0.033). The surgical preference subgroup obtained the best outcome at discharge (65.45%), followed by the high endovascular preference group (61.5%) and the endovascular preference group (57.8%) (odds ratio: 1.359; 95% confidence interval: 1.025-1.801; P = 0.033). CONCLUSIONS: In Spain, there is significant variability in aneurysm exclusion treatment in aneurysmal subarachnoid hemorrhage. Surgical centers offer better results for both surgical and endovascular patients. A multidisciplinary approach and the maintenance of an elevated quality of surgical competence could be responsible for these results.

RESUMO

Guidelines recommend temporal artery biopsy (TAB) for patients suspected of having giant cell arteritis (GCA). We evaluated the impact of TAB on the diagnosis and management of patients with suspected GCA at a tertiary plastic surgery unit. METHODS: A retrospective review of all TAB procedures performed at our centre over 7 years was performed. One hundred and one patients were included in the study. Patients were classified into 3 diagnostic groups: confirmed (positive TAB), presumed (negative TAB with high clinical suspicion) and unlikely (negative TAB with low clinical suspicion). The clinical presentation and management for each group were compared. RESULTS: The average American College of Rheumatology (ACR) score was 3.07. The number of patients with an ACR score of ≥3 before TAB was 72 (71.3%) and remained the same after TAB. The number of patients who remained on steroid therapy was lower in the group with an unlikely diagnosis of GCA compared to the group with a confirmed diagnosis (p<0.05). Conversely, there was no significant difference in steroid therapy between those with a presumed and confirmed diagnosis (p>0.05). CONCLUSIONS: This study found a significant difference in steroid treatment between those with confirmed GCA and those where the diagnosis was unlikely showing that TAB may support decisions regarding steroid therapy. However, TAB was inappropriately requested for patients whose pre-TAB ACR score was ≥3 as this score is sufficient for the diagnosis of GCA. Therefore, the use of TAB should be limited to cases of diagnostic uncertainty.

RESUMO

True aneurysms of the arteries of the hand are vanishingly rare. We report a case detailing the surgical management of a 44-year old gentleman with a true common digital artery aneurysm. This report adds to the current sparse literature on digital artery aneurysms and their presentation, investigation and management.

RESUMO

INTRODUCTION: The good results obtained with the implementation of ambulatory laparoscopic cholecystectomy programs have led to the expansion of the initial inclusion criteria. The main objective was to evaluate the results and the degree of satisfaction of the patients included in a program of laparoscopic cholecystectomy without admission, with expanded criteria. METHODS: Observational study of a cohort of 260 patients undergoing ambulatory laparoscopic cholecystectomy between April 2013 and March 2016 in a third level hospital. We classified the patients into 2groups based on compliance with the initial inclusion criteria of the outpatient program. Group I (restrictive criteria) includes 164 patients, while in group ii (expanded criteria) we counted 96 patients. We compared the surgical time, the rate of failures in ambulatory surgery, rate of conversion, reinterventions and mortality and the satisfaction index. RESULTS: The overall success rate of ambulatory laparoscopic cholecystectomy was 92.8%. The most frequent cause of unexpected income was for medical reasons. There was no statistically significant difference between the 2groups for total surgery time, the rate of conversion to open surgery and the number of major postoperative complications Do not demostrate differences in surgical time, nor in the number of perioperative complications (major complications 1,2%), or the number of failures in ambulatory surgery, nor the number of readmissions between both groups. There was no death. 88.5% of patients completed the survey, finding no differences between both groups in the patient satisfaction index. The overall score of the process was significantly better in group ii(P=.023). CONCLUSIONS: Ambulatory laparoscopic cholecystectomy is a safe procedure with a good acceptance by patients with expanded criteria who were included in the surgery without admission program.

RESUMO

Grapevine cluster compactness has a clear impact on fruit quality and health status, as clusters with greater compactness are more susceptible to pests and diseases and ripen more asynchronously. Different parameters related to inflorescence and cluster architecture (length, width, branching, etc.), fruitfulness (number of berries, number of seeds) and berry size (length, width) contribute to the final level of compactness. From a collection of 501 clones of cultivar Garnacha Tinta, two compact and two loose clones with stable differences for cluster compactness-related traits were selected and phenotyped. Key organs and developmental stages were selected for sampling and transcriptomic analyses. Comparison of global gene expression patterns in flowers at the end of bloom allowed identification of potential gene networks with a role in determining the final berry number, berry size and ultimately cluster compactness. A large portion of the differentially expressed genes were found in networks related to cell division (carbohydrates uptake, cell wall metabolism, cell cycle, nucleic acids metabolism, cell division, DNA repair). Their greater expression level in flowers of compact clones indicated that the number of berries and the berry size at ripening appear related to the rate of cell replication in flowers during the early growth stages after pollination. In addition, fluctuations in auxin and gibberellin signaling and transport related gene expression support that they play a central role in fruit set and impact berry number and size. Other hormones, such as ethylene and jasmonate may differentially regulate indirect effects, such as defense mechanisms activation or polyphenols production. This is the first transcriptomic based analysis focused on the discovery of the underlying gene networks involved in grapevine traits of grapevine cluster compactness, berry number and berry size.
