RESUMO

BACKGROUND: In the field of academic cardiology, the assessment of an author's scholarly impact and professional progression heavily relies on publications and citations. This study investigates whether specific cardiology expertise correlates with accelerated professional growth. METHODS: Using data from the 2023 European Society of Cardiology congress, 948 faculty attendees with an h-index of 30 or higher were analyzed. Expertises were categorized into six groups, and their association with publications and citations peaks was explored. RESULTS: Interventional cardiologists exhibited the highest annual publication peak, followed by imaging and electrophysiology experts. However, no significant differences were observed in citation peaks among expertise groups. While imaging experts initially appeared to reach citation peaks faster, this effect diminished after statistical adjustments. Additionally, holding multiple expertise areas prolonged the time to reach publication and citation peaks by approximately six years. CONCLUSION: This study underscores the influence of expertise in interventional cardiology on publication peaks but suggests that citation peaks and career progression velocity remain unaffected by expertise type. Furthermore, it highlights that holding multiple areas of expertise slowers the attainment of career peak for scholarly authors.

RESUMO

Extracellular vesicles (EVs) are lipid bilayers derived from cell membranes, released by both eukaryotic cells and bacteria into the extracellular environment. During production, EVs carry proteins, nucleic acids, and various compounds, which are then released. While Gram-positive bacteria were traditionally thought incapable of producing EVs due to their thick peptidoglycan cell walls, recent studies on membrane vesicles (MVs) in Gram-positive bacteria have revealed their significant role in bacterial physiology and disease progression. This review explores the current understanding of MVs in Gram-positive bacteria, including the characterization of their content and functions, as well as their interactions with host and bacterial cells. It offers a fresh perspective to enhance our comprehension of Gram-positive bacterial EVs.

RESUMO

The evolution of anticoagulation therapy, from vitamin K antagonists to the advent of direct oral anticoagulants (DOACs) almost two decades ago, marks significant progress. Despite improved safety demonstrated in pivotal trials and post-marketing observations, persistent concerns exist, particularly regarding bleeding risk and the absence of therapeutic indications in specific subgroups or clinical contexts. Factor XI (FXI) has recently emerged as a pivotal contributor to intraluminal thrombus formation and growth, playing a limited role in sealing vessel wall injuries. Inhibiting FXI presents an opportunity to decouple thrombosis from hemostasis, addressing concerns related to bleeding events while safeguarding against thromboembolic events. Notably, FXI inhibition holds promise for patients with end-stage renal disease or cancer, where clear indications for DOACs are currently lacking. Various compounds have undergone design, testing, and progression to phase 2 clinical trials, demonstrating a generally favorable safety and tolerability profile. However, validation through large-scale phase 3 trials with sufficient power to assess both safety and efficacy outcomes is needed. This review comprehensively examines FXI inhibitors, delving into individual classes, exploring their pharmacological properties, evaluating the latest evidence from randomized trials, and offering insights into future perspectives.

RESUMO

INTRODUCTION: Hernia repair using prosthetic mesh materials has become the preferred method of repair, as the recurrence rates are much lower than with conventional repair techniques. The aim of this retrospective study was to compare open small- and medium-sized abdominal wall hernia repair with flat patch mesh versus three-dimensional mesh (plug) in terms of recurrence and complication rates. METHODS: The medical records of 300 patients who underwent abdominal wall hernia repair using flat patch mesh versus three-dimensional mesh between January 2010 to December 2015 were reviewed. All patients were followed up after 1 month, 3 month and 1 year. The rate of recurrence, and short-term postoperative complications such as incidence of Surgical Site Infections (SSIs), hematoma and seroma were evaluated. RESULTS: Short-term follow-up data were available for all patients. The first group was composed of 150 patients that were treated with a flat polypropylene mesh (68% presened umbilical hernia and 32% presented epigastric hernia). The second group was composed of 150 patients that were treated with a three-dimensional polypropylene mesh (60% presented umbilical hernia and 40% presented epigastric hernia). The majority of postoperative (1-month) complications were wound related, representing superficial SSI or seroma. Our results showed a statistically significant reduction of SSIs [3 (2%) vs 13 (8.6%); p = 0.038] and seroma [2 (1.3%) vs 12 (8%); p = 0.030] in the group of patients treated with plugs compared to flat-mesh group. There was no statistically significant difference in hernia recurrences. DISCUSSION: Usage three-dimensional mesh for open small- and medium-sized umbilical or epigastric hernia repair represents a feasible and safe technique that significantly lowers the incidence of complications such as SSIs and seroma. Furthermore, compared to flat patch mesh, plugs displayed non-inferiority in terms recurrence. Further, well-designed clinical trials could be realized to investigate possible applications of plugs in treatment of small- and medium-sized umbilical and epigastric hernias. KEY WORDS: Mesh, Umbilical Hernia.

RESUMO

In Italy, about 100,000 cholecystectomies are carried out annually, the majority of them laparoscopically. Complications following cholecystectomy are common and increase morbidity and cost burden. Biliary damage (0.08-0.5%), bile leak (0.42-1.1%), retained common bile duct stones (0.8-5.7%), postcholecystectomy syndrome (10-15%), and postcholecystectomy diarrhea (5-12%) are a few of the most often occurring laparoscopic cholecystectomy consequences. In many instances, endoscopy can offer conclusive management and is crucial for the identification and treatment of biliary problems. Regarding the ideal treatment strategy for biliary problems, there is no universal agreement. A skilled interdisciplinary team should therefore approach biliary problems. The surgeon must be knowledgeable on how to handle these issues.

RESUMO

Laparoscopic right hemicolectomy represents an effective therapeutic approach for right colon cancer (RCC). The primary aim of this study was to evaluate bowel function recovery, length of hospital stay, operative time, and the number of general and anastomosis-related postoperative complications from intracorporeal anastomosis (ICA) vs. extracorporeal anastomosis (ECA); the secondary outcome was the number of lymph nodes retrieved. This observational study was conducted on 108 patients who underwent right hemicolectomy for RCC; after surgical resection, 64 patients underwent ICA and 44 underwent ECA. The operative time was slightly longer in the ICA group than in the ECA group, even though the difference was not significant (199.31 ± 48.90 min vs. 183.64 ± 35.80 min; p = 0.109). The length of hospital stay (7.53 ± 1.91 days vs. 8.77 ± 3.66 days; p = 0.036) and bowel function recovery (2.21 ± 1.01 days vs. 3.45 ± 1.82 days; p < 0.0001) were significantly lower in the ICA group. There were no significant differences in postoperative complications (12% in ICA group vs. 9% in ECA group), wound infection (6% in ICA group vs. 7% in ECA group), or anastomotic leakage (6% in ICA group vs. 9% in ECA group). We did not observe a significant difference between the two groups in the number of lymph nodes collected (19.46 ± 7.06 in ICA group vs. 22.68 ± 8.79 in ECA group; p = 0.086). ICA following laparoscopic right hemicolectomy, compared to ECA, could lead to a significant improvement in bowel function recovery and a reduction in the length of hospital stay in RCC patients.

RESUMO

The incidence of colorectal cancer in kidney transplant recipients has been previously reported with conflicting results. In this study, we investigated if the incidence of colorectal advanced neoplasms in kidney transplant recipients, evaluated with screening colonoscopy, was higher than in healthy individuals. One-hundred sixty kidney transplant recipients undergoing screening colonoscopy were compared with 594 age- and sex-matched healthy individuals. Advanced colorectal neoplasia was found in 22 patients (13.7%), including four patients (2.5%) with colorectal cancer. Compared with the healthy population, kidney transplant recipients did not have an increased risk of developing a colorectal cancer (OR 0.69; 95% CI 0.236-2.063, p = 0.688) although it developed at a younger age. In contrast, kidney transplant recipients had a higher risk of developing an advanced adenoma compared with the control group (OR 1.65; 95% CI 0.930-2.981, p = 0.04). In conclusion, kidney transplant recipients did not have an increased incidence of colorectal cancer compared with healthy population. However, transplant patients displayed a higher incidence of colorectal adenomas, suggesting that screening colonoscopy in kidney transplant recipients should be expanded to include even younger recipients (<50 years old).

RESUMO

This study aims to systematically assess the efficacy of parenteral and oral antibiotic prophylaxis compared to parenteral-only prophylaxis for the prevention of surgical site infection (SSI) in patients undergoing laparoscopic surgery for colorectal cancer resection. Published and unpublished randomized clinical trials comparing the use of oral and parenteral prophylactic antibiotics vs. parenteral-only antibiotics in patients undergoing laparoscopic colorectal surgery were collected searching electronic databases (MEDLINE, CENTRAL, EMBASE, SCIENCE CITATION INDEX EXPANDED) without limits of date, language, or any other search filter. The outcomes included SSIs and other infectious and noninfectious postoperative complications. Risk of bias was assessed using the Cochrane revised tool for assessing risk of bias in randomized trials (RoB 2). A total of six studies involving 2252 patients were finally included, with 1126 cases in the oral and parenteral group and 1126 cases in the parenteral-only group. Meta-analysis results showed a statistically significant reduction of SSIs (OR 0.54, 95% CI 0.40 to 0.72; p < 0.0001) and anastomotic leakage (OR 0.55, 95% CI 0.33 to 0.91; p = 0.02) in the group of patients receiving oral antibiotics in addition to intravenous (IV) antibiotics compared to IV alone. Our meta-analysis shows that a combination of oral antibiotics and intravenous antibiotics significantly lowers the incidence of SSI compared with intravenous antibiotics alone.

RESUMO

INTRODUCTION: Abdominal pain (AP) is one of the most frequent clinical condition observed in elderly patients. The differential diagnosis is wide and definitive diagnosis is often difficult due to delayed symptoms, altered laboratory parameters, pre-existing medical disorders, abuse of drugs and in absence of an accurate medical history. EVIDENCE ACQUISITION: A systematic literature review was carried out through PubMed database for studies published in the last ten years. The following search string was used: {("geriatric"[Title] OR "older"[Title] OR "aged"[Title] OR "elderly"[Title]) AND ((("abdomen"[Title] AND "acute"[Title]) OR "acute abdomen"[Title] OR ("acute"[Title] AND "abdomen"[Title])) OR ("abdominal"[Title] AND "pain"[title]) OR "abdominal pain"[Title])}. Full articles and abstracts were included. Case reports, commentaries, editorials and letters were excluded from the analysis. EVIDENCE SYNTHESIS: As the age of people presenting AP advances, both rates of surgical procedures and mortality rate increase. CONCLUSIONS: A systematic approach based on the organization of differential diagnoses into categories, may provide a helpful framework by the combined use of history-taking, physical examination, and results of diagnostic studies. In elderly patients admitted to the emergency department, a crucial role is played by a prompt use of radiological investigations in order to discriminate between older subjects admitted to the emergency department with abdominal pain and pathological cases requiring immediate surgical treatment.
