The present study investigated the effects of COVID‑19 pandemic on clinical presentation and therapeutic management acute surgical abdomen. A retrospective emergency hospitalizations with a diagnosis abdomen between April July 2020 vs. similar period in 2019 was performed. observation sheets operating protocols were analyzed. Between 2020, 50 cases hospitalized treated, compared to 43 same last year. main types pathology both groups included: Occlusions (60%, respectively 44.2% 2019)...
Laparoscopic cholecystectomy (LC) is the gold standard treatment in acute cholecystitis. However, one six cases expected to be difficult due intense inflammation and suspected adherence involvement of adjacent important structures, which may predispose patients higher risk vascular biliary injuries. In this study, we aimed identify preoperative parameters with predictive value for surgical difficulties. A retrospective study 255 cholecystitis admitted emergency was performed between 2019...
This document replaces the DGP recommendations published in 1998 and 2013. Based on recent studies a consensus conference, indications, choice performance of adequate exercise testing method its necessary technical staffing setting are discussed. Detailed provided: for blood gas analysis right heart catheterization during exercise, walk tests, spiroergometry, stress echocardiography. The correct use different tests is discussed specific situations respiratory medicine: induced asthma,...
The idea of sensitivity in ant colony systems has been exploited hybrid ant-based models with promising results for many combinatorial optimization problems. Heterogeneity is induced the population by endowing individual ants a certain level to pheromone trail. variable within same can potentially intensify search while time inducing diversity exploration environment. performance sensitive investigated solving generalized vehicle routing problem. Numerical and comparisons are discussed...
The Building Block Hypothesis suggests that Genetic Algorithms (GAs) are well-suited for hierarchical problems, where efficient solving requires proper problem decomposition and assembly of solution from sub-solution with strong non-linear interdependencies. paper proposes a hill-climber operating over the building block (BB) space can efficiently address problems. new Hill-Climber (BBHC) uses hill-climb search experience to learn structure. neighborhood structure is adapted whenever...

One of the main issues in computational game theory is equilibria detection multi player games. This problem approached using a generative relation for strategy profiles and two different search operators: crowding based differential evolution simple stepping stone reinforcing algorithm. A probabilistic also derived order to tackle higher number players. Each approach has advantages disadvantages, illustrated by numerical experiments games involving from hundred
Infecţia cu Helicobacter pylori (H.pylori) reprezintă una dintre marile probleme de sănătate publică actuale, având incidenţă ridicată la nivel global.Această afecţiune se asociază alte patologii precum ulcerul peptic sau cancerul gastric, determinând o reală provocare pentru specialităţiile din domeniul medical.Am realizat un studiu retrospectiv ce include cohortă 275 pacienţi care au efectuat endoscopie digestivă superioară şi fost testaţi prezenţa infecţiei H. prin testul antigenului...
Melanoma is a malignant tumor that determines approximately 80% of deaths as skin cancer-related. The sentinel lymph node (SLN) represents the first filter cells toward systemic dissemination. primary objective was to outline surgical specifics biopsy (SLNB) technique, correlate location with radiotracer load, and identify characteristics older patients.In this prospective study, 122 cases melanoma needing SLNB technique were included, between June 2019 November 2022, resulting in 162 nodes...
Inguinal hernia repairs are one of the most common procedures in general surgery. In addition to classical open surgery, laparoscopic techniques, such as transabdominal preperitoneal (TAPP) and total extraperitoneal (TEP) repair, have gained acceptance increasingly used for inguinal repairs, these three techniques only standards repairs. This study aimed compare results adult patients using TAPP patch technique Lichtenstein regarding level pain perceived day after surgery number days...
Abstract This paper proposes a Fuzzy Divisive Hierarchical Clustering Algorithm (FDHC) for the optimal choice of sets solvents systems in thin layer chromatography. new approach described here is capable finding best system and combination two or more TLC according to, instance, quality partition coefficient (QP). In this order an IBM-PC computer has been used to run corresponding program written Pascal.
