Enhanced Recovery After Surgery protocol in colorectal surgery allows shortening length of hospital stay and reducing complication rate. Despite the clear guidelines and conclusive evidence their full implementation and putting them into daily practice meets certain difficulties, especially in the early stage. The aim of the study was to analyse the course of implementation of the ERAS protocol into daily practice on the basis of adherence to the protocol. Group included 92 patients (43F/49M) with colorectal cancer submitted to laparoscopic resection during the years 2013-2014. Perioperative care in all of them based on ERAS protocol consisting of 16 items. Its principles and discharge criteria were based on the guidelines of the ERAS Society guidelines. The entire analysed group of patients was divided into 3 subgroups (30 patients) depending on the time from ERAS protocol implementation. We analysed the compliance with the protocol and its influence on length of hospital stay, postoperative complications and readmission rate in different subgroups. The average compliance with the protocol differed significantly between groups and was 65% in group 1, 83.9% in group 2 and 89.6% in group 3. The compliance with subsequent protocol elements was different. The length of stay and complication rate was statistically different in analysed subgroups. The whole group demonstrated an inverse correlation between compliance and length of stay. This analysis leads to the conclusion that the introduction of the ERAS protocol is a gradual process, and its compliance at the level of 80% or more requires at least 30 patients and the period of about 6 months. The initial derogation from the assumed proceedings is inevitable and should not discourage further action. Particular emphasis in the initial stage should be put on continuous training of personnel of all specialties and continuous evaluation of the results.

Introduction and PurposeMorbid obesity together with obesity-related diseases has a negative impact on the quality of life. The aim of the study was to assess the quality of life amongst patients with morbid obesity as well as the impact of bariatric treatment on body weight and obesity-related diseases in addition to conducting an analysis of changes in the quality of life after surgical treatments, in the context of the surgical procedure type and degree of body weight loss.Material and MethodsSixty-five patients were treated for morbid obesity. The sample group consisted of 34 patients treated with laparoscopic sleeve gastrectomy (LSG) and 31 persons qualified for laparoscopic Roux-en-Y gastric bypass (LRYGB). The average body weight before the procedure was 146.2 kg. In the sample group, 89 % of persons qualified for the surgical treatments were diagnosed with hypertension and 52 % persons that were operated on were diagnosed with diabetes type 2 before the surgical procedure. Before commencement of the surgical treatment, the quality of life was assessed, which in both groups qualified for given types of bariatric procedures was considerably low.Results and ConclusionsPercentage excessive weight loss (%EWL) was 58.8 %. No significant differences in body weight loss were noted between the two types of procedures. Improvement was observed in the treatment of obesity-related diseases. Also, the quality of life was enhanced significantly. No differences were noted in terms of the quality of life improvement between particular types of surgical procedures. No significant differences were observed during the analysis of body weight loss impact on the quality of life improvement.

Summary Background 80% of individuals with cancer will require a surgical procedure, yet little comparative data exist on early outcomes in low-income and middle-income countries (LMICs). We compared postoperative outcomes in breast, colorectal, and gastric cancer surgery in hospitals worldwide, focusing on the effect of disease stage and complications on postoperative mortality. Methods This was a multicentre, international prospective cohort study of consecutive adult patients undergoing surgery for primary breast, colorectal, or gastric cancer requiring a skin incision done under general or neuraxial anaesthesia. The primary outcome was death or major complication within 30 days of surgery. Multilevel logistic regression determined relationships within three-level nested models of patients within hospitals and countries. Hospital-level infrastructure effects were explored with three-way mediation analyses. This study was registered with ClinicalTrials.gov , NCT03471494 . Findings Between April 1, 2018, and Jan 31, 2019, we enrolled 15 958 patients from 428 hospitals in 82 countries (high income 9106 patients, 31 countries; upper-middle income 2721 patients, 23 countries; or lower-middle income 4131 patients, 28 countries). Patients in LMICs presented with more advanced disease compared with patients in high-income countries. 30-day mortality was higher for gastric cancer in low-income or lower-middle-income countries (adjusted odds ratio 3·72, 95% CI 1·70–8·16) and for colorectal cancer in low-income or lower-middle-income countries (4·59, 2·39–8·80) and upper-middle-income countries (2·06, 1·11–3·83). No difference in 30-day mortality was seen in breast cancer. The proportion of patients who died after a major complication was greatest in low-income or lower-middle-income countries (6·15, 3·26–11·59) and upper-middle-income countries (3·89, 2·08–7·29). Postoperative death after complications was partly explained by patient factors (60%) and partly by hospital or country (40%). The absence of consistently available postoperative care facilities was associated with seven to 10 more deaths per 100 major complications in LMICs. Cancer stage alone explained little of the early variation in mortality or postoperative complications. Interpretation Higher levels of mortality after cancer surgery in LMICs was not fully explained by later presentation of disease. The capacity to rescue patients from surgical complications is a tangible opportunity for meaningful intervention. Early death after cancer surgery might be reduced by policies focusing on strengthening perioperative care systems to detect and intervene in common complications.

Numerous scientific studies confirm that, apart from environmental and genetic factors, a significant role is played by gastrointestinal microbiota in the aetiology of type 2 diabetes and obesity. Currently, scientists mainly focus on the distal intestinal microbiota, while the equally important proximal parts of the intestine are overlooked. The aim of the study was a qualitative analysis of the structure of the duodenal mucosa microbiota in groups of patients with obesity and with type 2 diabetes and where obesity qualified for bariatric surgery: sleeve gastrectomy. The microbiological results obtained were compared with some clinical parameters. As a result, it was possible to determine the microbiological core that the treatment and control groups had in common, including phyla: Firmicutes, Proteobacteria, and Actinobacteria. The patients with obesity and with type 2 diabetes and obesity presented a significantly lower number of genus Bifidobacterium compared to healthy subjects. Furthermore, the numbers of Bifidobacterium were positively correlated with the high density lipoprotein (HDL) concentration in the groups under study. The obtained results indicate that bacteria of the genus Bifidobacterium should be considered in the future in the context of a potential biomarker in the progress of type 2 diabetes and obesity.

Relativistic multiconfiguration Dirac - Fock (MCDF) transition energies and oscillator strengths are determined in an `optimal level' scheme for both the spin-allowed - and spin-forbidden 3 - transitions in the magnesium isoelectronic sequence through . The modest relativistic configuration mixing to represent the intravalence correlation is combined in MCDF calculations with a polarization model to account for valence - core electron correlation. For the first few members of the sequence (Mg I to Cl VI) rather extensive relativistic configuration interaction Dirac - Fock (CIDF) calculations (with and without core polarization) are also performed to improve the representation of the intravalence electron correlation which is important for the neutral end of the sequence. The influence of the intravalence correlation, as well as the valence - core electron correlation on oscillator strengths, excitation energies and ionization energies is investigated. The proper representation of the intravalence electron correlation is found to be crucial for oscillator strength calculations near the neutral end of the magnesium isoelectronic sequence. For some elements of the sequence the present data are the only ones available.
