The complex problem of the operated stomach has recently attracted more and more attention of therapists, surgeons and radiologists. Systematic X-ray examination of the stomach, after surgery, gives us the opportunity to study its shape and function, allows us to judge the success of the operation, as well as to recognize timely postoperative complications and recurrence of diseases, requiring in some cases urgent secondary surgical intervention, and in other cases - prevention of unnecessary secondary surgery.

The decisive method for the treatment of malignant neoplasms of the stomach is surgical intervention. The successes achieved in this direction are limited mainly to surgery for primary cancer of the stomach. Patients with recurrent tumors in the stomach stump, as well as with secondary malignant neoplasms in this area after surgery for peptic ulcer, polyps and other diseases, were considered doomed and hopeless until recently.

IntroductionAfter a long period of anticipation,1 the last two years have witnessed the first high-resolution x-ray structures of fragments from fibrinogen and fibrin.2-7 The results confirmed many aspects of fibrinogen structure and function that had previously been inferred from electron microscopy and biochemistry and revealed some unexpected features. Several matters have remained stubbornly unsettled, however, and much more work remains to be done. Here, we review several of the most significant findings that have accompanied the new x-ray structures and discuss some of the problems of the fibrinogen-fibrin conversion that remain unresolved. * Abbreviations: GPR—Gly-Pro-Arg-derivatives; GPRPam—Gly-Pro-Arg-Pro-amide; GHRPam—Gly-His-Arg-Pro-amide

Colonic Diverticular Disease

AbstractThe modern management of colonic diverticular disease involves grouping patients into uncomplicated or complicated diverticulitis, after which the correct treatment paradigm is instituted. Recent controversies suggest overlap in management strategies between these two groups. While most reports still support surgical intervention for the treatment of complicated diverticular disease, more data are forthcoming suggesting complicated diverticulitis does not merit surgical resection in all scenarios. Given the significant risk for complication in surgery for diverticulitis, careful attention should be paid to patient and procedure selection. Here, we define complicated diverticulitis, discuss options for surgical intervention, and explain strategies for avoiding operative pitfalls that result in early and late postoperative complications.

Probability Prediction

Aim: The purpose of the study is the development and evaluation of the informativeness of the author’s 3D nephrometric score application to predict the probability of intraoperative and postoperative complications in kidney operations. Material and methods: The study includes 264 patients who underwent surgical treatment of renal tumors, before that CT and 3D modeling were carried out. All patients underwent an analysis of the surgical intervention complexity on the C-index, PADUA, R.E.N.A.L., and developed 3D nephrometric score. To determine the set of variables that allow to classify patients, the method of discriminant analysis was used to predict the nature, volume of blood loss, duration of ischemia, and the number of complications. The sensitivity and specificity of the predictors were estimated with the help of ROC analysis. Results: Indicators have been established to classify patients according to the probability of complications, the amount of blood loss and the duration of ischemia during surgery for kidney cancer. We have created linear models that predict the development of bleeding during surgery, the volume of blood loss of more than 200 ml and the duration of ischemia more than 20 min, as well as the likelihood of complications using discriminant functions. The proposed author’s nephrometric score exceeds the capabilities of C-index, PADUA, R.E.N.A.L in many ways in blood loss and time of ischemia predicting, which allows us to recommend it for the assessment of resectability in kidney operations.

SUMMARY Current X-ray diffraction and cryoelectron microscopic data of ribosomes of eubacteria have shed considerable light on the molecular mechanisms of translation. Structural studies of the protein factors that activate ribosomes also point to many common features in the primary sequence and tertiary structure of these proteins. The reconstitution of the complex apparatus of translation has also revealed new information important to the mechanisms. Surprisingly, the latter approach has uncovered a number of proteins whose sequence and/or structure and function are conserved in all cells, indicating that the mechanisms are indeed conserved. The possible mechanisms of a new initiation factor and two elongation factors are discussed in this context.

Objective: To assess the efficacy of hemorrhoidectomy with Milligan-Morgan technique in the author’s modification.Methods: Results of surgical treatment of 558 patients aged 21–72 years with complicated hemorrhoids of III–IV stage were analyzed. The group of clinical comparison (207 patients) was operated according to standard scheme, the main group (351 patients) – according to author’s technology with modified technique for treating the hemorrhoid bolus using betamethasone.Results: When using the author’s technique, a more significant decrease in postoperative pain syndrome severity was achieved: injection analgesics were not required already in a day, and after 6 days the pain syndrome was stopped in all cases. Only three patients (0.9%) demonstrated an acute urinary retention up to two days. The group of clinical comparison maintained a longterm (up to three months) pain syndrome; postoperative urinary retention was registered in 38 cases (18.4%); 9 patients (4.3%) developed blood loss in the area of surgical intervention.Conclusions: Suggested technique of surgical treatment for hemorrhoids is quite effective, simple and can be implemented in any surgical inpatient facility.

ABSTRACT BACKGROUND: Hip fractures are one of the leading causes of disability and dependency among the elderly. The rate of hip fractures has been progressively increasing due to the continuing increase in average life expectancy. Surgical intervention is the mainstay of treatment, but with an increasing prevalence of comorbid conditions and decreased functional capacity in elderly patients, more patients are prone to postoperative complications. OBJECTIVES: Assess the value of surgical intervention for hip fractures among the elderly by quantifying the 1-year mortality rate and assessing factors associated with mortality. DESIGN: Medical record review. SETTING: Tertiary care center. PATIENTS AND METHODS: All patients 60 years of age or older who sustained a hip fracture between the period of 2008 to 2018 in a single tertiary healthcare center. Data was obtained from case files, using both electronic and paper files. MAIN OUTCOME MEASURES: The 1-year mortality rate for hip fracture, postoperative complications and factors associated with mortality. SAMPLE SIZE: 802 patients. RESULTS: The majority of patients underwent surgical intervention (93%). Intra- and postoperative complications were 3% and 16%, respectively. Four percent of the sample died within 30 days, and 11% died within one year. In a multivariate analysis, an increased risk of 1-year mortality was associated with neck of femur fractures and postoperative complications ( P =.034, <.001, respectively) CONCLUSION: The 1-year mortality risk in our study reinforces the importance of aggressive surgical intervention for hip fractures. LIMITATION: Single-centered study. CONFLICT OF INTEREST: None.

Chemotactic Ability

Detection of chemical stimuli is crucial for living systems and also contributes to quality of life in humans. Since loss of olfaction becomes more prevalent with aging, longer life expectancies have fueled interest in understanding the molecular mechanisms behind the development and maintenance of chemical sensing. Planarian flatworms possess an unsurpassed ability for stem cell-driven regeneration that allows them to restore any damaged or removed part of their bodies. This includes anteriorly-positioned lateral flaps known as auricles, which have long been thought to play a central role in chemotaxis. The contribution of auricles to the detection of positive chemical stimuli was tested in this study using Girardia dorotocephala, a North American planarian species known for its morphologically prominent auricles. Behavioral experiments staged under laboratory conditions revealed that removal of auricles by amputation leads to a significant decrease in the ability of planarians to find food. However, full chemotactic capacity is observed as early as 2 days post-amputation, which is days prior from restoration of auricle morphology, but correlative with accumulation of ciliated cells in the position of auricle regeneration. Planarians subjected to x-ray irradiation prior to auricle amputation were unable to restore auricle morphology, but were still able to restore chemotactic capacity. These results indicate that although regeneration of auricle morphology requires stem cells, some restoration of chemotactic ability can still be achieved in the absence of normal auricle morphology, corroborating with the initial observation that chemotactic success is reestablished 2-days post-amputation in our assays. Transcriptome profiles of excised auricles were obtained to facilitate molecular characterization of these structures, as well as the identification of genes that contribute to chemotaxis and auricle development. A significant overlap was found between genes with preferential expression in auricles of G. dorotocephala and genes with reduced expression upon SoxB1 knockdown in Schmidtea mediterranea, suggesting that SoxB1 has a conserved role in regulating auricle development and function. Models that distinguish between possible contributions to chemotactic behavior obtained from cellular composition, as compared to anatomical morphology of the auricles, are discussed.

Aneurysm Repair

EVAR (endovascular aneurism repair) is the preferred method for the surgical treatment of ananeurysm. The advantage of this type of surgical intervention is that a smaller number of postoperative complications will occur. The main diagnostic tasks for patients after EVAR are to determine the size of the aneurysmal sac, detection of an endoleak, detection of the endoprosthesis migration and the deformation of the stent graft itself. Conclusion: early detection of complications in the postoperative period remains the main problem for monitoring patients after EVAR. Duplex scanning is a safe, non-invasive and effective method of measuring the size of an aneurysmal sac and detecting possible complications after EVAR.
