Gender peculiarities of gastroesophageal reflux disease

We studied gender-specific clinical manifestations and risk factors for gastroesophageal reflux disease (GERD) in the urban population of Ulan-Ude. The study included 352 patients with GERD. It was found that in both sexes prevailed not erosive reflux disease. It was detected in 64,2% of men and in 88% of women (p = 0,005). Men significantly more often had severe forms of the disease: erosive esophagitis - 19,8% more often than in women (p = 0,04), in 2,9% of men we revealed esophageal ulcers, in 1,1% - Barrett esophagus, while the in women didn't have these forms of the disease. Daily repeated heartburn was found in women twice more often than in men. Average grade of GERD-Q questionnaire for women was also significantly higher than for men by 19% (p = 0,04). Women had higher levels of anxiety and depression (average grade on BDI was higher by 29% than in men). Men had significantly more frequently such risk factors as smoking, alcohol intake and women more often had diabetes, hypertension and coronary heart disease

Neuropathic pain

Background Chronic neuropathic pain is a common occurrence, its prevalence ranges from 7 to 10% of the total population. Currently, the only official document that includes neuropathic pain is the International Classification of Headaches Disorders (ICHD-3), in which this type of pain is associated with traumatic brain injury and neuralgia. Until now, there has been no generally accepted terminology and classification of chronic neuropathic pain.Objective To provide the current terminology, classification and additional characteristics of neuropathic chronic pain.Results The review of modern terminology and classification of neuropathic chronic pain describes the terms included in the concept of chronic peripheral and central neuropathic pain, identifies pain subtypes, as well as its additional characteristics such as the intensity of neuropathic pain, the severity of suffering and disability.Conclusions Thus, the presented recent classification of chronic neuropathic pain is an exhaustive list of the most common neuropathic pain syndromes. The inclusion of classification into clinical practice will help to draw attention to the problem of treatment of chronic neuropathic pain by WHO members, carrying out epidemiological studies and making a correct diagnosis, and therefore the appointment of adequate treatment methods

RISK FACTORS FOR EXTRAESOPHAGEAL SYMPTOMS OF GASTROESOPHAGEAL REFLUX DISEASE

The aim of the study was to investigate the frequency and nature of extraesophageal symptoms in patients with gastroesophageal reflux disease. 122 patients with GERD without comorbidity have been examined (58 males, 64 females). The anthropometrical survey has been performed; estimated age, duration of the disease and smoking have been taken into account. Extraesophageal symptoms were diagnosed with the rabeprazole test, the frequency and intensity of the symptoms were evaluated using a Likert scale. All patients underwent endoscopic examination and the assessment of quality of life by means of the SF-36 questionnaire. Extraesophageal symptoms of GERD were diagnosed in 38 (31.1 %) patients, reflux laryngitis - in 14 (9.8 %) patients, reflux-pharyngitis - in 7 (4.1 %) patients, reflux cough - in 11 (7.3 %) patients, heart pain - in 6 (3.2 %) patients. In patients with extraesophageal manifestations compared with the patients having only physical symptoms, body mass index and the severity of heartburn on the Likert scale were significantly higher. Other indicators, such as disease duration, smoking, presence of erosive changes in the mucous membrane of the esophagus, hernia hiatal didn't statistically reveal any difference between the groups. When comparing the quality of life it has been revealed that the indicators of physical health had no statistical difference in the two groups, when mental health indices were lower in those with extraesophageal symptoms of GERD

CHANGES IN THE LEVEL OF NT-proBNP AND MEAN PULMONARY ARTERY PRESSURE FOLLOWING BRONCHOPLASTIC LOBECTOMY OR PNEUMONECTOMY AS MARKERS OF RIGHT VENTRICULAR DYSFUNCTION

Background There are scanty data of right ventricular dysfunction markers after major pulmonary resection.Objective To study the changes of plasma level of N-terminal pro-brain natriuretic peptide (NT-proBNP) and its association with pulmonary artery pressure (PAP) as markers of right ventricular dysfunction in patients who underwent bronchoplastic lobectomy or pneumonectomy.Material and Methods The study population consisted of 36 patients aged 40–65 who underwent major  pulmonary resection for lung cancer in 2016–2018. Patients were stratified into two groups according to the type of surgical procedure: bronchoplastic lobectomy, the main group (n = 19), and pneumonectomy, control group (n = 17). They were then analyzed for plasma NT-proBNP concentration, operative time, blood loss, intraoperative fluid administration, intraoperative urine output, and mean PAP level before and after an operation.Results The mean PAP level correlated positively with the plasma NT-proBNP concentration in the pneumonectomy group (Pearson r = 0.916754; p < 0.001). This correlation was no evident in the subset of patients undergoing bronchoplastic lobectomy at the same determination point (Pearson r = 0.234741; p = 0.330).Conclusion The mean PAP increased significantly after pneumonectomy and is closely correlated with plasma  NTproBNP concentration. These findings support the conclusion that bronchoplasty is preferable over pneumonectomy for lung cancer patients

Effect of High-Pressure Torsion on the Microstructure and Magnetic Properties of Nanocrystalline CoCrFeNiGax (x = 0.5, 1.0) High Entropy Alloys

In our search for an optimum soft magnet with excellent mechanical properties which can be used in applications centered around “electro mobility”, nanocrystalline CoCrFeNiGax (x = 0.5, 1.0) bulk high entropy alloys (HEA) were successfully produced by spark plasma sintering (SPS) at 1073 K of HEA powders produced by high energy ball milling (HEBM). SPS of non-equiatomic CoCrFeNiGa₀.₅ particles results in the formation of a single-phase fcc bulk HEA, while for the equiatomic CoCrFeNiGa composition a mixture of bcc and fcc phases was found. For both compositions SEM/EDX analysis showed a predominant uniform distribution of the elements with only a small number of Cr-rich precipitates. High pressure torsion (HPT) of the bulk samples led to an increased homogeneity and a grain refinement: i.e., the crystallite size of the single fcc phase of CoCrFeNiGa₀.₅ decreased by a factor of 3; the crystallite size of the bcc and fcc phases of CoCrFeNiGa—by a factor of 4 and 10, respectively. The lattice strains substantially increased by nearly the same extent. After HPT the saturation magnetization (Ms) of the fcc phase of CoCrFeNiGa₀.₅ and its Curie temperature increased by 17% (up to 35 Am²/kg) and 31.5% (from 95 K to 125 K), respectively, whereas the coercivity decreased by a factor of 6. The overall Ms of the equiatomic CoCrFeNiGa decreased by 34% and 55% at 10 K and 300 K, respectively. At the same time the coercivity of CoCrFeNiGa increased by 50%. The HPT treatment of SPS-consolidated HEAs increased the Vickers hardness (Hv) by a factor of two (up to 5.632 ± 0.188) only for the non-equiatomic CoCrFeNiGa₀.₅, while for the equiatomic composition, the Hv remained unchanged (6.343–6.425 GPa)
