[Results of analysis of the prescriptions for elderly patients in ambulatory practice.]

A randomized retrospective analysis of medical records of patients aged 65 years and older receiving ambulatory medical care was carried out in order to assess drug prescriptions for the detection of polypharmacy and potentially dangerous and significant drug interactions. The average number of visits per patient over 65 is 11,2±8,4. Comorbidity was detected in 89,4% of patients. Polypharmacy was detected in 76,6% of patients. In 1/3 of cases, patients were prescribed not recommended drugs (Beers criteria 2015). Authors found 364 interactions of various hazard categories. The obtained data shows that it is mandatory to implement various systems of prescription audit for the timely detection of potentially hazardous and incompatible drugs, as well as to correct prescriptions and improve efficacy and safety of drug use in patients older than 65 years.

Tracking T-cell immune reconstitution after TCRαß/CD19-depleted hematopoietic cells transplantation in children.

αßT-cell-depleted allogeneic hematopoietic cell transplantation holds promise for the safe and accessible therapy of both malignant and non-malignant blood disorders. Here we employed molecular barcoding normalized T-cell receptor (TCR) profiling to quantitatively track T-cell immune reconstitution after TCRαß-/CD19-depleted transplantation in children. We demonstrate that seemingly early reconstitution of αßT-cell counts 2 months after transplantation is based on only several hundred rapidly expanded clones originating from non-depleted graft cells. In further months, frequency of these hyperexpanded clones declines, and after 1 year the observed T-cell counts and TCRß diversity are mostly provided by the newly produced T cells. We also demonstrate that high TCRß diversity at day 60 observed for some of the patients is determined by recipient T cells and intrathymic progenitors that survived conditioning regimen. Our results indicate that further efforts on optimization of TCRαß-/CD19-depleted transplantation protocols should be directed toward providing more efficient T-cell defense in the first months after transplantation.

[Arterial blood pressure in persons of elderly, senile age and long-livers of Yakutsk: population screening].

The values of arterial blood pressure according to the Yakutsk population screening at the age of 60 and older have been studied. The average values of systolic arterial pressure (both sexes--148, men--145, women--151 mm Hg) are higher than normal values specified by Society of Cardiology of Russian Federation. Long-living persons show its decrease that is more marked in men. The average values of diastolic arterial pressure (both sexes--87, men--88, women--87 mm Hg) correspond to the category of high normal pressure and are decreasing with age to more extent in men than in women. The average values of pulse pressure in elderly and senile age are higher than normal values (both sexes--61, men--57, women--64 mm Hg) with a tendency to grow by 90 years old. Differences in arterial blood pressure levels are educed in gerontic persons depending on presence of abdominal obesity, hypercholesterolemia, hyperglycemia, smoking and family anamnesis with cases of hypertension.

[Features of arterial blood pressure in elderly persons of different ethnic groups in Yakutsk].

The differences in arterial blood pressure in the sample of population in the age of 60 and older of different ethnic groups in Yakutsk, as well as its connection with the other cardiovascular diseases risk factors have been analyzed. It was shown that the average values of systolic and diastolic blood pressure in subsample of the Yakuts appeared to be lower than in Caucasoid gerontic persons. The average values of systolic arterial blood pressure both in the Yakuts and in the Caucasoids were detected higher than normal values in all age-dependent subgroups. The average values of diastolic blood pressure in both ethnic groups were within the limits of high normal level. From 60 to 90 years and older the decrease in systolic and diastolic arterial blood pressure was detected; it was more marked in Caucasoid gerontic persons. The average values of pulse pressure in the Yakuts and in the Caucasoids appeared to be higher than the existing standard and didn't have any differences in ethnic groups. In both ethnical subsamples, pulse pressure values increase was observed in persons of 60-89 years old and its decrease after 90. Persons with overweight, obesity, central (abdominal) obesity, dyslypoproteidemias irrespective of belonging to ethnical group were characterized as having higher levels of arterial blood pressure. Statistically significant differences in the levels of arterial blood pressure in the Yakuts and in the Caucasoids depending on hyperglycemia, smoking, the presence of burdened anamnesis, educational level, marital status was not detected.

[Prevalence of atrophic gastritis in different populations in Siberia on medical evidence of the serological survey].

Prevalence of atrophic gastritis in various population of Siberia with serological tests was studied. Representative samples of Novosibirsk adult population and also urban and rural population of Yakutia were examined. 348 persons at the age more than 45 years (180 males and 168 females) were studied. Concentration of pepsinogen I, gastrin 17 and antibodies to Helicobacter pilori in blood serum was estimated with immune-enzyme analysis ("Biohit GastroPanel", "Biohit", Finland). In addition, domestic test-systems were used for detection cytotoxic (expressing CagA-protein) strains H. pylori. Level of markers (pepsinogen, gastrin, antibodies to Helicobacter pilori and antibodies to CagA H. pilori) in observing populations had no difference between males and females, and also did not depend on age. Occurrence of atrophy in body of stomach in Novosibirsk population, urban and rural population of Yakutia was 10.1, 16.7 and 25.6% respectively, and in antral part--10.7, 25.6 and 8.9% respectively. Total atrophy was registered in 1% in all groups. Helicobacter infection was detected in 78-88% of population. Domestic immune-enzyme test-systems were comparable with data of histological examination and demonstrated greater sensitivity at H. pylori detection vs. foreign. High prevalence of atrophic gastritis in various groups of Siberia population was noticed, which must be was bounded with great level of H. pylori infection in population.
