Aim. To assess the effect of intermittent hypoxic-hyperoxic exposures (IHHE) on the outcomes of on-pump cardiac surgery.Material and methods. This prospective, single-center, randomized, controlled study was conducted in 110 patients with heart valve defects and/or aortic pathology from the cardiac surgery clinic of the I. M. Sechenov First Moscow State Medical University. The total sample was randomly divided into a group of patients who underwent IHHE (n=66) and a control group of patients who underwent placebo procedures with ambient air (n=44). The frequency and structure of intra-and postoperative complications were analyzed within 30 days after surgery. The presence of cognitive impairment, as well as serum troponin I and lactate concentrations were analyzed before and after surgery.Results. Peri- and early postoperative complications such as cardiac death, non-fatal infarction and acute heart failure occurred significantly less frequently in patients treated with IHHE compared with placebo group (1,6% vs 16,7%, p=0,009; 1,6% vs 16,7%, p=0,009; 6,3% vs 33,3%, p<0,001, respectively). The median troponin I values 24 hours after surgery were 1,068 ng/ml (0,388-1,397 ng/ml) in the IHHE group and were significantly lower compared to the control group (1,980 ng/ml (1,068-3,239 ng/ml)). The serum lactate level after surgery was 1,8±0,7 mmol/l in the IHHE group and was significantly lower compared to the control group — 2,4±1,2 (p=0,05). Cognitive function, assessed by MOCA and MMSE tests, turned out to be significantly higher in patients who underwent a preoperative IHHE. No significant complications or serious adverse events were observed during the IHHE procedures.Conclusion. The use of individually adapted hypoxic preconditioning procedures reduces the incidence of peri- and postoperative complications, which is accompanied by a lower ischemia-reperfusion myocardial injury during artificial circulation with preservation of cognitive functions. IHHE procedures ramp up prehabilitation of patients referred for on-pump surgery of heart defects and aortic pathology.

Authors: Bokovikov I. F. , Protasov K. V. 
Published: August 2024

Aim. To assess the value of cellular indices of systemic inflammation in the prognosis of in-hospital mortality in patients with ST-segment elevation myocardial infarction (MI) in combination with type 2 diabetes (T2D).Material and methods. The retrospective case-control study included 125 patients with myocardial infarction and T2D, 25 of whom died during the index hospitalization. The cellular composition of the blood and the level of high-sensitivity C-reactive protein (hsCRP) were determined on the first and third days of hospitalization. In the groups of deceased and surviving patients, cellular indices of systemic inflammation were calculated and compared (neutrophil-lymphocyte ratio (NLR), neutrophil-monocyte ratio (NMR), monocyte-lymphocyte ratio (MLR), platelet-lymphocyte ratio (PLR), systemic inflammation index (SII), systemic inflammation response index (SIRI)) and average hsCRP levels). The prognostic role of the studied parameters was assessed using univariate and multivariate logistic regression.Results. Deceased patients, compared with survived ones, had higher Killip class, body mass index, number of stents implanted, higher hsCRP levels, and lower left ventricular ejection fraction. Inhospital mortality was associated with hsCRP (odds ratio of 1,03 with 95% confidence interval of 1,003-1,05, p=0,029), NLR (2,56 [1,73-9,78], p<0,001), NMR (1,16 [1,001-1,35], p=0,04), MLR (23,7 [3,1-182,6], p=0,002), SII (1,001 [1,0-1,001], p=0,028), SIRI (1,29 [1,09-1,52], p=0,003) 48 hours after admission, as well as with the degree of hsCRP change (1,03 [1,003-1,05], p=0,025), NLR (1,58 [1,21-2,06], p=0,001), SII (1,001 [1,0-1,001], p=0,028) during the first three days. Adjusted multivariate regression analysis identified a set of independent predictors with greatest accuracy in assessing the death probability: NLR, SII and SIRI 48 hours after admission, the degree of hsCRP change, body mass index and the num ber of implanted stents.Conclusion. The work demonstrated the significance of cellular indices of systemic inflammation (NLR, SII and SIRI) in assessing the prognosis of in-hospital mortality in patients with MI combined with T2D.

Published: August 2024

Objectives. This study aimed to experimentally identify and evaluate the effectiveness of using intensive interval programs to develop endurance in the educational process of 10-year-old boys.
Materials and methods. The research involved twenty 10-year-old boys. Control (n = 10) and experimental (n = 10) groups were created. Children and their parents were informed of the features of the study and agreed to participate in the experiment. The study protocol was approved by the ethics committee of H.S. Skovoroda Kharkiv National Pedagogical University (Kharkiv, Ukraine). This study was conducted in accordance with the Declaration of Helsinki – Ethical Principles for Medical Research Involving Human Subjects (World Medical Association Declaration of Helsinki, 2013). The following research methods were used: scientific and methodological literature analysis, pedagogical testing, and mathematical statistics to process research results.
Results. According to the results of the complex control of boys’ endurance abilities, statistically significant changes in all indicators in both experimental (p < 0.001) and control groups (p < 0.05) were established. The positive dynamics of the results favoured the experimental group.
The most statistically significant changes took place in the experimental group on indicators of tests “Push-ups in a lying position” by 35.2% (p < 0.001), “Jumping with a rope for 1 min” (20.8%; p < 0.001), “Squatting on two legs for 1 min” (18.8%; p < 0.001), “From a lying position rising in a saddle for 1 min” (17.4%; p < 0.01). The obtained results of the final testing in tests “Hanging on bent arms’ ”, “Burpee test in 1 min” and “300 m run” were somewhat lower and still demonstrated statistically significant changes (13.0%, 11.4%, 6.5%, respectively, at the level of significance p < 0.001). General endurance developed more slowly than other types of endurance. In “Hanging on bent arms’ ” the change in data after the experiment in the control group was statistically insignificant (p = 0.05).
Conclusions. The intensive interval training method, which used specially selected exercises according to the “Tabata Protocol,” promoted endurance development in 10-year-old boys.

Background: Cholera is a major public health concern which is caused by Vibrio cholerae, found in freshwater, sewage and clinical reservoirs. The Water and Sanitation Agency (WASA) maintains water supply and sewerage services in Lahore, Pakistan. This study aimed to isolate V. cholera from sewage managed by WASA and to evaluate the awareness and sociodemographic factors linked to V. cholerae isolation and cholera awareness in Lahore residents.
Methods: A cross-sectional study was conducted on 100 sewerage sample from 8 towns of Lahore to isolate V. cholera. 300 individuals each representing 01 household were interviewed to assess the level of knowledge, attitude and practice regarding cholera. Sewerage samples were analyzed using the TCBS agar and Oxidase test. The serotype of positive samples was found using antisera.
Results: V. cholera (serotype O1) was isolated from 2 out of 100 sewerage samples from 2 out of 8 towns of Lahore. In areas where V. cholera was detected the average score of knowledge, attitude and practice among the residents was less as compared to the areas where it was not detected. The history of acute watery diarrhea among household was statistically significant in areas where V. cholera was detected (p value 0.044).
Conclusion: The isolation and the detection of V. cholera serotype O1 signifies the fact that V. cholera is present in Lahore. The residents of the area where V. cholera was detected had low level of knowledge, attitude and practice as compared to the areas where it was not detected.

El presente estudio tuvo como objetivo analizar el efecto de una intervención nutricional en la glucosa, índice de masa corporal (IMC) y circunferencia de cintura (CC) en pacientes con diabetes mellitus tipo 2 (DM2). Se realizó un estudio cuasiexperimental en 24 pacientes del sureste de México diagnosticados con DM2, de los cuales 12 recibieron una intervención nutricional, que consistió en asesoría dietética personalizada durante un periodo de 7 meses, mientras que los otros 12 formaron el grupo control y solo recibieron tratamiento farmacológico estándar. Se observó un cambio positivo en el IMC del grupo de intervención, respecto al control. Además, hubo una reducción significativa en todas las variables medidas (glucosa, IMC y CC) dentro del grupo de intervención al comparar los valores al inicio y al final del periodo del estudio. Los hallazgos sugieren que las intervenciones nutricionales pueden ser una estrategia efectiva para mejorar el estado de salud física y reducir los niveles de glucosa en pacientes con DM2 siempre y cuando exista una adecuada adherencia al tratamiento farmacológico.
The aim of this study was to analyze the effect of a nutritional intervention on glucose, body mass index (BMI), and waist circumference (WC) in patients with type 2 diabetes mellitus (T2DM). A quasi-experimental study was conducted on 24 patients from southeastern Mexico diagnosed with T2DM, of which 12 received a nutritional intervention consisting of personalized dietary counseling over a period of 7 months, while the other 12 formed the control group and only received standard pharmacological treatment. A positive change in BMI was observed in the intervention group compared to the control group. Additionally, there was a significant reduction in all measured variables (glucose, BMI, and WC) within the intervention group when comparing values at the beginning and end of the study period. The findings suggest that nutritional interventions can be an effective strategy to improve physical health and reduce glucose levels in patients with T2DM, provided there is adequate adherence to pharmacological treatment.
