OBJECTIVE. Evaluating according to laboratory tests the effectiveness of Liasten in the treatment of patients with multidrug-resistant pulmonary tuberculosis (MDR-TB). MATERIALS AND METHODS. Evaluation of the effectiveness of etiotropic and etiopathogenetic therapy in 57 patients with MDR-TB was performed. According to the treatment schemes, patients were divided into groups. The control group (n=22) received individualized antimycobacterial therapy (AMBT) regimens. The experimental group (n=35) received AMBT in combination with Liasten. Evaluation of the effectiveness of treatment regimens was performed on the basis of indicators of general clinical blood tests, immunological and bacteriological studies. RESULTS AND DISCUSSION. In patients of the experimental group, compared with the control in 1.5 times more often found positive changes in the hemogram of blood and ESR (p<0.05-0.001), the establishment of a dynamic balance between the pools of lymphocyte cells CD4+ and СD8+ (immunoregulatory index, p<0.05), an increase in the number of phagocytosis active cells (phagocytic index, p<0.05), the content of cationic lysosomal proteins of granulocyte leukocytes (p<0.05), a 1.4-fold decrease in the cytochemical coefficient of neutrophils (p<0.05), the number of proliferated under the action of PPD-L lymphocytes (p<0.05), normalization of phagocytic counts and total redox activity of neutrophils (p<0.05), increase in frequency and reduction of anesthesia was stated. CONCLUSIONS. Restoration of the body’s immune status, blood hemogram, increase in frequency and reduction of the time of decontamination were more active and occurred 1.5 times more often in patients receiving a complex combination of AMBT with Liasten.

AbstractThe result of improper treatment has led to the rise of Multidrug-resistant (MDR) strains. This concern still exists in Pakistan. In order to save energy, time and resources an early detection of resistant cases is imperative. Thus, a treated group of 100 isolates and a control group of 56 untreated isolates were studied. PCR and gene sequencing showed mutations at codon 531 and 513 in the rpoB gene. 12% of cases showed a double mutation in the rpoB gene. katG gene showed mutations at codon 315 and 299. 28.6% of the control group cases were positive for MDR whereas 100% of the treated group were positive for MDR. This study explores the significantly increasing ratio of MDR-TB among Pakistani population. This study provides prevalent MDR mutations among Pakistanis and suggests developing such molecular assays that are time and cost effective. Importance: Pakistan is a developing country and has fourth highest incidence rate of MDR-TB. The treatment of MDR-TB is the use of second line drugs that has severe side effects as well as it requires long time span. One of the strategies to control the spread of MDR-TB is to decipher the aberrations at molecular level in order to formulate potent drugs that can treat the patients within short span of time. Determining the mutation profile of MDR in Pakistani populations will open new horizons for the improvement of drug treatment regimens to make it more effective or for the development of novel potent drugs and vaccines to better treat the drug-resistant TB. Moreover, this study will be help in disease control program.

Abstract Background The emergence of multidrug-resistant tuberculosis (MDR-TB) poses a serious obstacle to global TB control programs. Methods We carried out a prospective, randomized, multicenter study in China that was focused on the potential of a shorter regimen containing clofazimine (CFZ) for the treatment of MDR-TB. There were 135 MDR-TB cases that met eligibility requirements and were randomly stratified into either the control group or experimental group. Patients in the control group received an 18-month treatment regimen, whereas patients in the experimental group received a 12-month treatment regimen containing CFZ. Results At the completion of the treatment period, the difference in sputum-culture conversion rates between the experimental group and the control group was not significant. Notably, by the end of 3 months of treatment, 68.7% patients receiving the experimental regimen had sputum-culture conversion, as compared with 55.9% of those receiving the control regimen; this was a significant difference, suggesting an early sputum conversion (P = .04). There were 67 adverse events reported in 56 patients in this study, including 32 in the control group and 35 in the experimental group. No significant difference in the overall incidences of adverse events was observed between the 2 groups. Conclusions The MDR-TB patients treated with the shorter regimen containing CFZ had a comparable successful outcome rate when compared to those with the standard regimen. The patients assigned to the experimental group achieved more rapid sputum-culture conversion, reflecting superior antimicrobial activity against MDR-TB.

The immune system is central to ensuring the consistency of the body's homeostasis. The state of the body's natural resistance is determined by a set of non-specific protective mechanisms. Lymphocytes and phagocytes are actively involved in maintaining immunity. Lymphocytes recognize the antigens of pathogenic microorganisms, and phagocytes absorb and destroy the pathogens themselves. During the weaning of piglets from sows there is a decrease in the protective forces of their body. During this period, the natural resistance of the piglets is reduced due to the stressful situation caused by changing conditions of confinement, the transition to full feed and lack of sows. The immune system of weaning pigs is relatively weak, so when exposed to environmental and technological stressors, they become susceptible to various diseases. The use of probiotic drugs stimulates the activity of the immune system, prevents stress and immunodeficiency. One of these probiotics is the probiotic of domestic production Protecto-active. It w observed the the influence of the probiotic Protecto-active on the indices of nonspecific resistance of the young pigs organism to the growth. An increase in bactericidal activity of blood serum by 12.10% (P <0.05) and lysozyme activity of blood in the piglets of the experimental group was increased by 3.71% compared to control, which indicates the activation of the body's defenses and the increase in adaptive capacity. An important step in the study of the influence of the probiotic Protekto-active on the state of the immune system is to determine the phagocytic activity of neutrophils, phagocytic index and phagocytic number. In the experimental group of piglets that were fed the probiotic Protecto-active, we found an increase in leukocyte phagocytic activity by 9.0% (P <0.001), a phagocytic index by 51.7% (P<0.001) and a phagocytic number by 24.8% ( P <0.01) compared with the control group. Thus, using a probiotic Protecto-active, all indicators of phagocytosis increase: the number of phagocytes increases, their ability to capture microorganisms and increases their digestive capacity, it increases the bacterial and lysozyme activity of blood serum, which is positively reflected in the immunobiosity. Key words: probiotic, phagocytosis, phagocytic index, phagocytic number, phagocytic activity of leukocytes, cellular immunity, piglets

SETTING: The World Health Organization (WHO) recommends that multidrug-resistant tuberculosis (MDR-TB) treatment should be managed in collaboration with multidisciplinary advisory committees (consilia). A formal national Consilium has been established in France since 2005 to provide a centralised advisory service for clinicians managing MDR-TB and extensively drug-resistant (XDR-TB) cases.OBJECTIVE: Review the activity of the French TB Consilium since its establishment.DESIGN: Retrospective description and analysis of the activity of the French TB Consilium.RESULTS: Between 2005 and 2016, 786 TB cases or contacts of TB cases were presented at the French TB Consilium, including respectively 42% and 79% of all the MDR-TB and XDR-TB cases notified in France during this period. Treatment regimens including bedaquiline and/or delamanid were recommended for 42% of the cases presented at the French TB Consilium since 2009. Patients were more likely to be presented at the French TB Consilium if they were born in the WHO Europe Region, had XDR-TB, were diagnosed in the Paris region, or had resistance to additional drugs than those defining XDR-TB.CONCLUSION: The French TB Consilium helped supervise appropriate management of MDR/XDR-TB cases and facilitated implementation of new drugs for MDR/XDR-TB treatment.

ABSTRACT An in-house-developed pncA sequencing assay for analysis of pyrazinamide (PZA) resistance was evaluated using 162 archived Mycobacterium tuberculosis complex (MTBC) isolates with phenotypic PZA susceptibility profiles that were well defined by analysis of Bactec MGIT 960 PZA kit and PZase activity data. Preliminary results showed 100% concordance between pncA sequencing and phenotypic PZA drug susceptibility test (DST) results among archived isolates. Also, 637 respiratory specimens were prospectively collected, and 158 were reported as MTBC positive by the Abbott Realtime MTB assay (96.3% sensitivity [95% confidence interval {CI}: 92.2% to 98.7%]; 100% specificity [95% CI: 99.2% to 100.0%]). Genotypic and phenotypic PZA resistance profiles of these 158 MTBC-positive specimens were analyzed by pncA sequencing and Bactec MGIT 960 PZA kit, respectively. For analysis of PZA resistance, pncA sequencing detected pncA mutations in 5/5 (100%) phenotypic PZA-resistant respiratory specimens within 4 working days. No pncA mutations were detected among PZA-susceptible specimens. Combining archived isolates with prospective specimens, 27 were identified as phenotypic PZA resistant with pncA mutation. Among these 27 samples, 6/27 (22.2%) phenotypic PZA-resistant strains carried novel pncA mutations without rpsA and panD mutations. These included 5 with mutations (a deletion [Del] at 383T [Del383T], Del 380 to 390, insertion of A [A Ins] at position 127, A Ins at position 407, and G Ins at position 508) in pncA structural genes and 1 with a mutation (T-12C) at the pncA promoter region. All six of these strains had no or reduced PZase activities, indicating that the novel mutations might confer PZA resistance. Additionally, 25/27 phenotypic PZA-resistant strains were confirmed multidrug-resistant tuberculosis (MDR-TB) strains. As PZA is commonly used in MDR-TB treatment regimens, direct pncA sequencing will rapidly detect PZA resistance and facilitate judicious use of PZA in treating PZA-susceptible MDR-TB.

This study was conducted to investigate the effects of balance training with electromyogram-triggered functional electrical stimulation (EMG-triggered FES) to improve static balance, dynamic balance, and ankle muscle activation in stroke patients. Forty-nine participants (>6 months after stroke) were randomly assigned to the experimental group (n = 25) and the control group (n = 24). The experimental group underwent balance training with EMG-triggered FES for 40 min a day, 5 days a week, for a 6-week period in addition to general rehabilitation. The control group underwent balance training without EMG-triggered FES along with conventional therapy. Outcome measures included static balance ability, dynamic balance ability, and leg muscle activation. The static and dynamic balance abilities were significantly improved after intervention in both groups (p < 0.05), although the experimental group showed considerably greater improvement than the control group (p < 0.05). Leg muscle activation on the affected side resulted in significant improvements in the experimental group (p < 0.05) when compared with baseline but not in the control group. Balance training with EMG-triggered FES is an acceptable and effective intervention to improve the static balance, dynamic balance, and ankle muscle activation in stroke patients.

Objective: To explore the effects of an eight-week core stability program on balance ability in persons with Parkinson’s disease. Design: Randomized controlled trial. Setting: A local Parkinson’s association. Subjects: A total of 44 participants with a clinical diagnosis of Parkinson’s disease were randomly assigned to an experimental ( n = 22) or control group ( n = 22). Intervention: The experimental group received 24 sessions of core training, while the control group received an intervention including active joint mobilization, muscle stretching, and motor coordination exercises. Main measures: The primary outcome measure was dynamic balance evaluated using the Mini-Balance Evaluation Systems Test. Secondary outcomes included the balance confidence assessed with the Activities-specific Balance Confidence Scale and standing balance assessed by the maximal excursion of center of pressure during the Modified Clinical Test of Sensory Interaction on Balance and the Limits of Stability test. Results: After treatment, a significant between-group improvement in dynamic balance was observed in the experimental group compared to the control group (change, 2.75 ± 1.80 vs 0.38 ± 2.15, P = 0.002). The experimental group also showed a significant improvement in confidence (change, 16.48 ± 16.21 vs 3.05 ± 13.53, P = 0.047) and maximal excursion of center of pressure in forward (change, 0.86 ± 1.89 cm vs 0.17 ± 0.26 cm, P = 0.048), left (change, 0.88 ± 2.63 cm vs 0.07 ± 0.48 cm, P = 0.010), and right (change, 1.63 ± 2.82 cm vs 0.05 ± 0.17 cm, P = 0.046) directions of limits of stability compared to the control group. Conclusion: A program based on core stability in comparison with non-specific exercise benefits dynamic balance and confidence and increases center of mass excursion in patients with Parkinson’s disease.

Background Due to the many problems associated with reduced balance and mobility, providing an effective and engaging rehabilitation regimen is essential to progress recovery from impairments and to help prevent further degradation of motor skills. Objectives The purpose of this study was to examine the feasibility and benefits of physical therapy based on a task-oriented approach delivered via an engaging, interactive video game paradigm. The intervention focused on performing targeted dynamic tasks, which included reactive balance controls and environmental interaction. Design This study was a randomized controlled trial. Setting The study was conducted in a geriatric day hospital. Participants Thirty community-dwelling and ambulatory older adults attending the day hospital for treatment of balance and mobility limitations participated in the study. Interventions Participants were randomly assigned to either a control group or an experimental group. The control group received the typical rehabilitation program consisting of strengthening and balance exercises provided at the day hospital. The experimental group received a program of dynamic balance exercises coupled with video game play, using a center-of-pressure position signal as the computer mouse. The tasks were performed while standing on a fixed floor surface, with progression to a compliant sponge pad. Each group received 16 sessions, scheduled 2 per week, with each session lasting 45 minutes. Measurements Data for the following measures were obtained before and after treatment: Berg Balance Scale, Timed “Up & Go” Test, Activities-specific Balance Confidence Scale, modified Clinical Test of Sensory Interaction and Balance, and spatiotemporal gait variables assessed in an instrumented carpet system test. Results Findings demonstrated significant improvements in posttreatment balance performance scores for both groups, and change scores were significantly greater in the experimental group compared with the control group. No significant treatment effect was observed in either group for the Timed “Up & Go” Test or spatiotemporal gait variables. Limitations The sample size was small, and there were group differences at baseline in some performance measures. Conclusion Dynamic balance exercises on fixed and compliant sponge surfaces were feasibly coupled to interactive game-based exercise. This coupling, in turn, resulted in a greater improvement in dynamic standing balance control compared with the typical exercise program. However, there was no transfer of effect to gait function.

Randomized clinical trials represent the gold standard in therapeutic research. Nevertheless, observational cohorts of patients treated for multidrug-resistant TB (MDR-TB) or rifampin-resistant TB (RR-TB) also play an important role in generating evidence to guide drug-resistant TB care. Generally, summary exposure classifications (e.g., ‘ever vs. never´, ‘exposed at baseline´) have been used to characterize drug exposure in the absence of detailed longitudinal data on MDR-TB regimen changes. These summary classifications, along with an absence of data on covariates that change throughout the course of treatment, constrain researchers´ ability to answer the most relevant questions while accounting for known biases. In this paper, we highlight the importance of regimen changes in improving inference from observational studies of longer MDR-TB treatment regimens, and offer an overview of the data and analytic strategies required to do so.

One of the real ways of increasing the production of livestock products is to increase the conservation of young animals, the mortality rate of which remains at this time still very high. Many calf treatment regimens have been developed, but they are not always effective, which prompts scientists and practitioners to improve already known methods of treatment, to find and justify new medical preparation. Material for research were dry-cows, healthy and sick calves. After the clinical examination of cows, the experiment was conducted in two phases: the first phase – in 3 groups of cows, the second – in clinical healthy and sick calves. Mineral supplement of Sapocorm were added to the first experimental group of cows; cows of the second experimental group – the preparation Betamint; animals of control group get basic diet. At the second phase, a group of healthy calves, as well as control and two experimental groups of patients were formed. The first group was treated with Intecol in combination with the probiotic Vetom. Calves of the second group – the preparation Intecoll, but in a complex with electrolyte solution Electrosol oral. The calves of the control group were treated with 4% solution of gentamicin sulfate and 30% solution of natrium thiosulfate. It was found out that during the dry period, cows were often subjected to metabolic disorders, and the causes of digestive disorders in calves were associated with a metabolic disorders in cows as a result of malnutrition. In the first stage of the research, the data obtained show the stimulatory effect of Betamint on the processes of hemopoiesis of the cows. In other side,  the probable magnification increase hemoglobin in the blood of cows can be explained by the influence of the components of the preparation on the metabolism of proteins. In cows of the first experimental group, which received the mineral supplement of Sapocorm, there were no probable changes in these indices. The next stage of the work was aimed at studying the effectiveness of preparation for the treatment of sick calves. In the analysis of biochemical parameters, was obtained low effectiveness of control group treatment, which was manifested by a slight increase in the biochemical parameters of the blood of diseased calves, which indicates an ineffective action of preparation. In the treatment of calves in the first group, the general condition was normal within 4–5 days of treatment. This indicates the complex effect of compounds and other elements that are components of the preparation Intecol and probiotic Vetom, on restoring the structure and functions of digestion. An analysis of the biochemical parameters of the blood of the second group when treated with the preparation Intecol and Electrosol oral plagued the normalization of the general state occurred within 2–3 days of treatment. The revealed changes indicate the complex influence of nutrients, which are components of the preparation Electrosol oral. On the basis of the conducted studies, the positive influence of the proposed treatment regimens and the effectiveness of the use of a complex of preparation with the antibiotic “Intecol” has been proved.
