OBJECTIVE. The purpose of our comprehensive analysis is to assess the prospects for the effects of the interaction between coronavirus disease 2019 (COVID‑19) and tuberculosis (TB) and to strategize the risks of spreading TB infection in a coronavirus pandemic. MATERIALS AND METHODS. Test access to full-text and abstract databases was used. RESULTS AND DISCUSSION. An analysis of the available literature has shown that a 3-month lockdown and a long 10-month recovery worldwide could lead to an additional 6.3 million TB cases and another 1.4 million TB deaths between 2020 and 2025. On average, the detection of TB in Ukraine decreased by 27.4 %, and the incidence of TB among children decreased by 34.5 %. This is an alarming figure because we know very well that within 6 months the number of patients with TB has not decreased, they simply stopped being detected. In addition, COVID‑19 may accelerate the activation of latent TB infection and thus increase the number of active cases. CONCLUSIONS. The overall incidence of TB in 2021 will increase to the level that was last observed between 2013 and 2016. The epidemiological indicators of TB control are expected to deteriorate for at least 5-8 years due to the COVID‑19 pandemic. Long-term results can be strongly affected by the rate of short-term recovery. Priority should be given to all governments, during a pandemic, to ensure the continuity of basic health care, including the implementation of national TB programs.

Medical, social and economic relevance of inflammatory diseases of the woman's reproductive organs requires a very careful attitude to the diagnosis and treatment of this pathology. The number of patients with genital infections and inflammatory diseases of the pelvic organs can takes the first place in structure of gynecological morbidity, and is 60.4-65.0%, and this fact is not unique to Russia, but all over the world. Incidence rate of inflammatory diseases of the pelvic organs in the first decade of the twenty-first century is increased at 1.4 times in patients who are from 18 to 24 years old and at 1.8 times in patients aged 25-29 years. At the same time, the cost of diagnosis and treatment has increased, reaching 50-60% of the total cost of providing gynecological care for population. The inflammatory diseases of pelvic organs are a collective concept. It includes of various nosological forms. There are numerous contradictions in the views on diagnostic approaches and treatment tactics, the nature of screening and control over the long-term results of treatment, the etiological and pathogenetic significance of various microorganisms found in the genital tract in patients with inflammatory diseases of the pelvic organs. Currently, there are many opinions among specialists about diagnostic approaches and treatment tactics, the type of screening and monitoring the long-term results of treatment, the etiological and pathogenetic role of various microorganisms which can be found in the genital tract in patients with inflammatory diseases. This review presents the results of a modern approach to the diagnosis, management and rehabilitation of patients with inflammatory diseases of the pelvic organs.

Latent Tb Infection

Abstract Background Health care workers (HCWs) are at risk for occupationally acquired Mycobacterium tuberculosis infection and tuberculosis (TB) disease due to repeated exposure to workplace tubercle bacilli. To determine whether continual mycobacterial stimulation correlates with increased expression of inhibitory T cell receptors, here we compared PD-1 receptor expression on surfaces of circulating T cells between naïve (uninfected) HCWs and HCWs with latent TB infection (LTBI). Result Data collected from 133 medical workers who met study selection criteria were included in the final analysis. QuantiFERON-TB Gold In-​Tube (QFT-GIT) testing yielded positive results for 32 HCWs, for an overall LTBI rate of 24.1%. Multivariate analysis identified HCW length of service > 15 years as an independent risk factor for a positive QFT-GIT result. In addition, comparisons of blood T cell subgroup profiles between QFT- and QFT+ groups indicated QFT+ subjects possessed greater proportions of mature (TM), transitional memory (TTM) and effector memory (TEM) CD4+ T cell subgroups and lower proportions of naïve T cells (TN). Moreover, the QFT+ group percentage of CD8+ T cells with detectable surface PD-1 was significantly higher than the corresponding percentage for the QFT- group. Meanwhile, no statistical intergroup difference was observed in percentages of CD4+ T cells with detectible surface PD-1. Conclusions Our data demonstrated that upregulated PD-1 expression on circulating CD8+, but not CD4+ T cells, was associated with latent TB infection of HCWs. As compared to other hospitals, occupational TB infection risk in our hospital was substantially mitigated by implementation of multitiered infection control measures.

Wrist Fusion

Fifteen patients with radioscapholunate (RSL) fusion for traumatic lesions of the radiocarpal junction, whose short-term results have been previously reported, were reassessed after an average follow-up time of 8 years. Five patients had undergone wrist fusion because of non-union or early progressive arthritis. Of the ten wrists with retained mobility, eight continued to function satisfactorily. Two wrists were painful for reasons other than secondary midcarpal arthritis. Patient satisfaction was comparable in both groups with the wrist score better for wrists with residual motion. The survival of RSL partial wrist fusion corresponded inversely with the number of preceding operations and the range of motion before partial fusion. Secondary midcarpal arthritis, if present, arose early and was well tolerated. Failures were strongly linked to technical mistakes and complications.

The issue of strengthening the damaged linear reinforced concrete elements have been engaged since 2008. We focused on the analysis of resistance and the characteristics of limit states of serviceability in the damaged and subsequently strengthened elements at a short-term loading. In the introduction phase, the strengthening of the elements was carried out with the following procedures – installation of an overlayer on the coupling board or a combination of the board and use of glass – fiber fabric (GFRP). The strengthening was also affected by the type of contact (reinforced/non-reinforced) – the deformed element/coupling board and its effect on resistance, type of deformation and serviceability. In the non-reinforced contact, we applied some of the types of adjustments to the surface of the strengthened element. At the moment, we are dealing with the effects of time and repeated load on the strengthened elements. The results correspond to the reinforced contact. The values are compared with the short-term results of the strengthened beams and with the long-term results of the beams prepared for strengthening.

Concussion Education

There has been a remarkable increase in the past 10 years in the awareness of concussion in the sports and recreation communities. Just as sport participants, their families, coaches, trainers, and sports organizations now know more about concussions, health care professionals are also better prepared to diagnose and manage concussions. As has been stated in the formal articles in this special issue on sport-related concussion, education about concussion is one of the most important aspects of concussion prevention, with the others being data collection, program evaluation, improved engineering, and introduction and enforcement of rules. Unfortunately, the incidence of concussion appears to be rising in many sports and thus, additional sports-specific strategies are required to reduce the incidence, short-term effects, and long term consequences of concussion. Enhanced educational strategies are required to ensure that individual participants, sports organizations, and health care professionals recognize concussions and manage them proficiently according to internationally recognized guidelines. Therefore, this paper serves as a “brief report” on a few important aspects of concussion education and prevention.

Long-term immunoreactivity to mycobacterial antigens in Bovis Calmette-Guérin (BCG)-vaccinated population is not well investigated. Herein, 361 volunteer healthy donors (HDs) with neonatal BCG vaccination from Shanghai region (China) were enrolled. They were subdivided into ESAT-6/CFP10- (E6C10-) and ESAT-6/CFP10+ (E6C10+) groups based on gamma-interferon release assays (IGRAs). Three mycobacterial antigens, including Rv0934, Rv3006, and Rv3841, were subjected to the determination of immunoreactivity by ELISPOT assay. The immunoreactivities to three mycobacterial antigens were firstly compared among TB patients (N=39), E6C10+ HDs (N=78, 21.61% of HDs) and E6C10- HDs (N=283, 78.39% of HDs). It was revealed that Rv3006 was dominant upon M.tb infection, while Rv3841 was likely to be more responsive upon latent TB infection. In E6C10- population, the immunoreactivity to Rv3841 maintained along with aging, whereas those to Rv3006 and Rv0934 attenuated in E6C10- HDs older than 45 years old. Our study implies the shift of dominant antigens at different infection statuses, providing the clues for the selection of mycobacterial antigens in vaccine development and precision revaccination in the future.
