The problem of HIV infection in Russia remains topical, despite the active prevention and use of antiretroviral therapy. The main causes of hospitalization and lethal outcome among HIV patients are respiratory diseases, community-acquired pneumonia in particular. This article analyzes the literature data on causative agents of pneumonia in HIV-positive patients, the possibility to vaccinate such patients and its effectiveness.

Objective. To assess the epidemiological manifestations of the incidence of respiratory system diseases (RSD) among the military personnel of the military units of the Central Military Region. Materials and methods. The morbidity analysis was carried out according to official statistics for 20032019 with an assessment of long-term dynamics, structure and spatial characteristics. Results. Despite the preventive measures taken, the incidence of respiratory diseases in the troops remains high and continues to grow. The conscript servicemen are at risk. In the structure of RSD incidence, acute respiratory viral infections (ARVI) take the leading place, tonsillitis and bronchitis are in the second place, and community-acquired pneumonia (CAP) is in the third place. Differences in the trends of long-term dynamics of morbidity in various clinical forms of RSD were revealed. The Siberian Federal Region is the most favorable regarding RSD incidence. Conclusions. The incidence of respiratory diseases among conscripts is higher than that in contract servicemen, with downward trend for CAP and growth for ARVI and bronchitis.

Pakistan is also seeing the profound effect of the outbreak of COVID-19, which demands an urgent investigation of literature and further scientific investigation for cure and prevention. This study has employed the systematic approach for searching the literature from the recently compiled database of researches namely COVID-19 Open Research Dataset (CORD-19) and related diseases. The literature on Pakistan has shown the evidence of human-to-human and animal-to-human transmission of viruses, the presence of antibodies of MERS-CoV in camels, and careless attitude towards preventive measures of such respiratory diseases. There is a lot of gap in the literature regarding coronaviruses and their antibodies creating herd immunity for another coronavirus and COVID-19. In particular to Pakistan, and in general, for other developing countries, a weak health-care system coupled with the trembling economy has many implications of COVID-19 which should be carefully thought-out to combat the spread.

In the literature review the authors present an analysis of the current stateproblem of ovarian cancer and ways of its possible solution. According to clinicalobservations and conducted in recent decades by morphological,immunohistochemical and molecular genetic studies it is fairly proved that theprimary cause of serous ovarian cancer is the pathology of the mucous layer offallopian tube. In the fallopian tube as a result of ciculation of inflammation andcarcinogens elements arises dysplasia of the mucosa with the development of thepreinvasive and initial invasive carcinoma with subsequent damage of the ovariesand pelvic peritoneum. Retrospective studies of a significant number of women’shealth status who had a deligation or removal of fallopian tubes in previous years showed a decrease in the disease incidence of serous ovarian cancer from 30 to 90%. The conclusions about the possibility of preventive measures of ovariancancer by opportunistic salpingectomy at post-productive age are made. In many world countries (Canada, China, France, Italy, Austria) the introduction of such a method of prevention has been started. We believe that in Ukraine there is an urgent need and all possibilities to solve this problem. Key words: ovarian cancer, preventive measures, opportunistic salpingectomy.

Etiologic Agents

Pneumonia is a common illness accounting for majority of hospitalizations worldwide with significant mortality and morbidity. Antimicrobial therapy, being the main stay of treatment, the choices of antibiotics depends on the nature of the etiologic agents and the host factors. The current study was aimed to identify the bacterial & fungal etiologic agents of Community Acquired Pneumonia (CAP) in Immunocompromised (IC) patients, with their antimicrobial resistant pattern and to analyze the associated immunocompromised states. Various respiratory samples from study group of 75 immunocompromised patients with features of pneumonia were collected, processed and the isolates were identified with their antimicrobial susceptibility& resistance pattern according to CLSI guidelines. The results were analyzed statistically. Diabetes mellitus is the most common immunocompromised state (48%) associated with CAP. Monomicrobial and polymicrobial infection rates were 80.36% and 19.64% respectively. Gram negative pathogens and fungal pathogens were identified in 60% and 25.37% of culture positive cases respectively. Diabetes mellitus is commonly found in association with polymicrobial infection (19.44%) and fungal infection (16.66%). Drug resistant strains comprise about 75% of MRSA strains, 72.72 % of ESBL producers and 3.44% of Amp C producers. As the number of elderly people with associated IC state is on rise, with change in the pattern of microbial etiologic agents causing CAP, a prior knowledge of the host and microbial factors will help in formulating empirical antimicrobial therapy and proper treatment thereby curbing the spread of infections by drug resistant pathogens and the associated morbidity and mortality.

Abstract Background SARS-CoV-2 binding receptor ACE2 and the spike protein priming protease TMPRSS2 are co-expressed in human placentae. It is unknown whether their expression is altered in the context of HIV infection and antiretroviral therapy (ART). Methods We compared mRNA levels of SARS-CoV-2 cell-entry mediators ACE2, TMPRSS2 and L-SIGN (an alternative entry receptor) by qPCR in 105 placentae: 45 from pregnant women with HIV (WHIV) exposed to protease inhibitor (PI)-based ART, 17 from WHIV on non-PI-based ART, and 43 from HIV-uninfected women. Results ACE2 levels were lower, while L-SIGN levels were higher in placentae from WHIV on PI-based ART as compared to those on non-PI-based ART and to HIV-uninfected women. TMPRSS2 levels were similar between groups. Black race was significantly associated with lower expression of ACE2 and higher expression of L-SIGN. ACE2 levels were significantly higher in placentae of female fetuses. Discussion We have identified pregnant women of Black race and WHIV who are on PI-based ART to have relatively lower expression of placental ACE2 than those of White race and HIV-uninfected women. This effect may potentially contribute to altered susceptibility to COVID-19 in these women, either favorably; by reduced viral entry, or detrimentally; by loss of ACE2 protection against hyperinflammation.

Poult Enteritis

Poult enteritis and mortality syndrome (PEMS) is one of the most significant problem affecting turkeys and continues to cause severe economic losses worldwide. Although the specific causes of PEMS remains unknown, this syndrome might involve an interaction between several causative agents such as enteropathogenic viruses (coronaviruses, rotavirus, astroviruses and adenoviruses) and bacteria and protozoa. Non-infectious causes such as feed and management are also interconnected factors. However, it is difficult to determine the specific cause of enteric disorders under field conditions. Additionally, similarities of clinical signs and lesions hamper the accurate diagnosis. The purpose of the present review is to discuss in detail the main viral possible causative agents of PEMS and challenges in diagnosis and control.
