There was no difference in estradiol level between healthy women with GG+AG genotype and AA genotype.

  The aim Was to evaluate the anatomical variability of the frontal and maxillary sinuses, ostiomeatal complex components (OMC) and to identify factors that contribute to complications of inflammatory processes and development of odontogenic maxillary sinusitis.
 
  Materials and methods The study involved assessment of 100 spiral computed tomograms (SCT) of human patients without pathological processes in the PNS area. The basic parameters of the anatomical structure of the ostiomeatal complex (the area of the hooked process and the middle nasal conch, their transverse dimensions, the density and dimensions of the natural connection), the thickness and the density of the lower wall of the maxillary and frontal sinuses were determined. These parameters were investigated by the method of uncertainty calculation.
 
  Results The findings showed that the bone density of the maxillary sinus on the left was 57.713 ± 440.356 Hu (minimum), 1101.507 ± 613.4882 Hu (maximum); 96.2752 ± 395.0 and 1028.691 ± 620.4051 on the e surrounding tissues and the development of complications.
  Introduction A novel coronavirus SARS-CoV-2 RNA, detected by reverse-transcription polymerase chain reaction (RT-PCR) was identified as the cause of a cluster of pneumonia cases in Wuhan, China. It rapidly spread, at first in China, then resulting in an epidemic in other countries throughout the world. One of such controversial topics is the issue of diagnostics and interpretation of test for COVID-19. According to Polish and global guidelines, the basis for diagnosis is molecular testing - real-time reverse transcriptasepolymerase chain reaction (RT-PCR). Taking all these data into consideration, the aim of the study was to compare RT-PCR with serological test in our employees post-exposure.

  Material and methods 79 employees of the Clinic, 19 men and 60 women in the age rp of employees.
 Conclusions As routine tests for patients have been implemented widely, but similar solutions for employees have not gained popularity. Use of personal protective equipment (PPE) e.g. facemask and shields, transparent screens, disposable medical uniforms, minimalization the contact time, increasing distance from both colleagues and patients (if possible), and strictly follow sanitary procedures largely contributed to the absence of illness in the surveyed group of employees.
  The aim To determine of the factors influencing the formation of "kissing" duodenal bulb ulcer in patients with chronic non-atrophic gastritis.
 
  Materials and methods The data of a comprehensive examination of 34 patients with chronic non-atrophic gastritis were analyzed, in which the examination revealed "kissing" ulcers of the duodenal bulb (primary group), and 37 patients with chronic non-atrophic gastritis, in which single ulcers were detected in the bulb (control group). Comprehensive examination included step-by-step intragastric pH-metry, esophagogastroduodenoscopy, helicobacter infection test (НР) (helicobacter urease test and microscopic examination of stained smears), histological investigations of the gastric stump mucous, material for which was taken during endoscopy from 4 topographical zones from the middle third of the gastric antrum and body of stomach on the big and small curvature.
 
  Results In the course of the examination, the presence of chronic non-atrophic gastritis in 100% of cases non-atrophic gastritis only if the patients have a peculiar anatomical structure of the bulb, in which the lumen has an oval shape.
  The aim To obtain the first estimates of the current prevalence of nasal carriage of methicillin-resistant Staphylococcus aureus (MRSA) among healthcare workers (HCWs) in the departments of Otorinolaryngology and Dentistry and to determine of genes virulence factors (Panton Valentine Leukocidine (PVL) genes).
 
  Materials and methods We performed a multicenter cross-sectional study. The susceptibility to antibiotics was determined by disk diffusion method according to the European Committee on Antimicrobial Susceptibility Testing. The virulence factor encoding genes, mecA, lukS-lukF, were detected by Polymerase Chain Reaction (PCR).
 
  Results Incidence rate of S. aureus nasal carriage among HCWs was 36.2%, whereas MRSA carriage was 17%. Prevalence of MRSA carriage rate was 34.9% in Otorhinolaryngology departments and 9.7% in Dentistry. PCR testing confirmed that all MRSA strains were mecA gene-positive. The virulence factor encoding genes were detected in 82.3% of the S.  https://www.selleckchem.com/products/fhd-609.html  aureus isolates from HCWs. Among S.auol measures and early therapeutic decisions.
  Since the outbreak of COVID-19, the development of dashboards as dynamic, visual tools for communicating COVID-19 data has surged worldwide. Dashboards can inform decision-making and support behavior change. To do so, they must be actionable. The features that constitute an actionable dashboard in the context of the COVID-19 pandemic have not been rigorously assessed.
 
  The aim of this study is to explore the characteristics of public web-based COVID-19 dashboards by assessing their purpose and users ("why"), content and data ("what"), and analyses and displays ("how" they communicate COVID-19 data), and ultimately to appraise the common features of highly actionable dashboards.
 
  We conducted a descriptive assessment and scoring using nominal group technique with an international panel of experts (n=17) on a global sample of COVID-19 dashboards in July 2020. The sequence of steps included multimethod sampling of dashboards; development and piloting of an assessment tool; data extraction and an initial round of actionability scoring; a workshop based on a preliminary analysis of the results; and reconsideration of actionability scores followed by joint determination of common features of highly actionable dashboards.
