Remdesivir therapy has been declared as efficient in the early stages of Covid-19. Of the 339 patients (males 55.8%, age 71(59;77) years) with a detectable viral load, 140 were treated with remdesivir (of those 103 in the ICU and 57 immunosuppressed) and retrospectively compared with 199 patients (of those 82 in the ICU and 28 immunosuppressed) who were denied therapy due to advanced Covid-19. The viral load was estimated by detecting nucleocapsid antigen in serum (n = 155, median 217(28;1524)pg/ml), antigen in sputum (n = 18, COI 18(4.6;32)), nasopharyngeal antigen (n = 44, COI 17(8;35)) and the real-time PCR (n = 122, Ct 21(18;27)). After adjustment for confounders, patients on remdesivir had better 12-month survival (HR 0.66 (0.44;0.98), p = 0.039), particularly when admitted to the ICU (HR 0.49 (0.29;0.81), p = 0.006). For the immunocompromised patients, the difference did not reach statistical significance (HR 0.55 (0.18;1.69), p = 0.3). The other most significant confounders were age, ICU admission, mechanical ventilation, leukocyte/lymphocyte ratio, admission creatinine and immunosuppression. The impact of monoclonal antibodies or previous vaccinations was not significant. Despite frequent immune suppression including haemato-oncology diseases, lymphopenia, and higher inflammatory markers in the remdesivir group, the results support remdesivir administration with respect to widely available estimates of viral load in patients with high illness severity.

OBJECTIVES: Given the lack of data on the seriousness of respiratory syncytial virus (RSV) infections in the Czech Republic, an analysis was made of available data on hospitalizations and the hospitalization risk was estimated by age group. METHODS: Data from the National Registry of Reimbursed Health Services and the National Registry of Hospitalizations were used for the analyses. Hospitalizations and deaths due to RSV infection (diagnoses J12.1, J20.5, J21.0) from 2017-2022 were analyzed by age group. RESULTS: Over the six-year period, there were 6,138 hospitalizations with the above diagnoses, ranging between years from 307 to 2,162. The estimated overall hospitalization risk per 100,000 population and year for diagnoses J12.1, J20.5, and J21.0 was 9.64, varying between 2.87 (2020) and 20.56 (2021). Age-group analysis showed the highest risk for children under 6 months of age (891.6/100,000 population and year) and the lowest for 20-34-year-olds (0.1/100,000 population and year). Children under 1 year of age accounted for 63.1% of hospitalizations with the above diagnoses. For patients 65 years and older, the annual hospitalization rates varied between 3.3-15.3%. The most frequent cause of RSV-associated hospitalizations was bronchitis, diagnosed in 55.4% of patients. Among those hospitalized with diagnoses J12.1, J20.5, and J21.0, 38 deaths were reported, representing a case fatality rate of 0.62%. The highest case fatality rate (6.5%) was observed in the age group 35-49 years. CONCLUSIONS: RSV-associated hospitalizations have been reported in all age groups in the Czech Republic. The highest RSV-associated hospitalization risk in 2017-2022 was estimated among children under 6 months of age. Passive surveillance using the available registries could currently provide the basis for measures specifically tailored to the youngest age categories. Data on the hospitalization of adults, particularly senior citizens, must be improved and complemented with active surveillance.

SARS-CoV-2 infection, which causes the respiratory disease COVID-19, has spread rapidly from Wuhan, China, since 2019, causing nearly 7 million deaths worldwide in three years. In addition to clinical risk factors such as diabetes, hypertension, and obesity, genetic variability is an important predictor of disease severity and susceptibility. We analyzed common polymorphisms within the LZTFL1 (rs11385942) and ABCA3 (rs13332514) genes in 519 SARS-CoV-2-positive subjects (164 asymptomatic, 246 symptomatic, and 109 hospitalized COVID-19 survivors) and a population-based control group (N?=?2,592; COVID-19 status unknown). Rare ABCA3 AA homozygotes (but not A allele carriers) may be at a significantly increased risk of SARS-CoV-2 infection [P?=?0.003; OR (95 % CI); 3.66 (1.47-9.15)]. We also observed a borderline significant difference in the genotype distribution of the LZTFL1 rs11385942 polymorphism (P?=?0.04) between the population sample and SARS-CoV-2-positive subjects. In agreement with previous studies, a nonsignificantly higher frequency of minor allele carriers was detected among hospitalized COVID-19 subjects. We conclude that a common polymorphism in the ABCA3 gene may be a significant predictor of susceptibility to SARS-CoV-2 infection.

BACKGROUND: Coronavirus disease (COVID-19), which is caused by the SARS-CoV-2 virus, has become a global pandemic. While susceptibility to COVID-19 is subject to several external factors, including hypertension, BMI, and the presence of diabetes, it is also genetically determined to a significant extent. Infectious agents require iron (Fe) for proper functioning. Carriers of mutations resulting in increased iron concentrations are understood to be at increased risk of COVID-19. METHODS: We examined HFE genotypes associated with hereditary haemochromatosis (rs1800562 and rs1799945 SNPs) in 617 COVID-19 patients (166 asymptomatic, 246 symptomatic and 205 hospitalised survivors) and 2 559 population-based controls. RESULTS: We found a higher frequency of the minor allele (Tyr282) of the rs1800562 polymorphism (P < 0.002) in patients compared to controls (8.5 % vs 5.5 %). Non-carriers of the minor allele were protected against SARS-Cov-2 infection (OR, 95 %CI; 0.59, 0.42-0.82). The frequency of minor allele carriers was almost identical across asymptomatic, symptomatic, and hospitalised survivors. The rs1799945 variant did not affect disease severity and its occurrence was almost identical in patients and controls (P between 0.58 and 0.84). CONCLUSIONS: In conclusion, our results indicate that presence of the rs1800562 minor allele, which is associated with hereditary haemochromatosis (thus increased levels of plasma Fe), increases susceptibility to SARS-CoV-2.

OBJECTIVES: To compare the performance of transvaginal and transabdominal ultrasound with that of the first-line staging method (contrast-enhanced computed tomography (CT)) and a novel technique, whole-body magnetic resonance imaging with diffusion-weighted sequence (WB-DWI/MRI), in the assessment of peritoneal involvement (carcinomatosis), lymph-node staging and prediction of non-resectability in patients with suspected ovarian cancer. METHODS: Between March 2016 and October 2017, all consecutive patients with suspicion of ovarian cancer and surgery planned at a gynecological oncology center underwent preoperative staging and prediction of non-resectability with ultrasound, CT and WB-DWI/MRI. The evaluation followed a single, predefined protocol, assessing peritoneal spread at 19 sites and lymph-node metastasis at eight sites. The prediction of non-resectability was based on abdominal markers. Findings were compared to the reference standard (surgical findings and outcome and histopathological evaluation). RESULTS: Sixty-seven patients with confirmed ovarian cancer were analyzed. Among them, 51 (76%) had advanced-stage and 16 (24%) had early-stage ovarian cancer. Diagnostic laparoscopy only was performed in 16% (11/67) of the cases and laparotomy in 84% (56/67), with no residual disease at the end of surgery in 68% (38/56), residual disease ≤ 1 cm in 16% (9/56) and residual disease > 1 cm in 16% (9/56). Ultrasound and WB-DWI/MRI performed better than did CT in the assessment of overall peritoneal carcinomatosis (area under the receiver-operating-characteristics curve (AUC), 0.87, 0.86 and 0.77, respectively). Ultrasound was not inferior to CT (P = 0.002). For assessment of retroperitoneal lymph-node staging (AUC, 0.72-0.76) and prediction of non-resectability in the abdomen (AUC, 0.74-0.80), all three methods performed similarly. In general, ultrasound had higher or identical specificity to WB-DWI/MRI and CT at each of the 19 peritoneal sites evaluated, but lower or equal sensitivity in the abdomen. Compared with WB-DWI/MRI and CT, transvaginal ultrasound had higher accuracy (94% vs 91% and 85%, respectively) and sensitivity (94% vs 91% and 89%, respectively) in the detection of carcinomatosis in the pelvis. Better accuracy and sensitivity of ultrasound (93% and 100%) than WB-DWI/MRI (83% and 75%) and CT (84% and 88%) in the evaluation of deep rectosigmoid wall infiltration, in particular, supports the potential role of ultrasound in planning rectosigmoid resection. In contrast, for the bowel serosal and mesenterial assessment, abdominal ultrasound had the lowest accuracy (70%, 78% and 79%, respectively) and sensitivity (42%, 65% and 65%, respectively). CONCLUSIONS: This is the first prospective study to document that, in experienced hands, ultrasound may be an alternative to WB-DWI/MRI and CT in ovarian cancer staging, including peritoneal and lymph-node evaluation and prediction of non-resectability based on abdominal markers of non-resectability. © 2021 International Society of Ultrasound in Obstetrics and Gynecology.

Infection by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the virus that causes coronavirus disease (COVID-19), has spread widely around the globe. Significant inter-individual differences have been observed during the course of the infection, which suggests that genetic susceptibility may be a contributing factor. CC chemokine receptor 5 (CCR5), which acts as a co-receptor for the entry of HIV-1 into cells, is promising candidate whose can have an influence on SARS-CoV-2 infection. A genetic mutation known as CCR5Delta32, consisting of a 32-nucleotide deletion, encodes a truncated protein that protects homozygous carriers of the deletion from HIV-1 infection. Similarly, inhibition of CCR5 seems to be protective against COVID-19. In our study, we successfully genotyped 416 first-wave SARS-CoV-2-positive infection survivors (164 asymptomatic and 252 symptomatic) for CCR5?32, comparing them with a population based sample of 2,404 subjects. We found the highest number (P=0.03) of CCR5Delta32 carriers in SARS-CoV-2-positive/COVID-19-asympto-matic subjects (23.8 %) and the lowest number in SARS-CoV-2-positive/COVID-19-symptomatic patients (16.7 %), with frequency in the control population in the middle (21.0 %). We conclude that the CCR5?32 I/D polymorphism may have the potential to predict the severity of SARS-CoV-2 infection.

BACKGROUND: Bladder neoplasms represent a significant disease burden in the Czech population. This study aimed to perform a complex time trend analysis of incidence, mortality, and survival of 76,505 patients with bladder neoplasms based on the Czech National Cancer Registry for 1977-2017. MATERIALS AND METHODS: The time trends of incidence and mortality were evaluated using the joinpoint regression. The relative survival and Cox proportional hazards model were used for survival analysis. RESULTS: After 2004, a significant annual decrease by 1.9% in the incidence of malignant tumors of the bladder (C67) was observed, accompanied by a sharp annual increase in the incidence of in situ bladder cancer (D090) by 16.9%. For mortality from malignant tumors of the bladder, a significant decrease by 1.4% annually was detected after 1998. The decline in both incidence and mortality was most pronounced in the below-65 years age group and in patients with a localized stage at dia-gnosis. While a significant decline in both incidence and mortality was observed for the first primary malignant tumors of the bladder, both these measures increased for malignant tumors of the bladder as subsequent primary neoplasms. The five-year relative survival of patients with malignant tumors of the bladder increased from 52.1% in 1990-1993 to 62.3% in 2013-2017. However, comparing the periods 2003-2007 and 2013-2017, a decrease has been observed. CONCLUSION: The decrease in the incidence and survival of malignant tumors of the bladder in the recent period is in particular caused by improved detection of in situ bladder cancer and classification changes. Other reasons for the decreasing survival include the increasing age at dia-gnosis, the growing number of subsequent primary neoplasms, and the increasing proportion of smokers among patients.

Triple-positive breast cancer (TPBC), i.e. HER2-positive (HER2+) and hormone receptors-positive breast cancer, is a specific subgroup of breast cancers. TPBC biology is characterized by strong mutual interactions between signaling pathways stimulated by estrogens and HER2 amplification. The present study aims to carry out a population-based analysis of treatment outcomes in a cohort of hormone receptor (HR) positive and negative breast cancer patients who were treated with anti-HER2 therapy in the Czech Republic. The BREAST research database was used as the data source for this retrospective analysis. The database covers approximately 95% of breast cancer patients treated with targeted therapies in the Czech Republic. The analysis included 6,122 HER2-positive patients. The patients were divided into two groups, based on estrogen receptor (ER) or progesterone receptor (PR) positivity: hormone receptor negative (HR-) patients had both ER- and PR-negative tumors (n=2,518), unlike positive (HR+) patients (n=3,604). HR+ patients were more often diagnosed premenopausal at the time of diagnosis, presented more often at stage I or II and their tumors were less commonly poorly differentiated. The overall survival (OS) was significantly higher in subgroups of HR+ patients according to treatment setting. When evaluated by stages, significantly higher OS was observed in HR+ patients diagnosed at stages II, III, and IV and regardless of tumor grade.

The article describes the development of oncosurgery in the Czech Republic since the beginning of the century, as well as other perspectives regarding this specialty. The development of surgical treatment of solid malignant tumours in the Czech Republic was evaluated according to the National Cancer Register database and compared to the neighbouring countries, and the educational system of surgeons in oncosurgery was assessed. Although surgery plays a key role in cancer therapy, starting from the beginning of this millennium it has been pushed aside as a service specialty for other disciplines in oncology. In 2002, these changes were supported by the activities of the newly founded Division of Oncosurgery under the Czech Society for Oncology, which became part of the Czech Surgical Society in 2016. An official educational programme of surgeons in oncology was successfully implemented and since 2011, a specialization examination in oncosurgery has been introduced, organized by the subdepartment of oncosurgery of the Institute of Postgraduate Medical Education (IPVZ), Prague. To date, this examination has been completed by 112 physicians and approximately the same number is currently registered in the educational programme. Currently, 34 centres are accredited for education in oncosurgery. The establishment of Complex Oncology Centres based on an initiative of the Czech Society for Oncology of 2006 only addressed pharmaceutical and radiation oncology. Despite progress in oncosurgery, more clearly defined conditions for this specialty are needed. Conclusion: The education of surgeons in oncosurgery should be continued. It is necessary to expand the number of centres with accreditation for oncosurgery and develop a concept for oncosurgery in the Czech Republic which would be associated with rational concentration of this treatment in connection with organization and provision of continuous urgent and acute surgical care in the Czech Republic, including control mechanisms to ensure its quality. This proposal should be discussed by the Czech Surgical Society in order to further enhance the quality of oncosurgery in the Czech Republic.

BACKGROUND: Plasma cell leukemia (PCL) is a rare but most aggressive form of monoclonal gammopathies. PCL is characterized by the presence of clonal plasma cells in peripheral blood. There are two forms of PCL - primary which presents de novo in patients with no evidence of previous multiple myeloma and secondary which is a leukemic transformation of relapsed or refractory dis-ease in patients with previously recognized multiple myeloma. MATERIALS AND METHODS: This is the first study to provide information on PCL epidemiology in the Czech population us-ing The Czech National Cancer Registry (CNCR) as the basic source of data for the population-based evaluation of PCL epidemiology. RESULTS: Accord-ing to CNCR data, there were on average six newly dia-gnosed cases of PCL and four deaths caused by PCL each year in the Czech Republic in the period 2000- 2015. PCL incidence in the Czech Republic was reported at 0.57 per million in 2000- 2015. We suppose that most reported cases of PCL are primary PCL because secondary PCL is a relapse of a previously reported myeloma and, in most cases, is not coded as an independent dia-gnosis in the CNCR. CONCLUSION: Data from registries such as the CNCR can provide useful information on epidemiology of various dis-eases. These data, however, have several limitations, such as dia-gnostic criteria and proper cod-ing of not only the dis-ease itself, but also its various forms. These limitations have to be taken into account dur-ing the process of results interpretation.
