RESUMO
Amid the COVID-19 pandemic, mask-wearing has become a common practice in the foodservice industry to prevent the spread of respiratory diseases. Like kitchen utensils, a mask may serve as a vehicle for cross-contamination of pathogens during food handling. The objective of this study was to quantify cross-contamination between tasks of handling contaminated chicken and chopping lettuce. Chicken breasts were inoculated with a high or a low level of nonpathogenic Escherichia coli surrogates (ca. 6 or 4 log CFU/ml) and sliced for 1, 5, or 10 min. During slicing, duplicate, single-use medical masks were touched each minute. One mask was immediately sampled, but the second mask was used to contaminate lettuce by touching the mask each minute while chopping the lettuce for 5 min. E. coli were enumerated from the second mask and lettuce. Masks touched while slicing both high- and low-inoculated chicken showed significant contamination (0.8-4.9 log CFU/cm2) after each slicing scenario of 1, 5, or 10 min (P > 0.05). Lettuce was significantly contaminated regardless of inoculation level (1.0-3.2 log CFU/g). Slicing time was a significant factor in some cases (P < 0.05), whereas inoculation level was not (P > 0.05). Data indicate masks can be a source of cross-contamination if not replaced appropriately.
RESUMO
Introduction. According to International Agency for Research on Cancer in 2040, about 3 million new cases of breast cancer (BC) are predicted and about 1 million women are expected to die from this pathology. The aim of the study to assess the impact of COVID-19 on the indicators of the oncological service for breast cancer in Kazakhstan. Material and research methods. The main method was a retrospective study using descriptive, analytical methods of biomedical statistics and data of the Ministry of Health of the Republic of Kazakhstan - form No.7 and 35 regarding BC (ICD 10 - C50) for 2011-2020. Results. For 2011-2020 42,376 new cases of BC and 12,914 deaths from this pathology were registered. The average annual crude incidence rate was 46.4+or-1.10/0000 (95%CI=44.3-48.5), and increased from 40.8+or-0.70/0000 (2011) to 51 .3+or-0.70/0000 in 2019 and then decrease to 44.2+or-0.70/0000 in 2020 (p<0.001). In dynamics, mortality rates tended to (p<0.001) decrease from 16.1+or-0.40/0000 (2009) to 11.9+or-0.40/0000 in 2019 and 11.5+or- 0.40/0000 in 2020, and the average annual crude mortality rate was 14.2+or-0.60/0000 (95%CI=13.1-15.3). Indicators of early diagnosis (stage I-II) improved from 73.4% (2011) to 86.9% in 2019, and decreased to 84.2% in 2020. Proportion of patients with stage III decreased (from 20.9% in 2011 to 8.4% in 2019 and to 10.0% in 2020) and stage IV (from 5.6% to 4.2% and 5.0%, respectively), i.e. neglect rates are declining. The indicators of morphological verification improved from 95.7% to 99.4% over the years. Conclusions. As a result of the analysis, an improvement in the indicators of morphological verification, early diagnosis, a decrease in the neglect and mortality rates were established. The trends in 2011-2019 differed significantly from the period from 2011-2020, which is due to the COVID-19 pandemic on the registration of BC.
RESUMO
BACKGROUND: A common secondary effect after SARS-CoV-2 immunization is an increased in size of the axillary lymph nodes ipsilateral to the vaccinated site. Eventually, an increased in size of the axillary lymph nodes may lead to a misinterpretation of the breast screening mammogram, performed in asymptomatic women between the age 50 to 69 years old for early breast cancer diagnosis. The aim of our research was to evaluate the impact of the vaccination for SARS-CoV-2 in the breast screening programmes in terms of recall rates and number of false positive results. As a secondary purpose we would analysed the protocols adopted by different breast screening units around the world after SARS-CoV-2 vaccination. METHODS: Observational and retrospective study analysing breast screening mammograms from a single Breast Cancer Screening Unit in Madrid. The mammograms of previously vaccinated women were analysed, reviewing the axillary lymph nodes and the re-call rate secondary to axillary lymphadenopathies. RESULTS: Four hundred and twenty three screening mammograms were performed in May 2021 in the University Hospital Ramon y Cajal in Madrid, which is part of the Breast Screening Programme in Madrid, Spain. None of the women previously vaccinated for SARS-CoV-2 were recalled for complementary studies due to an increased in the axillary lymph nodes. CONCLUSIONS: The protocol stablished by the Spanish Society of Breast Image that stands up for a routine breast screening mammogram after SARS-CoV-2 immunization, has no increase in the recall rate or increase in number of false positives.
RESUMO
State of the matterDue to the COVID-19 pandemic, and the resulting bottlenecks in the French healthcare system, the management of patients with COVID-19 has been prioritized over that of patients with other pathologies, in particular chronic diseases. The objective of this study was to investigate the impact of COVID-19 on the discovery stage of cancers diagnosed in an organized breast cancer screening program, as well as the impact on the time to supported. Material and methodsAll women aged 50 to 74 for whom cancer has been diagnosed in Cote d'Or as part of the national organized breast cancer screening program (first or second reading) from January 1, 2019 to December 31, 2020 have were included in this study. Using data from pathological anatomy laboratories, clinical centers, and the breast and gynecological cancer registry in Cote d'Or, France, we collected sociodemographic, clinical, and treatment data from all patients. We compared data from the year 2019 (pre-COVID) with that of the year 2020 (COVID). ResultsIn this study, we did not observe any change in the stage of discovery of the cancer at the time of diagnosis, nor any change in the therapeutic strategy. However, we observed a significant increase in infiltrated tumors, a decrease in in situ tumors, and the finding of larger clinical size of in situ tumors after the COVID pandemic. ConclusionWhile these results are reassuring, continued monitoring is needed to determine post-pandemic effects.
RESUMO
Background: COVID-19 pandemic brought pressure to Portuguese National Health Service (NHS). We aim to assess pandemic impact on diagnosis and management of breast cancer (BC) in a high-volume Portuguese comprehensive cancer centre, which was classified as a COVID-free institution by public health authorities.
RESUMO
Background: Cancer patients are more sensitive to infection induced by SARS-CoV-2, especially ones with impaired immune response. Vaccines are approved as safe and effective, and they are recommended in oncology patients. The aim of our study was to see the percentage of reinfections after second dose of vaccines against SARS-CoV2.
RESUMO
Background: The COVID-19 pandemic has led to more than 260 million infections and 55 million deaths as of early December 2021, worldwide. Vaccinating people against COVID-19 is considered as he best approach to overcome the pandemic since COVID 19-vaccines are effective and can reduce the risk of getting and spreading the virus. However, their efficacy and safety in patients with underlying disease such as cancers have not been approved yet. Here we report a cohort study on immunogenicity and safety of the inactivated SARS-CoV-2 vaccine (BBIBP-CorV) in patients with breast cancer, who were vaccinated as a part of a national plan for vaccination of patients with special diseases.
RESUMO
Background: COVID-19 has impacted every aspect of our lives. Flooding of hospitals with COVID-19 patients have affected quality of care given to breast cancer patients. Our aim is to assess the impact of COVID-19 on presenting cases of breast cancer and worsening of breast cancer stage and/or TNM classification.
RESUMO
Background: Breast cancer (BC) ranks first in the structure of cancer incidence among women in Kazakhstan. Mammography screening was implemented in 2008. Lockdowns and restrictive procedures with the full and partial cancellation of screening, took place in Kazakhstan in 2020-2021.
RESUMO
Background: The epidemic start of Coronavirus disease it expanded in the first months of 2020. Italy was among the first European countries to be affected and those affected more intensely: the first case was reported on 02.20.2020 The entire health system has been disrupted and reorganized due to the impact of the pandemic on hospitals The suspension of first-level screening services in Italy occurred in the months of March and April 2020 on throughout the national territory, starting from May 2020 the screening programs were reactivated albeit with different timing and intensity between the regions and within of each single region.
RESUMO
Background: COVID-19 pandemic motivated a reorganization of healthcare institutions, which may have led to a negative impact on cancer patients' treatment. This study compared the pathological response (PR) rate to neoadjuvant chemotherapy (NACT) in breast cancer (BC) patients who underwent treatment before (BCv) and during (DCv) the COVID-19 pandemic at our institution.
RESUMO
Objective: All equipment and personnel used in the healthcare field during the COVID-19 pandemic may need to be used for the isolation, diagnosis and treatment of pandemic patients. So we think that there may have been some delays in surgical treatment in the oncological patient group during the pandemic period. For this reason, we aimed to compare the demographic and clinicopathological characteristics of patients who were operated with the diagnosis of breast cancer before and during the pandemic in our center. Material and Method: The study was retrospectively designed at Eskisehir Osmangazi University Hospital General Surgery Clinic. Demographic and clinicopathological data of all patients who were operated for breast cancer 9 months before and 9 months after the declaration of the pandemic were retrospectively analyzed and compared statistically.
RESUMO
Background: Coronavirus disease 2019 (COVID-19) has spread rapidly across the globe through coughing, sneezing, droplet inhalation, and contact. Objectives: The current study aimed to assess the impact of the fear of COVID-19 infection on functionality in women with breast cancer.
