RESUMO

For sustainable food production. In agriculture, crop yields are increasingly affected by warmer temperatures, and pest infestations caused by climate change have increased agricultural losses. Increasing local production is important to reduce our dependence on imported food and provide a buffer in case of supply disruptions such as those caused by the COVID-19 pandemic. To increase food security, it is important to optimize agricultural yields, despite the high costs associated with factors such as supplemental feeding, pest control measures, or operating costs. We present a Machine Vision method (MV) with Adversarial Autoencoder (AAE) as an approach to crop yield optimization. Predicted leaf area is projected from initial germination to early vegetative stages. Generative machine learning models are analyzed to determine a suitable architecture for crop yield prediction. Images of romaine lettuce grown over time under different conditions (e.g., light intensity) are used as the data set. Preliminary results show that the model created is able to predict an image with sufficient accuracy based on a single condition. With our method, corrective actions can be taken early, and yields recover from initial below-average values. Further work can be done to extend the model to other conditions such as moisture, strength of available sunlight, or soil nutrient content.

RESUMO

Aims: The STT pathway was borne out of the National Cancer Strategy 2015 and faster diagnosis standard to rule in, or out, cancer within 28 days of referral. We aimed to review local target standard of practice, including comparison of STT vs Traditional pathways towards reaching the national standards. Methods: The Somerset Database for all target referrals to the department was accessed. We chose October 2019 as a period unaffected by COVID-19. Time to investigation, results and treatment were reviewed. SPSS v.16 was used to perform an unpaired T-test of Traditional vs. STT time to diagnosis. Results: 212 patients were referred for target investigations. 53 declined, DNA-ed or were unfit. 159 proceeded to investigations of which 7 cancers were diagnosed: 4 colorectal, 1 gastric and 2 lung. Time to diagnosis averaged 45.8 days and only 47/159 (29.6%) had their definitive diagnosis in 28 days. 52 patients were streamed to STT and 107 traditional pathways. STT patients were diagnosed at 36.3 days (95% CI 28.1- 44.6) and traditional patients 50.5 days (95% CI 45.4-55.7) (P=0.005). Cancer treatment was received median day 59 (range 27-189) and 4/7 received this within 62 days. Conclusion: Target investigations have low pick up rates of cancers with ever increasing referrals. Our centre did not meet aspirational national targets of time to treatment or diagnosis, although STT patients were diagnosed significantly faster. With COVID-19, rationalisation of patient contact with maintained diagnosis rates must be strategised. Stricter FIT testing with risk stratification and STT expansion is one strategy.

RESUMO

Background: Increased hepatitis C virus (HCV) testing among people in prison (PIP) is key for HCV elimination efforts to be successful. Efforts to improve health care in all British Columbia (BC) Provincial Correctional Centres (PCCs) have been made in recent years, beginning with the transfer of health services from BC Corrections to BC Provincial Health Services Authority (PHSA) in 2017. However, the state of emergency declared in BC in early 2020 in response to the COVID-19 pandemic may have undermined these efforts. This study aims to examine patterns in HCV screening and diagnosis in all 10 BC PCCs before and during the COVID-19 pandemic. Methods: Data from the BC Sexually Transmitted and Blood-Borne Infections Data Mart, which contains laboratory data accounting for >95% of all anti-HCV and >99% of all HCV RNA and genotype tests performed in BC, were used for this study. The number of anti-HCV, HCV RNA and HCV genotype tests that were ordered from BC PCCs between April 1 2011 and March 31 2021 was determined for quarterly periods. New HCV diagnoses were defined as the number of 1st-time HCV-positive test episodes (anti-HCV, RNA or genotype) among HCV tests ordered from BC PCCs. Total intake numbers were provided by BC Corrections per calendar year. Results: The number of HCV antibody, RNA, and genotype tests ordered from BC PCCs in the 1st quarter of 2020 had increased by 412% (n=486), 530% (n=252) and 827% (n=139) respectively (Figure 1), compared to the 1st quarter of 2017 (prior to the transfer of health services to PHSA). Following the beginning of the COVID-19 pandemic, the number of HCV antibody, RNA, and genotype tests ordered from BC PCCs in the 2nd quarter of 2020 had decreased by 66% (n=165), 67% (n=83) and 68% (n=44), respectively (Figure 1), compared to the 1st quarter of 2020. The total number of HCV tests as a proportion of intakes to BC PCCs in 2019 was 17% (2518/15303), which increased to 23% (2112/9283) in 2020. Conclusion: The transfer of health services in BC PCCs to PHSA led to increased volume of HCV screening, with concomitant increases in new HCV diagnoses among PIP in BC from 4th quarter 2017 onwards. The COVID-19 pandemic led to health care challenges in prisons in BC (including the suspension of non-urgent HCV testing in the entire province for several weeks), and at the same time, the number of HCV tests and new diagnoses decreased. This may have been partly due to reduced intakes to BC PCCs over 2020, as the total number of HCV tests ordered as a proportion of intakes increased in 2020, compared to the previous year. Those people diverted away from the correctional system due to decarceration efforts triggered by COVID-19 may have missed out on HCV screening during 2020, therefore further efforts to increase HCV screening in correctional settings and the community will be needed.
