Project description:Screening programs have been associated with a substantial reduction in colorectal cancer (CRC) mortality through endoscopic resection of preneoplastic lesions and detection of early-stage invasive cancers.
In March 2020, the World Health Organization declared as a pandemic the outbreak of coronavirus disease 2019 (COVID-19), caused by SARS-CoV-2. Since then, the SARS-CoV-2 have never stopped spreading, causing an unprecedented situation with highly restrictive considerations to be adopted by the majority of countries worldwide.
Health-care facilities have been making an enormous effort to assist patients affected by COVID-19, while adopting measures to maintain a safe environment for patients and healthcare professionals. As a result, the usual workflow in endoscopy departments changed dramatically, leading to an increase in cancelled procedures, probably increasing the future burden of Colorectal Cancer due to delays in diagnosis.

Project description:Background & aimsThe World Health Organization (WHO) HBV and HCV elimination targets, set in 2016 and based on projections to 2030, were unable to consider the impact of intervening factors. To evaluate the impact of the COVID-19 pandemic on viral hepatitis elimination programs, the European Association for the Study of the Liver (EASL) conducted a survey in liver centers worldwide in 2021.MethodsA web-based questionnaire was distributed (May-July 2021) to all EASL members representing clinical units providing HBV and HCV hepatitis care. Results are expressed as absolute numbers and reduction rates for each care activity.ResultsData were collected from 32 European and 12 non-European clinical centers. Between January 2019 (pre-pandemic) and December 2020 (during the pandemic), chronic HBV consultations decreased by 32% and 26%, new referrals by 38% and 39%, HBV testing rates by 39% and 21% (for HBsAg detection) and 30% and 22% (for HBV DNA detection), and new HBV treatments by 20% and 44% (p = 0.328) in European and non-European centers, respectively. With regard to HCV during the same time frame, the overall reductions were 39% and 50% for consultations, 49% and 49% for new referrals, 11% and 38% for HCV RNA detection, and 51% and 54% for new HCV antiviral treatments for European and non-European Centers, respectively (p = 0.071).ConclusionsAll steps in the viral hepatitis care cascade have been hampered by the COVID-19 pandemic, with a comparable impact across different centers. These data reaffirm the pandemic's major effect on global viral hepatitis elimination programs and suggest that actions to achieve the WHO 2030 targets should be reconsidered and revised to account for each country's progress relative to pre-pandemic values.Lay summaryThe EASL multinational survey conclusively shows that viral hepatitis elimination programs, expected to provide control of hepatitis B and hepatitis C worldwide by 2030, have been held back by the COVID-19 pandemic in clinical centers from several European and non-European countries, with a comparable impact across centers. Limitations in the cascade of care for both HBV and HCV were linked to limited access to screening, consultations, specific testing, and actual treatment. As restrictions for COVID-19 begin to lift, efforts to diagnose and provide treatment for viral hepatitis should remain high on the list of priorities for public health officials to maintain the WHO elimination efforts. Measures that have been put in place to control the COVID-19 pandemic could be transferred to increasing the diagnosis and linkage to care of people with hepatitis.

Project description:Background: In 2014, the World Health Organization (WHO) launched the “post-2015 End TB strategy”, that aims to end the global tuberculosis (TB) epidemic by 2030. However, the COVID-19 pandemic has severely impacted global public health and the strict measures to control the coronavirus spread can affect the management of other diseases, such as TB. Herein, we aimed to assess the impact of the COVID-19 pandemic on the diagnosis of TB in Brazil, during 2020. Methods: We carried out an ecological and population-based study, using spatial analysis techniques. The variables used were the new cases of TB, pulmonary tuberculosis (PTB), and also baciloscopy-positive (BP) cases in Brazil between 2015 and 2020. The percentage of changes (% change) was calculated to verify if there was an increase or decrease of TB cases in 2020, along with time trend analyses given by Joinpoint regression model. Also, interrupted time series analyses were used to assess the trend of TB diagnosis before and after the onset of the COVID-19 in Brazil. Spatial distribution maps were elaborated, considering the % change of each Brazilian state. Findings: Data analyses showed a reduction in the diagnosis of TB (−8.3%) and PTB (−8.1%) in Brazil after the irruption of the COVID-19 pandemic. Likewise, 22 states depicted a reduction in TB diagnosis. An expressive reduction of BP cases (−17.1%) was also observed. Interestingly, interrupted time series analysis showed decline in TB and PTB diagnoses from March 2020. Spatial analyses revealed that all states had a progressive reduction of TB, PTB and PB cases, from March on, with the highest percentages of reduction in December (−100% to −75%). Interpretation: Taken together, our analyses demonstrated a reduction in TB diagnosis after the irruption of the COVID-19 pandemic in Brazil and its regions, signaling a serious impact on the WHO “End TB Strategy” global plan.

Project description:Background & aimsCoronavirus disease 2019 (COVID-19) has placed a significant strain on national healthcare systems at a critical moment in the context of hepatitis elimination. Mathematical models can be used to evaluate the possible impact of programmatic delays on hepatitis disease burden. The objective of this analysis was to evaluate the incremental change in HCV liver-related deaths and liver cancer, following a 3-month, 6-month, or 1-year hiatus in hepatitis elimination programs.MethodsPreviously developed models were adapted for 110 countries to include a status quo or 'no delay' scenario and a '1-year delay' scenario assuming significant disruption in interventions (screening, diagnosis, and treatment) in the year 2020. Annual country-level model outcomes were extracted, and weighted averages were used to calculate regional (WHO and World Bank Income Group) and global estimates from 2020 to 2030. The incremental annual change in outcomes was calculated by subtracting the 'no-delay' estimates from the '1-year delay' estimates.ResultsThe '1-year delay' scenario resulted in 44,800 (95% uncertainty interval [UI]: 43,800-49,300) excess hepatocellular carcinoma cases and 72,300 (95% UI: 70,600-79,400) excess liver-related deaths, relative to the 'no-delay' scenario globally, from 2020 to 2030. Most missed treatments would be in lower-middle income countries, whereas most excess hepatocellular carcinoma and liver-related deaths would be among high-income countries.ConclusionsThe impact of COVID-19 extends beyond the direct morbidity and mortality associated with exposure and infection. To mitigate the impact on viral hepatitis programming and reduce excess mortality from delayed treatment, policy makers should prioritize hepatitis programs as soon as it becomes safe to do so.Lay summaryCOVID-19 has resulted in many hepatitis elimination programs slowing or stopping altogether. A 1-year delay in hepatitis diagnosis and treatment could result in an additional 44,800 liver cancers and 72,300 deaths from HCV globally by 2030. Countries have committed to hepatitis elimination by 2030, so attention should shift back to hepatitis programming as soon as it becomes appropriate to do so.

Project description:The COVID-19 pandemic necessitates healthcare restrictions that also affected ongoing hepatitis C virus (HCV) elimination efforts. We assessed the value of a physician-operated HCV hotline on treatment and cure rates throughout the pandemic. All HCV patients undergoing HCV therapy at the Vienna General Hospital from 2019 to 2021 were included. An HCV hotline was established in 2019 and provided services including phone calls, text messages and voicemails. Patients were stratified by date of HCV therapy: 2019 (pre-COVID) vs. 2020/2021 (during-COVID) and use of the HCV hotline: users vs. non-users. Overall, 220 patients were included (pre-COVID: n = 91 vs. during-COVID: n = 129). The prevalence of intravenous drug use (60.5%) and alcohol abuse (24.8%) was high during COVID. During COVID, the number of DAA treatment starts declined by 24.2% (n = 69) in 2020 and by 34.1% (n = 60) in 2021 vs. pre-COVID (n = 91, 100%). Significantly more patients used the HCV hotline during-COVID (95.3%) vs. pre-COVID (65.9%; p < .001). Sustained virologic response (SVR) was 84.6% pre-COVID and 86.0% during-COVID. HCV hotline users achieved higher SVR rates during-COVID (88.2% vs. 33.3%, p = .004), but also pre-COVID (96.7% vs. 61.3%, p < .001) compared with non-users. Considering only patients with completed DAA treatments, SVR rates remained similarly high during-COVID (96.9%) versus pre-COVID (98.1%). HCV treatment initiations decreased during-COVID but importantly, nearly all DAA-treated HCV patients used the HCV hotline during the COVID pandemic. Overall, the SVR rate remained at 88.2% during COVID and was particularly high in HCV phone users-most likely due to facilitation of adherence.

Project description:BackgroundThe COVID-19 pandemic has disrupted cancer services globally. New Zealand has pursued an elimination strategy to COVID-19, reducing (but not eliminating) this disruption. Early in the pandemic, our national Cancer Control Agency (Te Aho o Te Kahu) began monitoring and reporting on service access to inform national and regional decision-making. In this manuscript we use high-quality, national-level data to describe changes in cancer registrations, diagnosis and treatment over the course of New Zealand's response to COVID-19.MethodsData were sourced (2018-2020) from national collections, including cancer registrations, inpatient hospitalisations and outpatient events. Cancer registrations, diagnostic testing (gastrointestinal endoscopy), surgery (colorectal, lung and prostate surgeries), medical oncology access (first specialist appointments [FSAs] and intravenous chemotherapy attendances) and radiation oncology access (FSAs and megavoltage attendances) were extracted. Descriptive analyses of count data were performed, stratified by ethnicity (Indigenous Māori, Pacific Island, non-Māori/non-Pacific).FindingsCompared to 2018-2019, there was a 40% decline in cancer registrations during New Zealand's national shutdown in March-April 2020, increasing back to pre-shutdown levels over subsequent months. While there was a sharp decline in endoscopies, pre-shutdown volumes were achieved again by August. The impact on cancer surgery and medical oncology has been minimal, but there has been an 8% year-to-date decrease in radiation therapy attendances. With the exception of lung cancer, there is no evidence that existing inequities in service access between ethnic groups have been exacerbated by COVID-19.InterpretationThe impact of COVID-19 on cancer care in New Zealand has been largely mitigated. The New Zealand experience may provide other agencies or organisations with a sense of the impact of the COVID-19 pandemic on cancer services within a country that has actively pursued elimination of COVID-19.FundingData were provided by New Zealand's Ministry of Health, and analyses completed by Te Aho o Te Kahu staff.

Project description:BackgroundAlongside the SARS-CoV-2 (COVID-19) pandemic, Brazil also faces an ongoing rise in cancer burden. In 2020, there were approximately 592 000 new cancer cases and 260 000 cancer deaths. Considering the heterogeneities across Brazil, this study aimed to estimate the impact of the COVID-19 pandemic on cancer-related hospital admissions at a national and regional level.MethodsThe national, regional, and state-specific monthly average of cancer-related hospital admission rates per 100 000 inhabitants and 95% confidence intervals (95% CIs) were calculated from March to July (2019: pre-COVID-19; and 2020: COVID-19 period). Thematic maps were constructed to compare the rates between periods and regions.ResultsCancer-related hospital admissions were reduced by 26% and 28% for clinical and surgical purposes, respectively. In Brazil, the average hospitalization rates decreased from 13.9 in 2019 to 10.2 in 2020 per 100,000 inhabitants, representing a rate difference of -3.7 (per 100,000 inhabitants; 95% CI: -3.9 to -3.5) for cancer-related (clinical) hospital admissions. Surgical hospital admissions showed a rate decline of -5.8 per 100,000 (95% CI: -6.0 to -5.5). The reduction in cancer-related admissions for the surgical procedure varies across regions ranging between -2.2 and -10.8 per 100 000 inhabitants, with the most significant decrease observed in the south and southeastern Brazil.ConclusionsWe observed a substantial decrease in cancer-related hospital admissions during the COVID-19 pandemic with marked differences across regions. Delays in treatment may negatively impact cancer survival in the future; hence, cancer control strategies to mitigate the impact are needed.
