The impact of Victorian COVID-19 lockdowns on the presentation and management of acute appendicitis.

BACKGROUNDS: The COVID-19 pandemic presents ongoing challenges for healthcare. Stay at Home orders ('lockdowns') and community fears have been suggested to create reluctance to seek healthcare. We aimed to determine whether the rates of perforated appendicitis and negative appendicectomy have been affected by the pandemic, and to analyse the effect of lockdowns on the management of acute appendicitis in Victoria. METHODS: We conducted a retrospective audit of emergency appendicectomies performed under adult General Surgery units at Monash Health in Victoria from January 2019 to September 2021, including 242 days of lockdown. RESULTS: 2459 patients were included. Fewer patients had perforated appendicitis during the second lockdown (6.3% versus 10.7% baseline; p = 0.027). The rate of negative appendicectomy was reduced during the first lockdown (4.1% versus 14.9% baseline; p = 0.002) and during intervals between lockdown in 2021 (9.8%; p = 0.010). There was no difference in the rate of perforated appendicitis or negative appendicectomy at other times. Time to surgery and number of appendicectomies performed were also not significantly different. Fewer appendicectomies were performed after hours during lockdowns and in 2021 more generally compared to baseline (p < 0.05). CONCLUSION: The lower negative appendicectomy rate during the first lockdown may reflect increased pre-operative imaging or clinical observation for undifferentiated presentations. There was a reduction in perforated appendicitis during the second lockdown, and no significant difference at other times. Contrary to other studies, lockdowns associated with the COVID-19 pandemic may not create a reluctance to seek healthcare in all regions.

The Global Times and The China Threat Narrative: An Empirical Analysis.

China's Global Times has become more popular in the Australian media than ever, and its editor, Hu Xijin, has also gained worldwide attention. The Global Times presents a nationalistic narrative about China and the world. This study, the first of its kind in the academic literature, examines the relationships between the Global Times narrative and the China threat narrative in Australia and worldwide. By applying time series econometric models to weekly datasets from May 2020 to April 2021, this study finds that the Global Times narrative is significantly associated with the level of the China threat narrative in Australia, and the same is true for the corresponding global relationship. This study makes original and significant contributions to the academic literature and has useful implications for policymakers.

Chinese Influence in Australia: What Do Financial Markets Tell Us?

Australia-China relations, and especially Chinese influence in Australia, have been the subject of heated debate in Australia since 2016. The central issue is, how to balance concerns over Chinese influence in Australia with the economic benefits of Chinese trade and investment? This study-arguably the first of its kind-answers this question using rigorous empirical modelling. First, it uses Google Trends search results to measure Chinese influence in Australia. Second, it connects Chinese influence, as reflected in Google Trends search results, to financial markets, including stock markets, government bond markets and foreign exchange markets. Weekly data for January 2016-December 2019 are entered into an exponential generalised autoregressive conditional heteroskedastic model. The study finds that the effects of concerns over Chinese influence relate mainly to increased volatility of stock market indices and government bond yields, and downward pressure on the share prices of individual firms that are heavily exposed to Chinese markets. However, the overall effects appear to be minor or insignificant. The implications of these results are that China's economic coercion (if any) may not be effective, and Australia's responses to Chinese influence and interference (if any) may generate insignificant costs. Finally, this study makes original and significant academic contributions to academia by providing a novel framework for exploring international relations.
