Smarter cures to combat COVID-19 and future pathogens: a review

Prevention is better than cure. A milestone of the anthropocene is the emergence of a series of epidemics and pandemics often characterized by the transmission of a pathogen from animals to human in the past two decades. In particular, the coronavirus disease 2019 (COVID-19) has made a profound impact on emergency responding and policy-making in a public health crisis. Classical solutions for controlling the virus, such as travel restrictions, lockdowns, repurposed drugs and vaccines, are socially unpopular and medically limited by the fast mutation and adaptation of the virus. This is exacerbated by microbial resistance to therapeutic drugs and the slowness of vaccine development. In other words, microbial pathogens are somehow 'smarter' and faster than us, thus calling for more intelligent cures to combat future pandemics. Here, we compare therapeutics for COVID-19 such as synthetic drugs, vaccines, antibodies and phages. We present the strength and limitations of antibiotic and antiviral drugs, vaccines, and antibody-based therapeutics. We describe smarter, cheaper and preventive cures such as bacteriophages, food medicine using probiotics and prebiotics, sports, healthy diet, music, yoga, Tai Chi, dance, reading, knitting, cooking and outdoor activities. Some of these preventive cures have been intuitively developed since thousands of years ago, as illustrated by the fascinating similarity of the Chinese characters for 'music' and 'herbal medicine.'

Public attitudes toward traditional Chinese medicine and how they affect medical treatment choices in Hong Kong

Purpose

This study aims to test a conceptual model using public attitudes toward biomedicine and traditional Chinese medicine (TCM) to predict respondents’ medical treatment choice.

Design/methodology/approach

A quantitative online survey was conducted using quota sampling. Altogether 1,321 questionnaires from Hong Kong residents of age 15 years or above were collected.

Findings

Attitudes toward biomedicine in relation to TCM and perceived cost of TCM consultation were found to be significant variables in predicting respondents’ medical treatment choice of treatment. Perceived efficacy of TCM, however, was not a significant predictor. Older respondents, as well as respondents with higher education, were less likely to consult biomedicine first when ill. They were also less likely to consult biomedicine exclusively.

Research limitations/implications

This study uses a convenience sample recruited through personal networks. The findings cannot be generalized to the rest of the population.

Practical implications

Respondents in the study generally perceived TCM’s efficacy to be high, but not high enough to make it the medical treatment of choice. To promote TCM in Hong Kong, there is a need to enhance trust in it. This can be achieved through strengthening scientific research and development of TCM, enhancing professional standards of TCM practitioners and educating the public about the qualifications of TCM practitioners. Strategic channel planning to reach potential target and reducing the time cost of TCM medication should be examined.

Originality/value

The study is the first to relate attitudes to and perceptions of TCM with medical treatment choices in Hong Kong.

CHINESE HERBAL DECOCTION AS A COMPLEMENTARY THERAPY FOR ATROPHIC GASTRITIS: A SYSTEMATIC REVIEW AND META-ANALYSIS

Background:

Chinese herbal decoction (CHD) has been extensively used in the treatment of atrophic gastritis (AG) in China and other Far Eastern countries. We conducted a systematic review and meta-analysis to estimate the efficacy and safety of CHD in AG.

Materials and Methods:

Pubmed, Embase, Cochrane central register of controlled trials (central), VIP, China National Knowledge Infrastructure, Sinomed, Wanfang data were searched (up to December 2015). Randomized controlled trials recruiting patients with AG comparing CHD (alone or with western medicine (WM)) with WM were eligible. Dichotomous data were pooled to obtain relative risk (RR), with a 95% confidence interval (CI).

Results:

Forty-two articles including 3,874 patients were identified. CHD, used alone or with WM, had beneficial effect over WM in the improvement of clinical manifestations (RR=1.28; 95% CI 1.22-1.34) and pathological change (RR=1.42; 95% CI 1.30-1.54) for AG patients. However, the H. pylori eradication effect of CHD was not supported by the existing clinical evidence, because of the significant study heterogeneity (I²>50%) and inconsistency between the primary results and sensitivity analysis.

Conclusions:

CHD, if prescribed as a complementary therapy to WM, may improve the clinical manifestations and pathological change for AG patients. But its monotherapy for H. pylori eradication is not supported by enough clinical evidence.
