Acupuncture and moxibustion have been actively involved in combating major epidemics such as malaria, schistosomiasis, and COVID-19. This article conducts a historical review of these three significant cases to elucidate how the acupuncture community has effectively utilized its unique advantages and characteristics through theoretical discussions, clinical practices, experimental research, as well as receiving administrative leadership and political support from the Communist Party of China and government. We provide an objective evaluation of their effectiveness while summarizing historical experiences to serve as a reference for future utilization of acupuncture and moxibustion therapy in epidemic relief efforts. Additionally, propose four suggestions: strengthening Party leadership and enhancing political support;timely summarization of experiences to establish programs and systems;deepening scientific research by integrating experimental findings with clinical practice;focusing on public awareness campaigns and education to solidify grassroots foundations.展开更多

However, these factors can change, depending on the characteristics of the population and health services. In this sense, longitudinal studies can be useful for understanding local realities and subsidizing health actions based on these realities. Objective: To analyze the risk factors for severity and death in hospitalized patients with COVID-19. Methods: A retrospective cohort of patients with COVID-19 hospitalized from August 1 to October 16, 2021 (3<sup>rd</sup> wave of the pandemic), notified by the Department of Epidemiological Surveillance of Sao Tome and Principe. We employed measures of strength of associations for the analysis of exposure risk factors. Results: We analyzed 110 hospitalized patients (31.8% severe-critical and 68.2% non-severe). The risk factors for severe forms of COVID-19 were: being aged ≥60 years (RR = 3.3), being male (RR = 2), having comorbidities (RR = 2) and the risk increases to 10-fold for multicomorbidities, with emphasis on obesity, neoplasia, skin-muscle-surgical infection, dementia and to some degree CVD. 62.9% of patients with severe forms of the disease were not vaccinated. Risk factors for death among hospitalized and severe/critical cases, respectively, were having comorbidities (RR = 8 and 2.4) multicomorbidities (RR = 10 and 2.8 for those with 2 comorbidities and RR = 33.3 and 4 for those with 3 or 4 comorbidities), especially diabetes, dementia, neoplasia, cutaneous-muscular infection, and obesity. Although CVD was not associated with risk factors for death, these were the most frequently found among the severely hospitalized and deaths. In addition, important risk factors associated with death were not using corticoids (RR = 3.3, 230-fold risk) and not using anticoagulants-heparin (RR = 1.3, 30% risk) more compared to the severe cases that did use them. Most of the patients who died (63.2%) were not vaccinated. Moreover, having only 1 dose of the vaccine was a risk factor 1.9 times more for death among all hospitalized patients, but in the severe cases, there was no association between the variable vaccination and death. Among those hospitalized with 2 doses, it was a 0.5-fold protective factor among those hospitalized. The Delta variant of Sarscov-2 was the one found among severe cases and deaths investigated by genetic sequencing, with more exuberant clinical features compared to the other 2 previous vaccinations. Conclusion: Being elderly, male and presenting comorbidities, mainly multicomorbidities were the main characteristics associated with severity of COVID-19. On the other hand, comorbidities, and even worse, multicomorbidities, hospitalization for respiratory failure, lowered level of consciousness, no use of corticoid and no use of anticoagulation in critically ill patients, and not having at least 2 doses of vaccine for covid-19, were characteristics associated with death by COVID-19. These results will help inform healthcare providers so that the best interventions can be implemented to improve outcomes for patients with COVID-19. Public health interventions must be carefully tailored and implemented in these susceptible groups to reduce the risk of mortality in patients with COVID-19 and then the risk of major complications. Intensive and regular follow-up is needed to detect early occurrences of clinical conditions.展开更多

It may cause undershoot, which causes rebounds and assists survival of the pathogen. <strong>Conclusions:</strong> Partial easing levels, even low levels for economic relief while waiting on a vaccine, have population immunity thresholds based on the reduced replication rates and may experience overshoot as well. We further find a two-step strategy remains highly sensitive to variations in case ratio, replication factor, seasonality and timing. We demonstrate a three or more step strategy is more robust, and conclude that the best possible approach minimizes deaths under a range of likely actual conditions which include public response.展开更多

Here, “3” stands for the epidemic prevention and control system, personnel management, and prevention and control measures;“1” stands for COVID-19 testing.<strong> Result: </strong>From March 1, 2020 to March 31, 2021, a total of 3056 patients were hospitalized in the three infection wards. Among them, 265 patients had a fever, and 113 patients had respiratory symptoms. None of them were infected with COVID-19. The participation rate of the test about the knowledge related to COVID-19 and the knowledge mastery rate were both 100% among the medical staff. None of the inpatients and their companions or the medical staff was diagnosed with COVID-19.<strong> Conclusion: </strong>Thus the “3 + 1” mode proves successful for avoiding nosocomial infection and the spread of the epidemic.展开更多

This epidemic is now on the period of global outbreak, the control of COVID-19 has severely challenged the world. At the beginning of the outbreak, patients infected or suspected were observed and close contacts were isolated. The country delayed the resumption of work and school and all walks of life are seriously affected. All kinds of true and false information and rumours on the internet exist, aggravating people’s anxiety and restlessness. These factors altogether often induce people to feel various negative emotions and psychological problems. In this paper, a patient with COVID-19 was examined through psychological dynamic observation at the beginning of the epidemic. It was found that in the early stage of the epidemic, due to the lack of clear treatment guidelines, the main treatment methods and psychological problems were the main reasons affecting the recovery of patients. Many uncertain factors, including individual and social factors and quarantine, worry about the prognosis, etc, resulting in anxiety, fear, unacceptance, insomnia, irritability and other pessimistic moods. After 16 days of symptomatic treatment, psychological counselling and adjustments in a timely manner, the patient eventually recovered and was discharged. The discussion of this case could serve as a reference for the treatment and rehabilitation of patients with COVID-19 in other countries and regions.展开更多

文摘<strong>Objective:</strong> We assess the application effect of the “3 + 1” mode in the COVID-19 epidemic prevention and control at the infection ward of a designated comprehensive hospital for COVID-19 treatment.<strong> Method: </strong>Based on the features of the inpatients of the infection ward and their relatives, a “3 + 1” mode for the COVID-19 prevention and control is developed to conform to the demands for epidemic prevention and control and the overall prevention and control scheme of the whole hospital. Here, “3” stands for the epidemic prevention and control system, personnel management, and prevention and control measures;“1” stands for COVID-19 testing.<strong> Result: </strong>From March 1, 2020 to March 31, 2021, a total of 3056 patients were hospitalized in the three infection wards. Among them, 265 patients had a fever, and 113 patients had respiratory symptoms. None of them were infected with COVID-19. The participation rate of the test about the knowledge related to COVID-19 and the knowledge mastery rate were both 100% among the medical staff. None of the inpatients and their companions or the medical staff was diagnosed with COVID-19.<strong> Conclusion: </strong>Thus the “3 + 1” mode proves successful for avoiding nosocomial infection and the spread of the epidemic.

文摘BACKGROUND Coronavirus disease 2019(COVID-19)is an emerging,rapidly evolving disease that spreads through the respiratory system and is highly contagious.In March 2020,the World Health Organization declared the COVID-19 outbreak a pandemic.In China,the pandemic was controlled after 2 mo through effective policies and containment measures.Describing the detailed policies and containment measures used to control the epidemic in Chongqing will provide a reference for the prevention and control of COVID-19 in other areas of the world.AIM To explore the effects of different policies and containment measures on the control of the COVID-19 epidemic in Chongqing.METHODS Epidemiological data on COVID-19 in Chongqing were prospectively collected from January 21 to March 15,2020.The policies and prevention measures implemented by the government during the epidemic period were also collected.Trend analysis was performed to explore the impact of the main policy measures on the effectiveness of the control of COVID-19 in Chongqing.As of March 15,the cumulative incidence of COVID-19 in Chongqing was 1.84/100000(576 cases)and the infection fatality rate was 1.04%(6/576).The spread of COVID-19 was controlled by effective policies that involved establishing a group for directing the COVID-19 epidemic control effort;strengthening guidance and supervision;ensuring the supply of daily necessities and medical supplies and equipment to residents;setting up designated hospitals;implementing legal measures;and enhancing health education.Medical techniques were implemented to improve the recovery rate and control the epidemic.Policies such as“the lockdown of Wuhan”,“initiating a first-level response to major public health emergencies”,and“implementing the closed management of residential communities”significantly curbed the spread of COVID-19.Optimizing the diagnosis process,shortening the diagnosis time,and constructing teams of clinical experts facilitated the provision of“one team of medical experts for each patient”treatment for severe patients,which significantly improved the recovery rate and reduced the infection fatality rate.CONCLUSION The prevention policies and containment measures implemented by the government and medical institutions are highly effective in controlling the spread of the epidemic and increasing the recovery rate of COVID-19 patients.
文摘Epidemics spread quickly and are highly contagious.And there has been a profound understanding of etiology,pathogenesis,prevention,and treatment of these diseases in traditional Chinese medicine(TCM).Coronavirus disease 2019(COVID‑19)falls into the category of“epidemic dampness”,and the core pathogenesis is that latency of externally‑contracted dampness turbidity and epidemic toxin in pleurodiaphragmatic interspace provokes Shaoyang ministerial fire and causes concomitant attack of external and internal pathogens,resulting in wood fire tormenting metal and the upward rushing of dampness fire(toxin),ultimately leading to a syndrome of epidemic toxin blocking the lung.Throughout the treatment of COVID‑19,Professor Shiyun Yan uses the“harmonizing”method and sticks to the basic principles of“protecting middle qi,pectoral qi and yin fluid”to consolidate the root,dispersing externally and clearing internally and using in combination drugs cold and warm in property.The specific treatment approaches include ventilating lung and expelling pathogens,clearing heat and removing the toxin,tonifying qi and nourishing yin,activating blood and resolving stasis,resolving dampness,and dredging collaterals,to prevent the patient’s condition from getting worse and save the dying.

文摘Coronavirus disease-2019 (COVID-19) caused by novel coronavirus 2019 (2019-nCoV) has led to 199,466,211 confirmed cases, including 4,244,541 deaths by 6:44 pm CEST. This epidemic is now on the period of global outbreak, the control of COVID-19 has severely challenged the world. At the beginning of the outbreak, patients infected or suspected were observed and close contacts were isolated. The country delayed the resumption of work and school and all walks of life are seriously affected. All kinds of true and false information and rumours on the internet exist, aggravating people’s anxiety and restlessness. These factors altogether often induce people to feel various negative emotions and psychological problems. In this paper, a patient with COVID-19 was examined through psychological dynamic observation at the beginning of the epidemic. It was found that in the early stage of the epidemic, due to the lack of clear treatment guidelines, the main treatment methods and psychological problems were the main reasons affecting the recovery of patients. Many uncertain factors, including individual and social factors and quarantine, worry about the prognosis, etc, resulting in anxiety, fear, unacceptance, insomnia, irritability and other pessimistic moods. After 16 days of symptomatic treatment, psychological counselling and adjustments in a timely manner, the patient eventually recovered and was discharged. The discussion of this case could serve as a reference for the treatment and rehabilitation of patients with COVID-19 in other countries and regions.
文摘Epidemic diseases,known and studied in China since antiquity,are one of the main chapters of the School of Exogenous Febrile Diseases(温病学派)•Along with the legends about epidemic demons,China has developed over the centuries a medical approach based on the teachings of Huang Di Nei Jing(《黄帝内经》Internal Classic),Nan Jing(《难经》Classic of Difficulties'),and Shang Han Lun(《伤寒论》Treatise of Harmful Cold).However,it was in the 17th century,after the great break of the Song,Jin,and Yuan eras that an innovative spirit Wu Youxing(吴有性)first foresaw the existence of microorganisms as we know them now.His Wen Yi Lun(《瘟疫论》Treatise on Pestilences)foreshadows an original approach to epidemic diseases,particularly emerging infectious diseases of the 21st century:severe acute respiratory syndrome 2003-2004 and the COVID-19 pandemic are perfect examples.In this first article,which will be followed by two others,we will examine the classical and modern Chinese definitions of these dreadful plagues.
文摘Along with the legends about epidemic demons,China has developed over the centuries a medical approach to epidemic diseases based on the teachings of Hucng Di Nei Jing(《黄帝内经》Huangdi s Intermnal Classic),Nan Jing(《难经》Classic of Difficult Issues),and Shang Han Lun(《伤寒论》Treatise on Cold Damage).Other doctors and scientists participated in this evolution of knowledge,like Wang Shuhe(王叔和),Ge Hong(葛洪),Chao Yuanfang(巢元方),Sun Simiao(孙思邈),and Liu Wansu(刘完素).However,it was in the 17^th century,after the great break of the Song,Jin,and Yuan eras that an innovative spirit,Wu Youke(吴又可1582-1652)first foresaw the existence of microorganisms as we know them now.His Wen Yi Lun(《瘟疫论》Treatise on Pestilence)foreshadows an original approach to epidemic diseases,particularly emerging infectious diseases of the 21^st century.After them,traditional Chinese medicine developed a comprehensive method of diagnosing and treating of these diseases(Epidemic Diseases Theory瘟疫学说)within the School ofHeat Diseases(温病学派).In a third article,we will examine some applications in the treatment of the SARS 2003-2004 epidemic(非典型肺炎)and the current COVID-19(新型冠状病毒肺炎)pandemic.
