Clinical efficacy of combination therapy of FuXi-Tiandi-Wuxing Decoction and anti-viral drugs in the treatment of novel coronavirus pneumonia: A prospective interventional study.

Introduction: The National Administration of Traditional Chinese Medicine of the People's Republic of China (NATCM) and the State Administration of Traditional Chinese medicine (TCM) advocated a combination therapy of TCM and anti-viral drugs for novel coronavirus pneumonia (NCP) to improve the efficacy of clinical treatment. Methods: Forty-six patients diagnosed with NCP were sequentially divided into intent-to-treat population: the experimental group (combination of FuXi-Tiandi-Wuxing Decoction and anti-viral drugs; n = 23) and the control group (anti-viral drugs only) (n = 23). The two groups were compared in terms of duration of fever, cough symptom score, fatigue, appetite, dyspnea, out-of-bed activities, chest computer tomography (CT) recovery, virological clearance, average length of hospital stay, and clinical effective rate of drug. After 6 days of observation, patients from the control group were divided into as-treated population: experimental subgroup (n = 14) to obtain clinical benefit and control subgroup (n = 9). Results: There was a significant improvement in the duration of fever (1.087 ± 0.288 vs 4.304 ± 2.490), cough (0.437 ± 0.589 vs 2.435 ± 0.662; P < 0.05), chest CT evaluation (82.6% vs 43.4%; P < 0.05), and virological clearance (60.8% vs 8.7%; P < 0.05) in patients of the experimental group compared with patients in the control group. Further observation in as-treated population reported that cough (0.742 ± 0.463 vs 1.862 ± 0.347; P < 0.05) and fatigue (78.5% vs 33.3%; P < 0.05) were significantly relieved after adding FuXi-Tiandi-Wuxing Decoction to the existing treatment. Conclusion: An early treatment with combination therapy of FuXi-Tiandi-Wuxing Decoction and anti-viral drugs significantly relieves the clinical symptoms of NCP, shows improvement in chest CT scan, improves virological clearance, shortens average length of hospital stay, and reduces the risk of severe illness. The effect of FuXi-Tiandi-Wuxing Decoction in NCP may be clinically important and require further consideration.

Anaemia and associated factors among children aged 6-23 months in agrarian community of Bale zone: a cross-sectional study.

Anaemia remains among the most prevalent nutritional problems among children in developing countries. In Ethiopia, more than half of children <5 years of age are anaemic. In the early stages of life, it leads to poor cognitive performance, delay psychomotor development and decreases working capacity in later life. The present study aimed to assess the prevalence and associated factors of anaemia among children aged 6-23 months in the Bale zone. A community-based cross-sectional study was conducted from 1 to 30 June 2021. Multistage stratified sampling and simple random sampling techniques were employed to select 770 samples. An interviewer-administered questionnaire was used to collect data on socio-demographic, child health and feeding practices. Haemoglobin levels were estimated using a portable Hemosmart machine. Children with haemoglobin values below 11 g/dl were considered anaemic. Binary logistic regression analysis was performed to identify factors associated with anaemia. Statistical significance was set at P < 0⋅05. The prevalence of anaemia was 47⋅9 % (95 % CI (44⋅4, 51⋅5)). The multivariate analysis showed that child age (6-11 months) (AOR 1⋅47; 95 % CI (1⋅06, 2⋅03)), household food insecurity (AOR 1⋅44; 95 % CI (1⋅01, 2⋅04)), having diarrhoea and cough in the past 2 weeks (AOR 1⋅70; 95 % CI (1⋅18, 2⋅44)) and (AOR 1⋅97; 95 % CI (1⋅28, 3⋅04), respectively), not consuming the recommended dietary diversity (AOR 2⋅72; 95 % CI (1⋅96, 3⋅77)) and stunting (AOR 1⋅88; 95 % CI (1⋅31, 2⋅70)) were significantly associated with anaemia. Anaemia in children aged 6-23 months was a severe public health problem in the study area. Integrated nutritional interventions combined with iron fortification and supplementation is recommended.

Nutrition and health-seeking practices during pregnancy and lactation and potential strategies to increase micronutrient intakes among women in northern Lao PDR.

Access to and utilisation of antenatal care (ANC) is important for optimising health and nutrition during pregnancy. This study aimed to assess adherence to and factors associated with ANC and antenatal supplement use among Laotian women, and consider culturally appropriate strategies to increase micronutrient intakes. Mother-child (aged 21 d to <18 months) dyads (n 699) enrolled in a hospital-based prospective cohort study with the community comparison group in Luang Prabang province were interviewed about their antenatal history, supplement use, household sociodemographic and dietary practices, including postpartum food avoidances. Ninety percent of women (mean age 24⋅7 ± 6⋅3 years) reported receiving ANC during their pregnancy, with the majority reporting four to seven contacts, while 84⋅6 and 17⋅3 % reported supplement use during pregnancy and lactation, respectively. Adequate ANC contacts (≥8) and supplement use was more likely among women with complete primary education and from higher socioeconomic status households, and less likely among women belonging to ethnic minority populations and those who delivered their child at home. All women continued to consume salt while adhering to postpartum food avoidances; however, 58⋅5 and 38⋅7 % of habitual consumers restricted fish and soy sauces, respectively. Eighty-six percent of women reported they would be willing to take supplements when adhering to postpartum dietary restrictions. Overall, women's reported ANC attendance and antenatal supplement use was suboptimal. Understanding predictors of and barriers to ANC and supplement use may help implement effective public health strategies to improve adherence. Alongside targeted supplementation, salt fortification with micronutrients may be a viable population-wide intervention that needs further evaluation.

Single domain antibodies derived from ancient animals as broadly neutralizing agents for SARS-CoV-2 and other coronaviruses.

With severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) as an emergent human virus since December 2019, the world population is susceptible to coronavirus disease 2019 (COVID-19). SARS-CoV-2 has higher transmissibility than the previous coronaviruses, associated by the ribonucleic acid (RNA) virus nature with high mutation rate, caused SARS-CoV-2 variants to arise while circulating worldwide. Neutralizing antibodies are identified as immediate and direct-acting therapeutic against COVID-19. Single-domain antibodies (sdAbs), as small biomolecules with non-complex structure and intrinsic stability, can acquire antigen-binding capabilities comparable to conventional antibodies, which serve as an attractive neutralizing solution. SARS-CoV-2 spike protein attaches to human angiotensin-converting enzyme 2 (ACE2) receptor on lung epithelial cells to initiate viral infection, serves as potential therapeutic target. sdAbs have shown broad neutralization towards SARS-CoV-2 with various mutations, effectively stop and prevent infection while efficiently block mutational escape. In addition, sdAbs can be developed into multivalent antibodies or inhaled biotherapeutics against COVID-19.

Correlation between 25-hydroxy vitamin D levels in women and in vitro fertilization outcomes: A cross-sectional study.

Background: Vitamin D has recently raised a great deal of controversy, not because of its traditional role of absorbing calcium and maintaining bone health, but because of its unconventional role as an endocrine factor and the extent of its impact when linked to its specific receptors (VDR) found in different tissues. Research has raced trying to find its different roles in those tissues and its association with different clinical or medical conditions, and among these cases, its role in reproductive functions and fertility in women, these studies conflicted between supporting and denying the role of vitamin D in reproductive function and rejecting this hypothesis according to the results of their study. Materials and methods: The in vitro fertilization process allowed us to study the possible hypotheses, as this technique provides an opportunity to study the relationship between vitamin D levels with the in vitro fertilization outcomes, thus providing us with an idea of the relationship of vitamin D with fertility in women. In order to study this relationship, we designed our research as a cross-sectional study to confirm or deny this claim. Vitamin D was measured in the blood and in the follicular fluid for all cases using the electrochemiluminescence immunoassay (ECLIA) for the assay of total vitamin D, then IVF outcomes were compared with the levels of vitamin D in the blood. Results: the levels of vitamin D are not related to the criteria of eggs such as the number of eggs and the maturity rate (MR) of eggs, but they are correlated in a statistically significant manner with the fertility rate (FR), and at the same time the levels of vitamin D in the blood were completely independent of the clinical pregnancy rate (CPR). Conclusion: blood vitamin D levels will affect the FR when its levels in the blood drop below a specified value, vitamin D did not correlate with the CPR. In the long run, there is scope for more research projects on vitamin D. Future research could include case-control studies of patients on vitamin D supplementation, and the study of its correlation with IVF outcomes.

Synergetic antibacterial activity of Vernonia auriculifera Hiern and Buddleja polystachya Fresen on selected human pathogenic bacteria.

Background: Medicinal plants have been used as traditional treatments for various human diseases for many years and they are still widely practiced throughout the world. Due to the long history of the practice, medicinal plants have become an integral part of the Ethiopian culture. This study aimed to evaluate the antibacterial activities of Vernonia auriculifera Hiern and Buddleja polystachya Fresen leaf extracts and their synergistic effect against some selected human pathogenic bacteria. Methods: Ethanol, methanol, and n-hexane crude extracts of Vernonia auriculifera, Buddleja polystachya, and a mixture of the two-plant respective of each solvent were evaluated against tested pathogenic bacteria using the agar well diffusion method; the inhibition zones were recorded in millimeters. Gentamycin was used as a positive control, while dimethyl sulfoxide served as a negative control. The minimum inhibitory concentration of the plant extracts against test bacteria was evaluated using two-fold broth dilution methods and then Minimum bactericidal concentration was determined by sub-culturing the test dilutions from minimum inhibitory concentration tubes onto fresh Muller Hinton Agar plates incubated at 37 °C for 24 h. Results: Maximum antibacterial inhibition zone was observed on methanol extracts of synergism against S. Typhimurium (ATCC 1333) (31.00 ± 1.73 mm) while, a minimum inhibition zone was observed on methanol extract of Buddleja polystachya, against E. coli (ATCC 35218) (5.67 ± 0.57). Minimum inhibitory concentration and minimum bactericidal concentration values of the crude extracts of Vernonia auriculifera, Buddleja polystachya, and their mixture lies between (3.125%-12.5%) and (6.25%-25%) respectively. The data were analyzed using the SPSS software package version 20 for windows. Conclusion: The present study revealed that ethanol and methanol extracts of Vernonia auriculifera and Buddleja polystachya possess significant inhibitory effects against tested pathogens and the antibacterial activity of both plants leaf extracts was greater than the activity of currently used antibiotics (Gentamycin) against some selected organisms.

Child undernutrition and associated factors among children 6-23 months old in largely food insecure areas of rural Ethiopia.

Child malnutrition is the leading public health problem in Sub-Saharan Africa, resulting in poor health and economic losses. Ethiopia has one of the highest child undernutrition rates in the world that occurs to multifaceted factors, including food insecurity. Thus, we performed a cross-sectional study to assess the prevalence and risk factors for child undernutrition in largely food insecure areas of Ethiopia. Data were collected from 354 mother-child pairs from the Siraro district. Both bivariate and multivariate logistic regression was used for statistical analysis. Variables with a P-value of <0⋅05 in multivariate analysis were used to detect statistical significance at a 95 % confidence level. About 67 % of households are food insecure. The prevalence of stunting wasting and underweight were 42⋅7, 9⋅9 and 27⋅7 %, respectively. Female gender, higher age of the child (12-23 months v. 6-11 months), living in a household with five or more siblings, not getting therapeutic zinc supplement at least once, inadequate diet diversity, lack of growth monitoring service, and maternal own income increases the likelihood of child undernutrition. It can be concluded that child undernutrition is a severe public health problem in the study area. Improving primary healthcare services related to zinc supplementation, growth monitoring and promotion, and improving infant and child feeding practices can be considered as a strategy to address the problem.

Nearly one-in-five mothers avoid colostrum in North Wollo Zone, Ethiopia: an institution-based cross-sectional study.

Colostrum contains antibodies that protect the newborn against disease. Despite this fact, many Ethiopian mothers see colostrum feeding as a cause of neonatal morbidity and mortality. These mothers believe that colostrum must discard to alleviate this effect. However, the cause of this misconception about colostrum was not well researched, particularly in this study area. The main aim of the present study was to assess colostrum avoidance and associated factors among mothers having children aged 6-59 months in North Wollo Zone, Northeastern Ethiopia. An institution-based cross-sectional study design was used. Descriptive statistics, binary and multivariable logistic regression analyses were used for the statistical analysis. The prevalence of colostrum avoidance was 19 % (95 % CI 15⋅03, 22⋅89 %) among mother-child pair aged 6-59 months. In multivariable logistic regression analysis, the most important predictors were breast-feeding initiation Adjusted Odds Ratio (AOR) 6⋅369; 95 %, Confidence Interval (CI) (3⋅067, 13⋅224), pre-lacteal feeding AOR 3⋅464; 95 % CI (1⋅721, 6⋅973), shared household decision about child feeding AOR 3⋅585; 95 % CI (1⋅563, 7⋅226), Index child sex AOR 2⋅103; 95 % CI (1⋅015, 4⋅358) and health facility delivery AOR 3⋅033; 95 % CI (1⋅293, 7⋅117). The colostrum avoidance in the present study was 19 %. The study recommends the promotion of institutional delivery, timely initiation of breast-feeding, the shared household decisions about child feeding, avoiding sex preferences and stopping pre-lacteal feeding were critically important.

Mutual Pan-African support paradigm to produce scientific evidence of traditional medical practices for use against COVID-19 and emerging pandemics.

Africa is endowed with a profoundly rich and diverse system of plants and other bio-resources out of which, by traditional medicine practice, the people have satisfied their healthcare needs right from antiquity. In contemporary times, it has become necessary to modernize this traditional medical care system via scientific studies. Validation of the efficacy of health-enhancement products and drugs from plants and other bio-resources is predicated on diligent and intensive research accompanied by rigorous and conclusive clinical trials. Africa has eminently qualified human resources but due to the finance-intensive nature of medical research, individual African states on their own cannot fund the level of research desired for dealing with such serious issues as the COVID-19 pandemic. A collaboration among African states guided by a Mutual Pan-African support paradigm (MPASP) is a unique strategy for achieving success in any such a high-impact global project as the use of traditional medicine against COVID-19 and emerging pandemics; and this is hereby advocated.

HIV-related perceived stigma and associated factors among patients with HIV, Dilla, Ethiopia: A cross-sectional study.

INTRODUCTION: Understanding HIV-related perceived stigma has importance in improving the quality of patients and provides a better tackling of HIV stigma. Therefore; the study aimed to assess the prevalence and associated factors of perceived stigma among Patients with HIV attending the clinic at Dilla University Referral Hospital in Ethiopia 2019. METHOD: In this Institution based cross-sectional study, a 10-item perceived HIV stigma scale was used to assess HIV-related perceived stigma. Oslo social support scale was used to assess social support related factors. Bivariate and multivariate binary logistic analysis was done to identify associated factors to HIV-related perceived stigma. RESULTS: The prevalence of HIV-related perceived stigma by using perceived HIV stigma scale among patients with living HIV was 42.7%. Patients who are age groups 25-30 years (AOR = 2.8, 95% CI: 5.72-11.5), age groups 31-39 years (AOR = 1.11, 95% CI: 1.26,4.65), Females (AOR = 2.4, 95% CI: 1.28-4.33), divorced marital status (AOR = 8.9, 95% CI: 3.52-10.61), widowed marital status (AOR = 3.0, 95% CI: 2.74-7.60), Primary educational status (AOR = 7.5,95% CI: 3.45-9.74) and Study participants those who use alcohol (AOR = 1.0 95% CI: 1.57-2.11) were more likely to have HIV-related perceived stigma. CONCLUSION: This calls a holistic approach to the prevention and intervention of HIV-related perceived stigma. Emphasis should also be given for HIV-related perceived stigma. REGISTRATION: This study was registered research registry with the registration number (researchregistry7112).

Methodologies to measure the coverage of vitamin A supplementation: a systematic review.

Countries are increasingly transitioning from event-based vitamin A supplementation (VAS) distribution to delivery through routine health system contacts, shifting also to administrative, electronic-based monitoring tools, a process that brings certain limitations affecting the quality of administrative VAS coverage. At present, there is no standardised methodology for measuring the coverage of VAS delivered through routine health services. To address this gap, we conducted a systematic review of the literature to identify and recommend methods to measure VAS coverage, with the aim of providing guidance to countries on the collection of consistent data for planning, monitoring and evaluating VAS programmes integrated into routine health systems. We searched the PubMed®, Embase®, Scopus, Google Scholar and World Health Organization (WHO) Global Index Medicus databases for studies published from 1 January 2000 to 1 January 2021, reporting original data on VAS coverage and methodologies used for measurement. We screened 2371 original titles and abstracts, assessed twenty-seven full-text articles and ultimately included eighteen studies. All but two studies used a coverage cluster survey (CCS) design to measure VAS coverage, adapting the WHO Vaccination Coverage Cluster Surveys methodology, by modifying sample size and sampling parameters. Annual two-dose VAS coverage was reported from only four studies. Until electronic-based systems to collect and analyse VAS data are equipped to measure routine two-dose VAS coverage using administrative data, CCSs that comply with the 2018 WHO Vaccination Coverage Cluster Surveys Reference Manual represent the gold-standard method for effective VAS programme monitoring.

Cinnamomum zeylanicum Blume (Ceylon cinnamon) bark extract attenuates doxorubicin induced cardiotoxicity in Wistar rats.

Anti-tumour efficacy of doxorubicin is hindered by the cumulative dose-dependent cardiotoxicity induced by reactive oxygen species during its metabolism. As Cinnamomum zeylanicum has proven antioxidant potential, objective of this study was to investigate the cardioprotective activity of Cinnamomum bark extract against doxorubicin induced cardiotoxicity in Wistar rats. Physicochemical and phytochemical analysis was carried out and dose response effect and the cardioprotective activity of Cinnamomum were determined in vivo. 180 mg/kg dexrazoxane was used as the positive control. Plant extracts were free of heavy metals and toxic phytoconstituents. In vivo study carried out in Wistar rats revealed a significant increase (p < 0.05) in cardiac troponin I, NT-pro brain natriuretic peptide, AST and LDH concentrations in the doxorubicin control group (18 mg/kg) compared to the normal control. Rats pre-treated with the optimum dosage of Cinnmamomum (2.0 g/kg) showed a significant reduction (p < 0.05) in all above parameters compared to the doxorubicin control. A significant reduction was observed in the total antioxidant capacity, reduced glutathione, glutathione peroxidase, glutathione reductase, superoxide dismutase and catalase activity while the lipid peroxidation and myeloperoxidase activity were significantly increased in the doxorubicin control group compared to the normal control (p < 0.05). Pre-treatment with Cinnamomum bark showed a significant decrease in lipid peroxidation, myeloperoxidase activity and significant increase in rest of the parameters compared to the doxorubicin control (p < 0.05). Histopathological analysis revealed a preserved appearance of the myocardium and lesser degree of cellular changes of necrosis in rats pre-treated with Cinnamomum extract. In conclusion, Cinnamomum bark extract has the potential to significantly reduce doxorubicin induced oxidative stress and inflammation in Wistar rats.

Indoors ventilation in times of confinement by SARS-CoV-2 epidemic: A comparative approach between Spain and Italy.

With the arrival of the SARS-CoV-2 coronavirus, the scientific academia, as well as policymakers, are striving to conceive solutions as an attempt to contain the spreading of contagion. Among the adopted measures, severe lockdown restrictions were issued to avoid the diffusion of the virus in an uncontrolled way through public spaces. It can be deduced from recent literature that the primary route of transmission is via aerosols, produced mainly in poorly ventilated interior areas where infected people spend a lot of time with other people. Concerning contagion rates, accumulated incidence or number of hospitalizations due to COVID-19, Spain, and Italy have reached very high levels. In this framework, a regression analysis to assess the feasibility of the indoor ventilation measures established in Spain and Italy, with respect to the European framework, is here presented. To this aim, ten cases of housing typology were and analyzed. The results show that the measures established in the applicable regulations to prevent and control the risk of contagion by aerosols are not adequate to guarantee a healthy environment indoors. The current Italian guidelines are more restrictive than in Spain, yet the ventilation levels are still insufficient in times of pandemic.

Natural medicinal plant products as an immune-boosters: A possible role to lessen the impact of Covid-19.

Transmissible Covid-19, caused by novel corona virus since last of 2019 has outspread widely until now. Where, India was the second most affected country and 3rd in mortality rate. In world ancient history, medicinal plants were played a crucial role to cure several diseases. In present study, we show some novel natural medicinal plant metabolites as the potential inhibitors against papain-like protease (PLpro), main protease (Mpro) and RNA-dependent RNA polymerase (RdRp), transmembrane proteinase Serine 2 (TMPRSS2) and angiotensin converting enzyme-2 (ACE-2) of Covid-19. Plant metabolites were having been proven to inhibit SARS-CoVs, which also actively walkable against Covid-19.

Complete diaphysis resorption of the femur: A case report in a metastatic papillary thyroid cancer.

INTRODUCTION: Although differentiated thyroid cancers generally have a good prognosis, a small proportion of patients will have recurrent or progressive disease. Bone resorption due to thyroid cancer can cause significant challenges in the clinical management and rehabilitation. PRESENTED CASE: Nearly total femur resorption was found as a first presentation in a patient with thyroid cancer. The patient complained about chronic pain in her left thigh that had progressed into an inability to walk. She was treated by a traditional healer for six years before she was persuaded by a social worker to seek medical help. X-rays showed pathological loss of the right diaphyseal femur. Neck CT-scan showed a left thyroid mass with tracheal deviation, with multiple lytic lesions in the sternum and 5th rib. Needle biopsy of the thyroid mass resulted in an inconclusive follicular neoplasm. Total thyroidectomy and neck dissection revealed a classical type of papillary thyroid carcinoma. After thyroid ablation, she opted for palliative radiotherapy and bisphosphonate treatment for the bone metastases. DISCUSSION: Bone metastases are rarely detected at the time of thyroid cancer diagnosis. In the presence of bone metastasis, median survival of well-differentiated thyroid cancer decreases into only 4 years. Bone metastases are often neglected and less studied than regional lymph node and lung metastases. CONCLUSION: Although well differentiated thyroid cancer is usually indolent, a neglected bone metastasis at an initial diagnosis might adversely affect patient's quality of life and prognosis.

Prescribing laughter to ameliorate mental health, sleep, and wellbeing in university students: A protocol for a feasibility study of a randomised controlled trial.

OBJECTIVES: This research is the first study to investigate the potential effects of a laughter prescription on both psychological health and objective sleep parameters in university students. The primary objective is to evaluate the feasibility of prescribing laughter to inform a larger randomised controlled trial. Secondary objectives are to assess if a two-week laughter prescription improves subjective and objective sleep outcomes, wellbeing, and/or psychological health outcomes. TRIAL DESIGN: To assess the feasibility of a randomised controlled trial for laughter prescription in relation to sleep, psychological health, and wellbeing. Forty university students will be recruited and randomised to one of two conditions (control/experimental). METHODS: Wrist actigraphy and sleep diaries will be used to estimate sleep outcomes during a one-week baseline testing phase and across the two-week intervention. The experimental group will be shown how to record a Laughie (a 1-min recording of their joyful laughter on their smartphone) and prescribed to laugh with it three times daily for 14 days (the control group will only track sleep). All participants will complete the WHO (Five) Well-being Index, and Hospital Anxiety and Depression Scale pre- and post-intervention. The CONSORT checklist, and the Feasibility, Reach-out, Acceptability, Maintenance, Efficacy, Implementation, and Tailorabilty (FRAME-IT) framework will guide intervention planning and evaluation. Participant interviews will be analysed using Differential Qualitative Analysis (DQA). RESULTS: The feasibility of a two-week laughter prescription in university students and its impact on sleep, wellbeing, and/or psychological health outcomes will be assessed. CONCLUSIONS: Zayed University Research Ethics Committee approved the study in July 2019. The research will be completed following protocol publication. TRIAL REGISTRATION: ClinicalTrials.gov. ID: NCT04171245. Date of registration: 18 October 2019.

Phytochemicals containing biologically active polyphenols as an effective agent against Covid-19-inducing coronavirus.

The outbreak of Covid-19 disease caused by SARS-CoV-19, along with the lack of targeted medicaments and vaccines, forced the scientific world to search for new antiviral formulations. In this review, we describe the current knowledge about plant extracts containing polyphenols that inhibit Covid-19. Many plant-derived natural compounds (polyphenols) might provide a starting point for the research on the use of plant extracts in coronavirus treatment and prevention. Antivirus polyphenolic drugs can inhibit coronavirus enzymes, which are essential for virus replication and infection. This group of natural substances (betulinic acid, indigo, aloeemodine, luteolin, and quinomethyl triterpenoids, quercitin or gallates) is a potential key to designing antiviral therapies for inhibiting viral proteases. The known pharmacophore structures of bioactive substances can be useful in the elaboration of new anti-Covid-19 formulations. The benefit of using preparations containing phytochemicals is their high safety for patients and no side effects.

Bioactive natural compounds against human coronaviruses: a review and perspective.

Coronaviruses (CoVs), a family of enveloped positive-sense RNA viruses, are characterized by club-like spikes that project from their surface, unusually large RNA genome, and unique replication capability. CoVs are known to cause various potentially lethal human respiratory infectious diseases, such as severe acute respiratory syndrome (SARS), Middle East respiratory syndrome (MERS), and the very recent coronavirus disease 2019 (COVID-19) outbreak. Unfortunately, neither drug nor vaccine has yet been approved to date to prevent and treat these diseases caused by CoVs. Therefore, effective prevention and treatment medications against human coronavirus are in urgent need. In the past decades, many natural compounds have been reported to possess multiple biological activities, including antiviral properties. In this article, we provided a comprehensive review on the natural compounds that interfere with the life cycles of SARS and MERS, and discussed their potential use for the treatment of COVID-19.

Safety and therapeutic effects of anti-fibrotic Traditional Chinese Medicine Fuzheng Huayu on persistent advanced stage fibrosis following 2 years entecavir treatment: Study protocol for a single arm clinical objective performance criteria trial.

BACKGROUND: Hepatitis B virus (HBV) infection is an important etiology for chronic hepatitis globally, and especially so in China. HBV infection can lead to the development of cirrhosis through the pathological process of liver fibrosis. The effective suppression of HBV replication with NAs or interferon-alpha can histologically regress the fibrotic pathological process, but there remain patients who have achieved anti-viral responses and normalization of serum liver tests, but not liver fibrosis regression. This subset of patients typically presents with advanced liver fibrosis at baseline. Therefore, it is reasonable to administer the anti-fibrotic agents, coupled with antivirals for patients with advanced liver fibrosis due to HBV, in order to improve the fibrotic regression of the patients. Fuzheng Huayu (FZHY) tablet is a botanical product with evidence demonstrating its efficacy against mild to moderate liver fibrosis. The current clinical trial evaluates the efficacy and safety of the combination therapy of traditional Chinese medicine (TCM) (FZHY and herbal granule) and entecavir for HBV compensated cirrhosis. We will enroll HBV patients who presented with a good viral response after 2 years of entecavir treatment but had advanced liver fibrosis (≥Ishak F5). METHODS: This is a single-arm clinical trial, conducted in 20 centers in mainland China over a period of 60 weeks, including 48 weeks of treatment observation and 12 weeks of follow-up. The main inclusion criteria include HBsAg positive more than 6 months, 2 years administration of entecavir, HBV DNA less than 20 IU/ml, liver fibrotic stage ≥ F5, and Child-Pugh scoring <7 (Stage A). The sample size is estimated to be about 190, considering a 20% drop-out and 60% of patient's compliance for the second liver biopsy so a total of 350 participants will be enrolled. All eligible participants are divided into 3 subgroups according to the TCM clinic pattern. And all patients will take 1 Entecavir tablet (0.5 mg) per day, 4 FZHY tablets (1.6 g) three times a day, and specific TCM granule three times a day, which is decided by TCM clinical patterns (CPs) differentiation. The patients were treated for 48 weeks, and follow-up visits at 12, 24, 36, 48 weeks and 60 weeks. The patients will receive the second liver biopsy at the end of 48 weeks, with a 12 weeks follow-up after that.The primary endpoint is the proportion of subjects with a 1-point improvement of liver fibrosis stage using the Ishak score from baseline to week 48 in the study, according to consensus readings evaluated by a panel of hepato-pathologists. The secondary endpoints are the brightness-mode ultrasonic, fibrotic biomarkers. The adverse events (AEs) will be recorded for 60 weeks, and the safety of the combination therapy will be evaluated. Meanwhile, the efficacy in the 3 sub-groups will be stratified and analyzed. DISCUSSION: The study has been designed to test the therapeutic effects and safety of the combination therapy of FZHY and herbal granule with entecavir on persistent advanced stage fibrosis/cirrhosis following 2 years entecavir treatment, and to explore an effective integrative therapy on HBV cirrhosis. TRIAL REGISTRATION: ClinicalTrials.gov. NCT02241616. Registered on September 16, 2014.

A pilot randomised trial comparing a mindfulness-based stress reduction course, a locally-developed stress reduction intervention and a waiting list control group in a real-life municipal health care setting.

BACKGROUND: The purpose of the present study was to conduct a pilot randomised controlled trial (RCT) to lend support to a larger effectiveness RCT comparing Mindfulness-Based Stress Reduction (MBSR), a locally-developed stress reduction intervention (LSR) and a waiting list control group in a Danish municipal health care center setting. METHODS: A three-armed parallel pilot RCT was conducted among 71 adults who contacted a Danish municipal health care center due to stress-related problems. Recruitment was made between January and April 2018 and followed usual procedures. EXCLUSION CRITERIA: 1) acute treatment-demanding clinical depression or diagnosis of psychosis or schizophrenia, 2) abuse of alcohol, drugs, medicine, 3) pregnancy. Randomisation was performed by an independent data manager using the REDCap electronic data capture tool. The primary outcome was a description of RCT feasibility (recruitment and retention rates regarding intervention participation and 12-week follow-up). Secondary outcomes were completion rates regarding questionnaire data and proposed effect-estimates of outcome measures considered to be used in the following real RCT. Type of intervention and outcome assessment were not blinded. RESULTS: We recruited 71 of 129 eligible individuals from the target population (55, 95%CI: 46-64). Forty-two (59%) were females. Median age: 44 years (1-quartile:34, 3-quartile:50). Twenty-nine (41%) had < 16 years of education. Forty-eight (68%) were employed; 30 of these 48 (63%) were on sick leave. Mean scores for perceived stress (PSS): 25.4 ± 5.3; symptoms of anxiety and depression (SCL-5): 2.9 ± 0.6, and well-being (WHO-5): 31.7 ± 8.5 indicated a need for intervention. 16/24 (67, 95%CI: 45 to 84) who were allocated to MBSR and 17/23 (74, 95%CI: 52 to 90) who were allocated to LSR participated in ≥5 sessions. The loss to follow-up at 12 weeks: MBSR: 5 (21% (95% CI: 7 to 42), LSR: 5 (22% (95% CI: 7 to 44) and waiting list: 4 (17% (95% CI: 5 to 37). This was acceptable and evenly distributed. The results indicated MBSR to be superior.
