Published: November 2022

Smoking is a habit that is favored by some people, but smoking causes health, economic, social and environmental burdens not only for smokers but also for others. This study aims to determine the mathematical model of the number of smokers, analysis of the equilibrium point of the PLSQ mathematical model of the number of smokers and a simulation of the mathematical model of the PLSQ of the number of smokers. In this study, the researcher assumed that the current smoker had a death rate caused by smoking and that the former smoker after he recovered, would not return to smoking. The results obtained are the PLSQ mathematical model of the number of smokers which produces 1 (one) smoke-free equilibrium point and 1 (one) smoker endemic point from the model. The stability analysis of the model was carried out using the Routh-Hurwitz Criteria to identify the characteristics of the eigenvalues. From the results of the stability analysis, it was found that the smoker-free equilibrium point E0 and the smokers endemic equilibrium point E1 were stable if the condition for the relationship between parameters were met. At the end of the study, a simulation model was given using the Maple application

<p>Objection: The objective of this study was to assess attitudes towards the use of Traditional Chinese Medicine (TCM) for COVID-19 among Chinese immigrants in Canada during the early stage of the COVID-19 pandemic. </p>
<p><strong>Methods</strong>: A cross-sectional study was conducted in April 2020 in Canada. Individuals aged 16 or older who were of Chinese origin and living in Canada at the time of the survey were invited to participate in an online survey. Descriptive and univariate statistics were performed to describe participant attitudes towards various preventive and treatment measures for COVID-19. Multiple logistic regression was used to identify independent associations with sociodemographic factors and attitudes. </p>
<p><strong>Results: </strong>A total of 754 eligible respondents were included in the analysis. 65.8% of the participants were female, 77.2% had a university degree or higher and 28.6% were 55 years of age or older. Overall, 48.8% of the study participants believed that TCM was effective in preventing COVID-19% and 46.2% would use TCM if they had COVID-19-related symptoms. However, the corresponding numbers for western medicine were 20.8% and 39.9%, which were statistically lower (p<0.01). Older participants (55+vs <35, OR=3.55 (95% CI 2.05 to 6.14); 35–54 vs <35, OR=1.98 (95% CI 1.27 to 3.08)) and those who were dissatisfied with their income (OR=2.47(95% CI 1.56 to 3.92)) were more likely to believe TCM was effective against COVID-19. Similarly, older participants (55+vs <35, OR=3.13 (95% CI 1.79 to 5.46); 35–54 vs <35, OR=2.25 (95% CI 1.35 to 3.74)), females (OR=1.60 (95% CI 1.15 to 2.23)), and those born in mainland China (OR=10.49 (95% CI 2.32 to 47.39)) were more likely to use TCM if they had symptoms of COVID-19. </p>
<p><strong>Conclusion</strong>: Despite the lack of scientific evidence to support its use, TCM was widely believed by Chinese immigrants in Canada to be an effective means of preventing COVID-19 and many also stated they would use it if they were experiencing symptoms of COVID-19. </p>

Authors: Wilkinson Andrea J. , Yang Lixia 
Published: November 2022

<p>Objectives: The aim of this study is to examine the long-term maintenance of training benefits in inhibition, as measured with the Stroop task, in older adults over 1- and 3-year periods. Methods: Participants from an original 6-session Stroop training study (Wilkinson & Yang, 2012 [Wilkinson, A. J., & Yang, L. (2012). Plasticity of inhibition in older adults: Retest practice and transfer effects. Psychology and Aging, 27, 606–615. doi:10.1037/a0025926]) were invited to come back to the lab to complete a single session of the Stroop task at 2 different time points. Thirty-three older adults returned for the 1-year follow-up session, and 26 of them returned for the 3-year follow-up session. Results: The results revealed maintenance of the training-induced inhibition gains at both follow-up sessions. Furthermore, performance at the 2 follow-up sessions was better (i.e., reduced Stroop ratio interference score) than baseline level. Discussion: The findings demonstrate the durability of inhibition training gains in older adults for up to a 3-year period. These results further extend the literature on long-term maintenance of cognitive training benefits in older adults by examining the durability of training effects in inhibition, an important executive function, and by covering a substantial maintenance period (i.e., up to 3 years). </p>

Authors: Hossain Md Iqbal , Akter Nasima , Rahman Abdur 
Published: November 2022

Telemedicine has the potential to help facilitate the delivery of health services to rural and remote areas. In somecircumstances, telemedicine may also be useful for the delivery of education and teaching programmes and the facilitation of administrative meetings. In this paper reference is made to a variety of telemedicine applications. An overriding imperative is to focus on the clinical problem first with careful consideration given to the significant organisational changes which are associated with the introduction of a new or alternative method of health service delivery for remote patients. For telemedicine to be effective it is also important that all sites involved are adequately resourced in terms of staff, equipment, telecommunications, technical support and training. In addition, there are a number of logistical factors which are important when considering the development of a telemedicine service including site selection, clinician empowerment, telemedicine management, technological requirements, user training, telemedicine evaluation, and information sharing through publication.

Treatment with antiviral drugs improve survival and quality of life by preventing disease progression and Hepatocellular Carcinoma (HCC). Indications for antiviral treatment primarily based on serum HBV DNA, Alanine Aminotransaminase (ALT) and severity of liver disease. Entecavir is one of the potent antiviral drug against hepatitis B virus. This study has been conducted to evaluate the efficacy of entecavir in both Hepatitis Be Antigen (HBeAg) positive and HBeAg negative treatment naïve Bangladeshi patients. Materials and methods: A total 205 patients were enrolled in this study from 2010-2014 in outpatients department of Hepatology in Chattogram Medical College Hospital. All patients got Entecavir 0.5 mg daily and followed at 12 weeks, 24 weeks & 52 weeks of the treatment by ALT, HBsAg, HBe- Ag and HBV DNA. 55 patients lost during follow- up and 150 patients completed 52 weeks treatment and finally evaluated. Results: The mean HBV DNA at baseline was 26.4 x 109 ± 7.4 x 109 copies / ml which was decreased to 2.2 x 106 ± 1.4 x 105 copies/ml at the end of 52 weeks which was statistically significant. At 52 weeks 118 (78%) CHB patient became HBV DNA negative. The mean ALT level before treatment were 96.1 ± 70.9 U/L which were 39.7 ± 11.98 U/L at the end of 52 weeks. At 52 weeks of treatment 78 (71.5%) became HBeAg negative. Conclusion: Entecavir significantly suppress HBV DNA level as well as normalization of aminotransfersae level. It has significant influences on HBeAg negativity in HBeAg positive chronic hepatitis B patients.

Published: November 2022

In conservation areas throughout Indonesia, there are at least 1.8 million hectares of open land in the form of damaged or degraded ecosystems following encroachment on conservation areas by local communities. Addressing this, the government of Indonesia has introduced a conservation partnership policy issued in 2018, namely the Director General of KSDAE Regulation No. P.6/KSDAE/SET/Kum.1/6/2018 concerning Technical Guidelines for Conservation Partnerships in Nature Reserves and Nature Conservation Areas. The objective of this study was to identify and analyze the impact of conservation partnerships on improving the welfare of the community in the Gunung Masigit Kareumbi Hunting Park (GMKHP). The research was conducted within the GMKHP area, with the samples taken from the community of Forest Farmer Groups (KTH) in the villages of Pelita Asih, Jaya Mekar, Sunda Mekar, Cikadu, Sukajaya, and Kaduwulung. The approach used in this study is qualitative. Data were collected by questionnaire survey, interviews, observations, and documentation in the field. Based on the results of the study, it is known that the production of pine resin tapping carried out by KTH members is as much as 29,033 kg/month or an average of 323 kg/person per month. This activity has an impact on increasing the income of KTH members by 170%, i.e. from their initial average income of Rp. 853,778 per month to become Rp. 2,307,278/month for each member. Additionally, there are also contributing funds to the neighborhood and social welfare coordinated by cooperatives, such as assistance for the poor and orphans, village treasury income, BUMDes (Village Enterprise) capital, wages for reading Qoran teachers, mosque maintenance, etc.
