Published: October 2020

Objective: Heart rate variability has been proposed as a valid method to examine the individual response to training load in endurance athletes. Thanks to this tool, the relationship between basal and post-exercise Heart rate variability measurements can be analyzed during a microcycle (one week) using straight values or their coefficients of variation.
Method: Ten amateur endurance athletes (n = 5 men, n = 5 women) were monitored during a 7-day microcycle that included three road-cycling sessions, two running sessions and two trail-running sessions. The RR series were measured for 5 minutes upon wake up and after training, in a seating position, using a chest strap.
Results: Basal and post-exercise Heart rate variability measurements showed high correlation when weekly mean values were used, very similar to when coefficients of variation values were used. In women, the root mean square of successive differences (RMSSD) was: r= 0.73; RMSSD coefficients of variation (RMSSDcv) was: r= 0.66; natural logarithm (Ln) RMSSD: r= 0.68; LnRMSSDcv: r= 0.79; and in men it RMSSD was: r= 0.78; RMSSDcv: r= -0.62; LnRMSSD: r= 0.75; LnRMSSDcv: r= -0.73).
Conclusion: the relationship between these two measurements could be useful to program the training loads of the following microcycle.

Published: October 2020

Bangladesh is a developing country with a very high prevalence of antibiotic resistance where irrational use of antibiotics is very common. This cross-sectional survey was conducted to assess the knowledge of antibiotics and antibiotic usage behavior (Antibiotic use, self-medication, adherence to therapy) among the people of Bangladesh. The association between participants’ knowledge of antibiotics and their antibiotic usage behavior was also analyzed. A cross-sectional survey based on a structured questionnaire was conducted in the Dhaka district. The questionnaire included questions about demographic information, participants’ knowledge of antibiotics, and their recent antibiotic usage. The data analysis involved the use of descriptive statistics and multivariable logistic regression. Very few participants knew that antibiotics are not effective against most common colds (16.8%), viruses (22.5%), and pains (41.7%). Most respondents (>75%) knew that excessive use of antibiotics and failing to complete a course may render antibiotics less effective in the future. However, only 56.1% were aware of antibiotic resistance. About half (46.6%) of the participants took antibiotics in the last six months, 20.5% of whom resorted to self-medication and 23.1% reported non-adherence to therapy. Greater knowledge of antibiotics was significantly associated with lower rates of self-medication (p=0.037). Misconceptions about antibiotics and antibiotic misuse are very common in Bangladesh. The findings suggest that misconceptions about antibiotics and antibiotic misuse are very common in Bangladesh. To mitigate these problems, interventions comprised of educational campaigns and redesigning of the healthcare system and policies should be undertaken.

Biodegradable plastics adalah plastik yang memiliki sifat ramah lingkungan. Kulit pisang candi berpotensi digunakan sebagai bahan dasar pembuatan bioplastik karena mengandung pati sebesar 28,488 %. Penelitian ini bertujuan untuk mengetahui pengaruh plasticizer (sorbitol) dan filler (kalsium silikat dan clay) terhadap kuat tarik, % elongasi, % biodegradasi dan % absorpsi bioplastik. Berdasarkan hasil yang diperoleh, semakin banyak filler clay atau kalsium silikat maka bioplastik memiliki kuat tarik yang besar dan % elongasi yang semakin kecil. Semakin banyak clay yang ditambahkan maka semakin besar daya absorpsi terhadap air, namun semakin banyak kalsium silikat yang ditambahkan maka semakin kecil daya absorpsi terhadap air. Semakin banyak filler kalsium silikat dan clay maka semakin kecil % biodegradasi bioplastik. Semakin banyak jumlah sorbitol yang ditambahkan maka semakin besar % elongasi, % biodegradasi dan % water absorption namun semakin kecil % kuat tarik. Bioplastik dengan penambahan filler kalsium silikat memiliki kuat tarik antara 4,11-22,08 Mpa, % elongasi antara 2,17%-57,95%, % water absorption antara 67,26%-120% dan %biodegradasi antara 0,61%-19,22%. Bioplastik dengan penambahan filler clay memiliki kuat tarik antara 2,38-14,05 Mpa, %elongasi antara 2,11%-46,24%, % water absorption antara 79,07%-150,67% dan %biodegradasi antara 1,17%-34,54%.
