Eighteen cardiorespiratory parameters were measured in a five-minute bicycle ergometer test applied before and after four hours of resting (control days) or four hours of treadmill walking at 40, 50, and 60% of the maximum aerobic capacity (exercise days) of four volunteer subjects. There was no significant difference between control and exercise days in 16 out of 18 responses when the mean differences between the results obtained in the “before” and “after” tests were compared. The two exceptions were resting and exercise heart rate at 50 and 60% of the maximum aerobic capacity. Consequently, nine parameters showing the largest changes on exercise days were selected for calculation of a cardiorespiratory variance score (CVS). Subjective feeling of fatigue quantitated by the feeling tone checklist of Pearson was significantly correlated with CVS. There was also a significant relationship between work strain and the CVS. These results suggests that the physiological manifestations of fatigue after strenuous work are not reflected in consistent changes of single parameters but rather in the composit deviation of several responses from the control level. Within equal CVS values, deviation of single parameters may vary day by day in the same individual at identical work loads indicative of instability of homeostatic control during fatigue.

The present investigation evaluated the efficacy of a botanical supplement that delivered a concentrated dose of Echinacea purpurea (8 grams day−1). The participants were 13 apparently healthy, recreationally active college students (VO2 max: 51 mL O2/kg*min). The participants were provided with a 30-day supplementation regime. Data regarding maximum aerobic capacity was collected through pre- and posttesting surrounding the 30-day supplementation regime. The participants were instructed to maintain normal levels of physical activity and exercise during the experimental period. The levels of physical activity and exercise were monitored via the Leisure and Physical Activity Survey. The participants did not report any significant increases in aerobic physical activity or exercise during the supplementation period. Paired samples t-test analysis did not reveal a significant difference in maximum aerobic capacity, t12=0.67, P=.516. Presupplementation maximum aerobic capacity (M=51.0, SD=6.8) was similar to postsupplementation values (M=51.8, SD=6.5). This study suggests that botanical supplements containing a concentrated dose of Echinacea purpurea is not an effective intervention to increase aerobic capacity of recreationally active individuals.

This study was intended to investigate the effect of aerobic gymnastic training at the menstrual cycle phase and perceptions of female students of Sport Science Faculty of State University of Padang on maximum aerobic capacity. The research was conducted using repeated factorial design 2 x 3. Aerobic gymnastic training was a treatment given to the menstrual cycle phase as independent variables, perception as the attribute variable, and the maximum aerobic capacity as the dependent variable. 40 students were taken by using purposive sampling technique as the samples from 170 female students enrolled at 2010/2011 academic year. The data of menstrual cycle phase and perception were collected by using questionnaires while the data of maximum aerobic capacity were taken by using MSFT (beep test). The data of maximum aerobic capacity were then analyzed using by inferential statistics ANOVA 2 x 3 two paths .The data analysis and interpretation indicate that: (1) as the whole, there is a significant difference of the effect of aerobic gymnastic training during premenstrual, menstrual, and postmenstrual phases on the maximum aerobic capacity; (2) there is an interaction between the effects of aerobic gymnastic training during the menstrual phases and the perception on maximum aerobic capacity; (3) there is no significant effect of aerobic gymnastic training during premenstrual and menstrual phases of the students whose positive perception on maximum aerobic capacity; (4) there is a significant effect of aerobic gymnastic training during premenstrual and postmenstrual phases of the female students whose positive perception on maximum aerobic capacity; (5) there is no significant effect of aerobic gymnastic training during menstrual and postmenstrual phases of the female students whose positive perception on maximum aerobic capacity; (6) there is a significant effect of aerobic gymnastic training during premenstrual and menstrual phases of the female students whose negative perception on maximum aerobic capacity; (7) there is no significant effect of aerobic gymnastic training during premenstrual and postmenstrual phases of the female students whose positive perception on maximum aerobic capacity; and (8) there is a significant effect of aerobic gymnastic training during menstrual and postmenstrual phases of the female students whose negative perception on maximum aerobic capacity. The findings imply that the lowness of maximum aerobic capacity of the students during menstruation is not mainly due to the menstruation itself but more to the negative perception during on the maximum aerobic capacity. Therefore, the teachers, lecturers, and trainers are expected to provide the female students (at any levels of education) with better explanation on the menstrual cycle phases and their effects on physical activities (sports)

This study is aimed to compare the blood cholesterol profile, before and after the measurement of maximum aerobic capacity (VO2max) in the students of Jurusan Pendidikan Olahraga dan Kesehatan (JPOK) pada Fakultas Keguruan dan Ilmu Pendidikan (FKIP) Universitas Lambung Mangkurat Banjarmasin.Variables in this study consist of lipid profiles, including total cholesterol, high density lipoprotein (HDL), low density lipoprotein (LDL), triglyceride (TG) and Maximum Aerobic Capacity (VO2max). The concept of VO2max according to Kent(1994:268): “maximum oxygen volume consumed per minute to show total work capacity, or volume per minute relative to body weight (ml/kg.min)”. Operationally, VO2max referred in this study is the maximum volume of oxygen that can be consumed per minute, as measured at progressive run (Bleep Test).<br />The method used in this study is pre-experimental with one group pretest-posttest design. This design implies that a group of subjects are treated for a specific period and the measurements are taken both pre and post. The results: There are changes in blood cholesterol profile after the measurement of maximum oxygen capacity (VO2max), shown by significant decrease of total cholesterol variable, increased HDL, and decreased LDL. Changes in triglyceridevariable showed no significant decrease despite the statistic differences. Specific HDL sub-class increasing after exercise is a constructive lipoprotein sub-class whereas LDL is destructive lipoproteins sub-class that might damage the body. Therefore, an increase in HDL and decrease in LDL found in this study appears to be advantageous and consequently might alter the risk of coronary heart disease.

Background Recurrent abdominal pain (RAP) is one of the mostcommon complaints in adolescents. Treatment for RAP dependson the etiology. Lansoprazole has been shown to be effective ongastroesophageal reflux disease (GERD), but further study isneeded to assess the effects of lansoprazole on RAP.Objective To assess quality of life (QoL) of RAP patients whoreceived lansoprazole compared to placebo treatment.Methods This randomized, clinical trial was conducted in theSecanggang District, Lan gkat Regency, North Sumatera, fromAugust to October 2009. Patients who met the Apley criteria forRAP diagnosis were enrolled in the study. Subj ects were dividedinto two groups: those who received 30 mg lansoprazole daily andthose who received placebo, for 14 days. Quality oflife was assessedusing the Pediatrics Quality of Life (PedsQL) version 4.0 beforeadministration oflansoprazole/placebo and reassessed 30 days aftertreatment. Efficacy of treatment was assessed by comparing theQoL before and after treatment in the two groups.Results A total of 98 adolescents, aged 12 - 18 years, wereenrolled in the study and divided into two groups: lansoprazoleand placebo. There was no significant difference QoL in physicalhealth (mean differences 95%CI -109.19 to 1.02; P=0.054),emotional health (mean differences 95%CI -29.26 to 45.48;P=0.666), social functioning (mean differences 95%CI -42.91to 31.69; P=0.766), and sch ool functioning (mean differences95%CI -56.97 to 24.32; P= 0.430), before and after treatmentin the two groups.Conclusion There is no significant difference in QoL between thetwo groups of adolescents with RAP before and after lansoprazoletreatment.

Abstract Background: Recruitment to psychiatry has been challenging in Canada and abroad. Historically 4-6% of medical students match to psychiatry in Canada. Novel and innovative measures to increase interest in psychiatry among medical students are needed to meet the increasing demand for psychiatrists given the increasing burden of mental health issues globally. Common barriers include negative attitudes and stigma towards psychiatry and a paucity of knowledge about the field. The study goal was to evaluate the efficacy of the Ottawa Psychiatry Enrichment Program (OPEP), a one-week extracurricular program about psychiatry as a career, developed for 1st and 2nd year medical students to improve medical students’ attitudes towards psychiatry, and increase recruitment.Methods: 1st and 2nd year medical students from Canada applied to OPEP. Attendees completed the Attitudes Towards Psychiatry Questionnaire (ATP-30) before OPEP (PreOPEP), after OPEP (PostOPEP) and after their Canadian Residency Matching Service (CaRMs) match 2-3 years later. OPEP ATP-30 scores were compared to third-year student ATP-30 scores before and after their psychiatry rotation. Data were analysed using Friedman non-parametric ANOVA and post hoc testing by either Wilcoxon rank sum test, Wilcoxon matched pairs signed rank test, or parametric Welch independent t-test as appropriate. Effect sizes of group mean differences were calculated using Cohen’s “d”. Results: 29 students were selected for OPEP from 2017-2018 from across Canada. 100%, 93.1% and 75.8% of students completed the PreOPEP, PostOPEP, and CaRMs ATP-30 surveys respectively. 43% of OPEP attendees matched to psychiatry. PostOPEP ATP-30 scores (mean=133, median=137, SD=10.6) were significantly higher than PreOPEP ATP-30 (mean score=121, median=122, SD=9.3, p < 0.001) and CaRMS ATP-30 (mean=126, median=127, SD=12.3, p < 0.02) scores. OPEP effect size on ATP-30 scores was large (d=1.2) but decreased 2-3 years later (p=0.078, d=0.44). 97/202 students completed the ATP-30 before and after their psychiatry rotation (clerkship). Clerkship effect size on improvement in ATP-30 was moderate (d=0.39). There was a non significant difference between OPEP CaRMS ATP-30 and post clerkship ATP-30 scores (median 127 vs 121, p=0.056). Conclusions: OPEP ameliorated attitudes toward Psychiatry, but improvement deteriorated longitudinally. Additional strategies to boost/retain these improvements during clerkship years may be beneficial.

The 3rd trimester of pregnancy is the time for one to prepare both physiologically and psychologically for baby birth and nursing. The pregnancy during this final trimester causes incovenience due to fetus and uterus enlargements. The pain during pregnancy and approaching the labor in pregnant mothers might increase their anxiety. One of attempts to reduce this anxiety resulting from pain in pregnant mothers employs nonpharmacologic method in the form of endorphin massage. This research was quasi experimental with one group pretest posttest design. It used analytical comparative research method since the researcher tried to study the existence of endorphin massage influence on anxiety in pregnant mothers. The results revealed that there was some mean differences before and after the therapy was given. The mean score before the therapy was given was 1.6 and after the therapy was given was 1.2. The difference between these two mean score was 0.4. From the analysis, it was found that the p-value was 0.037, meaning that there was a significant difference of anxiety level between before and after the provision of endorphin massage. Keywords: endorphin; pregnancy; anxiety

There is increasing evidence that patients who were infected with SARS-CoV-2 may experience adverse health outcomes months after the acute infection has resolved including reduction in aerobic capacity and fatigue. In this study, we compared aerobic capacity and exercise performance of 28 unvaccinated participants to 15 vaccinated ones who performed a symptom limited cardio-pulmonary exercise test (CPET) after acute COVID-19. We identified a significant difference in aerobic capacity between vaccinated and unvaccinated individuals, with a lower V'O2 peak percentage of predicted in the unvaccinated group. In addition, the unvaccinated group had a reduction in the peak-exercise heart rate and lower ventilation values. Our results suggest objective limitations to exercise capacity in the months following acute COVID19 illness, mitigated by vaccination

Algae (Ulva sp.) and tuna (Thunnini) are edible marine resources rich in protein, essential amino acids, zinc, and iodine that can be used to improve the growth of malnourished children including their cognitive functions. The combination of both resources may produce a supplementation (Furikake Ulvamina) with nutritional quality to support the acceleration of cognitive functions of malnourished children. This study aimed to develop a marine-based product/supplement to accelerate cognitive functions in malnourished mice (Rattus norvegicus). A product called “Furikake Ulvamina” was used in an experimental study of 25 malnourished mice. The Morris Water Maze test was adapted into a “speed time to survive” to test the cognitive functions of each group. One-way Anova tests were performed to statistically analyze the mean differences in the speed of time to survive before and after the intervention. All five groups showed an increase in the speed of time to survive after treatment was given with an average increase of speed of 26.9 seconds. Statistically, there was no significant difference in this cognitive function acceleration indicator between groups (p>0.05). Furthermore, weight and length were also increased after four weeks in all groups. There was no significant difference in cognitive function acceleration in each group of mice after the supplementation of Furikake Ulvamina for four weeks. This product may potentially accelerate growth in malnourished mice. Furikake Ulvamina can also promote the consumption and benefits of Indonesian marine local commodities (algae and tuna).

Introduction: Psychological issues are big barriers for female patients referring for colorectal examination. Some interventions might reduce these issues. This study aimed to determine the effect of an educational-pyschyological intervention on anxiety, bodily embarrassment, judgment concern, and comfort in female patients who referred to a male general surgeon for colorectal examination. Methods: This clinical trial with a pre/posttest design was conducted in Imam Hassan Mojtaba Clinic, Darab, Iran. Total of 110 female patients who referred to a male general surgeon for colorectal examination were included in this study. The participants were randomly assigned to an intervention (n=55) and control (n=55) groups. The psychological training program was conducted for 60 minutes (30 minutes for examinations and 30 minutes for the psychological counseling). Beck Anxiety Inventory and Medical Embarrassment Questionnaires were used. The data were analyzed using chi-square, independent and paired t-test. Results: After the intervention, a significant difference was observed between the intervention and control groups in terms of bodily embarrassment and comfort. In addition, a significant difference was found in the intervention group regarding the mean differences of anexity, bodily embarrassment, judgment concern, and comfort scores before and after the intervention (p<0.001). Conclusion: The findings showed that the educational-psychological intervention reduced anxiety, bodily embarrassment, and judgment concern, and it improved comfort in female patients who referred to the male general surgeon for colorectal examination. Hence, this intervention might be used in primary, secondary and tertiary health centers to educate patients when referring to a male surgeon.

Purpose: This study aimed to search for randomized clinical trials evaluating the clinical effectiveness of ertapenem compared to piperacillin/tazob actam in adult patients with mild to moderate intra-abdominal infections. Design: A literature review was performed in PubMed, Scopus, Google Scholar, and Cochrane databases in order to find articles published up to April 2019. Then, the pairwise method was used to compare the difference between the mean score of the clinical effectiveness of these two interventions before and after the intervention by the means of a non-direct method (the comparison of drugs with each other). Results: The analysis of 4 studies involving 767 patients in the ertapenem group and 728 patients in the piperacillin/tazobactam group showed that ertapenem can be 3% more effective than piperacillin/tazobactam (Weighted mean differences = 3.02, confidence interval (0.79-6.84) although the difference was insignificant (I-squared = 0.0%, P=0.98) Conclusions: In general, the findings demonstrated that there is no significant difference in the clinical effectiveness of ertapenem in comparison with piperacillin/tazobactam in adult patients with mild to moderate intra-abdominal infections.
