Abstract: The need for cigarette consumption in Indonesia judging by the number of smokers is 64.5 million. As a result, each cigarette factory will produce continuously with one of the resources for production activities coming from human labor, where they are tasked with achieving company goals. However, in practice, human labor is always directed to have a high level of productivity by paying attention to the workload and fulfilling nutritional intake in order to minimize excessive fatigue and maintain stamina. This study was conducted to determine the partial impact of nutritional status and subjective fatigue level on the productivity of the cigarette-rolling workers at PT. X Kabupaten Malang. Where the model used is quantitative analysis with an analytical observational research design, namely a cross-sectional study. The instruments used include the International Fatigue Research Committee (IFRC) questionnaire, Glass Electronic Personal Scale with Camry brand model: EB9003, and Gea brand microtoise. The significance value of the nutritional status variable was 0.857 for the normal BMI category and 0.708 for the obese BMI category which showed no influence between nutritional status and productivity, and the significance value of the subjective fatigue level variable was 0.215 for the low subjective fatigue level category which showed no the effect of subjective fatigue level with productivity.

Human anatomy is perceived by health science students and educators to be a burdensome, challenging and labour-intense course. In order to enhance understanding of human anatomy, the use of student-centred approaches is encouraged, of which drawing is included. However, it is not explicitly known how nursing students in Kavango east region experience the use of drawing. This research was conducted to explore and describe the experiences of first-year nursing students from a resource-constraint setting on the use of drawing as a learning activity in a human anatomy course. A qualitative descriptive, explorative, and contextual study was conducted in Kavango east region, Namibia. Data were collected via focus-group interviews with 28 participants who were conveniently selected. A qualitative content analysis was followed, while trustworthiness was ensured according to the four principles of Lincoln and Guba. Ethical clearance and permission were granted by the School of Nursing Research Committee. The ethical principles of autonomy, non-maleficence, beneficence, and justice were adhered to. The experienced beneficial aspects of drawing are enhancement of course understanding, boosting creativity, and integration of theory into practice. Challenging aspects were related to lacking artistical skills, time constraints, complex and complicated drawings as well as a shortage of materials and learning resources. In order to improve drawing as a learning activity in human anatomy, recommendations were made for nursing students, educators and future researchers.

Objective: Since the properties of health-related quality of life measures vary across samples, studies directly comparing the properties of different measures can be useful in understanding their relative strengths and limitations. We aimed to compare the psychometric properties of the Health Utilities Index Mark III (HUI3) and the Multiple Sclerosis Impact Scale-29 (MSIS-29).Methods: In Spring 2020, North American Research Committee on Multiple Sclerosis (NARCOMS) Registry participants completed the HUI3, MSIS-29, Patient Determined Disease Steps (PDDS) and SymptoMScreen. For the HUI3 and MSIS-29 we assessed floor and ceiling effects, construct validity, and internal consistency reliability. We used relative efficiency to compare the discriminating ability of the two measures with respect to disability.Results: We included 5,664 participants in the analysis, with mean (SD) age 63 (10.1) years; 4,579 (80.8%) were women. For the HUI3 the mean (SD) score was 0.44 (0.32), for the MSIS-29 physical it was 34.0 (24.2) and for the MSIS-29 psychological it was 25.9 (20.4). Neither of the measures had floor or ceiling effects, and internal consistency reliability was > 0.70 for both. The HUI3 and MSIS-29 physical were strongly correlated (r = −0.78; 95%CI:−0.79,−0.77). The correlation between the HUI3 and MSIS-29 psychological was weaker but remained moderately strong (r = −0.64; 95%CI:−0.66,−0.63). After adjusting for sociodemographic and clinical factors, relative efficiency to discriminate between disability (PDDS) groups was highest for the MSIS-29 physical scale, followed by the HUI3.Conclusion: Both measures had adequate validity and reliability. The MSIS-29 physical discriminated between disability groups better than the HUI3.

INTRODUCTION: COVID-19 pandemic has caused disasters and disorders all over the world. India is also going through a challenging situation as the number of infected/positive cases is increasing day by day. Due to the crisis of COVID-19 education system has come to a halt as schools and colleges are closed to slow down and prevent the spread of infection. Nursing institution also closed down and online mode of teaching was done. Hands on training is required to relate theory in to practice which was thwarted due to the pandemic COVID-19. Nursing students were panic and apprehensive about the situation even though they were asked to stay in the hostel. OBJECTIVE: To assess the level of stress and anxiety among the nursing students and to associate the level of stress and anxiety with selected demographic variables. METHODS: The study design was descriptive cross-sectional. The study was conducted in College of Nursing CIHSR among the 3rd Year GNM, 3rd Year and 4th Year B. Sc. Nursing Students. Total enumerative sampling method was used and sample size was 95. Standardized instrument on Perceived stress scale for assessing stress and Corona anxiety scale for assessing anxiety regarding COVID – 19 were used for the study. The study was approved by nursing research committee and informed consent was taken. Data was analysed using descriptive and inferential statistics. RESULTS: The study found that 80(84.2%) had moderate stress out of 95 respondents, 8 (8.4%) had high perceived stress, and 7(7.4%) had low level of stress. In the Coronavirus anxiety scale majority of the respondents, 91(95.8%) have little to no dysfunctional anxiety out of 95 respondents, 2 (2.1%) had possible dysfunctional anxiety and 2 (2.1%) had probable dysfunctional anxiety. There were no significant association between level of stress, anxiety and demographic variables. CONCLUSION: Study reveals that majority of the students had moderate level of stress and little to no dysfunctional anxiety regarding COVID - 19. Thus leaflet regarding cause, spread, prevention and management of COVID-19 given to each student to reduce their stress and anxiety.

Objectives: The use of herbal medicines as non-conventional treatment is popular, especially in developing countries where people suffering from chronic diseases as diabetes mellitus are more likely to use herbal medicines along with conventional medicines. However, their simultaneous use may concur serious drug interactions and may therefore result in a serious outcome. The present study was designed to identify the most commonly used herbal medicines and conventional anti-diabetic medications among Saudi population. Methods: A cross-sectional survey was developed and piloted.Data were retrieved and manually entered in Excel 2016. Frequencies and percentages were utilized to perform descriptive analysis. The study was approved by the Scientific and Research Committee of the main hospital taking part in the study. Results: A total of 347 responses were recorded (69.4% response rate). 54% of participants were male, 53% were between the age of 41 and 64 years, and 35.5% had no formal education. Black tea, Peppermint, ginger, green tea, olive oil, and black seed were among the frequently mentioned herbal medicines. Black tea was used by the majority of patients (80%) while peppermint and ginger were used by more than half of patients, i.e., (56.5%) and (52.7%) respectively. Least common herb used by patients was Artemisia species (2.8%). A majority of patients (53.4%) used traditional medicine at least once daily, and 83% used traditional medicine without their physician's prescription. Conclusion: Concomitant use of herbal and conventional anti-diabetic medication was a common practice among patients in Saudi Arabia, therefore, pharmacists-led educational programs should target both prescribers and general public about the possible interactions/risks of herbal medicines.

IntroductionEmotional disorders (EDs) have become the most prevalent psychological disorders in the general population, which has boosted the economic burden associated with their management. Approximately half of the individuals do not receive adequate treatment. Consequently, finding solutions to deliver cost-effective treatments for EDs has become a key goal of today’s clinical psychology. Blended treatments, a combination of face-to-face and online interventions, have emerged as a potential solution to the previous. The Unified Protocol for the Transdiagnostic Treatment of EDs (UP) might serve this purpose, as it can be applied to a variety of disorders simultaneously and its manualised format makes it suitable for blended interventions.Methods and analysisThe study is a multicentre, randomised, superiority, clinical trial. Participants will be 310 individuals with a diagnosis of an ED. They will be randomised to a treatment as usual (individual cognitive behavioural therapy) or a UP condition in a blended format (face-to-face individual UP +online, app-based UP). Primary outcomes will be ED diagnostic criteria and depression and anxiety symptoms. Cost efficiency of the intervention, app usability, as well as opinion and confidence in the treatment will also be evaluated. Assessment points will include baseline and 3 months, 6 months and 12 months after UP treatment.Ethics and disseminationThe study has received approvals by the Ethics Research Committee of Navarra, Castellón, Euskadi, Castilla y León, Extremadura, Lleida and Aragón. The study is currently under an approval process by the Ethics Research Committees of all the remaining collaborating centres. Outcomes will be disseminated through publication in peer-reviewed journals and presentations at international conference meetings.Trial registration numberNCT04304911.

When I posted to LinkedIn some time back to generate publicity for my Geophysical Society of Houston technical lunch talk on beam tomography, one of the interesting comments from a colleague at a large service company was that beam technology is “a technology with many benefits that unfortunately is commonly regarded as old school/low tech.” I loved receiving the comment because it gives me an opportunity to talk about one of my favorite business concepts that I always look to apply: high-tech low tech. “High tech” is a term for new technology that incorporates advanced features. “Low tech” is old-school technology. I'll start with an example: the story of the Nest thermostat.
