Abstract

Study aim: This study aimed to investigate the impact of physical activity on the mental health characteristics of a sample of university students from Paraguay, assessing their daily physical activity and the prevalence of depression, anxiety, and stress.

Materials and methods: This observational, descriptive, prospective, cross-sectional study included 317 university students. Participants were assessed using the International Physical Activity Questionnaire (IPAQ) to categorize their physical activity levels and the Depression, Anxiety, and Stress Scale-21 (DASS-21) to measure mental health characteristics. Data analysis utilized descriptive statistics, Pearson’s correlation, and chi-square tests to explore associations between physical activity and mental health outcomes.

Results: The results indicated that 49.5% of the participants were engaged in low levels of physical activity, while 20.2% and 30.3% reported high and moderate activity levels, respectively. Mental health assessments showed high prevalence rates for depression (65.3%), anxiety (68.5%), and stress (66.6%). Inverse correlations were found between total physical activity and each mental health parameter: depression (r = –0.167, p = 0.003), anxiety (r = –0.141, p = 0.012), and stress (r = –0.133 p = 0.018). Thus, higher levels of physical activity were associated with lower levels of depression, anxiety, and stress.

Conclusions: This study confirmed a significant inverse correlation between physical activity and common mental health issues. The promotion of physical activity may be a protective factor against depression, anxiety, and stress in this population. These findings support the need for university health programs to encourage physical activity as a strategic approach to enhance students’ mental health.

Published: December 2024

Objectives:
Blood donation for transfusion as a life-sustaining procedure and an integral part of health system can save lives and improve health of recipients. The aim of the study is to explain volunteer and repeated donation motivating factors and barriers among non-donors in Kabul, Afghanistan.

Material and Methods:
A comparative cross-sectional study among blood donors and non-donors was conducted using the convenience sampling method in Kabul, Afghanistan in 2020. Data were managed and analyzed using Epi Info version 7.2.1.

Results:
From a total of 495 study participants, 244 (49%) were donors and 251 (51%) were non-donors with mean age of 33.19 ± 10.1 and 30.31 ± 12.01, respectively. Among donors, 151 (62%) were volunteers and almost half of them, 121 (49%) donated their blood for the 1st time. Willingness of Allah as motivating factor was reported among 171 (70%) of donors and associated with volunteer (χ2 = 44.5, P < 0.001) and repeated donation (χ2 = 10.89, P < 0.001). In addition, rescuing someone’s life was stated by 70 (29%) of donors and only associated with repeated donation (χ2 = 6.01, P < 0.01). As barrier, 120 (48%) of non-donors were concerned on health risks of blood donation with an association found with willingness to donate blood in the future among this category (χ2 = 22.56, P < 0.001).

Conclusion:
Among volunteer donors, Willingness of Allah was the most prominent motivating factor while along this factor, rescuing someone’s life was mostly reported among repeated donors. Concerns about health risks of blood donation were the highest reported barrier among non-donors in contrast to other barriers. Religious and altruistic factors motivated blood donors to volunteer and repeated donation while misinformation about blood donation hindered this effort. Relying on religious informative channels could help in the development and sustaining volunteer donors’ pool in Afghanistan.

The objective of the study is to assess the performance of individual biochemical parameters on a sigma scale and also to do root cause analysis and take corrective actions for the parameters with poor performance to improve the quality of our clinical laboratory.

Materials and Methods:
This is a retrospective and prospective study done in the central laboratory of a tertiary care hospital from January 2023 to September 2023. The daily internal quality control (IQC) data and monthly external quality assessment service data for 10 biochemical parameters from January 2022 to December 2022 were collected retrospectively and from April 2023 to September 2023 prospectively. Parameters with poor sigma performance and root cause analysis were done, and corrective actions were taken. Data were collected prospectively for the next 4 months (April 2023–September 2023), and sigma was calculated.

Statistical analysis:
Data were input into Microsoft Excel and analyzed using Stata version 14.

Results:
Out of the ten, 7 parameters at level 1 and five at level 2 IQC showed sigma values between 3 and 6, whereas 2 parameters showed poor performance at both the quality control (QC) levels with sigma metrics values <3. With quality goal index and root cause analysis, the source of error was detected and corrected.

Conclusions:
Sigma metric analysis is a tool to determine the performance of QC design. This gives the laboratory a select the right QC strategy. This will help to save time, effort, unnecessary runs, calibration, and reagent waste, which affect the outcome of turnaround time.

Published: December 2024

Применение инсектицидов из новых химических групп может помочь в преодолении резистентности синантропных членистоногих к традиционным препаратам. Рассмотрены 4 группы перспективных для применения в медицинской дезинсекции инсектицидов — изоксазолины, диамиды, мета-диамиды, тетроновые/тетрамовые кислоты. В программы интегрированного пест-менеджмента следует вводить как можно больше методов физического или механического уничтожения насекомых — мониторинг заселенности помещений с помощью клеевых ловушек, применение специальных пылесосов, термообработки, внедрение лазерных технологий. Показана необходимость образовательных программ для населения.
The use of insecticides from new chemical groups can help overcome the resistance of synanthropic arthropods to traditional drugs. Four groups are considered — isoxazolines, diamides, metadiamides, tetronic and tetramic acids, promising for use in medical disinsection. Integrated pest management programs should include as many methods of physical or mechanical destruction of insects as possible — monitoring with glue traps, vacuuming, heat treatment, laser technologies. The need for educational programs for the population is shown.

Published: November 2024

Objective: The study aims to balance liquidity and profitability and its impact on financial performance, one of the most serious problems faced by banks in all countries of the world, because it is an important element that maintains the continuity of the bank’s work. The study aimed to identify the relationship between the three variables and their impact on Iraqi commercial banks.

Theoretical Framework: This topic presents the most important concepts and theories on which the research is based. Liquidity, profitability and financial performance stand out, providing a solid basis for understanding the context of the investigation.

Method: This study is based on the descriptive analytical correlational approach, which is widely used in human research and studies. The study population is represented by (44) Iraqi commercial banks listed on the Iraq Stock Exchange. The researcher chose (2) banks from these banks that expressed cooperation with him in providing... The data is unlike other banks that did not express cooperation due to fear of leaking some of their information, as they claimed, which they consider important in the nature of their work, in addition to the lack of response from employees in some banks to answer the questions of the questionnaire. The sample members were represented by workers in the banks in the study sample at various levels. Administrative, as (415) questionnaires were distributed to individuals, electronically.

Results and Discussion: The results of the study found that there is a direct effect between liquidity and financial performance, directly and indirectly, in whole and in part, in addition to that the profitability variable plays a mediating role between liquidity and financial performance, and this is what leads us to the fact that the balance between profitability and liquidity leads to improved financial performance in Iraqi commercial banks.

Research Implications: The practical and theoretical implications of this research are discussed, providing insight into how the findings can apply or influence practices in the area of ​​liquidity, profitability and financial performance. These reflections may include the banks sampled for the study and the services they provide.

Originality/Value: The importance of this study came from the scarcity of studies that attempted to define and understand the nature of the relationship between variables (liquidity, profitability, and financial performance), as well as the current study’s attempt to address a realistic problem that directly affects the performance of employees in Iraqi banks.

BURNOUT AND OCCUPATIONAL STRESS AMONG SCHOOLTEACHERS DURING THE COVID-19 PANDEMIC IN BANGALORE URBAN AND BANGALORE RURAL
Authors: R Pushpalatha , E Keshamma 
Published: December 2024

Burnout is a psychological condition brought on by ongoing stress that impacts people’s feelings, mental health, and physical behaviour. Burnout is more common among those whose jobs require communication with a client or a third party. Burnout predicts intention to leave and actual job turnover. A negative perception of the profession can lead to progressive absenteeism and, finally, to withdrawal from teaching. Burnout has historically been linked to the teaching profession. Teacher shortages are not a new issue. Shortages began in the mid-1980s due to increasing student enrolments and decreasing numbers of college graduates becoming teachers. During the pandemic a wave of change disrupted the education of the students. Both the students and the teachers were forced to adapt in a short time to new ways of working that include social distancing in classrooms, hybrid teaching and virtual instructions. teachers have reported increased levels of anxiety, difficulties in communication and a lack of administrative support. All these new stressors proximal to burnout added to the fear generated by COVID-19, which almost all people have experienced. Teachers are most valuable assets to any country who part their knowledge and guide the young minds to be a contributing citizen of the nation. The teachers are often pressurized with huge demands which usually leads to a lot of stress. Work related stress negatively affects the performance of the teachers. Majority of teachers perceived their work-related stress due to dependent variables like gender, education, family income and economic instability. Job insecurity, poor students’ behaviour, ineffective leadership at departmental levels results in stress level of teachers and it also results in psychological distress among teachers. Educational status and years of experience of teachers are the factors responsible for creating stress among teachers. The aim is to study the stress and burnout among the schoolteachers. The sample consisted of 120 schoolteachers working in government and private schools as well as in rural and urban areas. Both male and female teachers constituted the sample for study. The teachers were residing in Bangalore urban and Bangalore rural areas. The teachers were administered the stress and burnout questionnaires. A purposive sampling design was opted for the study. The mean, SD, and ‘t’ was computed using appropriate statistical measures. The result revealed that there was a significant difference in stress and burnout between schoolteachers of urban and rural areas as well as male and female teachers.
