The prevalence of work-related musculoskeletal disorder among health care workers in Damascus, Syria. A cross-sectional study.

Background and Aims: Healthcare workers in particular frequently report Work-related musculoskeletal diseases (WRMSDs). The purpose of this study is to evaluate the prevalence and features of WRMSDs in residents from different specialties and trainee nurses from educational hospitals in Damascus, Syria. Methods: A cross-sectional survey was undertaken aiming at the medical residents and the trainee nurses working in the public health sector in 11 hospitals. The sample size was found to be 2016. In this study, a modified version of the Standardized Nordic Questionnaire was employed. Results: After the inclusion and exclusion criteria was the number of the participants 1855. In general, musculoskeletal pain was in the past week (69%) and the past 12 months (85%). Musculoskeletal pain in medical care practitioners was found to be linked to higher mean age (p = 0.0053) and body mass index (BMI) (p = 0.0437) in the last year. Females had a higher prevalence of WRMSDs than males (p = 0.0036), and those who were married also had a higher prevalence (p = 0.0218). Working longer hours per week and per month were associated with musculoskeletal pain in the previous 7 days (p = 0.0043 and p = 0.0003, respectively). Conclusion: WRMSD prevalence was 85% among our study participants in the previous year. The most common complaint was lower back pain. Aging, female gender, and increasing BMI have been associated with higher reporting of WRMSDs. Our results suggested that doctors were twice as susceptible to developing WRMSDs as nurses. These results highlight the increasing urgency for ergonomics training programs and effective interventions to reduce WRMSDs and enhance working conditions for healthcare professionals in Syria.

Stress, depression, anxiety, and quality of life among the healthcare workers during COVID-19 pandemic in Syria: a multi-center study.

BACKGROUND: The COVID-19 pandemic emerged as an expected source of stress and anxiety as the healthcare workers had to work for long hours in close contact with infected patients, thus increasing the probability of medical errors and threatening the patients' safety. This study aims to measure the levels of depressive symptoms, anxiety symptoms, and stress among Syrian healthcare workers and their quality of life during the COVID-19 pandemic. METHODS: A cross-sectional study was conducted in six central hospitals in Damascus, Syria. Data were collected from 1 to 30 June-2021. The Depression Anxiety Stress Scale-21 (DASS-21) was used to evaluate depression, anxiety, and stress among healthcare workers. Quality of life was assessed using the EUROHIS-QOL 8-item index. RESULTS: A total of 700 participants were included in this study. 61.6% (n = 431) were males and 38.4% (n = 269) were females. Younger ages (18-29 years old) were significantly associated with higher levels of depression and stress (p < 0.0083). Female healthcare workers had higher significant levels of anxiety (p < 0.05). Significant anxiety and stress levels were reported when healthcare workers had contact with COVID-19 patients, even if they had protective equipment (p < 0.05). Half of the participants (50%; n = 349) reported a good quality of life. CONCLUSION: Stress levels and depressive symptoms were remarkably higher in healthcare workers of ages 18 and 29 years old, whereas anxiety levels were significantly higher and more severe in female healthcare workers. Moreover, direct interaction with COVID-19 patients was associated with higher levels of stress and anxiety symptoms.

The Prevalence and Risk Factors of COVID-Stress Syndrome.

Background COVID-19 is a serious disease causing negative psychological effects such as nervousness, isolation, depression, and suicide ideation. The COVID Stress Scale was developed to better understand and assess COVID-19-related distress. University students are predicted to be negatively impacted by the COVID-19 outbreak due to their lack of psychological skills and high levels of academic stress. This study compares the prevalence of COVID stress syndrome (CSS) among university students in Syria and Jordan during the outbreak. The questionnaire used in the study covers multiple aspects and can be applied to future pandemics or infectious diseases. Methodology This is a cross-sectional study conducted in Syria and Jordan between September 1 and December 1, 2021, to evaluate CSS among university students. Data were collected from a convenience sample of 2525 students using a structured, validated, and published questionnaire. Ethical considerations were taken, and informed consent was obtained from participants. The questionnaire had two parts: participant characteristics and CSS. The data were analyzed using the Statistical Package for the Social Sciences (SPSS, IBM Corp., Armonk, NY), and the chi-square test was used to compare the CSS scale between the two countries. Result The study involved 2525 university students, mostly Syrian (63.6%) and Jordanian (36.4%), aged 18-24 (89.5%), and mostly single (95.6%). Over 50% of students lived in homes with three or more people. More than half reported good to excellent economic status; non-smokers accounted for over 50%. Regarding CSS, 39.8% had a high score, 28% average, 20% severe, and 12.2% low to mild. Jordanian male students and single Syrian students showed a higher probability of experiencing CSS symptoms. The number of people in the household, financial status, and field of study also played a significant role. Conclusion The COVID-19 pandemic has negative impacts beyond physical health, including the economy, education, and mental health. A stress scale has been developed to measure COVID-19 stress syndrome, which includes Danger and Contamination Fears (DAN), Socioeconomic Consequences Fears (SEC), Xenophobic Fears (XEN), Traumatic Stress Symptoms (TSS), and Compulsive Checking and Reassurance Seeking (CHE). Non-medical faculty students are more likely to acquire CSS symptoms than medical faculty students.

The Antioxidant and Proapoptotic Effects of Sternbergia clusiana Bulb Ethanolic Extract on Triple-Negative and Estrogen-Dependent Breast Cancer Cells In Vitro.

BACKGROUND: Sternbergia clusiana belongs to the Amaryllidaceae family and is recognized for the valuable biological activity of its major bioactive compounds. The aim of the current is to evaluate the anticancer effects of the ethanolic bulb extract of Sternbergia clusiana (ScBEE) on breast cancer cells in vitro and to further reveal the underlying cellular mechanism. METHODS: An MTS cell viability assay was performed on MDA-MB-231 and MCF-7 cells, along with cell cycle analysis, cell death ELISA, Western blot analysis and an ROS production assay to decipher the mechanism of death. LC-MS/MS was also performed to identify the chemical composition of this ethanolic extract. RESULTS: The results show a selective antiproliferative effect on both cell lines with no effect on normal mesenchymal stem cells. Further analysis suggested the activation of the apoptotic pathway as reflected by the increase in cellular and DNA fragmentation and alterations in apoptotic proteins such as Bax, Bcl-2 and c-PARP. ScBEE was also found to exhibit antioxidant effect, as shown by a decrease in ROS production. The underlying mechanism of action was explained by the presence of several bioactive compounds identified by LC-MS/MS, including alkaloids, terpenoids and phenols, which are elaborated in the manuscript. CONCLUSION: This study highlights the antioxidant and anticancerous properties of S.clusiana for breast cancer treatment.

The prevalence of stress among medical students in Syria and its association with social support: a cross-sectional study.

INTRODUCTION: Chronic stress can interrupt personal life and cause fatigue, inability to concentrate, and irritability. This study aims to determine the prevalence of stress and its associated factors among medical students in Syria and whether social support could be a protective factor against stress. METHODS: A cross-sectional study was conducted in the faculty of medicine of five Syrian universities. The Medical Student Stressor Questionnaire (MSSQ) was used to evaluate the stress caused by the possible sources of stress. And Social Support Questionnaire - short version (SSQ - short version) was used to assess the social support that medical students received from family, friends, and their fellow medical students using six questions. RESULTS: A total of 1472 medical students participated in the study. Among the total participants, 671 (45.6%) were males, and 801 (54.4%) were females. The majority of the participators had mild (50.6%; n = 745) and moderate (37.0%; n = 545) stress levels. Academic-related stressors were the most important cause of stress among undergraduate medical students. Social support was provided equally to both genders, and genders reported the same degree of satisfaction. CONCLUSION: Our results emphasize the importance of improving the curricula, providing mental health consultants for students, and paying more attention to the mental health of female students. Finally, students in their clinical years should also receive mental health care, decreasing their duties and providing more self-free time.

CO2 sequestration by propagation of the fast-growing Azolla spp.

Azolla is a group of aquatic floating plants that can achieve very high growth rates compared to other aquatic macrophytes, with a doubling time of 2-5 days under optimal growing conditions. The ability of Azolla to grow at such rapid rates allows for the opportunity of utilizing it as a method to sequester a significant amount of atmospheric CO2 in the form of biomass, which can be locked away to completely remove the carbon from the active carbon cycle, or which can be used in various applications such as animal feeds, biofertilizers, and biofuel production, which in turn will contribute to reduction in the fossil CO2 emissions. In this desktop study, the potential use of Azolla for mitigating the annual increase in the atmospheric CO2 levels was addressed, which were estimated at 18.9 billion tons of CO2 per year. A theoretical setup of 1-ha ponds was assessed to estimate the total Azolla growing area required for counterbalancing the annual atmospheric CO2 increase. Each 1-ha pond was found capable of capturing 21,266 kg of CO2 (C) per year. The calculated required total area to mitigate the total annual increase was estimated to be 1,018,023 km2 (equivalent to around a fifth of the Amazon forest area). Sensitivity analysis, which was based on the variations in the productivity of Azolla due to growing conditions, indicated that the required area would range between 763,518 and 1,527,036 km2. This study provides a novel natural method for CO2 sequestration that has lower environmental impacts compared to conventional sequestration technologies as an alternative green approach for mitigating the effects of fossil fuels.

Trinuclear heterobimetallic Ni2Ln complexes [L2Ni2Ln][ClO4] (Ln=La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, and Er; LH3=(S)P[N(Me)NCH-C6H3-2-OH-3-OMe]3): from simple paramagnetic complexes to single-molecule magnet behavior.

The reaction of LH3 with Ni(ClO4)(2).6H 2O and lanthanide salts in a 2:2:1 ratio in the presence of triethylamine leads to the formation of the trinuclear complexes [L2Ni2Ln][ClO4] (Ln=La (2), Ce (3), Pr (4), Nd (5), Sm (6), Eu (7), Gd (8), Tb (9), Dy (10), Ho (11) and Er (12) and L: (S)P[N(Me)NCH-C6H3-2-O-3-OMe]3). The cationic portion of these complexes consists of three metal ions that are arranged in a linear manner. The two terminal nickel(II) ions are coordinated by imino and phenolate oxygen atoms (3N, 3O), whereas the central lanthanide ion is bound to the phenolate and methoxy oxygen atoms (12O). The Ni-Ni separations in these complexes range from 6.84 to 6.48 A. The Ni-Ni, Ni-Ln and Ln-O phenolate bond distances in 2-12 show a gradual reduction proceeding from 2 to 12 in accordance with lanthanide contraction. Whereas all of the compounds (2-12) are paramagnetic systems, 8 displays a remarkable ST=(11)/2 ground state induced by an intramolecular Ni. . .Gd ferromagnetic interaction, and 10 is a new mixed metal 3d/4f single-molecule magnet generated by the high-spin ground state of the complex and the magnetic anisotropy brought by the dysprosium(III) metal ion.

Water quality assessment of Lebanese coastal rivers during dry season and pollution load into the Mediterranean Sea.

The chemical and microbiological properties of Lebanese perennial coastal rivers were studied during the dry season extending from July to September 2004. The results indicate significant levels of pollution in all eight rivers. Although many physical and chemical variables were within WHO guidelines for drinking water, coliform levels were unacceptably high indicating pollution from untreated sewage. The most polluted rivers in most categories were the Abu Ali and Antelias. With the exception of bacterial and phosphate loadings, Awali River provides the highest amount of pollution to the Mediterranean mainly due to its high water flow, although it is one of the least polluted rivers. The urgent need for controlling wastewater dumping into river streams is emphasized. The data obtained should serve as a reference point to assess the efficiency of planned wastewater treatment plants.
