B56δ long-disordered arms form a dynamic PP2A regulation interface coupled with global allostery and Jordan's syndrome mutations.

Intrinsically disordered regions (IDR) and short linear motifs (SLiMs) play pivotal roles in the intricate signaling networks governed by phosphatases and kinases. B56δ (encoded by PPP2R5D) is a regulatory subunit of protein phosphatase 2A (PP2A) with long IDRs that harbor a substrate-mimicking SLiM and multiple phosphorylation sites. De novo missense mutations in PPP2R5D cause intellectual disabilities (ID), macrocephaly, Parkinsonism, and a broad range of neurological symptoms. Our single-particle cryo-EM structures of the PP2A-B56δ holoenzyme reveal that the long, disordered arms at the B56δ termini fold against each other and the holoenzyme core. This architecture suppresses both the phosphatase active site and the substrate-binding protein groove, thereby stabilizing the enzyme in a closed latent form with dual autoinhibition. The resulting interface spans over 190 Šand harbors unfavorable contacts, activation phosphorylation sites, and nearly all residues with ID-associated mutations. Our studies suggest that this dynamic interface is coupled to an allosteric network responsive to phosphorylation and altered globally by mutations. Furthermore, we found that ID mutations increase the holoenzyme activity and perturb the phosphorylation rates, and the severe variants significantly increase the mitotic duration and error rates compared to the normal variant.

Quantitative proteomics and phosphoproteomics of PP2A-PPP2R5D variants reveal deregulation of RPS6 phosphorylation via converging signaling cascades.

Genetic germline variants of PPP2R5D (encoding: phosphoprotein phosphatase 2 regulatory protein 5D) result in PPP2R5D-related disorder (Jordan's Syndrome), which is characterized by intellectual disability, hypotonia, seizures, macrocephaly, autism spectrum disorder, and delayed motor skill development. The disorder originates from de novo single nucleotide mutations, generating missense variants that act in a dominant manner. Pathogenic mutations altering 13 different amino acids have been identified, with the E198K variant accounting for ∼40% of reported cases. However, the generation of a heterozygous E198K variant cell line to study the molecular effects of the pathogenic mutation has been challenging. Here, we use CRISPR-PRIME genomic editing to introduce a transition (c.592G>A) in a single PPP2R5D allele in HEK293 cells, generating E198K-heterozygous lines to complement existing E420K variant lines. We generate global protein and phosphorylation profiles of WT, E198K, and E420K cell lines and find unique and shared changes between variants and WT cells in kinase- and phosphatase-controlled signaling cascades. We observed ribosomal protein S6 (RPS6) hyperphosphorylation as a shared signaling alteration, indicative of increased ribosomal protein S6-kinase activity. Treatment with rapamycin or an RPS6-kinase inhibitor (LY2584702) suppressed RPS6 phosphorylation in both, suggesting upstream activation of mTORC1/p70S6K. Intriguingly, our data suggests ERK-dependent activation of mTORC1 in both E198K and E420K variant cells, with additional AKT-mediated mTORC1 activation in the E420K variant. Thus, although upstream activation of mTORC1 differs between PPP2R5D-related disorder genotypes, inhibition of mTORC1 or RPS6 kinases warrants further investigation as potential therapeutic strategies for patients.

Inborn Errors of Immunity in Jordan: First Report from a Tertiary Referral Center.

PURPOSE: Inborn errors of immunity (IEI) are a heterogeneous group of diseases with variable clinical phenotypes. This study was conducted to describe the epidemiology, clinical presentations, treatment, and outcome of IEI in Jordanian children. METHODS: A retrospective data analysis was conducted for children under 15 years diagnosed with IEI from the pediatric Allergy, Immunology, and Rheumatology Division-based registry at Queen Rania Children's Hospital, Amman, Jordan, between 2010 and 2022. RESULTS: A total of 467 patients, 263 (56.3%) males and 204 (43.7%) females, were diagnosed with IEI. The mean age at symptom onset was 18 months (1 week to 144 months), a positive family history of IEI was reported in 43.5%, and the consanguinity rate was 47.9%. The most common IEI category was immunodeficiencies affecting cellular and humoral immunity at 33.2%, followed by predominantly antibody deficiencies at 16.9%. The overall median diagnostic delay (range) was 6 (0-135) months; patients with a positive family history of IEI had a statistically significant shorter diagnostic delay. Pulmonary and gastrointestinal clinical features were the most common at 55.2% and 45.6%, respectively. The overall mortality was 33.2%; the highest rate was reported in severe combined immunodeficiency at 56.2%. CONCLUSIONS: The high minimal estimated IEI prevalence at 16.2/100,000 Jordanian children compared to the regional and worldwide data, with the diversities in clinical presentation and distribution of IEI categories in our cohort point to unique features of IEI in Jordanian children, call for national registry establishment, regional and international collaborative networks.

Geochemical dispersion of gold-bearing quartz veins in the Wadi Abu Khusheiba area in Southern Jordan.

This study delves into the geochemical dispersion of gold-bearing quartz veins in the Wadi Abu Khusheiba area, southern Jordan, with a focus on uncovering the complex patterns of mineralization and their geological significance. Employing an in-depth geochemical analysis of 24 rock samples from the region, we identified that these samples are predominantly hosted by oversaturated rhyolitic rocks, characterized by high SiO2 content and abundant free Quartz and orthoclase minerals. The mineralized zone of the quartz veins is particularly notable for its gold and silver concentrations, with maximum values reaching up to 5 ppm for gold and 18 ppm for silver. Our investigation into the elemental correlations revealed nuanced relationships, dependent on the 21 sample and analyzed at confidence level of (85%). Contrary to initial assumptions, we did not find a significant positive correlation between gold (Au) and arsenic (As), nor significant negative correlations between gold and other trace elements. These insights are critical for understanding the geochemical behavior of gold in the area and offer a nuanced view of elemental associations. The results of this study are significant for both academic research and practical exploration. They enhance our comprehension of the geological history and mineralization processes in Wadi Abu Khusheiba, providing valuable data that can inform future exploration strategies and deepen our understanding of mineral deposition in similar geological settings. This research not only contributes to the scientific community's knowledge of the area's geochemistry but also has potential implications for the mining and exploration industries.

Evaluation of awareness and performance towards COVID-related disinfectant use: a comparative study between Jordan and United Arab Emirates.

BACKGROUND: The World Health Organization recommended the use of chemical-based disinfectants as an effective prevention of the COVID-19 pandemic. However, calls for poisoning were reported in several medical centers. The widespread use of chemical-based disinfectants as a preventive measure during the COVID-19 pandemic has underscored potential gaps in community awareness and performance, posing health risks. This study evaluates and compares levels of awareness and performance regarding the safe use of disinfectants in Jordan and UAE. METHODS: The study was conducted between October 2022 and June 2023 via an online questionnaire. Data of respondents from Jordan (n = 828) and UAE (n = 619) were analyzed using SPSS. ANOVA, Mann-Whitney, and Kruskal-Wallis tests evaluated significant differences in awareness and performance levels across different demographic groups in Jordan/UAE and between them. Spearman's correlation test examined the correlation between awareness and performance among respondents. Multinomial logistic regression analysis explored associations between various variables and awareness/performance levels within each population. RESULTS: Findings reveal weak awareness (72.4% and 9.03% in UAE and Jordan, respectively) and moderate performance level (98.8% in UAE and Jordan), with a weak correlation (UAE, rho = 0.093; Jordan, rho = 0.164) observed between the two countries (P < 0.05). Multinomial logistic regression analysis indicates gender-related associations with awareness levels and education-related associations with performance levels. CONCLUSIONS: The study emphasizes the urgent need for awareness campaigns and workshops to promote safer disinfectant practices to develop effective interventions aligning with sustainable development goals.

Healthcare equity in focus: bridging gaps through a spatial analysis of healthcare facilities in Irbid, Jordan.

In the Irbid Governorate, Jordan, equitable healthcare facility distribution is vital to ensuring healthcare accessibility and improving public health outcomes. This study investigated the spatial distribution, accessibility, and conformity of healthcare facilities to the Ministry of Health standards to identify areas requiring improvement. Using geographic information systems (GIS), three spatial analyses were conducted: nearest neighbor analysis, buffer analysis, and service area analysis. These analyses comprehensively assessed the healthcare landscape, revealing a random spatial distribution pattern of healthcare facilities; and indicating an absence of structured organization. The buffer analysis revealed concentrations in specific regions, while others were underserved. The Service Area Analysis revealed significant healthcare access challenges, especially in remote areas. The healthcare resource distribution of the Irbid governorate fell short of national and international standards, emphasizing the need for improvements. To address these disparities, policymakers and healthcare authorities should focus on equitably redistributing resources, tailoring allocation to local needs, improving remote area infrastructure, and refining government policies. Continuous monitoring and evaluation are imperative to ensure alignment with international standards and achieve healthcare equity. The insights from this case study provide valuable guidance for regions facing similar healthcare distribution challenges.

Validation of an Arabic version of the female version of The Sexual Dysfunctional Beliefs Questionnaire: a factor analysis study.

Several questionnaires have been developed to evaluate female sexual dysfunction (FSD) and sexual health problems. However, there is a lack of validated versions of these questionnaires in Arabic. One of the most used instruments is the female version of The Sexual Dysfunctional Beliefs Questionnaire (SDBQ). The current study aimed to validate an Arabic version of the SDBQ. The Arabic version of SDBQ-Female was incorporated into an online questionnaire using and distributed among Jordanian Facebook groups and women-only groups. Factor analysis was performed to investigate evidence for the validity of the questionnaire. 530 females (mean age 30 years, SD = 9) completed the questionnaire. Principal component analysis produced the final model composed of 24 items distributed across four factors: Sexual Desire & Pleasure, Affection Primacy, Sexual Conservatism and Age-Related Beliefs. Confirmatory factor analysis was conducted, and fit indices were acceptable (CMIN/DF = 2.52, GFI = 0.91, AGFI = 0.89, CFI = 0.90, SRMR = 0.05 and RMSEA = 0.05). Income level and marital status both influenced FSD beliefs, with higher scores associated with higher income and being single. The Arabic version of the SDBQ-female demonstrated evidence of validity and reliability. Additional research is necessary to explore beliefs related to FSD within an Arabic context.

This study provides evidence for the validity and reliability of an Arabic questionnaire for assessing female sexual dysfunction (FSD) among Jordanian women recruited through Facebook. Women's income level and marital status influenced their FSD beliefs. Further research is needed to explore these beliefs in an Arabic context.

Factors affecting the quality of working life among nurses caring for Syrian refugee camps in Jordan.

OBJECTIVES: The global refugee crisis, exacerbated by the Syrian war, has placed tremendous strain on Jordan's healthcare system and infrastructure, notably impacting nurses working in refugee camps. The aim to identify factors influencing nurses' Quality of life at work (QWL) and understand their significance in crisis healthcare environments. METHODOLOGY: A cross-sectional study was conducted in multiple healthcare facilities within Syrian refugee camps. A convenient sample of 166 nurses participated, and data were collected using the Brook's Quality of Nursing Work Life Survey. Data analysis included descriptive and inferential (one-way ANOVA) statistics. Significance level was set at 0.05. RESULTS: Nurses in this study generally reported a moderate QWL, with an average score of 152.85, indicating that their overall work experience falls into the moderate range. The study found that nurses perceived their work-life/home-life balance (mean score 25.79), work design (mean score 35.71), work context (mean score 71.37), and work world (mean score 19.96) at levels indicative of moderate satisfaction. There were no statistically significant differences in QWL among participating nurses, suggesting that factors other than demographic characteristics may play a more influential role in determining nurses' QWL in the unique context of refugee caregiving. CONCLUSION: This study underscores that working within refugee healthcare missions and recommends targeted interventions to enhance their well-being.

The prevalence of probable overactive bladder and associated risk factors among medical students in Jordan: a cross-sectional study.

BACKGROUND: To discuss the impact of overactive bladder (OAB) on medical students. overactive bladder. is a chronic condition that causes sudden and intense urges to urinate, which can have significant physical and psychological effects on patients' lives. The prevalence of OAB among medical students is relatively high, with some studies reporting rates as high as 35.4%. This research aims to shed light on the prevalence rates and risk factors associated with OAB among medical students in Jordan. METHODS: A cross-sectional study was conducted using an online self-reported questionnaire as the study tool. The questionnaire collected the sociodemographic, health, and academic characteristics of medical students, as well as the new 7-item OABSS score. RESULTS: Out of the total sample of medical students surveyed (n = 525), 44.5% reported experiencing symptoms of OAB. Furthermore, the analysis also revealed that there was a significant difference in the prevalence of OAB between the ages of medical students. In addition, the study also found that there was a significant association between OAB symptoms and basic years, positive history of diagnostic UTI, positive history of recent trauma, high stress, and taking certain medications. CONCLUSIONS: The study highlights the need for further research in this area and emphasizes the possible implications of OAB for medical students, including the need for additional support and resources to manage the condition.

Insights into systemic lupus erythematosus: a retrospective observational study of clinical features, autoantibodies, and gender-related differences.

This study aims to analyze the clinical and immunologic features of SLE in Jordan, while also investigating the impact of age and gender on disease presentation. The study included 275 patients diagnosed with SLE. Data were collected through meticulous patient interviews and thorough examination of patient hospital records. The cohort exhibited a mean age of 36.8 ± 12.9 years, with an average disease duration of 7.0 ± 7.8 years. The mean age at diagnosis was 29.9 ± 12.1 years, and the female to male ratio was 7.8:1. The most frequently observed symptoms were arthralgia (90.2%), fatigue (80.7%), hematologic manifestations (62%), photosensitivity (60.7%), Raynaud's phenomenon (53.5%), and malar rash (50.9%). The frequencies of various autoantibodies were as follows: ANA (96.7%), anti-dsDNA (39.6%), anti-SSA/Ro (32.8%), anti-Sm (21.8%), anti-U1-RNP (20.6%), and anti-SSB/La (15.5%). Male patients tended to receive a diagnosis at a younger age and exhibited a higher likelihood of experiencing severe manifestations compared to females. Additionally, juvenile onset patients demonstrated an increased likelihood of fever, photosensitivity, myositis, and anti-dsDNA autoantibodies, while adult onset patients were more predisposed to having anti-Ro, anti-La, and RF autoantibodies. This study reveals that the most prevalent manifestations of SLE in the Jordanian cohort encompassed arthralgia, fatigue, and hematologic manifestations. The prevalence of alopecia and Raynaud's phenomenon exceeded that observed in other published cohorts, while arthritis and discoid rash were less frequently encountered. The study highlights that males are more susceptible to developing severe manifestations of SLE compared to females.

Giant cell arteritis: insights from a monocentric retrospective cohort study.

Giant cell arteritis (GCA), more common in Northern European populations, has limited data in Arabcountries. Our study reports GCA's clinical manifestations in Jordan and reviews published research on GCA across Arab nations. In this retrospective analysis, GCA patients diagnosed from January 2007 to March 2019 at a Jordanian academic medical center were included through referrals for temporal artery biopsy (TAB). A comprehensive search in PubMed, Scopus, and the DOAJ (Directory of Open Access Journals) databases was conducted to identify all relevant English-language manuscripts from Arab countries on GCA without time limitations. Among 59 diagnosed GCA patients, 41 (69.5%) were clinically diagnosed with a negative TAB, and 19 (30.5%) had a positive result. Females comprised 74.6% (n = 44) with 1:3 male-female ratio. The mean age at diagnosis was 67.3 (± 9.5) years, with most presenting within two weeks (n = 40, 67.8%). Headache was reported by 54 patients (91.5%). Elevated ESR occurred in 51 patients (78%), with a mean of 81 ± 32.2 mm/hr. All received glucocorticoids for 13.1 ± 10 months. Azathioprine, Methotrexate, and Tocilizumab usage was 15.3% (n = 9), 8.5% (n = 5), and 3.4% (n = 2), respectively. Remission was observed in 57.6% (n=34), and 40.7% (n = 24) had a chronic clinical course on treatment. Males had higher biopsy-based diagnoses (p = .008), and biopsy-diagnosed patients were older (p = .043). The literature search yielded only 20 manuscripts originating in the Arab world. The predominant study types included case reports and retrospective analyses, with only one case series and onecase-control study.

The hidden burden of dysmenorrhea among adolescent girls in Palestine refugee camps: a focus on well-being and academic performance.

BACKGROUND: Dysmenorrhea (painful menstruation) is a condition that may have a profound effect on adolescent girls' health status and well-being. It can impede their engagement in daily activities and hamper their regular school attendance. This study aims to explore the relationship between dysmenorrhea, well-being, and academic performance among adolescent girls living in Palestine refugee camps in the West Bank and Jordan. METHODS: We conducted a household survey between June and September 2019, with a total sample of 2737 adolescent girls 15 to 18 years old. Dysmenorrhea severity was assessed using the Working Ability, Location, Intensity, Duration of pain Dysmenorrhea scale (WaLIDD). The WHO-5 scale was used to evaluate the girls' overall well-being. Menstrual academic disruption (MAD) was measured using a self-reported scale. Multiple linear regression models were employed to evaluate the association between dysmenorrhea, well-being, and academic performance. Directed Acyclic Graphs (DAGs) were employed to identify variables for control in regression models. RESULTS: The mean dysmenorrhea score was 6.6 ± 2.6, with 37.9% and 41.2% expressing moderate and severe symptoms, respectively. The mean WHO-5 score was 58.7 ± 25.1, and 34.9% reported a low well-being status. The mean MAD score was 3.1 ± 3.3. 26% reported missing school due to dysmenorrhea, 36% said dysmenorrhea impacted their ability to concentrate, and 39% were unable to study for tests, and complete homework. The first regression analysis showed a reduction of 1.45 units in WHO-5 score for each unit increase in dysmenorrhea. The second regression analysis showed a non-linear increase in MAD score for increasing dysmenorrhea. For each dysmenorrhea score less than 4 (mild) there was a modest increase in MAD scores (coefficient 0.08, p-value = 0.006), and for each dysmenorrhea score above 4 there was a stronger increase in MAD scores (coefficient 0.95, p < 0.001). CONCLUSION: Dysmenorrhea poses significant challenges to the well-being and academic performance of adolescent girls living in Palestine refugee camps. Collaborative efforts and multifaceted approaches are crucial to address dysmenorrhea effectively. This involves research, targeted interventions, culturally sensitive strategies, and fostering a supportive environment that empowers girls to thrive academically and beyond.

The burden of Cardiovascular diseases in Jordan: a longitudinal analysis from the global burden of disease study, 1990-2019.

BACKGROUND: Cardiovascular Disease (CVD) is the leading cause of mortality worldwide. While countries in the Arab world continue to lack public health data and be severely understudied in health research, previous research has shown that compared to 1990, CVDs had a higher burden of disease in the Arab World in 2010. Jordan, a middle-income Arab country, is profiled with unique attributes such as a dual-sector healthcare system, political stability, and its role as a haven for refugees and migrants. These distinctive factors emphasize Jordan's suitability as a case study. This investigation aims to quantify CVD burden in Jordan and identify risk factors, contributing to a broader understanding of health challenges in the Arab region and beyond. METHODS: The Global Burden of Disease (GBD) dataset was used to estimate prevalence, death, and disability-adjusted life-years (DALYs) as age-standardized rates from 1990 to 2019. We calculated percentage change for nine specific CVDs and reported trends by gender and age groups. Additionally, data on twelve a priori selected behavioral, clinical, and environmental risk factors attributing to overall age-standardized CVDs DALY were reported per 100,00 population. RESULTS: In 2019, the age-standardized CVD prevalence, death, and DALYs rates in Jordan were 7980 (95% uncertainty interval [UI] 7629, 8360), 248 (95% UI 211, 288), and 4647 (95% UI 4028, 5388), respectively. Despite an increase in the absolute number of mortality and prevalence, between 1990 and 2019, the age-standardized prevalence, death, and DALYs rates all decreased by 5.5%, 45.1%, and 46.7%, respectively. In 2019, the leading risk factors contributing to overall age-standardized CVDs DALY per 100,000 population were high systolic blood pressure, high BMI, dietary risks, and high LDL cholesterol. CONCLUSION: Despite decreasing burden rate of CVDs in Jordan between 1990 and 2019, CVDs remain the leading cause of mortality in Jordan, with an increase in the total number of prevalence and mortality. Overall, this contributes to increased healthcare costs. Further research is required to quantify the burden of CVDs and understand it better. Intervention measures and policies tailored to specific CVDs should be designed to reduce the burden of CVDs in Jordan.

Identifying training needs of practising community pharmacists in Jordan-a self-assessment study.

BACKGROUND: Being the professional membership body for pharmacists in Jordan, the Jordan Pharmacists Association (JPA) took the initiative to establish a training centre for practising pharmacists. This study aims to identify the self-assessed training priorities of community pharmacists in Jordan. METHODS: In the period between August and October 2022, an online self-administered questionnaire was distributed using a variety of participants' identification and recruitment approaches. The questionnaire targeted currently practising community pharmacists. Data were analysed descriptively and inferentially. RESULTS: In total, 470 community pharmacists participated in this study. Of 470 participants, 307 (65.3%) were employees, of which 206 were full-time employees. Results showed that only 97 (21%) had access to an in-house training programme or scheme. Self-assessment of training needs highlighted differences between the three competencies clusters. While administrative and managerial skills and competencies were more frequently prioritised on average than the other two clusters, interpersonal and communication skills were needed the least. Evidence showed a significant difference between female and male participants regarding the need for training addressing maternity and early childhood health training issues. Lastly, the role-based comparison showed that, compared to pharmacy owners, employees had a significantly higher need for training related to bookkeeping and taxation returns preparation and how to handle and manage records of narcotic and controlled medicines. CONCLUSIONS: If training and development programmes are tailored to address specific needs in administrative, clinical, and interpersonal competencies, community pharmacists have the potential to enhance public health, expand their role, provide patient-centred care, and support the national healthcare system.

The current status of health care indices and functional independence among older adults: data from HelpAge international-jordan study.

BACKGROUND: Health services should anticipate the changing pattern of illnesses associated with population aging to promote healthy aging. AIM: We aimed to evaluate health indices and chronic illnesses and their relationship with functional independence in community Syrian refugees & Jordanian elderly. METHODS: A stratified sample of 1,718 community older adults aged ≥ 60-year-old from four major Jordanian governorates was interviewed in this cross-sectional study. Katz Index of Independence in Activities of Daily Living was utilized to assess functional status. Data were analyzed using STATA 15. RESULTS: Despite the similarities in baseline function, Syrian refugees had more multimorbidities but less active health insurance, accessibility to healthcare services and availability of medications and medical devices than Jordanians. Two-thirds had multimorbidities; with heart diseases, musculoskeletal conditions, hypertension, and diabetes being the most commonly reported chronic illnesses. Females had significantly more multimorbidities, and functional dependence, yet less education, income and accessibility to healthcare services. The mean Katz Index score was 4.99 ± 1.61. Significant predictors of functional dependence included increasing age, lower level of education, and some chronic illnesses. CONCLUSION: National inclusive plans to support vulnerable older adults especially refugees and older women, provide health insurance, enhance access to health care facilities, and manage chronic medical illnesses comprehensively are urgently needed to improve independence of community-living older adults and to promote healthy aging.

Identifying Health Literacy Strengths and Needs Among Jordanian Acute Myocardial Infarction Patients.

Acute myocardial infarction is a significant health issue, particularly in Jordan where ischemic heart disease is the leading cause of death. Effective management of acute myocardial infarction is essential to mitigate its consequences. Although health literacy is crucial for the successful management of acute myocardial infarction, research about the strengths and needs of health literacy among acute myocardial infarction patients is still limited. This study was conducted to identify the health literacy strengths and needs of Jordanian acute myocardial infarction patients using cluster analysis. A cross-sectional design was used to conduct this study in a sample of acute myocardial infarction patients in Jordan (N = 114). A demographics questionnaire and the Health Literacy Questionnaire were used to collect the data. Data analysis was performed using hierarchical cluster analysis using Ward's method. Seven distinct clusters of acute myocardial infarction patients were identified, each characterized by unique health literacy profiles and sociodemographic characteristics. Cluster 7 had the highest health literacy scores across all nine Health Literacy Questionnaire scales. Sociodemographic factors such as age, education level, and gender influenced health literacy levels, with female, younger, more educated patients exhibiting higher health literacy. Through identifying the specific strengths and needs, this research provides a foundation for developing targeted health literacy interventions for acute myocardial infarction patients. Improving health literacy among acute myocardial infarction patients can enhance their ability to manage their health and potentially reduce the complications associated with acute myocardial infarction.

The strength of the Earth's magnetic field from Pre-Pottery to Pottery Neolithic, Jordan.

Constraining secular variation of the Earth's magnetic field strength in the past is fundamental to understanding short-term processes of the geodynamo. Such records also constitute a powerful and independent dating tool for archaeological sites and geological formations. In this study, we present 11 robust archaeointensity results from Pre-Pottery to Pottery Neolithic Jordan that are based on both clay and flint (chert) artifacts. Two of these results constitute the oldest archaeointensity data for the entire Levant, ancient Egypt, Turkey, and Mesopotamia, extending the archaeomagnetic reference curve for the Holocene. Virtual Axial Dipole Moments (VADMs) show that the Earth's magnetic field in the Southern Levant was weak (about two-thirds the present field) at around 7600 BCE, recovering its strength to greater than the present field around 7000 BCE, and gradually weakening again around 5200 BCE. In addition, successful results obtained from burnt flint demonstrate the potential of this very common, and yet rarely used, material in archaeomagnetic research, in particular for prehistoric periods from the first use of fire to the invention of pottery.

A coupled human-natural system analysis of freshwater security under climate and population change.

Limited water availability, population growth, and climate change have resulted in freshwater crises in many countries. Jordan's situation is emblematic, compounded by conflict-induced population shocks. Integrating knowledge across hydrology, climatology, agriculture, political science, geography, and economics, we present the Jordan Water Model, a nationwide coupled human-natural-engineered systems model that is used to evaluate Jordan's freshwater security under climate and socioeconomic changes. The complex systems model simulates the trajectory of Jordan's water system, representing dynamic interactions between a hierarchy of actors and the natural and engineered water environment. A multiagent modeling approach enables the quantification of impacts at the level of thousands of representative agents across sectors, allowing for the evaluation of both systemwide and distributional outcomes translated into a suite of water-security metrics (vulnerability, equity, shortage duration, and economic well-being). Model results indicate severe, potentially destabilizing, declines in freshwater security. Per capita water availability decreases by approximately 50% by the end of the century. Without intervening measures, >90% of the low-income household population experiences critical insecurity by the end of the century, receiving <40 L per capita per day. Widening disparity in freshwater use, lengthening shortage durations, and declining economic welfare are prevalent across narratives. To gain a foothold on its freshwater future, Jordan must enact a sweeping portfolio of ambitious interventions that include large-scale desalinization and comprehensive water sector reform, with model results revealing exponential improvements in water security through the coordination of supply- and demand-side measures.

210Po and 210Pb radioactivity levels in local and imported tobacco used in Palestine and Jordan.

This study aimed to assess the concentrations of 210Po and 210Pb in various tobacco samples from Palestine and Jordan. Cigarette smoking is recognized as a significant contributor to the radiation dose received by individuals, primarily due to the elevated levels of 210Pb and 210Po found in tobacco. The analysis revealed that the average concentrations of 210Po in locally sourced tobacco and cigarette samples in Palestine are 16.8 ± 2.3 mBq/g and 18.5 ± 2.0 mBq/g, with a total average of 17.8 ± 7.4 mBq/g (15.5 mBq/cigarette). Similarly, the average concentrations of 210Pb in these samples are 18.5 ± 2.6 mBq/g and 20.3 ± 2.2 mBq/g, with a total average of 19.6 ± 8.1 mBq/g (17.0 mBq/cigarette). In Jordan, the average concentrations of 210Po in cigarette samples and narghile tobacco are 20.1 ± 2.4 mBq/g and 18.3 ± 4.1 mBq/g, with a total average value of 19.6 ± 9.9 mBq/g (18.0 mBq/cigarette), while the average concentrations of 210Pb are 22.2 ± 2.6 mBq/g and 20.2 ± 4.5 mBq/g, with a total average value of 21.6 ± 10.8 mBq/g (19.9 mBq/cigarette). The annual effective doses resulting from inhalation were calculated for smokers of these samples. The findings revealed that the levels of 210Po and 210Pb radioactivity in certain investigated samples exceeded the results of studies in many countries of the world. The associated effective doses per year from smoking for all brands products in Palestine range from 34.7 µSv/y to 186.5 µSv/y with an average of 109.5 µSv/y, while in Jordan 54.5 µSv/y to 289.1 µSv/y with an average of 130.9 µSv/y.

Preventing violence and enhancing mental health among clients of an invitro fertilization clinic in Jordan: results of a pre/post pilot test of the use of cognitive behavioral therapy.

INTRODUCTION: Infertility increases women's risk of intimate partner violence (IPV). Cognitive behavioral therapy (CBT) is commonly used to treat mental health problems among fertility treatment seeking patients. CBT has not been tested for its potential to reduce IPV in this population. We pilot test the use of CBT to prevent IPV and improve patients' mental health in a fertility clinic in Jordan. METHODS: Of 38 eligible fertility-treatment seeking couples, 16 consented and underwent up to 11 CBT sessions (average = 9) over 3 months. Interviews at baseline and 16 weeks post intervention (endline) assessed IPV, quality of life, social support, coping, and fear of spouse. Wilcoxon signed-rank and McNemar's tests were used to assess change in outcomes. RESULTS: At baseline, women's rates of IPV, depression, and anxiety were 75%, 87.5%, and 75% respectively, whereas men's rates of depression and anxiety were each 80%. Average baseline post-traumatic stress disorder (PTSD) symptoms for men and women were 3.3 and 2.7 respectively out of 5. IPV decreased 25% after treatment, and women reported less spousal fear. For both men and women, depression, anxiety, and PTSD symptoms decreased and social support and fertility quality of life improved. CONCLUSION: Psychosocial support should be standard of care for the treatment of infertility given the burden of mental health problems and IPV and the utility of CBT in this patient population. Co-design with couples is needed to identify strategies to bolster participation along with population-based interventions to combat the stigma of infertility and mental health service use and enhance women's status.
