MPIG6B Gene-Related Myelofibrosis: A Rare Inherited Disease That Is Frequently Described in Arab Population.

The megakaryocyte and platelet inhibitory receptor gene G6P (MPIG6B) is located on chromosome 6p21.33. It encodes G6b-B; an inhibitory receptor expressed on the surface of platelets. It regulates platelets production, aggregation, and activation. We describe a case of a 31-year-old man who presented with a long history of thrombocytopenia, anemia, and hepatosplenomegaly. The patient received multiple blood transfusions and his clinical course was stable. A bone marrow biopsy showed morphologic features similar to primary myelofibrosis. Whole exome sequencing study was performed and revealed homozygous pathogenic mutation in exon 2 of MPIG6B gene (c.324C > A, p.Cys108Ter) that is the second reported case in literature. In this report, we describe the main clinical and pathologic features of this disease and review the literature of previously documented cases.

Pancytopenia with aplastic anemia in systemic lupus erythematosus: case series and literature review.

Aplastic anemia (AA) is a rare, potentially catastrophic hematopoiesis failure manifested by pancytopenia and bone marrow aplasia. AA occurrence in Systemic Lupus Erythematosus (SLE) patients is extremely rare. The diagnosis may be delayed due to other possible pancytopenia etiologies. Confirmation of peripheral cytopenias diagnosis necessitates a bone marrow aspiration. The management of AA is challenging, and the literature reported using glucocorticoids, danazol, plasmapheresis, cyclophosphamide, intravenous immunoglobulin, and cyclosporine. We report two cases of SLE patients who presented with pancytopenia, with bone marrow biopsy confirmed AA. One case was treated with cyclophosphamide but unfortunately succumbed to Acute Respiratory Distress Syndrome (ARDS), while the other case was managed with rituximab with a good response. Interestingly, both patients were on azathioprine before the diagnosis of AA. A comprehensive search for reported cases of AA in PubMed, Scopus, and the Directory of Open Access Journals databases was performed to enhance the understanding of the diagnostic and management challenges associated with AA in SLE, facilitating ongoing exploration and research in this field. The decision to do a BM aspiration and biopsy is recommended for SLE patients with an abrupt decline in blood counts and previously stable blood counts.

Genetic predisposition to early mycosis fungoides: investigating genetic polymorphisms in tissue-resident memory T-cell genes.

OBJECTIVES: Mycosis fungoides (MF) is the most common cutaneous T-cell lymphoma; it arises from tissue-resident memory T-cells (TRM). In the present study, we investigated potential functional genetic variations that may predispose MF development. METHODS: A case-control study was conducted using whole-exome sequencing, with a focus on genes that are essential to TRM function. RESULTS: We included 21 patients and 19 healthy subjects in the study. Single nucleotide polymorphisms in the following genes were significantly more common in patients than in healthy subjects: GZMB, HLA-DRB1, CD103, and NOTCH1. Moreover, the number of patients carrying single nucleotide polymorphisms in LAG3, NR4A2, and CD26L was significantly greater in the patient group than in the control group. CONCLUSIONS: The presence of genetic variations in one or more TRM functional gene may predispose patients to develop MF. Further studies involving a larger patient population and a comparative analysis of protein expression will be necessary to validate these findings.

Disparities in Obstetric, Neonatal, and Birth Outcomes Among Syrian Women Refugees and Jordanian Women.

Objectives: To compare obstetric and neonatal characteristics and birth outcomes between Syrian refugees and native women in Jordan. Methods: We used the Jordan Stillbirths and Neonatal Deaths Surveillance System to extract sociodemographic and obstetric characteristics of the mothers and birth characteristics of newborns. Multivariate analysis was used to compare the characteristics of 26,139 Jordanian women (27,468 births) and 3,453 Syrian women refugees (3,638 births) who gave birth in five referral hospitals (May 2019 and December 2020). Results: The proportions of low birthweight (14.1% vs. 11.8%, p < 0.001) and small for gestational age (12.0% vs. 10.0%, p < 0.001) newborns were significantly higher for those born to Syrian women compared to those born to Jordanian women. The stillbirth rate (15.1 vs. 9.9 per 1,000 births, p = 0.003), the neonatal death rate (21.2 vs. 13.2 per 1,000 live births, p < 0.001), and perinatal death rate (21.2 vs. 13.2 per 1,000 births, p < 0.001) were significantly higher for the Syrian births. After adjusting for sociodemographic and obstetric characteristics of women, only perinatal death was statistically significantly higher among Syrian babies compared to Jordanian babies (OR = 1.3, 95% CI: 1.1-1.7, p = 0.035). Conclusion: Syrian refugee mothers had a significantly higher risk of adverse obstetric and neonatal outcomes including higher rate of perinatal death compared to Jordanian women.

Identifying psychosocial problems, needs, and coping mechanisms of adolescent Syrian refugees in Jordan.

Background: Refugees who have fled war zones are at a heightened risk of psychosocial problems that can impact their ability to function in day-to-day life and place a significant burden on the family structure. This study aimed to assess the psychosocial problems and needs and coping mechanisms of Adolescent Syrian refugees in Jordan. Methods: Between October and December 2018, we conducted a qualitative study using semi-structured interviews with a sample of key and individual informants. Our sample included 20 primary healthcare professionals, 20 schoolteachers, 20 Syrian parents, and 20 adolescents aged 12-17 years. All interviews were transcribed verbatim, and we utilized thematic analysis to group, categorize, and analyze the original Arabic language transcripts. To ensure thorough analysis, we adopted a bottom-up inductive approach that covered the six-phase iterative process proposed by Braun and Clarke. Results: The main psychosocial problems encountered by Syrian adolescents included stress, depression, loneliness, lack of a sense of security, isolation, aggressiveness, fear of war, and family disintegration. Almost all schoolteachers reported that they observed that Jordanian adolescents are more settled, self-confident, and financially stable relative to their Syrian peers. The Jordanian government and community were praised for their support, including education, recreational centers, health services, and awareness campaigns. Going to school, praying and reading the Holy Quran, listening to music, and talking to friends and engaging with them were reported as the main coping mechanisms. The majority of respondents said that more services are still needed for adolescents, including more places for entertainment, psychosocial support and psychological counseling, medical care, job creation, and providing health insurance. Conclusion: Syrian refugees are aware of the psychological aspects of their situation, but they are not always able to access clinic-based humanitarian assistance for mental health and psychosocial support. Stakeholders must interact with refugees to learn about their needs and develop services that are appropriate for their culture.

The Health Literacy of Retinol Cream Usage Among Female Students in the Faculty of Artificial Intelligence at Al-Balqa Applied University.

INTRODUCTION: Considering people's tendency to self-treatment, efforts to address the broad aspects of health literacy are extremely important. The study aimed to find out the level of health literacy related to the use of retinol creams among female undergraduate students of the Faculty of Artificial Intelligence at Al-Balqa Applied University. METHODS: This study adopted an analytical descriptive research methodology by designing and applying a questionnaire tool. The questionnaire consisted, after arbitration and testing its validity and stability, of 15 items. Each item represents one of the indicators for measuring the level of health literacy about the use of retinol creams. The sample of the study was a random sample of female students in the Faculty of Artificial Intelligence at Al-Balqa Applied University. RESULTS: A total of 221 undergraduate female students were enrolled in the study. The most important results were that the arithmetic mean for estimating the level of health culture among female students in the study on the use of retinol creams was 3.117 out of 5, with a relative weight percentage of 62.3% and an average total score on the general level of indicators of total health culture. CONCLUSION: This study provided insights into the health literacy related to the use of retinol creams among female students. While the students demonstrated a high level of health education in some aspects, there were areas where their knowledge and practices could be improved. These findings can contribute to the development of educational programs and interventions aimed at promoting the safe and informed use of retinol creams among university students.

The level and distribution of selected organochlorine pesticides in water of River Satluj Pakistan.

The study was aimed to identify different environmental factors (selected organochlorine pesticides) affecting the river water of Satluj. River Sutlej is about 1400 kilometers long and its water is extensively used for irrigation in Punjab, located both in India and Pakistan, which was also a reason of dispute between both countries for its water share. The study area was divided into four zones, Sulemanki Zone, Islam Zone, Mailsi Syphone Zone and Panjnad Zone. Liquid Liquid Extraction (LLE) technique was used for the collected water samples followed by high performance liquid chromatography (HPLC) UV-Visible detector The current finding revealed that aldrin was not detected during summer period in water samples of SZ-1 (Sulemanki Barrage), SZ-2 and SZ-3 (Maisli Siphon) of the study area. Lindane and DDE were found more in the samples of sediments from the study area at SZ-4 ranging from 2.238-8.226 ppb and 4.234-6.876 ppb, respectively. Heaptachlor (in sediments) was found to be0.032-234 ppb only at SZ-4.Endosulfan concentrations in water (winter) at SZ-3 was 0.06 ppb and at SZ-4,it was 0.05 ppb; dieldrin in water (winter) at SZ-4 was 0.0314 ppb and heptachlor was detected at SZ-1 (0.0315 ppb) and SZ-2 (0.0310 ppb) in water during winter season, were reaching to the Maximum Concentrations Limits (MCL), while all other residues investigated were found below the MCLin all the compartments of the study area set by various agencies like WHO/FAO- Codex Alimenterious. Present findings revealed that although the organochlorine pesticides are banned for agricultural use in many countries, including Pakistan, their presence in various samples might be due to illegal use of these pesticides in the study area and its neighboring regions. The overall study area comprises of mainly urban, suburban and agricultural land being the largest cotton growing area of the country. There is a need to take serious steps to minimize water pollution caused by pesticides to achieve a healthy lifestyle.

Rice anther tapetum: a vital reproductive cell layer for sporopollenin biosynthesis and pollen exine patterning.

The tapetum is the innermost layer of the four layers of the rice anther that provides protection and essential nutrients to pollen grain development and delivers precursors for pollen exine formation. The tapetum has a key role in the normal development of pollen grains and tapetal programmed cell death (PCD) that is linked with sporopollenin biosynthesis and transport. Recently, many genes have been identified that are involved in tapetum formation in rice and Arabidopsis. Genetic mutation in PCD-associated genes could affect normal tapetal PCD, which finally leads to aborted pollen grains and male sterility in rice. In this review, we discuss the most recent research on rice tapetum development, including genomic, transcriptomic and proteomic studies. Furthermore, tapetal PCD, sporopollenin biosynthesis, ROS activity for tapetum function and its role in male reproductive development are discussed in detail. This will improve our understanding of the role of the tapetum in male fertility using rice as a model system, and provide information that can be applied in rice hybridization and that of other major crops.

PAX5 and TDT-Negative B-Acute Lymphoblastic Leukemia with Unusual Genetic Mutations: A Case Report.

B-acute lymphoblastic leukemia (B-ALL) is commonly encountered in clinical practice. Patients present with increased percentage of lymphoblasts in bone marrow and/or peripheral blood. Immunophenotypic study by flow cytometry or immunohistochemistry is essential to establish the diagnosis. Paired box-5 (PAX5) is a B cell lineage protein and terminal deoxynucleotidyl transferase (TDT) is an immature marker, both of which are routinely tested in the pathologic workup of acute leukemia. In this report, we describe a case of B-ALL in a 37-year-old woman in which both PAX5 and TDT were negative. Next-generation sequencing test detected mutations in DNA methyltransferase 3 α and Fms related receptor tyrosine kinase 3 genes, which are frequently mutated in acute myeloid leukemia rather than B-ALL. The constellation of these rare findings in a single case signifies the importance of examining a wide panel of markers when the diagnosis of ALL is suspected.

Presence of selected organochlorine pesticides (OCPs) in sediments and biota of River Satluj, Pakistan: first report.

In the developed countries, the use of OCPs (organochlorine pesticides) has been banned. However, in South Asia several of them are still in use. In Pakistan and India a constant addition of OCPs into the atmosphere has been indicated by various researchers. In this study levels of selected organochlorine pesticide residues were assessed in sediment and biota collected from four (4) water reservoirs (3 Barrages & 1 Siphon) on the River Satluj Pakistan, along 231 miles (372 km) of River stretch which was further divided into 12 sampling sites. It was aimed to find out the levels of organochlorine pesticide (OCPs) residues in sediments and from selected fish species (Labeo rohita, Wallagu attu, Cyprinus carpio) of the River Satluj Pakistan. The Organochlorine residues (seven pesticides) present in samples of sediments and biota were investigated through multi residue method, using Gas Chromatograph (GC-ECD).In the current study, the concentration of DDT, was investigated in Wallago attu (0.786-3.987 ppb), Labeo rohita (0.779-4.355 ppb) and Cyprinus carpio (1.234-5.654 ppb). DDE was also found in Cyprinus carpio (1.244-6.322 ppb), Wallag attu (0.877-4.221 ppb) and Labeo rohita (2.112-5.897 ppb). Aldrin was not observed in Labeo rohita and Wallago attu. Currently, lindane and DDE was found predominately high in the sediments of study area at SZ-4 (Panjnad Barrage) ranging (2.238-8.226 ppb) and (4.234-6.876 ppb), respectively. Heaptachlor was found only at SZ-4 (Panjnad Barrage) from the sediments with concentration ranging (0.032-234 ppb). In short all other residues investigated were found below the MCL (maximum concentration level) in all the compartments of the study area set by various agencies like WHO/FAO- Codex Alimenterious.

Relationship of stigmatization and social support with depression and anxiety among cognitively intact older adults.

Aims and objectives: This study aimed to assess depression and anxiety symptoms among older adult residents of long-term care facilities (LTCFs) in Jordan and to examine the relationships between stigmatization and social support with depression and anxiety. Methods: Data was collected between December 2019 and March 2020 using a cross-sectional design. A total of 90 LTCF residents responded to measures of cognition, anxiety, depression, stigmatization, and social support. Descriptive statistics and multiple regression analyses were used in this study. Results: The average scores of depression and anxiety were high among the participants, with 81.1% of the participants found to be at risk of developing clinical depression. Stigmatization was positively correlated with depression and anxiety, whereas social support was negatively correlated with depression. Stigmatization was a significant predictor of both anxiety and depression scores (ß = .19, p = .03; ß = .32, p = .001, respectively). Conclusions: Older adults residing in LTCFs in Jordan suffer from many psychological distress symptoms, which place them at risk of serious mental problems. Reducing stigmatization would improve the psychological well-being of LTCF residents. Relevance to clinical practice: Caregivers working at LTCFs should be aware that with the longer stay, older adult residents are expected to complain of psychological distress symptoms. Thus, frequent assessment of the residents is highly recommended. In addition, caregivers should provide the residents with appropriate social support to mitigate the negative impact of a lengthy stay.

Knowledge, attitude, practice and perceived barriers towards smoking cessation services among community pharmacists.

Introduction: With more than one billion current smokers, 80% of them living in low and middle-income countries, tobacco smoking is considered a global public health problem. Jordan has one of the highest estimate rates of tobacco use in the region and world. Still, tobacco use interventions, that could significantly reduce the number of smoking-related diseases and reduce health care costs, are scarce. While such interventions could be carried out by community pharmacists, given their unique position to counsel patients and provide effective cessation interventions, the role of community pharmacists in tobacco control services in Jordan has never been fully investigated. Objective: This study aimed at assessing the community pharmacists' knowledge, attitudes, and practice towards smoking cessation and identifying their perceived barriers for smoking cessation counselling utilizing a sample of community pharmacists in Northern Jordan. Method: A cross-sectional study was conducted among community pharmacies in Irbid city, North of Jordan, between April and August 2018. A random sample of 95 pharmacies was selected using the multistage random sampling technique. A structured English questionnaire, consisting of 5 parts, was used. The Survey assessed pharmacists' socio-demographics, knowledge, attitude, practice and perceived barriers related to tobacco use cessation services. Results: One hundred and fifty pharmacists completed the survey. Their mean age was 30.71±10.10 years. The mean of pharmacists' knowledge score was 3.74±0.38, while their positive and negative attitude were 3.87±0.43 and 3.18±0.66 respectively. Pharmacists' mean smoking cessation practice was 2.01+0.64. Barriers to providing cessation interventions included the lack of training on nicotine replacement therapy products (86%), the lack of smoking cessation programs (84%) and low demands from smokers (83.3%). Conclusion: While knowledge related to tobacco use cessation services among the community pharmacists was sub-optimal, a good positive attitude and a low practice levels were observed. The lack of educational materials, low patients' demand, knowledge deficits, low training and the lack of cessation programs have been identified as barriers hindering the provision of smoking cessation services. Furthermore, the study identified factors that will increase community pharmacists' participation in smoking cessation, help in raising pharmacists' awareness of smoking as a public health problem and the importance of their role.

Parental Willingness to Vaccinate Their Children Against SARS-CoV-2 in Jordan: An Explanatory Cross-Sectional Study.

Background: Successful control of the COVID-19 pandemic is largely dependent on vaccine administration to epidemiologically influential groups, including children. Considering that pediatric population comprises a significant portion on the population in developing countries, and their risk of infection and spreading the disease has been underestimated, it is crucial to investigate parental willingness to administer SARS-CoV-2 vaccine to their children between 5 and 11 years old. This study investigates the prevalence and determinants of parental willingness towards vaccinating their children (5-12 years old) against COVID-19 in a developing country setting, Jordan. Methods: A cross-sectional study, conducted between October and November 2021, utilized online Google Forms to collect data on parents' background characteristics, willingness to vaccinate their children, SARS-CoV-2, infection and vaccine, risk perception, and factors affecting decision to vaccinate. Results: A total of 564 parents completed the questionnaire; 82.8% were mothers, 85.3% were 30 years of age or older, and 75.9% had bachelor's degrees or higher. Only 25.4% of parents reported willingness to vaccinate their 5-12 years old children against SARS-CoV-2. Lower parental age, higher income, and having health insurance coverage increased parental willingness. Among participants vaccinated against COVID-19, only 29.0% were willing to vaccinate their children. Healthcare providers' trust and vaccine recommendations by pediatricians increased parental willingness. COVID-19 risk perception seems to have negative effects on parental willingness. Conclusion: A significant proportion of parents in Jordan indicated hesitancy towards administering COVID-19 vaccine for their children. Concerns about vaccine safety and trust in the healthcare system appear to be the most important predictors of parents' hesitancy. Effective vaccine campaigns should focus on risk perception and communication and should consider parental socio-demographic characteristics.

Programmed Death Ligand-1 is Frequently Expressed in Primary Acute Myeloid Leukemia and B-Acute Lymphoblastic Leukemia.

BACKGROUND: The introduction of checkpoint inhibitors in solid cancer therapy showed successful results. The role of Programmed Death-1/Programmed Death-Ligand 1 (PD1/PD-L1) in hematologic malignancies is currently being investigated and clinical trials are ongoing. Preliminary findings showed conflicting results. In this study, we examined the degree of PD-L1 and PD-L2 expression in primary acute leukemia patients. METHODS: Flow cytometry expression of PD-L1 and PD-L2 was evaluated in de novo acute leukemia in the collaborating institutions between 2018 - 2020. RESULTS: One hundred forty patients were identified. PD-L1 was positive in 34/70 (49%) of AML, 25/50 (50%) of B-ALL, and none (0/20) of T-ALL patients. In contrast, PD-L2 was solely expressed in eight (19%) AML patients. The expression of PD-L1 showed statistically significant correlation with the type of acute leukemia (AML and B-ALL > T-ALL, p < 0.001) and with age group (adults > children, p = 0.048), but not with blast count, immunophenotype or cytogenetic mutations. The positivity for PD-L1 was associated with worse overall survival in AML, but not in B-ALL. CONCLUSIONS: The expression of PD-L1 is common among newly diagnosed AML and B-ALL patients and is not restricted to relapsed cases as previously described. PD-L2 is less commonly expressed and is accompanied by PD-L1 expression. Positive PD-L1 patients may benefit from treatment with immune checkpoint inhibitors, especially in AML. Further studies are recommended.

The Expression of the Senescence-Associated Biomarker Lamin B1 in Human Breast Cancer.

Senescence is a major response to cancer chemotherapy and has been linked to unfavorable therapy outcomes. Lamin B1 is a component of the nuclear lamina that plays a pivotal role in chromatin stability. Downregulation of lamin B1 represents an established biomarker for cellular senescence. However, the protein expression level of lamin B1 in malignant tissue, particularly of the breast, has not been previously described. In this work, we investigated lamin B1 protein expression in normal breast epithelium, malignant breast tissue (including adjacent non-malignant tissue) and in malignant tissue exposed to neoadjuvant chemotherapy (NAC) using immunohistochemistry (IHC) in three patient groups (n = 15, n = 87, and n = 43, respectively). Our results indicate that lamin B1 mean positive expression was 93% in normal breast epithelium and 88% in malignant breast cells, but significantly decreased (mean: 55%, p < 0.001) in malignant breast tissue after exposure to NAC, suggestive of senescence induction. No significant association between lamin B1 expression and other clinicopathological characteristics or survival of breast cancer patients was recorded. To our knowledge, this is the first report that established the baseline protein expression level of lamin B1 in normal and malignant breast tissue, and its reduction following exposure to chemotherapy. In conclusion, lamin B1 downregulation can be used reliably as a component of multiple biomarker batteries to identify therapy-induced senescence (TIS) in clinical cancer.

Increased incidence of musculoskeletal pain in medical students during distance learning necessitated by the COVID-19 pandemic.

As a consequence of lockdown during the COVID-19 pandemic, the education system has changed globally. Face to face education has been replaced by distance learning. The aim of the present study was to find the prevalence of musculoskeletal pain and syndromes among medical students during distance learning and to investigate the correlations of musculoskeletal pain with different causal factors. A total of 282 students completed an online questionnaire that measured time spent on digital devices, type of physical activity, time spent sitting, number of walking days/week, ergonomics, and postural habits. Some of these measurements were compared between periods before and during the pandemic. Because of distance learning, time spent on digital devices and total time spent sitting increased significantly from before to during the pandemic (p < 0.001); students' daily physical activities and the number of days per week with at least 10 min of walking decreased significantly (p < 0.001). Most of the students (75.9%) experienced at least one type of musculoskeletal pain, predominately shoulder and neck pain (65%). There was a very significant positive correlation between musculoskeletal pain and postural habits (p < 0.0001). This study suggested that postural habits while sitting have a profoundly negative effect on the musculoskeletal system and are factors in the causation of musculoskeletal pain.

Live in Front of Students Teaching Sessions (LISTS): a Novel Learning Experience from Jordan During the COVID-19 Pandemic.

Objective: The COVID-19 pandemic uncovered innovative approaches in medical education. Modifications are needed to overcome the drawbacks of pure online teaching. Our study aimed at testing a hybrid method of live online practical anatomy sessions in which an element of face-to-face teacher-student interaction is maintained. Methods: We performed an experiment with a one-group design in which medical and medical laboratory sciences students were taught different practical anatomy topics using either purely online or live in front of students teaching sessions (LISTS). Students' performance and perceptions were quantitatively assessed. Results: For 108 medical laboratory sciences students, the mean quiz scores were significantly higher for the topics taught by the LISTS approach (p = 0.025). For two groups of 13 and 17 medical students, the performance in exams was significantly higher for the topics taught using the LISTS method (p = 0.000 and 0.011, respectively) with large effect sizes. Students' perceptions of preference, enjoyment, and satisfaction were all in favor of LISTS. Conclusions: Our results confirmed that keeping at least a minimum of interaction between the teacher and students can have a significant improvement in the performance and engagement in practical anatomy sessions for health professionals. The results indicate that the extra effort of LISTS was worth it.

Immunohistochemical Expression Patterns of CD45RO, p105/p50, JAK3, TOX, and IL-17 in Early-Stage Mycosis Fungoides.

The morphologic changes in early-stage mycosis fungoides (MF) might overlap with benign inflammatory dermatitis (BID). Previous studies have described altered expression patterns of several proteins in MF, but their diagnostic significance is uncertain. This study aims at examining the frequency of expression of CD45RO, NFkB-p105/p50, JAK3, TOX, and IL-17 proteins by immunohistochemistry. The cohorts included 21 patients of early-stage MF and 19 with benign BID as a control group. CD45RO was positive in all patients of MF and BID. NFkB-p105/p50 showed normal cytoplasmic staining, indicating an inactive status in all patients of both groups. JAK3 was positive in 3 (14%) MF and in 17 (89%) BID patients (p = 0.003). TOX was expressed in 19 (90%) and 13 (68%) patients of MF and BID, respectively (p = 0.120). IL-17 was detected in 13 (62%) MF and in 7 (37%) BID patients (p = 0.056). Co-expression of TOX and IL-17 was seen in 11 (52%) MF patients but in only 3 (16%) BID patients, which was statistically significant (p = 0.021). We conclude that a double expression of TOX and IL-17 may support the diagnosis of MF in the right clinicopathologic setting, while none of the immunohistochemical stains alone provided a significant discrimination between MF and BID.
