    Abstract The aim of this search was to understand the effect of humic acid on soil properties and the growth and salinity tolerance of maize irrigated with saline water. The experiment was conducted in the Sabboura Research Station, Syria in 2019–2020. As treatments, humic acid was added to the soil at concentrations of 0, 1, and 2 g/L·m 2 , and the crop was irrigated using saline water with 0.5, 2, 4, and 6 ds/m salinity, measured by electrical conductivity (EC). The results showed that treatment with 2 ds/m irrigation water salinity and 2 g/L·m 2 of humic acid achieved the highest fresh biomass production and plant height compared to the control and other treatments, while 4 ds/m irrigation water salinity and 0 g/L·m 2 of humic acid gave the highest productivity measured by dry mass. In addition, the pH value increased up to 9.15 for the treatment with 6 ds/m irrigation water salinity and 2 g/L·m 2 of humic acid, while the EC values increased with an increase in salinity in the irrigation water, and the highest value (2.59 ds/m) occurred in the treatment with 6 ds/m irrigation water salinity and 2 g/L·m 2 of humic acid. The use of highly saline irrigation water (6 ds/m) led to an increase in EC and caused a noticeable decrease in plant height and fresh biomass accumulation in all treatments, indicating that maize cannot tolerate more than 6 ds/m irrigation water salinity.

    Abstract Vibriosis disease is a major threat to the aquaculture industry caused by Vibrio spp. that are often resistant to antibiotics. Alternative controlling measures such as bacteriocins could be effective due to their narrow-spectrum activity. Hence, this systematic literature review (SLR) was carried out to review the feasibility of Vibrio spp. and their vibriocins to be used as a vibriosis control measure in aquaculture. A literature search using the web of science (WOS) and SCOPUS databases resulted in 42 unique articles which were reviewed. The results showed that Vibrio spp. could be used as a probiotic to control vibriosis, but not recommended due to their opportunistic nature and pathogenesis. Vibriocin showed narrow-spectrum activity against Vibrio spp. including highly pathogenic strains such as V. alginolyticus, V. harveyi, and V. parahaemolyticus. This supported this review's hypothesis of using vibriocin as a targeted vibriosis control measure. Vibrio cholerae was the most studied and showed the highest inhibition range, inhibiting 13 different vibrio and non-vibrio species. Various innovations were reported in the field and vibriocins can now be produced on large scales using whole-cell culture. Vibriocins were structurally diverse, large molecular weight, and relatively heat stable. These vibriocins mainly inhibited the cell wall but could have other novel mechanisms. These properties could affect the extraction process as well as applications in aquaculture, hence, should be considered in future research.

    Abstract Limited data exists on the mental health of children in the United Arab Emirates (UAE). This study aimed to fill this gap by examining the prevalence of anxiety, depression, and risk for Post-Traumatic Stress Disorder (PTSD) among school students in post-lockdown of the COVID-19 pandemic. A sample of 3,745 school students participated, responding to standardized tests (Mood and Feeling Questionnaire-Child Self-Report, Screen for Child Anxiety Related Disorders-Child Version, and Children's Revised Impact of Event Scale-8). Findings showed that the risk for PTSD was the most prevalent (40.6%), followed by symptoms of anxiety (23.3%), and depression (17.1%). For gender differences, symptoms of the three conditions (depression, anxiety, and PTSD) were higher in female students (9.2%) compared to male peers (7.7%) (p = 0.09). Moreover, symptoms of depression and anxiety were found to be higher among late adolescents (p<0.05). Further analysis revealed that having medical problems was a positive predictor for anxiety (OR = 2.0, p<0.01) and risk for PTSD (OR = 1.3, p = 0.002); similarly, witnessing the death of a close family member due to COVID-19 (OR for depression, anxiety, and PTSD = 1.7, p<0.01) were positive predictors associated with PTDS, depression, and anxiety. The study concluded that post COVID-19 lockdown, symptoms of anxiety, depression, and risk for PTSD were found to be prevalent among school students in the UAE. Researchers put forward recommendations on the initiation of a national school mental health screening program, the provision of follow-up services for vulnerable students, and the integration of a mental health support system in the disaster preparedness plans.

    Abstract Yemen has witnessed a significant rise in AIDS-related deaths because of very poor access to antiretroviral treatment and because of the current war situation. This study aimed to assess the attributes of human immunodeficiency virus (HIV) reporting form, including usefulness, simplicity, flexibility, and acceptability, which is used for reporting HIV cases in Sana'a, Yemen. A descriptive cross-sectional study was conducted among 311 physicians from public and private health facilities in Sana'a city. Physicians were interviewed using a structured questionnaire to assess the form's attributes. The mean score was calculated for each attribute and converted to percentages which were interpreted as very poor, poor, average, good, and excellent. The usefulness overall score was 76%, indicating average usefulness. Of the total participants, 283 (91%) and 304 (97.7%) stated that the form is clear and easy to fill, respectively. More than two-thirds (68.5%) of physicians stated that the form ensures the privacy of the customer's identity. The simplicity attribute score was 74.5%, indicating average simplicity. The overall flexibility was 69.2%, indicating average flexibility. A total of 175 (56%) physicians indicated that they are completely satisfied with the reporting form. The acceptability score was 75.2%, indicating that the HIV/AIDS reporting form of HIV is average in acceptability. The HIV/AIDS reporting form in Yemen was scored average in usefulness, simplicity, flexibility, and acceptability. Training health workers on using the reporting form would improve the performance of HIV/AIDS reporting. Moreover, the reporting form could be adapted to be integrated with other surveillance such as tuberculosis surveillance.

    Abstract Context Solitary rectal ulcer (SRU) is a disease with many challenging issues. There are several controversies about the basic pathophysiology of this disease. Despite its name, “solitary rectal ulcer”, more than a quarter of patients do not show any ulcer in colonoscopy. Instead, many patients show multiple polypoid lesions. Some previous reports have suggested calling this disease “rectal mucosal prolapse” instead of SRU, however, most of the patients do not have mucosal prolapse. In addition, colonoscopic findings can be very similar to cancer and inflammatory bowel disease, so without histologic evaluation, accurate diagnosis is not always possible. In patients with SRU, sometimes the rectal mucosa is so fibrotic that mucosal biopsy is inadequate, and even a pathologist cannot diagnose the characteristic histologic findings. There are various therapeutic approaches for the treatment of SRU, both surgical and nonsurgical, all of which are not optimal, and recurrence rates are still high with many patients experiencing complications even after surgery, resection and rectopexy. Evidence Acquisition Although this disease is not uncommon in Iran, there are very few studies from Iran, therefore, in this review we will describe our experience with patients with SRU in affiliated hospitals of Shiraz University of Medical Sciences. We will also review previously published articles about SRU that are indexed in PubMed and Google scholar, emphasizing the challenging issues. Results SRU is not an uncommon disease in Iran, however the number of published articles about it, is very low. Multicentric studies are necessary to find out the definite reason of this issue. Conclusions There are still many conflicting controversies about the etiology, pathogenesis, diagnosis and also treatment of SRU, which need further investigation and longer follow up of the patient in each therapeutic approach to be better understood.

    Abstract Purpose of review: Current oncologic treatments have shown improvement in overall survival in cancer patients. However, the cardiac toxicities of cancer therapeutics, particularly chemotherapy, targeted therapy and immunotherapy can have life-threatening side effects.
    Recent findings: A MEDLINE search for cardiovascular toxicities associated with Federal Drug Administration (FDA)-approved cancer treatments including chemotherapy, targeted therapy and immunotherapy was performed. We included comprehensive articles and research articles establishing the incidence, diagnosis, monitoring and management of cardiovascular toxicities related to cancer treatments until January 2019.This review highlights the mechanisms and epidemiology of cardiotoxicity associated with some cancer treatments. The most common cardiovascular side-effects are discussed at an introductory level with emphasis on those related with the development of heart failure.
    Summary: Cardiovascular side effects of cancer treatments are common and might affect the survival in cancer patients. Recognition and management of these side effects require understanding of their mechanisms and their clinical manifestations. A multidisciplinary approach with understanding of both the cardiovascular and oncologic risks is necessary in order to provide well tolerated and effective cardio-oncology care.

    Abstract Human amniotic fluid cells have been used traditionally as a diagnostic tool for genetic anomalies. More recently it has been recognized that amniotic fluid contains populations of stem cells. Mesenchymal stem cells (AFMSC) were first to be described. These cells are able to differentiate towards mesodermal lineages. More recently cells with broader potential, defined as amniotic fluid stem cells (AFSC), were also isolated. They have intermediate characteristics between embryonic and adult stem cells and are able to differentiate into lineages representative of all three germ layers but unlike ES cells they do not form tumours in vivo. Furthermore, AFSC have been reverted to functional pluripotency in a transgene-free approach using an epigenetics modifier. These characteristics, together with absence of ethical issues concerning their employment, have made stem cells from amniotic fluid a promising candidate for cell therapy and tissue engineering.
