BACKGROUND: Iron overload is a risk factor affecting all patients with thalassemia intermedia (TI). We aimed to determine whether there is a relationship of serum ferritin (SF) and alanine aminotransferase (ALT) with liver iron concentration (LIC) determined by R2 magnetic resonance imaging (R2-MRI), to estimate the most relevant degree of iron overload and best time to chelate in patients with TI. METHODS: In this cross-sectional study, 119 patients with TI (mean age years) were randomly selected and compared with 120 patients who had a diagnosis of thalassemia major (TM). Correlations of LIC, as determined by R2-MRI, with SF and ALT levels, were assessed in all participants. A P-value < 0.05 was considered statistically significant. RESULTS: SF and LIC levels were lower in patients with TI than in those with TM; only ferritin values were significant. We found a statistically significant relationship between SF and LIC, with cut-off estimates of SF in patients with TI who had splenectomy and those who entered puberty spontaneously (916 and 940 ng/mL, respectively) with LIC >5 mg Fe/g dry weight (P < 0.0001). A significant relationship was also found for patients with TI who had elevated ALT level (63.5 U/L), of 3.15 times the upper normal laboratory limit, using a cut-off for LIC ≥5 mg Fe/g dry weight. CONCLUSION: We determined the cut-off values for ALT and SF indicating the best time to start iron chelation therapy in patients with TI, and found significant correlations among iron overload, SF, and ALT.

Exploring the unknown is one of the key factors that lead to great discoveries in mankind history.With the advances in medicine and the development of new approaches towards patient care, like next-generation sequencing and patient-centered care, the need for treatments tailored to patient through personalized medicine has become more compelling. Theranostics has been introduced as a combination of a diagnostic tool and a therapeutic tool on the same vector for a specific disease, to facilitate personalized medicine. Nuclear medicine has shown the capability of providing a strong platform for this new approach through its arms, molecular imaging, and targeted molecular therapies. Though the prototype of theranostics has been practiced in Jordan since decades in the field of diagnosis and treatment of well-differentiated thyroid cancer, recently, the King Hussein Cancer Center (KHCC), a leading and comprehensive cancer center in Jordan and in the Middle East, has leaped forward to introduce the new approaches of theranostics through the nuclear medicine applications. This paper sheds the light on the most important aspects of this new theranostics practice in Jordan such as peptide receptor radionuclide therapy (PRRT) and prostate-specific membrane antigen (PSMA)–based theranostics.

PURPOSE: The quality assurance (QA) chart rounds are multidisciplinary meetings to review radiation therapy (RT) treatment plans. This study focus on describing the changes in RT management based on QA round reviews in a single institution. MATERIALS AND METHODS: After 9 full years of implementation, a retrospective review of all patients whose charts passed through departmental QA chart rounds from 2007 to 2015. The reviewed cases were presented for RT plan review; subcategorized based on decision in QA rounds into: approved, minor modifications or major modifications. Major modification defined as any substantial change which required patient re-simulation orre-planning prior to commencement of RT. Minor modification included treatment plan changes which didn’t necessarily require RT re-planning. RESULTS: Overall 7,149 RT treatment plans for different anatomical sites were reviewed at QA rounds. From these treatment plans, 6,654 (93%) were approved, 144 (2%) required minor modifications, while 351 (5%) required major modifications. Major modification included changes in: selected RT dose (96/351, 27%), target volume definition (127/351, 36%), organs-at-risk contouring (10/351, 3%), dose volume objectives/constraints criteria (90/351, 26%), and intent of treatment (28/351, 8%). The RT plans which required major modification according to the tumor subtype were as follows: head and neck (104/904, 12%), thoracic (12/199, 6%), gastrointestinal (33/687,5%), skin (5/106, 5%), genitourinary (16/359, 4%), breast (104/2387, 4%), central nervous system (36/846, 4%), sarcoma (11/277, 4%), pediatric (7/251, 3%), lymphoma (10/423, 2%), gynecological tumors (2/359, 1%), and others (11/351, 3%). CONCLUSION: Multi-disciplinary standardized QA chart rounds provide a comprehensive and an influential method on RT plans and/ or treatment decisions.

Objective To identify and to determine the antimicrobial susceptibility of Acinetobacter baumannii (A. baumannii) clinical isolates from ICU at Aseer Central Hospital. Methods The study was conducted in the Intensive Care Unit, Aseer Central Hospital, Saudi Arabia over 13 months period (2014-2015). Acinetobacter species (n = 105) were isolated from various clinical samples. Isolates were identified using selected phenotypic criteria and confirmed using the Vitek 2 automated system. This system was used to determine the susceptibilities of 21 antimicrobial agents. Patients, isolates and drug data were analyzed using the SPSS statistical software package to determine some epidemiological and microbiological patterns. Results Of the 105 stains, A. baumannii accounted for 49 (46.67%), A. baumannii complex, 19 (18.09%), A. baumannii/haemolyticus 32 (30.47), Acinetobacter haemolyticus 4 (3.81%), Acinetobater lwoffii 1 (0.95%) and unidentified Acinetobater species 2 (1.3%). Of the 105 Acinetobacter strains, 103 (98.1%) were found multidrug resistant (MDR). A. baumannii strain were 100% sensitive to colistin and 74.5% to trimethoprim + sulfamethoxazole. The remaining 19 antimicrobial agents revealed low or no sensitivities: amikacin 16.3%; ampicillin 7.7%; ceftazidime, 7.3%. Distribution of similar sensitivities was shown by other Acinetobacter species. Mean number of isolates from males and females indicates no statistical variation (P = 0.867) whereas age groups showed significant differences (P = 0.008) as it is clear from the high percentage of infected individuals more than 60 years followed by those aged 20-29 years old (19.05%). Upper respiratory tract (30.48%), lower respiratory tract (47.65%) and subcutaneous tissue (9.5%) were the main sources of Acinetobacter spp. but mean numbers of isolates from these specimens indicate no discrepancy between specimens (P = 0.731). Conclusions Acinetobacter species including A. baumannii were found MDR (98.1%) according to the current Acinetobacter spp. antimicrobial categorization. Approximately half of these strains were A. baumannii. All Acinetobacter species were 100% sensitive to colistin and to some extent to trimethoprim + sulfamethoxazole (74.5%). ICU-acquired pneumonia among patients over 60 years of age who spend prolong times at artificial ventilations made up the majority of the cases.

Aim:This study aims to assess the wet market wastewater efficiency as Scenedesmussp. biomass production medium based on the physical and chemical characteristic as well as the biomass compositions. Methodology and results:The experiments were set up in transparent glass tank (40 L) containing 20 L of wastewater. The efficiency of different concentrations (10, 15, 20 and 25%) of wet market wastewater diluted with distilled water was compared to Bold Basal Medium (BBM). The biomass was harvested after 12 days of the incubation period by centrifugation. The quantity of biomass yielded was estimated based on the microalgae cell concentrations, while quality of biomass yield was determined by GC-MS. The nutrient contents of the raw wet market wastewater were in the range required for microalgae growth. The wastewater with 20% of dilution exhibited high efficiency for Scenedesmussp. growth in comparison to BBM (4×107vs.1 ×106cell/mL respectively). The main compounds in the microalgae biomass included cycloheptane, cyclododecanol, 1-ethenyl-acetate, 2-trifluoroacetoxypentadecane and 9-octadecenoic acid (Z)-, methyl ester.Conclusion, significance and impact of study:Scenedesmussp. biomass can be produced using the wet market wastewate
