تشخيص ضغوط العمل بين الأطباء الاختصاص ومدى انعكاسه على الرضا الوظيفي بحث استطلاعي على عينة من المستشفيات العامة في محافظة ذي قار
Authors: زوري جبار عناد الغزي مشعل 
Published: March 2023

يتعرض القطاع الصحي في العراق في الوقت الراهن الى معوقات متعددة، وبخاصة المستشفيات، وقد انعكس ذلك على أداء الأطباء الاختصاص الذين تعتمد على خدماتهم المستشفيات، ويعد الأطباء الاختصاص هم ثروة لابد من المحافظة عليها وتنميتها، ولكن للأسف يتعرض هؤلاء الأطباء الى ضغوط متنوعة، منها ضعف وعي المجتمع وتفشي الطابع القبلي في المحافظات العراقية، ولذلك يتعرض الأطباء الى ضغوط بالاعتداء بعض الأحيان، ومن ناحية أخرى وجود نقص في الملاكات الطبية وقد برزت هذه المشكلة اثناء تفشي جائحة كورونا، وبرزت عوامل أخرى وهي قلة المستلزمات والأجهزة الطبية، وقد برزت ظاهرة الدوران الوظيفي الخارجي للأطباء الاختصاص، مما انعكس على أداء المستشفيات في محافظة ذي قار عينة البحث، وتأتي أهمية البحث الحالي في تشخيص الأسباب الأساسية من هجرة الأطباء من المستشفيات وضعف اداءهم وتلكؤ في أداء واجباتهم الوظيفية، لذا يهدف البحث إلى تشخيص ضغوط العمل من وجهة نظر الاطباء الاختصاص في المستشفيات ومدى انعكاسه على الرضا الوظيفي. ونسعى الى تطوير نموذج لقياس ضغوط العمل ومدى تأثيره على الرضا الوظيفي، واستكشاف اي من ابعاد ضغوط العمل اكثر تأثيرا في الرضا الوظيفي. تم الاستعانة بالمنهج الوصفي الاستطلاعي، للتعرف على اراء الأطباء بخصوص ضغوط العمل والرضا الوظيفي، وكانت الاستبانة هي الأداة الرئيسة لجمع البيانات، وقد اتم اختيار ثلاث مستشفيات مهمة من مستشفيات محافظة ذي قار، وهي (مستشفى الحسين العام التعليمي، ومستشفى محمد الموسوي، ومستشفى الحبوبي العام التعليمي)، والتي تخدم ما يقارب (815) سريرا، وقد تم استهداف الأطباء الاختصاص كونهم الاكثر تحملا للمسؤولية، وجرى اختبار الفرضيات من خلال استخدام بعض المعالجات الاحصائية، لقد تم توزيع الاستبانة على 68 طبيبا، واسفرت النتائج الى وجود ضغوط عمل عالية لدى الأطباء العاملين في المستشفيات الحكومية، وقد انعكس عبء العمل وصراع الدور وانعدام العدالة التنظيمية الى انخفاض في مستوى رضا الأطباء العاملين في المستشفيات المبحوثة في محافظة ذي قار. توصل البحث إلى اتفاق العينة على ان ضغوط العمل في المستشفيات الحكومية تؤدي الى عدم رضا الأطباء في مستشفياتهم، وهذا يولد انخفاض الأداء والتوتر في العمل، وقد أظهرت النتائج ان صراع الدور وعبئ العمل وعدم العدالة في الوظيفة تؤدي الى المزيد من ضغوط العمل. يبين هذا البحث اسباب ضغوط العمل على الاطباء الاختصاص في المستشفيات الحكومية، ومحاولة معالجة الاسباب وتوفير بيئة عمل ملائمة تعزز من اداء الاطباء في المستشفيات . تتعهد هذه الدراسة بمساعدة مقدمي الخدمة الصحية في القطاع الصحي لمعالجة التحدي المتمثل في زيادة ضغوط العمل والعمل على الحد منها، وتعزيز الرضا الوظيفي للاطباء.

The common bean is a legume capable of performing biological nitrogen fixation (BNF). The objective of this work was to evaluate the effect of the application of rock powder associated with inoculation of Bradyrhizobium spp. in isolation or associated on the relative chlorophyll index in common bean leaves. Two experiments were conducted at the Federal Institute of Paraná Campus (IF-PR) in Ivaiporã- PR with four treatments and four completely randomized replicates. The treatments were: Inoculation of seeds with Bradyrhizobium spp; Inoculation of Bradyrhizobium spp. with basalt application; basalt application and control. The chemical analysis of the soil was performed. The seeds were inoculated with MasterFix based on Bradyrhizobium spp. following the manufacturer's recommendations. The relative chlorophyll index (IRC) was evaluated after the opening of the second trifoliate leaf. The IRC in experiment 1 was evaluated at 23, 38 and 53 days after sowing. In experiment 2, the IRC of the plants was evaluated at 25 and 41 days after sowing. The significant effect of treatments at 38 and 53 DAP was verified in relation to IRC, when the plants were cultivated with application of rock powder associated or not with Bradyrhizobium spp. There were treatment effects in relation to IRC in plants inoculated with Bradyrhizobium spp. and inoculated with Bradyrhizobium spp associated with rock powder, when compared with basalt powder and control. There was benefit of increased IRC in both treatments inoculated with Bradyrhizobium spp.

Amaç: Klebsiella pneumoniae ve Acinetobacter baumannii başta olmak üzere dirençli gram negatif mikroorganizmalar yaşamı tehdit eden enfeksiyonlara neden olmaktadır. Bu nedenle Klinik izolatların antibiyotik duyarlılıklarının en kısa sürede ve doğru tespiti kritik öneme sahiptir. Günümüzde karbapenem direnci fenotipik ve/veya genotipik yöntemlerle belirlenmektedir. Fenotipik yöntemlerde (disk difüzyon, mikrodilüsyon) için, hem özgüllük hem de duyarlılık açısından farklılıklar sıklıkla ortaya çıkabilmektedir. Nispeten daha güvenilir sonuçlar veren polimeraz zincir reaksiyonu gibi moleküler metotlar ise iş gücü gerektiren ve yüksek maliyetli yöntemler olduğundan, antibiyotik direncini saptamaya yönelik hızlı, güvenilir ve ekonomik yeni yöntemlere ihtiyaç duyulmaktadır.
Gereç ve Yöntem: Çalışmada kromojenik AST Fast ES/NF agar besiyerinin EUCAST standart disk difüzyon metoduyla antibiyotik duyarlılıklarının saptanmasında kullanımının uygunluğu araştırılmıştır. Karbapenem dirençli olduğu moleküler yöntem/otomatize sistemle belirlenen dört K.pneumoniae ve beş A.baumannii izolatıyla çalışılmıştır.
Sonuç ve Tartışma: Çalışma sonucunda AST Fast ES/NF agar besiyerinde inhibisyon zon çaplarının 4-6 saat içerisinde ölçülebilir duruma geldiği belirlenmiş ve üretici firmanın önerilene uygun şekilde izolatların duyarlılıkları belirlenmiştir. MHA kullanılarak gerçekleştirilen disk difüzyon test sonuçlarının, AST Fast ES/NF agar kromojenik besiyeriyle elde edilen sonuçlar ile büyük oranda uyumlu olduğu belirlenmiştir. Standart disk difüzyon test yönteminde önerilen inkübasyon süresinin 16-20 saat olduğu ve ancak bu süre sonunda duyarlılık kategorisinin belirlendiği düşünüldüğünde kromojenik besiyerinin zaman açısından önemli bir avantaj sağlayabileceği düşünülmektedir.

Enter Sandman
Authors: Fazekas Sándor 
Published: March 2023

A tanulmány azt vizsgálja, hogyan lehet a mai ifjúság mediális eszközeivel, a nekik szóló formanyelvet megújítva megszólaltatni a múlt kiemelkedő értékeit. Neil Gaiman Sandman-sorozata (1989-1996) az első olyan képregény volt, amely World Fantasy-díjat kapott; persze itt sem a díj fontos, önmagában, hanem az, amit jelent. Olyan világirodalmi műveket helyezett új kontextusba, és juttatott el az olvasókhoz, mint Shakespeare Szentivánéji álom, vagy a Vihar című drámája, sőt, Dante Isteni színjátéka és Milton Elveszett Paradicsoma is nagy hatást gyakorolt rá. Gaiman képes arra, hogy a fiatalok által ismert és szeretett Marvel-univerzumhoz illessze főhőse, Morpheus (az Álom istenséghez hasonló, de emberi külsejű megtestesítője) történetét, aki különböző világokon halad keresztül, s időnként klasszikus irodalmi alakokkal (mint maga Shakespeare, vagy Lucifer Milton művéből), időnként pedig Marvel-szuperhősökkel találkozik. Mindezt úgy, hogy a történet saját belső logikája nem szenved csorbát; a dolgozat a magyarul is többször megjelent Sandman mediális, illetve narratív elemzésére is törekszik. Sokat tanulhatunk az angolszász ismeretterjesztő hagyományból, hiszen adósak vagyunk még a merészebb átiratokkal, adaptációkkal, különösen ami a képregényeket illeti. Szerencsére idehaza is van képregény-kultusz, a lehetősége tehát megvan annak, hogy ez a műfaj ezen a téren is továbbfejlődjön: az igényes formai kialakítású darabok mellett ne csak exportált legyen a csúcsminőség. Az lenne az igazán jó, ha túllépnénk az egyszerű képregény-átiratokon, és egy irodalomelméletileg megalapozott, súlyos tartalmakat is hordozó koncepcióba ágyazva, a modern formanyelv tökéletes ismeretében tudnánk hasonló kvalitású alkotásokat létrehozni. A dolgozat természetesen kitér arra a kérdésre is, hogy milyen eszközöket használunk idehaza, illetve arra is, hogyan alkalmazzák a képregény-műfajt a klasszikus alkotások népszerűsítésére.

Published: March 2023

Introduction: In clinical work, the realization of an early diagnosis of Subarachnoid hemorrhage (SAH) is primarily based on conventional computed tomography (CT), MR angiography, transcranial Doppler (TCD) ultrasound, and neurological assessments. However, the association between imaging manifestations and clinical findings is insufficiently perfect, particularly in SAH patients in acute phases with a lower amount of blood. The establishment of a direct, rapid and ultra-sensitive detection method based on electrochemical biosensors has emerged as a new competitive challenge in disease biomarkers research.Methods: In this study, a novel free-labeled electrochemical immunosensor for rapidly and sensitively detecting IL-6 in subarachnoid hemorrhage (SAH) blood has been developed using Au nanospheres-thionine composites (AuNPs/THI) as the interface modified on the electrode. Then, we detected IL-6 in blood samples from SAH patients by (enzyme-linked immunosorbent assay) ELISA and electrochemical immunosensor.Results: Under the best conditions, the developed electrochemical immunosensor exhibited a wide linear range from 10−2 ng/mL to 102 ng/mL with a low detection limit of 1.85 pg/mL. Furthermore, when the immunosensor was employed in the analysis of IL-6 in 100% serum, the results obtained by electrochemical immunoassay were consistent with those obtained by ELISA without suffering from other significant biological interference.Discussion: The designed electrochemical immunosensor realizes the detection of IL-6 in actual serum samples with high accuracy and sensitivity, and could potentially become a promising technique for applications in the clinical diagnosis of SAH.

Published: March 2023

Objective:Compare biomechanical properties of femurs implanted with either BioMedtrix™biological fixation with interlocking lateral bolt (BFX®+lb) or cemented (CFX®) stems when subjected to 4-point bending or axial torsional forces.Study Design:Twelve pairs of normal medium to large cadaveric canine femora were implanted with a BFX + lb (n= 12) and a CFX (n= 12) stem–one in the right and one in the left femora of the pair. Pre- and post-operative radiographs were made. Femora were tested to failure in either 4-point bending (n= 6 pairs) or axial torsion (n= 6 pairs), and stiffness, load or torque at failure, linear or angular displacement, and fracture configuration were noted.Results:Implant position was acceptable in all included femora, but CFX stems were placed in less anteversion than BFX + lb stems in the 4-point bending group (median (range) 5.8 (−1.9–16.3) vs. 15.9 (8.4–27.9) anteversion, respectively (p= 0.04)). CFX implanted femora were more stiff than BFX + lb implanted femora in axial torsion (median (range) 2,387 (1,659–3,068) vs. 1,192 (795–2,150) N*mm/o, respectively (p= 0.03)). One of each stem type, from different pairs, did not fail in axial torsion. There was no difference in stiffness or load to failure in 4-point bending, or in fracture configuration for either test, between implant groups.Conclusion:Increased stiffness of CFX implanted femurs under axial torsional forces may not be clinically relevant as both groups withstood expectedin vivoforces. Based on this acute post-operative model using isolated forces, BFX + lb stems may be a suitable replacement for CFX stems in femurs with normal morphology (stovepipe and champagne flute morphology were not tested).

Published: March 2023

BackgroundAtrial fibrillation (AF) and heart failure (HF) often coexist. The treatment of AF in patients with HF has been challenging because of the ongoing debate about the merits of catheter ablation vs. drug therapy.MethodsThe Cochrane Library, PubMed, and www.clinicaltrials.gov were searched until June 14, 2022. Inclusion criteria were catheter ablation compared with drug therapy in adults with AF and HF in randomized controlled trials (RCTs). Primary outcomes consisted of all-cause mortality, re-hospitalization, change in left ventricular ejection fraction (LVEF), and AF recurrence. Secondary outcomes referred to quality of life [QoL; measured by the Minnesota Living with Heart Failure Questionnaire (MLHFQ)], six-minute walk distance (6MWD), and adverse events. The PROSPERO registration ID was CRD42022344208.FindingsIn total, nine RCTs with 2,100 patients met the inclusion criteria, with 1,062 for catheter ablation and 1,038 for medication. According to the meta-analysis, catheter ablation significantly reduced all-cause mortality compared with drug therapy [9.2% vs. 14.1%, OR: 0.62, (95% CI: 0.47–0.82), P = 0.0007, I2 = 0%], improved LVEF [MD: 5.65%, (95% CI: 3.32–7.98), P &lt; 0.00001, I2 = 86%], reduced AF recurrence [41.6% vs. 61.9%, OR: 0.23, (95% CI: 0.11–0.48), P &lt; 0.0001, I2 = 82%], decreased the MLHFQ score [MD: −6.38, (95% CI: −11.09 to −1.67), P = 0.008, I2 = 64%] and increased 6MWD [MD: 17.55, (95% CI: 15.77–19.33), P &lt; 0.0001, I2 = 37%]. Catheter ablation did not increase the re-hospitalization [30.4% vs. 35.5%, OR: 0.68, (95% CI: 0.42–1.10), P = 0.12, I2 = 73%] and adverse events [31.5% vs. 30.9%, OR: 1.06, (95% CI: 0.83–1.35), P = 0.66, I2 = 48%].InterpretationIn AF patients with HF, catheter ablation improves exercise tolerance, QoL, and LVEF and significantly reduced all-cause mortality and AF recurrence. Although the differences were not statistically significant, the study found lower re-hospitalization and approximate adverse events with improved catheter ablation tendency.PROSPERO registration IDCRD42022344208.
Biomimetic, antiadhesive surface structure inspired by the calamistra setae of cribellate spiders for electrospun nanofiber handling
Authors: Lifka Sebastian , Stecher Christoph , Meyer Marco , Joel Anna-Christin , Heitz Johannes , Baumgartner Werner 
Published: March 2023

IntroductionDue to their excellent surface-to-volume ratio, nanofibers (i.e., fibers with a diameter of approximately 10 to 800 nm) are of increasing interest to engineers and scientists in a broad spectrum of applications. However, due to van der Waals forces, these nanofibers tend to adhere strongly to any surface, which makes further processing very challenging. In nature, we find animals that can easily handle nanofibers: Cribellate spiders use a comb-like structure, the so-called calamistrum, to produce, handle, and process nanofibers. Due to a fingerprint-like surface nanostructure, nanofibers do not adhere to the calamistrum. The principle interaction between this fingerprint-like surface nanostructure and single nanofibers has recently been described in a publication. The fingerprint-like surface structure was replicated on a technical metal surface using laser-induced periodic surface structures, which resulted in material properties resembling those of the natural model.MethodsWe went a step further and took a closer look on an additional structural feature of the calamistrum much larger than the fingerprint-like surface structure. A theoretical approach to describing the influence of a fiber preload, which may become a dominant effect if the fiber dimensions are small compared to the surface structure dimensions, on the adhesion of the fiber to these large surface structures was derived. Our theory was verified experimentally for artificial electrospun polyamide 6 nanofibers on surface-structured samples made of titanium alloy.Results and ConclusionA dramatic reduction in adhesion compared to unstructured, flat surfaces was proven. Therefore, such a surface structure can be used for tools or parts of tools during nanofiber production (e.g., as part of the electrospinning process) to reduce the adhesion of the nonwoven fabric and thus facilitate the handling and processing of the nanofibers during production.

Sericinus montelus (Lepidoptera, Papilionidae, Parnassiinae) is a high-value ornamental swallowtail butterfly species widely distributed in Northern and Central China, Japan, Korea, and Russia. The larval stage of this species feeds exclusively on Aristolochia plants. The Aristolochia species is well known for its high levels of aristolochic acids (AAs), which have been found to be carcinogenic for numerous animals. The swallowtail butterfly is among the few that can feed on these toxic host plants. However, the genetic adaptation of S. montelus to confer new abilities for AA tolerance has not yet been well explored, largely due to the limited genomic resources of this species. This study aimed to present a chromosome-level reference genome for S. montelus using the Oxford Nanopore long-read sequencing, Illumina short-read sequencing, and Hi-C technology. The final assembly was composed of 581.44 Mb with an expected genome size of 619.27 Mb. Further, 99.98% of the bases could be anchored onto 30 chromosomes. The N50 of contigs and scaffolds was 5.74 and 19.12 Mb, respectively. Approximately 48.86% of the assembled genome was suggested to be repeat elements, and 13,720 protein-coding genes were predicted in the current assembly. The phylogenetic analysis indicated that S. montelus diverged from the common ancestor of swallowtails about 58.57–80.46 million years ago. Compared with related species, S. montelus showed a significant expansion of P450 gene family members, and positive selections on eloa, heatr1, and aph1a resulted in the AA tolerance for S. montelus larva. The de novo assembly of a high-quality reference genome for S. montelus provided a fundamental genomic tool for future research on evolution, genome genetics, and toxicology of the swallowtail butterflies.
