Infective endocarditis secondary to Serratia marcescens is very rare, noted in patients with severe immunosuppresion. The disease is associated with high mortality. Therefore early diagnosis and aggressive treatment is recommended.The Saudi government is currently facing multiple challenges in achieving "The Gold Standard" in nursing practice. This is not limited to educational challenges, staffing shortage, paucity of international and national benchmark evidence, absence of clear and defined scope of nursing practice, and lack of appropriate policies and regulations. This study presented a comprehensive plan for developing a policy based on current challenges, recognition of policy goals, assessment of potential options and alternatives, identification of stakeholders, proposition of recommended solutions, and implementation of the framework to transform nursing standards and link these changes with the Saudi Vision 2030. However, amendments are required in the present strategic plan for the better management of the nursing profession. It is doubtful that the current nursing profession status quo is capable of meeting the golden standards for health care. Thus, the transformation of the nursing profession in Saudi Arabia is necessary.Metabolic engineering aims to maximize the production of bio-economically important substances (compounds, enzymes, or other proteins) through the optimization of the genetics, cellular processes and growth conditions of microorganisms. This requires detailed understanding of underlying metabolic pathways involved in the production of the targeted substances, and how the cellular processes or growth conditions are regulated by the engineering. To achieve this goal, a large system of experimental techniques, compound libraries, computational methods and data resources, including multi-omics data, are used. The recent advent of multi-omics systems biology approaches significantly impacted the field by opening new avenues to perform dynamic and large-scale analyses that deepen our knowledge on the manipulations. However, with the enormous transcriptomics, proteomics and metabolomics available, it is a daunting task to integrate the data for a more holistic understanding. Novel data mining and analytics approaches, including Artificial Intelligence (AI), can provide breakthroughs where traditional low-throughput experiment-alone methods cannot easily achieve. Here, we review the latest attempts of combining systems biology and AI in metabolic engineering research, and highlight how this alliance can help overcome the current challenges facing industrial biotechnology, especially for food-related substances and compounds using microorganisms.We presented a patient with CML who progressed to unclassical blast phase after Tyrosine Kinase Inhibitors (TKIs) therapy. The patient presented with 2 populations of blasts one with no cytoplasmic granules and was CD117 weak+/tryptase-/CD34- (typical myeloblasts), and another with metochromatic granules in the cytoplasm and was CD117 strong+/tryptase+/CD25+/CD34 subset+ (myelomastocytic blasts). Almost all the cells were positive for BCR/ABL1 fusion and no KT V816F mutation was detected. The patient was misdiagnosed as having blast phase CML with coexisting mast cell leukemia at an outside institute. Three similar cases and previously described myelomastocytic leukemia are reviewed and discussed.Collecting duct carcinoma is a rare neoplasm of the kidney, accounting for only 1-2% of renal tumors. These tumors arise from the principal cells of the renal collecting ducts of Bellini. The majority of patients have lymph node involvement and metastases to lungs, liver, bone, adrenal glands, and brain. We present a case of a 48 year old woman who came to the hospital with a clinical presentation suspicious for pneumonia. One week later her symptoms aggravated. A CT chest and abdominal imaging showed bilateral pulmonary infiltrates, retroperitoneal lymphadenopathy, and left hydroureteronephrosis. She expired after developing acute respiratory failure. An autopsy was performed which revealed chylopericadium of 150 cc; bilateral reticular pattern on the surfaces of the lungs; neck, mediastinal and retroperitoneal lymphadenopathy, and a 5.1 cm left kidney mass located in the mid portion medulla. The kidney tumor was a rhabdoid collecting duct carcinoma. The lungs showed diffuse subpleural lymphangitic spread of the carcinoma. We report a rare case of chylopericardium due to lymphangitic carcinomatosis from a 5.1 cm rhabdoid collecting duct carcinoma not suspected clinically or radiologically. This case highlights the importance of performing autopsies in an era when clinicians heavily rely on high-tech imaging diagnostic modalities.This case reports rare findings on computed tomography of a manifestation of malignant lymphoma, in which diffuse lung shadows appeared as miliary nodules distributed throughout the lungs bilaterally. The patient had a history of surgical treatment of rectal cancer and had received chemotherapy for suspicious liver metastasis. At her current presentation for evaluation suspected miliary tuberculosis on chest radiography, subsequent liver biopsy revealed a mass infiltration of atypical lymphocytes, which was diagnosed as follicular lymphoma. The miliary tuberculosis was suspected more than neoplastic lesions, such as metastatic rectal cancer or malignant lymphoma. Despite repeated bacteriologic tests of various samples, including sputum, urine, bronchial secretion, peripheral blood, bone marrow aspiration, and gastric lavage, all results were negative for mycobacterium tuberculosis. Finally, multiple, small, mass lesions of lymphocytes were demonstrated in the lung obtained from video-assisted thoracic surgery, and a diagnosis of follicular lymphoma was given. The final interpretations of liver mass and military lung lesions were tumor involvement by the follicular lymphoma. see more This radiologic findings of multiple miliary opacities throughout the whole lungs confused definite diagnosis because these images were remarkably similar with miliary tuberculous. This case reminds us to consider a wide variety of differential diagnoses even we assumed to be familiar with radiographic imaging at first glance.
