Makna Istikbār dalam Al-Qur’an: Perspektif Semantik Toshihiko Izutsu
Many people misinterpret the word istikbar. Some think that the word has the same meaning with takabbur. By considering the frequent use of the word in daily life, and also seeing the various it is expressed in the Quran, a broader and more detailed understanding of the word istikbār is needed. The research problem here is what is the meaning of istikbar in Al-Qur’an based on Toshiko Izutsu’s semantic approach? This is a library research. The method used is the thematic one. Since this study of the term is focused on language, researcher uses the semantic approach and chooses Toshihiko Itsuzu’s semantic theory. The result shows that 1) the basic meaning of istikbar are great, noble, majestic and al-ta’azhum, 2) syntagmatically the
relational meaning of istikbar are reluctant, deny, disbelieve and turn away. While paradigmatically the meanings are divided into two, synonym and antonym. Its synonyms are arrogant and bragging, and its antonym are humble and gentle, 3) its historical meaning are bragging, arrogant, reluctant, 4) its weltanschauung is bragging
The outcomes of carbapenem resistant enterobacteriaceae (CRE) infected patients and their association with antibiotic therapy
Introduction
Carbapenem Resistant Enterobacteriaceae (CRE) especially Carbapenem producing
CRE (CP-CRE) has emerged as a global threat which commonly associated with
hospital acquired infection including blood stream infection, pneumonia, surgical site
infection and urinary tract infection. Overall, isolation of CRE from any site
whether this represents clinical infection or not was associated with poor outcomes.
Despite their increasing burden, the most optimal treatment for CRE infections was
largely unknown. Therefore, the aim of this study is to determine the outcomes of
CRE infected patients and their association with antibiotic therapy.
Methods
This was a retrospective study conducted in Hospital Universiti Sains Malaysia
from January 2013 till March 2017. The l ist of CRE cases se lected from
Medical Microbiology & Parasitology laboratory. Patient‟s records were reviewed for
demographics and clinical characteristics and those that meet the inclusion and
exclusion criteria were included in this study. Archived isolates were further tested for
MIC testing for meropenem, imipenem, ertapenem, doripenem and polymyxin B by
using E test method. The results were interpreted according to CLSI guidelines. Data
were analysed using SPSS Statistic version 22.
Results
A total of 57 CRE infected patients and started on targeted antimicrobial therapy was
included in the study. The most common infection related to CRE infection was
pneumonia (29/57, 50.9%) followed by blood stream infection (15/57, 26.3%) and
urinary tract infection (7/57, 12.3%) with Klebsiella pneuomoniae as a major CRE
pathogen (54/57, 94.7%). Most of the patients were located in a medical ward and ICU,
accounting for 42.1% (24/57) and 33.3% (19/57) respectively of the subjects. Majority
of patients had underlying disease and the most common disease was chronic kidney
disease (38.6%, 22/57) followed by diabetes mellitus (36.8%, 21/57). The all-30-day
mortality in this study was 43.9% (42/57). Based on in vitro susceptibility testing on
carbapenems, imipenem has the highest sensitivity rate (9/57, 15.8%) followed by
meropenem (7/57, 12.3%) according to CLSI breakpoint 2012. All isolates were
susceptible to polymyxin B. Most of the subjects in this study received monotherapy
(33/57, 57.9%) compared to combined therapy (24/57, 42.1%). We found that no
significant association between patient‟s outcome with monotherapy or combined
therapy (p = 0.113) and also with the type of antimicrobial received. However, the 30-
day mortality in combined therapy group much higher (13/23, 56.5%) if compare to
monotherapy group (12/34, 35.3%). Out of 45 repeated samples cases, 82.2% (37/45)
had achieved microbiological clearance. We found that no significant association
between meropenem MIC levels with microbiological clearance (p = 0.641).
Conclusion
Overall, based on in vitro susceptibility testing polymyxin B is considered to be the
most active in vitro agents against CRE. However, imipenem and meropenem still have
a role in treating CRE infection especially as a combination therapy. Even though no
significant association was found between antibiotic therapy with the outcome but the
30-day mortality in combined therapy group much higher than monotherapy group. This
could be bias as combined therapy was started among severe infection and critically ill
patients. A larger sample size and prospective study (randomised control trial) may be
needed to prevent bias in term of patient‟s selection on starting type of treatment

Bortezomib attenuates HIF-1- but not HIF-2-mediated transcriptional activation
Bortezomib is the first proteasomal inhibitor (PI) to be used therapeutically for treating relapse cases of multiple myeloma and mantle cell lymphoma. A proposed mechanism for its action is that it prevents the proteasomal degradation of proapoptotic proteins, leading to enhanced apoptosis. Although the α subunit of hypoxia‑inducible factor (HIF)‑1 is not degraded with bortezomib treatment, the heterodimeric HIF‑1 fails to transactivate target genes. HIF‑1 and HIF‑2 are related hypoxia‑inducible transcription factors that are important for the survival of hypoxic tumor cells. The majority of reports have focused on the effects of bortezomib on the transcriptional activities of HIF‑1, but not HIF‑2. The present study investigated the effects of bortezomib on HIF‑2 activity in cancer cells with different levels of HIF‑1α and HIF‑2α subunits. HIF‑α subunit levels were detected using specific antibodies, while HIF transcriptional activities were evaluated using immunodetection, reverse transcription‑polymerase chain reaction and luciferase reporter assay. Bortezomib treatment was found to suppress the transcription and expression of CA9, a HIF‑1‑specific target gene; however, it had minimal effects on EPO and GLUT‑1, which are target genes of both HIF‑1 and HIF‑2. These data suggest that bortezomib attenuates the transcriptional activity only of HIF‑1, and not HIF‑2. This novel finding on the lack of an inhibitory effect of bortezomib on HIF‑2 transcriptional activity has implications for the improvement of design and treatment modalities of bortezomib and other PI drugs
