The concentrations of fibronectin in aqueous humor, measured by ELISA which was developed to detect fibronectin, ranged from 5 ng/ml to 100 ng/ml. Aqueous humor was aspirated from human eyes with cataracts and glaucomas using a 26 gauge needle through the peripheral cornea before making the limbal incision into the anterior chamber during surgery. The results of the study show that the average concentration and standard deviation of fibronectin was 0.136 +/- 0.192 microgram/ml in cataract eyes, and 0.962 +/- 0.918 microgram/ml in glaucoma eyes respectively. There was a statistically significant difference between both groups (p = 0.000). However, no significant differences according to age and sex were noted. There was no influence due to preoperative intravenous mannitol injection on fibronectin concentration. The source of aqueous fibronectin is still not clearly known and the mechanism of the higher concentration of fibronectin in glaucoma has not been clearly disclosed, however it is thought that normally present fibronectin is accumulated in the anterior chamber because it can not pass the aqueous outflow pathway, or that fibronectin production may be increased in glaucoma.

Background: Preoperative anxiety is a significant problem
worldwide that may affect patients’ surgical outcome. By
using a simple and reliable tool such as the Amsterdam
Preoperative Anxiety and Information Scale (APAIS),
anaesthesiologists would be able to assess preoperative
anxiety adequately and accurately.
Objective: The purpose of this study was to develop and
validate the Malay version of APAIS (Malay-APAIS), and
assess the factors associated with higher anxiety scores.
Methods: The authors performed forward and backward
translation of APAIS into Malay and then tested on 200
patients in the anaesthetic clinic of University Malaya
Medical Centre. Psychometric analysis was performed with
factor analysis, internal consistency and correlation with
Spielberger’s State-Trait Anxiety Inventory (STAI-state).
Results: A good correlation was shown with STAI-state (r =
0.59). Anxiety and need for information both emerged with
high internal consistency (Cronbach’s alpha 0.93 and 0.90
respectively). Female gender, surgery with a higher risk and
need for information were found to be associated with
higher anxiety scores. On the other hand, previous
experience with surgery had lower need for information.
Conclusion: The Malay-APAIS is a valid and reliable tool for
the assessment of patients’ preoperative anxiety and their
need for information. By understanding and measuring
patient’s concerns objectively, the perioperative
management will improve to a much higher standard of care.
5. Testicular fine-needle aspiration for the assessment of intratesticular hormone concentrations
Asian Journal of Andrology 2016;18(1):21-24
Measurement of intratesticular sex steroid concentrations in men informs both the development of male hormonal contraceptives and the understanding of male infertility. Given the challenges of using invasive techniques to measure testicular hormone physiology, our group has used a minimally-invasive fine-needle aspiration technique to measure intratesticular hormones in normal healthy men. Herein, we present a post-hoc analysis of the safety and efficacy of testicular fine-needle aspiration (FNA) completed as part of six clinical trials. From 2001 through 2011, a total of 404 procedures were conducted among 163 research volunteers, 85.9% of which were successful in obtaining sufficient fluid for the measurement of intratesticular steroid concentrations. Pain was the most common side effect, with 36.8% of procedures associated with moderate procedural pain and 4.7% with severe procedural pain. Postprocedural pain was uncommon and abated within a few days. Mild local bruising occurred with 14.9% of procedures. Two serious adverse events (0.5%) required surgical intervention. The risk of an adverse event was not associated with age, body mass index, testicular size, or the volume of fluid aspirated. Testicular FNA to obtain fluid for measurement of intratesticular steroid concentrations frequently causes mild to moderate procedural pain, but serious adverse events occur rarely. Testicular FNA has been instrumental for defining human intratesticular hormone physiology and is a minimally-invasive, safe, effective method for obtaining fluid for research on testicular physiology and pathology.
6.Recent Developments in the Therapeutic Landscape of Advanced or Metastatic Hormone Receptor–Positive Breast Cancer

Hormone receptor–positive (HR+) disease is the most frequently diagnosed subtype of breast cancer. Among tumor subtypes, natural course of HR+ breast cancer is indolent with favorable prognosis compared to other subtypes such as human epidermal growth factor protein 2–positive disease and triple-negative disease. HR+ tumors are dependent on steroid hormone signaling and endocrine therapy is the main treatment option. Recently, the discovery of cyclin-dependent kinase 4/6 inhibitors and their synergistic effects with endocrine therapy has dramatically improved treatment outcome of advanced HR+ breast cancer. The demonstrated efficacy of additional nonhormonal agents, such as targeted therapy against mammalian target of rapamycin and phosphatidylinositol 3-kinase signaling, poly(ADP-ribose) polymerase inhibitors, antibody-drug conjugates, and immunotherapeutic agents have further expanded the available therapeutic options. This article reviews the latest advancements in the treatment of HR+ breast cancer, and in doing so discusses not only the development of currently available treatment regimens but also emerging therapies that invite future research opportunities in the field.

8.Twin Pregnancy and Delivery After Intracytoplasmic Sperm Injection Followed by Calcium Ionophore with Spermatozoa from a Globozoospermic Man: A Case Report.

Our purpose is to describe a successful twin pregnancy and delivery after intracytoplasmic sperm injection (ICSI) followed by calcium ionophore with spermatozoa from a globozoospermic man. On the second attempt of ICSI, all of eight metaphase II oocytes were fertilized with treatment with calcium ionophore. Day 3 transfer of six normally developing embryos resulted in an ongoing twin pregnancy, and two preterm healthy babies were born in the 33th week of gestation. To the best of our knowledge, this is the first report of pregnancy and delivery after ICSI followed by calcium ionophore with spermatozoa from a globozoospermic man in Korea.

9.Securing patient access to new medical technology under the diagnosis-related group system in South Korea: a review of foreign policies and selective reimbursement coverage programs for 4 major conditions.

The Korean government operates a fee-for-service system, as well as a diagnosis-related group (DRG) payment system that only applies to 7 different specific disease groups. To control rapidly increasing health expenditures, the Korean government adopted a compulsory DRG payment system for 7 disease groups in 2013. However, the current Korean DRG (K-DRG) system does not address the cost of new medical technologies and accompanying services, whereas the United States and European countries have implemented incentive systems within the DRG payment system to promote technological innovations. The Korean government is expanding the accessibility of new medical technologies to strengthen the coverage of 4 major conditions with a selective reimbursement system, but the K-DRG system is inconsistent with the selective reimbursement system in terms of adopting new medical technology. Such inconsistency is clearly shown in the case of advanced energy devices that are essential for surgical procedures. Despite their clinical usefulness and the high demand for such instruments, there is little space for compensation for advanced energy devices in DRG groups. Neither healthcare providers nor patients can choose selectively reimbursed medical devices under the current DRG system, leading to unequal healthcare benefits among patient groups. This paper proposes additional payments for new medical technology that is costly but clinically effective to ensure patient access to new medical technology under the K-DRG system, and suggests that a fair and consistent policy would be to apply the selective reimbursement of medical services in K-DRG.
