Abstract
Introduction Type 2 diabetes mellitus (T2DM) is one of the non-communicable diseases which continues to rise in prevalence and mortality rate throughout the years. Drug-related problems (DRPs) are more prevalent among T2DM patients especially those with co-morbidities. Objective The objective of this study was to review and assess the prevalence and characteristics of DRPs among hospitalized type 2 diabetes mellitus patients. Methods The systematic review of the literature was carried out using five online databases: PubMed, Scopus, Google Scholar, Web of Science, and Cochrane Library from the inception of the database until June 2022. Studies included in the review were published in English or Malay language. The data were extracted and assessed using the Joanna Briggs Institute (JBI) critical appraisal tools. Results A total of 939 studies were identified with 20 studies that met inclusion criteria and were included in this systematic review. The overall prevalence of DRPs in all 20 studies ranged from 7% to 94%. The most common DRPs included drug-drug interaction (DDI), adverse drug reaction (ADR), therapeutic effectiveness problems, and inappropriate medication use. Conclusion The most common drug classes involved were antidiabetics (metformin), antihypertensives, antiplatelets and antibiotics. The risk factors contributing to DRPs included the presence of comorbidities, the number of medications, and polypharmacy. To conclude, the rate of DRPs incidence in hospitalized T2DM patients was observed to be high. Further future studies with appropriate study designs and methods of detecting DRPs will be necessary to reduce and prevent DRPs occurrences.

Abstract
Background: It has been reported that children are already practicing self-medication. Indeed, at the children’s age, they are not allowed to self-medicate due to limited knowledge regarding self-medication, leading to inappropriate drug therapy or self-toxicity becoming problems in public health.
Objective: This study aimed to determine how school-age adolescents carry out self-medication behavior.
Methods: The study was designed as a cross-sectional in which data were collected using questionnaire methods. There were 195 students recruited in this study, consisting of SDN Keputih-245 Elementary School students, SMPN 19 Surabaya Junior High School, and SMAN 11 Surabaya Senior High School.
Results: The results showed that most of the students had purchased medicine independently without a doctor’s prescription. The primary source of information regarding self-medication by school students is family. Although most of the respondents stated they always inform their parents or doctors, it has been found that the practice of self-medication by school-age teenagers without informing their parents or doctors exists. Moreover, less than 50% of student respondents believe that self-medication is safe.
Conclusion: The role of pharmacists is urgently needed to pro- vide proper education related to drug information and self-medication to increase school-age students’ knowledge.

Abstract
INTRODUCTION Dementia is a disorder that causes a decline of cognitive function, and it affects millions of people worldwide. Increased availability of medications used to treat dementia will inevitably increase the likelihood of drug-related problems (DRPs). OBJECTIVE This systematic review sought to identify DRPs due to medication misadventures, including adverse drug reactions (ADRs), and use of inappropriate medications, among patients with dementia or cognitive impairments. METHODS The included studies were retrieved from the electronic databases PubMed and SCOPUS, and a preprint platform (MedRXiv) which were searched from their inception through August 2022. The English-language publications that reported DRPs among dementia patients were included. The JBI Critical Appraisal Tool for quality assessment was used to evaluate the quality of studies included in the review. RESULTS Overall, 746 distinct articles were identified. Fifteen studies met the inclusion criteria and reported the most common DRPs, which comprised medication misadventures (n = 9), such as ADRs, inappropriate prescription use, and potentially inappropriate medication use (n = 6). CONCLUSION This systematic review provides evidence that DRPs are prevalent among dementia patients, particularly the older people. It indicates that medication misadventures such as ADRs and inappropriate drug use, as well as potentially inappropriate medications, are the most prevalent DRPs among older people with dementia. Due to the small number of included studies, however, additional studies are required to improve comprehension about the issue.

Abstract
OBJECTIVES Community pharmacist has been widely known as a health professional who can be easily accessed to provide medicines and reliable medicine information. However, this was not always in the case of dispensing natural medicines. Several international studies revealed that community pharmacists were less likely to deliver natural medicines accompanied with detailed information. Therefore, this study aimed to investigate factors influencing Indonesian community pharmacists in the supply of, delivery of, and provision of information about natural medicines. METHODS A qualitative study with purposively selected community pharmacists in four areas (district or municipality) in East Java Province was designed. In-depth, semi-structured interviewed were conducted using a Capability-Opportunity-Motivation-Behaviour approach. All interviews were audio-recorded, transcribed ad verbatim, and thematically analysed. RESULTS Data saturation was reached after interviewing 14 community pharmacists. All informants reported dispensing non-prescribed natural medicines. Nine had experienced dispensing prescribed natural medicines, mainly fulfilling paediatricians' requests. The most common information given was about product usage, while information about safety (i.e. side effects, interaction) was rarely provided. Although numerous registered natural medicines have been available, informants had low motivation to supply a variety of types, primarily because little opportunity to receive requests from doctors and the community. Limited capability due to a lack reliable source of information about natural medicines was another reason. CONCLUSIONS Poor motivation to supply natural medicines was because community pharmacists had little opportunity for such requests and limited capability due to scarcity of information. This indicated support from natural medicine manufacturers, researchers, and the government is highly required.

Abstract
Cell extensions are critical structures that enable matrix remodeling in wound healing and cancer invasion but the regulation of their formation is not well-defined. We searched for new proteins that mediated cell extension formation over collagen by tandem mass tagged mass spectrometry analysis of purified extensions in 3T3 fibroblasts. Unexpectedly, importin-5, ENH isoform 1b (PDLIM5) and 26 S protease regulatory subunit 6B (PSMC4) were more abundant (> 10-fold) in membrane-penetrating cell extensions than cell bodies, which was confirmed by immunostaining and immunoblotting and also observed in human gingival fibroblasts. After siRNA knockdown of these proteins and plating cells on grid-supported floating collagen gels for 6 h, formation of cell extensions and collagen remodeling were examined. Knockdown of importin-5 reduced collagen compaction (1.9-fold), pericellular collagen degradation (~ 1.8-fold) and number of cell extensions (~ 69%). Knockdown of PSMC4 reduced collagen compaction (~ 1.5-fold), pericellular collagen degradation (~ 1.7-fold) and number of cell extensions (~ 42%). Knockdown of PDLIM5 reduced collagen compaction (~ 1.6-fold) and number of cell extensions (~ 21%). Inhibition of the TGF-β RI kinase, Smad3 or ROCK-II signaling pathways reduced the abundance of PDLIM5 in cell extensions but PSMC4 and importin-5 were reduced only by Smad3 or ROCK-II inhibitors. We conclude that these novel proteins are required for cell extension formation and their recruitment into extensions involves the Smad3 and ROCK signaling pathways.

Abstract
BACKGROUND AND OBJECTIVE Cigarette smoking has detrimental effects on periodontal tissue, and is known to be a risk factor for periodontal disease, including the loss of alveolar bone and ligament tissue. However, the direct effects of cigarette smoking on periodontal tissue remain unclear. Recently, we demonstrated that benzo[a]pyrene (BaP), which is a prototypic member of polycyclic aryl hydrocarbons and forms part of the content of cigarettes, attenuated the expression of extracellular matrix remodeling-related genes in human periodontal ligament (PDL) cells (HPDLCs). Thus, we aimed to examine the effects of BaP on the osteoblastic differentiation and collagen synthesis of HPDLCs. MATERIAL AND METHODS HPDLCs were obtained from healthy molars of three patients, and quantitative reverse transcription-polymerase chain reaction were performed for gene expression analyses of cytochrome P450 1A1 and 1B1, alkaline phosphatase, bone sialoprotein and aryl hydrocarbon receptor (AhR), a receptor for polycyclic aryl hydrocarbons. We have also analyzed the role of the AhR, using 2-methyl-2H-pyrazole-3-carboxylic acid (2-methyl-4-o-tolylazo-phenyl)-amide (CH-223191), which is an AhR antagonist. RESULTS The treatment of HPDLCs with BaP reduced mRNA expression of osteogenic genes, alkaline phosphatase activity, mineralization and collagen synthesis. The treatment with CH-223191 subsequently restored the observed suppressive effects of BaP on HPDLCs. CONCLUSIONS The present results suggest that BaP exerts inhibitory effects on the maintenance of homeostasis in HPDL tissue, such as osteoblastic differentiation and collagen synthesis of HPDLCs, and that this signaling pathway could be suppressed by preventing the transactivity of AhR. Future studies may unveil a role for the inhibition of AhR as a promising therapeutic agent for periodontal disease caused by cigarette smoking.

Abstract
A 59-year-old man was admitted to the hospital, suspected of the rupture of descending thoracic aortic aneurysm due to sudden back pain. Enhanced computed tomography revealed a ruptured descending thoracic aortic aneurysm with huge hematoma and abdominal aortic aneurysm. Based on the above diagnosis, we performed urgent operation through left thoracotomy under unilateral lung ventilation. While dissecting the aneurysm, sudden hemodynamics deterioration occurred. Although cardiopulmonary bypass was introduced immediately through femoral artery and femoral vein cannulations, hemodynamics was not improved and unilateral lung ventilation got more unmanageable. We diagnosed right tension hemothorax due to the extension of aneurysm rupture into the right thoracic cavity. After placing a cannula at the distal arch for a central perfusion, we clamped the descending thoracic aorta at both the proximal and distal sites of the aneurysm. Thereafter we opened the aneurysm and drained the right thorax through the aneursym's tear. The aneurysm was replaced with a prosthetic woven-Dacron vascular graft. The patient's postoperative condition had been stable with no significant unfavorable event. The abdominal aortic aneurysm was replaced with a bifurcated graft on 51st postoperative day. He was discharged in good condition on the 69th postoperative day.

Abstract
A 40-year-old woman was admitted to our hospital because of operation for giant intra-pervic tumor. She had a history of deep vein thrombosis. Suddenly she complained severe dyspnea while having a bath, and subsequently cardiogenic shock occurred. Immediately we set up percutaneous cardiopulmonary support (PCPS) for acute pulmonary thromboembolism. Despite thrombolytic therapy including the administration of urokinase and rt-PA, hemodinamics were not improved. Emergent pulmonary embolectomy was performed on-pump beating. Postoperative course was uneventful. The intra-pervic tumor was removed on the 24th postoperative day. She was discharged in good condition on the 38th postoperative day. Quick diagnosis and appropriate therapy are essential in patient with acute massive pulmonary thromboembolism.

Abstract
A 74-year-old man who had previously undergone prosthetic graft replacement of the total aortic arch using the elephant trunk technique and of the abdominal aorta was admitted to our hospital for surgical treatment of descending aortic aneurysm. Computed tomography (CT) on admission revealed descending aortic aneurysm of 6.5 cm in diameter, and the previously placed prosthetic graft was detected in the aneurysm. Surgery for the descending aorta was performed under femoro-femoral partial bypass. During the operation, a balloon occlusion catheter introduced through the right brachial artery into the 'elephant trunk' graft was inflated before the aneurysm was opened, then the previously placed prosthetic graft was cross-clamped and the descending aorta was replaced with a new prosthetic graft with usual fashion. The postoperative course was uneventful.

Abstract
BACKGROUND Vascular tissues of humans and dogs contain chymase as an angiotensin II-forming enzyme. In this study, we investigated whether chymase-dependent angiotensin II formation plays a crucial role in the development of vascular proliferation in dog grafted veins. METHODS AND RESULTS The right external jugular vein of dogs was grafted to the ipsilateral carotid artery. As a control group, the right external jugular veins in dogs that had not received grafts were used. In the chymase inhibitor-treated group, the vein was infiltrated with 10 micromol/L Suc-Val-Pro-Phe(P)(OPh)(2) and was grafted to the carotid artery. In the placebo-treated group, ACE activity in the grafted veins was significantly lower than that in the control veins up to 7 days after the operation, whereas chymase activity was increased significantly. After 7 days, the mRNA levels of collagen I, collagen III, and fibronectin, all of which are induced by an increase of angiotensin II action, were significantly increased in the grafted veins, and the intima-media ratio of the grafted veins was also increased. In the chymase inhibitor-treated group, the chymase activity in the grafted veins 7 days after the operation was suppressed to 12.1%. The elevated mRNA levels of fibronectin, collagen I, and collagen III in the grafted veins were significantly suppressed by treatment with the chymase inhibitor, and the intima-media ratio was also decreased significantly. CONCLUSIONS We demonstrate for the first time that chymase-dependent angiotensin II formation plays an important role in the development of vascular proliferation in the grafted veins.

Abstract
Chymase may play an important role in vascular proliferation, as shown by in-vitro experiments, but the role of chymase in vivo has been unclear. In this study, we investigated the effect of a novel chymase inhibitor, NK3201, on this proliferation in dog grafted veins. NK3201 inhibited human and dog chymases, but not rabbit ACE. NK3201 suppressed the Ang I-induced vascular contraction in isolated dog arteries in the presence of an ACE inhibitor, and the IC50 value of chymostatin and NK3201 in dog artery was 320 nM. In dog, the concentration of NK3201 in blood was about 10 microM at 24 h after oral administration of the drug (5 mg/kg). In the group treated with NK3201, each dog was administered orally 5 mg/kg per day from 5 days before to the day before the removal of the grafted veins. Each dog underwent right common carotid artery bypass grafting with the ipsilaterial external jugular vein. By 28 days after grafting, a significant vascular proliferation was observed in the grafted veins and the chymase activity was also increased significantly. Treatment with chymase inhibitor significantly suppressed the proliferation of the grafted veins and the increased chymase activity. In this study, we demonstrate for the first time that oral administration of a specific chymase inhibitor, NK3201, appears useful for preventing vascular proliferation.

Abstract
OBJECTIVES The great saphenous vein graft is known to be less patent than the internal thoracic artery graft. Recently, we reported that chymase-dependent angiotensin II formation plays an important role in the development of intimal hyperplasia in dog grafted veins. In this study we investigated the levels of angiotensin II-forming enzymes, angiotensin-converting enzyme, and chymase in human saphenous veins and internal thoracic arteries. METHODS The saphenous vein and internal thoracic artery specimens were obtained from coronary artery bypass grafts of patients during surgical procedures (saphenous vein, n = 16; internal thoracic artery, n = 16). Activities of angiotensin-converting enzyme and chymase were determined by using the extract from the saphenous vein or internal thoracic artery. Sections of the saphenous vein or internal thoracic artery were stained with van Gieson's elastin stain and were immunostained with anti-human chymase antibody. RESULTS The activities of angiotensin-converting enzyme in the saphenous vein and internal thoracic artery were 0.34 +/- 0.12 and 0.32 +/- 0.17 mU/mg protein, respectively, and the difference was not significant. The chymase activity in the saphenous vein was significantly higher than that in the internal thoracic artery (saphenous vein, 10.1 +/- 0.81 mU/mg protein; internal thoracic artery, 6.21 +/- 1.86 mU/mg protein). Chymase-positive cells in the saphenous vein were located in both the media and adventitia, and those in the internal thoracic artery were located only in the adventitia. The number of chymase-positive cells in the saphenous vein was about 2.6 times that in the internal thoracic artery. CONCLUSION The chymase activity, but not the angiotensin-converting enzyme activity, was significantly higher in the saphenous vein, suggesting that the high levels of chymase activity may be related to the poorer performance of the saphenous vein for use as a bypass conduit.

Abstract
Cilostazol prevents neointimal formation, but its mechanism has remained unclear. We investigated whether intimal formation in dog grafted veins is suppressed by cilostazol, and studied the effect of cilostazol on angiotensin II-forming enzymes. The external jugular vein was grafted to the carotid artery, and cilostazol (60 mg/kg/day) was administered orally. By 28 days after the surgery, the intimal cross-sectional area of the grafted vein was reduced to 16.7% by treatment of cilostazol, and the activities of angiotensin II-forming enzymes were suppressed significantly. The inhibitory effect of cilostazol in intimal formation may be dependent on inhibition of angiotensin II-forming enzymes.

Abstract
We investigated the levels of the angiotensin II-forming enzymes, chymase and angiotensin converting enzyme (ACE), in dog grafted veins, and studied the effect of an angiotensin II type 1 receptor antagonist, L-158,809, on vascular proliferation in the grafted veins. The right external jugular vein was grafted to the ipsilaterial carotid artery. In the group treated with L-158,809, the drug (10 mg/kg per day, p.o.) were administered orally from 7 days before the operation to 28 days after it, while the others were administrated placebo. In the placebo-treated group, the chymase activity in the grafted veins was increased about 10-fold and the ACE activity was doubled. The areas of intima and media were significantly increased in the grafted veins in the placebo-treated group. L-158,809 significantly reduced the intimal area of the grafted veins. An angiotensin II receptor antagonist, L-158,809, prevented the vascular proliferation in the grafted veins, and the development of the proliferation may depend on activation of local angiotensin II formation.

Abstract
We investigated the effect of a chymase inhibitor Suc-Val-Pro-Phe(P)(OPh)(2) on the proliferation of the grafted vein in dog. By 28 days after the operation, the mean intimal area of the grafted vein in the placebo group was 3.24+/-0.32 mm(2). The intimal area of the grafted vein in the chymase inhibitor-treated group was reduced to 63.9%. In the placebo group, the activities of chymase and angiotensin-converting enzyme in grafted vein were significantly increased 15- and 2-fold, respectively. In the chymase inhibitor-treated group, chymase activity in the grafted veins was decreased significantly. These findings suggest that inhibition of chymase appears useful for preventing vascular proliferation.

Abstract
We report here a case of active infective endocarditis caused by Methicilin-Resistant Staphylococcus aureus (MRSA). A 24-year-old woman was admitted to the Osaka Medical Collage Hospital with continuous fever. After admission, MRSA was detected by blood culture and chemotherapy with Vancomycin was started. However, after 1 week, her condition had not improved. Moreover, a pedicled vegetation on the posterior wall of the left atrium and mitral regurgitation due to prolapse of the anterior leaflet were revealed by transesophageal echocardiography. The vegetation grew to about 2 cm in diameter and prolapsed into the left ventricle during diastole. We performed an early operation although the infection was still active due to its rapid growth and the risk of embolism. There was a large pedicled vegetation on the posterior wall of the left atrium as shown by preoperative echocardiography, but the mitral valve appeared to be intact. Therefore, the vegetation was completely removed and the mitral annulus was plicated by Kay's method to treat the associated mitral regurgitation. Postoperatively, we administered VCM 2 g/day for 24 days. The course was uneventful. The patient was discharged from the hospital on the 31st postoperative day.

Abstract
We reported a case of ankylosing spondylitis who successfully underwent coronary artery bypass grafting (CABG) for unstable angina pectoris. A 67-year-old man was admitted with symptom of anginal pain. Selective coronary angiography revealed coronary artery stenoses; 90% in seg 6, 90% in seg 11, proximal 75%, distal 90% in seg 3, 99% in 4 PD and 99% with delay in 4 AV. The left internal thoracic artery was anastomosed to seg 7 and saphenous vein (SVG) to PL-2, PL-1 sequentially, and another SVG to 4 PD. His postoperative course was uneventful. Cardiac lesions accompanied by ankylosing spondylitis are rare in Japan. Perioperative problems of these lesions therefore, are discussed.

Abstract
Three cases of the thoracic aortic rupture due to blunt trauma were successfully treated. All of the cases were young male motorcyclists. The chest X-ray on admission showed either a widened mediastinum or an apical extrapleural cap sign. Ruptures were confirmed by an enhanced CT clearly showing the presence of a psuedoaneurysm and a hematoma around the isthmus of the aorta. One of them was operated upon urgently and others in whom heparin could not be used because of associated injuries were operated upon electively two and three months after the traffic accident, respectively. In two of them, aneurysms were removed and replaced with dacron grafts and in the remaining one, the aneurysm was resected and repaired directly under the femoro-femoral bypass. Post-operative courses were uneventful. They discharged and are doing well after the treatment for associated injuries. In view of the high early mortality of aortic rupture, an early diagnosis and treatment is important. But in the case who has stable hemodynamics and contraindication for heparinization, a delayed operation may be recommended.
