Abstract
Borderline oxacillin-resistant Staphylococcus aureus (BORSA) are mecA-negative strains with oxacillin minimum inhibitor concentration (MIC) close to the resistance breakpoint of ≥ 4μg/mL. Instead of producing penicillin-binding protein with low affinity to methicillin (oxacillin) mediated by mecA gene as in methicillin-resistant S. aureus (MRSA), BORSA strains are characterised by the hyperproduction of β-lactamase enzymes, thus able to break down methicillin. Common laboratory methods to detect MRSA such as cefoxitin disk diffusion alone may fail to detect methicillin resistance due to BORSA. We report five cases of BORSA blood-stream infections in a university teaching hospital. All isolates were found to be susceptible to cefoxitin using disk diffusion, resistant to oxacillin using automated MIC method, and did not harbour mecA gene. All patients were suscessfully treated with anti-MRSA antibiotics, and removal of primary sources were done if identified. A more cost-effective method for screening and diagnosis of BORSA is needed in addition to cefoxitin disk diffusion test, in order to monitor the spread, and to enable routine detection and treatment of this pathogen.

Abstract
BACKGROUND As Canada and other high-income countries continue to welcome newcomers, we aimed to 1) understand newcomer parents' attitudes towards routine-childhood vaccinations (RCVs), and 2) identify barriers newcomer parents face when accessing RCVs in Alberta, Canada. METHODS Between July 6th-August 31st, 2022, we recruited participants from Alberta, Canada to participate in moderated focus group discussions. Inclusion criteria included parents who had lived in Canada for < 5 years with children < 18 years old. Focus groups were transcribed verbatim and analyzed using content and deductive thematic analysis. The capability opportunity motivation behaviour model was used as our conceptual framework. RESULTS Four virtual and three in-person focus groups were conducted with 47 participants. Overall, parents were motivated and willing to vaccinate their children but experienced several barriers related to their capability and opportunity to access RCVs. Five main themes emerged: 1) lack of reputable information about RCVs, 2) language barriers when looking for information and asking questions about RCVs, 3) lack of access to a primary care provider (PCP), 4) lack of affordable and convenient transportation options, and 5) due to the COVID-19 pandemic, lack of available vaccine appointments. Several minor themes were also identified and included barriers such as lack of 1) childcare, vaccine record sharing, PCP follow-up. CONCLUSIONS Our findings highlight that several barriers faced by newcomer families ultimately stem from issues related to accessing information about RCVs and the challenges families face once at vaccination clinics, highlighting opportunities for health systems to better support newcomers in accessing RCVs.

Abstract
Over the last two decades, only a handful of research have been conducted pertaining to
food safety in the aviation industry. The gap of knowledge in in-flight food safety
literature has long been silenced. Therefore, it was the objective of this study to conduct
preliminary screenings to evaluate the environmental quality of the service equipment
(GE), safety equipment (SE) and common facilities (CF) within the confinement of
commercial aeroplanes in Malaysia. A total of 112 swab samples (n = 112) were analyzed
to detect the prevalence of Escherichia coli, Vibrio, Salmonella and coliforms using
conventional microbiological methods. The qualitative aerobic mesophilic plate count
revealed that 99 (88.39%) and 13 (11.61%) were reported as positive and negative
samples, respectively. It was reported that all 17 samples taken from the long-haul flight
were positive, with 8 (9.14%), 4 (3.57%) and 5 (4.46%) samples belonging to the GE, SE,
and CF, respectively. Forty-five positive swab samples taken from medium-haul flight
sectors showed that 30 (26.79%), 8 (9.14%), 7 (6.25%) samples were that of the GE, SE,
and CF, respectively. Meanwhile, 19 (16.96%), 8 (9.14%), and 10 (8.93%) of the shorthaul flights samples were that of the GE, SE, and CF, respectively. It was therefore
concluded that GE, SE and CF were reported at 57 (50.89%), 20 (17.86%) and 22
(19.64%), respectively. In view of the large numbers and high percentages of positive
sample results, it is our opinion that the cleaning, sanitizing and disinfecting procedures of
the galley equipment, safety equipment and common facilities are revisited. The assurance
in conformance to the hazard analysis and critical control points (HACCP) management
system may enhance the safety and reliability of all stakeholders especially the flight
attendants who are the final custodians of the environmental hygiene and that of
themselves.

Abstract
Abstract
Background
Hypertrophic obstructive cardiomyopathy (obstructive HCM) is an autosomal dominant congenital disease characterized by obstruction of the left ventricular outflow tract with asymmetric septal hypertrophy. Obstructive HCM is predispose to the appearance of malignant ventricular arrhythmias, leading to syncope or sudden death.
Case Description
A 25-years-old male patient came to the hospital with chief complaint intolerance activity and previous syncope, without history of sudden cardiac death in his family member. ECG showed sinus rhytm with left axis deviation and left ventricular hypertrophy. Chest x ray showed cardiomegaly. The echocardiography showed asymmetric septal hypertrophy (septal/posterior wall thickness ratio 1.31), left atrium dilatation (LAVi 94.2 mL/m2), SAM and mild mitral regurgitation, mild aortic regurgitation, hyperdynamic ejection fraction (79%) with lower longitudinal strain values in basal and mid ventricular septal segment, grade I diastolic dysfunction, resting LVOT gradient 19.53 mmHg , provoked LVOT gradient 47.31 mmHg.
Discussion
Non-invasive treatment was given due to LVOT gradient below 50 mmHg. The patient prescribed diltiazem 100mg once daily and recommended clinical evaluation follow-up every year or any worsening of symptoms. The other family member suggested for familial screening echocardiography.

Abstract
Abstract
Background
Percutaneous Transvenous Mitral Commissurotomy (PTMC) has become the treatment of choice for patients with mitral stenosis. PTMC guided by three-dimensional Transesophageal Echocardiography (3D-TEE) promise of greater safety and efficacy.
Case Summary
We report a 29-year-old woman who came to our outpatient clinic with shortness of breath as a chief complaint for the past three months. ECG depicted sinus rhythm. Transthoracic Echocardiography (TTE) and 3D-TEE showed severe mitral stenosis with MVA planimetry: 0.8 cm2, MV mean PG 12 mmHg, MV PHT 403 ms, Wilkins score was 4 and no thrombus was found. Therefore, we decided to do PTMC. We successfully done the antegrade transseptal puncture by fluoroscopy guided by two-dimensional (2D) TEE . Then, we used Inoue-balloon catheter No. 24 to dilate the mitral valve. Afterthat, we did 3D-TEE evaluation of the mitral valve area and it showed a significant improvement, with MVA 3D planimetry: 2.0 cm2 and MV mean PG: 4 mmHg and we found moderate mitral regurgitation (MR VC 0.4 cm, MR PISA: 0.3 cm), so we decided to end the procedure.
Discussion
In this case, the PTMC procedure was carried with 2D and 3D-TEE guiding, where process run more easily because interventionist can ensure the targeted site during transeptal puncture, navigation to the mitral valve and post inflation inspection. 3D-TEE guiding can also directly ensure the success of PTMC in real time by evaluating the MVA planimetry (pre and post PTMC) and the mitral regurgitation.

Abstract
Abstract
Background
Ventricular Septal Defect (VSD) is the most common congenital heart defect with incidence rate about 50% of all case in children. VSD is often followed by weakness of the wall in the sinus of Valsalva causing aneurysms, where 30-50% of cases of aneurysms in the sinus of Valsalva is associated with VSD. Congenital heart defects also increased risk factors for infective endocarditis (IE) with the risk of infection 15-140 times greater than the general population.
Case Description
A 7-year-old boy was reported with fever and shortness of breath, echocardiography examination showed subaortic VSD, ruptured sinus of Valsalva, multiple vegetation on left ventricular outflow tract, right coronary cusp, and right ventricle, moderate aortic, pulmonal and tricuspid regurgitation with mild pulmonal hypertension. Although there was no growth of bacteria from blood culture but result from kidney ultrasound showed sign of glomerulonephritis, suggesting additional findings in Duke criteria. The patient was treated with broad spectrum antibiotic and heart failure drugs. Then, Heart Team decided to refer the patient to Cardiac Center Harapan Kita for evacuating vegetations and repairing congenital heart defect.
Discussion
Infective endocarditis is one of the most arduous complication that must be treated immediately in patients with VSD. Besides reducing the symptoms that arise from heart defects, the clinicians also have to stop the process of infection. Adequate antibiotics and immediate surgery are the best strategy to evacuate the focus of infection as well as to repair congenital defects.

Abstract
Abstract
Background
Wellens’ syndrome is a syndrome characterized by biphasic (type A) or deeply inverted T-wave (type B) in the anterior lead, without Q-waves and significant ST elevation, no loss of precordial R-wave progression, normal to minimally elevated cardiac enzymes, and a history of angina.
Case Summary
A 37-years-old male patient was admitted to the emergency department with the chief complaint of typical chest pain lasting for about 1 h. He had type 2 diabetes and a history of smoking. First ECG showed non-specific ST-T changes in the lateral lead. On ECG which was taken two hours later in the pain-free period, deeply inverted T waves were seen in the lead V2 and V3. Troponin I was found as 0.25 ng/mL. The patient was admitted to CVCU and brought to the angiography laboratory next day. A 90%-99% critical proximal LAD occlusion was observed. PCI was successfully performed with drug-eluting stent implantation and good restoration of LAD flow. He was discharged from the hospital on the following day without any complication after coronary intervention.
Discussion
Pseudonormalisation of T wave in pain period could be misinterpreted as normal ECG and could delay coronary angiography and revascularization. We should aware if a patient with typical chest pain came with normal or non-specific ECG changes. Evaluation of ECG in the pain-free period is crucial and leads to the best decision in managing the patient with this syndrome.

Abstract
Background
Covid-19 is an infectious disease caused by a newly discovered coronavirus that caused acute severe respiratory syndrome and other complication. Many cardiac complication already occurred such as carditis and acute heart failure. PVC bigeminy is a new complication that we found in our post covid-19 patient.
Case Summary
A 31-years-old female patient admitted to the outpatient department with chief complaint palpitation with chest discomfort in the past 1 month with a history covid-19 infection 3 months ago with prolong covid infection for 2 months. ECG showed sinus rhythm and bigeminy PVC with PVC LBBB morphology left inferior axis and transition zone in V4. The patient planned to do Electrophysiology study and ablation. From the EP study we found 2 type of PVC, both of the PVC have LBBB morphology with left inferior axis and transitional zone in V4. The first PVC had 42ms earliest activation time and the second PVC had 48ms earliest activation. We do ablation with non irrigating catheter on the first PVC but the PVC still remain. Then try with irrigating catheter and do the ablation. After the ablation the PVC already vanished and the ablation was successful.
Discussion
PVC bigeminy post covid-19 infection is a rare complication in covid-19 patient. PVC bigeminy cause several complain from palpitation, chest discomfort, and shortness of breath. Ablation is one of the best way to treat PVC bigeminy patient with symptoms and in the patient the ablation was successful.

Abstract
Background
Heparin-induced thrombocytopenia (HIT) is a serious adverse drug reaction that increases patient’s risk of developing venous or arterial thromboembolism, which maybe life-threatening. The frequency varies from 0.5% to 5%, depending on population studies. This condition will worsen especially in patients with deep vein thrombosis.
Case
A 52 years old woman was reported swelling and decreased saturation of the lower extremities, with a history of Heparin therapy for 5 days before being referred to Haji Adam Malik Hospital Medan. Platelet count on admission day was 225.000/µl but dropped into 64.000/µl in the 7th post heparin treatment day. Doppler examination showed multiple thrombosis in deep femoral vein and and sign of stenosis peripheral artery. Echocardiography showed intracardiac thrombus without sign of acute pulmonary embolism. Two days after discontinuation of heparin, the platelet still tend to be low but in the next days, its count increases to within normal range. Due to the high risk of embolism, it was decided to place a vena cava filter prior to surgery for thrombus evacuation.
Discussion
This case demonstrates several interesting aspects of HIT, including thrombotic complication, limitation tools to support diagnosis of HIT, how to prepare this patient into surgical management, and the last is placing a IVCF prior to surgical thrombus evacuation and thrombectomy to reduce the risk of thromboemboli before surgical treatment. This is the first time procedure in Medan for placing a vena cava filter in a DVT patients who have contraindication to heparin administration.

Abstract
Abstract
Background and Aims
Right ventricle systolic dysfunction develop prior to the onset of clinical systemic congestion; thus, early detection is beneficial for both diagnostic and therapeutic value. We aim to asses changes of Right Ventricular Global Longitudinal Strain (RVGLS) in rheumatic mitral valve disease, and assess correlation between Right Ventricular Systolic Pressure (RVSP) and RVGLS before and after intervention.
Methods and Results
Our study consisted of 21 patients with an established diagnosis of significant MS or MR and normal RV function, who were admitted for either Balloon Mitral Valvulotomy (BMV) or Mitral Valve Replacement (MVR). 2D echocardiography and measurement of RVGLS was obtained from RV-focused A4CH view. Patients were divided into 2 groups: (1) significant MS consists of 11 patients, (2) significant MR consists of 10 patients. Prior to intervention, MS group had significantly lower RVGLS compared to MR group (-11.64 vs. -18.29; p = 0.001). After MVR, the RVGLS of MS group was significantly increased compared to MR group (MS -11.64 to -15.59, p = 0.001 vs. MR -18.29 to -19.39, p = 0.069). Both MS and MR groups showed significant negative correlation between RVSP and RVGLS before and after intervention (r=-0.642; p = 0.002; r=-0.670; p = 0.001).
Conclusion
Pre-intervention with a background normal RV function, RVGLS was impaired significantly in MS group compared to MR group. Post intervention RVGLS improved significantly in MS group compared to MR group. Both groups showed significant negative correlation between RVSP and RVGLS before and after intervention.

Abstract
Abstract
Background
Hypertrophic obstructive cardiomyopathy (obstructive HCM) is an autosomal dominant congenital disease characterized by obstruction of the left ventricular outflow tract with asymmetric septal hypertrophy. Obstructive HCM is predispose to the appearance of malignant ventricular arrhythmias, leading to syncope or sudden death.
Case Description
A 25-years-old male patient came to the hospital with chief complaint intolerance activity and previous syncope, without history of sudden cardiac death in his family member. ECG showed sinus rhytm with left axis deviation and left ventricular hypertrophy. Chest x ray showed cardiomegaly. The echocardiography showed asymmetric septal hypertrophy (septal/posterior wall thickness ratio 1.31), left atrium dilatation (LAVi 94.2 mL/m2), SAM and mild mitral regurgitation, mild aortic regurgitation, hyperdynamic ejection fraction (79%) with lower longitudinal strain values in basal and mid ventricular septal segment, grade I diastolic dysfunction, resting LVOT gradient 19.53 mmHg , provoked LVOT gradient 47.31 mmHg.
Discussion
Non-invasive treatment was given due to LVOT gradient below 50 mmHg. The patient prescribed diltiazem 100mg once daily and recommended clinical evaluation follow-up every year or any worsening of symptoms. The other family member suggested for familial screening echocardiography.

Abstract
Abstract
Background
Percutaneous Transvenous Mitral Commissurotomy (PTMC) has become the treatment of choice for patients with mitral stenosis. PTMC guided by three-dimensional Transesophageal Echocardiography (3D-TEE) promise of greater safety and efficacy.
Case Summary
We report a 29-year-old woman who came to our outpatient clinic with shortness of breath as a chief complaint for the past three months. ECG depicted sinus rhythm. Transthoracic Echocardiography (TTE) and 3D-TEE showed severe mitral stenosis with MVA planimetry: 0.8 cm2, MV mean PG 12 mmHg, MV PHT 403 ms, Wilkins score was 4 and no thrombus was found. Therefore, we decided to do PTMC. We successfully done the antegrade transseptal puncture by fluoroscopy guided by two-dimensional (2D) TEE . Then, we used Inoue-balloon catheter No. 24 to dilate the mitral valve. Afterthat, we did 3D-TEE evaluation of the mitral valve area and it showed a significant improvement, with MVA 3D planimetry: 2.0 cm2 and MV mean PG: 4 mmHg and we found moderate mitral regurgitation (MR VC 0.4 cm, MR PISA: 0.3 cm), so we decided to end the procedure.
Discussion
In this case, the PTMC procedure was carried with 2D and 3D-TEE guiding, where process run more easily because interventionist can ensure the targeted site during transeptal puncture, navigation to the mitral valve and post inflation inspection. 3D-TEE guiding can also directly ensure the success of PTMC in real time by evaluating the MVA planimetry (pre and post PTMC) and the mitral regurgitation.

Abstract
Abstract
Background
Wellens’ syndrome is a syndrome characterized by biphasic (type A) or deeply inverted T-wave (type B) in the anterior lead, without Q-waves and significant ST elevation, no loss of precordial R-wave progression, normal to minimally elevated cardiac enzymes, and a history of angina.
Case Summary
A 37-years-old male patient was admitted to the emergency department with the chief complaint of typical chest pain lasting for about 1 h. He had type 2 diabetes and a history of smoking. First ECG showed non-specific ST-T changes in the lateral lead. On ECG which was taken two hours later in the pain-free period, deeply inverted T waves were seen in the lead V2 and V3. Troponin I was found as 0.25 ng/mL. The patient was admitted to CVCU and brought to the angiography laboratory next day. A 90%-99% critical proximal LAD occlusion was observed. PCI was successfully performed with drug-eluting stent implantation and good restoration of LAD flow. He was discharged from the hospital on the following day without any complication after coronary intervention.
Discussion
Pseudonormalisation of T wave in pain period could be misinterpreted as normal ECG and could delay coronary angiography and revascularization. We should aware if a patient with typical chest pain came with normal or non-specific ECG changes. Evaluation of ECG in the pain-free period is crucial and leads to the best decision in managing the patient with this syndrome.

Abstract
Abstract
Introduction
Atrial fibrillation (AF), the most common cardiac arrhythmia, promotes prothrombotic responses particularly in the distal part of the left atrial appendage (LAA) characterized by reduced flow and low shear stress. AF occurrence and duration are closely associated with endothelial dysfunction and left atrium remodeling.
The contribution of coagulation factors thrombin and factor Xa (FXa) to LA remodeling remains poorly studied. This study investigated whether thrombin and FXa promote endothelial dysfunction and profibrotic and prothrombotic responses in the distal and proximal parts of the LAA. Since SGLT2 inhibitors have shown pronounced cardiac protection, the contribution of SGLT2 was examined.
Methods
LAAs were harvested from porcine hearts. Proximal (low stasis, high shear) and distal (high stasis, low shear) parts were cut and incubated with a coagulation factor (thrombin or FXa). Left atrial endothelial cells (AECs) were collected enzymatically, cultured and used at passage 1. The level of oxidative stress was assessed using the redox-sensitive probe dihydroethidium (DHE), fibrosis by Sirius red histological staining, senescence-associated β-galactosidase (SA-β-gal) activity using X-gal staining in tissues and the fluorogenic substrate C12FDG and flow cytometry in cells. The expression of target proteins was detected by immunofluorescence staining and Western blot analysis.
Results
The distal part of LAA displayed higher levels of oxidative stress in the endothelium and the atrial wall than the proximal part. SA-β-gal activity, ICAM-1, VCAM-1, and MMP-9 staining was more pronounced in the endothelium of the distal part compared to the proximal part whereas eNOS staining was decreased. The distal LAA wall showed higher levels of fibrosis. Western blot analysis showed higher expression levels of tissue factor (TF), VCAM-1, MCP-1, MMP-9, TGF-β and SGLT-2 in the distal part compared to the proximal one. Both thrombin and FXa increased these signals to a greater extent in the distal part of the LAA whereas the eNOS expression level was decreased. Exposure of AECs to either thrombin or FXa induced a pro-oxidant response and increased the expression level of ICAM-1, TGF-β, MMP-2, MMP-9, SGLT1 and SGLT-2. Thrombin promoted SA-β-gal activity in AECs. The selective SGLT-2 inhibitor empagliflozin and the dual SGLT1/2 inhibitor sotagliflozin prevented the pro-oxidant response and SA-β-gal activity in response to thrombin.
Conclusion
Thus, the distal part of the LAA is prematurely affected by endothelial dysfunction and senescence associated with a pro-oxidant, pro-remodeling and pro-inflammatory response that is further increased by thrombin and FXa. Hence, the coagulation cascade appears to prematurely promote atrial endothelium and wall dysfunction predominantly in areas at risk that may pave the way to thrombus formation. The findings also suggest a potential protective effect of SGLT1 and/or SGLT2 inhibition on atrial dysfunction.

Abstract
Salmonellosis infection caused by Salmonella bacteria is a public endemic problem in
Malaysia with long-term morbidity and mortality effects. Thus, this study aimed to
explore the antipathogenic activity of natural extracts from Mangifera odorata against two
Salmonella species causing Salmonellosis. The extracts were derived from peel, flesh, and
kernel seed of M. odorata. The inhibition performance of the extracts against both
Salmonella enterica serovar Typhimurium and Salmonella enterica serovar Enteritidis
bacteria were subsequently tested by using a bioassay-guided fractionation method.
Results showed that the extracts derived from the kernel seed had the highest inhibition
percentage of 83-90% against the Salmonellosis infection, followed by the peel with an
inhibition of 61-67%, and lastly the flesh with an inhibition of 53-69%. The inhibition
activities of hexane extracted flesh (FCH), methanol extracted peel (PCM), and methanol
treated kernel seed (KTM) against S. enterica ser. Typhimurium bacteria were 59, 67 and
83%, respectively. Furthermore, the S. enterica ser. Enteritidis bacteria were found to be
highly susceptible against the methanol extracted kernel seed (KCM), followed by the
hexane extracted peel (PCH) and flesh (FTH) with the inhibition percentage of 90, 69 and
59%, respectively. The highly active anti-Salmonellosis performance of M. odorata
extracts was attributed to its intrinsically high total phenolics content at 8-10 g GAE/g
extract, high ferric reducing antioxidant power value (FRAP) at 18-22 g Fe2+/g extract and
excellent scavenging activity with the inhibition performance ranges between 86% and
90%. This study revealed the antipathogenic activity of methanol extracts of M. odorata
kernel seed inhibited the growth of both S. enterica ser. Typhimurium and S. enterica ser.
Enteritidis bacteria. This study also discovered the prophylactic property of natural
compounds in M. odorata kernel seed extracts and could be used as an anti-Salmonellosis
agent. In the near future, M. odorata can be developed as an innovative functional food
source for specific groups that are vulnerable to Salmonellosis

Abstract
We present a specific near-field configuration where an electrostatic force gradient is found to strongly enhance the optomechanical driving of an atomic force microscope cantilever sensor. It is shown that incident photons generate a photothermal effect that couples with electrostatic fields even at tip-surface separations as large as several wavelengths, dominating the cantilever dynamics. The effect is the result of resonant phenomena where the photothermal-induced parametric driving acts conjointly (or against, depending on electric field direction) with a photovoltage generation in the cantilever. The results are achieved experimentally in an atomic force microscope operating in vacuum and explained theoretically through numerical simulations of the equation of motion of the cantilever. Intrinsic electrostatic effects arising from the electronic work-function difference of tip and surface are also highlighted. The findings are readily relevant for other optomicromechanical systems where electrostatic force gradients can be implemented.

Abstract
Reduced susceptibility in Burkholderia pseudomallei during carbapenem therapy may lead to treatment failure. We isolated a clinical strain that had developed reduced susceptibility to carbapenems while on treatment. After reviewing the patient's clinical notes, the initial isolate (BUPS01/14) was exposed to carbapenem in vitro to mimic the clinical scenario. The stability of susceptibility of the carbapenem-exposed strain (BUPS01/14R) was examined by serial subculture in antibiotic-free broth. Biochemical and morphological comparison was performed by the VITEK® system and electron microscopy. MICs increased 32-fold following carbapenem exposure and became stable in the antibiotic-free environment. On electron microscopic examination, the BUPS01/14R cells were smoother and less wrinkled compared to BUPS01/14 cells. This report highlights a potential anti-melioidosis treatment failure due to the emergence of resistance while on carbapenem monotherapy. Further study of this strain is necessary to understand the mechanism of resistance at a molecular level.

Abstract
Endometriosis is a condition where there are functional endometrial glands and stroma in sites other than uterine mucosa. It is a unique condition which is benign but has a tendency of invasion and extension locally. Scar endometriosis is a rare entity where there is presence and proliferation of endometrial gland and stroma in the scar of the previous surgery. It is estimated to be only 0.03 to 0.15% of all cases of endometriosis. Because of its deceptive nature and lack of specific diagnostic tools, scar endometriosis is often difficult to diagnose. It is also a challenge for the clinicians as this condition is difficult to treat because it is nonresponsive to hormonal treatment and excision is often the only effective treatment. Here we present two cases of scar endometriosis that we have encountered in BIRDEM general hospital, Dhaka, Bangladesh in last five years.

Abstract
Abstract
Introduction
Ageing is associated with the appearance of endothelial senescence promoting endothelial dysfunction and, ultimately, cardiovascular events. Circulating microvesicles (MVs) of patients with acute coronary syndrome promoted premature endothelial senescence by stimulating the local angiotensin system. Omega 3 PUFAs have been shown to reduce the risk of cardiovascular disease in patients at high risk.
Purpose
This study investigated whether a 7-day intake of the omega 3 formulation EPA:DHA 6:1 by rats affects the level of MVs released by spleen-derived cultured leukocytes as well as their ability to promote premature senescence in target endothelial cells (ECs), and, if so, to clarify the underlying mechanism.
Methods
Middle-aged male Wistar rats (M, 48-week old) received 500 mg/kg/d of either EPA:DHA 6:1, EPA:DHA 1:1, or vehicle (CTL) for 7 days. Thereafter, spleen-derived leukocytes, a rich source of MVs, were prepared and cultured for 24 h. Cultured ECs were prepared from porcine coronary arteries. Senescence-associated β-galactosidase activity (SA-β-gal) was assessed by C12FDG, protein expression level by Western blot analysis, oxidative stress by dihydroethidium using confocal microscopy, and procoagulant MVs by prothrombinase assay. Spleen-derived leukocytes from untreated young (Y, 12-week) and old (O, 72-week) rats were also studied.
Results
Shedding of MVs by spleen-derived leukocytes significantly increased with increasing age. Incubation of ECs with leukocyte-derived MVs (10 nM Phtd Ser eq.) from M and O but not those from Y induced premature senescence after 48 h. The stimulatory effect of M-MVs was prevented by losartan and associated with oxidative stress. M-MVs induced an upregulation of senescence markers (p16, p21, p53), pro-atherothrombotic markers (VCAM-1, ICAM-1, tissue factor), the pro-inflammatory marker cyclooxygenase-2 (COX-2) but not COX-1, and of the angiotensin system (angiotensin-converting enzyme and type 1 angiotensin receptor), whereas endothelial NO synthase was down-regulated. A one-week intake of EPA:DHA 1:1 and 6:1 by M rats decreased the leukocyte-derived MVs shedding by about 14% and 24%, and EPA:DHA 6:1 reduced their ability to induce ECs senescence by 38%. The stimulatory effect of M-MVs on the expression of target proteins was also observed with those from the EPA:DHA 1:1 but not with those from the 6:1 group.
Conclusion
These findings indicate that ingestion of EPA:DHA 6:1 by middle-aged rats reduces not only the shedding of MVs by spleen-derived leukocytes but also their ability to induce pro-senescent, pro-thrombotic and pro-inflammatory responses in endothelial cells most likely by decreasing the local angiotensin system. They further suggest that EPA:DHA 6:1 may help to delay ageing-related endothelial dysfunction.

Abstract
Abstract
Introduction
Circulating microparticles (MPs) from patients with coronary artery diseases (CAD) have been shown to promote endothelial senescence and dysfunction involving the pro-oxidant local angiotensin system. Sodium-glucose cotransporters (SGLTs)2 inhibitors decreased the risk of cardiovascular disease in patients with type 2 diabetes and this effect appears to be independent of glycemic control. Moreover, high glucose and H2O2 have been shown to cause a redox-sensitive upregulation of SGLT1 and 2 in coronary artery endothelial cells (ECs).
Aim
Therefore, this study examined whether angiotensin II (Ang II, a potent NADPH oxidase-dependent inducer of oxidative stress) and CAD MPs stimulate SGLT1 and 2 expression in ECs, and assessed their role in the induction of endothelial dysfunction.
Methods
ECs were isolated from porcine coronary arteries. The protein expression level was assessed by Western blot analysis and immunocytochemical staining, oxidative stress using dihydroethidium staining, and senescence by senescence-associated beta-galactosidase activity (SA-beta-gal activity). Circulating CAD MPs were collected from blood samples of patients (61–79 year) with established cardiovascular disease.
Results
Control ECs expressed low levels of SGLT1 and SGLT2 proteins. Exposure of ECs to Ang II caused a time- and concentration-dependent increase in the protein level of SGLT1 and SGLT2 with a significant increase observed at concentrations as low as 10 nM. Exposure of ECs to CAD MPs (10 nM PhtdSer eq) from 3/5 patients increased the SGLT1 and SGLT2 protein level. An increased SGLT1 and SGLT2 immunofluorescence signal was also observed in response to Ang II and H2O2. Ang II increased the level of oxidative stress, SA-beta-gal activity, senescence markers (p53, p21 and p16), VCAM-1, MCP-1, tissue factor (TF) and the local angiotensin system (ACE, AT1R), and down-regulated that of eNOS. CAD MPs from 4/5 patients decreased eNOS level and from 5/5 patients increased VCAM-1 level. All the Ang II-induced effects were prevented by the dual SGLT1/2 inhibitor LX-4211 and the selective SGLT2 inhibitor, empagliflozin.
Conclusions
The present findings indicate that CAD MPs and Ang II upregulate the expression of SGLT1 and SGLT2 protein levels in ECs, and that they promote endothelial dysfunction. They further suggest that inhibition of SGLT1 and/or SGLT2 might be an attractive strategy to protect the arterial wall and, hence, the development of cardiovascular diseases.

Abstract
OBJECTIVES The aim of conducting this study is to measure health literacy (HL) and to investigate the factors associated with inadequate HL in a sample of outpatient clinics attendees (i.e. patients and companions) at Ain Shams University (ASU) Hospitals. STUDY DESIGN It is a cross-sectional study. METHODS The study was conducted on 805 attendees of the outpatient clinics at El-Demerdash University Hospital of ASU Hospitals. The Arabic versions of the Swedish Functional Health Literacy Scale and the European Health Literacy Survey Questionnaire-short version-were used to assess HL. The level of HL and factors influencing it were analyzed using correlation and binary logistic regression tests. RESULTS It was found that 81% of the participants had limited comprehensive health literacy (CHL; 34.3% inadequate and 46.7% problematic), while only 18.9% had sufficient CHL. Regarding functional health literacy (FHL), it was found that 84% had limited FHL (50.6% inadequate and 33.4% problematic), while only 16.1% had sufficient FHL. Females were more likely to have inadequate FHL. On the other hand, males, individuals with low educational levels, and attendees identified as patients as well as participants with inadequate FHL were more likely to have inadequate CHL. CONCLUSION The majority of our study population has limited HL. Extensive research is warranted to explore the extent of the problem on multi-institutional and national levels and to investigate more explanatory factors.

Abstract
Perivascular epithelioid cell tumours (pecomas) are rare mesenchymal tumours that are characterized by perivascular epithelioid cell differentiation and immunoreactivity to myogenic and melanocytic markers. These tumours can be classified as benign, uncertain malignant potential, or malignant. Because of the rarity of pecomas, their cause and clinical prognosis remain unclear. To the best of our knowledge, no reports in the literature describe a pecoma of the terminal ileum mesentery as a secondary tumour in an adult survivor of childhood embryonal rhabdomyosarcoma, let alone any childhood cancer. Here, we present the case of a 27-year-old man with a pecoma involving the mesentery of the terminal ileum. At the age of 5, he had been treated with a combination of chemotherapy and high-dose pelvic radiation therapy for embryonal rhabdomyosarcoma, most likely arising from the posterior bladder wall. During routine follow-up 22 years after this patient's initial treatment, computed tomography imaging revealed a mass within the terminal ileum mesentery. The tumour was successfully treated with surgical resection, and pathology examination determined the mass to be a pecoma with uncertain malignant potential. This first case of a pecoma of the terminal ileum mesentery arising within a high-dose radiation therapy field as a secondary tumour in an adult survivor of childhood cancer highlights the importance of screening and surveillance in high-risk childhood cancer survivors treated with high-dose radiation therapy. Further research to build a better understanding of this remarkably rare tumour is warranted.

Abstract
Solitons are proposed as the agents of plastic and viscoelastic deformation in aligned polyethylene. Interactions between straight, parallel molecules are mapped rigorously onto the Frenkel-Kontorova model. It is shown that these molecular interactions distribute an applied load between molecules, with a characteristic transfer length equal to the soliton width. Load transfer leads to the introduction of tensile and compressive solitons at the chain ends to mark the onset of plasticity at a well-defined yield stress, which is much less than the theoretical pull-out stress. Interaction energies between solitons and an equation of motion for solitons are derived. The equation of motion is based on Langevin dynamics and the fluctuation-dissipation theorem and it leads to the rigorous definition of an effective mass for solitons. It forms the basis of a soliton dynamics in direct analogy to dislocation dynamics. Close parallels are drawn between solitons in aligned polymers and dislocations in crystals, including the configurational force on a soliton. The origins of the strain rate and temperature dependencies of the viscoelastic behaviour are discussed in terms of the formation energy of solitons. A failure mechanism is proposed involving soliton condensation under a tensile load.

Abstract
AIM Ramadan fasting represents a major shift in meal timing and content for practicing Muslims. This study used continuous glucose monitoring (CGM) to assess changes in markers of glycaemic excursions during Ramadan fasting to investigate the short-term safety of this practice in different groups of patients with diabetes. METHODS A total of 63 subjects (56 with diabetes, seven healthy volunteers; 39 male, 24 female) had CGM performed during, before and after Ramadan fasting. Mean CGM curves were constructed for each group for these periods that were then used to calculate indicators of glucose control and excursions. Post hoc data analyses included comparisons of different medication categories (metformin/no medication, gliptin, sulphonylurea and insulin). Medication changes during Ramadan followed American Diabetes Association guidelines. RESULT Among patients with diabetes, there was a significant difference in mean CGM curve during Ramadan, with a slow fall during fasting hours followed by a rapid rise in glucose level after the sunset meal (iftar). The magnitude of this excursion was greatest in the insulin-treated group, followed by the sulphonylurea-treated group. Markers of control deteriorated in a small number (n=3) of patients. Overall, whether fasting or non-fasting, subjects showed no statistically significant changes in mean interstitial glucose (IG), mean amplitude of glycaemic excursion (MAGE), high and low blood glucose indices (HBGI/LBGI), and number of glucose excursions and rate of hypoglycaemia. CONCLUSION The main change in glycaemic control with Ramadan fasting in patients with diabetes is in the pattern of excursions. Ramadan fasting caused neither overall deterioration nor improvement in the majority of patients with good baseline glucose control.

Abstract
Absence status epilepticus (ASE) is a type of nonconvulsive status epilepticus in which continuous or recurrent generalized epileptiform discharges are associated with a varying grade of consciousness impairment. Absence status epilepticus may be obtained during progress of many epileptic syndromes, in several metabolic disturbances and related to use of several drugs. Absence status epilepticus is generally seen in childhood; rarely it can be seen in adulthood. In this paper, the case which has never diagnosed until now in spite of many absence seizures for years, applied for absence seizures to our clinic and diagnosed for juvenile absence epilepsy, has been discussed.

Abstract
Background. Obesity is a major health concern and is associated with metabolic syndrome (MetS) that increases the risk for cardiovascular disease (CVD). Since little is known about the relationships between MetS components and CVD in overweight/obese young Arab females, our study aimed at examining these relationships and further to explore the associations between connecting peptide (C-peptide) and insulin with these biomarkers. Subjects and Methods. In this cross-sectional study, 80 apparently healthy young Arab females were recruited and grouped by their body mass index (BMI) into normal-weight (GI) and overweight/obese (GII) groups. Results. The two groups significantly differed in BMI, waist circumference (WC) and values of biomarkers, namely, leptin, fasting insulin, uric acid (UA), insulin resistance (HOMA-IR), C-peptide, high-sensitivity C-reactive protein (hs-CRP), high-density lipoprotein cholesterol (HDL-C), systolic blood pressure (SBP), and diastolic blood pressure (DBP). C-peptide significantly correlated with WC, leptin, UA, and HDL-C and was predicted by three biomarkers; UA, WC and HDL-C. Whereas, insulin significantly correlated with only two biomarkers including leptin and DBP and was predicted by UA and DBP. Conclusions. The present study highlighted the association between MetS and CVD in young Arab females and the possible role of C-peptide in the prediction of CVD.

An understanding of common pathogens and their antibiotic sensitivity patterns is critical for proper management of sepsis in Emergency Department (ED). The goal of the study was to identify common organisms isolated from blood cultures of patients attended to ED and their antimicrobial susceptibility. Beginning from 2002, all cases of positive blood culture collected by the ED, Hospital Universiti Sains Malaysia (HUSM) were recorded and analysed. Over the period of eight years, we documented 995 cases of positive blood cultures. Of these samples, 549 (55.2%) were Gram-negative bacteria; 419 (42.1%) were Gram-positive bacteria; 10 (1.0%) were anaerobic organisms; 10 (1.0%) were fungus; and 7 (0.7%) cases were mixed organisms. Gram-negative bacteria were observed to develop more resistance to antimicrobial agents, especially those commonly used in an outpatient setting with less than 80% sensitivity to ampicillin, cotrimoxazole and ciprofloxacin. By contrast, there has been no marked change in the sensitivity trends of Gram-positive bacteria over the same period. In conclusion, ED physicians are more equipped to initiate empirical antimicrobial therapy especially when dealing with possibility of Gram-negative sepsis.

Abstract
This paper explores the design of computer-based systems that support the management of organisational knowledge. The information systems notions of databases and information architectures are extended to the search for a meaningful conceptual structure by which collective knowledge can be supported by existing information technologies. An "architecture" is presented where the key unit of analysis is human activity as proposed by the cultural–historical activity theory. This architecture has the richness of the activity theory philosophy and yet addresses the issues of practical implementation from both the technical and organisational perspectives. The paper articulates the architecture and also reports on a study where its effectiveness was evaluation by a target group. An implementation of the architecture is also introduced.

Abstract
The socio-cultural and economic contexts in developing countries influence the epidemiology or STIs and helps in making them an important public health priority. This study was carried out to explore the health care seeking pathway of the women suffering from RTls/STls. influence or major socio-demographic variables on treatment seeking pattern. This cross sectional study was carried out comprising or eight hundred reproductive age (15-49 years) women selected following a multistage sampling procedure. The information pertaining to health seeking behaviour were collected from them using a pre-designed pretested interview schedule. Quantum of RTIs/STIs in the study group was estimated and symptomatics were asked specially about time lag between appearance of symptoms and seeking acre; reason for not seeking care; outcome of treatment they have taken if any. Out of total 359 subjects with symptoms of RTls/STls only about one-third (37.3%) had sought treatment. Only a few (4.5%) had sought treatment within 1 month of appearance of symptoms. Considering it to be physiological about half of the subjects (45.3%) did not seek treatment. The treatment seeking pattern was highly associated with the level of education (p = 0.000). Reluctance in seeking treatment, delay in its initiation, prelerence for unqualified practitioners in first consultation and significant association between education and treatment seeking pattern emphasize BCC and service provision for control and prevention of RTls/STls.

Abstract
OBJECTIVE To assess the prevalence of hypertension in a low-income community in Karachi. METHODS Cross sectional survey, through multi-stage sampling of 857 adult subjects in 405 households was conducted between April and September 2002. RESULTS The overall prevalence of hypertension was 26% (95% C.I. 23, 29), the prevalence among males (34%) was higher than females (24%). The mean age of participants was 35 +/- 14 years, the prevalence of hypertension increased with age. Proportionately there were more cases of hypertension among male participants over 35 years of age as compared to female participants of the same age (p < or = 0.001). Fifty-eight percent of hypertensives were unaware of their hypertension. None of the hypertensive subjects who were aware of their condition had blood pressure under 140/90 mmHg. Stratified analysis revealed significant risk factors for hypertension. Hypertension was 1.7 (OR 95% C.I. 1.14, 2.42) times more common among males then females. Males were 1.7 (OR 95% C.I. 1.06, 2.6) times less likely to have been aware of their hypertension status. Age analysis revealed that the prevalence of hypertension increased with age and hypertensive subjects were 5.6 (OR 95% C.I. 3.9, 8.1) times more likely to be over 35 years of age. CONCLUSION There is a need to control hypertension and prevent its complications through effective community interventions. The survey results indicate high prevalence and poor control of hypertension in the community, but more research is required to understand the reasons behind this phenomena.

Abstract
Over the 33-day duration of the 1999 Haj in Saudi Arabia, we collected daily health status reports for 2070 Pakistani pilgrims over 13 years of age, 54% of whom had elected to receive influenza vaccine immediately before departing for the Haj. We calculated vaccine preventable outcome incidence as the difference in attack rates between vaccinated and unvaccinated persons. The incidences of vaccine preventable influenza-like illness (sore throat in combination with cough or fever of at least 38 degrees C), fever, and any symptom of upper respiratory infection were 22, 17, and 24 per 100 pilgrims per Haj. For every 100 persons who attended the Haj, 17 had a course of antibiotics and 23 had a course of nonprescription cold medication that was preventable with influenza vaccine use. Influenza leads to significant morbidity and medication use among Haj pilgrims. Vaccine against influenza should be considered for pilgrims before entry into Saudi Arabia.

Abstract
We conducted a seroepidemiological survey of zoonotic parasite infection in inhabitants of East Java, Indonesia. The subjects of the survey were 244 persons selected from visitors to Sidoarjo City Hospital in East Java between May 1992 and October 1993. Ninety-seven had diarrhea and the rest came to the hospital for routine check-ups. All serum samples were tested for antibodies against five zoonotic parasites: Toxoplasma gondii, Entamoeba histolytica, Toxocara canis. Angiostrongylus cantonensis, and Anisakis species. Tests used were enzyme-linked immunosorbent assays (ELISA), latex agglutination (LA) test, indirect fluorescence antibody (IFA) test, hemagglutination (HA) test, and gel diffusion precipitation (GDP) test. Some 64% of the subjects had antibodies to T. gondii. The prevalence of antibodies to E. histolytica varied from 2 to 15% depending on the test, but the true rate was probably the 7% or 8% obtained by the HA and IFA tests. The proportions of subjects with positive results were 63% for T. canis, 17% for A. cantonensis, and 11% for the Anisakis spp. The prevalence of antibodies to T. gondii and T. canis was lower in subjects aged 1 to 9 years than in older subjects, probably because the persons in this group had less time to be infected. Antibody titers to A. cantonensis and the Anisakis spp. were high in the juvenile group, perhaps because recent changes in eating habits have increased opportunities for infection.
