Currently, Resuscitative Endovascular Balloon Occlusion of the Aorta (REBOA) plays role in control of intraabdominal bleeding. Therefore, it is necessary to use several methods to confirm the position of the balloon precisely, such as fluoroscopy. But most hospitals in Thailand do not support fluoroscopic machine in ER. This study aimed to determine the intravascular length for placement REBOA and compare to the appropriate locations of external landmarks of the body.</p> <p><strong><u>Method</u></strong><strong>:</strong> Human cadaveric study, external anatomical (sternal notch, xyphoid process and umbilicus) and intravascular (left subclavian artery (LSA), celiac trunk (CT), lowest renal artery (LRA) and aortic bifurcation (AB)) landmarks from puncture sites. The landing zones were calculated with intravascular landmarks.</p> <p><strong><u>Results</u></strong><strong>:</strong> Twenty-two cadavers were analyzed. Mean external landmarks from right groin to umbilicus, xyphoid, sternal notchere 19.20, 32.26, 53.42 cm. and from left groin were 19.25, 32.62, 53.65 cm. The mean intravascular distance from right puncture site to AB, LRA, CT, LSA were 21.37, 30.47, 33.95, 55.97 cm. and from left puncture site were 20.69, 29.72, 32.87, 56.20 cm. There are statistically significant of clinical correlations between external and intravascular length of right groin - umbilicus with right puncture site - AB (p=0.0385) and right groin - sternal notch with right puncture site - LSA root (p=0.303).</p> <p><strong><u>Conclusion</u>:</strong> The use of external anatomical landmarks to estimate length of REBOA in Zone-1 and Zone-3 with evaluate the clinical response is safe to perform the procedure.</p> Panu Teeratakulpisarn, Phati Angkasith, Parichat Tanmit, Supatcha Prasertcharoensuk, Chaiyut Thanapaisal, Narongchai Wongkonkitsin Copyright (c) Fri, 16 Oct 2020 00:00:00 +0700 Continuous Quality Improvement of Clinical Practice Guideline for Management of Patients Undergoing Percutaneous Nephrolithotomy Under General Anesthesia in Srinagarind Hospital <p><strong><u>Background and Objective</u></strong><u>:</u> Percutaneous nephrolithotomy (PCNL) is a minimal invasive surgery for treatment of renal calculi. It may cause pleural cavity injury, i.e., pneumothorax, hydrothorax, or hemothorax (P/H/H), which mostly occurs in supracostal access of trocar puncture. The previous practice guideline requires that, for safety, endotracheal tube must be retained at the end of surgery in all patients undergoing PCNL with supracostal access leading to patient discomfort and agitation. They were extubated after pleural cavity injury was assessed using portable CXR at PACU. To reduce patient discomfort, we improved the guideline using PaO<sub>2</sub>/FiO<sub>2</sub> (P/F) ratio ≤ 300 mmHg as criteria to retain endotracheal tube in these patients. The objective of this study was to evaluate the efficacy of the new guideline.</p> <p><strong><u>Methods</u></strong><u>:</u> This was a prospective, descriptive study. We included all adults undergoing elective PCNL at Srinagarind hospital, Khon Kaen university between July 2017 and November 2018. We identified the incidence of endotracheal tube retaining and pleural cavity injury.</p> <p><strong><u>Results</u></strong><u>:</u> Forty-seven patients were included. There were 20 cases (42.6%) with supracostal access. Among supracostal patients, there were 9 cases (45%) with P/F ratio ≤ 300 mmHg who required endotracheal tube retaining with 2 cases (4.3%) complicated with hydrothorax and 3 cases (6.4%) with sepsis.</p> <p><strong><u>Conclusions</u></strong><u>:</u> The improved guideline using P/F ratio ≤ 300 mmHg as criteria to retain endotracheal tube in patients undergoing PCNL with supracostal access can reduce incidence of endotracheal tube retaining from 100% to 45% without complication. The incidences of pleural cavity injury and sepsis were 4.3% and 6.4%.</p> Wilawan Somdee, Sirirat Tribuddharat, Thepakorn Sathitkarnmanee, Wichien Sirithanaphol, Narin Plailaharn, Pakorn Kiatsopit, Ukrit Rompsaithong, Suthannee Simajareuk, Viriya Thincheelong, Khochakorn Palachewa Copyright (c) Fri, 16 Oct 2020 00:00:00 +0700 The Effect of Overnight Fasting on Stroke Volume Index Measured by Whole Body Impedance Cardiography <p><strong><u>Background and Objecitve</u></strong><u>: </u>Preoperative fasting is recommended to prevent pulmonary aspiration. Fasting induces hypovolemia. Intravenous fluid infusion is commonly given during anesthesia to minimize the risk of hypotension. However, intravenous fluid overload has been shown to deteriorate patient outcome. From previous literatures, the effect of preoperative fasting on intravascular volume is still inconclusive. There is no previous study that assesses intravascular volume status before and after fasting using the whole body impedance cardiography which is a non-invasive, practical and operator-independent. The reliability of whole body impedance cardiography is comparable to pulmonary artery thermodilution which is gold standard. In this study, we assessed stroke volume index (SVI) before and after fasting for 8 to 10 hours using whole body impedance cardiography.</p> <p><strong><u>Methods</u></strong><strong><u>:</u></strong> This is prospective observational study. We included volunteers with American society of anesthesiologists (ASA) physical status classification I–II with age between 18-65 years old. SVI and other hemodynamic parameters were measured before and after fasting using whole body impedance cardiography. The absolute change of hemodynamic parameters before and after fasting more than 10% indicated clinical significance. P value &lt; 0.05 indicates statistical significance.</p> <p><strong><u>Results</u></strong><strong><u>:</u></strong> Sixty-two volunteers were enrolled and completed the study. SVI before and after overnight fasting were 40.0±8.7 mL/m<sup>2</sup> and 37.7±8.2 mL/m<sup>2</sup>, respectively. SVI after fasting was decreased 5.5%. The percentage absolute change of SVI in individual volunteer was in a range between 3.1% to -17.0%. Twelve subjects (19.4%) have decreased in SVI. Stroke volume (SV), cardiac output (CO) and cardiac index (CI) were decreased 5.6%, 6.6% and 6.4%, respectively. All hemodynamic parameters except heart rate were statistically decreased after fasting (p-value &lt; 0.05) but the absolute change less than 10%.</p> <p><strong><u>Conclusion</u></strong><strong><u>:</u></strong> Overnight fasting does not clinically affect SVI measured by whole body impedance cardiography in healthy population. Some volunteers have significantly decreased in SVI after fasting and appropriate intravenous fluid therapy probably improves CO.</p> Sivaporn Termpornlert, Onrada Chuasuwan, Pornpatra Areeruk, Tanit Virankabutra Copyright (c) Fri, 16 Oct 2020 00:00:00 +0700 Accuracy of Multi-parametric Magnetic Resonance Imaging for Diagnosis of Prostate Cancer <p><strong><u>Objective</u></strong><u>:</u> To assess the diagnostic accuracy of magnetic resonance imaging (MRI) for prostate cancer with multiple parameters.</p> <p><strong><u>Methods</u></strong><u>:</u> Patients who underwent both MRI and transrectal ultrasound-guided biopsy from July 2012 to August 2014, were reviewed retrospectively.&nbsp; Multiple parameters were assessed to determine the accuracy of MRI for prostate cancer; the apparent diffusion coefficient (ADC), dynamic contrast enhanced MRI (DCE-MRI), and the Cho/cit and (Cho+creat)/cit ratios.&nbsp; The areas under the receiver operating characteristic curves (AUC) were used to evaluate the diagnostic accuracy of metabolic ratios.</p> <p><strong><u>Results</u></strong><u>:</u> Thirty-six lesions from 28 patients were analyzed.&nbsp; Malignant lesions at the peripheral zone showed significantly lower ADCs than benign lesions (p &lt; 0.01).&nbsp; If lesion size was 1 cm or larger, the (Cho+creat)/cit ratio was significantly higher (p &lt; 0.01).&nbsp; The ADCs had a high specificity of 87.5%, an accuracy of 77.8%, and AUC of 0.68.&nbsp; DCE-MRI had high specificity of 91.7%, accuracy of 83.3%, and an AUC 0.78. The Cho/cit ratios showed a high sensitivity of 91.7%, but low specificity of 54.2%.&nbsp; The greatest AUC was 0.85 when the DCE-MRI was combined with the Cho/cit ratio, giving an accuracy of 83.3%.&nbsp; No significant improvement was established, however, when all 3 parameters were combined together.</p> <p><strong><u>Conclusion</u></strong><u>:</u> DCE-MRI and ADC had greater diagnostic accuracy than MR spectroscopy (MRS).&nbsp; Combined parameters improved specificity for prostate cancer lesions.</p> Chalida Aphinives, Chayanon Chinporncharoenpong, Kulyada Somsap, Vallop Laopaiboon Copyright (c) Fri, 16 Oct 2020 00:00:00 +0700 Factors Affecting Distance of 6-Minute Walk Test in Post Cardiovascular Surgery Patients after Discharge at Queen Sirikit Heart Center of the Northeast <p><strong><u>Background and objective:</u></strong> The 6-minute walk test (6MWT) is a popular, practical and straightforward test that widely used to guide a cardiac rehabilitation program and assess exercise tolerance, therapeutic effect and prognosis. 6-minute walk distance (6MWD) varies with different factors.

The aberration results from a reciprocal translocation are creating a BCR-ABL fusion gene. There are two major forms of the BCR-ABL fusion gene, involving ABL exon 2, but including different exons of BCR gene. The transcript b3a2 and b2a2 codes for a p210 protein. Other fusion gene leads to the expression of an e1a2 transcript, which codes for a p190 protein. Its frequency varies in different populations but there are no data from northeastern Thailand. In this study we aimed to report BCR-ABL fusion transcript types in northeastern Thailand CML patients by Multiple Reverse Transcriptase-Polymerase Chain Reaction (Multiplex PCR).</p> <p><strong><u>Materials and Methods</u></strong> Retrospective descriptive and analytical study of all adult CML patients in Srinagarind and Khon Kaen hospitals, which is the main tertiary medical center in the northeastern region Thailand. Data has been collected from medical records for 3 years (January 2017 to January 2020).&nbsp; &nbsp;Peripheral blood or bone marrow samples were analyzed by multiplex PCR from 177 adult northeastern Thailand CML patients. Aim to identify BCR-ABL fusion transcript types in northeastern Thailand CML patients by Multiplex PCR.</p> <p><strong><u>Results</u></strong><strong><u>:</u></strong> All patients examined were positive for some type of BCR/ABL rearrangement. The majority of the patients (93.79%) expressed one of the p210 BCR-ABL transcripts, b3a2 and b2a2 transcript types were detected in 58.19% and 35.59% respectively. Co-expression of b3a2 (p210)/e1a2 (p230) was detected in 0.56%. The expression of an e1a2 transcript type, which codes for a p190 protein showed 4.52%. And 1.14% was detected in e19a2 transcript type. Co-expression of p210/p190 was not detected.</p> <p><strong><u>Conclusions</u></strong><strong><u>:</u></strong> Multiplex RT-PCR is useful and saves time in the detection of BCR-ABL fusion transcript types; the occurrence of these transcripts associated with CML can assist in prognosis and treatment of disease.</p> Kanokon Chootawiriyasakul, Kanchana Chansung Copyright (c) Fri, 16 Oct 2020 00:00:00 +0700 Effect of Captopril on Erectile Dysfunction and Sperm Quality in Hypertensive Rats <p><strong><u>Background and Objectives</u></strong>: Hypertension has been reported to be associated with erectile and testicular dysfunction.&nbsp; This study aimed to evaluate the role of the anti-hypertensive drug, captopril, on erectile and testicular function in L-NAME-induced hypertensive rats.</p> <p><strong><u>Methods</u></strong><strong>:</strong> Male Sprague-Dawley rats were divided into 3 groups including control group received tap water, L-NAME group received L-NAME at dose 40 mg/kg/day for five weeks and captopril group received L-NAME and captopril at dose 5 mg/kg/day for the last two weeks.

Upper and lower extremities motor impairments and level of disability were assessed by Fugl-Meyer assessment (FMA) and modified Rankin Scale (mRS), respectively. Spearman’s correlation coefficients were used to investigate the association between outcome measures. Differences were considered statistically significant at p&lt;0.05.</p> <p><strong><u>Result:</u></strong> The results showed moderate positive correlations between upper extremity motor impairments (FMA-UEs) and low-frequency power in normal units (LF (nu)) (r=0.622; p=0.02), and low-frequency to high- frequency power (LF/HF) ratio (r=0.561; p=0.04). Furthermore, there were strong negative correlations between level of disability and LF nu (r =-0.855; p&lt;0.001), and LF/HF ratio (r=-0.711; p=0.006).</p> <p><strong><u>Conclusion:</u></strong> HRV of chronic ischemic stroke is associated with upper extremity motor impairments and level of disability.</p> Natchaya Chondaen, Phannarai Plusiri, Sukunya Srisawad, Sujitra Meesribau, Olan Isariyapan, Phatiwat Chotimol, Duangnapa Roongpiboonsopit, Benjarat Sangthong, Waroonnapa Srisoparb Copyright (c) Fri, 16 Oct 2020 00:00:00 +0700 Survival Rate of Oral Cancer Patients after Diagnosis in Buriram Hospital, Buriram Province <p><strong><u>Background and Objective:</u></strong><strong> &nbsp;</strong>Oral cancer (OC) is one of the head and neck cancers. Nowadays, the OC trended to be increased, and there was no study about the survival rate of OC patients in Buriram province. Therefore, the objective of this study was to determine the survival rate of OC after diagnosis in Buriram hospital, Buriram province.</p> <p><strong><u>Methods:</u></strong> Data of patients with OC were retrieved from the Buriram hospital-based cancer registry. OC is an International Classification of Diseases for Oncology, 3<sup>rd</sup> edition; C00 – C06. Patients with OC who were histologically proved and admitted to the Buriram Hospital (2014-2018) and followed up until 2019 of 339 cases. Survival rate were estimated by the Kaplan-Meier method. We reported by median survival time and 95% confidence interval. Comparison group of survival rate were estimated by Log-rank test.</p> <p><strong><u>Result:</u></strong> Of 339 OC patients which follow-up time was 444 person-year, and died during the study were 261 cases, corresponding to mortality (Case-fatality) rate of 59.0 per 100 person-year. (95% CI; 52.1 - 66.6). The median survival of OC was 0.83 years (95% CI; 0.70 - 0.96). The overall survival experience of 1, 3 and 5 years were 43.9% (95% CI; 38.5 - 49.1), 25.0 % (95% CI; 20.2 - 30.0), and 14.8 % (95% CI; 10.0 - 20.4), respectively.</p> <p><strong><u>Conclusion:</u></strong> The 5-years survival rate of OC after diagnosis at Buriram hospital was low. Therefore, primary and secondary prevention are needed. Screening program for early detection are required for improving the survival rate. Including the factors affecting to OC need to be focus.</p> Sarawoot Nontasila, Supot Kamsa-ard, Raksak Amphaiphan, Natalie Rose Noisuwan, Thida Ratanawilaisak Copyright (c) Fri, 16 Oct 2020 00:00:00 +0700 Expression of Recombinant Peptide LcI from Bacillus amyloliquefaciens KKU14 and Test for Its Inhibition on Burkholderia pseudomallei <p><strong><u>Background and objective:</u></strong> <em>Burkholderia pseudomallei</em> is a pathogenic bacterium, causing melioidosis, a serious infectious disease. Currently, the best treatment is using antibiotic drugs. However, many clinical strains are now intrinsically resistant to almost all available antibiotic drugs. Previous study indicated that <em>Bacillus amyloliquefaciens</em> KKU14 strongly inhibits <em>B. pseudomallei</em>. In this study, antimicrobial peptide LcI of <em>B. amyloliquefaciens</em> KKU14 was cloned and expressed to test activity against <em>B. pseudomallei</em>.</p> <p><strong><u>Materials and Methods:</u></strong><strong> &nbsp;</strong>Antimicrobial peptide LcI was searched from GenPept database (NCBI) and amplified from genome of <em>B. amyloliquefaciens</em> KKU14 by PCR and cloned into different cloning vectors. &nbsp;The recombinant clones were induced and their activity against <em>B. pseudomallei</em> strain P37 were tested by agar well diffusion and in-gel overlay.</p> <p><strong><u>Results:</u></strong> The recombinant peptide was successfully cloned. However, the expression could be observed only in pQE31 vector. The expressed peptide has the size of approximately 10 kDa. Nevertheless, the recombinant clones exposed no antimicrobial activities against <em>B. pseudomallei</em> strain P37.</p> <p><strong><u>Conclusion:</u></strong> The recombinant peptide LcI cloned from <em>B. amyloliquefaciens</em> KKU14 does not inhibit <em>B. pseudomallei</em> strain P37 in this study. This might due to improper folding of the recombinant peptide, or the peptide that was responsible for inhibition of <em>B. pseudomallei</em> might be other peptides, or the inhibition effect might need synergistically work from several peptides together, which has to be further investigated.</p> Wajeeorn Ouancharee, Chotima Potisap, Rasana W Sermswan, Atcha Boonmee Copyright (c) Fri, 16 Oct 2020 00:00:00 +0700 Update on Mechanism of Insulin Resistance and New Trend of Drug Development <p>&nbsp;Insulin plays a crucial role in regulating the proper metabolic and energy balance. Once insulin signal transmissions are decreased, this can lead to a condition known as “insulin resistance”.</p> <p>Difference mediators, such as pro-inflammatory cytokines, free fatty acids, blood glucose and&nbsp; ROS level can increase the activity of kinases, i.e. several Protein kinase C (PKC) isoforms, c-Jun N-terminal kinases (JNK), Protein kinase A (PKA), Mammalian Target of Rapamycin (mTOR) and Mitogen-Activated Protein Kinase (MAPK), which affecting the signal of insulin receptors, IRS, and downstream-located effector molecules. Therefore, better understanding on the molecular mechanisms of these pathways is important for developing a more effective treatment of insulin resistance and associated diseases.</p> <p>This review summarizes the current knowledge on the mechanism of insulin resistance, the diseases associated with insulin resistance and biological effects of recent agents, which are developed for increasing insulin signaling, and are currently undergoing clinical trials.</p> Patcharin Singdam, Patchareewan Pannangpetch, Kampeebhorn Boonloh Copyright (c) Fri, 16 Oct 2020 00:00:00 +0700 Acute angle Closure Glaucoma <p>Acute angle-closure glaucoma is an ocular emergency that potentially leads to irreversible blindness if the treatment is delayed. The main etiology is the iridotrabecular contact, resulting in anterior chamber angle closure and inadequate drainage of aqueous humor hence the intraocular pressure (IOP) suddenly increases. Risk of angle closure is high among the elderly, women, Asian population and those with hyperopia. Diagnosis relies on history of symptoms resulting from the acute IOP rising and ocular examination demonstrating angle closure with anatomical risk factors. Patients usually present with acute severe painful blurred vision, ciliary injection, seeing rainbow halo around lights, nausea, vomiting and headache. Ocular examination showed high IOP, shallow anterior chamber, anterior lens position, closed anterior chamber angle, and occasionally, optic disc edema. Treatment consists of immediate IOP reduction, control of inflammation and reopen the angle by laser or lens extraction with goniosynechialysis. Serial gonioscopy is considered for the long-term angle monitoring. Trabeculectomy is performed in cases of uncontrolled IOP after reopening of the angle.</p> Sukhumal Thanapaisal, Pawasoot Supasai Copyright (c) Fri, 16 Oct 2020 00:00:00 +0700
