Introduction: Aortic stiffness is an independent predictor for cardiovascular event. If arteries lose their natural elasticity, systolic blood pressure become higher and dia­stolic blood pressure become lower. Method of evaluating arterial stiffness is aortic pulse wave velocity (PWV). Therefore, PWV has a potential application for screening vascular damage in large population.2 Recent reports have shown that PWV obtained by noninvasive automatic devices (i.e. tonometry, cuff pressure) is not only a marker of vascular damages, but also a prognostic predictor in patients with hypertension.3 The aim of this study is to investigate the correlation between PWV and systolic and diastolic blood pressure.
Methods : Male hypertensive patients, aged 40-60 years old who underwent Doppler Vascular were included in this study. The measurement of carotid-femoral PWV is made by dividing the distance (from the carotid point to the femoral point) by the so-called transit time (the time of travel of the foot of the wave over the distance). Hence, PWV = D (meters)/Dt (seconds). The correlation between PWV and systolic and diastolic blood pressure were analysed using linear regression test.
Results : A total 40 patients were included in this study. Those were significant correla­tion between PWV and systolic (R=0.473, p=0.002) and diastolic (R=0.454, p=0.003) blood pressure.
Conclusion : increasing PWV is linearly associated with systolic and diastolic blood pressure.

Abstrak
Pendahuluan: Kekakuan aorta adalah prediktor independen untuk kejadian kardiovaskular. Jika elastisitas alami arteri hilang, tekanan darah sistolik menjadi lebih tinggi dan tekanan darah diastolik menjadi lebih rendah. Metode evaluasi kekakuan arteri adalah kecepatan gelombang pulsasi (pulse wave velocity/PWV). Oleh karena itu, PWV dapat diterapkan untuk skrining kerusakan vaskular pada populasi besar.2 Laporan terbaru menunjukkan bahwa PWV yang diperoleh dengan perangkat otomatis non-invasif (yaitu tonometri, tekanan manset) tidak hanya merupakan penanda kerusakan vaskular, tetapi juga prediktor prognostik pada pasien dengan hipertensi.3 Tujuan dari penelitian ini adalah untuk mengetahui hubungan antara PWV dan tekanan darah sistolik dan diastolik.
Metode: Pasien pria dengan hipertensi, berusia 40-60 tahun yang menjalani Doppler Vascular dimasukkan dalam penelitian ini. Pengukuran PWV karotid-femoralis dilakukan dengan membagi jarak (dari titik karotid ke titik femoral) dengan waktu transit. Oleh karena itu, PWV = D (meter) / Dt (detik). Korelasi antara tekanan darah PWV dan sistolik dan diastolik dianalisis dengan menggunakan uji regresi linier.
Hasil: Sebanyak 40 pasien dimasukkan dalam penelitian ini. Itu adalah korelasi yang signifikan antara tekanan darah PWV dan sistolik (R = 0,473, p = 0,002) dan diastolik (R = 0,454, p = 0,003).
Kesimpulan: Peningkatan PWV berhubungan linear dengan tekanan darah sistolik dan diastolik.
PROSPECTS FOR APPLICATION OF COGENERATION TECHNOLOGIES IN MUNICIPAL ENERGY
Authors: Klimenko V.N. 
Published: September 2018

The article considers conditions and possibilities for installing cogeneration units (CUs) in district heating boiler houses. The main requirement to do it is the equality of the CUs’ heat capacity and the heat capacity of the boilers that are going to be replaced.
Because the fuel (natural gas) consumption increases due to such replacement, it is necessary to determine the conditions, taking into account the constant growth of energy carriers’ prices, under which the transition to cogeneration technologies in the heat supply system will be feasible, i.е. the project will make a profit and ensure the reasonable payback period. For this purpose, the relationships between the profitability of the project, the economic indicators of the equipment included in the cogeneration unit, and the price of energy carriers are suggested. An analysis performed with the help of these relationships showed that the cogeneration unit of the same thermal capacity as the boiler (or boilers), which is going to be replaced, in comparison with CU installed on the basis of a generating unit definitely requires an increase in fuel consumption, and the profit, determined as the difference between income from generated electricity sales and fuel purchase costs, becomes dependent on the prices of natural gas and electricity, as well as the cost-effectiveness of the equipment for cogeneration. With certain combinations of these parameters, the cogeneration unit, installed on the basis of heat generation, may not be profitable, but unprofitable. Moreover, as natural gas price increases and electricity tariff remains fixed, CUs, designed as profitable, may become unprofitable. These conditions are considered in the article. Relationships between the CU’s parameters and tariffs for the natural gas and electricity, which determine the area of profitable work of the cogeneration unit, are obtained. Given the current prices for energy carriers, the design of the CU based on the communal heat supply comes to the selection of the equipment that ensures the profitability of the installation that is sufficient for the recoupment of capital investments within 2-3 years. At the same time, the acceptable limits of the possible increase in the gas/electricity tariffs ratio should be determined.
The main conclusion: the cogeneration unit based on district heat supply with a positive economic effect can be installed only if certain economic and technological conditions, which must be taken into account when designing it, are observed.

OBJECTIVEHypoperfusion during carotid artery cross-clamping (CC) for carotid endarterectomy (CEA) may result in the major complication of perioperative stroke. Median nerve somatosensory evoked potential (MNSSEP) monitoring, which is an established method for the prediction of cerebral ischemia, has low sensitivity in detecting such hypoperfusion. In this study the authors sought to explore the limitations of MNSSEP monitoring compared to tibial nerve somatosensory evoked potential (TNSSEP) monitoring for the detection of CC-related hypoperfusion.METHODSThe authors retrospectively analyzed data from patients who underwent unilateral CEA with routine shunt use. All patients underwent preoperative magnetic resonance angiography and were monitored for intraoperative cerebral ischemia by using MNSSEP, TNSSEP, and carotid stump pressure during CC. First, the frequency of MNSSEP and TNSSEP changes during CC were analyzed. Subsequently, variables related to stump pressure were determined by using linear analysis and those related to each of the somatosensory evoked potential (SSEP) changes were determined by using logistic regression analysis.RESULTSA total of 94 patients (mean age 74 years) were included in the study. TNSSEP identified a greater number of SSEP changes during CC than MNSSEP (20.2% vs 11.7%; p < 0.05). Linear regression analysis demonstrated that hypoplasia of the contralateral proximal segment of the anterior cerebral artery (A1 hypoplasia) (p < 0.01) and hypoplasia of the ipsilateral precommunicating segment of the posterior cerebral artery (P1 hypoplasia) (p = 0.02) independently and negatively correlated with stump pressure. Both contralateral A1 hypoplasia (OR 26.25, 95% CI 4.52–152.51) and ipsilateral P1 hypoplasia (OR 8.75, 95% CI 1.83–41.94) were independently related to the TNSSEP changes. However, only ipsilateral P1 hypoplasia (OR 8.76, 95% CI 1.61–47.67) was independently related to MNSSEP changes.CONCLUSIONSTNSSEP monitoring appears to be superior to MNSSEP in detecting CC-related hypoperfusion. Correlation with stump pressure and SSEP changes indicates that TNSSEP, and not MNSSEP monitoring, is a reliable indicator of cerebral ischemia in the territory of the anterior cerebral artery.

Published: September 2018

OBJECTIVEThe aim of this study was to compare sensitivity and specificity between the novel threshold and amplitude criteria for motor evoked potentials (MEPs) monitoring after transcranial electrical stimulation (TES) during surgery for supratentorial lesions in the same patient cohort.METHODSOne hundred twenty-six patients were included. All procedures were performed under general anesthesia. Craniotomies did not expose motor cortex, so that direct mapping was less suitable. After TES, MEPs were recorded bilaterally from abductor pollicis brevis (APB), from orbicularis oris (OO), and/or from tibialis anterior (TA). The percentage increase in the threshold level was assessed and considered significant if it exceeded by more than 20% on the affected side the percentage increase on the unaffected side. Amplitude on the affected side was measured with a stimulus intensity of 150% of the threshold level set for each muscle.RESULTSEighteen of 126 patients showed a significant change in the threshold level as well as an amplitude reduction of more than 50% in MEPs recorded from APB, and 15 of the patients had postoperative deterioration of motor function of the arm (temporary in 8 cases and permanent in 7 [true-positive and false-negative results]). Recording from TA was performed in 66 patients; 4 developed postoperative deterioration of motor function of the leg (temporary in 3 cases and permanent in 1), and showed a significant change in the threshold level, and an amplitude reduction of more than 50% occurred in 1 patient. An amplitude reduction of more than 50% occurred in another 10 patients, without a significant change in the threshold level or postoperative deterioration. Recording from OO was performed in 61 patients; 3 developed postoperative deterioration of motor function of facial muscles (temporary in 2 cases and permanent in 1) and had a significant change in the threshold level, and 2 of the patients had an amplitude reduction of more than 50%. Another 6 patients had an amplitude reduction of more than 50% but no significant change in the threshold level or postoperative deterioration.Sensitivity of the threshold criterion was 100% when MEPs were recorded from APB, OO, or TA, and its specificity was 97%, 100%, and 100%, respectively. Sensitivity of the amplitude criterion was 100%, 67%, and 25%, with a specificity of 97%, 90%, and 84%, respectively.CONCLUSIONSThe threshold criterion was comparable to the amplitude criterion with a stimulus intensity set at 150% of the threshold level regarding sensitivity and specificity when recording MEPs from APB, and superior to it when recording from TA or OO.

OBJECTIVEAcute or progressive myelopathy may necessitate direct anterior decompression of the craniocervical junction and odontoidectomy. Different techniques with individual advantages and disadvantages can be used. In addition to the gold standard—the transoral approach—there is also increasing experience with the endoscopic transnasal technique. Other alternative methods are also being developed to reduce technical and perioperative problems. The aim of this anatomical study was to investigate the feasibility of the full-endoscopic uniportal technique with a retropharyngeal approach for decompression of the craniocervical junction, taking into consideration the specific advantages and disadvantages compared with conventional methods and the currently available data in the literature.METHODSFive fresh adult cadavers were operated on. The endoscope used has a shaft cross-section of 6.9 × 5.9 mm and a 25° viewing angle. It contains an eccentric intraendoscopic working channel with a diameter of 4.1 mm. An anterior retropharyngeal approach was used. The anatomical structures of the anterior craniocervical junction were dissected and the bulbomedullary junction was decompressed.RESULTSThe planned steps of the operation were performed in all cadavers. The retropharyngeal approach allowed the target region to be accessed easily. The anatomical structures of the anterior craniocervical junction could be identified and dissected. The bulbomedullary junction could be adequately decompressed. No resections of the anterior arch of the atlas were necessary in the odontoidectomy.CONCLUSIONSUsing the full-endoscopic uniportal technique with an anterior retropharyngeal approach, the craniocervical region can be adequately reached, dissected, and decompressed. This is a minimally invasive technique with the known advantages of an endoscopic procedure under continuous irrigation. The retropharyngeal approach allows direct, sterile access. The instruments are available for clinical use and have been established for years in other operations of the entire spine.

OBJECTIVEDiffuse intrinsic pontine glioma (DIPG) is a highly aggressive and lethal brainstem tumor in children. In the 1980s, routine biopsy at presentation was abandoned since it was claimed “unnecessary” for diagnosis. In the last decade, however, several groups have reincorporated this procedure as standard of care or in the context of clinical trials. Expert neurosurgical teams report no mortality and acceptable morbidity, and no relevant complications have been previously described. The aim of this study was to review needle tract dissemination as a potential complication in DIPG.METHODSThe authors retrospectively analyzed the incidence of dissemination through surgical tracts in DIPG patients who underwent biopsy procedures at diagnosis in 3 dedicated centers. Clinical records and images as well as radiation dosimetry from diagnosis to relapse were reviewed.RESULTSFour patients (2 boys and 2 girls, age range 6–12 years) had surgical tract dissemination: in 3 cases in the needle tract and in 1 case in the Ommaya catheter tract. The median time from biopsy to identification of dissemination was 5 months (range 4–6 months). The median overall survival was 11 months (range 7–12 months). Disseminated lesions were in the marginal radiotherapy field (n = 2), out of the field (n = 1), and in the radiotherapy field (n = 1).CONCLUSIONSAlthough surgical tract dissemination in DIPG is a rare complication (associated with 2.4% of procedures in this study), it should be mentioned to patients and family when procedures involving a surgical tract are proposed. The inclusion of the needle tract in the radiotherapy field may have only limited benefit. Future studies are warranted to explore the benefit of larger radiotherapy fields in patients with DIPG.

Adequate water availability in irrigation systems is an important factor in the success of irrigation agriculture, including Sungai Tabuk irrigation system which land is planted with rice paddy, fields rice paddy and crops. The availability of water in Kecamatan Tabuk River was calculated by dependable flow analysis using flow data from Mock method calculation. The model of rainfall-flow relationship with the monthly interval used was Mock Method, and 80% dependable flow was used to calculate the availability of the irrigation water. Based on the rainfall and evapotranspiration data (Mock method) in irrigation system of Sungai Tabuk area, the average flow per year of 5.758 m3 / sec obtained. With the highest flow occurred in March of 9.405m3 / sec and the lowest flow was in September at 1.616 m3 / sec. The 80% dependable flow was an average of 3.504 m3 / sec with the highest 80% of the highest dependable flow recorded in February of 7.37 m3 / sec and the lowest flow was in October which 80% flow was 0.24 m3 / sec. The calculation of irrigation water needed was based on KP-01. The calculation results showed that the average water demand was 2.690 m3 / sec with the beginning of planting on December I by using ordinary rice-ordinary rice planting pattern; while the average water demand for crops was 0.029 m3 / sec. From the analysis, the availability of irrigation water of Sungai Tabuk (average value of 3,504 m3 / sec) can fulfil the irrigation water requirement (average value of 2,690 + 0,029 = 2,719 m3 / second).

Reduced forest products cause also reduced of large-dimensional wood that has high quality. One alternative to solve the problem is by doing laminate engineering by combining different quality wooden layers into specific sized beams as desired. The type of wood and the position of layer give effect to the laminate beam capacity. The aim of this research was to find out the flexural capacity (MOR) of Mahang and Meranti wood laminated beams which layers were varied which then the result of the laminated beam was compared with the solid beams. There were 3 types of laminate specimens made with dimension 5x7x76 cm3 which consisted of 7 layers; BL K1 beam consisted of 2 layers of Meranti wood at the top and bottom of the beam and 5 layers of Mahang in the middle; BL K2 beam consisted of 4 layers of Meranti wood at the top and bottom of the beam, and 3 layers of Mahang in the middle; and BL K3 beam consisted of 6 layers of Meranti wood at the top and bottom of the beam and 1 layer of Mahang in the middle. The test results showed that the use of wood of higher specific gravity at the outermost layer has increased the flexural capacity (MOR) and modulus of elasticity (MOE), particularly in laminated beams (Meranti wood and Mahang wood) with the same numbers of layers. Moreover, in same number or greater layer proportion between Mahang and Meranti wood, the result showed the increased of MOR and MOE of laminated beams compared with solid beam that has low specific gravity (Mahang).
