Abstract:

Microencapsulation of curcumin in jelly fig pectin was performed by the vacuum spray drying (VSD) technique. The VSD was advanced with a low inlet temperature of 80–90 °C and low pressure of 0.01 mPa. By the in situ cross-linking with multivalent calcium ions, jelly fig pectin produced stable curcumin encapsulated microparticles. The physiochemical characteristics of microparticles were thoroughly investigated. The results revealed that 0.75 w/w% of jelly fig pectin and inlet temperature of 90 °C could be feasible for obtaining curcumin microparticles. The VSD technique showed the best encapsulation efficiency and yield and loading efficiency was up to 91.56 ± 0.80%, 70.02 ± 1.96%, and 5.45 ± 0.14%, respectively. The curcumin was readily released into simulated gastrointestinal fluid with 95.34 ± 0.78% cumulative release in 24 h. The antioxidant activity was stable after being stored for six months and stored as a solution for seven days at room temperature before analysis. Hence, the VSD technique could be applicable for the microencapsulation of bioactive compounds such as curcumin to protect and use in the food/pharmaceutical industry.

Abstract:

Enlargement of the bulboventricular foramen (BVF) in double-inlet left ventricle or the ventricular septal defect (VSD) in tricuspid atresia with transposition of the great arteries is one approach for prevention or treatment of systemic ventricular outflow obstruction. Most often, BVF/VSD restriction is bypassed preemptively or addressed directly at the time of Glenn/Fontan procedures as part of staged univentricular palliation. We describe a patient who underwent enlargement of a restrictive VSD during Fontan completion and subsequently presented with an asymptomatic pseudoaneurysm of the right ventricle at the ventriculotomy site.

Abstract:

Introduction: Ventricular Septal Defect (VSD) is a common congenital heart disease. Three therapeutic approaches exist to treat this anomaly: observation and regular follow-up, surgical closure, and Tran’s catheter intervention. We seek through this study to determine the appropriate indications for surgical and nonsurgical treatment of VSD. Methods: We conducted a retrospective multicentric study between January 1, 2000 and June 30, 2020 on 942 VSD carriers. Cases with isolated VSD were studied for age of presentation, sex, type of VSD, and VSD outcome. Results: Majority of our patients (60.5%) had a perimembranous VSD. During 20 years of follow-up, 220 underwent an intervention for their cardiac anomaly (either surgery or catheterization) and 722 received medical treatment and were under observation. Among patients who were solely monitored, 36.7% patients had a complete spontaneous closure of their VSD, 20.9% had a partial closure, and 39.9% had an unchanged VSD size. Patients with perimembranous and inlet types were significantly more likely to undergo an intervention (p=0.018). The most common reason behind intervention was severe pulmonary arterial hypertension seen in 140 cases. Furthermore, 18 cases out of 457 unclosed VSD developed complications during follow-up. Conclusion: We found that 36.7% of VSDs might totally close over time, particularly if VSD is of muscular type. This rate might also increase with a longer follow-up period.

Abstract:

Background: Ventricular septal defect (VSD) is the most commonly recognized congenital heart defect. Isolated VSDs represent about 20-30% of all congenital cardiac malformations and have a prevalence of 1- 2 % per 1,000 live births.Objective: This study is planned to review the outcome of surgical closure of VSD at Ibn Al-Nafees Teaching Hospital (Department Cardiac Surgery) Baghdad/Iraq.Patients and methods: This study includes 50 cases of VSD both isolated and VSD associated with other congenital malformations admitted and underwent surgical repair of age range between 3 to 28 years and weight range between 9 to 80 kg. Different type of VSD, were found and repaired whether isolated or with other associated congenital anomalies which dealt with at the same time.Results: The following VSD types were found: 40 peri- membranous 80%, 3 outlet 6%, 5 inlet 10% and 2 muscular 4%. Additional surgery were 3 pulmonary valvotomy 6%, 3 right ventricular outflow patch 6%, 7 closure of atrial septal defect 14%, 2 excision of subaortic ridge 4% and 2 aortic valve replacement 4%. One patient required reoperation for bleeding. Four patients had complete heart block that required temporary pacemaker. Over all operative mortality were two cases (4%), median postoperative hospital length stay was 7 days (range 5-18 days).Conclusions: Surgical closure of VSD is a safe and effective therapy in isolated VSD or VSD with other malformations and reoperation is minimal. Other cardiac malformations can be repaired at the same time with the closure of VSD with good results and very minimal complications.

Abstract:

Conventional constant speed turbo air centrifugal compressor systems (TACCSs) consist of an electric motor driven at the constant speed and an inlet guide vane (IGV) for pressure control. TACCSs with an inverter for a variable speed drive (VSD) of the electric motor are more efficient than the conventional constant speed TACCS because they have a wide operating range and can minimize the power consumption. Therefore, this paper proposes a quadratic V/f control and VSD to reduce electrical and mechanical energy losses. To verify the energy saving effect of the TACCS with the proposed controls, this paper analyzes the performances of an electric motor drive system (EMDS) using the proposed quadratic V/f control considering load conditions of the turbo air centrifugal compressor (TACC) to reduce electrical energy losses. Furthermore, the performances of the conventional constant speed drive (CSD) using the IGV control and the proposed VSD were compared and analyzed in the test bench that represented an actual factory environment. As a result, the proposed quadratic V/f control and VSD experimentally verified energy savings of 4.44% and 23.37% compared to conventional controls. In addition, the economic feasibility of the proposed VSD was verified in the TACCS by analyzing the recovery period of the initial investment due to the addition of the inverter.

Abstract:

Background: Many issues might arise with surgical closure, such as postoperative pain, sternotomy scar, and postoperative arrhythmias as well as heart block. The purpose of this study was to identify the risk factors for complete heart block (CHB) among children following surgical ventricular septal defect (VSD) closure. Methods: This retrospective work was performed on 126 pediatric individuals, with a history of VSD closure surgically. There were two groups of participants: Group 1 (Post-surgical CHB group): (n=42) had CHB. and Group 2 (Post-surgical non CHB group): (n=84) without CHB. Results: Temporary Pacemaker was needed in 11 cases (26.19%), temporary then endocardial pacemaker occurred in 21 cases (50%), epicardial pacemaker occurred in 3 cases (7.14%), and endocardial pacemaker in 7 cases (16.67%). No complications occurred in 38 cases (90.48%), sepsis after one week occurred in 1 case (2.38%). Body weight at closure, type of VSD, mean pulmonary arterial pressure (mPAP) before surgery and procedure time were independent significant predictors for occurrence of CHB (P<0.05). Conclusions: Low body weight at closure, large peri-membranous and inlet VSD, high mPAP before surgery were independent significant risk factors or predictors for occurrence of CHB after surgical closure of VSD. Pacemaker therapy is the only beneficial therapy of post-operative CHB.

Abstract:

Ventricular septal defect (VSD) is the mostcommon congenital heart disease (CHD)in children.1'2 It occurs in 1.5 to 3.5 of1,000 live births and constitutes 20% ofcongenital cardiac defects.1 The VSD may be small,medium or large and is classified based on its locationin the interventricular septum. There are four types ofVSD, i.e., perimembranous (80% ofVSDs), musculartype (5% to 20%) inlet or AV canal type (8%), andfinally, subpulmonary (5% to 7%).1-4 When multiplemuscular defects are seen, it is often referred to as"Swiss-cheese" type of VSD. 1•2The management strategies, which consist ofmedical, surgical and intervention techniques, depend toa large degree on the size of the VSD.1-4 Approximately40% of VSDs spontaneously and completely closed,with closure rates approaching 80-90% by age 2 years.2Indication ofVSD closure are symptoms of heart failure,left heart chambers overload and history of endocarditis.The surgical approach is considered gold standard butit is associated with morbidity and mortality, high cost,patient discomfort, sternostomy and skin scar.3 Since1988, percutaneous techniques have been conductedin order to reduce those drawbacks of surgery. Morerecently, percutaneous techniques and devices havebeen developed specifically for closure of muscularVSD (m VSD) and perimembranous VSD (pm VSD)using either the Rashkind double umbrella, the BardClamshell, the Button device, theAmplatzer septal, duct118 • Paediatr lrulones, Vol. 50, No. 2, March 2010or muscular VSD occluder, or the Gianturco coils.3AGianturco coils have been widely used to closeunwanted vascular communications and small- tomoderate- sized patent ductus arteriosus, withexcellent closure rates. In 1999, Latiff et al successfullyused this coil to close multiple muscular VSDs in a10-month old boy. Thus, percutaneuos closure ofVSDs using Gianturco coils is a feasible, reasonablealternative to surgery.5'6 We report a case of fouryear-old girl with muscular VSD who underwentcardiac catheterization and transcatheter closure withGianturo coil in Dr. Soetomo Hospital, Surabaya.

Abstract:

Ventricular septal defect (VSD) is a congenital heart disease (CHD) which characterized bya hole in the wall that separate between the right and left ventricle. There are several typesof VSD based on its location, which are perimembranous/conoventricular, subpulmonary/conotruncal, supracristal/doubly commited, muscular and atrioventricular canal/inlet. AVSD is one of the most common CHD which occurs in approximately 2-6 of every 1,000live births and accounts for more than 20% of all CHDs. However, the population of VSDpatients with grown up congenital heart disease (GUCH) is still uncertain. We are presentinga rare case of a 19 year old patient with congestive heart failure NYHA functional class IVdue to uncorrected left-to-right shunt supracristal VSD with body mass index of 35.5 kg/m2. He presented in the emergency room with acute decompensated heart failure profileB. Echocardiography revealed decreased left ventricle (LV) systolic function, normal rightventricle (RV) systolic function, decreased LV diastolic function, and dilated left atriumand LV. We plan to perform right heart catheterisation and pulmonary artery oxygenresponsiveness test followed by VSD closure in this patient. Another explanation will bediscussed in this paper.

Abstract:

Background: Ventricular septal defect (VSD) and atrial septal defect (ASD) are congenital heart diseases. The techniques of transthoracic closure (TC) and percutaneous closure (PC) for the treatment of VSD and ASD have continuously improved and matured. This study aimed to retrospectively analyze the therapeutic effects of TC and PC on VSD and ASD patients. Methods: We retrospectively reviewed 928 patients (552 VSD and 376 ASD) who had undergone TC or PC guided by transesophageal ultrasound at the Department of Cardiac Macrovascular Surgery of the First Affiliated Hospital of Nanchang University between August 2010 and August 2020. We collected and evaluated the clinical data of the patients, including age, gender, weight, inlet and outlet diameters of defect, and the operation results of TC and PC. Descriptive statistics were used to analyze means and standard deviations (SD), and the Chi-square test was used to evaluate the difference between groups. Results: Among the 928 patients who were treated with the closure operation, there were no casualties, with 907 patients (97.7%) showing successful closure. Among the 552 VSD patients who were treated with TC, 540 showed successful close, while 12 cases required extracorporeal circulation after the failure of TC. Among the 376 patients with ASD, 256 patients were treated with TC, of which 251 were successful, and five were failures, including three shedding cases. In addition, among the 120 patients who were treated with PC, 116 were successful, and four were failures, including two shedding cases. Postoperative follow up for patients with successful closure operations demonstrated that the complications of aortic and tricuspid regurgitation, hydro-pericardium, III° atrioventricular block, shedding of closure umbrella, hemolysis, and thrombosis had not occurred. Conclusion: Closure operation of VSD and ASD by esophageal ultrasound has the advantages of lower trauma and blood loss, shorter hospital stay, simple operation, fewer postoperative complications, and significant therapeutic efficacy.

Abstract:

The Gerbode defect is a defect between the left ventricle and the right atrium and can be congenital or acquired. It is known that structural heart diseases may occur secondary to mechanical damage/trauma. The Gerbode defect, sinus Valsalva injuries, and tricuspid valve damage are the most frequently reported acquired heart diseases due to vehicle accidents or mechanical traumas. Herein, we shared the first case of ventricular septal defect (VSD), aortic dissection, Gerbode defect, and severe tricuspid valve damage secondary to trauma caused by a truck tire explosion and its transcatheter/surgical management. A 13-year-old male patient, who was standing next to a truck when he suddenly fell to the ground after feeling severe chest pain due to the pressure effect of a high-pressure truck tire explosion, was referred to our hospital. The patient had a history of thoracic endovascular aortic repair due to VSD and aortic dissection in the descending thoracic aorta. The echocardiographic evaluation revealed right atrium enlargement, perimembranous VSD extending to the inlet region, 8-mm direct Gerbode defect causing a shunt between the left ventricle and the right atrium, and defects of up to 5 mm in size on the tricuspid valve septal leaflet causing severe tricuspid insufficiency. The patient underwent surgery for VSD closure. Two separate patches were used for VSD closure (one for the Gerbode-type defect and the second one for the perimembranous-type defect). There were no defects on the tricuspid valve; therefore, two separate patches were used for closure. Cardiac traumas may be examined under two groups: penetrating cardiac traumas and blunt cardiac traumas. The most common abnormality following a blunt cardiac trauma is asymptomatic myocardial contusion.

A 13-year-old male patient, who was standing next to a truck when he suddenly fell to the ground after feeling severe chest pain due to the pressure effect of a high-pressure truck tire explosion, was referred to our hospital. The patient had a history of thoracic endovascular aortic repair due to VSD and aortic dissection in the descending thoracic aorta. The echocardiographic evaluation revealed right atrium enlargement, perimembranous VSD extending to the inlet region, 8-mm direct Gerbode defect causing a shunt between the left ventricle and the right atrium, and defects of up to 5 mm in size on the tricuspid valve septal leaflet causing severe tricuspid insufficiency. The patient underwent surgery for VSD closure. Two separate patches were used for VSD closure (one for the Gerbode-type defect and the second one for the perimembranous-type defect). There were no defects on the tricuspid valve; therefore, two separate patches were used for closure. Cardiac traumas may be examined under two groups: penetrating cardiac traumas and blunt cardiac traumas. The most common abnormality following a blunt cardiac trauma is asymptomatic myocardial contusion.

Abstract:

Background: Diagnosing congenital cardiac malpositions can be complex, especially when multiple anomalies coexist. We report an unusual case of supero-inferior (upstairs-downstairs) ventricular arrangement with a criss-cross inlet, in a neonate with D-looped transposition of the great arteries (D-TGA), double outlet right ventricle (DORV), and hypoplastic aortic arch with coarctation of the isthmus. Case Presentation: The patient, diagnosed antenatally with DORV, D-TGA, and hypoplastic arch, was born in stable condition and started on prostaglandin E1 infusion. Postnatal echocardiography and CT angiography revealed a criss-cross heart (CCH) with supero-inferior ventricles. At 2-3 weeks, the patient underwent aortic arch repair and pulmonary artery (PA) banding. Subsequently, balloon atrial septostomy caused an intimal tear in the inferior vena cava (IVC), requiring IVC stenting. Over several months, PA band revision and selective left PA banding were necessary due to recurrent band loosening and stenosis. A Jatene arterial switch and ventricular septal defect (VSD) repair are planned after the infant reaches appropriate weight. Investigations: Imaging confirmed situs solitus with atrioventricular concordance and ventriculoarterial discordance. A large VSD without inlet valve straddling, double outlet right ventricle, and plethoric lung fields were noted. The criss-cross inlet was characterized by a misaligned right atrioventricular connection, with the right ventricle positioned superiorly and anteriorly to the left ventricle (upstairs-downstairs arrangement). Management and Outcome: Despite three sternotomies, including PA banding and multiple revisions, the child remains in high-dependency care, with plans for future surgery. Multidisciplinary team management was essential in navigating this challenging case. Conclusion: This case highlights the intricate nature of criss-cross heart with supero-inferior ventricular arrangement. Diagnosing these rare congenital anomalies requires a combination of imaging modalities, and management involves tailored surgical interventions to address the associated malformations. Early recognition and multidisciplinary collaboration are key to improving outcomes in such complex cases.

Abstract:

Mesocardia is a condition in which the heart is longitudinally oriented along its long axis in the midline. Cardiac position refers to the anatomical position of the left ventricular apex in the thorax. The heart has three positions: dextrocardia or right-sided heart, levocardia or left-sided heart, mesocardia or midline heart. Mesocardia is extremely rare. It represents only 0.2% of cardiac anomalies. Mesocardia is usually associated with cardiac structural abnormalities, heterotaxy syndrome, chromosomal disorders and genetic syndromes. Occasionally, it is an isolated finding. We are presenting an interesting case report of severely symptomatic neonate afflicted with mesocardia, situs solitus, moderate sized atrial septal defect (ASD) and large ventricular septal defect (VSD).

Abstract:

Nowadays, a lot of air conditioners use vapor compression refrigeration systems. Behind its function in supporting human needs, refrigeration systems have an impact on increasing electricity consumption. Efforts to save energy in cooling equipment are carried out by increasing its efficiency. One of them is by adding a control system to the fan motor in the evaporator and condenser sections and considering aspects of the cooling load of the refrigeration system itself. This study was conducted to find out more about the performance of the vapor compression refrigeration system with varying evaporator and condenser fan speeds. The fan speed control system uses a VSD (variable speed drive) combined with a servo motor and Arduino Uno R3. Three 5W incandescent light bulbs are placed in the evaporator air inlet, which is used as a cooling load. The final result obtained is that the most optimal control system for the vapor compression refrigeration system is the VSD control system where the electrical energy consumption is lower (which is 0.6 kW) compared to the on-off control system (which is 0.8 kW). Variations in cooling load have a significant effect on air temperature in vapor compression refrigeration systems.

Abstract:

In double inlet left ventricle (DILV), the ventricle most frequently has left ventricle (LV) morphology, although right ventricle (RV), mixed, indeterminate, or undifferentiated morphologies have been reported. The main ventricle is largely a morphological LV with an outlet chamber connected to it which has a RV morphology. Ventricular septal defect (VSD) or bulboventricular foramen size and anatomy may be variable. The AV valves may be normal, or one of them may be hypoplastic, stenotic, or even atretic. The great arteries are most frequently transposed and the aorta arises from the hypoplastic RV, and the pulmonary artery comes off the main LV chamber. L-transposition of great arteries (L-TGA) happens more often than d-transposition of great arteries (D-TGA). The great vessels are normally related in 30% of cases. Double-outlet right ventricle (DORV) may be seen, in which both great vessels arise from the rudimentary RV. Pulmonary stenosis (PS) is present in two thirds of patients and such stenosis is seen irrespective of the great artery relationship. Rarely subaortic obstruction maybe present in patients with transposition of the great arteries. Here, we are presenting a case of complex cyanotic congenital cardiac defect of DILV with VSD complicated by L-TGA and severe tricuspid regurgitation (TR) in a 3-year-old male toddler.

Abstract:

In this review management of the most common cyanotic congenital heart defects (CHDs) was discussed; the management of acyanotic CHD was reviewed in Part I of this series. While the need for intervention in acyanotic CHD is by and large determined by the severity of the lesion, most cyanotic CHDs require intervention, mostly by surgery. Different types of tetralogy of Fallot require different types of total surgical corrective procedures, and some may require initial palliation, mainly by modified Blalock–Taussig shunts. Babies with transposition of the great arteries with an intact ventricular septum as well as those with ventricular septal defects (VSD) need an arterial switch (Jatene) procedure while those with both VSD and pulmonary stenosis should be addressed by Rastelli procedure. These procedures may need to be preceded by prostaglandin infusion and/or balloon atrial septostomy in some babies. Infants with tricuspid atresia require initial palliation either with a modified Blalock–Taussig shunt or banding of the pulmonary artery and subsequent staged Fontan (bidirectional Glenn and fenestrated Fontan with extra-cardiac conduit). Neonates with total anomalous pulmonary venous connection are managed by anastomosis of the common pulmonary vein with the left atrium either electively in non-obstructed types or as an emergency procedure in the obstructed types. Babies with truncus arteriosus are treated by surgical closure of VSD along with right ventricle to pulmonary artery conduit. The other defects, namely, hypoplastic left heart syndrome, pulmonary atresia with intact ventricular septum, double-outlet right ventricle, double-inlet left ventricle and univentricular hearts largely require multistage surgical correction. The currently existing medical, trans-catheter and surgical techniques to manage cyanotic CHD are safe and effective and can be performed at a relatively low risk.

Abstract:

This study investigated the spread of MRSA (methicillin-resistant <em>Staphylococcus aureus</em>) on two Belgian pig farms. Pigs of different ages (from farrowing to slaughter age and sows) as well as the barn environment were screened extensively on two occasions three months apart. A subset of MRSA isolates was tested for antimicrobial susceptibility to 16 antibiotics and was further characterized by pulsed-field gel electrophoresis. Ninety-five percent and 77% of the tested pigs on farm A and farm B, respectively, were colonized with MRSA. MRSA positive animals were detected in all age categories sampled on each sampling day. Piglets were already colonized in the farrowing unit with the same or other MRSA strains than their mother. The prevalence of MRSA colonized pigs increased significantly after weaning and decreased during the fattening period. Pigs carried MRSA mainly in the nares, followed by the perineum and skin and to a lesser degree the rectum. A pig could be contaminated or colonized with different MRSA strains at the same time. The barn environment was also found to be contaminated with different MRSA strains, including the air inlet and outlet. All isolates tested on both farms were resistant to both tetracycline and trimethoprim, while they were susceptible to rifampicin, mupirocin and linezolid. There was a significant difference in resistance prevalence between the two farms for the antibiotics gentamicin, kanamycin, tobramycin, tylosin, lincomycin and quinupristin/dalfopristin. Furthermore, several antibiotic resistance profiles were observed within one farm. This study clearly indicates that several MRSA strains circulate on one farm, from the nursery unit to the fattening unit. This is important to consider when attempts are made to remediate these farms.

Abstract:

Objectives: To review the outcomes of direct innominate artery cannulation for continuous cerebral perfusion used for repair of interrupted aortic arch (IAA) in a consecutive cohort of neonates regardless of weight. Methods: Between September 1999 and April 2016, forty-four children with IAA (18 type A and 26 type B) underwent repair using continuous, hypothermic (18°C) low-flow cerebral perfusion via direct innominate artery cannulation. Associated cardiac lesions were truncus arteriosus (TA; 5), ventricular septal defect (VSD; 30), transposition of the great arteries (TGA; 1), unbalanced atrioventricular septal defect (1), double-inlet left ventricle (1), double-outlet right ventricle (3), and aortopulmonary window (APW; 5). Truncus arteriosus, single VSD, TGA, and APW were corrected while the other patients were palliated. Results: Age at the time of surgery was 7 days (4-120 days) and weight 3.1 kg (2.1-5.8 kg). Selective cerebral perfusion was maintained in all patients. During the selective cerebral perfusion, perfusion flow rate was maintained at 30 mL/kg/min. Aortic cross-clamp time, low-flow, and total cardiopulmonary bypass time were 63 (40-116), 28 (17-41), and 108 (80-217) minutes, respectively. There were no deaths nor clinical evidence of neurological injury. Postoperative ventilation time, length of intensive care unit, and hospital stay were 3 (2-14), 5 (3-21), and 13 (6-27) days, respectively. Follow-up, complete at 84 months (24-221), revealed no late clinically evident neurologic sequelae nor innominate artery complications. Conclusions: Direct innominate arterial cannulation with continuous selective cerebral perfusion can be safely applied for repair of IAA even in low birth weight neonates. It is technically simple and associated with excellent clinical outcomes.

Abstract:

Background:Congenital heart disease (CHD) is the commonest of all congenital lesions and is the most common type of heart disease among children. Congenital heart disease, in a definition proposed by Mitchell et al is a gross structural abnormality of the heart or intrathoracic great vessels that is actually or potentially of functional significance. It is the most common cause of major congenital anomalies, representing a major global health problem. Twenty-eight percent of all major congenital anomalies consist of cardiac anamolies. In India, 10% of the present infant mortality may be accounted for by Congenital Heart Disease as reported by Saxena et al. Aim: To study the Spectrum of Neonatal Congenital Cardiac Disorders Material and methods:It was an observational prospective study carried out in the Neonatology Section, Department of Pediatrics, GB Panth Childrens hospital Srinagar from November 2017 to August 2019. Results:During the two year study, 471 neonates were diagnosed with congenital heart disease in which 335 (71.1%) were acyanotic and 136 (28.9%) were cyanotic. Males and females comprised of 253 and 218 respectively with a male to female ratio of 1.2:1. The most common cyanotic CHD was d-transposition of great arteries (d-TGA) 39 (8.3%), followed by tetralogy of Fallot (TOF) 23 (4.9%) and single ventricle (double inlet left ventricle [DILV] with pulmonary arterial hypertension/pulmonary stenosis [PAH/PS]) 17 (3.6%). In our study the most common acyanotic CHD was ventricular septal defect (VSD) 103 (32.5%) followed by atrial septal defect (ASD) 98 (20.8%) and PDA 47 (10.0%). Conclusion:Congenital heart disease (CHD) is a common congenital disorder of the neonatal population. Early diagnosis and timely management are key factors for optimal outcome of this problem.

Abstract:

Pregnancy is not always well tolerated in women with congenital heart disease (CHD) such as atrio-ventricular septal defect (AVSD), predominantly due to heart failure deterioration and increasing pulmonary hypertension (PH). Managements of those patients are challenging, especially during third trimester and after delivery care. Decision about time of termination, mode of delivery and anesthetic management are also debatable. In this article we report two similarcases of pregnant women with AVSD and severe PH. The frst patient was 27 years old, 28-29 weeks pregnant came with shortness of breath. She had history of miscarriage once. Based on her transthoracal echocardiography, she was diagnosed with AVSD partial type (primum ASD) with severe PH and then treated with intravenous furosemide, oral beraprost and oral sildenafl. The second patient was 27 years old 30-31 weeks pregnant with shortness of breathand appeared cyanotic. She delivered her frst child spontaneously without any symptoms. Based on her transthoracal echocardiography she was diagnosed with AVSD transitional type (large primum ASD with small inlet VSD) and Eisenmenger syndrome. She was treated with intravenous furosemide and oral beraprost. Those two patients underwent planned C-section under general anesthesia, both babies were survived but the patient did not survived severaldays after the procedure due to PH crisis. Until now, management PH associated with CHD in pregnant women is complex. Fluid management and pulmonary artery hypertension (PAH)- targeted therapies are important. Mode of delivery on this cases is also remain debated. Some studies stated planned C-section might be a better choice and combination epidural and lowdose spinal anesthesia might be better than general anesthesia. At the end, when a woman with CHD and PH chooses to continue pregnancy, multidisciplinary team approach is crucial to achieve good outcomes.

Abstract. Convective cooling is a critical management strategy for maintaining an environment that promotes production efficiency, thermal comfort, and animal well-being in commercial broiler houses. Variations in house size, design, and equipment configuration contribute greatly to the air velocity distribution within the facility. This study assessed total airflow, air velocity distribution, and quantified the floor area in three facilities experiencing insufficient air velocity for maintenance of production efficiency, thermal comfort, and animal well-being. Test facility 1 was an 18.3 × 170.7 m solid side-wall broiler house, test facility 2 was a 15.24 × 144.8 m solid side-wall broiler house, and test facility 3 was a 12.19 × 121.9 m curtain side-wall broiler house. Total airflow of each facility, measured with a Fan Assessment and Numeration System, was 512,730, 389,495, and 329,270 m3 h-1 for test facilities 1, 2, and 3, respectively. Air velocity distribution patterns were characterized in each house with a Scalable Environment Assessment System (SEAS) and spatial statistics. The air velocity distributions within the test facilities were variable, with notable maxima immediately downstream of the tunnel inlets, which serve as a well-defined vena contracta, and local minima near the leading end of the evaporative pads and the exhaust fans. Equipment within the facilities had an impact on the air velocity distribution by creating reduced cross-sectional areas that resulted in localized increases in air velocity. The percentage of total bird-level floor area in each facility experiencing air velocities below 1.5 m s-1 was 14.3%, 20.7%, and 10.0% for test facilities 1, 2, and 3, respectively. The effective design velocity (Ved) was calculated from total airflow using the measured building cross-sectional area. The Ved measured 2.97, 2.45, and 2.34 m s-1 for test facilities 1, 2, and 3, respectively. Mean cross-sectional air velocity (Vcs) was calculated from SEAS data and normalized using each facility’s Ved to account for differences in building size for comparison. Test facility 1, the largest of the three houses, generated substantially higher Vcs/Ved than test facilities 2 and 3. Test facilities 2 and 3 maintained a larger proportion of Vcs above Ved than test facility 1. Test facility 1 showed 26.5% of the total house length below Ved, while test facilities 2 and 3 had only 20.8% and 17.5%, respectively, of the total house length below Ved. The lower-velocity regions were due to the length of the evaporative cooling pad inlet and the use of tunnel doors, and the exhaust fan placement on the side-walls in test facility 1 created an additional pronounced low-velocity area. Placement of tunnel ventilation fans on the end-wall of the facility, rather than the side-wall, eliminated the low-velocity region at the exhaust end of the facility. Modifications to current practices for broiler production facility construction and evaporative cooling pad inlet installation would be required to minimize the low-velocity region at the inlet end of these facilities. Consideration of house width and physical arrangement of the air inlets, tunnel fans, and internal equipment are critical for improving the uniformity of air velocity in commercial broiler houses.

Abstract:

I de avslutande styckena av ”L’Étourdit”, ursprungligen en föreläsning framförd vid femtioårsjubileet av l’Hôpital Henri-Rousselle i Paris 1972 och sedan publicerad året därpå i Scilicet, plockar Lacan på nytt upp Demokritos atomism. Genom att återvända till denna lära, som tidigare diskuterats vid en av föreläsningarna i det elfte seminariet, öppnar Lacan inte bara frågan om negativiteten, om varat och intet och hur vi går från intet och varat via blivandet till något, det vill säga frågan om ontologin och dess genesis, utan minst lika mycket ställer han frågan om det omedvetna och repetitionen. Upprepandet av Demokritos atomism, problemet som rör den och mēden, pekar därmed ut ett fundamentalt problem för psykoanalysen. Och i den mån ”L’Étourdit” i sig utgör en vändning, det vill säga att texten har funktionen av såväl en sammanfattning av Lacans arbete fram till 1972 som ett avstamp mot framtiden, är det mot de frågor som hemsökt Lacan i relation till formulerandet av de fyra diskurserna som tagit sin början tre år tidigare som den riktar sig. Det faktum att frågan om subjektets tal, och att det som sägs förblir dolt bakom det som hörs och förstås i det sagda, och den relaterade frågan om hur diskursen kan nå bortom sig själv, eller att, som Lacan uttrycker det, ”Demokritos nämligen gör oss till en gåva från [de] ατομος, från det radikalt reella” (2001 [1973]): 494), får sin upplösning just i Demokritos atomism bör peka ut den centrala, och samtidigt tvetydiga, position denna teori får i psykoanalysens mest centrala formuleringar av det omedvetna och begäret.

Abstract:

Vortex drop shaft (VDS) spillways are eco-friendly hydraulic structures used for safely releasing flood. However, due to the complexity of the three-dimensional rotational flow and the lack of suitable measuring devices, current experimental work cannot interpret the flow behavior reliably inside the VDS spillway, consequently experimental and CFD study on a VDS spillway with an elliptical tangential inlet was conducted to further discern the interior three-dimensional flow behavior. Hydraulic characteristics such as wall pressure, swirl angle, annular hydraulic height and Froude number of the tapering section are experimentally obtained and acceptably agreed with the numerical prediction. Results indicated that the relative dimensionless maximum height of the standing wave falls off nearly linearly with the increasing Froude number. Nonlinear regression was established to give an estimation of the minimum air-core rate. The normalized height of the hydraulic jump depends on the flow phenomena of pressure slope. Simulated results sufficiently reveal the three-dimensional velocity field (resultant velocity, axial velocity, tangential velocity and radial velocity) with obvious regional and cross-sectional variations inside the vortex drop shaft. It is found that cross-sectional tangential velocity varies, resembling the near-cavity forced vortex and near-wall free vortex behavior. Analytic calculations for the cross-sectional pressure were developed and correlated well with simulated results.

Abstract:

We report on comparative in vitro tests of two ventricular assist devices (VAD) one with a rigid input cannula and the other with a collapsible (compliant) inlet cannula. We show how this compliant cannula yields significant improvements in the hydrodynamic performance of the system.

Det er umuligt at komme uden om: Når det kommer til dansk historie på film og TV, står intet over og intet ved siden af Lise Nørgaards købstadsepos om provinsdanmark i årerne 1929 – 1947. Seriens påvirkning af vores historieopfattelse er så stærk, at det er lige før, Matador er Danmarks historie i 1930’erne.

Abstract:

We present a case of acute Impella thrombosis during Ecpella support in a 48-year-old man listed for a heart transplant. After two weeks of Ecpella support, echocardiography revealed a 2.6 x 1.1 cm mobile thrombus attached to the Impella inlet (Video). The Impella and attached thrombus were pulled across the aortic valve into the descending aorta and removed without systemic thromboembolism. Due to the ongoing need for left ventricular venting, a new Impella CP was placed.
