Abstract:
Abstract Preterm birth is associated with higher blood pressure, which could be because preterm birth alters early aortic elastin and collagen development to cause increased arterial stiffness. We measured central and conduit artery size and multiple indices of arterial stiffness to define the extent and severity of macrovascular changes in individuals born preterm. A total of 102 young adults born preterm and 102 controls who were born after an uncomplicated pregnancy underwent cardiovascular magnetic resonance on a Siemens 1.5 T scanner to measure the aortic cross-sectional area in multiple locations. Ultrasound imaging with a Philips CX50 and linear array probe was used to measure carotid and brachial artery diameters. Carotid-femoral pulse wave velocity and the augmentation index were measured by SphygmoCor, brachial-femoral pulse wave velocity by Vicorder and aortic pulse wave velocity by cardiovascular magnetic resonance. The cardio-ankle vascular index (CAVI) was used as a measurement of global stiffness, and ultrasound was used to assess peripheral vessel distensibility. Adults born preterm had 20% smaller thoracic and abdominal aortic lumens (2.19±0.44 vs. 2.69±0.60 cm2, P<0.001; 1.25±0.36 vs. 1.94±0.45 cm2, P<0.001, respectively) but similar carotid and brachial diameters to adults born at term. Pulse wave velocity was increased (5.82±0.80 vs. 5.47±0.59 m s−1, P<0.01, 9.06±1.25 vs. 8.33±1.28 m s−1, P=0.01, 5.23±1.19 vs. 4.75±0.91 m s−1, P<0.01) and carotid distensibility was decreased (4.75±1.31 vs. 5.60±1.48 mm Hg−1103, P<0.001) in this group compared with the group born at term. However, the global and peripheral arterial stiffness measured by CAVI and brachial ultrasound did not differ (5.95±0.72 vs. 5.98±0.60, P=0.80 and 1.07±0.48 vs. 1.19±0.54 mm Hg−1103, P=0.12, respectively). Adults who are born preterm have significant differences in their aortic structure from adults born at term, but they have relatively small differences in central arterial stiffness that may be partially explained by blood pressure variations.

Abstract:
Background Low birth weight (LBW) in neonates is a problem leading to high morbidity and mortality. Barker hypothesized that fetal cardiac remodeling during hypoxic conditions or maternal under􀁏nutrition is a risk factor for coronary heart disease in theyoung. Early vascular changes may influence cardiac function and newborns' cerebral blood flow.Objective The aim of this study was to detennine the effects of being small for gestational age (SGA) on newborns' cardiac function, left ventricular (LV) mass and superior vena cava (SYC) return.Methods This cross􀁏sectional study was conducted in Cipto Mangunkusumo Hospital from February to June 2008. LBW and nonnal newborns who fulfilled the inclusion criteria were recruited as subjects. Maternal history, infant physical examination, and echocardiography were obtained Mthin 48 hours oflife to exclude those with congenital heart disease, and assess cardiac function and SYC flow.Results Subjects were 21 preterm appropriate for gestational age (AGA), 19 SGA and 19 normal newborns. SGA newborns showed lower LV mass, stroke volume and cardiac output than normal newborns. However, these SGA parameters were not different from preterm AGA babies. In additio n, LV mass index was sig nificantly different but no difference ofSVC return between the three groups.Conclusion SGA newborns' LV function was lower than that of nonnal newborns, as low as pretenn AGA newborns. N onnal SVC return was observed in the three groups. This finding may be due to a brain􀁏sparing effect to maintain sufficient cerebral blood flowin the fetus.

Abstract:
Persistent left superior vena cava (PLSVC) is a common cardiac anomaly associated with congenital heart diseases. A diagnosis of PLSVC usually warrants a detailed fetal echocardiography. Lesser known associations are the extra cardiac anomalies notably the upper airway and the gastrointestinal tract anomalies. We highlight here the importance of detailed fetal assessment for extra cardiac anomalies in addition to fetal echocardiography in fetuses diagnosed with PLSVC. We hereby present a preterm infant who presented with a triad of PLSVC, laryngeal atresia, and esophageal atresia.

Abstract:
Invasive fungal infections (IFIs) are an important cause of neonatal mortality and morbidity. A total of 5% of IFIs are complicated by fungal endocarditis. Mortality can be as high as 50%. We present a preterm, very low birth weight infant with infective endocarditis. Echocardiography showed a large pedunculated vegetation attached to the inferior vena cava and right atrium junction. Baby had Candida tropicalis in his blood cultures and was managed conservatively with antifungals. Surgery although planned was not possible considering baby being preterm with very low birth weight.

Abstract:
Education systems in schools today are generally still oriented to the material media books and verbal material delivery by the teacher. This problem raises the lack of understanding and lack of interest of students in understanding material, especially in Biology chapter Genetics. The learning media provided by the teacher are felt to be lacking to support the achievement of maximum student learning achievement. Therefore an interesting learning media is needed that aims to foster students 'interest in learning and increase students' understanding of genetic material. Alternative learning media that can be used is with educational games. In the process of developing this educational game using the waterfall method. The selection of the waterfall method is because the process of making each stage is systematic, meaning that each stage is interrelated so that it can facilitate the making of the system. The results of this study were in the form of an educational game "The Adventure of Cali-Cali" which was tested on students to find out the improvement in learning achievement. From the data obtained at the pretest results show that students still do not understand the genetic material provided by the teacher. This is evidenced by as many as 90.3% of students who have not met the Minimum Completion Criteria (KKM). Then the treatment game was given when the posttest showed that as much as 6.50% of students did not meet the KKM. The comparison of the results of the pretest and posttest showed an increase in student learning achievement which increased to 83.8%.

Abstract:
Background: Assessment of systemic blood flow helps in choosing the appropriate drug for managing critically ill neonates with poor perfusion. Superior vena cava (SVC) flow has the potential to become a bedside gold standard method for this purpose. Aims and Objectives: To find out normal superior vena cava (SVC) flow and its correlation with left ventricular output (LVOT) in late preterm and term neonates. Materials and Methods: A cross sectional observational study was carried out at a tertiary care teaching hospital where SVC flow and left ventricular output were measured in hundred intramural healthy neonates (50 late pre-term, weighing 1500g or more and 50 term, weighing 2500g or more). SVC flow was correlated with LV output in both groups. Pearson correlation coefficient was calculated to correlate between two variables. p < 0.05 was considered significant. Results: Median SVC flow in late pre-term group was 57.83ml/kg/min, and in term neonates was 56ml/kg/min. In late pre-term babies correlation of SVC flow with LV output was better in comparison to term group (r-0.56, p<0.0001, and r-0.40, p=0.0024respectively). Conclusions: SVC flow better represents systemic blood flow in late preterm neonates in comparison to term neonates.

Abstract:
L’utilizzo dei risonatori interrati per metabarriere sismiche rappresenta una possibilità sempre più concreta verso la protezione di edifici isolati ed aree urbane o industriali. Questo lavoro di tesi, si occupa delle possibili scelte progettuali, relative alle componenti dei sopraccitati risonatori. Il modello di partenza del risonatore a cui si fa riferimento, è costituito da una massa interna in acciaio la quale è collegata ad un guscio esterno in calcestruzzo mediante due cuscinetti in gomma. Le caratteristiche del risonatore permettono di ridirigere le onde di superfice, comprese nell’intervallo 1-10 Hz, convertendole in onde di massa. In particolare si può osservare come, in base alla frequenza di risonanza propria del risonatore, questo sia in grado di manipolare le onde in ingresso a quella stessa frequenza. Quindi, si è andati a lavorare sugli elementi elastici, che inizialmente sono costituiti dai cuscinetti in gomma, cercando di lasciare invariate le caratteristiche del risonatore di partenza. In prima battuta si è provato ad ipotizzare l’utilizzo di diverse tipologie di gomma per i cuscinetti. Successivamente, si è ipotizzato di sostituire i cuscinetti in gomma con dei connettori cilindrici e molle elicoidali in acciaio. Infine è stata proposta una soluzione innovativa, sfruttando dei cavi pretesi in acciaio come sostituti dei cuscinetti in gomma. Studiando prima il modello analitico del cavo preteso e poi mediante una analisi numerica è stato possibile osservare come questa soluzione risulti funzionale sia dal punto di vista tensionale che da quello strutturale del risonatore, oltre a garantire frequenze proprie di vibrazione entro i limiti richiesti e di conseguenza garantire il corretto funzionamento del risonatore.

Abstract:
"Police officers are some of the first professionals that might have direct interaction with individuals with mental illnesses. Statistics show that from 2017 to 2020 about 3986 individuals in the United States were fatally shot by police officers (Statista, 2021). These reports indicate that at least 25% and as many as 50% of all fatal shootings involved individuals with untreated severe mental illness. The purpose of this pilot study was to test the effectiveness of a five-day psycho-educational mental health awareness training in enhancing law enforcement officers’ knowledge about mental illness, and their perceptions towards mentally ill individuals using a pretest-posttest design. The Community Attitudes Towards the Mentally Ill (CAMI) scale was used to measure participants’four mental health attitudinal domains - authoritarianism, benevolence, social restrictiveness, and community mental health ideology. The results indicate that at the completion of the training there was an increase in participants’ confidence about their knowledge of the mentally ill individuals and mental illness conditions. However, the results also indicate a slight decrease in participants' mental illness social restrictiveness sentiment after the completion of the training. Additionally, the results also show a correlation between demographic variables and some of the domains. Implications for practice are discussed."
