Authors: Pop Marian , Pop Raluca Monica
Published: February 2023

Introduction: Cardiovascular diseases are the leading cause of morbidity and mortality worldwide, and there is a need for the development of adjacent markers to assess cardiovascular risk. In this study, we examined the relationship between the areas of abdominal fat compartments, as measured by computed tomography (CT)-based planar measurements, and laboratory-validated cardiovascular risk markers.

Methods: Fat distribution was measured on CT scans in 252 patients (M: F = 1.13) who underwent routine abdominal CT, using in-house and commercially available software. The included laboratory parameters were glucose, triglycerides, and the triglycerideglucose index.

Results: The visceral abdominal fat (VAF) area and VAF percentage were lower in females compared to the VAF area and VAF percentage in males, (p=0.001, and p<0.001 respectively). However, the total abdominal fat (TAF) area was not significantly different between genders. Visceral fat and triglyceride levels showed a weakly positive connection for females (r=0.447, p=0.002) but not for males (r=0.229, p=0.09). The glucose levels had a weak correlation with CT calculated abdominal fat parameters, with the strongest statistically significant correlation value being with TAF for females (r=0.331, p=0.003).

Conclusions: Areas of abdominal fat compartments correlate with metabolic parameters in the blood, and in the future, their assessment might be considered when constructing risk scores. Visceral fat content assessment for every abdominal computed tomography procedure might become a surrogate marker for cardio-vascular risk estimation after defining clear cut-off values and image analysis parameters.

Castleman’s disease is a benign lymphoproliferative disorder. The coexistence of Hodgkin’s lymphoma and multicentric Castle-man’s disease is a rare phenomenon. We discuss a case of a 48-year-old female patient who had been in the records of the Colentina Hematology Clinic since 2019, with the diagnosis of classic Hodgkin’s Lymphoma, nodular sclerosis type I BNLI, stage IIXB. For this, she underwent 3 courses of ABVD and 2 courses of BEACOPP, without showing complete remission on PET/CT evaluation at the end of treatment. After that, we initiated rescue therapy and performed 4 IGEV courses, followed by autologous stem cell transplantation. For maintenance treatment, we opted for Brentuximab, but it was discontinued after the first administration due to the appearance of adverse reactions. Subsequently, we decided to perform radiotherapy with 20 fractions cumulating a total dose of 36 Gy. Shortly after the radiotherapy, symptoms reappeared which were suspected to be in the context of a relapse of the disease. For confirmatory diagnosis, we performed a new PET-CT which highlighted metabolically active ganglion images. Further, were carried out lymph node biopsy for histopathological and immunohistochemical examinations were carried out. The underlying disease was diagnosed as plasmacytic subtype, HHV8 negative, multicentric Castleman’s disease. For treatment, we relied on administrations of Siltuximab treatment therapy that showed complete remission. Castleman’s disease presents a unique diagnostic challenge, but a confirmatory diagnosis can be based on a biopsy examination, advisable after each relapse.

Published: February 2023

Biomethanation is a prospective biogas upgrading method to integrate renewable energy grid with existing biogas grid. Biomethane can directly substitute fossil natural gas and be used in all energy sectors. The selection of packing material for the ex-situ biomethanation in biotrickling filter reactors can be based on the physical and chemical characterization of the carrier material. The packing material selected for biotrickling filter reactors supports hydrogenotrophic methanogenic growth and thereby increases the area for H2 mass transfer. Chemical components and melting temperature analysis of wood ash material are carried out to determine optimal parameters for producing wood ash filter material. Physical characteristics of new wood ash filter material such as volume-specific surface area (m2 m−3), the external porosity (vol. %) and bulk density (kg m−3) are carried out to compare this material with other carrier materials that have been used in biotrickling filter reactors before.

Statistically significant differences between phytoplankton of the pelagic area and littoral zone, overgrown with macrophytes, were observed in seven reservoirs and three natural lakes. Both total biomass and species diversity of the phytoplankton were higher in the macrophyte settlements than in the pelagic zone. Regarding biomass, the divisions of Pyrrhophyta and Cryptophyta were the main contributors to the similarity of the pelagic areas while the pennate Bacillariophyta were the main contributors to the similarity of macrophyte zones. The phytoplankton structure in the littoral zone differed also within the same water body but in sites with different macrophyte dominant species, as the differences concerned mainly the ratio between pennate diatoms and conjugatophyceans.

The transmission line of 150 kV between GIS (Gas Insulated Switchgear) Bandara Ngurah Rai and GI Nusa Dua needs to be concerned further due to the high number of VIP customers supplied by the GIS Bandara Ngurah Rai. The location of transmission line of GIS Bandara Ngurah Rai with GI Nusa Dua is also located in the southern area of Bali in which according to the data of BMKG in 2018, it was recorded that 15.000-30.000 lightning strike occurred in the southern area of Bali. One of the devices used to protect the equipment from lightning surge is lightning arrester. Lightning arrester which is used in the network of GIS Bandara Ngurah Rai to GI Nusa Dua is placed on Cable head 60. The transmission line of GIS Bandara Ngurah Rai with GI Nusa Dua is connected by an overhead line of 8.5 km and an underground cable of 2.02 km, which is connected by terminating on Cable head 60. The distance between the Airport GIS transformer and the lightning arrester is 2.02 km, therefore it needs to be studied further in order to find out whether the protection generated by the lightning arrester has been optimal or not. The result showed that the arrester with an installation distance of 2020 meters from the transformer is still able to cut the lightning surges by producing the sparkover voltage value of 605.12 kv. Accordingly, the result of sparkover voltage exceeds the sparkover voltage of the arrester in the number of 577kv, however the voltage is still within the tolerance range of the sparkover voltage of the arrester.

Renewableenergy which has been widely used as electrical energy by developed countries is wind energy,in addition to the use of natural wind energy as alternative energy, there is also artificial wind,namely the waste energy from the exhaust fan can be used as a source of energy. analternative energy source option for Wind Power Plant (WPP). The characteristics of the windoutput from the exhaust fan itself spread the wind direction so that the wind energy that can becaptured by the wind turbine is less than optimal, so it is necessary to install a wind tunnel thatis useful for directing or focusing the wind distribution In this study, a wind tunnel has beendesigned which is placed in the direction of the exhaust wind output of the horizontal axis windturbine exhaust fan. With the addition of a wind tunnel, it can increase the wind speed from 3.3m/s to 5.8 m/s or an increase of 76% and power harvesters increase from 0.38 Watt to 0.96Watt or an increase of 153%.

Using neutrophil-lymphocyte ratio, mean platelet volume, and hyponatremia to diagnose appendicitis in children
Authors: Assiri Ali , Alrowabah Norah , Alobaidi Abdulsalam
Published: February 2023

Background: Acute appendicitis is one of the common reasons for acute abdominal pain among children. The diagnosis of appendicitis in children is always challenging. There is a failure to improve morbidity and mortality related to appendicitis, even after advancements in imaging modalities. Therefore, there is a need for markers to help in the diagnosis process. This study aimed at finding if neutrophil to lymphocyte ratio (NLR), mean platelet volume (MPV), and hyponatremia are helpful tools to diagnose acute appendicitis and whether they can be beneficial in distinguishing complicated from uncomplicated appendicitis among children.
Methods: This cross-sectional study was conducted on the pediatric population who were diagnosed with acute appendicitis and treated as an inpatient in the Ministry of Health Hospitals in Abha and Khamis Mushayt. The data of patients were collected using a data collection sheet. Statistical analysis was conducted using the Statistical Package for the Social Sciences software.
Results: Among 384 children with appendicitis; 72.9% had an uncomplicated acute appendectomy, and 27.1% had a complicated condition. NLR significantly increased among complicated cases (p < 0.001), whereas MPV and sodium levels were increased among uncomplicated patients (p < 0.001). The logistic regression model showed that NLR was a predictor for complicated appendicitis (p = 0.031, OR = 1.066; CI 1.006-1.129), whereas regarding increased levels of MPV and sodium, it was found that p = 0.009, OR = 0.794; CI 0.668-0.945 for MPV, and p < 0.001, OR = 0.803; CI 0.735-0.878 for sodium.
Conclusion: NLR, low MPV, and hyponatremia have a role in the diagnosis of complicated appendicitis, and they can be predictors of complicated appendicitis.

INTRODUCTION: Cardiovascular diseases are the main cause of death in patients with type 1 diabetes mellitus (T1DM) and atherosclerotic process begins in childhood. OBJECTIVE: To evaluate lipid profile of patients with T1DM accompanied at the pediatric endocrinology (UEP), Hospital de Clínicas, Federal University of Paraná (HC-UFPR), the prevalence of dyslipidemia and its correlation with glycemic control, duration of T1DM, family history of dyslipidemia and nutritional profile status. METHODS: Data of diagnostic information, comorbidities, birth weight, sex, family history of diabetes, dyslipidemia and heart diseases were reviewed. Anthropometric measurements, glycemic control, blood pressure (BP), lipid profile, and pharmacological treatment for dyslipidemia were obtained in four moments: after three months of diagnosis (t1), two (t2), five (t3), and ten (t4) years of illness. RESULTS: 228 patients (122 girls), mean age at diagnosis of 7.3 years, were included. In t3 and t4 there was a significant increase in BP elevation. Prevalence of dyslipidemia was 31.7% in t1, 33.7% in t2; 37.4% in t3; and in 63.6% in t4. There was a significant increase in total cholesterol and LDL-cholesterol level over time (p<0.001) and a significant increase in triglycerides levels only in t4 (p=0.002). CONCLUSION: Changes in lipid profile in children and adolescents with T1DM are prevalent, but they are undertreated, and the greater age, the greater probability of developing dyslipidemia. Thus, screening for dyslipidemia should be done and pharmacological treatment should be encouraged as recommended.

Authors: Masotti Giulia , Tresoldi Antonia
Published: February 2023

OBJECTIVES: To quantify the proportion of pediatric inpatients eligible for palliative care at the teaching hospital of the University of Campinas (HC/UNICAMP). METHODS: This retrospective descriptive cross-sectional study included pediatric inpatients seen at HC/UNICAMP from June to October 2017. Patients were deemed eligible if they had one of the following underlying conditions at the time of admission: (I) diseases for which curative therapy exists, but may fail; (II) diseases in which premature death is expected, but for which comprehensive care may prolong life with reasonable quality; (III) chronic progressive diseases for which only palliative, potentially prolonged, care is available; (IV) non-progressive neurological disorders that increase the likelihood of premature death. Patients deemed eligible were compared to non-eligible patients based on sex, age, type of admission (emergency/elective), and frequency of readmission. P-values below 0.05 were considered statistically significant. RESULTS: Almost a third (30.9%) of the pediatric inpatients seen at HC/UNICAMP were deemed eligible for palliative care. The demographic profiles of eligible and non-eligible patients were not significantly different. The number of readmissions and emergency admissions of eligible patients was significantly greater than that of non-eligible patients. CONCLUSION: Although challenging, this is a subject that requires more discussion to further improve the overall care provided to pediatric patients.
