Accuracy Assessment of Low Cost UAV Based City Modelling for Urban Planning

This paper presents an Unmanned Aerial Vehicles (UAV) based 3D city modelling approach to be used in managing and planning urban areas. While the urban growth is rapidly increasing in many places of the world, the conventional techniques do not respond to the changing environment simultaneously. For effective planning, high-resolution remote sensing is a tool for the production of 3D digital city models. In this study, it is aimed at designing the remote sensing by UAV through urban terrain. Using all the information produced from UAV imagery, high-accurate 3D city models are obtained. The analysis of XYZ data of the derived from 3D model using UAV photogrammetry revealed similar products as the terrestrial surveys which are commonly used for the last development plans and city maps. The experimental results show the effectiveness of the UAV-based 3D city modelling. The assessed accuracy of the UAV photogrammetry proved that urban planners can use it as the main tool of data collection for boundary mapping, changes monitoring and topographical surveying instead of GPS/GNSS surveying

Desfluran anestezisi sonrası karaciğer toksisitesi: olgu sunumu ve gözden geçirme

Geleneksel inhalasyon anestezik ajanların ılımlı ve bazen de şiddetli karaciğer yetmezliğine yol açtıkları müşahade edilmiştir. Ancak yeni inhalasyon ajanları primer hepatotoksisitenin nedeni olarak kabul edilemezler. Bu olgu sunumunda laparoskopik kolesistektomi planlanan hipertansiyonu, peptik ülseri ve hiperlipidemisi olan ASA II, 65 yaşında kadın hastada desflurana bağlı karaciğer yetmez- liğini tanımladık. Preoperatif laboratuar değerleri normaldi. Operasyon esnasında, midazolam, remifentanil, sodyum tiyopental ve vekuronyum devamında da desfluran anestezisi uygulandı. Peroperatif 4L CO2 ile CO2 insuflasyon basıncı 15 mmHg’da tutuldu. Per operatif hastanın hemodinamik parametreleri stabil olarak dökümante edildi. Laparoskopik kolesistektomi operasyonu 135 dakika sürdü. Serum alanin aminotransferaz ve aspartat aminotransferaz düzeyi postoperatif 2. günde sırasıyla 711 ve 621 U/L idi. Karaciğer enzimleri postoperatif 13. günde normale döndü ve hasta 15. günde taburcu edildi. Biz hepatotoksisiteyi bir önceki anestezi uygu- lanması sonrası, operasyonda uygulanan desfluran ile ilişkilendiriyoruz. Gelecekte hasta anestezi alacaksa total intravenöz anestezi uygulanabili

Relationship between food insecurity and geriatric syndromes in older adults: A multicenter study in Turkey

Aims: In this study, the aim was to determine the prevalence of geriatric syndromes such as frailty, sarcopenia risk and malnutrition in older adults and to investigate the relationship between food insecurity, and frailty, risk of sarcopenia and malnutrition. Methods: The study was cross-sectional. It was conducted between February 2022 and June 2022 with 707 older adults. The data were collected through the face-to-face interview method with a questionnaire including the Descriptive Information Form, Household Food Insecurity Access Scale (HFIAS), Frail Scale, Sarcopenia Risk Screening Scale (SARC-F) and Mini Nutritional Assessment-Short Form (MNA-SF). Numbers, percentages, mean, standard deviation, Pearson chi-square test and binary logistic regression analysis were used in data analysis. Results: In the present sample, 30% of the participants experienced some degree of food insecurity. The prevalence of frailty, sarcopenia risk, and malnutrition in the participants was 15.3%, 19.5%, and 1.3%, respectively. We determined that food insecurity was not associated with pre-frailty/frailty and sarcopenia risk. After adjusment for potential counfounders moderate and severe food insecurity was associated with higher odds of malnutrition risk and malnutrition (AOR: 2.06, 95% CI: 1.21–3.51, p:0.007). Conclusion: While food insecurity is not associated with pre-frailty/frailty and sarcopenia risk, moderate and severe food insecurity is a modifiable risk factor for malnutrition risk and malnutrition. Thus, economic and social policies to eliminate food insecurity should be implemented, and efforts to prevent food insecurity should be planned through inter-sectoral cooperation

Effects of Cyclamen trochopteranthum on hepatic drug-metabolizing enzymes

The modulatory effects of the Cyclamen trochopterantum tuber extract on hepatic drug-metabolizing enzymes, including aniline 4-hydroxylase (A4H; CYP2E1), ethoxyresorufin O-deethylase (EROD; CYP1A), methoxyresorufin O-demethylase (MROD; CYP1A), caffeine N-demethylase (C3ND; CYP1A2) aminopyrene N-demethylase (APND; CYP2C6), and erythromycin N-demethylase (ERND; CYP3A1), were examined in vivo in rats. The activities of all of these enzymes were induced by the cyclamen extract. In addition, Western-blot and RT-PCR results clearly showed that CYP2E1, CYP1A1/CYP1A2 and CYP2C6 protein and mRNA levels were substantially increased by four different doses of cyclamen. Although, the CYP3A1 protein level was increased significantly, the mRNA level was not changed. These results indicate that cyclamen tuber extract might have a potential not only to inhibit and/or induce the metabolism of certain co-administered drugs but also influence the development of toxicity and carcinogenesis due to the induction of the cytochrome P450-dependent drug-metabolizing enzymes

Comparison of posterior cranial fossa morphometric measurements in Chiari type I patients with and without syrinx cavity on magnetic resonance imaging

Purpose: To compare the posterior fossa measurements of Chiari type I malformation (CHM1) patients with and without syrinx and with a control group. Material and methods: The patients with syrinx were divided into 2 groupd according to syrinx width/cord width (S/C) ratios: group 1 – S/C ratio 50%. The length of the clivus, the AP length of the foramen magnum, the AP length of the posterior fossa, the perpendicular distance between the McRae line and (a) the splenium of corpus callosum, (b) the pons, and (c) the fastigium of the 160 patients and of the 160 control patients were statistically compared. In addition, the measurements of the patients with and without syrinx, according to the S/C ratio, were statistically compared. Results: Syrinx was present in 59 (36.8 %) of the 160 patients. The S/C ratio was 50% in 29 (49.1%) of them. All the measurements in the patient group, except of the AP length of the foramen magnum, were statistically significantly lower than in the control group (p = 0.001). There was no signif icant difference in the measurements of the patients with syrinx group 1 and the patients without syrinx, but the AP length of posterior fossa was statistically significantly lower in the patients with syrinx group 2 than the patients without syrinx (p = 0.03). Conclusion: The S/C ratio can be a guide to the underlying aetiology

Polyclonal outbreak of bacteremia caused by Burkholderia cepacia in the intensive care unit

Aim: Burkholderia cepacia is a multidrug-resistant, opportunistic pathogen of humans and outbreaks of infection in hospitals have been described. In this study, we aimed to report an outbreak in patients without cystic fibrosis or chronic granulomatous disease involving different species of Burkholderia cepacia. Material and Methods: A small outbreak of nosocomial Burkholderia cepacia complex occurred in a 6-bed intensive care unit. We isolated Burkholderia cepacia from blood cultures of the patients admitted to our intensive care unit. All isolates from patients and the environment were identified by standard microbiological techniques and VITEK system. Antibiotic susceptibility testing was performed using Kirby Bauer's disk diffusion method and the VITEK system Results: All isolates exhibited identical patterns of antibiotic susceptibility and all isolates were sensitive to trimethoprim-sulfamethoxazole, ceftazidime and meropenem. The isolates were typed using pulsed-field gel electrophoresis using the restriction enzymes XbaI and SpeI. Accordingly, while 4 strains were similar, one was different. Discussion: The experience from this outbreak reminded us of the importance of outbreak investigation in such small outbreaks and keeping the health care workers educated and constant attention on this issue. The results of this study emphasized once again the necessity to maintain our sensitivity to the basic principles of sanitation and to raise our awareness of such outbreaks

Fatal child abuse-maltreatment syndrome; a case report

Abstract: Child abuse-maltreatment syndrome can be described as child death due to repeated episodes of physical abuse and neglect. Here we present a case of child physical abuse and neglect causing death due to duodenal perforation. A five year old boy was reported to have stomachache occurring one day before death. He was admitted to a private health clinic where he was discharged after an analgesic injection. Because of increasing complaints he was applied to the same clinic, afterwards sent to an Emergency Department where he died during resuscitation. At autopsy, external examination revealed several traumatic injuries and two bite marks of different age, while internal examination revealed 500 ml of dirty yellowishgreenish free liquid in abdominal cavity and a perforation 0.5 cm in diameter of the duodenum wall. Insufficient parental supervision in spite of continuous traumas strongly indicates negligence or intentional abuse by parents. Additionally, insufficient medical follow up, besides; not disclosing the injuries on child's body adds medical malpractice aspect to this case. Key Words: child abuse-maltreatment syndrome, physical abuse of child, child neglect, domestic violence, death A s a recently recognized entity, Child abuse-maltreatment syndrome involves repeated episodes of intentional trauma and negligence of a child, which can result in chronic consequences or death. This syndrome includes a combination of maltreatment types. Examinations of such cases reveal various types of injuries of different age. In most cases, healed older injuries and findings of negligence are accompanied by a recent fatal injury that is the immediate cause of death Inflicted traumatic brain injury is the leading cause of death due to child abuse, while blunt abdominal trauma takes place as the second commonest cause of death among abused children. Duodenal injuries secondary to blunt trauma are rare but generally life threatening A case of death due to child abuse-maltreatment syndrome with multiple types of maltreatment is presented because of its interesting history and dramatic findings accompanied by medical malpractice. Case presentation The presented case, a five year-old boy, was previously diagnosed with mental retardation, attention deficit and hyperactivity disorder and had rehabilitation because of these issues. He had been followed up in a rehabilitation service until the family terminated the treatment. The subject was separated from his biological mother and had been living with his biological father, step mother and two step-siblings wh
