Published: December 2018

The use of social media in scholarly communication has grown in recent years, and consequently, scholars’ uses of social media has gained importance as a research topic.The aim of this article is to shed light on the role of social media in scholars’ work. The research presents findings from a survey (N=528) conducted in Finland in late 2016. There exists no prior research on the role and uses social media among Finnish scholars. This research specifically focuses on the perceived role of social media in information seeking and sharing. We also study the differences between disciplines, age groups, and positions. Results show that scholars do not perceive social media as being central for their or information seeking and sharing, and that social media services are not replacing traditional publishing forums. Scholars do appreciate the social media services intended and developed for academic use, and find them as having value for their work than general social media services. However, according to our results, social media services have a marginal role in scholars’ information seeking and scholars infrequently share their readings in social media platforms. Some disciplinary differences existed, but there was no connection between scholars’ age or position and the role of social media. Our study shows that the role of social media in academic work and scholarly communication is still rather small. Further research is needed to find out what are the reasons for scholars lack of interest towards social media.
Poikittaistukemattoman paarteen stabiilisuus
Authors: Haapanen Tuomas , Laine Ville , Pajunen Sami
Published: December 2018

Tämän artikkelin tarkoitus on esitellä, miten poikittaistukemattoman paarteen nurjahduspituus voidaan määrittää hyödyntämällä ristikkorakenteen stabiloivia osia. Poikittaistukemattomalla paarteella työssä tarkoitetaan puristettua ristikkopilarin sisä- tai kattoristikon alapaarretta. Näissä tapauksissa on perinteisesti käytetty erillistä nurjahdustuentajärjestelmää, jotta nurjahduspituutta tasosta poispäin on voitu pienentää. Kuitenkin, vaikka sisä- tai alapaarre on kokonaan ilman erillistä poikittaistuentaa, voidaan nurjahduspituutta redusoida selvästi, jopa arvoon 0,3…0,4*L, jossa L on paarteen pituus. Tämä perustetaan siihen, että ristikkoa hyödynnetään kokonaisuutena ja otetaan huomioon uumasauvojen taivutus- ja liitosjäykkyydet sekä tukevan/vedetyn paarteen vääntöjäykkyys.

In this study isolated 100 adult female of local black goat (Capra hircus) examined in spring and fall season for Tick and Lice investigations, then divided into two groups: 50 infested goats with ectoparasite and 50 non-infested goats. Three species of ticks (Rhipicephalus sanguinus, R. turanicus and R. bursa) and one species of lice (Bovicola caprae) were observed. Biochemical values (serum proteins and some trace elements) analyzed, in infested goats emerges decline in serum protein value 7.12±0.08 µg/dl, albumin value 4.12±0.03 µg/dl and increase of globulin value 3.04±0.09 µg/dl, in serum protein and globulin values shows not significance differences, while described highly significance differences in albumin value at p?0.01, when compared to control goats. In trace elements decline of zinc level 48.97±1.20 µg/dl and copper level 114.15±3.75 µg/dl levels with a highly significant differences at p?0.01 in infested goats when compare to control goats. It is observed that mixed infestation has much effects than tick or lice infestation on goats, which led to reduction in serum protein value 6.89±0.20 µg/dl, albumin value 4.11±0.09 µg/dl and raise in globulin value 3.10±0.11 µg/dl without any significance differences, also noticed insignificant declines in zinc level 45.67±2.40 µg/dl, while decrease in copper level 99.33±9.86 µg/dl significantly at p?0.05.

Rare malignant skin tumours of the head and neck
Authors: Oroz Aleksandar , Bokun Zorana , Lazović Biljana , Čukić Ognjen , Valjarević Svetlana
Published: December 2018

Introduction: Malignant skin tumors in the majority of cases arise from the squamous epithelium, although they may occur in other accompanying skin structures, such as skin adnexa (hair follicle, sweat and sebaceous glands), as well as soft tissues participating in the building of skin structure, such as muscles, fibrous, fatty tissue and cartilagå. Those tumors may also have a neuroendocrine origin or may arise from a premalignant lesion (solar keratosis and lentigo maligna). Regardless of their origin, they usually present as a nodule or longstanding, non-healing ulceration. Their early recognition enhances the treatment results and decreases the possibility of complications (invasion of deeper tissue structures and occurrence of regional and distant metastases). Material and methods: Our retrospective study included 100 patients of both sexes surgically treated for skin malignancy in the Department for Otorhinolaryngology and Maxillofacial surgery of the Clinical Hospital Centre "Zemun" , Belgrade, Serbia. The goal of this paper is to highlight the frequency of rare malignant tumors compared to the more frequent ones and consider the most appropriate clinical-diagnostic approach as well as the treatment modality for the patient. Conclusion: Our study has shown that the most frequent tumor of the head and neck skin is basal cell carcinoma.

Objective. To study the effects of regular physical activity on the morphological, physiological and body composition parameters of overweight and obese adolescents. Methods. We conducted an experimental study with30 adolescents divided in two according to their body mass index. The group 1 was composed of overweight subjects with a body mass index between 25-29.9 kg/m2 , and group 2 obese subjects with a body mass index 30 kg/m2 subjected to a program of adapted physical activity associated with a low-calorie nutrition education low in cholesterol and in saturated fatty acids (bad fats), low-fat rich in vegetables, fruits and vitamins for a period of six months. Results. This study reveals that after six months of intervention, overweight subjects significantly decreased waist circumference (82.9 ± 4.2 cm before versus 77.6 ± 4.6 cm after), heart rate (86.8 ± 3.6 beat/min before versus 81.4 ± 3.8 beat/min after), total fat (32.2 ± 1.8% before versus 27.2 ± 1.5% after), visceral fat (16.6 ± 2.3% before versus 11.1 ± 2.5% after), and decreased muscle (15.6 ± 2.7% before versus 19.4 ± 4.1% after), while obese subjects significantly decreased waist circumference (88.9 ± 6.2 cm before versus 85.8 ± 5.9 cm after), visceral fat (17.4 ± 3.2% before versus 14.1 ± 3.1% after), respiratory capacity (61.1 ± 2.7% before versus 65 ± 2.1%). In addition this study reveals that overweight subjects compared to obese subjects more changed their waist circumference (77.6 ± 4.6 cm for overweight versus 85.8 ± 5.9 cm for obese), body mass index (24.9 ± 4.1 kg/m2 for overweight versus 28.8 ± 1.2 kg/m2 for obese), heart rate (81.4 ± 3.8 beat/min for overweight versus 28.8 ± 1.2 beat/min for obese), visceral fat (11.1 ± 2.5% for overweight versus 14.1 ± 3.1% for obese), and muscle (19.4 ± 4.1% for overweight versus 17.1 ± 2.1%). Conclusion. Obese adolescents have by means of regular activity significantly changed their morphological, physiological and body composition parameters of overweight and obese

Published: December 2018

Objective: The aim of this study was to investigate the correlation of temporomandibular joint disorders (TMD) and neck structure changes in adolescents with idiopathic scoliosis (IS) by clinical examination. Material and Methods: The study included 51 patients affected by IS (24 males, 27 females; mean age: 13.5 ± 2.1 years) selected using simple random sampling, and a healthy control group of 50 subjects (23 males, 27 females; mean age: 14.5 ± 2.3 years). The Diagnostic Criteria for Temporomandibular Disorders: Clinical Protocol and Assessment Instruments (DC/TMD) form was utilized to assess the signs and symptoms of TMD in the subjects. For the evaluation of neck structures, masseter and temporalis muscles, pressure pain threshold (PPT) values were measured with a hand-held pressure algometer. Obtained data were analyzed statistically applying Mann-Whitney U test, Wilcoxon, and chi-squared tests with a significance level of 0.05. Results: According to the DC/TMD form, the following parameters showed statistically significant differences between the groups (p 0.001): presence of TMD, temporal headache, midline deviation, and right and left lateral movements. The PPT values were higher in the control group compared with the study group (p < 0.001). Additionally, the type of pain-related TMD identified in the subjects was myalgia. The myalgia was significantly (p < 0.001) higher in the study group (68.6%) than in the control group (22%). Conclusion: This study concluded that spinal diseases which cause postural changes, like IS, in the head and shoulder region are associated with muscle adaptation and alterations in the temporomandibular joint area.

Published: December 2018

Objectives: This study aimed to evaluate whether placing a threaded plug in the hole of a locking plate at the fracture level is beneficial for increasing the resistance of the plate. Methods: This experimental study analyzed load and compression forces in sheep tibia bone models. The following groups were assessed: Group 1 (n = 4), control bone samples; Group 2 (n = 4), samples of screw plate fixation without threaded plug in the hole at the fracture level; and Group 3 (n = 4), samples of screw plate fixation with a threaded plug in the hole at the fracture level. Elastic force, bending moment, elastic compression, and rigidity were evaluated using a three-point bending test. Results: Group 1 showed the greatest elastic force and the least amount of compression. The rigidity and elastic force were better in Group 3 than in Group 2. The mean elastic force in Group 3 was 22.4% of that in Group 1, whereas the mean elastic force in Group 2 was 19% of that in Group 1. Rigidity in Group 3 was 24.7% of that in Group 1, whereas rigidity in Group 2 was 18.3% of that in Group 1. Improved results were obtained in Group 3 when compared with Group 2. Conclusions: Our results suggest that placing a threaded plug in the hole of the plate at the fracture level provides additional rigidity and stability by improving resistance to loading forces, but the differences were not statistically significant.
Severe pneumonia caused by antipsihotic drugs: What does not suit, the patient or the drug?
Authors: Lazović Biljana , Blazić Ivana , Zlatković-Svenda Mirjana , Žugić Vladimir
Published: December 2018

Introduction: Antipsychotic drugs are generally categorized as typical antipsychotics (sometimes referred to as first-generation or conventional antipsychotics, or neuroleptics) and atypical antipsychotics; both are approved for the treatment of acute and chronic psychoses (i.e, schizophrenia), mania, agitation, and other psychiatric disorders. In 2005 the US Food and Drug Administration issued a warning about the increased risk of all-cause mortality associated with atypical antipsychotic use in elderly patients with dementia. Community acquired pneumonia (CAP) was one of the most frequently reported causes of death. The same warning was extended to typical antipsychotics in 2008 with extension to people with or without dementia. Case report: We present a 65-year-old Caucasian woman who was admitted to hospital due to massive pneumonia. She was suffered forschisophrenia 15-years and at moment of admission she was in remission. She had continuously high fever up to 40 degrees. All collected cultures (blood, sputum, urine, smear of aspirating catheter) were negative. She was treated with various antibiotics without improvement. After changing antipsychotic drugs, she showed slow improvement until total recovery after 3 months. Discussion and conclusion: Antipsychotic-associated CAP seems to be a clinically relevant issue in frail elderly patients, as consistently documented in several epidemiologic investigations. No clear evidence exists for an increased risk of pneumonia in younger patients treated with antipsychotics. In elderly populations, the increase in risk is dose-dependent, and is more pronounced in the early phases of treatment. Future studies should better define the mechanism underlying antipsychotic-induced pneumonia and identify subgroups of antipsychotic users at higher risk of developing pneumonia.

Published: December 2018

Introduction: Adequate nutrition is necessary to prevent muscle wasting in critically ill patients. Decision about enteral or parenteral nutrition is always questionable. Objective: The aim of our study was to assess the impact of nutrition on muscle wasting in critically ill patients with trauma injury. Material and methods: The study was conducted in the period from January to December 2017 and included 30 critically ill patients with trauma injury hospitalized on the Intensive care unit (ICU) of the University clinic for anesthesiology and intensive care in Skopje. Included patients were divided into two groups: group E - patients where enteral nutrition was conducted after the third day of their admission in ICU and group P - patients where total parenteral nutrition was implemented in the first 24 hours of their admission. The study monitored the impact of two different types of nutrition on muscle wasting evaluated by ultrasound measurements of m.quadriceps femoris thickness and biochemical measurements of the serum creatinine level. Results: In group E there was statistically significant muscle wasting evaluated by ultrasound between the1st and the 3rd and the1st and the 7th day. Difference in measured muscle thickness was 1.90 ± 1.49 mm between the 1st and the 3rd (p = 0.015) and 4.46 ± 2.81 mm between the 1st and the 7th day (p = 0.006). In group P muscle wasting in the same period was without statistical significance. Both groups showed statistically significant decrease in serum creatinine levels between the 1st and the 3rd (p = 0.003, p = 0.03) and the 1st and 7th (p = 0.003) day. The values of differences between the 1st and the 3rd and the 1st and the 7th day were 7.57 ± 4.12 mg/dl and 10.71 ± 5.79 mg/dl in group E and 11.43 ± 10.66 mg/dl and 15.28 ± 8.28 mg/dl in group P. Conclusion: In our study we determined a significant decrease of muscle mass evaluated by ultrasound measurements of m.quadriceps femoris thickness in patients with enteral nutrition after the third day.

Published: December 2018

Objective: The aim of present study was to examine whether there is a difference in parenting motives between patients diagnosed with depression and control groups (non-depressed). Material and Method: The survey included 66 patients who were treated at the Psychiatric Hospital in Novi Pazar (average age = 44.64, SD = 10.00) and 65 subjects who were not diagnosed with depression (average age = 42, SD = 13.05). Participants volunteered to participate in the research and received no compensation for their participation. Respondents were given a Parent Motivation Scale. Results: Results showed that participants in our study are motivated for parenthood mostly by instrumental motivation, altruistic and fatalistic motivations are equally present, and narcissistic motivation is the lowest. Instrumental, fatalistic and altruistic motives for parenting are significantly lower in group consisted of depressed patients. There was no difference in narcissistic motivation between two groups. Conclusion: This finding can be seen in the light of the general condition and the characteristic of people suffering from depression. In them, namely, all aspects of motivation are reduced and it is not surprising that this is so with the motives for parenting.

Introduction: Previous studies showed that refugee status have been associated with various deteriorated effects on human health including higher prevalence of hepatitis B, C and HIV infections. In this study we aim to bridge the gap between Afghan immigrants and naive Turkish population by identifying HBV, HCV and HIV profiles. In addition, a large number of laboratory parameters was collected for all participants, including hematologic and biochemical test results. Materials and Methods: We performed a retrospective review of laboratory records at a tertiary center in Northern Turkey from January 1, 2018, to April 15, 2018. Our population based study comprising hospital data of 403 Afghan refugees and 400 naive Turkish citizens. Results: Afghan refugees had higher anti-HIV seropositivity than Turkish citizens (p < 0.05). There were no difference between the two groups according to HbsAg and anti-HCV seropositivity. Also Afghan refugees had statistically lower ALT levels, higher hemoglobin levels and higher mean TSH level (p < 0.05). Mean T4 level did not show significant difference between the two groups. Conclusion: We need further investigations to find out the risk of infections that originated from immigration.
Vaginal hysterectomy compared to abdominal and laparoscopic hysterectomies in patients without uterine prolapse
Authors: Birsen Bilge , Ayse Zehra , Pervin Karli , Idris Kocak
Published: December 2018

Introduction: Except for the uterine prolapse indication, vaginal hysterectomy has been less popular than abdominal hysterectomy because the latter is considered safer and easier and surgeons often lack sufficient experience on the former. This study aims at comparing a group of patients without prolapse who underwent vaginal hysterectomy to another group of patients who underwent abdominal and laparoscopic hysterectomies with respect to intraoperative and early postoperative complications. Materials and Methods: We retrospectively reviewed the files of patients who presented to the gynecology outpatient clinic of Ondokuz May2s University (OMU), Turkey, between January 2013 and February 2018 and for whom hysterectomy was decided due to benign indications other than uterine prolapse. A total of 105 patients, 35 from each of the groups who underwent abdominal, laparoscopic and vaginal hysterectomies, were included in the study. The vaginal hysterectomy group was compared to the abdominal and laparoscopic hysterectomy patient groups with respect to duration of operation, decrease in hematocrit, blood transfusion, duration of hospitalization, hospital expenses, postoperative pain, wound site infection, and complications of intestine, bladder and ureter. Results: No statistically significant differences were found between the demographic characteristics of the groups. Vaginal hysterectomy was shown to be superior to laparoscopic and abdominal hysterectomies with respect to mean duration of operation (p < 0.005), decrease in hematocrit showing the amount of bleeding (p < 0.005), duration of hospitalization (p < 0.005), hospital expenses (p < 0.005) and amount of postoperative analgesic need (p < 0.005). Wound site infection was found more in abdominal hysterectomy than in vaginal and laparoscopic hysterectomies (p < 0.005). No statistically significant difference was found between vaginal, abdominal and laparoscopic hysterectomies with respect to blood transfusion and complications of intestine, bladder and ureter (p > 0.005). Conclusion: The most important factor in choosing a hysterectomy method is the experience of the surgeon. However, vaginal hysterectomy should be the primarily preferred method, if possible, for being more advantageous in many respects.

Published: December 2018

Objective: Electrosurgery is widely used in surgical procedures, but mainly for subcutaneous and deep layer dissections. The aim of this study was to clinically evaluate the results of routine use of electrosurgical microneedle in performing skin incisions in the facial regions. Material and methods: Eighty patients with both benign and malignant skin lesions in the facial regions undergoing surgery were enrolled in this study. In group A comprising 40 patients, cold steel surgical scalpel N° 15 was used for the surgical procedure. Electrosurgical microneedle with 0.06 mm tip radius and generator unit KLS Martin Electrosurgical Unit ME MB 2 set on cutting mode, power 12 W was used for performing the surgery in group B including the same number of patients. Differences between incision time, excision time, blood loss and the wound related complications were evaluated. Results: The two groups did not significantly differ in the speed of incision and speed of excision although both the speed of incision and the speed of excision were found to be slightly faster in the electrosurgery group. There was significantly less blood loss in the electrosurgery group compared with the scalpel group.Statistical analysis did not confirm as significant the difference in complications between the two groups although most of the complications were associated with the patients operated with scalpel. Conclusion: Electrosurgery presents safe and effective way of work. In that manner, it is very important to choose the right generator unit's settings and the right type of electrode.

Sugammadex is a cyclodextrin molecule that is consisted of bounded sugar molecules. Given its chemical structure, sugammadex may increase blood glucose levels. We aimed to investigate the effect of sugammadex on blood glucose and compare sugammadex to the conventional reverse agent Neostigmine. Methods: Sixty patients undergoing abdominal surgery under general anesthesia were included in this study. The patients were randomly divided into two groups: Group N (n = 30) and Group S (n = 30). At the end of the surgery 50 g/kg Neostigmine and 20 g/kg atropine was administered for the patients in Group N and 2 mg/kg sugammadex was administered for the patients in Group S. Blood glucose levels were measured at 15 minutes before (T1) and at 30th minute of surgery (T2). Blood glucose levels were recorded 30 minutes (T3), 2 hours (T4) and 4 hours (T5) after administration of the reversing agent. Results: Blood glucose levels that were measured at T3, T4 and T5 were significantly higher in Group S compared to Group N (p < 0.05). We consider that sugammadex contains glucose molecules and does not bind to plasma proteins, may cause an increase in blood glucose level and this increase may be associated with chemical structure of sugammadex rather than surgical stress.

The status of specially protected natural areas im-plies, on the one hand, their recreational purpose, and on the other hand, the prevention of adverse man-induced impacts that, in particular, may be a consequence of recreational activities within the protected areas. Justification of the fee for visiting such areas is both an environmental economic and a social task. An economic and mathematical model is proposed to describe the change in the number of visitors to the protected areas and the value of dam-age from man-induced impacts. Land remote sens-ing data are used to identify the properties of the model. The computational experiment results show that the number of visitors to the protected areas recovers over time while the amount of accumulated damage decreases if the fees increase and money is spent on compensation and prevention of damage from man-induced impacts. However, the composi-tion of vacationers may change due to reduced availability of tourist and recreational services for weaker segments of the population. Nowadays, the model proposed can be used to substantiate the development scenarios for tourist and recreational activities in specially protected natural areas. To make precise forecasts, it is necessary to involve land remote sensing data covering a longer period (up to 10 years) as well as data from social networks and land-related forums.
