Determination of the total content of similar substances using integrated indices or multivariate calibrations at a high intragroup selectivity of signals
Authors: Vershinin V. I. , Abramova A. E. 
Published: October 2022

The total content (cs ) of similar organic compounds is usually determined without their separation by measuring their generalized spectral signals at one or more analytical wavelengths (AW). The resulted es­ timates of cs are approximately adequate if all the sensitivity coefficients of the substances (components of the desired group) are the values of the same order of magnitude. The possibility of a correct assessment of cs with a strongly pronounced intragroup selectivity of signals has not been previously tested. Model hexane solutions of the known composition simultaneously containing mono-, bi-, and tricyclic arenes at сs value about 10-4 mol/dm3were analyzed to verify this variant of the group analysis. At a fixed wavelength, the values of molar absorptivity of arenes with different numbers of rings differ by 2 - 3 orders of magni­tude. Two variants of group analysis were compared: 1) measurement of the generalized signal of arenes at 260 nm with subsequent calculation of the result using univariate calibration in terms of naphthalene or anthracene; 2) measurement of generalized signals for several m wavelengths in the spectral region of 250 - 290 nm with subsequent calculation of the result using the inverted multivariate calibration. The first method (calculation of the integrated index) led to large systematic errors, sometimes exceeding 100 % rel. (in modulus) which appeared insensitive both to the wavelength and to the nature of the stan­dard substance. The second method provided more correct results and even at m = 11 the errors of group analysis did not exceed 10 %. Nevertheless, the errors in the estimation of csdramatically increased if the sample contains components (arenes) of the desired group that were not taken into account when con­structing the inverted calibration. It is shown that with a strongly pronounced intragroup selectivity of signals, group analysis can and should be carried out using inverted multivariate calibrations.

New effective wound healing agents are a priority for modern clinical pharmacology. A promising approach would be to develop medicinal products that promote angiogenesis, which is a critical step in wound healing. The aim of the study was to evaluate the wound healing effect of a medicinal product based on recombinant human angiogenin in gel form in various experimental models. Materials and methods: white outbred male rats were used as experimental ani mals. The study compared healing effects of a regenerating product containing recombinant human angiogenin (0.0025%) in gel form and a reference product in full-thickness excision, incision, and burn wound models. The healing effect of the test product in treating chronic wounds was assessed in a model of alloxan-induced diabetes mellitus. The anti-inflammatory effect of the test product containing recombinant human angiogenin was compared with that of another reference product in a model of adjuvant-induced arthritis. Results: according to the study, the test product based on recombinant human angiogenin exerts higher wound healing effect in treating excision, incision, and burn wounds than the reference product (Solcoseryl gel). Being applied, the test product intensifies tissue repair in chronic wounds in the model of alloxan-induced diabetes. The dissociation of necrotic tissues and the progression towards epithelialisation at wound edges are more rapid. The anti-inflammatory effect of the test product based on recombinant human angiogenin is comparable with that of the reference product (Diclofenac gel). Conclusions: the test product based on recombinant human angiogenin in gel form was found to have pronounced wound healing and anti-inflammatory effects comparable with those of reference products.

Published: October 2022

This article presents the design of a magnetic microactuator comprising soft magnetic material blocks and flexible beams. The modular layout of the proposed microactuator promotes scalability towards different microrobotic applications using low magnetic fields. The presented microactuator consists of three soft magnetic material (Ni-Fe 4750) blocks connected together via two Polydimethylsiloxane (PDMS) semi-circular beams. A detailed design approach is highlighted giving considerations toward compactness, range of motion and force characteristics of the actuator. The actuator displacement and force characteristics are approximately linear in the magnetic field strength range of 80-160 kA/m. It can achieve maximum displacements of 111.6 µm (at 160 kA/m) during extension and 10.7 µm (at 80 kA/m) during contraction under no-load condition. The maximum force output of the microactuator, computed through a contact simulation, was 404.3 nN at a magnetic field strength of 160 kA/m. The microactuator achieved stroke angles up to 18.4 in a study where the microactuator was integrated with a swimming microrobot executing rowing motion using an artificial appendage, providing insight into the capabilities of actuating untethered microrobots.
The potential association of musculoskeletal pain with presenteeism and work engagement among intensive care unit nurses: a cross-sectional study
Authors: BALTA Selin , ALAGÜNEY Mehmet Erdem 
Published: October 2022

Aim: Work-related musculoskeletal disorders and associated musculoskeletal pain among intensive care nurses are important, as these factors may be related to presenteeism and work engagement. The aim of this study was to investigate the potential association of musculoskeletal pain with presenteeism and work engagement among intensive care nurses.
Material and Method: This descriptive study was carried out with members of the Turkish Society of Critical Care Nurses. All the participants completed a questionnaire, which included questions about general demographic data and occupational musculoskeletal exposures (Occupational Safety and Health Administration [OSHA] Ergonomic Assessment Checklist). To measure pain, work engagement and presenteeism, the following instruments were used: The Brief Pain Inventory Short Form (BPI SF), Utrecht Work Engagement Scale (UWES-17) and Stanford Presenteeism Scale-6 (SPS-6). This study was performed in 2021, and the questionnaire was distributed via email to the database of Turkish Society of Critical Care Nurses.
Results: Our study was completed with 153 intensive care unit nurses. Among the study population, 76.5% (n=117) of the nurses had chronic musculoskeletal pain, 80% of whom had exposure to lifting heavy weights. There was a weak negative correlation between pain and work engagement, as shown by the BPI SF pain interference subscale and the vigour subscale of the UWES-17 (p=0.04, r=-.166). There was also a weak negative correlation between pain and presenteeism according to the BPI SF pain interference subscale and SPS-6 (p=0.04, r=-.193). There was no statistically significant association between workplace ergonomic exposures, presenteeism, work engagement and the presence of chronic musculoskeletal pain.
Conclusion: Neither chronic musculoskeletal system pain nor pain intensity was significantly correlated with work engagement, occupational musculoskeletal exposures or presenteeism. However, musculoskeletal pain-related effects on daily activities of living had a negative impact on work engagement (vigour) and presenteeism.
Evaluation of occupational exposure reasons and experiences of nursing students
Authors: TOPÇU Sevcan , EMLEK SERT Zuhal 
Published: October 2022

Aim: The aim of this study was to describe the occupational exposure reasons and experiences of nursing students.
Material and Method: The qualitative research design was used. The participants were selected using the purposive sampling method. The 20 nursing students included in this study. The data was collected at face-to-face interviews conducted during September 2019 and February 2020.
Results: The mean age of nursing students was 21.65±0.91. The majority (85%) of nursing students were women, and 15% were men (n=3). From the interviews, six key themes were identified regarding the nursing students’ experiences of occupational exposure in the last six months: lack of knowledge, inadequate experience, theoretical and practical training loads, inadequate resources, lack of warning and information, and carelessness.
Conclusion: The one of the most important reasons for exposure to occupational hazards is lack of knowledge. Nursing Schools should ensure that nursing students are adequately trained in occupational hazards before their clinical placements.
The outcome of single-visit nonsurgical retreatment and patients’ perception of retreatment: a retrospective cohort study with 1-year follow-up
Authors: ÖZBAY Yağız 
Published: October 2022

Aim: To evaluate the outcome of single visit nonsurgical retreatment by clinical examination and PAI (Periapical Index) and, patients’ feedback regarding the nonsurgical retreatment after 1 year.
Material and Method: 115 patients who previously had nonsurgical retreatment were recalled after 1 year and after dropouts, 84 patients were examined clinically and radiographical examinations were completed pre-and postoperatively using Periapical Index. Patients were also asked if they would still choose nonsurgical retreatment for teeth with previously failed root canal treatment.
Results: The healing rate after 1 year was 88%. The tooth type did not influence the outcome (p=0.756). While the failure rate was lower in males (3.3%) than in females (16.7%), gender did not affect the outcome (p=0.088). 97.6% of patients had a positive approach to nonsurgical retreatment. There was a statistically significant relationship between treatment outcome and patients' feedback (p=0.013). There is a statistically significant positive correlation between postoperative VAS (Visual Analogue Scale) pain score and postoperative PAI score (p=0.002).
Conclusion: Single-visit nonsurgical retreatment is a viable option for teeth where certain periapical diseases such as symptomatic apical abscess are excluded. Patients, who experienced successful nonsurgical retreatment, are eager to preserve their tooth with failed primary root canal treatment when nonsurgical retreatment option is available.
The diagnostic value of complete blood parameters in determining the severity of community-acquired pneumonia in children
Authors: GÜVEN Deniz , KIŞLAL Fatih Mehmet 
Published: October 2022

Aim: In children, community-acquired pneumonia (CAP) has a high mortality and morbidity rate. Platelet, neutrophil, lymphocyte, monocyte, eosinophil, red cell distributions width (RDW), mean platelet volume (MPV), platelet distributions width (PDW), platelet to lymphocyte ratio (PLR), and neutrophil to lymphocyte ratio (NLR) have all been suggested as markers of systemic infection and inflammation. Several research, however, have centered on the clinical significance of blood parameters in pediatric CAP. We aim to determine the diagnostic value of complete blood parameters for CAP and to look into their relationship to disease severity.
Material and Method: A retrospective, the cross-sectional study enrolled children aged 3 months to 18 years who were diagnosed with CAP at Ankara Atatürk Sanatorium Training and Research Hospital's pediatrics clinics between January 2018 and June 2021, as well as age-matched healthy children. CAP case definition was made according to the CAP case definition defined by the World Health Organization (WHO). Patients were evaluated according to the criteria of WHO and British Thoracic Society 2011 guidelines as severe and mild CAP.
Results: 400 CAP and 400 control patients were included in the study. The mean age of the CAP group was 2.40±3.20 years and the control group was 2.38±3.17 years. Eosinophil, hemoglobin, MPV, PDW and PLR values of the CAP group was statistically significantly lower; leukocytes, lymphocyte, monocyte, neutrophil, basophil, platelet, RDW, and NLR levels of the CAP group were higher than the control group (p

Published: October 2022

Aim: Closed reduction plaster casting (CRPC) and percutaneous pinning (CRPP) remain an important treatment modalities for extra-articular distal radius fractures especially in elderly patients. These two treatment methods have advantages and disadvantages compared to each other. The ideal treatment of extra-articular distal radius fractures is still debatable. We aimed to retrospectively evaluate the clinical and radiological results after CRPC and CRPP for the treatment of distal radius fractures in the patient population over 65 years of age.
Material and Method: Between 1 January 2015 and 1 January 2019, patients older than 65 years of age who presented with extra-articular noncomminuted distal radius fractures were retrospectively evaluated. 95 patients diagnosed with distal radius fracture were separated into 2 groups, who were administered the following: CRPC (n:51), CRPP (n:44). We compared the characteristics of the patients, the mechanisms of injury, fracture types and treatment methods, pre-reduction and post-reduction radiological parameters and clinical functions for the two groups. Volar tilt, radial inclination, ulnar variance, and radial length were compared. Clinical results were also compared.
Results: The mean follow-up period was 19.8 months (range, 12-29 months; SD=11.0) in the CRPC group and 18.6 months (range, 12-26 months; SD=10.9) in the CRPP group. Mean range of motion and grip strength were maintained in both treatment groups at one-year follow-up. There was no statistically significant difference between the groups (p>0.05). There was no statistically significant difference between the groups in terms of the scores evaluating the daily activity, pain and mental status of the patients after the treatment (p>0.05). There are no statistically significant differences between fixation with CRPC and CRPP in terms of clinical and radiological results (p>0.05).
Conclusion: Closed reduction plaster casting and closed reduction percutaneous pinning are equally effective in the treatment of extra-articular distal radius fractures in the elderly.

Published: October 2022

Introduction: Micro V Doppler is a different technique from the conventional Doppler US method, which reveals the small vessel structure developed in recent years. We planned to reveal whether there are significant difference between spermiogram test, scrotal US, Micro V Doppler and international erectile function form questionnaire results between patients who had recently COVID-19 and the control group.
Material and Method: Our study included 45 patients who had recently had COVID-19 infection, and 45 control patients. Spermiogram test, scrotal US, Micro V Doppler and erectile dysfunction score, orgasmic function score, sexual desire score, sexual satisfaction score, and general satisfaction scores were evaluated for our patients and control groups included in our study.
Results: On scrotal US, there was no sequelae in the parenchyma in all patients (n=45, 100%) who had experienced COVID-19. When the spermiogram tests of the control group and our patients with COVID-19 infection were compared, the presence of oligozoospermia, leukocytospermia and other abnormal positive findings was similar between the two groups (p>0.005). Micro V Doppler findings of the control group and our patients who did not have COVID-19 infection were similar. Sexual Desire and sexual satisfaction scores of patients with COVID-19 were significantly lower than the control group without COVID-19 infection (p

Published: October 2022

Background: Tooth loss is closely associated with Alzheimer’s disease (AD). Previously, we reported that tooth loss induced memory impairment in amyloid precursor protein knock-in mice by decreasing neuronal activity and synaptic protein levels and increasing glial activation, neuroinflammation, and pyramidal neuronal cell loss without altering amyloid-β levels in the hippocampus. However, the effects of tooth loss in young wild-type mice have not been explored yet. Objective: We investigated the effects of tooth loss on memory impairment, neuronal activity, synaptic protein levels, glial activation, and pyramidal neuronal cell loss in young wild-type mice. Methods: Two-month-old wild-type mice were randomly divided into control and tooth loss groups. In the tooth loss group, maxillary molar teeth on both sides were extracted, whereas no teeth were extracted in the control group. Two months after tooth extraction, we performed a novel object recognition test to evaluate memory function. Glial activation, neuronal activity, synaptic protein levels, and the number of pyramidal neurons were evaluated using immunofluorescence staining, immunohistochemistry, and western blotting. Results: The tooth loss group exhibited memory impairment and decreased neuronal activity and the levels of synaptic proteins in both the hippocampus and cortex. Moreover, tooth loss increased the activation of phosphorylated c-Jun N-terminal kinase (JNK), heat shock protein 90 (HSP90), and glial activation and reduced the number of pyramidal neurons in the hippocampus. Conclusion: Tooth loss in the young wild-type mice will attenuate neuronal activity, decrease synaptic protein levels, and induce pyramidal neuronal loss, and eventually lead to memory impairment.
When did post-truth begin? From climate change denial to war-mongering nationalism
Authors: Conversi Daniele 
Published: October 2022

This article argues that the media structure created by the framework of climate denial in the 2000s was foundational in the subsequent SYSTEMATIC use and DIFFUSION of FAKE NEWS and ‘post-truth’, culminating around the Copenhagen agreement in 2009. The article therefore places the negation of climate change at the roots of the persisting appeal of fake news.

The shell-shocking discovery that fake news travels much further, and faster, than real news (Vosoughi, Roy et al. 2018) has thus deeper social, political, economic, health, medical, and life-changing implications than everything else that has been said about these fields taken together: All societies are based on TRUST and the circulation of reliable information. If systematic misinformation prevails, societies tend to break down at various levels, from the individual to the national and the supranational.

On the other hand, few have speculated on how the phenomenon was shaped by nationalist ideology, even though it was clearly identified as originating from far-right agendas.

I therefore argue that two variables must be jointly investigated to explain the appearance of nebulous post-truth politics: the denial of climate change and state-led nationalism, the former supported by the latter.

Thus, the origin of post-truth needs to be connected to the campaign of misinformation initiated with climate change denial around the Copenhagen accord — and, earlier in the USA.

This approach brings us nearer to finding a series of solutions for rebuilding public trust: if trust in science is not promptly re-established, then the very basis of modern societies can easily collapse bringing down with them everyone else.
