Analysis of Substance Use and Mental Disorder Diagnoses in Adolescents With a History of Delinquency: a Cross-Sectional Study
(Springer, 2024) Dikeç, Gül; Dikec, Gul; Tas Soylu, Gulsenay; Bilac, Oznur; Uzunoglu, Gulcin; Ayakdas Dagli, Dilek; Hemşirelik Bölümü
This study aimed to evaluate substance use and comorbid mental disorders in delinquent adolescents presenting to a child and adolescent psychiatry outpatient clinic. This study included 47 adolescents aged 15-18 years and had a history of delinquency. Data were collected using the Addiction Profile Index Adolescent Form (API-A) and an information form. Results indicated that the adolescents' mean age is 16.11 +/- 1.05 years, 78.7% had committed crimes against property and 34.0% against the person, and 34.0% were also victims of crime. Mean API-A total scores indicated that their level of substance use was low. In addition, mean API-A total scores showed significant differences according to the adolescents' migration status, age, economic status, school attendance, mental disorder diagnosis, duration of mental disorder, and type of offense (p < 0.05). The benefit provided by timely and appropriate psychosocial interventions may have a key role in solving this problem for adolescents and improving their future as adults.

(Wiley, 2025) Simsek, Ferhat; Naci, Baha; Kilicoglu, Meltem Bozaci; Alkan, Zeynep; Topcuoglu, Osman Melih; Gormez, Aysegul; Okyar, Ali Fethi
Objective. Shoulder and neck dysfunctions resulting from spinal accessory nerve injury impair quality of life. This study aims to investigate the effects of manual therapy in combination with standard physiotherapy on the mechanical properties of muscle, neck and shoulder function, pain, and quality of life in head and neck cancer patients. Study Design. Prospective, randomized, controlled, double-blind clinical trial. Setting. Department of Otorhinolaryngology Head and Neck Surgery of a university hospital. Methods. A total of 26 participants were randomized into two groups. The control group (n = 11) received standard physiotherapy including therapeutic exercises, scar tissue massage, and education. The intervention group (n = 10) received manual therapy consisting of soft tissue, myofascial release, and mobilization techniques in combination with standard physiotherapy. Outcome measures were mechanical properties of muscle, neck and shoulder active range of motion, shoulder pain and disability, and quality of life. Results. Upper trapezius and sternocleidomastoid muscle stiffness increased significantly in the control group (P < .01), whereas a significant reduction was observed in the intervention group compared to the control group (P = .001). A reduction in muscle thickness was observed bilaterally in both groups (P < .01). Moreover, all participants showed improvements in neck and shoulder active range of motion, shoulder pain, and quality of life (P < .01). Conclusion. Manual therapy in addition to standard physiotherapy was more effective in improving neck and shoulder function, quality of life, and reducing muscle stiffness compared to standard physiotherapy alone. Therefore, clinicians should consider incorporating manual therapy into their treatment protocols to optimize patient outcomes.

Coach Candidates' and Coaches' Nutrition Knowledge Affects Dietary Recommendations Indirectly: Mediator Effects of Self-Efficacy
(Mdpi, 2025) Altinok, Oyku; Bas, Murat
Background/Objectives: The nutritional knowledge and behavior of athletes are considerably influenced by the dietary recommendations of their coaches, which, in turn, affect their health and performance. In the context of social cognitive theory, this study examines the impact of general and sports nutrition knowledge (GeSNK), nutrition self-efficacy (NSE), and nutrition counseling self-efficacy (NCSE) on the dietary recommendations (DRs) provided by coach candidates and coaches (CC&Cs). Additionally, it explores variations in GeSNK, NSE, and NCSE among CC&Cs based on their sports positions, genders, and types of sports. Methods: This study included 70 coach candidates and 102 coaches, with data collected via validated scales for GeSNK, NSE, and NCSE. Using the PROCESS macro, the serial multiple mediator model was applied, and group comparisons were conducted via the Mann-Whitney U test. Results: The results revealed that 36% of participants achieved adequate GeSNK scores, but only 6.4% abstained from providing DRs. Participants engaged in individual sports exhibited higher NSE and NCSE scores than those involved in team sports. Additionally, 22.7% of CC&Cs identified their former coaches as a primary source of nutrition information. The study findings revealed that GeSNK, NSE, and NCSE significantly influenced DRs, collectively accounting for 23% of the variance in DRs. The direct effect of NCSE on DRs was statistically significant, whereas the direct effects of GeSNK and NSE were not significant. GeSNK and NSE jointly explained only 41% of the variance in NCSE, suggesting that additional factors influencing NCSE and DRs remain unexplored. Conclusions: To address the issue of inadequate dietary recommendations stemming from insufficient information, it is crucial to identify and understand these additional factors affecting NCSE and DRs. Diversifying nutrition education programs to enhance the nutrition knowledge of CC&Cs is essential. Furthermore, fostering collaboration between CC&Cs and nutritionists can ensure that athletes receive accurate and comprehensive nutritional guidance.

Cochleogram-Based Speech Emotion Recognition With the Cascade of Asymmetric Resonators With Fast-Acting Compression Using Time-Distributed Convolutional Long Short-Term Memory and Support Vector Machines
(Mdpi, 2025) Parlak, Cevahir
Feature extraction is a crucial stage in speech emotion recognition applications, and filter banks with their related statistical functions are widely used for this purpose. Although Mel filters and MFCCs achieve outstanding results, they do not perfectly model the structure of the human ear, as they use a simplified mechanism to simulate the functioning of human cochlear structures. The Mel filters system is not a perfect representation of human hearing, but merely an engineering shortcut to suppress the pitch and low-frequency components, which have little use in traditional speech recognition applications. However, speech emotion recognition classification is heavily related to pitch and low-frequency component features. The newly tailored CARFAC 24 model is a sophisticated system for analyzing human speech and is designed to best simulate the functionalities of the human cochlea. In this study, we use the CARFAC 24 system for speech emotion recognition and compare it with state-of-the-art systems using speaker-independent studies conducted with Time-Distributed Convolutional LSTM networks and Support Vector Machines, with the use of the ASED and the NEMO emotional speech dataset. The results demonstrate that CARFAC 24 is a valuable alternative to Mel and MFCC features in speech emotion recognition applications.

(Wiley, 2022) Harmancı Seren, Arzu Kader; Zuriguel-Perez, Esperanza; Seren, Arzu Kader Harmanci; Hemşirelik Bölümü
Aims and objectives The study investigated clinical nurses' critical thinking levels in public hospitals and related factors. Background Since health care environments have become more complex, the critical thinking skills of clinical nurses are more important in daily problem-solving and decision-making processes. However, little research was conducted on this topic among clinical nurses. Methods It was a cross-sectional study at five public hospitals between December 2018 and January 2019. The study followed the STROBE guideline. Data were collected from 559 nurses by a survey consisted of a data form and the Turkish version of the Nursing Critical Thinking in Clinical Practice Questionnaire. Results Nurses' mean critical thinking scores were moderate level. Total critical thinking scores of the clinical nurses significantly differed according to education, hospital type, shift work, professional category and role. There was a significant effect on the total critical thinking scores of the clinical nurses according to variables. Conclusion This study found that critical thinking levels of nurses' working in clinical settings in public hospitals were moderate level. Hospital type, shift work, professional and educational level and role were significantly associated with clinical nurses' critical thinking levels. Relevance to clinical practice This study provides evidence related to the levels of critical thinking of clinical nurses working in public hospitals. Since the critical thinking scores of the manager nurses, daytime working nurses' and nurses with bachelor's and master's degree education are higher, hospital managers may benefit from the study to implement effective strategies to improve the competence of critical thinking levels of nurses.

(Elsevier Ireland Ltd, 2025) Yilmaz, Ozgur; Biliz, Yagmur; Ayan, Sumeyra; Cevik, Ozge; Karahasanoglu, Mufide; Cotuker, Reyhan; Kucukguzel, S. Guniz
In the present study, a range of novel thiosemicarbazides 4a-i and 1,2,4-triazoles 5a-i derived from ibuprofen, were synthesized. Structural elucidation of these synthesized compounds was performed utilizing a variety of spectroscopic methods, including FTIR, 1H NMR, 13C NMR and HR-MS. The synthesized compounds were tested for cytotoxicity in five different cancer cell lines (cervical cancer (HeLa), human breast cancer (MCF-7), human gastric adenocarcinoma (MKN-45), human metastatic prostate cancer (PC3) and human glioblastoma (U87)). The compounds were compared with healthy cells (NIH-3T3) and the most effective compounds were determined by means of the selectivity index. Thiosemicarbazides derived form ibuprofen 4i and 4d showed anticancer activity, while 1,2,4-triazoles derived form ibuprofen 5b, 5c, 5d, 5e, 5h, 5g showed anticancer activity in HeLa, MCF-7, MKN-45, PC3 and U87 cells. To test the stability of the protein-drug complexes all 18 compounds 4a-i and 5a-i were docked into the active site of the MetAP2 enzyme In general, computational inhibition constants values were correlated with the experimental values. The dynamic behavior of MetAP2-inhibitor complexes was analyzed using all atoms Molecular Dynamic (MD) simulations for 200 ns duration. MD revealed that the drugs bind in the active center of MetAP2 with stable RMSD and RMSF. In conclusion, in-silico results and in-vitro studies suggests that thiosemicarbazides and 1,2,4-triazoles derived from ibuprofen may be novel anticancer drug candidates for treating cervical, breast, prostate, gastric and glioblastoma. Compounds provided induction of apoptotic proteins in the cell by inhibiting MetAP2 enzyme. Furthermore, the potential antioxidant activities of the compounds were evaluated using the 2,2-Diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activity assay. Among the compounds tested, 4a, 4b, 4e, 4f, 4h, and 4i exhibited values closely resembling the DPPH activity of the standards.

The Dramatic Increase in Anti-Vaccine Discourses During the Covid-19 Pandemic: a Social Network Analysis of Twitter
(Taylor & Francis inc, 2022) Durmaz, Nihal; Hengirmen, Engin
Background/Aim The first case of COVID-19 in Turkey was officially recorded on March 11, 2020. Social media use increased worldwide, as well as in Turkey, during the pandemic, and conspiracy theories/fake news about medical complications of vaccines spread throughout the world. The aim of this study was to identify community interactions related to vaccines and to identify key influences/influencers before and after the pandemic using social network data from Twitter. Materials and methods Two datasets, including tweets about vaccinations before and after COVID-19 in Turkey, were collected. Social networks were created based on interactions (mentions) between Twitter users. Users and their influence were scored based on social network analysis and parameters that included in-degree and betweenness centrality. Results In the pre-COVID-19 network, media figures and authors who had anti-vaccine views were the most influential users. In the post-COVID-19 network, the Turkish minister of health, the was the most influential figure. The vaccine network was observed to be growing rapidly after COVID-19, and the physicians and authors who had opinions about mandatory vaccinations received a great deal of reaction. One-way communication between influencers and other users in the network was determined. Conclusions This study shows the effectiveness and usefulness of large social media data for understanding public opinion on public health and vaccination in Turkey. The current study was completed before the implementation of the COVID-19 vaccine in Turkey. We anticipated that social network analysis would help reduce the "infodemic" before administering the vaccine and would also help public health workers act more proactively in this regard.

The Earthquakes in Turkey and Their Effects on Nursing and Community Health
(Wiley, 2023) Harmancı Seren, Arzu Kader; Dikeç, Gül; Hemşirelik Bölümü
BackgroundSevere damage was experienced in 10 provinces in Turkey, and the north of Syria, with the earthquakes that hit Kahramanmaras at midnight and afternoon on February 6, 2023. AimThe authors aimed to give brief information to the international nursing community about the situation related to earthquakes in the aspects of nurses. ConclusionThese earthquakes caused traumatic processes in the affected regions. Many people, including nurses and other healthcare professionals, died or were injured. The results demonstrated that the required preparedness had not been applied. Nurses went to these areas voluntarily or on assignment and cared for individuals with injured. The universities in the country passed to distance education because of the shortage of safe places for victims. This situation also negatively influenced nursing education and clinical practice by interrupting in-person education one more time after the COVID-19 pandemic. Implications for nursing and nursing policySince the outcomes show a need for well-organized health and nursing care, policymakers may consider getting nurses' contributions to the disaster preparedness and management policy-making processes.

The Effect of an Educational Peer-Based Intervention Program on Sexual and Reproductive Health Behavior
(Wiley, 2024) Oğul, Zeynep; Sahin, Nevin Hotun; Ebelik Bölümü
IntroductionThe fact that adolescent people experience risky sexual behavior and have insufficient knowledge of sexual and reproductive health (SRH) indicates the need for SRH education. This study investigates the impact of peer-educated SRH programs on the knowledge and behaviors of adolescents.MethodThis study was conducted as a randomized controlled trial on 275 university students. The subjects were randomly assigned to the peer educators (n = 25), intervention (n = 125) and control (n = 125) groups using systematic random sampling. Peer educators provided face-to-face SRH education to the intervention group. The researcher provided the same education to the control group via the online conference method. SRH knowledge and behavior evaluated with scales before, after, and 3 and 6 months after the SRH education. The obtained data were analyzed using SPSS version 25 through statistical tests and analysis of covariance.ResultsThe female and male ratio of the participants was almost equal (49.4%, 50.6%). The mean age was found to be 20.42 +/- 1.14 years. The mean scores of the students in the intervention group increased from 21.20 +/- 0.14 to 35.20 +/- 0.07 for sexual health knowledge questionnaire (SHKQ), and from 130.56 +/- 0.55 to 147,90 +/- 0,25 for reproductive health scale (RHS) after the education. Compared with the control group, these increases in the mean scores of SHKQ and RHS were found to be statistically significant.ConclusionThe findings show the important role of the SRH peer education method on the effect of transferring knowledge about sexual behaviors. Health and education policy-makers are advised to implicate SRH peer education.

The Effect of Formative Assessment on Students' Clinical Knowledge, Skills and Self-Efficacy Levels
(Elsevier Sci Ltd, 2024) Kökkız, Rukiye; Inangil, Demet; Turkoglu, Ilayda; Tıbbi Hizmetler ve Teknikler Bölümü
Aim: This research aims to examine the effect of using formative assessment methods in clinical education on students' knowledge, skills and self-efficacy levels. Background: Formative assessment is used as a method designed to identify areas where students fall short and provide feedback for improvement. Formative assessment and feedback represent fundamental characteristics of quality teaching in higher education and play a decisive role in learning in nursing education. Although educators observe students performing practical tasks during clinical education, evaluation is not made by a structured control list. Therefore, just as nursing students are evaluated with "Skill Checklists" in the OSCE exam, there is a need to evaluate nursing skills during patient care in the clinical field. Design: The study was designed as a pre-test post-test randomized controlled experimental study. Method: Before the research, both groups filled out the self-efficacy form. The experimental group received formative assessment throughout the course. At the end of the semester, all students were given a skills test and asked to fill out the self-efficacy form again. Finally, a knowledge test was administered to the entire class. Results: The average knowledge score of the experimental group is higher than the control group. It was determined that there was a statistical difference of 16.54 points in the average skill scores between the groups. Posttests showed significant differences in skills such as breathing-cough exercise, basic glycemic measurement, subcutaneous injection and blood collection skills. Conclusion: It was determined that the formative assessment method increased nursing students' knowledge, skills and self-efficacy levels regarding basic nursing skills.

(Churchill Livingstone, 2020) Garipağaoğlu Denizhan, Muazzez; Garipagaoglu, Muazzez; Bicer, H. Selcen; Kurtulus, Duygu; Ozturk, Mustafa; Gunes, F. Esra; Beslenme ve Diyetetik Bölümü
Background & aims: Nutrition is one of the most important environmental factors affecting the formation of osteopenia. The purpose of this study was to investigate the effects of dietary changes on bone formation and bone resorption markers of postmenopausal women with vertebral osteopenia. Methods: In this study, 108 women with postmenopausal vertebral osteopenia were included. Patients were observed for a month to identify their regular nutritional status. Before intervention, blood and urine samples were taken from all patients. Then, 2-day food consumption records were taken and the patients were divided into 4 groups. Different types of diets (opposite of their regular diets) were prepared for these groups (1: control, 2: reduced-carbohydrate, 3: reduced-protein, 4: reduced-sodium) and followed for 3 months. At the end of follow-ups, blood and urine samples were taken again and changes in osteocalcin (OC) and N-terminal telopeptide (NTX) levels were examined. Results: According to biochemical analysis, there was a significant decrease (p < 0,001) in OC levels in reduced protein group and an increase (p > 0,05) in reduced carbohydrate group. When NTX levels were assessed, a significant decrease (p < 0.001) in the reduced carbohydrate group and a significant increase in the reduced protein group (p < 0.05) were found. Conclusion: Our findings show that reduced carbohydrate diet protected whereas, reduced protein diet negatively affected bone health. Osteopenic individuals were thought to be able to improve bone health and their quality of life by early dietary intervention.

(Springer/plenum Publishers, 2024) Pınar, Salih; Ozer, Dilara Fatos; Pinar, Salih; Antrenörlük Eğitimi Bölümü
The aim of this study was to examine the effect of motor intervention program (MIP) on autistic index, pre-academic skills, motor skills and social skills of children with Autism Spectrum Disorder (ASD). The research group consisted of a total of 34 participants between the ages of 3-6, 17 in the control group (CG) and 17 in the experimental group (EG). EG participated in the motor intervention program for 60 min a day, 2 days a week for 12 weeks. In the study, the Gilliam Autistic Disorder Rating Scale-2-Turkish Version (GARS-2 TV), Peabody Motor Development Scale-2 (PMDS-2), Pre-Academic Skills Evaluation Form (PASAF) and Social Skills Evaluation System Preschool Teacher Form (SSRS-PTF) were used. The increase in all subtests and total scores of PASAF and posttest scores obtained from PMDS-2 were found to be higher in favor of the experimental group (p < 0.05). The decrease in the stereotype and social interaction scores of GARS-2 TV and the change in the cooperation, self-control and externalization sub-dimensions of SSRS-PTF were found to be statistically significant in favor of the EG group (p < 0.05). In conclusion, it was found that MIP applied to autistic children was effective on the development of motor skills, academic skills and social skills and decreased the level of autistic index. This result shows that MIP is an effective practice that provides a favorable environment for autistic young children to develop multiple skills.

The Effects of Rational Emotive Behavior Therapy and Motivational Interviewing on Emotions, Automatic Thoughts, and Perceived Performance of Elite Female Volleyball Players
(Elsevier, 2023) Urfa, O.; Asci, F. H.
Objectives: The aim of this study was to examine the effect of Rational Emotive Behavior Therapy intervention alone (REBT-A) or with motivational interviewing (REBT + MI) on the emotions, automatic thoughts, and perceived performance of elite female volleyball players. Design: and method: Single-case, staggered multiple-baseline AB and ABC designs were adapted in the study. Five female volleyball players participated in the study, of which three players participated in the REBT-A and two players participated in the REBT + MI. The athletes were competing in the national volleyball league (Mage = 28, SD = 5.52). All participants were elite athletes with at least ten years of sports experience. Three scores (T1, T2, T3) were calculated for the athletes' perceived performance, emotion, and automatic thoughts. T1 was the baseline score calculated before the sessions. T2 was calculated after the first two sessions (the first three sessions for REBT + MI) and T3 was calculated after the last three sessions. In the data analysis, percentage changes, effect size, and visual analyzes were used in the T1, T2, and T3 scores. Results: REBT-A and REBT + MI interventions increased perceived performance, positive emotions, and positive automatic thoughts, and decreased negative emotions and negative automatic thoughts. REBT + MI was more advantageous than REBT-A in increasing positive emotion, positive automatic thought, and perceived performance. Conclusions: As a result, REBT alone or with motivational interviewing has a positive effect on perceived performance, emotions, and automatic thoughts, but REBT + MI has greater potential to increase positive constructs.

Gilaburu (viburnum Opulus L.) Fruit Extract Has Potential Therapeutic and Prophylactic Role in a Rat Model of Acetic Acid-Induced Oxidant Colonic Damage
(Elsevier Ireland Ltd, 2024) Şener, Göksel; Cam, Muhammet Emin; Yuksel, Meral; Akakin, Dilek; Taskin, Turgut; Emre, Gizem; Karakoyun, Berna; Eczacılık Meslek Bilimleri Bölümü
Ethnopharmacological relevance: Ulcerative colitis (UC) which has a global impact on the health care system with its recurrent and incompletely curable characteristics, affects the patients' quality of life. Gilaburu (GB; Viburnum opulus L.) is a fruit with rich polyphenol ingredient which is used ethnobotanically in T & uuml;rkiye for medicinal purposes (for example, to pass kidney stones, to treat stomach, heart, and liver diseases, hemorrhages, hypertension, ulcers, common cold, tuberculosis, rheumatic and menstrual pain, and diabetes). On the other hand, the effects of GB in the experimental UC model have not been studied.Aim of the study: This study aimed to explore the potential antioxidant and anti-inflammatory effects of GB fruit extract in improving acetic acid (AA)-induced UC.Materials and methods: Starting immediately after (AA + GB group) or 1 week before (GB + AA + GB group) the colitis induced by intrarectal AA (5%; v/v) administration, the rats orally received GB (100 mg/kg) once per day for 3 days. The control and AA groups were administered orally saline (1 ml), while the AA + SS group were administered sulfasalazine (SS; 100 mg/kg; orally) as a positive control once per day for 3 days. Distal colonic tissue specimens were obtained for the histological and biochemical [myeloperoxidase (MPO), malondialdehyde (MDA), glutathione (GSH), chemiluminescence (CL), caspase-3, 8-hydroxy-2(')-deoxyguanosine (8-OHdG), matrix metalloproteinase (MMP)-9, transforming growth factor (TGF)-beta(1), smad-3 and cytokine (tumor necrosis factor (TNF)-alpha, interleukin (IL)-1 beta, IL-6, IL-8, interferon (IFN)-gamma), measurements] evaluations on the 3(rd) day.Results: Elevated macroscopic and microscopic damage scores, high tissue wet weight values, increased tissue-associated MPO, MDA, CL, caspase-3, 8-OHdG, cytokines (TNF-alpha, IL-1 beta, IL-6, IL-8), MMP-9, TGF-beta(1), smad-3 levels, and decreased GSH values of the AA group were all reversed by GB treatments (AA + GB and GB + AA + GB groups) (p < 0.05-0.001). However, sulfasalazine treatment (AA + SS group) did not change the IL-8, 8-OHdG, MMP-9, and TGF-beta(1) measurements significantly.Conclusions: Gilaburu shows both anti-inflammatory and antioxidant effects against AA-induced colonic damage by suppressing neutrophil infiltration, regulating inflammatory mediators, inhibiting reactive species production, lipid peroxidation, and apoptosis, conserving endogenous antioxidant glutathione, and ameliorating oxidative DNA damage. Since the current ulcerative colitis drugs display limited benefits and adverse side effects, potential therapeutic and/or prophylactic role of gilaburu can be evaluated in ulcerative colitis.

in Silico Design, Synthesis and Antitubercular Activity of Novel 2-Acylhydrazono as Enoyl-Acyl Carrier Protein Reductase Inhibitors
(Taylor & Francis inc, 2024) Küçükgüzel, İlkay; Kumari, Jyothi; Tamhaev, Rasoul; Mourey, Lionel; Lherbet, Christian; Sriram, Dharmarajan; Kucukguzel, Ilkay; Eczacılık Meslek Bilimleri Bölümü
Mycobacteria regulate the synthesis of mycolic acid through the fatty acid synthase system type 1 (FAS I) and the fatty acid synthase system type-2 (FAS-II). Because mammalian cells exclusively utilize the FAS-I enzyme system for fatty acid production, targeting the FAS-II enzyme system could serve as a specific approach for developing selective antimycobacterial drugs. Enoyl-acyl carrier protein reductase enzyme (MtInhA), part of the FAS-II enzyme system, contains the NADH cofactor in its active site and reduces the intermediate. Molecular docking studies were performed on an in-house database (similar to 2200 compounds). For this study, five different crystal structures of MtInhA (PDB Code: 4TZK, 4BQP, 4D0S, 4BGE, 4BII) were used due to rotamer difference, mutation and the presence of cofactors. Molecular dynamics simulations (250 ns) were performed for the novel 2-acylhydrazono-5-arylmethylene-4-thiazolidinones derivatives selected by molecular docking studies. Twenty-three compounds selected by in silico methods were synthesized. Antitubercular activity and MtInhA enzyme inhibition studies were performed for compounds whose structures were elucidated by IR,H-1-NMR,C-13-NMR, HSQC, HMBC, MS and elemental analysis.

Inter-Rater Reliability in the Assessment of Consciousness in Patients Receiving Palliative Care in Intensive Care: a Prospective Cross Sectional Observational Study
(Wiley, 2024) Kuğu, Emre; Kavala, Arzu; Oz, Seda Degirmenci; Sezer, Esra; Kugu, Emre; Coskun, Zeynep; Tıbbi Hizmetler ve Teknikler Bölümü
BackgroundThe Glasgow Coma Scale (GCS) is one of the methods that has validity for evaluating the consciousness levels of patients in the literature and is accepted by health authorities.AimThe purpose of this study was to evaluate the inter-rater reliability of GCS in intensive care patients receiving palliative care.Study DesignA prospective cross sectional observational study. The study was conducted in a general intensive care unit with 20 beds with patients receiving palliative care. In the unit, 18 nurses worked in two shifts, day and night. Each patient's primary palliative care nurse and two additional researchers were given one minute to independently record the patient's GCS total and subscale scores. All observations were completed within 5 min as there could be significant changes in the patient's GCS score during observations.ResultsA total of 258 assessments were completed. For the GCS total scoring, a moderate agreement was found between palliative care nurses and the first researcher-observer (49.0%) and also between palliative care nurses and the second researcher-observer (47.7%). In addition, there was a substantial agreement between the first and second researchers (78.9%) and also between all observers (61.5%) (all p = .001).ConclusionsAlthough there was a near-perfect agreement between the two researcher-observers, we found only moderate agreement among all observers (palliative care nurses and two researcher-observers) in the evaluation of GCS total and subscale scores.Relevance to Clinical PracticeWe found that lack of knowledge and training on the standardized use of GCS is still a problem for palliative and intensive care units. Because of the diversity of patients requiring GCS assessment in palliative care units, refresher training programs and hands-on workshops on consciousness assessment should be organized regularly for more experienced nurses.

Monkeypox Post-Covid Knowledge, Worrying, and Vaccine Adoption in the Arabic General Population
(Mdpi, 2023) Swed, Sarya; Bohsas, Haidara; Alibrahim, Hidar; Rakab, Amine; Hafez, Wael; Sawaf, Bisher; Sah, Ranjit
Background: The outbreak of monkeypox was declared a global public health emergency by the World Health Organization on 23 July 2022. There have been 60,000 cases reported worldwide, most of which are in places where monkeypox has never been seen due to the travel of people who have the virus. This research aims to evaluate the general Arabic population in regard to the monkeypox disease, fears, and vaccine adoption after the WHO proclaimed a monkeypox epidemic and to compare these attitudes to those of the COVID-19 pandemic. Methods: This cross-sectional study was performed in some Arabic countries (Syria, Egypt, Qatar, Yemen, Jordan, Sudan, Algeria, and Iraq) between 18 August and 7 September 2022. The inclusion criteria were the general public residing in Arabic nations and being older than 18. This questionnaire has 32 questions separated into three sections: sociodemographic variables, prior COVID-19 exposure, and COVID-19 vaccination history. The second portion assesses the knowledge and anxieties about monkeypox, while the third section includes the generalized anxiety disorder (GAD7) scale. Logistic regression analyses were performed to compute the adjusted odds ratios (aOR) and their confidence intervals (95%CI) using STATA (version 17.0). Results: A total of 3665 respondents from 17 Arabic countries were involved in this study. Almost two-thirds (n = 2427, 66.2%) of the participants expressed more worry about COVID-19 than monkeypox diseases. Regarding the major cause for concern about monkeypox, 39.5% of participants attributed their anxiety to the fear that they or a member of their family may contract the illness, while 38.4% were concerned about monkeypox becoming another worldwide pandemic. According to the GAD 7 score, 71.7% of the respondents showed very low anxiety toward monkeypox and 43.8% of the participants scored poor levels of knowledge about monkeypox disease. Participants with previous COVID-19 infection showed a 1.206 times greater acceptance to receive the monkeypox vaccine than those with no previous infection. A 3.097 times higher concern for monkeypox than COVID-19 was shown by the participants who perceived monkeypox as dangerous and virulent than those who did not. Participants who have a chronic disease (aOR: 1.32; 95%CI: 1.09-1.60); participants worried about monkeypox (aOR: 1.21; 95%CI: 1.04-1.40), and perceived monkeypox as a dangerous and virulent disease (aOR: 2.25; 95%CI: 1.92-2.65); and excellent knowledge level (aOR: 2.28; 95%CI: 1.79-2.90) have emerged as significant predictors. Conclusions: Our study reported that three-fourths of the participants were more concerned about COVID-19 than monkeypox disease. In addition, most of the participants have inadequate levels of knowledge regarding monkeypox disease. Hence, immediate action should be taken to address this problem. Consequently, learning about monkeypox and spreading information about its prevention is crucial.

A Multinational Cross-Sectional Study on the Awareness and Concerns of Healthcare Providers Toward Monkeypox and the Promotion of the Monkeypox Vaccination
(Frontiers Media Sa, 2023) Swed, Sarya; Alibrahim, Hidar; Bohsas, Haidara; Jawish, Nagham; Rais, Mohammed Amir; Nasif, Mohamad Nour; Data Collection Grp
BackgroundThe aim of this study was to explore potential healthcare workers' (HCWs) concerns about the monkeypox virus in order to create practical solutions to manage this disease. MethodsOnline cross-sectional research was conducted in 11 Arabic countries (Egypt, Saudi Arabia, Yemen, Syria, Libya, Algeria, Tunisia, Iraq, Palestine, Jordan, and Sudan) from 2 August 2022 to 28 December 2022. ResultsApproximately 82% of respondents felt the need to acquire further information. The acceptability of the vaccine against monkeypox has been indicated by more than half of the participants (54.5%). Furthermore, we state that 45% of the participants are knowledgeable about the monkeypox virus, and 53.1% of the participants have never been affected with COVID-19 before are more worried about COVID-19 than about monkeypox. Participants diagnosed with COVID-19 were 0.63 times less likely to worry about monkeypox than those who were not diagnosed with COVID-19. A greater willingness to get the monkeypox vaccination was seen among the age group 21-30 years (42.4%) compared to the other age groups. ConclusionMost healthcare professionals have a moderate knowledge of the monkeypox virus. Furthermore, they demonstrated a low willingness to get the vaccination against the monkeypox virus.

A Novel Petox-Based Nanogel Targeting Prostate Cancer Cells for Drug Delivery
(Wiley-v C H verlag Gmbh, 2024) Gulyuz, Sevgi; Sessevmez, Melike; Ukuser, Gokcen; Khalily, Melek Parlak; Tiryaki, Selen; Sipahioglu, Tarik; Yilmaz, Ozgur
This study focuses on creating a specialized nanogel for targeted drug delivery in cancer treatment, specifically targeting prostate cancer. This nanogel (referred to as SGK 636/Peptide 563/PEtOx nanogel) is created using hydrophilic poly(2-ethyl-2-oxazoline) (PEtOx) through a combination of living/cationic ring-opening polymerization (CROP) and alkyne-azide cycloaddition (CuAAC) "click" chemical reactions. A fluorescent probe (BODIPY) is also conjugated with the nanogel to monitor drug delivery. The characterizations through 1H-NMR, and FT-IR, SEM, TEM, and DLS confirm the successful production of uniform, and spherical nanogels with controllable sizes (100 to 296 nm) and stability in physiological conditions. The biocompatibility of nanogels is evaluated using MTT cytotoxicity assays, revealing dose-dependent cytotoxicity. Drug-loaded nanogels exhibited significantly higher cytotoxicity against cancer cells in vitro compared to drug-free nanogels. Targeting efficiency is examined using both peptide-conjugated and peptide-free nanogels, with the intracellular uptake of peptide 563-conjugated nanogels by tumor cells being 60-fold higher than that of nanogels without the peptide. The findings suggest that the prepared nanogel holds great potential for various drug delivery applications due to its ease of synthesis, tunable functionality, non-toxicity, and enhanced intracellular uptake in the tumor region. This study emphisizes an innovative PEtOx-based nanogel tailored for targeted drug delivery in prostate cancer. Developed using click chemistry, a valuable technique for chemical synthesis, it exhibits consistent nanogel formation with customizable sizes. In vitro, drug-loaded nanogel exhibits potent cytotoxicity against cancer cells. Notably, peptide-conjugated nanogels significantly boost tumor cell uptake, showcasing promising promising potential for effective cancer drug delivey.image
