Coexistence of Ophthalmic Shingles and COVID-19 in a Patient Who Applied with Encephalitis Clinic

Varicella zoster virus (VZV) is a member of the herpes virus family and is the causative agent of chickenpox and shingles. While chickenpox, which is the primary infection, is mostly seen in childhood, shingles is located latently in the dorsal root sensory ganglia and cranial nerve ganglia, causing recurrent attacks in adulthood. Shingles may rarely present with neurological complications such as encephalitis. Many diseases are seen in the coexistence of Coronavirus disease-2019 (COVID-19) due to the pandemic. In this case report, it was aimed to draw attention to the ophthalmic varicella zoster virus infection with a different clinical onset accompanied by COVID-19 who presented with the clinic of encephalitis.

Poor Risk Factors Affecting Cancer Patients Infected with Covid-19: A Retrospective Comparative Study from a Pandemic Hospital

OBJECTIVE It is known that cancer patients are more prone to infections than the general population. We aimed to describe the risk factors affecting the survival of cancer patients infected with COVID-19 and clinical findings compared with a large COVID-19 patient population without cancer diagnosis. METHODS The clinical data of 61 cancer and 558 non-patients with COVID-19 infection who applied to the emergency room were compared retrospectively. Risk factors affecting overall survival in cancer patients were analyzed. RESULTS Gender and mean age were comparable in both groups. In the entire cohort, cancer diagnosis was found to be an independent poor prognostic factor (hazard ratio [HR] = 3.09, p<0.001) among other comor-bidities. In univariate analysis;lung cancer, activated partial thromboplastin time >32 seconds, INR >1.1, N-terminal-pro-B-type natriuretic peptide (NT-proBNP) >400 pg/ml, C-reactive protein >100 mg/L, and procalcitonin >0.23 ng/mL were determined as prognostic risk factors. Lung cancer (HR=5.277, p=0.012) and NT-proBNP >400 pg/ml (HR=0.139, p=0.021) were determined as independent prognostic risk factors in multivariate analysis. CONCLUSION Cancer patients with COVID-19 infection have poor survival outcomes. Lung cancer diagnosis and elevated NT-proBNP levels were identified as the most crucial prognostic risk factors in cancer patients infected with COVID-19.Copyright © 2023, Turkish Society for Radiation Oncology.

The effect of smoking habit on morbidity and mortality in COVID-19 intensive care patients

Objective: In smokers, COVID-19 may have a more severe course due to impaired mucociliary activity, increased permeability, and inflammation of the airway epithelium. However, data on the impact of smoking in patients with COVID-19 pneumonia are conflicting. The study aimed to evaluate the effects of smoking on laboratory parameters, intensive care unit (ICU) length of stay, length of hospital stay, and mortality in COVID-19 patients hospitalized in the intensive careunit. Method(s): Medical records of 576 patients who were followed up in the ICU for COVID-19 between January and September 2021 were analyzed retrospectively. Demographic data, comorbidities, laboratory parameters (hemoglobin, white blood cell (WBC), lymphocyte, neutrophil, thrombocyte, AST, ALT, CRP, D-dimer, ferritin, BNP, albumin), ICU and hospital stay of the patients were recorded. The patients were divided into 2 groups according to whether they smoked or not. Result(s): The data of 576 patients were evaluated in the study. The mean age of the patients was 69 14.8 years, and 53.8% were male. The smoking rate was 30%, and the smoking rate in men was 76.9%. The intensive care unit admission age of smokers was lower than non-smokers (p=0.01). The presence of coronary artery disease (CAD), chronic obstructive pulmonary disease (COPD), and malignancy was significantly higher in smokers. Among the laboratory parameters, white blood cell count (WBC) and neutrophil were higher in smokers (p=0.01). There was no relationship between ICU length of stay, length of hospital stay, and mortality in smokers (p=0.769, p=0.699, p=0.852, respectively). Conclusion(s): We did not find any significant association between smoking and COVID-19 mortality. We recommend clinicians to monitor WBC and neutrophil count closely as markers of possible progression to critical illness in patients hospitalized in the ICU due to smoking COVID-19.

Borderline, Narcissistic, Obsessive-Compulsive and Schizoid Personality Disorder Beliefs and Their Effects on Anxiety and Depression Levels in Inpatients with Covid-19

Objective: Mental-health problems among coronavirus disease 2019 (COVID-19) inpatients is an underinvestigated issue. The study reported herein was conducted to assess obsessive-compulsive, borderline, schizoid and narcissistic personality disorder beliefs and the influence of these dysfunctional beliefs on the anxiety and depression levels of COVID-19 inpatients.Methods: A total of 75 COVID-19 inpatients were recruited for the study. Their anxiety and depression levels were evaluated using Hospital Anxiety and Depression Scale, and the aforementioned personality disorder beliefs were evaluated using Personality Belief Questionnaire -Short Form.Results: According to the cut-off values, 9.3% (n = 7) of the inpatients were considered having anxiety and 34.7% (n = 26) were considered having depression. The mean scores for obsessive-compulsive, schizoid, borderline and narcissistic personality disorder beliefs were 15.1 +/- 6.2, 12.9 +/- 6.0, 10.0 +/- 5.5 and 9.4 +/- 5.6, respectively. The anxiety levels of the female inpatients were significantly higher than those of the male inpatients (z = 2.152;p = 0.031). The inpatients' borderline personality disorder belief scores were significantly correlated with their anxiety levels (r = 0.390;p = 0.001).Conclusion: The study participants' obsessive-compulsive personality disorder beliefs were higher than their other aforementioned personality disorder beliefs. Female gender and borderline personality disorder beliefs were found to be related with anxiety level. The influence of these factors should be considered in the evaluation of COVID-19 inpatients in daily clinical practice.

Knowledge, Attitude and Anxiety Levels about COVID-19 among Healthcare Workers at Ankara City Hospital, Türkiye

Introduction: We aimed to assess the present knowledge, attitude and anxiety levels of coronavirus disease 2019 (COVID-19) among healthcare workers at Ankara City Hospital. Materials and Methods: The study was implemented in the form of an online survey, based on voluntary participation and conducted on healthcare workers at the Ministry of Health Ankara City Hospital by using convenience sampling and snowball method between 30 May-2 July 2020. There were 28 questions on knowledge and 8 questions on attitude. The Beck Anxiety Inventory (BAI) was used to measure the anxiety level of the participants. The results were analyzed using the SPSS program. Results: Of the participants, 75% were females, 61.25% were nurses/midwives, and mean age was 34.5 ± 10.1 years. A significant portion of the participants (84.50%) had a moderate or adequate level of knowledge. The highest knowledge score in terms of their professions are doctors, followed by nurses/midwives. The most used resource (71.25%) by our participants was the Ministry of Health’s web page, posters and brochures. The knowledge adequacy of those who have a case algorithm is 1.8 times. Of the participants, 61.0 % demonstrated a positive attitude. 25.25% were gauged to have severe and moderate anxiety. Of the participants, 42.39% stated that anxiety causing reason was the future of their family in case of death in our study. The anxiety score of the female participants was higher than that of the men, young people were higher than the other age groups. There was no significant correlation between the level of knowledge and attitude;whereas a negative, weak correlation was identified between the level of knowledge and anxiety, and between attitude and anxiety. Conclusion: Although the knowledge level of the participants was found to be adequate, in-service training on infection control measures, especially on the use of personal protective equipment should be continued using official information, such as algorithms are designed and other sources by the Ministry of Health. Health workers, especially women and young people, should be monitored psychologically, treated and social support for them should be increased during the pandemic. Increasing knowledge and positive attitudes may be contribute to decrease anxiety scores.

Pediatric Appendicitis Management During the COVID-19 Pandemic: What Has Changed?

Introduction: The most common surgical emergency in the paediatric group during the coronavirus disease-2019 (COVID-19) pandemic is appendicitis, as it was before. This study aimed to evaluate clinical differences of paediatric appendicitis cases and changes in the management strategy between the pandemic and non-pandemic period. Methods: Cases during the non-pandemic period (March-July 2019) and pandemic period (March-July 2020) were analysed. Demographic data, duration of symptoms, physical examination, laboratory and radiological findings, paediatric appendicitis score (PAS), operative techniques, medical treatment, complications and hospital stay were evaluated retrospectively. Results: This study enrolled 70 patients during the non-pandemic period and 48 patients during the pandemic period. Duration of symptoms was significantly prolonged (p<0.001) and PAS was significantly increased during the pandemic period (p=0.001). Abdominopelvic ultrasonography detected abscess formation in one (1.4%) patient and 10 (20.8%) patients during the non-pandemic period and pandemic period, respectively. Complicated appendicitis was significantly higher (p=0.025) and the hospital stay were significantly longer during the pandemic period (p=0.017). Conclusion: During the COVID-19 pandemic, fewer patients presented to the paediatric emergency department with suspected appendicitis. Complicated appendicitis cases and hospital stay increased during the same period. The COVID-19 pandemic caused some changes in our approach to paediatric appendicitis cases such as the effective use of personal protective equipment, PAS scoring system and abdominopelvic ultrasonography. © 2021 by Society of Pediatric Emergency and Intensive Care Medicine.

COULD COVID-19 TRIGGER TYPE 1 DIABETES? PRESENTATION OF COVID-19 CASE PRESENTED WITH DIABETIC KETOACIDOSIS

COVID-19 is a viral disease that is recognized now as a pandemic by the World Health Organization. It is known that some viral infections may trigger autoimmune diseases. It has been revealed that COVID-19 may also lead to the pathogenesis of some autoimmune diseases, including Type 1 DM (T1DM) and autoimmune thyroid diseases. Here, we aimed to present a young female patient with COVID-19, who we followed up in our clinic, who presented with diabetic ketoacidosis (DKA), and developed Hashimoto’s disease during the treatment process. In order to emphasize that COVID-19 may trigger the emergence of T1DM, that it may mask nonspecific DKA symptoms like nausea and vomiting, that it may cause delay in diagnosis of DKA, and also to emphasize the importance of evaluating other autoimmune diseases accompanying COVID-19, we found it appropriate to present this case.

Label-free and reagent-less electrochemical detection of nucleocapsid protein of SARS-CoV-2: an ultrasensitive and disposable biosensor

A novel selective and ultrasensitive sandwich biosensor was developed for the detection of nucleocapsid biomarkers of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The biosensor fabrication strategy was composed of a combination of gold nanoparticles (AuNPs) electrodeposition and an aldehyde substituted thiophene monomer (3-Thi-Ald) electropolymerization. In this study, an effective surface design was achieved during biosensor fabrication by covalent immobilization of biorecognition elements. The Pthi-Ald polymer not only formed a surface immobilization matrix, but also supported the electrode surface conductivity with its conductive property. The immobilized antibodies on Pthi-Ald polymer could selectively capture nucleocapsid antigen via the specific immunoreaction that resulted in a blockage of the electron transfer through the working electrode because of the resistance of nucleocapsid protein. Electrochemical impedance spectroscopy (EIS), cyclic voltammetry (CV), and scanning electron microscopy (SEM) techniques were utilized to confirm the step-by-step fabrication procedure of the immunosensor. The developed immunosensor showed good selectivity, high storage stability, acceptable repeatability, and a good reproducibility for nucleocapsid detection. The AuNPs-Pthi-Ald polymer modified biosensor illustrated a good linear dynamic detection range between 0.0015 pg mL(-1) and 150 pg mL(-1) nucleocapsid concentration with a low detection limit of 0.48 fg mL(-1). Moreover, the immunosensor had excellent selectivity, stability, and performance in the analysis of artificial nasal secretion samples. This strategy provided a new aspect for the early screening of SARS-CoV-2 infection.

THE EFFECT OF THE PANDEMIC ON THE CONSUMPTION OF ANIMAL PRODUCTS: THE CASE OF KAFKAS UNIVERSITY OF TURKEY

The COVID-19 pandemic has brought about some changes in consumption preferences and nutritional habits as well as lifestyles of individuals, such as education, working system, and social relationships, especially due to having to stay at home. In this study, the change in animal food consumption dispositions of students who had to stay at home during the pandemic and received online education was examined compared to the pre-pandemic period. In the study, since face-to-face teaching-learning activities were suspended, an online questionnaire was used to collect the study data from a total of 380 students registered at Kafkas University. The average monthly income of the participants and the share they allocated to the total food and animal products expenditures in the budget were determined as 539.64±21.00$, 132.73±5.08$, and 62.18±2.67$, respectively. Although the annual chicken meat consumption amount did not change according to the income levels of the students, it was determined that the consumption of animal products, such as beef, mutton-lamb, milk-yogurt, cheese, and eggs increased as the income level increased. During the pandemic period, the food consumption of 55.3% of the participants and the animal products consumption of 35.8% increased. On the other hand, it was determined that the consumption of food and animal products increased as the income level increased during the pandemic compared to the pre-pandemic period. During the pandemic period, it was determined that red meat and salami-sausages consumption of 31.8% of the students decreased by 37.90% and 42.15%, respectively, but that the chicken meat consumption of 31.3% of the students and milk and dairy products consumption of 37.9% increased by 31.02% and 39.17%, respectively. As a result, it was determined that there were significant changes in the nutritional habits of the students during the COVID-19 pandemic, and it was determined that there were significant increases in the consumption of animal products other than red meat. The primary reason why red meat consumption did not increase is thought to be due to the high price of the product compared to consumers’ income levels © 2022, Online Journal of Animal and Feed Research.

In COVID-19 suspicion without severe manifestations, chest ct sensitivity is not sufficient for triage: a single-centre experience

Objectives: In Coronavirus diseases-2019 (COVID-19), chest computed tomography's (CT) benefits are controversial in the subgroup of asymptomatic and mild-to-moderate symptomatic individuals. Since most patients are in this subgroup, for triage, it is necessary to choose the diagnostic tool with the highest diagnostic performance and the least risk. We aimed to evaluate chest CT findings and the initial chest CT's sensitivity in individuals suspected of COVID-19 with no severe disease manifestations. Materials and Methods: We conducted a retrospective study. Symptomatic individuals who had mild-to-moderate clinical manifestations and asymptomatic individuals who had close contact with confirmed COVID-19 positive patient were eligible. Presenting severe clinical manifestations was excluded. Reverse transcriptase-polymerase chain reaction (RT-PCR) and chest CT were performed on admission day. Consecutive nasopharyngeal and oropharyngeal swab sampling, tested by RT-PCR, were accepted as the reference standard for definitive diagnosis of COVID-19.

Public interest in musculoskeletal symptoms and disorders during the covid-19 pandemic: Google trends analysis in turkey: Cross-sectional study

Objective: To investigate the public interest in symptoms of musculoskeletal system and disorders during coronavirus disease-2019 (COVID-19) pandemic by using the Google data. Material and Methods: We set a wide range of search queries including general symptoms of musculoskeletal system and symptoms and disorders of spine, neck, low back, shoulder, elbow, wrist, hand, hip, knee, ankle and foot. On Google Trends, we searched for 108 search queries, within Turkey, in “All Categories’for two different time intervals as early and later period (15 March-4 July ve 5 July-26 December 2020) comparing the similar time intervals of previous four years (2016-2019). Results: When we compare the queries in COVID-19 pandemic with the previous 4 years;we found that;12 of 108 queries (joint, arm, leg, neck, waist, shoulder, elbow, hand, finger, foot, heel pain and carpal tunnel) showed a significantly increase, 37 queries decrease and no difference was observed in 59 queries in early period. In later period, 17 of 108 queries showed a significantly increase, 27 queries decrease and no difference was observed in 64 queries. Conclusion: In Turkey, during the early period of the COVID-19 pandemic, it is observed that;Google search volume about musculoskeletal system symptoms and disorders decreased while search volume about pain increased. During the later period, search volume increased to the same level as in previous years additionally search volume about pain increased again. These results may help to see the needs of the public, presenting these needs to specialists and managers dealing with musculoskeletal system.

The knowledge and opinions of the faculty of medicine students about vaccination, immunization, vaccine hesitation and COVID-19 vaccine in Turkey

Objective: Vaccination is one of the most effective public health practices in preventing and controlling infectious diseases. Vaccine instability is a rapidly increasing risk for our country as well as for the whole world. There is a strong relationship between physicians' attitudes towards vaccines and their recommendations for vaccines to their patients. Determining the acceptance of the vaccine, which is at the forefront during the fight against the COVID-19 pandemic by physicians who are role models for the society with their attitudes and behaviors, will guide the vaccination studies to be carried out. In this study, it was aimed to examine the knowledge and thoughts of medical faculty students in our country about vaccination, immunization, vaccine instability and COVID-19 vaccine. Methods: In this descriptive study, between December 2020-January 2021, it is aimed to reach the medical students members of “33 Student Societies” (FMO, Faculty Member Organization) affiliated to the European Medical Students' Association (EMSA) in Turkey and students studying at medical faculties in our country through members. The data were collected through an online questionnaire. 1015 students participated in the study. Results: In the study 64.7% of the participants are women. The average age is 21.2 ± 2.5 years. 86.4% of the participants state that vaccine instability in our country has increased. It is thought that the negative statements about vaccines in the media are the most important reason for this situation. It is stated that it is important to educate parents in order to prevent / reduce vaccine instability. When 53.4% of the participants are informed that the COVID-19 vaccine is suitable for use by the Ministry of Health, they indicated “I will not do it immediately, I wait.” as the answer. Conclusion: It is thought that the number of vaccine instabilities in our country is increasing and this will cause an increase in epidemics. It is important to increase the knowledge and awareness of medical faculty students, who are role models for the society, about vaccines, immunization and vaccine hesitation from the beginning of the faculty. © 2021.

Quantitative Analysis of the Olfactory System in COVID-19: An MR Imaging Study.

BACKGROUND AND PURPOSE: Anosmia or hyposmia, often accompanied by changes in taste, is recognized as a common symptom that can assist in the diagnosis of coronavirus disease 2019 (COVID-19). The pathogenesis of olfactory dysfunction in COVID-19 is not yet fully understood. MR imaging represents a useful anatomic imaging method for the evaluation of olfactory dysfunction associated with varying etiologies, including viral infection, trauma, and neurodegenerative processes. This case-control study was conducted to compare quantitative measurements of olfactory anatomic structures between patients diagnosed with COVID-19 associated with persistent olfactory dysfunction and healthy controls. MATERIALS AND METHODS: This study has a retrospective design. Cranial MR imaging was performed on all participants in both the patient and control groups. The bilateral olfactory bulb volume, olfactory tract length, and olfactory sulcus depth were measured in all patients. RESULTS: A total of 116 people aged 18-60 years, including 36 patients diagnosed with COVID-19 and 80 controls, were included in the study. All measured values were compared between the patient and control groups. The right, left, and total olfactory bulb volume values were significantly lower in the patient group than in the control group. The patient group also had significantly lower right and left olfactory sulcus depth and olfactory tract length values compared with those in the control group. CONCLUSIONS: MR imaging findings can be used to demonstrate olfactory injury in patients with COVID-19. The olfactory pathway may represent an alternative route for virus entry into the central nervous system.

Extraordinary days, unusual circumstances: psychosocial effects of working with COVID-19 patients on healthcare professionals

Objectives: We asked healthcare professionals (HCPs) to describe the psychosocial effects the COVID-19 pandemic has had on them. We also aimed to raise awareness about the possible problems may have been encountered by the HCPs during the pandemic. Methodology: This qualitative study was conducted through semi-structured interviews with open-ended questions. A phenomenological approach used to collect data. Purposive and snowball sampling methods were used to recruit participants. We interviewed twelve HCP s. Topics included their first experience with a COVID-19 case, changes in the work environment, working with personal protective equipment (PPE), changes in private life, and the challenges encountered. Data gathering and data analysis were carried out concurrently. We used the classical content analysis method for data analysis. Results: Four main categories emerged from the content analysis. The first was “Responsibility”. Healthcare professionals felt responsible towards both the patients and healthy people and some experiences made them feel helpless. They expressed a wide range of feelings about their professions. The second category was “Fatigue”. Participants explained that they experienced intense fear initially and were very overwhelmed. All participants thought that people were insensitive to follow measurements. The third category was “Relief”. Before the outbreak reached Turkey, medical staff could not predict what was coming. Over time they got used to this new situation, and normalize their lives. The fourth category was “Experience”. Participants told about what they learned during the pandemic and made some suggestions. Conclusion: Throughout the COVID-19 pandemic, some experiences can be demotivating and disappointing for healthcare professionals. Managers and supervisors should listen to their requests, and hearing positive feedback from authorities may increase their motivation. All kinds of psychosocial support should be provided for healthcare workers, and their mental well-being should be cared as well as their physical health. © 2021 Faculty of Anaesthesia, Pain and Intensive Care, AFMS.

The nexus between team culture, innovative work behaviour and tacit knowledge sharing: Theory and evidence

Tacit knowledge sharing is an essential intellectual capital for frontline employees in hotel enterprises. While the relationship of knowledge sharing with team culture (TC) and innovative work behavior (IWB) was investigated in the extant literature, little is known about the extent to which tacit knowledge sharing affects TC and IWB. In this regard, the purpose of this study is to investigate the role of tacit knowledge sharing in the relationship between TC and IWB. For this purpose, data were gathered from 360 department managers of Turkish 4–5 star hotels. The results were analyzed utilizing Smart PLS 3 using bootstrapping to determine the level of significance of the relationships between tacit knowledge sharing, TC and IWB. The results show statistically significant relationships between tacit knowledge sharing, TC and IWB. Moreover, tacit knowledge sharing has a mediating role in the relationship between team culture and innovative work behavior. © 2021 by the authors. Licensee MDPI, Basel, Switzerland.
