ABSTRACT
Instagram is a social media platform that allows users to share content such as photos and videos. Fake and bot account problems constitute a significant obstacle to social networking. Since fake and bot accounts have purposes such as increasing the number of followers, creating a perception by using misinformation, deceiving people, detecting these fake and bot accounts plays an essential role in creating a secure social network. Fake account detection is beneficial to keeping people safe from misinformation and malicious profiles on Instagram, ensuring customers' safe accounts, and preventing fraud. From this point, we aim to classify Instagram user profiles into fake, bot, and real accounts with classification algorithms. Additionally, we present a publicly available dataset for the fake, bot, and real accounts detection on Instagram. For data collection, real accounts were determined from our circle of friends, fake accounts were accessed by manual scanning from Instagram, and bot accounts were accessed by purchasing from bot account websites and mobile applications. These accounts' features were collected via web scraping. We use the seven classifiers to train classification models in fake, bot, and real profile detection. Our results show that the Random Forest gives the highest prediction accuracy with 90.2%.
ABSTRACT
BACKGROUND: This study aimed to investigate pregnancy frequency and evaluate the factors affecting live births in hemodialysis (HD) patients. METHODS: Female HD patients whose pregnancy was retrospectively reported between January 1, 2014, and December 31, 2019. The duration of HD, primary disease, and the information on whether the pregnancy resulted in abortion, stillbirth, or live birth, whether the HD duration was prolonged after diagnosing the pregnancy and whether it accompanied preeclampsia were recorded. RESULTS: In this study, we reached 9038 HD female patients' data in the study. A total of 235 pregnancies were detected in 145 patients. The mean age was 35.42 (35 ± 7.4) years. The mean age at first gestation was 30.8 ± 6.5 years. The average birth week was 32 (28 -36) weeks. A total of 53.8% (no = 78) of the patients had live birth, 51.7% (no = 70) had at least one abortion in the first 20 weeks, and 13.1% (no = 19) had at least one stillbirth after 20 weeks. The rate of patients' increased numbers of dialysis sessions during pregnancy was 71.7%. The abortion rate was 22.4% in those with increased HD sessions, whereas 79.3% in those not increased HD sessions (p < 0.001). Live birth frequency was 67.2% in the increased HD sessions group and 3.4% in those who did not differ in HD sessions (p < 0.001). DISCUSSION: For the first time, we reported pregnancy outcomes in HD female patients, covering all regions of Turkey. It has been observed that;increasing the number of HD sessions in dialysis patients will decrease fetal and maternal complications and increase live birth rates.
ABSTRACT
Objectives: We aimed to reveal the skin, mucous membrane, hair and nail findings of children who meet the multisystem inflammatory syndrome in children (MIS-C) criteria. Method: A prospective case series consisting of 43 children who applied to Karadeniz Technical University Faculty of Medicine Farabi Hospital between January 2020 and January 2022 and met the criteria for MIS-C according to the diagnostic criteria of the Centers for Disease Control and Prevention was conducted. Results: Of 43 patients diagnosed with MIS-C, 18 (%41,9) were female and 25 (%58,1) were male. The mean age of the patients is 7.63, the age range is between 7 months and 15 years. The results of polymerase chain reaction tests for SARS-CoV-2 were positive for 4 (%9,3) patients, and the results of SARS-CoV-2 immunoglobulin G tests were positive for 39 (%90,7) patients. No mucocutaneous involvement was observed in 3 (%6,9) of the patients. Nonpurulent conjunctivitis was observed in 25 (%58,1) patients, and periorbital edema was observed in 4 (%9,3) patients. 4 (%9,3) patients had symmetrical edema of the hands and feet, and 2 (%4,6) patients had periungual desquamation. While no oral mucosal findings were observed in 15 (%34,9) patients;12 (%27,9) patients had fissured lips, 10 (% 23,3) had cheilitis, 8 (%18,6) had diffuse hyperemia of the oral mucosa, 6 (%13,9) had strawberry tongue, and 3 (%6,9) had herpes labialis. 21 (%48,8) of the patients had urticarial, 12 (%27,9) of them maculopapular, 5 (%11,6) patients livedoid and 1 (%2,3) patient had a skin rash compatible with pseudopernio. No hair or nail changes were observed in the patients while they were hospitalized. Discussion: In this case series of hospitalized children with definitive MIS-C during the COVID-19 pandemic, a wide spectrum of mucocutaneous findings was identified.
ABSTRACT
BACKGROUND AND AIMS: There is not enough data on the post-COVID-19 (coronavirus disease 2019) period for peritoneal dialysis (PD) patients affected from COVID-19. We aimed to compare the clinical and laboratory data retrospectively obtained in the follow-up of PD patients after COVID-19 with a control PD group. METHOD: This study, supported by the Turkish Society of Nephrology, is a national multicenter retrospectively case-control study involving adult PD patients with confirmed COVID-19, using data collected from 21 April 2021 to 11 June 2021. A control PD group was also formed from each PD unit, from patients with similar characteristics but who did not have COVID-19. Patients in the active period of COVID-19 were not included. Data at the end of the first month and within the first 90 days, as well as other outcomes, including mortality, were investigated. RESULTS: A total of 223 patients (COVID-19 group: 113, control group: 110) from 28 centers were included. The duration of PD in both groups was similar [median (IQR):3.0 (1.88-6.0) years and 3.0 (2.0-5.6)], but the patient age of the COVID-19 group was lower than the control group [50 (IQR:40-57) years and 56 (IQR:46-64) years, P < 0.001]. PD characteristics and baseline laboratory data were similar in both groups, except serum albumin and hemoglobin levels on Day 28, which were significantly lower in the COVID-19 group. In the COVID-19 group, respiratory symptoms, rehospitalization, lower respiratory tract infection, change in PD modality, UF failure and hypervolemia were significantly higher on the 28th day. There was no significant difference in laboratory parameters at Day 90. Only one (0.9%) patient in the COVID-19 group died within 90 days. There was no death in the control group. Respiratory symptoms, malnutrition and hypervolemia were significantly higher at Day 90 in the COVID-19 group. CONCLUSION: Mortality in the first 90 days after COVID-19 in PD patients with COVID-19 is not different from the control PD group. However, some of these patients continue to experience significant problems, especially respiratory system symptoms, malnutrition, and hypervolemia.
ABSTRACT
BACKGROUND AND AIMS: Although existing data suggest an increased mortality rate, data about the course of coronavirus disease 2019 (COVID-19) in peritoneal dialysis (PD) patients, its short-and long-term effects on the patient and technique survival are limited. Moreover, specific factors associated with increased risk of death have not been clearly defined yet. Therefore, we aimed to study the characteristics of PD patients with COVID-19, determine the short-term mortality and other medical complications, and delineate the factors associated with COVID-19 outcome. METHOD: This national multicenter study included all PD patients who had confirmed severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection based on positive reverse transcriptase-polymerase chain reaction testing of a nasopharyngeal swab recorded in this database from the attending 27 PD centers. The demographic data, comorbidities, medications used, PD-related data were recorded as well as clinical, laboratory and radiological findings of COVID-19 and outcomes at the end of the first month were recorded. RESULTS: We enrolled 142 COVID-19 patients (median age: 52 years). A total of 58.2% of patients had mild disease at diagnosis, lung involvement was detected in 60.8% of patients. A total of 83 (58.4%) patients were hospitalized, 31 (21.8%) patients were admitted to intensive care unit and 24 needed mechanical ventilation. A total of 15 (10.5%) patients were switched to hemodialysis and hemodiafiltration was performed for 4 (2.8%) patients. Persisting pulmonary symptoms (n = 27), lower respiratory system infection (n = 12), rehospitalization for any reason (n = 24), malnutrition (n = 6), hypervolemia (n = 13), peritonitis (n = 7), ultrafiltration failure (n = 7) and in PD modality change (n = 8) were reported in survivors. During the 1 month from the diagnosis of COVID-19, 26 patients (18.31%) died. The non-survivor group was older and comorbidities were more prevalent. Fever, dyspnea, cough, serious-vital disease at presentation, bilateral pulmonary involvement and pleural effusion were more frequent among non-survivors. Age (OR:1.102;95% CI: 1.032- 1.117;P:0.004), moderate-severe clinical disease at presentation (OR:26.825;95% CI: 4.578-157.172;P < 0.001) and CRP levels (OR:1.008;95% CI;1.000-1.016;P:0.040) were associated with increased first-month mortality in multivariate analysis. CONCLUSION: Early mortality rate and medical complications are quite high in PD patients with COVID-19. Age, clinical severity of COVID-19 and baseline CRP level are the independent parameters associated with mortality.
ABSTRACT
BACKGROUND AND AIMS: Haemodialysis (HD) patients are at increased risk for adverse short-term consequences of COVID-19. In this study, we investigated the characteristics of chronic HD patients in the post-COVID-19 period and compared them with the control group. METHOD: We conducted a national multicentre observational study involving adult chronic HD patients recovering from COVID-19. The control HD group was selected from patients with similar characteristics who did not have COVID-19 in the same center. SARS-CoV-2 RT-PCR negative patients and patients in the active period of COVID-19 were not included. RESULTS: A total of 1223 patients (635 COVID-19 groups, 588 control groups) were included in the study from the data collected from 47 centres between 21 April 2021 and 11 June 2021. The patients' baseline demographics, comorbidities, medications, HD characteristics and basic laboratory tests were quite similar between the groups (Table 1). 28th-day mortality and between 28th day and 90th day mortality were higher in the COVID-19 group than in the control group [19 (3.0%) patients and 0 (0%) patients;15 (2.4%) patients and 4 (0.7%) patients, respectively]. Presence of respiratory symptoms, rehospitalization, need for home oxygen therapy, lower respiratory tract infection and A-V fistula thrombosis were significantly higher in the COVID-19 group in the first 28 days of illness and between 28 and 90 days. Mortality was significantly associated with preexisting COVID-19, age, current smoking, use of tunneled HD catheter, persistence of respiratory symptoms, rehospitalization, need for home oxygen support, presence of lower respiratory tract infection within 28 days and persistence of respiratory symptoms. CONCLUSION: In the post-COVID-19 period, mortality, rehospitalization, respiratory problems and vascular access problems are higher in maintenance HD patients who have had COVID-19 compared to control HD patients.

ABSTRACT
BACKGROUND AND AIMS: Acute kidney injury (AKI) is common in coronavirus disease-2019 (COVID-19) and the severity of AKI is linked to adverse outcomes. In this study, we investigated the factors associated with in-hospital outcomes among hospitalized patients with COVID-19 and AKI. METHOD: In this multicenter retrospective observational study, we evaluated the characteristics and in-hospital renal and patient outcomes of 578 patients with confirmed COVID-19 and AKI. Data were collected from 34 hospitals in Turkey from March 11 to June 30, 2020. AKI definition and staging were based on the Kidney Disease Improving Global Outcomes criteria. Patients with end-stage kidney disease or with a kidney transplant were excluded. Renal outcomes were identified only in discharged patients. RESULTS: The median age of the patients was 69 years, and 60.9% were males. The most frequent comorbid conditions were hypertension (70.5%), diabetes mellitus (43.8%), and chronic kidney disease (41.5%). The proportions of AKI stages 1, 2, and 3 were 54.0%, 24.7%, and 21.3%, respectively. 291 patients (50.3%) were admitted to the intensive care unit. Renal improvement was complete in 80.7% and partial in 17% of the patients who were discharged. Renal outcomes were worse in patients with AKI stage 3 or baseline CKD. The overall in-hospital mortality in patients with AKI was 38.9%. By multivariate Cox regression analysis, age (hazard ratio [HR] [95% confidence interval (95%CI)]: 1.01 [1.0-1.03], p = 0.035], male gender (HR [95%CI]: 1.47 [1.04-2.09], p = 0.029), diabetes mellitus (HR [95%CI]: 1.51 [1.06-2.17], p = 0.022) and cerebrovascular disease (HR [95%CI]: 1.82 [1.08-3.07], p = 0.023), serum lactate dehydrogenase (greater than two-fold increase) (HR [95%CI]: 1.55 [1.05-2.30], p = 0.027) and AKI stage 2 (HR [95%CI]: 1.98 [1.25-3.14], p = 0.003) and stage 3 (HR [95%CI]: 2.25 [1.44-3.51], p = 0.0001) were independent predictors of in-hospital mortality. The in-hospital mortality rates across AKI stages by age, gender, and diabetes mellitus were shown in the Figure. CONCLUSION: Advanced-stage AKI is associated with extremely high mortality among hospitalized COVID-19 patients. Age, male gender, comorbidities, which are risk factors for mortality in patients with COVID-19 in the general population, are also related to in-hospital mortality in patients with AKI. Renal problems continue in a significant portion of the patients who were discharged.
ABSTRACT
Objective: In the early stages of any epidemic caused by new emerging pathogens healthcare personnel is subject to a great risk. Pandemic caused by SARS-CoV-2, proved to be no exception. Many healthcare workers died in the early stages of pandemic due to inadequate precautions and insufficient protection. It is essential to protect and maintain the safety of healthcare personnel for the confinement of pandemic as well as continuity of qualified healthcare services which is already under strain. Educating healthcare personnel on appropiate use of personal protective equipment (PPE) is as essential as procuring them. Material and Methods: A survey is conducted on 4927 healthcare personnel working solely with pediatric patients from 32 different centers. Education given on PPE usage were questioned and analyzed depending on age, sex, occupation and region. Results: Among four thousand nine hundred twelve healthcare personnel from 32 different centers 91% (n= 4457) received education on PPE usage. Of those who received education only 36% was given both theoretical and applied education. Although there was no differences among different occupation groups, receiving education depended on regions. Conclusion: It is essential to educate healthcare personnel appropiately nationwidely for the continuity of qualified healthcare services during the pandemic.
