Electronic cigarette use and consumption patterns in medical university students.

Background: A major public health hazard is youth e-cigarette use. Although new, e-cigarette health hazards are becoming well-known in the literature. E-cigarette sale restrictions and laws differ globally. In this cross-sectional study, we studied medical university students' tobacco and e-cigarette use and characteristics in a country where sales and import of e-cigarettes are banned. The primary objective is to determine the prevalence of electronic cigarette use and understand consumption patterns among medical faculty students in this setting. Materials and methods: The questionnaire was sent using a web-based student information system. Sociodemographic features, tobacco and e-cigarette use, consumption patterns, and e-cigarette risk perceptions were covered in 54 questions. Results: The study comprised 1,054 students (48.7% male) aged 21.5 ± 2.6 years who completed the questionnaire. 37.7%, 20.9% and 23.6% have smoked cigarettes, e-cigarettes, or water pipes. Current cigarette smokers were 17.0%, e-cigarette users 4.0%, and water pipe smokers 4.5%. E-cigarette users were 52.3% dual smokers. The most common symptoms reported by e-cigarette users were cough (58.4%) and dyspnea (54.2%). Multivariable models showed that the male sex, greater monthly income, and a current smoker friend were independent risk factors for e-cigarette ever use, while the male sex, paternal current smoking, and close friends' current smoking status were risk factors for dual use among medical trainees. Many medical students who used electronic cigarettes underestimated nicotine's health hazards and harmful chemicals in e-cigarettes. Despite e-cigarette sales being prohibited in our country, 56.4% and 25.4% of e-cigarette users provided e-cigarettes from tobacco shops and through online sales, respectively. Conclusion: Medical university students use tobacco most often by smoking cigarettes. Despite medical university students being aware of the health hazards of e-cigarettes, the current use of electronic cigarettes is 4.0%. Male sex, greater monthly income, and having current smoker friends are independent risk factors for e-cigarette use, while paternal smoking is a risk factor for dual use among medical trainees. Although in the country, sales of e-cigarettes are banned, ever-use rates for e-cigarettes were remarkably high at 20.9%, and the ease of accessing e-cigarettes was striking.

Relationship between functional status and fatigue after COVID-19 infection: a multicenter study from Türkiye.

Background/aim: Symptoms of COVID-19 may persist for months. One of the persistent symptoms of COVID-19 is fatigue, which reduces functional status. The relationship between fatigue, functional status, and various other factors has received little attention, which this study aims to address.. Materials and methods: Patients with COVID-19 infection were included in this multicenter cross-sectional study. Age, sex, body mass index (BMI), marital status, smoking status, presence and duration of chronic disease, comorbidity index, regular exercise habits, time since COVID-19 diagnosis, hospitalization status, length of hospital stay, intubation status, home oxygen therapy after discharge, participation in a pulmonary rehabilitation program, presence of dyspnea, presence of cough, presence of sputum, and modified Medical Research Council, Post-COVID Functional Status (PCFS), Fatigue Severity Scale (FSS), and EQ-5D-5L Questionnaire scores were recorded. Results: We enrolled 1095 patients, including 603 (55%) men and 492 (45%) women with a mean age of 50 ± 14 years. The most common chronic lung disease was COPD (11%) and 266 (29%) patients had nonpulmonary disease. The median time elapsed since COVID-19 diagnosis was 5 months; the hospitalization rate was 47%. The median PCFS grade was 1 (0-4) and the median FSS score was 4.4 (1-7). The PCFS and FSS were positively correlated (r = 0.49, p < 0.01; OR: 1.88, 95% CI: 1.68-2.10). Both functional status and fatigue were associated with quality of life, which was lower in older patients, those with higher BMI, those with systemic disease, those not exercising regularly, and those with more severe COVID-19 infection (defined by dyspnea, pneumonia as indicated by computed tomography, hospitalization, length of stay, ICU admission, intubation, and the need for home oxygen after discharge). Conclusion: Fatigue may cause poorer functional status regardless of the time since COVID-19 diagnosis. In this study, patients with FSS scores of >4.78 showed moderate to severe functional limitations. It is important to address modifiable patient risk factors and reduce the severity of COVID-19 infection.

Efficacy of transarterial chemoembolization treatment with 30-60-µm microspheres in patients with hepatocellular carcinoma.

BACKGROUND: Chemoembolization with small drug-eluting microspheres is widely used in the treatment of hepatocellular carcinoma (HCC). OBJECTIVES: This study aimed to evaluate the efficacy and safety of transarterial chemoembolization with doxorubicin-eluting 30-60-µm microspheres (DEB-TACE) in patients with Barcelona Clinic Liver Cancer (BCLC) stage A and B HCC. MATERIALS AND METHODS: In this single-center study, 88 patients with HCC (BCLC A/B: 15.9%/84.1%) who underwent 137 DEB-TACE sessions between January 2015 and December 2020 were retrospectively assessed. Response to treatment was assessed 4-8 weeks after each DEB-TACE procedure according to mRECIST (Modified Response Evaluation Criteria in Solid Tumors) criteria. Progression-free survival (PFS), time to progression (TTP), overall survival (OS), and adverse events were recorded. RESULTS: In 88 patients (84.1% males; median age, 66.0 years; range, 22-83), the median follow-up was 17 months (range, 2-64). Eight patients (9.1%) had a complete response, 42 (47.8%) had partial regression, 10 (11.3%) had stable disease, and 28 (31.8%) had progressive disease. There was a statistically significant difference between serum alpha-fetoprotein (AFP) levels before and after DEB-TACE treatment (p < 0.001). The median OS was 17 months (95% confidence interval [CI], 10.3-23.7). Cox regression analyses found that preprocedural serum AFP level (400+ vs. < 400; p = 0.024), Child Pugh classification (B vs. A; p = 0.019), and number of DEB-TACE sessions (1 vs. > 1; p = 0.003) were independent risk factors affecting OS. The median PFS was 8 months (95% CI, 5.8-10.2) and TTP was 6 months (1-14 months). CONCLUSION: Chemoembolization with 30-60-µm microspheres is an effective and safe treatment for HCC. The number of DEB-TACE sessions is also one of the factors affecting OS.

Efficacy of Accelerated Vaccination against Hbv to Achieve Antibody formation in Multiple Sclerosis Patients Receiving Anti-Cd20 Therapy.

Aim: Ocrelizumab is a monoclonal antibody that has been approved for use in both relapsing-remitting multiple sclerosis (RRMS) and primary progressive multiple sclerosis (PPMS). Since ocrelizumab acts on B cells, it also affects humoral immunity, thus reducing the vaccine response. In this study, we aimed to elucidate the relationship between the antibody response following rapid vaccination against hepatitis B virus (HBV) in multiple sclerosis (MS) patients receiving ocrelizumab treatment, and the time of vaccination. Materials and Methods: A total of 220 MS patients were included in this retrospective analysis. The patients' baseline HBV serostatuses (HbsAg, Anti-HbsAb, Anti-HbcAb), previous drug history for MS, whether they were vaccinated against HBV in the past, vaccination status before or after ocrelizumab treatment, and protective antibody titers according to vaccination times, occult HBV incidence and initiation of antiviral treatment were evaluated. Results: Forty-nine percent of MS patients using ocrelizumab were not vaccinated against HBV. The patients were divided into three groups according to their vaccination status as: individuals vaccinated in the past (7.3%, n = 16), vaccinated before treatment (4.5%, n = 10), and vaccinated after treatment (22.3%, n = 49). The antibody titers of the patients in the 6th month after ocrelizumab treatment were measured as 78 mIU/ml, 193 mIU/ml, and 0, respectively. The number of patients with occult HBV infection was 38. Conclusion: In patients with a suspected diagnosis of MS, HBV serostatus should be evaluated at the beginning and if necessary, patients should be vaccinated in the early period. Vaccinating patients at least 1 month before initiating multiple sclerosis treatment is more effective in terms of protective antibody formation.

Internal versus external biliary drainage in malignant biliary obstructions: is there a difference in the rate of infection?

BACKGROUND: Percutaneous biliary drainage is a frequently used method to provide biliary decompression in patients with biliary obstruction. PURPOSE: To investigate the between drainage type and infection risk in patients treated with internal-external and external biliary drainage catheterization for malignant biliary obstruction. MATERIAL AND METHODS: A total of 410 patients with malignant biliary obstruction who underwent internal-external or external biliary drainage catheterization between January 2012 and October 2016 were retrospectively evaluated. We investigated the correlation between percutaneous biliary drainage technique and infection frequency by evaluating patients with clinical findings, bile and blood cultures, complete blood counts, and blood biochemistry. RESULTS: There was no statistically significant difference between the selected patient groups (internal-external or external biliary drainage catheter placed) in terms of age, sex, primary diagnosis, receiving chemotherapy, catheter sizes, and outpatient-patient status. After catheterization, catheter-related infection was observed in 49 of 216 (22.7%) patients with internal-external and 18 of 127 (14.2%) patients with external biliary drainage catheters, according to the defined criteria. There was no difference in infection rate after the biliary drainage in the two groups (P > 0.05). There was also no difference concerning frequently proliferating microorganisms in bile cultures. CONCLUSION: Internal-external biliary drainage catheter placement does not bring an additional infection risk for uninfected cholestatic patients whose obstruction could be passed easily in the initial drainage.

Specificity and sensitivity of the SeLECT score in predicting late seizures in patients undergoing intravenous thrombolytic treatment and the effect of diabetes mellitus and leukoaraiosis.

BACKGROUND: Seizures after stroke can negatively affect the prognosis of ischemic stroke and cause a decrease in quality of life. The efficacy of intravenous (IV) recombinant tissue plasminogen activator (rt-PA) treatment in acute ischemic stroke has been demonstrated in many studies, and IV rt-PA treatment has been increasingly used around the world. The SeLECT score is a useful score for the prediction of late seizures after stroke and includes the severity of stroke (Se), large artery atherosclerosis (L), early seizure (E), cortical involvement (C), and the territory of the middle cerebral artery (T). However, the specificity and sensitivity of the SeLECT score have not been studied in acute ischemic stroke patients that received IV rt-PA treatment. OBJECTIVE: In the present study, we aimed to validate and develop the SeLECT score in acute ischemic stroke patients receiving IV rt-PA treatment. METHODS: The present study included 157 patients who received IV thrombolytic treatment in our third-stage hospital. The 1-year seizure rates of the patients were detected. SeLECT scores were calculated. RESULTS: In our study, we found that the SeLECT score had low sensitivity but high specificity for predicting the likelihood of late seizure after stroke in patients administered IV rt-PA therapy. In addition to the SeLECT score, we found that the specificity and sensitivity were higher when we evaluated diabetes mellitus (DM) and leukoaraiosis. CONCLUSION: We found that DM was an independent risk factor for late seizures after stroke in a patient group receiving thrombolytic therapy, and late seizures after stroke were less frequent in patients with leukoaraiosis.

ANTECEDENTES: As convulsões após o AVC podem afetar negativamente o prognóstico do AVC isquêmico e causar uma diminuição na qualidade de vida. A eficácia do tratamento com ativador do plasminogênio tecidual recombinante (rt-PA) intravenoso (IV) no AVC isquêmico agudo foi demonstrada em muitos estudos, e o tratamento com rt-PA IV tem sido cada vez mais usado em todo o mundo. A pontuação SeLECT é uma pontuação útil para a previsão de convulsões tardias após AVC e inclui a gravidade do AVC (Se), aterosclerose de grandes artérias (L), convulsão precoce (E), envolvimento cortical (C) e o território do meio artéria cerebral (T). No entanto, a especificidade e a sensibilidade do escore SeLECT não foram estudadas em pacientes com AVC isquêmico agudo que receberam tratamento IV com rt-PA. OBJETIVO: No presente estudo, objetivamos validar e desenvolver o escore SeLECT em pacientes com AVC isquêmico agudo recebendo tratamento IV com rt-PA. MéTODOS: O presente estudo incluiu 157 pacientes que receberam tratamento trombolítico IV em nosso hospital de terceiro estágio. As taxas de convulsão de 1 ano dos pacientes foram detectadas. Os escores SeLECT foram calculados. RESULTADOS: Em nosso estudo, descobrimos que o escore SeLECT apresentou baixa sensibilidade, mas alta especificidade para prever a probabilidade de convulsão tardia após AVC em pacientes que receberam terapia IV com rt-PA. Além do escore SeLECT, descobrimos que a especificidade e a sensibilidade foram maiores quando avaliamos diabetes mellitus (DM) e leucoaraiose. CONCLUSãO: Descobrimos que DM foi um fator de risco independente para convulsões tardias após AVC em um grupo de pacientes recebendo terapia trombolítica, e convulsões tardias após AVC foram menos frequentes em pacientes com leucoaraiose.

Caries-related and Preventive Dental Care of 5-, 12-, and 15-year-old Syrians in Bursa, Türkiye.

Objectives: Türkiye has implemented an open-door policy for Syrians since the beginning of the Syrian crisis in 2011 and has been providing medical and dental services for Syrian asylum seekers. Bursa, being the 5th largest city in the Western region of the Turkish Republic, hosts 1,83,355 registered Syrians. The present study was designed to analyze the caries-related dental services and preventive applications among 5-, 12-, and 15-year-old Syrian patients admitted to a state-affiliated dental hospital in Bursa, Türkiye. Design: This study comprises retrospective data analysis. Place and duration of study: The data from 1st January 2016 to 1st September 2021 were derived from the Bursa Oral and Dental Health Training and Research Hospital. Materials and methods: The dental records of Syrian patients aged 5, 12, and 15 years were reviewed for caries-related (restorations, extractions, and root canal treatments) and preventive applications (fissure sealants and topical fluoridation); others were excluded. Results: A total of 3,388 dental records of 1,179 Syrian children aged 5 (N = 369), 12 (N = 498), and 15 (N = 312) years were analyzed. The highest percentages of dental services offered to 5-, 12-, and 15-year-old were "tooth extractions" (n = 369; 42.2%), "fissure sealants" (n = 555; 33.7%), and "restorative treatments" (n = 384; 44.4%), respectively (p < 0.001). Considering all years (2016-2021), male subjects [odds ratio (OR)-1.42, 95% confidence interval (CI) 1.09-1.85; p = 0.01] and 12-year-old (OR-1.87, 95% CI 1.31-2.66; p = 0.001) were more likely to visit a dentist more than once per year. Conclusion: Caries-related dental services, which are an indicator of poor oral health, are common in 5-, 12-, and 15-year-old Syrian patients.

Comparison of central corneal thickness measured by ultrasound pachymetry, corneal topography, spectral domain- optical coherence tomography, and non-contact specular microscopy.

BACKGROUND: This study aims to investigate the compatibility of central corneal thickness (CCT) measurements obtained with spectral-domain optical coherence tomography (SD-OCT), Scheimpflug-Placido-based corneal topography (CT), non-contact specular microscopy (NCSM), and ultrasonic pachymetry (UP). These four corneal measurement techniques have not been compared in a single study on these many subjects. METHODS: CCT was measured in 185 eyes of 185 volunteers with each of the four devices by a single observer. CCTs from Optovue® iVue SD-OCT, Sirius corneal topography, NonconRobo NCSM, and Accutom UP devices were recorded. Compatibility between devices was evaluated with intraclass correlation coefficient (ICC) and Bland-Altman plots. Pairwise comparisons were performed using the Bonferroni test. Measurement differences between devices were analyzed with the Pearson correlation coefficient. RESULTS: Of the 185 volunteers, 103 were men, and 82 were women. Their mean age was 48.55 ± 16.6 (18-70) years. Mean CCT values measured by UP, CT, OCT, and NCSM were 546.77 ± 39.2, 535.29 ± 39.2, 526.49 ± 39.05, 505.15 ± 46.1 µm, respectively. Statistically significant differences were found between the mean CCT values obtained from the paired devices (p <0.001). The highest difference between pairs was found between UP and NCSM (43.63 ± 1.8 µm; CI 38.74 to 48.5 µm; p <0.001), while the lowest difference was found between OCT and CT (7.3 ± 1.5 µm; 95%CI 3.1 to 11.6 µm; p <0.001). In pairwise comparisons of four devices, the highest ICC value was between UP and CT (ICC: 0.899, 95%CI 0.759-0.947; p <0.001). CONCLUSION: Despite the high correlation between measurements obtained from different methods, notable differences in CCT values exist, rendering devices non-interchangeable. Therefore, alternative brands of the same device may yield different outcomes.

Three dimensional development and asymmetry of the corpus callosum in the 0-18 age group: A retrospective magnetic resonance imaging study.

Most of the corpus callosum (CC) developmental studies are concerned with its two-dimensional structure. Linear and area measurements do not directly assess the CC size but estimate the overall structure from the cross-sectional image. This study investigated age- and sex-related changes in volumetric development and asymmetry of CC from birth to 18. For this retrospective study, we selected 696 patients (329 [47.27%] females) with both 3D-T1-weighted sequence and normal radiological anatomy from patients 0-18 years of age who had brain magnetic resonance imaging (MRI) between 2012 and 2020. The genu, body, splenium, and total volume of CC were calculated using MRICloud. The measurement results of 23 age groups were analyzed with SPSS (ver.28). Total CC volume was 18740.76 ± 4314.06 mm3 between 0 and 18 years of age, and its ratio to total brain volume (TBV) was 1.70% ± 0.23%. We observed that the total CC volume has six developmental periods 0 years, 1, 2-4, 5-9, 10-16, and 17-18 years. Genu and body grew in five developmental periods, while splenium in seven. There was intermittent sexual dimorphism in the CC volume in the first 4 years of life (p < 0.05). However, sex factor was insignificant in CC ratio to TBV. Total CC was right lateralized on average 1.81% (ranging -0.59% to 4.52%). Genu was 8.70% lateralized to the right, the body was 2.99% to the left, and the splenium was 1.41% to the right. The three-dimensional development of CC agreed with the two-dimensional developmental data of CC except for some differences.

Relationship between neurogenic bowel dysfunction severity and functional status, depression, and quality of life in individuals with spinal cord injury.

Objectives/Context: To evaluate the relationship between severity of neurogenic bowel dysfunction (NBD) and functional status, depression, and quality of life in individuals with spinal cord injury (SCI) and to determine the factors associated with developing moderate-to-severe NBD.Design: Cross-sectional study.Setting: University hospital rehabilitation outpatient clinic.Participants: Individuals with traumatic SCI, at least one year post-injury (N = 92).Interventions: Not applicable.Main Outcome Measures: Neurogenic Bowel Dysfunction Score, Functional Independence Measure (FIM), Beck Depression Inventory (BDI), and Short Form-36 (SF-36).Results: In the current sample, we found that half of the individuals with SCI had moderate-to-severe NBD. Individuals with moderate and severe NBD had lower motor FIM (P = 0.008 and P = 0.006, respectively) and SF-36 physical functioning (PF) scale (P = 0.020 and P = 0.031, respectively) scores than individuals with very minor NBD. There was no difference in the BDI scores among individuals with different levels of NBD. Individuals with American Spinal Injury Association Impairment Scale (AIS) A injuries were more likely to develop moderate-to-severe NBD than those with AIS C (odds ratio (OR) = 6.52; 95% confidence interval (CI) 1.13-37.79; P = 0.005) or AIS D (OR = 17.19; 95% CI 3.61-81.82; p < 0.001) injuries.Conclusion: Individuals with moderate-to-severe NBD had higher levels of dependency in activities of daily living and lower SF-36 PF scale scores than individuals with very minor NBD. Among individuals with SCI, completeness of injury was a significant factor for developing moderate-to-severe NBD.

Morphological evaluation of the normal and hydrocephalic third ventricle on cranial magnetic resonance imaging in children: a retrospective study.

BACKGROUND: Third ventricle morphological changes reflect changes in the ventricular system in pediatric hydrocephalus, so visual inspection of the third ventricle shape is standard practice. However, normal pediatric reference data are not available. OBJECTIVE: To investigate both the normal development of the third ventricle in the 0-18-year age group and changes in its biometry due to hydrocephalus. MATERIALS AND METHODS: For this retrospective study, we selected individuals ages 0-18 years who had magnetic resonance imaging (MRI) from 2012 to 2020. We included 700 children (331 girls) who had three-dimensional (3-D) T1-weighted sequences without and 25 with hydrocephalus (11 girls). We measured the distances between the anatomical structures limiting the third ventricle by dividing the third ventricle into anterior and posterior regions. We made seven linear measurements and three index calculations using 3DSlicer and MRICloud pipeline, and we analyzed the results of 23 age groups in normal and hydrocephalic patients using SPSS (v. 23). RESULTS: Salient findings are: (1) The posterior part of the third ventricle is more affected by both developmental and hydrocephalus-related changes. (2) For third ventricle measurements, gender was insignificant while age was significant. (3) Normal third ventricular volumetric development showed a segmental increase in the 0-18 age range. The hydrocephalic third ventricle volume cut-off value in this age group was 3 cm3. CONCLUSION: This study describes third ventricle morphometry using a linear measurement method. The ratios defined in the midsagittal plane were clinically useful for diagnosing the hydrocephalic third ventricle. The linear and volumetric reference data and ratios are expected to help increase diagnostic accuracy in distinguishing normal and hydrocephalic third ventricles.

Long-term Results of Splenectomy in Transfusion-dependent Thalassemia.

Splenectomy is indicated in transfusion-dependent thalassemia (TDT) only in certain situations. This study aimed to present the effectiveness, complications, and long-term follow-up results of splenectomy in children with TDT. We performed a 30-year single-institution analysis of cases of splenectomy for TDT between 1987 and 2017 and their follow-up until 2021. A total of 39 children (female/male: 24/15) were included. The mean age at splenectomy was 11.2±3.2 years, and their mean follow-up duration after splenectomy was 21.5±6.4 years. Response was defined according to the patient's annual transfusion requirement in the first year postsplenectomy and on the last follow-up year. Complete response was not seen in any of the cases; partial response was observed in 32.3% and no response in 67.6%. Thrombocytosis was seen in 87% of the patients. The platelet counts of 7 (17.9%) patients were >1000 (10 9 /L), and aspirin prophylaxis was given to 22 (56.4%) patients. Complications were thrombosis in 2 (5.1%) patients, infections in 11 (28.2%) patients, and pulmonary hypertension in 4 (10.2%) patients. Our study showed that after splenectomy, the need for transfusion only partially decreased in a small number of TDT patients. We think splenectomy can be delayed with appropriate chelation therapy up to higher annual transfusion requirement values.

Serum Krebs von den Lungen-6: promising biomarker to differentiate CPFE from IPF.

Background   Combined pulmonary fibrosis and emphysema (CPFE) has been recognised as a phenotype of pulmonary fibrosis. We aimed to compare serum surfactant protein-A (SP-A), surfactant protein-D (SP-D) and Krebs von den Lungen-6 (KL-6) levels, functional parameters, in CPFE and  IPF (idiopathic pulmonary fibrosis) patients. Methods Patients diagnosed with 'CPFE' and 'IPF' were consecutively included in 6 months as two groups. The patients with connective tissue diseases are excluded. Results           In this study, 47 patients (41 males, 6 females) with CPFE (n = 21) and IPF (n = 26) with a mean age of 70.12 ± 8.75 were evaluated. CPFE patients were older, had more intense smoking history, had lower DLCO/VA, lower FVC, and worse six-minute walking distance than the IPF group (p=0.005, p=0.027, p=0.02, p<0.001, p=0.001, respectively). Serum KL-6 levels were higher in CPFE group compared to IPF group [264.70 U/ml (228.90-786) vs 233.60 (101.8-425.4), p<0.001]. Serum KL-6 levels of 245.4 U/ml and higher have 81% sensitivity and 73% specificity for the discrimination of CPFE from IPF. Conclusions   Our study has shown that serum KL-6 level is a promising biomarker to differentiate CPFE from IPF. In CPFE cases respiratory and functional parameters are worse than those of pure fibrosis cases.

Hypothalamic volume and asymmetry in the pediatric population: a retrospective MRI study.

This study investigated age- and sex-related changes in the volumetric development and asymmetry of the normal hypothalamus from birth to 18. Individuals aged 0-18 with MRI from 2012 to 2020 were selected for this retrospective study. Seven hundred individuals (369 [52.7%] Males) who had 3D-T1 sequences and were radiologically normal were included in the study. Hypothalamus volume was calculated using MRICloud automated segmentation pipelines. Hypothalamus asymmetry was calculated as the difference between right and left volumes divided by the mean (in percent). The measurement results of 23 age groups were analyzed with SPSS (ver.23). The mean hypothalamic volume in the first year of life reached 69% of the mean hypothalamic volume between 0 and 18 years (1119.01 ± 196.09 mm3), 88% in the second year. The mean volume of the hypothalamus without mammillary body increased in the five-age segment, while it increased in the six-age segment with mammillary body. Although the hypothalamus volumes of males were larger than females in all age groups, a significant difference was found between the age groups of 3-8 and 12-18 years (p < 0.05). In the pediatric brain, the hypothalamus was right-lateralized between 2.39% and 14.02%. The first 2 years of life were critical in the volumetric development of the hypothalamus. A segmental and logarithmic increase in the hypothalamus volume was demonstrated. In the pediatric brain, asymmetry and sexual dimorphism were detected in the hypothalamus. Information on normal hypothalamus structure and development facilitates the recognition of abnormal developmental trajectories.

Prognostic factors for COVID-19 patients.

INTRODUCTION: Determining prognostic factors in patients with coronavirus disease (COVID-19) can have great impact on treatment planning and follow-up strategies. Herein, we aimed to evaluate prognostic factors and clinical scores for confirmed COVID-19 patients in a tertiary-care hospital in the Bursa region of Turkey. METHODOLOGY: Patients who had been diagnosed with COVID-19 microbiologically and/or radiologically between March and October 2020 in a tertiary-care university hospital were enrolled retrospectively. Adult patients (≥ 18 years) with a clinical spectrum of moderate, severe, or critical illness were included. The dependent variable was 30-day mortality and logistic regression analysis was used to evaluate any variables with a significant p value (< 0.05) in univariate analysis. RESULTS: A total of 257 patients were included in the study. The mortality rate (30-day) was 14.4%. In logistic regression analysis, higher scores on sequential organ failure assessment (SOFA) (p < 0.001, odds ratio (OR) = 1.86, 95% CI = 1.42-2.45) and CURB-65 pneumonia severity criteria (p = 0.001, OR = 2.60, 95% CI = 1.47-4.57) were found to be significant in predicting mortality at admission. In deceased patients, there were also significant differences between the baseline, day-3, day-7, and day-14 results of D-dimer (p = 0.01), ferritin (p = 0.042), leukocyte (p = 0.019), and neutrophil (p = 0.007) counts. CONCLUSIONS: In our study of COVID-19 patients, we found that high SOFA and CURB-65 scores on admission were associated with increased mortality. In addition, D-dimer, ferritin, leukocyte and neutrophil counts significantly increased after admission in patients who died.

Examining knowledge and traditional practices of mothers with children under five in Turkey on diarrhoea according to education levels.

BACKGROUND: Diarrhoea still ranks among the top causes of the deaths of children under five years old in the world. In solving this important health problem, it is necessary and imperative to know the health-related knowledge levels of mothers who take care of the child individually and the traditional practices they perform when their children are sick, in order to provide effective health education. AIM: This study aims to examine the knowledge levels and traditional practices of mothers with children younger than 5 years old regarding diarrhoea in relation to their education levels. METHODS: We conducted a cross-sectional web-based survey. The population of this cross-sectional study consisted of mothers with children under the age of 5 who lived in the metropolitan city Bursa in the South Marmara Region of Turkey. The survey was applied among the mothers of children under the age of 5 using the snowball sampling method via mobile platforms. The data were collected via Google Forms using a "Socio-Demographic Data Collection Form", an "Information Form on Measuring the Knowledge Level of Mothers on Diarrhoea" and a "Form on Main Traditional Practices Used When Children Have Diarrhoea in Turkey" prepared by the researchers after a review of the relevant literature. RESULTS: In the study, the mean total diarrhoea knowledge score of the participating mothers was found to be 22.01 ± 3.72 (high). Multiple linear regression analysis was used to determine the relationship between the total diarrhoea knowledge scores of the participants and other variables. The difference in the knowledge scores based on education levels was statistically significant (p < .001). The most prevalently preferred traditional practice in the case of children's diarrhoea was "feeding the child banana" (92.5%). CONCLUSION: Maternal education level is determined to be a significant variable that positively affects diarrhoea knowledge levels.KEY MESSAGESDiarrhoea continues to be among the top five preventable causes of death in the world and Turkey among children under the age of 5.The knowledge level of mothers about diarrhoea plays an important role in diarrhoea management. The level of knowledge about diarrhoea differs according to the education level of mothers.Traditional practices have an important place in the management of diarrhoea by mothers.

Air pollution and pediatric respiratory hospital admissions in Bursa, Turkey: A time series study.

We aimed to investigate the relation between air pollution and the number of daily hospitalizations due to pneumonia, asthma, bronchitis in children aged 0-18 in Bursa city of Turkey, between the years 2013-2018. The daily values of air pollutants (PM10, SO2, NO2, NOx, CO, and O3) from 2013 until 2018, were obtained. Adjusted Quasi-Poisson regression models including distributed lags, controlled for climate variables were used for data analysis. Increases in SO2, ozone, PMs, and nitrogen oxides were associated with pneumonia hospitalizations, increases in SO2 NOx and PMs were associated with asthma hospitalizations, and increases in SO2 and ozone were associated with bronchitis hospitalizations. Male hospitalization was related with SO2, ozone, and NOx; while female hospitalization was only related with SO2. This study showed that short-term exposure to air pollution is associated with an increased risk of pneumonia, asthma, and bronchitis hospitalization among children in Bursa.

Diagnostic value of the CSF levels of D-Lactate and pro-inflammatory cytokines (TNF-alpha, IL-6, IL-8 and IL-17) in the patients with suspected nosocomial meningitis.

INTRODUCTION: This study aims to determine the diagnostic value of IL-6, IL-8, IL-17, TNF-α and D-lactate levels in the cerebrospinal fluid (CSF) in nosocomial meningitis. METHODS: CSF levels of cytokines and D-lactate were compared across 29 episodes who were diagnosed with nosocomial meningitis, 38 episodes with pleocytosis but without meningitis and 54 control subjects. RESULTS: CSF levels of IL-6, IL-8, and D-lactate were higher in the group with nosocomial meningitis compared to the control group and to the group with pleocytosis without meningitis (p<0.05). For the levels of IL-6, when the threshold was considered to be > 440 pg/mL, the sensitivity and specificity were 55.17% and 94.74%, respectively. For IL-8 levels, when the threshold was considered to be >1249 pg/mL, the sensitivity and specificity were 44.83% and 84.21%, respectively. In the patients with nosocomial meningitis, when the threshold of D-lactate levels was considered to be >1.05µmol/mL, the sensitivity and specificity were found to be 75.86% and 63.16%, respectively. In the pleocytosis without meningitis CSF samples and in the CSF samples diagnosed with nosocomial meningitis, the highest AUC was calculated for triple combination model of IL-6, IL-8, and D-lactate levels (AUC= 0.801, p<0.001), and double combination model IL-6 and IL-8 (AUC= 0.790) (p<0.001). CONCLUSION: In our study, we have concluded that IL-6, IL-8 and D-lactate levels could be diagnostic markers for nosocomial meningitis.

Effects of the COVID-19 pandemic on the follow-up and treatment of patients with idiopathic pulmonary fibrosis: a cross-sectional, multicentre phone call survey.

OBJECTIVE: To learn about the attitudes and behaviours of patients with idiopathic pulmonary fibrosis (IPF) in relation to the difficulties experienced during the COVID-19 pandemic. DESIGN: A cross-sectional, multicentre phone call survey. SETTING: Four university hospitals in Turkey. PARTICIPANTS: The study included patients with IPF receiving antifibrotics for at least 3 months and with doctor appointment and/or scheduled routine blood analysis between March and May 2020 (the first 3 months after the official announcement of the COVID-19 pandemic in Turkey). INTERVENTIONS: Phone calls (a 5 min interview) were performed in June 2020. A questionnaire and the Hospital Anxiety-Depression Scale were applied. MAIN OUTCOME MEASURES: Patients' preferences for disease monitoring, patients' attitudes and behaviours towards IPF, drug continuation, COVID-19 diagnosis and anxiety/depression status. RESULTS: The study included 115 patients with IPF (82 male; mean age, 68.43±7.44 years). Of the patients, 73.9% had doctor appointment and 52.2% had scheduled routine blood testing; 54.5% of patients with doctor appointment self-cancelled their appointments and 53.3% of patients with scheduled routine blood testing did not undergo testing. Of the patients, 32.2% were on nintedanib and 67.8% were on pirfenidone; self-initiated drug discontinuation rate was 22.6%. The percentage of patients communicating with their physicians was 35.7%. The route of communication was by phone (34.8%). The frequency of depression and anxiety was 27.0% and 38.3%, respectively. The rates of drug discontinuation (35.1% vs 16.7%, p<0.05) and depression (37.8% vs 21.8%, p=0.07) were higher in nintedanib users than in pirfenidone users. Only two (1.7%) patients had COVID-19 diagnosis. CONCLUSIONS: During the COVID-19 pandemic, a significant proportion (>50%) of patients self-cancelled their appointments and nearly a quarter of patients discontinued their medications. Providing a documentation of the problems experienced by patients with IPF about management of the necessary requirements during the COVID-19 pandemic, this study may be a model for patients with chronic diseases.
