Role of intravenous vitamin C on outcomes in hospitalized patients with moderate or severe COVID-19: a real life data of Turkish patients.

Background: We aimed to examine the efficacy of intravenous vitamin C (IV-VC) in the treatment of hospitalized patients with moderate or severe COVID-19.

Method: We conducted a single-center and retrospective study including patients with COVID-19 diagnosis who were hospitalized. Patients were categorized into three groups as those who received low-dose (LDVC group, 2 g/day, n = 183) or high-dose IV-VC (HDVC group, 25 g/day, n = 41) and who did not receive IV-VC (control group, n = 46).

European multicentre study evaluating the prognosis of peripheral early-stage lung adenocarcinoma patients operated on by segmentectomy or lobectomy.

Objectives: To analyse impact of segmentectomy on oncological outcomes of different peripheral early-stage lung adenocarcinoma patterns.

Methods: Retrospective multicentre study including patients who underwent either lobectomy or segmentectomy in 6 European centres from 2015 to 2021, for ≤2 cm pathological peripheral lung adenocarcinoma. Overall and disease-free survivals were assessed by cox-regression and lung cancer-specific survival by competing regression analyses to adjust for patient- and tumour-related factors both in the entire dataset and the in aggressive adenocarcinoma patterns dataset.

Evaluation of risk factors and survival rates of patients with early-stage breast cancer with machine learning and traditional methods.

Background: This article is aimed to make predictions in terms of prognostic factors and compare prediction methods by using Cox proportional hazards regression analysis (CPH), some machine learning techniques and Accelerated Failure Time (AFT) model for post-treatment survival probabilities according to clinical presentations and pathological information of early-stage breast cancer patients.

Material And Methods: The study was carried out in three stages. In the first stage, the CPH method was applied.

Might the fungus candida albicans a risk factor for autism? A meta-analysis study.

Objective: Due to the high increase in rate of autism, it has gained great importance to determine the etiology of autism spectrum disorder. The purpose of our study was to assess the role of Candida albicans as a risk factor to cause autism behavior.

Methods: We searched Scopus, PubMed, Web of Science and PsycINFO for articles up to December, 2021.

Clinical performance of short fiber reinforced composite and glass hybrid on hypomineralized molars: A 36-month randomized split-mouth study.

Objectives: This study aimed to assess the clinical performance outcome at 36 months of molars with molar incisor hypomineralization and carious lesions, treated with two different restorative approaches following selective caries removal.

Methods: The children aged 6 to 12 years (18 female, 13 male) included in the study had at least two carious permanent first molars diagnosed with molar incisor hypomineralization. Sixty-two molars were restored in a split-mouth design.

Upstaged from cT1a-c to pT2a lung cancer, related to visceral pleural invasion patients, after segmentectomy: is it an indication to complete resection to lobectomy?

Objectives: Segmentectomy may be indicated for T1a-cN0 non-small-cell lung cancer. However, several patients are upstaged pT2a at final pathological examination due to visceral pleural invasion (VPI). As resection is usually not completed to lobectomy, this may raise issue of potential worse prognosis.

What is the best method for long-term survival analysis?

In the Cox proportional hazards regression model, which is the most commonly used model in survival analysis, the effects of independent variables on survival may not be constant over time and proportionality cannot be achieved, especially when long-term follow-up is required. When this occurs, it would be better to use alternative methods that are more powerful for the evaluation of various effective independent variables, such as milestone survival analysis, restricted mean survival time analysis (RMST), area under the survival curve (AUSC) method, parametric accelerated failure time (AFT), machine learning, nomograms, and offset variable in logistic regression. The aim was to discuss the pros and cons of these methods, especially with respect to long-term follow-up survival studies.

Evaluation of the effects of the toilet training process on the children's quality of life.

Background: Toilet training is a significant developmental milestone for children. During the process of toilet training, voiding and defecation problems may develop, which have a major adverse impact on the child's quality of life (QoL). The aim of this study was to assess voiding and defecation problems in the process of toilet training and evaluate how these issues influenced the children's QoL.

YouTube™ as a source of information on prostatitis: a quality and reliability analysis.

It was aimed to analyze the YouTube™ videos on prostatitis regarding their source, content, and information included. The term "prostatitis" was searched by relevance and the first 200 video links and features were recorded. Using the 5-point modified DISCERN tool, Global Quality Score (GQS), and Journal of American Medical Association (JAMA) score, the quality and reliability of the information were assessed by two urologists.

Risk factors and genetic characterization of bovine respiratory syncytial virus in the inner Aegean Region, Turkey.

Bovine respiratory syncytial virus (BRSV) is one of the causative viral agents of the bovine respiratory disease complex. This study was conducted to determine the seropositivity and risk factors associated with BRSV infection and to evaluate the phylogenetic relatedness of the BRSVs in the inner Aegean region of Turkey. In this cross-sectional study, serum samples (n = 557) and nasal swabs (n = 21) were collected from cattle herds (n = 43) between February 2018 and March 2019.

Spectral domain optical coherence tomography findings of patients with pars planitis and risk factors affecting visual acuity.

Purpose: To evaluate spectral domain optical coherence tomography (SD-OCT) findings of 42 eyes with pars planitis and to identify risk factors affecting visual acuity.

Methods: Medical records and SD-OCT findings were retrospectively reviewed.

Results: Mean best-corrected visual acuity (BCVA) was 0.

Visceral adiposity index is useful for evaluating obesity effect on erectile dysfunction.

Studies show that erectile dysfunction (ED) is associated with obesity, and it has been shown that the possibility of developing sexual dysfunction in obese men is 30% higher compared to those with normal weight. Obesity is measured using various methods, for example waist circumference (WC) measurement or body mass index (BMI), but recently, visceral adiposity index (VAI) has also been utilised to better assess obesity and metabolic syndrome. In our study, the potential link between VAI and ED was investigated.

Evaluation of adherence to Mediterranean diet in medical students at Kocaeli University, Turkey.

Introduction This study was conducted to evaluate the eating habits of medical students at Kocaeli University in northwest Turkey in terms of their ability to apply their academic knowledge regarding healthy lifestyles to their own lives using the Mediterranean Diet Quality Index (KIDMED). Methods In this cross-sectional study, a questionnaire including demographic information and the KIDMED index was administered to 354 medical school students (206 first-year and 148 third-year students). The students' sex, body mass index, KIDMED score, place of residence, smoking habit, media screen time, and regular exercising variables were evaluated.
