Abstract
Background Vaccines against coronavirus disease-19 (COVID-19) have been effective in preventing symptomatic diseases, hospitalizations, and intensive care unit (ICU) admissions. However, data regarding the effectiveness of COVID-19 vaccines in reducing mortality among critically ill patients with COVID-19 remains unclear. Aims To determine the vaccination status and investigate the impact of the COVID-19 vaccine on the 28-day mortality in critically ill patients with COVID-19. Study Design Multicenter prospective observational clinical study. Methods This study was conducted in 60 hospitals with ICUs managing critically ill patients with COVID-19. Patients aged ≥ 18 years with confirmed COVID-19 who were admitted to the ICU were included. The present study had two phases. The first phase was designed as a one-day point prevalence study, and demographic and clinical findings were evaluated. In the second phase, the 28-day mortality was evaluated. Results As of August 11, 2021, 921 patients were enrolled in the study. The mean age of the patients was 65.42 ± 16.74 years, and 48.6% (n = 448) were female. Among the critically ill patients with COVID-19, 52.6% (n = 484) were unvaccinated, 7.7% (n = 71) were incompletely vaccinated, and 39.8% (n = 366) were fully vaccinated. A subgroup analysis of 817 patients who were unvaccinated (n = 484) or who had received two doses of the CoronaVac vaccine (n = 333) was performed. The 28-day mortality rate was 56.8% (n = 275) and 57.4% (n = 191) in the unvaccinated and two-dose CoronaVac groups, respectively. The 28-day mortality was associated with age, hypertension, the number of comorbidities, type of respiratory support, and APACHE II and sequential organ failure assessment scores (p < 0.05). The odds ratio for the 28-day mortality among those who had received two doses of CoronaVac was 0.591 (95% confidence interval: 0.413-0.848) (p = 0.004). Conclusion Vaccination with at least two doses of CoronaVac within six months significantly decreased mortality in vaccinated patients than in unvaccinated patients.

Abstract
This study seeks to identify and highlight the differences in the environmental sustainability and environmental protection practices of industrialized countries. For this purpose, thirty industrialized countries were examined using a multi-criteria integrated decision model based on fourteen environmental sustainability performance criteria. An open-source software based on the Python that allows different multi-criteria decision-making methods to be used through a user-friendly interface was developed for evaluations. The results from the developed software rank Sweden first and India last in their environmental sustainability performances. Sweden stands out notably in terms of negative greenhouse gas emission technologies, afforestation, reforestation, environmental laws, carbon tax, bioenergy, and national consciousness. India, on the other hand, does not appear to handle environmental problems in a timely and appropriate manner considering its large population and development needs. Development, utilization, and expansion of renewable energy sources, waste recycling, waste reduction, proper waste disposal, and prioritization of the development of technologies with zero or negative greenhouse gas emissions have emerged as significant factors for environmentally friendly industrialization.

Abstract
Abstract
Background
Recent advancements in recanalization techniques, introduction of dedicated equipment and elaboration of systematic algorithmic approaches have significantly improved procedural success of coronary chronic total occlusion (CTO) percutaneous coronary intervention (PCI) procedures. However, despite their undisputable merits in terms of procedural success, direct comparisons of mid-term clinical and angiographic outcomes following CTO and non-CTO-PCI are missing.
Purpose
The aim of this study was to assess the clinical and angiographic outcomes of patients undergoing successful CTO-PCI as compared to a propensity matched cohort of patients undergoing PCI of non-occlusive coronary lesions.
Methods
All consecutive patients undergoing successful CTO recanalization procedures at our center between 2015 and 2018 were included (N=453; 472 lesions). For matching purposes, all patients undergoing non-CTO-PCI present in our database were included (N=14733; 23458 lesions). A 1-to-1 nearest neighbour matching using baseline clinical and angiographic variables was performed to identify one patient undergoing non-CTO-PCI (N=453; 472 vessels) for each patient undergoing CTO-PCI (N=453; 472 vessels). Surveillance angiography was scheduled at 6–9 months and clinical follow-up was performed up to 12 months. The primary clinical endpoint of interest was the incidence of major adverse cardiovascular events (MACE), a composite of all-cause death, myocardial infarction (MI) and target lesion revascularization (TLR). The secondary angiographic endpoint was in-segment binary restenosis.
Results
Patients undergoing CTO-PCI displayed a tendency towards higher degrees of binary restenosis at surveillance angiography as compared to those undergoing non-CTO-PCI (CTO vs. non-CTO: 30.5% vs. 24.0%; P=0.058), despite not meeting statistical significance. Of note, the incidence of occlusive restenosis was low and comparable between groups (2.2% vs. 1.4%; P=0.603). At 12 months follow-up, MACE occurred in 83 patients (19.7%) in the CTO-PCI and 59 patients (14.1%) in the non-CTO-PCI group (hazard ratio [HR] = 1.44; 95% confidence interval [CI]: 1.03–2.01; P=0.033). TLR rates were significantly higher following CTO- as compared to non-CTO-PCI (17.2% vs. 10.3%; HR=1.72 [1.18–2.51], P=0.005). The incidence of all-cause death (2.6% vs. 3.3%; P=0.548) and MI (0.5% vs. 1.4%; P=0.177) was not significantly different between the groups.
Conclusion
In this large, propensity-matched comparison of clinical and angiographic outcomes following CTO- vs. non-CTO-PCI, we found CTO-PCI to be associated with a higher MACE rate at 12 months, primarily driven by significantly higher TLR rates. The incidence of occlusive restenosis was low and comparable between groups.

Abstract
MicroRNAs (miRNAs) are a class of small noncoding RNAs that have major functions in the development and progression of colorectal cancer (CRC) as tumor suppressors or oncogenes. The aim of the current research was to assess the role of miR-485-3p and miR-4728-5p in the pathogenesis of CRC. In this study, fresh tumor and adjacent non-tumor tissue samples were obtained from a total of 59 CRC patients, 37 from colon and 22 from rectum. The expression profiles of miR-485-3p and miR-4728-5p were determined using qRT-PCR. miRNA-related transcription factor (TF) regulatory networks were constructed using the TransmiR v2.0, TF-regulated target genes were determined using the Human.mirFFL.DB and TRRUST v2.0, functional annotation and pathway enrichment analyses were performed using DIANA-mir-Path v3.0 and -Tarbase v7.0. The results demonstrated that the expression levels of both miR-485-3p and miR-4728-5p were very significantly downregulated in CRC tissues (fold changes = 0.42 ± 0.70 and 0.59 ± 1.06, respectively; both p = 0.000). On the other hand, lower expression levels of miR-485-3p were detected in the both rectum and colon. Moreover, the decrease in the expression levels of miR-4728-5p was correlated with increasing age. However, these differences were not statistically significant according to the FDR-related p-values (0.126 and 0.168, respectively). By bioinformatics analyses, miR-485-3p and miR-4728-5p-related TFs were identified. Some of these TFs, namely, AR, CREB1, CEBPB, FOXA1, GTF2I, MAZ, NCOR2, NFIC, NRF1, SIN3A, SREBF1, SREBF2, p53 and YY1, appeared to be associated with CRC and were, therefore, selected to construct miRNA-TF-gene networks of potential targets for the early diagnosis and treatment of CRC. Pathway enrichment analysis indicated Hippo signaling pathway as heavily regulated by miR-485-3p. It seems that the decrease in expression levels of miR-485-3p and miR-4728-5p might be associated with development of colorectal cancer.

Abstract
Abstract
Background
The efficacy and safety of ticagrelor versus prasugrel according to smoking status in patients with acute coronary syndromes (ACS) are not known.
Purpose
The aim of this study was to assess the efficacy and safety of ticagrelor versus prasugrel according to smoking status in patients with ACS undergoing invasive evaluation.
Methods
This pre-specified analysis of the ISAR-REACT 5 trial included 1349 smokers and 2652 nonsmokers randomised to receive ticagrelor or prasugrel. The primary endpoint was the incidence of death, myocardial infarction, or stroke; the secondary endpoint was the incidence of Bleeding Academic Research Consortium (BARC) type 3 to 5 bleeding. Both endpoints were assessed at 12 months after randomisation.
Results
There was no significant treatment arm-by-smoking status interaction regarding the efficacy outcome. The primary endpoint occurred in 47 patients (7.0%) in the ticagrelor group and 41 patients (6.2%) in the prasugrel group in smokers (hazard ratio [HR]=1.15; 95% confidence interval [CI] 0.76–1.75; P=0.510) and in 133 patients (10.2%) in the ticagrelor group and 94 patients (7.2%) in the prasugrel group in nonsmokers (HR=1.44 [1.10–1.87], P=0.007; Pint=0.378). The secondary endpoint occurred in 27 patients (4.6%) in the ticagrelor group and 33 patients (5.6%) in the prasugrel group in smokers (HR=0.81 [0.49–1.35]; P=0.412) and in 66 patients (6.0%) in the ticagrelor group and 46 patients (4.4%) in the prasugrel group in nonsmokers (HR=1.38 [0.94–2.01]; P=0.097).
Conlusions
Although there was no significant interaction between smoking and treatment effect, the present findings suggest a greater advantage of prasugrel over ticagrelor in nonsmoker vs. smoker patients with ACS.

Abstract
In MCDM problems, the decision maker is often ready to adopt the closest solution to the reference values in a choice or ranking problem. The reference values represent the desired results as established subjectively by the decision maker or determined through various scientific tools. In a criterion, the reference value could be the maximum value, the minimum value, or a specific value or range. Also, the acceptances degrees of ranges outside the reference may differ from each other in a criterion. Furthermore, measurements in a criterion may have been obtained with any of the nominal, ordinal, interval, and ratio scales. For the decision problems, including qualitative criteria, the solution cannot be achieved without scaling of criteria with the existing MCDM methods. The purpose of this study is to propose the Nearest Solution to References (REF) Method, a novel reference-based MCDM method, for the solution of decision problems having mixed data structure where references can be determined for criteria.

Abstract
Krukenberg tumor (KT), mostly originates from gastric cancer, is the metastatic tumor of ovaries accounting for 1-2% of all ovarian cancer. Common presenting symptoms include abdominal pain, distension, and ascites. Rests of the patients have non-specific gastrointestinal symptoms including dyspepsia, weight loss, nausea and vomiting. Gynecologic symptoms such as virilization, menstrual bleeding or irregularity and amenorrhea are much less frequent in the literature cases. Here, we present an unusual case of KT presented with amenorrhea as the sole initial symptom.

Abstract
The authors describe a modification of the classic gluteal bilateral V-Y advancement flap for sacral defect closure. After initial debridement, the V-Y design is marked on both sides of the defect. The incision is carried down to the fascia of the underlying gluteus maximus muscle. The upper and lower arms of the flaps are elevated and advanced on the gluteal muscle toward the midline, interdigitating each opposing arm. The overall result is a zigzag, broken midline suture. This procedure was carried out in 14 patients with sacral pressure sores and in 1 patient with a chronic pilonidal sinus. All flaps survived without major problems. There were no recurrences during the 6 to 16 months of follow-up. The interdigitating fasciocutaneous V-Y gluteal flap design is effective in breaking the midline vertical scar and preserving the gluteus maximus muscle.
