Um Stent Mal Colocado na Artéria Septal Perfurante: Fístula Ventricular Direita, Hematoma do Septo Interventricular e Obstrução da Via de Saída do Ventrículo Direito
Resumo As fístulas coronário-camerais, embora consideradas em sua maioria como entidades congênitas, também têm sido encontradas como complicações de grandes traumas e intervenções coronárias percutâneas (ICPs).1 Por outro lado, o hematoma do septo interventricular (SIV) pode potencialmente surgir principalmente durante intervenções de oclusão total crônica retrógrada (OTC) e tem um curso benigno nesse contexto.2 Aqui, descrevemos uma complicação desafiadora da ICP (e sua estratégia de manejo) apresentando hematoma do SIV, fístula ventricular direita e obstrução da via de saída do ventrículo direito (VSVD) devido a um stent coronário mal implantado na artéria septal perfurante (ASP)
Real-world efficacy and safety of Ledipasvir plus Sofosbuvir and Ombitasvir/Paritaprevir/Ritonavir +/- Dasabuvir combination therapies for chronic hepatitis C: A Turkish experience
Background/Aims: This study aimed to evaluate the real-life efficacy and tolerability of direct-acting antiviral treatments for patients with chronic hepatitis C (CHC) with/without cirrhosis in the Turkish population.Material and Methods: A total of 4,352 patients with CHC from 36 different institutions in Turkey were enrolled. They received ledipasvir (LDV) and sofosbuvir (SOF)+/- ribavirin (RBV) ombitasvir/paritaprevir/ritonavir +/- dasabuvir (PrOD)+/- RBV for 12 or 24 weeks. Sustained virologic response (SVR) rates, factors affecting SVR, safety profile, and hepatocellular cancer (HCC) occurrence were analyzed.Results: SVR12 was achieved in 92.8% of the patients (4,040/4,352) according to intention-to-treat and in 98.3% of the patients (4,040/4,108) according to per-protocol analysis. The SVR12 rates were similar between the treatment regimens (97.2%-100%) and genotypes (95.6%-100%). Patients achieving SVR showed a significant decrease in the mean serum alanine transaminase (ALT) levels (50.90 +/- 54.60 U/L to 17.00 +/- 14.50 U/L) and model for end-stage liver disease (MELD) scores (7.51 +/- 4.54 to 7.32 +/- 3.40) (p<0.05). Of the patients, 2 were diagnosed with HCC during the treatment and 14 were diagnosed with HCC 37.0 +/- 16.0 weeks post-treatment. Higher initial MELD score (odds ratio [OR]: 1.92, 95% confidence interval [CI]: 1.22-2.38; p=0.023]), higher hepatitis C virus (HCV) RNA levels (OR: 1.44, 95% CI: 1.31-2.28; p=0.038), and higher serum ALT levels (OR: 1.38, 95% CI: 1.21-1.83; p=0.042) were associated with poor SVR12. The most common adverse events were fatigue (12.6%), pruritis (7.3%), increased serum ALT (4.7%) and bilirubin (3.8%) levels, and anemia (3.1%).Conclusion: LDV/SOF or PrOD +/- RBV were effective and tolerable treatments for patients with CHC and with or without advanced liver disease before and after liver transplantation. Although HCV eradication improves the liver function, there is a risk of developing HCC.Turkish Association for the Study of The Liver (TASL
Recent Advances in Health Biotechnology During Pandemic
The outbreak of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which
emerged in 2019, cut the epoch that will make profound fluctuates in the history of the world
in social, economic, and scientific fields. Urgent needs in public health have brought with
them innovative approaches, including diagnosis, prevention, and treatment. To exceed the
coronavirus disease 2019 (COVID-19) pandemic, various scientific authorities in the world
have procreated advances in real time polymerase chain reaction (RT-PCR) based diagnostic
tests, rapid diagnostic kits, the development of vaccines for immunization, and the purposing
pharmaceuticals for treatment. Diagnosis, treatment, and immunization approaches put for-
ward by scientific communities are cross-fed from the accrued knowledge of multidisciplinary
sciences in health biotechnology. So much so that the pandemic, urgently prioritized in the
world, is not only viral infections but also has been the pulsion in the development of novel
approaches in many fields such as diagnosis, treatment, translational medicine, virology, mi-
crobiology, immunology, functional nano- and bio-materials, bioinformatics, molecular biol-
ogy, genetics, tissue engineering, biomedical devices, and artificial intelligence technologies.
In this review, the effects of the COVID-19 pandemic on the development of various scientific
areas of health biotechnology are discussed

Objective: Turner syndrome (TS) is a chromosomal disorder caused by complete or partial X chromosome monosomy that manifests various clinical features depending on the karyotype and on the genetic background of affected girls. This study aimed to systematically investigate the key clinical features of TS in relationship to karyotype in a large pediatric Turkish patient population.Methods: Our retrospective study included 842 karyotype-proven TS patients aged 0-18 years who were evaluated in 35 different centers in Turkey in the years 2013-2014.Results: The most common karyotype was 45,X (50.7%), followed by 45,X/46,XX (10.8%), 46,X,i(Xq) (10.1%) and 45,X/46,X,i(Xq) (9.5%). Mean age at diagnosis was 10.2±4.4 years. The most common presenting complaints were short stature and delayed puberty. Among patients diagnosed before age one year, the ratio of karyotype 45,X was significantly higher than that of other karyotype groups. Cardiac defects (bicuspid aortic valve, coarctation of the aorta and aortic stenosis) were the most common congenital anomalies, occurring in 25% of the TS cases. This was followed by urinary system anomalies (horseshoe kidney, double collector duct system and renal rotation) detected in 16.3%. Hashimoto's thyroiditis was found in 11.1% of patients, gastrointestinal abnormalities in 8.9%, ear nose and throat problems in 22.6%, dermatologic problems in 21.8% and osteoporosis in 15.3%. Learning difficulties and/or psychosocial problems were encountered in 39.1%. Insulin resistance and impaired fasting glucose were detected in 3.4% and 2.2%, respectively. Dyslipidemia prevalence was 11.4%.Conclusion: This comprehensive study systematically evaluated the largest group of karyotype-proven TS girls to date. The karyotype distribution, congenital anomaly and comorbidity profile closely parallel that from other countries and support the need for close medical surveillance of these complex patients throughout their lifespa
The frequency of Duchenne muscular dystrophy/Becker muscular dystrophy and Pompe disease in children with isolated transaminase elevation: results from the observational VICTORIA study
IntroductionElevated transaminases and/or creatine phosphokinase can indicate underlying muscle disease. Therefore, this study aims to determine the frequency of Duchenne muscular dystrophy/Becker muscular dystrophy (DMD/BMD) in male children and Pompe disease (PD) in male and female children with isolated hypertransaminasemia.MethodsThis multi-center, prospective study enrolled patients aged 3–216 months with serum alanine transaminase (ALT) and/or aspartate transaminase (AST) levels >2× the upper limit of normal (ULN) for ≥3 months. Patients with a known history of liver or muscle disease or physical examination findings suggestive of liver disease were excluded. Patients were screened for creatinine phosphokinase (CPK) levels, and molecular genetic tests for DMD/BMD in male patients and enzyme analysis for PD in male and female patients with elevated CPK levels were performed. Genetic analyses confirmed PD. Demographic, clinical, and laboratory characteristics of the patients were analyzed.ResultsOverall, 589 patients [66.8% male, mean age of 63.4 months (standard deviation: 60.5)] were included. In total, 251 patients (188 male and 63 female) had CPK levels above the ULN. Of the patients assessed, 47% (85/182) of male patients were diagnosed with DMD/BMD and 1% (3/228) of male and female patients were diagnosed with PD. The median ALT, AST, and CPK levels were statistically significantly higher, and the questioned neurological symptoms and previously unnoticed examination findings were more common in DMD/BMD patients than those without DMD/BMD or PD (p < 0.001).DiscussionQuestioning neurological symptoms, conducting a complete physical examination, and testing for CPK levels in patients with isolated hypertransaminasemia will prevent costly and time-consuming investigations for liver diseases and will lead to the diagnosis of occult neuromuscular diseases.

Reducing the environmental impact of surgery on a global scale: systematic review and co-prioritization with healthcare workers in 132 countries
Abstract
Background
Healthcare cannot achieve net-zero carbon without addressing operating theatres. The aim of this study was to prioritize feasible interventions to reduce the environmental impact of operating theatres.
Methods
This study adopted a four-phase Delphi consensus co-prioritization methodology. In phase 1, a systematic review of published interventions and global consultation of perioperative healthcare professionals were used to longlist interventions. In phase 2, iterative thematic analysis consolidated comparable interventions into a shortlist. In phase 3, the shortlist was co-prioritized based on patient and clinician views on acceptability, feasibility, and safety. In phase 4, ranked lists of interventions were presented by their relevance to high-income countries and low–middle-income countries.
Results
In phase 1, 43 interventions were identified, which had low uptake in practice according to 3042 professionals globally. In phase 2, a shortlist of 15 intervention domains was generated. In phase 3, interventions were deemed acceptable for more than 90 per cent of patients except for reducing general anaesthesia (84 per cent) and re-sterilization of ‘single-use’ consumables (86 per cent). In phase 4, the top three shortlisted interventions for high-income countries were: introducing recycling; reducing use of anaesthetic gases; and appropriate clinical waste processing. In phase 4, the top three shortlisted interventions for low–middle-income countries were: introducing reusable surgical devices; reducing use of consumables; and reducing the use of general anaesthesia.
Conclusion
This is a step toward environmentally sustainable operating environments with actionable interventions applicable to both high– and low–middle–income countries

Is History of Adenotonsillectomy a Protective Factor for Helicobacter pylori Gastritis?
Introduction: Helicobacter pylori is a gram-negative bacillus seen worldwide, affecting around half of the world’s population. It is reported that the adenotonsillar region is a colonisation area and plays a role in contamination. Based on this finding, there are some studies suggesting that history of previous adenotonsillectomy may be a protective factor for the colonization of H. pylori in the stomach. In this study, it was aimed to investigate whether the history of previous adenotonsillectomy was a protective factor for H. pylori gastritis. Materials and Methods: A total of 150 patients, including 75 patients with previous history of adenotonsillectomy and 75 patients without history of adenotonsillectomy, who were admitted to the gastroenterology clinic of Hitit University Corum Erol Olcok Training and Research Hospital for the first time with dyspeptic complaints and who underwent endoscopic biopsy of the antrum, were enrolled into the study. Endoscopic biopsy samples of the patients were stained histochemically with Hematoxylin Eosin (HE) and Giemsa to detect the presence of H. pylori. All cases were evaluated by the same pathologist according to the updated Sydney system. Results: The ages of the patients belonging to the group of previous history of adenotonsillectomy ranged from 22 to 80 years, with an average of 46.5 years (± 17.5 SD), and the ages of patients in the group of without history of adenotonsillectomy ranged from 24 to 75 years, with an average of 38.3 years (± 14.0 SD), and the age difference between these two groups was statistically significant. H. pylori gastritis was found in 52 (69%) of the 75 patients in the group of patients without history of adenotonsillectomy, and in 33 (44%) of the 75 patients in the group of patients with previous history of adenotonsillectomy, whose difference was statistically significant (p= 0.021). When all patients in both groups were compared, H. pylori density average was 1.6 in the group of patients without history of adenotonsillectomy, whereas H. pylori density average was 0.8 in the group of patients with previous history of adenotonsillectomy, which was statistically significant (p= 0.012). When H. pylori density in patients with H. pylori gastritis in both groups was compared, the mean value of the group of patients without history of adenotonsillectomy was 2.3, while the mean value of the group of patients with previous history of adenotonsillectomy was 1.8, which was statistically significant (p= 0.022). Conclusion: Several studies have shown that the adenotonsillar region is a colonization site for H. pylori, using different methods. In our study, adenotonsillectomy was considered to play a protective role in reducing H. pylori spread and H. pylori gastritis, as it would prevent colonization in this region
Housing sales of real estate developers in Turkey
Purpose Because of competition, residential property developers use a variety of promotional tools to gain recognition and increase their market share and the demand for housing, and to manage their customer relations. This study aims to examine what real estate developers did to detect the need for types of housing, and pricing and promoting housing. It also sought clues about how they manage customer relations in residential sales. Design/methodology/approach In this study, semi-structured interviews were conducted with real estate developers. This study has heuristic characteristics based on qualitative data. Document reviews, descriptive analysis and discourse analysis were carried out on the interview data and other sources. As purposeful sampling is generally used in qualitative studies; intensity sampling, homogeneous sampling, criterion sampling and snowball sampling were used together in this study. Findings The study found that real estate developers were inadequate at advertising and promoting, allocated little budget for promotion and did not use technology sufficiently. The real estate developers gave discounts at rates that did not actually desire, had to create payment plans, and as a result, they lost customers because they could not manage customer relations well. Research limitations/implications - Interviews were conducted with 15 real estate developers who have been selling residential properties for more than 10 years in Suleymanpasa and Corlu districts of Tekirdag. Data obtained are mostly qualitative. Originality/value This study aimed to determine real estate developers' ability to implement a variety of promotional strategies and manage customer relations. Results and conclusions can offer significant clues about real estate developers with similar characteristics. Its conclusions of this study can be compared to similar studies of real estate developers in many regions of Turkey.WOS:0005248713000012-s2.0-8508217962
