New description of vagal nerve commanted intrapancreatic taste buds and blood glucose level: An experimental analysis
Introduction: There have been thousands of neurochemical mechanism about blood glucose level regulation, but intrapancreatic taste buds and their roles in blood glucose level has not been described. We aimed to investigate if there are taste buds cored neural networks in the pancreas, and there is any relationship between blood glucose levels. Methods: This examination was done on 32 chosen rats with their glucose levels. Animals are divided into owned blood glucose levels. If mean glucose levels were equal to 105 ± 10 mg/dL accepted as euglycemic (G-I; n = 14), 142 ± 18 mg/dL values accepted as hyperglycemic (G-II; n = 9) and 89 ± 9 mg/dL accepted as hypoglycemic (G-III; n = 9). After the experiment, animals were sacrificed under general anesthesia. Their pancreatic tissues were examined histological methods and numbers of newly described taste bud networks analyzed by Stereological methods. Results compared with Mann-Whitney U test P < 0.005 considered as significant. Results: The mean normal blood glucose level (mg/dL) and taste bud network densities of per cm3 were: 105 ± 10 mg/dL; 156±21 in G-I; 142 ± 18 mg/dL and 95 ± 14 in G-II and 89 ± 9 mg/dL and 232 ± 34 in G-III. P values as follows: P < 0.001 of G-II/G-I; P < 0.005 of G-III/G-I and P < 0.0001 of G-III/G-II. We detected periarterial located taste buds like cell clusters and peripherally located ganglia connected with Langerhans cells via thin nerve fibers. There was an inverse relationship between the number of taste buds networks and blood glucose level. Conclusion: Newly described intrapancreatic taste buds may have an important role in the regulation of blood glucose level
Safety and efficacy of Amplatzer duct occluder II and konar-MF™ VSD occluder in the closure of perimembranous ventricular septal defects in children weighing less than 10 kg
IntroductionDevice closure of perimembranous ventricular septal defects (pmVSD) is a successful off-label treatment alternative. We aim to report and compare the outcomes of pmVSD closure in children weighing less than 10 kg using Amplatzer Duct Occluder II (ADOII) and Konar-MF VSD Occluder (MFO) devices.MethodsRetrospective clinical data review of 52 children with hemodynamically significant pmVSD, and sent for transcatheter closure using ADOII and MFO, between January 2018 and January 2023. Baseline, procedural, and follow-up data were compared according to the implanted deviceResultsADOII devices were implanted in 22 children with a median age of 11 months (IQR, 4.1–14.7) and weight of 7.4 kg (IQR, 2.7–9.7). MFO devices were implanted in 30 children with a median age of 11 months (IQR, 4.8–16.6) and weight of 8 kg (IQR, 4.1–9.6). ADOII were implanted (retrograde, 68.1%) in defects with a median left ventricular diameter of 4.6 mm (IQR, 3.8–5.7) and right ventricular diameter of 3.5 mm (IQR, 3.1–4.9) while MFO were implanted (antegrade, 63.3%) in defects with a median left ventricular diameter of 7 mm (IQR, 5.2–11.3) (p > 0.05) and right ventricular diameter of 5 mm (IQR, 2.0, 3.5–6.2) (p < 0.05). The procedural and fluoroscopy times were shorter with the MFO device (p < 0.05). On a median follow-up of 41.2 months (IQR, 19.7–49.3), valvular insufficiency was not observed. One 13-month-old child (6.3 kg) with ADOII developed a complete atrioventricular heart block (CAVB) six months postoperative and required pacemaker implantation. One 11-month-old child (5.9 kg) with MFO developed a CAVB 3 days postoperative and the device was removed. At 6 months post-procedure, only one child with MFO still experiences a minor residual shunt. There was one arterio-venous fistula that resolved spontaneously.ConclusionBoth the MFO and ADOII are effective closure devices in appropriately selected pmVSDs. CAVB can occur with both devices. The MFO is inherently advantageous for defects larger than 6 mm and subaortic rims smaller than 3 mm. In the literature, our series represents the first study comparing the mid-term outcomes of MFO and ADOII devices in children weighing less than 10 kg
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
The relationship between serum NT-proBNP levels and severity of coronary artery disease assessed by SYNTAX score in patients with acute myocardial infarction
WOS: 000504050500015PubMed: 31648513Background/aim: In the present study, we aimed to investigate the relationship between NT-proBNP and SYNTAX score, which is a measure of the complexity of coronary artery disease. Materials and methods: We enrolled 405 consecutive patients with myocardial infarction who underwent coronary angiographic examination. Patients were divided into 3 groups according to their SYNTAX scores. Those with SYNTAX score = 33 were included in the high SYNTAX score group (HSTX). Results: NT-proBNP levels were found to be significantly higher in the HSTX group compared to the other groups (P < 0.001) and in the ISTX group compared to the LSTX group (P < 0.001). The NT-proBNP levels demonstrated an increase from low SYNTAX score to high SYNTAX score tertiles. Conclusions: NT-ProBNP levels in patients with myocardial infarction on admission were independently associated with extent, severity, and complexity of coronary atherosclerosis as assessed by SYNTAX score
The Relationship Between Serum Fibrinogen Level and Stent Restenosis in Patients with Acute Coronary Syndrome
Amaç: İn-stent restenoz, koroner arterlere stent implantasyonu sonrası stentli bölgenin aşamalı olarak yeniden daralmasıdır. İlaç salınımlı stentlerin kullanılmaya başlanmasıyla restenoz oranları azalmış olsa da hala majör problem olmaya devam etmektedir. Bu çalışmada akut koroner sendrom nedeniyle koroner anjiyografi yapılan hastalarda in-stent restenozu ile fibrinojen düzeyi arasındaki ilişkiyi araştırmayı amaçladık. Gereç ve Yöntemler: İki grup arasında yaş, hipertansiyon, diyabetes mellitus, sigara içimi ve sol ventrikül ejeksiyon fraksiyonu açısından fark yoktu (p>0.005, hepsi için). İSR grubunda erkek cinsiyet ve hiperlipidemi oranı İSR olmayan gruba göre daha yüksekti (sırasıyla, p=0.04; 0.007). Biyokimyasal parametrelerden homosistein ve fibrinojen dışında iki grup arasında fark izlenmedi. Serum homosistein ve fibrinojen seviyesi İSR olan grupta İSR olmayan gruba göre istatistiksel olarak anlamlı derecede yüksek saptandı (sırasıyla, p=0.009; 0.032). Dislipidemi, homosistein ve fibrinojen İSR'nin bağımsız prediktörleri olarak saptandı. Bulgular: Tedavi sonrası WOMAC ağrı, WOMAC tutukluk, WOMAC fonksiyonel durum ve WOMAC toplam skorlarında tedavi öncesi değerlere göre her iki grupta da istatistiksel olarak anlamlı gelişme saptandı (p0.005, for all). Male gender and hyperlipidemia rate were higher in ISR group than non-ISR group (p=0.04; 0.007 respectively). Biochemical parameters were not different between the groups except for homocysteine and fibrinogen. Serum homocysteine and fibrinogen levels were significantly higher in the ISR group than in the non-ISR group (p=0.009; 0.032 respectively). Dyslipidemia, homocysteine and fibrinogen were identified as independent predictors of ISR. Conclusion: Plasma fibrinogen levels may be an important biochemical parameter in predicting the risk of restenosis in patients with bare metal stents implanted for coronary artery disease

Akut Koroner Sendromlu Hastalarda Çok Damar Hastalığı ile Kardiyovasküler Risk Faktörleri Arasındaki İlişki
Amaç: Akut koroner sendrom olgularında ciddi darlık olan koroner arter sayısı ile kardiyovasküler risk faktörleri arasındaki ilişki değerlendirildi. Yöntemler: Bu çalışma retrospektif olarak dizayn edildi. 2016–2018 tarihleri arasında akut koroner sendrom sebebiyle koroner anjiografi yapılan 904 hasta çalışmaya dahil edildi. Ciddi koroner arter darlığı olmayan ve koroner operasyon geçiren hastalar çalışma dışı bırakıldı. Hastalar kritik koroner arter darlıklarına göre tek damar hastalığı (TDH) ve çok damar hastalığı (ÇDH) olacak şekilde iki gruba ayrıldı. ÇDH ile TDH olanlar klasik kardiyovasküler risk faktörleri açısından karşılaştırıldı. Bulgular: Hastaların 544’ünde (%60) ÇDH 365’inde (%40) TDH saptandı. ÇDH olan grupta yaş, hipertansiyon ve diyabet mellitus istatistiksel olarak daha fazla saptandı (sırasıyla p<0.001, p=0.003, p=0.005). TDH olan grupta ise erkek cinsiyet, aile öyküsü ve sigara içiciliği istatistiksel olarak daha fazla saptandı (sırasıyla p=0.006, p<0.001, p<0.001). Sonuç: Diyabet ve hipertansiyon ÇDH grubunda yüksek saptanırken aile öyküsü ve sigara içiciliği TDH grubunda yüksek saptandı. Akut koroner sendrom hastalarında bu risk faktörlerin göz önünde bulundurulması önemlidir.Aim: The relationship between the number of coronary arteries with severe stenosis and cardiovascular risk factors was evaluated in patients with acute coronary syndrome. Material-Method: This study was designed retrospectively. 904 patients who underwent coronary angiography for acute coronary syndrome between 2016–2018 were included in the study. Patients who underwent coronary bypass surgery and didn’t have severe coronary artery disease were excluded. The patients were divided into two groups according to critical coronary artery stenosis as single vessel disease and multiple vessel disease. The relationship between multivessel disease and risk factors was compared. Results: Multivessel disease was detected in 544 (60%) patients and single vessel disease in 365 (40%) patients. Age, hypertension and diabetes were found to be higher in multivessel disease (respectively p<0.001, p=0.003, p=0.005). Male gender, family history and smoking were found to be higher in the single vessel disease. Conclusion: Diabetes and hypertension were higher in multivessel disease group, while family history and smoking were higher in single vessel disease group. It is important to consider these risk factors in patients with acute coronary syndrome
