Correlation of integrated pulmonary index with clinical observation in unilateral and bilateral spinal anaesthesia in geriatric patients

Background: In present study, we aimed to determine the role of integrated pulmonary index (IPI) in monitorising geriatric cases that have spontaneous ventilation under unilateral and spinal block during partial hip prosthesis and total knee arthroplasty.Methods: 24 patients who were over 65 years of age and with ASA I-IV, femoral neck fracture, intertrochanteric fracture and in whom gonarthros had developed were simply randomised into two groups. Values of blood pressure, pulse rate (PR), SPO2, EtCO2, respiratory rate (RR), IPI were recorded. Unilateral spinal block was administered with 7.5 mg, 0.5% bupivacaine and 25 mcg fentanyl in Group I and with 12.5 mg 0.5% bupivacaine and 25 mcg fentanyl in Group II. Values were recorded in intervals of 5 and 15 minutes and continued to be recorded from the moment of cement application. Preoperative mask ventilation or intubation need was recorded.Results: For EtCO2, bilateral spinal block scores at post-cement 15 minutes; postop 5 minutes were found to be high providing that they were within the clinically normal limits compared to the unilateral scores. A correlation between IPI and SpO2, EtCO2, respiratory rate, pulse rate was identified. In both groups, IPI was found to be in normal range and a correlation was identified through clinical observation.Conclusions: IPI might be the sole numerical value in early identification of clinical correlation and respiratory failure. For the IPI monitor is small and easy to be handled along with its screen that shows many parameters together makes the device be easily used

Presence of Class I and Class II Integrons in Methicilin Resistant Staphylococci and Their Relations with Antibiotic Resistance: A Preliminary Study from Turkey

Background: Emergence of antibiotic resistance is a major public health concern. It is known that antibiotic resistance is transferred by different ways. Integrons as one of these mechanisims cause to spread antibiotic resistance in Gram negative bacteria but also it is shown to be effective for transferring genes in Gram positive bacteria. In the present study we aimed to examine the prevalence of class I and class II integrons in MRSA and MRCNS strains isolated from patients and to determine the relationship between antibiotic resistance and the presence of integrons. Methods: Sixty four MRSA and 62 MRCNS strains were included in this study. Antibiotic susceptibility testings were performed. Genomic and plasmid DNAs were extracted and Polymerase Chain Reaction (PCR) was used for the detection of the intI and intII genes. The PCR products were visualised in 1.5 % agarose gel electrophoresis. Pearson chi-square test and Fisher’s exact test were used for comparing categorical variables. Results: Among 126 staphylococci 11 (8.7% - 4 MRSA and 7 MRCNS) were shown to carry class I integron; whereas 7 MRCNS (5.5%) were class II positive. Both of class I and class II integrons were detected to possess in four MRSA (3.2%). There was no statistically significant relation between presence of integrons and resistance to each of antibiotics (p>0.05). Conclusion & Recommendation: In the present study we did not find any significant relation between resistance rates and the presence of integrons but we suggest that these results showed an important data about the extended distributions of integrons not only among Gram negative bacteria but also in staphylococci.Keywords: MRSA, MRCNS, class I integron, class II integron, anbiotic resistanceDOI: 10.7176/JHMN/75-0

Ulusaldan Küresele: Popülizm, Demokrasi, Güvenlik Konferansı

Öngörülmesi giderek güçleşen, sarsıntılı ve savrulmalı zamanlardan geçiyoruz. İkinci Dünya Savaşı ve Soğuk Savaş ortak deneyimleri sonrasında 1950’lerden ve 1990’lardan itibaren demokratik sistemlerin peş peşe dalgalarla meşrulaşacağı, yaygınlaşacağı ve güçleneceği öngörüsü hakimdi. Ancak son yıllarda yaşanan bazı gelişmelerle demokrasilerin geleceği tekrar sorgulanmaya başladı. Gerek 11 Eylül ile başlayan ve IŞİD ile devam eden ve şiddet içeren İslamcı radikalizm, gerek Batı demokrasilerinde popülist radikal sağ hareketlerin ve beyaz ırkçı grupların yükselişi ve iktidara gelişi, bir yandan güvenlik-özgürlük ikileminin demokrasi dengesini bozdu, bir yandan da hem demokratik sistemlerin hem dünya barışının geleceğini bizi tekrar sorgular, sorgulatır hale getirdi. Demokrasileri bildiğimizi zannediyoruz, ama demokrasiler ile ilgili daha öğrenmemiz gereken çok şey var. Demokrasi kaderimiz de geleceğimiz de olmak zorunda değil belki de. Ya da belki yanlış yerden soru sormaya başlıyoruz, belki demokrasi yerine yeni bir referansa ihtiyacımız var. Aslında demokrasileri çantada keklik görmeyip, sabırla büyütüp yeşertmek, geliştirmek, korumak, ileri safhalara taşımak ve bizden sonraki nesillere aktarmak bir sorumluluk, ve bu sorumluluk bizlere ait. Popülizm, demokrasi, güvenlik kavramlarının her biri bugün sıkça ve yaygın olarak kullandığımız kavramlar olarak gündelik sohbetlerimizin içine kadar girmiş durumda. Bu yaygın kullanımlarına rağmen her bir kavram, üzerine düşünmeye, tartışmaya ve değerlendirmeye tekrar tekrar olanak verecek derinlikte. Her bir tartışma bir diğerini açarken, farklı gibi görünen bu kavramların birbirleriyle kesiştikleri zeminler bulmak mümkün. Popülist liderlerin politikaları bütün siyaset yapma biçimlerini kendine çeken ya da kendinden uzaklaştıran eksenler yaratarak her ikisini de aynı anda besleyebiliyor. Popülist politikaya angaje olan liderler ve grupların yanında bu politikaya karşı mücadele eden kişiler ve kitleler de yok değil, ancak kimi zaman bu kitleler eleştirdiği bu siyaset biçiminin kurucu öznesi haline de gelebiliyor. Bunun karşısında tabandan gelen demokratikleşme talepleri ve popülist siyasetle beraber kurumsallaşan diğer politika yapma biçimleri, demokrasi anlayışımızı farklı yönlere çekebiliyor. Bu demokratikleşme talepleri kimi zaman olumlu karşılıklar alsa da, kimi zaman devletlerin güvenlik politikaları ile etkisizleştirilmeye ve bastırılmaya çalışılıyor. Güvenlik politikalarının alanı günümüz teknolojisi sebebiyle o kadar genişledi ki, bu politikanın nesnesi haline gelmemiş varlık ve alan bulmak neredeyse mümkün değil. Ulusaldan Küresele: Popülizm, Demokrasi, Güvenlik konferansımız bu alanların kendine özgülüklerini göz önünde bulundururken, aralarındaki kesişimleri de ortaya koyan pek çok değerli sunuma ev sahipliği yaptı. Konferansın düzenlenmesinde emeği geçen herkese, ve bu bildiri kitabında tam metinleri ve özetleri bulunan bütün katılımcılarımıza çok teşekkür ederiz.Publisher's Versio

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

Study of Venturia inaequalis sensitivity to fungicides through molecular and biological methodologies

This study was aimed to correlate the results of relative germination from in vitro tests by trifloxystrobin with those of qPCR on a wide range of V. inaequalis populations and monoconidial isolates. Samples were collected in Italian and Turkish distinct locations from orchards with different scab management. In this study, an allele-specific qPCR with primer sets designed was successfully developed to quantitatively determine the frequency of QoI-resistant allele G143A in populations and monoconidial isolates of V. inaequalis. qPCR followed a similar pattern to that obtained using in vitro conidial germination test in very sensitive and very resistant populations. However, the variability between two test results was observed in hetereogenous populations. Therefore, the results of correlations between in vitro and qPCR showed a positive but not very high correlation for Venturia inaequalis populations (R2=0.70). On the contrary, this correlation between two assessment methods was very high for monoconidial isolates (R2=0.92). Results obtained in quantitative PCR and from traditional spore germination assay differed for the same fungal population and in some cases, it is difficult to assess the resistance in the field by only qPCR. It was concluded that it is not always possible to correlate the frequency of detection of the mutation with biological assessment. In such situations, monitoring by molecular techniques must be supported by standard in vitro resistance assessments and observation of field performance in order to have correct conclusions

Gut Microbiome Alteration after Reboxetine Administration in Type-1 Diabetic Rats

Antidepressants are drugs commonly used in clinical settings. However, there are very limited studies on the effects of these drugs on the gut microbiota. Herein, we evaluated the effect of reboxetine (RBX), a selective norepinephrine (noradrenaline) reuptake inhibitor (NRI), on gut microbiota in both diabetic and non-diabetic rats. This is the first report of relation between reboxetine use and the gut microbiota to our knowledge. In this study, type-1 diabetes induced by using streptozotocin (STZ) and RBX was administered to diabetic rats and healthy controls for 14 days. At the end of the treatment, stool samples were collected. Following DNA extraction, amplicon libraries for the V3-V4 region were prepared and sequenced with the Illumina Miseq platform. QIIME was used for preprocessing and analysis of the data. As a result, RBX had a significant effect on gut microbiota structure and composition in diabetic and healthy rats. For example, RBX exposure had a pronounced microbial signature in both groups, with a low Firmicutes/Bacteroidetes ratio and low Lactobacillus levels. While another abundance phylum after exposure to RBX was Proteabacteria, other notable taxa in the diabetic group included Flavobacterium, Desulfovibrionaceae, Helicobacteriaceae, Campylobacterales, and Pasteurellacae when compared to the untreated group
