Is There Any Effect of the Physician Performing Embryo Transfer in IVF-ICSI Treatment: A Prospective Cohort Study / Existe algum efeito domédico que realiza a transferência de embriões no tratamento de FIV-ICSI: Um estudo de coorte prospectivo

Abstract Objective To evaluate whether there is an effect of the physician who transfers the embryos on pregnancy rates in in vitro fertilization-intracytoplasmic sperm injection (IVF-ICSI) treatment. Methods A total of 757 participants were analyzed between 2012 and 2017. Participants were classified according to 3 physicians who transferred the embryos: ([group 1=164 patients]; [group 2=233 patients]; [group 3=360 patients]). Baseline parameters and IVF-ICSI outcomes were compared between the groups. Results No differences were determined between the groups regarding the baseline parameters (age, age subgroups [20-29, 30-39, and ≥ 40 years old)], body mass index (BMI), smoking status, infertility period, cause of infertility, baseline follicle stimulating hormone, luteinizing hormone, estradiol (E2), thyroid stimulating hormone, prolactin levels, antral follicle count, duration of stimulation, stimulation protocol, gonadotropin dose required, maximum E2 levels, progesterone levels, endometrial thickness on human chorionic gonadotropin (hCG) administration and transfer days (p>0.05). The numbers of oocytes retrieved,metaphase II (MII), 2 pronucleus (2PN), transferred embryo, fertilization rate, day ofembryo transfer, the catheter effect and embryo transfer technique, and clinical pregnancy rates (CPRs) were also comparable between the groups (p>0.05). Conclusion Our data suggests that the physician who transfers the embryos has no impact on CPRs in patients who have undergone IVF-ICSI, but further studies with more participants are required to elucidate this situation.

Resumo Objetivo Avaliar se há ou não efeito do médico que realiza a transferência de embriões nas taxas de gravidez no tratamento com fertilização in vitro-injeção intracitoplasmática de espermatozoide (FIV-ICSI, na sigla em inglês).

Os participantes foram classificados de acordo com 3 médicos que transferiram os embriões: ([grupo 1=164 pacientes]; [grupo 2=233 pacientes]; [grupo 3=360 pacientes]). Parâmetros basais e resultados de FIV-ICSI foram comparados entre os grupos. Resultados Nenhuma diferença foi determinada entre os grupos nos parâmetros basais (idade, subgrupos de idade [20-29, 30-39 e ≥ 40 anos)], índice de massa corporal (IMC), tabagismo, período de infertilidade, causa da infertilidade, hormônio folículo estimulante basal , hormônio luteinizante, estradiol (E2), hormônio estimulador da tireoide, níveis de prolactina, contagem de folículos antrais, duração da estimulação, protocolo de estimulação, dose de gonadotrofina necessária, níveis máximos de E2, níveis de progesterona e espessura endometrial na administração de hCG e nos dias de transferência (p>0,05). O número de oócitos recuperados, MII e 2PN, embrião transferido, taxa de fertilização, dia da transferência do embrião, o efeito do cateter e a técnica de transferência de embrião e taxas clínicas de gravidez (RCPs) também foram comparáveis entre os grupos (p>0,05). Conclusão Nossos dados sugerem que o médico que transfere os embriões não tem impacto sobre as RCPs em pacientes que se submeteram a FIV-ICSI, mas mais estudos com mais participantes são necessários para elucidar esta situação.

Pulmonary effects of ozone therapy at different doses combined with antibioticotherapy in experimental sepsis model

Abstract Purpose This experimental sepsis model created with Escherichia coli aimed to investigate the histopathological effects of two different doses of ozone combined with antibiotherapy on lung tissue. Methods Rats were divided into 5 groups. Then sepsis was induced intraperitoneally in the first 4 groups. The 1st group was treated with cefepime, the 2nd and 3rd groups were treated with cefepime combined with ozone at a dose of 0.6 mg/kg and 1.1 mg/kg. Lung tissue sections were stained with hematoxylin-eosin and assessed under light microscope and scored between 0-4 in terms of histopathological findings. Results In the comparisons between Group 1 and Group 4 in terms of cellular damage (p=0.030), inflammation (p=0.000) and overall score (p=0.007), statistically significant positive effects were observed in favor of Group 1. In the comparisons of Groups 2 and 3 with Group 4, only positive effects were observed in terms of inflammation (p=0.020, p=0.012, respectively). Conclusion Although negative histopathological effects of ozone on tissue injury were detected, it was noteworthy that the increase in the ozone dose reduced the number of damaged parameters.

Assessment of Low Serum Uric Acid Level in Patients with Amyotrophic Lateral Sclerosis Evidence for Oxidative Stress

Background: The pathogenic mechanism of AmyotrophicLateral Sclerosis (ALS) remains indistinct. However, increasingevidence has indicated that uric acid (UA) may play aprotective role in the pathogenesis of ALS as well as in that ofother neurodegenerative diseases. Low serum uric acid (UA)levels are found in many neurodegenerative diseases. It hasbeen suggested that oxidative stress is one of the pathogenicmechanism for amyotrophic lateral sclerosis (ALS), and thusantioxidants such as UA that could reduce oxidative stressmight be beneficial in the early detection of progression of thedisease. The objective of this study was to prospectivelyinvestigate serum UA levels in ALS patients and to relate themto disease process and disease status.Methods: ALS patients and healthy controls who wereindividually well-matched for age, sex, and body mass index(BMI) underwent blood testing for serum UA levels, andanalyzed whether UA levels were correlated with the diseasestatus of the patients, severity of the disease as defined by theALS Functional Rating Scale-Revised (ALSFRS-R) andduration of illness.Results: The study included 37 ALS patients and 37 matchedcontrols. The serum UA level was lower in the ALS patients(4.29 mg/dl ±1.35 mg/dL, mean±SD) than in the controls (6.26mg/dL±1.22 mg/dL; p<0.001). Female ALS patients hadsignificantly lower (3.55 mg/dl± 0.89 mg/dL) than Male ALSpatients (4.53 mg/dl±1.4 mg/dL; p<0.05). Among the ALSpatients, the lower level of UA acid was strongly correlated withthe rate of disease progression (decrease in ALSFRS-R score)p<0.001. Uric acid level is inversely correlated with the durationof the disease (r -0.32). Respondents with smoking historygroup showed more likely to develop ALS than therespondents with no smoking history.Conclusion: ALS patients had lower serum UA levels than didhealthy individuals and it is significantly lower in Female ALSpatients than Male ALS patients. Uric acid levels in ALS werepositively correlated with the ALSFRS-R (severity) andnegatively associated with duration of illness. UA levels couldbe considered a biomarker of disease progression in the earlyphase in ALS patients

Relationship between seasons and pregnancy rates during intrauterine insemination. A historical cohort

ABSTRACT BACKGROUND: The underlying cause of seasonal infertility in humans is unclear, but is likely to be ­multifactorial. OBJECTIVE: The aim of our study was to compare the pregnancy rates among infertile women who underwent induced ovulation and intrauterine insemination (IUI) with the season in which the fertility treatment was performed. DESIGN AND SETTING: This retrospective cohort study was conducted on 466 patients who were treated in the reproductive endocrinology and infertility outpatient clinic of a tertiary-level women's healthcare and maternity hospital. METHODS: Retrospective demographic, hormonal and ultrasonographic data were obtained from the patients' medical records. Clomiphene citrate or gonadotropin medications were used for induced ovulation. The patients were divided into four groups according to the season (spring, winter, autumn and summer) in which fertility treatment was received. Clinical pregnancy rates were calculated and compared between these four groups. RESULTS: There were no significant differences between the seasonal groups in terms of age, infertility type, ovarian reserve tests, duration of infertility, medications used or length of stimulation. A total of 337 patients (72.3%) were treated with clomiphene citrate and 129 (27.7%) with gonadotropin; no significant difference between these two groups was observed. The clinical pregnancy rates for the spring, winter, autumn and summer groups were 15.6% (n = 24), 8.6% (n = 9), 11.5% (n = 13) and 7.4% (n = 7), respectively (P = 0.174). CONCLUSIONS: Although the spring group had the highest pregnancy rate, the rates of successful IUI did not differ significantly between the seasonal groups.

Repeatability of contrast sensitivity testing in patients with age-related macular degeneration, glaucoma, and cataract / Reprodutibilidade dos escores de sensibilidade ao contraste em pacientes com degeneração macular relacionadas à idade, glaucoma e catarata

ABSTRACT Purpose: To analyze the intrasession and intersession repeatability of contrast sensitivity (CS) measurements in patients with glaucoma, cataract, or age-related macular degeneration (AMD) and healthy controls. Methods: CS measurements were performed using the OPTEC-Functional Vision Analyzer (FVA), which uses a standardized and closed (view-in) system. Measurements for patients with glaucoma, cataract, or AMD and healthy controls were repeated within 30 minutes (intrasession) and during two sessions (intersession), separated by one week to one month. Test-retest reliability and correlation were measured using the intraclass correlation coefficient (ICC) and coefficient of repeatability (COR). Results: Ninety subjects (90 eyes) with visual acuity of 0.17 logMAR or higher in the cataract group or 0.00 logMAR in the other groups were included. During the first session, the ICC values were 0.87, 0.90, 0.76, and 0.69, and COR values were 0.24, 0.20, 0.38, and 0.25 for the control, glaucoma, cataract, and AMD groups, respectively. The reliability scores significantly improved during the second session, except in the glaucoma group. There was an acceptable floor effect and no ceiling effect at higher frequencies in the glaucoma and AMD groups. Conclusion: In subjects with good visual acuity, the FVA system is useful for evaluating CS and demonstrates good repeatability, as shown by ICC and COR. Because there is no ceiling effect, this system is beneficial for evaluation of early changes in CS, particularly in patients with glaucoma or AMD.

RESUMO Objetivo: Analisar a reprodutibilidade intrassessão e intersessão das medidas de sensibilidade ao contraste (CS) em pacientes com degeneração macular relacionada à idade (AMD), glaucoma e catarata. Método: As medidas de CS foram feitas pelo OPTEC-Funcional Visão Analyzer (FVA), que utiliza um sistema padronizado e fechado de avaliação da acuidade visual. Medidas em pacientes com AMD, glaucoma, catarata e nos controles saudáveis foram repetidas no prazo de 30 minutos (intrassessão) em duas visitas (intersessão), separadas por uma semana a um mês. A confiabilidade e correlação teste-reteste foram calculados por meio do coeficiente de correlação intraclasse (ICC) e coeficiente de reprodutibilidade (COR). Resultados: Noventa olhos de 90 indivíduos foram recrutados com acuidade visual de 0,17 logMAR ou melhor em catarata e 0,00 logMAR nos outros grupos. A confiabilidade da CS na primeira visita dos grupos normal, glaucoma, catarata e AMD foram, respectivamente, ICC 0,87; 0,90; 0,76; 0,69, e COR 0,24; 0,20; 0,38; 0,25. Os índices de confiabilidade foram significativamente melhorados nas segundas visitas, exceto no grupo glaucoma. Houve um efeito chão aceitável e nenhum efeito teto em frequências mais altas nos grupos glaucoma e AMD. Conclusões: Em indivíduos com boa acuidade visual, o sistema FVA de avaliação da CS é útil e apresenta boa confiabilidade, como mostrado pelas análises de ICC e COR. Por não apresentar efeito teto, este sistema parece ser benéfico para a avaliação das alterações precoces de CS, especialmente no glaucoma e AMD.

Effects of Trimetazidine on T Wave Alternans in Stable Coronary Artery Disease

BACKGROUND AND OBJECTIVES: Studies reveal that the microvolt T wave alternans (MTWA) test has a high negative predictive value for arrhythmic mortality among patients with ischemic or non-ischemic cardiomyopathy. In this study, we investigate the effects of trimetazidine treatment on MTWA and several echocardiographic parameters in patients with stable coronary artery disease. SUBJECTS AND METHODS: One hundred patients (23 females, mean age 55.6±9.2 years) with stable ischemic heart disease were included in the study group. Twenty-five age- and sex-matched patients with stable coronary artery disease formed the control group. All patients were stable with medical treatment, and had no active complaints. Trimetazidine, 60 mg/day, was added to their current treatment for a minimum three months in the study group and the control group received no additional treatment. Pre- and post-treatment MTWA values were measured by 24 hour Holter testing. Left ventricular systolic and diastolic functions were assessed by echocardiography. RESULTS: After trimetazidine treatment, several echocardiographic parameters related with diastolic dysfunction significantly improved. MTWA has been found to be significantly improved after trimethazidine treatment (63±8 µV vs. 53±7 µV, p<0.001). Abnormal MTWA was present in 29 and 11 patients pre- and post-treatment, respectively (p< 0.001). CONCLUSION: Trimetazidine improves MTWA, a non-invasive determinant of electrical instability. Moreover, several echocardiographic parameters related with left ventricular functions also improved. Thus, we can conclude that trimetazidine may be an effective agent to prevent arrhythmic complications and improve myocardial functions in patients with stable coronary artery disease.

Sensitivity and specificity of strain and strain rate imaging [measured by speckle tracking] in assessment of ischemic heart disease compared to dobutamine stress echocardiography

Background: speckle tracking echocardiography [STE] enables objective assessment of left ventricular [LV] function through analysis of myocardial strain and strain rate. This study aims to determine the sensitivity and specificity of global longitudinal strain [GLS] and global longitudinal strain rate [GLSR] of LV in assessment of myocardial Jirnction compared to peak wall motion score index [WMSI] at dobutamine stress echocardiography [DSE]

Methods: fifty patients with suspected or known myocardial ischemia were evaluated by conventional echocardiography, DSE, STE and coronary angiography [CA]. Standard apical views were wed to calculate GLS and GHR by STE. WMSI was calculated at peak stress during DSE. Significant coronary lesion[s] were indicated by >/= 50% luminal stenosis in CA

Results: GLS and GLSR were significantly lower in patients with significant CAD than those with

Conclusion: GLS and GLSR are negatively correlated to peak WMSI. Both deformation parameters can predict significant lesion[s] in CA, but with lower diagnostic accuracy than DSE

Cisternostomy for management of intracranial hypertension in severe traumatic brain injury; case report and literature review

Main goal in the management of patients with severe traumatic brain injury [TBI] is control of intracranial pressure [ICP]. Decompressive craniectomy is an accepted technique for control of refractory intracranial hypertension in patients with severe TBI. Because of high complication rate after decompressive craniectomy, new techniques such as basal cisternostomy have developed. We herein report a case of severe TBI in a 13-year-old boy treated by cisternostomy. The patient was admitted following a motor vehicle accident. Brain CT scan showed diffuse brain edema, left frontal contusion and posterior interhemispheric subdural hematoma. The patient underwent ICP monitoring. Subsequently, with 26 mmHg mean-value of ICP, he was treated surgically by cisternostomy technique. A progressive improvement of the neurological conditions in the following hours. After 5 days the boy was discharged and in the 3-months follow-up he was completely recovered. Cisternostomy could be an appropriate alternative to decompressive craniectomy for management of intracranial hypertension in patietns with sever TBI

Preventing nerve damage during total thyroidectomy or total lobectomy surgeries

Background and objective: Thyroidectomy is an operation that involves surgical removal of all or part of the thyroid gland. The main postoperative complications of thyroidectomy are hypoparathyroidism and recurrent laryngeal nerve injury. This study aimed to find out the main postoperative complications particularly nerve damage during total thyroidectomy or total lobectomy

Methods: The medical records of patients who were diagnosed with thyroid disease and underwent surgery between January 2[nd], 2013 and December 30[th], 2014 in Teaching, Shar, Soma and Zhian hospitals in Sulaimaniyah were retrospectively reviewed

Results: All patients who underwent total thyroidectomy or total lobectomy surgeries were discharged within 24 hours of the operation. During the average follow-up of 24 months, no case of permanent recurrent laryngeal nerve injury was registered. Vocal cord paralysis was considered to be present, when there was absent or markedly reduced movement of the affected vocal cord

Conclusions: Meticulous hemostasis and a delicate technique are required to prevent nerve injury. We recommend dissection and division of all the vessels flush with the thyroid capsule at the anterior and peripheral aspect of the gland. Separate ligation of anterior and posterior branched of the superior thyroid artery will preserve the external branch of the superior laryngeal nerves

THE PREVALENCE OF CELIAC DISEASE IN PATIENTS WITH IRON-DEFICIENCY ANEMIA IN CENTER AND SOUTH AREA OF IRAN

Background - Celiac disease is an immune-mediated enteropathy due to a permanent sensitivity to gluten in genetically susceptible people. Iron-deficiency anemia is the most widely experienced anemia in humans. Iron-deficiency anemia additionally is a common extra intestinal manifestation of celiac disease. Objective - To investigate correlation between tTg levels and histological alterations and then to determine the prevalence of celiac disease in Center and South area patients of Iran with iron deficiency anemia. Methods - A total of 402 patients aged 12-78 years who presented with iron-deficiency anemia were included in this study. Hemoglobin, mean corpuscular volume and serum ferritin were determined. Venous blood samples for anti-tissue transglutaminase antibody immunoglobuline A and G were obtained from these patients. Upper gastrointestinal endoscopy was recommended to patients who had positive serology. Results - Of 402 patients with iron-deficiency anemia, 42 (10.4%) had positive serology for celiac disease. The small intestine biopsy of all patients with positive serology showed pathological changes (Marsh I, II & III). There was not significant difference in the mean hemoglobin level between iron-deficiency anemia patients with celiac disease and without celiac disease, duodenal biopsy results did not show significant relationship between the severity of pathological changes and levels of anti-tTG IgG (P -value: 0/869) but significant relationship was discovered between pathological changes and levels of anti-tTG IgA (P -value: 0/004). Conclusion - Screening of celiac disease by anti-tissue transglutaminase antibody should be completed as a routine investigation in patients with iron-deficiency anemia. Also physicians must consider celiac disease as a possible reason of anemia in all patients with iron deficiency anemia.

Contexto - A doença celíaca é uma enteropatia imunomediada, devido a uma sensibilidade permanente ao glúten em pessoas geneticamente suscetíveis. A anemia por deficiência de ferro é a anemia mais frequente em seres humanos e, além disso, é uma manifestação extra intestinal comum da doença celíaca. Objetivo - Investigar a correlação entre níveis de imunoglobulina de anticorpos anti-transglutaminase tissular A (anti-tTG IgA) e G (IgG anti-tTG) e alterações histológicas e, em seguida, determinar a prevalência de doença celíaca no Centro e Sul do Irã em pacientes com anemia por deficiência de ferro. Métodos - Foram incluídos neste estudo um total de 402 pacientes com idades entre 12-78 anos, que apresentavam anemia por deficiência de ferro. Hemoglobina, volume corpuscular médio e ferritina sérica foram determinados. Amostras de sangue venoso para imunoglobulina de anti-tTG IgA e IgG anti-tTG foram obtidas nestes pacientes. Endoscopia gastrointestinal foi recomendada para pacientes que tiveram sorologia positiva. Resultados - Dos 402 pacientes com anemia por deficiência de ferro, 42 (10,4%) tiveram sorologia positiva para doença celíaca. A biópsia do intestino delgado de todos os pacientes com sorologia positiva mostrou alterações patológicas (Marsh I, II e III). Não houve diferença significativa no nível de hemoglobina média entre os pacientes com deficiência de ferro com ou sem a doença celíaca. O resultado da biopsia duodenal não mostrou relação significativa entre a gravidade das alterações patológicas e níveis de IgG anti-tTG (P -valor: 0/869), mas descobriu-se relação significativa entre as alterações patológicas e níveis de anti-tTG IgA (P -valor: 0/004). Conclusão - A pesquisa de doença celíaca por dosagem de anticorpo anti-transglutaminase tissular deve ser completada como investigação de rotina em pacientes com anemia por deficiência de ferro. Os clínicos devem considerar a doença celíaca como um possível causa de anemia em todos os pacientes com anemia ferropriva.

ABSTRACTBACKGROUND AND OBJECTIVES:Tenoxicam is widely used in osteoarthritis treatment and we aimedto compare the effectivity of oral and intra-articular administration of tenoxicam in osteoarthri-tis treatment.METHODS: This study was performed between 2011 and 2012 by retrospectively analyzing andcomparing the findings of 60 patients who were clinically and radiologically diagnosed with kneedegenerative osteoarthritis in Bünyan state hospital pain policlinic. 60 patients included in thestudy were divided into two groups. The first group (tenoxicam IA, n = 30) included patientfindings of those subjected to intra-articular injection of 20 mg tenoxicam to the knee oncea week for three weeks and the second group (oral tenoxicam, n = 30) included patients whowere administered 20 mg oral tenoxicam once a day for three weeks. All patients were clini-cally evaluated pre-treatment and in the 1st week, 1st month and 3rd month post-treatmentaccording to specified criteria.RESULTS AND CONCLUSIONS: Twenty two of 60 patients included in the study were male and 38were female. In both groups significant improvements were detected in all of the observedparameters: visual analog scale, Western Ontario McMaster Osteoarthritis Index (pain, physicalactivity, knee stiffness) and Lequesne index scores and in the evaluations performed in 1st week,1st month and 3rd month with respect to pre-treatment values. Besides, a better complianceto treatment and gastrointestinal system tolerability in tenoxicam IA group was also observed.Intra-articular tenoxicam administration could be thought as an alternative treatment methodin patients with knee osteoarthritis who cannot use oral tenoxicam especially due to systemicgastrointestinal system side effects and those who have difficulties in adapting to treatment.

RESUMOJUSTIFICATIVA E OBJETIVOS: Tenoxicam é amplamente usado no tratamento da osteoartrite (OA)e o nosso objetivo foi comparar a eficácia de tenoxicam administrado por via oral (VO) e intra-articular (IA) no tratamento da OA.MÉTODOS: Este estudo foi conduzido entre 2011 e 2012 por meio de análise retrospectiva ecomparação dos resultados de 60 pacientes que foram clínica e radiologicamente diagnosticadoscom OA degenerativa de joelhos na Policlínica de Tratamento da Dor do Hospital Estadual deBünyan. Os 60 pacientes incluídos no estudo foram alocados em dois grupos. O primeiro grupo(tenoxicam IA, n = 30) incluiu resultados de pacientes submetidos à injeção nos joelhos porvia IA de 20 mg de tenoxicam uma vez por semana durante três semanas e o segundo grupo(tenoxicam VO, n = 30) incluiu pacientes que receberam 20 mg de tenoxicam por VO uma vezpor dia durante três semanas. Todos os pacientes foram avaliados clinicamente na fase basalpré-tratamento e em uma semana, um mês e três meses pós-tratamento, de acordo com oscritérios especificados.RESULTADOS E CONCLUSÕES: Dos 60 pacientes, 22 eram do sexo masculino e 38 do sexo feminino.Em ambos os grupos, melhorias significativas foram detectadas em todos os parâmetros da escalavisual analógica, do índice Western Ontario and MacMaster (Womac --- dor, atividade física erigidez dos joelhos) e do índice de Lequesne nas avaliações feitas em uma semana, um mês etrês meses e comparadas aos valores basais. Além disso, uma melhor adesão ao tratamento etolerabilidade ao sistema gastrointestinal no grupo tenoxicam IA também foram observadas. Aadministração de tenoxicam IA pode ser considerada como um método opcional de tratamentoem pacientes com OA de joelhos que não podem usar tenoxicam por VO, especialmente porcausa dos efeitos colaterais sobre o sistema gastrintestinal, e naqueles com dificuldades de adaptação ao tratamento.

Quercetin protects the retina by reducing apoptosis due to ischemia-reperfusion injury in a rat model / Quercetina protege a retina reduzindo a apoptose consequente à lesão por isquemia e reperfusão em um modelo de rato

Purpose: This study aimed to investigate the effect of quercetin on apoptotic cell death induced by ischemia-reperfusion (I/R) injury in the rat retina. Methods: Twenty-four rats were divided into four equal groups: control, ischemic, solvent, and quercetin. I/R injury was achieved by elevating the intraocular pressure above the perfusion pressure. Intraperitoneal injections of 20 mg/kg of quercetin and dimethyl sulfoxide (DMSO) were performed in the quercetin and solvent groups, respectively, immediately prior to I/R injury, and the researchers allowed for the retinas to be reperfused. Forty-eight hours after injury, the thicknesses of the retinal ganglion cell layer (RGCL), inner nuclear layer (INL), inner plexiform layer (IPL), outer plexiform layer (OPL), and outer nuclear layer (ONL) were measured in all groups. Moreover, the numbers of terminal deoxynucleotidyl transferase dUTP nick-end-labeled [TUNEL (+)] cells and caspase-3 (+) cells in both INL and ONL were evaluated in all groups. Results: The administration of quercetin was found to reduce the thinning of all retinal layers. The mean thickness of INL in the quercetin and ischemic groups was 21 ± 5.6 µm and 16 ± 6.4 µm, respectively (P<0.05). Similarly, the mean thickness of ONL in the quercetin and ischemic groups was 50 ± 12.8 µm and 40 ± 8.7 µm, respectively (P<0.05). The antiapoptotic effect of quercetin in terms of reducing the numbers of both TUNEL (+) cells and caspase-3 (+) cells was significant in INL. The mean number of TUNEL (+) cells in INL in the ischemic and quercetin groups was 476.8 ± 45.6/mm2 and 238.72 ± 251/mm2, respectively (P<0.005). The mean number of caspase-3 (+) cells in INL of ischemic and quercetin groups was 633.6 ± 38.7/mm2 and 342.4 ± 36.1/mm2, respectively (P<0.001). Conclusion: The use of quercetin may be beneficial in the treatment of retinal I/R injury because of its antiapoptotic effect on the retinal layers, particularly in INL. .

Objetivo: O objetivo deste estudo é investigar o efeito da quercetina, contra a morte celular por apoptose induzida por lesão consequente à isquemia-reperfusão (I/R) na retina de ratos. Método: Vinte e quatro ratos foram divididos em quatro grupos iguais: controle, isquêmico, solvente e quercetina. O modelo lesão por I/R foi realizado por meio da elevação da pressão intraocular acima da pressão de perfusão, em todos os grupos. Injecções intraperitoneais de 20 mg/kg de quercetina ou sulfóxido de dimetilo (DMSO) foram realizadas nos grupos quercetina e solvente, respectivamente, imediatamente antes da lesão por I/R, permitindo que as retinas fossem reperfundidas. Quarenta e oito horas após a lesão, as espessuras de camada de células ganglionares da retina (RGCL), camada nuclear interna (INL), camada plexiforme interna (IPL), camada plexiforme externa (OPL), e a camada nuclear externa (ONL) foram medidas em todos os grupos. Além disso, o número de células TUNEL (+) e caspase-3 (+) tanto na camada nuclear interna quanto na camada nuclear externa foi avaliada em todos os grupos. Resultados: A administração de quercetina diminuiu o afinamento de todas as camadas da retina em comparação com o grupo isquêmico. A espessura média da camada nuclear interna nos grupos quercetina e isquêmico foi de 21 ± 5,6 µm e 16 ± 6,4 µm, respectivamente (p<0,05). A espessura média da camada nuclear externa no grupo quercetina e isquêmico foi 50 ± 12,8 µm e 40 ± 8,7 µm, respectivamente (p<0,05). O efeito anti-apoptótico de quercetina em termos de redução do número de células TUNEL (+) e caspase-3 (+) foi significativa na INL. O número médio de células TUNEL (+) da camada nuclear interna no grupo isquêmico e quercetina foi 476,8 ± 45,6/mm2 e 238,72 ± 251/mm2, respectivamente (p<0,005). O médio número de células de caspase-3 (+) na INL do grupo isquêmico e quercetina foi 633,6 ± 38,7/mm2 e 342,4 ± 36,1/mm2, respectivamente (p<0,001). Conclusão: A utilização ...

Changes in retinal nerve fiber layer thickness after spinal surgery in the prone position: a prospective study / Alterações da espessura da camada de fibras nervosas da retina após cirurgia da coluna vertebral em pronação: estudo prospectivo / Alteraciones del espesor de la capa de fibras nerviosas de la retina después de la cirugía de la columna vertebral en pronación: estudio prospectivo

BACKGROUND AND OBJECTIVES: Changes in ocular perfusion play an important role in the pathogenesis of ischemic optic neuropathy. Ocular perfusion pressure is equal to mean arterial pressure minus intraocular pressure. The aim of this study was to evaluate the changes in the intraocular pressure and the retinal nerve fiber layer thickness in patients undergoing spinal surgery in the prone position. METHODS: This prospective study included 30 patients undergoing spinal surgery. Retinal nerve fiber layer thickness were measured one day before and after the surgery by using optical coherence tomography. Intraocular pressure was measured by tonopen six times at different position and time-duration: supine position (baseline); 10 min after intubation (Supine 1); 10 (Prone 1), 60 (Prone 2), 120 (Prone 3) min after prone position; and just after postoperative supine position (Supine 2). RESULTS: Our study involved 10 male and 20 female patients with the median age of 57 years. When postoperative retinal nerve fiber layer thickness measurements were compared with preoperative values, a statistically significant thinning was observed in inferior and nasal quadrants (p = 0.009 and p = 0.003, respectively). We observed a statistically significant intraocular pressure decrease in Supine 1 and an increase in both Prone 2 and Prone 3 when compared to the baseline. Mean arterial pressure and ocular perfusion pressure were found to be significantly lower in Prone 1, Prone 2 and Prone 3, when compared with the baseline. CONCLUSIONS: Our study has shown increase in intraocular pressure during spinal surgery in prone position. A statistically significant retinal nerve fiber layer thickness thinning was seen in inferior and nasal quadrants one day after the spinal surgery. .

JUSTIFICATIVA E OBJETIVOS: As alterações de perfusão ocular desempenham um papel importante na patogênese da neuropatia óptica isquêmica. A pressão de perfusão ocular é igual à pressão arterial média menos a pressão intraocular. O objetivo deste estudo foi avaliar as alterações da pressão intraocular e da espessura da camada de fibras nervosas da retina em pacientes submetidos à cirurgia da coluna vertebral em pronação. MÉTODOS: Este estudo prospectivo incluiu 30 pacientes submetidos à cirurgia da coluna vertebral. A espessura da camada de fibras nervosas da retina foi medida um dia antes e um depois da cirurgia, com o uso da tomografia de coerência óptica. A pressão intraocular foi medida seis vezes com o Tonopen e o tempo de duração em posições diferentes: em supinação (basal), 10 minutos após a intubação (Supinação 1); após a pronação aos 10 minutos (Pronação 1), 60 minutos (Pronação 2) e 120 minutos (Pronação 3) e logo após a supinação no período pós-operatório (Supinação 2). RESULTADOS: Nosso estudo envolveu 10 pacientes do sexo masculino e 20 do feminino, com média de 57 anos. No pós-operatório, quando as medidas da espessura da camada de fibras nervosas da retina foram comparadas com os valores do pré-operatório, um afinamento estatisticamente significativo da retina foi observado nos quadrantes nasais e inferiores (p = 0,009 e p = 0,003, respectivamente). Observamos uma diminuição da pressão intraocular estatisticamente significante em Supinação 1 e um aumento em ambos momentos Pronação 2 e Pronação 3, em comparação com os valores basais.

Effects of smoking on venous cannulation pain: a randomized prospective trial / Efeitos do tabagismo sobre a dor durante o cateterismo venoso: um estudo prospectivo e randomizado / Efectos del tabaquismo sobre el dolor durante el cateterismo venoso: un estudio prospectivo y aleatorizado

BACKGROUND AND OBJECTIVES: It has been demonstrated that smoking increases pain perception; however the effect of smoking on perception of pain during venous cannulation is not known. The purpose of this study is to determine whether or not smoking has an effect on pain perception due to peripheral venous cannulation. METHODS: 220 patients scheduled to have elective surgery were enrolled in the study and were divided into two groups (Group S and C, n = 110 for each) according to their smoking habits. Numerical rating scale was introduced to the patients and then peripheral venous cannulation at the dorsum of the hand was made with a 20 G intracath. Pain perception of the patients was scored by subsequent numerical rating scale questioning. RESULTS: The demographic characteristics of the groups were identical. Numerical rating scale scores in Group S and C were 3.31 ± 1.56 and 1.65 ± 1.23, respectively (p < 0.001). CONCLUSION: Pain perception due to peripheral venous cannulation is higher in smokers. Future studies on pain treatment should consider the smoking habits of patients. .

The investigation of airway management capacity of v-gel and cobra-PLA in anaesthetised rabbits

PURPOSE: To evaluate the applicability and airway management capacity of v-gel(r) and Cobra PLA in rabbit anaesthesia during assisted (AV) or controlled ventilation (CV). METHODS: This study was carried out in 44 adult New Zealand white rabbit. Baseline arterial pH, PaCO2 and PaO2 values were recorded. Anaesthesia was induced with 5 mg/kg xylasine and 35 mg/kg ketamine HCI combination. AV rabbits were assigned as; control (CG-AV; n=5), LMA (LMA-AV; n=5), cobra PLA (PLA-AV; n=5) and v-gel (v-gelAV; n=5). Rabbits have CV were also assigned as; ET (ET-CV; n=6), LMA (LMA-CV; n=6), cobraPLA (PLA-CV; n=6) and v-gel (v-gelCV; n=6). All measurements were repeated 1st, 5th, 15th and 30th mins during anaesthesia. RESULTS: The less insertion time, number of attempt and complications are recorded in v-gel applied rabbits compared to other apparatus. For arterial pH values significant differences are recorded in especially at 15th and 30th min between groups of CV (p<0.005 or p<0.001). All groups had similar results with each other during anaesthesia for PaCO2 except for LMA-CV group. CONCLUSION: The v-gel may be used as airway device in rabbit anaesthesia undergoing AV or CV and also can be a suitable alternative to endotracheal tubes and laryngeal mask airway. .

A Novel Echocardiographic Method for Assessing Arterial Stiffness in Obstructive Sleep Apnea Syndrome

BACKGROUND AND OBJECTIVES: Obstructive sleep apnea syndrome (OSAS) is associated with increased arterial stiffness and cardiovascular complications. The objective of this study was to assess whether the color M-mode-derived propagation velocity of the descending thoracic aorta (aortic velocity propagation, AVP) was an echocardiographic marker for arterial stiffness in OSAS. SUBJECTS AND METHODS: The study population included 116 patients with OSAS and 90 age and gender-matched control subjects. The patients with OSAS were categorized according to their apnea hypopnea index (AHI) as follows: mild to moderate degree (AHI 5-30) and severe degree (AHI> or =30). Aortofemoral pulse wave velocity (PWV), carotid intima-media thickness (CIMT), brachial artery flow-mediated dilatation (FMD), and AVP were measured to assess arterial stiffness. RESULTS: AVP and FMD were significantly decreased in patients with OSAS compared to controls (p<0.001). PWV and CIMT were increased in the OSAS group compared to controls (p<0.001). Moreover, AVP and FMD were significantly decreased in the severe OSAS group compared to the mild to moderate OSAS group (p<0.001). PWV and CIMT were significantly increased in the severe group compared to the mild to moderate group (p<0.001). AVP was significantly positively correlated with FMD (r=0.564, p<0.001). However, it was found to be significantly inversely related to PWV (r=-0.580, p<0.001) and CIMT (r=-0.251, p<0.001). CONCLUSION: The measurement of AVP is a novel and practical echocardiographic method, which may be used to identify arterial stiffness in OSAS.
