The association between glycemia and clinical outcomes in patients with diabetes mellitus and pulmonary thromboembolism

ABSTRACT Objective: Various studies have shown that diabetes mellitus (DM) increases the risk of thrombosis in the venous system as well as in the arterial system. In this study, it was aimed to evaluate the association between admission blood glucose levels and clinical severity, recurrence, and mortality in pulmonary embolism in patients with DM. Materials and methods: This study was designed as a retrospective cross-sectional study. Patients with DM who were admitted to a tertiary care hospital due to pulmonary embolism (PE) between 2014 and 2019 were included. Demographic characteristics, radiological findings, clinical class of embolism, and mortality data were retrieved from hospital records. Patients with and without recurrent disease, as well as patients who survived and died, were compared. Also, patients were classified according to quartiles of admission blood glucose levels. The quartiles were compared in terms of mortality, clinical, class, and recurrence. Results: Two hundred ninety-three patients with DM and PE were included in the study. Patients with adverse outcome had significantly higher admission blood glucose levels (respectively, 197.9 ± 96.30 mg/dL vs. 170.7 ± 74.26 mg/dL; p = 0.03). Patients in the third and fourth quartile of admission blood glucose levels (>152 mg/dL) had significantly more severe disease with a higher proportion of massive and sub-massive PE and higher pro-BNP levels (respectively, p = 0.01 and 0.02). Conclusion: Non-survived patients and recurrent disease were associated with higher admission blood glucose levels. Also, patients with admission blood glucose levels higher than 152 mg/dL tend to have clinically more severe diseases.

Visual or computer-based measurements: Which is important for the interpretation of an athlete's electrocardiography?

SUMMARY OBJECTIVE: Preparticipation screening of athletes by electrocardiography is the most crucial step in determining sudden cardiac death risk factors. Several electrocardiography interpretation software programs have been developed for physicians practicing in this field. Our study aimed to assess cardiopoint sudden death screening module by comparing its findings with two cardiologists using Seattle and International criteria. METHODS: A total of 303 licensed national athletes (37% females) were enrolled. electrocardiographies were examined by the cardiopoint sudden death screening module using Seattle criteria and cardiologists. The consistency between cardiologists and software was compared, and the confidence assessment of the module was tested. RESULTS: With regard to Seattle criteria, moderate consistency was found between the cardiopoint sudden death screening module and the 1st (κ=0.41) and 2nd cardiologist (κ=0.59). Consistency between two cardiologists was moderate (κ=0.55). When we applied International criteria, there was moderate consistency between the module and the 1st cardiologist (κ=0.42), and good consistency between the module and the 2nd cardiologist (κ=0.63). Consistency between the two cardiologists was good (κ=0.62). CONCLUSION: The cardiopoint sudden death screening module had similar agreement with cardiologists based on both criteria. However, the software needs to be updated according to International criteria. Using computer-based measurements for preparticipation screening will help to save time and provide standardization of electrocardiography interpretation.

Should we reconsider high-risk features in thyroid ultrasonography?

SUMMARY OBJECTIVE: Round shape is generally considered to reduce the risk of malignancy according to recent guidelines. On the contrary, according to some reports, spherically shaped thyroid nodules are associated with a higher risk of malignancy. Thus, we aimed to evaluate the malignancy risk of solid round isoechoic nodules detected at thyroid ultrasonography and compare it with that of solid ovoid isoechoic nodules. METHODS: Between 2017 and 2022, solitary solid round isoechoic nodules with diameters ³10 and £25 mm at thyroid ultrasonography were retrospectively selected and enrolled in the study. Age, size, nodule volume, serum thyrotropin levels, thyroid antibody levels, and cytopathological and histopathological results were recorded. RESULTS: A total of 457 solitary solid isoechoechoic nodules from 457 patients (262 females and 195 males; median age, 59 [31-70] years) were selected, of which 203 were solid round isoechoic nodules, and 254 were solid ovoid isoechoic nodules. A total of 54 surgical operations were performed on 457 nodules, and 31 of them resulted in malignancy. From the 31 malignant results, 25 originated from solid round isoechoic nodules and the remaining 6 originated from solid ovoid isoechoic nodules (p<0.025). CONCLUSION: We found that round nodules have higher malignancy rates than ovoid nodules. We think that ultrasonographic risk stratification systems used to target the most suitable nodules for the necessary biopsies can be dynamically updated, and sphericity can be added as a parameter in patient-based decision-making.

Surgical treatment of acromioclavicular dislocation: hook plate versus suture button / Tratamento cirúrgico da luxação acromioclavicular: laca de gancho versus botão de sutura

ABSTRACT Objectives: We aimed to compare the functional and radiographical outcomes of reconstruction of acute unstable acromioclavicular joint (ACJ) dislocation using Hook Plate (HP) versus Suture Endobutton (SE) fixation techniques. Methods: Forty-six consecutive patients with grade III to V ACJ dislocation according to Rockwood classification who underwent either HP or SE fixation in the period between January 2017 and June 2020 were evaluated. The treatment modalities were divided into either HP or SE fixation. The radiological assessment included standard anterior-posterior (AP) views to evaluate coracoclavicular (CC) distances for vertical reduction. Results: CC distances were grouped as preoperative (CC1), early postoperative (CC2), and late postoperative (CC3). The distance variance between CC2 and CC3 was referred as ΔCC (CC3 - CC2). A statistically significant difference was found in ΔCC between the two groups (p=0.008). ΔCC was significantly higher in the SE group compared to the HP group (p<0.05). The Constant and UCLA Scores of patients in the SE group were found to be significantly higher than in the HP group patients. Conclusion: Clinical outcomes were more satisfactory in patients with acute unstable ACJ dislocation who underwent SE compared to HP procedures, at the end of the first year. Evidence Level IV; Case Series.

RESUMO Objetivo: Nosso objetivo foi comparar os resultados funcionais e radiográficos da reconstrução da luxação instável aguda da articulação acromioclavicular (ACJ) utilizando técnicas de fixação com placa com gancho (HP) versus botão de sutura (SE). Métodos: 46 pacientes com luxação da ACJ de grau III a V, de acordo com a classificação de Rockwood, que foram submetidos à fixação com HP ou SE no período de janeiro de 2017 a junho de 2020, foram avaliados. As modalidades de tratamento foram divididas em fixação HP ou SE. Na avaliação radiológica, foi utilizada a incidência antero-posterior (AP) para avaliação da redução vertical, por meio da medida da distância córaco-clavicular (CC). Resultados: As distâncias CC foram agrupadas em pré-operatória (CC1), pós-operatória imediata (CC2) e pós-operatória tardia (CC3). A variação da distância entre (CC2) e (CC3) foi denominada ΔCC. Uma diferença estatisticamente significativa foi encontrada na ΔCC entre os dois grupos (p=0,008). O ΔCC foi significativamente maior no grupo SE em comparação com o grupo HP (p <0.05). As pontuações de Constant e UCLA dos pacientes do grupo SE foram significativamente mais elevadas do que as dos pacientes do grupo HP. Conclusão: Os resultados clínicos foram mais satisfatórios com a técnica SE em comparação com a HP ao final do primeiro ano. Nível de Evidência IV; Série de casos.

Tepid Modified Del Nido Cardioplegia in Adults Undergoing Cardiac Surgery: A Propensity-Matched Analysis

Abstract Introduction: Del Nido cardioplegia was reported to provide adequate myocardial protection and clinical outcomes with improved surgical flow in adult cardiac surgical procedures. And many clinicians have already modified the traditional formula. This study aims to investigate the efficacy and safety of tepid modified del Nido cardioplegia compared to cold blood cardioplegia in adult patients undergoing cardiac surgery. Methods: This retrospective study included one hundred consecutive adult patients undergoing cardiac surgical procedures using tepid modified del Nido cardioplegia. One hundred consecutive adult patients undergoing cardiac surgical procedures with cold blood cardioplegia were the control group. Propensity score matching yielded 89 modified del Nido and 89 cold blood cardioplegia patients. Results: There were no significant differences when comparing the two matched groups regarding the requirement for intraoperative defibrillation (P=0.36), postoperative peak troponin T levels (0.18), perioperative inotropic support (P=0.26), intra-aortic balloon pump requirement (P=0.62), and postoperative left ventricular ejection fraction at discharge (P=0.4) and on the sixth postoperative month (P=0.37). Mean cross-clamping time (P=0.005), cardiopulmonary bypass time (P=0.03), and total operation time (P=0.03) were significantly shorter in the del Nido group. Conclusion: Tepid modified del Nido cardioplegia may be a safe alternative to cold blood cardioplegia in adult patients undergoing cardiac surgical procedures.

The Relationship Between Mitral Annular Calcification and Controlling Nutritional Status Score

ABSTRACT Introduction: The relationship between mitral annular calcification (MAC) and the controlling nutritional status (CONUT) score has not been previously studied. In this study, we investigated the relationship between MAC and CONUT score to evaluate the nutritional status of patients with MAC. Methods: A total of 275 patients, including 150 patients with MAC and 125 patients without MAC, who presented to a cardiology outpatient clinic were enrolled in the study. Results: There was no difference in the CONUT score between the two groups. Correlation analysis indicated that CONUT score was positively correlated with left atrial (LA) diameter (r=0.190, P=0.020) and interventricular septum thickness (r=0.179, P=0.028) in the MAC+ group. In multivariate regression analysis, only LA diameter (odds ratio 95% confidence interval = 1,054-1,189, P=0.0001) was independently associated with MAC. Conclusion: The present study investigated the relationship between CONUT score and MAC for the first time in the literature. We demonstrated that CONUT score was not significantly higher in patients with MAC without chronic diseases. However, CONUT score was correlated with LA diameter in patients with MAC. We therefore conclude that, for patients admitted with MAC and high LA diameter, CONUT is a valuable nutritional and inflammatory status index.

Prevalence of chondromalacia patella according to patella type and patellofemoral geometry: a retrospective study

Abstract BACKGROUND: The relationships between the morphometric structure of the patellofemoral joint, patella type and chondromalacia patella are still a matter of debate. OBJECTIVE: To identify the prevalence of chondromalacia patella by determining the patella type and making patellofemoral morphometric measurements. DESIGN AND SETTING: Retrospective cohort study in an orthopedics and traumatology clinic in Turkey, conducted between June 2017 and November 2019. METHODS: This study involved 562 knees of 522 patients with anterior knee pain (246 males and 316 females; mean age 46.59 years). The patients were grouped according to presence of chondromalacia patella (group I) or absence of chondromalacia patella (group II). The patella type, lateral trochlear inclination, medial trochlear inclination, trochlear angle, sulcus angle, patellar tilt and Insall-Salvati index were assessed. Group comparisons were made using chi-square tests or Student t tests. The r value was used to determine the magnitude of relationships between pairs of variables. RESULTS: Among the 562 knees evaluated, 265 (50.71%) presented type I patella, 195 (36.7%) type II, 100 (12.3%) type III and 2 (0.3%) type IV. Group I consisted of 448 knees and group II consisted of 114 knees. Significant differences were found between the groups in terms of age, gender, patella type and lateral inclination angles (P < 0.05). CONCLUSION: Detecting the patella type and making lateral inclination measurements in patients with anterior knee pain are of great importance for diagnosing suspected chondromalacia patella, particularly in the early degenerative period.

Comparison of anesthesia management in transcatheter aortic valve implantation: a retrospective cohort study

Abstract Background and objectives We aimed to investigate the effects of two different anesthetic techniques in our patients who underwent transcatheter aortic valve implantation (TAVI). Methods In this study, 303 patients who underwent TAVI procedure with a diagnosis of severe aortic stenosis between January 1, 2012 and December 31, 2018 were retrospectively evaluated. The patients were divided according to the type of anesthesia given during each procedure as; general anesthesia (GA), local anesthesia (LA). Results LA was preferred in 245 (80.8%) of 303 patients who underwent TAVI, while GA was preferred in 58 patients (19.1%). Median ages ​​of our patients who received LA and GA were 83 and 84, respectively. The procedure and anesthesia durations of the patients in the GA group were longer than the LA group (p< 0.00001, p< 0.00001, respectively). Demographic and pre-operative clinical data were similar in comparison between two groups (p> 0.05) except for peripheral artery disease. Hypertension was the most common comorbidity in both groups. While the number of inotrope use was significantly higher in patients who received GA (p< 0.00001), no significant differences were found between LA and GA patients in terms of major complications and mortality (p> 0.05). Intensive care and hospital stays were significantly shorter in the LA group (p= 0.001, p= 0.023, respectively). Conclusion The anesthetic technique of TAVI procedure did not have a significant effect on outcomes including; complications, mortality and success of the procedure. LA provides shorter duration of procedure and hospital stay.

Propensity-Matched Analysis of Del Nido Cardioplegia in Adults Undergoing Cardiac Surgery with Prolonged Cross-Clamping Time

Abstract Introduction: There is not enough data in the literature regarding the safety and efficiency of del Nido cardioplegia in patients with prolonged cross-clamping time. This study aims to determine the efficacy and safety of del Nido cardioplegia compared to cold blood cardioplegia in patients with prolonged aortic cross-clamping time. Methods: In this retrospective study, patients with an aortic cross-clamping time ≥ 90 minutes were included. One hundred consecutive adult patients undergoing cardiac surgery using del Nido cardioplegia comprised the study group, and 100 consecutive adult patients undergoing cardiac surgical procedures using cold blood cardioplegia comprised the control group. Propensity score matching yielded 88 del Nido cardioplegia and 88 cold blood cardioplegia patients. Results: There were no significant differences when comparing the matched groups regarding the requirement for intraoperative defibrillation, postoperative peak troponin T levels, inotropic support, intra-aortic balloon pump requirement, and left ventricular ejection fraction at discharge and on the sixth postoperative month; also, there were no significant differences when comparing cardiopulmonary bypass time and total operation time. Mean cross-clamping time was significantly shorter in the del Nido group (P<0.001). Conclusion: Del Nido cardioplegia may be a safe alternative to cold blood cardioplegia in adults undergoing cardiac surgical procedures with prolonged aortic cross-clamping time.

Systemic immune-inflammation index as a novel predictor of atrial fibrillation after off-pump coronary artery bypass grafting

SUMMARY OBJECTIVE: This study aims to examine the predictive role of systemic immune-inflammation index on postoperative new-onset atrial fibrillation in patients undergoing off-pump coronary artery bypass grafting. METHODS: A total of 722 patients undergoing elective off-pump coronary artery bypass grafting between January 2017 and September 2021 were included in this study and divided into two groups as the atrial fibrillation group (n=172) and the non-atrial fibrillation group (n=550). Both groups were compared in terms of patients' baseline clinical features, operative and postoperative variables, and preoperative hematological indices derived from the complete blood count analysis. Multivariate logistic regression and receiver-operating characteristic curve analyses were performed to detect the independent predictors of postoperative new-onset atrial fibrillation. RESULTS: The median age and length of hospital stay in the atrial fibrillation group were significantly higher than those in the non-atrial fibrillation group. The median values of white blood cell, platelet, neutrophil, neutrophil/lymphocyte ratio, platelet/lymphocyte ratio, and systemic immune-inflammation in the atrial fibrillation group were significantly greater than in those in the non- atrial fibrillation group. Logistic regression analysis demonstrated that age, platelet, platelet/lymphocyte ratio, and systemic immune-inflammation were independent predictors of postoperative new-onset atrial fibrillation. receiver-operating characteristic curve analysis revealed that systemic immune-inflammation of 706.7×103/mm3 constituted cut-off value to predict the occurrence of new-onset atrial fibrillation with 86.6% sensitivity and 29.3% specificity. CONCLUSION: Our study revealed for the first time that systemic immune-inflammation predicted new-onset atrial fibrillation after off-pump coronary artery bypass grafting.

Retinal microvascular changes in patients with familial mediterranean fever: a study based on optical coherence tomography angiography / Alterações microvasculares da retina em pacientes com febre mediterrânea familiar: estudo baseado em angiotomografia de coerência óptica

ABSTRACT Purpose: In this study, we aimed to show whether a difference exists between retinal and choroidal microcirculation findings between patients with familial Mediterranean fever and healthy controls. Methods: Thirty-two patients with familial Mediterranean fever and 30 healthy controls were included in the study. All the patients underwent a complete ophthalmologic examination, including best-corrected visual acuity and intraocular pressure measurement. The AngioVue optical coherence tomography angiography device (Optovue, Fremont, CA) with split-spectrum amplitude-decorrelation angiography was used to evaluate and examine the retinal microvascular structure. Three-dimensional en face Optical coherence tomography angiography images were obtained by examining the macula using the 3 x 3 mm scanning protocol in the Angio Retina mode and the optic nerve using the 3 x 3 mm scanning protocol in the Angio Disk mode. All the patients' right eyes were examined. Results: A total of 62 subjects were included in the study, of whom 32 (53.3%) were female and 30 (46.7%) were male. No statistically significant difference was found between the two groups in terms of optic nerve head or radial peripapillary capillary vessel density. On examination, the superficial capillary plexuses were statistically similar between the two groups, but the deep capillary plexus vessel density in the parafovea, superior hemi, temporal, and superior areas were significantly lower in the patients with familial Mediterranean fever. Conclusions: We found that the capillary plexus vessel density was significantly lower in the parafovea, superior hemi, temporal, and superior regions in the patients with familial Mediterranean fever than in the control group. Therefore, OCTA, a noninvasive study, may be useful for understanding the systemic effects of familial Mediterranean fever.

RESUMO Objetivos: Este estudo teve como objetivo mostrar se há diferença entre os achados da microcirculação retiniana e coroidal entre pacientes com febre mediterrânica familiar e um grupo controle saudável. Métodos: Trinta e dois pacientes com febre mediterrânica familiar e 30 controles saudáveis foram incluídos neste estudo. Todos os pacientes foram submetidos a um exame oftalmológico completo, incluindo a acuidade visual melhor corrigida e medida da pressão intraocular. O aparelho AngioVue Optical coherence tomography angiography (Optovue, Fremont, CA) com angiografia de correlação de amplitude de espectro dividido foi utilizado para avaliar e examinar a estrutura microvascular da retina. As angiotomografias de coerência ópticas en face tridimensionais foram obtidas examinando o protocolo de varredura macular 3 x 3 mm (modo angio retina) e o nervo óptico com o protocolo de varredura 3 x 3 mm (modo angio-disco). Todos os olhos direitos dos pacientes foram examinados. Resultados: Foram incluídos neste estudo, 62 sujeitos, dos quais 32 (53,3%) eram do sexo feminino e 30 (46,7%) do sexo masculino. Não houve diferença estatisticamente significativa entre os dois grupos quanto à densidade dos vasos da cabeça do nervo óptico ou da densidade dos vasos capilares peripapilares radiais. Durante o exame, os plexos capilares superficiais foram estatisticamente semelhantes entre esses dois grupos, mas a densidade profunda dos vasos do plexo capilar nas areas parafovea, hemi superior, temporal e superior foram significativamente menores nos pacientes com febre mediterrânica familiar. Conclusões: Verificamos que a densidade dos vasos do plexo capilar foi significativamente menor nas regiões parafovea, hemi superior, temporal e superior em pacientes com febre mediterrânica familiar em comparação com o grupo controle. Portanto, pode ser útil usar a angiotomografia de coerência óptica, por tratar-se de um estudo não invasivo, para melhor compreensão dos efeitos sistêmicos da febre mediterrânica familiar.

Endoscopic endonasal dacryocystorhinostomy learning curve / Curva de aprendizagem de dacriocistorrinostomia endonasal endoscópica

ABSTRACT Purpose: To compare the learning curves of the specialists in two different fields without previous endoscopic endonasal dacryocystorhinostomy experience as well as to reveal the related complications with surgical success rates. Methods: We retrospectively investigated 90 patients who received consecutive endoscopic endonasal dacryocystorhinostomy with mucosa preservation by an ophthalmologist (Group 1, n=45) and an otorhinolaryngologist (Group 2, n=45) between October 2017 and October 2019. Patients who were admitted with epiphora complaints and diagnosed with primary acquired nasolacrimal duct obstruction through lacrimal irrigation test and aged >18 years with at least 6 months of follow-up were included in the study. In all cases, additional pathologies such as septum deviation were evaluated by performing maxillofacial imaging. Patients' medical records were evaluated in terms of surgery duration, complications, and functional achievements. Results: The mean surgical duration of the patients in Group-2 was 36.27 ± 11.61 min, while it was 43.62 ± 16.89 min in Group-1; the difference was statistically significant (p=0.018). Functional achievements in Group 1 was 84.4% (73.3% in the first set of 15 cases, 93.3% in the last set of 15 cases) in Group 2; this rate was 88.9% (80% in the first set of 15 cases, 93.3% in the last set of 15 cases), and the difference was not statistically significant (p=0.53). Septum intervention in addition to endoscopic surgery in both the groups (p=0.03, p=0.005, respectively) and intense bleeding during surgery (for both the groups, p<0.0001) significantly decreased the functional success. Conclusion: Endoscopic endonasal dacryocystorhinostomy, performed after the necessary training, can provide high success and low complication rates when even conducted by ophthalmologists who are unfamiliar with endoscopic surgery after an experience of 30 cases.

RESUMO Objetivos: O objetivo deste estudo é comparar as curvas de aprendizagem dos especialistas em dois campos diferentes sem experiência prévia de dacriocistorrinostomia endonasal endoscópica e revelar as complicações com as taxas de sucesso cirúrgico. Métodos: Foram investigados retrospectivamente 90 pacientes que receberam dacriocistorrinostomia endonasal endoscópica consecutiva com preservação da mucosa realizada por um oftalmologista (Grupo 1, n=45) e realizada por um otorrinolaringologista (Grupo 2, n=45) entre outubro de 2017 e outubro de 2019. Foram incluídos no estudo pacientes admitidos com epífora e diagnosticados com obstrução primária do ducto nasolacrimal adquirido como resultado do teste de irrigação lacrimal, com idade superior a 18 anos e com, pelo menos, 6 meses de acompanhamento. Em todos os casos, patologias adicionais, como o desvio do septo, foram avaliadas por meio da realização de imagens maxilofaciais. Os prontuários dos pacientes foram avaliados quanto à duração da cirurgia, complicações e desempenho funcional. Resultados: A média de duração cirúrgica dos pacientes no Grupo-2 foi de 36,27 ± 11,61 minutos, enquanto no Grupo-1 foi de 43,62 ± 16,89 minutos, sendo a diferença estatisticamente significativa (p=0,018). O desempenho funcional no Grupo 1 foi de 84,4% (73,3% nos primeiros 15 casos, 93,3% nos últimos 15 casos) no Grupo 2, essa taxa foi de 88,9% (80% nos primeiros 15 casos, 93,3% nos últimos 15 casos) e a diferença não foi estatisticamente significativa (p=0,53). A intervenção do septo além da cirurgia endoscópica em ambos os grupos (p=0,03, p=0,005, respectivamente) e sangramento intenso durante a cirurgia (para ambos os grupos, p<0,0001) diminuiu significativamente o sucesso funcional. Conclusão: A dacriocistorrinostomia endonasal endoscópica, realizada após o treinamento necessário, pode ser realizada com alto sucesso e com baixas taxas de complicações por oftalmologistas que não estão familiarizados com a cirurgia endoscópica após adquirirem experiência com trinta casos.

Evaluation of macular and peripapillary vascular parameter change in healthy subjects after caffeine intake using optical coherence tomography angiography

Purpose: To observe the effects of caffeine intake on vessel densities in macular and peripapillary regions and to analyze the correlations of vascular properties of these two interlinked regions in healthy volunteers using optical coherence tomography angiography (OCTA). Methods: In this prospective randomized, double?masked, placebo?controlled study, 120 participants were grouped into two groups: sixty subjects as a study group, which received caffeine and sixty subjects as a placebo group, which received a placebo. OCTA imaging was performed at baseline and 1 h after drug intake. Changes in macular and radial peripapillary capillary (RPC) vessel densities (VD) and foveal avascular zone (FAZ) parameters and correlation of these parameters were analyzed. Results: Baseline macular and RPC VD and FAZ parameters showed no significant difference between study and placebo groups (P > 0.05 for all). VD parameters in all segments of superficial and deep macular regions and peripapillary region showed a statistically significant decrease after caffeine intake (P < 0.001 for all). All macular superficial VD parameters showed a positive correlation with deep perifovea VD (P < 0.05 for all). Also, superficial perifovea VD was positively correlated with all deep macular VD parameters except deep fovea VD (P < 0.05 for all). Conclusion: We show that caffeine causes a decrease in macular and peripapillary vessel densities in healthy subjects, and correlations were observed between macular and peripapillary VD parameters. We believe that future studies are needed to support the effect of caffeine on peripapillary VD and the idea of using deep perifovea VD as the main parameter to estimate superficial macular parameters.

Retrospective analysis on efficacy of convalescent plasma in acute respiratory distress syndrome due to COVID-19

ABSTRACT BACKGROUND: Coronavirus disease 2019 (COVID-19) is an ongoing global health threat. However, currently, no standard therapy has been approved for the disease. OBJECTIVES: To evaluate the clinical effectiveness of convalescent plasma (CP) in patients with acute respiratory distress syndrome (ARDS) due to COVID-19. DESIGN AND SETTING: Retrospective study conducted at Kayseri City Education and Research Hospital, Kayseri, Turkey. METHODS: The case group consisted of adult patients (> 18 years) with ARDS due to COVID-19 who received CP in combination with antiviral and supportive treatment. These patients were compared with others who only received antiviral and supportive treatment. RESULTS: During the study period, a total of 30 patients with ARDS due to COVID-19 were included. Eleven patients (36%) received CP in combination with antiviral and supportive treatment, whereas nineteen patients (64%) in the control group only received antiviral and supportive treatment. On admission, the median age, demographic and clinical data and initial laboratory test results were similar between the groups (P > 0.05). On the 14th day of treatment, the laboratory values remained similar between the groups (P > 0.05). The mortality rates were not significantly different between the groups. CONCLUSION: CP treatment did not affect mortality or lead to clinical improvement for COVID-19 patients with ARDS.

Does pulmonary hypertension affect early-term outcomes of off-pump coronary artery bypass surgery?

SUMMARY OBJECTIVE: This study aimed to investigate the effect of preoperative pulmonary hypertension (PHT) on postoperative early mortality and morbidity in patients undergoing off-pump coronary artery bypass grafting (CABG). METHODS: A total of 1107 patients undergoing elective first-time off-pump CABG between January 2011 and April 2022 were included in this retrospective observational cohort study. The patients were categorized into two groups according to their preoperative systolic pulmonary artery pressure (SPAP) values. The PHT group (n=104) consisted of patients with a SPAP value >30 mmHg, while the non-PHT group (n=1003) consisted of patients with a SPAP value ≤30 mmHg. Patients' preoperative demographics and clinical features, operative data, and postoperative outcomes were recorded and then compared between the groups. RESULTS: In the PHT group, the median age was significantly higher (66 vs. 63 years, p=0.001) and the median left ventricular ejection fraction level was significantly lower (45 vs. 50%, p=0.045) as compared to the non-PHT group. Additionally, the PHT group included a significantly greater percentage of patients with chronic obstructive pulmonary disease (22.1 vs. 7.4%, p=0.019). As perioperative early-term outcomes, complications, and mortality were considered, the groups were statistically similar, and there were no significant differences between the groups, except for the development of atrial fibrillation. CONCLUSION: For the first time in the literature, this study revealed that mild PHT (mean SPAP=38.9±8.7 mmHg) did not significantly affect early-term outcomes of off-pump CABG.

Online challenges that emerge as a public health issue for adolescents: Assessment of psychiatric comorbidity and the importance of parenting

ABSTRACT Background: Online Challenge is neither an application nor an internet-based game; instead, users receive a link to it via chat groups on social media. Our aim is to identify the potential differences between the normal population and youth drawn to online challenges. These potential differences are the examining the parenting skills of parents of children who participate in the challenges and determining underlying psychopathologies through structured clinical interviews. Method: A questionnaire-based cross-sectional study was used to obtain further in-depth information on the comorbid psychopathology of children who play the BWC and on the parenting skills. The Development and Well Being Assessment and Alabama Parenting Questionnaire was applied to the children and their families in both the control and case groups. Results: Two groups of children and parents were recruited: a clinical sample (case) group (n = 34) and a community sample (control) group (n = 141). Attention-deficit/hyperactivity disorder (ADHD), oppositional defiant disorder (ODD), specific phobia and CD (conduct disorder) were significantly more frequent in the clinical sample than in the community sample. The median scores for the Alabama Parenting Questionnaire (APQ) parental involvement, positive parenting, and poor monitoring/supervision subscales were significantly lower in the clinical sample than in the community sample. Conclusion: As far as we know, this study is the first to examine comorbid psychopathologies of online challenge-style games and parenting skills. We believe that as research into these subject increases, it will assist mental health professionals to develop prevention strategies and to manage cases resulting from the Blue Whale Challenge (BWC) and other online challenges that pose a serious threat to mental health and that have driven many young people to suicide worldwide.

The evaluation of psychogenic non-epileptic seizures (PNES) cases with saline injection method in video-EEG monitorization unit / Avaliação de casos de crises não epilépticas psicogênicas (CNEPs) pelo método de injeção de solução salina em unidade de monitoramento por vídeo-EEG

ABSTRACT Background: It has been reported that 10 to 30% of patients sent to epilepsy centers with a diagnosis of refractory epilepsy are diagnosed with psychogenic non-epileptic seizure (PNES). A wide variety of provocative methods are used to assist PNES diagnosis. Objective: To investigate the effect of seizure induction on the diagnosis and prognosis of PNES. Methods: We retrospectively examined 91 patients with PNES complaints in our video-EEG laboratory. Intravenous saline was administered to all patients for induction of seizures. Results: Saline injection was performed in 91 patients referred to our EEG lab with PNES initial diagnosis, 57 of whom were female and 34 male. Saline injection triggered an attack in 82 patients (90%). Conclusions: In this study we have concluded that provocative methods are practical, cheap and, most of all, effective for patient diagnosis. In clinical practice, explaining the diagnosis is the first and most important step of the treatment, and careful patient-doctor communication has a positive impact on patient prognosis.

RESUMO Antecedentes: Há relatos de que 10 a 30% dos pacientes com epilepsia refratária enviados a centros de epilepsia são diagnosticados com crise não epiléptica psicogênica (CNEP). Uma ampla variedade de métodos provocativos é usada para auxiliar no diagnóstico de CNEP. Objetivo: Investigar o efeito da indução de convulsões no diagnóstico e no prognóstico de CNEP. Métodos: Examinamos 91 pacientes com queixas de CNEP em nosso laboratório de vídeo-EEG. Foi administrada solução salina intravenosa a todos os pacientes para indução de convulsões. Resultados: A injeção de solução salina foi realizada em 91 pacientes com diagnóstico inicial de CNEP encaminhados ao nosso laboratório de EEG, 57 dos quais eram mulheres e 34 homens. A injeção de solução salina desencadeou um ataque em 82 pacientes (90%). Conclusões: Neste estudo, concluímos que os métodos provocativos são práticos, baratos e, acima de tudo, eficazes para o diagnóstico de pacientes. Na prática clínica, a explicação do diagnóstico é a primeira e mais importante etapa do tratamento, e a comunicação cuidadosa entre médicos e pacientes tem um impacto positivo em seu prognóstico.

Dissecting the role of radical cystectomy and urinary diversion in post-operative complications: an analysis using the American College of Surgeons national surgical quality improvement program database

ABSTRACT Objective: To characterize the contribution of the extirpative and reconstructive portions of radical cystectomy (RC) to complications rates, and assess differences between urinary diversion (UD) types. Materials and Methods: We conducted a retrospective cohort study comparing patients undergoing UD alone or RC+UD for bladder cancer from 2006 to 2017 using ACS National Surgical Quality Improvement Program database. The primary outcome was major complications, while secondary outcomes included minor complications and prolonged length of stay. Propensity score matching (PSM) was utilized to assess the association between surgical procedure (UD alone or RC+UD) and outcomes, stratified by diversion type. Lastly, we examined differences in complication rates between ileal conduit (IC) vs. continent UD (CUD). Results: When comparing RC + IC and IC alone, PSM yielded 424 pairs. IC alone had a lower risk of any complication (HR 0.63, 95% CI 0.52-0.75), venous thromboembolism (HR 0.45, 95% CI 0.22-0.91) and bleeding needing transfusion (HR 0.41, 95% CI 0.32-0.52). This trend was also noted when comparing RC + CUD to CUD alone. CUD had higher risk of complications than IC, both with (56.6% vs 52.3%, p = 0.031) and without RC (47.8% vs 35.1%, p=0.062), and a higher risk of infectious complications, both with (30.5% vs 22.7%, p<0.001) and without RC (34.0% vs 22.0%, p=0.032). Conclusions: RC+UD, as compared to UD alone, is associated with an increased risk of major complications, including bleeding needing transfusion and venous thromboembolism. Additionally, CUD had a higher risk of post-operative complication than IC.

A case of late-onset Klebsiella oxytoca keratitis treated with topical imipenem after deep anterior lamellar keratoplasty / Caso de ceratite de início tardio por Klebsiella oxytoca tratado com imipenem tópico após ceratoplastia lamelar anterior profunda

ABSTRACT The aim of this study was to discuss a case of late-onset Klebsiella oxytoca keratitis after deep anterior lamellar keratoplasty and its treatment. A 21-year-old female patient presented with redness and effluence in the left eye at 5 months after uncomplicated deep anterior lamellar keratoplasty surgery. In the examination, a single suture was loosened in the superior nasal region and there was an infiltration area and epithelial defect in the graft and recipient bed junction in the area of the loose suture. Topical fortified vancomycin and fortified ceftazidime treatment was started empirically hourly, but there was insufficient response. After K. Oxytoca growth in a swab and suture culture taken from the patient, fortified vancomycin was replaced with fortified imipenem. It was observed that the infiltration area rapidly regressed and the epithelial defect was closed after fortified imipenem treatment. Fortified imipenem may be considered as an alternative treatment, especially in cases in which there is no response to treatment and culture growth is detected.(AU)

RESUMO O objetivo deste estudo é discutir um caso de ceratite tardia por Klebsiella oxytoca, após ceratoplastia lamelar anterior profunda, bem como seu tratamento. Uma paciente de 21 anos apresentou vermelhidão e efluxo no olho esquerdo 5 meses após cirurgia de ceratoplastia lamelar anterior profunda sem complicações. Ao exame, havia uma única sutura solta na região nasal superior e uma área de infiltração com defeito epitelial no enxerto e na junção com o leito receptor na área da sutura solta. Iniciou-se empiricamente um tratamento tópico com vancomicina e ceftazidima fortificada de hora em hora, porém com resposta insuficiente. Após o crescimento de K. oxytoca a partir de cultura de swab e sutura retirados da paciente, a vancomicina fortificada foi substituída por imipenem fortificado. Observou-se que a área de infiltração regrediu rapidamente e que o defeito epitelial foi fechado com o tratamento com imipenem fortificado. O imipenem fortificado pode ser considerado um tratamento alternativo, especialmente nos casos sem resposta ao tratamento e detecção de crescimento na cultura.(AU)

Magnesium levels in children with chronic kidney disease stages 1-3 / Niveles de magnesio en niños con enfermedad renal crónica estadios 1-3

ABSTRACT Objective: The objective of this study was to assess serum and urinary magnesium levels in children who have chronic kidney disease stages 1-3. Methods: Eighty-seven patients who were followed at pediatric nephrology department for chronic kidney disease were included in the study. Age, gender, magnesium, dietary magnesium, and creatinine levels, and fractionated magnesium excretion for all cases were recorded. Patients with chronic kidney disease and control groups were compared in terms of these data. Results: Thirty-nine cases with chronic kidney disease were stage 1, 26 were stage 2, and 22 were stage 3. Average age was 9.9 ± 2.8 years in the control group and 10.2 ± 2.6 years in the chronic kidney disease group. The serum magnesium levels were significantly higher in the stage 3 group than in the control group (P<0.001). Also, in stage 3, fractionated magnesium excretion levels were higher compared to the control group (P<0.001). Conclusion: In chronic kidney disease with advancing renal failure, hypermagnesemia is frequently seen. Serum magnesium levels should be measured periodically in all the children with chronic kidney disease stage 3 to investigate magnesium abnormalities and assess clinical results.

RESUMEN Objetivo: El objetivo de este estudio fue evaluar los niveles de magnesio sérico y urinario en niños con enfermedad renal crónica en estadios 1-3. Material y métodos: Se incluyeron en el estudio 87 pacientes que tuvieron seguimiento en el servicio de nefrología pediátrica por enfermedad renal crónica. Se registraron los siguientes datos: edad, sexo, niveles de magnesio, ingesta de alimentos con magnesio, y creatinina, así como también la excreción fraccionada de magnesio para todos estos casos. Sobre la base de dichos datos, se compararon los pacientes con enfermedad renal crónica y los grupos de control. Resultados: De los 87 casos de enfermedad renal crónica, 39 se hallaban en estadio 1; 26, en estadio 2, y 22, en estadio 3. La edad promedio fue de 9,9 ± 2,8 años en el grupo control y de 10,2 ± 2,6 años en el grupo de enfermedad renal crónica. Los niveles de magnesio en suero fueron significativamente más altos en el grupo del estadio 3 que en el grupo control (p <0,001). Además, en el estadio 3, los niveles de excreción fraccionada de magnesio fueron más altos en comparación con el grupo control (p <0,001). Conclusión: En la enfermedad renal crónica con insuficiencia renal avanzada, se observa con frecuencia una hipermagnesemia. Los niveles séricos de magnesio deben medirse periódicamente en todos los niños con enfermedad renal crónica en estadio 3 para investigar las anomalías del magnesio y evaluar los resultados clínicos.
