RESUMEN

PURPOSE: This study aims to adapt and validate the Cleveland Clinic Colorectal Cancer Quality of Life Questionnaire (CCF-CaQL) in Turkish, addressing the significant need for reliable, language-specific QoL measures for colorectal cancer (CRC) in Turkiye. This effort fills a critical gap in CRC patient care, enhancing both patient-provider communication and disease-specific QoL assessment. METHODS: The CCF-CaQL was translated into Turkish, verified for accuracy, and reviewed for clarity and relevance. Eligible patients who underwent colorectal surgery for cancer between July 2021 and July 2022 from six hospitals completed the CCF-CaQL and SF-36 questionnaires. For analysis, confirmatory factor analysis using Smart PLS 4 and descriptive statistics were employed. The questionnaire's reliability and validity were assessed using Cronbach alpha, composite reliability, and the heterotrait-monotrait (HTMT) ratio, along with multicollinearity checks and factor loadings. Nonparametric resampling was used for precise error and confidence interval calculations, and the Spearman coefficient and split-half method were applied for reliability testing. RESULTS: In the study involving 244 colorectal cancer patients, confirmatory factor analysis of the CCF-CaQL indicated effective item performance, with one item removed due to lower factor loading. The questionnaire exhibited high internal consistency, evidenced by a Cronbach alpha value of 0.909. Convergent validity was strong, with all average variance extracted (AVE) values exceeding 0.4. Discriminant validity was confirmed with HTMT coefficients below 0.9, and no significant multicollinearity issues were observed (VIF values < 10). Parallel testing with the SF-36 scale demonstrated moderate to very strong correlations, affirming the CCF-CaQL's comparability in measuring quality of life. CONCLUSION: The Turkish version of the CCF-CaQL was validated for assessing quality of life in colorectal cancer patients. This validation confirms its reliability and cultural appropriateness for use in Turkiye. The disease-specific nature of the CCF-CaQL makes it a useful tool in clinical and research settings, enhancing patient care by accurately monitoring treatment effects and interventions in the Turkish colorectal cancer patient population.

RESUMEN

BACKGROUND: Although chronic urticaria (CU) is a common and primarily affects females, there is little data on how pregnancy interacts with the disease. OBJECTIVE: To analyse the treatment use by CU patients before, during and after pregnancy as well as outcomes of pregnancy. METHODS: PREG-CU is an international, multicentre study of the Urticaria Centers of Reference and Excellence network. Data were collected via a 47-item-questionnaire completed by CU patients who became pregnant during their disease course. RESULTS: Questionnaires from 288 CU patients from 13 countries were analysed. During pregnancy, most patients (60%) used urticaria medication including standard-dose second generation H1-antihistamines (35.1%), first generation H1-antihistamines (7.6%), high-dose second-generation H1-antihistamines (5.6%) and omalizumab (5.6%). The preterm birth rate was 10.2%; rates were similar between patients who did and did not receive treatment during pregnancy (11.6% vs. 8.7%, respectively). Emergency referrals for CU and twin birth were risk factors for preterm birth. The caesarean delivery rate was 51.3%. More than 90% of new-borns were healthy at birth. There was no link between any patient or disease characteristics or treatments and medical problems at birth. CONCLUSION: Most CU patients used treatment during pregnancy especially second-generation antihistamines which seem to be safe during pregnancy regardless of the trimester. The rates of preterm births and medical problems of new-borns in CU patients were similar to population norms and not linked to treatment used during pregnancy. Emergency referrals for CU increased the risk of preterm birth and emphasize the importance of sufficient treatment to keep urticaria under control during pregnancy.

RESUMEN

BACKGROUND: A single-institution retrospective analysis was undertaken to assess long-term results of definitive surgical reconstruction for major bile duct injuries and risk factors for restenosis. METHODS: Patients treated between January 1995 and October 2020 were reviewed retrospectively. The primary outcome measure was patency. RESULTS: Of 417 patients referred to a tertiary center, 290 (69.5%) underwent surgical reconstruction; mostly in the form of a hepaticojejunostomy (n = 281, 96.8%). Major liver resection was undertaken in 18 patients (6.2%). There were 7 postoperative deaths (2.4%). Patency was achieved in 97.4% of primary repairs and 88.8% of re-repairs. Primary patency at three months (including postoperative deaths and stents removed afterwards) in primary repairs was significantly higher than secondary patency attained during the same period in re-repairs (89.3% vs 76.5%, p < 0.01). The actuarial primary patency was also significantly higher compared to the actuarial secondary patency 10 years after reconstruction (86.7% vs 70.4%, p = 0.001). Vascular disruption was the only independent predictor of loss of patency after reconstruction (OR 7.09, 95% CI 3.45-14.49, p < 0.001), showing interaction with injuries at or above the biliary bifurcation (OR 9.52, 95% CI 2.56-33.33, p < 0.001). CONCLUSIONS: Long-term outcome of surgical reconstruction for major bile duct injuries was superior in primary repairs compared to re-repairs. Concomitant vascular injury was independently associated with loss of patency requiring revision.

RESUMEN

The advancing edge profile is a powerful determinant of tumor behavior in many organs. In this study, a grading system assessing the tumor-host interface was developed and tested in 181 pancreatic neuroendocrine tumors (PanNETs), 63 of which were <=2 cm. Three tumor slides representative of the spectrum (least, medium, and most) of invasiveness at the advancing edge of the tumor were selected, and then each slide was scored as follows. Well-demarcated/encapsulated, 1 point; Mildly irregular borders and/or minimal infiltration into adjacent tissue, 2 points; Infiltrative edges with several clusters beyond the main tumor but still relatively close, and/or satellite demarcated nodules, 3 points; No demarcation, several cellular clusters away from the tumor, 4 points; Exuberantly infiltrative pattern, scirrhous growth, dissecting the normal parenchymal elements, 5 points. The sum of the rankings on the three slides was obtained. Cases with scores of 3-6 were defined as "non/minimally infiltrative" (NI; n = 77), 7-9 as "moderately infiltrative" (MI; n = 68), and 10-15 as "highly infiltrative" (HI; n = 36). In addition to showing a statistically significant correlation with all the established signs of aggressiveness (grade, size, T-stage), this grading system was found to be the most significant predictor of adverse outcomes (metastasis, progression, and death) on multivariate analysis, more strongly than T-stage, while Ki-67 index did not stand the multivariate test. As importantly, cases <=2 cm were also stratified by this grading system rendering it applicable also to this group that is currently placed in "watchful waiting" protocols. In conclusion, the proposed grading system has a strong, independent prognostic value and therefore should be considered for integration into routine pathology practice after being evaluated in validation studies with larger series.

RESUMEN

We evaluated the relationship between erectile dysfunction (ED) and IL-6 levels in males with COVID-19. The study included 80 male patients aged 30-45 years who were hospitalised due to COVID-19. The International Index of Erectile Function (IIEF-5) questionnaire was used to assess erectile function. The IIEF-5 questionnaire was re-administered at a 3-month control visit after discharge, and the change score from baseline was recorded. The patients were divided into three groups according to the IIEF-5 score at 3 months as Group 1 (severe ED), Group 2 (moderate ED) and Group 3 (no ED), and into two groups according to IL-6 level at the time of admission as Group A (IL-6 ≤ 50 ng/ml) and Group B (IL-6 > 50 ng/ml). The change in the IIEF-5 score (p < .001) was significantly greater in Group B than in Group A. There was also significant difference in IL-6 between Group 1 and Group 2 (p = .008). The correlation analysis revealed a moderate correlation between IL-6 level and the change in IIEF-5 score and D-dimer level (r:0.529, p < .001) and a weak correlation between IL-6 level and FSH (r:0.309, p = .005). The present study suggests that elevated IL-6 levels in male patients hospitalised due to COVID-19 might be related to the risk of developing ED.

RESUMEN

The use of the second trimester alpha-fetoprotein (AFP) along with the first trimester pregnancy-associated plasma protein-A (PAPP-A) has been found to be useful in the estimation of unfavourable pregnancy outcome. Our aim in this study was to determine the relationship between maternal PAPP-A and b-hCG and AFP concentrations in spontaneous preterm birth (sPTB). This prospective cohort study included 372 singleton pregnancies with PAPP-A, b-hCG and AFP levels in the first trimester, which were converted to multiples of the median (MoM). The predictive ability of AFP-to-PAPP-A and AFP-to-b-hCG ratios for sPTB was evaluated. The risk for sPTB ≤34 weeks increased in women with AFP-to-PAPP-A ratio >7 (OR 2.9, 95% CI 1.2-6.4). Women with AFP-to-b-hCG ratio >0.6 had a 3.5-fold higher risk for sPTB ≤32 weeks. Increased maternal AFP-to-PAPP-A or AFP-to-b-hCG ratios in the first trimester may help to predict pregnant women at high risk for sPTB, and this may be beneficial in developing management plans.Impact StatementWhat is already known on this subject? There is a synergistic association between the combination of low pregnancy-associated plasma protein-A (PAPP-A) in the first trimester with alpha-fetoprotein (AFP) in the second trimester with subsequent development of PTB. Maternal serum biochemical markers measured as a part of aneuploidy screening are reflective of pregnancy adverse outcomes related with placental insufficiency. PAPP-A and AFP have a low predictive ability to determine women at high risk for preterm birth.What do the results of this study add? Elevated AFP:PAPP-A or AFP:B-HCG ratio in the first trimester is associated with increased risk for sPTB. The ratios of these biochemical markers in the first trimester may be beneficial to identify women at high risk for sPTB.What are the implications of these findings for clinical practice and/or further research? The ratios may predict pregnant women at high risk for sPTB, and such risk may be helpful in the development of a management plan. Incorporation of AFP:PAPP-A or AFP:B-HCG ratios in the first trimester may help to improve the screening efficacies, and provide a simple alternative tool.

RESUMEN

BACKGROUND: 25-hydroxy VD insufficiency is known in children undergoing LT but the serial post-transplant VD course and supplementation modalities in the peri-transplant period are lacking. We aimed to determine the pre-VD status and the post-transplant VD status course following VD supplementation and to elucidate its relationship with post-transplant outcome parameters such as infection and survival. METHODS: Pre- and post-VD levels were monitored in parallel with interventions to adjust VD levels in LT patients. VD status was categorized as circulating levels <30-21 ng/ml (insufficiency), 20-10 ng/ml (deficiency), and <10 ng/ml (severe deficiency). Patients received stoss (300000IU) VD3 within the pretransplant period if serum levels were <20 ng/ml. RESULTS: 135 transplanted children were included. The age at LT was 22 months (IQR: 8-60). The pretransplant median VD level was 14 ng/ml. Despite stoss dose, post-transplant median VD level was 1.8 ng/ml (day one), 4 ng/ml (week one), 19 ng/ml (month one), 33 ng/ml (month three), 38 ng/ml (months 6-12), and 40 ng/ml (month 24). After 6 months, VD status reached >30 ng/ml in 98% of patients. Only at pre-LT, higher infection rate (18.7%) in the severe VD deficiency group was observed compared to the VD deficiency group (2.9%, p = .04). Survival was not affected by serum VD levels. CONCLUSION: VD levels fell substantially after LT but are rectifiable by stoss dose, which was well tolerated. Only the infection rate was associated with the VD status.

RESUMEN

BACKGROUND: Since the daily creatinine excretion rate (CER) is directly affected by muscle mass, which varies with age, gender, and body weight, using the spot protein/creatinine ratio (Spot P/Cr) follow-up of proteinuria may not always be accurate. Estimated creatinine excretion rate (eCER) can be calculated from spot urine samples with formulas derived from anthropometric factors. Multiplying Spot P/Cr by eCER gives the estimated protein excretion rate (ePER). We aimed to determine the most applicable equation for predicting daily CER and examine whether ePER values acquired from different equations can anticipate measured 24 h urine protein (m24 h UP) better than Spot P/Cr in pediatric kidney transplant recipients. METHODS: This study enrolled 23 children with kidney transplantation. To estimate m24 h UP, we calculated eCER and ePER values with three formulas adapted to children (Cockcroft-Gault, Ghazali-Barratt, and Hellerstein). To evaluate the accuracy of the methods, Passing-Bablok and Bland-Altman analysis were used. RESULTS: A statistically significant correlation was found between m24 h UP and Spot P/Cr (p < .001, r = 0.850), and the correlation was enhanced by multiplying the Spot P/Cr by the eCER equations. The average bias of the ePER formulas adjusted by the Cockcroft-Gault, Ghazali-Barratt, and Hellerstein equations were -0.067, 0.031, and 0.064 g/day, respectively, whereas the average bias of Spot P/Cr was -0.270 g/day obtained by the Bland-Altman graphics. CONCLUSION: Using equations to estimate eCER may improve the accuracy and reduce the spot urine samples' bias in pediatric kidney transplantation recipients. Further studies in larger populations are needed for ePER reporting to be ready for clinical practice.

RESUMEN

Introduction: Estrogen helps to maintain the health of collagen-containing tissues including the intervertebral disc. Estrogen deficiency after menopause negatively affects the quality of vertebral end plates and induces development of degenerative disc disease (DDD). However, there is no study examining the relationship between parity and spinal degeneration in young women. The aim of this study was to define the relationship between parity and development of vertebral endplate signal changes and DDD in young premenopausal women.Materials and methods: This case-control case study included 224 patients aged 20-40 years with a history of low back pain for at least 3 months. Pfirrmann's grade, Modic changes (MCs), and Schmorl's nodes (SNs) were graded based on magnetic resonance images. Patients' parity, demographics, body mass index, physical activity level, and disability scores were assessed using a questionnaire.Results: The prevalence of abnormal total Pfirrmann's score (>10) and MCs was higher in primiparous patients than multiparous and grand-multiparous; however, it was not statistically significant. The presence of SN was statistically significantly associated with low parity. According to multivariate logistic regression analysis, it was found that the number of births increases by 1 unit, the abnormality in Pfirrmann's score decreases by 1.36 times.Conclusions: This cross-sectional study shows that parity is associated with DDD and vertebral end plate changes. SNs were significantly associated with parity. Modic changes and DDD were less common in grand multipara and multipara young women than in primipara women. These results indicate that low parity may possibly be associated with the development of spinal degeneration.

RESUMEN

BACKGROUND: The prevalence rates for both sarcopenia and erectile dysfunction (ED) gradually increase in middle-aged and elderly diabetic male population and they impair physical functioning, sexual functioning, and quality of life. The aim of the present study was to evaluate the sarcopenia in patients with diabetic ED. METHODS: The study included 98 male patients with type II diabetes mellitus (DM) aged 18-80 years. Blood chemistry and hormone levels were obtained. The International Index of Erectile Function (IIEF-5) questionnaire was administered to the patients. The patients were divided into three groups according to the IIEF-5 score; a score of 5-10 points indicated severe ED, a score of 11-20 indicated moderate ED, and a score of 21-25 points indicated no ED. The muscle mass, handgrip strength, timed up and go test, upper mid-arm circumference, calf circumference, and body mass index were obtained. The statistical analysis was performed using MedCalc Statistical Software version 12.7.7. All parameters were compared between the three groups. RESULTS: Of 98 patients included in the study, 84 patients had severe sarcopenia, 13 had moderate sarcopenia, while only one patient had normal muscle mass. The mean age was 56.59 ± 11.46 years. When patients were divided into three groups according to IIEF-5 score, 38 had severe ED, 39 had moderate ED, and 21 had no ED. There was a significant difference between the three groups in terms of handgrip strength, timed up and go test scores, upper mid-arm circumference, and calf circumference (p < .05 for all). CONCLUSIONS: Although muscle mass remains unchanged, muscle strength and physical performance decrease in diabetic ED patients. Diabetic patients with severe and moderate ED have lower muscle strength and physical performance.

RESUMEN

OBJECTIVES: We present the first study validating the recent Dako ALK assay (clone OTI1A4, in vitro diagnostic) for detecting ALK rearrangements in lung adenocarcinoma. METHODS: Lung adenocarcinoma cases between 2011 and 2023 were retrospectively collected to create a cohort of 203 samples. Cases were stained with Dako ALK OTI1A4 and Ventana ALK D5F3 and reviewed by 3 pathologists independently. Correlation between assays, including their sensitivity and specificity, was evaluated. RESULTS: The cohort (n = 203) consisted of resections, core needle biopsies, and cell blocks. Agreement between Dako ALK OTI1A4 and Ventana ALK D5F3 assays was "almost perfect," with κ = 0.89. The sensitivity and specificity of the Dako ALK OTI1A4 assay were 93.3% and 96%, respectively, in a subgroup of 55 molecularly confirmed cases (n = 30 with and n = 25 without ALK rearrangement). CONCLUSIONS: Immunohistochemistry-based assays provide a valid and reasonably priced alternative, especially in settings where molecular confirmatory tests are neither offered nor accessible. Given high interassay and molecular concordance, we propose that the novel Dako OTI1A4 assay can be reliably used to identify cases with ALK rearrangement.

RESUMEN

(1) Background: The Berlin questionnaire (BQ) is a widely used survey to predict obstructive sleep apnea (OSA). Considering the confounding effect of obesity and hypertension on the clinical course of COVID-19, we have recently developed a modified BQ (mBQ) based on the subscales snoring intensity/frequency, witnessed apneas and morning/daytime tiredness, and demonstrated that patients with high-risk OSA had worse outcomes during the COVID-19 pandemic. In the current study, we aimed to validate the mBQ in adults with a history of COVID-19 infection. (2) Method: All cases who suffered from COVID-19 infection between 10 March and 22 June 2020, and who completed the mBQ in our first study, were invited to participate. Participants refilled the questionnaires, and an attended polysomnography (PSG) was conducted. An apnea-hypopnea index (AHI) of 15 events/h or more was considered as OSA. (3) Results: Out of the 70 participants, 27 (39%) were categorized as having a high risk of OSA based on the mBQ. According to the PSG results, 24 patients with high-risk OSA (89%) and 3 patients with low-risk OSA on the mBQ (7%) had AHI ≥ 15 events/h. The mBQ had a sensitivity of 89%, a specificity of 93%, a positive predictive value of 89%, a negative predictive value of 93%, and an accuracy of 91%. The area under the curve was 0.91 confirming a very good performance of the mBQ in screening for OSA. (4) Conclusions: The mBQ has a good level of diagnostic sensitivity, specificity, and accuracy among adults with a history of COVID-19 infection. Since the confounding effects of obesity and hypertension are eliminated, the mBQ may be used not only as a screening tool for high-risk OSA but also as a prognostic survey in clinical cohorts.

RESUMEN

Background: In this study, we aimed to evaluate the outcomes of our on-table extubation strategy in patients with congenital heart disease. Methods: Between April 2021 and November 2022, a total of 114 pediatric patients (58 males, 56 females; median age: 25.3 months; range, 57.5 to 4.4 months) who were operated for congenital heart diseases were retrospectively analyzed. The patients were evaluated according to the Society of Thoracic Surgeons-European Association for Cardio-Thoracic Surgery (STS-EACTS) scoring system. Perioperative patient data were analyzed and correlated with the extubation status. Results: Overall, 56% of the patients were extubated in the operating room. There was an association between fluid balance per unit body surface area, longer cardiopulmonary bypass and cross-clamp times and on-table extubation. Lactate value prior to extubation, STS-EACTS mortality category, estimated mortality, and estimated morbidity were statistically significant with regards to the achievability of extubation. Multivariate analysis revealed lactate value prior to extubation and estimated postoperative length of hospital stay to be significant factors affecting on-table extubation. There was a significant correlation between decreased length of intensive care unit and hospital stay and on-table extubation. Conclusion: The outcomes of our on-table extubation strategy for patients with congenital heart disease reveal the feasibility of this approach. Higher lactate and fluid balance/body surface area levels, longer cross-clamp and cardiopulmonary bypass durations, increased surgical complexity are indicators of a failure to perform on-table extubation. This strategy is also associated with shorter intensive care unit and hospital length of stays as an additional clinical benefit.

RESUMEN

Introduction: Pilocytic astrocytoma (PA) is one of the most common primary intracranial neoplasms in childhood with an overall favorable prognosis. Despite decades of experience, there are still diagnostic and treatment challenges and unresolved issues regarding risk factors associated with recurrence, most often due to conclusions of publications with limited data. We analyzed 499 patients with PA diagnosed in a single institution over 30 years in order to provide answers to some of the unresolved issues. Materials and Methods: We identified pilocytic astrocytomas diagnosed at the University of California, San Francisco, between 1989 and 2019, confirmed the diagnoses using the WHO 2021 essential and desirable criteria, and performed a retrospective review of the demographic and clinical features of the patients and the radiological, pathologic and molecular features of the tumors. Results: Among the patients identified from pathology archives, 499 cases fulfilled the inclusion criteria. Median age at presentation was 12 years (range 3.5 months - 73 years) and the median follow-up was 78.5 months. Tumors were predominantly located in the posterior fossa (52.6%). There were six deaths, but there were confounding factors that prevented a clear association of death to tumor progression. Extent of resection was the only significant factor for recurrence-free survival. Recurrence-free survival time was 321.0 months for gross total resection, compared to 160.9 months for subtotal resection (log rank, p <0.001). Conclusion: Multivariate analysis was able to identify extent of resection as the only significant variable to influence recurrence-free survival. We did not find a statistically significant association between age, NF1 status, tumor location, molecular alterations, and outcome. Smaller series with apparently significant results may have suffered from limited sample size, limited variables, acceptance of univariate analysis findings as well as a larger p value for biological significance. PA still remains a predominantly surgical disease and every attempt should be made to achieve gross total resection since this appears to be the most reliable predictor of recurrence-free survival.

RESUMEN

BACKGROUND: Various tools have been created to measure physical function during intensive care unit (ICU) stay and after ICU discharge, but those have not been validated in coronavirus 2019 (COVID-19) patients. There is a need for a reliable, valid and feasible tool to define the rehabilitation needs of post-ICU COVID-19 patients entering the acute wards and then rehabilitation clinics. OBJECTIVE: This study aims to investigate the validity, inter-rater reliability and feasibility of Chelsea Physical Assessment Tool (CPAx) in assessing the functional status of COVID-19 patients after discharge from the ICU. METHODS: Demographic and clinical characteristics of the patients were recorded. Patients were evaluated using the modified Medical Research Council (MRC) dyspnea scale, Functional Oral Intake Scale, Glasgow Coma Scale, CPAx, Barthel Index, Katz Index and MRC sum score, measurements of grip strength obtained by dynamometer, the 5 time sit-to-stand test and 30 seconds and sit-to-stand test. CPAx and the other functional assessment tools were administered to 16 patients within 48 hours following ICU discharge. For inter-rater reliability, another physiatrist independently re-assessed the patients. MRC sum score, Barthel and Katz indexes were used to assess construct validity of CPAx. The discriminative validity of CPAx was determined by its ability to differentiate between patients with and without ICU acquired muscle weakness based on MRC sum score. The intra-class correlation coefficients (ICC) were calculated to determine inter-rater reliability for total scores of the functional assessment tools. Cohen's Kappa (κ) coefficient and weighed Kappa (κw) were calculated to determine inter-rater reliability of individual CPAx items. Ceiling and flooring effects were calculated by percentage frequency of lowest or highest possible score achieved. The number and percentages of the patients who were able to complete each tool were calculated to assess feasibility. The CPAx score was strongly correlated with MRC sum score (rho: 0.83), Barthel Index (rho: 0.87) and Katz Index (rho: 0.89) (p< 0.001) showing construct validity. Area under the ROC curve demonstrated that cut off score for CPAx was ⩽ 12 to discriminate patients with MRC sum score < 48, with a sensitivity and a specificity of 100% and 63%, respectively (AUC = 0.859, p< 0.001). ICC was high for CPAx, MRC sum score, Barthel and Katz indexes, Glasgow Coma Scale, and hand grip strength measurement, with the highest value observed for CPAx (ICC, 0.96; 95% confidence interval (CI), 0.71-0.98). κ and κw analysis showed good to excellent inter-rater reliability for individual CPAx items. No floor or ceiling effect was observed at CPAx while floor effect was observed at Barthel Index scores (25%) and Katz Index scores (37.5%). All patients could be evaluated using CPAx while less were physically able to complete the 5 time sit-to-stand, 30 seconds sit-to-stand tests (n= 4) and MRC sum score (n= 14). CONCLUSION: CPAx is a valid, reliable, and feasible tool to assess the physical functional state in COVID-19 patients following discharge from the ICU.

RESUMEN

Objective: Irrational use of antibacterials is a concern during the COVID-19 pandemic. Hospital pharmacoepidemiology studies are important for evaluating the rational use of medicines, especially antibacterials, during pandemics. Defined daily doses (DDD) and drug utilization 90% (DU90%) are established methods for the evaluation of drug utilization. We aimed to evaluate antibacterial utilization in a tertiary hospital setting at Koç University Hospital (KUH). Materials and Methods: This cross-sectional, descriptive study was retrospectively conducted with data extracted from KUH Inpatient Electronic Order System (CP) and was carried out for a period of one year. Antibacterial utilization of adult (aged ≥ 18 years) inpatients, who were prescribed at least one type of systemic antibacterial (ATC code J01), was evaluated using the recommended parameter DDD/100 admission and compared between 6 months before COVID-19 and during COVID-19 periods. March 11, 2020, the very first COVID-19 diagnosed case in Turkey, was set as the cutoff date of the 6-month period for the selection of the compared antibacterials using the DU90% method. Results: Finally, 3280 of 5942 and 2605 of 4942 prescriptions for pre-COVID-19 and COVID-19 periods were included, respectively. Antibacterial utilization according to DDD/100 admissions increased from 193.96 to 201.26 DDD/100 admissions after the initiation of COVID-19 pandemic. The most utilized antibacterials were piperacillin and enzyme inhibitors in pre-COVID-19 period, whereas meropenem was utilized the most during COVID-19 period. Azithromycin utilization increased by 656.24%, whereas clarithromycin utilization decreased by 52.12%. Antibacterials were utilized most in general surgery department, with an increase of 17.57%. Conclusion: There is an increase in antibacterial utilization in KUH during COVID-19 pandemic, especially reserved antibacterials, which is a concern for antibacterial resistance.

RESUMEN

Purpose: Since quantification and communication of ocular pain is important for a healthier patient follow-up and postoperative guidance, reliable measures like the Ophthalmic Pain Assessment Survey (OPAS) are needed to assess the outcome and management of different operations. To address that need, we carried out the adaptation of OPAS into Turkish to reach different age groups and backgrounds, widening the use of OPAS on patients who underwent an ophthalmic operation. Methods: We used back-translation method and achieved cultural adaptation through content validity scoring by 5 independent ophthalmologists. The survey is then administered three times: preoperatively, postoperatively within 24 hours, and finally a week later in the follow-up visit. Validity is measured in comparison to Visual Analog Scale using Spearman's correlation coefficient and reliability is measured using Cronbach's alpha. Factor analysis is performed by principal component analysis and rotation is performed using Varimax method when necessary. Results: We reached a total of 132 patients with a mean age of 64.2 years. Most of them underwent phacoemulsification (n = 83), followed by PRK (n = 37). Overall, the T-OPAS demonstrated good reliability (mean C. alpha: 0.830) and its correlation with the VAS was especially high (S. coeff. >0.5) in the first three sections in all three surveys. Factor analysis yielded 5 subscales, allowing us to shape the final form of T-OPAS. Conclusion: Through this adaptation of OPAS into a foreign language, we present a reliable and valid tool for postoperative pain quantification, allowing objective measurement of pain in different populations such as the elderly.

RESUMEN

The Paediatric Eosinophilic Esophagitis Symptom Severity Modules Version 2.0 (T-PEESv2.0) was developed in English as a valid, reliable questionnaire for follow up. This work aimed to develop a Turkish version of T-PEESv2.0 via translation and cultural adaptation and then to test its validation and reliability. Methods: The PEESv2.0 was translated into Turkish by standardized procedural steps completed in cooperation with the Mapi Research Trust. The final version of the questionnaire was submitted to eosinophilic oesophagitis patients or their parents at 2 times point separated by 1 week. An age-matched control group was used to test the discriminant validity. Construct validity was tested using the Wilcoxon test, and internal consistency was tested using Cronbach's alpha. Test-retest reliability was measured with Cohen's kappa and intraclass correlation coefficient. Results: One hundred twenty-eight participants (70 patients, 58 parents) were enrolled. Fifty-eight (39.1%) of them completed T-PEESv2.0-parent by proxy and 70 (54.7%) were T-PEESv2.0. The Cronbach's alpha coefficient and intraclass correlation coefficient for test-retest reliability were >0.70 for both questionnaires and for all domain (frequency and severity) and total scores. For discriminant validity analysis, subscale (frequency and domain) and total scores of the patient group were compared with those of the control group. The subscale and total scores were significantly different between the groups (P < 0.05). Conclusion: T-PEESv2.0 appeared to be valid and reliable, ready to be introduced as a clinical and research tool for the assessment of patients with eosinophilic oesophagitis.

RESUMEN

BACKGROUND: Acute kidney injury (AKI) in COVID-19 patients is associated with poor prognosis. However, the incidence, risk factors and potential outcomes of AKI in hospitalized patients are not well studied. MATERIALS AND METHODS:  This is a retrospective cohort study conducted in two major university hospitals. Electronic health records of the patients, 18 years or older, hospitalized between 13 April and 1 June 2020 with confirmed COVID-19 were reviewed. We described the incidence and the risk factors for AKI development in COVID-19 patients. Furthermore, we investigated the effects of AKI on the length of hospital and intensive care unit (ICU) stay, the admission rates to ICU, the percentage of patients with cytokine storm and in-hospital mortality rate. RESULTS: Among 770 hospitalized patients included in this study, 92 (11.9%) patients developed AKI. The length of hospitalized days (16 vs 9.9, p < 0.001) and days spent in the hospital until ICU admission (3.5 vs. 2.5, p = 0.003) were higher in the AKI group compared to patients without AKI. In addition, ICU admission rates were also significantly higher in patients with AKI (63% vs. 20.7%, p < 0.001). The percentage of patients with AKI who developed cytokine storm was significantly higher than patients without AKI (25.9% vs. 14%, p = 0.009). Furthermore, the in-hospital mortality rate was significantly higher in patients with AKI (47.2% vs. 4.7%, p < 0.001). CONCLUSIONS: AKI is common in hospitalized COVID-19 patients. Furthermore, we show that AKI increases the admission rates to ICU and in-hospital mortality. Our findings suggest that AKI should be effectively managed to prevent the adverse outcomes in COVID-19 patients.
