SUMMARY OBJECTIVE: The objective of this study was to compare the nutritional status and dietary intake of pregnant women with sickle cell disease (SS hemoglobinopathy and SC hemoglobinopathy) to healthy controls and report the maternal and perinatal outcomes. METHODS: This is a prospective, longitudinal cohort study. Pregnant women with a diagnosis of sickle cell disease and control group were recruited in an outpatient clinic of a tertiary care hospital in São Paulo, Brazil. Maternal anthropometric data and dietary intake data were collected at the second and third trimesters. RESULTS: A total of 49 pregnancies complicated by sickle cell disease were included. Prepregnancy body mass index was significantly lower in the SS hemoglobinopathy group (n=26, median 20.3 kg/m2) than the SC hemoglobinopathy group (n=23, 22.7 kg/m2) or control group (n=33, 23.2 kg/m2, p<0.05). The prepregnancy nutritional status revealed significantly more women classified as underweight in the SS hemoglobinopathy group (15.4%) than in the SC hemoglobinopathy group (4.4%) and control group (1.6%, p=0.009). In the second trimester, maternal protein intake was significantly lower in SS hemoglobinopathy (73.2 g/day) and SC hemoglobinopathy (68.8 g/day) than in the control group (95.7 g/day, p=0.004). In the third trimester, only SS hemoglobinopathy mothers showed dietary intake of protein significantly lower than that of the controls (67.5 g/day vs. 92.8 g/day, p=0.02). Vitamin A and E consumption was also reduced in the third trimester in the SS hemoglobinopathy group (p<0.05). CONCLUSION: The nutritional status of pregnant women with SS hemoglobinopathy is characterized by a state of undernutrition. The lower protein intake in the second and third trimesters of pregnant women with SS hemoglobinopathy may contribute to this condition. Undernourishment is a serious complication of sickle cell disease, primarily during pregnancy, and it should be addressed during the prenatal period.

SUMMARY OBJECTIVE: This study aimed to evaluate the association between self-reported race/color and ancestry in Brazilian patients with breast cancer. METHODS: This was an observational, transversal, epidemiological study, evaluating race and ancestry in 1,127 patients with breast cancer. For genetic ancestry, a 46-AIM-INDEL panel was used. The ancestral profile was evaluated with the Structure v.2.3.3 software. Descriptive statistics were performed. To assess differences between race and ancestry, an analysis of variance with Bonferoni adjustment was used. RESULTS: The race distribution was 77.7% white, 17.6% brown, 4.1% black, 0.4% yellow, and 0.3% cafuse. The African ancestry proportion was significantly (p<0.001) more evident in black [0.63±0.21 (0.17–0.96)], followed by brown [0.25±0.16 (0.02–0.70)], and less frequent in white skin color. The European ancestry proportion was significantly (p<0.001) higher in white [0.72±0.17 (0.02–0.97)], followed by brown [0.57±0.19 (0.12–0.92)], yellow [0.27±0.31 (0.12–0.620], and black [0.24±0.19 (0.02–0.72)]. The Asiatic ancestry proportion is significantly (p<0.001) higher in yellow [0.48±0.51 (0.04–0.93)]. The Amerindian ancestry proportion frequency was the least frequent in all groups, and cafuse patients did not express differences between all race groups. The brown race group presented differences in African and European ancestry. CONCLUSION: Although we found many similarities between white European ancestry, black African ancestry, and yellow Asian ancestry, there is great miscegenation between patients. Although they can be labeled as having one race, they do present many ancestral genes that would allow their inclusion in another race group.

SUMMARY OBJECTIVE: In-hospital cardiac arrest is a critical medical emergency. Knowledge of prognostic factors could assist in cardiopulmonary resuscitation decision-making. Frailty and functional status are emerging risk factors and may play a role in prognostication. The objective was to evaluate the association between reduced mobility and in-hospital cardiac arrest outcomes. METHODS: This retrospective cohort study included patients over 18 years of age with in-hospital cardiac arrest in Botucatu, Brazil, from April 2018 to December 2021. Exclusion criteria were patients with a do-not-resuscitate order or patients with recurrent in-hospital cardiac arrest. Reduced mobility was defined as the need for a bed bath 48 h before in-hospital cardiac arrest. The outcomes of no return of spontaneous circulation and in-hospital mortality were evaluated. RESULTS: A total of 387 patients were included in the analysis. The mean age was 65.4±14.8 years; 53.7% were males and 75.4% had reduced mobility. Among the evaluated outcomes, the no return of spontaneous circulation rate was 57.1%, and in-hospital mortality was 94.3%. In multivariate analysis, reduced mobility was associated with no return of spontaneous circulation when adjusted by age, gender, initial shockable rhythm, duration of cardiopulmonary resuscitation, and epinephrine administration. However, in multiple logistic regression, there was no association between reduced mobility and in-hospital mortality. CONCLUSION: In patients with in-hospital cardiac arrest, reduced mobility is associated with no return of spontaneous circulation. However, there is no relation to in-hospital mortality.

SUMMARY OBJECTIVE: The aim of this study was to investigate the role of irisin in type 2 diabetes mellitus and its association with metabolic alterations and obesity. METHODS: A cross-sectional case-control study was conducted on participants treated at Centro Universitário FMABC between August 2018 and July 2019, by comparing a control group (n=14) with type 2 diabetes mellitus patients (n=16). The control group consisted of participants aged above 21 years with no chronic diseases, diabetes, smoking, or illicit drug use. The type 2 diabetes mellitus group included patients aged above 21 years, who were diagnosed with type 2 diabetes for at least 5 years (glycated hemoglobin>7%). Exclusion criteria were not willing to continue, recent hospitalization, and failure to meet inclusion criteria. Biochemical parameters included blood glucose, glycated hemoglobin, plasma irisin levels, and irisin gene expression in peripheral blood. RESULTS: Type 2 diabetes mellitus patients exhibited significantly higher plasma glucose levels [143 (40) vs. 92 (13) mg/dL, *p<0.05] and glycated hemoglobin levels [7.1% (1.6) vs. 5.6% (0.5), *p<0.05] compared to the control group. Irisin gene expression in type 2 diabetes mellitus patients was lower 0.02288 (0.08050) than the control group 8.506e-006 (1.412e-005) (p=0.06). Correlation analysis revealed a positive association between irisin expression and body mass index in type 2 diabetes mellitus (Rho=0.5221, 95%CI -0.058 to 0.838, p=0.06), while plasma irisin showed a negative correlation with body mass index (Rho=-0.656, 95%CI -0.836 to 0.215, p=0.03). No significant correlations were found between plasma glucose or glycated hemoglobin levels and irisin expression. CONCLUSION: The data suggests that body mass index directly influences plasma irisin levels and the regulation of irisin gene expression, possibly linking irisin to adiposity changes observed in obesity-related type 2 diabetes mellitus.

SUMMARY OBJECTIVE: The objective of this study was to evaluate cytogenetic changes in individuals submitted to oral human immunodeficiency virus pre-exposure prophylaxis use through the micronucleus test in oral mucosa. METHODS: This study consisted of 37 individuals, of whom 17 comprised the pre-exposure prophylaxis group and 20 comprised the control group. A total of 2,000 cells per slide were analyzed for the determination of micronuclei, binucleation, nuclear buds, and cytotoxicity parameters: pyknosis, karyolysis, and karyorrhexis (KR), in a double-blind manner. The repair index was also evaluated in this setting. RESULTS: In the mutagenicity parameters, the pre-exposure prophylaxis group showed increased frequencies of micronuclei (p=0.0001), binucleation (p=0.001), and nuclear buds (p=0.07). Regarding the cytotoxicity parameters, there was an increase with a statistical difference (p≤0.05) in the karyorrhexis frequency (p=0.001). Additionally, the repair system efficiency decreased in the pre-exposure prophylaxis group. CONCLUSION: These results indicate that individuals undergoing pre-exposure prophylaxis use have geno- and cytotoxicity in oral mucosal cells.

SUMMARY OBJECTIVE: The objectives of this study were to translate and cross-culturally adapt the telehealth usability questionnaire into Brazilian Portuguese and to evaluate its psychometric properties. METHODS: This was a methodological validation study carried out in two phases. In phase 1, the telehealth usability questionnaire was cross-culturally adapted with 10 participants comprising the expert committee members, including 5 healthcare professionals with theoretical and practical knowledge of telehealth, 1 methodologist, and 4 translators. This phase was performed at Universidade Federal de Juiz de Fora Physiotherapy Clinic School. In phase 2, the psychometric properties of telehealth usability questionnaire Brazil were analyzed. This phase included in-person assessments at Márcio Cunha Hospital, Minas Gerais. The recruitment period for both phases was from April 2020 to February 2021. Content validity, reliability, internal consistency, and criterion validity were analyzed. The criterion validity was evaluated using correlation with a validated instrument: the system usability scale. RESULTS: The telehealth usability questionnaire was adequately translated and cross-culturally adapted. The telehealth usability questionnaire Brazil presented an excellent content validity index of 0.96 with percentages of understanding higher than 90%. The telehealth usability questionnaire Brazil demonstrated great internal consistency (α=0.94 and ω=0.94), excellent intra-rater reliability (intraclass correlation coefficient=0.85, 95%CI 0.75–0.91), no difference between the test and retest [T (0.425), p>0.673], and no proportional bias (p=0.205). There was a moderate correlation between telehealth usability questionnaire Brazil and the system usability scale (r=0.52, p<0.0001). CONCLUSION: The telehealth usability questionnaire was adequately translated and cross-culturally adapted into Brazilian Portuguese and showed adequate psychometric properties for use in telehealth clinical practice and research in Brazilian-Portuguese-speaking individuals.

SUMMARY OBJECTIVE: Respiratory bronchiolitis is a disease associated with heavy smoking. Computed tomography in this disease often shows symmetrical and bilaterally ill-defined circumscribed centriacinar micronodular involvement in the upper-middle lobes. The maximum intensity projection method is a kind of image processing method and provides a better evaluation of nodules and vascular structures. Our study aimed to show whether maximum intensity projection images increase the diagnostic accuracy in the detection of micronodules in respiratory bronchiolitis. METHODS: Two radiologists with different experiences (first reader: 10-year radiologist with cardiothoracic radiology experience and second reader: nonspecific radiologist with 2 years of experience) reviewed images of patients whose respiratory bronchiolitis diagnosis was supported by clinical findings. The evaluation was done independently of each other. Both conventional computed tomography images and maximum intensity projection images of the same patients were examined. The detection rates on conventional computed tomography and maximum intensity projection images were then compared. RESULTS: A total of 53 patients were evaluated, of whom 48 were men and 5 were women. The first reader detected centriacinar nodules in 42 (79.2%) patients on conventional computed tomography and centriacinar nodules in all 53 (100%) patients on maximum intensity projection images. The second reader detected centriacinar nodules in 12 (22.6%) patients on conventional computed tomography images and in 48 (90.6%) patients on maximum intensity projection images. For the less experienced reader, the detection rate of micronodules in respiratory bronchiolitis in maximum intensity projection images increased statistically significantly (p<0.001). CONCLUSION: Maximum intensity projection images in respiratory bronchiolitis increase the detectability of micronodules independently of the experience of the radiologist.

SUMMARY OBJECTIVE: The aim of this study was to investigate the impact of sarcopenia on prognosis in patients with gastric cancer in order to explore the relationship between sarcopenia and postoperative complications as well as durations of hospital stay and intensive care unit. METHODS: A total of 175 patients who visited the oncology clinic between 2017 and 2022 with respect to their radiological images, demographic data, and laboratory parameters were perused. The OsiriX software was used to measure the skeletal muscle area that was divided by the body height in order to obtain the skeletal muscle index. RESULTS: A total of 50.28% of 175 patients (41 females and 134 males, with a mean age of 63.5 years) who met the inclusion criteria in the study were sarcopenic. Significant differences appeared between sarcopenic and non-sarcopenic patients with respect to durations of both hospital stay (p<0.01) and intensive care unit stay (p<0.01) (multivariate analysis). Furthermore, patients with sarcopenia had significantly frequent postoperative complications in comparison with those without sarcopenia. Among the patients with sarcopenia, decreased levels of hemoglobin and albumin as well as lymphocytes were encountered in terms of inflammatory markers; nevertheless, no significant differences were determined among other inflammatory markers. CONCLUSION: In patients undergoing treatment for gastric cancer, sarcopenia increases postoperative complications and prolongs hospital and intensive care stays during the treatment process.

SUMMARY OBJECTIVE: Intragastric balloon placement is an effective method for weight reduction. The aim of this study was to evaluate the efficacy of combining liraglutide with intragastric balloon. METHODS: Initially, demographic data of patients such as age, gender, comorbid diseases, adverse events, initial weight, height, body mass index, percent body fat, and waist-hip ratio were collected. Weight, body mass index, percent body fat, and waist-hip ratio were measured in the second, third, fourth, fifth, and sixth months. Then, intragastric balloon was removed and liraglutide was stopped. RESULTS: A total of 50 patients were included in the study, of whom 28 (56%) were in Group A (intragastric balloon) and 22 (44%) were in Group B (plus liraglutide). Weight change at the time of balloon removal was higher in Group B [median weight change 13.8 (7.8 min to 16.8 max) versus 7.9 (4.8 min to 11.8 max); p<0.01]. When the weight, percent body fat, body mass index, and waist-hip ratio changes were compared according to gender, no significant difference was observed in the groups. Comorbid diseases were hypertension in 7 patients (4 in Group A and 3 in Group B) and diabetes in 9 patients (5 in Group A and 4 in Group B). No statistical significance was found. CONCLUSION: Liraglutide has benefits in terms of weight, percent body fat, and body mass index reduction when administered with intragastric balloon.

SUMMARY OBJECTIVE: The objective of this study was to evaluate the correlation between clinical and serological findings of pregnant women and newborns with patterns of histopathologic changes of the placenta diagnosed with coronavirus disease 2019. METHODS: A prospective descriptive study was conducted with pregnant women who were positive for SARS-CoV-2 by reverse transcription polymerase chain reaction or serology (IgG and IgM). Clinical analyses were performed using ELISA to detect anti-SARS-CoV-2 IgG and IgA antibodies using the S1 spike protein domain with the Euroimmun kit. Histopathologic analyses of placentas were performed by two expert pathologists. RESULTS: Maternal SARS-CoV-2 infection was associated with increased neonatal hospital length of stay (p=0.03), increased preterm birth (p=0.04), and Apgar score<7 at 1st min (p=0.00) and 5th min (p=0.02). Pregnant women with positive IgG and/or IgA at delivery had a higher incidence of placental histopathologic changes in addition to a greater likelihood of having an IgG-positive fetus (p<0.0001). Placentas with positive reverse transcription polymerase chain reaction for SARS-CoV-2 had a higher incidence of histopathologic changes such as maternal vascular hypoperfusion changes (p=0.00). CONCLUSION: Maternal SARS-CoV-2 infection was associated with adverse perinatal outcomes. Pregnant women with positive IgG at delivery had a higher incidence of placental histopathologic changes. Placentas with positive reverse transcription polymerase chain reaction for SARS-CoV-2 had a higher incidence of histopathologic changes such as maternal vascular hypoperfusion.

SUMMARY OBJECTIVE: The aim of this study was to demonstrate the effect of myofascial pain with referral from the trigger points in the masseter muscles on the clinical symptoms and functional limitations of the temporomandibular joint in participants with disc displacement with reduction. METHODS: This prospective, cross-sectional study recruited participants aged 18–45 years with disc displacement with reduction with/without myofascial pain with referral in the masseter muscles based on the inclusion criteria. Maximum mouth opening and the presence of probable awake bruxism were assessed. The “Graded Chronic Pain Scale version 2.0” and “Jaw Function Limitation Scale-8” were used to evaluate Diagnostic Criteria for Temporomandibular Disorders Axis II. Pain levels were measured using the Visual Analog Scale. RESULTS: A comparison between the disc displacement with reduction and disc displacement with reduction+myofascial pain with referral groups revealed statistically significant differences in Visual Analog Scale (p<0.001), the presence of awake bruxism (p=0.038), and Graded Chronic Pain Scale version 2.0 (p=0.010). However, no statistically significant difference was observed between the two groups concerning maximum mouth opening and Jaw Function Limitation Scale-8. CONCLUSION: Participants with both disc displacement with reduction and myofascial pain with referral in the masseter muscle exhibited higher pain intensity, a higher prevalence of awake bruxism, and increased pain-related disability compared to those with disc displacement with reduction alone.

SUMMARY OBJECTIVE: This study aimed to evaluate the relationship between the toxicity of cyclin-dependent kinase 4/6 inhibitors and body mass index and body surface area. METHODS: A total of 83 patients were included in the study. Patients were divided into 4 groups as 18–24.9, 25–29.9, 30–39.9, and >40 kg/m2 according to body mass index and into two groups as below and above 1.77 according to body surface area. The relationship between body mass index and body surface area and side effects was evaluated. RESULTS: No statistically significant difference was found between body mass index groups and side effects. Grade 3 neutropenia was more common in patients on palbociclib with a body surface area≤1.77. In our study, it was revealed that less hematological side effects can be encountered when body surface area is taken into account.

SUMMARY OBJECTIVE: While the literature contains several studies on the frailty assessed during hospitalization and/or outpatient settings and nursing homes, few studies have assessed frailty in community-dwelling older adults. We investigated the prevalence of frailty and associated factors among older adults in a sample of community-dwelling older adults. METHODS: We included community-dwelling older adults >60 years living in the Fatih District of the Istanbul Province. We conducted the study between November 2014 and May 2015. We collected the data such as age, sex, number of diseases and drugs, functional status, frailty, the presence of geriatric syndromes, common diseases, and quality-of-life assessment. Frailty was evaluated by the FRAIL scale. RESULTS: A total of 204 adults (mean age: 75.4±7.3 years) were included, of whom 30.4% were robust, 42.6% were pre-frail, and 27% were frail. In multivariate analyses, associated factors of frailty were the number of drugs [odds ratio (OR)=1.240, p=0.036], the presence of cognitive impairment (OR=0.300, p=0.016), and falls (OR=1.984, p=0.048). CONCLUSION: The present study established the prevalence of frailty in a large district in the largest metropolis in the country through a valid screening method. Our results suggest that clinicians should consider frailty evaluation in patients with multiple drug usage, cognitive impairment, and falls.

SUMMARY BACKGROUND/INTRODUCTION: Heart failure patients with reduced ejection fraction are at high risk for ventricular arrhythmias and sudden cardiac death. Ivabradine, a specific inhibitor of the If current in the sinoatrial node, provides heart rate reduction in sinus rhythm and angina control in chronic coronary syndromes. OBJECTIVE: The effect of ivabradine on ventricular arrhythmias in heart failure patients with reduced ejection fraction patients has not been fully elucidated. The aim of this study was to investigate the effect of ivabradine use on life-threatening arrhythmias and long-term mortality in heart failure patients with reduced ejection fraction patients. METHODS: In this retrospective study, 1,639 patients with heart failure patients with reduced ejection fraction were included. Patients were divided into two groups: ivabradine users and nonusers. Patients presenting with ventricular tachycardia, the presence of ventricular extrasystole, and ventricular tachycardia in 24-h rhythm monitoring, appropriate implantable cardioverter-defibrillator shocks, and long-term mortality outcomes were evaluated according to ivabradine use. RESULTS: After adjustment for all possible variables, admission with ventricular tachycardia was three times higher in ivabradine nonusers (95% confidence interval 1.5–10.2). The presence of premature ventricular contractions and ventricular tachycardias in 24-h rhythm Holter monitoring was notably higher in ivabradine nonusers. According to the adjusted model for all variables, 4.1 times more appropriate implantable cardioverter-defibrillator shocks were observed in the ivabradine nonusers than the users (95%CI 1.8–9.6). Long-term mortality did not differ between these groups after adjustment for all covariates. CONCLUSION: The use of ivabradine reduced the appropriate implantable cardioverter-defibrillator discharge in heart failure patients with reduced ejection fraction patients. Ivabradine has potential in the treatment of ventricular arrhythmias in heart failure patients with reduced ejection fraction patients.

SUMMARY OBJECTIVE: The delayed increase in serum creatinine levels poses challenges in the timely diagnosis of acute kidney injury. This study aimed to investigate the relationship between serum angiotensinogen and urinary angiotensinogen levels and the prognosis of renal function in patients diagnosed with acute kidney injury. METHODS: A total of 79 newly diagnosed acute kidney injury patients aged 18 years and older were enrolled. Serum angiotensinogen and urinary angiotensinogen levels were measured at the onset of the disease, as well as on the 15th and 30th days of follow-up. After 3 months, renal function was evaluated by measuring serum creatinine levels. RESULTS: Among the acute kidney injury patients, those in Kidney Disease: Improving Global Outcomes stage 3 exhibited significantly higher urinary angiotensinogen/urine creatinine levels compared with stages 1 and 2 patients at the time of diagnosis (p<0.05). Furthermore, a positive correlation was observed between the urinary angiotensinogen/urine creatinine level at the time of diagnosis and the serum creatinine level at the third month (r=0.408, p=0.048). CONCLUSION: The findings suggest that urinary angiotensinogen levels can serve as an indicator of the severity of acute kidney injury. Monitoring urinary angiotensinogen levels could potentially contribute to the prognosis assessment and management of acute kidney injury patients.

SUMMARY OBJECTIVE: Pulmonary thromboembolism is a disease with high morbidity and mortality. Various changes occur on the electrocardiogram secondary to pulmonary thromboembolism. The objective of this study was to investigate variations in QT dispersion, Tpeak-Tend duration, and Tpeak-Tend/QT ratio in relation to pulmonary thromboembolism localization and their impacts on 30-day mortality. METHODS: This study was carried out in a tertiary emergency medicine clinic between December 1, 2019 and November 30, 2020. We evaluated correlations between radiological outcomes of patients, QT dispersions, T-wave dispersions, Tpeak-Tend durations, and Tpeak-Tend/QT ratios. We sought statistically significant disparities between these values, considering the presence or localization of pulmonary thromboembolism. The 30-day mortality in pulmonary thromboembolism-diagnosed patients was reassessed. RESULTS: Electrocardiogramfindings revealed that T-wave dispersion (p<0.001), Tpeak-Tend duration (p=0.034), and Tpeak-Tend/corrected QT ratio (p=0.003) were lower in patients than controls. Conversely, QT dispersion (p=0.005) and corrected QT dispersion (p<0.001) were higher in patients. CONCLUSION: Electrocardiogram findings such as T-wave dispersion, QT duration, Tpeak-Tend time, and Tpeak-Tend/corrected QT ratio can detect pulmonary thromboembolism. More studies with larger cohorts are required to further understand the role of QT and corrected QT dispersion in pulmonary thromboembolism patient mortality.

SUMMARY OBJECTIVE: The aim of this study was to analyze the surgical content of the 50 most-viewed laparoscopic myomectomy videos on YouTube while evaluating the educational quality and accuracy of the videos. METHODS: In this cross-sectional study, the keyword “laparoscopic myomectomy” was searched in publicly available content on YouTube, and the videos were sorted by view count using YouTube's advanced search options. Out of the first 66 videos, only 50 were eligible according to our selection criteria. One associate professor of gynecology and one gynecology resident watched these videos independently and evaluated the quality and surgical aspects. Our primary outcome was the scores of the Quality Criteria for Consumer Health Information and Global Quality Score and the features of the surgical technique. RESULTS: The 50 most-viewed laparoscopic myomectomy videos were uploaded between 2010 and 2021. They had a mean of 66636.6±103772.2 views. According to the Quality Criteria for Consumer Health Information criteria, 78% of the videos were categorized as “poor,” 12% of them were “fair,” and 10% of them were “very poor.” The indication of the surgery was not specified in 27 (54%) of them. The surgeons in 39 (79.6%) of the videos did not use any containment system for the power morcellation, even though it was restricted by the United States Food and Drug Administration. The preoperative and perioperative precautions to minimize blood loss were underemphasized. There was no scientific evidence in 49 (98%) of the videos. CONCLUSION: Laparoscopic myomectomy videos on YouTube are limited in terms of providing evidence-based and well-organized scientific knowledge.

SUMMARY OBJECTIVE: The study aimed to examine the effect of functional independence levels on sleep behavior and constipation in children with cerebral palsy. METHODS: This cross-sectional observational single-center study was carried out in a special rehabilitation center in Istanbul. Inclusion criteria were those aged between 4 and 18 years with Gross Motor Function Classification System III-IV-V functional independence levels. Those who had surgery concerning intestinal health, had a chronic infectious bowel disease, had congenital intestinal anomalies, had received botox treatment in the last 6 months, had uncontrolled epileptic seizures, had complained of constipation in the last 6 months, and had cardiopulmonary disease were excluded from the study. The sociodemographic characteristics of the participants and the Gross Motor Function Classification System were recorded. Pediatric Functional Independence Scale (Functional Independence Measure for Children) was used to measure the functional independence level, Pediatric Sleep Questionnaire was used to measure the level of sleep problems, and Constipation Severity Scale was used to measure constipation severity. RESULTS: A total of 60 children who were diagnosed with cerebral palsy were included. According to Gross Motor Function Classification System, 46.7% of the cases were Level III, 35% were Level IV, and 18.3% were Level V. There was a negative moderate significant correlation between Functional Independence Measure for Children and Pediatric Sleep Questionnaire (r=-0.303; p=0.019) and between Functional Independence Measure for Children and Constipation Severity Scale (r=-0.342; p=0.007). CONCLUSION: We described that lower functional independence levels were related to worse sleep and constipation symptoms. The results suggest that effective strategies for developing functional independence levels may be beneficial for both sleep and constipation symptoms in the concept of cerebral palsy management.

SUMMARY OBJECTIVE: Fetal vascular malperfusion is associated with poor perinatal outcomes in women with preeclampsia and gestational diabetes mellitus. The aim of this study was to determine the association between fetal vascular malperfusion score and syncytiotrophoblast basement membrane thickness and clinicopathological variables, such as developing preeclampsia in women with gestational diabetes mellitus. METHODS: This retrospective cohort study included 65 pregnant participants (34 with gestational diabetes mellitus and 31 controls) between January 2019 and January 2022. Gestational diabetes mellitus was diagnosed as ≥2 of 4 elevated values on a 3-h, 100-g oral glucose tolerance test. The fetal vascular malperfusion score was evaluated by endothelial CD34 positivity in the villous stroma of the placenta. The association between fetal vascular malperfusion score and syncytiotrophoblast basement membrane thickness with clinicopathological variables in women with gestational diabetes mellitus was evaluated. RESULTS: It was revealed that the gestational diabetes mellitus group had greater fetal vascular malperfusion scores than the control group (gestational diabetes mellitus group fetal vascular malperfusion score: 34.2±9.1 and control group fetal vascular malperfusion score: 26.5±8.7, respectively, p=0.0009). Syncytiotrophoblast basement membrane thickness was correlated with the development of preeclampsia, trophoblast proliferation, and fetal vascular malperfusions (0.3952, p=0.0129; 0.3487, p=0.0211; and 0.4331, p=0.0082, respectively). On the contrary, fetal vascular malperfusions were correlated with the development of preeclampsia, villous edema, and trophoblast proliferation (0.3154, p=0.0343; 0.2922, p=0.4123; and 0.3142, p=0.0355, respectively). CONCLUSION: The gestational diabetes mellitus group displayed significantly higher fetal vascular malperfusion scores and thickening of the syncytiotrophoblast basement membrane than the control group. There is a correlation between developing preeclampsia and the fetal vascular malperfusion scores and the syncytiotrophoblast basement membrane thickness.

SUMMARY OBJECTIVE: This prospective randomized study was conducted at Ataturk University Medical Faculty Hospital, Department of Anesthesia and Reanimation, from June 2022 to May 2023. The aim of this study was to compare the effectiveness of ultrasound-guided erector spinae plane block, quadratus lumborum block, and intrathecal morphine to decrease postoperative pain after cesarean section. METHODS: Sixty-term pregnant women who were scheduled for elective cesarean sections with spinal anesthesia were included. Patients were randomly divided into three groups (n=20 for each group): Group 1: Patients were administered intrathecal morphine during spinal anesthesia; Group 2: Patients performed bilateral erector spinae plane block postoperatively; and Group 3: Patients performed bilateral quadratus lumborum block postoperatively. In the postpartum care unit, patients received intravenous Patient-Controlled Analgesia. The Patient-Controlled Analgesia devices were set to administer an intravenous bolus of 25 μg fentanyl, with a lockout interval of 10 min. Opioid consumption and maximum pain score in the 24 postoperative hours were recorded. RESULTS: Patients in Group 1 had a longer time to first analgesic requirement compared to Group 2 (p=0.017). Opioid consumption and resting and moving visual analog score scores in the first 24 h postoperatively were similar between groups. CONCLUSION: All three methods, including intrathecal morphine, erector spinae plane block, and quadratus lumborum block, are efficacious and comparable in providing postoperative analgesia after cesarean under spinal anesthesia.

SUMMARY OBJECTIVE: The Oswestry Disability Index is considered the gold standard in the evaluation of disability in patients with chronic mechanical back pain. The aim of this study was to assess the applicability of Oswestry Disability Index in patients with ankylosing spondylitis and its relationship with disease assessment parameters for ankylosing spondylitis. METHODS: A total of 100 patients diagnosed with ankylosing spondylitis were included in the study group. The control group consisted of 50 individuals with nonspecific low back pain. The Oswestry Disability Index and Bath Ankylosing Spondylitis Disease Activity Index were applied to both groups. In addition, the Visual Analog Scale, the Ankylosing Spondylitis Disease Activity Score C-Reactive Protein, the Ankylosing Spondylitis Disease Activity Score-the Erythrocyte Sedimentation Rate, the Bath Ankylosing Spondylitis Functional Index, Bath Ankylosing Spondylitis Metrology Index, and the Ankylosing Spondylitis Quality of Life scales were applied in the study group. the Erythrocyte Sedimentation Rate, C-Reactive Protein levels, and HLA-B27 analysis were noted as laboratory markers in ankylosing spondylitis patients. RESULTS: The scores of Oswestry Disability Index had a significant correlation with scores of Bath Ankylosing Spondylitis Disease Activity Index in ankylosing spondylitis patients (r=0.543) and in the control group (r=0.401). There was a significant correlation between the scores of Oswestry Disability Index and the Bath Ankylosing Spondylitis Functional Index (r=0.544), Bath Ankylosing Spondylitis Metrology Index (r=0.317), the Ankylosing Spondylitis Quality of Life (r=0.723), the Ankylosing Spondylitis Disease Activity Score-the Erythrocyte Sedimentation Rate (r=0.501), the Ankylosing Spondylitis Disease Activity Score C-Reactive Protein (r=0.530), Visual Analog Scale-Rest (r=0.476), and Visual Analog Scale-Activity (r=0.441) values in patients with ankylosing spondylitis. CONCLUSION: Evaluation of Oswestry Disability Index in conjunction with Bath Ankylosing Spondylitis Disease Activity Index may warn the physician to interpret high Bath Ankylosing Spondylitis Disease Activity Index scores in the context of mechanical pain. Therefore, the use of Oswestry Disability Index in patients with ankylosing spondylitis will be beneficial.

SUMMARY OBJECTIVE: Multiple sclerosis is an autoimmune disease that commonly affects the cervical part of the spinal cord. The aim of this study was to evaluate the relationship between cervical spinal cord atrophy and clinical disability in multiple sclerosis patients. METHODS: We examined the cervical spinal cord area measurements of 64 multiple sclerosis patients and 64 healthy control groups over the images obtained by a T2-weighted magnetic resonance imaging device. RESULTS: The C2-3, C3-4, C4-5, and C6-7 axial cross-sectional surface area values of the patient group were statistically lower than those of the control group (p<0.05). A negative correlation was found between patients’ Expanded Disability Status Scale scores and C4-5, C5-6, and C6-7 axial area (axial area p<0.05; r1=-0.472, r2=-0.513, and r3=-0.415). CONCLUSION: When all parameters were evaluated, the data of our control group were found to be higher than the multiple sclerosis groups. There appears to be a significant relationship between patients with cervical spinal cord atrophy and an increase in Expanded Disability Status Scale scores.

SUMMARY OBJECTIVE: This study aimed to increase awareness by determining the risk of obstructive sleep apnea syndrome in individuals aged 18 years and above. METHODS: The study is a descriptive and cross-sectional study. A total of 633 individuals aged 18 years and above participated in the study. The data were collected online from individuals in the form of describing the demographic characteristics of individuals and with the Berlin survey. The IBM SPSS statistics 26.0 program was used in the analysis of the data. RESULTS: In this study, 38.9% of individuals were found to be at high risk for obstructive sleep apnea syndrome. A significant relationship was found between the risk of obstructive sleep apnea syndrome and gender, age, body mass index, education level, chronic obstructive pulmonary disease, diabetes, hypertension, presence of cardiovascular diseases, and smoking (p<0.05). CONCLUSION: The results of this study showed that male gender, increasing age, obesity, presence of chronic disease, and smoking increase the risk of obstructive sleep apnea syndrome. Defining the risk of obstructive sleep apnea syndrome, especially in risky groups, will be effective in planning health care, increasing the effectiveness of treatment, and improving the quality of life. It is recommended to include this diagnosis in health care protocols and to expand its use in order to plan and repeat trainings that will emphasize its importance.

SUMMARY OBJECTIVE: Endometriosis is a common chronic inflammatory disease associated with infertility and pelvic pain. Diagnosis is based on the appearance of endometriotic lesions at the time of surgery. Our study aimed to determine whether cystatin C can be used as a predictor of endometriosis and to investigate its potential role in doing so. METHODS: The study included 45 patients with endometriosis between the ages of 18 and 40 years whose pathology results were compatible with endometriosis and were operated on, and a control group of 45 healthy women. These two groups were compared in terms of serum cystatin C levels, demographic-clinical characteristics, operation results, and other laboratory values. RESULTS: The cystatin C and hs-CRP levels of the endometriosis patients were found to be significantly higher than the control subjects (p<0.005). Whether the endometriosis disease could be detected for serum cystatin C levels was determined by the receiver operating characteristic analysis and the most appropriate positive cutoff value for cystatin C was found to be 5.14 ng/mL (86.7% sensitivity and 77.8% specificity). In the linear regression analysis, it was observed that the probability of endometriosis increased 2.5 times when cystatin C levels increased above the threshold value of 5.14 ng/mL (OR: 2.5; 95%CI 2.24–2.76). CONCLUSION: Our study shows that the serum cystatin C levels can be used as a guide for diagnosis in patients with advanced endometriosis. However, more research is needed to prove its reliability and accuracy in order to put it into practice.

SUMMARY OBJECTIVE: The objective of this study was to evaluate the minimum number of required cases for successful robotic retroperitoneal partial nephrectomy for an experienced surgeon in transperitoneal robotic surgery. METHODS: Our prospectively collected clinic database was evaluated retrospectively, and 50 patients who underwent robotic retroperitoneal partial nephrectomy by a single experienced surgeon from January 2019 to February 2023 were included in this study. Demographic and perioperative data and R.E.N.A.L. nephrometry scores were noted. margin, ischemia, and complication score was used to predict surgical success. Receiver operating characteristic curve analysis was used to determine how many cases were required to achieve margin, ischemia, and complication score positivity and to apply the off-clamp technique. Also, the first 25 patients were assigned to Group 1 and the second 25 patients to Group 2, and the data were compared between the groups. RESULTS: The patients’ demographic data and tumor characteristics were similar in the groups. The off-clamp technique and sutureless technique rates in Group 2 were significantly higher than that in Group 1. Margin, ischemia, and complication score positivity was observed in 60% (n=15) of Group 1 and 96% (n=24) of Group 2. At receiver operating characteristic curve analysis, the 25th and later cases were statistically significant in terms of margin, ischemia, and complication score positivity. In terms of performing surgery with the off-clamp technique, the 28th and subsequent cases were statistically significant. CONCLUSION: A total of 25 or more cases appear to be sufficient to provide optimal surgical results in robotic retroperitoneal partial nephrectomy for an experienced surgeon.

SUMMARY OBJECTIVE: Because of the coronavirus disease 19 pandemic, studies on vaccination are being conducted in our country as well as across the world. In this study, the antibody levels in healthcare workers vaccinated with two doses of inactivated vaccine and the factors affecting these levels were investigated. METHODS: Randomly selected volunteers from healthcare workers, who had been vaccinated with two doses of inactivated vaccine in January to February 2021, were included in the study. Blood samples were drawn twice, 1 month and 6 months after the second dose vaccine (CoronaVac:Sinovac Life Science Co, Ltd, Beijing, China). The antibody levels were determined by the chemiluminescence microparticle immunoassay method using kits for quantitative detection of immunoglobulin class G antibodies to severe acute respiratory syndrome coronavirus 2. RESULTS: The mean antibody levels of 129 volunteers were 1232.5 (min: 103 to max: 7151) AU/mL in the first month and 403.5 (min: 23 to max: 4963) AU/mL in the sixth month. According to the survey results, 91 (71%) volunteers had not been diagnosed with coronavirus disease 19 before vaccination. The antibody levels 1 month and 6 months after the second dose of vaccination were significantly higher in those who had been diagnosed with coronavirus disease 19 before vaccination than in those who had not. It was found that age, gender, fast food, or healthy nutrition had no effect on antibody levels. CONCLUSION: Vaccines are very important both to protect against coronavirus disease 19 and to experience only a mild form of the disease. Immunoglobulin class G levels formed after vaccination may be affected by many factors and may decrease over time.

SUMMARY BACKGROUND: Investigation of syncope involves the use of electrophysiological study, particularly in patients with cardiac conduction disorder. There is conflicting evidence about the role of electrophysiological study in patients with Chagas disease. OBJECTIVE: The objective of this study was to evaluate the electrophysiological study findings in patients with Chagas disease and bundle branch block and/or divisional block presenting with syncope. METHODS: This is a retrospective study of patients with Chagas disease and cardiac conduction disorder who underwent electrophysiological study from 2017 to 2021 for the investigation of syncope in a tertiary hospital in São Paulo, Brazil. Those with non-interpretable ECG, known coronary artery disease, and/or other cardiomyopathies were excluded. HV interval and electrophysiological study-induced malignant ventricular arrhythmias data were analyzed. RESULTS: A total of 45 patients (60.2±11.29 years, 57.8% males) were included. The mean HV interval was 58.37 ms±10.68; 22.2% of the studied population presented an HV interval of ≥70 ms; and malignant ventricular arrhythmias were induced in 57.8% patients. The use of beta-blockers and amiodarone (p=0.002 and 0.036, respectively), NYHA functional class≥II (p=0.013), wide QRS (p=0.047), increased HV interval (p=0.02), Rassi score >6.5 (p=0.003), and reduced left ventricular ejection fraction (p=0.031) were associated with increased risk of inducible malignant ventricular arrhythmias. CONCLUSION: More than half of the patients with Chagas disease, syncope, and cardiac conduction disorder have inducible malignant ventricular arrhythmias. Prolonged HV interval was observed in only 20% of population. Wide QRS, prolonged HV, reduced ejection fraction, and higher Rassi score were associated with increased risk of malignant ventricular arrhythmias.

SUMMARY BACKGROUND: Breast cancer is a public health problem with both high incidence and cure rates. After treatment, patients are monitored for long periods of time due to the risk of recurrence. Thus, staging and follow-up strategies should consider not only the best results for the patient but also its costs for the public health system. OBJECTIVE: The objective of this study was to quantify the waste of resources on breast cancer follow-up and evaluate its impact on the public health system. METHODS: This is a retrospective analysis of consecutive medical records to identify the intervals between consultations and tests used for staging and during the first 2 years of follow-up of patients with breast cancer treated at a public hospital in Brazil. Data were compared with the guidelines of the main international consensus. RESULTS: Medical records of 60 consecutive patients treated in 2018 were selected, of whom 52 had 2 or more years of follow-up, and 8 had only 1 year of complete follow-up. A total of 34 patients (56.67%) underwent excessive examinations for stating. During follow-up, 125 surplus consultations were performed (33.6%). In this phase, 111 surplus exams were also performed, representing an increase of 100.9%. A total of 423 laboratory tests were performed for 18 patients in the first year and 229 tests for 14 patients in the second year. CONCLUSION: Excessive tests and consultations significantly burdened the Unified Health System without any benefit to patients. Better adherence to staging and follow-up recommendations could reduce costs and optimize the limited resources used in the public health system.

SUMMARY OBJECTIVE: Regular exercise benefits health by increasing the body's antioxidant defenses. However, excessive exercise can produce excessive reactive oxygen species, which can lead to oxidative stress. Superoxide dismutase is the primary enzyme involved in the elimination of reactive oxygen species. This study aimed to determine the relationship between the SOD1 gene insertion/deletion variant and elite athletes. METHODS: A total of 305 subjects, including 165 elite athletes from different branches and 140 sedentary individuals, participated in this study. The SOD1 insertion/deletion variant was genotyped using polymerase chain reaction. The results were evaluated statistically. RESULTS: There was no statistical significance between the athletes and control groups in terms of SOD1 insertion/deletion genotype distribution and allele frequency. Then, we evaluated the groups as females and males. There were no female athletes carrying the D/D genotype. The SOD1 I/I genotype and the I allele were more prevalent in female athletes than in the control group. There was a significant difference in terms of SOD1 I/I: I/D+D/D in females (p=0.028). SOD1 genotype and allele distribution did not differ between male athletes and male controls. CONCLUSION: As far as we know, this is the first study to evaluate the SOD1 insertion/deletion variant in athletes in Turkey. Our results showed that the SOD1 I allele was more common in female athletes, but not in male athletes.
