    SUMMARY OBJECTIVE: Nonalcoholic fatty liver disease is a chronic liver disease and a growing global epidemic. The aim of this study was to investigate the association between a visfatin gene (NAMPT) variant and nonalcoholic fatty liver disease, owing to the connection between this disease and insulin resistance, obesity, inflammation, and oxidative stress, and the role of visfatin in these metabolic disorders. METHODS: In the present case-control study, we enrolled 312 genetically unrelated individuals, including 154 patients with biopsy-proven nonalcoholic fatty liver disease and 158 controls. The rs2058539 polymorphism of NAMPT gene was genotyped using the PCR-RFLP method. RESULTS: Genotype and allele distributions of NAMPT gene rs2058539 polymorphism conformed to the Hardy-Weinberg equilibrium both in the case and control groups (p>0.05). The distribution of NAMPT rs2058539 genotypes and alleles differed significantly between the cases with nonalcoholic fatty liver disease and controls. The "CC" genotype of the NAMPT rs2058539 compared with "AA" genotype was associated with a 2.5-fold increased risk of nonalcoholic fatty liver disease after adjustment for confounding factors [p=0.034; odds ratio (OR)=2.52, 95% confidence interval (CI)=1.36–4.37]. Moreover, the NAMPT rs2058539 "C" allele was significantly overrepresented in the nonalcoholic fatty liver disease patients than controls (p=0.022; OR=1.77, 95%CI=1.14–2.31). CONCLUSION: Our findings indicated for the first time that the NAMPT rs2058539 "CC" genotype is a marker of increased nonalcoholic fatty liver disease susceptibility; however, it needs to be supported by further investigations in other populations.

    Alyousif, Sihad Salim Hakeem; Ozbakir, Burcu; Ozay, Ali Cenk; Tulay, Pinar

    Resumo em Inglês:

    SUMMARY OBJECTIVE: The objective of this study was to investigate the allele frequencies of polymorphisms in genes CYP11A1 rs4886595 and CYP11A1 rs4887139 that are responsible for the steroidogenesis mechanism in polycystic ovary syndrome patients and control females. METHODS: Samples were obtained from the Department of Obstetrics and Gynecology in the Near East University Hospital from September 2019 to December 2019. Only the nonobese patients between the ages of 18–40 years were included in this study following informed consent. Obese patients and patients more than 40 years of age were excluded from the study. Nonobese women and normal ovulation were included in the control group. DNA was isolated from blood samples. Real-time polymerase chain reaction (PCR) was used to analyze single nucleotide polymorphisms (SNPs) in various genes linked to polycystic ovary syndrome. The studies were carried out using the samples obtained from 120 women, of whom 55 were nonobese and had normal ovulation, and 65 were polycystic ovary syndrome patients. The allelic frequencies of SNPs in genes linked to polycystic ovary syndrome were calculated using real-time PCR outcomes. RESULTS: The variation of the CYP11A1 rs4887139 G>A did not show any significance, while the variation of CYP11A1 rs4886595 C>A showed significant differences between the patient and the control groups (p=0.01), respectively. CONCLUSION: Future research ought to focus on elucidating the susceptible causes of polycystic ovary syndrome with a wide range of SNPs and more sample size. The genome-wide association studies in polycystic ovary syndrome patients of different origin will be important to identify candidate genes as well as proteins that are implied in polycystic ovary syndrome risk.

    Silva, Douglas Inomata Cardoso da; Ishimoto, Letícia Yumi; Franco, Estefânia Aparecida Thomé; Santos, Maércio Souza Cícero dos; Brizola, Luís Fernando Pereira; Colombo, Camila Aparecida; Savadkouhi, Edris Guardiano; Machado, Luiz Henrique Soares; Tanni, Suzana Erico; Prudente, Robson

    Resumo em Inglês:

    SUMMARY OBJECTIVE: The aim of this study was to evaluate the efficacy of long-term oxygen therapy as a strategy to reduce hospitalization time in patients affected by COVID-19. METHODS: Between April and December 2021, COVID-19 patients with stable clinical conditions needing supplementary oxygen therapy during hospitalization were oriented to have hospital discharge with long-term oxygen therapy and reassessment after 15 days. RESULTS: A total of 62 patients were evaluated and, 15 days after discharge, 69% of patients had suspended long-term oxygen therapy, with no difference between the groups admitted to the intensive care unit or the ward (p=0.319). Among the individuals who needed to maintain long-term oxygen therapy, in addition to worse P/F ratio (265±57 vs. 345±51; p<0.001) and lower partial pressure of oxygen (55±12 vs. 72±11 mmHg; p<0.001), were those more obese (37±8 vs. 30±6 kg/m2; p=0.032), needed more time for invasive mechanical ventilation (46±27 vs. 20±16 days; p=0.029), had greater persistence of symptoms (p<0.001), and shorter time between the onset of symptoms and the need for hospitalization (7 [2–9] vs. 10 [6–12] days; p=0.039). CONCLUSION: Long-term oxygen therapy is an effective strategy for reducing hospitalization time in COVID-19 patients, regardless of gravity. Additionally, more obese patients with persistence of respiratory symptoms, faster disease evolution, and more days of invasive mechanical ventilation needed to maintain the long-term oxygen therapy longer.
  • Association between nonalcoholic steatohepatitis and high serum ferritin levels in type 2 diabetes mellitus Original Article

    Wang, Tong; He, Le; Wang, Shaoxin; Ma, Dequan

    Resumo em Inglês:

    SUMMARY OBJECTIVE: The aim of this study was to assess the role of elevated serum ferritin levels in the onset, pathological progression and prognosis of nonalcoholic fatty liver disease. Nonalcoholic fatty liver disease has been rapidly increasing worldwide. Despite extensive research on the pathogenesis of nonalcoholic fatty liver disease, a lack of sufficient clinical research on the relationship between nonalcoholic fatty liver disease and serum ferritin levels remains. METHODS: We analysed 968 patients with type 2 diabetes mellitus who underwent liver ultrasound examination and had their serum ferritin levels measured. The presence of nonalcoholic fatty liver disease and advanced liver fibrosis was determined through abdominal ultrasound examination and the nonalcoholic fatty liver disease fibrosis score. RESULTS: Compared to that in the non-nonalcoholic fatty liver disease group, the presence of hyperferritinemia was significantly more common in the nonalcoholic fatty liver disease group (83.3 vs. 56.3%, p=0.005). When patients with nonalcoholic fatty liver disease were stratified by the nonalcoholic fatty liver disease fibrosis score, those with advanced liver fibrosis exhibited a higher prevalence of hyperferritinemia (56.3, 78.9, and 88.9% for none, simple steatosis, and advanced fibrosis, respectively; p for trend=0.002). In multivariate logistic regression, liver fibrosis was independently associated with hyperferritinemia (odds ratio [OR] 1.45; 95% confidence interval [CI] 1.18–2.02; p=0.014), and this association remained significant in male patients after adjusting for other risk factors (OR 2.66; 95% CI 1.43–5.48; p=0.026). CONCLUSION: Identifying nonalcoholic fatty liver disease patients at a risk of developing nonalcoholic steatohepatitis and advanced fibrosis is crucial for implementing timely interventions and improving patient outcomes. This study highlights the potential utility of serum ferritin levels as a serum biomarker for identifying nonalcoholic steatohepatitis patients and those at a risk of late-stage fibrosis, particularly in male patients with nonalcoholic fatty liver disease.

    Carlstron, Pedro Teodoro; Augusto, Marina Nóbrega; Peixoto, Alberto Borges; Araujo Júnior, Edward; Mello, Nathalia; Mattar, Rosiane; Sun, Sue Yazaki

    Resumo em Inglês:

    SUMMARY OBJECTIVE: The aim of this study was to evaluate the impact of therapeutic hypothermia on maternal and perinatal outcomes in newborns with Apgar score<7 at the 5th min. METHODS: A retrospective cohort study was carried out with 55 newborns who had an Apgar score<7 at the 5th min (35 without and 20 with therapeutic hypothermia) from low-risk pregnancies between 33 and 41 weeks gestation. The Apgar score was calculated through an objective assessment by a neonatologist in the delivery room. Therapeutic hypothermia was indicated by a neonatologist in the delivery room, according to the protocol established by the Brazilian Society of Pediatrics. The maternal and perinatal outcomes of both groups (without and with therapeutic hypothermia) were compared. RESULTS: A rate of Apgar score<7 at the 5th min was 1.02%. No statistical differences were observed between the two groups (without and with therapeutic hypothermia) regarding maternal/perinatal complications. The presence of maternal/perinatal complications did not increase the odds ratio of neonatal therapeutic hypothermia in newborns with Apgar score<7 at the 5th min. CONCLUSION: The rate of Apgar score<7 at the 5th min was low, and it was not associated with any maternal/perinatal complications. There was no significant difference in maternal/perinatal complications between newborns who received therapeutic hypothermia and those who did not.
  • The rs1862513 promoter variant of resistin gene influences susceptibility to nonalcoholic fatty liver disease Original Article

    Nouri, Shadi; Navari, Mahsa; Shafiee, Radmehr; Mahmoudi, Touraj; Rezamand, Gholamreza; Asadi, Asadollah; Nobakht, Hossein; Dabiri, Reza; Farahani, Hamid; Tabaeian, Seidamir Pasha

    Resumo em Inglês:

    SUMMARY OBJECTIVES: Nonalcoholic fatty liver disease is the term used for a range of conditions in which fat builds up in the liver and exceeds 5% of hepatocytes without inordinate alcohol intake or other causes of lipid accumulation. Regarding the fact that insulin resistance and obesity play key roles in the pathogenesis of nonalcoholic fatty liver disease, as well as the connection between resistin and these metabolic diseases, the association between nonalcoholic fatty liver disease and a resistin gene (RETN) polymorphism was examined. METHODS: In this genetic case–control association study, 150 biopsy-proven nonalcoholic fatty liver disease patients and 154 controls were enrolled and genotyped for the RETN rs1862513 (-420C>G) gene polymorphism using PCR–RFLP method. RESULTS: The −420C>G genotype frequency distributions in both groups were consistent with Hardy-Weinberg equilibrium (HWE; p>0.05). The carriers of the RETN −420C>G "CC" genotype compared with the "GG" genotype occurred less frequently in the cases with nonalcoholic fatty liver disease than in the controls, and the difference remained significant even after adjustment for confounding factors (p=0.030; OR=0.47, 95%CI=0.36–0.93). Interestingly, the RETN −420C>G "C" allele was also associated with a decreased risk for nonalcoholic fatty liver disease too (p=0.042; OR=0.72, 95%CI=0.53–0.95). CONCLUSION: We found for the first time an association between biopsy-proven nonalcoholic fatty liver disease and RETN −420C>G promoter polymorphism. The carriers of the RETN −420C>G "CC" genotype had a 53% decreased risk for nonalcoholic fatty liver disease. Our findings, however, need to be corroborated by further studies.
  • A new effect of intravenous iron treatment in pregnancy: contraction in nonstress test and timing of labor Original Article

    Halilzade, Mohammad İbrahim; Halilzade, İnci; Kokanalı, Mahmut Kuntay

    Resumo em Inglês:

    SUMMARY OBJECTIVE: The aim of this study was to elucidate the cause and results of contractions occurring in term pregnant women receiving intravenous iron therapy. METHODS: During 2019–2020, 136 pregnant women beyond 35 weeks of gestation, who received intravenous iron treatment due to iron deficiency anemia, were included through retrospective screening. Iron deficiency anemia was defined as having hemoglobin levels <10 g/dL and ferritin levels <15 ng/mL, and the pregnant women underwent nonstress test before and after treatment. RESULTS: The average treatment week for the pregnant women was 36.82±0.74, and the presence of regular contractions in post-treatment follow-up nonstress tests was 72.1% (n=98). The average week of birth was 38.48±1.60. Pregnant women with contractions who had previous cesarean were found to have a mean delivery week of 36.82±0.67, which was statistically significant earlier than for nulliparous and multiparous women (p<0.001). Conclusion: In pregnant women with iron deficiency anemia who were beyond 35 weeks, temporary regular contractions may be observed in the nonstress test following intravenous iron replacement. We think that this effect may lead to early term birth in pregnant women with a history of cesarean section. It needs to be confirmed by further prospective studies and animal studies.

    Ergani, Seval Yılmaz; İbanoğlu, Müjde Can; Çakır, Ayberk; Ateş, Çağlayan; Örgül, Gökcen; Tonyalı, Nazan Vanlı; Çelik, Özge Yücel; Şahin, Dilek

    Resumo em Inglês:

    SUMMARY OBJECTIVE: We aimed to compare the etiology and perinatal outcomes of non-immune hydrops fetalis diagnosed early- and late-onset at our hospital. METHODS: The records of the patients who applied to our department were reviewed, and we reached 42 non-immune hydrops fetalis cases retrospectively and examined the medical records. Hydrops diagnosis week, birth week, accompanying anomalies, and perinatal outcomes were compared as ≤12 weeks (early-onset) and >12 weeks (late-onset). RESULTS: The prevalence of non-immune hydrops fetalis was 0.05%, and the median week of diagnosis for hydrops was 18 weeks. Consanguinity (16.7%) was found in seven pregnancies, and the other seven patients (16.7%) had a history of hydrops in previous pregnancies. Anomalies of the skeletal system, central nervous system, and gastrointestinal tract accounted for 66.7% of ≤12 weeks in non-immune hydrops fetalis cases. Cardiac abnormalities were more common (26.7%) in patients at > 12 weeks (p=0.078). A statistically significant difference was found between the distribution of week of birth and week of diagnosis (p=0.029). Notably, 66.7% of patients diagnosed before week 12 and 23.3% of patients diagnosed after week 12 delivered their babies before week 24. Spontaneous intrauterine death occurred before week 12 in 45.5% (n=5) of non-immune hydrops fetalis and after week 12 in 39.1% (n=9) of non-immune hydrops fetalis. Notably, 69.2% (n=9) of the patients who had prenatal invasive testing resulted in normal karyotype. CONCLUSION: In this study, most of the fetuses diagnosed with early-onset non-immune hydrops fetalis were born in the first 24 weeks. Additionally, live birth rates and cardiac anomalies were observed to be higher in late-onset non-immune hydrops fetalis.
  • Determinants of health-promoting behaviors in pregnant women Original Article

    Bektemur, Guven; Keles, Esra; Kaya, Leyla; Baydili, Kurşad Nuri

    Resumo em Inglês:

    SUMMARY OBJECTIVE: The aim of the study was to examine the relationship between social support, marital dissatisfaction, psychological factors, and health-promoting behaviors in pregnant women. METHODS: This cross-sectional study was conducted on 1,265 pregnant women who visited the outpatient clinic of a maternity hospital between May and August 2023. The Health Promotion Lifestyle-II Questionnaire was used to measure the healthy lifestyle behaviors of pregnant women. The mental health status of pregnant women was measured using the Depression Anxiety and Stress Scale-21. The Marital Disaffection Scale was used to assess the level of disaffection toward a spouse. Perceived social support was measured by the Multidimensional Perceived Social Support Scale. RESULTS: Pregnant women had a mean age of 26.46±5.09 years. Multivariate linear regression analysis revealed that there was a positive association between perceived social support and health-promoting behaviors. It was also found that marital disaffection was negatively associated with health-promoting behaviors (p<0.001). CONCLUSION: The present study suggests that stress, anxiety, depression, and marital disaffection are negatively associated with health-promoting lifestyle behaviors, while social support is positively associated with the adoption of health practices in pregnant women. Understanding the complex interplay between psychosocial factors and healthy behaviors is crucial to improving healthy behaviors in pregnant women.

    Bahadir, Kutay; Ural, Selin; Abdullayev, Javid; Karaman, Abdurrahman; Parlak, Mesut; Boz, Adil; Karaguzel, Gungor

    Resumo em Inglês:

    SUMMARY OBJECTIVE: Thyroidectomy is a relatively uncommon procedure in pediatric patients. We aimed to review our 20-year experience of thyroid surgery. METHODS: A total of 39 patients who underwent thyroid surgery from 2003 to 2023 were retrospectively evaluated. All patients were followed preoperatively and postoperatively by our institutional multidisciplinary board. Patients were divided into two groups based on their pathologies: benign and malignant. RESULTS: In total, 39 patients (27 girls and 12 boys) underwent 47 thyroid surgeries (total thyroidectomy in 19 patients and subtotal thyroidectomy in 20 patients, with 8 of them having completion thyroidectomy). Notably, 20 (51%) patients had benign and 19 (49%) patients had malignant pathologies. Median age at operation was 157 (9–223) months in the benign group and 182 (1–213) months in the malignant group. In the benign group, 12 (60%) patients had colloidal goiter and 8 (40%) patients had other conditions. In the malignant group, 12 (63%) patients had papillary thyroid carcinoma, 3 (16%) patients had follicular thyroid carcinoma, 2 (11%) had medullary thyroid carcinoma, and 2 patients had other thyroid malignancies. Overall permanent complication rate was 2 out of 39 (5%), which was similar for both groups (1 hypocalcemia in each group). The median follow-up was 38 months (1–179 months) with no local recurrence or distant metastasis. CONCLUSION: Pediatric thyroidectomies are performed on a heterogeneous group of pediatric patients due to a diverse group of pathologies. A multidisciplinary approach is required for proper initial management and surgical strategy with decreased complication rate and event-free survival of these patients in experienced tertiary centers.
  • Hepatitis B reactivation risk and physician awareness in rheumatological patients receiving anti-tumor necrosis factor-α treatment Original Article

    Cure, Osman; Kizilkaya, Bayram; Durak, Serdar; Ilkkilic, Kadir

    Resumo em Inglês:

    SUMMARY OBJECTIVE: We aimed to evaluate the risk of hepatitis B virus reactivation in rheumatic patients using anti-tumor necrosis factor-alpha drugs and the awareness of physicians about hepatitis B virus reactivation. METHODS: Demographic characteristics, pre- and post-treatment hepatitis markers, and laboratory parameters of patients receiving anti-tumor necrosis factor-alpha therapy in our rheumatology clinic were retrospectively examined. RESULTS: A total of 448 patients, 240 (53.6%) female and 208 (46.4%) male, were evaluated. Their mean age was 48.02±14.64 years. While HBsAg was examined in 443 (98.9%) patients before treatment, 7 (1.6%) patients were found to be HBsAg positive. While anti-HBc IgG was examined in 405 (90.4%) patients, it was positive in 69 (17%) patients. HBs Ag (total 446–99.6%) test was performed in three patients who were not tested for HBsAg before the treatment, and anti-HBc total (431–96.2% total) test was performed in 26 patients who were not tested for anti-HBc total. All HBsAg positive patients and 17 (24.6%) of those with previous hepatitis B received antiviral treatment. While the median follow-up period of the patients was 24 (6–60) months, no patient developed hepatitis B virus reactivation. CONCLUSION: The screening rates and awareness of physicians providing anti-tumor necrosis factor-alpha therapy for hepatitis B virus infection were found to be higher compared to similar studies. Hepatitis B virus reactivation did not develop in any patient. Since the risk of hepatitis B virus reactivation is low, especially in patients with previous hepatitis B, it would be more appropriate to follow up the patients without giving antiviral prophylaxis.

    Vilas-Boas, Letícia Sampaio; Sanches, Marcos Paulo Ribeiro; Araujo Júnior, Edward; Peixoto, Alberto Borges; Mattar, Rosiane; Santos, Leandra Rejane Rodrigues dos; Pares, David Baptista da Silva; Sun, Sue Yasaki

    Resumo em Inglês:

    SUMMARY OBJECTIVE: The aim of this study was to evaluate the success rate and predictors of labor induction using vaginal misoprostol in a low-risk pregnant women population. METHODS: A prospective cohort study was carried out with 196 pregnant women. Groups 2 and 4 of the Robson Classification admitted for induction of labor with vaginal misoprostol (25 μg tablets every 6 h, up to 4 tablets, for a maximum of 24 h). The success of labor induction was considered the achievement of vaginal delivery. Binary logistic regression was used to determine the best predictors of successful induction of labor with vaginal misoprostol. RESULTS: Of all the pregnant women analyzed, 140 (71.4%) were successful and 56 (28.6%) were unsuccessful. Pregnant women who achieved successful induction had a higher number of pregnancies (1.69 vs. 1.36, p=0.023), a higher number of deliveries (0.57 vs. 0.19, p<0.001), a higher Bishop score (2.0 vs. 1.38, p=0.002), and lower misoprostol 25 μg tablets (2.18 vs. 2.57, p=0.031). No previous deliveries [x2(1)=3.14, odds ratio (OR): 0.24, 95% confidence interval (CI): 0.10–0.57, R2 Nagelkerke: 0.91, p=0.001] and the presence of one previous delivery [x2(1)=6.0, OR: 3.40, 95% CI: 1.13–10.16, R2 Nagelkerke: 0.043, p=0.029] were significant predictors of successful induction of labor with vaginal misoprostol. CONCLUSION: A high rate of labor induction success using vaginal misoprostol in a low-risk population was observed, mainly in multiparous and with gestational age>41 weeks. No previous delivery decreased the success of labor induction, while one previous delivery increased the success of labor induction.
  • Investigation of the effect of Myricetin on Cisplatin-induced liver hepatotoxicity Original Article

    Aksoy, Sümeyye; Kuloğlu, Nurhan; Karabulut, Derya; Yakan, Birkan

    Resumo em Inglês:

    SUMMARY OBJECTIVE: Cisplatin, a widely used anticancer agent, induces hepatotoxicity alongside organ damage. Understanding Cisplatin's toxicity mechanism and developing preventive measures are crucial. Our study explores Myricetin, a flavonoid, for its protective effects against Cisplatin-induced hepatotoxicity. METHODS: In our study, a total of 32 Wistar albino male rats were utilized, which were categorized into four distinct groups: Control, Myricetin, Cisplatin, and Myricetin+Cisplatin. For the histological assessment of hepatic tissues, hematoxylin–eosin and periodic acid Schiff staining were employed, alongside immunohistochemical measurements of TNF-α, interleukin-17, and interleukin-6 immunoreactivity. Additionally, aspartate transaminase and alanine transaminase values were examined by biochemical analysis. RESULTS: In the histological evaluation of the tissues, a normal healthy cell structure and a strong periodic acid Schiff (+) reaction were observed in the hepatocyte cells in the tissues of the Control and Myricetin groups, while intense eosinophilia, minimal vacuolization, congestion, and sinusoidal expansions were observed in the hematoxylin–eosin stainings, and a decrease in the positive reaction in the periodic acid Schiff staining was observed in the Cisplatin group. Consistent with these histological findings, an increase in TNF-α, interleukin-17, and interleukin-6 expressions (p<0.0001) and a concomitant increase in aspartate transaminase and alanine transaminase values were observed in the Cisplatin group. In the group protected by Myricetin, a significant improvement was observed in all these histological and biochemical values. CONCLUSION: Cisplatin induces notable histopathological alterations in the liver. In this context, Myricetin exhibits the potential to alleviate Cisplatin-induced damage by modulating histological parameters and biochemical processes.
  • A preliminary study on the association between prognostic nutritional index and neutrophil-to-lymphocyte ratio with nutritional status and inflammation in febrile children's susceptibility to seizures Original Article

    Çetin, İpek Dokurel; Çetin, Orkun

    Resumo em Inglês:

    SUMMARY OBJECTIVE: The aim of this study was to evaluate the association between nutritional status, inflammation, and susceptibility to seizures in febrile children. METHODS: This observational single-center study was carried out from January 2020 to December 2023 with 324 children aged 6 months and 6 years; 106 were diagnosed with febrile seizure, 108 were febrile children, and 110 were healthy controls. The prognostic nutritional index and neutrophil-to-lymphocyte ratio were calculated, and the cutoff threshold was established through receiver operating characteristics. The study utilized correlation and univariate–multivariate logistic regression analysis. The comparison between simple and complex febrile seizure was conducted to analyze differences. RESULTS: The optimal cutoff values were identified as 61.25 for prognostic nutritional index and 1.04 for neutrophil-to-lymphocyte ratio. Our findings showed a significant negative association between febrile seizure and platelet count, high C-reactive protein, and high ferritin levels. Additionally, the febrile seizure group showed a significant positive correlation with high neutrophil-to-lymphocyte ratio values (≥1.04) and body temperature (≥38). Our findings revealed that high neutrophil-to-lymphocyte ratio, high C-reactive protein, and age less than 18 months were independently associated with seizure susceptibility in febrile children. CONCLUSION: High neutrophil-to-lymphocyte ratio values and low prognostic nutritional index scores may serve as novel surrogate independent factors for seizure susceptibility in febrile children. Febrile children who are less than 18 months old are more prone to experience seizures than older febrile children. Moreover, there was a correlation between febrile seizures and elevated C-reactive protein levels and neutrophil-to-lymphocyte ratio values.

    Menekşeoğlu, Ahmet Kıvanç; İş, Enes Efe

    Resumo em Inglês:

    SUMMARY OBJECTİVES: The aim of this study was to compare the performance of artificial intelligence models ChatGPT-3.5, ChatGPT-4, and Google Bard in answering Physical Medicine and Rehabilitation board-style questions, assessing their capabilities in medical education and potential clinical applications. METHODS: A comparative cross-sectional study was conducted using the PMR100, an example question set for the American Board of Physical Medicine and Rehabilitation Part I exam, focusing on artificial intelligence models' ability to answer and categorize questions by difficulty. The study evaluated the artificial intelligence models and analyzed them for accuracy, reliability, and alignment with difficulty levels determined by physiatrists. RESULTS: ChatGPT-4 led with a 74% success rate, followed by Bard at 66%, and ChatGPT-3.5 at 63.8%. Bard showed remarkable answer consistency, altering responses in only 1% of cases. The difficulty assessment by ChatGPT models closely matched that of physiatrists. The study highlighted nuanced differences in artificial intelligence models' performance across various Physical Medicine and Rehabilitation subfields. CONCLUSION: The study illustrates the potential of artificial intelligence in medical education and clinical settings, with ChatGPT-4 showing a slight edge in performance. It emphasizes the importance of artificial intelligence as a supportive tool for physiatrists, despite the need for careful oversight of artificial intelligence-generated responses to ensure patient safety.
  • The effect of serum biochemical parameters on clinical prognosis in children presenting with diabetic ketoacidosis Original Article

    Isik, Gunes; Aydin, Can

    Resumo em Inglês:

    SUMMARY OBJECTIVE: The aim of this study was to determine whether diabetes mellitus has a high risk of diabetic ketoacidosis-related complications. Biochemical parameters affect the resolution time of diabetic ketoacidosis. METHODS: The present study is based on a retrospective evaluation of the records of patients who presented to the Pediatrics Clinic of Adiyaman University Hospital between January 1, 2017, and October 1, 2022, with a diagnosis ofdiabetic ketoacidosis. The demographic characteristics, serum biochemical parameters, blood gas results, and time to transition to subcutaneous insulin therapy were all recorded. RESULTS: This study included 49 (49%) female and 51 (51%) male patients aged 1–17 years (mean age: 9.05±4.33 years). The average time to clinical improvement of the sample, that is, transition to subcutaneous insulin therapy, was 21.04±7.8 h. An evaluation of the presence of acute kidney injury based on serum urea and creatinine levels and eGFR values revealed no significant effect on the rate of clinical recovery (respective p-values: p=0.076, p=0.494, and p=0.884). A univariate analysis identified blood glucose (p=0.025), blood gas pH (p<0.001), and blood bicarbonate (p=0.004) values as prognostic factors, while a multivariate analysis revealed pH values had an independent and significant effect on the resolution time of diabetic ketoacidosis. CONCLUSION: Serum glucose, pH, and bicarbonate levels are the most important determinants of clinical prognosis in patients with diabetic ketoacidosis. These findings can serve as a guide for clinicians in the follow-up and treatment of such patients.

    Cartagena-Ramos, Denisse; Fuentealba-Torres, Miguel; Arroyo, Luiz Henrique; Santos, Daniella Talita dos; Rebustini, Flávio; Lara, Lúcia Alves Silva; Arcêncio, Ricardo Alexandre; Nascimento, Lucila Castanheira

    Resumo em Inglês:

    SUMMARY The Sexual Desire Inventory 2 is a self-report instrument for assessing sexual desire in men and women. In Brazil, there is no validated sexual desire self-report for the adult population. Objective: The aim of this study was to determine the evidence of validity for the content and construct of the Brazilian online version of the Sexual Desire Inventory 2. Methods: This was a cross-sectional study with Brazilian men and women. The sample size was calculated using the criterion of more than 20 participants per item. The invitation to participate in the study was conducted online by the platform Survey Monkey®. The Sexual Desire Inventory 2 was evaluated for content, construct, reliability, and invariance. Results: A total of 818 female and male adults participated in the study. The two-dimensional factorial solution represented 71% of the total variance explained by the model, and the factorial loads of the model were ≥0.40; commonalities presented values ≥0.23. Reliability was measured by the coefficients of Cronbach's alpha with a total score of 0.87, McDonald's of 0.87, Omega, and greatest lower bound with a total score of 0.95. The metric invariance was tested for the sex variables ΔCFI (comparative fit index) and ΔRMSEA (root mean square error of approximation) with a total score of 0.01. Conclusion: The analyses indicate evidence of robust validity in the Brazilian online version of the Sexual Desire Inventory 2.

    Resumo em Inglês:

    SUMMARY OBJECTIVE: The objective of this study was to assess the effectiveness and safety of levosimendan as an alternative treatment for pediatric patients with decompensated heart failure unresponsive to conventional inotropes and to emphasize its role in enhancing cardiovascular stability. METHODS: A total of 15 pediatric patients with decompensated heart failure, stemming from acute fulminant myocarditis (53.3%) and post-congenital heart disease surgery complications (46.7%), received levosimendan. The evaluation focused on adverse effects, respiratory support requirements, and concurrent inotropic medication use during levosimendan treatment. Key cardiovascular parameters were assessed at 0, 6, 12, and 24 h post-levosimendan infusion. RESULTS: Levosimendan administration significantly improved key cardiovascular metrics. Left ventricular ejection fraction increased notably from 45±14.8% to 58±15.6% at 24 h (p<0.001). Systolic and diastolic blood pressures rose significantly, with systolic increasing from 79 (68–90) to 98 (89–109) mmHg and diastolic from 47 (40–57) to 66 (54–76) mmHg by 24 h (p<0.001). Heart rate decreased from 162 (111–175) to 132 (99–148) bpm (p=0.02), and lactate levels significantly decreased from 4.15 (2.3–6.5) to 1.85 (0.8–2.6) mmol/L within 6 h (p<0.001). CONCLUSION: Levosimendan demonstrates its significance in managing pediatric heart failure, indicating its safety and potential to enhance cardiac outcomes by reducing reliance on traditional inotropes.

    Resumo em Inglês:

    SUMMARY OBJECTIVE: It has been determined that adropin has a role in tissue healing. This study aimed to determine the effects of head trauma on the tissues and blood levels of patients admitted to the emergency department. METHODS: The study group was divided into two to compare the adropin level in healthy individuals and patients with head trauma. Blood tests from patients and healthy volunteers were compared using the adropin kit. Adropin levels, Glasgow Coma Scale, and revised scores of trauma patients were recorded and analyzed. RESULTS: All patients in the trauma group had significantly higher adropin levels than the control group. Among these patients, the adropin level of the discharged patients was higher than the others. In addition, patients with high Glasgow Coma Scale and normal blood pressure were found to have higher adropin levels than the others. CONCLUSION: Although adropin cannot make a sharp distinction in determining the prognosis, the increase in its level in trauma patients shows that it triggers a protective mechanism.
