ABSTRACT
SUMMARY: In our study, we aimed to reveal the relationship between the anatomical localizations measured and the Body Mass Index (BMI) in patients scheduled for upper gastrointestinal endoscopy. In this study, anatomical localizations of the hiatal clamp and oesophagogastric junction in 189 female and 137 male patients who applied to the hospital with different gastrointestinal system complaints and underwent esophagogastroduodenoscopy (EGD) were investigated depending on BMI. In addition, the data were compared with the patients' complaints before EGD and the diagnoses they received after EGD. SPSS Statistics 22 (IBM Corp. Turkey) program was used for statistical analysis and p0.05). On the other hand, it was determined that the hiatal clamp distance and the distance of the oesophagogastric junction increased as the height and weight increased (p38. As a result of the study, it can be said that BMI values, hiatal clamp distance and oesophagogastric junction localizations may change in relation to height and weight.
En este estudio, buscamos revelar la relación entre las localizaciones anatómicas y el Índice de Masa Corporal (IMC) en pacientes programados para endoscopía digestiva alta. Se investigaron las localizaciones anatómicas de la pinza hiatal y la unión esofagogástrica en 189 mujeres y 137 hombres que acudieron al hospital con diferentes problemas del sistema gastrointestinal los cuales fueron sometetidos a una esofagogastro- duodenoscopia (EGD) dependiendo del IMC. Además, los datos se compararon con las quejas de los pacientes antes de la EGD y los diagnósticos que recibieron después de la EGD. Se utilizó el programa SPSS Statistics 22 (IBM Corp. Turquía) para el análisis estadístico y el valor de p0,05). Por otro lado, se determinó que la distancia de la pinza hiatal y la unión esofagogástrica aumentaba con la altura y el peso corporal (p38. Como resultado del estudio, se puede decir que los valores de IMC, la distancia de pinzamiento hiatal y las localizaciones de la unión esofagogástrica pueden cambiar en relación con la altura y el peso.

Streptococcus mutans is one of the main factors in formation of cariogenic biofilms. New strategies need to be developed to reduce the formation of cariogenic biofilms. For this purpose, bacterial exopolysaccharides (EPS) could be considered as new agents against biofilms. Therefore, cell-bound (b-EPS) and released exopolysaccharides (r-EPS) were extracted from the strains Apilactobacillus kunkeei K1.10 and Latilactobacillus curvatus Kar.9b isolated from the microbiota of honeybees, and their antibiofilm effects on S. mutans biofilm formation were determined. The highest reduction in biofilm formation was achieved by r-EPS of L. curvatus Kar.9b and A. kunkeei K1.10. Scanning electron micrographs (SEM) showed that r-EPS inhibited biofilm formation by reducing adhesion of S. mutans. To increase the production of r-EPS from A. kunkeei K1.10, the effects of different incubation conditions were also analyzed. The highest EPS production was obtained during 48 h-incubation at 37ºC in a medium containing 1% fructose. r-EPS can be used as a raw material to inhibit cariogenic biofilms. Further studies revealing the detailed structural analysis of r-EPS and the mechanism of action of its antibiofilm effect could be beneficial. Finally, b-EPS and r-EPS from lactic acid bacteria were found to have very different properties in terms of their antibiofilm properties.

OBJECTIVE: The objective of this study was to investigate the breast densities and Breast Imaging-Reporting and Data System scores of patients with polycystic ovary syndrome and normoovulatory women and to determine whether these patients constitute a high-risk population for breast cancer. METHODS: This retrospective case-control study was conducted at our institution between January 2022 and December 2022, involving patients diagnosed with polycystic ovary syndrome. Menstrual periods, hyperandrogenemic findings, and ultrasound reports of the patients were retrieved from our hospital's database. Patients who met at least two of the Rotterdam criteria were included in the polycystic ovary syndrome group. A total of 70 premenopausal patients over the age of 40 years, diagnosed with polycystic ovary syndrome, and 70 normoovulatory women, matched for age and body mass index, were included in the study. The two groups were compared regarding age at menarche, menstrual pattern, gravida, parity, levels of follicle-stimulating hormone, luteinizing hormone, and estradiol, endometrial thickness, breast density category, and Breast Imaging-Reporting and Data System classifications. RESULTS: Patients in the polycystic ovary syndrome group had a higher age at menarche (12.7 vs. 12.3, p=0.006). There was no difference between the gonadotropin levels in both groups. However, the estradiol level was higher in the polycystic ovary syndrome group (p<0.001). There was no statistically significant difference between the two groups in terms of breast density and Breast Imaging-Reporting and Data System scores (p=0.319 and p=0.650, respectively). CONCLUSION: Although we can conclude that the risk of breast malignancy is not increased in patients with polycystic ovary syndrome, the impact of the complex hormonal status of polycystic ovary syndrome on breast cancer remains unclear in the literature.

OBJECTIVE: This study aimed to evaluate maternal and fetal characteristics and factors affecting fetal outcomes in twin pregnancies delivered by cesarean section. METHODS: This was a cross-sectional study in a tertiary care referral hospital. The primary outcome was to ascertain the effects of independent factors on the 1st and 5th minute APGAR scores, neonatal intensive care unit admissions, the need for mechanical ventilation, and neonatal mortality. RESULTS: A total of 453 pregnant women and 906 newborns were included in the analysis. The final logistic regression model revealed that early gestational weeks and neonates <3rd weight percentile at the time of delivery were the most significant predictors of all poor outcome parameters in at least one of the twins (p<0.05). General anesthesia for cesarean section was associated with 1st minute APGAR<7 and the need for mechanical ventilation, and emergency surgery was correlated with the need for mechanical ventilation (p<0.05) in at least one of the twins. CONCLUSION: General anesthesia, emergency surgery, early gestational weeks, and birth weight <3rd weight percentile were strongly associated with poor neonatal outcomes in at least one of the twins delivered by cesarean section.

ABSTRACT
La pandemia de COVID-19 se asocia con resultados mentales negativos en el período posparto temprano. Objetivo. Evaluar la salud mental posparto a largo plazo de las mujeres infectadas con COVID-19 durante el embarazo. Métodos. Estudio transversal en 101 gestantes que dieron a luz en un centro terciario durante la pandemia de COVID-19, entre el 31 de marzo de 2020 y el 30 de noviembre de 2021. Se clasificó a las gestantes en 2 grupos como COVID-19 positivo (grupo de estudio, n=52) y COVID-19 negativo (grupo control, n=49). Se recogieron datos sociodemográficos y obstétricos mediante un cuestionario en los períodos posparto temprano (≤6 meses) y tardío (6 a 18 meses). Se calculó la puntuación del Inventario de Depresión de Beck (IDB) y del Inventario de Ansiedad de Beck (IAB) mediante el análisis de los datos de las participantes. Resultados. La puntuación media del IDB y la tasa de depresión (puntuación del IDB >13) en las pacientes con COVID-19 positivo fueron mayores en el período posparto temprano que en el tardío. Según el análisis de regresión lineal multivariante, existió una correlación significativa entre la puntuación IDB de las pacientes con COVID-19 y el nivel educativo y la situación laboral. Según el mismo análisis, existió una correlación significativa entre la puntuación del IAB de los pacientes con COVID-19 y el apoyo del cónyuge, la relación marital y las enfermedades relacionadas con el nacimiento. Se encontró que las pacientes con COVID-19 positivo y COVID-19 negativo tenían puntuaciones IDB e IAB similares en los periodos postparto temprano (≤6 meses) y tardío (6-18 meses). Además, las tasas de ansiedad y depresión fueron similares en ambos grupos en los mismos períodos posparto. Conclusión. En nuestro estudio, la infección por COVID-19 en el embarazo no tuvo un impacto adicional significativo en la salud mental materna en el posparto a largo plazo.
The COVID-19 pandemic is associated with negative mental outcomes in the early postpartum period. Objective: To assess the long-term postpartum mental health of women infected with COVID-19 during pregnancy. Methods: Cross-sectional study in 101 pregnant women who gave birth in a tertiary center during the COVID-19 pandemic, between March 31, 2020, and November 30, 2021. The pregnant women were classified into 2 groups as COVID-19 positive (study group, n=52) and COVID-19 negative (control group, n=49). Sociodemographic and obstetric data were collected by questionnaire in the early (≤6 months) and late (6-18 months) postpartum periods. Beck Depression Inventory (BDI) and Beck Anxiety Inventory (BAI) scores were calculated by analysis of the participants' data. Results: The mean BDI score and the rate of depression (BDI score >13) in COVID-19 positive patients were higher in the early postpartum period than in the late postpartum period. According to multivariate linear regression analysis, there was a significant correlation between the BDI score of COVID-19 patients and educational level and employment status. According to the same analysis, there was a significant correlation between the BAI score of COVID-19 patients and spousal support, marital relationship, and birthrelated diseases. We found that COVID-19 positive and COVID-19 negative patients had similar BDI and BAI scores in the early (≤6 months) and late (6-18 months) postpartum periods. In addition, rates of anxiety and depression were similar in both groups at the same postpartum periods. Conclusion: In our study, COVID-19 infection in pregnancy had no significant additional impact on long-term postpartum maternal mental health.
ABSTRACT
Abstract Introduction: Different theories have been proposed on the etiology of tinnitus, including metabolic and audiologic causes. We suggest that mean platelet volume and neutrophil to lymphocyte ratio levels change in tinnitus, indicating microcirculatory disturbance and inflammatory process in the etiopathogenesis of tinnitus. Objectives: We aimed to evaluate the mean platelet volume and neutrophil to lymphocyte ratio in patients with tinnitus in comparison to healthy controls. Methods: Retrospective case-control study. Two-hundred and eighty-seven patients aged 18-59 years and diagnosed with tinnitus in the Ear, Nose, and Throat Clinic between December 2014 and May 2017 (patient group) and 275 healthy individuals who applied for a hearing screening within the same time period (control group). Demographics, concomitant diseases, laboratory results, and audiometric data were recorded. Mean platelet volume and neutrophil to lymphocyte ratio were the outcome measures. Patients with hearing loss due to presbycusis or another reasons, and patients with anatomical disorders in the external and middle ear were excluded from the study by using physical examinations, pure audio audiometry results and radiological imaging. The upper age limit was set at 59 to exclude presbycusis patients. Results: The ratio of female patients was higher in patient group than control group (58.5%, n = 168 vs. 49.4%, n= 127; respectively; p = 0.033). The mean age of patient group was significantly higher than those of control group (44.89 ± 10.96 years and 38.37 ± 10.65 years, respectively; p = 0.001). The percentage of subjects with high mean platelet volume level was significantly higher in patient group than control group (9.4%, n = 27, and 3.1%, n = 8 respectively; p = 0.008). The mean neutrophil to lymphocyte ratio was higher in patients with tinnitus than control group (1.95 ± 1.02 and 1.67 ±0.57, p = 0.012). A neutrophil to lymphocyte ratio level of 2.17 and above is associated with 1.991 times higher risk of tinnitus (odds ratio = 1.99, 95% confidence interval 1.31-3.02). Conclusion: High mean platelet volume and neutrophil to lymphocyte ratio values are associated with idiopathic tinnitus, suggesting the role of vascular pathologies in etiology of tinnitus. Tinnitus may be a sign of underlying systemic or local disorders. Therefore, patients with tinnitus should undergo detailed evaluation including hematological indices.
Resumo Introdução: Diferentes teorias já foram propostas sobre a etiologia do zumbido, inclusive causas metabólicas e audiológicas. Acreditamos que os níveis do volume plaquetário médio e da relação neutrófilos/linfócitos se alteram no zumbido, sugerem distúrbio microcirculatório e processo inflamatório na etiopatogenia do zumbido. Objetivo: Avaliar o volume plaquetário médio e a relação neutrófilos/linfócitos em pacientes com zumbido em comparação com controles saudáveis. Método: Estudo de caso-controle retrospectivo, com 287 pacientes entre 18 e 59 anos e diagnosticados com zumbido na Clínica de Otorrinolaringologia entre dezembro de 2014 e maio de 2017 (grupo pacientes) e 275 indivíduos saudáveis que solicitaram uma triagem auditiva no mesmo período (grupo controle). Foram registrados dados demográficos, doenças concomitantes, resultados laboratoriais e dados audiométricos. O volume plaquetário médio e a relação neutrófilos/linfócitos foram as medidas de desfecho. Pacientes com perda auditiva por presbiacusia ou por outros motivos e pacientes com distúrbios anatômicos na orelha externa e média foram excluídos do estudo por meio de exame físico, resultados de audiometria tonal pura e imagens radiológicas. O limite de idade superior foi fixado em 59 anos para excluir pacientes com presbiacusia. Resultados: A proporção de pacientes do sexo feminino foi maior no grupo de pacientes do que no grupo controle (58,5%, n = 168 vs. 49,4%, n = 127; respectivamente; p = 0,033). A média de idade do grupo de pacientes era significantemente maior do que a do grupo controle (44,89 ± 10,96 anos e 38,37 ± 10,65 anos, respectivamente; p = 0,001). A porcentagem de indivíduos com nível alto de volume plaquetário médio foi significantemente maior no grupo de pacientes do que no grupo controle (9,4%, n = 27 e 3,1%, n = 8, respectivamente; p = 0,008). A relação neutrófilos/linfócitos média foi maior nos pacientes com zumbido do que no grupo controle (1,95 ± 1,02 e 1,67 ±0,57, p = 0,012). Um nível de relação neutrófilos/linfócitos de 2,17 e acima está associado a um risco 1,991 vez maior de zumbido (odds ratio = 1,99, Intervalo de Confiança de 95% 1,31 a 3,02). Conclusão: Altos valores de volume plaquetário médio e relação neutrófilos/linfócitos estão associados ao zumbido idiopático, sugerem o papel de doenças vasculares na etiologia do zumbido. O zumbido pode ser um sinal de distúrbios sistêmicos ou locais subjacentes. Portanto, pacientes com zumbido devem ser submetidos a uma avaliação detalhada, inclusive índices hematológicos.

The first report about antimicrobial resistance was published in the 1940s. And today, the antimicrobial resistance has become a worldwide problem. Because of this problem, there is a need to develop new drugs. That's why we synthesized some novel thiazolidine-4-one derivatives and evaluated their antimicrobial activity. The final compounds were obtained by reacting 2-[(4,5-diphenylthiazol-2-yl)imino]thiazolidin-4-one with some aryl aldehydes. The synthesized compounds were investigated for their antimicrobial activity against four Candida species, five gram-negative and four gram-positive bacterial species. The lead compounds (4a- h) were obtained with a yield of at least 70%. All compounds showed antimicrobial activity. Compound 4f (MIC: 31.25 µg/ml) exhibited more efficacy than the other compounds against C. glabrata (ATCC 24433). Compound 4b (MIC: 62.5 µg/ml) was the most active compound against all bacterial species, particularly K. pneumoniae (NCTC 9633). Whereas, compound 4c (MIC: <31.25 µg/ml) was observed as the most active compound against E. coli (ATCC 25922). In general, all compounds (4a-4h) showed antimicrobial activity against all fungi and bacterial species. Compounds 4b (2,6-dichlorobenzylidene), 4c (2,6-dihydroxybenzylidene), 4f (1H-pyrrol-2- yl)methylene), 4g (4-triflouromethylbenzylidene) and 4h (2,3,4-trimethoxybenzylidene) were determined as the most active compounds

Abstract Introduction: We aimed to investigate whether vasoactive-inotropic score (VIS) is a predictor for early postoperative morbidity and mortality. Methods: This study was planned as a prospective cohort study, between Nov 20 2018 and May 15 2019, including a total of 290 patients aged 20 years or older who underwent elective on-pump coronary artery bypass grafting (CABG). Patients' demographic data, aortic cross-clamp and cardiopulmonary bypass times, European System for Cardiac Operative Risk Evaluation (EuroSCORE) score, cardiac ejection fraction (EF), VIS, intubation duration, and intensive care unit length of stay were recorded. Postoperative mortality and morbidity were recorded. Hourly doses of inotropes for VIS were recorded for each patient, and VIS was calculated. Results: Among the cases, 222 (77%) were male and 68 (23%) were female. The mean age of our patients was 62.5 years (37-86). Combined morbidity and mortality rates of our patients were 23.8%. An optimal cutoff point for VIS of 5.5 could predict combined morbidity and mortality with 90% sensitivity and 88% specificity. Low EF, prolonged operation time, high EuroSCORE, and high VIS are independent factors in the early postoperative period for the development of combined morbidity and mortality in patients who underwent elective CABG. Conclusion: VIS is the most critical and EuroSCORE is the second most important scoring systems. They independently predict combined morbidity and mortality in undergoing elective coronary artery bypass surgery.

PURPOSE: To report alterations in the anterior segment following accelerated corneal collagen cross-linking and topo-guided customized ablation treatment with the Nidek vision excimer laser system (Nidek Co., Ltd., Gamagori, Japan) in a single procedure. METHODS: We reviewed the medical records of patients who underwent cross-linking for progressive keratoconus. We divided patients into four groups based on the treatment protocol. Eyes were evaluated regarding uncorrected distance visual acuity, corrected distance visual acuity, keratometry (maximum [Kmax], equivalent keratometry readings, Ksteep and Kflat parameters), corneal elevations (anterior and posterior), the anterior radius of curvature, the posterior radius of curvature, anterior chamber volume, anterior chamber depth, anterior chamber angle and the pachymeter of the thinnest locale of the cornea before the surgery and at 1, 3, 6, and 12 months after the procedure. RESULTS: We included 259 eyes of 227 patients with progressive keratoconus who underwent treatment. The mean respective baseline uncorrected distance visual acuity and corrected distance visual acuity were: 0.68 ± 0.45 and 0.34 ± 0.40 in Group 1; 0.82 ± 0.44 and 0.33 ± 0.23 in Group 2; 0.61 ± 0.36 and 0.21 ± 0.17 in Group 3; and 0.65 ± 0.38 and 0.23 ± 0.18 in Group 4; logMAR did not show significant difference among the groups (p=0.14 and p=0.06, respectively). Visual improvements were better in the combined surgery groups. Mean Kmax in Groups 1, 2, 3, and 4 were 57.24 ± 7.51, 59.26 ± 6.94, 53.73 ± 4.60, and 54.31 ± 4.25 diopter (D), respectively. Group 1 demonstrated increased Kmax for 6 months. Maximum flattening by 3.38 ± 2.35 D 1 year after surgery was observed in Group 4 (p<0.05). Decreased anterior chamber angle, anterior chamber depth, and anterior chamber volume were similar, indicating the stability of the anterior chamber. CONCLUSION: Visual and anatomical improvement is better, with improved stability of the anterior segment, in combined surgery groups compared with cross-linking alone.

OBJECTIVE: To investigate whether a combination of the low-dose (1 µg) adrenocorticotropin (ACTH) stimulation test and glucagon stimulation test (GST) could overcome the problem of equivocal results with the GST or ACTH test alone in patients with pituitary disorders. METHODS: The study included 41 adult patients with pituitary disorders and 20 healthy subjects who underwent evaluation of cortisol response to ACTH, GST, and a combination of both tests. Blood samples for cortisol measurement were obtained at baseline and 30, 60, 90, and 120 minutes after intravenous administration of ACTH 1 µg and 90, 120, 150, 180, 210, and 240 minutes after subcutaneous injection of glucagon 1 mg. The combination test was performed by injecting ACTH 1 µg at the 180-minute time point of the GST, with blood samples for cortisol measurement obtained at 210 and 240 minutes. RESULTS: Overall, 28 patients with normal cortisol response to both tests also had a normal cortisol response to the combination test. Ten patients with adrenal insufficiency in both tests also had adrenal insufficiency in the combination test, including a patient who had a peak cortisol value of 12.4 µg/dL (which is the cutoff value for the combination test). Two patients with adrenal insufficiency in the ACTH stimulation test and one patient with adrenal insufficiency in the GST had normal cortisol responses to the combination test. CONCLUSION: By using an appropriate cutoff value, the combination test may offer additional information in patients with equivocal results in the GST and ACTH stimulation test.

Following the induction of oestrus out of season in small ruminants, low fertility and variations in fertility rates are associated with embryonic losses. One of the main causes of embryonic loss is luteal dysfunction. Gonadotropin Releasing Hormone (GnRH) supports the luteal structure, and increasing progesterone levels may be beneficial in terms of promoting embryonic life. The main objective of the present study was to evaluate the efficacy of GnRH administration following an oestrus induction protocol in the anoestrus season for preventing embryonic loss in goats having failure to conceive during the season. In the study, 106 Damascus goats aged 3-5 years and weighing 45-60 kg were used. The oestrus of 106 goats in the anoestrous group was stimulated with progesterone and pregnant mare serum gonadotropin (PMSG) treatment. Out of breeding season, goats were divided into the 4 following groups: GnRH0 (n = 27), GnRH7 (n = 26), GnRH0+7 (n = 27) and control (n = 26). In each goat, an intravaginal sponge (IS) containing 20 mg of fluorogestone acetate (FGA) was placed into the vagina and left for 9 days. With the withdrawal of the sponge, 550IU PMSG and 125 µg of d-cloprostenol were injected intramuscularly. Oestrus detection was made via teaser bucks for 3 days starting 24 h after withdrawal of the IS. Eighteen bucks known to be fertile were used for breeding. Goats in the oestrus period were mated via natural breeding. The GnRH analogue lecirelin was injected intramuscularly at breeding in the GnRH0 group, on day 7 post-breeding in the GnRH7 group, and both at breeding and on day 7 post-breeding in the GnRH0+7 group. No injections were given to the control group. Blood samples for progesterone measurement were taken by jugular vena puncturing on days 3, 6, 7, 10, 13, 16, and 19 after breeding from 10 randomly chosen goats in all groups. The goats with a level of > 3.5 ng/mL of progesterone on day 21 post-breeding were evaluated as pregnant. Pregnancy was also viewed on day 50 after breeding by real-time ultrasonography (USG) with a 5-7.5 MHz convex probe. The oestrus rate was 96.23% (102/106) in the goats. The rates of onset of oestrus between 36-48 h, 48-60 h and 60 h and beyond were 38.7% (41/106), 21.7% (23/106) and 35.8% (38/106), respectively. The total pregnancy rate was 35.8% (38/106). There were no statistically significant differences (P > 0.05) found for the pregnancy rate, embryonic death rate or progesterone concentration of the groups. However, serum progesterone levels were statistically different in the GnRH7 group compared with the control group (P < 0.05). After synchronisation, various anti-luteolytic strategies can be used to support corpus luteum development and elevate progesterone concentration in the luteal phase to decrease embryonic loss and increase reproductive performance. Therefore, application of GnRH to support the luteal structure and to increase progesterone levels may be beneficial in terms of supporting embryonic life. The results showed that GnRH treatment on the day 7 post-breeding following oestrus induction, including FGA and PMSG, can increase serum progesterone levels in Damascus goats in the anoestrus period. However, following oestrus induction in the anoestrus period, it was seen that GnRH treatment at breeding or on day 7 after breeding did not have any positive effect on embryonic loss or reproductive performance. In conclusion, it was considered that this protocol could be implemented successfully, yielding a 35% pregnancy rate in Damascus goats in the anoestrus period, but embryonic loss must be deeply studied in detail.(AU)

INTRODUCTION: Obesity is a growing public health problem associated with many comorbid diseases. The aim of this study was to evaluate the relationship between body mass index and complications of thyroidectomy. METHODS: Patients who underwent total thyroidectomy between January 2015 and December 2018 were enrolled. Patients were divided into two groups, i.e., BMI <25 (group A) and BMI≥ 25 (group B). Demographics, operative time, and complications were retrospectively reviewed. RESULTS: The study included 145 patients (66 in Group A and 79 in Group B). There was no significant difference between the two groups in terms of age (p=0.330) and gender (p=0.055). No surgical site infection and bleeding complications were observed in any patients. The mean operative time was 148.4 minutes (90-235) in Group A and 153.4 minutes (85-285) in Group B (p=0.399). Transient hypocalcemia was observed in 25 (37.9%) patients in group A, and 23 (29.1%) patients in Group B (p = 0.291). Permanent hypocalcemia was not observed in any patient in group A, and in 2 patients in Group B (2.5%) (p = 0.501). Transient recurrent nerve palsy was observed in 1 (1.5%) patient in Group A and in 3 (3.8%) patients in Group B (p=0.626). None of the patients had permanent recurrent nerve palsy. Parathyroid autotransplantation was performed on 1 patient (1.5%) in group A and on 7 (8.9%) patients in Group B (p=0.055). CONCLUSION: We think there is no relationship between a high BMI and thyroidectomy complications, and surgery can also be performed safely in this patient group.

ABSTRACT Introduction: It is well-known that pituitary dysfunction can develop as a result of traumatic brain injuries. One reason for such injuries is collision during contact sports. Objectives: The aim of this study was to investigate the effects of heading the ball and concussion on pituitary function in retired soccer players. Methods: Thirty-two retired soccer players, with an average age of 43.38 ± 5.49 (35-59) and 26 sedentary individuals with an average age of 43.31±6.38 (35-59) were included in this study. The subjects were questioned about their soccer-playing background, history of head trauma and concussion, and cardiometabolic diseases. One day one, blood samples were taken to investigate the baseline hematologic and biochemical parameters. On day two, the ACTH stimulation test was conducted, and on day three, glucagon stimulation tests were carried out. Resting EKG, transthoracic ECHO and exercise stress tests (for MET values) were also conducted. For the statistical analysis, The Student's t-test was used to compare the results of the two groups. The level of significance adopted was p<0.05. Results: It was identified that 5 out of 32 soccer players (16%) had experienced concussion during their soccer careers. The growth hormone (GH) levels of 3 retired soccer players (9.2%) and 3 sedentary individuals (10%) was below 1 ng/dl, which was accepted as the threshold value. There were no significant differences between hematological, biochemical and cardiometabolic parameters of the soccer players with low GH levels and those with normal GH levels. There was no significant relationship between the number of headers performed and GH deficiency. Conclusion: Although low GH levels were detected in almost 10% of the retired soccer players, the frequency of hypopituitarism was not higher than in the sedentary control group.

RESUMO Introdução: É fato conhecido que a disfunção hipofisária sobrevém em decorrência de lesões cerebrais traumáticas. Uma das razões para essas lesões é a colisão durante esportes de contato. Objetivo: O objetivo deste estudo foi investigar os efeitos do cabeceamento de bola sobre a hipófise e suas funções em jogadores de futebol aposentados. Métodos: Participaram deste estudo 32 jogadores de futebol aposentados com média de idade de 43,38 ± 5,49 (35-59) e 26 indivíduos sedentários com média de idade de 43,31 ± 6,38 (35-59) que foram questionados quanto à experiência como jogador de futebol, história de traumatismo craniano, concussões e doenças cardiometabólicas. No primeiro dia, foram obtidas amostras de sangue para investigar os parâmetros hematológicos e bioquímicos basais. No segundo dia, foi realizado o teste de estimulação com ACTH; no terceiro dia, foram feitos os testes de estimulação com glucagon. Além disso, foram realizados ECG de repouso, ecocardiograma transtorácico e testes de esforço para obter o equivalente metabólico (MET). Na análise estatística, o teste t de Student foi usado na comparação dos resultados dos dois grupos. O nível de significância foi estabelecido em p < 0,05. Resultados: Identificou-se que cinco dos 32 jogadores de futebol (16%) sofreram uma concussão durante a carreira futebolística. Os níveis de hormônio de crescimento (GH) de três jogadores de futebol (9,2%) e de três indivíduos sedentários (10%) foram inferiores a 1 ng/dl, valor que foi aceito como limiar. Não houve diferença significativa entre os parâmetros hematológicos, bioquímicos e cardiometabólicos dos jogadores de futebol com deficiência de GH e os jogadores de futebol com nível normal de GH. Não houve relação significativa entre o número de cabeceamentos e a deficiência de GH. Conclusão: Embora a deficiência de GH tenha sido detectada em quase 10% dos jogadores aposentados, a frequência de hipopituarismo não foi maior do que a dos controles sedentários. Nível de evidência I; Estudos Prognósticos.
RESUMEN Introducción: Es un hecho conocido que la disfunción hipofisaria sobreviene a consecuencia de lesiones cerebrales traumáticas. Una de las razones para esas lesiones es la colisión durante deportes de contacto. Objetivo: El objetivo de este estudio fue investigar los efectos de la cabezada en la pelota sobre la hipófisis y sus funciones en jugadores de fútbol retirados. Métodos: Participaron en este estudio 32 jugadores de fútbol retirados con promedio de edad de 43,38 ± 5,49 (35-59) y 26 individuos sedentarios con promedio de edad de 43,31 ± 6,38 (35-59) que fueron cuestionados cuanto a la experiencia como jugador de fútbol, historia de traumatismo craneano, concusiones y enfermedades cardiometabólicas. En el primer día, fueron obtenidas muestras de sangre para investigar los parámetros hematológicos y bioquímicos basales. En el segundo día, fue realizado el test de estimulación con ACTH. En el tercer día, fueron hechos los tests de estimulación con glucagón. Además, fueron realizados ECG de reposo, ecocardiograma transtorácico y tests de esfuerzo para obtener el equivalente metabólico (MET). En el análisis estadístico se usó el test t de Student en la comparación de los resultados de los dos grupos. El nivel de significancia fue establecido en p<0,05. Resultados: Se identificó que cinco de los 32 jugadores (16%) sufrieron una concusión durante la carrera futbolística. Los niveles de hormona de crecimiento (HC) de tres jugadores de fútbol (9,2%) y de tres individuos sedentarios (10%) fueron inferiores a 1 ng/dl, valor que fue aceptado como umbral. No hubo diferencia significativa entre los parámetros hematológicos, bioquímicos y cardiometabólicos de los jugadores de fútbol con deficiencia de HC y los jugadores de fútbol con niveles normal de HC. No hubo relación significativa entre el número de cabezadas y la deficiencia de HC. Conclusión: Aunque la deficiencia de HC haya sido detectada en casi 10% de los jugadores retirados, la frecuencia de hipopituitarismo no fue superior a la de los controles sedentarios. Nivel de evidencia I; Estudios pronósticos.
ABSTRACT
Los trastornos del ciclo de la urea (TCU) son enfermedades hereditarias con un posible desenlace desfavorable por hiperamoniemia grave. Se informa de una bebé con deficiencia de N-acetilglutamato sintasa (NAGS), quien tenía succión débil e hipotonicidad. Al examinarla, se observó hepatomegalia. El hemograma, los análisis y la gasometría eran normales, y las proteínas de la fase aguda, negativas. En los análisis, no se observaron cetonas en sangre, pero sí concentraciones elevadas de amoníaco. Las pruebas metabólicas no fueron concluyentes. Se inició el tratamiento de emergencia inmediatamente y recibió el alta el día 15 después del ingreso. Se confirmó deficiencia de NAGS mediante análisis de ADN. La paciente no tiene restricciones alimentarias ni toma medicamentos, excepto N-carbamil glutamato (NCG). La deficiencia de NAGS es el único TCU que puede tratarse específica y eficazmente con NCG. La detección temprana permite iniciar un tratamiento temprano y evitar los efectos devastadores de la hiperamoniemia
Urea cycle disorders (UCD), are genetically inherited diseases that may have a poor outcome due to to profound hyperammonemia. We report the case of a baby girl diagnosed as N-acetylglutamate synthase (NAGS) deficiency.The patient was evaluated due to diminished sucking and hypotonicity. Physical examination showed hepatomegaly. Complete blood count, biochemical values and blood gas analyses were normal, acute phase reactants were negative. Further laboratory analyses showed no ketones in blood and highly elevated ammonia. Metabolic tests were inconclusive. Emergency treatment was initiated immediately and she was discharged on the 15th day of admission. NAGS deficiency was confirmed by DNA-analysis. She is now without any dietary restriction or other medication, except N-carbamylglutamate (NCG).NAGS deficiency is the only UCD which can be specifically and effectively treated by NCG. Early recognition of disease will lead to early treatment that may prohibit devastating effects of hyperammonemia

RESUMO INTRODUÇÃO: A obesidade é um crescente problema de saúde pública associado a muitas doenças comórbidas. O objetivo deste estudo foi avaliar a relação entre o índice de massa corporal e as complicações da tireoidectomia. MÉTODOS: Os pacientes submetidos a tireoidectomia total entre janeiro de 2015 e dezembro de 2018 foram incluidos. Os pacientes foram divididos em dois como IMC <25 (grupo A) e IMC . 25 (grupo B). Demografia, tempo operatorio e complicacoes revisadas retrospectivamente. RESULTADOS: O estudo incluiu 145 pacientes (66 no grupo A e 79 no grupo B). Não houve diferença significativa entre os dois grupos em termos de idade (p = 0,033) e sexo (p = 0,055). Nenhuma infecção do sítio cirúrgico e complicações hemorrágicas foram observadas em nenhum paciente. O tempo operatório médio foi de 148,4 minutos (90-235) no grupo A e 153,4 minutos (85-285) no grupo B (p = 0,399). Hipocalcemia transitória foi observada em 25 (37,9%) pacientes do grupo A e 23 (29,1%) do grupo B (p = 0,291). Hipocalcemia permanente não foi observada em nenhum paciente do grupo A e em 2 pacientes do grupo B (2,5%) (p = 0,501). Paralisia nervosa recorrente transitória foi observada em 1 (1,5%) paciente no grupo A e em 3 (3,8%) pacientes no grupo B (p = 0,626). Nenhum dos pacientes apresentou paralisia nervosa recorrente permanente. O autotransplante de paratireóide foi realizado em 1 paciente (1,5%) no grupo A e em 7 (8,9%) pacientes no grupo B (p = 0,055). CONCLUSÃO:: Acreditamos que não há relação entre um IMC alto e as complicações da tireoidectomia e a cirurgia pode ser realizada com segurança também neste grupo de pacientes.
