RESUMO

BACKGROUND: The aim is to assess the value of strain elastography (SE) in differentiating likelihood of malignancy for the thyroid nodules, possessing the Bethesda Category III, IV, and V indeterminate cytology. METHODS: The data was obtained by ultrasonography (US)-guided fine-needle aspiration (US-g-FNA) via 27-gauge needle, with the verification of indicated thyroidectomies in a retrospective analysis, from April 2010 to April 2014, by enrolling the documents of 262 consecutive patients, with 327 thyroid nodules, subjected to one-surgeon performed neck US, SE, and US-g-FNA with 27-G needle to rule out the malignancy. RESULTS: 122 of 327 cases were Bethesda Category III, IV, and V with histopathologically benign, 110 (90.2%); PTC, 7 (5.7%); FTC, 4 (3.3%); HCC, 1 (0.8%). Tsukuba Elasticity Score (TES) 1, 2, 3, 4, and 5 were detected as 38 (31.1%), 8 (6.6%), 59 (48.4%), 4 (3.3%), and 13 (10.7%), respectively for the cases with the indeterminate cytology. No significant difference was detected between TES 4 and 5 and malign histopathology by McNemar test (p = .727) with a good level of concordance, the kappa coefficient, 0.737. CONCLUSION: SE may be a useful tool in differentiating malign from benign thyroid nodules by selecting surgery adaptation even for Bethesda indeterminate cytology on FNAC.

RESUMO

In this study, we aimed to investigate the effects of topical tramadol administration on corneal wound healing, and examine ophthalmic structures and intraocular pressure 7 days after tramadol administration. The experiments were conducted on eight male Wistar rats (250-300 g). After ophthalmic examination, epithelial cell layers in the central cornea were wounded. Rats received 30 µL of tramadol hydrochloride in one eye (Group Tramadol) and the same volume of vehicle in the other (Group Control) every 12 h for 7 days. Both eyes were stained with fluorescein dye, photographed, and wound area was calculated every 8 h until complete healing was observed. Eye blink frequency and corneal reflex tests were measured before and after drug administrations. After 7 days, slit lamp biomicroscopy, fundoscopy, Goldmann applanation tonometry, and histological evaluation were performed. There was no difference in the corneal wound healing rates between the tramadol and control groups. Reduction in wound area over time was also similar; group-time interaction was insignificant (F = 738.911; p = 0.225). Tramadol application resulted in blinking and blepharospasm for 30 s, but vehicle did not. Corneal reflex was intact and eye blink frequency test results were similar in all measurement times in both groups. Slit lamp biomicroscopy, fundoscopy, and intraocular pressures were within normal range. Corneal cells appeared unaffected by the repeated doses of tramadol for 7 days. Topical tramadol application on the cornea did not cause any side effect, except for initial temporary blinking and blepharospasm. Corneal wound healing was not affected, either.

RESUMO

OBJECTIVE: Diabetes mellitus, per se, is a global health concern, which is often accompanied by complications such as diabetic neuropathy. This prospective observational study purposed to assess the durations of spinal sensory block and motor blocks in individuals with and without diabetes mellitus who had undergone spinal anesthesia. METHODS: This study incorporated 80 cases, which were evenly divided into spinal sensory block without diabetes mellitus and spinal sensory block with diabetes mellitus. Various parameters were recorded at different time points, including heart rate, mean arterial blood pressure, SpO2, and spinal block characteristics. Notable measures included maximum spinal sensory block onset time, time to reach the 10th thoracic vertebra (T10), maximal spinal sensory block, time for Bromage scores, and block regression while controlling for age-related variations. RESULTS: Patients in the diabetic group exhibited extended block durations, with significant differences in heart rate noted at specific time points. Regarding the spinal block characteristics, the "maximum onset of SSB" and the "time to reach the T10" were more prolonged in the SSBwDM without significance. Maximum sensory spinal sensory block did not differ. However, some cases in the SSBwDM displayed blocks extending up to the T6. The times to achieve Bromage motor block scores 1-3 were shorter in SSBwDM and lost significance regarding age. Notably, the regression time was longer in SSBwDM, which held significance for both parameters. CONCLUSION: Diabetic cases commonly encounter prolonged block durations post-subarachnoid intervention, potentially linked to nerve sensitivity, age-related changes, and glycemic control. As such, attenuated local doses for diabetic neuropathic cases may enhance early mobilization, attenuate thromboembolic events, and expedite gastrointestinal recovery.

RESUMO

Protrusion of abdominal contents through the obturator foramen is a rare type of abdominal wall hernia. It is usually seen unilaterally and right-sided. Predisposing factors are old age, high intra-abdominal pressure, pelvic floor dysfunction, and multiparity. Obturator hernia has one of the highest mortality rates of all abdominal wall hernias, with a difficult diagnostic process that can be misleading even for the most experienced surgeons. Therefore, to suspect and easily diagnose an obturator hernia, it is important to understand its characteristics. Computerized tomography scanning remains the best diagnostic tool with the highest sensitivity. Conservative ap-proach is not recommended in obturator hernia cases. Once diagnosed, urgent surgical repair is indicated to prevent further ischemia, necrosis, and risk of perforation that can lead to peritonitis, septic shock, and death. Although open repair is a widely used and effective method for reducing abdominal hernias, including obturator, laparoscopic repairs have been described and become preferred. In this study, we present female patients aged 86, 95, and 90 years who were operated with the diagnosis of obturator hernia on computed tomography. The diagnosis of obturatory hernia should always be kept in mind, especially in the presence of acute mechanical intestinal obstruction findings in an elderly woman.

RESUMO

Aims and objectives Distal gastrectomy was a widely used therapeutic option for peptic ulcer and gastroesophageal reflux disease until quite recently. The consequences of anatomical and physiological changes following surgery in the gastric mucosa have been the object of interest for the scientist. In this study, we aimed to determine whether Helicobacter pylori (HP) infection and celiac disease were more common in patients with a history of distal gastrectomy. Materials and methods This is an observational retrospective study conducted at Giresun University Faculty of Medicine. The medical files of 35 patients with dyspepsia who had a history of distal gastrectomy for benign etiologies (antrectomy group) and 50 patients with dyspepsia (control group) were retrospectively analyzed. Results There were more males and older patients in the antrectomy group. Concerning the lab parameters, platelets, lymphocyte, and albumin levels were significantly lower, and urea, creatinine, anti-Endomisium Ig A (anti-EMA), and anti-tissue transglutaminase IgA (anti-tTGA) antibody positivity were significantly higher in the antrectomy group. Gastric biopsy results revealed a higher positivity of HP, atrophy, neutrophil, and lymphocytes in the antrectomy group. Correlation analysis revealed an inverse correlation between albumin and anti-EMA/atrophy positivity whereas a positive correlation between anti-EMA and HP/atrophy positivity. Conclusions HP infection and coeliac disease (CD) could be the problems that distal gastrectomy patients with dyspepsia can face during their follow-up. Concerning the pre-malignant potential of HP, its screening and eradication should be performed to prevent the malignant transformation of the remnant gastric tissue.

RESUMO

Long noncoding RNAs (lncRNAs) play an important role in regulating gene expression. Changes in their expression have been associated with many types of cancer, including thyroid cancer. This study aimed to investigate how changes in the expression of potassium voltage-gated channel subfamily Q member 1 opposite strand/antisense transcript 1 (KCNQ1OT1) and HAGLR opposite strand lncRNA (HAGLROS) lncRNAs correlate with the development and clinicopathological characteristics of papillary thyroid cancer (PTC). Reverse transcription-quantitative polymerase chain reaction was used to investigate the expression of lncRNAs in both tumor and adjacent normal thyroid tissue samples of the patients. Expressions of KCNQ1OT1 and HAGLROS were upregulated in the patients tumor samples compared to the adjacent normal thyroid samples. KCNQ1OT1 expression was linked to microcarcinoma and gender, while HAGLROS expression was linked to microcarcinoma and tumor size. When only microcarcinoma samples were evaluated, KCNQ1OT1 expression was higher in tumor tissues compared to normal tissues; however, no significant difference was observed in HAGLROS expression. Our data suggests that high expressions of KCNQ1OT1 and HAGLROS might contribute to the development of PTC and disease progression, and both lncRNAs may be potential therapeutic targets in PTC patients.

RESUMO

OBJECTIVE: Peptic ulcer perforation presents the most serious complication of ulcer disease with mortality that varies significantly depending on the age and conditions. The coronavirus disease 2019 pandemic was effective worldwide in 2020 and continues to date. The aim of this study was to investigate the initial clinical parameters and short-term outcomes of patients with acute peptic ulcer perforation before and during the coronavirus disease 2019 pandemic. METHODS: A retrospective cohort study was conducted in the Department of Surgery, University Hospital Ostrava, Czech Republic. The patients undergoing surgical modality of a simple suture of peptic ulcer perforation with/without omentoplasty in the post-coronavirus disease 2019 (January 1, 2020 to December 31, 2021) and the pre-coronavirus disease 2019 (January 1, 2018 to December 31, 2019) had been incorporated in this study. RESULTS: This study included a total of 46 cases (26 in the pre-coronavirus disease 2019, 20 in the post-coronavirus disease 2019). The age, body mass index, Boey score, duration of symptoms, surgery time, and length of hospital stay were comparable in both study subgroups. During the coronavirus disease 2019 pandemic, patients were admitted with a statistically significantly lower degree of perioperative risk according to the American Society of Anesthesiologists classification (p=0.013). Notably, 30-day postoperative morbidity was significantly higher in pre-coronavirus disease 2019 (73.1 vs. 55.0%, p=0.038). The mortality rate in the laparoscopic group was 13.6%, in the laparotomy group 41.4%, and the mortality rate was higher in pre-coronavirus disease 2019 than in post-coronavirus disease 2019 (34.6 vs. 20.0%, p=0.166). CONCLUSION: In fact, the coronavirus disease 2019 pandemic had not significantly influenced therapeutic management and short-term outcomes of patients undergoing acute surgical repair of peptic ulcer perforation.

RESUMO

OBJECTIVE: We aimed to detect the frequency of fibromyalgia syndrome in patients with rosacea and determine whether this frequency was affected by the severity of rosacea and the quality of life. METHODS: In this prospective, controlled, cross-sectional study, a total of 94 consecutive rosacea cases and 87 age- and sex-matched controls were enrolled. The severity of rosacea was assessed in light of the findings of the National Rosacea Society Ethics Committee. Dermatology Life Quality Index and Rosacea-specific Quality-of-Life instrument had been applied to the cases of rosacea. The diagnosis of fibromyalgia syndrome was established according to the 2016 revised fibromyalgia diagnostic criteria, and the Fibromyalgia Impact Questionnaire was used to determine the functional disability. RESULTS: The frequency of fibromyalgia syndrome was higher in the rosacea group than in the control group (p=0.01), and Dermatology Life Quality Index and Rosacea-specific Quality-of-Life instrument were higher in patients with rosacea with fibromyalgia syndrome (p=0.006 and p=0.004, respectively). A statistically significant weak positive correlation was observed between Dermatology Quality-of-Life Index, Rosacea-specific Quality-of-Life instrument, and Fibromyalgia Impact Questionnaire; symptom severity scale scores; and fibromyalgia score (r=0.35, r=0.259, and r=0.32 and r=0.376, r=0.305, and r=0.312, respectively). CONCLUSION: The patients with rosacea have higher rates and disability scores of fibromyalgia syndrome than healthy controls, independent of rosacea severity, and quality of life is correlated with fibromyalgia scores. We might point out that fibromyalgia syndrome accompanying rosacea has more restrictions in their daily routine activities than rosacea alone. As such, physicians should be aware of the possible coexistence of rosacea and fibromyalgia syndrome.

RESUMO

OBJECTIVE: In patients who experience difficulties in oral feeding, alimentary intake can be supported by creating direct access into the stomach through a percutaneous endoscopic gastrostomy. The present study purposed to compare naïve and exchanged percutaneous endoscopic gastrostomy tubes in terms of Helicobacter pylori infection and other clinical characteristics. METHODS: A total of 96 cases who underwent naïve or exchanged percutaneous endoscopic gastrostomy procedures with various indications were incorporated into the study. The patients' demographic data, such as age and gender, etiology of percutaneous endoscopic gastrostomy, anti-HBs status, Helicobacter pylori status, the presence of atrophy and intestinal metaplasia, biochemical parameters, and lipid profiles, had been analyzed. In addition, the anti-HCV and anti-HIV statuses had also been evaluated. RESULTS: The most common indication for percutaneous endoscopic gastrostomy placement was dementia in 26 (27.08%) cases (p=0.033). The presence of Helicobacter pylori positivity was significantly lower in the exchange group compared to the naïve group (p=0.022). Total protein, albumin, and lymphocyte levels were significantly higher in the exchange group compared to the naïve group (both p=0.001), and the mean calcium, hemoglobin, and hematocrit levels were statistically significantly higher in the exchange group (p<0.001). CONCLUSION: Preliminary outcomes of the present study revealed that enteral nutrition attenuates the incidence of Helicobacter pylori infection. Considering the acute-phase reactant, the significantly lower ferritin values in the exchange group suggest that there is no active inflammatory process in the patients and that immunity is sufficient.

RESUMO

OBJECTIVE: Hashimoto's thyroiditis, also known as chronic lymphocytic thyroiditis or autoimmune thyroiditis, is a considerable part of the spectrum of chronic autoimmune thyroid gland disorders which is pathologically associated with various degrees of lymphocytic infiltration. The purpose of the present study was to evaluate whether cartilage thickness is affected in patients with Hashimoto's thyroiditis or not in thyroidology. METHODS: A total of 61 individuals had been evaluated in this case-control study, including 32 euthyroid Hashimoto's thyroiditis patients and 29 healthy subjects comparable in age, sex, and body mass index. The patients with a history of knee trauma or knee surgery, an additional systemic disease such as diabetes mellitus, or an inflammatory disease like rheumatoid arthritis, systemic lupus erythematosus, and scleroderma had not been included in the study. The thickness of the femoral articular cartilage was measured using B-mode ultrasonography, and the right lateral condyle, right intercondylar area, right medial condyle, left medial condyle, left intercondylar area, and left lateral condyle were also measured. RESULTS: No statistically significant difference between patients with Hashimoto's thyroiditis diagnosis and healthy controls in terms of age, age groups, gender, and body mass index (p>0.05). CONCLUSION: As a consequence, no obvious connection between autoimmune markers and cartilage thickness in patients with Hashimoto's thyroiditis was recognized. Although the diverse manifestation of Hashimoto's thyroiditis could be observed, it seems to be no liaison between thyroid autoimmunity and cartilage thickness.

RESUMO

OBJECTIVE: The objective of this study was to compare the clinical outcomes of percutaneous dilatational tracheostomy in COVID-19 and non-COVID-19 patients. METHODS: A total of 48 patients who underwent percutaneous dilatational tracheostomy, with 24 COVID-19 patients (Group C) and 24 non-COVID-19 patients (Group N), were included in the study. Patients' demographic features including age and gender, time to intubation, duration of intubation, Acute Physiology and Chronic Health Evaluation scores, comorbidities, duration of opening tracheostomy, complications, duration of mechanical ventilation, length of stay in the intensive care units, and mortality were recorded and compared between the groups. RESULTS: There was no statistically significant difference between the groups regarding age and gender (p=0.558 and p=0.110, respectively). Time to intubation was significantly more prolonged, and intubation follow-up duration was significantly shorter in Group C compared to Group N (p=0.034 and p=0.002, respectively). The Acute Physiology and Chronic Health Evaluation score was statistically significantly higher in Group N compared with Group C (p=0.012). The most common comorbidity was hypertension in 29 (60.4%) patients, followed by cerebrovascular disease in 19 (39.6%) patients. There was no statistically significant difference between the groups regarding mortality (p=0.212). CONCLUSION: This study suggests that percutaneous dilatational tracheostomy can be performed safely in COVID-19 and non-COVID-19 patients. However, COVID-19 patients may have a longer time to intubation and shorter intubation follow-up duration than non-COVID-19 patients. The study also found a higher incidence of complications in COVID-19 patients undergoing percutaneous dilatational tracheostomy. These results emphasize the importance of careful patient selection, meticulous technique, and close postoperative monitoring in patients undergoing percutaneous dilatational tracheostomy, particularly in those with COVID-19.

RESUMO

OBJECTIVE: Our study purposed to examine the complex relationship between low-molecular-weight heparin therapy, multiple pregnancy determinants, and adverse pregnancy outcomes during the third trimester in women with inherited thrombophilia. METHODS: Patients were selected from a prospective cohort of 358 pregnant patients recruited between 2016 and 2018 at the Clinic for Obstetrics and Gynecology, University Clinical Centre of Serbia, Belgrade. RESULTS: Gestational age at delivery (ß=-0.081, p=0.014), resistance index of the umbilical artery (ß=0.601, p=0.039), and D-dimer (ß=0.245, p<0.001) between 36th and 38th weeks of gestation presented the direct predictors for adverse pregnancy outcomes. The model fit was examined using the root mean square error of approximation 0.00 (95%CI 0.00-0.18), the goodness-of-fit index was 0.998, and the adjusted goodness-of-fit index was 0.966. CONCLUSION: There is a need for the introduction of more precise protocols for the assessment of hereditary thrombophilias and the need for the introduction of low-molecular-weight heparin.

RESUMO

OBJECTIVE: This study aimed to evaluate our experience with the use of Magseed, the magnetic metallic marker, as a localization technique followed by Sentimag probe detection in patients with solitary intra-abdominal local metastases with subsequent resection of the lesions. METHODS: Five patients underwent resection after the lesion was marked with the Magseed magnetic marker. Prior to the surgery, a computed tomography scan of the chest and abdomen and/or positron emission tomography was performed to rule out the dissemination of the disease. The indication for surgery was evaluated in a meeting of a multidisciplinary team, and the placement of the magnetic marker under computed tomography control had been performed the day before the planned procedure. RESULTS: The present preliminary outcomes have revealed that Magseed might be a promising technique that is feasible and safe, particularly when the postsurgical anatomic conditions in the abdominal cavity are altered and the lesions are not visible or palpable. Surgical extirpation of lesions occurred without complications in each case. In all the cases, the resection was complete and curative, and one wound infection in all (20%), without any major complications, had occurred. The mean hospital stay was 6.6 days. CONCLUSION: Magseed utilization, as a localization technique, followed by Sentimag probe detection in intra-abdominal tumors has not been reported before. Improving the visualization and, consequently, the precise marking of the lesion with subsequent radical removal can prevent insufficient or excessive removal of healthy tissue, leading to a faster diagnosis and better overall clinical outcomes.

RESUMO

OBJECTIVE: This study purposed to evaluate preoperative two tumor markers, namely, carcinoembryonic antigen and carbohydrate antigen (CA)19-9, in colorectal cancer for anatomotopographic location with disease stage and to assess their utility for diagnostic staging purposes. METHODS: The study retrospectively incorporated patients who had undergone surgery for colorectal cancer at our department in 2015-2018 and in whom carcinoembryonic antigen and CA19-9 tumor markers had been preoperatively analyzed. The obtained data were then statistically processed using R-project. RESULTS: A total of 155 patients had been incorporated, of whom 96 (62%) were men and 59 (38%) were women. Rectum was the most common location (74 patients, 48%), and the least represented stage was IV (18, 12%). The marker carcinoembryonic antigen was obtained in all 155 cases, while CA19-9 was in 105. The median carcinoembryonic antigen was 3 (0.34-1104.25), and the median CA19-9 was 12 (0.18-840.00). A significance was recognized between median carcinoembryonic antigen and disease stage (p-value=0.016), with stages I, II, and III (medians 2, 3, and 2) different from stage IV (median 13), while no significance for CA19-9 was recognized (p-value=0.343). No significance between either marker and location (carcinoembryonic antigen: p=0.276; CA19-9: p=0.505) was detected. The testing was performed at a significance level of alpha=0.05. CONCLUSION: This study revealed a significance between the marker carcinoembryonic antigen, but not CA19-9, and the disease stage, while no relationship of either of these markers with tumor location was found. Herewith, the study confirmed that higher carcinoembryonic antigen values may suggest the finding of more advanced forms of colorectal cancer and thus a worse prognosis of this malignant phenomenon.

RESUMO

OBJECTIVE: This study aimed to determine the computed tomography findings associated with very recent catastrophic 2023 Turkey-Syria earthquake-related injuries and their anatomotopographic distribution in the adult population. METHODS: The incorporated computed tomography scans of 768 adult cases who had been admitted to the hospital and had undergone computed tomography imaging after these tragic disasters had been examined on the Teleradiology Reporting System of the Turkish Ministry of Health. To this end, the injuries were classified into six categories: head, thoracic, spinal, pelvic, extremity, and abdominal injury, with three age groups (18-34, 35-64, and ³65 years) and four different imaging intervals (<24, 24-48, 49-72, and >72 h). RESULTS: This study incorporated 316 (41.1%) cases on the first day, 57 (7.5%) on the second day, 219 (28.5%) on the third day, and 176 (22.9%) on the fourth day after the earthquake or later. Of the 768 cases, 109 (14.2%) had a head injury, 100 (13.0%) had a thoracic injury, 99 (12.9%) had a spinal injury, 51 (6.6%) had a pelvic injury, 41 (5.4%) had an extremity injury, and 11 (1.4%) had an abdominal injury. CONCLUSION: In these regrettable earthquake disasters, we determined a high ratio of head injuries, which was closely followed by thoracic and spinal injuries, in our preliminary outcomes for the pediatric population, Part I. The frequency of abdominal injuries was low among individuals who experienced the earthquake. Last but not least, we have noticed a higher likelihood of spinal injury in individuals older than 65 years in the studied population.

RESUMO

OBJECTIVE: This study was carried out to evaluate the injuries in pediatric earthquake victims due to the 2023 Turkey-Syria earthquakes with computed tomography and determine the anatomotopographic distribution of injuries. METHODS: The material of this retrospective study consisted of the computed tomography findings of 257 pediatric cases injured in the 2023 Turkey-Syria earthquakes, and those were divided into subgroups based on their age group, i.e., 0-4, 5-9, 10-14, and 15-18 years, and the type of injury, i.e., head, maxillofacial, thoracic, abdominal, pelvic, and spinal injuries. RESULTS: Earthquake-related injuries had been detected in 102 (39.6%) patients. Of the 29 patients with multiple injuries, 17, 10, and 2 had injuries in two, three, and four topographic regions, respectively. The most common injury was a head injury, which was detected in 48 (18.7%) cases, followed by thoracic injury, spinal injury, pelvic fracture, abdominal injury, and maxillofacial fracture, which were detected in 40 (15.6%), 22 (8.5%), 19 (7.4%), 10 (3.9%), and 6 (2.3%) patients, respectively. The cranial bone fractures and intracranial injuries were significantly more frequent in the 0-4 years age group compared with other age groups (p=0.028 and p=0.024, respectively). The rib fractures with spinal and pleural injuries were significantly more common in the 15-18 years age group compared with others (p=0.016, p=0.004, and p=0.002, respectively). CONCLUSION: The head injury was the most common earthquake-related injury in pediatric cases. Herein, it was more common in younger children compared with other age groups, whereas rib, spine, and pleural injuries were more common in older children.

RESUMO

Programmed Cell Death-1 (PCD-1) is a key immune checkpoint receptor, which mainly expresses on activated T, B, Dendritic (DC), Natural Killer (NK), and Treg cells. On the surface of activated T-cells, PCD-1 expression is upregulated after the recognition of peripherals antigens by T cells; subsequently, the elevated binding of PD-1 to Programmed Death Ligand-1 (PD-L1) and Programmed Death Ligand-2 (PD-L2) becomes a key step for downstream inhibitory signaling. Although the role of PD-L1 has been evaluated more thoroughly by clinical research, and PD-L1 has also been used more widely in the clinical setting, PD-L2 also plays an important role in the negative regulation of T-cells, one of the necessary conditions that lead to immune tolerance. Expression of PD-L1 either in tumors or in infiltrating immune cells has been verified predominantly by Immunohistochemistry (IHC) in a variety of tumors, suggesting a role for the PD-1/PD-L1 axis as a prognostic trait and therapeutic target across multiple histotypes. The complex interplay between these factors plays a major role in the diffusion and clinical application of PD-L1 IHC assays as predictive biomarkers of response to PD-1/PD-L1 inhibitors. Checkpoint blockades are registered for the treatment of various cancers, including gynecological malignancies.

RESUMO

OBJECTIVE: There is an increase in the prevalence of pre-gestational diabetes in the past decades, mainly due to the increase in the prevalence of obesity in the general population and consequently type 2 diabetes among women of reproductive age. METHODS: This study purposed to describe the delivery characteristics, pregnancy complications, and outcomes among women in Serbia with the pre-gestational type 2 diabetes in the past decade, as well as their pregnancy complications, deliveries, and neonatal outcomes. The study included data from all the pregnant women with pre-gestational type 2 diabetes in Belgrade, Serbia during the period between 2010 and 2020. The final sample consisted of 138 patients. RESULTS: More than half, i.e., 70 (50.7%) had a vaginal delivery, while 48 (34.8%) had elective and 20 (14.5%) had emergency caesarean sections. Throughout the period, there was 1 patient with preeclampsia (0.7%), 5 with pregnancy-induced hypertension (3.6%), 7 had newborns with small for gestational age (5.1%), 28 with macrosomia (20.3%), 12 (8.7%) had preterm births, and one-fifth, i.e., 28 (20.3%) of the newborns had Apgar score under 8. CONCLUSION: The present study revealed that women with type 2 diabetes in pregnancy have a significant burden of pregnancy complications, related to pregnancy, delivery, and newborns.

RESUMO

OBJECTIVES: Ad fontes, the status of the thyroid gland, and metabolic disturbance lead to the alteration of oxygenation. In pregnancy, it is particularly crucial to possess all predictive parameters. METHODS: This cross-sectional study was conducted at the Clinic of Gynecology and Obstetrics, Clinical Center of Serbia, Belgrade, Serbia, between 2017 and 2021 which study included a total of 99 women who had been admitted for preterm delivery and had undergone thyroid analysis, detected Hashimoto thyroiditis, and Oral Glucose Tolerance Test (OGTT) 40 days after delivery and had pathological Homeostatic Model Assessment for Insulin Response (HOMA IR) indices. In the group of urgent patients with preterm delivery, we looked after not only routine Doppler of the umbilical artery, but we measured specific ratios such as the Cerebroplacental ratio (CP). RESULTS: The mean maternal age was 32.23 ± 5.96 years and the mean gestational age was detected as 35.40 ± 2.39 weeks. The delivery was completed vaginally in 77 women (78%) and surgically in 22 (22%). The Mean APGAR score was 8.44 ± 1.18, the mean birth weight was 2666.87 ± 622.17g and the cases undergoing cesarean section had significantly higher values of pulsatility index (1.85 ± 0.27 vs. 1.34 ± 0.31) and CP (1.22 ± 0.26 vs. 0.47 ± 0.17). CONCLUSIONS: The introduction of Doppler sonography for blood flow assessment helps to form a complete clinical description of the patient, particularly in conditions where oxidative stress became provocative by the thyroid gland antibodies and gestational diabetes in Thyroidology.

RESUMO

OBJECTIVE: The present study purposed to determine characteristics of ovarian carcinoma and to analyze predictors of survival in patients with ovarian carcinoma. METHOD: A retrospective cohort study was conducted including the patients with diagnosed ovarian carcinoma treated at the Clinic for Operative Oncology, Oncology Institute of Vojvodina in the period from January 2012 to December 2016. Seventy-two women with ovarian carcinoma were included in the analysis. The data about the histological type of tumor, disease stage, treatment, lymphatic infiltration, and surgical procedure were collected retrospectively, using the database of the institution where the research was conducted (BirPis 21 SRC Infonet DOO ‒ Information System Oncology Institute of Vojvodina). Descriptive statistics and multivariate analysis using Cox proportional hazards model were performed. RESULTS: The univariate Cox regression analysis identified histology, tumor grade, FIGO (International Federation of Gynecology and Obstetrics) stage, NACT (Neoadjuvant Chemotherapy), number of therapy cycles, type of surgery, and chemotherapy response as independent predictors of mortality. Finally, the type of tumor and chemotherapy response had an increased hazard ratio for mortality in the multivariate Cox regression model. Herewith, the percentage of high-grade, advanced-stage ovarian cancer patients with complete response to chemotherapy, absence of recurrent disease, and lymphovascular space invasion were significant predictors of survival in patients with ovarian carcinoma. CONCLUSIONS: Herein, emerging data regarding precision medicine and molecular-based personalized treatments are promising and will likely modify the way the authors provide multiple lines of treatments in the near future.
