RESUMO

Dyslipidemia is a component of metabolic syndrome, having an important role in the carcinogenesis of different tumor types, such as prostate, ovarian, or renal cancer. The number of studies on the predictive potential of the different components of the lipid profile with a predictive potential in breast cancer is quite low. The evaluation of the lipid profile was carried out for the 142 patients who benefited from neoadjuvant therapy (NAC) in order to identify a potential predictive biomarker. The serological sample collection was performed sequentially according to a standardized protocol, pre-NAC, post-NAC and 6 months post-NAC after a 6-h pre-collection fast. We also investigated in the general group the presence or absence of the p53 mutation (TP53) and of the mitotic index ki-67, respectively, in relation to the molecular subtypes. The menopausal status, tumor size, family history, grading, Ki-67, p53 and LN metastases have a predictive nature regarding overall survival (OS) (p < 0.05), while for disease free survival (DFS), only tumor size, tumor grading, Ki-67 > 14, and p53+ are of predictive nature. The genetic and molecular analysis carried out in our group indicates that 71.67% have a Ki-67 score higher than 14%, and 39% of the patients have the positive P53 mutation. The multivariate analysis in the case of patients included in the TNBC subtype showed that the increased tumor volume (p = 0.002) and increased level of HDL (p = 0.004) represent predictive factors for the tumor response rate to NAC. High HDL-C levels before NAC and increased LDL-C levels after NAC were associated with the better treatment response in ER-positive and HER2+ breast cancer patients. Increased HDL-C values and tumor volume represent predictive factors as to the response rate to NAC in the case of patients included in the TNBC subtype. Regarding the ER+ and HER2+ subtypes, increased levels of HDL-C pre-NAC and increased levels of LDL-C post-NAC were associated with a better therapeutic response rate. Tumor grading, Ki-67, p53, and LN metastases have a predictive nature for OS, while tumor size, tumor grading, and Ki-67 > 14, and p53+ are predictive for DFS.

RESUMO

Introduction: Endometrial cancer is the most common form of gynecological cancer in developed countries. Current recommended therapeutic management takes into account a number of factors such as: TNM stage, justification for primary surgery, desire to preserve fertility. For primary operable cases, surgical staging has become an extremely important pillar, in which the status of the pelvic lymph nodes needs to be known (1-3). Material and Method: Between August 2015 and June 2021, a multicenter prospective observational study was performed in the "Prof. Dr. I. Chiricuta" Oncological Institute Cluj Napoca, 2nd Department of Surgery of "Pius Brinzeu" County Hospital Timisoara, 1st Department of General Surgery of Arad County Hospital, 2nd Department of Obstetrics and Gynecology "Dominic Stanca" Cluj Napoca and "Dr. Carol Davila" Central Military Emergency University Hospital Bucharest, Romania with the main aim of examining the sentinel lymph node detection rate using methylene blue as a tracer. Surgeries were performed by the team of surgeons of the mentioned clinics, and patients were informed about this study and signed an informed consent form for enrollment. Results: A total of 116 cases met the inclusion criteria for this prospective study. The mean age of the included patients was 62.3 years (minimum - 38, maximum - 83). The mean body mass index was 31.8 (minimum - 19.9, maximum - 48.2). In terms of histological type of the endometrial cancer, the majority of cases were endometrioid cancer, amounting to 72.5% of the total (n=84). A considerable number of cases were of mixed type, either with clear cell carcinoma (8.6%, n=10) or mixed carcinosarcoma (17.2%, n=20). The preferred approach for surgery was laparoscopic surgery rather than traditional surgery (72% vs 28%). Another element investigated from a histological point of view is the tumour grading, the degree of differentiation of cells with anarchic development, we note that 50% (n=58) were G2. Of the 116 cases of endometrial carcinoma included in the study, in 83% of cases (n=96) methylene blue tracer injection was successful and sentinel node was identified. The SLN technique continues to be of great interest and use in surgical centers around the world. The method of detecting sentinel lymph nodes varies depending on the individual. According to literature studies, indocyanine (ICG- Indocyanine green) is the gold standard for lymph node mapping, with superior detection rates when compared to other existing versions. Another key factor to consider when selecting a sentinel node identification method is cost-effectiveness. The use of methyl blue as a marker tracer is the most cost-effective option with equivalent detection rate outcomes. Conclusions: Based on the results of our study and other studies in the literature, lymphatic mapping using methylene blue as a tracer in endometrial cancer is a cost-effective method with a favourable detection rate. With this low-cost procedure we can achieve a correct tumor staging, avoiding overtreatment. There are multiple ways to identify the sentinel node using different tracers with higher accuracy, but the objective of the study was not to make a comparison between different tracers, but to present the feasibility of lymph node mapping using methylene blue as a low cost tracer with good reproducibility, short learning curve and optimal detection rate.

RESUMO

Oral contraceptives (OCs) are widely used due to their efficiency in preventing unplanned pregnancies and treating several human illnesses. Despite their medical value, the toxicity of OCs remains a public concern. Previous studies indicate the carcinogenic potential of synthetic sex hormones and their link to the development and progression of hormone-dependent malignancies such as breast cancer. However, little is known about their influence on the evolution of triple-negative breast carcinoma (TNBC), a malignancy defined by the absence of estrogen, progesterone, and HER2 receptors. This study reveals that the active ingredients of modern OCs, 17ß-Ethinylestradiol, Levonorgestrel, and their combination induce differential effects in MDA-MB-231 TNBC cells. The most relevant behavioral changes occurred after the 24 h treatment with 17ß-Ethinylestradiol, summarized as follows: (i) decreased cell viability (64.32% at 10 µM); (ii) cell roundness and loss of confluence; (iii) apoptotic aspect of cell nuclei (fragmentation, membrane blebbing); and (iv) inhibited cell migration, suggesting a potential anticancer effect. Conversely, Levonorgestrel was generally associated with a proliferative activity. The association of the two OCs exerted similar effects as 17ß-Ethinylestradiol but was less effective. Further studies are necessary to elucidate the hormones' cytotoxic mechanism of action on TNBC cells.

RESUMO

Introduction: Sclerosing Extramedullary Hematopoietic Tumor (SEHT) is a very rare lesion associated with chronic myeloproliferative disorders (CMPD). SEHT can mimic morphologically, both macroscopically and microscopically, a wide variety of tumors/lesions. Case presentation: We present the case of a female patient diagnosed with gallstones for which surgery was decided. Intraoperatively, a malignant tumor of extrahepatic bile ducts was suspected. A frozen section examination raised the suspicion of a mesenchymal tumor or an inflammatory pseudotumor. The histological evaluation of the permanent sections, supplemented with an immunohistochemical investigation (IHC), was the one that established the diagnosis of SEHT, based on the presence of areas of sclerosis, atypical CD31+ megakaryocytes, myeloid and erythroid elements. Conclusions: The authors present the difficulties of a morphological diagnosis on the frozen section and on permanent sections in the absence of relevant clinical information and make a review of the literature data dedicated to the subject.

RESUMO

Background: Thyroid surgery has various benign and malignant indications. A complete pre-surgical evaluation guides the selection of cases and determines the appropriate extent of the intervention. Minimizing the number of unneeded thyroidectomies could reduce hospitalization costs, as well as post-surgery complications and iatrogenic hypothyroidism. The aim of this study was to retrospectively evaluate the presenting reasons of patients admitted to the hospital for thyroid surgeries and to estimate the need of total thyroidectomies. Methodology: The study included patients admitted in all three Surgical Departments in Timisoara Emergency County Hospital, between January 1st 2018 and December 31st 2019 (2 years). Results: A number of 1036 thyroid surgeries had been performed in 1027 patients and were retrospectively analyzed, comparing the pre-surgical diagnosis with the pathology report. Suspicion of malignancy, compression or functional autonomy was described in 326 /824 total thyroidectomy cases. Cancer was detected in 338 out of the 1027 patients (32.92%), including 39 borderline lesions. A proportion of 80.7% were papillary thyroid cancers. The current presurgical evaluation generated a number of 475 cases displaying differences between the presurgical and postsurgical diagnostic. The phenomenon was observed both in total thyroidectomy and in lobectomy interventions: 22.8% of the lobectomies were diagnosed with thyroid cancer. Conclusion: Our findings confirm that a reliable multidisciplinary approach with standardized presurgical clinical, biochemical and ultrasound evaluation is crucial in patients with indication for thyroid surgery, in order to avoid unnecessary surgeries.

RESUMO

BACKGROUND: The aims of our study were to compare serum acylated ghrelin (the active form of ghrelin) concentrations before and after the surgery of patients undergoing laparoscopic sleeve gastrectomy (LSG) or laparoscopic greater curvature plication (LGCP) and to correlate these levels with excess weight loss and hunger sensations on a short-term basis. METHODS: The patients included in the study had either (1) a body mass index (BMI) over 35 kg/m2 and one comorbidity or (2) a BMI over 40 kg/m2. Ghrelin levels were measured on the day of the surgery, 1 month after the procedure, and 3 months after the procedure. A questionnaire about hunger sensation was administered to the patients, and changes in the patients' weights were evaluated on the same timeline as the measurement of the ghrelin levels. RESULTS: Eighteen obese patients were included in the study, including 10 patients in the LSG group and 8 patients in the LGCP group. All the procedures were performed laparoscopically. The average level of preoperative ghrelin in the LSG group was 212.21 pg/mL ± 140.57 SD. After 1 month, the average ghrelin level in the LSG group was 74.47 pg/mL ± 29.55 SD (p = 0.01), and it was 41.47 pg/mL ± 15.19 SD (p = 0.002) after 3 months. The average level of preoperative ghrelin in the LGCP group was 318.08 pg/mL ± 161.70 SD. It decreased to 190.58 pg/mL ± 116.75 SD (p = 0.01) after 1 month and to 91.57 pg/mL ± 56.70 SD (p = 0.004) after 3 months. Comparing the two groups, hunger sensation had decreased more in the LSG group (p = 0.03) 3 months after the surgery. CONCLUSIONS: Laparoscopic sleeve gastrectomy (LSG) and laparoscopic greater curvature plication (LGCP) produced the same weight loss and diminished hunger sensation in the short term on the selected patients. LSG had an increased effect on ghrelin levels when compared with LGCP at 1 month after the procedure and 3 months after the procedure.

RESUMO

Introduction: Obesity is one of the leading causes of social, economic and health problems throughout the world and in the past years bariatric surgery has emerged as a method to alleviate this problem. We have conducted an experimental study aimed at comparing the metabolic and hormonal changes after sleeve gastrectomy and mini gastric by-pass, two bariatric procedures showing promising results. Material and Methods: We have designed a study using a rat model with induced type 2 diabetes mellitus and obesity divided into three groups: a sleeve gastrectomy group, a mini gastric by-pass group and a sham operated group, all of which had their glycemia, lipid profile, ghrelin and insulin levels measured before and after the procedures. Results: The results showed a significant decrease (p 0.05) in fasting glucose levels, lipid profile and ghrelin levels in the mini gastric bypass compared to the sleeve gastrectomy group. Conclusions: This study has demonstrated that both SG and MGB are effective treatments for morbid obesity and T2DM and both procedures can significantly resolve obesity-related metabolic changes.

RESUMO

AIM: The purpose of the study was to compare the results of laparoscopic inguinal hernia repair using two different methods: transabdominal preperitoneal (TAPP) repair and the technique of totally extraperitoneal repair (TEP). METHODS: In this retrospective study were included 90 cases of inguinal hernia that underwent for laparoscopic approach of inguinal hernia repair at the Emergency County Hospital Timisoara at the 2nd Surgical Clinic between 2012 and 2013. The primary outcome was recurrence of the hernia at two years follow-up. Secondary outcomes were short and long-term complications: hematoma and seroma formation, inflammation of the testis, chronic inguinal pain, reoperation, 30 days mortality. RESULTS: Of the 90 patients who underwent unilateral hernia repair, 70 were completely followed-up for 24 months, 36 (81.81%) patients with TEP and 34 (73.91%) with TAPP. Regarding the main outcome there was no recurrence of the hernia at two years follow-up.There were two cases of bleeding in the TAPP group;both were managed by laparoscopic sealing of the damaged vessels, 8 cases of post-operative edema of testis in TAPP and 3 cases in TEP. Regarding thesubcutaneous emphysema there were 16 cases in TAPP and 3 cases in TEP. CONCLUSIONS: Differences between TEP and TAPP in our study were related to minor complications, no major complications occurred. After the two years follow-up of 70 of a total of 90 patients, there was no recurrence of the hernia.

RESUMO

Small bowel tumors are relatively rare, representing only around 5% of all gastrointestinal neoplasms, with a progressively increasing incidence. Currently, there are no established guidelines for diagnostic approaches, screening procedures, or management strategies for small bowel tumors. We present here the case of a patient with a rare type of metastatic tumor of the small bowel originating from primary lung adenocarcinoma who presented with abdominal pain, severe iron-deficiency anemia, and melena. The initial investigations, gastroscopy and colonoscopy, failed to identify the bleeding source. The obscure bleeding source and diagnosis were achieved through power motorized spiral enteroscopy (MSE), which allowed the visualization and biopsy of the tumor. Histopathological examination established the presence of a poorly differentiated non-mucinous adenocarcinoma originating from the lung. This case is reported to provide evidence of the efficiency of MSE in the diagnosis of small bowel tumors, with the method providing higher insertion depth in a reduced amount of time.

RESUMO

Pancreaticolithiasis represents a rare phenomenon, being superimposed most of the time on a form of chronic pancreatitis of multifactorial etiology. Pancreaticolithiasis is a late complication of the phenomenon of chronic pancreatitis. The reverberant inflammatory process, followed by the fibrotic degeneration of the pancreatic parenchyma, and pancreatic fluid stasis at the ductal level are factors that contribute to the phenomenon of calcium precipitation. This article describes the case of a patient with a diagnosis of pancreaticolithiasis (Wirsung duct lithiasis), a phenomenon superimposed on chronic pancreatitis of ethanolic cause (Rosemont classification). It was decided to perform surgery via the classical approach with the perfection of corporeo-caudal pancreatectomy and preservation of the splenic vessels (Kimura procedure) with pancreatico-jejunal anastomosis on the Roux-en-Y loop. The aim of this study is to identify the best method of treatment for pancreaticolithiasis. To enhance the case and provide a basis for standardization, a literature review was carried out, which included a total of six articles. The results of this study highlight that, currently, the management of symptomatic pancreaticolithiasis encompasses medical therapy (enzyme replacement therapy), interventional therapy (ESWL (extracorporeal shock wave lithotripsy) ± ERCP (endoscopic retrograde cholangiopancreatography), ERCP + sphincterotomy + stent insertion, and POP (oral pancreatoscopy)), and surgical treatment. In conclusion, based on the analysis conducted in this study, the size of the calculi present determines which is the suitable therapeutic care. Unlike stones over 0.5 cm, when surgery is explicitly advised for therapeutic purposes in the absence of endoscopic techniques, stones under 0.5 cm should be treated using endoscopic procedures.

RESUMO

(1) Background: The present study aims to evaluate the reduction of postoperative pain in breast surgery using a series of local analgesics, which were infiltrated into the wound; (2) Methods: Envelopes containing allocation were prepared prior to the study. The patients involved were randomly assigned to the groups of local anesthesia infiltration (Group A) or normal pain management with intravenous analgesics (Group B). The random allocation sequence was generated using computer-generated random numbers. The normally distributed continuous data were expressed as the means (SD) and were assessed using the analysis of variance (ANOVA), independent-sample t-test, or paired t-test; (3) Results: The development of the postoperative pain stages was recorded using the VAS score. Therefore, for Group A, the following results were obtained: the VAS at 6 h postoperatively showed an average value of 0.63 and a maximum value of 3. The results for Group B were the following: the VAS score at 6 h postoperatively showed an average value of 4.92, a maximum of 8, and a minimum of 2; (4) Conclusions: We can confirm that there are favorable statistical indicators regarding the postoperative pain management process during the first 24-38 h after a surgical intervention for breast cancer using local infiltration of anesthetics.

RESUMO

Anal fistulas often cause significant impairment to patients' health-related quality of life (HRQOL). This cross-sectional study aimed to compare the HRQOL between patients with anal fistulas with inflammatory bowel disease (IBD) and those without, hypothesizing significant differences in HRQOL scores between these groups. The secondary objectives were to identify specific aspects of life quality most affected and explore potential variables influencing HRQOL. The study was conducted at the Clinical Emergency Hospital "Pius Brinzeu" in Timisoara, Romania, using a convenience sample of 175 adult patients diagnosed with anal fistulas, stratified into IBD and non-IBD groups. Quality of life was evaluated at initial hospital admission and three months post-treatment using four questionnaires: SF-36, GIQLI, HADS, and the WHOQOL-BREF. Initial SF-36 scores were marginally lower in the IBD group, with mean physical and mental scores of 52.0 and 54.5, respectively. Both groups showed an improvement after intervention, but the mean difference was higher in the IBD group, with an increase of 1.1 in physical score. Initial GIQLI scores were significantly lower in the IBD group (110) compared to the non-IBD group (116). Post-intervention, the mean scores increased to 116 and 121, respectively. HADS scores suggested higher anxiety levels in the non-IBD group (7.5 vs. 6.1), although depression scores were similar. Post-intervention, anxiety scores decreased more substantially in the non-IBD group (-0.9 vs. -0.3). The WHOQOL-BREF scores were lower across all domains for the IBD group at the initial test (physical health: 12.4, psychological health: 14.9, social relationships: 14.4, environment: 13.0). Post-intervention, scores increased marginally in the IBD group (physical health: 12.7, psychological health: 15.9, social relationships: 14.1, environment: 13.8) but varied in the non-IBD group. HRQOL, as measured by multiple questionnaires, is impacted differently in anal fistula patients with and without IBD. These findings highlight the importance of a tailored approach to managing this patient population to improve their quality of life post-treatment.

RESUMO

INTRODUCTION: The antitumor host immune response is an important factor in breast cancer, but its role is not fully established. The role of tumor infiltrating lymphocytes (TIL) as an immunological biomarker in breast cancer has been significantly explored in recent years. The number of patients treated with neoadjuvant chemotherapy (NAC) has increased and the identification of a biomarker to predict the probability of pCR (pathological complete response) is a high priority. MATERIALS AND METHODS: We evaluated 334 cases of BC treated with NAC followed by surgical resection from 2020-2022 at the Ist Clinic of Oncological Surgery, Oncological Institute "Prof Dr I Chiricuta" Cluj Napoca. Of the above, 122 cases were available for histological evaluation both in pre-NAC biopsy and post-NAC resection tissue. Evaluation of biopsy fragments and resection parts were performed using hematoxylin eosin (H&E). The TIL evaluation took place according to the recommendations of the International TIL Working Group (ITILWG). RESULTS: There was a strong association between elevated levels of pre-NAC TIL. At the same time, there is a statistically significant correlation between stromal TIL and tumor grade, the number of lymph node metastases, the molecular subtype and the number of mitoses (p < 0.005). Intratumoral TIL showed a significant correlation with tumor size, distant metastasis, molecular subtype, number of mitosis, stage and lymph node metastasis (p < 0.005). We also demonstrated that high pre-NAC STIL represents a strong predictive marker for pCR. CONCLUSION: This study reveals the role of TIL as a predictive biomarker in breast cancer not only for the well-established TNBC (triple negative breast cancer) and HER2+ (Her2 overexpressed) subtypes but also in Luminal A and B molecular subtypes. In this scenario, the evaluation of sTIL as a novel predictive and therapy-predicting factor should become a routinely performed analysis that could guide clinicians when choosing the most appropriate therapy.

RESUMO

Due to the still large number of patients diagnosed with pelvic neoplasms (colorectal, gynecological, and urological) in advanced stages right from the initial diagnosis, surgery represents the mainstay of treatment, often implying wide, eventually multi-organ resections in order to achieve negative surgical margins. Perineal wound morbidity, particularly in extralevator abominoperineal excision, leads to complications and local infection rates of up to 40%. Strategies to reduce postoperative wound complications are being pursued to address this issue. The VRAM flap remains the gold standard for autologous reconstruction after pelvic oncological resection; it was initially designed for abdominal wall defects and later expanded for large pelvic tissue defects. The flap's application is based on its physical characteristics, including abundant tissue and a generous skin paddle, which effectively obliterates dead space after exenterations. The generous skin paddle offers good cosmetic and functional outcomes at the recipient site. This article describes the case of a patient histopathologically diagnosed with stage IIIA squamous cell carcinoma of the uterine cervix who received multimodal onco-surgical treatment. The surgical mainstay of this treatment is pelvic exenteration. Pelvic reconstruction after this major surgery was performed using a vertical flap with the rectus abdominis.

RESUMO

The predictions on the influence of the SARS-CoV-2 pandemic on access to medical services in Romania predicted a 35% drop in oncological hospitalizations in 2020 compared to the previous decade, raising the hypothesis that patients with colorectal cancer can become indirect victims of the ongoing pandemic. Therefore, the aim of the current research was to observe how the COVID-19 pandemic influenced colorectal cancer surgery in Romania, to determine the level of addressability towards specialized care, to compare the cancer staging between the pandemic and pre-pandemic periods, and to observe the risk factors for disease progression. This retrospective study was spread over three years, respectively, from March 2019 to March 2022, and included a total of 198 patients with a history of colorectal cancer surgery. It was decided to perform a parallel comparison of 2019, 2020, and 2021 to observe any significant changes during the pandemic. Our clinic encountered a significant decrease in all interventions during the pandemic; although the number of CRC surgeries remained constant, the cases were more difficult, with significantly more patients presenting in emergency situations, from 31.3% in 2019 to 50.0% in 2020 and 57.1% in 2021. Thus, the number of elective surgeries decreased significantly. The proportion of TNM (tumor-node-metastasis) staging was, however, statistically significant between the pre-pandemic and pandemic period. In 2019, 13.3% of patients had stage IIa, compared with 28.8% in 2020 and 13.1% in 2021. Similarly, the proportion of very advanced colorectal cancer was higher during the pandemic period of 2020 and 2021 (12.0% in 2019 vs. 12.5% in 2020 and 25.0% in 2021), which was represented by a significantly higher proportion of patients with bowel perforation. Patients with an advanced TNM stage had a 6.28-fold increased risk of disease progression, followed by lymphovascular invasion (HR = 5.19). However, the COVID-19 pandemic, represented by admission years 2020 and 2021, did not pose a significant risk for disease progression and mortality. In-hospital mortality during the pandemic also did not change significantly. After the pandemic restrictions have been lifted, it would be advisable to conduct a widespread colorectal cancer screening campaign in order to identify any instances of the disease that went undetected during the SARS-CoV-2 pandemic.

RESUMO

Endometriosis is a gynecological condition caused by the development of endometrial tissue outside the uterine cavity. Naturally, it commonly occurs at locations such as the ovaries and pelvic peritoneum. However, ectopic endometrial tissue may be discovered outside of the typical sites, suggesting the possibility of iatrogenic seeding after gynecological operations. Based on this hypothesis, we developed a study aiming to establish the root cause of atypical implantation of endometrial foci, as the main end point, and to determine diagnostic features and risk factors for this condition, as a secondary target. The research followed a retrospective design, including a total of 126 patients with endometriosis who met the inclusion criteria. A group of 71 patients with a history of c-section was compared with a control group of patients with endometriosis and no history of c-section. Endometriosis that developed inside or in close proximity to surgical incisions of asymptomatic patients before surgical intervention was defined as iatrogenic endometriosis. Compared with patients who did not have a c-section, the c-section group had significantly more minimally invasive pelvic procedures and multiple adhesions and endometriosis foci at intraoperative look (52.1% vs. 34.5%, respectively 52.1% vs. 29.1%). The most common location for endometriosis lesions in patients with prior c-section was the abdominal wall (42.2% vs. 5.4%), although the size of foci was significantly smaller by size and weight (32.2 mm vs. 34.8 mm, respectively 48.6 g vs. 53.1 g). The abdominal wall endometriosis was significantly associated with minimally invasive pelvic procedures (correlation coefficient = 0.469, p-value = 0.001) and c-section (correlation coefficient = 0.523, p-value = 0.001). A multivariate regression analysis identified prior c-section as an independent risk factor for abdominal wall endometriosis (OR = 1.85, p-value < 0.001). We advocate for strict protocols to be implemented and followed during c-section and minimally invasive procedures involving the pelvic region to ensure minimum spillage of endometrial cells. Further research should be developed to determine the method of abdominal and surgical site irrigation that can significantly reduce the risk of implantation of viable endometrial cells. Understanding all details of iatrogenic endometriosis will lead to the development of non-invasive disease diagnosis and minimally invasive procedures that have the potential to reduce postoperative complications.

RESUMO

In the field of oncology, the plant kingdom has an inexhaustible supply of bioactive compounds. Phytochemical compounds isolated from Helleborus species have been found to be useful in various chronic diseases. This has brought Helleborus to the attention of medical researchers. H. purpurascens is a plant characteristic of the Carpathian area, known since ancient times for its beneficial effects. The aim of the study was to evaluate the flavonoids composition of a hydroalcoholic extract of H. purpurascens, as well as to assess its antioxidant activity and antitumor potential at the level of two healthy cell lines and four tumor cell lines. In addition, the expression of the genes involved in the apoptotic process (Bcl-2, Bad, and Bax) were evaluated. The results indicated that the extract has a high concentration of flavonoids, such as epicatechin, quercetin, and kaempferol. The extract has an increased antioxidant activity, very similar to that of the standard, ascorbic acid and cytotoxic effects predominantly in the breast cancer cell line, being free of cytotoxic effects in healthy cell lines. Underlying the cytotoxic effect is the induction of the process of apoptosis, which in the present study was highlighted by decreasing the expression of anti-apoptotic genes (Bcl-2) and increasing the expression of pro-apoptotic genes (Bad and Bax). In conclusion, the hydroalcoholic extract of H. purpurascens can be considered an important source for future medical applications in cancer therapy.

RESUMO

The growth and development of the fetus is a complex phenomenon that can be influenced by several variables. High quantities of heavy metal ions in the amniotic fluid have been linked to poor health, especially in industrial, polluted and poor areas. The aim of the present study was to assess the differences in the concentration of these ions between preterm (weeks 15-37) and term pregnancies (starting at week 37). Another objective was to compare pregnancies from two cities with different industry levels. Two sample lots from two Romanian cities were analyzed. A total of 100 patients from Timisoara were compared with 60 from Petrosani, a heavy industry city in Romania. Demographic data were collected, and amniocentesis was performed on all women. Lead (Pb), copper (Cu), nickel (Ni), cadmium (Cd), arsenic (As), iron (Fe) and zinc (Zn) concentrations were assessed. Descriptive and analytical statistics were performed using the Mann-Whitney U test for non-parametric data and the Fisher's exact test for categorical data. In addition, categorical data was represented graphically. In the Timisoara cohort, the differences in heavy metal concentrations between preterm and term pregnancies were not statistically significant. In the Petrosani cohort, however, the concentrations of Zn (P=0.02606) and Cd (P=0.01512) were higher in preterm than in term pregnancies. When comparing the two cohorts as a whole, the concentration of Pb (P=0.04513), Cd (P=0.00002), As (P=0.03027) and Zn (P<0.00001) were higher in the patients from Petrosani than in those from Timisoara. Only Cu concentrations were higher in the Timisoara cohort (P<0.00001). The concentrations of Ni (P=0.78150) and Fe (P=0.44540) did not differ statistically. Thus, amniocentesis is an important diagnostic and exploratory tool in determining differences in the concentrations of elements such as heavy metal ions. Research over a longer period of time should be carried out to examine the relation between heavy metal ions concentration and possible postnatal health outcomes.

RESUMO

Around 20% of couples worldwide are affected by infertility issues, with numbers in the European Union reaching as high as 25%, while access to reproductive care varies significantly by geopolitical and country-specific variables. The purpose of this research is to shed light on the unique social, psychological, and financial difficulties faced by Romanian couples seeking access to assisted reproductive therapy (ART). A cross-sectional study was conducted between 2017 and 2019 to involve women who accessed ART at fertility clinics in Romania by completing two infertility surveys. We analyzed the data in terms of all facets of infertility and ART, including the effect of personal background and stress levels on succeeding to conceive, the impact of treatment costs, and household income. A total of 829 participants completed the survey. We observed that high stress exposure leads to a substantially higher duration to conceive using ART, although the proportions of successful pregnancies did not differ between low-stress and high-stress groups. A significantly higher number of couples achieved pregnancy when their monthly household income was higher than EUR 1000 and if the ART method was more expensive. Additionally, we observed that advanced age, high stress levels, and the high cost of ART had a negative association with achieving pregnancy using ART. The findings indicated that Romanian couples experiencing infertility must contend with significant expenses for specialist infertility treatments, as well as treatment-related stress, both of which have a detrimental effect on their odds of attaining conception.

RESUMO

Acute pancreatitis is an unpredictable disease affecting the pancreas and it is characterized by a wide range of symptoms and modified lab tests, thus there is a continuing struggle to classify this disease and to find risk factors associated with a worse outcome. The main objective of this study was to identify the risk factors associated with the fatal outcome of the intensive care unit's patients diagnosed and admitted for severe acute pancreatitis, the secondary objective was to investigate the prediction value for the death of different inflammatory markers at the time of their admission to the hospital. This retrospective study included all the patients with a diagnosis of acute pancreatitis admitted to the Intensive Care Unit of the Emergency County Hospital Timisoara between 1 January 2016 and 31 May 2021. The study included 53 patients diagnosed with severe acute pancreatitis, out of which 21 (39.6%) survived and 32 (60.4%) died. For the neutrophils/lymphocytes ratio, a cut-off value of 12.4 was found. When analyzing age, we found out that age above 52 years old can predict mortality, and for the platelets/lymphocytes ratio, a cut-off value of 127 was found. Combining the three factors we get a new model for predicting mortality, with an increased performance, AUROC = 0.95, p < 0.001. Multiple persistent organ failure, age over 50, higher values of C reactive protein, and surgery were risk factors for death in the patients with severe acute pancreatitis admitted to the intensive care unit. The model design from the neutrophils/lymphocytes ratio, platelets/lymphocytes ratio, and age proved to be the best in predicting mortality in severe acute pancreatitis.
